RESUMEN
BACKGROUND: Even if Meares-Stamey 4-glass (M&S) test is regarded a decisive tool for diagnosing prostatitis its use is only rarely performed in everyday clinical practice. Here, we analyze if the diagnostic yield of the M&S test could be improved by a pre-test categorization of patients due to undergo a M&S test. METHODS: All clinical and microbiological data of patients who underwent M&S test in two urological centers from January 2004 to December 2021 were analyzed in this retrospective cohort study. One center has a dedicated staff member for the study of prostatitis (Cohort I), while the other center is a general urological unit (Cohort II). All patients were divided into 3 groups on the basis of the assembled data: patients with symptoms related to prostatitis only (Group I), patients with symptoms related to both prostatitis and BPH (Group II), patients with symptoms related to BPH only (Group III). The rates of positive microbiological results in each group were compared. RESULTS: In the whole period, 9347 patients were analyzed and categorized as follows: Group I, 1884; Group II, 5151; Group III, 2312. Three-thousand and eight-hundred twenty-three patients showed positive culture results (40.9%). The most common isolated species was Escherichia coli (49.7%), followed by Enteroccus spp. (31.8%). The rates of positive M&S tests in the different symptom groups were: Group I, 1532 (81.4%); Group II, 1494 (29.0%); Group III, 797 (34.4%). The overall rate of positive M&S tests in each urology center showed that the center with a staff member who is dedicated to prostatitis studies (Cohort I) had a significantly higher rate of positive M&S tests than the general urological department (Cohort II) (64.3% vs 31.4%; p < 0.001). CONCLUSIONS: Symptom-based patient selection and dedicated staff members will increase the diagnostic yield of the M&S test and reduce the number of unnecessary tests.

This paper introduces a comprehensive dataset on West Nile virus outbreaks that have occurred in Italy from September 2012 to November 2022. We have digitized bulletins published by the Italian National Institute of Health to demonstrate the potential utilization of this data for the research community. Our aim is to establish a centralized open access repository that facilitates analysis and monitoring of the disease. We have collected and curated data on the type of infected host, along with additional information whenever available, including the type of infection, age, and geographic details at different levels of spatial aggregation. By combining our data with other sources of information such as weather data, it becomes possible to assess potential relationships between West Nile virus outbreaks and environmental factors. We strongly believe in supporting public oversight of government epidemic management, and we emphasize that open data play a crucial role in generating reliable results by enabling greater transparency.

On 20 September 2022, the Ministry of Health in Uganda, together with the World Health Organization-Regional Office for Africa (WHO AFRO) confirmed an outbreak of EVD due to Sudan ebolavirus in Mubende District, after one fatal case was confirmed. Real-time information are needed to provide crucial information to understand transmissibility, risk of geographical spread, routes of transmission, risk factors of infection, and provide the basis for epidemiological modelling that can inform response and containment planning to reduce the burden of disease. We made an effort to build a centralized repository of the Ebola virus cases from verified sources, providing information on dates of symptom onset, locations (aggregated to the district level), and when available, the gender and status of hospitals, reporting bed capacity and isolation unit occupancy rate according to the severity status of the patient. The proposed data repository provides researchers and policymakers timely, complete, and easy-accessible data to monitor the most recent trends of the Ebola outbreak in Ugandan districts with informative graphical outputs. This favors a rapid global response to the disease, enabling governments to prioritize and adjust their decisions quickly and effectively in response to the rapidly evolving emergency, with a solid data basis.
RESUMEN
This world outbreak of Monkeypox (MPX) infections outside Africa emerged on May 2022 in Europe and spread worldwide with unique characteristics: inter-human contagion and infection in men without specific previous immunization, prevalently men-who-have-sex-with-men (MSM). Phylogenetic analysis confirmed a unique clade, the West African clade, subclade IIb. On August 30, WHO stated 48 895 laboratory confirmed cases from 101 different countries, of which 28 050 were in Europe. It has therefore become important to define new epidemiological indices. Starting from our new surveillance system EpiMPX open data, we defined an early R0 measure, using European ECDC confirmed cases from the epidemic start to the end of August 2022; our early R0 pooled median is 2.44, with high variability between countries. We observed the higher R0 in Portugal and Germany, followed by Italy, Spain, and France. Anyway, these high estimates refer to the MSM group rather than to the general population. Early estimation of R0 can be used to support the epidemiological understanding of transmission dynamics and contain MPX from spreading in naive populations and core groups with risk factors. MPX is in an evolving situation with much to learn and to do to combat the current epidemic outbreak.

