PIP: In Peninsular Malaysia, while the female population aged 15-19 years registered a growth of some 240,000 persons between 1966-1984, the number of births occurring to teenage mothers has decreased by 15,176 from 33,348 to 18,172 during the same period. In 1966, teenage births constituted some 10.8% of the total births but has declined to 4.7% by 1984. A breakdown of the 1984 data by detailed age groups shows that only 0.9% of the teenage births had actually occurred among those below 15 years of age. The declining trend in teenage births, particularly the higher order births among the very young mothers, augurs well for the improvement in family welfare. However, in order to safeguard the health and welfare of mothers and children, concerted efforts should continue to be undertaken to integrate population, family health and family life education into the school curriculum.
PIP: In 1986, single puncture laparoscopic application of the Filshie clip was introduced into Malaysia's National Population and Family Development Board's female sterilization program for an evaluation. A total of 42 female sterilizations were performed by this method between June 1986 and December 1986. Laparoscopy was performed on an outpatient basis under local anesthesia. In 37 cases, the sterilization was interval. Filshie clips were successfully applied to the fallopian tubes of 40 women; in the remaining 2 cases, the latching mechanism jammed and Falope rings were used instead. The average time from application of 1st clip to skin closure was 10 minutes. During clip application, technical problems (faulty applicator, clip fell into the pelvic cavity, failure of latching mechanism) were encountered in 4 cases and surgical difficulties (poor visualization, hydrosalpinx, and tubal adhesions) occurred in 10 cases. In general, complications were minimal: 1 patient developed cynosis after anesyhesia (Pethidine) injection, the omentum was torn during introduction of the trocar in another, and a 3rd patient developed thrombophlebitis at the intravenous site. Only 1 pregnancy was recorded during the follow-up period; this occurred 15 months postoperatively and was intrauterine. Given the facts that this procedure is easy to learn, fast and simple, associated with no more complications than other laparoscopic procedures, and is cosmetically more acceptable to women, its more widespread application is recommended.
PIP: Previous studies have shown the users of intrauterine devices have a 4.4 times greater risk of pelvic inflammatory disease. This present study intends to categorize the distribution of microbes in cultures from different types of extracted copper intrauterine devices (IUCDs). Bacteriological studies of aerobic and anaerobic organisms were performed on the extracted IUCDs of 522 IUCD users; 480 wearing a Multiload Cu 250, 15 wearing a Copper T, 22 Lippes Loop and 5 a Copper 7. Cultures were negative in 46 (8.8%) IUCD cultures where 43 were Multiloads, Copper T (1) and Lippes Loop (2). 91.2% yielded bacterial growth and the commonest organisms isolated were Staphylococcus species, (23%), E.coli (9.6%) and Staphylococcus aureus (4.0%. Candida albicans, E.coli and Staphylococcus sp. were commonly isolated from Multiload, Copper T, Lippes Loop and Copper 7. Beta-hemolytic streptococci, Staphylococcus aureus and Candida sp. were frequently recovered from Multiload, Copper T and Lippes Loop. Only Multiload cultures yielded Bacillus, Streptococcus viridans, Klebsiella, Proteus, Enterobacter, Citrobacter diversus, Citrobacter freundii, Moraxella, Pseudomonas and Acinetobacter. One woman with complaint of PID yielded E.coli in her IUCD culture.
A cross-sectional study looking at the coagulation system was carried out involving 175 women attending the National Population and Family Development Board's Clinic at the Maternity Clinic, General Hospital, Kuala Lumpur. Study subjects comprise of 50 combined low-dose estrogen/progestrogen oral contraceptive (DC) pill users and 75 non-DC users, acting as controls. The subjects were on the pill for a period of one year or more. There were significant shortening of the prothrombin time (PT) and partial thromboplastin time (PIT) in the DC group as compared to the control group. However, the activities of factors II, Vand VIII assayed were not significantly different between the two groups, suggesting that the changes in the PT and PIT were not significant clinically. The effect of long term usage of combined 10w..cJose DC pills does not seem to indicate changes in the coagulation profile of the women in our study.
PIP: The effect of low dose combined oral contraceptives containing 30 mcg ethinyl estradiol and either 150 mcg levonorgestrel or 150 mcg desogestrel on coagulation indices in Malaysian women was examined. 50 women who had been using the pills for 1 year or more, were compared to 75 non-users. All were attending the Maternity Clinic of the General Hospital, Kuala Lumpur. Pill users registered shorter prothrombin time, 11.5 vs. 11.1 seconds (p=0.016), and partial thromboplastin time, 40.1 vs 35.1 seconds (p=0.000). Since there were no significant differences in Factors II, V, VII, or VIII, the overall effects of low-dose pills on coagulation is probably not clinically significant.
PIP: Between December 1990 and May 1991 in Malaysia, clinicians at the Sultanah Aminah Hospital in Johor Bahru screened 200 women with a diagnosis of threatened miscarriage with ultrasound to determine whether ultrasound could evaluate the viability of the fetus and thus the outcome of pregnancy in cases of threatened abortion. A fetal heartbeat was absent in 65% of cases with the remaining 35% of cases having a fetal heartbeat. Nonviability of the fetus or an abnormal or very early pregnancy may have accounted for an absent fetal heartbeat. The pregnancy of 46% of cases continued while 41% experienced spontaneous abortion. Just 6.2% of cases with a fetal heartbeat suffered from spontaneous abortion compared with 69.7% of those without a fetal heartbeat. 93.8% of cases with a fetal heartbeat continued their pregnancies compared with 30.3% of those without a fetal heartbeat. Inability of ultrasound to detect fetal heartbeats during early pregnancy probably accounted for the somewhat high percentage of those without a fetal heartbeat who continued their pregnancies. Among patients with a fetal heartbeat, the number of pregnancies that continued. Ultrasound detected 13% abnormal pregnancies (i.e., molar pregnancy or ectopic pregnancy). Surgery on these cases confirmed the ultrasound findings. These results showed that ultrasound should be used in every case of threatened miscarriage and that a fetal heartbeat does indicate the viability of the fetus.
