Exploiting human immune repertoire transgenic mice for protective monoclonal antibodies against antimicrobial resistant Acinetobacter baumannii.

The use of monoclonal antibodies for the control of drug resistant nosocomial bacteria may alleviate a reliance on broad spectrum antimicrobials for treatment of infection. We identify monoclonal antibodies that may prevent infection caused by carbapenem resistant Acinetobacter baumannii. We use human immune repertoire mice (Kymouse platform mice) as a surrogate for human B cell interrogation to establish an unbiased strategy to probe the antibody-accessible target landscape of clinically relevant A.

Testing the evolutionary drivers of malaria parasite rhythms and their consequences for host-parasite interactions.

Undertaking certain activities at the time of day that maximises fitness is assumed to explain the evolution of circadian clocks. Organisms often use daily environmental cues such as light and food availability to set the timing of their clocks. These cues may be the environmental rhythms that ultimately determine fitness, act as proxies for the timing of less tractable ultimate drivers, or are used simply to maintain internal synchrony.

Combining machine learning with high-content imaging to infer ciprofloxacin susceptibility in isolates of Salmonella Typhimurium.

Antimicrobial resistance (AMR) is a growing public health crisis that requires innovative solutions. Current susceptibility testing approaches limit our ability to rapidly distinguish between antimicrobial-susceptible and -resistant organisms. Salmonella Typhimurium (S.

Virulence is associated with daily rhythms in the within-host replication of the malaria parasite .

Most malaria ( spp.) parasite species undergo asexual replication synchronously within the red blood cells of their vertebrate host. Rhythmicity in this intraerythrocytic developmental cycle (IDC) enables parasites to maximise exploitation of the host and align transmission activities with the time of day that mosquito vectors blood feed.

Exploring attitudes and variation by sociodemographic factors in consent provided for financial data linkage in an experimental birth cohort study.

Background: Improving our understanding of household incomes and what constitutes financial insecurity can help us to better understand how financial insecurity is experienced and how this can change over time within and between individuals and populations. However, financial circumstances are often perceived as sensitive and stigmatising, particularly within some ethnic minority groups. This research aims to explore attitudes and variation by sociodemographic factors in consent provided for financial data linkage in an experimental birth cohort study, in order to obtain validated income and benefits data and to better understand the impact of community interventions on the financial security of its participants and their families.

Toward a molecular microbial blood test for tuberculosis infection.

The World Health Organization's aim to end the global tuberculosis (TB) epidemic by 2050 cannot be achieved without taking measures to identify people with asymptomatic Mycobacterium tuberculosis (Mtb) infection and offer them an intervention to reduce the risk of disease progression, such as preventive antimicrobial therapy. Implementation of this strategy is limited by the fact that existing tests for Mtb infection, which use immunosensitization to Mtb-specific antigens as a proxy for infection, have low positive predictive value for progression to TB. A blood test that detects Mtb deoxyribonucleic acid (DNA) could allow preventive therapy to be targeted at individuals with microbiological evidence of persistent infection.

Exploring the feasibility of evaluating a community alliance welfare advice programme co-located in primary care in Bradford: an uncontrolled before and after study.

Background: Welfare advice services co-located in health settings are known to improve financial security. However, little is known on how to effectively evaluate these services. This study aims to explore the feasibility of evaluating a welfare advice service co-located in a primary care setting in a deprived and ethnically diverse population.

Machine learning reveals singing rhythms of male Pacific field crickets are clock controlled.

Circadian rhythms are ubiquitous in nature and endogenous circadian clocks drive the daily expression of many fitness-related behaviors. However, little is known about whether such traits are targets of selection imposed by natural enemies. In Hawaiian populations of the nocturnally active Pacific field cricket (, males sing to attract mates, yet sexually selected singing rhythms are also subject to natural selection from the acoustically orienting and deadly parasitoid fly, .

Association of the COVID-19 Pandemic With Women, Infants, and Children (WIC) Receipt Among Pregnant Individuals: United States, 2016-2022.

To evaluate the effect of COVID-19 on Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) receipt among pregnant individuals overall and by race/ethnicity. We measured changes in WIC receipt among Medicaid-covered births (n = 10 484 697) from the US National Center for Health Statistics Natality Files (2016-2022). Our interrupted time series logistic model included a continuous monthly variable, a binary post-COVID variable, and a continuous slope shift variable.

The long-term impact of the Covid-19 pandemic on financial insecurity in vulnerable families: Findings from the Born in Bradford Covid-19 longitudinal study.

There is growing recognition that the public health measures employed to control the spread of the COVID-19 pandemic had unintended consequences on socioeconomic security and health inequalities, having the greatest impact on the most vulnerable groups. This longitudinal study aims to explore the medium to long-term impacts of the COVID-19 pandemic and subsequent public health measures on financial security for families living in the deprived and ethnically diverse city of Bradford. We collected data at four time points before and during the pandemic from mothers who participated in one of two prospective birth cohort studies in Bradford.

Hesitant adopters: COVID-19 vaccine hesitancy among diverse vaccinated adults in the United States.

