A public health view and comparison between online and on-campus learning to evaluate sleep and mental health among undergraduate students.

Background: The COVID-19 pandemic changed people's lives. The majority had to adapt to working online including students. The shift to online learning caused serious sleep and mental health issues among students. This study aimed to examine the variations between the prevalence of sleep and mental health problems among undergraduate students during the periods of online learning and on-campus learning. Method: An online survey was distributed to medical students in Saudi Arabia. Results: A total of 110 participated in the study (age = 21 ± 1.4 years). The on-campus anxiety (8.2 ± 6.3) was significantly higher than online anxiety (5.5 ± 5.1). On-campus daytime sleepiness (8.5 ± 4) was significantly higher when compared to online daytime sleepiness (6.7 ± 4.6). Although not significant, the on-campus stress (7.7 ± 5.7) and insomnia (12 ± 7.3) were higher than online stress (6.9 ± 5.5) and insomnia (11.5 ± 6). The online depression (6.6 ± 5.7) was higher than the mean on-campus depression (5.8 ± 5.4). A significant strong positive correlation was found between on-campus anxiety and on-campus stress. A significant moderate positive correlation was detected between on-campus anxiety and on-campus daytime sleepiness. A weak but significant correlation was found between on-campus anxiety and on-campus insomnia. On-campus anxiety was significantly predicted by the following model, which included on-campus stress, insomnia, and daytime sleepiness (P < .001). Conclusion: Medical students reported lower anxiety, daytime sleepiness, stress, and insomnia during their online learning compared to on-campus learning. Only depression was higher during online learning compared to on-campus learning.

Alström Syndrome: A Challenging Case Study of a Female Saudi Patient With Type 2 Diabetes Mellitus and Complete Vision Loss.

Alström syndrome is a genetic disease that impacts numerous systems in the human body. The symptoms can vary and appear gradually. Childhood obesity, heart disease (cardiomyopathy), abnormalities in vision, and hearing issues are the main symptoms of this disorder in children. Diabetes mellitus, hepatic issues, and renal dysfunction can all occur over time. Genetic alterations in the ALMS1 gene are the cause of Alström syndrome. It has an autosomal recessive inheritance pattern. We address the case of a Saudi woman in her 20s. She had been initially referred for type 2 diabetes, intellectual disability since early childhood, metabolic acidosis, and micrognathia; however, she also exhibited blindness, chronic kidney disease (CKD), and hearing loss, all of which are indicative of Alström syndrome. DNA testing showed that she has a homozygous pathogenic variant in the ALMS gene. Autosomal recessive Alström syndrome has been confirmed as a genetic diagnosis. No other clinically significant variations were found that are associated with the mentioned phenotype. By reporting this mutation, we hope to learn more about the genotypic range of the disease, particularly in the Saudi population. As each member of the family underwent genetic testing, we established a stringent follow-up schedule for our patient and her family.

Assessment of Arabic Web-Based Knowledge About Root Canal Treatment: An Infodemiologic Study.

BACKGROUND: Root canal treatment (RCT) is a vital dental procedure aimed at preserving tooth function and minimizing infection. Access to accurate and comprehensive information about RCT is crucial for informed decision-making. With the increasing reliance on the Internet for health-related information, it is essential to evaluate the quality and readability of web-based RCT content, particularly in Arabic-speaking regions. METHODS: This study conducted an extensive web search using three major search engines (Google, Yahoo, and Bing) to identify Arabic-language websites providing information on RCT. Inclusion criteria required websites in Arabic with comprehensive RCT content. Quality assessment employed the DISCERN instrument, JAMA benchmarks, and Health on the Net (HON) assessment tools, while readability was assessed using Flesch Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG), and Flesch Reading Ease (FRE) metrics. RESULTS: Out of 152 websites included, the majority were affiliated with university/medical centers (56.58%) and non-profit organizations (28.29%). Quality assessment revealed that the mean DISCERN score was 2.82, indicating moderate quality. Only one website achieved a high DISCERN score. JAMA benchmarks showed limited compliance, with only two websites meeting all criteria. The HON code was found on only five websites. Readability analysis indicated that most websites were reasonably easy to read by the general population. CONCLUSION: This study highlights the significant gap in the quality and reliability of web-based health information related to RCT in Arabic. While the majority of websites examined in this study did not meet established quality standards, there is a clear need for improvements in the accuracy and comprehensiveness of online resources. Patients seeking information on RCT should exercise caution and consider consulting healthcare professionals for trustworthy guidance. Further research should explore strategies to enhance the quality of web-based health information and expand the scope of evaluation to ensure that individuals have access to reliable resources for making informed decisions about their dental health.

