Whey protein and vitamin D supplementation in institutionalized older adults: A randomized trial.

Background: The increase in life expectancy and in the number of individuals over 60 years old brings new demands to health professionals and services based on the physiological changes that occur in this population. The aging process results in changes in body composition, increasing body fat and reducing muscle mass, in addition to a reduction in bone mass. Aim: The aim of this study was to examine the effect of whey protein and vitamin D supplementation on body composition and skeletal muscle in older adults living in long-term care facilities. Methods: This study is a double-blind randomized controlled trial. Thirty older adults (>60 years old) were randomized and allocated in three groups: group receiving resistance training and supplementation receiving resistance training, whey protein and vitamin D; group received resistance and placebo training receiving resistance training and placebo, and control group without any intervention. Body composition was measured by dual-energy X-ray absorptiometry at baseline, 12 weeks, and 24 weeks. Results: The mean age was 74.87 (± 8.14) years. A significant difference (p = 0.042) was observed between the group receiving resistance training and supplementation and control groups in relation to lean mass increase (kg) at 24 weeks. After 24 weeks of intervention, there was a significant increase in Relative index of muscle mass for the two groups that underwent resistance training, group received resistance and placebo training (p = 0.042) and group receiving resistance training and supplementation (p = 0.045), in relation to the control. Conclusion: Combined supplementation of whey protein and vitamin D with resistance training can significantly improve lean mass, total mass, and relative index of muscle mass in institutionalized older adults.

Effectiveness of melatonin adjuvant treatment in cisplatin to prevent depletion of ovarian follicles in mice: systematic review†.

INTRODUCTION: Cisplatin-based chemotherapy is the standard cancer therapy; however, this treatment causes depletion of ovarian follicles in women of reproductive age. Adjuvant treatment with melatonin can protect the ovaries from oxidative stress, reducing the side effects of chemotherapy. The objective was to evaluate the effects of the use of melatonin on the ovarian follicles of mice treated with cisplatin. METHODOLOGY: A systematic review was performed. The search strategy used the terms: "cisplatin", "melatonin," and "ovarian". MEDLINE EMBASE, Cochrane Library, and gray literature (Google Scholar) were used as databases. The search was limited to experimental studies, performed on animals, with no language restrictions. RESULTS: The search identified 30 studies and 5 primary studies, published between 2016 and 2021, and met the inclusion criteria, with a total of 115 mice. For the p-FOX3a/FOXO3a pathway, the meta-analysis showed a standard mean difference (SMD) of -4.79 (95% CI -6.16 to -3.42; P < 0.00001, two studies, 38 mice; I2 = 0%). For the p-PTEN pathway, the meta-analysis showed an SMD of -1.65 (95% CI -2.71 to -0.59; P = 0.002, two studies, 38 mice; I2 = 47%). CONCLUSION: Melatonin variation in efficacy varies according to the dose used in mice previously exposed to cisplatin. However, melatonin was able to alter the p-PTEN and p-FOX3a/FOXO3a pathways.

Correspondence: semen parameters in men who recovered from covid-19 - a systematic review and meta-analysis.

A recent systematic review with meta-analysis performed by Tiwari et al. (Middle East Fertil Soc J 26:44, 2021) suggested that coronavirus disease 2019 (COVID-19) affects both semen parameters and sexual hormones. However, we have observed a few inconsistencies in their systematic review methods and their synthesis of results (meta-analysis), which would have impacted their results.

LEVELS OF SALIVARY CORTISOL IN ADULTS AND CHILDREN WITH BRUXISM DIAGNOSIS: A SYSTEMATIC REVIEW AND META-ANALYSIS.

OBJECTIVES: To evaluate the levels of salivary cortisol in adults and children diagnosed with bruxism. METHODS: A search strategy was developed using the following terms: "cortisol", "bruxism" and "sleep bruxism". These were searched in databases: Medline, Embase, Scopus, Cochrane, Web of Science, LILACS and gray literature, for studies published until May 2020. RESULTS: We obtained a total of six primary studies, involving 854 participants, who met the criteria and were included in the present study. The analysis cortisol levels shows a significant difference favourable to the control group 1.10 (95% CI: 0.68-1.53), showing that patients with bruxism have higher values of salivary cortisol. Heterogeneity of I²â€¯= 4% (P = .31). CONCLUSIONS: It was concluded that despite the different methodologies adopted for the collection and analysis of salivary content, this review found significant results of higher levels of salivary cortisol in adult patients with bruxism.

