Point prevalence survey of antibiotics use among hospitalised neonates and children in Saudi Arabia: findings and implications.

Background: Neonates and children are more susceptible to a variety of infections, leading to frequent antibiotic prescriptions. However, the inappropriate use of antibiotics leads to antibiotic resistance and higher mortality rates. Therefore, this study aimed to determine the prevalence of antibiotic use, and current antibiotic prescribing practices among neonates and children admitted in the selected hospitals of Saudi Arabia. Methods: A cross-sectional study was conducted from September to November 2023 to assess the prevalence of antibiotic use, and the current antibiotic prescribing practices across six hospitals of Saudi Arabia. Results: The study included 499 children and neonates, with 94.6% receiving antibiotic prescriptions. The most frequently prescribed antibiotic class was third-generation cephalosporin (31.5%), with ceftriaxone being the most commonly prescribed antibiotic (15%). The majority of patients were prescribed one antibiotic (81.4%), and the intravenous route (96.4%) was the primary route for administration. The majority of patients were prescribed antibiotics empirically (69.7%), and community-acquired infections (64.2%) were the most common type of infection for antibiotic prescription. Similarly, sepsis (39.2%) was the most common indication for antibiotics, and the majority of prescribed antibiotics (61.7%) belonged to the 'Watch' category as per WHO AWaRe classification. Conclusion: Our study revealed excessive antibiotic consumption in neonates and children, therefore quality improvement programmes including antimicrobial stewardship programmes are urgently needed to address ongoing issues.

GIS-based multi-criteria decision models for barite exploration in Nigeria's Benue Trough.

Spatial predictive mapping using geographic information system (GIS) is considered an invaluable tool for reconnaissance-scale exploration of mineral resources. In this study, geospatial data on geophysics, remote sensing, and structural and lithological attributes were systematically integrated to prospect barite potential zones within the Mid-Nigerian Benue Trough (MBT). Correlation attribute evaluation was used to establish the relationship between mineral deposit occurrences and geospatial data, while data integration was implemented using the Multi-Objective Optimization by Ratio Analysis (MOORA), Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), and Additive Ratio Assessment (ARAS) multi-criteria models. Here we show that the correlation attribute evaluation suggests that barite occurrences displayed a strong correlation with spatial data on lineament density, ferric iron alteration, and potassium to thorium (K/Th) ratio, whereas a weak correlation was observed with spatial data on the first vertical derivative (FVD), proximity to the host rock, and ferrous iron alteration. Here we report that the quantitative estimation of predictive models indicated that very high predictive zones for barite occurrences accounted for 19% of all the models. The accuracy assessment using Receiver Operating Characteristic (ROC)/Area Under the Curve (AUC) showed prediction levels above 78% for all models. The effectiveness of the spatial application of multi-criteria decision models makes them a reliable tool for barite exploration within the Mid-Nigerian Benue Trough (MBT) and other geologically similar environments.

Exploring the Impact of Iron Deficiency Anaemia on Glycated Haemoglobin A1c Levels in Pregnant and Non-Pregnant Women: A Systematic Review.

Haemoglobin A1C (HbA1c) is fundamental in monitoring glycaemic control during pregnancy. However, several conditions could affect this test's accuracy, including iron deficiency anaemia (IDA). Hence, this systematic review delves into the underexplored connection between IDA, iron replacement therapy (IRT), and haemoglobin A1C (HbA1c) during pregnancy. An electronic search of the Cochrane, MEDLINE, and Embase databases was conducted by six authors. From a comprehensive search strategy, 968 records were obtained. After applying the inclusion and exclusion criteria, seven studies were included, comprising 365 women selected for analysis. Six studies indicated a positive correlation between IDA and HbA1c levels, while one found no correlation. The average HbA1c level of the included studies in pregnant women was 5.64%. In comparison, it was found that non-pregnant women had lower HbA1c levels. Among the included studies, the mean HbA1c levels decreased from 5.1% to 4.89% after treating pregnant women with IRT. The review emphasises the complexity of interpreting HbA1c levels in pregnant women with IDA, highlighting the influence of pregnancy-induced physiological changes. In addition, this suggests that HbA1c should not be the sole criterion for diabetes management in pregnant women with IDA. Future research should focus on alternative glycaemic monitoring methods unaffected by IDA.

