We conducted a cross-sectional study among HIV-positive adults age ≥ 50 in San Francisco to evaluate the frequency of loneliness, characteristics of those who reported loneliness, and the association of loneliness with functional impairment and health-related quality of life (HRQoL). Participants (N = 356) were predominately male (85%); 57% were white; median age was 56. 58% reported any loneliness symptoms with 24% reporting mild, 22% moderate and 12% severe loneliness. Lonely participants were more likely to report depression, alcohol and tobacco use, and have fewer relationships...

PURPOSE: To assess whether the higher prevalence of childhood trauma exposure but lower prevalence of alcohol use in Black vs. White adolescent girls reflects a lower magnitude of association between trauma and alcohol use initiation in Black girls; and additionally, whether low socioeconomic status (SES) and neighborhood factors account in part for the link between trauma and early alcohol use. METHODS: Data were drawn from annual interviews conducted with an urban sample of girls and their primary caregivers from ages 5-8 (baseline) through age 17 (n = 2068, 57...

BACKGROUND The optic radiation (OR) is a white-matter bundle connecting the lateral geniculate body and the visual cortex. Phase difference-enhanced imaging (PADRE) is a new MRI technique that is able to achieve precise delineation of the OR. The aim of this study was to investigate the effect of age on the volume and signal intensity of the OR using PADRE, and to establish a volumetric reference of the OR from a healthy population, compared with diffusion tensor imaging (DTI). MATERIAL AND METHODS Thirty-nine healthy volunteers underwent MR imaging with PADRE and DTI sequences on a 3...

BACKGROUND: Black women have one of the highest prevalence rates of hypertension and obesity in the United States. We previously reported that sympathetic activation induced by obesity is a significant contributor to hypertension in white patients. It is unknown whether sympathetic activity similarly contributes to hypertension in obese black women. METHODS AND RESULTS: We studied 42 obese women (16 white, body mass index 36±4 kg/m(2), 44% with hypertension; 26 black, body mass index 35±4 kg/m(2), 46% with hypertension)...

Aicardi-Goutières syndrome is an early-onset severe neurological disorder characterized by intracranial calcification, white matter abnormalities, hepatosplenomegaly, cerebrospinal fluid lymphocytosis, and elevated interferon-α levels, thus mimicking congenital viral infections. It is a genetically heterogeneous condition and autosomal recessive and autosomal dominant forms with variations in seven genes known till date. Variations in RNASEH2C cause an autosomal recessive form of AGS. Here we report three Indian families with variant, c...

PURA syndrome is a recently described developmental encephalopathy presenting with neonatal hypotonia, feeding difficulties, global developmental delay, severe intellectual disability, and frequent apnea and epilepsy. We describe 18 new individuals with heterozygous sequence variations in PURA. A neuromotor disorder starting with neonatal hyptonia, but ultimately allowing delayed progression to walking, was present in nearly all individuals. Congenital apnea was present in 56% during infancy, but all cases in this cohort resolved during the first year of life...

PURPOSE: Racial disparities in cancer treatment-related symptom burden are well documented and linked to worse treatment outcomes. Yet, little is known about racial differences in patients' treatment-related symptom management experiences. Such understanding can help identify modifiable drivers of symptom burden inequities. As part of the Cancer Health Accountability for Managing Pain and Symptoms (CHAMPS) study, we examined racial differences in symptom management experiences among Black and White breast cancer survivors (BCS)...

BACKGROUND: PET ligands targeting the translocator protein (TSPO) represent promising tools to visualise neuroinflammation. Here, we analysed parameters obtained in dynamic and static PET images using the novel TSPO ligand [(18)F]GE-180 in patients with relapsing remitting multiple sclerosis (RRMS) and an approach for semi-quantitative assessment of this disease in clinical routine. Seventeen dynamic [(18)F]GE-180 PET scans of RRMS patients were evaluated (90 min). A pseudo-reference region (PRR) was defined after identification of the least disease-affected brain area by voxel-based comparison with six healthy controls (HC) and upon exclusion of voxels suspected of being affected in static 60-90 min p...

Vibrio parahaemolyticus (Vp) and Vibrio vulnificus (Vv) are naturally occurring estuarine bacteria and are the leading causes of seafood-associated infections and mortality in the USA. Though multiple-antibiotic resistant Vp and Vv have been reported resistance patterns in vibrios are not as well documented as other food-borne bacterial pathogens. Salinity relaying (SR) is a Post-Harvest Processing (PHP) treatment to reduce the abundance of these pathogens in shellfish harvested during the warmer months. The purpose of this study was to evaluate the antimicrobial susceptibility (AMS), pathogenicity and genetic profiles of Vp and Vv recovered from oysters during an oyster relay study...

Genetically modified crops that express insecticidal Bacillus thuringiensis (Bt) proteins have become a primary approach for control of lepidopteran (moth) and coleopteran (beetle) pests that feed by chewing the plants. However, the sap-sucking insects (Hemiptera) are not particularly susceptible to Bt toxins. In this study, we describe two Cry toxins (Cry64Ba and Cry64Ca) from a Bt 1012 strain showed toxicity against two important rice hemipteran pests, Laodelphax striatellus and Sogatella furcifera Both of these two proteins contain an ETX/MTX2 domain, and share common sequence features with the β-pore forming toxins...

Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss and blindness in developed nations. AMD is anticipated to affect 196 million people worldwide, by 2020. However, the etiology of this disease remains unknown. Aging, genetic, and environmental influences have generally been implicated as major etiologic factors. We sought to examine the hypothesis that consumption of the 'displacing foods of modern commerce,' which equate to processed, nutrient-deficient and potentially toxic foods, may be the primary and proximate cause of AMD...

Black walnut (Juglans nigra), slippery elm (Ulmus rubra), and white ash (Fraxinus americana) trees were evaluated as potential archives of past uranium (U) contamination. Like other metals, U mobility in annual growth rings of trees is dependent on the tree species. Uranium concentrations and isotopic compositions (masses 234, 235, 236, and 238) were analyzed by thermal ionization mass spectrometry to test the efficacy of using tree rings to retroactively monitor U pollution from the FFMPC, a U purification facility operating from 1951 to 1989...

REVIEW
Madelyn H Labella
The current paper systematically reviews empirical research on parental emotion socialization in African American families, addressing gaps in a literature that has historically focused on White middle class samples. Of the 1210 studies screened, 329 were inspected, 280 were excluded, and 49 were included. Studies addressed emotion-related beliefs and attitudes, emotion expressiveness, discussion of emotion, and responses to children's emotion. Mixed findings are interpreted in light of sociocultural factors...
