Primary Adenocarcinoma in a Seminal Vesicular Cyst: A Case Report

Introduction: Primary adenocarcinoma of the seminal vesicle (SVC) is very rare. Presentation to the case: Herein, we reported a case of SVA of SV cyst arising in a 51-year-old deaf mute male patient. Laboratory parameters including serum prostate specific antigen (PSA) level were normal. Contrast-enhanced magnetic resonance imaging demonstrated large reterovesical cystic lesion with mural nodules. The patient was managed by radical prostatectomy and seminovesiculolectomy.  Microscopic examination revealed well-differentiated primary mucinous adenocarcinoma of left seminal vesicle cyst.   Conclusion: To the best of our knowledge, this was the first case of SVA of SV cyst arising in deaf mute patient

The risk of developing type 2 diabetes mellitus among the students of Hail University, Saudi Arabia

BackgroundGlobally, it is estimated that approximately 537 million adults are living with diabetes. Of them, more than 90% have type 2 diabetes (T2DM). In 2023, a previous meta-analysis showed that the prevalence of T2DM among the general adult population in Saudi Arabia was 28%. This study was conducted to assess the risk of developing T2DM among the students at Hail University, Saudi Arabia.MethodsThis cross-sectional study was conducted in 2022/2023 among a census sample of 740 students (both genders, aged 17–26 years) studying at nine colleges of Hail University, Saudi Arabia. The diabetes risk score was assessed using the Australian Type 2 Diabetes Risk Assessment Tool (AUSDRISK). Anthropometric measurements were measured and recorded using standard methods. Socio-demographic variables were also obtained with an interview-based questionnaire. Statistical analysis was performed using SPSS version 25.ResultsA total of 740 students were included in the final analysis. Of them, 274 (37.0%) were male students and 466 (63.0%) were female students. The mean age of the study participants is 19.9 ± 1.6 years. The findings showed that 61.9% of the study participants were at intermediate and high risk of diabetes (59.7 and 2.2%, respectively). The majority 85.7% of male students were at intermediate risk of diabetes, and 5.8% were at high risk of diabetes. In total, 44.4% of female students were at intermediate risk of diabetes, and none of them were at high risk of diabetes. For the following variables (age, gender, college name, area of the university, academic years, weight, height, and BMI), the differences were statistically significant between different categories of diabetes risk scores (P-values < 0.005).ConclusionMore than half of the students at the Hail University of Saudi Arabia have an intermediate and high risk of T2DM. Male students are at a higher risk compared to female students. The high risk of T2DM among university students should be seriously considered

Optimization and design of an aircraft's morphing wing-tip demonstrator for drag reduction at low speeds, Part II - Experimental validation using Infra-Red transition measurement from Wind Tunnel tests

In the present paper, an ‘in-house’ genetic algorithm was numerically and experimentally validated. The genetic algorithm was applied to an optimization problem for improving the aerodynamic performances of an aircraft wing tip through upper surface morphing. The optimization was performed for 16 flight cases expressed in terms of various combinations of speeds, angles of attack and aileron deflections. The displacements resulted from the optimization were used during the wind tunnel tests of the wing tip demonstrator for the actuators control to change the upper surface shape of the wing. The results of the optimization of the flow behavior for the airfoil morphing upper-surface problem were validated with wind tunnel experimental transition results obtained with infra-red Thermography on the wing-tip demonstrator. The validation proved that the 2D numerical optimization using the ‘in-house’ genetic algorithm was an appropriate tool in improving various aspects of a wing’s aerodynamic performances

Prediction of Wilms’ Tumor Susceptibility to Preoperative Chemotherapy Using a Novel Computer-Aided Prediction System