In recent years, the unprecedented spread of the Avian Influenza Viruses (AIVs) among birds and mammals has caused devastation in animal populations, including poultry, wild birds, and some mammals, damaging farmers' livelihoods and the food trade. Given the urgency of the situation, it is particularly important that scientists and the public can access research results and data as soon as possible. The main aim of this study is to present a global open-access dataset of Avian Influenza outbreaks to enable researchers and policymakers (i) to rapidly detect, and respond to animal outbreaks as the first line of defense; (ii) to conduct epidemiological and virological investigations around animal outbreaks and human infections; and (iii) to communicate the risk. We show the potential use of this dataset to the research community by analyzing the most updated information on past and current Highly Pathogenic Avian Influenza (HPAI) outbreaks in domestic poultry and wild birds over the period from October 2021 to July 2023 in Italy. In addition, we applied indices borrowed from Economics (such as Homogeneity, Specialization, and Location Index) to the wild birds dataset to show their possible usage in epidemiology.
RESUMEN
Background: The current out-of-Africa 2022 outbreak of Monkeypox requires a coordinated, international response through the rapid sharing of data and research results, as we have seen with COVID-19 and the previous Ebola and Zika outbreaks, which demonstrated how important real-world data are to inform public health, to create surveillance systems, to determine policy decisions and to improve clinical trials. Objectives: To support global response efforts by providing public access to real-time Monkeypox-related data for effective use of open data that could accelerate scientific knowledge and discoveries in terms of understanding, preventing, and treating the disease. In practice, to create a new surveillance system easy to consult and utilize. Study design: This work aims to build a surveillance system, namely EpiMPX, that allows researchers and policymakers to monitor the impact of Monkeypox in Europe, with a special focus on the epidemic trends in the Italian regions, based on an open-access database containing information on the laboratory confirmed Monkeypox cases reported by EU/EEA countries and updated once a week. In addition, users will be provided open-access R codes to estimate key epidemiological parameters such as the reproduction number (updating the Serial Interval distribution when new estimates will be published) and produce real-time results on their devices. Results: EpiMPX monitors the space-time distribution of cases and their characteristics, such as age, gender, symptoms, clinical status, and sexual orientation, when available. Even if it is currently too early for reliable calculation of epidemiological parameters, we estimated reproduction number R t in European countries with more than 28 days of observed incidence, assuming that the Serial Interval (SI) early estimate in Italy is valid for other countries too. This provides a direct visual assessment of the geographic distribution of risk areas as well as insights into the evolution of the outbreak over time. Italian data were evaluated concerning gender, region prevalence and cumulative data. Conclusions: The proposed EpiMPX surveillance system provides an overview of the European and Italian Monkeypox epidemiological situation with an open-access database to support epidemiological understanding of the origins and transmission dynamics of the disease with informative graphical outputs. These data confirmed the prevalent expression of Monkeypox within males, both in Europe and Italy. European MSM patients were affected by Monkeypox in a high percentage, confirming close sexual contact and possible sexual transmission. For the first time, Italian data on the regional distribution of cases and gender distribution were graphically evaluated. The data and research results are freely available and can be easily enriched to provide a prompt response to the scientific community and accelerate global efforts to contain the Monkeypox virus.
RESUMEN
During the early stages of an epidemic, obtaining reliable data is a challenge, especially on a global scale. The COVID-19 pandemic has underlined the importance of having "open data" (i.e., data which are made accessible and available in a standardized machine-readable format and under a license that allows it to be re-used and reshared) to inform health policy decisions and improve clinical trials. The main goal of our work is to provide effective, timely and comprehensive data to investigate this emerging virus, i.e., the acute hepatitis of unknown origin in children. These data can be used: 1) to conduct real-time situation analysis, and early and timely diagnosis for effective containment; 2) to facilitate coordination and collaboration between national and local governments; 3) to inform citizens on the spread of the disease in the world; and 4) to support governments in the future prevention decisions.
