TL;DR: A new set of criteria for IBP performed better than previous criteria in AS patients with established disease and a prospective study is needed to validate the diagnostic properties of the new candidate criteria set in patients with early disease.
Abstract: Objective
Back pain associated with ankylosing spondylitis (AS) is referred to as inflammatory back pain (IBP). The value of the clinical history in differentiating IBP from mechanical low back pain (MLBP) has been investigated in only a few studies. In this exploratory study, we sought to evaluate the individual features of IBP and to compose and compare various combinations of features for use as classification and diagnostic criteria.
Methods
We assessed the clinical history of 213 patients (101 with AS and 112 with MLBP) younger than 50 years who had chronic back pain. Single clinical parameters and combinations of parameters were compared between the AS and MLBP patient groups.
Results
Morning stiffness of >30 minutes' duration, age at onset of back pain, no improvement in back pain with rest, awakening because of back pain during the second half of the night only, alternating buttock pain, and time period of the onset of back pain were identified as independent contributors to IBP. Importantly, none of the single parameters sufficiently differentiated AS from MLBP. In contrast, several sets of combined parameters proved to be well balanced between sensitivity and specificity. Among these, a new candidate set of criteria for IBP, which consisted of morning stiffness of >30 minutes' duration, improvement in back pain with exercise but not with rest, awakening because of back pain during the second half of the night only, and alternating buttock pain, yielded a sensitivity of 70.3% and a specificity of 81.2% if at least 2 of these 4 parameters were fulfilled (positive likelihood ratio 3.7). If at least 3 of the 4 parameters were fulfilled, the positive likelihood ratio increased to 12.4.
Conclusion
A new set of criteria for IBP performed better than previous criteria in AS patients with established disease. A prospective study is needed to validate the diagnostic properties of the new candidate criteria set in patients with early disease.

TL;DR: The use of very low VT ventilation combined with extracorporeal CO2 removal has the potential to further reduce VILI compared with a ‘normal’ lung protective management.
Abstract: Acute respiratory distress syndrome is characterized by damage to the lung caused by various insults, including ventilation itself, and tidal hyperinflation can lead to ventilator induced lung injury (VILI). We investigated the effects of a low tidal volume (V
T) strategy (V
T ≈ 3 ml/kg/predicted body weight [PBW]) using pumpless extracorporeal lung assist in established ARDS. Seventy-nine patients were enrolled after a ‘stabilization period’ (24 h with optimized therapy and high PEEP). They were randomly assigned to receive a low V
T ventilation (≈3 ml/kg) combined with extracorporeal CO2 elimination, or to a ARDSNet strategy (≈6 ml/kg) without the extracorporeal device. The primary outcome was the 28-days and 60-days ventilator-free days (VFD). Secondary outcome parameters were respiratory mechanics, gas exchange, analgesic/sedation use, complications and hospital mortality. Ventilation with very low V
T’s was easy to implement with extracorporeal CO2-removal. VFD’s within 60 days were not different between the study group (33.2 ± 20) and the control group (29.2 ± 21, p = 0.469), but in more hypoxemic patients (PaO2/FIO2 ≤150) a post hoc analysis demonstrated significant improved VFD-60 in study patients (40.9 ± 12.8) compared to control (28.2 ± 16.4, p = 0.033). The mortality rate was low (16.5 %) and did not differ between groups. The use of very low V
T combined with extracorporeal CO2 removal has the potential to further reduce VILI compared with a ‘normal’ lung protective management. Whether this strategy will improve survival in ARDS patients remains to be determined (Clinical trials NCT 00538928).

TL;DR: The results of IMvigor130 support the use of atezolizumab plus platinum-based chemotherapy as a potential first-line treatment option for metastatic urothelial carcinoma and the safety profile of the combination was consistent with that observed with the individual agents.

TL;DR: In the striatum, a part of the basal ganglia affected in humans with a speech deficit due to a nonfunctional FOXP2 allele, it is found that medium spiny neurons have increased dendrite lengths and increased synaptic plasticity, suggesting that alterations in cortico-basal ganglia circuits might have been important for the evolution of speech and language in humans.
