Human papillomavirus and vaccination: knowledge, attitudes, and behavioural intention in adolescents and young women in Italy

This study assesses knowledge, attitudes, and behavioural intention towards human papillomavirus (HPV) infection and vaccination in a random sample of 1348 adolescents and young women aged 14–24 years in Italy. A self-administered anonymous questionnaire covered demographics; knowledge about HPV infection, cervical cancer, and HPV vaccine; the perceived risk for contracting HPV infection and/or for developing cervical cancer, the perceived benefits of a vaccination to prevent cervical cancer, and willingness to receive an HPV vaccine. Only 23.3% have heard that HPV is an infection of the genital mucosa and about cervical cancer. Those older, with at least one parent who is a health care professional, with personal, familiar, or friendly history of cervical cancer, and having underwent a health checkup in the last year with information about HPV vaccination were significantly more knowledgeable. Risk perception scores (range: 1–10) of contracting HPV infection and of developing cervical cancer were 5.8 and 6.5. Older age, not having a parent who is a health care professional, having had a personal, familiar, or friendly history of cervical cancer, and need of additional information were predictors of the perceived susceptibility of developing cervical cancer. The vast majority professed intent to receive an HPV vaccine and the significant predictors were having at least one parent who is a health care professional, a high perceived risk of contracting HPV infection and of developing cervical cancer, and a high belief towards the utility of a vaccination for preventing cervical cancer. Knowledge about HPV infection and cervical cancer should be improved with more attention to the benefit of HPV vaccination.

Food handlers and foodborne diseases: knowledge, attitudes, and reported behavior in Italy.

The purpose of this study was to evaluate knowledge, attitudes, and behavior concerning foodborne diseases and food safety issues among food handlers in Italy. Face-to-face interviews were conducted within a random sample using a structured questionnaire. Of the 411 food handlers responding, 48.7% knew the main foodborne pathogens (Salmonella spp., Staphylococcus aureus, Vibrio cholerae or other Vibrio spp., Clostridium botulinum, hepatitis A virus), and this knowledge was significantly greater among those with a higher education level, in practice from a longer period of time, and who had attended education courses (P < 0.05). A vast majority (90.4%) correctly indicated those foods classified as common vehicles for foodborne diseases, and only 7.1% of food handlers were able to name five different food vehicles, each of which transmit one of the five pathogens. The proportion of those who were able to specify a food vehicle that transmitted hepatitis A virus was significantly higher for those with a higher educational level and with a longer food-handling activity. A positive attitude toward foodborne diseases control and preventive measures was reported by the great majority of food handlers, and it was more likely achieved by those who had attended education courses. This attitude was not supported by some of the self-reported safe practices observed for hygienic principles, because only 20.8% used gloves when touching unwrapped raw food, and predictors of their use were educational level and attending education courses. Results strongly emphasize the need for educational programs for improving knowledge and control foodborne diseases.

Preventable hospitalization and access to primary health care in an area of Southern Italy

BackgroundAmbulatory care-sensitive conditions (ACSC), such as hypertension, diabetes, chronic heart failure, chronic obstructive pulmonary disease and asthma, are conditions that can be managed with timely and effective outpatient care reducing the need of hospitalization. Avoidable hospitalizations for ACSC have been used to assess access, quality and performance of the primary care delivery system. The aims of this study were to quantify the proportion of avoidable hospital admissions for ACSCs, to identify the related patients socio-demographic profile and health conditions, to assess the relationship between the primary care access characteristics and preventable hospitalizations, and the usefulness of avoidable hospitalizations for ACSCs to monitor the effectiveness of primary health care.MethodsA random sample of 520 medical records of patients admitted to medical wards (Cardiology, Internal Medicine, Pneumology, Geriatrics) of a non-teaching acute care 717-bed hospital located in Catanzaro (Italy) were reviewed.ResultsA total of 31.5% of the hospitalizations in the sample were judged to be preventable. Of these, 40% were for congestive heart failure, 23.2% for chronic obstructive pulmonary disease, 13.5% for angina without procedure, 8.4% for hypertension, and 7.1% for bacterial pneumonia. Preventable hospitalizations were significantly associated to age and sex since they were higher in older patients and in males. The proportion of patients who had a preventable hospitalization significantly increased with regard to the number of hospital admissions in the previous year and to the number of patients for each primary care physician (PCP), with lower number of PCP accesses and PCP medical visits in the previous year, with less satisfaction about PCP health services, and, finally, with worse self-reported health status and shorter length of hospital stay.ConclusionThe findings from this study add to the evidence and the urgency of developing and implementing effective interventions to improve delivery of health care at the community level and provided support to the usefulness of avoidable hospitalizations for ACSCs to monitor this process.

