g. symptoms, risks) at a medium effect size, but not to information-seeking skills, prevention intentions, or prevention behaviors. Health literacy was independently related to all measured aspects of COVID-19 health information and did not interact with neurocognition in any COVID-19 health domain.Conclusions Individual differences in neurocognition and health literacy played independent and meaningful roles in the initial acquisition of knowledge related to COVID-19, which is a novel human health condition. Future studies might examine whether neurocognitive supports (e.g. spaced retrieval practice, elaboration) can improve COVID-19-related knowledge and health behaviors in vulnerable populations.

High-mobility group box 1 (HMGB1) protein has been noticed particularly for its pivotal role in several pathologies. However, the relevance between HMGB1 and pathological progress in lung toxicity still remains unclear. In the study, we evaluated the effect of glycyrrhizic acid as an HMGB1 inhibitor on the early inflammation and late fibrosis in bleomycin-induced pulmonary toxicity in mice.

We established a bleomycin-induced pulmonary toxicity model to detect the relevance between HMGB1 and pathological changes in the early inflammatory and late fibrotic stages.

We found that bleomycin-induced increase in inflammatory cytokines interleukin (IL)-β1, tumor necrosis factor (TNF)-α, monocyte chemotactic protein (MCP)-1, and inflammatory lesions in lung tissue in the early stage of the model. However, markers of fibrosis such as transforming growth factor (TGF)-β1 and α-smooth muscle actin (α-SMA) were significantly elevated on day 7 after bleomycin instillation. Interestingly, HMGB1 also began to rise on day 7, rather than in the early inflammatory phase. However, early (from day 0 to 14 after bleomycin instillation) or late (from day 14 to 28) intervention with HMGB1 neutralizing antibody or glycyrrhizic acid alleviated inflammation and fibrosis through down-regulating the inflammatory signaling mitogen-activated protein kinase (MAPK) and fibrotic signaling Smad3 pathway.

Our results suggested that HMGB1 mediates both inflammation and fibrosis in this model. The development of high-potency and low-toxicity HMGB1 inhibitors may be a class of potential drugs for the treatment of pulmonary fibrosis.