Modified sutureless and glue-free method versus conventional sutures for conjunctival autograft fixation in primary pterygium surgery: a systematic review and meta-analysis.

BACKGROUND: Pterygium is a common ocular surface disorder that requires surgical intervention for treatment. Conjunctival autografts are preferred over simple excision due to lower recurrence rates. This systematic review and meta-analysis compared the modified sutureless glue-free (MSGF) method with conventional sutures (CS) for conjunctival autograft fixation in primary pterygium surgery. METHODS: A comprehensive search was conducted in MEDLINE, Embase, CENTRAL, Google Scholar and ClinicalTrials.gov for randomised controlled trials (RCTs) comparing MSGF and CS conjunctival autografts. Outcome measures included operation time, recurrence and postoperative complications. Standardised mean difference (SMD) and risk ratio (RR) were used for continuous and dichotomous outcomes, respectively. RESULTS: 11 RCTs involving 833 participants were included. The analysis revealed that MSGF had a significantly shorter operation time compared with CS (SMD -3.704, 95% CI -5.122 to -2.287, p<0.001). CS was associated with a higher risk of foreign body sensation (RR 0.22, 95% CI 0.06 to 0.74, p=0.01). MSGF was associated with a higher risk of graft dehiscence (RR 9.01, 95% CI 2.74 to 29.68, p=0.000) and graft retraction (RR 2.37, 95% CI 1.17 to 4.77, p=0.02). No significant differences were found in recurrence, graft haemorrhage, granuloma, Dellen and conjunctival oedema. CONCLUSION: Using the MSGF technique in conjunctival autograft fixation for pterygium surgery reduces operation time by relying solely on the patient's blood for fixation. However, it increases the risk of graft dehiscence and retraction. However, CS is linked to a higher likelihood of experiencing foreign body sensations. Understanding the learning curve and surgeon familiarity with novel techniques is crucial for optimising patient care and surgical outcomes, while individualised decision-making is necessary considering the advantages and disadvantages of each approach. Further research is warranted to minimise complications and optimise surgical outcomes.

Understanding Khat: Its Sociocultural and Health Implications in Saudi Arabia.

This review offers an insight into the historical background, utilization, chemical composition, health impacts, processes, and cultural aspects associated with the usage of khat, a psychoactive, mind-altering plant indigenous to the Arabian Peninsula and the Horn of Africa. It further explores the cultural importance of khat in nations such as Saudi Arabia, Yemen, Ethiopia, and Somalia, detailing its chemical makeup containing alkaloids and other compounds, its physiological impact on the body, and its potential health risks like cardiovascular complications, mental health disorders, and dental problems. The cultural, economic, and religious aspects that affect perceptions and consumption of khat were also considered while emphasizing its usage despite legal bans in many nations.

Comparison of the efficacy of propranolol versus amitriptyline as monotherapy for prophylaxis of migraine.

