A Rare Case of Gastric Phytobezoar (Diospyrobezoar) in a Healthy Adult.

Phytobezoars are solid masses of indigestible plant material and are a common type of gastrointestinal bezoar, with varying incidences globally. These bezoars typically form from the ingestion of high-fiber fruits and vegetables and are associated with factors such as decreased gastric acid production and delayed gastric emptying. We present a case of a 35-year-old healthy man with recurrent upper abdominal pain, nausea, a rolling ball sensation in the abdominal region, and a history of consuming unripe persimmons. Imaging revealed the presence of phytobezoars in the stomach, leading to unsuccessful endoscopic attempts at removal. Laparoscopic extraction was eventually performed successfully after failed conservative management. The case highlights the rarity of diospyrobezoars, a subtype of phytobezoars formed from persimmon ingestion, and the challenges in their management. Surgical intervention, particularly laparoscopic extraction, can be effective but carries risks such as surgical site infections. Comprehensive care involving diagnostic imaging, non-surgical interventions, and surgical techniques is crucial for the successful management of phytobezoars. Phytobezoars, though relatively common, present unique diagnostic and management challenges, especially when formed from specific dietary factors such as persimmons. Understanding their epidemiology, clinical manifestations, and treatment options, including the role of laparoscopic surgery, is essential for optimizing patient outcomes and minimizing complications such as surgical site infections.

Burnout and resilience among physical therapy students: a cross-sectional study.

BACKGROUND: This study aimed to examine the prevalence of burnout, determine burnout-related factors, investigate resilience levels, and assess the relationship between burnout and resilience among physical therapy (PT) students at King Saud University (KSU) in Saudi Arabia. MATERIAL AND METHODS: This cross-sectional study involved 153 PT students studying at KSU between January and March 2023. The participants completed an online questionnaire, a Maslach Burnout Inventory, and a Brief Resilience Scale. RESULTS: Low-to-moderate levels of Emotional Exhaustion (EE) were observed in 85% of the participants and high Depersonalization (DP) levels were reported by 34.2%. Female participants reported higher levels of EE and DP, whereas males had a greater prevalence of low Personal Achievement (PA) levels. Approximately 6.5% of the study participants reported high burnout levels (a combination of high DP, high EE, and low PA). Academic stress, followed by sleeping difficulties and changes in the academic year structure, were the most important factors contributing to higher levels of burnout (75.2%, 56.9%, and 43.8%, respectively). Most study participants around (66.0%) reported normal resilience levels. A significant correlation was detected between resilience and 2 domains of burnout (DP and PA), with the correlation being negative and weak for DP and positive and moderate for PA. CONCLUSIONS: Overall, low-to-moderate levels of burnout were observed among the PT students who took part. Related factors that contributed to burnout were academic stress, sleeping difficulties, and academic year structure. A normal level of resilience was found to be significantly related to DP and PA but not to EE on the burnout subscales. Higher levels of resilience can be considered to play a protective role against burnout among PT students. Med Pr Work Health Saf. 2024;75(4):343-354.

Exploring Patient Preferences for Information About CT Radiation Exposure: Bridging the Gap Between Patient Preference and Physician Practice.

Background: CT scan utilizes ionizing radiation poses a danger to the patient's health. Thus, telling the patient about ionizing radiation would be critical in promoting shared decision-making and improving patient-doctor communication. However, few studies have examined this topic broadly. Objective: The study was conducted to identify the frequency of physicians informing patients about the radiation risk before ordering a CT scan, as well as to examine the association between patients' demographic characteristics and their awareness of the radiation risks associated with CT scans. Methods: A cross-sectional study was conducted among 387 patients who had undergone CT scans at a tertiary hospital in Riyadh, Saudi Arabia. Data were collected via phone interviews using a structured questionnaire. Chi-squared tests were employed to assess associations between patients' demographic characteristics and their awareness of CT scan radiation risks. Results: When examining knowledge, 58% of patients knew that CT involves harmful radiation. This knowledge was significantly associated with higher education level and previous experience with CT scans. Regarding doctors' practice of providing information to patients about the scan, 344 (88.9%) patients indicated that their doctor had explained to them why they needed the scan. Only 28 (7.2%) patients stated that their doctor had mentioned the amount of radiation, and 74 (19.1%) patients indicated that doctors mentioned the risks associated with the radiation of the scan. Almost all patients (96.9%) preferred to be told about why they needed a CT scan. Conclusion: The vast majority of patients who underwent CT scans did not receive enough information about the harm of the scans. However, most of them preferred to know about this harm.

