Defining con-founders that affect the reliability of diagnostic tests for coronavirus disease 2019 is vital to breaking the chain of infection. The elderly population is a higher risk group for the emerging virus. However, gender seems to exert a critical role in modifying the infection risk among women owing to hormonal changes. The menopause transition is an exceptional period for older women where the protective and immunomodulatory effects of the estrogen hormone are lost. Accordingly, attention should be given to postmenopausal women since they will have an increased risk compared to their pre-menopausal peers. 相似文献

ObjectiveTo compare levels of postoperative oxycodone use and incisional pain between two randomized groups—an intervention and a control.DesignMixed-methods design; quantitative data achieved via a randomized controlled trial, with qualitative data collected on binder use. The primary variable was oxycodone (in milligrams) required during the first 48 hours after birth, and the secondary variable was incisional pain levels measured on Postoperative Days 1 and 2.SettingAcute-care community hospital in Wheat Ridge, Colorado, and an acute care urban hospital in Denver, Colorado.ParticipantsA total of 220 individuals in the postpartum period after having cesarean birth.Interventions/MeasurementsParticipants were randomized to the intervention group (binder) or the control group (no binder). Data were collected on opioid usage for the first 48 hours. Participants in both groups were asked to rate their incisional pain on Postoperative Day 1 (24 hours after birth) and Postoperative Day 2 (48 hours after birth). Participants in the binder group were also asked to provide feedback on their experience wearing the binder.ResultsA total of 196 participants completed the study. The overall amount of oxycodone taken by individuals in the binder group was lower than that in the control group, but the difference was not statistically significant (p = .10). Pain scores in the binder group were significantly lower on Day 2 compared with the control group (p = .002). The majority of individuals in the binder group provided positive feedback about their experience wearing the binder.ConclusionIndividuals routinely receive medications to assist with pain management postoperatively. Because of growing concerns related to the nation’s opioid addiction crisis, there is interest in using multimodal treatments to achieve adequate pain control for individuals postoperatively. Abdominal binders are a low-cost intervention to assist with pain management and, given the results of this study, seem like a reasonable option to consider. 相似文献

骨质疏松症是常见的骨骼疾病,绝经后女性为骨质疏松症的高危人群。骨折风险评价工具(fracture risk assessment tool,FRAX?)是一款研究、应用广泛的骨折风险评估工具。近年来研究表明,虽然FRAX?尚不完美,但对女性人群的骨折具有合理的预测能力,结合其他骨折危险因素对该工具进行调整、改进的研究也多见报道。设立符合本国国情的FRAX?阈值有助于医生更好地使用该工具和进行临床决策。美国设立了固定的FRAX?阈值,英国则是按年龄分层的阈值。国内对FRAX?的研究尚处于初级阶段,暂无特异的干预阈值,这在一定程度上阻碍了该工具在我国的推广使用。笔者回顾了国内外FRAX?对女性骨质疏松性骨折的预测能力、骨量异常的诊断能力、在合并其他疾病的女性人群中的应用和干预阈值的研究等最新成果,为临床医生了解FRAX?的研究进展、探索针对我国人群干预阈值奠定基础。 相似文献
