Sociobiological risk factors for spontaneous abortion in Malaysia

Tan NH, Yahya A, Adeeb N

J Obstet Gynaecol (Tokyo 1995), 1995 Aug;21(4):313-8.
PMID: 8775898

OBJECTIVE: To evaluate the risk factors of spontaneous abortion.
METHODS: A case-control study was conducted by interviewing 350 women who were admitted to the university gynaecological unit for spontaneous abortion and 350 women who delivered normally at the university obstetric unit. Odds ratios, as the estimators of relative risks, were calculated.
RESULTS: The relative risk for spontaneous abortion among women in the age-group 30 to 39 years was 1.61 and among women above 40 years of age was 3.68 when compared to those below 30 years of age. In relation to career women, the relative risk of spontaneous abortion for housewives was 0.45. Ethnic group, parity, subfertility, previous induced abortion, ectopic pregnancy, contraception and menarcheal age did not influence the risk of spontaneous abortion.
CONCLUSION: Increasing age and a woman's career are significant risk factors of spontaneous abortion.

Fetal cerebral Doppler in the recognition of fetal compromise

Chandran R, Serra-Serra V, Sellers SM, Redman CW

Br J Obstet Gynaecol, 1993 Feb;100(2):139-44.
PMID: 8476805

OBJECTIVE: To establish reference ranges for the human fetal middle cerebral artery pulsatility index (MCA PI) for the local obstetric population, and to compare computerised antenatal fetal heart rate (FHR) analysis with the MCA PI as indicators of fetal compromise.
DESIGN: Prospective data collection for selected patients.
SETTING: High risk pregnancy unit of a teaching hospital.
SUBJECTS: Group 1 consisted of 18 healthy women with uncomplicated singleton pregnancies. Group 2 consisted of 27 women admitted to the high risk pregnancy unit over a 9 month period with intrauterine growth retardation and other related problems; all these women were delivered by prelabour caesarean section.
INTERVENTION: Serial Duplex sonography to determine fetal MCA PI in Groups 1 and 2. Serial FHR analysis using computerised numerical techniques in Group 2 only.
MAIN OUTCOME MEASURES: Serial MCA PI values from 24 to 39 completed weeks of gestation in Group 1. Comparison of serial MCA PI values with FHR analysis in relation to fetal outcome in Group 2.
RESULTS: In Group 1 the MCA PI diminished significantly as gestation advanced from 1.73 (SD 0.25) at 24 weeks to 1.38 (SD 0.26) at 39 weeks (P < 0.01). In Group 2 eleven babies were hypoxaemic at delivery: all had low MCA PI values while only nine had an abnormal FHR prior to delivery.
CONCLUSION: In normal pregnancy, there is a fall in the fetal MCA PI with advancing gestation which probably reflects a decreasing vascular resistance to fetal cerebral blood flow. Hypoxaemia at delivery appeared to be better recognised by the fetal MCA flow velocity waveform than the FHR analysis. This increased sensitivity, however, was achieved at the expense of a reduced specificity. Larger studies are needed to confirm the findings of this preliminary investigation.

Undescended testes: incidence in 1,002 consecutive male infants and outcome at 1 year of age

Thong M, Lim C, Fatimah H

Pediatr Surg Int, 1998 Jan;13(1):37-41.
PMID: 9391202 DOI: 10.1007/s003830050239

In a study of 1,002 consecutive Malaysian male newborns, 48 (4.8%) were found to have undescended testes (UDT). The rate and laterality of the UDT were associated with lower birth weight (P < 0.001) and prematurity (P < 0.001). Boys with UDT were also more likely to have other congenital abnormalities of the external genitalia, the commonest being hydrocele. No correlation between UDT and maternal age, birth order, social class, or mode of delivery was demonstrated in this study. Although 26/34 (76.5%) of UDT achieved full spontaneous descent by 1 year of age, 1.1% of all infants whose testes remained undescended required regular long-term follow-up with surgical referral and correction at an appropriate time. A premature infant with UDT is more likely to achieve full testicular descent at 1 year of age than a term infant.

