Meta-Analysis Review
BACKGROUND
Reduction mammaplasty (RM) has become established as the standard effective method for treating macromastia, but reports on the risk factors that predispose to postoperative complications have been conflicting. This meta-analysis aimed to pool the available data to identify predictors of complications following RM.
METHODS
The PubMed, Web of Science, Embase, and Cochrane databases were screened from inception to 1 Jan 2022, and studies were included based on predefined criteria. The perioperative risk factors BMI, smoking, age, diabetes, radiation therapy, and tissue resection weight were extracted and their correlation with complications assessed.
RESULTS
A total of 40 studies comprising of 5908 patients were included. BMI ≥ 30kg/m (OR = 1.65, 95% CI 1.35-2.02; p < 0.01) and ≥ 40 kg/m (OR = 1.97, 95% CI 1.26-3.08; p < 0.01), smoking (OR = 2.57, 95% CI 2.01-3.28; p < 0.01), diabetes (OR = 2.21, 95% CI 1.19-4.07; p < 0.05), a unilateral resection weight ≥ 1000 g (OR = 1.76, 95% CI 1.02-3.05; p < 0.05), and radiation therapy (OR = 11.11, 95% CI 2.01-3.28; p < 0.01) were associated with higher rates of postoperative complications. Obese patients (BMI ≥ 30 kg/m) were more likely to experience fat necrosis (OR = 3.00, 95% CI 1.37-6.57; p < 0.01) and infection (OR = 1.66, 95% CI 1.15-2.40; p < 0.05). Smokers had a 2.03 times higher risk of infection (95% CI 1.24-3.31; p < 0.01) and 2.34 times higher risk of dehiscence (95% CI 1.38-3.98; p < 0.01). No association between complication occurrence and age 40 or 50 years or total tissue resection weight ≥ 1000 g was identified.
CONCLUSIONS
This meta-analysis provides evidence that obesity, smoking, diabetes, unilateral resection weight ≥ 1000 g, and preoperative radiation therapy predispose to complication occurrence in RM. This information can optimize the ability of surgeons to provide preoperative patient education, perioperative assessment, and postoperative care planning.

BACKGROUND
Exercise training performed at maximal fat oxidation (FATmax) is an efficient non-pharmacological approach for the management of obesity and its related cardio-metabolic disorders.
OBJECTIVES
Therefore, this work aimed to provide exercise intensity guidelines and training volume recommendations for maximizing fat oxidation in patients with obesity.
METHODS
A systematic review of original articles published in English, Spanish or French languages was carried out in EBSCOhost, PubMed and Scopus by strictly following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. Those studies that analyzed maximal fat oxidation (MFO) and FATmax in patients with obesity (body fat > 25% for men; > 35% for women) by calculating substrate oxidation rates through indirect calorimetry during a graded exercise test with short-duration stages (< 10 min) were selected for quantitative analysis. The accuracy of relative oxygen uptake (% peak oxygen uptake [%[Formula: see text]O]) and relative heart rate (% peak heart rate [%HR]) for establishing FATmax reference values was investigated by analyzing their intra-individual and inter-study variation. Moreover, cluster analysis and meta-regression were used for determining the influence of biological factors and methodological procedures on MFO and FATmax.
RESULTS
Sixty-four manuscripts were selected from 146 records; 23 studies only recruited men (n = 465), 14 studies only evaluated women (n = 575), and 27 studies included individuals from both sexes (n = 6434). The majority of the evaluated subjects were middle-aged adults (aged 40-60 y; 84%) with a poor cardiorespiratory fitness (≤ 43 mL·kg·min; 81%), and the reported MFO ranged from 0.27 to 0.33 g·min. The relative heart rate at FATmax (coefficient of variation [CV]: 8.8%) showed a lower intra-individual variation compared with relative oxygen uptake (CV: 17.2%). Furthermore, blood lactate levels at FATmax ranged from 1.3 to 2.7 mmol·L while the speed and power output at FATmax fluctuated from 4 to 5.1 km·h and 42.8-60.2 watts, respectively. Age, body mass index, cardiorespiratory fitness, FATmax, the type of ergometer and the stoichiometric equation used to calculate the MFO independently explained MFO values (R = 0.85; p < 0.01). The MFO in adolescents was superior in comparison with MFO observed in young and middle-aged adults. On the other hand, the MFO was higher during treadmill walking in comparison with stationary cycling. Body fat and MFO alone determined 29% of the variation in FATmax (p < 0.01), noting that individuals with body fat > 35% showed a heart rate of 61-66% HR while individuals with < 35% body fat showed a heart rate between 57 and 64% HR. Neither biological sex nor the analytical procedure for computing the fat oxidation kinetics were associated with MFO and FATmax.
CONCLUSION
Relative heart rate rather than relative oxygen uptake should be used for establishing FATmax reference values in patients with obesity. A heart rate of 61-66% HR should be recommended to patients with > 35% body fat while a heart rate of 57-64% HR should be recommended to patients with body fat < 35%. Moreover, training volume must be higher in adults to achieve a similar fat oxidation compared with adolescents whereas exercising on a treadmill requires a lower training volume to achieve significant fat oxidation in comparison with stationary cycling.