The Relationship Between Blood Culture, C-reactive Protein, and Neonatal Sepsis: A Cross-Sectional Study.

Background Sepsis is one of the most common causes of morbidity and mortality in newborns. Diagnosis of neonatal sepsis may be difficult because the clinical presentations are often nonspecific. Neonatal sepsis may have an early onset (zero to three days) or a late onset (four days or later). Onset is most rapid in premature neonates. In this study, we aimed to assess the correlation between positive cultures, high C-reactive protein (CRP) levels, and the diagnosis of neonatal sepsis. Methodology This descriptive, prospective, cross-sectional study was undertaken over four months starting from December 15, 2019, to April 15, 2020, in Atbara Teaching Hospital, Sudan. Data were collected from 71 patients. CRP levels were measured, and blood cultures were performed. Results High CRP level >10 mg/L was seen in patients having positive blood culture (55.3%), mainly in preterm babies (CRP >10 mg/dL (61.1%), positive culture (55.6%)) and very low birth weight babies (CRP >10 mg/dL (83.3%) and positive culture (67%)). Conclusions Our findings suggest that Klebsiella is an important cause of neonatal sepsis. CRP was positive in babies mainly with proven sepsis. There is a high correlation between CRP and blood culture in patients with neonatal sepsis which may give access to remodeling the prioritization of the management options in the clinical setting.

Relationship Between Depression, Anxiety, Stress, and Weight Self-Stigma Among Youths in Saudi Arabia: A Nationwide Study.

Background and objectives Many research studies show that self-stigma related to weight can exacerbate mental health issues. There is also evidence suggesting that depression, anxiety, and stress could be predictors of weight stigma. However, these connections have not been thoroughly investigated among young people in Saudi Arabia, where there is a high prevalence of obesity. This study aimed to explore the relationships between depression, anxiety, stress, and weight self-stigma in Saudi Arabian adolescents and young adults. Materials and methods This cross-sectional study was conducted between January and March 2022 and utilized online surveys, including the Weight Self-Stigma Questionnaire (WSSQ) and Depression, Anxiety, and Stress Scale 21 (DASS-21). We conducted descriptive analysis, independent samples t-tests, analysis of variance (ANOVA), and linear regression for the statistical analysis using SPSS version 25 (IBM Corp., Armonk, NY). Results A total of 1624 participants were enrolled in this survey. Most participants (889, 54.7%) were females. The mean age was 20.73 years (SD: 2.63). Males were more likely to report self-stigma compared to females (p = 0.018). Weight self-stigma demonstrated significant positive associations with body mass index (BMI) (p = 0.0001) and depression, anxiety, and stress (p = 0.0001) scores. Further analysis revealed weight self-stigma was positively correlated with psychological distress levels in the study population (p = 0.0001). The results demonstrated a statistically significant difference between different regions of Saudi Arabia with weight self-stigma being more prevalent in the Al-Baha region and least prevalent in the Al-Madinah region. Conclusions The results of this study indicate robust positive correlations between weight self-stigma scores and depression, anxiety, and stress scale scores among adolescents and young adults in Saudi Arabia. Further epidemiological and clinical studies on the national level are warranted.

Warfarin and bisphosphontes interaction in patients undergoing total knee arthroplasty.

