Testing the reported long-term advantages of protein-fortified human milk in very low birth weight neonates.

Preterm infants are at-risk for extrauterine growth restriction and downward percentile-crossing between birth and discharge. Increased energy and protein intake through fortification of human milk during the first weeks of life has been associated with improved short-term growth and better developmental outcomes. The aim of this study was to evaluate whether these benefits persist up to children school age.

A descriptive analysis of COVID-19 associated mortality in Parma Province: concordance between official national mortality register provided by ISTAT (National Institute of Statistics) and local ADS (Automated Data System) real-time surveillance flow.

Background And Aim: The Public Health Department of the Parma Local Health Authority (AUSL) has implemented a computerized system called ADS (Automated Data System) to collect data on COVID-19 cases and related deaths, as required by the Emilia-Romagna Region and the Italian Ministry of Health, to improve the daily flow of real-time information. However, official mortality data for all causes was collected even from the National Institute of Statistics (ISTAT) through death forms that were completed by certifying doctors in each municipality. This analysis aims to verify the agreement between the data collected by ISTAT and the data collected by ADS.

Clinical approach to prostatic diseases in the dog.

In small animal practice, prostatic diseases are increasingly encountered. All dogs may experience prostatic disease, but particular care should be addressed to breeding dogs, in which prostatic affection may lead to decrease in semen quality and fertility. The most common prostatic disease is the benign prostatic hyperplasia (BPH) followed by prostatitis, prostatic neoplasia and prostate squamous metaplasia.

Strategies of Increased Protein Intake in ELBW Infants Fed by Human Milk Lead to Long Term Benefits.

The aim of this observational study was to evaluate the effects of two different protein intake regimes on feeding tolerance, in-hospital growth, anthropometric data and psychomotor outcome up to 24 months corrected age (CA) in extremely low birth-weight (ELBW; birth weight <1000 g) infants. During the period 2008-2013, 52 ELBW infants admitted at birth to two Neonatal Intensive Care Units of Emilia Romagna (Italy) were fed according to different protocols of protein fortification of human milk: an estimated protein intakes at maximum fortification levels of 3.5 gr/kg/day in the Standard Nutrition Population-SNP group ( = 26) and 4.

Sex-Specific Transcriptome Differences in Substantia Nigra Tissue: A Meta-Analysis of Parkinson's Disease Data.

Parkinson's disease (PD) is one of the most common progressive neurodegenerative diseases. Clinical and epidemiological studies indicate that sex differences, as well as genetic components and ageing, can influence the prevalence, age at onset and symptomatology of PD. This study undertook a systematic meta-analysis of substantia nigra microarray data using the Transcriptome Mapper (TRAM) software to integrate and normalize a total of 10 suitable datasets from multiple sources.

Meta-Analysis of Parkinson's Disease Transcriptome Data Using TRAM Software: Whole Substantia Nigra Tissue and Single Dopamine Neuron Differential Gene Expression.

The understanding of the genetic basis of the Parkinson's disease (PD) and the correlation between genotype and phenotype has revolutionized our knowledge about the pathogenetic mechanisms of neurodegeneration, opening up exciting new therapeutic and neuroprotective perspectives. Genomic knowledge of PD is still in its early stages and can provide a good start for studies of the molecular mechanisms that underlie the gene expression variations and the epigenetic mechanisms that may contribute to the complex and characteristic phenotype of PD. In this study we used the software TRAM (Transcriptome Mapper) to analyse publicly available microarray data of a total of 151 PD patients and 130 healthy controls substantia nigra (SN) samples, to identify chromosomal segments and gene loci differential expression.

Does the Use of Pacifier Affect Gastro-Esophageal Reflux in Preterm Infants?

Unlabelled: This crossover study showed that non-nutritive sucking, provided with a pacifier in 30 preterm infants, had no effect on acid and nonacid gastro-esophageal reflux evaluated by esophageal pH-impedance, and thus may be reasonably used in preterm neonates with symptoms of gastro-esophageal reflux.

Trial Registration: ClinicalTrials.gov: NCT02023216.

Small airway dysfunction is associated to excessive bronchoconstriction in asthmatic patients.

Background: We investigated whether a relationship between small airways dysfunction and bronchial hyperresponsiveness (BHR), expressed both in terms of ease of airway narrowing and of excessive bronchoconstriction, could be demonstrated in asthma.

Methods: 63 (36 F; mean age 42 yr ± 14) stable, mild-to-moderate asthmatic patients (FEV1 92% pred ±14; FEV1/FVC 75% ± 8) underwent the methacholine challenge test (MCT). The degree of BHR was expressed as PD20 (in μg) and as ∆FVC%.

Characterization of human gene locus CYYR1: a complex multi-transcript system.

Cysteine/tyrosine-rich 1 (CYYR1) is a gene we previously identified on human chromosome 21 starting from an in-depth bioinformatics analysis of chromosome 21 segment 40/105 (21q21.3), where no coding region had previously been predicted. CYYR1 was initially characterized as a four-exon gene, whose brain-derived cDNA sequencing predicts a 154-amino acid product.

