    This study compared bite force in adults older than 60 years with that of young adults. The participants were 20 healthy adults (9 men) older than 60 years (median age, 66 years) and 44 healthy young adults (22 men; age range, 18-25 years; median age, 22 years) at the International Medical University, Malaysia. All participants had at least 20 teeth, and bite force was measured and evaluated using the Dental Prescale system. Average (SD) bite force was 420.5 (242.0) N for the older adults and 541.4 (296.3) N for the young adults. Although mean bite force was higher for the young adults, the difference was not significant. These findings suggest that bite force is unaffected by age in adults with adequate dentition.

    AIMS: The aim of this study was to establish 'Timed up and Go' test (TUG) normative data among community dwelling older adults stratified based on cognitive status, gender and age groups.

    METHODS: A total of 2084 community dwelling older adults from wave I and II were recruited through a multistage random sampling method. TUG was performed using the standard protocol and scores were then stratified based on with and without mild cognitive impairment (MCI), gender and in a 5-year age groups ranging from ages of 60's to 80's.

    RESULTS: 529(16%) participants were identified to have MCI. Past history of falls and medical history of hypertension, heart disease, joint pain, hearing and vision problem, and urinary incontinence were found to have influenced TUG performance. Cognitive status as a mediator, predicted TUG performance even when both gender and age were controlled for (B 0.24, 95% CI (0.02-0.47), β 0.03, t 2.10, p = 0.36). Further descriptive analysis showed, participants with MCI, women and older in age took a longer time to complete TUG, as compared to men with MCI across all age groups with exceptions for some age groups.

    CONCLUSION: These results suggested that MCI needs to be taken into consideration when testing older adults using TUG, besides age and gender factors. Data using fast speed TUG may be required among older adults with and without MCI for further understanding.

    BACKGROUND: The relationship between the activity of the epiphysis and gonads in rats of different sex and age in different seasons of the year was determined by studying the levels of melatonin and testosterone in the blood plasma. Determination of the levels of melatonin and testosterone in the serum of rats was carried out by enzyme-linked immunosorbent assay. To assess the relationship between the levels of melatonin and testosterone the correlation coefficient was calculated. Based on the study of the levels of melatonin and testosterone in serum the circannual relationship between the activity of the pineal gland and gonads in males of reproductive age has been determined. In females, the relationship between the levels of melatonin and testosterone without the circannual dependence has been determined. The strongest correlation between melatonin and testosterone is present in males at the age of 9 months in autumn, and it corresponds to the human age of 29-30 years.

    Giant cell tumor (GCT) of the bone is a benign, locally aggressive neoplasm that has a high tendency for local recurrence. It usually has a higher incidence in the third decade of life. This is a retrospective review of a case with histologic confirmation of GCT in a skeletally immature patient involving the metatarsal bone, which is a rare site. At our institution, 1.3% of skeletally immature patients had GCT of the bone. From an extensive literature review, only four cases of GCT of the metatarsal bone in the skeletally immature were identified. Giant cell tumor in a skeletally immature patient can be confused for an aneurysmal bone cyst because of similar radiologic findings. Giant cell tumor of the bone can occur in an immature skeleton and should be sought out as a differential diagnosis despite being rare.