PIP:
Health workers in Malaysia randomly assigned either a low-dose triphasic or a low-dose monophasic oral contraceptive (Triquilar and Marvelon, respectively) to 198 women to examine discontinuation rates and reasons for discontinuation. 15.3% of Triquilar women and 9.1% of Marvelon women forgot to take 1 pill at some time during the study while 6.1% and 3% forgot to take at least 3 consecutive pills. There were more complaints and/or complications among Triquilar women than among Marvelon women. The most serious complication was severe headaches (only 1 woman from each group). 2 women in the Marvelon group complained of either generalized itchiness or digestion impairment. Complaints of women in the Triquilar group included localized and generalized itchiness, weight gain, digestion impairment, dryness of vagina, and numbness of extremities. Women in the Triquilar group were more likely to have menstrual complaints than those in the Marvelon group (14.3% vs. 9.1%). The leading menstrual complaint in both groups was spotting (6.1% vs. 4%). No Marvelon women reported menorrhagia, scanty menses, or intermenstrual pelvic pain or discomfort while at least 1 woman did from the Triquilar group. The percentage of women with changes in complaints since admission were the same for both groups. Total discontinuation rates which included lost to follow ups were 46.9% and 40%, respectively. The most common reason for discontinuation for both groups was desired method change (11.2% Triquilar and 14.1% Marvelon). Method unrelated reasons (unable to return to clinic, moving/travel, and not interested in the study) were the next most common reason for discontinuation. 3 women conceived while taking Triquilar. These pregnancies were attributed to method failure, perhaps due to incomplete pituitary suppression. There were no accidental pregnancies in the Marvelon group.
PIP: To identify the maternal risk factors associated with low birth weight in Malaysia, the records of the 2613 infants delivered at North Okkalapa General Hospital from January to September 1990 were reviewed. The incidence of low birth weight during the 9-month study period was 21.1%; 18.1% of these cases were attributable to intrauterine growth retardation and 3% were associated with preterm births. Univariate analysis identified the following risk factors as significant: age under 20 years (.001), parity 1 (.001), maternal height of 145 cm or under (.01), maternal cigarette smoking (.01), maternal education of 8 years or less (.001), parity 5 or above (.05), and maternal age of 35 years and above (.05). A last birth interval of 1 year or less and more than 3 years was associated with an odds ratio exceeding 1, but the correlation with low birth weight was not significant. These risk factors should be used to design maternal health programs aimed at reducing the incidence of low birth weight.
PIP: Data from 297 interviews among married patients attending prenatal clinics in Malaysia in 1993 are used to determine the number, spacing, and timing of pregnancies. Only live born children are included. Findings indicate that 92.2% of women were 18-35 years old, 4.2% were under 18 years of age, and 3.6% were over 35 years old. 86.2% had 4 or fewer children and 13.8% had 4 or more children. 69.7% spaced children 2 or more years apart and 30.3% had birth spacing of under 2 years. Over 90% of women had their pregnancies during the ages of 18 and 35 years.
The widespread severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continuously impacts our economic and public health. The potential of emerging variants to increase transmissibility and evade vaccine-induced immunity lets us put more effort to research on viral mutations and explore the pathogenic haplotypes. In this study, we characterized the haplotype and sub-haplotype diversity of SARS-CoV-2 global variants in January-March and the areas with low and high COVID19 vaccination rates in May 2021 by analyzing viral proteome of complete genome sequences published. Phylogenetic tree analysis of the proteomes of SARS-CoV-2 variants with Neighbor-Joining and Maximum Parsimony methods indicated that haplotype 2 variant with nsp12 P323L and Spike D614G was dominant (98.81%), including new sub-haplotypes 2A_1 to 2A_3, 2B_1 to 2B_3, and 2C_1 to 2C_2 emerged post-one-year COVID-19 outbreak. In addition, the profiling of sub-haplotypes indicated that sub-haplotype 2A_1 with the mutations at N501Y, A570D, D614G, P681H, T716I, S982A, and D118H in Spike was over 58% in May 2021 in the high partly vaccinated rate group (US, Canada, and Germany). Meanwhile, the new haplotype 2C_3 bearing the mutations at EFR156-158del, T19R, A222V, L452R, T478K, and D614G in Spike occupied over 54.8% in May 2021 in the low partly vaccinated rate group (India, Malaysia, Taiwan, and Vietnam). Sub-haplotypes 2A_1 and 2C_3 had a meaningful alternation of ACE2-specific recognition site, neutralization epitopes, and furin cleavage site in SARS-CoV-2 Spike protein. The results discovered the haplotype diversity and new sub-haplotypes of SARS-CoV-2 variants post one-year pandemic in January-March 2021, showing the profiles of sub-haplotypes in the groups with low and high partly vaccinated rates in May 2021. The study reports the emergence of new SARS-CoV-2 sub-haplotypes during ongoing pandemic and vaccination in early 2021, which might help inform the response to vaccination strategies.
