Abstract
OBJECTIVES Effective health communication can increase intent to vaccinate. We compared 8 messages that may influence parents' intent to vaccinate their children against COVID-19. METHODS In a cross-sectional survey of adults in the United States administered online in August 2021, 1837 parents and legal guardians were exposed to 8 messages (individual choice, gain/practical benefits, nonexpert, health care provider recommendation, altruism/community good, safety/effectiveness, safety, and effectiveness) to determine message reception and influence on intent to vaccinate their children. Parents responded to 10 questions using a Likert scale. We computed odds ratios (ORs) for each message, with an OR >1.0 indicating greater observed odds of participant agreement with the follow-up statement as compared with a reference message. We compared outcomes individually across messages with ordinal logistic regression fit using generalized estimating equations. RESULTS The individual choice message had the highest odds of agreement for understanding intent (OR = 2.10; 95% CI, 1.94-2.27), followed by the health care provider recommendation message (OR = 1.58; 95% CI, 1.46-1.71). The individual choice message had the highest odds of memorability, relatability, and trustworthiness. The altruism/community good message was at or near second best. The altruism/community good message had the highest or near-highest odds of increasing parents' intent to vaccinate their children, asking friends and family for their thoughts, and searching for additional information. The message that most motivated parents to vaccinate their children depended on parental intent to vaccinate prior to being exposed to the tested messages. CONCLUSIONS Messages with themes of individual choice, health care provider recommendation, and altruism/community good may be used in future message campaigns. Further research is needed to refine message concepts related to altruism/community good.

Strengthening COVID-19 vaccine confidence & demand during the US COVID-19 emergency response. Vaccine 2024:S0264-410X(24)00029-X. [PMID: 38267329 DOI: 10.1016/j.vaccine.2024.01.029] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 12/14/2023] [Accepted: 01/09/2024] [Indexed: 01/26/2024]
Abstract
In October 2020, the CDC's Vaccinate with Confidence strategy specific to COVID-19 vaccines rollout was published. Adapted from an existing vaccine confidence framework for childhood immunization, the Vaccinate with Confidence strategy for COVID-19 aimed to improve vaccine confidence, demand, and uptake of COVID-19 vaccines in the US. The objectives for COVID-19 were to 1. build trust, 2. empower healthcare personnel, and 3. engage communities and individuals. This strategy was implemented through a dedicated unit, the Vaccine Confidence and Demand (VCD) team, which collected behavioral insights; developed and disseminated toolkits and best practices in collaboration with partners; and collaborated with health departments and community-based organizations to engage communities and individuals in behavioral interventions to strengthen vaccine demand and increase COVID-19 vaccine uptake. The VCD team collected and used social and behavioral data through establishing the Insights Unit, implementing rapid community assessments, and conducting national surveys. To strengthen capacity at state and local levels, the VCD utilized "Bootcamps," a rapid training of trainers on vaccine confidence and demand, "Confidence Consults", where local leaders could request tailored advice to address local vaccine confidence challenges from subject matter experts, and utilized surge staffing to embed "Vaccine Demand Strategists" in state and local public health agencies. In addition, collaborations with Prevention Research Centers, the Institute of Museum and Library Services, and the American Psychological Association furthered work in behavioral science, community engagement, and health equity. The VCD team operationalized CDC's COVID-19 Vaccine with Confidence strategy through behavioral insights, capacity building opportunities, and collaborations to improve COVID-19 vaccine confidence, demand, and uptake in the US. The inclusion of applied behavioral science approaches were a critical component of the COVID-19 vaccination program and provides lessons learned for how behavioral science can be integrated in future emergency responses.

COVID-19 Vaccine Hesitancy Among US Adults: Safety and Effectiveness Perceptions and Messaging to Increase Vaccine Confidence and Intent to Vaccinate. Public Health Rep 2024; 139:102-111. [PMID: 37924246 PMCID: PMC10905758 DOI: 10.1177/00333549231204419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/06/2023] Open
Abstract
OBJECTIVE Public health agencies have a critical role in providing effective messaging about mitigation strategies during a public health emergency. The objectives of this study were (1) to understand perceptions of COVID-19 vaccines, including concerns about side effects, safety, and effectiveness and how these perceptions influence vaccine decision-making among US adults and (2) to learn what messages might motivate vaccine uptake. METHODS In April and May 2021, we conducted 14 online focus groups with non-Hispanic English-speaking and English- and Spanish-speaking Hispanic adults (N = 99) not vaccinated against COVID-19. We oversampled adults aged 18-39 years and rural residents and systematically assessed 10 test messages. Researchers used a standardized guide and an a priori codebook for focus group discussions, coding transcripts, and thematic analysis. RESULTS Vaccine hesitancy factors included fear of the unknown; long-term side effects, including infertility; and beliefs that the vaccines were developed too quickly and were not sufficiently effective. Motivating factors for receiving vaccination included the ability to safely socialize and travel. Health care providers were considered important trusted messengers. Participants were critical of most messages tested. Messages that came across as "honest" about what is not yet known about COVID-19 vaccines were perceived more positively than other messages tested. Messages were seen as ineffective if perceived as vague or lacking in data and specificity. CONCLUSIONS Messages that were simple and transparent about what is unknown about vaccines relative to emerging science were viewed most favorably. Health care providers, friends, and family were considered influential in vaccination decision-making. Findings underscore the benefits of research-informed strategies for developing and disseminating effective messages addressing critical issues in a public health emergency.

