Astringency sensitivity to tannic acid: Effect of ageing and salivary proline-rich protein levels

The link between salivary composition and sensitivity to astringency as a function of age has still not been established. In this work, we propose the hypothesis that ageing leads to changes in the concentration of salivary proline-rich proteins (PRPs), which alters the astringency perception threshold with age. To test this hypothesis, astringency sensitivity to tannic acid and saliva was assessed in 30 elderly people and 24 young people. Basic PRPs (bPRPs) and glycosylated PRPs (gPRPs) were quantified immunochemically via western blot analysis. The results showed that the amounts of bPRPs and gPRPs were similar between the young and elderly groups. However, a positive correlation between the gPRP amount and astringency threshold was observed only in the young group, while a negative correlation between the bPRP amount and astringency threshold was observed only in the elderly group. This finding suggests differences in the contribution of PRP type to astringency perception as a function of age.

Age-stratified comorbid and pharmacologic analysis of patients with glioblastoma

Background

Increased age is a strong and unfavorable prognostic factor for patients with glioblastoma (GBM). However, the relationships between stratified patient age, comorbidities, and medications have yet to be explored in GBM patient survival analyses.

Objective

To evaluate co-morbid conditions, tumor-related symptoms, medication prescriptions, and subject age for patients with GBM and to establish potential targets for prospective studies.

Methods

Electronic health records for 565 patients with IDHwt GBM were evaluated at a single center between January 1, 2000 and August 9, 2021 were retrospectively assessed. Data were stratified by MGMT promoter methylation status when available and were used to construct multivariable time-dependent cox models and intra-cohort hazards.

Results

Younger (<65 years of age) but not older (≥65 years) GBM patients demonstrated a worse prognosis with movement related disabilities (P < 0.0001), gait/balance difficulty (P = 0.04) and weakness (P = 0.007), as well as psychiatric conditions, mental health disorders (P = 0.002) and anxiety (P = 0.001). In contrast, older but not younger GBM patients demonstrated a worse prognosis with epilepsy (P = 0.039). Both groups had worse survival with confusion/altered mental status (P = 0.023 vs < 0.000) and an improved survival with a Temozolomide prescription. Older but not younger GBM patients experienced an improved hazard with a prescription of ace-inhibitor medications (P = 0.048).

Conclusion

Age-dependent novel associations between clinical symptoms and medications prescribed for co-morbid conditions were demonstrated in patients with GBM. The results of the current work support future mechanistic studies that investigate the negative relationship(s) between increased age, comorbidities, and drug therapies for differential clinical decision-making across the lifespan of patients with GBM.

Age-Based Heuristics Bias Treatment of Displaced Femoral Neck Fractures in the Elderly

Background

Surgeons performing arthroplasty for femoral neck fractures may rely on mental shortcuts (heuristics) when choosing total hip arthroplasty (THA) vs hemiarthroplasty (HA). We sought to quantify the extent to which age-based heuristics drive decision-making.

Methods

We identified all Medicare beneficiaries from 2017-2018 with femoral neck fractures who underwent THA or HA. We compared the likelihood of THA vs HA among patients admitted within 4 weeks before vs 4 weeks after their birthday for each age under the hypothesis that these cohorts would be similar except for numerical age. We controlled for race/ethnicity, sex, comorbidities, poverty status, and hospital census region in a multivariable regression that included facility-level cluster effects. We generated predicted/adjusted probabilities for THA vs HA for different age transition points.

Results

Thirteen thousand three hundred sixty-six elderly patients were included. One thousand eight hundred sixty-five (14%) received THA and 11,501 (86%) received HA. The likelihood of THA decreased from 50.3% among patients almost 67 to 8% among those ≥85 (P < .001). We found significant decreases in likelihood of THA across age transitions. The largest decrement was at age transition 69 (THA likelihood 28.7% for newly 69 vs 43.3% for almost 69, 33.7% relative change). Female gender, Black race, higher comorbidity burden, and lower socioeconomic status were also associated with a lower likelihood of THA.

Conclusions

Our data demonstrate that patient age transitions seem to influence the choice of THA vs HA. Further research is needed to develop data-driven surgical decision aids for this population.

Secondary infections and long-term outcomes among hospitalized elderly and non-elderly patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and treated with baricitinib: a comparative study from the national centre of Hungary

Baricitinib is considered a first-line treatment for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected adult patients with an associated cytokine storm syndrome (CSS). Our objective was to compare rates of secondary infections and long-term outcomes of elderly and non-elderly patients who received baricitinib for COVID-19. We conducted a single-centre observational study between November 2020 and September 2023, focusing on hospitalized adult SARS-CoV-2 patients with CSS, categorized as elderly (≥ 65 years) and non-elderly (< 65 years). Enrolment, severity stratification, and diagnosis of infectious complications followed predefined criteria. Outcomes of all-cause mortality and rates of non-severe and severe secondary infections were assessed at 1-year post-treatment initiation. Kaplan-Meier analysis was performed for survival analysis. In total, 490 patients were enrolled (median age 65 ± 23 (21-100) years (years, median ± IQR, min-max); 49.18% elderly; 59.59% male). Elderly patients were admitted to the hospital significantly earlier (7 ± 5 days vs. 8 ± 4 days; p = 0.02), experienced a higher occurrence of severe COVID-19 (121/241, 50.21% vs. 98/249, 39.36%; p = 0.02), and required the use of non-invasive ventilation at baseline (167/225, 74.22% vs. 153/236, 64.83%; p = 0.03). At 1 year, all-cause mortality was significantly higher in the elderly subgroup (111/241, 46.06% vs. 29/249, 11.65%; p < 0.01). At 90 days and 1 year, rates of any severe secondary infection were also more prevalent among the elderly (56/241, 23.24% vs. 37/249 14.86%; p = 0.02 and 58/241, 24.07% vs. 39/249, 15.66%; p = 0.02). In conclusion, elderly SARS-CoV-2-infected patients experience a more severe clinical course, higher secondary infection rates, and increased risk for long-term mortality, regardless of immunomodulatory therapy.

Validity and reliability of SEIS-3: An instrument for subjective measuring of strength in older adults

The use of rating of perceived exertion (RPE) has grown substantially, providing a valuable alternative for exercise intensity monitoring, especially for older adults. However, some challenges, such as cross-cultural validity, age-related differences, and reliability issues, necessitate the development of a concise and user-friendly RPE instrument, particularly for strength training in this population. This study aimed to validate the Subjective Effort Induction Scale (SEIS-3), a simplified tool for measuring effort during strength training. SEIS-3 is a graded instrument with three exertion levels: 1) Light effort, 2) Moderate effort, and 3) Strong effort. Twenty seniors, aged 71±7 years, of both genders participated in the study (CEP/Unimontes 2,741,071/2018). We collected maximal isometric voluntary contraction (MIVC) data using a digital dynamometer. Subsequently, participants underwent the initial test, following the three SEIS-3 categories in a randomly assigned order of induced subjective effort. SEIS-3 instrument was evaluated by the approaches:•Linear regression analysis: employed to assess the validity of the instrument.•Intraclass Correlation Coefficient (ICC): employed to assess the reliability of the instrument.SEIS-3 effort categories correlated with MIVC in both hands (R2=0.80, F = 25.596, df=3, p < 0.01 for right hand; R2=0.56, F = 9.132, p < 0.01 for left hand). Test-retest reliability for grip strength across effort categories was excellent (ICC > 0.9). SEIS-3 is a valid and reliable user-friendly tool for accurately assessing and regulating exercise intensity in older adults during strength tasks, benefiting their health, functional capacity, and overall quality of life. This low-cost instrument can help health professionals in their activities.

Effects of resistance training associated with a verbal fluency task on physical performance and cognitive function in frail nursing home residents

OBJECTIVES

Studies examining the effects of dual-task resistance training (RT) on nursing-home residents are still scarce. To add knowledge to this field, the present study compared the effects of 12-week RT and RT plus cognitive task (COG) programs on physical performance and cognitive function in a sample of frail nursing home residents.

METHODS

This is an experimental study that combined data from two studies that examined older adults living in nursing home residences in Brazil. Exercise groups performed a 12-week RT protocol that included four exercises, with 3-4 times (sets) of 8-10 repetitions at 70 %-75 % of 1-repetition maximum (1RM), twice a week. The RT+COG group evoked as many words was possible for specific categories during concentric actions of the squat on the chair (until 90° knee flexion) and seated unilateral knee extension exercises. Global cognitive function and physical performance were evaluated using the Mini-Mental State Examination (MMSE) and Short Physical Performance Battery (SPPB) tests, respectively.

RESULTS

After interventions, participants in the RT+COG and RT groups had significantly greater lower-limb muscle strength compared with the control group (CG). Those in the RT+COG group had greater tandem performance in comparison to RT and CG groups.

CONCLUSIONS

Our findings indicate that RT preserves lower-limb muscle strength in frail nursing home residents, regardless of performance of cognitive tasks. Better balance was exclusively observed in the RT+COG, whereas significant improvements in mobility status were only found in the RT group. The present investigation was based on a small sample of nursing home residents. Larger and more structured studies are necessary to confirm our results.

Study on socio-cultural representations through the analysis of cultural domains

The social and cultural representations of food are essential when it comes to understanding the perception of risk and the trust/distrust that people place on it. In this paper, we analyse the attributes and categories that non-dependent older people aged 65 and over living in Spain use when talking about trust/distrust in relation to food. In order to explore how they manifest different social meanings, we have conducted a study based on an analysis of cultural domains. The results of examining free-listing and pile-sort techniques were triangulated with the narratives obtained from interviews, life histories, food diaries and participatory workshops. The ethnographic research was conducted between June 2021 and June 2022 in the autonomous communities of Andalusia and Catalonia as well as the Valencian Community. Understanding the criteria for trust and distrust through the analysis of cultural domains allows us to better comprehend what food risks are perceived by older people and what value they place on food safety in their food choices. This study aims to provide qualified input for the development of healthier eating habits with recommendations for making ageing an easier process.

