Completion of Colonoscopy After Positive Fecal Occult Blood Test Screening at a Community Health Center.

Introduction: Screening for colorectal cancer decreases mortality. Fecal occult blood testing (FOBT) decreases some barriers to screening, however positive results require colonoscopy. We evaluated factors associated with colonoscopy completion for community health center (CHC) patients after positive FOBT.

Optimizing the Synergistic Potential of Pseudo-Labels from Radiology Notes and Annotated Ground Truth in Identifying Pulmonary Opacities on Chest Radiographs for Early Detection of Acute Respiratory Distress Syndrome.

Acute Respiratory Distress Syndrome (ARDS) is a life-threatening lung injury, hallmarks of which are bilateral radiographic opacities. Studies have shown that early recognition of ARDS could reduce severity and lethal clinical sequela. A Convolutional Neural Network (CNN) model that can identify bilateral pulmonary opacities on chest x-ray (CXR) images can aid early ARDS recognition.

Uncertainty-Aware Convolutional Neural Network for Identifying Bilateral Opacities on Chest X-rays: A Tool to Aid Diagnosis of Acute Respiratory Distress Syndrome.

Acute Respiratory Distress Syndrome (ARDS) is a severe lung injury with high mortality, primarily characterized by bilateral pulmonary opacities on chest radiographs and hypoxemia. In this work, we trained a convolutional neural network (CNN) model that can reliably identify bilateral opacities on routine chest X-ray images of critically ill patients. We propose this model as a tool to generate predictive alerts for possible ARDS cases, enabling early diagnosis.

The Local Market of Major Teaching Hospitals.

Objective: The purpose of this study was to describe the local communities served by major teaching hospitals.

Methods: Using a dataset of hospitals around the United States provided by the Association of American Medical Colleges, we identified major teaching hospitals (MTHs) using the Association of American Medical Colleges' definition of those with an intern-to-resident bed ratio above 0.25 and more than 100 beds.

Frequency and outcomes of gastrointestinal symptoms in patients with Corona Virus Disease-19.

Objectives: To characterize the frequency and association of gastrointestinal (GI) symptoms with outcomes in patients with corona virus disease 2019  (COVID-19) admitted to the hospital.

Methods: Records were retrospectively collected from patients admitted to a tertiary care center in Washington, D.C.

Hair-Dye-Related Accidental Poisoning and Death.

Para phenylenediamine (PPD) is a common component of hair dye as well as temporary tattoos and is a well-known cause of type 4 hypersensitivity reactions from topical exposure. While there have been several cases reported in the literature describing toxicities following ingestion, there are a paucity of reports of severe systemic disease following topical exposure. Cases of PPD ingestion have been reported to present with angioedema-like reactions, often progressing to rhabdomyolysis and renal failure.

Emphysematous osteomyelitis of the clavicle: a pleural process?

Emphysematous osteomyelitis (EO) is a rare infection associated with intraosseous gas. EO is an often fatal disease with an estimated 34% mortality. We present a case of a 63-year-old man with sternoclavicular EO with pleural involvement and significant subcutaneous emphysema diagnosed by CT.

Catheter-Directed Thrombolytic Therapy in the Management of Massive Pulmonary Embolism in Pregnancy.

Background: Pulmonary embolism is one of the most common causes of maternal mortality and can be classified into low-risk, submassive, and massive. Three treatment options exist for massive pulmonary embolism in nonpregnant patients: thrombolysis, percutaneous catheter-based embolectomy, or surgical embolectomy; however, there is limited evidence to guide management of pulmonary embolism in pregnancy.

Case: We present a case of massive pulmonary embolism in pregnancy.