One medical college and one nonmedical college were selected using convenience sampling, and the respondents were identified using stratified cluster sampling. A DCE focused on vaccine-related and service-related attributes was conducted in 2019. Latent class analysis was used to estimate the vaccine-related attributes, and conditional logistic regression was used to construct the choice model for the service-related attributes. In total, 850 female college students finished the study. Two latent classes were identified. Those who had more knowledge of HPV and felt more pressure about the related infection and diseases had a significantly higher chance of belonging to class 1 and were more likely to choose vaccination (percentages of respondents choosing no vaccination was 1.1% in class 1 versus 84.7% in class 2, χ2 = 641.1, P less then .01). There were 742 respondents who chose vaccination in vaccine-related scenes, and 98.8% of them still chose to receive the vaccine in service-related scenes. Ways of making an appointment, number of weeks waiting for vaccination, service time for vaccination, time to the nearest vaccination site, and added cost all impacted the probability of choosing HPV vaccination services. It is concluded that higher levels of HPV knowledge and sociopsychological pressure led to a higher probability of HPV vaccination uptake in China. It is necessary to disseminate proper knowledge of HPV to improve the coverage and equality of HPV vaccination.The purpose of this study is to evaluate the attitudes of healthcare professionals toward the COVID -19 vaccine, which has been introduced to healthcare professionals at the beginning of 2021 and give information to them on the disease and vaccine. This cross-sectional analytical study has been performed by conducting an online survey to the healthcare professionals who work at the healthcare institutions in the province of Samsun in Turkey between December 2020 and January 2021. In addition to sixteen questions about the demographic characteristics, the "Attitudes towards the COVID -19 vaccine" scale has been used. MANOVA test and Spearman rho correlation coefficient were used in analytical examinations. A total of 1426 healthcare professional have been reached. 64.3% of participants were female, 44.1% were nurse/midwife and 66.6% were public employees. Regarding the questions in the sub-dimension of positive attitude, the rate of response of "I agree/I strongly agree" was between 40.6% and 54.6%. Positive attitude mean values differ according to gender, age, institution, presence of children, smoking status, being a relative who died due to COVID -19, and profession (respectively p less then .001, p less then .001, p less then .001, p less then .001, p = .002, p = .019, p less then .001). It has been observed that positive and negative attitudes toward COVID -19 vaccination are almost equally distributed and some demographic factors affect the attitude. The opinions of healthcare professionals on the safety and effectiveness of the vaccine, which are the main elements of the vaccination effort, may affect the public perception of vaccination.The aim of this study was to determine concentrations of metals in peel, pulp, and seeds of grapes obtained from family farms in Brazil, compare them to the maximum threshold levels and to evaluate the risk by estimating the daily intake (EDI). Grape samples were collected from farms and levels of Cd, Cr, Cu, Mn, Ni, Pb and Zn were assessed via ICP-MS. The highest metal levels were found in grape peels, Cu at the highest concentration (107.6 mg kg-1). Cr, Cu, and Pb were found at concentrations which exceeded maximum threshold levels. The EDI of Cd, Cu and Pb through consumption of grapes for the assessed Brazilian population was 0.29, 1822 and 3.02 µg/kg bw/day, respectively. The EDI of Cu was above the Provisionary Tolerable Daily Intake (PTDI). Thus, there are possible health risks due to the occurrence of Cu in Brazilian grapes.ABSTRACTSOur previous study first investigated feasibility of applying ultrasound (US) and microbubbles (MBs) via external auditory canal to facilitate drug delivery into inner ear. However, most drugs are in aqueous formulae and eliminated via Eustachian tubes after drug application. In this study, feasibility of sustained release of thermosensitive poloxamer 407 (P407)-based MB gel for US mediation-enhanced inner ear drug (dexamethasone, DEX) delivery was investigated. Subasumstat The sol-to-gel transition temperature showed that mixture of DEX and only 10% and 12.5% P407 in MBs can be used for in vitro and in vivo drug delivery experiments. In in vitro Franz diffusion experiments, the release rates of 12.5% P407-MBs + US groups in the model using DEX as the delivered reagent at 3 h resulted in values 1.52 times greater than those of 12.5% P407-MBs groups. In guinea pigs, by filling tympanic bulla with DEX in 12.5% P407-MBs (DEX-P407-MBs), USMB applied at post-treatment days 1 and 7 induced 109.13% and 66.67% increases in DEX delivery efficiencies, respectively, compared to the group without US. On the 28th day after US-mediated P407-MB treatment, the safety assessment showed no significant changes in the hearing thresholds and no damage to the integrity of cochlea or middle ear. These are the first results to demonstrate feasibility of US-modified liquid form DEX-P407-MB cavitation for enhancing permeability of round window membrane. Then, a gel form of DEX-P407-MBs was generated and thus prolonged the release of DEX in middle ear to maintain the therapeutic DEX level in inner ear for at least 7 days.A patient is in close proximity to different types of textiles in hospital environment, which contribute to the transfer of drug-resistant bacteria in healthcare settings. This study was undertaken to estimate the temporal variations in bacterial load on bedsheets in a primary healthcare unit in Delhi. Data were collected for a period of 7 months. Antibiotic susceptibility testing of isolates was performed. The mean count of Acinetobacter spp. was highest (2.10 × 102 CFU/cm2), and Klebsiella spp. showed the least mean count (7.5 × 101 CFU/cm2). The mean bacterial count over the period showed maximum bacterial load for most microbial groups in June, and minimum in November. Enterococcus faecalis and Streptococcus spp. were highly resistant to different antibiotics, while Acinetobacter spp. and Group A Streptococcus showed the least resistance toward the antibiotics tested. Bacterial counts on bedsheets were found to vary with the time of the year, indicating that environmental factors affect bacterial load.Patients with life-threatening illnesses in intensive care receive management that improves their chances for survival. The physical outcomes of individuals infected with HIV who survive an intensive care unit (ICU) stay are not well known. The purpose was to describe the physical outcomes of ICU survivors in a high HIV prevalent area and highlight challenges as it relates to study feasibility. A pilot study at a tertiary-care university-affiliated hospital was done. Participants were assessed at ICU and ward admission, hospital discharge, three and six months following discharge. The profile and physical function, assessed with the ICU Mobility Scale, Karnofsky Performance Status Scale and six-minute walk test, of participants was determined. The EQ-5D-3 L provides information on participants' health-related quality of life (HRQOL). The pilot study consists of five patients (n = 173 screened). All were independently mobile and on antiretroviral therapy prior to hospital admission. Respiratory and peripheral muscle weakness were present with variable performance in physical function across participants. Improvement in function occurred over time but participants still had physical dysfunction at six months. Pain/physical discomfort and anxiety/depression were common complaints influencing HRQOL. ICU survivors, who are HIV-positive, present with significant physical dysfunction who require rehabilitation to reduce disability.

Treating pediatric patients often invokes discomfort and anxiety among emergency medical service (EMS) personnel. As part of the process to improve pediatric care in the prehospital system, the Health Resources and Services Administration (HRSA) Emergency Services for Children (EMSC) Program implemented two prehospital performance measures -access to a designated pediatric care coordinator (PECC) and skill evaluation using pediatric equipment-along with a multi-year plan to aid states in achieving the measures. Baseline data from a survey conducted in 2017 showed that less than 25% of EMS agencies had access to PECC and 47% performed skills evaluation using pediatric equipment at least twice a year. To evaluate change over time, the survey was again conducted in 2020, and agencies that participated in both years are compared.

A web-based survey was sent to EMS agency administrators in 58 states and territories from January to March 2020. Descriptive statistics, odds ratios, and 95% confidence intervals were conducted.
