Association of AST/ALT ratio with 90-day outcomes in patients with acute exacerbation of chronic liver disease: a prospective multicenter cohort study in China

Background and aim

A high aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio is associated with liver injury in liver disease; however, no data exist regarding its relationship with 90-day prognosis in patients with acute exacerbation of chronic liver disease.

Methods

In this study, 3,758 participants (955 with advanced fibrosis and 2,803 with cirrhosis) from the CATCH-LIFE cohort in China were included. The relationships between different AST/ALT ratios and the risk of adverse 90-day outcomes (death or liver transplantation) were determined in patients with cirrhosis or hepatitis B virus (HBV)-associated advanced fibrosis, respectively.

Results

In the patients with HBV-associated advanced fibrosis, the risk of 90-day adverse outcomes increased with AST/ALT ratio; after adjusting for all confounding factors, the risk of adverse 90-day outcomes was the highest when AST/ALT ratio was more than 1.08 (OR = 6.91 [95% CI = 1.789-26.721], p = 0.005), and the AST/ALT ratio of >1.9 accelerated the development of adverse outcomes. In patients with cirrhosis, an AST/ALT ratio > 1.38 increased the risk of adverse 90-day outcomes in all univariables (OR = 1.551 [95% CI = 1.216-1.983], p < 0.001) and multivariable-adjusted analyses (OR = 1.847 [95% CI = 1.361-2.514], p < 0.001), and an elevated AST/ALT ratio (<2.65) accelerated the incidence of 90-day adverse outcomes. An AST/ALT ratio of >1.38 corresponded with a more than 20% incidence of adverse outcomes in patients with cirrhosis.

Conclusion

The AST/ALT ratio is an independent risk factor for adverse 90-day outcomes in patients with cirrhosis and HBV-associated advanced fibrosis. The cutoff values of the AST/ALT ratio could help clinicians monitor the condition of patients when making clinical decisions.

A dyadic session-by-session assessment of therapeutic alliance and short-term outcome among clients with schizophrenia in comparison with clients with emotional disorders

OBJECTIVE

Although the clinical significance of the therapeutic alliance (TA) is well documented, the literature regarding the establishment of TA and the relation between client-therapist agreement on it to short-term outcome among various diagnostic groups-and specifically among clients diagnosed with serious mental illness (SMI)-is sparse. The aim of the present study was to examine the effect of client diagnosis on the abovementioned TA characteristics.

METHOD

Dyadic analyses of session-by-session (SBS) data were used to compare clients diagnosed with schizophrenia and clients diagnosed with emotional disorders (based on a clinical interview) in their TA characteristics.

RESULTS

TA as initially rated by clients was stronger in the emotional disorders group than in the schizophrenia group. Higher TA ratings, regardless of whether these were provided by the therapist or the client, predicted better subsequent functioning in the emotional disorders group, whereas in the schizophrenia group, this association was observed only among good-outcome cases.

CONCLUSIONS

Establishing TA, having client-therapist agreement on it, and having clients derive therapeutic benefit from it might be more challenging with clients with schizophrenia than with clients with emotional disorders. Special attention should be given to specific challenges and needs regarding clients' diagnosis in order to enhance favourable therapy outcomes.

Total Pelvic Exenteration Combined With Sacral Resection for Rectal Cancer

BACKGROUND

This retrospective study aimed to demonstrate surgical operative approach of total pelvic exenteration combined with sacral resection with rectal cancer and elucidate the relationships between the level of sacral resection and short-term outcomes.

METHODS

Twenty cases were selected. Data regarding sex, age, body mass index, neoadjuvant therapy, location of sacral resection ("Upper" or "Lower" relative to the level between the 3rd and 4th sacral segment), operative time, bleeding, and curability (R0/R1) were collected and compared to determine their association with complications exhibiting a Clavien-Dindo grade III.

RESULTS

The complication rate was significantly higher for recurrent cancers (n = 10, 76.9%) than for primary cancers (n = 1, 14.3%) (P = .007), and for "Upper" resection (n = 8, 72.7%) than for "Lower" resection (n = 3, 33.3%) (P = .078). Significant differences were observed when complication rates for "Lower" and primary cancer resection (n = 3, .0%) were compared between "Upper" and recurrent cancers (n = 8, 100.0%) (P = .007).

CONCLUSION

In patients with recurrent rectal cancer, "Upper" sacral resection during total pelvic exenteration is associated with a high complication rate, highlighting the need for careful monitoring.

Case report: Traumatic hemorrhagic cervical myelopathy in a dog

A 1.5-year-old female entire French bulldog was referred for neurological evaluation, further diagnostic tests, and treatment 24 h after a road traffic accident. Initial emergency treatment, diagnostic tests, and stabilization had been performed by the referring veterinarian. Neurological examination revealed severe spastic non-ambulatory tetraparesis and was consistent with a C1-5 myelopathy. A magnetic resonance imaging (MRI) study revealed an irregular to elongated ovoid intramedullary lesion centered over the body of C2. The lesion showed marked signal heterogeneity with a central T2W and T2* hyperintense region, surrounded by a hypointense rim on both sequences. The lesion appeared heterogeneously T1W hypointense. The lesion was asymmetric (right-sided), affecting both white and gray matter. The C2-3 intervertebral disk appeared moderately degenerate with a Pfirrmann grade of 3. No evidence of vertebral fracture or luxation was found on radiographs or MRI of the vertebral column. Additional soft tissue abnormalities in the area of the right brachial plexus were suggestive of brachial plexus and muscle injury. A diagnosis of traumatic hemorrhagic myelopathy at the level of C2 and concurrent brachial plexus injury was formed. Conservative treatment was elected and consisted of physiotherapy, bladder care with an indwelling urinary catheter, repeated IV methadone based on pain scoring (0.2 mg/kg), oral meloxicam 0.1 mg/kg q24h, and oral gabapentin 10 mg/kg q8h. The dog was discharged after 4 days, with an indwelling urinary catheter and oral medication as described. The catheter was replaced two times by the referring veterinarian and finally removed after 10 days. Thereafter, voluntary urination was seen. During the 2 months after the road traffic accident, slow recovery of motor function was seen. The right thoracic limb recovery progressed more slowly than the left limb, also showing some lower motor neuron signs during follow-up. This was judged to be consistent with a right-sided brachial plexus injury. The dog was reported ambulatory with mild residual ataxia and residual monoparesis of the right thoracic limb at the last follow-up 3 months post-injury. This case report highlights the MRI-based diagnosis of traumatic hemorrhagic myelopathy in a dog. A fair short-term outcome was achieved with conservative treatment in this case.

The Response of Synthetic Adrenocorticotropic Hormone (ACTH) Treatment in Pediatric Drug-Resistant Epilepsy Other Than Infantile Epileptic Spasms Syndrome: A Retrospective Observational Study

INTRODUCTION

 Adrenocorticotropic hormone (ACTH) is a tropic hormone naturally secreted by the anterior pituitary gland to stimulate the secretion of cortisol and androgens. ACTH is used in non-tuberous sclerosis infantile epileptic spasms syndrome (IESS), and it has shown significant, promising results in epilepsy syndromes with possible inflammatory processes. However, many studies have also demonstrated a promising potential even in other types of drug-resistant epilepsy.  Material and method: This study is a retrospective observational study that follows the clinical characteristics and outcomes of nine pediatric patients with drug-resistant epilepsy treated with short-term synthetic ACTH in Saudi Arabia. The response was assessed during the ACTH infusion and after three months.

RESULTS

During infusion, six of the nine (66%) patients had a short-term (within two weeks) favorable response, with a more than 50% reduction in seizure frequency. Four of the nine (44%) patients had complete responses with seizure freedom. After three months, four patients (44%) had a three-month seizure frequency reduction of more than 30% attributed to ACTH, including one patient with an IESS history who had a 70% reduction in seizure frequency. Of the four patients who had a complete response, three (75%) had a seizure relapse after tapering in the following three months.  Conclusion: This case series adds to the literature to suggest ACTH treatment of drug-resistant epilepsies other than IESS might benefit some patients in the acute setting but they are less likely to maintain a sustained treatment response. Randomized and large sample size studies are necessary to assess treatment response and accurately aid in appropriate patient selection.

Surgeon's Experience May Circumvent Operative Volume in Improving Early Outcomes After Pancreaticoduodenectomy

Introduction Pancreaticoduodenectomy (PD) is a complex procedure with a significant proportion of postoperative complications and improving but notable mortality. PD was the prototype procedure that initiated the lingering debate about the relationship of better operative outcomes when performed at higher-volume centers. This has not translated into practice. Impediments include the absence of a universally accepted definition of a high-volume center among others. Contrary evidence suggests equivalent outcomes for PD at low-volume centers when performed by experienced hepatobiliary surgeons. We reviewed our perioperative outcomes for PD from an earlier period as a low-volume center with an experienced team. Methods A longitudinal study of all PDs completed in our department between 2012 and 2017 was performed. Results A total of 28 PD were performed during this period. Pylorus-preserving PD was performed in 23 patients and classical PD in the remaining. A separate Roux-en-Y loop was used for high-risk pancreatic anastomosis in six cases. The mean patient age was 49.3±12.4 years. The male-to-female ratio was 1.3:1. Preoperative drainage procedures were carried out in 19 patients. The mean serum total bilirubin level was 3.98(±4.5) mg/dL. There was no 90-day mortality. Postoperative complications included wound infection in 10 (36.7%) and respiratory complications in 10 (36.7%) patients. Postoperative bleeding requiring intervention occurred in one patient, and two patients had an anastomotic leak (one pancreatojejunostomy (PJ) and one gastrojejunostomy (GJ)). Delayed gastric emptying (DGE) was noted in three (10.7%) patients. The mean length of hospital stay was 14±7 days. The median overall survival (OS) was 84 months. Conclusion Comparable early outcomes can be achieved at low-volume centers for patients undergoing PD with an experienced team, optimal patient selection, and the ability to rescue for complications.

Distal Tibiofibular Joint Reconstruction Using Autograft in a Rare Case of Lower Limb Sclerosing/Spindle Cell Rhabdomyosarcoma: A Two-Year Follow-Up

Sclerosing/spindle cell rhabdomyosarcoma (s-scRMS) is a rare variant of striated muscle tumours. It has been recognised as an individual entity, the fourth subtype of rhabdomyosarcoma in the latest WHO classification. In the paediatric population, it occurs more commonly in the paratesticular area, whereas in adults, it occurs more commonly in the head and neck region. It has distinctive characteristics in terms of its histopathological and immunochemistry findings, which help in accurate diagnosis. The mainstay of treatment is a multimodal approach, i.e., surgery, chemotherapy, and radiation therapy. However, no standard care is still being established internationally for adult cases. In adults, this tumour has a poorer prognosis as compared to children. We describe a patient with s-scRMS of the lower limb who has undergone wide local resection of the tumour with surgical reconstruction of the distal tibiofibular joint with autograft and its two-year outcome.

