Clarifying the Effect of Sleep Deprivation on the Respiratory Muscles

Sleep and critical illness: a review

Critical illness and stays in the Intensive Care Unit (ICU) have significant impact on sleep. Poor sleep is common in this setting, can persist beyond acute critical illness, and is associated with increased morbidity and mortality. In the past 5 years, intensive care clinical practice guidelines have directed more focus on sleep and circadian disruption, spurring new initiatives to study and improve sleep complications in the critically ill. The global SARS-COV-2 (COVID-19) pandemic and dramatic spikes in patients requiring ICU level care also brought augmented levels of sleep disruption, the understanding of which continues to evolve. This review aims to summarize existing literature on sleep and critical illness and briefly discuss future directions in the field.

Independent Predictors of In-Hospital Mortality in Elderly and Non-elderly Adult Patients Undergoing Emergency Admission for Hemorrhoids

Background

The study explored determinants of mortality of admitted emergently patients with the primary diagnosis of hemorrhoids, during the years 2005-2014.

Methods

Demographics, clinical data, and outcomes were obtained from the National Inpatient Sample, 2005-2014, in elderly (65+ years) and non-elderly adult patients (18-64 years) with hemorrhoids who underwent emergency admission. Multivariable logistic regression model with backward elimination was used to identify predictors of mortality.

Results

25 808 adult and 26 978 elderly patients were included. Female patients consisted of 42.5% and 59.3% in adult and elderly, respectively. 42 (.2%) adults died, of which 50% were female and 125 (.5%) elderly patients died, of which 60% were female. Mean (SD) age of the adult patients was 47.8 (11) years and in elderly patients was 78.7 (8) years. 82.2% and 85.7% had internal hemorrhoids in adult and elderly patients, respectively. 9326 (36.1%) adult and 7282 (27%) elderly patients underwent an operation. In the final multivariable logistic regression model for adult patients with operation, delayed operation and invasive diagnostic procedures increased the odds of mortality, whereas in elderly patients, delayed operation and frailty index were the risk factors of mortality. In both adults and elderly with no operation, increased hospital length of stay (HLOS) significantly increased the odds of mortality, and undergoing an invasive diagnostic procedure significantly decreased the odds of mortality.

Conclusion

In all operated patients, increased time to operation and undergoing an invasive diagnostic procedure were the risk factors for mortality. On the other hand, in non-operated emergency hemorrhoids patients, increased age and increased HLOS were the risk factors for mortality while undergoing an invasive diagnostic procedure decreased the odds of mortality.