Abstract
BACKGROUND Induced pluripotent stem cell (iPSC)-derived cell therapies are an interesting new area in the field of regenerative medicine. One of the approaches to decrease the costs of iPSC-derived therapies is the use of allogenic homozygous human leukocyte antigen (HLA)-matched donors to generate iPSC lines and to build a clinical-grade iPSC bank covering a high percentage of the Spanish population. METHODS The Spanish Stem Cell Transplantation Registry was screened for cord blood units (CBUs) homozygous for the most common HLA-A, HLA-B and HLA-DRB1 haplotypes. Seven donors were selected with haplotypes covering 21.37% of the haplotypes of the Spanish population. CD34-positive hematopoietic progenitors were isolated from the mononuclear cell fraction of frozen cord blood units from each donor by density gradient centrifugation and further by immune magnetic labeling and separation using purification columns. Purified CD34 + cells were reprogrammed to iPSCs by transduction with the CTS CytoTune-iPS 2.1 Sendai Reprogramming Kit. RESULTS The iPSCs generated from the 7 donors were expanded, characterized, banked and registered. Master cell banks (MCBs) and working cell banks (WCBs) from the iPSCs of each donor were produced under GMP conditions in qualified clean rooms. CONCLUSIONS Here, we present the first clinical-grade, iPSC haplobank in Spain made from CD34 + cells from seven cord blood units homozygous for the most common HLA-A, HLA-B and HLA-DRB1 haplotypes within the Spanish population. We describe their generation by transduction with Sendai viral vectors and their GMP-compliant expansion and banking. These haplolines will constitute starting materials for advanced therapy medicinal product development (ATMP).

Abstract
An attenuated SARS-CoV-2 virus with modified viral transcriptional regulatory sequences and deletion of open-reading frames 3, 6, 7 and 8 (∆3678) was previously reported to protect hamsters from SARS-CoV-2 infection and transmission. Here we report that a single-dose intranasal vaccination of ∆3678 protects K18-hACE2 mice from wild-type or variant SARS-CoV-2 challenge. Compared with wild-type virus infection, the ∆3678 vaccination induces equivalent or higher levels of lung and systemic T cell, B cell, IgA, and IgG responses. The results suggest ∆3678 as an attractive mucosal vaccine candidate to boost pulmonary immunity against SARS-CoV-2.

Abstract
Coronal holes are areas on the Sun with open magnetic field lines. They are a source region of the solar wind, but how the wind emerges from coronal holes is not known. We observed a coronal hole using the Extreme Ultraviolet Imager on the Solar Orbiter spacecraft. We identified jets on scales of a few hundred kilometers, which last 20 to 100 seconds and reach speeds of ~100 kilometers per second. The jets are powered by magnetic reconnection and have kinetic energy in the picoflare range. They are intermittent but widespread within the observed coronal hole. We suggest that such picoflare jets could produce enough high-temperature plasma to sustain the solar wind and that the wind emerges from coronal holes as a highly intermittent outflow at small scales.

Abstract
Magnetic reconnection is a key mechanism involved in solar eruptions and is also a prime possibility to heat the low corona to millions of degrees. Here, we present ultra-high-resolution extreme ultraviolet observations of persistent null-point reconnection in the corona at a scale of about 390 km over one hour observations of the Extreme-Ultraviolet Imager on board Solar Orbiter spacecraft. The observations show formation of a null-point configuration above a minor positive polarity embedded within a region of dominant negative polarity near a sunspot. The gentle phase of the persistent null-point reconnection is evidenced by sustained point-like high-temperature plasma (about 10 MK) near the null-point and constant outflow blobs not only along the outer spine but also along the fan surface. The blobs appear at a higher frequency than previously observed with an average velocity of about 80 km s-1 and life-times of about 40 s. The null-point reconnection also occurs explosively but only for 4 minutes, its coupling with a mini-filament eruption generates a spiral jet. These results suggest that magnetic reconnection, at previously unresolved scales, proceeds continually in a gentle and/or explosive way to persistently transfer mass and energy to the overlying corona.

