Background Cystic fibrosis (CF) is a multiorgan disease affecting the lungs pancreas and gastrointestinal tract. Pulmonary complications are the most common clinical manifestation of the disease. Recent advances in the treatment of pulmonary complications have resulted in substantial improvement in life expectancy. Less than 10% of persons with CF (PWCF) develop liver disease (CFLD). There is conflicting evidence as to the impact of liver disease on mortality in CF, with evidence suggesting that CFLD contributes to increased mortality in CF, while other studies suggest that the impact on mortality is limited. Understanding the contribution of liver disease to mortality in CF is essential if further improvements in life expectancy are to be achieved. Objective: To document the impact of liver disease on life expectancy for PWCF. Methods: This systematic review will be conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P 2015). PubMed, Medline and Embase will be searched for English language publications between 1949 and 2020 reporting liver related and all-cause mortality in CF. Observational studies that use an unambiguous definition of liver disease in well-defined CF populations will be included. Studies with and without a comparator will be evaluated. Clinical trials of ursodeoxycholic acid will be excluded as well as organ transplantation outcome studies. The ROBINS-1 risk of bias tool for non-randomised studies will be used to evaluate the quality of the studies. We will provide a narrative synthesis of our findings using tabular formats to highlight any impact of liver disease on mortality in CF. Conclusion: It is anticipated that this review will bring clarity to the question of whether CFLD shortens life expectancy in PWCF and stimulate new approaches to the management of CFLD. Registration: This protocol has been submitted for registration on PROSPERO and is awaiting review.

150 Background: Nearly 50% of men diagnosed with prostate cancer may receive treatment with some form of androgen deprivation therapy (ADT). While some side effects of ADT are well acknowledged, the specific impact of ADT on cognitive function is uncertain. Our objective was to perform a systematic review and meta-analysis assessing the impact of ADT on overall cognitive decline, and the risks of Alzheimers, Parkinson’s disease. Methods: Relevant studies were identified through search of English language articles indexed in PubMed Medline, PsycINFO, Cochrane Library and Web of Knowledge/Science. First, we assessed rates of cognitive decline in five cohorts from three studies. Second, we assessed rates of Alzheimer’s or Parkinson disease using three large retrospective studies. A pooled-analysis was conducted using a meta-analysis. Weighted averages were reported as odds ratios (OR) with 95% confidence intervals (CI) using RevMan and a DerSimonian and Laird random-effects model. The heterogeneity test was measured using the Q-Mantel-Haenszel ( P< 0.10 was considered of significant heterogeneity). Results: With respect to overall cognitive decline (defined as scoring 1.5 standard deviations [SD] in two or more objective cognitive tests), patients receiving ADT had higher odds of overall cognitive decline than patients with prostate cancer not treated with ADT or health controls (OR: 2.03, 95% CI: 1.42–2.90). Furthermore, men with a history of ADT for prostate cancer had higher odds of developing Alzheimer’s and Parkinson dementia compared to men with prostate cancer not treated with ADT (OR: 1.32, 95% CI: 1.27–1.37). Conclusions: Men receiving ADT for prostate cancer performed significantly worse on measures of overall cognitive function. Additionally, results from the three large observational trials included suggest men exposed to ADT for prostate cancer have higher rates of Parkinson/Alzheimer’s compared to men without ADT.

IntroductionThe effects of interventions targeting weight loss on physical health are well described, yet the evidence for mental health is less clear. It is essential to better understand the impact of weight management interventions on mental health to optimise care and minimise risk of harm. We will assess the effect of behavioural weight management interventions on mental health in adults with overweight and obesity.Methods and analysisThe systematic review will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance. We will include behavioural weight management interventions with a diet and/or physical activity component focusing on weight loss for adults with a body mass index ≥25 kg/m2. Randomised controlled trials (RCTs) and cluster RCTs will be the only eligible study designs. Outcomes of interest will be related to mental health. The following databases were searched from inception to 07 May 2019: MEDLINE, Embase, Cochrane database (CENTRAL), PsycINFO, ASSIA, AMED and CINAHL. The search strategy was based on four concepts: (1) adults, defined as ≥18 years, with overweight/obesity, defined as BMI ≥25kg/m², (2) weight management interventions, (3) mental health outcomes and (4) study design. The search was restricted to English-language published papers, with no other restrictions applied. Two stage screening for eligibility will be completed by two independent reviewers, with two independent reviewers completing data extraction and risk of bias assessment. Data permitting, a random-effects meta-analysis of outcomes, subgroup analyses and meta-regression will be conducted. If not appropriate, narrative synthesis and ‘levels of evidence’ assessment will be completed.Ethics and disseminationEthical approval is not required as primary data will not be collected. The completed systematic review will be disseminated in a peer-reviewed journal, at conferences and contribute towards the lead author’s PhD thesis.PROSPERO registration numberCRD42019131659.

