Sleep Disturbance and Depression as Barriers to Adherence

Examining the Longitudinal Effects of Insomnia on Depression and Medication Adherence in People Living with HIV

OBJECTIVE

The management of HIV has shifted from a focus solely on the disease to a broader perspective encompassing co-occurring medical conditions and quality of life. Mental health concerns such as depression and sleep disturbances, particularly insomnia, are often overlooked in HIV care. The aim of the study was to investigate the longitudinal impact of insomnia on depression and medication adherence among (PLWH).

METHODS

This study, conducted in an urban HIV clinic, involved active patients and assessed depression, insomnia, and medication adherence at baseline, 3-month, and 6-month intervals. Hierarchical linear models were employed to analyze the fixed and random effects of time, within-person and between-person insomnia on depression, as well as the effects of time, within-person and between-person depression on ART adherence.

RESULTS

Within-person effects revealed that each one unit increase in the Insomnia Severity Index (ISI) was associated with a b = 0.267-point rise in Patient Health Questionnaire-9 (PHQ-9) scores (p < .001). Between-person effects revealed that each one-point increase in an individual's average ISI score was associated with a 0.476-point elevation in their PHQ-9 scores (p < .001). The between-person effects of depression on medication adherence indicated significance, with each point increase in an individual's average PHQ-9 score being linked to a 0.36% decrease in adherence (p = .012).

CONCLUSION

The study underscores the potential impact of insomnia on mental health and treatment adherence in people living with HIV (PLWH). This study emphasizes the necessity of comprehensive care models considering the interplay between sleep quality, mental health, and medication adherence for PLWH.

The screening and management of sleep disturbances in people living with HIV: Delphi consensus

Sleep disturbances in people living with HIV (PLHIV) are frequent but their management remains insufficient. In the absence of specific recommendations, a DELPHI consensus research project was conducted in France to establish best practice. A multidisciplinary Steering Committee (STC) undertook a literature review and used it with clinical expertise to create statements that were voted on. Two profiles of healthcare professionals with significant experience in monitoring PLHIV were selected for the voting: physicians and nurses/psychologists. Votes were collected electronically, independently, and anonymously. The STC created 27 statements covering six areas: Screening of sleep disturbances, Investigation, First-line management, Referral to a specialist, Antiretroviral treatment (ARV), and Prevention. Two rounds of votes included 42 physicians and 32 nurses/psychologists. Consensus was reached for 24 out of 27 statements (89%) including: to assess quantity and quality of sleep among PLHIV at least annually, ideally using a common methodology within the medical department; to consider the temporary addition of a hypnotic treatment in cases of acute insomnia not improved by the rules of sleep hygiene, with full awareness of potential drug-drug interactions and risk of dependence; to correct ferritinaemia if <100 ng/mL before referral to a specialist when restless legs syndrome is suspected; to consider changing the time of ARV administration or an ARV switch within the same class when sleep disturbances are caused by an ARV. This DELPHI Consensus provides best practice for screening and managing sleep disturbances in PLHIV and optimising their quality of life.

The Concurrent and Longitudinal Relationship between Perinatal Sleep Difficulties and Depression in a Large Sample of High-Risk Women in South Africa

INTRODUCTION

Perinatal depression and sleep difficulties are common among studies conducted in high income countries (HIC). This study examines the relationship between sleep difficulties and depression during the perinatal period and over an eight-year follow-up period in South Africa, a middle income country.

METHOD

A population cohort of 1238 pregnant women (mean age = 26.33) in 24 township neighborhoods in South Africa were recruited and reassessed six times over the next 8 years post birth with follow-up rates of 96-83%. The relationship between maternal depressed mood and sleep difficulties was examined over time, as well as the relationship of sleep with other socioeconomic, environmental, and psychiatric risk factors.

RESULTS

Thirty-five percent of the women reported sleep difficulties during the perinatal period; whereas only 8% reported sleep difficulties at 8-year follow-up. Perinatal sleep difficulties were associated with lower income, lower educational attainment, less access to electricity, more food insecurity, higher rates of interpersonal violence and HIV, alcohol consumption, and depressed mood at 8 years. However, the severity of depressed mood was the strongest predictor of sleep problems longitudinally and cross-sectionally, after accounting for all other risk factors.

CONCLUSIONS

We found that the severity of depressed mood is highly associated with sleep difficulties from pregnancy to 8 years post-birth and in a linear relationship, so that higher depressed mood is associated with more sleep problems.

Psychological Mechanisms of Internalized HIV Stigma Affect Sleep Impairment among People Living with HIV in China: A follow-up Study

Prior studies have demonstrated that HIV-related stigma (e.g., internalized HIV stigma) is detrimental to the physical and mental health (e.g., sleep impairment and depressive symptoms) of people living with HIV (PLWH). However, follow-up data are limited regarding the longitudinal relationships between internalized HIV stigma, future orientation, self-esteem, depressive symptoms, and sleep impairment. The present study attempted to examine a mediation model involving these variables among Chinese PLWH. A two-wave follow-up design (6 months intervals) was employed in a final sample of 1,140 Chinese PLWH (Mage = 41.63, SD = 9.29, age range: 21-67 years; 64.6% men). Participants completed Internalized HIV Stigma Scale, Optimism About the Future Scale, Rosenberg Self-Esteem Scale, Center of Epidemiological Studies Depression Scale, and an adapted version of Pittsburgh Sleep Quality Index. Results revealed that internalized HIV stigma at baseline had a significant direct relationship with sleep impairment over time, and a significant indirect relationship with increased sleep impairment over time via future orientation and depressive symptoms. Furthermore, the linkage between internalized HIV stigma and sleep impairment was serially mediated via self-esteem and depressive symptoms. This study highlights the deleterious effects of internalized HIV stigma on the physical and psychological health of PLWH. The findings suggest that interventions targeting internalized HIV stigma and related factors such as future orientation, self-esteem, and depressive symptoms may facilitate improvements in sleep quality and overall well-being among PLWH.

An observational, patient-reported outcome study of sleep quality and depression among individuals with overactive bladder syndrome

INTRODUCTION

Overactive bladder (OAB) can adversely affect health-related quality-of-life (HRQoL) and adherence to treatments; however, the extent of their association is unknown. This study sought to characterize Sleep Disturbance, Depression, Fatigue, and patient-reported medication adherence among adults with OAB in the United States. MATERIALS AND METHODS: In this descriptive, observational study, patients completed patient-reported outcome (PRO) measures of urinary symptoms, anxiety, depression, fatigue, sleep quality, and medication adherence. PRO scores were compared across age, sex, body mass index, and sleep and antidepressant medication-taking subgroups. Exploratory analyses compared PRO scores between groups and estimated the effect size of differences.

RESULTS

Of 1013 patients contacted, 159 completed the assessments (female: 67.3%; ≥65 years of age: 53.5%; most severe OAB symptom: nocturia). Scale scores for Sleep Disturbance, Fatigue, and Depression were consistent with US population norms. No correlations of moderate or greater magnitude were observed between the severity of lower urinary tract symptoms and Sleep Disturbance, Fatigue, or Depression. When comparing individuals receiving antidepressants with those who were not, almost all outcomes including urinary symptoms, anxiety, and depression were significantly worse. Patients taking antidepressants also had poorer adherence to their OAB medications.

CONCLUSION

In this cohort of individuals with OAB, Sleep Disturbance, Fatigue, and Depression scores were in line with general population reference values; however, among the subgroups analyzed, patients on antidepressants had worse HRQoL and more substantial impacts on medication adherence, highlighting the importance of the assessment and management of depression in this population.

