RESUMO
RATIONALE: Three-year continuous positive airway pressure (CPAP) therapy termination rates are up to 50%, and therapy termination is associated with higher all-cause mortality and incident cardiovascular event risk. OBJECTIVE(S): This study investigated the impact of CPAP therapy termination in the first year on long sick leave leading to permanent work disability in patients with obstructive sleep apnea (OSA) based on data from the nAtionwide cLAimS data laKe for sleep Apnoea (ALASKA). METHODS: French national health insurance reimbursement system (SNDS) data were analyzed for all adults with OSA aged ≤62 years who started CPAP therapy in France in 2015/2016. CPAP therapy termination was defined as the cessation of CPAP reimbursements triggered by the respiratory physician/sleep specialist in charge of follow-up. Individuals who terminated therapy were compared with those who continued to use CPAP. The primary outcome was sick leave ultimately leading to permanent work disability. A multivariable Finn and Gray model, adjusted for age, sex, cardiovascular/metabolic comorbidities, depression, and CPAP prescriber clinical specialty was used to assess the risk of long-term sick leave leading to permanent work disability over 3 years' follow-up. RESULTS: The analysis included 174,270 individuals (median age 52.0 years [interquartile range 44.0-57.0], 67.5% male). The 1-year CPAP therapy termination rate was 22.3%. The proportion of individuals with long-term sick leave leading to permanent work disability was significantly higher in the CPAP termination versus continuation group (0.60% vs. 0.52%; p=0.042). In an adjusted multivariable Cox model, CPAP termination was associated with an increased risk of permanent work disability (hazard ratio [HR] 1.21, 95% confidence interval [CI] 1.04-1.41; p=0.01), primarily in the subgroup aged >55 years (HR 1.41, 95% CI 1.06-1.87; p=0.02). CONCLUSIONS: These real-world data from a comprehensive, unbiased database highlight the potential occupational impact of CPAP therapy termination.
RESUMO
BACKGROUND: Adaptive pressure control-continuous mandatory ventilation (APC-CMV) is a frequently utilized ventilator mode in ICU settings. This analysis compared APC-CMV and traditional volume control-continuous mandatory ventilation (VC-CMV) mode, describing factors associated with initiation, maintenance, and changes in settings of each mode. METHODS: We analyzed ventilator data from a retrospective electronic health record data set collected as part of a quality improvement project in a single academic ICU. The majority ventilator mode was defined as the mode comprising the highest proportion of mechanical ventilation time. Multivariable logistic regression was used to identify variables associated with initial and majority APC-CMV or VC-CMV modes. Wilcoxon rank-sum tests were used to compare ventilator setting changes/d and sedation as a function of APC-CMV and VC-CMV majority modes. RESULTS: Among 1,213 subjects initiated on mechanical ventilation from January 2013-March 2017, 68% and 24% were initiated on APC-CMV and VC-CMV, respectively, which composed 62% and 21% of the majority ventilator modes. Age, sex, race, and ethnicity were not associated with the initial or majority APC-CMV or VC-CMV modes. Subjects initiated on APC-CMV spent 88% of the mechanical ventilation time on APC-CMV mode. Compared to VC-CMV, subjects with APC-CMV majority mode experienced more ventilator setting changes/d (1.1 vs 0.8, P < .001). There were no significant differences in sedative medications when comparing subjects receiving APC-CMV versus VC-CMV majority modes. CONCLUSIONS: APC-CMV was highly utilized in the medical ICU. Subjects on APC-CMV had more ventilator setting changes/d than those on VC-CMV. APC-CMV offered no advantage of reduced setting adjustments or less sedation compared to VC-CMV.
