The consumption of micronutrients in relation to calorie intake and risk of insulin resistance.

Background And Aims: Adequate dietary intakes of essential micronutrients are critical to prevent insulin resistance (IR)-related diseases. Even though the excess calorie intake linked with obesity is also associated with such diseases, no previous studies evaluated the importance of meeting the Dietary Reference Intake (DRI) of micronutrients in relation to calorie intake in those at risk for developing IR.

Methods And Results: We evaluated the relationship between the ability or failure to meet the DRI of micronutrients in relation to daily calorie intake in 463 childbearing-age women with a higher prevalence of IR.

Isoform-Specific Role of GSK-3 in High Fat Diet Induced Obesity and Glucose Intolerance.

Obesity-associated metabolic disorders are rising to pandemic proportions; hence, there is an urgent need to identify underlying molecular mechanisms. Glycogen synthase kinase-3 (GSK-3) signaling is highly implicated in metabolic diseases. Furthermore, GSK-3 expression and activity are increased in Type 2 diabetes patients.

Depressive Symptoms and Risk of Stroke in a National Cohort of Black and White Participants From REGARDS.

Objective: The purpose of this study was to examine depressive symptoms as a risk factor for incident stroke and determine whether depressive symptomatology was differentially predictive of stroke among Black and White participants.

Methods: The study comprised 9,529 Black and 14,516 White stroke-free participants, aged 45 and older, enrolled in the REasons for Geographic and Racial Differences in Stroke (2003-2007). Incident stroke was the first occurrence of stroke.

Ornithine decarboxylase (ODC1) gene variant (rs2302615) is associated with gastric cancer independently of Helicobacter pylori CagA serostatus.

The primary cause of gastric cancer is chronic infection with Helicobacter pylori (H. pylori), particularly the high-risk genotype cagA, and risk modification by human genetic variants. We studied 94 variants in 54 genes for association with gastric cancer, including rs2302615 in ornithine decarboxylase (ODC1), which may affect response to chemoprevention with the ODC inhibitor, eflornithine (difluoromethylornithine; DFMO).

In this narrative, we explore our own perspectives as faculty who guide students through a simulated poverty experience.

DACH1 as a multifaceted and potentially druggable susceptibility factor for kidney disease.

Kidney diseases affect more than 15% of adults in the US, yet drug development in the kidney field, when compared with that for other common diseases, has been lagging behind. Modifiers that increase the susceptibility to injury and contribute to the pathogenesis and progression of kidney disease include genetic and environmental factors and epigenetic mechanisms. In this issue of the JCI, Cao et al.

Intracranial EEG evidence of functional specialization for taxonomic and thematic relations.

The dual-hub account posits that the neural organization of semantic knowledge is segregated by the type of semantic relation with anterior temporal lobe (ATL) specializing for taxonomic relations and inferior parietal lobule (IPL) for thematic relations. This study critically examined this account by recording intracranial EEG from an array of depth electrodes within ATL, IPL, and two regions within the semantic control network, inferior frontal gyrus (IFG) and posterior middle temporal gyrus (pMTG), while 17 participants with refractory epilepsy completed a semantic relatedness judgment task. We observed a significant difference between relation types in ATL and IPL approximately 600-800 ms after trial presentation, and no significant differences in IFG or pMTG.

The accuracy of HPV genotyping in isolation and in combination with CD4 and HIV viral load for the identification of HIV-infected women at risk for developing cervical cancer.

Background: Human papillomavirus (HPV) genotype testing has limited utility to identify human immunodeficiency virus-infected (HIV+) women's risk for developing cervical cancer (CC) due to high positivity rate of high-risk (HR) HPVs. We investigated the accuracy of HPV testing in isolation/in combination with CD4 and HIV viral load (VL) to identify HIV+ women at risk for developing CC.

Methods: Study consisted of 344 HIV+ women on combination antiretroviral therapy (cART), tested for cervical cytology/HPV using the Cobas test and had data on absolute CD4 count and VL measurements.

Carotid Stump Syndrome: An Uncommon Cause of Recurrent Ipsilateral Strokes.

Carotid stump syndrome is a rare cause of recurrent cerebrovascular accidents. Carotid stump is the patent proximal remnant below the completely occluded internal carotid artery (ICA). Cerebral and retinal ischemic symptoms seen after complete occlusion of ipsilateral ICA is known as carotid stump syndrome.

Cancer-related Beliefs and Preventive Health Practices among Residents of Rural versus Urban Counties in Alabama.

Higher prevalence of cancer-related risk factors, for example, tobacco use, obesity, poor diet, and physical inactivity, is observed in the U.S. Deep South and likely contributes to its increased cancer burden.

Proteotoxicity: A Fatal Consequence of Environmental Pollutants-Induced Impairments in Protein Clearance Machinery.

A tightly regulated protein quality control (PQC) system maintains a healthy balance between correctly folded and misfolded protein species. This PQC system work with the help of a complex network comprised of molecular chaperones and proteostasis. Any intruder, especially environmental pollutants, disrupt the PQC network and lead to PQCs disruption, thus generating damaged and infectious protein.

Differences Related to Cancer Screening by Minority and Rural/Urban Status in the Deep South: Population-based Survey Results.

Cancer mortality in the U.S. Deep South exceeds national levels.

Secondary analysis of gut hormone data from children with and without in utero exposure to gestational diabetes: Differences in the associations among ghrelin, GLP-1, and insulin secretion.

