Malaria is a life-threatening, preventable, and curable vector borne disease caused by parasites that are transmitted to people through the bites of infected female Anopheles. The WHO Global Report 2010-2016 reported insecticide resistance in malaria. The main objective of this study is to determine the effectiveness of new generation Long-Lasting Insecticidal Nets (LLIN) compared to standard LLIN and untreated nets in terms of the mortality rate of adult female Anopheles gambiae. A comprehensive review of the literature was published in three databases (PubMed, Ovid, EBSCO Host) since 2010. Publications were searched with keywords including malaria, long-lasting treated bed net, long lasting insecticide-treated bed net, LLIN, and experimental hut. The search has identified 60 articles. Based on the PRISMA flowchart, 10 articles are qualified for data collection and analysis. The gathered data was analysed using Review Manager. Following meta-analysis between subgroups, a risk difference of 0.31 between standard LLINs versus untreated net (p<0.001, I²=100% 95% CI:0.01,0.60). A comparison of upgraded LLINs with the untreated net has shown a significant difference with a pooled risk difference of 0.54 favours upgraded LLINs (p<0.001, I²=100% 95% CI: 0.54,0.84). Comparison between upgraded LLINs versus standard gave an overall risk difference of 0.24 (p < 0.001, I² = 100%, 95% CI: 0.10–0.39). Upgraded LLINs significantly increase Anophelesmortality compared to standard LLINs and untreated nets, suggesting their potential for improved malaria control. Thus, using upgraded nets in the field and translating them into malaria preventive programs would help achieve the target and improve healthoutcomes for those living in endemic areas.

Dengue remains a public health threat that consumes a significant number of resources for its prevention and control. This systematic review aimed to solidify recent costing evidence in dengue management among South East Asian (SEA) countries. All studies conducted between 2010 and 2020 were retrieved using four international databases i.e. PubMed, Scopus, Web of Science, and Emerald Insight. The review was reported according to PRISMA guidelines. Quality assessments were done independently by two reviewers using a checklist adapted for the cost of illness studies. We identified 13 original articles representing several SEA countries. Among the common reported costing measure include total cost/ health expenditure; direct medical cost; direct non-medical cost; and indirect cost. The estimated total cost for dengue management varied between countries largely due to the difference in the total incidence of dengue cases. The estimated cost spent on dengue per capita GDP ranges from less than 0.001% to 0.1%, depending on the recorded number of dengue cases of the year. The majority of the articles focused on the economic burden from the perspective of treatment such as hospitalization and ambulatory care. In a nutshell, the economic burden of managing dengue infection is costly and the evidence suggests a steady increase in health expenditure with the growing number of dengue cases

Environmental Determinants in Sustaining the Transmission of Lymphatic Filariasis: A Systematic Review IntroductionSince mass drug administration continues in many of the endemic countries, it is vital to synthesise evidence to adapt the challenges contributed by the environments. As such, the aim of this review was to explore relationship between lymphatic filariasis prevalence and potential environmental determinants .MethodsWe searched the electronic databases PubMed, Web of Science, Cochrane, and Scopus between Jan 1, 2013, and Dec 31, 2022, for studies fulfilling the following criteria: it was an original article investigating the environmental determinants associated with transmission of lymphatic filariasis; and the study was published in English. The quality assessment tools for observational studies from the National Heart, Lung, and Blood Institute was used to assess the study quality. This systematic review was registered with the PROSPERO database (CRD42023393018).ResultsWe identified 409 potentially eligible published articles, of which 11 met our inclusion criteria. The main environmental determinants associated with lymphatic filariasis transmission were Normalised Difference Vegetation Index (NDVI), land cover, distance to waterbody, rainfall/precipitation, elevation, slope, day land surface temperature, average annual temperature, house type and distance to stable light. ConclusionsThis review is one of the steps towards understanding the associations between environmental determinantsand transmission of lymphatic filariasis. These results can be used in future evidence-based strategies to strengthen surveillance and control strategies.

Socio-Ecological Framework on Risk of Prolonged Dengue Outbreak in Seremban District: A Qualitative Study IntroductionA prolonged duration of a dengue outbreak in a locality poses a detrimental risk to the susceptible population. There have been limited studies looking into the socio-ecological factors that can be modified to break the chain of transmission. Therefore, this study aimed to explore and identify the socio-ecological attributes experienced by the health authority in the Seremban district.MethodsA qualitative study was performed using an in-depth interview (IDI) technique based on semi-structured questionnaires. Results were thematically analysed when theoretical saturation was achieved.ResultsA total of 12 respondents participated in this study, representing various backgrounds and involved in dengue control activities. There were nine modifiable socio-ecological themes generated, namely (1) illegal dumpsite, (2) illegal gardens, (3) illegal man-made structures, (4) old unused items, (5) idle damaged vehicles, (6) construction site, (7) drainage system, (8) physical structure, and (9) lack of community engagement. A model framework was conceptualised from the analysis. The health authority identified that these issues require urgent attention and collaborative action by various stakeholders.ConclusionThe identified socio-ecological factors have been a challenge for the health authority. Nevertheless, identifying these attributes signifies the key to tackling the prolonged duration of the dengue outbreak. Ultimately, a multi-agency approach and community participation are vital to ensure a sustainable vector control program.

