Study of parafunctions in patients with chronic daily headache.

The purpose of this paper is to present the results of a questionnaire investigating parafunctions (particularly clenching and grinding). The questionnaire was elaborated by the Dental Clinic of the University of Milano and completed by 125 patients experiencing chronic daily headache and attending the Neurological Institute Carlo Besta for an inpatient withdrawal protocol to treat medication overuse related to chronic headaches. Our results showed high percentages of parafunctions, which were present in 80% of patients with chronic daily headache. We noted that patient information on possible behaviours and coexisting conditions which may be involved in the mechanisms of chronic headaches, as well as education about these factors, are crucial aspects in the management of chronic headache patients. It is important for clinicians to perform a thorough evaluation (based upon history taking and clinical examination) aimed at identifying parafunctions. Several studies showed that cranio-mandibular dysfunction (CMD) is prevalent in different headache forms, such as tension-type headache and migraine, and may have a role in their chronification. Overall, our data encourage the early diagnosis and treatment of muscular and mechanical aspects of CMD. All the diagnostic and therapeutic proposals over the years suggested that converting a dysfunctional stomatognathic system into a physiological and functional one is an appropriate and effective approach to the treatment of headaches. The achievement of a good muscular activity during clenching and a low activity at rest represent the main goals of our therapy. We suggest that patients suffering from chronic headaches are be evaluated as far as the need for interocclusal devices (as pointed out in previous studies of our group) is concerned, and in relation to the possible presence of parafunctions: their analysis, correction and prevention will ultimately limit their role as trigger factors or as coexisting conditions influencing the development/maintaining of headache chronification

Time course of risk factors associated with mortality of 1260 critically ill patients with COVID-19 admitted to 24 Italian intensive care units

94noopenPurpose: To evaluate the daily values and trends over time of relevant clinical, ventilatory and laboratory parameters during the intensive care unit (ICU) stay and their association with outcome in critically ill patients with coronavirus disease 19 (COVID-19). Methods: In this retrospective–prospective multicentric study, we enrolled COVID-19 patients admitted to Italian ICUs from February 22 to May 31, 2020. Clinical data were daily recorded. The time course of 18 clinical parameters was evaluated by a polynomial maximum likelihood multilevel linear regression model, while a full joint modeling was fit to study the association with ICU outcome. Results: 1260 consecutive critically ill patients with COVID-19 admitted in 24 ICUs were enrolled. 78% were male with a median age of 63 [55–69] years. At ICU admission, the median ratio of arterial oxygen partial pressure to fractional inspired oxygen (PaO2/FiO2) was 122 [89–175] mmHg. 79% of patients underwent invasive mechanical ventilation. The overall mortality was 34%. Both the daily values and trends of respiratory system compliance, PaO2/FiO2, driving pressure, arterial carbon dioxide partial pressure, creatinine, C-reactive protein, ferritin, neutrophil, neutrophil–lymphocyte ratio, and platelets were associated with survival, while for lactate, pH, bilirubin, lymphocyte, and urea only the daily values were associated with survival. The trends of PaO2/FiO2, respiratory system compliance, driving pressure, creatinine, ferritin, and C-reactive protein showed a higher association with survival compared to the daily values. Conclusion: Daily values or trends over time of parameters associated with acute organ dysfunction, acid–base derangement, coagulation impairment, or systemic inflammation were associated with patient survival.openZanella A.; Florio G.; Antonelli M.; Bellani G.; Berselli A.; Bove T.; Cabrini L.; Carlesso E.; Castelli G.P.; Cecconi M.; Citerio G.; Coloretti I.; Corti D.; Dalla Corte F.; De Robertis E.; Foti G.; Fumagalli R.; Girardis M.; Giudici R.; Guiotto L.; Langer T.; Mirabella L.; Pasero D.; Protti A.; Ranieri M.V.; Rona R.; Scudeller L.; Severgnini P.; Spadaro S.; Stocchetti N.; Vigano M.; Pesenti A.; Grasselli G.; Aspesi M.; Baccanelli F.; Bassi F.; Bet A.; Biagioni E.; Biondo A.; Bonenti C.; Bottino N.; Brazzi L.; Buquicchio I.; Busani S.; Calini A.; Calligaro P.; Cantatore L.P.; Carelli S.; Carsetti A.; Cavallini S.; Cimicchi G.; Coppadoro A.; Dall'Ara L.; Di Gravio V.; Erba M.; Evasi G.; Facchini A.; Fanelli V.; Feliciotti G.; Fusarini C.F.; Ferraro G.; Gagliardi G.; Garberi R.; Gay H.; Giacche L.; Grieco D.; Guzzardella A.; Longhini F.; Manzan A.; Maraggia D.; Milani A.; Mischi A.; Montalto C.; Mormina S.; Noseda V.; Paleari C.; Pedeferri M.; Pezzi A.; Pizzilli G.; Pozzi M.; Properzi P.; Rauseo M.; Russotto V.; Saccarelli L.; Servillo G.; Spano S.; Tagliabue P.; Tonetti T.; Tullo L.; Vetrugno L.; Vivona L.; Volta C.A.; Zambelli V.; Zanoni A.Zanella, A.; Florio, G.; Antonelli, M.; Bellani, G.; Berselli, A.; Bove, T.; Cabrini, L.; Carlesso, E.; Castelli, G.

Dynamics of selenium cycling in deciduous forests

International audienceSelenium is a trace element with major environmental implications, due to the extremely narrow range between its essential and toxic concentrations. Furthermore, the significant inventory of 79Se within high level radioactive waste coupled with its long physical half-life makes the study of stable Se behavior (as a surrogate of 79Se) important for our understanding of the long-term safety of any radioactive waste repository
