Evaluating the potential mediating role of ADAMTS13 activity in the relationship between obesity and the severity of COVID-19: A retrospective cohort study.

Obesity and low enzyme A disintegrin and metalloproteinase with thrombospondin type-1 motif-13 (ADAMTS13) activity have been linked to poor coronavirus disease 2019 (COVID-19). Given that obesity may influence ADAMTS13 activity, it is feasible; however, it remains unclear whether ADAMTS13 activity acts as a mediator between obesity and COVID-19 outcomes. We investigated the link between body mass index (BMI) and COVID-19 outcomes, using ADAMTS13 activity as a mediator.

Impact of aerobic and resistance training on fatigue, quality of life, and physical activity in prostate cancer patients: a systematic review and meta-analysis.

Background: Prostate cancer (PCa) is a prevalent cancer with significant morbidity and mortality rates. In most cases, PCa remains asymptomatic until advanced disease manifests with symptoms, such as benign prostate hyperplasia. Timely detection and better management have improved overall survival in patients with PCa, and fatigue, reduced physical activity, and impaired quality of life (QoL) remain major challenges that impact daily life.

Interleukin-6 and the determinants of severe COVID-19: A retrospective cohort study.

Cytokines, notably interleukin-6 (IL-6), increase considerably in patients with severe corona virus disease 2019 (COVID-19). This vigorous immune response may cause end-organ failure or death; hence, measuring IL-6 in the context of patient characteristics may help predict outcomes and encourage early comprehensive therapy. This study investigated the association between serum IL-6 levels, COVID-19 severity, and demographic, clinical, and biochemical characteristics.

Intestinal tuberculosis and inflammatory bowel disease; the usual challenging differential diagnoses: A case report.

Intestinal Tuberculosis (TB) is a very rare presentation of TB, presenting with a nonspecific symptom that mimics Crohn's disease, making diagnosis challenging. We present a case of intestinal tuberculosis in a 37-year-old female who had long-term abdominal pain and diarrhea and showed all the signs of inflammatory bowel disease (IBD) during a thorough clinical, endoscopic, radiologic, and histologic examination. Seven months of right mid- and lower-abdominal discomfort brought a 37-year-old woman to our hospital with pain, diarrhea, bloating, and tiredness worsening after meals.

Impact of Growth Temperature of Lead-Oxide Nanostructures on the Attenuation of Gamma Radiation.

Chemical bath deposition (CBD) technique is utilized to grow lead-oxide (PbO) nanostructures (NSs) over PbO seed fabricated by physical vapor deposition (PVD) method on glass substrates. The effect of growth temperatures 50 and 70 °C on the surface topography, optical properties, and crystal structure of lead-oxide NSs has been studied. The investigated results suggested that the growth temperature has a huge and very considerable influence on the PbO NS, and the fabricated PbO NS has been indexed as the PbO polycrystalline tetragonal phase.

Fabrication and Characterization of High-Quality UV Photodetectors Based ZnO Nanorods Using Traditional and Modified Chemical Bath Deposition Methods.

Ultraviolet (UV) photodetectors (PDs) based on high-quality well-aligned ZnO nanorods (NRs) were fabricated using both modified and conventional chemical bath deposition (CBD) methods. The modified chemical bath deposition (M-CBD) method was made by adding air bubbles to the growth solution during the CBD process. The viability and effectiveness of M-CBD were examined by developing UV PDs based on ZnO NRs.

A severe refractory COVID-19 patient responding to convalescent plasma; A case series.

Introduction: Although some medicines are under research, currently, no specific antiviral drug has been approved to target 2019 novel coronavirus. In this report two severe cases of 2019 novel coronavirus disease (COVID-19) patients have been described who received convalescent plasma (CP).

Case Report: Two male cases (a 46-year-old and a 56-year-old) after being diagnosed with severe COVID-19, they deteriorated despite supportive care and antiviral therapy.

Predominance and association risk of subtype I in colorectal cancer: a case control study.

Background: a genetically diverse intestinal parasite with controversial pathogenic potential, has increasingly been incriminated for diarrheal illness in immunocompromised individuals including colorectal cancer (CRC) patients. The aim of the current study was to assess the possible association between infection and CRC condition in Makkah, Saudi Arabia (KSA).

Methods: Stool samples were collected from 80 non-cancer (NC) and 138 cancer subjects including 74 CRC patients and 64 patients with other cancers outside gastrointestinal tract (COGT).

PREVALENCE OF SOME GASTRO-INTESTINAL PARASITES IN DIABETIC PATIENTS IN TANTA CITY, GHARBIA GOVERNORATE, EGYPT.

It is well known that diabetes mellitus affects the immune system negatively through various ways. Diabetic patients are also considered as the immunocompromised group of patients. Infections with intestinal parasites are uncommon to cause high morbidity or mortalilty to man, but they are risky to diabetic patients.

Prevalence of Helicobacter pylori infection among adult patients with different gastrointestinal parasites in Tanta City district.

This study determined the prevalence of Helicobacter pylori infection in patients with different gastrointestinal symptoms. Two hundred and six patients were collected from outpatient clinic of medical department from March to June 2014. The age was ranged between 15 years old up to 60 years old.

A wireless emergency telemedicine system for patients monitoring and diagnosis.

Recently, remote healthcare systems have received increasing attention in the last decade, explaining why intelligent systems with physiology signal monitoring for e-health care are an emerging area of development. Therefore, this study adopts a system which includes continuous collection and evaluation of multiple vital signs, long-term healthcare, and a cellular connection to a medical center in emergency case and it transfers all acquired raw data by the internet in normal case. The proposed system can continuously acquire four different physiological signs, for example, ECG, SpO2, temperature, and blood pressure and further relayed them to an intelligent data analysis scheme to diagnose abnormal pulses for exploring potential chronic diseases.

Growth kinetics, antigen profiling, and proteinase activity of Egyptian Trichomonas tenax isolates derived from patients having oral infections.

The role of Trichomonas tenax as a pathogen had been clearly implicated in various pathological processes that arise outside the boundaries of the mouth. Although a relationship between the increased occurrence of this protozoan and progression of periodontal disease has been demonstrated, the ability of T. tenax in causing oral infections and the precise mechanism of tissue damage is not well known.

Experimental study for early diagnosis of prepatent schistosomiasis mansoni by detection of free circulating DNA in serum.

Sensitive and specific diagnostic methods of schistosomiasis at an early stage of infection are crucial to avoid irreversible pathological reactions induced by eggs. This study aimed to evaluate the PCR technique for detection of free circulating Schistosoma mansoni DNA in serum in the early prepatent period in experimentally infected mice, in comparison to the commonly used indirect hemagglutination assay (IHA) for the detection of bilharzial antibody and stool examination. Sixty-four mice were experimentally infected with S.

In vitro amoebicidal activity of ethanol extracts of Arachis hypogaea L., Curcuma longa L. and Pancratium maritimum L. on Acanthamoeba castellanii cysts.

Acanthamoeba castellanii causes amoebic keratitis which is a painful sight-threatening disease of the eyes. Its eradication is difficult because the amoebas encyst making it highly resistant to anti-amoebic drugs, but several medicinal plants have proven to be more effective than the usual therapy. This study aimed to evaluate the in vitro amoebicidal activity of ethanol extracts of Arachis hypogaea L.
