Integrated Life Skills Training and Executive Function Strategies in Children With Autism Spectrum Disorder in Qatar: A Pilot Study of a Randomized Controlled Trial.

Background and aim Executive function (EF) impairment is common in children with autism spectrum disorder (ASD). EF strategies are considered effective in improving the therapeutic outcomes of children with ASD. This study primarily aimed to explore whether integrating EF strategies combined with regular occupational therapy intervention is more effective in improving daily life skills (DLS) and sensory integration/processing (SI/SP) skills than regular occupational therapy alone in children with ASD and secondarily aims to assess treatment outcomes on improving visual motor integration (VMI) skills. Methods A total of 17 participants (13 males, mean age 4.29 years, standard deviation 0.66) completed the study. Following the baseline assessments, the participants were randomly assigned to the treatment group (45-minute once-weekly individual occupational therapy plus EF strategies) or control group (45-minute once-weekly individual therapy sessions alone). All participants received one intervention per week for 14 weeks. All children were systematically evaluated using a pediatric functional independent measure (WeeFIM) and the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) to assess DLS, the Short Sensory Profile 2 (SSP2) to assess SP/SI, and the Beery VMI test (Beery VMI) to assess VMI. Assessments were conducted at baseline, seven weeks, and 14 weeks of treatment.  Results The analysis of the results between the treatment and control groups revealed that the treatment group had greater gains and significant differences in the mean values of both the WeeFIM and SSP2. In addition, notable distinctions were observed in the VB-MAPP transition subscale; although these differences did not reach statistical significance, they were clinically significant. Minimal differences were noted in the VMI between the two groups. Nevertheless, both groups showed statistically significant improvements across all outcome measures. Conclusions Our study provides preliminary evidence of the efficacy of EF strategies combined with regular occupational therapy for DLS, SP/SI, and VMI in children with ASD. The differences between the groups support further evaluation of the effectiveness of EF strategies for the next stage of a larger randomized clinical trial.

GFAT1: A Potential Prognostic Biomarker in Colorectal Cancer

@#Introduction: There is an increasing demand for additional techniques to diagnose and treat cancer including CRC or colorectal cancer effectively. Utilizing antibodies as biomarker could contribute to accurate diagnosis of cancer due to its high specificity and sensitivity. One of the etiologies of CRC progression was proposed as the alterations of hexosamine biosynthetic pathway which could subsequently influence the rate-limiting enzyme, glutamine-fructose-6-phosphate aminotransferase (GFAT1). These increased enzymatic activities resulted in an elevation of glucose uptake that provides nutrients facilitating the progression of cancer cells. Therefore, we attempted to determine the potential of GFAT1 as the biomarker for CRC by correlating its expression with clinicopathological features of the patients. Methods: A total of 132 10% formalin-fixed paraffin embedded tissue were retrieved. Immunohistochemistry (IHC) was performed on the tissue sections and digital images were subsequently acquired. All the images were automatedly analyzed using IHC Profiler. GFAT1 immunoreactivity in colorectal tissues was calculated using an adapted H-score formula. Clinicopathological features of the patients were statistically correlated with the status of GFAT1. Results: Colorectal adenocarcinoma tissues had the significantly highest GFAT1 H-scores with the mean of 103.18 compared to adenoma and non-tumor tissues. There have been no significant associations between clinicopathological characteristics of the patients and the status of GFAT1 except for tumor size. Conclusion: Immunoreactivity of GFAT1 was significantly different between non-tumorous tissues and adenocarcinoma as well as between adenoma and adenocarcinoma tissues. GFAT1 could serve as one of the prognostic biomarkers or useful targets.

Impacts of Microprocessor-Controlled Versus Non-microprocessor-Controlled Prosthetic Knee Joints Among Transfemoral Amputees on Functional Outcomes: A Comparative Study.

