ABSTRACT
OBJECTIVE: Critical illness causes a decrease in serum free triiodothyronine (T3) levels. This condition, known as nonthyroidal illness syndrome (NTIS), is associated with poor outcomes. The association of NTIS and outcomes in patients in the intensive care unit (ICU) requiring mechanical ventilation has not been well studied. This study aimed to determine the impact of NTIS on the outcomes of these patients. METHODS: This prospective study included 162 patients in the ICU who underwent mechanical ventilation. Serum free T3 levels were tested on the day of initiation of mechanical ventilation. The rates of in-hospital mortality and ventilator-free days (VFDs) at day 28 after the initiation of mechanical ventilation were compared between patients with low (<2.3 pg/mL) and normal (≥2.3 pg/mL) free T3 levels. Patients who died while on mechanical ventilation were assigned a VFD of 0. RESULTS: Low T3 was present in 60% of study patients. The in-hospital mortality rate of the entire cohort was 39%, and the mean and median VFDs at day 28 were 13.5 and 21 days, respectively. Compared to patients with normal free T3, patients with low free T3 had higher in-hospital mortality (52% vs 19%, P < .001) and less mean and median VFDs at day 28 (10.7 vs 18 and 0 vs 23, respectively. P < .001 for both mean and median VFDs). CONCLUSIONS: The presence of low T3 due to NTIS in patients in the ICU requiring mechanical ventilation is associated with poor outcomes.

OBJECTIVE: To assess the role for intravenous fluid (IVF) resuscitation in the postarrest state. Primary outcome was survival to hospital discharge and 30-day mortality. Secondary outcomes were associations with amount of vasopressor use and mechanical ventilation days. DESIGN: Retrospective study design. SETTING: Single-center tertiary hospital in Philadelphia, Pennsylvania. PATIENTS: All patients admitted to the intensive care unit between 2018 and 2019. INTERVENTIONS: Patients were divided into two groups based on amount of IVF received within 24âh <30âmL/kg (restricted) and over 30âmL/kg (liberal). MEASUREMENTS AND MAIN RESULTS: A total of 264 patients were included in the study, with 200 included in the restrictive (<30âmL/kg) group and 64 included in the liberal (>30âmg/kg) group. There was no difference in 30-day mortality between the two groups with 146 (73%) deaths in the restrictive groups and 44 (69%) deaths in the liberal group (Pâ=â0.53). There was also no significant difference between those who survived to hospital discharge in the liberal and restrictive groups on Kaplan-Meier analysis (Log-rankâ=â1.476 Pâ=â0.224). However, there was a significant difference between restrictive and liberal groups with the duration of mechanical ventilation (4â±â6 days vs. 6â±â9 days; Pâ=â0.03) and in the rates of two or more vasopressor use (38% vs. 59%; Pâ=â0.002). End-stage renal disease (ESRD) (ORâ=â2.39; Pâ=â0.03) and volume of fluids in mL/kg/24âh (ORâ=â1.025; Pâ<â0.0001) were independently associated with higher vasopressor need. Volume of fluid in mL/kg/24âh (Pâ=â0.01), ESRD (Pâ=â0.015), and chronic obstructive pulmonary disease (Pâ=â0.04) were significantly associated with duration of mechanical ventilation, even after adjusting for demographic factors, comorbidities, and mortality. CONCLUSIONS: A liberal strategy of IVF used in resuscitation after cardiac arrest is not associated with higher mortality. However, it predicts higher vasopressor use and duration of mechanical ventilation.

Coxsackie viruses are enteroviruses most common in children. Coxsackie B viral infections often present with biphasic fever, headache, pharyngitis, nausea/vomiting, diarrhea and a maculopapular rash that spares the palms and soles. These clinical features may be present in other viral infections. We present a case of a hospitalized adult with rash and fever with highly elevated ferritin levels later found to be due to Coxsackie B5. We believe this is the first case of Coxsackie B infection with otherwise unexplained highly elevated ferritin levels.
