Molecular Characterization, Bioinformatic Analysis, and Expression Profile of Lin-28 Gene and Its Protein from Arabian Camel (Camelus dromedarius).

Lin-28 is an RNA-binding protein that is known for its role in promoting the pluripotency of stem cells. In the present study, Arabian camel Lin-28 (cLin-28) cDNA was identified and analyzed. Full length cLin-28 mRNA was obtained using the reverse transcription polymerase chain reaction (RT-PCR). It was shown to be 715 bp in length, and the open reading frame (ORF) encoded 205 amino acids. The molecular weight and theoretical isoelectric point (pI) of the cLin-28 protein were predicted to be 22.389 kDa and 8.50, respectively. Results from the bioinformatics analysis revealed that cLin-28 has two main domains: an N-terminal cold-shock domain (CSD) and a C-terminal pair of retroviral-type Cysteine3Histidine (CCHC) zinc fingers. Sequence similarity and phylogenetic analysis showed that the cLin-28 protein is grouped together Camelus bactrianus and Bos taurus. Quantitative real-time PCR (qPCR) analysis showed that cLin-28 mRNA is highly expressed in the lung, heart, liver, and esophageal tissues. Peptide mass fingerprint-mass spectrometry (PMF-MS) analysis of the purified cLin-28 protein confirmed the identity of this protein. Comparing the modeled 3D structure of cLin-28 protein with the available protein 3D structure of the human Lin-28 protein confirmed the presence of CSD and retroviral-type CCHC zinc fingers, and high similarities were noted between the two structures by using super secondary structure prediction.

An Orbital Pseudotumor Secondary to Systemic Lupus Erythematosus: A Case Report.

Nonspecific orbital inflammation (NSOI), the primary cause of painful orbitopathy mostly in adults, can either manifest as localized or diffused. Periorbital edema or swelling is the most common sign followed by proptosis. NSOI or orbital pseudomotor secondary to systemic lupus erythematosus (SLE) is very uncommon in the Kingdom of Saudi Arabia. This is the first reported case from Saudi Arabia. The patient first presented to the outpatient department during her gestational period. Her chief complaint was right eye swelling and pain when she woke up in the morning. Her past medical history was positive for irritable bowel disease and SLE. A slit lamp examination revealed chemosis with conjunctival injections in the right eye and mild temporal chemosis in the left eye. Funduscopic examination after pupillary dilation revealed hyperemic discs with venous tortuosity more prominent in the right eye. Serum albumin level was low at 29 g/L. Orbital magnetic resonance imaging without contrast showed bilateral diffuse preseptal soft tissue swelling more prominent on the right side with diffuse bilateral congestion of intraorbital fat, including intraconal and extraconal fat. There was associated fat stranding around the optic nerves bilaterally. The bilateral extraocular muscles showed a diffusely increased T2 signal compatible with edema. The patient was given a bolus of intravenous methylprednisolone for three days. She had a satisfactory recovery. Early diagnosis is important to rule out other differential diagnoses, such as orbital cellulitis and lymphoma.

Clinical Pharmacy Faculty Provision of Direct Patient Care, Challenges, and Opportunities.

Background: The quadripartite mission of clinical track faculty members involves research, teaching, services, and direct patient care. However, the extent of faculty involvement in direct patient care remains a challenge. Thus, the study's objective is to evaluate the effort spent on direct patient care by clinical faculty of pharmacy schools in Saudi Arabia (S.A.) and identify factors that hinder or facilitate providing direct patient care services. Methods: This multi-institutional, cross-sectional questionnaire study conducted between July 2021 and March 2022 involved several pharmacy schools' clinical pharmacy faculty members in S.A. The primary outcome was the percentage of time/effort spent on patient care services and other academic responsibilities. The secondary outcomes were the factors affecting the effort spent on direct patient care and the barriers preventing the provision of clinical services. Results: A total of 44 faculty members took the survey. The percentage of effort spent on clinical education was highest at a median (IQR) of 37.5 (30, 50), followed by that spent on patient care [19 (10, 28.75)]. The percentages of effort spent on education and the length of academic experience were negatively associated with efforts spent on direct patient care. The most commonly reported barrier affecting fulfilling patient care duties was the lack of a clear practice policy (68%). Conclusion: Although most clinical pharmacy faculty members were involved in direct patient care, half of them devoted only 20% or less of their time to it. An effective effort allocation for clinical faculty duties will require the development of a clinical faculty workload model that sets realistic expectations about the time spent on clinical and non-clinical duties.

Prevalence and determinants of community members utilizing preventive services offered by family physicians in Riyadh, Saudi Arabia.

Introduction: Early detection and prevention of diseases can reduce morbidity, mortality, and economic burden. There is need to assess the utilization of preventive services for common chronic diseases, cancers, and vaccinations. This study aimed to estimate the prevalence and sequence of utilization of preventive services for common chronic diseases, cancers, and vaccinations in addition to exploring community perspectives on these services. Materials and Methods: This study was a cross-sectional survey, which was conducted at primary healthcare centers in Prince Sultan Military Medical City covering Riyadh region from October 2022 to January 2023. The study used a self-administered questionnaire to collect data from attendees aged 18 years and older, focusing on the utilization of eight preventive services (blood glucose testing, blood pressure measurement, cholesterol testing, screening for breast cancer, screening for cervical cancer, screening for colorectal cancer, screening for prostate cancer, and flu and pneumococcal vaccines). Descriptive statistics of the study were reported in frequencies and percentages. Chi-square test was used to assess association between outcome variables. Results: Participants were mostly married and had a higher educational degree. However, a considerable number is not accessing primary healthcare services regularly. The results showed that the rate of utilizing preventive services was as follows: blood pressure screening (91%), blood glucose testing (72%), cholesterol testing (65.8%), vaccination utilization (39.5%), breast cancer screening (8%), prostate cancer screening (4.6%), colon cancer screening (4.2%), and least utilized was cervical cancer screening with frequency of (3%). Conclusion: The results underscore the importance of increasing awareness and accessibility of primary healthcare services to promote better health outcomes in the region.

