Abstract: Background There is a paucity of data comparing 30-day morbidity and mortality of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one anastomosis gastric bypass (OAGB). This study aimed to compare the 30-day safety of SG, RYGB, and OAGB in propensity score-matched cohorts. Materials and methods This analysis utilised data collected from the GENEVA study which was a multicentre observational cohort study of bariatric and metabolic surgery (BMS) in 185 centres across 42 countries between 01/05/2022 and 31/10/2020 during the Coronavirus Disease-2019 (COVID-19) pandemic. 30-day complications were categorised according to the Clavien–Dindo classification. Patients receiving SG, RYGB, or OAGB were propensity-matched according to baseline characteristics and 30-day complications were compared between groups. Results In total, 6770 patients (SG 3983; OAGB 702; RYGB 2085) were included in this analysis. Prior to matching, RYGB was associated with highest 30-day complication rate (SG 5.8%; OAGB 7.5%; RYGB 8.0% (p = 0.006)). On multivariate regression modelling, Insulin-dependent type 2 diabetes mellitus and hypercholesterolaemia were associated with increased 30-day complications. Being a non-smoker was associated with reduced complication rates. When compared to SG as a reference category, RYGB, but not OAGB, was associated with an increased rate of 30-day complications. A total of 702 pairs of SG and OAGB were propensity score-matched. The complication rate in the SG group was 7.3% (n = 51) as compared to 7.5% (n = 53) in the OAGB group (p = 0.68). Similarly, 2085 pairs of SG and RYGB were propensity score-matched. The complication rate in the SG group was 6.1% (n = 127) as compared to 7.9% (n = 166) in the RYGB group (p = 0.09). And, 702 pairs of OAGB and RYGB were matched. The complication rate in both groups was the same at 7.5 % (n = 53; p = 0.07). Conclusions This global study found no significant difference in the 30-day morbidity and mortality of SG, RYGB, and OAGB in propensity score-matched cohorts.

Abstract: Background: Metabolic and bariatric surgery (MBS) is an effective treatment for adolescents with severe obesity. Objectives: This study examined the safety of MBS in adolescents during the coronavirus disease 2019 (COVID-19) pandemic. Methods: This was a global, multicentre and observational cohort study of MBS performed between May 01, 2020, and October 10,2020, in 68 centres from 24 countries. Data collection included in-hospital and 30-day COVID-19 and surgery-specific morbidity/mortality. Results: One hundred and seventy adolescent patients (mean age: 17.75 ± 1.30 years), mostly females (n=122, 71.8%), underwent MBS during the study period. The mean pre-operative weight and body mass index were 122.16 ± 15.92 kg and 43.7± 7.11 kg/m2, respectively. Although majority of patients had pre-operative testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (n=146; 85.9%), only 42.4% (n=72) of the patients were asked to self-isolate pre-operatively. Two patients developed symptomatic SARS-CoV-2 infection post-operatively (1.2%). The overall complication rate was 5.3% (n=9). There was no mortality in this cohort. Conclusions: MBS in adolescents with obesity is safe during the COVID-19 pandemic when performed within the context of local precautionary procedures (such as pre-operative testing). The 30-day morbidity rates were similar to those reported pre-pandemic. These data will help facilitate the safe re-introduction of MBS services for this group of patients.

