Nutrient Supplementation During The Prenatal Period In Substance-Using Mothers: A Narrative Review Of The Effects On Offspring Development., Catherine Serwatka, Adrianne K. Griebel-Thompson, Rina D. Eiden, Kai Ling Kong

Manuscripts, Articles, Book Chapters and Other Papers

Substance use during pregnancy increases the risk for poor developmental outcomes of the offspring, and for substance-dependent mothers, abstaining from substance use during pregnancy is often difficult. Given the addictive nature of many substances, strategies that may mitigate the harmful effects of prenatal substance exposure are important. Prenatal nutrient supplementation is an emerging intervention that may improve developmental outcomes among substance-exposed offspring. We provide a narrative review of the literature on micronutrient and fatty acid supplementation during pregnancies exposed to substance use in relation to offspring developmental outcomes. We first discuss animal models exposed to ethanol during pregnancy with supplementation …

In children with cardiomyopathy, the severity of heart failure (HF) varies. However, copeptin, which is a biomarker of neurohormonal adaptation in heart failure, has not been studied in these patients. In this study, we evaluated the correlation of copeptin level with functional HF grading, B-type natriuretic peptide (BNP), and echocardiography variables in children with cardiomyopathy. Furthermore, we determined if copeptin levels are associated with adverse outcomes, including cardiac arrest, mechanical circulatory support, heart transplant, or death. In forty-two children with cardiomyopathy with a median (IQR) age of 13.1 years (2.5–17.2) and a median follow-up of 2.5 years (2.2–2.7), seven (16.7%) …

Faculty, Staff and Students Publications

Pontine nuclei (PN) neurons mediate the communication between the cerebral cortex andthe cerebellum to refine skilled motor functions. Prior studies showed that PN neurons fall into two subtypes based on their anatomic location and region-specific connectivity, but the extent of their heterogeneity and its molecular drivers remain unknown. Atoh1 encodes a transcription factor that is expressed in the PN precursors. We previously showed that partial loss of Atoh1 function in mice results in delayed PN development and impaired motor learning. In this study, we performed single-cell RNA sequencing to elucidate the cell state–specific functions of Atoh1 during PN development and …

Sociology & Anthropology Department Faculty Publications

A large part of our material culture is made of organic materials, and this was likely the case also during prehistory. Amongst this prehistoric organic material culture are textiles and cordages, taking advantage of the flexibility and resistance of plant fibres. While in very exceptional cases and under very favourable circumstances, fragments of baskets and cords have survived and were discovered in late Pleistocene and Holocene archaeological sites, these objects are generally not preserved, especially in tropical regions. We report here indirect evidence of basket/tying material making found on stone tools dating to 39–33,000 BP from Tabon Cave, Palawan Philippines. …


Vascular And Auditory Changes After Repetitive Traumatic Brain Injury, Courtney Lynn Penn Jun 2023

Vascular And Auditory Changes After Repetitive Traumatic Brain Injury, Courtney Lynn Penn

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) affects over 2.87 million people in the US each year. The large majority of these injuries can be classified as mild. However, evidence suggests that even mild TBIs can lead to long-lasting symptoms that greatly impact quality of life. This is particularly true when an individual sustains multiple TBIs (repetitive TBI, rTBI). Much of the damage caused by rTBI is due to secondary injury mechanisms that cause the initial injury site to spread and worsen over time. No therapies currently exist which can mitigate secondary injury, and monitoring this phase of rTBI is difficult. Development of …

Tanzania Journal of Science

Leptospirosis is a neglected zoonotic disease, prominent in north-western Tanzania where interactions among humans, livestock and wildlife is high. This study therefore, assessed Leptospira seroprevalence and associated risk factors by screening Leptospira serovars from blood sera of cattle, goats and humans in Ngara and Kibondo Districts using Microscopic Agglutination Test (MAT). Blood sera were positive for seven Leptospira serovars in which Sokoine, Sejroe and Grippotyhposa had higher seropositivity of ≥ 20.9%, whereas Leptospira serovars Kenya, Pomona, Lora, and Bataviae had seropositivity of < 10%. Variation of seropositivity and seroprevalence between Ngara and Kibondo Districts was insignificant (p = 0.0718) but varied significantly between humans, goats and cattle (p = 0.0183). Leptospira serovars Sejroe and Grippotyphosa were present in humans, goats and cattle. Sokoine, Pomona and Bataviae were co-positive in humans and goats, while serovars Kenya and Lora were co-positive in humans and cattle, indicating the possibility of dualistic transmission of Leptospira serovars in the ecosystem. Suggested risk factors associated with acquiring Leptospira bacteria were drinking contaminated water, feeding contaminated food and farming in contaminated soils. Prevalence of Leptospira in the current study alerts for health and economic risks in north-western Tanzania, which requires intensive education programs on leptospirosis transmission and avoidance.
