Introduction: The study objective was to describe characteristics and utilization patterns of tirzepatide users with type 2 diabetes (T2D) using the Healthcare Integrated Research Database in the USA.

Methods: Adults (≥18 years) included had T2D diagnosis; ≥1 tirzepatide claim (May 2022-January 2023; first claim date = index date); and continuous medical and pharmacy enrollment during the 6-month baseline and follow-up periods from the index date. Baseline demographics, clinical characteristics, and 6-month follow-up dosing and treatment patterns were summarized descriptively.

No Future Growth Enhancement Expected at the Northern Edge for European Beech due to Continued Water Limitation.

With ongoing global warming, increasing water deficits promote physiological stress on forest ecosystems with negative impacts on tree growth, vitality, and survival. How individual tree species will react to increased drought stress is therefore a key research question to address for carbon accounting and the development of climate change mitigation strategies. Recent tree-ring studies have shown that trees at higher latitudes will benefit from warmer temperatures, yet this is likely highly species-dependent and less well-known for more temperate tree species.

Real-world treatment patterns, resource utilization and costs in biliary tract cancers in the USA.

To evaluate real-world treatment patterns, survival and healthcare-resource utilization in US patients with advanced biliary tract cancers (BTC) receiving systemic therapy. This study used claims data from the Healthcare Integrated Research Database (HIRD®) linked to clinical data from the Cancer Care Quality Program (January 1, 2015-September 30, 2020). Of 413 patients, 84.

Depressed-cladding thulium-doped fiber for applications below 1800 nm.

We present a thulium-doped silica fiber, featuring a depressed cladding, for applications at wavelengths below 1800 nm. The depressed cladding is used as a distributed filter suppressing amplified spontaneous emission at longer wavelengths, which helps promote emission at shorter wavelengths. We describe the fiber design process that was carried out by using a combination of numerical methods.

Mechanistic insights into the biological activity of S-Sulfocysteine in CHO cells using a multi-omics approach.

S-Sulfocysteine (SSC), a bioavailable L-cysteine derivative (Cys), is known to be taken up and metabolized in Chinese hamster ovary (CHO) cells used to produce novel therapeutic biological entities. To gain a deeper mechanistic insight into the SSC biological activity and metabolization, a multi-omics study was performed on industrially relevant CHO-K1 GS cells throughout a fed-batch process, including metabolomic and proteomic profiling combined with multivariate data and pathway analyses. Multi-layered data and enzymatical assays revealed an intracellular SSC/glutathione mixed disulfide formation and glutaredoxin-mediated reduction, releasing Cys and sulfur species.

Real-world treatment modalities, health care resource utilization, and costs among commercially insured patients with newly diagnosed major depressive disorder in the United States.

In the United States, major depressive disorder (MDD) is one of the most prevalent mental health disorders. Treatment guidelines for MDD recommend pharmacologic and nonpharmacologic therapies tailored to the patient's disease severity, level of function, and comorbid health conditions. While previous studies examined real-world pharmacologic treatment patterns and costs among patients with MDD, few have examined the use of nonpharmacologic treatments and their association with health care resource utilization (HCRU) and cost.

Skeletal muscle delimited myopathy and verapamil toxicity in SUR2 mutant mouse models of AIMS.

ABCC9-related intellectual disability and myopathy syndrome (AIMS) arises from loss-of-function (LoF) mutations in the ABCC9 gene, which encodes the SUR2 subunit of ATP-sensitive potassium (K ) channels. K channels are found throughout the cardiovascular system and skeletal muscle and couple cellular metabolism to excitability. AIMS individuals show fatigability, muscle spasms, and cardiac dysfunction.

A Twelve-Hundred-Year Stable Oxygen Isotope Chronology Constructed Using Subfossil Wood from Schwarzensee Lake, Austrian Alps.

This study presents a new stable oxygen isotope chronology, covering the years 800-2000 AD, constructed using modern and subfossil wood derived from trees growing around Lake Schwarzensee in Austria. The climatic signal imparted in the chronology is conditioned mainly by the direct influence of environmental factors on the isotopic signature of source water, which in turn is regulated by evaporation and condensation mechanisms. The second driver of stable oxygen isotope is the physiological response of trees to changing weather conditions, most importantly rates of transpiration.

Identification of inadequate responders to advanced therapy among commercially-insured adult patients with Crohn's disease and ulcerative colitis in the United States.

Background: The purpose of this analysis was to assess the frequency of inadequate response over 1 year from advanced therapy initiation among patients with Crohn's disease (CD) or ulcerative colitis (UC) in the United States using a claims-based algorithm. Factors associated with inadequate response were also analyzed.

Methods: This study utilized claims data of adult patients from the HealthCore Integrated Research Database (HIRD) from January 01, 2016 to August 31, 2019.

Temperature-dependent cross section spectra for thulium-doped fiber lasers.

An investigation on the temperature dependence of spectroscopic parameters of trivalent thulium ions is important for the design of high-power, thulium-doped fiber lasers and amplifiers. In this Letter, the thulium absorption/emission cross sections are determined in the spectral range 700-2200 nm and in the temperature range from -196°C to 300°C. The spectra are obtained from the absorption and emission measurements of a thulium-doped fiber and from measured thulium concentration profiles.

