SUMMARYEncephalitis generally results in a serious illness requiring hospitalization. The aim of this study was to describe the epidemiology of hospitalization for encephalitis in Italy, taking into account the geographical distribution, aetiology, seasonality and evolution of hospitalization rates over recent years. The mean hospitalization rate was 5·88/100 000. For most of these hospitalizations (n=13 119, 55·6%), no specific cause of encephalitis was reported. The most common aetiological category was 'viral', which accounted for 40·1% (n=4205) of such hospitalizations (rate 1·05/100 000). Within this category, herpes virus was the leading causative agent (n=1579, 0·39/100 000). This report highlights a significant increase of 'viral encephalitis not otherwise specified' (ICD-9 code 049·9) vs. a reduction of all other causes. A seasonal pattern was noted in people aged 65 years in this group. Specific surveillance of encephalitis without known origin should be reinforced in order to identify the potential role of emerging pathogens and to design preventive interventions.

Background/Objectives: Cytomegalovirus (CMV) is widespread and mostly causes asymptomatic infections in immunocompetent hosts, but it may lead to severe and life-threatening diseases in immunocompromised individuals, such as transplant patients and congenitally infected children, representing a significant public health concern. Although there are no licensed CMV vaccines, the development of a CMV vaccine is considered a high priority due to its potential to reduce the burden associated with CMV-related complications, and several approaches are under investigation. The objective of this systematic review was to synthesize the evidence on various CMV vaccines currently under clinical development. Methods : According to the PRISMA guidelines (PROSPERO ID: CRD42024516601), a comprehensive literature search was conducted to identify all the randomized controlled trials that have evaluated the safety, immunogenicity, and efficacy of vaccine candidates compared to a placebo. A total of 26 studies were identified: 11 on transplant patients and 15 on healthy individuals. Results : Several vaccine candidates have shown encouraging results in terms of safety and specific immune responses, notably adjuvanted gB vaccines and DNA vaccines targeting gB and pp65. The results were divided into RCTs on healthy individuals and those on transplant recipients, because the CMV-specific immune response to a vaccine is complex and varies depending not only on the type of vaccine, but also on the immunological status of the individual. Conclusions : Challenges remain in achieving broad efficacy across diverse populations, particularly for immunocompromised patients. Thus, the present work seeks to support future decisions and guide further research in the development of an effective and widely available CMV vaccine.

Background and Aim: Fibrosis-4 (FIB-4) index is a widely used test for non-invasively assessing liver fibrosis. We aimed to investigate the association between FIB-4 index and risk of all-cause mortality in patients at high cardiovascular (CV) risk and to determine whether coexisting renal dysfunction mediates this association., Methods and Results: Single-center prospective study of 994 patients with established or suspected coronary artery disease undergoing coronary angiography, followed for a median of 44 months. Mortality data were obtained through the Italian Health Card Database. At baseline, the median FIB-4 index was greater in deceased vs. alive patients (1.71 vs. 1.38, p < 0.001) and in those with reduced eGFR than in those with normal eGFR (1.65 vs. 1.37, p < 0.001). For each unit increase in the baseline log-FIB-4 index, the risk of all-cause mortality sharply increased during the follow-up (hazard ratio [HR] 2.31, 95%CI 1.31-4.08, p = 0.004). Similarly, assuming the lowest baseline FIB-4 risk category as the reference, the risk of all-cause mortality progressively increased across the indeterminate (HR 1.82, 95%CI 1.18-2.82, p = 0.007) and the highest baseline FIB-4 risk categories (HR 2.33, 95%CI 1.37-3.97; p = 0.002). A causal mediation analysis showed that about one-third of the effect of FIB-4 index on mortality risk was mediated by reduced eGFR (32.8 %, p = 0.01)., Conclusions: Increased FIB-4 index predicts the long-term risk of all-cause mortality in patients at high CV risk, and this risk is, at least in part, mediated by reduced eGFR. Further prospective studies are needed to confirm these findings., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2024 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Prostate cancer (PCa) is a common cancer among men, and it has a multifactorial etiology. Cadmium (Cd), a toxic heavy metal classified as a carcinogen by the IARC, can cause various acute and chronic effects. This systematic review and meta-analysis aims to update previous findings on the association between Cd exposure and PCa. We carried out a literature search in PubMed, Web of Science, and Scopus up to May 2024, identifying eight new articles. The effect size from the highest and lowest exposure categories were extracted and analyzed using a random-effects model. Heterogeneity was assessed with the I 2 test, and publication bias was evaluated using funnel plot asymmetry. Overall, the effect size for PCa associated with Cd exposure, combining previous and new articles, was 1.11 (95% CI 0.85-1.45). Heterogeneity was high, but no significant publication bias was detected. For studies from Europe, the effect size was 1.47 (95% CI 1.00-2.17). Notably, 11 articles from the previous systematic review and meta-analysis highlighted that higher Cd exposure is significantly associated with more aggressive histopathological types of PCa (OR 1.50, 95% CI 1.08-2.07). These findings suggest a potential public health concern, indicating the need for further research to clarify the risk associated with Cd exposure.

