Abstract Purpose To investigate the health-related factors and analyze the expression of epigenetic related genes and inflammatory genes in metabolic syndrome Trigger Finger (TF) and smoker TF. Methods Samples from patients’ fingers with symptomatic TF were collected. There were seven groups: healthy control group, carpal tunnel syndrome (as a control for gene expression analysis), TF, diabetic TF, hypertensive TF, dyslipidemic TF and smoker TF. The expression levels of epigenetic related genes and inflammatory genes in metabolic syndrome TF and smoker TF were evaluated by the reverse transcription–polymerase chain reaction (RT-PCR) technique. The Perceived Stress Scale (PSS), Pittsburgh Sleep Quality Index (PSQI) questionnaires, disability of the arm, shoulder and hand (DASH) and numeric pain rating scale were given to the participants to fill out. Results There was a significant increase in hand dysfunction in the metabolic TF groups and smoker group compared to the TF group (p

Periodontal disease, Chronic migraine, Headache, Leptin, Chronification, Dentistry, and RK1-715

Migraine is a neurologic illness that produces intense throbbing pain on one side of the head and affects roughly 1 billion people worldwide. Recent research indicates a relationship between periodontitis and chronic migraines. This study aimed to review the association between chronic migraines and periodontitis through a systematic literature review.Four research databases (Google Scholar, PubMed, ProQuest, and SpringerLink) were searched according to PRISMA guidelines to retrieve the studies included in this review. A search strategy was developed to answer the study question with appropriate inclusion and exclusion criteria. Out of 34 published studies, 8 studies were included in this review. Three of the studies were cross-sectional, 3 were case-control, and 2 were clinical report and medical hypothesis papers. Seven of the 8 included studies showed that there is an association between periodontal disease and chronic migraine. The elevated blood levels of some biomarkers such as leptins, ProCalcitonin (proCT), calcitonin gene-related peptides (CGRPs), Pentraxin 3 (PTX3), and Soluble Tumor Necrosis Factor-like Weak Inducer Of Apoptosis (sTWEAK) play a significant role in this association. The limitations include a small sample size, the influence of anti-inflammatory drugs, and a self-reported headache measure that is subject to misclassification bias.This systematic review reveals a supposed correlation between periodontal disease and chronic migraine, as evidenced by various biomarkers and inflammatory mediators. This suggests that periodontal disease could potentially contribute to the development of chronic migraine. However, to further assess the potential benefits of periodontal treatment in patients with chronic migraine, additional longitudinal studies with larger sample sizes and interventional studies are needed.

birth defects, pattern, prevalence, Saudi Arabia, Medicine, Pediatrics, and RJ1-570

Introduction: Birth defects are a significant concern since they can lead to permanent disability and death. This study comprehensively reviews the prevalence and patterns of birth defects in Saudi Arabia. Methods: A systematic analysis of the literature retrieved from three databases (Pub Med, Science Direct, and the Saudi digital library) published between 1989 and 2022 was performed. Observational studies that addressed the prevalence and patterns of birth defects in Saudi Arabia were chosen based on the eligibility criteria, while systematic reviews, review articles, non-relevant articles, and studies that did not fulfill the eligibility criteria were excluded. Quality and risk of bias were evaluated based on the JBI and GRADE tools, respectively. Results: We identified 26 eligible publications of 1277 records that included 297,668 patients from different regions of Saudi Arabia. The highest overall prevalence of birth defects was 46.5 per 1000 live births compared to a lowest rate of 8.6 per 1000 in one study. Several studies have reported positive associations of consanguinity, maternal folic acid supplementation, family history of birth defects or genetic abnormalities, and maternal co-morbidities. The most frequent birth defects include cardiac, genitourinary, craniofacial, and nervous system defects. Conclusion: Robust findings have improved our understanding of the prevalence and pattern of birth defects in Saudi Arabia. Importantly, future studies will likely require multicenter collaboration to arrive at appropriate sample sizes in the context of the effects of risk factors on elevated prevalence. Furthermore, quantitative data require careful evaluation in more complex statistical models.

