Study of occupational and environmental exposure to asbestos through linkage methods and spatial analysis

INTRODUCTION The identification and monitoring of cancers caused by occupational or environmental exposure to asbestos is an important aspect of public health The first aim of the study was to identify patients with a cancer different from malignant mesothelioma (MM), who worked in firm with at least possible occupational asbestos exposure [BRIC]. The second aim was to assess the spatial variation of MM risk in the area of Casale Monferrato and to detect clustering associated to the secondary sources of asbestos [LATENT]. METHODS For the first project [BRIC], we considered the registries of MM from seven Italian Regions, while the other cancer cases (OCM) were available only for two. As ReNaM and OCM could not be merged directly due the absence of a linkage key, different linkage methods were implemented. For the second project [LATENT], we used data from a population-based case–control study conducted in Casale Monferrato between 2001 and 2006. Demographic and occupational data along with residential information were recorded. The spatial variation in disease risk was mapped and adjusted logistic models were applied. RESULTS In BRIC, we included 4134 cases of MM recorded in ReNaM, corresponding to 12801 occupational records. The linkage procedure allowed to identify 2606 firms with asbestos exposure. Of 35010 cases included in the OCM system, 6546 (18.7%) worked in these firms. One hundred ninety-six cases and 322 controls were included in the analyses of LATENT project. The plot showed a well-defined peak of MM incidence near the asbestos cement factory when large bandwidths were used. However, changing parameters, several peaks of increased risk were reported. A constant trend of decreasing Odds Ratio with increasing distance was observed, with estimates of 10.9 and 10.48 for 0-5 km and 5-10 km, respectively (reference >15 km). CONCLUSION The project has allowed to deepen the study of the effect of two types of asbestos exposure: occupational and environmental

Effectiveness-implementation hybrid type 2 study evaluating an intervention to support ‘information work’ in dementia care: an implementation study protocol

Introduction Patients with long-term conditions consistently report a lack of information around services and support available to them. This unmet need for information is significant among people with dementia and family carers. A quality improvement intervention is being carried out to tackle this issue as part of a co-creation initiative in the North East of England (UK). The intervention consists of the dissemination (via the local Community Mental Health Services for Older People) of a leaflet about services available to people with dementia and their family carers in the study site. This protocol is reported in accordance with the Standards for Reporting Implementation Studies. Methods and analysis This effectiveness–implementation hybrid type 2 study aims at understanding (1) the unfolding and outcomes of the implementation strategy, (2) the outcomes of the intervention (for people with dementia and family carers, staff implementing the intervention and local service providers) and (3) the contribution of co-creation to the design and implementation of the intervention and its outcomes. The prospective theory of change of the intervention articulated by local stakeholders is used as a reference framework against which to assess the implementation and outcomes of the intervention. Evaluation data will be collected through in-depth interviews with people with dementia and family carers receiving the intervention, staff implementing the intervention and managers from local service providers. Referral data from local service providers will be collected to triangulate the interview data. A focus group with key stakeholders will support the sense-making of findings. The realist configuration of mechanism–context–outcome, operationalised using an information behaviour model, will inform data analysis and interpretation. Ethics and dissemination Ethical and research governance approvals have been obtained from the West Midlands—South Birmingham Research Ethics Committee. The results of the study will be submitted for publication in peer-reviewed journals and disseminated through conferences

