LTBI among migrants by Mediterranean Sea: assessing prevalence and its variations according with different thresholds and diagnostic tools. A 10-month on-field experience.

Background: In 2016, 362 753 migrants reached Europe by sea. Most of migrants come from high tuberculosis (TB) burden countries and travel in conditions that increase the risk for communicable diseases. The goal of WHO End TB Strategy is to end global epidemic by 2035. Management of latent TB infection (LTBI) in low TB incidence countries is thus essential. Nevertheless, a lack of uniformity in policies and procedures for LTBI screening in Europe is perceived. The aim of this study was to estimate the LTBI prevalence in migrants by Mediterranean Sea. Methods: A cross-sectional study was conducted, involving 1038 migrants. Since a gold standard method is not available, LTBI prevalence was assessed in four alternative scenarios with different thresholds and diagnostic tools: (i) TST ≥ 5 mm; (ii) TST ≥ 10 mm; (iii) TST ≥ 5 mm plus IGRA; and (iv) TST ≥ 10 mm plus IGRA. TST = tuberculin skin test; IGRA = interferon-gamma release assay. Results: The four scenarios returned the following prevalence: (i) TST ≥ 5 mm: 40%; (ii) TST ≥ 10 mm: 33%; (iii) TST ≥ 5 mm plus IGRA: 27%; and (iv) TST ≥ 10 mm plus IGRA: 25%. Moreover, a positive association was found between the proportion of IGRA positive patients and the size of TST induration site. No patient who reported TST ≥ 18 mm tested IGRA negative. Conclusions: Prevalence varied substantially in the investigated scenarios. Significant differences were noted according with the nationality of migrants, probably attributable to different Bacillus Calmette-Guérin vaccination coverage rates in the countries of origin or different exposition to non-tuberculous mycobacteria infection. Data about the nationality can suggest the need of a tailored approach according to migrants' area of origin.

[The role of the public health personnel in the Prevention Department (in the Hygiene Services and Public Health Care and Hygiene of Food and Nutrition): proposal for the future of public health care]. / Il ruolo del medico di sanità pubblica del Dipartimento di prevenzione (nei servizi di Igiene e Sanità Pubblica e Igiene degli Alimenti e Nutrizione): una proposta per il futuro della sanità pubblica.

A global and local discussion on Public Health relevance is taking place, including the future role and organization of its services. Noteworthy becomes the role played by Public Health Specialists. This work presents the results of a workshop, carried out following the Guilbert methodology, whose aim was to define Public Health Doctors functions and their related activities. The programme involved 30 professionals from Triveneto area (North Eastern Italy), working in Prevention Departments at National Health Service and Universities. The key-functions identified were: 1) Health status assessment and identification of community risk factors, 2) Health Promotion, 3) Prevention, 4) Protection, 5) Planning, 6) Communication, 7) Professional Training, 8) Alliances and resources for complex Public Health programs, 9) Crisis management in Public Health, 10) Research. For each function activities were identified, meaning concerning areas and contents that must be warranted by professionals. This experience allowed to share existing attitudes and experiences present in Triveneto area, and it can stand as a feasible instrument for different settings. Nevertheless, it appears mandatory explaining at each level in the society role and functions of Prevention Departments.

Prevalence of overweight and obesity among school-aged children in urban, rural and mountain areas of the Veneto Region, Italy.

OBJECTIVE: To define the prevalence of overweight and obesity among school-aged children resident in mountain areas, rural areas and urban areas. DESIGN, SETTING AND SUBJECTS: The sample (n = 12832; 50.7% boys) included 9- and 11-year-old children of the Veneto Region of north-east Italy. Overweight and obesity status were determined using the International Obesity Task Force cut-off points for body mass index. The prevalence of overweight and obese subjects was calculated with a confidence interval of 95%. The Mantel-Haenszel method was used to compare the combined prevalence of overweight and obesity among children resident in mountain areas, rural areas and urban areas. RESULTS: Among boys the prevalence of overweight was 21.06%, while obesity prevalence was 5.92%; among girls overweight prevalence was 21.30%, while obesity prevalence was 5.15%. The prevalence was higher among 11-year-old boys (odds ratio (OR) = 1.19; 95% confidence interval (CI): 1.06-1.33) and 9-year-old girls (OR = 1.13; 95% CI: 1.01-1.26). Children resident in rural areas presented a higher risk of overweight and obesity compared with children resident in mountain areas (Mantel-Haenszel OR = 1.27; 95% CI: 1.13-1.42; chi2 = 17.55; P < 0.0001) and in urban areas (Mantel-Haenszel OR = 1.18; 95% CI: 1.07-1.31; chi2 = 10.39; P < 0.001). CONCLUSIONS: A relevant prevalence of overweight and obesity was found; the excess weight concerns one child in four. There are differences linked to different geographical areas that must be further investigated.
