Early prediction of long-term survival of patients with nasopharyngeal carcinoma by multi-parameter MRI radiomics

Purpose

The objective is to create a comprehensive model that integrates clinical, semantic, and radiomics features to forecast the 5-year progression-free survival (PFS) of individuals diagnosed with non-distant metastatic Nasopharyngeal Carcinoma (NPC).

Methods

In a retrospective analysis, we included clinical and MRI data from 313 patients diagnosed with primary NPC. Patient classification into progressive and non-progressive categories relied on the occurrence of recurrence or distant metastasis within a 5-year timeframe. Initial screening comprised clinical features and statistically significant image semantic features. Subsequently, MRI radiomics features were extracted from all patients, and optimal features were selected to formulate the Rad-Score.Combining Rad-Score, image semantic features, and clinical features to establish a combined model Evaluation of predictive efficacy was conducted using ROC curves and nomogram specific to NPC progression. Lastly, employing the optimal ROC cutoff value from the combined model, patients were dichotomized into high-risk and low-risk groups, facilitating a comparison of 10-year overall survival (OS) between the groups.

Results

The combined model showcased superior predictive performance for NPC progression, reflected by AUC values of 0.84, an accuracy rate of 81.60%, sensitivity at 0.77, and specificity at 0.81 within the training group. In the test set, the AUC value reached 0.81, with an accuracy of 74.6%, sensitivity at 0.82, and specificity at 0.66.

Conclusion

The amalgamation of Rad-Score, clinical, and imaging semantic features from multi-parameter MRI exhibited significant promise in prognosticating 5-year PFS for non-distant metastatic NPC patients. The combined model provided quantifiable data for informed and personalized diagnosis and treatment planning.

Long-term continuations rate of ring pessary use for symptomatic pelvic organ prolapse

PURPOSE

To evaluate long-term continuation rates, adverse events of ring pessary use at a minimum of 5 years follow-up, and factors associated with discontinuation in symptomatic pelvic organ prolapse (POP).

METHODS

Women with symptomatic POP who were treated with vaginal ring pessary and had successful fittings were included. Adverse events and reasons for discontinuation of pessary use were recorded. Patients who were lost to follow-up were defined as discontinuation.

RESULTS

During 12 year-period, 239 of 329 POP patients (72.6%) had successful fittings with ring pessary. The mean age was 67.8 ± 8.9 years (range 27-86) and 70% of patients had advanced stage. The cumulative probability of continued ring pessary use was 84.1%, 64.4%, 49.3%, and 33.5%, at 1, 3, 5, and 10 years, respectively. Most common reason for discontinuation was frequent expulsion (21.6%), followed by vaginal erosion (16.5%), no prolapse improvement (12.4%), and inability or inconvenience to do self-care (9.3%). However, 9 patients (9.3%) had improvement of prolapse and were able to discontinue pessary insertion. Age above 70 years, wide introitus, and incapability of self-care are independent factors associated with long-term discontinuation. Adverse events occurred in 23.4% of patients, 18.8% of them had vaginal erosion, 11.7% vaginal discharge/infection, and 18.4% de novo SUI. However, no statistical significance existed between those who continued and discontinued pessary use due to these adverse events.

CONCLUSION

Ring pessary is an effective treatment in symptomatic POP, with acceptable long-term continuation rates and minor adverse events. Self-care of pessary is very important aiming to minimize adverse events. Advanced age, wide introitus and incapability of self-care were associated factors for long-term discontinuation.

Long-term outcomes after paediatric sepsis: A narrative review

OBJECTIVES

Sepsis is one of the leading causes of mortality in the paediatric population. However, knowledge is limited around morbidity in childhood sepsis survivors. The aim of this review is to identify and critically appraise the evidence for long-term outcomes in paediatric survivors of sepsis using the Post Intensive Care Syndrome - paediatrics (PICS-p) framework.

METHODS

A search for studies was undertaken in the electronic databases PubMed and Cumulative Index to Nursing and Allied Health Literature from 2010. Criteria for inclusion are as follows: participants >28 d adjusted age, diagnosed with sepsis, and follow-up after hospital discharge using a validated outcome measure. The PICS-p subdomains (cognitive, physical, emotional, and social) guided thematic synthesis of current literature. Study quality was assessed using the Newcastle-Ottawa Scale.

RESULTS

In total, nine studies, involving 2136 children, using 13 different outcome measures were included in the review. Mean follow-up time was 28 d after hospital discharge with a range of 7 d to 12 m across the PICS-p domains. Physical functioning was the most examined domain explored in six studies that used four outcome measures. Morbidity in physical, cognitive, and emotional domains was still evident at 9-12 m. No literature identified explored social health.

CONCLUSION(S)

Overall, we identified a wide range of measures, administered at various time points in studies of sepsis survivorship in childhood. Variation in follow-up timepoints, validated tools, and restricted outcome measures highlighted the lack in understanding of this priority area. Furthermore, long-term outcome research and a cohesive understanding across all the PICS-p domains are needed to better understand this population.

Cyclosporine A-induced systemic metabolic perturbations in rats: A comprehensive metabolome analysis

A better understanding of cyclosporine A (CsA)-induced nephro- and hepatotoxicity at the molecular level is necessary for safe and effective use. Utilizing a sophisticated study design, this study explored metabolic alterations after long-term CsA treatment in vivo. Rats were exposed to CsA with 4, 10, and 25 mg/kg for 4 weeks and then sacrificed to obtain liver, kidney, urine, and serum for untargeted metabolomics analysis. Differential network analysis was conducted to explore the biological relevance of metabolites significantly altered by toxicity-induced disturbance. Dose-dependent toxicity was observed in all biospecimens. The toxic effects were characterized by alterations of metabolites related to energy metabolism and cellular membrane composition, which could lead to the cholestasis-induced accumulation of bile acids in the tissues. The unfavorable impacts were also demonstrated in the serum and urine. Intriguingly, phenylacetylglycine was increased in the kidney, urine, and serum treated with high doses versus controls. Differential correlation network analysis revealed the strong correlations of deoxycytidine and guanosine with other metabolites in the network, which highlighted the influence of repeated CsA exposure on DNA synthesis. Overall, prolonged CsA administration had system-level dose-dependent effects on the metabolome in treated rats, suggesting the need for careful usage and dose adjustment.

Long-term outcomes after endoscopic removal of malignant colorectal polyps: Results from a 10-year cohort

BACKGROUND

Choosing an optimal post-polypectomy management strategy of malignant colorectal polyps is challenging, and evidence regarding a surveillance-only strategy is limited.

AIM

To evaluate long-term outcomes after endoscopic removal of malignant colorectal polyps.

METHODS

A single-center retrospective cohort study was conducted to evaluate outcomes after endoscopic removal of malignant colorectal polyps between 2010 and 2020. Residual disease rate and nodal metastases after secondary surgery and local and distant recurrence rate for those with at least 1 year of follow-up were investigated. Event rates for categorical variables and means for continuous variables with 95% confidence intervals were calculated, and Fisher’s exact test and Mann-Whitney test were performed. Potential risk factors of adverse outcomes were determined with univariate and multivariate logistic regression models.

RESULTS

In total, 135 lesions (mean size: 22.1 mm; location: 42% rectal) from 129 patients (mean age: 67.7 years; 56% male) were enrolled. The proportion of pedunculated and non-pedunculated lesions was similar, with en bloc resection in 82% and 47% of lesions, respectively. Tumor differentiation, distance from resection margins, depth of submucosal invasion, lymphovascular invasion, and budding were reported at 89.6%, 45.2%, 58.5%, 31.9%, and 25.2%, respectively. Residual tumor was found in 10 patients, and nodal metastasis was found in 4 of 41 patients who underwent secondary surgical resection. Univariate analysis identified piecemeal resection as a risk factor for residual malignancy (odds ratio: 1.74; P = 0.042). At least 1 year of follow-up was available for 117 lesions from 111 patients (mean follow-up period: 5.59 years). Overall, 54%, 30%, 30%, 11%, and 16% of patients presented at the 1-year, 3-year, 5-year, 7-year, and 9-10-year surveillance examinations. Adverse outcomes occurred in 9.0% (local recurrence and dissemination in 4 patients and 9 patients, respectively), with no difference between patients undergoing secondary surgery and surveillance only.

CONCLUSION

Reporting of histological features and adherence to surveillance colonoscopy needs improvement. Long-term adverse outcome rates might be higher than previously reported, irrespective of whether secondary surgery was performed.

Effect of intra-arrest transport, extracorporeal cardiopulmonary resuscitation and immediate invasive assessment in refractory out-of-hospital cardiac arrest: a long-term follow-up of the Prague OHCA trial

BACKGROUND

Randomized data evaluating the impact of the extracorporeal cardiopulmonary resuscitation (ECPR) approach on long-term clinical outcomes in patients with refractory out-of-hospital cardiac arrest (OHCA) are lacking. The objective of this follow-up study was to assess the long-term clinical outcomes of the ECPR-based versus CCPR approach.

METHODS

The Prague OHCA trial was a single-center, randomized, open-label trial. Patients with witnessed refractory OHCA of presumed cardiac origin, without return of spontaneous circulation, were randomized during ongoing resuscitation on scene to conventional CPR (CCPR) or an ECPR-based approach (intra-arrest transport, ECPR if ROSC is not achieved prehospital and immediate invasive assessment).

RESULTS

From March 2013 to October 2020, 264 patients were randomized during ongoing resuscitation on scene, and 256 patients were enrolled. Long-term follow-up was performed 5.3 (interquartile range 3.8-7.2) years after initial randomization and was completed in 255 of 256 patients (99.6%). In total, 34/123 (27.6%) patients in the ECPR-based group and 26/132 (19.7%) in the CCPR group were alive (log-rank P = 0.01). There were no significant differences between the treatment groups in the neurological outcome, survival after hospital discharge, risk of hospitalization, major cardiovascular events and quality of life. Of long-term survivors, 1/34 (2.9%) in the ECPR-based arm and 1/26 (3.8%) in the CCPR arm had poor neurological outcome (both patients had a cerebral performance category score of 3).

CONCLUSIONS

Among patients with refractory OHCA, the ECPR-based approach significantly improved long-term survival. There were no differences in the neurological outcome, major cardiovascular events and quality of life between the groups, but the trial was possibly underpowered to detect a clinically relevant difference in these outcomes.

Long-term follow up of alemtuzumab-treated patients: a retrospective study in a Belgian tertiary care center

BACKGROUND

Pivotal studies have reported a significant proportion of patients achieving no evidence of disease activity (NEDA) after 2 cycles of treatment with alemtuzumab (ATZ), that can be maintained for several years. Long-term real-world evidence regarding ATZ as well as subsequent treatment trajectories is still scarce.

OBJECTIVE

To analyze the effectiveness and safety of ATZ-treated patients in a tertiary care Belgian center.

METHODS

A retrospective cohort study including 32 patients treated with ATZ between 2015 and 2021 was performed.

