Human parechovirus infections in patients admitted to hospital in Northern Italy, 2008-2010.

ABSTRACT: Human parechoviruses (HPeVs) infection is associated with a wide range of clinical syndromes such as respiratory, gastrointestinal, neurologic diseases, and neonatal sepsis-like illness. The main objective of this study was to investigate the epidemiology of HPeVs infection in hospitalized patients in a period of 2 years. Respiratory samples from 3,525 patients with respiratory syndrome, cerebrospinal fluid (CSF) from 340 patients with neurologic syndrome as well as CSF and plasma samples from five neonatal patients with sepsis-like illness collected from October 2008 to 2010 were tested retrospectively using HPeV-specific real-time RT-PCR. Phylogenetic analysis of VP3/VP1 region was performed on the positive samples. Fourteen out of 3,525 (0.4%) patients with respiratory syndrome and five out of five patients with sepsis-like illness were positive for HPeV. In 3/5 patients with sepsis-like illness multiple samples (e.g., stool, plasma, CSF, or respiratory samples) were available, and HPeV was found in all specimens. In contrast, no positive CSF was detected among the 340 patients with neurologic syndromes. Eleven patients (57.9%) were infected with HPeV1 strain, 7 (36.8%) with HPeV3, and 1 (5.3%) with HPeV6 strains. Ten of the 14 HPeV patients with respiratory syndrome were co-infected with other respiratory viruses (eight with rhinovirus and two with coronavirus OC43). All five patients with sepsis-like illness were less than 1 month of age and were infected with HPeV3. Although not circulating at high frequency and unlikely to cause respiratory syndrome, HPeV was associated with severe clinical syndromes in a minority of newborns.

Project description:BackgroundPrimary health care is essential for an appropriate management of heart failure (HF), a disease which is a major clinical and public health issue and a leading cause of hospitalization. The aim of this study was to evaluate the impact of different organizational factors on readmissions of patients with HF.MethodsThe study population included elderly resident in the Local Health Authority of Bologna (Northern Italy) and discharged with a diagnosis of HF from January to December 2010. Unplanned hospital readmissions were measured in four timeframes: 30 (short-term), 90 (medium-term), 180 (mid-long-term), and 365 days (long-term). Using multivariable multilevel Poisson regression analyses, we investigated the association between readmissions and organizational factors (discharge from a cardiology department, general practitioners' monodisciplinary organizational arrangement, and implementation of a specific HF care pathway).ResultsThe 1873 study patients had a median age of 83 years (interquartile range 77-87) and 55.5% were females; 52.0% were readmitted to the hospital for any reason after a year, while 20.1% were readmitted for HF. The presence of a HF care pathway was the only factor significantly associated with a lower risk of readmission for HF in the short-, medium-, mid-long- and long-term period (short-term: IRR [incidence rate ratio]=0.57, 95%CI [confidence interval]=0.35-0.92; medium-term: IRR=0.70, 95%CI=0.51-0.96; mid-long-term: IRR=0.79, 95%CI=0.64-0.98; long-term: IRR=0.82, 95%CI=0.67-0.99), and with a lower risk of all-cause readmission in the short-term period (IRR=0.73, 95%CI=0.57-0.94).ConclusionOur study shows that the HF care specific pathway implemented at the primary care level was associated with lower readmission rate for HF in each timeframe, and also with lower readmission rate for all causes in the short-term period. Our results suggest that the engagement of primary care professionals starting from the early post-discharge period may be relevant in the management of patients with HF.

Project description:BackgroundFew data are available about temporal trends of antibiotic use in hospitalized children. The aim of the current study was to investigate the pattern and trends of antibiotic use over the years 2008-2016 in the largest children's hospital in Italy.MethodsAnnual point prevalence surveys of antibiotic use were conducted by reviewing medical charts of 0-17 year-old children hospitalized for ≥48 h. Prevalence of antibiotic use was computed by year, type of ward and indication. Trends in prevalence over time were evaluated using the Cochrane-Armitage test. Possibile determinants of antibiotic use were assessed at univariate analysis and through a logistic regression model.ResultsOut of 3015 children, 1516 (50.3%) received antibiotics, 58.1% of which for medical/surgical prophylaxis. Prevalence of antibiotic use increased from 42.0% in 2008 to 56.2% in 2016 (p = 0.001). The prevalence of patients receiving antibiotics for medical prophylaxis increased from 6.1% in 2008 to 24.2% in 2016 (p < 0.001), whereas the prevalence of patients receiving antibiotics for surgical prophylaxis significantly decreased (from 13.7 to 11.8%; p = 0.04); no significant temporal trends were found in antibiotic use for treating infections. The administration of third-generation cephalosporins for surgical and medical prophylaxis significantly decreased over time, while the proportion of antibiotics prescribed to treat infections after microbiological investigations significantly increased. Year (ORadj: 1.8 in 2016 compared to 2008, p < 0.001), age (ORadj ≥1.5 in children ≥1 year, compared to infants ≤2 months, p < 0.001), length of stay (LOS) (ORadj: 1.4 in case of LOS between 8 and 30 days compared to LOS ≤ 7 days, p < 0.001), and type of ward (ORadj: ≥1.3 in intensive-care, surgical and medical-subspecialty units compared to medical units, p < 0.001) were significantly and independently associated with antibiotic use.ConclusionsComparing prevalence rates of antibiotic use among hospitals and over time should consider differences in patient characteristics, such as age, ward of hospitalization and length of stay. Over the years, we documented an improvement in the choice of antibiotics prescribed for medical and surgical prophylaxis. However, further efforts are needed to avoid antibiotic misuse for medical prophylaxis, and to reduce the empirical use of broad spectrum antibiotics.
