COVID-19 in pediatric nephrology centers in Turkey

Background/aim: There is limited data on COVID-19 disease in children with kidney disease. We aimed to investigate the characteristics and prognosis of COVID-19 in pediatric nephrology patients in Turkey. Materials and methods: This was a national, multicenter, retrospective cohort study based on an online survey evaluating the data between 11th March 2020 and 11th March 2021 as an initial step of a detailed pediatric nephrology COVID-19 registry. Results: Two hundred and three patients (89 girls and 114 boys) were diagnosed with COVID-19. One-third of these patients (36.9%) were between 10–15 years old. Half of the patients were on kidney replacement therapy: kidney transplant (KTx) recipients (n = 56, 27.5%), patients receiving chronic hemodialysis (n = 33, 16.3%) and those on peritoneal dialysis (PD) (n = 18, 8.9%). Fifty-four (26.6%) children were asymptomatic. Eighty-two (40.3%) patients were hospitalized and 23 (28%) needed intensive care unit admission. Fifty-five percent of the patients were not treated, while the remaining was given favipiravir (20.7%), steroid (16.3%), and hydroxychloroquine (11.3%). Acute kidney injury developed in 19.5% of hospitalized patients. Five (2.4%) had MIS-C. Eighty-three percent of the patients were discharged without any apparent sequelae, while 7 (3.4%) died. One hundred and eight health care staff were infected during the study period. Conclusion: COVID-19 was most commonly seen in patients who underwent KTx and received HD. The combined immunosuppressive therapy and frequent exposure to the hospital setting may increase these patients’ susceptibility. Staff infections before vaccination era were alarming, various precautions should be taken for infection control, particularly optimal vaccination coverage

Türkiye'nin Batılılığı Tartışmaları: Dış Politika ve Avrupa Birliği Üyeliği Kapsamında Karşılaştırmalı Bir Araştırma başlıklı bu proje, hem kimlik konusunda hem de dış politika yönelimleri bakımından, Türkiye ve Avrupa Araştırma Alanı'ndaki akademisyen ve araştırmacıları bir araya getirerek, bu konularda değişen ve devam eden trendleri akademik olarak araştırma kapasitesini geliştirecektir. Önerilen projenin amacı, son dönemde yalnızca Türkiye ve Avrupa Birliği (AB) ilişkilerine dair tartışmalarda değil, genel olarak Türkiye-Batı ilişkilerine dair tartışmalarda da kendini gösteren Türk dış politikasındaki yönelimleri Türkiye'nin batılılığı bağlamında yapan yurt içi ve yurt dışı değerlendirmeleri araştırmaktır. Bu araştırma tarihsel, bilimsel ve akademik bir incelemeye ve bilgiye dayanacaktır. Dolayısıyla, araştırmanın yöntemi konu ile ilgili hem Türkiye'deki hem de Avrupa'daki paydaşlar arasında sağlıklı ve etkin bir diyalog yoluyla, tarihsel, karşılaştırmalı, disiplinlerarası araştırma kapasitesini geliştirmeye yönelik ortamlar yaratmaya katkıda bulunmak prensibine dayalı olacaktır

Applicability of calf subcutaneous tissue to subcutaneous injection in young adults.

Abstract AIM: The aim of the study is to provide usage of subcutaneous tissue of lateral calf area (region of M. Gastrocnemius) in addition to the existing injection regions and to compare tissue thicknesses of the lateral upper arm, anterior and lateral thigh, anterior abdomen regions and calf regions. BACKGROUND: Subcutaneous injection (SC) is an application of 0.5cc drug with an injection (No. 25 and 8-15-18mm long) to the connective tissue under the skin. Individuals to which SC injection is frequently applied, should rotate the injection areas. METHODS: This research uses the descriptive method. One hundred and sixty-one students (aged; 20.09±2.268) were used as test subjects. Demographic data was obtained from the students who agreed to participate in the research. Body Mass Index (BMI) was calculated. Skin thickness measured using the Holtain Skinfold Caliper. SPSS 20 package software was used for statistical analysis of the data. For comparison of the tissue thicknesses between genders, the t-test was used for independent groups. In order to determine the interactions between anthropometric measurements within each other and other numerical measurements (age, length. BMI, etc.). Pearson Correlation coefficient and related P value was performed. Statistical P value is taken as 0.05. RESULTS: Consideration of subcutaneous injection applicability of the calf region depended on the injector lengths: 8mm, 15mm and 18mm, 86.3%, 59.6% and 47.8% of the population, respectively were found applicable for this region. CONCLUSIONS: The calf region could be recommended as SC injection region with an 8mm injector. According to the findings it can be said that the calf region of female genders is more applicable than male genders for SC injection. Calf region could be proposed as anticoagulation treatment

Tissue Engineered, Guided Nerve Tube Consisting of Aligned Neural Stem Cells and Astrocytes

Injury of the nervous system, particularly in the spinal cord, impairs the quality of life of the patient by resulting in permanent loss of neurologic function. The main limitation in spinal cord regeneration is the lack of extracellular matrix to guide nerves for functional recovery of the transected nerve tissue. In the present study, a tissue engineered nerve tube was prepared by wrapping neural stem cells (NSCs) on aligned fibers using a micropatterned film with astrocytes aligned along the microgrooves to support the NSCs. Initially the cell behavior on micropatterns and parallel fibers was investigated with cytoskeletal and nuclear staining, immunocytochemistry, and proliferation assay using the fiber and the film system separately. The results showed that both cells, NSCs in undifferentiated and astrocytes in differentiated form, were oriented in the direction of the guiding and support elements, the microgrooves, and the microfibers. They were able to grow and increase in number on these cell carriers. This trend was also maintained after the components were brought together in a nerve tube form and testing in coculture. The cells were able to survive and maintained their orientation in the 3D tissue engineered construct. The guided nerve tissue engineering approach tested in the present study with parallel NSCs and support cells in the tubular construct is expected to provide an appropriate environment for nerve regeneration in vivo
