The Difficult Clinical Decision of Thrombolytic Therapy for Submassive Pulmonary Embolism in a Community Hospital.

Submassive or intermediate-risk pulmonary embolism (PE) occurs when an acute PE episode is associated with radiographic evidence of right heart strain without hemodynamic instability. Further risk stratification is important in determining whether systemic thrombolytic therapy should be administered when weighing the risks and benefits. It includes the risk of death from acute PE versus the risk of bleeding. This decision could be further complicated in institutions where there is a lack of complete therapeutic options, which increases the importance of the expertise of a pulmonologist or an intensivist to decide whether rescue reperfusion is needed. We describe the case of a 34-year-old female patient with a history of right thigh abscess and diabetes mellitus who was admitted for diabetic ketoacidosis (DKA) along right thigh abscess status post-incision and drainage. She had a syncopal episode and was found to have submassive PE with right heart strain with stable hemodynamics and oxygen requirement. She tolerated systemic thrombolytic therapy without complications with a drastic improvement in her cardiac function post-treatment.

Hello World Deep Learning in Medical Imaging.

There is recent popularity in applying machine learning to medical imaging, notably deep learning, which has achieved state-of-the-art performance in image analysis and processing. The rapid adoption of deep learning may be attributed to the availability of machine learning frameworks and libraries to simplify their use. In this tutorial, we provide a high-level overview of how to build a deep neural network for medical image classification, and provide code that can help those new to the field begin their informatics projects.

Identifying Patient and Provider-specific Gaps in Care Among Patients With Hepatitis B.

GOALS: To examine patient, provider, and health system barriers to clinical follow-up among US veterans with chronic hepatitis B virus (HBV). BACKGROUND: Studies have demonstrated deficiencies in clinical care and follow-up in HBV; however, patient, provider, and health-system barriers in non-Asian populations are understudied. STUDY: A retrospective cohort of 517 US veterans with chronic HBV at 3 diverse Veterans Affairs sites from 1999 to 2015. Laboratory testing and completion of clinical appointments were collected for 2 years following initial presentation. RESULTS: Among HBV patients, 36% had drug abuse, 41% alcohol misuse, and 45% had psychiatric disorders. Patients had an average of 4.4 primary care visits within 2 years of the index hepatitis B surface antigen positive result, 38% had psychiatry visits, 21% had a psychiatric hospitalization; 26% saw gastroenterology/hepatology specialists. Within 1 year of the index hepatitis B surface antigen positive result, 75% had alanine aminotransferase testing, 14% had HBV entered into the problem list, and 8% had serologic confirmation. In multivariable analyses, cirrhosis [odds ratio (OR)=3.42; 95% confidence interval (CI), 1.84-6.36] was associated with higher odds of appropriate laboratory testing, alcohol misuse (OR=0.45; 95% CI, 0.29-0.80) was associated lower odds. Cirrhosis (OR=2.03; 95% CI, 1.11-3.72) and ≥2 primary care visits per year (OR=1.06; 95% CI, 1.01-1.11) were associated with higher odds of completing gastroenterology/hepatology consultation, whereas ≥1 psychiatric hospitalization in 2 years was associated with lower odds (OR=0.53; 95% CI, 0.34-0.82). CONCLUSIONS: In a diverse cohort of veterans with high psychiatric comorbidity and substance abuse, important patient and provider factors influence appropriate follow-up care. Future studies should evaluate the impact of provider education and care coordination strategies in HBV.
