护理模式用于门诊伤口护理中的价值评价

目的评价以患者需求为基础的护理模式用于门诊伤口护理中的价值。方法选取2017年8月—2018年8月在我院门诊进行伤口护理的84例患者,每42例分为试验组和对照组,对照组采取常规伤口护理模式,试验组采取以患者为需求的基础护理模式。经过护理干预后,对比两组患者对疼痛数字量表得分,焦虑自评分以及对护理工作的满意程度。结果试验组患者的疼痛数字量表得分以及焦虑自评分明显低于对照组患者,且两组差异具有统计学意义(P<0.05)。同时试验组患者对护理工作者的满意程度明显高于对照组(P<0.05)。结论以患者需求为基础的护理模式在门诊伤口护理中有较高的实用价值。     

Lower body mass index and higher height are correlated with increased varicocele risk

To evaluate the anthropometric indexes in subjects with varicocele compared to controls and the incidence of varicocele in different body mass index (BMI) groups for the purpose of exploring the association between varicocele and anthropometric indexes. A comprehensive literature search was conducted by using PubMed, MEDLINE, EMBASE databases and Cochrane Library up to February 2019. A systematic review and meta‐analysis was conducted by STATA, and Newcastle–Ottawa Scale was utilised for assessing risk of bias. Ultimately, 13 articles containing seven case–control studies and six cross‐sectional studies with 1,385,630 subjects were involved in our study. Pooled results demonstrated that varicocele patients had a lower BMI (WMD = ?0.77, 95% CI = ?1.03 to ?0.51) and a higher height than nonvaricocele participants, especially in grade 3 varicocele patients. Subgroup analyses showed that normal BMI individuals had a higher risk of varicocele than obese or overweight individuals and a lower risk than underweight individuals. In conclusion, this study indicates that varicocele patients have a lower BMI and a higher height than nonvaricocele participants. Moreover, men with excess bodyweight have a lower incidence of varicocele compared to normal weight or underweight people. That is to say, high BMI and adiposity protect against varicocele and high BMI is associated with a decreased risk of varicocele.
