Lead in Philadelphia’s Soils

Philadelphia has a long history of being a major player in the industrial revolution, particularly in the manufacturing of lead paint and varnishes. Philadelphia was home to manufacturers like ‘Philadelphia Lead Works,’ and the ‘National Lead Company.’ At one time, Philadelphia had 36 active lead smelters, almost twice more than any other industrial city, consequently causing higher lead concentrations than Flint, Michigan.

Mitochondrial targeting adaptation of the hominoid-specific glutamate dehydrogenase driven by positive Darwinian selection

Many new gene copies emerged by gene duplication in hominoids, but little is known with respect to their functional evolution. Glutamate dehydrogenase (GLUD) is an enzyme central to the glutamate and energy metabolism of the cell. In addition to the single, GLUD-encoding gene present in all mammals (GLUD1), humans and apes acquired a second GLUD gene (GLUD2) through retroduplication of GLUD1, which codes for an enzyme with unique, potentially brain-adapted properties. Here we show that whereas the GLUD1 parental protein localizes to mitochondria and the cytoplasm, GLUD2 is specifically targeted to mitochondria. Using evolutionary analysis and resurrected ancestral protein variants, we demonstrate that the enhanced mitochondrial targeting specificity of GLUD2 is due to a single positively selected glutamic acid-to-lysine substitution, which was fixed in the N-terminal mitochondrial targeting sequence (MTS) of GLUD2 soon after the duplication event in the hominoid ancestor ~18–25 million years ago. This MTS substitution arose in parallel with two crucial adaptive amino acid changes in the enzyme and likely contributed to the functional adaptation of GLUD2 to the glutamate metabolism of the hominoid brain and other tissues. We suggest that rapid, selectively driven subcellular adaptation, as exemplified by GLUD2, represents a common route underlying the emergence of new gene functions

Loss of Olfactory Receptor Genes Coincides with the Acquisition of Full Trichromatic Vision in Primates

Olfactory receptor (OR) genes constitute the molecular basis for the sense of smell and are encoded by the largest gene family in mammalian genomes. Previous studies suggested that the proportion of pseudogenes in the OR gene family is significantly larger in humans than in other apes and significantly larger in apes than in the mouse. To investigate the process of degeneration of the olfactory repertoire in primates, we estimated the proportion of OR pseudogenes in 19 primate species by surveying randomly chosen subsets of 100 OR genes from each species. We find that apes, Old World monkeys and one New World monkey, the howler monkey, have a significantly higher proportion of OR pseudogenes than do other New World monkeys or the lemur (a prosimian). Strikingly, the howler monkey is also the only New World monkey to possess full trichromatic vision, along with Old World monkeys and apes. Our findings suggest that the deterioration of the olfactory repertoire occurred concomitant with the acquisition of full trichromatic color vision in primates

The Pediatric Obsessive-Compulsive Disorder Treatment Study II: rationale, design and methods

This paper presents the rationale, design, and methods of the Pediatric Obsessive-Compulsive Disorder Treatment Study II (POTS II), which investigates two different cognitive-behavior therapy (CBT) augmentation approaches in children and adolescents who have experienced a partial response to pharmacotherapy with a serotonin reuptake inhibitor for OCD. The two CBT approaches test a "single doctor" versus "dual doctor" model of service delivery. A specific goal was to develop and test an easily disseminated protocol whereby child psychiatrists would provide instructions in core CBT procedures recommended for pediatric OCD (e.g., hierarchy development, in vivo exposure homework) during routine medical management of OCD (I-CBT). The conventional "dual doctor" CBT protocol consists of 14 visits over 12 weeks involving: (1) psychoeducation, (2), cognitive training, (3) mapping OCD, and (4) exposure with response prevention (EX/RP). I-CBT is a 7-session version of CBT that does not include imaginal exposure or therapist-assisted EX/RP. In this study, we compared 12 weeks of medication management (MM) provided by a study psychiatrist (MM only) with two types of CBT augmentation: (1) the dual doctor model (MM+CBT); and (2) the single doctor model (MM+I-CBT). The design balanced elements of an efficacy study (e.g., random assignment, independent ratings) with effectiveness research aims (e.g., differences in specific SRI medications, dosages, treatment providers). The study is wrapping up recruitment of 140 youth ages 7–17 with a primary diagnosis of OCD. Independent evaluators (IEs) rated participants at weeks 0,4,8, and 12 during acute treatment and at 3,6, and 12 month follow-up visits

