Leaf Dry Matter Content Is Phylogenetically Conserved and Related to Environmental Conditions, Especially Wildfire Activity.

Leaf dry matter content (LDMC) is an important determinant of plant flammability. Investigating global patterns of LDMC could provide insights into worldwide plant flammability patterns, informing wildfire management. We characterised global patterns of LDMC across 4074 species from 216 families, revealing that phylogenetic and environmental constraints influence LDMC.

Guideline Concordant Extended Pharmacologic Venous Thromboembolism Prophylaxis Utilization After Colorectal Cancer Resection Is Low Regardless of Patient Factors or Hospital Characteristics.

Background: Venous thromboembolism after colorectal cancer resection is common and highly morbid. Extended pharmacologic venous thromboembolism prophylaxis after cancer surgery lowers venous thromboembolism risk and is recommended by major professional societies. Adherence is low in contemporary local and regional studies.

Exercise testing in clinical context: Reference ranges for interpreting anaerobic threshold as an outcome for congenital heart disease patients.

Background: Change in the oxygen consumption (VO) at the ventilatory anaerobic threshold (VAT) is an important outcome in research studies of children with congenital heart disease (CHD). The range of values reported by different raters for any given VAT is needed to contextualize a change in VAT in intervention studies.

Methods: Sixty maximal cardiopulmonary exercise tests (CPET) for CHD patients 8-21 years old were independently reviewed by six exercise physiologists and four pediatric cardiologists.

Self-sensitized photodegradation and adsorption of aqueous malachite green dye using one-dimensional titanium oxide nanofilaments.

Truly one-dimensional titanium oxide nanofilaments with a lepidocrocite structure (1DLs) were explored in the adsorption and photocatalytic degradation of aqueous malachite green (MG), a toxic polluting dye. Decolorization is monitored by ultraviolet-visible spectroscopy, and mineralization is confirmed by total organic carbon analysis. The 1DL/MG flocs are characterized by scanning electron microscopy and X-ray diffraction.

Combined Exercise and Mindset Training During a Pediatric Cardiac Fitness and Rehabilitation Program Benefits Youth with a Range of Congenital Heart Disease.

Pediatric cardiac fitness and rehabilitation programs vary widely in structure and content. The Cardiac Fitness Program (CFP) is built on traditional training pillars of aerobic, strength, and flexibility, and adds a fourth, training a positive mindset. This study assesses whether the systematic and comprehensive framework of the CFP results in broad benefits for a range of patients with congenital heart disease (CHD).

Extended Pharmacologic Prophylaxis for Venous Thromboembolism After Colon Cancer Surgery Is Associated With Improved Long-term Survival: A Natural Experiment in the Chemotherapeutic Benefit of Heparin Derivatives.

Objective: This large database study assessed whether extended pharmacologic prophylaxis for venous thromboembolism after colon cancer resection was associated with improved oncologic survival.

Background: Heparin derivatives may confer an antineoplastic effect via a variety of mechanisms (eg, inhibiting angiogenesis in the tumor microenvironment). Studies evaluating the oncologic benefit of heparin and its derivatives have been limited in postsurgical patients.

Future patterns in burden and incidence of squamous cell carcinoma of the anus in the United States, 2001-2035.

Squamous cell carcinoma of the anus (SCCA) incidence has been rising in the United States, particularly among older adults (≥65 years). We estimated the impact of this rise on future burden (through 2035) using age-period-cohort modeling. The SCCA burden (cases/year) is expected to rise, reaching approximately 2700 among men and approximately 7000 among women in 2031-2035 (burden during 2016-2020 among men and women was approximately 2150 and approximately 4600), with most cases 65 years of age or older (61% in men and 70% in women in 2031-2035; from 40% and 46% in 2016-2020).

ABBV-319: a CD19-targeting glucocorticoid receptor modulator antibody-drug conjugate therapy for B-cell malignancies.

Glucocorticoids are key components of the standard-of-care treatment regimens for B-cell malignancy. However, systemic glucocorticoid treatment is associated with several adverse events. ABBV-319 is a CD19-targeting antibody-drug conjugate engineered to reduce glucocorticoid-associated toxicities while possessing 3 distinct mechanisms of action (MOA) to increase therapeutic efficacy: (1) antibody-mediated delivery of a glucocorticoid receptor modulator (GRM) payload to activate apoptosis, (2) inhibition of CD19 signaling, and (3) enhanced fragment crystallizable (Fc)-mediated effector function via afucosylation of the antibody backbone.

Predicting Accelerometer-Assessed Estimates of Adolescents' Multidimensional Physical Activity: A Self-Determination Theory Approach.

