Vaccine Uptake and Intentions: Insights from a Texas Survey on Factors Influencing COVID-19 Vaccination Decisions.

The effectiveness of COVID-19 vaccines depends on widespread vaccine uptake. Employing a telephone-administered weighted survey with 19,502 participants, we examined the determinants of COVID-19 vaccine acceptance among adults in Texas. We used multiple regression analysis with LASSO-selected variables to identify factors associated with COVID-19 vaccine uptake and intentions to receive the vaccine among the unvaccinated. The prevalence of unvaccinated individuals (22%) was higher among those aged 18-39, males, White respondents, English speakers, uninsured individuals, those facing financial challenges, and individuals expressing no concern about contracting the illness. In a fully adjusted regression model, higher odds of being unvaccinated were observed among males (aOR 1.11), the uninsured (aOR 1.38), smokers (aOR 1.56), and those facing financial struggles (aOR 1.62). Conversely, Asians, Blacks, and Hispanics were less likely to be unvaccinated compared to Whites. Among the unvaccinated, factors associated with stronger intent to receive the vaccine included age (over 65 years), Black and Hispanic ethnicity, and perceived risk of infection. Hispanic individuals, the uninsured, those covered by public insurance, and those facing financial challenges were more likely to encounter barriers to vaccine receipt. These findings underscore the importance of devising tailored strategies, emphasizing nuanced approaches that account for demographic, socioeconomic, and attitudinal factors in vaccine distribution and public health interventions.

Parental Factors Associated with COVID-19 Vaccine Uptake for Children over 5 Years of Age in Texas.

The COVID-19 vaccine is safe and effective for children, yet parental hesitancy towards vaccinating children against the virus persists. We conducted a telephone-administered weighted survey in Texas to examine parents' sociodemographic factors and medical conditions associated with COVID-19 vaccination intention for parents with unvaccinated children ages 5-17 years. We collected responses from 19,502 participants, of which 4879 were parents of children ages 5-17 years. We conducted multiple logistic regression with Lasso-selected variables to identify factors associated with children's vaccination status and parents' intention to vaccinate their children. From the unweighted sample, less than half of the parents (46.8%) had at least one unvaccinated child. These parents were more likely to be White, English-speaking, not concerned about illness, privately insured, and unvaccinated for COVID-19 themselves (p < 0.001). In the adjusted regression model, parents who were unvaccinated (vs. having COVID-19 booster, aOR = 28.6) and financially insecure (aOR = 1.46) had higher odds of having unvaccinated children. Parents who were Asian (aOR = 0.50), Black (aOR = 0.69), Spanish-speaking (aOR = 0.57), concerned about illness (aOR = 0.63), had heart disease (aOR = 0.41), and diabetes (aOR = 0.61) had lower odds of having unvaccinated children. Parents who were Asian, Black, Hispanic, Spanish-speaking, concerned about illness for others, and vaccine-boosted were more likely to have vaccination intention for their children (p < 0.001). Children's vaccination is essential to reduce COVID-19 transmission. It is important to raise awareness about the value of pediatric COVID-19 vaccination while considering parents' sociodemographic and medical circumstances.

Differences in beliefs about COVID-19 by gun ownership: a cross-sectional survey of Texas adults.

OBJECTIVES: We investigated the association between gun ownership and perceptions about COVID-19 among Texas adults as the pandemic emerged. We considered perceived likelihood that the pandemic would lead to civil unrest, perceived importance of taking precautions to prevent transmission and perceptions that the threat of COVID-19 has been exaggerated. METHODS: Data were collected from 5 to 12 April 2020, shortly after Texas' stay-at-home declaration. We generated a sample using random digit dial methods for a telephone survey (n=77, response rate=8%) and by randomly selecting adults from an ongoing panel to complete the survey online (n=1120, non-probability sample). We conducted a logistic regression to estimate differences in perceptions by gun ownership. To account for bias associated with use of a non-probability sample, we used Bayesian data integration and ran linear regression models to produce more accurate measures of association. RESULTS: Among the 60% of Texas adults who reported gun ownership, estimates of past 7-day gun purchases, ammunition purchases and gun carrying were 15% (n=78), 20% (n=100) and 24% (n=130), respectively. We found no evidence of an association between gun ownership with perceived importance of taking precautions to prevent transmission or with perceived likelihood of civil unrest. Results from the logistic regression (OR 1.27, 95% CI 0.99 to 1.63) and the linear regression (ß=0.18, 95% CI 0.07 to 0.29) suggest that gun owners may be more likely to believe the threat of COVID-19 was exaggerated. CONCLUSIONS: Compared with those without guns, gun owners may have been inclined to downplay the threat of COVID-19 early in the pandemic.