INTRODUCTION: Selecting a prosthetic knee mechanism is an important part of transfemoral (TF) amputee rehabilitation. Prosthetic knee joint selection depends on the users' gait and their energy consumption. This study compares the feedback of transfemoral prosthesis users based on the prosthetic knee design self-reporting responses using the Prosthetic Evaluation Questionnaire (PEQ) outcome measure. OBJECTIVE: This study aims to assess the impact of using a microprocessor-controlled prosthetic knee (MCPK) compared with a non-microprocessor-controlled prosthetic knee (NMCPK); feedback on the amputee usage can improve the clinical decision for proper prosthetic knee joint selection. METHODS: This is a cross-sectional study with a total of 76 adult unilateral transfemoral amputees classified into two groups. The participants in the first group (38) used the MCPK (Genium, Otto Bock, Minneapolis, MN, USA), and the participants in the second group (38) used the NMCPK (hydraulic and total knee joints). Enrolment was based on a sequence of appointments where all participants answered the PEQ, with different subscale questions including utility (UT), sounds (SO), appearance (AP), residual limb health (RL), frustration (FR), perceived response (PR), social burden (SB), ambulation (AM), and quality of life (QoL). PEQ was filled out during the follow-up appointments at the prosthetic clinic through a visual analog scale (VAS). All data entered into a database were analyzed. RESULT: The MCPK participants have significantly improved utility, appearance, ambulation, and total PEQ score, the same results as the male participants. Middle-adulthood (25-40 years) MCPK participants have a significant p-value in the score of utility, frustration, ambulation, and total PEQ score compared to early-adulthood (18-24 years) and late-adulthood (41-60 years) participants. Also, there was a significant improvement in the p-value in ambulation scores in participants using MCPK with amputations caused by diseases compared to amputations caused by trauma and congenital cause. CONCLUSION: Transfemoral amputee prosthesis utility, natural gait, and ambulation improved when using MCPK compared to when using NMCPK during prosthetic rehabilitation.

Predictors of Coronary Heart Disease (CHD) among Malaysian Adults: Findings from MyDiet-CHD Study

@#Introduction: This study aimed to determine the risk factors of CHD among the Malaysian adult population. Methods: Using a cross- sectional observational study design, this study involved 365 adult patients aged between 30-64 years, attending clinics from eight government hospitals and four health clinics in Terengganu, Pahang, Selangor, Putrajaya, Penang, Kedah, Johor and Sabah from February 2018 until September 2020. Sociodemographic characteristics, clinical and dietary data, physical activity and stress level were recorded using a structured questionnaire. Multiple logistic regression was used to analyse CHD risk factors. Results: The overall response rate was 99.2%. The adjusted odds ratio of CHD was greater for age (AOR; [%95 CI]) (1.043;[ 1.009,1.078]); waist circumference (1.033;[1.009, 1.057]); total fat intake (1.035;[1.021, 1.050]); full cream dairy products intake (1.004;[1.001, 1.008]); smokers vs non-smokers (4.691;[2.399, 9.176]); individual with family history of CHD vs without family history (2.705;[ 1.496, 4.891]); married vs single (0.434;[ 0.217,0.867]); and lower for HDL cholesterol (0.185;[0.052, 0.662]); Chinese vs Malays (10.619;[ 2.255, 49.995]); and third lowest income (0.197;[ 0.073, 0.532]) and forth lowest income (0.167;[ 0.056, 0.499]) vs lowest income. Conclusion: Age, race, income, smoking and marital status, family history of CHD, waist circumference, HDL cholesterol, total fat intake, full cream dairy products intake were significantly associated with CHD among this population. This finding is particularly important to the primary health carers to identify at-risk CHD individuals thus appropriate intervention could be provided.

Comparison of Cox proportional hazards model, Cox proportional hazards with time-varying coefficients model, and lognormal accelerated failure time model: Application in time to event analysis of melioidosis patients