Background: Patients undergoing knee arthroplasty (TKA) surgery need anticoagulant therapy, mainly warfarin for prevention of venous thromboembolism (VTE). Warfarin is mainly eliminated by renal glomerular filtration where 92 % of warfarin is excreted in urine. Warfarin overdose may lead to significant bleeding and warfarin underdosing may cause VTE and other complications. Thus, international normalized ratio (INR) monitoring is crucial in TKA patients taking warfarin. Great interest has been expressed in bisphosphonate to reduce periprosthetic osteoporosis in patients undergoing total joint arthroplasty. Many human case reports and cohort studies proved bisphosphonates induced impaired renal function. Objectives: The main goal of the current study is to examine the pharmacodynamin effect of bisphosphonates on warfarin excretion and clinical effects in patients undergoing TKA surgery. Methods: Fifty patients undergoing TKA were recruited in the current study. Twenty five patients were given warfarin and twenty five patients were given warfarin and bisphosphonates starting three days after surgery. INR, major bleeding events and minor bleeding events were followed up in all recruited patients for one month after surgery. Results: warfarin plus zoledronic acid group had significantly higher percent of post INR greater than 4 (p = 0.022) and significantly higher percent of minor bleeding events (p = 0.041) than warfarin only group. Conclusion: Concomitant administration of bisphosphonates may increase warfarin bleeding adverse effects in elderly patient undergoing TKA.

A 51-Year-Old Woman with Advanced Peritoneal Mesothelioma and Stage 3b Chronic Kidney Disease Treated with Cytoreductive Surgery and Bidirectional Intraperitoneal Cisplatin and Ifosfamide Chemotherapy: A Case Report.

BACKGROUND Malignant mesotheliomas are rare, yet highly malignant tumors. Mesotheliomas are tumors that develop from mesothelial surfaces, with the pleura being the most common, followed by the peritoneum. The diagnosis of malignant peritoneal mesothelioma (MPM) is usually established when the disease is advanced, owing to the nonspecific clinical appearance and abdominal symptoms. Initially, MPM was treated with palliative systemic chemotherapy, with or without palliative surgery. However, cytoreductive surgery (CRS) combined with bidirectional intraoperative chemotherapy (BDIC) has recently emerged as a treatment option for MPM. BDIC creates a bidirectional chemotherapy gradient in the peritoneal tumor cells through the simultaneous use of intraperitoneal and intravenous chemotherapy. CRS, combined with BDIC (CRS-BDIC), allows the complete elimination of residual tiny tumor cells after complete removal of the visible tumor nodules. CASE REPORT Herein, we present a case of a 51-year-old woman with MPM and chronic kidney disease (CKD) stage 3b. Her treatment consisted of neoadjuvant chemotherapy and immunotherapy, followed by CRS-BDIC using intraperitoneal cisplatin and doxorubicin, and intravenous ifosfamide. The surgery was successful, with no immediate complications or decline in the patient's kidney function. On follow up 2 months later, the patient denies suffering any chemotherapy-related adverse effects, and her kidney profile remains stable. CONCLUSIONS In conclusion, nephrotoxicity, a known adverse effect of cisplatin and ifosfamide, might not be a contraindication for the use of these potentially nephrotoxic drugs in CRS-BDIC in patients with renal impairment.

Comprehensive Transcriptome Analysis Reveals the Distinct Gene Expression Patterns of Tumor Microenvironment in HPV-Associated and HPV-Non Associated Tonsillar Squamous Cell Carcinoma.