History of HPV in HPV-positive elderly women

Background

The aim of this study was to examine the natural course of HPV infection in women of 60 years and older who were HPV positive at inclusion, and any association between HPV positivity in historical samples and dysplasia outcome.

Methods

Eighty-nine women aged 60-82 years, who tested positive for HPV between 2012 and 2016 were included. Sampling for cytology and/or histology was also performed. HPV genotyping was carried out on archived material back to 1999.

Results

Of the 89 HPV-positive women 16 had HSIL, 34 had LSIL and 39 were benign at inclusion. Of the women with HSIL, 50.0% had the same HPV type in the archive samples, 12.5% had another type, and 37.5% were HPV negative. Among the 34 women with LSIL, 47.1% had the same HPV type in archive samples, 5.8% had another type, and 47.1% were HPV negative. Of the 39 women without dysplasia at inclusion, 25.6% had the same HPV type in archive samples, 5.1% had another HPV type and 69.2% were HPV negative.

Conclusion

Surprisingly few of the elderly women thus seem to have a history with the same or any HPV infection the years before being diagnosed with an HPV infection and dysplasia. The significance of an HPV infection for dysplasia development in elderly women is still not fully understood.

Comparison of rerupture rates after operative and nonoperative management of Achilles tendon rupture in older populations: Systematic review and meta-analysis

Background

This systematic review and meta-analysis investigated the treatment for Achilles tendon rupture (ATR) associated with the lowest risk of rerupture in older patients.

Methods

Five databases were searched through September 2022 for studies published in the past 10 years analyzing operative and nonoperative ATR treatment. Studies were categorized as "nonelderly" if they reported only on patients aged 18-60 years. Studies that included at least 1 patient older than age 70 were categorized as "elderly inclusive." Of 212 studies identified, 28 were eligible for inclusion. Of 2965 patients, 1165 were treated operatively: 429 (37%) from elderly-inclusive studies and 736 (63%) from nonelderly studies. Of the 1800 nonoperative patients 553 (31%) were from nonelderly studies and 1247 (69%) were from elderly-inclusive studies.

Results

For nonoperative treatment, the rate of rerupture was higher in nonelderly studies (83/1000 cases, 95% CI = 58, 113) than in elderly-inclusive studies (38/1000 cases, 95% CI = 22, 58; P<.001). For operative treatment no difference was found in the rate of rerupture between nonelderly studies (7/1000 cases, 95% CI = 0, 21) and elderly-inclusive studies (12/1000 cases, 95% CI = 0, 35; P<.78). Overall, operative treatment was associated with a rerupture rate of 1.5% (95% CI: 1.0%, 2.8%) (P<.001), which was lower than the 5% rate reported by other studies for nonoperative management (P<.001).

Conclusion

Older patients may benefit more than younger patients from nonoperative treatment of ATR. More studies are needed to determine the age at which rerupture rates decrease among nonoperatively treated patients.

The impact of frailty as a critical mediator causing postoperative neurocognitive disorders in postoperative cardiac patients

Frailty is prevalent in elderly cardiac patients and may be a critical predictor of post-operative neurocognitive disorders (PND). The aim of this review was to demonstrate the correlation of frailty with PND in postsurgical elder patients. A review of published literature and bibliometric analysis was undertaken. Electronic databases from 2009 to 2022 were searched to identify articles that evaluated the relationship between frailty and PND in aging populations. Demographic data, type of surgery performed, frailty measurement, and impact of frailty on PND were extracted from the selected studies. The quality of the studies and risk of bias were assessed by the Newcastle-Ottawa Quality Assessment Scale, and the included articles were assessed as medium to high quality. Eighty-one studies were selected for the Bibliometric review in terms of research trends and hotpots. Additionally, 35 observational studies (prospective and retrospective cohorts) were selected for this review. The mean age ranged from 63 to 84 years and included patients undergoing cardiac, orthopedic, and other surgeries who had cardiac symptoms. Regardless of how frailty was measured, the strongest evidence in terms of numbers of studies, consistency of results, and study quality was for associations between frailty and PND. This analysis found a steadily growing focus on frailty and PND research in cardiac and other patients. The observational studies account for the majority of this area, and frailty occurred in the older cardiac patients over 60 years of age, and pre-screening of frailty can be predictive of PND and mortality.

Telephone follow-up by nurse practitioners of geriatric patients discharged from the emergency department after traumatic injury

INTRODUCTION

Geriatric patients discharged from the emergency department (ED) after an injury are at risk for adverse outcomes. Older patients are at a higher risk for sensory impairments and cognitive problems which can make comprehension of discharge instructions more difficult. Moreover, geriatric patients often have limited skills with or access to alternative sources of information, such as hospital web pages or phone applications, which could put them at a higher risk of undertreatment. Implementing telephone follow-up after discharge presents a potential solution to enhance information transfer and address problems related to the injury.

METHODS

An exploratory cohort study was conducted in the ED of an inner-city hospital in the Netherlands between 2019-2020. Patients ≥70 years were included if they presented with an injury and were discharged home from the ED. Telephone follow-up was performed by an ED nurse practitioner within 48 hours after discharge to address any problems or questions relating to the injury. Feasibility was assessed by determining whether the intervention could be performed within the allotted time period during normal work hours (1 h per day). The frequency and type of additional advice given, as well as patient satisfaction with the intervention, were documented.

RESULTS

635 patients were eligible for inclusion, and 266 completed the intervention (median age 77 years; 32 % male). Nurse practitioners were able to complete the intervention on over 90 % of days. A total of 64 % of patients received additional advice during the telephone call, mostly related to pain medication adjustments and instructions to contact their GP. Patient satisfaction with the intervention was high (median score 8/10).

CONCLUSION

Telephone follow-up is a feasible intervention that may be able to enhance older patients' comprehension of discharge instructions and help identify new problems after discharge. During the follow-up call, the majority of patients received additional advice, indicating a potential demand for this intervention. The main limitation was that not all eligible patients were approached or did not want to participate in the intervention. Future studies should investigate whether telephone follow-up can effectively reduce adverse events and improve the quality of life for these patients.

Prognostic nomogram for early-stage cervical cancer in the elderly: A SEER database analysis

Background

To identify key clinical factors affecting the survival of elderly patients with early-stage cervical cancer and to construct a nomogram for predicting their prognosis.

Methods

Patients (aged ≥ 65 years old) diagnosed with cervical cancer between 2004 and 2015 at clinical stages IA to IIA were included in this study. Diagnosis was confirmed via pathological examination, and the cases were randomly divided into a training or a validation group in a 7:3 ratio. Univariate and multivariable Cox regression analyses were performed to identify independent factors affecting the prognosis of elderly early-stage cervical cancer patients, based on which a nomogram was constructed to predict their 12-, 24- and 36-month overall survival (OS). The nomogram's performance was evaluated using receiver operating characteristic (ROC) curves, calibration curves and decision curve analysis (DCA) curves.

Results

A total of 686 patients were identified as eligible and assessed. Multivariable Cox proportional hazard regression analysis revealed that age, tumor diameter, marital status and surgical intervention were independent prognostic factors for elderly individuals with early-stage cervical cancer, which were then used to construct the nomogram. The calibration curves showed a strong correlation between predicted and observed survival rates, and Kaplan-Meier survival curves for different risk subgroups demonstrated significant survival differences (P < 0.001). DCA confirmed the nomogram's clinical utility in predicting the prognosis of elderly patients with early-stage cervical cancer.

Conclusion

The prognostic model developed in this study can accurately predict the OS of elderly patients with early-stage cervical cancer, showing high concordance with actual clinical outcomes.

Prevalence and risk factors of osteoporotic fracture among the elderly population in China: a multicenter cross-sectional study

PURPOSE

Prevalence of osteoporotic fracture (OPF) is increasing with ageing, resulting in a significant financial burden for healthcare. However, research on the nationwide epidemiological data of OPF in Chinese elderly is still scarce. The aim of this study was to investigate the prevalence and risk factors of OPF in Chinese population aged 60 years or order.

METHODS

A cross-sectional survey was conducted in an elderly Chinese population in five centres. Questionnaire investigation and imaging examination were taken in all participants to identify OPF prevalence and risk factors. Diagnosis of OPF was determined based on imaging of vertebral fractures or history of fall-related fractures. We then used multivariate logistic regression model to analyze the associations between the potential risk factors and OPF.

RESULTS

The overall prevalence of OPF in population aged 60 years or older was 24.7% (1,071/4,331), showing an increasing trend with age (P < 0.001). The prevalence of OPF was geographically distinct (P < 0.001), but similar between men and women (P > 0.05). Up to 96.8% of OPFs consisted of vertebral fractures, especially involving T11, T12, and L1 segments. Advanced age (≥ 80), vision loss, severe hearing loss, multiple exercise forms, chronic kidney disease, osteoarthritis, and trauma-related vertebral fractures were significantly associated with risk factors, while education level and vitamin D supplementation were associated with protective factors of OPF.

CONCLUSION

High prevalence of OPF is a serious threat to bone health among elderly people in China. There is an urgent need for effective strategies to diagnose, prevent, and treat OPF in elderly adults.

The BAND score: A simple model for upfront prediction of poor outcomes despite successful stroke thrombectomy

BACKGROUND

While endovascular thrombectomy (EVT) is beneficial for patients with acute large vessel occlusion ischemic strokes, a significant portion of patients still do poorly despite successful recanalization. Identifying patients at high risk for poor outcomes can be helpful for future clinical trial design and optimizing acute stroke triage.

METHODS

Consecutive EVT patients were identified from 2016 to 2021 at a Comprehensive Stroke Center, and clinical information was recorded. Poor outcome was defined as a 90-day modified Rankin Scale (mRS) of 4 or greater despite achieving a modified thrombolysis in cerebral infarction (mTICI) score of 2b or greater. Multivariable regression analyses were used to identify risk factors for poor outcomes, and a scoring system was constructed.

