Incremental net benefit of wearable devices for home monitoring of chronically ill patients

Background

Hospital overcrowding is a growing problem worldwide. Studies demonstrated that up to 40% to 67% of hospitalizations of residents in nursing homes may be avoidable, causing health and economic damages. Furthermore, research shows that for non-critical patients there are arguably no differences between home and hospital recovery in terms of health outcomes, with a preference for home settings in most patients. During COVID-19 pandemic, telemedicine and homecare increased its range of possible intervention, allowing efficient and cost-effective processes of care. Transdermal sensors are indeed a cheap and easy to use alternative to conventional instruments, allowing a continuously operative and ready-to-use tool to care providers. This systematic review aims to map the application fields of these technologies, demonstrating their accuracy and assessing their cost-effectiveness in chronically ill home-assisted patients.

Methods

Articles were retrieved from Scopus, Web of Science, and PubMed. The dominance ranking matrix (DRM) tool was applied to allow a qualitative synthesis of the studies. Incremental net benefits (INBs) were estimated and meta-analysis was implemented to pool INBs across studies. A comparison between wearables and conventional tools accuracy was simultaneously carried out through a literature review.

Results

The database search identified 1156 publications of which six articles were considered eligible for the meta-analysis. According to DRM, 80% of evaluated studies showed the cost-effectiveness of wearable devices. The pooled INB of wearables over conventional measurement was estimated at US$1280 (95% CI US$952 - US$2849). In 85% of evaluated wearables the accuracy resulted comparable to conventional measurement tools.

Conclusions

Wearables performances resulted as accurate as conventional methods and their application cost-effective. A continuous measurement of parameters may relate to a better process of care for chronically ill outpatients.

Key messages

• Wearables are a cheap and accurate alternative to conventional life parameters measurement tools.

• Technology evolution might soon reduce the pressure on hospitals, changing the care process of chronically ill outpatients allowing continuous evaluation of their health status.

Flu shot in the era of COVID-19 vaccination: findings from a research hospital of Rome

 

Influenza represents a major burden for public health. Healthcare workers (HCWs) are a priority target group for flu vaccination. During the COVID-19 pandemic, when SARS-CoV-2 vaccines were not yet available, susceptibility to influenza vaccination especially by HCWs increased. The aim of this study is to analyze the flu vaccination coverage among HCWs and to study which factors affected their adherence given the concomitant COVID-19 vaccination. The retrospective study was conducted in an Italian research hospital from October 2021 to January 2022. A total of 7,048 individuals was included. Age class, gender and job category variables were analyzed. Statistically significant differences among groups were tested through χ2 test. Univariate and multivariate analyses (p < 0,005) were performed to assess differences towards vaccination attitude. The flu vaccination coverage rate was 24.6%. Among the selected job categories, 29.8% of physicians, 19.9% of nurses and 19.7% of other HCWs were vaccinated with a statistically significant decrease (p < 0.001) across all categories respect with the last campaign. The findings of the logistic regression depicted that the 40-59 years old age class, compared with the youngest age class (OR 1.30, 95% CI 1.12-1.43) as well as being physician (OR 2.79, 95% CI 1.87-3.41) with the respect to being nurses, had a higher adherence to vaccination. Interestingly, being male, is associated with a statistically significant reduction (OR 0.71, 95% CI 0.59-0.87) in vaccination uptake. Study findings showed a several decline in the flu vaccination coverage comparing with previous campaigns, probably due to the concomitant administration of the booster dose against SARS-CoV-2. This alarm should not be underestimated and requires timely and innovative organizational approaches (i.e., combined vaccine). Further studies are needed to analyze the reasons for this poor adhesion and the strategies to be adopted to increase the awareness of the HCWs.

Key messages

• Reaching high coverage rates and restore a positive trend for the future campaign for flu vaccination it is essential strategy to protect HCWs themselves, their patients and the hospital community.

• Decision-makers should implement consistent communication strategies to lessen vaccine hesitancy among HCWs.

Walk the path of cervical cancer elimination in Italy: current scenario and shared recommendations

Issue/problem

In 2020, the World Health Organization (WHO) called for the elimination of cervical cancer. In order to get it, vaccination against Human Papillomavirus (HPV), screening of cervical cancer and treatment of high-grade cervical disease and cancer must be implemented at country level.

Description of the problem

Italy has implemented HPV vaccination and cervical cancer screening for many years. Nevertheless, nationwide data show that both vaccination coverage and adherence to screening programs are unsatisfactory as compared to the WHO 90 and 70 targets, namely 90% of girls fully vaccinated by the age of 15 years and 70% of women screened with a high-performance test (i.e., HPV-DNA test) by age 35 and again by 45.

Results

In order to address the progress of vaccination and screening at regional level in Italy, a project was conducted in 2021-2022 in order to collect data on relevant indicators and issues. In particular, information was collected on both coverage indicators (for both vaccination and screening) adherence (for screening) and history and characteristics of the vaccination offer (e.g., targets, gratuity) and of screening (e.g., presence of clinical pathways, type of tests used). Collected data were shared with a multidisciplinary panel of experts on HPV-related diseases to issue recommendations to foster the elimination of cervical cancer in Italy. For this purpose, a survey was also conducted to identify potential actions in respect to vaccination, screening and treatment.

