Background/aim: This study aimed to analyze the serum melatonin levels and changes in sleep patterns in pediatric patients with coronavirus disease 2019 (COVID-19). Materials and methods: This study was designed as a descriptive, cross-sectional study. Serum melatonin levels and sleep parameters of children with the diagnosis of COVID-19 who had mild and moderate disease (i.e., COVID-19 group) were compared with those of children admitted with non-COVID-19 nonspecific upper respiratory tract infection (i.e., control group). The sleep disturbance scale for children (SDSC) questionnaire was applied to the participants› primary caregivers to analyze their sleep patterns at present and six months before symptom onset and to investigate the impact of COVID-19 on sleep patterns. Results: The entire study cohort consisted of 106 patients. The COVID-19 group included 80 patients, while the control group consisted of 26 patients. The mean serum melatonin levels were 136.72 pg/mL and 172.63 pg/mL in the COVID-19 and control groups, respectively (p = 0.16). There was no significant difference between the groups in terms of 6 subcategories of the SDSC questionnaire regarding the present time and 6 months before symptom onset. The total SDSC scores were also similar in two different evaluation time points described above (p = 0.99). Conclusions: We conclude that COVID-19 did not impact the sleep parameters of children. Serum melatonin levels of all patients were higher than the reference range; however, they were higher in the non-COVID-19 patient group than the COVID-19 group. Since serum melatonin levels were higher than the reference values in children with COVID-19, and this disease is significantly less morbid in children, melatonin may have protective effects against COVID-19.

Our aim was to investigate whether Antimullerian Hormone (AMH), complete blood count (CBC), Homeostasis model assessment (HOMA-IR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and weight gain have any diagnostic value for the prediction of cardiovascular disease (CVD) in obese and non-obese pregnant patients. A prospective, case-control study was carried out, including 187 patients (93 obese, and 94 non-obese). CVD risk for each patient was evaluated according to the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (ACC/AHA). A multivariate logistic regression model was used to identify the independent risk factors of CVD in obese and non-obese patients. The obese patients had significantly lower levels of AMH when compared to the non-obese ones (p = .002). Insulin, HOMA-IR, HbA1c, and SBP were significantly higher in obese patients than non-obese ones (p < .001, p < .001 and p = .001, respectively). Age, SBP, and decreased AMH levels had significantly associated with risk factors of CVD in the obese group (p = .001, p = .002, and p = .049, respectively). Our study suggests that decreased AMH levels, increased age, and SBP are associated with CVD in obese patients. AMH may be used to evaluate CVD risk in advanced aged, obese patients.IMPACT STATEMENTWhat is already known on this subject? Obesity is one of the most common medical complications of pregnancy. Obesity increases maternal complications such as preeclampsia, caesarean rate, cardiovascular disease, obesity, and diabetes after pregnancy; and neonatal complications including macrosomia, hypoglycaemia, hyperbilirubinemia, delivery trauma, shoulder dystocia, and adult-onset obesity, and diabetes. Obese patients have lower serum AMH levels.What the results of this study add? A significant relationship between AMH levels and CVD risk in obese pregnant women was observed.What are the implications of these findings for clinical practice and/or further research? Based on this finding, we concluded that decreased AMH levels are predictive for CVD in obese pregnant women. [ABSTRACT FROM AUTHOR]

