Recent animal studies found the potential of a collagen peptide derived from skate skin to have anti-obesity effects through the suppression of fat accumulation and regulation of lipid metabolism. However, no studies have yet been performed in humans. Here, this very first human randomized, placebo-controlled, and double-blinded study was designed to investigate the efficacy and tolerability of skate skin collagen peptides (SCP) for the reduction of body fat in overweight adults. Ninety healthy volunteers (17 men) aged 41.2 ± 10.4 years with a mean body mass index of 25.6 ± 1.9 kg/m2 were assigned to the intervention group (IG), which received 2000 mg of SCP per day or to the control group (CG) given the placebo for 12 weeks and 81 (90%) participants completed the study. Changes in body fat were evaluated using dual energy X-ray absorptiometry as a primary efficacy endpoint. After 12 weeks of the trial, the percentage of body fat and body fat mass (kg) in IG were found to be significantly better than those of subjects in CG (−1.2% vs. 2.7%, p = 0.024 and −1.2 kg vs. 0.3 kg, p = 0.025). Application of SCP was well tolerated and no notable adverse effect was reported from both groups. These results suggest the beneficial potential of SCP in the reduction of body fat in overweight adults.

BackgroundCombining the antibiotic azithromycin and hydroxychloroquine induces airway immunomodulatory effects, with the latter also having in vitro antiviral properties. This may improve outcomes in patients hospitalised for COVID-19.MethodsPlacebo-controlled double-blind randomised multicentre trial. Patients ≥18 years, admitted to hospital for≤48 h (not intensive care) with a positive SARS-CoV-2 RT-PCR test, were recruited. The intervention was 500 mg daily azithromycin for 3 days followed by 250 mg daily azithromycin for 12 days combined with 200 mg twice daily hydroxychloroquine for all 15 days. The control group received placebo/placebo. The primary outcome was days alive and discharged from hospital within 14 days (DAOH14).ResultsAfter randomisation of 117 patients, at the first planned interim analysis, the data and safety monitoring board recommended stopping enrolment due to futility, based on pre-specified criteria. Consequently, the trial was terminated on February 1, 2021. A total of 61 patients received the combined intervention and 56 patients received placebo. In the intervention group, patients had a median of 9.0 DAOH14 (IQR, 3–11) versus. 9.0 DAOH14 (IQR, 7–10) in the placebo group (p=0.90). The primary safety outcome, death from all causes on day 30, occurred for 1 patient in the intervention group versus. 2 patients receiving placebo (p=0.52), and readmittance or death within 30 days occurred for 9 patients in the intervention group versus. 6 patients receiving placebo (p=0.57).ConclusionsThe combination of azithromycin and hydroxychloroquine did not improve survival or length of hospitalisation in patients with COVID-19.

Abstract Background: Diabetes mellitus is a common chronic disease. Dyslipidemia and hypertension are two complications that may develop in diabetic patients if hyperglycemia, insulin resistance, and weight gain are not controlled. This study investigated the effects of melatonin supplementation on some cardiovascular disease risk factors and anthropometric indices in patients with type 2 diabetes mellitus (T2DM).Materials and Methods: In this double-blind, randomized, placebo-controlled trial, 50 T2DM patients were randomly allocated to intervention and control groups which received two tablets of either melatonin or placebo (250 mg) once a day for eight weeks. Mean arterial pressure (MAP), pulse pressure (PP), the atherogenic index of plasma (AIP), weight, body mass index (BMI), waist and hip circumference (WC, HC), body shape index (ABSI), abdominal volume index (AVI), body adiposity index (BAI), lipid accumulation product (LAP), conicity index, and waist-to-height ratio (WHR) were evaluated in all the patients pre- and post-intervention.Results: Melatonin supplementation for eight weeks significantly decreased the mean levels of MAP, PP, weight, BMI, WC, HC, BAI, AVI, conicity index, and WHR post-intervention (p<0.05). Also, the median changes of MAP, PP, weight, BMI, WC, HC BAI, AVI, and conicity index were significantly lower in the intervention group compared with the control group (p<0.05). A significant increase (p<0.001) was observed in the mean levels of ABSI in the intervention group. The median changes of ABSI were significantly greater in the intervention group compared with the control group (p<0.001).Conclusions: Consumption of melatonin supplement may be effective in controlling arterial pressure and anthropometric indices (as predictors of obesity) in T2DM patients.Trial registration: This trial was registered in the Iranian Registry of Clinical Trials website at 2019/5/17.