Abstract
OBJECTIVES The main objective of this study was to analyze French general practitioners' (GP) online prescriptions for suspected acute cystitis using a single nationwide teleconsultation platform. PATIENTS AND METHODS First, a descriptive study of management for suspected cystitis was conducted from the 1st of January to the 31st of December 2020. After which, following pedagogical intervention, a pre/post descriptive analysis of the antibiotics prescribed was carried out. RESULTS Some 496,041 teleconsultations (TCs) were carried out in 2020 on the Qare platform. Among them, 15089 TCs for cystitis with ICD-10 encoding (N30) were analyzed. Fosfomycin trometamol was the most prescribed antibiotic (n=10297, 69%), while fluoroquinolones (n=1568, 10.6%) were the second. Urine test strip was prescribed in 3157 (20%) and urine culture in 7033 (47%) of the TCs. July-August 2020 and July-August 2021 were compared and while a significant drop in fluoroquinolone prescriptions and a major increase in Fosfomycin trometamol were observed, there was no change in the prescriptions of urine culture. An average antibiotic conformity rate of 61.5% was observed before the intervention, and 68.8% afterwards. CONCLUSIONS Cystitis is a recurrent reason for remote consultation. The study demonstrated sizable over-prescription of urine culture, ultrasound, and fluoroquinolones. Intervention should be improved and strengthened to guarantee continuous training and awareness of GP's on appropriate cystitis prescriptions in telemedicine.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted global public health safety and the economy. Multiple antiviral drugs have been developed, and some have received regulatory approval and/or authorization. The use of nutraceuticals can be beneficial for preventing and treating COVID-19 complications. AHCC is a standardized, cultured extract of an edible mushroom Lentinula edodes of the Basidiomycete family of fungi that is enriched in acylated α-1,4-glucans. Here, we evaluated the effects of the oral administration of AHCC on the host response to SARS-CoV-2 infection in two murine models, K18-hACE2 transgenic mice and immunocompetent BALB/c mice. Oral administration of AHCC every other day for one week before and one day post SARS-CoV-2 infection in both strains of mice decreased the viral load and attenuated inflammation in the lungs. AHCC treatment also significantly reduced SARS-CoV-2-induced lethality in the K18-hACE2 mice. AHCC administration enhanced the expansion of γδ T cells in the spleen and lungs before and after viral infection and promoted T helper 1-prone mucosal and systemic T cell responses in both models. In AHCC-fed BALB/c mice, SARS-CoV-2 specific IgG responses were also enhanced. In summary, AHCC supplementation enhances host resistance against mild and severe COVID-19 infection primarily via the promotion of innate and adaptive T cell immune responses in mice.

Abstract
Introduction The COVID-19 pandemic generated a health emergency and led to the adoption of different measures, including home quarantine and social isolation, which, as we have seen, has had an impact on the mental health of the majority of citizens, with the possibility of psychiatric disorders appearing. in people without prior mental illness, such as acute decompensations in patients with known disorders, more vulnerable to environmental stressors. Objectives Learn and rethink alarm signals in extreme situations such as the one experienced in recent months, as well as observe the impact, negative in many cases, but positive in others, of the patients we treat daily. Methods Description through brief clinical cases of the impact of the COVID-19 pandemic on psychotic patients and the decompensation that it has entailed, including due to confinement measures and social isolation, associated with over-information through the media, chaos initial and the uncertainty that it caused and the associated fear. Results Restrictions as a result of COVID-19 have played a very relevant role as an external stressor for the appearance of psychopathological alterations, including psychotic symptoms. In addition, people who suffer from psychosis or at risk of psychotic disorder can be especially affected and trigger acute psychopathology with social isolation, loss of daily routines, unemployment, homelessness. Conclusions These cases are an example that shows the need for an early and effective approach to the rise in mental illnesses in circumstances of this caliber.

