Meta-Analysis
PURPOSE
Handball (Team Handball) is an intermittent and strenuous contact sport, the successful performance of which depends on frequent body contacts, and the ability to make repeated explosive muscular contractions required for jumping, acceleration, sprinting, turning, changing pace, and throwing a ball. Many studies have investigated the effect of resistance training (RT) in handball players, however with conflicting results. Therefore, our objective was to investigate the impact of RT on maximal strength (isometric and isokinetic strength), the power of both lower and upper limbs, and throwing velocity, in handball players.
METHODS
A comprehensive literature search yielded a pool of 18 studies, which were retained in the systematic review and meta-analysis.
RESULTS
A total of 275 handball players were included. The overall effect size (ES) of RT was 0.996 ([95%CI 0.827-1.165], = 0.0000). At the multivariate meta-regression, the effect of publication year was significant, as well as the effects of country, gender, and level. The impact of RT on isokinetic strength was not significant (ES 0.079 [95%CI -0.060-0.219], = 0.265), whereas the impact of RT on throwing (ES 1.360 [95%CI 0.992-1.728], = 0.000) was significant, as well as the effects of RT on isometric strength (ES 0.398 [95%CI 0.096-0.700], = 0.010), on maximal strength (ES 1.824 [95%CI 1.305-2.343], = 0.000), and on power (ES 0.892 [95%CI 0.656-1.128], = 0.000).
CONCLUSIONS
RT has a significant impact in handball players. Handball coaches could design conditioning protocols and programs based on our results. However, due to a number of shortcomings, including the high, statistically significant heterogeneity among studies and the evidence of publication bias, further high-quality investigations are needed.

AIM
This systematic review and meta-analysis sought to identify return to play (RTP) rates following Achilles tendon rupture and evaluate what measures are used to determine RTP.
DESIGN
A systematic review and meta-analysis were performed. Studies were assessed for risk of bias and grouped based on repeatability of their measure of RTP determination.
DATA SOURCES
PubMed, CINAHL, Web of Science and Scopus databases were searched to identify potentially relevant articles.
ELIGIBILITY CRITERIA FOR SELECTING STUDIES
Studies reporting RTP/sport/sport activity in acute, closed Achilles tendon rupture were included.
RESULTS
108 studies encompassing 6506 patients were included for review. 85 studies included a measure for determining RTP. The rate of RTP in all studies was 80% (95% CI 75% to 85%). Studies with measures describing determination of RTP reported lower rates than studies without metrics described, with rates being significantly different between groups (p<0.001).
CONCLUSIONS
80 per cent of patients returned to play following Achilles tendon rupture; however, the RTP rates are dependent on the quality of the method used to measure RTP. To further understand RTP after Achilles tendon rupture, a standardised, reliable and valid method is required.

Rigidity is one of the cardinal symptoms of Parkinson´s disease (PD). Present in up 89% of cases, it is typically assessed with clinical scales. However, these instruments show limitations due to their subjectivity and poor intra- and inter-rater reliability. To compile all of the objective quantitative methods used to assess rigidity in PD and to study their validity and reliability, a systematic review was conducted using the Web of Science, PubMed, and Scopus databases. Studies from January 1975 to June 2019 were included, all of which were written in English. The Strengthening the Reporting of observational studies in Epidemiology Statement (STROBE) checklist for observational studies was used to assess the methodological rigor of the included studies. Thirty-six studies were included. Rigidity was quantitatively assessed in three ways, using servomotors, inertial sensors, and biomechanical and neurophysiological study of muscles. All methods showed good validity and reliability, good correlation with clinical scales, and were useful for detecting rigidity and studying its evolution. People with PD exhibit higher values in terms of objective muscle stiffness than healthy controls. Rigidity depends on the angular velocity and articular amplitude of the mobilization applied. There are objective, valid, and reliable methods that can be used to quantitatively assess rigidity in people with PD.

Physical training is recommended in several studies and guidelines for the control of type 2 diabetes mellitus (DM2) and its complications. We performed a systematic review about the effects of aerobic training (AT), resistance (RT) or the combination of both (AT/ RT), on glycated hemoglobin (HbA1c) in patients with DM2. Therefore, we included 15 clinical trials with at least 12 weeks duration about training program or recommendations of physical exercise, that evaluated the reduction in HbA1c levels in patients with DM2. Information was obtained on training modality (AT, RT or AT / RT), training parameters, duration and weekly training frequency. The results showed increases in peak or maximal oxygen uptake, exercise tolerance time and muscle strength, depending on the type of training, and a reduction in HbA1c levels. We conclude that exercise training is associated with reductions of HbA1c in patients with DM2. Thus, it can be a complementary tool in the management of these patients.