Abstract Background: Posterior canal benign paroxysmal positional vertigo (pc-BPPV) causes physical, functional, and emotional impairment. The treatment of choice is the Epley manoeuvre (EM). The purpose of the study was to compare the impact of the EM and a sham manoeuvre in primary care on self-perceived disability.Method: Randomised, double-blind, sham-controlled clinical trial conducted in primary care with a follow-up of 1 year. Patients aged ≥18 years old diagnosed with pc-BPPV according to the Dix-Hallpike test (DHT) were randomised to an intervention (EM) group or a control (sham manoeuvre) group. The main study covariables were age, sex, history of depression and anxiety, presence of nystagmus in the DHT, patient-perceived disability assessed with the Dizziness Handicap Inventory-screening version (DHI-S). Data were analyzed using bivariate and multivariate mixed Tobit analyses. Results: Overall, 134 patients were studied: 66 in the intervention group and 68 in the control group. Median age was 52 years (interquartile range [IQR], 38.25–68.00 years) and 76.12% of the patients were women. The DHT triggered nystagmus in 40.30% of patients. The median total DHI-S score for the overall sample at baseline was 16 (IQR, 8.00–22.00); 16 [IQR, 10.5–24.0] vs 10 [6.0–14.0] for women vs men (P<0.001) and 16 [IQR, 10.0-24.0] vs 12 [IQR, 8.0–18.0] for patients without nystagmus vs those with nystagmus (P=0.033).Patients treated with the EM experienced a mean reduction of 2.03 points in DHI-S score over the follow-up period compared with patients in the sham group. Conclusion: Pc-BPPV affects the quality of life of primary care patients. A single EM can improve self-perceptions of disability by around 2 points on the DHI-S scale, Trial registration: ClinicalTrials.gov Identifier: NCT01969513. Retrospectively registered.

Abstract Background: Attention-Deficit / Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder, characterized by varying severity in attention deficit and hyperactivity. Studies have shown deficiencies in the serum level of magnesium and vitamin D in ADHD. The aim of this study is to determine the effect of Vitamin D and magnesium supplementation on mental health in children with ADHD.Method: This double‑blind, randomized controlled trial was performed on 66 ADHD children. participants were randomly allocated to receive both Vitamin D (50,000 IU/week) and magnesium (6 mg/kg/day) supplements (n = 33) or placebos (n = 33) for 8 weeks. Strengths and difficulties questionnaire were used to evaluate children’s mental health at baseline and at the end of the study.Results: After 8 weeks of intervention, the serum levels of 25‑hydroxy‑Vitamin D3 and magnesium increased significantly in the intervention group compared with the control group. Also a significant decrease in changes of emotional problems (p=0.001), conduct problems (p=0.002), peer problems (p=0.001), prosocial score (p=0.007), total difficulties (p=0.001), externalizing score (p=0.001), and internalizing score (p=0.001) was seen in intervention group at the end of study.Conclusion: Vitamin D (50,000 IU/week) and magnesium (6 mg/kg/day) co-supplementation during 8-week could improve the behavioral function and mental health in ADHD. Although further well-designed studies with a larger sample size are needed.the IRCT registration: IRCT2016030326886N1.

Abstract Background Hospital Elder Life Program (HELP) provides protocols based on factors for reducing delirium. Due to the lack of geriatric wards and aged care teams in Iran, it seems that some of the original HELP interventions need to be modified through a trial study. Hence, this study was conducted to determine whether the Iranian modified HELP could reduce delirium in geriatric hospitalized patients. Methods This double-blind randomized controlled trial was designed and conducted in a hospital at Kashan University of Medical Sciences in Iran. A total of 195 hospitalized patients aged ≥70 years, were 84 in the Intervention Group (IG) and 111 in the Control Group (CG). After assessing delirium risk factors, participants in the IG group received interventions based on the cognitive, vision/hearing, sleep, mobility, feeding, and hydration protocols by nursing students and the CG group received routine care. Delirium incidence was assessed by the Confusion Assessment Method. Delirium incidence, cognitive and functional abilities, frailty, fall, and length of stay were outcomes. Results The mean age of the patients was 78.53(Standard Deviation = 5.87) years. Delirium incidence was higher in the CG comparing to IG (14.71% vs 3.66%).Significant reduction observed in risk incidence of delirium because of interventions [Odds Ratio:0.124, Confidence Interval: 0.03–0.48]. Conclusion The modified HELP effectively reduced delirium rates in geriatric hospitalized patients.

