Background: Post-acute COVID-19 syndrome (PACS) is a multi-system disease comprising persistent symptomatology after the acute phase of infection. Long-term PACS effects significantly impact patient outcomes, but their incidence remains uncharacterized due to high heterogeneity between studies. Therefore, we aimed to summarize published data on PACS, characterizing the clinical presentation, prevalence, and modifiers of prevalence estimates. Method: In this systematic review and meta-analysis, we research MEDLINE for original studies published from January 1st, 2020, to January 31st, 2021, that reported proportions of PACS manifestations. Studies were eligible for inclusion if they included patients aged ≥18 years with confirmed COVID-19 by RT-PCR or antigen testing and a minimum follow-up of 21 days. The prevalence of individual manifestations across studies was pooled using random-effects meta-analysis. For evaluating determinants of heterogeneity, meta-regression analysis was performed. This study was registered in PROSPERO (CRD42019125025). Results: After screening 1,235 studies, we included 29 reports for analysis. Twenty-seven meta-analyses were performed, and 61 long-term manifestations were described. The pooled prevalence of PACS was 56% (95%CI 45-66%), with the most common manifestations being diminished health status, fatigue, asthenia, dyspnea, myalgias, hyposmia and dysgeusia. Most of the included studies presented high heterogeneity. After conducting the meta-regression analysis, we identified that age, gender, number of comorbidities, and reported symptoms significantly modify the prevalence estimation of PACS long-term manifestations. Conclusion: PACS is inconsistently reported between studies, and population characteristics influence the prevalence estimates due to high heterogeneity. A systematized approach for the study of PACS is needed to characterize its impact adequately.

SUMMARY Published studies have reported variable results on the association between duration of proton pump inhibitor (PPI) use and the risk of dementia. An extensive literature search was performed in PubMed, Embase, Google Scholar, and Cochrane for studies examining the risk of cognitive decline and dementia among PPI users versus non-PPI users in prospective studies. Retrospective database linkage studies, case reports, case series, editorials, uncontrolled cohort studies, cross-sectional studies, and review articles were excluded. Primary outcome was pooled hazard rate (HR) of any dementia among PPI users compared with non-PPI users. Secondary outcomes were pooled HR of Alzheimer’s dementia (AD) and risk with long-term PPI follow-up (more than 5 years) studies. Meta-analysis outcomes, heterogeneity (I2), and meta-regression (for the effect of covariates) were derived by statistical software R and Open meta-analyst. A total of six studies (one RCT and five prospective) with 308249 subjects, average age of 75.8 ± 5.2 years, and follow-up of 5 (range 1.5–11) years were included in the analysis. Pooled HR of any dementia was 1.16 (n = 6, 95% confidence interval (CI) = 0.86–1.47). Results remained unchanged when only studies with long-term PPI use (more than 5 years) were analyzed (n = 4, pooled HR 1.10, 95% CI 0.66–1.53). Finally, the pooled HR for AD was 1.06 (n = 3, 95% CI 0.70–1.41). There was substantial heterogeneity among inclusion studies (I2 = 93%). Meta-regression did not demonstrate a significant role of age at study start (P = 0.1) or duration of PPI use (P = 0.62) to incident dementia. The results of this systematic review and meta-analysis do not show a significant relationship between PPI use and dementia in prospective studies with at least a 5-year follow-up.

Background: The specific benefits of aerobic exercises in smoking cessation are unclear, as they have different characteristics, intensities, and durations. The purpose of this systematic review with meta-analysis was to evaluate the effects of aerobic exercise, with or without co-interventions, compared with a control group of cognitive behavior treatment on smoking cessation. Methods: This review was prospectively registered on PROSPERO, and the searches were performed from 2016 to 2018. Randomized controlled trials evaluating the effects of aerobic exercise, with or without nicotine therapy replacement, compared with usual care were included. The primary outcome was smoking cessation defined as the prevalence of those who quit or continuous abstinence. Meta-analysis was calculated using random effects model in the comprehensive meta-analysis software. Results: The authors identified 18 trials reporting data for a total of 2815 participants. There was moderate-quality evidence that aerobic exercise was better than usual care in promoting smoking cessation at short term (11 trials, risk ratio 0.79; 95% confidence interval, 0.66–0.94). However, there were no differences between aerobic exercises and usual care at medium- or long-term follow-ups. Conclusions: According to review, aerobic exercise may be effective in promoting smoking cessation at short-term, but not at medium- and long-term follow-ups.