Head and neck squamous cell carcinomas (HNSCCs) are a common type of cancer, ranking as the sixth most prevalent cancer worldwide and having a high morbidity and mortality rate. Among oropharyngeal squamous cell carcinoma (OPSCC) cancers, tonsillar squamous cell carcinoma (TSCC) is the most prevalent and has a particularly aggressive clinical course with poor disease outcomes. The tumor microenvironment (TME) of HNSCC is complex and heterogeneous, playing a crucial role in effective cancer therapy. Understanding the interaction between cancer inflammation, immunity, oncogenes, and tumor suppressor genes is essential for developing effective cancer treatments. This study aimed to gain a comprehensive understanding of the transcriptomes of the TME in TSCC, both associated with human papillomavirus (HPV) and not associated with HPV. The gene expression profiles of 168 genes linked to various cellular mediators and factors involved in inflammation, immunity crosstalk, transcription, signal transduction, oncogenesis, tumor suppression, angiogenesis, and apoptosis were analyzed. We identified 40 differentially expressed genes related to the communication between tumor cells and the cellular mediators of inflammation and immunity crosstalk. In HPV-positive TSCC patients, 33 genes were over-expressed with a fold change greater than 1.5, and 26 of these genes were unique to this group. In contrast, HPV-negative TSCC patients had 11 up-regulated genes. The results further showed that 48 gene transcripts related to oncogenesis, tumor suppression, angiogenesis, and apoptosis were up-regulated in both HPV-positive and HPV-negative TSCC patients. Among the HPV-positive TSCC patients, 37 genes were over-expressed, while the HPV-negative TSCC patients had 11 up-regulated genes. The tumor microenvironment (TME) of HPV-associated and HPV-non-associated TSCC exhibited distinct characteristics, including the dysregulation of various genes involved in cellular mediators, inflammation, immunity crosstalk, transcription factors, immune signaling pathways, signal transduction, oncogenesis, tumor suppression, angiogenesis, and apoptosis. Additionally, we detected six Hr-HPV genotypes in 81% of the TSCC patients, with HPV-16 and HPV-35 being the most common types, followed by HPV-45 and HPV-18. HPV-39 and 31 were also identified. The presence of Hr-HPV genotypes in TSCC patients varied from single to multiple infections. In conclusion, we observed distinct heterogeneity in the transcriptome of the microenvironment in HPV-associated and non-associated TSCC. Further in vitro and in vivo studies are needed to investigate the functional implications of the identified over-expressed genes. Also, deeper molecular pathways and immunological studies on the TME are required to determine the potential of targeting genes for cancer therapy.

Awareness of Hernias and Their Risk Factors Among Adults in the Western Region of Saudi Arabia.

Objective To assess the awareness of hernia and its risk factors among adults in the western region of Saudi Arabia. Our hypothesis was that the studied population was in need of education regarding this matter.  Methods This cross-sectional study was conducted in the western region of Saudi Arabia from November to December 2022, using a Google form. The generated questionnaire consisting of two parts was distributed electronically through social media platforms. The targeted population included adults from the western region of Saudi Arabia. The data were obtained using Microsoft Excel and analyzed using Statistical Package for Social Sciences (SPSS) v. 26 software (IBM Corp., Armonk, NY). Results A total of 1570 adults from the western region of Saudi Arabia were included in our study. We found that 13% of the participants had good overall knowledge about hernia, 31% had poor knowledge, and 56% had moderate knowledge. Alarmingly, 55% of the participants had a poor attitude, and 27% were evaluated as having poor practice. In addition, we found a significant association between people's level of knowledge and multiple factors, including age (p-value < 0.001), marital status (p-value< 0.001), and occupation (p-value< 0.001).  Conclusion Based on our research, more than half of our population had a moderate level of knowledge regarding hernias including their risk factors and complications, with alarming levels of poor attitudes toward the disease. Healthcare workers were our participants' leading source of medical information, which directs us towards fully equipping them with the knowledge to educate the public effectively.

Calpain signaling: from biology to therapeutic opportunities in neurodegenerative disorders.

