Abstract
Background It is well-known that frequent nature visits are associated with health benefits in children. Global climate crisis and environmental challenges emphasize the need for reconnecting children to nature, as well. Young children’s nature connectedness (NC) involves enjoyment of nature, sense of responsibility, empathy, and awareness of nature. The study examines whether there is an association between the frequency of parent-child nature visits and young children’s NC. Methods The study uses WEB survey data from the Finnish Empowered by Nature project. Respondents, n = 1463, were parents of children aged 2 to 7 years old. NC was assessed by 11-items derived from the NC questionnaire of Sobko et al (2018). Multinomial logistic regression analysis was used and the lowest tertile of NC was used as reference group. Analysis were adjusted for child’s age and gender, and highest education of parent. Results Children with moderate (1-2 times a week in previous month) or high (3 times a week or more) frequency of parent-child nature visits were more likely to have strong than weak NC compared to children with low frequency (less than once a week) of adult-child nature visits. Odds ratios (OR) in adjusted models were: moderate frequency 1.67 (1.21- 2.32), and high frequency 2.31 (1.67-3.18). The odds of having medium NC compared to weak NC were more likely in moderate frequency compared to low frequency of parent-child nature visits in the adjusted model (OR 1.46; 1.07-2.00). Conclusions The results highlight the importance of parents visiting nature frequently with their children during early childhood. It promotes young children’s NC and may further contribute to raising environmentally responsible children. Key messages • More frequent parent-child visits promote young children’s nature connectedness which involves enjoyment of nature, sense of responsibility, empathy, and awareness of nature. • A strong nature connectedness among children is highly relevant, as it may contribute to raise environmentally responsible children.

Abstract
Background Outdoor education (OE) is a teaching method aiming to promote children’s learning, physical activity (PA) and wellbeing. OE in green areas may further increase positive effects. There is little knowledge on use of OE and its possible effects in a Finnish context. Also, there is a need to evaluate OE from a teacher perspective. The aim of the LärMiljö-study is to: a) survey the use of OE in Swedish-language primary schools and investigate factors related to its use; b) investigate the associations between OE and PA, wellbeing, nature relations and learning among children aged 9-13 years, considering other related factors. Methods The self-determination theory (SDT) is used as theoretical framework. Data is collected via electronic surveys in Swedish-language primary schools, including: a) national surveys among principals and teachers; b) surveys among children and guardians. Children’s PA is measured for a 7-day period via accelerometers and a diary is kept. Teachers keep a class diary on OE provided. Academic tests are performed. Data will be analyzed using quantitative methods. Results This abstract describes the study protocol. The investigation of associations between OE and outcomes among children is mainly done by comparing classes that regularly use OE with classes that do not. Main outcomes are PA, psychosocial wellbeing, academic performance and nature connectedness; secondary outcomes are school motivation, social relations and sleep. Teachers’ experience and use of OE is explored, as is perceived effects of and barriers to OE use. Based on SDT, associations between OE and need satisfaction at work, competence, motivation and work engagement are studied. Conclusions The study represents a unique opportunity to explore OE use in primary schools, its effects among children and teachers, and what the supporting and hindering factors for its use are. The study contributes knowledge that can be used to promote learning and wellbeing in school. Key messages • Outdoor education in primary school may promote schoolchildren’s learning, physical activity, wellbeing and nature relation, but more knowledge is needed, including the perspective of teachers. • The LärMiljö-study will broaden the understanding of the potential effects of OE in primary education and school health promotion, and on factors supporting and hindering its use.

