Mom Is Developing Too: Preliminary Evidence For The Reciprocal Effects Of Infant Sensory Reactivity And Maternal Behavior, Emily C. Sweiss, Vincent Berardi, Elysia Poggi Davis, Curt A. Sandman, Laura M. Glynn

Psychology Faculty Articles and Research

Caregiver sensitivity to infant cues is well-established as a predictor of child development. Infants also actively influence their social environment, especially their caregivers, even from their earliest days. Sensory reactivity, characterized as hypo- (under) and hyper- (over) responding to environmental stimuli, is one domain of development that is likely to influence caregiver-infant interaction, due to its role in regulating emotions and responses to both physical and social stimuli. Although sensory reactivity could be an important target for improving caregiver-child interaction, the longitudinal, reciprocal relations between infant sensory reactivity and caregiver behaviors are currently unknown. In the present proof-of-concept study, we …

Oral Health

Abstract

In the absence of formal training, licensure, and professionalism, this scientific literature review will seek to include denturists in the American maxillofacial prosthetics industry. Denturists are oral health professionals who perform oral examination, design, manufacture, and place removable oral prostheses. In other regions of the world, they are also known as clinical dental technologists and dental prosthetists. This practice is not widespread in the US. The review can also be assessed on the model mediated by PRISMA, which is concentrated on the experiences of international education in the United Kingdom, Canada, and Australia, where the concentration further revolves around …

Partial Versus Full Revision In Cementless Single-Stage Exchange For Hip Periprosthetic Joint Infection: A Multicenter Comparative Study With 10-Year Survivorship Analysis, Wenbo Mu, Atthakorn Jarusriwanna, Boyong Xu, Scot A. Brown, Xiaogang Zhang, Alexander Dawes, Javad Parvizi Md, Li Cao

Rothman Institute Papers

BACKGROUND: Periprosthetic joint infection (PJI) is one of the most challenging complications following total hip arthroplasty (THA). Traditional management typically involves full revision to ensure comprehensive infection eradication. However, for patients with well-fixed implants, partial revision in a single-stage cementless approach may provide a viable alternative, potentially preserving bone stock and reducing operative time. The relative efficacy of this approach compared with full revision remains to be fully explored. This multicenter study aims to determine whether partial revision in cementless single-stage exchange surgery offers comparable infection control outcomes to full revision for select patients with well-fixed implants.

METHODS: We conducted …

Race And Patient-Physician Communication On Blood Pressure Management: Helping Improve Care, Samar A. Nasser, Ashley Pender, Ayan Ali, Kardie Tobb, Keith C. Ferdinand

Division of Cardiology Faculty Papers

PURPOSE OF REVIEW: To provide an overview of the relationship of race and ethnicity and patient-physician/clinician communication on blood pressure management.

RECENT FINDINGS: The suboptimal interactions experienced by patients from underrepresented racial and ethnic populations may be improved by enriching relationships among clinicians, population health scientists, policymakers, and community members/leaders. Current care communication and policies for managing hypertension appear to be insufficient. Implementing and disseminating effective strategies to efficiently improve the quality of hypertension care and recognize social determinants of health among minoritized populations is intertwined with enhanced communication.

Faculty, Staff and Student Publications

Background: Abnormal levels of VWF (von Willebrand Factor) are a risk factor for venous thromboembolism (VTE) and bleeding. Genome-wide association studies for VWF have identified novel candidate genes that may regulate VWF levels in humans, including RAB5C (RAS-associated protein RAB5C). We hypothesized that RAB5C regulates VWF release from endothelial cells.

Methods: We studied the effect of RAB5C on vesicle trafficking in human endothelial cells. We performed CRISPR (clustered regularly interspaced short palindromic repeats) interference targeting 2 genetic variants linked to altered VWF levels and evaluated RAB5C expression by reverse transcription-quantitative polymerase chain reaction. We silenced RAB5C or overexpressed RAB5C wild-type, …

Introduction: Hepatocellular carcinoma (HCC) can develop in individuals with metabolic dysfunction-associated steatotic liver disease (MASLD) without cirrhosis, especially in those with elevated liver enzymes. However, there is currently no low-cost, scalable screening tool for this population. To address this need, we investigated the association between serial changes in FIB-4 (fibrosis-4) scores over a 3-year period and the risk of developing HCC in a large, diverse cohort of patients with MASLD without cirrhosis.

Methods: This study utilized a nationwide cohort from the National Health Insurance Research Database (NHIRD), including 810,698 patients with MASLD who had demographic and laboratory data at baseline …

Policy, Misinformation, And Mortality: The Effects Of Abortion Restrictions On Maternal Outcomes, Gabrielle Samiratedu Dmsc, Mcms, Pa-C

Lynchburg Journal of Medical Science

The objective of this review is to evaluate the effects of restrictive abortion laws on maternal mortality and morbidity in the United States. Even before the landmark reversal of Roe v. Wade, the US had one of the highest maternal mortality rates among other high-income countries, and rates are expected to continue to rise in states with restrictive abortion policies. Electronic databases and public health data were analyzed to assess clinical outcomes, access to care, and disparities associated with abortion restrictions nationally and internationally. The findings suggest that states with highly restrictive abortion policies experience higher rates of maternal morbidity …

Faculty, Staff and Students Publications

Women diagnosed with metastatic triple negative breast cancer (mTNBC) have limited treatment options, are more prone to develop resistance and are associated with high mortality. A cold tumor immune microenvironment (TIME) characterized by low T cells and high tumor associated macrophages (TAMs) in mTNBC is associated with the failure of standard-of-care chemotherapy and immune checkpoint blockade (ICB) treatment. We demonstrate that the combination of immunomodulatory low-dose Cyclophosphamide (CTX) coupled with anti-CSF-1R antibody targeted therapy (SNDX-ms6352) and anti-PD-1 (ICB), was highly effective against aggressive metastatic Trp53 null TNBC transplantable syngeneic models that present with high macrophage infiltration. Mechanistically, CSF-1R inhibition along …

Reverse Koebner Phenomenon In Linear Scalp Morphea Following Punch Biopsy: A Rare Therapeutic Response, Suhas C. Gowda, Akshay Samagani, Shreyas C. Gowda

Digital Journal of Clinical Medicine

Morphea is a chronic immune-mediated fibrosing disorder characterized by excessive collagen deposition in the skin. Linear morphea of the scalp (en coup de sabre) commonly demonstrates the Koebner phenomenon, wherein lesions develop at sites of trauma; however, the reverse Koebner phenomenon—trauma-induced regression—is exceptionally rare. We report an unusual case of linear scalp morphea showing early regression following a diagnostic punch biopsy. A 71-year-old male presented with an asymptomatic, indurated linear plaque on the scalp of two months’ duration. Histopathology from a 3.5-mm punch biopsy confirmed morphea, demonstrating dense collagen bundles with lymphoplasmacytic infiltrate. At follow-up eight days after …