Differences in Demographics, in-Hospital Management and Short-Term Prognosis in Admissions for Acutely Decompensated Heart Failure to Cardiology vs. Internal Medicine Departments: A Prospective Study

Heart failure (HF) is among the leading causes of unplanned hospital admissions worldwide. Patients with HF carry a high burden of comorbidities; hence, they are frequently admitted for non-cardiac conditions and managed in Internal Medicine Departments (IMD). The aim of our study was to investigate differences in demographics, in-hospital management, and short-term outcomes of HF patients admitted to IMD vs. cardiology departments (CD). A prospective cohort study enrolling consecutive patients with acutely decompensated HF either as primary or as secondary diagnosis during the index hospitalization was conducted. Our primary endpoint was a combined endpoint of in-hospital mortality and 30-day rehospitalization for HF. A total of 302 patients participated in the study, with 45% of them admitted to IMD. Patients managed by internists were older with less pronounced HF symptoms on admission. In-hospital mortality was higher for patients admitted to IMD vs. CD (21% vs. 6%, p < 0.001). The composite endpoint of in-hospital death and heart failure hospitalizations at 30 days post-discharge was higher for patients admitted to IMD both in univariate [OR: 3.2, 95% CI (1.8-5.7); p < 0.001] and in multivariate analysis [OR 3.74, 95% CI (1.72-8.12); p = 0.001]. In addition, the HF rehospitalization rate at 6 months after discharge was higher in IMD patients [HR 1.65, 95% CI (1.1, 2.4), p = 0.01]. Overall, HF patients admitted to IMD have worse short-term outcomes compared to patients admitted to CD.

Short-term outcomes of robotic lobectomy versus video-assisted lobectomy in patients with pulmonary neoplasms

BACKGROUND

To explore whether robotic lobectomy (RL) is superior to video-assisted lobectomy (VAL) in terms of short-term outcomes in patients with pulmonary neoplasms.

METHODS

From January 30, 2019 to February 28, 2022, a series of consecutive minimally invasive lobectomies were performed for patients with pulmonary neoplasms. Perioperative outcomes such as operation time, blood loss, dissected lymph nodes (LNs), surgical complications, postoperative pain control, length of postoperative stay in hospital, and total cost of hospitalization were compared.

RESULTS

A total of 336 cases including 173 RLs and 163 VALs were enrolled. Baseline characteristics were comparable between groups. RLs were associated with shorter operation time (median [interquadrant range, IQR], 107 min [90-130] vs. 120 min [100-149], p < 0.001), less blood loss (median [IQR], 50 mL [30-60] vs. 50 mL [50-80], p = 0.02), and lower blood transfusion rate (3.5% vs. 9.8%, p = 0.02) compared with VALs. More LNs were harvested by the robotic approach (median [IQR], 29 [20-41] vs. 22 [15-45], p = 0.04). The incidences of conversion, major postoperative complications, extra analgesic usage, and postoperative length of stay were all comparable between the RL and VAL groups. As predicted, the total cost of hospitalization was greater in the RL group (median [IQR], $16728.35 [15682.16-17872.15] vs. $10713.47 [9662.13-11742.15], p < 0.001).

CONCLUSION

RL improved surgical efficacy with shortened operative time, less blood loss, and more thorough LN dissection compared with VAL, compromised by higher cost.

First RAND-36-Item Health Survey in Three-dimensional Laparoscopy Cholecystectomy: A Prospective Randomized Study

BACKGROUND/AIM

National healthcare organizers require feedback from patients to improve medical treatment methods. Three-dimensional laparoscopy cholecystectomy (3D-LC) is a modern technique in surgery. However, there are no studies with patient feedback from validated questionnaires assessing the postoperative treatment results in 3D-LC.

PATIENTS AND METHODS

Initially 200 patients with symptomatic cholelithiasis were randomized into 3D-LC or mini-laparotomy cholecystectomy (MC) groups. RAND-36-Item Health Survey was performed preoperatively and 4 weeks following surgery relating the survey scores between the 3D-LC and MC groups.

RESULTS

Similar postoperative RAND-36 scores were reported for both groups preoperatively and at 4 weeks following surgery, and no significant differences in RAND-36 domains were shown. When the patients in both study groups were combined, Mental Health (p<0.001), Bodily Pain (p=0.01) and General Health (p=0.016) domain scores were significantly higher, indicating a significantly positive change in quality of life 4 weeks postoperatively, while those for the Role-Physical domain were significantly lower, indicating reduced physical activity during the 4 weeks following surgery. In comparison to the Finnish reference RAND-36 scores, scores at 4 weeks were significantly higher for the Mental Health domain (MC group, p<0.001 and 3D-LC group, p=0.001) whilst scores were significantly lower in four other domains: Physical Functioning, Social Functioning, Bodily Pain and Role-Physical.

CONCLUSION

This study shows, for the first time using the RAND-36-Item Health Survey, relatively similar short-term outcomes in patients 4 weeks following cholecystectomy by 3D-LC and MC. Although scores for three RAND-36 domains were significantly higher postoperatively, indicating a significantly positive change in quality of life, a longer follow-up after cholecystectomy is needed for final conclusions to be drawn.

Real-world evidence of safety and influence for lung cancer surgery under COVID-19 pandemic in Japan

Background

The COVID-19 pandemic has affected the clinical practice of lung cancer surgery in Japan, but few studies have revealed the real situation of surgical practice for lung cancer in this country. This latest information will help us to decide the future direction of lung cancer surgery under pandemic circumstances.

Methods

We collected data from patients with primary lung cancer who underwent thoracic surgery between 2018 and 2021. To investigate the impact of the COVID-19 pandemic on lung cancer surgery, we compared between 2018-2019 (prepandemic group) and 2020-2021 (pandemic group) in the respect of patient characteristics, pathological findings, and short-term outcome after lung cancer resection by Mann-Whitney and Fisher's exact tests. Moreover, the monthly number of surgeries for lung cancer in our institution during 2020-2021 was compared with the number of newly diagnosed COVID-19 patients in Japan by Spearman correlation analysis.

Results

From 2018 through 2021, 936 patients with primary lung cancer underwent surgical intervention in our institute and were included in this study. The number of surgeries did not decrease in the pandemic group (n=443) compared with that in the prepandemic group (n=493). Tumor and invasive size in stage I which was measured by pathologist were significantly larger in the pandemic group than in the prepandemic group (tumor size: P=0.031, invasive size: P<0.001). In terms of postoperative short-term outcome, the median hospital stay was 6 days, 30-day mortality was 2, and morbidity was around 20% in both groups. Only one patient suffered from COVID-19 infection 5 months after right upper lobectomy. An increased ratio of newly diagnosed COVID-19 cases in Japan was negatively correlated with the number of surgeries for lung cancer in our institution in the next month (r=-0.393, P=0.007), although there was no correlation in the present or the month after next.

Conclusions

Even during the COVID-19 pandemic period, lung cancer surgery could be performed safely and in a sustainable manner. However, pathological findings of lung cancer tended to be progressive in early-stage lung cancer.

Ultrasound-guided erector spinae plane block for postoperative short-term outcomes in lumbar spine surgery: A meta-analysis and systematic review

BACKGROUND

Patients undergoing lumbar spine surgery usually suffer from moderate to severe acute pain. Erector spinae plane block (ESPB) has been applied to relieve acute pain in various surgeries and improve postoperative outcomes. This study aimed to further identify the efficacy and safety of erector spinae plane block in patients undergoing lumbar spine surgery. This study also evaluates the outcomes of the erector spinae plane block compared with other regional blocks.

METHODS

We searched PubMed, Web of Science, Cochrane library, Embase, and CINAHL databases to identify all randomized controlled trials evaluating the effects of ESPB on postoperative pain after lumbar spine surgery. The primary outcome is postoperative total opioid consumption in 24 hours. The secondary outcomes are postoperative pain scores, intraoperative opioid consumption, time to first rescue analgesia, number of patients requiring rescue analgesia, first time to ambulation after surgery, length of hospital stay, patients' satisfaction score, and postoperative side effects such as postoperative nausea and vomiting, itching.

RESULTS

A total of 19 randomized controlled trials are included in the final analysis. Compared with no/sham block, ultrasound-guided erector spinae plane block can decrease perioperative opioid consumption including intraoperative opioid consumption: standardized mean difference (SMD) = -3.04, 95% confidence interval (CI) (-3.99, -2.09), P < .01, and opioid consumption postoperatively: (SMD = -2.80, 95% CI [-3.61, -2.00], P < .01); reduce postoperative pain at 2, 6, 12, 24, and 48 hours both at rest and movement; meanwhile shorten time to hospital length of stay: (SMD = -1.01, 95% CI [-1.72, 0.30], P = .006), decrease postoperative nausea and vomiting (RR = 0.35, 95% CI [0.27, 0.46], P < .00001), and improve patient satisfaction (SMD = -2.03, 95% CI [-0.96, 3.11], P = .0002). But ultrasound-guided ESPB doesn't shorten the time to ambulation after surgery (SMD = -0.56, 95% CI [-1.21, 0.08], P = .09). Additionally, ESPB is not superior to other regional blocks (e.g., thoracolumbar interfascial plane/midtransverse process to pleura block).

CONCLUSION

This meta-analysis demonstrates that ultrasound-guided ESPB can provide effective postoperative analgesia in patients undergoing lumbar spine surgery and improve postoperative outcomes, and it deserves to be recommended as an analgesic adjunct in patients undergoing lumbar spine surgeries.

Laparoscopic Repeat Liver Resection-Selecting the Best Approach for Repeat Liver Resection

Recurrence of liver cancers after liver resection (LR), such as recurrences of hepatocellular carcinoma and colorectal liver metastases, is often treated with repeat LR (RLR) as the only curative treatment. However, RLR is associated with an increased risk of complications. The indications for the currently emerging laparoscopic LR and its advantages and disadvantages for repeat treatment are still under discussion. Our multi-institutional propensity-score matched analyses of laparoscopic vs. open RLRs for hepatocellular carcinoma showed the feasibility of laparoscopic RLR with comparable short- and long-term outcomes. Small blood loss and low morbidity was observed in selected patients treated using laparoscopic RLR in which total adhesiolysis can be dodged, with speculations that laparoscopic minor repeated LR can minimize functional deterioration of the liver. However, there are several disadvantages, such as easily occurring disorientation and difficulty in repeated wide-range dissection of Glissonian pedicles. Recently emerging small anatomical resection, indocyanine green fluorescence-guided surgery, and robot-assisted surgery are promising tools for the further development of laparoscopic RLR. This review discusses how laparoscopic RLR, as a powerful unique local therapy causing less damage to the residual liver and surrounding structures, could contribute to the outcomes of repeated treatments for cancers and its future perspectives.