Sleep quality and associated factors among adult people living with HIV on follow-up at Dessie Town Governmental Health Facilities Antiretroviral Therapy Clinics, Northeast, Ethiopia, 2020, a multicenter cross-sectional study

BACKGROUND

Poor sleep quality is an important health problem in people living with HIV. The exact cause of sleep disturbance is not well known, but it may relate to HIV itself, antiretroviral drug side effects, and other HIV-related disorders. As a result, the purpose of this study was to assess sleep quality and associated factors among adult HIV patients on follow-up at Dessie Town governmental health facilities' antiretroviral therapy clinics in Northeast Ethiopia in 2020.

METHODS

A multi-center cross-sectional study was conducted among 419 adult people living with HIV/AIDS from February 1/2020 to April 22/2020 in Dessie Town governmental antiretroviral therapy clinics. A systematic random sampling method was used to select the study participants. An interviewer-administered method of data collection with a chart review was used. The Pittsburgh Sleep Quality Index was used to evaluate sleep disruption. A binary logistic regression was conducted to see the relationship between a dependent variable and independent variables. Variables with a p-value of < 0.05 and a 95% confidence interval were used to declare an association between factors and a dependent variable.

RESULTS

A total of 419 study participants were enrolled in this study, with a response rate of 100%. The mean age of the study participants was 36 ± 6.5 SD years and 63.7% of the participants were female. The prevalence of poor sleep quality was found to be 36% (95% CI, 31-41%). Being female (AOR = 3.45, 95% CI: 1.52-7.79), viral loads 1000 copies/ml (AOR = 6.88, 95% CI: 2.79-16.9), CD4 cell count 200 cells/mm3 (AOR = 6.85, 95% CI: 2.42-19.39), WHO stage II and III (AOR = 4.29, 95% CI: 1.05-17.53), having anxiety (AOR = 10, 95% CI: 4.21-23.9.

CONCLUSION

The findings of this study showed that more than one-third of the study participants had poor-quality sleep at the Dessie Town Health Facility ART clinic. Being female, low CD4 cell counts, viral load ≥1000 copies/ml, WHO stage II and III, depression, anxiety, sleeping in a communal bedroom, and living alone were predictors of poor sleep quality.

Biomarker associations with insomnia and secondary sleep outcomes in persons with and without HIV in the POPPY-Sleep substudy: a cohort study

STUDY OBJECTIVES

We investigated associations between inflammatory profiles/clusters and sleep measures in people living with HIV and demographically-/lifestyle-similar HIV-negative controls in the Pharmacokinetic and clinical Observations in PeoPle over fiftY (POPPY)-Sleep substudy.

METHODS

Primary outcome was insomnia (Insomnia Severity Index [ISI]>15). Secondary sleep outcomes included 7-day actigraphy (e.g. mean/standard deviation of sleep duration/efficiency), overnight oximetry (e.g. oxygen desaturation index [ODI]) and patient-reported measures (Patient-Reported Outcomes Measurement Information System (PROMIS) sleep questionnaires). Participants were grouped using Principal Component Analysis of 31 biomarkers across several inflammatory pathways followed by cluster analysis. Between-cluster differences in baseline characteristics and sleep outcomes were assessed using Kruskal-Wallis/logistic regression/Chi-squared/Fisher's exact tests.

RESULTS

Of the 465 participants included (74% people with HIV, median [interquartile range] age 54 [50-60] years), only 18% had insomnia and secondary sleep outcomes suggested generally good sleep (e.g. ODI 3.1/hr [1.5-6.4]). Three clusters with distinct inflammatory profiles were identified: "gut/immune activation" (n = 47), "neurovascular" (n = 209), and "reference" (relatively lower inflammation; n = 209). The "neurovascular" cluster included higher proportions of people with HIV, obesity (BMI>30 kg/m2), and previous cardiovascular disease, mental health disorder, and arthritis of knee/hip relative to the other two clusters. No clinically relevant between-cluster differences were observed in proportions with insomnia (17%, 18%, 20%) before (p = .76) or after (p = .75) adjustment for potential confounders. Few associations were observed among actigraphy, oximetry, and PROMIS measures.

CONCLUSIONS

Although associations could exist with other sleep measures or biomarker types not assessed, our findings do not support a strong association between sleep and inflammation in people with HIV.

Interpersonal violence and other social-structural barriers associated with needing HIV treatment support for women living with HIV

Women living with HIV (WLWH), experience disproportionate rates of violence, along with suboptimal HIV health outcomes, despite recent advancements in HIV treatment, known as antiretroviral therapy (ART). The objectives of this study were to: (a) describe different types of support needed to take ART and (b) investigate the social and structural correlates associated with needing support for ART adherence among WLWH. Data are drawn from Sexual health and HIV/AIDS: Women's Longitudinal Needs Assessment, a community-based open research cohort with cisgender and transgender WLWH, aged 14+ who live or access HIV services in Metro Vancouver, Canada (2014-present). Baseline and semi-annual questionnaires are administered by community interviewers alongside a clinical visit with a sexual health research nurse. Bivariate and multivariable logistic regression using generalized estimating equations and an exchangeable working correlation matrix was used to model factors associated with needing supports for ART adherence. Among 276 WLWH, 51% (n = 142) reported needing support for ART adherence; 95% of participants reported lifetime gender-based violence and identified many interpersonal, structural, community, and clinical supports that would facilitate and support ART adherence. In multivariable logistic regression, participants who were Indigenous (adjusted odds ratio [AOR]: 1.70, 95% confidence intervals [CI]: 1.07-2.72), or otherwise racialized (AOR: 2.36, 95% CI : 1.09-5.12) versus white, experienced recent gender-based physical violence (AOR : 1.54, 95% CI : 1.03-2.31), lifetime post-traumatic stress disorder (AOR : 1.97, 95% CI : 1.22-3.18), and recent illicit drug use (AOR : 2.15, 95% CI : 1.43-3.22), had increased odds of needing support for ART adherence. This research suggests a need for trauma-informed, culturally safe and culturally responsive practice and services for WLWH along the HIV care continuum to support ART adherence. All services should be developed by, with, and for WLWH and tailored according to gender identity, taking into account history, culture, and trauma, including the negative impacts of settler colonialism for Indigenous people.

Recruitment and Retention of Women Living With HIV for Clinical Research: A Review

Women are underrepresented in HIV clinical research. However, there has not been a review on how to effectively recruit and retain women living with HIV in research. The purpose of this review is to describe recruitment and retention methods and factors associated with research participation among women living with HIV in the U.S. We searched PubMed, CINAHL, and Google and synthesized studies using thematic analysis. The most common method of recruiting women with HIV into research was through community-based HIV clinics, and the greatest yield was from word of mouth and a university HIV research center. Attrition may occur early and can be addressed by focusing on retention as early as study planning. Barriers to research participation for women can be addressed through retention methods discussed. We conclude that building relationships with community members and women living with HIV, being flexible, and implementing many methods is important for recruitment and retention.

Considering the Role of Adherence in New and Emerging Sleep Treatments

There are several novel and emerging treatments for obstructive sleep apnea (OSA), including new devices and pharmacotherapies. Long-term efficacy and adherence data for these interventions in the sleep context are lacking. Future studies exploring the long-term adherence and efficacy in novel and emerging treatments of OSA are required to fully understand the place of these treatments in treatment hierarchies. Such research also should aim to evaluate the use of these novel therapies in real-world clinical settings, because many of the studies performed to date have been done under closely monitored research populations and relatively small sample sizes.