RESUMEN
Despite the stunning speed with which highly effective and safe vaccines have been developed, the emergence of new variants of SARS-CoV-2 causes high rates of (re)infection, a major impact on health care services, and a slowdown to the socio-economic system. For COVID-19, accurate and timely forecasts are therefore essential to provide the opportunity to rapidly identify risk areas affected by the pandemic, reallocate the use of health resources, design countermeasures, and increase public awareness. This paper presents the design and implementation of an approach based on autoregressive models to reliably forecast the spread of COVID-19 in Italian regions. Starting from the database of the Italian Civil Protection Department (DPC), the experimental evaluation was performed on real-world data collected from February 2020 to March 2022, focusing on Calabria, a region of Southern Italy. This evaluation shows that the proposed approach achieves a good predictive power for out-of-sample predictions within one week (R-squared > 0.9 at 1 day, R-squared > 0.7 at 7 days), although it decreases with increasing forecasted days (R-squared > 0.5 at 14 days).
RESUMEN
Purpose: Prostate calcifications are a common finding during transrectal prostate ultrasound in both healthy subjects and patients, but their etiopathogenesis and clinical significance are not fully understood. We aimed to establish a new methodology for evaluating the role of microbial biofilms in the genesis of prostate calcifications. Materials and Methods: Ten consecutive patients who had undergone radical prostatectomy were enrolled in this study. All of the patients presented with prostate calcifications during transrectal ultrasound evaluation before surgery and underwent Meares-Stamey tests and clinical evaluation with the National Institutes of Health Chronic Prostatitis Symptom Index and the International Prostate Symptom Score. At the time of radical prostatectomy, the prostate specimen, after removal, was analyzed with ultrasonography under sterile conditions in the operating room. Core biopsy specimens were taken from the site of prostate calcification and subjected to ultrastructural and microbiological analysis. Results: The results of the Meares-Stamey test showed only 1 of 10 patients (10%) with positive cultures for Escherichia coli. Two of five patients (40%) had positive cultures from prostate biopsy specimens. Enterococcus faecalis, Enterococcus raffinosus, and Citrobacter freundii were isolated. Ultrastructural analysis of the prostate biopsy specimens showed prostate calcifications in 6 of 10 patients (60%), and a structured microbial biofilm in 1 patient who had positive cultures for E. faecalis and E. raffinosus. Conclusions: Although the findings are supported by a low number of patients, this study highlights the validity of the proposed methodology for investigating the role of bacterial biofilms in the genesis of prostate calcification.

PURPOSE: We aim to evaluate the efficacy of pollen extract in association with vitamins in patients affected by chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and to evaluate the level of the pro-inflammatory mediators interleukin (IL)-6, IL-8, and IL-10. MATERIALS AND METHODS: Patients diagnosed with CP/CPPS between January and December 2015 were enrolled in this study. Participants were randomly assigned to receive oral capsules of pollen extract and vitamins (group A) or bromelain (group B) for 3 months. At the enrolment time and 3 months after enrolment, all patients completed questionnaires (the National Institutes of Health Chronic Prostatitis Symptom Index [NIH-CPSI] and the Short Form-36 and underwent urological examinations and microbiological evaluation. Levels of IL-6, IL-8, and IL-10 were evaluated in seminal plasma. RESULTS: Sixty-five male patients (mean age of 32.7±4.7 years) were analysed (group A, n=32; group B, n=33). At the follow-up examination, 24 of the 32 patients in group A showed a significant reduction in the NIH-CPSI total score compared with 8 of the 33 patients in the bromelain group (p<0.001). Moreover, the mean level of IL-8 was significantly lower in the pollen extract and vitamins group when compared with the bromelain group (298 pg/mL vs. 736 pg/mL, respectively; p<0.001). In group A we found a statistically significant reduction in the levels of IL-8 between enrolment and the follow-up visit (878 pg/mL vs. 298 pg/mL, respectively; p<0.001). CONCLUSIONS: Treatment with pollen extract and vitamins improved the quality of life in CP/CPPS patients by reducing the levels of pro-inflammatory IL-8.