Efectos sobre el desempeño visual de dos filtros Longpass

Purpose: This study compared visual performance and optical properties of three filters. Method: Two groups of twenty adults were recruited: wearers of progressive addition lenses (PAL, 46–73 years) and wearers of single vision lenses (SVL, 26–55 years). Three spectacle filters (Hoya, Japan) were compared: clear control, Standard Drive (STD), and Professional Drive (PRO) lenses. Optical transmittance was measured by a Jasco V-650 spectrophotometer. Best corrected visual acuity (BCVA) was measured in photopic (BCVAphotopic) and mesopic (BCVAmesopic) conditions and under glare (BCVAglare). Photopic contrast sensitivity (CS) was also measured. Results: The three longpass filters show cutoff at 426 ± 2 nm (STD/PRO) and 405 ± 2 nm (clear lens). BCVAglare improved with Drive filters compared to the clear one (p < 0.05) from 0.03 to -0.02 (STD) and to -0.01 (PRO) for PAL and from -0.08 to -0.12 (STD and PRO) for SVL. For PAL, BCVAmesopic improved from 0.15 to 0.12 (STD, p < 0.05) and 0.13 (PRO), while no substantial difference was observed for SVL. CS showed some improvements with Drive lenses at some angular frequencies between 6 and 18 cycles/deg, mainly for the PAL group. No BCVAphotopic differences were found. After testing all filters, each for two weeks, 79% (PAL) and 60% (SVL) of participants preferred Drive lenses. Conclusions: Drive lenses are found to maintain or improve some visual functions compared to the clear lens. The improvement of mesopic visual acuity, visual acuity under glare, and contrast sensitivity is mainly attributed to the reduction of intraocular light scattering as a consequence of the total light attenuation in the spectral range below the cutoff

Spatio-temporal patterns of genetic diversity in the Mediterranean striped dolphin (Stenella coeruleoalba)

Comparing the genetic composition of wild animals between geographic regions with distinct environments is common in evolutionary studies. However, genetic composition can also change through time in response to environmental changes but studies examining this are carried out less often. In this study, we characterise striped dolphin genetic composition in the Mediterranean Sea across both geography and time. We provide genotype data for 15 microsatellite loci and 919 bp of mtDNA control region, collected over 21 years across all main Mediterranean Sea basins. We investigated spatial genetic structure using both classical and Bayesian population structure methods, and compared it with temporal patterns of genetic change using time series statistics. We integrated the temporal datasets with known environmental pressures and data on social structure, to infer potential drivers of observed changes. Geographic analyses suggest weak differentiation for striped dolphin in the Mediterranean Sea, with evidence for a recent expansion. Temporal analyses show significant cyclical fluctuations in genetic composition over 21 years, which correspond well with recurrent morbillivirus epizootics. Similarly, social group composition shows changes in the relative number of juveniles and adults per group, and an overall increase in the number of adults per group relative to juveniles over the time period. We suggest that the observed changes in genetic and group composition could relate to specific dynamics of morbillivirus resistance. Overall, our study highlights the importance of tracking long term genetic variation, and the potential for this species as a model in studying genetic adaptation to environmental stress

Facial dermatoses and use of protective mask during Covid-19 pandemic: A clinical and psychological evaluation in patients affected by moderate-severe atopic dermatitis under treatment with dupilumab

During the SARS-COV-2 pandemic, using face masks became mandatory in many countries. Although evidence suggests that masks can exacerbate several inflammatory skin diseases, few studies focus on their real impact on eczema localized to the face in atopic dermatitis (AD) patients. The aim of this study is to evaluate facial eczema prevalence during pandemic and its psychological impact in AD patients pre-assessed for systemic treatment and/or in therapy with dupilumab. This study includes 71 patients affected by moderate-severe AD, treated with dupilumab at SCDU of Dermatology in Novara, Italy. We calculated the number of subjects with facial involvement in pre- and post-pandemic periods and the related localization trend. We evaluated, in the two groups, clinical and psychological indicators recorded at each visit and the score modifications during the observational period. No statistically significant differences were observed in facial eczema prevalence, between pre- and post-pandemic periods (p&nbsp;=&nbsp;0.7618) and in facial eczema remission among the two groups (p&nbsp;=&nbsp;0.1903). In post-pandemic period, psychological scores were significantly lower (DLQI and HADS respectively with p &lt; 0.0001 and p&nbsp;=&nbsp;0.0025) and the reduction in EASI score during observational period was significantly greater (p&nbsp;=&nbsp;0.0001). Our analysis revealed a potential protective effect of masks on face eczema, suggesting that they could enhance dupilumab efficacy. Face masks, covering sensitive areas, can positively contribute to mental distress in patients with facial eczema, and being associated with a lower allergic diseases incidence may sustain dupilumab in reducing AD severity

TTG1 proteins regulate circadian activity as well as epidermal cell fate and pigmentation.

