RESUMO

Systematic review/meta-analysis of cumulative incidences of venous thromboembolic events (VTE) after metabolic and bariatric surgery (MBS). Electronic databases were searched for original studies. Proportional meta-analysis assessed cumulative VTE incidences. (PROSPERO ID:CRD42020184529). A total of 3066 records, and 87 studies were included (N patients = 4,991,683). Pooled in-hospital VTE of mainly laparoscopic studies = 0.15% (95% CI = 0.13-0.18%); pooled cumulative incidence increased to 0.50% (95% CI = 0.33-0.70%); 0.51% (95% CI = 0.38-0.65%); 0.72% (95% CI = 0.13-1.52%); 0.78% (95% CI = 0-3.49%) at 30 days and 3, 6, and 12 months, respectively. Studies using predominantly open approach exhibited higher incidence than laparoscopic studies. Within the first month, 60% of VTE occurred after discharge. North American and earlier studies had higher incidence than non-North American and more recent studies. This study is the first to generate detailed estimates of the incidence and patterns of VTE after MBS over time. The incidence of VTE after MBS is low. Improved estimates and time variations of VTE require longer-term designs, non-aggregated reporting of characteristics, and must consider many factors and the use of data registries. Extended surveillance of VTE after MBS is required.

RESUMO

Walking is the most accessible and common type of physical activity. Exercising at one's self-selected intensity could provide long-term benefits as compared to following prescribed intensities. The aim of this study was to simultaneously examine metabolic, perceptual, spatiotemporal and stability parameters at an absolute 3 km·h-1 speed range around the individual preferred walking speed (PWS). Thirty-four young sedentary adults (18 women) volunteered to walk at seven speeds relative to their PWS in 3-min trials interspaced with 3-min rest intervals. Results indicated a significant main effect of speed on all studied variables. While metabolic, perceptual and spatiotemporal values were sensitive to the smallest change in speed (i.e., 0.5 km·h-1), a significant increase in the rate of carbohydrate oxidation and decrease in %fat oxidation were only observed at speeds above PWS. Results also revealed significantly higher coefficients of variation for stride characteristics at speeds below PWS only. Moreover, analyses of best fit models showed a quadratic relationship between most variables and speed, with the exceptions of metabolic cost of transport, rating of perceived exertion and stride duration that changed exponentially with speed. PWS coincided with optimized mechanical efficiency, fuel oxidation and gait stability. This indicated that walking below PWS decreased both mechanical efficiency and stability of gait, while walking above PWS increased carbohydrate oxidation. Those factors seem to play an important role as determinants of PWS. We suggest that walking at PWS may provide benefits in terms of fat oxidation while optimizing gait stability.

RESUMO

PURPOSE: This is the first study to assess the impact of an online microsurgical testicular sperm extraction (mTESE) masterclass. We: 1) describe the masterclass's scientific content; 2) appraise the participants' acquisition of knowledge; 3) gauge whether the extent of improvement of the participants' knowledge/skills was influenced by demographic/professional attributes; and 4) evaluate the participants' satisfaction. MATERIALS AND METHODS: This masterclass comprised five didactic lectures followed by 4 case discussions. Online surveys assessed the above objectives using a baseline questionnaire including demographics and past mTESE experience/training, a 24-question pre- and post-quiz, and a satisfaction questionnaire. RESULTS: Participants were between 20-70 years old, with 80.37% males, mainly from Asia, Africa, and Europe, from clinical backgrounds (69.3%), and in public practice (64.4%). Half the sample reported no past mTESE training and very low skills, ≈60% wanted considerably more training, and 50% felt that good training was not readily available. Satisfaction was 98% to >99%. Pre- and post-quiz comparisons confirmed remarkable improvements in knowledge/skills, exhibiting five striking characteristics. Improvements were a) Broad i.e., across 19 of the 24 mTESE questions; b) Deep, of magnitude, as pre-/post-quiz scores improved from mean 13.71±4.13 to 17.06±4.73; c) Highly significant, consistently with p-values <0.001; d) Inclusive i.e., all participants enhanced their mTESE knowledge/skills regardless of demographic/professional attributes; and, e) Differential, e.g., non-clinical/clinical participants improved, but the former improved relatively significantly more, those with ≤5-year experience improved significantly more than those with >5-year, those in public practice significantly more than private practice participants, and those with lower self-rating in performing mTESE significantly more than those with higher self-rating. CONCLUSIONS: The masterclass was successful with very high satisfaction levels, and markedly improved mTESE knowledge/skills among the participants. Global Andrology Forum's model can be adopted by organizations with similar goals. Future research needs to evaluate such training to develop a practically non-existent evidence base.

