Ultrasonic vocalizations and maternal-infant interactions in a rat model of fetal alcohol syndrome

When isolated from their dams and littermates, rat pups emit ultrasonic vocalizations to elicit attention and retrieval from their dams. This study examined the effects of perinatal alcohol exposure on ultrasonic vocalizations and maternal-infant interactions. Alcohol was administered throughout gestation to the dams and during the early postnatal period to the pups. Control groups consisted of a nontreated control and an intubated, pair-fed control. Ultrasonic vocalizations were measured on postnatal day (PD) 5 under varying conditions of isolation. Maternal behaviors were examined on PD2, 4, 6, 8, and 10. Maternal behaviors were not significantly affected by prior alcohol administration to either the dams or the pups. However, ethanol-exposed rat pups vocalized more on PD5 than controls regardless of condition. The heightened vocalization response of the ethanol-exposed pups might be an underlying factor in the persistent effects of perinatal ethanol exposure on social behavior.     

A multi-systemic disease (lupus-like) preceding bronchioloalveolar carcinoma

Summary A patient with a multi-systemic disease (lupus-like) that preceded the onset of a bronchioloalveolar carcinoma is described, and a brief review of the literature is presented. We suggest that this tumor be listed among the neoplasms responsible for multi-systemic diseases with lupus-like characteristics.     

Development of an EQ-5D Value Set for India Using an Extended Design (DEVINE) Study: The Indian 5-Level Version EQ-5D Value Set

ObjectivesThis study aimed to develop the Indian 5-level version EQ-5D (EQ-5D-5L) value set, which is a key input in health technology assessment for resource allocation in healthcare.MethodsA cross-sectional survey using the EuroQol Group’s Valuation Technology was undertaken in a representative sample of 3548 adult respondents, selected from 5 different states of India using a multistage stratified random sampling technique. The participants were interviewed using a computer-assisted personal interviewing technique. This study adopted a novel extended EuroQol Group’s Valuation Technology design that included 18 blocks of 10 composite time trade-off (c-TTO) tasks, comprising 150 unique health states, and 36 blocks of 7 discrete choice experiment (DCE) tasks, comprising 252 DCE pairs. Different models were explored for their predictive performance. Hybrid modeling approach using both c-TTO and DCE data was used to estimate the value set.ResultsA total of 2409 interviews were included in the analysis. The hybrid heteroscedastic model with censoring at ?1 combining c-TTO and DCE data yielded the most consistent results and was used for the generation of the value set. The predicted values for all 3125 health states ranged from ?0.923 to 1. The preference values were most affected by the pain/discomfort dimension.ConclusionsThis is the largest EQ-5D-5L valuation study conducted so far in the world. The Indian EQ-5D-5L value set will promote the effective conduct of health technology assessment studies in India, thereby generating credible evidence for efficient resource use in healthcare.     

群体辨证论治的传承创新与现实意义

目的：纠正对辨证论治的理解偏差,全面精准应用该体系指导临床诊疗实践。方法：通过回顾辨证论治形成与发展的历史脉络,分析人们对辨证论治体系认识局限性原因,找到正确应用的路径。结果：辨证论治从古至今都包含整体与个体二个方面,可现在大家只强调其个体辨证论治的一面,忽略了群体辨证论治的临床应用。结论：完整的辨证论治体系包含个体辨证论治和群体辨证论治二个方面,二者同等重要,不可偏废。随着大数据时代和循证医学的推进,中医群体辨证论治理论具有更加突出的临床现实指导意义。     

Diarrhea Predominant-Irritable Bowel Syndrome (IBS-D): Effects of Different Nutritional Patterns on Intestinal Dysbiosis and Symptoms

Irritable Bowel Syndrome (IBS) is a chronic functional gastrointestinal disorder characterized by abdominal pain associated with defecation or a change in bowel habits. Gut microbiota, which acts as a real organ with well-defined functions, is in a mutualistic relationship with the host, harvesting additional energy and nutrients from the diet and protecting the host from pathogens; specific alterations in its composition seem to play a crucial role in IBS pathophysiology. It is well known that diet can significantly modulate the intestinal microbiota profile but it is less known how different nutritional approach effective in IBS patients, such as the low-FODMAP diet, could be responsible of intestinal microbiota changes, thus influencing the presence of gastrointestinal (GI) symptoms. The aim of this review was to explore the effects of different nutritional protocols (e.g., traditional nutritional advice, low-FODMAP diet, gluten-free diet, etc.) on IBS-D symptoms and on intestinal microbiota variations in both IBS-D patients and healthy subjects. To date, an ideal nutritional protocol does not exist for IBS-D patients but it seems crucial to consider the effect of the different nutritional approaches on the intestinal microbiota composition to better define an efficient strategy to manage this functional disorder.     

低位直肠癌保肛术后低位前切综合征发生的危险因素分析

目的探讨低位直肠癌患者行保肛术后出现低位前切综合征(LARS)的危险因素。方法收集2015年1月-2019年12月在本溪市中心医院行保肛手术治疗的低位直肠癌患者421例,对患者的临床资料进行回顾性分析,并依据患者术后是否发生LARS分为LARS组106例和非LARS组315例、分析LARS发生的危险因素。结果单因素Logistic回归分析显示,年龄,术前放宁、术后恢复时间、坐骨棘间径是LARS发生的危险因素(P<0.05)。多因素Logistic回归分析显示,术前放疗.术后恢复时间、坐骨棘间径是LARS发生的危险因素(P<0.05)。结论对于低位直肠癌行保肛手术治疗患者,术前放疗.术后恢复时间.坐骨棘间径与术后LARS的发生密切相关,对存在上述危险因素的低位直肠癌患者,术前应采取针对性预防措施,或采取其他术式治疗。

术前孤立性CRP升高与体外循环术后并发症的相关性

目的探讨无感染的、术前孤立性C-反应蛋白(CRP)增加,对于体外循环心脏术后的结果,是否有预测性价值。方法分术前孤立性CRP升高(10.5～70.2mg／L)50例(A组)与CRP正常(＜10mg／L)50例对照(B组),B组匹配A组在年龄、性别和疾病种类,两组均进行体外循环心脏手术。结果A组脓毒性并发症(20％)比对照组(2％)多(P＜0.01)。这些病人微生物学阳性仅10％。A组中需要儿茶酚胺支持的占28％,而B组仅12％(P＜0.05)。A组较B组术后需呼吸机支持的时间明显延长(25.2±6.2h比6.6±0.5h)(P＜0.01)、ICU滞留时间也较B组长(4.6±0.8d比2.6±0.3d)(P＜0.05)。结论术前孤立性CRP升高的病人,体外循环术后,发生脓毒性并发症的可能性明显增加。且大多数病例微生物学实验阴性,推测大多数脓毒性并发症是由于全身炎症反应综合征的原因。
