The neutrophil-to-lymphocyte ratio (NLR) is a simple, cost-effective index of inflammation that can be measured by peripheral blood count. This study aimed to reveal that a high NLR value could be a prognostic marker for mortality risk in preterm babies born with IVH. ⋯ This was the first study to examine the relationship between the NLR and mortality in preterm babies with IVH. This study showed that a high NLR was strongly associated with mortality in premature infants with low APGAR scores and having IVH.

To determine and compare pelvic and lumbosacral reference parameters with computed tomography in patients with low back pain (LBP) and a control group of asymptomatic patients to provide quantification data and morphological correlations for L5S1 transforaminal endoscopic approach (L5S1TEA). ⋯ Our results set preliminary reference values for L5S1TEA surgical planning. Besides higher ICPi, there were no differences between groups in measured parameters. Traditional IC height (ICPh) does not correspond to the point of intersection of the approach and is significantly higher than ICPi. ICi correlated to higher facet angle values, ICPh and ICPi grades, and lower ΔICi-SP. Potential conflict with the ilium is increased in the male population. IC is not impeditive of L5S1TEA in most cases.

Lumbosacral pseudoarthrosis is a common complication following adult spine deformity (ASD) surgery. This study assessed the reoperation rate for L5-S1 pseudoarthrosis in the ASD population. Compared with transforaminal lumbar interbody fusions (TLIFs), we hypothesized that anterior lumbar interbody fusion (ALIF) would result in lower rates of L5-S1 pseudarthrosis. ⋯ No difference in reoperation risk for L5-S1 pseudarthrosis was observed based on the method of IF. rhBMP-2 was noted as a significant predictor.

To assess the status of brain tumor programs in Asia and Africa and propose comprehensive evidence-based short- and long-term measures for improving the existing systems. ⋯ There is an urgent need to improve and develop existing and nonexistent neuro-oncology infrastructure, personnel, and logistics in countries across the continents, especially for the countries with no neurosurgeons.

Maximal surgical resection remains the treatment of choice for grade II meningiomas, and for some authors it is sufficient to guarantee a long indolent course even without postsurgical radiotherapy (RT), but there is no consensus on the use of RT in this patient population. ⋯ Recurrence is more frequent for grade II meningiomas, even though there are no significant differences in terms of complications and functional outcome. Radiotherapy in grade II meningiomas does indeed lead to better control of recurrence but leads to an increased risk of seizures and reduced performance status.
