Methodological rigour in preclinical urology: a systematic review reporting research quality over a 14-year period.

OBJECTIVE: To investigate the prevalence and trends of essential study design elements in preclinical urological studies, as well as key factors that may improve methodological rigour, as the demand for methodological rigour in preclinical studies is increasing since research reproducibility and transparency in the medico-scientific field are being questioned. METHODS AND RESULTS: PubMed was searched to include preclinical urological studies published between July 2007 to June 2021. A total of 3768 articles met the inclusion criteria. Data on study design elements and animal models used were collected. Citation density was also examined as a surrogate marker of study influence. We performed an analysis of the prevalence of seven critical study design elements and temporal patterns over 14 years. Randomisation was reported in 50.0%, blinding in 15.0%, sample size estimation in 1.0%, inclusion of both sexes in 6.3%, statistical analysis in 97.1%, housing and husbandry in 47.7%, and inclusion/exclusion criteria in 5.0%. Temporal analysis showed that the implementation of these study design elements has increased, except for inclusion of both sexes and inclusion/exclusion criteria. Reporting study design elements were associated with increased citation density in randomisation and statistical analysis. CONCLUSIONS: The risk of bias is prevalent in 14-year publications describing preclinical urological research, and the quality of methodological rigour is barely related to the citation density of the article. Yet five study design elements (randomisation, blinding, sample size estimation, statistical analysis, and housing and husbandry) proposed by both the National Institutes of Health and Animal Research: Reporting of In Vivo Experiments guidelines have been either well reported or are being well reported over time.

Chronic physical conditions, physical multimorbidity, and quality of life among adults aged ≥ 50 years from six low- and middle-income countries.

PURPOSE: Multimorbidity (i.e., ≥ 2 chronic conditions) poses a challenge for health systems and governments, globally. Several studies have found inverse associations between multimorbidity and quality of life (QoL). However, there is a paucity of studies from low- and middle-income countries (LMICs), especially among the older population, as well as studies examining mediating factors in this association. Thus, the present study aimed to explore the associations, and mediating factors, between multimorbidity and QoL among older adults in LMICs. METHODS: Cross-sectional nationally representative data from the Study on Global Ageing and Adult Health were analyzed. A total of 11 chronic conditions were assessed. QoL was assessed with the 8-item WHO QoL instrument (range 0-100) with higher scores representing better QoL. Multivariable linear regression and mediation analyses were conducted to assess associations. RESULTS: The final sample consisted of 34,129 adults aged ≥ 50 years [mean (SD) age 62.4 (16.0) years; age range 50-114 years; 52.0% females]. Compared to no chronic conditions, 2 (b-coefficient - 5.89; 95% CI - 6.83, - 4.95), 3 (- 8.35; - 9.63, - 7.06), 4 (- 10.87; - 12.37, - 9.36), and ≥ 5 (- 13.48; - 15.91, - 11.06) chronic conditions were significantly associated with lower QoL, dose-dependently. The mediation analysis showed that mobility (47.9%) explained the largest proportion of the association between multimorbidity and QoL, followed by pain/discomfort (43.5%), sleep/energy (35.0%), negative affect (31.9%), cognition (20.2%), self-care (17.0%), and interpersonal activities (12.0%). CONCLUSION: A greater number of chronic conditions was associated with lower QoL dose-dependently among older adults in LMICs. Public health and medical practitioners should aim to address the identified mediators to improve QoL in patients with multimorbidity.

The impact of urinary incontinence on multiple health outcomes: an umbrella review of meta-analysis of observational studies.

