    Objective: In the early stages of any epidemic caused by new emerging pathogens healthcare personnel is subject to a great risk. Pandemic caused by SARS-CoV-2, proved to be no exception. Many healthcare workers died in the early stages of pandemic due to inadequate precautions and insufficient protection. It is essential to protect and maintain the safety of healthcare personnel for the confinement of pandemic as well as continuity of qualified healthcare services which is already under strain. Educating healthcare personnel on appropiate use of personal protective equipment (PPE) is as essential as procuring them. Material and Methods: A survey is conducted on 4927 healthcare personnel working solely with pediatric patients from 32 different centers. Education given on PPE usage were questioned and analyzed depending on age, sex, occupation and region. Results: Among four thousand nine hundred twelve healthcare personnel from 32 different centers 91% (n= 4457) received education on PPE usage. Of those who received education only 36% was given both theoretical and applied education. Although there was no differences among different occupation groups, receiving education depended on regions. Conclusion: It is essential to educate healthcare personnel appropiately nationwidely for the continuity of qualified healthcare services during the pandemic. © 2020, AVES. All rights reserved.

    Background: Understanding SARS-CoV-2 seroprevalence among health care personnel is important to explore risk factors for transmission, develop elimination strategies and form a view on the necessity and frequency of surveillance in the future. Methods: We enrolled 4927 health care personnel working in pediatric units at 32 hospitals from 7 different regions of Turkey in a study to determine SARS Co-V-2 seroprevalence after the first peak of the COVID-19 pandemic. A point of care serologic lateral flow rapid test kit for immunoglobulin (Ig)M/IgG was used. Seroprevalence and its association with demographic characteristics and possible risk factors were analyzed. Results: SARS-CoV-2 seropositivity prevalence in health care personnel tested was 6.1%. Seropositivity was more common among those who did not universally wear protective masks (10.6% vs 6.1%). Having a COVID-19-positive co-worker increased the likelihood of infection. The least and the most experienced personnel were more likely to be infected. Most of the seropositive health care personnel (68.0%) did not suspect that they had previously had COVID-19. Conclusions: Health surveillance for health care personnel involving routine point-of-care nucleic acid testing and monitoring personal protective equipment adherence are suggested as important strategies to protect health care personnel from COVID-19 and reduce nosocomial SARS-CoV-2 transmission. © 2021 The Author(s)

    This multi-center point prevalence study evaluated children who were diagnosed as having coronavirus disease 2019 (COVID-19). On February 2nd, 2022, inpatients and outpatients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were included in the study from 12 cities and 24 centers in Turkey. Of 8605 patients on February 2nd, 2022, in participating centers, 706 (8.2%) had COVID-19. The median age of the 706 patients was 92.50 months, 53.4% were female, and 76.7% were inpatients. The three most common symptoms of the patients with COVID-19 were fever (56.6%), cough (41.3%), and fatigue (27.5%). The three most common underlying chronic diseases (UCDs) were asthma (3.4%), neurologic disorders (3.3%), and obesity (2.6%). The SARS-CoV-2-related pneumoniae rate was 10.7%. The COVID-19 vaccination rate was 12.5% in all patients. Among patients aged over 12 years with access to the vaccine given by the Republic of Turkey Ministry of Health, the vaccination rate was 38.7%. Patients with UCDs presented with dyspnea and pneumoniae more frequently than those without UCDs (p < 0.001 for both). The rates of fever, diarrhea, and pneumoniae were higher in patients without COVID-19 vaccinations (p = 0.001, p = 0.012, and p = 0.027). Conclusion: To lessen the effects of the disease, all eligible children should receive the COVID-19 vaccine. The illness may specifically endanger children with UCDs. What is Known: • Children with COVID-19 mainly present with fever and cough, as in adults. • COVID-19 may specifically threaten children with underlying chronic diseases. What is New: • Children with obesity have a higher vaccination rate against COVID-19 than children without obesity. • Among unvaccinated children, fever and pneumoniae might be seen at a higher ratio than among vaccinated children. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