Introduction: Acne is the most common skin disease among adolescents and has significant psychological distress. Our objective is to assess acne severity, functional disability, and its psychological distress among acne patients. Methods: A cross-sectional study was conducted from November 2021 to May 2022 among 163 acne patients attending Dermatology Clinics in the district of Kuantan, Pahang. The severity of acne was graded using the Comprehensive Acne Severity Scale (CASS). The functional disability index was measured using a Cardiff Acne Disability Index (CADI), while Depression, Anxiety and Stress Scale (DASS-21) questionnaires were used as a screening tool to detect the psychological distress of acne. Data were analysed using a Chi-square test, Fisher’s exact test and multiple logistic regression. Results: The mean age was 23 years, 60.1% were female, 94.5% were Malay, and 68.1% were unemployed. The severity of acne was more prominent in the mild (30.7%) and moderate (28.2%) categories. A total of 20.2%, 11.7%, and 4.9% of the respondents had anxiety, depression, and stress symptoms, respectively. Regarding the respondents’ functional disability, 40.5% had mild impairment, 38.0% had moderate impairment, and 13.5% had severe impairment. Acne severity was found to be significantly associated with the functional disability index (P<0.05). The functional disability index was also found to be significantly associated with depression (p=0.019) and anxiety symptoms (p=0.042). Conclusion: Clinical management of acne patients should include not only pharmacological treatment but also consideration of the disease’s functional disability status and psychological distress.

Atrial fibrillation (AF) is a prevalent cardiac arrhythmia affecting millions of individuals worldwide and posing significant challenges to healthcare systems. The growing body of research has uncovered sex-related differences in AF pathophysiology, including the role of fatty acid-binding protein 4 (FABP4) and leptin as potential biomarkers. FABP4 and leptin, key adipokines involved in cardiovascular health, have been linked to inflammation, oxidative stress, and endothelial dysfunction, all of which may contribute to AF development. These adipokines exhibit sex-specific differences in their concentrations, with females generally showing higher FABP4 levels and males displaying distinct leptin profiles. Furthermore, hormonal influences, particularly estrogen, and testosterone, play significant roles in shaping AF risk and atrial remodeling. Estrogen is associated with cardioprotective effects, while testosterone may exert proarrhythmic effects. Understanding these sex-specific mechanisms could lead to more tailored and effective clinical management of AF. The future of AF research holds promise for precision medicine, novel therapeutic targets, artificial intelligence integration, and personalized care approaches. Emphasizing patient-centered care, telemedicine, and multidisciplinary collaboration can further enhance AF management and improve patient outcomes. In conclusion, recognizing and addressing sex-related factors in AF pathophysiology offer opportunities for gender-responsive interventions and advancements in AF management. Implementing these insights may pave the way for targeted therapies and improved quality of life for individuals affected by AF.

Background: and Purpose Repetitive transcranial magnetic stimulation (rTMS) of the cerebellar hemisphere represents a new option in treating essential tremor (ET) patients. We aimed to determine the efficacy of cerebellar rTMS in treating ET using different protocols regarding the number of sessions, exposure duration, and follow-up duration. Methods: A randomized sham-controlled trial was conducted, in which 45 recruit patients were randomly allocated to 2 groups. The first (active group) comprised 23 patients who were exposed to 12 sessions of active rTMS with 900 pulses of 1-Hz rTMS at 90% of the resting motor threshold daily on each side of the cerebellar hemispheres over 4 weeks. The second group (sham group) comprised 22 patients who were exposed to 12 sessions of sham rTMS. Both groups were reassessed at baseline and after 1 day, 1 month, 2 months, and 3 months using the Fahn-Tolosa-Marin tremor-rating scale (FTM). Results: Demographic characteristics did no differ between the two groups. There were significant reductions both in FTM subscores A and B and in the FTM total score in the active-rTMS group during the period of assessment and after 3 months (p=0.031 and 0.011, respectively).However, subscore C did not change significantly from baseline when assessed at 2 and 3 months (p=0.073 and 0.236, respectively). Furthermore, the global assessment score was significantly higher in the active-rTMS group (p>0.001). Conclusions Low-frequency rTMS over the cerebellar cortex for 1 month showed relative safety and long-lasting efficacy in patients with ET. Further large-sample clinical trials are needed that include different sites of stimulation and longer follow-ups.

A plethora of paraneoplastic syndromes have been reported as remote effects of colorectal carcinoma (CRC). However, there is a dearth of data pertaining to the association of this cancer with demyelinating neuropathies. Herein, we describe the case of a young woman diagnosed with chronic inflammatory demyelinating polyneuropathy (CIDP). Treatment with intravenous immunoglobulins and prednisone did not improve her condition, and her neurological symptoms worsened. Subsequently, she was readmitted with exertional dyspnea, lightheadedness, malaise, and black stools. Colonoscopy revealed a necrotic mass in the ascending colon, which directly invaded the second part of the duodenum. Pathologic results confirmed the diagnosis of locally advanced CRC. Upon surgical resection of the cancer, her CIDP showed dramatic resolution without any additional therapy. Patients with CRC may develop CIDP as a type of paraneoplastic syndrome. Clinicians should remain cognizant of this potential association, as it is of paramount importance for the necessary holistic clinical management.