Abstract
BackgroundNon-alcoholic fatty liver disease (NAFLD), the most common cause of liver disease, has a prevalence of about 25% in the general population. It increases mortality and comorbidity in patients with immune-mediated inflammatory diseases.ObjectivesThe main objective is to estimate the prevalence of NAFLD in three of the most common rheumatologic pathologies: rheumatoid arthritis (RA), axial spondyloarthritis (SpA-ax) and psoriatic arthritis (PsA). As a secondary objective, the possibility of finding associated risk factors in this group of subjects that may imply a higher risk of developing NAFLD is proposed.MethodsWe conducted a prospective single center observational study which included patients diagnosed with RA, EspA-ax, and PsA attended in the Rheumatology department of a tertiary hospital from January to April 2021. Anthropometric parameters, history related to cardiovascular risk factors and disease activity at the time of the visit were collected. Additionally, blood tests and transitional elastography were performed in all patients and the presence of NAFLD was assessed by the fatty liver index (FLI) scale. Different variables were considered to study their association with NAFLD.Results90 patients were included: 28 diagnosed with RA, 36 with EspA-ax and 26 with PAs. 41.1% were male (age range: 27-79 years). Patients with previous liver disease were excluded from the study. 22 (27.2%) patients had NAFLD measured by FLI ≥ 60. No significant differences in prevalence of hepatic steatosis were found between the 3 groups, although values were higher in patients with PsA.The variables that were significantly associated with the development of NAFLD in our cohort were: body mass index (BMI), abdominal perimeter, blood glucose level, HOMA-IR (Homeostatic Model Assessment for Insulin Resistance), HDL, TG, GGT, ferritin and uric acid levels. The rest of the variables studied did not show statistically significant differences (Table 1).Table 1.NO STEATOSIS (FLI<60)n=59STEATOSIS (FLI>60)n=22MeanStandard deviationMeanStandard deviationpBMI24,523,0030,292,77< 0,001Abdominal perimeter86,3410,01106,828,55< 0,001Age52,9312,8757,598,240,1185Glucose78,648,3790,6419,690,0002Insulin8,8310,1212,406,660,1302HOMA1,752,022,761,700,0500HbA1c5,350,455,690,640,0096Total cholesterol190,9829,46201,4138,530,1977HDL64,8817,6655,5911,550,0249LDL110,4428,45120,0036,210,2163TG81,1232,42128,5055,52< 0,001GPT25,8330,7337,1819,820,1116GOT27,2023,4926,8210,690,9413GGT20,8017,6649,9538,46< 0,001Creatinin0,750,190,840,180,0583Uric acid4,781,305,911,140,0007Ferritina121,75111,30208,00140,170,0050PCR2,894,552,672,330,8307ConclusionHepatic steatosis was present in 27.2% of patients vs 25% estimated prevalence in the general population. Identification of risk factors involved would allow better control of the comorbidities associated with NAFLD.The fact that the prevalence found in our sample population is so close to that of the general population, may be related to a good inflammatory control of the underlying disease.Further prospective studies with larger sample sizes are needed to find additional predictive factors for the development of NAFLD in this group of diseases.References[1]Bedogni, G., Bellentani, S., Miglioli, L., Masutti, F., Passalacqua, M., Castiglione, A. y Tiribelli, C.

Abstract
Background: Smell and taste disorders are reported very frequently and at an early stage in SARS-CoV-2 infectious disease. These symptoms could be sensitive and specific to establish possible severity of the infection, and may suggest the flow of decisions as to further therapy. Objective: We asked whether smell and taste impairment are earlier and more sensitive symptoms than the RT-PCR molecular assays for SARS-CoV-2 detection. Methods: Subjects (N=275) with a probable COVID-19 diagnosis were classified as follows: Symptomatic with chemosensory dysfunction, symptomatic without chemosensory dysfunction, and asymptomatic. Validated unbiased testing of the chemosensory dysfunction was performed by means of the Venezuelan Olfactory Test and taste test. Nasal swabs and blood samples were analyzed by RT-PCR molecular analysis a rapid diagnostic test to detect the SARS-CoV-2 virus and viral antibodies, respectively. Smell and taste testing and RT-PCR were performed every 3 to 5 days to patients until full recovery. Results: Out of 144 patients that were positive for SARS-CoV-2: 45.83% had COVID-19 symptoms, smell and taste disorders; 23.61% had COVID-19 symptoms but not smell or taste disorders, and 30.55% were asymptomatic. Mild hyposmia and hypogeusia were frequently associated with SARS-CoV-2 symptoms. Recovery from chemosensory dysfunction occurred between day 3 and 14. RT-PCR becomes negative after 21 days. The Venezuelan Olfactory Test and taste test has a 61.68% positive predictive value, 45.83% sensitivity, and 68.7% specificity for SARS-CoV-2. Conclusions: Smell and taste disorders are associated symptoms with SARS-CoV-2 infection, but not a predictor of the disease, as compared to the molecular RT-PCR test.

Abstract
BACKGROUND Limited information is available regarding the risk of incident liver disease in patients with psoriasis receiving systemic therapies. OBJECTIVES To describe the liver safety findings of conventional and modern systemic therapies for moderate-to-severe psoriasis, and to compare the relative incidence rates of hepatic adverse events (AEs) for each drug. METHODS All the patients on the BIOBADADERM registry were included. Crude and adjusted incidence rate ratios (cIRR and aIRR, respectively) of hepatic AEs, using anti-TNF drugs as reference, were determined. Outcomes of interest were hypertransaminasemia, nonalcoholic fatty liver disease (NADFLD) and a group of other, less represented, hepatic AEs. RESULTS Our study included 3,171 patients exposed to systemic drugs (6279 treatment cycles). Incident hypertransaminasemia was the most frequent hepatic AE (incidence rate of 21 per 1000 patients-years [CI 95% CI 18-23]), followed by NAFLD (8 cases per 1000 patients-years [95% CI 6-10]). Methotrexate (aIRR 3.06 [2.31-4.4]; p = 0.000) and cyclosporine (aIRR 2.37 [1.05-5.35]; p = 0.0378) were associated with an increased risk for hypertransaminasemia when compared to anti-TNF-α agents. No differences were observed between different groups of biologics. Conventional therapies were not associated with new incident NAFLD. CONCLUSIONS Comparative information of the incidence of hepatic AEs could facilitate drug selection in moderate-to-severe psoriasis.

