Synthesis, characterization and evaluation of new alternative ruthenium complex for dye sensitized solar cells.

For first time, new innovative ruthenium N3-Dye anchored with selenium (Se) and N3 dye anchored with sulphur atoms were synthesized in a good yield. Dyes are applied and evaluated in performance of dye sensitized solar cell. N3-Se dye showed superior photochemical& electrochemical behavior and high rate electron transfer across anode surface than N3-S dye. The better optical and electrochemical activities would make Se-dye a candidate for applications in solar cells. Half life time of N3-S showed a single exponential decay with an average lifetime of 0.8 ns. For N3-Se dye, decay curve was fitted by sum two exponential functions with 75% and 25% counts have 2.5 ns and 30 ns respectively. Solar cells were fabricated and analyzed to determine their solar-to-electric conversion efficiency under standard AM 1.5 sunlight. Commercial N3 dyes showed current density (Jsc) of 17.813 mA cm-2, open circuit potential (Voc) of 0.678 V, filling factor (FF) of 0.607 and conversion efficiencies (η) of 7.3%. Corresponding values for N3-S dye, Jsc 11.2 mA cm-2, Voc 0.650 V, FF 0.681 and η 5%. Se-N3 dye, showed Jsc = 6.670 mA cm-2, Voc = 0.6004 V, FF = 0.77 and η = 3.09%. Long lifetime of N3-Se caused low practical performance.

A Rare Case of Gas Forming Enterobacter cloacae Leading to Bleeding Mycotic Pseudoaneurysm of Transplant Renal Artery Culminating in Graft Nephrectomy.

Enterobacter cloacae belongs to Enterobacter genus. It is a common gram-negative, facultative anaerobic, rod-shaped organism. It causes a variety of nosocomial infections including urinary tract infection, pneumonia, wound infection, osteomyelitis and endocarditis. Over time Enterobacter cloacae complex (ECC) has developed to be resistant to antibiotics including carbapenem. It has been rarely reported to cause gas gangrene and never been reported to cause pseudoaneurysm (PA) of transplant renal artery. We report and share our experience with this rare case of gas forming and muti-drug resistant ECC which led to mycotic PA of transplant renal artery, complicated by bleeding and infected hematoma and which resulted in graft nephrectomy.

Prognostic impact of chronic lymphocytic leukemia comorbidity index in a young population: a real-world evidence study of a national gulf region cohort.

In chronic lymphocytic leukaemia (CLL), comorbidities assessed by the CLL comorbidity index (CLL-CI) have been associated with outcomes in Western cohorts. We conducted a retrospective analysis of an unselected Middle Eastern cohort of newly diagnosed CLL patients seen at the Kuwait Cancer Control Center (n = 300). Compared to Western studies, these Middle Eastern patients were diagnosed at a younger age (median of 59) and had a higher comorbidity burden (69% non-low risk CLL-CI). A higher CLL-CI score was independently associated with significantly shorter event-free survival and greater risk of death. Our analysis demonstrates that CLL-CI is a valuable tool for comorbidity assessment and prognostic influence in (relatively young) Middle Eastern CLL patients.

Short-term data suggests cognitive benefits in the elderly with single-implant overdentures.

