Exploring Renal Malignancies in Saudi Arabia: Insights from a Tertiary Care Center Study.

This retrospective study aims to describe the characteristics of renal cell carcinoma (RCC) in Saudi Arabia, in terms of epidemiology, clinical presentation, tumor subtype, Fuhrman grade, tumor size and stage, and overall survival. A total of 431 adult patients with a histopathological diagnosis of RCC between 2015 and 2023 were included in the analysis. Most patients (72.4%) had clear cell tumors, followed by chromophobe (15.1%) and papillary (12.5%) subtypes. In males, papillary RCC (85.2%) was more common compared to clear cell (59.8%) and chromophobe (67.7%) subtypes. Significant differences were observed in median body mass index (BMI) across tumor subtypes, and papillary tumor patients exhibited the highest incidence of hematuria (33.3%) compared to other subtypes. The Fuhrman grade also varied significantly among RCC types. Survival times were found to be lower for patients with papillary tumors. No significant difference was observed based on patients' nationality. This study can inform clinical decision-making on patient prognosis and management as well as public health efforts aimed at reducing the alarming rise of RCC incidence.

Preserving Renal Function without Compromising Oncological Outcomes: A Comparative Study of Partial and Total Nephrectomies in T3 Stage Renal Cell Carcinoma.

The utility of partial nephrectomy (PN) in locally advanced, stage T3 renal cell carcinoma (RCC) is controversial. This retrospective study aimed to review the oncological and functional outcomes of patients with T3a RCC who underwent PN. We included all patients with pT3a stage RCC undergoing either open, laparoscopic, or robotic PN at our center between January 2015 and 2023. A Wilcoxon rank sum test was utilized to compare nephrectomy types (radical nephrectomy [RN] vs PN). Survival analysis was conducted using Kaplan-Meier plots and a log-rank test. P-value < 0.05 indicated statistical significance. There were no significant differences in demographic characteristics between the RN and PN groups, except age (53.0 vs 6.5, respectively; P = 0.012) and body mass index (28.7 vs 34.3, respectively; P = 0.020). Furthermore, there were also no significant differences in the rates of local recurrence (P = 0.597), metastatic progression (P = 0.129), and chemotherapy use (P = 0.367) between nephrectomy types. Patient survival did not differ significantly based on the type of nephrectomy (log-rank P-value = 0.852). Together, our findings indicated that PN and RN yield near-equivalent oncological outcomes in terms of local recurrence, metastasis, and overall survival rates among pT3a RCC patients during a nearly 3-year follow-up period.

Public awareness of early symptoms of acute myocardial infarction among Saudi population.

INTRODUCTION: Globally speaking, cardiovascular disease is the leading cause of mortality, with coronary artery disease (CAD) contributing to half of the cases. A major complication of CAD is myocardial infarction (MI). The clinical outcomes of MI are predominantly time-dependent; therefore, it is paramount that the general public is familiar with the early symptoms of MI. AIM: The main objective is to gauge the local public awareness of the early symptoms of MI, and their knowledge of the best course of action to be taken from the onset of symptoms. METHOD: A cross-sectional study was conducted using google forms. Participants were randomly selected through multiple social media platforms. The study included Saudi citizens who were 18 years or older, with no current or prior experience in the health care field. The questionnaire assessed the participants' awareness of 14 risk factors for CAD. The variables investigated were participants' knowledge of the symptoms, causes, appropriate course of action to be taken, and the risk factors of CAD. RESULTS: A total of 1689 participants were involved in this study. Sixty percent were females, and 29.2% were in the age group of 18-24 years. Seventy-three percent of the participants knew the definition of heart attack, and 90% knew that chest pain is a symptom of a heart attack. Approximately, 75% of the participants recognized that hypertension, cigarette smoking, and high cholesterol are the risk factors of MI. In terms of knowledge, Al Madinah province obtained the highest score when compared with other regions. CONCLUSION: This study showed the overall knowledge and awareness of CAD was suboptimal, indicating that awareness initiatives and patient education of CAD need more work in Saudi Arabia, especially in high-risk groups and lower education groups. More studies are needed to identify the efficiency and population access of different approaches for CAD awareness.

The impact of the English medical curriculum on medical history taking from Arabic speaking patients by medical students.