RESUMO
BACKGROUND: The term "Overlap Syndrome" (OS) describes the presence of both chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) in a single individual. Excessive daytime sleepiness (EDS) is a common symptom of OS shown to be associated with an increased risk of cardiovascular disease (CVD) that could be reduced through exercise. Thus, we propose to investigate a novel exercise intervention in individuals with the EDS-OS phenotype as they are at highest risk of CVD yet have the greatest barriers to exercise. METHODS: We will conduct a single-site, randomized, two-arm, parallel group-controlled exercise trial in individuals with EDS-OS. The Epworth Sleepiness Scale (ESS) will be assessed at baseline. Individuals with OS and the EDS-OS phenotype (ESS >10) (n = 46) will be randomized to a moderate intensity interval training (MIIT, i.e. intervals of 5 min at 50% VO2peak followed by 3 min of active recovery at 10% VO2peak) or a control group of standard of care. We will investigate if MIIT intervention decreases the risk of CVD in EDS-OS, which will be assessed by: 1) quality of life, measured by the 36-Item Short Form Health Survey; 2) physical activity, measured by daily step counts; and 3) cardiovascular health, assessed as VO2peak, flow-mediated dilation and serum high sensitivity C-reactive protein, lipids, and glucose. CONCLUSION: Our findings will guide future development and implementation of exercise interventions that could reduce the risk of CVD in the understudied EDS-OS phenotype.
RESUMO
AIM: Intraventricular haemorrhage (IVH) and periventricular leukomalacia (PVL) in preterm infants are associated with an increased risk of long-term neurodevelopmental impairments (NDI) and cerebral palsy (CP). However, little is known about their impact on early neurodevelopmental outcomes despite increasing evidence highlighting the feasibility and importance of early NDI/CP diagnosis. We aimed to determine the early neurodevelopmental outcomes of preterm infants with IVH and PVL. METHODS: This was a retrospective single-centre cohort study of preterm infants born at <29 weeks gestation or <1000 g birth weight who attended an Early Neurodevelopment Clinic at 3 to 4 months of corrected age. Primary outcomes of early NDI and CP/high-risk CP diagnoses based on Prechtl's General Movements Assessment and the Hammersmith Infant Neurological Examination were compared between infants without IVH and infants with mild IVH (grades I-II), severe IVH (grades III-IV), and severe brain injury (SBI; severe IVH or cystic PVL). RESULTS: Of 313 infants, 52.1% (n = 163), 41.2% (n = 129), 6.7% (n = 21) and 8.6% (n = 27) had no IVH, mild IVH, severe IVH and SBI, respectively. The adjusted odds of early CP/high-risk CP diagnosis were significantly higher in infants with severe IVH (aOR 6.07, 95% CI 1.50-24.50) and SBI (aOR 15.28, 95% CI 3.70-63), but not in those with mild IVH (aOR 1.24, 95% CI 0.49-3.10). However, the adjusted odds of any early NDI were similar across groups. CONCLUSION: Preterm infants with severe IVH and SBI are at increased risk of early CP/high-risk of CP diagnosis at 3 to 4 months of corrected age.
RESUMO
INTRODUCTION: In patients with obstructive sleep apnea (OSA), novel metrics such as hypoxic burden (HB) and sleep apnea-specific pulse-rate response (ΔHR) may better correlate with cardiovascular diseases (CVD) than the apnea-hypopnea index (AHI). This manuscript aims to assess the correlation between ΔHR and HB with subclinical atherosclerosis in patients with OSA, testing the hypothesis that elevated ΔHR and HB are associated with subclinical atherosclerosis development. METHODS: In a prospective study, individuals aged 20-65 years with suspected OSA without known comorbidities were consecutively recruited and defined as OSA (AHI≥5events/h) or healthy controls. Using bilateral carotid ultrasonography, common carotid intima-media thickness (CIMT) was assessed and the identification of at least one atheromatous plaque defined the presence of subclinical atherosclerosis. ΔHR, and HB were derived from pulse-oximetry. RESULTS: We studied 296 patients of age 45±10 years old, of whom 28% were women, and with a BMI of 30.3±5.3kg/m2. Overall, 245 had OSA and 51 were healthy controls. After controlling for confounding variables higher ΔHR but not HB, was associated with higher CIMT (p=0.006) and higher time spent with oxygen saturation below 90% (T90) was associated with an increase in carotid atheroma plaques (p=0.032). When stratifying OSA based on HB tertiles, we observed that within tertile 2 of HB, an increase in ΔHR was associated with larger CIMT (p=0.017). CONCLUSION: A higher ΔHR is associated with an increase in CIMT among adult patients with OSA. This study suggests that ΔHR could be a biomarker of risk for CVD in patients with OSA.