RESULTS

483 patients with successful recanalization were identified. From a randomly selected training cohort (n = 357), the 10-point BAND score was constructed from independent risk factors for poor outcomes: baseline disability (1 point: baseline mRS ≥ 2), age (1 point: 60-69 years, 2 points: 70-79 years, 3 points: 80-84 years, 4 points: 85 years or older), NIHSS (2 points: 13-17, 3 points: 18-22, and 4 points: ≥ 23), and delay from last known normal (1 point: ≥ 6 h). The BAND score was significantly associated with rates of poor outcomes (p < 0.001), and it achieved an area under the receiver-operating characteristic curve (AUC) of 0.80 (95 %CI 0.76-0.85) in our training cohort and 0.78 (95 %CI 0.70-0.86) in our validation cohort (n = 126). Overall, the BAND score had a significantly higher AUC value than the widely validated THRIVE score and the THRIVE-EVT calculation (p = 0.001 and 0.029, respectively). Among patients with high BAND scores (7 or higher), 88.2 % had poor outcomes.

CONCLUSION

The BAND score is a simple tool to predict poor outcomes despite successful recanalization. Future studies are needed to confirm the BAND score's external validity.

The association between intensity-specific physical activity and the number of multiple chronic diseases among Chinese elderly: A study based on the China Health and Retirement Longitudinal study (CHARLS)

Background

With ageing, the elderly are facing a complex situation where multiple chronic diseases coexist. This paper aims to investigate the effect of intensity-specific physical activity on the number of multiple chronic diseases in the elderly.

Methods

Our data came from wave 4 of the China Health and Retirement Longitudinal Survey (CHARLS), which involved 10,341 residents aged ≥ 60 years. The intensity-specific physical activity was divided into two categories: moderate-intensity physical activity (MPA) lasting ≥ 150 min/week and vigorous-intensity physical activity (VPA) lasting ≥ 75 min/week. Data on 14 types of chronic diseases were collected. Propensity score matching (PSM) with controlling nine confounding factors were used to analyse the effects of intensity-specific physical activity.

Results

Among 10,341 samples, 40.12% of the elderly often participated in MPA and 25.72% participated in VPA. The PSM results showed that performing 150 min/week of MPA leads to 0.0675(P<0.05) fewer multiple chronic diseases than not achieving this standard, and VPA up to 75 min/week leads to 0.0785(P<0.05) fewer multiple chronic disease than that does not meet this criterion. Additionally, VPA is more effective than MPA.

Conclusion

Both MPA of at least 150 min/week and VPA of at least 75 min/week can significantly reduce the number of multiple chronic diseases in elderly. Elderly people should increase their exercise intensity as much as possible while ensuring safety.

Management of glioblastoma in elderly patients: A review of the literature

High grade gliomas are the most common primary aggressive brain tumours with a very poor prognosis and a median survival of less than 2 years. The standard management protocol of newly diagnosed glioblastoma patients involves surgery followed by radiotherapy, chemotherapy in the form of temozolomide and further adjuvant temozolomide. The recent advances in molecular profiling of high-grade gliomas have further enhanced our understanding of the disease. Although the management of glioblastoma is standardised in newly diagnosed adult patients there is a lot of debate regarding the best treatment approach for the newly diagnosed elderly glioblastoma patients. In this review article we attempt to summarise the findings regarding surgery, radiotherapy, chemotherapy, and their combination in order to offer the best possible management modality for this group of patients. Elderly patients 65-70 with an excellent functional level could be considered as candidates for the standards treatment consisting of surgery, standard radiotherapy with concomitant and adjuvant temozolomide. Similarly, elderly patients above 70 with good functional status could receive the above with the exception of receiving a shorter course of radiotherapy instead of standard. In elderly GBM patients with poorer functional status and MGMT promoter methylation temozolomide chemotherapy can be considered. For elderly patients who cannot tolerate chemotherapy, hypofractionated radiotherapy is an option. In contrast to the younger adult patients, it seems that a careful individualised approach is a key element in deciding the best treatment options for this group of patients.

Comparison of morbidity and mortality after radical cystectomy between individuals older and younger than 80 years: a systematic review and meta-analysis

OBJECTIVE

To compare outcomes related to survival and post-operative complications in individuals older and younger than 80 years with bladder cancer undergoing radical cystectomy (RC).

METHODS

We conducted a systematic search using three large databases: PubMed, EMBASE, and Scopus. We included observational studies comparing outcomes between individuals older than 80 years and younger patients undergoing RC. The outcomes of interest included overall survival, disease-specific survival, progression-free survival, and risk of post-operative complications. We applied a random effects model for the analysis and reported pooled effect sizes as odds ratios (ORs) or hazards ratios (HRs) along with 95% confidence intervals.

RESULTS

We analyzed 21 studies. Our results show that individuals older than 80 years had higher risks of mortality at 30 days (OR 2.82; 95% CI 1.97, 4.04), 90 days (OR 3.34; 95% CI 2.61, 4.27), 12 months (HR 3.03; 95% CI 2.64, 3.49), and 24 months (HR 3.54; 95% CI 2.27, 5.50) of the post-operative follow-up than younger individuals. In addition, individuals older than 80 years also had poor 5-year survivals (HR 2.17; 95% CI 1.64, 2.88), an increased risk of 5-year cancer-specific mortality (HR 1.58; 95% CI 1.24, 2.03), poor 5-year recurrence free survivals (HR 1.49; 95% CI 1.07, 2.08), and high complications risks (OR 1.20; 95% CI 1.02, 1.42) when compared to younger patients.

CONCLUSION

Individuals older than 80 years undergoing RC are likely to have poor survival-related outcomes and increased complications risks. Pre-planned comprehensive geriatric assessments (CGAs) may be needed to offer better peri- and post-operative care to improve the outcomes in this patient population.

Uptake of pneumococcal vaccines in older Australian adults before and after universal public funding of PCV13

BACKGROUND

In 2020 Australia changed the funded universal older adult pneumococcal vaccination program from use of the 23-valent pneumococcal polysaccharide vaccine (PPV23) at age 65 to the 13-valent pneumococcal conjugate vaccine (PCV13) at age 70 years. We investigated uptake of both PCV13 and PPV23 in older adults before and after the program change.

METHODS

We analysed a national dataset of records of patients attending general practices (GPs). We included regular attendees aged 65 or above in 2020. Cumulative uptake of PCV13 and monthly uptake of PPV23 was compared for the two periods before (January 2019 to June 2020) and after (July 2020 to May 2021) the program change on 1 July 2020, by age groups and presence of comorbid conditions.

RESULTS

Our study included data from 192,508 patients (mean age in 2020: 75.1 years, 54.2 % female, 46.1 % with at least one comorbidity). Before July 2020, for all adults regardless of underlying comorbidities, the cumulative uptake of PCV13 was < 1 % but by May 2021, eleven months after the program changes, cumulative uptake of PCV13 had increased among those aged 70-79 years (without comorbidity: 16.3 %; with comorbidity: 21.1 %) and 80 + years (without comorbidity: 13.5 %; with comorbidity: 17.7 %), but not among those aged 65-69 years (without comorbidity: 1.3 %; with comorbidity: 3 %). Monthly uptake of PPV23 dropped following the program change across all age groups.

CONCLUSIONS

Changes in uptake of PCV13 and PPV23 among those aged 70 + years were consistent with program changes. However, PCV13 uptake was still substantially lower in individuals aged 65-69 years overall and in those with comorbidities.

A prospective randomized control trial comparing outcomes of casting, pinning, and plating for distal end of radius fractures (AO type A2, A3, C1, or C2) in the elderly population

PURPOSE

With this prospective randomized control trial (RCT), we aim to provide the outcome analyses of the three most used treatment modalities for distal end of radius (DER) fracture management in the elderly.

METHODS

A prospective randomized control trial was performed. Fifty-two patients with DER fractures (AO A2, A3, C1, or C2) were randomized to the casting (n = 17), percutaneous pinning (n = 18), and the volar plating group (n = 17). Radiological measurements measured were radial inclination (RI), radial height (RH), volar tilt (VT), and ulnar variance (UV). The outcome was measured based on range-of-motion, grip strength, Patient-Related-Wrist-Evaluation (PRWE) score, and the Quick-Disabilities-of-the-Arm-Shoulder-Hand (QDASH) score.

RESULTS

Immediate post-operative and 1-year-follow-up X-rays showed a significant difference measurement between the groups (p < 0.05). Pairwise comparisons of the casting and pinning groups (p < 0.05) and the casting and plating groups (p < 0.05) revealed significant differences at the 1-year follow-up, but not the pinning and plating groups (p > 0.05). The analysis found significant differences in clinical outcomes after 1 month of follow-up, with the plating group outperforming the other two (p > 0.05). However, after a year of follow-up, all groups had comparable outcomes; however, the plating group showed improved palmar flexion (p < 0.001), radial deviation (p < 0.001), and a lower PRWE score (p < 0.05), indicating better wrist function. Complications were more in casting group.

CONCLUSION

The study found a radiologically significant difference between groups throughout the follow-up, but it did not affect functional results. Clinical outcomes were similar across the groups, with plating showing better palmar flexion and radial deviation. Grip strength was also better in the plating group, but statistically insignificant. The study suggests plating should be chosen over other treatments for high-demand patients.

Group-Based Trajectory Modeling of Fluid Balance in Elderly Patients with Acute Ischemic Stroke: Analysis from Multicenter ICUs

INTRODUCTION

Acute ischemic stroke (AIS) significantly contributes to severe disability and mortality among the elderly. This study aims to explore the association between longitudinal fluid balance (FB) trajectories and clinical outcomes in elderly patients with AIS. Our hypothesis posits the existence of multiple latent trajectories of FB in patients with AIS during the initial 7 days following ICU admission.

METHODS

Patients (age ≥ 65 years) with AIS and continuous FB records were identified from two large databases. Group-based trajectory modeling identified latent groups with similar 7-day FB trajectories. Subsequently, multivariable logistic and quasi-Poisson regression were employed to evaluate the relationship between trajectory groups and outcomes. Additionally, nonlinear associations between maximum fluid overload (FO) and outcomes were analyzed using restricted cubic spline models. To further validate our findings, subgroup and sensitivity analysis were conducted.