Application of the Chinese Version of the Pittsburgh Sleep Quality Index in People Living With HIV: Preliminary Reliability and Validity

Background: The Pittsburgh Sleep Quality Index (PSQI) has been a widely used instrument measuring sleep quality among people living with HIV (PLWH) in China while its psychometric properties have yet to be examined in this population. We aimed to assess the reliability and validity of the Chinese version of PSQI in PLWH and identify factors associated with sleep quality. Methods: This study was based on a longitudinal study of newly diagnosed PLWH, among whom the PSQI was used to measure sleep quality 5 years after HIV diagnosis (n = 386). To evaluate internal consistency, Cronbach's alpha and corrected item-total correlation were calculated. To assess construct validity, Pearson's correlation coefficients were calculated between PSQI scores and depression, anxiety, stress, and health-related quality of life (HRQoL). Known group validity was evaluated by comparing PSQI scores between participants with probable depression and those without. Binary logistic regression was conducted to identify factors associated with sleep disturbances. Results: The internal consistency Cronbach's alpha for the Chinese version of PSQI in PLWH was 0.713. Construct validity was established by significant relationships between PSQI and depression, anxiety, stress, and HRQoL. The PSQI scores in participants with probable depression were significantly higher than those without, indicating good known-group validity. Sleep disturbances were associated with less income, higher CD4 counts, antiretroviral treatment (ART) initiation, exercise, depression, and higher stress levels. Conclusions: The Chinese version of PSQI is feasible for use among Chinese PLWH. Over a third of PLWH reported sleep disturbances. More attention should be given to individuals with less income and on ART. Intervention aimed at improving mental health or facilitating exercise may improve sleep quality.

The effect of daily walking exercise on sleep quality in healthy young adults

Purpose

Walking has beneficial effects on sleep quality in elderly population and patients in clinical settings. However, less is known whether walking improves sleep quality among healthy young adults. This study examined the effectiveness of a 12-week walking intervention on sleep quality among sedentary young adults.

Methods

Fifty-four healthy adults aged 19 to 36-years old participated a pedometer based aerobic walking intervention, a cross-over randomized control trial. Participants were assigned into two groups (group A and group B) randomly. The 12-week intervention was divided into three sessions equally. Sleep quality was assessed by Pittsburgh Sleep Quality Index (PSQI) before and after session 1 and session 3. Omron HJ-112 pedometer and daily walking diary facilitated the intervention process. Within group and between group comparisons were made for statistical analysis.

Results

Within group comparison by repeated measures showed that sleep duration (p < 0.01, F-test 22.79), sleep medication (p < 0.05, F-test 5.22), subjective sleep (p < 0.05, F-test 5.51) and global sleep quality (p < 0.01, F-test 12.19) were significantly improved. The comparison between intervention group and control group showed that sleep disturbance was significantly improved (p < 0.05).

Conclusion

Daily walking exercise has a significant effect on facilitating sleep quality and sleep components among young adults. Further studies are suggested to examine the impact of walking intensity on sleep quality.

Prevalence, risk factors, and trajectories of sleep disturbance in a cohort of African-American breast cancer survivors

PURPOSE

Sleep disturbance may be an overlooked modifiable risk factor for health disparities among African-American breast cancer survivors (AABCS). This study aimed to identify the prevalence of and risk factors for sleep disturbance in a cohort of AABCS.

METHODS

The study was conducted among participants in the Women's Circle of Health Follow-up Study, a longitudinal study of breast cancer in 10 counties in New Jersey. Cases were identified shortly after diagnosis by the New Jersey State Cancer Registry. Self-reported sleep disturbance (Pittsburgh Sleep Quality Index) and other factors (e.g., socioeconomic status, menopausal status) were assessed at pre-diagnosis (n = 637), 10 months post-diagnosis (n = 261), and 24 months post-diagnosis (n = 632). Clinical data were obtained via medical record abstraction, and height and weight were measured by study staff.

RESULTS

Most AABCS (57%) reported clinically significant sleep disturbance before diagnosis, and this rate remained largely unchanged at 10 months (53%) and 24 months post-diagnosis (61%). Average sleep disturbance scores indicated clinically significant disturbance at all three assessments (M range = 6.67-7.57). Most reported sleeping fewer than the recommended 7 hours per night at each assessment (range 57-65%). Risk factors for sleep disturbance were identified at each assessment, including pre-diagnosis (less education), 10 months post-diagnosis (lack of insurance, treatment with chemotherapy), and 24 months post-diagnosis (younger age, less education, lower income, obesity, and lymphedema). Treatment with endocrine therapy was a protective factor at 10 months post-diagnosis.

CONCLUSION

Most AABCS report clinically significant sleep disturbance from before diagnosis through 24 months post-diagnosis. These rates appear indicate AABCS experience significant sleep-related disparities.

A comparison of diabetes self-care behavior in people with type 2 diabetes with and without insomnia symptoms

AIMS

Individuals with type 2 diabetes (T2DM) are advised to undertake diabetes self-care behavior (DSCB) in order to avoid complications of T2DM. However, comorbidities, such as insomnia symptoms which are commonly reported in people with T2DM, may limit the ability to engage in DSCB. Insomnia and the common sequelae accompanying insomnia such as pain, depression, and anxiety may negatively influence the performance of DSCB. Therefore, this study aimed to compare the DSCB of people with T2DM with and without insomnia symptoms.

METHODS

Sixty participants with T2DM were divided into two groups based on the presence of insomnia symptoms: T2DM-only group and T2DM+ insomnia group. Insomnia symptoms were identified using the Insomnia Severity Index (ISI). DSCB was assessed using the Diabetic Care Profile (DCP). A standardized composite score was established to account for all of the DCP domains. Chi-square and independent sample t tests were used to assess between-group differences in categorical and continuous variables, respectively. Stepwise linear regression analysis used the ISI score to predict standardized DCP composite score, while controlling for covariates.

RESULTS

Significant between-group differences were found in age, symptoms of pain, depression, and anxiety. The total DCP composite score was significantly lower in the T2DM+ insomnia group compared to the T2DM-only group (- 0.30 ± 0.46 vs. 0.36 ± 0.48, respectively, p < 0.001) with large effect size (g = 1.40). Stepwise linear regression results showed that a 1-point increase in ISI score significantly predicted a .03-point decrease in standardized DCP composite score, after controlling for age, symptoms of pain, depression, and anxiety (β = - 0.03, p = 0.04).

CONCLUSIONS

The data suggest that people with T2DM and insomnia symptoms had worse scores on the majority of the DSCB domains and a worse DCP composite score compared to people with T2DM only. The data suggest a negative association between insomnia severity and DSCB among people with T2DM. Further research using a larger sample size and more rigorous research design is required to examine the causal relationship between insomnia symptoms and DSCB.

Knowledge, practice and correlates of sleep hygiene among people living with HIV/AIDS attending anti-retroviral therapy at Zewditu Memorial Hospital, Addis Ababa, Ethiopia: a cross-sectional study

Background

Sleep hygiene is a series of behavioral practices that can be performed by individuals with sleep complaints to prevent or reverse sleep difficulties. The feasibility, cost-effectiveness, absence of side effects and immediate responses to sleep problems make sleep hygiene practices more applicable than other treatment options for people living with HIV/AIDS. However, there is no evidence regarding sleep hygiene awareness and its practice in people with HIV/AIDS in Ethiopia.

Objectives

This study aimed to assess the knowledge, practice and correlates of sleep hygiene among adults attending outpatient anti-retroviral treatment at Zewditu Memorial Hospital.