RESULTS

32 patients received 2 ATZ courses with a mean follow-up (FU) duration of 5.6 years (range: 2.25-8.2). 21.75% patients were treatment naïve. 40.5% were previously treated with natalizumab or fingolimod. NEDA-3 was achieved in 61.3-85% of patients, with failure mostly attributed to recurrence of radiological disease activity. During FU, annualized relapse rates remained very low (0.06-0.14), disability improvement occurred in up to 40.5%, whereas disability worsening occurred in up to 13.5%. Retreatment risk was associated with younger age (< 45 years old, Odds Ratio 8.0, p = 0.02) and a higher number of previous DMTs (Hazard ratio 2.7, 95%CI 1.3-7.4, p = 0.02). Safety in our cohort was consistent with the known profile of ATZ. At the end of FU, 65.6% patients remained untreated after 2 or 3 courses of ATZ, while the remaining switched to anti-CD20 therapy or cladribine.

CONCLUSION

ATZ is a high efficacy therapy for active MS, providing long-term remission in a significant proportion of patients. Retreatment was more frequent in younger patients or patients having failed a higher number of previous DMTs.

Effects of long-term indoor air purification intervention on cardiovascular health in elderly: a parallel, double-blinded randomized controlled trial in Hong Kong

Ambient fine particulate matter (PM2.5) is a leading environmental risk factor globally, and over half of the associated disease burden are caused by cardiovascular disease. Numerous randomized controlled trials (RCT) have investigated the short-term cardiovascular benefits of indoor air purifiers (IAPs), but major knowledge gaps remain on their longer-term benefits. In this 1-year, randomized, double-blinded, parallel controlled trial of 47 elderly (ntrue-purification = 24; nsham-purification = 23) aged ≥70 years, true-purification reduced household PM2.5 levels by 28% and maintained lower exposure throughout the year compared to the sham-purification group. After 12 months of intervention, a significant reduction of diastolic blood pressure was found in the true-purification versus sham-purification group (-4.62 [95% CI: -7.28, -1.96] mmHg) compared to baseline measurement prior to the intervention, whereas systolic blood pressure showed directionally consistent but statistically non-significant effect (-2.49 [95% CI: -9.25, 4.28] mmHg). Qualitatively similar patterns of associations were observed for pulse pressure (-2.30 [95% CI: -6.57, 1.96] mmHg) and carotid intima-media thickness (-10.0% [95% CI: -24.8%, 4.7%]), but these were not statistically significant. Overall, we found suggestive evidence of cardiovascular benefits of long-term IAPs use, particularly on diastolic blood pressure. Evidence on other longer-term cardiovascular traits is less clear. Further trials with larger sample sizes and long-term follow-up are needed across diverse populations to evaluate the cardiovascular benefits of IAPs.

Agricultural fertilization near marshes impacts the potential for greenhouse gas emissions from wetland ecosystems by modifying microbial communities

Ensuring agricultural security and preserving the health of wetland ecosystems are crucial concerns facing northeast China. However, the adverse effects of environmental pollution, especially nitrogen (N), caused by prolonged agricultural development on the health of marsh wetlands cannot be systematically recognized. To address this issue, an 18-year trial with four different levels of N application was carried out in a typical area of the Northeast region: 0, 6, 12, and 24 gN·m-2·a-1 (referred to as CK, N6, N12, and N24, respectively) to investigate changes in wetland ecological functioning. The results showed that long-term N input significantly enhanced soil N availability. High-level of N addition (N24) significantly reduced soil bacterial richness in October, while fungal diversity was significantly higher in June than in October for both control and N6 treatments. The main environmental factors affecting microorganisms in June were TN, NH4+, and EC, while bacterial and fungal communities were influenced by TN and Leaf Area Index (LAI), respectively, in October. It was found that the AN16S gene was significantly higher in June than in October, indicating that summer is the critical time for N removal in the wetland. N addition significantly reduced the abundance of the NIFH gene and decreased the N fixation potential of the wetland. In June, low and medium levels of N inputs promoted denitrification processes in the wetland and elevated the wetland N2O emission potential. The abundance of NARG, NIRK, and NOSZ genes decreased significantly in October compared to June, indicating a decrease in the wetland N2O emission potential. Additionally, it was observed that soil methanotrophs were positively affected by NH4+ and TN in October, thereby reducing the wetland CH4 emission potential. Our research provides a systematic understanding of the impact of agricultural N pollution on marsh wetlands, which can inform strategies to protect wetland health.

"So at least now I know how to deal with things myself, what I can do if it gets really bad again"-experiences with a long-term cross-sectoral advocacy care and case management for severe multiple sclerosis: a qualitative study

BACKGROUND

Persons with severe Multiple Sclerosis (PwsMS) face complex needs and daily limitations that make it challenging to receive optimal care. The implementation and coordination of health care, social services, and support in financial affairs can be particularly time consuming and burdensome for both PwsMS and caregivers. Care and case management (CCM) helps ensure optimal individual care as well as care at a higher-level. The goal of the current qualitative study was to determine the experiences of PwsMS, caregivers and health care specialists (HCSs) with the CCM.

METHODS

In the current qualitative sub study, as part of a larger trial, in-depth semi-structured interviews with PwsMS, caregivers and HCSs who had been in contact with the CCM were conducted between 02/2022 and 01/2023. Data was transcribed, pseudonymized, tested for saturation and analyzed using structuring content analysis according to Kuckartz. Sociodemographic and interview characteristics were analyzed descriptively.

RESULTS

Thirteen PwsMS, 12 caregivers and 10 HCSs completed interviews. Main categories of CCM functions were derived deductively: (1) gatekeeper function, (2) broker function, (3) advocacy function, (4) outlook on CCM in standard care. Subcategories were then derived inductively from the interview material. 852 segments were coded. Participants appreciated the CCM as a continuous and objective contact person, a person of trust (92 codes), a competent source of information and advice (on MS) (68 codes) and comprehensive cross-insurance support (128 codes), relieving and supporting PwsMS, their caregivers and HCSs (67 codes).

CONCLUSIONS

Through the cross-sectoral continuous support in health-related, social, financial and everyday bureaucratic matters, the CCM provides comprehensive and overriding support and relief for PwsMS, caregivers and HCSs. This intervention bears the potential to be fine-tuned and applied to similar complex patient groups.

TRIAL REGISTRATION

The study was approved by the Ethics Committee of the University of Cologne (#20-1436), registered at the German Register for Clinical Studies (DRKS00022771) and in accordance with the Declaration of Helsinki.

Brain magnetic resonance imaging findings six months after critical COVID-19: A prospective cohort study

BACKGROUND

COVID-19 patients suffered from neurological symptoms in the acute phase. Whether this led to long-term consequences was unknown. We studied long-term brain MRI findings in ICU-treated COVID-19 patients and compared them with findings in groups with less severe acute disease.

MATERIALS AND METHODS

In this prospective cohort study, 69 ICU-treated, 46 ward-treated, and 46 home-isolated patients, as well as 53 non-COVID-19 controls, underwent brain MRI six months after acute COVID-19. Plasma neurofilament light chain (NfL), a biomarker of neuroaxonal injury, was measured simultaneously.

RESULTS

Ischaemic infarctions existed in 5.8% of ICU-treated patients. Cerebral microbleeds (CMBs) existed in 27 (39.1%) ICU-treated, 13 (28.3%) ward-treated, 8 (17.4%) home-isolated COVID-19 patients, and 12 (22.6%) non-COVID controls. Patients with CMBs were older (p < 0.001), had a higher level of plasma NfL (p = 0.003), and higher supplementary oxygen days (p < 0.001). In multivariable analysis, age (OR 1.06, 95% CI 1.02-1.09) and supplementary oxygen days (OR 1.07, 95% CI 1.02-1.13) were associated with CMBs. The ICU group showed prevalent distribution of CMBs in deep regions.

CONCLUSION

Age and supplementary oxygen days were independently associated with CMBs; COVID-19 status showed no association. Accumulation of risk factors in the ICU group may explain the higher prevalence of CMBs.

7-Year Efficacy and Safety of iStent inject Trabecular Micro-Bypass in Combined and Standalone Usage

INTRODUCTION

This study evaluated 7-year effectiveness and safety of second-generation trabecular micro-bypass implantation (iStent inject) either in combination with cataract surgery or as a standalone procedure (Combined or Standalone subgroups, respectively) in eyes with open-angle glaucoma.

METHODS

This prospective, non-randomized, unmasked, longitudinal study included 125 consecutive iStent inject cases of a single surgeon at a large German academic hospital. Patients had considerable preoperative disease burden, with mean intraocular pressure (IOP) of 23.5 mmHg, 84.8% of eyes on ≥ 2 medications, and 38.4% of eyes with prior glaucoma surgery. IOP, medications, adverse events, and secondary surgeries were assessed through 7 years in the Overall cohort and in Combined (n = 81) and Standalone (n = 44) subgroups.

RESULTS

Over 7-year follow-up, mean IOP decreased by 36.2-40.0% in Overall eyes, 34.1-38.9% in Combined eyes, and 39.5-43.5% in Standalone eyes (p < 0.001 at all timepoints for all groups). Meanwhile, mean medications decreased by 59.3-71.3% in Overall eyes, 57.9-69.0% in Combined eyes, and 62.1-76.2% in Standalone eyes (p < 0.001 at all timepoints in all groups). At last follow-up (mean 77.4 months; 92.8% of patients with last visit at 6 or 7 years), 83.7% of Overall eyes, 82.3% of Combined eyes, and 86.4% of Standalone eyes had achieved ≥ 20% IOP reduction vs preoperative. At last follow-up vs preoperative, 100% of eyes in all groups had the same or lower IOP and 100% had the same or lower medication regimen. Safety outcomes were favorable, with no filtration surgeries and only 4.84% of eyes experiencing clinically significant visual field loss over 7 years of follow-up.

CONCLUSION

iStent inject implantation with or without phacoemulsification produced significant and durable 7-year reductions in IOP (~ 34-44% reduction) and medications (~ 58-76% reduction) while preventing filtering surgery in this cohort of patients with relatively high preoperative disease burden. Combined and Standalone cases had similarly favorable effectiveness and safety.

Very long-term effects of conservatively treated blunt thoracic trauma: A retrospective analysis

INTRODUCTION

Despite the high incidence of blunt thoracic trauma and frequently performed conservative treatment, studies on very long-term consequences for these patients remain sparse in current literature. In this study, we identify prevalence of long-term morbidity such as chronic chest pain, shortness of breath, and analyze the effect on overall quality of life and health-related quality of life.

METHODS

Questionnaires were send to patients admitted for blunt thoracic trauma at our institution and who were conservatively treated between 1997 and 2019. We evaluated the presences of currently existing chest pain, persistence of shortness of breath after their trauma, the perceived overall quality of life, and health-related quality of life. Furthermore, we analyzed the effect of pain and shortness of breath on overall quality of life and health-related quality of life.

RESULTS

The study population consisted of 185 trauma patients with blunt thoracic trauma who were admitted between 1997 and 2019, with a median long term follow up of 11 years. 60 percent still experienced chronic pain all these years after trauma, with 40,7 percent reporting mild pain, 12,1 percent reporting moderate pain, and with 7,7 percent showing severe pain. 18 percent still experienced shortness of breath during exercise. Both pain and shortness of breath showed no improvement in this period. Pain and shortness of breath due to thoracic trauma were associated with a lower overall quality of life and health-related quality of life.