Neurodegenerative disorders represent a major and growing healthcare challenge globally. Among the numerous molecular pathways implicated in their pathogenesis, calpain signaling has emerged as a crucial player in neuronal dysfunction and cell death. Calpain is a family of calcium-dependent cysteine proteases that is involved in many biological processes, such as signal transduction, cytoskeleton remodeling, and protein turnover. Dysregulation of calpain activation and activity has been associated with several neurodegenerative diseases, including Alzheimer's, Parkinson's, and Huntington's diseases. Understanding the intricate structure of calpains is crucial for unraveling their roles in cellular physiology and their implications in pathology. In addition, the identification of diverse abnormalities in both humans and other animal models with deficiencies in calpain highlights the significant progress made in understanding calpain biology. In this comprehensive review, we delve into the recent roles attributed to calpains and provide an overview of the mechanisms that govern their activity during the progression of neurodegenerative diseases. The possibility of utilizing calpain inhibition as a potential therapeutic approach for treating neuronal dysfunctions in neurodegenerative disorders would be an area of interest in future calpain research.

Is the Hartmann's procedure for diverticulitis obsolete? National trends in colectomy for diverticulitis in the emergency setting from 1993 to 2018.

BACKGROUND: Historically, Hartmann's procedure (HP) has been the operation of choice for diverticulitis in the emergency setting. However, recent evidence has demonstrated the safety of primary anastomosis (PA) with or without diverting ileostomy. The purpose of this study was to evaluate the trends of, and factors associated with, HP compared to PA in emergency surgery for diverticulitis over 25 years. METHODS: Using the National Inpatient Sample database, we identified adult patients ≥ 18 years old who underwent emergency surgery for diverticulitis (HP or PA) between 1993 and 2018 using ICD-9 and ICD-10 codes. Patients with inflammatory bowel disease, gastrointestinal cancer or who underwent elective diverticulitis surgery were excluded. Trends in HP were analyzed using multivariable linear regression, and factors associated with HP were assessed with multiple logistic regression. RESULTS: Of 499,433 patients who underwent colectomy in the emergency setting for acute diverticulitis, 271,288 (54.3%) had a HP and 228,145 (45.7%) had a PA. Median age was 61 years (IQR: 50-73), 53% were women, and 70.5% were white. The proportion of HP slightly increased over the study period-HP comprised 52.6% of included cases in 1993-98 and 55.2% of cases in 2014-2018 (p = 0.017). Advanced age (reference = 18-44 years; 45-54 years: OR 1.16, 95% CI 1.10-1.22; 55-64 years: OR 1.26, 95% CI 1.20-1.33; 65-74 years: OR 1.33, 95% CI 1.25-1.42; ≥ 75 years: OR 1.51, 95% CI 1.41-1.62), complicated diverticulitis (OR 1.41, 95% CI 1.36-1.46), and severity of illness (reference = minor; moderate: OR 1.46, 95% CI 1.38-1.54; major/extreme: OR 3.43, 95% CI 3.25-3.63) were associated with increased odds of HP. CONCLUSIONS: Over a 26-year period, HP has remained the most performed procedure in the emergency setting for diverticulitis. Future work should focus on knowledge translation with a possible change in practice as more randomized controlled trials provide support for PA.

Knowledge on, Attitude Toward, and Practice of Contraceptive Methods Among Females of Reproductive Age in Al-Qunfudah Governorate, Saudi Arabia.

