Effect of Air Pollutants Particulate Matter PM2.5, PM10, Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), and Ozone (O3) on Fractional Exhaled Nitric Oxide (FeNO).

Objectives: This study aimed to investigate the effect of Environmental Pollutants Particulate Matter PM2.5, PM10, Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), and Ozone (O3) on lung airway inflammation by assessing the Fractional Exhaled Nitric Oxide (FeNO) in students studying in schools located in or away from air-polluted areas. Methods: This matched case-control cross-sectional study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia from August 2022 to July 2023. In this study, two schools were selected, one was located near a traffic-polluted area (School #1), and the second was located away from the traffic-polluted area (School #2). A total of 300 students were recruited, 150 (75 male and 75 female) students from the school located in a traffic-polluted area, and 150 students (75 male and 75 female) from the school located away from a traffic-polluted area. Environmental pollutants PM2.5, PM10, CO, NO2, O3, and SO2, were recorded. The Fractional Exhaled Nitric Oxide (FeNO) was measured using a Niox Mino. Results: The mean concentration of PM2.5, PM10, CO, NO2, O3, and SO2 were 35.00±0.65 significantly higher in a school located in motor vehicle polluted area compared to a school located away from a motor vehicle-polluted area (29.95±0.32) (p=0.001). The mean values for FeNO were significantly higher (18.75±0.90) among students studying in a school located in the motor vehicle-polluted area compared to students studying in a school located away from the motor vehicle-polluted area (11.26±0.56) (p=0.001). Conclusions: Environmental pollution can cause lung inflammation among students in schools located in traffic-polluted areas.

An unexpected opportunist: Magnusiomyces capitatus infection in an immunocompetent patient.

Magnusiomyces capitatus is an uncommon opportunistic fungal pathogen primarily affecting immunocompromised individuals. While rare, cases have been reported in immunocompetent patients. We present a documented case of Magnusiomyces capitatus invasive infection in an immunocompetent patient with no previous medical history. This case shows that invasive fungal infections by Magnusiomyces capitatus might affect even the immunocompetent patients.

Development and validation of impact of early integration of palliative care and oncology(IEI PCO) questionnaire: a survey for medical oncologists and nurses.

OBJECTIVES: Many associations have recently recommended early integration of oncology and palliative care for more standard cancer care and better quality of life. We aimed to create a questionnaire to assess the opinion of medical oncologists and nurses about the clinical impact of the integrated palliative care and oncology (PCO) program. METHODS: A novel semi-structured questionnaire called Impact of Early Integration of Palliative Care Oncology (IEI PCO) questionnaire was developed and tested for validity and reliability then distributed to the oncologists and nurses working in Kuwait Cancer Control Center. RESULTS: After the pilot stage, testing the final questionnaire for validity and reliability was done with satisfactory results. Finally, the complete questionnaires were 170 out of 256 (response rate 66.41%). More awareness about the available palliative care services and the new available PCO services (p-value < 0.001 for all). Most of the oncologists and nurses agreed with the currently available structure of PCO, appreciated the patients' discharge plan and continuity of care of palliative medicine, admitted less work burden, a better attitude, and higher satisfaction (p-value for all < 0.001) toward palliative care. Significant improvements in symptoms were appreciated by oncologists and nurses after the integration of palliative care (p-value for all < 0.001. Oncologists and nurses valued repeated honest communication, discussion of the goals of care, dealing more effectively with ending active treatment, and higher acceptance of patients and families of PC policy of transfer, and significant progress in the care of end-of-life symptoms (p-value for all < 0.001). CONCLUSIONS: The IEI PCO questionnaire demonstrated the psychometric criteria for content, face, and construct validity and reliability. It provides a valuable tool to assess the impact of PCO integration. The opinion of medical oncologists and nurses was significantly positive toward the early integration of PCO in Kuwait in most aspects of care. This integration led to improved symptom control, end-of-life care, communication, and planned discharge and follow-up plans. Moreover, decreases the work burden, improves attitude, higher satisfaction of the oncology staff, and continuity of care.

The Saudi consensus recommendations for the management of psoriatic arthritis (2023).