Background: Approximately 15% of migraine sufferers need preventative medicine because they have more than two episodes each month. Migraine is a regular, persistent condition that frequently makes victims helpless. Numerous drugs from various classes have so far been used in migraine prophylaxis. Their effectiveness is recurrently overshadowed by their side effects because they must be used for a long time, which occasionally necessitates stopping the drug. Materials and Methods: In the tertiary care teaching hospital's department of medicine, a prospective, comparative, open-label study was initiated. Two groups of 80 patients were randomly chosen. For 3 months, the 40 patients in Group A were given a tablet of amitriptyline 10 mg once daily, whereas the 40 patients in Group B were given a tablet of propranolol 20 mg once a day. At the conclusion of the fourth, eighth, and twelfth weeks, the patients' own self-assessment migraine diary and a 4-point pain scale were used to grade the intensity of the headaches. Results: As a result, in Group A, the mean migraine attack severity in periods 1 and 2 was 5.88 2.69 and 5.41 2.48, respectively. In Group B, the mean was 5.15 2.75 in period 1 and 5.66 2.78 in period 2, respectively. The average length of a migraine attack in Group A was 20.30 5.61 h in period 1 and 16.75 5.23 h in period 2. In Group B, the mean was 16.59 3.21 in period 1 and 18.78 5.14 in period 2. Between groups A and B, there was a statistically significant difference. Conclusion: The average number of migraine attacks reduced in the amitriptyline and propranolol groups as the treatment duration increased. Amitriptyline is a popular medication with established effectiveness and manageable levels of negative side effects. It is the tricyclic antidepressant that is most frequently used to prevent headaches. When administered for migraine prevention, it generates a quick response within 3 months. Propranolol is less effective than amitriptyline at reducing the frequency, length, and severity of episodes.

Knowledge of Thyroid Disease Manifestation and Risk Factors Among the General Population in the Tabuk Region of Saudi Arabia.

Background Thyroid disorders are caused either by excessive or inadequate thyroid hormone production or by the enlargement of the thyroid gland. Various types of thyroid disorders exist, including primary (related directly to the gland itself), secondary (related to thyroid function), and other types. This study aimed to assess the knowledge of thyroid disease manifestation and its risk factors among individuals living in Tabuk, Saudi Arabia. Methodology An observational cross-sectional study was conducted among 400 adults living in Tabuk city of Saudi Arabia aged 18 years or above. Data was collected using an electronic questionnaire through a simple random sampling method. Data was then coded, entered, and analyzed using both descriptive and inferential statistical methods using IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States). Results A total of 403 participants were enrolled in this study. More than half (n=265, 65.8%) were females, and 188 (46.7%) were in the age group of 18-35 years. The educational level of the majority of them was a bachelor's degree (n=296, 73.4%). Hypothyroidism was the most common thyroid disorder among family members (n=51, 62.4%). Inadequate iodine intake was thought to be a risk factor for thyroid disorders, as mentioned by 276 (68.5%) participants. Exact 284 (70.5%) participants believed that females are more at risk of having thyroid disease. The mean total knowledge score was found to be 25.1±4.48 out of a total of 34. Exact 216 (53.6%) participants had good knowledge about thyroid disorders. The female gender had significantly higher levels of knowledge as compared to males (p-value=0.002) regarding the manifestation and risk factors of thyroid disorders. In terms of educational level, a bachelor's or above was found to be significantly associated with a higher level of knowledge (p-value=0.003). Conclusion A good level of knowledge and awareness about thyroid disorders was observed among more than half of the participants. Few knowledge gaps were identified regarding knowledge about symptoms of hypothyroidism and certain medications which might cause thyroid disorders.

Awareness of Risk Factors for Coronary Artery Disease in the Population of Al-Majma'ah Region, Saudi Arabia.