Introduction Electronic cigarettes (e-cigarettes) have become one of the most common forms of nicotine delivery used by youth and young adults worldwide. Given the lack of epidemiologic data in Kuwait, this study sought to estimate the prevalence of e-cigarette use, assess perceptions of harm and addictiveness of e-cigarettes, measure the level of dependence on e-cigarettes and assess factors associated with dependence level among adults. Methods A cross-sectional study enrolled adults (n=3032, aged ≥18 years) living in Kuwait using a web-based questionnaire. Participants self-reported ever and current (past 30-day) e-cigarette use and self-completed the 10-item Penn State E-cigarette Dependence Index. Associations were evaluated using multinomial logistic regression. Results The prevalence of ever and current e-cigarette use was estimated to be 40.2% (1220/3032) and 29.4% (892/3032), respectively. The prevalence of current e-cigarette use was higher in males compared to females (47.6% vs 14.4%, p

Abstract Globally, COVID-19 affected radiopharmaceutical laboratories. This study sought to determine the economic, service, and research impacts of COVID-19 on radiopharmacy. This online survey was conducted with the participation of employees from nuclear medicine and radiopharmaceutical companies. The socioeconomic status of the individuals was collected. The study was participated by 145 medical professionals from 25 different countries. From this work, it is evident that 2-deoxy-2-[18F]fluoro-D-glucose (2-[18F]FDG), and 99m Tc-labeled macro aggregated albumin 99mTc-MAA were necessary radiopharmaceuticals used by 57% (83/145and 34% (49/145;) respondents, respectively for determining how COVID infections affect a patient’s body. The normal scheduling procedure for the radiopharmacy laboratory was reduced by more than half (65%; 94/145). In COVID-19, 70% (102/145) of respondents followed the regulations established by the local departments. Throughout the pandemic, there was a 97% (141/145) decrease in all staffing recruitment efforts. The field of nuclear medicine research, as well as the radiopharmaceutical industry, were both adversely affected by COVID-19.

Choose a surgeon, Factors, Social media, surgeon's qualifications, Public attitudes, Surgery, and RD1-811

Aim: It is a complex decision for patients and their families to select a qualified surgeon who meets their needs. Understanding these needs enables surgeons to build stronger relationship with patients. This study aimed to identify influencing factors, variables, and criteria that individuals consider when selecting surgeons for elective surgeries. Methods: This is a nationwide cross-sectional study conducted among patients who have undergone elective surgeries in Saudi Arabia. The data were collected with an anonymous self-administered pre-validated questionnaire. The collection of data was carried out through web-based questionnaires using google forms. The questionnaire contains socio-demographic characteristics (i.e., age, gender, education, etc.) and different factors to assess patients' perceptions in choosing a surgeon. Result: Patients' overall number was 3133 (56.2 % females vs 43.8 % males). The most common age group was 18 to 34 years old (63.7 %). The prevalence of patients who were able to choose the right surgeon to perform an operation was 79.8 %. Patients' top choice when selecting a surgeon was according to the surgeon's manner followed by the qualifications then the reputation. Females are choosing a surgeon according to his/her manner while males are choosing according to his/her qualifications. Conclusion: Surgeons' manner and qualifications are the most considered factors among when selecting a surgeon while the realistic factors such as accreditation of a facility and surgeon's scientific roles, quality improvement, and patient safety are ignored among the public. This requires condensed educational efforts and further research to determine the advertisements and social media effects on patients' decisions related to their health.

Introduction: Nonconvulsive status epilepticus (NCSE) is an important and often unrecognized cause of impaired awareness especially in critically ill patients, which can easily be missed. Electroencephalography (EEG) findings in clinically suspected cases are the mainstay of diagnosis. Review summary: The EEG diagnostic criteria for NCSE have evolved over the past three decades. Furthermore, recent advancements in EEG technologies such as continuous EEG monitoring, and emergency department EEG, along with development of different diagnostic criteria, have increased the detection rate for NCSE in suspected cases. However, treating physicians should have a higher index of clinical suspicion and a lower threshold for recommending this valuable investigation. The introduction of different diagnostic criteria has made it easier for electroencephalographers to report NCSE; nevertheless, diagnosis is not always straightforward. This narrative review aimed to define and discuss the available literature on different EEG diagnostic criteria for NCSE. Conclusion: There is a need for further prospective research to strengthen the diagnostic accuracy of the available diagnostic criteria, the modified Salzburg Consensus Criteria for NCSE (mSCNC) and updated American Clinical Neurophysiology Society (ACNS) 21 criteria, to verify their accuracy to detect NCSE in comatose patients.