ABSTRACT Vitamin A (VA) is an essential nutrient often lacking in the diets of people in developing countries. Accurate biomarkers of VA status are vital to inform public health policy and monitor interventions. The relative dose-response (RDR) and modified-RDR (MRDR) tests are semi-quantitative screening tests for VA deficiency that have been used in Demographic and Health Surveys and VA intervention studies. A systematic review and meta-analysis of sensitivity and specificity were conducted to summarize the physiological evidence to support the RDR tests as methods to assess VA status and investigate the impact of different pathological and physiological states on the tests. A total of 190 studies were screened for inclusion, with 21 studies comparing the RDR tests with the gold-standard biomarker, liver VA concentration (68% and 80% sensitivity and 85% and 69% specificity for the RDR and MRDR, respectively). Nearly all studies with VA interventions in VA-deficient populations demonstrated a response of the tests to VA intake that would be expected to improve VA status. The impacts of chronic liver disease, protein malnutrition, age, pregnancy and lactation, infection and inflammation, and various other conditions were examined in 51 studies. The RDR and MRDR tests were reported to have been used in 39 observational studies, and the MRDR has been used in at least 6 national micronutrient surveys. The RDR and MRDR are sensitive tests for determining population VA status and assessing VA interventions. Although they are robust to most physiological and pathological states, caution may be warranted when using the tests in neonates, individuals with chronic liver disease, and those with protein or iron malnutrition. Research on further improvements to the tests to increase accessibility, such as sampling breast milk instead of blood or using intramuscular doses in subjects with malabsorption, will allow wider adoption. This review was registered with PROSPERO as CRD42019124180.

Abstract Background hip replacement is a satisfactory salvage procedure for failed fracture treatment despite the increased operative difficulty. Objectives the purpose of this systematic review and meta-analysis was to review and study literature regarding conversion arthroplasty in patients with failed internal fixation of intertrochanteric fractures to evaluate the results, technical problems and complications, as well as the impact of different variable factors and age. associated with hip arthroplasty and to evaluate the functional outcomes and complications.. Materials and Methods A systematic review of 3 databases (PubMed, Cochrane, and Embase) was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria were English-language studies that reported complications or functional outcomes after failed fixation of IT fractures with hip arthroplasty in adult subjects (&gt;18 years of age). Results About 2041 articles were found using search keywords as shown in PRISMA flow chart, By filtration and screening of the title and exclusion of unrelated articles, about 109 articles were found, By applications of all inclusion and exclusion criteria, only 8 articles were fit to undergo this meta-analysis. Conclusion So this study showed a significant improvement in functional outcome of hip arthroplasty after failed intertrochanteric fixations despite the relative complication rate of this procedure.

Objectives: Changes in airflow dynamics after nasal surgery may have implications on voice quality. Multiple studies have evaluated the impact of nasal surgery on voice using heterogeneous outcome measures. We aim to systematically review the impact of nasal surgery on voice quality. Methods: Our study design was a systematic review with meta-analyses. A literature search of PubMed, Ovid, Cochrane from 1997 to 2017 was performed. Inclusion criteria included English language studies containing original data on nasal surgery and voice. Two investigators independently reviewed all manuscripts and performed a comprehensive quality assessment. Meta-analysis was completed on quantitative voice measurements. Results: Of 463 identified, 19 studies with 692 patients fulfilled eligibility. Nasal surgeries performed included endoscopic sinus surgery (11/20), septoplasty (11/20), rhinoplasty (2/20), and turbinate reduction (2/20). Voice outcomes measured included nasalance (8/20), fundamental frequency (11/20), jitter (10/20), shimmer (10/20), harmonic to noise ratio (HRN) (8/20), formants (5/20), and voice handicap index (VHI) (4/20). Voice examinations were assessed preoperatively and 1 to 30 months postoperatively. Meta-analysis revealed statistically significant changes in nasalance, ( P < .01) 1 month postoperatively; there was no significant difference in nasalance at 6 months postoperatively. All other variables analyzed revealed no statistically significant differences. Five of nine studies showed majority of patients did not notice subjective change in voice after surgery, but with high heterogeneity of measurements. Conclusions: There may be a short-term increase in nasalance that resolves at longer follow-up, but there seem to be no other objective changes in voice. There may be subjective changes after surgery, but require further study to evaluate.