BACKGROUND: Coronary artery disease (CAD) is a significant global health concern and a leading cause of morbidity and mortality. As a complex cardiovascular condition, CAD arises from the accumulation of atherosclerotic plaques within the coronary arteries, leading to restricted blood flow to the heart muscle. While CAD has been extensively studied, its prevalence remains a challenge, particularly in diverse populations with distinct cultural and lifestyle practices. OBJECTIVES:  To assess the awareness of risk factors for CAD in the population of Al-Majma'ah Region, Saudi Arabia. METHODS:  The purpose of this cross-sectional descriptive study was to determine participants' awareness of CAD risk factors among the population of Al-Majma'ah Region, Saudi Arabia. It was conducted by the use of a self-administered questionnaire that had been validated in prior research publications. Sociodemographic information as well as the prevalence of cardiovascular disease risk factors were covered in the survey. The data analysis was done using IBM SPSS Statistics for Windows, Version 26 (Released 2019; IBM Corp., Armonk, New York, United States). RESULTS: A total of 919 individuals were enrolled in the current study after meeting the inclusion criteria. The results showed that most of the respondents 626 (68.1%) had a good level of awareness, 261 (28.4%) had a fair level of awareness, while only 32 (3.5%) of the respondents had a poor level of CAD risk factors awareness. CONCLUSION: The majority of participants had a good level of knowledge regarding CAD risk factors. The correlation between monthly income and awareness of coronary artery risk factors was statistically significant.

A Systematic Evaluation of the Quality of Health Information on Cleft Lip and Palate in the Arabic Language.

Background: The internet serves as a vital health information resource, yet the quality of data on specific health conditions, especially in Arabic, is often overlooked. This research assesses the quality of Arabic online information about cleft lip and palate (CLP) and proposes avenues for enhancement. Methods: From July to August 2022, a systematic evaluation of Arabic articles on CLP was performed using the DISCERN tool for quality assessment. Searches on Google and Bing resulted in 119 articles that met the study's criteria. Results: The quality of available Arabic information on CLP displayed substantial gaps. Commercial sources dominated (49.6%), followed by private (32.8%) and nonprofit entities (17.6%). The average DISCERN score was 2.26 of 5 (SD = 1.06), indicating the need for enhanced content, particularly concerning treatment risks. Conclusions: The study underscores the subpar quality of Arabic CLP information online, which might mislead patients and impede access to accurate advice. Nonprofit organizations should bolster their online footprint, offering refined health content. A deep dive into DISCERN scores reveals pinpointed improvement areas. Clinicians should direct patients and their families to reliable information sources. Addressing these gaps promises improved CLP knowledge in Arabic, fostering superior patient education and outcomes for those with this condition.

Ranking and filtering of neuropathology features in the machine learning evaluation of dementia studies.

Early diagnosis of dementia diseases, such as Alzheimer's disease, is difficult because of the time and resources needed to perform neuropsychological and pathological assessments. Given the increasing use of machine learning methods to evaluate neuropathology features in the brains of dementia patients, it is important to investigate how the selection of features may be impacted and which features are most important for the classification of dementia. We objectively assessed neuropathology features using machine learning techniques for filtering features in two independent ageing cohorts, the Cognitive Function and Aging Studies (CFAS) and Alzheimer's Disease Neuroimaging Initiative (ADNI). The reliefF and least loss methods were most consistent with their rankings between ADNI and CFAS; however, reliefF was most biassed by feature-feature correlations. Braak stage was consistently the highest ranked feature and its ranking was not correlated with other features, highlighting its unique importance. Using a smaller set of highly ranked features, rather than all features, can achieve a similar or better dementia classification performance in CFAS (60%-70% accuracy with Naïve Bayes). This study showed that specific neuropathology features can be prioritised by feature filtering methods, but they are impacted by feature-feature correlations and their results can vary between cohort studies. By understanding these biases, we can reduce discrepancies in feature ranking and identify a minimal set of features needed for accurate classification of dementia.

Helicobacter pylori and oral-gut microbiome: clinical implications.