ObjectivesTo estimate the change in the standard lipid profile (SLP) of adults diagnosed with ≥3 metabolic syndrome (MetS) factors following aerobic exercise training (AET); and to investigate whether study/intervention covariates are associated with this change.DesignSystematic review with univariate meta-analysis and meta-regression.Data sourcesEnglish language searches of online databases from inception until July 2020.Eligibility criteria(1) Published randomised controlled human trials with study population ≥10 per group; (2) sedentary adults with ≥3 MetS factors but otherwise free of chronic disease, not pregnant/lactating; (3) AET-only intervention with duration ≥12 weeks; and (4) reporting pre–post intervention SLP outcomes.ResultsVarious univariate meta-analyses pooled 48 data sets of 2990 participants. Aerobic exercise training significantly (P<.001) improved all lipids (mmol/L mean difference ranges, 95% CIs): total cholesterol, –0.19 (–0.26 to –0.12) to –0.29 (−0.36 to –0.21); triglycerides, −0.17 (–0.19 to –0.14) to –0.18 (−0.24 to –0.13); high-density lipoprotein-cholesterol (HDL-C), 0.05 (0.03 to 0.07) to 0.10 (0.05 to 0.15); and low-density lipoprotein-cholesterol (LDL-C), –0.12 (–0.16 to –0.9) to –0.20 (−0.25 to –0.14). Meta-regression showed that intensity may explain change in triglycerides and volume may explain change in HDL-C and LDL-C.ConclusionAerobic exercise training positively changes the SLP of sedentary and otherwise healthy adults with ≥3 MetS factors. Adjusting AET intervention training variables may increase the effects of AET on triglycerides and HDL-C.PROSPERO registration numberCRD42020151925.

Background Blood flow restricted exercise (BFRE) improves physical fitness, with theorized positive effects on vascular function. This systematic review and meta-analysis aimed to report (1) the effects of BFRE on vascular function in adults with or without chronic health conditions, and (2) adverse events and adherence reported for BFRE. Methodology Five electronic databases were searched by two researchers independently to identify studies reporting vascular outcomes following BFRE in adults with and without chronic conditions. When sufficient data were provided, meta-analysis and exploratory meta-regression were performed. Results Twenty-six studies were included in the review (total participants n = 472; n = 41 older adults with chronic conditions). Meta-analysis (k = 9 studies) indicated that compared to exercise without blood flow restriction, resistance training with blood flow restriction resulted in significantly greater effects on endothelial function (SMD 0.76; 95% CI [0.36–1.14]). No significant differences were estimated for changes in vascular structure (SMD −0.24; 95% CI [−1.08 to 0.59]). In exploratory meta-regression analyses, several experimental protocol factors (design, exercise modality, exercised limbs, intervention length and number of sets per exercise) were significantly associated with the effect size for endothelial function outcomes. Adverse events in BFRE studies were rarely reported. Conclusion There is limited evidence, predominantly available in healthy young adults, on the effect of BFRE on vascular function. Signals pointing to effect of specific dynamic resistance exercise protocols with blood flow restriction (≥4 weeks with exercises for the upper and lower limbs) on endothelial function warrant further investigation.

Background: Long-term physiotherapy is acknowledged to be crucial to manage motor symptoms for Parkinson’s disease (PD) patients, but its effectiveness is not well understood. Objective: This systematic review and meta-analysis aimed to assess the evidence regarding the effectiveness of long-term physiotherapy to improve motor symptoms and reduce antiparkinsonian medication dose in PD patients. Methods: Pubmed, Cochrane, PEDro, and CINAHL were searched for randomized controlled trials before August 31, 2020 that investigated the effectiveness of physiotherapy for 6 months or longer on motor symptoms and levodopa-equivalent dose (LED) in PD patients with Hoehn and Yahr stage 1– 3. We performed random effects meta-analyses for long-term physiotherapy versus no/control intervention and estimated standard mean differences with 95% confidence intervals (CIs). Levels of evidence were rated by the Grading of Recommendation Assessment, Development and Evaluation approach. Results: From 2,940 studies, 10 studies involving 663 PD patients were assessed. Long-term physiotherapy had favorable effects on motor symptoms in off medication state [– 0.65, 95% CI – 1.04 to – 0.26, p = 0.001] and LED [– 0.49, 95% CI – 0.89 to – 0.09, p = 0.02]. Subgroup analyses demonstrated favorable effects on motor symptoms in off medication state by aerobic exercise [– 0.42, 95% CI – 0.64 to – 0.20, p <  0.001] and LED by multidisciplinary rehabilitation of primarily physiotherapy [– 1.00, 95% CI – 1.44 to – 0.56, p <  0.001]. Quality of evidence for aerobic exercise and multidisciplinary rehabilitation were low and very low. Conclusion: This review provided evidence that long-term physiotherapy has beneficial impact on motor symptoms and antiparkinsonian medication dose in PD patients and could motivate implementation of long-term physiotherapy.