Abstract: Background: There is a paucity of data comparing 30-day morbidity and mortality of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one anastomosis gastric bypass (OAGB). This study aimed to compare the 30-day safety of SG, RYGB, and OAGB in propensity score-matched cohorts. Materials and methods: This analysis utilised data collected from the GENEVA study which was a multicentre observational cohort study of bariatric and metabolic surgery (BMS) in 185 centres across 42 countries between 01/05/2022 and 31/10/2020 during the Coronavirus Disease-2019 (COVID-19) pandemic. 30-day complications were categorised according to the Clavien–Dindo classification. Patients receiving SG, RYGB, or OAGB were propensity-matched according to baseline characteristics and 30-day complications were compared between groups. Results: In total, 6770 patients (SG 3983; OAGB 702; RYGB 2085) were included in this analysis. Prior to matching, RYGB was associated with highest 30-day complication rate (SG 5.8%; OAGB 7.5%; RYGB 8.0% (p = 0.006)). On multivariate regression modelling, Insulin-dependent type 2 diabetes mellitus and hypercholesterolaemia were associated with increased 30-day complications. Being a non-smoker was associated with reduced complication rates. When compared to SG as a reference category, RYGB, but not OAGB, was associated with an increased rate of 30-day complications. A total of 702 pairs of SG and OAGB were propensity score-matched. The complication rate in the SG group was 7.3% (n = 51) as compared to 7.5% (n = 53) in the OAGB group (p = 0.68). Similarly, 2085 pairs of SG and RYGB were propensity score-matched. The complication rate in the SG group was 6.1% (n = 127) as compared to 7.9% (n = 166) in the RYGB group (p = 0.09). And, 702 pairs of OAGB and RYGB were matched. The complication rate in both groups was the same at 7.5 % (n = 53; p = 0.07). Conclusions: This global study found no significant difference in the 30-day morbidity and mortality of SG, RYGB, and OAGB in propensity score-matched cohorts. © 2021, The Author(s).

10. COMPARATIVE ANALYSIS OF SAFFLOWER (CARTHAMUS TINCTORIUS L.) GENOTYPES BASED ON SEED AND OIL CHARACTERISTICS.

Author: GHAREEB, S. A., HASAN, S. S., ALI, S. H. S., and AHMAD, N. S.
Subjects: SAFFLOWER, BASE oils, OILSEEDS, VEGETABLE oils, FREE fatty acids, GENOTYPES, FRENCH fries
Abstract: The performance of nine safflower genotypes was estimated for the physical properties of seeds, chemical, and physiochemical characteristics of seed oil. They are with different response to most physical properties, that are considered in machinery designation for handling, harvesting, and oil extraction process. Local and Ardny genotypes had the highest percentage of oleic acid, while linoleic was the highest in Rabiaa, indicating their high usability in food preparation. Al-Shamia is preferable for direct use in food preparation, containing the lowest palmate ratio. Free fatty acid was ranged from 31.59- 41.02% for G-2018 and Zaafarani genotypes, respectively. G-2018 had the lowest iodine value at 136.350 g I2/100 g, providing an oil with a high saturation value. Al-Shamia and Local genotypes had low palmitic and stearic acid (saturated fatty acids) percentages, therefore, a highly stable and healthy edible oil can be extracted from the plants. The principal component analyses attributed high variation among the genotypes. Local and Rabiaa genotypes could be involved in the improvement of oil quality in Kurdistan. Dissimilarity matrix clarified a wide distance between G-2018 and other genotypes based on the traits. Hybridization programs would be reasonable for the oil quality improvement of these genotypes. Thermal stability and frying qualities of oleic and linoleic oils could be studied in the future. [ABSTRACT FROM AUTHOR]

Subjects: medicine.medical_specialty, Face-to-face, Work (electrical), Workplace violence, Environmental protection, Intervention (counseling), Family medicine, Epidemiology, medicine, Affect (psychology), Logistic regression, Psychology, Test (assessment)
Abstract: Background: Violence against Taxi drivers in Zagazig City is becoming common However, the research of this issue never exists. Aim of work: to identify risk factors faced by taxi drivers for workplace violence and identifies current preventionmeasures. Subjects and methods: A cross-sectional approach was employed. A selfstructured questionnaire was used to collect data and different aspects of workplace violence against Taxi drivers at Zagazig between April and May 2011. 85 taxi drivers agreed to participate. Since most of the participants were illiterate or semi-illiterate, all the interviews were face to face, performed by the research team and filled in the questionnaire on their own. Pearson’s chi-square analysis was used to test the differences in exposure to physical and non-physical violence according to espondents’ characteristics and perpetrators characteristics. Logistic regression model was used to determine the most factor affect in the outcome exposure (violence) Results: Less than half of the respondents (40.1%) reported exposure to violence in the previous12 months; 30.6%physical assault and 16.5% to verbal assault. Logistic regression analysis was done; we found that working at night shift was the most independent factor which affects the outcome (violence). Respondents characteristics like young age ( represent (80.7) of physical violence and( 35.7%) from verbal violence. Perpetrator characteristic mostly male (100%) as regard physical violence, as regard verbal violence (64.2%) was male and( 35.8%) was female ,in the age group (19-35) represent (53.8%) of those who committed physical violence and (64.3%) of verbal violence.Consequences of both physical and verbal violence were considerable .Only 7% of victims who need treatment by doctor, (10%) had stab wounds, (5%) had been beaten and (2.5%) had fractures. In 30% of them made changes in work schedule, 75% restricttrip outside the city and 70% stop night shift. Conclusions: Taxi drivers are at high risk of violent incidents in zagazig city. The Interior Ministry needs to introduce policy and strategies for prevention and management of Taxi drivers’ violence, enhancement of incident reporting and follow up on reported events as well as providing adequatephysical and psychological support to victims of Taxi drivers violence Decision makers need to be aware of the causes and potential consequences of such events. There is an urgent need for intervention to protect taxi drivers’ health.

