Per- and polyfluoroalkyl substances (PFAS) pose a significant health threat due to their environmental persistence and toxicity. While PFAS contamination is widespread in Florida, the state currently lacks fish consumption advisories (FCAs) for these compounds, despite existing FCAs for legacy pollutants. This study quantified 40 PFAS in edible muscle tissue from 264 fish (16 species) across four estuaries along Florida's Atlantic coast to assess ecological and human health risks. The highest concentrations of total PFAS were found in Red Drum (Sciaenops ocellatus; 0.209 - 51.6ng/g wet weight) and Spotted Seatrout (Cynoscion nebulosus; 2.01 - 24.3ng/g ww) in the Indian River Lagoon, where up to 68% of Red Drum and 75% of Spotted Seatrout exceeded ecological quality standards, indicating potential impacts on predators. PFOS was the predominant PFAS, driving ecological and human health risks. Estimated daily intakes (EDIs) of PFOS exceeded the EPA reference dose (RfD) by up to 3 orders of magnitude, with the highest exposures concentrated in Red Drum and Spotted Seatrout from the Indian River Lagoon. These findings highlight that PFAS monitoring of tissue concentrations in fish across Florida's freshwater and marine systems would be needed for accurately quantifying exposure risks. Such efforts are fundamental to informing regulatory frameworks regarding FCAs and ensuring the long-term protection of aquatic ecosystems and human health.

Objectives. To examine how socioeconomic status (SES) shaped intraracial health disparities among Black women before, during, and after the COVID-19 pandemic. Methods. Using Behavioral Risk Factor Surveillance System data (2018-2023; n = 89 634 Black women), we analyzed temporal trends in self-rated health, days of poor physical and mental health, and SES (education, income, employment). Results. Educational disparities in self-rated health temporarily compressed during the pandemic (health disparity decreased by 3.9%) before partially reexpanding after the pandemic. Income-based physical health disparities persisted: the lowest-income women reported 7.48 poor physical health days before the pandemic versus 2.38 days for highest-income peers. Mental health decreased universally, with lowest-income women reporting 7.00 poor mental health days per year after the pandemic versus 6.09 days before the pandemic. Unemployed women experienced temporary pandemic-period health improvements (b = -2.07; P = .05) Conclusions. Although the pandemic temporarily compressed educational disparities, income and employment-based inequities persisted or widened, underscoring SES as a partial buffer and site of structural health inequality. Public Health Implications. Sustaining pandemic-era protections (expanded health care, income supports) and prioritizing mental health equity are critical to addressing systemic inequities exacerbated by crises.

Circadian rhythms are key determinants of physical and mental health at the nexus of physiology and behavior. Classically, endogenous circadian rhythms are characterized according to three principal dimensions: circadian phase, amplitude and stability. From a behavioral perspective, the timing and regularity of nychthemeral behaviors represent two additional dimensions, and we propose as a sixth dimension the sleep complaints arising from a circadian disruption due to a mismatch between circadian physiology and nycthemeral behaviors. This article reviews each of these dimensions and examines their interactions, along with their effects on sleep and health. On this basis, we propose an integrated definition of circadian health. We then review both, objective (melatonin, temperature, actimetry) and subjective (sleep diaries, self-report questionnaires) tools for assessing each of the circadian health dimensions. Finally, we propose a novel tool aimed at assessing those circadian health dimensions as well as the computation of a composite index to quantify circadian health, along with a graphical representation to visualize it. While further validation is still needed, this proposal will help clinicians and researchers better decipher circadian rhythms and their impact on mental and physical health and may offer new opportunities for public health promotion in both general and clinical populations.

Identifying the optimal predictors for adolescent mental and physical health using machine learning methods.

To advance patient-centered care for high-need homeless-experienced patients, we identified the rates of various personal health goals, the broader domains that underlie these goals, and associations between these domains and the health-related needs of this population. The sample consisted of 176 veterans from 3 VA Medical Centers who were enrolled in primary care, on VA's Homeless Registry, and high utilizers of acute care. An interview was conducted with each participant to collect information on their personal health goals and health-related needs. Exploratory factor analysis was used to identify broad domains underlying endorsement of personal health goals. Associations between these broad goal domains and health-related needs (substance use, mental and physical health, treatment engagement, and psychosocial) were examined using an exploratory structural equation modeling-within-confirmatory factor analysis approach. Three broad domains were found to underlie the personal health goals of the sample: social functioning, health promotion, and substance use. Social functioning and health promotion were highly correlated, whereas substance use was weakly correlated with both social functioning and health promotion. All substance use-related needs were positively associated with substance use goals. Mental and physical health needs were primarily associated with health promotion goals. Treatment engagement and psychosocial needs demonstrated associations across all 3 goal domains. Findings highlight the high value that many high-need homeless-experienced patients place on their social well-being and the potential benefits to measuring both deficiency and growth needs in this population. Clinical implications and future directions for research are discussed.

Divulging the hidden risks of trace and heavy elements in sports nutritional supplements; a comprehensive study targeted with health risk evaluation.

Sauna culture is experiencing rapid global growth, yet beyond physical health benefits, remains largely understudied within academic research. We investigate both its physical and mental health benefits in the UK using the Social Cure model in conjunction with a ritual lens to understand how feelings of connection grow via sauna. Across three studies (N = 1,907), we explored the role of social identities in shaping wellbeing outcomes among sauna users. Studies 1 and 3 employed longitudinal designs, revealing increases in emotional wellbeing over time, while Study 2 used a cross-sectional approach and showed that stronger sauna identities were associated with self-reported improvements in both physical and emotional wellbeing. Study 3 further demonstrated that perceiving sauna use as a ritual, alongside experiencing emotional synchrony during sauna sessions, was positively linked to stronger sauna identities. Together, these findings suggest that the social and ritual aspects of sauna use may contribute to its wellbeing effects, with potential implications for sauna operators in the UK and beyond.

Harmful cyanobacterial blooms pose increasing threats to aquatic ecosystems and human health; yet, the role of zooplankton grazing in regulating blooms remains understudied. We investigated the seasonal feeding behaviour and fitness consequences of feeding preferences in natural zooplankton communities for toxic (microcystin-producing) versus non-toxic cyanobacteria across temperature gradients in eutrophic Lake Greifen, Switzerland. We conducted monthly experiments from April to October 2023 to test the grazing behaviour of four zooplankton groups (daphnids, calanoid copepods, cyclopoid copepods, and microzooplankton) exposed to mixed diets of green algae and either toxic or non-toxic Microcystis strains at 15 °C and 25 °C. Contrary to expectations of cyanobacteria avoidance, zooplankton exhibited predominantly non-selective grazing throughout the seasonal succession, consuming both toxic and non-toxic cyanobacteria at similar rates, regardless of temperature. Notably, during the peaks of phytoplankton abundance (April and September), mesozooplankton demonstrated a selective preference for cyanobacteria over green algae, particularly non-toxic strains. Temperature effects were subtle but revealed metabolic constraints: elevated temperatures occasionally triggered selective consumption of cyanobacteria in copepods, while fitness costs (survival) from exposure to toxic species were mostly restricted to transitional bloom periods and high-temperature conditions. These findings suggest that toxic cyanobacteria may not always evade grazing pressure through secondary metabolite deterrent effects. Our results suggest that zooplankton communities can adapt and graze on cyanobacteria regardless of toxicity under the tested conditions, even during bloom conditions. These observations highlight the potential for zooplankton to interact with cyanobacterial populations, which may have implications for bloom prediction and management strategies, particularly under climate warming scenarios.