Abstract
Introduction Cyberchondria involves excessive and uncontrollable online searching of information about a perceived illness. This behavior can cause or maintain distress. Objectives Little is known about cyberchondria during the COVID-19 pandemic or how cyberchondria in one individual may cause distress in their significant other if they are self-isolating together; our study sought to fill these gaps. Methods We conducted a Qualtrics Panel survey with 760 cohabitating Canadian couples; in June 2020, participants retrospectively reported on their cyberchondria behavior, general anxiety, and COVID-19 fears during the month of April 2020, while adhering to stay-at-home advisories. Two separate actor-partner interdependence models (APIMs) used cyberchondria excessiveness and compulsion to predict generalized anxiety and COVID-19 danger/contamination fears in the actor and partner. Results Both cyberchondria excessiveness and compulsion were associated with higher general anxiety and higher COVID-19 danger/contamination fears in the individual (actor effects). Partner cyberchondria compulsion was associated with higher general anxiety in the individual whereas partner cyberchondria excessiveness was associated with higher COVID-19 danger/contamination fears in the individual (partner effects). Conclusions Findings suggest that excessive and uncontrollable searching of information about COVID-19 on the internet during lockdown may contribute to distress in both the individual engaging in the cyberchondria behavior, and in their romantic partner. Moreover, different aspects of cyberchondria in the partner (compulsion vs. excessiveness) appears to contribute to general vs. COVID-19-specific anxiety/fears in the partner, respectively. Future research should examine mechanisms underlying the observed partner effects (e.g., co-rumination, social contagion) and reasons for the differential partner effects of cyberchondria components.

Abstract
As the number of people living with undiagnosed HIV infection in the UK declines, innovative ways to access those least engaged with services are needed. This study explores the attitudes of men who have sex with men (MSM) towards using HIV self-testing (HIVST) kits distributed via a vending machine in a sauna (a licenced sex-on-premise venue). Twenty-three MSM attending the sauna were recruited to take part in semi-structured qualitative interviews. The participants were overwhelmingly positive about the HIVST vending machine. They identified convenience and flexibility as major benefits to testing in this way. The sauna was felt to be an appropriate location for the intervention. Limitations identified included the potential to reduce screening for other sexually transmitted infections and the inappropriate use of HIVST kits as a tool for risk-assessment prior to condomless sex, with a poor understanding of the window period. The implications of receiving a positive result without immediate access to support were also a concern. HIVST vending machines are an acceptable, innovative way to encourage HIV testing. Providers need to ensure this intervention is supported by adequate information regarding the limitations of the test and how to access comprehensive services to avoid any unintended negative effects.

Abstract
Prostaglandin E2 (PGE2) is an important mediator of cellular responses, playing a key role in limiting inflammation. PGE2 acts distinctly through one of four EP receptors. In MSCs, it PGE2 stimulation of EP2 and EP4 receptors triggers processes such as migration, self-renewal, survival, and proliferation, and their activation is involved in homing. PGE2 has been proposed as a key factor of MSC immunomodulation. The CRISPR-Cas9 system has been adapted successfully to edit the genome of animals. Loss of EP2 and EP4 receptors in equine adipose mesenchymal stem cells (eAT-MSC) could help us understand their role in cell migration, homing, and self-renewal capacities. Here, we aimed to edit these receptors in eAT-MSC to test their function. The eAT-MSC were obtained from three Chilean breed horses and cultured in Dulbecco's modified Eagle's medium-high glucose with 10% fetal bovine serum. Guide RNAs (sgRNA) for CRISPR-Cas 9 editing were designed based on EP2 and EP4 DNA sequences. The sgRNA and PAM sequence targeting exon 1 of the equine genes (EP2-sgRNA: TGGTGCTGGCTTCGTACGCG; PAM:CGG and EP4-sgRNA: GGAGACGACCTTCTACACGT;PAM:TGG) were cloned into linearized LentiCRISPRv2GFP vector (#82416; Addgene). The lentiviral vector plus helping packaging plasmids was co-transfected into HEK293FT cells. The produced viral particles were harvested and transduced into eAT-MSC. After 48h, cells were sorted and green fluorescent protein (GFP)-positive cells were expanded to obtain individual clones. Genomic DNA was extracted for PCR amplification, and the frequency of site directed-mutation was assessed by T7 endonuclease assay. Because of the high background (e.g. excessive banding) produced by the T7E1 assay, the PCR products were cloned into a pUC57 vector, and sequenced. Quantitative PCR and immunocytochemistry staining examined expression of EP2 and EP4. The statistical analyses were performed using GraphPad Prism 6 (GraphPad Inc.) with unpaired t-test; P-values<0.05 were considered statistically significant. Transduction efficiency of eAT-MSC/EP2ko and eAT-MSC/EP4ko was 31 and 38%, respectively. A total of 15 clones for each lineage obtained from a single cell culture were subjected to T7EI assay to identify the frequency of mutation. Eight eAT-MSC/EP2ko and 7 eAT-MSC/EP4ko clones showed mutations; DNA sequencing confirmed mutations in 3 eAT-MSC/EP2ko clones and 3 eAT-MSC/EP4ko clones. Immunostaining with specific anti-EP2 and anti-EP4 antibodies showed diminished expression of the particular receptors in the knockout cells. Decreased expression was quantitatively confirmed by quantitative PCR analysis, showing downregulation of PTGER2 (4.3-fold) and PTGER4 (2.7-fold) in the edited clones compared with eAT-MSC naïve cells (P<0.05). This CRISPR/Cas9 design allows the possibility of using these mutant cell lines as a model system to elucidate the role of EP2 and EP4 in cell migration, homing, and self-renewal.

