Determinants of success and sustainability of the WHO multimodal hand hygiene promotion campaign, Italy, 2007-2008 and 2014.

A national hand hygiene promotion campaign based on the World Health Organization (WHO) multimodal, Clean Care is Safer Care campaign was launched in Italy in 2007. One hundred seventy-five hospitals from 14 of 20 Italian regions participated. Data were collected using methods and tools provided by the WHO campaign, translated into Italian. Hand hygiene compliance, ward infrastructure, and healthcare workers' knowledge and perception of healthcare-associated infections and hand hygiene were evaluated before and after campaign implementation. Compliance data from the 65 hospitals returning complete data for all implementation tools were analysed using a multilevel approach. Overall, hand hygiene compliance increased in the 65 hospitals from 40% to 63% (absolute increase: 23%, 95% confidence interval: 22-24%). A wide variation in hand hygiene compliance among wards was observed; inter-ward variability significantly decreased after campaign implementation and the level of perception was the only item associated with this. Long-term sustainability in 48 of these 65 hospitals was assessed in 2014 using the WHO Hand Hygiene Self-Assessment Framework tool. Of the 48 hospitals, 44 scored in the advanced/intermediate categories of hand hygiene implementation progress. The median hand hygiene compliance achieved at the end of the 2007-2008 campaign appeared to be sustained in 2014.

Community waterborne outbreak linked to a firefighting response during the COVID-19 emergency.

BACKGROUND: On 6 March 2020, a big fire in a village forced the firefighters to draw water simultaneously from many sources, including the Adige river. From 9 March, an increasing number of inhabitants reported gastrointestinal symptoms. We describe the outbreak and the challenges linked to the concurrent COVID-19 spread. METHODS: Residents with enteric symptoms and their relatives were interviewed and samples from some of the patients and public water pipelines were tested for enteric pathogens with microbiological and molecular methods. RESULTS: By 20 March, 182 people reported symptoms and 131 met the case definition. Norovirus GI/GII and other pathogens were found in human and water samples. CONCLUSIONS: Contamination of the public water network with sewage-contaminated river water through the firefighters pressurized water tank was the suspected source of the outbreak. The investigation was partly hampered due to the SARS-CoV-2 emergency. Control measures included avoiding tap water, alternative water supplies and chlorination of public water.

Effect of olive oils on biomarkers of oxidative DNA stress in Northern and Southern Europeans.

High consumption of olive oil in the Mediterranean diet has been suggested to protect DNA against oxidative damage and to reduce cancer incidence. We investigated the impact of the phenolic compounds in olive oil, and the oil proper, on DNA and RNA oxidation in North, Central, and South European populations. In a multicenter, double-blind, randomized, controlled crossover intervention trial, the effect of olive oil phenolic content on urinary oxidation products of guanine (8-oxo-guanine, 8-oxo-guanosine and 8-oxo-deoxyguanosine) was investigated. Twenty-five milliliters of three olive oils with low, medium, and high phenolic content were administered to healthy males (n=182) daily for 3 wk. At study baseline the urinary excretion of 8-oxo-guanosine (RNA oxidation) and 8-oxo-deoxyguanosine (DNA oxidation) was higher in the Northern regions of Europe compared with Central and Southern European regions (P=0.035). Urinary excretion of the 8 hydroxylated forms of guanine, guanosine, deoxyguanosine and their nonoxidized forms were not different when comparing olive oils with low, medium, and high phenolic content given for 2 wk. Testing the effect of oil from urinary 8-oxo-deoxyguanosine changes from baseline to post-treatment showed a reduction of DNA oxidation by 13% (P=0.008). These findings support the idea that ingestion of olive oil is beneficial and can reduce the rate of oxidation of DNA. This effect is not due to the phenolic content in the olive oil. The higher DNA and RNA oxidation in Northern European regions compared with that in Central and Southern regions supports the contention that olive oil consumption may explain some of the North-South differences in cancer incidences in Europe.

Changes in LDL fatty acid composition as a response to olive oil treatment are inversely related to lipid oxidative damage: The EUROLIVE study.