    Background: Antibiotic-associated diarrhea is one of the most frequent side effects of antimicrobial therapy. We assessed the epidemiological data of antibiotic-associated diarrhea in pediatric patients in our region. Methods: The prospective multi-center study included pediatric patients who were initiated an oral antibiotic course in outpatient clinics and followed in a well-established surveillance system. This follow-up system constituded inclusion of patient by the primary physician, supply of family follow-up charts to the family, passing the demographics and clinical information of patient to the Primary Investigator Centre, and a close telephone follow-up of patients for a period of eight weeks by the Primary Investigator Centre. Results: A result of 758 cases were recruited in the analysis which had a frequency of 10.4% antibiotic-associated diarrhea. Among the cases treated with amoxicillin-clavulanate 10.4%, and cephalosporins 14.4% presented with antibiotic-associated diarrhea. In the analysis of antibiotic-associated diarrhea occurrence according to different geographical regions of Turkey, antibiotic-associated diarrhea episodes differed significantly (p = 0.014), particularly higher in The Eastern Anatolia and Southeastern Anatolia. Though most commonly encountered with cephalosporin use, antibiotic-associated diarrhea is not a frequent side effect. Conclusion: This study on pediatric antibiotic-associated diarrhea displayed epidemiological data and the differences geographically in our region. © 2023, The Author(s).

    Visible light-induced self-cleaning ZnO coated-clay roofing tiles: The role of coating concentration on structural and photocatalytic properties
    (Elsevier B.V., 2024) Yavaş A.; Güneş F.; Erol M.; Sütçü M.; Özdemir E.T.
    This study introduces a novel approach involving visible light-driven ZnO-coated clay roofing tiles. The primary focus is to explore the impact of coating concentration on both the self-cleaning photocatalytic performance and physical attributes of the tiles, with a goal of contributing to environmental remediation. The research involved synthesizing various sets of tile specimens subjected to firing at 1050 °C, including pristine tiles and those coated with different concentrations of ZnO through a sol-gel dip coating process. Comparative analysis encompassed physical properties such as aesthetic appearance, stability against environmental conditions, self-cleaning properties, and the ability to degrade methylene blue (MB) as an artificial pollutant. The results demonstrated a significant enhancement in the properties of clay roofing tiles due to the coating process. Tiles with higher concentrations of ZnO exhibited proportional improvements in photocatalytic activity and physical characteristics, including reduced water adsorption and porosity, compared to the original pristine tiles. Importantly, there was no discernible impact on the mechanical performance of the tiles following the coating application. Exposure to light induced a noticeable shift in surface wettability, resulting in a state of photo-induced superhydrophilicity for all specimens. Among the various concentrations tested, the optimal coating concentration of zinc nitrate hexahydrate solution was found to be 50 mM (C50), with an apparent reaction rate of 4.06 × 10−1 h−1 and a total removal efficiency of 93.72 % after dark adsorption and 6 h irradiation. In contrast, the pristine tiles, with a degradation rate of 2.66 × 10−1 h−1, only achieved a removal efficiency of 79.98 % under the same conditions. These findings highlight the promising potential of ZnO-coated clay roofing tiles for effective environmental applications. © 2024 Elsevier B.V.

    Recycling waste polyethylene foam into fired clay bricks: A sustainable solution for lightweight and thermally efficient building materials
    (Elsevier Ltd, 2025) Yavaş A.; Kalkan Ş.O.; Sütçü M.; Gündüz L.
    Recycling polymer waste by incorporating it into building materials offers a sustainable solution to pollution and environmental challenges. This pioneering study explores the use of waste polyethylene foam (WPEF) as an additive in fired clay bricks, examining its impact on physical, thermal, mechanical, and durability properties. Bricks with 0 %–10 % WPEF content were fired at 900°C and 1000°C to assess their performance. Results show that increasing WPEF reduces bulk density significantly—up to 23.3 % at 900°C and 27.5 % at 1000°C. At 10 % WPEF, the density difference between the two temperatures narrows to 2 %, indicating 900°C as a more energy-efficient option. Thermal conductivity improves by up to 69.63 % at 900°C and 75.84 % at 1000°C, achieving a minimum value of 0.190 W/mK. While water absorption stays within limits at WPEF levels up to 7.5 %, it slightly exceeds thresholds at 10 %. Compressive strength decreases with higher WPEF content due to increased porosity, with bricks containing up to 7.5 % WPEF classified as first-class. Higher WPEF levels also reduce freeze-thaw resistance, particularly at 1000°C, due to crack formation. This study highlights WPEF's potential to produce lightweight, thermally efficient, and eco-friendly bricks with optimized WPEF content and firing conditions. © 2025 Elsevier Ltd
