Significant differences in the response rates and progression-free survival were observed between the sensitizing EGFR MF-high and sensitizing EGFR MF-low groups (cutoff median) at C4. In conclusion, ctDNA monitoring for sensitizing EGFR mutations at C4 is suitable for predicting the treatment outcomes in NSCLC patients receiving osimertinib (Clinical Trial Registration No. UMIN000022076).<br /><br /> Platelet-rich plasma (PRP) injections have been introduced to augment the recovery of patients with shoulder pathology. Although multiple studies have been published, no large-scale trials or meta-analyses have assessed the efficacy of nonoperative shoulder PRP injection.<br /><br /> To assess the efficacy of nonoperative PRP shoulder injection in rotator cuff pathology for pain as measured by the visual analog scale (VAS) and range of motion (ROM).<br /><br /> Two authors independently screened the Medline and Cochrane databases to include prospective studies that reported VAS and ROM outcomes for nonoperative shoulder PRP injections for rotator cuff pathology. Study quality was assessed using the revised Cochrane Collaboration risk-of-bias tool and modified Downs and Black checklist. Subsequent meta-analysis was performed to determine the effect of nonoperative PRP injections on pain and ROM 3 to 12 months after intervention.<br /><br /> Six studies met systematic review criteria. The included studies used different PRP formulations (to natural recovery or nonoperative PRP.<br /><br />There is a limited quantity of high-quality studies that assess the efficacy of nonoperative PRP shoulder injection for pain and ROM. Systematic review of PRP injections did not demonstrate an improvement in pain or ROM compared to physical therapy. Although within-group meta-analysis of nonoperative PRP statistically showed that nonoperative PRP improved pain, the lack of adequate negative controls precludes the ability to conclude whether improvements were due to natural recovery or nonoperative PRP.The ecology and structure of many tropical coral reefs have been markedly altered over the past few decades. Although long-term recovery has been observed in terms of coral cover, it is not clear how novel species configurations shape reef functionality in impaired reefs. The identities and life-history strategies of the corals species that recover are essential for understanding reef functional dynamics. We used a species identity approach to quantify the physical functionality outcomes over a 13 year period across 56 sites in the Mexican Caribbean. This region was affected by multiple stressors that converged and drastically damaged reefs in the early 2000s. Since then, the reefs have shown evidence of a modest recovery of coral cover. We used Bayesian linear models and annual rates of change to estimate temporal changes in physical functionality and coral cover. Moreover, a functional diversity framework was used to explore changes in coral composition and the traits of those assemblages. Between 2005 and 2018, physical functionality increased at a markedly lower rate compared to that of coral cover. The disparity between recovery rates depended on the identity of the species that increased (mainly non-framework and foliose-digitate corals). No changes in species dominance or functional trait composition were observed, whereas non-framework building corals consistently dominated most reefs. Although the observed recovery of coral cover and functional potential may provide some ecological benefits, the long-term effects on reef frameworks remain unclear, as changes in the cover of key reef-building species were not observed. Our findings are likely to be representative of many reefs across the wider Caribbean basin, as declines in coral cover and rapid increases in the relative abundance of weedy corals have been reported regionally. A coral identity approach to assess species turnover is needed to understand and quantify changes in the functionality of coral reefs.<br /><br /> β-Amyloid formation has been suggested to form part of the brain's response to bacterial infection. This hypothesis has been based on experimental animal studies and autopsy studies in humans. We asked if β-amyloid accumulates locally around a bacterial brain abscess in living human patients. Furthermore, because brain abscess patients may suffer from chronic cognitive symptoms after abscess treatment, we also asked if a brain abscess precipitates accumulation of β-amyloid in the neocortex in a manner that could explain abscess-related cognitive complaints.<br /><br /> In a prospective study, we investigated 17 brain abscess patients (age 24-72years) with <br /><br /> F-flutemetamol positron emission tomography on one occasion 1 to 10months after brain abscess treatment to visualize β-amyloid accumulation.<br /><br /> F-flutemetamol uptake was reduced in the edematous brain tissue that surrounded the abscess remains. On this background of reduced <br /><br /> F-flutemetamol signal, three out of 17 patients showed a distinctly increased <br /><br /> F-flutemetamol uptake in the tissue immediately surrounding the abscess remains, suggesting accumulation of β-amyloid. These three patients underwent <br /><br /> F-flutemetamol positron emission tomography significantly earlier after neurosurgical treatment (p=0.042), and they had larger abscesses (p=0.027) than the rest of the patients. All 17 patients suffered from mental fatigue or some subjective cognitive symptom, such as attention difficulties or memory problems, but in none of the patients was there an increase in neocortical <br /><br /> F-flutemetamol signal.<br /><br /> β-Amyloid may accumulate locally around the abscess remains in some patients with a brain abscess.<br /><br />β-Amyloid may accumulate locally around the abscess remains in some patients with a brain abscess.Donor-specific antibody (DSA) is an independent risk factor for antibody-mediated rejection (ABMR) and graft loss. The C1q assay differentiates complement from non-complement-binding DSA and C1q-binding DSA may lead to poor allograft survival. Our aim was to characterize the type of DSA seen in pediatric kidney transplant recipients and to determine whether complement binding DSA was associated with inferior graft survival.This was a single-center retrospective study of 48 children who were transplanted between 2009 and 2016. DSA were monitored using Luminex single antigen beads. A negative crossmatch was required to proceed with transplantation. The median follow-up time was 4.9 (3.4, 7.9) years. The median age was 12 (5.7, 15.4) years. DSA developed in 27/48 (56.3%), while C1q-binding DSA developed in 17/27 (63%). There were no significant differences between DSA negative, C1q-binding DSA, and C1q negative DSA, with regard to the number of HLA-ABDR (P = .09) or HLA-DQ mismatches alone (P = .16).
