Background
Dengue infection is the most prevalent mosquito-borne viral infection globally. Concurrently, there has also been an upsurge of non-communicable comorbidities. We aimed to investigate the association between these comorbidities and the development of severe dengue.
Methods
We performed a retrospective, case-control study involving 117 c...
Purpose
Bone tumours are increasingly treated with limb-salvage surgeries. However, implant infection is a devastating complication, greatly affecting the functional outcome. Yet, data on functional outcome post-implant infection are scarce. This study aims to determine the functional outcome and implant survival of these patients.

The development of nucleic-acid-based antimicrobials such as RNA-cleaving DNAzyme (RCD), a short catalytically active nucleic acid, is a promising alternative to the current antibiotics. The current rapid spread of antimicrobial resistance (AMR) in bacteria renders some antibiotics useless against bacterial infection, thus creating the need for alt...
Background: Due to an ageing population, dengue among older patients is encountered more frequently inmany
countries. Our study aimed to explore the clinico-laboratory parameters and outcomes among dengue-infected
older patients in comparison with younger patients.
Methods: This retrospective chart review involved dengue patients with dengue non-st...
This study explored the contribution of viral respiratory infections (VRIs) in dengue-like illness (DLI) patients and their distinguishing clinicolaboratory parameters. Two hundred DLI patients were prospectively recruited (1 July–1 October 2019) from a community clinic in Southern Malaysia. Patients ≥18 years with acute fever and fulfilling the WH...
There is a need for culturally competent health care providers (HCPs) to provide care to deaf signers, who are members of a linguistic and cultural minority group. Many deaf signers have lower health literacy levels due to deprivation of incidental learning opportunities and inaccessibility of health-related materials, increasing their risk for poo...
Background

Objective
While grappling with the Covid-19 outbreak, Malaysia continues to confront rising dengue cases. With no vaccines or antivirals available, integrative medicine (IM) increasingly offers popular alternatives to treat dengue infections. Thus, future healthcare professionals (HCPs) need to have adequate knowledge, attitude, and practice (KAP)...
Objective
Dengue infections remain at critical endemic levels in Malaysia but are at risk of being overshadowed with current focus and resources diverted towards battling the Covid-19 pandemic. Since effective antivirals and vaccines are lacking for dengue, along with the fear of contracting Covid-19 in healthcare facilities, local communities are...
We report the whole genome sequencing data and de novo genome assemblies for eight extended-spectrum beta-lactamases (ESBL) producing Enterobacteriaceae isolates from Malaysia consisting of four Klebsiella pneumoniae, two Enterobacter harmaechei, one Citrobacter freundii and one Escherichia coli. We identified at least one ESBL gene in each genome,...
Objectives:
Despite the increasing reports of carbapenem-resistant Enterobacteriaceae in Malaysia, genomic resources for carbapenem-resistant clinical strains of Klebsiella pneumoniae (K. pneumoniae) remain unavailable. This study aimed to sequence the genomes of multiple carbapenem-resistant K. pneumoniae strains from Malaysia and to identify the...
Background:
Dengue caused by dengue virus (DENV) serotypes -1 to -4 is the most important mosquito-borne viral disease in the tropical and sub-tropical countries worldwide. Yet many of the pathophysiological mechanisms of host responses during DENV infection remain largely unknown and incompletely understood.
Methods:
Using a mouse model, the mi...
Background
Dengue continues to be a major international public health concern. Despite that, there is no clinically approved antiviral for treatment of dengue virus (DENV) infections. In this study, geraniin extracted from the rind of Nephelium lappaceum was shown to inhibit the replication of DENV-2 in both in vitro and in vivo experiments.
Metho...
Background:
There is an escalation of frequency and magnitude of dengue epidemics in Malaysia, with a concomitant increase in patient hospitalization. Prolonged hospitalization (PH) due to dengue virus (DENV) infections causes considerable socioeconomic burden. Early identification of patients needing PH could optimize resource consumption and redu...
Background:
The frequency and magnitude of dengue epidemics continue to increase exponentially in Malaysia, with a shift in the age range predominance toward adults and an expansion to rural areas. Despite this, information pertaining to the extent of transmission of dengue virus (DENV) in the rural community is lacking. This community-based pilot...
Dengue virus (DENV) results in 100 million cases of infections and 22,000 deaths per year. Liver involvement, thrombocytopenia, haemorrhage and plasma leakage are characteristic manifestations of severe forms of DENV infection. However, the molecular pathways of DENV infection have not been comprehensively studied compared to the host immunological...
Both obesity and DENV infections are growing public health concerns that have far-ranging socioeconomic effects, especially in developing countries. Despite the increasing prevalence of these conditions, there is a scarcity of data investigating the potential relationships between these two entities. Our study aims to examine the influence of obesi...
We report the whole-genome sequences of two carbapenem-resistant clinical isolates of Klebsiella quasipneumoniae subsp. similipneumoniae obtained from two different patients. Both strains contained three different extended-spectrum β-lactamase genes and showed strikingly high pairwise average nucleotide identity of 99.99% despite being isolated 3 y...
Severe thrombocytopenia is common in dengue virus (DENV) infections. However, studies focusing on the role of profound thrombocytopenia (PT) (nadir platelet counts ≤ 20 000/mm3) in DENV infections are scarce. This study aims to identify the associated features and outcome of DENV patients with PT. It involves 237 adult hospitalized patients who wer...
Background
Globally, dengue infections constitute a significant public health burden. In recent decades, Malaysia has become a dengue hyper-endemic country with the co-circulation of the four dengue virus serotypes. The cyclical dominance of sub-types contributes to a pattern of major outbreaks. The consequences can be observed in the rising incide...
Background
The co-circulation of 4 DENV serotypes in geographically expanding area, has resulted in increasing occurrence of DENV co-infections. However, studies assessing the clinical impact of DENV co-infections have been scarce and have involved small number of patients. This study explores the impact of DENV co-infection on clinical manifestati...
Numerous studies have described various complications after endoprosthetic reconstructive operations. However, there are limited reports that focus specifically on deep infections (e.g., deep incisional surgical site infections), which remain one of the most dreaded complications of these operations, with rates ranging from 10% to 17%. Thus, this s...