More than half of the world's population are colonized with H. pylori; however, the prevalence varies geographically with the highest incidence in Africa. H. pylori is probably a commensal organism that has been associated with the development of gastritis, ulcers, and gastric cancer. H. pylori alone is most probably not enough for the development of gastric carcinoma, but evidence for its association with the disease is high and has, therefore, been classified by the International Agency for Research on Cancer as a Class 1 carcinogen. Bacteroidetes and Fusobacteria positively coexisted during H. pylori infection along the oral-gut axis. The eradication therapy required to treat H. pylori infection can also have detrimental consequences for the gut microbiota, leading to a decreased alpha diversity. Therefore, therapy regimens integrated with probiotics may abolish the negative effects of antibiotic therapy on the gut microbiota. These eradication therapies combined with probiotics have also higher rates of eradication, when compared to standard treatments, and are associated with reduced side effects, improving the patient's compliance. The eradication therapy not only affects gut microbiome but also affects the oral microbiome with robust predominance of harmful bacteria. However, there have been reports of a protective role of H. pylori in Barrett's esophagus, esophageal adenocarcinoma, eosinophilic esophagitis, IBD, asthma, and even multiple sclerosis. Therefore, eradication therapy should be carefully considered, and test to treat policy should be tailored to specific communities especially in highly endemic areas. Supplementation of probiotics, prebiotics, herbals, and microbial metabolites to reduce the negative effects of eradication therapy should be considered. After failure of many eradication attempts, the benefits of H. pylori eradication should be carefully balanced against the risk of adverse effects especially in the elderly, persons with frailty, and intolerance to antibiotics.

Comparing the safety and effectiveness of various umbilical cord milking techniques and delayed cord clamping in full-term and preterm infants: A systematic review and meta-analysis.

We compare the hematocrit, hemoglobin, need for transfusion, recurrent phototherapy, serum bilirubin level, and serum ferritin at different time frames for the umbilical cord milking (UCM) and delayed cord clamping (DCC) in both full-term and preterm infants. A comprehensive search through various databases aimed to compare UCM and DCC studies until May 2nd, 2023. Cochrane and NIH tools assessed RCTs and cohorts, respectively. Meta-analysis employed Review Manager 5.4 software, calculating MD and RR with 95% CIs for continuous and dichotomous data. We included 20 studies with a total of 5189 infants. Regarding preterm infants, hematocrit level showed no significant difference between intact Umbilical Cord Milking (iUCM) compared to DCC (MD = -0.24, 95% CI [-1.11, 0.64]). Moreover, Neonatal death incidence was significantly higher with the UCM technique in comparison to DCC (RR = 1.28, 95% CI [1.01 to 1.62]). Regarding term and late preterm infants, Hematocrit level showed no significant difference between the iUCM or cUCM techniques compared to DCC (MD = 0.21, 95% CI [-1.28 to 1.69]), (MD = 0.96, 95% CI [-1.02 to 2.95]), respectively. UCM led to a higher risk of neonatal death in preterm infants compared to DCC. However, the incidence of polycythemia was lower in the UCM group. Additionally, UCM was associated with higher rates of severe IVH events. Based on these findings, DCC may be preferred due to its lower incidence of severe IVH and neonatal death.

Nous comparons l'hématocrite, l'hémoglobine, le besoin de transfusion, la photothérapie récurrente, le taux de bilirubine sérique et la ferritine sérique à différentes périodes pour la traite du cordon ombilical (UCM) et le clampage retardé du cordon (DCC) chez les nourrissons nés à terme et prématurés. Une recherche complète dans diverses bases de données visait à comparer les études UCM et DCC jusqu'au 2 mai 2023. Les outils Cochrane et NIH ont évalué les ECR et les cohortes, respectivement. La méta-analyse a utilisé le logiciel Review Manager 5.4, calculant le MD et le RR avec des IC à 95 % pour les données continues et dichotomiques. Nous avons inclus 20 études portant sur un total de 5 189 nourrissons. Concernant les nourrissons prématurés, le niveau d'hématocrite n'a montré aucune différence significative entre la traite du cordon ombilical intact (iUCM) et la DCC (DM = -0,24, IC à 95 % [-1,11, 0,64]). De plus, l'incidence des décès néonatals était significativement plus élevée avec la technique UCM qu'avec la technique DCC (RR = 1,28, IC à 95 % [1,01 à 1,62]). Concernant les nourrissons à terme et peu prématurés, le niveau = 0,21, IC à 95 % [-1,28 à 1,69]), (DM = 0,96, IC à 95 % [-1,02 à 2,95]), respectivement. L'UCM a entraîné un risque plus élevé de décès néonatal chez les nourrissons prématurés par rapport au DCC. Cependant, l'incidence de la polyglobulie était plus faible dans le groupe UCM. De plus, l'UCM était associée à des taux plus élevés d'événements IVH graves. Sur la base de ces résultats, le DCC peut être préféré en raison de sa plus faible incidence d'IVH grave et de décès néonatals. d'hématocrite n'a montré aucune différence significative entre les techniques iUCM ou cUCM par rapport à la technique DCC (DM.

