Methods: This is a prospective cohort study of 40 low birth weight newborns in our institutions. We randomly assigned the newborns to the group which received KMC and to the group which received conventional care. Maternal factors were recorded. We measured weight, length, and head circumferences of newborns daily for thirty days. Data was processed by SPSS x22.0. Results: A total of 40 newborns were recruited into the study. Weight parameters were significantly higher in the KMC group than in the conventional group except for the Z scores. Regarding maternal characteristics, only gestational age was found to influence the initial and the last head circumference (p=0.035). There were no differences in maternal age, parity, maternal education, mode of delivery, fetal sex, and initial Apgar score with any of the growth parameters.

Since angiogenesis has been found to be closely related to the invasiveness of breast cancer, angiogenic marker such as vascular endothelial growth factor (VEGF) may be a promising marker for this cancer. Objective: The aim of this study is to determine the association between the VEGF receptor (VEGFR) expression with human epidermal growth factor receptor-2 (HER-2)/ neu and estrogen receptor (ER) /progesterone receptor (PR) expression in an attempt to clarify the role of VEGFR as a potentially novel predictive and prognostic biomarker for breast cancer. Materials and Methods: This study examined 40 tissue biopsies taken from patients diagnosed with breast cancer in H. Adam Malik Hospital Medan, Indonesia. Samples were analyzed by immunohistochemistry to determine the histopathology, grading, lymphovascular invasion and expression of VEGFR, HER-2/neu and ER/PR. Association between dependent and independent variables was conducted using chi-square test and logistic regression. Results: The majority of the cases in this study were infiltrating ductal carcinoma (90%), in stage III (70%), and showed positive TIL (75%). VEGFR expression was found to be upregulated in 21 samples (52.5%). HER-2/neu was positive in 14 patients (35.0%) and ER/PR was positive in 22 patients (55%). The expression of VEGFR positively correlated with HER-2/neu expression (p= 0.002) and negatively correlated with ER/PR expression (p= 0.012). Conclusion: Overexpression of VEGFR is a potential valuable predictive and prognostic biomarker for breast cancer. Antagonising VEGFR may serve as the future target therapy for the disease.","PeriodicalId":39135,"journal":{"name":"Journal of the University of Malaya Medical Centre","volume":"9 8 1","pages":"26-30"},"PeriodicalIF":0.0,"publicationDate":"2016-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68652200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Publications on FH are mainly from western patients as there is little research on Asians, including Malaysians. The aim of this review is to provide an up-to- date information on Malaysian studies on FH genotyping and its relation to the phenotype of the affected patients. Method: A search was conducted for data from online databases on FH in Malaysia. Results: The mutation spectrum for FH among Malaysian patients was extremely broad. The gene variants were located mainly in the low-density lipoprotein receptor (LDLR) and apolipoprotein B-100 (APOB-100) genes rather than in the proprotein convertase subtilisin kexin type 9 (PCSK9) gene. The exon 9 and 14 were the hotspots in the LDLR gene. The most frequent mutation was p.Cys255Ser, at 12.5%, followed by p.Arg471Gly, at 11%, and the most common single nucleotide polymorphism (SNP) was c.1060+7 T>C at 11.7%. The LDLR gene variants were more common compared to the APOB-100 gene variants, while variants in the PCSK9 gene were very few. Phenotype-genotype associations were identified. Subjects with LDLR and APOB-100 genes mutations had a higher frequency of cardiovascular disease, a family history of hyperlipidaemia and tendon xanthoma and a higher low-density lipoprotein cholesterol (LDL-C) level than non-carriers. Conclusion: Research on Malaysian familial hypercholesterolaemic patients by individual groups is encouraging. However, more extensive molecular studies on FH on a national scale, with a screening of the disease-causing mutations together with a comprehensive genotype-phenotype association study, can lead to a better outcome for patients with the disease.","PeriodicalId":39135,"journal":{"name":"Journal of the University of Malaya Medical Centre","volume":"19 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2016-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68651847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared the efficacy of anew under-body forced-air warming blanket with that of a resistive heating blanket in preventing hypothermia.Methods:Sixty patients undergoing major posterior approach spinal surgery lasting for more than 2 hours were randomlyassigned to warming with a full under-body forced-air warming blanket or three segments of resistive heatingblankets, both set at 42°C. The ambient temperature was kept near 20°C. Nasopharyngeal, rectal and axillarytemperatures were measured at regular intervals.

It is one of the most common neurodegenerative diseases causing blindness. Pre-clinical studies have been carried out on animal models of glaucoma for stem cell therapy. We carried out a systematic review to determine whether stem cell therapy had the potential to treat glaucoma. Nine studies were selected based on the predetermined inclusion and exclusion criteria. Of these nine studies, eight focused on neuroprotection conferred by stem cells, and the remaining one on neuroregeneration. Results from these studies showed that there was a potential in stem cell based therapy in treating glaucoma, especially regarding neuroprotection via neurotrophic factors. The studies revealed that a brain-derived neurotrophic factor expressed by stem cells promoted the survival of retinal ganglion cells in murine glaucoma models. The transplanted cells survived without any side effects. While these studies proved that stem cells provided neuroprotection in glaucoma, improvement of vision could not be determined. Clinical studies would be required to determine whether the protection of RGC correlated with improvement in visual function. Furthermore, these murine studies could not be translated into clinical therapy due to the heterogeneity of the experimental methods and the use of different cell lines. In conclusion, the use of stem cells in the clinical therapy of glaucoma will be an important step in the future as it will transform present-day treatment with the hope of restoring sight to patients with glaucoma.","PeriodicalId":39135,"journal":{"name":"Journal of the University of Malaya Medical Centre","volume":"19 1","pages":"23-32"},"PeriodicalIF":0.0,"publicationDate":"2016-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68652177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

QoL was measured using standard SF-8 questions to capture its different dimensions. Results: Donors in the 1991–1998 donation cohort have low QoL, especially in the domains of physical and vitality, compared with the other two cohorts (1999–2005 and 2006–2012). The mean scores showed that donors who never went for any follow-up activities visits experience low QoL in most of the categories, particularly those related to physical activities, implying the importance of follow-up activities visits in influencing the donors’ QoL. Lower QoL was recorded for respondents that never received post-transplant treatment.
