Acculturation And Immigrant Parental Perceptions Concerning Sexual Communication, Kwame Owura Frimpong

Journal of Human Services Scholarship and Interprofessional Collaboration

Abstract:

Acculturation presents challenges to many immigrant parents that are adjusting to new lives in the United States. The rationale for conducting this study stemmed from the effects that acculturation can have on the wellbeing of immigrants, adversely affecting their health outcomes. The purpose of this study was to explore the perceptions of Sub-Saharan African immigrant parents concerning having a conversation with their pre-adolescent children about sexuality and sexual practices. Findings revealed communication barriers due to cultural beliefs, cultural taboos, and shame. The findings from this study are beneficial to behavioral healthcare providers that work with immigrant families, parents, and …

Effects Of Thoracic Spine Mobilization On The Lumbar Spine Rotation Angle During Trunk Rotation, Toru Yasuda, Ryota Yoshida, Hironobu Kuruma

Asian Journal of Physical Therapy

Objectives: Limitations in the thoracic spine movement can cause excessive lumbar rotation and back pain; however, it is unclear whether increasing thoracic rotation reduces excessive lumbar rotation. This study aimed to examine the effect of thoracic spine mobilization on the rotation angle of the lumbar spine during trunk rotation. Methods: Twenty healthy volunteers participated in this study. We identified and then mobilized three restricted vertebrae in the thoracic spine through a physical examination using a facet joint traction mobilization technique. Rotational movements of both the thoracic and lumbar spine were assessed pre- and post-intervention. Measurement items included: (1) lumbar rotational …

An Exploratory Metabolomic Comparison Of Participants With Fast Or Absent Functional Progression From 2care, A Randomized, Double-Blind Clinical Trial In Huntington's Disease., Andrew Mcgarry, Krystal Hunter, John Gaughan, Peggy Auinger, Thomas N Ferraro, Basant Pradhan, Luigi Ferrucci, Josephine M Egan, Ruin Moaddel Jan 2024

An Exploratory Metabolomic Comparison Of Participants With Fast Or Absent Functional Progression From 2care, A Randomized, Double-Blind Clinical Trial In Huntington's Disease., Andrew Mcgarry, Krystal Hunter, John Gaughan, Peggy Auinger, Thomas N Ferraro, Basant Pradhan, Luigi Ferrucci, Josephine M Egan, Ruin Moaddel

Cooper Medical School of Rowan University Departmental Research

Huntington's disease (HD) is increasingly recognized for diverse pathology outside of the nervous system. To describe the biology of HD in relation to functional progression, we previously analyzed the plasma and CSF metabolome in a cross-sectional study of participants who had various degrees of functional impairment. Here, we carried out an exploratory study in plasma from HD individuals over a 3-year time frame to assess whether differences exist between those with fast or absent clinical progression. There were more differences in circulating metabolite levels for fast progressors compared to absent progressors (111 vs 20, nominal p < 0.05). All metabolite changes in faster progressors were decreases, whereas some metabolite concentrations increased in absent progressors. Many of the metabolite levels that decreased in the fast progressors were higher at Screening compared to absent progressors but ended up lower by Year 3. Changes in faster progression suggest greater oxidative stress and inflammation (kynurenine, diacylglycerides, cysteine), disturbances in nitric oxide and urea metabolism (arginine, citrulline, ornithine, GABR), lower polyamines (putrescine and spermine), elevated glucose, and deficient AMPK signaling. Metabolomic differences between fast and absent progressors suggest the possibility of predicting functional decline in HD, and possibly delaying it with interventions to augment arginine, polyamines, and glucose regulation.

