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.
BackgroundCoronavirus disease 2019 (COVID-19) is an infectious disease that is associated with many health conditions, including, but not limited to, dermatological diseases. Some patients suffer from hair loss after becoming infected with severe acute respiratory syndrome coronavirus 2. Acute telogen effluvium (TE) is a non-scarring hair loss that usually occurs three months after a stressful event and can last up to six months, and it can be associated with post-COVID-19 infections. This study aims to explore the prevalence of hair loss among recovered COVID-19 patients in Saudi Arabia and determine the contributing factors. Furthermore, we aimed to measure the impact of hair loss after COVID-19 on their quality of life. MethodologyAn observational, cross-sectional study was conducted from September to December 2021 in Saudi Arabia. A questionnaire was used to assess hair loss after being infected with COVID-19. Furthermore, quality of life was assessed using the Dermatology Life Quality Index (DLQI) questionnaire. Participants were recruited by sharing the questionnaire on social media platforms (Twitter, Telegram, and WhatsApp). The data were analyzed using SPSS version 23 (IBM Corp., Armonk, NY, USA). Frequency and percentages were used to display categorical variables, while minimum, maximum, mean, and standard deviation were used to present continuous variables. The categorical variables were compared using a chi-square test, and the statistical significance cut-off was set at p < 0.05. ResultsA total of 806 participants were included in the study, of whom 52.7% experienced hair loss after COVID-19 infection. Age, gender, high temperature during, and the presence of hair loss prior to infection were significantly associated with the incidence of TE. The severity of life affection based on DLQI showed that 91.4% of the participants did not have severe life affection, while 8.6% had their lives severely affected. ConclusionsThis study revealed subjective hair loss that was significantly associated with high temperature, being female, and having a history of previous hair loss. Further studies using objective assessments are suggested for reaching more precise conclusions.
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.
