Abstract
Patients advise their peers on how to cope with their illness in daily life on online support groups. To date, no efforts have been made to automatically extract recommended coping strategies from online patient discussion groups. We introduce this new task, which poses a number of challenges including complex, long entities, a large long-tailed label space, and cross-document relations. We present an initial ontology for coping strategies as a starting point for future research on coping strategies, and the first end-to-end pipeline for extracting coping strategies for side effects. We also compared two possible computational solutions for this novel and highly challenging task; multi-label classification and named entity recognition (NER) with entity linking (EL). We evaluated our methods on the discussion forum from the Facebook group of the worldwide patient support organization 'GIST support international' (GSI); GIST support international donated the data to us. We found that coping strategy extraction is difficult and both methods attain limited performance (measured with F1 score) on held out test sets; multi-label classification outperforms NER+EL (F1=0.220 vs F1=0.155). An inspection of the multi-label classification output revealed that for some of the incorrect predictions, the reference label is close to the predicted label in the ontology (e.g. the predicted label 'juice' instead of the more specific reference label 'grapefruit juice'). Performance increased to F1=0.498 when we evaluated at a coarser level of the ontology. We conclude that our pipeline can be used in a semi-automatic setting, in interaction with domain experts to discover coping strategies for side effects from a patient forum. For example, we found that patients recommend ginger tea for nausea and magnesium and potassium supplements for cramps. This information can be used as input for patient surveys or clinical studies.

Impact of HIV infection and integrase strand transfer inhibitors-based treatment on the gut virome. Sci Rep 2022; 12:21658. [PMID: 36522388 PMCID: PMC9755154 DOI: 10.1038/s41598-022-25979-5] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Accepted: 12/07/2022] [Indexed: 12/23/2022] Open
Abstract
Viruses are the most abundant components of the human gut microbiome with a significant impact on health and disease. The effects of human immunodeficiency virus (HIV) infection on gut virome has been scarcely analysed. Several studies suggested that integrase strand transfers inhibitors (INSTIs) are associated with a healthier gut. Thus, the objective of this work was to evaluate the effects of HIV infection and INSTIs on gut virome composition. 26 non-HIV-infected volunteers, 15 naive HIV-infected patients and 15 INSTIs-treated HIV-infected patients were recruited and their gut virome composition was analysed using shotgun sequencing. Bacteriophages were the most abundant and diverse viruses present in gut. HIV infection was accompanied by a decrease in phage richness which was reverted after INSTIs-based treatment. β-diversity of phages revealed that samples from HIV-infected patients clustered separately from those belonging to the control group. Differential abundant analysis showed an increase in phages belonging to Caudoviricetes class in the naive group and a decrease of Malgrandaviricetes class phages in the INSTIs-treated group compared to the control group. Besides, it was observed that INSTIs-based treatment was not able to reverse the increase of lysogenic phages associated with HIV infection or to modify the decrease observed on the relative abundance of Proteobacteria-infecting phages. Our study describes for the first time the impact of HIV and INSTIs on gut virome and demonstrates that INSTIs-based treatments are able to partially restore gut dysbiosis at the viral level, which opens several opportunities for new studies focused on microbiota-based therapies.

[PMID: 36222289 PMCID: PMC9782451 DOI: 10.2196/39015] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 08/03/2022] [Accepted: 10/11/2022] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND The management of people living with HIV and AIDS is multidimensional and complex. Using patient-reported outcome measures (PROMs) has been increasingly recognized to be the key factor for providing patient-centered health care to meet the lifelong needs of people living with HIV and AIDS from diagnosis to death. However, there is currently no consensus on a PROM recommended for health care providers and researchers to assess health outcomes in people living with HIV and AIDS. OBJECTIVE The purpose of this systematic review was to summarize and categorize the available validated HIV-specific PROMs in adults living with HIV and AIDS and to assess these PROMs using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) methodology. METHODS This systematic review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search of 3 recommended databases (PubMed, Embase, and PsychINFO) was conducted on January 15, 2021. Studies were included if they assessed any psychometric property of HIV-specific PROMs in adults living with HIV and AIDS and met the eligibility criteria. The PROMs were assessed for 9 psychometric properties, evaluated in each included study following the COSMIN methodology by assessing the following: the methodological quality assessed using the COSMIN risk of bias checklist; overall rating of results; level of evidence assessed using the modified Grading of Recommendations, Assessment, Development, and Evaluation approach; and level of recommendation. RESULTS A total of 88 PROMs classified into 8 categories, assessing the psychometric properties of PROMs for adults living with HIV and AIDS, were identified in 152 studies including 79,213 people living with HIV and AIDS. The psychometric properties of most included PROMs were rated with insufficient evidence. The PROMs that received class A recommendation were the Poz Quality of Life, HIV Symptom Index or Symptoms Distress Module of the Adult AIDS Clinical Trial Group, and People Living with HIV Resilience Scale. In addition, because of a lack of evidence, recommendations regarding use could not be made for most of the remaining assessed PROMs (received class B recommendation). CONCLUSIONS This systematic review recommends 3 PROMs to assess health outcomes in adults living with HIV and AIDS. However, all these PROMs have some shortcomings. In addition, most of the included PROMs do not have sufficient evidence for assessing their psychometric properties and require a more comprehensive validation of the psychometric properties in the future to provide more scientific evidence. Thus, our findings may provide a reference for the selection of high-quality HIV-specific PROMs by health care providers and researchers for clinical practice and research.

