    This paper reported a preliminary study on Mat Rempit's activities and illegal motorcycle racing. Mat Rempit activities are becoming very popular among teenagers especially in major cities and towns in Malaysia. This phenomenon has created a new sub-culture amongst Malaysian teenagers. This study focused on psycho-social factors that encourage teenagers to involve in illegal motorcycle racing and to survey racing backgrounds (eg. racing types, time, places, prizes, etc.). Data was obtained through interview and live observations at the racing scene. One hundred racers and ex-racers had cooperated as respondents to feed this research with information. Results showed that Malay teenagers between 17-22 years old are the most involved in this activities. Also, moderating factors have been identified which are psychological factors where neurotic and extrovert personality traits and high level of self-esteem are found to correlate with racing involvement. Meanwhile, sociological factors such as peers, greatness flaunting culture and prizes are encouraging teenagers' involvement in illegal racing activities. Family and community roles to curb these unhealthy activities are suggested.

    The alpha haemoglobin stabilising protein (AHSP) acts as a molecular chaperone for α-globin by stabilising nascent α-globin before transferring it to waiting free β-globin chains. Binding of AHSP to α-globin renders α-globin chemically inert whereby preventing it from precipitating and forming reactive oxygen species byproducts. The AHSP has been actively studied in the recent years, particularly in its relation to β-thalassaemia. Studies have shown that AHSP is a modifier in β-thalassaemia mice models. However, this relationship is less established in humans. Studies by some groups showed no correlation between the AHSP haplotypes and the severity of β-thalassaemia, whereas others have shown that certain AHSP haplotype could modify the phenotype of β-thalassaemia intermedia patients. We investigated the expression of AHSP in relation to selected demographic data, full blood count, HPLC results, HbE/β-thalassaemia genotype, Xmn-1 Gγ polymorphism, α-globin, β-globin and γ-globin expression. We found that AHSP expression was significantly correlated to mean cell haemoglobin level, HbF %, α-globin, β-globin and excess α-globin expression. We concluded that AHSP could be a secondary compensatory mechanism in red blood cells to counterbalance the excess α-globin chains in HbE/β-thalassaemia individuals.

    Helicobacter pylori infection of a distinct subtype of cagA may lead to different pathological manifestation. The aim of this study is to determine the presence of cagA gene and its variants in H. pylori infection among different ethnic groups and its effect on gastroduodenal diseases. Overall detection of cagA among the 205 clinical isolates of H. pylori was 94%. Variations in size of the 3' region of cagA gene were examined among 192 Malaysian H. pylori cagA-positive strains. Results showed that three cagA variants differing in fragment length of PCR products were detected and designated as type A (621-651bp), type B (732-735bp) and type C (525 bp). Although there was no association between any of the cagA subtypes with peptic ulcer disease (p>0.05), an association between cagA subtypes with a specific ethnic group was observed. Specific-cagA subtype A strains were predominantly isolated from Chinese compared to Malays and Indians (p<0.0005), and cagA subtype B strains were predominantly isolated from Malays and Indians compared to Chinese (p<0.05). The cagA type A strains of H. pylori is commonly found in the Chinese patients who have a higher risk of peptic ulcer disease, thus indicating that it could be used as an important clinical biomarker for a more severe infection.

    Serum samples were obtained from 43 children 14 years old or younger in Malaysia and Guatemala. The levels of the serum glycoprotein alpha 2-macroglobulin (alpha 2-M) were assayed by two methods: the trypsin-binding assay of Ganrot (Clin. Chim. Acta 14:493, 1960) and a radial immunodiffusion assay against alpha 2-M antiserum. The two methods gave the same results. When serum alpha 2-M levels were plotted against serum vitamin A concentrations, they were significantly correlated (r = 0.505, P less than 0.001); children with serum vitamin A levels greater than 40 micrograms/100 ml had alpha 2-M levels of 3.71 +/- 0.79 mg/ml (mean +/- SD, n = 13), while those with level less than 40 micrograms/100 ml had alpha 2-M levels of 2.78 +/- 0.51 mg/ml (n = 30); the difference was significant (P less than 0.001). Normal, apparently healthy children had alpha 2-M levels of 3.90 +/- 0.39 mg/ml. Most of the children sampled suffered from a variety of infections; of these, measles appeared to counteract the effect of vitamin A deficiency by elevating alpha 2-M levels. Vitamin A-deficient children with measles had alpha 2-M levels not significantly lower than those of normal children. The difference between deficient and normal values of alpha 2-M was still significant (P less than 0.05) when expressed per milligram of serum protein, showing that the effect was not caused by lowered serum protein concentrations associated with protein-calorie malnutrition, from which most of the deficiency children suffered.

