Fulltext Gaming Preferences and Personality among School Students

Rathakrishnan B, Bikar Singh SS, Yahaya A

Children (Basel), 2023 Feb 22;10(3).
PMID: 36979985 DOI: 10.3390/children10030428

Gaming has vastly developed into numerous genres; nonetheless, most studies in the literature emphasize the violent genre only. Therefore, this study was conducted to investigate the relationship between personality and gaming preferences among school students. This study also aims to investigate the difference in the time spent on gaming based on gender. The third objective involves examining the differences in frequency in playing a video game based on age. The sample group comprised 420 school students aged between 12 and 17 years old, including hardcore and casual gamers. The online survey was conducted using Google Forms, and the participants were requested to answer the demographic questionnaire, Big Five Inventory, and Gaming Preferences Questionnaire. The obtained data were analyzed using SPSS 26.0 software for general descriptive statistics. The results show that there was a significant relationship between gaming preferences role-playing game (RPG), combat, online, and music genres) and personality (extraversion, agreeableness, conscientious, neuroticism, and openness). The results also indicate a difference between gender and the number of hours spent on gaming, but no such difference existed between age and the frequency of playing games. From the psychological perspective, gaming preference is related to their personality and influences the behavior of children and overall health in daily life.

PMID: 34373248 DOI: 10.1136/bcr-2021-242276

Sarcomas are a group of rare malignant tumours of the connective tissues. They can occur in almost any location, but more frequently in the extremities. The occurrence of sarcomas in the head and neck region is less than 1%. We are presenting a case report of a very large cranial sarcoma. Gross total tumour excision was done with pedicle skin graft and titanium mesh cranioplasty. The excised tumour weighed approximately 1.1 kg. Histopathological examination showed primitive intermediate-sized tumour cells arranged in sheets, nests and cords with focal palisading. Postoperative MRI done 2 weeks post surgery showed no evidence of residual tumour.
Fulltext BDNF and DARPP-32 genes are not risk factors for schizophrenia in the Malay population

Loh HC, Tang PY, Tee SF, Chow TJ, Cheah YC, Singh SS

Genet. Mol. Res., 2012;11(1):725-30.
PMID: 22576830 DOI: 10.4238/2012.March.22.2

A number of studies have pointed to the association of BDNF (brain-derived neurotrophic factor) and DARPP-32 (dopamine- and cAMP-regulated phosphoprotein, 32 kDa) with schizophrenia. The purpose of this study was to determine whether these two genes are involved in the pathogenesis of schizophrenia in the Malay population. Two single nucleotide polymorphisms Val66Met of BDNF, -2036C>G and g.1238delG of DARPP-32 were genotyped in the Malay population in 200 patients with schizophrenia and 256 healthy controls. Analysis of allele and genotype frequencies in these two groups revealed no significant association of BDNF or DARPP-32 polymorphisms with schizophrenia in Malays. This is the first such association study in the Malay population.
Fulltext Smartphone Addiction and Sleep Quality on Academic Performance of University Students: An Exploratory Research

Rathakrishnan B, Bikar Singh SS, Kamaluddin MR, Yahaya A, Mohd Nasir MA, Ibrahim F, et al.

Int J Environ Res Public Health, 2021 08 05;18(16).
PMID: 34444042 DOI: 10.3390/ijerph18168291

This study was conducted to examine the relationship between smartphone addiction, sleep quality, and academic performance. The study presented quantitative research on 323 students in a public university in Sabah to explore the relationship between smartphone addiction, sleep quality, and academic performance. A simple random sampling was used in the study. The Smartphone Addiction Scale Short Version (SAS-SV) and the Pittsburgh Sleep Quality Index (PSQI) were used in this study. SPSS was used as a tool of analysis for descriptive and inferential analysis. Pearson correlation was involved to test the hypothesis of the study. The result indicated that the greater the smartphone addiction, the lower the academic performance of university students. The finding also proved that students with poor sleep quality might exhibit low academic performance. Smartphone addiction was found to be associated with sleep quality where overusing smartphones was related to poor sleep quality in university students. On this basis, the problem of smartphone addiction and sleep quality should be tackled in order to improve the academic performance of university students and their overall health.
Fulltext The impact of endometrial thickness (EMT) on the day of human chorionic gonadotropin (hCG) administration on pregnancy outcomes: a 5-year retrospective cohort analysis in Malaysia