CONCLUSION

Chronic pain and shortness of breath may be relatively common long after blunt thoracic trauma, and are of influence on quality of life and health-related quality of life in patients with conservatively treated blunt thoracic trauma.

Long-Term Safety of Dupilumab in Patients With Moderate-to-Severe Asthma: TRAVERSE Continuation Study

BACKGROUND

Previous clinical trials have demonstrated dupilumab efficacy and safety in adults and adolescents with moderate to severe asthma for up to 3 years.

OBJECTIVE

The TRAVERSE continuation study (NCT03620747), a single-arm, open-label study, assessed safety and tolerability of dupilumab 300 mg every 2 weeks up to an additional 144 weeks (∼3 years) in patients with moderate to severe asthma who previously completed TRAVERSE (NCT02134028).

METHODS

Primary end points were incidence and event rates per 100 patient-years of treatment-emergent adverse events (TEAEs). Secondary end points included adverse events (AEs) of special interest, serious AEs, and AEs leading to study discontinuation.

RESULTS

A total of 393 patients participated in the TRAVERSE continuation study (cumulative dupilumab exposure, 431.7 patient-years; median treatment duration, 309 days). A total of 29 patients (7.4%) received more than 958 days of treatment. A total of 214 (54.5%) patients reported at least 1 TEAE (event rate: 171.4); 37 (9.4%) experienced at least 1 treatment-related TEAE, none of which were considered severe; 2 patients reported 6 TEAEs of moderate intensity. A total of 22 (5.6%) patients reported serious AEs (event rate: 6.9). AEs of special interest were reported in 24 patients (6.1%; event rate: 6.0). Five (1.3%) deaths occurred (event rate: 1.2) following serious AEs of coronavirus disease 2019 (COVID-19)-related pneumonia (3 patients), pancreatitis (1 patient), and pulmonary embolism (1 patient). None of the TEAEs leading to death were considered treatment-related.

CONCLUSIONS

Dupilumab treatment was well tolerated for up to an additional 3 years. Safety findings were consistent with the known safety profile of dupilumab. These findings further support the long-term use of dupilumab in patients with moderate to severe asthma.

One-year follow-up of COVID-19 recoverees with impaired pulmonary function: A prospective cohort study

Decreased diffusion capacity for carbon monoxide (DLCO) is the most prevalent pulmonary testing abnormality among COVID-19 recoverees. We prospectively followed 51 individuals with impaired DLCO at an average of ∼3 months following COVID-19 and re-examined them at one year. At follow-up, mean DLCO increased from 68.0 % to 72.6 % (p = 0.002); while 33 % of the cohort experienced a clinically significant rise (>10 points) in DLCO, only 29 % normalized their values. While DLCO change did not correlate with symptoms, lack of improvement was more prevalent among individuals with obesity. Regardless of COVID-19 severity, a substantial proportion continued to exhibit DLCO impairment at 1-year.

Risk factors for long-term mortality after acute aortic dissection-results of the German registry for acute aortic dissection type a long-term follow-up

OBJECTIVES

Several short-term analyses from German Registry for Acute Aortic Dissection Type A (GERAADA) have been published. This study investigated whether short-term risk factors are transferable to the long-term prognosis of patients.

METHODS

Thirty-three centres with 2686 patients participated in the long-term follow-up. A total of 1164 patients died, 1063 survived and 459 were lost to follow-up during the follow-up timeframe (mean duration: 10.2 years). Long-term mortality of the cohort was compared with an age-stratified, German population.

RESULTS

One, 5 and 10 years after initial surgery, the survival of the GERAADA patient cohort was 71.4%, 63.4% and 51%, respectively. Without the early deaths (90-day mortality 25.4%), survival was calculated after 1, 5 and 10 years: 95.6%, 83.5% and 68.3%. Higher age, longer extracorporeal circulation time, shorter perioperative ventilation time and postoperative neurologic deficits were predictive of long-term prognosis. In an age-divided landmark analysis, the mortality of aortic dissection surgery survivors was found to be similar to that of the general German population. If patients are sorted in risk groups according to the GERAADA score, long-term survival differs between the risk groups.

CONCLUSIONS

If patients have survived an acute postoperative period of 90 days, life expectancy comparable to that of the general German population can be assumed in lower- and medium-risk patients. Whether the GERAADA score can provide valuable insights into the long-term prognosis of patients undergoing surgery for acute aortic dissection type A is still unclear.

Time trends and outcomes of gastrostomy placement in a Swedish national cohort over two decades

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) and laparoscopically inserted gastrostomy have become the gold standard for adult patients and children, respectively, requiring long-term enteral nutrition support. Procedure-related mortality is a rare event, often reported to be zero in smaller studies. National data on 30-d mortality and long-term survival rates after gastrostomy placement are scarce in the literature.

AIM

To study the use of gastrostomies in Sweden from 1998-2019 and to analyze procedure-related mortality and short-term (< 30 d) and long-term survival.

METHODS

In this retrospective, population-based cohort study, individuals that had received a gastrostomy between 1998-2019 in Sweden were included. Individuals were identified in the Swedish National Patient Register, and survival analysis was possible by cross-referencing the Swedish Death Register. The cohort was divided into three age groups: Children (0-18 years); adults (19-64 years); and elderly (≥ 65 years). Kaplan-Meier with log-rank test and Cox regression were used for survival analysis.

RESULTS

In total 48682 individuals (52% males, average age 60.9 ± 25.3 years) were identified. The cohort consisted of 12.0% children, 29.5% adults, and 58.5% elderly. An increased use of gastrostomies was observed during the study period, from 13.7/100000 to 22.3/100000 individuals (P < 0.001). The use of PEG more than doubled (about 800 to 1800/year), with a corresponding decrease in open gastrostomy (about 700 to 340/year). Laparoscopic gastrostomy increased more than ten-fold (about 20 to 240/year). Overall, PEG, open gastrostomy, and laparoscopic gastrostomy constituted 70.0% (n = 34060), 23.3% (n = 11336), and 4.9% (n = 2404), respectively. Procedure-related mortality was 0.1% (n = 44) overall (PEG: 0.05%, open: 0.24%, laparoscopic: 0.04%). The overall 30-d mortality rate was 10.0% (PEG: 9.8%, open: 12.4%, laparoscopic: 1.7%) and decreased from 11.6% in 1998-2009 vs 8.5% in 2010-2019 (P < 0.001). One-year and ten-year survival rates for children, adults, and elderly were 93.7%, 67.5%, and 42.1% and 79.9%, 39.2%, and 6.8%, respectively. The most common causes of death were malignancies and cardiovascular and respiratory diseases.

CONCLUSION

The annual use of gastrostomies in Sweden increased during the study period, with a shift towards more minimally invasive procedures. Although procedure-related death was rare, the overall 30-d mortality rate was high (10%). To overcome this, we believe that patient selection should be improved.

Do Six-Week Postoperative Patient-Reported Outcomes Predict Long-Term Clinical Outcomes Following Lumbar Decompression?

BACKGROUND

Little research has been done to evaluate the prognostic value of short-term postoperative patient-reported outcomes (PROs) on long-term PROs following lumbar decompression (LD). We evaluated the prognostic value of short-term PROs on long-term PROs through 2 years after LD.

METHODS

A single spine surgeon database was retrospectively queried for patients undergoing primary LD with 6-week postoperative PROs reported. The demographics, perioperative traits, and preoperative, 6-month, 1-year, and 2-year PROs were recorded. The PROs included the visual analog scale (VAS) for back pain, VAS for leg pain, PRO measure information system for physical function (PROMIS-PF), and Oswestry disability index. Two-step multivariate linear regression was performed to determine the predictive value of 6-week PROs for the 6-month, 1-year, and 2-year PROs.

RESULTS

A total of 277 patients were included. The 6-week Oswestry disability index, VAS for leg pain, and 9-item patient health questionnaire (PHQ-9) are all positive predictors for their respective outcomes at 6 months. Additionally, the 6-week PROMIS-PF was a negative predictor of the 6-month PHQ-9. The 6-week PROMIS-PF positively predicted the PROMIS-PF through 1 year, and the PHQ-9 was a positive predictor of the PHQ-9 at 1 and 2 years postoperatively.

CONCLUSIONS

The 6-week postoperative PROs are predictive of the same outcomes at 6 months, the PROMIS-PF is predictive through 1 year, and the PHQ-9 is predictive through 2 years. Determining the predictive value of early postoperative PROs can be helpful in understanding the likely postoperative trajectory following LD and informing patient expectations.

Efficacy of Paravertebral Injection of Interferon-α2b Combined with High-Voltage, Long-Term Pulsed Radiofrequency in DRG in Mitigation of Postherpetic Neuralgia: A Retrospective Study

OBJECTIVE

This investigation aims to evaluate the effectiveness of the paravertebral injection of recombinant human interferon-α2b in conjunction with high-voltage, long-term, pulsed radiofrequency (PRF) in the dorsal root ganglion for the mitigation of postherpetic neuralgia (PHN).

METHODS

This retrospective study included 84 individuals with acute PHN. The participants were divided into 3 groups. Group H was treated with interferon-α2b combined with high-voltage long-term PRF. Group C was treated with a combination of high-voltage, long-term PRF and a paravertebral injection (without recombinant human interferon-α2b), and group I was treated with interferon-α2b only. All the patients in the 3 groups were orally administered a 5-mg morphine hydrochloride quick-release tablet when a burst of pain occurred during treatment. The numerical rating scale for pain score, the interleukin-6 and galectin-3 levels, and the incidence of PHN were documented before and after therapy.

RESULTS

The pain intensity of all individuals decreased after therapy. Compared with group C, the numerical rating scale scores for group H were significantly reduced at 4, 8, and 12 weeks following therapy, and the PHN incidence was significantly lower. Compared with prior treatment, the recommended dosage of gabapentin capsules and immediate-release morphine hydrochloride tablets was reduced for group H. Compared with group C, the requirement for orally administrated gabapentin capsules and morphine hydrochloride tablets in group H was reduced significantly after treatment. No serious adverse reactions occurred in any of the 3 groups.

CONCLUSIONS

Within the context of treatment of acute PHN, the injection of interferon-α2b in conjunction with high-voltage, long-term application of PRF is more effective than PRF or the injection of interferon-α2b alone.

Patient-reported outcome measures more than fifteen years after treatment of sagittal or metopic craniosynostosis: a prospective cohort study

PURPOSE

To evaluate the long-term anthropometric measurements, cosmetic satisfaction, and other patient-reported outcome measures (PROMs) of patients who underwent surgical treatment or observation only of sagittal or metopic single-suture craniosynostosis (SSC).

METHODS

A prospective study was designed for all patients diagnosed with non-syndromic sagittal and metopic craniosynostosis at the British Columbia Children's Hospital, Vancouver, Canada, in the period July 1986 to July 2006. After a minimum of 15 years post-diagnosis, all eligible patients were invited to fill out the Craniofacial Surgery Outcomes Questionnaire (CSO-Q) and to attend a scheduled follow-up appointment for the collection of anthropometric measurements. A descriptive analysis of the cosmetic results was performed. Statistical analyses compared the differences in anthropometric measurements between treated and non-treated patients.