12. Efficacy and safety of early tacrolimus conversion to sirolimus after kidney transplantation: Long-term results of a prospective randomized study.

Author: El-Agroudy, A. E., Alarrayed, S. M., Al-Ghareeb, S. M., Farid, E., Alhelow, H., and Abdulla, S.
Subjects: RAPAMYCIN, TACROLIMUS, GRAFT versus host reaction, KIDNEY transplantation, LONGITUDINAL method, PATIENT safety, STATISTICAL sampling, SURVIVAL, RANDOMIZED controlled trials, TREATMENT effectiveness, DESCRIPTIVE statistics, THERAPEUTICS
Abstract: We report a prospective, open-label, randomized study to evaluate the safety and efficacy of converting patients with a stable renal function from tacrolimus (Tac)-based regimen to a sirolimus (SRL)-based regimen after kidney transplantation. Fifty-eight low-risk renal allograft recipients who receiving Tac 6 months posttransplant, were randomly assigned to continue Tac (n = 29) or convert to SRL (n = 29). We evaluated the 3-year outcomes including patient and graft survival, graft function, and safety profile. Three-year patient and graft survival in SRL and Tac groups were 93.1% versus 100% (P = 0.32), and 89.7% versus 100% (P= 0.11), respectively. However, the SRL group had a significantly better renal function, from the 2nd year posttransplant until the last follow-up. Four (13.8%) patients in the SRL group and 3 (10.3%) in the Tac group (P= 0.5) developed biopsy-proven acute rejection. Mean urinary protein excretion increased significantly after SRL conversion. Diastolic blood pressure was significantly lower at the end of the study in patients who eliminated Tac (80.4 vs. 75.6 mmHg in Tac and SRL group, respectively) (P = 0.03). Mean hemoglobin concentrations decreased after SRL conversion and remained significantly lower from 12 months to 36 months (P= 0.01). The mean serum cholesterol (540 ± 44 mg/dl) and triglycéride (177 ± 27 mg/dl) increased significantly in the SRL group, compared to Tac group (487 ± 62 mg/dl) (P = 0.03) and (141 ± 26 mg/dl) (P = 0.04). Our experience demonstrates that conversion to SRL from calcineurin inhibitors-based therapy may result in better renal function and blood pressure control in renal transplant recipients without an increased risk of acute rejection. However, these benefits have not resulted in a growing advantage in graft or patient survival. [ABSTRACT FROM AUTHOR]

23. MACHINE LEARNING MODEL FOR EDUCATION LEVELLING IN MULTICULTURAL COUNTRIES USING UAE AS A CASE STUDY

Author: Ghareeb, S, Hussain, A, Al-Jumeily OBE, D, and Khan, W
Subjects: QA75, QA76
Abstract: This research proposed and developed a computational framework for such scenarios using Machine Learning (ML) techniques to help predict the most suitable levels for students when transferring between curricula, assigning these levels automatically, and holding students' data throughout their academic journey. Students' datasets were collected from their educational records for two consecutive academic years to fulfil this goal, and then pre-processing techniques were applied to the raw dataset. The research focused on how machine learning can predict students' levels using several models including Artificial Neural Network and Random Forest, alongside assembled classifiers. Extensive simulation results indicated that the Levenberg-Marquardt Neural Network method (LEVNN) has the best average results among the other applied methods. A user-friendly platform has been designed based on a web-based student management system to bring both perspectives together in one platform for schools and parents. The research would help education providers predict students' correct levels more efficiently without regular examinations, saving time and cost for schools, students, and parents.

