Saleh Huddin A, Md Yusuf N, Razak MRMA, Ogu Salim N, Hisam S

Infect Genet Evol, 2019 11;75:103952.
PMID: 31279818 DOI: 10.1016/j.meegid.2019.103952

It has been discovered that Plasmodium knowlesi (P. knowlesi) is transmitted from macaque to man. Thus, the aim of the present study was to determine P. knowlesi genetic diversity in both human (n = 147) and long-tailed macaque (n = 26) samples from high- and low-endemicity localities. Genotyping was performed using seven neutral microsatellite loci markers. The size of the alleles, multiplicity of infection (MOI), mean number of alleles (Na), expected heterozygosity (HE), linkage disequilibrium (LD), and genetic differentiation (FST) were determined. In highly endemic P. knowlesi localities, the MOI for human and long-tailed macaque isolates was 1.04 and 1.15, respectively, while the Na was 11.14 and 7.86, respectively. Based on the allele frequency distribution for all loci, and with FST

PMID: 31890106 DOI: 10.5704/MOJ.1911.004

Introduction: Proximal femur resection and endoprosthetic reconstruction is the preferred treatment for extensive bony destruction and pathological fractures. Due to the relatively high cost of endoprosthesis, we adopted the modified unipolar hemiarthroplasty (MUH) for reconstruction when the mode of treatment was for palliation. Materials and Methods: This is a retrospective case study of six patients, who had bone and multi-organs metastases with extensive proximal femur involvement with pathologic fractures who underwent resection and MUH reconstruction during the period 2013 to 2017. All patients were classified as Group B / C based on Scandinavian Sarcoma Group survival scoring, with estimated survival of maximum six months. The basic MUH construct consisted of Austin-Moore prosthesis which was secured to a Küntscher nail using cerclage wire and cemented into the femoral canal. Subsequently, the whole length of the prosthesis which remained outside the canal was coated with cement. Results: The mean age was 61.8 years. The mean survival was 3.9 months, post-operation. There was no implant failure during patients' life span; however, a third of the patients developed infection. Wheel chair ambulation was started immediately post-operation for all patients, and two patients progressed to walking frame ambulation. The total cost of each construct was below US$490 in comparison to long-stem hemiarthroplasty (roughly US$ 1700). Conclusion: Our aim was to alleviate pain, facilitate rehabilitation, ease nursing care and improve quality of life for metastatic bone disease patients until end of life. MUH for the treatment of pathological fracture in proximal femoral metastases is a feasible palliative surgical modality in resource-limited settings.
Low Immunologic Risk Living Related Renal Transplant Using Very Low-Dose Antithymocyte Globulin as Induction Therapy: A Single Tertiary Hospital Experience

The aim of induction therapy in the management of kidney transplant is to reduce the incidence of acute rejection and delayed graft function after kidney transplant. The agent for induction therapy differs depending on the recipient risks. The regimen can be either polyclonal (rabbit antithymocyte globulin [rATG]) or monoclonal antibody (basiliximab). Basiliximab is commonly used in patients with low immunologic risk. However, to date we know that the use of rATG on T cell depletion is dose dependent and more potent antirejection therapy. Therefore, we would like to look at 1-year graft function of very low-dose rATG in low immunologic risk recipients. All low immunologic risk patients who received low-dose rATG (0.5 mg/kg of body weight daily) during transplant (day 0) and on days 1 and 2 were recruited. Their renal function, HLA donor-specific antibodies, lymphocyte counts, protocol biopsy results, and cytomegalovirus (CMV) polymerase chain reaction were monitored as per clinical practice. All 10 patients had immediate graft function. Low-dose rATG caused lymphocyte counts to deplete immediately on day 0, and the effect lasted about 1 month post-transplant. All the patients had stable graft function without any significance episode of rejection. Only one patient had de novo HLA-DQ antibody. It is good to know that without prophylaxis antiviral in CMV+ donor to CMV+ recipient, the incidence of CMV viremia is considerably low in our cohort. Very low-dose rATG is an effective induction immunosuppression in low immunologic risk patients with acceptable infection risk.

PMID: 32440379 DOI: 10.7759/cureus.7732

Most patients with sinonasal carcinoma present to the otorhinolaryngologist with nasal symptoms. It is however uncommon for them to present with acute visual loss at first presentation. We report a case of compressive optic neuropathy secondary to sinonasal carcinoma, which presented acutely with right eye blurring of vision upon waking up. Computed tomography (CT) of the brain and orbit with contrast showed a locally invasive nasopharyngeal mass extending into the right orbit and cranial fossa. Histopathological examination revealed squamous cell sinonasal carcinoma. Her visual acuity improved with a three-day course of pulsed intravenous methylprednisolone 1 g per day, followed by a gradual tapering dose of oral prednisolone (1 mg/kg/day).