Added value of Joint ENT-Rheumatology clinic in the management of ANCA-associated vasculitis: One year's experience. Am J Otolaryngol 2022; 43:103485. [PMID: 35567837 DOI: 10.1016/j.amjoto.2022.103485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Accepted: 05/01/2022] [Indexed: 11/01/2022]
Abstract
PURPOSE ANCA-associated vasculitides (AAV) represent a group of diagnoses, including granulomatosis with polyangiitis (GPA), eosinophilic granulomatosis with polyangiitis (EGPA) and microscopic polyangiitis (MPA). Most commonly, they present initially with ENT-associated symptomatology, and therefore they often pose a diagnostic challenge. We aim to present our one-year experience in the joint management of AAV in a multi-disciplinary setting. METHODS We performed a retrospective analysis based on the records of 39 patients who were seen in the joint clinic, during a period of one year. RESULTS After clinical assessment, 13 patients had changes made to their ENT treatment, 2 had some changes in their immunosuppression, while 11 had changes in both ENT and Rheumatology treatment. Six patients did not require any alterations to their therapeutic scheme. On average three separate appointments were reduced to a single appointment in the joint clinic where definitive treatment decisions were made. This led to significant cost reductions. CONCLUSIONS Cost-effectiveness, patient satisfaction, rapid multi-disciplinary evaluation, avoidance of unnecessary immunosuppression, patient education and medical training are only a few of the many advantages of this proposed joint service.

Abstract
OBJECTIVES To determine whether it was feasible to use a haemorrhage assessment tool (HAT) within a trauma trial and whether the data obtained could differentiate patients who had achieved haemostasis. BACKGROUND Major haemorrhage is one of the leading causes of death worldwide, affecting 40% of trauma patients. Clinical trials evaluating haemostatic interventions often use transfusion outcomes as a primary endpoint. Transfusion is highly dependent on local practice, limiting its reliability as a robust, transferable endpoint. METHODS A five-point HAT questionnaire was applied to participants enrolled into the EFIT-1 trial. This RCT evaluated the feasibility of administering a 6 g fibrinogen concentrate to patients with severe trauma haemorrhage. RESULTS Of participants, 98% completed a HAT; 75% participants had 'achieved haemostasis' at the time of tool completion, as determined by clinical acumen alone. HAT scores were able to differentiate which participants required transfusion after 3 h. Of participants, 56% were transfused red blood cells when they scored 0-2, compared to 17% with HAT scores between 3 and 5. CONCLUSION This study has confirmed the feasibility of using a HAT during the emergency care of patients suffering trauma haemorrhage, and future studies should be conducted to determine its value as an endpoint in haemostasis studies.

Abstract
INTRODUCTION Pharmacological salicylates are known to trigger respiratory exacerbations in patients with Non-Steroidal Exacerbated Respiratory Disease (N-ERD), a specific phenotype of Chronic Rhinosinusitis (CRS) and asthma. The impact of dietary sources of salicylates across subgroups of CRS is not well understood. The hypothesis is that in patients with nasal polyps present, there is likely to be a higher incidence of symptom exacerbation due to dietary salicylates regardless of any known response to pharmacological salicylate. METHODS The Chronic Rhinosinusitis Epidemiology Study (CRES) was a questionnaire-based case-control study which sought to characterise the UK CRS population in terms of sociological, economic and medical factors. Using specific questions to examine participant responses relating to symptom exacerbation from food groups thought to be high in salicylate content, this analysis of the CRES database sought to compare an estimate of the prevalence of dietary sensitivity due to food with higher potential salicylate content across patients with CRS with (CRSwNPs) and without nasal polyposis (CRSsNPs) and with allergic fungal rhinosinusitis (AFRS). RESULTS The CRSwNPs group were significantly more likely than controls to report symptom exacerbation due to ingestion of food groups with higher potential dietary salicylate content. The same trend was observed amongst CRSsNPs participants to a lesser degree. Reported response to the individual specific food groups wine, nuts, spicy foods, fruit and vegetables demonstrated that a statistically significant proportion of CRSwNPs and AFRS participants reported sensitivity to wine. CONCLUSIONS This analysis suggests that there is an association between symptom exacerbation in response to food products with higher potential salicylate content, specifically wine, in CRS patients both with and without nasal polyposis when compared to controls, but especially in the CRSwNPs and AFRS phenotypes. Further studies are needed to detail if this relationship represents a causal relationship to dietary salicylate. The data present the possibility that a wider group of CRS patients may elicit salicylate sensitivity than those with known N-ERD.