Background: Despite the United States (US) having an abundant supply of COVID-19 vaccines, vaccination rates lag behind other high-income countries, suggesting that vaccine hesitancy and attitudes play a greater role in public health measures than pure supply and access. With the acknowledgment that vaccination attitudes and status may or may not be correlated, this study examined COVID-19 vaccine hesitancy among vaccinated US adults by asking: 1) What is the prevalence of COVID-19 vaccine hesitancy among the vaccinated? 2) Does COVID-19 vaccine hesitancy vary across sociodemographic characteristics? 3) Does COVID-19 vaccine hesitancy vary by healthcare access and influenza vaccination over the past 5 years?

Methods: Data were collected through an online survey of 2022 US adults with a final analytic sample of 1383 vaccinated respondents.

Results: Overall, 48.

Testing a non-destructive assay to track Plasmodium sporozoites in mosquitoes over time.

Background: The extrinsic incubation period (EIP), defined as the time it takes for malaria parasites in a mosquito to become infectious to a vertebrate host, is one of the most influential parameters for malaria transmission but remains poorly understood. The EIP is usually estimated by quantifying salivary gland sporozoites in subsets of mosquitoes, which requires terminal sampling. However, assays that allow repeated sampling of individual mosquitoes over time could provide better resolution of the EIP.

Global database of cement production assets and upstream suppliers.

Cement producers and their investors are navigating evolving risks and opportunities as the sector's climate and sustainability implications become more prominent. While many companies now disclose greenhouse gas emissions, the majority from carbon-intensive industries appear to delegate emissions to less efficient suppliers. Recognizing this, we underscore the necessity for a globally consolidated asset-level dataset, which acknowledges production inputs provenance.

Correlates of COVID-19 vaccine coverage in Arkansas: Results from a weighted random sample survey.

We assessed COVID-19 vaccination (≥1 dose) status as influenced by sociodemographic factors (i.e., age, gender, race/ethnicity, education, income, and parent or guardian status), healthcare provider recommendation, and personal vaccine hesitancy among Arkansas residents in October 2022.

The impact of innate immunity on malaria parasite infection dynamics in rodent models.

Decades of research have probed the molecular and cellular mechanisms that control the immune response to malaria. Yet many studies offer conflicting results on the functional impact of innate immunity for controlling parasite replication early in infection. We conduct a meta-analysis to seek consensus on the effect of innate immunity on parasite replication, examining three different species of rodent malaria parasite.

Social processes, practical issues, and COVID-19 vaccination among hesitant adults.

Introduction: The purpose of this study is to examine relationships between COVID-19 vaccination, social processes, and the practical issues of healthcare coverage and workplace requirements. We examine these relationships among individuals who expressed some degree of hesitancy towards receiving the vaccine. Assessing relationships between COVID-19 vaccination, social processes, and practical issues among vaccine-hesitant individuals has implications for public health policy and intervention.

Exploring the feasibility, acceptability, and preliminary effectiveness of a culturally adapted group prenatal program, CenteringPregnancy, to reduce maternal and infant health disparities among Marshallese Pacific Islanders: A study protocol.

Background: Marshallese Pacific Islanders residing in the United States have higher rates of adverse perinatal outcomes than the general population and experience numerous barriers to prenatal care. CenteringPregnancy is a group prenatal care model which occurs in the patient's community. CenteringPregnancy, when applied to the Marshallese population, presents a potentially highly successful group-based intervention that can mitigate adverse perinatal outcomes among Marshallese Pacific Islanders.

An Avatar-Led Web-Based and SMS Text Message Smoking Cessation Program for Socioeconomically Disadvantaged Veterans: Pilot Randomized Controlled Trial.

Background: Despite the declining prevalence of cigarette smoking in the United States, socioeconomically disadvantaged veterans receiving care from the Veterans Health Administration have a high prevalence of smoking. Currently, available treatment options for these veterans focus on tobacco users who are ready to quit and have limited reach. Consequently, there is a great need for accessible, effective smoking cessation interventions for veterans at all levels of readiness to quit smoking.

Application Status Among Women Enrolled in a Healthy Start Program in Arkansas for the Special Nutrition Program for Women and Children.

This study aimed to examine the demographic characteristics of pregnant women in a Healthy Start program who are presumed eligible for the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), but who have not yet applied for WIC benefits. We used a cross sectional evaluation of data collected from pregnant women (n=203) participating in a Healthy Start program. Data came from surveys administered at enrollment in the Healthy Start program from July 15th, 2019 until January 14th, 2022.

Determinants of QuantiFERON Plus-diagnosed tuberculosis infection in adult Ugandan TB contacts: A cross-sectional study.

Background: The tuberculin skin test is commonly used to diagnose latent tuberculosis infection (LTBI) in resource-limited settings, but its specificity is limited by factors including cross-reactivity with BCG vaccine and environmental mycobacteria. Interferon-gamma release assays (IGRA) overcome this problem by detecting M. tuberculosis complex-specific responses, but studies to determine risk factors for IGRA-positivity in high TB burden settings are lacking.

Clinical and laboratory factors associated with neonatal sepsis mortality at a major Vietnamese children's hospital.

Sepsis is a major cause of neonatal mortality and children born in low- and middle-income countries (LMICs) are at greater risk of severe neonatal infections than those in higher-income countries. Despite this disparity, there are limited contemporaneous data linking the clinical features of neonatal sepsis with outcome in LMICs. Here, we aimed to identify factors associated with mortality from neonatal sepsis in Vietnam.