An examination of racial and ethnic disparities in mental health during the Covid-19 pandemic in the U.S. South.

BACKGROUND: The mental health of racial/ethnic minority groups in the United States may be disproportionately impacted by the COVID-19 pandemic due to greater experience of peri-pandemic stressors. Yet, few studies have systematically examined racial/ethnic differences in mental health outcomes in this context. METHODS: Data came from the COVID-19 Southern Cities Study, a probability-based, cross-sectional study conducted in May/June 2020 among adults living in the metropolitan statistical areas of Atlanta, Austin, Dallas, Houston, and New Orleans. Unadjusted and adjusted associations between racial/ethnic identity and past-week depression and/or anxiety symptoms (Patient Health Questionnaire-2 score ≥ 3 or Generalized Anxiety Disorder-2 score ≥ 3), trouble sleeping, physical reactions when thinking about COVID-19, and self-rated worsened mental health due to the pandemic were estimated in separate logistic regression models. RESULTS: Over 30% of respondents reported depression and/or anxiety symptoms, 21% reported physical reactions, 25% had trouble sleeping, and 33% worsened mental health since the pandemic began. Adjusting for sociodemographic and health-related characteristics and pandemic-related stressors, odds of anxiety symptoms (odds ratio (OR) 0.53, 95% confidence interval (CI) 0.30-0.95) and worsened mental health (OR 0.58, 95% CI 0.36-0.94) were lower among non-Hispanic Black vs. non-Hispanic white respondents. LIMITATIONS: No diagnostic assessments were used, and results may not be generalizable to later phases of the pandemic and the entire U.S. South. CONCLUSIONS: Despite greater pandemic-related stressor experience, poor mental health outcomes were not more common among racial/ethnic minority individuals. However, interventions to reduce disparities in stressor experience and promote mental health are needed.

QuilliChew extended-release chewable tablets for the treatment of ADHD in patients ages 6 years old and above.

INTRODUCTION: Attention-deficit/hyperactivity disorder (ADHD) is a common neurobehavioral disorder affecting as many as 6.4 million children and adolescents in the United States. Since amphetamine (AMPH) and methylphenidate (MPH) were found to be effective more than 60 years ago, numerous formulations of these compounds have been developed. New preparations have focused on convenience, with extended-release (ER) drugs allowing once-daily dosing. Multiple ER formulations do not require patients to swallow a tablet or capsule. Recent ER preparations include liquids, oral disintegrating tablets, and chewable tablets. Several new formulations use ion exchange technology containing both immediate-release and ER components. Areas covered: Quillichew ERTM (MPH-ERCT) is an ER methylphenidate designed to be chewed before swallowing. The technology and pharmacokinetics, along with efficacy and safety data, are presented. Expert opinion: Extensive safety and efficacy data exist for MPH. ER formulations can be distinguished by preparation (tablet, capsule, liquid) and onset and duration of effect, but efficacy is similar for all ER MPH products. Each formulation has attributes, such as ease of titration, portability, and taste, that make it more acceptable for certain patients. Because AMPH and MPH are so effective, current technology research is focused on improving safety, convenience, and onset and duration of effect.

Tools for outcome prediction in patients with community acquired pneumonia.