Review
BACKGROUND
Multimorbidity, the coexistence of multiple chronic diseases in an individual, is highly prevalent and challenging for healthcare systems. However, its risk factors remain poorly understood.
OBJECTIVE
To systematically review studies reporting multimorbidity risk factors.
METHODS
A PRISMA-compliant systematic review was conducted, searching electronic databases (MEDLINE, EMBASE, Web of Science, Scopus). Inclusion criteria were studies addressing multimorbidity transitions, trajectories, continuous disease counts, and specific patterns. Non-human studies and participants under 18 were excluded. Associations between risk factors and multimorbidity onset were reported.
RESULTS
Of 20,806 identified studies, 68 were included, with participants aged 18-105 from 23 countries. Nine risk factor categories were identified, including demographic, socioeconomic, and behavioral factors. Older age, low education, obesity, hypertension, depression, low pysical function were generally positively associated with multimorbidity. Results for factors like smoking, alcohol consumption, and dietary patterns were inconsistent. Study quality was moderate, with 16.2% having low risk of bias.
CONCLUSIONS
Several risk factors seem to be consistently associated with an increased risk of accumulating chronic diseases over time. However, heterogeneity in settings, exposure and outcome, and baseline health of participants hampers robust conclusions.

Meta-Analysis
AIMS
The aim of this meta-analysis is to evaluate the potential correlation between obesity and overweight, and the vulnerability to urinary incontinence (UI) in women aged middle-aged and above.
METHODS
We searched PubMed, Cochrane Library, and Embase for observational studies published between the inception of the databases and April 25, 2023. A fixed-effects model was used when the P>0.1 and the I ≤ 50%. In cases where I ≥ 50% (indicating significant heterogeneity), a random-effects model was applied. For the purpose of evaluating publication bias, a funnel plot and Egger's test were used. Stata 14.0 was used for all statistical analyses.
FINDINGS
This meta-analysis includes 16 observational studies, covering29,618 individuals. The pooled analysis shows that being overweight(25 kg/m≤BMI<30kg/m) in middle-aged and elderly women is more likely to develop UI (OR=1.27; 95% CI: 1.17-1.37; I = 51.8%, P=0.013). Middle-aged and elderly women with obesity(30 kg/m≤BMI<35 kg/m) are significantly more likely to develop UI (OR=1.60; 95% CI: 1.42-1.81; I = 71.8%, P=0.000). In addition, the results indicated a higher probability of UI in middle-aged and older women with obesity class II (BMI≥35 kg/m) (OR=1.85; 95% CI: 1.59-2.16; I48.1%, P=0.103). In subgroup analysis, there is no direct relationship between the obesity in middle-aged and elderly women and an increased risk of stress urinary incontinence (SUI) (OR=1.31; 95% CI: 0.99-1.74; I = 63.7%, P=0.011). In middle-aged and elderly women with obesity are more likely to develop urgent urinary incontinence (UUI) (OR=2.11; 95% CI: 1.54-2.89; I = 80.2%, P=0.000).
CONCLUSION
In this meta-analysis, overweight and obesity are associated with an increased risk of UI in middle-aged and elderly women. Obesity and overweight are independent risk factors for UI, as demonstrated by this study.

Meta-Analysis
This systematic meta-review evaluated the effects of exercise with and without protein interventions on muscle strength and function in older adults with sarcopenic obesity. PubMed, Cochrane Database of Systematic Reviews, Cumulative Index to Nursing and Allied Health Literature, Scopus, and SPORTDiscus databases were searched through February 2021 for relevant systematic reviews and meta-analyses with aerobic, resistance, and/or combined training interventions with and without protein supplementation in older adults ≥ 65 years with sarcopenic obesity. This meta-review showed that exercise with and without protein supplementation improved body composition (i.e., decreased percentage body fat) and functional outcomes (i.e., gait speed and grip strength). Because the current literature is limited, determining the effects of exercise and combined protein supplementation in this population requires further investigation. In the meantime, protein recommendations should align with general sarcopenia recommendations. Based upon available findings, tentative exercise recommendations to optimize health outcomes in this population are proposed.

