RESUMEN
OBJECTIVE: Vocalizations from infants, particularly sounds associated with respiratory distress, are fundamental for observational scoring of respiratory tract issues. Listening to these infant sounds is a prevalent technique for decision-making in newborn intensive care units. Expiratory grunting, indicative of the severity and presence of potential conditions, is valuable, however, this evaluative method is subjective and prone to error. This study investigates the potential of computer-aided analysis to offer an objective scale for assessing the severity of respiratory tract problems, utilizing digital recordings of grunting sounds. METHODS: The original data set is formed with a total of 189 grunting sound segments collected from 38 infants. Multiple evaluation approaches were performed to reveal the relation between spectral characteristics of the recordings and the severity or existence of respiratory distress. RESULTS: Three spectral features were evaluated as prominently related to hospital stay duration and respiratory distress. The harmonic ratio of the recordings was graded as the most-related spectral feature that would characterize the severity. CONCLUSIONS: The potential of an innovative and objective grading approach is first investigated for replacing the human ear with a computer-aided evaluation system. The results are promising and the detected relation between expert ear-based scoring and harmonic ratio suggests that the spectral character of the grunting sounds would reflect the nature of respiratory conditions. Moreover, this study underlines those spectral features of digital grunting recordings that would be functional for automated prediction and decision-making.
RESUMEN
Vitamin B12, folate, and other micronutrients are essential for healthy growth. We hypothesized that there is a high prevalence of vitamin B12 deficiency in mothers and their newborns, and that blood serum vitamin B12 and folate levels may affect anthropometric measurements at birth. A total of 204 newborn babies and their 196 mothers were included. Blood samples of newborns and mothers were obtained for vitamin B12 (<200 pg/mL) and folate (<3 ng/mL) deficiencies. Additionally, iron and ferritin levels were measured. The mean gestational age and birth weight were 37.2 ± 2.6 (22.3-41) weeks and 3045 ± 770 (505-4525) g, respectively. All micronutrient levels in cord blood were higher than maternal levels (P = .001). A total of 96.3% of mothers and 64.5% of babies had vitamin B12 deficiency; 4% of mothers and none of the infants had folate deficiency. In total, 38.2% of mothers and 10.6% of infants had ferritin deficiency and 38.7% of mothers and 41.4% of newborns had iron deficiency. There was a negative correlation between cord vitamin B12 level and birth weight and head circumference (r = -0.21, P = .004 and r = -0.16, P = .036, respectively), whereas no correlation was found between maternal micronutrient status and anthropometric measurements of newborns. In conclusion, anthropometric measurements were unaffected by maternal levels, but vitamin B12 deficiency is very common in pregnant women and newborn babies. Mothers and their infants may benefit from early diagnosis and treatment. Awareness of vitamin B12 deficiency in pregnant women and newborns should be increased in Turkey.

BACKGROUND: Very low birth weight (VLBW) infants often demonstrate postnatal growth failure (PGF). We aimed to analyze incidence and risk factors for PGF in surviving VLBW infants hospitalized more than 28 days. MATERIALS AND METHODS: Fenton growth chart (2013) was used for Z-scores for birth weight (BW) and discharge weight. Infants with a decrease in their Z-scores at discharge >1 were considered as 'PGF group' and with a decrease >2 were considered as 'severe PGF group'. RESULTS: One hundred and forty-one of 148 (95.3%) infants had PGF, 88 of 141 (62.4%) had severe PGF. There were significant differences in gestational age, birth and discharge weight, and days to regain BW, age of first and full enteral feeding, duration of parenteral nutrition, lipid emulsions, intubation and hospitalization between groups (p < 0.05). Vasopressor treatment, nosocomial infection, patent ductus arteriosus and bronchopulmonary dysplasia rates were significantly higher in severe PGF group (p < 0.05). CONCLUSION: PGF remains a serious problem in our unit. All VLBW preterm infants should be followed for PGF.