Psoriatic arthritis (PsA) is a complex inflammatory disease characterized by musculoskeletal and non-musculoskeletal manifestations. It is a distinct disease entity at the interface between rheumatology and dermatology, making it challenging to manage. The diverse clinical presentation and severity of PsA require a multidisciplinary approach for optimal care. Early diagnosis and management are necessary to improving quality of life for patients. In Saudi Arabia, there is currently no unified national consensus on the best practices for managing PsA. This lack of consensus leads to debate and uncertainty in the treatment of the disease, resulting in over or under prescribing of biological agents. To address this issue, a multidisciplinary work group was formed by the Saudi Ministry of Health. This group, consisting of dermatologists, rheumatologists, and pharmacists, aimed to develop evidence-based consensus recommendations for he use and monitoring of biological therapy in PsA management. The work group conducted five consensus workshops between December 2021 to March 2022. Using the nominal group technique, they discussed various aspects of PsA management, including eligibility criteria for biological treatment, monitoring of disease activity, treatment goals, screening, precautions, and management of PsA with biologic therapies. The group also considered special considerations for patients with comorbidities, pregnant and lactating women, as well as pediatric and adolescent populations. The resulting consensus document provides recommendations that are applicable to the Saudi setting, taking into account international guidelines and the specific needs of PsA patients in the country. The consensus document will be regularly updated to incorporate new data and therapeutic agents as they become available. Key Points • In Saudi Arabia, there is a lack of unified national consensus on the optimal management of PsA, therefore, this article aims to provide up-to-date evidence-based consensus recommendations for the optimal use and monitoring of biologic therapy in the management of PsA in Saudi Arabia. • The consensus development process was undertaken by a multidisciplinary work group of 13 experts, including two dermatologists, six rheumatologists, and five pharmacists. • There is more than one disease activity tool used in PsA disease, depending on the disease domain - peripheral arthritis Disease Activity Index in Psoriatic Arthritis (DAPSA) or Minimal Disease Activity (MDA), axial PsA Ankylosing Spondylitis Disease Activity Score (ASDAS), and dactylitis and enthesitis MDA. • The main goal of therapy in all patients with PsA is to achieve the target of remission, or alternatively, low disease activity in all disease domains and improve quality of life (QoL).

Cardiac Surgery Morbidity and Mortality in Hypertensive and Arrhythmic Patients: A Retrospective Analysis.

BACKGROUND: Hypertension (HTN) is the most significant modifiable risk factor for cardiovascular disease (CVD) and overall mortality. HTN is defined as a systolic blood pressure of ≥140 mmHg and/or a diastolic blood pressure of ≥ 90 mmHg. Generally, arrhythmias are characterized by a disruption of the heart's regular rhythm. They are strongly associated with increased risks of CVDs and sudden death. The most common arrhythmia worldwide is atrial fibrillation (AF). HTN, diabetes mellitus (DM), and coronary artery disease (CAD) are major risk factors for arrhythmias. OBJECTIVE: We aimed to identify the postoperative effects and risk factors of HTN and cardiac arrhythmia in patients who underwent cardiac surgery at King Abdulaziz University Hospital (KAUH) from 2015 to 2022. METHODS: A retrospective record review was conducted by collecting data from KAUH electronic medical records. A total of 402 patients participated in this study. This study includes all hypertensive and arrhythmic patients who underwent cardiac surgeries. RESULTS: Of the 402 patients studied, 209 had pre-operative HTN, and 47 had preoperative AF. Developing post-operative arrhythmia was found to significantly increase perioperative morbidity and mortality (p < 0.001). Risk factors for HTN and arrhythmia included increased age, higher BMI, and DM. CONCLUSION: The findings of this study suggest an association between preoperative HTN and AF and elevated rates of postoperative morbidity and mortality. AF emerged as the predominant arrhythmia type. It is advisable to optimize patients' health status prior to surgical procedures. Moreover, further research is recommended in this field to deepen our understanding of the perioperative implications of HTN and arrhythmias.

Association of the Academic Performance of Undergraduate Medical Students With Positive Well-Being, Intelligence, and Factors of Academic Success.