BACKGROUND AND AIM: We aimed to capture the breadth of health outcomes that have been associated with the presence of Urinary Incontinence (UI) and systematically assess the quality, strength, and credibility of these associations through an umbrella review and integrated meta-analyses. METHODS: We assessed meta-analyses of observational studies based on random-effect summary effect sizes and their p-values, 95% prediction intervals, heterogeneity, small-study effects, and excess significance. We graded the evidence from convincing (Class I) to weak (Class IV). RESULTS AND DISCUSSION: From 3172 articles returned in search of the literature, 9 systematic reviews were included with a total of 41 outcomes. Overall, 37 out of the 41 outcomes reported nominally significant summary results (p < 0.05), with 22 associations surviving the application of a more stringent p-value (p < 10-6). UI was associated with worse scores than controls in female sexual function (Class II), while it was also associated with a higher prevalence of depression (odds ratio [OR] = 1.815; 95% confidence interval [CI]: 1.551-2.124), and anxiety (OR = 1.498; 95% CI: 1.273-1.762) (Class IV). UI was associated with poorer quality of life (QoL), higher rate of mortality (hazard ratio = 2.392; 95% CI: 2.053-2.787) an increase in falls, frailty, pressure ulcers, diabetes, arthritis, and fecal incontinence (Class IV). CONCLUSIONS: UI is associated with female sexual dysfunction, with highly suggestive evidence. However, the evidence of other adverse outcomes including depression, anxiety, poorer QoL, higher mortality, falls, pressure ulcers, diabetes, arthritis, fecal incontinence, and frailty is only weak. A multidimensional approach should be taken in managing UI in the clinical setting.

Eating disorders and physical multimorbidity in the English general population.

PURPOSE: People with eating disorders may be at increased risk for physical health problems, but there are no data on the relationship between eating disorders and physical multimorbidity (i.e., ≥ 2 physical conditions) and its potential mediators. Thus, we investigated this association in a representative sample of adults from the UK, and quantified the extent to which this can be explained by various psychological and physical conditions, and lifestyle factors. METHODS: Cross-sectional data of the 2007 Adult Psychiatric Morbidity Survey were analyzed. Questions from the five-item SCOFF screening instrument were used to identify possible eating disorder. Respondents were asked about 20 physical health conditions. Multivariable logistic regression and mediation analysis were conducted. RESULTS: Data on 7403 individuals aged ≥ 16 years were analyzed [mean (SD) age 46.3 (18.6) years; 48.6% males]. After adjustment, possible eating disorder was associated with 2.11 (95%CI = 1.67-2.67) times higher odds for physical multimorbidity. Anxiety disorder explained the largest proportion this association (mediated percentage 26.3%), followed by insomnia (21.8%), perceived stress (13.4%), depression (13.1%), obesity (13.0%), and alcohol dependence (4.3%). CONCLUSION: Future longitudinal studies are warranted to understand potential causality and the underlying mechanisms in the association between eating disorder and multimorbidity, and whether addressing the identified potential mediators in people with eating disorders can reduce multimorbidity.

Associations between diabetic retinopathy and modifiable risk factors: An umbrella review of meta-analyses.

AIMS: Several modifiable risk factors have been meta-analysed for diabetic retinopathy (DR), such as physical activity and vitamin D status. To date, these factors have not been systematically aggregated and the credibility of evidence assessed. Therefore, the aim of this umbrella review was to aggregate all modifiable risks of DR and assess the credibility of the evidence. METHODS: An umbrella review of meta-analyses was undertaken. For each meta-analytic association, random-effects effect size, 95% confidence intervals (CIs), heterogeneity, small-study effects, excess significance bias and 95% prediction intervals were calculated. The credibility of significant evidence (p < 0.05) was graded from I to IV, using pre-defined criteria. RESULTS: After initial searches, 13 studies were included covering 34 independent outcomes (total participants = 824,372). Positive associations were found between insulin usage and diabetic macular oedema (RR = 4.5; 95% CI 3.1-6.6), and DR risk (RR = 2.3; 95% CI 1.4-3.9) in people with type 2 diabetes. Vitamin D deficiency was associated with DR risk (OR = 2.8; 95% CI 1.1-7.1), as was obesity (RR = 1.34; 95% CI 1.06-1.68) and sedentary behaviour (RR = 1.22; 95%CI 1.03-1.44). Intensive blood pressure targets (RR = 0.8 95%CI 0.8-1.0), and moderate physical activity (RR = 0.69; 95%CI 0.53-0.91) yielded significant protective associations with DR. CONCLUSIONS: People with type 2 diabetes on insulin have a high risk of macular oedema and DR. Vitamin D deficiency yielded almost three times greater odds of DR, while intensive blood pressure control reduces DR risk by 20% and moderate physical activity by 31%. Healthcare professionals should use this evidence to identify those people most at risk to ensure that proper treatment and healthy lifestyles are recommended.