Background: Intrauterine exposure to gestational diabetes mellitus (GDM) increases risk for type 2 diabetes (T2D). Ghrelin and GLP-1 have opposite functions in nutritional homeostasis and are associated with insulin secretion, but it is not known if individuals exposed to GDM exhibit dysregulation in these associations.

Objective: Test the hypothesis that children exposed to GDM in utero will exhibit dysregulation among ghrelin, GLP-1, and C-peptide (reflecting insulin secretion).

Prevalence and Associated Dietary Factors of Rome IV Functional Gastrointestinal Disorders in Rural Western Honduras.

Background: The literature is limited regarding the prevalence of functional gastrointestinal disorders (FGIDs) in Central America, and the role of dietary factors.

Methods: The Rome IV diagnostic questionnaire and National Cancer Institute Diet History questionnaire were administered in one-on-one interviews to a distributed cross section of the general adult population of Western Honduras. Our aim was to estimate prevalence of common FGIDs and symptoms and their relationships to dietary habits.

Forskolin rapidly enhances neuron-like morphological change of directly induced-neuronal cells from neurofibromatosis type 1 patients.

Aim: Neurofibromatosis type 1 (NF1) is a multifaceted disease, and frequently comorbid with neurodevelopmental disorders such as autism spectrum disorder (ASD) and learning disorder. Dysfunction of adenylyl cyclase (AC) is one of the candidate pathways in abnormal development of neuronal cells in the brain of NF1 patients, while its dynamic abnormalities have not been observed. Direct conversion technology can generate induced-neuronal (iN) cells directly from human fibroblasts within 2 weeks.

To assess subjective sleep quality and sleep patterns among adults, the Pittsburgh Sleep Quality Index (PSQI) is a well and internationally established tool. Here, we established the psychometric properties of the Persian version of the PSQI for adolescents.

The Story of the Silent Killer : A History of Hypertension: Its Discovery, Diagnosis, Treatment, and Debates.

Hypertension is the leading risk factor for death and disability-adjusted life-years lost globally. Despite this tremendous impact on health, blood pressure measurement and treatment are relatively new to medical practice, with widespread measurement beginning just over 100 years ago. How, in such a short time, did blood pressure become such an integral measurement in medical practice that it is now considered one of the vital signs? Key revelations through Stephen Hales and his horse experiment, Riva-Rocci's modern blood pressure cuff, Korotkoff sounds, and President Roosevelt's death set the stage for discovery.

Neuraxial anaesthesia and peripheral nerve blocks during the COVID-19 pandemic: a literature review and practice recommendations.

Coronavirus disease 2019 (COVID-19) has had a significant impact on global healthcare services. In an attempt to limit the spread of infection and to preserve healthcare resources, one commonly used strategy has been to postpone elective surgery, whilst maintaining the provision of anaesthetic care for urgent and emergency surgery. General anaesthesia with airway intervention leads to aerosol generation, which increases the risk of COVID-19 contamination in operating rooms and significantly exposes the healthcare teams to COVID-19 infection during both tracheal intubation and extubation.

Psychometric Properties of Clinical Tests of Balance and Vestibular-Related Function in Children With Cerebral Palsy.

Purpose: The purpose of this study was to establish the psychometric properties of clinical tests of balance and vestibular-related function in children with cerebral palsy (CP), aged 7 to 12 years, Gross Motor Function Classification System levels I to III.

Methods: Forty-two children with CP and 33 children with typical development were examined using Clinical Dynamic Visual Acuity Test, Modified Clinical Test of Sensory Interaction on Balance, Head Impulse Test, Bucket Test, and Northeastern State University College of Optometry oculomotor test. A subgroup was tested twice for reliability.

Impact of ketosis on appetite regulation-a review.

To reduce the health burden of obesity, it is important to identify safe and practical treatments that are effective for weight loss while concurrently preventing weight regain. Diet-induced weight loss is usually followed by a concomitant increase in ghrelin secretion and feelings of hunger, which may compromise weight loss goals and increase the risk of weight regain. The aim of this review is to describe the status of knowledge regarding the impact of ketosis, induced by diet or exogenous ketones (ketone esters), on appetite and the potential mechanisms involved.

T cell infiltration in both human multiple system atrophy and a novel mouse model of the disease.

Multiple system atrophy (MSA) is a progressive neurodegenerative disorder characterized by abnormal accumulation of alpha-synuclein (α-syn) in oligodendrocytes accompanied by inflammation, demyelination, and subsequent synapse and neuronal loss. Little is known about the mechanisms of neurodegeneration in MSA. However, recent work has highlighted the important role of the immune system to the pathophysiology of other synuclein-related diseases such as Parkinson's disease.

A rigorous exploration of anal HPV genotypes using a next-generation sequencing (NGS) approach in HIV-infected men who have sex with men at risk for developing anal cancer.

Background: There are no HPV-based measures for managing anal cancer (AC) in HIV-infected (HIV+) men who have sex with men (MSM) because of the high positivity of high-risk (HR)-HPVs. As next-generation sequencing (NGS) is able to describe the composition of HPVs as percent (%) reads rather than positive vs negative results, we used NGS approach to detect HPVs in anal samples of HIV+ MSM to test its ability to differentiate those who are diagnosed with atypical squamous cells of unknown significance or greater (ASCUS+) from those who are free of such lesions and to understand the burden of HPV infections in relation to HPV vaccines.

Methods: Study included 81 HIV+ MSM characterized for demographics, patient-reported outcome measures, HIV related laboratory measures and anal cytology.
