Pluralità identitarie tra bioetica e biodiritto

Il C.I.R.B. (Centro Interuniversitario di Ricerca Bioetica), cui aderiscono tutte le Università campane, è un organismo di ricerca nel quale – con metodo rigorosamente scientifico, grazie al concorso di qualificati cultori delle varie discipline interessate e in un clima di costante e costruttivo dialogo con i rappresentanti delle diverse posizioni culturali – è possibile delineare le trame di una serena e ponderata riflessione comune su tematiche che coinvolgono l’identità stessa della persona umana e il destino delle generazioni future

SSEP amplitude accurately predicts both good and poor neurological outcome early after cardiac arrest; a post-hoc analysis of the ProNeCA multicentre study

AIM: To assess if, in comatose resuscitated patients, the amplitude of the N20 wave (N20amp) of somatosensory evoked potentials (SSEP) can predict 6-months neurological outcome.SETTING: Multicentre study in 13 Italian intensive care units.METHODS: The N20amp in microvolts (muV) was measured at 12h, 24h, and 72h from cardiac arrest, along with pupillary reflex (PLR) and a 30-min EEG classified according to the ACNS terminology. Sensitivity and false positive rate (FPR) of N20amp alone or in combination were calculated.RESULTS: 403 patients (age 69[58-68] years) were included. At 12h, an N20amp >3muV predicted good neurological outcome (Cerebral Performance Categories [CPC] 1-2) with 61[50-72]% sensitivity and 11[6-18]% FPR. Combining it with a benign (continuous or nearly continuous) EEG increased sensitivity to 91[82-96]%. For poor outcome (CPC 3-5), an N20Amp ≤0.38muV, ≤0.73muV and ≤1.01muV at 12h, 24h, and 72h, respectively, had 0% FPR with sensitivity ranging from 61[51-69]% and 82[76-88]%. Sensitivity was higher than that of a bilaterally absent N20 at all time points. At 12h and 24h, a highly malignant (suppression or burst-suppression) EEG and bilaterally absent PLR achieved 0% FPR only when combined with SSEP. A combination of all three predictors yielded a 0[0-4]% FPR, with maximum sensitivity of 44[36-53]%.CONCLUSION: At 12h from arrest, a high N20Amp predicts good outcome with high sensitivity, especially when combined with benign EEG. At 12h and 24h from arrest a low-voltage N20amp has a high sensitivity and is more specific than EEG or PLR for predicting poor outcome

Trauma and amyotrophic lateral sclerosis: a european population-based case-control study from the EURALS consortium

International audienceOBJECTIVES:To assess the association between amyotrophic lateral sclerosis (ALS) and previous traumatic events, age of trauma, and site of injury.METHODS:A population-based case-control study was performed in five European countries (Italy, Ireland, France, United Kingdom, Serbia). Newly diagnosed ALS patients and matched controls were interviewed to collect relevant demographic factors and exposures. Key clinical features at diagnosis were collected in ALS patients. Trauma was any accidental event causing an injury. Injuries were dated and classified according to cause, severity, type, site, and complications. All exposures were censored five years before symptoms onset. Risks were computed as odds ratios (OR) with 95% confidence intervals (CI) using univariate and multivariate conditional logistic regression models.RESULTS:Five hundred and seventy-five ALS patients and 1150 controls were interviewed. Disabling traumatic events predominated in the cases (OR 1.54 (95% CI 1.24-1.92)) and maintained significance after adjustment, with a significant gradient. A history of 2 + head injuries was associated with an almost three-fold increased risk of ALS. The risk was almost two-fold when trauma occurred at age 35-54 years. Site of injury was uneventful.CONCLUSIONS:Traumatic events leading to functional disability or confined to the head are risk factors for ALS. Traumatic events experienced at age 35-54 years carry the highest risk

Dietary polyphenol intake is associated with HDL-cholesterol and a better profile of other components of the metabolic syndrome: a PREDIMED-Plus sub-study

Dietary polyphenol intake is associated with improvement of metabolic disturbances. The aims of the present study are to describe dietary polyphenol intake in a population with metabolic syndrome (MetS) and to examine the association between polyphenol intake and the components of MetS. This cross-sectional analysis involved 6633 men and women included in the PREDIMED (PREvención con DIeta MEDiterranea-Plus) study. The polyphenol content of foods was estimated from the Phenol-Explorer 3.6 database. The mean of total polyphenol intake was 846 ± 318 mg/day. Except for stilbenes, women had higher polyphenol intake than men. Total polyphenol intake was higher in older participants (>70 years of age) compared to their younger counterparts. Participants with body mass index (BMI) >35 kg/m2 reported lower total polyphenol, flavonoid, and stilbene intake than those with lower BMI. Total polyphenol intake was not associated with a better profile concerning MetS components, except for high-density lipoprotein cholesterol (HDL-c), although stilbenes, lignans, and other polyphenols showed an inverse association with blood pressure, fasting plasma glucose, and triglycerides. A direct association with HDL-c was found for all subclasses except lignans and phenolic acids. To conclude, in participants with MetS, higher intake of several polyphenol subclasses was associated with a better profile of MetS components, especially HDL-c.The PREDIMED-Plus trial was supported by official Spanish institutions for funding scientific biomedical research, CIBER Fisiopatología de la Obesidad y Nutrición (CIBERobn) and Instituto de Salud Carlos III (ISCIII), through the Fondo de Investigación para la Salud (FIS), which is co-funded by the European Regional Development Fund (four coordinated FIS projects led by J.S.-S. and J.Vi., including the following projects: PI13/00673, PI13/00492, PI13/00272, PI13/01123, PI13/00462, PI13/00233, PI13/02184, PI13/00728, PI13/01090, PI13/01056, PI14/01722, PI14/00636, PI14/00618, PI14/00696, PI14/01206, PI14/01919, PI14/00853, PI14/01374, PI14/00972, PI14/00728, PI14/01471, PI16/00473, PI16/00662, PI16/01873, PI16/01094, PI16/00501, PI16/00533, PI16/00381, PI16/00366, PI16/01522, PI16/01120, PI17/00764, PI17/01183, PI17/00855, PI17/01347, PI17/00525, PI17/01827, PI17/00532, PI17/00215, PI17/01441, PI17/00508, PI17/01732, and PI17/00926), the Special Action Project entitled: Implementación y evaluación de una intervención intensiva sobre la actividad física Cohorte PREDIMED-Plus grant to J.S.-S., the Recercaixa grant to J.S.-S.