Associations between diabetic retinopathy, mortality, disease, and mental health: an umbrella review of observational meta-analyses.

BACKGROUND: Diabetic retinopathy is a complication of diabetes affecting the eyes and can lead to blindless if left untreated. Several significant risk factors have been reported for DR, of which several can be classified as some form of disease. Furthermore, several systematic reviews have reported associations between several types of mortality and DR. Numerous meta-analyses have pooled the data on these factors, however, a systematic evaluation of these meta-analytic relationships is lacking. In this study, therefore, we performed an umbrella review of systematic reviews of meta-analyses for mortality, diseases and DR, grading the credibility of evidence. METHODS: A comprehensive database search for observational meta-analyses was conducted from inception until 29/04/2022 against pre-published inclusion criteria. For each meta-analytic outcome, a random-effects meta-analysis was re-conducted, stratifying by study design (and type of DR where possible) of included studies. Several statistical variables, including publication bias, heterogeneity, excess significance bias, and prediction intervals were used to grade the credibility of significant evidence from I to IV, using the recommendations from the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria. RESULTS: Of the 1,834 initial results, 11 systematic reviews with meta-analyses were included covering 16 independent outcomes (total participants = 299,655; median participants per outcome: 7,266; median individual studies per outcome = 5). Overall, 10/16 outcomes (62.5%) yielded significant results, most of which were graded as 'highly suggestive' (Grade II) evidence. DR was associated with all-cause and cardio-vascular mortality, obstructive sleep apnoea, depression eating disorders, and several forms of cognitive impairment. CONCLUSIONS: Results show highly suggestive evidence for associations between health outcomes and/or conditions and DR. Public health professionals and practitioners should note these findings when developing and/or reviewing public health polices.

Physical fitness and disordered eating among adolescents: Results from the EHDLA study.

The aim of this study was to examine the association between a comprehensive spectrum of physical fitness components and disordered eating symptoms in a sample of Spanish adolescents. This cross-sectional study analysed a representative sample of 741 adolescents (55.1% girls) from the Eating Healthy and Daily Life Activities (EHDLA) study (Valle de Ricote, Region of Murcia, Spain). Objective physical fitness (i.e., cardiorespiratory fitness, upper body strength, lower body strength, speed-agility, and flexibility) was assesed by the ALPHA-FIT Test Battery for a young population. Disordered eating symptoms were assessed with the Sick, Control, One, Fat, Food (SCOFF) questionnaire. An incremental inverse association was found in participants with low cardiorespiratory fitness (OR = 2.33; 95% CI: 1.56-3.50), low handgrip strength (OR = 1.99; 95% CI: 1.33-2.97), low lower body strength (OR = 1.91; 95% CI: 1.28-2.86), low speed-agility (OR = 1.75; 95% CI: 1.17-2.62), and low global physical fitness (OR = 2.03; 95% CI: 1.37-3.01) and disordered eating symptoms, compared to participants with a high level of each of these physical fitness components. Our study provides evidence that, in Spanish adolescents, disordered eating symptoms are inversely associated with a comprehensive set of physical fitness components. Hence, it could be relevant to promote physical fitness, e.g., by a multifactorial approach, since it seems to be related to lower disordered eating symptoms in adolescents.

Dietary acrylamide and incident osteoporotic fractures: an 8-year prospective cohort study.

BACKGROUND: Acrylamide, a component of fried foods, has been associated with several negative health outcomes. However, the relationship between dietary acrylamide and osteoporotic fractures has been explored by a few cross-sectional studies. AIMS: To investigate if dietary acrylamide is associated with the onset of fractures in North American participants at high risk/having knee osteoarthritis (OA), over 8 years of follow-up. METHODS: A Cox's regression analysis, adjusted for baseline confounders was run and the data were reported as hazard ratios (HRs) and 95% confidence intervals (CIs). Dietary acrylamide intake was assessed at the baseline using a food frequency questionnaire and categorized in tertiles (T), whilst fractures' history was recorded using self-reported information. RESULTS: Altogether, 4,436 participants were included. Compared to participants with lower acrylamide intake (T1; < 3,313 µg), those with a higher acrylamide intake (T3; > 10,180 µg) reported a significantly higher risk of any fracture (HR = 1.37; 95% CI 1.12-1.68; p for trend = 0.009), forearm (HR = 1.73; 95% CI 1.09-2.77; p for trend = 0.04), spine (HR = 2.21; 95% CI 1.14-4.31; p for trend = 0.04), and hip fracture (HR = 4.09; 95% CI 1.29-12.96; p for trend = 0.046). CONCLUSIONS: Our study is the first to report that high dietary acrylamide may be associated with an increased risk of osteoporotic fractures.

