Accurate risk prediction of exacerbations is pivotal in severe asthma management. Multiple risk factors are at play, but the pathway of risk prediction remains unclear.

Low spirometry testing rate for screening of chronic obstructive pulmonary disease (COPD) is partly attributed to complex procedures, stringent quality control requirements, and long examination times. Simplifying the spirometry protocol may increase the feasibility of COPD screening in community settings.

Limited real-world data exist on the health impacts of the Philips Respironics recall for positive airway pressure (PAP) devices.

Right heart catheterization (RHC) is the gold standard for the diagnosis of pulmonary hypertension (PH). There are variations in practice and several pitfalls introducing errors in diagnosis that can significantly impact treatment. Errors in assessing the correct pulmonary artery wedge pressure (PAWP) can significantly affect accurate classification of patients with pulmonary hypertension, and lead to potentially deleterious treatment decisions. This review focuses on best practices in RHC performance, emphasizing practical and pathophysiologic principles to obtain the most accurate result, as well as advanced applications in PH.

Despite the significant health and economic burden associated with obstructive sleep apnea (OSA) among civilians, little is known about this burden among active-duty military personnel.

The high incidence of bronchopulmonary dysplasia (BPD) continues to be a problem among extremely low-gestational-age neonates (ELGANs). Recent improvements in next-generation proteomics have provided opportunities to obtain new perspectives on the early detection of BPD. In this study, our main objectives were to study the proteomes of patients by collecting nasopharyngeal aspirate (NPA) samples and evaluate the differences between ELGANs with and without BPD at 1 week of life.

Preserved ratio impaired spirometry (PRISm) is regarded as a COPD precursor, but whether this varies by smoking status remains unclear.

From screening to treatment, the continuum of lung cancer reflects unequal access and delivery, with more vulnerable patients less able to receive high-quality care. Despite great advances in lung cancer care (eg, screening and nodule programs to identify early-stage disease and immune-mediated and targeted therapies for advanced-stage disease), disparities persist both in the United States and globally. In this narrative review, the spectrum of disparities that influence lung cancer care on a national scale, including race, ethnicity, age, socioeconomic status, geographic location, and insurance access, are explored. The review focuses on how disparities impact screening efforts and lung cancer treatments. Where data are available, trends on a global scale are addressed. Potential solutions are offered to address recognized disparities, primarily by identifying pertinent social determinants of health and launching multipronged interventions to improve the care of all patients with lung cancer.

Limited data exists to inform and appropriately counsel female lung transplant (LuT) recipients regarding post-transplant pregnancy.

A 7-year-old girl was referred to our vascular anomaly center for further evaluation of multiple lung nodules. These nodules were incidentally detected on a CT scan during hospitalization for treatment of mycoplasma pneumonia at another hospital. The biopsy results suggested the possibility of vascular tumors. Physical examination revealed clear breath sounds without rales. Furthermore, no skin lesions or other positive signs were observed. The patient was not receiving supplemental oxygen. Before she came to our center, the patient had received antibiotic treatment for mycoplasma pneumonia. The CT scan after recovery revealed that the multiple nodules in both lungs persisted despite the resolution of the infection.

A 4-year-old girl with ring chromosome 14, epilepsy, global developmental delay, and failure to thrive presented for a preoperative assessment for gastrostomy tube (G-tube) insertion and was incidentally found to be hypoxemic, with saturations of 81% in room air. There was no history of fever or upper respiratory tract infection symptoms; however, her parents described a progressive history of choking and emesis with feeds over 3 months. Chest radiograph demonstrated patchy alveolar opacities in the right lower and middle lobes. She was admitted to the hospital and treated with supplemental oxygen and IV ampicillin for a suspected aspiration pneumonia. On day 3 of her admission, because of persistent hypoxemia despite high-flow nasal cannula support at 2 L/kg/min with an Fio2 of 0.6 to 0.7, and frequent need for suctioning of thick yellow secretions, she was transferred to the PICU for escalation to noninvasive ventilation. Because of poor response after 7 days, and respiratory secretions showing moderate growth of Klebsiella oxytoca and light growth of Stenotrophomonas maltophilia, sulfamethoxazole-trimethoprim was added. Azithromycin was also started on day 8 to cover atypical pathogens, then discontinued when Mycoplasma pneumoniae polymerase chain reaction was negative.

With growing interest in a centralized approach to lung cancer screening (LCS), pooling current evidence to estimate its impact on annual adherence is essential for aligning practice with guideline recommendations.

Patients with interstitial lung disease (ILD) often receive care from general pulmonologists because geographic and financial barriers limit access to specialized care centers. However, graduating pulmonary fellows lack confidence in managing patients with ILD. Refining ILD education in pulmonary fellowship could address this gap, but what trainees must learn is not defined currently.

More than 600,000 adults in the United States experience an out-of-hospital or in-hospital cardiac arrest each year. Following resuscitation from cardiac arrest, most patients receive mechanical ventilation. The oxygenation target that optimizes neurologic outcomes following cardiac arrest is uncertain.

Pulmonary arterial hypertension (PAH) is a complex cardiopulmonary disease associated with exertional dyspnea and impaired health-related quality of life (HRQOL) despite medical therapy. Pulmonary rehabilitation (PR), a supervised exercise program for patients with chronic lung disease, improves symptoms, HRQOL and exercise capacity. Despite these benefits, there is a paucity of data regarding PR in PAH.

It remains challenging to safely and reliably biopsy peripheral pulmonary lesions (PPLs). Robotic-assisted bronchoscopy (RAB) is gaining adoption for navigation to PPLs. However, evidence from large studies remains limited.

Lung transplantation (LTx) remains the ultimate treatment for many patients with advanced lung disease. Although the age cutoffs for LTx have been debated due to variable outcomes, the number of LTx procedures performed on patients aged ≥ 65 years has significantly increased in recent decades, reflecting the realities of an aging demographic. This trend underscores the unique management challenges faced by this cohort and highlights the importance of addressing evidence gaps in their perioperative and postoperative care.

Between 2020 and 2022, the COVID-19 pandemic disrupted health and education. Many training institutions modified trainees' rotations, decreasing outpatient clinics while increasing inpatient and ICU time. Understanding the pandemic's impact on medical trainees' cognitive performance is essential for informing strategies and supporting trainee well-being during crises.

COPD is characterized by persistent inflammation that is responsible for remodeling the bronchovascular bundles (BVBs), which may lead to poor quality of life. Quantitative CT (QCT) scan textures of the lung can capture local disease patterns of inflammation and related respiratory morbidity.

The bidirectional relationship between frailty and COPD is documented. However, longitudinal studies examining the combined effects of genetic predisposition and preserved ratio impaired spirometry (PRISm) on frailty in COPD development are lacking.