School of Medicine Faculty Publications

We present a patient with an intraventricular hemorrhage. Imaging identified a left atrial intraventricular mass and a vague adjacent second periventricular cystic lesion. A guided trans-sulcal approach via a left parietal craniotomy resulted in a gross total resection of both lesions. These represented two distinct lesions, the periventricular cystic lesion was an extraventricular neurocytoma (EVN) and a World Health Organization grade 1 choroid plexus papilloma (CPP). The neurocytoma required methylation studies for confirmatory diagnosis. The patient had an uneventful recovery with a normal neurological exam at 12-weeks. This documents the occurrence of two distinct central nervous system tumors, a CPP …

BACKGROUND: Specific peripheral proteins have been implicated to play an important role in the development of Alzheimer's disease (AD). However, the roles of additional novel protein biomarkers in AD etiology remains elusive. The availability of large-scale AD GWAS and plasma proteomic data provide the resources needed for the identification of causally relevant circulating proteins that may serve as risk factors for AD and potential therapeutic targets.

METHODS: We established and validated genetic prediction models for protein levels in plasma as instruments to investigate the associations between genetically predicted protein levels and AD risk. We studied 71,880 (proxy) cases and 383,378 …

School of Medicine Faculty Publications

Third-degree burn injuries pose a significant health threat. Safer, easier-to-use, and more effective techniques are urgently needed for their treatment. We hypothesized that covalently bonded conjugates of fatty acids and tripeptides can form wound-compatible hydrogels that can accelerate healing. We first designed conjugated structures as fatty acid–aminoacid1–amonoacid2–aspartate amphiphiles (Cn acid–AA1–AA2–D), which were potentially capable of self-assembling into hydrogels according to the structure and properties of each moiety. We then generated 14 novel conjugates based on this design by using two Fmoc/tBu solid-phase peptide synthesis techniques; we verified their structures and purities through liquid chromatography with tandem mass spectrometry and nuclear …

Chlormethine Gel In Combination With Other Therapies For Treatment Of Mycosis Fungoides: A Review With Patient Cases, Marco Ardigò, Neda Nikbakht, Miriam Teoli, Laura Gleason, Liliana Crisan, Christiane Querfeld

Department of Dermatology and Cutaneous Biology Faculty Papers

Topical chlormethine gel has been approved as monotherapy for treatment of adult patients with mycosis fungoides (MF), the most common form of cutaneous T-cell lymphoma. In clinical practice, chlormethine gel is often combined with other skin-directed or systemic therapies to optimize response and target recalcitrant lesions. Positive outcomes with combination regimens using chlormethine gel and topical corticosteroids, phototherapy, retinoids, methotrexate, or interferon-α have been reported in literature. However, there are no treatment guidelines on the use of combination regimens with chlormethine gel. To provide real-world evidence and guidance on the use of chlormethine gel combination regimens, several cases of patients …

Mendelian randomization has been widely used to assess the causal effect of a heritable exposure variable on an outcome of interest, using genetic variants as instrumental variables. In practice, data on the exposure variable can be incomplete due to high cost of measurement and technical limits of detection. In this paper, we propose a valid and efficient method to handle both unmeasured and undetectable values of the exposure variable in one-sample Mendelian randomization analysis with individual-level data. We estimate the causal effect of the exposure variable on the outcome using maximum likelihood estimation and develop an expectation maximization algorithm for …

Biallelic pathogenic variants in neuroblastoma-amplified sequence (NBAS) cause a pleiotropic multisystem disorder. Three clinical subgroups have been defined correlating with the localisation of pathogenic variants in the NBAS gene; variants affecting the C-terminal region of NBAS result in SOPH syndrome (short stature, optic atrophy, Pelger-Huët anomaly), variants affecting the Sec 39 domain are associated with infantile liver failure syndrome type 2 (ILFS2) and variants affecting the ß-propeller domain give rise to a combined phenotype. However, there is still unexplained phenotypic diversity across the three subgroups, challenging the current concept of genotype-phenotype correlations in NBAS-associated disease. Therefore, besides examining the genetic …