    The author describes changes in the size and characteristics of multiple-household compounds in Kelantan, Malaysia, during the period 1971-1991. It is found that "in Malay villages, multihouseholdcompounds were in earlier times...based on a bilateral residence rule in which one or more children, either male or female, would stay in the compound of their parents....A recent trend has been for more females to remain in the parental compound than males, reflecting the orientation toward independence among the males."

    Rotaviruses are the most common cause of viral gastroenteritis with the highest mortality and morbidity rates in children aged 0-5 years. The aim of this study was to determine the frequency of rotavirus infection in patients whose stool samples were sent to microbiology laboratory to investigate the etiology of diarrhea, to investigate the rotavirus genotypes that are common in our region and G10, G12 genotypes that have recently become common in the world. Fecal samples of 476 patients aged between 0-92 years who applied between November 2016 and February 2018 were studied via immunochromatographic rapid test and enzyme-linked immunosorbent assay (ELISA) methods. ELISA positive samples were studied by nested reverse transcriptase chain reaction (RT-PCR) and genotyped by agarose gel electrophoresis. Rotavirus was found positive in 18.3% and 17% of stool samples by immunochromatographic test and ELISA, respectively. All ELISA positive samples were also detected as positive by RT-PCR. 18.5% of female patients and 15.7% of male patients were found to be positive and rotavirus positivity was not statistically significant between genders. The frequency of rotavirus in different age groups was 23.5% (6-12 years), 17.3% (13-24 months) and 16% (25-36 months). It was determined that rotavirus cases were most common in the spring. G1, G2, G3, G4, G9, G10, and G12 were detected in 37%, 7.4%, 16.1%, 6.2%, 9.9%, 2.5%, 26% of the samples, respectively. G12 was the most common genotype after G1. The most common G and P genotype combination was G1P[8] (17.2%). This was followed by G12P[8] (11.11%) and G3P[8] (11.11%). P[8] (53%) was found to be the dominant P genotype. In this study, it was observed that rotavirus, which is the cause of childhood diarrhea, can also be encountered in advanced ages and even new genotypes that infect humans worldwide may also be the causative agents. Therefore, we concluded that it is important to investigate new genotypes such as G10 and G12 in molecular epidemiological studies.

    BACKGROUND: The Zuckerkandl's tubercle (ZT) of the thyroid gland is a well-described anatomical landmark, but few studies have clearly defined its association with pressure symptoms.

    METHODS: Sixty-six consecutive patients who had primary thyroid surgery were prospectively included in the present study between late January and early August 1998.

    RESULTS: A total of 96 capsular dissections were performed at thyroid surgery. Grades two and three ZT were recognized in 77 (80.2%) dissections. In general 49 (63.6%) of them were associated with significant pressure symptoms. In 43 (87.8%) of the dissections with pressure symptoms, grade 3 ZT was observed (mean weight of goitre: 154.8 g). Interestingly in this group, 16 (37.2%) patients with pressure symptoms had a goitre that was < 100 g and in one patient it was only 21 g.

    CONCLUSIONS: The pressure symptom of the thyroid gland does not always appear to be due to the large size of the goitre. In a relatively small-size goitre the ZT may cause significant pressure symptoms. Observations in the present study supported a strong association of enlarged ZT with pressure symptoms. We believe this is unlikely to be simply a coincidence but rather a consequence of the enlarged tubercle. Nonetheless a prospective randomized study is called for to allow meaningful and objective evidence to be drawn.

    PURPOSE: To evaluate the zonal differences in risk and pattern of pedicle screw perforations in adolescent idiopathic scoliosis (AIS) patients.

    METHODS: The scoliosis curves were divided into eight zones. CT scans were used to assess perforations: Grade 0, Grade 1( 4 mm). Anterior perforations were classified into Grade 0, Grade 1( 6 mm). Grade 2 and 3 (except lateral grade 2 and 3 perforation over thoracic vertebrae) were considered as 'critical perforations'.

