Influence of religion on healthcare professionals’ beliefs toward teenage sexual practices in Malaysia
Background: Teenagers are influenced by their surroundings, and this may also include their sexual behavior or societal responses to this type of behavior. It is important to understand the complexity of religious mandates and
sociocultural disapproval of premarital sex from the perspectives of healthcare professionals.
Methods: This qualitative study aimed to explore the influence of religion on healthcare professional’s beliefs toward providing sexual and reproductive health information and treatment. An interview topic guide was used in the in-depth interview of 32 healthcare professionals in several health clinics in Malaysia. The data were transcribed and entered into the NVivo 11 software. Thematic analysis was used to evaluate the data.
Results: The findings show that some healthcare professionals
positively incorporated Islamic beliefs into sexual health education session but excluded the contraception information.
This study also highlights the strategies used by healthcare professionals (discourse on risk, being selective, maintaining
their own honor) when providing sexual health services to teenagers. Conclusion: These findings revealed how religion
perpetuates a “moral” approach in the provision of sexual health services that potentially affects teenagers’ access to
healthcare
The strategies used by the school health team during the delivery of sexual health information to unmarried adolescents in Malaysia
Background: Adolescents’ sexual health is vital to overall health and well-being to achieve sustainable development goals. Yet, research on the strategies used by Malaysian school health teams regarding their experiences of providing sexual health information to adolescents is sparse. Objective: This study was conducted to explore the experiences of school health teams in
Malaysia who provide unmarried adolescents with sexual health information either during school health visits or at health clinics, with a particular interest in the strategies they use to educate these young people. Methods: This qualitative study used semi-structured interview data from twenty participants from four multidisciplinary school health teams. The participants included staff nurses,
medical officers, and family medicine specialists. The transcripts were analysed for common themes. Results: Four main themes were identified: discourse on risk, being selective, using scare
tactics and maintaining own honour. The findings indicate that the interactions between school health teams and unmarried adolescents were not always ‘adolescent friendly’. The school
health teams tended to use discourses of ‘risk’ or scare tactics to encourage abstinence in the adolescents they advised. Staff were also selective about the information they gave, prioritising notions of ‘maintaining honour’ over ‘safer sex’ messages.
Conclusion: This study revealed how school health teams perceived sexual health education to be about moral issues and social attitudes. Influenced by both culture and religion, the
sexual health services provided were underpinned by a ‘moral’ approach and promoted abstinence. However, most of the nurses in this study held the belief that sexual health
knowledge acts as an encouragement for sexual activity. Thus, as part of school health teams,
nurses need to embrace evidence that improved sexual health education may delay sexual initiation and prevent unintended pregnancy and HIV/STDs
Healthcare professionals’ experiences of delivering sexual and reproductive health services to adolescents: a literature review
Abstract This literature review was conducted systematically to identify the gap in knowledge and practice related to the provision of sexual health to adolescents worldwide. The search was limited to peer-reviewed articles published between 2002 and 2018. Thirty-two relevant articles were identified and reviewed for quality assessment by using the Hawker critical appraisal tool. The studies were conducted in Africa, Europe, Asia, Oceania, and the United States of
America (USA). The review findings suggested that potential tensions exist between the desire to prevent unwanted pregnancies and the provision of adolescent-friendly sexual health services in societies which disapprove of adolescents’ premarital sexual activity, contraception use and abortion services. Healthcare professionals should be aware of comprehensive sexual and reproductive health services as their professional responsibility and the need to manage
their own conflicts with regard to fulfilling their role
An overview of adolescents sexual and reproductive health services provision in Malaysia
Safer sex provision, including contraception information and services, should be made available to adolescents regardless of their marital status in strategies to reduce the incidence of unintended teenage pregnancies and the spread of STIs. In Malaysia, this information is still not being delivered formally to adolescents even though unintended teenage pregnancies and the practice of “baby dumping” are serious public health issues. The aims of this article are to describe the Malaysian context in terms of the need for comprehensive sexual and reproductive health information and treatment for unmarried adolescents. The article presents the key aspects of Malaysian society and the potential influence on the provision and delivery of sexual and reproductive health information and treatment to unmarried Malaysian adolescents that can be a reference for healthcare professionals especially school health nurses. The article also describes the establishment of sheltered homes, baby hatches and unregulated adoption processes as the initiatives being taken to address the issue of unintended teenage pregnancies. This article suggests that the policy and laws that require parental consent for accessing the services need to be reviewed and revised to ensure that specific services are available to adolescents in a safe environment that maintains confidentiality
