Learning, economies of scale, and knowledge gap effects on power generation technology cost improvements.

Cost reductions are essential for accelerating clean technology deployment. Because multiple factors influence costs, traditional one-factor learning models, solely relying on cumulative installed capacity as an explanatory variable, may oversimplify cost dynamics. In this study, we disentangle learning and economies of scale effects at unit and project levels and introduce a knowledge gap concept to quantify rapid technological change's impact on costs.

Ventilator-Associated Pneumonia in Low- and Middle-Income vs. High-Income Countries: The Role of Ventilator Bundle, Ventilation Practices, and Healthcare Staffing.

Background: Ventilator-associated pneumonia (VAP) rates are higher in low- and middle-income countries (LMICs) than in high-income countries (HICs).

Research Question: Could differences in ventilator bundle adherence, ventilation practices, and critical care staffing be driving variations in VAP risk between LMICs and HICs?

Study Design And Methods: This secondary analysis of the multicenter, international CERTAIN study included mechanically ventilated patients at risk for VAP from eleven LMICs and five HICs. We included oral care, head-of-bed elevation, spontaneous breathing assessments, and sedation breaks in the ventilator bundle.

Exploring the Role of Glycine Metabolism in Coronary Artery Disease: Insights from Human Genetics and Mouse Models.

Circulating glycine levels have been associated with reduced risk of coronary artery disease (CAD) in humans but these associations have not been observed in all studies. We evaluated whether the relationship between glycine levels and atherosclerosis was causal using genetic analyses in humans and feeding studies in mice. Serum glycine levels were evaluated for association with risk of CAD in the UK Biobank.

Have gender and ethnic disparities in ophthalmology disappeared? Insights from a workforce-based study in Israel (2006-2021).

Background: Workforce diversity in healthcare has been shown to improve the quality of patient care. A paucity of data exists globally on this subject in ophthalmology. The purpose of this study was to analyze nationwide trends in gender-, ethnic- and country of graduation disparities among ophthalmologists in Israel.

COVID-19 Vaccinations, Infections, and Outcomes Among 784 People Living with HIV.

Introduction: Variants of COVID-19 are responsible for 700 million infections and 7 million deaths worldwide. Vaccinations have high efficiency in preventing infection and secondary benefits of reducing COVID-19 hospital admissions, attenuating disease severity and duration of illness. Conflicting reports were published regarding COVID-19 among PLWH.

Identification of strain-specific cues that regulate biofilm formation in .

Unlabelled: Members of the gut microbiome encounter a barrage of host- and microbe-derived microbiocidal factors that must be overcome to maintain fitness in the intestine. The long-term stability of many gut microbiome strains within the microbiome suggests the existence of strain-specific strategies that have evolved to foster resilience to such insults. Despite this, little is known about the mechanisms that mediate this resistance.

Associations of adolescent obesity with hypertension, diabetes mellitus and polycystic ovaries in Arabs and Jews in Israel-a nationwide study.

Background: Previous studies on the association of adolescent obesity with comorbid diseases in Israel were conducted predominantly in the Israeli Jewish population.

Goal: To compare associations of adolescent obesity with Hypertension (HTN), Diabetes Mellitus type 2 (DM2), and Polycystic ovaries (PCO), singly or in combination, between Arabs and Jews in Israel.

Methods: A cross-sectional study of 313,936 Arab adolescents aged 14-19 years between the years 2007-2022, and 289,616 adolescents in a matched Jewish comparison group.

Simulated Gastrointestinal Fluids Impact the Stability of Polymer-Functionalized Selenium Nanoparticles: Physicochemical Aspects.

Background: Selenium (Se) is a vital micronutrient for maintaining homeostasis in the human body. Selenium nanoparticles (SeNPs) have demonstrated improved bioavailability compared to both inorganic and organic forms of Se. Therefore, supplementing with elemental Se in its nano-form is highly promising for biomedical applications related to Se deficiency.

