    BACKGROUND: Aspirin resistance has posed a major dilemma in the prevention of cardiovascular disease and stroke. There have been many factors that have been associated with aspirin resistance. Among these factors, the inflammatory processes of diabetes and glycaemic control have been significantly associated with aspirin resistance. Our study evaluated the prevalence of aspirin resistance and its associated factors.
    METHODS: This was a cross-sectional, interventional study, which was implemented from October to November 2012 at the Hospital Universiti Sains Malaysia (HUSM). Sixty-nine patients with diabetes who were taking aspirin were enrolled. The glycosylated haemoglobin (HbA1c) and C-reactive protein (CRP) levels were measured in these patients. The thromboelastography (TEG) level was measured using a TEG machine by a trained technician employing standard methods. The variables obtained were analysed for prevalence of aspirin resistance, HbA1c, CRP, and TEG level. The Chi-square test (and Fisher exact test where applicable) were used to evaluate the associations between aspirin resistance with glycaemic control (HbA1c) and inflammatory markers (CRP).
    RESULTS: The prevalence of aspirin resistance was 17.4% (95%; CI 9.3, 28.4). Glycaemic control (HbA1c) and inflammatory markers (CRP) were not associated with aspirin resistance. Aspirin resistance was prevalent in our study population and was comparable to other studies. The mean HbA1c in the aspirin-resistant group was 8.9%, whereas the mean HbA1c in the aspirin-sensitive group was 8.6%.
    CONCLUSION: There was no significant difference in HbA1c between the two groups. There was no significant association between CRP levels and aspirin resistance.

    We reviewed various studies regarding human toxoplasmosis in Malaysia. They showed a varying prevalence of specific Toxoplasma antibodies among the Malaysian population. The Malays have shown the highest seroprevalence of toxoplasmosis, by most studies, when compared to other races. Demographic profiles have shown that Toxoplasma seropositivity is higher in males than females, lower in people with higher incomes, higher in the unemployed and tends to increase with age. In general, the route of transmission, such as contact with a cat, consumption of undercooked meat and blood transfusion were shown to have no significant association with Toxoplasma seropositivity (p > 0.05). The immune status (CD4 cell count < 200 cell/mm3) was strongly associated with toxoplasmic encephalitis (p < 0.05).

    To determine the risk factors associated with complain of low back pain. A cross sectional study was done from June 2004 until August 2005. Seven hundred and sixty commercial vehicle drivers from 11 bus companies in central, northern and eastern regions in Malaysia participated in this study. Modified Nordic questionnaire was used to determine the prevalence of low back pain; Maestro human vibration meter was used to measure the personal R.M.S values of lateral, anterior-posterior and vertical axes. Modified Owas was used to assess the awkward posture of the driver torso namely, bending forward movement, leaning, sitting straight and twisting. Profile of Mood States (POMS) was used to evaluate the mood states of bus drivers with complain of low back pain. A high prevalence of low back pain (60.4%) among Malaysian commercial vehicle drivers was found. Logistic regression analysis controlling for age, income, education level and non occupational activities revealed that the following factors were related to low back pain: Tension-anxiety [1.080, 95% CI 1.041-1.121], depression dejection [1.047, 95% CI 1.023-1.072], anger-hostility [1.053, 95% CI 1.027-1.081], fatigue [1.132, 95% CI 1.089-1.177] and confusion [1.114, 95% CI 1.061-1.169] of POMS, length of employment [1.001, 95% CI 1.0-1.003], steering wheel adjustment [1.521, 95% CI 1.101-2.101], perception of exposing to vibration [1.943, 95% CI 1.389-2.719]. In conclusion, combinations of risks lead to high increase of low back pain complain among Malaysian bus drivers.

    BACKGROUND/OBJECTIVES: The purpose of the study was to investigate the relationship between household food insecurity and nutritional status of children in low-income households. A cross sectional study involved a survey of households (n = 223) receiving the financial assistance.
    SUBJECTS/METHODS: Eligible mothers that fulfilled the inclusion criteria such as non-pregnant, non-lactating mothers, aged 18 to 55 years with their youngest children aged 2 to 12 years, were purposively selected. The Radimer/Cornell hunger and food-insecurity instrument was administered and children's height and weight were measured.
    RESULTS: About 16.1% of the households were food secure, while 83.9% experienced some kind of food insecurity. Out of food insecure category, 29.6% households were food insecure, 19.3% women were individual food insecure and 35.0% fell into the child hunger category. Education of the mother (P = 0.047), household size (P = 0.024), number of children (P = 0.024), number of children going to school (P = 0.048), total monthly income (P < 0.001), income per capital (P < 0.001), number of household members contributing to the income (P = 0.018) and food expenditure (P = 0.006) were significant risk factors for household food insecurity. The prevalence of underweight, stunting and wasting in children were 61.0%, 61.4% and 30.6% respectively. Based on multinomial logistic regression, children in food-insecure households were 2.15 times more likely to be underweight and three times to be stunted than children in the food-secure households.
    CONCLUSIONS: The findings suggest that household food insecurity is associated with the nutritional status of the children in the rural area of Northeastern Peninsular Malaysia.

