Fluoride Exposure and Children's IQ Scores: A Systematic Review and Meta-Analysis.

Importance: Previous meta-analyses suggest that fluoride exposure is adversely associated with children's IQ scores. An individual's total fluoride exposure comes primarily from fluoride in drinking water, food, and beverages.

Objective: To perform a systematic review and meta-analysis of epidemiological studies investigating children's IQ scores and prenatal or postnatal fluoride exposure.

Priority Clinical Actions for Outpatient Management of Nonhospitalized Traumatic Brain Injury.

Outpatient care following nonhospitalized traumatic brain injury (TBI) is variable, and often sparse. The National Academies of Sciences, Engineering, and Medicine's 2022 report on highlighted the need to improve the consistency and quality of TBI care in the community. In response, the present study aimed to identify existing evidence-based guidance and specific clinical actions over the days to months following nonhospitalized TBI that should be prioritized for implementation in primary care.

Oxytocin versus carbetocin at elective Cesarean delivery in parturients with class III obesity: a double-blind randomized controlled noninferiority trial.

Purpose: Class III obesity (body mass index [BMI] ≥ 40 kg·m) is associated with high rates of Cesarean deliveries and postpartum hemorrhage, with increased maternal and fetal morbidity. The doses of oxytocin and carbetocin are two to four times higher at Cesarean delivery in patients with class III obesity. We sought to investigate the efficacy of carbetocin 80 µg iv compared with oxytocin 1 IU iv (plus infusion) at elective Cesarean delivery in parturients with class III obesity.

Incarceration is associated with higher mortality after trauma: An unreported health care disparity.

Background: While the United States has the highest incarceration rate worldwide, at nearly 1% of the adult population (more than 2 million people), insights regarding health disparities in this population remain limited. This retrospective cohort study represents the largest national database analysis of incarcerated trauma patients to date and investigates whether incarceration status is an independent risk factor for poor outcomes after trauma for US adults.

Methods: We analyzed data from the National Trauma Data Bank from 2017 to 2018.

Students' Reports of Challenges, Experiences, and Perceptions of Equity, Diversity, and Inclusion at Veterinary Colleges in Canada and the United States.

Equity, diversity, and inclusion (EDI) in veterinary medicine affects veterinarians, students, clients, and the regional availability of veterinary services. Veterinary students from 5 colleges in Canada and 5 colleges in the United States were surveyed about their challenges, experiences, and perceptions related to EDI, resulting in 456 responses (10.4%).

A unified neurocomputational model of prospective and retrospective timing.

Time is a central dimension against which perception, action, and cognition play out. From anticipating when future events will happen to recalling how long ago previous events occurred, humans and animals are exquisitely sensitive to temporal structure. Empirical evidence seems to suggest that estimating time prospectively (i.

Redundant voicing and register in Mnong Râlâm.

Mnong Râlâm is a South Bahnaric language (Austroasiatic) that is traditionally described as preserving a voicing contrast in onset obstruents, contrary to other languages of the Mnong/Phnong continuum. Acoustic results yield evidence that this voicing distinction is less robust than previously suggested and is redundant with a register contrast realized on following vowels through modulations of F1 at vowel onset (and more limited variations of F2 and voice quality). A perception experiment also shows that F1 weighs heavier than closure voicing in identification.

The Hallmarks of Predictive Oncology.

As the field of artificial intelligence evolves rapidly, these hallmarks are intended to capture fundamental, complementary concepts necessary for the progress and timely adoption of predictive modeling in precision oncology. Through these hallmarks, we hope to establish standards and guidelines that enable the symbiotic development of artificial intelligence and precision oncology.

The Basic Psychological Need Satisfaction and Frustration Scale: Some Satisfying and Frustrating Findings.

As a tool for operationalizing basic psychological needs theory (an aspect of self-determination theory), the Basic Psychological Needs Satisfaction and Frustration Scale (BPNSFS) has become the primary self-report measure. Here, with a sample of 807 Canadian military members, we confirm the BPNSFS six content factor structure and, in supporting that structure, demonstrate the differential association of satisfaction and frustration scales with psychological functioning variables that are external to the factor analysis. Although the specific content interpretation of the BPNSFS can be debated, we support the continued use of the BPNSFS as a psychometrically sound instrument.

Groundwater Ages in Intertill and Buried Valley Aquifers in Saskatchewan, Canada.

Continental glaciations during the Pleistocene Epoch created complex systems of aquifers and aquitards across many northern regions of the Earth. The low hydraulic conductivities of glacial till aquitards suggest that limited recharge will reach the underlying aquifers, potentially preserving old groundwaters. Here, we characterize the recharge history in intertill and buried valley aquifers in Saskatchewan, Canada using C, H, He δH, δO, and major ions.

Rapidly spreading with OXA-48-like carbapenemases.

(mostly , ) with OXA-48-like carbapenemases (e.g., OXA-48, -181, -232, -244) are undermining the global efficiency of carbapenem therapy.
