Effects of methylphenidate on sensitivity to reinforcement delay, magnitude, and probability: Implications for impulsive and risky choice.

Under rapid-acquisition, concurrent-chains choice procedures, psychomotor stimulants typically decrease the sensitivity of responding to changes in separate dimensions of reinforcement. Across two experiments, pigeons chose between outcomes that differed in terms of reinforcement delay and magnitude (the dimensions involved in delay discounting or "impulsive" choice; Experiment 1) or reinforcement probability and magnitude (the dimensions involved in probability discounting or "risky" choice; Experiment 2). Outcomes associated with each terminal link were varied independently and pseudorandomly across sessions such that in dominated sessions one terminal link was favorable in terms of both dimensions (sooner, larger in Experiment 1 and more likely, larger in Experiment 2) and in trade-off sessions each terminal link was favorable in terms of a different dimension.

A mixed-methods evaluation of an HIV pre-exposure prophylaxis educational intervention for healthcare providers in a NYC safety-net hospital-based obstetrics and gynecology clinic.

Cisgender women and transgender men are less likely to be assessed for PrEP eligibility, prescribed PrEP, or retained in PrEP care. Thus, this pilot PrEP educational intervention was tailored for healthcare providers (HCPs) in obstetrics/gynecology who provide care to cisgender women and transgender men in an academically-affiliated, public hospital women's health clinic. The three-lecture educational curriculum designed for HCPs focused on PrEP eligibility and counseling, formulations and adherence, and prescription and payment assistance programs.

New citizen science initiative enhances flowering onset predictions for fruit trees in Great Britain.

Accurately predicting flowering phenology in fruit tree orchards is crucial for timely pest and pathogen treatments and for the introduction of managed pollinators. Making predictions requires large datasets of flowering dates, which are often limited to single locations. Consequently, the resulting phenology predictions are not representative across larger geographic areas.

Odorant receptors for floral- and plant-derived volatiles in the yellow fever mosquito, Aedes aegypti (Diptera: Culicidae).

Adult mosquitoes require regular sugar meals, including nectar, to survive in natural habitats. Both males and females locate potential sugar sources using sensory proteins called odorant receptors (ORs) activated by plant volatiles to orient toward flowers or honeydew. The yellow fever mosquito, Aedes aegypti (Linnaeus, 1762), possesses a large gene family of ORs, many of which are likely to detect floral odors.

A secondary gendered analysis of interviews with Latina cisgender women indicated for HIV pre-exposure prophylaxis.

HIV infections disproportionately impact Latinx populations in the United States, yet oral pre-exposure prophylaxis (PrEP) uptake is low. This study was a secondary gendered analysis of interviews with Latina cisgender women ( = 20) recruited from an urban safety net hospital inNew York City between August 2019 and October 2022. All women were indicated for PrEP by the provider.

Odorant receptors for floral- and plant-derived volatiles in the yellow fever mosquito, (Diptera: Culicidae).

Adult mosquitoes require regular sugar meals, usually floral nectar, to survive and flourish in natural habitats. Both males and females locate potential sugar sources using sensory proteins called odorant receptors activated by plant volatiles that facilitate orientation toward flowers or honeydew. The Yellow Fever mosquito, (Linnaeus, 1762), possesses a large repertoire of odorant receptors, many of which are likely to support floral odor detection and nectar-seeking.

Serum proteomics reveals APOE dependent and independent protein signatures in Alzheimer's disease.

The current demand for early intervention, prevention, and treatment of late onset Alzheimer's disease (LOAD) warrants deeper understanding of the underlying molecular processes which could contribute to biomarker and drug target discovery. Utilizing high-throughput proteomic measurements in serum from a prospective population-based cohort of older adults (n = 5,294), we identified 303 unique proteins associated with incident LOAD (median follow-up 12.8 years).

Factors associated with loss to follow-up in outpatient parenteral antimicrobial therapy: A retrospective cohort study.

We assessed factors associated with increased risk to loss of follow-up with infectious diseases staff in OPAT patients. Discharge to subacute healthcare facilities is strongly associated with loss to follow-up. We did not identify sociodemographic disparities.

EquiPrEP: An implementation science protocol for promoting equitable access and uptake of long-acting injectable HIV pre-exposure prophylaxis (LAI-PrEP).

Background: Long-acting injectable HIV pre-exposure prophylaxis (LAI-PrEP) was approved by the U.S. Food and Drug Administration in December 2021.

Implementation and early outcomes of a telehealth visit model to deliver tecovirimat for mpox infection in New York City.

The 2022 mpox outbreak in New York City posed challenges to rapidly scaling up treatment capacity. We describe a telehealth treatment model launched during this outbreak that facilitated healthcare provider treatment capacity, and was able to adhere to a Centers for Disease Control and Prevention (CDC)-sponsored expanded access investigational new drug (EA-IND) protocol for tecovirimat. Sixty-nine patients were evaluated and prescribed tecovirimat for mpox through telehealth visits at NYC Health + Hospitals/Bellevue and NYU Langone Health from June to August 2022.

A conserved odorant receptor underpins borneol-mediated repellency in culicine mosquitoes.