Grandmultiparity in Malaysian women

Tai C, Urquhart R

Asia Oceania J Obstet Gynaecol, 1991 Dec;17(4):327-34.
PMID: 1801678

Grandmultiparity is an ill defined term, but it is generally believed that increasing parity after the fifth delivery increases the risks of child bearing for both the mother and fetus. Four hundred seventy-seven women aged less than 35 years of parity 5 and above who delivered during one year period at the University Hospital, Kuala Lumpur were studied. There were 406 women of parity 5 and 6 and 71 women of parity 7 and above. The 2 groups as a whole comprised 7.5% of the obstetric population for that year. Obstetric performance in the 2 groups of grandmultipara was compared with 1,135 women, aged 25 to 34 years, having their second baby during the same period. Women of parity 7 and above were significantly more likely to be from lower socioeconomic groups, and suffer from anaemia, hypertension and pre-eclampsia. They were also significantly at risk of preterm delivery and delivering infants weighing less than 2.5 kg. In addition, the perinatal mortality rate was significantly greater in the highly parous group (Para greater than 7) than in women of parity 5 and 6 or the control group. Apart from a significant increase in the incidence of anaemia, women of parity 5 and 6 had a similar obstetric performance and perinatal outcome to that of the control group. We conclude that grandmultiparity per se is not an obstetric risk factor until after the seventh delivery. These findings have implications for those who plan the provision of obstetric services for the community.

Fulltext Should neonates with specific "risk factors" be admitted to the special care nursery?

Yao SC, Chai MC, Singh A

Med J Malaysia, 1990 Mar;45(1):29-36.
PMID: 2152066

Existing criteria for admission of newborns to the special care nursery, Sarawak General Hospital, resulted in the admission of many neonates with certain risk factors ("at risk" neonates). To test whether such babies could be safely and better cared for in postnatal wards, 392 of these babies were randomly allocated into two groups. One group of 196 was admitted to the special care nursery and the other group of 196 was cared for with their mothers in the postnatal wards. The two groups were compared for mortality, morbidity and breastfeeding. There was no significant difference in mortality and morbidity between the two groups. While in hospital a larger proportion of babies cared for in postnatal wards were breastfed, compared to babies admitted to the special care nursery. In addition, they initiated their breastfeeding earlier. Babies with these risk factors should therefore be cared for with their mothers in the postnatal wards.

Mother's milk and sewage: their interactive effects on infant mortality

Habicht JP, DaVanzo J, Butz WP

Pediatrics, 1988 Mar;81(3):456-61.
PMID: 3344191

If they lived in households without piped water or a toilet, Malaysian infants who did not breast-feed were five times more likely to die after 1 week of age than those who breast-fed, when other significant factors affecting infant mortality were taken into account. This is double the relative risk associated with not breast-feeding for infants born into households with toilets, whether or not they had piped water. Analogously, improvements in toilet sanitation appear to have reduced mortality twice as much among infants who did not breast-feed as among those who did. These findings, from a retrospective survey of infants born to a probability sample of 1,262 women in peninsular Malaysia, confirm the pernicious synergistic effect of poor sanitation and nonbreastfeeding that was postulated previously on theoretical grounds. Promoting and maintaining high initiation of breast-feeding is thus particularly important where poor sanitation is prevalent. Even more affluent areas should not be neglected, however, because socioeconomic improvement, including improved environmental sanitation, is often accompanied by decreased breast-feeding. Although the risk to each nonbreast-fed infant was less in those areas, infants there were less likely to breast-feed in Malaysia, and hence they made up a significant proportion of lives that could be saved by breast-feeding.

Fulltext Current trends in the surgical management of coronary artery disease

Saw Huat Seong

Med J Malaysia, 1987 Dec;42(4):252-63.
PMID: 3331407

Coronary artery surgery as we know it today, has undergone rapid evolution since its introduction in the late 1960's, resulting, not surprisingly, in much confusion. In an attempt to present the state of the art, a collective review of the literature, coupled with the experiences with 118 patients is presented and discussed. The modern surgical management of patients with obliterative coronary artery disease is designed to relieve symptoms, prolong life and identify patients at high risk of premature death or myocardial infarction if they were to continue with medical management. Though the most common indication for surgery is persistent limitation of life style by severe symptoms, management is influenced by the strong association between such symptoms and increased mortality. During the short history of coronary bypass surgery, other indications for operation have been influenced by a combination of lessons from the past and hopes for the future. In addition, advances in technology have produced an enormous impetus for improvements in patient evaluation, surgical technique and postoperative care. As these advances continue and as more and more late results of surgery become available, answers to questions about surgery may increasingly be deduced from lessons rather than from hopes. As a result of these changes, an aura of confusion has gradually crept into the scene. It is hoped that this collective review, together with experiences gained from a personal series of 118 patients over a 3 year period from 1984 to 1986, will put into proper perspective, the state of the art of surgical management of coronary artery disease today.

