Thirty-Day Post-Discharge Outcomes Following COVID-19 Infection

BackgroundThe clinical course of COVID-19 includes multiple disease phases. Data describing post-hospital discharge outcomes may provide insight into disease course. Studies describing post-hospitalization outcomes of adults following COVID-19 infection are limited to electronic medical record review, which may underestimate the incidence of outcomes.ObjectiveTo determine 30-day post-hospitalization outcomes following COVID-19 infection.DesignRetrospective cohort studySettingQuaternary referral hospital and community hospital in New York City.ParticipantsCOVID-19 infected patients discharged alive from the emergency department (ED) or hospital between March 3 and May 15, 2020.MeasurementOutcomes included return to an ED, re-hospitalization, and mortality within 30 days of hospital discharge.ResultsThirty-day follow-up data were successfully collected on 94.6% of eligible patients. Among 1344 patients, 16.5% returned to an ED, 9.8% were re-hospitalized, and 2.4% died. Among patients who returned to the ED, 50.0% (108/216) went to a different hospital from the hospital of the index presentation, and 61.1% (132/216) of those who returned were re-hospitalized. In Cox models adjusted for variables selected using the lasso method, age (HR 1.01 per year [95% CI 1.00–1.02]), diabetes (1.54 [1.06–2.23]), and the need for inpatient dialysis (3.78 [2.23–6.43]) during the index presentation were independently associated with a higher re-hospitalization rate. Older age (HR 1.08 [1.05–1.11]) and Asian race (2.89 [1.27–6.61]) were significantly associated with mortality.ConclusionsAmong patients discharged alive following their index presentation for COVID-19, risk for returning to a hospital within 30 days of discharge was substantial. These patients merit close post-discharge follow-up to optimize outcomes.Supplementary InformationThe online version contains supplementary material available at 10.1007/s11606-021-06924-0.KEY WORDS: COVID-19, mortality, re-admission, discharge     

Reverse LISS plating for intertrochanteric Hip Fractures in elderly patients

Background  

Fractures of the intertrochanteric hip are common and the treatment of unstable fractures generally requires an operative approach. In elderly patients, osteoporosis makes internal fixation problematic and frequently contributes to failed fixation and poor clinical results. We have attempted to apply the Less Invasive Stabilization System (LISS) in reverse position for the repair of intertrochanteric hip fractures in elderly patients with osteoporotic bones. A retrospective review is presented of the cases of 28 elderly patients with stable and unstable fractures of the intertrochanteric hip treated using the reverse LISS.     

Skeletal maturation during thyroxine treatment in children with congenital hypothyroidism

Heyerdahl S, Kase BF, Stake G. Skeletal maturation during thyroxine treatment in children with congenital hypothyroidism. Acta Prediatr 1994;83:618–22. Stockholm. ISSN 0803–5253
The aim of this investigation was to study if bone age development (assessed by the Greulich & Pyle atlas) was related to L-thyroxine treatment in 47 children with congenital hypothyroidism, treated early and according to general recommendations. In spite of frequent delay in skeletal maturation at diagnosis, the delay in mean bone age at a mean chronological age of 1.5 years was slight (0.5 months), and 30% of the variation in bone age SD score (SDS) at 1.5 years was accounted for by the dose of L-thyroxine and serum thyroxine during the first year. The children with a bone age within ± 1 SDS had a prescribed mean dose of L-thyroxine per kg body weight from 3 to 12 months of age of 5.4 ± 1.7 pg/kg/day, and their mean serum thyroxine concentration during the first year was 175 ± 29 nmol/l. We conclude that bone age at 1.5 years of age was positively correlated with the dose of L-thyroxine and the serum thyroxine concentration during the first year. This supports the general use of bone age assessments as a complement to other treatment variables in the follow-up of children with congenital hypothyroidism.     

Socio-cultural dynamics of female genital cutting: research findings, gaps, and directions

The goal of abolishing female genital cutting (FGC, or also FGM or 'female circumcision') requires that the socio-cultural dynamics of the practice be well understood if behavioural change is to be accomplished. This paper, based on the literature and the author's ethnographic research in Sudan, reports on the research issues of studying the variation in and complexity of cutting practices and their cultural correlates, arguing for multiple approaches and methods. It highlights directions for future research.     