BACKGROUND: The academic performance of medical students may affect their competence in future career prospects. Developing students' subjective well-being to improve academic performance is complex and has been investigated for many years. This cross-sectional study assessed the relationship between academic performance, general intelligence, and medical students' positive well-being. METHODS: This cross-sectional, internet-based survey included male and female medical students from pre-clinical and clinical years at one of the largest public-sector universities in Riyadh, Saudi Arabia, between February 2020 and April 2020. The questionnaire included the World Health Organization-Five (WHO-5) Well-being Index, the Draw-A-Person Intellectual Ability (DAP: IQ) Test, and the Academic Success Inventory for College Students (ASICS). Academic performance was represented by a self-reported high-grade point average (GPA). Logistic regression was used to assess the association between academic performance and each of the well-being scores, intelligence, and academic success factors. Statistical significance was established at a p-value less than 0.05. RESULTS: Responses were received from 176 medical students. Most participants were males (93.8%). There was a significant association between GPA above 4.5 and the total WHO-5 well-being score (p = 0.013), the ASICS general skills (p = 0.007), perceiving instructor efficacy (p = 0.005), confidence (p < 0.001), personal adjustment (p = 0.023), and lack of anxiety (p = 0.006). No association was found between GPA and intelligence quotient (IQ) or well-being when other factors were adjusted. CONCLUSIONS: Good academic performance is associated with subjective well-being and domains of academic success, such as perceived efficacy of the instructor, confidence, and personal adjustment. Implementing student development programs in medical schools can have a positive impact on students' academic performance and skills. Future studies assessing the different student support and development programs and their impact on academic success are needed.

Comparative effectiveness and cost evaluation of Risankizumab and Adalimumab in the management of psoriasis: a real-world study in Saudi Arabia.

BACKGROUND: Psoriasis, an immune-mediated chronic inflammatory disease primarily affecting skin and joints, has varying prevalence rates globally. It manifests in five types, with chronic plaque psoriasis being the most common. Treatment, which has no definitive cure, aims for complete resolution of skin symptoms and depends on disease extent, severity, and impact on patients' lives. Biologics are an emerging treatment for psoriasis, targeting specific inflammatory pathways for potentially safer, more effective outcomes. However, these come with significant costs, necessitating more research to ensure value for money. This study aimed to compare the effectiveness of Risankizumab versus Adalimumab, the most commonly utilized biologic for managing psoriasis in Saudi Arabia. METHODS: This study retrospectively compared the effectiveness and direct medical cost of Risankizumab and Adalimumab in treating chronic plaque psoriasis in adults from two Saudi Arabian healthcare centers. The Psoriasis Area and Severity Index (PASI) and body surface area (BSA) were used to assess treatment effectiveness, with patient data sourced from electronic medical records. Multiple regression analysis was performed to examine various factors affecting treatment outcomes. An economic evaluation was conducted to examine the cost-effectiveness of the two drugs, considering four scenarios with varying dosage patterns and costs. Analysis was performed from the perspective of public healthcare payers and considered all utilized health services. RESULTS: The data for 70 patients were analyzed, with comparable baseline characteristics between groups. While Risankizumab led to a greater reduction in PASI scores and BSA affected, these results were not statistically significant. The annual treatment cost for Risankizumab was higher than Adalimumab. Various scenarios were studied, considering real acquisition costs, double dosing for Adalimumab, and the use of biosimilars. A scenario assuming double dosing for Adalimumab and a 40% discount for Risankizumab demonstrated both cost and efficacy advantages in 71.25% of cases. CONCLUSIONS: This study compared the effectiveness and cost of Risankizumab and Adalimumab for treating chronic plaque psoriasis in Saudi Arabian hospitals. Although Risankizumab showed a greater reduction in symptoms, the difference was not statistically significant. However, under certain scenarios, Risankizumab demonstrated cost and efficacy advantages. These findings may influence treatment decisions for psoriasis, but further research is needed.

