Filter by:In its 2012's release guideline on therapy for schizophrenia, the EMA joined the FDA to acknowledge primary and persistent negative symptoms (PNS) as an unmet need in the treatment of schizophrenia. Functional brain imaging studies showed a correlation between NS and reduced perfusion in the left dorsolateral prefrontal cortex (L-DLPFC). Pre-frontal activation (PFA) using repetitive transcranial magnetic stimulation (rTMS) significantly improve PNS (meta-analyses: effect size SMD = 0.55, ΔPANSS-N = -2.5). Yet schizophrenia is likely to gather many different natural entities of distinct pathophysiological mechanisms. Pursuing a one-size-fits-all approach will not adapt to this diversity and might account for inconsistencies in the results. Progressive periodic catatonia (PPC) is a rare psychotic phenotype (0.1 - 0.5 ‰) which has been shown to be longitudinally stable (30-years follow-up) and consistent within families (about 1 third of first-degree relatives are affected). The core of this phenotype is a disintegration of psychomotor processes which progresses with each relapse, resulting in a "deficit state", i.e., PNS, responsible for most social and occupational disabilities. The investigators and others reported PPC to come with hyper-perfusions in premotor cortices compared to controls or non-PPC chronic psychoses (nPPC). These hyper-perfusions discriminate PPC from nPPC or depressive patients (Sensitivity = 82%; Specificity = 95%). Last, in independent proof-of-principle studies the investigators and others have shown that premotor inhibition (PMI) using rTMS significantly improved PNS in PPC and that the most dramatic improvements followed personalized accelerated rTMS protocols (5 days of rTMS; CGI-improvement = 2 which is equivalent to ΔPANSS-N = -10; lasting > 1 month - vs virtually no change for PFA). The efficacy index was very good (no side effects). the investigators hypothesize that: (1) in PPC, add-on personalized premotor inhibition (PMI) is more effective in reducing PNS than L-DLPFC activation (PFA); (2) patient stratification is relevant as personalized PMI will not be as effective in the nPPC group (even expected to be less effective than PFA).
The many complaints that have been expressed by the US aircrew of the F-35 regarding the heat stress in the cockpit raised an obvious concern that, as a result of such heat levels, the aviators' core body temperature may increase significantly, and subsequently cause severe cognitive impairment- risking both the pilot and the mission. In order to validate this hypothesis, we will measure the aviators' core body temperatures while inside the cockpit of the F-35, to see whether their core body temperatures are rising to a level that can cause heat stress or not. The temperatures will be measured on another fourth generation aircraft as well for comparing purposes. The temperatures will be measured using a Telemetric pill which will be ingested by each aviator. Once ingested, the pill will transmit the data to an external monitor. The collected data will be examined and analyzed in order to determine the likelihood of heat stress occurrence.
Aim of this study was to evaluate the hypoxic response during hypobaric flight simulation in normal individuals as well as in normocapnic and hypercapnic COPD patients as well as to evaluate the impact of a flight simulation on walking endurance in these patients.
