Sociodemographic profile and predictors of outpatient clinic attendance among HIV-positive patients initiating antiretroviral therapy in Selangor, Malaysia

BACKGROUND

Inconsistent literature evidence suggests that sociodemographic, economic, and system- and patient-related factors are associated with clinic attendance among the HIV-positive population receiving antiretroviral therapy (ART) around the world. We examined the factors that predict outpatient clinic attendance among a cohort of HIV-positive patients initiating ART in Selangor, Malaysia.

PATIENTS AND METHODS

This cross-sectional study analyzed secondary data on outpatient clinic attendance and sociodemographic, economic, psychosocial, and patient-related factors among 242 adult Malaysian patients initiating ART in Selangor, Malaysia. Study cohort was enrolled in a parent randomized controlled trial (RCT) in Hospital Sungai Buloh Malaysia between January and December 2014, during which peer counseling, medication, and clinic appointment reminders were provided to the intervention group through short message service (SMS) and telephone calls for 24 consecutive weeks. Data on outpatient clinic attendance were extracted from the hospital electronic medical records system, while other patient-level data were extracted from pre-validated Adult AIDS Clinical Trial Group (AACTG) adherence questionnaires in which primary data were collected. Outpatient clinic attendance was categorized into binary outcome - regular attendee and defaulter categories - based on the number of missed scheduled outpatient clinic appointments within a 6-month period. Multivariate regression models were fitted to examine predictors of outpatient clinic attendance using SPSS version 22 and R software.

RESULTS

A total of 224 (93%) patients who completed 6-month assessment were included in the model. Out of those, 42 (18.7%) defaulted scheduled clinic attendance at least once. Missed appointments were significantly more prevalent among females (n=10, 37.0%), rural residents (n=10, 38.5%), and bisexual respondents (n=8, 47.1%). Multivariate binary logistic regression analysis showed that Indian ethnicity (adjusted odds ratio [AOR] =0.235; 95% CI [0.063-0.869]; P=0.030) and heterosexual orientation (AOR =4.199; 95% CI [1.040-16.957]; P=0.044) were significant predictors of outpatient clinic attendance among HIV-positive patients receiving ART in Malaysia.

CONCLUSION

Ethnicity and sexual orientation of Malaysian patients may play a significant role in their level of adherence to scheduled clinic appointments. These factors should be considered during collaborative adherence strategy planning at ART initiation.

Impact of intensive treatment and remission on health-related quality of life in early and established rheumatoid arthritis

Objectives

To establish if using intensive treatment to reduce synovitis and attain remission in active rheumatoid arthritis (RA) improves all aspects of health-related quality of life (HRQoL).

Methods

A secondary analysis of two randomised clinical trials (CARDERA and TACIT) was undertaken. CARDERA randomised 467 patients with early active RA to different disease-modifying antirheumatic drug (DMARD) regimens, including high-dose tapering corticosteroids. TACIT randomised 205 established patients with active RA to combination DMARDs (cDMARDs) or tumour necrosis factor-α inhibitors (TNFis). Short-Form 36 (SF-36) measured HRQoL across eight domains, generating physical (PCS) and mental (MCS) component summary scores. Linear regression evaluated 6-month intensive treatment impacts. Mean SF-36 scores, stratified by end point disease activity category, were compared with age/gender-matched population scores.

Results

In CARDERA, intensive corticosteroid treatment gave significantly greater improvements in PCS but not MCS scores relative to placebo. In TACIT, all eight SF-36 domains had improvements from baseline exceeding minimal clinically important differences with cDMARDs and TNFis. Significantly greater improvements with TNFi relative to cDMARDs were reported in PCS only (p=0.034), after adjusting for covariates. Remission provided the best SF-36 profiles, but scores in physical functioning, role physical and general health in both trials remained below normative values. Patient global assessment of disease activity had a greater association with HRQoL than other disease activity score (DAS28) components.

Conclusions

Intensive corticosteroid treatment in early RA improves physical but not mental health, relative to placebo. In established RA, cDMARDs and TNFi provide similar improvements in HRQoL. As remission optimises but fails to normalise HRQoL, a focus on treatment strategies targeting HRQoL is required.

Trial registration numbers

CARDERA was registered as ISRCTN 32484878. TACIT was registered as ISRCTN 37438295; pre-results.

Predictors of Fear Related to Childbirth among Iranian Primigravidae

<p>Fears related Pregnancy-and childbirth are common psychological concerns and the main reasons for requesting cesarean section (CS). The current study aimed at describing the association between fear of childbirth and social, demographic and psychological factors and examines the predictors of maternal fear in a 342 healthy primigravidae women with uncomplicated singleton pregnancies. In this cross-sectional study, the participants (n=342 primigravidae) was randomly selected in 12 health care centers in Iran. The data was obtained by valid and reliable self-administered questionnaires that included questions on socio-demographic, psychological characteristics (self esteem, perceived stress, quality of marital relationship, perceived social support), fear related to childbirth and childbirth and analyzed by SPSS19. All primigravidae reported some degree of fear, i.e., 48.2% presented severe fear, and 62.6% requested a CS because of childbirth-related fear. Age, employment, level of education and medical insurance were associated with fear related to childbirth, as well as plan of pregnancy, self esteem and perceived stress. In combination, HBM subscales and the psychosocial factors accounted for a significant 68% of the variability in fear related to childbirth, <em>R²</em>=0.68, adjusted <em>R²</em>=0.67, <em>F</em>(12, 326)<strong>=</strong>69.4, p&lt;0.001. Fears related to pregnancy and childbirth was frequently experienced by all low-risk primigravidae. Better strategies to address women’s psychological needs during pregnancy are necessary.</p>

