Meta-Analysis
Common strategies for reducing body weight rely on limiting energy intake and restricting food choices. However, these strategies have often been proven ineffective in achieving long-term and sustainable weight reduction. More recently, mindful eating as an alternative weight management strategy has gained increasing attention, yet systematic reviews on intuitive or mindful eating published so far present contradictory results. We performed a systematic review and meta-analysis on randomized controlled trials on weight loss programs based on mindful or intuitive eating. We analyzed results using meta-regressions. We included a total of 10 studies and found a significant weight loss effect of mindful/intuitive eating strategies compared with nonintervention controls (-0.348 kg, 95% CI: -0.591 to -0.105, P = 0.005). However, there was no difference compared with conventional diet programs (P = 0.99). Reduction of BMI (-0.137 kg/m , 95% CI: -0.365 to 0.091, P = 0.240) or waist circumference (-0.358 cm, 95% CI: -0.916 to 0.200, P = 0.209) were not statistically significant. Mindful/intuitive eating could be a practical approach to weight control. Limitations of this study include the unbalanced sex, origin, place of residence of the participants, and the short duration of interventions. Future research should aim at investigating long-term effects and include a more heterogeneous study population.

Meta-Analysis
OBJECTIVE
To determine the benefits and harms of pre-admission interventions (prehabilitation) on postoperative outcomes in patients undergoing major elective surgery.
DESIGN
Systematic review and meta-analysis of randomised controlled trials (RCTs) (published or unpublished). We searched Medline, Embase, CENTRAL, DARE, HTA and NHS EED, The Cochrane Library, CINAHL, PsychINFO and ISI Web of Science (June 2020).
SETTING
Secondary care.
PARTICIPANTS
Patients (≥18 years) undergoing major elective surgery (curative or palliative).
INTERVENTIONS
Any intervention administered in the preoperative period with the aim of improving postoperative outcomes.
OUTCOMES AND MEASURES
Primary outcomes were 30-day mortality, hospital length of stay (LoS) and postoperative complications. Secondary outcomes included LoS in intensive care unit or high dependency unit, perioperative morbidity, hospital readmission, postoperative pain, heath-related quality of life, outcomes specific to the intervention, intervention-specific adverse events and resource use.
REVIEW METHODS
Two authors independently extracted data from eligible RCTs and assessed risk of bias and the certainty of evidence using Grading of Recommendations, Assessment, Development and Evaluation. Random-effects meta-analyses were used to pool data across trials.
RESULTS
178 RCTs including eight types of intervention were included. Inspiratory muscle training (IMT), immunonutrition and multimodal interventions reduced hospital LoS (mean difference vs usual care: -1.81 days, 95% CI -2.31 to -1.31; -2.11 days, 95% CI -3.07 to -1.15; -1.67 days, 95% CI -2.31 to -1.03, respectively). Immunonutrition reduced infective complications (risk ratio (RR) 0.64 95% CI 0.40 to 1.01) and IMT, and exercise reduced postoperative pulmonary complications (RR 0.55, 95% CI 0.38 to 0.80, and RR 0.54, 95% CI 0.39 to 0.75, respectively). Smoking cessation interventions reduced wound infections (RR 0.28, 95% CI 0.12 to 0.64).
CONCLUSIONS
Some prehabilitation interventions may reduce postoperative LoS and complications but the quality of the evidence was low.

Meta-Analysis Review
OBJECTIVE
This systematic review analyzed the effects of physical exercise programs in patients with cancer undergoing chemotherapy on chemotherapy-induced peripheral neuropathy (CIPN) prevention.
DATA SOURCES
PubMed, Web of Science, Scopus, and Cochrane Library were searched for relevant studies published before December 2020. Additional references were identified by manual screening of the reference lists.
STUDY SELECTION
Based on the Population, Intervention, Comparator, Outcomes, and Study Designs strategy, randomized controlled trials in which physical exercise was applied before or during chemotherapy to prevent or ameliorate CIPN were included.
DATA EXTRACTION
Two reviewers blinded and independent screened the articles, scored methodologic quality, and extracted data for analysis. The review was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Sensitivity and precision analysis databases was included. Risk of bias assessment and meta-analysis were conducted using the Cochrane tools.
DATA SYNTHESIS
Of 229 potentially relevant studies, 8 randomized controlled trials were included and scored. They comprise a total of 618 patients with cancer. MEDLINE and Scopus databases recorded the highest sensitivity. None of the studies achieved a "low" overall risk of bias. Four studies were included in meta-analysis for quality of life, and a significance standardized mean difference was found between groups from baseline of 14.62; 95% CI, 6.03-3.20, with a large effect size g=0.83; 95% CI, 0.48-1.18) in favor of physical exercise program compared with usual care.
CONCLUSIONS
Physical exercise at the onset of chemotherapy has shown promising effects on the prevention of CIPN, specially improving quality of life.