RESULTS

A total of 1146 eligible patients were included in this study, revealing three trajectory patterns were identified: low FB (84.8%), decreasing FB (7.2%), and high FB (7.9%). High FB emerged as an independent risk factor for in-hospital mortality. Compared with those without FO, patients with FO had a 1.57-fold increased risk of hospital mortality (adjusted odd ratio (OR) 1.57, 95% confidence interval (CI) 1.08-2.27), 2.37-fold increased risk of adverse kidney event (adjusted OR 2.37, 95% CI 1.56-3.59), and 1.33-fold increased risk of prolonged ICU stay (adjusted incidence rate ratio (IRR) 1.33, 95% CI 1.19-1.48). The risk of hospital mortality and adverse kidney event increased linearly with rising maximum FO (P for non-linearity = 0.263 and 0.563, respectively).

CONCLUSION

Daily FB trajectories were associated with adverse outcomes in elderly patients with AIS. Regular assessment of daily fluid status and restriction of FO are crucial for the recovery of critically ill patients.

Treatment of Myelodysplastic Syndromes for Older Patients: Current State of Science, Challenges, and Opportunities

PURPOSE OF REVIEW

Myelodysplastic syndromes/neoplasms (MDS) represent a diverse group of pathologically distinct diseases with varying prognoses and risks of leukemia progression. This review aims to discuss current treatment options for elderly patients with MDS, focusing on patients ineligible for intensive chemotherapy or allogenic hematopoietic stem cell transplantation (HSCT). The challenges associated with treatment in this population and emerging therapeutic prospects are also explored.

RECENT FINDINGS

Recent advancements in molecular diagnostics have enhanced risk stratification by incorporating genetic mutations, notably through the molecular International Prognostic Scoring System (IPSS-M). Lower-risk MDS (LR-MDS) treatment ranges from observation to supportive measures and erythropoiesis-stimulating agents (ESAs), with emerging therapies like luspatercept showing promise. High-risk MDS (HR-MDS) is treated with hypomethylating agents (HMAs) or allogenic HSCT, but outcomes remain poor. Elderly MDS patients, often diagnosed after 70, pose challenges in treatment decision-making. The IPSS-M aids risk stratification, guiding therapeutic choices. For LR-MDS, supportive care, ESAs, and novel agents like luspatercept are considered. Treatment of HR-MDS involves HMAs or allogenic HSCT. Emerging treatments, including oral HMAs and novel agents targeting FLT3, and IDH 1/2 mutations, show promise. Future research should refine treatment strategies for this elderly population focusing on quality-of-life improvement.

Prediction of pure tone thresholds using the speech reception threshold and age in elderly individuals with hearing loss

OBJECTIVE

Early detection and effective management of hearing loss constitute the key to improving the quality of life of individuals with hearing loss. However, in standardized pure tone audiometry, it is sometimes difficult for elderly patients to understand and follow all instructions. Audiologists also require time, expertise, and patience to ensure that an elderly can identify the faintest levels of stimuli during a hearing test. Therefore, this study aimed to devise and validate a formula to predict the pure tone threshold at each frequency across 0.5-4 kHz (PTTs) using speech reception threshold.

METHODS

The 1226 audiograms of hearing-impaired individuals aged 60-90 years were reviewed. The random sample function randomly assigned 613 participants to the training and testing sets each. A linear model was created to predict the PTT value at each frequency based on variables significant at all frequencies across 0.5-4 kHz. The adjusted-R2 value was considered to indicate the performance of the predictive model. Pearson's correlation coefficient was used to describe the relationship between the actual and predicted PTT at 0.5, 1, 2, and 4 kHz among the testing set to measure the performance of the proposed model.

RESULTS

The predictive model was devised using variables based on the speech recognition threshold (SRT) after adjusting with age in the training set. The overall prediction accuracy demonstrated a higher adjusted-R2 ranging from 0.74 to 0.89 at frequencies of 0.5, 1, and 2 kHz, whereas a low percentage of explained variance was observed at 4 kHz (adjusted-R2 = 0.41). This predictive model can serve as an adjunctive clinical tool for guiding determination of the PTTs. Moreover, the predicted PTTs can be applied in the hearing aid programming software to set appropriate hearing aid gain using standard prescriptive formulas.

Long-term effects of abatacept on atherosclerosis and arthritis in older vs. younger patients with rheumatoid arthritis: 3-year results of a prospective, multicenter, observational study

BACKGROUND

We aimed to reveal the effect of abatacept (ABT) on atherosclerosis in rheumatoid arthritis (RA) patients, 3-year efficacy for arthritis, and safety in a population of older vs. younger patients.

METHODS

In this open-label, prospective, observational study, patients were stratified into four groups: younger (20-64 years old) and older (≥ 65 years) patients taking ABT (AY and AO) and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) (CY and CO). Primary endpoints were change from baseline in mean intima-media thickness (IMT) of the common carotid artery, IMT max (bulbus, bifurcation, and internal and common carotid artery), and plaque score at Week 156. Disease activity, retention rate, and adverse effects were also evaluated.

RESULTS

The ABT group (AY + AO) tended to have smaller increases in mean IMT, max IMT, and plaque score than the csDMARD group (CY + CO) at Week 156, although the differences between groups were not statistically significant. Multivariate analysis showed significantly lower increases in plaque score with ABT than with csDMARDs, only when considering disease activity at 156 weeks (p = 0.0303). Proportions of patients with good or good/moderate European League Against Rheumatism response were higher in the ABT group, without significant difference between older and younger patients. No significant differences were observed in ABT retention rates between older and younger patients. Serious adverse effects, especially infection, tended to be more frequent with ABT than with csDMARDs, although no significant differences were found.

CONCLUSIONS

ABT may decelerate atherosclerosis progression and may be useful for patients with high risk of cardiovascular disease, such as older patients.

Association of serum uric acid with functional disability in older subjects: a population-based study

BACKGROUND

The role of serum uric acid (SUA) in the development of adverse health outcomes in advanced age is still uncertain.

AIMS

The aim of the study was to assess the association of disability with SUA levels in older community-dwelling subjects.

METHODS

We assessed the association of disability with SUA in all 351 inhabitants of Tuscania (Italy) aged 75+. Functional ability was estimated using the instrumental activities of daily living (IADLs).

RESULTS

In logistic regression, increasing SUA levels were associated with disability (OR = 1.22; 95%CI = 1.01-1.48; P = .036), after adjusting. The association was independent of both gender and age (P for interaction > 0.050). SUA levels above 5.5 mg/dL best predicted disability.

CONCLUSIONS

In older subjects, SUA levels are associated with disability; the cut off level above 5.5 mg/dL might be adopted in pharmacological trials aiming at reducing the incidence and progression of disability by reducing SUA, and for identifying subjects at increased risk of disability.

Treatment of elderly patients with head and neck cancer in an aging society: Focus on geriatric assessment and surgical treatment

Previous studies of the treatment of elderly head and neck cancer (HNC) patients were very limited and sometimes controversial. Although conclusions differ across various reports, it is often concluded that advanced chronological age does not directly affect prognosis, but that comorbidities and declines in physical and cognitive functions promote the occurrence of adverse events, especially with surgical treatment. Geriatric assessment (GA) and its screening tools are keys to help us understand overall health status and problems, predict life expectancy and treatment tolerance, and to influence treatment choices and interventions to improve treatment compliance. In addition, personal beliefs and values play a large role in determining policies for HNC treatment for elderly patients, and a multidisciplinary approach is important to support this. In this review, past research on HNC in older adults is presented, and the current evidence is explained, focusing on the management of elderly HNC patients, with an emphasis on the existing reports on each treatment stage and modality, especially the surgical procedures.

The SaVe project - Sarcopenia and Vertigo in aging patients with colorectal cancer: A study protocol for three randomized controlled trials

INTRODUCTION

Older patients with cancer range from fit to frail with various comorbidities and resilience to chemotherapy. Besides nausea and fatigue, a significant number of patients experience dizziness and impaired walking balance after chemotherapy, which can have great impact on their functional ability and health related quality of life. Symptoms are easily overlooked and therefore often underreported and managed, which is why symptoms could end up as long-lasting side effects. The aim of this study is to investigate the development of dizziness, decline in walking balance, and sarcopenia and the effect of a comprehensive geriatric assessment and 12 weeks of group-based exercise on these symptoms. The exercise intervention includes vestibular and balance exercises, and progressive resistance training, to counteract the symptoms in older patients with colorectal cancer treated with chemotherapy.

MATERIALS AND METHODS

This is a randomized controlled trial including patients ≥65 years initiating (neo)adjuvant or first-line palliative chemotherapy for colorectal cancer. Patients will undergo a comprehensive assessment program including measures of vestibular function, balance, muscle strength, mass, and endurance, peripheral and autonomic nerve function, and subjective measures of dizziness, concern of falling, and health related quality of life. Tests will be performed at baseline, 12, and 24 weeks. Patients will be placed in three different randomized controlled trials depending on chemotherapy regimen and randomized 1:1 to comprehensive geriatric assessment and exercise three times/week or control. Participants in both groups will continue with usual care, including standardized oncological treatment. In total, 150 patients are needed to assess the two primary outcomes of (1) maintenance of walking balance assessed with Dynamic Gait Index and (2) lower limb strength and endurance assessed with 30 Second Sit-to-Stand Test at 12 weeks. The primary outcomes will be analyzed using a mixed linear regression model investigating the between-group differences.

DISCUSSION

Trial enrollment began in April 2023 and is the first trial to evaluate reasons for dizziness, decline in walking balance, and sarcopenia in older patients receiving chemotherapy. The trial will provide new and valuable knowledge in how to assess, manage, and prevent dizziness, decline in walking balance, and sarcopenia in older patients with colorectal cancer.

