RESUMEN

Despite evidence of short- and long-term benefits of developmental care, several studies have documented nurses' lack of knowledge and skills related to developmental care concepts. This study aims to enhance neonatal nurses' abilities to acquire care practices (knowledge and skills) regarding Developmental Supportive Care (DSC). A nonrandomized before and after intervention design was adopted to improve the knowledge and skills of staff nurses in DSC practices for preterm infants in Level III B NICU. The study included 50 level III B NICU nurses (25 in interventional group, 25 in control group) located within a tertiary care hospital in India. A significant increase in the mean knowledge score was seen among participants in the intervention group (pre-test: 16.6 ±â€¯3.1, post-test: 29.9 ±â€¯4.1, p = 0.01) but not in the control group (pre: 16.4 ±â€¯2.2, post: 18.6 ±â€¯3.6, p = 0.98). The improvement in the skills of providing DSC among neonatal nurses was also higher in the intervention group (106.4 ±â€¯7.4) relative to the control group (65.8 ±â€¯3.6), p < 0.01, at 0.05 level of significance. The Developmental Supportive Care Program (DSCP) had a significant impact in improving the knowledge and skills of nurses in providing care and preventing complications in preterm infants.

RESUMEN

OBJECTIVE: Methylxanthines are the most commonly prescribed drug in neonatal setups. However, Clinicians show indecision in choosing the right agent for Apnea of Prematurity in most of the developing countries. Present study aimed to compare rate of mortality and survival with normal neurodevelopment outcome at 18 to 24 months of corrected age, between Caffeine- and Aminophylline-treated infants for apnea of prematurity. METHODS: 240 infants were randomly allocated to caffeine and aminophylline for apnea of prematurity during February 2012 to January 2015. Long-term neurodevelopmental assessment was done only from children who had attained corrected age of 18 to 24 months during April 2014 to February 2016. Cognitive, language and motor deficits were assessed by Bayley Scale of infant and toddler development (BSID - III). Postnatal characteristics such as hearing and visual impairments during NICU stay were noted and same were followed up. RESULTS: Infants allocated to caffeine group showed 83% less risk of getting cognitive impairment (RR 0.16; CI 95% range 0.02 to 1.36), 50% less risk of developing motor deficits (RR 0.50; CI 95% range 0.12 to 1.95) and 24% less risk of developing language problems (RR 0.76; CI 95% range 0.36 to 1.58). However in all the neurodevelopment domains the difference between groups was not statistically significant. Risk of mortality in caffeine group was 9% less over aminophylline group which was statistically non-significant (RR - 0.92; CI 95% range - 0.45 to 1.84; p = 0.81). Physical growth parameters were found to be similar in both the groups. Risk of developing visual abnormality and hearing impairments was also statistically non-significant between the groups. CONCLUSION: Caffeine and aminophylline showed similar effects in reducing the rate of mortality and improving the survival without neurodevelopment delays; though the clinical significance of caffeine over aminophylline cannot be undermined.

RESUMEN

The pathogenicity of the opportunistic human fungal pathogen Candida albicans depends on its ability to escape destruction by the host immune system. Using mutant strains that are defective in cell surface glycosylation, cell wall protein synthesis, and yeast-hypha morphogenesis, we have investigated three important aspects of C. albicans innate immune interactions: phagocytosis by primary macrophages and macrophage cell lines, hyphal formation within macrophage phagosomes, and the ability to escape from and kill macrophages. We show that cell wall glycosylation is critically important for the recognition and ingestion of C. albicans by macrophages. Phagocytosis was significantly reduced for mutants deficient in phosphomannan biosynthesis (mmn4Delta, pmr1Delta, and mnt3 mnt5Delta), whereas O- and N-linked mannan defects (mnt1Delta mnt2Delta and mns1Delta) were associated with increased ingestion, compared to the parent wild-type strains and genetically complemented controls. In contrast, macrophage uptake of mutants deficient in cell wall proteins such as adhesins (ece1Delta, hwp1Delta, and als3Delta) and yeast-locked mutants (clb2Delta, hgc1Delta, cph1Delta, efg1Delta, and efg1Delta cph1Delta), was similar to that observed for wild-type C. albicans. Killing of macrophages was abrogated in hypha-deficient strains, significantly reduced in all glycosylation mutants, and comparable to wild type in cell wall protein mutants. The diminished ability of glycosylation mutants to kill macrophages was not a consequence of impaired hyphal formation within macrophage phagosomes. Therefore, cell wall composition and the ability to undergo yeast-hypha morphogenesis are critical determinants of the macrophage's ability to ingest and process C. albicans.
