Introduction: Little is known about the impact of spousal involvement on continuous positive airway pressure (CPAP) adherence. The aim of this study was to determine whether spouse involvement affects adherence with CPAP therapy, and how this association varies with gender. Methods: 194 subjects recruited from Apnea Positive Pressure Long Term Efficacy Study (APPLES) completed the Dyadic Adjustment Scale (DAS). The majority of participants were Caucasian (83%), and males (73%), with mean age of 56 years, mean BMI of 31 kg/m2. & 62% had severe OSA. The DAS is a validated 32-item self-report instrument measuring dyadic consensus, satisfaction, cohesion, and affectional expression. A high score in the DAS is indicative of a person’s adjustment to the marriage. Additionally, questions related to spouse involvement with general health and CPAP use were asked. CPAP use was downloaded from the device and self-report, and compliance was defined as usage > 4 h per night. Results: There were no significant differences in overall marital quality between the compliant and noncompliant subjects. However, level of spousal involvement was associated with increased CPAP adherence at 6 months (p=0.01). After stratifying for gender these results were significant only among males (p=0.03). Three years after completing APPLES, level of spousal involvement was not associated with CPAP compliance even after gender stratification. Conclusion: Spousal involvement is important in determining CPAP compliance in males in the 1st 6 months after initiation of therapy but is not predictive of longer-term adherence. Involvement of the spouse should be considered an integral part of CPAP initiation procedures. Support: HL068060

BACKGROUND Inhalation therapy has proven to be the best way to control the asthma and chronic obstructive pulmonary disease symptoms. The most commonly used delivery system to control these symptoms is the metered-dose inhaler. The primary goal of this study is to demonstrate an association between incorrect inhaler use and patient age. METHODS This is a cross-sectional study, performed at Centro Médico Naval “Cirujano Mayor Santiago Távara”, in Callao, Peru, in 2014. Patients older than 18 years that used metered-dose inhalers were included. We used film recordings of patients using a metered-dose inhaler and compared their technique with the recommendations on the guidelines on the correct use of inhalers of the Spanish Society of Pneumology and Thoracic Surgery (SEPAR). The main variables measured were age and incorrect inhaler use. The results were analyzed with the Chi squared test for bivariate analysis, and for multivariate analysis we used the Poisson regression model with robust variance. RESULTS We included 378 patients in the analysis; 167 were older than 60 years. An association was found between incorrect inhalator technique and age (p=0.014) (PR 1.19 95% CI 1.03 to 1.37). The highest prevalence of incorrect technique was found in the young adult population (88%). There was no association between the incorrect technique and the person who taught it (p=0.114). Finally, this study showed that 81.2% of the study population presented an incorrect inhalation technique. CONCLUSIONS The percentage of incorrect inhaler use, in the general population is high. Even if we found no association between an incorrect technique and the person who taught it; still, there is a high percentage of errors and it was even demonstrated that being instructed by a pulmonologist does not guarantee a correct performance of metered-dose inhaler inhalations. / INTRODUCCIÓN La terapia inhalatoria ha demostrado ser la más rápida y eficaz para el control del asma y la enfermedad pulmonar obstructiva crónica. El inhalador de dosis medida es el más usado por la población. El objetivo de este estudio es evidenciar la asociación entre la técnica inhalatoria incorrecta y la edad. MÉTODOS Estudio observacional, analítico, de corte transversal realizado en Perú durante 2014. Se incluyeron pacientes desde los 18 años que utilizaran inhalador de dosis medida. Se utilizó una lista de verificación de pasos establecidos por la Sociedad Española de Neumología y Cirugía Torácica y filmaciones para evaluar la técnica inhalatoria de los pacientes. Las variables principales fueron la edad y la mala técnica inhalatoria práctica. Para el análisis bivariado se utilizó la prueba Chi cuadrado y para el análisis multivariado regresión de Poisson con varianza robusta. RESULTADOS Se incluyeron 378 pacientes; 167 fueron mayores de 60 años. El estudio reveló que el 81,2% de la población presentó una incorrecta técnica inhalatoria. Se encontró asociación entre la edad y la técnica inhalatoria incorrecta (p=0,014) (PR 1,19 con IC 95% 1,03-1,37). El grupo etario con mayor frecuencia de técnica incorrecta fue el de adultos jóvenes (88%). CONCLUSIONES La frecuencia de uso incorrecto del inhalador en la población es alta y esta característica predomina en el grupo de adultos jóvenes. A pesar de no haber asociación entre la persona que enseña la técnica inhalatoria y el desempeño de la misma, se demostró que existe alta frecuencia de errores, incluso en aquellos pacientes instruidos por un médico especialista.

