Vedolizumab does not increase risk of clostridium difficile infection in patients with inflammatory bowel disease using vedolizumab: A retrospective cohort study.

Introduction: Several studies have shown increased incidence, recurrence, and severity of Clostridium difficile infection (CDI) over the last decade. Patients with inflammatory bowel disease (IBD) who develop CDI are more prone to morbidity and mortality than CDI in patients without IBD. This study seeks to evaluate whether IBD patients who use vedolizumab are at increased risk of CDI compared to IBD patients using other therapies. Methods: This was a retrospective cohort study, and 684 patients with confirmed IBD (228 on vedolizumab, 228 on anti-TNF, and 228 on 5- Aminosalicylates acid therapy) were enrolled from January 2009 to August 2019 at a tertiary referral IBD center at McMaster University Medical Centre (MUMC) in Hamilton, Ontario, Canada. The primary outcome was time to the development of CDI in IBD patients using different therapies. Secondary outcomes included rates of CDI and the association between baseline variables and risk of CDI. A Cox proportional hazards (PH) model was used to evaluate baseline factors and development of CDI. Result: There was no difference in time to CDI between the three treatment groups (log rank p-value 0.37). CDI occurred in 16 patients (2.3%), specifically four patients (1.75%) in the vedolizumab group, four patients (1.75%) in the anti-TNF group, and eight patients (3.5%) in the 5-ASA group. The Cox PH model found current smoking, older age, and concomitant immunomodulator use as risk factors for CDI, after adjustment for other covariates. Vedolizumab was not associated with increased risk of CDI in the model. Conclusion: Biologic therapy with vedolizumab or anti-TNF did not impact risk of CDI. Risk factors for CDI in IBD patients included smoking, older age at the onset of medication, and immunomodulator therapy. Clinicians should have high degree of suspicion for CDI in IBD patients presenting with diarrhea, particularly in those with risk factors identified in this study.

Oral health status, oral health-related quality of life and personality factors among users of three-sided sonic-powered toothbrush versus conventional manual toothbrush.

OBJECTIVES: This longitudinal within subject controlled randomized observational investigation studied the impacts of three-sided sonic-powered toothbrush versus conventional manual toothbrush on oral health- and oral health-related quality of life (OHRQoL) and assessed the relationship between personality factors and OHRQoL. METHODS: A total of 96 participants (48 females and 48 males; mean age = 22.61 years, SD = 1.21) were recruited into this investigation and were randomly allocated into two groups. The participants were instructed to control oral hygiene for 1 month using either a three-sided sonic brush (Triple Bristle, Dayton, Tennessee, USA) (sonic group) or a conventional manual toothbrush (manual group). Dental plaque was assessed via Turesky-Modified Quigley-Hein Plaque Index (TMQHPI). Bleeding on probing (BOP) was recorded as 1 if present and zero if absent. The NEO Five-Factor Inventory (NEO-FFI) and Oral Health Impact Profile (OHIP-14) were used to assess personality factors and OHRQoL, respectively. TMQHPI, BOP and OHIP were assessed at study baseline and 1 month later. RESULTS: The TMQHPI, BOP and OHIP-14 scores were reduced after 1 month in both groups (p < 0.05), and were more reduced among the three-sided sonic brush users (p > 0.05). Higher neuroticism scores were associated with worse OHRQoL (p < 0.05) in both groups after 1 month. CONCLUSIONS: The three-sided sonic-powered toothbrush was associated with superior oral health and OHRQoL in comparison with the conventional manual toothbrush. Utilizing three-sided sonic toothbrush, less plaque deposits and lower neuroticism scores contributed towards and predicted better OHRQoL after 1 month of oral hygiene maintenance.