INTRODUCTION: Medical education in Saudi medical colleges is delivered to students through a completely English language curriculum, whereas the practice that students face in the hospital is generally conducted in Arabic language settings. We suggest that the linguistic gap between the adopted medical curriculum and actual practice could influence students' confidence and level of difficulty in history taking in Arabic. The study aimed to identify the effects of learning history taking in the English language on applying it in the medical student's native language. METHODS: This cross-sectional design study was held in the College of Medicine, King Saud Bin Abdulaziz University for Health Sciences (KSAU-HS). The targeted sample size was 377 medical students from the fourth to the sixth year, and stratified random sampling was used. The questionnaire used was self-developed, validated, and pilot tested in other medical colleges. The questionnaire asked about students' confidence, the difficulty of Arabic history taking, and suggested strategies to improve the current curriculum. RESULTS: The response rate was 290 participants (76.9%), males were 205 (71%), and 136 (47%) were in the fourth year. Agreement on feeling confident while taking history taking in Arabic was 98 (33.8%), 102 (35.2%) were neutral, and 90 (31%) disagreed. Moreover, 138 (47.6%) of students preferred training for Objective Structured Clinical Examination (OSCE) in Arabic more than English, 86 (29.7%) were neutral, while 66 (22.8%) disagreed. The mean level of difficulty was 2.1 ± 0.7 (range 1- 5). Additionally, 198 (68%) of students suggested adding short Arabic history courses. CONCLUSION: Students considered history taking in Arabic as easy, even though they were not completely confident. Further efforts are needed to uplift students' of confidence to optimal levels. ADVANCES IN KNOWLEDGE: Communication is the cornerstone of medical education as well as clinical practice. The study explores the impact of instruction language on the physician-patient communication dynamic, providing better infrastructure for evidence-based educational practice. APPLICATION TO PATIENT CARE: This study gives insight into the students' level of preparation to practice in their local community and language. Furthermore, the study addresses strategies to enhance students communication skills and alleviate linguistic barriers in the physician-patient encounter.

The addition of silver nitrate cautery to antiseptic nasal cream for patients with epistaxis: A systematic review and meta-analysis.

OBJECTIVE: To compare the outcomes of the addition of silver nitrate cautery versus antiseptic cream alone in paediatric patients with recurrent epistaxis. METHODS: A systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Guidelines and a search of electronic information was conducted to identify all Randomised Controlled Trials (RCTs) and non-randomised studies comparing the outcomes of the addition of silver nitrate cautery versus antiseptic cream alone in paediatric patients with recurrent epistaxis. Treatment success and persistence of bleeding were primary outcome measures. Secondary outcome measures included treatment side effects. Fixed effects modelling was used for the analysis. RESULTS: Four studies enrolling 240 patients were identified. There was no significant difference between silver nitrate cautery group and antiseptic cream alone group in terms of complete resolution (Odds Ratio [OR] = 1.07, P = 0.81), the partial resolution (OR = 1.02, P = 0.96) and persistence of bleeding (OR = 0.91, P = 0.71). For secondary outcomes, antiseptic nasal cream was associated with few side effects such as rash in one case and several complaints of bad smell or taste. CONCLUSIONS: The addition of silver nitrate cautery is not superior to the use of antiseptic cream alone in paediatric patients with recurrent epistaxis as it does not improve treatment success or persistence of bleeding.

Bacteriostatic and Bactericidal Activities of Camel Lactoferrins Against Salmonella enterica Serovar Typhi.

Lactoferrin is an iron-binding glycoprotein present in various secretions (e.g., milk, tears, saliva, pancreatic juice), which performs multiple functions, with one of them being the antimicrobial defense. Purified camel lactoferrins (cLfs) from different Saudi camel clans, as well as human and bovine lactoferrins (hLf or bLf) were tested as antimicrobial agents against Salmonella enterica serovar Typhi (S. Typhi). All cLfs showed superior antibacterial potentials relative to hLf or bLf, while there was no noticeable difference in the antimicrobial capabilities between the cLfs from different camel clans. We observed synergy between the inhibitory activities of Lfs and antibiotics against bacterial growth. Expression of numerous bacterial proteins was affected by the treatment with Lf and its combinations, giving insight into the molecular mechanisms of the Lf action. Furthermore, several bacterial proteins were shown to interact with cLf-biotin. Scanning and transmission electron microscopy revealed the presence of obvious extracellular and intracellular changes after S. Typhi treatment by antibiotic (carbenicillin) or cLf alone, and in combination. The effects of antibiotics and Lf were synergistic, supporting the potential of the use of Lf-antibiotic combinations.

Synergistic Killing of Pathogenic Escherichia coli Using Camel Lactoferrin from Different Saudi Camel Clans and Various Antibiotics.

Current study aimed to analyze the synergistic killing of pathogenic Escherichia coli using camel lactoferrin from different Saudi camel clans and various antibiotics. Methods: using multiple microbiological and protein analysis techniques, the results were shown that the purified camel lactoferrins (cLfs) from different Saudi camel have strong antimicrobial potentials against two strains of E. coli. Although all cLfs were superior relative to human or bovine lactoferrins (hLf or bLf), there was no noticeable difference in the antimicrobial potentials of cLfs from different camel clans. The effects of antibiotics and cLfs were synergistic, indicating the superiority of using cLf-antibiotic combinations against E. coli growth. Since these combinations possessed distinguished synergy profiles, it is likely that they can be used to enhance the low efficacy of antibiotics, as well as to control the problems associated with bacterial resistance. Furthermore, these combinations can reduce the cost of cure of bacterial infections, especially in the developing countries. The analysis of the molecular mechanisms of lactoferrin action revealed that expression of several E. coli proteins was affected by the treatment with these antibacterial factors. Several proteins of different molecular weights interacting with cLf-biotin were found. Scanning and transmission electron microscopy analysis revealed the presence of noticeable morphological changes associated with the treatment of E. coli strains by antibiotic carbenicillin or cLf alone, and in combination. Camel lactoferrin has superior potential killing of E. coli over bovine and human lactoferrin, and this potential can be further synergistically enhanced of cLF is combined with antibiotics.