Perception vs. Reality: Drinking on College Campuses

Many people believe that binge drinking is common among college students. However, existing research has conflicting data on the amount of alcohol that college students consume. The study implemented a survey of EKU students based on the Michigan State social norming campaign. This survey was used to gauge perceived drinking norms of students on campus and compare them to the actual drinking habits of those same students. One hundred and thirty-three students responded to the questionnaire. This research found that EKU college students perceived drinking norms to be much higher than they were. More than 42% of EKU students did not drink the last time they partied or socialized, yet 86% answered that they believed the average student consumed 3 drinks or more. The results indicate that drinking is not as common among college students as most people believe. A social marketing campaign was conducted during Homecoming week to demonstrate the differences in perceived norms and actual drinking habits and encourage safe behavior during the week\u27s festivities. Further training education concerning alcohol safety should continue to be a priority on college campuses. College students should not feel the need to drink to fit in.https://encompass.eku.edu/swps_graduategallery/1145/thumbnail.jp

Vasculitis Presenting as Autonomic Failure.

INTRODUCTION: Granulomatosis with polyangiitis (GPA) is a vasculitic process that can cause neurological dysfunction in addition to characteristic sinus and pulmonary manifestations. This case report highlights the spectrum of nervous system manifestations and includes rarely reported autonomic and pituitary involvement. CASE REPORT: A 62-year-old woman presented with orthostatic intolerance, tachycardia, dry mouth, and temperature sensitivity; subsequent autonomic reflex study demonstrated widespread postganglionic sympathetic sudomotor, cardiovagal, and cardiovascular adrenergic impairment reflective of autonomic neuropathy and overall autonomic failure. Additional progressive symptoms included dysarthria, dysphagia, bilateral hearing loss, voice hoarseness, and right-sided facial numbness with multiple cranial neuropathies identified on neurological examination. The diagnosis of central diabetes insipidus was also confirmed. Pachymeningitis was present on brain magnetic resonance imaging. Pathologic review of the dural biopsy specimen revealed necrotizing granulomatous vasculitis consistent with GPA. She was treated with intravenous methylprednisolone and rituximab. Over the next 2 months, she had near-complete resolution of her symptoms with normalization on repeat autonomic testing. CONCLUSIONS: This is a unique GPA case presenting with autonomic failure and pituitary dysfunction with conclusive objective findings of autonomic dysfunction. Autonomic dysfunction and other disease manifestations were responsive to immunosuppressive therapy

Elucidating mechanisms of quality‐of‐life disparities in Hispanic women with breast cancer: An examination of disease stage, coping, and affect

Objectives Compared to non‐Hispanic white (NHW) women, Hispanic women with breast cancer (BCa) are more likely to be diagnosed at later stages of disease and experience reduced quality of life (QOL) following diagnosis. We hypothesized that the demands of later‐stage disease results in a perceived inability to cope and greater distress for Hispanic women, resulting in decreased QOL. Methods Hispanic (51%) and NHW (49%) women (N = 198) with newly diagnosed stage 0–3 BCa in Miami were enrolled in two trials between 2006 and 2019. In this cross‐sectional analysis, a multiple‐group structural equation modeling approach was applied to baseline measures of coping confidence (Measure of Current Status Scale), negative and positive affect (Affect Balance Scale), QOL (Functional Assessment of Cancer Therapy – Breast), and disease stage. Results In our model, later‐stage disease was not associated with worse QOL for Hispanic or NHW women. However, there were differences between Hispanic and NHW women on the path from disease stage to (1) coping confidence, (2) positive affect, and (3) negative affect, such that later disease stage was associated with lower coping confidence (b[SE] = −1.75[0.59], p = 0.002), less positive affect (b[SE] = −0.21[0.10], p = 0.026), and greater negative affect (b[SE] = 0.15[0.08], p = 0.052) among Hispanic, but not NHW, women. In addition, an indirect effect was found from greater stage to poorer QOL via less positive affect among Hispanic women only (b[SE] = −0.49[0.24], p = 0.041). Conclusions This data supports our theory that Hispanic women experience worse emotional distress at later‐stage disease than do NHW women, in turn impacting QOL