Diabetes was the most prevalent (21.3%, n=48) among participants. Doctors were the primary source of health advice (46.2%, n=104). Structural aspects received high satisfaction (mean score of 31.8), surpassing healthcare provider delivery (mean score of 24.9) and print materials (mean score of 22.7). Demographically, occupation significantly impacted contentment (p-value=0.002), with students exhibiting the highest scores. Logistic regression highlighted patients' occupation (aOR=1.498) and patients' level of education (aOR=0.420) as predictors of contentment. CONCLUSION: This study highlighted high satisfaction with structural aspects of health education. Occupation, particularly among students, significantly impacts contentment. Tailoring education strategies based on occupation and education levels is crucial for improved patient satisfaction.

The Impact of Bariatric Surgery on Weight Reduction and the Resolution of Comorbidities in Older Geriatric Populations of Saudi Arabia: A Retrospective Study.

Background Obesity is a significant health concern among older adults, leading to various comorbidities and reduced quality of life. Bariatric surgery (BS) has emerged as a potential intervention, but its efficacy in geriatric populations, particularly in Saudi Arabia, is not well-established. Aims This retrospective study aims to evaluate the impact of BS on weight reduction and comorbidity resolution in Saudi Arabian geriatric populations. Methods A retrospective cohort study was conducted at King Khalid Hospital, Saudi Arabia, involving geriatric patients aged 60 and above who underwent BS between January 2018 and December 2022. Data were collected from medical records and analyzed using descriptive statistics, chi-square tests, t-tests, and multivariate regression analysis. Results The study included a total of 26 patients with a mean age of 64 years. Of these, 18 (69.3%) were females, while eight (30.7%) were males, and 23 (87%) underwent sleeve gastrectomy (SG), while three (13%) had Roux-en-Y gastric bypass (RYGB). Preoperative comorbidities majorly included diabetes (17, 35.42%), hypertension (11, 22.92%), and anemia (four, 8.33%). The average body mass index (BMI) of the patients decreased significantly from 45.12 to 37.29 at three months and further to 31.36 at six months post surgery. Total weight loss (TWL) was 19.92% at three months and 35.15% at six months, while the percentage of excess weight loss (%EWL) was 33.42% at three months and 57.85% at six months. Results also showed a significant reduction in the number of comorbidities postoperatively. A significant association with gender, preoperative weight, and preoperative height at three and six months and a significant association with preoperative BMI and comorbidity status at six months were recorded. Conclusion The study suggests that bariatric surgery is effective in achieving significant weight loss and improving comorbidities in geriatric patients. Few demographic and clinical features affect the outcome of the weight loss.

Essential oils as capsule disruptors: enhancing antibiotic efficacy against multidrug-resistant Klebsiella pneumoniae.

Background: Multidrug-resistant Klebsiella pneumoniae (MDR-KP) poses a significant global health threat due to its involvement in severe infections and high mortality rates. The emergence of MDR strains necessitates the exploration of alternative therapeutic strategies. Methods: K. pneumoniae isolates were obtained from human and animal sources. Antibacterial susceptibility testing was performed, followed by the evaluation of essential oil activity through inhibition zone, MIC, and MBC determinations. Checkerboard assays were conducted to assess synergistic effects with amikacin. Gene expression analysis and transmission electron microscopy were employed to elucidate the mechanisms of action. Molecular docking studies were performed to identify potential binding targets of bioactive compounds. Results: Klebsiella pneumoniae was isolated from 25 of the100 samples examined, representing a prevalence rate of 25%. All isolates were found to be multidrug-resistant. Tea tree and thyme essential oils exhibited potent antibacterial activity and synergistic effects with amikacin. Notably, these combinations significantly downregulated the expression of key capsule virulence genes (wcaG, rmpA, magA, uge, and wabG), suggesting a novel mechanism for enhancing amikacin efficacy. Transmission electron microscopy revealed disrupted cell integrity in MDR-KP cells treated with the combinations. Molecular docking analysis identified Terpinen-4-ol, Farnesol, 1,4-Dihydroxy-p-menth-2-ene, and 7-Oxabicyclo [4.1.0] heptane as potential bioactive compounds responsible for the observed effects. Conclusion: By effectively combating MDR-KP, this research holds promise for reducing antibiotic resistance, improving treatment outcomes, and ultimately enhancing potential care.

