Investigating strontium isotope linkage between biominerals (uroliths), drinking water and environmental matrices.

This study presents the mineralogy and strontium isotope ratio (87Sr/86Sr) of 21 pathological biominerals (bladder and kidney stones) collected from patients admitted between 2018 and 2020 at the Department of Urology of the San Pio Hospital (Benevento, southern Italy). Urinary stones belong to the calcium oxalate, purine or calcium phosphate mineralogy types. Their corresponding 87Sr/86Sr range from 0.707607 for an uricite sample to 0.709970 for a weddellite one, and seem to be partly discriminated based on the mineralogy. The comparison with the isotope characteristics of 38 representative Italian bottled and tap drinking waters show a general overlap in 87Sr/86Sr with the biominerals. However, on a smaller geographic area (Campania Region), we observe small 87Sr/86Sr differences between the biominerals and local waters. This may be explained by external Sr inputs for example from agriculture practices, inhaled aerosols (i.e., particulate matter), animal manure and sewage, non-regional foods. Nevertheless, biominerals of patients that stated to drink and eat local water/wines and foods every day exhibited a narrower 87Sr/86Sr range roughly matching the typical isotope ratios of local geological materials and waters, as well as those of archaeological biominerals from the same area. Finally, we conclude that the strontium isotope signature of urinary stones may reflect that of the environmental matrices surrounding patients, but future investigations are recommended to ultimately establish the potential for pathological biominerals as reliable biomonitoring proxies, taking into the account the contribution of the external sources of Sr.

May a comprehensive mineralogical study of a jackstone calculus and some other human bladder stones unveil health and environmental implications?

This paper represents the first result of an active collaboration between the University of Sannio and the San Pio Hospital (Benevento, Italy), started in the 2018, that aims to a detailed mineralogical investigation of urinary stones of patients from Campania region. Herein, selected human bladder stones have been deeply characterized for clinical purposes and environmental biomonitoring, focusing on the importance to evaluate the concentration and distribution of undesired trace elements by means of microscopic techniques in the place of conventional wet chemical analyses. A rare bladder stone with a sea-urchin appearance, known as jackstone calculus, were also investigated (along with bladder stones made of uric acid and brushite) by means a comprehensive analytical approach, including Synchrotron X-ray Diffraction and Simultaneous Thermal Analyses. Main clinical assumptions were inferred according to the morpho-constitutional classification of bladder stones and information about patient's medical history and lifestyle. In most of the analyzed uroliths, undesired trace elements such as copper, cadmium, lead, chromium, mercury and arsenic have been detected and generally attributable to environmental pollution or contaminated food. Simultaneous occurrence of selenium and mercury should denote a methylmercury detoxification process, probably leading to the formation of a very rare HgSe compound known as tiemannite.

Monitoring the process of measles elimination by serosurveillance data: The Apulian 2012 study.

In 2003 Italy adopted the National Plan for Measles and Congenital Rubella Elimination, but some outbreaks of measles are still occurring, as the target coverage rate (≥ 95%) for new-borns has currently not been achieved. In order to support the monitoring of the measles elimination programme, the authors carried out a survey about the seroprevalence of measles among Apulia young adults. The study was carried out from May 2011 to June 2012 among blood donors of the Department of Transfusion Medicine of Policlinico General Hospital in Bari. Subjects were enrolled by a convenience sampling. For each enrolled patient we collected a 5 mL serum sample. Collected sera were tested by chemiluminescence (CLIA) for anti-Measles IgG. We enrolled 1764 subjects; 1362 (77.2%) were male with a mean age of 38.4 ± 11.7 years. Anti-Measles IgG titre was >16.5UA/mL in 95.1% (95% CI=94.1-96.1) of enrolled subjects with a Geometric Mean Titre (GMT) of 2.3 ± 0.4, which did not differ dividing the enrolled subjects into age groups. As our data showed, the universal routine vaccination changed the epidemiological pattern among adults, in particular young adults (18-24 years), who showed lowest seropositivity rates; in these groups of population there is a risk of the onset of outbreaks due to the presence of susceptible population. This is a paradox linked to the vaccination strategy: when coverage rates keep sub-optimal, measles is more likely to affect young adults and a higher percentage of complications is expected. According to our data, health authorities have to plan a mop-up strategy to actively offer measles vaccination to susceptible young adults.