The prognostic value of admission D-dimer level in patients with cardiogenic shock after acute myocardial infarction

Background

Shock is associated with the activation of the coagulation and fibrinolytic system, and D-dimer is the degradation product of cross-linked fibrin. However, the prognostic value of D-dimer in patients with cardiogenic shock (CS) after acute myocardial infarction (AMI) remains unclear.

Methods

We retrospectively analyzed the data of consecutive patients with CS complicating AMI. The primary endpoint was 30-day mortality and the secondary endpoint was the major adverse cardiovascular events (MACEs) including 30-day all-cause mortality, ventricular tachycardia/ventricular fibrillation, atrioventricular block, gastrointestinal hemorrhage, and non-fatal stroke. Restricted cubic spline (RCS) analyses were performed to assess the association between admission D-dimer and outcomes. A multivariable Cox regression model was performed to identify independent risk factors. The risk predictive potency with D-dimer added to the traditional risk scores was evaluated by C-statistics and the net reclassification index.

Results

Among 218 patients with CS complicating AMI, those who died during the 30-day follow-up presented with worse baseline characteristics and laboratory test results, including a higher level of D-dimer. According to the X-tile program result, the continuous plasma D-dimer level was divided into three gradients. The 30-day all-cause mortality in patients with low, medium, and high levels of D-dimer were 22.4, 53.3, and 86.2%, respectively (p < 0.001 for all). The 30-day incidence of MACEs was 46.3, 77.0, and 89.7%, respectively (p < 0.001). In the multivariable Cox regression model, the trilogy of D-dimer level was an independent risk predictor for 30-day mortality (median D-dimer cohort: HR 1.768, 95% CI 0.982-3.183, p = 0.057; high D-dimer cohort: HR 2.602, 95% CI 1.310-5.168, p = 0.006), a similar result was observed in secondary endpoint events (median D-dimer cohort: HR 2.012, 95% CI 1.329-3.044, p = 0.001; high D-dimer cohort: HR 2.543, 95% CI 1.452-4.453, p = 0.001). The RCS analyses suggested non-linear associations of D-dimer with 30-day mortality. The enrollment of D-dimer improved risk discrimination for all-cause death when combined with the traditional CardShock score (C-index: 0.741 vs. 0.756, p _difference = 0.004) and the IABP-SHOCK II score (C-index: 0.732 vs. 0.754, p _difference = 0.006), and the GRACE score (C-index: 0.679 vs. 0.715, p _difference < 0.001). Similar results were acquired after logarithmic transformed D-dimer was included in the risk score. The improvements in reclassification which were calculated as additional net reclassification index were 7.5, 8.6, and 12.8%, respectively.

Conclusion

Admission D-dimer level was independently associated with the short-term outcome in patients with CS complicating AMI and addition of D-dimer brought incremental risk prediction value to traditional risk prediction scores.

Adequacy of sedation analgesia to support the comfort of neonates undergoing therapeutic hypothermia and its impact on short-term neonatal outcomes

Objectives

We aimed to evaluate (1) whether sedation analgesia (SA) used during therapeutic hypothermia (TH) was efficient to support the wellbeing of neonates with hypoxic-ischemic encephalopathy, (2) the SA level and its adjustment to clinical pain scores, and (3) the impact of inadequate SA on short-term neonatal outcomes evaluated at discharge.

Methods

This was an observational retrospective study performed between 2011 and 2018 in two level III centers in Alsace, France. We analyzed the wellbeing of infants by using the COMFORT-Behavior (COMFORT-B) clinical score and SA level during TH, according to which we classified infants into four groups: those with excess SA, adequate SA, lack of SA, and variability of SA. We analyzed the variations in doses of SA and their justification. We also determined the impact of inadequate SA on neonatal outcomes at discharge by multivariate analyses with multinomial regression, with adequate SA as the reference.

Results

A total of 110 patients were included, 89 from Strasbourg university hospital and 21 from Mulhouse hospital. The COMFORT-B score was assessed 95.5% of the time. Lack of SA was mainly found on the first day of TH (15/110, 14%). In all, 62 of 110 (57%) infants were in excess of SA over the entire duration of TH. Most dose variations were related to clinical pain scores. Inadequate SA was associated with negative short-term consequences. Infants with excess of SA had a longer duration of mechanical ventilation [mean ratio 1.46, 95% confidence interval (CI), 1.13-1.89, p = 0.005] and higher incidence of abnormal neurological examination at discharge (odds ratio 2.61, 95% CI, 1.10-6.18, p = 0.029) than infants with adequate SA.

Discussion

Adequate SA was not easy to achieve during TH. Close and regular monitoring of SA level may help achieve adequate SA. Excess of SA can be harmful for newborns with hypoxic-ischemic encephalopathy who are undergoing TH.

Left ventricular myocardial work index and short-term prognosis in patients with light-chain cardiac amyloidosis: a retrospective cohort study

Background

Reports show that the left ventricular myocardial work index (LVMWI) is a novel parameter for evaluating cardiac function. Decompensated heart failure leads to a high rate of early mortality in advanced patients with light-chain cardiac amyloidosis (AL-CA) and prevents them from a relatively delayed response to chemotherapy. This study aimed to assess the association of the LVMWI with short-term outcomes and to construct a simple model for risk stratification.

Methods

A total of 79 patients with an initial diagnosis of AL-CA were included in this retrospective cohort study. LVMWI was calculated by integrating brachial artery cuff blood pressure and left ventricular longitudinal strain (LVLS). The short-term outcome was defined as 6-month all-cause mortality. Receiver operating characteristic (ROC), logistic regression, and Kaplan-Meier analysis were used in this study.

Results

The median follow-up time was 21 months (3-36 months), and 23 (29%) patients died in the first 6 months. The time-dependent ROC and the area under the curve (AUC) showed that the LVMWI had the best predictive potential at the 6-month time point [AUC =0.805; 95% confidence interval (CI): 0.690-0.920]. A bivariate prognostic model based on the LVMWI was constructed, and D-dimer showed a synergistic effect with optimum predicted potential (AUC =0.877; 95% CI: 0.791-0.964). Kaplan-Meier analysis demonstrated that patients with two, one, and none of the variates beyond the cut-off value bore a different risk of 6-month all-cause mortality (accumulated mortality was 86%, 30%, 3%, respectively; log-rank, P<0.001). Multivariate nested logistic regression showed that the level of D-dimer provided an incremental prognostic value (Δχ²=10.3; P=0.001) to the value determined from New York Heart Association (NYHA) classification and the LVMWI.

Conclusions

The LVMWI is associated with the short-term outcome of patients with AL-CA. The D-dimer test provides additional prognostic information for the LVMWI.

Clinical characteristics and short-term outcomes of Japanese encephalitis in pediatric and adult patients: a retrospective study in Northern China

Objective

The study aimed to compare the clinical characteristics and short-term outcomes of pediatric and adult Japanese encephalitis (JE) patients in order to find out the differences.

Methods

From August 2006 to October 2019, 107 patients (62 pediatric patients and 45 adult patients) with JE were enrolled. Clinical characteristics and short-term outcomes were analyzed. The short-term outcome of each patient was defined as a good outcome or poor outcome according to their Glasgow Coma Scale (GCS) scores (GCS > 8 vs. GCS ≤ 8) at discharge.

Results

As for acute complications, the incidence of pulmonary infection was higher in 25 adults (25/45, 55.6%) than in 19 children (19/62, 30.6%; P = 0.01). Upper gastrointestinal bleeding was more common in patients with pulmonary infection, with 10 of these patients experiencing the symptom (10/44, 22.7%) compared to only one patient without pulmonary infection (1/63, 1.6%; P = 0.001). The proportion of mechanical ventilation and admission to the intensive care unit (ICU) for supportive care was higher in patients with pulmonary infection than in patients without infection (P < 0.001, P = 0.008, respectively). The GCS scores at discharge in patients with pulmonary infection (7, 4-12.75) were lower than in patients without pulmonary infection (14, 10-14; P < 0.001). Although the GCS scores at the admission of children (9.5, 7-13) were similar to that of adults (7, 6-13), the GCS scores at the discharge of adults (7, 3.5-13) were lower than that of children (13, 10.75-14; P < 0.001).

Conclusion

The short-term outcome of JE was worse in adults. Pulmonary infection was correlated with a high incidence of upper gastrointestinal bleeding, mechanical ventilation, and ICU hospitalization in JE. Pulmonary infection is a prognostic predictor of short-term outcomes in patients with JE. Vaccination for adults should be initiated.

Laparoscopic natural orifice specimen extraction, a minimally invasive surgical technique for mid-rectal cancers: Retrospective single-center analysis and single-surgeon experience of selected patients

OBJECTIVE

To evaluate the feasibility, safety, and short-term outcomes of middle rectal resection followed by transanal specimen extraction.

METHODS

Forty-four patients with small mid-rectal tumors underwent laparoscopic rectal resection followed by transanal specimen extraction.

RESULTS

The procedure was successful in all patients without intraoperative conversion or additional access. The mean operation time was 182.7 minutes (range, 130-255 minutes), the mean blood loss was 26.5 mL (range, 5-120 mL), the mean postoperative exhaust time was 31.3 hours (range, 16-60 hours), and the mean length of hospital stay was 9.5 days (range, 8-19 days). One patient developed anastomotic leakage, which was treated by intravenous antibiotics and daily pelvic cavity flushes through the abdominal drainage tube. No infection-related complications or anal incontinence were observed. The mean tumor size was 2.1 cm (range, 1.6-3.2 cm), the mean number of harvested lymph nodes was 16.5 (range, 6-31), and the mean follow-up time was 8.5 months (range, 2-16 months). By the last follow-up, no signs of recurrence had been found in any patient.

CONCLUSION

The combination of standard laparoscopic proctectomy and transanal specimen extraction could become a well-established strategy for selected patients.

Comparison of Short-term Outcomes of a Self-expandable Metallic Stent as a Bridge to Laparoscopic Surgery between Right- and Left-sided Obstructive Colorectal Cancers: A Retrospective Observational Study

OBJECTIVES

Few studies have compared the tumor-site-based postoperative short-term outcomes of a bridge to surgery using self-expandable metallic stents. This study compared the perioperative outcomes following stent placement between right- and left-sided obstructive colorectal cancers, focusing on patients undergoing laparoscopic surgery.

