Successful Liver Transplantation in a Patient With Acute COVID-19 Infection and Acute Liver Failure: A Case Report.

Current liver transplantation societies recommend recipients with active coronavirus disease 2019 (COVID-19) be deferred from transplantation for at least 2 wks, have symptom resolution and at least 1 negative severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test.1 This approach does not address patients who require urgent transplantation and will otherwise die from liver failure. We report a successful orthotopic liver transplant (OLT) in a patient with active COVID-19 infection. This is only the second to be reported worldwide and the first in Canada.

A Detailed Review of Critical Care Considerations for the Pregnant Cardiac Patient.

Maternal cardiovascular disease is a leading cause of maternal death worldwide and recently, maternal mortality has increased secondary to cardiovascular causes. Maternal admissions to critical care encompass 1%-2% of all critical care admissions, and although not common, the management of the critically ill pregnant patient is complex. Caring for the critically ill pregnant cardiac patient requires integration of pregnancy-associated physiologic changes, understanding pathophysiologic disease states unique to pregnancy, and a multidisciplinary approach to timing around delivery as well as antenatal and postpartum care. Herein we describe cardiorespiratory changes that occur during pregnancy and the differential diagnosis for cardiorespiratory failure in pregnancy. Cardiorespiratory diseases that are either associated or exacerbated by pregnancy are highlighted with emphasis on perturbations secondary to pregnancy and appropriate management strategies. Finally, we describe general management of the pregnant cardiac patient admitted to critical care.

Case Fatality and Adverse Outcomes Are Reduced in Pregnant Women With Severe Sepsis or Septic Shock Compared With Age-Matched Comorbid-Matched Nonpregnant Women.

OBJECTIVES: Case fatality in pregnancy-associated severe sepsis or septic shock appears reduced compared with nonpregnant women with severe sepsis or septic shock. It remains unclear if this difference is due to pregnancy or better baseline health status, among others. Our study compared adverse outcomes of pregnancy-associated severe sepsis or septic shock with nonpregnant women with severe sepsis or septic shock while controlling for age and chronic comorbidities. DESIGN: Retrospective cohort study. SETTING: Nationwide Inpatient Sample, a stratified sample of 20% acute care hospital admissions in the United States. Each entry includes patient and hospital characteristics as well as International Classification of Diseases, 9th revision, Clinical Modification, diagnoses and procedures. SUBJECTS: Women of childbearing age (15-44 yr) with severe sepsis or septic shock-related hospitalizations during 1998-2012 identified using International Classification of Diseases, 9th revision, Clinical Modification, codes. OUTCOMES: Case fatality, hospital length of stay, length of stay until death, number of organ failures, rates of mechanical ventilation, and hemodialysis were compared in women according to pregnancy status, controlling for age, and chronic comorbidities. MEASUREMENTS AND MAIN RESULTS: We identified 5,968 pregnancy-associated severe sepsis or septic shock and 85,240 nonpregnant women with severe sepsis or septic shock hospitalizations. Crude case fatality of pregnancy-associated severe sepsis or septic shock (9.6%) was lower than nonpregnant women with severe sepsis or septic shock (16.8%). The rate ratio for case fatality adjusted for socioeconomic status and race was 0.57 (95% CI, 0.52-0.62) while sequential adjustments for age and chronic comorbidities did not eliminate the association (rate ratio, 0.62 [95% CI, 0.57-0.68]) and 0.63 [95% CI, 0.57-0.68], respectively). Pregnancy-associated severe sepsis or septic shock was associated with shorter hospital length of stay (-0.83 d [95% CI, -1.32 to -0.34 d]), longer length of stay until death (2.61 d; [95% CI, 1.28-3.94 d]), and fewer organ failures (rate ratio, 0.95 [95% CI, 0.94-0.97]). CONCLUSIONS: Case fatality and adverse outcomes are reduced in women with pregnancy-associated severe sepsis or septic shock compared with nonpregnant women with severe sepsis or septic shock, and this is not explained by differences in age or chronic comorbidities alone. A less severe presentation of sepsis or protective effect of pregnancy may account for the difference observed with pregnancy-associated severe sepsis or septic shock.

Premature Spinal Bone Loss in Women Living with HIV is Associated with Shorter Leukocyte Telomere Length.

With advances in combination antiretroviral therapy (cART), people living with HIV are now surviving to experience aging. Evidence suggests that individuals living with HIV are at greater risk for low bone mineral density (BMD), osteoporosis, and fractures. Better understanding of the pathophysiology of bone health in women living with HIV (WLWH) is important for treatment strategies. The goal of this study was to explore new biological factors linked to low BMD in WLWH. Standardized BMD measures of WLWH were compared to reference values from an unselected population of women from the same geographical region of the same age range. Linear regression analysis was used to assess relationships among health-related characteristics, cellular aging (measured by leukocyte telomere length; LTL), cART, and BMD of WLWH. WLWH (n = 73; mean age 43 ± 9 years) had lower BMD Z-scores at the lumbar spine (LS) (mean difference = -0.39, p < 0.001) and total hip (TH) (-0.29, p = 0.012) relative to controls (n = 290). WLWH between 50 and 60 years (n = 17) had lower Z-scores at the LS (p = 0.008) and TH (p = 0.027) compared to controls (n = 167). Among WLWH, LS BMD was significantly associated with LTL (R² = 0.09, p = 0.009) and BMI (R² = 0.06, p = 0.042). Spinal BMD was adversely affected in WLWH. Reduction of LTL was strongly associated with lower BMD and may relate to its pathophysiology and premature aging in WLWH.