Open versus minimally invasive nephroureterectomy in octogenarians: An analysis of surgical approach trends, outcomes, and survival analysis with propensity matching

INTRODUCTION

Upper tract urothelial carcinoma (UTUC) is a rare disease accounting only for 5%-10% of urothelial carcinoma (UC). For localized high-risk disease, radical nephroureterectomy (RNU) is the standard of care. While minimally invasive (MIS) RNU has not been shown to decisively improve overall survival (OS) compared to open surgery, MIS RNU has been associated with reduced hospital length of stay (LOS), blood transfusion requirements and improved recovery, which are important considerations when treating older patients. The purpose of this study is to examine trends in surgical approach selection and outcomes of open vs. MIS RNU in patients aged ≥80 years.

METHODS

Using the National Cancer Database (NCDB), patients aged ≥80 years who underwent open or MIS (either robotic or laparoscopic) RNU were identified from 2010 to 2019. Demographic, patient-related, and disease-specific factors associated with either open or MIS RNU were assessed using multivariate logistic regression models. Survival analysis was conducted using Kaplan-Meier plots and Cox-proportional hazard regression. Inverse probability of treatment weighting (IPTW) was utilized to adjust for confounding variables. Survival analysis was also conducted on the IPTW adjusted cohort using Kaplan-Meier plots and Cox-proportional hazard regression.

RESULTS

5,687 patients were identified, with 1,431 (25.2%) and 4,256 (74.8%) patients undergoing open and MIS RNU respectively. The proportion of RNU performed robotically has increased from 12.5% in 2010 to 50.4% in 2019. MIS was associated with a shorter hospital LOS (4.7 days versus 5.9 days, SMD 23.7%). Multivariate analysis revealed that MIS was associated with a significant reduction in 90-day mortality (OR: 0.571; 95%CI: 0.34-0.96, P = 0.033) and improved median OS (53.8 months [95%CI: 50.9-56.9] vs 42.35 months [95%CI: 38.6-46.8], P < 0.001) compared to open surgery. IPTW-adjusted survival analysis revealed improved median OS with MIS when compared to open surgery, with a survival benefit of 46.1 months (95%CI: 40.2-52.4 months) versus 37.7 months (95%CI: 32.6-46.5 months, P = 0.0034) respectively. IPTW-adjusted cox proportional hazard analysis demonstrated that MIS was significantly associated with reduced mortality (HR 0.76, 95%CI: 0.66-0.87, P < 0.001).

CONCLUSION

In octogenarians undergoing RNU, MIS is associated with improved median OS and 90-day mortality.

A qualitative perspective of working women care providers and care receivers on eldercare: a study from India

BACKGROUND

The paper aims to explore the elderly caregiving process in India from the perspective of both elderly as well as working women care providers, along with the challenges faced and the coping strategies adopted by them during the process.

METHODS

In-depth interviews with 48 participants (care providers and care receivers) from 25 multi-generational households were conducted in the slums of Mumbai and analysed using QSR-NVivo-10.

RESULTS

Working women care providers supported the needs of the dependent elderly along with performing household chores and paid work. However, the way the care was perceived and demanded, was not often same as delivered by the care providers. Care provider suffered silently with poor social, physical and emotional welling in absence of support system and lack of time. Sometimes, physically exhausted care providers unknowingly resorted to elderly abuse and neglect. At the same time, a bidirectional flow of support from elderly also existed in the form of childcare, household chores and financial support. Though caregiving overstrained the care providers, strong family ties, acknowledgement of the contributions of the elderly during their young days, and the desire to set a precedent for the young generation did not let them step back from their duties. The main coping mechanism for both care receivers and providers was largely centred around the notion of acceptance of their situation.

CONCLUSION

Conversations between generations can help in enhancing family ties and reduce conflicts. The support of family and community can also ease the burden of caregiving.

Predictive value of the systemic immune-inflammation index on one-year mortality in geriatric hip fractures

BACKGROUND

Geriatric hip fractures are associated with a high incidence of mortality. This study examines the predictive value of the systemic immune-inflammation index (SII) on one-year mortality in elderly hip fracture patients.

METHODS

A single-center retrospective study was conducted between February 2017 and October 2020. Three hundred and eleven surgically treated consecutive hip fracture patients were included in the study. Admission, postoperative first day, and postoperative fifth-day SII values were calculated. The receiver operating characteristic (ROC) curve was used to calculate the cut-off values, and patients were divided into high and low groups according to these cut-off values. After univariate Cox regression analysis, significant factors were included in the multivariate Cox proportional hazards model to adjust the effect of covariates and explore independent predictive factors associated with mortality. Further subgroup analysis was performed to evaluate the accuracy of the results for different clinical and biological characteristics.

RESULTS

The mean age was 80.7 ± 8.0 years, and women made up the majority (67.8%) of the patients. The one-year mortality rate was 28.0%. After univariate and multivariate analyses, high postoperative fifth-day SII remained an independent predictor of one-year mortality (adjusted HR 2.16, 95% CI 1.38-3.38, p = 0.001). Older age, male gender, Charlson comorbidity index (CCI) ≥ 2, and hypoalbuminemia were found to be other independent predictors. The optimal cut-off value of the postoperative fifth-day SII was calculated at 1751.9 units (p < 0.001).

CONCLUSION

The postoperative fifth-day SII is a simple and useful inflammatory biomarker for predicting one-year mortality in patients with hip fracture.

The secondary prevention of coronary heart disease in US adults 75 Years and older in daily practice: Results from the National Health and Nutrition Examination Survey 1999-2018 survey

Background

Pharmacologic therapies, risk factor control, and lifestyle alterations were independently proven to reduce long-term cardiovascular events. However, comprehensive research examining the extent to which individuals aged 75 and above in the United States adhere to national guidelines for the secondary prevention of coronary heart disease is limited. Therefore, the primary objective of this study was to examine the current state of secondary prevention of coronary heart disease in persons 75 years of age and older in the United States and to examine the factors that contribute to inadequate drug utilization and poor control of numerous risk factors.

Methods

We identified patients over 75 years of age with coronary heart disease based on the National Health and Nutrition Examination Survey from 1999 to 2018 and analyzed the adequacy of risk factor control and adherence to lifestyle and medication recommendations to assess the effectiveness of coronary heart disease management. Logistic regression analysis was used to identify factors associated with uncontrolled risk factors or noncompliance with recommended medications.

Results

We collected information from 1566 known coronary heart disease patients aged ≥75 years of age. The majority were at target goals for blood pressure (58.88%), low-density lipoprotein cholesterol (66.85%), and glycated hemoglobin (76.12%). Only 27.8% and 36.06% were at targets for body mass index and waist circumference, respectively. 91.95% reported smoking cessation, 85.98% followed recommended alcohol consumption, whereas only 10.34% reported sufficient physical activity. For β blockers, angiotensin -converting enzyme inhibitors/angiotensin receptor blockers, statins, and antiplatelet drugs, the utilization of indicated therapy was 54.41%, 49.36%, 54.79%, and 19.03%, respectively (6.26% for all 4 medications). The results of the logistic regression analysis demonstrated that diabetes mellitus and metabolic syndrome were critical markers of numerous uncontrolled risk variables as well as noncompliance with medication regimens.

Conclusions

A vast majority of coronary heart disease patients ≥75 years in the USA exhibited suboptimal overall control of critical coronary heart disease risk factors. For this patient population, more knowledge is necessary to enable patients to receive continuous support, guidance, and counseling.

Prevalence and risk factors of diabetes mellitus among elderly patients in the Lugu community

BACKGROUND

Age is a significant risk factor of diabetes mellitus (DM). With the develop of population aging, the incidence of DM remains increasing. Understanding the epidemiology of DM among elderly individuals in a certain area contributes to the DM interventions for the local elderly individuals with high risk of DM.

AIM

To explore the prevalence of DM among elderly individuals in the Lugu community and analyze the related risk factors to provide a valid scientific basis for the health management of elderly individuals.

METHODS

A total of 4816 elderly people who came to the community for physical examination were retrospectively analyzed. The prevalence of DM among the elderly was calculated. The individuals were divided into a DM group and a non-DM group according to the diagnosis of DM to compare the differences in diastolic blood pressure (DBP) and systolic blood pressure (SBP), fasting blood glucose, body mass index (BMI), waist-to-hip ratio (WHR) and incidence of hypertension (HT), coronary heart disease (CHD), and chronic kidney disease (CKD).

RESULTS

DM was diagnosed in 32.70% of the 4816 elderly people. The BMI of the DM group (25.16 ± 3.35) was greater than that of the non-DM group (24.61 ± 3.78). The WHR was 0.90 ± 0.04 in the non-DM group and 0.90 ± 0.03 in the DM group, with no significant difference. The left SBP and SBP in the DM group were 137.9 mmHg ± 11.92 mmHg and 69.95 mmHg ± 7.75 mmHg, respectively, while they were 126.6 mmHg ± 12.44 mmHg and 71.15 mmHg ± 12.55 mmHg, respectively, in the non-DM group. These findings indicate higher SBP and lower DBP in DM patients than in those without DM. In the DM group, 1274 patients were diagnosed with HT, accounting for 80.89%. Among the 3241 non-DM patients, 1743 (53.78%) were hypertensive and 1498 (46.22%) were nonhypertensive. The DM group had more cases of HT than did the non-DM group. There were more patients with CHD or CKD in the DM group than in the non-DM group. There were more patients who drank alcohol more frequently (≥ 3 times) in the DM group than in the non-DM group.

CONCLUSION

Older adults in the Lugu community are at a greater risk of DM. In elderly individuals, DM is closely related to high BMI and HT, CHD, and CKD. Physical examinations should be actively carried out for elderly people to determine their BMI, SBP, DBP, and other signs, and sufficient attention should be given to abnormalities in the above signs before further diagnosis.

Is recovery enhancement after gastric cancer surgery really a safe approach for elderly patients?

