An animal’s diet breadth is a central aspect of its life history, yet the factors determining why some species have narrow dietary breadths (specialists) and others have broad dietary breadths (generalists) remain poorly understood. This challenge is pronounced in herbivorous insects due to incomplete host plant data across many taxa and regions. Here, we develop and validate machine learning models to predict pollen diet breadth in bees, using a bee phylogeny and occurrence data for 682 bee species native to the United States, aiming to better understand key drivers. We found that pollen specialist bees made an average of 72.9% of their visits to host plants and could be predicted with high accuracy (mean 94%). Our models predicted generalist bee species, which made up a minority of the species in our dataset, with lower accuracy (mean 70%). The models tested on spatially and phylogenetically blocked data revealed that the most informative predictors of diet breadth are plant phylogenetic diversity, bee species’ geographic range, and regional abundance. Our findings also confirm that range size is predictive of diet breadth and that both male and female specialist bees mostly visit their host plants. Overall, our results suggest we can use visitation data to predict specialist bee species in regions and for taxonomic groups where diet breadth is unknown, though predicting generalists may be more challenging. These methods can thus enhance our understanding of plant-pollinator interactions, leading to improved conservation outcomes and a better understanding of the pollination services bees provide.

Background The freelance economy has seen rapid growth worldwide in recent years and the Philippines is not an exception. Freelance workers are becoming increasingly common in healthcare and research. Early career researchers carry out most of scientific research and can play a critical role in advancing public health by bringing new perspectives and diversity to the field. Existing literature has mostly focused on the experiences of early career researchers in an institutional academic setting. This study aimed to understand the experiences of freelance early career researchers in the health policy and systems space in the Philippines. Methods This qualitative study collected data from 18 to 22 March 2022 through virtual interview and focus group discussions. Themes and codes were created based on the topic guide developed. New themes and codes were generated as they emerged. Two researchers coded the data using both a priori and emergent codes. Any coding conflicts were resolved through discussions until intercoder agreement was reached. Interpretation and conclusions from the data were developed by 2 researchers with consideration for its context and relationship between themes. Results Fifteen current and former freelance researchers participated in the study. Most are female, under 35 years old, and with an undergraduate degree as the highest educational attainment. The findings highlight insights and challenges faced by early career researchers in aspects of: (1) work arrangement, (2) tasks, (3) expectations from senior researchers, (4) development in the health policy and systems field, (5) relationship with peers, and (6) motivations for continuing to work as a freelance health policy and systems researcher. Conclusion This study reveals the challenges freelance early career researchers face, highlighting the need for enhanced support and recognition amidst rapidly evolving workforce demands and complex health dilemmas. Recommendations include structured mentorship, professional development, innovative funding models, and the establishment of a supportive network. Advocacy for policies ensuring freelancer inclusion in the economy and policy-making is crucial. Future research should investigate their experiences further, including their roles, transitions, and the impacts of funding trends, to foster their development and integration into public health research and policy.

[...]in Part I, this comment will consider the problems mental illness poses for American Indians before demonstrating that the legislature, the courts, and the federal government must take action to minimize the troubling effects posed by native communities' lacking mental health care infrastructure. [...]Part IV will suggest possible approaches for improving mental health care for American Indians and using the current statutes to aid American Indian communities in their mental health needs, along with a proposed revision to the statutory scheme to provide for more effective implementation and enforcement. Mental Illness Prevalence and Severity American Indians suffer from most mental disorders in rates similar to the population of the entire United States, despite the fact that recent research indicates that native populations experience much more psychological distress.12 Furthermore, Indians suffer from certain disorders at a higher rate than the population does generally, for example, American Indian populations have extremely high rates of suicide, unemployment, and poverty.13 These problems also place native populations at greater risk for certain mental health disorders14 than the general population.15 Specifically, American Indians suffer significantly from anxiety, posttraumatic stress disorder (PTSD), substance abuse, and depression.16 In the general population of the United States, about one in four adults will experience mental illness in any given year.17 Suicide, in particular, is the tenth leading cause of death, though it ranks third for individuals between the ages fifteen and twenty-four years old.18 Among American Indian populations, however, the numbers are even more alarming. \"36 Though the percent of health care providers offering actual mental health care services is lower by number, there are constant efforts to strengthen this number in an attempt to better provide for the nation's population.37 For example, in 2012 and 2013, a \"Behavioral Health Integration Learning Community\" was started in an effort to address the needs of health care centers that were not yet providing mental health care services. 38 The Administration is placing extra emphasis on the integration of mental health into the facilities and systems lacking mental health care options.39 In addition, in the United States

