Al MAWARDI’S THEORETICAL FRAMEWORK OF THE HOLY PROPHETIC ADMINISTRATIVE AND GEOGRAPHICAL ENTITIES

The role of governors in international politics has been a subject of debate and political theories since the birth of political entities. The modern governor is a leader who leads the people and manages regional affairs. The Islamic polity was developed by the Holy Prophet (SAW), and later on was further consolidated by Khulafa e Rashideen. Governors were not only governors but also administrators, taxation officials, judges, and managers. The power delegated to governors by the central authority was tight, and they were held accountable. Governors violating precedents, set laws, or codes of conduct were punished. The most important tasks included theological leadership and military recruitment, including fiscal issues. Piety was the first requisite for a provincial Amir or Wali to continue working on the same post. Appointments made by the Holy Prophet (SAW) provided detailed guidelines for the coming generations, clarifying the functions and authorities of provincial governors. This research paper aims to analyze different dimensions and various aspects of administration during the Prophetic era

A Rare Presentation of Cardiac Aspergilloma in an Immunocompetent Host: Case Report and Literature Review

Cardiac aspergilloma is exceptionally rare with only a handful of cases reported and majority of them being in immunocompromised patients. Here, we present a case of cardiac aspergilloma involving the right and left ventricle in an immunocompetent patient that initially presented with acute limb ischemia. He was later found to have a cardiac mass with histopathological diagnosis confirming Aspergillus species. Despite aggressive medical and surgical interventions, the patient had an unfavorable outcome due to low suspicion of invasive fungal endocarditis given his immunocompetent status. Cardiac aspergilloma should remain in the differential diagnosis of immunocompetent patients as early clinical suspicion will result in early treatment and decreased mortality. Novel therapies are required to decrease mortality in the future from this fatal disease

A COMPARATIVE ANALYSIS OF THE FINANCIAL POLICIES DURING THE PIOUS CALIPHATE AND THE UMAYYADS RULE

The study of financial policies during the prophetic era, pious caliphal period, and Umayyad rule provides insights into the economic foundations of early Islamic civilization. The prophetic age prioritized fair commerce, social welfare, and charity. The pious caliphal period saw the Rashidun Caliphs consolidate administrative systems and implement financial policies for social welfare and economic justice. The Umayyad rule introduced complex financial systems and policies, influenced by pre-Islamic traditions and evolving Islamic economic principles. This analysis aims to clarify the continuity, changes, and adaptations in the economic frameworks that led to the development of Islamic culture and the lasting impact of these early financial policies on modern Islamic economic theory and practice

Murine Typhus Presenting with Acute Psychosis and Disseminated Intravascular Coagulation: A Case Report

Murine typhus is an endemic infectious disease caused by Rickettsia typhi and is transmitted by fleas. It typically causes a mild illness with symptoms of fever, rash, headache, chills, and non-specific gastrointestinal complaints. However, there have been no reported cases in the literature of murine typhus infection causing symptoms of acute psychosis and disseminated intravascular coagulation (DIC). A 30-year-old female with a history of gastric bypass and chronic pain syndrome presented to the emergency department with altered mental state and fever. She developed vivid visual hallucinations, DIC, and hypoxia with pulmonary opacities, ultimately requiring intubation. Magnetic resonance imaging (MRI) showed leptomeningeal enhancement with unremarkable cerebrospinal fluid (CSF) studies. Serum murine typhus serology came back positive. Doxycycline therapy was initiated, which resulted in complete patient recovery. This case shows that murine typhus infection may present with acute psychosis and can mimic DIC, leading to diagnostic confusion. MRI sequences may show leptomeningeal enhancement, which has never been reported before in patients with typhus. Early neurological imaging using advanced MRI sequences for patients presenting with altered sensorium, visual hallucinations, and symptoms similar to thrombotic thrombocytopenic purpura (TTP) may help with early diagnosis, decreased hospital stay, and better prognosis

An Unusual Case of Campylobacter jejuni Gastroenteritis Presenting with Acute Reversible Encephalopathy in an Immunocompetent Host

Campylobacter jejuni gastroenteritis is the most frequent organism associated with acute infectious diarrhea worldwide. (e clinical presentation involves fever, diarrhea, rigors, and myalgias. Other extraintestinal symptoms that have been described involve delirium and other neurological complications, and the most well-known is Guillain-Barr´e, where there is cross-reactivity between the gastrointestinal tract and the brain. Despite previously described multiple neurological complications, there is a lack of clinical data on the association of Campylobacter-related gastroenteritis with acute encephalopathy in immunocompetent patients. (e type of population, immunocompetent stage, and unfamiliarity with the clinical presentation makes this a challenging diagnosis for clinicians. We report a case of Campylobacter gastroenteritis associated with acute encephalopathy in an immunocompetent patient

Murine For a Bad Time: Prehospital Factor Associations With Murine Typhus Related ICU Admission