Chan JM, Sukumar AI, Ramalingam M, Ranbir Singh SS, Abdullah MF

Fertil Res Pract, 2018;4:5.
PMID: 30116547 DOI: 10.1186/s40738-018-0050-8

Background: Chances of pregnancy in relation to endometrial thickness (EMT) remain elusive albeit some literatures suggest poorer pregnancy outcomes below the threshold of 6-7 mm, notwithstanding others perceive detrimental effect at thicker EMT. We aim to examine the implication of EMT on pregnancy outcomes using a cut-off of 8 mm and further explore for any effect of 'thick' EMT in our patient population.
Methods: This was a retrospective cohort study performed for 162 women to assess the associations between EMT on the human chorionic ganadotropin (hCG) trigger day and pregnancy outcomes in infertile patients undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) and autologous fresh embryo transfer (ET) in controlled ovarian stimulation (COS) cycles under an assisted reproductive technology (ART) shared-care programme between public and private institutions from January 2012 through December 2016.The associations between pregnancy outcomes [Total Pregnancy Rate (TPR), Biochemical Pregnancy Rate (BPR), Clinical Pregnancy Rate (CPR), Ongoing Pregnancy Rate (OPR)/ Live Birth Delivery Rate (LBDR), Miscarriage Rate (MR) and Implantation Rate (IR)] and EMT ( 0.05). All pregnancy outcomes were comparable for ≥14 mm and ≥ 8 to

Leptospirosis is an emerging zoonotic disease endemic in tropical regions. Aiming at assessing the potential infection risks via recreational exposure, the molecular prevalence of pathogenic Leptospira in 14 amenity forests in five selected districts of the state of Perak was determined. Water and soil samples along streams and waterfalls were subjected to culture of leptospires and the pathogenic Leptospira spp. was detected by lipL32-based polymerase chain reaction (PCR). Twenty out of 154 samples (13%) that tested positive for leptospires were mostly soils and still water recorded with tolerable temperatures (22.2- 26.5°C) and pHs (5.73-6.70). The localised prevalence was highly varied among eight positive forests (6.7-41.7%), particularly higher in Kampar and Kinta districts which are the more populated urban areas. The importance of public health surveillance should not be underrated given the high prevalence of Leptospira spp. in forests in close proximity to indigenous settlements, even where the places are clean. Overall, this study discovered a wide distribution of pathogenic Leptospira spp. in recreational areas.
An exposed Cardiovascular Implantable Electronic Device (CIED) complicated with infection: A case report of unconventional experience with 'Sealed CIED'

Mohd Said MR, Gian Singh SS, Chea CY, Mohd Firdaus MAB, Narasamuloo KR, Krishinan S

PMID: 35087011

The rate of infected Cardiovascular Implantable Electronic Device is alarming and causes substantial socio-economic burden. A common approach involves immediate extraction of the infected device. Here, we report an unorthodox approach to this problem by 'sealing' the generator inside a sterile container as a temporary permanent pacemaker while waiting for implantation of another device. We report a 66 years old emaciated lady with underlying Sick Sinus Syndrome, who had an implanted single chamber pacemaker and presented with partial protrusion of her device. She underwent sub-pectoral implantation of the new device but subsequently re-presented with pocket site infection after a month. A decision was made to extract the infected generator from the sub-pectoral pocket and it was sealed inside a sterile container as 'bridging therapy' while awaiting arrival of a leadless pacemaker for implantation together with total extraction of the old infected device. Our clinical vignette demonstrated the difficulties we encountered and influenced on our decision for this unconventional approach despite limited supporting evidence.
Fulltext An Extended Thickness-Dependent Moisture Absorption Model for Unidirectional Carbon/Epoxy Composites

Moisture absorption tests for materials that exhibit non-Fickian behavior generally require a relatively long period to reach saturation. Therefore, it would be beneficial to establish a relationship between the moisture content and the thickness to minimize the experimental time and cost. This research characterizes the moisture absorption behavior of AS4/8552 carbon/epoxy composites. Specimens were prepared at 4, 8, and 16 plies and immersed in distilled water at 60 °C. The relationship between the non-Fickian parameters (Fickian to non-Fickian maximum moisture content ratio ϕ, non-Fickian diffusivity per square thickness α, and non-Fickian initiation time to) and thickness was characterized using a thickness-dependent model. A comparison with other materials revealed that all three non-Fickian parameters are able to be fitted using a power law. Nevertheless, the upper boundary for the applicability of this model was not determined in this study. The Weibull distribution plots indicate that the probability of non-Fickian moisture absorption is influenced by ϕ and α at approximately 62% within a normalized thickness range of 2-3. In regards to to, it is 82% at a normalized thickness of 6. Therefore, the Weibull distribution is proposed for the assessment of non-Fickian moisture absorption based on the material's thickness.