Presentation and outcomes of acute appendicitis during COVID-19 pandemic: lessons learned from the Middle East-a multicentre prospective cohort study.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic had a striking impact on healthcare services in the world. The present study aimed to investigate the impact of the COVID-19 pandemic on the presentation management and outcomes of acute appendicitis (AA) in different centers in the Middle East. METHODS: This multicenter cohort study compared the presentation and outcomes of patients with AA who presented during the COVID-19 pandemic in comparison to patients who presented before the onset of the pandemic. Demographic data, clinical presentation, management strategy, and outcomes were prospectively collected and compared. RESULTS: Seven hundred seventy-one patients presented with AA during the COVID pandemic versus 1174 in the pre-COVID period. Delayed and complex presentation of AA was significantly more observed during the pandemic period. Seventy-six percent of patients underwent CT scanning to confirm the diagnosis of AA during the pandemic period, compared to 62.7% in the pre-COVID period. Non-operative management (NOM) was more frequently employed in the pandemic period. Postoperative complications were higher amid the pandemic as compared to before its onset. Reoperation and readmission rates were significantly higher in the COVID period, whereas the negative appendicectomy rate was significantly lower in the pandemic period (p = 0.0001). CONCLUSION: During the COVID-19 pandemic, a remarkable decrease in the number of patients with AA was seen along with a higher incidence of complex AA, greater use of CT scanning, and more application of NOM. The rates of postoperative complications, reoperation, and readmission were significantly higher during the COVID period.

Molecular autopsy by proxy in preconception counseling.

Monogenic diseases that result in early pregnancy loss or neonatal death are genetically and phenotypically highly variable. This often poses significant challenges in arriving at a molecular diagnosis for reproductive planning. Molecular autopsy by proxy (MABP) refers to the genetic testing of relatives of deceased individuals to deduce the cause of death. Here, we specifically tested couples who lost one or more children/pregnancies with no available DNA. We developed our testing strategy using whole exome sequencing data from 83 consanguineous Saudi couples. We detected the shared carrier state of 50 pathogenic variants/likely pathogenic variants in 43 families and of 28 variants of uncertain significance in 24 families. Negative results were seen in 16 couples after variant reclassification. In 10 families, the risk of more than one genetic disease was documented. Secondary findings were seen in 10 families: either genetic variants with potential clinical consequences for the tested individual or a female carrier for X-linked conditions. This couple-based approach has enabled molecularly informed genetic counseling for 52% (43/83 families). Given the predominance of autosomal recessive causes of pregnancy and child death in consanguineous populations, MABP can be a helpful approach to consanguineous couples who seek counseling but lack molecular data on their deceased offspring.

COVID-19 and cardiovascular system-a comprehensive review.

Coronavirus disease 2019 (COVID-19), a mystified cryptic virus has challenged the mankind that has brought life to a standstill. Catastrophic loss of life, perplexed healthcare system and the downfall of global economy are some of the outcomes of this pandemic. Humans are raging a war with an unknown enemy. Infections, irrespective of age and gender, and more so in comorbidities are escalating at an alarming rate. Cardiovascular diseases, are the leading cause of death globally with an estimate of 31% of deaths worldwide out of which nearly 85% are due to heart attacks and stroke. Theoretically and practically, researchers have observed that persons with pre-existing cardiovascular conditions are comparatively more vulnerable to the COVID-19 infection. Moreover, they have studied the data between less severe and more severe cases, survivors and non survivors, intensive care unit (ICU) patients and non ICU patients, to analyse the relationship and the influence of COVID-19 on cardiovascular health of an individual, further the risk of susceptibility to submit to the virus. This review aims to provide a comprehensive particular on the possible effects, either direct or indirect, of COVID-19 on the cardiovascular heath of an individual.

Mechanistic insights into the pathogenesis of neurodegenerative diseases: towards the development of effective therapy.

Neurodegeneration is a prevalent and one of the emerging reasons for morbidity, mortality, and cognitive impairment in aging. Dementia is one of such conditions of neurodegeneration, partially manageable, irreversible, and worsens over time. This review is focused on biological and psychosocial risk factors associated with Alzheimer's and Parkinson's diseases, highlighting the value of cognitive decline. We further emphasized on current therapeutic strategies from pharmacological and non-pharmacological perspectives focusing on their effects on cognitive impairment, protein aggregation, tau pathology, and improving the quality of life. Deeper mechanistic insights into the multifactorial neurodegeneration could offer the design and development of promising diagnostic and therapeutic strategies.

