Sleep and recovery in physicians on night call: a longitudinal field study

Background  

It is well known that physicians' night-call duty may cause impaired performance and adverse effects on subjective health, but there is limited knowledge about effects on sleep duration and recovery time. In recent years occupational stress and impaired well-being among anaesthesiologists have been frequently reported for in the scientific literature. Given their main focus on handling patients with life-threatening conditions, when on call, one might expect sleep and recovery to be negatively affected by work, especially in this specialist group. The aim of the present study was to examine whether a 16-hour night-call schedule allowed for sufficient recovery in anaesthesiologists compared with other physician specialists handling less life-threatening conditions, when on call.     

Surgery for ventricular tachycardia in patients undergoing surgical ventricular restoration: The Karolinska approach

This article presents a review on the efficacy of surgical ventricular restoration and direct surgery for ventricular tachycardia in patients with left ventricular aneurysm or dilated ischemic cardiomyopathy. The procedure includes a non-electrophysiologically guided subtotal endocardiectomy and cryoablation in addition to endoventricular patch plasty of the left ventricle. Coronary artery bypass surgery and mitral valve repair are performed concomitantly as needed. In our experience, this procedure yielded a 90% success rate in terms of freedom from spontaneous ventricular tachycardia, with an early mortality rate of 3.8%. A practical guide to the pre- and postoperative management of these patients is provided.

妊高征与眼底视网膜病变的临床探讨

目的 :探讨妊高征患者临床特征与视网膜病变的关系。方法 :观察 2 2 0例妊高征患者的眼底情况。结果 :视网膜病变与水肿关系不密切 ,与平均动脉压、蛋白尿的严重程度、病程及红细胞压积有密切关系 ;有眼底改变者 118例 ,占 5 0 .3%。结论 :眼底镜检查是临床上借以了解视网膜血管的常用方法 ,并可反映妊高征病情的程度 ,为产程处理提供依据     

慢性鼻窦炎患儿家长疾病知识认知度调查

目的了解鼻窦炎患儿家长对儿童鼻窦炎相关知识的认知情况,为进一步加强卫生宣教、预防儿童鼻窦炎提供理论依据。方法对65名鼻窦炎患儿家长进行关于儿童鼻窦炎发病因素、临床表现、并发症以及对儿童生长发育影响等问题的问卷调查。结果调查显示95.4%的家长对儿童鼻窦炎知识缺乏了解,且知识获得途径单一。结论应通过各种途径加强儿童鼻窦炎知识的宣教,积极预防儿童鼻窦炎。     

Bariatric surgery and the gut-brain communication—The state of the art three years later

ObjectiveThis review analyzes the literature concerning gut peptides and bariatric surgery, from 2005 to July 2009. In particular, we are interested in whether, and how, gastrointestinal peptide alterations following surgery interfere with appetite/satiety, and what role they might play in the resolution of comorbidities.Research methods and procedurePubMed/MEDLINE and ISI Web of Knowledge were used to search for human studies concerning gut peptides profiles after any bariatric operation technique.ResultsMost of the studies reviewed had longitudinal design, short follow-up, and low statistical power. The diversity of study results may be partially explained by methodological aspects. Glucagon-like peptide-1, gastric inhibitory peptide, and peptide YY alterations may contribute to the excellent results in glycemic control of diabetics. Results do vary depending on bariatric operation technique; this is particularly evident in the case of ghrelin, which has been much studied in recent years. Ghrelin suppression has been linked to increased satiety, alterations in energy homeostasis, and better glucose metabolism.ConclusionsThere is a lack of long-term data on gastrointestinal hormone profiles after bariatric surgery and the studies have many methodological pitfalls. We still need prospective, long-term, good methodological studies in this area.