Wilms’ tumour antigen 1 Immunity via DNA fusion gene vaccination in haematological malignancies by intramuscular injection followed by intramuscular electroporation: a Phase II non-randomised clinical trial (WIN)
Background: In the UK almost 7000 people are diagnosed with leukaemia each year, but despite continuing advances in diagnosis and treatment with new drugs, such as the tyrosine kinase inhibitors, the majority of these patients will eventually die from their disease. Until quite recently, the only treatment to offer the possibility of long-term disease-free survival was allogeneic stem cell transplantation. However, this carries a substantial risk of mortality and is available to only a minority of patients.Objectives: The aim of the study was to test the hypothesis that molecular and clinical responses, induced by T lymphocytes (T cells), can be predicted by increases in the number of CD8+ (cluster of differentiation 8-positive) T cells specific for the vaccine-encoded T-cell epitopes. This project also aimed to build on the established programme of deoxyribonucleic acid (DNA) fusion-gene vaccination delivered by intramuscular injection, exploiting a unique experience with electroporation, to induce durable immune responses with the aim of controlling disease by precision attack of the tumour by CD8+ T cells.Method: A non-randomised, open-label, single-dose-level Phase II clinical trial in two patient groups [chronic myeloid leukaemia (CML) and acute myeloid leukaemia (AML)] on stable doses of imatinib. Human leucocyte antigen A2-positive (HLA A2+) patients were vaccinated with two DNA vaccines: (1) p.DOM–WT1-37 (epitope sequence: VLDFAPPGA); and (2) p.DOM–WT1-126 (epitope sequence: RMFPNAPYL). The HLA A2-negative patients formed an unvaccinated control group. The sample size for the HLA A2+ group was originally determined following Simon’s optimal Phase II trial design (Simon R. Optimal two-stage designs for phase II clinical trials. Control Clin Trials 1989;10:1–10). This was changed to A’Hern’s single-stage design during the course of the trial (A’Hern RP. Sample size tables for single-stage phase II designs. Stat Med 2001;20:859–66), which was endorsed by the trial’s independent oversight committees.Results: The study included 12 patients with CML who were vaccinated and nine patients with CML who were unvaccinated as the control group. Both the vaccines and the electroporation were safe, with no new or unexpected toxicities. The evaluation adverse events of special interest (heart, bone marrow, renal) did not reveal safety concerns. Two BCR–ABL (breakpoint cluster region–Abelson murine leukaemia viral oncogene homolog 1) responses were observed, both of which were defined as a major response, with one in each group. Two Wilms’ tumour antigen 1 (WT1) molecular responses were observed in the vaccinated group and one was observed in the control group. At an immunological level, the vaccine performed as expected.Conclusions: The study met its primary decision-making target with one major molecular response in BCR–ABL transcript levels. Overall, the data showed, in this clinical setting, the immunogenicity and safety of the vaccine.Limitations: The study did not complete recruitment and there were multiple hurdles that contributed to this failure. This is disappointing given the robust induction immune responses against WT1 T-cell responses in 7 out of 10 evaluable patients.Future work: Evaluation of the p.DOM–WT1 vaccines in AML remains attractive clinically, but it is unlikely to be feasible at this time. Combination of the DNA vaccine approach with strategies to expand T-cell responses with immunomodulatory antibodies is in development.Funding details: This project was funded by the Efficacy and Mechanism Evaluation (EME) programme, a Medical Research Council (MRC) and National Institute for Health Research (NIHR) partnership, and Bloodwise
Establishment of the first sharia-compliant human milk bank: The IIUM experience in developing Halimatussaadia mother’s milk centre
Human milk has been recommended as the best and gold standard in infant feeding in terms of nutritional and immunological value including donor human milk. Donor human milk has gained demandin the recent years when mother own’s milk is not available. There has been an increasing number of human milk banks around the world especially in Southeast Asia. This is to aid in donor milk collection, processing and distribution of a safe donor human milk. In contrast to this
development, Muslim countries are still in debate in developing a sharia compliant human milk bank in view of concerns from Fiqh perspectives especially in milk kinship. We share our journey and challenges faced in developing and establishing “Halimatussaadia Mother’s Milk Centre” at Sultan Ahmad Shah Medical Centre @IIUM, the first Sharia-compliant human milk bank in Malaysia
Mutation screening using formalin-fixed paraffin-embedded tissues: a stratified approach according to DNA quality.