DESIGN: This study was an extension of a randomized crossover clinical trial approved by the institutional ethics committee (approval number: D2014-148) and adhered to the CONSORT guidelines. The original study juxtaposed patient contentment with single-implant overdentures (1-IODs) against conventional complete dentures (CCDs), with patient satisfaction being the primary focus. In this follow-up study, the cognitive function of edentulous patients receiving 1-IODs was assessed, specifically monitoring for the emergence of mild cognitive impairment (MCI) throughout a three-year period. Patient outcomes were systematically recorded at predetermined intervals: initially, two months post-1-IOD placement, after one year (with groups alternated between denture types at eight-month marks), then after two and three years. A prosthodontist with a decade of expertise performed all denture-related procedures. This follow-up emphasized the cognitive outcomes using the Montreal Cognitive Assessment (MoCA-J), considering it alongside previously documented results on masticatory function, bone resorption, survival rates, and patient-reported outcomes. CASE SELECTION: Between 2015 and 2016, a follow-up study enrolled edentulous patients over 50 years of age who were proficient in Japanese, had sufficient mandibular bone for implants, and were free of systemic health issues and habits that could impact oral health. The participants were randomly divided into two groups after receiving a central mandibular implant. Group 1 initially used 1-IODs, and Group 2 used unloaded CCDs. After two months and subsequent periods, they swapped denture types. Eventually, all patients chose 1-IODs for continued use. Implant success was monitored over three years. The design featured block randomization and accounted for a sample size of 22, determined to be sufficient for evaluating the primary outcome of patient satisfaction. All patients underwent careful allocation and received customized dental interventions, with detailed radiographic planning and surgical precision guiding the implantation process. DATA ANALYSIS: Multivariable linear mixed models were used to assess within-group changes in both overall and specific cognitive function scores across five timepoints. Age, assessment interval, and upper jaw denture status were incorporated as consistent variables, while individual participants were considered variable elements in the analysis. SPSS software version 22.0 was utilized to conduct the statistical tests, and a p value threshold of 0.05 was predetermined to establish statistical significance. RESULTS: Twenty-two patients with edentulous mandibles received 1-IODs. Memory and executive functions saw significant score increases at multiple timepoints over the three-year period, with statistical significance. Though one participant dropped out and another passed away, and two did not complete the 3-year follow-up, the remaining 18 participants provided comprehensive data. Age and type of maxillary denture were significant factors, influencing MoCA-J scores with older participants and those with fixed dentures showing lower scores in certain domains. Overall, the findings illustrated the positive correlation between 1-IODs and cognitive function in older adults. CONCLUSIONS: Older adults with no natural teeth left in their mandible showed improved cognitive function after one and three years of using 1-IODs, as reflected by their total and specific cognitive domain scores. The study suggests that such implant therapy may offer protective benefits against cognitive decline, demonstrating clinical relevance for patient care, regardless of the maxillary arch (antagonist) condition.

Pros and cons of live kidney donation in prediabetics: A critical review and way forward.

There is shortage of organs, including kidneys, worldwide. Along with deceased kidney transplantation, there is a significant rise in live kidney donation. The prevalence of prediabetes (PD), including impaired fasting glucose and impaired glucose tolerance, is on the rise across the globe. Transplant teams frequently come across prediabetic kidney donors for evaluation. Prediabetics are at risk of diabetes, chronic kidney disease, cardiovascular events, stroke, neuropathy, retinopathy, dementia, depression and nonalcoholic liver disease along with increased risk of all-cause mortality. Unfortunately, most of the studies done in prediabetic kidney donors are retrospective in nature and have a short follow up period. There is lack of prospective long-term studies to know about the real risk of complications after donation. Furthermore, there are variations in recommendations from various guidelines across the globe for donations in prediabetics, leading to more confusion among clinicians. This increases the responsibility of transplant teams to take appropriate decisions in the best interest of both donors and recipients. This review focuses on pathophysiological changes of PD in kidneys, potential complications of PD, other risk factors for development of type 2 diabetes, a review of guidelines for kidney donation, the potential role of diabetes risk score and calculator in kidney donors and the way forward for the evaluation and selection of prediabetic kidney donors.

Predicting Stage Progression in Binet Stage a Chronic Lymphocytic Leukemia.

