RESUMEN

Introduction: Type 1 diabetes mellitus (T1DM) is a chronic auto-immune disease in which loss of pancreatic islet ß-cells leads to the deficiency of insulin in the body thus resulting in enhanced blood sugar levels. Effective blood glucose monitoring is crucial in T1DM management to prevent complications, particularly hypoglycemia. Method: The study adopted a cross-sectional survey to assess satisfaction and quality of life among T1DM patients using the freestyle libre continuous glucose monitoring (FSL-CGM), and a retrospective cohort study design to evaluate changes in HbA1c over a year. Result: The study involved 98 Saudi subjects, with 46.9% (n = 46) being male. The results indicated a high level of user satisfaction, with more than 85% of the participants responding positively, yielding a total satisfaction score of 30.86. User satisfaction with FSL-CGM was found to be significantly associated with the level of education. The use of FSL-CGM was also found to significantly improve the patients' quality of life. However, the levels of HbA1c had an impact on both satisfaction and quality of life. Before using the FSL-CGM system, the mean HbA1c was 9.83%, which significantly decreased to 8.63% after using the system (P-value <0.001). Conclusion: The study's findings align with previous literature on satisfaction and quality of life, but there are conflicting results regarding the reduction of HbA1c levels using FSL-CGM. Given the limited sample size, future research could explore the topic more comprehensively, potentially utilizing a longitudinal study design to better measure changes in HbA1c level.

RESUMEN

BACKGROUND: Several studies proved the effectiveness of Severe Acute Respiratory Syndrome Corona Virus (SARS-CoV-2) vaccines; however, the number of doses and the period between doses that warrant the highest protection remain unclear. This study aims to assess the effectiveness of the Pfizer-BioNTech vaccine and to evaluate the effectiveness of early and delayed second-dose administration of the vaccine. METHODS: This is a retrospective cohort study that was conducted using the data from March 1st, 2021, to August 31st, 2021. Data regarding vaccination coverage and confirmed SARS-CoV-2 infection were obtained using academic hospitals databases and Health Electronic Surveillance Network (HESN) platform. The vaccination status of the participants were categorized as: unvaccinated, vaccinated 1st dose, and vaccinated 2nd dose of Pfizer-BioNTech vaccine. The outcome of interest was positive polymerase chain reaction test for SARS-CoV-2. Generalized linear model with a Poisson distribution was used to estimate the incidence of the infection. FINDINGS: Among 66,775 participants included, 2615 SARS-CoV-2 infections were observed. The sample was relatively young with median age of 22 years and 43% female. A single dose of Pfizer-BioNTech vaccine had 40 % effectiveness. The effectiveness of the vaccine was doubled after the second dose of Pfizer-BioNTech (80 %). The time between the first and the second dose appears to be crucial after observing 75 %, 90 % and 85 % effectiveness with early vaccination, on-time vaccination, and delayed vaccination, respectively. CONCLUSION: For Pfizer-BioNTech vaccine recipients in Saudi Arabia, particularly among a predominantly young population, higher effectiveness against SARS-CoV-2 was observed with two doses of the vaccine. The timing of the second dose appears crucial for the extent of protection against SARS-CoV-2. However, potential residual confounding cannot be discounted, and further studies are needed to validate these findings and improve generalizability.

RESUMEN

Introduction: Younger generations are an important market for the tobacco products industry since most smokers try their first cigarette before the age of 18. Electronic cigarettes (e-cigarettes) are a common mode of smoking among teens, and the number of users is increasing exponentially. Objective: This study aimed to estimate the current prevalence of e-cigarettes and vaping usage among adolescents between the ages of 15 and 19 in the city of Mecca, Saudi Arabia. Methods: This study was conducted among 534 students at four high schools. They were asked to complete a 23-item questionnaire retrieved from the Global Youth Tobacco Survey. Descriptive statistics and regression analysis were conducted. The study was approved by the Ministry of Health Saudi Arabia Medical Research Center Institutional Review Board committee on October 10, 2018 (research number 18-506E). Results: A total of 109 (20.6%) of the participants reported being smokers of e-cigarettes. Being a male (OR = 1.55; 95% CI: [1.01-2.37]), in the second year of high school (OR = 2.91; 95% CI: [1.61-5.24], ever experimenting with regular tobacco cigarettes, being a current shisha smoker, living with a smoker, and believing that e-cigarettes are less addictive than traditional cigarettes are all factors independently associated with e-cigarette use in this sample of adolescents. Conclusion: Among adolescent smokers, even minimal experience with smoking is correlated with pro-smoking attitudes. E-cigarette use is common in adolescents and related to the use of other combustible tobacco products. Tobacco control efforts at all levels should eliminate factors fostering future tobacco use to minimize the burden of disease and disability in vulnerable populations.

RESUMEN

Diabetes mellitus is linked to both short-term and long-term health problems. Therefore, its detection at a very basic stage is of utmost importance. Research institutes and medical organizations are increasingly using cost-effective biosensors to monitor human biological processes and provide precise health diagnoses. Biosensors aid in accurate diabetes diagnosis and monitoring for efficient treatment and management. Recent attention to nanotechnology in the fast-evolving area of biosensing has facilitated the advancement of new sensors and sensing processes and improved the performance and sensitivity of current biosensors. Nanotechnology biosensors detect disease and track therapy response. Clinically efficient biosensors are user-friendly, efficient, cheap, and scalable in nanomaterial-based production processes and thus can transform diabetes outcomes. This article is more focused on biosensors and their substantial medical applications. The highlights of the article consist of the different types of biosensing units, the role of biosensors in diabetes, the evolution of glucose sensors, and printed biosensors and biosensing systems. Later on, we were engrossed in the glucose sensors based on biofluids, employing minimally invasive, invasive, and noninvasive technologies to find out the impact of nanotechnology on the biosensors to produce a novel device as a nano-biosensor. In this approach, this article documents major advances in nanotechnology-based biosensors for medical applications, as well as the hurdles they must overcome in clinical practice.

