The Impact

Object Surgery on the pituitary gland is increasingly being performed through an endoscopic approach. However, there is little published data on its safety and relative advantages over traditional microscope-based approaches. Published reports are limited by small sample size and nonrandomized study design. A meta-analysis allows for a description of the impact of endoscopic surgery on short-term outcomes. Methods The authors performed retrospective review of data from their institution as well as a systematic review of the literature. The pooled data were analyzed for descriptive statistics on short-term outcomes. Results Nine studies (821 patients) met inclusion criteria. Overall, the pooled rate of gross tumor removal was 78% (95% CI 67–89%). Hormone resolution was achieved in 81% (95% CI 71–91%) of adrenocorticotropic hormone secreting tumors, 84% (95% CI 76–92%) of growth hormone secreting tumors, and 82% (95% CI 70–94%) of prolactin secreting tumors. The pooled complication rates were 2% (95% CI 0–4%) for CSF leak and 1% (95% CI 0–2%) for permanent diabetes insipidus. There were 2 deaths reported in the literature that were both related to vascular injury, giving an overall mortality rate of 0.24%. Conclusions The results of this meta-analysis support the safety and short-term efficacy of endoscopic pituitary surgery. Future studies with long-term follow-up are required to determine tumor control.

SUMMARY Changes in the structure of surgical training have affected trainees’ operative experience. Performing an esophagectomy is being increasingly viewed as a complex technical skill attained after completion of the routine training pathway. This systematic review aimed to identify all studies analyzing the impact of trainee involvement in esophagectomy on clinical outcomes. A search of the major reference databases (Cochrane Library, MEDLINE, EMBASE) was performed with no time limits up to the date of the search (November 2017). Results were screened in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and study quality assessed using the MINORS (Methodological Index for Non-Randomized Studies) criteria. Four studies that included a total of 42 trainees and 16 consultants were identified, which assessed trainee involvement in open esophagogastric resectional surgery. A total of 1109 patients underwent upper gastrointestinal procedures, of whom 904 patients underwent an esophagectomy. Preoperative characteristics, histology, neoadjuvant treatment, and overall length of hospital stay were comparable between groups. One study found higher rates of anastomotic leaks in procedures primarily performed by trainees as compared to consultants (P < 0.01)—this did not affect overall morbidity or survival; however, overall anastomotic leak rates from the published data were 10.4% (trainee) versus 6.3% (trainer) (P = 0.10). A meta-analysis could not be performed due to the heterogeneity of data. The median MINORS score for the included studies was 13 (range 11–15). This study demonstrates that training can be achieved with excellent results in high-volume centers. This has important implications on the consent process and training delivered, as patients wish to be aware of the risks involved with surgery and can be reassured that appropriately supervised trainee involvement will not adversely affect outcomes.

Objective The aim of this study was to conduct a systematic review and meta-analysis to investigate the impact of premorbid beta-blockers on mortality in patients with sepsis. Data Sources We searched EMBASE, the Cochrane Central Register of Controlled Trials, and MEDLINE for eligible studies. The protocol was registered at the PROSPERO (CRD42021256813). Study Selection Two authors independently evaluated the following inclusion criteria: (1) randomized controlled trials, cohort studies, cross-sectional studies; (2) patients with sepsis aged ≥18 years, and (3) premorbid beta-blocker use. Data Extraction Two authors extracted the patients’ characteristics and outcomes independently. All analyses were performed using the random-effects models. The primary outcome was short-term mortality, defined as mortality within 30 days, in-hospital or intensive care unit mortality. Data Synthesis Ten studies (n = 24 748 patients) were included. The pooled odds ratio (OR) of short-term mortality associated with the premorbid use of beta-blockers was 0.85 (95% confidence interval [CI], 0.69-1.04; P = .12; I2 = 50%). Five studies reported an adjusted OR of short-term mortality. The pooled adjusted OR of short-term mortality associated with the premorbid use of beta-blockers was 0.73 (95% CI, 0.65-0.83; P < .001; I2 = 0%). Conclusion Premorbid beta-blockers were associated with a lower short-term mortality in patients with sepsis.

