Seasonal differences in physical activity, sedentary behaviour, and sleep patterns in people with type 1 diabetes in Kuwait.

AIMS: The main aim of the current study was to measure physical activity, sedentary behaviors and sleep levels across the different seasons in people with type 1 diabetes in Kuwait. METHODS: A prospective cross-sectional study was conducted from August 2021 to September 2022. Physical activity and sleep metrics were measured over a 7-day period with a wrist-worn accelerometer (GENEActiv). Overall physical activity was measured as a Euclidean Norm Minus One in milli gravitational units (mg). Accelerometer metrics were compared across the seasons and between the sex. RESULTS: A total of 784 people with type 1 diabetes participated. Mean daily physical activity was 25.2 mg (SD = 7.3). Seasonal differences were seen in overall physical activity (p = 0.05), inactivity (p = 0.04), light activity (p = 0.001), the intensity gradient (p = 0.001) and sleep efficiency (p = 0.02). Poorer metrics were generally seen in Spring and Summer. Overall physical activity, moderate and vigorous physical activity, and inactivity were significantly higher in males compared to females (p ≤ 0.02). Females had a longer sleeping duration (p = 0.02), and higher sleep efficiency (p = 0.04) and light physical activity (p = 0.01). Overall physical activity and the intensity gradient were negatively associated with HbA1c (both p = 0.01). CONCLUSIONS: Physical activity levels were generally low and sleep poor in people with type 1 diabetes in Kuwait and these varied by sex and season. The current data are useful to target and develop interventions to improve physical activity and glycemic control.

Assessment of knowledge, accessibility, and adherence to the use of personal protective equipment and standard preventive practices among healthcare workers during the COVID-19 pandemic.

Background: Healthcare workers are at risk of acquiring infectious agents while providing services to patients. Thus, the need for evaluating and closely monitoring healthcare worker knowledge, perception, and adherence levels is critical. This study evaluates the knowledge, accessibility, and adherence regarding personal protective equipment (PPE) and preventive protocols among healthcare workers during the COVID-19 pandemic. Design and methods: A web-based cross-sectional survey was conducted from March to September 2021. The study participants were 187 healthcare workers who replied to a 31-item questionnaire using an online tool. Results: A total of 187 participants responded to the questionnaire. Most of the participants 102 (54.5%) were in the age group of 25-34 years. Of the 187 participants, 98 (52.4%) were medical doctors, and 92 (49.2%) had correct knowledge regarding donning and doffing of PPE. The vast majority (93.7%) had access to essential PPE. The average adherence level was 82.1%. Accessibility (p = 0.003) and adherence (p < 0.01) were found to be significantly high in older age participants. Conclusion: The study showed most of the healthcare workers had appropriate knowledge and, they also adhered to the proper use of PPE and infection control protocols. However, few of them identified with poor knowledge about COVID-19, inappropriate doffing of PPE, non-adherence to the protocol, and unacceptable practices. We recommend the provision of adequate training that will lead to minimizing the risk of exposure to and transmission of COVID-19 among healthcare providers.

Amphetamine-Related Fatalities and Altered Brain Chemicals: A Preliminary Investigation Using the Comparative Toxicogenomic Database.

Amphetamine is a psychostimulant drug with a high risk of toxicity and death when misused. Abuse of amphetamines is associated with an altered organic profile, which includes omega fatty acids. Low omega fatty acid levels are linked to mental disorders. Using the Comparative Toxicogenomic Database (CTD), we investigated the chemical profile of the brain in amphetamine-related fatalities and the possibility of neurotoxicity. We classified amphetamine cases as low (0-0.5 g/mL), medium (>0.5 to 1.5 g/mL), and high (>1.5 g/mL), based on amphetamine levels in brain samples. All three groups shared 1-octadecene, 1-tridecene, 2,4-di-tert-butylphenol, arachidonic acid (AA), docosahexaenoic acid (DHA), eicosane, and oleylamide. We identified chemical-disease associations using the CTD tools and predicted an association between DHA, AA and curated conditions like autistic disorder, disorders related to cocaine, Alzheimer's disease, and cognitive dysfunction. An amphetamine challenge may cause neurotoxicity in the human brain due to a decrease in omega-3 fatty acids and an increase in oxidative products. Therefore, in cases of amphetamine toxicity, a supplement therapy may be needed to prevent omega-3 fatty acid deficiency.

