Testing for t(3;8) in MYC/BCL6-rearranged large B-cell lymphoma identifies a high-risk subgroup with inferior survival.

A reciprocal t(3;8) BCL6::MYC fusion is common in large B-cell lymphoma (LBCL) with MYC and BCL6 disruption. These pseudo-double-hit cases are not adverse, whereas t(3;8)-MYC/BCL6 lymphoma has an inferior prognosis relative to other MYC-rearranged LBCL.

Inhibition of Cyp1a Protects Mice against Anthracycline Cardiomyopathy.

Background: Anthracyclines such as doxorubicin (Dox) are highly effective anti-tumor agents, but their use is limited by dose-dependent cardiomyopathy and heart failure. Our laboratory previously reported that induction of cytochrome P450 family 1 (Cyp1) enzymes contributes to acute Dox cardiotoxicity in zebrafish and in mice, and that potent Cyp1 inhibitors prevent cardiotoxicity. However, the role of Cyp1 enzymes in chronic Dox cardiomyopathy, as well as the mechanisms underlying cardioprotection associated with Cyp1 inhibition, have not been fully elucidated.

Nest material preferences in wild hazel dormice : testing predictions from optimal foraging theory.

Obtaining nesting material presents an optimal foraging problem, collection of materials incurs a cost in terms of risk of predation and energy spent and individuals must balance these costs with the benefits of using that material in the nest. The hazel dormouse, is an endangered British mammal in which both sexes build nests. However, whether material used in their construction follows the predictions of optimal foraging theory is unknown.

Assessing Electronic Health Literacy at an Urban Academic Hospital.

Background: Residents of the Bronx suffer marked health disparities due to socioeconomic and other factors. The coronavirus disease 2019 pandemic worsened these health outcome disparities and health care access disparities, especially with the abrupt transition to online care.

Objectives: This study classified electronic health literacy (EHL) among patients at an urban, academic hospital in the Bronx, and assessed for associations between EHL levels and various demographic characteristics.

Circulating hemopexin modulates anthracycline cardiac toxicity in patients and in mice.

Anthracyclines such as doxorubicin (Dox) are effective chemotherapies, but their use is limited by cardiac toxicity. We hypothesized that plasma proteomics in women with breast cancer could identify new mechanisms of anthracycline cardiac toxicity. We measured changes in 1317 proteins in anthracycline-treated patients ( = 30) and replicated key findings in a second cohort ( = 31).

High prevalence of canine heartworm, Dirofilaria immitis, in pet dogs in south Texas, USA, with evidence of Aedes aegypti mosquitoes contributing to transmission.

Background: The canine heartworm Dirofilaria immitis, a filarioid nematode of dogs and other carnivores, is widespread in the USA and the world. Over 20 different mosquito species serve as intermediate hosts of D. immitis, but their contribution to transmission varies according to factors like host feeding patterns, geographic locations and climatic conditions.

Feasibility, acceptability, and utility of a nurse-led survivorship program for people with metastatic melanoma (MELCARE).

Purpose: Immune checkpoint inhibitors (ICIs) and targeted therapy (TT) have improved the survival of people with metastatic melanoma. We assessed the feasibility, acceptability, and utility of a novel model of nurse-led, telehealth-delivered survivorship care (MELCARE) for this survivor group.

Methods: People ≥ 18 years diagnosed with unresectable stage III or stage IV melanoma who were ≥ 6 months post initiation of ICI/TT with a radiological response suggestive of a long-term response to ICI/TT were recruited from a specialist melanoma centre in Australia.

Emphysematous Cystitis and Urinary Retention in a Male Patient With Diabetes Mellitus Type 2 Treated With Empagliflozin.

Objective: Emphysematous cystitis (EC) is a rare urinary tract infection (UTI) typically associated with severe diabetes in older women. We present a unique case of this gas-forming infection in a man with type 2 diabetes mellitus (T2DM) treated with empagliflozin. To the best of our knowledge, this is the first case report of EC associated with the use of a sodium-glucose cotransporter 2 inhibitor (SGLT2i).

