Assessing the health effects as a result of PM2.5 as well as ozone smog within 338 Chinese cities from 2015 to be able to 2020.
The project led to proposed changes in clinical care and center infrastructure at each participating site. CONCLUSIONS A collaborative learning design fostered rapid dissemination, comparison, and sharing of strategies to approach a complex multidisciplinary care paradigm. L-Glutamic acid monosodium chemical structure Our assessment of experiences revealed marked variability across and within centers. The collaborative findings were a first step toward strategies to quantify and measure developmental care practices in the cardiac intensive care unit to assess the association of complex inpatient practices with long-term neurodevelopmental outcomes. OBJECTIVE To prospectively evaluate symptom outcomes after youth soccer-related concussion. STUDY DESIGN Using a prospective cohort design, we enrolled male and female competitive soccer players age 8-17 years into 3 groups concussed (n = 23), matched control (n = 23), and orthopedic injury (n = 24). Postconcussive symptoms were monitored serially via both athlete and parent report at days 1-2, 4, 7, 10, 30, and 90. RESULTS Repeated-measures analyses revealed a significant time by group interaction (F [12, 402] = 19.91, P less then .001). In the initial days postinjury, the concussed group reported greater symptoms than the comparison groups, with more symptoms reported by athletes on average than parents. By 10 days, concussed athletes did not differ from the matched controls by either rater's report, but they did differ from the orthopedic injury group by parent report. At 30 days, no differences were apparent among groups. At 30 days, 100% of concussed youth and 91% of parents rated symptoms as back to preinjury levels using reliable change indices. At 30 days, 86% of athletes had been cleared to return to full game play. CONCLUSIONS The natural clinical history of concussion symptoms in youth competitive soccer players was similar to that seen in older athletes, with resolution in days to a few weeks. Additional study will be required to investigate which factors best predict symptom outcomes for individual athletes and how symptom report relates to performance-based outcome measures and underlying neurophysiologic recovery. OBJECTIVE To examine the implementation and utilization of a pediatric acute stroke protocol over a 7-year period, hypothesizing improvements in protocol implementation and increased protocol use over time. STUDY DESIGN Clinical and demographic data for this retrospective observational study from 2011 through 2018 were obtained from a quality improvement database and medical records of children for whom the acute stroke protocol was activated. The initial 43 months of the protocol (period 1) were compared with the subsequent 43 months (period 2). RESULTS Over the 7-year period, a total of 385 stroke alerts were activated, in 150 children (39%) in period 1 and 235 (61%) in period 2, representing a 56% increase in protocol activation. Stroke was the final diagnosis in 80 children overall (21%), including 38 (25%) in period 1 and 42 (19%) in period 2 (P = .078). The combined frequency of diagnosed stroke, transient ischemic attack (TIA), and other neurologic emergencies remained stable across the 2 time periods at 39% and 37%, respectively (P = .745). Pediatric National Institutes of Health Stroke Scale (PedNIHSS) documentation increased from 42% in period 1 to 82% in period 2 (P less then .001). Magnetic resonance imaging (MRI) was the first neuroimaging study for 68% of the children in period 1 vs 78% in period 2 (P = .038). All children with acute stroke received immediate supportive care. CONCLUSIONS Pediatric stroke protocol implementation improved over time with increased use of the PedNIHSS and use of MRI as the first imaging study. However, with increased utilization, the frequency of confirmed strokes and other neurologic emergencies remained stable. The frequency of stroke and other neurologic emergencies in these children affirms the importance of implementing and maintaining a pediatric acute stroke protocol. PURPOSE To describe and analyze clinical findings in a patient with recurrent idiopathic acute exudative polymorphous vitelliform maculopathy (AEPVM), followed in detail, and to propose the diagnostic and follow-up algorithm. DESIGN Retrospective observational analysis. PATIENT A young adult male patient diagnosed with idiopathic AEPVM who developed two relapses in a 12-month period eight years after the initial onset. METHODS Review of clinical charts, multimodal imaging, and electrophysiology findings. The patient repeatedly underwent complete ophthalmic examinations, including best-corrected visual acuity testing (BCVA), slit-lamp and fundus examinations; digital fundus photography, time-domain optical coherence tomography (OCT) in 2009 (Stratus OCT, Carl Zeiss Meditec, USA) and spectral-domain OCT in 2017-2018 (Spectralis-OCT, Heidelberg Engineering, Germany), together with fundus autofluorescence (FAF), fluorescein angiography (FA), and indocyanine green angiography (ICGA), all with HRA2 (Heidelberg Engi-OCT were the most informative diagnostic methods, demonstrating the evolution of pathological signs. CONCLUSION AEPVM may be a recurrent or even chronic condition with uncertain long-term visual outcomes. It may have variable clinical presentations depending on the stage of the disease, and both clinical manifestations and imaging features of different stages of the pathologic process may overlap. Patients should be made aware that visual improvement occurs very slowly, if at all. Bimonthly fundus autofluorescence evaluation together with SD-OCT should be recommended in such cases. BACKGROUND Interleukin 12 (IL-12) is a pivotal regulator of innate and adaptive immunity. We conducted a prospective open-label, phase II clinical trial of electroporated plasmid IL-12 in advanced melanoma patients (NCT01502293). PATIENTS AND METHODS Patients with stage III/IV melanoma were treated intratumorally with plasmid encoding IL-12 (tavokinogene telseplasmid; tavo), 0.5 mg/ml followed by electroporation (six pulses, 1500 V/cm) on days 1, 5, and 8 every 90 days in the main study and additional patients were treated in two alternative schedule exploration cohorts. Correlative analyses for programmed death-ligand 1 (PD-L1), flow cytometry to assess changes in immune cell subsets, and analysis of immune-related gene expression were carried out on pre- and post-treatment samples from study patients, as well as from additional patients treated during exploration of additional dosing schedules beyond the pre-specified protocol dosing schedule. Response was measured by study-specific criteria to maximize detection of latent and potentially transient immune responses in patients with multiple skin lesions and toxicities were graded by the Common Terminology Criteria for Adverse Events version 4.
