Predictors of condom use behaviour among male street labourers in urban Vietnam using a modified Information-Motivation-Behavioral Skills (IMB) model

HIV risk in vulnerable groups such as itinerant male street labourers is often examined via a focus on individual determinants. This study provides a test of a modified Information-Motivation-Behavioral Skills (IMB) model to predict condom use behaviour among male street workers in urban Vietnam. In a cross-sectional survey using a social mapping technique, 450 male street labourers from 13 districts of Hanoi, Vietnam were recruited and interviewed. Collected data were first examined for completeness; structural equation modelling was then employed to test the model fit. Condoms were used inconsistently by many of these men, and usage varied in relation to a number of factors. A modified IMB model had a better fit than the original IMB model in predicting condom use behaviour. This modified model accounted for 49% of the variance, versus 10% by the original version. In the modified model, the influence of psychosocial factors was moderately high, whilst the influence of HIV prevention information, motivation and perceived behavioural skills was moderately low, explaining in part the limited level of condom use behaviour. This study provides insights into social factors that should be taken into account in public health planning to promote safer sexual behaviour among Asian male street labourers.

A conceptual model and detailed framework for stress-related,strain-related,and overuse athletic injury

A multitude of athletic injuries occur when the various tissues that make up the human body experience stresses and strains that exceed their material strength. The precise amount of stress and strain that any given tissue can withstand is determined by the mechanical properties and resultant strength of that particular tissue. These mechanical properties are directly determined by an individual’s physiology and acute regulation of these properties. A number of theoretical frameworks for athletic injury occurrence have been proposed, however, a detailed conceptual framework for injury aetiology that considers the interplay between the physiological and mechanical factors and outlines the causal pathways to tissue damage and injury is needed. This will guide injury research towards a more thorough investigation of causal mechanisms and understanding of risk factors. Further, it is important to take into account the considerable differences in loading patterns which can result in varying injury outcomes such as acute stress-related, strain-related, or overuse injury. Within this article a simplified conceptual model of athletic injury is proposed along with a detailed, evidence-informed, conceptual framework for athletic injury aetiology that focuses on stress-related, strain-related, and overuse injury.

目的研究对心内科实习护士实施WPBL教学模式的效果。方法选取医院心内科实习护士45例展开研究,时间跨度为2018年5月—2018年9月,按模式差异分为对照(常规教学)和观察组(WPBL模式),对比分析两组实习护士学习效果、对心内科理论知识和护理技能掌握程度。结果观察组带教后心内科疾病认知和兴趣(8.11±1.01)分,自主学习能力(7.36±1.11)分,学习效率(7.24±1.21)分,独立思考能力(7.75±1.36)分,护患沟通能力(8.11±1.11)分,临床基础能力(8.44±1.03)分,自身批判性行为(7.25±1.44)分学习效果各项评分明显较对照组高,P<0.05。观察组理论知识掌握度95.5%,护理技能掌握度95.5%,对照组分别为73.9%和69.6%,P<0.05。结论对心内科实习护士实施WPBL教学效果显著,值得推广。     

A new mouse model for the neurodevelopmental ciliopathy Joubert syndrome

Recent recognition of the key role of primary cilia in orchestrating human development and of the dire consequences of their dysfunction on human health has placed this small organelle in the spotlight. While the causal link between mutations in ciliary genes and central nervous system malformations and dysfunction is well established, the mechanisms by which primary cilia dysfunction acts on development and function of the CNS remain partly unknown. The recent article by Bashford and Subramanian in The Journal of Pathology describes a new mouse model for the neurodevelopmental ciliopathy Joubert syndrome, supporting a role for ciliary-mediated Hedgehog signaling on proliferation, survival, and differentiation of cerebellar granule cell progenitors. © 2019 Pathological Society of Great Britain and Ireland.
