Scientists Test Deep Brain Stimulation As Potential Anorexia Therapy

A small study in 16 people with severe anorexia has found that implanting stimulation electrodes into the brains of patients could ease their anxiety and help them gain weight. Researchers found that in extreme cases of the eating disorder, the technique - known as deep brain stimulation (DBS) - swiftly helped many of those studied reduce symptoms of either anxiety or depression, and improved their quality of life. A few months later, the improved psychological symptoms began to lead to changes in weight, the researchers said, with the average body mass index (BMI) of the group increasing to 17.3 – a rise of 3.5 points – over the course of the study. Anorexia is a serious eating disorder that affects around 0.5 percent of people worldwide, the majority of them teenage girls. Patients have persistent concerns about their weight, shape and size, and starve themselves to maintain a low weight. Chronic anorexia can be fatal, and in many cases causes severe health problems including weak bones and muscles, sexual problems, infertility, heart problems and seizures. The scientists who led this study, published in The Lancet Psychiatry journal on Friday, said their results suggest deep brain stimulation - which involves implanting electrodes to stimulate brain areas that control dysfunctional behaviors - might alter the brain circuits that drive anorexia. DBS is already used to target brain circuits involved in Parkinson’s disease and tremors - and been shown to be ...

Authors: Golino M, Spera FR, Manfredonia L, De Vita A, Di Franco A, Lamendola P, Villano A, Melita V, Mencarelli E, Lanza GA, Crea F Abstract OBJECTIVE: About one-third of patients undergoing percutaneous coronary interventions (PCIs) for flow-limiting coronary stenosis continue to develop signs of myocardial ischemia (MI) during exercise stress test [EST], despite successful coronary revascularization. Coronary microvascular dysfunction is a likely major cause of the persistence of EST-induced MI in these patients. PATIENTS AND METHODS: We studied 15 patients (14 men, age 67±5 years) fulfilling the foll...

Abstract I tend to become reflective as the end of each year approaches. Thinking about what I managed to achieve during the past 12 months, what I have left undone, and how to try to make the next 12 months better occupies my mind as I drive to and from work or while on my treadmill. The year that is almost over has been a particularly turbulent one in part because of the news about celebrities ending their lives. I certainly enjoyed Anthony Bourdain's books and TV shows and admired his apparent love of the good things in life. Of course, we can never know the truest parts of another's heart, and his suicide in a...

Abstract PROBLEM IDENTIFICATION: Fear of cancer recurrence (FCR) is prevalent among people with cancer; therefore, it is important to determine whether interventions offered to this population are effective in alleviating FCR. This review summarizes randomized, controlled trials in the literature about the effect of psychosocial interventions on FCR in people with cancer. LITERATURE SEARCH: A systematic review of the literature was conducted using PubMed, Web of Science, EMBASE, and Cochrane Library. DATA EVALUATION: Extracted data included cancer type, number of participants, intervention type and durat...

We report an interesting case of hepatic ACC in a young woman with clinical signs of virilization.A-21-year old Sundanese woman visited our endocrine clinic with progressive hirsutism over the face, body, and extremities starting 14 years previously. She had irregular, heavy periods when she was 7 years old. She also experienced pubertal development of her breasts. However, both menstrual cycle and breast development ceased when she was 8 years old. She noticed voice deepening and alopecia. Physical examination showed male-type alopecia and intense hirsutism. Tanner stage was 3 for breast tissue and 5 for pubic hair. There...

Publication date: Available online 19 October 2018Source: Journal of Molecular LiquidsAuthor(s): Xinyi Mei, Zheng Yue, Qiang Ma, Hamza Dunya, Braja K. MandalAbstractThree classes of dicationic ionic liquids (DILs) were synthesized, in which the cationic species [N‑methyl pyrrolidinium (MPy), N‑butyl imidazolium (BIm) or diethylsulfide (DES)] were separated with oligoether moieties. The counter anions are either dicyanamide (DCA) or bis(trifluoromethane sulfonyl)imide (TFSI). The molecular structures of these compounds were identified by FT-IR, 1H NMR and 13C NMR analysis. The DILs were investigated for their potential ...

In this study, a novel image-based finite element modeling algorithm is proposed to acquire the real three-dimensional topography of void defects, including micro X-ray computed tomography scanning, image processing, non-uniform rational B-spline reconstruction and Boolean logic operation. This new algorithm can solve the reconstruction of blurry tomographic slices. Epoxy resin specimens embedded with a low-density expanded polystyrene bead as void defect were fabricated and tested with a digital image correlation system. By using the developed modeling method, the effects of void defect on the ultimate strength, Young's m...