A seroprevalence survey on varicella among adults in the vaccination era in Apulia (Italy).

In 2006, the Apulia Region (Italy) introduced universal routine vaccination (URV) against varicella disease. The coverage for one dose of varicella vaccine at 24 month of age reached 91.1% in 2010 birth-cohort. Vaccination coverage for the second dose at 5-6 years was 64.8% for the cohort 2005, and 28.8% for adolescents born in 1997. The aim of the present study is to evaluate the pattern of immunity/susceptibility to varicella in Apulian adults by a seroprevalence survey carried out 6 years after the introduction of URV. The study was carried out from May 2011 to June 2012 among blood donors of the Department of Transfusion Medicine of Policlinico General Hospital in Bari. Subjects were enrolled by a convenience sample. For each enrolled patient we collected a sample of serum of 5 ml. Anti-VZV IgG in collected sera were analyzed by chemiluminescence (CLIA). We enrolled 1769 subject; 1365 (77.2%) were male with a mean age of 38.4 ± 11.7 years. 93% (95% CI=91.7-94.1) of enrolled subject presented a titre of anti-VZV IgG >164 mIU/mL. GMT of anti-VZV IgG titre was 1063.4 mIU/ml and no difference was observed between different age group. According to our data, URV did not seem to have any impact on susceptibility among adults and in particular we did not note any cluster of susceptible subjects among young adults. Also in the vaccination era, we did not note that the average age of infection shifts among adults and then we could exclude an increase of case of complicated varicella related to the URV.

Sporadic isolation of sabin-like polioviruses and high-level detection of non-polio enteroviruses during sewage surveillance in seven Italian cities, after several years of inactivated poliovirus vaccination.

Sewage surveillance in seven Italian cities between 2005 and 2008, after the introduction of inactivated poliovirus vaccination (IPV) in 2002, showed rare polioviruses, none that were wild-type or circulating vaccine-derived poliovirus (cVDPV), and many other enteroviruses among 1,392 samples analyzed. Two of five polioviruses (PV) detected were Sabin-like PV2 and three PV3, based on enzyme-linked immunosorbent assay (ELISA) and PCR results. Neurovirulence-related mutations were found in the 5'noncoding region (5'NCR) of all strains and, for a PV2, also in VP1 region 143 (Ile>Thr). Intertypic recombination in the 3D region was detected in a second PV2 (Sabin 2/Sabin 1) and a PV3 (Sabin 3/Sabin 2). The low mutation rate in VP1 for all PVs suggests limited interhuman virus passages, consistent with efficient polio immunization in Italy. Nonetheless, these findings highlight the risk of wild or Sabin poliovirus reintroduction from abroad. Non-polio enteroviruses (NPEVs) were detected, 448 of which were coxsackievirus B (CVB) and 294 of which were echoviruses (Echo). Fifty-six NPEVs failing serological typing were characterized by sequencing the VP1 region (nucleotides [nt] 2628 to 2976). A total of 448 CVB and 294 Echo strains were identified; among those strains, CVB2, CVB5, and Echo 11 predominated. Environmental CVB5 and CVB2 strains from this study showed high sequence identity with GenBank global strains. The high similarity between environmental NPEVs and clinical strains from the same areas of Italy and the same periods indicates that environmental strains reflect the viruses circulating in the population and highlights the potential risk of inefficient wastewater treatments. This study confirmed that sewage surveillance can be more sensitive than acute flaccid paralysis (AFP) surveillance in monitoring silent poliovirus circulation in the population as well as the suitability of molecular approaches to enterovirus typing.

Outbreak of Salmonella infantis gastroenteritis among people who had eaten at a hash house in southern Italy.