Wilms’ tumor, the most prevalent renal tumor in children, is known for its aggressive prognosis and recurrence. Treatment of Wilms’ tumor is multimodal, including surgery, chemotherapy, and occasionally, radiation therapy. Preoperative chemotherapy is used routinely in European studies and in select indications in North American trials. The objective of this study was to build a novel computer-aided prediction system for preoperative chemotherapy response in Wilms’ tumors. A total of 63 patients (age range: 6 months–14 years) were included in this study, after receiving their guardians’ informed consent. We incorporated contrast-enhanced computed tomography imaging to extract the texture, shape, and functionality-based features from Wilms’ tumors before chemotherapy. The proposed system consists of six steps: (i) delineate the tumors’ images across the three contrast phases; (ii) characterize the texture of the tumors using first- and second-order textural features; (iii) extract the shape features by applying a parametric spherical harmonics model, sphericity, and elongation; (iv) capture the intensity changes across the contrast phases to describe the tumors’ functionality; (v) apply features fusion based on the extracted features; and (vi) determine the final prediction as responsive or non-responsive via a tuned support vector machine classifier. The system achieved an overall accuracy of 95.24%, with 95.65% sensitivity and 94.12% specificity. Using the support vector machine along with the integrated features led to superior results compared with other classification models. This study integrates novel imaging markers with a machine learning classification model to make early predictions about how a Wilms’ tumor will respond to preoperative chemotherapy. This can lead to personalized management plans for Wilms’ tumors

Role of Microalbuminuria and Hypoalbuminemia as Outcome Predictors in Critically Ill Patients

Background. Assessment of microalbuminuria and hypoalbuminemia can be used as a good tool for the prediction of the ICU outcome in critically ill patients. Purpose. To evaluate and compare the prognostic significance of microalbuminuria (albumin creatinine ratio (ACR)) and serum albumin level done on admission and after twenty-four hours for the critically ill patients. Methodology. Sixty ICU patients were involved in a prospective cohort study (mean age was 44.4 ± 16.7 years, and 78.3% were males). Patients were divided into 2 groups according to mortality (survivors and nonsurvivors) and were subjected to laboratory measurement of the mentioned biomarkers on admission and after twenty-four hours. Results. There were 34 patients (56.67%) in group A (survivors) and 26 patients (43.33%) in group B (nonsurvivors). Albumin creatinine ratio on admission (ACR1) and albumin creatinine ratio after 24 hours (ACR2) were significantly lower in survivors than nonsurvivors (P values were <0.001 for both). Serum albumin level after 24 hours of admission was significantly higher in survivors than nonsurvivors (P value 0.02) while admission serum albumin was not significantly different between both groups (P value was 0.1). There was a positive correlation between ACR2 and ICU stay and mechanical ventilatory support with a strong positive correlation with the use of vasopressor therapy (r: 0.35, 0.58, and 0.73, respectively). P values were 0.005, <0.0001, and <0.0001, respectively. There was a positive correlation between ACR2 with APACHE II and SOFA scores (r: 0.46 and 0.43, respectively); P values were 0.001 and <0.0001, respectively. There was a moderate negative correlation between serum albumin on admission and after 24 hours and the duration of mechanical ventilation (r: −0.4 and −0.39, respectively) (P values were 0.001 and 0.002, respectively). By Cox regression analysis, two parameters were found to be an independent predictor of mortality in ICU patients which were age and using vasopressor treatment (P values = 0.01 and <0.001), while the other parameters were not independent predictors of mortality (P values were more than 0.05). Conclusions. Microalbuminuria on admission and after 24 hours of ICU admission could be a good predictor of mortality in critically ill patients. The serum albumin level after 24 hours of admission can predict poor outcomes in critically ill patients

Hormone Receptors and Age Distribution in Breast Cancer Patients at a University Hospital in Northern Egypt