Methods

This was an institutional based cross-sectional study conducted from 1st of May to 16th of June 2018 amongst people attending anti-retroviral therapy follow-up at Zewditu Memorial Hospital. Systematic random sampling technique was used to recruit a total of 396 study participants. Data were collected using interviewer-administered questionnaire. The Sleep Hygiene Index was used to measure the level of sleep hygiene of study participants. Binary logistic regression analysis was conducted to identify factors associated with sleep hygiene practice. In the multi-variable analysis, variables with P-values of less than 0.05 were considered as significant correlates of sleep hygiene practice with 95% confidence interval.

Results

The findings of this study showed that there are limitations regarding the knowledge and practice of sleep hygiene of people with HIV/AIDS in Ethiopia. None of the participants attended training regarding sleep hygiene. More than half (51.3%) had poor sleep hygiene practice. Female sex [AOR = 5.80:95% CI (3.12, 10.7)], being single [AOR =2.29:95% CI (0.13, 9.51)], depression [AOR = 2.93: 95% CI (1.73, 4.96)] and current khat use [AOR = 3.30; 95% CI (1.67, 6.50)] were identified as statistically significant correlates of poor sleep hygiene practice.

Conclusions

Knowledge regarding sleep hygiene is poor, and its practices are incorrect amongst people living with HIV/AIDS in Ethiopia. These findings demonstrate a need for professionals to play a major role in addressing this problem by integrating sleep hygiene as an added treatment modality to the HIV/AIDS care service. Designing training programs and awareness creation strategies for people with HIV/AIDS to improve their sleep hygiene practice is also highly recommended.

Associations between prescribed benzodiazepines, overdose death and buprenorphine discontinuation among people receiving buprenorphine

BACKGROUND AND AIMS

Benzodiazepines are commonly prescribed to patients with opioid use disorder receiving buprenorphine treatment, yet may increase overdose risk. However, prescribed benzodiazepines may improve retention in care by reducing buprenorphine discontinuation and thus may prevent relapse to illicit opioid use. We aimed to test the association between benzodiazepine prescription and fatal opioid overdose, non-fatal opioid overdose, all-cause mortality and buprenorphine discontinuation.

DESIGN AND SETTING

This was a retrospective cohort study using five individually linked data sets from Massachusetts, United States government agencies.

PARTICIPANTS

We studied 63 389 Massachusetts residents aged 18 years or older who received buprenorphine treatment between January 2012 and December 2015.

MEASUREMENTS

Filled benzodiazepine prescription during buprenorphine treatment was the main independent variable. The primary outcome was time to fatal opioid overdose. Secondary outcomes were time to non-fatal opioid overdose, all-cause mortality and buprenorphine discontinuation. We defined buprenorphine discontinuation as having a 30-day gap without another prescription following the end date of the previous prescription. We used Cox proportional hazards models to calculate hazards ratios that tested the association between receipt of benzodiazepines and all outcomes, restricted to periods during buprenorphine treatment.

FINDINGS

Of the 63 345 individuals who received buprenorphine, 24% filled at least one benzodiazepine prescription during buprenorphine treatment. Thirty-one per cent of the 183 deaths from opioid overdose occurred when individuals received benzodiazepines during buprenorphine treatment. Benzodiazepine receipt during buprenorphine treatment was associated with an increased risk of fatal opioid overdose adjusted hazard ratio (HR) = 2.92, 95% confidence interval (CI) = 2.10-4.06, non-fatal opioid overdose, adjusted HR = 2.05, 95% CI, 1.68-2.50, all-cause mortality, adjusted HR = 1.90, 95% CI, 1.48-2.44 and a decreased risk of buprenorphine discontinuation, adjusted HR = 0.87, 95% CI, 0.85-0.89.

CONCLUSIONS

Benzodiazepine receipt appears to be associated with both increased risk of opioid overdose and all-cause mortality and decreased risk of buprenorphine discontinuation among people receiving buprenorphine.

Changes in Sleep Quality and Associated Health Outcomes among Gay and Bisexual Men Living with HIV

Objectives/Background: Although gay, bisexual, and other men who have sex with men (GBMSM) bear a disproportionate burden of HIV in the U.S., they are underrepresented in HIV-related sleep research. This study sought to (a) investigate changes in self-reported sleep quality among a sample of GBMSM living with HIV during participation in an online sexual risk reduction intervention and (b) examine whether changes in sleep quality predicted later health outcomes.Method/Participants: Men (n = 505) completed measures of sleep quality, psychological distress, condom use self-efficacy, and antiretroviral therapy (ART) adherence. Analyses focused on data obtained from participants as part of the eligibility survey, baseline assessment, and the 9- and 12-month follow-up assessments.Results: Most participants did not report changes in their sleep quality (i.e., 50.1% maintained good sleep quality, 22.8% maintained poor sleep quality) between study screening and 9-month follow-up. Nevertheless, 17.0% indicated improved sleep quality and 10.1% indicated a negative change in sleep quality. Compared to those who maintained good sleep quality during the study, men whose sleep quality declined by 9 months reported significantly greater symptoms of depression and anxiety, as well as lower ART adherence and condom use self-efficacy at 12 months. Similarly, men who maintained poor sleep quality reported greater symptoms of depression and anxiety at 12 months. Men whose sleep quality improved reported better mental health than those with poor or worsening sleep quality.Conclusions: Findings suggest that optimizing sleep health should be prioritized in interventions aimed at improving overall well-being of GBMSM living with HIV.

Associations Among Trajectories of Sleep Disturbance, Depressive Symptomology and 24-Hour Urinary Cortisol in HIV+ Women Following a Stress Management Intervention

Objective: The burden of sleep disturbance and depressive symptomology is high for persons living with HIV and particularly so for women. While cognitive behavioral stress management (CBSM) is shown to reduce symptoms of depression and 24-hr urinary free cortisol output (CORT) in HIV+ men, less is known about the effects of CBSM on mood and concomitant sleep disturbance in HIV+ women. The study aim is to model longitudinal change in sleep disturbance, depressive symptomology, and CORT for HIV+ women exposed to a 12-week CBSM intervention or control condition. Methods: Self-reported sleep quality and depressive symptomology, along with CORT, was collected from surveys at baseline and approximately every three months thereafter for nine months from 130 HIV+ women (M_age = 38.44, SD = 7.73). The data was used to specify a parallel process latent growth model with CORT as a time-varying covariate. Results: The model showed acceptable fit. There was a linear decline in sleep disturbance (β = -0.32, p < .05) and logarithmic decline in depressive symptomology (β = -0.33, p < .05) for those receiving the intervention. Decline in sleep disturbance predicted lower CORT at nine months. Furthermore, having less depressive symptoms at baseline was associated with lower initial levels of sleep disturbance and greater improvement in sleep quality over time. There was no discernible association between sleep and mood disturbance in the control group. Across groups, there was a consistent association between older age and greater sleep disturbance (r = 0.34, p < .01). Conclusion: Sleep disturbance appears to be a behavioral target for CBSM in HIV+ women although older age, preintervention levels of depressive mood, and time-varying levels of CORT output may limit improvement in sleep quality over time.

Association Between Health Literacy and Medication Adherence Among Hispanics with Hypertension

BACKGROUND

Poor adherence to prescribed antihypertensive medication is a major contributor to disparities in effective blood pressure control among Hispanics. The purpose of this study was to investigate the association between health literacy level and adherence to antihypertensive medications among Hispanic adults, who self-reported hypertension, controlling for potential covariates of adherence and/or health literacy.

