One patient took Hydroxycut while the other two took Herbalife supplements. Liver biopsies for all patients dem onstrated f indings consistent with drug-induced acute liver injury. To our knowledge, we are the fi rst instit ute to report acute liver injury from both of these two typ es of weight-loss herbal supplements together as a case series. The series emphasizes the importance of taking a cautious approach when consuming herbal supp lements for the purpose of weight loss.展开更多

It is more often multifactorial and more common in elderly. Drugs are considered important causative agents of this disease with different mechanisms. In this paper, we describe a 37-year-old otherwise healthy female presented with sudden onset diffuse abdominal pain and bloody stool. Radiologic, colonoscopic and histopathologic findings were all consistent with ischemic colitis. Her only suspected factor was hydroxycut which she had been taking for a period of 1 mo prior to her presentation. Her condition improved uneventfully after cessation of hydroxycut, bowel rest, intravenous hydration, and antibiotics. This is a first case of ischemic colitis with clear relationship with hydroxycut use (Naranjo score of 7). Our case demonstrates the importance of questioning patients regarding the usage of dietary supplements; especially since many patients consider them safe anddo not disclose their use voluntarily to their physicians. Hydroxycut has to be considered as a potential trigger for otherwise unexplained ischemic colitis.展开更多

We investigated the feasibility and proof of concept of a novel intervention program targeting male supporters of professional sports clubs. Methods: Our intervention is called ViSiT and the target population in this study was overweight male supporters aged 35 - 65 years with a body mass index ≥ 28 kg/m2, recruited through one football and one ice-hockey club. The participants (n = 22) participated in a 12-week lifestyle intervention with a 52-week follow-up. Body fat was assessed using bioelectrical impedance analysis. Results: The retention rate was high with 21 participants completing the 12-week program and 17 attending at least 10 of 12 sessions. Mean (standard deviation) body weight and fat reduction after 12 weeks was 8.2 (4.6) kg and 6.6 (3.6) kg, respectively. At 52 weeks, body weight and fat reduction were maintained at 6.4 (6.7) kg and 4.5 (6.5) kg. Even after 52 weeks follow-up, the participants appreciated most components of the ViSiT program and perceived the ViSiT program to have high impact on most health-related aspects investigated. Conclusions: The ViSiT program demonstrated a successful retention rate and clinically relevant weight reduction in Swedish overweight men. The maintenance of bodyweight reduction and positive experience after 1 year indicate a long-term effect of the ViSiT concept.展开更多

However, the rehabilitation effect of water weight-loss training in stroke patients is currently unclear. Objective: To analyze the effect of water weight loss walking training in stroke patients. Methods: A total of 180 stroke patients admitted to our hospital from January 2019 to December 2021 were selected and randomly divided into two groups. The control group received routine walking training, and the research group performed weight loss walking training in water on this basis. The lower limb motor function, muscle tone grade, daily living ability, gait and balance ability were compared between the two groups before and after treatment. Results: Compared with the control group, the FMA-LE score (Fugl-Meyer motor assessment of Lower Extremity), MBI score (Modified Barthel Index) and BBS score (berg balance scale) of the study group were higher after treatment, and the muscle tone was lower (P Conclusion: Water weight loss walking training can enhance patients’ muscle tension, correct patients’ abnormal gait, improve patients’ balance and walking ability, and contribute to patients’ motor function recovery and self-care ability improvement.展开更多
