Introduction: Flooding has become a major natural disaster in Malaysia in recent decades. There may be a gender difference in many aspects related to flood response and practice. This study aimed to examine the gender gap in knowledge, attitudes, and practice of flood preparedness in Malaysia. Method: This cross-sectional study was conducted among patients attending the primary care clinic at Universiti Sains Malaysia health campus, Kelantan. A validated questionnaire was used for data collection. Results: 328 subjects were recruited, 56.1% of them were females. The female respondents were younger than the males (36 vs. 41 years old). However, females have better knowledge, and practice on flood preparedness compared to male respondents. Among those, women were more aware of the local emergency plan than males (p=0.01). More female respondents kept their vaccination and personal medical records in a waterproof container or sealed plastic bag during past and future flood preparations (3-5 day supply of non-perishable food) than male respondents (p<0.05). In addition, with the practice of keeping a one-week supply of medication, and having their medical records in a waterproof container along with a first-aid kit (p=0.001). For future flood preparation, more women would filter the cloudy water through clean clothes for boiling (p=0.035). The determinants of good preparedness for future floods for female were older-age (p=0.001), blue-collar (p=0.043); whereas male were lower household income (p=0.014), being blue collar (0.014) and white collar (0.039) compared with student/retiree based on multivariate logistic regression. Conclusion: Our study reported that the determinants of good preparedness for future floods were older-age, blue-collar and having a lower-household income.

Introduction: This study aimed to determine the prevalence and factors associated with psychological distress following the COVID-19 pandemic among medical students at one of the public universities in Malaysia. Method: From August to October 2020, a web-based cross-sectional study was conducted among undergraduate medical students at a public university. DASS-21, Brief Resilience Scale and WHOQOL-Bref questionnaires were used in this study. Results: The prevalence of depression was 40.5%, anxiety 46.0% and stress 30.9%. Based on multivariate logistic regression, a higher quality of life score is associated with a lower likelihood of depression (AOR=0.583, p<0.001), anxiety (AOR=0.726, p<0.001), and stress, (AOR=0.702, p<0.001) respectively. Likewise, a higher resilience score is less likely to be associated with depression (AOR=0.880, p=0.002), anxiety (AOR=0.880, p=0.002), and stress (AOR=0.850, p<0.001). Older age (OR=0.700, p=0.020) was associated with less stress and being on campus (OR=3.436, p=0.021) was at risk of stress during the COVID-19 pandemic. Conclusion: Our results suggest that medical students with higher quality of life and resilience scores had less depression, anxiety and stress. Older age was associated with less stress, and during the COVID-19 pandemic, being on campus was at risk of stress. Various stakeholders need to keep these findings in mind and identify those who are at risk for developing depression, anxiety, and stress in order to take further action to improve their quality of life and resilience

Introduction: Diabetic Peripheral Neuropathy (DPN), the most common complication of Diabetes Mellitus (DM), is often under-diagnosed and inadequately treated. This study identified the proportion of undiagnosed DPN and its associated risk factors among patients with established type 2 DM (T2DM) in community health clinics in the Gombak district. Methods: A cross-sectional study was conducted in 2 community health clinics within the Gombak district between September and December 2017. Adults with T2DM were selected via systematic random sampling and screened using the Neuropathy Symptoms Score (NSS). Clinical records of participants’ foot examinations were reviewed to identify positive findings of DPN and compared with the NSS. Results: The study’s sample comprised 425 patients. Most had co-morbidities, including hypertension, dyslipidaemia and pre-existing DM-related complications. About two-thirds of them performed no daily foot inspection and had no proper footwear. The proportion of patients with positive NSS was 49.4%. However, only 0.2% were diagnosed with positive DPN in their clinical foot examination record. Conclusion Although a positive NSS was identified in 1 out of 2 patients with established DM, only 0.2% of patients had DPN on their examination records. Most patients had never done daily foot inspections and lacked proper footwear. A positive NSS was associated with uncontrolled diabetes and lower BMI. Proper screening and examination for patients, especially those with uncontrolled diabetes and low BMI, is crucial in identifying DPN to ensure that these diabetic patients receive better preventative care, especially proper foot care and strict diabetic control, to prevent DPN-related complications.

BACKGROUND: This study was performed to assess serial cytokine changes and their clinical impact in children with cerebral palsy (CP) who received granulocyte-colony stimulating factor (G-CSF) followed by infusion of autologous mobilized peripheral blood mononuclear cells (mPBMCs). METHODS: Peripheral blood (PB) samples were collected from 16 CP children at enrollment, and 1 month and 7 months after G-CSF infusion as well as at the end of the study. Cytokine levels were measured by enzyme-linked immunosorbent assays with plasma samples. RESULTS: There were no significant differences in cytokine levels between the mPBMC and placebo groups over 6 months. However, when clinical responders and non-responders were compared, interleukin (IL)-6 (P = 0.050) as well as G-CSF (P = 0.010) were higher in the responders than the non-responders at 1 month, while brain-derived neurotrophic factor (BDNF) (P = 0.030) and insulin-like growth factor (IGF)-1 (P = 0.001) were lower. In addition, BDNF was higher at baseline in the responders than the non-responders (P = 0.030). CONCLUSION: The changes of G-CSF itself, as well as G-CSF-induced cytokines such as IL-6, may be associated with the clinical improvement of neurologic functions. The G-CSF-induced changes of IL-6, BDNF and IGF-1, and BDNF levels before treatment, could be used as prognostic factors in G-CSF trials in CP children.

