[Adhesion the vaccination against HPV in ASL of L'Aquila]. / Adesione alla vaccinazione contro l'HPV nella ASL dell'Aquila.

Sexually transmitted human papillomaviruses (HPVs) are responsible for anogenital infections and tumours. Types 16 and 18 cause 70% of cervical carcinomas, the incidence of which is higher among young women. The aim of this study was to evaluate the propensity of mothers to have their 12-year-old daughters vaccinated against HPV and identify the variables that may influence their agreement, such as their kowledge of HPV and its relationship with cervical cancer. A 17-item questionnaire was anonymously administered to 312 mothers of girls born in 1997 who were invited to undergo vaccination by their local health authority. The results were analysed using the chi-squared test and STATA 9 statistical software. The analysis showed that 69% of the mothers had had their daughters vaccinated, that most of them know about HPV but only 20% clearly understood the relationship between HPV and cancer Acceptance of the vaccination seems to be associated more with a general predisposition to vaccinate than with a knowledge of HPV and its causal relationship with cervical carcinoma. This indicates a need for educational/ information programmes before and during the vaccination cycle.

Vaccination coverage in healthcare workers: a multicenter cross-sectional study in Italy.

INTRODUCTION: In recent years, a phenomenon known as "vaccine hesitancy" has spread throughout the world, even among health workers, determining a reduction in vaccination coverage (VC).A study aimed at evaluating VC among healthcare workers (HCWs) in 10 Italian cities (L'Aquila, Genoa, Milan, Palermo, Sassari, Catanzaro, Ferrara, Catania, Naples, Messina) was performed. MATERIALS AND METHODS: Annex 3 of the Presidential Decree n. 445 of 28 December 2000 was used to collect information on the vaccination status of HCWs. The mean and standard deviation (SD) were calculated with regard to the quantitative variable (age), while absolute and relative frequencies were obtained for categorical data (sex, professional profile, working sector, vaccination status). The connection between VC and the categorical variables was evaluated by chi-square method (statistical significance at p < 0.05). The statistical analyses were performed by SPSS and Stata software. RESULTS: A total of 3,454 HCWs participated in the project: 1,236 males and 2,218 females.The sample comprised: physicians (26.9%), trainee physicians (16.1%), nurses (17.2%) and other professional categories (9.8%). Low VC was generally recorded. Higher VC was found with regard to polio, hepatitis B, tetanus and diphtheria, while coverage was very low for measles, mumps, rubella, pertussis, chickenpox and influenza (20-30%). CONCLUSIONS: This study revealed low VC rates among HCWs for all the vaccinations. Measures to increase VC are therefore necessary in order to prevent HCWs from becoming a source of transmission of infections with high morbidity and/or mortality both within hospitals and outside.

[Evaluation of cognitive requirements of parents consumers attending vaccination offices]. / Valutazione dei fabbisogni conoscitivi dei genitori utenti degli Uffici di Vaccinazione.

To vaccinate the majority of population it is essential a strong cooperation with parents (users) which have to be correctly informed through an efficient communication system. The present analysis aims at elucidating parental background knowledge and information sources on vaccination problems. We selected 387 parents from ASL vaccination offices in L'Aquila, Avezzano-Sulmona and Pescara. Two groups have been identified: the first group included parents dealing with the first vaccination of their child, parents in the second group already experienced the vaccination tool. The two groups have been tested with a 17 items questionnaire. Results analysis evidenced a reasonable trust in the validity of received information and a fair level of topic knowledge. Our results show that the organizative and cultural effort put on by Public health operators improved awareness and participation to vaccination program. Still a big effort has to be devoted to disadvantage group of population's mainly low-level education groups and new immigrants. Thus it would be wise to promote informative actions even through the media to increase the basic knowledge on vaccine strategies

Spontanuous Demand For Meningococcal B Vaccination: Effects On Appropriateness And Timing.

When the meningococcus B vaccine was introduced into Italy in 2017, it was recommended for newborns based on national epidemiological data indicating that they were at greater risk. However, the vaccination service of the local health authority of L'Aquila had already been receiving spontaneous parental requests to provide vaccination for children in lower-risk age groups from the beginning of 2016. We therefore decided to use a self-administered questionnaire in order to investigate the parents' socio-demographic data; their children's history of other recommended vaccinations (against measles, mumps and rubella, varicella, meningococcus C and, for females, human papilloma virus); the information sources concerning meningococcal vaccination; and the timing of its administration. The questionnaire was completed by 565 parents, and the results showed that the requests mainly came from the parents of children aged 5-11 years. The children whose mothers had received a high school education and were >35 years old were more likely to have received the first dose after the age of one year and to have perceived pain at the inoculation site, and less likely to have experienced mild general reactions. The requests were mainly trigged by the recommendations of healthcare professionals, and the overloading of the vaccination service led to delays in the administration of the doses after the first. The delays (reported by 74.07% of the parents) were mainly due to organisational problems in the service itself, which led 61.52% of the doses being more appropriately administered by staff working as private physicians inside public health facilities, albeit at extra cost. These findings indicate that organisational factors and excessive demand had a considerable impact on both the efficacy of the immunisation and its appropriateness.