Unsupervised machine learning to investigate trajectory patterns of COVID-19 symptoms and physical activity measured via the MyHeart Counts App and smart devices.

Previous studies have associated COVID-19 symptoms severity with levels of physical activity. We therefore investigated longitudinal trajectories of COVID-19 symptoms in a cohort of healthcare workers (HCWs) with non-hospitalised COVID-19 and their real-world physical activity. 121 HCWs with a history of COVID-19 infection who had symptoms monitored through at least two research clinic visits, and via smartphone were examined. HCWs with a compatible smartphone were provided with an Apple Watch Series 4 and were asked to install the MyHeart Counts Study App to collect COVID-19 symptom data and multiple physical activity parameters. Unsupervised classification analysis of symptoms identified two trajectory patterns of long and short symptom duration. The prevalence for longitudinal persistence of any COVID-19 symptom was 36% with fatigue and loss of smell being the two most prevalent individual symptom trajectories (24.8% and 21.5%, respectively). 8 physical activity features obtained via the MyHeart Counts App identified two groups of trajectories for high and low activity. Of these 8 parameters only 'distance moved walking or running' was associated with COVID-19 symptom trajectories. We report a high prevalence of long-term symptoms of COVID-19 in a non-hospitalised cohort of HCWs, a method to identify physical activity trends, and investigate their association. These data highlight the importance of tracking symptoms from onset to recovery even in non-hospitalised COVID-19 individuals. The increasing ease in collecting real-world physical activity data non-invasively from wearable devices provides opportunity to investigate the association of physical activity to symptoms of COVID-19 and other cardio-respiratory diseases.

Assessment of genetic diversity and phylogenetic relationship of local coffee populations in southwestern Saudi Arabia using DNA barcoding.

The genetic diversity of local coffee populations is crucial to breed new varieties better adapted to the increasingly stressful environment due to climate change and evolving consumer preferences. Unfortunately, local coffee germplasm conservation and genetic assessment have not received much attention. Molecular tools offer substantial benefits in identifying and selecting new cultivars or clones suitable for sustainable commercial utilization. New annotation methods, such as chloroplast barcoding, are necessary to produce accurate and high-quality phylogenetic analyses. This study used DNA barcoding techniques to examine the genetic relationships among fifty-six accessions collected from the southwestern part of Saudi Arabia. PCR amplification and sequence characterization were used to investigate the effectiveness of four barcoding loci: atpB-rbcl, trnL-trnF, trnT-trnL, and trnL. The maximum nucleotide sites, nucleotide diversity, and an average number of nucleotide differences were recorded for atpB-rbcl, while trnT-trnL had the highest variable polymorphic sites, segregating sites, and haploid diversity. Among the four barcode loci, trnT-trnL recorded the highest singleton variable sites, while trnL recorded the highest parsimony information sites. Furthermore, the phylogenetic analysis clustered the Coffea arabica genotypes into four different groups, with three genotypes (KSA31, KSA38, and KSA46) found to be the most divergent genotypes standing alone in the cluster and remained apart during the analysis. The study demonstrates the presence of considerable diversity among coffee populations in Saudi Arabia. Furthermore, it also shows that DNA barcoding is an effective technique for identifying local coffee genotypes, with potential applications in coffee conservation and breeding efforts.