METHODS

We conducted a cross-sectional survey of 1355 Hispanic adults, primarily Dominicans, who self-reported hypertension. Antihypertensive medication adherence and health literacy were evaluated along with covariates, including sociodemographic characteristics, depression, anxiety, and sleep disturbance. Linear regression models were created for health literacy, each covariate, and adherence. Factors found to be significantly associated with adherence in the individual regression models at a p value of < 0.20 were included in a hierarchical multiple linear regression model.

RESULTS

Overall, the majority of participants had low adherence levels to antihypertensive medications (88.4%; n = 1026) and inadequate health literacy (84.9%; n = 1151). When controlling for age, sex, birth country, education level, recruitment location, depression, anxiety, and sleep disturbance, having adequate as compared to inadequate health literacy was associated with a higher adherence score (b = 0.378, p = 0.043). The full model explained 13.6% of the variance in medication adherence (p value < 0.001), but the unique contribution of health literacy to the model was minimal (R² change = 0.003).

CONCLUSIONS

Tailored interventions considering health literacy are needed to support medication adherence in order to improve hypertension outcomes of Hispanics. Additional studies are needed to identify and prioritize factors in the development of targeted and effective adherence interventions for Hispanics with hypertension.

Internalised HIV-stigma, loneliness, depressive symptoms and sleep quality in people living with HIV

OBJECTIVE

People living with HIV (PLWH) commonly report sleep disturbances which are associated with long-term health consequences, including disease progression. PLWH also experience internalised stigma as a result of their HIV status, which can be associated with increased loneliness and depression. Little attention focuses on the impact of these factors on sleep. Therefore, we examined whether internalised HIV-stigma was indirectly related to poorer sleep quality through higher levels of loneliness and depressive symptoms.

DESIGN

181 PLWH from across the United States completed an online survey. Main Study Measures: Internalised HIV-stigma was assessed using the HIV-Stigma Scale, loneliness was assessed using the UCLA-Loneliness Scale-Short Form, depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression Index, and Sleep Quality was assessed using the Pittsburgh Sleep Quality Index.

RESULTS

Internalised HIV-stigma was indirectly associated with poorer global sleep quality and daytime sleep dysfunction through both loneliness and depressive symptoms.

CONCLUSIONS

PLWH who experience HIV-related stigma may experience greater feelings of loneliness, which are related to increased depressive symptoms and poorer sleep quality. Interventions focused on improving sleep in PLWH should focus on multiple factors that influence sleep, including psychosocial factors such as stigma, social isolation and depressive symptoms.

Electrolyte imbalance and sleep problems during anti-retroviral therapy: an under-recognized problem

Human immunodeficiency virus (HIV) infection, and the anti-retroviral therapy (ART) associated complications necessitate that the medical care system keeps evolving for proper management of this group of patients. Electrolyte imbalance and sleep problems are common in patients on ART. Both of these conditions are associated with increased morbidity (such as acute kidney injury, chronic kidney disease, low CD4 count, non-adherence and depression) and mortality. Therefore, screening for both sleep problems and electrolytes imbalance may help to decrease the risk of complications in patients on ART.

Clinical significance of mobile health assessed sleep duration and variability in bipolar disorder

OBJECTIVE

Sleep disturbances are prevalent, persistent, and impairing features of bipolar disorder. However, the near-term and cumulative impact of the severity and variability of sleep disturbances on symptoms and functioning remains unclear. We examined self-reported daily sleep duration and variability in relation to mood symptoms, medication adherence, cognitive functioning, and concurrent daily affect.

METHODS

Forty-one outpatients diagnosed with bipolar disorder were asked to provide daily reports of sleep duration and affect collected via ecological momentary assessment with smartphones over eleven weeks. Measures of depressive and manic symptoms, medication adherence, and cognitive function were collected at baseline and concurrent assessment of affect were collected daily. Analyses examined whether sleep duration or variability were associated with baseline measures and changes in same-day or next-day affect.

RESULTS

Greater sleep duration variability (but not average sleep duration) was associated with greater depressive and manic symptom severity, and lower medication adherence at baseline, and with lower and more variable ratings of positive affect and higher ratings of negative affect. Sleep durations shorter than 7-8 h were associated with lower same-day ratings of positive and higher same-day ratings of negative affect, however this did not extend to next-day affect.

CONCLUSIONS

Greater cumulative day-to-day sleep duration variability, but not average sleep duration, was related to more severe mood symptoms, lower self-reported medication adherence and higher levels of negative affect. Bouts of short- or long-duration sleep had transient impact on affect. Day-to-day sleep variability may be important to incorporate into clinical assessment of sleep disturbances in bipolar disorder.

Engagement in Care, Psychological Distress, and Resilience are Associated with Sleep Quality among HIV-Positive Gay, Bisexual, and Other Men Who Have Sex with Men

OBJECTIVES

We investigated risk and protective factors associated with sleep quality among a national sample of HIV-positive gay, bisexual, and other men who have sex with men (GBMSM).

DESIGN

This study reports on findings from both an eligibility survey and baseline assessment for an online HIV risk reduction intervention.

PARTICIPANTS

There were 16,466 completed eligibility surveys. A total of 1,205 eligible men completed a baseline assessment after consenting to participate in the intervention.

MEASUREMENTS AND RESULTS

Among participants with a completed eligibility survey, men with an HIV-positive status had significantly worse sleep quality and more frequent use of sleep medications during the past month than HIV-negative men. Within the intervention sample (n = 1,205 HIV-positive participants), men with symptoms of anxiety (Adjusted odds ratio [AOR]=2.80; 95% confidence interval [CI]: 1.93-4.06) and depression (AOR=1.66; CI: 1.14-2.43), and who reported a detectable viral load in the past six months (AOR=1.57; CI: 1.06-2.33) had increased odds of poor sleep quality after controlling for demographic characteristics, socioeconomic status, ART use and adherence, substance use, and CD4 count. However, men with greater perceived resilience had decreased odds of reporting poor sleep quality during the past month (AOR=0.68; CI: 0.51-0.89).

CONCLUSIONS

Findings from this online study call for more attention to the role of sleep in immune system functioning and engagement in HIV care. Results further suggest a need to design and test culturally-appropriate sleep health interventions for GBMSM living with HIV that promote protective factors and target particular behavioral changes (i.e., stress reduction, substance use).

The Clarification of Depression and Social Support's Contribution to the Prediction of Antiretroviral Medication Adherence and the Rate of CD4 in People with HIV

With the development of the antiretroviral therapy, the number of the people with HIV is increasing; therefore, identifying the factors affecting HIV is of great importance. This study aimed to investigate the relationship between the antiretroviral medication adherence and the rate of CD4 with depression and social support in the people with HIV. The research method was a descriptive study kind of correlation. The statistical population included all patients with HIV in Shiraz, of whom, 220 people who had referred to the Behavioral Diseases Consultation Center were selected using the available sampling method. Philips et al.'s Social Support Questionnaire, Beck's Depression Questionnaire II, and ACTG Medication Adherence Questionnaire were used as the research tools. Results were analyzed using the stepwise regression and stepwise hierarchical multiple regression. Regression analysis showed that social support and depression variables could predict totally 47% (P<0.001) of changes of medication adherence variable, and depression could predict only 2% (P<0.01) of rate variance of CD4.

Let Visuals Tell the Story: Medication Adherence in Patients with Type II Diabetes Captured by a Novel Ingestion Sensor Platform

BACKGROUND

Chronic diseases such as diabetes require high levels of medication adherence and patient self-management for optimal health outcomes. A novel sensing platform, Digital Health Feedback System (Proteus Digital Health, Redwood City, CA), can for the first time detect medication ingestion events and physiological measures simultaneously, using an edible sensor, personal monitor patch, and paired mobile device. The Digital Health Feedback System (DHFS) generates a large amount of data. Visual analytics of this rich dataset may provide insights into longitudinal patterns of medication adherence in the natural setting and potential relationships between medication adherence and physiological measures that were previously unknown.

