Photophysical Studies of a Zr(IV) Complex with Two Pyrrolide-Based Tetradentate Schiff Base Ligands.

The reaction of two equivalents of ,-bis(2-pyrrolylmethylidene)-1,2-phenylenediamine (Hbppda) with tetrabenzylzirconium provided the air- and moisture-stable eight-coordinate complex Zr(bppda). Temperature-dependent steady-state and time-resolved emission spectroscopy established weak photoluminescence (Φ = 0.4% at 293 K) by a combination of prompt fluorescence and thermally activated delayed fluorescence (TADF) upon visible light excitation at and around room temperature.

Contemporary Practice of Anemia Treatment Among Dialysis Patients in the United States.

Introduction: The treatment of anemia is a major activity in the care of patients undergoing maintenance hemodialysis (HD). The comparative effectiveness of new pharmacologic treatments, relative to erythropoiesis-stimulating agents (ESAs), should be anticipated on the bases of controlled trials and current practice. We describe the contemporary practice of anemia treatment in a national cohort of patients undergoing maintenance HD.

The Critical Value of Telepathology in the COVID-19 Era.

Background: Telepathology, which includes the use of telecommunication links, helps enable transmission of digital pathology images for primary diagnosis, quality assurance, education, research, or second opinion diagnoses.

Observations: This review covers all aspects of telepathology implementation, including the selection of platforms, budgets and regulations, validation, implementation, education, quality monitoring, and the potential to improve practice. Considering the long-term trends, the lessons of the COVID-19 pandemic, and the potential for future pandemics or other disasters, the validation and implementation of telepathology remains a reasonable choice for laboratories looking to improve their practice.

Organometallic Intermediates in the Synthesis of Photoluminescent Zirconium and Hafnium Complexes with Pyridine Dipyrrolide Ligands.

The two commercially available zirconium complexes tetrakis(dimethylamido)zirconium, Zr(NMe), and tetrabenzylzirconium, ZrBn, were investigated for their utility as starting materials in the synthesis of bis(pyridine dipyrrolide)zirconium photosensitizers, Zr(PDP). Reaction with one equivalent of the ligand precursor 2,6-bis(5-methyl-3-phenyl-1-pyrrol-2-yl)pyridine, HPDP, resulted in the isolation and structural characterization of the complexes (PDP)Zr(NMe)thf and (PDP)ZrBn, which could be converted to the desired photosensitizer Zr(PDP) upon addition of a second equivalent of HPDP. Using the more sterically encumbered ligand precursor 2,6-bis(5-(2,4,6-trimethylphenyl)-3-phenyl-1-pyrrol-2-yl)pyridine, HPDP, only ZrBn yielded the desired bis-ligand complex Zr(PDP).

On-Site Nurse-Led Cancer Genetics Program Increases Cancer Genetic Testing Completion in Black Veterans.

Purpose: Telegenetics services can expand access to guideline-recommended cancer genetic testing. However, access is often not distributed equitably to all races and ethnicities. We evaluated the impact of an on-site nurse-led cancer genetics service in a diverse Veterans Affairs Medical Center (VAMC) oncology clinic on likelihood of germline testing (GT) completion.

A Redox Transmetalation Step in Nickel-Catalyzed C-C Coupling Reactions.

Ni-catalyzed C-H functionalization reactions are becoming efficient routes to access a variety of functionalized arenes, yet the mechanisms of these catalytic C-C coupling reactions are not well understood. Here, we report the catalytic and stoichiometric arylation reactions of a nickel(II) metallacycle. Treatment of this species with silver(I)-aryl complexes results in facile arylation, consistent with a redox transmetalation step.

COVID-19 Cycle Threshold/Cycle Number Testing at a Community Living Center.

Background: COVID-19 imposes a special risk to the nursing home population, including community living centers (CLCs) for veterans. Cycle threshold/cycle number (CT/CN) values obtained by serial reverse transcriptase polymerase chain reaction (RT-PCR) testing could yield valuable information about viral load and potential infectiousness. Serial testing for COVID-19 with CT/CN correlates in a nursing home population during an outbreak has not yet been reported in the literature.

Long-lived photoluminescence from an eight-coordinate zirconium(IV) complex with four 2-(2'-pyridyl)pyrrolide ligands.

The photoluminescent eight-coordinate zirconium complex Zr(PMP) supported by four monoanionic 2-(2'-pyridine)pyrrolide ligands was synthesized. This molecule shows dual emission fluorescence and phosphorescence with an overall quantum efficiency of 4% at room temperature in solution. The phosphorescence lifetime is dependent on concentration, indicating excimer formation at higher concentrations, and reaches almost 800 μs at high dilution.

Genomics-informed delineation of conservation units in a desert amphibian.

Delineating conservation units (CUs, e.g., evolutionarily significant units, ESUs, and management units, MUs) is critical to the recovery of declining species because CUs inform both listing status and management actions.