OBJECTIVE: The aim of our study was to assess the changes in the fatty acid composition of low density lipoproteins (LDL) after sustained consumption of olive oil at real-life doses (25 mL/day) and their relationship with lipid oxidative damage. METHODS: A multi-center randomized, cross-over, clinical trial with 3 similar types of olive oils, but with differences in the phenolic content, was conducted on 200 healthy European subjects. Intervention periods were of 3 weeks separated by 2-week washout periods. The LDL fatty acid content was measured in samples drawn at baseline and after the last intervention period. RESULTS: After olive oil ingestion oleic acid concentration in LDL increased (1.9%; p < 0.001) and those of linoleic (1.1%; p < 0.002) and arachidonic acid (0.5%; p < 0.001) decreased. Monounsaturated/polyunsaturated fatty acid and oleic/linoleic acid ratios in LDL increased after olive oil consumption. An inverse relationship between the oleic/linoleic acid ratio and biomarkers of oxidative stress was observed. One unit increase in the oleic/linoleic acid ratio was associated with a decrease of 4.2 microg/L in plasma isoprostanes. CONCLUSION: Consumption of olive oil at real-life doses improved the fatty acid profile in LDL, the changes being associated with a reduction of the oxidative damage to lipids.

The effect of polyphenols in olive oil on heart disease risk factors: a randomized trial.

BACKGROUND: Virgin olive oils are richer in phenolic content than refined olive oil. Small, randomized, crossover, controlled trials on the antioxidant effect of phenolic compounds from real-life daily doses of olive oil in humans have yielded conflicting results. Little information is available on the effect of the phenolic compounds of olive oil on plasma lipid levels. No international study with a large sample size has been done. OBJECTIVE: To evaluate whether the phenolic content of olive oil further benefits plasma lipid levels and lipid oxidative damage compared with monounsaturated acid content. DESIGN: Randomized, crossover, controlled trial. SETTING: 6 research centers from 5 European countries. PARTICIPANTS: 200 healthy male volunteers. MEASUREMENTS: Glucose levels, plasma lipid levels, oxidative damage to lipid levels, and endogenous and exogenous antioxidants at baseline and before and after each intervention. INTERVENTION: In a crossover study, participants were randomly assigned to 3 sequences of daily administration of 25 mL of 3 olive oils. Olive oils had low (2.7 mg/kg of olive oil), medium (164 mg/kg), or high (366 mg/kg) phenolic content but were otherwise similar. Intervention periods were 3 weeks preceded by 2-week washout periods. RESULTS: A linear increase in high-density lipoprotein (HDL) cholesterol levels was observed for low-, medium-, and high-polyphenol olive oil: mean change, 0.025 mmol/L (95% CI, 0.003 to 0.05 mmol/L), 0.032 mmol/L (CI, 0.005 to 0.05 mmol/L), and 0.045 mmol/L (CI, 0.02 to 0.06 mmol/L), respectively. Total cholesterol-HDL cholesterol ratio decreased linearly with the phenolic content of the olive oil. Triglyceride levels decreased by an average of 0.05 mmol/L for all olive oils. Oxidative stress markers decreased linearly with increasing phenolic content. Mean changes for oxidized low-density lipoprotein levels were 1.21 U/L (CI, -0.8 to 3.6 U/L), -1.48 U/L (-3.6 to 0.6 U/L), and -3.21 U/L (-5.1 to -0.8 U/L) for the low-, medium-, and high-polyphenol olive oil, respectively. LIMITATIONS: The olive oil may have interacted with other dietary components, participants' dietary intake was self-reported, and the intervention periods were short. CONCLUSIONS: Olive oil is more than a monounsaturated fat. Its phenolic content can also provide benefits for plasma lipid levels and oxidative damage.

[Health profile of a population as a predictor of health resources utilization: results of the implementation of an epidemiologic model for needs analysis]. / Profilo di salute di una popolazione come predittore dell'utilizzo di risorse sanitarie: risultati dell'applicazione di un modello epidemiologico per l'analisi dei bisogni.

The integration of the scientific researches in the assistance process is one of the most important challenges that is currently set to the health operators. In this paper a model for the health needs-assessment will be applied to verify if and how the prevalence of some classical risk factors for cardiovascular disease foretells mortality and hospitalisation episodes at 3 years, and if it could express the health need of that population. The "sanitary history" of 1704 subjects, enrolled in 1996 during the Brisighella Study, has been followed. We know the health profile of these subjects at 1996 and data about their hospitalizations, mortality, and general assistance from 1996 to 1999. In this population the risk of cardiovascular disease is inferior to that esteemed by the hospitalisation rate, attributable mostly to a little group of subjects with well-defined characteristics of exposure. The resources spent on a hospitalization do not adequately describe either the sanitary need nor the relief load and the "cost" associated to the disease. The methodology used allows to explore in detail the relative weight of the different subjects involved in the sanitary assistance in order to better reach the objective of producing the maximum quantity of benefits for the patient at the smallest possible quantity of risk.