Background One of the main goals of Vision 2030 in Saudi Arabia is to increase the participation rate of Saudi females in the workforce. This adjustment may have a big impact on how they use contraception and increase the tendency to space out their children's births appropriately to help them balance their home and work lives. The purpose of this study was to assess the knowledge on, attitude toward, and practice of contraceptive methods among females of reproductive age (15-49 years) in Al-Qunfudah governorate, Saudi Arabia. Methods A cross-sectional study was carried out among a convenient sample of 400 females of reproductive age in Al-Qunfudah governorate, Saudi Arabia. The necessary data were obtained over a period of two months (from November to December 2022) by using a self-administered online survey that was applied on different electronic platforms. Both knowledge and attitude scores were divided into two categories using the median as a cutoff point (e.g., good knowledge and poor knowledge, as well as positive and negative attitude). Many sociodemographic variables, such as age, residence, and education, were independent variables. Logistic regression analysis was done to determine the magnitude of associations between independent and dependent variables, and the odds ratios (OR) were presented with 95% confidence intervals (CI) at a significance level of P = 0.05. Results Good knowledge of the different contraceptive methods was observed among 69.8% of the females, where contraceptive pills and the intrauterine device (IUD) were the most well-known contraceptive methods to them (85.25% and 57.75%, respectively). Family and friends were their main sources of information (38.75%). Almost 85% of the participants showed a positive attitude toward contraceptive use. Contraceptive pills (32.39%) and IUDs (29.95%) were the most commonly used contraceptive methods. The determinants of good knowledge of contraception were being younger in age (P = 0.01, OR = 0.14, 95% CI = 0.03-0.65) and living in an urban area (P = 0.01, OR = 0.24, 95% CI = 0.09-0.68). Females holding middle or high school educational degrees (P = 0.02, OR = 0.17, 95% CI = 0.04-0.75 and P = 0.03, OR = 0.23, 95% CI = 0.06-0.88, respectively) and having a low monthly income (P = 0.04, OR = 0.44, 95% CI = 0.20-0.96) were likely to have positive attitudes toward contraceptive methods. Conclusion This study concludes that females of reproductive age had satisfactory knowledge and a positive attitude toward various contraceptives; however, there is a big gap in their knowledge regarding two important contraceptive procedures (emergency and permanent contraceptives). Oral contraceptive (OC) pills and IUDs were the most utilized methods of contraception among them. Sustained efforts are needed to raise females' awareness about contraception methods, especially emergency contraceptives and permanent ones. This study was done on a convenient sample of females in reproductive age that may limit the generalization of data; using an online survey has its constraints, such as the ignorance of the illiterate females and those who did not possess internet connections in addition to recall bias; therefore, we recommend further research on this topic through an interactive interview among a random sample of females to overcome such pitfalls.

Awareness of the General Population Toward Constipation and Its Complications in the Western Region, Saudi Arabia.

Background and aim Constipation can be defined as unsatisfying defecation characterized by difficult stool passage, infrequent stools, or both. Complications include hemorrhoids, anal fissures, and prolapse of pelvic organs. Unfortunately, there needs to be more data available regarding awareness on this subject. Thus, in this study, we aim to measure the level of understanding of constipation and its complications in the western region of Saudi Arabia. Methods In this cross-sectional study, a valid and reliable questionnaire was used in data collection. In addition, SPSS (IBM Corp., Armonk, NY) was used for the analysis of collected data. Results The present study included a total of 778 participants from the general public, 75.6% of whom were female and 24.4% of whom were male. We found that 70% of participants had an overall good awareness of constipation, with significant variation in levels of awareness among different groups; levels of awareness increased with age (P-value < 0.001), higher education also positively affected the level of understanding (P-value = 0.04), and participants who reported personal experience had higher levels of awareness than participants who did not have personal experience (P-value​​​​​​​ = 0.002). There was no significant association between the level of awareness and gender or city of residence. Conclusion Much of our population was well aware of constipation and its complications, with significant variation in awareness among different age groups, educational levels, and personal experiences.

Infection transmission via mobile phones in a mass gathering setting: Public knowledge, attitudes and practices in Makkah city, Saudi Arabia.

