Enhancing the Occurrence Variance Reporting System Implementation at one of the Hospitals of the Egyptian Universal Health Insurance.

Background: Identifying, reporting, measuring, and tracking events provide an opportunity to study system issues, motivate learning, measure the frequency and severity of events, and manage high-risk ones which refer to a safety culture that is focused on valuing the input of working staff and improving the quality of care. Aim: Enhance the implementation of the occurrence variance reporting (OVR) system at the Obstetrics and Gynecological Hospital in Port Said Governorate, Egypt. Design: A quasi-experimental research design for one group (pre-posttest) and a mixed-methods approach was conducted in this study. Method: This study was carried out at an Obstetrics and Gynecological Hospital in Port Said Governorate, Egypt. Study subjects included a convenient sample of 100 doctors and nurses. The study used three tools: OVR Knowledge, Attitude, and Practice (KAP) questionnaire, the OVR trend analysis clinical audit checklist, and barriers that hinder staff to report patient safety events through two open-ended questions. Results: Significant improvements were detected in the OVR system post-program implementation than pre-program implementation phase. A statistically significant increase in nurses' and doctors' total knowledge score from 0.74 to 3.39 and a statistically significant decrease in nurses' and doctors' total negative attitude score from 3.87 to 3.27. Also, a statistically significant increase in total practice score from 2.35 to 2.45. Conclusion: There were significant improvements in the hospital OVR system postprogram implementation than preprogram implementation. Relevance to clinical practice: To maintain performance and make sure that the original result is not lost, the health care facilities should emphasize the ongoing monthly and quarterly monitoring and analysis of data. Meetings, lectures, and training sessions are used for ongoing education.

Phenotypic spectrum and transcriptomic profile associated with germline variants in TRAF7.

PURPOSE: Somatic variants in tumor necrosis factor receptor-associated factor 7 (TRAF7) cause meningioma, while germline variants have recently been identified in seven patients with developmental delay and cardiac, facial, and digital anomalies. We aimed to define the clinical and mutational spectrum associated with TRAF7 germline variants in a large series of patients, and to determine the molecular effects of the variants through transcriptomic analysis of patient fibroblasts. METHODS: We performed exome, targeted capture, and Sanger sequencing of patients with undiagnosed developmental disorders, in multiple independent diagnostic or research centers. Phenotypic and mutational comparisons were facilitated through data exchange platforms. Whole-transcriptome sequencing was performed on RNA from patient- and control-derived fibroblasts. RESULTS: We identified heterozygous missense variants in TRAF7 as the cause of a developmental delay-malformation syndrome in 45 patients. Major features include a recognizable facial gestalt (characterized in particular by blepharophimosis), short neck, pectus carinatum, digital deviations, and patent ductus arteriosus. Almost all variants occur in the WD40 repeats and most are recurrent. Several differentially expressed genes were identified in patient fibroblasts. CONCLUSION: We provide the first large-scale analysis of the clinical and mutational spectrum associated with the TRAF7 developmental syndrome, and we shed light on its molecular etiology through transcriptome studies.

Comprehensive molecular analysis of 61 Egyptian families with hereditary nonsyndromic hearing loss.

Nonsyndromic hearing loss is an extremely heterogeneous disorder. Thus, clinical diagnostics is challenging, in particular due to differences in the etiology of hearing loss between populations. With this study, we wanted to elucidate the genetic basis of hearing loss in 61 consanguineous Egyptian families. In 25 families, linkage analysis was used as a prescreening to identify regions for targeted sequencing of candidate genes. Initially, the coding regions of 12 and later of 94 genes associated with hearing loss were enriched and subjected to massively parallel sequencing (MPS) with diagnostic yields of 36% and 75%, respectively. Causative variants were identified in 48 families (79%). They were found in 23 different genes with the majority being located in MYO15A (15.3%), SLC26A4 (9.7%), GJB2 (8.3%), and MYO7A (6.4%). As many as 32 variants were novel ones at the time of detection. Five variants were shared by two, three, or even four families. Our study provides a first survey of the mutational spectrum of deaf patients in Egypt revealing less GJB2 variants than in many European populations. It underlines the value of targeted enrichment of well-selected deafness genes in combination with MPS in the diagnostics of this frequent and genetically heterogeneous disorder.

