Objectives: Achieving widespread vaccine acceptance across various employment sectors is key to a successful public health response to COVID-19, but little is known about factors influencing vaccine acceptance among essential non-health care workers. We examined factors influencing vaccine acceptance among a sample of essential non-health care workers in California.

Methods: We conducted a survey in early spring 2021 at 2 corporations in Los Angeles County, California, to identify and describe factors influencing vaccine acceptance and the ability of incentives to increase this acceptance.

Safe Robot Trajectory Control Using Probabilistic Movement Primitives and Control Barrier Functions.

In this paper, we present a novel means of control design for probabilistic movement primitives (ProMPs). Our proposed approach makes use of control barrier functions and control Lyapunov functions defined by a ProMP distribution. Thus, a robot may move along a trajectory within the distribution while guaranteeing that the system state never leaves more than a desired distance from the distribution mean.

Can an amino acid mixture alleviate gastrointestinal symptoms in neuroendocrine tumor patients?

Background: Neuroendocrine tumors, although relatively rare in incidence, are now the second most prevalent gastrointestinal neoplasm owing to indolent disease biology. A small but significant sub-group of neuroendocrine tumor patients suffer from diarrhea. This is usually secondary to carcinoid syndrome but can also be a result of short gut syndrome, bile acid excess or iatrogenic etiologies.

Augmented resting beat-to-beat blood pressure variability in young, healthy, non-Hispanic black men.

New Findings: What is the central question of this study? The prevalence of hypertension in black individuals exceeds that in other racial groups. Despite this well-known heightened risk, the underlying contributory factors remain incompletely understood. We hypothesized that young black men would exhibit augmented beat-to-beat blood pressure variability compared with white men and that black men would exhibit augmented total peripheral resistance variability.

To provide a baseline of various driving behaviors and to identify opportunities for prevention of distracted driving during the infancy of state laws that prohibited cellphone use while operating a motor vehicle, the 2010-2011 Distracted Driving Survey collected information on multiple distracted driving behaviors from lower-income clients of three designated, multi-purpose public health centers in Los Angeles County. Descriptive and multivariable negative binomial regression analyses were performed to examine patterns of driving distractions using the Distracted Driving Survey dataset ( = 1,051). The most common distractions included talking to other passengers ( = 912, 86.

Prediabetes, diabetes, and other CVD-related conditions among Asian populations in Los Angeles County, 2014.

To assess the prevalence of four common health conditions related to cardiovascular disease risk among Asians in Los Angeles County. A survey of Asians in Los Angeles County was conducted utilizing purposive sampling to recruit from the region's Service Planning Areas 3 and 4; these underserved areas contain high density of Asian populations. Descriptive and multivariable regression analyses were performed to explore and describe potential associations between self-reported diagnoses of prediabetes, diabetes, hypertension, and high cholesterol and body mass index (measured with non-Asian versus Asian cut points) by race/ethnicity (Chinese/Filipino/Korean/Taiwanese/Thai/Vietnamese).

Reasons why low-income people in urban areas do not drink tap water.

Background: Despite its higher cost and potential environmental effect compared with those of tap water, bottled water consumption has been increasing over the past decade, especially in low-income communities in which children are at a higher risk of developing caries.

Methods: The authors used a systematic sequential sampling design for the Water Consumption Survey to collect information about water consumption beliefs and practices from clients attending 4 public health centers in Los Angeles County (LAC). The authors used health belief model constructs to examine why some low-income residents in LAC do not drink tap water.

Perfectionistic cognitions and eating disturbance: distinct mediational models for males and females.

Objective: Perfectionism has long been known to correlate with eating disturbance (ED). One mechanism through which this personality tendency may lead to ED is through increasing one's daily perfectionistic thoughts. This study examined the mediating role of perfectionistic thinking in the personality perfectionism-ED relationship among both male and female college students, and included measures assessing both typically-male and typically-female ED symptoms.

A Pseudomonas aeruginosa EF-hand protein, EfhP (PA4107), modulates stress responses and virulence at high calcium concentration.

Pseudomonas aeruginosa is a facultative human pathogen, and a major cause of nosocomial infections and severe chronic infections in endocarditis and in cystic fibrosis (CF) patients. Calcium (Ca2+) accumulates in pulmonary fluids of CF patients, and plays a role in the hyperinflammatory response to bacterial infection. Earlier we showed that P.

A simple and generic approach for synthesizing colloidal metal and metal oxide nanocrystals.

A simple and generic approach--alternating voltage induced electrochemical synthesis (AVIES)--has been reported for synthesizing highly dispersed colloidal metal (Au, Pt, Sn, and Pt-Pd) and metal oxide (ZnO and TiO2) nanocrystals. The respective nanocrystals are produced when a zero-offset alternating voltage at 60 Hz is applied to a pair of identical metal wires, which are inserted in an electrolyte solution containing capping ligands. In the case of Au, the obtained nanocrystals are highly crystalline nano-icosahedra of 14 ± 2 nm in diameter, the smallest Au icosahedra synthesized in aqueous solutions via green chemistry.