Tirzepatide-Induced Gastrointestinal Manifestations: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis determine how frequently and how seriously gastrointestinal manifestations affect people with type 2 diabetes mellitus on tirzepatide. Tirzepatide is a recently developed drug that attempts to enhance type 2 diabetics' ability to regulate their blood sugar levels and promote weight reduction. Despite its potential benefits, clinical trials have revealed that the medication may lead to gastrointestinal side effects, including nausea, vomiting, decreased appetite, dyspepsia, constipation, and diarrhea. These side effects may negatively affect the drug's efficacy and patient tolerance. A comprehensive search of electronic databases such as PubMed, Web of Science, and Cochrane Library, was conducted to find pertinent studies reporting on the frequency and severity of gastrointestinal symptoms in type 2 diabetes patients receiving tirzepatide. This systematic review follows the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Study selection, data extraction, and quality assessment were performed. Six randomized controlled trials with a total of 4,586 patients were included. Most patients received tirzepatide to regulate their blood sugar levels and promote weight reduction, and the comparators were placebo, glucagon-like peptide one receptor agonists drugs, and insulin degludec. The dose of tirzepatide was 5mg, 10mg, and 15mg weekly. The incidence rate of nausea in patients who receive tirzepatide was 20.43%, while the incidence rate in the comparators was 10.47%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 2.90; 95% CI, 1.89 to 4.44; P ≤ 0.00001). The incidence rate of vomiting in patients who receive tirzepatide was 9.05%, while the rate in the comparators was 4.86%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 2.69; 95% CI, 1.67 to 4.36; P ≤ 0.0001). The incidence rate of constipation in patients who receive tirzepatide was 2.54%, while the rate in the comparators was 0.856%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 3.08; 95% CI, 1.83 to 5.20; P ≤ 0.0001). The incidence rate of decreased appetite in patients who receive tirzepatide was 9.64%, while the rate in the comparators was 2.88%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 5.04; 95% CI, 3.01 to 8.45; P ≤ 0.00001). The incidence rate of diarrhea in patients who receive tirzepatide was 16.24%, while the rate in the comparators was 8.63%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 2.07; 95% CI, 1.60 to 2.68; P ≤ 0.00001). The incidence rate of dyspepsia in patients who receive tirzepatide was 7.13%, while the rate in the comparators was 3.31%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 2.52; 95% CI, 1.58 to 4.01; P ≤ 0.0001). Tirzepatide usage is linked to a significant prevalence of gastrointestinal symptoms, including nausea, constipation, decreased appetite, dyspepsia, diarrhea, and vomiting, in people with type 2 diabetes. These findings may influence clinical decision-making and patient counseling on the use of tirzepatide and have significant implications for the medication's tolerance and efficacy. To find ways to reduce these negative effects and improve therapy for type 2 diabetes patients, more research is required.

Comparison of Enamel Surface Integrity after De-Bracketing as Affected by Seven Different Orthodontic Residual Cement Removal Systems.

This study used seven different adhesive removal systems to evaluate and compare enamel surface integrity, heat generation, and time consumed during residual cement removal after de-bracketing. The sample size was 140 human premolars. Teeth were cleaned, mounted, and prepared for orthodontic bracket bonding. Brackets were then debonded using bracket-removing pliers. Teeth were randomly assigned to seven groups based on the residual cement removal system: Group 1: Stainbuster bur, Group 2: Renew diamond bur #129, Group 3: Renew carbide bur, Group 4: OneGloss Complete system, Group 5: Sof-Lex system, Group 6: Enhance Finishing and PoGo Polishing complete kit, and Group 7: Renew friction grip points. The enamel surface was evaluated for roughness before bracketing and after residual cement removal using surface profilometry. The time taken for cement removal was recorded using a digital timer, and heat generation was measured using a laser thermometer before and after cement removal. One-way ANOVA compared the pre- and post-values for enamel surface roughness, temperature, and time consumed. When comparing the difference between the post- and pre-finishing roughness using one-way ANOVA, the Renew diamond bur produced the roughest enamel surface post-removal with a mean of 4.716 µm, while the Sof-Lex recorded the lowest at 0.760 µm. The highest mean temperature was recorded with the Stainbuster bur at 5.545 °C, and the lowest temperature was recorded with the Enhance bur at 2.260 °C. The time for cement removal was the shortest with the Enhance bur at 12.2 s, whereas the time was the longest with the Renew diamond bur at 30.4 s. In conclusion, all the residual cement removal systems used in this clinically simulated study were not able to restore the original enamel surface smoothness. However, the 3M Sof-Lex produced the lowest enamel roughness but with more time consumption and heat generation. When selecting the best residual cement removal system to be used, clinicians should weigh the merits and demerits of each system based on the clinical judgement of the operator.

A Systematic Review of Clinical Pharmacokinetics of Inhaled Antiviral.

Background and Objectives: The study of clinical pharmacokinetics of inhaled antivirals is particularly important as it helps one to understand the therapeutic efficacy of these drugs and how best to use them in the treatment of respiratory viral infections such as influenza and the current COVID-19 pandemic. The article presents a systematic review of the available pharmacokinetic data of inhaled antivirals in humans, which could be beneficial for clinicians in adjusting doses for diseased populations. Materials and Methods: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. A comprehensive literature search was conducted using multiple databases, and studies were screened by two independent reviewers to assess their eligibility. Data were extracted from the eligible studies and assessed for quality using appropriate tools. Results: This systematic review evaluated the pharmacokinetic parameters of inhaled antiviral drugs. The review analyzed 17 studies, which included Zanamivir, Laninamivir, and Ribavirin with 901 participants, and found that the non-compartmental approach was used in most studies for the pharmacokinetic analysis. The outcomes of most studies were to assess clinical pharmacokinetic parameters such as the Cmax, AUC, and t1/2 of inhaled antivirals. Conclusions: Overall, the studies found that the inhaled antiviral drugs were well tolerated and exhibited favorable pharmacokinetic profiles. The review provides valuable information on the use of these drugs for the treatment of influenza and other viral respiratory infections.