Effect of exercise on epicardial adipose tissue in adults: a systematic review and meta-analyses.

According to previous epidemiological studies, we can reduce the thickness of epicardial fat and improve cardiovascular risk factors through exercise, and the changes may depend on the form of exercise. We systemically reviewed published studies that evaluated exercise intervention on epicardial adipose tissue (EAT) levels. We included randomized controlled trials (RCTs) comparing one exercise with another exercise or diet for the treatment to reduce EAT. We used fixed effects models for meta-analyses; effects of exercise on outcomes were described as mean differences (MD) or standardized difference of means (SMD) was used, their 95% confidence intervals (CI). Five RCTs were included (n = 299), 156 in exercise group and 143 in the control. In comparison to the control group, exercise significantly reduced EAT (SMD - 0.57, 95%CI - 0.97 to - 0.18) and waist circumference (MD - 2.95 cm, 95%CI - 4.93 to - 0.97). Exercise did not have an effect on BMI (MD - 0.23 kg/m2, 95%CI - 0.73 to 0.27), weight (MD - 0.06 kg, 95%CI - 1.46 to 1.34), or HDL (SMD 0.26, 95%CI - 0.06 to 0.57).VO2 was significantly increased by exercise (SMD 1.58, 95%CI 1.17 to 1.99). Risk of bias was high for 3 studies, and GRADE quality of evidence was very low to moderate. Exercise reduced epicardial adipose tissue and waist circumference, and did not have effect on weight, BMI, or HDL. Newer trials with better design and methods are necessary to improve the quality of the evidence. PROSPERO registration number (CRD42018096581).

Postmortem evidence of brain inflammatory markers in bipolar disorder: a systematic review.

Bipolar disorder (BD) is a chronic affective disorder with extreme mood swings that include mania or hypomania and depression. Though the exact mechanism of BD is unknown, neuroinflammation is one of the numerous investigated etiopathophysiological causes of BD. This article presents a systematic review of the data regarding brain inflammation evaluating microglia, astrocytes, cytokines, chemokines, adhesion molecules, and other inflammatory markers in postmortem BD brain samples. This systematic review was performed according to PRISMA recommendations, and relevant studies were identified by searching the PubMed/MEDLINE, PsycINFO, EMBASE, LILACS, IBECS, and Web of Science databases for peer-reviewed journal articles published by March 2019. Quality of included studies appraised using the QUADAS-2 tool. Among the 1814 articles included in the primary screening, 51 articles measured inflammatory markers in postmortem BD brain samples. A number of studies have shown evidence of inflammation in BD postmortem brain samples. However, an absolute statement cannot be concluded whether neuroinflammation is present in BD due to the large number of studies did not evaluate the presence of infiltrating peripheral immune cells in the central nervous system (CNS) parenchyma, cytokines levels, and microglia activation in the same postmortem brain sample. For example, out of 15 studies that evaluated microglia cells markers, 8 studies found no effect of BD on these cells. Similarly, 17 out of 51 studies evaluating astrocytes markers, 9 studies did not find any effect of BD on astrocyte cells, whereas 8 studies found a decrease and 2 studies presented both increase and decrease in different brain regions. In addition, multiple factors account for the variability across the studies, including postmortem interval, brain area studied, age at diagnosis, undergoing treatment, and others. Future analyses should rectify these potential sources of heterogeneity and reach a consensus regarding the inflammatory markers in postmortem BD brain samples.

Hyaluronic Acid in Postmenopause Vaginal Atrophy: A Systematic Review.