Based on the tenets in self-determination theory, a dual-process model of motivational processes was tested to predict accelerometer-assessed estimates of adolescents' light physical activity (LPA), moderate to vigorous physical activity (MVPA), and sedentary time. Here, we hypothesized that (a) perceptions of psychological need support for exercise would be positively associated with LPA and MVPA and negatively associated with sedentary time via exercise-related psychological need satisfaction and autonomous exercise motivation and (b) perceptions of psychological need thwarting for exercise would be negatively associated with LPA and MVPA and positively associated with sedentary time via exercise-related psychological need frustration and controlled exercise motivation. Adolescents (N = 338; 234 female) age 11-15 years (M = 12.

Genomic Analysis and Surveillance of Respiratory Syncytial Virus Using Wastewater-Based Epidemiology.

Respiratory syncytial virus (RSV) causes severe infections in infants, immunocompromised or elderly individuals resulting in annual epidemics of respiratory disease. Currently, limited clinical surveillance and the lack of predictable seasonal dynamics limit the public health response. Wastewater-based epidemiology (WBE) has recently been used globally as a key metric in determining prevalence of severe acute respiratory syndrome coronavirus 2 in the community, but its application to other respiratory viruses is limited.

Negative Social Exchanges During the Pandemic, Loneliness, and the Mediating Role of Stress and Feeling Misunderstood Among People at High-Risk for COVID-19 Related Complications.

The goal of this study was to investigate the links between social interactions and mental health for people who are high-risk for COVID-19 complications. Specifically, we tested the relationships between negative social exchanges during the pandemic and loneliness through two mediators: stress and feeling misunderstood about one's health status. Data were collected via Amazon's MTurk from participants ( = 271) who self-identified as being high-risk for COVID-19.

Thyroid Hormone Suppresses Medulloblastoma Progression Through Promoting Terminal Differentiation of Tumor Cells.

Hypothyroidism is commonly detected in patients with medulloblastoma (MB). A possible link between thyroid hormone (TH) signaling and MB pathogenicity has not been reported. Here, we find that TH plays a critical role in promoting tumor cell differentiation.

Blood and urine multi-omics analysis of the impact of e-vaping, smoking, and cessation: from exposome to molecular responses.

Cigarette smoking is a major preventable cause of morbidity and mortality. While quitting smoking is the best option, switching from cigarettes to non-combustible alternatives (NCAs) such as e-vapor products is a viable harm reduction approach for smokers who would otherwise continue to smoke. A key challenge for the clinical assessment of NCAs is that self-reported product use can be unreliable, compromising the proper evaluation of their risk reduction potential.

Pangenome graphs improve the analysis of structural variants in rare genetic diseases.

Rare DNA alterations that cause heritable diseases are only partially resolvable by clinical next-generation sequencing due to the difficulty of detecting structural variation (SV) in all genomic contexts. Long-read, high fidelity genome sequencing (HiFi-GS) detects SVs with increased sensitivity and enables assembling personal and graph genomes. We leverage standard reference genomes, public assemblies (n = 94) and a large collection of HiFi-GS data from a rare disease program (Genomic Answers for Kids, GA4K, n = 574 assemblies) to build a graph genome representing a unified SV callset in GA4K, identify common variation and prioritize SVs that are more likely to cause genetic disease (MAF < 0.

Measuring flammability of crops, pastures, fruit trees, and weeds: A novel tool to fight wildfires in agricultural landscapes.

Fires on agricultural land account for 8-11 % of the total number of fires that occur globally. These fires burn through various crops, pastures, and native vegetation on farms, causing economic and environmental losses. Fire management on farms will be aided by understanding the flammability of plant species as this would allow the design of low-flammability agricultural landscapes, but flammability data on large numbers of agricultural species are lacking.

A spectroscopic liquid biopsy for the earlier detection of multiple cancer types.

Background: A rapid, low-cost blood test that can be applied to reliably detect multiple different cancer types would be transformational.

Methods: In this large-scale discovery study (n = 2092 patients) we applied the Dxcover® Cancer Liquid Biopsy to examine eight different cancers. The test uses Fourier transform infrared (FTIR) spectroscopy and machine-learning algorithms to detect cancer.

Perioperative Malnutrition.

A 61-year-old man presented with penetrating Crohn's ileocolitis and neoterminal ileal fibrostenotic stricture. He developed an anastomotic leak after a redo ileocolic resection and now has a chronic low-output enterocutaneous fistula. He was transferred from an outside institution for further management and is currently without Crohn's disease (CD)-related medical therapy.

Global serum profiling: an opportunity for earlier cancer detection.

The advances in cancer research achieved in the last 50 years have been remarkable and have provided a deeper knowledge of this disease in many of its conceptual and biochemical aspects. From viewing a tumor as a 'simple' aggregate of mutant cells and focusing on detecting key cell changes leading to the tumorigenesis, the understanding of cancer has broadened to consider it as a complex organ interacting with its close and far surroundings through tumor and non-tumor cells, metabolic mechanisms, and immune processes. Metabolism and the immune system have been linked to tumorigenesis and malignancy progression along with cancer-specific genetic mutations.
