Abstract Introduction The left atrial appendage (LAA) is a distinct structure with unique developmental and structural characteristics. The LAA is involved in the formation of intra-atrial thrombi, particularly in patients with conditions such as atrial fibrillation and mitral valve disease. Left atrial appendage aneurysms (LAAA) are rare abnormal dilations of the LAA that may cause hazardous complications. However, there are limited data on the demographic features, clinical characteristics, management modalities, and prognosis of LAAA patients. This study aimed to conduct a systematic review of the reported cases of LAAA to explore the baseline characteristics, presentation, preferred diagnostic modalities, and optimal management of LAAA. Methods A systematic review was conducted following the PRISMA guidelines. We performed a literature search using MEDLINE/PubMed and Google Scholar. Eligible articles published between January 1940 and November 2022 were included. The eligibility criteria included case reports and case series of LAAA in English language articles. The data extracted included information on the authors, publication year, patient characteristics, signs/symptoms, diagnostic procedures, treatments, and outcomes. Results We identified 177 patients with LAAA in our study. There was a slight female predominance (50.9%), and the mean age was 29.7 years. Palpitations were the most common symptom reported, followed by shortness of breath and thromboembolic events. Transthoracic and transesophageal echocardiograms were the most common modalities for investigating and diagnosing LAAA, and the mean size of the aneurysm was 7.8 (5.7–9.6) × 5.9 (5.0-6.2) cm. Surgical resection is the treatment of choice for most patients with excellent prognoses. Older age and the presence of arrhythmia were significantly associated with thrombus formation and embolic events. Conclusion Left atrial appendage aneurysm is a rare but potentially life-threatening heart pathology that can lead to arrhythmias and thromboembolic events. Surgical resection appears to be the primary treatment option in the current literature, and most patients show improvement or are asymptomatic after treatment. Additionally, alternative approaches, such as transcatheter closure of LAAA, ablation, and medical treatments, have been reported as viable alternatives to surgical intervention.

Abstract Citrobacter koseri causes infection in people who are immunocompromised. Without effective antibiotics, these infections can become severe and life-threatening, so effective drugs are essential to treat these infections. Utilizing subtractive genomics, 2699 ORFs were predicted and translated into amino acid sequences. Metabolic pathway analysis and subcellular localization helped define the roles of key bacterial proteins. Two druggable proteins, WP_012000829.1 and WP_275157394.1, were discovered as promising targets. Alpha Fold provided 3D structures, and a library of 1600 echinoderm metabolites was docked against these proteins, with Ampicillin, Levofloxacin, and Doxycycline as controls. Notably, CMNPD13085 and CMNPD15632 exhibited the highest binding affinities for WP_012000829.1 and WP_275157394.1, respectively. Molecular dynamics simulations and MM-GBSA binding free energy complemented docking results. However, acknowledging the reliance on computational validations, the study emphasizes the need for essential in-vitro research to transform these potential inhibitors into therapeutic drugs.

Abstract Background Malignant ureteral obstruction (MUO) is a serious health condition in which a malignant tumor compresses the ureter. The optimal decompressive intervention in MUO remains unclear. This study was conducted to assess and compare renal function, the occurrence of ureterohydronephrosis (UHN), intraoperative, and postoperative complications among patients with MUO who underwent double J stenting (DJS) and percutaneous nephrostomy (PCN) in the Palestinian practice. Methods This study was conducted in retrospective design in one of the main tertiary care hospitals in the West Bank of Palestine. The data were collected from the electronic health information system of the hospital for the patients with MUO who received either DJS or PCN as a decompressive intervention from January 2018 to January 2024. Results In this retrospective analysis, 62 patients who had stage 2 to stage 4 cancer and suffered MUO were included. The mean age of the patients was 60.8 ± 13.6 years. Of the patients, 40 (64.5%) were male and 22 (35.5%) were female. Of the patients, 26 (41.9%) had urinary bladder cancer. Of the patients, 23 (37.1%) had flank pain and 16 (25.8%) had lower urinary tract symptoms. Of the patients, 34 (54.8%) experienced bilateral UHN and 28 (45.2%) experienced unilateral UHN. In this study, 43 patients (69.4%) received PCN, and 19 (30.6%) received DJS as a decompressive intervention. Of the patients, 36 (58.1%) suffered postoperative complications. Stent migration/slip, UTIs, and urosepsis were the most commonly reported postoperative complications. There were no statistically significant differences in the occurrence of intraoperative complications, postoperative complications, time elapsed from receiving the decompression intervention to the diagnosis of complications, ICU admission, prognosis of UHN, serum creatinine, and serum BUN between both decompressive interventions. Conclusion Despite improvements in renal functions, creatinine and BUN levels remained abnormal even after receiving a decompressive intervention. Postoperative complications were frequently reported among patients who received DJS or PCN as decompressive interventions. Larger prospective studies are still needed to determine the optimal interventions to improve outcomes, quality of life, and survival rates of patients with DJS or PCN.

