The trim-and-fill method for publication bias: practical guidelines and recommendations based on a large database of meta-analyses

In the past few years, there has been increasing focus on the use of messenger RNA (mRNA) as a new therapeutic modality. Current clinical efforts encompassing mRNA-based drugs are directed toward infectious disease vaccines, cancer immunotherapies, therapeutic protein replacement therapies, and treatment of genetic diseases. However, challenges that impede the successful translation of these molecules into drugs are that (i) mRNA is a very large molecule, (ii) it is intrinsically unstable and prone to degradation by nucleases, and (iii) it activates the immune system. Although some of these challenges have been partially solved by means of chemical modification of the mRNA, intracellular delivery of mRNA still represents a major hurdle. The clinical translation of mRNA-based therapeutics requires delivery technologies that can ensure stabilization of mRNA under physiological conditions. Here, we (i) review opportunities and challenges in the delivery of mRNA-based therapeutics with a focus on non-viral delivery systems, (ii) present the clinical status of mRNA vaccines, and (iii) highlight perspectives on the future of this promising new type of medicine.

Internet data are being increasingly integrated into health informatics research and are becoming a useful tool for exploring human behavior. The most popular tool for examining online behavior is Google Trends, an open tool that provides information on trends and the variations of online interest in selected keywords and topics over time. Online search traffic data from Google have been shown to be useful in analyzing human behavior toward health topics and in predicting disease occurrence and outbreaks. Despite the large number of Google Trends studies during the last decade, the literature on the subject lacks a specific methodology framework. This article aims at providing an overview of the tool and data and at presenting the first methodology framework in using Google Trends in infodemiology and infoveillance, including the main factors that need to be taken into account for a strong methodology base. We provide a step-by-step guide for the methodology that needs to be followed when using Google Trends and the essential aspects required for valid results in this line of research. At first, an overview of the tool and the data are presented, followed by an analysis of the key methodological points for ensuring the validity of the results, which include selecting the appropriate keyword(s), region(s), period, and category. Overall, this article presents and analyzes the key points that need to be considered to achieve a strong methodological basis for using Google Trends data, which is crucial for ensuring the value and validity of the results, as the analysis of online queries is extensively integrated in health research in the big data era.

Google Trends in Infodemiology and Infoveillance: Methodology Framework.

BACKGROUND AND AIM The low measles vaccination coverage contributes to the re-emerging of measles in Italy. This study aimed to estimate the measles burden, expressed in Disability Adjusted Life Years (DALYs), in Umbria, for the period 2013-2018. METHODS Data on measles cases in Umbria were obtained from the MoRoNet. While data related to the resident population, were obtained from the website of the National Institute of Statistics. The estimated DALYs was calculated using the Burden of Communicable Diseases in Europe toolkit. The results are expressed in DALYs per year, per case and per 100,000 subjects, for acute illness and for sequelae. RESULTS The estimated incidence in mean for the entire period was 52.50 cases per year. Resulting in an average loss of 3.10 DALYs per year. CONCLUSIONS The data obtained from this analysis provide important information on the impact of measles in the Umbria region, and offer useful data to the Health Authorities that can be used to reduce measles incidence in the region.

The flu vaccination rate is still too low, both among healthcare providers (HCPs) and among health sciences university students. This study aims to assess the reasons of past and future flu vaccination acceptance among health sciences university students, and second, to identify what interventions would be helpful to foster acceptance of the flu vaccination among HCPs. A multicentre cross-sectional study was performed, using a validated questionnaire administered to health sciences students enrolled in 14 Italian universities. A multivariable logistic regression model was used. A total of 3131 questionnaires were collected. The statement that mandatory vaccination is required to increase adhesions to vaccinations (adjusted odds ratio [aOR] = 1.57; 95% confidence interval [CI] = 1.25-1.97), being in favour of this obligation (aOR = 7.91; 95% CI = 2.50-25.02) and considering themselves as people at risk of infection (aOR = 1.96; 95% CI = 1.46-2.64), are associated with having received the vaccination in the past flu season; on the other hand, planning to be vaccinated for the next season to avoid infecting patients is protective (aOR = 0.51; 95% CI = 0.38-0.70). This study shows which beliefs are associated with having joined the previous vaccination campaign in a large sample of HCPs. The acceptance of vaccination is an outcome behaviour resulting from a complex decision-making process. In order to implement coverage of the influenza vaccination in HCPs, it is necessary to implement awareness campaigns and provide specific information for this category of workers.

Background Vaccines are an important tool to prevent communicable diseases. Despite their importance, vaccines seem to be victims of their own success and declining levels of vaccination uptake have been recorded in Europe and Italy. For this reason, Italy introduced a new mandatory vaccination law on July 31, 2017. We aimed to validate a questionnaire to assess the opinions and knowledge of Public Health residents about this issue. Methods A team of public health residents developed a questionnaire and validated it by administering it to a panel of 10 Public Health residents, members of the Vaccines and Vaccine Hesitancy Working Group of the Public Health residents Assembly of the Italian Society of Hygiene and Preventive Medicine. Cronbach's Alpha and Cohen's Kappa tests were used to analyse results. Results The final version of the questionnaire consisted in 23 items. The validation process showed a high level of internal consistency (alpha=0,82). The tests showed a relevant level of agreement (k= 0,75 ± 0,07). Finally, the feasibility test pointed out that 80% of respondents declared the questions were clear and easy to understand. Conclusion The designed questionnaire is a valid and useful tool.

Mental health conditions are a significant contributor to the global burden of disease. The aim of this study was to explore the association between psychological disorders, Mediterranean diet (MD), and chronotype. A total of 344 participants (74% women) with a mean age of 33.5 ± 13 years were recruited. According to the Depression Anxiety Stress Scale (DASS-21) score, 22% of participants had symptoms of depression, 23% anxiety, and 10% stress. The assessment of MD adherence through the Medi-Lite score revealed that participants with psychological disorders had significantly (p < 0.05) lower MD adherence than those without these conditions. Furthermore, less than 10% of the subjects with at least one symptom reported consuming the optimal amount of fruit and vegetables, while 72% showed excessive consumption of meat and meat products. Regarding chronotype, evening subjects reported the lowest MD adherence and the highest prevalence of all three psychological disorders analyzed. A multivariate analysis showed that female gender, age, being unmarried/single, sedentary lifestyle, and low MD adherence were associated with a significantly higher risk of depression, anxiety, and stress. Future studies are needed to explore the relationship between mental health and risk factors to improve personal and global population health.