Lessons

A great heterogeneity across Italian regions was observed. The following actions were identified to implement vaccination, screening and treatment: educational campaigns, reminders and active calls for both vaccination and screening and more interoperability of data and definition of clinical pathway involving a multidisciplinary medical team for the proper management of all HPV-related diseases.

Key messages

• Actions are requested at national level to achieve the goals set by the global strategy for cervical cancer elimination with respect to vaccination, screening and treatment.

• Actions identified to foster cervical cancer elimination in Italy includes educational campaigns, reminders and active calls, better interoperability of data and integrated medical team.

Combined Overview on Diverticular Assessment:a new score for the management of diverticular disease

Background

Diverticulosis is increasing worldwide as a public health problem. The Combined Overview on Diverticular Assessment (CODA) score, merging Diverticular Inflammation and Complication Assessment (DICA) and few clinical parameters, may reliably predict the occurrence of acute diverticulitis and surgery due to complications. Thus, the aim of the study is to confirm the value of DICA classification and to develop and validate the CODA endoscopic-clinical score.

Methods

A number of 2198 patients, at the first diagnosis of diverticulosis/diverticular disease were enrolled in a multicentre, prospective, international cohort study. Participants were scored according to DICA classifications. A 3-year follow-up was performed. Survival methods for censored observation were used to develop and validate the CODA score for predicting diverticulitis and surgery.

Results

The 3-year cumulative probability of diverticulitis and surgery was ≤4%, and ≤0.7% in CODA A; <10%and <2.5% in CODA B; >10%and >2.5% in CODA C, respectively. The 3-year cumulative probability of diverticulitis and surgery was of 3.3% (95% CI 2.5% to 4.5%) in DICA 1, 11.6% (95% CI 9.2% to 14.5%) in DICA 2 and 22.0% (95% CI 17.2% to 28.0%) in DICA 3 (p < 0.001), and 0.15% (95% CI 0.04% to 0.59%) in DICA 1, 3.0% (95% CI 1.9% to 4.7%) in DICA 2 and 11.0% (95% CI 7.5% to 16.0%) in DICA 3 (p < 0.001), respectively. The CODA score showed optimal discrimination capacity in predicting the risk of surgery in the development (cstatistic: 0.829; 95%CI 0.811 to 0.846) and validation cohort (c-statistic: 0.943; 95% CI 0.905 to 0.981).

Conclusions

DICA endoscopic classification was confirmed to have a significant predictive value in terms of acute diverticulitis occurence/recurrence and risk of surgery. CODA score could provide a new risk stratification tool useful for everyday clinical practice and also with a significant public health impact in terms of treatment effectiveness and decision making.

Key messages

• DICA endoscopic classification of diverticular disease is a clear predictor of the outcome of diverticulosis/diverticular disease.

• The CODA score, combining DICA and few clinical parameters, may reliably predict the occurence of acute diverticulitis and surgery due to complications.

Comparison of two home-based polysomnography tools for OSAS diagnosis: a cost-minimization analysis

 

Obstructive sleep apnoea syndrome (OSAS) is an underdiagnosed chronic disease with a high prevalence in adults. It is becoming an important social problem since it is associated with a significant adverse impact on quality of life and life expectancy. Overnight polysomnography, performed in a sleep laboratory (LabPSG), is considered the diagnostic standard. Home complete PSG (HoPSG) could represent an alternative to LabPSG for patients who want to avoid the overnight stay at a sleep center. The aim of this study was to assess the economic impact of two alternative HoPSG diagnostic techniques in the diagnosis of OSAS: the standard one versus the telemonitoring approach. The observational study was designed as a cost-minimization analysis adopting a healthcare perspective. The time horizon was 6 months (January 2021 - June 2021), thus no discounting was necessary. Direct medical costs, expressed in 2021 euros, were estimated through a micro-costing method while indirect costs were quantified adopting the Human Capital Approach. To explore the uncertainty of critical parameters, a one-way sensitivity analysis was run. Considering the direct costs, the telemonitoring HoPSG was estimated to cost around €55 less than the standard approach. The cost savings sharply increases taking into account the indirect costs that amounted to €90 million and €365 million for the telemonitoring and the standard approach, respectively. Sensitivity analyses results did not significantly differ from the base-case scenario. The diagnosis of OSAS is presently time-consuming, labor-intensive and costly. The adoption of digital health solutions as telemedicine has the potentiality to ease the diagnosis, to improve the access to health services, to reduce both direct and indirect costs, and to enhance the efficiency of healthcare facilities becoming a crucial tool in addressing the actual public health challenges.

Key messages

The telemonitoring Home complete polysomnography is cost-saving compared with the standard approach. Telemedicine has the huge potential to overcome public health challenges as increases in chronic disease in an ageing society and the associated burden in healthcare costs.

