Epidemiology of intensive care unit-acquired sepsis in Italy: results of the SPIN-UTI network
BACKGROUND:
Sepsis is the major cause of mortality from any infectious disease worldwide. Sepsis may be the result of a healthcare associated infection (HAI): the most frequent adverse events during care delivery especially in Intensive Care Units (ICUs). The main aim of the present study was to describe the epidemiology of ICU-acquired sepsis and related outcomes among patients enrolled in the framework of the Italian Nosocomial Infections Surveillance in ICUs - SPIN-UTI project.
STUDY DESIGN:
Prospective multicenter study.
METHODS:
The SPIN-UTI network adopted the European protocols for patient-based HAI surveillance.
RESULTS:
During the five editions of the SPIN-UTI project, from 2008 to 2017, 47.0% of HAIs has led to sepsis in 832 patients. Overall, 57.0% episodes were classified as sepsis, 20.5% as severe sepsis and 22.5% as septic shock. The most common isolated microorganisms from sepsis episodes were Acinetobacter baumannii, Klebsiella pneumoniae and Pseudomonas aeruginosa. The case fatality rate increased with the severity of sepsis and the mean length of ICU-stay was significantly higher in patients with ICU-acquired sepsis than in patients without.
CONCLUSION:
Our study provides evidence that ICU-acquired sepsis occurs frequently in Italian ICU patients and is associated with a high case fatality rate and increased length of stay. However, in order to explain these findings further analyses are needed in this population of ICU patient
Attitudes of nursing home staff towards influenza vaccination: opinions and factors influencing hesitancy
Seasonal influenza is recognized to be a significant public health problem and a cause of death, especially in fragile persons. In nursing homes (NHs), vaccination for both residents and staff is the best preventive strategy. However, professionals\u2019 immunization rates are far from reaching the international recommended values. This study aims to describe the adherence and attitudes of NH staff towards flu vaccination and to explore staff hesitancy. A questionnaire was developed based on a literature review and on the 3Cs (confidence, complacency, convenience) of the WHO framework and administered among the staff of four NHs of a province in the northeast of Italy. Results demonstrated a low adherence towards annual vaccination (i.e., only 3% declared getting the flu vaccination each year). Complacency, confidence and convenience all showed a significant impact on the attitude towards vaccination both in univariate and multivariable analysis, with complacency being the most strongly associated area. The area of confidence resulted in strongly challenging factors. Only 24.8% of interviewees appeared trustful towards the efficacy of receiving immunization and 34% declared safety issues. Insights from the study can support the implementation of effective interventions to improve vaccination adherence in NHs. Specifically, increasing complacency by raising awareness related to the risks of influenza appears to be an essential strategy to effectively promote vaccination uptake
Active TB screening among homeless people attending soup kitchens in Verona (Italy)
BACKGROUND: The hard-to-reach populations, including the homeless, are particularly vulnerable to the development of active tuberculosis. According to the World Health Organization, tuberculosis rates among the homeless in industrialized Countries are up to 20 times higher if compared with the general population, representing a relevant public health problem. The aim of our study was to describe the results of an active tuberculosis screening applied in order to find out suspected active TB cases among the homeless in Verona.METHODS: As part of a partnership between the non-profit association Medici per la Pace and one of the Local Health Units of Veneto Region (ULSS 9 Scaligera) in 2018, a tuberculosis screening, based on thoracic radiographs, was offered to the homeless guests of two Verona's soup kitchens.RESULT: The studied population included 139 people, and three cases of suspected active tuberculosis, all in males, were observed. Among these, two received a diagnostic confirmation of active tuberculosis (a prevalence of 1.44% - CI: 0,17 - 5,1). Moreover, radiographic patterns of tuberculosis aftermaths were found in six additional subjects.CONCLUSION: Interventions specifically dedicated to hard-to-reach populations, can be useful in identifying tuberculosis active cases and controlling the disease in low tuberculosis burden countries. In particular, the active research of subjects, the screening carried out with mobile X-ray, and also the constant caring of the patients with active disease, could be the right method to keep under control this relevant public health problem
Is surgical debridement necessary in the diabetic foot treated with photodynamic therapy?
Background: Diabetic patients are susceptible to developing foot ulcerswith serious complications such as osteomyelitis and amputations. Treatment approaches are still empirical and the benefit of usual procedures such as surgical debridement has not been properly evaluated. Photodynamic Therapy (PDT) is a non-invasive and highly efficient method for the treatment of the diabetic foot, being able to eradicate the infection and to stimulate healing, decreasing considerably the amputation risk. In the day-to-day practice of our service, we have been faced with the question whether debridement is necessary before PDT. In here, we designed a study to answer that question. Methods: Patients were divided in two groups: In one of the groups (n = 17), debridement was performed before PDT and in the other (n = 40) only PDT treatment was performed. PDT sessions were performed once a week in all patients until healing was achieved, as indicated by visual inspection as well as by radiographic and laboratory exams. At the start of the study, the two groups had no statistical differences concerning their clinical features: average age, gender, insulin use, diabetes mellitus onset time and previous amputations. Results: PDT was effective in the treatment of 100% of the patients showing no relapses after one year of follow up. The group submitted to PDT without previous debridement had a statistically significant (p = 0.036, Mann-Whitney) shorter cure time (29 days, similar to 27%). Conclusion: Our data indicates that debridement is not necessary in the treatment of diabetic foot in patients that have enough peripheral arterial perfusion. In addition, we reproduced previous studies confirming that PDT is an efficient, safe, simple and affordable treatment method for the diabetic foot.Fundacao de Amparo a Pesquisa do Estado de Sao PauloCNPqHosp Anchieta, Fac Med ABC, Sao Bernardo Do Campo, BrazilFac Med ABC, Dept Bioquim, Santo Andre, BrazilUniv Sao Paulo, Dept Bioquim, Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Med, Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Med, Sao Paulo, BrazilFAPESP: 12/50680-5FAPESP: 13/07937-8Web of Scienc
Parentesco genético em reprodutores de tambaqui (Colossoma macropomum) baseado em marcadores de DNA: perspectivas de manejo genético na ausência de pedigree.
O controle das relações de parentesco de peixes nativos em fase inicial de domesticação é uma atividade fundamental para sustentabilidade dos recursos genéticos e fortalecimento das cadeias produtivas emergentes. O objetivo deste trabalho foi estimar o parentesco genético em reprodutores de tambaqui de uma piscicultura comercial, sem as informações de procedência e pedigree, utilizando marcadores moleculares. Quarenta e oito animais foram avaliados com seis marcadores microssatélites. O polimorfismo encontrado nessa piscicultura foi considerado moderado, com número médio de alelos de 6,5. O parentesco médio estimado foi de -0,015 a -0,02, e a curva dos genótipos reais similar à distribuição simulada de animais não aparentados. A taxa de erro foi de 7,8% a 5,5% para meios-irmãos e irmãos-completos, respectivamente. De modo geral os animais do plantel de tambaqui investigado não exibiram vínculo genético entre si o que lhes asseguram amplas possibilidades de acasalamento de reprodutores. Essa condição melhora as perspectivas de manejo na seleção de reprodutores e o descarte de acasalamento machos e fêmeas altamente consanguíneos.bitstream/item/124951/1/cnpasa-2015.pd
