ABSTRACT
INTRODUCTION: Some studies have highlighted the effect of COVID-19 infection on the quality of sleep; however, the data is limited. In this study, we investigated the prevalence of insomnia in patients who recently recovered from the COVID-19 infection to evaluate the prevalence and extent of its impact. METHODS: This longitudinal study was conducted from January 2021 to March 2021. A total of 500 patients admitted to the intensive care unit or isolation unit of COVID-19 were included in the study at the time of their discharge. The pre-COVID-19 sleep quality of the participants was inquired using the Pittsburgh Sleep Quality Index (PSQI). Post-COVID sleep quality was assessed at a 30-day follow-up. Sleep quality was considered poor if the global score was ≥5. Participants that failed to follow up were not included in the study. RESULTS: The mean PSQI score was significantly higher in the post-COVID-19 group compared to the pre-COVID-19 group (6.28 ± 2.11 vs. 3.22 ± 0.80; p-value <0.0001). The percentage of participants with a PSQI score of ≥5 was significantly higher in the post-COVID-19 group compared to the pre-COVID-19 group (45.1% vs. 12.1%; p-value <0.0001). CONCLUSION: Insomnia has a significant prevalence in recovered COVID-19 patients after 30 days of follow-up. Hence, patients need to be counseled to follow up in case they experience poor sleep. To avoid the long-term negative impact on patients experiencing insomnia, timely identification and treatment are important.
ABSTRACT
BACKGROUND: Patients with acute decompensated heart failure are prone to recurrent exacerbation leading to poor quality of life when they do not respond to an optimal medical regimen. Due to the lack of linear positive inotropy response to increasing preload in heart failure patients, increasing preload is associated with poor outcomes. Partial occlusion of either IVC or SVC is a proposed novel treatment that can improve cardiac function or quality of life by altering preload/pressure in heart failure (HF) patients unresponsive to diuretics. METHODS: PubMed, Ovid (MEDLINE), and Cochrane database we searched using the MeSH terms including "Superior vena cava occlusion," "Inferior vena cava occlusion," "Heart failure exacerbation." The inclusion criteria included studies that enrolled patients > 18 years with diagnosed NYHA II-IV HF with reduced ejection fraction (HFrEF) on optimal medical treatment (OMT). RESULTS: The analysis involved two studies with 14 patients; the mean age was 64.4 ± 10 and 100% males. The difference in the mean pulmonary pressures between pre-and-post VCO devices were 1.56 (95% CI 0.66-2.46, p-value = 0.006). There was no heterogeneity among the study of mean pulmonary pressures. With the use of VC occlusion devices, the mean difference in pulmonary artery systolic pressure decreased by 1.70 (95% CI 0.68-2.71, p-value = 0.001) (Fig. 1B). The heterogeneity of mean pressure was minimal 14%. CONCLUSION: In conclusion, VCO can help decrease pulmonary pressure that can indirectly prevent heart failure exacerbations and possibly hospitalization in this cohort of patients.