OBJECTIVE

Our aim was to use modern methods of visual analytics to represent continuous and discrete data from the DHFS, plotting multiple different data types simultaneously to evaluate the potential of the DHFS to capture longitudinal patterns of medication-taking behavior and self-management in individual patients with type II diabetes.

METHODS

Visualizations were generated using time domain methods of oral metformin medication adherence and physiological data obtained by the DHFS use in 5 patients with type II diabetes over 37-42 days. The DHFS captured at-home metformin adherence, heart rate, activity, and sleep/rest. A mobile glucose monitor captured glucose testing and level (mg/dl). Algorithms were developed to analyze data over varying time periods: across the entire study, daily, and weekly. Following visualization analysis, correlations between sleep/rest and medication ingestion were calculated across all subjects.

RESULTS

A total of 197 subject days, encompassing 141,840 data events were analyzed. Individual continuous patch use varied between 87-98%. On average, the cohort took 78% (SD 12) of prescribed medication and took 77% (SD 26) within the prescribed ±2-hour time window. Average activity levels per subjects ranged from 4000-12,000 steps per day. The combination of activity level and heart rate indicated different levels of cardiovascular fitness between subjects. Visualizations over the entire study captured the longitudinal pattern of missed doses (the majority of which took place in the evening), the timing of ingestions in individual subjects, and the range of medication ingestion timing, which varied from 1.5-2.4 hours (Subject 3) to 11 hours (Subject 2). Individual morning self-management patterns over the study period were obtained by combining the times of waking, metformin ingestion, and glucose measurement. Visualizations combining multiple data streams over a 24-hour period captured patterns of broad daily events: when subjects rose in the morning, tested their blood glucose, took their medications, went to bed, hours of sleep/rest, and level of activity during the day. Visualizations identified highly consistent daily patterns in Subject 3, the most adherent participant. Erratic daily patterns including sleep/rest were demonstrated in Subject 2, the least adherent subject. Correlation between sleep /rest and medication ingestion in each individual subject was evaluated. Subjects 2 and 4 showed correlation between amount of sleep/rest over a 24-hour period and medication-taking the following day (Subject 2: r=.47, P<.02; Subject 4: r=.35, P<.05). With Subject 2, sleep/rest disruptions during the night were highly correlated (r=.47, P<.009) with missing doses the following day.

CONCLUSIONS

Visualizations integrating medication ingestion and physiological data from the DHFS over varying time intervals captured detailed individual longitudinal patterns of medication adherence and self-management in the natural setting. Visualizing multiple data streams simultaneously, providing a data-rich representation, revealed information that would not have been shown by plotting data streams individually. Such analyses provided data far beyond traditional adherence summary statistics and may form the foundation of future personalized predictive interventions to drive longitudinal adherence and support optimal self-management in chronic diseases such as diabetes.

[Poor quality of sleep associated with low adherence to highly active antiretroviral therapy in Peruvian patients with HIV/AIDS]

This cross-sectional study analyzed the association between poor quality of sleep and adherence to highly active antiretroviral therapy (HAART) in 389 Peruvian patients with HIV/AIDS. Poor quality of sleep was measured with the Pittsburgh Sleep Quality Index (PSQI) and adherence with the CEAT-VIH (Peruvian adaptation). A Poisson generalized linear model with robust standard errors was used to estimate prevalence ratios and 95%CI. A crude model showed that mild, moderate, and severe poor quality of sleep were associated with inadequate treatment adherence. In the adjusted model for variables associated in the bivariate analysis or variables theoretically associated with adherence, only moderate/severe poor quality of sleep remained associated (PR = 1.34, 95%CI: 1.17-1.54; and PR = 1.34, 95%CI: 1.16-1.57, respectively). The study concluded that moderate/severe poor quality of sleep was independently associated with adherence to HAART. Assessing quality of sleep may be helpful in the comprehensive evaluation of HIV patients.

Depressive symptoms and fatigue as mediators of relationship between poor sleep factors and medication adherence in HIV-positive women

Patients living with HIV commonly experience sleep disturbances, depression, excessive daytime sleepiness and fatigue, which negatively affect antiretroviral medication adherence. Few studies have examined relationships between these symptoms and medication adherence in women living with HIV or examine the mechanisms through which these symptoms affect adherence. The purpose of this study was to examine the associations between sleep quality, excessive daytime sleepiness and medication adherence, and energy/fatigue and depression as mediators of these relationships among 206 women living with HIV. Correlations, t-tests and hierarchical regression analysis were utilised. The majority of participants (93.2%) were African American or Black. The average age of participants was 43.3 years and average years infected was 9.6. More than half of the women reported poor sleep quality and, on average, participants reported moderate daytime sleepiness, high depressive symptoms and moderate levels of fatigue. Additionally, both depression and low energy/fatigue were identified as significant mediators of the relationship between sleep quality and medication adherence. Depression also significantly mediated the relationship between excessive daytime sleepiness and medication adherence. The findings from this study highlight the impact of sleep on medication adherence and associated mechanisms and emphasise the need for healthcare providers to assess and address sleep factors when providing care for patients living with HIV.

Self-reported sleep disturbances in HIV-infected people: a meta-analysis of prevalence and moderators

OBJECTIVE

Our goal was to estimate the pooled prevalence of self-reported sleep disturbances in HIV-infected people through meta-analysis, taking into account variations in geographic region, gender, age group, CD4 counts, and instrument used to measure sleep disturbances.

METHODS

The authors conducted systematic searches of PubMed and PsycINFO to include studies that met our criteria. A random effect meta-analysis model was used to estimate the pooled prevalence of self-reported sleep disturbances in HIV-infected people. The potential moderators of self-reported sleep disturbances were explored with meta-regression analysis.

RESULTS

Twenty-seven articles comprising a total of 9246 HIV-positive participants were finally included in our analysis. The overall prevalence of self-reported sleep disturbances in HIV-infected people was 58.0% (95% CI = 49.6-66.1). Meta-regression analysis indicates that geographic region, gender, and instrument significantly explain part of the heterogeneity of the prevalence estimates between the included studies.

CONCLUSION

The findings suggest that HIV-infected people suffer from a heavy burden of sleep disturbances. It is therefore recommended that sleep quality should be routinely assessed in HIV-infected people in order to identify the medical treatment needs and the potential impact of sleep problems on antiretroviral therapy outcomes in this population.

Predictors of cure among HIV co-infected multidrug-resistant TB patients at Sizwe Tropical Disease Hospital Johannesburg, South Africa

BACKGROUND

The global incidence of multidrug-resistant tuberculosis (MDR-TB) is rising, especially among HIV infected patients, despite intervention programs. Limited data are available on outcomes of MDR-TB treatment, specifically in a cohort of HIV co-infected patients in sub-Saharan Africa. The objective of this study was to determine the predictors of cure among MDR-TB HIV co-infected patients.

METHODS

A retrospective review of 1200 medical records of HIV co-infected MDR-TB patients was performed at Sizwe Tropical Disease Hospital, Johannesburg covering the period 2007 to 2010. Logistic regression analysis was done to identify predictors of cure.