5-FU Cardiotoxicity: Vasospasm, Myocarditis, and Sudden Death.

Purpose Of Review: 5-fluorouracil (5-FU) is one of the most common causes of cardiotoxicity associated with chemotherapy. The manifestations of 5-FU cardiotoxicity are diverse, and there are no established clinical guidelines addressing the diagnosis and management of this condition. Here we summarize the mechanistic and clinical data available to guide clinicians in caring for patients with suspected 5-FU cardiotoxicity.

Zebrafish Models of Cancer Therapy-Induced Cardiovascular Toxicity.

Purpose Of Review: Both traditional and novel cancer therapies can cause cardiovascular toxicity in patients. In vivo models integrating both cardiovascular and cancer phenotypes allow for the study of on- and off-target mechanisms of toxicity arising from these agents. The zebrafish is the optimal whole organism model to screen for cardiotoxicity in a high throughput manner, while simultaneously assessing the role of cardiotoxicity pathways on the cancer therapy's antitumor effect.

Perceived and actual fighting ability: determinants of success by decision, knockout or submission in human combat sports.

Animal contest theory assumes individuals to possess accurate information about their own fighting ability or resource-holding potential (RHP) and, under some models, that of their opponent. However, owing to the difficulty of disentangling perceived and actual RHP in animals, how accurately individuals are able to assess RHP remains relatively unknown. Furthermore, it is not just individuals within a fight that evaluate RHP.

The role of spatial accuracy and precision in hermit crab contests.

Understanding the determinants of fighting ability (or resource-holding potential, RHP) is key to elucidating the evolution of aggressive behaviour, as current tests of contest theory rely on realistic proxies for overall RHP. Traditionally, RHP is considered equivalent to body size but it is increasingly clear that a wider range of morphological and physiological traits contribute to fighting ability. In situations analogous to contests, such as courtship displays in animals and competitive sport in humans, the role of skill has long been appreciated but this component has been neglected in analyses of animal fights.

Controlled Solvent Removal from Antiviral Drugs and Excipients in Solution Enables the Formation of Novel Combination Multi-Drug-Motifs in Pharmaceutical Powders Composed of Lopinavir, Ritonavir and Tenofovir.

Diverging physicochemical properties of HIV drug combinations are challenging to formulate as a single dosage form. We have found that 2-to-4 hydrophilic and hydrophobic HIV drugs in combination can be stabilized with lipid excipients under a controlled solvent removal process to form a novel pharmaceutical powder distinct from typical amorphous material. This discovery has enabled production of a drug combination nanoparticle (DcNP) powder composed of 3 HIV drugs-water-insoluble lopinavir (LogP = 4.

Analysis of direct and indirect genetic effects in fighting sea anemones.

Theoretical models of animal contests such as the Hawk-Dove game predict that variation in fighting behavior will persist due to mixed evolutionarily stable strategies (ESS) under certain conditions. However, the genetic basis for this variation is poorly understood and a mixed ESS for fighting can be interpreted in more than one way. Specifically, we do not know whether variation in aggression within a population arises from among-individual differences in fixed strategy (determined by an individual's genotype-direct genetic effects [DGEs]), or from within-individual variation in strategy across contests.

Integration of Computational and Experimental Approaches to Elucidate Mechanisms of First-Pass Lymphatic Drug Sequestration and Long-Acting Pharmacokinetics of the Injectable Triple-HIV Drug Combination TLC-ART 101.

TLC-ART101 is a long-acting triple-HIV drug combination of lopinavir-ritonavir-tenofovir in one nanosuspension intended for subcutaneous injection. After a single TLC-ART 101 administration in nonhuman primates, drug concentrations in both plasma and HIV-target lymph node mononuclear cells were sustained for 2 weeks. Nevertheless, the mechanisms leading to the targeted long-acting pharmacokinetics remain elusive.

Cyp1 Inhibition Prevents Doxorubicin-Induced Cardiomyopathy in a Zebrafish Heart-Failure Model.