Meta-Analysis Review
OBJECTIVE
The aim of this Meta-analysis and systematic review was to perform a comprehensive assessment of the association of chronic rhinosinusitis (CRS) with overweight/obesity, leptin hormone, and its associated metabolic dysregulation.
DATA SOURCES
Ovid MEDLINE, Embase, Web of Science, and Cochrane Central Register of Controlled Trials, were searched for studies from 1946 to October 2022, using predefined syntax.
REVIEW METHODS
Outcome data for the meta-analysis were extracted on odds ratios (OR) of CRS prevalence based on the presence of overweight/obesity and mean serum leptin levels. A Meta-analysis was performed using the DerSimonian-Laird estimator to pool extracted data by the generalized inverse variance approach. Random effect models were utilized due to the small sample size. A qualitative synthesis was performed on articles that did not meet the inclusion criteria for the Meta-analysis.
RESULTS
Thirty-six studies met the systematic review inclusion criteria out of 1113 articles screened. A total of 6 studies were included in the pooled Meta-analysis of the various outcome variables. Our pooled meta-analysis observed a positive association between overweight/obesity and the prevalence of CRS (OR = 1.33, 95% confidence interval [CI]: 1.17-1.51). The pooled ratio of the means analysis of the mean serum leptin levels between CRS with nasal polyposis and control patients was 2.21 (95% CI: 1.45; 3.36).
CONCLUSION
Our pooled Meta-analysis indicates a positive association between overweight/obesity and CRS. Future prospective studies are needed to explore the association between CRS and obesity with an understanding of potential confounding comorbidities, including studies focused on assessing the underlying immunologic mechanism of this association.

Meta-Analysis Review
The relationship between anthocyanin intake and obesity-related inflammatory markers remains unclear in existing research. To investigate this, we hypothesized that anthocyanin supplementation could reduce plasma concentrations of inflammatory markers, including C-reactive protein (CRP), tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), vascular cell adhesion molecule-1, and other cytokines in obesity. We conducted a systematic search of PubMed, Web of Science, Scopus, SinoMed, and other related literature and identified 16 randomized controlled trials that met our inclusion criteria. Our findings showed that anthocyanin intake was significantly associated with a reduction in vascular cell adhesion molecule-1 mean plasma concentrations (-53.56 ng/mL; 95% confidence interval [CI], -82.10 to -25.03). We also observed a modest decrease in CRP (-0.27 ng/mL; 95% CI, -0.58 to 0.05), TNF-α (-0.20 ng/mL; 95% CI, -0.54 to 0.15), and IL-6 (-0.53 ng/mL; 95% CI, -1.16 to 0.10) mean plasma concentrations. Subgroup analysis revealed that anthocyanin intake tended to decrease CRP and IL-6 concentrations in overweight or dyslipidemic individuals. Additionally, the intervention duration subgroup analysis showed that anthocyanin supplementation had a stronger effect on plasma IL-6 and TNF-α in participants after 8 to 12 weeks of intervention. In conclusion, our meta-analysis indicated that anthocyanin supplementation can effectively reduce obesity-related inflammatory markers associated with chronic low-grade inflammation.