The aim of the study was to assess the factors associated with mother-to-child transmission (MTCT) of HIV. The study design is a retrospective cohort. The population consisted of 323 HIV-positive mothers and their newborns, attended at the Perinatal Nucleus/HUPE-UERJ, municipality of Rio de Janeiro, in the period of 2007-2018. The average age of mothers was 27 years (14-44), with 12.7% (41) of adolescents. The majority (66.8%) knew they were infected during pregnancy: 39.4% in the current pregnancy and 27.4% in a previous pregnancy. The incidence of MTCT was 2.7% in 2007-2009, 1% in 2010-2015 and 0 in 2016-2018. The viral load in the 3rd trimester of pregnancy was > 1.000 copies/mL or unknown in all mothers with positive newborns and in 19% (42/221) of mothers with negative newborns (p=0.003). The duration of antiretroviral use was > 4 weeks in 92.3% (264/286) of mothers with HIV-negative newborns and in 2 in the HIV-positive group (p=0.004). One of the 4 infected newborns and 2 of the negative ones did not use oral zidovudine (p=0.04). There was no association between amniorrhexis and MTCT (p=0.99), with the Apgar score in the 5th minute of life (p=0.96), with marital status (p=0.54), ethnicity (p=0.65), adolescence (p=0.42), mode of delivery (p=0.99), beginning of prenatal care (p=0.44) or with maternal comorbidities (p=0.48). The conclusion of the study points out that the main factors associated with MTCT are the elevated maternal viral load in the 3rd trimester, the time of use of ART and the non-administration of zidovudine for the newborns.The aim of the study was to assess the factors associated with mother-to-child transmission (MTCT) of HIV.

This project examines the effect of family separation on people who have loved ones incarcerated in California state prisons. Using survey data collected by Initiate Justice, a Los Angeles-basedcommunity organization that seeks to end mass incarceration by harnessing the power of those “inside,” my research examines barriers to accessing those loved ones and asks, “What is the effect of family separation on loved ones left behind?” I frame my research with an abolitionist lens and incorporate the theory of racial capitalism in my study. My research views incarcerated people as important family and community members and finds that their absence from these spaces impacts their families and communities negatively. Combining qualitative and quantitative survey analysis with a review of the literature, I offer a vision of a system that does not need police and prisons, and prioritizes health and healing as community priorities, instead.

Modifying food texture is an important part of dysphagia management, yet less is known about the day-to-day practices that might impact the nutritional well-being of patients. This study surveyed staff involved in the service delivery of texture-modified foods with the objectives to gain information about roles and responsibilities, instruction and knowledge about modifying foods, and beliefs about the use of texture-modified foods in nutrition care. We created a 21-item survey about texture-modified foods. Recruitment efforts focused on both professional and frontline staff involved in service delivery. Practice groups and organizations provided the means of recruiting professionals from different disciplines. Because frontline staff (e.g., certified nursing assistants, cooks) do not have similar membership groups, we recruited them through direct contacts with health care agencies. A total of 175 individuals completed the survey. Respondents included 107 professionals (primarily certified dietary managers, registered dietitians, speech-language pathologists) and 68 frontline staff (mostly certified nursing assistants/home health aides). Although the frontline and professional staff showed generally similar patterns of opinions and beliefs about modified food textures, differences emerged in reported experiences, roles, and responsibilities in service delivery. Survey respondents conveyed generally positive attitudes and opinions about the use of texture-modified foods, and respondents perceived them to be easy to execute and beneficial to the nutritional well-being of patients. Survey findings clearly highlight the contributions of frontline staff in the service delivery of modified food textures. Consideration must be given to continued reliance on informal, limited instruction about texture-modified foods and possible implications for safe nutrition care. Both professional and frontline staff convey a willingness to customize or alter food textures and the belief that patients should be able to choose the level of texture modification that they want to eat.