OBJECTIVES: To describe an outbreak of acute gastroenteritis in people who had eaten at a hash house in southern Italy. STUDY DESIGN: Case-control study. METHODS: A clinical case of gastroenteritis was defined as a person who had eaten at the hash house from 29 August to 4 September 2011 and who experienced defined gastrointestinal symptoms within 72 hours, or a person with a laboratory-confirmed salmonella infection without symptoms. A convenience sample was enrolled as the control group. Environmental and human samples were collected, and Salmonella infantis was identified by polymerase chain reaction. Univariate analysis was performed for each food type, and multivariate analysis was performed for each food type and demographic variable (gender, age). RESULTS: Twenty-three cases of gastroenteritis were notified between 1 and 4 September 2011, two of which were admitted to the local hospital. Multivariate analysis showed that porchetta [odds ratio (OR) 22.0, 95% confidence interval (CI) 3.2-152.6, z = 3.13, P = 0.002] and roasted meat (OR 14.4, 95% CI 1.7-122.0, z = 2.45, P = 0.014) were associated with gastrointestinal symptoms. Environmental and human isolates exhibited the same sequence type (ST 32). CONCLUSIONS: This experience highlighted that, in the control of a foodborne outbreak, integrated epidemiological and laboratory surveillance enables rapid identification of the source of infection, thus reducing the risk of an epidemic.

Addressing the anti-vaccination movement and the role of HCWs.

Over the last two decades, growing numbers of parents in the industrialized world are choosing not to have their children vaccinated. Trying to explain why this is occurring, public health commentators refer to the activities of an anti-vaccination movement. The aim of this paper is to review the literature about the anti-vaccination movements and to highlight the knowledge and the skills needed for HCWs to fight against their ideas. The main theoretical structures of anti-vaccination ideology in the 19th and 20th centuries are: vaccines cause idiopathic illness; opponents against vaccines accused vaccine partisans to be afraid of the "search after truth," they fear unveiling errors; the vaccination law not only insults every subject of the realm, but also it insults every human being; vaccine immunity is temporary; an alternative healthy lifestyle, personal hygiene and diet stop diseases. Proponents against vaccination now have additional means to communicate their positions to the general public, the Internet in particular. Doctors and HCWs constantly have to face parents and patients who search information about vaccination. A lot of these people have previously found data about vaccinations from a lot of sources, such as papers, media or in websites and in these sources most contents come from anti-vaccine movements. For these reasons doctors and HCWs need to have updated knowledge about the vaccinations and to know the contents proposed by vaccine sceptics. Educating the general public cannot be fully effective unless there is a corresponding provision, enthusiasm and commitment by trained HCWs.

Surveillance of new HIV infections/diagnoses in Puglia region (south Italy), years 2007-2011.

BACKGROUND: The aim of the study is to describe temporal trend, distribution and characteristics of new HIV infections detected in Puglia Region in years 2007-2011. METHODS: Case surveillance data for all individuals newly diagnosed with HIV infection in these years were analysed. Risk factors associated with late presentation at diagnosis were analysed by multivariate logistic analysis. RESULTS: In the years 2007-2011 a total of 632 new diagnoses of HIV infection were notified. 573 (90,7%) of all cases were residents (83,8% Italians, 16,2% migrants). Among residents, 76,8% were males (median age 36 years), 23,2% females (median age 30 years). On the whole, 58,3% were late presenters (LP) and 40,8% were subjects with advanced HIV disease (AHD). At multivariate analysis, older age and being a migrant were risk factors significantly associated with late presentation at diagnosis. CONCLUSIONS: Clinical-epidemiological analysis of new HIV diagnosis/infections in Puglia shows a high proportion of LP and AHD. The results of the study strongly suggest the need to promote access to counselling and screening services of subjects at high risk of late presentation for a better targeting of information campaigns.

An audit about clinical governance skills in Italian medical managers.

BACKGROUND: The objective of this study is to describe the knowledge and skills of managers working in health organizations in the Region of Puglia (South of Italy) on the principles and tools of clinical governance. METHODS: A KAP (Knowledge, Attitudes and Practice) survey was conducted using a questionnaire. The target population of the survey was represented by Hospital Directors and Managers of local health care structures (Primary Care Districts, Public Health Departments, and Mental Health Departments). RESULTS: 92 managers participated at the study (response rate was 90.2%). 98.9% of respondents reported being aware of the concept of clinical governance and believe that clinical governance is an appropriate strategy for the continuous improvement in quality of services. 96.7% of respondents had heard of Evidence Based Practice and 80.6% reported using the method of EBP in nursing practice. The availability of guidelines for consultation was reported by 54.9% of respondents. Of those interviewed, 79.8% knew about Health Technology Assessment. 95.5% reported they have heard of clinical audit and 98.9% knowing the concept of risk management. CONCLUSION: In our survey, an high value judgment about clinical governance was reported by medical managers. The lower attitudes towards the use of the tools of clinical governance highlights an important discrepancy with respect to knowledge and opinions, which becomes more evident in community care structures. Above and beyond training managers, it is also necessary to change training methods used on all health personnel, which should be oriented towards EBM in order to build an adaptable organizational climate.

