Predictors of in-hospital mortality in a cohort of people living with HIV (PLHIV) admitted to an academic medical intensive care unit from 2009 to 2014: A retrospective cohort study.

Outcomes for critically ill people living with human immunodeficiency virus (PLHIV) have changed with the use of antiretroviral therapy (ART). To identify these outcomes and correlates of mortality in a contemporary critically ill cohort in an urban academic medical center in Baltimore, a city with a high burden of HIV, we conducted a retrospective cohort study of individuals admitted to a medical intensive care unit (MICU) at a tertiary care center between 2009 and 2014. PLHIV who were at least 18 years of age with an index MICU admission of ≥24 hours during the 5-year study period were included in this analysis.

Testing modality associated with fast-track ART initiation in Botswana.

Objectives: The aim of this study was to identify community testing modalities associated with fast-track ART initiation in Botswana.

Methods: We conducted a retrospective cohort study that included all Botswana citizens 15 years or older who were newly identified as HIV-positive from 1 May 2017 to 31 January 2019, in Mahalapye and Southern districts. We used Poisson regression with robust error variance and generalised linear mixed models to control for cluster effects to model risk of ART initiation within 7 and 30 days of HIV diagnosis, testing modality factors.

Subacute Polymicrobial Bacterial Pericarditis Mimicking Tuberculous Pericarditis: A Case Report.

BACKGROUND Bacterial pericarditis can present a diagnostic challenge due to the difficulty of obtaining tissue for bacterial identification. This report is of a 34-year-old man who presented with fever and cough. Diagnosis was initially delayed without a tissue sample, but the patient was later found to have polymicrobial bacterial pericarditis.

Pathophysiology and Treatment Options for Hepatic Fibrosis: Can It Be Completely Cured?

Hepatic fibrosis is a dynamic process that occurs as a wound healing response against liver injury. During fibrosis, crosstalk between parenchymal and non-parenchymal cells, activation of different immune cells and signaling pathways, as well as a release of several inflammatory mediators take place, resulting in inflammation. Excessive inflammation drives hepatic stellate cell (HSC) activation, which then encounters various morphological and functional changes before transforming into proliferative and extracellular matrix (ECM)-producing myofibroblasts.

Challenges in the diagnosis of tuberculous meningitis.

Tuberculosis (TB) continues to pose a significant public health problem. Tuberculous meningitis (TBM) is the most severe form of extra-pulmonary TB. TBM carries a high mortality rate, including for those receiving treatment for TB.

Is the Trigger in the Crohn's Disease Spectrum?

We present and discuss a 30-month investigation of a patient that presented with abdominal pain, postprandial diarrhea, bloating, and night sweats and was treated for Crohn's disease without significant improvement. The patient underwent an ileocecetomy with removal of an atonic segment with resolution of functional gastrointestinal symptoms, but profound night sweats continued postoperatively. The patient was presumptively treated for a mixed mycobacterial infection, blood cultures later grew (MAP), and she improved over time.

Clinical characteristics of critically ill patients with suspected influenza during the 2009-10 and 2013-14 outbreaks.

Purpose: Pandemic influenza A pdm09 (pH1N1) virus was the predominant isolate identified during the 2009-10 and 2013-14 influenza outbreaks, causing significant morbidity and mortality. We describe clinical characteristics of critically ill patients during 2 pH1N1 outbreaks.

Methods: Single-center, retrospective cohort study of patients admitted to the intensive care unit receiving oseltamivir for suspected influenza during 2 outbreak periods.

Identification of mycobacteria in solid-culture media by matrix-assisted laser desorption ionization-time of flight mass spectrometry.

Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has recently been introduced into the clinical microbiology laboratory as a rapid and accurate method to identify bacteria and yeasts. In this paper we describe our work on the use of MALDI-TOF MS for the identification of mycobacterial isolates. We developed a protocol for protein extraction from mycobacteria and utilized it to construct a database containing 42 clinically relevant type and reference strains of mycobacteria.