Abstract Purpose Robotic surgery is increasingly utilized in the treatment of urothelial carcinoma of the upper urinary tract (UTUC). This study investigates the advantages and burden of robot-assisted surgical treatment of the urothelial carcinoma of the upper urinary tract in a referral urological department, along with their functional and oncological results. Methods The study included 66 prospectively enrolled patients who were surgically treated by a single, robotically specialized surgeon between July 2019 and December 2023. Patients were divided into three groups. Group 1: 50 patients underwent robot-assisted radical Nephroureterectomy (RANU) with bladder cuff excision, Group 2: 11 patients underwent RANU simultaneously with robot-assisted radical cystectomy (RARC), and Group 3: 5 patients underwent robot-assisted segmental ureterectomy (RASU). Clinical and oncological parameters were compared. Perioperative morbidity according to Clavien-Dindo was the primary endpoint of our study. The secondary endpoint was oncologic outcomes. Results 37.8% of patients had locally advanced carcinomas. The average console time of RANU with bladder cuff excision was 69 min. The rate of positive surgical margins was n = 1/66 (2%). Lymphadenectomy (LAD) was performed on 30% of patients, with a mean of 13.7 lymph nodes removed. Of those who received LAD, 33% had lymph node metastasis. n = 6/66 (9%) patients received blood transfusion. The overall complication rate was 24%. The readmission rate was 7.5%. With a median follow-up of 26 months, the 2-year recurrence-free survival rate was 84.4%, and the 2-year overall survival rate was 94%. Conclusion Robotic surgery is a feasible option for treating UTUC that can be adapted to meet the surgical needs of each patient. Prospective studies are warranted to confirm its benefits.

Abstract Background Burnout syndrome is marked by three primary domains: emotional exhaustion, depersonalization, and low personal accomplishment. This study assessed the prevalence of burnout syndrome among anesthesiologists, anesthesia technicians, and intensive care unit (ICU) nurses in Palestinian hospitals. In addition, this study also sought to assess associations and identify the factors that can predict higher burnout among anesthesiologists, anesthesia technicians, and ICU nurses. Methods This study was conducted in a cross-sectional design using a questionnaire between October 2023 and December 2023. The questionnaire collected the demographic variables of the healthcare providers, their living conditions, lifestyle, working conditions, job satisfaction, and intention to change the profession. The healthcare providers were included from 12 different hospitals. Burnout syndrome was assessed using the Maslach Burnout Inventory-Human Services Survey for Medical Personnel (MBI-HSS-MP). Results A total of 250 healthcare providers were invited to participate in this study, of those, 212 completed the questionnaire, giving a response rate of 84.8%. Of the healthcare providers, 72 (34.0%) were anesthesiologists, 41 (19.3%) were anesthesia technicians, and 99 (46.7%) were ICU nurses. Of all healthcare providers, 151 (71.2%) reported emotional exhaustion, 125 (59%) reported depersonalization and 145 (68.4%) reported a lack of personal achievement based on the MBI-HSS-MP criteria for burnout. Multiple linear regression showed that higher emotional exhaustion scores could be predicted by the number of working hours per day (p-value = 0.039) and higher depersonalization scores could be predicted by having children (p-value = 0.001). On the other hand, lower personal achievement scores could be predicted by having children (p-value = 0.006), not owning a car (p-value = 0.036), and having more night shifts (p-value = 0.049). Conclusions The findings of this study indicated that burnout syndrome was prevalent among anesthesiologists, anesthesia technicians, and ICU nurses in Palestinian hospitals. Healthcare authorities and professional bodies should consider designing interventions to reduce burnout and improve the psychological well-being of anesthesiologists, anesthesia technicians, and ICU nurses. Further studies are required to identify the most effective interventions for reducing burnout among anesthesiologists, anesthesia technicians, and ICU nurses in Palestine.