RESULTS

Of 1137 patients included in the analysis, 29.8% (339/1137) were cured, 16.5% (188/1137) completed treatment, 22.3% (254/1137) defaulted treatment, 2.9% (33/1137) failed treatment and 22.7% (258/1137) died while on treatment. The remaining 5.7% (65/1137) were transferred-out or still-on-treatment. There was a significant interaction between sex and timing of antiretroviral treatment (ART) initiation (p=0.008). Factors predicting cure were male patients on ART prior to commencing MDR-TB treatment (OR 1.87, [1.11-3.13]), CD4(+) cell counts between 201-349 (OR 2.06, [1.10-3.84]) and ≥ 350 cells/mm³ (OR 1.98, [0.98-3.97]). Negative predictors of cure included the presence of cavitary lesions on chest x-rays (OR 0.55, [0.38-0.78]) and modified individualised regimen at baseline (OR 0.62, [0.42-0.92]).

CONCLUSIONS

Cure was higher in males on ART prior to initiating MDR-TB treatment compared with males on ART after initiating MDR-TB treatment. The inverse was the case among females. Therefore, future research should explore the biological and behavioural mechanisms that may possibly be responsible for this observed trend. This will help improve MDR-TB treatment outcomes in HIV co-infected patients on ART.

Depression and adherence to antiretroviral therapy in low-, middle- and high-income countries: a systematic review and meta-analysis

We investigated the associations between depressive symptoms and adherence to antiretroviral therapy (ART) among people living with HIV (PLHIV). We searched the PubMed, EMBASE and Cochrane CENTRAL databases for studies that reported an association between depression and adherence to ART as a primary or secondary outcome. We used a random-effect model to pool the risk estimates from the individual studies. The odds ratio (OR) with their 95 % CIs were used as summary estimates. Of 2861 citations, 111 studies that recruited 42,366 PLHIV met our inclusion criteria. When reported, the rate of PLHIV with depressive symptoms ranged from 12.8 to 78 % and the proportion of PLHIV who achieved good adherence (≥ 80 %) ranged from 20 to 98 %. There were no significant differences in rate of depressive symptoms in PLHIV by country income group; however, the proportion of PLHIV who achieved good adherence was significantly higher in lower-income countries (as defined in the 2012 World Bank Country Income Groups) (pooled rate=86 %) compared to higher-income countries (pooled rate=67.5 %; p< .05). We found that the likelihood of achieving good ART adherence was 42 % lower among those with depressive symptoms compared to those without (pooled OR=0.58, 95 % CI 0.55 to 0.62). The relationship between depressive symptoms and adherence to ART was consistent across the country's income group, study design and adherence rates. We found that the magnitude of the association significantly decreases with more recent publications and increasing study sample size. The higher the prevalence of depressive symptoms of PLHIV recruited in the studies, the lower the likelihood of achieving good adherence to ART. In conclusion, the likelihood of achieving good adherence was lower among those with depressive symptoms compared to those without.

Increase in single-tablet regimen use and associated improvements in adherence-related outcomes in HIV-infected women

INTRODUCTION

The use of single-tablet antiretroviral therapy (ART) regimens and its implications on adherence among HIV-infected women have not been well described.

METHODS

Participants were enrolled in the Women's Interagency HIV Study, a longitudinal study of HIV infection in US women. We examined semiannual trends in single-tablet regimen use and ART adherence, defined as self-reported 95% adherence in the past 6 months, during 2006-2013. In a nested cohort study, we assessed the comparative effectiveness of a single-tablet versus a multiple-tablet regimen with respect to adherence, virologic suppression, quality of life, and AIDS-defining events, using propensity score matching to account for demographic, behavioral, and clinical confounders. We also examined these outcomes in a subset of women switching from a multiple- to single-tablet regimen using a case-crossover design.

RESULTS

We included 15,523 person-visits, representing 1727 women (53% black, 29% Hispanic, 25% IDU, median age 47). Use of single-tablet regimens among ART users increased from 7% in 2006% to 27% in 2013; adherence increased from 78% to 85% during the same period (both P < 0.001). Single-tablet regimen use was significantly associated with increased adherence (adjusted risk ratio: 1.05; 95% confidence interval: 1.03 to 1.08) and virologic suppression (risk ratio: 1.06; 95% confidence interval: 1.01 to 1.11), while associations with improved quality of life and fewer AIDS-defining events did not achieve statistical significance. Similar findings were observed among the subset of switchers.

CONCLUSIONS

Single-tablet regimen use was associated with increased adherence and virologic suppression. Despite this, 15% of women prescribed ART were still not optimally adherent; additional interventions are needed to maximize therapeutic benefits.

Factors related to advanced stages of change in a clinical sample of adolescents

BACKGROUND

The purpose of the present study was to examine the factors predicting a greater motivation to change in a clinical sample of adolescents.

METHOD

A total of 107 adolescents participated in this research prior to beginning outpatient treatment. Participants completed a modified version of the Motivational Stages of Change for Adolescents Recovering from an ED, the Difficulties in Emotional Regulation Scale and the Behavioral Assessment System for Children-Self-Report.

RESULTS

More advanced stages of change were associated with better parent-adolescent relationships and better emotional regulation.

CONCLUSION

Incorporating parents in treatment to enhance parent-adolescent relationships and instructing parents in emotional regulation techniques to assist the adolescent may enhance their motivation to recover.

Randomized controlled trial to evaluate the impact of pharmaceutical care on therapeutic success in HIV-infected patients in Southern Brazil

A non-blinded randomized controlled trial evaluated efficacy of pharmaceutical care (PC) (Dáder method) on self-reported antiretroviral adherence and undetectable plasma viral load (UPVL), compared with usual care (UC) in HIV-positive patients in Brazil. Most were male (63 %), mean age 40.3 years (SD = 10). After 12 months, 79.8 % of those receiving PC versus 73.8 % in UC were adherent (RR 1.05, 95 % CI 0.95-1.15, P = 0.35), and 50.3 versus 49.8 % (PC vs. UC, respectively) had UPVL (RR 1.08, 95 % CI 0.97-1.20, P = 0.15). Factors associated with self-reported adherence were regular employment, UPVL, no depressive symptoms, and lower pill load in the treatment regimen. Older age, education, CD4 count <200 cells/mm(3), and shorter treatment duration were associated with UPVL. Of 94 reported drug-related problems, 43 % resolved. In subgroup analyses of patients who experienced therapeutic failure and who were non-adherent at the beginning of the trial (N = 50), no differences were found in UPVL (HR 1.35, 95 % CI 0.57-3.19). Only education level (>12 years) was independently predictive of viral suppression (HR 7.47, 95 % CI 1.69-32.91). In conclusion, PC was not associated with increased self-reported adherence to ART or UPVL in patients treated at a health care facility in southern Brazil. The study suggests, however, that PC could be effective for the subgroup of patients with poor adherence.

Sleep ameliorating effects of acupuncture in a psychiatric population

The interest of psychiatric patients for complementary medicine, such as acupuncture, is stable, but effect studies in psychiatry remain scarce. In this pilot study, the effects of 3 months of acupuncture treatment on sleep were evaluated and compared between a group of patients with schizophrenia (n = 16) and a group with depression (n = 16). Healthy controls were included in order to establish reference values (n = 8). Patients with schizophrenia and depression were randomly assigned to either a waiting list or a treatment condition. The Pittsburgh Sleep Quality Inventory was completed before and after the acupuncture treatment (individualized and according to traditional Chinese medicine principles) or the waiting list condition. Both acupuncture groups showed significant lower scores on the sleep inventory, which was not the case for the waiting list condition. Moreover, it was found that the effectiveness of the acupuncture treatment was higher in the patients with schizophrenia than in the patients with depression. Acupuncture seems able to improve sleep in this convenient sample of patients with long-lasting psychiatric problems and may be a suitable and cost-effective add-on treatment for this group, particularly if conducted group-wise.