AI-Powered Mental Health Virtual Assistants' Acceptance: An Empirical Study on Influencing Factors Among Generations X, Y, and Z.

STUDY PURPOSE: This study aims to analyze various influencing factors among generations X (Gen X), Y (Gen Y), and Z (Gen Z) of artificial intelligence (AI)-powered mental health virtual assistants. METHODS: A cross-sectional survey design was adopted in this study. The study sample consisted of outpatients diagnosed with various mental health illnesses, such as anxiety, depression, schizophrenia, and behavioral disorders. A survey questionnaire was designed based on the factors (performance expectancy, effort expectancy, social influence, facilitating conditions, and behavioural intention) identified from the unified theory of acceptance and use of the technology model. Ethical approval was received from the Ethics Committee at Imam Abdulrahman Bin Faisal University, Saudi Arabia. RESULTS: A total of 506 patients participated in the study, with over 80% having moderate to high experience in using mental health AI assistants. The ANOVA results for performance expectancy (PE), effort expectancy (EE), social influence (SI), facilitating conditions (FC), and behavioral intentions (BI) indicate that there are statistically significant differences (p < 0.05) between the Gen X, Gen Y, and Gen Z participants. CONCLUSION: The findings underscore the significance of considering generational differences in attitudes and perceptions, with Gen Y and Gen Z demonstrating more positive attitudes and stronger intentions to use AI mental health virtual assistants, while Gen X appears to be more cautious.

Effects of Abstinence Self-Efficacy and Outcome Expectancies of Tobacco Smoking on the Desire to Quit Among Saudi Women: A Cross-Sectional Mediation Analysis.

BACKGROUND: Smoking is one of the major preventable causes of morbidity and mortality and has been associated with numerous illnesses. While smoking is increasing among Saudi women, the characteristics of smoking behavior related to abstinence self-efficacy, which is a belief regarding one's ability to successfully resist performing a behavior, and outcome expectancies, meaning the anticipated consequences of performing a behavior, are unknown. Therefore, this study aimed to test whether abstinence self-efficacy mediated the relationship between tobacco smoking outcome expectancies and the desire to quit tobacco among Saudi women who smoke. METHODS: This cross-sectional study collected a sample of 211 Saudi women who smoked tobacco, including cigarettes and shisha. A self-administered questionnaire was used to examine several variables, including abstinence self-efficacy, outcome expectancies, and desire to quit tobacco smoking. Mediational path analysis was used to answer the research question. Indirect effects were estimated through a bootstrapping of 10,000. RESULTS: All 4 constructs of outcome expectancies (negative consequences, positive reinforcement, negative reinforcement, and appetite/weight control) were associated with lower abstinence self-efficacy and desire to quit tobacco smoking. In the mediation analysis, the indirect effect of negative consequences (standardized beta = -.013, SE = .008, 95% CI [-.030, -.001]), negative reinforcement (standardized beta = -.012, SE = .006, 95% CI [-.025, -.001]), and appetite/weight control (standardized beta = -.008, SE = .006, 95% CI [-.022, -.001]) through abstinence self-efficacy were significant, suggesting mediation in the relationship between outcome expectancies and desire to quit tobacco smoking. CONCLUSION: Cognitive mechanisms that may explain the desire to quit tobacco smoking among Saudi women were identified. Although future longitudinal studies are required to determine relationships prospectively, targeted interventions that correct tobacco smoking outcome expectancies and boost abstinence self-efficacy skills may reduce tobacco smoking among Saudi women.

Short-term improvement of clinical parameters and microbial diversity in periodontitis patients following Indocyanine green-based antimicrobial photodynamic therapy: A randomized single-blind split-mouth cohort.

BACKGROUND: Indocyanine green-mediated photodynamic therapy is effective against chronic periodontitis. Here, we evaluated the efficiency of indocyanine green-based adjunctive antimicrobial photodynamic therapy in non-surgical treatment of chronic periodontitis patients. METHODS: Fifty-six periodontally involved teeth of 20 patients were treated with "scaling and root planing" (control group) or "scaling and root planing with indocyanine green-based (perio-green, 0.1 mg/ml) antimicrobial photodynamic therapy" (test group) using a split-mouth design. We performed clinical assessment of probing depth, gingival recession, clinical attachment loss, and other indices, while plaque samples were collected for microbiome analysis. RESULTS: At baseline, periodontal depth and clinical attachment loss were significantly higher in the test group (p < 0.05), and at 1-month post-treatment, we observed a significant favorable reduction of both periodontal depth and clinical attachment loss in test and control sites, with lower means maintained at 3 months (p = 0.01 and p = 0.000, respectively). Additionally, analysis of variance showed significant improvements in periodontal depth and clinical attachment loss in the indocyanine green-antimicrobial photodynamic therapy group (p = 0.001), although not for clinical attachment loss in controls (p = 0.102). Moreover, a significant reduction was observed in test sites for bleeding on probing and residual pocket post-therapy (p = 0.04 and p = 0.0001 respectively). Furthermore, microbiome analysis identified Porphyromonons gingivalis, Treponema, and Tannerella in all samples with favorable changes in test sites (p = 0.07). CONCLUSION: We observed a significant reduction in periodontal clinical parameters (periodontal depth and clinical attachment loss) in chronic periodontitis patients treated with antimicrobial photodynamic therapy as an adjunctive procedure to conventional scaling and root planing. This improvement was associated with periodontal pathogen reduction and increase in the healthy subgingival microbiome.