METHODS

This study included 127 patients with stage I-IV obstructive colorectal cancer (right-sided, n = 25 [19.7%]; left-sided, n = 102 [80.3%]) who underwent laparoscopic-assisted surgery following stent placement between May 2012 and September 2021. We compared the postoperative complication rates and the success rates of stent placement.

RESULTS

The clinical success rate was not significantly different (92% vs. 97.1%, P = 0.254). The rates of all-grade complications (36% vs. 16.7%, P = 0.05) and postoperative ileus or small-bowel obstruction (20% vs. 2%, P = 0.003) were significantly higher in the right-sided group. The rates of the Clavien-Dindo classification ≥ III complications (8% vs. 6.9%, P = 1) and the median durations of postoperative hospital stay (8 days vs. 8 days, P = 1) were not significantly different. On multivariate analysis, right-sided colon cancer was an independent risk factor for postoperative ileus or small-bowel obstruction (odds ratio [OR]: 16.5, 95% confidence interval [CI]: 2.42-112, P = 0.004) but not for all grades of complications (OR: 2.63, 95% CI: 0.976-7.09, P = 0.056).

CONCLUSIONS

Although the rates of clinical success, postoperative Clavien-Dindo classification ≥ III severe complications, and postoperative hospital stay were comparable, the bridge to surgery following stent placement for right-sided obstructive colon cancer raises concerns about ileus or small-bowel obstruction.

When is the optimal time to discharge patients after liver transplantation with respect to short-term outcomes? A systematic review of the literature and expert panel recommendations

BACKGROUND

Several factors associated with prolonged hospital stay have been described. A recent study demonstrated that hospital length of stay (LOS) is directly associated with an increased cost for liver transplantation (LT) and may be associated with greater mortality; however, the factors associated with post-LT mortality are also related to a prolonged hospital stay, that is, those factors are confounders. Thus, the actual impact of the length of post-LT hospital stay on both short-term and long-term patient and graft survival remains uncertain.

OBJECTIVES

To identify the optimal time to discharge patients after LT with respect to short-term outcomes; readmission rate, 30-90-mortality and morbidity.

METHODS

Systematic review following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel. Initial search keywords for screening were as follows; ((discharge AND (time OR "time point" OR "time-point")) OR "length of hospital stay" OR "length of stay") AND ((liver OR hepatic) AND (transplant OR transplantation)).

PROSPERO ID

CRD42021245598 RESULTS: The strength of recommendation was rated as Weak, and we did not identify the direction of recommendations regarding the optimal timing after LT concerning short-term outcomes, including "Readmission rate," six studies on 30- and/or 90-day mortality, and five studies on "30- and/or 90-day morbidity rate."

CONCLUSIONS

Evidence is scarce to judge the optimal timing to discharge patients after LT with respect to short-term outcomes. In centers with robust outpatient follow-up, discharge can occur safely as early as post-transplant 6-8 days (Quality of Evidence [QOE]; Low | Grade of Recommendation; Weak).

Indocyanine Green Fluorescence Using in Conduit Reconstruction for Patients With Esophageal Cancer to Improve Short-Term Clinical Outcome: A Meta-Analysis

Objectives

This meta-analysis evaluated the short-term safety and efficacy of indocyanine green (ICG) fluorescence in gastric reconstruction to determine a suitable anastomotic position during esophagectomy.

Methods

The Preferred Reporting Items for Systematic Reviews and Meta-Analyzes 2020 (PRISMA) were followed for this analysis.

Results

A total of 9 publications including 1,162 patients were included. The operation time and intraoperative blood loss were comparable in the ICG and control groups. There was also no significant difference in overall postoperative mortality, reoperation, arrhythmia, vocal cord paralysis, pneumonia, and surgical wound infection. The ICG group had a 2.66-day reduction in postoperative stay. The overall anastomotic leak (AL) was 17.6% (n = 131) in the control group and 4.5% (n = 19) in the ICG group with a relative risk (RR) of 0.29 (95% CI 0.18–0.47). A subgroup analysis showed that the application of ICG in cervical anastomosis significantly reduced the incidence of AL (RR of 0.31, 95% CI 0.18–0.52), but for intrathoracic anastomosis, the RR 0.35 was not significant (95% CI 0.09–1.43). Compared to an RR of 0.35 in publications with a sample size of <50, a sample size of >50 had a lower RR of 0.24 (95% CI 0.12–0.48). Regarding intervention time of ICG, the application of ICG both before and after gastric construction had a better RR of 0.25 (95% CI 0.07–0.89).

Conclusions

The application of ICG fluorescence could effectively reduce the incidence of AL and shorten the postoperative hospital stay for patients undergoing cervical anastomosis but was not effective for patients undergoing intrathoracic anastomosis. The application of ICG fluorescence before and after gastric management can better prevent AL.

Short- and Long-Term Outcome of Laparoscopic- versus Robotic-Assisted Right Colectomy: A Systematic Review and Meta-Analysis

Background: There is a rapidly growing literature available on right hemicolectomy comparing the short- and long-term outcomes of robotic right colectomy (RRC) to that of laparoscopic right colectomy (LRC). The aim of this meta-analysis is to revise current comparative literature systematically. Methods: A systematic review of comparative studies published between 2000 to 2021 in PubMed, Scopus and Embase was performed. The primary endpoint was postoperative morbidity, mortality and long-term oncological results. Secondary endpoints consist of blood loss, conversion rates, complications, time to first flatus, hospital stay and incisional hernia rate. Results: 25 of 322 studies were considered for data extraction. A total of 16,099 individual patients who underwent RRC (n = 1842) or LRC (n = 14,257) between 2002 and 2020 were identified. Operative time was significantly shorter in the LRC group (LRC 165.31 min ± 43.08 vs. RRC 207.38 min ± 189.13, MD: −42.01 (95% CI: −51.06−32.96), p < 0.001). Blood loss was significantly lower in the RRC group (LRC 63.57 ± 35.21 vs. RRC 53.62 ± 34.02, MD: 10.03 (95% CI: 1.61−18.45), p = 0.02) as well as conversion rate (LRC 1155/11,629 vs. RRC 94/1534, OR: 1.65 (1.28−2.13), p < 0.001) and hospital stay (LRC 6.15 ± 31.77 vs. RRC 5.31 ± 1.65, MD: 0.84 (95% CI: 0.29−1.38), p = 0.003). Oncological long-term results did not differ between both groups. Conclusion: The advantages of robotic colorectal procedures were clearly demonstrated. RRC can be regarded as safe and feasible. Most of the included studies were retrospective with a limited level of evidence. Further randomized trials would be suitable.

Systemic immune-inflammation index predicted short-term outcomes in ATAD patients undergoing surgery

OBJECTIVE

Systemic immune-inflammation index (SII) is a biomarker that reflect systemic inflammation. We aimed to assess the value of SII in prediction of short-term outcomes in acute type A aortic dissection (ATAD) patients undergoing surgery.

METHOD

All patients underwent surgery for ATAD at our institution from 2018 to 2020 (n = 324) were retrospectively reviewed and divided into low SII (<1582.6 × 10⁹ /L) and high SII (≥1582.6 × 10⁹ /L) group according to optimal cut-off values defined by receiver operating characteristic curve. Cox regression and Kaplan-Meier analyses were performed to illustrate the correlation between SII and postoperative short-outcomes, including 30-day mortality and main complications after surgery.

RESULTS

In total, 48 (14.8%) patients died in 30 days after ATAD surgery. And multivariable Cox analysis demonstrated that high preoperative SII was closely related with 30-day mortality (hazard ratio: 3.532, 95% confidence interval: 1.719-7.255, p = .001). Furthermore, Kaplan-Meier analysis illustrated that the short-term mortality rate increased significantly in high SII group (p < .001). In addition, the incidence of main postoperative complications including major adverse cardiovascular events (p = .001) and multiorgan failure (p = .002) were higher in high SII group. However, the length of intensive unit stay (p = .909) and hospital stay (p = .836) presented no difference in two groups.

CONCLUSION

The study indicated that SII was an available biomarker to predict postoperative short-term prognosis, but not length of stay in intensive care unit and hospital in ATAD patients. And SII may be applied to risk stratification and patient selection in ATAD patients before surgery.

Age, Pulse, Urea, and Albumin Score: A Tool for Predicting the Short-Term and Long-Term Outcomes of Community-Acquired Pneumonia Patients With Diabetes

OBJECTIVE

The predictive performances of CURB-65 and pneumonia severity index (PSI) were poor in patients with diabetes. This study aimed to develop a tool for predicting the short-term and long-term outcomes of CAP in patients with diabetes.

METHODS

A retrospective study was conducted on 531 CAP patients with type 2 diabetes. The short-term outcome was in-hospital mortality. The long-term outcome was 24-month all-cause death. The APUA score was calculated according to the levels of Age (0-2 points), Pulse (0-2 points), Urea (0-2 points), and Albumin (0-4 points). The area under curves (AUCs) were used to evaluate the abilities of the APUA score for predicting short-term outcomes. Cox regression models were used for modeling relationships between the APUA score and 24-month mortality.

RESULTS

The AUC of the APUA score for predicting in-hospital mortality was 0.807 in patients with type 2 diabetes (P<0.001). The AUC of the APUA score was higher than the AUCs of CURB-65 and PSI class (P<0.05). The long-term mortality increased with the risk stratification of the APUA score (low-risk group (0-1 points) 11.5%, intermediate risk group (2-4 points) 16.9%, high risk group (≥5 points) 28.8%, P<0.05). Compared with patients in the low-risk group, patients in the high-risk group had significantly increased risk of long-term death, HR (95%CI) was 2.093 (1.041~4.208, P=0.038).

CONCLUSION

The APUA score is a simple and accurate tool for predicting short-term and long-term outcomes of CAP patients with diabetes.

Does the initial chest radiograph severity in COVID-19 impact the short- and long-term outcome? - a perspective from India

PURPOSE

The chest radiograph (CXR) is among the most widely used investigations in coronavirus disease 2019 (COVID-19) patients. Little is known about its predictive role on the long-term outcome. The purpose of this study was to explore its association with the short and long-term outcome in COVID-19 patients.

METHODS

A total of 1530 patients were assessed for the presence, radiographic pattern and distribution of lung lesions observed on baseline chest radiographs obtained at admission. The Brixia scoring system was applied for semiquantitative assessment of lesion severity. Short-term outcome was determined by clinical severity, duration of hospitalization and mortality. The 1415 survivors in this group were assessed after 5-6 months for the presence of residual symptoms.