Ablative radiofrequency microplasma for lateral dermatochalasis-indications and treatment recommendations.

To determine in which cases ablative radiofrequency microplasma is preferred for the treatment of lateral dermatochalasis over a surgical approach as well as discussing each method's benefits and limitations. Twenty-one patients underwent 3 interventions of plasma exeresis. Photographic and RCM images were acquired at baseline and 4 weeks after final plasma exeresis.

Calcifediol and paricalcitol as adjunctive therapies for HSV-1 keratitis and corneal perforation: A case report.

Rationale: Herpes simplex virus 1 establishes a latent infection in trigeminal ganglia. Reactivation causes cold sores, as well as viral keratitis. The purpose of this study was to report potential benefits of using active vitamin D receptor ligands (VDR-agonists) as adjunctive therapies for the treatment of infectious corneal perforations, and prevention of HSV recurrence.

Overweight and obesity among Israeli adolescents and the risk for serious morbidity in early young adulthood: a nationwide retrospective cohort study.

Background: Morbidities related to obesity are usually associated with its severity and duration. Yet, the onset of serious morbidities in early adulthood among otherwise healthy adolescents with obesity is understudied. We aimed to investigate the association between adolescent BMI and serious morbidities before age 25 years.

Kinetics of imidazole propionate from orally delivered histidine in mice and humans.

Imidazole Propionate (ImP), a gut-derived metabolite from histidine, affects insulin signaling in mice and is elevated in type 2 diabetes (T2D). However, the source of histidine and the role of the gut microbiota remain unclear. We conducted an intervention study in mice and humans, comparing ImP kinetics in mice on a high-fat diet with varying histidine levels and antibiotics, and assessed ImP levels in healthy and T2D subjects with histidine supplementation.

CHADS-VASc Score in Predicting Visual Acuity Outcomes Following Retinal Vein Occlusion.

To find whether the CHADS-VASc score, a system for stratifying stroke risk among patients with atrial fibrillation, correlates with visual acuity prognosis following retinal vein occlusion (RVO). This retrospective study included 83 eyes of 83 patients with a diagnosis of branch or central RVO between June 2017 and August 2022 with at least 12 months of follow-up in Assuta Ashdod Medical Center, Ashdod, Israel. The patients were divided into three groups, with CHADS-VASc scores of 0-2 ( = 31), 3-5 ( = 45), or 6-9 ( = 7).

The Association of Weight Categories in Adolescence with Cardiovascular Morbidity in Young Adult Israeli Arabs-A Nationwide Study.

The health consequences of adolescent obesity are understudied in young adult Israeli Arabs. We aimed to evaluate the association of weight categories during adolescence with hypertension (HTN), diabetes mellitus type 2 (DM2), and the composite endpoint of ischemic stroke (IS), myocardial infarction (MI), and heart failure (HF) in young adult Israeli Arabs on a nationwide level. A retrospective cohort study of 53,726 Arab adolescents born from 1988-1992 was conducted.

Measurement of mid-upper arm circumference to screen for childhood malnutrition: General applicability and use in special populations.

Since the development of consensus-recommended indicators for pediatric malnutrition in 2014, screening and diagnosis of pediatric malnutrition have improved, but the indicators are not always used; malnutrition continues to be underdiagnosed in some community and healthcare settings. In particular, mid-upper arm circumference (MUAC) is underused as a screening indicator for pediatric malnutrition, despite its unique advantages and usefulness in several clinical situations. In December 2022, a scientific roundtable was held to bring together several experts in pediatric malnutrition.

Iron deficiency anemia among infants: a retrospective cohort study.

Postnatal iron deficiency, especially from ages 6 to 24 months, has long-term consequences lasting into adolescence and adulthood. We aimed to characterize iron deficiency anemia among infants from one central Israeli district by demographic and laboratory parameters. A retrospective chart review was performed on all infants from a single district who had undergone a complete blood count as part of a routine survey for iron deficiency anemia during 2010-2021.
