The home care mobile app is an effective intervention to support the psychosocial adjustment and self-efficacy of stoma patients after discharge. It ensures the continuity of care and provides nursing guidance for the patients timely.

Background: Pressure ulcers (PUs) are encountered in all types of care settings. The incidence of PUs in the intensive care unit (ICU) is higher for a variety of reasons.The Braden Scale is a widely used tool to assess the risk of PU, but its predictive power is controversial in ICU settings. In this systematic review and meta-analysis, we aimed to evaluate the predictive accuracy of the Braden Scale for measurement of risk of PU in adult ICU patients. Methods: A comprehensive literature search in English databases (PubMed, Cochrane Library, OVID, and Web of Science), Chinese databases (SinoMed, CNKI, and Wanfang), and gray literature was performed. Studies assessing the predictive value of the Braden Scale for risk of PU in adult ICU patients were searched. Quality of the studies was scored with Quality Assessment of Diagnostic Accuracy Studies-2. Country, study design, setting, blinding, and characteristics of included studies were extracted.Results: Eleven full-text articles containing 10 044 patients, comprising 1058 patients with PUs were included. The pooled sensitivity and specificity of the Braden Scale for predicting PU risk in ICU adults were 0.89 (95% CI, 0.87-0.91; I 2 = 94.9%, P = .0000) and 0.28 (95% CI, 0.27-0.29; I 2 = 99.2%, P = .0000), respectively. The pooled DOR was 6.29 (95% CI: 4.09-9.68). The overall weighted AUC was 0.7812 ± 0.0331 (95% CI: 0.7163-0.8461) and the Q* value was 0.7196 ± 0.0283 (95% CI: 0.6641-0.7751). Significant heterogeneity was noted among the included studies.Meta-regression analysis showed that there was no heterogeneity in blinding (P = .074), study design (P = .679), or cut-off value (P = .821). Conclusions:This meta-analysis demonstrated that the Braden Scale had a moderate predictive validity with good sensitivity and low specificity in adult critically ill patients. Further development and modification of this tool or generation of a new tool with higher predictive power is warranted for use in ICU populations.Relevance to clinical practice: The first step in prevention of PU is risk assessment. In this meta-analysis, we aimed to evaluate the predictive power of the Braden Scale for assessing risk of PU in ICU adult patients, which could potentially guide clinical practice.

BackgroundWhether hypothyroidism is an independent risk factor for cardiovascular events is still disputed. We aimed to assess the association between hypothyroidism and risks of cardiovascular events and mortality.MethodsWe searched PubMed and Embase from inception to 29 February 2016. Cohort studies were included with no restriction of hypothyroid states. Priori main outcomes were ischemic heart disease (IHD), cardiac mortality, cardiovascular mortality, and all-cause mortality.ResultsFifty-five cohort studies involving 1,898,314 participants were identified. Patients with hypothyroidism, compared with euthyroidism, experienced higher risks of IHD (relative risk (RR): 1.13; 95% confidence interval (CI): 1.01–1.26), myocardial infarction (MI) (RR: 1.15; 95% CI: 1.05–1.25), cardiac mortality (RR: 1.96; 95% CI: 1.38–2.80), and all-cause mortality (RR: 1.25; 95% CI: 1.13–1.39); subclinical hypothyroidism (SCH; especially with thyrotropin level ≥10 mIU/L) was also associated with higher risks of IHD and cardiac mortality. Moreover, cardiac patients with hypothyroidism, compared with those with euthyroidism, experienced higher risks of cardiac mortality (RR: 2.22; 95% CI: 1.28–3.83) and all-cause mortality (RR: 1.51; 95% CI: 1.26–1.81).ConclusionsHypothyroidism is a risk factor for IHD and cardiac mortality. Hypothyroidism is associated with higher risks of cardiac mortality and all-cause mortality compared with euthyroidism in the general public or in patients with cardiac disease.Electronic supplementary materialThe online version of this article (doi:10.1186/s12916-017-0777-9) contains supplementary material, which is available to authorized users.