RESULTS

Of the 253 eligible patients, 52 participants were willing to share patient data for use in the study. Of those 52 former patients, 36 (69.2%) filled out and returned the CSO-Q and 23 (44.2%) attended the follow-up appointment. The mean follow-up period between surgical treatment and the CSO-Q was 20.2 ± 2.5 years and between surgical treatment and the follow-up appointment was 20.9 ± 2.7 years. In patients with sagittal SSC, the mean cephalic index (CI) was significantly larger in treated than in non-treated patients (74.6 versus 69.1, p = 0.04), while the mean pupillary distance and forehead to back index were significantly smaller (pupillary distance 6.0 cm versus 6.7 cm [p = 0.04] and forehead to back index 19.6 cm versus 21.1 cm [p = 0.03]). Focusing more on the patient reported outcome measures, overall cosmetic satisfaction was found to be high (80.6%) and no differences were found between sagittal and metopic synostosis patients, nor between treated or non-treated craniosynostosis patients. Overall outcomes regarding self-esteem (RSES) and fear of negative evaluation (FNE) were comparable with population based outcomes.

CONCLUSION

This is the first prospective study of sagittal and metopic craniosynostosis patients regarding long-term anthropometric outcome and patient reported outcome measures, including patients who were treated surgically and those who received observation only. Although study participation two decades after initial diagnosis was difficult to obtain, our data provide a platform from which one can develop an inclusive and uniform approach to assess patients' subjective cosmetic satisfaction using the CSO-Questionnaire and might be useful in preoperative counseling and psychosocial care for patients and their families.

Rituximab as a sole steroid-sparing agent in generalized myasthenia gravis: Long-term outcomes

BACKGROUND

Rituximab, a B-cell depleting monoclonal antibody, represents an option for the treatment of refractory myasthenia gravis (MG). Its use is more established in muscle-specific tyrosine kinase positive (MuSK +) patients, while its role in managing acetylcholine receptor positive (AChR +), or double seronegative (DSN) patients, remains less clear. This study evaluates the long-term effectiveness and safety of rituximab in MG of various serotypes.

METHODS

We conducted an open-label study of MG patients receiving rituximab. Adults with generalized refractory MG, either anti-AChR + or DSN, and anti-MuSK + , refractory or not, who had follow-up > 12 months were selected. Change in quantitative myasthenia gravis (QMG) score at last follow-up, compared with baseline was a primary outcome, as well as factors affecting response to treatment. Secondary outcomes included, long-term safety, the steroid-sparing effect and relapse rates post-rituximab.

RESULTS

Thirty patients (16 anti-AChR + , 6 anti-MuSK + , 8 DSN) followed for a mean of 33.3 months were included. Mean scores pre-rituximab compared to last follow-up significantly decreased (p < 0.001), from 11 ± 4.1 to 4.3 ± 3.8, and from 1.9 to 0.3 regarding QMG and relapse rate per patient/year, respectively, while in 93.1% a daily steroid dose ≤ 10 mg was achieved. Antibody status was the only factor independently influencing several endpoints. Throughout the study period no crises or deaths occurred.

CONCLUSION

The present study supports that rituximab is an effective and well tolerated treatment for refractory anti-AChR + and DSN MG patients, while anti-MuSK + remains the group experiencing the greater benefits.

Predictive Factors of Pain and Functional Outcome 5-year Following Total Hip Arthroplasty: A Prospective FORCE-TJR Cohort Study

INTRODUCTION

Previous reports have identified a number of potential predictors of pain and function after total hip arthroplasty (THA). However, the results of these studies were conflicting, and most had a short follow-up after THA. The purpose of this study is to identify factors predictive of pain and function five years after THA.

PATIENTS AND METHODS

A multi-center cohort of 7,934 primary unilateral THA patients was prospectively enrolled in Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement (FORCE-TJR). Demographic data, comorbidities, and patient-reported outcome measures (PROMs) were collected pre-operatively and post-operatively at 5 years, including the Hip Injury and Osteoarthritis Outcome Score (HOOS) pain and function in daily living (ADL) scores. Multivariate logistic regression models with 95% confidence interval were used to identify independent predictors of pain and function at 5 years.

RESULTS

The patient dissatisfaction percentage was 8.2% at 5 years after THA. The multivariate regression identified the following predictive factors for the HOOS pain score at 5 years: age, educational level, insurance, smoking, race, Charlson Comorbidity Index (CCI), back pain severity, number of other lower extremity (LE) painful joints, the Knee Injury and Osteoarthritis Outcome Score (KOOS) pain severity of the ipsilateral knee, pre-operative Short-Form Health Survey 36-item (SF-36) mental component score (MCS), and HOOS pain scores. The multivariate regression identified the following predictor factors for HOOS ADL score at 5 years: body mass index, insurance, smoking, race, back pain severity, number of other LE painful joints, KOOS pain severity of ipsilateral knee, pre-op HOOS ADL, and pre-operative SF-36 MCS and SF-36 physical component score (PCS).

CONCLUSION

Overall, 8.2% of patients were dissatisfied five years after primary THA. We have identified a number of factors that predict less improvement in pain and function 5 years after THA. These potentially modifiable factors can be targeted with preoperative patient optimization programs to improve patient outcomes and satisfaction after primary THA. Knowledge of these factors that predict less improvement in pain and function can assist the surgeon and patient during shared decision-making, and in setting appropriate patient expectations pre-operatively.

Patterns and predictors of ten-year mortality after discharge from community-based post-acute care for acquired brain injury: A retrospective cohort study (ABI-RESTaRT), Western Australia, 1991-2017

BACKGROUND

Survivors of acquired brain injury (ABI) are left with long-term disability and an increased risk of mortality years post-injury.

OBJECTIVE

To examine 10-year mortality in adults with ABI after discharge from post-acute care and identify modifiable risk factors to reduce long-term mortality risk.

METHODS

Retrospective cohort study of 586 adults with traumatic (TBI) or non-traumatic brain injury (NTBI), or neurologic condition, consecutively discharged from a post-acute rehabilitation service in Western Australia from 1-Mar-1991 to 31-Dec-2017. Data sources included rehabilitation records, and linked mortality, hospital, and emergency department data. Survival status at 10 years post-discharge was determined. All-cause and cause-specific age- and sex-adjusted standardised mortality ratios (SMR) by ABI diagnosis were calculated using Australian population reference data. Risk factors were examined using multilevel cox proportional hazards regression.

RESULTS

Compared with the Australian population, 10-year all-cause mortality was significantly elevated for all diagnosis cohorts, with the first 12 months the highest risk period. Accidents or intentional self-harm deaths were elevated in TBI (13.2, 95%CI 5.4; 12.1). Neurodegenerative disease deaths were elevated in Neurologic (21.9, 95%CI 13.0; 30.9) and Stroke (19.8; 95%CI 2.4; 27.2) cohorts. Stroke (20.8; 95%CI 7.9; 33.8) and circulatory disease deaths (6.2; 95%CI 2.3; 9.9) were also elevated in Stroke. Psychiatric comorbidity was the strongest risk factor followed by older age, geographical remoteness, and cardiac, vascular, genitourinary and renal comorbidity. Clinically significant improvement in functional independence and psychosocial functioning significantly reduced mortality risk.

CONCLUSIONS

Individuals with ABI have an elevated risk of mortality years post-injury. Comorbidity management, continuity of care, and rehabilitation are important to reduce long-term mortality risk.

Long-term investigation of microplastic abundance in Squalius species in Turkish inland waters

Examining the enduring alterations in microplastic (MP) concentrations within fish in inland waters is of utmost importance in understanding the historical trajectory of plastic waste and formulating consequential predictions regarding upcoming pollution levels. This study includes the collection of fish samples from 22 different river basins in Türkiye and all Squalius species distributed in Türkiye, covering the years 2004-2018, and examined the presence of MP in museum specimens' gastrointestinal tracts (GITs). 331 specimens were examined, and microplastic was observed in 20.8% (69). A mean value of 0.27 ± 0.19 MP per individual was observed, resulting in a cumulative score of 91 MP. Most observed MPs were composed of fiber, representing 79.1% of the total. The polymer types identified were mostly polyethylene (PE) at 38.5% and polyethylene terephthalate (PET) at 29.7%. The black color was prominent among MPs, and MP length ranged between 101 and 4963 μm. The analysis revealed no statistically significant difference in the mean MP values across different years and basins. There is no substantial correlation between the abundance of MP and the sizes of fish, population density, or quantities of plastic production. The data indicate that MP has persistently acted as a contaminant in freshwater ecosystems over an extended period. It is projected that the laundering of synthetic textiles serves as the primary contributor to MP contamination in freshwater bodies. Our results offer significant baseline data on the pervasive issue of MP pollution in the freshwater environment. These findings enable us to gain profound insights into the current state of MP contamination in fish residing in lotic systems while empowering us to make accurate predictions about its future trajectory.

Sex differences in clinical response to deep brain stimulation in resistant obsessive-compulsive disorder

INTRODUCTION

Deep brain stimulation (DBS) is an effective alternative to treat severe refractory obsessive-compulsive disorder (OCD), although little is known on factors predicting response. The objective of this study was to explore potential sex differences in the pattern of response to DBS in OCD patients.

METHODS

We conducted a prospective observational study in 25 patients with severe resistant OCD. Response to treatment was defined as a ≥35% reduction in Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score. Logistic regression models were calculated to measure the likelihood of response at short and long-term follow-up by sex as measured by Y-BOCS score. Similar analyses were carried out to study changes in depressive symptomatology assessed with the Hamilton Depression Rating Scale (HDRS). Additionally, effect sizes were calculated to assess clinical significance.

RESULTS

We did not observe significant clinical differences between men and women prior to DBS implantation, nor in the response after one year of stimulation. At long-term follow-up, 76.9% of men could be considered responders to DBS versus only 33.3% of women. The final response odds ratio in men was 10.05 with significant confidence intervals (88.90-1.14). No other predictors of response were identified. The sex difference in Y-BOCS reduction was clinically significant, with an effect size of 3.2. The main limitation was the small sample size.

CONCLUSIONS

Our results suggest that gender could influence the long-term response to DBS in OCD, a finding that needs to be confirmed in new studies given the paucity of results on predictors of response to DBS.

Long-term outcomes of anterior shoulder instability treated with open latarjet procedure - a systematic review of outcomes at a minimum 15-year follow-up

Background

To systematically review the literature to evaluate the outcomes following an open Latarjet (OL) procedure at a minimum 15-year follow-up.

Methods

Two independent reviewers performed a literature search using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines using 3 databases. Only studies reporting outcomes of OL procedure with a minimum of 15 years of follow-up were included.

Results

Nine studies composed of 326 shoulders (78.2% males) in 313 patients were included (average age 26.9 ± 3.2 years (15-58)), with a mean follow-up of 271.9 ± 69.2 months (180-420) At a minimum 15-year follow-up, 93.5% (286 of 306) patients reported being satisfied with their OL procedure, whilst 86.8% (177 of 204) reported good/excellent outcomes at final follow-up. All nine of the included studies reported an overall rate of recurrent instability was 7.7%, with re-dislocations and subluxation at 3.4% and 5.8%, respectively. The rate of surgical revision was 5.15%; 3.5% of cases were revised for recurrent instability. Instability arthropathy was reported across all included studies as 41.0%.