Compliance with the Current NCCN Guidelines and Its Critical Role in Pancreatic Adenocarcinoma.

Objectives: Since 2019, the National Comprehensive Cancer Network (NCCN) has recommended genetic testing for patients diagnosed with pancreatic adenocarcinoma that includes universal germline testing and tumor gene profiling for metastatic, locally advanced, or recurrent disease. However, testing compliance with this guideline has not yet been published in the English literature.

Methods: A quality assurance/quality improvement retrospective review was done to identify patients diagnosed with pancreatic adenocarcinoma from January 2019 to February 2021 to include the patient's clinical status and genetic test results.

Long-Lived Photoluminescence of Molecular Group 14 Compounds through Thermally Activated Delayed Fluorescence.

Photoluminescent molecules exploiting the sizable spin-orbit coupling constants of main group metals and metalloids to access long-lived triplet excited states are relatively rare compared to phosphorescent transition metal complexes. Here we report the synthesis of three air- and moisture-stable group 14 compounds E(PDP), where E = Si, Ge, or Sn and [PDP] is the doubly deprotonated form of 2,6-bis(5-methyl-3-phenyl-1-pyrrol-2-yl)pyridine. In solution, all three molecules exhibit exceptionally long-lived triplet excited states with lifetimes in the millisecond range and show highly efficient photoluminescence (Φ ≤ 0.

Trends in characteristics and outcomes among US adults hospitalised with COVID-19 throughout 2020: an observational cohort study.

Practical Risk Scoring System for Predicting Severity of COVID-19 Disease.

Objectives: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19 disease, has become an international pandemic with numerous casualties. It had been noted that the severity of the COVID-19 disease course depends on several clinical, laboratory, and radiological factors. This has led to risk scoring systems in various populations such as in China, but similar risk scoring systems based on the American veteran population are sparse, particularly with the vulnerable Veteran population.

Hospital and Laboratory Practice in an Integrated Medical System for HIV Infection Prevention Interventions at a Veteran Affairs Medical Center.

Objective: The impact of sexually transmitted infection (STI) results on prompting clinicians to consider pre-exposure prophylaxis (PrEP) indication is sparse in the literature, particularly for veterans.

Methods: A retrospective search from June 2018 to February 2020 was performed to identify all patients who were HIV-negative at a regional Veteran Affairs Medical Center with a positive STI test result and review the medical chart of these patients.

Results: We identified 220 veterans who were HIV-negative with a positive STI test result.

High Magnetic Anisotropy of a Square-Planar Iron-Carbene Complex.

Among Earth-abundant catalyst systems, iron-carbene intermediates that perform C-C bond forming reactions such as cyclopropanation of olefins and C-H functionalization via carbene insertion are rare. Detailed descriptions of the possible electronic structures for iron-carbene bonds are imperative to obtain better mechanistic insights and enable rational catalyst design. Here, we report the first square-planar iron-carbene complex (PDP)Fe(CPh), where [PDP] is the doubly deprotonated form of [2,6-bis(5-(2,4,6-trimethylphenyl)-3-phenyl-1-pyrrol-2-yl)pyridine].

Ethnicity, Comorbid Medical Conditions, and SARS-CoV-2 Test Cycle Thresholds in the Veteran Population.

Background And Aims: It has been documented that African Americans have been significantly affected by COVID-19 infection due to systemic societal factors, which may lead to increases in comorbid medical history and subsequently vulnerability to having higher viral loads as measured by the cycle threshold/number (CT/CN) values by reverse transcriptase polymerase chain reaction (RT-PCR). Differences in CT/CN values by ethnicity and comorbid medical history could play an important role in public health research, particularly in elucidating the reasons for differential public health outcomes by ethnicity, as viral loads are known to correlate with disease severity. However, there is a gap in the literature regarding CT/CN values by ethnicity and comorbid medical history.

Reducing False-Positive Results With Fourth-Generation HIV Testing at a Veterans Affairs Medical Center.

Background: In 2006, the Centers for Disease Control and Prevention issued guidelines advocating routine HIV screening for all patients. However, false-positive results are a potential patient care threat for low-risk populations even with accurate screening assays. A reduction in HIV false-positive screening results can potentially be seen by switching from the third-generation to a more sensitive and specific fourth-generation screening assay.

Growing the Youth Olympic Games: Comparing Millennial Generation Sport Festival Engagement.

Despite the continued growth of the Olympic Games (OG), the Youth Olympic Games (YOG) has received minimal attention from mainstream media since its introduction in 2010. The purpose of this study was to examine and compare event awareness and consumption intention for the 2012 Winter YOG to two international sport events occurring in the same year. A survey instrument was utilized to examine and compare event awareness, consumption intention, and logo identification for three international sport events within a millennial generation sample.
