Closed-Loop Automatic Oxygen Control (CLAC) in Preterm Infants: A Randomized Controlled Trial

2014

BACKGROUND AND OBJECTIVE: In preterm infants receiving supplemental oxygen, routine manual control (RMC) of the fraction of inspired oxygen (FIO2) is often difficult and time consuming. We developed a system for closed-loop automatic control (CLAC) of the FIO2 and demonstrated its short-term safety and efficacy in a single-center study. The objective of this study was to test the hypothesis that this system is more effective than RMC alone in maintaining arterial oxygen saturation within target levels when evaluated over 24 hours under routine conditions and with different target levels. METHODS: We performed a multicenter, randomized controlled, crossover clinical trial in 34 preterm infa…

Vadības modeļa "Atbalsts pozitīvai uzvedībai" ieviešana Ozolnieku vidusskolā

2017

Jau ilgāku laiku pasaulē un vairākus gadus Latvijas sabiedrībā visos līmeņos tiek diskutēts jautājums par skolēnu uzvedību - vardarbību, agresiju skolā, par to kā uzturēt klasē kārtību, lai skolēni skolā varētu mācīties un skolotāji strādāt. Pasaulē veiktajos pētījumos vairāku gadu desmitu laikā dominē viedoklis, ka kārtībai klasē un skolēnu sasniegumiem ir cieša saistība – jo klasē ir pozitīvāka vide, kas nodrošina kārtību, jo vairāk skolēns iesaistās mācībās un viņa sasniegumi ir augstāki. Par netraucētu mācību vidi Latvijā runā arī Izglītības likums, kurā noteikts, ka izglītības iestādē un tās organizētajos pasākumos jābūt dzīvībai un veselībai drošiem apstākļiem un nodrošinātai atbilsto…

Detecting multiple copies in tampered images

2010

Copy-move forgeries are parts of the image that are duplicated elsewhere into the same image, often after being modified by geometrical transformations. In this paper we present a method to detect these image alterations, using a SIFT-based approach. First we describe a state of the art SIFT-point matching method, which inspired our algorithm, then we compare it with our SIFT-based approach, which consists of three parts: keypoint clustering, cluster matching, and texture analysis. The goal is to find copies of the same object, i.e. clusters of points, rather than points that match. Cluster matching proves to give better results than single point matching, since it returns a complete and co…

Modelling agricultural risk in a large scale positive mathematical programming model

2020

International audience; Mathematical programming has been extensively used to account for risk in farmers' decision making. The recent development of the positive mathematical programming (PMP) has renewed the need to incorporate risk in a more robust and flexible way. Most of the existing PMP-risk models have been tested at farm-type level and for a very limited sample of farms. This paper presents and tests a novel methodology for modelling risk at individual farm level in a large scale model, called individual farm model for common agricultural policy analysis (IFM-CAP). Results show a clear trade-off between including and excluding the risk specification. Albeit both alternatives provid…

Perioperative Adverse Events in Obstructive Sleep Apnea and Use of Noninvasive Mechanical Ventilation: Key Topics and Clinical Implications

2016

Obstructive sleep apnea (OSA) is a common public health care problem and, yet, the perioperative management of OSA remains inadequate. Patients affected by this condition are prone to early postoperative complications, in part due to the negative effects of sedative, analgesic, and anesthetic agents on pharyngeal tone and arousal responses to hypoxia, hypercapnia, and obstruction. The use of opioids may also contribute to late adverse events, mainly by suppressing the rapid eye movement phase of sleep. As a result, preoperative screening of patients at high risk of OSA, as well as the implementation of a perioperative strategy to reduce the risk of complications, should lead to early periop…

A narrative review of positive psychology interventions for women during the perinatal period

2019

Recent studies suggest that positive perinatal maternal mood can buffer the effects of negative feelings and promote women and infant well-being. Evidence from Positive Psychology has shown that Positive Psychology Interventions (PPIs) can enhance well-being and/or reduce negative symptoms. The objective of this comprehensive narrative review was to identify and critically review the current evidence about the use of PPIs designed to improve women's mental well-being during the perinatal period. A systematic search of four online databases was conducted. Two intervention programmes have been identified. Both interventions were online-based and gratitude was the common PPI. The common target…

Listeria monocytogenes Differential Transcriptome Analysis Reveals Temperature-Dependent Agr Regulation and Suggests Overlaps with Other Regulons

2012

Listeria monocytogenes is a ubiquitous, opportunistic pathogenic organism. Environmental adaptation requires constant regulation of gene expression. Among transcriptional regulators, AgrA is part of an auto-induction system. Temperature is an environmental cue critical for in vivo adaptation. In order to investigate how temperature may affect AgrA-dependent transcription, we compared the transcriptomes of the parental strain L. monocytogenes EGD-e and its Delta agrA mutant at the saprophytic temperature of 25 degrees C and in vivo temperature of 37 degrees C. Variations of transcriptome were higher at 37 degrees C than at 25 degrees C. Results suggested that AgrA may be involved in the regu…

Molecular signature of Epstein Barr virus-positive Burkitt lymphoma and post-transplant lymphoproliferative disorder suggest different roles for Epst…

2014

Epstein Barr virus (EBV) infection is commonly associated with human cancer and, in particular, with lymphoid malignancies. Although the precise role of the virus in the pathogenesis of different lymphomas is largely unknown, it is well recognized that the expression of viral latent proteins and miRNA can contribute to its pathogenetic role. In this study, we compared the gene and miRNA expression profile of two EBV-associated aggressive B non-Hodgkin lymphomas known to be characterized by differential expression of the viral latent proteins aiming to dissect the possible different contribution of such proteins and EBV-encoded miRNAs. By applying extensive bioinformatic inferring and an exp…

Does Microfinance Cause or Reduce Suicides? Policy Recommendations for Reducing Borrower Stress

2011

At a time when suicides by microfinance borrowers in Andhra Pradesh are extensively discussed, this paper makes an initial tentative exploration into the impact of microfinance on suicides. Does MF reduce or increase suicides? Data limitations imply methodological limitations and provisional conclusions. The literature review, starting with Emile Durkheim, of research on suicides brings out the importance of psychological factors, divorce, and unemployment. We investigate time series data on suicides in India and find a just significantly positive correlation with male suicide rates and slightly negative correlations (not significant) with female suicide rates – but no relation between micr…
