Nutrient availability in a freshwater-to-marine continuum: Cyanobacterial blooms along the Lake Okeechobee Waterway.

Water from the Lake Okeechobee watershed historically flowed south through the Everglades. Hydrologic alterations created the Lake Okeechobee Waterway, where lake water is periodically shunted east to the St. Lucie Estuary (C-44 canal) and west to the Caloosahatchee River and Estuary (C-43 canal).

Emerging evidence for pregnane steroid therapeutics for alcohol use disorders.

Many lines of research have suggested that the neuroactive pregnane steroids, including pregnenolone, progesterone, and allopregnanolone ([3α,5α]-3-hydroxypregnan-20-one, 3α,5α-THP), have therapeutic potential for treatment of alcohol use disorders (AUDs). In this chapter, we systematically address the preclinical and clinical evidence that supports this approach for AUD treatment, describe the underlying neurobiology of AUDs that are targeted by these treatments, and delineate how pregnane steroids may address various components of the disease. This review updates the theoretical framework for understanding how endogenous steroids that modulate the effects of alcohol, stress, excitatory/inhibitory and dopamine transmission, and the innate immune system appear to play a key role in the prevention and mitigation of AUDs.

VCP/p97-associated proteins are binders and debranching enzymes of K48-K63-branched ubiquitin chains.

Branched ubiquitin (Ub) chains constitute a sizable fraction of Ub polymers in human cells. Despite their abundance, our understanding of branched Ub function in cell signaling has been stunted by the absence of accessible methods and tools. Here we identify cellular branched-chain-specific binding proteins and devise approaches to probe K48-K63-branched Ub function.

Incorporating social determinants of health into transmission modeling of COVID-19 vaccine in the US: a scoping review.

Unlabelled: During COVID-19 in the US, social determinants of health (SDH) have driven health disparities. However, the use of SDH in COVID-19 vaccine modeling is unclear. This review aimed to summarize the current landscape of incorporating SDH into COVID-19 vaccine transmission modeling in the US.

Neuroactive Steroids, Toll-like Receptors, and Neuroimmune Regulation: Insights into Their Impact on Neuropsychiatric Disorders.

Pregnane neuroactive steroids, notably allopregnanolone and pregnenolone, exhibit efficacy in mitigating inflammatory signals triggered by toll-like receptor (TLR) activation, thus attenuating the production of inflammatory factors. Clinical studies highlight their therapeutic potential, particularly in conditions like postpartum depression (PPD), where the FDA-approved compound brexanolone, an intravenous formulation of allopregnanolone, effectively suppresses TLR-mediated inflammatory pathways, predicting symptom improvement. Additionally, pregnane neurosteroids exhibit trophic and anti-inflammatory properties, stimulating the production of vital trophic proteins and anti-inflammatory factors.

Caregiver Experience with Bicultural, Bilingual Family Navigators to Support Early Childhood Development.

Recognizing the inequities in developmental screening and services for children in immigrant families, a pediatric primary care clinic in partnership with a community-based early childhood program co-created a bicultural, bilingual early childhood developmental (ECD) family navigator program in Seattle, Washington. The primary aim of this study is to explore caregivers' perspectives about this program. Twenty-seven caregivers of young children participated in semi-structured interviews that were thematically analyzed.

Effectiveness of atropine in managing sialorrhea: A systematic review and meta-analysis.

Objectives: To describe the efficacy of atropine in controlling salivary flow in patients with sialorrhea or drooling.

Materials And Methods: We included randomized controlled studies, quasi-randomized trials, case reports, clinical trials, systematic reviews, and meta-analyses assessing the use of atropine in patients with sialorrhea or drooling. The endpoints were reduction in salivary flow rate, amount of saliva secreted, reduction in clinical symptoms of sialorrhea, death rattle intensity, or reduction in drooling intensity as measured by an objective scale such as the drooling intensity scale.

Quality improvement approaches to heparin-induced thrombocytopenia: a scoping review.

Background: Heparin-induced thrombocytopenia (HIT) is a relatively uncommon condition characterized by 2 exceedingly common phenomena in hospitalized patients: thrombocytopenia and heparin exposure. Consequently, HIT is frequently overdiagnosed and inappropriately treated. These issues are the focus of many quality improvement (QI) initiatives.

An Assessment of Potential Threats to Human Health from Algae Blooms in the Indian River Lagoon (USA) 2018-2021: Unique Patterns of Cytotoxicity Associated with Toxins.

The Indian River Lagoon (IRL), a 156-mile-long estuary located on the eastern coast of Florida, experiences phytoplankton bloom events due to increased seasonal temperatures coupled with anthropogenic impacts. This study aimed to gather data on the toxicity to human cells and to identify secondary metabolites found in water samples collected in the IRL. Water samples from 20 sites of the IRL were collected during the wet and dry seasons over a three-year period.

Symptom frequency and exposure to a cyanobacteria bloom in Florida.

This investigation was undertaken to characterize health effects associated with a major bloom of blue-green algae due to the proliferation Microcystis aeruginosa that occurred in Florida in 2018. Cyanobacteria produce multiple toxins, including the potent hepatotoxic microcystins (MCs), that have been reported to cause illness in exposed persons worldwide. Widespread exposure to toxins released by blue-green algae during the 2018 bloom was shown by the presence of MCs in the nasal passages of 95 percent of the individuals studied previously in south Florida (Schaefer et al.

Deleterious Interaction between the Neurosteroid (3α,5α)3-Hydroxypregnan-20-One (3α,5α-THP) and the Mu-Opioid System Activation during Forced Swim Stress in Rats.

The neurosteroid 3α,5α-THP is a potent GABA receptor-positive modulator and its regulatory action on the HPA axis stress response has been reported in numerous preclinical and clinical studies. We previously demonstrated that 3α,5α-THP down-regulation of HPA axis activity during stress is sex-, brain region- and stressor-dependent. In this study, we observed a deleterious submersion behavior in response to 3α,5α-THP (15 mg/kg) during forced swim stress (FSS) that led us to investigate how 3α,5α-THP might affect behavioral coping strategies engaged in by the animal.

Racial Slurs by Police and Posttraumatic Stress Symptoms: Intrusive Policing and Perceived Injustice.

Using the Future of Families and Child Wellbeing Study (N = 785), this article considers the ramifications of police use of racial slurs, a type of intrusive behavior, toward minority youth for posttraumatic stress (PTS). We also examine whether other intrusive police behaviors exacerbate this relationship and test whether perceptions of injustice mediate it. Results indicated that hearing a police officer use a racial slur was positively associated with PTS after controlling for intrusive police behaviors and other covariates.
