Type 2 diabetes mellitus (T2DM) is linked with a risk of dementia and decline in neurocognitive function. The current observational case-control study was conducted to evaluate the effect of fasting during Ramadan on cognitive functions and fatigue severity in T2DM patients using the Cambridge Neuropsychological Test Automated Battery (CANTAB). Methods: This research was conducted at King Saud University Medical city, on 82 subjects including 43 control and 39 T2DM patients of both genders. The standardized Fatigue Severity Scale (FSS) and tests from CANTAB, including the Motor Screening Task (MOT), Spatial Span (SSP) and Intra-Extra Dimensional Set Shift (IED) were recorded during 3 rd week and 2-3 weeks after Ramadan under controlled environmental conditions. Neurocognitive functions were recorded through CANTAB. Results: IED errors (24.43 vs 50.73, p ¼ 0.007), MOT mean and median latency (1466.32 vs 1120.27, p ¼ 0.002) were significantly higher in T2DM than controls. IED stages completed (7.43 vs 8.69, p ¼ 0.003) and SSP Span length were significantly lower in T2DM than controls (4.13 vs 4.82, p ¼ 0.059). The significant differences between T2DM patients and controls persisted in the post. T2DM patients made more errors and completed less IED stages than did the controls, indicating that a worsened flexibility of attention relative to controls. Moreover, T2DM patients exhibited longer latencies in MOT, indicating poor motor performance. A comparison of performances by T2DM patients on FSS and CANTAB during and after Ramadan showed that fasting substantially increased fatigue scales, motor performance, and working-memory capacity. Conclusions: Patients with T2DM have impaired cognitive functions including poor motor performance, low flexibility of attention, and poor working memory capacity compared to healthy control subjects during and also in post Ramadan period. However, there is no clear statistical evidence that the cognitive functions (except for SSP SL scores) and fatigue severity of T2DM subjects differ between Ramadan and after Ramadan in both T2DM and controls.
Background and Objective: Worldwide chest trauma is considered one of the leading causes of morbidity and mortality. There is a lack of sufficient information on the etiology, pattern, and management of these injuries in Saudi Arabia. Therefore, the current study was conducted to determine the spectrum of chest trauma and its associated factors among patients admitted to King Khalid University Hospital, Riyadh, Saudi Arabia. Methods: A quantitative observational cross-sectional analysis was performed, data obtained from the medical records of the chest trauma patients which were admitted in the thoracic surgery unit, King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia from January 2013 to Jan 2019. The records of all these patients were reviewed and data were collected and analyzed prospectively. Results: A total of 236 patients (male: 87.3%; mean age: 32.4 years) were included in the analyses. The majority of these chest trauma cases (n=205; 86.9%) were caused by road traffic accidents (RTA). Blunt trauma predominated the cases n=225 (95.3%). Ribs fracture had the highest prevalence among the chest injuries with a number of 150 (63.5%) followed by lung contusion 140 (59.3%). Pneumothorax occurred in 131 (55.5%) and hemothorax occurred in 80 (33.8%) with most common indication for emergency thoracotomy. Extra-thoracic injuries involving the head/brain, limbs, and abdominal organs occurred in 189 (80%). 130 (55%) were intubated and ventilated, and almost half of the patients 115 (48.7%) were required a chest tube insertion. Conclusions: Chest trauma is a major health issue particularly in young male adults and road traffic accidents are the leading cause of chest trauma in Saudi Arabia. Early recognition of the patterns, etiology and appropriate management of trauma reduce the incidence of chest trauma related injuries. doi: https://doi.org/10.12669/pjms.37.2.3842 How to cite this:Hajjar WM, Al-Nassar SA, Almutair OS, Alfahadi AH, Aldosari NH, Meo SA.

Background: The neuropsychological tests and its subtests are composed of the motor planning task; simple reaction time task and the intradimensional/extradimensional shift (IED) task from the Cambridge Neuropsychological Test Automated Battery (CANTAB) were developed to examine specific components of cognition. The main objective of this study was to examine the reliability of these CANTAB subtests in pediatric patients with learning disabilities (LD) in Saudi Arabia. Methods: We administered the CANTAB subset test to 92 participants with LD and 68 controls with no LD. The tests performed were motor planning task (MOT), simple reaction time task (SRT) and the intradimensional/extradimensional shift (IED). Results: There was no significant age difference between the case and the control group (case: 9.2 ± 2.4 years versus controls: 9.0 ± 1.6 years, p=0.544). The IED and MOT were significantly longer among patients with LD versus control (p <0.001). LD cases had a longer SRT time than controls (cases: 1050.4 ± 626.5 versus controls: 815.5 ± 133.9, p=0.003). LD patients completed an average of 3.0 stages, than the controls, who were able to complete a mean of 8.4 IED stages (p<0.001). SRT was significantly longer in the case group (965.9 ± 716.4) compared to the controls (747.7 ± 120.7, p=0.014). LD cases made more errors in the motor screening tasks (MOT-Error) compared to the control group (case: 14.6 ± 4.5 versus controls: 12.4 ± 2.7, p<0.001). Conclusion: Patients with LD have poor CANTAB subtest results. If these CANTAB subtests do measure cognitive function, this adds to the accumulating evidence of cognitive impairment association in LD, and such studies should remain an active area of research.