Planetary health research: insights from The Lancet Planetary Health original articles

Background

In 2017, the Lancet group launched The Lancet Planetary Health to promote the dissemination of research conducted in this field. Planetary health was also extensively discussed during the World Congress on Public Health 2020, which underlines the strategic importance recognized to this topic by experts and researchers active in public health at an international level. The aim was to investigate the role of public health university departments in the field of planetary health.

Methods

The Lancet Planetary Health database was queried from the inception to February 2021, to retrieve original articles or reviews whose first and/or last author was affiliated to a University Department of Public Health worldwide. We used the twenty-six EUPHA operational sections to define the research areas of the identified articles. The following data were extracted: study design, EUPHA area, research question, topic, identified gaps in the literature, and key concepts.

Results

Out of 543 entries, 44 original articles and reviews were included. Thirty-two percent studies were conducted in Asia, 20% in America, 13% in Europe, 8% in Oceania, 4% in Africa while 23% in a multicentric global context. The area investigated was mainly environmental and health (68%) followed by infectious disease control (14%). Collaboration across different disciplines is highly present in the authorships. Regarding the study design, 30% of the included articles were cohort studies.

Conclusions

From 2017 till February 2021, the number of studies performed by public health researchers published on The Lancet Planetary Health is gradually increasing.

Since published articles take advantage of the typical research methods and topics of public health and environmental health research, public health university departments can contribute to planetary health science if they seek transdisciplinary collaboration and adopt a planetary health vision.

Promoting food literacy in type 2 diabetes: a systematic review

Background

Diabetes is one of the major global health threats whose burden is sharply increasing. Food literacy is proved to be relevant to optimize self-management in diabetic patients. The present review aims to map the current literature on educational interventions to promote food literacy in type 2 diabetes, with a particular focus on the concept of patient engagement.

Methods

Five databases were queried using the Population-Intervention-Context-Outcome (PICO) model. Individual study quality was assessed using the Quality Criteria Checklist for primary research provided by the American Diabetes Association. Data were summarized using descriptive statistic and a comparison between intervention carried out by a multidisciplinary team versus a single professionist was performed adopting a Chi-square test (p &lt; 0.05 was deemed as statistically significant).

Results

Of 1580 articles, 28 were finally included. Outcome categories were narratively labelled as “clinical”, “psychological”, “behavioural” and “literacy”. When the provider was a multidisciplinary team (25% of studies) improvement in self-management occurred in 86% of cases while in single-provider intervention the percentage was 71%, but the difference was not significant (p = 0.45). In the 10.7% of articles the use of technologies was reported, but generically descripted as the use of webpages, email or social media. Globally, an improvement in food literacy was reported in 75% of the interventions.

Conclusions

Nowadays, the use of a technology proxy is recognized as an efficient support in boosting patients' education, but the evidence in improving food literacy is scarce and difficult to compare. Public health programs improving food literacy are effective at different levels. These findings should encourage decision makers to allocate resources in this kind of programs.

Key messages

Engaging people in the management of their disease by increasing food literacy level may represent a first step to reach the “health in all policies” approach. When planning a public health intervention, allocating resources for improving individual’s education is essential to achieve better health outcomes.

Artificial Intelligence and Urban health: a step forward to the achievement of SDGs

The Sustainable Development Goals (SDGs) recognized the transformative power of urbanization with a dedicated goal (SDG11) focused on cities. This represents a pivotal first step to empower cities, also technologically, enabling new levels of intelligence and showing the need to become smarter. Artificial Intelligence (AI) and smart cities bring a multidisciplinary, integrated approach, examining how the digital and physical worlds are converging. The AI-based algorithms are overcoming the provision of urban services entering the realms of urban governance, planning, health, and safety. The aim of this study is to review how digital technologies and AI-based algorithms can influence and transform urban health. A scoping review of the literature was conducted using the Population, Concept, Context (PCC) framework to formulate the research question. A comprehensive search strategy will be implemented according to the PRISMA Extension for Scoping Reviews (PRISMA-ScR). Major electronic databases were queried combining specific keywords. In addition, the search was completed by a snowball-search to identify missing articles. Out of a total of 1150 publications, 8 were identified as relevant to the research question. Among these articles, 43% and 35% reported findings from Europe and North America respectively. Evidence from the literature primarily focuses on the integration of smart city networks (sensor, people, business), based on AI, and urban health with different impacts on the health conditions of urban population over time. Public health plays major roles in urban planning sharing jointly common missions and perspectives. The advent of smart cities supported by AI can have an impact on public health, transforming urban life, with important consequences for physical, mental, and social well-being. AI applications in urban health could support public health activities of prevention and surveillance, and decision-making process, ushering a new era of public health.

Public opinion on vaccines: the role of the scientific community in Italy

Background

After rising for years, vaccination rates in Italy fell until 2015 because of unfounded safety concerns, abetted by some government and court actions. Public education and a 2017 law on mandatory vaccination have boosted rates since then. So far only a few papers have examined the correlation between beliefs and attitudes towards vaccines and the level of trust in the scientific community regarding vaccinations in the general population.