Abstract
BACKGROUND Prostate cancer is an extremely heterogeneous disease. Despite being clinically similar, some tumours are more likely to recur after surgery compared to others. Distinguishing those that need adjuvant or salvage radiotherapy will improve patient outcomes. The goal of this study was to identify circulating microRNA that could independently predict prostate cancer patient risk stratification after radical prostatectomy. METHODS Seventy-eight prostate cancer patients were recruited at the Odette Cancer Centre in Sunnybrook Health Sciences Centre. All patients had previously undergone radical prostatectomy. Blood samples were collected simultaneously for PSA testing and miRNA analysis using NanoString nCounter technology. Of the 78 samples, 75 had acceptable miRNA quantity and quality. Patients were stratified into high- and low-risk categories based on Gleason score, pathological T stage, surgical margin status, and diagnostic PSA: patients with Gleason ≥ 8; pT3a and positive margin; pT3b and any margin; or diagnostic PSA > 20 µg/mL were classified as high-risk (n = 44) and all other patients were classified as low-risk (n = 31). RESULTS Using our patient dataset, we identified a four-miRNA signature (miR-17, miR-20a, miR-20b, miR-106a) that can distinguish high- and low-risk patients, in addition to their pathological tumour stage. High expression of these miRNAs is associated with shorter time to biochemical recurrence in the TCGA dataset. These miRNAs confer an aggressive phenotype upon overexpression in vitro. CONCLUSIONS This proof-of-principle report highlights the potential of circulating miRNAs to independently predict risk stratification of prostate cancer patients after radical prostatectomy.

Abstract
BACKGROUND The differential diagnosis for pediatric prepubertal vaginal bleeding is wide. Rare etiologies include vascular malformations and tumors, such as infantile hemangiomas (IHs), which validate the usefulness of exam under anesthesia, vaginoscopy, and tissue diagnosis. CASE We report a case of an IH in a 6-year-old girl causing vaginal bleeding requiring transfusion. Vaginoscopy revealed a cervical IH of less than 1 cm. Expectant management and oral propranolol were successful management options. SUMMARY AND CONCLUSION Rare, even small soft tissue tumors such as IH can lead to impressive blood loss via vaginal bleeding. Accurate tissue diagnosis and a multidisciplinary approach are essential to planning safe, effective treatment, and follow-up.

Abstract
The key factors to consider when designing microwave absorber materials for eradication of electromagnetic (EM) pollution are absorption of incident EM waves and good impedance matching. By keeping these things in mind, flexible microwave absorber composite films can be fabricated by simple gel casting techniques using reduced graphene oxide (RGO) and strontium ferrite (SF) in a poly(methyl methacrylate) (PMMA) matrix. SF nanoparticles are synthesized by the well known sol-gel method. Subsequently, reduced graphene oxide (RGO) and SF nanocomposite (RGOSF) are prepared through a chemical reduction method using hydrazine. The structure, morphology, chemical composition, thermal stability and magnetic properties of the nanocomposite are characterized in detail by various techniques. The SF particles are found to be nearly 500 nm and decorated on RGO sheets as revealed by field emission scanning electron microscopy and transmission electron microscopy analysis. Fourier transform infrared and and Raman spectroscopy clearly show the presence of SF in the graphene sheet by the lower peak positions. Finally, ternary polymer composites of RGO/SF/PMMA are prepared by an in situ polymerization method. Magnetic and dielectric studies of the composite reveal that the presence of RGO/SF/PMMA lead to polarization effects contributing to dielectric loss. Also, RGO surrounding SF provides a conductive network in the polymer matrix which is in turn responsible for the magnetic loss in the composite. Thus, the permittivity as well as the permeability of the composite can be controlled by an appropriate combination of RGO and SF in PMMA. More than 99% absorption efficiency is achieved by a suitable combination of magneto-dielectric coupling in the X-band frequency range by incorporating 9 wt% of RGO and 1 wt% of SF in the polymer matrix.

