Endocrine, Stemness, Proliferative, and Proteolytic Properties of Alarm Cells in Ruby-Red-Fin Shark (Rainbow Shark), Epalzeorhynchos frenatum (Teleostei: Cyprinidae)

Abstract Abstract The current study investigated the morphological, histochemical, and immunohistochemical characteristics of alarm cells and their precursors in ruby-red-fin shark (rainbow shark), Epalzeorhynchos frenatum (Teleostei: Cyprinidae). Precursor alarm cells were shown to be small, cuboidal, pyramidal, or round in shape, with eosinophilic cytoplasm, resting on the basement membrane of the epidermis. The cells later elongated to become columnar in shape. Subsequently, they enlarged and became large oval-shaped cells. They then underwent shrinkage and vacuolation. The superficial alarm cells were collapsed. Alarm cells were found to have an affinity for different histochemical stains, including bromophenol blue, iron hematoxylin, Sudan black, Mallory triple trichrome, Crossman's trichrome, Safranin O, and Weigert's stains, as well as lipase and alkaline phosphatase. Endocrine properties of the alarm cells were identified by silver staining and synaptophysin immunostaining. Alarm cells exhibited stemness activities and had a strong immunoaffinity for CD117. They had a proteolytic function, as identified by lysosome-specific staining with acridine orange and strong immunoaffinity for matrix metalloproteinase (MMP-9). They also exhibited proliferatively, reflected by immunological staining by proliferating cell nuclear antigen. In conclusion, alarm cells are unique epidermal cells with multiple functions. They play immunological, and endocrine, roles. They also retain stemness and proliferative properties.
Willingness and influential factors of parents of 3-6-year-old children to vaccinate their children with the COVID-19 vaccine in China

ABSTRACT The impact of Coronavirus disease 2019 (COVID-19) on children aged 3–6 can be severe. Vaccination for COVID-19 is one of the most important primary preventative measures to reduce disease transmission. Parents are hesitant to vaccinate their children against COVID-19 because it was reported in the news that some adults have had adverse reactions to the vaccine. This study aims to investigate the willingness of Chinese parents of 3–6 year old children to vaccinate them with the COVID-19 vaccine and identify what factors influence their decisions. A survey was conducted using a two-stage stratified random sampling method from December 2020 to February 2021. We used univariate analysis and multivariate binary logistic analysis to explore potential factors that may determine the acceptance of the COVID-19 vaccine. Of the 468 parents who participated, 86.75% were willing to vaccinate their children with the COVID-19 vaccine. Parents who were female (OR = 2.591; 95% CI: 0.432–4.689), recognized their children in the high-risk category (OR = 2.494; 95% CI:1.244–5.002), often followed-up with COVID-19 vaccine-related information (OR = 9.065; 95% CI: 3.220–28.654), believed in the safety of the COVID-19 vaccine (OR = 3.068; 95% CI: 1.313–7.168), or thought the COVID-19 vaccine could prevent COVID-19 (OR = 13.750; 95% CI: 2.516–75.140) were more willing to vaccinate their children. To ease parents’ hesitation about vaccines, the authority organization should release updated information on the safety and reliability of vaccines, target gender-specific health education for parents, and ask the media to report scientifically support information.
Knowledge, attitudes, and practices for the use of seasonal influenza vaccination, healthcare workers, Costa Rica