RESULTS

About 67% patients had an abnormal baseline CXR. Bilateral involvement with a basal preponderance was observed and ground-glass opacification was the most frequent finding. The Brixia score ranged from 0 to 16, median 2, interquartile range (IQR) [0-6]. About 36% patients were symptomatic on 5-6-month follow-up, with fatigability being the commonest symptom. A good correlation was observed between the CXR score and disease severity as well as duration of hospitalization. On multivariate analysis, the CXR score was found to be a significant independent predictor of in-patient mortality as well as presence of long-term residual symptoms in survivors.

CONCLUSIONS

Disease severity as seen on the chest radiograph appears to play an important role in driving the short and long-term consequences of COVID-19 and could serve as a prognostic indicator, which influences short-term management and long-term follow-up.

Clinical Characteristics, Treatment, and Short-Term Outcome in Patients with Heart Failure and Cancer

(1) Our study aimed to look at the clinical characteristics, treatment and short-term outcomes of patients hospitalized due to heart failure with coexisting cancer. (2) Methods: Seventy one cancer (Ca) patients and a randomly selected 70 patients without Ca, hospitalized due to heart failure exacerbation in the same time period constituted the study group (Ca patient group) and controls (non-Ca group), respectively. Data on clinical characteristics were collected retrospectively for both groups. (3) Results: Cancer patients presented with a less advanced NYHA class, had more frequent HFpEF, a higher peak troponin T level, and smaller left atrium size, as compared with controls. The in-hospital deaths of Ca patients were associated with: a higher New York Heart Association (NYHA) class, lower HgB level, worse renal function, higher K and AST levels, presence of diabetes mellitus, and HFpEF. By multivariate logistic regression analysis, impaired renal function was the only independent predictor of in-hospital death in Ca patients (OR-1.15; CI 1.05; 1.27); p = 0.017). The following covariates entered the regression: NYHA class, HgB, GFR, K⁺, AST, diabetes mellitus t.2, and HFpEF. (4) Conclusions: The clinical picture and the course of heart failure in patients with and without cancer are different.

Case-Fatality and Functional Outcome after Subarachnoid Hemorrhage (SAH) in INternational STRoke oUtComes sTudy (INSTRUCT)

BACKGROUND

There are few large population-based studies of outcomes after subarachnoid hemorrhage (SAH) than other stroke types.

METHODS

We pooled data from 13 population-based stroke incidence studies (10 studies from the INternational STRroke oUtComes sTudy (INSTRUCT) and 3 new studies; N=657). Primary outcomes were case-fatality and functional outcome (modified Rankin scale score 3-5 [poor] vs. 0-2 [good]). Harmonized patient-level factors included age, sex, health behaviours (e.g. current smoking at baseline), comorbidities (e.g.history of hypertension), baseline stroke severity (e.g. NIHSS >7) and year of stroke. We estimated predictors of case-fatality and functional outcome using Poisson regression and generalized estimating equations using log-binomial models respectively at multiple timepoints.

RESULTS

Case-fatality rate was 33% at 1 month, 43% at 1 year, and 47% at 5 years. Poor functional outcome was present in 27% of survivors at 1 month and 15% at 1 year. In multivariable analysis, predictors of death at 1-month were age (per decade increase MRR 1.14 [1.07-1.22]) and SAH severity (MRR 1.87 [1.50-2.33]); at 1 year were age (MRR 1.53 [1.34-1.56]), current smoking (MRR 1.82 [1.20-2.72]) and SAH severity (MRR 3.00 [2.06-4.33]) and; at 5 years were age (MRR 1.63 [1.45-1.84]), current smoking (MRR 2.29 [1.54-3.46]) and severity of SAH (MRR 2.10 [1.44-3.05]). Predictors of poor functional outcome at 1 month were age (per decade increase RR 1.32 [1.11-1.56]) and SAH severity (RR 1.85 [1.06-3.23]), and SAH severity (RR 7.09 [3.17-15.85]) at 1 year.

CONCLUSION

Although age is a non-modifiable risk factor for poor outcomes after SAH, however, severity of SAH and smoking are potential targets to improve the outcomes.

Short-Term Outcomes of Inguinal Hernia Repair in Older Patients: A Retrospective Review at a Tertiary Center

Objectives

Although inguinal hernia (IH) repair is low-risk surgery, older patients are occasionally offered watchful waiting because of their functional status and comorbidities. This study reviewed the surgical outcomes of IH repair in older patients in comparison with outcomes in younger patients.

Methods

This retrospective study included all patients who had IH repair from 2010 to 2020. The primary outcomes of interest were postoperative complications and recurrence.

Results

A total of 262 patients underwent IH repair during the study period; 40% were ≥60 years old. One patient had a recurrence. Among the 8% of patients who had postoperative complications, groin pain was the most common one (1.9%). Female patients had a significantly higher rate of complications than male patients did (38.5% female versus 6.4% male, p<0.001). The rate of complications was also higher for emergency surgery than for elective surgery (22.6% emergency versus 6.1% elective, p<0.001), as well for patients who needed concomitant bowel resection compared with those who did not. Patients who had emergency surgery or postoperative complications had a prolonged hospital stay. 

Conclusions

IH repair in older patients is low-risk surgery, comparable to that in younger patients. In this study, emergency surgery was more common in older than in younger patients and posed a higher risk of complications. We recommend offering elective hernia repair to older patients to avoid the higher complication rate associated with emergency repair.

Preoperative Pre-albumin Concentration as a Predictor of Short-term Outcomes in Elderly Patients With Colorectal Cancer

BACKGROUND/AIM

Population aging results in increasing numbers of elderly persons undergoing surgery for colorectal cancer. We sought to identify objective preoperative indicators of outcomes, with a view toward development of safe, effective treatments for such patients.

PATIENTS AND METHODS

The study included 99 patients aged 80 years or more, who were treated surgically for stage I- III colorectal cancer. Preoperative nutritional status was compared retrospectively between those who suffered postoperative complications (n=40) and those who did not (n=59).

RESULTS

Univariate analysis revealed low prealbumin (PreAlb) concentration (p=0.032) and low platelet-to-lymphocyte ratio (p=0.116) as risk factors for postoperative complications. Multivariate analysis showed preoperative PreAlb concentration to be an independent risk factor (OR=0.884; 95% confidence interval=0.791-0.989; p=0.024) associated with postoperative length of hospital stay (coef.=-0.336, p=0.002).

CONCLUSION

PreAlb, a rapid turnover protein, shows promise as a simple predictor of postoperative complications in elderly patients treated for colorectal surgery.

Impact of preoperative transcatheter rectal arterial chemoembolization with concurrent chemoradiotherapy on surgery and prognosis of patients with locally advanced rectal cancer

BACKGROUND AND OBJECTIVES

To analyze and evaluate the impact of preoperative transcatheter rectal arterial chemoembolization (TRACE) with concurrent chemoradiotherapy on surgery and prognosis of locally advanced rectal cancer (LARC).

METHODS

A total of 118 patients with LARC were enrolled in this nonrandomized prospective study. They were assigned into the experimental group receiving preoperative TRACE with concurrent chemoradiotherapy (TRACE-CRT group, N = 60) and the control group receiving only neoadjuvant chemoradiotherapy (CRT group, N = 58). All patients underwent surgery after their preoperative treatments.

RESULTS

All patients successfully completed the surgical operation. No significant differences were found in sphincter preservation rate and R0 resection rate between TRACE-CRT group and CRT group (p > 0.05). No significant differences were found between the two groups in terms of the perioperative indicators and postoperative complications except mean operation time (165.8 vs. 196.6 min, p < 0.001). Local recurrence occurred in 8 and 5 patients, respectively (p > 0.05). Distant metastasis occurred in 5 and 11 patients, respectively (p < 0.05).

CONCLUSIONS

Adding TRACE in the preoperative standard treatment for LARC did not increase perioperative complications. In addition, it has the potential advantage of preventing distant metastasis. It is worthy of further application and promotion in clinical practice.

Bioimpedance Guided Fluid Management in Peritoneal Dialysis: A Randomized Controlled Trial

BACKGROUND AND OBJECTIVES

Bioelectrical impedance analysis (BIA) devices can help assess volume overload in patients receiving maintenance peritoneal dialysis. However, the effects of BIA on the short-term hard end points of peritoneal dialysis lack consistency. This study aimed to test whether BIA-guided fluid management could improve short-term outcomes in patients on peritoneal dialysis.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

A single-center, open-labeled, randomized, controlled trial was conducted. Patients on prevalent peritoneal dialysis with volume overload were recruited from July 1, 2013 to March 30, 2014 and followed for 1 year in the initial protocol. All participants with volume overload were 1:1 randomized to the BIA-guided arm (BIA and traditional clinical methods) and control arm (only traditional clinical methods). The primary end point was all-cause mortality and secondary end points were cardiovascular disease mortality and technique survival.

RESULTS

A total of 240 patients (mean age, 49 years; men, 51%; diabetic, 21%, 120 per group) were enrolled. After 1-year follow-up, 11(5%) patients died (three in BIA versus eight in control) and 21 patients were permanently transferred to hemodialysis (eight in BIA versus 13 in control). The rate of extracellular water/total body water decline in the BIA group was significantly higher than that in the control group. The 1-year patient survival rates were 96% and 92% in BIA and control groups, respectively. No significant statistical differences were found between patients randomized to the BIA-guided or control arm in terms of patient survival, cardiovascular disease mortality, and technique survival (P>0.05).

CONCLUSIONS

Although BIA-guided fluid management improved the fluid overload status better than the traditional clinical method, no significant effect was found on 1-year patient survival and technique survival in patients on peritoneal dialysis.

Effective Treatment Recommendations for Type 2 Diabetes Management Using Reinforcement Learning: Treatment Recommendation Model Development and Validation

Background

Type 2 diabetes mellitus (T2DM) and its related complications represent a growing economic burden for many countries and health systems. Diabetes complications can be prevented through better disease control, but there is a large gap between the recommended treatment and the treatment that patients actually receive. The treatment of T2DM can be challenging because of different comprehensive therapeutic targets and individual variability of the patients, leading to the need for precise, personalized treatment.

Objective

The aim of this study was to develop treatment recommendation models for T2DM based on deep reinforcement learning. A retrospective analysis was then performed to evaluate the reliability and effectiveness of the models.