Attitudes towards compulsory vaccination in Italy: Results from the NAVIDAD multicentre study.

BACKGROUND: Vaccine hesitancy is a considerable issue in European countries and leads to low coverage rates. After a long debate, Italy has made vaccination mandatory for admission to its schools. METHODS: In the NAVIDAD study (a cross-sectional multicentre study), a 63-item questionnaire was administered to 1820 pregnant women from 15 Italian cities. The questionnaire assessed the interviewee's opinion on mandatory vaccines, as well as their socioeconomic status, sources of information about vaccines, confidence in the Italian National Healthcare Service (NHS), and intention to vaccinate their newborn. RESULTS: Information sources play a key role in determining the opinion on restoration of mandatory vaccines; in particular, women who obtained information from anti-vaccination movements are less likely to accept the vaccines (OR: 0.35, 95% CI: 0.21-0.58, p < 0.001). Women who had confidence in healthcare professional information agreed more on mandatory vaccination than did the other women (OR: 2.66, 95% CI: 1.62-4.36, p < 0.001); those who perceived that healthcare professionals have economic interest in child immunization and who declared that healthcare providers inform only on vaccinations benefits not on risks were less likely to agree on compulsory vaccination (OR: 0.66, CI 95%: 0.46-0.96, p = 0.03; OR: 0.66, CI 95%: 0.46-0.95, p = 0.03, respectively). CONCLUSION: Information sources and confidence towards health professionals are the main determinants of acceptance of mandatory vaccine restoration. To increase the acceptability of the restoration and reduce vaccine hesitancy, these aspects need to be strengthened.

Hygiene in dental practices.

AIM: The aim of this study was to investigate the hygienic quality of dental practices on the basis of the self-awareness expressed by dentists respondents to a self-reported questionnaire about the health/hygiene characteristics of practice, the knowledge of biologic/toxicological risks and the preventive procedures and devices improvements in professional practice. MATERIALS AND METHODS: Of the 127 practitioners contacted, 108 (85%) agreed to participate. The knowledge of infective risks was self- evaluated as good only in 24%: even if vaccinated, most of the dentists (57%) considered HBV the main infective agent to fear, not giving the same importance to the air-borne transmission of diseases. The presence of a single dental unit per surgery (90%) was considered an index of good health/hygiene education but, in spite of the use of disposable gloves, caps and masks, the dentists do not always change their coats or wash their hands between patients yet. The management of dental instruments can be considered efficient as long as they are sterilised in an autoclave (97%) and undergo periodic sterilization efficacy tests (76%). RESULTS AND CONCLUSION The results indicate a good structural and organisational status, but there is the need for continuous education concerning the prevention of cross-infections.

Dental caries and bone mineral density: a cross sectional study.

AIM: The relationship between bone mineral density (BMD), age and dental caries has been studied. Quantitative ultrasonography (QUS) is an economic, non invasive, and reproducible method for measuring both bone mineral density and bone elasticity in growing subjects in large populations. METHODS: This study evaluated the relationship between BMD and prevalence of dental caries (Decayed Missing Filled Tooth - DMFT) in 540 healthy adolescent with mean age 12.3 years, age range 10 to 15 years, resident in two provinces in south Italy. BMD was measured using QUS by calculating the speed of sound (m/s) on the last four fingers of the non dominant hand, with the estimate thus obtained being defined as the AD-SoS (Amplitude-Dependent Speed of Sound and categorised as AD-SoS < or = 1900 m/s and AD-SoS > 1900 m/s). Occurrence of dental caries was defined using the DMFT index (DMFT=0 and DMFT > 0). RESULTS: The results of the multifactorial analysis, carried out with logistic model, confirms the expected statistically significant association between response (DMFT) and explicative variables -- AD-SoS (P < 0.006) and Age (P < 0.004). CONCLUSION: Greater bone mineralisation (AD-SoS1900 m/s) and younger age (Age < or =12 years) are dental caries prevention factors: the probability to have caries for the subjects in such conditions is 0.34, about the half of that recorded in the subjects with lower bone mineralisation and older age (0.62).

Cytogenetic biomonitoring of workers from laboratories of clinical analyses occupationally exposed to chemicals.