BACKGROUND: The decline in postmenopausal serum estrogen concentration results in several changes in the vulvovaginal and vesicourethral areas, resulting in the genitourinary syndrome of menopause, including symptoms such as vaginal atrophy. AIM: To evaluate the effects of hyaluronic acid in vaginal atrophy. METHODS: A search strategy was developed using the following terms: "Hyaluronic Acid vaginal gel," "vaginal estrogens," "Vaginitis, Atrophic," and "Postmenopause." This strategy was used in major databases such as MEDLINE, EMBASE, Scopus, Cochrane library, Web of Science, Virtual Health Library (BVS), Congress Abstracts, and Gray Literature (Google Scholar and British Library) for studies published until June 2020. OUTCOMES: A systematic review was carried out to assess the results of atrophic vaginitis/vaginal dryness, dyspareunia, vaginal pH, and cell maturation of the studies found by the search strategy. RESULTS: A total of 833 studies were identified, 528 studies were directed for reading titles and abstracts, and 515 were excluded for not meeting the selection criteria. A total of 13 studies were selected for reading the full text. 5 primary studies involving 335 women met the criteria and were included. The studies were published between the years 2011 and 2017. It was not possible to perform meta-analysis owing to the substantial heterogeneity present in the studies. The results presented suggest that treatment with hyaluronic acid, when compared with the use of estrogens, does not present a significant difference in the results obtained for the outcomes: epithelial atrophy, vaginal pH, dyspareunia, and cell maturation. CLINICAL TRANSLATION: Hyaluronic acid appears to be an alternative to non-hormonal treatments for the signs of vaginal atrophy and dyspareunia. STRENGTHS & LIMITATIONS: The analysis of the studies in this systemic review suggests that hyaluronic acid has efficacy similar to vaginal estrogens for the treatment of the signs of vaginal atrophy and dyspareunia. However, the included studies measured the data in different ways, causing the performance of meta-analysis to be impaired. CONCLUSION: The comparisons presented suggest that hyaluronic acid has a profile of efficacy, safety, and tolerability comparable with vaginal estrogens for the treatment of symptoms of vaginal atrophy. It is a possible alternative for women who cannot use hormonal treatment. dos Santos CCM, Uggioni MLR, Colonetti T, et al. Hyaluronic Acid in Postmenopause Vaginal Atrophy: A Systematic Review.

Evaluation of the arachidonic acid pathway in bipolar disorder: a systematic review.

Bipolar disorder (BD) is a mood psychiatric disorder described by changes between depressive, hypomanic, or manic episodes. The aimed of the present study was evaluated possible changes in the AA pathway in BD through a systematic review of observational studies. A search in the electronic databases was proceeded, on Cochrane Library, MEDLINE, EMBASE, PsycINFO, Google Scholar and the British Library for studies published until August 2020. A search strategy was developed using the terms: "Bipolar Disorder" and "Phospholipase A2" or "Arachidonic Acids" or "Cyclooxygenase 2" or "Prostaglandins E" as text words and Medical Subject Headings (i.e., MeSH and EMTREE). Seven primary studies were included in the systematic review, with a total of 246 BD patients, 20 depression patients, and 425 heathy controls (HC). The studies showed contradictory results in the AA and PLA2, no primary articles with COX and PGE2 assessments were included in this review. According to the Newcastle-Ottawa quality score scale (NOS), our systematic review presented high quality. The investigation of the inflammatory pathway of AA still needs further investigation and evidence, given the growing number of studies suggesting the efficacy of anti-inflammatory drugs as adjunctive therapy in the pharmacological treatment of BD.

Accuracy of Messenger RNA Human Papillomavirus Tests for Diagnostic Triage of Minor Cytological Cervical Lesions: A Systematic Review and Meta-Analysis.

OBJECTIVES: The main objective of this systematic review and meta-analysis is to specify the accuracy of messenger RNA human papillomavirus (HPV) tests among women with previous minor cervical lesion cytology to detect high-grade squamous intraepithelial lesions (CIN2+ and CIN3+) compared with a histopathological reference standard. The secondary objective is to compare messenger RNA HPV test accuracies and the DNA high-risk HPV test among these women. METHODS: Eligible studies were identified by searching the electronic databases with medical subject headings. MAIN RESULTS: Among the 2052 studies identified, 20 primary studies were included. Two tests were mainly identified: Aptima and PreTect HPV-Proofer. Aptima, with 10 studies, had better performance, considering atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion together, with a pooled sensitivity of 90.5% (95% confidence interval [CI], 88.1-92.6) and specificity of 55.1% (95% CI, 53.5-56.8) for CIN2+. For the ASC-US sample, Aptima had a pooled sensitivity of 90.1% (95% CI, 87.1-92.7) and specificity of 59.3% (95% CI, 57.5-61.1). CONCLUSIONS: Messenger RNA HPV tests, mainly Aptima assay, can be recommended to triage women with ASC-US and low-grade squamous intraepithelial lesion because it has higher specificity with a small loss of sensitivity than Hybrid Capture 2 assay; this finding is promising as a means to reduce the overmanagement of minor cytological abnormalities.