INTRODUCTION: The variable clinical course of chronic lymphocytic leukemia (CLL) and the lack of consensus on follow-up and treatment strategies have necessitated a prognostic model for identifying high-risk patients at the time of diagnosis. METHODS: We involved a retrospective analysis of demographic and clinical characteristics of 212 patients diagnosed with Binet stage A CLL and thus eligible for risk stratification by both the International Prognostic Score for Early-stage CLL (IPS-E) and the alternative IPS-E (AIPS-E). We evaluated the applicability of these prognostic indices in our young, Middle Eastern cohort (median age 59 at diagnosis). RESULTS: During the study period with a median follow-up of 3.5 years, 67 patients (32 %) experienced progression to first treatment and cumulative incidence of treatment was 13 % at 1 year and 28 % at 3 years after diagnosis. Sixty-nine (51 % of the 136 with a known value) patients harbored an unmutated immunoglobulin heavy chain gene (IGHV) and 21 (10 %) an 11q or 17p deletion with 11 % lacking FISH results. For each early-stage CLL prognostic index, more patients were identified as high-risk for disease progression (51 % of 124 patients evaluable for IPS-E; 42 % of 109 patients evaluable for AIPS-E) than intermediate-risk and low-risk. Multivariable models involving the IPS-E and AIPS-E components revealed that unmutated IGHV and elevated absolute lymphocyte count were significant predictors of earlier treatment requirement. Both prognostic scores were discriminative of time to first treatment (log-rank p < 0.001; c-statistics of 0.74 for IPS-E and 0.69 for AIPS-E). CONCLUSION: Although clarity on clinical behavior with regard to initiation of treatment remains elusive, IPS-E and AIPS-E are valuable tools for identifying high-risk patients.

Unsupervised local center of mass based scoliosis spinal segmentation and Cobb angle measurement.

Scoliosis is a medical condition in which a person's spine has an abnormal curvature and Cobb angle is a measurement used to evaluate the severity of a spinal curvature. Presently, automatic Existing Cobb angle measurement techniques require huge dataset, time-consuming, and needs significant effort. So, it is important to develop an unsupervised method for the measurement of Cobb angle with good accuracy. In this work, an unsupervised local center of mass (LCM) technique is proposed to segment the spine region and further novel Cobb angle measurement method is proposed for accurate measurement. Validation of the proposed method was carried out on 2D X-ray images from the Saudi Arabian population. Segmentation results were compared with GMM-Based Hidden Markov Random Field (GMM-HMRF) segmentation method based on sensitivity, specificity, and dice score. Based on the findings, it can be observed that our proposed segmentation method provides an overall accuracy of 97.3% whereas GMM-HMRF has an accuracy of 89.19%. Also, the proposed method has a higher dice score of 0.54 compared to GMM-HMRF. To further evaluate the effectiveness of the approach in the Cobb angle measurement, the results were compared with Senior Scoliosis Surgeon at Multispecialty Hospital in Saudi Arabia. The findings indicated that the segmentation of the scoliotic spine was nearly flawless, and the Cobb angle measurements obtained through manual examination by the expert and the algorithm were nearly identical, with a discrepancy of only ± 3 degrees. Our proposed method can pave the way for accurate spinal segmentation and Cobb angle measurement among scoliosis patients by reducing observers' variability.

Effects of pharmacogenetics on pharmacokinetics and toxicity of doxorubicin in Egyptian breast cancer patients.

This study investigates the impact of single nucleotide polymorphisms in genes (SLC22A16 and CBR1) involved in the pharmacokinetics and toxicity of doxorubicin (DOX) in Egyptian female patients with breast cancer.Patients administered DOX (60 mg/m2) for 4 cycles every 3 weeks. The peak DOX plasma concentration was measured using a validated chromatographic method. The genotyping for the selected SNPs, SLC22A16 T > C (rs714368), and CBR1 C > T (rs20572), was performed by RT-PCR. Patients were monitored for hematological and cardiac toxicities.The variant carriers of CBR1 C > T (rs20572) exhibited significantly higher DOX concentration, but no significant association to DOX-induced hematological toxicity. On the other hand, SLC22A16 T > C (rs714368) had no significant influence on DOX plasma concentration, but was significantly correlated with lower risk of neutropenia (OR 0.31, 95% CI 0.12-0.75, p = 0.01) and leukopoenia (OR 0.18, 95% CI 0.07-0.5, p = 0.001). DOX-related cardiotoxicity was correlated with the cumulative dose of DOX (R = 0.238, p = 0.017), but not with any of the two examined SNPs.Genetic polymorphisms in SLC22A16 and CBR1 may explain the inter-individual variations in DOX pharmacokinetics and toxicity. Using pharmacogenetic testing is important to customise drug therapy for cancer patients treated with anthracyclines.