Increased mRNA expression of key cytokines among suspected cases of Pneumocystis jirovecii infection.

BACKGROUND: Pneumocystis pneumonia (PCP) is a fatal infectious disease caused by Pneumocystis jirovecii (PJP). The major factor relevant to morbidity and mortality seems to be the host inflammatory reaction. The objective of this study was to evaluate the role of IL-2, IL-4, IL-10, and IL-13 cytokine mRNA expression among suspected P. jirovecii infection. METHODS: This was a cross-sectional analytical study undertaken in Aseer region, Saudi Arabia. One hundred suspected PCP cases and 100 healthy controls were included in the study. Basic clinical manifestations, radiological findings, microbiological and immunological findings were extracted from the hospital records from January 2019 to August 2019, Pneumocystis detection was done by immune-fluorescent staining (IFAT, Gomorimethanamine silver staining (GMSS), Giemsa staining, Toluidine blue O (TBO), and Pneumocystis RT-PCR. RESULTS: Increased more than 5 fold, 3 fold, 4 fold, and 7 fold of IL-2, IL-4, IL-10, and IL-13 mRNA expression were observed in PCP cases compared to controls. Higher expression of IL-2 mRNA was connected with crept, wheezing and chest X-ray findings like central perihilar infiltrate, patchy infiltrate, consolidation, hilar lymphadenopathy, pneumothorax, pleural effusion which showed higher expression compared to counterpart (p< 0.0001). Higher expression of IL-4 mRNA was found to be significantly associated with weight loss (p=0.002), dyspnea (p=0.003), crept (p=0.01), and chest X-ray findings (p< 0.0001). Significantly increased expression of IL-10 mRNA was observed to be associated with weight loss, dyspnea, night sweats, wheezing, and different findings of chest X-ray compared to their counterparts, whereas, IL-13 mRNA was observed in cases with fever. Suspected cases of PCP confirmed positive by IFTA with higher IL-2, IL-4, and IL-10 mRNA expression compared to negative cases. RT-PCR confirmed PCP cases had significantly higher expression of IL-2, IL-4, and IL-10 as well as IL-13 mRNA compared to negative cases. Positive detected cases by GMSS showed higher IL-2, IL-10 mRNA expression, while Giemsa showed only higher IL-4 mRNA expression compared to negative cases. CONCLUSION: Confirmed cases of P. jirovecii showed higher IL-2, IL-4, IL-10, and IL-13 mRNA expression comparatively to negative cases. Increased expression of cytokines may be indicative of infection severity and could help in patients' management.

Evaluation of cephalometric lip morphology in a Saudi sub population: A cross sectional study.

This cross-sectional study was done to evaluate linear and angular measurement of lip morphology in Saudi adults and their comparison with the norms. After taking their history and physical examination, the patients were referred for a lateral Cephalograph using Dolphin Imaging Software. Linear and angular measurements related to lip morphology were recorded. Significant differences were found in the lower lip to E line, upper and lower lip protrusion, upper and lower lip to S line and upper and lower lip thickness, nasolabial angle, Z angle, with Saudi males having more prominent, thicker lips than the Saudi females. Comparison with the norms revealed that both lips are prominent among Saudi males, while in females there is an increased prominence of the lower lip. Value of the lower lip to H line is increased in both genders, males have prominent and thicker upper lips compared to the females and the lower lip in both genders is more prominent compared to the norms.

Patient-Reported Outcomes and Endoscopic Appearance of Ulcerative Colitis: A Systematic Review and Meta-analysis.