Introduction: Annual seasonal influenza vaccination in healthcare workers prevents nosocomial transmission to patients, coworkers, and visitors, and reduces absenteeism. This study aimed to describe knowledge, attitudes, and practices (KAP) of seasonal influenza vaccine among public healthcare workers attending patients in Costa Rica. Methodology: We conducted a cross-sectional survey of healthcare personnel attending patients in public hospitals in 2017–2018. Frequency distributions of demographics, vaccination KAP, sources of information, clinical manifestations and reasons for non-vaccination were reported. Logistic regression was used to analyze associations between exposures of interest (demographics, sources of information, knowledge, attitudes towards vaccination) and self-reported influenza vaccination. Results: We surveyed 747 healthcare workers in 2017–2018. Of 706 participants who knew their vaccination status, 55.7% were vaccinated for seasonal influenza. Only 20.7% of participants knew the influenza vaccine was an inactivated virus, and 94.6% believed the vaccine causes flu-like symptoms. Factors associated with current influenza vaccination were vaccination in previous year (aOR: 8.13; 95% CI: 5.65–11.71) and believed influenza vaccination may be harmful (aOR: 0.62; 95% CI: 0.44–0.89). Reasons for non-vaccination included fear of adverse effects and access limitations. Conclusions: Suboptimal influenza vaccination among healthcare workers may be attributed to misconceptions about the vaccine and limited engagement strategies focusing on healthcare workers. Appropriate interventions are needed to increase healthcare worker vaccination rates and improve their knowledge and beneficence, which would improve patient safety in hospitals.
Mild matters: parental insights into the conundrums of managing mild congenital hearing loss

Abstract Objective To explore and describe parental experiences related to the management of mild bilateral congenital hearing loss in children. Design Using qualitative methods, we conducted semi-structured interviews with parents/caregivers until saturation of themes was achieved. We analysed transcripts using inductive content analysis. Study sample Caregivers of children under 3-years-old with mild bilateral sensorineural hearing loss. Results We interviewed 12 parents. Parental perception of advice regarding hearing aid fitting was varied; almost all children were offered hearing aids. Perceived positives related to hearing aids: feeling empowered that action has been taken; improvements in the child’s hearing perception and; facilitation of behavioural management. Perceived negatives of hearing aid use: difficulties with compliance resulting in parental frustration and guilt, damage/loss of equipment, discomfort, parental discord, altered quality of natural sound and potential bullying/stigma. Some parents were ambivalent about the effect of the hearing aids. Where hearing aids were offered and not fitted, there was significant ongoing uncertainty, and the family carried the burden of their decision. Conclusions There was a wide variation in perceived advice regarding early hearing aid fitting in children with mild bilateral hearing loss. We identified parental perceptions of positive/negative impacts of hearing aid fitting and potential perceived harms from not fitting.
Forecasting COVID-19 Hospital Census: A Multivariate Time-Series Model Based on Local Infection Incidence

Background COVID-19 has been one of the most serious global health crises in world history. During the pandemic, health care systems require accurate forecasts for key resources to guide preparation for patient surges. Forecasting the COVID-19 hospital census is among the most important planning decisions to ensure adequate staffing, number of beds, intensive care units, and vital equipment. Objective The goal of this study was to explore the potential utility of local COVID-19 infection incidence data in developing a forecasting model for the COVID-19 hospital census. Methods The study data comprised aggregated daily COVID-19 hospital census data across 11 Atrium Health hospitals plus a virtual hospital in the greater Charlotte metropolitan area of North Carolina, as well as the total daily infection incidence across the same region during the May 15 to December 5, 2020, period. Cross-correlations between hospital census and local infection incidence lagging up to 21 days were computed. A multivariate time-series framework, called the vector error correction model (VECM), was used to simultaneously incorporate both time series and account for their possible long-run relationship. Hypothesis tests and model diagnostics were performed to test for the long-run relationship and examine model goodness of fit. The 7-days-ahead forecast performance was measured by mean absolute percentage error (MAPE), with time-series cross-validation. The forecast performance was also compared with an autoregressive integrated moving average (ARIMA) model in the same cross-validation time frame. Based on different scenarios of the pandemic, the fitted model was leveraged to produce 60-days-ahead forecasts. Results The cross-correlations were uniformly high, falling between 0.7 and 0.8. There was sufficient evidence that the two time series have a stable long-run relationship at the . 01 significance level. The model had very good fit to the data. The out-of-sample MAPE had a median of 5.9% and a 95th percentile of 13.4%. In comparison, the MAPE of the ARIMA had a median of 6.6% and a 95th percentile of 14.3%. Scenario-based 60-days-ahead forecasts exhibited concave trajectories with peaks lagging 2 to 3 weeks later than the peak infection incidence. In the worst-case scenario, the COVID-19 hospital census can reach a peak over 3 times greater than the peak observed during the second wave. Conclusions When used in the VECM framework, the local COVID-19 infection incidence can be an effective leading indicator to predict the COVID-19 hospital census. The VECM model had a very good 7-days-ahead forecast performance and outperformed the traditional ARIMA model. Leveraging the relationship between the two time series, the model can produce realistic 60-days-ahead scenario-based projections, which can inform health care systems about the peak timing and volume of the hospital census for long-term planning purposes.
What Works (or Does Not) in Community Risk Management for Persons Convicted of Sexual Offenses? A Contemporary Perspective