This paper explores the asymmetric effects of life and non-life insurance on economic growth in Saudi Arabia. Quarterly data on insurance penetration rates and GDP growth from 2009 to 2022, obtained from the Global Economy, Saudi Arabian Monetary Authority, and World Bank databases, are utilized. A nonlinear autoregressive distributed lag (NARDL) model is employed to examine the relationships between insurance and growth. The results reveal a significant and asymmetric relationship between life insurance penetration and GDP growth. Specifically, a 1% increase in life insurance penetration is associated with a 0.3% increase in GDP growth in the long run, while a 1% decrease shows no significant effect. For non-life insurance, both increases and decreases demonstrate significant but asymmetric impacts on growth. A 1% increase in non-life insurance penetration corresponds to a 0.2% increase in GDP growth, whereas a 1% decrease is linked to a 0.15% decrease in GDP growth. These findings support the ‘supply-leading’ hypothesis, suggesting that the insurance sector can play a leading role in promoting economic growth. The results provide new quantitative insights into the relationship between insurance and economic growth in Saudi Arabia, offering valuable implications for policymakers. It is suggested that the insurance industry can be leveraged to foster economic growth by promoting life insurance and managing the asymmetric impacts of non-life insurance.

Abstract Background Worldwide, breast cancer has replaced lung cancer and has become the most commonly diagnosed malignancy. Breast cancer poses a significant burden on the health and quality of life of women and can lead to substantial physical burdens and significant psychological problems, including distress, anxiety, depression, and sexuality-related issues, including negative body image. This study was conducted to assess how women diagnosed with, treated, and/or receiving treatment for breast cancer perceived their body image. Methods A cross-sectional study design was used to assess body image perceptions among Palestinian women diagnosed with breast cancer. The study was conducted in four different hospitals located in the West Bank of Palestine where women with breast cancer received their treatments or visited for follow-up care in the period between November 2023 and March 2024. An interviewer-administered questionnaire was used to collect the data. Body perception was assessed using the body image self-rating questionnaire for breast cancer (BISQ-BC). Results In this study, 376 women with breast cancer completed the interviewer-administered questionnaire (response rate = 75.2%. The mean age of the women was 44.0 ± 5.3 years. Of the women, 74.7% agreed or strongly agreed that they cared about their body image. On the other hand, 43.1% of the women were not satisfied with their body image and 58.8% did not think that their body image was attractive. Multiple linear regression showed that younger age, employment status, living in cities, marital status, educational level, presence of comorbidities, and longer time passes since diagnosis with breast cancer were associated with the different aspects of body image perception and behavior. Conclusion The findings of this study indicated that Palestinian women with breast cancer were concerned about their body image. The findings also indicated that breast cancer and its treatment posed a significant burden on the physical and psychosocial well-being of the affected women and impacted the different dimensions of their lives, including their perceptions of their body image. Patients with significant physical and body image changes might benefit from reconstructive surgeries, psychosocial support, cognitive behavioral therapy, and nutritional, and physical activity interventions.

