Adherence to Antiretroviral Therapy Among HIV Patients in India: A Systematic Review and Meta-analysis.

We conducted a systematic review and meta-analysis to estimate the prevalence of adherence to antiretroviral therapy (ART) in India, the third largest HIV epidemic in the world. We identified peer reviewed literature published between 2007 and 2017 to extract data on ART adherence. We estimated pooled prevalence of adherence to ART using a random-effects model. Thirty-two eligible studies (n = 11,543) were included in the meta-analysis. Studies were mostly clustered in the southern and western Indian states. Overall, 77% (95% Confidence Interval 73-82; I2 = 96.80%) of patients had optimum adherence to ART. Women had higher prevalence of optimum adherence compared to men. Depression or anxiety were significant risk factors in seven of the fifteen studies reporting determinants of nonadherence. Studies should be performed to explore the reasons for gender gap in ART adherence and HIV program in India should prioritize mental health issues among HIV patients to improve ART adherence.

Mild Respiratory Illness Among Young Children Caused by Highly Pathogenic Avian Influenza A (H5N1) Virus Infection in Dhaka, Bangladesh, 2011.

Background: In March 2011, a multidisciplinary team investigated 2 human cases of highly pathogenic avian influenza A(H5N1) virus infection, detected through population-based active surveillance for influenza in Bangladesh, to assess transmission and contain further spread. Methods: We collected clinical and exposure history of the case patients and monitored persons coming within 1 m of a case patient during their infectious period. Nasopharyngeal wash specimens from case patients and contacts were tested with real-time reverse-transcription polymerase chain reaction, and virus culture and isolates were characterized. Serum samples were tested with microneutralization and hemagglutination inhibition assays. We tested poultry, wild bird, and environmental samples from case patient households and surrounding areas for influenza viruses. Results: Two previously healthy case patients, aged 13 and 31 months, had influenzalike illness and fully recovered. They had contact with poultry 7 and 10 days before illness onset, respectively. None of their 57 contacts were subsequently ill. Clade 2.2.2.1 highly pathogenic avian influenza H5N1 viruses were isolated from the case patients and from chicken fecal samples collected at the live bird markets near the patients' dwellings. Conclusion: Identification of H5N1 cases through population-based surveillance suggests possible additional undetected cases throughout Bangladesh and highlights the importance of surveillance for mild respiratory illness among populations frequently exposed to infected poultry.

Low-Cost National Media-Based Surveillance System for Public Health Events, Bangladesh.

We assessed a media-based public health surveillance system in Bangladesh during 2010-2011. The system is a highly effective, low-cost, locally appropriate, and sustainable outbreak detection tool that could be used in other low-income, resource-poor settings to meet the capacity for surveillance outlined in the International Health Regulations 2005.

Healthcare Utilization in the Postpartum Period Among Illinois Women with Medicaid Paid Claims for Delivery, 2009-2010.

Purpose Postpartum care can provide the critical link between pregnancy and well-woman healthcare, improving women's health during the interconception period and beyond. However, little is known about current utilization patterns. This study describes the patterns of postpartum care experienced by Illinois women with Medicaid-paid deliveries. Methods Medicaid claims for women delivering infants in Illinois in 2009-2010 were analyzed for the receipt, timing and patterns of postpartum care, as identified through International Classification of Diseases Revision 9-Clinical Modification and Current Procedural Terminology© codes for routine postpartum care (43.4 % of visits), other postpartum services (e.g., depression screening, family planning), and other office visits for non-acute care. Results Over 90,000 visits to 55,577 women were identified, with 81.1 % of women experiencing any care during the first 90 days postpartum. Approximately 40 % had one visit, while 31 and 29 % had two and three or more visits, respectively. Thirty-four percent had their first visit <21 days postpartum, while 56 % had the first visit between 21 and 56 days postpartum. Compared with non-Hispanic whites, African-Americans had lower rates of receiving any care (73.6 vs. 86.5 %), fewer visits (48.0 vs. 33.5 % with only one visit), and later first visits (13.6 vs. 7.3 %, >56 days). Conclusions for Practice The vast majority of Illinois women with Medicaid-paid deliveries interact with the healthcare system during the first 3 months postpartum, though not always for a routine postpartum visit. Strategies to optimize postpartum health should encourage a higher level of coordination among services and linkage to well-woman care to improve subsequent women and infants' health outcomes.