Methods

The data used in our study were collected from the Singapore Health Services Diabetes Registry, encompassing 189,520 patients with T2DM, including 6,407,958 outpatient visits from 2013 to 2018. The treatment recommendation model was built based on 80% of the dataset and its effectiveness was evaluated with the remaining 20% of data. Three treatment recommendation models were developed for antiglycemic, antihypertensive, and lipid-lowering treatments by combining a knowledge-driven model and a data-driven model. The knowledge-driven model, based on clinical guidelines and expert experiences, was first applied to select the candidate medications. The data-driven model, based on deep reinforcement learning, was used to rank the candidates according to the expected clinical outcomes. To evaluate the models, short-term outcomes were compared between the model-concordant treatments and the model-nonconcordant treatments with confounder adjustment by stratification, propensity score weighting, and multivariate regression. For long-term outcomes, model-concordant rates were included as independent variables to evaluate if the combined antiglycemic, antihypertensive, and lipid-lowering treatments had a positive impact on reduction of long-term complication occurrence or death at the patient level via multivariate logistic regression.

Results

The test data consisted of 36,993 patients for evaluating the effectiveness of the three treatment recommendation models. In 43.3% of patient visits, the antiglycemic medications recommended by the model were concordant with the actual prescriptions of the physicians. The concordant rates for antihypertensive medications and lipid-lowering medications were 51.3% and 58.9%, respectively. The evaluation results also showed that model-concordant treatments were associated with better glycemic control (odds ratio [OR] 1.73, 95% CI 1.69-1.76), blood pressure control (OR 1.26, 95% CI, 1.23-1.29), and blood lipids control (OR 1.28, 95% CI 1.22-1.35). We also found that patients with more model-concordant treatments were associated with a lower risk of diabetes complications (including 3 macrovascular and 2 microvascular complications) and death, suggesting that the models have the potential of achieving better outcomes in the long term.

Conclusions

Comprehensive management by combining knowledge-driven and data-driven models has good potential to help physicians improve the clinical outcomes of patients with T2DM; achieving good control on blood glucose, blood pressure, and blood lipids; and reducing the risk of diabetes complications in the long term.

Multicenter Propensity Score-Based Study of Laparoscopic Repeat Liver Resection for Hepatocellular Carcinoma: A Subgroup Analysis of Cases with Tumors Far from Major Vessels

Simple Summary

Less morbidity is considered among the advantages of laparoscopic liver resection for HCC patients. However, our previous international, multi-institutional study of laparoscopic repeat liver resection (LRLR) failed to prove it. We hypothesize that these results may be since the study included complex cases performed during the procedure’s developing stage. To examine it, subgroup analysis based on propensity score were performed, defining the proximity of the tumors to major vessels as the complexity. A propensity score matching earned 115 each patient of LRLR and open repeat liver resection (ORLR) without the proximity to major vessels, and the outcomes were compared. With comparable operation time and long-term outcome, less blood loss and less morbidity were shown in LRLR group than ORLR. Even in its worldwide developing stage, LRLR for HCC patients could be beneficial in blood loss and morbidity for the patients with less complexity in surgery.

Abstract

Less morbidity is considered among the advantages of laparoscopic liver resection (LLR) for HCC patients. However, our previous international, multi-institutional, propensity score-based study of emerging laparoscopic repeat liver resection (LRLR) failed to prove this advantage. We hypothesize that these results may be since the study included complex LRLR cases performed during the procedure’s developing stage. To examine it, subgroup analysis based on propensity score were performed, defining the proximity of the tumors to major vessels as the indicator of complex cases. Among 1582 LRLR cases from 42 international high-volume liver surgery centers, 620 cases without the proximity to major vessels (more than 1 cm far from both first–second branches of Glissonian pedicles and major hepatic veins) were selected for this subgroup analysis. A propensity score matching (PSM) analysis was performed based on their patient characteristics, preoperative liver function, tumor characteristics and surgical procedures. One hundred and fifteen of each patient groups of LRLR and open repeat liver resection (ORLR) were earned, and the outcomes were compared. Backgrounds were well-balanced between LRLR and ORLR groups after matching. With comparable operation time and long-term outcome, less blood loss (283.3±823.0 vs. 603.5±664.9 mL, p = 0.001) and less morbidity (8.7 vs. 18.3 %, p = 0.034) were shown in LRLR group than ORLR. Even in its worldwide developing stage, LRLR for HCC patients could be beneficial in blood loss and morbidity for the patients with less complexity in surgery.

Short-term outcome of mothers with severe mental illness admitted to a mother baby unit

BACKGROUND

Mother baby psychiatry units (MBUs) are the expected standard of inpatient care internationally for postpartum mothers with severe mental illness (SMI) and favorable outcomes for mother infant dyads have been reported from these services. However, there are very few such units in low- and middle-income countries. The current study aimed to assess the short-term outcome of mothers in SMI admitted to an MBU in India.

MATERIALS AND METHODS

Mother infant dyads admitted over a year in the MBU were assessed in detail at admission, discharge, and at 3 months. Tools used included the Brief Psychiatric Rating Scale (BPRS), Young's Mania Rating Scale, Edinburgh Postnatal Depression Scale, and Clinical Global Impression. Mother infant interaction was assessed using the NIMHANS maternal behavior scale.

RESULTS

The mean age of the 43 mothers admitted in this period was 27.3 ± 6.2 years. For 27 (62.8%) mothers, this was a first episode of psychosis. Affective disorders and acute psychotic disorders were the most common diagnoses. The average duration of stay in the MBU was 25 days. While all mothers showed significant improvement at discharge, mothers with a first episode in the postpartum had higher BPRS scores (Ws = 309.5, P = 0.02) as compared to the others. At 3 months following discharge, all mothers sustained the improvement achieved.

DISCUSSION

Mothers with SMI admitted to an MBU showed significant clinical and dyadic improvement at discharge which was sustained at 3 months. However, the lack of a control group limits the generalizability of the current findings.

CONCLUSION

The study highlighted a favorable short-term outcome among mothers with SMI admitted to a MBU facility.

Appropriate endoscopic treatment selection and surveillance for superficial non-ampullary duodenal epithelial tumors

OBJECTIVES

Superficial nonampullary duodenal epithelial tumors (SNADETs) have become frequently detected and referred for endoscopic resection (ER). However, optimal treatment methods and long-term outcomes after ER of SNADETs have not been fully elucidated. We aimed to clarify them by analyzing our large cohort of patients with SNADETs.

MATERIALS AND METHODS

We enrolled 190 consecutive tumors from 189 patients undergoing ER between January 2004 and September 2019. Cases were stratified into endoscopic submucosal dissection (ESD), conventional endoscopic mucosal resection, (CEMR) and underwater endoscopic mucosal resection (UEMR). Baseline characteristics and short-term outcomes were compared between the groups. Long-term outcomes were also investigated with a median follow-up of 36 months.

RESULTS

ESD significantly exceeded CEMR (96.4% vs. 52.9%; p = .0026) and UEMR (96.4% vs. 50.0%; p = .0008) in complete resection rates for 11- to 20-mm lesions; the differences were not significant for lesions ≤10 mm. Local recurrence only occurred in patients with an incomplete resection. Only patients with submucosal invasion died from the primary neoplasms. The 3- and 5-year disease-free survivals were 91.3% and 83.5%.

CONCLUSIONS

While tumors ≤10 mm seem to be good indications for endoscopic mucosal resection, ESD should be considered for larger tumors to better achieve complete resection. Patients with submucosal invasive carcinomas have a great risk of cancer death. Therefore, a close follow-up and an additional treatment are desirable.

The Predictive Value of Tumor Volume and Its Change on Short-Term Outcome for Esophageal Squamous Cell Carcinoma Treated With Radiotherapy or Chemoradiotherapy

Objectives

To investigate the tumor volume and its change on short-term outcome in esophageal squamous cell carcinoma (ESCC) patients who underwent definitive radiotherapy or chemoradiotherapy.

Methods and Materials

All data were retrospectively collected from 418 ESCC patients who received radiotherapy or chemoradiotherapy at our institution between 2015 and 2019. Short-term outcome using the treatment response evaluation was assessed according to the RECIST 1.1. The tumor volume change rate (TVCR) was defined as follows: TVCR = {1 - [gross tumor volume (GTV) at shrinking irradiation field planning)]/(GTV at the initial treatment planning)} ×100%. Chi square test was used to compare the clinic characteristics in different TVCR groups, and the difference between initial GTV (GTVi) and shrinking GTV (GTVs) was compared using Wilcoxon's sign rank test. Logistic regression analysis and Spearman correlation was performed.

Results

There was a significant decrease in GTVi compared to GTVs (P < 0.001). In univariate analysis, age, cT-stage, TNM stage, treatment modality, GTVi, and TVCR were associated with short-term outcome (all P < 0.05). In multivariate analysis, gender and TVCR were statistically significant (P = 0.010, <0.001) with short-term outcome, and the combined predictive value of gender and TVCR exceeded that of TVCR (AUC, 0.876 vs 0.855).

Conclusions

TVCR could serve to forecast short-term outcome of radiotherapy or chemoradiotherapy in ESCC. It was of great significance to guide the individualized treatment of ESCC.

Erector Spinae Plane Block for Perioperative Pain Control and Short-term Outcomes in Lumbar Laminoplasty: A Randomized Clinical Trial

BACKGROUND

Spine surgery causes severe pain and can be associated with significant opioid utilization; however, the evidence for opioid-sparing analgesic techniques such as erector spinae plane (ESP) block from controlled studies is limited. We aimed to investigate the analgesic effects of ESP block in lumbar laminoplasty.

METHODS

In this prospective, double-blind, controlled single-center trial, 62 consecutive elective lumbar laminoplasty patients were randomized into either a control group (Group G, N=32) or a treatment group (Group E, N=30). Group G received general anesthesia and multimodal analgesia, similar to group E, while Group E received additional bilateral ESP block after induction of general anesthesia. The primary outcome was postoperative pain scores for the first 48 h after surgery, and the secondary outcomes analyzed included intraoperative anesthetic usage, perioperative analgesic consumption, return of bowel function and satisfaction for acute pain management indicated by overall benefit of analgesia score (OBAS).

RESULTS

Significant differences in pain scores over time were found between the two groups (P=0.010), with Group E patients having significantly lower pain scores than Group G during the first six hours (P=0.000). The opioid consumption in Group G was significantly higher than in Group E both intraoperatively (P=0.000) and postoperatively (P=0.0005). Group E patients had lower intraoperative sevoflurane requirement, improved satisfaction with pain management, and earlier return of bowel function than Group G patients.

CONCLUSION

ESP block is effective in reducing postoperative pain scores and lowering opioid utilization (both intraoperatively and postoperatively), resulting in improved patient satisfaction for pain management in lumbar laminoplasty.