Abstract
Abstract
Background
There is scarce evidence about the prevalence and clinical relevance of moderate to severe valvular heart disease (VHD) in survivors of out of hospital cardiac arrest (OHCA).
Purpose
To determine whether VHD influence prognosis of OHCA survivors.
Methods
All consecutive patients admitted to the Acute Cardiac Care Unit after OHCA and surviving until hospital discharge were included. All patients received targeted-temperature management according to our local protocol. Univariate and multivariate Cox-proportional hazard models were employed.
Results
A total of 201 patients were included in the analysis. Mean age was 57.6±14.2 years and 168 (83.6%) were male. Eighteen patients (9.0%) had moderate or severe VHD during index admission (Table 1). Patients with VHD were less frequently of male sex, [11 (61.1%) vs 157 (85.8%), p=0.014], experienced less acute coronary syndrome-related arrhytmias [2 (11.1%) vs 85 (46.5%), p=0.005], and had a lower pH at hospital admission (6.9±1.6 vs 7.2±0.15, p=0.008). During a median follow-up of 40.3 (18.9–69.1) months, patients with VHD showed higher mortality [7 (38.9%) vs 28 (15.3%), p=0.004] and more heart failure-related admissions [7 (38.9%) vs 15 (8.2%), p<0.001]. Only five patients received surgical or percutaneous treatment for VHD during follow-up, with no deaths in this subgroup. Moderate or severe VHD proved to be an independent predictor of global cardiovascular events and specifically heart failure episodes (Figure 1).
Table1 Variable With valvular disease Without valvular disease p value Age, mean±DS, years 63.5±13.2 57.0±14.1 0.066 Hypertension, n (%) 12 (66.7) 95 (51.9) 0.231 Diabetes, n (%) 5 (27.8) 24 (13.1) 0.149 Dyslipidaemia, n (%) 7 (38.9) 79 (43.2) 0.726 Smokin habit, n (%) 4 (22.2) 90 (49.2) 0.045 Witnessed cardiac arrest, n (%) 18 (100) 175 (95.6) 1.000 Time from CA to ROSC, mean±DS, minute 19.1±7.5 21.2±13.1 0.506 Shockable rhythm, n (%) 13 (72.2) 163 (89.1) 0.055 LVEF at hospital discharge (%) 42.8±12.1 46.9±14.6 0.254
Figure 1
Conclusion
The presence of significant VHD in survivors after OHCA is a predictor of poor outcomes. Specific management of VHD may be specially relevant in this high-risk patients and guideline-oriented therapy, including surgery and percutaneous intervention should be encouraged when indicated.

Abstract
Abstract
Background
Platelet/lymphocyte ratio (PLR), an inflammatory marker associated with poor outcomes in different clinical situations, may play a role in the proinflammatory state triggered during hypoxic-ischemic brain injury secondary to cardiac arrest.
Purpose
To study PLR dynamics and its relationship with neurologic outcomes in survivors after CA treated with target-temperature-management (TTM).
Methods
Observational retrospective study from a prospective database of survivors of in-hospital and out-of-hospital CA admitted to our Acute Cardiac Care Unit between August 2006 to December 2018. All patients received TTM according to our local protocol.
Results
A total of 466 patients were included. Mean age was 62.7±14.4 years and 102 (21.9%) were women. Baseline characteristics are shown in Table 1. 430 (92.2%) of CA were witnessed, 312 (67.0%) had ventricular fibrillation as initial cardiac rhythm. Among them, 236 (51.1%) survived until hospital discharge and 208 (45.1%) presented favorable neurological outcomes (a score 1 or 2 on cerebral performance category (CPC)). The mean value of PLR at admission and during targeted temperature was 100.4±5.2 and 224.5±7.3 respectively (mean difference 123.1±7.1, p<0.0001). This increase in PLR was significantly higher among patients with worse neurological outcomes (CPC 3–5, mean DPLR 138.2±5.5) at 3 months compared with survivors with CPC 1–2 (mean DPLR 108.2±6.3, p=0.0348 for paired comparison between both groups).
Table 1 Hypertension, n (%) 235 (54.9) Diabetes, n (%) 113 (26.4) Dyslipidaemia, n (%) 171 (40.0) Smocking habit, n (%) 208 (48.5) Time to ROSC mean ± SD, min 26.6±18.6 Mean arterial pressure at HA mean±DS, mmHg 81.3±22.1 pH at HA mean ± SD 7.18±0.16 Lactic at HA mean ± SD 6.37±4.42 ROSC: return of spontaneus circulation; HA: hospital admission.
Conclusion
Our findings reflect the impact of inflammation in neurological outcomes after OHCA treated with TTM. Major increases of PLR constitute a novel marker of poor prognosis during early assessment of OHCA patients.