Early detection of pandemic (H1N1) 2009, Bangladesh.

To explore Bangladesh's ability to detect novel influenza, we examined a series of laboratory-confirmed pandemic (H1N1) 2009 cases. During June-July 2009, event-based surveillance identified 30 case-patients (57% travelers); starting July 29, sentinel sites identified 252 case-patients (1% travelers). Surveillance facilitated response weeks before the spread of pandemic (H1N1) 2009 infection to the general population.

Swab protocol for rapid laboratory diagnosis of cutaneous anthrax.

The clinical laboratory diagnosis of cutaneous anthrax is generally established by conventional microbiological methods, such as culture and directly straining smears of clinical specimens. However, these methods rely on recovery of viable Bacillus anthracis cells from swabs of cutaneous lesions and often yield negative results. This study developed a rapid protocol for detection of B. anthracis on clinical swabs. Three types of swabs, flocked-nylon, rayon, and polyester, were evaluated by 3 extraction methods, the swab extraction tube system (SETS), sonication, and vortex. Swabs were spiked with virulent B. anthracis cells, and the methods were compared for their efficiency over time by culture and real-time PCR. Viability testing indicated that the SETS yielded greater recovery of B. anthracis from 1-day-old swabs; however, reduced viability was consistent for the 3 extraction methods after 7 days and nonviability was consistent by 28 days. Real-time PCR analysis showed that the PCR amplification was not impacted by time for any swab extraction method and that the SETS method provided the lowest limit of detection. When evaluated using lesion swabs from cutaneous anthrax outbreaks, the SETS yielded culture-negative, PCR-positive results. This study demonstrated that swab extraction methods differ in their efficiency of recovery of viable B. anthracis cells. Furthermore, the results indicated that culture is not reliable for isolation of B. anthracis from swabs at ≥ 7 days. Thus, we recommend the use of the SETS method with subsequent testing by culture and real-time PCR for diagnosis of cutaneous anthrax from clinical swabs of cutaneous lesions.

Identification and phylogenetic analysis of orf viruses isolated from outbreaks in goats of Assam, a northeastern state of India.

Two outbreaks of orf virus (ORFV) (a parapoxvirus) infection in goats, which occurred in Golaghat and Kamrup districts of Assam, a northeastern part of India, were investigated. The disease was diagnosed by standard virological and molecular techniques. The entire protein-coding region of B2L gene of two isolates were cloned and sequenced. Phylogenetic analysis based on B2L amino acid sequences showed that the ORFVs identified in these outbreaks were closely related to each other and both were closer to ORFV-Shahjahanpur 82/04 isolate from north India. The present study revealed that the precise characterization of the genomic region (B2L gene) might provide evidence for the genetic variation and movement of circulating ORFV strains in India.

Lethal factor toxemia and anti-protective antigen antibody activity in naturally acquired cutaneous anthrax.

Cutaneous anthrax outbreaks occurred in Bangladesh from August to October 2009. As part of the epidemiological response and to confirm anthrax diagnoses, serum samples were collected from suspected case patients with observed cutaneous lesions. Anthrax lethal factor (LF), anti-protective antigen (anti-PA) immunoglobulin G (IgG), and anthrax lethal toxin neutralization activity (TNA) levels were determined in acute and convalescent serum of 26 case patients with suspected cutaneous anthrax from the first and largest of these outbreaks. LF (0.005-1.264 ng/mL) was detected in acute serum from 18 of 26 individuals. Anti-PA IgG and TNA were detected in sera from the same 18 individuals and ranged from 10.0 to 679.5 µg/mL and 27 to 593 units, respectively. Seroconversion to serum anti-PA and TNA was found only in case patients with measurable toxemia. This is the first report of quantitative analysis of serum LF in cutaneous anthrax and the first to associate acute stage toxemia with subsequent antitoxin antibody responses.

Antiretroviral therapy adherence among treatment-naive HIV-infected patients.