Conclusion

The OL procedure results in satisfactory clinical outcomes, low rates of recurrent instability and surgical revision at a minimum 15-year follow-up. Although high levels of radiological instability arthropathy and residual pain are found over the same period, these appear stable from a minimum of 10-year follow-up data.

Effects of long-term proton pump inhibitor use on sexual hormones and sexual and reproductive health in female patients

PURPOSE

Proton pump inhibitors (PPIs) are widely used to treat a range of gastrointestinal diseases around the world. Long-term use of PPIs has been associated to a variety of undesirable effects. Although short-term therapy has been shown to have little or no effect on endocrine hormone in women, however, its long-term safety has received little attention. We aimed at evaluating long-term use of PPIs and its effects on female reproductive hormones as well as related clinical consequences.

METHODS

A cross-sectional study was conducted in two outpatient gastroenterology clinics in the province of Khyber Pakhtunkhwa. This study included female patients who had been using PPIs on a regular basis for 3 months or more.

RESULTS

In total of 101 participants, patients with sexual complaints have significantly altered levels of prolactin (p = 0.05), estrogen (p < 0.001) and progesterone (p = 0.001) than patient without sexual complaints. The frequency of amenorrhea (p < 0.001), cyclic disturbances (p < 0.001), breast augmentation (p = 0.001) and painful breast (p = 0.004) were statistically significant in patients with raised serum prolactin values. Serum values of Sex hormone binding globulin SHBG (p < 0.001), estradiol (p = 0.002) and total testosterone (p < 0.001) were significantly altered between normal prolactin and hyperprolactinemic patients.

CONCLUSION

These findings suggest that long-term PPI use may cause endocrine hormone disturbances leading to sexual difficulties in women.

Study on the biological properties of SMILE-derived corneal stromal lenticules after long-term cryopreservation in nutrient capsules

PURPOSE

To investigate the long-term preservation effects of nutrient capsules on the physiological activity, collagen fiber structure and transmittance of corneal stromal lenticules derived from small incision lenticule extraction (SMILE).

METHODS

A new nutrient capsule was constructed for long-term preservation of SMILE-derived corneal stromal lenticules. The lenticules were randomly divided into 99% anhydrous glycerol, and hydrogel nutrient capsules. After preserving for 1 year at -80 °C, lenticules were compared with fresh lenticules. The optical transmittance, tissue morphology, ultrastructure, cells activity and immunogenicity of the lenticules was detected and compared between different groups.

RESULTS

The rate of apoptotic cells was significantly higher in the glycerol group compared with the nutrient capsule group (P < 0.0001). More viable cells were present in the lenticules after nutrient capsule preservation compared to the glycerol group (P = 0.0003). The mean transmittance of the lenticules in the glycerol group (50 ± 18%) was significantly lower (P = 0.0008) compared to the control group (75 ± 11%), and the lenticules transmittance of the nutrient capsule group (64 ± 15%) after long-term preservation was not significantly different (P = 0.23) compared to the control group. The structure of HE staining showed that the collagen fibers in the nutrient capsule group were arranged in parallel and neatly, and a few cavitation vesicles were visible inside the tissue. There was no significant difference in the number of lenticular collagen fibers in the nutritional capsule group compared to the fresh lenticule group (P = 0.06). HLA-DR, HLA-ABC, CD45, CD25 and CD69 expression was low in all groups of lenticules after preservation.

CONCLUSIONS

Nutrient capsules can preserve lenticules for a long time and maintain the transmission structure and cells activity of lenticules.

Prospective, multicenter clinical trial comparing the M6-C compressible cervical disc with anterior cervical discectomy and fusion for the treatment of single-level degenerative cervical radiculopathy: 5-year results of an FDA investigational device exemption study

BACKGROUND CONTEXT

Various total disc replacement (TDR) designs have been compared to anterior cervical discectomy and fusion (ACDF) with favorable short and long-term outcomes in FDA-approved investigational device exemption (IDE) trials. The unique design of M6-C, with a compressible viscoelastic nuclear core and an annular structure, has previously demonstrated favorable clinical outcomes through 24 months.

PURPOSE

To evaluate the long-term safety and effectiveness of the M6-C compressible artificial cervical disc and compare to ACDF at 5 years.

STUDY DESIGN

Prospective, multicenter, concurrently and historically controlled, FDA-approved IDE clinical trial.

PATIENT SAMPLE

Subjects with one-level symptomatic degenerative cervical radiculopathy were enrolled and received M6-C (n=160) or ACDF (n=189) treatment as part of the IDE study. Safety outcomes were evaluated at 5 years for all subjects. The primary effectiveness endpoint was available at 5 years for 113 M6-C subjects and 106 ACDF controls.

OUTCOME MEASURES

The primary endpoint of this analysis was composite clinical success (CCS) at 60 months. Secondary endpoints were function and pain (neck disability index, VAS), physical quality of life (SF-36, SF-12), safety, neurologic, and radiographic assessments.

METHODS

Propensity score subclassification was used to control for selection bias and match baseline covariates of the control group to the M6-C subjects. Sixty-month CCS rates were estimated for each treatment group using a generalized linear model controlling for propensity score.

RESULTS

At 5 years postoperatively, the M6-C treatment resulted in 82.3% CCS while the ACDF group showed 67.0% CCS (superiority p=.013). Secondary endpoints indicated that significantly more M6-C subjects achieved VAS neck and arm pain improvements and showed maintained or improved physical functioning on quality-of-life measures compared to baseline assessments. The M6-C group-maintained flexion-extension motion, with significantly greater increases from baseline disc height and disc angle than observed in the control group. The rates of M6-C subsequent surgical interventions (SSI; 3.1%) and definitely device- or procedure-related serious adverse events (SAE failure; 3.1%) were similar to ACDF rates (SSI=5.3%, SAE failure=4.8%; p>.05 for both).

CONCLUSIONS

Subjects treated with the M6-C artificial disc demonstrated superior 5-year achievement of clinical success when compared to ACDF controls. In addition, significantly more subjects in the M6-C group showed improved pain and physical functioning scores than observed in ACDF subjects, with no difference in reoperation rates or safety outcomes.

Specialist treatment for persistent depression in secondary care: Sustained effects from a multicentre UK study at 24 and 36 months

BACKGROUND

Despite the known health costs of persistent depression, there is no established service framework for the treatment of this disorder and a lack of long-term outcome data to inform commissioning. To address this gap, we report the long-term clinical effectiveness of a randomised controlled trial (RCT) testing a specialist, collaborative model of care for people with persistent moderate to severe unipolar depression.

METHODS

A multicentre, pragmatic, single-blind, parallel-group randomised controlled trial comparing outcomes from a Specialist Depression Service (SDS) offering collaborative treatment with cognitive behavioural therapy (CBT) and pharmacotherapy for 12 months with treatment as usual (TAU) for persistent, moderate-severe depression in UK secondary care. Participants were initially assessed at baseline, 3, 6, 9, 12, and 18 months, with primary endpoints (17-item Hamilton Depression Rating Scale [HDRS17], and a Global Assessment of Functioning [GAF]) reported elsewhere (Morriss et al., 2016). Additional long-term, post-treatment, follow-up was made at 24 and 36 months with outcomes presented here.

CLINICALTRIALS

gov (NCT01047124) and ISRCTN registration (ISRCTN 10963342).

RESULTS

At 24 months there remained a statistically significant between-group difference in HDRS17-2.69 (-5.14, -0.23) and a non-significant improvement in GAF 2.85 (-1.23, 6.94), both favouring the SDS. Simple statistics are presented at 36 months, due to attrition, showing higher continued response and remission vs TAU across all measures.

LIMITATIONS

Potential bias through loss to follow-up, particularly beyond 24 months.

CONCLUSIONS

Compared with standard secondary care, SDS management of persistent moderate-severe depression, produced long-term clinical benefits, sustained following treatment completion, suggesting a model for future specialist care.

Long-term survivability of surgical and nonsurgical management of spinal epidural abscess

BACKGROUND CONTEXT

Spinal epidural abscess (SEA) is a rare and life-threatening infection within the epidural space with significant functional impairment and morbidity. Active debate remains over whether to operate for SEAs, with limited existing data comparing the long-term survivability after surgical versus nonsurgical management.

PURPOSE

This study aims to determine the long-term survival of patients who underwent surgical and nonsurgical management for SEA.

STUDY DESIGN

Retrospective cohort study.

PATIENT SAMPLE

A total of 250 consecutive SEA patients.

OUTCOME MEASURES

Survival and mortality rates, complications.

METHODS

All patients treated at a tertiary medical center for a primary SEA from January 2000 to June 2020 are identified. Data collection is by retrospective chart review. Cox proportional hazards regression models are used for all survival analyses while controlling for potential confounding variables and with multiple testing corrections.

RESULTS

A total of 35 out of 250 patients died with an overall all-cause mortality of 14%. More than half of all deaths occurred within 90 days after treatment. The 90-day, 3-year, and 5-year survival rates are 92.8%, 89.2%, and 86.4%, respectively. Among surgery patients, the all-cause mortality was 13.07%, compared to 16.22% for medically-managed patients. Surgical treatment (decompression, fusion, debridement) significantly reduced the risk of death by 62.4% compared to medical therapy (p=.03), but surgery patients experienced a significantly longer mean length of stay (p=.01). Risk factors of short-term mortality included hypoalbuminemia (<3.5 g/dL), American Society of Anesthesiologists (ASA) 4+, and cardiac arrest. Risk factors of long-term mortality were immunocompromised state, elevated WBC count >12,000, sepsis, septic shock, ASA 4+, and cardiac arrest (p<.05). In terms of complications, surgically-managed patients experienced a higher proportion of deep vein thrombosis (p<.05).

CONCLUSIONS

The overall long-term survivability of SEA treatment is relatively high at (86% at 5-year) in this study. The following SEA mortality risk factors were identified: hypoalbuminemia (short-term), immunocompromised state (long-term), leukocytosis (long-term), sepsis and septic shock (long-term), ASA 4+ and cardiac arrest (overall). For primary SEA patients, surgical management may reduce mortality risk compared to nonsurgical management.

A mixed-studies systematic review of self-administered music interventions (SAMIs) for psychological wellbeing in people with chronic health conditions: Meta-analysis and narrative summary

OBJECTIVE

This mixed-studies systematic review examined how self-administered music interventions (SAMIs) influenced psychological wellbeing for people with chronic health conditions.

METHODS

We searched 7 databases and performed citation and reference checks to find studies that implemented SAMIs for psychological outcomes in adults with chronic health conditions published between January 1990 and March 2023. Risk of bias was assessed using Downs and Black's quality assessment checklist criteria. Data were synthesised using meta-analysis and narrative summary.