RESUMEN
We evaluated, in a preliminary study, the efficacy of umbelliferone, arbutin, and N-acetylcysteine to inhibit biofilm formation on urinary catheter. We used 20 urinary catheters: 5 catheters were incubated with Enterococcus faecalis (control group); 5 catheters were incubated with E. faecalis in presence of umbelliferone (150 mg), arbutin (60 mg), and N-acetylcysteine (150 mg) (group 1); 5 catheters were incubated with E. faecalis in presence of umbelliferone (150 mg), arbutin (60 mg), and N-acetylcysteine (400 mg) (group 2); and 5 catheters were incubated with E. faecalis in presence of umbelliferone (300 mg), arbutin (60 mg), and N-acetylcysteine (150 mg) (group 3). After 72 hours, planktonic microbial growth and microorganisms on catheter surface were assessed. In the control group, we found a planktonic load of ≥10(5) CFU/mL in the inoculation medium and retrieved 3.69 × 10(6) CFU/cm from the sessile cells adherent to the catheter surface. A significantly lower amount in planktonic (p < 0.001) and sessile (p = 0.004) bacterial load was found in group 3, showing <100 CFU/mL and 0.12 × 10(6) CFU/cm in the incubation medium and on the catheter surface, respectively. In groups 1 and 2, 1.67 × 10(6) CFU/cm and 1.77 × 10(6) CFU/cm were found on catheter surface. Our results document that umbelliferone, arbutin, and N-acetylcysteine are able to reduce E. faecalis biofilm development on the surface of urinary catheters.
RESUMEN
Asymptomatic bacteriuria (ABU) is a common clinical condition that often leads to unnecessary antimicrobial use. The reduction of antibiotic overuse for ABU is consequently an important issue for antimicrobial stewardship and to reduce the emergence of multidrug resistant strains. There are two issues in everyday urological practice that require special attention: the role of ABU in pre-operative prophylaxis and in women affected by recurrent urinary tract infections (rUTIs). Nowadays, this is the time to think over our practice and change our way of thinking. Here, we aimed to summarize the current literature knowledge in terms of ABU management in patients undergoing urological surgery and in patients with rUTIs. In the last years, the approach to patient with ABU has changed totally. Prior to all surgical procedures that do not enter the urinary tract, ABU is generally not considered as a risk factor, and screening and treatment are not considered necessary. On the other hand, in the case of all procedures entering the urinary tract, ABU should be treated in line with the results of a urine culture obtained before the procedure. In patients affected by rUTIs, ABU can even have a protective role in preventing symptomatic recurrence, particularly when Enterococcus faecalis (E. faecalis) has been isolated.
RESUMEN
BACKGROUND: Women suffering from recurrent urinary tract infections (rUTIs) are routinely treated for asymptomatic bacteriuria (AB), but the consequences of this procedure on antibiotic resistance are not fully known. The aim of this study was to evaluate the impact of AB treatment on antibiotic resistance among women with rUTIs. METHODS: The study population consisted of 2 groups of women who had previously been enrolled in a randomized clinical trial: group A was not treated, and group B was treated. All women were scheduled for follow-up visits every 6 months, or more frequently if symptoms arose. Microbiological evaluation was performed only in symptomatic women. All women were followed up for a mean of 38.8 months to analyze data from urine cultures and antibiograms. RESULTS: The previous study population consisted of 673 women, but 123 did not attend the entire follow-up period. For the final analysis, 257 of the remaining 550 patients were assigned to group A, and 293 to group B. At the end of follow-up, the difference in recurrence rates was statistically significant (P < .001): 97 (37.7%) in group A versus 204 (69.6%) in group B. Isolated Escherichia coli from group B showed higher resistance to amoxicillin-clavulanic acid (P = .03), trimethoprim-sulfamethoxazole (P = .01), and ciprofloxacin (P = .03) than that from group A. CONCLUSIONS: This study shows that AB treatment is associated with a higher occurrence of antibiotic-resistant bacteria, indicating that AB treatment in women with rUTIs is potentially dangerous.

