BK Virus Infections and Hemorrhagic Cystitis in Allogeneic Hematopoietic Stem Cell Transplant Recipients.

BK virus (BKV) associated with hemorrhagic cystitis (HC) is the most important complication that develops after hematopoietic stem cell transplantation (HSCT) in patients with hematological malignancies. This study aims to investigate BKV infections and HC in pediatric patients after allogeneic hematopoietic stem cell transplantation. Between November 2018 and November 2019, a total of 51 patients between the ages of 11 months and 17 years were included in the study. BKV Bosphore ® v1 quantification kit (Geneworks Anatolia, Turkey) was used for the detection of BKV DNA in urine and blood samples. Among the total of 51 patients, the incidence of BKV infection was found to be 86.3%. Allogeneic HSCT was performed in 40 patients and autologous HSCT in 11 patients. BK viruria and/or viremia were detected in 85% (44) of patients who underwent allogeneic HSCT and in 90% in the autologous group. High-level BK viruria (>107 copies/mL) was found in 41% (9) of 22 patients who were BKV positive before transplantation, while in 27.5% (8) of 29 patients who were BKV negative before transplantation; thus, BKV positivity before transplantation was considered a risk factor for high-level BK viruria. Acute GVHD developed in 6 of 40 patients in the allogeneic group. HC was prevented in 12 (67%) of 18 patients who received preemptive treatment, while HC developed in 6 (33%). HC occurred at a median of 35 days (17-49 days) post-transplant. Despite preemptive treatment, 6 (15%) patients who developed HC associated with BKV were in the allogeneic group but not in the autologous group. Of these patients with HC, 5 received a myeloablative treatment regimen, and 1 patient was given a reduced-intensity treatment regimen. The viral load in urine was found to be 107-9 copies/mL within 2 weeks before the development of HC and has been identified as a prognostic indicator. In conclusion, early diagnosis of viral infections by monitoring BKV viral load in HSCT patients will be effective in preventing the progression of complications such as BKV-associated HC by providing timely initiation of preemptive treatment.

Lessons learned from implementing SNAP-Ed in a nursing/K-8 partnership school during the pandemic.

The COVID-19 pandemic had forced schools and school-based partnerships in the US to re-imagine extracurricular activities while schools were closed for in-person learning. We highlight lessons learned from implementing the Supplemental Nutrition Assistance Education Program (SNAP-Ed) virtually, a nutrition education program to improve nutrition literacy and skills among children, in a Maryland School of Nursing/K-8 Partnership school amid in-person school closures.

Structure based drug design of Pim-1 kinase followed by pharmacophore guided synthesis of quinolone-based inhibitors.

Over expression of Human phosphatidyl inositol mannoside kinases isoform 1 (Pim-1 kinase) has been reported in several leukemia and solid tumors. Our continuous interest to reveal the secrecies of the mysterious Pim-1 kinase binding pocket has led us to employ a structure based drug design procedure based on receptor-ligand pharmacophore generation protocol implemented in Discovery Studio 4.5 (DS 4.5). Subsequently, we collected 104 crystal structures of Pim-1 kinase from the Protein Data Bank (PDB) and used them to generate pharmacophores based on the anticipated co-crystallized ligand-Pim 1 kinase receptor interactions. All selected pharmacophoric features were enumerated and only those that had corresponding valuable receptor-ligand interactions were retained. This was followed by modeling all pharmacophore combinations and scoring them according to their Receiver Operating Characteristic (ROC) curve analysis parameters as well as a DS.4.5 built-in Genetic Function Algorithm (GFA) validating model. Accordingly, 111 pharmacophores resulted with acceptable ROC performances; 1XWS_2_04, 2BIK_2_06, and 1XWS_2_06 (ROC AUC value of: 0.770, 0.743 and 0.741 respectively) were the best pharmacophores. These pharmacophores were employed to guide the synthesis of new series of 7-[(2-Carboxyethyl)amino]-1-substituted-6-fluoro-8-nitro-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid and their reduced 8-amino derivatives. The synthesized compounds were later evaluated for their Pim-1 kinase inhibitory potencies. Of which the most potent illustrated an IC50 value of 0.29µM against Pim-1 kinase.

Agomelatine Monotherapy for Autism-A Case Report.

ASD is commonly associated with a host of challenging behaviours. Pharmacotherapy is indicated if psycho-social and educational interventions fail. Atypical antipsychotics have the strongest evidence-base so far, with both risperidone and aripiprazole are FDA-approved. Unfortunately, their use is fraught with metabolic and neuro-hormonal side effects. Here, authors report on a case of ASD/mild ID with behavioural dyscontrol that failed multiple psychotropic trials and ultimately responded favourably to agomelatine monotherapy. This was achieved with excellent tolerability. This might open new venues in such complicated cases.

Evaluation of Self-Medication with Antibiotics in Primary Care Clinics in Palestine.

Background: Antibiotics are highly effective medications and essential in curing infectious diseases; however, their inappropriate use, such as self-medication, is a significant factor in developing antimicrobial resistance. Objective: This study aimed to evaluate the level of antibiotic self-medication among patients who visited primary care clinics in Palestine. Methods: Data were collected via a self-administered questionnaire, either printed or electronically, using google forms (Google Inc., USA). The sample size needed to provide a 95% confidence level and 5% margin error and assuming a prevalence of 50% of SM with antibiotics was 377 patients. A total of 700 questionnaires were randomly distributed to patients aged 18 years or older. However, 87 were excluded due to duplication, incomplete responses, or participants under 18 years old. Finally, 423 patients were included in this study, with 254 patients completing the electronic Google Forms and 181 completing the written survey. The questionnaire consists of patients' demographics, antibiotics knowledge, and self-medication behavior. In addition, descriptive statistics and knowledge scales were performed using SPSS 22 IBM to measure and assess the scope of the problem and find the association between self-medication demographics, education, and socioeconomic status. Results: Approximately 50% of participants reported self-medication with antibiotics, with a very high use among participants with medical knowledge. Most people have adequate awareness of antibiotics, whereas out of 423 respondents, (40.2%, n = 170) had GKL, (50.4%, n= 213) had AKL, and only (9.5%, n=40) presented PKL. The primary source for self-treatment with antibiotics was community pharmacies (87.1%, n=223), whereas (14.1%, n=36) got antibiotics from family and friends. Convenience, easy access, and experience with community pharmacists contributed to self-medications. The most commonly used antibiotic for self-medication was amoxicillin/clavulanic acid. Conclusion: Self-medication with antibiotics is a common practice in Palestine, regardless of socioeconomic or educational status. Patients' educations about complications from inappropriate use and the possibility of side effects are essential steps to decrease patients' demands for antibiotics. Furthermore, compliance and adherence of community pharmacists in dispensing antibiotics only with a prescription is necessary.