Changes in 25-hydroxyvitamin D levels post-vitamin D supplementation in people of Black and Asian ethnicities and its implications during COVID-19 pandemic: A systematic review.

BACKGROUND: People of Black and Asian ethnicities have a higher infection rate and mortality as a result of COVID-19. It has also been reported that vitamin D deficiency may play a role in this, possibly because of the multi-gene regulatory function of the vitamin D receptor. As a result, increased dietary intake and/or supplementation to attain adequate 25-hydroxyvitamin D (25(OH)D) levels could benefit people in these ethnicities. The present study aimed to review the literature examining the changes in 25(OH)D in different types of vitamin D supplementation from randomised controlled trials in this population. METHODS: This systematic review was conducted using the PRISMA guidelines. Electronic databases were systematically searched using keywords related to vitamin D supplementation in Black and Asian ethnicities. RESULTS: Eight studies were included in the review. All the included studies found that supplementation of vitamin D (D2 and D3 ), regardless of dosage, increased 25(OH)D levels compared to a placebo. All trials in which participants were vitamin D deficient at baseline showed increased 25(OH)D levels to a level considered adequate. Two studies that used food fortification yielded smaller 25(OH)D increases compared to similar studies that used oral supplementation (10.2 vs. 25.5 nmol L-1 , respectively). Furthermore, vitamin D2 supplementation yielded significantly lower 25(OH)D increases than vitamin D3 supplementation. CONCLUSIONS: Oral vitamin D supplementation may be more efficacious in increasing 25(OH)D levels than food fortification of Black and Asian ethnicities, with vitamin D3 supplementation possibly being more efficacious than vitamin D2 . It is recommended that people with darker skin supplement their diet with vitamin D3 through oral tablet modes where possible, with recent literature suggesting a daily intake of 7000-10,000 IU to be potentially protective from unfavourable COVID-19 outcomes. As a result of the paucity of studies, these findings should be treated as exploratory.

The Effects of COVID-19 lockdown on neuropsychiatric symptoms in patients with dementia or mild cognitive impairment: A systematic review and meta-analysis.

The COVID-19 pandemic may have a disproportionate impact on people with dementia/mild cognitive impairment (MCI) due to isolation and loss of services. The aim of this systematic review was to investigate the effects of the COVID-19 lockdown on neuropsychiatric symptoms (NPS) in people living with dementia/MCI. Two authors searched major electronic databases from inception to June 2021 for observational studies investigating COVID-19 and NPS in people with dementia/MCI. Summary estimates of mean differences in NPS scores pre- versus post-COVID-19 were calculated using a random-effects model, weighting cases using inverse variance. Study quality and risk of bias were assessed by the Newcastle-Ottawa Scale. From 2730 citations, 21 studies including 7139 patients (60.0% female, mean age 75.6 ± 7.9 years, 4.0% MCI) with dementia were evaluated in the review. Five studies found no changes in NPS, but in all other studies, an increase in at least one NPS or the pre-pandemic Neuropsychiatric Inventory (NPI) score was found. The most common aggravated NPS were depression, anxiety, agitation, irritability, and apathy during lockdown, but 66.7% of the studies had a high bias. Seven studies including 420 patients (22.1% MCI) yielded enough data to be included in the meta-analysis. The mean follow-up time was 5.9 ± 1.5 weeks. The pooled increase in NPI score before compared to during COVID-19 was 3.85 (95% CI:0.43 to 7.27; P = 0.03; I2  = 82.4%). All studies had high risk of bias. These results were characterized by high heterogeneity, but there was no presence of publication bias. There is an increase in the worsening of NPS in people living with dementia/MCI during lockdown in the COVID pandemic. Future comparative studies are needed to elucidate whether a similar deterioration might occur in people without dementia/MCI.