Real-world treatment patterns and use of adjunctive pain and anti-inflammatory medications among patients with psoriatic arthritis treated with IL-17A inhibitors in the United States.

Much of the current research on treatment patterns and use of adjunctive pain and anti-inflammatory medications among patients living with psoriatic arthritis (PsA) predates the approval and uptake of IL (interleukin)-17A inhibitors. To compare real-world treatment patterns and use of adjunctive pain and antiinflammatory medications between patients with PsA initiating the IL-17A inhibitors, ixekizumab and secukinumab, in a US-managed care population. We conducted a retrospective cohort study using the HealthCore Integrated Research Database.

Investigation and modelling of the pyrolysis kinetics of industrial biomass wastes.

Pyrolysis of the waste organic fraction is expected to be a central element to meet the primary energy demand in future: it increases the impact of renewable energy sources on the power generation sector and allows the amount of waste to be reduced, putting an end to landfills. In the present study, kinetic studies on the pyrolysis of biomass wastes are carried out. Two kinds of industrial organic waste are investigated: brewery spent grain (BSG) and medium-density fiberboard (MDF).

Complement activation products vs standard ANA testing: Treatment outcomes, diagnosis, and economic impact (CAPSTONE) in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a complex clinical diagnosis historically aided by imperfect biomarkers. The advent of a multianalyte assay panel incorporating innovative cell-bound complement activation markers necessitates a comparison of its clinical utility to conventional autoantibodies for the diagnosis and treatment of SLE. To compare the likelihood of SLE diagnosis, SLE treatment initiation, and the downstream impact on health care utilization among patients tested with AVISE Lupus (AVISE) vs standard-of-care laboratory testing with the traditional antinuclear antibody (ANA) testing strategy cohort (tANA).

The distal C terminus of the dihydropyridine receptor β subunit is essential for tetrad formation in skeletal muscle.

The skeletal muscle dihydropyridine receptor (DHPR) β1a subunit is indispensable for full trafficking of DHPRs into triadic junctions (i.e., the close apposition of transverse tubules and sarcoplasmic reticulum [SR]), facilitation of DHPRα1S voltage sensing, and arrangement of DHPRs into tetrads as a consequence of their interaction with ryanodine receptor (RyR1) homotetramers.

Jet stream position explains regional anomalies in European beech forest productivity and tree growth.

The mechanistic pathways connecting ocean-atmosphere variability and terrestrial productivity are well-established theoretically, but remain challenging to quantify empirically. Such quantification will greatly improve the assessment and prediction of changes in terrestrial carbon sequestration in response to dynamically induced climatic extremes. The jet stream latitude (JSL) over the North Atlantic-European domain provides a synthetic and robust physical framework that integrates climate variability not accounted for by atmospheric circulation patterns alone.

Metabolism is a major driver of hydrogen isotope fractionation recorded in tree-ring glucose of Pinus nigra.

Stable isotope abundances convey valuable information about plant physiological processes and underlying environmental controls. Central gaps in our mechanistic understanding of hydrogen isotope abundances impede their widespread application within the plant and biogeosciences. To address these gaps, we analysed intramolecular deuterium abundances in glucose of Pinus nigra extracted from an annually resolved tree-ring series (1961-1995).

Comparative Effectiveness of Persistent Use of a Name-Brand Levothyroxine (Synthroid®) vs. Persistent Use of Generic Levothyroxine on TSH Goal Achievement: A Retrospective Study Among Patients with Hypothyroidism in a Managed Care Setting.

Introduction: Levothyroxine monotherapy (Synthroid® or multiple generic levothyroxine [GL] formulations) is standard treatment for hypothyroidism. Our objective was to compare effectiveness (as measured by achievement of thyroid-stimulating hormone [TSH] levels) and economic outcomes of Synthroid vs. any one of multiple GLs in patients with hypothyroidism.

Testosterone amplifies the negative valence of an agonistic gestural display by exploiting receiver perceptual bias.

Many animals communicate by performing elaborate displays that are incredibly extravagant and wildly bizarre. So, how do these displays evolve? One idea is that innate sensory biases arbitrarily favour the emergence of certain display traits over others, leading to the design of an unusual display. Here, we study how physiological factors associated with signal production influence this process, a topic that has received almost no attention.

Treatment Experiences with CDK4&6 Inhibitors Among Women with Metastatic Breast Cancer: A Qualitative Study.

Purpose: To describe patients' perspectives on the use of and potential challenges and barriers with adherence/persistence to cyclin-dependent kinase 4 and 6 inhibitors (CDK4&6i's) to treat metastatic breast cancer (MBC).

Methods: This qualitative study consisted of 60-minute semi-structured telephone interviews with patients with MBC in the US who were either current or recent CDK4&6i users, identified from administrative claims of survey-eligible commercial and Medicare Advantage patients in the HealthCore Integrated Research Database between November 1, 2018 and November 1, 2019. Patients were recruited by email and/or mailed letter.

Cost-Effectiveness of a Proteomic Test for Preterm Birth Prediction.

Background: Preterm birth (PTB) carries increased risk of short- and long-term health problems as well as higher healthcare costs. Current strategies using clinically accepted maternal risk factors (prior PTB, short cervix) can only identify a minority of singleton PTBs.

Objective: We modeled the cost-effectiveness of a risk-screening-and-treat strategy versus usual care for commercially insured pregnant US women without clinically accepted PTB risk factors.
