Item Evaluation of micafungin use in children; [Çocuklarda mikafungin kullanımının değerlendirilmesi](Ankara Microbiology Society, 2020) Yeşil E.; Çelebi S.; Sezgin Evim M.; Özer A.; Turan C.; Ti̇Mur D.; Çakir S.Ç.; Bülbül B.; Ener B.; Güneş A.M.; Köksal N.; Özkan H.; Sevinir B.; Düzcan Kilimci D.; Hacimustafaoğlu M.Micafungin is recommended especially in patients with liver and kidney failure and in the presence of other side effects due to antifungals apart from its known priority indications such as invasive candidiasis. The aim of this study was to evaluate the children who have received micafungin treatment. In the study, 125 children who were hospitalized in the pediatric wards and intensive care units of our hospital and had used micafungin between November 2016 and January 2019 were analyzed retrospectively. Clinical data, micafungin indication, blood values on the first and fourth days of the treatment, side effects of the drug and efficacy were evaluated. Sixty percent (75/125) of the patients were male and the mean age of all the patients were 58 ± 67 (0-215, 30) months. Approximately half of the cases (48%) had malignancy and 13% of them were premature. Sixty-two percent (n= 37) of the malignencies were hematological (27 acute lymphocytic leukemia, nine acute myeloid leukemia, one myelodysplastic syndrome) and 38% (n= 23) were oncological (six neuroblastoma, four Hodgkin lymphoma, two Non-Hodgkin’s lymphoma, five sarcomas, one hepatoblastoma, five others) malignencies. The major cause of hospitalization was sepsis (53%). The patients had several risk factors like immunosuppressive therapy (n= 68, 54%), neutropenia (n= 61, 49%), central venous catheter (n= 102, 82%), nasogastric tube (n= 63, 50%), endotracheal intubation tube (n= 49, 39%), urinary catheter (n= 14, 11%) and total parenteral nutrition (n= 81, 65%). Thirteen percent (n= 16) of the cases were post-operative patients. Candida species were cultivated in 97 clinical specimens (blood, endotracheal aspirate, sputum, urine, etc.) among 23 (18%) of the patients. Thirteen (10%) of the patients had candidemia and 62% of them were non-albicans strains. In all candidemias, strains were echinocandin susceptible, and blood cultures were negative within four days. When all the patients (n= 125) were evaluated, a significant decrease in C-reactive protein, an increase in sodium, and a decrease in alanine aminotransferase were observed on the fourth day of micafungin treatment (p< 0.05). A total of 39 (31%) patients underwent various antifungal treatments for median seven (1-60) days prior to micafungin treatment. Fourteen (36%) of these 39 patients, had elevated liver function tests (LFT), 10 (26%) of them had hypokalemia, and five (13%) of them had elevated renal function tests. Ten (26%) patients had antifungal-induced hypokalemia previously; and potassium levels were normalized after micafungin treatment (p= 0.0001). The patients for which micafungin treatment was chosen due to elevated liver function tests (n= 47, 38%), whether the antifungal induced or not; alanine aminotransferase and aspartate aminotransferase levels were decreased after micafungin treatment (p= 0.0001 and p= 0.0001, respectively). Nineteen (15%) of the patients have died within the first 30 days of micafungin treatment and one of them had candidemia. No micafungin treatment related significant side effects were observed in any of the patients. Our study showed that micafungin could be a safe and effective option in pediatric cases including newborns with high liver and kidney function tests. © 2020 Ankara Microbiology Society.

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.