Coronary artery disease (CAD), particularly three-vessel coronary disease (3VD), is the main cause of death in industrialized countries. Chronic kidney disease is an independent risk factor for CAD. The CHA 2 DS 2 -VASc score shows a good ability to predict CV events in high-risk population independently from atrial fibrillation. The aim of the present study was to evaluate the association between the R 2 CHA 2 DS 2 -VASc score and 3VD in a population of patients at high cardiovascular risk. Monocentric prospective study evaluated 1017 patients undergoing coronary angiography. The R 2 CHA 2 DS 2 -VASc score was obtained by adding 2 points to the CHA 2 DS 2 -VASc score in case of eGFR < 60 ml/min/1.73m 2 . Coronary lesions causing ≥ 50% reduction of a major epicardial vessel diameter were considered significant. Patients were grouped based on R 2 CHA 2 DS 2 -VASc tertiles and according to the severity of CAD: 3VD vs No-3VD. The 3VD group showed significantly higher R 2 CHA 2 DS 2 -VASc score than the No-3VD group (4.20 ± 2.18 vs 3.36 ± 2.06, p < 0.001). The risk of 3VD increased by 21% for every 1-point increase in the score (OR 1.21; 95% CI 1.13-1.28, p < 0.001). The prevalence of 3VD was higher among patients belonging to higher tertiles of R 2 CHA 2 DS 2 -VASc (17.2% vs 26.7% vs 33.6% for first, second, and third tertile respectively, p < 0.001) with a risk more than doubled for the third tertile compared to the first one (OR 2.45; 95% CI 1.71-3.49, p < 0.001). The R 2 CHA 2 DS 2 -VASc score is independently associated with 3VD in patients at high cardiovascular risk. The score could be considered a useful tool for clinicians to identify patients who are at high risk of 3VD., (© 2024.

Plastic pollution is a growing concern. It can form smaller particles called microplastics (<5 mm). Microplastics can break down into even smaller pieces called nanoplastics (<1 μm). These minute particles can infiltrate human cells and tissues, with their health impacts still largely undetermined. On average, a liter of bottled water includes about 240,000 tiny pieces of plastic. The purpose of this study was to evaluate the association between the use of bottled plastic water (BW) and several health outcomes. Utilizing data from the Italian National Institute of Statistics' "Aspects of Daily Life" survey (N = 45,597), we employed logistic regression to explore the correlation between BW consumption and the prevalence of various chronic diseases, including hypertension, gastric/duodenal ulcers, and kidney stones. Adjustments were made for covariates such as education, age, gender, and economic resources. Our analysis indicated a statistically significant association between BW consumption and increased risk of hypertension (Odds ratio [OR] = 1.05, 95% confidence interval [CI] 1.00-1.11), diabetes (OR = 1.09, 95% CI 1.01-1.18), gastric/duodenal ulcers (OR = 1.21, 95% CI 1.07-1.38), and kidney stones (OR = 1.17, 95% CI 1.03-1.32). The consumption of BW is associated with heightened risk for certain health conditions. Policymakers and healthcare providers should consider implementing targeted prevention strategies and awareness campaigns.

