多元化联合教学模式在超声引导下疼痛介入治疗中的应用

目的探讨多元化联合教学模式在超声引导下疼痛介入治疗教学中的应用效果。方法选择2018年1月至2020年12月在北京大学第三医院疼痛科进修的30名医师作为研究对象,将其分为对照组与观察组;对照组采用常规教学模式;观察组采用多元化联合教学模式,比较两组医师技能考核成绩、教学质量评分和满意度评分。结果观察组医师技能考核成绩优良率为93.3%,高于对照组的73.3%(P<0.05);观察组医师对基础理论知识掌握、临床思维能力的提高、学习兴趣的激发、疾病诊治能力的提高4个方面的评分均高于对照组(P<0.01)。结论多元化联合教学模式可促进超声引导下疼痛介入治疗技能的提高,有利于提高学员的综合临床能力。

Silver Diamine Fluoride Protocol for Reducing Preventable Dental Hospitalisations in Victorian Children

IntroductionThis study was designed to assess whether a dental caries management protocol combining a single application of 38% silver diamine fluoride (SDF) with comprehensive oral health education will successfully divert high-risk children from dental treatment under dental general anaesthesia (DGA), arrest active caries in primary teeth, and improve parent-reported child oral health–related quality of life (OHRQoL).MethodsChildren aged 2 to 10 years, who attended two public dental agencies in Victoria, Australia, and were unable to tolerate restorative treatments in the clinic setting, elected to participate in either a 38% SDF intervention protocol or, alternatively, referral for DGA. Follow-up examinations were completed at 6 months to assess caries progression, decayed missing filled tooth index, PUFA index (pulpal involvement, ulceration, fistula, abscess), DGA referral rates, and OHRQoL (Early Childhood Oral Health Impact Scale [ECOHIS]).ResultsOf the total sample, 89.5% of children (n = 102) [mean (SD) age, 4.1 (1.0) years] with 401 active carious lesions elected to participate in the 38% SDF protocol; 10.5% (n = 12) of parents opted for referral for treatment under DGA. The proportion of active caries subsequently arrested at follow-up (number of arrested lesions/number of lesions treated) was 0.78 (95% CI, 0.69 to 0.87). There was an 88% reduction in referrals for DGA in eligible children over the 6-month period. The 38% SDF intervention group showed a significant improvement in ECOHIS scores at follow-up (P < .001).DiscussionAdoption of the 38% SDF intervention protocol resulted in a significant reduction in the rate of preventable dental hospitalisations. Most parents opted against referral for DGA. Parent-reported OHRQoL for children improved significantly.     

371名大学生微信朋友圈人格、自我呈现策略与情绪表达的关系

目的 探究大学生微信朋友圈人格、自我呈现策略和情绪表达间的关系。方法 采用社交网络自我呈现策略问卷、艾森克人格问卷简式量表、伯克利情绪表达问卷,对随机抽取的371名大学生进行调查。结果 ⑴外倾型人格总分与真实自我呈现策略总分呈正相关(r=0.170,P=0.001),与正性情绪表达呈正相关(r=0.166,P=0.001),与情绪表达强度呈正相关(r=0.184,P=0.001),真实自我呈现策略与正性情绪表达呈正相关(r=0.239,P=0.001)。⑵真实自我呈现策略在外倾型人格与正性情绪表达的关系中存在部分中介效应。结论 371名大学生的外倾型人格、真实自我呈现策略与正性情绪表达关系密切,真实自我呈现策略在外倾型人格与正性情绪表达的关系中存在部分中介效应。     

冠状动脉慢血流的危险因素及冠状动脉病变特点的研究

目的研究冠状动脉慢血流现象(CSFP)患者的危险因素和分析累及冠状动脉病变的特点。方法回顾性收集本院2019年1月—2021年1月因疑似冠心病行冠状动脉造影术的514例患者,分析患者的临床资料、实验室指标及冠状动脉造影结果等相关资料,按照TIMI血流分级分为慢血流组(n=288)和对照组(n=226),比较两组之间的差异,并通过logistics回归分析探讨CSFP患者的危险因素。结果 (1)两组间在性别、民族、吸烟及饮酒史上存在统计学差异(P<0.05)。(2)CSFP组的血红蛋白、游离三碘甲状原氨酸、血肌酐值、血尿酸水平、空腹血糖水平和左室舒张末期大小均高于对照组(P<0.05);而CSFP组的血小板分布宽度、游离甲状腺素、总胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、载脂蛋白A1和白蛋白水平均低于对照组(P<0.05);(3)CSFP以三支血管病变最多见,为124例(43.0%),而单支血管病变和双支血管病变病例数一样,均为82例(28.5%)。单支血管病变中最多见的是前降支67例(81.7%),其次是右冠状动脉12例(14.6%),左回旋支较少见;(4)多因素logistic回归分析发现:性别、民族、游离甲状腺素、载脂蛋白A1和白蛋白水平是CSFP患者的独立危险因素。结论 (1)男性、少数民族、游离甲状腺素、载脂蛋白A1和白蛋白水平是CSFP的独立危险因素;(2)CSFP更常见于三支冠状动脉病变组,单支冠状动脉病变者更常见于左前降支。     

Overview of Recognition and Prevention of Child Sex Trafficking in the Primary Care Setting: A Primer for Nurse Practitioners

Child sex trafficking (CST) has become a global public health crisis and is a $150 billion criminal enterprise. Nurse practitioners are key in the recognition and prevention of CST in health care settings. Evidence demonstrates that up to 80% of CST victims have had a recent health care encounter. It is the role of the NP in practice to understand risk factors, screen for CST, and educate parents and caregivers on signs of victimization and prevention.     

农村老年人老化期望现状及影响因素研究

目的 了解农村老年人的老化期望现状，分析其影响因素，为针对干预提供参考。 方法 采用一般资料调查表、UCLA孤独感量表简化版、老化期望量表、简版自我感知老化量表对199名农村老年人进行问卷调查。 结果 老化期望总分为32.72±9.18，孤独感得分为15.11±3.82，自我感知老化得分为52.75±2.76；多元线性回归分析显示，性别、婚姻状况、患慢性病种数、独居、孤独感、自我感知老化及经济来源是农村老年人老化期望的影响因素（调整R2=0.612，均P＜0.05）。 结论 农村老年人的老化期望水平较低，女性、孤独、无配偶、患慢性病较多、老化态度消极及低收入人群是关注的重点。
