RESUMO
BACKGROUND: Limited data comparing recovery of health-related quality of life (HRQoL) after laparoscopic (LDP) versus open distal pancreatectomy (ODP) are available. The aim of this study was to assess the impact of laparoscopy on postoperative HRQOL after DP using the Patient-Reported Outcomes Measurement Information System (PROMIS). METHODS: Data from consecutive patients who underwent DP (2020-2022) enrolled in a prospective clinical trial were reviewed. Patients completed PROMIS-29 plus 2 profile preoperatively, at postoperative day (POD) 15, 30, 90, and 180. Linear regression analysis adjusting for confounders including preoperative PROMIS scores, age, gender, ASA score, diagnosis, and multivisceral resection was used to estimate mean between-group differences (MD) in postoperative PROMIS domains T scores. RESULTS: Overall, 202 patients (118 laparoscopic, 86 open) underwent DP (median age 66 years, pancreatic cancer 41%, multivisceral resection 10%, median LOS 6 days). At POD15, LDP was associated with higher physical function (MD 5.6) and participation in social roles and activities scores (MD 3.8), reduced fatigue (MD - 2.7) and sleep disturbance (MD - 3.8) compared to ODP. At POD30, LDP patients had higher physical function (MD 5.2) and participation in social roles and activities scores (MD 6.0), reduced fatigue (MD - 3.5), and anxiety (MD - 4.0) compared to ODP. No between-group differences were found in HRQoL domains at POD90 and 180. Six months after surgery, the proportions of patients who had not recovered to preoperative physical function, participation in social roles and activities, fatigue, pain interference, sleep disturbance, cognitive function, depression, and anxiety were 31%, 31%, 28%, 20%, 15%, 14%, 8%, and 7%, respectively. CONCLUSIONS: According to PROMIS, LDP resulted in improved physical and social functioning and reduced anxiety and fatigue up to 30 days after surgery compared to ODP. At 6 months after surgery, recovery of physical domains is still incomplete in up to 30% of patients.

OBJECTIVE: To contribute evidence for the reliability, construct validity, and responsiveness of the Patient-Reported Outcomes Measurement Information System 29 (PROMIS-29) profile questionnaire as a measure of recovery after pancreatic surgery. BACKGROUND: PROMIS questionnaires have been recommended to evaluate postdischarge recovery after surgery. Evidence supporting their measurement properties in pancreatic surgery is missing. METHODS: An observational validation study designed according to the COSMIN checklist was conducted including data from a prospective clinical trial. Patients undergoing pancreatectomy completed PROMIS-29 preoperatively and on postoperative days (PODs) 15, 30, 90, and 180. Reliability was assessed by internal consistency using Cronbach α. Construct validity was assessed by known-groups comparison. Responsiveness was evaluated hypothesizing that scores would be higher (1) preoperatively versus POD15, (2) on POD30 versus POD15, (3) on POD90 versus POD30, and (4) on POD180 versus POD90. RESULTS: Overall, 510 patients were included in the study. Reliability was good to excellent (α values ranged from 0.82 to 0.97). Data supported 4 of 5 hypotheses tested for construct validity for 5 domains (physical function, anxiety, depression, fatigue, and ability to participate in social roles) at most time points. Responsiveness hypotheses 1, 2, and 3 were supported by the data for physical function, fatigue, sleep disturbance, pain interference, and ability to participate in social roles domains. CONCLUSIONS: PROMIS had excellent reliability, discriminated between most groups expected to have different recovery trajectories and was responsive to the expected trajectory of recovery up to 90 days after surgery. Our findings support the use of PROMIS-29 profile as a patient-reported outcome measure of postdischarge recovery after pancreatectomy.

BACKGROUND: The rate of patients with pancreatic ductal adenocarcinoma (PDAC) receiving neoadjuvant chemotherapy is increasing, but upfront resection is still offered to most patients with resectable or borderline resectable disease. Encouraging data reported in adjuvant chemotherapy trials prompts surgeons towards upfront surgery, but such trials are subject to a significant selection bias. This systematic review aims to summarize available high-quality evidence regarding survival of patients treated with upfront surgery for PDAC. METHODS: Pubmed, Cochrane, and Web of Science Databases were interrogated for prospective studies published between 2000 and 2021 that included at least a cohort of patients treated with upfront surgery for resectable or borderline resectable PDAC. The Cochrane Collaboration's risk-of-bias tool for randomized trials (RoB-2) was used to assess risk of bias in all randomized studies. Patient weighted median overall survival (OS) and disease-free survival (DFS) were calculated. RESULTS: Overall, 8,341 abstracts were screened, 17 reports were reviewed in full text, and finally 5 articles and 1 conference abstract underwent data extraction. Included studies were published between 2014 and 2021. All studies were RCTs comparing different neoadjuvant treatment strategies to upfront surgery. Three studies included only resectable PDAC patients, two studies recruited patients with resectable and borderline resectable disease, and one study selected only borderline resectable patients. A total of 439 patients were included in the upfront resection cohorts of the 6 studies, ranging between 20 to 180 patients per study. The weighted median OS after upfront surgery was 18.8 (95% CI 12.4 - 20.6) months. Median DFS was 9 (95% CI 1.6 - 12.5) months. Resection rate was 74.5% (range 65-90%). Adjuvant treatment was initiated in 68% (range 43-77%) of resected patients. CONCLUSIONS: High-quality data for PDAC patients undergoing upfront surgery is scarce. Meta-analysis from the included studies showed a significantly shorter OS and DFS compared to recently published studies focusing on adjuvant combination chemotherapy, suggesting that the latter may overestimate survival due to the exclusion of most patients scheduled for upfront surgery.
RESUMO
INTRODUCTION: Rare genetic functional variants can contribute to 30-40% of functional variability in genes relevant to drug action. Therefore, we investigated the role of rare functional variants in antidepressant response. METHOD: Mexican-American individuals meeting the Diagnostic and Statistical Manual-IV criteria for major depressive disorder (MDD) participated in a prospective randomized, double-blind study with desipramine or fluoxetine. The rare variant analysis was performed using whole-exome genotyping data. Network and pathway analyses were carried out with the list of significant genes. RESULTS: The Kernel-Based Adaptive Cluster method identified functional rare variants in 35 genes significantly associated with treatment remission (False discovery rate, FDR <0.01). Pathway analysis of these genes supports the involvement of the following gene ontology processes: olfactory/sensory transduction, regulation of response to cytokine stimulus, and meiotic cell cycleprocess. LIMITATIONS: Our study did not have a placebo arm. We were not able to use antidepressant blood level as a covariate. Our study is based on a small sample size of only 65 Mexican-American individuals. Further studies using larger cohorts are warranted. CONCLUSION: Our data identified several rare functional variants in antidepressant drug response in MDD patients. These have the potential to serve as genetic markers for predicting drug response.