Prevalence of HPV infection and genotype distribution in women from Africa seeking asylum in Puglia, Italy.

HPV type-specific distribution was evaluated in genital samples collected from 151 women from West Africa and Horn of Africa, living in the Asylum Seeker Center in Bari Palese (Italy), undergoing voluntary screening correlated with cytological abnormalities. HPV-DNA was assayed by Linear Array HPV genotyping test. HPV DNA was detected in 39.1 % of the women, 42.5 % of which had multiple infection and 69.5 % had high-risk HPV infection. Age-prevalence rates evidenced a peak of HPV infection in women ≤ 20 years of age (53.1 %). HPV 53 and 16 were the most common viral types (13.5 and 12.0 % respectively). Abnormal Pap test results were found in 4.4 % of women with known cytological result. Although a prevalence of HPV positive women higher in African than in European women was expected, the differing rate between residents and migrants African women must be investigated in future studies.

[Mandatory vaccination and health's right: the value of case law in the public health practice in Italy]. / Obbligo vaccinale e diritto alla salute: il valore della giurisprudenza nella pratica di sanità pubblica italiana.

In Italy there have been several court appeals registered, which have been driven by individual convictions or group actions or movements and were aimed at obtaining exemption from the obligation to comply with compulsory vaccinations required by law. The aim of the present paper is to provide a quick review of the sentences resulting from activating these disputes, in order to contribute to the debate on overturning compulsory vaccination. The Jurisprudence of the Italian Constitutional Court has repeatedly confirmed the judgment on the constitutionality of rules on obligation, clarifying that only where specific reasons exist that make vaccinating the individual dangerous may non-compliance with the rules on compulsory vaccination be justified. This is in contrast with the case law on enforcement of compulsory vaccination, through the temporary suspension of parental authority. Taking responsibility for promoting immunisation decisions away from Public Health Services and handing it to the courtroom is not advisable, given the very small benefit. The problem must be placed under the careful attention of the Health Service due to communicative implications, which can be serious during the transition from a compulsory system of immunisation to a voluntary one.

The burden of hospitalization related to diabetes mellitus: a population-based study.

BACKGROUND AND AIMS: To estimate the impact of diabetes and its complications, overall and in different age classes, on the likelihood of hospital admission for specific causes. METHODS AND RESULTS: We carried out a record-linkage analysis of administrative registers including data on 8,940,420 citizens in 21 Local Health Authorities in Italy. Individuals with pharmacologically treated diabetes (≥2 prescriptions of antidiabetic agents during the year 2008) were paired in a 1:1 proportion with those who did not receive such drugs (controls) based on propensity-score matching. Odds Ratios (ORs) of hospitalization for macro and microvascular conditions in individuals with diabetes as compared to controls were estimated. The system identified 498,825 individuals with diabetes pharmacologically treated (prevalence of 5.6%). Prevalence of diabetes in people aged <14 years, 14-39 years, 40-65 years, and ≥65 years was 0.1%, 0.6%, 6.4%, and 18.2%, respectively. Overall, 23.9% of subjects with diabetes and 11.5% of controls had had at least a hospital admission during 12 months for the causes considered. Diabetes increased the likelihood of hospitalization by two to six times for the different causes examined. In absolute terms, diabetes was responsible for an excess of over 12,000 hospital admissions per 100,000 individuals/year. CONCLUSION: Despite the availability of effective treatments to prevent or delay major complications, diabetes still places an enormous burden on both patients and the health care system. Given the continuous rise in diabetes prevalence both in middle-aged and elderly individuals, we can expect an additional, hardly sustainable increase in the demand for health care in the near future.