Objective: Psychological stress can be a common risk factor for the development of oral and systemic disease; therefore, analysis of a pathophysiologic mechanisms that may explain this association may be significant in planning preventive strategies. The aim of this study was to investigate the association amongst academic stress, periodontal health, and salivary cortisol and nitrite and nitrate levels in a sample of university students., Methods: Participants (N = 14) were classified into 2 groups according to their exposure to academic stress due to periods of university exams (n = 6 and n = 8, respectively). All participants were subjected evlauted for their behavioural, psychological, and anthropometric parameters, as well as an oral health examination. A real-time polymerase chain reaction analysis in samples of saliva and plaque was used to detect Prevotella intermedia and Veillonella dispar as well as the total bacterial count. Nitrite/nitrate ratio (NR ratio) and cortisol in saliva were evaluated by enzyme-linked immunosorbent assay., Results: Full Mouth Bleeding Score, Full Mouth Plaque Score, and Gingival Index were significantly higher in the group exposed to academic stress. Nitrite was directly related to the presence of V dispar (coefficient, 0.13; P = .00; CI, 0.07 to 0.19) and inversely related to total bacterial count (coefficient, -0.07; P = .012; CI, -0.13 to 0.02). NR ratio was directly related to V dispar (coefficient, 4.35; P = .010; 95% CI, 1.35 to 7.36) and inversely related to total bacterial count (coefficient, -4.05; P = .018; 95% CI, -7.32 to 0.86)., Conclusions: These results confirm the importance of stress on periodontal health and salivary nitrite concentration and highlight a potential differential role of specific bacteria on nitrite concentration in saliva., Competing Interests: Conflict of interest None disclosed., (Copyright © 2024 The Authors.

Hip fracture is a common condition in older adults, leading to disability and mortality. Several studies have demonstrated the association between nutritional status and the risk of a negative health outcome after fractures. In this systematic review, we evaluated the association between malnutrition and mortality, changes in mobility/living arrangements, and postoperative complications, such as delirium, in older patients with hip fractures. A literature search on the PubMed, Web of Science, and Scopus databases, up to September 2023, was conducted to identify all studies involving older subjects that reported an association between MNA/GNRI/PNI/CONUT and health outcome after hip fracture. Meta-analysis was performed by a random-effects model using risk values (RR, OR, and HR) extracted from the 14 eligible selected studies. Malnutrition significantly increased the risk of any analyzed adverse outcome by 70% at 1 month, and up to 250% at 1 year. Malnutrition significantly increased delirium risk by 275% (OR = 2.75; 95% CI 1.80-4.18; p ≤ 0.05), mortality risk by 342% (OR = 3.42; 95% CI 2.14-5.48; p ≤ 0.05), mortality hazard risk by 351% (HR = 3.51; 95% CI 1.63-7.55; p ≤ 0.05) at 1 month, and transfer-to-more-supported-living-arrangements risk by 218% (OR = 2.18; 95% CI 1.58-3.01; p ≤ 0.05), and declined mobility risk by 41% (OR = 1.41; 95% CI 1.14-1.75; p ≤ 0.05), mortality risk by 368% (OR = 3.68; 95% CI 3.00-4.52; p ≤ 0.05), and mortality hazard risk by 234% (HR = 2.34; 95% CI 1.91-2.87; p ≤ 0.05) at 1 year. Malnutrition of older patients increases the risk of death and worsens mobility and independence after hip fractures. The results of the present study highlight the importance of nutritional status evaluation of older subjects with hip fractures in order to prevent potential adverse outcomes (Registration No: CRD42023468751).