Symptoms include gastrointestinal dysmotility, cachexia, ptosis, external ophthalmoplegia, sensorimotor neuropathy and asymptomatic leukoencephalopathy. We describe the first case of MNGIE with meningoencephalitis that ultimately led to a familial diagnosis ending a diagnostic odyssey. We retrospectively reviewed the electronic medical records and sent whole exome sequencing for the index case and his family members. We report the variant c.877T>C p.(Cys293Arg) found in TYMP gene in all affected siblings showed typical clinical manifestations related to MNGIE. To the best of our knowledge, this is not described in the literature nor in the population databases dbSNP (Single Nucleotide Polymorphism Database) and gnomAD (Genome Aggregation Database). Additionally, it is located in a highly conserved residue and the bioinformatic analysis suggests it is most probably deleterious. Moreover, we estimated 550 number of cases of MNGIE (including 5 cases in this study) after performing an extensive search in the literature across 3 databases from 1983-2023. In addition, we identified 44 patients with MNGIE-like phenotype in genes other than TYMP . MNGIE-like phenotype affects POLG1 , RRM2B, LIG3, RRM1, MTTV1 , and MT-RNR1 genes., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Abstract: New quinazoline-sulfonylurea hybrids were prepared and examined for their in vivo anti-hyperglycemic activities in STZ-induced hyperglycemic rats using glibenclamide as a reference drug. Compounds VI-6-a, V, IV-4, VI-4-c, IV-6, VI-2-a, IV-1, and IV-2 were more potent than the reference glibenclamide. They induced significant reduction in the blood glucose levels of diabetic rats: 78.2, 73.9, 71.4, 67.3, 62, 60.7, 58.4, and 55.9%, respectively, while the reference glibenclamide had 55.4%. Compounds IV-1, VI-2-a, IV-2, V, and IV-6 showed more prolonged antidiabetic activity than glibenclamide. Moreover, molecular docking and pharmacokinetic studies were performed to examine binding modes of the prepared compounds against peroxisome proliferator-activated receptor gamma (PPARγ). The highest active compounds exhibited good binding affinity with high free energy of binding against PPARγ. In silico absorption, distribution, metabolism, elimination and toxicity (ADMET) studies were performed to investigate pharmacokinetics and safety of the synthesized compounds. They showed considerable human intestinal absorption with low toxicity profile.

Abstract: Recently, nano titanium silicon oxide (TiSiO 4 NPs) has been used in different fields and industries. Very few toxicological data exist for TiSiO 4 NPs. In the present study, the potential adverse effects of oral exposure to a single dose of TiSiO 4 NPs ≤ 50 nm (250 mg/kg b.w.) in adult male rats were investigated through the assessment of biomarkers for serum biochemical parameters, liver DNA damage, and histopathological examination and determination of Si and Ti in the exposed rat tissues. The results revealed that there were no significant changes in serum total protein, albumin, and triglycerides content, while total cholesterol level was significantly increased 7 days after exposure. TiSiO 4 NPs significantly increased superoxide dismutase (SOD), glutathione peroxidase (GPx), acetylcholine esterase (AChE), lactate dehydrogenase (LDH) activity, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) levels in the exposed rat serum, whereas alanine aminotransferase (ALT), aspartate aminotransferase (AST) activity, urea level, immunoglobulins (IgG and IgM) concentrations, progesterone, and testosterone levels were significantly decreased. The liver comet assay indices were significantly increased after 7 days post-exposure. Moreover, histopathological changes and the accumulation of Si and Ti in liver, kidney, spleen, and lung tissues of treated rats were recorded.