Integrase Inhibitors Partially Restore Bacterial Translocation, Inflammation and Gut Permeability Induced by HIV Infection: Impact on Gut Microbiota. Infect Dis Ther 2022; 11:1541-1557. [PMID: 35618952 PMCID: PMC9334516 DOI: 10.1007/s40121-022-00654-4] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 05/04/2022] [Indexed: 11/30/2022] Open
Abstract
Introduction Human immunodeficiency virus (HIV) infection can be considered a chronic disease thanks to the extended use of antiretroviral treatment (ART). In this context, low-grade chronic inflammation related to gut microbiota (GM) dysbiosis and bacterial translocation (BT) among other factors has been observed despite the use of ART. In addition, different ART regimens have demonstrated differential impacts on GM. However, the role of novel integrase strand transfer inhibitors (INSTIs) has not been investigated yet. The aim of this study was to analyse the effects of INSTIs in first-line of treatment on markers of BT, inflammation, cardiovascular risk, gut permeability and GM composition and derived short-chain fatty acids. Methods Twenty-six non-HIV-infected volunteers and 30 HIV-infected patients (15 naïve and 15 under INSTIs regimen) were recruited. Blood samples were extracted to analyse biochemical parameters and markers of BT, inflammation, cardiovascular risk, gut permeability and bacterial metabolism. GM composition was analysed using 16S rRNA gene sequencing. Results Our results showed that HIV infection increased BT, inflammation, cardiovascular risk and gut permeability, whereas INSTIs counteracted these effects. Regarding GM, the reduction in bacterial richness induced by HIV infection was restored by INSTIs. Beta diversity revealed that HIV-infected people were separated from the control group independently of treatment. Conclusions Current antiretroviral regimens based on INSTIs are able to reverse the impact of HIV infection on BT, systemic inflammation, gut permeability and bacterial diversity/richness, reaching similar levels to those observed in an uninfected/control population. These results suggest a protective role of INSTIs in disease progression, subsequent immune activation and in the development of future age-related complications such as cardiovascular events.

Development of In Situ Self-Assembly Nanoparticles to Encapsulate Lopinavir and Ritonavir for Long-Acting Subcutaneous Injection. Pharmaceutics 2021; 13:pharmaceutics13060904. [PMID: 34207272 PMCID: PMC8235542 DOI: 10.3390/pharmaceutics13060904] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 05/21/2021] [Accepted: 05/24/2021] [Indexed: 11/17/2022] Open
Abstract
Most antiretroviral medications for human immunodeficiency virus treatment and prevention require high levels of patient adherence, such that medications need to be administered daily without missing doses. Here, a long-acting subcutaneous injection of lopinavir (LPV) in combination with ritonavir (RTV) using in situ self-assembly nanoparticles (ISNPs) was developed to potentially overcome adherence barriers. The ISNP approach can improve the pharmacokinetic profiles of the drugs. The ISNPs were characterized in terms of particle size, drug entrapment efficiency, drug loading, in vitro release study, and in vivo pharmacokinetic study. LPV/RTV ISNPs were 167.8 nm in size, with a polydispersity index of less than 0.35. The entrapment efficiency was over 98% for both LPV and RTV, with drug loadings of 25% LPV and 6.3% RTV. A slow release rate of LPV was observed at about 20% on day 5, followed by a sustained release beyond 14 days. RTV released faster than LPV in the first 5 days and slower than LPV thereafter. LPV trough concentration remained above 160 ng/mL and RTV trough concentration was above 50 ng/mL after 6 days with one subcutaneous injection. Overall, the ISNP-based LPV/RTV injection showed sustained release profiles in both in vitro and in vivo studies.

Impact of long-term antiretroviral therapy on gut and oral microbiotas in HIV-1-infected patients. Sci Rep 2021; 11:960.

