This study was conducted to evaluate the effect of dietary supplementation with Spirulina platensis (SP) on the productive performance, carcass characteristics, behavior, blood serum metabolites, hematological indices, and economic efficiency of Fayoumi broiler chickens for a 56-day. In total, 120 one-day-old broiler chicks were randomly distributed among four dietary treatments with three replicates (n = 10/group) for 8 weeks. The dietary treatments were a control basal diet without SP and the same basal diets supplemented with 0.25, 0.5, or 1.0% SP. Birds fed 1% Spirulina-supplemented diets recorded significantly (p < 0.05) higher body weight, weight gain, and feed conversion ratio and less overall feed intake and feeding behavior than those in the control group. No significant changes (p > 0.05) were recorded in the dressing percentage or the relative weights of internal organs among the different experimental groups, except for the thymus. Diets containing 0.5 or 1.0% SP saw an increase (p < 0.05) in serum total protein and globulin and a reduction (p < 0.05) in serum cholesterol concentration. The lymphocyte percentage in birds fed SP diets was significantly (p < 0.05) higher than in birds fed the control diet. These results suggest that adding SP up to 1% to the broiler diets could positively affect some important blood biochemical parameters, enhance their immunity response, and improve their growth performance. However, from an economic point of view, supplementation with 0.25% of SP is recommended for Fayoumi broiler chickens.

In this study, the authors of the current work describe a novel exponentiated Weibull distribution that they have invented. The study was written by the writers of the current work. It is required to analyze those properties once the pertinent mathematical properties have been derived. In addition to the dispersion index, the anticipated value, variance, skewness, and kurtosis are also statistically examined. The dispersion index is likewise examined. Other beneficial shapes that the new density can assume include \"bathtub,\" \"right skewed,\" \"bimodal and left skewed,\" \"unimodal and left skewed,\" and \"bimodal and right skewed.\" Additionally, these forms can be merged to create a \"bathtub.\" The term \"bathtub (U-HRF),\" \"constant,\" \"monotonically increasing,\" \"upside down-increasing (reversed U-increasing),\" \"J-HRF,\" \"upside down-constant,\" \"increasing-constant,\" or \"upside down (reversed U)\" may be used to describe the new rate of failure. The greatest likelihood method's efficiency is assessed via graphical analysis. The main measures for this procedure’s evaluation are biases and mean squared errors. The reader is given a scenario that graphically displays the adaptability and value of the innovative distribution through the use of three separate sets of actual data.

Depending on Yousof et al. (2017a), a new one parameter G family of distributions called the reciprocal Burr X-G family is defined and studied. Special member based on the well-known Burr type XII model called the reciprocal Burr X-Burr XII distribution is studied and analyzed. Relevant properties of the new family including ordinary moments, moment of the residual life, moment of the reversed residual life and incomplete moments are derived and some of them are numerically analyzed. Four different applications to real-life data sets are presented to illustrate the applicability and importance of the new family. The new family has proven to be highly capable and flexible in practical applications and statistical modeling of real data.

Blunt traumatic aortic injury (BTAI) is severe, often fatal in younger populations due to high‐energy deceleration mechanisms. Thoracic endovascular aortic repair (TEVAR) has revolutionised BTAI treatment, surpassing the previously standard open surgical repair in mortality and complication rates. Despite its success, concerns arise regarding TEVAR's long‐term effects, especially in younger BTAI patients. Key physiological changes following TEVAR include alterations in aortic size, shape, compliance and flow dynamics, leading to loss of the Windkessel effect and a consequent increased pulse wave velocity and decreased radial strain, which can contribute to the development of hypertension. These alterations also predispose patients to changes in cardiovascular flow (increased reverse systolic flow, reduced maximum velocity and altered helical flow), potentially increasing the risk of left ventricular dysfunction and coronary artery disease. Physiological changes also increase the likelihood of complications such as graft migration. Clinical outcomes of TEVAR for BTAI have generally been favourable, with significant reductions in mortality and cerebrovascular accident rates compared to open surgical repair. However, long‐term complications, including the need for re‐interventions, remain a concern, though studies suggest these are infrequent. The durability of TEVAR in younger patients, who may experience decades of device use, poses unique challenges, particularly due to the natural progression of aortic morphology over time. Therefore, adapting TEVAR to the physiological needs of younger BTAI patients is essential. Developing more compliant endografts and using shorter stents with improved materials can help minimise structural and haemodynamic changes and enhance cardiovascular outcomes, supporting the long‐term health of this vulnerable population. What is the topic of this review? How thoracic endovascular aortic repair (TEVAR) influences aortic morphology, haemodynamics and cardiovascular outcomes in younger blunt traumatic aortic injury (BTAI) patients, and the associated long‐term complications and mitigation strategies. What advances does it highlight? TEVAR alters aortic compliance and flow dynamics, increasing risks of hypertension, cardiac remodelling, and complications like endograft migration and endoleaks. However, TEVAR offers low mortality and complication rates versus open surgical repair. Strategies such as reducing stented aortic length, improving endograft materials, and precise device sizing are critical for mitigating risks, enhancing outcomes and addressing the unique physiological demands of younger BTAI patients.

