Outcomes of double-incision posterior knee release for severe knee flexion contracture.

Many surgical solutions for knee flexiondeformity in the pediatric population alter the anatomical bony alignment in the distal femur. Posterior knee capsule release has been presented as an alternative surgical procedurethat maintains the anatomical shape of relevant bones while solving the issue of knee flexion contracture. The aim of this study is to assess the results of a double-incision posteriorknee capsulotomy release performed on pediatric patients with neuromuscular or congenital severe knee flexion deformity.

Hemangioma-related gene polymorphisms in the pathogenesis of intraventricular hemorrhage in preterm infants.

Purpose: The aim of this study was to evaluate the possible relationship between four single nucleotide polymorphisms of hemangioma-linked genes encoding for anthrax toxin receptor 1 (ANTXR1 G976A), R kinase insert domain receptor (KDR T1444C), adrenoceptor beta 2 (ADRB C79CG), and insulin-like growth factor 1 receptor (IGF-1R G3174A) and the occurrence of IVH in a population of preterm infants.

Methods: The study includes a population of 105 infants born from 24 + 0 to 32 + 0 weeks of gestation and hospitalized at the Department of Neonatology (III level hospital) of Poznan University of Medical Science. Intraventricular hemorrhage was diagnosed with the use of cranial ultrasound.

Catheter-related bloodstream infections in infants hospitalized in neonatal intensive care units: a single center study.

Sepsis in neonates carries a high morbidity and mortality rate and is among the most feared complications in the neonatal intensive care unit (NICU). Catheter-related bloodstream infections (CRBSI) are a common etiology of late-onset sepsis. The aim of this study was to compare risk factors and characteristics between patients according to the type of catheter that was utilized and according to birth weight classification.

Polymorphisms of fibronectin-1 (rs3796123; rs1968510; rs10202709; rs6725958; and rs35343655) are not associated with bronchopulmonary dysplasia in preterm infants.

Bronchopulmonary dysplasia (BPD) is a chronic lung disease that mainly affects premature newborns. Many different factors, increasingly genetic, are involved in the pathogenesis of BPD. The aim of the study is to investigate the possible influence of fibronectin SNP on the occurrence of BPD.

Contracting COVID-19 in the first and second trimester of pregnancy: what we know - a concise qualitative systematic review.

Introduction: Recent medical literature has drawn attention to the possible influence of COVID-19 on the course of pregnancies. As the coherence of results seems to vary, especially in relation to first and second trimester pregnancies, a concise qualitative systematic review can shed light on the most recent data.

Material And Methods: A structured systematic search was performed to collect all COVID-19 pregnancy-related articles published between January 1 and September 16, 2020.

Hearing Impairment in Infants with Hypoxic Ischemic Encephalopathy Treated with Hypothermia.

Therapeutic hypothermia acts as the standard of care for infants with moderate to severe hypoxic ischemic encephalopathy (HIE). A proportion of neonates who undergo hypothermia due to HIE have shown to develop various degrees of hearing impairment. Analyzing and identifying infants at high risk of developing hearing difficulties is fundamental for early intervention of such auditory complications.

Single nucleotide vitamin D receptor polymorphisms (FokI, BsmI, ApaI, and TaqI) in the pathogenesis of prematurity complications.

The vitamin D receptor (VDR), coded by the VDR gene, plays a pivotal role in executing cellular functions when bound by the active form of vitamin D. Gene polymorphisms in this receptor have been increasingly associated with a heightened state of vulnerability to certain diseases. However, limited data is available concerning the role of VDR gene polymorphisms in preterm infant complications.

Clinical Characteristics and Survival Analysis in a Small Sample of Older COVID-19 Patients with Defined 60-Day Outcome.

The older population is one of the most vulnerable to experience adverse outcomes of COVID-19. Exploring different clinical features that may act as detrimental to this population's survival is pivotal for recognizing the highest risk individuals for poor outcome. We thus aimed to characterize the clinical differences between 60-day survivors and non-survivors, as well as analyze variables influencing survival in the first older adults hospitalized in Poznan, Poland, with COVID-19.

Organ Complications of Infants with Hypoxic Ischemic Encephalopathy Before Therapeutic Hypothermia.

Hypoxic ischemic encephalopathy (HIE) is a serious neurological complication that may develop in asphyxiated infants. Severity of encephalopathy may vary, and concurrent multiorgan dysfunctions are commonly observed. Analyzing the incidence of such complications according to severity of HIE, and how they correlate with each other, may shape clinical judgment and allow for early intervention.

COVID 19 - Clinical Picture in the Elderly Population: A Qualitative Systematic Review.

The SARS-CoV-2 tendency to affect the older individuals more severely, raises the need for a concise summary isolating this age population. Analysis of clinical features in light of most recently published data allows for improved understanding, and better clinical judgement. A thorough search was performed to collect all articles published from 1st of January to 1st of June 2020, using the keywords and followed by the generic terms , or .

Role of Fibronectin-1 polymorphism genes with the pathogenesis of intraventricular hemorrhage in preterm infants.

Background/introduction: Intraventricular hemorrhage (IVH) is a dangerous complication facing a significant proportion of preterm infants. It is multifactorial in nature, and an observed fibronectin deficiency in the germinal matrix basal lamina is among the most prominent factors that influence such rupture. Better understanding of the FN1 gene polymorphisms and their role in IVH may further clarify the presence of a genetic susceptibility of certain babies to this complication.