Propensity score matching analysis for outcomes of laparoscopic versus open caudate lobectomy

BACKGROUND

To date, laparoscopic caudate lobectomy (LCB) remains a challenge, and evidence about its value is rare. Therefore, this study was performed to assess the benefits of LCB for patients with tumours located in the caudate lobe compared with open caudate lobectomy (OCB).

METHODS

From October 2015 to June 2019, 102 patients meeting the inclusion and exclusion criteria were eligible for this study. The patients were divided into LCB and OCB groups. Short-term outcomes between the groups were compared with propensity score matching (PSM).

RESULTS

LCB was performed in 31 of the 102 included patients. After PSM, 30 patients with well-balanced baseline levels were enrolled in each group. Intraoperative blood loss in the LCB group was less than that in the OCB group (median, 100 versus 200 mL, P = 0.017), even though it did not reach a statistically significant difference after PSM (median, 100 versus 187.5 mL, P = 0.085). Moreover, although post-operative overall complications were similar in the two groups, a tendency of lower rates of respiratory infection in the LCB group than the OCB group was observed (0% versus 12.7%, P = 0.054 before PSM; 0% versus 16.7%, P = 0.063 after PSM). There was no early mortality in either group. LCB had a shorter post-operative hospital stay than OCB (median, 5 versus 6 days, P < 0.001). However, the hospitalization cost was higher in the LCB group than in the OCB group (P < 0.001).

CONCLUSION

LCB is safe and feasible in selected patients when performed by experienced surgeons.

Charlson comorbidity index as a predictor of short-term outcomes after pulmonary resection

Background

The objective of this retrospective study is to evaluate the impact of the CCI on short-term outcomes in pulmonary resection.

Methods

We retrospectively analyzed 1,309 patients who underwent pulmonary surgery consecutively in our hospital.

Results

All patients were divided into complication group and non-complication group. CCI (P=0.012), blood loss (P=0.015) and type of surgery (P<0.001) were an independent risk factors for complications in multivariate analysis. Assuming a threshold of 3 for defining poor outcomes for pulmonary resection, the sensitivity and specificity were 87.9% and 44.2%, respectively. The area under the curve for CCI was 0.711 (P<0.001). There were 918 (70.1%) patients in the CCI ≤3 group and 391 (29.9%) patients in the CCI ≤3 group. The rate of poor outcome was 3.3% in the CCI ≤3 group, and 9.2% in the CCI >3 group (P<0.001).

Conclusions

The main finding of the present study was that CCI >3 was associated with a poor short-term outcome. For patients with CCI >3, it was suggested that the experienced surgical team should perform pulmonary resection in the shortest time and preserving the lung function as much as possible.

Postoperative Short-term Outcomes Between Sublobar Resection and Lobectomy in Patients with Lung Adenocarcinoma

Background

To investigate postoperative temporary consequences of the enrolled patients with lung adenocarcinoma.

Patients and Methods

We analyzed the clinical data of patients with lung adenocarcinoma admitted by the same surgical team of Peking Union Medical College Hospital (PUMCH) from July 2019 to December 2019. Statistical methods including propensity score matching (PSM) analysis was used to analyze the differences among them.

Results

A total of 108 patients were enrolled, including 50 patients with sublobar resection and 58 patients with lobectomy. Before PSM, there were statistically significant differences in age (p=0.015), hospitalization costs (p=0.042), lymphadenectomy (p=0.000), pathological staging (p=0.000), number of lymph nodes removed (p=0.000), number of positive lymph nodes (p=0.034), chest drainage duration (p=0.000), total chest drainage (p=0.000), length of postoperative hospital stays (p=0.000), postoperative D-dimer level (p=0.030) and perioperative lymphocyte margin (LM) (p=0.003) between sublobar resection and lobectomy. After PSM, there were statistical differences in number of lymph nodes removed (p=0.000), chest drainage duration (p=0.031) and total chest drainage (p=0.002) between sublobar resection and lobectomy. Whether with PSM analysis or not, there were no significant differences in other blood test results, such as inflammation indicators, postoperative neutrophil-lymphocyte ratio (NLR), albumin level, perioperative activity of daily living (ADL) scale scoring margin, complications, postoperative admission to intensive care unit (ICU) and readmission within 30 days. NLR was associated with total chest drainage (p=0.000), length of postoperative hospital stays (p=0.000), postoperative D-dimer level (p=0.050) and ADL scale scoring margin (p=0.003) between sublobar resection and lobectomy.

Conclusion

Sublobar resection, including wedge resection and segmentectomy, was as safe and feasible as lobectomy in our study, and they shared similar short-term outcomes. Postoperative NLR could be used to detect the clinical outcomes of patients. Secondary resectability of pulmonary function (SRPF) should be the main purpose of sublobar resection.

Treatments and outcomes of encapsulating peritoneal sclerosis in patients undergoing peritoneal dialysis: 295 cases from a nationwide inpatient database in Japan

BACKGROUND

The number of patients undergoing renal replacement therapy is increasing. We evaluated the practice patterns and outcomes of encapsulating peritoneal sclerosis (EPS) in patients undergoing peritoneal dialysis.

METHODS

Using a Japanese national inpatient database, we identified 295 patients with EPS who were hospitalized from July 2010 to March 2017. We categorized them into four groups: those who underwent surgery only (n = 39), those who received corticosteroid treatment only (n = 70), those who underwent both (n = 30), and those who underwent neither (n = 156). We investigated their characteristics, treatments, and outcomes.

RESULTS

More than half of patients were males and never-smokers and had a normal body mass index. Patients tended to undergo parenteral nutrition for 2 months. The proportions of emergency admission, intensive care unit (ICU) admission, central venous catheterization, catecholamine use, mechanical ventilation, and continuous hemodiafiltration were significantly different among the four groups (61%, 8.1%, 37.0%, 44.0%, 8.8%, and 5.8%, respectively). The both-treatment group had a significantly longer hospital stay (37.0 vs. 37.5 vs. 72.5 vs. 31.0 days, p < 0.001) and higher costs (US$16,554 vs. US$17,029 vs. US$33,757 vs. US$13,983, p < 0.001) than the other groups. In total, 52 patients (18%) died during hospitalization. There was no significant difference in inhospital complications and death, discharge status, 30-day readmission, or length of ICU stay among the four groups.

CONCLUSIONS

Our findings provide useful information for clinicians and patients hospitalized for treatment of EPS.

Complications and clinical outcomes of laparoscopic sacrocolpopexy for pelvic organ prolapse

Evidence on laparoscopic sacrocolpopexy (LSC) is lacking. Herein, we describe the complications and outcomes of LSC. This single-centre, retrospective cohort study included women with pelvic organ prolapse (POP) who underwent LSC between 2015 and 2017. Preoperative, intraoperative, postoperative, and demographic data were collected. We evaluated patients using the Pelvic Organ Prolapse Quantification system and questionnaires. The primary outcomes were operative characteristics, perioperative complications, early postoperative complications, and anatomical results at 12 months. Forty-six patients (median age: 71 years) underwent LSC. The median follow-up period was 12.0 ± 5.0 (range: 11-26) months. The perioperative complications were bladder perforation and vaginal injury (2.2%). Two (4.3%) patients required reoperation for port-site hernia. One (2.2%) patient developed a retroperitoneal abscess, and one (2.2%) had worsened stress urinary incontinence after LSC. Three (6.5%) patients presented with recurrence of prolapse. LSC is safe and effective for POP.IMPACT STATEMENTWhat is already known on this subject? Laparoscopic sacrocolpopexy (LSC) has become a widely used intervention strategy during the last decade; nevertheless, few studies have reported its outcomes and complications.What do the results of this study add? We demonstrate that LSC for pelvic organ prolapse (POP) has favourable anatomical and voiding functional results, and few perioperative complications. However, it is important to preoperatively inform patients regarding the incidence of mesh-related postoperative complications, although they are not life-threatening, and secure their informed consent.What are the implications of these findings for clinical practice and/or further research? We believe that the LSC procedure, because of its short-term and functional outcomes in the lower urinary tract discussed here, will be more commonly available in clinical practice as a feasible and safe surgical option for POP. However, prospective, large-sample studies should be performed to verify the efficacy of LSC, as further evaluation of the procedure is required.

Use CT Imaging to Predict the Short-Term Outcome of Concurrent Chemoradiotherapy in Patients With Locally Advanced Esophageal Squamous Cell Carcinoma

Objective:

To extract the computed tomography (CT) imaging features of the primary lesions in patients with advanced esophageal squamous cell carcinoma (ESCC) and to study whether these imaging features can predict the short-term outcome after concurrent chemoradiotherapy (CCRT).

Methods:

From January 2014 to December 2015, a total of 49 patients with locally advanced ESCC who underwent CCRT were analyzed retrospectively. They were randomly categorized into the training and validation groups. Collection of CT imaging of patients before and intermediate stage undergoing radiotherapy. The correlations between imaging characteristics and short-term outcome were analyzed. The accuracy of cutoff value was verified by imaging characteristics of patients in validation group.

Result:

There were 38 patients in the training group and 11 patients in the validation group. 13 patients in the training group were classified as responders and 25 patients as nonresponders. According to the CT imaging before radiotherapy, there are no significant differences between responders and nonresponders. According to the CT imaging in the middle stage of radiotherapy, responders showed significantly higher Roundness than nonresponders (P = .004, 95% confidence interval [CI] = 0.0419-0.212). The areas under the ROC curves for the ability to predict significantly tumor response were 0.768 for Roundness (P = .001, 95% CI = 0.603-0.889). The cutoff value of Roundness is 0.3099. Roundness showed no significant associations with survival parameters.

Conclusions:

Computed tomography imaging in the middle stage of radiotherapy can predict the short-term outcome of concurrent chemoradiotherapy for patients with locally advanced ESCC but have no predictive effect on the total survival time.

Trends in Clinical Characteristics and Short-Term Outcome of HIV-Infected Patients at a Tertiary Care Hospital in South India

Background:

Limited information is available on changing trends in HIV positive patients treated with first-line antiretroviral therapy from India.

Methods:

The clinical characteristics and short-term outcome were compared between a retrospective group enrolled between January 2006 and March 2007 (06-07 group—100 patients) and a prospective group enrolled between February 2011 and March 2012 (10-12 group—85 patients).

Results:

Median age was 36 and 38 years in 06-07 and 10-12 groups, respectively. Median baseline CD4 count was 146 cells/mL³ in the 10-12 group, and it was not significantly different from that of 06-07 group. Tuberculosis was diagnosed 3 times more commonly in the 10-12 group. The retention proportion at the end of 10 months was 68% in the 10-12 group when compared to that of 59% in the 06-07 group.