Psychological first aid intervention: rescue from psychological distress and improving the pre-licensure nursing students' resilience amidst COVID-19 crisis and beyond.

Background: The public health emergencies such as the COVID-19 pandemic resulted in mental and psychological ramifications on the healthcare professionals. The pre-licensure nursing students found themselves not only fighting against the baneful virus but also weak ego resilience. At this point, enriching the pre-licensure nursing students with psychological first aid (PFA) could help them to recover from the feeling of psychological distress and improve their resilience capacity to encounter any upcoming outbreaks. Methods: A quasi-experimental two groups, a pre-post-test study was used in which sixty-four pre-licensure nursing students completed a baseline survey which revealed high levels of psychological distress and low resilience capacity due to the COVID-19 crisis. The study group engaged in the Psychological First- aid Intervention (PFA) at the end of the clinical practicum course period, while the comparison group received routine psychological support. Results: A significant reduction in the psychological distress levels among students in the PFA group (FET=7.83, P = 0. 001). Likewise, significant improvements in the students' resilience capacity level immediately after the intervention (FET=3.34, P = 0.019) and during the two-month follow-up (FET=12.94, P = 0. 001). The implementation of PFA enhanced the pre-licensure nursing students' psychological health status and resilience capacity levels after their clinical training amid the ambiance of the COVID-19 crisis. Conclusion: The PFA effectively fostered the pre-licensure nursing students' recovery from the COVID-19 related- psychological distress and improve their resilience capacity. The application of RAPID model is recommended to reduce stress and prevent burnout among novice and future nurses who show signs of psychological exhaustion.

The Rate of Appendicular Neoplasm in Patients Who Underwent Appendectomy for Acute Appendicitis at King Abdulaziz Medical City, Riyadh.

Background Appendicitis is a common reason for hospitalization. Rarely do people with acute appendicitis have an appendiceal mass called an abscesses or inflamed phlegmon. The goal of this study was to determine the prevalence of different appendiceal tumors including neuroendocrine tumors, adenocarcinoma, carcinoid, and mucinous and evaluate patient demographic data (e.g., age and gender) at a major tertiary care center in Riyadh, Saudi Arabia. Materials and methods We conducted a cross-sectional analytical review of patient records of 1513 patients who received an appendectomy and were diagnosed with acute appendicitis from 2015 to 2020 at King Abdulaziz Medical City, Riyadh, Saudi Arabia. We used nonprobability sampling to collect the sample. The study included patients older than 14 years. We also recorded patient demographic information, including age, gender, history, and final pathology. Results The mean age of our study population was 27.9 years (standard deviation [SD], 12.3 years). Our study had 958 male patients and 555 female patients. One thousand four hundred fifty-eight patients (96.3%) had right lower quadrant (RLQ) tenderness, and 228 patients had fever (15.0%). One thousand one hundred thirteen patients (73.5%) had rebound tenderness, 1,178 had nausea (77.8%), and 1,100 had high white blood cell (WBC) counts (72.7%). One thousand four hundred eighty-six patients received laparoscopic surgery (98.2%). Most patients (95.3%; n=1,443) had no postoperative complications. Appendicitis pathology was present in 1,381 patients (91.3%). Only 15 patients (1%) had tumor-related pathology, and these patients were significantly older than patients with nontumor-related pathology (p<.001) and had less RLQ pain, rebound tenderness, and pain migration but higher WBC counts. Pain migration was significantly inversely correlated with age: as age increased, pain migration was reported less often (odds ratio, 0.99, 95% confidence interval, 0.98 to 0.99; p=0.001). Conclusion This study aimed to determine the prevalence and types of appendiceal tumors in cases of acute appendicitis and the corresponding patient demographic data at a major tertiary care center in Riyadh, Saudi Arabia. According to our results, patients with appendicitis present with fever, rebound tenderness, nausea, and high WBC count. Appendiceal masses mainly occur in a later age group with less migration of pain and high WBC count. However, migration of pain is inversely related to age. Physicians treating patients with acute appendicitis should bear these data in mind and consider the presence of appendiceal tumors in appropriate patients.