RESUMO

ISSUE ADDRESSED: Due to the nature of their jobs, frontline aged care workers may be a population at risk of poor health and lifestyle habits. Support of their well-being through the workplace is likely to be complex. The objective of this study was to assess the effectiveness of a need-supportive program for changing physical activity and psychological well-being via the motivational processes of behavioural regulations and perceived need satisfaction. METHODS: Frontline aged care workers (n = 25) participated in a single cohort, pre-post pilot trial. The program included a Motivational Interviewing style appointment, education on goal setting and self-management, the use of affect, exertion and self-pacing for regulating physical activity intensity and practical support activities. Outcomes (7-day accelerometery, 6-min walk, K10 and AQoL-8D), and motivational processes (BREQ-3 and PNSE) were measured at baseline, 3 and 9 months, and analysed using linear mixed models for repeated measures. RESULTS: There were significant increases in perceived autonomy at 3 months (Δ .43 ± SE: .20; p = .03) and 6-min walk distance at 9 months (Δ 29.11 m ± SE: 13.75; p = .04), which appeared to be driven by the relative autonomy index (behavioural regulations in exercise questionnaire [BREQ-3]). Amotivation increased at 3 months (Δ .23 ± SE:.12; p = .05); which may have been due to low scores at baseline. No other changes were demonstrated at any timepoint. SO WHAT?: Participants demonstrated positive changes in motivational processes and physical function, however, due to the low levels of participation in the program, the program had a negligible impact at the organisational level. Future researchers and aged care organisations should aim to address factors impacting participation in well-being initiatives.

RESUMO

BACKGROUND: It is important to consider biological sex as a variable that might influence exercise adaptation in order to optimize exercise prescription for men and women. OBJECTIVE: The aim of this study was to quantify the impact of biological sex on maximal oxygen uptake ([Formula: see text]O2max) and performance outcomes after high-intensity interval training (HIIT). METHODS: A systematic search and review was conducted by two independent reviewers up to 8 September 2022 using MEDLINE, SPORTDiscus, and Sports Medicine & Education Index in ProQuest. Trials including healthy adults were included if they presented data for or compared male and female [Formula: see text]O2max or performance outcomes in response to HIIT. Performance outcomes included measures of exercise performance and concurrently measured physiological adaptations. Where appropriate, a random-effects, pre-post meta-analysis was undertaken. Data were sub-grouped for men and women, baseline training level, mean age, intervention type, and intervention length. Heterogeneity was assessed using Chi2, Cochran's Q, and Higgins I2 and sensitivity analyses, where required. Study quality was assessed using the Newcastle-Ottawa Scale and publication bias was assessed through visual inspection of funnel plots. RESULTS: Thirty-three references from 28 trials were included in the review (n = 965; 462 women and 503 men). Meta-analyses included 19 studies for [Formula: see text]O2max, eight for peak power output from [Formula: see text]O2max testing (PPO), and five for threshold power (powerAT). Meta-analyses revealed similar increases in [Formula: see text]O2max in women (g = 0.57; 95% CI 0.44-0.69) and men (g = 0.57; 95% CI 0.42-0.72), and powerAT in women (g = 0.38; 95% CI 0.13-0.64) and men (g = 0.38; 95% CI 0.11-0.64). Raw mean differences for change in [Formula: see text]O2max were Δ 0.32 L·min-1 and 3.50 mL·kg-1·min-1 in men, versus Δ 0.20 L·min-1 and 3.34 mL·kg-1·min-1 for women. No significant sex differences were present for the primary analysis of any outcome. After sub-grouping, significant differences were present for PPO where the effect size was higher for well-trained women (g = 0.37) compared with well-trained men (g = 0.17), and for [Formula: see text]O2max where interventions with a duration of 4 weeks or less had significantly smaller effect sizes compared with those longer than 4 weeks (p < 0.001). Unweighted mean percentage change in [Formula: see text]O2max, PPO, and powerAT across studies was 11.16 ± 7.39%, 11.16 ± 5.99%, and 8.07 ± 6.55% for women, and 10.90 ± 5.75%, 8.22 ± 5.09%, and 7.09 ± 7.17% for men, respectively. Significant heterogeneity was present for both [Formula: see text]O2max and PPO (I2, range: 62.06-78.80%). Sub-grouping by baseline training status and intervention length decreased heterogeneity in most groups. A qualitative synthesis of other outcomes indicated similar improvements in fitness and performance for men and women with some evidence suggesting differences in the mechanisms of adaptation. LIMITATIONS AND RISK OF BIAS: Publication bias is unlikely to have significantly influenced results for [Formula: see text]O2max or powerAT, but the meta-analysis of PPO could have benefitted from additional study data to strengthen results. The overlap in age categories and sensitivity of the analysis limits the accuracy of the results of the sub-grouping by age. CONCLUSIONS: Findings indicated no sex-specific differences for any fitness or performance outcomes. Baseline training status and intervention length accounted for most variability in outcomes.