RESUMO
INTRODUCTION: The co-existence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA), or the overlap syndrome, is common and associated with a distinct pattern of nocturnal hypoxemia and worse clinical outcomes than either disease alone. Consequently, identifying who and how to treat these patients is essential. AREAS COVERED: Treatment is recommended in all patients with OSA and symptoms or systemic hypertension, but determining symptoms attributable to OSA can be challenging in patients with COPD. Treatment should be considered in asymptomatic patients with moderate to severe OSA and COPD with pulmonary hypertension and comorbid cardiovascular and cerebrovascular disease, especially if marked hypoxic burden. CPAP is effective, but in patients with the overlap syndrome and daytime hypercapnia, high-intensity noninvasive ventilation aiming to lower PaCO2 may have additional benefits. Additionally, in those with severe resting daytime hypoxemia, supplemental oxygen improves survival and should be added to positive airway pressure. The role of alternative non-positive airway pressure therapies in the overlap syndrome needs further study. EXPERT OPINION: Both COPD and OSA are heterogeneous disorders with a wide range of disease severity and further research is needed to better characterize and prognosticate patients with the overlap syndrome to personalize treatment.

We examined the relationship between subjective and objective sleep outcomes and loneliness in older women at risk for Alzheimer's disease (AD). Our sample consisted of 39 participants (aged 65+) with mild cognitive deficits who completed the UCLA Loneliness Scale, the Pittsburgh Sleep Quality Index (PSQI), and an at home sleep test, to determine presence of obstructive sleep apnea. Based on sleep quality scores, individuals categorized as "poor sleepers" had significantly higher loneliness scores than "good sleepers." However, total loneliness scores did not significantly differ between groups with or without sleep apnea. We found that higher loneliness was significantly associated to lower habitual sleep efficiency and sleep duration and was also influenced by use of sleep medication. Our findings suggest that increased loneliness relates to worse subjective sleep quality, but not to sleep apnea. These findings suggest that combined interventions targeting loneliness and sleep quality may be important for older women.
RESUMO
Study Objectives: The Sleep Program at the VA San Diego Healthcare System (VASDHS) started a patient database over twenty years ago for its home sleep apnea testing (HSAT) program. An analysis of ten years of diagnostic HSAT data was reported on over 12 500 patients in 2014. Over this time period, severe obstructive sleep apnea (OSA) decreased in frequency. In contrast, mild OSA increased in frequency and was the most frequently reported severity in our analysis. In more recent times, the 2021 continuous positive airway pressure (CPAP) crisis created difficulties in dispersing CPAP therapies to individuals including Veterans with OSA, prompting our group to reexamine the HSAT database. Methods: A retrospective review was performed of the local clinical database of HSAT diagnostic testing of 8,928 sleep studies from 2018 to 2022. Results: The overall mean apnea-hypopnea index (AHI) decreased from 40.4/hour (2004) to 24.3/hour (2022) (pâ <â .001). The two time periods were examined separately. For 2004-2013, it was found that the mean AHI in 2004 was not significantly different from the mean AHI in 2005, 2006, or 2007 but was significantly different from the mean AHI in each year from 2008 (mean AHIâ =â 30.7/h) to 2013 (mean AHIâ =â 26.1/hour). For 2019-2022, the mean AHI did not significantly differ between the 4 years. Conclusions: These findings have implications for OSA therapies. Additionally, the high prevalence of mild sleep apnea, which is typically associated with lesser adherence to PAP therapy, further highlights the importance of non-PAP alternatives to improve treatment effectiveness.