OBJECTIVE: To determine the incidence of antiretroviral therapy (ART) adherence among treatment-naive HIV-infected patients and to evaluate the impact of single-tablet regimen (STR) on ART adherence among this population. DESIGN: Retrospective cohort study. METHODS: We used a nationally representative sample of IQVIA LRx Lifelink individual level pharmacy claims database during 2011-2016, and defined adult patients with index date (first complete ART regimen prescription fill date) after 30 June 2011 as treatment naïve. We estimated ART adherence, measured as the proportion of days covered during 1 year following the index date. We conducted multivariable analysis to identify the factors associated with optimum adherence (≥90% proportion of days covered). We also compared adherence between patients prescribed STR and multiple-tablet regimens among those prescribed integrase strand transfer inhibitor-based or nonnucleoside reverse transcriptase inhibitor-based regimens. RESULTS: Overall 42.9% of the patients were optimally adherent. Adherence was significantly lower among blacks, Hispanics and patients in low-income communities. Adjusting for the covariates, patients on STR had higher incidence of optimum adherence compared with those on multiple-tablet regimens among patients on integrase strand transfer inhibitor-based regimens [49 vs. 24%, relative risk, 2.16 (95% confidence interval: 1.96-2.26)], but no significant difference was observed among those on nonnucleoside reverse transcriptase inhibitor-based regimen [45 vs. 45%, relative risk, 1.12 (95% confidence interval: 0.99-1.26)]. CONCLUSION: Low ART adherence observed among treatment-naive patients in this nationally representative study suggests the need for public health interventions to improve adherence among this population.

Association Between Pharmacy Closures and Adherence to Cardiovascular Medications Among Older US Adults.

Importance: It is unknown whether and how pharmacy closures alter medication adherence. Objective: To examine the association between pharmacy closures and adherence to statins, ß-blockers, and oral anticoagulants among adults 50 years or older in the United States. Design, Setting, and Participants: In this retrospective cohort study, comparative interrupted time series analyses were performed using a nationally representative 5% random sample of anonymized, longitudinal, individual-level pharmacy claims from IQVIA LRx LifeLink. Analyses included all prescription claims for individuals followed up between January 1, 2011, and December 31, 2016. Separate cohorts were derived for users of statins, ß-blockers, and oral anticoagulants. The differential association of pharmacy closure was examined as a function of baseline adherence, pharmacy, and individual characteristics. Main Outcomes and Measures: Difference in monthly adherence, measured as proportion of days covered, during 12-month baseline and follow-up periods among patients using a pharmacy that subsequently closed (closure cohort) compared with their counterparts (control cohort). Results: Among 3 089 803 individuals filling at least 1 statin prescription between January 1, 2011, and December 31, 2016 (mean [SD] age, 66.3 [9.3] years; 52.0% female), 3.0% (n = 92 287) filled at a pharmacy that subsequently closed. Before closure, monthly adherence was similar in the closure and control cohorts (mean [SD], 70.5% [26.7%] vs 70.7% [26.5%]). In multivariable models, individuals filling at pharmacies that closed experienced an immediate and significant decline (on average, an absolute change of -5.90%; 95% CI, -6.12% to -5.69%) in statin adherence during the first 3 months after closure compared with their counterparts. This difference persisted over 12 months of follow-up. A similar decline in adherence was observed when examining cohorts using ß-blockers (-5.71%; 95% CI, -5.96% to -5.46%) or oral anticoagulants (-5.63%; 95% CI, -6.24% to -5.01%). The mean association of pharmacy closure with adherence was greater among individuals using independent pharmacies (-7.89%; 95% CI, -8.32% to -7.47%) or living in neighborhoods with fewer pharmacies (-7.98%; 95% CI, -8.50% to -7.47%) compared with their counterparts. Conclusions and Relevance: Pharmacy closures are associated with persistent, clinically significant declines in adherence to cardiovascular medications among older adults in the United States. Efforts to reduce nonadherence to prescription medications should consider the role of pharmacy closures, especially among patients at highest risk.

Acceptability, Feasibility, and Preliminary Efficacy of a Theory-Based Relational Embodied Conversational Agent Mobile Phone Intervention to Promote HIV Medication Adherence in Young HIV-Positive African American MSM.

