The importance of assessing general motor activity in premature infants for predicting neurological outcomes.

INTRODUCTION: Conventional methods of neurological assessment of infants can detect nervous system damage, but also have a weakness, i.e., the inability to make predictions for neurological deficits. Prechtl's general movement assessment is a diagnostic tool for the functional assessment of young nervous system. The aim of the study was to assess the quality of spontaneous motor activity in preterm newborns as well as to determine the neurological outcome at the age of 24 months. After that, the predictive value of spontaneous motor activity for neuro-developmental outcome at the age of 24 months was determined. MATERIAL AND METHODS: The study included 160 pre-terms children, and designed as a prospective clinical study. Observation of spontaneous motor activity was performed according to the principles of Prechtl's method. RESULTS: Spontaneous motor activity was observed in three periods for each newborn: within 5 days of birth, in the period of 44-46 gestation weeks, and in the period of 50-54 gestation weeks of post-menstrual age. Neurological outcome was assessed at the age of 24 months, and was classified as: normal finding, minimal neurological dysfunction, and cerebral palsy. All preterms, who presented normal patterns of spontaneous movements in neonatal and infant periods had a normal neurological functional outcomes at the age of 24 months. Newborns with pathological patterns of movement (cramped synchronized and absence of fidgety movements) in neonate and infant periods in the final outcomes had minimal neurological dysfunction or cerebral palsy. CONCLUSIONS: Assessment of general movement in preterms is a valuable method in prediction of dysfunctions in later neurological development. Early detection of symptoms of minimal neurological deficit and cerebral palsy is of crucial importance since it enables timely inclusion of children into neuro-developmental treatment.

Potential role of IFN-γ and IL-5 in sepsis prediction of preterm neonates.

Not fully maturated immune system in preterm neonates may contribute to the increased susceptibility to infection. The levels of some cytokines can be useful in the prediction and diagnosis of sepsis in premature neonates. In the present study, we evaluated the potential predictive role of IFN-γ and IL-5 in cord and venous blood, together with the determination of C-reactive protein and procalcitonin (PCT) for sepsis development in premature neonates. A total of 80 participants were included. The laboratory results and clinical histories showed that 21 participants had sepsis. Early onset sepsis was detected in 3 patients while late onset sepsis was observed in 18 participants. The venous plasma levels of IFN-γ and PCT was markedly increased in sepsis groups when compared to the participants without sepsis. On the other hand, levels of IL-5 did not significantly change in the evaluated groups of sepsis and in the control group of participants. Simultaneously, plasma venous levels were not altered in any of the evaluated groups. Obtained findings suggest that venous plasma levels of IFN-γ, rather than levels of IFN-γ in cord blood plasma, and PCT may have predictive potential for sepsis development in preterm neonates. Further studies are necessary to get more comprehension of the complex function of cytokines for sepsis development in preterm neonates.

The effect of curcumin and PI3K/Akt inhibitor on monosodium glutamate-induced rat thymocytes toxicity.

Monosodium glutamate (MSG), the sodium salt of glutamic acid, is widely used in modern nutrition as flavor enhancer. However, it has been shown that curcumin has ability to induce apoptosis in the cells of the immune system. In the present study, we evaluate the potential protective effects of curcumin in MSG-induced apoptosis and signaling pathway which may be involved. Rat thymocytes were treated with increased (1, 10, 50 mM) MSG concentrations and/or curcumin (3 µM). Cell apoptosis rate, reactive oxygen species (ROS) production, mitochondrial membrane potential (MMP), Bcl-2, Bax protein expression and caspase-3 activity were determined after 24 hours of incubation. Treatment with MSG resulted with increased apoptosis, ROS production and caspase-3 activity, followed with decreased MMP and Bcl-2/Bax protein ratio. Inhibition of caspase-3 and caspase-9 activity reduced cell apoptosis, indicating the involvement of mitochondrial apoptotic pathway. Co-treatment with curcumin markedly reduced apoptosis and ROS production, together with increased MMP and Bcl2/Bax protein ratio. Inhibition of PI3K/Akt signaling pathway abolished protective effect of curcumin in MSG-induced toxicity in rat thymocytes. Obtained findings suggest that curcumin may attenuate the MSG-induced apoptosis through PI3K/Akt signaling pathway which could be useful in preventing the potential deficiencies in T cell-mediated immunity.

Comparison of weight and length at birth of non-Roma and Roma newborn in Serbia.

OBJECTIVES: Roma infants tend to be smaller and are diagnosed as SGA more often than non-Roma infants, suggesting that specific anthropometric norms for these infants may be useful. We aimed to construct population-based centile, gender-specific charts for birth weight and length for singleton Roma infants born from 35 to 42 weeks of gestation and to compare it with anthropometric data of non-Roma infants. METHODS: We analyzed data on 27,602 non-Roma (53 % males) and 2235 Roma (51 % males) singleton live infants delivered from 2006 to 2012 in South East Serbia. The LMS method was used to estimate the birth weight and length centiles. RESULTS: Roma infants were up to 12 % lighter and up to 4 % shorter than non-Roma infants. Estimated centile charts for Roma males and females were constructed showing the 3rd, 10th, 25th, 50th, 75th, 90th and 97th centiles. CONCLUSIONS: We created the separate centile charts for Roma ethnic group. The sample size was sufficient to demonstrate differences in mean birth weights and lengths of at term infants born during the study period.

Neonatal tetanus--report of a case.

Neonatal tetanus is a severe, often fatal disease caused by the toxin Clostridium tetani. Neonatal tetanus is a generalized tetanus, which occurs in a neonate between 3-28 days of life. The findings indicated that tetanus in a newborn of an unvaccinated mother occurred after the application of non-sterile clay to the umbilical cord. This case was a seven-day-old male baby with progressive difficulty in feeding, trismus, hypertonicity, opisthotonos, and heart murmur. The patient was afebrile and eupneic, and had a history of non-sterile home delivery. In the past, the area of Bujanovac, Medvedja and Presevo had been exposed to mass immigration (especially due to the war in the territory of former Yugoslavia), which caused a serious problem for general practitioners, who had to be vigilant and ensure that all patients registered in their practice were fully immunized. This case has provided a clear indication of the necessity for strategies of both vaccination and ensuring hygienic conditions throughout pregnancy and delivery to prevent neonatal tetanus.