Safety and Effectiveness of Direct Oral Anticoagulants Versus Warfarin in Patients with Venous Thromboembolism using Real-World Data: A Systematic Review and Meta-Analysis.

BACKGROUND: Direct oral anticoagulants (DOACs) have shown comparable efficacy and a superior safety profile in clinical trials for patients with venous thromboembolism (VTE). However, further study is needed to assess DOACs' effectiveness and safety compared to warfarin in a real-world context. Thus, this meta-analysis compares the effectiveness and safety of warfarin and DOACs in patients with VTE. METHOD: A systematic review of the literature using PubMed and EMBASE was conducted from inception until June 2024. We examined observational studies that compared safety and effectiveness between DOACs and warfarin when used in treating VTE and reported adjusted hazard ratios (HRs) and/or odds ratios (ORs) for recurrent VTE, major bleeding, clinically relevant non-major bleeding, gastrointestinal bleeding, intracranial hemorrhage, and death from any cause. We then estimated the pooled effect using the random-effects model for meta-analysis. RESULTS: A total of 25 studies were included in the current meta-analysis. DOAC therapy was associated with significantly lower risks of recurrent VTE (HR 0.76, 95% confidence interval [CI] 0.69-0.85), major bleeding (HR 0.77, 95% CI 0.72-0.83), clinically relevant non-major bleeding (HR 0.82, 95% CI 0.77-0.88), and gastrointestinal bleeding (HR 0.75, 95% CI 0.68-0.83) compared to warfarin. However, no statistically significant difference was observed in all-cause mortality between the two groups (HR 0.96, 95% CI 0.83-1.10). CONCLUSION: This meta-analysis found that DOACs are associated with a significant reduction in VTE recurrence in addition to the known favorable safety profile when compared to warfarin.

Putting patients at the center of health information exchange design: An exploration of patient preferences for data sharing.

BACKGROUND: Despite the many benefits of Health Information Exchange (HIE), Studies reported patients concerns about the privacy and security of sharing their health information. To address these concerns, it is important to understand their needs, preferences, and priorities in the design and implementing HIE systems. OBJECTIVE: The aim of this study is to investigate patients' preferences for HIE consent option and examine the extent to which they are comfortable sharing the different parts of their medical records. METHOD: A self-administered survey was conducted. The survey was administrated online and the total number of respondents was 660 participants. RESULTS: The most popular option selected by participants for sharing HIE information was to share information with their permission once when they register (33.3%) followed by the option to share their information temporarily on demand during their clinical visit (23.8%). The types of information which participants were willing to share the most were general data such as age, weight, height, and gender, followed closely by data needed for medical emergency. In contrast, the information which participants were less likely to share were data related to financial status or income, followed by data related to sexual disease, and mental illnesses.

Genetic and Epigenetic Biomarkers Associated with Early Relapse in Pediatric Acute Lymphoblastic Leukemia: A Focused Bioinformatics Study on DNA-Repair Genes.

Genomic instability is one of the main drivers of tumorigenesis and the development of hematological malignancies. Cancer cells can remedy chemotherapeutic-induced DNA damage by upregulating DNA-repair genes and ultimately inducing therapy resistance. Nevertheless, the association between the DNA-repair genes, drug resistance, and disease relapse has not been well characterized in acute lymphoblastic leukemia (ALL). This study aimed to explore the role of the DNA-repair machinery and the molecular mechanisms by which it is regulated in early- and late-relapsing pediatric ALL patients. We performed secondary data analysis on the Therapeutically Applicable Research to Generate Effective Treatments (TARGET)-ALL expansion phase II trial of 198 relapsed pediatric precursor B-cell ALL. Comprehensive genetic and epigenetic investigations of 147 DNA-repair genes were conducted in the study. Gene expression was assessed using Microarray and RNA-sequencing platforms. Genomic alternations, methylation status, and miRNA transcriptome were investigated for the candidate DNA-repair genes. We identified three DNA-repair genes, ALKBH3, NHEJ1, and PARP1, that were upregulated in early relapsers compared to late relapsers (p < 0.05). Such upregulation at diagnosis was significantly associated with disease-free survival and overall survival in precursor-B-ALL (p < 0.05). Moreover, PARP1 upregulation accompanied a significant downregulation of its targeting miRNA, miR-1301-3p (p = 0.0152), which was strongly linked with poorer disease-free and overall survivals. Upregulation of DNA-repair genes, PARP1 in particular, increases the likelihood of early relapse of precursor-B-ALL in children. The observation that PARP1 was upregulated in early relapsers relative to late relapsers might serve as a valid rationale for proposing alternative treatment approaches, such as using PARP inhibitors with chemotherapy.