Anti-Epileptic drugs, Levetiracetam, Pharmacokinetics, Liver enzymes, High-performance liquid chromatography, Saudi Arabia, Therapeutics. Pharmacology, and RM1-950

Background: Epilepsy is a common global neurological disorder. About 30% of epileptic patients are managed with anti-epileptic Drugs (AEDs). Since 2000, Levetiracetam (LEV) has been marketed around the world as an AED under the brand name Keppra, and recently more generics are found in the Saudi market as cheaper alternatives. The objective of this study is to evaluate the bioequivalence of LEV brand and generics available in the Saudi market in mice. Methods: Pharmacokinetics (PK), liver function test, and behavioral studies were conducted for LEV brand and generic in different groups of Blab/c mice. Results: PK results show a significance difference in PK parameters mostly evidenced with generic 3, then generic 2. The only significant different between Keppra and generic 1 was in T1/2. In addition, Keppra did not significantly increase liver enzymes in comparison to other generics. On the other hand, other generics showed less favorable results in increasing liver enzymes. Keppra reduced the number and intensity of epileptic attacks, had no mortality rate due to epilepsy, and was associated with less sever seizures attacks. Conclusion: Keppra, the brand form of LEV, has better safety and efficacy profiles in mice compared to 3 generics found in the Saudi market. Therefore, we recommend evaluating the same parameters tested in this study in patients utilizing similar generics and brand to establish the existence of bioequivalence between LEV brand and generics.

Surgery and RD1-811

Summary:. Silicone liquid (polydimethylsiloxane) is an inert material commonly used for cosmetic purposes. A combination of both systematic and local devastating complications can cause end-organ toxicity and multi-organ dysfunction. In this article, we examine the literature and present a case of a patient who presented with lower extremity filler migration and granuloma formation 11 years post gluteal silicone injection. A 31-year-old woman who had received a gluteal silicone injection 11 years ago was experiencing painful erythema, progressive fibrosis, and swelling as the result of the injection. The patient was diagnosed with postfiller autoimmune syndrome. Multiple surgical interventions were conducted to remove the permanent filler from her left knee. As a result of multiple surgical sessions, the patient has been managed successfully with no relapses. This case demonstrated complications of an unusual silicone injection technique for gluteal augmentation. Despite silicone being considered inert, complications can arise years after injection, necessitating extensive medical intervention. This case also raises questions regarding the systemic effects of silicone fillers, warranting further research. Through this report, we aimed to enhance awareness and management of similar future cases.

glycated hemoglobin, HbA1c level, acute ischemic stroke, intracranial large artery atherosclerotic disease, functional outcomes, predictor, Neurology. Diseases of the nervous system, and RC346-429

ObjectiveThis study aimed to investigate the effect of the glycated hemoglobin A1c (HbA1c) level on the functional outcome (FOC) in patients with intracranial large artery atherosclerotic disease (ICLAD)-related acute ischemic stroke (AIS).MethodsThis retrospective study enrolled patients with ICLAD-related AIS who were admitted to King Fahd University Hospital between January 2017 and September 2021. Patients were divided into two groups based on the optimal cutoff HbA1c level determined using receiver operating characteristic curve analysis—those with HbA1c ≤6.9% and those with HbA1c >6.9%. Demographic and other clinical characteristics were compared between the two groups using chi-square tests. The association between HbA1c and 90-day FOC was assessed using the chi-square test and odds ratios (ORs). Multivariate analysis was performed to adjust for confounding factors.ResultsA total of 140 patients were included in the analysis. A significant association was observed between the HbA1c level and FOC. Compared to patients with HbA1c ≤6.9%, patients with HbA1c >6.9% were more likely to have an unfavorable FOC [p = 6.9% and unfavorable FOC was sustained even after adjusting for confounding factors (p = 0.008) and atherosclerosis risk factors (p = 0.01). HbA1c >6.9% was also associated with higher ORs for in-hospital complications (p = 0.06, OR = 1.34, 95% CI = 1.02–1.77) and mortality (p = 0.07, OR = 1.42, 95% CI = 1.06–1.92) although these associations did not attain significant p-values.ConclusionHbA1c >6.9% was significantly associated with unfavorable FOC in ICLAD-related AIS. However, further studies with larger sample sizes are required to verify whether HbA1c is an independent predictor of poor FOC. Nevertheless, targeting HbA1c

death, Jordan, metastasis, retinoblastoma, survival, Medicine (General), and R5-920