[From the struggle for freedom to the denial of evidence: history of the anti-vaccination movements in Europe]. / Dalla lotta per la libertà alla negazione dell'evidenza: storia dei movimenti anti-vaccinisti in Europa.

The 1853 Vaccination Act, adopted in England during XIX century, was the first law about compulsory vaccination in Europe. The Act caused a violent movement of opposition with the birth of Victorian anti-vaccination. The modern anti-vaccination movement was born in 1998 following a paper of Andrew Wakefield published in the Lancet. In this paper Wakefield illustrated a study of twenty patients and concluded that the administration of the MMR vaccine caused autism and some forms of colitis. The publication was later disowned by almost all authors. However the study of Wakefield caused a reduction of compliance to the anti-MMR vaccination in the United Kingdom, resulting in lower coverage and new outbreaks. The theorethical principles of anti-vaccinationists of 19th and 20th century were: the hypothesis that vaccines cause illnesses; the presence of toxic substances in the vaccine; the violation of freedom Personal and People's; the ineffectiveness of vaccinations. Moreover, anti-vaccinationists always refused the scientific methods and the peer-review of their scientific studies.

A study on the sexual and contraception behaviours of the pre-university students in Puglia (South-Italy).

INTRODUCTION: The aim of the present study is to determine attitude and associated factors towards the use of methods of protection/contraception. METHODS: In August 2008, a study was carried out using a self-administered standardised anonymous questionnaire. It was administered to school-leavers who were attending a study course at Bari University. RESULTS: The total number of questionnaires returned was 1091, the average age of the interviewed subjects was 19.6. Those declaring to have had sexual intercourse at least once was 88%. Of those sexually active, the average age at first intercourse was 16.8, and 75.2% stated that they had used some form of contraception on this occasion. The condom was the most popular method employed, followed by withdrawal and by contraceptive pills. Around 20% of the interviewees indicated that they used emergency post-coital contraception. DISCUSSION: The study results emphasise the importance of an effective teaching of the aspects of sex and relationship education before puberty.

[Nutrition prevention intervention for cancers: "Med-Food Anticancer Program"]. / L'intervento di prevenzione nutrizionale dei tumori: "Med-Food Anticancer Program".

Several studies recommend the Mediterranean diet and daily physical activity to prevent cancer development. These recommendations, however must be transformed into public health structured programmes, so that they assume operational effectiveness. The aim of the diet and lifestyle intervention called Med-Food Anticancer Program (MFAP) is to promote the Mediterranean diet and physical activity in the adult population. In particular; the target for participants in the intervention is the increased consumption of legumes, fish, whole grain bread and cereals, fruits and vegetables, and the decreased consumption of meat, cheese and foods of animal origin. At the same time, it is recommended to make at least ten thousand steps a day. Two studies have shown the effectiveness of MFAP.

[Pneumococcal polysaccharide immunization strategies in Italian regions]. / Strategie per l'offerta della vaccinazione anti-pneumococcica 23-valente nelle regioni italiane.

The aim of this study is to describe the immunization strategies for 23-valent pneumococcal vaccine in the Italian regions. Sixteen regions offer pneumococcal vaccine to elderly people and 18 regions to risk groups. Nine among them offer the vaccine free of charge and perform the call for immunization. Five regions created a database of the risk groups. Data about vaccination coverage are available for seven regions; in the other only the number of administered doses is collected yearly. Different immunization strategies may represent a determinant of health inequalities.

Communication skills in HPV prevention: an audit among Italian healthcare workers.

This study aims to investigate the knowledge, the attitudes and practices on HPV vaccination of health professionals of Mother and Child Service of Puglia Region (Italy). The study was conducted through a standardized questionnaire. Of 455 respondents, 74.2% judged HPV vaccine very important for immunization calendar. 88.9% did not believe that the administration of HPV vaccine implies consent to the initiation of sexual activity but 34.2% sustained that vaccine can give a false sense of protection against sexually transmitted diseases. 62.2% believed that boys should also be vaccinated. Skills necessary in the implementation of strategies in the promotion of health are partially inadequate and appropriate ongoing education should be carried out for health care workers.