Treatment of elderly patients with non-ST-elevation myocardial infarction: the nationwide POPular age registry.

OBJECTIVE: We describe the current treatment of elderly patients with non-ST-elevation myocardial infarction (NSTEMI) enrolled in a national registry. METHODS: The POPular AGE registry is a prospective, multicentre study of patients ≥ 75 years of age presenting with NSTEMI, performed in the Netherlands. Management was at the discretion of the treating physician. Cardiovascular events consisted of cardiovascular death, myocardial infarction and ischaemic stroke. Bleeding was classified according to the Bleeding Academic Research Consortium (BARC) criteria. RESULTS: A total of 646 patients were enrolled between August 2016 and May 2018. Median age was 81 (IQR 77-84) years and 58% were male. Overall, 75% underwent coronary angiography, 40% percutaneous coronary intervention, and 11% coronary artery bypass grafting, while 49.8% received pharmacological therapy only. At discharge, dual antiplatelet therapy (aspirin and P2Y12 inhibitor) was prescribed to 56.7%, and 27.4% received oral anticoagulation plus at least one antiplatelet agent. At 1­year follow-up, cardiovascular death, myocardial infarction or stroke had occurred in 13.6% and major bleeding (BARC 3 and 5) in 3.9% of patients. The risk of both cardiovascular events and major bleeding was highest during the 1st month. However, cardiovascular risk was three times as high as bleeding risk in this elderly population, both after 1 month and after 1 year. CONCLUSIONS: In this national registry of elderly patients with NSTEMI, the majority are treated according to current European Society of Cardiology guidelines. Both the cardiovascular and bleeding risk are highest during the 1st month after NSTEMI. However, the cardiovascular risk was three times as high as the bleeding risk.

Antiurolithiasis activities of Zea mays extract and its mechanism as antiurolithiasis remedy.

This study aimed to demonstrate the role of Zea mays or corn silk (CS) in the treatment of kidney stones after its proven effectiveness in folk medicine. Twenty-four rats were divided into four groups, the first represented the control group (negative control), and the second (positive control), was treated with 75% of ethylene glycol (EG) and 1% of ammonium chloride (AC) to induce stones in the kidneys of experimental animals. The animals of the third and fourth groups were treated with the same proportions of EG and AC, with the addition of extract of CS at a ratio of 200 and 400 mg/kg. After the 28th day, the blood samples were taken from rats. All kidneys of rats from all groups were taken to histological examination. Another ten rats were divided into two groups and took the same time as the original experiment. Group E took a normal diet and served as negative control group whereas the group F took a normal diet with 500 mg/kg of CS to investigate the mechanism of CS as antiurolithiatic treatment. Blood samples were collected on the last day of the experiment to perform the required analyses. The rats were dissected and liver and kidney samples were taken to complete the histological study. The results showed a significant decrease in the CS group in plasma MDA, serum urea, and creatinine. Moreover, the histological study, in the CS rats group appeared to be fewer CaOx crystals. On the other hand, we observed a significant increase in urinary pH, urine volume urinary Mg, and citrate in-group E when compared with the F group. In conclusion, we infer that CS works as an antiurolithiatic drug by increasing urinary pH, diuresis, and its nephroprotective vims. So, we advise its use as an antiurolithiasis treatment but in its pharmaceutical forms.

Telogen effluvium and COVID-19: a cross-sectional study.