Introduction Breast cancer is the most common cancer among Egyptian women. The disease is often advanced at diagnosis. Since molecular profiling is not feasible in routine practice, we sought to examine the association of age distribution with hormone receptor profile, disease stage and outcome among Egyptian women. Patients and Methods We conducted a retrospective review of breast cancer patients treated at Mansoura University Cancer Center in the Nile Delta from 2006 through 2011. Age groups were examined in relation to hormone receptors status and tumor clinicopathological criteria. Additionally, the effect of receptor status on disease relapse and disease-free survival was examined with logistic regression and Kaplan–Meier analysis. Results A total of 263 patients were included in the current analysis. About 66.9% (n = 176) of patients were hormone receptor positive, 14.1% (n = 37) were Her 2 /neu positive, and 19.0% (n = 50) were triple negative. Median age of the patients was 52 years and was equal across all receptor status types. Triple negative status correlated with increased risk of disease relapse (odds ratio = 1.8, P = 0.03) and with shortened disease-free survival (hazards ratio = 2.6, P < 0.01). Conclusion The age distribution and receptor status pattern in the Nile Delta region does not explain the aggressive behavior of the disease. The age of the patients at diagnosis is older than patients in earlier studies from Egypt emphasizing the importance of implementing mammographic screening programs

Postpartum acute kidney injury: Single center observational study

Background. Postpartum acute kidney injury is a serious obstetric complication, and its diagnostic definition is highly variable in the literature. Recent studies reported an incidence up to 40% in both developed and developing countries. PP-AKI is associated with an increased risk of chronic kidney disease, and cardiovascular disease. Methods. We conducted a single center case control study for PP-AKI cases. Forty six women were recruited in the study, and they represented two groups, PP-AKI group (n=18), and healthy control group (n=38). Clinical examinations and laboratory investigations were collected. Results. Hypertension and CKD were reported in 5(27.8%), and 3(16.7%) of the included women in PP-AKI group respectively, while none of healthy control women had HTN, or CKD. PP-AKI patients exhibited significantly lower mean values for blood hemoglobin levels (7.9±1.36 g/dl), platelets counts (157.9±92.3×103/mm3), and serum albumin levels (2.9±0.4 gm/dl) in comparison with healthy controls. Additionally, PP-AKI patients exhibited significantly higher mean value for serum creatinine levels (5.3±2.9 mg/dl), and higher median and range values for prothrombin time 1(1-2.7) in comparison with healthy controls. Preeclampsia was the main possible etiology of PP-AKI

Dietary nucleotides enhanced growth performance, carcass composition, blood biochemical, and histology features of European sea bass, Dicentrarchus labrax L

Nucleotides (NT), as a modern feed additive, are effective in many vital functions of cultured aquatic organisms. An experiment was performed to evaluate the effects of dietary nucleotides on the growth performance, carcass composition, liver enzymatic profile, liver, intestine, and spleen histology in European sea bass, Dicentrarchus labrax (initial weight 29.56 ± 0.083 g/fish). Four isonitrogenous (46 % crude protein) and isolipidic (16 % crude lipid) experimental diets were supplemented with different levels of nucleotides, representing N0, N500, N1000, and N1500 treatments, respectively. Each diet was fed to three net enclosures (experimental net cage: 1 × 1 × 1 m) with 0.5 m3 water volume, and each net enclosure contained eight fish. The fish were fed to satiation for 56 days. The results showed significant (P < 0.05) differences in growth performance and feed utilization indices in favor of N500 among all the treatments (P < 0.05). Seabass fed N0 and N1500 had the significantly lowest results. No significant (P < 0.05) differences in survival were detected. Fish fed diets supplemented with nucleotides exhibited significantly lower values of alkaline phosphatase activity (ALP), aspartate aminotransferase activity (AST), alanine aminotransferase activity (ALT), and bilirubin (BIL) compared with the control. The intestine, liver, and spleen histology showed the best development in N500 fed group fish compared with the other treatment, mainly N0 and N1500. In conclusion, the present experiment showed that 500 mg/kg of dietary nucleotides is the optimum level for the best growth performance, health condition, and digestive organs development of D. labrax