Chng KL, Lai PS, Siew SF, Md Yaro SW, Mahmood MS

Malays J Pathol, 2020 Apr;42(1):99-105.
PMID: 32342937

INTRODUCTION: Methanol is a widely available chemical with a range of uses including as solvent, as a fuel, in chemical synthesis and anti-freeze preparations. Most of the cases are accidental exposures to drinking beverages contaminated with methanol.
MATERIALS AND METHODS: In mid-September 2018, there was a single outbreak of methanol poisoning in Malaysia especially involving the state of Federal Territory Kuala Lumpur and Selangor. There were 33 reported deaths suspected due to methanol poisoning in this current outbreak where 11 of them were brought in to the Institute of Forensic Medicine (NIFM), Kuala Lumpur. The last outbreak was in the year 2013 with 29 deaths reported out of 44 cases.
RESULTS: There were 3 cases (27.2%) died in hospital and the remaining 8 cases (72.8%) were found dead at home and were later brought in dead to the hospital. A full autopsy was carried out for each case. Autopsy findings, as well as lab results pertaining to cases that survived and directly brought in dead, were of a different spectrum.
CONCLUSION: Methanol related deaths are almost always as a result of greed. The running truism is 'methanol poisoning is a result of deliberate addition/adulteration with industrial methanol'. Prevention of the illegal production of methanol and methylated spirits should be established to curb this matter in the future.

Clinacanthus nutans is a well-known herb that has been used as an alternative and therapeutic medicine, however more selective C. nutans extracts are needed. In this study, leaves were extracted with 80% methanol and further fractionated with n-hexane, dichloromethane, chloroform, n-butanol, and aqueous residue. Subsequently, the total phenolic content (TPC), total flavonoid content (TFC), antioxidant scavenging activity, and antiproliferative effects on breast cancer (Michigan Cancer Foundation-7 [MCF7]) and normal breast (Michigan Cancer Foundation-10A [MCF 10A]) cells of the extracts were measured. Additionally, molecular docking simulation of the major compounds from C. nutans extracts was conducted. The aqueous residue had the highest TPC and TFC, whereas the crude extract had the highest scavenging activity. Among the extracts, dichloromethane extract (CN-Dcm) was selected as it had the highest selectivity index (SI) (1.48). Then, the chosen extract (CN-Dcm) was proceed for further analysis. The compounds from CN-Dcm were identified using gas chromatography-mass spectrometry (GC-MS). The major compounds from CN-Dcm were further investigated through molecular docking studies. Palmitic acid and linolenyl alcohol were the compounds found in the CN-Dcm extract that exhibited the highest binding affinities with p53-binding protein Mdm-2. These results highlight the potential of C. nutans as a source of anticancer activities.

Environmental awareness and trends to develop sustainable resources have directed much research attention towards kenaf fibre as an alternative reinforcement in composite manufacturing. Numerous studies have been conducted on kenaf and its hybrid composites. Most studies were conducted on kenaf/glass hybrid composites compared to other kenaf/synthetic hybrid composites. Similar with other materials, mechanical properties were the fundamental knowledge identified by the researcher. Limited studies conducted on other properties have restricted the use of kenaf composites to non-structural applications. To extend the potential of kenaf composites to automotive exterior or other critical applications, studies on impact properties can be a valuable contribution in the material field. This review discusses the mechanical and low velocity impact properties of kenaf/glass hybrid composites reported previously. Percentage loading of fibre, the angle of orientation in woven fibres and the chemical treatment applied to the fibre before compounding are the three major parameters that affect the mechanical and impact properties of the composites. This review provides insights into the mechanical and impact properties of kenaf/glass hybrid composites for future research.

Mohd Salehuddin NS, Md Daud MK, Nik Othman NA, Abd Rahman N

Laryngoscope Investig Otolaryngol, 2021 Oct;6(5):1137-1141.
PMID: 34667858 DOI: 10.1002/lio2.651

Objectives: To determine the association between extended high frequency hearing loss and tinnitus in normal cochlear function based on a conventional audiometry chronic suppurative otitis media (CSOM) patient.
Design and methods: A cross-sectional study was conducted on 220 ears diagnosed as having CSOM with an equal number of tinnitus and without tinnitus groups. Only those with normal cochlear function based on conventional pure tone audiometry (250 Hz to 8 kHz) were included. They were further tested for hearing at extended high frequencies of up to 16 kHz. The severity of tinnitus was tested using a tinnitus questionnaire.
Results: The prevalence of extended high frequency hearing loss in the normal cochlear function CSOM patients with tinnitus was 81.8% (95% CI 74.5%, 89.1%), whereas the prevalence in the tinnitus negative group was 30.0% (95% CI 21.3%, 38.7%). There was a significant association between extended high frequency hearing loss and tinnitus in CSOM patients (P