Adult-onset acute disseminated encephalomyelitis: a rare case report in a 26-year-old female and review of literature.

Acute disseminated encephalomyelitis is a demyelinating autoimmune condition that mostly affects the central nervous system. We present a case of a woman who presented with paralysis and speech deficits following an episode of upper respiratory tract infection. Brain and spinal cord imaging were used to confirm the diagnosis.

Evaluating the knowledge, attitudes, and practices of healthcare workers regarding high-risk nosocomial infections: A global cross-sectional study.

Background: Healthcare workers (HCWs) play a vital role in delivering care and are frequently exposed to the risk of acquiring infections within the hospital setting. Around 15% of hospitalized patients suffer from these infections globally. However, the role and awareness of HCWs in the transmission of hospital-acquired infections (HAIs) or nosocomial infections is still unclear. This study aimed to evaluate the knowledge, attitude, and practices (KAP) toward high-risk microbial infections among HCWs on a global scale to identify measures to address this problem. Method: A cross-sectional descriptive study was conducted between 2022 and 2023, with HCWs selected as the study population. Data concerning KAP were collected through a self-administered online survey questionnaire, using a nonprobability convenience sampling method. Descriptive statistics and regression analysis were used to analyze the data. Results: A total of 743 HCWs from various countries participated in the study, with the majority of respondents being doctors (64.9%). Data were mainly obtained from Saudi Arabia (26.78%), Iraq (25.84%), India (15.7%), the United States of America (15.2%), and Africa (Sudan, Nigeria) (13.98%). The frequency of good KAP scores among physicians (KAP: 82.5, 80.66, and 70.5), nurses (KAP: 74.1, 73.07, and 88.7), medical practitioners (KAP: 87.2, 77.58, and 75.1), and technicians (KAP: 76.1, 74.38, and 89.6) were obtained as mentioned. With respect to experience, HCWs showed good KAP scores in 1-5 years (KAP: 82.4, 83.3, and 74.1), 5-10 years (KAP: 80.6, 74.54, 83), 10-20 years (KAP: 74.7, 79.1, and 82.7), and >20 years (KAP: 84.6, 78.8, and 82.8) categories. Conclusion: This study suggests that HCWs have good KAP regarding infection prevention, but there is still room for improvement. Educational seminars and awareness programs can provide better adherence to barrier protection measures such as hand washing, use of gloves, and hand disinfection.

Unusual cause of chronic abdominal pain in a 17-year-old female: a case report of an epithelial adrenal cyst.

Adrenal cysts are rare lesions that make up 4% of all adrenal masses. They are often found incidentally during imaging or surgery and can vary in symptoms depending on their size and location; with cysts < 10 cm often being asymptomatic. These cysts are more common in adults in their 30s or 60s and can be divided into four histological subtypes, with epithelial cysts being less common. We present a case of a 17-year-old female who experienced recurrent right flank pain for a year. Ultrasonography revealed a cystic mass on the right kidney, and computerized tomography showed a well-defined suprarenal cyst measuring ~8 cm misdiagnosed as mesenteric cyst. However, during laparoscopy, an adrenal cyst was discovered, which was excised along with the right adrenal gland. Histopathology confirmed the diagnosis of an epithelial adrenal cyst. This case highlights the occurrence of adrenal cysts in younger individuals and the uncertainty of preoperative diagnosis.

Remyelination in multiple sclerosis, along with its immunology and association with gut dysbiosis, lifestyle, and environmental factors.

