For patients in shock, decisions regarding administering or withholding IV fluids are both difficult and important. Although a strategy of relatively liberal fluid administration has traditionally been popular, recent trial results suggest that moving to a more fluid-restrictive approach may be prudent. The goal of this article was to outline how whole-body point-of-care ultrasound can help clarify both the possible benefits and the potential risks of fluid administration, aiding in the risk/benefit calculations that should always accompany fluid-related decisions.

The bedside encounter between a patient and physician remains the cornerstone of the practice of medicine. However, physicians and trainees spend less time in direct contact with patients and families in the modern health care system. The current pandemic has further threatened time spent with patients. This lack of time has led to a decline in clinical skills and a decrease in the number of faculty members who are confident in teaching at the bedside. We offer several strategies to get physicians and trainees back to the bedside to engage in clinical skills teaching and assessment. We recommend that providers pause before bedside encounters to be present with patients and learners and to develop clear goals for a bedside teaching session. We suggest that clinical teachers practice an evidence-based approach, which includes an hypothesis-driven physical examination. We encourage the use of point-of-care technology to assist in diagnosis and to allow learners to calibrate traditional physical examination skills with real-time visualization of disease. Tools like point-of-care ultrasound can be powerful levers to get learners excited about bedside teaching and to engage patients in their clinical care. We value telemedicine visits as unique opportunities to engage with patients in their home environment and to participate in patient-directed physical examination maneuvers. Finally, we recommend that educators provide feedback to learners on specific clinical examination skills, whether in the clinic, the wards, or during dedicated clinical skills assessments.

There are few clinically useful circulating biomarkers of lung function and lung disease. We hypothesized that genome-wide association studies (GWAS) of circulating proteins in conjunction with GWAS of pulmonary traits represents a clinically relevant approach to identifying causal proteins and therapeutically useful insights into mechanisms related to lung function and disease.

During exercise, dynamic hyperinflation (DH), measured by a reduction in inspiratory capacity (IC), increases exertional dyspnea and reduces functional capacity in many patients with severe COPD. Although noninvasive ventilation (NIV) during exercise can improve exercise duration, the effect on DH is unclear.

Improved prediction of the risk of early major bleeding in pulmonary embolism (PE) is needed to optimize acute management.

Previous studies reported a strong association between sleepiness-related symptoms and comorbidities with poor cardiovascular outcomes among patients with moderate to severe OSA (msOSA). However, the validation of these associations in the Hispanic population from South America and the ability to predict incident cardiovascular disease remain unclear.

Idiopathic pulmonary fibrosis (IPF) is a progressive fibrosing interstitial lung disease associated with significant morbidity and mortality. Nintedanib and pirfenidone are two antifibrotic medications currently approved for slowing the rate of lung function decline in IPF, but data on treatment effect on mortality and risk of acute exacerbation (AE) remains limited or unknown.
