Randomized Controlled Trial Multicenter Study
Polysomnographic Endotyping to Select Patients with Obstructive Sleep Apnea for Oral Appliances.
Rationale: Oral appliance therapy is efficacious in many patients with obstructive sleep apnea (OSA), but prediction of treatment outcome is challenging. Small, detailed physiological studies have identified key OSA endotypic traits (pharyngeal collapsibility and loop gain) as determinants of greater oral appliance efficacy. Objectives: We used a clinically applicable method to estimate OSA traits from routine polysomnography and identify an endotype-based subgroup of patients expected to show superior efficacy. ⋯ Differences persisted after adjusting for clinical covariates (including baseline AHI, body mass index, and neck circumference). Conclusions: Quantifying OSA traits using clinical polysomnography can identify an endotype-based subgroup of patients that is highly responsive to oral appliance therapy. Prospective validation is warranted.

Multicenter Study
Survivors of Critical Illness and Their Relatives. A Qualitative Study on Hospital Discharge Experience.
Rationale: To target rehabilitation needs of survivors of critical illness and their relatives in a timely and adequate manner, a thorough needs assessment is recommended when hospital discharge planning is initiated. In light of existing evidence on physical and psychological consequences of critical illness for patients and family, it is currently unclear if current hospital discharge procedures suffice to meet the needs of this group. Objectives: To explore hospital discharge experience and to identify perceived barriers and enablers for a positive transition experience from hospital to home or rehabilitation facility as perceived by survivors of critical illness and their families. ⋯ Thematic analyses led to identification of seven key concepts, representing barriers and enablers to a positive transition experience. "Existing in a fragmented reality," "being overlooked," and "feeling disqualified" were identified barriers and "feeling empowered," "encountering empathic and expert professionals," "managing recovery expectations," and "family engagement" were identified as enablers for a positive perceived transition experience. Conclusions: Findings of this study suggest that current hospital discharge practice for survivors of critical illness is driven by speed and efficiency, rather than by individual needs assessments, despite advocacies for patient- and family-centered care. Discharge strategies should be customized to facilitate adequate and comprehensive assessment of aftercare needs, conducted at the right time and within the right context, encouraging empowerment and a positive perceived transition from hospital to home.

Rationale: The oropharyngeal microbiome is a primary source of lung microbiota, contributes to lower respiratory infection, and is also a driver of oral health. Objectives: We sought to understand oropharyngeal microbial communities in advanced lung disease, community dynamics after lung transplantation, and ecological features of dysbiosis. Methods: Oropharyngeal wash samples were obtained from individuals with end-stage disease awaiting transplantation (n = 22) and longitudinally from individuals at 6 weeks, 3 months, and 6 months after transplantation (n = 33), along with healthy control subjects (n = 14). ⋯ Conclusions: End-stage lung disease is associated with marked upper respiratory tract dysbiosis involving both community structure and respiratory metabolism profiles of constituent bacteria. Dynamic changes occur after lung transplantation, with partial normalization early but later appearance of severe dysbiosis similar to pretransplant patients. Aberrant oropharyngeal communities may predispose to abnormal lung microbiota and infection risk both in advanced lung disease and after transplantation.

Rationale: Older adults with chronic obstructive pulmonary disease (COPD) are at substantially increased risk for medication-related adverse events. Two frequently prescribed classes of drugs that pose a particular risk to this patient group are opioids and benzodiazepines. Research on this topic has yielded conflicting findings. ⋯ Conclusions: Among older adults with COPD, use of opioid and benzodiazepine medications alone or in combination were associated with increased adverse respiratory events. The adverse effects of these medications were not exacerbated in patients with COPD-OSA overlap syndrome. However, the adverse impact of dual opioid and benzodiazepine was greater in patients with high-complexity COPD.