BACKGROUND & AIMS: We aimed to evaluate the association of the patient-reported outcomes for rectal bleeding and stool frequency among patients with ulcerative colitis (UC) in endoscopic remission. METHODS: We performed a systematic review of studies reporting the association of patient-reported outcomes (the patient-reported components of the Mayo score: rectal bleeding and stool frequency) and endoscopic remission (Mayo endoscopic subscore of 0 or 1). We performed a meta-analysis of diagnostic accuracy using the hierarchical bivariate method. RESULTS: Our meta-analysis consisted of 5 studies comprising 2132 participants. A rectal bleeding subscore of 0 identified patients in endoscopic remission with a pooled sensitivity value of 81% (95% CI, 73%-86%), a specificity value of 68% (95% CI, 61%-75%), a positive likelihood ratio (LR) of 2.5 (95% CI, 2.2-3.0), and a negative LR of 0.28 (95% CI, 0.22-0.37). A stool frequency subscore of 0 identified patients in endoscopic remission with a pooled sensitivity value of 40% (95% CI, 25%-58%), a specificity value of 93% (95% CI, 86%-97%), a positive LR of 6.0 (95% CI, 3.7-9.7), and negative LR of 0.64 (95% CI, 0.50-0.82). A combined rectal bleeding and stool frequency subscore of 0 identified patients in endoscopic remission with a pooled sensitivity value of 36% (95% CI, 22%-54%), a specificity value of 96% (95% CI, 91%-98%), a positive LR or 8.4 (95% CI, 5.5-12.8), and a negative LR or 0.66 (95% CI, 0.53-0.84). CONCLUSIONS: In a meta-analysis of 5 studies, we found that most patients with UC and normal rectal bleeding and stool frequency subscores have attained endoscopic remission. Many patients in endoscopic remission from UC have no rectal bleeding. Normal stool frequency associates with endoscopic remission, but many patients have abnormal stool frequencies despite endoscopic remission. These results should be carefully considered given the high heterogeneity and wide confidence intervals for some outcomes.

A new predictive scoring model for globus pharyngeus in patients with gastroesophageal reflux disease.

BACKGROUND: Globus pharyngeus is a clinical condition, wherein, a patient senses a lump or a foreign body in the throat with a tightening or choking feeling. A strong association between globus pharyngeus and gastroesophageal reflux disease (GERD) was reported. Therefore, we sought to investigate the predictive factors of globus pharyngeus in patients with established GERD and fit a predictive scoring model for globus pharyngeus. METHODS: In this case-control study, 143 patients having globus pharyngeus along with GERD ( case ) and 109 patients having globus pharyngeus without GERD ( control ) were enrolled. Data comprising demographics, comorbidities, and psychosocial stress levels were recorded. The predictive factors of globus pharyngeus in patients with GERD were unraveled, and a predictive scoring model was fit for globus pharyngeus. RESULTS: Proton pump inhibitor usage in the case group was significantly higher compared to controls (63.63% vs 24.78%, P < 0.001), and differences in Hiatus Hernia and Stress levels were highly significant between the two groups ( P < 0.001). Multivariate logistic regression revealed that variates, Hiatus Hernia, psychosocial stress, and age were highly significant ( P < 0.001) independent predictors of globus pharyngeus. Using the regression coefficients of all the independent predictor variables, a predictive scoring model was fitted, which yielded an area under receiver operating characteristic (AUROC) curve of 78.9. CONCLUSION: Hiatus hernia, psychosocial stress, and age are significant independent predictors of globus pharyngeus in GERD, and our predictive scoring model may help in identifying patients at higher odds of experiencing globus pharyngeus and modulate treatment accordingly.

Pituitary Apoplexy After a Major Abdominal Surgery: A Case Report.

Pituitary apoplexy is a major complication of pituitary adenoma, and the diagnosis might be challenging if the patient presents with signs of meningeal irritation or electrolyte imbalance. It can be fatal if not diagnosed and treated appropriately. Apoplexy is the first clinical presentation in the majority of pituitary adenoma cases. The pathophysiology of pituitary apoplexy involves bleeding and/or ischemia of pituitary enlargement. In this case report, we present a case of pituitary apoplexy that developed after a major abdominal surgery. The patient presented with headache, hypertension, and visual loss. After confirming the diagnosis through a CT scan, the patient underwent a transsphenoidal surgical decompression.