Machine learning (ML) techniques have gained popularity in the neuroimaging field due to their potential for classifying neuropsychiatric disorders. However, the diagnostic predictive power of the existing algorithms has been limited by small sample sizes, lack of representativeness, data leakage, and/or overfitting. Here, we overcome these limitations with the largest multi-site sample size to date (N = 5365) to provide a generalizable ML classification benchmark of major depressive disorder (MDD) using shallow linear and non-linear models. Leveraging brain measures from standardized ENIGMA analysis pipelines in FreeSurfer, we were able to classify MDD versus healthy controls (HC) with a balanced accuracy …

Penile squamous cell carcinoma (PSCC) is a rare and deadly malignancy. Therapeutic advances have been stifled by a poor understanding of disease biology. Specifically, the immune microenvironment is an underexplored component in PSCC and the activity of immune checkpoint inhibitors observed in a subset of patients suggests immune escape may play an important role in tumorigenesis. Herein, we explored for the first time the immune microenvironment of 57 men with PSCC and how it varies with the presence of human papillomavirus (HPV) infection and across tumor stages using multiplex immunofluorescence of key immune cell markers. We observed an increase in …

Section of Neurology

This review focuses on emerging risk factors for stroke, including air pollution and climate change, gut microbiota, high altitude, and systemic infection. Up to 14% of all stroke-associated mortality is attributed to air pollution and is more pronounced in developing countries. Fine particulate matter and other air pollutants contribute to an increased stroke risk, and this risk appears to increase with higher levels and duration of exposure. Short term air pollution exposure has also been reported to increase the stroke risk. The gut microbiota is a complex ecosystem of bacteria and other microorganisms that reside in the digestive system and …

In this article, we share insights regarding an arts-based research project where carers of people with dementia conveyed their experiences in cloth. Carers face high rates of mental ill health and burnout, while forming a largely undervalued and unrecognised workforce. Through this project, carers’ knowledge was valued and amplified using an innovative methodology – craftivism. During a series of five workshops in 2021, a small group of carers, researchers and artists gathered online to develop an exhibition of craftivist textile works. They evoked the complexity of their makers’ journeys supporting loved ones at the end of life, finding joy and …

Dietary restriction (DR) delays aging, but the mechanism remains unclear. We identified polymorphisms in mtd, the fly homolog of OXR1, which influenced lifespan and mtd expression in response to DR. Knockdown in adulthood inhibited DR-mediated lifespan extension in female flies. We found that mtd/OXR1 expression declines with age and it interacts with the retromer, which regulates trafficking of proteins and lipids. Loss of mtd/OXR1 destabilized the retromer, causing improper protein trafficking and endolysosomal defects. Overexpression of retromer genes or pharmacological restabilization with R55 rescued lifespan and neurodegeneration in mtd-deficient flies and endolysosomal defects in fibroblasts from patients with lethal loss-of-function …

β-Lactamase enzymes hydrolyze and thereby provide bacterial resistance to the important β-lactam class of antibiotics. The OXA-48 and NDM-1 β-lactamases cause resistance to the last-resort β-lactams, carbapenems, leading to a serious public health threat. Here, we utilized DNA-encoded chemical library (DECL) technology to discover novel β-lactamase inhibitors. We exploited the β-lactamase enzyme-substrate binding interactions and created a DECL targeting the carboxylate-binding pocket present in all β-lactamases. A library of 10

Several cancer core regulatory circuitries (CRCs) depend on the sustained generation of DNA accessibility by SWI/SNF chromatin remodelers. However, the window when SWI/SNF is acutely essential in these settings has not been identified. Here we used neuroblastoma (NB) cells to model and dissect the relationship between cell-cycle progression and SWI/SNF ATPase activity. We find that SWI/SNF inactivation impairs coordinated occupancy of non-pioneer CRC members at enhancers within 1 hour, rapidly breaking their autoregulation. By precisely timing inhibitor treatment following synchronization, we show that SWI/SNF is dispensable for survival in S and G2/M, but becomes acutely essential only during G1 phase. …