HACCP and Food Hygiene in Hospitals Knowledge, Attitudes, and Practices of Food-Services Staff in Calabria, Italy

OBJECTIVES To determine adherence to Hazard Analysis and Critical Control Points (HACCP) methods and to evaluate knowledge, attitudes, and practices of food-services staff with regard to food hygiene in hospitals. DESIGN A survey. PARTICIPANTS Hospital medical directors and food-services staff of 36 hospitals in Calabria, Italy. METHODS A questionnaire about hospital characteristics, food-services organization, and measures and procedures for the control and prevention of foodborne diseases was sent to medical directors; a questionnaire about demographic and practice characteristics, knowledge, attitudes, and behaviors about control and prevention of foodborne diseases was sent to food-services staff. Multiple logistic regression analysis was performed. RESULTS Only 54% of the 27 responding hospitals were using the HACCP system and, of those using HACCP, 79% adopted a food-hygiene-practice manual; more than one half already had developed written procedures for food storage, personal hygiene, cleaning and disinfection; one half or less performed microbiological assessment of foods and surfaces. Of the 290 food-services staff who responded, 78.8% were aware of the five leading foodborne pathogens; this knowledge was significantly higher among those with a higher educational level and those who worked in hospitals that had implemented the HACCP system. Younger staff and those who had attended continuing educational courses about food hygiene and hospital foodborne diseases had a significantly higher knowledge of safe temperatures for food storage. A positive attitude toward foodborne-diseases prevention was reported by the great majority, and it was significantly higher in older respondents and in those working in hospitals with a lower number of beds. Only 54.9% of those involved in touching or serving unwrapped raw or cooked foods routinely used gloves during this activity; this practice was significantly greater among younger respondents and in those working in hospitals using HACCP. CONCLUSION Full implementation of the HACCP system and infection control policies in hospital food services is needed.

Efficacy of Pneumococcal Vaccination in Children Younger Than 24 Months: A Meta-Analysis

CONTEXT. Pneumococcal conjugate bacterial vaccines that are able to prevent invasive disease and mucosal infections have been developed. OBJECTIVE. A meta-analysis of published data from trials on pneumococcal conjugate vaccine was performed to determine the efficacy in reducing the incidence of invasive disease caused by Streptococcus pneumoniae, pneumonia, and acute otitis media in healthy infants younger than 24 months. METHODS. A systematic search of the literature was conducted. Controlled clinical trials had to compare the protective efficacy of the pneumococcal conjugate vaccine in reducing the incidence of invasive disease caused by S pneumoniae, pneumonia, and acute otitis media in healthy infants with placebo or control vaccines. Information was extracted by using a standardized protocol. RESULTS. The efficacy of pneumococcal conjugate vaccine in the reduction of invasive pneumococcal disease was 89% involving vaccine serotypes in both the intention-to-treat and per-protocol analyses and ranged from 63% to 74% for all serotypes. The efficacy to prevent acute otitis media sustained by vaccine serotypes was 55% in the intention-to-treat and 57% in the per-protocol analyses, whereas it was 29% to prevent otitis involving all serotypes in the per-protocol analysis. Finally, in the intention-to-treat and per-protocol analyses, the efficacy to prevent clinical pneumonia was 6% and 7%, respectively, whereas for the prevention of radiograph-confirmed pneumonia it was 29% and 32%, respectively. CONCLUSIONS. The pneumococcal conjugate vaccine produces a significant effect regarding prevention of invasive pneumococcal disease. Results on prevention of otitis or pneumonia have been less striking, but considering the high burden of these diseases in infants, even a low efficacy has potential for tremendous impact on the health of infants in developing and industrialized countries.

Vancomycin Resistance and Antibiotic Susceptibility of Enterococci in Raw Meat

The purpose of this study was to investigate antimicrobial resistance, in particular to vancomycin, of enterococci in samples (100) of meat (beef, chicken, turkey, lamb, and pork) sold in retail outlets of Catanzaro (Italy). Enterococci were identified to the species level. Antimicrobial susceptibility tests for a large spectrum of antibiotics including glycopeptides were performed by the disk diffusion method. Kappa statistic was used to evaluate associations of resistance to vancomycin with other antimicrobials. Enterococci were isolated from 45% of the samples, mostly from chicken meat (65.4%). Overall, 29% of samples were contaminated by vancomycin-resistant enterococci (VRE), whereas among those positive they represented 64.4% of isolates. Higher prevalence of vancomycin resistance was found in chicken samples (76.5%). The overall resistance to teicoplanin (TRE) was 30%, whereas among those positive, TRE represented 66.7% of isolates. The most frequent isolates were Enterococcus faecium (35.6%) and Enterococcus faecalis (33.3%). Resistance to vancomycin and teicoplanin was observed in 75% and 78.5% of E. faecium, and in 40% and 46.7% of E. faecalis, respectively. Most strains were susceptible to ampicillin (80%), while 88.9% were resistant to methicillin. The most effective antimicrobials were imipenem (73.3% susceptible) and rifampin (80%). The highest prevalence of resistance was for streptomycin (88.9%), tetracycline (84.4%), and erythromycin (75.6%). Resistance to vancomycin was significantly associated to methicillin, teicoplanin, erythromycin, tetracycline, and chloramphenicol. Further investigations about enterococcal colonization and infections in community and hospital subjects are needed.