First Evidence of Shape Coexistence in the ^{78}Ni Region: Intruder 0_{2}^{+} State in ^{80}Ge

The N=48 ^{80}Ge nucleus is studied by means of β-delayed electron-conversion spectroscopy at ALTO. The radioactive ^{80}Ga beam is produced through the isotope separation on line photofission technique and collected on a movable tape for the measurement of γ and e^{-} emission following β decay. An electric monopole E0 transition, which points to a 639(1) keV intruder 0_{2}^{+} state, is observed for the first time. This new state is lower than the 2_{1}^{+} level in ^{80}Ge, and provides evidence of shape coexistence close to one of the most neutron-rich doubly magic nuclei discovered so far, ^{78}Ni. This result is compared with theoretical estimates, helping to explain the role of monopole and quadrupole forces in the weakening of the N=50 gap at Z=32. The evolution of intruder 0_{2}^{+} states towards ^{78}Ni is discussed.

UPLC-MS/MS assay of 21-aminosteroid (lazaroid U74389G) for application in pharmacokinetic study

Lazaroids are potent inhibitors of lipid peroxidation, both in vitro and in vivo. Additionally, a member of the lazaroid family, U-74389G (LAZ) has been shown to have specific radio-protective and anti-proliferative effects. However, there is no quantitative analytical method developed for measuring the therapeutic levels of LAZ for the aforementioned effects. This article highlights the development and validation of a sensitive UPLC-MS/MS method for the quantification of LAZ, and its subsequent application in pharmacokinetic studies in rats with the lower limit of quantification (LLOQ) of 1.95 ng/mL. LAZ and internal standard diadzein (IS) were separated using ACQUITY UPLC(®) BEH C18 column. Gradient elution was used at a flow rate of 0.45 mL/min with mobile phases consisting of 0.1% formic acid in water and 0.1% formic in acetonitrile. LAZ (m/z 612→260) and IS (m/z 255→199) were detected by electrospray ionization (ESI) using multiple reaction monitoring (MRM) in a positive mode on QTRAP(®) 5500 System. The UPLC-MS/MS method was validated as per the US FDA Guidelines for Bio-analytical Validation. LAZ was extracted from rat plasma (100 μL) using protein precipitation by acetonitrile with mean recovery and matrix factor in range of 47.7-56.1%, and 85.6-89.4%, respectively. The calibration curve for LAZ was linear in the range of 1.95-250 ng/mL. The inter-day and intra-day accuracy and precision values for LLOQ, low, medium, high and very high concentration QC samples were within ±15%. LAZ was tested under different storage conditions, for short-term bench-top stability (1h and 3h at 25°C), long-term stability (1 month at -80°C), freeze-thaw cycle stability (1 cycle and 3 cycles) and stability of processed samples in auto-sampler (24h at 10°C) with stability values within ±15% range of nominal concentrations. The validated UPLC-MS/MS method was further applied to a pharmacokinetic study in rats after a single intravenous dose of LAZ at 5 mg/kg.

Prognostic value of trans-thoracic echocardiography in patients with acute stroke and atrial fibrillation: findings from the RAF study

Anticoagulant therapy is recommended for the secondary prevention of stroke in patients with atrial fibrillation (AF). T he identification of patients at high risk for early recurrence, which are potential candidates to prompt anticoagulation, is crucial to justify the risk of bleeding associated with early anticoagulant treatment. The aim of this study was to evaluate in patients with acute ischemic stroke and AF the association between findings at trans-thoracic echocardiography (TTE) and 90 days recurrence. In consecutive patients with acute ischemic stroke and AF, TTE was performed within 7 days from hospital admission. Study outcomes were recurrent ischemic cerebrovascular events (stroke or TIA) and systemic embolism. 854 patients (mean age 76.3 ± 9.5 years) underwent a TTE evaluation; 63 patients (7.4%) had at least a study outcome event. Left atrial thrombosis was present in 11 patients (1.3%) among whom 1 had recurrent ischemic event. Left atrial enlargement was present in 548 patients (64.2%) among whom 51 (9.3%) had recurrent ischemic events. The recurrence rate in the 197 patients with severe left atrial enlargement was 11.7%. On multivariate analysis, the presence of atrial enlargement (OR 2.13; 95% CI 1.06-4.29, p = 0.033) and CHA2DS2-VASc score (OR 1.22; 95% CI 1.04-1.45, p = 0.018, for each point increase) were correlated with ischemic recurrences. In patients with AF-associated acute stroke, left atrial enlargement is an independent marker of recurrent stroke and systemic embolism. The risk of recurrence is accounted for by severe atrial enlargement. TTE-detected left atrial thrombosis is relatively uncommon.