An embodied conversational agent can serve as a relational agent and provide information, motivation, and behavioral skills. To evaluate the feasibility, acceptability, and preliminary efficacy of My Personal Health Guide, a theory-based mobile-delivered embodied conversational agent intervention to improve adherence to antiretroviral therapy in young African American men who have sex with men, we conducted this prospective pilot study using a 3-month pre-post design. Outcome measures included adherence, acceptability, feasibility, pre versus post health literacy, and pre versus post self-efficacy. There were 43 participants. Pill count adherence > 80% improved from 62% at baseline to 88% at follow-up (p = .05). The acceptability of the app was high. Feasibility issues identified included loss of usage data from unplanned participant app deletion. Health literacy improved whereas self-efficacy was high at baseline and follow-up. This pilot study of My Personal Health Guide demonstrated acceptability and preliminary efficacy in improving adherence in this important population.

Self-efficacy and ability to read as factors associated with antiretroviral therapy adherence in an HIV-infected population.

Determining the barriers and facilitators of antiretroviral adherence among former and current substance users may be useful in the creation of successful interventions that target this hard-to-reach population. We performed a cross-sectional study of HIV-infected patients (N = 123) prescribed antiretroviral therapy at four Chicago healthcare venues. Bivariate and multivariable analyses were performed to determine factors associated with non-adherence based on definitions of non-adherence (any missed doses) within the past 4-day, 14-day, and 1-month time periods. Factors consistently associated with non-adherence in bivariate and multivariate analyses, regardless of duration of non-adherence definition, were lower confidence in taking medication consistently and less self-reported ability to read. These data reveal the importance of self-efficacy and ability to read (rather than specific knowledge of CD4 and viral load definitions) in the design of interventions in a population of HIV-infected persons with significant substance use.

Slips, Trips, and Falls Among Home Care Aides: A Mixed-Methods Study.

OBJECTIVE: To address the gap of knowledge about slips, trips, and falls (STFs) among home care aides (HCAs) who work in clients' homes. METHODS: This mixed method study used survey and focus group data of HCAs in a Medicaid-funded homecare program. RESULTS: STFs were common with over 12% of HCAs reporting occurrence in the previous 12 months, of whom 58% fell to the ground. Both survey and focus group data identified ice, clutter, workload, rushing and other hazards. Focus group data explained the reasons for not reporting STFs, even among those who sustained injury, and added HCAs' voices to the understanding of causes, consequences and prevention strategies for STFs. CONCLUSIONS: Empowering HCAs with knowledge, training, and involvement may transform "near miss" STFs into opportunities to prevent STFs among care workers and their clients.

Effectiveness of a Faith-placed Cardiovascular Health Promotion Intervention for Rural Adults.

INTRODUCTION: Cardiovascular disease (CVD) is the leading cause of mortality in the US. Further, rural US adults experience disproportionately high CVD prevalence and mortality compared to non-rural. Cardiovascular risk-reduction interventions for rural adults have shown short-term effectiveness, but long-term maintenance of outcomes remains a challenge. Faith organizations offer promise as collaborative partners for translating evidence-based interventions to reduce CVD. METHODS: We adapted and implemented a collaborative, faith-placed, CVD risk-reduction intervention in rural Illinois. We used a quasi-experimental, pre-post design to compare changes in dietary and physical activity among participants. Intervention components included Heart Smart for Women (HSFW), an evidence-based program implemented weekly for 12 weeks followed by Heart Smart Maintenance (HSM), implemented monthly for two years. Participants engaged in HSFW only, HSM only, or both. We used regression and generalized estimating equations models to examine changes in outcomes after one year. RESULTS: Among participants who completed both baseline and one-year surveys (n = 131), HSFW+HSM participants had significantly higher vegetable consumption (p = .007) and combined fruit/vegetable consumption (p = .01) compared to the HSM-only group at one year. We found no differences in physical activity. CONCLUSION: Improving and maintaining CVD-risk behaviors is a persistent challenge in rural populations. Advancing research to improve our understanding of effective translation of CVD risk-reduction interventions in rural populations is critical.

A Realistic Talking Human Embodied Agent Mobile Phone Intervention to Promote HIV Medication Adherence and Retention in Care in Young HIV-Positive African American Men Who Have Sex With Men: Qualitative Study.