Background: Obstructive sleep apnea has become recognized as one of the most common, under-diagnosed chronic diseases. Recently studies have shown increased numbers among the pediatric and adolescent population. OSA in children is associated with behavioral problems, poor school achievements, and in severe cases, pulmonary hypertension. OSA is often the Achilles heel of pediatric sedation and analgesic programs; during sedation, children with OSA have an increased vulnerability of their airway undergoing pharyngeal collapse and of having upper airway obstruction. Consequently, pediatric dentists who practice sedation dentistry should exercise extra precautions when treating patients with risk of sleep apnea. Currently there is no screening tool used in pediatric dentistry for diagnosing OSA during the pre-operative appointment or consultation for patients undergoing minimal and moderate oral conscious sedation. The purpose of this study was to develop and test a concise and easy-to-use questionnaire as a screening tool to aid in the diagnosis of OSA in pediatric patients. Materials and Methods: A retrospective chart review of 180 patients under the age of 18, who completed a polysomnogram at the VCU Center for Sleep Medicine between February 2011 and February 2013. A validated adult questionnaire, STOPBANG, was modified using more typical pediatric risk factors for OSA: presence of snoring (S), tonsillar hypertrophy (T1), tiredness; pESS>10 (T2), observed obstruction (O), neuroPsych-behavioral symptoms such as ADHD or daytime irritability (P), BMI percentile for age (B), age at diagnostic screening (A), presence of neuromuscular disorder (N), and presence of genetic/congenital disorder (G). A positive scoring from these variables was measured against the standard OSA measure, Apnea-Hypopnea Index. A multiple logistic regression analysis tested for relationships. Results: There was a statistically significant relationship P= .0007 for the S(T1)OPBANG scale, with a minimum of 4 variables needed to have a sensitivity of 57% and a specificity of 78%. There was also a statistically significant relationship P= .0040 for the S(T2)OPBANG, the cutoff>5 yielding sensitivity=36%, and specificity=90%. Only obstruction, BMI, and age showed a strong significant relationship to OSA. The presence of an obstruction was positively related to apnea (P = 0.0010). Most of the other components had an odds-ratio larger than one (indicating a nominally positive relationship). Conclusions: While both STOPBANG screening tools showed a statistically significant relationship, only obstruction, BMI, and age showed a predictive relationship to OSA. Consequently, consideration of other risk factors may be beneficial for future studies.

Nonalcoholic fatty liver disease (NAFLD) afflicts approximately a quarter of the world’s general population and more than half of the world’s obese population. The disease is characterized by a spectrum of liver pathologies, ranging from simple steatosis or the accumulation of fat within hepatic tissue to steatohepatitis comprised of inflammation and fibrosis, also known as NASH. Simple steatosis is relatively asymptomatic and is considered benign, but NASH poses great risk for advanced forms of liver disease, such as cirrhosis and hepatocellular cancer. Obstructive sleep apnea(OSA) is a respiratory disorder involving the recurrent collapse of the upper airway during sleep. Consequently, the patient experiences constant arousals due to constant blockage followed reopening of the airway. Aside from poor quality and disruption of sleep, chronic intermittent hypoxia (CIH) is also present during OSA. The presence of CIH leaves many vital organs deprived of adequate oxygen to carry out normal physiological function. In response to this hypoxic state, the body upregulates many transcription factors, many of which control inflammatory processes. In recent studies, chronic and recurrent hypoxia generated from OSA has been implicated in the onset and progression of NAFLD. The pathogenesis of NAFLD is believed to be associated with metabolic imbalances, mainly obesity and insulin resistance, both of which also overlap with OSA. These conditions are the main factors in predisposing a patient suffering from OSA to the effects of CIH. Multiple lines of evidence suggest that CIH may accelerate the development of NAFLD through 1) Lipolysis of hepatic adipose tissue and increased hepatic free fatty acids; 2) Upregulation of lipid biosynthetic through CIH; 3) Upregulation of hypoxia-inducible factor 1-alpha by CIH inducing liver inflammation and fibrosis. The primary focus of this thesis will attempt to determine a possible link between OSA and NAFLD. Through citation of prior scientific studies, it will formulate the theory of OSA as a predisposing factor in the heightened risk of NAFLD pathogenesis and development to more severe, terminal stages. Primarily, the review of literature will highlight the metabolic imbalances of obesity and insulin resistance and how each is related to OSA and NAFLD. Ultimately, deposition of fat and inflammation triggered through various chemical factors connected to OSA will depict both the generation and progression of NAFLD.

Chronic obstructive pulmonary disease (COPD) is characterized by periodic episodes of worsening symptom (e.g., shortness of breath, irregular breathing, and worse coughing with increased phlegm production), also called pulmonary exacerbations. Inflammation is an important cause of reduced lung function as inflammation contributes to airflow obstruction in the small airways and lung parenchyma. Even in individuals with mild COPD, inflammation reduces lung function, accelerates decline in lung function overtime, and increases the risk for respiratory exacerbations. Agents that reduce systemic inflammation are hypothesized to decrease the inflammation in the lungs, resulting in improvements in lung function and a decrease in exacerbation frequency. We hypothesize that antidepressants have a beneficial effect on lung function. In addition to having anti-inflammatory properties, antidepressants act upon serotonin, which is integral in central breathing control. The combination of the anti-inflammatory and serotonergic effects may provide users of selective serotonin reuptake inhibitors with a lung function benefit while avoiding the side effects of steroids. This dissertation assesses whether selective serotonin reuptake inhibitors increase concurrent lung function and reduce the risk for respiratory exacerbations. It consists of three parts: a systematic literature review and two analytic papers using large prospective databases. The systematic review of the literature identified limitations concerning the effect of selective serotonin reuptake inhibitors on lung function. Overall, the analytic papers found no support for a beneficial association between selective serotonin reuptake inhibitors and spirometry, dyspnea or pulmonary exacerbations; indeed the association was in the opposite direction as hypothesized. In addition, there was no support for meaningful mediation by inflammatory markers. Further research is needed to determine if selective serotonin reuptake inhibitors have a harmful effect on lung function and pulmonary exacerbations.
