Article Synopsis
  • Nocturia (waking up at night to urinate) and chronic insomnia often affect older adults together, leading to more severe sleep disturbances, yet treatments usually focus on one issue at a time.
  • A study involved older adults with both conditions to test a new treatment approach combining cognitive-behavioral therapy for insomnia and nocturia, as well as a control health education program.
  • Results showed that participants in the combined treatment group experienced a greater reduction in the number of nightly nocturia episodes compared to those in the control group over four months, suggesting the method's feasibility for future research.

Article Synopsis
  • Placebo effects are often seen in clinical trials for benzodiazepine receptor agonists, leading to recommendations for discontinuation of these medications in older adults and the use of cognitive behavioral therapy for insomnia (CBTI) instead.
  • This study aims to compare the effects of a masked tapering process combined with enhanced CBTI against standard CBTI with an unmasked taper in helping older adults discontinue benzodiazepine receptor agonists.
  • The primary outcome measured is the percentage of participants successfully discontinuing their medication after 6 months, with additional assessments of insomnia severity and short-term discontinuation rates.

Article Synopsis
  • Positive airway pressure (PAP) therapy is the standard treatment for obstructive sleep apnea (OSA), but many patients struggle to consistently use it; understanding their blood oxygen levels may help improve adherence.
  • This study investigates the feasibility and effectiveness of a program (mPAP) that integrates data from consumer wearable devices with PAP usage reports to enhance patient self-management of therapy.
  • The trial will involve 50 veterans with OSA who will be split into intervention and control groups to assess how well wearable device feedback influences their PAP usage over a 28-day period.

Background: Cognitive behavioral therapy for insomnia (CBT-I) is the gold-standard treatment for insomnia disorder in adults. Compared to young adults, older adults have increased risk for the development of conditions associated with chronic pain, which may impact the efficacy of CBT-I in improving insomnia symptoms in older adults. This study evaluated the effect of participant-rated pain on sleep-related outcomes of a supervised, non-clinician administered CBT-I program in older adult patients with chronic insomnia disorder.

Sleep disturbances and financial exploitation have both been linked to impaired cognitive ability, loneliness, and depressed mood in older adults, suggesting a potential role of sleep disturbances in increasing vulnerability to financial exploitation. We sought to identify evidence linking sleep disturbances to financial exploitation. We conducted a systematic search of MEDLINE, PubMed Central, and National Center for Biotechnology Information Bookshelf for relevant published articles on sleep and financial exploitation.

Study Objectives: Recent initiatives to discourage overprescription of sleep medications have increased awareness of their potential adverse effects; however, it is unknown whether these efforts translated into a decline in use of these medications in the United States. We assessed recent national trends in the use of medications used for sleep disturbance.

Methods: We used data from n = 29,400 participants in the 2013-2018 National Health and Nutrition Examination Survey.

Nocturia and chronic insomnia disorder are common conditions that frequently coexist in older adults. Existing medication treatments for each condition have risks, particularly in older adults. While treatment guidelines recommend starting with behavioural therapy for each condition, no existing program simultaneously addresses nocturia and insomnia.

Objectives: To measure the rate of benzodiazepine receptor agonist (BZA) dependence in older veterans with insomnia symptoms chronically using BZAs and to assess for associations between high posttraumatic stress disorder (PTSD) risk and BZA dependence.

Methods: A cross-sectional study was conducted among veterans aged 55 years and older with insomnia symptoms (current or historical) and chronic use of BZAs (≥3 months). Measurements included the Primary Care-PTSD screen (score >2 indicates high PTSD risk) and Benzodiazepine Dependence Questionnaire.

Deprescribing of medications such as benzodiazepines and benzodiazepine receptor agonists (z-drugs) can be a complex process that varies across practices, specialties, and health care systems. Care coordination among healthcare providers, patients, families, and other healthcare system components is critical to achieving high levels of deprescribing and person-centered care. We present a framework for promoting care coordination in the context of benzodiazepine/z-drug deprescribing.

Background: Nocturnal bladder symptoms and sleep disruption commonly coexist in middle-aged and older women. Although sleep disruption is often attributed to nocturnal bladder symptoms in women with overactive bladder syndrome, nonbladder factors also may influence sleep in this population. Many women with overactive bladder are eager to identify nonpharmacologic strategies for both bladder symptoms and sleep disruption, given the potential adverse effects of sedative and anticholinergic bladder medications in this population.

Study Objectives: Home sleep apnea testing (HSAT) is an efficient and cost-effective method of diagnosing obstructive sleep apnea (OSA). However, nondiagnostic HSAT necessitates additional tests that erode these benefits, delaying diagnoses and increasing costs. Our objective was to optimize this diagnostic pathway by using predictive modeling to identify patients who should be referred directly to polysomnography (PSG) due to their high probability of nondiagnostic HSAT.