Mitosis is a critical criterion for meningioma grading. However, pathologists' assessment of mitoses is subject to significant inter-observer variation due to challenges in locating mitosis hotspots and accurately detecting mitotic figures. To address this issue, we leverage digital pathology and propose a computational strategy to enhance pathologists' mitosis assessment. The strategy has two components: (1) A depth-first search algorithm that quantifies the mathematically maximum mitotic count in 10 consecutive high-power fields, which can enhance the preciseness, especially in cases with borderline mitotic count. (2) Implementing a collaborative sphere to group a set of pathologists to detect mitoses under each high-power …

This study examined the role that cytokines may have played in the beneficial outcomes found when outpatient individuals infected with SARS-CoV-2 were transfused with COVID-19 convalescent plasma (CCP) early in their infection. We found that the pro-inflammatory cytokine IL-6 decreased significantly faster in patients treated early with CCP. Participants with COVID-19 treated with CCP later in the infection did not have the same effect. This decrease in IL-6 levels after early CCP treatment suggests a possible role of inflammation in COVID-19 progression. The evidence of IL-6 involvement brings insight into the possible mechanisms involved in CCP treatment mitigating SARS-CoV-2 severity.

The bromodomain inhibitor (+)-JQ1 is a highly validated chemical probe; however, it exhibits poor in vivo pharmacokinetics. To guide efforts toward improving its pharmacological properties, we identified the (+)-JQ1 primary metabolite using chemical catalysis methods. Treatment of (+)-JQ1 with tetrabutylammonium decatungstate under photochemical conditions resulted in selective formation of an aldehyde at the 2-position of the thiophene ring [(+)-JQ1-CHO], which was further reduced to the 2-hydroxymethyl analog [(+)-JQ1-OH]. Comparative LC/MS analysis of (+)-JQ1-OH to the product obtained from liver microsomes suggested (+)-JQ1-OH as the major metabolite of (+)-JQ1. The 2-thienyl position was then substituted to generate a trideuterated (−CD3, (+)-JQ1-D) …

Introduction:

Diets low in vegetables are a main contributor to the health burden experienced by young adults in rural communities. Digital health interventions provide an accessible delivery model that can be personalised to meet the diverse preferences of young adults. A personalisable digital vegetable intake intervention (Veg4Me) was codesigned to meet the needs of young adults living in rural communities. This study will determine the feasibility of delivering a personalised Veg4Me programme and compare preliminary effects with a non-personalised Veg4Me (control).

Methods and Analysis:

A 12-week assessor-blinded, two-arm, parallel randomised controlled trial will be undertaken from August 2023 until April …

Lung Cancer Masquerading As Thoracolumbar Pain Detected In An Outpatient Physical Therapy Setting, Jeremiah Blankenship

Asian Journal of Physical Therapy

Study Design: Case Study. Background: This case report describes the clinical course of a patient with right low back pain (LBP) and the use of clinical evaluation findings to initiate medical referral resulting in a diagnosis of cancer presenting as mechanical low back pain. Diagnosis: A 59-year-old male with primary complaints of progressive right-sided LBP affecting his job, sleep, and daily activities was seen by a physical therapist in an outpatient setting. The components of the patient’s history and physical examination were consistent with mechanical thoracolumbar dysfunction. However, clustered examination findings suggested the possibility of a more serious underlying disease. …

Use Of Syringe Service Programs In Rural Vs Urban Maine: A Harm-Reduction Study, Lisa W. Miller, Kim Murray, Emma Daybranch, Kinna Thakarar

Journal of Maine Medical Center

Introduction: Syringe service programs (SSPs) reduce HIV and viral hepatitis transmission, as well as the prevalence of improperly disposed needles and needle stick injuries among first responders. Infections associated with injection drug use are rising in rural areas, including Maine, leading to concerns that SSP services are difficult to access for rural residents.

Methods: A cross-sectional survey of 101 participants hospitalized with infections associated with injection drug use at 4 hospitals in Maine was collected over a 15-month period. Descriptive analyses were performed. Statistical analyses were completed using Fisher’s exact tests, Pearson’s chi-squared tests, and Student’s t tests.

Results: Of …