    Thyroid cancer is the most common among all endocrine malignancies. The worldwide prevalence of goitre in the general population is estimated at 4-7 percent and the incidence of malignancy in goitrous thyroid is about ten percent. It is postulated that goitrous thyroid is a precursor lesion to the development of malignant thyroid diseases. As Sarawak is a state well known for endemic goitre, this study focused on establishing the incidence of thyroid malignancy among goitrous thyroid swellings.

    BACKGROUND: A study was undertaken to determine gastrointestinal (GI) parasites commonly found in Malaysia's non-human primates (NHP) living in three different types of populations (wild, urban, and captive) and the basis of major GI parasites of zoonotic importance.

    METHODS: A total of 308 samples was collected and microscopically screened from the NHP in the wild (n = 163), urban (n = 76), and captive (n = 69) populations. The samples were taken from 12 species of local NHPs.

    RESULTS: At least, 44 species of GI parasites comprising of protozoans (seven species), nematodes (26 species), cestodes (five species), trematodes (five species), and pentastomida (one species) were detected. There were no significant differences for the overall prevalence and no great differences in GI parasite species among the wild, urban, and captive NHP populations.

    CONCLUSION: The most common GI parasite was Ascaris spp. (49.7%), followed by Oesophagostomum spp. (26.9%), and 31 species discovered in this study are of known public health importance.

    AIM: The aim of this study was to investigate the prevalence of orgasmic dysfunction and the potential risk factors that may be associated with orgasmic dysfunction among women at a primary care setting in Malaysia.
    METHODS: A validated questionnaire for sexual function was used to assess orgasmic function. A total of 230 married women aged 18 to 70 years participated in this study. Their sociodemographic and marital profiles were compared between those who had orgasmic dysfunction and those who did not, and the risk factors were examined.
    RESULTS: The prevalence of orgasmic dysfunction in the primary care population was 51.9%. Women with orgasmic dysfunction were found to be significantly higher in the following groups: age >45 years, being non-Malay, having lower academic status, married longer, having more children, married to an older husband, and being at menopausal state.
    CONCLUSION: Women with infrequent sexual intercourse are less likely to be orgasmic (odds ratio = 0.29, 95% confidence interval = 0.11-0.74).

    OBJECTIVE: The objective of this study was to identify the characteristics of oral cancer among Malay patients in Hospital Universiti Sains Malaysia (HUSM), Kelantan.

    METHODS: A retrospective record review was conducted from August to December 2006 in HUSM. Of 133 patients with oral cancer diagnosed from 1986 to 2005, 118 were Malay. Data on socio-demographic background, high-risk habits practiced, clinical and histological characteristics, and treatment profile of the patients were obtained.

    RESULTS: Malay patients with oral cancer were predominantly elderly, aged 60 years old and above (51.7%) at the time of diagnosis, with a mean age of 58.1 years (SD 16.81). Most patients were males (64.4%) and the majority of them were married (83.9%). More than half (58.5%) had been smokers, and of those who smoked, 89.9% were males. Some had a betel quid chewing habit (22.9%) but none ever consumed alcohol. The majority of the patients (77.1%) were diagnosed at stage IV. The tongue was the most usual site involved (37.3%) and squamous cell carcinoma was the most common histological type seen (75.4%).

    CONCLUSIONS: The prevalence of oral cancer among Malay patients in HUSM is high (88.7%). It is predominantly found in elderly males and the majority of cases present at advanced stage.

    Purple urine bag syndrome (PUBs) is a rare and startling phenomenon of purple discolouration in the urine or urinary catheter and bag. It is reported in chronically debilitated elderly patients, mostly in women on long-term urinary catheters. Its prevalence is strikingly more common in nursing home residents. Several factors contribute to the formation of indigo (blue) and indirubin (red) pigments from a breakdown of dietary tryptophan, which stains the urine purple. These factors include constipation, dysmotility of the bowel, bowel bacterial overgrowth, dehydration, and urinary tract infection. The presence of purple urine may cause undue alarm to both the patient and the doctor. Thus, we present this case report on an 86-year-old woman, a nursing home resident on a long-term urinary catheter, who presented to the primary care clinic. Her urine cleared after antibiotic therapy, replacement of her urinary catheter, and supportive management, which included hydration and nutrition. In addition to these measures, reducing the time between urinary catheter changes was recommended to prevent recurrence of this condition.