Accuracy of Anal Cytology for Diagnostic of Precursor Lesions of Anal Cancer: Systematic Review and Meta-analysis.

BACKGROUND: Anal canal carcinoma is relevant because it commonly occurs in high-risk groups, and its incidence has been increasing. OBJECTIVE: This study evaluated the accuracy of anal cytology in the screening of precursor lesions of anal cancer, compared with histopathologic examination as the reference, in all subjects and in men who have sex with men, HIV-infected men and women, and men who have sex with men and HIV-infected subgroups. DATA SOURCES: The data included studies identified in the MEDLINE, Latin American and Caribbean Health Sciences, Cochrane Library, and Embase electronic databases, as well as in the grey literature. The search terms included anal cancer, anal dysplasia, anal intraepithelial neoplasia, screening, and anal cytology. STUDY SELECTION: After excluding studies with no histopathological data and those with duplicate and missing data, 34 primary studies were included. INTERVENTION: Cytology of anal smears was studied. MAIN OUTCOME MEASURES: Sensitivity, specificity, diagnostic OR, and area under the curve were measured. RESULTS: A total of 5093 patients were included. The pooled sensitivity of anal cytology was 85.0% (95% CI, 82.0%-87.0%) and pooled specificity was 43.2% (95% CI, 41.4%-45.1%) for the detection of anal intraepithelial neoplasia grade 2 or worse versus anal intraepithelial neoplasia grade 1 and normal when measuring all subjects. The accuracy of anal cytology was higher in the men who have sex with men and HIV-infected and men who have sex with men only subgroups. LIMITATIONS: This study was limited by its specificity. CONCLUSIONS: The study results support the hypothesis that cytology is a good test for the screening of anal cancer.

Accuracy of neutrophil gelatinase-associated lipocalin for acute kidney injury diagnosis in children: systematic review and meta-analysis.

OBJECTIVE: To estimate the accuracy of Neutrophil Gelatinase-Associated Lipocalin (NGAL) as a biomarker for acute kidney injury (AKI) in children. METHODS: A systematic review of the literature was performed. The review protocol was registered at PROSPERO (CRD 42015024153). We conducted searches in the following databases: Medline (PubMed), LILACS (BVS), SCOPUS (Elsevier), Embase (OVID), Cochrane Central Register of Controlled Trials (CENTRAL), Biomed Central, and ISI Web of Science, from January 1990 to October 2016. For inclusion, studies measured NGAL levels in plasma and urine for AKI in children. For each study, 2 × 2 contingency tables were developed. For statistical analysis we calculated the sensitivity, specificity and diagnostic odds ratio. For methodological assessment, we used Quality Assessment of Diagnostic Accuracy Studies-2. Software used for analysis was Stata 14, and RevMan 5.3. RESULTS: In total 13 studies were analyzed, which included 1629 children. For urinary NGAL, the pooled sensitivity was 0.76 (95% CI 0.62-0.85) and a pooled specificity 0.93 (95% CI 0.88-0.96). The diagnostic odds ratio (DOR) for the detection of AKI was 43 (95% CI 16-115) and the Area under the curve (AUC) was 0.94 (95% CI 0.92-0.96). For plasma NGAL the combined sensitivity was 0.80 (95% CI 0.64-0.90) and a combined specificity was 0.87 (95% CI 0.74-0.94). The DOR was 26 (95% CI 8.0-82) and AUC was 0.90 (95% CI 0.87-0.94) for the detection of AKI in children. CONCLUSION: The data suggest that NGAL levels can be an important biomarker for the early detection of AKI in children.

Laparoscopy versus laparotomy for FIGO stage I ovarian cancer.