Abstract: Hypertension (HTN) is a common health problem and a major cardiovascular risk factor. Accurate measurement of blood pressure (BP) is mandatory for proper diagnosis and follow-up. The aim of this study was to evaluate the accuracy of mercury sphygmomanometer BP-measuring devices in public hospitals in Cairo, Egypt. Fifty public hospitals were included, and 10% of all mercury sphygmomanometer devices in each hospital were tested. Assessment included physical condition (e.g., mercury status, lid of the device, state of the rubber tubes), leakage rate, and calibration accuracy (as compared with a reference device). Devices were approved as accurate when they could successfully pass all three assessment tests. The total number of sphygmomanometer devices was 465. The overall pass rate was 1.3% (six devices). Twenty-five (5.2%) devices passed all of the physical tests, 50 (10.8%) passed the leakage test, and 50 (16.5%) passed the calibration accuracy test. There were 162 (34.8%) devices that showed a high leakage rate (>80 mmHg) and thus were not tested for calibration accuracy. In conclusion, most of the mercury sphygmomanometer devices in hospitals are neglected and not checked regularly for any errors. A plan should be made to gradually replace those failed devices with new, validated, and well-calibrated devices, preferably devices that do not contain mercury., (© 2020. The Author(s).)

Abstract: Background: There are data on the safety of cancer surgery and the efficacy of preventive strategies on the prevention of postoperative symptomatic COVID-19 in these patients. But there is little such data for any elective surgery. The main objectives of this study were to examine the safety of bariatric surgery (BS) during the coronavirus disease 2019 (COVID-19) pandemic and to determine the efficacy of perioperative COVID-19 protective strategies on postoperative symptomatic COVID-19 rates., Methods: We conducted an international cohort study to determine all-cause and COVID-19-specific 30-day morbidity and mortality of BS performed between 01/05/2020 and 31/10/2020., Results: Four hundred ninety-nine surgeons from 185 centres in 42 countries provided data on 7704 patients. Elective primary BS (n = 7084) was associated with a 30-day morbidity of 6.76% (n = 479) and a 30-day mortality of 0.14% (n = 10). Emergency BS, revisional BS, insulin-treated type 2 diabetes, and untreated obstructive sleep apnoea were associated with increased complications on multivariable analysis. Forty-three patients developed symptomatic COVID-19 postoperatively, with a higher risk in non-whites. Preoperative self-isolation, preoperative testing for SARS-CoV-2, and surgery in institutions not concurrently treating COVID-19 patients did not reduce the incidence of postoperative COVID-19. Postoperative symptomatic COVID-19 was more likely if the surgery was performed during a COVID-19 peak in that country., Conclusions: BS can be performed safely during the COVID-19 pandemic with appropriate perioperative protocols. There was no relationship between preoperative testing for COVID-19 and self-isolation with symptomatic postoperative COVID-19. The risk of postoperative COVID-19 risk was greater in non-whites or if BS was performed during a local peak., (© 2021. The Author(s).)

32. Different Analgesic Routes of Magnesium Sulfate: Intravenous versus Pectoralis II Interfascial Plane Block for Breast Cosmetic Surgeries.

Author: Abo-Zeid MA, Ghareeb S, and Abdelhalim MM
Abstract: Purpose: The purpose of the study is to evaluate the most effective analgesic route of magnesium sulfate (MgSO 4 ) either intravenous (i.v.) or pectoralis interfascial plane block., Patients and Methods: Fifty adult female patients were divided into two equal groups: i.v. MgSO 4 and Pecs II block MgSO 4 (Pecs MgSO 4 ) group. After general anesthesia, in i.v. MgSO 4 group, the local anesthetic (LA) for Pecs II block was prepared by adding 3 mL saline to 57 mL bupivacaine 0.25% divided equally for each side. A bolus i.v. solution of MgSO 4 10% 0.5 mL.kg -1 diluted in saline in a total volume of 100 mL was given over 15 minutes. Then, the solution for continuous i.v. infusion; 30 mL MgSO 4 10% and 70 mL saline was infused at the rate of 0.5 mL.kg -1 .h -1 intraoperatively. For PecsMgSO 4 group, LA formed of 3 mL MgSO 4 10% added to 57 mL bupivacaine 0.25%. Whereas, 100 mL saline was given as bolus i.v. followed by continuous infusion of 100 mL normal saline at the rate of 0.5 mL.kg -1 .h -1 ., Results: In the group received MgSO 4 -bupivacaine Pecs II block, there was a nonsignificant decrease in postoperative morphine consumption compared to i.v. administration of MgSO 4 . The two groups were comparable in the intensity of pain and sedation scores., Conclusion: The use of bupivacaine Pecs II block enhanced with addition of MgSO 4 to pectoralis interfascial plane block or intravenously in patients underwent breast cosmetic surgeries under general anesthesia was associated with comparable results of the postoperative morphine requirements, intensity of postoperative pain, and extension of the duration of postoperative analgesia. The intraoperative hemodynamic effects i.v. MgSO 4 were superior to the pectoralis interfascial plane route of administration., Competing Interests: There are no conflicts of interest., (Copyright: © 2019 Anesthesia: Essays and Researches.)