Seasonal variations impact on SARS-CoV-2 incidence and mortality in southern and northern hemispheres: Two years pandemic period based study.

Objectives: The Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) infection is a highly challenging problem in the world. The impact of weather conditions on the spread of SARS-CoV-2 has been hypothesized, but the level of understanding remains lacking. This study investigates the impact of seasonal variations on SARS-CoV-2 incidence and mortality in the Southern and Northern hemispheres. Methods: We enlisted all the countries from both hemispheres and then randomly selected 20 countries, 10 countries from each hemisphere. After that, we recorded the SARS-CoV-2 daily cases and deaths in these selected countries from the Worldometer for the period of two years from December 31, 2019, to December 31, 2021. Results: During the study period, in 10 selected countries of the Northern hemisphere, the number of SARS-CoV-2 cases was 18381.6 ± 419.7 and deaths 300.4 ± 6.4. However, the number of cases in the southern hemisphere is 6282.9 ± 205.8, and mortality was 210.0 ± 7.7. In the Northern hemisphere, the number of SARS-CoV-2 cases (p = 0.001) and deaths (p = 0.001) significantly increased compared to the southern hemisphere. The maximum number of cases and deaths occurred during the winter (18806.4 ± 785.3) and autumn (17034.1 ± 538.4) periods in both the hemisphere compared to spring and summer. Similarly, the number of deaths increased in winter (391.0 ± 13.4, p = 0.001) and autumn (308.6 ± 11.6) compared to spring and summer in both hemispheres. Conclusions: The highest occurrence of SARS-CoV-2 cases and deaths was found during the winter and autumn seasons, while the lowest was found in the spring and summer during the study period of two years. The health officials inform the public about the seasonal occurrence of the SARS-CoV-2 outbreak and take priority preventive measures to minimize the disease burden.

Epidemiological Trends of Human Monkeypox Cases in Northern, Southern, Western, and Eastern Regions in Europe: A Cross-Sectional Study.

Background: The growing amount of monkeypox cases in non-endemic regions raises concerns in societies as a potential pandemic. This study highlights the prevalence and epidemiological trends of a human monkeypox outbreak in various regions in Europe. Methods: This cross-sectional study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia. The data about the monkeypox outbreak in European countries were recorded by the World Health Organization (WHO), and Centers for Disease Control and Prevention (CDC) reports. The period prevalence-based data were recorded from Jan 1, 2022, to July 7, 2022, and analyzed, and epidemiological trends were established in different European regions and countries. Results: In Europe, the human monkeypox rapidly spread in all the four subregions and involved 30 European countries, infecting 6077 people. The rising number of monkeypox cases is identified in Western Europe, 2599 (42.76%); Southern Europe, 1932 (31.79%); Northern Europe, 1487 (24.46%); and Eastern Europe, 59 (0.97%). In Western Europe, significant cases are found in Germany (1304), France (604), the Netherlands (352), Belgium (168), and Switzerland (131). In Northern Europe, it is found in the United Kingdom (1351), Ireland (44), Sweden (28), and Denmark (26); in Southern Europe, it is found in Spain (1256), Portugal (415), and Italy (233). However, a smaller number of cases are found in Eastern European states, Hungary (22), Poland (13), and Romania (12). The results further revealed that the number of monkeypox cases per million people in Northern Europe was 14.40%; Southern Europe, 13.49%; Western Europe, 13.26%; and Eastern Europe, 0.70%. The highest monkeypox cases per million population are found in Portugal, 40.70; Gibraltar, 29.68; Spain, 26.86; the United Kingdom, 19.90; Malta, 18.12; the Netherlands, 20.54; Germany, 15.56; Switzerland, 15.14; Belgium, 14.50; France, 9.27; and Ireland, 8.90. Conclusions: In a short period, the monkeypox cases swiftly spread in 30 non-endemic European countries and involved all four European regions. The healthcare authorities must take timely decisions to control the outbreak of human monkeypox disease, as the world cannot afford the global burden of human monkeypox outbreak as another potential pandemic.

Saudi consensus statement on biologic treatment of chronic plaque psoriasis (2020).