Fulltext Soil-transmitted helminthiasis among children in Pulau Ketam, West Malaysia

Kan SP, Singh M, Singh S

Med J Malaysia, 1987 Mar;42(1):40-3.
PMID: 3431501

Only 8.4% of 1,286 Chinese boys and girls from the ages of 5-12 years in Pulau Ketam were infected with soil-transmitted helminths. The majority of these children had single infections with Trichuris or Ascaris alone. Mixed infections made up less than 5% of all infected cases. The worm burdens of infected children were very low. There was no definite pattern of distribution of infection among children of different ages and no differences in the distribution of infection between boys and girls. The main factors for the low prevalence and intensity of infection were the absence of suitable soil for the development and survival of infective helminth stages and the lack of contact with contaminated soil on this island. These two factors acted as very effective barriers to the transmission of soiltransmitted helminths on Pulau Ketam.

Fulltext Societal risk perception of death among workers in a security company in Malaysia

Jefferelli SB, Rampal KG, Aziz AJ, Agus Salim MB

Med J Malaysia, 2003 Dec;58(5):653-6.
PMID: 15190649 MyJurnal

How people perceive risk influences their behaviour towards these risks. We do not know how workers perceive risk of dying from diseases or accidents. This study was conducted among 198 workers of a security company in Malaysia. The workers were asked to score on a Likert scale of 1 to 5 the perceived risk of death of Malaysians from selected causes of death. The highest perceived risks of death were, in order of ranking, motor vehicle accidents, cancer and diabetes mellitus whereas according to the certified causes of death in Malaysia the highest risks of death among the selected items were cardiovascular disease, cancer and stroke. The difference in perception and mortality data needs be addressed.

Fulltext Vulnerability of the lower limb in non-fatal motorcycle injuries

Pang TY, Radin Umar RS, Harwant S

Med J Malaysia, 2001 Dec;56 Suppl D:9-11.
PMID: 14569759 MyJurnal

Motorcyclists form the highest group of fatalities on Malaysian roads. This is a prospective study conducted at 3 major hospitals for a period of 12 months to determine the type of motorcyclist injuries that usually required hospitalization. Four hundred and twelve consecutively injured motorcyclists were available for study. One hundred and eighty six (45.15%) were fatally injured and 226 (54.85%) were seriously injured and surviving. The main cause of fatalities was head injury, while lower limb injuries accounted for majority of hospitalizations. This study highlights the vulnerability of the motorcyclist to lower limb injuries.

Fulltext Are diabetic foot lesions precipitated by accidental trauma?

Doshi HK, Moissinac K, Harwant S

Med J Malaysia, 2001 Dec;56 Suppl D:29-33.
PMID: 14569763

Diabetic foot lesions may arise from frictional trauma due to tight or inappropriate footwear, repetitive stresses on parts of the foot, overlying bony prominence generated by walking and accidental trauma to the neuropathic foot. Many diabetics have been found to be unaware of their foot lesion, or know what the precipitating cause was. Based on the assumption that accidental trauma would affect the foot in a random fashion and result in lesions distributed evenly throughout the foot, a study was performed to determine whether foot lesions were distributed evenly or concentrated to certain areas of predilection. It was found that foot lesions were not evenly distributed but concentrated to certain areas of predilection. Even though relatively high proportion of the study population walked about in open slippers and barefeet, the study showed that accidental trauma was not a predominant precipitant of diabetic foot lesions. Diabetic foot lesions tend to occur as a result of cumulative, repetitive trauma to areas of prediliection rather than accidental trauma.

Fulltext Intestinal parasitic infections in man: a review

Norhayati M, Fatmah MS, Yusof S, Edariah AB

Med J Malaysia, 2003 Jun;58(2):296-305; quiz 306.
PMID: 14569755

Intestinal parasites of importance to man are Enterobius vermicularis, the soil-transmitted helminthes (STH)--Ascaris lumbricoides Tricburis trichiura, bookworms (Necator americans/Ancylostoma duodenale) and Strongyloides stercoralis and the protozoa Entamoeba histolytica and Giardia duodenalis. Other protozoa such as Cryptosporidium sp. and Isopora sp. are becoming important in causing prolonged diarrhea in immunocompromised patients. It is estimated that almost 1 billion, 500 million and 900 million people worldwide are infected by the major nematode species--A. lumbricoides, T. trichiura and hookworms respectively. Most of the infections are endemic and widely distributed throughout poor and socio-economically deprived communities in the tropics and subtropics. Environmental, socio-economic, demographic and health-related behavior is known to influence the transmission and distribution of these infections. In giardiasis, one study indicates that age < or = 12 years and the presence of family members infected with Giardia were risk factors for infection. Most of the infections occur in children and both genders are equally affected. Epidemiological studies of STH infections have shown that the prevalence and intensity of infection are highest among children 4-15 years of age. The frequency of distribution of STH infections is over-dispersed and highly aggregated. areas reinfection can occur as early as 2 months post-treatment, and by 4 months, almost half of the population treated become reinfected. By 6 months the intensity of infection was similar to pretreatment level.

