METHODS: Between December 2016 and October of 2017, a total of 158 eligible individuals were classified as 50 healthy subjects and 108 diabetic patients who were subdivided into six groups according to the type of anti-diabetic treatments.
RESULTS: Overall, the results elucidated that hemoglobin concentration was markedly diminished, while red cell distribution width (RDW) value was significantly (P < 0.001) elevated in all diabetic groups as compared to control. Moreover, in all diabetic groups, malondialdehyde (MDA) concentration was elevated noticeably (P < 0.001), while reduced glutathione (GSH) revealed a lower concentration (P < 0.001) than that of control.
CONCLUSION: The present study exhibited the amelioration effect of metformin administration on oxidative stress and glycemic status which reflected on some RBCs indices. However, hemoglobin concentration showed a noticeable diminution in all metformin-treated groups in spite of the improvement in glycemic and oxidative stress status which indicated that the metformin-induced anemia is independently from diabetic complications.
METHODS: A convenience sampling method was used in a cross-sectional study of 290 undergraduate Health Sciences students in public universities. The Perceived Stress Scale (PSS-10) was used to measure the perception of stress, and the Multidimensional Scale of Perceived Social Support (MSPSS) was used to measure perceived social support from three sources, including family, friends and significant others.
RESULTS: A statistically significant correlation was found between the stress level and the total score of the MSPSS (r = -0.432), perceived social support from family (r = -0.429), significant others (r = -0.328), and friends (r = -0.219, P < 0.001). Over three-quarters (73.4%) of the students have a moderate stress level (mean = 21.17, SD = 5.75). The highest social support perceived was from a family (mean = 5.21, SD = 1.48).
CONCLUSION: The study suggested that social support from family is the strongest for students to go through the stress of tough times. It also highlighted the need for attention to stress management among undergraduate students for healthy well-being. Future studies that involve other academic fields of study and qualitative research would give useful information on perceived social support among students.
METHODS: General Electric (GE) Senographe DMR Plus mammography unit was used for MGD and MTF evaluation. The measured MGD was compared with the dose reference level (DRL), whereas the MTF was evaluated using ImageJ 1.46o software. A modified Mammography Accreditation Phantom RMI 156 was exposed using different target-filter combinations of molybdenum-molybdenum (Mo-Mo), molybdenum-rhodium (Mo-Rh) and rhodium-rhodium (Rh-Rh) at two different tube voltages, 26 kV and 32 kV with 50 mAs.
RESULTS: In the MGD evaluations, all target-filters gave an MGD value of < 1.5 mGy. The one-way ANOVA test showed a highly significant interaction between the MGD and the kilovoltage and target-filter material used (26 kV: F (2,12) = 49,234, P = 0.001;32 kV: F (2,12) = 89,972, P = 0.001). A Tukey post-hoc test revealed that the MGD for 26 kV and 32 kV was highly affected by the target-filter combinations. The test of homogeneity of variances indicates that the MGD varies significantly for 26 kV and 32 kV images (0.045 and 0.030 (P < 0.05), respectively). However, the one-way ANOVA for the MTF shows that no significant difference exists between the target-filter combinations used with 26 kV and 32 kV images either in parallel or perpendicular to the chest wall side F (2,189) = 0.26, P > 0.05).
CONCLUSION: Higher tube voltage and atomic number target-filter yield higher MGD values. However, the MTF is independent of the X-ray energy and the type of target-filter combinations used.
Methods: This cross-sectional study uses a pre-validated, self-administered questionnaire, which has been administered to 200 residents in Jitra, Kedah, Malaysia. Descriptive and inferential statistics have been used to analyse the data.
Results: Females formed 64.0% of the participants, with Malay being the dominant ethnic group (n = 167, 83.5%); 77.5% of the participants reported they were aware of the role of pharmacists in the healthcare system. However, 35.0% of the participants reported having never heard the term 'dispensing separation' in any mainstream media in Malaysia, whereas 73.5% of the participants reported that a pharmacist was more reliable than a physician in providing medicines once the diagnosis had been made and 77.5% of them acknowledged that pharmacists were experts in the field of medication. There was a significant association between the participant's awareness and the agreement on perceptions toward the implementation of the DS (P < 0.05).
Conclusion: Awareness of the implementation of DS among residents in Jitra is still low. However, there is strong evidence of public support and the benefits of DS in Malaysia.
