PMID: 31079127

INTRODUCTION: Short Interpregnancy interval (IPI) is defined as the interval between the live birth outcome and the next pregnancy conception of less than 24 months. It has been linked to adverse maternal and perinatal outcomes. The objective of this study was to determine the prevalence and the predictors of short IPI among antenatal mothers.
METHODS: A cross-sectional study was conducted among 452 antenatal mothers attending health clinics in Klang in April 2018. Probability sampling was used and data was collected by using a validated self-administered questionnaire. The dependent variable of the study was short IPI and the independent variables were sociodemographic, obstetric history and planning of pregnancy. Analysis of data collected in the study was performed by using IBM Statistical Package for Social Science (SPSS) version 24.
RESULTS: The prevalence of short IPI found in this study was 48%. Seven identified predictors of short IPI were: age less than 25 years old (Adjusted Odd Ratios; AOR 12.16, 95%CI: 4.72, 31.30), age of 26 to 30 years old (AOR 5.20, 95%CI: 2.62, 10.32), age of 31 to 35 years old (AOR 2.90, 95% CI: 1.50, 5.64), higher education (AOR 2.11, 95% CI: 1.34, 3.34), parity more than three (AOR 3.12, 95% CI: 1.42, 6.84), irregular menstruation (AOR 2.17, 95% CI: 1.40, 3.37) and unintended pregnancy (AOR 2.88, 95% CI: 1.88, 4.40).
CONCLUSION: Innovative programmes, for example by making IPI information available through online resources, could effectively target young mothers as the younger generation prefers quick, easily-accessible and reliable information.

In this work, hydrolysis of cellulose and hemicellulose content of palm kernel cake (PKC) by different types of hydrolytic enzymes was studied to evaluate monomeric sugars released for production of biobutanol by Clostridium saccharoperbutylacetonicum N1-4 (ATCC 13564) in acetone-butanol-ethanol (ABE) fermentation. Experimental results revealed that when PKC was hydrolyzed by mixed β-glucosidase, cellulase and mannanase, a total simple sugars of 87.81±4.78 g/L were produced, which resulted in 3.75±0.18 g/L butanol and 6.44±0.43 g/L ABE at 168 h fermentation. In order to increase saccharolytic efficiency of enzymatic treatment, PKC was pretreated by liquid hot water before performing enzymatic hydrolysis. Test results showed that total reducing sugars were enhanced to 97.81±1.29 g/L with elevated production of butanol and ABE up to 4.15±1.18 and 7.12±2.06 g/L, respectively which represented an A:B:E ratio of 7:11:1.

Catalytic depolymerization of mannan composition of palm kernel cake (PKC) by mannanase was optimized to enhance the release of mannan-derived monomeric sugars for further application in acetone-butanol-ethanol (ABE) fermentation. Efficiency of enzymatic hydrolysis of PKC was studied by evaluating effects of PKC concentration, mannanase loading, hydrolysis pH value, reaction temperature and hydrolysis time on production of fermentable sugars using one-way analysis of variance (ANOVA). The ANOVA results revealed that all factors studied had highly significant effects on total sugar liberated (P<0.01). The optimum conditions for PKC hydrolysis were 20% (w/v) PKC concentration, 5% (w/w) mannanase loading, hydrolysis pH 4.5, 45°C temperature and 72h hydrolysis time. Enzymatic experiments in optimum conditions revealed total fermentable sugars of 71.54±2.54g/L were produced including 67.47±2.51g/L mannose and 2.94±0.03g/L glucose. ABE fermentation of sugar hydrolysate by Clostridium saccharoperbutylacetonicum N1-4 resulted in 3.27±1.003g/L biobutanol.

INTRODUCTION: Sexting refers to the act of sending and receiving sexually explicit content in the form of in the form of texts, photos, or videos via the Internet and mobile phones. This behaviour is associated with many negative health consequences among young people. However, there is a lack of intervention studies to curb this behaviour. We have developed a new sexting prevention module and tested it using a randomised controlled field trial. This paper reported the phase one of the study i.e., the development of an animated sexting prevention module using the prototype willingness model (PWM) to reduce the intention and willingness to sext amongst diploma students in Malaysia.
MATERIALS AND METHOD: The initial phase involved a review of previous interventions, validation from field experts, and the process of developing video. Then the module pilot was tested among 30 diploma students from a public university. They were given access to the newly developed videos posted on a private YouTube channel and asked to evaluate the videos quantitatively and qualitatively by using the acceptability of the intervention module (AIM), intervention appropriateness measure (IAM) and feasibility of the intervention measure (FIM). The minimum and maximum scores of each measure were 12 and 24 respectively whereby a higher score indicated greater acceptability, appropriateness and feasibility.
RESULTS: The intervention consisted of five sections addressing the constructs of PWM, namely attitude, perceived norm, prototype perception, as well as intention and willingness of sexting. The contents were then converted into five videos with a total duration of 23 minutes. Based on the pilot test, the scores of AIM, IAM and FIM were not normally distributed and their median and the interquartile range values were 20 (4), 21 (4) and 22 (4) respectively. Most of the respondents gave favourable opinions on the intervention besides providing some input for improvement.
CONCLUSION: This animated sexting intervention module based on PWM to reduce the intention and willingness was novel. The module was acceptable, appropriate and feasible to be implemented among undergraduate students. Further evaluation of this intervention module can be performed to provide more comprehensive evidence of its effectiveness.

A cross-sectional study was carried out in University of Malaya Medical Centre, Kuala Lumpur. Blood samples from 100 HIV-infected patients and 203 Healthy Blood Donors (HBD) were collected and anti-Toxoplasma antibodies were detected by using conventional ELISA. The seroprevalence of toxoplasmosis in HIV/AIDS and Healthy Blood Donors were found to be 21% and 28.1% respectively. There was no significant association between the seroprevalence of toxoplasmosis and various possible risk factors i.e. contact with cat, consumption of undercooked meat and history of blood transfusion in both groups. No significant differences between Toxoplasma seroprevalence in HIV/AIDS and Healthy Blood Donors in association with presence of single or multiple risk factors were found. The mean CD4 count among HIV/AIDS patients in this study was 202.23 cell/cumm. There was no significant association between CD4 count and seropositivity for Toxoplasma antibodies in HIV/AIDS patients.