BACKGROUND: Avatars and embodied agents are a promising innovation for human health intervention because they may serve as a relational agent that might augment user engagement in a behavioral change intervention and motivate behavioral change such as antiretroviral adherence and retention in care. OBJECTIVE: This study aimed to develop a theory-driven talking avatar-like embodied agent mobile phone intervention guided by the information-motivation-behavioral skills model to promote HIV medication adherence and retention in care in young African American men who have sex with men (MSM). METHODS: We performed 5 iterative focus groups in Chicago with HIV-positive African American MSM aged 18-34 years to inform the ongoing development of a mobile phone app. Participants for the focus groups were recruited from 4 University of Illinois at Chicago Community Outreach Intervention Project sites located in different high HIV incidence areas of the city and the University of Illinois at Chicago HIV clinic using fliers and word of mouth. The focus group data analysis included developing an ongoing list of priorities for app changes and discussion between two of the investigators based on the project timeline, resources, and to what extent they served the app's objectives. RESULTS: In this study, 16 men participated, including 3 who participated in two groups. The acceptability for an embodied agent app was universal in all 5 focus groups. The app included the embodied agent response to questions and antiretroviral regimen information, adherence tracking, CD4 count and viral load tracking, motivational spoken messages, and customizability. Concerns that were identified and responded to in the development process included privacy, stigma, avoiding the harsh or commanding tone of voice, avoiding negative motivational statements, and making reminder functions for a variety of health care interactions. CONCLUSIONS: An avatar-like embodied agent mHealth approach was acceptable to young HIV-positive African American MSM. Its relational nature may make it an effective method of informing, motivating, and promoting health behavioral skills. Furthermore, the app's ease of access, stigma-free environment, and audiovisual format may help overcome some adherence barriers reported in this population.

Adherence to highly active antiretroviral therapy in Hyderabad, India: barriers, facilitators and identification of target groups.

We assessed the barriers and facilitators to highly active antiretroviral therapy adherence and determined their prevalence among HIV/AIDS patients in Hyderabad, India. We conducted a cross-sectional study among HIV-infected adults prescribed highly active antiretroviral therapy and receiving care from nine clinics. Depression was screened using Patient Health Questionnaire 9 and facilitators of HIV medication adherence were assessed using an 11-item scale which yielded a total positive attitude to disease score. Prevalence ratios of non-adherence between different categories of potential risk factors were calculated. We compared mean 'facilitators to adherence' scores between the adherent and non-adherent population. Multivariable Poisson regression with robust variance was used to identify independent risk factors. Among the 211 respondents, nearly 20% were non-adherent, approximately 8% had either moderately severe or severe depression and mean score for combined facilitators to medication adherence was 33.35 (±7.88) out of a possible 44 points. Factors significantly associated with non-adherence included older age, female sex worker, moderate-to-severe depression and the combined facilitators to medication adherence score. These data from a broad range of clinical settings in Hyderabad reveal that key groups to focus on for adherence intervention are female sex workers, older persons and those with depression.

An Outbreak of Chikungunya in Rural Bangladesh, 2011.

BACKGROUND: The first identified Chikungunya outbreak occurred in Bangladesh in 2008. In late October 2011, a local health official from Dohar Sub-district, Dhaka District, reported an outbreak of undiagnosed fever and joint pain. We investigated the outbreak to confirm the etiology, describe the clinical presentation, and identify associated vectors. METHODOLOGY: During November 2-21, 2011, we conducted house-to-house surveys to identify suspected cases, defined as any inhabitant of Char Kushai village with fever followed by joint pain in the extremities with onset since August 15, 2011. We collected blood specimens and clinical histories from self-selected suspected cases using a structured questionnaire. Blood samples were tested for IgM antibodies against Chikungunya virus. The village was divided into nine segments and we collected mosquito larvae from water containers in seven randomly selected houses in each segment. We calculated the Breteau index for the village and identified the mosquito species. RESULTS: The attack rate was 29% (1105/3840) and 29% of households surveyed had at least one suspected case: 15% had ≥3. The attack rate was 38% (606/1589) in adult women and 25% in adult men (320/1287). Among the 1105 suspected case-patients, 245 self-selected for testing and 80% of those (196/245) had IgM antibodies. In addition to fever and joint pain, 76% (148/196) of confirmed cases had rash and 38%(75/196) had long-lasting joint pain. The village Breteau index was 35 per 100 and 89%(449/504) of hatched mosquitoes were Aedes albopictus. CONCLUSION: The evidence suggests that this outbreak was due to Chikungunya. The high attack rate suggests that the infection was new to this area, and the increased risk among adult women suggests that risk of transmission may have been higher around households. Chikungunya is an emerging infection in Bangladesh and current surveillance and prevention strategies are insufficient to mount an effective public health response.