Morbidity and mortality associated with renal insufficiency and endovascular repair of abdominal aortic aneurysms: a 5-year experience

To evaluate the outcome of patients with renal insufficiency undergoing endovascular repair of abdominal aortic aneurysm (AAA), data were prospectively collected between 1998 and 2003 on patients undergoing elective repair of their AAA with a stent graft. The patients were divided into 2 groups: those with serum creatinine (Crs) concentrations <1.2 (Group A) and those with Crs > or =1.2 mg/dL not requiring hemodialysis (Group B). The outcomes of the procedure for these 2 groups were compared. Different variables that existed between the 2 groups and contributed to mortality included estimated blood loss (EBL), volume of contrast used in the operating room, incidence of diabetes (DM), tobacco use, and history of myocardial infarction (MI). In total, 213 patients underwent elective repair of their AAA with use of a stent graft: 61% who had a Crs <1.2 mg/dL (Group A) and 39% who had a Crs > or =1.2 mg/dL not requiring dialysis (Group B). Among 129 patients with normal renal function there was an 18.6% complication rate and 1.6% mortality rate. Of 83 patients with renal insufficiency not on hemodialysis 30.1% (Fisher's Exact Test = 0.076) had 1 or more complications and there was a 6% (Fisher's Exact Test = 0.166) mortality rate. One patient in Group A (0.8%) progressed to hemodialysis and 5 (6%) patients in Group B progressed to end-stage renal disease requiring hemodialysis (p=0.068). A statistically significant higher proportion of the patients in Group B had a history of MI (p<0.001). There was no difference in the amount of EBL between the 2 groups, but a significantly lower amount of contrast (p<0.05) was used in patients with renal insufficiency.     

Interleukin-6 alters the cellular responsiveness to clopidogrel, irinotecan, and Oseltamivir by suppressing the expression of Carboxylesterases HCE1 and HCE2

Carboxylesterases constitute a class of enzymes that play important roles in the hydrolytic metabolism of drugs and other xenobiotics, patients with liver conditions such as cirrhosis show increased secretion of proinflammatory cytokines [e. g., interleukin-6 （IL- 6）] and decreased capacity of hydrolysis. In this sfudy, we provide a molecular explanation linking cytokine secretion directly to the decreased capacity of hydrolytic biotransformation. In both primary hepatocytes and HepG2 cells, treatment with IL-6 decreased the expression of human carboxylesterases HCE1 and HCE2 by as much as 60%. The decreased expression occurred at both mRNA and protein levels, and it was confirmed .by enzymatic assay. In cotransfection experiments, both HCE1 and HCE2 promoters were significantly repressed, and the repression was comparable with the decrease in HCE1 and HCE2 mRNA, suggesting that transrepression is responsible for the suppressed expression. In addition, pretreatment with IL-6 altered the cellular responsiveness in an opposite manner of overexpression of HCE1 and HCE2 toward various ester therapeutic agents （ e. g., clopidogrel）. Transfection of HCE1, for example, decreased the cytotoxicity induced by antithrombogenic agent clopidogrel, whereas pretreatment with IL-6 increased the cytotoxicity. Such a reversal was observed with other ester drugs, including anticancer agent irinotecan and anti-influenza agent oseltamivir. The altered cellular responsiveness was observed when drugs were assayed at sub-and low-micromolar concentrations, suggesting that suppressed expression of carboxylesterases by IL-6 has profound pharmacological consequences, particularly with those that are hvdrolvzed in an isoform-specific manner.

Early postoperative hyperglycaemia is not a risk factor for infectious complications and prolonged in-hospital stay in patients undergoing oesophagectomy: a retrospective analysis of a prospective trial

Introduction  

Treating hyperglycaemia in hospitalized patients has proven to be beneficial, particularly in those with obstructive vascular disease. In a cohort of patients undergoing resection for oesophageal carcinoma (a group of patients with severe surgical stress but a low prevalence of vascular disease), we investigated whether early postoperative hyperglycaemia is associated with increased incidence of infectious complications and prolonged in-hospital stay.
