Hospitalization Risk for Medicare Beneficiaries With Nontuberculous Mycobacterial Pulmonary Disease.
Nontuberculous mycobacterial pulmonary disease (NTM-PD) is an uncommon mycobacterial infection characterized by worsening lung function and increased health care resource utilization; however, the overall risk for hospitalization among patients with NTM-PD remains unclear. ⋯ Patients with NTM-PD were significantly more likely to be hospitalized, had greater annualized hospitalization rates, and had shorter time to hospitalization than age- and sex-matched control subjects without NTM-PD. These findings highlight the significantly increased burden of hospitalizations among patients with NTM-PD.

Lung disease after tuberculous confers significant morbidity. However, the determinants of persistent lung damage in TB are not well established. We investigated associations between TB-associated radiologic changes and sociodemographic factors, surrogates of bacillary burden, and blood inflammatory markers at initiation of therapy and after 1 month. ⋯ Persistent neutrophilic inflammation after 1 month of TB therapy is associated with poor radiologic outcome, suggesting a target for interventions to minimize lung disease after tuberculous.

A 39-year-old woman with systemic lupus erythematosus that was complicated by end-stage renal disease that had required a deceased donor renal transplant 16 years ago was referred for evaluation of chronic, nonproductive cough for 2 years. She was a lifetime nonsmoker whose condition was maintained on prednisone 5 mg daily, tacrolimus 3 mg twice day, mycophenolate mofetil 500 mg twice a day for her immunosuppression regimen, valacyclovir 500 mg twice a day for prophylaxis, and clonidine 0.1 mg daily and metoprolol succinate 100 mg twice daily for hypertension.

Case Reports
Successful Total Tracheal Replacement by Cryopreserved Aortic Allograft in a Patient Post-COVID-19 Infection.
This is the first report to our knowledge of a successful total tracheal replacement in a post-COVID-19 patient by cryopreserved aortic allograft. The graft was anastomosed to the cricoid and carina; a silicon stent was inserted to ensure patency. ⋯ Three weeks after surgery, the patient was discharged from hospital in excellent health, and was able to resume his normal lifestyle, work, and activity as an amateur cyclist. Two months after surgery, the patient assumes aerosol with saline solution three times per day and no other therapy; routine bronchoscopy to clear secretions is no longer needed.

A 22-year-old woman who was 36 weeks pregnant presented with a 4-day history of cough, hemoptysis, and exertional dyspnea. She had no fever, night sweats, or weight loss. ⋯ At that time, she had a transvaginal ultrasound scan that showed a gestational sac with no fetal movement. A post-abortion ultrasound scan revealed no residual fetal parts.