The descriptive epidemiology of yersiniosis: a multistate study, 2005-2011.

OBJECTIVES: Yersiniosis, a foodborne infection of zoonotic origin caused by the bacteria Yersinia enterocolitica and Yersinia pseudotuberculosis, is a reportable disease in 38 states. Both sporadic and foodborne outbreaks of yersiniosis have been reported in the U.S., with annual occurrence of an estimated 98,000 episodes of illness, 533 hospitalizations, and 29 deaths. We analyzed surveillance data from nine non-FoodNet-participating U.S. states during the period 2005-2011 to describe the epidemiology of this disease. METHODS: As part of a passive surveillance system, laboratory-confirmed cases of yersiniosis were reported to state health departments in Arizona, Illinois, Michigan, Missouri, Nebraska, North Carolina, South Carolina, Washington, and Wisconsin. We calculated overall, age-, and race-specific annual incidence rates per 100,000 population using 2010 Census data as the denominator. We used Poisson regression to examine seasonal variation and annual incidence trends by race, age group, and overall. RESULTS: The average annual incidence of yersiniosis was 0.16 cases per 100,000 population during 2005-2011. We observed a statistically significant decreasing annual trend of yersiniosis incidence among African Americans <5 years of age (p<0.01), whereas white people aged 19-64 years (p=0.08) and Hispanic people (p=0.05) had an overall increasing annual incidence of yersiniosis. We observed higher incidence during October-December (p<0.01) and January-March (p=0.03) quarters among African Americans, whereas white people had a higher incidence during April-June (p=0.05). CONCLUSION: This multistate analysis revealed differences in the epidemiology of yersiniosis by race/ethnicity that may be useful for future research and prevention efforts. While this study was consistent with the FoodNet report in recognizing the high and declining incidence among African American children and winter seasonality among African Americans, our study also identified April-June seasonality among the white population.

Risk practices for animal and human anthrax in Bangladesh: an exploratory study.

INTRODUCTION: From August 2009 to October 2010, International Centre for Diarrheal Disease Research, Bangladesh and the Institute of Epidemiology, Disease Control and Research together investigated 14 outbreaks of anthrax which included 140 animal and 273 human cases in 14 anthrax-affected villages. Our investigation objectives were to explore the context in which these outbreaks occurred, including livestock rearing practices, human handling of sick and dead animals, and the anthrax vaccination program. METHODS: Field anthropologists used qualitative data-collection tools, including 15 hours of unstructured observations, 11 key informant interviews, 32 open-ended interviews, and 6 group discussions in 5 anthrax-affected villages. RESULTS: Each cattle owner in the affected communities raised a median of six ruminants on their household premises. The ruminants were often grazed in pastures and fed supplementary rice straw, green grass, water hyacinth, rice husk, wheat bran, and oil cake; lactating cows were given dicalcium phosphate. Cattle represented a major financial investment. Since Islamic law forbids eating animals that die from natural causes, when anthrax-infected cattle were moribund, farmers often slaughtered them on the household premises while they were still alive so that the meat could be eaten. Farmers ate the meat and sold it to neighbors. Skinners removed and sold the hides from discarded carcasses. Farmers discarded the carcasses and slaughtering waste into ditches, bodies of water, or open fields. Cattle in the affected communities did not receive routine anthrax vaccine due to low production, poor distribution, and limited staffing for vaccination. CONCLUSION: Slaughtering anthrax-infected animals and disposing of butchering waste and carcasses in environments where ruminants live and graze, combined with limited vaccination, provided a context that permitted repeated anthrax outbreaks in animals and humans. Because of strong financial incentives, slaughtering moribund animals and discarding carcasses and waste products will likely continue. Long-term vaccination coverage for at-risk animal populations may reduce anthrax infection.
