Identification of Novel Biomarkers in Late Preterm Neonates with Respiratory Distress Syndrome (RDS) Using Urinary Metabolomic Analysis.

Urine metabolomics is gaining traction as a means of identifying metabolic signatures associated with health and disease states. Thirty-one (31) late preterm (LP) neonates admitted to the neonatal intensive care unit (NICU) and 23 age-matched healthy LPs admitted to the maternity ward of a tertiary hospital were included in the study. Proton nuclear magnetic resonance (H NMR) spectroscopy was employed for urine metabolomic analysis on the 1st and 3rd days of life of the neonates.

Objectives: The aim of this study was to investigate the effect of the application of orthodontic tooth forces on the alveolar bone distal to the loaded teeth, in ovariectomized female rats.

Methods: Twenty-four eight-month-old Wistar rats were divided into one group ovariectomized at the age of six months and one control. An orthodontic appliance delivering a mesial traction force of 60 gr* was placed on the right maxillary 1 molar of all animals for 14 days.

Intraoral Scanners in Orthodontics: A Critical Review.

Background: The use of digital technology has exponentially increased over recent years. Intraoral scanners, especially, have gained traction within orthodontics. The objective of the present review is to investigate the available evidence to create an up-to-date presentation of various clinical aspects of intraoral scanners in orthodontics.

Mid-term follow up effectiveness of facemask treatment in class III malocclusion: A systematic review.

Objective: This systematic review aims to investigate and summarize the mid-term effects and stability of the treatment with facemask appliance.

Methods: Search without restrictions in five databases (Pubmed, Medline, Embase, Scopus, Cochrane Central Register of Controlled Trials) since inception and hand searching until March 2021 was conducted. Detailed search strategies were based on the PubMed strategy and adapted accordingly.

Patient-reported experiences and preferences with intraoral scanners: a systematic review.

Background: Intraoral scanners have become an increasingly popular alternative to conventional impression methods. Although their accuracy and validity have been examined thoroughly, patient-reported information including experiences, preferences, and satisfaction has not yet been investigated in a systematic way.

Objective: The objective of this systematic review is to investigate the available data and appraise the evidence on patient-reported experiences and preferences following impression taking with intraoral scanners.

Extensively-drug resistant bacteremia in neonates: effective treatment with the combination of colistin and ampicillin/sulbactam.

has evolved as a major pathogen of outbreaks in the healthcare setting with increased morbidity and mortality. In neonates, treatment can be quite challenging due to the resistance profile of as well as limited data on pharmakokinetics and pharmakodynamics of antibiotics in this age group. We present an outbreak of eight cases of extensively-drug resistant (XDR) bacteremias successfully managed with the combination of colistin with high dose ampicillin/sulbactam.

TIV Vaccination Modulates Host Responses to Influenza Virus Infection that Correlate with Protection against Bacterial Superinfection.

Background: Influenza virus infection predisposes to secondary bacterial pneumonia. Currently licensed influenza vaccines aim at the induction of neutralizing antibodies and are less effective if the induction of neutralizing antibodies is low and/or the influenza virus changes its antigenic surface. We investigated the effect of suboptimal vaccination on the outcome of post-influenza bacterial superinfection.

Intranodal administration of mRNA encoding nucleoprotein provides cross-strain immunity against influenza in mice.

Background: Current human influenza vaccines lack the adaptability to match the mutational rate of the virus and therefore require annual revisions. Because of extensive manufacturing times and the possibility that antigenic alterations occur during viral vaccine strain production, an inherent risk exists for antigenic mismatch between the new influenza vaccine and circulating viruses. Targeting more conserved antigens such as nucleoprotein (NP) could provide a more sustainable vaccination strategy by inducing long term and heterosubtypic protection against influenza.

Broadened immunity against influenza by vaccination with computationally designed influenza virus N1 neuraminidase constructs.

Split inactivated influenza vaccines remain one of the primary preventative strategies against severe influenza disease in the population. However, current vaccines are only effective against a limited number of matched strains. The need for broadly protective vaccines is acute due to the high mutational rate of influenza viruses and multiple strain variants in circulation at any one time.

Neutralization of Junín virus by single domain antibodies targeted against the nucleoprotein.

The syndrome viral haemorrhagic fever (VHF) designates a broad range of diseases that are caused by different viruses including members of the family Arenaviridae. Prophylaxis for Argentine Haemorrhagic Fever (AHF), caused by the arenavirus Junín (JUNV), has been achieved by the use of a live attenuated vaccine, named Candid#1. The standard treatment of AHF is transfusion of convalescent human plasma.

Influenza vaccines to control influenza-associated bacterial infection: where do we stand?

Influenza A virus is a pathogen that is feared for its capacity to cause pandemics. In this review, we illustrate the clinical evidence which support the theory that bacterial co-infection is a considerable risk factor for exacerbated disease during pandemic and seasonal influenza, including infection with influenza B viruses. We provide an overview of the multiple and diverse mechanisms that help explain how influenza creates an opportunity for replication of secondary bacterial infections.

Assessment and Analysis of Workplace Violence in a Greek Tertiary Hospital.

This study sought to assess workplace violence in a Greek tertiary hospital for the first time. The authors conducted a descriptive study with 175 participants and examined the characteristics of violent episodes, the responses of victims and the administration, and the perception of workplace safety in addition to the implications of these incidents. The vast majority of employees (83.

rhIL-12 as adjuvant augments lung cell cytokine responses to pneumococcal whole cell antigen.

Conjugate pneumococcal vaccines offer suboptimal protection against mucosal infections and are restricted in serotype and geographical coverage. New protein-based vaccines using conserved pneumococcal antigens and better mucosal adjuvant technology are urgently needed. Interleukin-12 (IL-12) has shown efficacy as a pneumococcal protein vaccine adjuvant in murine models of pneumococcal infection.

Factors affecting the decision of cancer patients to be cared for at home or in hospital.

Community health care and, more specifically, home health care are major developments over recent years. In many European countries there has been serious debate on the necessity of home care, the importance of this type of health care for the patient and family, and those factors influencing patient choice with regard to health care at home or in hospital. This question of choice between home and hospital care forms the basis of this piece of research, the aim of which is to examine the biosocial factors that influence the decision of cancer patients in Greece to choose health care at home or in hospital.