Abstract
In HIV-1-infected patients, antiretroviral therapy (ART) is a key factor that may impact commensal microbiota and cause the emergence of side effects. However, it is not fully understood how long-term ART regimens have diverse impacts on the microbial compositions over time. Here, we performed 16S ribosomal RNA gene sequencing of the fecal and salivary microbiomes in patients under different long-term ART. We found that ART, especially conventional nucleotide/nucleoside reverse transcriptase inhibitor (NRTI)-based ART, has remarkable impacts on fecal microbial diversity: decreased α-diversity and increased ß-diversity over time. In contrast, dynamic diversity changes in the salivary microbiome were not observed. Comparative analysis of bacterial genus compositions showed a propensity for Prevotella-enriched and Bacteroides-poor gut microbiotas in patients with ART over time. In addition, we observed a gradual reduction in Bacteroides but drastic increases in Succinivibrio and/or Megasphaera under conventional ART. These results suggest that ART, especially NRTI-based ART, has more suppressive impacts on microbiota composition and diversity in the gut than in the mouth, which potentially causes intestinal dysbiosis in patients. Therefore, NRTI-sparing ART, especially integrase strand transfer inhibitor (INSTI)- and/or non-nucleotide reverse transcriptase inhibitor (NNRTI)-containing regimens, might alleviate the burden of intestinal dysbiosis in HIV-1-infected patients under long-term ART.

Abstract
PURPOSE Research into causality assessment tools enabling patients to assess suspected adverse drug reactions (ADRs) is limited. Supporting patients with tools could improve their confidence in discussions with health professionals and encourage reporting of suspected ADRs to regulators. This study describes development and preliminary validation of an instrument: Side Effect Patient ASsessment Tool (SE-PAST). METHODS SE-PAST was developed from survey and interview data involving patients experiencing suspected ADRs. It included 10 statements enabling causality assessment, covering timing, additional information sources, and experiences, with four options: yes/no/don't know/not applicable. Scoring and weighting resulted in four categories of causal association: highly probable, probable, possible, unlikely. Validation involved obtaining feedback from 31 individuals experiencing an ADR. Further validation involved online distribution through patient support groups and comparison of reported symptoms to known ADRs. RESULTS Validators found SE-PAST easy to read (31), to understand (27), and to complete (29). A total of 294 respondents completed SE-PAST online, with 98% completing eight or more causality assessment statements. Symptoms were categorised as highly probable (46; 16%), probable (80; 62%), possible (44; 15%), and unlikely (21; 7%). A total of 221 respondents identified one suspected medicine, with 95% of these reporting at least one symptom known to be an ADR. Of 227 providing feedback, 139 (61%) found SE-PAST useful, 160 (71%) felt motivated to discuss their experience with a health professional, and 136 (60%) were encouraged to report to the regulator. CONCLUSION SE-PAST was easily completed and understood by people experiencing suspected ADRs and could be useful in encouraging patient reporting to health professionals and agencies.

Abstract
Objectives An aging UK population and multi-morbidity means patients are receiving an increasing number of medicines. This can lead to greater risk of unintended side effects. The aim of this study was to increase understanding of how people identify and manage side effects from their medicines. Design A qualitative interview study with patients who had experienced side effects, recruited from community pharmacies. Methods This study examined patients’ experiences of side effects and the impact of these effects on their daily life. Fifteen participants were interviewed – 10 females and 5 males, with ages that ranged between 25 and 80 years, using different types and numbers of medicines. Results Thematic analysis revealed six themes: side effect experience, identification, adherence, information use, coping and body awareness. Participants described a wide range of physical and psychological symptoms which had both explicit and implicit impact on their lives. A system of identification based on constructed cognitive processes was common across participants. A variety of strategies were used by participants to cope with their side effects which included information seeking, social support seeking and non-adherent behaviours. Conclusions Psychological factors, such as medication beliefs, symptom interpretation and body awareness, contribute to cognitive and behavioural processes used to identify and manage side effects. These processes can have significant impacts on an individual’s decisions about adherence.