The burden of pain in newborn infants has been investigated in numerous studies, but little is known about the appropriateness of the use of pain scales according to the specific type of pain or infant condition. This systematic review aimed to evaluate the reporting of neonatal pain scales in randomized trials. A systematic search up to March 2019 was performed in Embase, PubMed, PsycINFO, CINAHL, Cochrane Library, Scopus, and Luxid. Randomized and quasirandomized trials reporting neonatal pain scales were included. Screening of the studies for inclusion, data extraction, and quality assessment was performed independently by 2 researchers. Of 3718 trials found, 352 with 29,137 infants and 22 published pain scales were included. Most studies (92%) concerned procedural pain, where the most frequently used pain scales were the Premature Infant Pain Profile or Premature Infant Pain Profile-Revised (48%), followed by the Neonatal Infant Pain Scale (23%). Although the Neonatal Infant Pain Scale is validated only for acute pain, it was also the second most used scale for ongoing and postoperative pain (21%). Only in a third of the trials, blinding for those performing the pain assessment was described. In 55 studies (16%), pain scales that were used lacked validation for the specific neonatal population or type of pain. Six validated pain scales were used in 90% of all trials, although not always in the correct population or type of pain. Depending on the type of pain and population of infants included in a study, appropriate scales should be selected. The inappropriate use raises serious concerns about research ethics and use of resources.

Comparative Study Meta-Analysis
OBJECTIVE
To present a clear and comprehensive summary of the published data on unicompartmental knee replacement (UKA) or total knee replacement (TKA), comparing domains of outcome that have been shown to be important to patients and clinicians to allow informed decision making.
DESIGN
Systematic review using data from randomised controlled trials, nationwide databases or joint registries, and large cohort studies.
DATA SOURCES
Medline, Embase, Cochrane Controlled Register of Trials (CENTRAL), and Clinical Trials.gov, searched between 1 January 1997 and 31 December 2018.
ELIGIBILITY CRITERIA FOR SELECTING STUDIES
Studies published in the past 20 years, comparing outcomes of primary UKA with TKA in adult patients. Studies were excluded if they involved fewer than 50 participants, or if translation into English was not available.
RESULTS
60 eligible studies were separated into three methodological groups: seven publications from six randomised controlled trials, 17 national joint registries and national database studies, and 36 cohort studies. Results for each domain of outcome varied depending on the level of data, and findings were not always significant. Analysis of the three groups of studies showed significantly shorter hospital stays after UKA than after TKA (-1.20 days (95% confidence interval -1.67 to -0.73), -1.43 (-1.53 to -1.33), and -1.73 (-2.30 to -1.16), respectively). There was no significant difference in pain, based on patient reported outcome measures (PROMs), but significantly better functional PROM scores for UKA than for TKA in both non-trial groups (mean difference -0.58 (-0.88 to -0.27) and -0.32 (-0.48 to -0.15), respectively). Regarding major complications, trials and cohort studies had non-significant results, but mortality after TKA was significantly higher in registry and large database studies (risk ratio 0.27 (0.16 to 0.45)), as were venous thromboembolic events (0.39 (0.27 to 0.57)) and major cardiac events (0.22 (0.06 to 0.86)). Early reoperation for any reason was higher after TKA than after UKA, but revision rates at five years remained higher for UKA in all three study groups (risk ratio 5.95 (1.29 to 27.59), 2.50 (1.77 to 3.54), and 3.13 (1.89 to 5.17), respectively).
CONCLUSIONS
TKA and UKA are both viable options for the treatment of isolated unicompartmental osteoarthritis. By directly comparing the two treatments, this study demonstrates better results for UKA in several outcome domains. However, the risk of revision surgery was lower for TKA. This information should be available to patients as part of the shared decision making process in choosing treatment options.

Review
The present systematic review critically examines the available scientific literature on risk factors for malnutrition in the older population (aged ≥65 y). A systematic search was conducted in MEDLINE, reviewing reference lists from 2000 until March 2015. The 2499 papers identified were subjected to inclusion criteria that evaluated the study quality according to items from validated guidelines. Only papers that provided information on a variable's effect on the development of malnutrition, which requires longitudinal data, were included. A total of 6 longitudinal studies met the inclusion criteria and were included in the systematic review. These studies reported the following significant risk factors for malnutrition: age (OR: 1.038; P = 0.045), frailty in institutionalized persons (β: 0.22; P = 0.036), excessive polypharmacy (β: -0.62; P = 0.001), general health decline including physical function (OR: 1.793; P = 0.008), Parkinson disease (OR: 2.450; P = 0.047), constipation (OR: 2.490; P = 0.015), poor (OR: 3.30; P value not given) or moderate (β: -0.27; P = 0.016) self-reported health status, cognitive decline (OR: 1.844; P = 0.001), dementia (OR: 2.139; P = 0.001), eating dependencies (OR: 2.257; P = 0.001), loss of interest in life (β: -0.58; P = 0.017), poor appetite (β: -1.52; P = 0.000), basal oral dysphagia (OR: 2.72; P = 0.010), signs of impaired efficacy of swallowing (OR: 2.73; P = 0.015), and institutionalization (β: -1.89; P < 0.001). These risk factors for malnutrition in older adults may be considered by health care professionals when developing new integrated assessment instruments to identify older adults' risk of malnutrition and to support the development of preventive and treatment strategies.

