Can ultraviolet radiation act as a survival enhancer for cutaneous melanoma?

Some studies have suggested that sun exposure plays a protective role in melanoma survival. This created a paradox as the known carcinogen can act as a cancer promoter and also as a survival enhancer. The aim of this study was to investigate the effect of sun exposure on melanoma mortality using both ambient sun exposure and individual data. A 10-year cohort study was carried out on primary cutaneous melanoma cases (n=972). Residential data were coupled with levels of ultraviolet radiation (UV) to provide a measure of individual exposure. Demographic, histological and clinical data were obtained for all participants. In a subsample, information on pigmentary characteristics, diet, medical history, phenotype and self-reported sun exposure was also collected. Survival analysis and Cox proportional hazards models were used to examine associations. No protective effect was found for UVB or individual sun exposure variables on melanoma mortality. However, an increased risk of mortality was found among patients with cutaneous melanoma located on the lower limbs and in the highest decile of UVB exposure (≥3.298 J/cm) after controlling for sex, age and Breslow thickness (relative risk: 4.78; 95% confidence interval: 1.30-17.5). The increased risk of mortality for the highest decile of UVB was also confirmed in the subsample after controlling for sex, age, education, use of sun lamps, pigmentary characteristics and diet. The results of the study suggested no protective effect of sun exposure for melanoma mortality and showed that high sun exposure increases the risk of melanoma mortality among patients with melanomas located on the lower limbs

Implementing a group singing intervention for postpartum depression within the Italian health service

Background: In the United Kingdom a singing intervention for Postpartum Depression (PPD) titled “Music and Motherhood” was found to be effective. The World Health Organization Regional Office for Europe coordinated a study to assess the feasibility of implementing and adapting the intervention in other countries. In Italy, recent studies have highlighted the need to promote the availability of effective interventions for PPD in primary care. Aim: To describe the implementation of “Music and Motherhood” within the Italian primary care services dedicated to pregnancy and postnatal care in three different geographical locations, thus providing an example of strategies for implementing an arts and health intervention in primary care that can improve health and well-being. Methods: A 10-week group singing intervention for mothers with PPD was conducted as part of a single arm feasibility study. Data were collected through one-to-one interviews, focus groups and questionnaires from the professionals involved in the implementation and selected participating mothers. A conceptual framework including acceptability, appropriateness, feasibility, fidelity, implementation process, costs and sustainability was adopted for analysis. Number of sessions attended by mothers and implementation outcome measures for acceptability, appropriateness and feasibility, each consisting of four items rated on a 5-point Likert scale were also gathered. Results: The intervention was found to be inclusive of women from different socio-cultural backgrounds and appropriate to the context. The group setting and the use of an arts-based intervention helped to de-medicalise the process of care maximising resources. Singing helped mothers to express their feelings and find strategies to improve interaction with their child. Attention to mothers’ needs and the co-presence of the professional singing leader and a health professional were among the key factors. The median number of sessions attended was nine out of 10. In terms of acceptability, almost 90% of the professionals were in complete agreement that they liked and approved the intervention. Conclusion: Our study adds to the evidence that an arts and health intervention proven effective in one culture and linguistic context can be adapted to another. Collaboration among health professionals and artists in the implementation process and adequate funding are instrumental in moving from project to programme level

Comparative immunogenicity and efficacy of equivalent outer membrane vesicle and glycoconjugate vaccines against nontyphoidal Salmonella.

Nontyphoidal Salmonellae cause a devastating burden of invasive disease in sub-Saharan Africa with high levels of antimicrobial resistance. Vaccination has potential for a major global health impact, but no licensed vaccine is available. The lack of commercial incentive makes simple, affordable technologies the preferred route for vaccine development. Here we compare equivalent Generalized Modules for Membrane Antigens (GMMA) outer membrane vesicles and O-antigen-CRM197 glycoconjugates to deliver lipopolysaccharide O-antigen in bivalent Salmonella Typhimurium and Enteritidis vaccines. Salmonella strains were chosen and tolR deleted to induce GMMA production. O-antigens were extracted from wild-type bacteria and conjugated to CRM197 Purified GMMA and glycoconjugates were characterized and tested in mice for immunogenicity and ability to reduce Salmonella infection. GMMA and glycoconjugate O-antigen had similar structural characteristics, O-acetylation, and glucosylation levels. Immunization with GMMA induced higher anti-O-antigen IgG than glycoconjugate administered without Alhydrogel adjuvant. With Alhydrogel, antibody levels were similar. GMMA induced a diverse antibody isotype profile with greater serum bactericidal activity than glycoconjugate, which induced almost exclusively IgG1. Immunization reduced bacterial colonization of mice subsequently infected with SalmonellaS Typhimurium numbers were lower in tissues of mice vaccinated with GMMA compared with glycoconjugate. S. Enteritidis burden in the tissues was similar in mice immunized with either vaccine. With favorable immunogenicity, low cost, and ability to induce functional antibodies and reduce bacterial burden, GMMA offer a promising strategy for the development of a nontyphoidal Salmonella vaccine compared with established glycoconjugates. GMMA technology is potentially attractive for development of vaccines against other bacteria of global health significance