Potential research outcomes on nanotechnology-based novel drug delivery systems since the past few decades attracted the attention of the researchers to overcome the limitations of conventional deliveries. Apart from possessing enhanced solubility of poorly water-soluble drugs, the targeting potential of the carriers facilitates longer circulation and site-specific delivery of the entrapped therapeutics. The practice of these delivery systems, therefore, helps in maximizing bioavailability, improving pharmacokinetics profile, pharmacodynamics activity and biodistribution of the entrapped drug(s). In addition to focusing on the positive side, evaluation of nanoparticulate systems for toxicity is a crucial parameter for its biomedical applications. Due to the size of nanoparticles, they easily traverse through biological barriers and may be accumulated in the body, where the ingredients incorporated in the formulation development might accumulate and/or produce toxic manifestation, leading to cause severe health hazards. Therefore, the toxic profile of these delivery systems needs to be evaluated at the molecular, cellular, tissue and organ level. This review offers a comprehensive presentation of toxicity aspects of the constituents of nanoparticular based drug delivery systems, which would be beneficial for future researchers to develop nanoparticulate delivery vehicles for the improvement of delivery approaches in a safer way.

Fadya Nabiha AS, Fam XI, Fatimah MN, Md Hud MZ

Med J Malaysia, 2021 Sep;76(5):774-776.
PMID: 34508395

Penile self-injections are performed with the purpose of increasing the size of the penis. Commonly, mineral oils or mineral oil-like substances are used for this purpose. However, there are very few publications describing on the complications from vegetable oil injections especially olive oil. Following the injection, the resulting deformity of the male genitalia is described as penile paraffinomas lipogranuloma of the penis. We would like to report a case of penis augmentation by a 50-year-old gentleman using olive oil injections that caused a massive, severely deformed of the penis and scrotum. Surgical excision and reconstruction was done. The patient was discharged after five days postoperatively, with full graft take. Injecting any oily substances into the human body is hazardous. The differential diagnosis of nodules following injections should be kept in mind and in doubtful cases, biopsy should be done. Regular follow-up is essential to prevent the further inflammatory event. Safe and legal procedures should be implemented for penile enlargement so as to avoid self-injections and in the prevention of such debilitating problems.

Fulltext Retinal Racemose Hemangioma With Optic Neuropathy in a Child

Ahmad Tarmizi NN, Bastion MC, Abdul Aziz RA, Md Din N, Mohd Khialdin S

Cureus, 2021 Aug;13(8):e17620.
PMID: 34646671 DOI: 10.7759/cureus.17620

The aim of this study is to report an unusual case of retinal racemose haemangioma (RRH) in a child resulting in optic neuropathy and its optical coherence tomography angiography (OCT-A) findings. This is a retrospective case report. For almost a year, a 13-year-old girl experienced gradual, painless, generalized blurred vision in her right eye. Visual acuity was 6/60 with a positive relative afferent pupillary defect (RAPD) in her right eye. The right-eye fundus showed enlarged and tortuous retinal vessels extending from the optic disc to all four quadrants, including the juxta foveal region. OCT analysis revealed distortion in the region of enlarged vessels with minimal retinal fluid while OCT-A of the macula area demonstrated dilated and tortuous vessels in the superficial layers of the retina. Right intra-orbital vascular channels surrounding the optic nerve with optic nerve atrophy and gliosis were detected on magnetic resonance imaging angiography/venography (MRA/MRV). The cerebral angiogram reported an abnormal tangle of small vessels within the right orbit that received supply from a dilated right ophthalmic artery indicating the presence of retro-orbital arteriovenous malformation (AVM). She was then referred to the neurosurgeon and a decision was made not to embolize or resect the dilated vessel as this might lead to occlusion of the ophthalmic artery and thus worsen her vision. RRH may present in the paediatric age group, and optic nerve atrophy is one of the disease manifestations. OCT-A is a less invasive diagnostic option compared to fundus fluorescein angiography (FFA) for diagnosis and monitoring of disease progression.

