Human spaceflight is entering a time of markedly increased activity fueled by collaboration between governmental and private industry entities. This has resulted in successful mission planning for destinations in low Earth orbit, lunar destinations (Artemis program, Gateway station) as well as exploration to Mars. ⋯ This chapter will cover clinically important aspects relevant to lung function in a normally proceeding mission; emergency scenarios such as decompression, fire, etc., will not be covered as these are beyond the scope of this review. To date, participation in commercial spaceflight by those with pre-existing chronic medical conditions is very limited, and hence, close collaboration between practicing pulmonary specialists and aerospace medicine specialists is of critical importance to guarantee safety, proper clinical management, and hence success in these important endeavors.

ReviewMotor-sparing peripheral nerve blocks for hip and knee surgery.
To summarize the recent literature describing and comparing novel motor-sparing peripheral nerve block techniques for hip and knee surgery. This topic is relevant because the number of patients undergoing same day discharge after hip and knee surgery is increasing. Preserving lower extremity muscle function is essential to facilitate early physical therapy for these patients. ⋯ The use of motor-sparing peripheral nerve block techniques enables early ambulation, adequate pain control, and avoidance of opioid-related side effects facilitating outpatient/ambulatory lower extremity surgery. Further studies of these techniques for continuous peripheral nerve block catheters are needed to assess if extended blockade continues to provide motor-sparing and opioid-sparing benefits.

Bronchiectasis in adults with chronic obstructive pulmonary disease (COPD) is associated with greater mortality. However, whether suspected bronchiectasis-defined as incidental bronchiectasis on computed tomography (CT) images plus clinical manifestation-is associated with increased mortality in adults with a history of smoking with normal spirometry and preserved ratio impaired spirometry (PRISm) is unknown. ⋯ National Heart, Lung, and Blood Institute.

Are there any correlations among the number of discopathy levels and pain intensity or disability in patients with symptomatic low back pain?
Low back pain (LBP) is considered a civilization disease that affects people in an increasing number. Discopathy (degeneration of intervertebral discs) is recognised as one of LBP causes. Still, the relationship between the number of discopathy levels and LBP remains unclear. The aim of this study was to evaluate the correlation between the number of discopathy levels with intensity of LBP, functional level and the degree of disability. ⋯ The number of levels of discopathy was depended on the age and BMI of the patients. It had no effect on pain intensity, range of rotational motion of the lumbar spine and functional status of patients. As the number of levels of discopathy increased, a higher degree of everyday disability was observed.

A 33-year-old man presented with a 10-day history of fever, dry cough, and dyspnea. He reported small amounts of frank hemoptysis that occurred several times a day for the past 3 days and a reduction in urine volume. ⋯ He had a medical history of childhood asthma and untreated hypertension for the past 2 years. He had no history of smoking, recent travel, medication use, or occupational inhalation.