Doxorubicin is a highly effective chemotherapy agent used to treat many common malignancies. However, its use is limited by cardiotoxicity, and cumulative doses exponentially increase the risk of heart failure. To identify novel heart failure treatment targets, a zebrafish model of doxorubicin-induced cardiomyopathy was previously established for small-molecule screening.

How does the environment affect fighting? The interaction between extrinsic fighting ability and resource value during contests.

An individual's performance during a fight is influenced by a combination of their capacity and willingness to compete. While willingness to fight is known to be determined by both intrinsic and extrinsic drivers, an individual's capacity to fight is generally thought of as solely intrinsic, being driven by a host of physiological factors. However, evidence indicates that variation in fighting ability can also be generated through exposure to different environmental conditions.

What is a weapon?

Animals utilize an incredible array of traits for offence and defence during conflict. These traits range from exaggerated morphological structures such as the antlers of stags and the horns of beetles, to an arsenal of noxious chemicals emitted, secreted, and injected. However, the breadth of these traits appears to be underappreciated in our current thinking about aggression in animals.

Ions, metabolites, and cells: Water as a reporter of surface conditions during bacterial growth.

Surface-specific nonlinear vibrational spectroscopy, combined with bulk solution measurements and imaging, is used to study the surface conditions during the growth of E. coli. As a result of the silica high surface charge density, the water structure at the silica-aqueous interface is known to be especially sensitive to pH and ionic strength, and surface concentration profiles develop that can be appreciably different from the bulk solution conditions.

Moving the Bariatric Patient.

The health care team must be able to mobilize bariatric patients efficiently and safely. It is challenging to find the proper equipment of sufficient variety to meet the need. Patients can feel self-conscious when staff are struggling to provide care, and staff can be injured when trying to mobilize patients without the proper equipment.

Vaccine hesitancy around the globe: Analysis of three years of WHO/UNICEF Joint Reporting Form data-2015-2017.

In order to gather a global picture of vaccine hesitancy and whether/how it is changing, an analysis was undertaken to review three years of data available as of June 2017 from the WHO/UNICEF Joint Report Form (JRF) to determine the reported rate of vaccine hesitancy across the globe, the cited reasons for hesitancy, if these varied by country income level and/or by WHO region and whether these reasons were based upon an assessment. The reported reasons were classified using the Strategic Advisory Group of Experts (SAGE) on Immunization matrix of hesitancy determinants (www.who.

Long-Acting Profile of 4 Drugs in 1 Anti-HIV Nanosuspension in Nonhuman Primates for 5 Weeks After a Single Subcutaneous Injection.

Daily oral antiretroviral therapy regimens produce limited drug exposure in tissues where residual HIV persists and suffer from poor patient adherence and disparate drug kinetics, which all negatively impact outcomes. To address this, we developed a tissue- and cell-targeted long-acting 4-in-1 nanosuspension composed of lopinavir (LPV), ritonavir, tenofovir (TFV), and lamivudine (3TC). In 4 macaques dosed subcutaneously, drug levels over 5 weeks in plasma, lymph node mononuclear cells (LNMCs), and peripheral blood mononuclear cells (PBMCs) were analyzed by liquid chromatography-tandem mass spectrometry.

Immune function and the decision to deploy weapons during fights in the beadlet anemone, .

The ability to mitigate the costs of engaging in a fight will depend on an individual's physiological state. However, the experience of fighting itself may, in turn, affect an individual's state, especially if the fight results in injury. Previous studies have found a correlation between immune state and fighting success, but the causal direction of this relationship remains unclear.

Cancer clinical trial enrollment of diverse and underserved patients within an urban safety net hospital.

Background: Enrollment rates onto cancer clinical trials are low and reflect a small subset of the population of which even fewer participants come from populations of racial or ethnic diversity or low socioeconomic status. There is a need to increase enrollment onto cancer clinical trials with a focus on recruitment of a diverse, underrepresented patient population.

Objective: To use the electronic medical record (EMR) to understand the eligibility and enrollment rates for all available cancer trials in the ambulatory care setting at an urban safety net hospital to identify specific strategies for enhanced accrual onto cancer clinical trials of diverse and underserved patients.