Ejaculation Disorders in Male Patients with Cancer: A Systematic Review and Meta-Analysis of Prevalence.

PURPOSE: Ejaculatory dysfunction (EjD) and erectile dysfunction after cancer treatment are clinically important complications, but their exact prevalence by various kinds of cancer site and type of treatment is unknown. The aim of this systematic review and meta-analysis was to examine the available evidence and provide pooled estimates for prevalence of EjD and erectile dysfunction in relation to all cancer sites and identify characteristics associated with EjD in cancer patients. MATERIALS AND METHODS: We performed a systematic review and meta-analysis of cross-sectional and case-control studies. We searched 4 electronic databases (Medline®, CINAHL, PsychInfo and Embase®) until July 22, 2020. All retrospective or prospective studies reporting the prevalence of EjD in male patients with cancer were included in this review. A random effects meta-analysis was conducted calculating prevalence proportions with 95% confidence intervals. Prevalence proportions were calculated for the incidences of EjD by cancer site and type of treatment. RESULTS: A total of 64 studies (a total of 10,057 participants) were included for analysis. The most common cancer sites were bladder, colon, testis and rectum. The prevalence rates of EjD after surgical intervention ranged from 14.5% (95% CI 2.2-56.3) in colon cancer to 53.0% (95% CI 23.3-80.7) in bladder cancer. The prevalence rates of erectile dysfunction ranged from 6.8% (95% CI 0.8-39.1) in bladder cancer to 68.7% (95% CI 55.2-79.6) in cancer of the rectum. CONCLUSIONS: In a large study-level meta-analysis, we looked at a high prevalence of EjD and erectile dysfunction at various cancer sites and across different treatment types. Prospective studies of EjD and erectile dysfunction after various kinds of cancer treatments are warranted.

Is loneliness associated with mild cognitive impairment in low- and middle-income countries?

BACKGROUND: Loneliness may be a risk factor for mild cognitive impairment but studies on this topic are scarce, particularly from low- and middle-income countries (LMICs). Therefore, the aim of the present study was to investigate the association between loneliness and mild cognitive impairment (MCI) in six LMICs (China, Ghana, India, Mexico, Russia and South Africa). METHODS: Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. The definition of MCI was based on the National Institute on Ageing-Alzheimer's Association criteria. Multivariable logistic regression analysis and meta-analysis were conducted to assess associations. RESULTS: The final analytical sample consisted of 19,092 and 13,623 individuals aged 50-64 years (middle-aged adults) and ≥65 years (older adults), respectively. Among the middle-aged, overall, loneliness was associated with a non-significant 1.43 (95% confidence interval [CI] = 0.93-2.21) times higher odds for MCI although significant associations were observed in China (OR = 1.51; 95%CI = 1.08-2.09) and South Africa (OR = 3.87; 95%CI = 1.72-8.71). As for older adults, overall, there was a significant association between loneliness and MCI (OR = 1.52; 95%CI = 1.12-2.07). CONCLUSION: In this large representative sample of middle-aged and older adults from multiple LMICs, findings suggest that loneliness is associated with MCI. It may be prudent to consider reducing loneliness in low-economic settings to aid in the prevention of MCI and ultimately dementia.

The association between fear of falling and orthostatic hypotension in older adults.

The aim of this study was to determine the relationship between the fear of falling/the degree of fear of falling (FoF) and orthostatic hypotension (OH) in older adults. This cross-sectional study was conducted with 314 older outpatients. If the total score of the Falls Efficacy Scale-International scale was 16-19, 20-27 and ≥ 28, it was assumed that there was low FoF, moderate FoF and high FoF, respectively. OH was evaluated for the 1st (OH1) and 3rd (OH3) minutes, after transitioning from the supine position to standing. Participants were aged 65-93 years (mean age 74.2 ± 8.5 years) and 193 (61.5%) were female. Among the FoF groups, significant differences were found for age, gender, education, marital status, who the patient lived with, the history of falling and hypertension, Timed Up-Go test score and hemoglobin levels (p < 0.005). The prevalence of OH1 and OH3 was found to be significantly higher in those with an FoF score of 20 and above than those below 20 (p < 0.005). After adjustment for potential confounders, participants who reported a high FoF had higher risk for OH1 and OH3 (OR 2.14, 95% CI 1.14-4.0, p = 0.017; and OR 2.72, 95% CI 1.46-5.09, p = 0.002, respectively), but those with moderate FoF had no increased risk of having OH compared to low FoF (p > 0.05). There is a close relationship between high FoF and OH in older adults. Therefore, when evaluating an older patient with OH, FoF should be evaluated, or FoF should also be questioned in older patients with OH.