METHODS: This two-arm cluster-randomised controlled trial was implemented between January 2018 and November 2018. Six schools were selected using stratified random sampling, whereby students were purposively selected and invited. The criteria of inclusion to the programme were secondary school students (aged 13 years old-17 years old) who smoked conventional cigarettes (CC) and electronic cigarettes (EC).
RESULTS: A total of 422 students from six schools participated in this study. Three schools were designated as intervention (n = 250) and the other three as control schools (n = 172). Formative evaluation of participants in the FSSCP using the logic model showed that participants were satisfied with the overall programme (91.5%), were motivated to stop smoking (90.4%) and were prevented from relapse (89.2%). The quit rate at a 3-month follow-up was 41.8%.
CONCLUSION: The logic model supported the development of the programme, with details on the processes, dissemination activities, identification of barriers, evaluation criteria and outcomes provided.
Methods: Patients diagnosed with BPH with severe LUTS who had undergone PAE were included. Their IPSS score was ≥ 20 despite medical therapy. PAE was performed via the unilateral femoral artery using various types of embolic material. Bilateral or unilateral embolisation of the prostate artery was considered a technical success. The severity of LUTS pre- and post-PAE were assessed using IPSS while prostate volume pre- and post-PAE were assessed by ultrasound and magnetic resonance imaging (MRI).
Results: Ninety percent of patients had technical success and one required transurethral resection of the prostate (TURP). The mean IPSS reduction at the final follow-up was 12.9 (P < 0.028). The mean reduction of prostate volume at the last follow-up by ultrasound was 114.99 mL (P < 0.028) and by MRI was 29.17 mL (P < 0.028).
Conclusion: PAE is safe and effective in reducing severe LUTS and prostate gland volume in BPH patients.
AIM: To compare the quality of CT brain images produced by a fixed CT scanner and a portable CT scanner (CereTom).
METHODS: This work was a single-centre retrospective study of CT brain images from 112 neurosurgical patients. Hounsfield units (HUs) of the images from CereTom were measured for air, water and bone. Three assessors independently evaluated the images from the fixed CT scanner and CereTom. Streak artefacts, visualisation of lesions and grey-white matter differentiation were evaluated at three different levels (centrum semiovale, basal ganglia and middle cerebellar peduncles). Each evaluation was scored 1 (poor), 2 (average) or 3 (good) and summed up to form an ordinal reading of 3 to 9.
RESULTS: HUs for air, water and bone from CereTom were within the recommended value by the American College of Radiology (ACR). Streak artefact evaluation scores for the fixed CT scanner was 8.54 versus 7.46 (Z = -5.67) for CereTom at the centrum semiovale, 8.38 (SD = 1.12) versus 7.32 (SD = 1.63) at the basal ganglia and 8.21 (SD = 1.30) versus 6.97 (SD = 2.77) at the middle cerebellar peduncles. Grey-white matter differentiation showed scores of 8.27 (SD = 1.04) versus 7.21 (SD = 1.41) at the centrum semiovale, 8.26 (SD = 1.07) versus 7.00 (SD = 1.47) at the basal ganglia and 8.38 (SD = 1.11) versus 6.74 (SD = 1.55) at the middle cerebellar peduncles. Visualisation of lesions showed scores of 8.86 versus 8.21 (Z = -4.24) at the centrum semiovale, 8.93 versus 8.18 (Z = -5.32) at the basal ganglia and 8.79 versus 8.06 (Z = -4.93) at the middle cerebellar peduncles. All results were significant with P-value < 0.01.
CONCLUSIONS: Results of the study showed a significant difference in image quality produced by the fixed CT scanner and CereTom, with the latter being more inferior than the former. However, HUs of the images produced by CereTom do fulfil the recommendation of the ACR.
Methods: We performed diffusion magnetic resonance imaging with probabilistic tractography on four Malay males to parcellate the hippocampus according to its relative connection probability to the six subdivisions of the PFC.
Results: Our findings revealed that each hippocampus showed putative connectivity to all the subdivisions of PFC, with the highest connectivity to the orbitofrontal cortex (OFC). Parcellation of the hippocampus according to its connection probability to the six PFC subdivisions showed variability in the pattern of the connection distribution and no clear distinction between the hippocampal subregions.
Conclusion: Hippocampus displayed highest connectivity to the OFC as compared to other PFC subdivisions. We did not find a unifying pattern of distribution based on the connectivity-based parcellation of the hippocampus.