Safe water is a global public health concern amid increasing scarcity and pollution. Bottled water production and consumption contribute to these problems. This study examines tap water consumption in Italy, assessing associated sociodemographic factors and related health outcomes such as obesity and self-perceived health status. Data from the Italian National Statistics Institute's "Aspects of daily life" survey (N = 45,597) were analyzed. Covariates included education, age, gender, economic status, region, concerns about waste and climate change, consumption of carbonated drinks excluding water, alcohol consumption, consumption of vegetables, consumption of snacks, body mass index, and self-perceived health status. Bivariate analyses and mixed-effect logistic regression models explored the associations. People who drink tap water made up 19,674, with a higher prevalence in people aged 45 to 59 old, people with a graduate/post-graduate degree diploma, with optimal economic resources, people concerned about waste production and climate change, and those coming from the north-east regions of Italy. Underweight people showed a higher prevalence of TW consumption as well as those who less than occasionally drank carbonated drinks, drank alcohol, consumed vegetables more than once a day and snacks less than once a week, dairy products more than once a day, sweet less than once a week, cured meat less than once a week, and chicken meat less than once a week, those with no consumption of sheep meat, consumption of beef meat less than once a week and consumption of pork meat less than once a week, and those with a satisfactory level of perceived health status. Regressions showed that all other age classes are less likely to drink tap water than people younger than 20 years old. The category with "inadequate" economic resources is more likely to consume tap water. Low educational classes show a low likelihood of consuming tap water as well as islands. A concern about waste production and climate change is associated with an increased likelihood of consuming tap water. Tap water consumption was negatively associated with obesity but not with a satisfactory self-perceived health status. Insights from this study can inform public health strategies.

Background: Several socioeconomic conditions may influence subjects' adherence to healthy eating habits. Food consumption may be influenced by external stress during crisis periods; however, the effects of these events on food habits are difficult to predict. Also, a pandemic crisis like the recent COVID-19 pandemic may have influenced dietary habits and food consumption. The objective of this study was to compare the dietary habits of Italian people before the COVID-19 pandemic with those belonging to the year 2020 in a nationwide population sample., Materials and Methods: Information on dietary habits has been obtained from the multi-purpose survey on families' "Aspects of daily life", carried out in Italy by the Italian National Statistics Institute (ISTAT). We analyzed data coming from 2016 and 2020 editions of the survey (43,000 subjects each year). We used population attributable fraction (PAF) adjusted for age, defined as the proportional reduction in unhealthy diet that would occur if all participants had had a higher education, assuming higher educated individuals as more socially advantaged. Prevalence association for each dietary exposition has been calculated through logistic regression., Results: Looking at aggregated data from 2016 and 2020 both men and women showed a high prevalence of unhealthy dietary habits. Regarding men, excessive consumption of eggs, pork meat, and bovine meat was characterized by a PAF attributable to socioeconomic conditions to an extent greater than 30%. Women showed the same trend. Focusing on different years of investigation, in 2020, during the COVID-19 pandemic, men and women increased their consumption of eggs, cooked fats, snacks, and sweets, and reduced consumption of fruits and vegetables. Additionally, women increased the assumption of dietary products and meat. Both sexes registered an increase in overweight and obese subjects in 2020., Conclusions: To our knowledge, this study was the first in our country to use a yearly, nationwide sample to analyze dietary habits by examining specific types of various foods on a nationwide scale and establishing a correlation between these habits and the COVID-19 pandemic. Our results showed unbalanced dietary habits of the Italian population with an excess of consumption of several foods like eggs, cooked fats snacks, and sweets with low consumption of fruits and vegetables. Socioeconomic differences influence food choices but in a complex way since they seemed to affect some wrong dietary habits but not others, especially regarding fruits and vegetables assumption where differences were less evident among social classes. Outside stressors like a crisis period such as the COVID-19 pandemic seem to have an important role in both men and women regarding the assumption of so-called "junk food"., (© 2024. The Author(s).)
