The Erice 58 Charter on 'The health of migrants. An equity challenge for the public health system'.

Abstract: The Erice 58 Charter titled "The Health of Migrants: a Challenge of Equity for the Public Health System", was unanimously approved at the conclusion of the 58th Residential Course of the School of Epidemiology and Preventive Medicine 'Giuseppe D'Alessandro' entitled "The Health of Migrants: a Challenge of Equity for the Public Health System. Epidemiological, clinical-relational, regulatory, organisational, training and public communication aspects at international, national and local level', which took place from 28 March to 2 April 2022 in Erice (Sicily, Italy), at the 'Ettore Majorana' Foundation and Centre for Scientific Culture. The Course was promoted by the Italian Society of Migration Medicine (S.I.M.M.) and the Italian Society of Hygiene, Preventive Medicine and Public Health (SItI), with the collaboration and patronage of the Istituto Superiore di Sanità (ISS). 72 learners participated (mainly resident doctors in 'Hygiene and Preventive Medicine' but also other health service professionals), whose average age was 37 years; on the basis of territorial origin, 13 of the 20 Italian regions were represented. During the intense learning experience, which consisted of 18 frontal lessons (with 20 lecturers from the bio-medical, socio-anthropological and journalistic fields) and 7 working group sessions (supported by 4 classroom tutors in addition to the lecturers) in 'blended learning' mode, the various dimensions and critical issues related to the possibility of guaranteeing truly inclusive health policies for foreigners/migrants, throughout the country, were identified and discussed from an 'Health Equity' perspective. This enabled a small editorial group to draw up the basic document that, in the last session of the Course, was discussed and modified by all participants into the version of the 'Erice 58 Charter' presented here.

Vitamin D replacement ameliorates serum lipoprotein functions, adipokine profile and subclinical atherosclerosis in pre-menopausal women.

BACKGROUND AND AIMS: Low vitamin D (vitD) has been linked to increased cardiovascular (CV) risk, but the effects of vitD supplementation are not clarified. We evaluated the impact of vitD normalization on HDL cholesterol efflux capacity (CEC), which inversely correlates with CV risk, the proatherogenic serum cholesterol loading capacity (CLC), adipokine profile and subclinical atherosclerosis. METHODS AND RESULTS: Healthy premenopausal women with vitD deficiency (n = 31) underwent supplementation. Subclinical atherosclerosis was evaluated by flow-mediated dilation (FMD), pulse wave velocity (PWV) and augmentation index (AIx), measured with standard techniques. HDL CEC and serum CLC were measured by a radioisotopic and fluorimetric assay, respectively. Malondialdehyde (MDA) in HDL was quantified by the TBARS assay. Pre-ß HDL was assessed by 2D-electrophoresis. Serum adipokines were measured by ELISA. VitD replacement restored normal levels of serum 25-hydroxyvitamin D (25OHD) and significantly improved FMD (+4%; p < 0.001), PWV (-4.1%: p < 0.001) and AIx (-16.1%; p < 0.001). Total CEC was significantly improved (+19.5%; p = 0.003), with a specific increase in the ABCA1-mediated CEC (+70.8%; p < 0.001). HDL-MDA slightly but significantly decreased (-9.6%; p = 0.027), while no difference was detected in pre-ß HDL. No change was observed in aqueous diffusion nor in the ABCG1-mediated CEC. Serum CLC was significantly reduced (-13.3%; p = 0.026). Levels of adiponectin were increased (+50.6%; p < 0.0001) and resistin levels were decreased (-24.3%; p < 0.0001). After vitD replacement, an inverse relationship was found linking the ABCA1-mediated CEC with pre-ß HDL (r2 = 0.346; p < 0.001) and resistin (r2 = 0.220; p = 0.009). CONCLUSION: Our data support vitD supplementation for CV risk prevention.

Gene flow and population structure of a common agricultural wild species (Microtus agrestis) under different land management regimes.

