Wolbachia-infected pharaoh ant colonies have higher egg production, metabolic rate, and worker survival
<p><span><em>Wolbachia</em> is a widespread endosymbiotic bacteria with diverse phenotypic effects on its insect hosts, ranging from parasitic to mutualistic. <em>Wolbachia</em> also commonly infects social insects, where it faces unique challenges associated with its hosts' caste-based reproductive division of labor and colony living. Here we dissect the benefits and costs of <em>Wolbachia</em> infection on life-history traits of the invasive pharaoh ant, <em>Monomorium</em> <em>pharaonis</em>. Pharaoh ants are relatively short-lived and show natural variation in <em>Wolbachia</em> infection between colonies, thereby making them an ideal model system for this study. We quantified effects on the lifespan of queen and worker castes, the egg-laying rate of queens across queen lifespan, and the metabolic rates of whole colonies and colony members. Newly-infected queens laid more eggs than uninfected queens but had similar metabolic rates and lifespans. Surprisingly, infected workers outlived uninfected workers. At the colony level, infected colonies were more productive due to increased queen egg-laying rates and worker longevity, and infected colonies had higher metabolic rates during peak colony productivity. While some effects of infection, such as elevated colony-level metabolic rates may be detrimental in more stressful natural conditions, we did not find any costs of infection under relatively benign laboratory conditions. Overall, our study emphasizes the beneficial effects of <em>Wolbachia</em> on colony-level growth and metabolism in this species.</span></p>
Assessing the prevalence of Female Genital Schistosomiasis and comparing the acceptability and performance of health worker-collected and self-collected cervical-vaginal swabs using PCR testing among women in North-Western Tanzania: the ShWAB study
<p>Female genital schistosomiasis (FGS) is a severe neglected disease, caused by infection with <em>Schistosoma haematobium</em>. The WHO has prioritized the improvement of diagnostics for FGS and previous studies have explored the PCR-based detection of <em>Schistosoma</em> DNA on genital specimens, with encouraging results. We aimed to determine the prevalence of FGS among women living in an endemic district in North-western Tanzania, applying and preliminary comparing self-collected and operator-collected cervical-vaginal swabs followed by PCR, and to assess the acceptability of these sampling procedures.</p>
SARS-CoV-2 vaccine breakthrough infections by Omicron and Delta variants in healthcare workers
<p>An observational prospective cohort study was conducted in vaccinated employees with acute SARS-CoV-2 infection between October 2021 and February 2022. Serological and molecular testing was performed to determine SARS-CoV-2 viral load, lineage, antibody levels, and neutral-ising antibody titres. A total of 571 (9.7%) employees experienced SARS-CoV-2 breakthrough infections during the enrolment period, of which 81 were included. The majority (n=79, 97.5%) was symptomatic and most (n=75, 92.6%) showed Ct-values < 30 in RT-PCR assays. Twenty-four (30%) remained PCR-positive for > 15 days. Neutralizing antibody titres were strongest for the wildtype, intermediate for Delta and lowest for Omicron variants. Omicron infections occurred at higher anti-RBD-IgG serum levels (p= 0.00001) and showed a trend for higher viral loads (p=0.14, median Ct-difference 4.3, 95% CI [-2.5-10.5]). For both variants, viral loads were signifi-cantly higher in participants with lower anti-RBD-IgG serum levels (p=0.02). </p>
Data from: Evaluation of a community health worker home visit intervention to improve child development in South Africa: A cluster-randomized controlled trial
<p><span>This dataset was collected as part of a</span><span> cluster-randomized controlled trial that evaluated the impact of </span>a home visit intervention on child development<span> in Limpopo Province, South Africa. </span><span>Household survey data were collected at baseline and endline. In a subsample of children, neural function was assessed at a lab at endline and at two interim time points. Primary outcomes were: height-for-age z-scores (HAZ) and stunting; child development scores measured using the Malawi Developmental Assessment Tool (MDAT); absolute electroencephalography (EEG) gamma and total power; relative EEG gamma power; and saccadic reaction time (SRT)—</span>an eye-tracking measure of visual processing speed.</p>