The aim of this study was to assess the differences in the mortality and in-hospital outcomes of preterm infants with < 28 weeks of gestation who received ibuprofen treatment according to the presence of clinical symptoms (any of oliguria, hypotension, or moderate to severe respiratory difficulty) attributable to hemodynamically-significant patent ductus arteriosus (hsPDA) at the time of first ibuprofen treatment. In total, 91 infants born from April 2010 to March 2015 were included. Fourteen infants (15.4%) received ibuprofen treatment when there were clinical symptoms due to hsPDA (clinical symptoms group). In clinical symptoms group, infants were younger (25 [23–27] vs. 26 [23–27] weeks; P = 0.012) and lighter (655 [500–930] vs. 880 [370–1,780] grams; P < 0.001). Also, the clinical risk index for babies (CRIB)-II scores were higher and more infants received invasive ventilator care ≤ 2 postnatal days. More infants received multiple courses of ibuprofen in clinical symptoms group. Although the frequency of secondary patent ductus arteriosus (PDA) ligation and the incidence of bronchopulmonary dysplasia (BPD) was higher in the clinical symptoms group in the univariate analysis, after multivariate logistic regression analysis adjusting for the CRIB-II score, birthweight, birth year, and the invasive ventilator care ≤ 2 postnatal days, there were no significant differences in mortality, frequency of secondary ligation and in-hospital outcomes including necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), BPD or death. Our data suggest that we can hold off on PDA treatment until the clinical symptoms become prominent.

OBJECTIVE: To investigate the effect of intravenous infusion of peripheral blood mononuclear cells (mPBMC) mobilized by granulocyte-colony stimulating factor (G-CSF) on upper extremity function in children with cerebral palsy (CP). METHODS: Fifty-seven children with CP were enrolled. Ten patients were excluded due to follow-up loss. In total, 47 patients (30 males and 17 females) were analyzed. All patients' parents provided signed consent before the start of the study. After administration of G-CSF for 5 days, mPBMC was collected and cryopreserved. Patients were randomized into two groups 1 month later. Twenty-two patients were administered mPBMC and 25 patients received normal saline as placebo. Six months later, the two groups were switched, and administered mPBMC and placebo, respectively. Quality of Upper Extremity Skills Test (QUEST) and the Manual Ability Classification System (MACS) were used to evaluate upper motor function. RESULTS: All subdomain and total scores of QUEST were significantly improved after mPBMC and placebo infusion, without significant differences between mPBMC and placebo groups. A month after G-CSF, all subdomain and total scores of QUEST were improved. The level of MACS remained unchanged in both mPBMC and placebo groups. CONCLUSION: In this study, intravenously infused mPBMC showed no significant effect on upper extremity function in children with CP, as compared to placebo. The effect of mPBMC was likely masked by the effect of G-CSF, which was used in both groups and/or G-CSF itself might have other neurotrophic potentials in children with CP.

Pilocarpine-induced rat epilepsy model is an established animal model that mimics medial temporal lobe epilepsy in humans. The purpose of this study was to investigate neuroimaging abnormalities in various stages of epileptogenesis and to correlate them with seizure severity in pilocarpine-induced rat epilepsy model. Fifty male Sprague-Dawley rats were subject to continuous video and electroencephalographic monitoring after inducing status epilepticus (SE) and seizure severity was estimated by frequency and total durations of class 3 to 5 spontaneous recurrent seizures (SRS) by modified Racine's classification. The 7.0 Tesla magnetic resonance imaging (MRI) with high resolution flurodeoxyglucose positron emission tomography (FDG-PET) was performed at 3 hours, 1, 3, 7 days and 4 weeks after the initial insult. The initial SRS was observed 9.7±1.3 days after the pilocarpine injection. MRI revealed an abnormal T2 signal change with swelling in both hippocampi and amygdala in acute (day 1 after injection) and latent phases (days 3 and 7), in association with PET hypometabolism in these areas. Interestingly, the mean frequency of class 3 to 5 SRS was positively correlated with abnormal T2 signals in hippocampal area at 3 days. SRS duration became longer with more decreased glucose metabolism in both hippocampi and amygdala at 7 days after pilocarpine injection. This study indicates that development and severity of SRS at chronic phase could be closely related with structural and functional changes in hippocampus during the latent period, a pre-epileptic stage.