Coping Strategies for Adverse Effects of Antiretroviral Therapy among Adult HIV Patients Attending University of Gondar Referral Hospital, Gondar, Northwest Ethiopia: A Cross-Sectional Study. AIDS Res Treat 2018; 2018:1879198. [PMID: 30631595 PMCID: PMC6304486 DOI: 10.1155/2018/1879198] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2018] [Revised: 09/30/2018] [Accepted: 11/19/2018] [Indexed: 11/17/2022] Open
Abstract
Background Adverse effects from antiretroviral therapy (ART) have an impact on quality of life and medication adherence. There is no clear understanding of how people manage the adverse effects of ART. The individual taking medications which cause serious adverse effects may choose to stop or reduce the medications to relieve the adverse effects. Hence, this study was aimed at assessing coping strategies for adverse effects of ART among adult human immunodeficiency virus (HIV) patients. Methods A cross-sectional study was conducted at HIV clinic of University of Gondar Referral Hospital (UoGRH). A total of 394 study participants were recruited by systematic random sampling. Data were collected through interviewing patients. Data were entered to Epi-Info 3.5.4 and analyzed using SPSS-20.0. Descriptive statistics were used to summarize patient's sociodemographic data and the adverse effects of their ART regimen. Binary and multivariate logistic regressions were used to investigate the potential predictors of nonadherence coping strategies. Results The majorities of study participants were females (66%) and aged between 35 and 44 years (38.1%). The major adverse effects reported by the participants were headache (48.2%) followed by fatigability (18%) and loss of appetite (17.5%). Coping strategies used by HIV patients for adverse effect of ART were positive emotion coping strategy (91.1%), social support seeking (76.6%), taking other medications (76.6%), information seeking (48.7%), and nonadherence (35.5%). Younger age (AOR = 29.54, 95% CI = 2.49-35.25, p = 0.007), low level of education (AOR = 5.70, 95% CI = 2.16-15.05, p < 0.001), and living far from the health institution (AOR = 2.68, 95% CI = 1.29-5.57, p = 0.008) were associated with nonadherence coping strategy to relieve the adverse effects of ART. Conclusion The present study revealed that positive emotion coping was the most commonly used strategy. Age, level of education, and distance from health institution were the predictors of nonadherence coping strategy.

Abstract
BACKGROUND Prompt management of side effects is critical to supporting adherence to antiretroviral (ARV) medication. OBJECTIVE This study examines the impact of presenting side effect information using simple text combined with pictograms on sustained knowledge of ARV side effects over three months. METHOD Previously designed side effect pictograms, combined with simple text, were incorporated into a side effects panel within an ARV information leaflet. In a randomised controlled study, 116 limited literacy HIV patients taking ARVs were randomly allocated to either control (standard care) or intervention groups (standard care plus illustrated information). Side effect knowledge was assessed at baseline, and intervention patients received the illustrated leaflet. Knowledge was re-tested at one and three months. Interpretation of side effect pictograms was evaluated at one month. RESULTS In intervention patients, mean side effect knowledge increased from 45.9% (baseline) to 95.7% (three months; p<0.0001), and pictogram interpretation was good. Knowledge did not change significantly in the control group. All found the pictograms clear and useful, and endorsed their routine use. CONCLUSIONS Providing patients with simple written information containing pictograms on ARV side effects significantly improved side effect knowledge, sustained over time, in limited literacy, rural South African HIV patients.

Abstract
HIV treatment depends on high-levels of antiretroviral therapy (ART) adherence, which is severely impeded by poverty. Men and women living with HIV infection (N = 92) completed computerized interviews of demographic and health characteristics, poverty markers, stressful life events, and life chaos, as well as unannounced pill counts to determine prospective medication adherence and medical record chart abstractions for HIV viral load. Poverty markers were associated with both stressors and chaos, and the direct effects of all three factors predicted ART non-adherence. The multiple mediation model showed that accounting for stressors and chaos resulted in a non-significant association between poverty markers and ART adherence. The indirect effect of poverty markers on adherence through life chaos was significant, whereas the indirect effect of poverty markers on adherence through stressors was not significant. Factors that render HIV-related stress and create chaos offer intervention targets that are more amenable to change than poverty itself.

Abstract
OBJECTIVES Analyze and synthesize the research evidence to understand the reproductive decisions made by women living with HIV from the beginning of the epidemic to the present. Evaluate the barriers and the facilitators for reproductive decision-making. Identify areas of strength, improvement, and those requiring further research. DESIGN AND DATA SOURCES Systematic review following the PRISMA guideline. PubMed, CINAHL, PsycINFO, Cochrane Library, SocINDEX, Embase, and Scopus databases were searched from 1985 to 2016 using the following Keywords: HIV, AIDS, pregnancy, reproduction, and decision-making. STUDY SELECTION A total of 42 research papers were included in this review. Initially, 1563 papers were identified for the review by database (n=1544) and hand (n=19) searches. With three review levels, 1521 papers were excluded (title review, n=1272; abstract review, n=136; and full paper review, n=113). Studies published in English in peer-reviewed journals using both quantitative and qualitative methods and addressing reproductive decisions in women living with HIV were included. Thirdly, inclusion eligibility was assessed by title, abstract, and full text. REVIEW METHODS Random allocation conducted by the primary researcher assigned an equal number of papers to each researcher for review, including detailed instructions with an abstraction form. Discrepancies were resolved by two researchers. Research quality was assessed using the NCHBL Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies, the Critical Appraisal Skills Programme for the qualitative studies and its version for systematic reviews RESULTS: The review included 42 papers, both quantitative (n=24) and qualitative methods (n=14). Most studies were completed by physicians (n=16) or nurses (n=15). More than two-thirds of the studies were performed in urban settings with predominantly African-American women (n=27). Eight factors were identified as influencing the reproductive decision-making process in women living with HIV: 'Socio-demographic, Health status and Pregnancy', 'Religion and spirituality', 'Beliefs and Attitudes about Antiretroviral Therapy', 'Healthcare providers', 'Significant others', 'Motherhood and fulfillment', 'Fear of perinatal infection and infection of partner(s)', 'Birth control and pregnancy management'. CONCLUSIONS Health care providers are not providing patient-centered care by applying scientific evidence to their practice when advising women with HIV in making reproductive decisions. Despite the strong evidence indicating pregnancy for women with HIV results in a safe birthing trajectory, one not likely to jeopardize the health of the either the mother or fetus, providers continue to recommend the women with HIV avoid pregnancy and neglect to invite partners to participate in the discussion.