BACKGROUND: This is an updated version of the original review that was first published in the Cochrane Database of Systematic Reviews 2008, Issue 4. Laparoscopy has become an increasingly common approach to surgical staging of apparent early-stage ovarian tumours. This review was undertaken to assess the available evidence on the benefits and risks of laparoscopy compared with laparotomy for the management of International Federation of Gynaecology and Obstetrics (FIGO) stage I ovarian cancer. OBJECTIVES: To evaluate the benefits and harms of laparoscopy in the surgical treatment of FIGO stage I ovarian cancer (stages Ia, Ib and Ic) when compared with laparotomy. SEARCH METHODS: For the original review, we searched the Cochrane Gynaecological Cancer Group Trials (CGCRG) Register, Cochrane Central Register of Controlled Trials (CENTRAL 2007, Issue 2), MEDLINE, Embase, LILACS, Biological Abstracts and CancerLit from 1 January 1990 to 30 November 2007. We also handsearched relevant journals, reference lists of identified studies and conference abstracts. For the first updated review, the search was extended to the CGCRG Specialised Register, CENTRAL, MEDLINE, Embase and LILACS to 6 December 2011. For this update we searched CENTRAL, MEDLINE, and Embase from November 2011 to September 2016. SELECTION CRITERIA: Randomised controlled trials (RCTs), quasi-RCTs and prospective cohort studies comparing laparoscopic staging with open surgery (laparotomy) in women with stage I ovarian cancer according to FIGO. DATA COLLECTION AND ANALYSIS: There were no studies to include, therefore we tabulated data from non-randomised studies (NRS) for discussion as well as important data from other meta-analyses. MAIN RESULTS: We performed no meta-analyses. AUTHORS' CONCLUSIONS: This review has found no good-quality evidence to help quantify the risks and benefits of laparoscopy for the management of early-stage ovarian cancer as routine clinical practice.

Accuracy of serum human epididymis protein 4 in ovarian cancer diagnosis: a systematic review and meta-analysis.

OBJECTIVE: A systematic review was performed to estimate the accuracy of human epididymis protein 4 (HE4) assay in the diagnosis of ovarian tumors. METHODS: A comprehensive search of the MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials, IBECS, BIOSIS, Web of Science, SCOPUS, congress abstracts, and Grey literature (Google scholar; British Library) from January 1990 to April 2013 was conducted. Studies that evaluated HE4 levels for the diagnosis of ovarian tumors and compared them with paraffin-embedded sections as the diagnostic standard were included. RESULTS: Forty-five studies were analyzed, which included 10,671 women and 3946 ovarian cancer cases. The pooled sensitivity for the diagnosis of borderline tumors or ovarian cancer was 78% (95% confidence interval, 77%-79%), and the specificity was 86% (95% confidence interval, 85%-87%). Summary receiver operating characteristic curves were constructed. For malignant and borderline ovarian tumors versus benign lesions, the area under the curve was 0.916. Besides the overall analysis, stratification was performed in premenopause and postmenopause, early and late stages, and for accuracy by enzyme-linked immunosorbent assay and chemiluminescence microparticle immuno assay. CONCLUSIONS: A HE4 level is a useful preoperative test for predicting the benign or malignant nature of pelvic masses.

Evaluation of N-acetyl-ß-D-glucosaminidase as a prognostic marker for diabetic nephropathy in type 2 diabetics: systematic review and meta-analysis.

OBJECTIVE: This review aimed to assess the utility of urinary N-acetyl-ß-D-glucosaminidase (uNAG) as a prognostic biomarker for nephropathy in patients with type 2 diabetes mellitus. METHODS: The search for relevant studies was conducted across multiple databases, including PubMed (Medline), EMBASE, LILACS, CENTRAL, IBECS, and gray literature. We employed a random effects model to calculate the standardized mean difference and 95% confidence interval. Furthermore, we assessed heterogeneity using Cochrane's Q test and Higgins' I2 statistics. RESULTS: This review included a total of 16 articles involving 1669 patients, with 13 being case-control studies and three being cohorts. The meta-analysis conducted across all studies revealed significant heterogeneity. However, subgroup analysis of four studies indicated that an increase in uNAG among normoalbuminuric patients was associated with the development of macroalbuminuria (DMP = - 1.47; 95% CI = - 1.98 to 0.95; p < 0.00001; I2 = 45%). Conversely, it did not demonstrate effectiveness in predicting the development of microalbuminuria (DMP = 0.26; 95% CI = - 0.08 to 0.60; p = 0.13; I2 = 17%). CONCLUSIONS: Elevated uNAG levels in normoalbuminuric patients may indicate an increased risk for the development of macroalbuminuria, but not microalbuminuria. However, the high heterogeneity observed among the studies highlights the necessity for further research to validate these findings.

The effects of academic unprofessional behaviour on disciplinary action by medical boards: Systematic review and meta-analysis.