Fulltext Relationship of objectively measured physical activity and sedentary behaviour with health-related quality of life among breast cancer survivors

Nurnazahiah A, Shahril MR, Nor Syamimi Z, Ahmad A, Sulaiman S, Lua PL

Health Qual Life Outcomes, 2020 Jul 10;18(1):222.
PMID: 32650777 DOI: 10.1186/s12955-020-01478-x

BACKGROUND: Lack of physical activity throughout one's lifetime has been associated with obesity and it is also an important risk factor of breast cancer. This study aimed to determine the relationship between objectively measured physical activity and sedentary behaviour with health-related quality of life (HRQoL) among breast cancer survivors in the East Coast region of Peninsular Malaysia.
METHODS: A cross-sectional study involving 83 breast cancer survivors was carried out in two main government referral hospitals in the region. Participants wore the ActivPAL3™ microdevice physical activity monitor for seven consecutive days. The validated European Organization for Research and Treatment of Cancer Quality of Life Questionnaires (EORTC QLQ-C30) and Breast Cancer Supplementary Measure (EORTC QLQ-BR23) were used to measure their HRQoL. Multiple linear regression analysis was conducted to determine the relationship between objectively measured physical activity and sedentary behaviour with HRQoL.
RESULTS: Longer time spent on moderate to vigorous physical activity (MVPA) was significantly associated with an improvement of HRQoL (p = 0.039) whereas longer time spent on sedentary behaviour significantly reduced the functioning score (p = 0.005). In addition, prolonged sedentary bouts were also significantly associated with better body image that led to improved HRQoL (p = 0.013).
CONCLUSIONS: The study findings suggest that an increase in the time spent on MVPA was associated with improved HRQoL while sedentary behaviour was associated with poorer HRQoL among breast cancer survivors. Thus, it is essential to displace sedentary behaviour with MVPA to improve the quality of life of breast cancer survivors.

Development and evaluation of a digital, community-based intervention to reduce noncommunicable disease risk in a low-resource urban setting in Malaysia: a research protocol

Kataria I, Ngongo C, Lim SC, Kocher E, Kowal P, Chandran A, et al.

Implement Sci Commun, 2020;1:87.
PMID: 33033807 DOI: 10.1186/s43058-020-00080-y

Background: Noncommunicable disease burden is rising in Malaysia, accounting for 72% of all deaths. Urbanization and globalization have contributed to changing patterns of diet and physical activity, creating an obesogenic environment that increases noncommunicable disease risk, especially in low-income populations. Community-based and technological interventions can play an important role in addressing structural determinants that influence noncommunicable disease burden. The Better Health Programme Malaysia aims to co-create and develop a community-based digital intervention for low-income populations to enable community stakeholders to address obesogenic environments and improve people's knowledge, attitudes, and practices related to noncommunicable disease risk.
Methods: This quasi-experimental study will assess community member and community health volunteer knowledge, attitudes, and practices on noncommunicable disease prevention, risk factors, and health-seeking behavior in three geographical areas of Kuala Lumpur, each representing a different ethnicity (Malay, Indian, and Chinese). Assessment will take place before and after a 9-month intervention period, comparing intervention areas with matched control geographies. We plan to engage 2880 community members and 45 community health volunteers across the six geographic areas. A digital health needs assessment will inform modification of digital health tools to support project aims. Intervention co-creation will use a discrete choice experiment to identify community preferences among evidence-based intervention options, building from data collected on community knowledge, attitudes, and practices. Community health volunteers will work with local businesses and other stakeholders to effect change in obesogenic environments and NCD risk. The study has been approved by the Malaysian Ministry of Health Medical Research Ethical Committee.
Discussion: The Better Health Programme Malaysia anticipates a bottom-up approach that relies on community health volunteers collaborating with local businesses to implement activities that address obesogenic environments and improve community knowledge, attitudes, and practices related to NCD risk. The planned co-creation process will determine which interventions will be most locally relevant, feasible, and needed. The effort aims to empower community members and community health volunteers to drive change that improves their own health and wellbeing. The learnings can be useful nationally and sub-nationally in Malaysia, as well as across similar settings that are working with community stakeholders to reduce noncommunicable disease risk.