OBJECTIVE: COVID-19 is a febrile infectious disease caused by severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). This virus affects several organs, including the skin. Acute telogen effluvium (TE) is a non-scarring hair loss characterized by diffuse hair shedding that begins three months after a stressful event and can last up to six months. COVID-19 infection is one of these potential stressors. Recently, there has been a reported link between increased scalp hair shedding and post-infection patients during the COVID-19 outbreak. The present work aimed to study the possible effects of COVID-19 on hair and the relationship between COVID-19 and TE and to assess the level of awareness about TE in the Asir region of Saudi Arabia. SUBJECTS AND METHODS: A questionnaire-based cross-sectional study was conducted using a pre-validated questionnaire. The study involved 561 participants from the Asir region of Saudi Arabia. Eligible participants were individuals from the Asir region who were 20 years of age or older, had previously contracted COVID-19 and had no history of TE before infection. All statistical methods used were two-tailed with an alpha level of 0.05, considering significance if the p-value was lower than or equal to 0.05. RESULTS: A total of 1,000 eligible participants completed the study questionnaire. The mean age was 32.5 ± 13.9 years, and 494 (88.1%) participants were females. In addition, 558 (99.5%) of the study participants had received the COVID-19 vaccine. A total of 411 (73.3%) participants experienced an increase in hair loss after COVID-19 infection, and 171 (30.5%) began suffering from pain when combing their hair. In addition, 182 participants (32.4%) had a family history of TE. Only 109 (10.9%) participants had a good awareness level about TE, while 452 (80.6%) had an overall poor awareness level. There was a significant relationship between the level of awareness and age, where 23.9% of the participants aged 20-29 years had a good level of awareness vs. 16.1% of others aged 40 years or older (p = 0.041). Moreover, 26.9% of participants with a family history of TE had a good awareness of TE, vs. 15.8% of those with no family history of TE (p = 0.002). In addition, significant correlations were found between increased hair loss post-COVID-19 infection and female gender (77.3% vs. 43.3%; p = 0.001) as well as suffering from pain when combing hair (86.5% vs. 65.5%; p = 0.001). CONCLUSIONS: In our study, the incidence of TE was highly related to COVID-19 infections among both sexes. However, the incidence was greater among the female population. The awareness level toward post-COVID-19 TE was poor among most of the participants in our study.

Evidence-based Management of Chronic Lymphocytic Leukemia: Consensus Statements from the Gulf Region.

INTRODUCTION: Despite recent advances in diagnosis, prognostication, and treatment options, chronic lymphocytic leukemia (CLL) is still a largely incurable disease. New concepts on diagnosis, staging, treatment, and follow-up on CLL have been incorporated throughout recent years. The lack of regional consensus guidelines has led to varying practices in the management of patients with CLL in the region. AIM: This manuscript aims to reach a consensus among expert hematologists regarding the definitions, classifications, and related practices of CLL. The experts developed a set of statements utilizing their personal experience together with the current literature on CLL management. This consensus aims to provide guidance for healthcare professionals involved in the management of CLL and serves as a step in developing regional guidelines. METHODS: Eight experts responded to 50 statements regarding the diagnosis, staging, treatment, and prognosis of CLL with three potential answering alternatives ranging between agree, disagree, and abstain. This consensus adopted a modified Delphi consensus methodology. A consensus was reached when at least 75% of the agreement to the answer were reached. This manuscript presents the scientific insights of the participating attendees, panel discussions, and the supporting literature review. RESULTS: Of the 50 statements, a consensus was reached on almost all statements. Statements covered CLL-related topics, including diagnostic evaluation, staging, risk assessment, different patient profiles, prognostic evaluation, treatment decision, therapy sequences, response evaluation, complications, and CLL during the COVID-19 pandemic. DISCUSSION/CONCLUSION: In recent years, CLL management has progressed significantly with many diagnostic tests and several novel treatments becoming available. This consensus gathers decades of consolidated principles, novel research, and promising prospects for the management of this disease.