Complication Of Surgery

AimsSurgical site infection (SSI) is a common complication of surgery with an incidence of about 1% in the United Kingdom. Sutures can lead to the development of a SSI, as micro-organisms can colonize the suture as it is implanted. Triclosan-coated sutures, being antimicrobical, were developed to reduce the rate of SSI. Our aim was to assess whether triclosan-coated sutures cause a reduction in SSIs following arthroplasty of the hip and knee.Patients and MethodsThis two-arm, parallel, double-blinded study involved 2546 patients undergoing elective total hip (THA) and total knee arthroplasty (TKA) at three hospitals. A total of 1323 were quasi-randomized to a standard suture group, and 1223 being quasi-randomized to the triclosan-coated suture group. The primary endpoint was the rate of SSI at 30 days postoperatively.ResultsThe baseline characteristics of age, gender and comorbidities were well matched in the two groups. The rates of superficial SSI were 0.8% in the control group and 0.7% in the intervention group (p = 0.651), and when deep and superficial SSIs were combined the rates were 2.5% and 1.8 (p = 0.266). The length of stay in hospital and the rates of medical complications did not differ significantly between the groups (p = 1.000).ConclusionThis trial provided no evidence that the use of triclosan-coated sutures at THA and TKA leads to a reduction in the rate of SSI.

This study examined the effectiveness of a 6-month intervention to improve the health behaviors and outcomes among women aged 50 years and older. A sample of 580 (intervention n = 295; control n = 285) women was recruited from 26 recreational centers. Only the intervention group participated in the Singapore Physical Activity (PA) and Nutrition Study (SPANS), received health resources (calendar, recipe, and booklets) and motivational support from program ambassadors. The intervention group showed significant improvements in moderate-intensity PA, vigorous-intensity PA, and total PA ( P < .001), increased intake frequency of fruit and vegetables ( P = .049), a reduction in salt and sugary beverage intake ( P ≤ .042), and reductions in systolic blood pressure (BP; −3.68 mm Hg), diastolic BP (−3.54 mm Hg), and percentage body fat (−2.13%; P ≤ .020) when compared with the control group. The SPANS appeared to be efficacious in improving PA and dietary behaviors, reducing BP and percentage body fat among Singaporean women.

Abstract Background: Procedural sedation and analgesia (PSA) is used during colonoscopy to facilitate the procedure and relieve patient’s discomfort. The foremost risk of PSA is respiratory depression. Lidocaine could be a promising additional analgesic in IBD patients to minimise side effects of PSA.Our primary objective was to investigate whether i.v. lidocaine reduces the amount of alfentanil used during PSA in IBD patients. Additionally, we investigated whether lidocaine reduces cardiorespiratory incidents and the amount of propofol required during the procedure.Methods: A randomised, double-blind, placebo controlled study was performed at the endoscopy unit of the Radboud University Medical Centre from November 2016 to December 2018. Seventy-six patients with IBD, ASA 1 or 2, between 18 and 65 years, scheduled for colonoscopy with PSA were included. Patients received lidocaine 1.5 mg kg-1 followed by a continuous infusion of 2 mg kg-1 h-1 (intervention group, n=38) or 0.9% saline in equivalent volumes (control group, n=38) during colonoscopy.Results: There was a reduction in the use of alfentanil (327µg (95%CI=-31-505, p=0.082)), and propofol (39 mg (95%CI=-5-83, p=0.083)) in the lidocaine group compared with the control group. Ten patients (26%) in the control group and 8 patients in the lidocaine group (21%) experienced a period of hypoxia (p=0.788). In both groups, no periods of hypotension were noted.Conclusion: Our investigation has shown a reduction in the use of propofol and alfentanil in patients undergoing colonoscopy with PSA. The differences were not statistically significant. Lidocaine did not reduces the incidence of cardiorespiratory events.Trial registration:EudraCT, 2016-002210-46, registered 19 may 2016,https://www.clinicaltrialsregister.eu/ctr-search/trial/2016-002210-46/resultsISRCTN, ISRCTN47787339, retrospectively registered 6 February 2019, http://www.isrctn.com/ISRCTN47787339