A cytogenetic monitoring study was carried out on a group of workers in clinical analysis laboratories to investigate the risk of occupational exposure to chronic low levels of chemicals.Thirty-four clinical laboratories have been involved in the study. In these laboratories, toxicants and analytical procedures utilized have been characterized. The individual occupational exposure of workers was assessed by use of a questionnaire concerning the chemical substances utilized. About 300 different chemicals have been identified. Cytogenetic analyses (chromosomal aberration and micronucleus tests) were carried out on a strictly selected group of 50 workers enrolled from these laboratories and compared to 53 controls (healthy blood donors) matched for gender and age. The exposed group shows a significantly higher frequency of genetic damage than the control group. Both chromatid and chromosome aberration frequencies in workers appear significantly higher than in controls. Similarly, comparison between micronucleated cells rates of exposed and unexposed groups show significantly higher frequencies of binucleated cells with micronucleus (BNMN) and of total micronuclei (MN tot) in workers than in controls.

[Laboratory diagnosis: correlated health and environmental risks]. / La diagnostica di laboratorio: rischi sanitari e ambientali correlati.

Method description and initial results of a study to assess risks to health sector workers and environment due to chemical agents used and waste products generated in diagnostic clinical chemical laboratories, and image diagnostic testing. A survey was conducted of the methods and agents used and their toxicological classification, the number of workers exposed and an analytical profile of the waste produced. The assessment of risk to workers was based on cytogenetic tests (chromosome aberrations and micronuclei); the assessment of environmental risk from waste disposal was based on tests on plant systems.

[Knowledge of nursing students about occupational biological risk]. / Conoscenze degli allievi infermieri sul rischio biologico occupazionale.

The health care staff is potentially more exposed to contract infectious diseases at work. This risk becomes true if the DPI are not utilized and the operators don't work according to the standard protocol, and, with regard to the health care students, they begin their clinical training without the right knowledges. To verify the adequacy of knowledges and the consequent behaviours we effected a study among the students at first year of the D. U. for nurses in the University of L'Aquila, through a questionnaire. It came out many gaps of knowledges about the standard practice and about the Universal Precautions in about 20% of the interviewed.

[Low birth weight, life style of mothers during pregnancy and chlorinated drinking water]. / Basso peso alla nascita, abitudini di vita delle madri in gravidanza e consumo di acque sottoposte a clorazione.

Numerous environmental factors such as smoking habits, alcohol intake, economic and social status, and by-product chlorination present in drinking water can determine adverse pregnancy outcomes like a low weight birth, small for gestational age or preterm delivery. In 1998 the Italian Ministry of University and Scientific Technological Research (MURST) has financed a multicentric study in order to evaluate the association between exposure to by-products chlorination in drinking water during pregnancy and adverse pregnancy outcomes at birth such as preterm delivery and low birth weight. We describe the socio demographics characteristics, personal habits and the health status during pregnancy and exposure to the VOX of 171 women recruited from the Research Unit of Rome and L'Aquila. A case control study with incident cases was performed. Exposure to Chlorination By Products (CBP) and confounding factors for studied outcomes, were assessed by a validated questionnaire. At the same time, collection and analysis of 124 tap water samples were carried out directly at women's home. No association was found between CBPs level and low birth weight or preterm delivery. We found an excess risk statistically significantly between preterm delivery and hypertension (OR = 5.06; IC 95% = 1.70-15.44) an excess risk statistically significantly between low birth weight and smokers (OR = 3.43, IC 95% = 1.15-10.26). The CBPs levels were rather low (range cases = 0.09-6.28 microg/L; range controls = 0.01-6.44 microg/L). The results confirm the literature data and the validity of the epidemiological method adopted. The low CBPs levels, under the Law level, are probably imputable to the good quality of sorgive waters. Considering the CBPs level temporal variability in chlorinated waters, is to be hoped a careful and continues surveillance of the CBPs spike levels for better exposure assessment.

Survey of nursing knowledge on bioterrorism.

With the aim of identifying intervention programmes within the framework of basic and permanent nursing training, we evaluated the knowledge of 187 nurses and nursing students concerning biological emergencies. A questionnaire was used to identify their knowledge of the pathogens that may be used in a terrorist attack and measures for containing them, and their perception of the danger to public health. Analysis of the responses showed that the undergraduates studying for the Triennial Degree were the best informed, and those studying for the specialist degree were the least informed. The question relating to the precautions adopted against transmission of Bacillus anthracis was the most predictive of the total score because it was the only one with a substantial number of correct answers (79/187). It seems that the information derived more from the generalist media than from academic training. We conclude that there is a need to train qualified personnel capable of responding to a possible emergency in terms of both preventive and interventional medicine.