Urinary incontinence and quality of life: a systematic review and meta-analysis.

BACKGROUND: Urinary incontinence (UI) and low quality of life (QoL) are two common conditions. Some recent literature proposed that these two entities can be associated. However, no attempt was made to collate this literature. Therefore, the aim of this study was to conduct a systematic review and meta-analysis of existing data to estimate the strength of the association between UI and QoL. METHODS: An electronic search of major databases up to 18th April 2020 was carried out. Meta-analysis of cross-sectional and case-control studies comparing mean values in QoL between patients with UI and controls was performed, reporting random-effects standardized mean differences (SMDs) ± 95% confidence intervals (CIs) as the effect size. Heterogeneity was assessed with the I2. RESULTS: Out of 8279 articles initially screened, 23 were finally included for a total of 24,983 participants, mainly women. The mean age was ≥ 50 years in 12/23 studies. UI was significantly associated with poor QoL as assessed by the short-form 36 (SF-36) total score (n = 6 studies; UI: 473 vs. 2971 controls; SMD = - 0.89; 95% CI - 1.3 to - 0.42; I2 = 93.5) and by the sub-scales of SF-36 and 5/8 of the domains included in the SF-36. Similar results were found using other QoL tools. The risk of bias of the studies included was generally high. CONCLUSIONS: UI is associated with a poor QoL, with a strong level of certainty. This work, however, mainly based on cross-sectional and case-control studies, highlights the necessity of future longitudinal studies for better understanding the importance of UI on QoL.

Prevalence and correlates of body dysmorphic disorder in health club users in the presence vs absence of eating disorder symptomology.

PURPOSE: Body dysmorphic disorder (BDD) has been consistently linked with eating disorders, however studies that stratify associations between BDD in subjects with and without eating disorder symptomology are sparse. It was, therefore, the aim of this study to assess correlates of BDD (including social media use, motivations for exercise, exercise addiction, and sexuality) stratified by eating disorder symptomology. METHODS: Cross-sectional study of 1665 health club users recruited online completed a battery of surveys. BDD prevalence rates were calculated and logistic regression models were created in two sub-samples: indicated or no-indicated eating disorder symptomology. RESULTS: The key findings showed the prevalence of BDD in participants with indicated-eating disorder symptomology was significantly higher than in participants without indicated-eating disorder symptomology, yielding an odds ratio of 12.23. Furthermore, several correlates were associated with BDD only participants with an absence of eating disorder symptomology (gender, BMI, exercise addiction, exercising for mood improvement, attractiveness and tone), with others being significantly associated with BDD in participants in the presence of indicated eating disorders symptomology (exercising for health and enjoyment, relationship status, and ethnicity). CONCLUSIONS: This study provides more evidence of the complex relationship that exists between BDD and eating disorders. Furthermore, it is recommended that practitioners working with BDD subjects should screen for eating disorders due to the high morbidity associated with eating disorders. LEVEL OF EVIDENCE: Level III: case-control analytic study.

A comparative meta-analysis of the prevalence of exercise addiction in adults with and without indicated eating disorders.