    Breast cancer is the most common cancer among Malaysian women. Nonetheless, in Malaysia there is a marked geographical difference in the incidence of breast cancer with advanced stage of presentation. The breast clinic in Kuala Lumpur Hospital diagnosed approximately 150 to 200 new cases of breast cancer a year. This number, however, represents only 12.0% to 15.0% of all breast disease seen annually in Kuala Lumpur Hospital. Between 1998 and 2001, of a total of 774 cases of newly diagnosed breast cancer in Kuala Lumpur Hospital, only 5.0% (40/774) were impalpable breast cancers. The peak age group for the three major ethnic distributions (Malay, Chinese, and Indian) ranged from 40 to 49 years. The mean tumor size at presentation was 5.4 cm (range: 1-20 cm), and the advanced stage of breast cancer is observed to be highest among the Malay ethnic group. Although it appears that the incidence of breast cancer in Malaysia is lower than in the developed countries, the difference may be attributable to the difficulty in getting accurate statistics and to underreporting of cases. Nonetheless, from the available data, it is clear that breast cancer continues to be the most common cancer among Malaysian women. The strongly negative social-cultural perception of the disease, made worse by the geographical isolation of many rural areas, accounts for the delayed diagnosis and the often advanced stage of disease at presentation. A prospective population-based study is called for to verify the demographic patterns of breast cancer, particular in Malaysia and other developing countries. The findings of such a study may have implications for future breast screening programs and for facilitating the understanding of differing risks of breast cancer among women around the world.

    OBJECTIVES: Percutaneous coronary intervention (PCI) of total chronic total occlusion (CTO) still remains a major challenge in interventional cardiology. There is only insignificant knowledge reported in the literature about age differences in CTO recanalization. We analyzed in this study the issue of the impact of age on procedural characteristics, complications and short-term outcome.

    METHODS: Between 2012-2016 we included 440 patients. They underwent PCI for at least one CTO. Antegrade and retrograde CTO techniques were applied. The retrograde approach was used only after failed antegrade intervention. Continuous data are presented as the mean ± standard deviation; categorical data are presented as numbers and percentages unless otherwise specified. We used Twosamplet- t-test with equal variance to test the significant differences of the variables between the two cohorts.

    RESULTS: Procedural success proved independently of age. There was no significant interaction between age and procedural success (p=0.5). Complication rates were low in both groups (2.7% vs. 4%; p=0,4) with no difference in statistical significance.

    CONCLUSIONS: Our study suggests that in an aging society patients with severe coronary artery disease and chronical total occlusions an interventional therapy should be used more intensively. It can be performed safe and feasible.

    Larval age and nutrition significantly affected the insect's physiology. These influences are important when rearing a population of vectors that is used to monitor the resistance level, in which standardized conditions are crucial for a more harmonized result. Little information has been reported on the effects of larval age and nutrition on the susceptibility of insects to insecticides, and therefore, we studied the effects on the susceptibility of Culex quinquefasciatus Say's (Diptera: Culicidae) larvae to temephos by comparing the median lethal concentration (LC50) after 24 hr between the second and fourth instar larvae and between the larvae that fed on protein-based and carbohydrate-based larval diets. The susceptibility of the larvae was significantly affected by the larval diets, as the larvae that fed on protein-based beef food and milk food demonstrated significantly higher LC50 value compared with the larvae that fed on carbohydrate-based food: lab food and yeast food. The larval diet interacted significantly with the larval age: while the second instar larvae were susceptible to temephos when supplied with carbohydrate-based food, the second and fourth instar larvae had no significant effect when supplied with protein-based diets, implying that a protein-rich environment may cause the mosquito to be less susceptible to temephos. This study suggested the importance of standardizing nutrition when rearing a vector population in order to obtain more harmonized dosage-response results in an insecticide resistance monitoring program. Future research could focus on the biochemical mechanism between the nutrition and the enzymatic activities of the vector.

    We present a new set of subjective Age of Acquisition (AoA) ratings for 299 words (158 nouns, 141 verbs) in seven languages from various language families and cultural settings: American English, Czech, Scottish Gaelic, Lebanese Arabic, Malaysian Malay, Persian, and Western Armenian. The ratings were collected from a total of 173 participants and were highly reliable in each language. We applied the same method of data collection as used in a previous study on 25 languages which allowed us to create a database of fully comparable AoA ratings of 299 words in 32 languages. We found that in the seven languages not included in the previous study, the words are estimated to be acquired at roughly the same age as in the previously reported languages, i.e. mostly between the ages of 1 and 7 years. We also found that the order of word acquisition is moderately to highly correlated across all 32 languages, which extends our previous conclusion that early words are acquired in similar order across a wide range of languages and cultures.