RESULTS

We included 21 articles (934 participants). Meta-analyses demonstrated significant effects of SAMIs on outcomes measuring post-test (SMD = 0.72) and long-term depression (SMD = 0.51), post-test generic (SMD = 0.55) and disease-specific (SMD = 0.56) psychological quality of life, and post-test mood disturbance (SMD = 0.64). A small effect suggested that SAMIs with multiple in-person sessions guided by a music therapist may reduce anxiety (SMD = 0.37) CONCLUSION: SAMIs may improve psychological wellbeing in people with chronic health conditions. Long-term benefits of SAMIs have been recognised for the depression outcome.

PRACTICE IMPLICATIONS

Encouraging people with chronic health conditions to self-administer music interventions may provide benefits to their psychological wellbeing.

Trajectories of social function in patients with first-episode schizophrenia: Analysis of data from a 10-year follow-up study

BACKGROUND

Patients with schizophrenia may have diverse functional outcomes. However, the long-term functional trajectories of patients with first-episode schizophrenia (FES) are unclear.

METHODS

We extracted data from the Chinese First-Episode Schizophrenia Trial, a 10-year prospective study of antipsychotic-naïve patients with FES. We applied K means cluster modelling to longitudinal data on the social function of patients with FES and examined associations of the empirically derived trajectories with baseline clinical characteristics of the 10-year follow-up.

OUTCOMES

Three distinct functional trajectories emerged: improving-favorable (39·3%), improving-poor (17·8%) and improving-stable (42·9%). All three trajectories demonstrated Personal and Social Performance (PSP) score improvement in the first six months. The improving-poor trajectory demonstrated PSP score decline during the second six months and thereafter, while PSP scores in the other two trajectories were mainly stable during the same period. Patients in the improving-favorable trajectory had higher baseline PSP scores than those in the improving-poor trajectory (OR=0·904 [0·852, 0·961], p < 0·05) and the improving-stable trajectory (OR=0·870 [0·825, 0·918], p < 0·001) and were more likely to be female than those in the improving-stable trajectory (OR=2·699 [1·030, 7·074], p < 0·05).

CONCLUSIONS

Patients with FES demonstrated varied long-term functional recovery profiles. The first year, especially the second half of the first year, is a key period for social function interventions that improve long-term functional outcomes. Male patients and patients with poor baseline function may particularly benefit from such interventions.

Long-Term Control of Nasal Tip Position: Quantitative Assessment of Caudal Septal Extension Graft

BACKGROUND

Control of nasal tip position is critical to final rhinoplasty outcomes. Two frequent methods of exerting tip control are columellar strut and caudal septal extension graft (SEG). Past work has demonstrated that SEG are better able to preserve tip position. However, there is no quantitative data describing long-term projection and rotation. The purpose of this study was to analyze long-term maintenance of tip projection and rotation following SEG.

METHODS

A retrospective study of adult patients undergoing open rhinoplasty was conducted. Three-dimensional photogrammetric evaluation of nasal tip position was performed. Anthropometric points were analyzed preoperatively and postoperatively. Outcome variables were tip projection, tip rotation, and nasal length.

RESULTS

Twenty patients were included with an average follow-up time of 3.3 years (2.0 - 6.6 years). From postoperative week 1 to 6, there was a statistically significant decrease in rotation (-4.3%, p<0.01). There were no statistically significant decreases in projection, rotation, or nasal length from 6 weeks postoperative to 2 years postoperative, or from 6 weeks postoperative to final follow-up (2.0 - 6.6 years).

CONCLUSIONS

Nasal tip projection and rotation appear to decrease from the immediate postoperative position, likely due to resolving edema. In this study, patients that underwent open rhinoplasty with SEG experienced modest loss of projection and rotation until 6 weeks postoperative, but projection and rotation were maintained from 6 weeks postoperative to 2 years and beyond.

Clinical and radiological outcomes of an uncemented metaphyseal short stem at minimum 10 years of follow-up: a prospective observational study

PURPOSE

There is growing interest around short stems as they provide a less invasive approach for total hip arthroplasty preserving bone stock for a possible revision surgery if required. The main purpose of this work was to assess the long-term performance of an uncemented metaphyseal short stem in terms of survival rate and in addition its clinical and radiological outcomes.

MATERIALS AND METHODS

From January to December 2010, we prospectively enrolled all consecutive patients undergoing primary total hip arthroplasty with an uncemented metaphyseal short stem in our institution with a minimum follow-up of 10 years. The radiographic features investigated were the varus-valgus stem orientation, areas of osteolysis and radiolucencies, stress shielding, and heterotopic calcifications. The clinical outcomes were measured using the HHS.

RESULTS

A total of 163 patients (172 hips) were finally included and the measured survival rate at 10 years was 99.6%. The average HHS increased from 55.0 preoperatively to 97.8 at the last follow-up (p < 0.0001). Among them, 137 patients (164 hips) were also available for radiographic assessment. Mild varus malalignment was observed in 40% of cases and remained stable in the serial X-rays and was not associated with step loosening. Mild stress shielding was observed around 13 stems (9%) and moderate only around 3 implants.

CONCLUSION

In conclusion, the uncemented metaphyseal short stems showed excellent survival and clinical results at 10 years and at a radiographical level very low stress shielding was observed; moreover, besides the high frequency of varus alignment the implanted stems was not associated with revision surgery or with worse clinical outcomes.

One-Year Consistent Safety, Utilization, and Efficacy Assessment of Remote Electrical Neuromodulation (REN) for Migraine Treatment

INTRODUCTION

Migraine is a chronic neurological disorder causing severe pain and disability in more than a billion people worldwide. Ideal treatment should provide long-term efficacy with minimal side effects. Previous studies indicate that remote electrical neuromodulation (REN) is an efficacious and safe treatment option for the acute treatment of migraine in clinical practice. This study examined long-term safety, utilization, and efficacy of REN during 12 consecutive usage months.

METHODS

Data from patients with migraine across the USA using REN to treat their migraine attacks were electronically collected from the Nerivio® device. All patients who used REN during 12 consecutive months were included, and data were compared across months. Safety was assessed by the number and type of adverse events. Utilization was measured by the number of monthly treatments. Efficacy was evaluated as consistent change in headache pain intensity, functional disability, and disappearance of associated symptoms from baseline to 2 h post treatment.

RESULTS

Data were analyzed from 409 people living with migraine who treated with REN for 12 consecutive months, performing a total of 39,531 treatments. The incidence of device-related adverse events (dAEs) was 1.96% (8/409), including two negligible (0.49%), five mild (1.22%), one moderate (0.24%), and no severe events. All patients continued treatment with REN despite dAEs. One-year average monthly utilization was 8.05 treatments (SD 1.15). Month-to-month utilization did not change during 12 months of consecutive use [F(4.895, 1997.204) = 2.014, p = 0.075, repeated-measures ANOVA]. One-year average efficacy showed 74.1% of users reported consistent 2-h pain relief, and 26.0% reported consistent pain freedom. Month-to-month pain relief and pain freedom did not change during 12 months of consecutive use [F(11, 1069) = 0.55, p = 0.873 and F(11, 1295) = 0.69, p = 0.750 respectively; generalized linear mixed model analysis].

CONCLUSION

REN is a safe and well-tolerated acute migraine treatment, with stable efficacy and utilization over 1 year, making it an advantageous non-drug option for the long-term management of this chronic disease.

Long-term changes in bone mineral density following adolescent idiopathic scoliosis surgery: a minimum 34-year follow-up

PURPOSE

To investigate longitudinal changes in bone mineral density (BMD) in middle-aged female patients who underwent spinal fusion for adolescent idiopathic scoliosis (AIS).

METHODS

The study subjects were 229 female patients who were diagnosed with AIS and underwent spinal fusion between 1968 and 1988. A two-step survey study was conducted on 19 female AIS patients. BMD, Z-scores, T-scores, and the prevalence of osteoporosis and osteopenia were compared between the initial (2014-2016) and second (2022) surveys. Correlations between the annual changes in Z-scores and T-scores with radiographic parameters, body mass index (BMI), and the number of remaining mobile discs were analyzed.

RESULTS

BMD decreased significantly from the initial (0.802 ± 0.120 g/cm2) to the second survey (0.631 ± 0.101 g/cm2; p < 0.001). Z-scores decreased from 0.12 ± 1.09 to - 0.14 ± 1.04, while T-scores decreased significantly from - 0.70 ± 1.07 to - 1.77 ± 1.11 (p < 0.001). The prevalence of osteopenia and osteoporosis increased significantly from 36.8% to 89.5% (p = 0.002), but the increase in osteoporosis alone was not statistically significant (5.3% to 26.3%; p = 0.180). Moderate negative correlations were found between annual changes in Z-scores and both main thoracic (MT) curve (r = - 0.539; p = 0.017) and lumbar curve (r = - 0.410; p = 0.081). The annual change in T-scores showed a moderate negative correlation with the MT curve (r = - 0.411; p = 0.081).

CONCLUSION

Significant reductions in BMD and an increased prevalence of osteopenia and osteoporosis were observed in middle-aged female AIS patients who had undergone spinal fusion. The decline in Z-scores in patients with AIS suggested that there was an accelerated loss of BMD compared with the general population. Larger residual curves could pose an added osteoporosis risk. Further research is needed to understand if the onset of osteoporosis in AIS patients is attributable to the condition itself or the surgical intervention.

What to Expect on the Long-term Follow-up of Pediatric Pyeloplasty: Critical Time Intervals and Risk Factors

BACKGROUND

Standard protocol for post-pyeloplasty monitoring in children and natural course of hydronephrosis resolution have not been well defined. We aimed to analyze critical time intervals and risk factors in the long-term clinical outcomes of children who were operated for ureteropelvic junction obstruction.

METHODS

Files of patients who underwent open dismembered pyeloplasty between January 2000 and December 2012 and had a ≥10 years follow-up were retrospectively reviewed. Changes in SFU hydronephrosis grade, pelvis anteroposterior diameter (APD), renal parenchymal thickness, split renal functions (SRF) on MAG-3 scan as well as development of hypertension and proteinuria were noted. Complete resolution was defined as SFU grade 0-1 or APD≤10 mm or ≥50 % APD decrease.

RESULTS

Overall, 223 patients (161 boys, 72.1 %) with a median age of 9 (range 1-185) months underwent unilateral pyeloplasty, whereas 14 patients (13 boys, 92.8 %) with a median age of 4 (range 2-39) months underwent bilateral pyeloplasty. Median follow-up was 13 (range 10-22) years. Complete resolution was observed in 190 patients (85.2 %). None of the cases required re-do pyeloplasty. Regarding unilateral cases, postoperative changes in hydronephrosis reached a plateau at the 60th month. Also, there was no significant difference regarding SRF between the 12th month and the 60th month (p > 0.05). Hypertension developed after a median period of 12 years in 13 (5.4 %) of the patients, while proteinuria developed in four (1.6 %) patients. Bilateral disease (HR: 2.518, p = 0.034) was found to be a significant determinant for development of hypertension and/or proteinuria.

CONCLUSIONS

Our results indicated that ultrasonographic findings stabilized after the 60th month postoperatively, and SRF remained stable between the postoperative 12th and the 60th months. The risk of developing hypertension and/or proteinuria was 2.5 times greater in bilateral cases.