Meta-Analysis
BACKGROUND
The diagnostic criteria for abdominal obesity are usually waist circumference or waist-to-hip ratio. The magnitude of the risks for cancers of the digestive system and abdominal obesity is unknown. To assess whether abdominal obesity increases the risk of digestive cancer, we conducted a systematic review and meta-analysis of prospective cohort studies in a database.
METHODS
PubMed, Embase, and Web of Science databases were searched from their inception to December 2022. The 9-star Newcastle Ottawa Scale was used to assess study quality. Pooled relative risks and 95% confidence intervals were calculated using fixed or random effect models respectively. The stability of the results was explored by one-by-one exclusion. Subgroup analysis was conducted to explore sources of heterogeneity. Publication bias was evaluated by Begg's and Egger's tests.
RESULTS
A total of 43 cohort studies were included. There were 42 and 31 studies in the meta-analysis of waist circumference and waist-to-hip ratio on digestive system cancer, respectively. The results of the meta-analysis revealed that the greater waist circumference and waist-to-hip ratio were correlated with increased incidence of digestive system cancers: waist circumference: RR 1.48, 95% CI 1.38-1.59, p < 0.001; waist-to-hip ratio: RR 1.33, 95% CI 1.28-1.38, p = 0.001. Subgroup analysis by cancer type showed that higher WC and WHR would increase the prevalence of LC, PC, GC, EC, and CRC. The sensitivity analysis was conducted by a one-by-one elimination method, and the results of the meta-analysis remained stable. It is proved that the results were robust by the trim-and-fill method.
CONCLUSIONS
There was evidence to suggest that abdominal obesity increased the incidence of digestive cancer, it is necessary to take appropriate measures to reduce abdominal obesity. Waist circumference and waist-to-hip ratio may be better predictors of digestive system cancers. However, the association between waist circumference and digestive system cancer was greater, so more attention should be paid to measuring abdominal obesity with waist circumference.

(Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Several studies have reported the prevalence of overweight and obesity in various countries but the global prevalence of nurses with overweight and obesity remains unclear. A consolidation of figures globally can help stakeholders worldwide improve workforce development and healthcare service delivery.
OBJECTIVE
To investigate the global prevalence of overweight and obesity among nurses.
DESIGN
Systematic review with meta-analysis.
SETTING
29 different countries across the WHO-classified geographical region.
PARTICIPANTS
Nurses.
METHODS
Eight electronic databases were searched for articles published from inception to January 2023. Two independent reviewers performed the article screening, methodological appraisal and data extraction. Methodological appraisal was conducted using Newcastle-Ottawa Scale (NOS). Inter-rater agreement was measured using Cohen's Kappa. Meta-analyses were conducted to pool the effect sizes on overweight, obesity and waist circumference using random effects model and adjusted using generalised linear mixed models and Hartung-Knapp method. Logit transformation was employed to stabilise the prevalence variance. Subgroup analyses were performed based on methodological quality and geographical regions. Heterogeneity was assessed using the I statistic.
RESULTS
Among 10,587 studies, 83 studies representing 158,775 nurses across 29 countries were included. Based on BMI, the global prevalence of overweight and obesity were 31.2% (n = 55, 95% CI: 29%-33.5%; p < .01) and 16.3% (n = 76, 95% CI: 13.7%-19.3%, p < .01), respectively. Subgroup analyses indicated that the highest prevalence of overweight was in Eastern Mediterranean (n = 9, 37.2%, 95% CI: 33.1%-41.4%) and that of obesity was in South-East Asia (n = 5, 26.4%, 95% CI: 5.3%-69.9%). NOS classification, NOS scores, sample size and the year of data collected were not significant moderators.
CONCLUSIONS
This review indicated the global prevalence of overweight and obesity among nurses along with the differences between regions. Healthcare organisations and policymakers should appreciate this increased risk and improve working conditions and environments for nurses to better maintain their metabolic health.

Review
In the age of information technology and the additional computational search tools and software available, this systematic review aimed to identify potential therapeutic targets for obesity, evaluated in silico and subsequently validated in vivo. The systematic review was initially guided by the research question "What therapeutic targets have been used in in silico analysis for the treatment of obesity?" and structured based on the acronym PECo (P, problem; E, exposure; Co, context). The systematic review protocol was formulated and registered in PROSPERO (CRD42022353808) in accordance with the Preferred Reporting Items Checklist for Systematic Review and Meta-Analysis Protocols (PRISMA-P), and the PRISMA was followed for the systematic review. The studies were selected according to the eligibility criteria, aligned with PECo, in the following databases: PubMed, ScienceDirect, Scopus, Web of Science, BVS, and EMBASE. The search strategy yielded 1142 articles, from which, based on the evaluation criteria, 12 were included in the systematic review. Only seven these articles allowed the identification of both in silico and in vivo reassessed therapeutic targets. Among these targets, five were exclusively experimental, one was exclusively theoretical, and one of the targets presented an experimental portion and a portion obtained by modeling. The predominant methodology used was molecular docking and the most studied target was Human Pancreatic Lipase (HPL) (n = 4). The lack of methodological details resulted in more than 50% of the papers being categorized with an "unclear risk of bias" across eight out of the eleven evaluated criteria. From the current systematic review, it seems evident that integrating in silico methodologies into studies of potential drug targets for the exploration of new therapeutic agents provides an important tool, given the ongoing challenges in controlling obesity.