Psoriasis is a common chronic and complex inflammatory skin disease that affects over 125 million people worldwide. Management of psoriasis in daily clinical practice in Saudi Arabia is variable. Local preferences for management differ, which may have a bearing on the treatment selection. Biologic therapy is now a well-established strategy for managing moderate-to-severe plaque psoriasis. There is a clear need for national consensus statements due to the extended role and high availability of literature on these agents. As a result of an initiative of the Ministry of Health, a multidisciplinary expert panel of dermatologists and pharmacists with practical experience in the clinical management of psoriasis were invited to be part of a work group to update the previous practical guidelines on the biologic treatment of psoriasis published in the Journal of Dermatological Treatment, 2014. The overall aim of this consensus document is to deliver evidence-based recommendations on the use, screening, and monitoring of biologic therapy in patients with moderate-to-severe plaque psoriasis. These recommendations also address the use of biologic therapy in special patient populations. They were developed after rigorous evaluation of existing international guidelines as well as the latest emerging evidence. Updates of the present consensus document will be provided as needed to incorporate new data or agents.

Locomotor Behavior Analysis in Spinal Cord Injured Macaca radiata after Predegenerated Peripheral Nerve Grafting-A Preliminary Evidence.

INTRODUCTION: Primate animal models are being utilized to explore novel therapies for spinal cord injuries. This study aimed to evaluate the efficiency of the transplantation of predegenerated nerve segments in unilateral spinal cord-hemisected bonnet monkeys' (Macaca radiata) locomotor functions using the complex runways. MATERIALS AND METHODS: The bonnet monkeys were initially trained to walk in a bipedal motion on grid and staircase runways. In one group of trained monkeys, surgical hemisection was made in the spinal cord at the T12-L1 level. In the other group, hemisection was induced in the spinal cord, and the ulnar nerve was also transected at the same time (transplant group). After one week, the hemisected cavity was reopened and implanted with predegenerated ulnar nerve segments obtained from the same animal of the transplant group. RESULTS: All the operated monkeys showed significant deficits in locomotion on runways at the early postoperative period. The walking ability of operated monkeys was found to be gradually improved, and they recovered nearer to preoperative level at the fourth postoperative month, and there were no marked differences. CONCLUSION: The results demonstrate that there were no significant improvements in the locomotion of monkeys on runways after the delayed grafting of nerve segments until one year later. The failure of the predegenerated nerve graft as a possible therapeutic strategy to improve the locomotion of monkeys may be due to a number of factors set in motion by trauma, which could possibly prevent the qualities of regeneration. The exact reason for this ineffectiveness of predegenerated nerve segments and their underlying mechanism is not known.

Effect of Zamzam Water on Microhardness of Primary Tooth Enamel After Erosion Induced by Claritin Syrup: An In-vitro Study.

BACKGROUND: Dental erosion is an irreversible damage to hard tissues in the mouth due to acid dissolution not induced by microorganisms. Oral medications contributed to the etiology of dental erosion. Among these medications, antihistamine-containing syrups were reported to have a considerable erosive effect on hard dental tissues. OBJECTIVE: The objective was to evaluate the effect of Zamzam water on the microhardness of primary tooth enamel after erosion induced by Claritin™ syrup. MATERIALS AND METHODS: The present in-vitro study was conducted on 25 primary central incisor teeth. The labial surfaces of the specimens were prepared for microhardness testing. Baseline microhardness was measured first, then the samples were submerged in the erosive agent Claritin™ syrup, for 30 min every 12 h for 12 days. Thereafter, all the teeth were placed in Zamzam water for 30 min every 12 h for 12 days. The microhardness was measured by the Vickers hardness tester and expressed as Vickers microhardness value (VH). The measurements were completed three times for the same sample: baseline, after erosion, and after Zamzam treatment. Data were analyzed statistically using one-way repeated analysis of variance (ANOVA) followed by Tukey's post hoc test. RESULTS: The primary teeth included in this study showed a significant increase in their surface microhardness after Zamzam water treatment; the mean value of VH was increased from 33.12 ± 1.62 to 89.32 ± 8.52 (P-value <0.0001). CONCLUSION: Zamzam water could be introduced as a part of the management of dental erosion in the primary dentition.

Blood donation among university students: practices, motivations, and barriers in Saudi Arabia.

