The Department of Primary Care Medicine was established in UHKL in 1987. This article examines the philosophy of primary care, the clinical services provided by UHKL Family Practice Clinic and the quality assurance activities.
BACKGROUND: Physical inactivity remains the most important modifiable risk factor in preventing a variety of noncommunicable diseases (NCDs) and has been identified to be a risk factor for obesity, heart disease and cancers. This study examined the prevalence and factors associated with physical inactivity among the suburban adult population in Port Dickson district, Negeri Sembilan, Peninsular Malaysia.
MATERIAL AND METHODS: This was a community based cross-sectional study involving 397 adult respondents conducted in February 2016. Data was collected by face-to-face interview using a structured questionnaire. Data regarding socio-demographic factors (age, gender, ethnicity, education level, marital status and monthly income, working hours), current behavioural stage of physical activity and perceived benefits and barriers to physical activity were collected. Physical activity measured using the International Physical Activity Questionnaire (IPAQ) with the cut-off point of less than 600 met-min per week was considered to be physically inactive.
RESULTS: The prevalence of physical inactivity among adult population was 36.3%. Factors significantly associated with physical inactivity included age, gender, marital status, working hours and current behavioural stage of physical activity.
CONCLUSION: Physical inactivity is high among the adult community in Negeri Sembilan district, Peninsular Malaysia and was strongly associated with age, gender, marital status, working hours and current behavioural stage of physical activity. It is important to identify individuals with physical inactivity and its associated factors early as this could severely affect the quality of life of the individuals.
Study site: Six housing areas in Port Dickson District, Negeri Sembilan, Malaysia
Two major fruit fly pest species, Bactrocera dorsalis and B. umbrosa, are strongly attracted to methyl eugenol (ME) found in >450 plant species. They are, however, exclusive pollinators of certain daciniphilous (attracting Dacini fruit flies) Bulbophyllum orchids. A comparison between the recaptures of feral males after feeding ad libitum on 0.6 mg ME (simulating an average floral quantity of an orchid flower - Trial 1) and 480 mg in Trial 2 was investigated using the non-invasive capture-mark-release-recapture (CMRR) technique. Based on daily CMRR over a 16-day period, using a different colour enamel paint each day, percentages of B. dorsalis males recaptured in Trial 1 were significantly higher than those in Trial 2. However, for B. umbrosa, percentages of recaptures for different day-specific colours were highly variable due to low fly numbers captured/day. In Trial 1, of 756 B. dorsalis males released, 36.4% were recaptured once, 7.7 twice, 2.4 three times and 0.4 four times. While in Trial 2 of 1157 released males, 6% were recaptured once and 0.3% twice. Of 67 B. umbrosa males released, 28.4% were recaptured once and none more than once in Trial 1. Nevertheless, of 119 flies released in Trial 2, 25.2% were recaptured once and 3.3% twice. Overall, many marked males did return to a single ME-source to 'refuel' ME (a sex pheromone precursor). The results also show that a relatively high number of flies paid multi-visitations to a single 0.6 mg ME-source and indicate that the presence of natural ME-sources may impact area-wide IPM programmes.
FcgammaRIIs are the most widely distributed of the Fcgamma receptor family and play an important role in the clearance of immune complexes. Evidence that the FcgammaRIIa-R131 allotype is less able to process and clear immune complexes effectively suggests that this may be a disease susceptibility factor for systemic lupus erythematosus (SLE). Data from studies published thus far do not agree on the potential role of FcgammaRIIa polymorphism in the genetics of SLE. Most studies in fact show no evidence for any correlation between polymorphism of FcgammaRIIa and risk for SLE. However, it remains to be determined whether FcgammaRIIa polymorphism may play a critical role in certain groups of patients, especially in those of differing ethnic background. Polymorphism of FcgammaRIIa may also be important in determining disease phenotype, and identification of this influence may have important implications in patient care and in identifying patients for more aggressive therapy.
The quest for improving and maintaining sexual function has been going on since time immemorial. The advent of an effective oral drug, sildenafil, has brought about unprecedented open discussion on male erectile dysfunction, and gas accelerated the pace of development of new therapies for erectile dysfunction. New knowledge in the physiology of sexual function has enabled researchers to target drug treatment at the whole network of the central nervous system and the numerous cascadic enzymatic reactions leading to relaxation of the corporal smooth muscle. One of the brightest potential applications of future molecular technology in the study of erectile dysfuction is in the utilization of gene therapy.
The analyses of a few tasks were carried out in an electronics factory. The main objectives are to identify the ergonomic and biomechanical hazards of problem work tasks, to analyze each task systematically in order to evaluate the workers' exposures to the risk factors of force, posture pressure and repetition and to make recommendations to reduce the risks and hazards. The methodology includes objective measures--detailed analysis by going through training manuals, job description and production records. Subjective measures include interviewing the operator and supervisors informally, the operators were also required to fill in a structured questionnaire. The paper concludes by making recommendations to reduce the ergonomic hazards by engineering solutions, redesign or administrative controls or the implementation of procedures.
This is a study of 13 Malaysian patients with clinically definite Multiple sclerosis (MS) subjected to a hot bath test with VEPs, BAEPs, median nerve SSEPs before and after heating. Five patients (38%) developed neurological changes with the rise in body temperature. There was an average of 0.46 new sign per patient. Four patients had motor disturbances attributed mainly to aggravation of spinal cord dysfunction. Two patients had additional visual deterioration, one patient has associated VEP change. This study shows that though Uhthoff's phenomenon has not been noted in the reports of Asian MS patients, when subjected to rigorous testing, Asian MS patients also show sensitivity to body temperature change. However, the percentage of positivity of the hot bath test is much lower than that reported for Caucasians. Thus this study shows further differences between Asian and Caucasian MS patients.
Reconstruction surgery for a female to male transsexual usually involves mastectomy, hysterectomy and creating an aesthetically appealing neophallus. We have successfully inserted an inflatable prosthesis using the AMS CX prosthesis in a 45 year old transsexual, who had a large bulky neophallus constructed from the anterior abdominal subcutaneous fat, about 9 years ago. The single cylinder CX prosthesis was well anchored to the symphysis pubis using a dacron windsock tubing, the activation pump was placed in the dependent pouch of the right labium and the reservior in the usual perivesical space. The patient subsequently had debulking procedure using liposuction to create a more aesthetic and functional phallus. To date, the inflatable neophallus prosthesis is functioning well.