RESUMO

INTRODUCTION: Postmicturition dribble (PMD) is common in males. Little is known about PMD etiology, but it is either secondary to urethral/prostatic surgery or primary (no previous surgery). Despite PMD's high prevalence, the effectiveness of its treatment modalities remains lacking. OBJECTIVE: To undertake a systematic review of the available treatments for primary PMD in adult males and meta-analysis of their effectiveness. MATERIALS AND METHODS: We searched four electronic databases from inception to 2023 for original articles that evaluated PMD treatments in male adults without previous urethral/prostatic surgery (PROSPERO protocol CRD42023444591). Study quality and risk of bias were evaluated using established tools. We extracted a range of variables including treatment modality used and its effectiveness on PMD volume and patient complaint. Meta-analysis was undertaken where feasible, and where this was not feasible, narrative synthesis was conducted. RESULTS: Out of 335 studies, four were included (four clinical trials, n = 344 patients). Two trials used physical/behavioral therapy (pelvic floor muscle exercises [PFMEs], urethral milking); the other two employed phosphodiesterase (PDE5) inhibitors (tadalafil, Udenafil). All studies were of good quality, but physical/behavioral therapy studies had some risk of bias. As the two physical/behavioral therapy studies used heterogenous outcome measures, narrative synthesis showed PMD volume improvement with PFMEs more than with urethral milking, both modalities were more effective than counseling, and in one study, PFMEs were effective in reducing PMD self-reported complaint than counseling. Meta-analyses of the two PDE5 inhibitors studies showed a large effect size with high heterogeneity for decreased PMD volume favoring PDE5 inhibitors over placebo (g = -0.86, 95% confidence interval [CI] -1.75; 0.02, p = 0.05; I2 = 88%); and a significant improvement equivalent to -1.06 points on the Hallym PMD Questionnaire score with no discernable heterogeneity (95% CI -1.65; -0.47, p = 0.0004; I2 = 0%), favoring PDE5 inhibitors compared to controls. CONCLUSIONS: Physical/behavioral therapy and PDE5 inhibitors are effective primary PMD treatments. PMD management studies in males with no previous urethral/prostatic surgery are very scarce and lack the use of consistent/comparable outcome measures. Further studies addressing these deficiencies would benefit this very thin evidence base.