Extensively hydrolyzed protein formula reduces acid gastro-esophageal reflux in symptomatic preterm infants.

Background: Gastro-esophageal reflux (GER) is diagnosed frequently in preterm infants. Pharmacological treatment of GER has some potential side effects. Conservative treatment of GER should be the first-line approach and should include body positioning and diet modifications.

Where Birt-Hogg-Dubé meets Cowden syndrome: mirrored genetic defects in two cases of syndromic oncocytic tumours.

Birt-Hogg-Dubè (BHD) is an autosomal dominant syndrome characterised by skin fibrofolliculomas, lung cysts, spontaneous pneumothorax and renal cancer. The association of benign cutaneous lesions and increased cancer risk is also a feature of Cowden Syndrome (CS), an autosomal dominant disease caused by PTEN mutations. BHD and CS patients may develop oncocytomas, rare neoplasias that are phenotypically characterised by a prominent mitochondrial hyperplasia.

A thickened formula does not reduce apneas related to gastroesophageal reflux in preterm infants.

Background: Apnea of prematurity (AOP) occurs frequently in preterm infants and a variable proportion of AOP can be induced by gastroesophageal reflux (GER). Conservative treatment, including dietary modifications, should be the first-line approach for both GER and GER-related apneas in this population.

Objectives: To evaluate the efficacy of a starch-thickened preterm formula (PF) in reducing the frequency of apneas related to GER.

Lack of efficacy of a starch-thickened preterm formula on gastro-oesophageal reflux in preterm infants: a pilot study.

Background: Gastro-oesophageal reflux (GOR) is common in preterm infants; conservative interventions (i.e. dietary changes) should represent the first-line approach.

Sodium Alginate (Gaviscon®) does not reduce apnoeas related to gastro-oesophageal reflux in preterm infants.

Background: Apnoea of prematurity (AOP) frequently recurs in preterm infants. We have previously shown that a significant but variable proportion of AOP is induced by gastro-oesophageal reflux (GOR).

Aim: The aim of this study is to evaluate the efficacy of sodium alginate in reducing the frequency of GOR-related AOP.

Standard fortification of preterm human milk fails to meet recommended protein intake: Bedside evaluation by Near-Infrared-Reflectance-Analysis.

Background: Protein content of preterm human milk (HM) is relatively low and extremely variable among mothers: thus, recommended protein intake is rarely met.

Objectives: To evaluate in a NICU setting if HM protein content after standard fortification meets the recommended intake, and also to check the effect of fortification on the osmolality of HM, as an index of feeding intolerance.

Methods: Protein content of 34 preterm HM samples was evaluated by a bedside technique (Near-Infrared-Reflectance-Analysis - NIRA); osmolality was also checked.

The RET51/FKBP52 complex and its involvement in Parkinson disease.

The tyrosine kinase receptor RET51 is expressed in distinct families of neurons where it promotes different functions. FKBP52 is an immunophilin with neuroprotective effects on different kinds of neurons. In this paper, we demonstrate that RET51 activation by both glial cell line-derived neurotrophic factor (GDNF) and NGF triggers the formation of RET51/FKBP52 complex.

Protein content and fortification of human milk influence gastroesophageal reflux in preterm infants.

Objectives: : Preterm human milk (HM) may provide insufficient energy and nutrients and thus may need to be fortified. Our aim was to determine whether fat content, protein content, and osmolality of HM before and after fortification may affect gastroesophageal reflux (GER) in symptomatic preterm infants.

Methods: : Gastroesophageal reflux was evaluated in 17 symptomatic preterm newborns fed naïve and fortified HM by combined pH/intraluminal-impedance monitoring (pH-MII).

An inherited mitochondrial DNA disruptive mutation shifts to homoplasmy in oncocytic tumor cells.

A disruptive frameshift mtDNA mutation affecting the ND5 subunit of complex I is present in homoplasmy in a nasopharyngeal oncocytic tumor and inherited as a heteroplasmic germline mutation recurring in two of the patient's siblings. Homoplasmic ND5 mutation in the tumor correlates with lack of the ND6 subunit, suggesting complex I disassembly. A few oncocytic areas, expressing ND6 and heteroplasmic for the ND5 mutation, harbor a de novo homoplasmic ND1 mutation.

Respiratory complex I dysfunction due to mitochondrial DNA mutations shifts the voltage threshold for opening of the permeability transition pore toward resting levels.

We have studied mitochondrial bioenergetics in HL180 cells (a cybrid line harboring the T14484C/ND6 and G14279A/ND6 mtDNA mutations of Leber hereditary optic neuropathy, leading to an approximately 50% decrease of ATP synthesis) and XTC.UC1 cells (derived from a thyroid oncocytoma bearing a disruptive frameshift mutation in MT-ND1, which impairs complex I assembly). The addition of rotenone to HL180 cells and of antimycin A to XTC.