Abstract
The effects of establishing a full multidisciplinary community psychiatric team in central London are described. The nature of referrals, and referrers' satisfaction with the service were examined during two comparable six-month periods, before and after the changes. The number and severity of referrals increased, and referrers were more satisfied with the new service. In contrast to the inter-agency model, the new multidisciplinary team was associated with more appropriate referral of those patients with the greatest need for specialist services. Clinical skill mix in the team and referrer education are the two factors most likely to have promoted these important changes. The key role of the psychiatrist in a full multidisciplinary team who can empower multi-professional case managers in their day-to-day management of severely ill patients is highlighted.

Abstract
Higher surgical training in the UK faces a cut of two years. We conducted a questionnaire survey to assess the operative experience of current higher surgical trainees in otological surgery and the likely effect of the proposed reduction from six to four years. 91 (65%) of the 142 higher surgical trainees responded with details of major otological procedures performed (independently or assisting) over one year. In the present six-year scheme a typical trainee performs 72 myringoplasties, 79 mastoidectomies, 7 skull base procedures and 28 other procedures. In the first four years, however, his or her experience is only 39 myringoplasties, 44 mastoidectomies, 4 skull base procedures and 7 others. The large shortfall in experience that might result from shortening of the training programme would need to be met by intensification of the training or institution of accredited otology fellowships. Very similar dilemmas are faced by other surgical specialties.

Abstract
Prevention of tick-borne diseases requires an understanding of when and where exposure to ticks is most likely. We used an epidemiologic approach to define these parameters for residents of a Lyme-endemic region. Two persons in each of 500 Connecticut households were asked to complete a log each night for one week during June, 2013. Participants recorded their whereabouts in 15min increments (indoors, outdoors in their yard, outdoors on others' private property, or outdoors in public spaces) and noted each day whether they found a tick on themselves. Demographic and household information was also collected. Logs were completed for 934 participants in 471 households yielding 51,895 time-place observations. Median participant age was 49 years (range 2-91 years); 52% were female. Ninety-one participants (9.8%) reported finding a tick during the week, with slightly higher rates among females and minors. Household factors positively associated with finding a tick included having indoor/outdoor pets (odds ratio (OR)=1.7; 95% confidence interval (CI): 1.1-2.9), the presence of a bird feeder in the yard (OR=1.9; CI:1.2-3.2), and presence of an outdoor dining area (OR=2.2; CI:1.1-4.3). Individual factors associated with finding a tick on a given day were bathing or showering (OR=3.7; CI:1.3-10.3) and hours spent in one's own yard (OR=1.2, CI:1.1-1.3). Nineteen participants found ticks on multiple days, more than expected assuming independence (p<0.001). Participants who found ticks on multiple days did not spend more time outdoors but were significantly more likely to be male than those finding ticks on a single day (p<0.03). Our findings suggest that most tick exposures in the study area occurred on private property controlled by the respective homeowner. Interventions that target private yards are a logical focus for prevention efforts.

Abstract
Premise and Objective: Elective laparoscopic cholecystectomy (LC) has low risk for post-operative infectious complications; still most clinicians use persistent post-operative prophylactic antibiotics out of habit, tradition, or simply as defensive practice due to evolving medicolegal implications of a large number of surgeries being showcased as daycare or next day discharge procedures. This randomised prospective trial was done to test the need for such prophylaxis in cases of elective LC in a rural/semi-urban setting. Materials and Methods: Two hundred and ten successive patients undergoing elective LC were randomised into groups receiving single dose of injection ceftriaxone at the time of induction of anaesthesia, (Group A = 112 cases) and those who in addition to above received injection ceftriaxone twice daily for 2 days postoperatively (Group B = 98 cases). Post-operative infectious complications between two groups were compared for variables such as age, sex, body mass index and bile/stone spillage. Results: There was no significant difference in surgical site infection rates between the groups for variables such as age, sex, body mass index, duration of symptoms, American Society of Anesthesiologists grade, duration of surgery and hospital stay. Intraoperative spillage of stones (9.8% [A]: 5.1% [B]) did not increase infectious complications even in the presence of positive bile culture (Group A, N = 7 vs. Group B, N = 3). An operative time of greater than 60 min was found to be associated with increased surgical site infection (P = 0. 0006). Conclusion: Single dose of ceftriaxone at the time of induction is adequate prophylaxis following elective LC even in the rural/semi-urban Indian setting and routine continued administration of antibiotic should be abandoned as it contributes to adverse reactions, drug resistance and unnecessary financial burden.