Methods

Data were extracted from the Italian section of the last two editions of the European Social Survey (ESS), the first carried out between September and November 2017, the latter between December 2018 and March 2019. A descriptive analysis was conducted using survey data. In the two editions respectively 2,626 and 2,745 persons were interviewed. The main outcomes assessed was comparing the two surveys, so as to highlight the key changes in public opinion on vaccines.

Results

In the 2017 edition, 19% of the respondents believed in the harmfulness of vaccines, out of them 29% did not even have trust in the scientific community while those confident in the safety of vaccines were 50%. In the 2019 survey, the proportion of those who believed vaccines to be harmful fell to 15%, the undecided rose to 15%, those opposed to the idea that vaccines are harmful became 63%, not responding people were 8%. Correspondingly, trust in the scientific community about vaccines has increased from 57% in the first survey to 70% in the last one.

Conclusions

The scientific community and research bodies in the last years, in support of the Ministry of Health, have made a huge effort in the public debate on vaccines. This might play a role in increasing the public confidence in the safety of vaccines and the adherence to vaccination campaigns, changing the climate with regard to vaccination in general.

Key messages

Italians changed their opinions on vaccines between two ESS surveys. The scientific community had a relevant role in the public debate on vaccines.

Understanding the determinants of vaccine hesitancy among adolescents: a systematic review

Background

The WHO defines vaccine hesitancy (VH) as ‘a delay in acceptance or refusal of vaccines despite the availability of vaccine services'. In spite of the models explaining VH and the tools used to address it, VH still represents a current problem and has been declared one of the top ten global health threats by WHO in 2019. This is mainly true for the adolescents who represents 25% of the global population. This systematic review aims to address the determinants of VH in this target population.

Methods

PubMed, Web of Science and Scopus were searched to retrieve articles, published in English, assessing adolescents' attitudes and confidence towards vaccinations with any study design (qualitative or quantitative) from the inception until Dec 2020. A methodological quality assessment of the articles was performed based on the study designs.

Results

Out of 14,704 articles, 20 studies were included in the qualitative analysis. Ten out of 20 studies were evaluated as of “good quality”, while nine had “moderate quality” and only one had “poor quality”. Factors associated to a positive attitude towards vaccination included knowledge of vaccine preventable diseases, the awareness of vaccines, their efficacy, safety and free of charge, higher education level and active involvement in decision-making. An association between VH and socio-economic conditions was also highlighted.

Conclusions

This systematic review elucidated a better understanding of the determinants of VH among the adolescent population. Adolescence represents a crucial phase of life in which boys and girls begin to make significant choices about their health and develop attitudes and behaviours that continue into adulthood. Indeed, their concerns and needs in respect to vaccination should be widely examined and taken into consideration to plan tailored interventions to promote vaccination and reduce VH.

Key messages

Vaccine hesitancy among adolescents is a major global health priority. This problem is little studied and further studies and initiatives aimed at increasing awareness of the problem should be deserved.

Covid-19 vaccination in a teaching hospital in Rome: preliminary results from a retrospective study

 

Healthcare workers (HCWs) are on the frontline fight against the ongoing pandemic with an increased risk of infection from COVID-19. As of December 27, 2020, approximately 89,879 COVID-19 cases had been reported among HCWs in Italy. Vaccination plans recommend that initial supplies of COVID-19 vaccine be allocated to HCWs because their early protection is crucial to preserve capacity to care for patients. The aim of this study is threefold: to investigate the factors influencing the likelihood towards vaccination, to estimate the vaccine efficacy (VE) in a hospital setting and to assess the frequency of adverse reactions (AR). This retrospective study was conducted in an Italian teaching hospital from December 28, 2020 to March 31, 2021 (before the introduction of mandatory vaccination for HCWs). A total of 6,649 individuals was included. HCWs were divided into physicians, nurses and other HCWs. Univariate analyses and a multivariate logistic regression were run with an alpha of 0.05. VE was estimated as the proportionate reduction in disease attack rate between the unvaccinated and vaccinated. Out of 6,649 HCWs, 5,162 were fully vaccinated against COVID-19. Among the selected job categories, 82% of physicians, 79% of nurses and 68% of other HCWs were vaccinated. The findings of the logistic regression depicted that the 41-60 years old age class, compared with the youngest age class, was statistically significant (OR 1.17, 95% CI 1.03-1.33) in influencing vaccination, as well as being nurses (OR 0.80, 95% CI 0.69-0.92) or other HCWs (OR 0.45, 95% CI 0.39-0.52) in comparison with physicians. VE equaled 92.83% (p &lt; 0.05). The frequency of serious and not serious AR was 0.03% and 2.9%, respectively. Sustaining and boosting COVID-19 vaccination campaigns is effective for preventing SARS-CoV-2 infection in real-world conditions. COVID-19 vaccination among HCWs is a critical public health measure to safeguard HCWs themselves, patients and the hospital community.

