Introduction: Staphylococcus aureus is the leading biofilmforming microorganisms in orthopaedic implant infections. The biofilms formed are difficult to eradicate and resistance to antibiotics. This current study aims to determine the effectiveness of povidone-iodine; an antiseptic solution in eradicating S. aureus biofilm on stainless steel alloy. In addition to the usual Colony-Forming Unit (CFU) used for verification, Scanning Electron Microscope (SEM) is used to validate the formation and eradication of the biofilms. Materials and methods: This is an in vitro study where the biofilm is formed by inoculating clinically isolated S. aureus, incubated for 24 hours onto stainless steel alloy 316L implants. The implants are then irrigated using povidoneiodine solution with varying concentrations (5 and 10%) and durations (30, 60, and 180 seconds). The anti-biofilm effect was evaluated using plating and SEM methods to confirm its effectiveness. The process is repeated after 24 hours of postirrigation reincubation to detect any rebound growth. Results: No biofilm seen after irrigation with povidoneiodine at 5% and 10% concentrations at 30, 60 and 180 seconds, respectively, in both CFU count and SEM. This result is replicated after 24 hours of reincubation, in assessing for rebound growth. Conclusion: Our study supports that a minimum of 5% povidone-iodine with a minimum irrigation time of 30 seconds are effective at eliminating S. aureus biofilm on stainless steel alloy implants. Both CFU count and SEM yield similar value in validating the presence of biofilm. Additionally, SEM allows visualisation of the morphology of the biofilm.

Introduction: Patellar fractures were common and often challenging to manage, particularly in the elderly population. Achieving stable anatomic reduction and maintaining it throughout the perioperative period was crucial for restoring knee function, especially in patients with osteopenic bone. Materials and methods: This was a retrospective case series of geriatric patients who presented to our centre with closed transverse patellar fractures between 2022 and 2023. All fractures were classified as AO 34C1 under the Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification and were considered fragility fractures, having resulted from a fall from standing height. Only patients aged over 60 years were included. All underwent open reduction and internal fixation using cannulated screws with suture tape augmentation. The Knee Society Score (KSS) was evaluated at four months post-operatively, and patients were followed for complications for up to one year. Results: Six cases met the inclusion criteria. The mean displacement was 19mm, and the average operative time was 45.17 minutes. The average time to radiographic union was 8.67 weeks. At a mean follow-up of 12.8 months, none of the patients required revision surgery or hardware removal. No patient reported issues related to implant prominence or pain during kneeling. The KSS at four months ranged from 87 to 97, with a mean score of 91. Conclusion: Cannulated screw fixation with suture tape augmentation appeared to be a safe and effective method for treating transverse patellar fractures in the elderly population, offering stable fixation and favourable functional outcomes.

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.

During the coronavirus disease 2019 (COVID-19) pandemic, the worldwide medical education system was affected tremendously due to the suspension of clinical activities and lockdown to prevent the spread of the disease. The delivery of clinical training was modified to alternative methods including online classrooms, recorded video, use of simulated patients and hybrid teaching. Several institutions worldwide chose to postpone their scheduled examination, which requires physical attendance or opted for virtual examination. Malaysian centralised postgraduate orthopaedic exit examination was postponed in 2020 and later recommenced in 2021 with three different centres across the country: north, east and central Malaysia. This article describes the preparation and challenges faced in conducting a face-to-face clinical exit examination for postgraduate orthopaedic candidates in Universiti Putra Malaysia in May 2021, during the Conditional Movement Control Order phase. The examination was a success, and no outbreak of COVID-19 was reported from the event.

The increasing number of drug-resistant pathogens is a global issue and becoming worse because it has reduced the effectiveness of current antibiotics in the management of infectious diseases. Therefore, this situation highlights the urgency of an action plan to identify and develop novel and potent antimicrobials derived from natural resources. Therapeutic compounds from natural resources can offer novel, straightforward approaches against pathogenic bacteria with the least toxic manifestations and a low risk of acquiring resistance. Marine organisms and coastal plants receive much interest among researchers nowadays for developing new pharmaceuticals because they are rich in secondary metabolites that have various pharmacological effects, such as antibacterial, anti-cancer, antiviral, anti-inflammatory and others. This review's goal is to highlight the phytochemical components of marine organisms and coastal plants that might be accountable for their antibacterial properties that have been scientifically confirmed and can be potential aids in treating infectious diseases caused by multidrug resistant (MDR) bacteria in humans.