Contemporary data from the United States show that rates of sexual offending and reoffending have been in steady decline for decades. Nonetheless, nonprofessionals continue to view sexual violence as a community safety issue fraught with risk and uncertainty. The past 30 years have been witness to considerable research and practice in the assessment, treatment, and risk management of persons who have sexually offended. Gains have also been made in regard to prevention and citizen education. Modern day technologies include actuarial risk assessment instruments, measures of criminogenic need and treatment progress, refinements to treatment processes, and the establishment of evidence-based models. Legislative authorities in the United States and elsewhere have also attempted to affect risk in the community with, perhaps, lesser degrees of success. This article reviews current policies and practices, with a specific focus on what happens when offenders are released to the community (e.g., how public policies intended to track offenders and/or restrict their movements can negatively affect community reintegration). Comprehensive approaches to community sexual offender management are examined in addition to suggestions of unique approaches intended to ensure citizen buy-in and engagement.
The Psychological Experience of Frontline Perioperative Health Care Staff in Responding to COVID-19: Qualitative Study

Background The rapid spread of the novel coronavirus (COVID-19) has presented immeasurable challenges to health care workers who remain at the frontline of the pandemic. A rapidly evolving body of literature has quantitatively demonstrated significant psychological impacts of the pandemic on health care workers. However, little is known about the lived experience of the pandemic for frontline medical staff. Objective This study aimed to explore the qualitative experience of perioperative staff from a large trauma hospital in Melbourne, Australia. Methods Inductive thematic analysis using a critical realist approach was used to analyze data from 9 semistructured interviews. Results Four key themes were identified. Hospital preparedness related to the perceived readiness of the hospital to respond to the pandemic and encompassed key subthemes around communication of policy changes, team leadership, and resource availability. Perceptions of readiness contributed to the perceived psychological impacts of the pandemic, which were highly varied and ranged from anger to anxiety. A number of coping strategies were identified in response to psychological impacts which incorporated both internal and external coping mechanisms. Finally, adaptation with time reflected change and growth over time, and encompassed all other themes. Conclusions While frontline staff and hospitals have rapidly marshalled a response to managing the virus, relatively less consideration was seen regarding staff mental health in our study. Findings highlight the vulnerability of health care workers in response to the pandemic and reinforce the need for a coordinated approach to managing mental health.
Clinical and functional results of radiofrequency ablation and microwave ablation in patients with benign thyroid nodules

Objectives: To determine how well ultrasound-guidance percutaneous radiofrequency ablation (RFA) and microwave ablation (MWA) performed for benign symptomatic thyroid nodules in terms of clinical and functional outcomes. Methods: Patients who had a thyroid nodule-linked symptoms acting as dysphagia, cosmetic issues, pain, a foreign body sense, hyperthyroidism secondary to autonomous nodules, or concern of malignancy were involved in the study. The primary was the comparison in symptom scores obtained at 1, 3, and 6 months after RFA and MWA. The volume alterations in nodules and alterations in thyroid gland functions were secondary objectives. Results: This prospective study carried out from November 2014 and January 2017 at the General Surgery Department, Marmara University, Faculty of Medicine, Istanbul, Turkey included a total of 100 nodules (50% MWA, 50% RFA). There were statistically significance in pain scores, dysphagia scores, and foreign body sensation scores at 1, 3, and 6 months after therapy in both ablation groups (p=0.0006, p=00004, p=0.0005). At the same time, there were statistically significant reductions in size and volume of the nodules for RFA and MWA (p=0.0004, p=0.0003). There was no significant difference between the RFA and MWA groups’ cosmetic scoring and volume changes (p=0.68, p=0.43). Conclusions: Alternative therapies for benign symptomatic thyroid nodules include RFA and MWA. The findings of this research revealed that both approaches are safe and effective.
Analysis of primary care prescription trends in England during the COVID-19 pandemic compared against a predictive model