Meta-Analysis Review
OBJECTIVE
To investigate the effectiveness of walking/running, cycling, or swimming for treating or preventing nonspecific low back pain (LBP).
DESIGN
Intervention systematic review.
LITERATURE SEARCH
Five databases were searched to April 2021.
STUDY SELECTION CRITERIA
Randomized controlled trials evaluating walking/running, cycling, or swimming to treat or prevent LBP were included.
DATA SYNTHESIS
We calculated standardized mean differences (SMDs) and 95% confidence intervals (CIs). Certainty of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
RESULTS
No trials assessed LBP prevention or addressed acute LBP. Nineteen trials (2362 participants) assessed treatment of chronic/recurrent LBP. Low-certainty evidence suggests that walking/running was less effective than alternate interventions in reducing pain in the short term (8 trials; SMD, 0.81; 95% CI: 0.28, 1.34) and medium term (5 trials; SMD, 0.80; 95% CI: 0.10, 1.49). High-certainty evidence suggests that walking/running was less effective than alternate interventions at reducing disability in the short term (8 trials; SMD, 0.22; 95% CI: 0.06, 0.38) and medium term (4 trials; SMD, 0.28; 95% CI: 0.05, 0.51). There was high-certainty evidence of a small effect in favor of walking/running compared to minimal/no intervention for reducing pain in the short term (10 trials; SMD, -0.23; 95% CI: -0.35, -0.10) and medium term (6 trials; SMD, -0.26; 95% CI: -0.40, -0.13) and disability in the short term (7 trials; SMD, -0.19; 95% CI: -0.33, -0.06). Scarcity of trials meant few conclusions could be drawn regarding cycling and swimming.
CONCLUSION
Although less effective than alternate interventions, walking/running was slightly more effective than minimal/no intervention for treating chronic/recurrent LBP. .

Meta-Analysis
Introduction: Identifying the most effective interventions to reverse the metabolic syndrome can be key in the design of clinical strategies to prevent progression to type 2 diabetes mellitus and cardiovascular disease. Objective: To estimate the effect size of the interventions used for the reversal of metabolic syndrome. Materials and methods: We searched in Embase and Medline databases for randomized clinical trials with an outcome defined as the reversal of the metabolic syndrome diagnosis. We classified the interventions in four dimensions: 1) lifestyle (diet and exercise); 2) pharmaceuticals; 3) a combination of both, and 4) control groups, and we conducted a mixed treatment comparison analysis. Results: Additional to the previous meta-analysis published by Dunkley, et al. in 2012, we dentified two other studies. Lifestyle interventions had 2.61 more chances to achieve the reversal of the metabolic syndrome than the control group, with a credible interval between 1.00 and 5.47. Pharmaceutical treatments showed a 3.39 higher chance of reversing the syndrome compared with the control group, but the credible interval was estimated from 0.81 to 9.99. Lifestyle interventions had 1.59 more chance of reversal than the pharmaceutical treatments. Conclusion: Diet and physical activity-based interventions had a higher probability of effectiveness to reverse a metabolic syndrome diagnosis.