The scope of this multi-centre study is to (a) assess skills of paediatric healthcare providers (HCPs) concerning two domains: (1) recognising rhythm abnormalities and (2) the use of defibrillator devices, and (b) to evaluate the impact of certified basic-life-support (BLS) and advanced-life-support (ALS) training to offer solutions for quality of improvement in several paediatric emergency cares and intensive care settings of Turkey. Methods: This cross-sectional and multi-centre survey study included several paediatric emergency care and intensive care settings from different regions of Turkey. Results: A total of 716 HCPs participated in the study (physicians: 69.4%, healthcare staff: 30.6%). The median age was 29 (27-33) years. Certified BLS-ALS training was received in 61% (n = 303/497) of the physicians and 45.2% (n = 99/219) of the non-physician healthcare staff (P <.001). The length of professional experience had favourable outcome towards an increased self-confidence in the physicians (P <.01, P <.001). Both physicians and non-physician healthcare staff improved their theoretical knowledge in the practice of synchronised cardioversion defibrillation (P <.001, P <.001). Non-certified healthcare providers were less likely to manage the initial doses of synchronised cardioversion and defibrillation: the correct responses remained at 32.5% and 9.2% for synchronised cardioversion and 44.8% and 16.7% for defibrillation in the physicians and healthcare staff, respectively. The indications for defibrillation were correctly answered in the physicians who had acquired a certificate of BLS-ALS training (P =.047, P =.003). Conclusions: The professional experience is significant in the correct use of a defibrillator and related procedures. Given the importance of early defibrillation in survival, the importance and proper use of defibrillators should be emphasised in Certified BLS-ALS programmes. Certified BLS-ALS programmes increase the level of knowledge and self-confidence towards synchronised cardioversion-defibrillation procedures. © 2021 John Wiley & Sons LtdItem SARS-CoV-2 seropositivity among pediatric health care personnel after the first peak of the pandemic: nationwide surveillance in Turkey(Elsevier B.V., 2021) Oygar P.D.; Büyükçam A.; Bal Z.Ş.; Dalgıç N.; Bozdemir Ş.E.; Karbuz A.; Çetin B.Ş.; Kara Y.; Çetin C.; Hatipoğlu N.; Uygun H.; Aygün F.D.; Törün S.H.; Okur D.Ş.; Çiftdoğan D.Y.; Kara T.T.; Yahşi A.; Özer A.; Demir S.Ö.; Akkoç G.; Turan C.; Salı E.; Şen S.; Erdeniz E.H.; Kara S.S.; Emiroğlu M.; Erat T.; Aktürk H.; Gürlevik S.L.; Sütçü M.; Aydın Z.G.G.; Atikan B.Y.; Yeşil E.; Güner G.; Çelebi E.; Efe K.; İşançlı D.K.; Durmuş H.S.; Tekeli S.; Karaaslan A.; Bülbül L.; Almış H.; Kaba Ö.; Keleş Y.E.; Yazıcıoğlu B.; Oğuz Ş.B.; Ovalı H.F.; Doğan H.H.; Çelebi S.; Çakır D.; Karasulu B.; Alkan G.; Yenidoğan İ.; Gül D.; Küçükalioğlu B.P.; Avcu G.; Kukul M.G.; Bilen M.; Yaşar B.; Üstün T.; Kılıç Ö.; Akın Y.; Cebeci S.O.; Bucak I.H.; Yanartaş M.S.; Şahin A.; Arslanoğlu S.; Elevli M.; Çoban R.; Öz Ş.K.T.; Hatipoğlu H.; Erkum İ.T.; Turgut M.; Demirbuğa A.; Özçelik T.; Çiftçi D.; Sarı E.E.; Akkuş G.; Hatipoğlu S.S.; Dinleyici E.Ç.; Hacımustafaoğlu M.; Özkınay F.; Kurugöl Z.; Cengiz A.B.; Somer A.; Tezer H.; Kara A.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)Item Epidemiological, Clinical, and Laboratory Features of Children With COVID-19 in Turkey(Frontiers Media S.A., 2021) Karbuz A.; Akkoc G.; Bedir Demirdag T.; Yilmaz Ciftdogan D.; Ozer A.; Cakir D.; Hancerli Torun S.; Kepenekli E.; Erat T.; Dalgic N.; Ilbay S.; Karaaslan A.; Erdeniz E.H.; Aygun F.D.; Bozdemir S.E.; Hatipoglu N.; Emiroglu M.; Sahbudak Bal Z.; Ciftci E.; Bayhan G.I.; Gayretli Aydin Z.G.; Ocal Demir S.; Kilic O.; Hacimustafaoglu M.; Sener Okur D.; Sen S.; Yahsi A.; Akturk H.; Cetin B.; Sutcu M.; Kara M.; Uygun H.; Tural Kara T.; Korukluoglu G.; Akgun O.; Üstündağ G.; Demir Mis M.; Sali E.; Kaba O.; Yakut N.; Kılıc O.; Kanik M.K.; Cetin C.; Dursun A.; Cicek M.; Kockuzu E.; Sevketoglu E.; Alkan G.; Guner Ozenen G.; İnce E.; Baydar Z.; Ozkaya A.K.; Ovali H.F.; Tekeli S.; Celebi S.; Cubukcu B.; Bal A.; Khalilova F.; Kose M.; Hatipoglu H.U.; Dalkiran