The impact of landscape structure and land management on dispersal of populations of wild species inhabiting the agricultural landscape was investigated focusing on the field vole (Microtus agrestis) in three different areas in Denmark using molecular genetic markers. The main hypotheses were the following: (i) organic farms act as genetic sources and diversity reservoirs for species living in agricultural areas and (ii) gene flow and genetic structure in the agricultural landscape are influenced by the degree of landscape complexity and connectivity. A total of 443 individual voles were sampled within 2 consecutive years from two agricultural areas and one relatively undisturbed grassland area. As genetic markers, 15 polymorphic microsatellite loci (nuclear markers) and the central part of the cytochrome-b (mitochondrial sequence) were analysed for all samples. The results indicate that management (that is, organic or conventional management) was important for genetic population structure across the landscape, but that landscape structure was the main factor shaping gene flow and genetic diversity. More importantly, the presence of organically managed areas did not act as a genetic reservoir for conventional areas, instead the most important predictor of effective population size was the amount of unmanaged available habitat (core area). The relatively undisturbed natural area showed a lower level of genetic structuring and genetic diversity compared with the two agricultural areas. These findings altogether suggest that political decisions for supporting wildlife friendly land management should take into account both management and landscape structure factors.

Effects of antihypertensive treatments on incidence of diabetes: a case-control study.

AIMS: Aim of this case-control study is the assessment of the relationship between antihypertensive treatment and incidence of diabetes in an unselected cohort of subjects participating in a screening program for diabetes. METHODS: A case-control study nested within a cohort of nondiabetic subjects with a mean follow-up of 27.7 ± 11.3 months was performed, comparing 40 cases of incident diabetes and 160 controls matched for age, sex, body mass index, fasting plasma glucose, 2-h post-load glycemia, smoking and alcohol abuse. RESULTS: When considering antihypertensive treatment at enrolment, a lower proportion of cases was exposed to ACE-inhibitors/angiotensin receptor blockers (ACE-i/ARB) in comparison with controls. A non-significant trend toward a higher exposure to diuretics, which were mainly represented by thiazide diuretics, was observed in cases. In a multivariate analysis, including both ACE-i/ARB and diuretics, a protective effect of ACEi/ARB, and an increased risk with diuretics were observed. Similar results were obtained in alternative models, after adjusting for systolic and diastolic blood pressure at enrolment, diagnosis of hypertension, concurrent treatment with ß-blockers or calcium-channel blockers, and number of antihypertensive medications. CONCLUSIONS: Diuretics seem to be associated with a higher incidence of diabetes, whereas treatment with ACEi/ARB could have a protective effect.

[Results and development in cancer screening programs]. / Risultati e sviluppi dei programmi di screening oncologici.

In order to contribute to the definition of good model for cancer screening programs, the paper reports an overview of Veneto Local Health Units' results according to required "gold standard" defined by the authors. The analysis was based on a standard attesting that the program is running stabely and a standard for the organisation requiring that general management is performed by a unique central unit, supplied with a unique software and a working group equipped with specific know-how. Ten of the 21 Locale Health Unit of Veneto Region chose to assign to Prevention Department (Public Health Department) all the three screening programs included in the National Prevention Plan. Among these we found the two achieving the defined gold standard (Thiene and Pieve di Soligo). Management model implemented in these units showed a framework for excellence.

Ruptured chordae tendineae of the posterior leaflet of the tricuspid valve as a cause of tricuspid regurgitation following blunt chest trauma.

A 12-year-old boy suffered a blunt chest trauma. Some hours later, a pulsatile bilateral jugular venous distension, a holosystolic murmur heard at the low parasternal border and hepatomegaly were observed. On echocardiography, ruptured chordae tendineae of the posterior leaflet of the tricuspid valve, as well as tricuspid regurgitation were detected. He remained asymptomatic during hospital stay and was discharged home in good condition. Thus, isolated ruptured chordae tendineae of the posterior leaflet of the tricuspid valve is another cause of tricuspid regurgitation following blunt chest trauma.

Total gastrectomy in the treatment of adenocarcinoma of the cardia. Review of the results in 73 resected patients.

Between January 1, 1971, and December 31, 1978, 73 patients with adenocarcinoma of the cardia were treated by total gastrectomy with distal esophagectomy. The continuity of the alimentary tract was restored by esophagojejunostomy using a Roux-Y procedure in 32 patients and jejunal loop interposition in 41 patients. The early postoperative mortality rate was 18 percent. The overall 5 year survival rate was 26.7 percent, and the 5 year survival rate for stage I and II disease was 91.6 percent and 25 percent, respectively, whereas none of the stage III and IV patients survived more than 4 years. Fifty-eight percent of the patients without nodal involvement lived more than 5 years. The 5 year survival rate was only 9.3 percent in the presence of nodal metastases. Our 5 year survival rates suggest the value of elective total gastrectomy for stage I or II adenocarcinoma of the cardia. Jejunal loop interposition is a time-consuming but functionally superior procedure in comparison to other reconstructive procedures after total gastrectomy.

