Background: Treatment of gestational diabetes mellitus (GDM) has been shown to improve both maternal and neonatal outcomes. For women with GDM who require glucose-lowering medication, insulin is regarded as the drug of choice by most medical societies. Oral therapy, with metformin or glibenclamide, is a reasonable alternative in certain medical circumstances.

We aimed to investigate the correlation between total deceleration area (TDA), neonatal birthweight and neonatal acidemia in vacuum extractions (VEs). This is a retrospective study in a tertiary hospital, including VE performed due to non-reassuring fetal heart rate (NRFHR). Electronic fetal monitoring during the 120 min preceding delivery was interpreted by two obstetricians who were blinded to neonatal outcomes.

Aim: Delayed-onset postpartum preeclampsia (PET) is defined as a new diagnosis of preeclampsia presenting 48 h to 6 weeks postpartum. This disorder is infrequent and associated with a higher incidence of complications as compared to antepartum PET. There seems to be a need to further characterize this disorder.

The study investigates the acquisition of Hebrew zero and pronominal subjects in the context of first and second person. We provide distributional evidence relative to verb tense, number, person, and conversational utterance type, in a peer-talk corpus (2;0-8;0 years). Findings show that acquisition starts early on, that verb inflectional morphology is crucial for the development of pronominal subjects, and that communicative contexts affect subject realization.

This retrospective cohort study evaluated pregnancy outcomes and similarities between pairs of nulliparous sisters with a singleton fetus who delivered between 2013 and 2020. The “Sister-1 group” was defined as the sibling who delivered first, while the “Sister-2 group” included the siblings who gave birth after Sister-1. Obstetrical complications and delivery outcomes were compared.

Educational virtual environments (EVEs) are defined by their features of immersion (degree of sensory engagement) and fidelity (degree of realism). Increasingly, EVEs are being used for career development and training purposes, which we refer to as career-oriented EVEs. However, little research has examined the effects of immersion and fidelity on career-related outcomes, like self-efficacy and interests, and the learning dynamics that may influence these outcomes.

Objective: To evaluate objective (saliva cortisol) and subjective (questionnaire) stress levels during the Coronavirus disease (COVID-19) pandemic compared to before the pandemic and their effects on obstetric and neonatal outcomes.

Methods: This cohort study included 36 women with low-risk, singleton, term deliveries at a tertiary academic center during the COVID-19 pandemic and 49 who delivered before. Physiological stress was evaluated with salivary cortisol measurements, and emotional stress with stress scale questionnaires (0-10) during active and full dilation stages of labor, and 2-min postpartum.

Children approach verb learning in ways that are specific to their native language, given the differential typological organization of verb morphology and lexical semantics. Parent-child interaction is the arena where children's socio-cognitive abilities enable them to track predictive relationships between tokens and extract linguistic generalizations from patterns and regularities in the ambient language. The current study examines how the system of Hebrew verbs develops as a network over time in early childhood, and the dynamic role of input-output adaptation in the network's increasing complexity.

Bad Temptation.

We study a static self-control model in which an agent's preference, temptation ranking, and cost of self-control drive her choices among a finite set of options. We show that it is without loss to assume that the agent's temptation ranking is the opposite of her preference. We characterize the model by relaxing the Weak Axiom of Revealed Preference (WARP), and exploit WARP violations to identify the model's parameters.

Subclinical hypothyroidism (SCH) is defined as an elevated serum thyroid-stimulating hormone (TSH) level with a normal serum-free thyroxine (FT4) level. SCH has been associated with an increased risk of adverse cardiovascular outcomes. We investigated possible associations of unknown SCH with in-hospital outcomes and short- and long-term all-cause mortality in a large cohort of patients with ST segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI).

The current study examined the factors underlying native Hebrew speakers' ability to learn homophonous affix spelling. It takes a novel view in investigating the effect of morpho-orthographic complexity of affix representation on the development of affix spelling across the school years. The role of five morpho-orthographic principles in homophonous affix letter spelling was studied: (i) morpho-orthographic transparency; (ii) affix letter prevalence; (iii) morpho-phonological competition; (iv) overtness of the phonological-orthographic link; and (v) phono-morpho-orthographic consistency.

Background: Data suggest that subclinical hypothyroidism (SCH) is associated with progression of chronic renal disease; however, no study to date has assessed the possible relation between SCH and acute deterioration of renal function.

Objectives: To investigate the possible relation between SCH and acute kidney injury (AKI) in a large cohort of patients with ST-elevation myocardial infarction (STEMI) treated with primary coronary intervention (PCI).

Methods: We evaluated thyroid stimulating hormone (TSH) and free T4 levels of 1591 STEMI patients with no known history of hypothyroidism or thyroid replacement treatment who were admitted to the coronary care unit (October 2007-August 2017).

This study examined early Hebrew verb acquisition, highlighting CDS-CS relations across inflectional and derivational verb learning. It was carried out on a corpus of longitudinal dense dyadic interactions of two Hebrew-speaking toddlers aged 1;8-2;2 and their parents. Findings revealed correlated patterns within and between CDS and CS corpora in terms of verbs, structural root categories, and their components (roots, binyan conjugations, and derivational verb families), and clear relations between lexical-derivational development and inflectional growth in input-output relations, measured by MSP.

Many individuals perceive digital monitoring to be an inherently negative practice that invades privacy, but recent research suggests that it has positive effects for workers under certain circumstances. This review expands upon existing digital monitoring frameworks by adopting a psychological perspective to explain individual and contextual variation in monitoring reactions. To do so, we identify person characteristics (e.

Background: Current guidelines for the treatment of ST-segment elevation myocardial infarction (STEMI) recommend a door-to-balloon time (DBT) of ≤ 90 min for patients undergoing primary percutaneous coronary intervention (PCI). We aimed to investigate the possible impact of further reduction in DBT intervals beyond the 90 min cutoff on short and long-term outcomes among STEMI patients undergoing primary PCI.

Methods: We retrospectively studied 889 STEMI patients (median age 61 years, 83% men) who underwent successful primary PCI and had a DBT of ≤ 90 min.

Cardiotoxicity from cancer therapy has become a leading cause of morbidity and mortality in cancer survivors. The most commonly used definition is cancer therapeutic related cardiac dysfunction defined as a left ventricular ejection fraction (LVEF) reduction of >10%, to a value below 50%. However, according to the recent American and European Society of Echocardiography, global longitudinal strain (GLS) is the optimal parameter for early detection of subclinical left ventricular dysfunction.