Adding empagliflozin to sitagliptin plus metformin vs. adding sitagliptin to empagliflozin plus metformin as triple therapy in Egyptian patients with type 2 diabetes: a 12-week open trial.

OBJECTIVE: This study aimed to compare 12.5 mg empagliflozin effectiveness and safety vs. 50 mg sitagliptin twice daily as an add-on triple medication in Egyptians with type 2 diabetes. PATIENTS AND METHODS: Patients with hemoglobin A1c (HbA1c) between 53 and 86 mmol/mol after receiving open-label either sitagliptin 50 mg (n = 85) or empagliflozin 12.5 mg (n = 85) twice daily for 12 weeks were afterward taken into account for the administration of open-label empagliflozin 12.5 mg (n = 40) and sitagliptin 50 mg (n = 28) respectively twice daily for another 12 weeks of treatment as an added-on triple therapy. Both groups of patients kept taking metformin and empagliflozin 12.5 mg or sitagliptin 50 mg twice daily as prescribed. The HbA1c change from baseline after 12 weeks of triple-added-on therapy was the main endpoint. RESULTS: The sitagliptin group receiving empagliflozin saw a substantial drop in HbA1c, fasting and postprandial plasma glucose levels, body weight, and blood pressure compared to the starting point. As opposed to that, adding sitagliptin to the empagliflozin group non-significantly reduced HbA1c, fasting, and postprandial plasma glucose levels, and systolic blood pressure from baseline but significantly reduced body weight and diastolic blood pressure. Comparing the two groups, adding empagliflozin significantly reduced HbA1c, fasting, and postprandial plasma glucose levels (p < 0.001 for all except fasting plasma glucose level, p = 0.002). While the patient's weight and blood pressure were not significantly affected. CONCLUSIONS: Empagliflozin was superior to sitagliptin in relation to glycemic control, weight, and systolic/diastolic blood pressure reduction.

Evaluation of the CLL-IPI and IPS-E Prognostic Indices in a Young Middle Eastern Population with Chronic Lymphocytic Leukemia: A Retrospective Analysis at the Kuwait Cancer Control Center.

INTRODUCTION: The Chronic Lymphocytic Leukemia International Prognostic Index (CLL-IPI) is a powerful prognostic tool validated in multiple Western populations. However, its utility in the young Middle Eastern population is unknown. METHODOLOGY: We conducted a retrospective analysis of 152 unselected patients with chronic lymphocytic leukemia (CLL) diagnosed between 2008 and 2022 at the Kuwait Cancer Control Center, which serves as the sole cancer center in Kuwait. The evaluation of the CLL-IPI was based on the assessment of event-free survival (EFS) across the entire cohort. Subsequently, we compared the CLL-IPI with the International Prognostic Score for Early-stage patients (IPS-E) in order to predict the time to first treatment specifically within the subgroup of patients diagnosed with early-stage disease. RESULTS: The median age of the study cohort was 59.9 years (IQR, 53.1-68.8). The 5-year EFS rates for the low, intermediate, and high/very high-risk categories were approximately 82%, 34%, and 23%, respectively, p < 0.001 (C-statistic = 0.67). On multivariate analysis, advanced stage and unmated IGHV status were independent prognostic factors of EFS. In those with early-stage disease, cumulative 5-year treatment incidence rates for the low, intermediate, and high/very high-risk categories based on the CLL-IPI score were approximately 8%, 55%, and 55%, respectively, p = 0.001 (C-statistic = 0.70). However, based on the IPS-E score, the cumulative 5-year treatment incidence rates for the low, intermediate, and high-risk categories were approximately 0%, 10%, and 60%, respectively, p < 0.001 (C-statistic = 0.73). CONCLUSIONS: The CLL-IPI and the IPS-E are valid stratification tool in our young Middle Eastern population.