BACKGROUND

This study aimed to evaluate the safety of enhanced recovery after surgery (ERAS) in elderly patients with gastric cancer (GC).

AIM

To evaluate the safety of ERAS in elderly patients with GC.

METHODS

The PubMed, EMBASE, and Cochrane Library databases were used to search for eligible studies from inception to April 1, 2023. The mean difference (MD), odds ratio (OR) and 95% confidence interval (95%CI) were pooled for analysis. The quality of the included studies was evaluated using the Newcastle-Ottawa Scale scores. We used Stata (V.16.0) software for data analysis.

RESULTS

This study consists of six studies involving 878 elderly patients. By analyzing the clinical outcomes, we found that the ERAS group had shorter postoperative hospital stays (MD = -0.51, I² = 0.00%, 95%CI = -0.72 to -0.30, P = 0.00); earlier times to first flatus (defecation; MD = -0.30, I² = 0.00%, 95%CI = -0.55 to -0.06, P = 0.02); less intestinal obstruction (OR = 3.24, I² = 0.00%, 95%CI = 1.07 to 9.78, P = 0.04); less nausea and vomiting (OR = 4.07, I² = 0.00%, 95%CI = 1.29 to 12.84, P = 0.02); and less gastric retention (OR = 5.69, I² = 2.46%, 95%CI = 2.00 to 16.20, P = 0.00). Our results showed that the conventional group had a greater mortality rate than the ERAS group (OR = 0.24, I² = 0.00%, 95%CI = 0.07 to 0.84, P = 0.03). However, there was no statistically significant difference in major complications between the ERAS group and the conventional group (OR = 0.67, I² = 0.00%, 95%CI = 0.38 to 1.18, P = 0.16).

CONCLUSION

Compared to those with conventional recovery, elderly GC patients who received the ERAS protocol after surgery had a lower risk of mortality.

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.

Comparative study of laparoscopic ventral mesh rectopexy versus perineal stapler resection for external full-thickness rectal prolapse in elderly patients: enhanced outcomes and reduced recurrence rates-a retrospective cohort study

BACKGROUND

In elderly patients with external full-thickness rectal prolapse (EFTRP), the exact differences in postoperative recurrence and functional outcomes between laparoscopic ventral mesh rectopexy (LVMR) and perineal stapler resection (PSR) have not yet been investigated.

METHODS

We conducted a retrospective multicenter study on 330 elderly patients divided into LVMR group (n = 250) and PSR (n = 80) from April 2012 to April 2019. Patients were evaluated before and after surgery by Wexner incontinence scale, Altomare constipation scale, and patient satisfaction questionnaire. The primary outcomes were incidence and risk factors for EFTRP recurrence. Secondary outcomes were postoperative incontinence, constipation, and patient satisfaction.

RESULTS

LVMR was associated with fewer postoperative complications (p < 0.001), lower prolapse recurrence (p < 0.001), lower Wexner incontinence score (p = 0.03), and lower Altomare's score (p = 0.047). Furthermore, LVMR demonstrated a significantly higher surgery-recurrence interval (p < 0.001), incontinence improvement (p = 0.019), and patient satisfaction (p < 0.001) than PSR. Three and 13 patients developed new symptoms in LVMR and PSR, respectively. The predictors for prolapse recurrence were LVMR (associated with 93% risk reduction of recurrence, OR 0.067, 95% CI 0.03-0.347, p = 0.001), symptom duration (prolonged duration was associated with an increased risk of recurrence, OR 1.131, 95% CI 1.036-1.236, p = 0.006), and length of prolapse (increased length was associated with a high recurrence risk (OR = 1.407, 95% CI = 1.197-1.655, p < 0.001).

CONCLUSIONS

LVMR is safe for EFTRP treatment in elderly patients with low recurrence, and improved postoperative functional outcomes.

Risk factors of different mortality periods in older patients with end-stage renal disease undergoing urgent-start peritoneal dialysis: a retrospective observational study

BACKGROUND

The first six months of therapy represents a high-risk period for peritoneal dialysis (PD) failure. The risk of death in the first six months is higher for older patients treated with urgent-start PD (USPD). However, there are still gaps in research on mortality and risk factors for death in this particular group of patients. We aimed to investigate mortality rates and risk factors for death in older patients with end-stage renal disease (ESRD) receiving USPD within and after six months of therapy.

METHODS

We retrospectively studied the clinical information of older adults aged ≥ 65 years with ESRD who received USPD between 2013 and 2019 in five Chinese hospitals. Patients were followed up to June 30, 2020. The mortality and risk factors for death in the first six months of USPD treatment and beyond were analyzed.

RESULTS

Of the 379 elderly patients in the study, 130 died over the study period. During the follow-up period, the highest number (45, 34.6%) of deaths occurred within the first six months. Cardiovascular disease was the most common cause of death. The baseline New York Heart Association (NYHA) class III-IV cardiac function [hazard ratio (HR) = 2.457, 95% confidence interval (CI): 1.200-5.030, p = 0.014] and higher white blood cell (WBC) count (HR = 1.082, 95% CI: 1.021-1.147, p = 0.008) increased the mortality risk within six months of USPD. The baseline NYHA class III-IV cardiac function (HR = 1.945, 95% CI: 1.149-3.294, p = 0.013), lower WBC count (HR = 0.917, 95% CI: 0.845-0.996, p = 0.040), lower potassium levels (HR = 0.584, 95% CI: 0.429-0.796, p = 0.001), and higher calcium levels (HR = 2.160, 95% CI: 1.025-4.554, p = 0.043) increased the mortality risk after six months of USPD.

CONCLUSION

Different risk factors correlated with mortality in older adults with ESRD within and after six months of undergoing USPD, including baseline NYHA class III-IV cardiac function, WBC count, potassium, and calcium levels.

Predictive health monitoring: Leveraging artificial intelligence for early detection of infectious diseases in nursing home residents through discontinuous vital signs analysis

This research addresses the problem of detecting acute respiratory, urinary tract, and other infectious diseases in elderly nursing home residents using machine learning algorithms. The study analyzes data extracted from multiple vital signs and other contextual information for diagnostic purposes. The daily data collection process encounters sampling constraints due to weekends, holidays, shift changes, staff turnover, and equipment breakdowns, resulting in numerous nulls, repeated readings, outliers, and meaningless values. The short time series generated also pose a challenge to analysis, preventing the extraction of seasonal information or consistent trends. Blind data collection results in most of the data coming from periods when residents are healthy, resulting in excessively imbalanced data. This study proposes a data cleaning process and then builds a mechanism that reproduces the basal activity of the residents to improve the classification of the disease. The results show that the proposed basal module-assisted machine learning techniques allow anticipating diagnostics 2, 3 or 4 days before doctors decide to start treatment with antibiotics, achieving a performance measured by the area-under-the-curve metric of 0.857. The contributions of this work are: (1) a new data cleaning process; (2) the analysis of contextual information to improve data quality; (3) the generation of a baseline measure for relative comparison; and (4) the use of either binary (disease/no disease) or multiclass classification, differentiating among types of infections and showing the advantages of multiclass versus binary classification. From a medical point of view, the anticipated detection of infectious diseases in institutionalized individuals is brand new.

Clinical outcomes of clostridioides difficile infection in the very elderly

BACKGROUND

Clostridioides difficile infection (CDI) causes considerable morbidity, mortality, and economic cost. Advanced age, prolonged stay in healthcare facility, and exposure to antibiotics are leading risk factors for CDI. Data on CDI clinical outcomes in the very elderly patients are limited.

METHODS

A retrospective cohort study of patients hospitalized between 2016 and 2018 with CDI. We evaluated demographic clinical and laboratory parameters. Major clinical outcomes were evaluated including duration of hospital stay, admission to intensive care unit (ICU), in-hospital mortality, 30 days post-discharge mortality, and readmission/mortality composite outcome. We compared patients aged up to 80 years (elderly) to those of 80 years old or more (very elderly).

RESULTS

Of 196 patients included in the study, 112 (57%) were very elderly with a mean age of 86 versus 67 years in the elderly group. The duration of hospital stays, and intensive care unit admission frequency were significantly reduced in the very elderly (13 vs. 22 days p = 0.003 and 1.8% vs. 10.7% p = 0.01, respectively). No significant difference was found in the frequencies of in-hospital and in 30 days post-discharge mortality.

CONCLUSIONS

In our cohort, the duration of hospital stay seemed to be shorter in the very elderly with no increase of in-hospital and post-discharge mortality. Although admitted less frequently to ICU, the in-hospital survival of the very elderly was not adversely affected compared to the elderly, suggesting that very advanced age per se should not be a major factor to consider in determining the prognosis of a patient with CDI.

Prognostic impact of muscle mass loss in elderly patients with oesophageal cancer receiving neoadjuvant chemoradiation therapy

BACKGROUND

We aimed to identify the impact of muscle mass on locally advanced oesophageal cancer (LAEC) in elderly patients receiving neoadjuvant chemoradiation therapy (NACRT).

METHODS

We reviewed the medical records of 345 patients diagnosed with LAEC who underwent NACRT and surgery. Physical variables, including height, weight, skeletal muscle mass, and laboratory values, were obtained before and after NACRT. Body mass index (BMI, kg/m2), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and prognostic nutritional index (PNI) were calculated as height/(weight)2, ANC/ALC, platelet count/ALC, and (10 × albumin + 0.05 × ALC), respectively. The cutoff for low muscle mass was 43.0 cm2/m2 for BMI below 25 kg/m2 and 53.0 cm2/m2 for BMI 25 kg/m2 or higher. The skeletal muscle index (SMI) was defined as skeletal muscle area/(height)2 (cm2/m2). The ΔSMI (%/50 days) was defined as (SMI after NACRT - SMI before NACRT)/interval (days) × 50 (days) to compare changes over the same period. The excessive muscle loss (EML) group was defined as patients with ΔSMI ≤-10% following NACRT. An elderly patient was defined as aged ≥65 years. The primary outcome measure was overall survival (OS).