Abstract
Prostaglandin E2 (PGE2) acts through 4 cellular receptors: EP1, EP2, EP3, and EP4; only EP2 and EP4 are relevant for immunomodulation and migration in immune cells. Besides those, several cells express these receptors on their surface, including mesenchymal stem cells. Pharmacological inhibition of the EP2 receptor prevents migration of immune system cells to inflamed sites, where the concentration of PGE2 is high. Based on this, we hypothesised that overexpression of EP2 or EP4 receptors in equine mesenchymal stem cells (eMSC) will improve their migration to inflammatory sites and subsequent homing capability. Conversely, their suppression will lead to low or no migration, favouring the paracrine properties of MSC in the processes of tissue regeneration and reduction of inflammation. To test this, we manipulated the PGE2-EP2-EP4 axis and evaluated the effect of such modifications on transgenic cells in vitro. Equine MSC from adipose tissue were obtained from 5 animals. The coding sequences of both receptors were synthesised (GenScript, Hong Kong) based on the published horse genome (National Center for Biotechnology Information; https://www.ncbi.nlm.nih.gov/) and cloned into pcDNA3.1 overexpression vectors (Addgene). The resulting constructs were lipofected into naïve adipose eMSC. For knockouts, we PCR-amplified and sequenced horse EP2 and EP4 receptors, and gRNAs were created based on the obtained sequences and ligated into LentiCRISPRV2 plasmid (Addgene, Cambridge, MA, USA). The lentiviral vector plus helping packaging plasmids were co-transfected into HEK293FT cells and the produced viral particles were harvested and transduced into adipose eMSC. After 48h of transfection (for overexpression) or transduction (for knockout, KO), cells were probed for the presence/absence of EP2 and EP4 receptors by immunohistochemistry and/or quantitative (q)PCR. Mitomycin-C-treated cells of both phenotypes and naïve, were subjected to migration in scratch assay, towards 3mM PGE2. Fetal calf serum (10 or 0%) was used as positive or negative control, respectively, in migration experiments. Receptors EP2 and EP4 were clearly overexpressed after transfection as determined by immunocytochemistry or qPCR assays (phenotype MSC-EP2+/EP4+), whereas in the cells that underwent KO, little or no expression of EP2 and EP4 was detected (phenotype MSC-EP2ko/EP4ko) compared with unmanipulated cells (naïve MSC-Ctr). In the migration experiments towards 3mM of PGE2, MSC-EP2+/EP4+ cells at 24h filled the scratch faster (P<0.05) than MSC-EP2ko/EP4ko or MSC-Ctr. These results showed that manipulation of PGE2-EP2/EP4 axis receptors led to changes in cell surface receptor availability and increased the migration pattern in overexpressed cells compared with KO and unmanipulated cells. These factors may affect the design of cellular therapeutic tools for inflammatory diseases in the equine species.

Understanding barriers and predictors of maternal immunization: Identifying gaps through an exploratory literature review. Vaccine 2018; 36:7445-7455. [PMID: 30377064 PMCID: PMC10431095 DOI: 10.1016/j.vaccine.2018.10.046] [Citation(s) in RCA: 63] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2018] [Revised: 10/05/2018] [Accepted: 10/10/2018] [Indexed: 01/05/2023]
Abstract
BACKGROUND The Advisory Committee for Immunization Practices recommends that all pregnant women receive the seasonal influenza vaccine and the tetanus toxoid, diphtheria toxoid, and acellular pertussis (Tdap) vaccine during every pregnancy. However, vaccination coverage rates are suboptimal among pregnant women in the United States, leaving these women and their unborn children at risk of vaccine-preventable diseases and their complications. OBJECTIVES We sought to understand the current landscape of published literature regarding maternal immunization, including barriers to and predictors of vaccine acceptance, and identify gaps in the research in order to inform strategies for future programmatic improvement. METHODS We conducted a literature search using MEDLINE (OVID), PsychINFO, and CINAHL (Ebsco) databases. The search included published, English-language manuscripts that identified patient, provider, or system-level barriers to, predictors of, or interventions that improved uptake of maternal vaccines among pregnant women in the US. Studies were reviewed using an inductive thematic analysis approach. RESULTS We included 75 studies in our review. Pregnant women identified 25 different barriers to accepting recommended maternal immunizations; barriers related to vaccine safety perceptions were the most common. Healthcare providers identified 24 different barriers to vaccinating their pregnant patients. The most commonly cited barriers among healthcare providers were financial concerns. Eighteen different predictors of vaccine acceptance were identified. Receipt of a healthcare provider's recommendation was the factor most frequently reported as a reason for vaccination among pregnant women. CONCLUSIONS We were able to identify gaps in the literature regarding maternal immunization and make recommendations for future research. Efforts to address the challenges of maternal immunization in the United States should include increasing the focus on Tdap, implementing more high-level assessments of safety perceptions and associated concerns, and determining most effective interventions.