33. Non-noble, efficient catalyst of unsupported α-Cr 2 O 3 nanoparticles for low temperature CO Oxidation.

Author: Bumajdad A, Al-Ghareeb S, Madkour M, and Sagheer FA
Abstract: Herein, we report the synthesis of chromium oxide nanoparticles, α -Cr 2 O 3 NPs, followed by full characterization via XRD, SEM, XPS, and N 2 sorptiometry. The synthesized nanoparticles were tested as catalysts toward the oxidation of CO. The impact of calcination temperature on the catalytic activity was also investigated. CO conversion (%), light-off temperature, T 50 , data were determined. The results revealed that chromia obtained at low calcination temperature (400 °C) is more active than those obtained at high calcination temperatures (600° or 800 °C) and this is ascribed to the smaller particle size and higher surface area of this sample. The results revealed a superior catalytic activity of Cr 2 O 3 NPs at lower temperature as we reached a complete conversion at 200 °C which is high value in the forefront of the published results of other non-noble catalysts. The high activity of Cr 2 O 3 nanoparticles (T 50 as low as 98 °C) where found to be dependent on a careful selection of the calcination temperature. These results may provide effective and economic solutions to overcome one of the major environmental threats.

Abstract: The Gulf Cooperation Council-Dialysis Outcomes and Practice Patterns Study (GCC-DOPPS) marks the joining of the six Gulf region countries including Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates to the main DOPPS study in 2012. The current review is a descriptive reporting on results related to the management of anemia from these countries. Our data demonstrate consistent anemia management patterns across the GCC countries allowing the achievement of international treatment levels. Overall, the majority of hemodialysis patients were prescribed appropriate erythropoiesis-stimulating agents (ESAs) and supplemental iron, enabling the attainment of mean hemoglobin (Hb) level of 10.9 g/dL. Comparisons of the individual country profiles reveal individual differences in the choice and mode of ESA and iron administration. However, all countries displayed good compliance with guideline recommendations. The same challenges as elsewhere are faced in the GCC, with respect to optimizing Hb levels and judiciously using ESA and iron supplements. Some opportunities exist for focused efforts to fine tune inter-facility variability in anemia management based on continued data tracking. The latter is vital in enabling adopting new trends to further improve not only anemia management but also the wholesome care of dialysis patients.

Abstract: Coronary artery ectasia (CAE) is usually considered a variant of coronary artery atherosclerosis; however, a definite link has not yet been confirmed. As not all patients with CAE are symptomatic, the real incidence is unknown. The aim of this study was to evaluate the prevalence of CAE and its clinical and angiographic characteristics as well as its relation to coronary artery calcification and any associated vascular abnormality by using multidetector computed tomography (MDCT). We prospectively enrolled 2,600 patients (mean age 55 ± 10 years) who were scheduled for computed tomography coronary angiography (CTCA). CTCA was performed using 64-MDCT with dedicated software for calcium measurement. CAE was defined as an arterial segment with a diameter of >1.5 times the diameter of the adjacent normal segment. The presence of ≥70 % diameter stenosis of any major epicardial vessel was considered an obstructive lesion. CAE was encountered in 192 (7.4 %) patients and showed gender predominance in men (88 %). Patients with CAE were more hypertensive but less diabetic. Left anterior descending artery was the most commonly affected vessel. Only 16 % of CAE patients had no atherosclerotic lesion. Coronary artery calcium score (CACS) and prevalence of ascending aorta aneurysm were shown to be significantly higher in CAE patients compared to patients having no ectasia. A significant negative correlation was noted between CACS and Markis classification. CTCA is a feasible technique to identify and evaluate morphology of CAE. The link between CACS and CAE may favor the consideration that ectasia is an advanced form of atherosclerosis.

