Management of Mycobacterium avium complex (MAC) lung disease is complicated, frequently unsuccessful, and frustrating to patients and clinicians. The initial treatment effort may not be directed solely at MAC infection, rather it is often initiating airway clearance measures for bronchiectasis. The next important steps are deciding who to treat and when to initiate therapy. ⋯ Microbiologic recurrences due either to new infection or treatment relapse/failure are common and require the same level of rigorous assessment and clinical judgment for determining their significance as initial MAC isolates. In summary, treatment of patients with MAC lung disease is rarely straight forward and requires familiarity with multiple factors directly and indirectly related to MAC lung disease. The many nuances of MAC lung disease therapy defy simple treatment algorithms; however, with patience, attention to detail, and perseverance, the outcome for most patients is favorable.

Comparative Effectiveness of Heart Rate Control Medications for the Treatment of Sepsis-Associated Atrial Fibrillation.
Atrial fibrillation (AF) with rapid ventricular response frequently complicates the management of critically ill patients with sepsis and may necessitate the initiation of medication to avoid hemodynamic compromise. However, the optimal medication to achieve rate control for AF with rapid ventricular response in sepsis is unclear. ⋯ In a large cohort of patients with sepsis and AF with rapid ventricular response, a β-blocker treatment strategy was associated with improved HR control at 1 h, but generally similar HR control at 6 h compared with amiodarone, calcium channel blocker, or digoxin.

Drowning is "the process of experiencing respiratory impairment from submersion or immersion in liquid." According to the World Health Organization, drowning claims the lives of > 40 people every hour of every day. Drowning involves some physiological principles and medical interventions that are unique. It occurs in a deceptively hostile environment that involves an underestimation of the dangers or an overestimation of water competency. ⋯ Ventilation therapy should achieve an intrapulmonary shunt ≤ 20% or Pao2:Fio2 ≥ 250. Premature ventilatory weaning may cause the return of pulmonary edema with the need for re-intubation and an anticipation of prolonged hospital stays and further morbidity. This review includes all the essential steps from the first call to action until the best practice at the prehospital, ED, and hospitalization.

Change is a fact of life; the absence of change creates stagnation. This is perhaps especially true in health care, where progress in treating disease depends on innovation and progress. At the same time, change is often uncomfortable. ⋯ Finally, physicians' avidity for change is framed by two opposing vectors. On the one hand, physicians share in the general human aversion to change. On the other hand, physicians are data-reverent and also wish to do their best for patients, which encourages their embrace of ever-increasing evidence and change.

The renin-angiotensin-aldosterone system (RAAS) contributes to pulmonary hypertension (PH) pathogenesis. Although animal data suggest that RAAS inhibition attenuates PH, it is unknown if RAAS inhibition is beneficial in PH patients. ⋯ ACEI and ARB use is associated with lower mortality in veterans with PH. AA use is a marker of disease severity in PH. ACEIs and ARBs may represent a novel treatment strategy for diverse PH phenotypes.