Key messages

In light of the encouraging efficacy and safety of COVID-19 vaccination, it represents an essential strategy to protect HCWs themselves, their patients and the hospital community. Despite the introduction of mandatory vaccination, policy-makers should set up tailored strategies of clear communication to reduce reluctancy to vaccination among HCWs.

Algorithms and Artificial Intelligence in Primary Care for conscious drug use: a systematic review

 

Primary care is a growing medical field willing to become a more integrated and technological asset. Although big changes already happened and more investments have been made, a limited amount of literature describes processes and technologies there applied or to be used. This paper aims to evaluate the efficacy and usability of different types of algorithms in primary care to improve drug safety by speeding up processes and achieving greater accuracy opening the path to providing better healthcare overall. The PICO model was adopted, three electronic databases (PubMed, Cochrane, Web of Science) were searched using appropriate keywords. Selected studies were assessed for quality and risk of bias using the National Institutes of Health Quality Assessment of Controlled Intervention Studies. Data were analysed using descriptive statistic, comparison of drug usage between algorithms or artificial intelligence application and usual care was performed using a χ2 test(α = 0.05). Out of 2207,19 studies were included,37% of them regarding error prevention,21% drug interactions,21% drug monitoring,16% drug prescription,5% drug administration. Results showed an easier and safer medication use in 74% of studies, a loss of safeness and accuracy in 16%; 10% of total studies did not come up with a valid esteem of results either for inadequate availability of the AI machine or because of the heterogeneity of the results in different settings. The evaluation of errors prevention, 40% of total studies, showed the most statistically significant results with 88% of positive outcomes from AI application. The results support that this technological approach to drugs management could contribute to the safety of treatment and to increase patients' and general practitioners' satisfaction. The application of AI or algorithms is significantly associated with a reduction of drug use errors (p &lt; 0.05). Future studies should work toward establishing a gold standard to measure AI performances.

Key messages

Artificial Intelligence and Algorithms in primary care have the potentiality to disrupt patient care with a safer and faster medication management. A comparison between Artificial Intelligence or algorithms and standard clinical practice may help finding the medication fields where a technological support could lead to better results.

Educational Interventions for Promoting Food Literacy and Patient Engagement in Preventing Complications of Type 2 Diabetes: A Systematic Review

The present review aims to map the current literature on educational interventions to promote food literacy in type 2 diabetes, with a particular focus on the concept of patient engagement. The systematic review was implemented on five databases with no restrictions on the publication year. The studies selected for the review were focused on patients with type 2 diabetes, ranging from 2003 to 2021 and published in 13 countries (44% USA). Thirty-three articles were analyzed. Twenty-seven articles targeted singular patients; fifteen articles conceptualized patient engagement as self-management. In seven articles, the provider is a multidisciplinary team. Twenty articles did not report a theoretical framework in the intervention development, and eleven did not use an intervention material. Twenty-six articles did not use a technology proxy. Outcome categories were narratively mapped into four areas: clinical, psychological, behavioral, and literacy. To date, most of the interventions are heterogeneous in the adopted methodology, measures, and outcomes considered. More attention should be given to the psychosocial characterization of patient engagement as well as the technological support. High-quality, randomized controlled trials and longitudinal studies are lacking and need to be conducted to verify the efficacy of these insights.

Moving forward: Cost-Effectiveness of PrEP in HIV prevention for Men Who Have Sex with Men in Italy

Globally, in 2018 1.7 million people contracted Human Immunodeficiency Virus (HIV) and 770,000 people died from AIDS-related illnesses. Men Who Have Sex with Men (MSM) have one of the highest probabilities of HIV transmission.

In Italy, in 2018 2,847 new HIV cases were diagnosed, of which 39% among MSM. The MSM population accounts for 16,690 individuals whereof 50% already underwent the Highly Active Antiretroviral Therapy (HAART). The aim of this study is to evaluate the cost-effectiveness of daily Pre-Exposure Prophylaxis (PrEP) in the Italian MSM susceptible population.

A Markov transition model was calibrated to the HIV epidemic among MSM in Italy, comparing PrEP to naïve patients (NP). Model parameters were retrieved by querying scientific databases. Transition probabilities were adjusted for incidence of HIV while costs and benefits were discounted at an annual rate of 3%. The impact on results of critical parameters was explored through a Monte Carlo-based sensitivity analysis. The cost-effectiveness analysis results were reported as Incremental Cost-Effectiveness Ratio (ICER) express as € per Quality Adjusted Life Year (QALY) gained.

The introduction of such a PrEP program would result in a total cost of €822,398,199 million and lead to a gain of 70,762 discounted QALYs over an 85-year time horizon.

Assuming a 92% efficacy of PrEP therapy, the ICER for the PrEP program is €4,346.16/QALY gained. This value is definitively lower than acceptability NICE threshold (£20,000).

PrEP can reduce the infection rate up to 60% in a five-year period. The Monte Carlo simulation confirmed the robustness of the model results.