Breast and hepatic cancers are the leading incidences in the globe occurring of the human sufferings from various cancers. Snake venoms have been reported to provide effective therapeutic agents. The current study investigates the anticancer potency of Egyptian venoms snakes on two cells: breast cancer cells (MCF-7) and hepato-cancer cells (HepG2) (In vitro assay). The examined venoms were more potent on MCF-7 than HepG2 cells. Their inhibition % on MCF-7 ranged from 71.47 to 99.02% with medium inhibition concentrations (IC50s): 3.48, 3.60, 3.70, 4.33, and 4.49 μg/ml for venoms: Echis pyramid (E.H), Cerastes vipera (C.V), Naja haje (N.H), Echis coloratus (E.C), and Cerastes cerastes (C.C), respectively. The values of IC50s on HepG2 were 4.32, 17.77, 59.72, 63.75, and 217.90 μg/ml for toxins: E.C, E.P, C.V, C.C, and N.H, respectively. Some biomarkers were conducted to investigate the apoptotic effects of toxins into the cells. Increasing profiles of lactate dehydrogenase (LDH) activity and levels of glutathione content (GSH) and malodialdhyde (MDA) as well as repairment of DNA indicated such these actions. So, more reliable investigations on these venoms were needed to provide intelligent therapeutic agent for cancer treatment.

Purpose: This study aimed to describe the prevalence of vitamin D deficiency in Indonesian children and adolescents. Methods: This was a meta-analysis of prevalence using the Hartung-Knapp-Sidik-Jonkman method with a random effects model. A prediction interval was used to estimate true effects. We searched PubMed, MEDLINE, Cochrane Library, Science Direct, Google Scholar, and 3 Indonesian databases (Indonesian Scientific Journal Database, Neliti, and Indonesia One Search). We included cross-sectional or case-control studies that provided data on the prevalence of vitamin D deficiency. We excluded case reports, case series, cohort studies, or studies outside Indonesia. We computed point prevalence by dividing the number of children with hypovitaminosis D by the total number of subjects in that study. This review was registered with PROSPERO (International Prospective Register of Systematic Reviews) (CRD42022329814). Results: Of 1,397 manuscripts identified, 7 were included in this review. A total of 5,870 children were included in this meta-analysis, ranging in age from 6 months to 19 years. The prevalence of hypovitaminosis D in Indonesia was calculated as 33% (95% confidence interval [CI], 9–56) and was higher in females (60% [95% CI, 58–62]) than in males (40% [95% CI, 38–42]). Mean serum vitamin D level was 22.74 ng/mL (95% CI, 16.95–30.51) with a prediction interval of 15.96 ng/mL to 29.52 ng/mL. Conclusion Vitamin D deficiency is a public health emergency in Indonesia. Strategies to detect and treat vitamin D deficiency in Indonesian children and adolescents should be implemented immediately.

Rare but serious thrombotic incidents in relation to thrombocytopenia, termed vaccine-induced immune thrombotic thrombocytopenia (VITT), have been observed since the vaccine rollout, particularly among replication-defective adenoviral vector-based severe acute respiratory syndrome coronavirus 2 vaccine recipients. Herein, we comprehensively reviewed and summarized reported studies of VITT following the coronavirus disease 2019 (COVID-19) vaccination to determine its prevalence, clinical characteristics, as well as its management. A literature search up to October 1, 2021 using PubMed and SCOPUS identified a combined total of 720 articles. Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline, after screening the titles and abstracts based on the eligibility criteria, the remaining 47 full-text articles were assessed for eligibility and 29 studies were included. Findings revealed that VITT cases are strongly related to viral vector-based vaccines, which are the AstraZeneca COVID-19 vaccine (95%) and the Janssen COVID-19 vaccine (4%), with much rarer reports involving messenger RNA-based vaccines such as the Moderna COVID-19 vaccine (0.2%) and the Pfizer COVID-19 vaccine (0.2%). The most severe manifestation of VITT is cerebral venous sinus thrombosis with 317 cases (70.4%) and the earliest primary symptom in the majority of cases is headache. Intravenous immunoglobulin and non-heparin anticoagulant are the main therapeutic options for managing immune responses and thrombosis, respectively. As there is emerging knowledge on and refinement of the published guidelines regarding VITT, this review may assist the medical communities in early VITT recognition, understanding the clinical presentations, diagnostic criteria as well as its management, offering a window of opportunity to VITT patients. Further larger sample size trials could further elucidate the link and safety profile.
