Social media have become a common way for people to express their personal viewpoints, including sentiments about health topics. We present the results of an opinion mining analysis on vaccination performed on Twitter from September 2016 to August 2017 in Italy. Vaccine-related tweets were automatically classified as against, in favor or neutral in respect of the vaccination topic by means of supervised machine-learning techniques. During this period, we found an increasing trend in the number of tweets on this topic. According to the overall analysis by category, 60% of tweets were classified as neutral, 23% against vaccination, and 17% in favor of vaccination. Vaccine-related events appeared able to influence the number and the opinion polarity of tweets. In particular, the approval of the decree introducing mandatory immunization for selected childhood diseases produced a prominent effect in the social discussion in terms of number of tweets. Opinion mining analysis based on Twitter showed to be a potentially useful and timely sentinel system to assess the orientation of public opinion toward vaccination and, in future, it may effectively contribute to the development of appropriate communication and information strategies.

Hydroxyurea is an antitumoral drug mainly used in the treatment of Philadelphia chromosome-negative myeloproliferative syndromes and sickle-cell disease. Ulcers represent a rare but severe long-term adverse effect of hydroxyurea therapy. Hydroxyurea-induced ulcers are often multiple and bilateral, typically developing in the perimalleolar region, although any cutaneous district is potentially affected. They generally look small, well-defined, shallow with an adherent, yellow, fibrinous necrotic base. A constant finding is also an extremely intense, treatment-resistant pain accompanying these ulcerations. Withdrawal of the drug generally leads to spontaneous healing of these lesions. Care providers tend to show insufficient awareness of this highly debilitating cutaneous side effect, and late or missed diagnoses are frequent. Instead, regular dermatologic screening should be performed on hydroxyurea-treated patients. This article will present a comprehensive review of indexed case reports and clinical studies, followed by a discussion about treatment options aiming at increasing knowledge about this specific topic.

We describe a nosocomial outbreak of measles that occurred in an Italian hospital during the first months of 2017, involving 35 persons and including healthcare workers, support personnel working in the hospital, visitors and community contacts. Late diagnosis of the first case, support personnel not being promptly recognised as hospital workers and diffusion of the infection in the emergency department had a major role in sustaining this outbreak.

This paper outlines the characteristics of scientific leadership and the role of Scientific Associations with their specific activities. The recent activities of the Lombard Academy of Public Health are subsequently described, including the creation, in 2019, of the Academy of young leaders in public health. Comparing to other sectors, scientific leadership dynamics take into consideration different aspects. Besides awards (Nobel Prize or several other) and prestigious affiliations, eventual indicators might be academic roles, fundraising abilities, relevant positions among scientific associations, editors of prestigious journals or editorial series and, more recently, high bibliometric indicators. The peculiar topics of public health encompass interactions with institutions, authorities, politicians, involved in different levels in health policies. Recently, in Italy, the Ministry of Health has identified parameters to be accreditated as a scientific and technical association. The role of SItI (Italian Society of Hygiene), EUPHA, ASPHER, and WFPHA appears relevant in PH, in national and international contexts, with Italian praiseworthy members constantly achieving leading roles. Considering that few training opportunities aimed to improve research and leadership skills are available, Accademia Lombarda di Sanità Pubblica (ALSP) designed the AYLPH (Academy of Young Leaders in Public Health) program. AYLPH program is a 1-year training to shape leadership skills among young professionals. A set of didactic, theoretical and practical methods was offered and evaluated.

Congenital heart block (CHB) is a transplacentally acquired autoimmune disease associated with anti-Ro/SSA and anti-La/SSB maternal autoantibodies and is characterized primarily by atrioventricular (AV) block of the fetal heart. This study aims to investigate whether the T-type calcium channel subunit α_1G may be a fetal target of maternal sera autoantibodies in CHB. We demonstrate differential mRNA expression of the T-type calcium channel CACNA1G (α_1G gene) in the AV junction of human fetal hearts compared to the apex (18–22.6 weeks gestation). Using human fetal hearts (20–22 wks gestation), our immunoprecipitation (IP), Western blot analysis and immunofluorescence (IF) staining results, taken together, demonstrate accessibility of the α_1G epitope on the surfaces of cardiomyocytes as well as reactivity of maternal serum from CHB affected pregnancies to the α_1G protein. By ELISA we demonstrated maternal sera reactivity to α_1G was significantly higher in CHB maternal sera compared to controls, and reactivity was epitope mapped to a peptide designated as p305 (corresponding to aa305–319 of the extracellular loop linking transmembrane segments S5–S6 in α_1G repeat I). Maternal sera from CHB affected pregnancies also reacted more weakly to the homologous region (7/15 amino acids conserved) of the α_1H channel. Electrophysiology experiments with single-cell patch-clamp also demonstrated effects of CHB maternal sera on T-type current in mouse sinoatrial node (SAN) cells. Taken together, these results indicate that CHB maternal sera antibodies readily target an extracellular epitope of α_1G T-type calcium channels in human fetal cardiomyocytes. CHB maternal sera also show reactivity for α_1H suggesting that autoantibodies can target multiple fetal targets.

Higher education institutions (HEIs) worldwide have been deeply affected by the Coronavirus Disease 2019 (COVID-19) pandemic and subsequent lockdown measures. HEIs are environments at high risk of COVID-19 diffusion, due to the high number of people sharing the same environment, and complex to protect, because of the multiple functions present (e.g. teaching rooms, research facilities, dormitories). Protection of HEIs is therefore a serious, but apparently neglect, public health issue. Italy was the first country to be heavily hit in Europe by COVID-19. Italian HEIs had to quickly respond to the emergency with multifaceted interventions to protect all the people on campus while guaranteeing the continuity of research and teaching activities. The purpose of this viewpoint is to propose and discuss a list of priority actions for the protection of HEIs, based on international guidelines and the experience of a small size Italian Public University and Research campus.