Meta-analysis of residential exposure to radon gas and lung cancer

OBJECTIVES To investigate the relation between residential exposure to radon and lung cancer. METHODS A literature search was performed using Medline and other sources. The quality of studies was assessed. Adjusted odds ratios with 95% confidence intervals (CI) for the risk of lung cancer among categories of levels of exposure to radon were extracted. For each study, a weighted log-linear regression analysis of the adjusted odds ratios was performed according to radon concentration. The random effect model was used to combine values from single studies. Separate meta-analyses were performed on results from studies grouped with similar characteristics or with quality scores above or equal to the median. FINDINGS Seventeen case-control studies were included in the meta-analysis. Quality scoring for individual studies ranged from 0.45 to 0.77 (median, 0.64). Meta-analysis based on exposure at 150 Bq/m3 gave a pooled odds ratio estimate of 1.24 (95% CI, 1.11-1.38), which indicated a potential effect of residential exposure to radon on the risk of lung cancer. Pooled estimates of fitted odds ratios at several levels of randon exposure were all significantly different from unity--ranging from 1.07 at 50 Bq/m3 to 1.43 at 250 Bq/m3. No remarkable differences from the baseline analysis were found for odds ratios from sensitivity analyses of studies in which > 75% of eligible cases were recruited (1.12, 1.00-1.25) and studies that included only women (1.29, 1.04-1.60). CONCLUSION Although no definitive conclusions may be drawn, our results suggest a dose-response relation between residential exposure to radon and the risk of lung cancer. They support the need to develop strategies to reduce human exposure to radon.

Knowledge, Attitudes, and Practices of Avian Influenza, Poultry Workers, Italy

We asked Italian poultry workers about knowledge, attitudes, and practices regarding avian influenza. It was perceived to be a low occupational hazard, and wearing protective equipment and handwashing were not routine practices. Knowledge of transmission and preventive measures should be improved. Employers and health professionals should provide more effective information.

Public Knowledge, Attitudes, and Experience Regarding the Use of Antibiotics in Italy

Background The objectives of the study were to investigate the level of knowledge, attitudes, and behaviors regarding antibiotics of the general population in Italy, and to assess the correlates of these outcomes of interest. Methods A cross-sectional survey was conducted on a random sample of 630 parents of students attending nine randomly selected public primary and secondary schools. A self-administered questionnaire included questions on demographic characteristics, knowledge about antibiotic use and resistance, attitudes and behaviors towards antibiotic use, and sources of information. Results A total of 419 parents participated. Only 9.8% knew the definition of antibiotic resistance and 21.2% knew when it was appropriate to use antibiotics. Respondents with higher education, employed, with a family member working in the health care sector, and with no need for additional information on antibiotics were more likely to know the definition of antibiotic resistance. One third (32.7%) self-classified them as users of self-medication with antibiotics and those with a lower self-rated health status, who did not use the physician as source of information on antibiotics, and who have attended a physician in the last year were more likely to use self-medication. One-fourth (22.7%) of those who had never been self-medicated would be willing to take an antibiotic without a prescription of a physician. Respondents were more likely to be willing to take antibiotics without a prescription if they were under 40 years of age, if they had a lower self-rated health status, if they did not know that antibiotics are not indicated for treating flu and sore throat, and if they knew that antibiotics are not indicated for treating colds. Conclusions The survey has generated information about knowledge, attitudes, and behaviors regarding antibiotics in the general population and effective public education initiative should provide practical and appropriate means to change their behavior.

Consumers and foodborne diseases: knowledge, attitudes and reported behavior in one region of Italy

A survey was conducted to investigate knowledge, attitudes and related behavior on foodborne diseases and food-handling practices among consumers in one region of Italy. A self-administered questionnaire was offered to a random sample of mothers of children attending public schools. Of the 394 responding mothers, 36% knew about all the six foodborne pathogens investigated but only 11.1% correctly indicated six related different food vehicles; education level was a predictor of this knowledge. A positive attitude towards foodborne disease control, significantly higher in older and more educated women, was reported by the great majority, who agreed that improper storage of food represents a health hazard (95.7%), that washing hands before handling unwrapped raw or cooked food reduces the risk of food poisoning (93.2%), and that the awareness of the temperature of the refrigerator is crucial in reducing risk of food poisoning (90.1%). Only 53.9% reported washing hands before and after touching raw or unwrapped food and 50.4% reported using soap to wash hands. A total of 75.6% clean kitchen benches after every use and 81.1% use hot water and soap for this purpose. Only 25.6% thaw food in the refrigerator and 49.9% put leftovers in the refrigerator soon after meals. Washing hands before and after touching unwrapped food was significantly higher in women living in larger families and who had been informed by physicians about foodborne diseases. Educational programs and the counseling efforts of physicians, particularly focused to less educated subjects, are greatly needed.