INTRODUCTION: Chronic bacterial prostatitis (CBP) is reported to be a common finding in men with acquired premature ejaculation (PE). The impact of different pathogens on PE development in chronic prostatitis patients is, however, unknown. AIM: To assess a possible link between CBP caused by Chlamydia trachomatis (Ct) and PE. METHODS: A consecutive series of 317 patients with clinical and instrumental diagnosis of CBP due to Ct was enrolled (group A) and compared with data obtained from a control group of 639 patients with CBP caused by common uropathogen bacteria (group B). Prostatitis symptoms were investigated with the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), while the ejaculatory status of patients was assessed using the PE Diagnostic Tool (PEDT). MAIN OUTCOME MEASURES: All participants were asked to complete the NIH-CPSI, the International Index of Erectile Function-15 erectile function domain (IIEF-15-EFD), the PEDT, and the Short Form (SF)-36 questionnaires. RESULTS: Patient groups A and B had comparable scores of NIH-CPSI (P = 0.07), IPSS (P = 0.32), and IIEF-15-EFD (P = 0.33) tests. PE was assessed in 118 patients in group A (37.2%) and in 73 subjects in group B (11.5%). The two groups are different in terms of PE prevalence (P < 0.0002). Compared with group B, group A showed significantly higher scores of the PEDT test (11.3 [±2.6] vs. 4.5 [±2.9], P < 0.0001) and lower scores of the SF-36 tool (96.5 [±1.1] vs. 99.7 [±1.3], P < 0.0001). In our multivariate model assessment, being positive for a Ct infection marker was independently associated with the PEDT score even after adjusting for age, smoking habit, body mass index, and education level (adjusted odds ratio = 3.21; 95% confidence interval: 2.02-4.27; P < 0.003). CONCLUSIONS: Patients affected by CBP due to Ct infection reported higher prevalence of PE and lower quality of life when compared with patients affected by CBP caused by traditional uropathogenic bacteria.

PURPOSE: To investigate the relationship between human papillomavirus (HPV) infection and prostatitis-related symptoms. MATERIALS AND METHODS: All young heterosexual patients with prostatitis-related symptoms attending the same Center from January 2005 to December 2010 were eligible for this case-control study. Sexually active asymptomatic men were considered as the control group. All subjects underwent clinical examination, Meares-Stamey test and DNA-HPV test. Patients with prostatitis-related symptoms and asymptomatic men were compared in terms of HPV prevalence. Moreover, multivariable Cox proportional hazards regression analysis was performed to determine the association between HPV infection and prostatitis-related symptoms. RESULTS: Overall, 814 out of 2,938 patients (27.7%) and 292 out of 1,081 controls (27.0%) proved positive to HPV. The HPV genotype distribution was as follows: HR-HPV 478 (43.3%), PHR-HPV 77 (6.9%), LR-HPV 187 (16.9%) and PNG-HPV 364 (32.9%). The most common HPV genotypes were: 6, 11, 16, 26, 51, 53 and 81. No difference was found between the two groups in terms of HPV infection (OR 1.03; 95% CI 0.88-1.22; p = 0.66). We noted a statistically significant increase in HPV infection over the period 2005 to 2010 (p < 0.001) in both groups. Moreover, we found a statistically significant increase in HPV 16 frequency from 2005 to 2010 (p = 0.002). CONCLUSIONS: This study highlights that prostatitis-like symptoms are unrelated to HPV infection. Secondary, we highlight the high prevalence of asymptomatic HPV infection among young heterosexual men.