Current speed sintering and high-speed sintering protocols compromise the translucency but not strength of yttria-stabilized zirconia.

OBJECTIVES: To investigate the impacts of speed and high-speed sintering on the densification, microstructure, phase composition, translucency, and flexural strength of yttria-stabilized zirconia (YSZ). METHODS: A total of 162 disc-shaped specimens (n = 18) were cold-isostatically pressed from 3YSZ (Zpex), 4YSZ (Zpex 4), and 5YSZ (Zpex Smile) powders (Tosoh Corporation) and sintered according to the following protocols: conventional (control, ∼12 h), speed (∼28 min for 3YSZ; ∼60 min for 4YSZ and 5YSZ), and high-speed (∼18 min) sintering. Dimensions of zirconia specimens after sintering and polishing (1-µm diamond grit finish) were Ø13.75 × 1 mm. Density, microstructure, phase content, translucency parameter, and biaxial flexural strength were evaluated using Archimedes', SEM, XRD, spectrophotometric, and piston-on-3-ball methods, respectively. Data were analyzed with either one-way ANOVA and Tukey's test or Kruskal-Wallis with Dunn's test (α = 0.05). RESULTS: For all YSZ compositions, conventional sintering yielded the highest density followed by speed then high-speed sintering. All sintering protocols resulted in similar strength values; however, speed and high-speed sintering protocols afforded significantly lower translucency relative to conventional sintering. XRD analysis revealed similar spectra for YSZs sintered by various protocols. The speed sintered specimens had the smallest grain size whereas the high-speed sintered 5YSZ possessed the largest grain size among all groups. SEM examination of all YSZ compositions revealed that the average pore size was an order of magnitude smaller than the average grain size. SIGNIFICANCE: Speed and high-speed sintering of YSZs yield similar strength but diminished density and translucency relative to their conventionally sintered counterparts.

Association of esophageal motility disorder symptoms with Chicago classification versions 3.0 and 4.0 using high-resolution esophageal manometry: A single-center experience from Saudi Arabia.

BACKGROUND: Esophageal motility disorders (EMDs) can significantly impact patients' quality of life. The Chicago Classification (CC) was developed as a robust framework to enable clinicians to better understand and classify the nature of motility disorders. Previous studies have primarily focused on the CC version 3.0 (CCv3.0), and data regarding the correlation between symptoms and CC version 4.0 (CCv4.0) in the Saudi Arabian population are lacking. This study aimed to assess the correlation between symptoms and CCv3.0 and CCv4.0 using high-resolution esophageal manometry (HRM) in Saudi Arabia, to evaluate the diagnostic performance of both classifications. METHODS: A total of 182 patients presenting with esophageal symptoms were included in this study. HRM was performed to assess esophageal motility, and patients' reported symptoms were recorded. The association between HRM findings and symptomatic variables was analyzed using sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). RESULTS: Variability was observed in the diagnostic performance of symptomatic variables for major EMDs. CCv4.0 demonstrated a higher sensitivity for dysphagia than CCv3.0; however, it exhibited lower sensitivity to atypical gastroesophageal reflux disease (GERD) symptoms. Noncardiac chest pain (NCCP) exhibited the highest specificity and PPV, whereas typical GERD symptoms showed lower specificity. CONCLUSION: CCv4.0 demonstrated potential improvements in sensitivity for dysphagia, but lower sensitivity for atypical GERD symptoms, compared with CCv3.0. These insights provide guidance for clinicians in Saudi Arabia and contribute to understanding the diagnostic performance of CCv3.0 and CCv4.0.

Transient thermal stresses developed during speed sintering of 3 mol% yttria-stabilized tetragonal zirconia polycrystals.