Objective: To compare the prognostic factors of mortality among melioidosis patients between lognormal accelerated failure time (AFT), Cox proportional hazards (PH), and Cox PH with timevarying coefficient (TVC) models. Methods: A retrospective study was conducted from 2014 to 2019 among 453 patients who were admitted to Hospital Sultanah Bahiyah, Kedah and Hospital Tuanku Fauziah, Perlis in Northern Malaysia due to confirmed-cultured melioidosis. The prognostic factors of mortality from melioidosis were obtained from AFT survival analysis, and Cox s models and the findings were compared by using the goodness of fit methods. The analyses were done by using Stata SE version 14.0. Results: A total of 242 patients (53.4%) survived. In this study, the median survival time of melioidosis patients was 30.0 days (95% CI 0.0-60.9). Six significant prognostic factors were identified in the Cox PH model and Cox PH-TVC model. In AFT survival analysis, a total of seven significant prognostic factors were identified. The results were found to be only a slight difference between the identified prognostic factors among the models. AFT survival showed better results compared to Cox's models, with the lowest Akaike information criteria and best fitted Cox-snell residuals. Conclusions: AFT survival analysis provides more reliable results and can be used as an alternative statistical analysis for determining the prognostic factors of mortality in melioidosis patients in certain situations.

Evidence of new intragenic HBB haplotypes model for the prediction of beta-thalassemia in the Malaysian population.

This study sought to determine the potential role of HBB haplotypes to predict beta-thalassemia in the Malaysian population. A total of 543 archived samples were selected for this study. Five tagging SNPs in the beta-globin gene (HBB; NG_000007.3) were analyzed for SNP-based and haplotype association using SHEsis online software. Single-SNP-based association analysis showed three SNPs have a statistically significant association with beta-thalassemia. When Bonferroni correction was applied, four SNPs were found statistically significant with beta-thalassemia; IVS2-74T>G (padj = 0.047), IVS2-16G>C (padj = 0.017), IVS2-666C>T (padj = 0.017) and 3'UTR + 314G>A (padj = 0.002). However, 3'UTR + 233G>C did not yield a significant association with padj value = 0.076. Further investigation using combined five SNPs for haplotype association analysis revealed three susceptible haplotypes with significant p values of which, haplotypes 1-2-2-1-1 (p = 6.49 × 10-7, OR = 10.371 [3.345-32.148]), 1-2-1-1-1 (p = 0.009, OR = 1.423 [1.095-1.850] and 1-1-1-1-1 (p = 1.39 × 10-4, OR = 10.221 [2.345-44.555]). Three haplotypes showed protective effect with significant p value of which, 2-2-1-1-1 (p = 0.006, OR = 0.668 [0.500-0.893]), 1-1-2-2-1 (p = 0.013, OR = 0.357 [0.153-0.830]) and 1-1-2-1-1 (p = 0.033, OR = 0.745 [0.567-0.977]). This study has identified the potential use of intragenic polymorphic markers in the HBB gene, which were significantly associated with beta-thalassemia. Combining these five SNPs defined a new haplotype model for beta-thalassemia and further evaluation for predicting severity in beta-thalassemia.

Predictors of in-hospital mortality by logistic regression analysis among melioidosis patients in Northern Malaysia: A retrospective study

Objective: To identify the predictors of mortality among in-hospital melioidosis patients. Methods: A total of 453 patients in Hospital Sultanah Bahiyah, Kedah, and Hospital Tuanku Fauziah, Perlis with culture-confirmed melioidosis were retrospectively included in the study. Advanced multiple logistic regression was used to obtain the final model of predictors of mortality from melioidosis. The analysis was performed using STATA/SE 14.0. Results: A total of 50.11% (227/453) of the patients died at the hospital, and a majority (86.75%, 393/453) of cases were bacteremic. The logistic regression estimated that the bacteremic type of melioidosis, low platelet count, abnormal white blood cell counts, and increased urea value were predictors of mortality. The results showed that bacteremic melioidosis increased the risk of death by 4.39 times (OR 4.39, 95% CI 1.83-10.55, P=0.001) compared to non-bacteremic melioidosis. Based on laboratory test, the adjusted ORs from the final model showed that all three blood investigations were included as the associated factors of mortality for the disease [high white blood cell (>10×109/L): OR 2.43, 95% CI 1.41-4.17, P7 800 μmol/L): OR 5.53, 95% CI 2.50-12.30, P<0.001; and low level of urea (<2 500 μmol/L): OR 3.52, 95% CI 1.71-7.23, P=0.001). Conclusions: Routine blood investigations during a hospital admission can early identify predictors of mortality in melioidosis patients.