OBJECTIVES: To develop and externally validate a novel nomogram predicting recurrence risk probability at 12 months in women after an episode of urinary tract infection. METHODS: The study included 768 women from Santa Maria Annunziata Hospital, Florence, Italy, affected by urinary tract infections from January 2005 to December 2009. Another 373 women with the same criteria enrolled at Santa Chiara Hospital, Trento, Italy, from January 2010 to June 2012 were used to externally validate and calibrate the nomogram. Univariate and multivariate Cox regression models tested the relationship between urinary tract infection recurrence risk, and patient clinical and laboratory characteristics. The nomogram was evaluated by calculating concordance probabilities, as well as testing calibration of predicted urinary tract infection recurrence with observed urinary tract infections. Nomogram variables included: number of partners, bowel function, type of pathogens isolated (Gram-positive/negative), hormonal status, number of previous urinary tract infection recurrences and previous treatment of asymptomatic bacteriuria. RESULTS: Of the original development data, 261 out of 768 women presented at least one episode of recurrence of urinary tract infection (33.9%). The nomogram had a concordance index of 0.85. The nomogram predictions were well calibrated. This model showed high discrimination accuracy and favorable calibration characteristics. In the validation group (373 women), the overall c-index was 0.83 (P = 0.003, 95% confidence interval 0.51-0.99), whereas the area under the receiver operating characteristic curve was 0.85 (95% confidence interval 0.79-0.91). CONCLUSIONS: The present nomogram accurately predicts the recurrence risk of urinary tract infection at 12 months, and can assist in identifying women at high risk of symptomatic recurrence that can be suitable candidates for a prophylactic strategy.

INTRODUCTION: Even if some evidence exists of a positive correlation between regular intake of phytoestrogens, polyphenols, antioxidants and women's sexual health, there is not a study addressing the potential correlation between daily apple consumption and women's sexual function. We aim to assess whether there is a tie between daily apple intake and sexual function in a sample of healthy young sexually active Italian women, not complaining of any sexual disorders. MATERIALS AND METHODS: Seven hundred and thirty-one women (mean age 31.9, range 18-43) were enrolled in this cross-sectional study (from September 2011 to April 2012). All participants completed anonymously the Female Sexual Function Index (FSFI) and were asked to report on their amount of daily apple consumption and their eating habits. On the basis of apple consumption all women were split into two groups: Group A--regular daily apple consumption, Group B--no regular apple consumption (<1 apple/day). The main outcome measure was the FSFI questionnaire result. RESULTS: Three hundred and forty-three women reported a regular daily apple intake and were classified in Group A, while 388 were included in Group B. Group A had a significantly higher total (p = 0.001; Cohen's d = 3.39) and lubrication domain (p = 0.001; Cohen's d = 3.02) FSFI scores than participants in Group B. Multivariate analysis demonstrated that daily apple intake must be considered as an independent parameter (p = 0.002) in predicting a better score at questionnaire examination. DISCUSSION: This study suggests a potential relationship between regular daily apple consumption and better sexuality in our young women population.

BACKGROUND: Coryneform bacteria constitute an important segment of male urogenital microbiota. They have been generally considered as saprophytes, although some species have been associated with prostatitis as well. At the same time, biofilm infections have been suspected as a cause of prostatitis. OBJECTIVE: To identify a set of coryneform bacteria isolated from semen of either healthy men or prostatitis patients applying different methods to reveal inter-assay variability and to determine their ability of adhesion and biofilm production. DESIGN: Coryneform bacteria were identified by API Coryne 2.0 biochemical identification system and 16S rDNA sequencing using different primer sets. Quantitative assessment of biofilm production was performed using crystal violet binding assay method. RESULTS: The most common species were Corynebacterium seminale, C. minutissimum, and Dermabacter hominis. Altogether 14 species and related genera were found. We observed the best inter-assay agreement when identifying C. seminale. Biofilm was observed in 7 out of 24 strains. The biofilm-producing strains belonged to Arthrobacter cumminsii, Dermabacter hominis, C. minutissimum, and Actinomyces neuii. No differences were found between the strains originating from prostatitis patients and healthy men. Dermabacter hominis strains were more potent biofilm producers than C. seminale strains (p=0.048). CONCLUSIONS: We can conclude that a wide variety of coryneform bacteria can be found from the male genital tract, although their exact identification is problematic due to insufficient representation in databases. Nearly one third of the strains are able to form biofilm that may give them an advantage for surviving several host- and treatment-related conditions.