    European standards on height, weight, centres of ossification and date of onset of puberty are not applicable to Asiatic girls in Malaya. " Asiatics " could not be grouped together, racial groups showed differences, especially the three main groups-Chinese, Indians and Malays. Nine tables are furnished showing the average and maximum and minimum heights and weights of the four main groups examined, as well as of some of the minor groups, arranged according to ages from 5 years to 19 years. The conclusion is drawn that the European standard of height and weight is higher than that of any of the Asiatic races in Malaya; a greater difference is noted in the weight than in the height and there is a much greater range in the weight of Asiatics but a smaller range in the height. Onset of menstruation tended to be earlier in the local Asiatic groups than in Europeans. The date of eruption of permanent teeth appeared to be earlier among Asiatic races. No deciduous teeth were found at the age of 12-13 years, the lower second molar was seen in all those examined at that age and the whole lower set was present, excluding the third molar. Earlier efuption of the canine teeth was also noticeable. Details should be consulted in the original by all those interested in medico legal work in tropical countries. P. A. Clearkin.

    BACKGROUND: The multimorbid burden and use of systemic immunosuppressants in people with psoriasis may confer greater risk of adverse outcomes of coronavirus disease 2019 (COVID-19), but the data are limited.

    OBJECTIVE: Our aim was to characterize the course of COVID-19 in patients with psoriasis and identify factors associated with hospitalization.

    METHODS: Clinicians reported patients with psoriasis with confirmed/suspected COVID-19 via an international registry, Psoriasis Patient Registry for Outcomes, Therapy and Epidemiology of COVID-19 Infection. Multiple logistic regression was used to assess the association between clinical and/or demographic characteristics and hospitalization. A separate patient-facing registry characterized risk-mitigating behaviors.

    RESULTS: Of 374 clinician-reported patients from 25 countries, 71% were receiving a biologic, 18% were receiving a nonbiologic, and 10% were not receiving any systemic treatment for psoriasis. In all, 348 patients (93%) were fully recovered from COVID-19, 77 (21%) were hospitalized, and 9 (2%) died. Increased hospitalization risk was associated with older age (multivariable-adjusted odds ratio [OR] = 1.59 per 10 years; 95% CI = 1.19-2.13), male sex (OR = 2.51; 95% CI = 1.23-5.12), nonwhite ethnicity (OR = 3.15; 95% CI = 1.24-8.03), and comorbid chronic lung disease (OR = 3.87; 95% CI = 1.52-9.83). Hospitalization was more frequent in patients using nonbiologic systemic therapy than in those using biologics (OR = 2.84; 95% CI = 1.31-6.18). No significant differences were found between classes of biologics. Independent patient-reported data (n = 1626 across 48 countries) suggested lower levels of social isolation in individuals receiving nonbiologic systemic therapy than in those receiving biologics (OR = 0.68; 95% CI = 0.50-0.94).

    CONCLUSION: In this international case series of patients with moderate-to-severe psoriasis, biologic use was associated with lower risk of COVID-19-related hospitalization than with use of nonbiologic systemic therapies; however, further investigation is warranted on account of potential selection bias and unmeasured confounding. Established risk factors (being older, being male, being of nonwhite ethnicity, and having comorbidities) were associated with higher hospitalization rates.

    Sixty-five patients with congenital kyphosis and kyphoscoliosis who underwent spinal arthrodesis are reviewed to determine the factors that influenced the outcome of arthrodesis. Mean follow up after surgery was 6 years and 6 months with all patients having a minimum of 2 years follow up. A satisfactory outcome, or a stable arthrodesis was defined as a loss of correction of less than 10 degrees from the time of surgery till review. An unsatisfactory outcome, or unstable arthrodesis was considered when there was more than 10 degree loss. Type of vertebral anomaly and type of arthrodesis procedure were significantly influenced stability of arthrodesis, whereas age when arthrodesis was performed and size of curve at surgery were not significantly related to stability of arthrodesis.