INTRODUCTION: Community-acquired pneumonia (CAP) is one of the most common causes of mortality world-wide. The mortality rate of patients with CAP is influenced by the severity of the disease, treatment failure and the requirement for hospitalization and/or intensive care unit (ICU) management, all of which may be predicted by biomarkers and clinical scoring systems. Areas covered: We review the recent literature examining the efficacy of established and newly-developed clinical scores, biological and inflammatory markers such as C-Reactive protein (CRP), procalcitonin (PCT) and Interleukin-6 (IL-6), whether used alone or in conjunction with clinical severity scores to assess the severity of CAP, predict treatment failure, guide acute in-hospital or ICU admission and predict mortality. Expert commentary: The early prediction of treatment failure using clinical scores and biomarkers plays a developing role in improving survival of patients with CAP by identifying high-risk patients requiring hospitalization or ICU admission; and may enable more efficient allocation of resources. However, it is likely that combinations of scoring systems and biomarkers will be of greater use than individual markers. Further larger studies are needed to corroborate the additive value of these markers to clinical prediction scores to provide a safer and more effective assessment tool for clinicians.

Ductal barriers in mammary epithelium.

Tissue barriers play an integral role in the biology and pathobiology of mammary ductal epithelium. In normal breast physiology, tight and adherens junctions undergo dynamic changes in permeability in response to hormonal and other stimuli, while several of their proteins are directly involved in mammary tumorigenesis. This review describes first the structure of mammary ductal epithelial barriers and their role in normal mammary development, examining the cyclical changes in response to puberty, pregnancy, lactation and involution. It then examines the role of adherens and tight junctions and the participation of their constituent proteins in mammary tumorigenic functions such as migration, invasion and metastasis. Finally, it discusses the potential of these adhesion proteins as both prognostic biomarkers and potential therapeutic targets in breast cancer.

Lipid rafts are disrupted in mildly inflamed intestinal microenvironments without overt disruption of the epithelial barrier.

Intestinal epithelial barrier disruption is a feature of inflammatory bowel disease (IBD), but whether barrier disruption precedes or merely accompanies inflammation remains controversial. Tight junction (TJ) adhesion complexes control epithelial barrier integrity. Since some TJ proteins reside in cholesterol-enriched regions of the cell membrane termed lipid rafts, we sought to elucidate the relationship between rafts and intestinal epithelial barrier function. Lipid rafts were isolated from Caco-2 intestinal epithelial cells primed with the proinflammatory cytokine interferon-γ (IFN-γ) or treated with methyl-ß-cyclodextrin as a positive control for raft disruption. Rafts were also isolated from the ilea of mice in which colitis had been induced in conjunction with in vivo intestinal permeability measurements, and lastly from intestinal biopsies of ulcerative colitis (UC) patients with predominantly mild or quiescent disease. Raft distribution was analyzed by measuring activity of the raft-associated enzyme alkaline phosphatase and by performing Western blot analysis for flotillin-1. Epithelial barrier integrity was estimated by measuring transepithelial resistance in cytokine-treated cells or in vivo permeability to fluorescent dextran in colitic mice. Raft and nonraft fractions were analyzed by Western blotting for the TJ proteins occludin and zonula occludens-1 (ZO-1). Our results revealed that lipid rafts were disrupted in IFN-γ-treated cells, in the ilea of mice with subclinical colitis, and in UC patients with quiescent inflammation. This was not associated with a clear pattern of occludin or ZO-1 relocalization from raft to nonraft fractions. Significantly, a time-course study in colitic mice revealed that disruption of lipid rafts preceded the onset of increased intestinal permeability. Our data suggest for the first time that lipid raft disruption occurs early in the inflammatory cascade in murine and human colitis and, we speculate, may contribute to subsequent disruption of epithelial barrier function.

Military issues.

This article reviews of some of the lessons in trauma psychiatry learned by the US military through wartime and other trauma experiences during the past century. Current practice in the military's employment of stress control teams is reviewed. The military's efforts to prevent and limit psychological casualties, to include the care of battle casualties and prisoners of war (POWs), are addressed. Recent experiences that have informed further, and are shaping the military's approach to managing the psychological aftermath of trauma (such as the Sept. 11, 2001, attack on the Pentagon and the current war with Iraq) are included. Guidelines developed after 9/11, and articulated in the "Mass Violence and Early Intervention" conference are presented. Finally, current ideas on preparation for and intervention after weapons of mass destruction will be outlined.