The efficacy of metformin as adjuvant to chemotherapy on IGF levels in non-diabetic female patients with progressive and non-progressive metastatic breast cancer.

OBJECTIVE: Some studies have shown that metformin inhibits the proliferation of breast cancer (BC) cells via multiple ways. One of these mechanisms is through the indirect control of the IGF-route mediated via the activation of the AMPK-LKB1 pathway in the liver, which leads to a decrease in blood glucose and insulin levels. The objective of this study was to investigate the effects of metformin as adjuvant to chemotherapy on IGF levels in female patients with progressive and non-progressive metastatic BC. PATIENTS AND METHODS: In this trial, 107 women receiving chemotherapy for metastatic breast cancer (MBC) were divided into two groups: the metformin group received 500 mg of metformin twice daily, whereas the control group did not receive any metformin. All patients received chemotherapy according to the South Egypt Cancer Institute's (SECI) established regimen. The level of IGF-1 was determined in the blood at the initiation of therapy (baseline) and at six months post treatment. RESULTS: No substantial differences were noted regarding IGF-1 levels in both groups at baseline (IGF-1 average level was 40.74 ± 36.16 vs. 32.06 ± 20.00 in the metformin and the placebo group, respectively, p = 0.462). While after six months, the mean IGF-1 level was 37.62 ± 31.35 vs. 39.12 ± 2 5.93 in the metformin and placebo groups, respectively, (p = 0.170). CONCLUSIONS: Metformin as an adjuvant to chemotherapy in MBC patients had no significant effect on reducing IGF-l levels which promotes the inhibition of the proliferation of BC cells in MBC patients.

Serially measured high-sensitivity cardiac troponin T, N-terminal-pro-B-type natriuretic peptide, high-sensitivity C-reactive protein, and growth differentiation factor 15 for risk assessment after acute coronary syndrome: the BIOMArCS cohort.

AIMS: Evidence regarding the role of serial measurements of biomarkers for risk assessment in post-acute coronary syndrome (ACS) patients is limited. The aim was to explore the prognostic value of four, serially measured biomarkers in a large, real-world cohort of post-ACS patients. METHODS AND RESULTS: BIOMArCS is a prospective, multi-centre, observational study in 844 post-ACS patients in whom 12 218 blood samples (median 17 per patient) were obtained during 1-year follow-up. The longitudinal patterns of high-sensitivity cardiac troponin T (hs-cTnT), N-terminal-pro-B-type natriuretic peptide (NT-proBNP), high-sensitivity C-reactive protein (hs-CRP), and growth differentiation factor 15 (GDF-15) were analysed in relation to the primary endpoint (PE) of cardiovascular mortality and recurrent ACS using multivariable joint models. Median age was 63 years, 78% were men and the PE was reached by 45 patients. The average biomarker levels were systematically higher in PE compared with PE-free patients. After adjustment for 6-month post-discharge Global Registry of Acute Coronary Events score, 1 standard deviation increase in log[hs-cTnT] was associated with a 61% increased risk of the PE [hazard ratio (HR) 1.61, 95% confidence interval (CI) 1.02-2.44, P = 0.045], while for log[GDF-15] this was 81% (HR 1.81, 95% CI 1.28-2.70, P = 0.001). These associations remained significant after multivariable adjustment, while NT-proBNP and hs-CRP were not. Furthermore, GDF-15 level showed an increasing trend prior to the PE (Structured Graphical Abstract). CONCLUSION: Longitudinally measured hs-cTnT and GDF-15 concentrations provide prognostic value in the risk assessment of clinically stabilized patients post-ACS.

Impact of core stability exercises vs. interferential therapy on pelvic floor muscle strength in women with pelvic organ prolapse.