This analysis showed PrEP to be cost-effective when used in a susceptible population. Even if PrEP doesn't protect from other sex-related infectious diseases, it could prevent HIV transmission, thus breaking down HIV-infection incidence rate. Each country should reflect on the real possibility to implement a robust Public Health program pondering the adoption of PrEP.

Key messages

PrEP is very effective at reducing HIV infection when taken correctly. It is the backbone in the “combination prevention”, necessary to reach the SDG of ending the AIDS epidemic by 2030. This preliminary analysis suggests that the introduction of a daily PrEP program for MSM in Italy is cost-effective and possibly cost saving in the long term.

Urban Health as a Complex System

The 17 Sustainable Development Goals (SDGs) are a complex system comprising 169 targets and about 230 indicators. Urban Health could be considered a complex system since it deals with 15 out of 17 SDGs, excluding the two related to life below water and life on land. According to the World Health Organization, to achieve the SDGs, countries have committed to organize Urban Health initiatives to improve the social, economic, and physical environments promoting health and sustainability globally. Cities will become more inclusive, safer and more sustainable, which are important driving forces to implement the development equation. To set up a framework to point out that Urban Health is a complex system oriented to the achievement of the SDGs. It has been conducted an extensive literature review on databases (PubMed, Embase, Web of Science and Scopus) using keywords in 3 strings combined with Boolean operators: SDGs and Urban Health, Urban Health as Complex System and Urban Health, Environmental Health and Public Health as Complex Systems. In addition, a grey literature review has been carried out. Out of 1005 publications, 21 were eventually included: 14 publications relate to the interdependent relationships between SDGs and Urban Health, with regard to the association between Urban Health and complex system, 3 publication studied the effects and implications of such correlation, 4 focused on Environmental Health and Public Health in relation with the complex system. The selected publications suggested methodologies aimed at setting up an urban health framework to achieve SDGs. There is an initial orientation focused on the study of Urban Health problems aimed at achieving SDGs from the perspective of complex systems. We highlight the need to conduct further studies on a more detailed framework in order to address this type of approach.

Community Engagement: Reducing inequalities acting on environmental health. A Systematic Review

Sustainability is one of the most important challenges for Healthcare Systems all over the world. According to the Sustainable Development Agenda, one of the goals is to reduce inequalities, and environmental health is faced by several specific goals. Community Engagement can both empower vulnerable populations (so reducing inequalities) and identify the prior environmental issues to address. The aim was to search for public health programs using Community Engagement tools in healthy environment building.

A systematic review was conducted searching on Scopus, MEDLINE and Cochrane databases. The search string was created according to the Population-Intervention-Context-Outcome model. The Risk Of Bias In Non-randomized Studies-of Interventions tool was used to assess quality. Data analysis was based on descriptive statistics and a Chi-Square test was performed to compare studies in which the community carried out engagement interventions with or without the direction of public health institutions (p &lt; 0.05).

Of 182 articles, 11 were eventually included. Risk of Bias was moderate in 70% of the articles.

7 studies were conducted in rural areas, while 4 in urban contexts. Target populations were children in 20%, adults in 50% and elderly in 30% of the articles. Concerning the intervention design, 9 studies included the research of local leaderships, and in 7 there were both context study (to identify the main barriers and facilitators) and the active planning of motivational meetings by public health professionals. We found that the level of engagement reached is highly correlated with the presence of public health professionals acting as engaging coaches (p = 0.007).

Community engagement allows Public Health to carry out promotion and prevention programs by leveraging community forces. This study shows that one of the most important ingredients to make it work is the active presence of the Public Health professionals acting as community coaches.

Factor VII Activity Is an Independent Predictor of Cardiovascular Mortality in Elderly Women of a Sicilian Population: Results of an 11-year Follow-up

The aim of the Epidemiological project “Ventimiglia di Sicilia” is to identify the cardiovascular risk factors in a Sicilian population with a low risk profile and healthy nutritional habits. The risk of cardiovascular mortality in older subjects (over 60 years of age) is presented for an 11 year follow-up. Females showed higher prevalence of diabetes mellitus, hypertension, obesity and higher levels of total, LDL and HDL cholesterol, factor VII activity and fibrinogen compared to males. Cardiovascular mortality was related to hypertension and obesity in males, to high factor VII activity, obesity and diabetes mellitus in females. In a Logistic Regression model the same variables were independently correlated to cardiovascular mortality with the exception of obesity. In conclusion, these findings suggest that in a population with a low risk profile, other factors, such as factor VII activity, may emerge as predictors of cardiovascular mortality.

Current practice of chronic hepatitis B treatment in Southern Italy

BACKGROUND

Treatment choice for chronic HBV infection is a continuously evolving issue, with a wide range of options. We aimed to evaluate the current practice of HBV therapies in the real world in Southern Italy.

METHODS

A prospective study enrolling over a six month period (February-July 2010) all consecutive HBsAg positive subjects, never previously treated, referred to 16 liver units in two Southern Italy regions (Calabria and Sicily).

