硒补充剂对妊娠期糖尿病患者血糖和血脂代谢及妊娠结局的影响分析

目的探讨硒补充剂对妊娠期糖尿病患者血糖、血脂代谢和妊娠结局的影响。方法将2018年7月-2019年6月盘锦市中心医院收治的45例妊娠期糖尿病患者随机分为对照组21例和硒酵母组24例。两组患者均给予健康教育、饮食指导、运动指导等常规治疗,硒酵母组在常规治疗基础上给予硒酵母片治疗。比较两组治疗前后空腹血糖、胰岛素抵抗指数、总胆固醇、甘油三酯、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇水平及妊娠结局。结果治疗后两组空腹血糖和胰岛素抵抗指数均较治疗前下降,且硒酵母组两项指标均低于对照组,差异均具有统计学意义(P<0.05)。治疗后两组孕妇总胆固醇、甘油三酯、低密度脂蛋白胆固醇水平较治疗前下降,且硒酵母组三项指标水平低于对照组,差异均具有统计学意义(P<0.05)。治疗后硒酵母组高密度脂蛋白胆固醇水平高于治疗前,差异具有统计学意义(P<0.05)。对照组治疗前后以及两组治疗后高密度脂蛋白胆固醇水平差异均无统计学意义(P>0.05)。硒酵母组新生儿高胆红素血症发生率和新生儿住院率均低于对照组,差异均具有统计学意义(P<0.05)。两组其他不良妊娠结局差异均无统计学意义(P>0.05)。结论硒补充剂能够进一步改善妊娠期糖尿病患者的血糖和血脂代谢,同时,也能降低新生儿高胆红素血症发生率和住院率,值得推广使用。     

《2020 ACOG实践简报:孕龄≤70 d药物流产(No.225)》解读

药物流产(MA)是早孕期避孕失败的补救措施,主要药物为米非司酮和米索前列醇,二者联合使用,可使早孕期孕妇完全终止妊娠率达到90%。但是,MA导致的患者阴道流血时间长、量多,甚至阴道大流血,而需采取急诊刮宫术治疗等,尚未被彻底解决。如何安全、有效终止早孕期妊娠,保护女性生殖健康是目前国内外该领域的研究重点。美国妇产科医师学学会(ACOG)发布的《2020 ACOG实践简报:孕龄≤70 d药物流产(No.225)》对早孕期孕妇终止妊娠,具有重要指导作用。笔者拟就该简报对MA用于孕龄≤70 d孕妇的临床效果评估,MA用药方案、禁忌证、适应证,MA前咨询和检查,MA疼痛管理,MA后观察、预防性抗菌药物使用、随访管理、避孕措施9个方面基于循证医学推荐进行解读。

Employing computational linguistics techniques to identify limited patient health literacy: Findings from the ECLIPPSE study

ObjectiveTo develop novel, scalable, and valid literacy profiles for identifying limited health literacy patients by harnessing natural language processing.Data SourceWith respect to the linguistic content, we analyzed 283 216 secure messages sent by 6941 diabetes patients to physicians within an integrated system''s electronic portal. Sociodemographic, clinical, and utilization data were obtained via questionnaire and electronic health records.Study DesignRetrospective study used natural language processing and machine learning to generate five unique “Literacy Profiles” by employing various sets of linguistic indices: Flesch‐Kincaid (LP_FK); basic indices of writing complexity, including lexical diversity (LP_LD) and writing quality (LP_WQ); and advanced indices related to syntactic complexity, lexical sophistication, and diversity, modeled from self‐reported (LP_SR), and expert‐rated (LP_Exp) health literacy. We first determined the performance of each literacy profile relative to self‐reported and expert‐rated health literacy to discriminate between high and low health literacy and then assessed Literacy Profiles’ relationships with known correlates of health literacy, such as patient sociodemographics and a range of health‐related outcomes, including ratings of physician communication, medication adherence, diabetes control, comorbidities, and utilization.Principal FindingsLP_SR and LP_Exp performed best in discriminating between high and low self‐reported (C‐statistics: 0.86 and 0.58, respectively) and expert‐rated health literacy (C‐statistics: 0.71 and 0.87, respectively) and were significantly associated with educational attainment, race/ethnicity, Consumer Assessment of Provider and Systems (CAHPS) scores, adherence, glycemia, comorbidities, and emergency department visits.ConclusionsSince health literacy is a potentially remediable explanatory factor in health care disparities, the development of automated health literacy indicators represents a significant accomplishment with broad clinical and population health applications. Health systems could apply literacy profiles to efficiently determine whether quality of care and outcomes vary by patient health literacy; identify at‐risk populations for targeting tailored health communications and self‐management support interventions; and inform clinicians to promote improvements in individual‐level care.     

Validation and psychometric properties of the 8-item Morisky Medication Adherence Scale (MMAS-8) in type 2 diabetes patients in Spain

AimsTo validate a translated and culturally adapted version of the Morisky Medication Adherence Scale for use in Spanish population, and to examine the psychometric properties of this scale in patients with type 2 diabetes mellitus in Spain.DesignThis cross-sectional study was conducted in a single university hospital in Spain. Patients diagnosed with type 2 diabetes mellitus at least 1 year before inclusion, being treated with anti-diabetic medication were included.InterventionWe used the Spanish version of the scale to measure treatment adherence.Principal measurementsthree level categorical scale is broken down into low adherence (score of <6), medium adherence (score of 6 to <8) and high adherence (score of 8). To validate the questionnaire, we measured internal consistency through Cronbach's α, confirmed construct validity through an exploratory principal component analysis and assessed test–retest reliability.Results232 patients met the inclusion criteria. The Cronbach's α coefficient was 0.40 (95% CI 0.28–0.52). The exploratory principal component analysis showed three components. The intraclass correlation coefficient was 0.718 (95% CI 0.564–0.823).Conclusionsthe Spanish version of the Morisky Medication Adherence scale showed low internal consistency, the exploratory factor analysis identified three dimensions, and the test–retest reliability was acceptable, therefore, psychometric properties of MMAS-8 are not suitable for measuring medication adherence in type 2 diabetes mellitus patients from Spain.     

Determinants of information diffusion in online communication on vaccination: The benefits of visual displays

ObjectiveSocial media are an increasingly important source of information on the benefits and risks of vaccinations, but the high prevalence of misinformation provides challenges for informed vaccination decisions. It is therefore important to understand which messages are likely to diffuse online and why, and how relevant aspects—such as scientific facts on vaccination effectiveness—can be made more comprehensible and more likely to be shared. In two studies, we (i) explore which characteristics of messages on flu vaccination facilitate their diffusion in online communication, and (ii) whether visual displays (i.e., icon arrays) facilitate the comprehension and diffusion of scientific effectiveness information.MethodsIn Study 1, 208 participants each rated a random sample of 15 out of 63 messages on comprehensibility, trustworthiness, persuasiveness, familiarity, informativeness, valence, and arousal, and then reported which information they would share with subsequent study participants. In Study 2 (N = 758), we employed the same rating procedure for a selected set of 9 messages and experimentally manipulated how scientific effectiveness information was displayed.ResultsStudy 1 illustrated that scientific effectiveness information was difficult to understand and thus did not diffuse well. Study 2 demonstrated that visual displays improved the understanding of this information, which could, in turn, increase its social impact.ConclusionsThe comprehensibility of scientific information is an important prerequisite for its diffusion. Visual displays can facilitate informed vaccination decisions by rendering important information on vaccination effectiveness more transparent and increasing the willingness to share this information.