Review
BACKGROUND
Surgery is the cornerstone in curative treatment of colorectal cancer. Unfortunately, surgery itself can adversely affect patient health. 'Enhanced Recovery After Surgery' programmes, which include multimodal interventions, have improved patient outcomes substantially. However, these are mainly applied peri- and postoperatively. Multimodal prehabilitation includes multiple preoperative interventions to prepare patients for surgery with the aim of increasing resilience, thereby improving postoperative outcomes.
OBJECTIVES
To determine the effects of multimodal prehabilitation programmes on functional capacity, postoperative complications, and quality of life in adult patients undergoing surgery for colorectal cancer.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase and PsycINFO in January 2021. We also searched trial registries up to March 2021.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) in adult patients with non-metastatic colorectal cancer, scheduled for surgery, comparing multimodal prehabilitation programmes (defined as comprising at least two preoperative interventions) with no prehabilitation. We focused on the following outcomes: functional capacity (i.e. 6-minute walk test, VOpeak, handgrip strength), postoperative outcomes (i.e. complications, mortality, length of hospital stay, emergency department visits, re-admissions), health-related quality of life, compliance, safety of prehabilitation, and return to normal activities.
DATA COLLECTION AND ANALYSIS
Two authors independently selected studies, extracted data, assessed risk of bias and used GRADE to assess the certainty of the evidence. Any disagreements were solved with discussion and consensus. We pooled data to perform meta-analyses, where possible.
MAIN RESULTS
We included three RCTs that enrolled 250 participants with non-metastatic colorectal cancer, scheduled for elective (mainly laparoscopic) surgery. Included trials were conducted in tertiary care centres and recruited patients during periods ranging from 17 months to 45 months. A total of 130 participants enrolled in a preoperative four-week trimodal prehabilitation programme consisting of exercise, nutritional intervention, and anxiety reduction techniques. Outcomes of these participants were compared to those of 120 participants who started an identical but postoperative programme. Postoperatively, prehabilitation may improve functional capacity, determined with the 6-minute walk test at four and eight weeks (mean difference (MD) 26.02, 95% confidence interval (CI) -13.81 to 65.85; 2 studies; n = 131; and MD 26.58, 95% CI -8.88 to 62.04; 2 studies; n = 140); however, the certainty of evidence is low and very low, respectively, due to serious risk of bias, imprecision, and inconsistency. After prehabilitation, the functional capacity before surgery improved, with a clinically relevant mean difference of 24.91 metres (95% CI 11.24 to 38.57; 3 studies; n = 225). The certainty of evidence was moderate due to downgrading for serious risk of bias. Prehabilitation may also result in fewer complications (RR 0.95, 95% CI 0.70 to 1.29; 3 studies; n = 250) and fewer emergency department visits (RR 0.72, 95% CI 0.39 to 1.32; 3 studies; n = 250). The certainty of evidence was low due to downgrading for serious risk of bias and imprecision. On the other hand, prehabilitation may also result in a higher re-admission rate (RR 1.20, 95% CI 0.54 to 2.65; 3 studies; n = 250). The certainty of evidence was again low due to downgrading for risk of bias and imprecision. The effect on VOpeak, handgrip strength, length of hospital stay, mortality rate, health-related quality of life, return to normal activities, safety of the programme, and compliance rate could not be analysed quantitatively due to missing or insufficient data. The included studies did not report a difference between groups for health-related quality of life and length of hospital stay. Data on remaining outcomes were not reported or were reported inadequately in the included studies.
AUTHORS' CONCLUSIONS
Prehabilitation may result in an improved functional capacity, determined with the 6-minute walk test both preoperatively and postoperatively. Complication rates and the number of emergency department visits postoperatively may also diminish due to a prehabilitation programme, while the number of re-admissions may be higher in the prehabilitation group. The certainty of evidence ranges from moderate to very low, due to downgrading for serious risk of bias, imprecision and inconsistency. In addition, only three heterogeneous studies were included in this review. Therefore, the findings of this review should be interpreted with caution. Numerous relevant RCTs are ongoing and will be included in a future update of this review.

Meta-Analysis Review
BACKGROUND
No meta-analysis has analyzed the effect of physical activity level, period of physical activity intervention, and duration of intervention, on perinatal depression. This study was to evaluate the impact of physical activity intensity, dose, period, and duration on perinatal depression.
METHODS
The literature was searched via the PubMed, Embase, Cochrane Library, and Web of Science databases. Weighted mean difference (WMD) or the risk ratio (RR) was used as the effect indicator, and the effect size was represented by the 95 % confidence interval (CI). Subgroup analysis based on the perinatal stage, physical activity intensity, physical activity equivalent, and intervention duration was performed.
RESULTS
Totally, 35 studies including 5084 women were included. Physical activity could reduce the incidence and severity of depression in perinatal women. Among depressed women with prenatal depression, low-intensity physical activity, with metabolic equivalents (METs)-min/week being <450, was associated with lower levels of depression. In the general population, the risk of postpartum depression was lower in the physical activity group when the duration of intervention was ≥12 weeks, being II, III stage, and ≥450 METs-min/week. Both low and moderate-intensity physical activity were beneficial to an improved depression severity among depressed women with postpartum depression, and moderate exercise intervention could decrease the risk of postpartum depression in general pregnant women.
LIMITATIONS
Different types of physical activities may affect the effectiveness of interventions.
CONCLUSION
Our study indicated physical activity specifically targeted at pregnant women could reduce depression risk and severity.

