Prevalence and factors associated with erectile dysfunction in male patients with human immunodeficiency virus in a teaching hospital in west Malaysia

Introduction: Erectile dysfunction (ED) has been associated with the treatment of human immunodeficiency virus (HIV) and chronic diseases. Sexual dysfunction data of male patients infected with HIV are still scarce in Malaysia, and ED appears to be under-reported. Therefore, this study aims to determine the prevalence and predictors of ED among male HIV patients at the University Malaya Medical Centre. Methods: A cross sectional study was conducted among male HIV patients on antiretroviral therapy (ART) attending the outpatient clinic of a teaching hospital in Malaysia. A systematic random sampling method was employed in the selection of respondents. Participants were interviewed using a structured questionnaire with a 15-item international index of erectile function (IIEF-15). An appropriate statistical analysis was used to determine the associate and potential risk factors. Results: A total of 220 males participated in this study with a mean age of 37.9±9.9; prevalence of ED among HIV patients was 82.3 % (n=180). The severity of ED was further categorized into: severe (24.1%), moderate (19.1%), mild to moderate (20.9%), and mild (18.3%). In a multivariate logistic regression analysis, patients with a lower educational background were more likely to be associated with ED (odds ratio [OR] 2.62, 95% confidence interval [CI] 1.02-6.72; p-value 0.046). Conclusion: This study reports that ED was prevalent among adult HIV males who are on an ART regimen. Those with a lower educational background are more likely to have ED. Hence, in managing patients with HIV, physicians should seek to identify those patients at risk of developing ED for further intervention

Using clinical practice guidelines to manage dengue: a qualitative study in a Malaysian hospital.

BACKGROUND: Malaysia has rising dengue incidence. World Health Organization clinical practice guidelines for managing dengue have been adapted by the Ministry of Health in Malaysia, with evidence of good awareness by clinicians. However, dengue mortality has not reduced. This study aimed to explore the challenges of dengue management for Medical Officers, with a particular focus on use of clinical practice guidelines. METHODS: Qualitative study using six focus groups and 14 semi-structured interviews with doctors responsible for dengue management at a large tertiary hospital in Malaysia. RESULTS: Dengue was recognised as difficult to diagnose and manage. Wide awareness and use of both WHO and Ministry of Health guidelines was reported, but several limitations noted in their coverage of particular patient groups. However, the phrase 'guidelines' also referred to local algorithms for fluid management, which were less clinically evidence-based. Where Medical Officers were well trained in the appropriate use of evidence-based guidelines, barriers to use included: the potential for 'following the algorithm' to undermine junior clinicians' claims to clinical expertise; inability to recognise the pattern of clinical progress; and lack of clinical experience. Other reported barriers to improved case management were resource constraints, poor referral practices, and insufficient awareness of the need for timely help seeking. CONCLUSIONS: Awareness of clinical practice guidelines is a necessary, but not sufficient, condition for optimal dengue management. In high prevalence settings, all clinical staff would benefit from regular dengue management training which should include diagnosis, practice in monitoring disease progression and the use of clinical practice guidelines in a range of clinical contexts

Adverse events following immunization and psychological distress among cancer patients/survivors following vaccination against SARS-CoV-2 infection

PurposeThis study aims to describe the adverse events following immunization (AEFIs) of SARS-CoV-2 vaccination in cancer patients/survivors associated with their psychological distress.MethodsA cross-sectional study was conducted to assess AEFIs after the receipt of SARS-CoV-2 vaccines in cancer patients/survivors attending a university hospital in Malaysia. Psychological distress was measured using the Hospital Anxiety and Depression Scale (HADS) before and after the first and second doses of COVID-19 vaccine.ResultsA total of 217 complete responses were received. Compared with before vaccination, both HADS Anxiety (HADS-A) and HADS Depression (HADS-D) scores were significantly reduced after the first and second dose of the SARS-CoV-2 vaccine. Most of the participants had mild-or-moderate systemic and local AEFIs, with the most common being pain at the injection site, tiredness, and headache for both the first and second doses of the vaccine. Positive correlations between the total AEFI score and HADS-A (r = 0.309, p < 0.001) and HADS-D (r = 0.214, p = 0.001) scores were observed after the first dose of the SARS-CoV-2 vaccine. Similarly, positive associations were observed between the total AEFI score and HADS-A (r = 0.305, p < 0.001) and HADS-D (r = 0.235, p < 0.001) scores after the second dose of the SARS-CoV-2 vaccine.ConclusionMild-to-moderate AEFIs found in this study help address vaccine hesitancy in cancer patients/survivors. Receiving the SARS-CoV-2 vaccine had a positive effect on decreasing psychological distress in cancer patients/survivors. High severity of an AEFI was associated with higher anxiety and depressive symptoms

Changing predominant SARS-CoV-2 lineages drives successive COVID-19 waves in Malaysia, February 2020 to March 2021

Malaysia has experienced three waves of coronavirus disease 2019 (COVID-19) as of March 31, 2021. We studied the associated molecular epidemiology and SARS-CoV-2 seroprevalence during the third wave. We obtained 60 whole-genome SARS-CoV-2 sequences between October 2020 and January 2021 in Kuala Lumpur/Selangor and analyzed 989 available Malaysian sequences. We tested 653 residual serum samples collected between December 2020 to April 2021 for anti-SARS-CoV-2 total antibodies, as a proxy for population immunity. The first wave (January 2020) comprised sporadic imported cases from China of early Pango lineages A and B. The second wave (March–June 2020) was associated with lineage B.6. The ongoing third wave (from September 2020) was propagated by a state election in Sabah. It is due to lineage B.1.524 viruses containing spike mutations D614G and A701V. Lineages B.1.459, B.1.470, and B.1.466.2 were likely imported from the region and confined to Sarawak state. Direct age-standardized seroprevalence in Kuala Lumpur/Selangor was 3.0%. The second and third waves were driven by super-spreading events and different circulating lineages. Malaysia is highly susceptible to further waves, especially as alpha (B.1.1.7) and beta (B.1.351) variants of concern were first detected in December 2020/January 2021. Increased genomic surveillance is critical