CONTEXT: Blood transfusion is an essential medical procedure conducted with various purposes to provide patients with blood needed. The procedure saves patients' lives, as blood cannot be manufactured artificially and can only be obtained from human blood sources. AIMS: To assess the awareness of, perceptions of, motivations regarding, and barriers to blood donation among a sample of Jazan University students in the Kingdom of Saudi Arabia (KSA). SETTINGS AND DESIGN: An observational cross-sectional study was conducted among the undergraduate students of Jazan University. MATERIALS AND METHODS: Stratified random sampling was used to collect information from 440 students, and a predesigned, structured questionnaire was used to collect data on the study variables. STATISTICAL ANALYSIS: Involved descriptive statistics and inferential statistics. SPSS was used for data analysis. RESULTS: The prevalence of blood donation was 29.0% (95% CI, 25.0-33.3), significantly higher for males at 44.3% (95% CI, 38.3-50.4) than for females at 10.5% (95% CI, 7.3-16.0; P < 0.001), and with odds ratio (OR) = 6.8; [95% CI, 4.1-11.2] than females. Students' level of knowledge regarding blood donation was low. The main barriers to blood donation were identified as being unqualified for blood donation (57.5%) and risk of contracting infectious disease (48.7%) and the desire to donate in the future to a close friend (38.6%). The main motivations for donating blood were identified as religious reasons (77.5%), altruism (77.5%), and to serve the homeland and meet the call of need (77.5%). CONCLUSIONS: The prevalence of blood donation was found to be low, and students' knowledge regarding blood donation appeared to be lacking. The development of awareness programs among the university's students will address students' misconceptions about blood donation and encourage them to join donation campaigns.

The Incidence of Congenital Heart Defects in Offspring Among Women With Diabetes in Saudi Arabia.

BACKGROUND: The risk of congenital anomalies is increased in infants of diabetic mothers (IDM). The most frequent cardiac anomalies in IDMs include ventricular septal defect, transposition of great arteries, and aortic stenosis. OBJECTIVE: Estimating the incidence of infants with congenital heart defects (CHD) whose mothers have diabetes in Saudi Arabia at a tertiary hospital in the National Guard Health Affairs (NGHA) system. MATERIALS AND METHODS: This study was a retrospective cohort. The population was all births of type 1 and type 2 diabetic mothers and non-diabetic mothers (also mothers with gestational diabetes) in NGHA by following the exclusion criteria, which were mothers over 40 and below 20 years of age, and other risk factors such as drug-induced congenital disease. The data was from deliveries from January 1st 2018 to January 1st 2019. Data were collected by chart review using the Best-Care system at NGHA hospital. Statistical Package for the Social Sciences (SPSS) version 20 (IBM Corp., Armonk, NY, USA) was used for the statistical analysis. RESULTS: A total of 1838 diabetic mothers and non-exposure, non-diabetic mothers, with the outcome of whether the infant had CHD, were included in this study. Most of the mothers (544, 30.11%) were aged 30-34 years old. About two-thirds of mothers, 1161 (63.24%), weren't diabetic, 500 (27.23%) had gestational diabetes, 132 (7.19%) were type 2 diabetes (T2DM), and 43 (2.34%) were type 1 diabetes (T1DM). Two hundred eighteen (11.82%) offspring had CHD, and the remaining 1625 (88.17%) did not. The most frequent echocardiographic abnormalities in infants of diabetic mothers were patent ductus arteriosus (PDA) (31.75%), patent foramen ovale (PFO) (31.75%), and atrial septal defect (ASD) (23.64%). CONCLUSION: The incidence of CHD among infants of included mothers in this cohort study was 11.82%. The most frequent echocardiographic abnormalities in the infants of diabetics were PDA and PFO. The incidence of CHD was higher among mothers who had T1DM followed by T2DM, and whose ages were between 30-34.

Influence of Social Media towards the Selection of Hollywood Smile among the University Students in Riyadh City.

BACKGROUND: Hollywood smile refers to the aesthetic development of dental appearance inspired by the beauty displayed by the movie actors. Therefore, the present study was conducted to determine the extent of social media effect on the decision making of university students towards selecting Hollywood smile as the choice of their aesthetic treatment. MATERIALS AND METHODS: This cross-sectional study was conducted by utilizing a self-designed closed-ended questionnaire among under-graduate students from the various public as well as private universities of Riyadh city. The questionnaire was constructed online using Google forms and began with questions related to demographics; questions like Do you notice celebrity's smile on social media? Have you visited a dentist solely after getting inspired by a celebrity's smile? etc., Responses were on a 5-point likert scale ranging from highly dissatisfied or strongly disagree to highly satisfied or strongly agree whenever applicable. Chi-square test was used to compare the differences among the groups with the value of significance kept under 0.05 by using SPSS version 19.
