Purpose: A direct aspiration, first pass technique (ADAPT) has been introduced as a rapid and safe thrombectomy strategy in patients with intracranial large vessel occlusion (LVO). The aim of the study is to determine the technical feasibility, safety, and functional outcome of ADAPT using the newly released large bore pHLO 0.072-inch aspiration catheter (AC; Phenox).Materials and Methods: We performed a retrospective analysis of data collected prospectively (October 2019–November 2021) from 2 comprehensive stroke centers. Accessibility of the thrombus, vascular recanalization, time to recanalization, and procedure-related complications were evaluated. National Institutes of Health stroke scale scores at presentation and discharge and the modified Rankin scale (mRS) score at 90 days post-procedure were recorded.Results: Twenty-five patients (14 female, 11 male) with occlusions of the anterior circulation were treated. In 84% of cases, ADAPT led to successful recanalization with a median procedure time of 28 minutes. In the remaining cases, successful recanalization required (to a total of 96%; modified thrombolysis in cerebral infarction score 2b/3) the use of stent retrievers. No AC-related complications were reported. Other complications included distal migration of the thrombus, requiring a stent-retriever, and symptomatic PH2 hemorrhage in 16% and 4%, respectively. After 3 months, 52% of the patients had mRS scores of 0–2 with an overall mortality rate of 20%.Conclusion: Results from our retrospective case series revealed that thrombectomy of LVOs with pHLO AC is safe and effective in cases of large-vessel ischemic stroke. Rates of complete or near-complete recanalization after the first pass with this method might be used as a new benchmark in future trials.

Background: The poultry industry suffers losses from problems as pale, soft and exudative (PSE), and dark, firm and dry (DFD) meat can develop in meat as a result of short- and long-term stress, respectively. These abnormalities are impacted by pre-slaughter animal welfare. Methods: This work evaluated the effects of open vehicle container microclimate, throughout the 38 ± 10 km journey from the farm to the slaughterhouse, on commercially turkey transported during the Brazilian winter season. The journey was initiated immediately after water bath in truck fitted with portable Kestrel anemometers to measure air ventilation, relative humidity, temperature and ventilation. Results: The inferior compartments of the middle and rear truck regions showed highest temperature and relative humidity, and lower air ventilation. In addition, the superior compartments of the front truck regions presented lower temperature and wind chill, and highest air ventilation. The breast meat samples from animals located at the inferior compartments of the middle and rear truck regions and subjected to with water bath (WiB) treatment presented highest DFD-like and had lowest PSE-like meat incidence than those from animals located at other compartments within the container. Lower incidence of PSE-like meat was observed in birds without water bath (WoB). Conclusions: Assessment on turkeys transported under Brazilian southern winter conditions revealed that breast meat quality can be affected by relative humidity, air ventilation, temperature, and transport under subtropical conditions promoting color abnormalities and the formation of simultaneously PSE-like and DFD-like meat.

The hybrid manufacturing procedure of combining an initial machining process and a posterior laser powder bed fusion (LPBF) process opens a new range of possibilities for manufacturing complex parts, promising to reduce both costs and printing time. Hence, the first portion of the part might be manufactured by machining, which is used as the substrate for the LPBF. Different manufacturing processes produce a melting interface zone (MIZ) that can affect the mechanical properties of hybrid parts. This work investigates the properties of the MIZ in hybrid parts. The influence of the energy density of the LPBF process on the interface zone and the mechanical properties of the final hybrid part were assessed. The different tests showed high-quality interphase even with low energy density, with a melting depth of up to 0.3 mm. Tomography analysis showed no pores in the MIZ and the increase in pore number with the scanning speed, reducing the UTS of the hybrid samples from 8 to 42% in relation to machined Corrax®. Additionally, a test piece for injection molding was produced by this new hybrid manufacturing process. The results showed that the costs and manufacturing time were reduced by about 50%, showing a potential application of hybrid manufacturing in such applications. Besides, this work identifies a limitation of the hybrid manufacturing approach using LPBF machines which are not equipped with a system to identify the substrate coordinate system. The present study develops an operational method to identify the coordinate system in order to ease the referencing of the pre-machined substrate within the machine platform.