OBJECTIVE: The objective of this study is to evaluate the association of disciplinary actions by regulatory councils and unprofessional behaviour during medical graduation. METHODS: A search strategy was developed using the terms: 'physicians', 'disciplinary action', 'education', 'medical', 'undergraduate' and their synonyms, subsequently applied to the electronic databases MEDLINE, Embase, Cochrane Library, LILACs and grey literature, with searches up to November 2023. The risk of bias was assessed using the Newcastle-Ottawa scale and statistical analysis was performed using the RevMan software. RESULTS: A total of 400 studies were found in the databases, and 15 studies were selected for full-texting reading. Four studies met the inclusion criteria and were included, bringing together a total of 3341 evaluated physicians. Three studies were included in the meta-analysis, showing a greater chance of disciplinary actions among physicians who exhibited unprofessional behaviour during medical graduation (OR: 2.54; 95%CI: 1.87-3.44; I2: 0%; P < 0.0001; 3077 participants; physicians with disciplinary action: 107/323; control physicians: 222/2754). CONCLUSIONS: There is a statistically significant association between unprofessional behaviour during medical undergraduate study and subsequent disciplinary actions by Medical Councils. The tools for periodic assessments of student behaviour during undergraduate studies can be a perspective for future studies aimed at reducing disciplinary actions among physicians.

Prevalence of cognitive impairment and associated factors in older people.

BACKGROUND: Older people are the fastest-growing age group, with the highest risk of cognitive impairment. This study assessed the prevalence and associated factors with cognitive impairment in community-dwelling older people. METHODS: Older people were interviewed and accomplished through sociodemographic and health questionnaires. The quantitative variables were described by mean and standard deviation or median and interquartile range. The significance level adopted was 5 % (p < 0.05). The association between the quantitative variables was evaluated using the Pearson or Spearman correlation coefficients. RESULTS: The research population comprised 165 long-lived adults aged ≥80. The youngest one was 80, and the oldest one was 94 years old. The participants were 84.8 ± 3.6 years old, female (63 %) with a mean of education of 2.9 ± 1.8 years. A poor performance in the Mini-Mental State Examination (MMSE) was found in 58 (35.2 %) individuals when adjusted for educational level. After adjustment for confounding factors, body mass index (BMI) (p = 0.09), total older adults' income (up to 1 minimum wage [mw], p = 0.023; over 1 to 2 mw, p = 0.023), functional disability (Moderate dependence 75 %, p = 0.038; Moderate dependence 50 %, p = 0.081; Moderate dependence 25 %, p = 0.054), and the anxiety scale (p = 0.032), remained associated with cognitive impairment. CONCLUSIONS: This study showed that BMI, total older adults' income, functional disability, and anxiety are related to cognitive impairment in long-lived adults. This study has some limitations, such as the fact that it is a cross-sectional study, the reduced number of individuals, and the fact that there were no comparisons among different ages and populations.

DNA high-risk HPV, mRNA HPV and P16 tests for diagnosis of anal cancer and precursor lesions: a systematic review and meta-analysis.

Background: Anal cancer prevention has two critical points: the incidence rate is several fold higher for some groups, such as people living with human immunodeficiency virus (HIV) and men who have sex with men (MSM), and there is not a well-defined guideline for its screening. This systematic review evaluates the accuracy of DNA HRHPV (high-risk human papillomavirus), mRNA HPV, DNA HPV16 isolated and p16 staining biomarkers in anal canal smears for identifying anal intraepithelial neoplasia (AIN) 2 or 3, summarised as anal high-grade squamous intraepithelial lesions (aHSIL), and cancer. Methods: We searched the MEDLINE, Cochrane Library and Embase electronic databases as well as Grey literature to identify eligible papers published up to 31st July 2022. This systematic review and meta-analysis included observational studies comparing biomarker tests to histopathology after HRA (High-resolution Anoscopy) as a reference standard. We (ACM, TF) analysed studies in which patients of both sexes were screened for anal cancer using DNA HRHPV, mRNA HPV, DNA HPV16 and/or p16 biomarkers. The analysis was performed in pairs, for instance AIN2 or worse (AIN2+) vs. AIN1, HPV infection and normal (AIN1-). PROSPERO CRD42015024201. Findings: We included 21 studies with 7445 patients. DNA HR HPV showed a higher sensitivity 92.4% (95% CI 84.2-96.5), specificity 41.7% (95% CI 33.9-44.9) and AUC 0.67, followed by the mRNA HPV test, with a sensitivity 77.3% (95% CI 73.2%-80.9%), specificity 61.9% (95% CI 56.6-66.9) and AUC 0.78. DNA HPV16 showed higher specificity 71.7% (95% CI 55.3-83.8), followed by p16 test, 64.1% (95% CI 51.0-75.4); Sensitivity of DNA HPV16 was 53.3% (95% CI 35.4-70.3) and AUC 0.69, while p16 had a sensitivity of 68.8% (95% CI 47.9-84.1) and AUC 0.74. Subgroup analysis of MSM with HIV, with 13 studies and 5123 patients, showed similar accuracy, with a bit higher sensitivities and lower specificities. Considering the measure of the total between-study variability, mRNA HPV tests showed the smallest area of the 95% prediction ellipse, 6.0%, influenced by the low logit sensitivity, 0.011. All other groups of tests exceed 50% prediction ellipse area, which represent a high heterogeneity. Interpretation: Our findings suggested that DNA HR HPV can be a useful tool for screening for aHSIL and anal cancer if followed by biomarker with a higher specificity. As an isolated test, mRNA HPV had better performance. Funding: There was no funding source for this study.