Review
The use of probiotics, prebiotics, synbiotics or fermented foods can modulate the gut-brain axis and constitute a potentially therapeutic intervention in psychiatric disorders. This systematic review aims to identify current evidence regarding these interventions in the treatment of patients with DSM/ICD psychiatric diagnoses. Forty-seven articles from 42 studies met the inclusion criteria. Risk of bias was assessed in all included studies. Major depression was the most studied disorder (n = 19 studies). Studies frequently focused on schizophrenia (n = 11) and bipolar disorder (n = 5) and there were limited studies in anorexia nervosa (n = 4), ADHD (n = 3), Tourette (n = 1), insomnia (n = 1), PTSD (n = 1) and generalized anxiety disorder (n = 1). Except in MDD, current evidence does not clarify the role of probiotics and prebiotics in the treatment of mental illness. Several studies point to an improvement in the immune and inflammatory profile (e.g. CRP, IL6), which may be a relevant mechanism of action of the therapeutic response identified in these studies. Future research should consider lifestyle and dietary habits of patients as possible confounders that may influence inter-individual treatment response.

Sports Medicine (Auckland, N.Z.) Dec 2022No previous systematic review has examined the physical health benefits of playing golf or caddying.
BACKGROUND
No previous systematic review has examined the physical health benefits of playing golf or caddying.
OBJECTIVE
To establish the influence of golf participation and physical health in golfers and caddies. More specifically, the review intended to explore the domains of cardiovascular, metabolic and musculoskeletal health, in addition to body composition.
DESIGN
Systematic review.
DATA SOURCES
Electronic literature searches were conducted using PubMed, SPORTDiscus and CINAHL databases in July 2021.
ELIGIBILITY CRITERIA
Experimental (randomised controlled trials, quasi-experiment, pre-post) and non-experimental (case-control, cross-sectional, cohort) articles relating to health and golf, written in English and published in peer-reviewed journals.
RESULTS
Of the 572 articles initially identified, 109 full-text articles were assessed for eligibility with 23 meeting the inclusion criteria. Sixteen articles were rated 'good 'and seven 'fair'. The influence of golf on physical health was mixed, although various articles displayed improvements in balance, systolic blood pressure (SBP) and diastolic blood pressure (DBP), high density lipoprotein-cholesterol (HDL-C) and the ratio of HDL to total cholesterol within golfers. Caddies observed improvements in bone mineral density (BMD), stiffness index and strength. Most of the findings indicate that playing golf or caddying does not influence body mass index (BMI); however, playing golf can positively change other body composition markers such as lean and fat mass.
CONCLUSION
This review demonstrated that golf participation may be an effective method for improving musculoskeletal and cardiovascular health, although mixed findings were observed. Moreover, limited longitudinal evidence suggests that playing golf can positively impact metabolic health and the influence on body composition may be parameter dependent. Additionally, the initial evidence suggests that caddying may improve musculoskeletal health. However, the studies included were limited by their methodological inconsistencies such as: study design, participant demographics and intervention prescription.

Meta-Analysis
The role of low-carbohydrate ketogenic diet (LCKD) as an adjuvant therapy in antitumor treatment is not well established. This systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to investigate the efficacy of LCKD as an adjuvant therapy in antitumor treatment compared to non-ketogenic diet in terms of lipid profile, body weight, fasting glucose level, insulin, and adverse effects; Methods: In this study, databases such as PubMed, Web of Science, Scopus, CINAHL, and Cochrane trials were searched. Only RCTs that involved cancer participants that were assigned to dietary interventions including a LCKD group and a control group (any non-ketogenic dietary intervention) were selected. Three reviewers independently extracted the data, and the meta-analysis was performed using a fixed effects model or random effects model depending on the I value or -value; Results: A total of six articles met the inclusion/exclusion criteria. In the overall analysis, the post-intervention results = standard mean difference, SMD (95% CI) showed total cholesterol (TC) level = 0.25 (-0.17, 0.67), HDL-cholesterol = -0.07 (-0.50, 0.35), LDL-cholesterol = 0.21 (-0.21, 0.63), triglyceride (TG) = 0.09 (-0.33, 0.51), body weight (BW) = -0.34 (-1.33, 0.65), fasting blood glucose (FBG) = -0.40 (-1.23, 0.42) and insulin = 0.11 (-1.33, 1.55). There were three outcomes showing significant results in those in LCKD group: the tumor marker PSA, = 0.03, the achievement of ketosis = 0.010, and the level of satisfaction, = 0.005; Conclusions: There was inadequate evidence to support the beneficial effects of LCKDs on antitumor therapy. More trials comparing LCKD and non-KD with a larger sample size are necessary to give a more conclusive result.