OBJECTIVES: To investigate transient thermal stresses that developed in 3Y-TZP green compacts during speed sintering. METHODS: A total of 312 disc-shaped green compacts (Ø17.1 ×1, 1.5, 2, 2.5, 3 mm) were cold-isostatically pressed from 3Y-TZP powder (Zpex, Tosoh Corp.) for speed sintering studies as well as compositional analysis and biaxial flexural strength measurements (both at room temperature and following heating at 90 °C/min to 500 °C). Flexural strength was determined using the piston-on-3-ball method. Phase assemblies were analyzed using the X-ray diffraction method. Effects of heating/cooling rates on transient stresses were investigated by conducting definitive sintering studies to determine the threshold for fracture. Finite element analysis (FEA) was used to validate the experimental findings using measured thermomechanical properties. RESULTS: The bulk and relative density of the green compact were 2.95 ± 0.03 g/cm3 and 48.52% ± 0.45%. The flexural strength was drastically decreased from 10.3 ± 0.4 MPa to 1.09 ± 0.07 MPa following heating at 90 °C/min to 500 °C. The monoclinic and tetragonal contents were 54.9% and 45.1%, respectively. The threshold for fracture was located at 500 °C during the first heating stage with a 90 °C/min heating rate in specimens of 2.5 mm thickness or greater. No fractures occurred in the second heating stage and cooling phase. The FEA estimated that the principal transient tensile stress was ∼1.14 MPa at 500 °C during the heating phase, which exceeded the corresponding flexural strength (1.09 ± 0.07 MPa). SIGNIFICANCE: Advanced FEA methods are an accurate and efficient tool to analyze the history of transient stresses during sintering of ceramic dental restorations.

Practice guidelines for the management of Helicobacter pylori infection: The Saudi H. pylori Working Group recommendations.

The eradication rates for Helicobacter pylori globally are decreasing with a dramatic increase in the prevalence of antibiotic resistant bacteria all over the world, including Saudi Arabia. There is no current consensus on the management of H. pylori in Saudi Arabia. The Saudi Gastroenterology Association developed these practice guidelines after reviewing the local and regional studies on the management of H. pylori. The aim was to establish recommendations to guide healthcare providers in managing H. pylori in Saudi Arabia. Experts in the areas of H. pylori management and microbiology were invited to write these guidelines. A literature search was performed, and all authors participated in writing and reviewing the guidelines. In addition, international guidelines and consensus reports were reviewed to bridge the gap in knowledge when local and regional data were unavailable. There is limited local data on treatment of H. pylori. The rate of clarithromycin and metronidazole resistance is high; therefore, standard triple therapy for 10-14 days is no longer recommended in the treatment of H. pylori unless antimicrobial susceptibility testing was performed. Based on the available data, bismuth quadruple therapy for 10-14 days is considered the best first-line and second-line therapy. Culture and antimicrobial susceptibility testing should be considered following two treatment failures. These recommendations are intended to provide the most relevant evidence-based guidelines for the management of H. pylori infection in Saudi Arabia. The working group recommends further studies to explore more therapeutic options to eradicate H. pylori.

Characteristics of Children with Cerebral Palsy and Their Utilization of Services in Saudi Arabia.

The recent emergence of research on cerebral palsy (CP) in developing countries aims to improve knowledge on affected children and the utilization of the available services. This study seeks to describe children with CP in Saudi Arabia and service utilization as per Gross Motor Function Classification System (GMFCS) levels and geographic regions. A cross-sectional survey of 227 children with CP (Mean age 6.3, SD 3.9 years) was conducted. Parents reported on children's demographics, impairments, and service utilization. Half of the children (n = 113, 49.8%) had ≥3 impairments with speech, visual and learning impairments being the most frequent. The total number of impairments differed significantly by GMFCS, F (4, 218) = 8.87, p < 0.001. Most of the children (n = 86, 83.4%) used 2-5 services. Moreover, 139 (62.3%) did not attend school, 147 (65.9%) did not receive occupational therapy, and only 32 (14.3%) received speech therapy. More children in GMFCS level I did not receive neurologist services. Profiles of children and services were described by GMFCS and by regions. This was the first study to describe children with CP and service utilization in Saudi Arabia. Although many impairments affected the children, there was low utilization of related services. Data on service utilization and on unmet needs support a comprehensive approach to rehabilitation and the proper service allocation.