INTRODUCTION: The survival rate of female breast cancer survivors has been reported to be higher than other types of cancer in Malaysia. Nonetheless, breast cancer survivors face new challenges from unwanted side effects of treatment or management such as fatigue, psychological disturbance, or arm swelling, which can lead to the decline of quality of life (QOL). This study aims to adapt the Malay version of the Functional Assessment of Cancer Therapy-Breast (FACT-B) to evaluate the QOL and to test its reliability and validity in Malaysian breast cancer survivors.
METHODS: The Malay version of the FACT-B, with Disabilities of Arms, Shoulders and Hands (DASH), and Patient Health Questionnaire Anxiety-Depression Scale (PHQ-ADS) were distributed to female breast cancer survivors which were recruited on a voluntary basis, from cancer support groups based in selected states in Malaysia. Reliability was assessed based on internal consistency (Cronbach's α), whereas concurrent validity was examined by comparing domains in FACT-B with DASH and PHQ-ADS. Finally, total scores of each domain were analysed between lymphedema and without lymphedema groups for known-group validity.
RESULTS: A total of 113 breast cancer survivors agreed to participate (response rate = 100%) in the study. Our results showed that the Cronbach's α value for Malay FACT-B is 0.88, and each domain ranged from 0.62 to 0.88. A strong correlation was found between the physical well-being domain of FACT-B with DASH. Meanwhile, the breast cancer scale (BCS) displayed significant correlation with the instrument, Patient Health Questionnaire- Anxiety Depression Scale (PHQ-ADS), indicating that multiple factors including psychological distress were measured in the BCS domain. Furthermore, the instrument was able to detect differences in physical, functional and QOL between participants from lymphedema and without lymphedema groups.
CONCLUSION: The Malay version of the FACT-B demonstrated reliable properties and is effective in assessing QOL and can be applied in Malaysian breast cancer survivors.
Morphological and molecular identification of medically important questing Dermacentor species collected from some recreational areas of Peninsular Malaysia

Questing is a situation when a tick is seeking to get closer or ambush its potential host. However, information on questing tick species in Malaysia is still lacking, thus the association with tick-borne diseases (TBD) is not completely understood. The aim of this study was to investigate the tick species from five most frequently visited recreational areas in Pahang and Terengganu states, which were recorded to have high potential of TBD cases. By implementing handpick method, a total of 18 males and 15 females belonging to five Dermacentor Koch, 1844 species, were collected, namely D. compactus Neumann 1901, D. tricuspis (Schulze, 1933), D. auratus Supino 1897, D. steini (Schulze, 1933), and D. falsosteini Apanaskevich, Apanaskevich & Nooma respectively. The specimens were collected and identified based on morphological characters prior to obtaining the molecular data of COI and 16S rDNA. The D. compactus was the most abundant species collected in this study, while D. falsosteini was the least. All species were distinctly separated on the Neighbor Joining and Maximum Parsimony tree topologies and supported with high bootstrap values. Furthermore, a low intraspecific variation (0.00 - 0.01) was observed amongst the individuals of the same species in both genes. Meanwhile, each Dermacentor species was genetically different, with interspecific values ranging from 0.13-0.19 and 0.11-0.20 for COI and 16S rDNA. These findings had successfully recorded the tick species that were potentially associated with TBD, and which might be circulated among humans and animals. This study also has some implications on the diversity and geographical extension of Dermacentor ticks, thus should warrant further investigation as a potential vector of tick-borne diseases and public health importance.

Prostate cancer is currently diagnosed using the conventional gold standard methods using prostate-specific antigen (PSA) as the selective biomarker. However, lack of precision in PSA screening has resulted in needless biopsies and delays the treatment of potentially fatal prostate cancer. Thus, identification of glycans as novel biomarkers for the early detection of prostate cancer has attracted considerable attention due to their reliable diagnostic platform compared with the current PSA systems. Therefore, biosensing technologies that provide point-of-care diagnostics have demonstrated the ability to detect various analytes, including glycosylated micro- and macro-molecules, thereby enabling versatile detection methodologies. This highlight article discusses recent advances in the biosensor-based detection of prostate cancer glycan biomarkers and the innovative strategies for the conjugation of nanomaterials adapted to biosensing platforms. Finally, the article is concluded with prospects and challenges of prostate cancer biosensors and recommendations to overcome the issues associated with prostate cancer diagnosis.
Fulltext Risk factors for early TB treatment interruption among newly diagnosed patients in Malaysia