Intravitreal Conbercept

PURPOSE

To compare long-term real-world outcomes of corneal thickness (CT) alterations in proliferative diabetic retinopathy (PDR) patients treated with panretinal photocoagulation (PRP) and intravitreal conbercept (IVC).

METHODS

This retrospective study included 69 eyes of 69 patients with PDR (42 PRP and 27 IVC). Full corneal thickness (FCT), corneal epithelial thickness (CET) and corneal stromal thickness (CST) measured by anterior segment optical coherence tomography at baseline were compared between groups. These CT changes at last follow-up from baseline were also compared between groups and within each group.

RESULTS

During a mean follow-up of more than two years, the IVC group demonstrated a significantly increased corneal thickness from baseline compared to the PRP group in some areas (PRP vs. IVC: FCT 0-2 mm: -0.59 ± 9.31 vs. 5.59 ± 9.23 μm, p = 0.009; CST 0-2 mm: -2.05 ± 8.79 vs. 3.48 ± 7.52 μm, p = 0.015; CST 2-5 mm: -1.78 ± 13.27 vs. 5.68 ± 14.53 μm, p = 0.046). In within-group comparisons, a significantly increased FCT from baseline was found in the 0-2 mm area in the IVC group (p = 0.004), but no significant change was observed in the PRP group (p = 0.691). For CET changes, a significantly increased CT was observed in the 0-2 mm, 2-5 mm and 5-7 mm areas in both groups respectively (all p < 0.05). Regarding CST, an increased CT was found in the 0-2 mm area in the IVC group (p = 0.037), while a decreased trend was observed in 0-2 mm and 2-5 mm areas in the PRP group (all p > 0.05).

CONCLUSION

When using PRP or IVC in the long-term management of PDR, CT changes should be considered. This may provide evidence for corneal protection during PDR treatment.

Long-Term Disability Outcomes for Migrants (and Non-migrants) 12 Years Post-injury: Results from the Prospective Outcomes of Injury Study in New Zealand

To understand, and identify predictors of, long-term post-injury (i.e. 12 years post-injury) disability outcomes for migrants and non-migrants. This 12-year longitudinal study followed participants with entitlement claim injuries registered with New Zealand's universal no-fault injury insurer between 2007 and 2009. Information was collected about migrant status, other sociodemographic, health and disability characteristics, and injury characteristics. Disability outcome information was collected 12 years later. Of 1543 people interviewed 12 years post-injury, 1497 had disability and migrant status data available; 20% were migrants (n = 301). Migrants reporting inadequate pre-injury household income or those who perceived their injury as a threat to life at the time of injury were more likely to experience disability 12 years post-injury (aRR 2.08; 95% CI 1.09-4.03, aRR 2.93; 95%CI 1.17-6.69, respectively). Hospitalised injured migrants were significantly less likely to have long-term disability (aRR 0.18; 95%CI 0.04-0.55) than those not hospitalised. We found sociodemographic and injury-related characteristics were independently associated with long-term disability among migrants. We highlight that some characteristics, ascertained early in the injury pathway, predict risk of long-term disability. Early post-injury interventions focused on improving disability outcomes for migrants may also have long-term impacts.

Long-term outcome after implementation of endovascular-first strategy to treat acute mesenteric ischemia

OBJECTIVE

To evaluate the rationale of an aggressive endovascular-first strategy to treat elderly patients with acute mesenteric ischemia (AMI) by studying long-term survival, readmissions, and patients' discharge to home vs nursing facility a decade after an episode of AMI.

METHODS

The retrospective study cohort included 66 consecutive patients (all-comers) treated for arterial occlusive AMI between 2009 and 2013. Endovascular revascularization (EVR) was attempted in 50 patients (EVR+), whereas 16 patients were treated without attempted revascularization (EVR-). All patients were followed until death or September 2022. Studied outcomes included discharge status, long-term survival and cause of death and readmissions related to AMI.

RESULTS

The mean age of all 66 patients was 78 ± 10 years: 79 ± 9 years in the EVR+ group and 76 ± 12 years in the EVR- group. EVR was technically successful in 44 patients (88%); three patients underwent subsequent open revascularization after EVR failure. One-third required bowel resection after EVR. The 30-day mortality for all patients was 44%; 32% in the EVR+ group and 81% in the EVR- group. Only two survivors were permanently institutionalized, whereas all others were discharged to the same place they lived prior to the AMI episode. There were four AMI-related readmissions during the follow-up; all were in the EVR+ group. Two patients underwent reinterventions for recurrent AMI. One-year survival was 52% for EVR+ and 19% for EVR- patients. Five-year survival rates were 18% and 13%, respectively. The causes of deaths were mesenteric ischemia in 22, other cardiovascular event in 21, and non-cardiovascular cause in 19 patients. Four patients were alive at the end of the follow-up.

CONCLUSIONS

In this unselected elderly population with AMI, the aggressive strategy to attempt EVR resulted in a high revascularization rate and favorable outcomes. The high proportion of patients returning to their prior living status and low readmission rate after survival from AMI encourages active treatment of high-functioning elderly patients.

Image-based robotic-arm assisted unicompartmental knee arthroplasty provides high survival and good-to-excellent clinical outcomes at minimum 10 years follow-up

PURPOSE

The purpose of the present study was to determine the incidence of revision and report on clinical outcomes at a minimum of 10 years follow-up in patients who had received a medial unicompartmental knee arthroplasty (UKA) with an three-dimensional image-based robotic system.

METHODS

A total of 239 patients (247 knees), who underwent medial robotic-arm assisted (RA)-UKA at a single center between April 2011 and June 2013, were assessed. The mean age at surgery was 67.0 years (SD 8.4). Post-operatively, patients were administered the Forgotten Joint Score-12 (FJS-12) and asked about their satisfaction (from 1 to 5). Post-operative complications were recorded. Failure mechanisms, revisions and reoperations were collected. Kaplan-Meier survival curves were calculated, considering revision as the event of interest.

RESULTS

A total of 188 patients (196 knees) were assessed at a mean follow-up of 11.1 years (SD 0.5, range 10.0-11.9), resulting in a 79.4% follow-up rate. Seven RA-UKA underwent revision, resulting in a survivorship rate of 96.4% (CI 94.6%-99.2%). Causes of revision included aseptic loosening (2 cases), infection (1 case), post-traumatic (1 case), and unexplained pain (3 cases). The mean FJS-12 and satisfaction were 82.2 (SD 23.9) and 4.4 (SD 0.9), respectively. Majority of cases (174/196, 88.8%) attained the Patient Acceptable Symptoms State (PASS, FJS-12 > 40.63). Male subjects had a higher probability of attaining a "forgotten joint" (p < 0.001) and high satisfaction (equal to 5, p < 0.05), when compared to females.

CONCLUSIONS

Three-dimensional image-based RA-UKA demonstrated high implant survivorship and good-to-excellent clinical outcomes at minimum 10 years follow-up. Pain of unknown origin represented the most common reason for RA-UKA revision.

Benefits of lumbar spine fusion surgery reach 10 years with various surgical indications

Background Context

Lumbar spine fusion (LSF) surgery is a viable form of treatment for several spinal disorders. Treatment effects are preferably to be endorsed in real-life settings.

Methods

This prospective study evaluated the 10-year outcomes of LSF. A population-based series of elective LSFs performed at 2 spine centers between January 2008 and June 2012 were enrolled. Surgeries for tumor, acute fracture, or infection, neuromuscular scoliosis, or postoperative conditions were excluded. The following patient-reported outcome measures (PROMs) were collected at baseline, and 1, 2, 5, and 10 years postsurgery: VAS for back and leg pain, ODI, SF-36. Longitudinal measures of PROMs were analyzed using mixed-effects models.

Results

A total of 683 patients met the inclusion criteria, and 630 (92%) of them completed baseline and at least 1 follow-up PROMs, and they constituted the study population. Mean age was 61 (SD 12) years, 69% women. According to surgical indication, patients were stratified into degenerative spondylolisthesis (DS, n=332, 53%), spinal stenosis (SS, n=102, 16%), isthmic spondylolisthesis (IS, n=97, 15%), degenerative disc disease (DDD, n=52, 8%), and deformity (DF, n=47, 7%).All diagnostic cohorts demonstrated significant improvement at 1 year, followed by a partial loss of benefits by 10 years. ODI baselines and changes at 1 and 10 years were: (DS) 45, -21, and -14; (SS) 51, -24, and -13; (IS) 41, -24, and -20; (DDD) 50, -20, and -20; and (DF) 50, -21, and -16, respectively. Comparable patterns were seen in pain scores. Significant HRQoL achievements were recorded in all cohorts, greatest in physical domains, but also substantial in mental aspects of HRQoL.

Conclusions

Benefits of LSF were partially lost but still meaningful at 10 years of surgery. Long-term benefits seemed milder with degenerative conditions, reflecting the progress of the ongoing spinal degeneration. Benefits were most overt in pain and physical function measures.

The Efficacy and Safety of Laparoscopic Single-Anastomosis Duodeno-ileostomy with Sleeve Gastrectomy (SADI-S) in Mid- and Long-Term Follow-Up: a Systematic Review

This systematic review of 10 studies aimed to investigate the mid- and long-term results of duodeno-ileostomy with sleeve gastrectomy (SADI-S) according to the PRISMA guideline. Related articles, which reported outcomes of laparoscopic SADI-S with follow-up ≥ 3 years, were selected and analyzed. The percentage of excess weight loss (EWL) was 70.9-88.7%, and 80.4% at 6, and 10 years, respectively. The more common late complications were malabsorption (6.3%) and gastroesophageal reflux disease (GERD) (3.6%). The remission rates of hypertension, diabetes, GERD, obstructive sleep apnea, and dyslipidemia were 62.9%, 81.3%, 53.2%, 60.9%, and 69.7%, respectively. In conclusion, SADI-S is a safe and effective surgical technique with durable weight loss and a high rate of comorbidity resolution in mid and long term.

Long-term adherence to pessary use in women with pelvic organ prolapse: A retrospective cohort study

PURPOSE OF THE RESEARCH

Vaginal pessary use is an established, non-surgical treatment option for pelvic organ prolapse. While satisfaction rates are initially high, they seem to decline over time. We aimed to determine the median duration of pessary use among our patients and to evaluate reasons for discontinuation.

METHODS

All patients who were treated with a vaginal pessary for pelvic organ prolapse between 2007 and 2022 at our institution (a maximum observation period of 15 years) were included in this retrospective cohort study. Data were collected from the in-house electronic databases and the date of pelvic floor surgery was defined as the primary endpoint. In case of no documented surgery, the date of the last follow-up visit (for patients lost to follow-up or who discontinued pessary use without subsequent surgery) or the date of final data collection (for those with presumed continued pessary use) was used as the primary endpoint. Duration of pessary use is represented by Kaplan-Meier curves. Effects of possible confounders were investigated by Cox regression models. A Cox regression model was evaluated for patients with the three most common types of pessary: ring, cube and shell. A chi-square test was performed to compare therapy adherence according to pessary type.