Meta-Analysis
OBJECTIVES
To examine the association between social media use and health risk behaviours in adolescents (defined as those 10-19 years).
DESIGN
Systematic review and meta-analysis.
DATA SOURCES
EMBASE, Medline, APA PsycINFO, SocINDEX, CINAHL, SSRN, SocArXic, PsyArXiv, medRxiv, and Google Scholar (1 January 1997 to 6 June 2022).
METHODS
Health risk behaviours were defined as use of alcohol, drugs, tobacco, electronic nicotine delivery systems, unhealthy dietary behaviour, inadequate physical activity, gambling, and anti-social, sexual risk, and multiple risk behaviours. Included studies reported a social media variable (ie, time spent, frequency of use, exposure to health risk behaviour content, or other social media activities) and one or more relevant outcomes. Screening and risk of bias assessments were completed independently by two reviewers. Synthesis without meta-analysis based on effect direction and random-effects meta-analyses was used. Effect modification was explored using meta-regression and stratification. Certainty of evidence was assessed using GRADE (Grading of Recommendations, Assessment, Development and Evaluations).
RESULTS
Of 17 077 studies screened, 126 were included (73 included in meta-analyses). The final sample included 1 431 534 adolescents (mean age 15.0 years). Synthesis without meta-analysis indicated harmful associations between social media and all health risk behaviours in most included studies, except inadequate physical activity where beneficial associations were reported in 63.6% of studies. Frequent ( infrequent) social media use was associated with increased alcohol consumption (odds ratio 1.48 (95% confidence interval 1.35 to 1.62); n=383 068), drug use (1.28 (1.05 to 1.56); n=117 646), tobacco use (1.85, 1.49 to 2.30; n=424 326), sexual risk behaviours (1.77 (1.48 to 2.12); n=47 280), anti-social behaviour (1.73 (1.44 to 2.06); n=54 993), multiple risk behaviours (1.75 (1.30 to 2.35); n=43 571), and gambling (2.84 (2.04 to 3.97); n=26 537). Exposure to content showcasing health risk behaviours on social media ( no exposure) was associated with increased odds of use of electronic nicotine delivery systems (1.73 (1.34 to 2.23); n=721 322), unhealthy dietary behaviours (2.48 (2.08 to 2.97); n=9892), and alcohol consumption (2.43 (1.25 to 4.71); n=14 731). For alcohol consumption, stronger associations were identified for exposure to user generated content (3.21 (2.37 to 4.33)) versus marketer generated content (2.12 (1.06 to 4.24)). For time spent on social media, use for at least 2 h per day ( <2 h) increased odds of alcohol consumption (2.12 (1.53 to 2.95); n=12 390). GRADE certainty was moderate for unhealthy dietary behaviour, low for alcohol use, and very low for other investigated outcomes.
CONCLUSIONS
Social media use is associated with adverse health risk behaviours in young people, but further high quality research is needed to establish causality, understand effects on health inequalities, and determine which aspects of social media are most harmful.

During pregnancy and the postnatal period many changes occur in a woman's body, both in mental and physical spheres. The birth of a child and a new role-of a mother-can sometimes be associated with numerous negative emotions, uncertainty, fear, anxiety, disgust, depression, or sadness. In the puerperium period, the development of baby blues or postpartum depression may occur. Postpartum depression develops within one month of childbirth and may last up to one year. Depressive disorders that may develop in a young mother affect both her and the newborn's health. That is why it is so important to try to search for factors that could significantly reduce the likelihood of developing depression in this period. The study aims at assessing the relationship between physical activity during pregnancy and puerperium or in the postpartum and the development of postnatal depression. A review of the literature was carried out in the Medline-PubMed database. The search terms were "pregnancy" AND "physical activity AND postpartum depression". The study included only English-language publications published in the period 2000-2018. A total of 216 references were found. After establishing the inclusion and exclusion criteria based on the analysis of titles and abstracts, 173 articles were excluded from the review. A total of 43 publications were read in full. Finally, 16 articles were included in the review. It was shown that regular physical activity during pregnancy, pregnancy, and puerperium, or in the postnatal period itself as compared to inactivity, reduces the risk of developing depression in pregnant women and after the birth of a child. Physical activity can be an essential factor in the prevention of depressive disorders of women in the postnatal period.

Ankle sprains are a common sports-related injury, and female athletes are more likely to sustain this injury than their male counterparts. Previous reviews have evaluated the efficacy of prevention programs in reducing ankle sprains in athletes, but no reviews have specifically focused on female athletes. The objective of this systematic review was to examine the sex-specific effectiveness of neuromuscular training (NMT) programs in reducing the risk of ankle sprains in female athletes. A search of PubMed, Ovid Medline, Embase, and Web of Science databases was performed using the terms: . Studies selected for inclusion were written in English, evaluated female athletes in organized athletics or reported female-specific data for mixed-sex cohorts, included a non-NMT comparison, and used ankle injury rate outcome measures. Seven articles were selected for inclusion, which evaluated a combined 5,187 female basketball, handball, volleyball, soccer, and floorball players. Two studies reported significant differences between NMT participants and controls, concluding the greatest effects were observed in preventing non-contact ankle sprains. The remaining 5 studies, although not statistically significant, revealed an evident trend toward the efficacy of ankle injury prevention with NMT programs. Current available evidence supports the efficacy of NMT in preventing ankle sprains in female athletes. When designing NMT programs, investigators should consider utilizing comprehensive approaches that incorporate strength, balance, plyometric, and agility training as the studies with significant findings created comprehensive NMT programs. Further investigations into sport- and female-specific programs are warranted.