Two-dimensional echocardiography in post traumatic tricuspid incompetence.

Four patients with post traumatic tricuspid incompetence underwent complete two-dimensional echocardiographic study. Systolic intra-atrial protrusion of the anterior tricuspid leaflet beyond the valvular ring, with total loss of coaptation with the other leaflets, was documented in all patients. These abnormalities were not evident in all transducer locations suggesting the possibility of false negative echocardiograms. An echocardiogram showing a marked systolic excursion of a tricuspid leaflet into the right atrium beyond the level of the tricuspid ring together with the total loss of coaptation does not necessarily mean the rupture of the subvalvular apparatus.

Trypanosoma cruzi parasitemia observed in immunocompromised patients: the importance of the artificial xenodiagnosis.

Trypanosoma cruzi parasitemia observed in immunocompromised patients (transplant or positive HIV) occurred more frequently by the artificial xenodiagnosis method (10/38) compared with hemoculture (2/38), given the same quantity of blood. Other ways of diagnosis, like mice inoculation (5/38), QBC and buffy coat (2/38), were evaluated also. This result showed the importance of the artificial xenodiagnosis. The other techniques increased only one more patient positive.

[Cardial achalasia and emotional stress. Considerations on 47 clinical cases]. / Acalasia cardiale e stress emotivo. Considerazioni su 47 casi clinici.

Reference is made to personal experience of psycholability is most patients with cardiac achalasia in presenting the results of a preliminary study of the relation between psychic trauma and the onset of this affection, in which a retrospective investigation was made of 47 clinical records prepared for surgical purposes, and hence poorly oriented. It was found that 16 patients (34%) spontaneously reported that dysphagia was closely related to a psychic trauma in terms of time. While no aetiopathogenetic theories can be founded on this observation, it suggests that the question can be usefully examined further by means of more specific psychological investigations that are more appropriate for employment in subsequent cases, the aim being to determine whether the trauma in question triggers the disease, or is simply a sign revealing the presence of an already existing condition.

[Protocol of combined surgical and polychemico-immunoradiologic therapy of stage T2N2MO lung cancer]. / Protocollo di trattamento combinato, chirurgico e polichemio-immuno-radioterapico del carcinoma polmonare allo stadio T2N2M0.

Preliminary data on the use of a combined surgical-polychemical-immunoradiotherapy protocol in the treatment of 13 T2N2M0 lung cancer patients are reported. The results are compared with those obtained in a 13 patient control group, homogenous by histotype, stage and surgical treatment who were given no other therapy. At 24 months the average survival rate in the first group was 61.5% compared to 15.3% in the second. It was significant that survival at 24 months after pneumonectomy rose from 16.6% to 50% and even more significantly survival after lobectomy rose from 14.2% to 71.4%.

[An attempt to detect Trypanosoma cruzi in the peripheral blood of patients with Chagas' disease, in chronic phase, using quantitative buffy coat (QBC)]. / Tentativa de evidenciar o Trypanosoma cruzi no sangue periférico de pacientes com doença de Chagas, em fase crônica, por meio do Quantitative Buffy coat (QBC).

Taking for granted the sensitivity of the Quantitative Buffy Coat (QBC) system, as documented in a murine experimental model, we assayed to detect Trypanosoma cruzi in the peripheral blood of 100 patients with Chagas disease in its chronic phase. By means of the method, no positivity occurred, evently as a consequence of small parasitemias, undetectable by this technique as assessed by the cases in consideration.

[Extensive cardiac angiosarcoma in the course of immunosuppressive therapy after kidney transplant]. / Esteso angiosarcoma cardiaco in corso di terapia immunosoppressiva post-trapianto renale.

We present a case of a 49-year-old man who underwent a kidney transplant. Treatment with azathioprine and steroid was increased due to an initial rejection of the allograft. Six months later, the patient experienced palpitations and precordial pain: the electrocardiogram recorded atrial fibrillation and the echocardiogram showed moderate pericardial effusion and the presence of a right atrial mass with infiltration into the interatrial septum and right ventricle. Computed tomography imaging confirmed the tumoral mass and magnetic resonance imaging revealed the extensive involvement of the right atrium, right ventricle and superior vena cava, suggesting the presence of an angiosarcoma of the heart. Despite chemotherapy the patient died within 1 month. The diagnosis was confirmed by autopsy, histological section, and electron microscopy examination.