Abstract
BACKGROUND Individuals with HIV have a high prevalence of physical and psychological symptoms throughout their disease course. Despite the clinical and public health implications of unresolved pain and symptoms, little is known about the effect of anti-retroviral therapy (ART) on these outcomes. This study aimed to assess the impact on symptom burden for the year after ART initiation in individuals with a CD4 count <200 cells/uL in Uganda. METHODS HIV-infected, ART-naıve adults referred from voluntary testing and counseling services in rural Uganda for enrollment into a randomized controlled trial to test fluconazole as primary prophylaxis against cryptococcal disease were invited to complete the Memorial Symptom Assessment Scale-Short Form (MSAS-SF) prior to commencing ART and at two subsequent follow up visits. This tool measures self-reported 7-day period prevalence and associated burden of physical and psychological symptoms. Changes in the total number of symptoms and distress indices with time on ART and trial arm were investigated through fitting Linear Mixed Models for repeated measures. RESULTS During the first year of ART initiation the prevalence of most individual symptoms remained constant. The notable exceptions which improved after commencing ART are as follow; prevalence of pain (prevalence changed from 79% to 60%), weight loss (67% to 31%), lack of appetite (46% to 28%), feeling sad (52% to 25%) and difficulty sleeping (35% to 23%). The total number of symptoms and distress indices reduced after treatment commenced. Of concern was that half or more study participants remained with symptoms of pain (60%), itching (57%), skin changes (53%) and numbness in hands and feet (52%) after starting ART. Sixteen symptoms remained with a burden of 25% or more. CONCLUSION Despite the beneficial effect of ART on reducing symptoms, some patients continue to experience a high symptom burden. It is essential that HIV services in sub-Saharan Africa integrate management of symptoms into their programmes. TRIAL REGISTRATION CRYPTOPRO [ISRCTN 76481529 ], November 2004.

Abstract
Although third-line antiretroviral therapy (ART) is available in South Africa's public sector, its cost is substantially higher than first and second line. Identifying risk factors for failure on second-line treatment remains crucial to reduce the need for third-line drugs. We conducted a case-control study including 194 adult patients (≥18 years; 70 cases and 124 controls) who initiated second-line ART in Johannesburg, South Africa. Unconditional logistic regression was used to assess predictors of virologic failure (defined as 2 consecutive viral load measures ≥1000 copies/mL, ≥3 months after switching to second line). Variables included a social instability index, ART adherence, self-reported as well as diagnosed adverse drug reactions (ADRs), HIV disclosure, depression, and factors affecting access to HIV clinics. Overall 60.0% of cases and 54.0% of controls were female. Mean ages of cases and controls were 41.8 ± 9.6 and 43.3 ± 8.0, respectively. Virologic failure was predicted by ART adherence <90% [odds ratio (OR) 4.7; 95% confidence interval (95% CI): 2.1-10.5], younger age (<40 years of age; OR 0.6; 95% CI: 0.3-1.1), high social instability (OR 3.8; 95% CI: 1.30-11.5), self-reported ADR (OR 1.9; 95% CI: 1.0-3.5), disclosure to friends/colleagues rather than partner/relatives (OR 3.4; 95% CI: 1.3-9.1), and medium/high depression compared to low/no depression (OR 4.4; 95% CI: 1.5-13.4). Our results suggest complex socioeconomic factors contributing to risk of virologic failure, possibly by impacting ART adherence, among patients on second-line therapy in South Africa. Identifying patients with possible indicators of nonadherence could facilitate targeted interventions to reduce the risk of second-line treatment failure and mitigate the demand for third-line regimens.