Introduction: Across South Texas rates of murine typhus related hospitalization have been on the rise (1). Murine typhus is flea borne febrile illness caused by the bacterium Rickettsia typhi. Murine typhus is easily treated with doxycycline but is commonly underdiagnosed (2). Rarely murine typhus can cause hospitalization and ICU admission (3). To gain a greater understanding of the clinical course of severe murine typhus, our team has set out to identify novel clinical findings associated severe murine typhus courses. Methods: Medical records were obtained from adults with suspected murine typhus admitted to Doctor’s Hospital at Renaissance in Edinburg, Texas, between 01/01/2010 to 05/31/2020. Authors performed manual chart review on the patients meeting the inclusion criteria and documented aspects of the patient’s medical history. Descriptive statistics were calculated with a χ2 test, were P values =0.05 were considered statistically significant. Results: We enrolled 198 hospitalized adults with suspected murine typhus in our study, 22 requiring ICU admission. No statistically significant relationships were found between ICU admission and PMH indications of: CKD, T2D, HTN, CAD or liver disease. Our results did not show significant relationships between ICU admission and sex, age, or insurance status. Conclusion: Our study did not identify statistically significant relationships between adults admitted to the ICU with suspected murine typhus and health history. The findings of our study may be useful for clinicians who practice in regions endemic to murine typhus. Our team will continue to attempt to identify clinical and laboratory findings associated with a more severe disease course of murine typhus

Effects of a high-dose 24-h infusion of tranexamic acid on death and thromboembolic events in patients with acute gastrointestinal bleeding (HALT-IT): an international randomised, double-blind, placebo-controlled trial

Background: Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma. Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding. Methods: We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries. Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to 100 mL infusion bag of 0·9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h for 24 h, or placebo (sodium chloride 0·9%). Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable. This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124. Findings: Between July 4, 2013, and June 21, 2019, we randomly allocated 12 009 patients to receive tranexamic acid (5994, 49·9%) or matching placebo (6015, 50·1%), of whom 11 952 (99·5%) received the first dose of the allocated treatment. Death due to bleeding within 5 days of randomisation occurred in 222 (4%) of 5956 patients in the tranexamic acid group and in 226 (4%) of 5981 patients in the placebo group (risk ratio [RR] 0·99, 95% CI 0·82–1·18). Arterial thromboembolic events (myocardial infarction or stroke) were similar in the tranexamic acid group and placebo group (42 [0·7%] of 5952 vs 46 [0·8%] of 5977; 0·92; 0·60 to 1·39). Venous thromboembolic events (deep vein thrombosis or pulmonary embolism) were higher in tranexamic acid group than in the placebo group (48 [0·8%] of 5952 vs 26 [0·4%] of 5977; RR 1·85; 95% CI 1·15 to 2·98). Interpretation: We found that tranexamic acid did not reduce death from gastrointestinal bleeding. On the basis of our results, tranexamic acid should not be used for the treatment of gastrointestinal bleeding outside the context of a randomised trial

Understanding the Effect of Hydro-Climatological Parameters on Dam Seepage Using Shapley Additive Explanation (SHAP): A Case Study of Earth-Fill Tarbela Dam, Pakistan

For better stability, safety and water resource management in a dam, it is important to evaluate the amount of seepage from the dam body. This research is focused on machine learning approach to predict the amount of seepage from Pakistan’s Earth and rock fill Tarbela Dam during 2003 to 2015. The data of temperature, rainfall, water inflow, sediment inflow, reservoir level collected during 2003 to 2015 served as input while the seepage from dam during this period was the output. Artificial Neural Network (ANN), Random Forest (RF), Support Vector Machine (SVM), and CatBoost (CB), have been used to model the input-output relationship. The algorithms used to predict the dam seepage reported a high R2 scores between actual and predicted values of average seepage, suggesting their reliability in predicting the seepage in the Tarbela Dam. Moreover, the CatBoost algorithm outperformed, by achieving an R2 score of 0.978 in training, 0.805 in validation, and 0.773 in testing phase. Similarly, RMSE was 0.025 in training, 0.076 in validation, and 0.111 in testing phase. Furthermore, to understand the sensitivity of each parameter on the output (average seepage), Shapley Additive Explanations (SHAP), a model explanation algorithm, was used to understand the affect of each parameter on the output. A comparison of SHAP used for all the machine learning models is also presented. According to SHAP summary plots, reservoir level was reported as the most significant parameter, affecting the average seepage in Tarbela Dam. Moreover, a direct relationship was observed between reservoir level and average seepage. It was concluded that the machine learning models are reliable in predicting and understanding the dam seepage in the Tarbela Dam. These Machine Learning models address the limitations of humans in data collecting and analysis which is highly prone to errors, hence arriving at misleading information that can lead to dam failure

A Review of Microbial Mediated Iron Nanoparticles (IONPs) and Its Biomedical Applications

Nanotechnology is a booming avenue in science and has a multitude of applications in health, agriculture, and industry. It exploits materials' size at nanoscale (1-100 nm) known as nanoparticles (NPs). These nanoscale constituents are made via chemical, physical, and biological methods; however, the biological approach offers multiple benefits over the other counterparts. This method utilizes various biological resources for synthesis (microbes, plants, and others), which act as a reducing and capping agent. Among these sources, microbes provide an excellent platform for synthesis and have been recently exploited in the synthesis of various metallic NPs, in particular iron. Owing to their biocompatible nature, superparamagnetic properties, small size efficient, permeability, and absorption, they have become an integral part of biomedical research. This review focuses on microbial synthesis of iron oxide nanoparticles using various species of bacteria, fungi, and yeast. Possible applications and challenges that need to be addressed have also been discussed in the review; in particular, their antimicrobial and anticancer potentials are discussed in detail along with possible mechanisms. Moreover, some other possible biomedical applications are also highlighted. Although iron oxide nanoparticles have revolutionized biomedical research, issues such as cytotoxicity and biodegradability are still a major bottleneck in the commercialization of these nanoparticle-based products. Addressing these issues should be the topmost priority so that the biomedical industry can reap maximum benefit from iron oxide nanoparticle-based products
