Purpose: Adjuvant radiotherapy (RT), while effective in reducing cancer recurrence and improving survival
rates, often comes with radiation toxicity that can adversely affect the patient’s quality of life (QoL). Evaluating
toxicity after RT is crucial because it helps to identify and manage adverse effects that can significantly impact
a patient’s QoL. By monitoring toxicity, we can adjust treatment plans to mitigate these effects, improve patient
comfort, and ensure a better overall outcome. Therefore this study aimed to evaluate and compare QoL following
3D-conformal hypofractionated RT in breast cancer patients. Methods: We included twenty-one Malaysian women
with unilateral breast cancer treated with lumpectomy (n=15) or mastectomy (n=6) followed by 3D-conformal
hypofractionated RT. QoL was evaluated using the EORTC QLQ-BR45 questionnaire before, during, and
after RT. Results: During RT, there was a significant increase in the mean score of the breast symptoms scale
compared to baseline (p=0.002), with the most common symptoms being skin problems, followed by swelling and
oversensitivity. However, these symptoms were generally mild for most patients. The other quality of life scales
remained stable during RT. Post-RT, most QoL scales showed improvements compared to both baseline and
during RT, with significant enhancements in the mean breast symptoms score and breast satisfaction score (all
p<0.05). Conclusion: Radiotherapy negatively impacted the QoL of our breast cancer patients, specifically on the
breast symptoms scale. However, these symptoms improved after 4 months, resulting in high breast satisfaction
and indicating a near-excellent cosmetic outcome. Future studies with larger cohorts are essential to validate
these findings, as the small sample size (n=21 at baseline; n=13 post-RT) may have limited the detection of more
subtle changes

INTRODUCTION: In the clinical setting, erectile dysfunction (ED) is a significant issue
that should not be neglected, as it can adversely impact the quality of life of patients
and their partners, especially among overweight and obese populations. This study
aims to determine the prevalence of ED and its associated factors among non-diabetic,
overweight, and obese patients who attend a government health clinic in Kuantan,
Pahang, Malaysia. MATERIALS AND METHODS: A six-month cross-sectional study
was conducted from February 2024 to August 2024 at twelve health clinics in
Kuantan, Pahang. The selected respondents were married men over 18 years old, and
those with diabetes mellitus, cardiovascular disease, psychiatric illness, or illiteracy were
excluded. Data were collected using the validated Malay version of the International
Index of Erectile Function (IIEF-5). ED was defined as an IIEF-5 score of less than
22. Descriptive analysis and simple and multiple logistic regression were performed
using SPSS. RESULTS: All 221 eligible patients in the study responded (100% response
rate). The prevalence of ED was 66.1% (n=146). Multiple logistic regression
showed that ED was significantly associated with dyslipidemia [AOR (95% CI): 2.42
(1.06–5.52); p-value=0.036], anxiety [AOR (95% CI): 3.99 (1.44–11.01);
p-value=0.008] and older age [AOR (95% CI): 1.07 (1.02–1.12); p-value=0.009].
CONCLUSION: The study revealed a high prevalence of ED among non-diabetic
overweight and obese patients, potentially linked to increasing age, dyslipidemia, and
anxiety. Increasing awareness among the public and healthcare providers could
improve detection rates in primary care.

Journal of Veterinary Science 2026;27(1):e4-
Objective:
This study aims to describe histological manifestations and characterise the CDV strain in the tiger to determine its molecular epidemiology and postulate viral pathogenicity.
Methods:
Histopathology characterisation of the infected tissues were performed through haematoxylin and eosin and immunohistochemistry staining, respectively. We conducted virus isolation and titration in Chinese hamster ovarian expressing the dog signalling lymphocytic activation molecule (CHO-SLAM) cells. Reverse transcription polymerase chain reaction was performed to confirm the presence of CDV RNA, nucleotide and amino acid sequence analyses for comprehensive characterisation of the CDV strain.
Results:
Notable histopathological changes were observed primarily in the brain, lung, liver, kidney, spleen, and stomach, with viral antigens localised in the lung, liver, kidney, and stomach tissues. CDV-induced cell cytopathic effects yielding 4.27 × 10 6 TCID 50 /mL were observed at 48 h post-inoculation in CHO-SLAM cells. Phylogenetic analysis suggested that the virus originated from the Asia-1 clade. Notably, 549H and 519I mutations in the hemagglutinin protein were observed, indicating adaptation to a non-canid wildlife species.
Conclusions
and Relevance: Overall, this study enhances our understanding of the molecular characterisation and evolutionary dynamics of the CDV strain present in the Malayan tiger and serves as a benchmark for developing effective preventative measures to protect Malayan tigers and mitigate their risk of extinction.