Abstract
OBJECTIVE Taking adjuvant hormonal therapy for 5-10 years is recommended to prevent breast cancer recurrence in those with oestrogen positive disease. Despite proven clinical efficacy many women do not take their hormonal therapy as prescribed. This study reports the development and initial validation of a questionnaire measuring the behavioural determinants of hormonal therapy medication taking behaviour (MTB) based on the theoretical domains framework (TDF). DESIGN Women with Stage I-III breast cancer (N = 223) completed the questionnaire based on the TDF. The TDF is an integrative framework consisting of 14 domains of behaviour change determinants to inform intervention design. MAIN OUTCOME MEASURES Items were developed from previous research, in-depth patient interviews and consultation with health professionals. Confirmatory factor analysis (CFA) was undertaken to generate the model of best fit. RESULTS The final questionnaire consisted of eight domains and CFA produced a reasonable fit (χ2(810) = 942, p < .001; RMSEA = .03; CFI = .93 and WRMR = .91) as well as internal consistency (r = .16 to .64). There were adequate levels of discriminant validity for the majority of the domains. CONCLUSIONS A TDF-based measure of the behavioural determinants of MTB was developed. Further research is needed to confirm the reliability and validity of this measure.

Abstract
The side effects of antiretroviral (ARV) medications negatively impact patients' quality of life and adherence to treatment. This study describes the burden of side effects from ARV treatment as experienced by a sample of HIV/AIDS patients and identifies the personal strategies they used to cope with the side effects. A total of 166 participants were recruited from a non-governmental HIV/AIDS clinic in Entebbe, Uganda. Most of the participants (76%) were females and the mean age of the sample was 38 years. Although the participants had taken ARV medications for an average period of nine months, a large proportion (76%) could not name the medications they were taking. The mean side-effects burden for the participants was five side effects. The most common adverse effects reported were tiredness, nightmares, mood swings, nausea, poor appetite, insomnia, vomiting and dizziness. The main strategies the patients used for coping with the side effects were those categorised under information-seeking, social-support seeking and positive-emotion-focused coping. However, 27% of the participants reported non-adherence to their ARV medications as a strategy to cope with the side effects. The findings show a significant relationship between the side-effects burden and a patient's age (r = 0.530, p ≤ 0.01) and level of education (r = 0.394, p ≤ 0.01). The findings indicate that in the short term after initiating ARV treatment most patients are able to cope with the high burden of side effects through appropriate strategies, but a sizable portion will fail to cope appropriately and thus resort to non-adherence. Clinicians should assist patients with continuous health education and counselling that focuses on appropriate strategies to cope with the side effects of ARVs in order to buffer the negative impact of HIV treatment on patients' adherence and quality of life.

Abstract
The side effects of antiretroviral (ARV) therapy are linked to altered quality of life and adherence. Poor adherence has also been associated with low health-literacy skills, with an uninformed patient more likely to make ARV-related decisions that compromise the efficacy of the treatment. Low literacy skills disempower patients in interactions with healthcare providers and preclude the use of existing written patient information materials, which are generally written at a high reading level. Visual images or pictograms used as a counselling tool or included in patient information leaflets have been shown to improve patients' knowledge, particularly in low-literate groups. The objective of this study was to design visuals or pictograms illustrating various ARV side effects and to evaluate them in a low-literate South African Xhosa population. Core images were generated either from a design workshop or from posed photos or images from textbooks. The research team worked closely with a graphic artist. Initial versions of the images were discussed and assessed in group discussions, and then modified and eventually evaluated quantitatively in individual interviews with 40 participants who each had a maximum of 10 years of schooling. The familiarity of the human body, its facial expressions, postures and actions contextualised the information and contributed to the participants' understanding. Visuals that were simple, had a clear central focus and reflected familiar body experiences (e.g. vomiting) were highly successful. The introduction of abstract elements (e.g. fever) and metaphorical images (e.g. nightmares) presented problems for interpretation, particularly to those with the lowest educational levels. We recommend that such visual images should be designed in collaboration with the target population and a graphic artist, taking cognisance of the audience's literacy skills and culture, and should employ a multistage iterative process of modification and evaluation.

Abstract
BACKGROUND Adverse drug events (ADEs) cause significant morbidity and mortality to patients. A brief questionnaire asking patients how they coped with such problems could be a useful tool for providing timely interventions. OBJECTIVE The aim of this study was to develop an adverse-event coping scale (AECS) to measure patients' coping responses to their ADE. METHODS Data were collected from subjects recruited from community pharmacies. Psychometric analyses based on item response theory (IRT) were performed to calibrate items and assess reliability. Convergent validity was evaluated by testing a priori formulated hypotheses about expected correlations between the coping scores and other related scales. RESULTS A total of 140 patients participated in this study by answering the developed items. Confirmatory factor analysis supported a one-dimensional item bank with 11 items. The developed scale was reliable with the reliability coefficient of 0.82. Coping scores were positively correlated with seriousness of the ADE and health literacy, but not coping self-efficacy. Overall, results suggest that the score reflects problem magnitude and coping effort rather than coping efficacy. CONCLUSION A high score on the AECS indicates an ADE serious enough to prompt a patient to invest substantial efforts to cope with it. The final AECS item bank and its short-form can help clinicians better understand their patients' ADE-coping efforts.