PurposeTo analyze causes and prognostic factors for death among Retinoblastoma (Rb) patients treated at a single specialized tertiary cancer center in Jordan.MethodsWe reviewed the mortality causes for all Rb patients who have been treated at the King Hussein Cancer Center between 2003 and 2019 and were followed for at least 3 years after diagnosis. The main outcome measures included demographics, laterality, tumor stage, treatment modalities, metastasis, survival, and causes of death.ResultsTwenty-four (5%) of the 478 patients died from retinoblastoma and 5-year survival was 94%. The mean age at diagnosis was 15 months (median, 18 months; range, 4–38 months); eight (33%) received diagnoses within the first year of life. Eleven (46%) were boys, 16 (67%) had bilateral disease, and 3 (13%) had a positive family history. The stage for the worst eye was C for 1 (4%) patient, D in 6 (25%) patients, and E (T3) in 15 (63%) patients. Two patients had extraocular Rb at diagnosis, and four of the patients who had intraocular Rb at diagnosis refused treatment and then came back with extraocular Rb. In total, extraocular disease was encountered in six eyes (six patients). After a 120-month median follow-up period, 24 patients (5%) died of second neoplasms (n = 3) or metastases (n = 21). Significant predictive factors for metastasis and death included advanced IIRC tumor stage (p

Clostridium difficile infection (CDI), Vedolizumab, Crohn’s disease, Ulcerative colitis, Inflammatory bowel disease, 5- Aminosalicylates acid, Therapeutics. Pharmacology, and RM1-950

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.

Analgesics, Pain, Suicide, Pregabalin, Gabapentin, Anticonvulsants, Public aspects of medicine, and RA1-1270

Summary: Background: Analgesics prescriptions may provide a marker for identifying individuals at higher risk of suicide. In particular, awareness of which analgesics are implicated may help clinicians assess and modify risk. Method: A case–control study in England using the Clinical Practice Research Datalink (for primary care records) linked with hospital and national mortality electronic registries. We included patients aged ≥15 who died by suicide between 2001 and 2019 (N = 14,515), to whom we individually matched 580,159 controls by suicide date and general practice (N = 594,674). Odds ratios (ORs) for suicide, controlled for age and sex, were assessed using conditional logistic regression. Findings: Suicide risks were highest in those prescribed adjuvant analgesics (pregabalin, gabapentin and carbamazepine) (adjusted OR 4.07; 95% confidence intervals CI: 3.62–4.57), followed by those prescribed opioids (adjusted OR 2.01; 95% CI: 1.88–2.15) and those prescribed non-opioid analgesics (adjusted OR 1.48; 95% CI: 1.39–1.58) compared to those not prescribed these medications. By individual analgesic, the highest suicide risks were seen in patients prescribed oxycodone (adjusted OR 6.70; 95% CI: 4.49–9.37); pregabalin (adjusted OR 6.50; 95% CI: 5.41–7.81); morphine (adjusted OR 4.54; 95% CI: 3.73–5.52); and gabapentin (adjusted OR 3.12; 95% CI: 2.59–3.75). Suicide risk increased linearly with the number of analgesic prescriptions in the final year (p

Social isolation, Depression, Socialization, Adolescents, Psychiatry, and RC435-571

Abstract Background Social isolation can be defined as the absence of social interactions, contacts, and relationships with family, friends, and neighbors. According to some studies, social isolation was associated with depressive symptoms. At least one out of every five teenagers suffer from a diagnosable mental health problem that impairs their function. Saudi Arabia has a significant adolescent population; however, there are few studies conducted in Saudi Arabia to assess social isolation and its psychological impact among adolescents. This research is intended to study the prevalence of social isolation among adolescents in Riyadh and its association with depression symptoms. Methods A cross-sectional study was conducted among 483 adolescents living in Riyadh, Saudi Arabia. An online self-administered questionnaire was used, and it was composed of three sections which are sociodemographic characteristics, assessment of social isolation, and assessment of depression symptoms. Results The study reported the prevalence of social isolation among adolescents was 10.14%. The prevalence of depression symptoms among adolescents was high (31.68%). There was a significant association between social isolation and symptoms of depression among the studied sample (χ 2 = 12.3, p = 0.002). It was found that being a male, living with both parents, and having low income are significant predictors of social isolation among adolescents; with r 2 = 0.08 and p-value

Infectious bronchitis virus (IBV), DMV/1639, Autogenous vaccine, Layer, Canada, Microbiology, QR1-502, Infectious and parasitic diseases, and RC109-216