PurposeThe benefit of adjuvant therapy (AT) for biliary tract cancer (BTC) is unclear, with conflicting results from nonrandomized studies. We report a systematic review and meta-analysis to determine the impact of AT on survival.MethodsStudies published between 1960 and November 2010, which evaluated adjuvant chemotherapy (CT), radiotherapy (RT), or both (CRT) compared with curative-intent surgery alone for resected BTC were included. Only tumors of the gallbladder and bile ducts were assessed. Published data were extracted and computed into odds ratios (ORs) for death at 5 years. Subgroup analyses of benefit based on lymph node (LN) or resection margin positivity (R1) were prespecified. Data were weighted by generic inverse variance and pooled using random-effect modeling.ResultsTwenty studies involving 6,712 patients were analyzed. There was a nonsignificant improvement in overall survival with any AT compared with surgery alone (pooled OR, 0.74; P = .06). There was no difference between gallbladder and bile duct tumors (P = .68). The association was significant when the two registry analyses were excluded. Those receiving CT or CRT derived statistically greater benefit than RT alone (OR, 0.39, 0.61, and 0.98, respectively; P = .02). The greatest benefit for AT was in those with LN-positive disease (OR, 0.49; P = .004) and R1 disease (OR, 0.36; P = .002).ConclusionThis analysis supports AT for BTC. Prospective randomized trials are needed to provide better rationale for this commonly used strategy. On the basis of our data, such trials could involve two active comparators rather than a no-treatment arm among patients with LN-positive or R1 disease.

The Impact

Prolonged lockdown/restriction measures due to the COVID-19 pandemic have reportedly impacted opportunities to be physically active for a large proportion of the population in affected countries globally. The exact changes to physical activity and sedentary behaviours due to these measures have not been fully studied. Accordingly, the objective of this PROSPERO-registered systematic review is to evaluate the available evidence on physical activity and sedentary behaviours in the general population during COVID-19-related lockdown/restriction measures, compared to prior to restrictions being in place. Defined searches to identify eligible studies published in English, from November 2019 up to the date of submission, will be conducted using the following databases: CENTRAL, MEDLINE, EMBASE, CINAHL, SPORTDiscus, PSYCinfo, Coronavirus Research Database, Public Health Database, Publicly Available Content Database, SCOPUS, and Google Scholar. The applied inclusion criteria were selected to identify observational studies with no restrictions placed on participants, with outcomes regarding physical activity and/or sedentary behaviour during lockdown/restriction measures, and with comparisons for these outcomes to a time when no such measures were in place. Where appropriate, results from included studies will be pooled and effect estimates will be presented in random effects meta-analyses. To the best of our knowledge, this will be the first systematic review to evaluate one complete year of published data on the impact of COVID-19-related lockdown/restriction measures on physical activity and sedentary behaviour. Thus, this systematic review and meta-analysis will constitute the most up-to-date synthesis of published evidence on any such documented changes, and so will comprehensively inform clinical practitioners, public health agencies, researchers, policymakers and the general public regarding the effects of lockdown/restriction measures on both physical activity and sedentary behaviour.

Abstract Background Previous studies have found various incidences of right ventricular (RV) injury and its association with clinical outcome in patients with acute respiratory distress syndrome (ARDS). In this systematic review and meta-analysis, we aimed to investigate the impact of the presence of RV injury on mortality in patients with ARDS. Method We searched Medline, Embase, and the Cochrane Central Register of Controlled Trials for studies investigating the association between RV injury and mortality. Two authors independently evaluated whether studies meet eligibility criteria and extracted the selected patients’ and studies’ characteristics and outcomes. RV injury was diagnosed by trans-thoracic echocardiogram (TTE), trans-esophageal echocardiogram (TEE) and PAC (pulmonary artery catheter) in the included studies. The primary outcome was the association between mortality and the presence of RV injury in patients with ARDS. The overall reported mortality was defined as either the intensive care unit (ICU) mortality, in-hospital mortality, or mortality within 90 days, and short-term mortality was defined as ICU-mortality, in-hospital mortality, or mortality within 30 days. Results We included 9 studies (N = 1861 patients) in this meta-analysis. RV injury that included RV dysfunction, RV dysfunction with hemodynamic compromise, RV failure, or acute cor-pulmonale was present in 21.0% (391/1,861). In the pooled meta-analysis, the presence of RV injury in patients with ARDS was associated with significantly higher overall mortality (OR 1.45, 95% CI 1.13–1.86, p-value = 0.003, I2 = 0%), as well as short-term mortality (OR 1.48, 95% CI 1.14–1.93, p-value = 0.003, I2 = 0%). Conclusion In this systematic review and meta-analysis including 1861 patients with ARDS, the presence of RV injury was significantly associated with increased overall and short-term mortality. Trial registration: The protocol was registered at PROSPERO (CRD42020206521).