Abstract
Background Little is known about how people living with human immunodeficiency virus (HIV) experience malaria and the concomitant use of anti-malarial treatments with anti-retrovirals (ARVs). An understanding of how patients make sense of these experiences is important to consider in planning and supporting the clinical management and treatment for co-infected individuals. Methods A qualitative study was conducted in Tanzania alongside a clinical trial of concomitant treatment for HIV and malaria co-infection. Focus group discussions were held with people receiving treatment for HIV and/or malaria, and in-depth interviews with health workers responsible for HIV care and members of the clinical trial team. Data were analysed inductively to identify themes and develop theoretical narratives. Results Results suggest that people living with HIV perceived malaria to be more harmful to them due to their compromised immune status but saw the disease as unavoidable. For those enrolled in the clinical controlled study, taking anti-malarials together with ARVs was largely seen as unproblematic, with health workers’ advice and endorsement of concomitant drug taking influential in reported adherence. However, perceptions of drug strength appeared to compel some people not enrolled in the clinical study to take the drugs at separate times to avoid anticipated harm to the body. Conclusions Management of HIV and malaria concurrently often requires individuals to cross the domains of different disease programmes. In the context of a trial concerned with both diseases, patients experienced the support of clinicians in guiding and reassuring them about when and how to take drugs concomitantly. This points towards the need to continue to strive for integrated care for patients with HIV.

Abstract
The present study examined whether emotion dysregulation moderated the relations between depressive symptoms and HIV symptoms, HIV medication adherence due to medication side effects, avoidant coping, and distress tolerance among people living with HIV/AIDS (PLHA). Participants included 115 PLHA (16.8% female; Mage = 49.70, SD = 8.57). Results indicated that there was a significant interaction between depressive symptoms and emotion dysregulation in relation to HIV symptoms, HIV medication adherence due to medication side effects, avoidant coping, and distress tolerance. The form of the interaction indicated that PLHA experiencing higher depressive symptoms and higher levels of emotion dysregulation reported the highest levels of HIV symptoms and lowest levels of distress tolerance. Additionally, results indicated that at lower levels of depressive symptoms, very high levels of emotion dysregulation predicted higher rates of medication nonadherence, whereas at higher levels of depressive symptoms, very high levels of emotion dysregulation predicted the lowest rates of medication nonadherence. Moreover, those experiencing lower levels of depressive symptoms and higher levels of emotion dysregulation reported the greatest rates of avoidant coping. In total, the present results suggest a complex interplay between emotion dysregulation and depressive symptoms with regard to HIV symptoms, medication nonadherence, and self-regulatory processes (e.g., avoidant coping, distress tolerance) among PLHA.

Abstract
Maximizing HIV treatment adherence is critical in efforts to optimize health outcomes and to prevent further HIV transmission. The Balance Project intervention uses cognitive behavioral approaches to improve antiretroviral medication adherence through promoting adaptive coping with medication side effect and distress related to HIV. This 5-session intervention has been documented to prevent nonadherence among persons living with HIV who experience high levels of distress associated with their antiretroviral medication side effects. We describe the theoretical underpinnings of the intervention, provide details of the training and session protocols with a case example, and discuss implications for future applications of the intervention in both research and clinical settings.

Abstract
Introduction We report on the adherence experience of a group of people living with HIV on ART over six years in Uganda. Methods Between 2005 and 2009, we followed up 41 participants who were also part of a clinical trial comparing home and facility based delivery of ART in Jinja, eastern Uganda. We conducted qualitative in-depth interviews at enrolment, 3, 6, 18 and 30 months to capture experiences with adherence over time. In 2011 we returned to these participants to find out how they were fairing with long term adherence. We managed to retrace 24 participants and interviewed them about their experience. We thematically analysed the data and compared findings over time. Results Initially there were few barriers to adherence and many followed the adherence guidance closely. By year six, relaxation of these rules was noticeable although self-reported adherence continued to be high. Alcohol consumption was more common than before. Some relatives of the participants who had died claimed that some deaths were a result of alcohol. While participants reported that ART had allowed them to reclaim independence and return to work the changes in work and social routines created new challenges for adherence. Side effects like lipodystrophy were not only causing some stigma but for some tested their faith in the drugs. Many participants reported resumption of sexual lives but apart from those who selected same status partners, disclosure to new partners was minimal. Conclusion Good adherence practice to ART wanes over the long-term, and people who may have disclosed at initiation find it difficult to do so to new partners once they are healthy. Further adherence interventions and support with disclosure over the course of therapy may need to be considered. (Words: 283)