RESUMO
Background: A lack of high-quality provider education hinders the delivery of standard-of-care delirium detection and prevention practices in the intensive care unit (ICU). To fill this gap, we developed and validated an e-learning ICU Delirium Playbook consisting of eight videos and a 44-question knowledge assessment quiz. Given the increasing Spanish-speaking population worldwide, we translated and cross-culturally adapted the playbook from English into Spanish. Objective: To translate and culturally adapt the ICU Delirium Playbook into Spanish, the second most common native language worldwide. Methods: The translation and cross-cultural adaptation process included double forward and back translations and harmonization by a 14-person interdisciplinary team of ICU nurses and physicians, delirium experts, methodologists, medical interpreters, and bilingual professionals representing many Spanish-speaking global regions. After a preeducation quiz, a nurse focus group completed the playbook videos and posteducation quiz, followed by a semistructured interview. Results: The ICU Delirium Playbook: Spanish Version maintained conceptual equivalence to the English version. Focus group participants posted mean (standard deviation) pre- and post-playbook scores of 63% (10%) and 78% (12%), with a 15% (11%) pre-post improvement (P = 0.01). Participants reported improved perceived competency in performing the Confusion Assessment Method for the ICU and provided positive feedback regarding the playbook. Conclusion: After translation and cultural adaptation, the ICU Delirium Playbook: Spanish Version yielded significant knowledge assessment improvements and positive feedback. The Spanish playbook is now available for public dissemination.
RESUMO
The prevalence of "long COVID" is just one of the conundrums highlighting how little we know about the lung's response to viral infection, particularly to syndromecoronavirus-2 (SARS-CoV-2), for which the lung is the point of entry. We used an in vitro human lung system to enable a prospective, unbiased, sequential single-cell level analysis of pulmonary cell responses to infection by multiple SARS-CoV-2 strains. Starting with human induced pluripotent stem cells and emulating lung organogenesis, we generated and infected three-dimensional, multi-cell-type-containing lung organoids (LOs) and gained several unexpected insights. First, SARS-CoV-2 tropism is much broader than previously believed: Many lung cell types are infectable, if not through a canonical receptor-mediated route (e.g., via Angiotensin-converting encyme 2(ACE2)) then via a noncanonical "backdoor" route (via macropinocytosis, a form of endocytosis). Food and Drug Administration (FDA)-approved endocytosis blockers can abrogate such entry, suggesting adjunctive therapies. Regardless of the route of entry, the virus triggers a lung-autonomous, pulmonary epithelial cell-intrinsic, innate immune response involving interferons and cytokine/chemokine production in the absence of hematopoietic derivatives. The virus can spread rapidly throughout human LOs resulting in mitochondrial apoptosis mediated by the prosurvival protein Bcl-xL. This host cytopathic response to the virus may help explain persistent inflammatory signatures in a dysfunctional pulmonary environment of long COVID. The host response to the virus is, in significant part, dependent on pulmonary Surfactant Protein-B, which plays an unanticipated role in signal transduction, viral resistance, dampening of systemic inflammatory cytokine production, and minimizing apoptosis. Exogenous surfactant, in fact, can be broadly therapeutic.

Obstructive sleep apnea (OSA) is strongly associated with obesity. While the relationship between weight reduction and apnea-hypopnea index improvement has been documented, to our knowledge, it has not been quantified adequately. Therefore, this study aimed to quantify the relationship between weight reduction and AHI change. METHODS: A systematic literature search was performed using meta-analyses (PRISMA) guidelines for studies reporting AHI and weight loss in people with obesity/overweight and OSA between 2000 and 2023. A linear and quadratic model (weighted by treatment arm sample size) predicted percent change from baseline AHI against mean percent change from baseline weight. The quadratic term was statistically significant (P < 0.05), so the quadratic model (with 95 % prediction interval) was used. RESULTS: The literature search identified 27 studies/32 treatment arms: 15 using bariatric surgery and lifestyle intervention each and 2 using pharmacological interventions. Included studies were ≥3 months with weight intervention and participants had AHI ≥15/h. Weight reduction in people with OSA and obesity was associated with improvements in the severity of OSA. BMI reduction of 20 % was associated with AHI reduction of 57 %, while further weight reduction beyond 20 % in BMI was associated with a smaller effect on AHI. As the prediction intervals are relatively wide, a precise relationship could not be conclusively established. CONCLUSION: The degree of AHI index improvement was associated with the magnitude of weight reduction. The model suggests that with progress in weight reduction beyond 20 %, the incremental decrease in BMI appeared to translate to a smaller additional effect on AHI.