T.; Turgut M.; Basak Altas A.; Selcuk Duru H.N.; Aksay A.; Saglam S.; Sari Yanartas M.; Ergenc Z.; Akin Y.; Duzenli Kar Y.; Sahin S.; Tuteroz S.K.; Bilen N.M.; Ozdemir H.; Senoglu M.C.; Pariltan Kucukalioglu B.; Besli G.E.; Kara Y.; Turan C.; Selbest Demirtas B.; Celikyurt A.; Cosgun Y.; Elevli M.; Sahin A.; Bahtiyar Oguz S.; Somer A.; Karadag B.; Demirhan R.; Turk Dagi H.; Kurugol Z.; Taskin E.C.; Sahiner A.; Yesil E.; Ekemen Keles Y.; Sarikaya R.; Erdem Eralp E.; Ozkinay F.; Konca H.K.; Yilmaz S.; Gokdemir Y.; Arga G.; Ozen S.; Coksuer F.; Vatansever G.; Tezer H.; Kara A.Objectives: The aim of this study is to identify the epidemiological, clinical, and laboratory features of coronavirus disease 2019 (COVID-19) in children. Methods: A retrospective study was conducted by pediatric infectious disease specialists from 32 different hospitals from all over Turkey by case record forms. Pediatric cases who were diagnosed as COVID-19 between March 16, 2020, and June 15, 2020 were included. Case characteristics including age, sex, dates of disease onset and diagnosis, family, and contact information were recorded. Clinical data, including the duration and severity of symptoms, were also collected. Laboratory parameters like biochemical tests and complete blood count, chest X-ray, and chest computed tomography (CT) were determined. Results: There were 1,156 confirmed pediatric COVID-19 cases. In total, male cases constituted 50.3% (n = 582) and females constituted 49.7% (n = 574). The median age of the confirmed cases was 10.75 years (4.5–14.6). Of the total cases, 90 were younger than 1 year of age (7.8%), 108 were 1–3 years of age (9.3%), 148 were 3–6 years of age (12.8%), 298 were 6–12 years of age (25.8%), 233 were 12–15 years of age (20.2%), and 268 cases were older than 15 years of age (23.2%). The most common symptom of the patients at the first visit was fever (50.4%) (n = 583) for a median of 2 days (IQR: 1–3 days). Fever was median at 38.4°C (38.0–38.7°C). The second most common symptom was cough (n = 543, 46.9%). The other common symptoms were sore throat (n = 143, 12.4%), myalgia (n = 141, 12.2%), dyspnea (n = 118, 10.2%), diarrhea (n = 112, 9.7%), stomachache (n = 71, 6.1%), and nasal discharge (n = 63, 5.4%). When patients were classified according to disease severity, 263 (22.7%) patients were asymptomatic, 668 (57.7%) patients had mild disease, 209 (18.1%) had moderate disease, and 16 (1.5%) cases had severe disease. One hundred and forty-nine (12.9%) cases had underlying diseases among the total cases; 56% of the patients who had severe disease had an underlying condition (p < 0.01). The need for hospitalization did not differ between patients who had an underlying condition and those who do not have (p = 0.38), but the need for intensive care was higher in patients who had an underlying condition (p < 0.01). Forty-seven (31.5%) of the cases having underlying conditions had asthma or lung disease (38 of them had asthma). Conclusions: To the best of our knowledge, this is one of the largest pediatric data about confirmed COVID-19 cases. Children from all ages appear to be susceptible to COVID-19, and there is a significant difference in symptomatology and laboratory findings by means of age distribution. © Copyright © 2021 Karbuz.Item COVID-19 disease in children presenting to the pediatric emergency department: A multicenter study with 8886 cases from Turkey(W.B. Saunders, 2022) Duman M.; Şık N.; Tekşam Ö.; Akça H.; Kurt F.; Çağlar A.A.; Yıldız L.A.; Taşar M.A.; Fidancı İ.; Yayla B.C.C.; Yılmaz D.; Güngör E.; Demir Ş.; Çokuğraş H.; Cebeci S.O.; Önal P.; Saz E.U.; Yurtseven A.; Uysalol M.; Yıldız R.; Gümüş S.; Bal A.; Bayturan S.