Pain as Defining Feature of Health Status and Prominent Therapeutic Target in Patients with Hidradenitis Suppurativa

Background. Pain is one of the main aspects of hidradenitis suppurativa that strongly affects the quality of life of patients. We explored the relationship between pain and clinical severity as well as its role in defining the health status in patients with HS. Methods. Pain was defined by three measures: (a) question 1 (“my skin hurts”) of the Skindex-17; (b) Bodily Pain (BP) scale of the SF-36; and (c) Visual Analog Scale (VAS). Clinical severity of HS was assessed by the Hurley staging, the Sartorius HS Score, and the International HS Severity Score System. Results. The study population included 341 HS patients with complete data for the VAS pain, 316 for question 1 of the Skindex-17, and 294 for BP. Clinical severity was positively associated with pain. This result was observed for all three severity scores and all three pain evaluation methods. In addition, the number of fistulae, abscesses, and nodules were significantly associated with the three severity measures of pain, while the association with scars was not observed for question 1 of the Skindex-17 and BP. Conclusions. Pain may be a good proxy of clinical severity and efficacy of a treatment in HS and therefore a crucial hallmark of patients’ health status

Occupational exposure to arsenic, mercury and UV radiation and risk of melanoma: a case-control study from Italy

Melanoma is mainly caused by sunlight radiation, but other environmental risk factors are not well known. We investigated the association between cutaneous melanoma and occupational exposure to arsenic, mercury and UV radiation

Perinatal mental health care in the Italian Mental Health Departments: a national survey

Background Evidence on the negative outcomes of untreated mental disorders during pregnancy and in the first year after childbirth on women and children's health has stimulated interest in how to develop and sustain high-quality mental health care during the perinatal period. In Italy, there is a lack of knowledge about how mental health services support women with perinatal mental disorders (PMDs). This study aims to describe the adoption of good practices for the prevention and care of PMDs by the Italian Mental Health Departments (MHDs). Methods This is a nationwide cross-sectional survey conducted online using LimeSurvey. Starting from the Ministry of Health Registry 127 MHDs were invited to participate between February and March 2023. Characteristics of the participating MHDs were reported as descriptive statistics. Results One hundred and nineteen MHDs participated, with a response rate of 93.7%. Regarding the prevention of PMDs, 69 (58.0%) MHDs offer preconception counselling, whereas only 6 (5.0%) have information material for this purpose. Written integrated care pathways for PMDs are not available in 94 (79.7%) MHDs. A reference professional for psychopharmacological treatment during pregnancy or breastfeeding is available in 55 (46.2%) MHDs while a specific treatment plan for women with PMDs is adopted by 27 (22.7%) MHDs. Thirty-four (28.6%) MHDs have established an outpatient clinic for PMDs, whereas there are no inpatient psychiatric facilities designed for mothers and infants (Mother-baby Units). Conclusions There is a need to improve the care of women with PMDs in Italy. The provision of pre- conception counselling, integrated care pathways and specialist skills and facilities for PMDs should be prioritised

High expression of the mismatch repair protein MSH6 is associated with poor patient survival in melanoma

OBJECTIVES: The outcome of patients with primary melanoma (PM) cannot be completely explained based on currently adopted clinical-histopathologic criteria. In this study, we evaluated the potential prognostic value of mismatch repair protein expression in PMs. METHODS: We examined the immunohistochemical staining of mismatch repair proteins in 18 benign nevi and 101 stage I to III PMs and investigated their association with tumor clinicopathologic variables and melanoma mortality. RESULTS: Expression of MSH2, MLH1, and PMS2 was high in benign nevi and reduced in a subset of PMs. Conversely, MSH6 expression was absent or extremely low in benign nevi and increased in a subset of PMs. In the multivariate analysis, including sex, age, Breslow thickness, and ulceration, high MSH6 expression in PMs (ie, immunostaining in >20% of tumor cells) was significantly associated with an increased risk of melanoma mortality (relative risk, 3.76; 95% confidence interval, 1.12-12.70). CONCLUSIONS: MSH6 protein expression can be a valuable marker to improve prognosis assessment in PMs