Suliman Q, Lim PY, Md Said S, Tan KA, Mohd Zulkefli NA

Sci Rep, 2022 01 14;12(1):745.
PMID: 35031658 DOI: 10.1038/s41598-021-04742-2

TB treatment interruption has resulted in delayed sputum conversion, drug resistance, and a high mortality rate and a prolonged treatment course, hence leading to economic and psychosocial affliction. To date, there are limited studies investigating the physico-social risk factors for early treatment interruptions. This prospective multicenter cohort study aimed to investigate the risk factors for early treatment interruption among new pulmonary tuberculosis (TB) smear-positive patients in Selangor, Malaysia. A total of 439 participants were recruited from 39 public treatment centres, 2018-2019. Multivariate Cox proportional hazard analyses were performed to analyse the risk factors for early treatment interruption. Of 439 participants, 104 (23.7%) had early treatment interruption, with 67.3% of early treatment interruption occurring in the first month of treatment. Being a current smoker and having a history of hospitalization, internalized stigma, low TB symptoms score, and waiting time spent at Directly Observed Treatment, Short-course centre were risk factors for early treatment interruption. An appropriate treatment adherence strategy is suggested to prioritize the high-risk group with high early treatment interruption. Efforts to quit smoking cessation programs and to promote stigma reduction interventions are crucial to reduce the probability of early treatment interruption.
Tocotrienols protect differentiated SH-SY5Y human neuroblastoma cells against 6-hydroxydopamine-induced cytotoxicity by ameliorating dopamine biosynthesis and dopamine receptor D2 gene expression

Oxidative stress is a critical factor that triggers a "domino" cascade of events leading to the degeneration of dopaminergic neurons in Parkinson disease. Tocotrienols (T3) have antioxidant effects and can protect neuronal cells against oxidative damage. In the present study, we investigated the neuroprotective effects of different forms of T3 (alpha, delta, gamma) or tocotrienol-rich fraction (TRF) against 6-hydroxydopamine (6-OHDA)-induced oxidative damage in differentiated SH-SY5Y human neural cells. Differentiating the SH-SY5Y cells with retinoic acid and a low-serum culture medium for 6 days allowed development of human dopamine-like neural cells. Subsequently, the differentiated SH-SY5Y neural cells were pretreated with different forms of T3 for 24 hours before these cells were exposed to 6-OHDA. The T3 analogues and TRF displayed neuroprotective effects (P < .05) via restoration of cell viability and activation of antioxidant enzymes (e.g., superoxide dismutase, catalase). Notably, TRF was highly efficient in scavenging reactive oxygen species and upregulating dopamine and tyrosine hydroxylase levels in the differentiated SH-SY5Y cells. Gamma-T3 exhibited the most potent effects in attenuating apoptosis, whereas alpha-T3 was most effective in preventing 6-OHDA-induced leakage of α-Synuclein. Delta-T3 displayed a noticeable effect in upregulating the dopamine receptor D2 gene expression compared with controls. These findings suggest T3 isoforms and TRF demonstrate significant neuroprotective effects in protecting differentiated neural cells against 6-OHDA-mediated oxidative stress.

Leonard JH, Choo CP, Manaf MR, Md Isa Z, Mohd Nordin NA, Das S

Indian J Med Sci, 2009 Oct;63(10):445-54.
PMID: 19901483

BACKGROUND: There is a paucity of literature on validated outcome measurement tools for evaluation of neck pain and related disability in the Asian context.
AIM: The main aim of the present study was to design a new tool called neck pain functional limitation scale (NPFLS) for measuring disability related to neck pain and observe its reliability, concurrent validity and criterion validity.
SETTING AND DESIGN: This study was performed at the institutional hospital.
MATERIALS AND METHODS: A total of 157 subjects (neck pain group) and 25 control subjects (control group) without neck pain were recruited for this study. NPFLS was framed as a new tool for this study, which consisted of 5 domains - pain intensity, activities of daily living, social activities, functional activities and psychological factors. Neck Bournemouth questionnaire (NBQ) was used as a gold standard to measure the concurrent validity and criterion validity of the NPFLS.
STATISTICAL ANALYSIS: Criterion validity and concurrent validity between the neck Bournemouth questionnaire (NBQ) and NPFLS scores were tested statistically using Mann-Whitney U test and Spearman correlation test. The reliability was tested by examining the internal consistency to calculate the Cronbach's alpha value for each item in NPFLS.
RESULTS: No significant difference between NPFLS and NBQ was observed using Mann-Whitney U Test, with P value greater than 0.05 (P= 0.557). Besides that, NPFLS had a high concurrent validity (r= 0.916) and good internal consistency with high Cronbach's alpha value of (r= 0.948), which demonstrated strong correlation between the items of NPFLS and NBQ.
CONCLUSION: NPFLS demonstrated good reliability, high concurrent validity and criterion validity in this study. NPFLS can be used to assess neck pain and disability among patients with neck pain.