In vivo study and thermodynamic investigation of two lanthanum complexes, La(dpp)3 and La(XT), for the treatment of bone resorption disorders

Bone density diseases such as osteoporosis affect a significant number of people worldwide. Lanthanide ions are functional mimics of calcium ions, able to substitute for Ca2+ in the bone mineral component, hydroxyapatite (HAP). Bone undergoes a continuous remodelling cycle and lanthanides can affect this cycle, exerting a positive influence on bone mineral. We have been engaged in efforts to find new lanthanide containing complexes as active agents for treatment of these diseases and have identified two lead compounds, 3-hydroxy-1,2-dimethylpyridin-4(1H)-one (Hdpp) and a phosphinate-EDTA derivative, bis[[bis(carboxymethyl)amino]-methyl]phosphinate (H5XT). In this paper, we report in vivo data for the first time for the two lead compounds. The pharmacokinetics of La(dpp)3 suggest the complex is rapidly cleared from plasma. We demonstrate that La3+ accumulates in the bone following IV dose of either La(dpp)3 or La(XT) and we have investigated the influence of each chelating ligand on the incorporation of La3+ into HAP using ITC and HAP-binding studies.

HIV-infected People in Sudan Moving Toward Chronic Poverty: Possible Interventions

We sought to identify the socioeconomic impact on people living with HIV (PLWH) in Sudan. Focus group discussions were used to collect data and identify the most outstanding domains of HIV impact on PLWH and the survival mechanisms that may be common to a group of diverse HIV-infected persons (n = 30). The findings indicated that the most striking financial and social impacts were due to stigma associated with HIV in the conservative Sudanese society, which led to loss of work with all its consequences (e.g., children's education and health care expenses were affected). The socioeconomic impacts of HIV on infected populations are discussed, and suggestions for possible interventions to mitigate harmful impacts and stigma within the society, the workplace, and health care settings are highlighted. We concluded that HIV has intensified the existing problems of infected people, contributing to their vulnerability to poverty.

Testing comparison models of DASS-12 and its reliability among adolescents in Malaysia

OBJECTIVE

The 21-item Depression, Anxiety and Stress Scale (DASS-21) is frequently used in non-clinical research to measure mental health factors among adults. However, previous studies have concluded that the 21 items are not stable for utilization among the adolescent population. Thus, the aims of this study are to examine the structure of the factors and to report on the reliability of the refined version of the DASS that consists of 12 items.

METHOD

A total of 2850 students (aged 13 to 17 years old) from three major ethnic in Malaysia completed the DASS-21. The study was conducted at 10 randomly selected secondary schools in the northern state of Peninsular Malaysia. The study population comprised secondary school students (Forms 1, 2 and 4) from the selected schools.

RESULTS

Based on the results of the EFA stage, 12 items were included in a final CFA to test the fit of the model. Using maximum likelihood procedures to estimate the model, the selected fit indices indicated a close model fit (χ(2)=132.94, df=57, p=.000; CFI=.96; RMR=.02; RMSEA=.04). Moreover, significant loadings of all the unstandardized regression weights implied an acceptable convergent validity. Besides the convergent validity of the item, a discriminant validity of the subscales was also evident from the moderate latent factor inter-correlations, which ranged from .62 to .75. The subscale reliability was further estimated using Cronbach's alpha and the adequate reliability of the subscales was obtained (Total=76; Depression=.68; Anxiety=.53; Stress=.52).

CONCLUSION

The new version of the 12-item DASS for adolescents in Malaysia (DASS-12) is reliable and has a stable factor structure, and thus it is a useful instrument for distinguishing between depression, anxiety and stress.

Antiphospholipid (Hughes) syndrome: description of population and health-related quality of life (HRQoL) using the SF-36

Objective

Antiphospholipid (Hughes) syndrome (APS) affects mainly women 15 to 50 years of age and is responsible for approximately 20% of strokes in people <40 years. Little is known about the psychological burden of this long-term condition. We investigated HRQoL in APS.

Methods

We conducted a cross-sectional survey involving 270 members of the Hughes Syndrome Foundation worldwide. Data included HRQoL (SF-36), demographics, and APS-related self-reported major issues. Response rate was 60%.

Results

T-tests indicated significantly worse mean scores for seven of the eight domains of the SF-36 in secondary antiphospholipid syndrome (SAPS) compared to primary antiphospholipid syndrome (PAPS), e.g. bodily pain t(263) = 6.10 p < 0.001 except for mental health t(267) = 1.95 p = 0.053. PAPS appeared to be associated with poorer HRQoL in most mental health domains but overall better physical domains compared to systemic lupus erythematosus (SLE) alone. SAPS appeared to have a more adverse impact on HRQoL compared to PAPS and SLE. Major issues identified: pain and fatigue, lack of health care professional/public awareness, and medication unpredictability.

Conclusion

HRQoL in PAPS appears to be generally better than SLE and SAPS in physical domains, but poorer in mental domains. APS patients might need more social support in terms of information and awareness of the condition to improve their coping strategies.