PRINCIPAL RESULTS

Data of 779 patients could be included in the statistical analysis. The estimated median duration of pessary use was 173 weeks (95 % CI 104-473) - approximately 3.3 years. Overall, 30 % of patients opted for surgical therapy and the majority of them did so within 4 months of initiation of pessary use (median time: 19 weeks, 95 % CI 16-26). In 5 % of cases a discontinuation of pessary use without subsequent surgery was documented and 18 % were lost to follow-up before a planned visit, thus leaving 47 % of our patients with presumed continued pessary use. Possible confounding factors for discontinuation of pessary use were tested but were found to be non-significant (body mass index, Pelvic Organ Prolapse - Quantification score, pelvic floor training, age, parity, menopausal status, nicotine consumption, incontinence or size of pessary). Reasons for discontinuation of pessary use were documented in 51 % of patients: unspecified patient wish (23 %), pessary use tiredness (10 %), general dissatisfaction with pessary therapy (7 %), unspecified reasons (5 %), pessary self-change not possible (1 %), erosion, bleeding, pain (2 %); none of the pessary types fitted (2 %).

CONCLUSIONS

According to our data, almost half of our patients with pelvic organ prolapse and pessary therapy continued pessary use until a maximum follow-up time of 15 years, whereas about one-third of patients finally opted for surgical repair (a majority of these within 4 months after pessary therapy initiation). The remaining patients were either lost to follow-up or discontinued pessary use without subsequent surgery. The stated reasons for discontinuation of pessary use were mostly non-specific, but only 1 % reported that pessary self-change was not possible. Erosion bleeding or pain was documented in only 2 % of cases as reason for discontinuation. This information helps clinicians to inform their patients with pelvic organ prolapse about expected pessary therapy success and strengthens individual counselling. Furthermore, our data indicates vaginal pessary use for pelvic organ prolapse is feasible and safe for all women and that therapy adherence can extend beyond 5 years.

Twenty-year survivorship cohort study of total knee arthroplasty in Asian patient using a single posterior-stabilized implant performed by a single surgeon

INTRODUCTION

As life expectancy has improved, the potential number of revision candidates is also expected to increase among patients who have undergone a total knee arthroplasty (TKA). The longevity of modern posterior stabilized knee prostheses after 20 years of use has not been well documented, especially in Asian populations that require a deeper flexion range due to a floor-based lifestyle.

HYPOTHESIS

Firstly, the implant longevity regarding mechanical failures such as aseptic loosening and polyethylene (PE) wear would vary over a longer follow-up depending on the age groups; and secondly there would be unique risk factors for revision surgery in an Asian TKA cohort.

MATERIAL AND METHODS

We conducted this age-stratified survival analysis in a consecutive series of 368 NexGen Legacy Posterior Stabilized (LPS) TKAs performed by a single surgeon. These cases were divided into four age groups (< 60 years, early 60s, late 60s, and ≥ 70 years). The implant longevity against aseptic mechanical failures was calculated using the Kaplan-Meier method. The revision surgery risk was evaluated using postoperative factors including a deep flexion capability (> 135̊), and postoperative mechanical alignments.

RESULTS

Overall survivorship was significantly lower in the youngest groups than other groups (Log-rank test, p=0.001). The cumulative 20-year implant longevity was more than 95% in the two oldest groups, but less than 60% in the youngest group. It was notable that the post-TKA implant longevity was not apparent up to 10 years between the age groups (p=0.073∼0.458). Aseptic loosening was observed with an earlier onset (3.1 to 18.9 years) trend than PE wear (9.8∼17.9 years), with most cases arising in the youngest groups. Flexion limitation and varus alignment were significant risks to aseptic loosening and PE wear (Cox proportional hazard regression: p=0.001 and 0.045, respectively).

DISCUSSION

A younger age (< 60 years), inability of postoperative deep flexion, and varus alignment were significant risk factors for aseptic loosening and PE wear after modern PS design in this Asian cohort. The difference in postoperative longevity affected by these factors was not obvious during the first 10 years but emerged over a second decade.

Survival and complication rates of two dental implant systems supporting fixed restorations: 10-year data of a randomized controlled clinical study

OBJECTIVES

To compare clinical, radiographic, biological and technical long-term outcomes of two types of dental implants over a period of 10 years.

MATERIALS AND METHODS

Ninety-eight implants were placed in 64 patients, randomly allocated to one of two manufacturers (AST and STM). All implants were loaded with fixed restorations. Outcome measures were assessed at implant insertion (Ti), at baseline examination (TL), at 1, 3, 5, 8 and 10 (T10) years. Data analysis included survival, bone level changes, complications and clinical measures.

RESULTS

Re-examination was performed in 43 patients (23 AST and 20 STM) at 10 years. The implant level analysis was based on 37 (AST) and 32 (STM) implants. Survival rates of 100% were obtained for both groups. The median changes of the marginal bone levels between baseline and T10 (the primary endpoint) amounted to a loss of 0.07 mm for group AST and a gain of 0.37 mm for group STM (intergroup p = 0.008). Technical complications occurred in 27.0% of the implants in group AST and in 15.6% in group STM. The prevalence of peri-implant mucositis was 29.7% (AST) and 50.1% (STM). The prevalence of peri-implantitis amounted to 0% (AST) and 6.3% (STM).

CONCLUSIONS

Irrespective of the implant system used, the survival rates after 10 years were high. Minimal bone level changes were observed, statistically significant but clinically negligible in favor of STM. Technical complications were more frequently encountered in group AST, while group STM had a higher prevalence of peri-implant mucositis.

Prospective evaluation of clinical and radiographic 10-year results of Fitmore short-stem total hip arthroplasty

BACKGROUND

Short stems were introduced into total hip arthroplasty (THA) to preserve bone stock, to transmit more load to the proximal femur, and to enable minimal invasive approaches. This study is the first long-term study (with a follow-up of 10 years) of the survival as well as the clinical and radiographic outcomes of the Fitmore hip stem, a short curved uncemented stem.

METHODS

In total, 123 Fitmore hip stems were prospectively evaluated. At the final 10-year follow-up, 80 Fitmore stems (78 patients: 30 female, 48 male) were eligible for evaluation. Clinical parameters were thigh pain, EQ-5D, Harris Hip Score (HHS) and Oxford Hip Score. Radiographic parameters were cortical hypertrophy (CH), bone condensation, cortical thinning, radiolucency, reactive lines, calcar rounding, calcar resorption, subsidence and varus/valgus position.

RESULTS

After 10 years, there was a survival rate of 99% (1 revision because of aseptic stem loosening). HHS had improved from 59 to 94 and Oxford Hip Score from 22 to 43. CH rate after 1 year was 69% and after 10 years 74%. In the first year, radiolucency was found in 58% and in 17.5% after 10 years. Subsidence after 1 year was 1.6 ± 1.6 mm and 5.0 ± 3.1 mm after 10 years.

CONCLUSIONS

The Fitmore hip stem showed a survival rate of 99% as well as good clinical and radiographic outcomes in the long-term follow-up of 10 years.

Residential greenness alleviated the adverse associations of long-term exposure to ambient PM1 with cardiac conduction abnormalities in rural adults

BACKGROUND

Ambient air pollution was linked to elevated risks of adverse cardiovascular events, and alterations in electrophysiological properties of the heart might be potential pathways. However, there is still lacking research exploring the associations between PM1 exposure and cardiac conduction parameters. Additionally, the interactive effects of PM1 and residential greenness on cardiac conduction parameters in resource-limited areas remain unknown.

METHODS

A total of 27483 individuals were enrolled from the Henan Rural Cohort study. Cardiac conduction parameters were tested by 12-lead electrocardiograms. Concentrations of PM1 were evaluated by satellite-based spatiotemporal models. Levels of residential greenness were assessed using Enhanced Vegetation Index (EVI) and Normalized difference vegetation index (NDVI). Logistic regression models and restricted cubic splines were fitted to explore the associations of PM1 and residential greenness exposure with cardiac conduction abnormalities risk, and the interaction plot method was performed to visualize their interaction effects.

RESULTS

The 3-year median concentration of PM1 was 56.47 (2.55) μg/m3, the adjusted odds rate (ORs) and 95% confidence intervals (CIs) for abnormal HR, PR, QRS, and QTc interval risk in response to 1 μg/m3 increase in PM1 were 1.064 (1.044, 1.085), 1.037 (1.002, 1.074), 1.061 (1.044, 1.077) and 1.046 (1.028, 1.065), respectively. Participants exposure to higher levels of PM1 had increased risks of abnormal HR (OR = 1.221, 95%CI: 1.144, 1.303), PR (OR = 1.061, 95%CI: 0.940, 1.196), QRS (OR = 1.225, 95%CI: 1.161, 1.294) and QTc interval (OR = 1.193, 95%CI: 1.121, 1.271) compared with lower levels of PM1. Negative interactive effects of exposure to PM1 and residential greenness on abnormal HR, QRS, and QTc intervals were observed (Pfor interaction < 0.05).

CONCLUSION

Long-term PM1 exposure was associated with elevated cardiac conduction abnormalities risks, and this adverse association might be mitigated by residential greenness to some extent. These findings emphasize that controlling PM1 pollution and increasing greenness levels might be effective strategies to reduce cardiovascular disease burdens in resource-limited areas.

"What will the doctor give me, the same painkiller?": a qualitative study exploring health-care seeking and symptoms self-management among patients for the treatment of long-term chikungunya disease, in Curaçao

BACKGROUND

Long-term chikungunya disease, characterized by persistent disabling rheumatic symptoms, including poly-arthralgia/arthritis of severe pain intensity, can persist for years after infection with the re-emerging mosquito-borne chikungunya virus. Although persistent symptoms and pain severity are important determinants of health-care seeking and self-management of symptoms, research on these in relation to long-term chikungunya disease is scarce. This study aimed to explore the perceived benefits and perceived barriers concerning health-care seeking, based on the Health Belief Model, and the symptoms self-management strategies used for health outcome improvement among individuals affected by long-term chikungunya disease.

METHODS

An exploratory qualitative descriptive study was conducted with 20 purposively selected adults (17 females and 3 males) with persistent rheumatic symptoms, recruited from an ongoing longitudinal chikungunya cohort, in Curaçao. Semi-structured interviews were carried out, audio-recorded, and transcribed. An iterative coding process was used for themes identification through inductive thematic analyses.

RESULTS

No perceived benefits in health-care seeking were reported. Identified themes in relation to perceived barriers were: (1) health-care seeking at disease onset; (2) general practitioners (GPs) perceptions and awareness of persistent symptoms; (3) challenges for medical referrals and support; (4) no validation of symptoms and challenges accessing therapy; (5) health system restrictions; and (6) social stigmatization of psychological help. These perceived barriers have led participants to self-manage persistent symptoms. Over-the-counter pharmacological and/or non-pharmacological treatments were used without consulting GPs. Identified themes were: (1) self-medication of symptoms; and (2) self-management true non-pharmacological treatments.

CONCLUSIONS

To promote the benefits of long-term health-care seeking and subsequently reduce the possible harmful use of analgesics, a collaborative physician-patient therapeutic relationship need to be encouraged. To facilitate this, important shifts may be needed in chikungunya sequalae education of both patients and health-care professionals, and policy makers need to revise health systems for the long-term provision of multidisciplinary care to achieve beneficial health outcomes in long-term chikungunya disease.