Assessing the relationship between burnout syndrome and irritable bowel syndrome among medical health providers and medical students in Saudi Arabia.

Burnout syndrome, characterized by chronic unmanageable workplace stress, has been linked to lower gastrointestinal disorders, including irritable bowel syndrome. However, the relationship between burnout syndrome and irritable bowel syndrome among medical health providers and medical students in Saudi Arabia has not been fully explored. This cross-sectional correlational study was conducted in Southern Saudi Arabia from 2021 to 2022 and involved 931 medical health providers and medical students who completed an electronic questionnaire. The study assessed the presence and severity of burnout and irritable bowel syndrome and examined their relationship. Burnout syndrome was evaluated using the Maslach Burnout Inventory-Student Survey (MBI-SS), while irritable bowel syndrome criteria and severity were assessed using validated tools. The study found that 85% of medical health providers and medical students experienced high levels of burnout and irritable bowel syndrome severity, with physicians and nurses mainly affected. Occupational exhaustion was high in 44.4% of participants, while depersonalization was high in 53% of participants. Personal accomplishment was low in 73.5% of participants. Mild, moderate, and severe irritable bowel syndrome was reported in 25.6%, 23.8%, and 12% of participants, respectively. The study highlights a significant association between burnout syndrome and irritable bowel syndrome severity among medical health providers and medical students in Saudi Arabia. These findings underscore the importance of developing effective interventions to prevent and manage burnout syndrome and related health issues among healthcare professionals and medical students in the region.

Cross-Sectional Assessment of Dermatologists' Knowledge and Attitude Towards Isotretinoin-Related Ocular Side Effects in Aseer, Saudi Arabia.

BACKGROUND: Acne vulgaris is a chronic inflammatory disease of the pilosebaceous unit, which includes the hair follicle, hair shaft and sebaceous gland. The only treatment that has an effect on all the main aetiological causes of acne is isotretinoin. However, it may have a variety of negative side effects. The aim of this study was to evaluate the knowledge and attitudes of dermatologists regarding ocular effects following isotretinoin prescribing in the Aseer region, Saudi Arabia. METHODOLOGY: An anonymous online cross-sectional survey was conducted in August 2022 to investigate dermatologists' knowledge and attitude regarding isotretinoin-related ocular side effects in Aseer, Saudi Arabia. Participants were recruited using convenience and snowball sampling methods. RESULTS: A total of 48 dermatologists were included in this survey. The age distribution ranged from 25 to over 60 years. Sixteen (37.5%) were aged 31-40 years, 29 (60.4%) were male and 20 (41.7%) were specialists. All dermatologists reported that it can cause dry eye, 32 (66.7%) reported that it can cause contact lens intolerance, 10 (20.8%) reported that it can cause a decrease in dark adaptation and two (4.2%) thought that it can cause ectopia lentis and retinoblastoma. Regarding attitude, 43 (87.5%) thought that a course of isotretinoin is not recommended if the patient has recently undergone refractive surgery, 30 (62.5%) always inform patients about ocular side effects, 31 (72.9%) do not consider referring patients for ophthalmic examinations before initiating isotretinoin, 12 (25.0%) always prescribe lubricant eye drops, 15 (31.3%) always ask patients about recent refractive surgery, 17 (35.4%) always warn patients about avoiding refractive surgery during isotretinoin use and 19 (39.6%) always inform patients concerning discomfort with contact lenses. CONCLUSIONS: The survey reveals that dermatologists in Aseer, Saudi Arabia, generally have good knowledge of isotretinoin related to some ocular side effects, especially dry eye and contact lens intolerance. However, there is some variation in their practices with regard to patient education, referrals for ophthalmic examinations, the use of lubricant eye drops and refractive surgery during isotretinoin treatment. Thus, dermatologists should receive educational training on the safety profile of isotretinoin while managing acne vulgaris.