BACKGROUND: We compared the yields of mobilized PBSCs from single day of normal volume leukapheresis (NVL) in children and adults, and factors affecting the yields, to understand differences in mobilization efficiency between adults and small children with healthy marrows.METHODS: This study involved 18 adult volunteer donors and 47 small children weighing less than 20 kg who participated in a clinical trial of cell therapy in children with cerebral palsy. Donor factors analyzed to identify predictors of the yield of apheresis included age, gender, weight and complete blood cell count (CBC) with differential counts as well as equipment parameters.RESULTS: The yields of total nucleated cells (TNCs) and CD34⁺cells in the apheresis products of the children were significantly lower than in those from healthy adults. However, the efficiency of recovery of PBSCs (total CD34⁺ cell counts/TNCs) was significantly higher in small children (0.48±0.30%) than in adults (0.10±0.05%) (P < 0.05). Multivariable analysis of adult donor factors showed that the processed volume and flow rate of apheresis were significantly associated with the yield of TNCs (P < 0.05, for both), but not of CD34⁺cells. However, in multivariable analysis of child donor factors, body weight and circulating WBC count on the day of apheresis were significantly associated with the yield of TNCs (P < 0.05, for both) and of CD34⁺cells (P < 0.05, for both).CONCLUSION: The predictors of PBSC yields from a single day of NVL in adults and small children are different. Also mobilization is more effective in small children than in adults.

BACKGROUND: Flow cytometric analysis is the standard method for enumerating CD34+ stem cells in hematopoietic stem cell transplantation. However, it has some limitations such as expensive instrumentation, high reagent costs, and discrepancies between technicians and laboratories. We compared counts of total nucleated cells (TNCs) and CD34+ cells counts obtained from a flow cytometer with a newly-developed image-based microscopic cell counter (ADAM II) to evaluate the possibility of clinical application of the ADAM II.METHODS: We used 18 samples of circulating peripheral blood (PB) and waste tube fractions of peripheral blood stem cells (PBSCs) harvested by apheresis after G-CSF mobilization from adult volunteer donors. We assessed the reproducibility and linearity of the new procedure and compared the numbers of TNCs and viable CD34+ cells determined with the ADAM II and two different flow cytometers (FACSCalibur, FACSCanto II).RESULTS: Numbers of viable CD34+ cells determined with the ADAM II were accurate over the expected range; the intra-assay coefficient of variation was ≤19.8%. Linearity was also satisfactory (R²=0.99). TNC counts obtained with the ADAM II were highly correlated with those obtained with the FACSCalibur (R²>0.9841, P<0.0001) and FACSCanto II (R²>0.9620, P<0.0001), as were the numbers of viable CD34+ cells obtained with the ADAM II and the FACSCalibur and FACSCanto II (R²>0.9911, P<0.0001 and R²>0.9791, P<0.0001), respectively.CONCLUSION: The newly developed image-based microscopic cell counter (ADAM II) appears to be suitable for enumerating TNCs and viable CD34+ cells.

OBJECTIVE: In this study we utilized the Surveillance, Epidemiology and End-Results (SEER) registry to identify risk factors for lymphatic spread and determine the incidence of pelvic and para-aortic lymph node metastases in patients with uterine papillary serous carcinoma (UPSC) and uterine clear cell carcinoma (UCCC) who underwent complete surgical staging and lymph node dissection. METHODS: Nine hundred seventy-two eligible patients diagnosed between 1998 to 2009 with International Federation of Gynecology and Obstetrics (FIGO) 1988 stage IA-IVA UPSC (n=685) or UCCC (n=287) were identified for analysis. Binomial logistic regression was used to determine risk factors for lymph node metastasis, with the incidence of pelvic and para-aortic lymph node metastases reported for each FIGO primary tumor stage. The Cox proportional hazards regression model was used to determine factors associated with overall survival. RESULTS: FIGO primary tumor stage was the only independent risk factor for lymph node metastasis (p<0.01). The incidence of pelvis-only and para-aortic lymph node involvement according to the FIGO primary tumor stage were as follows: IA (2.3%/3.8%), IB (7.5%/5.2%), IC (22.5%/16.9%), IIA (20.8%/13.2%), IIB (25.7%/14.9%), and III/IV (25.7%/24.3%). Prognostic factors for overall survival included lymph node involvement (hazard ratio [HR], 1.42; 95% confidence interval [CI], 1.09 to 1.85; p<0.01), patient age >60 years (HR, 1.70; 95% CI, 1.21 to 2.41; p<0.01), and advanced FIGO primary tumor stage (p<0.01). Tumor grade, histologic subtype, and patient race did not predict for either lymph node metastasis or overall survival. CONCLUSION: There is a high incidence of both pelvic and para-aortic lymph node metastases for FIGO stages IC and above uterine papillary serous and clear cell carcinomas, suggesting a potential role for lymph node-directed therapy for these patients.