RESULTS

During a median follow-up of 32.8 months (range, 2.0-176.2), 192 patients died, with a median OS of 50.2 months. Elderly patients did not show inferior OS (young vs. elderly, 57.7% vs. 54.0% at 3 years, P = 0.247). 71.0% and 87.2% of all patients had low muscle mass before and after NACRT, respectively, which was not associated with OS (P = 0.270 and P = 0.509, respectively). Inflammatory (NLR and PLR) and nutritional index (PNI) values or their changes did not correlate with OS. However, the EML group had worse OS (41.6% vs. 63.2% at 3 years, P < 0.0001). In the multivariate analysis, EML was also a significant prognostic factor for OS. In the subgroup analysis by age, EML was a strong prognostic factor for OS in the elderly group. The 3-year OS was 36.8% in the EML group and 64.9% in the non-EML group (P < 0.0001) in elderly patients, and 47.4% and 62.1% (P = 0.063) in the young patients. In multivariate analysis of each subgroup, EML remained prognostic only in the elderly group (P = 0.008).

CONCLUSIONS

EML may be strongly associated with a deteriorated OS in elderly patients undergoing NACRT, followed by surgery for LAEC. The strategies for decreasing muscle loss in these patients should be investigated.

Health economic evaluation of blended collaborative care for older multimorbid heart failure patients: study protocol

BACKGROUND

Integrated care, in particular the 'Blended Collaborative Care (BCC)' strategy, may have the potential to improve health-related quality of life (HRQoL) in multimorbid patients with heart failure (HF) and psychosocial burden at no or low additional cost. The ESCAPE trial is a randomised controlled trial for the evaluation of a BCC approach in five European countries. For the economic evaluation of alongside this trial, the four main objectives were: (i) to document the costs of delivering the intervention, (ii) to assess the running costs across study sites, (iii) to evaluate short-term cost-effectiveness and cost-utility compared to providers' usual care, and (iv) to examine the budgetary implications.

METHODS

The trial-based economic analyses will include cross-country cost-effectiveness and cost-utility assessments from a payer perspective. The cost-utility analysis will calculate quality-adjusted life years (QALYs) using the EQ-5D-5L and national value sets. Cost-effectiveness will include the cost per hospital admission avoided and the cost per depression-free days (DFD). Resource use will be measured from different sources, including electronic medical health records, standardised questionnaires, patient receipts and a care manager survey. Uncertainty will be addressed using bootstrapping.

DISCUSSION

The various methods and approaches used for data acquisition should provide insights into the potential benefits and cost-effectiveness of a BCC intervention. Providing the economic evaluation of ESCAPE will contribute to a country-based structural and organisational planning of BCC (e.g., the number of patients that may benefit, how many care managers are needed). Improved care is expected to enhance health-related quality of life at little or no extra cost.

TRIAL REGISTRATION

The study follows CHEERS2022 and is registered at the German Clinical Trials Register (DRKS00025120).

Ambient heat exposure patterns and emergency department visits and hospitalizations among medicare beneficiaries 2008-2019

OBJECTIVE

To assess the association between ambient heat and all-cause and cause-specific emergency department (ED) visits and acute hospitalizations among Medicare beneficiaries in the conterminous United States.

DESIGN

Retrospective cohort study.

SETTING

Conterminous US from 2008 and 2019.

PARTICIPANTS

2% random sample of all Medicare fee-for-service beneficiaries eligible for Parts A, B, and D.

MAIN OUTCOME MEASURES

All-cause and cause-specific (cardiovascular, renal, and heat-related) ED visits and unplanned hospitalizations were identified using primary ICD-9 or ICD-10 diagnosis codes. We measured the association between ambient temperature - defined as daily mean temperature percentile of summer (June through September) - and the outcomes. Hazard ratios and their associated 95% confidence intervals were estimated using multivariable Cox proportional hazards regression, adjusting for individual level demographics, comorbidities, healthcare utilization factors and zip-code level social factors.

RESULTS

Among 809,636 Medicare beneficiaries (58% female, 81% non-Hispanic White, 24% <65), older beneficiaries (aged ≥65) exposed to >95th percentile temperature had a 64% elevated adjusted risk of heat-related ED visits (HR [95% CI], 1.64 [1.46,1.85]) and a 4% higher risk of all-cause acute hospitalization (1.04 [1.01,1.06]) relative to <25th temperature percentile. Younger beneficiaries (aged <65) showed increased risk of heat-related ED visits (2.69 [2.23,3.23]) and all-cause ED visits (1.03 [1.01,1.05]). The associations with heat related events were stronger in males and individuals dually eligible for Medicare and Medicaid. No significant differences were observed by climatic region. We observed no significant relationship between temperature percentile and risk of CV-related ED visits or renal-related ED visits.

CONCLUSIONS

Among Medicare beneficiaries from 2008 to 2019, exposure to daily mean temperature ≥ 95th percentile was associated with increased risk of heat-related ED visits, with stronger associations seen among beneficiaries <65, males, and patients with low socioeconomic position. Further longitudinal studies are needed to understand the impact of heat duration, intensity, and frequency on cause-specific hospitalization outcomes.

Risk factors for bariatric surgery in patients over 65 years of age-a multicenter retrospective cohort study

PURPOSE

Societies are aging, life expectancy is increasing, and as a result, the percentage of elderly people in the population is constantly increasing. When qualifying patients over 65 years of age for bariatric surgery, the benefits and risks should be carefully assessed. Weighing risk factors against each other to improve the quality of life and better control of obesity-related diseases. The study aimed to determine risk factors for bariatric surgery among patients over 65 years of age.

METHODS

A multicenter, retrospective analysis of patients undergoing laparoscopic bariatric procedures from 2008 to 2022. The patients were divided into two groups: complicated (C) and uncomplicated (UC). Uni- and multivariate logistic regression analysis was performed to obtain significant, independent risk factors.

RESULTS

There were 20 (7.0%) patients in C group and 264 (93.0%) patients in UC group. The most common complication was intraperitoneal bleeding (8, 2.8). There was no postoperative mortality. The mean follow-up was 47.5 months. In a multivariate logistic regression analysis, length of stay and %EWL significantly corresponded to general complications (OR 1.173, OR 1.020). A higher weight loss before surgery lowered the risk for hemorrhagic events after surgery (OR 0.889). A longer length of stay corresponded to leak after surgery (OR 1.175).

CONCLUSIONS

Bariatric and metabolic surgery appears to be a safe method of obesity treatment in patients over 65 years of age. The most common complication was intraperitoneal bleeding. A prolonged hospital stay may increase the risk of leakage, while a higher weight loss before the surgery may lower the risk of bleeding.

Risk factors for clinically important traumatic brain injury in minor head injury in older people

BACKGROUND AND OBJECTIVES

The incidence of traumatic brain injury (TBI) in older individuals is increasing with an increase in the older population. For older people, the required medical interventions and hospitalization following minor head injury have negative impacts, which have not been reported in literature up till now. We aimed to investigate the risk factors for clinically important traumatic brain injury (ciTBI) in older patients with minor head injury.

METHODS

This is a retrospective single-center cohort study. Older patients aged ≥65 years presenting with head injury and a Glasgow Coma Scale (GCS) score of ≥13 upon arrival at the hospital between January 1, 2018, and October 31, 2021, were included. Patients with an injury duration of ≥24 h were excluded. The primary outcome was defined as ciTBI (including death, surgery, intubation, medical interventions, and hospital stays of ≥2 nights). Multiple logistic regression analysis was conducted to identify the risk factors.

RESULTS

A total of 296 patients were included initially, and 6 of them were excluded subsequently. ciTBI was identified in 62 cases. According to the results of the multiple logistic regression analysis, GCS scores of ≤14 (OR 3.72, 95% CI 1.89-7.30), high-risk mechanisms of injury (OR 2.80, 95% CI 1.39-5.64), vomiting (OR 5.01, 95% CI 1.19-21.1), and retrograde amnesia (OR 6.90, 95% CI 3.37-14.1) were identified as risk factors.

CONCLUSION

In older patients with minor head injury, GCS ≤14, high-risk mechanisms of injury, vomiting, and retrograde amnesia are risk factors for ciTBI.

[Traumatic brain injury in patients over 65 years of age attended in the emergency department, characteristics and complications]

BACKGROUND AND OBJECTIVE

Ageing is associated with an increased risk of falls and trauma. The aim of the study was to assess the characteristics of patients over 65 years of age who consulted the ED for traumatic brain injury (TBI) in 2022, their relationship with cognitive impairment, functional dependence, use of oral antiplatelet/anticoagulant drugs and complications.

MATERIALS AND METHODS

Retrospective study conducted from 1 January to 31 December 2022. Demographic data were collected: age, sex, origin; cardiovascular risk factors; cognitive impairment using the Pfeiffer questionnaire; physical disability according to the Barthel Index; number of drugs; use of antiplatelet and oral anticoagulant (OAC); mechanism of fall; performance of cranial X-ray/CT, and presence of complications: intracranial haemorrhage (ICH), death.

RESULTS

599 patients were included. The mean age was 82.3±8.2 years. 63.8% were female and 36.2% male. 75.3% were from home, 24.7% from residence. No dementia in 61.4%, moderate-severe dementia in 38.6%. 58.1% were functionally independent, 25.1% had moderate-severe dependence. 85.7% had CVRF: HT 476 (79.5%), dyslipidaemia 354 (59.1%), DM 217 (36.2%), obesity 173 (28.9%), smoking 15 (2.5%). The number of drugs per patient was 9.2±4.3. Polypharmacy was present in 94.7% of patients. 35.9% were taking antiplatelet drugs and 30.2% anticoagulants. Intracranial haemorrhage occurred in 11 (2.3%) patients. Four (0.7%) patients died.

CONCLUSIONS

The TBI in our study was caused by low-energy trauma in a female patient, without dementia, functionally independent and with polypharmacy. There were few serious complications: 2.3% ICH and 0.7% deaths. 90.1% of ICH occurred in patients on antiplatelet and/or OAC therapy.