Climate change and mental health of Indigenous peoples living in their territory: a concept mapping study.

Background: The alarming increase in annual deforestation rates has had devastating consequences in climate change, and it is affecting Indigenous people, who depend entirely on the land for survival and has also weakened the rainforest's crucial role in stabilizing the global climate. Recognizing and respecting Indigenous people's needs and social, economic, and historical conditions influence health and healthcare. This study aimed to conduct online concept mapping workshops with university students to identify perceived important and feasible actions for improving the mental health of Indigenous people living in their territory in association with climate change. Methods: Concept mapping, a participatory mixed methodology, was conducted virtually with 20 Indigenous students at two universities in Brazil. A focus prompt was developed from consultations with Indigenous stakeholders and read-"To improve the mental health of Indigenous peoples in their territory during climate change crises, it is necessary to…." Results: University students organized 42 unique statements in 6 clusters that cover a wide range of topics: family support, 0.68 (SD 0.19); respect and understanding, 0.37 (SD 0.08); improvement actions, 0.52 (SD 0.07); public policies in favor of Indigenous people's mental health, 0.24 (0.09); health actions, 0.15 (SD 0.08); Indigenous training in health and its importance in improving mental health 0.32 (SD 0.07). Conclusion: These clusters range from community initiatives, public policies, health actions, and strengthening professional services in Indigenous communities. These all provide numerous concrete ideas for developing interventions designed to address mental health challenges associated with climate change.

Gut and Vaginal Microbiota in the Endometriosis: Systematic Review and Meta-Analysis.

Background: Endometriosis is a clinical condition associated with genetic, endocrine, and immunological factors, present in 6 to 10% of women of reproductive age. Currently, the human microbiota has been studied and associated with the evolution of diseases due to its influence on pathogenesis, indicating that changes in the colonization of microorganisms in the genitourinary and gastrointestinal systems can promote physiological changes that can trigger inflammatory and immunological processes and hormonal dysregulation, which can be linked to endometriosis. Thus, this systematic review and meta-analysis evaluated microbiota changes in women with endometriosis. Methods: The following electronic databases were searched up to April 2022: Medline, Embase, Web of Science, Cochrane Library, and gray literature (Google Scholar), using the keywords "dysbiosis", "microbiome" and "endometriosis", combined with their synonyms. The observational studies conducted with women diagnosed with endometriosis and women without endometriosis as controls were included. For the analyses, a standard mean difference with a 95% confidence interval was used using RevMan software (version 5.4), and for methodological quality assessment, the Newcastle-Ottawa scale was used. Results: A total of 16 studies were found in the literature assessing the composition of the microbiota in women with endometriosis, and no significant difference were found for changes in alpha diversity analysis in gut microbiota (SMD = -0.28; 95% CI = -0.70 to 0.14; P = 0.19; I2 = 52%; four studies, 357 participants) or vaginal microbiota (SMD = -0.68; 95% CI = -1.72 to 0.35; P = 0.19; I2 = 66%; two studies, 49 participants). Conclusion: In intestinal and vaginal samples from women with endometriosis, alpha-diversity did not present a significant difference when compared to the control population. However, each study individually showed a possible relationship between the female microbiota and endometriosis. This trial is registered with CRD42021260972.
