Objective:To explore the effects of intensive nursing intervention on patients with dilated cardiomyopathy and ventricular arrhythmia treated with amiodarone.Methods:Totally 100 patients with dilated cardiomyopathy and ventricular arrhythmia treated with amiodarone who were hospitalized in China-Japan Union Hospital of JiLin University from January 2017 to March 2019 were selected by convenient sampling. Patients hospitalized from January 2017 to February 2018 were divided into the control group, while patients hospitalized from March 2018 to March 2019 were divided into the experimental group. Patients in the control group received routine nursing care, while patients in the experimental group received intensive nursing intervention. The Profile of Mood States-Short Form (POMS-SF) and the World Health Organization Quality of Life (WHOQOL-BREF) were used to evaluate the intervention effects.Results:The POMS-SF scores of the two groups after intervention were lower than those before intervention, and the POMS-SF score of the experimental group was lower than that of the control group, and the differences were statistically significant ( P<0.05) . The WHOQOL-BREF scores of the two groups after intervention were higher than those before intervention, and the WHOQOL-BREF score of the experimental group was higher than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Intensive nursing intervention can mitigate the negative emotion of patients with dilated cardiomyopathy and ventricular arrhythmia treated with amiodarone, and improve their quality of life.

BACKGROUND: Extreme temperature events, including extreme cold, are becoming more frequent worldwide, which might be harmful to pregnant women and cause adverse birth outcomes. We aimed to investigate the association between exposure to low ambient temperature in pregnant women and adverse birth outcomes, such as preterm birth, low birth weight, and stillbirth, and to summarize the evidence herein. METHODS: Relevant studies were searched in PubMed, Cochrane, and Embase electronic databases until November 2021. Studies involving low ambient temperature, preterm birth, birth weight, and stillbirth were included. The guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses were followed to conduct this study risk of bias and methods for data synthesis. RESULTS: A total of 34 studies were included. First, pregnant women exposed to low ambient temperature had an increased risk of preterm birth (risk ratio [RR] 1.08; 95% confidence interval [CI] 1.04-1.13). Subgroup analyses revealed that exposure during late pregnancy was more likely to induce preterm birth. In addition, only pregnant women exposed to <1st percentile of the mean temperature suffered increased risk of preterm birth. Moreover, pregnant women living in medium or hot areas were more prone to have preterm births than those in cold areas when exposed to low ambient temperatures. Asians and Blacks were more susceptible to low ambient temperatures than Caucasians. Second, pregnant women exposed to low ambient temperature had an increased risk of low birth weight (RR 1.07; 95% CI 1.03-1.12). Third, pregnant women had an increased risk of stillbirth while exposed to low ambient temperature during the entire pregnancy (RR 4.63; 95% CI 3.99-5.38). CONCLUSIONS: Exposure to low ambient temperature during pregnancy increases the risk of adverse birth outcomes. Pregnant women should avoid exposure to extremely low ambient temperature (<1st percentile of the mean temperature), especially in their late pregnancy. This study could provide clues for preventing adverse outcomes from meteorological factors. REGISTRATION No. CRD42021259776 at PROSPERO ( https://www.crd.york.ac.uk/PROSPERO/ ).