Knowledge, Attitude, and Practices of Schoolteachers Toward Epilepsy and Students With Epilepsy in the Aseer Region.

BACKGROUND: The knowledge that teachers have about epilepsy affects their attitudes and practices towards students with the disorder. This study aimed to explore teachers' knowledge, attitudes, and practices (KAP) toward epilepsy in the Aseer region. METHODS: This online cross-sectional survey targeted teachers aged 18 years and above, encompassing both males and females residing in the Aseer region with internet access. Teachers included in this study were recruited using snowball and convenience non-random sampling methods. Descriptive statistics and Pearson's chi-square test in Statistical Package for the Social Sciences (SPSS) version 27 were employed, with a significance level of 0.05 (IBM Corp., Armonk, NY). RESULTS: A total of 62 teachers were included in this study: 62.90% were aged 35-49, 93.55% were females, 90.32% were married, 80.65% worked in the governmental sector, 51.61% earned between 5,000 and 10,000 SAR, and 93.55% held a university education. Regarding knowledge, 36.6% of the teachers studied had very bad knowledge, 29% had poor knowledge, 35.5% had intermediate knowledge, and 4.8% had good knowledge. While 1.9% had a detrimental attitude about epilepsy, 58.1% had an incorrect attitude, 30.6% had an approximate attitude, and 1.6% had a correct attitude. Concerning teacher practice, 4.8% of the studied sample had detrimental practice, 56.5% had inadequate practice, and 4.8% had average practice. CONCLUSIONS: The study highlights the need for targeted educational interventions to improve teachers' knowledge about epilepsy. The positive attitudes observed provide a foundation for fostering inclusivity in educational settings. Strategies that address misconceptions and improve first aid preparedness can contribute to a more supportive environment for students with epilepsy.

Risk and diagnostic factors and therapy outcome of neonatal early onset sepsis in ICU patients of Saudi Arabia: a systematic review and meta analysis.

Background: Neonatal early onset sepsis (NEOS) is a serious and potentially life-threatening condition affecting newborns within the first few days of life. While the diagnosis of NEOS was based on clinical signs and symptoms in the past, recent years have seen growing interest in identifying specific diagnostic factors and optimizing therapy outcomes. This study aims to investigate the diagnostic and risk factors and therapy outcomes of neonatal EOS in ICU patients in Saudi Arabia, with the goal of improving the management of neonatal EOS in the country. Methods: This method outlines the protocol development, search strategy, study selection, and data collection process for a systematic review on neonatal early onset sepsis in Saudi Arabian ICU patients, following the PRISMA 2020 guidelines. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is a well-established guideline that provides a framework for conducting systematic reviews and meta-analyses in a transparent and standardized manner. It aims to improve the quality and reporting of such research by ensuring clear and comprehensive reporting of study methods, results, and interpretations. The search strategy included electronic databases (PubMed, Embase, Google Scholar, Science Direct, and the Cochrane Library) and manual search of relevant studies, and data were extracted using a standardized form. Results: The systematic review included 21 studies on neonatal sepsis in Saudi Arabia, with varying study designs, sample sizes, and prevalence rates of sepsis. Group B streptococcus and E. coli were the most commonly isolated pathogens. Various diagnostic factors and risk factors were reported, including hematological parameters, biomarkers, and blood cultures. The quality of the included studies was assessed using the Newcastle-Ottawa Scale and Joanna Briggs Institute critical checklist. Conclusions: The review identified a number of risk and diagnostic factors and therapy outcomes for neonatal sepsis. However, most of the studies were having small scale cohort groups. Further research with controlled study designs is needed to develop effective prevention and management strategies for neonatal sepsis in Saudi Arabia.