Laboratory procedures for the diagnosis of tuberculosis: a survey in ten Italian Regions.

The characteristics of laboratories performing tuberculosis (TB) diagnostic procedures were investigated in ten Italian Regions, through a mailed questionnaire. Three hundred and eighty laboratories answered (70.8 % response rate), 250 of which performed directly at least one TB diagnostic procedure. Standard criteria concerning microscopy, culture, identification, and drug susceptibility testing were frequently not satisfied, particularly those related to the volume of activity (32 % of laboratories performing microscopy examined 10 samples and 36 % of those performing culture performed 20 cultures per week), processing time, biosafety requirements and participation to internal/external quality control programs. The survey' results highlight the need to promote the adoption of standardized procedures and to centralize the mycobacteriology testing in a reduced number of high quality laboratories, in order to improve diagnostic accuracy, resource management and quality of surveillance data.

Asymptomatic massive hypertriglyceridemia in an octogenarian.

OBJECTIVE: To report the case of an 85-year-old man with asymptomatic massive hypertriglyceridemia (MHTG). CLINICAL PRESENTATION AND INTERVENTION: Our case was a non-smoker, healthy 85-year-old Caucasian male, with no excessive alcohol intake and no evidence of an excessive sedentary lifestyle, body mass index = 23.2 kg/m(2), BP = 125/85 mm Hg and plasma triglyceride (TG) >1,000 mg/dl. The MHTG was an incidental finding at the age of 70. He had no cardiovascular disease, xanthomas, xanthelasmas or keratic precipitate. During the last 15 years, his average TG plasma levels showed a significant variability independent of specific diet treatment and fibrate therapy. Liver ultrasound examination excluded hepatomegaly and fatty degeneration. Carotid artery ultrasound showed only intimal thickening in both carotid bifurcations. CONCLUSION: In this patient, MHTG had been silent for many years, with no evidence of coronary heart disease and liver fatty degeneration, both typical complications present in MHTG subjects with low high-density lipoprotein. Hence, this case must be considered as a rarity.

Cerebrovascular disease in Italy and Europe: it is necessary to prevent a 'pandemia'.

In Italy and Europe, strokes are the third most common cause of death and resulting invalidity. In the ever-increasing 80-years-old-and-over population, strokes become more serious due to the clinical presentation during the acute phase and the ten times higher mortality, but also in relation to the twice as high resulting disability as for younger subjects. With the growing number of ailing and not-self-sufficient elderly, other resources will have to be relocated to this field of public health. Then, the dependence index and the ensuing equivalence based on estimates for the first decades of 2000 will create more difficulties in retrieving the funds for social policies. However, stroke prevention is possible both through correct behavioural habits and pharmacological means. Besides the well-known preventive effects of an adequate antihypertensive, antidiabetic and/or antiaggregant/anticoagulant therapy, there is increasing evidence of the effectiveness of statin therapy in stroke prevention. Subjects with a personal history of cerebrovascular events have an increased coronary risk and vice versa. The greatest part of the risk factors for the cerebrovascular disease coincides with those for cardiovascular disease, for which the correction of the former automatically involves a reduction in incidence of both pathologies. In this context, a statin's rational use can therefore represent an important tool for the combined prevention of the two pathologies. Finally, different hypotheses link the origin of Alzheimer's disease to that of progressive cerebrovascular dementia caused by cerebral microcirculation damage. The aim of this review is to resume the actual knowledge about the epidemiology of cerebrovascular disease in Italy and Europe, and about the means available to prevent this phenomenon.

In this context, a statin's rational use can therefore represent an important tool for the combined prevention of the two pathologies. Finally, different hypotheses link the origin of Alzheimer's disease to that of progressive cerebrovascular dementia caused by cerebral microcirculation damage. It is plausible that the application of a suitable early prevention of the cerebrovascular pathology could bring to a more late slatentisation and less serious demonstrations of Alzheimer's disease, when this is destined to develop.