Nigella sativa Oil and Chromium Picolinate Ameliorate Fructose-Induced Hyperinsulinemia by Enhancing Insulin Signaling and Suppressing Insulin-Degrading Enzyme in Male Rats.

In vivo and in vitro studies suggested that chromium enhances insulin sensitivity by promoting insulin receptor signaling. However, its effect on insulin clearance has not been yet identified. Nigella sativa, a widely used spice, possesses an antidiabetic activity. We, therefore, hypothesized that chromium picolinate may alter insulin clearance by modulating insulin-degrading enzyme (IDE) in insulin-resistant rats. We evaluated also the effect of Nigella sativa oil on insulin signaling and degradation with respect to chromium picolinate. To assess these hypotheses, insulin resistance was induced in 30 male Wistar albino rats through daily oral administration of high-fructose water (HFW, 20% w/v) for 45 days. These rats were then divided into three groups (n = 10/group). They were given either no treatment (control group) or Nigella sativa oil (500 mg/kg bw/day) or chromium picoloinate (200 µg/kg bw/day) orally along with HFW (20% w/v) for 45 days. Nigella sativa oil or chromium picolinate concurrent administration with HFW significantly decreased body weight, serum lipids, glucagon, insulin resistance, and hepatic IDE level but increased its mRNA expression and insulin receptor phosphorlyation as well as high-density lipoprotein cholesterol (HDL-C) level as compared to control group values, suggesting their potential as modulators for insulin signaling and clearance. However, Nigella sativa oil exerted better improvement in feeding efficacy ratio as well as the levels of glucagon, insulin, insulin resistance, hepatic IDE level and insulin receptor phosphorylation than chromium picolinate, suggesting its greater insulin sensitizing capacity. Our data, for the first time, prove that Nigella sativa oil and chromium picolinate monotherapy can reduce fructose-induced insulin resistance by reduction of hepatic IDE protein and activation of insulin receptor signaling.

Renal Presentation in Pediatric Acute Leukemia: Report of 2 Cases.

Renal enlargement at time of diagnosis of acute leukemia is very unusual. We here in report 2 pediatric cases of acute leukemia who had their renal affection as the first presenting symptom with no evidences of blast cells in blood smear and none of classical presentation of acute leukemia. The first case is a 4-year-old girl who presented with pallor and abdominal enlargement. Magnetic resonance imaging showed bilateral symmetrical homogenous enlarged kidneys suggestive of infiltration. Complete blood picture (CBC) revealed white blood count 11 × 109/L, hemoglobin 8.7 g/dL and platelet count 197 × 109/L. Bone marrow aspiration was performed, and diagnosed precursor B-cell ALL was made. The child had an excellent response to modified CCG 1991 standard risk protocol of chemotherapy with sustained remission, but unfortunately relapsed 11 month after the end of therapy. The second child was 13-month old, presented with pallor, vomiting, abdominal enlargement, and oliguria 2 days before admission. Initial CBC showed bicytopenia, elevated blood urea, creatinine, and serum uric acid, while abdominal ultrasonography revealed bilateral renal enlargement. Bone marrow examination was done and showed 92% blast of biphenotypic nature. So, biphynotypic leukemia with bilateral renal enlargement and acute renal failure was subsequently diagnosed. The patients admitted to ICU and received supportive care and prednisolone. Renal function normalized and chemotherapy was started. The child achieved complete remission with marked reduction of kidney size but, unfortunately she died from sepsis in consolidation phase of therapy. This case demonstrates an unusual early renal enlargement in childhood acute leukemia. Renal involvement of acute leukemia should be considered in child presenting with unexplained bilateral renal enlargement with or without renal function abnormalities and bone marrow examination should be included in the workup.

Intra-articular drug delivery: a fast growing approach.

Joint diseases are a leading cause of pain and disability in the adult population. Attempts have been made over the years to alleviate the pain accompanying these diseases and to decrease the incidence of joint degeneration. The utilization of the intra-articular route for the delivery of drugs and other macromolecules has recently evolved making use of the avascularity of the cartilage tissue to allow regional administration of the drug within the joint space rather than the systemic circulation. Several delivery systems such as hyaluronic acid systems, microparticles, nanoparticles, hydrogels, and thermoreversible systems have been developed in order to allow sustained drug delivery in the vicinity of the joint and to achieve high drug concentrations at the site of action. This review article focuses on the patented applications related to intraarticular delivery and sheds more light on current work involving this unique route.