    RESULTS: 1986 screws in 137 patients were analyzed. The overall perforation rate was 8.4% after exclusion of the lateral perforation. The highest medial perforation rate was at the transitional proximal thoracic (PT)/main thoracic (MT) zone (6.9%), followed by concave lumbar (6.7%) and convex main thoracic (MT) zone (6.1%). The overall critical medial perforation rate was 0.9%. 33.3% occurred at convex MT and 22.2% occurred at transitional PT/MT zone. There were 39 anterior perforations (overall perforation rate of 2.0%). 43.6% occurred at transitional PT/MT zone, whereas 23.1% occurred at concave PT zone. The overall critical anterior perforation rate was 0.6%. 5/12 (41.7%) critical perforations occurred at concave PT zone, whereas four perforations occurred at the transitional PT/MT zone. There were only two symptomatic left medial grade 2 perforations (0.1%) resulting radiculopathy, occurring at the transitional main thoracic (MT)/Lumbar (L) zone.

    CONCLUSION: Overall pedicle perforation rate was 8.4%. Highest rate of critical medial perforation was at the convex MT zone and the transitional PT/MT zone, whereas highest rate of critical anterior perforation was at the concave PT zone and the transitional PT/MT zone. The rate of symptomatic perforations was 0.1%.

    In 1977 and 1978 selected in-patients at the Tegalyoso Hospital, Klaten, Indonesia who had recent onsets of acute fever were serologically studied for evidence for alphavirus and flavivirus infections. A brief clinical history was taken and a check list of signs and symptoms was completed on admission. Acute and convalescent phase sera from 30 patients who showed evidence that a flavivirus had caused their illnesses were tested for neutralizing antibodies to several flaviviruses which occur in South-east Asia. Paired sera from seven patients demonstrated a fourfold rise in antibody titre from acute to convalescent phase. The most common clinical manifestations observed in this series of patients included high fever, malaise, stomach ache, dizziness and anorexia. None of the seven patients had headache or rash despite the fact that headache and rash had been associated with two of the three previously studied. The onsets of illness clustered toward the end of the rainy season when populations of Aedes aegypti, a probable vector in Malaysia, were most abundant.

    Youth–adult partnership (Y–AP) has emerged as a key practice for enacting two features of effective developmental settings: supportive adult relationships and support for efficacy and mattering. Previous studies have shown that when youth, supported by adults, actively participate in organizational and community decision making they are likely to show greater confidence and agency, empowerment and critical consciousness, and community connections. Most of the extant research on Y–AP is limited to qualitative studies and the identification of organizational best practices. Almost all research focuses on Western sociocultural settings. To address these gaps, 299 youth, age 15 to 24, were sampled from established afterschool and community programs in Malaysia to explore the contribution of Y–AP (operationalized as having two components: youth voice in decision-making and supportive adult relationships) to empowerment, agency and community connections. As hypothesized, hierarchical regressions indicated that program quality (Y–AP, safe environment and program engagement) contributed to agency, empowerment and community connections beyond the contribution of family, school and religion. Additionally, the Y–AP measures contributed substantially more variance than the other measures of program quality on each outcome. Interaction effects indicated differences by age for empowerment and agency but not for community connections. The primary findings in this inquiry replicate those found in previous interview and observational-oriented studies. The data suggests fertile ground for future research while demonstrating that Y–AP may be an effective practice for positive youth development outside of Western settings.

    BACKGROUND: Caregivers of elderly people need the right education and empowering skills to manage their own health needs and the elderly people they care for.

    OBJECTIVE: The study aimed to explore youth perceptions of the My-Elderly-Care-Skills Module intervention and its perceived feasibility.

    METHODS: This study involved youth respondents (18-30 years old) from low-income households who are accountable to providing care for independent older people (60 years or above) living in the same house. A qualitative study using a case study design was used to assess youth perceptions based on the content of the My-Elderly-Care-Skills module, by focusing on its implementation usage and usefulness for the care of the elderly. A total of 30 youths voluntarily participated in the online training workshop during the COVID-19 pandemic movement restriction order period. There were multiple sources of data, such as video recorded on reflection of care given at home, text messages in a WhatsApp group, and in-depth interviews during small group online meetings. Data were recorded and transcribed verbatim for common themes before a theme analysis was conducted. Inductive content analysis was performed after the saturation point was met.

    RESULTS: Thematic analysis derived two domains of feasibility: operational and technical feasibility. There were three themes under operational practicality (improving awareness, addressing the caregiving skills needs, and seeking resources for knowledge) and three themes for technical practicality (easily used and informative, skill in effective communication, and program fulfillment).

    CONCLUSION: It was verified that it is feasible for young caregivers of the elderly to participate in the My-Elderly-Care-Skills training intervention as it helps in improving knowledge and skills performance in managing and caring for the elderly.