Amaç: Hemoglobinopatiler, globin fonksiyonlarını bozan bir grup hastalıktır. HPLC, hemoglobinopati taramalarında tüm dünyada en sık kullanılan tekniktir. Çalışmada, Türkiye'de bir üçüncü basamak hastane laboratuvarında 3 yıllık retrospektif hemoglobinopati sıklığı değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: Üniversite hastanemize başvuran 2461 hastanın 3 yıllık laboratuvar ve hastane kayıtları incelenmiştir. Hemoglobinopati taramasında Tosoh G8 HPLC cihazı kullanılmıştır Bulgular: HbA2%3,5 olan 668, %3,5HbA2%4 olan 19 sonuç saptanmıştır.19 sonuçtan 10'u betatalasemi minör olarak kabul edilmiştir. HbA2 %4 olan 649 sonuç vardır ve sonculara göre 602 hasta beta-talassemi minör olarak kabul edilmiştir. HbA2 düzeylerine göre, hastaların %25'i beta-talasemi minör olarak değerlendirilmiştir. HbF%2 olan 391 hasta saptanmış ve HbA2%3,5 olan 138 kayıt ayrıntılı incelemeye alınmıştır. Varyant analizi veri kümesi, 53 hasta içermektedir. HbA2%3,5 ve HbF%2 olan, varyant pikleri mevcut kayıtlar incelenmiş ve 28 vaka saptanmıştır. En sık görülen Hb varyantları sırasıyla HbH, HbS, HbD, HbC, HbE ve HbO-Arab'dır. Sonuç: Çalışmada en sık varyantlar sırasıyla HbH, HbAS, HbAD, HbAC, HbAE ve HbO-Arab olarak bulunmuştur. Beta talasemi minör sıklığı ülkemizin gelen popülasyonundan yüksek olarak %25 bulunmuştur. Özellikle hematolojik malignensiler, herediter sferositoz ve demir eksikliği anemisi gibi eşlik eden durumlar hemoglobinopati değerlendirmesinde akılda tutulmalıdır., Objective: Hemoglobinopathies are an array of disorders that affect hemoglobin (Hb) function. HPLC is by far the most common technique used for detection of hemoglobinopathies worldwide. The aim of this study is to evaluate 3-year retrospective data of a tertiary hospital in Turkey according to prevalence of hemoglobinopathies. Material and Methods: A three-year data of 2461 patients admitted to our university hospital laboratory were assessed by scanning laboratory and hospital records. Tosoh G8 HPLC instrument was used for screening. Results: 668 results with HbA23.5% and 19 results with 3.5% HbA2 4% were detected. 10 of 19 patients were considered as beta-thalassemia. Number of patients with HbA2 4% were 649 and 602 of them were assessed as beta-thalassemia-minor. 25% of patients were assessed as beta-thalassemiaminor, based on HbA2 levels. 391 patient results were found to be HbF2% and 138 of them with HbA23.5% were further investigated. Variant analysis dataset contains 53 patients. Samples with HbA23.5% and HbF2% showing variant peaks were scanned and 28 cases were detected. The most common variants were found to be HbH, HbS, HbD, HbC, HbE and HbO-Arab, respectively. Conclusion: In this study, the most common variants were found to be HbH, HbAS, HbAD, HbAC, HbAE and HbO-Arab, respectively. Moreover, the frequency of beta-thalassemia minor was found as 25% which is higher than general population prevalence of our country. Accompanying diseases especially hematological malignancies, hereditary spherocytosis and IDA should be kept in mind during evaluating hemoglobinopathy analysis.

Otoimmün hepatit, kronik inflamatuvar hepatoselüler bir hastalık olup hepatomegali, otoantikorların varlığı ve poliklonal hipergamaglobulinemi ile karakterizedir. Kronik bir karaciğer hastalığı olan otoimmün hepatitin komplikasyonlarından biri fibrozistir. Hepatik fibrozis, karaciğer dokusunda hücre dışı matriks bileşenlerinin aşırı birikimi ve histolojik olarak yeniden biçimlenmesi sonucu ortaya çıkan ve uzun dönemde karaciğerde işlev bozuklukları ve doku hasarına yol açan patolojik bir durumdur. Karaciğer fibrozisinin değerlendirmesinde altın standart yöntem olarak karaciğer biyopsisi önerilmektedir. Ancak komplikasyonları ve sık kullanıma uygun olmaması nedeniyle son yıllarda karaciğer fibrozisinin değerlendirilmesi için girişimsel olmayan yöntemler geliştirilmektedir. ELF (enhanced liver fibrosis) testi, karaciğerde fibrozis oluşumunda rol alan hücre dışı matriks metabolizmasını yansıtan belirteçlerden oluşan bir biyokimyasal test panelidir. ELF test paneli, üç parametreden oluşur: Prokolajen-III N-terminal propeptidi (PIIINP), metalloproteazların doku inhibitörü-1 (TIMP-1) ve hyaluronik asit (HA). Serum düzeyleri ölçülen bu parametreler, istatistiksel olarak geliştirilmiş ELF puanını hesaplamak için kullanılır. Bu çalışmada, otoimmün hepatitli hastalarda karaciğerde fibrozis düzeyinin değerlendirilmesi için kullanılan ELF testinin tanısal değerinin karaciğer biyopsisi ile karşılaştırılması amaçlanmıştır. Çalışmaya toplam 46 hasta dahil edildi. Son bir yıl içinde karaciğer biyopsisi yapılmış olan hastalardan ELF testi için kan örneği alındı. Hasta örnekleri Siemens ADVIA Centaur XP cihazında çalışıldı ve ELF puanları hesaplandı. Karaciğer biyopsileri, METAVIR evreleme sistemine göre incelendi. Hastalar, METAVIR evrelerine göre F0-F1 yok-hafif fibrozis (Grup 1) ve F2-F3-F4 orta-ağır fibrozis (Grup 2) olarak iki gruba ayrıldı. Hastaların % 19,6'sı Grup 1, % 80,4'ü grup 2'de yer aldı. ELF puanı ortalamaları Grup 1 için 8,62±1,05, Grup 2 için 10,60±1,39 olarak bulundu ve gruplar arası farkın istatistiksel olarak anlamlı olduğu gözlendi (p