In this work, we construct a three-parameter Chen modification that is flexible. The \"J shape\", \"monotonically increasing\", \"U shape,\" and \"upside down (reversed bathtub)\" hazard rate forms are all supported by the new Chen extension's hazard rate. We derive pertinent statistical features. A few distributions of the bivariate kind are generated. For evaluating the model parameters, we took the maximum likelihood estimation approach into consideration. Maximal likelihood estimators are evaluated via graphical simulations. To demonstrate the applicability of the new approach, two genuine data sets are taken into consideration and examined. The Akaike Information criterion, Bayesian Information criterion, Cramer-von Mises criterion, Anderson-Darling criterion, Kolmogorov-Smirnov test, and its related p-value are used to evaluate the new model with a variety of popular competing models.

In this paper, we introduce a new continuous log-logistic extension. Several of its properties are established. A numerical analysis for skewness and kurtosis is presented. The new failure rate can be \"bathtub or U shaped\", \"increasing\", \"decreasing-constant\", \"J shaped\", \"constant\" and \"decreasing\". Many bivariate and Multivariate type distributions are derived using the Clayton Copula and the Morgenstern family. To assess of the finite sample behavior of the estimators, we performed a graphical simulation. Some useful applications are considered for supporting the new model.

Background and aims Rectal prolapse (RP) is a debilitating condition and can cause symptoms of fecal incontinence, obstructed defecation, incomplete evacuation of the rectum, and pain. In recent years, there has been increasing evidence that prolapse development is strongly associated with pelvic hiatus (GH) size (normal 4.5 +/- 0.7). Multiple surgical studies have suggested that an enlarged pelvic hiatus may be associated with prolapse recurrence. The main aim of this study is to assess the role of combining levatorplasty -with different rectal prolapse surgeries- on recurrence rate and improvement of symptoms in patients that were treated for rectal prolapse with wide pelvic hiatus. Patients and methods Our study is a combined retrospective and prospective cohort study which included sixty patients with rectal prolapse with wide pelvic hiatus, they were divided into two groups (each group thirty patients). One group underwent rectal prolapse repair, the other group underwent rectal prolapse repair with levatorplasty. Results Levatorplasty group showed improvement in Wexner score, recurrence rate in comparison to the other group. Both groups showed similar results in postoperative pain and dyspareunia. Conclusion Rectal prolapse repair combined with levatorplasty in patients complaining of rectal prolapse with wide pelvic hiatus have better outcome mainly in decreasing recurrence rate.

BackgroundHepatic steatosis has become a major worldwide health problem, so assessment of hepatic steatosis in potential living donors is crucial prior to liver transplantation. Until now liver biopsy (LB) is considered the gold standard for diagnosing steatosis before transplantation, however steatosis assessment using imaging modalities, such as computerized tomography (CT), would be better for the donor, due its non-invasiveness. This study aimed to assess the efficacy of CT as a semiquantitaive tool for liver steatosis assessment in liver donors in comparison to liver biopsy results.MethodsThis cross-sectional study was carried out on 53 potential liver graft donors. All patients were subjected to non-contrast CT of the abdomen, tru-cut liver biopsy, and histopathological evaluation. The CT liver attenuation (CTL), the hepatic/splenic CT attenuation ratio (CTL/S) and difference between hepatic attenuation value and splenic attenuation values (CTL–S) were determined as well as the correlations of these indices and the findings of Liver biopsy (LB) were compared.ResultsAccording to the hepatosteatosis grades in the pathology results, the patients were divided into two groups: group A: 38 patients with grade 0 hepatosteatosis and group B: 15 patients with grade 1 and 2 hepatosteatosis. CTL, CTL–S, CTL/S, ratio of mean right hepatic lobe and splenic attenuation (RT/S) and ratio of mean left hepatic lobe and splenic attenuation (LT/S) were found to be effective in the diagnosis of hepatosteatosis grades at cutoff values ≤ 55.4, ≤ 8.7, ≤ 1.17, ≤ 1.1548 and ≤ 1.2971 with 80%, 80%, 73.3%, 86.7% and 86.7% sensitivity and 71.1%, 56.8%, 73.7% 71.1% and 50.0% specificity respectively. Also, CTL/S was found to be very effective in the diagnosis of grade II hepatosteatosis at cutoff values ≤ 0.9 with 100% sensitivity and 100% specificity. There was significant negative correlations between the CT indexes and degree of hepatosteatosis.ConclusionsCompared to biopsy results, CT noninvasive indices strongly predicted the presence of hepatosteatosis, which can help in avoiding the necessity for this invasive technique.

Since early 1990’s, when it was inaugurally introduced, laparoscopic splenectomy has been performed with excellent results in terms of intraoperative and postoperative complications. Nowadays laparoscopic splenectomy is the approach of choice for both benign and malignant diseases of the spleen. However some contraindications still apply. The evolution of the technology has allowed though, cases which were considered to be absolute contraindications for performing a minimal invasive procedure to be treated with modified laparoscopic approaches. Moreover, the introduction of advanced laparoscopic tools for ligation resulted in less intraoperative complications. Today, laparoscopic splenectomy is considered safe, with better outcomes in comparison to open splenectomy, and the increased experience of surgeons allows operative times comparable to those of an open splenectomy.