    BACKGROUND: The recent epidemic of dengue fever (DF) in Malaysia was alarming. The treatment of DF remains supportive as there is no anti-viral agent or vaccine available as yet. Traditional and complementary medicine (T&CM) provides an alternative option for the treatment of DF but there is limited evidence with regard to its usage. The aim of this study was to determine the prevalence, types and predictor factors of T&CM usage among DF patients in the northeast region of Peninsular Malaysia.
    METHODOLOGY: This was a cross-sectional study of DF patients in the northeast region of Peninsular Malaysia who had been admitted to a tertiary centre from January 2014 until December 2015. Serologically-confirmed DF patients aged 18 years and above were randomly selected. Phone interviews were conducted to obtain information regarding the use of T&CM during hospitalisation. Notes were made regarding the prevalence and type of T&CM used. Binary logistic regressions were used to identify the predictor factors of T&CM usage.
    RESULTS: A total of 241 DF patients with a mean age of 36.62 (SD = 14.62) years were included. The estimated prevalence of T&CM usage was 84.6% (95%CI: 80.1%, 89.2%). The most common T&CM used were crab soup (85.3%), papaya leaf extract (64.2%) and isotonic drinks (61.8%). The significant predictors for T&CM usage were age [adjusted odds ratio (AOR) 0.97; 95%CI: 0.94, 0.99], tertiary education (AOR 3.86; 95%CI: 1.21, 12.32) and unemployment (AOR 2.55; 95%CI: 1.02, 6.42).
    CONCLUSION: The prevalence of T&CM usage in our population is high. Age, tertiary education and unemployment influence the use of T&CM.

    Demodicosis is an infestation of the skin with Demodex, an ectoparasite commonly found on the face. A cross-sectional study was conducted to detect the presence of the ectoparasite and the outcome of facial cleanser and moisturizer usage on its infestation. Universal sampling was performed among 390 medical students, age 20-25 years old in the Klang Valley of Malaysia. The biodata of the participants and information on the use of facial cleanser and moisturizer were obtained through questionnaire. Skin samples were obtained using both skin scraping and cellophane tape method and were subsequently examined directly by microscopy. The results show an overall prevalence of 17.2%. Males (21.5%) were affected more often than females (12.8%) (p = 0.022). There were no significant differences in the prevalence of the ectoparasite among different ethnic groups, age-groups and the presence of existing facial problems among the subjects. A lower infestation rate (11.45%) was found to be associated with the use of a moisturizer (p = 0.033). Both species of ectoparasites that infest man, Demodexfolliculorum and D. brevis, were detected in this study either as single or mixed infestations.

    BACKGROUND: Alternating wet and dry seasons may play an important role in the acquisition and distribution of Blastocystis subtype infection in the tropics. This cross-sectional study was therefore conducted to provide the prevalence of Blastocystis and to determine the potential risk factors associated with each subtype during the wet and dry seasons in the Aboriginal community, Pahang, Malaysia.

    METHODS: A total of 473 faecal samples were collected: 256 (54.1%) and 217 (45.9%) samples were obtained during the wet (October-November 2014) and the dry season (June 2015), respectively. All fresh faecal samples were subjected to molecular analysis for subtype and allele identification.

    RESULTS: Of the 473 samples, 42.6% and 37.8% were positive for Blastocystis ST1, ST2, ST3 and ST4 during wet and dry seasons, respectively. Prevalence of Blastocystis ST1 was significantly higher during the wet season compared to the dry season (Z = 2.146, P

    A questionnaire survey on smoking was conducted among 395 medical students (40% males, 60% females) at the School of Medical Sciences, University Sains Malaysia at Kubang Kerian, Kelantan. Thirty-five students (9%), all of them males, were current smokers. Twenty-eight percent of the smokers smoked more than ten cigarettes per day and 88% began smoking before entering the medical school. Social influence and cigarette advertisements were the main reasons given for starting smoking. Both smokers and nonsmokers were adequately informed of the common adverse effects of smoking. Ninety percent of smokers had tried to give up smoking but failed. Among the ex-smokers and nonsmokers, the main reasons given for not smoking was that smoking was useless. Among the female students, one-third felt that cigarette smoking was socially unacceptable among females. This was one of the three main reasons for not smoking. Very few of the students (4.6%) considered that doctors' advice would play an important role in smoking prevention.

    Cystic Fibrosis (CF) is a life-threatening inherited disease that particularly affects the airways and digestive systems, which is caused by mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene. CF is considered as the most common autosomal recessive disorder in the Caucasian population. However, the prevalence of this disease amongst Asians is considered to be low, hence the lack of awareness of this disease amongst geneticists and physicians in Malaysia. This review will describe the features of CF, its molecular genetics, the current classification of CFTR mutation classes, the genotype-phenotype correlations, the effects of modifier genes, and the discourse of the disease pathogenesis, in the hope of raising public awareness of the condition and ultimately to improve the clinical and social care of those affected by CF in Malaysia.