Knowledge, Attitudes, and Practices of High-Risk Patients towards Prevention and Early Detection of Chronic Kidney Disease (CKD) in Saudi Arabia.

CONTEXT: Chronic kidney disease (CKD) is characterized by the presence of kidney damage or decreased kidney function. In the Kingdom of Saudi Arabia, the prevalence of CKD is at 5.7%, which represents a high burden on health care systems. AIMS: This study aimed to assess the knowledge, attitudes, and practices of high-risk patients towards prevention and early detection of chronic kidney disease in Saudi Arabia. SETTING AND DESIGN: Descriptive cross-sectional study in Saudi Arabia. METHODS AND MATERIAL: This study was designed using a newly developed instrument, the CKD Screening Index. It was conducted from December 2021 to May 2022 by a self-administered questionnaire. The questionnaire has three parts: socio-demographic data, clinical factors, and the CKD screening index tool. STATISTICAL ANALYSES USED: Independent t-test, One-Way ANOVA, LSD, Games-Howell tests. RESULTS: Knowledge of kidney function had a significant difference across patient groups with varying employment status. Monthly income is a significant factor for the patient attitude on healthcare towards preventing kidney disease. On the other hand, educational level significantly affects the overall attitude of patients towards preventing kidney disease. CONCLUSION: Understanding knowledge, attitudes, and practices associated with CKD is vital to informing optimal policy and public health responses in the country.

Multi-Compartment 3D-Cultured Organ-on-a-Chip: Towards a Biomimetic Lymph Node for Drug Development.

The interaction of immune cells with drugs and/or with other cell types should be mechanistically investigated in order to reduce attrition of new drug development. However, they are currently only limited technologies that address this need. In our work, we developed initial but significant building blocks that enable such immune-drug studies. We developed a novel microfluidic platform replicating the Lymph Node (LN) microenvironment called LN-on-a-chip, starting from design all the way to microfabrication, characterization and validation in terms of architectural features, fluidics, cytocompatibility, and usability. To prove the biomimetics of this microenvironment, we inserted different immune cell types in a microfluidic device, which showed an in-vivo-like spatial distribution. We demonstrated that the developed LN-on-a-chip incorporates key features of the native human LN, namely, (i) similarity in extracellular matrix composition, morphology, porosity, stiffness, and permeability, (ii) compartmentalization of immune cells within distinct structural domains, (iii) replication of the lymphatic fluid flow pattern, (iv) viability of encapsulated cells in collagen over the typical timeframe of immunotoxicity experiments, and (v) interaction among different cell types across chamber boundaries. Further studies with this platform may assess the immune cell function as a step forward to disclose the effects of pharmaceutics to downstream immunology in more physiologically relevant microenvironments.

Postnatal exercises: perceived barriers and self-efficacy among women at maternal and children hospital at Najran, kingdom of Saudi Arabia.

Sedentary lifestyle is very high in the Saudi population in general and significantly high among females. Furthermore, some postpartum tradition imposes limited activities during postpartum periods. For women to be active during the postpartum period, they should have enough self-efficacy (SE) to overcome perceived barriers (BP). This study aimed to evaluate postnatal exercises' PB and SE among postpartum women. A descriptive cross-sectional research design was followed in this study. This study was conducted at the outpatient department/ Maternal and Child hospital in Najran city, KSA. The study comprised a convenience sample of 368 postnatal women. Data collection was done using a questionnaire composed of three parts; socio-demographic data and obstetric history, exercise benefits/barriers scale and exercise self-efficacy scale. Data were analyzed using SPSS 23.0. The relationships between variables were assessed using the Chi-square or Fisher's exact test. The correlations were assessed using Pearson correlation. The study results illustrated that 52.4% of the postpartum women had moderate SE to exercise, and 71.5% had moderate PB. Also, there were statistically significant relationships between the study participants' SE and PB and their educational level and nationality (p <0.05). In addition, significant negative correlations existed between the participants' SE and their Body Mass Index (BMI), age, gravidity, parity, number of children, and PB (p <0.05). On the other hand, significant positive correlations were observed between the participants' PB and their BMI, age, gravidity, parity, and number of children. This study concluded that about two-thirds of the postpartum women in Najran had low or moderate SE to practice postnatal exercises, and the majority of them had moderate or high BP. Efforts to enhance postnatal exercises should be directed to increase SE to overcome BP concerning postnatal exercises.
