Now we have MERCY
Beta-lactam antibiotics, including penicillin, carbapenems, and cephalosporins, exhibit time-dependent bacterial eradication. Prolonged infusions are thought to enhance the duration of effective bactericidal antibiotic exposure, decreasing the emergence of drug resistance due to reduced bacterial regrowth between doses – which may lead to cost savings by reducing drug acquisition costs and shortening hospital stays (Lodise TP…

Use of 6-minute walk distance as a clinical trial outcome in interstitial lung disease
Pulmonary arterial hypertension (PH) and more recently interstitial lung disease (ILD) trials use the 6-minute walk test (6MWT) as a primary outcome due to its ability to conveniently capture a patient’s functional capacity and quality of life. However, interpreting the 6MWT in complex and diverse diseases, such as ILD, presents significant challenges. A recent article…

CPAP in overlap syndrome: Unveiling the evidence
The overlap syndrome (OS), which refers to the co-occurrence of OSA and COPD, was first described by Flenley in 1985 (Flenley DC. Clin Chest Med. 1985;6[4]:651). Over the years, numerous studies have demonstrated an increased risk of hospitalization and mortality in patients with OS (Brennan M, et al. 2022;1-10). Despite these findings, limited evidence exists…

Home oxygen therapy: What does the data show?
Inhalers, nebulizers, antibiotics, and steroids – these are some of the most common tools in our pulmonary arsenal that we deploy on a daily basis. But, there is no treatment more fundamental to a pulmonary practitioner than oxygen. So how is it that something that naturally occurs and comprises 21% of ambient air has become…

Sepsis-induced cardiomyopathy: Is it time to establish a standard of care?
Sepsis and septic shock still carry high morbidity and mortality in ICU patients despite recent improvements in care. Sepsis-induced cardiomyopathy (SICM), which complicates greater than 10% of sepsis and septic shock cases, carries a worse prognosis and is often underrecognized. Unfortunately, no universal definition of SICM exists, making diagnosis and evaluation of novel therapeutic options…

NPV vs NIPPV
Noninvasive ventilation (NIV) is a ventilation modality that supports breathing by using mechanically assisted breaths without the need for intubation or a surgical airway. NIV is divided into two main types, negative-pressure ventilation (NPV) and noninvasive positive-pressure ventilation (NIPPV). NPV NPV periodically generates a negative (subatmospheric) pressure on the thorax wall, reflecting the natural breathing…

Responding to firearm violence in America
We think of disasters as sudden, calamitous events, but it does not take much imagination to recognize the loss of lives in America from firearm violence as a type of disaster. In 2020, 45,222 people died from gun-related injuries, an increase of 5,155 (14%) since 2019 (Kegler, et al. MMWR Morb Mortal Wkly Rep. 2022;71[19]:656). This is…

Increasing primary care doctors’ knowledge of IPF could speed up diagnoses, suggests white paper
Prompt diagnosis of idiopathic pulmonary fibrosis is essential to reduce mortality, and improving education of primary care providers can help, suggests a new white paper. The nonspecific nature of the symptoms of idiopathic pulmonary fibrosis (IPF) especially in early stages, and the relative rarity of IPF compared with other conditions that have similar symptoms, may…

ILD on the rise: Doctors offer tips for diagnosing deadly disease
Too often, when patients come to see Tejaswini Kulkarni, MD, with shortness of breath and cough and are diagnosed with interstitial lung disease (ILD), they are past the point when treatments would most benefit them. “There is definitely a delay from the time of symptom onset to the time that they are even evaluated for…