Background:
Dental records are essential repositories of patient information that support diagnosis, treatment planning, continuity of care, and medicolegal accountability, making them a fundamental component of safe, effective, and transparent dental practices. This study aimed to explore the perceptions and experiences of academic and nonacademic clinical staff regarding a paper-based patient record system at a Malaysian public dental institute.
Methods:
A qualitative phenomenological design underpinned by the sociotechnical systems theory was employed. Purposive sampling recruited 20 full-time staff (10 academic, 10 nonacademic) with at least 1 year of experience using the manual record system and no prior training in electronic dental records. Semi-structured, one-on-one interviews were conducted between May 2025 and October 2025, audio-recorded, transcribed verbatim, and analyzed using Braun and Clarke’s thematic analysis. Rigor was enhanced through independent coding, member checking, reflexive journaling, and adherence to the Consolidated Criteria for Reporting Qualitative Research checklist.
Results:
Four main themes were identified: (1) inefficiency and accessibility challenges; (2) accuracy, legibility, and record integrity; (3) continuity of care and patient safety risks; and (4) desire for digital transition and system improvements.
Conclusion
Although manual paper-based dental records remain central to documentation in teaching dental institutions, they present growing inefficiencies and safety concerns, highlighting the need for sociotechnical-informed strategies that align human processes, technology, and institutional support to enhance record-keeping and patient care.

Burkholderia cepacia complex (Bcc) is an emerging nosocomial pathogen, with violet-pigmented
strains representing a rare and possibly neglected but clinically important subset. We report a case
of a 62-year-old man with end-stage renal disease on dialysis who presented with fever and cough.
Blood cultures from central and peripheral lines grew violet-pigmented, non-lactose fermenting
colonies on MacConkey agar, later identified as Burkholderia contaminans sequence type 922 (ST922)
via a multimodal approach. Initial phenotypic methods (VITEK-2, API20NE and MALDI-ToF) and 16S
rDNA sequencing were inconclusive; however, multilocus sequence typing confirmed ST922, a strain
previously reported in India and associated with nosocomial outbreaks. The isolate was susceptible to
ceftazidime, trimethoprim/sulfamethoxazole, minocycline, and meropenem. The patient responded
well to intravenous ceftazidime, with subsequent blood cultures yielding no growth. Notably,
antimicrobial susceptibility varied geographically, with some ST922 isolates resistant to third-generation
cephalosporins. This case illustrates the diagnostic challenges in Bcc speciation and highlights the value
of molecular tools such as MLST. The detection of this strain in Malaysia raises concerns about global
dissemination, potentially via contaminated medical devices or water systems. Early recognition of
violet-pigmented Bcc in resource-limited settings can facilitate prompt, targeted treatment. This report
underscores the need for environmental surveillance and antimicrobial stewardship to prevent spread,
while reinforcing Bcc’s ecological adaptability and clinical significance, especially in immunocompromised
individuals.

Purpose:
This study evaluated the performance of the YOLOv8m-seg model in detecting and delineating interproximal caries and cervical burnout on bitewing radiographs and examined whether increasing the number of training epochs improved segmentation accuracy and consistency.
Materials and Methods:
In total, 1,410 bitewing radiographs were annotated using polygon-based masks by a trained dental clinician. The YOLOv8m-seg model was trained for 50, 100, and 150 epochs on 1,128 images and validated on 282 images using the Ultralytics segmentation framework. Model performance was assessed using precision, recall, and mean average precision at intersection-over-union thresholds of 0.5 and 0.5 to 0.95 (mAP0.5, mAP0.5-0.95) for both bounding box and mask outputs. Additional evaluation was conducted on a non-augmented validation subset.
Results:
Extended training duration was associated with improved segmentation performance. The highest mask mAP0.5-0.95 value was 0.828 at epoch 150. Both box-based precision and recall increased with longer training, whereas mask-based evaluation more accurately reflected the model’s ability to delineate the boundaries of caries and cervical burnout. Performance appeared consistent across both classes in the augmented validation split but was reduced in the non-augmented validation subset.
Conclusion
The YOLOv8m-seg model demonstrated high diagnostic accuracy in distinguishing proximal caries from cervical burnout on bitewing radiographs. Its mask-based outputs may assist clinicians in early lesion recognition and support improved diagnostic decision-making. Future studies should evaluate model generalizability across broader populations and diverse clinical environments and should prioritize assessment using non-augmented validation sets and independent test datasets.