The emergence of the Canadian Delmarva (DMV)/1639 infectious bronchitis virus (IBV) type strains was associated with egg production disorders in Eastern Canadian layer operations. While developing vaccines for novel IBV variants is not typically a reasonable approach, the consideration of an autogenous vaccine becomes more appealing, particularly when the new variant presents significant economic challenges. The current study aimed to compare the efficacies of two vaccination programs that included heterologous live priming by Massachusetts (Mass) and Connecticut (Conn) type vaccines followed by either a commercial inactivated Mass type vaccine or a locally prepared autogenous inactivated DMV/1639 type vaccine against DMV/1639 IBV challenge. The protection parameters evaluated were egg production, viral shedding, dissemination of the virus in tissues, gross and microscopic lesions, and immunological responses. The challenge with the DMV/1639 caused severe consequences in the non-vaccinated laying hens including significant drop in egg production, production of low-quality eggs, serious damage to the reproductive organs, and yolk peritonitis. The two vaccination programs protected the layers from the poor egg-laying performance and the pathology. The vaccination program incorporating the autogenous inactivated DMV/1639 type vaccine was more effective in reducing vial loads in renal and reproductive tissues. This was associated with a higher virus neutralization titer compared to the group that received the commercial inactivated Mass type vaccine. Additionally, the autogenous vaccine boost led to a significant reduction in the viral shedding compared to the non-vaccinated laying hens. However, both vaccination programs induced significant level of protection considering all parameters examined. Overall, the findings from this study underscore the significance of IBV vaccination for protecting laying hens.

Nanosponges, crosslinker, nanocarrier, cyclodextrin, analgesics, drug efficacy, Therapeutics. Pharmacology, and RM1-950

AbstractCyclodextrin nanosponges are solid nanoparticles, designed by cross-linking of cyclodextrin polymer; it has been used widely as a good delivery system for water insoluble drugs. The aim of this study is to enhance the solubility of Piroxicam (PXM) using β-Cyclodextrin based nanosponges formulations. PXM nanosponge (PXM-NS) formulations were prepared using β-cyclodextrin and carbonyldiimidazole as a cross linker, three ratios of β-cyclodextrin to crosslinker in addition to three drug to nanosponges ratios were tested. Piroxicam nanosponge formulations were characterized for its particle size, zeta potential, physical compatibility and in vitro release. Stability studies at three temperatures (4 °C, 25 °C and 40 °C) were done for optimal formula. Finally, the in vivo analgesic activity and pharmacokinetic parameters of the optimal formula were conducted. The optimized PXM-NS formula (PXM-NS10) showed particle size (362 ± 14.06 nm), polydispersity index (0.0518), zeta potential (17 ± 1.05 mV), and %EE (79.13 ± 4.33). The dissolution study showed a significant increase in the amount of PXM dissolved compared with the unformulated drug. Stability studies confirmed that nanosponge showed accepted stability for 90 days at 4 °C and 25 °C. In vivo analgesic studies verified that there was a significant enhancement in the analgesic response to PXM in mice, and 1.42 fold enhancement in the relative bioavailability of PXM-NS10 as compared to commercial tablets. Nanosponge prepared under optimal conditions is an encouraging formula for increasing the solubility and therefore the bioavailability of Piroxicam.

Epidermolysis bullosa, Supraglottic stenosis, Laryngeal manifestation, Otorhinolaryngology, and RF1-547

Epidermolysis bullosa (EB) is a group of inherited disorders characterized by increased vulnerability to mechanical stress at the dermo-epidermal junction and basilar layer of the epidermis. Laryngeal EB involvement is a major and life-threatening manifestation of the disease. Due to the nature of EB, granulation tissue and stenosis can occur, usually at the glottic, subglottic, or supraglottic levels, as seen in our patients.We described cases in which four patients with EB presented with supraglottic stenosis and were managed at tertiary hospital in Saudi Arabia. The clinical and therapeutic characteristics of all patients are discussed.

Abstractive summarization, novelty, warm-started models, deep learning, metrics, Electrical engineering. Electronics. Nuclear engineering, and TK1-9971

Abstractive summarization is distinguished by using novel phrases that are not found in the source text. However, most previous research ignores this feature in favour of enhancing syntactical similarity with the reference. To improve novelty aspects, we have used multiple warm-started models with varying encoder and decoder checkpoints and vocabulary. These models are then adapted to the paraphrasing task and the sampling decoding strategy to further boost the levels of novelty and quality. In addition, to avoid relying only on the syntactical similarity assessment, two additional abstractive summarization metrics are introduced: 1) NovScore: a new novelty metric that delivers a summary novelty score; and 2) NSSF: a new comprehensive metric that ensembles Novelty, Syntactic, Semantic, and Faithfulness features into a single score to simulate human assessment in providing a reliable evaluation. Finally, we compare our models to the state-of-the-art sequence-to-sequence models using the current and the proposed metrics. As a result, warm-starting, sampling, and paraphrasing improve novelty degrees by 2%, 5%, and 14%, respectively, while maintaining comparable scores on other metrics.