Abstract
Polyphenols can exert both, antioxidant and pro-oxidant properties, depending on cell types as well as their concentrations. Hence, it was of interest to examine if the naturally occurring resveratrol analog, trans-4,4'-dihydroxystilbene (DHS) also exert both these activities in a biphasic or cell-specific manner. In this study, we established the cytoprotective action of DHS against hydrogen peroxide (H2O2)-induced apoptotic death of the PC12 cells. DHS reduced mitochondrial membrane permeabilization and deactivated reactive oxygen species (ROS)-mediated caspase-3 activation in the H2O2-treated PC12 cells. However, it induced apoptosis in the human neuroblastoma SHSY-5Y cell line by destabilizing mitochondrial membrane, augmenting ROS and activating caspapse-3. DHS showed better activity than resveratrol in both the chosen models.

Abstract
Cell communications are essential to the organization, development, and maintenance of multicellular organisms. Much of this communication involves changes in RNA transcription and is dynamic. Most methods for studying transcription require interrupting the continuity of cellular function by sacrificing the communicating cells and capturing gene expression information by periodic sampling of individual cells or the population. The IMAGEtag technology to quantify RNA levels in living cells, demonstrated here in yeast, allows individual cells to be tracked over time as they respond to different environmental cues. IMAGEtags are short RNAs consisting of strings of a variable number of tandem aptamers that bind small-molecule ligands. The aptamer strings can vary in length and in configuration of aptamer constituents, such as to contain multiples of the same aptamer or two or more different aptamers that alternate in their occurrence. A minimum effective length is about five aptamers. The maximum length is undefined. The small-molecule ligands are enabled for imaging as fluorophore conjugates. For each IMAGEtag, two fluorophore conjugates are provided, which are FRET pairs. When a cell expresses an RNA containing an IMAGEtag sequence, the aptamers bind their ligands and bring the fluorophores into sufficiently close proximity to allow FRET. The background fluorescence of both fluorophores is minimal in the FRET channel. These features endow IMAGEtags with the sensitivity to report on mRNA expression levels in living cells.

Abstract
A search for a narrow Higgs boson resonance in the diphoton mass spectrum is presented based on data corresponding to 7.0 fb{-1} of integrated luminosity from pp collisions at sqrt[s]=1.96 TeV collected by the CDF experiment. No evidence of such a resonance is observed, and upper limits are set on the cross section times branching ratio of the resonant state as a function of Higgs boson mass. The limits are interpreted in the context of the standard model and one fermiophobic benchmark model where the data exclude fermiophobic Higgs bosons with masses below 114 GeV/c{2} at a 95% Bayesian credibility level.

Abstract
Terrorist attacks using an aerosolized pathogen have gained credibility as a national security concern after the anthrax attacks of 2001. Inferring some important details of the attack quickly, for example, the number of people infected, the time of infection, and a representative dose received can be crucial to planning a medical response. We use a Bayesian approach, based on a short time series of diagnosed patients, to estimate a joint probability density for these parameters. We first test the formulation with idealized cases and then apply it to realistic scenarios, including the Sverdlovsk anthrax outbreak of 1979. We also use simulated outbreaks to explore the impact of model error, as when the model used for generating simulated epidemic curves does not match the model subsequently used to characterize the attack. We find that in all cases except for the smallest attacks (fewer than 100 infected people), 3-5 days of data are sufficient to characterize the outbreak to a specificity that is useful for directing an emergency response.