Abstract
PURPOSE The study assessed coping practices to HIV treatment side effects among HIV-infected patients receiving antiretroviral therapy (ART) in selected hospitals in Nigeria. METHODS In a cross-sectional study, Side Effects Coping (SECope) instrument was administered to 3650 HIV-infected patients receiving ART in 36 hospitals. Patients were provided pre-treatment information on side effects of antiretroviral drugs. Factor analysis was performed using principal components extraction with varimax rotation. Factors selected for rotation had eigenvalues >1. Mean scale scores above midpoint of 3.18 on five-point scale were regarded as positive coping practices and below as negative practices. Chi-Square was used for inferential statistics; P < 0.05 used to determine statistical significance. RESULTS Mean of SECope instrument return rates was 47.5% (95%CI, 37.1-57.9). Data from 2329 (63.8%) participants were analyzed: 63.1% females and 63.9% aged 25 to 44 years old. The mean SECope scale score (±SD) was 3.18 (±0.80); mean subscale scores (±SD) were 3.52 (±0.20) positive emotion focused coping, 2.82 (±0.18) information seeking, 2.57 (±0.30) social support seeking, 2.34 (±0.39) taking side effect medications, and 4.43 (±0.10) non-adherence. Five extracted factors accounted for 67.2% of cumulative variability. All items had very significant loadings of 0.50 or greater. All subscales except positive emotion focused coping were associated with age (p < 0.05). Non-adherence and information seeking subscales were associated with employment status (p < 0.05). Taking side effect medications was associated with educational status (p < 0.05). CONCLUSION The study reported positive coping practices in positive emotion focused coping and non-adherence subscales. Non-adherence as a coping strategy was not significant contrary to previous research finding.

Abstract
Background Human immunodeficiency virus (HIV) treatment side effects have a deleterious impact on treatment adherence, which is necessary to optimize treatment outcomes including morbidity and mortality. Purpose To examine the effect of the Balance Project intervention, a five-session, individually delivered HIV treatment side effects coping skills intervention on antiretroviral medication adherence. Methods HIV+ men and women (N = 249) on antiretroviral therapy (ART) with self-reported high levels of ART side effect distress were randomized to intervention or treatment as usual. The primary outcome was self-reported ART adherence as measured by a combined 3-day and 30-day adherence assessment. Results Intent-to-treat analyses revealed a significant difference in rates of nonadherence between intervention and control participants across the follow-up time points such that those in the intervention condition were less likely to report nonadherence. Secondary analyses revealed that intervention participants were more likely to seek information about side effects and social support in efforts to cope with side effects. Conclusions Interventions focusing on skills related to ART side-effects management show promise for improving ART adherence among persons experiencing high levels of perceived ART side effects.

Abstract
OBJECTIVES Within a trial of medical and surgical treatments for gastro-esophageal reflux disease (GORD), involving randomised arms and preference arms, we tested the applicability of the Beliefs about Medicines Questionnaire (BMQ) and developed and tested the validity of a new Beliefs about Surgery Questionnaire (BSQ). METHODS Patients with GORD (N = 43) were interviewed to elicit their beliefs about medical and surgical treatments. These contributed to the development of BSQ items. The BMQ and BSQ were completed by trial participants at baseline (randomised trial: N = 325; preference trial: N = 414). Factor analysis and discriminant function analysis were used to assess validity. RESULTS Principal components analysis (PCA) largely replicated the four-factor BMQ structure. PCA of the combined BMQ/BSQ yielded six factors explaining 54.5% variance. BSQ items loaded onto distinct factors, demonstrating divergence from BMQ. As predicted, BMQ/BSQ scores enabled correct classification of 78.5% of participants to medication and surgery groups in the preference trial (chi(2)(6) = 205.9, p < 0.001) but only 54.5% (no better than chance) in the randomised trial (chi(2)(6) = 9.4, p = 0.154). CONCLUSIONS The BSQ is a valid measure of perceptions about surgical treatments for GORD. With the BMQ, it provides information that may guide patients' choices about treatment. This measure may be applicable to other conditions.

Abstract
A control-theoretic approach to the problem of designing "low-side-effects" therapies for HIV patients based on highly active drugs is substantiated here. The evolution of side effects during treatment is modeled by an extra differential equation coupled to the dynamics of virions, healthy T-cells, and infected ones. The new equation reflects the dependence of collateral damages on the amount of each dose administered to the patient and on the evolution of the viral load detected by periodical blood analysis. The cost objective accounts for recommended bounds on healthy cells and virions, and also penalizes the appearance of collateral morbidities caused by the medication. The optimization problem is solved by a hybrid dynamic programming scheme that adhere to discrete-time observation and control actions, but by maintaining the continuous-time setup for predicting states and side effects. The resulting optimal strategies employ less drugs than those prescribed by previous optimization studies, but maintaining high doses at the beginning and the end of each period of six months. If an inverse discount rate is applied to favor early actions, and under a mild penalization of the final viral load, then the optimal doses are found to be high at the beginning and decrease afterward, thus causing an apparent stabilization of the main variables. But in this case, the final viral load turns higher than acceptable.
