    Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Güniz KüçükgüzelDepartment: Pharmaceutical ChemistryAim: The research conducted in recent years show that MetAP2 is one of the important enzymes involved in the development of cancer. Based on these studies, it has been found appropriate to select this enzyme as a macromolecular target. It has been reported in the literature that molecules having thioether and 1,2,4-triazole ring, especially hydrazide-hydrazone structure, show strong anticancer activity.Materials and Mehtods: Naproxen ((S)-2-(6-methoxy-2-naftyl)propionic acid) was chosen as a starting compound for the synthesis of designed molecules. Naproxen ester (compound 1) was synthesized with metanolic solution of naproxen and sulphuric acid as a catalizor. Naproxen hydrazide (compound 2) was synthesized with naproxen ester and hydrazine hydrate in methanol. Compound 2 was treated with 4-fluorophenyl isothiocyanate for the synthesis of thiosemicarbazide compound (compound 3). The thiosemicarbazide compound 3 was then treated with 4N NaOH resulting with the synthesis of 1,2,4-triazole-3-thione compound (compound 4). Thioester compound (compound 5) was synthesized with ethyl α-bromoacetate, K2CO3/acetone and with the presence of compound 4. Thiohydrazide compound (compound 6) was then synthesized with compound 5 and hydrazine-hydrate in ethanolic medium. Compound 6 was then converted to our target compounds (7a-z) with the addition of substituted aldehydes.Findings: The compounds 5, 6, 7a-z, which are the naproxen hybrid molecules, are the original compounds synthesized in this work.

    In this study, new Tetracaine thiosemicarbazide derivatives were designed, synthesized, and evaluated for their antimicrobial activity. These compounds (2a-l) were characterized using spectroscopic (H-1-C-13 NMR, FT-IR and HR-MS) methods and tested for their antimicrobial activity against various Gram-positive and Gram-negative bacterial strains (Staphylococcus aureus ATCC 29213: Enterococcus faecium ATCC 29212; Escherichia coli ATCC 25922; Pseudomonas aeruginosa ATCC 27853), and fungus (Candida albicans ATCC 10231). The microbroth dilution method was utilized for the determination of the minimum inhibitory concentration (MIC) values of novel molecules. The antimicrobial activities of the molecules were found to have a wide range of MIC values with 4-256 mu g/mL. Among the synthesized molecules, compound 2 h (2-[4-(butylamine)benzoyl]-N-(3,5-bistrifluoromethylphenyl)hydrazine-1-carbothioamide) showed the best MIC value for 4 (mu g/mL) to S. aeurus isolate and 8 (mu g/mL) to C. albicans, respectively. Compounds 2e (2-[4-(butylamine)benzoyl]-N-(2-fluorophenyl)hydrazine-1-carbothioamide) and 2f (2-[4-(butylamine)benzoyl]-N-(4-nitrophenyl)hydrazine-1-carbothioamide) showed moderate activity to C. albicans and S. aeurus with a 16 (mu g/mL) MIC value