The role of depression in medication adherence among heart failure patients

The purpose of the study was to explore the association between depression and medication adherence in heart failure (HF) patients. Studies have shown that people with depression are likely to be nonadherent to their prescribed medication treatment. But other studies suggest that nonadherence may be overestimated by people with depression. A total of 244 adults with Stage C HF completed the study. Self-reported medication adherence was obtained using the Basel Assessment of Adherence Scale (BAAS); objective data on medication adherence were collected using the electronic Medication Event Monitoring System (MEMS). Depression was measured via self-report with the Patient Health Questionnaire (PHQ-9). There was a significant difference between depressed and nondepressed participants in self-reported medication nonadherence (p = .008), but not in objectively measured medication nonadherence (p = .72). The depressed sample was 2.3 times more likely to self-report poor medication adherence than those who were nondepressed (p = .006).

Factors associated with suboptimal adherence to antiretroviral therapy in Viet Nam: a cross-sectional study using audio computer-assisted self-interview (ACASI)

Background

Optimal adherence to antiretroviral therapy (ART) is necessary for people living with HIV/AIDS (PLHIV). There have been relatively few systematic analyses of factors that promote or inhibit adherence to antiretroviral therapy among PLHIV in Asia. This study assessed ART adherence and examined factors associated with suboptimal adherence in northern Viet Nam.

Methods

Data from 615 PLHIV on ART in two urban and three rural outpatient clinics were collected by medical record extraction and from patient interviews using audio computer-assisted self-interview (ACASI).

Results

The prevalence of suboptimal adherence was estimated to be 24.9% via a visual analogue scale (VAS) of past-month dose-missing and 29.1% using a modified Adult AIDS Clinical Trial Group scale for on-time dose-taking in the past 4 days. Factors significantly associated with the more conservative VAS score were: depression (p < 0.001), side-effect experiences (p < 0.001), heavy alcohol use (p = 0.001), chance health locus of control (p = 0.003), low perceived quality of information from care providers (p = 0.04) and low social connectedness (p = 0.03). Illicit drug use alone was not significantly associated with suboptimal adherence, but interacted with heavy alcohol use to reduce adherence (p < 0.001).

Conclusions

This is the largest survey of ART adherence yet reported from Asia and the first in a developing country to use the ACASI method in this context. The evidence strongly indicates that ART services in Viet Nam should include screening and treatment for depression, linkage with alcohol and/or drug dependence treatment, and counselling to address the belief that chance or luck determines health outcomes.

Qualitative study of the quality of sleep in marginalized individuals living with HIV

Sleep disturbances have been reported to be higher in human immunodeficiency virus (HIV)-infected individuals compared to the general population. Despite the consequences of poor quality of sleep (QOS), research regarding sleep disturbances in HIV infection is lacking and many questions regarding correlates of poor QOS, especially in marginalized populations, remain unanswered. We conducted one-on-one qualitative interviews with 14 marginalized HIV-infected individuals who reported poor QOS to examine self-reported correlates of sleep quality and explore the relationship between QOS and antiretroviral adherence. Findings suggest a complex and multidimensional impact of mental health issues, structural factors, and physical conditions on QOS of these individuals. Those reporting poor QOS as a barrier to antiretroviral adherence reported lower adherence due to falling asleep or feeling too tired to take medications in comparison to those who did not express this adherence barrier. These interviews underscore the importance of inquiries into a patient's QOS as an opportunity to discuss topics such as adherence, depression, suicidal ideation, and substance use.

The impact of DSM-IV mental disorders on adherence to combination antiretroviral therapy among adult persons living with HIV/AIDS: a systematic review

This is a systematic review of eighty-two published studies investigating the impact of DSM-IV mental disorders on combination antiretroviral therapy (cART) adherence and persistence among persons living with HIV/AIDS (PLWHA). Sixty-two articles examined depression, with 58 % (N = 32/62) finding lower cART adherence and persistence. Seventeen articles examined one or more anxiety disorders, with the majority finding no association with cART adherence or persistence. Eighty percent of the studies that evaluated the impact of psychotic (N = 3), bipolar (N = 5) and personality disorders (N = 2) on cART adherence and persistence also found no association. Seven out of the nine studies (78 %) evaluating the impact of antidepressant treatment (ADT) on cART adherence found improvement. Adherence and depression measurements varied significantly in studies; common research measurements would improve data harmonization. More research specifically addressing the impact of other mental disorders besides depression on cART adherence and RCTs evaluating ADT on cART adherence are also needed.

A pilot study of sleep quality and rest-activity patterns in persons living with HIV

As much as 73% of persons living with HIV (PLWH) experience sleep disturbances. It has been more than 10 years since the last study that objectively measured sleep behaviors in persons with HIV. The purpose of this pilot study was to explore sleep quality and rest-activity patterns in PLWH. Eight participants completed a sleep diary and 24-hour actigraphy for 1 week. Compared to accepted norms for "good sleepers," sleep diaries described moderate sleep disturbance, and actigraphy revealed severe sleep disturbance. Bedtime was variable from day to day. Analysis of 24-hour rest-activity patterns from actigraphy also indicated disorganization of sleep timing across days. Results of this pilot study suggest that sleep disturbance remains problematic in PLWH despite advancements in the disease management. Pharmacological interventions are effective but generally recommended for short-term use. Behavioral treatments may be useful for longer-term management of sleep patterns in PLWH, but further research is needed.

Qualidade do sono em portadores do vírus da imunodeficiência humana

Este estudo teve por objetivo caracterizar a qualidade do sono de pessoas com o vírus da imunodeficiência humana (HIV) - AIDS - , com ou sem manifestações clínicas e sob tratamento ambulatorial. Para tal, foi realizada pesquisa descritiva e transversal. Os instrumentos utilizados foram: Questionário de Caracterização Sociodemográfica e Clínica; Índice de Qualidade de Sono de Pittsburgh (PSQI-BR). Participaram da pesquisa 122 pacientes (55,7% de homens e 44,3% de mulheres, com idade média de 42,3 (± 8,9 anos), dos quais 53,3% referiram apresentar sono de boa qualidade e 46,7%, sono de má qualidade. Dormiam, em média, 7,3 (± 1,8) horas, com latência de 23,2 (± 26,2) minutos e eficiência do sono de 87,8% (± 14,4). Observou-se associação significativa entre o sono de boa qualidade e os seguintes fatores: ter companheiro(a); apresentar carga viral indetectável; manter comportamento de risco. Recomenda-se que os profissionais de enfermagem incluam sistematicamente questões sobre o sono ao avaliarem o paciente com HIV/AIDS, detectando alterações precocemente e reunindo subsídios para o planejamento de intervenções.

Women and vulnerability to HAART non-adherence: a literature review of treatment adherence by gender from 2000 to 2011

A literature review of original research articles on adherence to antiretroviral therapy (ART) in developed countries, covering January 2000 to June 2011, was conducted to determine if gender differences exist in the prevalence of nonadherence to ART. Of the 1,255 articles reviewed, only 189 included data on the proportion of the study population that was adherent and only 57 (30.2%) of these reported proportional adherence values by gender. While comparing articles was challenging because of varied reporting strategies, women generally exhibit poorer adherence than men. Thirty of the 44 articles (68.2%) that reported comparative data on adherence by gender found women to be less adherent than men. Ten articles (17.5%) reported significant differences in proportional adherence by gender, nine of which showed women to be less adherent than men. These findings suggest that in multiple studies from developed countries, female gender often predicts lower adherence. The unique circumstances of HIV-positive women require specialized care to increase adherence to ART.