ObjectivePrevious studies have assessed breastfeeding-support programmes. Among these, osteopathic manipulative treatment (OMT) is a frequently used approach, although without strong evidence of efficacy.MethodsA double-blind randomised controlled trial was conducted between July 2013 and March 2016. Breastfed term infants were eligible if one of the following criteria was met: suboptimal breastfeeding behaviour, maternal cracked nipples or maternal pain. The infants were randomly assigned to the intervention or the control group. The intervention consisted of two sessions of early OMT, while in the control group, the manipulations were performed on a doll behind a screen. The primary outcome was the exclusive breastfeeding rate at 1 month, which was assessed in an intention-to-treat analysis. Randomisation was computer generated and only accessible to the osteopath practitioner. The parents, research assistants and paediatricians were masked to group assignment.ResultsOne hundred twenty-eight mother–infant dyads were randomised, with 64 assigned to each group. In each group, five infants were lost to follow-up. In the intervention group, 31 of 59 (53%) of infants were still exclusively breast fed at 1 month vs 39 of 59 (66%) in the control group, (OR 0.55, 95% CI 0.26 to 1.17; p=0.12). After adjustment for suboptimal breastfeeding behaviour, caesarean section, use of supplements and breast shields, the adjusted OR was 0.44 (95% CI 0.17 to 1.11; p=0.08). No adverse effects were reported in either group.ConclusionOMT did not improve exclusive breast feeding at 1 month.Trial registration numberNCT01890668.

Abstract Objectives To evaluate the effectiveness of a novel low-burden behavioral intervention (BI) for weight loss on changes in body weight and cardiometabolic risk factors when implemented with or without meal replacements (MR). Methods Twelve worksites (≥300 employees each) in the Greater Boston area participated in a cluster-randomized controlled trial, with 8 worksites (n = 259 participants) allocated to the intervention group (IG) and 4 worksites (n = 76) to a wait-listed control group (CG). IG participants were further randomized to receive the BI, which emphasizes hunger and craving management via diet composition, for 18 months without or with MR (BI + MR). Weight and cardiometabolic variables were measured at baseline and 6 months for all groups, and also at 12 and 18 months in the IGs. Linear mixed models compared 6-month changes in % weight loss, body mass index (BMI), body fat, and cardiometabolic risk factors for all groups. Similar analyses were conducted for the BI and BI + MR groups at 12 and 18 months. Estimated means and standard deviations were calculated. Statistical models were adjusted for age, sex, baseline measurement, and worksite. Results The study population was 83% female. The Mean ± SD for age and BMI were 47.9 ± 10.4 years and 32.9 ± 5.5 kg/m2, respectively. At 6 months, average weight loss was 9.2 ± 7.2% for BI and 8.3 ± 7.0% for BI + MR. Weight loss was significantly greater in both IGs than the CG (both P < 0.001), but not significant between IGs (P = 0.35). Similar results were observed for BMI and % body fat (both P < 0.01). BI and BI + MR had significant reductions in glucose and triglycerides (P < 0.05) compared to the CG. Changes in total cholesterol and LDL were significantly greater in BI + MR compared to BI alone (P < 0.05). Clinically significant reductions in weight and cardiometabolic risk factors were sustained in the IGs at 12 and 18 months. Conclusions To our knowledge, weight loss in this study was greater than previous scalable worksite-based interventions. Weight loss did not significantly differ between the BI and BI + MR groups, and MR use was associated with additional reductions in total and LDL cholesterol. These results demonstrate the feasibility of novel approaches to achieve clinically impactful weight management in worksite settings. Funding Sources Nutrient Foods LLC.
