Role of adiponectin, resistin and monocyte chemo-attractant protein-1 in overweight/obese asthma phenotype in children.

Background: Asthma is a chronic inflammatory disorder of the airways with diverse overlapping pathologies and phenotypes contributing to a significant heterogeneity in clinical manifestations. Obesity may modify asthma risk, phenotype, and prognosis. A suggested mechanism linking obesity and asthma is through systemic inflammation.

A functional SNP in miR-146a and genetic susceptibility to drug-resistant epilepsy.

Objectives: The study aimed to assess the relationship between the functional single nucleotide polymorphism (SNP) (rs57095329) of miR-146a, the progression of drug-resistant epilepsy (DRE), and the severity of the disease (seizure frequency) in a group of Egyptian children epilepsy patients.

Subjects And Methods: 110 Egyptian children were recruited and divided into two groups, the epilepsy patients ( = 60) and the healthy control children ( = 50). The patient's group was equally subdivided into two subgroups: drug-resistant and drug-responsive epilepsy patients.

Background: Meningitis is inflammation of the membranes enclosing the brain and spinal cord. It is a fatal disease with severe morbidity and mortality. Mannose binding lectin (MBL) encoded by MBL2 gene activates complement system through lectin pathway in innate immunity to defense against the infections.

Evaluating the Feasibility of Pro-Neurotensin and 25-Hydroxyvitamin D3 as Possible Indicators for Type 2 Diabetes Mellitus and Its Complications.

(1) Background: Type 2 diabetes mellitus (T2DM) and metabolic syndrome are associated with decreased vitamin D. In contrast, high pro-neurotensin (pro-NT) levels are linked with an increased risk of T2DM and cardiovascular disease. We aimed to determine the validity of pro-NT and 25-dihydroxy vitamin D3 levels as predictors for T2DM complications; (2) Methods: One hundred T2DM, and one hundred healthy volunteers participated in this case-control study.

The effect of high oral loading dose of cholecalciferol in non-alcoholic fatty liver disease patients. A randomized placebo controlled trial.

Non-alcoholic fatty liver (NAFLD) is one of the most common progressive metabolic disorders worldwide.

Earlier studies have revealed that vitamin D deficiency is highly prevalent in Non-alcoholic fatty liver patients that contributes to poor outcomes.

Antimicrobial Resistance Pattern, Pathogenicity and Molecular Properties of Hypervirulent (hvKp) among Hospital-Acquired Infections in the Intensive Care Unit (ICU).

Hypervirulent (hvKp) is a new emerging variant of that is increasingly reported worldwide. The variant hvKp is known to cause severe invasive community-acquired infections such as metastatic meningitis, pyogenic liver abscesses (PLA) and endophthalmitis, but its role in hospital-acquired infections (HAIs) is little known. The aim of this study was to evaluate the prevalence of hvKp among hospital-acquired (HA) infections in the intensive care unit (ICU) and to compare between hvKp and classical (cKP) regarding antimicrobial resistance pattern, virulence and molecular characteristics.

The role of lymphoid tissue SPARC in the pathogenesis and response to treatment of multiple myeloma.

Background: Despite the significant progress in the treatment of multiple myeloma (MM), the disease remains untreatable and its cure is still an unmet clinical need. Neoplastic transformation in MM is initiated in the germinal centers (GCs) of secondary lymphoid tissue (SLT) where B cells experience extensive somatic hypermutation induced by follicular dendritic cells (FDCs) and T-cell signals.

Objective: We reason that secreted protein acidic and rich in cysteine (SPARC), a common stromal motif expressed by FDCs at the origin (SLTs) and the destination (BM) of MM, plays a role in the pathogenesis of MM, and, here, we sought to investigate this role.

Estimation of immune response (IgG) to SARS-COV2 (COVID-19) after the third COVID-19 wave in Egypt, A cross-sectional Study.

Since the start of the pandemic, the number of cases has been increased rapidly. Due to asymptomatic and mild cases and restricted testing in many geographic locations, the overall number of actual COVID-19 cases is likely significantly higher than the number of verified cases. Several COVID-19-related comorbid diseases impair immune system function, which has an impact on COVID-19 responsiveness.

Faecal calprotectin in COVID-19 patients with intestinal symptoms.

Introduction: Extra-pulmonary manifestations of the Coronavirus disease of 2019 (COVID-19) have been increasingly reported, especially gastrointestinal and hepatic system dysfunction. The concern of faecal-oral transmission for COVID-19 was raised.

Aim: To study the trend of faecal calprotectin in COVID-19 patients with intestinal symptoms.

The role of miRNAs in viral myocarditis, and its possible implication in induction of mRNA-based COVID-19 vaccines-induced myocarditis.

Background: Several reports of unheeded complications secondary to the current mass international rollout of SARS-COV-2 vaccines, one of which is myocarditis occurring with the FDA fully approved vaccine, Pfizer, and others.

Main Body Of The Abstract: Certain miRNAs (non-coding RNA sequences) are involved in the pathogenesis in viral myocarditis, and those miRNAs are interestingly upregulated in severe COVID-19. We hypothesize that the use of mRNA-based vaccines may be triggering the release of host miRNAs or that trigger the occurrence of myocarditis.

Serial changes in renal indices in chronic HCV patients with and without HIV co-infection receiving sofosbuvir and tenofovir-based therapies.

Background: Sofosbuvir (SOF) is authorized for hepatitis C virus (HCV) patients. The nephrotoxicity of SOF on HCV mono-infected and HCV-human immunodeficiency virus (HIV) individuals receiving antiretroviral therapy (ART) remains controversial.

Methods: A prospective study including 159 HCV mono-infected and 124 HCV-HIV individuals (47 were ART naïve and 77 were tenofovir [TDF]-based ART) who presented with an estimated glomerular filtration rate (eGFR) ≥30 ml/min/1.

Association between Interleukin-17F 7488A/G and 7383A/G polymorphisms and susceptibility to juvenile idiopathic arthritis.

Background: Interleukin-17F (IL-17F), one of the cytokines, is crucial in the pathophysiology of juvenile idiopathic arthritis (JIA). Therefore, we aimed to determine the relation between IL17F 7488A/G and IL17F 7383A/G single-nucleotide polymorphisms and JIA susceptibility and to explain their impact on the disease activity.

Methods: Genomic DNA of 70 patients with JIA and 70 age and sex-matched controls were extracted and typed for IL17F 7488A/G and IL17F 7383A/G single-nucleotide polymorphisms, using polymerase chain reaction with sequence-specific primers method, and compared between patients and controls.

Bi-allelic loss-of-function variants in TMEM147 cause moderate to profound intellectual disability with facial dysmorphism and pseudo-Pelger-Huët anomaly.

The transmembrane protein TMEM147 has a dual function: first at the nuclear envelope, where it anchors lamin B receptor (LBR) to the inner membrane, and second at the endoplasmic reticulum (ER), where it facilitates the translation of nascent polypeptides within the ribosome-bound TMCO1 translocon complex. Through international data sharing, we identified 23 individuals from 15 unrelated families with bi-allelic TMEM147 loss-of-function variants, including splice-site, nonsense, frameshift, and missense variants. These affected children displayed congruent clinical features including coarse facies, developmental delay, intellectual disability, and behavioral problems.