RESUMEN

BACKGROUND: Medical educators in academia have faced challenges incorporating leadership training into curricula while minimizing redundancy and assuring value and relevance for all learners. This study aims to assess the status of leadership training as perceived by family medicine residents in Riyadh to advise the development of a formal leadership training curriculum. METHOD: The research is cross-sectional and quantitative. Participants were asked via an electronic questionnaire about their leadership attitudes, perceived degree of training in various leadership domains, and where they could find additional training. RESULTS: The survey was completed by 270 family medicine residents in Riyadh. Residents rated the importance of physician leadership in their communities as high (6 out of 7 on a Likert scale). In contrast, agreement with the statement 'I am a leader' obtained the lowest grade (4.4 of 7 on a Likert scale). Overall, most of the residents participating in the study (50% or more) voiced a desire for more training in all leadership domains. Over 50% of residents indicated that leadership electives or selective lectures, workshops, or seminars as well as WADAs (Weekly Academic Day Activities), leadership mentors or coaches teaching junior learners (with training), and leadership courses could be incorporated into the curriculum to foster leadership skills. CONCLUSION: Residents were enthusiastic about family physicians being leaders, aligning with the current educational philosophy but requiring formal training. They also indicated areas where leadership training might be improved and developed in the current curriculum. This poll's results could be used to help residents build leadership skills by incorporating them into a formal leadership curriculum.

RESUMEN

Purpose Advancements in internet technology are on the rise and so is the concern for its detrimental effects on youth like cyberbullying. Cyberbullying is on the rise and may cause adverse effects on mental health. The objective of the present study was to identify the prevalence of cyberbullying and its associated risk factors and to measure its association with mental health among adolescents. Methods An online self-administered questionnaire was distributed to 761 high school students aged 15 - 19 years from Riyadh, Saudi Arabia. A quantitative cross-sectional design was integrated, and logistic regression analysis was performed to determine the association. As part of assessing mental health, a questionnaire on the use of cigarettes, e-cigarettes, and hookah was also administered. Results The prevalence of cyberbullying was 18%. Although a significant association between cyberbullying and mental health status was obtained (OR = 1.04; p =0.03), the risk of Odds was found to be weak and therefore did not favor the hypothesis. The significant risk factors associated with cyberbullying include being traditionally bullied (OR= 4.76; p = <.001), e-cigarette use (OR = 2.73; p = <.001), and male gender (OR = 1.64; p = .04). Conclusion Despite the findings not favouring the hypothesis, a few striking associations were obtained in the study. Traditional bullying and e-cigarette use increased the risk of cyberbullying. This is a matter of rising concern since e-cigarette use has witnessed a surging rise in popularity. These findings may serve as early warning on the rising issue of cyberbullying and could pave way for formulating early preventive strategies and promulgate awareness by the concerned authorities.

RESUMEN

Asthma is a chronic lung disease characterized by airway inflammation and hyper-responsiveness of airway smooth muscles. There is growing evidence that magnesium may have a role in managing asthma through its dual effect as an anti-inflammatory and bronchodilating agent. To assess the efficacy of oral magnesium supplements in chronic asthmatic patients. In addition to searching through Clinicaltrials.gov/ and references for oral magnesium supplement studies, we performed a database search in Medline, CINAHL, CENTRAL, and Embase. We contacted the authors of the included trials to ask for additional information. We included randomized controlled trials that compared oral magnesium supplements versus placebo, in addition to standard asthma treatment in mild-moderate asthmatic adults and children (older than 6 years). Two reviewers independently performed the study selection, data abstraction, and the assessment of the risk of bias. Eight trials at moderate risk of bias enrolling a total of 917 patients were included. Oral magnesium improved FEV1 at week 8 (5.69 (L/min); 95% CI: 1.92, 9.46; I2: 45%). There was no significant improvement in FEV1 at other follow up periods. There was no significant change in FVC, Methacholine challenge test, the frequency of bronchodilator use, or symptoms score. There were no data on mortality or quality of life. Oral magnesium supplements may lead to improvement in FEV1 that was only demonstrated at eight weeks; but no effect on any other outcome. Until future evidence emerges, oral magnesium cannot be recommended as adjuvants to standard treatment for mild to moderate asthmatic individuals.

RESUMEN

OBJECTIVES: To examine the associations between sleep duration and a variety of demographic and clinical variables in a sample of Saudi adults.  Methods: A cross-sectional study among 2,095 participants was conducted at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia, between May and October 2014. A questionnaire was administered to collect data related to clinical health outcomes and demographic characteristics. Participants were asked to report their average sleep duration per night in hours.  Results: One-third (33.8%) reported short sleep duration of less than 7 hours/night. Short sleep duration was more prevalent in females (37.3% versus 31.4%, p=0.004). The most common medical problems reported were obesity with body mass index of greater than 30 Kg/m2 (39.1%), hypertension (33.9%), diabetes mellitus (20.8%), depression (4.3%), asthma (17.3%), COPD (6.6%), and hyperlipidemia (2.7%). Diabetes mellitus was associated with long sleep of more than 9 hours/night (25.4%, p=0.011) and hypertension (54.2%, p=0.001). The linear regression model tend to reduce their sleep duration by roughly 22 minutes in female gender, 66 minutes in participants with hyperlipidemia, and 70 minutes in participants with poor sleep quality.  Conclusions: Short sleep duration per night was prevalent, it affects one in every 3 Saudi adults. Long sleep duration of more than 9 hours was associated with increased comorbid conditions.