From Likes to Lifestyle: Predicting the Impact of Following Fitness Influencers on the Adoption of Healthy Habits in Saudi Arabia.

BACKGROUND:  The increasing popularity of fitness influencers on social media has the potential to significantly impact public health by promoting healthy behaviors. Understanding how these influencers affect the adoption of healthy habits among Saudi residents can provide insights into effective public health strategies. OBJECTIVE:  This study aims to quantitatively assess the influence of following fitness influencers on social media on adopting healthy behaviors among Saudi residents, focusing on socio-demographic factors, characteristics of influencers, and participants' perceptions. METHODS:  A descriptive, cross-sectional study with an analytical component was carried out from March 25, 2023, to August 15, 2023. The study included Saudi residents aged 18 and older who actively follow fitness influencers. Data was gathered through an online questionnaire and analyzed using descriptive statistics, Pearson's chi-square test, and logistic regression analyses to identify factors associated with positive health outcomes. RESULTS:  The study included 561 participants, revealing that marital status and residential region significantly influenced the adoption of healthy habits, with married participants and those from the Southern and Central regions more likely to report positive outcomes. Notably, engagement in physical activity more than three times a week and adherence to a healthy diet were strongly associated with positive health outcomes (p<0.05). Analysis of influencer characteristics showed that following fewer than 10 influencers and being unaware of their follower count were predictors of positive results with p<0.05. Specifically, 76.6% of participants experienced positive results after following health advice from social media, highlighting the impactful yet complex role of influencers in shaping health behaviors. Logistic regression analyses underscored the significance of socio-demographic factors, influencer characteristics, and participant perceptions in predicting the likelihood of experiencing positive health outcomes. CONCLUSION:  Following fitness influencers on social media can positively impact the adoption of healthy habits, moderated by socio-demographic factors and influencer characteristics.

Most participants resided in urban areas n=366 (79.4%) with their parents n=230 (49.9%). The prevalence of inguinal hernias in adults was low (5.2%). Our results indicated a significant association between family history of inguinal hernia, chronic cough, bronchial asthma, smoking, and inguinal hernia (p < 0.001). Young adults and undergraduates displayed significantly low awareness of inguinal hernias (p < 0.001). CONCLUSION: Family history of inguinal hernia, chronic cough, bronchial asthma, and smoking were factors associated with inguinal hernia. Low awareness levels were observed among young undergraduates, with a moderate overall level of awareness.

Comprehensive analysis of malabar tamarind fruit rind total extract: HPTLC fingerprinting, in-silico exploration of its metabolites for SARS-cov-2 omicron spike protein, antibacterial and antidiabetic potentials with in vitro evaluation of antidiabetic and antioxidant activities.

Malabar tamarind tropical fruit, scientifically known as Garcinia gummi-gutta, is indigenous to Southeast Asia. In this work, the total methanolic extract of the Malabar fruit rind was examined by HPTLC fingerprinting, with quantitative evaluation of the total phenolics and flavonoids. Library of previously reported natural metabolites was utilized to demonstrate their affinity for specific target sites, they were evaluated against Omicron SARS-CoV-2 mainly it's Spike Protein, bacterial tyrosinase, and antidiabetic targets such α-glucosidase, pancreatic lipase and also α-amylase enzymes. The molecular docking revealed that the Guttiferone R possessed the highest binding affinity toward the Omicron Spike Protein with a stable binding mode, -8.67 kcal/mol binding energy and a 1.07 Å RMSD value compared to reference, Azithromycin, which has -8.90 kcal/mol binding affinity and a 1.20 Å RMSD value. On the other hand, the identified polyphenolic compounds; Vitexin, Prunin, Naringin, Hinokiflavone, Kaempherol-3-O-rutinoside, Gallic acid, Naringenin, and Catechin, showed remarkable antidiabetic activity by strong inhibitory activity against α-glucosidase and notable activity against α-amylase compared with acarbose as reference. According to antibacterial activity, the identified compounds showed low affinity with weak activity against screened bacterial strains. In-vitro evaluation of Tamarind antioxidant and antidiabetic potentials, it exhibited a free radical-scavenging potential with 71.75 % retardation and α-glucosidase, α-amylase and pancreatic lipase inhibitor activities with an IC50 of 391.3 ± 26.27, 95.03 ± 0.03 and 0.01043 ± 0.0004 µg/mL, respectively that emphasize the molecular docking study. The findings imply that Malabar tamarind fruit rind possess antioxidant, antidiabetic, antibacterial and antiviral activities.