Abstract
INTRODUCTION Despite the important advances observed in the last 25 years in the comprehension of the clinical and biological nature of breast cancer and its treatment, this disease remains a significant cause of cancer morbidity and mortality worldwide. The clinical trial Hera has demonstrated the safety and efficacy of trastuzumab in the treatment of HER2 positive (HER2+) breast cancer patients, in early stages, subsequent to surgery, chemotherapy (neoadjuvante or adjuvant) and radiotherapy, if applied. OBJECTIVES To evaluate the cost-effectiveness of 1-year trastuzumab treatment versus standard care (observation following standard adjuvant chemotherapy), in patients with HER2+ breast cancer in early stages from the societal and the Portuguese National Health Service (NHS) perspectives. METHODS A 5-state Markov model with annual transition cycles was developed to estimate the long term health and economic outcomes of HER2+ early breast cáncer patients based on HERA clinical trial results. Portuguese NHS resource use and costs were estimated from a consensus expert panel and published unit costs, respectively. Clinical and economic outcomes were discounted at 3% per annum. The incremental cost-effectiveness ratios per life year gained (LYG) and per quality adjusted life year (QALY) gained were estimated. One-way sensitivity analysis was performed. RESULTS Considering a 45 year time horizon, treatment with trastuzumab was estimated to increase discounted life expectancy by 2,114 life years and quality-adjusted life expectancy by 2,009 QALYs compared to standard care. Direct and indirect costs were projected to be 61.839 euro and 19.759 euro with trastuzumab and 40.559 euro and 25.392 euro with standard of care. These results corresponded to incremental cost-effectiveness ratios of 10.067 euro and 10.595 euro assuming direct costs only, and of 7.400 euro and 7.789 euro including indirect costs, per life year gained and per QALY gained, respectively. CONCLUSIONS The 1-year trastuzumab use as adjuvant therapy in HER-2+ early breast cancer patients improves survival and can be considered a cost effective therapy with a high degree of certainty in the Portuguese setting.

Abstract
The objective was to test a hypothesized genetic component (i.e., monozygotic being more similar compared with dizygotic twins) in dental fear/anxiety by comparing the probandwise concordance. We analyzed data based on a dichotomous measure of Dental Fear/Anxiety and a continuous measure of Dental Fear Intensity from over 2000 twins, collected when participants were 13-14 years old and once again three years later. The hypothesis was confirmed, but heritability of Dental Fear/Anxiety was estimated to be higher for girls (0.77 at time 1 and 0.55 at time 2) than for boys (0.14 and 0.0 at times 1 and 2, respectively). Heritability of Dental Fear Intensity, however, was similar for girls (0.30 and 0.40 at times 1 and 2, respectively) and boys (0.47, 0.44). Studies of the etiology of dental fear/anxiety should take genetic vulnerability into account and include molecular biology measures. Possible heritability differences between girls and boys need attention.

Abstract
This study evaluates the incidence of non-use and limited use of cochlear implants and attempts to identify predictors of such outcome. This involved a retrospective analysis of questionnaires, clinical and audiological data of 423 cochlear implant recipients from the Midland Adult Cochlear Implant Programme and Birmingham Paediatric Cochlear Implant Programme between 1990 and 2000. Of the 172 children in the paediatric programme 5 (2.9%) were non/limited users and of the 251 adults in the adult programme 7 (2.78%) were non/limited users. Thus in total 12 (2.82%) recipients were deemed to be either limited users (0.94%) or non-users (1.89%) of their implants. The mean duration of deafness prior to implantation was around 10 years in both the paediatric and adult groups. In the paediatric group, peer pressure played a prominent role in the non-use of implant. Depression, tinnitus, concomitant neurological problems and non-auditory stimulation seemed to be the predominant reasons in the older age group. The reasons for limited use were cognitive slowing and problems with background noise.