Allergic rhinitis in children with attention-deficit/hyperactivity disorder.

BACKGROUND: Both allergic rhinitis and attention-deficit/hyperactivity disorder (ADHD) are common pediatric conditions associated with learning difficulties and sleep disturbances. There are conflicting research data regarding the association between ADHD and atopic disorders. OBJECTIVE: To determine the prevalence of allergic rhinitis in patients with physician-diagnosed ADHD. METHODS: Patients 5 to 18 years of age who presented with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of ADHD to an outpatient pediatric psychiatry clinic were screened for allergic rhinitis with focused history, physical examination, and skin prick testing to common aeroallergens. RESULTS: Thirty patients were interviewed, with 23 of these undergoing physical examination and skin prick testing. Eighty percent reported allergic rhinitis symptoms, whereas 61% had at least 1 positive prick skin test result. Forty-three percent showed typical physical signs of allergic rhinitis, 100% had a positive atopic family history, and 53% had other associated atopic disorders. CONCLUSIONS: Most children with ADHD displayed symptoms and skin prick test results consistent with allergic rhinitis. Nasal obstruction and other symptoms of allergic rhinitis could explain some of the cognitive patterns observed in ADHD, which might result from sleep disturbance known to occur with allergic rhinitis. Therefore, evaluation and treatment of allergic rhinitis could benefit patients with ADHD.

Pain in infancy: conceptual and methodological issues.

The concept of pain in infancy was explored. It was suggested that our every day usage of the term pain be applied to infants. Essentially this suggestion is that we infer that an infant has a subjective experience that is unpleasant when there is evidence of tissue damage and the infant responds with signs of distress, such as crying, increased heart rate, facial expression consistent with distress or other signs. Conceptualizations of adult clinical pain and infant emotions were compared. It was proposed that our concept of infant pain should be multivariate and should include the ecological context in which pain occurs. In section 2 methodological issues were discussed. Ethical concerns for the protection of infant rights were voiced. Numerous opportunities for studying infant pain produced by necessary medical procedures were pointed out. A number of response systems which offer promise in understanding infant pain were reviewed with respect to their proven applicability to infant emotional and cognitive processes or to adult pain processes. This paper attempted to organize information which will be helpful to the researcher interested in infant pain or developmental processes in pain. From the preceding it should be obvious how remarkably little data we have which bears directly on the issue. The close association between the study of pain and the study of emotion has been shown. The study of emotional development, while ahead of the study of developmental aspects of pain, still lags far behind the study of cognitive development. Recently there has been a call for increased study of the development of emotion. The study of the development of pain might well proceed hand in hand. The present state of the field of infant pain is such that almost any data will add to our knowledge base. The complexity of the concept and the wide range of response systems would suggest that multidisciplinary research teams may develop some of the best research efforts. A multidisciplinary approach has been found to be essential in the treatment of chronic pain, for example. A listing of some of the types of professionals who would contribute would include: physicians, nurses, psychologists, biologists (including those trained in neurophysiology, ethology and endocrinology), sociologists and anthropologists. University medical centers seem an ideal environment for conducting such research, given the close proximity of various specialists and an available subject population.

Pain in infancy: neonatal reaction to a heel lance.

A combined single subject and group design was used to investigate changes in heart rate and crying in response to a heel lance, non-invasive tactile stimulation and baseline periods in 10 male and 10 female infants, each in their second full day of life. Heart rate was measured with an electrocardiogram. Percentage of time crying was computed from observations of audiotapes. Results for individual subjects indicated that heart rate and percentage of crying were consistently increased by the heel lance but that there was often wide baseline variability in the two measures. Analysis of variance indicated that responses to heel lance were higher than responses to tactile stimulation which were in turn higher than responses to baseline for both heart rate and percentage of crying (P less than 0.01). No significant sex differences were found. It was suggested that the increases in heart rate and crying in the context of a tissue damaging stimulus indicated that the infants experienced pain and that pain in infants can be reliably measured in clinical settings.