Occupational Hazards of Indian Shrimp Farm Workers
<p>The paper reviews a range of global aquaculture health and safety literature to inform and contribute to the development of a socio-economic profile of Indian shrimp farm workers including the occupational hazards and injuries they face. In addition, sixty shrimp farm workers were interviewed from each of the states of Andhra Pradesh, Maharashtra, Gujarat and Tamil Nadu. The study revealed that all shrimp farm workers were male, 58% were migrants, and ages ranged from 23-53 years with work experience of 5-24 years. Few workers (14%) had no formal schooling and many had secondary level education. Reported physical hazards were high (93%) followed by biological (82%), chemical (77%), ergonomic (71%) and psycho-social (71%) hazards. The majority of physical injuries reported related to slips, falls and cuts (51%), electric shocks (44%), sunburn (41%), dehydration/headaches (40%) and fractures (27%). Approximately 30 to 39% had some chemical injury with skin infections/breathing problems. Indian shrimp farm workers face similar occupational hazards and injuries to shrimp farm workers in other countries. The occupational health and safety of shrimp farm workers should be integrated into the concept of ‘One Health’ to ensure aquaculture sustainability and safe, meaningful and good quality employment to workers. </p>
Formica fusca: Queen fecundity, worker entourage, and cuticular chemistry in the ant Formica fusca
<p><span>Cooperative breeding entails conflicts over reproductive shares that may be settled in different ways. In ants, where several queens simultaneously reproduce in a colony, both queens and workers may influence the reproductive apportionment and offspring quality. Queens may vary in their intrinsic fecundity, which may influence the size of the worker entourage attending individual queens, and this may eventually dictate the reproductive output of a queen. We tested whether the reproductive success of queens is affected by the size of their worker entourage, their fecundity at the onset of the reproductive season, and whether the queen cuticular hydrocarbon profile carries information on fecundity. We show that in the ant <em>Formica fusca</em> both queen fecundity and egg hatching success increase with the size of their entourage, and that initially highly fecund queens lay larger eggs. Furthermore, higher relatedness among workers increased queen fecundity. Finally, the queens that received a large worker entourage differed in the cuticular chemistry from those that received a small worker entourage. Our results thus show that workers play a pivotal role in determining queen fitness that high intracolony relatedness among workers enhances the overall reproductive output in the colony, and that queen fecundity is reflected in their cuticular hydrocarbon profile.</span></p>

Violence Against Women in Peru: An Analysis from the Perspective of Workers at Women's Emergency Centers
<p><strong>Objective:</strong> The study aimed to explore and understand the perception and perceived effectiveness of measures implemented to address Violence Against Women (VAW) in the Women's Emergency Centers (CEM in Spanish) in Northern Peru. <strong>Methodology:</strong> A multimethodological approach was adopted, using a descriptive correlational design. 48 CEM workers were included, representing various roles and genders. Data collection was carried out through an online structured questionnaire, validated by experts with a Cronbach's alpha coefficient of 0.7. Analyses encompassed descriptive tests, Spearman correlations, chi<sup>2</sup>, and multiple regressions, using SPSS and Jamovi statistical software. <strong>Results:</strong> It was identified that physical violence was statistically higher than psychological violence, and the latter was higher than sexual violence. Additionally, a significant relationship was evidenced between the perception of violence and the perceived effectiveness of the measures implemented in the CEM. <strong>Conclusion:</strong> The perception of VAW in the CEM of Northern Peru is multifaceted, with physical violence being the most prevalent. Although there is a perceived moderate effectiveness of existing measures, it is essential to consider contextual and cultural factors in future interventions and studies. Recommendations include strengthening prevention and care strategies, as well as promoting greater community awareness of the various forms of VAW.</p>