    Xanthine oxidase is a highly versatile enzyme which is widely distributed among various species. Though the presence of the enzyme in serum is not yet established, high antibody titre of this enzyme has been reported. Xanthine oxidase is thought to be the principal source of free radical generation via degradation of nucleotides to the end product, uric acid. The aim of this study was to detect xanthine oxidase activity in human plasma and report any significant relationships found between its activity and variables such as race, age and sex for the sample size studied. Forty six normal healthy individuals (14 males and 32 females) were studied. The enzyme activity was measured by a spectrophotometric method whereby the reduction of ferricytochrome c by free radicals was calculated and expressed as nmol O2 production/ml/min. Results obtained showed that there was a positive relationship between xanthine oxidase activity with age (r = 0.415, p < 0.05) and weight (r = 0.369, p < 0.05) in the normal individual. For the age group 30-39 yrs (n = 11), a higher enzyme activity was observed in males (2.71 +/- 1.44) as compared to females (2.34 +/- 1.23) but it was not significant (p = 0.53). For racial distribution, the Malays [M] have a higher enzyme activity (2.65 +/- 0.86, N = 32) than their Indian [I] (2.27 +/- 0.58; N = 7) and Chinese counterparts [C] (1.44 +/- 1.22; N = 7) but this was also not statistically significant (M vs I: p = 0.39; M vs C: p = 0.07; I vs C: p = 0.16). In conclusion this study showed that there is a measurable amount of xanthine oxidase activity in the human plasma.

    A total of 346 paediatric in-patients in the University Hospital in Kuala Lumpur was examined for infection with Enterobius vermicularis using two anal swabs taken on two consecutive days. 24% of these children. whose mean age was 6 years [range 2-14 years] were infected. The infection was more prevalent among children between the ages of 5-11 years. There is only a slight difference in the distribution of infection among Malay. Chinese and Indian children. There is no significant difference in the prevalance of infection between boys and girls.

    The characteristics of 74 patients who attempted suicide in Penang are described. Differences in the incidence and reasons for and methods of attempting were observed among the ethnic groups. There was a higher incidence in females and patients of single status. The majority of patients did not suffer from severe psychiatric disorders, but did encounter chronic inter-personal and intra-familial conflicts. Conflicts with elders were more frequent among female patients, and this finding suggested that young females were faced with a greater degree of role conflicts. Rural to urban shift among the Chinese patients was observed to be associated with a high incidence of attempts. Dwellers of high-rise flat complexes were not over-represented. In view of antecedent social factors, professionals and others besides psychiatrists have a role in the prevention and management of para-suicidal behaviours.

    This paper examines the effect of age at first calving and milking system on the overall lactation performance and incidence of lactation failure of 442 F1 Bos indicus/Bos taurus dairy crossbreds in Sabah. The two types of crossbred used in the study were imported F1 Sahiwal x Friesian and locally bred Friesian x Local Indian Dairy. Heifers which did not lactate for at least 120 days or produced less than 20 kg of milk during the fourteenth week of lactation were considered to have failed to establish a lactation. The imported and locally bred heifers recorded failure rates of 23.4 and 21.4% respectively. Three milking systems were examined namely machine milking without calf, machine milking with calf and hand milking. They produced failure rates of 30, 12 and 5.6% respectively. The cows that passed recorded 120 day milk production figures of 878, 1,134 and 1,054 kg respectively. The three age groups of less than 30 months, 30 to 34 months and greater than 34 months recorded failure rates of 37, 22 and 10% respectively. The heifers machine milked without their calf which calved at less than 30 months of age recorded a failure rate of 44% while those which calved at greater than 34 months recorded a failure rate of only 17%.