RESUMO

INTRODUCTION: Definitions and prevalence of weight regain (WR) after bariatric surgery remains inconsistent and their clinical significance unclear. OBJECTIVES: To assess WR five years after sleeve gastrectomy (LSG), employing six definitions; and appraise their association with patient characteristics/clinical outcomes. METHODS: Consecutive patients (N = 589) who underwent LSG were followed up for 5 years. WR prevalence was calculated yearly employing six definitions. Regression analysis assessed associations between WR at 5 years, and patient characteristics (age, sex, preop BMI, number of follow-up visits, number of comorbidities) and remission of comorbidities (type 2 diabetes, hypertension, and dyslipidemia). RESULTS: Sample's mean age and BMI were 34 ± 11.6 years and 43.13 ± 5.77 kg/m2, and 64% were females. Percentage of patients with WR at 2, 3, 4, and 5 years fluctuated between 2.53% and 94.18%, subject to definition, and time point. The definition "Any WR" generated the highest prevalence of WR (86-94%) across all time points. At 5 years, for patient characteristics, preoperative BMI was associated with three definitions (P 0.49 to < 0.001), sex was associated with two (P < 0.026-0.032), and number of comorbidities was associated with one definition (P = 0.01). In terms of comorbidities, only hypertension was associated with WR (one definition, P = 0.025). No other definitions of WR were associated with any of the variables under examination. CONCLUSION: Weight regain is reasonably expected after BMS. WR definitions were of minor clinical significance due to weak associations with limited comorbidities. Dichotomous definitions might offer some guidance while managing individual patients. However, its utility as a comparator metric across patients/procedures requires refinements.

RESUMO

This review aimed to assess the efficacy of workplace physical activity interventions; compare the efficacy of those that were and were not informed by behaviour change theory, and outline the effectiveness of different intervention components. A search was undertaken in Medline, Embase, PsycINFO, Ovid Emcare (previously CINAHL) and SportDiscus. Randomised, non-randomised and cluster-controlled trials with objectively measured physical activity and/or measured or predicted maximal oxygen uptake (VO2max) as outcomes were included in the review (83 papers from 79 trials). Random-effects meta-analyses of mean differences were undertaken. Workplace physical activity programmes demonstrated positive overall intervention effects for daily step counts (814.01 steps/day; CI: 446.36, 1181.67; p < 0.01; i2 = 88%) and measured VO2max (2.53 ml kg-1 min-1; CI: 1.69, 3.36; p < 0.01; i2 = 0%) with no sub-group differences between theory- and non-theory informed interventions. Significant sub-group differences were present for predicted VO2max (p < 0.01), with a positive intervention effect for non-theory informed studies (2.11 ml.kg-1 min-1; CI: 1.20, 3.02; p < 0.01; i2 = 78%) but not theory-informed studies (-0.63 ml kg-1 min-1; CI: -1.55, 0.30; p = 0.18; i2 = 0%). Longer-term follow-ups ranged from 24 weeks to 13 years, with significant positive effects for measured VO2max (2.84 ml kg-1 min-1; CI: 1.41, 4.27; p < 0.01; i2 = 0%). Effective intervention components included the combination of self-monitoring with a goal, and exercise sessions onsite or nearby. The findings of this review were limited by the number and quality of theory-informed studies presenting some outcomes, and confounding issues in complex interventions. Future researchers should consider rigorous testing of outcomes of theory-informed workplace physical activity interventions and incorporate longer follow-ups.