RESULTS

Out of 247 subjects evaluated, 116 (46.9%) had HBV-DNA undetectable or lower than 2000 UI/ml. There were 108 (43.7%) inactive carriers, 103 (41.7%) chronic hepatitis, and 36 (14.6%) liver cirrhosis. Antiviral treatment was planned in 94 (38.0%) patients (26 cases with Interferon or Pegylated Interferon and 68 with nucleos(t)ides analogues). As many as 49.5% of subjects with chronic hepatitis did not receive antiviral treatment.

DISCUSSION

The majority of chronic HBsAg carrier referring centres for evaluation were not considered suitable for antiviral treatment. Nucleos(t)ides analogues are the preferred first choice for therapy. A long-lasting period of observation may be needed to make appropriate therapeutic decisions in several cases.

Current practice of chronic hepatitis B treatment in Southern Italy

BACKGROUND

Treatment choice for chronic HBV infection is a continuously evolving issue, with a wide range of options. We aimed to evaluate the current practice of HBV therapies in the real world in Southern Italy.

METHODS

A prospective study enrolling over a six month period (February-July 2010) all consecutive HBsAg positive subjects, never previously treated, referred to 16 liver units in two Southern Italy regions (Calabria and Sicily).

RESULTS

Out of 247 subjects evaluated, 116 (46.9%) had HBV-DNA undetectable or lower than 2000 UI/ml. There were 108 (43.7%) inactive carriers, 103 (41.7%) chronic hepatitis, and 36 (14.6%) liver cirrhosis. Antiviral treatment was planned in 94 (38.0%) patients (26 cases with Interferon or Pegylated Interferon and 68 with nucleos(t)ides analogues). As many as 49.5% of subjects with chronic hepatitis did not receive antiviral treatment.

DISCUSSION

The majority of chronic HBsAg carrier referring centres for evaluation were not considered suitable for antiviral treatment. Nucleos(t)ides analogues are the preferred first choice for therapy. A long-lasting period of observation may be needed to make appropriate therapeutic decisions in several cases.

Hypertension and diabetes mellitus are associated with cardiovascular events in the elderly without cardiovascular disease. Results of a 15-year follow-up in a Mediterranean population

BACKGROUND AND AIMS

Epidemiological prospective data on cardiovascular (CV) events in elderly subjects from Mediterranean populations are lacking. We aimed to investigate 15-year incidence of CV events and to evaluate the association with CV risk factors in an elderly Mediterranean population.

METHODS AND RESULTS

The population of a small Sicilian village were enrolled, visited and a blood sample was drawn at baseline. CV events were recorded in the 15 years of follow-up. From 1351 subjects (75% of the resident population); 315 were in the age range 65-85 years; 266 subjects free from CV disease were analysed. Seventy-seven CV events were recorded in 73 out of 266 subjects, with a 19.7% rate (in 10 years). Hypertension (HTN) (hazards ratio=2.1) and diabetes mellitus (DM) (hazards ratio=1.8) were independently associated with CV events. Subjects with both DM and HTN showed a lower survival free of CV events compared to those with DM or HTN.

CONCLUSIONS

In a 15-year follow-up of an elderly Mediterranean population free from CV disease, diabetes mellitus and hypertension were related to CV events. The control of risk factors in the elderly needs to be reinforced to achieve better results in terms of CV prevention.

Description of a rare case of splenic abscess due to spontaneous E. cohi bacteremia in a cirrhotic patient

We report on a rare case of splenic abscess due to spontaneous Escherichia coli bacteremia in a 49-year old cirrhotic. No other source potentially responsible for bacteremia was found through careful diagnostic research. Splenic abscess appeared from ultrasonography and computerized tomography as a 6-7 cm lesion located at the lower splenic pole. Blood cultures allowed to isolate E. coli which, on the basis of antibiotic susceptibility, was treated by a 21-day intravenous cetazidime course at a dose of 6 g/day. The isolated E. coli strain resulted as quinolone-resistant. Disappearance either of high fever or of abscessual splenic lesion was achieved without surgery after the antibiotic round. Spontaneous bacteremia may occur in cirrhotic patients due to intestinal bacteria traslocation from gut lumen to blood. Nevertheless, isolated splenic localization is a very rare event.

Protective effect of carnosine during nitrosative stress in astroglial cell cultures

Formation of nitric oxide by astrocytes has been suggested to contribute, via impairment of mitochondrial function, to the neurodegenerative process. Mitochondria under oxidative stress are thought to play a key role in various neurodegenerative disorders; therefore protection by antioxidants against oxidative stress to mitochondria may prove to be beneficial in delaying the onset or progression of these diseases. Carnosine has been recently proposed to act as antioxidant in vivo. In the present study, we demonstrate its neuroprotective effect in astrocytes exposed to LPS- and INFgamma-induced nitrosative stress. Carnosine protected against nitric oxide-induced impairment of mitochondrial function. This effect was associated with decreased formation of oxidatively modified proteins and with decreased up-regulation oxidative stress-responsive genes, such as Hsp32, Hsp70 and mt-SOD. Our results sustain the possibility that carnosine might have anti-ageing effects to brain cells under pathophysiological conditions leading to degenerative damage, such as aging and neurodegenerative disorders.