The Arabidopsis genome contains three genes encoding proteins of the TRANSPARENT TESTA GLABRA 1 (TTG1) WD-repeat (WDR) subfamily. TTG1 is a known regulator of epidermal cell differentiation and pigment production, while LIGHT-REGULATED WD1 and LIGHT-REGULATED WD2 are known regulators of the circadian clock. Here, we discovered a new central role for TTG1 WDR proteins as regulators of the circadian system, as evidenced by the lack of detectable circadian rhythms in a triple lwd1 lwd2 ttg1 mutant. This shows that there has been subfunctionalization via protein changes within the angiosperms, with some TTG1 WDR proteins developing a stronger role in circadian clock regulation while losing the protein characteristics essential for pigment production and epidermal cell specification, and others weakening their ability to drive circadian clock regulation. Our work shows that even where proteins are very conserved, small changes can drive big functional differences.CAA acknowledges support from the Cambridge University Botanic Garden Research Fund.

AKASI and Near-Infrared Spectroscopy in the combined effectiveness evaluation of an actinic keratoses preventive product in immunocompetent and immunocompromised patients

Introduction: The high incidence of actinic keratoses among both the elderly population and immunocompromised subjects and the considerable risk of progression from in situ to invasive neoplasms makes it essential to identify new prevention, treatment, and monitoring strategies.Objective: The aim of this study was to evaluate the efficacy on AKs of a topical product ((R) Rilastil AK Repair 100 +) containing high-protection sunscreens, a DNA Repair Complex with antioxidant and repairing action against UV-induced DNA damage, and nicotinamide, a water-soluble derivative of vitamin B3 that demonstrated several photoprotective effects both in vitro and in vivo.Methods: The study enrolled 74 Caucasian patients, which included 42 immunocompetent and 32 immunosuppressed subjects. The efficacy of the treatment has been evaluated through the clinical index AKASI score and the non-invasive Near-Infrared Spectroscopy method.Results: The AKASI score proved to be a valid tool to verify the efficacy of the product under study, highlighting an average percentage reduction at the end of treatment of 31.37% in immunocompetent patients and 22.76% in organ transplant recipients, in comparison to the initial values, with a statistically significant reduction also in the single time intervals (T0 vs. T1 and T1 vs. T2) in both groups. On the contrary, the Near-Infrared Spectroscopy (a non-invasive technique that evaluates hemoglobin relative concentration variations) did not find significant differences for O(2)Hb and HHb signals before and after the treatment, probably because the active ingredients of the product under study can repair the photo-induced cell damage, but do not significantly modify the vascularization of the treated areas.Conclusion: The results deriving from this study demonstrate the efficacy of the product under study, confirming the usefulness of the AKASI score in monitoring treated patients. Near-Infrared Spectroscopy could represent an interesting strategy for AK patients monitoring, even if further large-scale studies will be needed

The role of music in promoting health and wellbeing: a systematic review and meta-analysis

Background: The higher disease burden and related costs due to an increasing aging population have placed tremendous pressure on the healthcare systems worldwide. Given that music, both listened and actively performed, promotes and maintains good health and wellbeing among the population, we sought to perform a systematic review that would assess its biopsychosocial effects on a population over 40 years of age. Methods: A comprehensive search of peer-reviewed articles up to April 2021 was conducted on six electronic databases (i.e. Cochrane, MEDLINE, PubMed, PsycINFO, Web of Science and Scopus). Our study population only included healthy adults of 40 years and older. A total of 11 randomized controlled trials (RCTs) matched the inclusion criteria and were therefore analyzed. Results: Despite the heterogeneity of the methodologies used in the selected studies, our findings suggest that active musical participation can lead to beneficial effects on both cognitive and psychosocial functioning, whereas the positive impact of listening to music seems to be predominantly restricted to the cognitive domain. Conclusions: Although our results are consistent with both active and passive music activities favouring health and wellbeing in individuals 40 years old and over, future prospective RCTs, employing more uniformed and sensitive measurements, should allow us to better gauge the role of music participation in healthy aging and longevity, especially in countries with a high population density of elderly people