DNA samples from formalin-fixed paraffin-embedded tissues are highly degraded with variable quality, and this imposes a big challenge for targeted sequencing due to false positives, largely caused by PCR errors and cytosine deamination. To eliminate false positives, a common practice is to validate the detected variants by Sanger sequencing or perform targeted sequencing in duplicate. Technically, PCR errors could be removed by molecular barcoding of template DNA prior to amplification as in the HaloPlexHS design. Nonetheless, it is uncertain to what extent variants detected using this approach should be further validated. Here, we addressed this question by correlating variant reproducibility with DNA quality using HaloPlexHS target enrichment and Illumina HiSeq4000, together with an in-house validated variant calling algorithm. The overall sequencing coverage, as shown by analyses of 70 genes in 266 cases of large B-cell lymphoma, was excellent (98%) in DNA samples amenable for PCR of ≥400 bp, but suboptimal (92%) and poor (80%) in those amenable for PCR of 300 bp and 200 bp respectively. By mutation analysis in duplicate in 93 cases, we demonstrated that 20 alternative allele depth (AAD) was an optimal cut-off value for separating reproducible from non-reproducible variants in DNA samples amenable for PCR of ≥300 bp, with 97% sensitivity and 100% specificity. By cross validation with a previously established targeted sequencing protocol by Fluidigm-PCR and Illumina MiSeq, the HaloPlexHS protocol was shown to be highly sensitive and specific in mutation screening. To conclude, we proposed a stratified approach for mutation screening by HaloplexHS and Illumina HiSeq4000 according to DNA quality. DNA samples with good quality (≥400 bp) are amenable for mutation analysis with a single replicate, with only variants at 15-20 AAD requiring for further validation, while those with suboptimal quality (300 bp) are better analysed in duplicate with reproducible variants at >15 AAD regarded as true genetic changes
Inflammation, insulin resistance, and diabetes-mendelian randomization using CRP haplotypes points upstream
Background
Raised C-reactive protein (CRP) is a risk factor for type 2 diabetes. According to the Mendelian randomization method, the association is likely to be causal if genetic variants that affect CRP level are associated with markers of diabetes development and diabetes. Our objective was to examine the nature of the association between CRP phenotype and diabetes development using CRP haplotypes as instrumental variables.
Methods and Findings
We genotyped three tagging SNPs (CRP + 2302G > A; CRP + 1444T > C; CRP + 4899T > G) in the CRP gene and measured serum CRP in 5,274 men and women at mean ages 49 and 61 y (Whitehall II Study). Homeostasis model assessment-insulin resistance (HOMA-IR) and hemoglobin A1c (HbA1c) were measured at age 61 y. Diabetes was ascertained by glucose tolerance test and self-report. Common major haplotypes were strongly associated with serum CRP levels, but unrelated to obesity, blood pressure, and socioeconomic position, which may confound the association between CRP and diabetes risk. Serum CRP was associated with these potential confounding factors. After adjustment for age and sex, baseline serum CRP was associated with incident diabetes (hazard ratio = 1.39 [95% confidence interval 1.29-1.51], HOMA-IR, and HbA1c, but the associations were considerably attenuated on adjustment for potential confounding factors. In contrast, CRP haplotypes were not associated with HOMA-IR or HbA1c (p=0.52-0.92). The associations of CRP with HOMA-IR and HbA1c were all null when examined using instrumental variables analysis, with genetic variants as the instrument for serum CRP. Instrumental variables estimates differed from the directly observed associations (p=0.007-0.11). Pooled analysis of CRP haplotypes and diabetes in Whitehall II and Northwick Park Heart Study II produced null findings (p=0.25-0.88). Analyses based on the Wellcome Trust Case Control Consortium (1,923 diabetes cases, 2,932 controls) using three SNPs in tight linkage disequilibrium with our tagging SNPs also demonstrated null associations.
Conclusions
Observed associations between serum CRP and insulin resistance, glycemia, and diabetes are likely to be noncausal. Inflammation may play a causal role via upstream effectors rather than the downstream marker CRP
Outcome and biomarker analysis from a multi-centre phase 2 study of ipilimumab in combination with carboplatin and etoposide (ICE) as first line therapy for extensive stage small cell lung cancer.
BACKGROUND: To evaluate safety and efficacy of ipilimumab combined with standard first-line chemotherapy for patients with extensive stage SCLC. METHODS: Chemotherapy-naïve extensive stage SCLC patients were treated with carboplatin and etoposide up to six cycles. Ipilimumab 10 mg/kg was given on day 1 of cycles 3-6 and every 12 weeks. Response was assessed by RECIST v1.0 and immune related response criteria (irRC). The primary endpoint was 1-year progression-free survival (PFS) according to RECIST. Secondary endpoints included PFS by irRC (irPFS) and overall survival (OS). Autoantibody serum levels were evaluated and correlated with clinical outcomes. RESULTS: 42 patients were enrolled between September 2011-April 2014, 39 evaluable for safety and 38 for efficacy. 6/38 patients (15.8% [95% CI: 7.4%-30.4%]) were alive and progression-free at 1-year by RECIST. Median PFS was 6.9 months (95%CI: 5.5-7.9). Median irPFS was 7.3 months (95% CI: 5.5-8.8). Median OS was 17.0 months (95% CI: 7.9-24.3). In patients evaluable for response, 21/29 patients (72.4%) achieved an objective response by RECIST and 28/33 (84.8%) by irRC. All patients experienced at least one adverse event; 35/39 (89.7%) patients developed at least one toxicity ≥ Grade 3; in 27 (69.2%) this was related to ipilimumab. Five deaths were reported to be related to ipilimumab. The positivity of an autoimmune profile at baseline was associated with improved outcomes and severe neurological toxicity. CONCLUSION: Ipilimumab in combination with carboplatin and etoposide might benefit a subgroup of patients with advanced SCLC. Autoantibody analysis correlates with treatment benefit and toxicity and warrants further investigation