Leveraging machine learning to enhance postoperative risk assessment in coronary artery bypass grafting patients with unprotected left main disease - A retrospective cohort study.

BACKGROUND: Risk stratification for patients undergoing coronary artery bypass surgery (CABG) for left main coronary artery (LMCA) disease is essential for informed decision-making. This study explored the potential of machine learning (ML) methods to identify key risk factors associated with mortality in this patient group. METHODS: This retrospective cohort study was conducted on 866 patients from the Gulf Left Main Registry who presented between 2015 and 2019. The study outcome was hospital all-cause mortality. Various machine learning models [logistic regression, random forest (RF), k-nearest neighbor, support vector machine, naïve Bayes, multilayer perception, boosting] were used to predict mortality, and their performance was measured using accuracy, precision, recall, F1 score, and area under the receiver operator characteristic curve (AUC). RESULTS: Nonsurvivors had significantly greater EuroSCORE II values (1.84 (10.08-3.67) vs. 4.75 (2.54-9.53) %, P<0.001 for survivors and nonsurvivors, respectively). The EuroSCORE II score significantly predicted hospital mortality (OR: 1.13 (95% confidence interval: 1.09-1.18), P<0.001), with an AUC of 0.736. RF achieved the best ML performance (accuracy=98, precision=100, recall=97 and F1 score=98). Explainable artificial intelligence using SHAP demonstrated the most important features as follows: preoperative lactate level, emergency surgery, chronic kidney disease (CKD), NSTEMI, nonsmoking status, and sex. QLattice identified lactate and CKD as the most important factors for predicting hospital mortality this patient group. CONCLUSION: This study demonstrates the potential of ML, particularly the Random Forest, to accurately predict hospital mortality in patients undergoing CABG for LMCA disease and its superiority over traditional methods. The key risk factors identified, including preoperative lactate levels, emergency surgery, chronic kidney disease, NSTEMI, nonsmoking status, and sex, provide valuable insights for risk stratification and informed decision-making in this high-risk patient population. Additionally, incorporating newly identified risk factors into future risk scoring systems can further improve mortality prediction accuracy.

The Pathological Pattern of Breast Cancer in the Najran Region of Saudi Arabia: A Retrospective Study.

Background Breast cancer (BC) is the most widespread cancer on a global scale, and its prevalence is likewise significant in the Kingdom of Saudi Arabia. Nevertheless, the data accessible regarding the epidemiology and histopathological characteristics of BC in clinical practice is restricted and primarily confined to research endeavors. Aim This study aims to investigate the histopathological profile of women diagnosed with BC seeking treatment at King Khalid Hospital in the Najran region of the Kingdom of Saudi Arabia. Methods In this retrospective study, BC biopsies performed on Saudi patients at King Khalid Hospital between January 2018 and December 2022 were examined. All records of breast biopsies from this timeframe were extracted from the hospital's histopathology laboratory computer database after written permission from the head of the laboratory department. For all neoplastic lesions, the World Health Organization's 2012 categorization of breast tumors was applied. Results A total of 61 women with BC were included. Women's age ranged from 30 to 89 years, with a mean age of 49.6 ± 12.3 years. The most reported BC was invasive ductal carcinoma (IDC; 70.5%). Other types reported included invasive papillary carcinoma (8.2%), ductal carcinoma in situ (4.9%), and invasive lobular carcinoma (3.3%). A total of 14 (23%) of the study women had multifocal cancer. Ki-67 was high in 19 cases (31.1%); six (9.8%) had BRCA1 mutations, and six (9.8%) had BRCA2 mutations. Conclusion The current study revealed that BC was frequent among young females, mainly IDC, which was reported on both sides at different sizes and grades. Breast lump was the most commonly presented symptom and had a high representation in women with hormonal receptors, mainly estrogen receptors, but positive genetic testing was infrequent.