RESUMO

The need to undertake pilot testing and evaluation of novel health promotion programs has become increasingly apparent for the purpose of understanding the true effects of complex interventions and for testing and refining behavioral theories that these interventions are informed by. A mixed-methods process evaluation and feasibility study was undertaken for a need-supportive physical activity program that was piloted in a single-group pre-post study. The piloted program was designed to support participant needs of autonomy, competence, and relatedness through evidence-based and theory-informed behavior change strategies including a motivational interviewing style appointment, education on self-management tools (i.e., pedometers, goal setting, action and coping planning, a customized website for goal setting and self-monitoring), and self-determined methods of regulating physical activity intensity [affect, rating of perceived exertion (RPE), and self-pacing]. The program aimed to positively impact physical activity behavior, psychological well-being, and associated motivational processes. Reach, adoption, fidelity, context, change and performance objectives, and feasibility of the program were evaluated using information from survey respondents from the target population (n = 118) and implementing staff (n = 6); questionnaires from pilot study participants (n = 21); and individual semi-structured interviews with a combination of pilot study participants, non-participants, and implementing staff (n = 19). Process evaluation of the Activity for Well-Being program found that the reach of the program was moderate but adoption was low. The use of self-management tools and self-determined methods of regulating physical activity intensity appeared to be feasible. The website had mixed responses and low engagement. The element of having a support person elicited a strong positive response in the program participant interviews. Involving local implementing staff more directly into the delivery of the intervention could have potentially improved reach, adoption, and feasibility of the program.

RESUMO

OBJECTIVE: Assess the role of exercise intensity on changes in cardiorespiratory fitness (CRF) in patients with cardiac conditions attending exercise-based cardiac rehabilitation. DESIGN: Systematic review with meta-analysis. DATA SOURCES: MEDLINE, Embase, CINAHL, SPORTDiscus, PsycINFO and Web of Science. ELIGIBILITY CRITERIA FOR SELECTION: Studies assessing change in CRF (reported as peak oxygen uptake; V̇O2peak) in patients post myocardial infarction and revascularisation, following exercise-based cardiac rehabilitation. Studies establishing V̇O2peak via symptom-limited exercise test with ventilatory gas analysis and reported intensity of exercise during rehabilitation were included. Studies with mean ejection fraction <40% were excluded. RESULTS: 128 studies including 13 220 patients were included. Interventions were classified as moderate, moderate-to-vigorous or vigorous intensity based on published recommendations. Moderate and moderate-to-vigorous-intensity interventions were associated with a moderate increase in relative V̇O2peak (standardised mean difference±95% CI=0.94±0.30 and 0.93±0.17, respectively), and vigorous-intensity exercise with a large increase (1.10±0.25). Moderate and vigorous-intensity interventions were associated with moderate improvements in absoluteV̇O2peak (0.63±0.34 and 0.93±0.20, respectively), whereas moderate-to-vigorous-intensity interventions elicited a large effect (1.27±0.75). Large heterogeneity among studies was observed for all analyses. Subgroup analyses yielded statistically significant, but inconsistent, improvements in CRF. CONCLUSION: Engagement in exercise-based cardiac rehabilitation was associated with significant improvements in both absolute and relative V̇O2peak. Although exercise of vigorous intensity produced the greatest pooled effect for change in relative V̇O2peak, differences in pooled effects between intensities could not be considered clinically meaningful.

RESUMO

Despite the well-established benefits of regular participation in physical activity, many Australians still fail to maintain sufficient levels. More self-determined types of motivation and more positive affect during activity have been found to be associated with the maintenance of physical activity behaviour over time. Need-supportive approaches to physical activity behaviour change have previously been shown to improve quality of motivation and psychological well-being. This paper outlines the development of a need-supportive, person-centred physical activity program for frontline aged-care workers. The program emphasises the use of self-determined methods of regulating activity intensity (affect, rating of perceived exertion and self-pacing) and is aimed at increasing physical activity behaviour and psychological well-being. The development process was undertaken in six steps using guidance from the Intervention Mapping framework: (i) an in-depth needs assessment (including qualitative interviews where information was gathered from members of the target population); (ii) formation of change objectives; (iii) selecting theory-informed and evidence-based intervention methods and planning their practical application; (iv) producing program components and materials; (v) planning program adoption and implementation, and (vi) planning for evaluation. The program is based in Self-Determination Theory (SDT) and provides tools and elements to support autonomy (the use of a collaboratively developed activity plan and participant choice in activity types), competence (action/coping planning, goal-setting and pedometers), and relatedness (the use of a motivational interviewing-inspired appointment and ongoing support in activity).
