- The DAWN and DEFUSE-3 trials showed the benefit of endovascular treatment (EVT) in acute ischemic stroke patients presenting beyond 6 hours from last known well (LKW) and selected by perfusion imaging criteria. The ESCAPE NA1-trial selected patients based on non-contrast CT (NCCT) Alberta Stroke Program Early CT Score (ASPECTS) and multiphase CT angiography (CTA) collateral status. This study compares baseline characteristics, workflow, and outcomes in the EVT arms of DAWN and DEFUSE-3 with late-window patients from the EVT-only arm of ESCAPE-NA1.MethodsAggregate data on baseline characteristics, workflow, reperfusion quality, final infarct volume, and clinical outcomes (modified Rankin Score [mRS] at 90 days) in subjects enrolled in the DAWN and DEFUSE-3 EVT arms were compared with similar data from the ESCAPE-NA1 control arm (EVT-only arm) presenting beyond 6 hours from LKW using descriptive statistics.ResultsBaseline characteristics among late-window patients in the ESCAPE NA1 trial were similar to those in the DAWN and DEFUSE-3 EVT arms. Median time from LKW-to-puncture in subjects enrolled in the ESCAPE NA1 trial was 9 hrs (IQR: 7.5–11 hours) when compared with DAWN (n=107; 12.8 hours, IQR: 10.6–16.7 hours) and DEFUSE-3 (n=92; 11.5 hours, IQR: 9.2–12.8 hours). Median post-treatment infarct-volume was largest in the ESCAPE NA1-patients (47 mL [IQR: 19–146] vs median 8 mL [IQR: 0–48] in the DAWN group and 35 mL [IQR: 18–82] in DEFUSE-3), while % mRS 0–2 at 90 days were similar across the three trials (ESCAPE NA1: 50/111 [45%], DAWN: 52/107 [49%], DEFUSE-3: 41/92 [45%]).ConclusionPatients enrolled beyond 6 hours from LKW in the ESCAPE-NA1 trial based on NCCT-ASPECTS and mCTA had similar clinical outcomes when compared with patients selected by perfusion imaging in the DAWN and DEFUSE-3 trials.

Effects of Parathyroidectomy on Quality of Life: 10 Years of Data From a Prospective Randomized Controlled Trial on Primary Hyperparathyroidism (the SIPH-Study)

- Primary hyperparathyroidism (PHPT) was previously considered a disease presenting with multiorgan involvement and a wide range of symptoms. Today, the disease presents with no symptoms or mild symptomatology in most patients. Data regarding nonspecific symptoms such as pain, fatigue, memory loss, depression, and other neuropsychiatric signs have been ambiguous, and results from prospective long-term randomized control trials are lacking. The Scandinavian Investigation on Primary Hyperparathyroidism (SIPH) is a prospective randomized controlled trial (RCT) with 10-year follow up, comparing parathyroidectomy (PTX) to observation without any treatment (OBS). From 1998 to 2005, 191 patients with mild PHPT were included from Sweden, Norway, and Denmark. A total of 95 patients were randomized to PTX and 96 to OBS. The generic Short Form-36 survey (SF-36) and the Comprehensive Psychopathological Rating Scale (CPRS) were studied at baseline, 2, 5, and 10 years after randomization. After 10 years, the PTX group scored significantly better on vitality (PTX 65.1 +/- 20.2 versus OBS 57.4 +/- 22.7; p = .017) compared to the OBS group in SF-36. We found no differences between the groups in the physical subscales. The OBS group had no significant change in any of the SF-36 scores throughout the study. The CPRS showed an improvement of symptoms in both groups for single items and sum scores after 10 years compared to baseline. There were, however, no significant differences between the two groups in the CPRS data. The results of this large and long-term RCT indicate improvement in some of the mental domains of SF-36 following PTX. However, the treatment effects between the groups were subtle with uncertain clinical significance. The observation group had stable SF-36 values and improvement in CPRS symptom-scores. Thus, in considering only quality of life (QoL) and in the absence of declines in renal and skeletal parameters, it may be safe to observe patients with mild PHPT for a decade.

Analyses of mads‐box genes suggest hvmads56 to regulate lateral spikelet development in barley

- MADS‐box transcription factors are crucial regulators of inflorescence and flower development in plants. Therefore, the recent interest in this family has received much attention in plant breeding programs due to their impact on plant development and inflorescence architecture. The aim of this study was to investigate the role of HvMADS‐box genes in lateral spikelet development in barley (Hordeum vulgare L.). A set of 30 spike‐contrasting barley lines were phenotypically and genotypically investigated under controlled conditions. We detected clear variations in the spike and spikelet development during the developmental stages among the tested lines. The lateral flo-rets in the deficiens and semi‐deficiens lines were more reduced than in two‐rowed cultivars except cv. Kristina. Interestingly, cv. Kristina, int‐h.43 and int‐i.39 exhibited the same behavior as def.5, def.6, semi‐def.1, semi‐def.8 regarding development and showed reduced lateral florets size. In HOR1555, HOR7191 and HOR7041, the lateral florets continued their development, eventually setting seeds. In contrast, lateral florets in two‐rowed barley stopped differentiating after the awn primordia stage giving rise to lateral floret sterility. At harvest, the lines tested showed large variation for all central and lateral spikelet‐related traits. Phylogenetic analysis showed that more than half of the 108 MADS‐box genes identified are highly conserved and are expressed in different barley tissues. Re-sequence analysis of a subset of these genes showed clear polymorphism in either SNPs or in/del. Variation in HvMADS56 correlated with altered lateral spikelet morphology. This suggests that HvMADS56 plays an important role in lateral spikelet development in barley.