Abstract: Background: Implantation is a complex process that requires a delicate cooperation between the immune and reproductive system. Any interference in the fine balance could result in embryo loss and infertility. We have recently shown that Toll-like receptor 5 activation results in a decrease of trophoblast cells binding to endometrial cells in an in vitro model of human implantation. However, little is known about the downstream signalling leading to the observed failure in implantation and the factors that modulate this immune response., Methods and Principal Findings: An in vitro model of embryo implantation was used to evaluate the effect of trophoblasts and flagellin on the activation of NF-κB in endometrial cells and whether TLR5-related in vitro implantation failure is signalled through NF-κB. We generated two different NF-κB reporting cell lines by transfecting either an immortalized endometrial epithelial cell line (hTERT-EECs) or a human endometrial carcinoma cell line (Ishikawa 3-H-12) with a plasmid containing the secreted alkaline phosphatase (SEAP) under the control of five NF-κB sites. The presence of trophoblast cells as well as flagellin increased NF-κB activity when compared to controls. The NF-κB activation induced by flagellin was further increased by the addition of trophoblast cells. Moreover, blocking NF-κB signalling with a specific inhibitor (BAY11-7082) was able to restore the binding ability of our trophoblast cell line to the endometrial monolayer., Conclusions: These are the first results showing a local effect of the trophoblasts on the innate immune response of the endometrial epithelium. Moreover, we show that implantation failure caused by intrauterine infections could be associated with abnormal levels of NF-κB activation. Further studies are needed to evaluate the target genes through which NF-κB activation after TLR5 stimulation lead to failure in implantation and the effect of the embryo on those genes. Understanding these pathways could help in the diagnosis and treatment of implantation failure cases.

Abstract: We studied the characteristics and the predictors of survival in Bahraini renal transplant recipients with an allograft that functioned for more than 10 years. Seventy-eight patients underwent renal transplantation between 1982 and 1999. Among them, 56 patients maintained functioning allografts for more than 10 years (range 10-30 years). Characteristics of the surviving patients, data on graft survival, and determinants of outcome were obtained by reviewing all medical records. The mean age at time of renal transplantation was 33.6 ± 15.3 years. The source of the graft in 42 (75%) recipients was from living related donors with a mean age of 31.4 ± 7.7 years, and it was the first graft in 48 recipients. The primary immunosuppression regimen consisted of cyclosporine (CsA) and prednisolone. Azathioprine (AZA) was given to 52 (92.9%) recipients, while four patients received steroids and AZA only. Induction therapy was administered to 30 patients in the CsA group. Acute rejection episodes occurred in eight (14.3%) patients, of whom two experienced two episodes. During the last follow-up in January 2010, the mean serum creatinine was 118.3 ± 46.5 μmol/L. A history of cancer was noted in one patient, whereas hypertension was encountered in 54% and diabetes mellitus in 20.5%. We compared the graft functioning group with the graft failure group and found that the independent determinants of long-term graft survival included time of late acute rejection episodes and histopathologic findings of chronic allograft damage, post-transplant hypertension and serum creatinine at one year. We conclude that renal transplantation even in its earliest years and despite the associated numerous complications has provided a ten-year or more of near-normal life to patients with end-stage renal disease.

Abstract: Objective: Patients on peritoneal dialysis (PD) can develop uremic symptoms as their residual renal function declines. In this retrospective study, we assessed the effect of increasing the dose of dialysis in patients who developed uremic symptoms., Methods: Patients on PD who had an increase in their dialysis dose due to either the appearance of uremic symptoms or to worsening biochemical parameters were included in this study. These patients had to have been on PD for at least 6 months before and after the increase in their dialysis dose. Patients whose dialysis dose was increased after the initial Adequest (done within 2-3 months of starting PD) findings or for reasons other than underdialysis were excluded from this study. The symptoms studied in 104 patients included fatigue, anorexia, insomnia, pruritus and nausea. The presence or absence of theses symptoms was evaluated before and after the increase in the dialysis volume. Several clinical and laboratory data including the adequacy results were compared before and after the increase in dialysis dose., Results: Patients were on PD for 24.6+/-16 months when dialysis dose was increased. Eighty-five (82%) of them were on continuous ambulatory peritoneal dialysis (CAPD) while the remaining were on continuous cycler peritoneal dialysis (CCPD). Fatigue was the most common symptom that led to an increase in the dialysis dose (64%). The prevalence of all the symptoms studied decreased significantly after the increase in dose of dialysis. The weekly peritoneal creatinine clearance increased from 47.35+/-0.88 to 57.34+/-1.401 (P < 0.0001) and the weekly Kt/V increased from 1.8+/-0.03 to 2.27+/-0.05 (P < 0.0001). The daily urine volume and the residual GFR decreased from 318.7+/-36.4 to 151.9+/-22.8 ml/day (P < 0.0001) and 2.05+/-0.2 to 0.82+/-0.12 ml/min (P < 0.0001) respectively during the study period., Conclusion: The prevalence of all uremic symptoms decreased significantly after the daily dialysate volume was increased. The improvement in symptoms despite the decline in residual function emphasizes the beneficial effect of increased dialysate volume, which produced a significantly higher peritoneal creatinine clearance and Kt/V after the change in the PD prescription.