    BACKGROUND: Fatigue is a typical consequence of cancer that can affect one's quality of life (QOL). The goal of this review is to provide comprehensive data on the impact of fatigue on QOL of cancer patients.

    METHODS: An electronic data search in Web of Science, SCOPUS, and PubMed for relevant papers; those written in English; those reporting quantitative data; and those including more than one hundred patients who received just chemotherapy were included. Studies involving participants that received other kinds of anti-neoplastic therapies were excluded.

    RESULTS: A total of 35 papers published between January 2000 and December 2021 were retrieved from the search databases of which (11612 patients) met the inclusion criteria. Findings showed that fatigue negatively affected QOL with a pooled prevalence of 49% (95% CI; 25.00-74.00) and the significant heterogeneity between articles was (I²=98%, P <0.001). Further, breast cancer contributed to the majority of selected articles with about 55 % (95%CI; 9:00- 94:00), followed by cancer (unspecified) 44% (95%CI; 5:00 - 92:00). Most studies (71%) (95%CI; 4:00 - 99:00) used the brief fatigue inventory (BFI) tool to assess severity of fatigue and 39% (95%CI; 17:00 -68:00) employed the European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire to evaluate QOL among cancer survivors.

    CONCLUSION: The prevalence of fatigue in cancer patients is high and fatigue has a negative impact on QOL of cancer patients receiving chemotherapy. Directionality, fatigue needs to be addressed and treated properly for better improvement of health status and QOL in cancer patients.

    Background: Growth faltering in early life can adversely affect health in later childhood and adulthood. Growth monitoring of children can provide evidence to help formulate effective strategies to address growth problems but such information on Palestinian children is lacking.

    Objectives: This study aimed to determine the growth patterns of children under 2 years in Gaza, Palestine.

    Methods: This retrospective cohort study was conducted in 2014 in 10 randomly selected primary health care clinics in 5 governorates of Gaza. Weight and length data were obtained from the health cards of children born in 2012, and z-scores were calculated and compared with the WHO Growth Standard (2006).

    Results: A total of 2 632 children's cards were included at the beginning of the study. Weight-for-age and weight-forlength decreased from birth to 6 months to about -0.40 SD but increased afterwards to -0.11 SD and 0.34 SD at 24 months respectively. Length-for-age declined after 6 months, reaching -0.85 SD at 24 months. At 6 months, the prevalence of underweight and stunting were 5% and 9% but at 24 months, the prevalence was 4% and 20% respectively. Wasting was highest at 6 months (10%) but decreased to 3% at 24 months. Significantly more girls were stunted at 9, 12 and 18 months (P < 0.001), underweight at 24 months (P < 0.05) and wasted at 12 months (P < 0.05). Early life faltering in length was more pronounced than weight, with stunting occurring in one fifth of boys and girls by 2 years of age.

    Conclusions: Preventive strategies are urgently needed to address early life causes of undernutrition, particularly stunting, in Palestinian children in Gaza.

    Annual and biannual mass single dose diethylcarbamazine citrate (DEC) at 6 mg/kg body weight was administered to people in a Brugia malayi endemic area in Shertallai part of Kerala, India, in 1987 and 1988. The coverage of population ranged between 41.33% and 66.01% in different rounds. The highest percentage of treated population developing side reactions was 8.4%. Both annual and biannual regimens were effective in reducing the microfilaria prevalence significantly from 4.90% to 1.23% and from 6.27% to 0.62% respectively and the incidence of infection was minimal in the adult population and zero among children. There was significant reduction in mean microfilaria count in both annual (81.08%) and biannual (98.00%) areas. Marked reduction in the proportion of high density carriers and infectivity index of the population after DEC therapy was also observed. Beneficial effect of mass single dose DEC on clinical cases of filariasis was evident from the reduction in the prevalence of acute manifestations, recent edema cases and the proportion of chronic cases with acute episodes. Results obtained from mass treatment areas were compared with those of the control area.

    The prevalence of antibody to human herpesvirus type 6 (HHV-6) and Epstein-Barr virus (EBV) viral capsid antigens (VCA) were analysed in sera from Kadazans of Sabah, North Borneo. At a serum dilution of 10, about 34% were positive for HHV-6 antibody but in contrast all 95 individuals studied were positive for EBV VCA antibody. The study shows that HHV-6 and EBV infection occur independently. The low frequency of seropositive individuals in this community suggests that other than socioeconomic factors are responsible for the spread of the virus.