Drawing on signaling theory, the current experimental study (N = 593) investigated the influence of top employer awards on the connections between the full spectrum of narcissistic personality features (i.e., agentic, antagonistic, neurotic, and communal) and perceived company prestige. The results of our experiment show that employer awards enhance prestige perceptions and that all narcissism facets are positively related to perceptions of prestige. However, the positive associations between narcissistic personality features and company prestige were less pronounced in the award condition than in the no-award condition. Our study contributes to the recruitment and employer branding literature by demonstrating that, while employer awards generally enhance an organization’s prestige, they may not do so for individuals with particular personality features.

BACKGROUND AND AIMS: Data on how to teach endosonographers needle-based confocal laser endomicroscopy (nCLE)-guided histologic diagnosis of pancreatic cystic lesions (PCLs) are limited. Hence, we developed and tested a structured educational program to train early-career endosonographers in nCLE-guided diagnosis of PCLs. METHODS: Twenty-one early-career nCLE-naïve endosonographers watched a teaching module outlining nCLE criteria for diagnosing PCLs. Participants then reviewed 80 high-yield nCLE videos, recorded diagnoses, and received expert feedback (phase 1). Observers were then randomized to a refresher feedback session or self-learning at 4 weeks. Eight weeks after training, participants independently assessed the same 80 nCLE videos without feedback and provided histologic predictions (phase 2). Diagnostic performance of nCLE to differentiate mucinous versus nonmucinous PCLs and to diagnose specific subtypes were analyzed using histopathology as the criterion standard. Learning curves were determined using cumulative sum analysis. RESULTS: Accuracy and diagnostic confidence for differentiating mucinous versus nonmucinous PCLs improved as endosonographers progressed through nCLE videos in phase 1 (P < .001). Similar trends were observed with the diagnosis of PCL subtypes. Most participants achieved competency interpreting nCLE, requiring a median of 38 assessments (range, 9-67). During phase 2, participants independently differentiated PCLs with high accuracy (89%), high confidence (83%), and substantial interobserver agreement (κ = .63). Accuracy for nCLE-guided PCL subtype diagnoses ranged from 82% to 96%. The learned nCLE skills did not deteriorate at 8 weeks and were not impacted by a refresher session. CONCLUSIONS: We developed a practical, effective, and durable educational intervention to train early-career endosonographers in nCLE-guided diagnosis of PCLs.

KRASG12C inhibitors, such as sotorasib and adagrasib, have revolutionized cancer treatment for patients with KRASG12C-mutant tumors. However, patients receiving these agents as monotherapy often develop drug resistance. To address this issue, we evaluated the combination of the PAK4 inhibitor KPT9274 and KRASG12C inhibitors in preclinical models of pancreatic ductal adenocarcinoma (PDAC) and non-small cell lung cancer (NSCLC). PAK4 is a hub molecule that links several major signaling pathways and is known for its tumorigenic role in mutant Ras-driven cancers. We found that cancer cells resistant to KRASG12C inhibitor were sensitive to KPT9274-induced growth inhibition. Furthermore, KPT9274 synergized with sotorasib and adagrasib to inhibit the growth of KRASG12C-mutant cancer cells and reduce their clonogenic potential. Mechanistically, this combination suppressed cell growth signaling and downregulated cell-cycle markers. In a PDAC cell line-derived xenograft (CDX) model, the combination of a suboptimal dose of KPT9274 with sotorasib significantly reduced the tumor burden (P= 0.002). Similarly, potent antitumor efficacy was observed in an NSCLC CDX model, in which KPT9274, given as maintenance therapy, prevented tumor relapse following the discontinuation of sotorasib treatment (P= 0.0001). Moreover, the combination of KPT9274 and sotorasib enhances survival. In conclusion, this is the first study to demonstrate that KRASG12C inhibitors can synergize with the PAK4 inhibitor KPT9274 and combining KRASG12C inhibitors with KPT9274 can lead to remarkably enhanced antitumor activity and survival benefits, providing a novel combination therapy for patients with cancer who do not respond or develop resistance to KRASG12C inhibitor treatment.