OBJECTIVE: Pelvic organ prolapse (POP) is the descent of the pelvic organs into or through the vaginal walls. Females who have prolapse have symptoms that interfere with their daily lives, sexual function, and exercise. POP can have a negative effect on one's sexuality and body image. This study attempted to assess the significance of core stability exercises vs. interferential therapy on the power of the pelvic floor muscles in females with prolapsed pelvic organs. PATIENTS AND METHODS: A randomized control trial was conducted on forty participants (aged between 40-60 years, diagnosed with mild degree pelvic organ prolapse participated in the research. Participants were randomly divided into two groups: (group A; n = 20) and (group B; n = 20). The participants were tested twice, before and after 12 weeks, during which group (A) performed core stability exercises while group (B) received interferential therapy. A modified Oxford grading scale and the perineometer were used to assess how the vaginal squeeze pressure changed. RESULTS: The study's findings demonstrated that the modified Oxford grading scale values and vaginal squeeze pressure had a non-statistically significant difference (p-value ≥ 0.05) between both groups pre-treatment while had a statistically significant difference (p-value ≤ 0.05) between both groups post-treatment in favor of group A. CONCLUSIONS: It was concluded that both training programs are efficient at strengthening the pelvic floor muscles, but the core stability exercises were more effective.

Signature of real-time PCR in detection of Trichomonas vaginalis infection and its association with human papillomavirus genotype 16.

OBJECTIVE: Infection with Trichomonas vaginalis (TV) is the most prevalent non-viral sexually transmitted infection in the world. The objective of the study was to investigate the incidence of TV infection and its association with Human Papillomavirus (HPV) in a sample of Egyptian females. PATIENTS AND METHODS: 96 Egyptian females suspected for trichomoniasis were involved in our study. Vaginal washouts and cervical (cytobrush) samples were obtained from all patients and examined for T. vaginalis by direct wet mount, modified Diamond's culture medium, and real-time PCR. Cervical (cytobrush) samples were examined for HPV using real-time PCR. RESULTS: Out of 96 patients, 28 (29%) was positive for T. vaginalis by real-time PCR. HPV was detected in 33 patients (34.4%); 31 cases (32.3%) were infected with HPV of genotype 16, whereas only two cases (2.1%) had genotype 18 infection. A significant association was found between TV and HPV infection [Odds ratio (OR)=10.58; 95% confidence interval (CI): 3.819 - 29.29; p<0.001]. CONCLUSIONS: When it comes to diagnosing trichomoniasis in a susceptible population, real-time PCR is more reliable than traditional standard approaches. A significant association between TV and HPV infection was found. Further research into the processes by which these two organisms interact at the cellular level could be revealed.

Molecular screening of gastric Helicobacter pullorum recovered from different avian species in Egypt.

Helicobacter pullorum (H. pullorum) is a bacterium that colonizes the intestines of poultry and causes gastroenteritis. Because these species are known as human and/or animal pathogens, identification of H. pullorum is becoming increasingly necessary. The bacterium has been linked to colitis and hepatitis in humans after being transmitted by infected meat consumption. Misdiagnosis of other enteric zoonotic pathogens such as Campylobacter and other Helicobacter species makes the diagnosis of H. pullorum extremely difficult. This study focused on the molecular detection of H. pullorum from the stomach (proventriculus and gizzard) of different avian species as new target organs for detection and transmission between avian species. Proventriculus and gizzards were obtained from 40 freshly dead chickens and resident wild birds (n=40). Diarrhea was found in the farms that were surveyed. DNA was extracted from all collected samples to conduct PCR amplification. The samples were screened for Helicobacter genus-specific 16s using C97 and C05 primers. To confirm the existence of H. pullorum, the positive samples were sequenced. H. pullorum was recorded in two out of 40 chicken samples. In addition, H. pullorum was recorded in one out of 40 resident wild birds. The 16S rRNA gene sequence for Helicobacter genus-specific in poultry and wild birds showed a 100% homology. In conclusion, broiler chickens and resident wild birds are possible reservoirs for H. pullorum, according to this report, and possibly act as a source of infection for humans via the food supply.