The use of essential oils derived from the camphor tree to repel mosquitoes is an ancient practice that originated in Southeast Asia and gradually spread to China and across Europe via the Maritime Silk Road. The olfactory mechanisms by which these oils elicit avoidance behavior are unclear. Here we show that plant bicyclic monoterpenoids and borneol specifically activate a neural pathway that originates in the orphan olfactory receptor neuron of the capitate peg sensillum in the maxillary palp, and projects to the mediodorsal glomerulus 3 in the antennal lobe.

Critical Elements of an Mpox Vaccination Model at the Largest Public Health Hospital System in the United States.

In the spring of 2022, mpox spread to non-endemic countries, including the United States. In New York City (NYC), vaccine demand grew as quickly as case counts. With the leadership of the Regional Emerging Special Pathogens Treatment Center (RESPTC) at NYC Health and Hospitals/Bellevue (NYC H+H)-part of the largest public hospital system in the United States-an innovative vaccination model was established that overcame challenges involving health inequities, inadequate access, and lack of vaccine uptake, to successfully administer JYNNEOS vaccines to over 12,000 patients.

Navigating the expanded access investigational new drug protocol for tecovirimat: lessons learned from a public-private hospital partnership during the 2022 NYC mpox outbreak.

During the 2022 mpox outbreak, tecovirimat was accessed through an expanded access investigational new drug (EA-IND) protocol. We leveraged a unique public/private hospital partnership in New York City to create a novel infrastructure to navigate the EA-IND's regulatory requirements and rapidly provide tecovirimat to patients.

Non-invasive candidate protein signature predicts hepatic venous pressure gradient reduction in cirrhotic patients after sustained virologic response.

Background And Aims: A reduction in hepatic venous pressure gradient (HVPG) is the most accurate marker for assessing the severity of portal hypertension and the effectiveness of intervention treatments. This study aimed to evaluate the prognostic potential of blood-based proteomic biomarkers in predicting HVPG response amongst cirrhotic patients with portal hypertension due to Hepatitis C virus (HCV) and had achieved sustained virologic response (SVR).

Methods: The study comprised 59 patients from two cohorts.

Diols and sugar substitutes in attractive toxic sugar baits targeting Aedes aegypti and Aedes albopictus (Diptera: Culicidae) mosquitoes.

Around the world, mosquitoes continue to transmit disease-causing pathogens and develop resistance to insecticides. We previously discovered that a generally regarded as safe (GRAS) compound, 1,2-propanediol, reduces adult mosquito survivorship when ingested. In this study, we assess and compare 5 more chemically related compounds for mosquito lethality and 8 GRAS sugar substitutes to determine toxicity.

Carboxylic acids that drive mosquito attraction to humans activate ionotropic receptors.

The mosquito, Aedes aegypti, is highly anthropophilic and transmits debilitating arboviruses within human populations and between humans and non-human primates. Female mosquitoes are attracted to sources of blood by responding to odor plumes that are emitted by their preferred hosts. Acidic volatile compounds, including carboxylic acids, represent particularly salient odors driving this attraction.

Behavioral mechanisms of oxycodone's effects in female and male rats: Reinforcement delay and impulsive choice.

μ-Opioid agonists (e.g., morphine) typically increase which has been interpreted as an opioid-induced increase in sensitivity to reinforcement delay.

The Role of a Tertiary Level Safety Net Hospital in New York City's 2022 Mpox Outbreak.

Similar to the early phases of the COVID-19 pandemic, New York City was the national epicenter of the ongoing 2022 mpox (formerly monkeypox) outbreak. Cases quickly began to rise in July 2022, primarily in gay, bisexual, or other men who have sex with men. Tools in the form of a reliable diagnostic test, an effective vaccine, and a viable treatment option have been available from the onset, although logistically complex to roll out.

#COVIDisAirborne: AI-enabled multiscale computational microscopy of delta SARS-CoV-2 in a respiratory aerosol.

We seek to completely revise current models of airborne transmission of respiratory viruses by providing never-before-seen atomic-level views of the SARS-CoV-2 virus within a respiratory aerosol. Our work dramatically extends the capabilities of multiscale computational microscopy to address the significant gaps that exist in current experimental methods, which are limited in their ability to interrogate aerosols at the atomic/molecular level and thus obscure our understanding of airborne transmission. We demonstrate how our integrated data-driven platform provides a new way of exploring the composition, structure, and dynamics of aerosols and aerosolized viruses, while driving simulation method development along several important axes.

Sustaining PrEP Prescriptions at a Safety-Net Hospital in New York City During COVID-19: Lessons Learned.

To understand the impact of COVID-19-related disruptions on PrEP services, we reviewed PrEP prescriptions at NYC Health + Hospitals/Bellevue from July 2019 through July 2021. PrEP prescriptions were examined as PrEP person-equivalents (PrEP PE) in order to account for the variable time of refill duration (i.e.

Functional conservation of Anopheline linalool receptors through 100 million years of evolution.

Insects rely on olfactory receptors to detect and respond to diverse environmental chemical cues. Detection of semiochemicals by these receptors modulates insect behavior and has a direct impact on species fitness. Volatile organic compounds (VOCs) are released by animals and plants and can provide contextual cues that a blood meal host or nectar source is present.