Voltage-gated sodium channels (VGSCs) play pivotal roles in cancer progression and
have emerged as promising therapeutic targets and biomarkers. VGSCs comprise
multiple subtypes with distinct tissue distributions, influencing tumour characteristics in
different ways. Among these, the tetrodotoxin-sensitive α-subunits and the β1 subunit,
commonly found in breast cancer, have been implicated in metastasis and tumour
aggressiveness. The NaV1.5 channel and its neonatal variant (nNaV1.5) are
overexpressed in aggressive cancers such as breast, prostate, colorectal, and lung cancers,
thereby enhancing their invasive capacity. nNaV1.5 is particularly significant due to its
tumour-specific expression and strong association with poor prognosis, especially
in breast cancer, where it regulates cell proliferation, invasion, and tumour
microenvironment remodelling. This review highlights nNaV1.5 as a critical ion channel
that drives metastasis through ion regulation, extracellular acidification, and cytoskeletal
remodelling. We further evaluate current therapeutic strategies, including siRNA,
monoclonal antibodies, and small-molecule inhibitors, while addressing translational
challenges such as tumour heterogeneity, drug delivery limitations, and off-target
cardiotoxicity due to its similarity with the adult isoform. In addition, we explore the
potential of nNaV1.5 as a biomarker subject to epigenetic regulations by factors
including RE1-silencing transcription factor (REST) and histone deacetylase 2 (HDAC2),
which may facilitate patient stratification and treatment optimization. By integrating
mechanistic insights, therapeutic opportunities, and translational challenges, this review
goes beyond descriptive summaries to provide a framework for advancing nNaV1.5
research from preclinical studies toward clinical application in cancer therapy.

The use of Arabic in medical education and healthcare communication remains limited despite growing linguistic needs in Arabic-speaking populations. Issues related to translation accuracy, cultural sensitivity, and curriculum alignment hinder its integration. The objective of this study is to systematically review how Arabic medical terminology has been translated, validated, and applied in educational and clinical contexts. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Searches were conducted in May 2025 across three databases: Scopus, Web of Science (WoS), and the Education Resources Information Center (ERIC). A total of 769 records were retrieved, and 19 peer-reviewed articles were selected based on inclusion criteria. A six-point quality appraisal framework was applied to ensure methodological rigour prior to thematic synthesis. Three major themes emerged: (1) translation and cultural adaptation, highlighting the importance of expert validation and semantic accuracy; (2) psychometric evaluation, where tools such as the Postgraduate Hospital Educational Environment Measure (PHEEM) demonstrated strong internal consistency and contextual clarity; and (3) educational application, showing varied success in enhancing communication, comprehension, and learner confidence. Gaps in terminology standardisation and the limitations of automated translation tools were noted across studies. In conclusion Arabic medical terminology, when supported by structured processes and expert review, makes a meaningful contribution to education and communication. Further efforts should prioritise the development of validated terminology repositories, multidisciplinary collaboration, and the integration of Arabic-language resources into medical curricula to support inclusive and patient-centred care.

Introduction: Sleep quality has become a public health concern due to serious impacts on individual’s health outcomes. Thus, this cross-sectional study aimed to determine the sleep quality and its associated factors among adults living in the province of Terengganu, Malaysia. Materials and Methods: Socio-demographic information was self-reported whilst anthropometric measurements were measured by trained researchers. Sleep quality was assessed using the validated Pittsburgh Sleep Quality Index (PSQI) whilst eating behavior was measured using the Dutch Eating Behavior Questionnaire (DEBQ). Descriptive statistics and multivariable linear regression models were employed using IBM SPSS version 25.0. Results: A total of 580 participants were enrolled (mean age = 29.1 ± 10.0 years; 51.2% female), of which 74.7% (n = 433) had poor sleep quality (PSQI global score > 5) with a total sleep duration per night of 6.2 ± 1.6 hours. Gender (p-value=0.044), educational level (p-value=0.001), emotional level (p-value=0.005) and external eating (p-value=0.026) were significantly associated with poorer sleep quality. Conclusion: This study underscored the high prevalence of poor sleep quality among adults living in Terengganu, Malaysia. The findings could serve as a basis for developing sleep education strategies that are tailored to improve sleep quality among adults.

Introduction: Itch, an uncomfortable sensation leading to the urge to scratch, is often inadequately managed by conventional antihistamine drugs, which can be ineffective in certain pruritic conditions and cause undesirable side effects. Therefore, there is a need to identify new pharmacologically potent antipruritic compounds with fewer side effects. A synthetic curcuminoid analogue, 2,6-bis-(4-hydroxy-3-methoxybenzylidene)-cyclohexanone (BHMC), a derivative of curcumin - a bioactive compound found in turmeric - has demonstrated various pharmacological ac-tivities. Previous studies have shown that BHMC possesses antinociceptive and anti-inflammatory properties. This study aimed to investigate the antipruritic effects of BHMC in mice models of induced pruritus. Materials and Meth-ods: The pruritus in mice was induced using compound 48/80, substance P, histamine, and serotonin to establish an itch-induced mouse model. BHMC was administered intraperitoneally (i.p.) at doses of 0.1, 0.3, and 1.0 mg/kg. Results: BHMC significantly reduced pruriceptive responses in all models tested and notably inhibited compound 48/80 and substance P-induced mast cell degranulation in skin tissues. Conclusions: These findings suggest that BHMC inhibits pruriceptive responses in mice, likely through the inhibition of mast cell degranulation and/or direct antagonism of peripheral histamine and serotonin receptors. This may warrant further exploration of the antipruritic effect of BHMC in clinical trials for the betterment of animal and human health.