Abstract Introduction It remains unclear whether minimally invasive pancreaticoduodenectomy (MIPD) and open pancreaticoduodenectomy (OPD) influences long-term survival in periampullary cancers. This review aims evaluate long-term survival between MIPD and OPD for periampullary cancers. Methods A systematic review was performed to identify studies comparing long-term survival after MIPD and OPD. The I2 test was used to test for statistical heterogeneity and publication bias using Egger test. Random-effects meta-analysis was performed for all-cause 5-year (main outcome) and 3-year survival, and disease-specific 5-year and 3-year survival. Meta-regression was performed for the 5- year and 3-year survival outcomes with adjustment for study (region, design, case matching), hospital (centre volume), patient (ASA grade, gender, age), and tumor (stage, neoadjuvant therapy, subtype (i.e. ampullary, distal bile duct, duodenal, pancreatic)). Sensitivity analyses performed on studies including pancreatic ductal adenocarcinoma (PDAC) only. Results The review identified 31 relevant studies. Among all 58,622 patients, 8716 (14.9%) underwent MIPD and 49,875 (85.1%) underwent OPD. Pooled analysis revealed similar 5-year overall survival after MIPD compared with OPD (HR: 0.78, 95% CI 0.50–1.22, p = 0.2). Meta-regression indicated case matching, and ASA Grade II and III as confounding covariates. The statistical heterogeneity was limited (I2 = 12, c2 = 0.26) and the funnel plot was symmetrical both according to visual and statistical testing (Egger test = 0.32). Sensitivity subset analyses for PDAC demonstrated similar 5-year overall survival after MIPD compared with OPD (HR 0.69, 95% CI: 0.32–1.50, p = 0.3). Conclusion Long-term survival after MIPD is similar to OPD. Thus, MIPD can be recommended as a standard surgical approach for periampullary cancers.

Abstract Introduction Minimally invasive liver surgery (MILS) for hepatocellular carcinoma (HCC) has gained widespread interest as an alternative to conventional open liver surgery (OLS). However, long-term survival benefits of this approach seem unclear. This meta- analysis was conducted to investigate long-term survival following MILS. Methods A systematic review was performed to identify studies comparing long-term survival after MILS and OLS until January 2020. The I2 test was used to test for statistical heterogeneity and publication bias was assessed using Egger test. Random-effects meta-analysis was performed for all-cause 5-year (main outcome) and 3-year mortality, and disease-specific 5-year and 3-year mortality. Meta-regression was performed for the 5-year and 3-year survival outcomes with adjustment for study factors (region, design), annual center volume, patient factors (ASA grade, gender, age, BMI, cirrhosis, tumor size and number), and resection extent. Sensitivity analyses were performed on studies by study year, region, annual centre volume, resection type. Results The review identified 50 relevant studies including 13,731 patients undergoing liver resection for HCC of which 4,071 (25.8%) underwent MILS. Pooled analysis revealed similar all-cause (OR: 0.83, 95% CI: 0.70 - 1.11, p = 0.3) and disease-specific (OR: 0.93, 95% CI: 0.80 - 1.09, p = 0.4) 5-year mortality after MILS compared with OLS. Sensitivity analysis of published studies from 2010 to 2019 demonstrated a significantly lower disease-specific 3-year mortality (OR 0.75, 95% CI: 0.59 - 0.96, p = 0.022) and all cause 5-year mortality (OR 0.63, 95% CI: 0.50 - 0.81, p = 0.002). Meta- regression identified no confounding factors in all analyses. Conclusions Improvement in MILS techniques over the past decade appears to demonstrate superior disease-specific mortality with MILS compared to OLS. Therefore, MILS can be recommended as a standard surgical approach for HCC.