Gender-specific link between sleep quality and body composition components: a cross-sectional study on the elderly

Sleep duration has been associated with overweight/obesity. Since sleep quality and body composition alter during aging, we conducted this study to determine if sleep quality is linked to body composition components in elderly people. This is a cross-sectional study conducted on 305 Iranian community-dwelling elderly aged ≥ 65 years. Sleep quality and body composition components were evaluated using Pittsburgh sleep quality index and bioelectric impedance analysis, respectively. The association of sleep quality and body composition components was examined using linear regression analysis. The prevalence of poor sleep quality and overweight/obesity was 48.9% and 54.4% in men and 77.0% and 79.3% in women, respectively. Women had significantly higher scores in most PSQI items than men, indicating their worse sleep quality compared to men. Women also had significantly higher body mass index (BMI), body fat percentage, and visceral adipose tissue and lower skeletal muscle and fat-free mass percentages than men. In the adjusted regression model, men showed positive associations between the third tertile of poor sleep quality and BMI (B = 1.35; 95% CI 0.08-2.61) and waist circumference (B = 4.14; 95% CI 0.39-7.89), but they did not demonstrate an association between sleep quality and body composition components. In the adjusted regression model for women, there were positive associations for BMI (B = 1.21; 95% CI 0.34-2.07), waist circumference (B = 2.95; 95% CI 0.99-4.91), body fat percentage (B = 2.75; 95% CI 1.06-4.45), and visceral adipose tissue (B = 7.80; 95% CI 1.73-13.87); also there were negative associations for skeletal muscle (B =  - 1.40; 95% CI - 2.39 - - 0.41) and fat-free mass (B =  - 2.76; 95% CI - 4.46 - -1.07) percentages. Except for waist circumference, other variables differed between men and women (P < 0.001). Weight management, prevention of muscle wasting, and improvement of sleep quality should be considered in a consortium when designing healthcare strategies for the elderly.

Biomechanics of the lower limb in patients with mild knee osteoarthritis during the sit-to-stand task

BACKGROUND

Knee osteoarthritis (KOA) is a prevalent and debilitating condition that markedly affects the sit-to-stand (STS) activity of patients, a prerequisite for daily activities. Biomechanical recognition of movements in patients with mild KOA is currently attracting attention. However, limited studies have been conducted solely on the observed differences in sagittal plane movement and muscle activation.

AIM

This study aimed to identify three-dimensional biomechanical and muscle activation characteristics of the STS activity in patients with mild KOA.

METHODS

A cross-sectional study was conducted to observe the differences between patients with mild KOA and a control group (CG). It was conducted to observe the differences in muscle activation, including root mean square (RMS%) and integrated electromyography (items), kinematic parameters like range of motion (ROM) and maximum angular velocity, as well as dynamic parameters such as joint moment and vertical ground reaction force (vGRF).

RESULTS

Patients with mild KOA had a higher body mass index and longer task duration. In the sagittal plane, patients with KOA showed an increased ROM of the pelvic region, reduced ROM of the hip-knee-ankle joint, and diminished maximum angular velocity of the knee-ankle joint. Furthermore, patients with KOA displayed increased knee-ankle joint ROM in the coronal plane and decreased ankle joint ROM in the horizontal plane. Integrated vGRF was higher in both lower limbs, whereas the vGRF of the affected side was lower. Furthermore, patients showed a decreased peak adduction moment (PADM) and increased peak external rotation moment in the knee joint and smaller PADM and peak internal rotation moment in the ankle joint. The affected side exhibited decreased RMS% and iEMG values of the gluteus medius, vastus medialis, and vastus lateralis muscles, as well as a decreased RMS% of the rectus femoris muscle. Conversely, RMS% and iEMG values of the biceps femoris, lateral gastrocnemius, and medial gastrocnemius muscles were higher.

CONCLUSION

The unbalanced activation characteristics of the anterior and posterior muscle groups, combined with changes in joint moment in the three-dimensional plane of the affected joint, may pose a potential risk of injury to the irritated articular cartilage.

New surgery and hospital-diagnosed infections in elderly patients with inflammatory bowel disease undergoing surgery - a nationwide cohort study

BACKGROUND

Elderly patients with inflammatory bowel disease (IBD) are fragile in many aspects. Therefore, in these patients, we studied post-operative complications (new abdominal surgery and serious infections after the first IBD surgery).

METHODS

This is a nationwide cohort study based on Danish health registries and included patients with IBD undergoing surgery. The study population was split into ulcerative colitis (UC) and Crohn's disease (CD). The exposed cohort (elderly) constituted those at an age of ≥ 60 years at first IBD surgery, and the unexposed (adults) those with surgery at the age of 18-59 years. We estimated adjusted Hazard Ratios (aHR) of a) new abdominal surgery within 2 years, and b) serious (hospital-diagnosed) infections within 6 and 12 months. We adjusted for several confounders including type of index surgery (laparoscopic or open).

RESULTS

The aHR for a new surgery among elderly with UC and CD were 0.69 (95% CI 0.58-0.83) and 0.98 (95% CI 0.83-1.15), respectively. In elderly with UC, the aHRs of infections within 6 and 12 months after surgery were 1.07 (95% CI 0.81- 1.40) and 0.85 (95% CI 0.67-1.08), respectively. In the elderly with CD, the aHRs of infections within 6 and 12 months were 1.45 (95% CI 1.12-1.88) and 1.26 (95% CI 1.00-1.59), respectively.

CONCLUSION

The elderly with IBD did not have an increased risk of new abdominal surgery within two years of the first surgery. Elderly with CD, but not UC, had an increased risk of serious infections within 6 months of surgery.

Comparison of laparoscopic and open inguinal-hernia repair in elderly patients: the experience of two comprehensive medical centers over 10 years

PURPOSE

The safety of laparoscopic inguinal-hernia repair must be carefully evaluated in elderly patients. Very little is known regarding the safety of the laparoscopic approach in elderly patients under surgical and medical co-management (SMC). Therefore, this study evaluated the safety of the laparoscopic approach in elderly patients, especially patients with multiple comorbidities under SMC.

METHODS

From January 2012 to December 2021, patients aged ≥ 65 years who underwent open or laparoscopic inguinal-hernia repair during hospitalization were consecutively enrolled. Postoperative outcomes included major and minor operation-related complications, and other adverse events. To reduce potential selection bias, propensity score matching was performed between open and laparoscopic groups based on patients' demographics and comorbidities.

RESULTS

A total of 447 elderly patients who underwent inguinal-hernia repair were enrolled, with 408 (91.3%) underwent open and 39 (8.7%) laparoscopic surgery. All postoperative outcomes were comparable between open and laparoscopic groups after 1:1 propensity score matching (all p > 0.05). Moreover, compared to the traditional care group (n = 360), a higher proportion of the SMC group (n = 87) was treated via the laparoscopic approach (18.4% vs. 6.4%, p = 0.00). In the laparoscopic approach subgroup (n = 39), patients in the SMC group (n = 16) were older with multiple comorbidities but were at higher risks of only minor operation-related complications, compared to those in the traditional care group.

CONCLUSIONS

Laparoscopic inguinal-hernia repair surgery is safe for elderly patients, especially those with multiple comorbidities under SMC.

The use of uncemented stems in femoral neck fractures in elderly patients: A comparative study of 671 cases

INTRODUCTION

The use of cemented stems in elderly patients is associated with the risk of intraoperative embolic complications. Uncemented stems eliminate this risk, but their use is controversial because of the risk of mechanical complications, with estimated subsidence between 3.6 and 30% and periprosthetic fractures between 2.1 and 11% at 6 weeks. A retrospective multicenter comparative study was conducted using a propensity score analysis to evaluate mechanical performances of uncemented stems in femoral neck fractures in elderly patients to (1) compare the risk of mechanical complications and (2) assess the use of metaphyseal-anchored stems for this indication.

HYPOTHESIS

There is no difference in the risk of mechanical complications, intraoperatively or postoperatively, between these stems.

MATERIALS AND METHODS

We conducted a multicenter retrospective comparative study including 358 uncemented and 313 cemented stems. The mean age was 84.5 years [83.9-85.1]. The inclusion criteria were patients 70 years and older and a follow-up of at least 6 weeks. The primary endpoint was a composite endpoint comprised of stem subsidence≥2mm or periprosthetic fracture (up to 3 months postoperatively). The secondary endpoints were infection, stem subsidence≥2mm, and operative time. These endpoints were analyzed using a propensity score to control confounding factors. A secondary analysis used the same endpoints to compare metaphyseal-anchored (short stems) versus Corail-like stems.

RESULTS

After adjusting for the propensity score, we found 11.17% mechanical complications in the uncemented group (n=40, 5.59% subsidence, and 5.59% fractures) versus 13.42% for the cemented group (n=42, 7.99% subsidence, and 5.43% fractures). There was no statistically significant difference between the 2 values (Odds Ratio [OR]=0.64 [95% Confidence Interval [CI]: 0.14-2.85] [p=0.7]). The mortality rate due to cement embolism was 1%. There was no difference in the rate of subsidence (OR=0.55 [95% CI: 0.02-12.5] [p=0.7]), periprosthetic fracture (OR=0.65 [95% CI: 0.13-3.12] [p=0.7]) or infection (OR=0.71 [95% CI: 0.32-1.55] [p=0.4]). However, the operative times were longer in the cemented group (p=0.03 for hemiarthroplasties [mean additional time 16minutes] and p=0.02 for total hip arthroplasties [mean additional time 22minutes]). No difference was observed between the metaphyseal-anchored (short stems) and Corail-like stems regarding operative time, rate of infection, and rate of stem subsidence or periprosthetic fractures.

DISCUSSION

This is one of the first studies to highlight cemented stem subsidence when used for femoral neck fractures in elderly patients. Using uncemented stems in this indication is still warranted, especially since they do not bring about more mechanical complications in the first few months. Metaphyseal-anchored short stems seem to give the same results as "standard" stems. However, these findings need to be assessed in the longer term.