The human major histocompatibility complex class I chain-related gene A and B (MICA and MICB) is one of the genes in chromosome 6. As MIC expression is inducible by heat, viral infection, inflammation and DNA damage, the molecules have been thought to be stress markers for the cells. We aimed to find the level of mRNA concentrations of MICA and MICB in neonates without any evidence of early onset infection.

Background/aim: Peritoneal dialysis (PD) is generally considered the practical dialysis modality for neonates in the treatment of acute kidney injury (AKI) and metabolic disturbances. The aim of this study was to evaluate the indications, complications, and outcomes of PD between January 2011 and December 2016. Materials and methods: This study included all 56 neonates that underwent PD over six years in our neonatal intensive care unit (NICU). A retrospective chart review was performed for all patients in our institution. Results: The incidence of PD was 1.32% (56/4230 patients) during this period. Mean birth weight of the patients was 2267.77 ± 1060.63 (5405050) g. Thirty-four (60.7%) patients were premature. Fourteen patients (25%) were in the postoperative period of cardiac surgery due to congenital cardiac defects, fourteen patients (25%) were diagnosed with metabolic diseases, one patient had hypoxic ischemic encephalopathy, and another patient had severe pulmonary hypertension. Conclusion: In the acute setting of a neonatal intensive care unit, PD performed in a neonate provides a technically simple method of steady fluid, solute removal, and correction of electrolyte abnormalities. A trocar catheter appears safe even in premature babies, and closed three-way stopcock system seems to be reliable at the bedside in NICUs.

Yapicioglu-Yildizdas H, Ece Ü, Sucu M, Yurdakul G, Simsek H, Özlü F. Twin reversed arterial perfusion syndrome in a monochorionic monoamniotic twin pregnancy. Turk J Pediatr 2017; 59: 724-727. Twin reversed arterial perfusion syndrome is mostly seen in monochorionic diamniotic twin pregnancies with an estimated incidence of 1/9500-11000 pregnancies. One of the twins is acardiac with various abnormalities especially with upper part of the body, and mortality is 100%. The other twin functions as a pump twin and mostly has polyhydramnios and heart failure; and mortality rate is high due to prematurity and heart failure. Herein we report a TRAP syndrome and the prognosis of pump twin who was born at 30 weeks gestational age.
RESUMEN
Idiopathic generalized arterial calcification of infancy-1 (GACI-1) is a rare and potentially lethal disease characterized by diffuse calcification of large and medium-sized arteries such as aorta, renal, pulmonary, cerebral and mesenteric arteries. Here we report two new mutations in two newborn babies with GACI-1 treated with bisphosphonates, and their progress in the first year of life.

PURPOSE: Spinal anesthesia for caesarean delivery is often associated with hypotension. This study was conducted to evaluate the effects of rapid crystalloid (Lactated Ringer's solution; LRS) or colloid (hydroxyethyl starch; HES) cohydration with a second intravenous access line on the incidence of hypotension and ephedrine requirement during spinal anesthesia for cesarean section. METHODS: We studied 90 women with uncomplicated pregnancies undergoing elective cesarean section under spinal anesthesia. Intravenous access was established in all patients with two peripheral intravenous lines, the first being used for the baseline volume infusion. Immediately after induction of spinal anesthesia, LRS (Group L) or HES (Group C) infusions were started at the maximal possible rate via the second line in groups L and C respectively. In the third group (Group E), patients received lactated Ringer's solution at a 'keep vein open' rate to maintain the double-blind nature. The incidence of hypotension, ephedrine requirements, total amount of volume and side effects were recorded. RESULTS: The incidence of hypotension was significantly greater in group E than in groups L and C, and greater in group L than in group C (p < 0.03 and p < 0.01 respectively ). The total dose of ephedrine used to treat hypotension was significantly less in groups L and C than in group E (p < 0.001 and p < 0.001 respectively). Groups L and C received similar infusion volumes and doses of ephedrine. CONCLUSIONS: Giving either LR or HES coloading via a second IV line caused less hypotension and required less use of ephedrine compared to no coloading. There were no maternal or neonatal side effects.