BACKGROUND: Exercise addiction is associated with multiple adverse outcomes and can be classified as co-occurring with an eating disorder, or a primary condition with no indication of eating disorders. We conducted a meta-analysis exploring the prevalence of exercise addiction in adults with and without indicated eating disorders. METHODS: A systematic review of major databases and grey literature was undertaken from inception to 30/04/2019. Studies reporting prevalence of exercise addiction with and without indicated eating disorders in adults were identified. A random effect meta-analysis was undertaken, calculating odds ratios for exercise addiction with versus without indicated eating disorders. RESULTS: Nine studies with a total sample of 2140 participants (mean age = 25.06; 70.6% female) were included. Within these, 1732 participants did not show indicated eating disorders (mean age = 26.4; 63.0% female) and 408 had indicated eating disorders (mean age = 23.46; 79.2% female). The odds ratio for exercise addiction in populations with versus without indicated eating disorders was 3.71 (95% CI 2.00-6.89; I2 = 81; p ≤ 0.001). Exercise addiction prevalence in both populations differed according to the measurement instrument used. DISCUSSION: Exercise addiction occurs more than three and a half times as often as a comorbidity to an eating disorder than in people without an indicated eating disorder. The creation of a measurement tool able to identify exercise addiction risk in both populations would benefit researchers and practitioners by easily classifying samples.

GLP-1 receptor agonists and weight loss in schizophrenia - past, present, and future.

PURPOSE OF REVIEW: People with schizophrenia experience three to five times higher prevalence of diabetes and obesity than the general population, contributing to a 20-year reduced lifespan. The impacts of weight gain extend beyond physical health, affecting people's self-esteem, quality of life, and triggering treatment nonadherence, leading to relapse and deteriorations in health. Clinical guidelines recommend patients with antipsychotic-induced weight gain are treated with cognitive behaviour therapy and lifestyle changes; however, effective treatments for obesity in schizophrenia are critically lacking. Glucagon-like peptide-1 receptor agonists (GLP-RAs) have shown large effects in weight loss in the general population; however, effects are less clear in people with schizophrenia. This review aims to assess the clinical trials that have been completed, are in progress, and directions for future trials. RECENT FINDINGS: To date, six clinical trials have been completed, four of which have published their findings. Three further trials are currently in progress. SUMMARY: Results from completed trials suggest that GLP-1RAs decrease weight in people with schizophrenia, however effect sizes are mostly smaller than studies based on the general population. Future trials could focus on dual or triple agonist agents, and/or explore the effects of GLP-1 s at antipsychotic medication commencement, to potentially prevent antipsychotic weight gain.

The role of human involvement and support in digital mental health interventions for people with schizophrenia spectrum disorders: a critical review.

PURPOSE OF REVIEW: Schizophrenia spectrum disorders (SDD) are characterized by a complex array of psychosis symptoms, and typically require ongoing and long-term support, including pharmacological and nonpharmacological management. Digital mental health interventions (DMHIs) have been suggested as a novel therapeutic approach to enable low-cost, scalable improvements in quality of care for adults living with SSD. However, the types and role of human involvement and support within DMHIs is currently unknown. RECENT FINDINGS: Several recent systematic reviews and meta-analyses have investigated the potential efficacy of DMHIs for people with SSD, with scant yet emerging systematic evidence on the effects of human support within DMHIs on mental health outcomes. Further, several recent individual studies examined the efficacy of DMHIs with human support among people with SSD and provided valuable insights into the potential key elements of such support on outcomes relevant to this population. SUMMARY: The current critical review provides the first narrative synthesis of available evidence to guide clinicians and intervention develops in designing DMHIs with adequate human support that may enhance long-term outcomes of people living with SSD.

Emergency Department Presentations for Injuries Following Agency-Notified Child Maltreatment: Results From the Childhood Adversity and Lifetime Morbidity (CALM) Study.

Child maltreatment (CM) is associated with negative health outcomes in adulthood, including deliberate self-harm (DSH), suicidal behaviours, and victimisation. It is unknown if associations extend to emergency department (ED) presentations for non-DSH related injuries. Birth cohort study data was linked to administrative health data, including ED presentations for non DSH related injuries and agency-reported and substantiated notifications for CM. Adjusted analyses (n = 6087) showed that any type of agency-reported notification for CM was significantly associated with increased odds of ED presentation for injuries (aOR = 1.57; 95% CI 1.32-1.87). In moderation analyses, women yielded significantly higher odds of notified and substantiated physical abuse, substantiated emotional abuse, and being subject to more than one type of substantiated abuse than males. ED presentations for injuries could be a proxy for risky behaviours, disguised DSH/suicidal behaviours, or physical abuse. The consistent findings in women may point to victimisation via interpersonal violence.