[Chronic HPV correlated lymphedema of external genitals: a case report]

The Authors describe an unusual case of association between skin lymphangiomas and HPV infection in external genitals. The encountered difficulties in diagnosis represented an excellent example of efficient integration among specialists of different medical branches

[Recurrent cystopyelitis related to inguinal bladder hernia: a case report evaluated by color Doppler US]

The authors describe an unusual inguinal biadder case responsible for recurrent urinary tract infections. The Eco Color Doppler technique allowed correct diagnosis of the pathology, whose first signs (recurrent cystopyelitis) could have been erroneously correlated to the diabetic status of the patient Subsequently, the authors stress the importance of this technique as a useful tool to ensure swift and correct diagnosis.

Factor VII activity is an independent predictor of cardiovascular mortality in elderly women of a Sicilian population: results of an 11-year follow-up

The aim of the Epidemiological project "Ventimiglia di Sicilia" is to identify the cardiovascular risk factors in a Sicilian population with a low risk profile and healthy nutritional habits. The risk of cardiovascular mortality in older subjects (over 60 years of age) is presented for an 11 year follow-up. Females showed higher prevalence of diabetes mellitus, hypertension, obesity and higher levels of total, LDL and HDL cholesterol, factor VII activity and fibrinogen compared to males. Cardiovascular mortality was related to hypertension and obesity in males, to high factor VII activity, obesity and diabetes mellitus in females. In a Logistic Regression model the same variables were independently correlated to cardiovascular mortality with the exception of obesity. In conclusion, these findings suggest that in a population with a low risk profile, other factors, such as factor VII activity, may emerge as predictors of cardiovascular mortality.

Prevalence of overweight and obesity in a rural southern Italy population and relationships with total and cardiovascular mortality: the Ventimiglia di Sicilia project

OBJECTIVE

We investigated the prevalence of overweight and obesity and their relationships with the main cardiovascular risk factors in the population of Ventimiglia di Sicilia, a rural village in Southern Italy characterized by low cholesterol levels and by a low incidence of early coronary heart disease mortality. We related all deaths to body weight and fat distribution during an 8 y follow-up.

DESIGN

Cross-sectional and prospective observational study.

SUBJECTS

A total of 835 free-living individuals, 363 males and 472 females, of age between 20 and 69 y.

MEASUREMENTS

In all participants body weight, waist-to-hip ratio (WHR), cardiovascular risk factors and plasma lipids were measured. During the follow-up, total and cardiovascular deaths were registered.

RESULTS

We found a high overall prevalence of subjects with overweight or obesity (respectively 45.0% and 27.7%), with great differences among classes of age. As expected, body weight and fat distribution were associated with diabetes, hypertension, dyslipidemia and with a worsening of lipid profile. During the follow-up we registered 37 total and 11 cardiovascular deaths. All-cause and cardiovascular mortality risks were, respectively, 1.64 (95% CI 0.65-4.15) and 2.71 (95% CI 0.29-25.26) in subjects with a body mass index (BMI) of 27-29.99 kg/m2 and 2.45 (95% CI 1.03-5.87) and 5.36 (95% CI 1.41-62.01) in subjects with a BMI of > or =30 kg/m2 in comparison with participants with a BMI of <27 kg/m2, and 3.48 (95% CI 1.46-8.30) and 4.55 (95% CI 1.12-18.40) in subjects with a WHR higher than the median in comparison with individuals with a WHR lower than the median.

CONCLUSION

The Ventimiglia di Sicilia Study highlights the great importance of overweight and obesity as a public health issue in a rural population and indicates that it is necessary to consider the impact of body weight and fat distribution on both total and CHD mortality.

Prevalence of biliary lithiasis in the elderly people of a small town in Sicily

The aim of the present study was to determine the prevalence of biliary lithiasis (BL) and its major associated factors in the elderly people of a small town in Sicily. All inhabitants over the age of 65 were interviewed and underwent a general physical examination, blood tests and ultrasonography of the gallbladder and biliary tracts. The final group included 328 subjects (162 men and 166 women), representing 63.1% of the population asked to participate, with a mean age of 74.3 +/- 6.8 years (range 65-95). The prevalence of BL (lithiasis in progress + subjects cholecystectomized for previous calculosis) was 18.6%. No male subject had been cholecystectomized. Prevalence was higher in women than in men, but there was no progressive increase with age. There was no significant correlation between number of pregnancies and BL and there was no statistically significant difference between subjects with and without lithiasis for total cholesterol, triglycerides, HDL-cholesterol, A-I and B apoprotein values; a significant difference was found only for body weight values (p less than 0.01). Stones were more often multiple and more radiopaque than in younger subjects; specific symptoms and positive family histories were found in 22% and 18% of the study group, respectively.