Objectives The COVID-19 pandemic has had an unprecedented impact across primary care. Primary care services have seen an upheaval, and more and more patients are engaging in telephone consultations in order to maintain social distancing. In the present study, we seek to quantify the effect of the pandemic on primary care prescribing. Design We conducted a retrospective analysis of the English Prescribing Dataset from January 2014 to November 2020, totalling 7 542 293 921 prescriptions. Data were separated into prepandemic and pandemic sets. A Holt-Winters predictive model was used to forecast individual drug prescribing based on historic trends. Observed data were compared with the forecast quantitatively and qualitatively. Setting All prescriptions signed in England and dispensed during the years 2014–2020. Participants All residents of England who received a prescription from primary care facilities during 2014–2020. Results Prescribing of numerous health-critical medications was above predicted in March 2020, including salbutamol (53.0% (99% CI (41.2% to 66.9%))), insulin aspart (26.9% (99% CI (18.5% to 36.6%))) and tacrolimus (18.6% (99% CI (8.3% to 31.1%))). Medications for end-of-life symptom control increased in April, including levomepromazine hydrochloride (94.7% (99% CI (54.6% to 163.0%))). Medications requiring face-to-face visits decreased, including the local anaesthetic bupivacaine hydrochloride (86.6% (99% CI (89.3% to 82.0%))). There was no observed change in medications relating to type 2 diabetes, hypertension or mental health conditions. Conclusions Significantly increased prescribing of several medications was observed, especially among those critical for health. A dramatic spike in end-of-life prescribing highlights the adversity faced by community practitioners during 2020. Medications involving face-to-face consultations declined, as did contraceptives, travel-related vaccines and drugs used in dementia and Parkinson’s disease. Drugs relating to type 2 diabetes, hypertension and mental health were unchanged.
Direct admission vs. secondary transfer for mechanical thrombectomy: long-term clinical outcomes from a single Polish Comprehensive Stroke Centre.

INTRODUCTION We aimed to compare 3-month clinical outcomes after mechanical thrombectomy (MT) in patients transferred directly to a comprehensive stroke centre ('mothership', MS) to the outcomes of patients transferred secondarily from primary stroke centres ('drip-and-ship', DAS) in Lubelskie province, the third largest province in Poland. MATERIALS AND METHODS In a prospective stroke registry, all patients with large vessel occlusion in anterior circulation admitted within six hours of onset and treated with MT between 2017 and 2020 were retrospectively analysed. RESULTS A total of 400 patients was evaluated: 267 treated with the MS approach and 133 with the DAS approach. Time from stroke onset to groin puncture was shorter in the MS group. There was a significant difference in 3-month excellent clinical outcomes (mRS 0-1) between these two groups (32.9% of MS patients vs. 22.5% of DAS patients, p < 0.05), but there was no difference if the 3-month endpoint was expressed as mRS ≤ 2 (42.3% of MS vs. 34.5% of DAS patients, p = 0.13). The rate of symptomatic intracranial haemorrhage and mortality was comparable in both groups. CONCLUSIONS Our study shows that direct admission to a comprehensive stroke centre resulted in more patients achieving excellent treatment outcomes (mRS 0-1). At the same time, the superiority of the MT model over the DAS model in obtaining mRS 0-2 was not unequivocally demonstrated. Further studies are needed to determine the best stroke model for patients potentially eligible for MT.
Pine fresh: the cultural and medical context of pine scent in relation to health—from the forest to the home