Evaluation of the role of sales promotion in influencing impluse buying behaviour: a comparison between international and local tourist at premium outlet in Malaysia

The growing number of premium outlets in Malaysia has led to a new shopping experience to both local and international tourists. Associated with the concept of ‘everyday discount’, premium outlets would attract more consumers to purchase at the outlets. Previous studies have revealed the significant influence of sales promotion on consumer purchase behaviour as well as impulse buying behaviour. However, there are limited studies identifying the role of sales promotion on impulse buying behaviour in the perspective of international and local tourists. Moreover, previous research of literature on the premium outlets, especially in Malaysia are still lacking. Therefore this study aims to evaluate the role of sales promotion on impulse buying in the perspective of international and local tourists at premium outlets in Malaysia. Data were collected from 359 tourists at five premium outlets in Malaysia, using a self-administered questionnaire. The result of the study indicates that both groups have different preferences in terms of sales promotion that induced them to make an impulse purchase. This study suggests that retailers or marketers should improvise their pricing strategies and give out more samples and gifts to attract tourists to spend more money

Effect of Blastocystis sp. in dengue patients—Increase in the treatment cost and exacerbation of symptoms

Increasing incidences of dengue have become a global health threat with major clinical manifestation including high fever and gastrointestinal symptoms. These symptoms were also expressed among Blastocystis sp. infected individuals, a parasite commonly seen in human stools. This parasite has been previously reported to replicate faster upon exposure to high temperature. The present study is a hospitalized-based cross-sectional study involved the collection of faecal sample from dengue patients. Stool examination was done by in vitro cultivation to isolate Blastocystis sp. Growth pattern of all the positive isolates were analyzed to identify the multiplication rate of Blastocystis sp. isolated from dengue patients. Distribution of Blastocystis sp. among dengue patients was 23.6%. Dengue patients who were positive for Blastocystis sp. infection denoted a significantly higher fever rate reaching 38.73C (p<0.05) compared to the non-Blastocystis sp. infected patients (38.44C). It was also found that Blastocystis sp. infected patients complained of frequenting the toilet more than five times a day (p<0.05) compared to those who were non-Blastocystis sp. infected. At the same time, the duration of hospitalization was significantly longer (p<0.05) for Blastocystis sp. infected dengue patients compared to the non-Blastocystis sp. infected patients. Besides, Blastocystis sp. isolated from dengue patients (in vivo thermal stress) showed a higher growth rate compared to the non-dengue isolated which was exposed to high temperature (in vitro thermal stress). Our findings suggest that presence of Blastocystis sp. during dengue infection could trigger the increase of temperature which could be due to highly elevated pro inflammatory cytokines by both parasitic and virus infection. This could justify why the temperature in Blastocystis sp. infected dengue patients is higher compared to the non-Blastocystis sp. infected patients. Higher temperature could have triggered a greater parasite multiplication rate that contributed to the aggravation of the gastrointestinal symptoms. © 2019 Thergarajan et al.

Review of Dengue Hemorrhagic Fever Fatal Cases Seen Among Adults: A Retrospective Study

<div><p>Background</p><p>Dengue is a mosquito-borne viral disease endemic in many countries in the tropics and sub-tropics. The disease affects mainly children, but in recent years it is becoming more of an adult disease. Malaysia experienced a large dengue outbreak in 2006 to 2007, involving mostly adults, with a high number of deaths.</p><p>Methodology/Principal Findings</p><p>We undertook a retrospective study to examine dengue death cases in our hospital from June 2006 to October 2007 with a view to determine if there have been changes in the presentation of severe to fatal dengue. Nine of ten fatal cases involved adult females with a median age of 32 years. All had secondary dengue infection. The mean duration of illness prior to hospitalization was 4.7 days and deaths occurred at an average of 2.4 days post-admission. Gastrointestinal pain, vomiting, diarrhea, intravascular leakages and bleeding occurred in the majority of cases. DSS complicated with severe bleeding, multi-organ failure and coagulopathy were the primary causes of deaths. Seven patients presented with thrombocytopenia and hypoalbuminemia, five of which had hemoconcentration and increased ALT and AST indicative of liver damage. Co-morbidities particularly diabetes mellitus was common in our cohort. Prominent unusual presentations included acute renal failure, acute respiratory distress syndrome, myocarditis with pericarditis, and hemorrhages over the brain and heart.</p><p>Conclusions</p><p>In our cohort, dengue fatalities are seen primarily in adult females with secondary dengue infection. The majority of the patients presented with common clinical and laboratory warning signs of severe dengue. Underlying co-morbidities may contribute to the rapid clinical deterioration in severe dengue. The uncommon presentations of dengue are likely a reflection of the changing demographics where adults are now more likely to contract dengue in dengue endemic regions.</p></div

Case report : Actinomyces naeslundii complicating preterm labour in a trisomy-21 pregnancy

Preterm birth is a global concern with considerable morbidity and mortality. Intrapartum infection is a known cause of preterm birth and Actinomyces infection is one of the infections contributing to preterm birth. We report a case of preterm birth of a trisomy-21 neonate to a mother with positive Actinomyces naeslundii from an intra-operative placental swab sample and discussed the relationship of this bacteria and preterm delivery, and the role of postpartum antibiotics use in this case