ABSTRACT: BACKGROUND: Hourly neurological examinations (neuro exam) have been widely used to monitor for a decline in neurological status, allowing for timely intervention. There are, however, limited data behind this common practice. The objective of this study was to identify how frequently neurological decline occurred across various diagnoses and whether that decline (1) was identified by a scheduled neurocheck and (2) altered management. METHODS: A cross-sectional survey was performed in a neurological intensive care unit at a tertiary care academic medical center. Clinical neuroscience nurses caring for patients with hourly neurological assessments completed a brief survey at 12-hour shift completion. RESULTS: Data were collected from 212 nurse's shifts. Neurological changes were identified by nurses in 14% (n = 30) of shifts. The neurological change was identified during a scheduled neurocheck 67% of the time, with the detection of changes more likely to occur during a scheduled neuro exam than at other times ( P < .05). There was no change to the care plan in 55% of the cases of neurological decline. Patients with subarachnoid hemorrhage were more likely to have a decline detected. CONCLUSION: Findings suggest that many patients undergo hourly neurological exams without ever identifying a neurological deterioration. In many instances of neurodeterioration, there was no change to the treatment plan pursued. Primary diagnoses and neurological changes may not be entirely independent, and therefore, hourly neuro exams may have greater yield in some diagnoses than others. Replication is warranted with a larger sample to evaluate the risks and benefits of neuroassessments.

BACKGROUND: Obstructive sleep apnea is characterized by disordered breathing during sleep and is associated with major cardiovascular complications; excess adiposity is an etiologic risk factor. Tirzepatide may be a potential treatment. METHODS: We conducted two phase 3, double-blind, randomized, controlled trials involving adults with moderate-to-severe obstructive sleep apnea and obesity. Participants who were not receiving treatment with positive airway pressure (PAP) at baseline were enrolled in trial 1, and those who were receiving PAP therapy at baseline were enrolled in trial 2. The participants were assigned in a 1:1 ratio to receive either the maximum tolerated dose of tirzepatide (10 mg or 15 mg) or placebo for 52 weeks. The primary end point was the change in the apnea-hypopnea index (AHI, the number of apneas and hypopneas during an hour of sleep) from baseline. Key multiplicity-controlled secondary end points included the percent change in AHI and body weight and changes in hypoxic burden, patient-reported sleep impairment and disturbance, high-sensitivity C-reactive protein (hsCRP) concentration, and systolic blood pressure. RESULTS: At baseline, the mean AHI was 51.5 events per hour in trial 1 and 49.5 events per hour in trial 2, and the mean body-mass index (BMI, the weight in kilograms divided by the square of the height in meters) was 39.1 and 38.7, respectively. In trial 1, the mean change in AHI at week 52 was -25.3 events per hour (95% confidence interval [CI], -29.3 to -21.2) with tirzepatide and -5.3 events per hour (95% CI, -9.4 to -1.1) with placebo, for an estimated treatment difference of -20.0 events per hour (95% CI, -25.8 to -14.2) (P<0.001). In trial 2, the mean change in AHI at week 52 was -29.3 events per hour (95% CI, -33.2 to -25.4) with tirzepatide and -5.5 events per hour (95% CI, -9.9 to -1.2) with placebo, for an estimated treatment difference of -23.8 events per hour (95% CI, -29.6 to -17.9) (P<0.001). Significant improvements in the measurements for all prespecified key secondary end points were observed with tirzepatide as compared with placebo. The most frequently reported adverse events with tirzepatide were gastrointestinal in nature and mostly mild to moderate in severity. CONCLUSIONS: Among persons with moderate-to-severe obstructive sleep apnea and obesity, tirzepatide reduced the AHI, body weight, hypoxic burden, hsCRP concentration, and systolic blood pressure and improved sleep-related patient-reported outcomes.