Multiple sclerosis (MS) is a chronic inflammatory disease that damages the myelin sheath around the axons of the central nervous system. While there are periods of inflammation and remyelination in MS, the latter can sometimes be insufficient and lead to the formation of lesions in the brain and spinal cord. Environmental factors such as vitamin D deficiency, viral or bacterial infections, tobacco smoking, and anxiety have been shown to play a role in the development of MS. Dysbiosis, where the composition of the microbiome changes, may also be involved in the pathogenesis of MS by affecting the gut's microbial population and negatively impacting the integrity of the epithelia. While the cause of MS remains unknown, genetic susceptibility, and immunological dysregulation are believed to play a key role in the development of the disease. Further research is needed to fully understand the complex interplay between genetic, environmental, and microbial factors in the pathogenesis of MS.

Effect of dapagliflozin against NAFLD and dyslipidemia in type 2 diabetic albino rats: possible underlying mechanisms.

OBJECTIVE: The aim was to investigate the effect of dapagliflozin on non-alcoholic fatty liver disease and dyslipidemia in type 2 diabetic rats by studying the histopathological structure of the liver and detecting possible underlying mechanisms for this impact by evaluating the potential anti-inflammatory action of dapagliflozin. MATERIALS AND METHODS: 100 albino rats were used in this work and divided into five equal groups: group I (Control group), group II (Control diabetic group), group III (was administered dapagliflozin, 0.75 mg/kg, p.o.), group IV (was administered dapagliflozin, 1.5 mg/kg, p.o.), and group V (was administered dapagliflozin, 3 mg/kg, p.o.). RESULTS: In our study, the total body weight, liver weight, liver index, blood glucose level, insulin level, insulin resistance, total cholesterol, triglycerides, liver enzymes, IL-1 ß, and MDA were significantly higher in the control diabetic group than the normal group. The dapagliflozin reduced all the above variables significantly in a dose-dependent manner compared to the control diabetic group (p-value = 0.001 for all). CONCLUSIONS: Dapagliflozin may be a promising novel treatment strategy for treating T2DM-related non-alcoholic fatty liver disease (NAFLD), and dyslipidemia where it possesses anti-oxidative, anti-inflammatory and anti-dyslipidemic effects.

Perspectives, practices, and challenges of online teaching during COVID-19 pandemic: A multinational survey.

The result of the movement restrictions during the COVID-19 pandemic was an impromptu and abrupt switch from in-person to online teaching. Most focus has been on the perception and experience of students during the process. The aim of this international survey is to assess staffs' perspectives and challenges of online teaching during the COVID-19 lockdown. Cross-sectional research using a validated online survey was carried out in seven countries (Brazil, Saudi Arabia, Jordan, Indonesia, India, the United Kingdom, and Egypt) between the months of December 2021 and August 2022, to explore the status of online teaching among faculty members during the COVID-19 pandemic. Variables and response are presented as percentages while logistic regression was used to assess the factors that predict levels of satisfaction and the challenges associated with online instruction. A total of 721 response were received from mainly male (53%) staffs. Most respondents are from Brazil (59%), hold a Doctorate degree (70%) and have over 10 years of working experience (62%). Although, 67% and 79% have relevant tools and received training for online teaching respectively, 44% report that online teaching required more preparation time than face-to-face. Although 41% of respondents were uncertain about the outcome of online teaching, 49% were satisfied with the process. Also, poor internet bandwidth (51%), inability to track students' engagement (18%) and Lack of technical skills (11.5%) were the three main observed limitations. Having little or no prior experience of online teaching before the COVID-19 pandemic [OR, 1.58 (95% CI, 1.35-1.85)], and not supporting the move to online teaching mode [OR, 0.56 (95% CI,0.48-0.64)] were two main factors independently linked with dissatisfaction with online teaching. While staffs who support the move to online teaching were twice likely to report no barriers [OR, 2.15 (95% CI, 1.61-2.86)]. Although, relevant tools and training were provided to support the move to online teaching during COVID-19 lockdown, barriers such as poor internet bandwidth, inability to track students' engagement and lack of technical skills were main limitations observed internationally by teaching staffs. Addressing these barriers should be the focus of higher education institution in preparation for future disruptions to traditional teaching modes.