Conclusion:

There was a trend toward improved outcome over the period of time, but the attrition rate remained high.

Comparative outcomes between palliative ileostomy and colostomy in patients with malignant large bowel obstruction

Objectives: Palliative stoma creation should be considered in patients at high risk of colonic metallic stent failure. However, it is unclear whether ileostomy or colostomy is superior. This study compared short-term outcomes between palliative ileostomy and colostomy. Methods: We identified 82 patients with malignant large bowel obstruction, caused by various advanced cancers, between January 2005 and December 2016. We compared short-term outcomes between the ileostomy group (n = 33) and the colostomy group (n = 49). Results: For all 82 patients, clinical success was achieved. Three patients with ileostomy died within 30 days of ostomy formation. The ileostomy group had statistically significant differences in median operative time (113 vs. 129 minutes, p = 0.045) and blood loss (8 vs. 40 g, p = 0.037) in comparison with the colostomy group. No statistically significant differences were observed in the surgical complications (30.3 vs. 38.8%, p = 0.431), in the median period to oral intake (3 vs. 4 days, p = 0.335) and in the hospital stay after surgery (32 vs. 27 days, p = 0.509) between the two groups. Overall stoma-related complications occurred in 27 (32.9%) patients. Stoma-related complications occurred more frequently in the ileostomy group (16/33 vs. 11/49 patients, p = 0.014). High output stoma (6 patients) and irritation (5 patients) occurred more frequently in the ileostomy group. Conclusions: Palliative colostomy is superior to ileostomy due to fewer stoma-related complications. When ileostomy is required, aggressive interventions for high output stomas should be implemented.

Clinical profile and determinants of short-term outcome of acute kidney injury: A hospital-based prospective study from Northeastern India

CONTEXT

Acute kidney injury (AKI) is an outcome of multiple etiologies and is mostly reversible. Data on its incidence and outcome, particularly from India, are limited.

AIMS

To study the etiology, clinical profile, and short-term prognosis in AKI.

SETTINGS AND DESIGN

A hospital-based prospective observational study on AKI.

SUBJECTS AND METHODS

Seventy-five AKI patients diagnosed by Acute Kidney Injury network criteria were selected. Patients with preexisting chronic kidney disease were excluded.

STATISTICAL ANALYSIS USED

Data were compiled using the Statistical Package for the Social Sciences version 17. Regression analysis was done for determining the association of various variables for mortality. P < 0.05 was considered statistically significant.

RESULTS

The mean age of patients was 41.09 ± 16.17 years with a male:female ratio of 1.42:1. Comorbidities were present in 37.3%, with diabetes mellitus (10.6%) and chronic liver disease (10.6%) being the most common. Fever was the most common (40%) presenting symptom, followed by oliguria (25.8%). Infection was the most common cause of AKI (56%), with sepsis in 26.7% followed by acute gastroenteritis in 17.3%. Pneumonia was the primary focus in 50% of cases with sepsis. Mean serum creatinine and urea at admission were 2.37 ± 0.90 and 92.44 ± 39.67 mg/dl, respectively. Serum creatinine rose progressively to 2.96 ± 1.18 and 3.26 ± 1.56 mg/dl at 24 and 48 h, respectively, since hospitalization. Majority of the cases (73.3%) were nonoliguric. Hemodialysis was necessary in 24% of cases. Mean hospital stay was 8.16 days. In-hospital mortality was 24%. Among survivors, 92.9% had complete renal recovery on discharge. Sepsis, need for hemodialysis, urea >100 mg/dl, and peak serum creatinine >3 mg/dl were contributors to mortality (P < 0.01).

CONCLUSIONS

Infections, especially sepsis, were the most common cause of AKI. Hemodialysis was required in one-quarter of the patients. Sepsis, need for hemodialysis, and high creatinine were associated with a significantly higher mortality.

Neoadjuvant chemotherapy with irinotecan and nedaplatin in a single cycle followed by esophagectomy on cT4 resectable esophageal squamous cell carcinoma: a prospective nonrandomized trial for short-term outcomes

Neoadjuvant chemotherapy (NAC) significantly extends survival in advanced esophageal squamous cell carcinoma (ESCC), but the short-term outcomes for cT4 ESCC remain controversial. Many NAC regimens have been previously reported, although no study has reported a regimen of irinotecan and nedaplatin for cT4 potential resectable ESCC. We evaluated the short-term outcomes of NAC with irinotecan and nedaplatin in a single cycle followed by esophagectomy on cT4 resectable ESCC. A total of 51 patients with cT4 potentially resectable ESCC were eligible for this study. Twenty of these patients underwent NAC, and the other 31 patients underwent surgery alone. The toxicities and response of NAC were evaluated. The clinicopathologic characteristics, responses, toxicities, surgical outcomes, postoperative complications, and survival time between the two groups were analyzed. No significant differences were found in clinicopathologic characteristics between the groups (P > 0.05). The response rate of NAC was 75% (15/20). The differences in the long-axis diameter of the tumor and cT stage between pre- and post-NAC were significant (P < 0.05). Twenty-four toxic events occurred in 11 patients of the NAC group, and 20/24 of these were mild. The R0 resection rates in the NAC group and the surgery alone group were 85% and 64.5%, with no statistically significant difference (P > 0.05). Differences in the pathological T stage and pathological tumor-node-metastasis (TNM) stage were significant (P < 0.05). The overall survival (OS) time and mortality in the NAC group versus the surgery alone group were 31.57 ± 3.06 months versus 15.24 ± 1.46 months and 25% versus 61.3%, respectively. The differences in OS and mortality were significant (P < 0.05). The NAC group and R0 resection were significant and independent predictors of positive prognosis. NAC with irinotecan and nedaplatin in a single cycle followed by esophagectomy on cT4 resectable ESCC as a new NAC is safe and effective.

Short-term outcomes of multicenter prospective cohort study of gastric endoscopic resection: 'Real-world evidence' in Japan

OBJECTIVES

A Japanese multicenter prospective cohort study examining endoscopic resection (ER) for early gastric cancer (EGC) has been conducted using a Web registry developed to determine the short-term and long-term outcomes based on absolute and expanded indications. We hereby present the short-term outcomes of this study.

METHODS

All consecutive patients with EGC or suspected EGC undergoing ER at 41 participating institutions between July 2010 and June 2012 were enrolled and prospectively registered into the Web registry. The baseline characteristics were entered before ER, and the short-term outcomes were collected at 6 months following ER.

RESULTS

Nine thousand six hundred and sixteen patients with 10 821 lesions underwent ER (endoscopic submucosal dissection [ESD]: 99.4%). The median procedure time was 76 min, and R0 resections were achieved for 91.6% of the lesions. Postoperative bleeding and intraoperative perforation occurred in 4.4% and 2.3% of the patients, respectively. Significant independent factors correlated with a longer procedure time (120 min or longer) were as follows: tumor size >20 mm, upper-third location, middle-third location, local recurrent lesion, ulcer findings, gastric tube, male gender, and submucosa. Histopathologically, 10 031 lesions were identified as common-type gastric cancers. The median tumor size was 15 mm. Noncurative resections were diagnosed for 18.3% of the lesions. Additional surgery was performed for 48.6% (824 lesions) of the 1695 noncurative ER lesions with a possible risk of lymph node (LN) metastasis. Among them, 64 (7.8%) exhibited LN metastasis.

CONCLUSIONS

This multicenter prospective study showed favorable short-term outcomes for gastric ESD.

Preoperative Low Weight Affects Long-term Outcomes Following Curative Gastrectomy for Gastric Cancer

BACKGROUND/AIM

A recent nationwide survey using the National Clinical Database in Japan identified a high proportion of low-weight patients, who are defined as low body mass index (BMI) patients, in comparison with Western countries. This study was designed to investigate the influence of low BMI on short- and long-term outcomes after curative gastrectomy for gastric cancer.

PATIENTS AND METHODS

Overall, 1,281 consecutive gastric cancer patients, who underwent curative gastrectomy with radical lymphadenectomy from 1997 through 2012 were retrospectively analyzed. Low BMI and non-low BMI were defined as a BMI<18.5 and BMI>18.5 kg/m², respectively.

RESULTS

Compared to patients with BMI higher than 18.5, those with BMI<18.5 had a significantly shorter duration of surgery (p<0.001) and tended to have lower blood loss (p=0.058). There was no difference in preoperative serum albumin level (p=0.592) and the incidence in postoperative abdominal infection complications (p=0.925) between the two groups. Whereas, BMI<18.5 was significantly associated with female gender, anemia, deeper tumor depth and nodal metastasis. Univariate and multivariate analyses revealed that the BMI<18.5 was an independent poor prognostic factor for overall survival [p=0.010, HR 1.6 (95%CI=1.32-2.30)]. Concerning recurrence, the cumulative incidence rate was significantly higher in patients with BMI<18.5 than those without (p=0.045).

CONCLUSION

Low weight did not have adverse effects on short-term outcomes including postoperative complications. However, there was a negative prognostic impact of low BMI, suggesting the requirement of meticulous treatments and follow-up in these gastric cancer patients.

Surgical outcomes of robot-assisted rectal cancer surgery using the da Vinci Surgical System: a multi-center pilot Phase II study

Introduction

We conducted a multi-center pilot Phase II study to examine the safety of robotic rectal cancer surgery performed using the da Vinci Surgical System during the introduction period of robotic rectal surgery at two institutes based on surgical outcomes.

Methods

This study was conducted with a prospective, multi-center, single-arm, open-label design to assess the safety and feasibility of robotic surgery for rectal cancer (da Vinci Surgical System). The primary endpoint was the rate of adverse events during and after robotic surgery. The secondary endpoint was the completion rate of robotic surgery.

Results

Between April 2014 and July 2016, 50 patients were enrolled in this study. Of these, 10 (20%) had rectosigmoid cancer, 17 (34%) had upper rectal cancer, and 23 (46%) had lower rectal cancer; six underwent high anterior resection, 32 underwent low anterior resection, 11 underwent intersphincteric resection, and one underwent abdominoperineal resection. Pathological stages were Stage 0 in 1 patient, Stage I in 28 patients, Stage II in 7 patients and Stage III in 14 patients. Pathologically complete resection was achieved in all patients. There was no intraoperative organ damage or postoperative mortality. Eight (16%) patients developed complications of all grades, of which 2 (4%) were Grade 3 or higher, including anastomotic leakage (2%) and conversion to open surgery (2%).

Conclusion

The present study demonstrates the feasibility and safety of robotic rectal cancer surgery, as reflected by low morbidity and low conversion rates, during the introduction period.