Abstract: Renal cell carcinoma is a rare but serious complication in ESRD patients. In these patients the incidence of renal cell carcinoma (RCC) is 20-40 times higher than in the general population. We performed a retrospective study to measure the incidence rate, prevalence, characteristics and survival among our peritoneal dialysis (PD) patients diagnosed with renal cell carcinoma. The study was carried out among 607 patients who were on the PD program from January 1997 to June 2002. RCC was detected in eight patients (four males and four females) with mean age of 52.1 +/- 10.6 years. Among these eight patients four were new cases that were diagnosed before the patients were started on dialysis (three in native kidneys and one in a transplanted kidney). In the other four patients the RCC was diagnosed after they had been on dialysis for 33-204 months (mean 60.75 +/- 50.48). We found an incidence rate of 1.3 per 1000 patients per year and a prevalence of 1.3%. Six of the eight patients had renal cysts. Tumor size was less than 7 cm in seven patients and in the other patient it was 8.5 cm. Seven of eight patients were alive at the time of study with a survival time ranging from 3-138 months (mean 122.25 +/- 88.2) months. In one patient, the RCC metastasised to the scalp, and, in two other patients, the tumors subsequently involved the second kidney. A cardiovascular complication was the cause of one death. Two patients received a renal transplant 36 and 66 months after diagnosis. We conclude that despite the low rate of metastases and mortality in our study, regular ultrasonography should be added to the follow-up of PD patients. Renal transplantation can be considered in these ESRD patients with RCC; however, close follow-up for metastases is recommended.

Abstract: The aim of this study was to evaluate the relations between left ventricular (LV) functional abnormalities, microangiopathy, and autonomic dysfunction in patients with non-insulin-dependent diabetes mellitus (NIDDM). We studied 66 normotensive patients with NIDDM of > or =4 years' duration (age, 51 +/- 4.5 years; 35 men) and no clinical evidence of cardiac disease. Twenty-one healthy subjects matched for age and sex served as a control group. Echocardiography and Doppler studies were performed to assess LV systolic and diastolic function. Microangiopathy was assessed by fundus examination. Autonomic function was assessed by standing blood pressure and heart rate response to Valsalva maneuver. Patients with NIDDM had a lower ejection fraction (58% +/- 11% versus 66% +/- 4%, P <.0001), E-F deceleration slope (382 +/- 75 versus 427 +/- 31 cm/s(2), P <.05), and E velocity (55 +/- 11 vs. 58 +/- 6 cm/s, P =.02) of the mitral diastolic flow, compared with control subjects, respectively. Patients with ejection fraction <50% had a higher prevalence of retinopathy (65% versus 29%, P <.005), abnormal blood pressure response to standing (53% versus 8%, P <.0005), and proteinuria (65% versus 27%, P =.006). An inverse correlation was found between the duration of diabetes and both the ejection fraction (r = -0.53, P <.05) and E/A ratio (r = -0.4, P <.005). E/A ratio <1 was associated with a higher prevalence of retinopathy (49% versus 20%, P =.01) and abnormal blood pressure response to standing (29% versus 4%, P <.005). Patients with NIDDM and no symptoms of cardiovascular disease have a reduced LV systolic and diastolic function as compared with healthy subjects. LV systolic and diastolic abnormalities are correlated with the duration of diabetes and with other diabetic microangiopathies such as diabetic retinopathy and neuropathy.