Ş.; Zengin N.; Atik S.; Çiftdoğan D.Y.; Berksoy E.; Çiçek A.; Şahin S.; Kızıl M.C.; Kara Y.; Apa H.; Ulusoy E.; Kara A.A.; Yesil E.; Erdem M.; Turan C.; Arslanoglu S.; Duyu M.; Besli G.E.; Arslan G.; Oflu A.T.; Çeleğen M.; Buldu E.; Pişkin İ.E.; Kardeş H.; Yılmaz H.L.; Yıldızdaş D.; Gökulu G.; Çay P.; Özer U.; Güleryüz O.D.; Çolak Ö.; Güneysu S.T.Background: The aim was to evaluate the epidemiological, clinical, laboratory, and radiologic data of children with SARS-CoV-2 positivity by polymerase chain reaction (PCR) together with treatment strategies and clinical outcomes and to evaluate cases of multisystem inflammatory syndrome in children (MIS-C) in this population. Methods: This was a multicenter retrospective observational cohort study performed in the pediatric emergency departments of 19 tertiary hospitals. From March 11, 2020, to May 31, 2021, children who were diagnosed with confirmed nasopharyngeal/tracheal specimen SARS-CoV-2 PCR positivity or positivity for serum-specific antibodies against SARS-CoV-2 were included. Demographics, presence of chronic illness, symptoms, history of contact with SARS-CoV-2 PCR-positive individuals, laboratory and radiologic investigations, clinical severity, hospital admissions, and prognosis were recorded. Results: A total of 8886 cases were included. While 8799 (99.0%) cases resulted in a diagnosis of SARS-CoV-2 with PCR positivity, 87 (1.0%) patients were diagnosed with MIS-C. Among SARS-CoV-2 PCR-positive patients, 51.0% were male and 8.5% had chronic illnesses. The median age was 11.6 years (IQR: 5.0–15.4) and 737 (8.4%) patients were aged <1 year. Of the patients, 15.5% were asymptomatic. The most common symptoms were fever (48.5%) and cough (30.7%) for all age groups. There was a decrease in the rate of fever as age increased (p < 0.001); the most common age group for this symptom was <1 year with the rate of 69.6%. There was known contact with a SARS-CoV-2 PCR-positive individual in 67.3% of the cases, with household contacts in 71.3% of those cases. In terms of clinical severity, 83 (0.9%) patients were in the severe-critical group. There was hospital admission in 1269 (14.4%) cases, with 106 (1.2%) of those patients being admitted to the pediatric intensive care unit (PICU). Among patients with MIS-C, 60.9% were male and the median age was 6.4 years (IQR: 3.9–10.4). Twelve (13.7%) patients presented with shock. There was hospital admission in 89.7% of these cases, with 29.9% of the patients with MIS-C being admitted to the PICU. Conclusion: Most SARS-CoV-2 PCR-positive patients presented with a mild clinical course. Although rare, MIS-C emerges as a serious consequence with frequent PICU admission. Further understanding of the characteristics of COVID-19 disease could provide insights and guide the development of therapeutic strategies for target groups. © 2022 Elsevier Inc.Item A snapshot of pediatric inpatients and outpatients with COVID-19: a point prevalence study from Turkey(Springer Science and Business Media Deutschland GmbH, 2023) Yılmaz D.; Üstündağ G.; Büyükçam A.; Salı E.; Çelik Ü.; Avcu G.; Belet N.; Çakmak Taşkın E.; Öcal Demir S.; Birbilen A.Z.; Kılıç Ö.; Metin Akcan Ö.; Tekin Yılmaz A.; Aldemir Kocabaş B.; Hatipoğlu N.; Karbuz A.; Çakır D.; Sütçü M.; Aygün F.D.; Çelik T.; Bayturan Şen S.; Dalgıç N.; Ümit Z.; Kara S.S.; Karadağ Öncel E.; Bolat A.; Kılıç Çil M.; Turan C.; Çakıl Güzin A.; Topal S.; Esen Besli G.; Doğan G.; Şahin S.; Akın F.; Bildirici Y.; Timurtaş Dayar G.; Ergül Sarı E.; Kızmaz İşançlı D.; Kara M.; Önal P.; Aylaç H.; Lüleci D.; Yaşar B.; Dede E.; Çağlar A.; Akova S.; Afat Turgut E.; Yazıcı Özkaya P.; Kandemir Gülmez T.; Ulusoy E.; Duyu M.; Kara Y.; Çeliktaş H.; Tekeli O.; Çağlar F.; Gül D.; Oral Cebeci S.; Battal F.; Bal A.; Aygün E.; Uysalol M.; Arslan G.; Özkavaklı A.; Kızıl M.C.; Yazar A.; Aygün F.; Somer A.; Kuyucu N.; Dinleyici E.Ç.; Kara A.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.Item New records of introduced species in the Mediterranean Sea (November 2023)(Hellenic Centre for Marine Research, 2023) Langeneck J.; Bakiu R.; Chalari N.; Chatzigeorgiou G.; Crocetta F.; Doğdu S.A.; Durmishaj S.; Galil B.S.; García-Charton J.A.; Gülşahin A.; Hoffman R.; Leone A.; Lezzi M.; Logrieco A.; Mancini E.; Minareci E.; Petović S.; Ricci P.; Orenes-Salazar V.; Sperone E.; Spinelli A.; Stern N.; Tagar A.; Tanduo V.; Taşkin E.; Tiralongo F.; Trainito E.; Turan C.; Yapici S.; Zafeiridis I.; Zenetos A.This collective article presents new information about 15 introduced taxa belonging to five phyla: one Rhodophyta, one Chlorophyta, one Mollusca, one Annelida, two Arthropoda, and nine Chordata (one Ascidiacea and eight Osteichthyes).