Abstract
This policy statement, which is the sixth of a series of documents prepared by the Asia-Oceania Federation of Organizations for Medical Physics (AFOMP) Professional Development Committee, gives guidance on how medical physicists in AFOMP countries should conduct themselves in an ethical manner in their professional practice (Ng et al. in Australas Phys Eng Sci Med 32:175-179, 2009; Round et al. in Australas Phys Eng Sci Med 33:7-10, 2010; Round et al. in Australas Phys Eng Sci Med 34:303-307, 2011; Round et al. in Australas Phys Eng Sci Med 35:393-398, 2012; Round et al. in Australas Phys Eng Sci Med 38:217-221, 2015). It was developed after the ethics policies and codes of conducts of several medical physics societies and other professional organisations were studied. The policy was adopted at the Annual General Meeting of AFOMP held in Jaipur, India, in November 2017.

Abstract
OBJECTIVES The first-passage adherent human bone marrow fibroblast-like cell population corresponds, in terms of phenotype and three-lineage differentiation capacity (assayed in bulk culture), to commonly termed "mesenchymal stem cells". Here we determine the proportion of high proliferative capacity multipotent cells present in this population in order to estimate the proportion of cells that can or cannot be considered as stem and progenitor cells. MATERIAL AND METHODS The single-cell cultures were established starting from human bone marrow-derived first-passage fibroblast-like cells and the proliferating clones were either transferred to secondary cultures to evaluate their further clonogenicity, or split into three wells to assess differentiation into each of the three different lineages. RESULTS The analysis of 197 single-cell cultures from three different bone marrow donors shows that only∼40% of so-called "mesenchymal stem cells" exhibit multipotency and are capable of sustained clonogenicity in secondary cultures. CONCLUSION Even in the first ex vivo passage under favorable conditions the majority (∼60%) of so-called "mesenchymal stem cells" are not multipotent and thus do not represent a stem cell entity.

Provider insight on surmounting specialty practice challenges to improve Tdap immunization rates among pregnant women. Heliyon 2018; 4:e00636.

Abstract
BACKGROUND Pertussis, or "whooping cough," is an acute, contagious pulmonary disease that, despite being vaccine-preventable, has become an increasingly widespread problem in the United States. As a result, the Advisory Committee on Immunization Practices and American College of Obstetricians and Gynecologists updated recommendations stating clinicians should give a Tdap dose during every pregnancy, preferably at 27-36 weeks. Despite this recommendation, reported Tdap vaccine receipt rates during pregnancy vary from 16-61%, and previous studies have shown that clinician recommendation and vaccine administration are strongly associated with vaccine uptake among pregnant women. METHODS Our aim was to inform new strategies to increase uptake of the Tdap vaccine among pregnant women and, ultimately, reduce pertussis-related morbidity and mortality in infants. We conducted interviews with a sample of 24 ob-gyns. We subsequently performed grounded theory analyses of transcripts using deductive and inductive coding strategies followed by intercoder reliability assessment. RESULTS All physicians interviewed were familiar with the most recent recommendation of giving the Tdap vaccine during the third trimester of every pregnancy, and the majority of physicians stated that they felt that the vaccine was important and effective due to the transfer of pertussis antibodies from the mother to the fetus. Most physicians indicated that they recommended the vaccine to patients during pregnancy, but not all reported administering it on site because it was not stocked at their practice. Implementation challenges for physicians included insurance reimbursement and other challenges (i.e., patient refusal). Tdap vaccination during pregnancy was a lower clinical priority for some physicians. Physicians recognized the benefits associated with Tdap vaccination during pregnancy. CONCLUSIONS Findings indicate while most ob-gyns recognize the benefits of Tdap and recommend vaccination during pregnancy, barriers such as insurance reimbursement and financial concerns for the practice can outweigh the perceived benefits. This resulted in some ob-gyns reporting choosing not to stock and administer the vaccine in their practice. Recommendations to address these concerns include 1) structural support for Tdap vaccine administration in ob-gyns practices; 2) Continuing medical education-equivalent educational interventions that address management techniques, vaccine coding, and other relevant information; and 3) interventions to assist physicians in communicating the importance of Tdap vaccination during pregnancy.