Background: Mobile phones have become part of everyday life with a potential risk for microbial transmission. Makkah is a mass gathering city that may act as hotspots of disease transmission. The contact between public and both visitors and pilgrims to Makkah can't be overlooked, and any small outbreak within the public can be transmitted rapidly to them. Aim: We aimed to assess knowledge, attitudes, and practices (KAP) of general population towards infection transmission via mobile phones in Makkah and different characteristics relevant to KAP scores. Methods: A cross-sectional web-based survey was conducted on general population in Makkah city using a snowballing sampling method. Participants answered questions about their KAP towards infection transmission via mobile phone. The overall KAP scores were graded as good, fair, and poor and explored against different population characteristics using suitable statistical methods. Results: The study included 385 participants aged 15-64 years. About 88.8% owned personal mobile phone, 3.9% encountering a patient with infections transmitted via mobile phones, and 60.5% know nothing about potential role of mobile phones in infection transmission. Only 16.6% had good knowledge, 64.1% with positive attitudes, and 55.3% reported poor practices. The mean knowledge score was significantly higher among young adults (p = 0.002) and those with higher education (p = 0.005). Their mean attitude and practice scores were significantly higher among older adults (p < 0.001 and p = 0.015), female (p = 0.001 and p = 0.022), and those with higher education (p = 0.036 and p = 0.041) respectively. Conclusion: The overall public knowledge and practices towards the role of mobile phones in infection transmission in Makkah was below average though they have positive attitudes. Raising public awareness is important to decrease the possibility of cross-contamination via mobile phones and to develop adequate preventive strategies in a mass gathering setting like Makkah city.

SBT-272 improves TDP-43 pathology in ALS upper motor neurons by modulating mitochondrial integrity, motility, and function.

Mitochondrial defects are one of the common underlying causes of neuronal vulnerability in neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS), and TDP-43 pathology is the most commonly observed proteinopathy. Disrupted inner mitochondrial membrane (IMM) reported in the upper motor neurons (UMNs) of ALS patients with TDP-43 pathology is recapitulated in the UMNs of well-characterized hTDP-43 mouse model of ALS. The construct validity, such as shared and common cellular pathology in mice and human, offers a unique opportunity to test treatment strategies that may translate to patients. SBT-272 is a well-tolerated brain-penetrant small molecule that stabilizes cardiolipin, a phospholipid found in IMM, thereby restoring mitochondrial structure and respiratory function. We investigated whether SBT-272 can improve IMM structure and health in UMNs diseased with TDP-43 pathology in our well-characterized UMN reporter line for ALS. We found that SBT-272 significantly improved mitochondrial structural integrity and restored mitochondrial motility and function. This led to improved health of diseased UMNs in vitro. In comparison to edaravone and AMX0035, SBT-272 appeared more effective in restoring health of diseased UMNs. Chronic treatment of SBT-272 for sixty days starting at an early symptomatic stage of the disease in vivo led to a significant reduction in astrogliosis, microgliosis, and TDP-43 pathology in the ALS motor cortex. Our results underscore the therapeutic potential of SBT-272, especially within the context of TDP-43 pathology and mitochondrial dysfunction.

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.

Selective Calpain Inhibition Improves Functional and Histopathological Outcomes in a Canine Spinal Cord Injury Model.

Calpain activation has been implicated in various pathologies, including neurodegeneration. Thus, calpain inhibition could effectively prevent spinal cord injury (SCI) associated with neurodegeneration. In the current study, a dog SCI model was used to evaluate the therapeutic potential of a selective calpain inhibitor (PD150606) in combination with methylprednisolone sodium succinate (MPSS) as an anti-inflammatory drug. SCI was experimentally induced in sixteen mongrel dogs through an epidural balloon compression technique. The dogs were allocated randomly into four groups: control, MPSS, PD150606, and MPSS+PD150606. Clinical evaluation, serum biochemical, somatosensory evoked potentials, histopathological, and immunoblotting analyses were performed to assess treated dogs during the study. The current findings revealed that the combined administration of MPSS+PD150606 demonstrated considerably lower neuronal loss and microglial cell infiltration than the other groups, with a significant improvement in the locomotor score. The increased levels of inflammatory markers (GFAP and CD11) and calcium-binding proteins (Iba1 and S100) were significantly reduced in the combination group and to a lesser extent in MPSS or PD150606 treatment alone. Interestingly, the combined treatment effectively inhibited the calpain-induced cleavage of p35, limited cdk5 activation, and inhibited tau phosphorylation. These results suggest that early MPSS+PD150606 therapy after acute SCI may prevent subsequent neurodegeneration via calpain inhibition.
