Travel history among persons infected with SARS-CoV-2 variants of concern in the United States, December 2020-February 2021.

The first three SARS-CoV-2 phylogenetic lineages classified as variants of concern (VOCs) in the United States (U.S.) from December 15, 2020 to February 28, 2021, Alpha (B.

Development of a Data Visualization Tool for Occupational Exposure to Chemicals of Concern for Breast Cancer Among California Working Women, 2010-2014.

We identified the occupations that employ California women and a list of chemicals of concern for breast cancer. We evaluated the likelihood of on-the-job exposure to the categories of chemicals by occupation among formally and informally employed women. We selected 145 occupations representing more than 6.

Monoamine oxidase inhibitory activity of flavoured e-cigarette liquids.

Background And Aims: Monoamine oxidase inhibitors have been hypothesised to be important in tobacco dependence, reinforcing the brain's response to nicotine by delaying the degradation of neurotransmitters by monoamine oxidases. The development of electronic cigarettes has provided an alternative nicotine delivery system, which is widely viewed as less toxic than tobacco smoke. However, significant data gaps remain.

Blood basophil activation is a reliable biomarker of allergic bronchopulmonary aspergillosis in cystic fibrosis.

The diagnosis of cystic fibrosis (CF) patients with allergic bronchopulmonary aspergillosis (ABPA) is clinically challenging, due to the absence of an objective biological test. Since blood basophils play a major role in allergic responses, we hypothesised that changes in their surface activation pattern discriminate between CF patients with and without ABPA.We conducted a prospective longitudinal study (Stanford cohort) comparing basophil activation test CD203c levels by flow cytometry before and after activation with Aspergillus fumigatus allergen extract or recombinant Asp f1 in 20 CF patients with ABPA (CF-ABPA) and in two comparison groups: CF patients with A.

Utilization of psychiatric services by postpartum women in a predominantly minority, low-socioeconomic-status, urban population.

This study describes the utilization of health care services related to psychiatric diagnoses in an inner city community health organization with a largely Hispanic population of low socioeconomic status. We reviewed the frequency and timing of postpartum mental health diagnoses among 5,731 patients who delivered babies and were followed-up for postpartum care. 286 women (5 %) had at least one mental health diagnosis.

Presymptomatic risk assessment for chronic non-communicable diseases.

The prevalence of common chronic non-communicable diseases (CNCDs) far overshadows the prevalence of both monogenic and infectious diseases combined. All CNCDs, also called complex genetic diseases, have a heritable genetic component that can be used for pre-symptomatic risk assessment. Common single nucleotide polymorphisms (SNPs) that tag risk haplotypes across the genome currently account for a non-trivial portion of the germ-line genetic risk and we will likely continue to identify the remaining missing heritability in the form of rare variants, copy number variants and epigenetic modifications.

Consumer perceptions of direct-to-consumer personalized genomic risk assessments.

Purpose: To evaluate consumer perceptions of direct-to-consumer personalized genomic risk assessments and assess the extent to which consumer characteristics may be associated with attitudes toward testing.

Methods: Adult participants aged 18-85 years of age purchased a personalized genomic risk test at a subsidized rate and were administered a web-based health assessment that included questions regarding perceptions and attitudes toward undergoing testing.

Results: Assessments were obtained for 3640 individual study participants, and 49.

Fish consumption and advisory awareness among low-income women in California's Sacramento-San Joaquin Delta.

Fishing is a culturally important activity to the ethnically diverse population living in California's Sacramento-San Joaquin Delta. Due to runoff from abandoned gold mines, certain Delta fish are contaminated with methylmercury, a neurodevelopmental toxin. A state health advisory recommends limited consumption of certain Delta fish, to be followed in conjunction with a federal advisory for commercial and sport fish.

Effect of antioxidant intake on sperm chromatin stability in healthy nonsmoking men.

Oxidative stress is detrimental to sperm function and a significant factor in the etiology of male infertility. This report examines the association between dietary and supplementary intake of the antioxidants vitamin C, vitamin E, and beta-carotene and sperm chromatin integrity. Eighty-seven healthy male volunteers donated semen samples, completed food-frequency questionnaires, and provided information about their sociodemographic characteristics, medical and reproductive histories, and lifestyle habits.