Pine is a familiar scent in domestic cleaning products, but how often do we relate it to its origins as an odour emanating from a tree? This article takes a sensory history approach to trace the late 19th century and early 20th century use of the pine forest as a therapeutic space, via the tuberculosis sanatoria to the use of pine scent in domestic disinfectant. By focusing on pine as experienced in this period as a microhistorical subject, this methodology will in turn allow for a detailed consideration of how historical context, and in particular medical conceptions and health concerns, can influence the creation of cultural memory. By following the trajectory of pine from its place in the forest to a commercial product used in the home, this will allow for an investigation at the intersection of environmental and medical histories and provide a framework for the consideration of the relationship of place to senses associated with concepts of health and well-being. As interest grows in the development of more effective sensory settings, in particular within healthcare, it also highlights the importance of considering the roles both cultural and personal memory play in response to various sensory stimuli.
Physical inactivity and its predictors among adolescents in Saudi Arabia

Objectives: To estimate the prevalence of insufficient physical activity and excessive screen time among adolescents living in cities participating in the Healthy Cities Program (HCP) and cities not running the program in the Qassim region of Saudi Arabia. Methods: We surveyed 1133 adolescents from the Qassim region using systematic random sampling between April and September 2017. Multivariable logistic regression analyses were conducted to investigate the predictors of insufficient levels of PA and excessive screen time. Results: The prevalence of <60 minutes of moderate- to vigorous-intensity physical activity/day was 82.4% and <3 days of vigorous intensity physical activity/week among adolescents was 59%. There was no significant association between living in healthy cities (HCPs) and insufficient levels of physical activity. The odds of excessive screen time were higher in HCPs than in cities not running the program (NHCPs) (OR: 1.49). The odds of insufficient daily PA (OR: 2.19) are higher among girls than boys. Increasing age is positively associated with insufficient weekly PA (OR: 1.19). The prevalence of excessive recreational screen time is 84.6% with higher odds in HCPs than in NHCPs (OR: 1.51). Conclusion: Our findings report a lack of evidence of any impact of the HCP on adolescents’ physical activity behaviors. This outcome warrants a further in-depth evaluation of the process and outcomes of the HCP in Saudi Arabia.
Mouse papillomavirus type 1 (MmuPV1) DNA is frequently integrated in benign tumors by microhomology-mediated end-joining

MmuPV1 is a useful model for studying papillomavirus-induced tumorigenesis. We used RNA-seq to look for chimeric RNAs that map to both MmuPV1 and host genomes. In tumor tissues, a higher proportion of total viral reads were virus-host chimeric junction reads (CJRs) (1.9‰ - 7‰) than in tumor-free tissues (0.6‰ - 1.3‰): most CJRs mapped to the viral E2/E4 region. Although most of the MmuPV1 integration sites were mapped to intergenic regions and introns throughout the mouse genome, integrations were seen more than once in several genes: Malat1, Krt1, Krt10, Fabp5, Pard3, and Grip1; these data were confirmed by rapid amplification of cDNA ends (RACE)-Single Molecule Real-Time (SMRT)-seq or targeted DNA-seq. Microhomology sequences were frequently seen at host-virus DNA junctions. MmuPV1 infection and integration affected the expression of host genes. We found that factors for DNA double-stranded break repair and microhomology-mediated end-joining (MMEJ), such as H2ax, Fen1, DNA polymerase Polθ, Cdk1, and Plk1, exhibited a step-wise increase and Mdc1 a decrease in expression in MmuPV1-infected tissues and MmuPV1 tumors relative to normal tissues. Increased expression of mitotic kinases CDK1 and PLK1 appears to be correlated with CtIP phosphorylation in MmuPV1 tumors, suggesting a role for MMEJ-mediated DNA joining in the MmuPV1 integration events that are associated with MmuPV1-induced progression of tumors.