RESUMO
Goal: Auscultation for neonates is a simple and non-invasive method of diagnosing cardiovascular and respiratory disease. However, obtaining high-quality chest sounds containing only heart or lung sounds is non-trivial. Hence, this study introduces a new deep-learning model named NeoSSNet and evaluates its performance in neonatal chest sound separation with previous methods. Methods: We propose a masked-based architecture similar to Conv-TasNet. The encoder and decoder consist of 1D convolution and 1D transposed convolution, while the mask generator consists of a convolution and transformer architecture. The input chest sounds were first encoded as a sequence of tokens using 1D convolution. The tokens were then passed to the mask generator to generate two masks, one for heart sounds and one for lung sounds. Each mask is then applied to the input token sequence. Lastly, the tokens are converted back to waveforms using 1D transposed convolution. Results: Our proposed model showed superior results compared to the previous methods based on objective distortion measures, ranging from a 2.01 dB improvement to a 5.06 dB improvement. The proposed model is also significantly faster than the previous methods, with at least a 17-time improvement. Conclusions: The proposed model could be a suitable preprocessing step for any health monitoring system where only the heart sound or lung sound is desired.
RESUMO
BACKGROUND: During the COVID-19 pandemic, mitigation measures were associated with a reduction in preterm birth rates; while not clearly proven, this observation has sparked significant interest. AIM: To understand the cause of this reduction by exploring the characteristics of preterm birth cohorts. MATERIAL AND METHODS: We performed a retrospective cohort study where we compared women who delivered preterm in three Melbourne maternity hospitals and conceived between November 2019 and February 2020 (mitigation measures-exposed cohort) to women who delivered preterm and conceived between November 2018 and February 2019 (non-exposed cohort). We compared maternal characteristics, pregnancy complications, antenatal interventions, intrapartum care, and indications for delivery. RESULTS: In the exposed cohort, 252/3129 women delivered preterm (8.1%), vs 298/3154 (9.4%) in the non-exposed cohort (odds ratio (OR) 0.84, 95% CI 0.70-1.00, P = 0.051). The baseline characteristic of two cohorts were comparable. Rates of spontaneous preterm labour (sPTL) without preterm pre-labour rupture of membranes (PPROM) were lower in the exposed cohort (13.1% vs 24.2%, OR 0.47, P = 0.001) while PPROM occurred more often (48.0% vs 35.6%, OR 1.67, P = 0.003). With a non-statistically significant prolongation of pregnancy in the cohort exposed to mitigation measures for both sPTL without PPROM (35.4 vs 34.9 weeks, P = 0.703) and PPROM (35.6 vs 34.9 weeks, P = 0.184). The rate of spontaneous labour after PPROM was higher in the exposed cohort compared to the non-exposed cohort (40.1% vs 24.1%, OR 2.09, P < 0.001). CONCLUSION: The reduction in preterm delivery during mitigation measures may have been driven by a reduction in spontaneous labour without PPROM, which seemed to result in more PPROM later in pregnancy.
RESUMO
INTRODUCTION: The efficacy of non-pharmacotherapeutic treatment of obstructive sleep apnea, a highly prevalent condition with serious cardiometabolic and neurocognitive health consequences, is well established. Supplementing traditional treatment strategies with medications can improve symptoms and reduce side effects. Efforts to identify medications that target the causes of sleep apnea have met with mixed success. However, this remains a worthwhile objective for researchers to pursue, given the potential benefit pharmacotherapy could bring to those patients who reject or struggle to adhere to existing treatments. AREAS COVERED: This article presents the case for obstructive sleep apnea pharmacotherapy including drugs that reduce the occurrence of apnea events, such as weight loss agents, ventilation activators and muscle and nervous system stimulants, drugs that alleviate symptoms, such as wake-promoting agents for excessive daytime sleepiness, and drugs that improve adherence to existing treatments, such as hypnotics. Literature was accessed from PubMed between 1 March 2024 and 18 April 2024. EXPERT OPINION: Exciting recent advances in both our understanding of obstructive sleep apnea pathology and in the techniques used to identify therapeutic agents and their targets combine to embolden a positive outlook for the expanded use of drugs in tackling this consequential disease.
