Effect of vitamin D supplementation during pregnancy on neonatal mineral homeostasis and anthropometry of the newborn and infant

Hypovitaminosis D is common in India. In the present prospective partially randomised study of vitamin D (D₃) supplementation during pregnancy, subjects were randomised in the second trimester to receive either one oral dose of 1500 μg vitamin D₃ (group 1, n 48) or two doses of 3000 μg vitamin D₃ each in the second and third trimesters (group 2, n 49). Maternal 25-hydroxyvitamin D (25(OH)D) at term, cord blood (CB) alkaline phosphatase (ALP), neonatal serum Ca and anthropometry were measured in these subjects and in forty-three non-supplemented mother-infant pairs (usual care). Median maternal 25(OH)D at term was higher in group 2 (58·7, interquartile range (IQR) 38·4-89·4 nmol/l) v. group 1 (26·2, IQR 17·7-57·7 nmol/l) and usual-care group (39·2, IQR 21·2-73·4 nmol/l) (P = 0·000). CB ALP was increased (>8.02 μkat/l or >480 IU/l) in 66·7 % of the usual-care group v. 41·9 % of group 1 and 38·9 % of group 2 (P = 0·03). Neonatal Ca and CB 25(OH)D did not differ significantly in the three groups. Birth weight, length and head circumference were greater and the anterior fontanelle was smaller in groups 1 and 2 (3·08 and 3·03 kg, 50·3 and 50·1 cm, 34·5 and 34·4 cm, 2·6 and 2·5 cm, respectively) v. usual care (2·77 kg, 49·4, 33·6, 3·3 cm; P = 0·000 for length, head circumference and fontanelle and P = 0·003 for weight). These differences were still evident at 9 months. We conclude that both 1500 μg and two doses of 3000 μg vitamin D₃ had a beneficial effect on infant anthropometry, the larger dose also improving CB ALP and maternal 25(OH)D.

Newborn screening for congenital hypothyroidism, galactosemia and biotinidase deficiency in Uttar Pradesh, India

ObjectiveTo assess feasibility and recall rates for newborn screening for congenital hypothyroidism, galactosemia and biotinidase deficiency in a predominantly rural and inner city population in and around the City of Lucknow in Uttar Pradesh, India.DesignProspective observational study.SettingTwo tertiary-care and 5 district hospitals in and around Lucknow.ParticipantsAll babies born in above hospitals during the study period.MethodsHeel prick samples were collected after 24 hours of life. Dried blood spot TSH, total galactose and biotinidase were assayed by immunofluorometry. Age related cut-offs were applied for recall for TSH. For galactosemia and biotinidase deficiency, manufacturer-suggested recall cut-offs used initially were modified after analysis of initial data.Main outcome measureRecall rate for hypothyroidism, galactosemia and biotinidase deficiency.ResultsScreening was carried out for 13426 newborns, 73% of all deliveries. Eighty-five percent of those recalled for confirmatory sampling responded. Using fixed TSH cut off of 20 mIU/L yielded high recall rate of 1.39%, which decreased to 0.84% with use of age-related cut-offs. Mean TSH was higher in males, and in low birth weight and vaginally delivered babies. Eleven babies had congenital hypothyroidism. Recall rates with modified cut-offs for galactosemia and biotinidase deficiency were 0.32% and 0.16%, respectively.ConclusionAn outreach program for newborn screening can be successfully carried out in similar socio-cultural settings in India. For hypothyroidism, the high recall rate due to early discharge was addressed by age-related cut-offs.

High Frequency Oscillatory Ventilation versus Synchronized Intermittent Mandatory Ventilation in Preterm Neonates with Hyaline Membrane Disease: A Randomized Controlled Trial.

This randomized controlled study was conducted to compare the efficacy and safety of High frequency oscillatory ventilation (HFOV) and Synchronized intermittent mandatory ventilation (SIMV) in preterm neonates with hyaline membrane disease requiring ventilation. The ventilation strategy in both the groups included achieving optimal lung recruitment and targeted blood gases. 49 patients received HFOV and 61 SIMV. The baseline characteristics were similar in both the groups. HFOV group demonstrated better early oxygenation, enabled reduction in oxygenation index (OI) within 24 h of ventilation (difference in mean OI at 1, 6, & 24 h of ventilation: P=0.004 in HFOV, and 0.271 in SIMV group). Duration of hospital stay was shorter in HFOV group (P=0.003). The complication rate and survival were similar in two groups.

Multidrug resistant Gram-negative bacilli from neonatal septicaemia at a tertiary care centre in North India: A phenotypic and genotypic study

for meropenem and colistin,[2] phenotypic tests for AmpC production (by cefoxitin disc,[3] disc antagonism test,[3] boronic acid inhibition test[4] and ceftazidime-imipenem antagonism test)[5] and test for presence of effl ux pump were performed.[6] Multiplex polymerase chain reaction (PCR) for CTX-M gene 1, 2, 8, 9 and 25[7] and blaIMP-1, blaIMP-2, blaVIM-1 and blaVIM-2 of carbapenemases genes were done.[6]

Predictors of Poor Outcome in Neonates with Pyogenic Meningitis in a Level-Three Neonatal Intensive Care Unit of Developing Country

Background The mortality of neonatal pyogenic meningitis is reduced to 10-15%, but morbidity is unchanged. Methods Primary objective is to determine the outcome, i.e. death or abnormal neurological examination (NE) at discharge and abnormal developmental quotient (DQ) at 3 months. Secondary objective is to find predictors of poor outcome. Results In all, 89 neonates enrolled, 10 expired and 24 neonates had abnormal NE at discharge. A total of 59 neonates came for follow up, 13 had DQ < 70. Prolonged shock (odds ratio, OR: 8.28; p = 0.001), coma (OR: 4.3; p = 0.001), seizures (OR: 14; p = 0.012), mechanical ventilation (OR: 18.55; p = 0.00), orogastric feeding (OR: 2.78; p = 0.042) and electroencephalography (EEG; OR: 9.6; p = 0.00) predicted poor short-term outcome. Abnormal NE at discharge (OR: 15.6; p = 0.001), EEG (OR = 10.60; p = 0.00) and brainstem-evoked reflex audiometry (OR = 37.20, p = 0.00) predicted a low DQ at 3 months. Mortality and morbidity of neonates with Pyogenic Meningitis (PM) were similar to that in developed countries. Outcome depended on severity of the disease and NE at discharge.

Chryseobacterium indologenes Associated Pneumonia in Two Neonates.

Chryseobacterium species are widely distributed in nature and can rarely cause human infection. Few cases reported in hospitalized patients are in immunocompromised hosts with indwelling devices and associated comorbidities. Chryseobacterium species are usually multidrug resistant. We describe 2 cases of Chryseobacterium indologenes-associated pneumonia in neonates and review the published infant cases.
