简介：AbstractObjective:To determine the incidence of preeclampsia (PE) and preterm PE in Spain and to identify the risk factors for developing the disease.Methods:This is a multicenter prospective cohort study performed at six maternity units across Spain. Women with singleton pregnancies attending their first-trimester routine visit at the hospital were offered participation. Maternal and pregnancy characteristics, including mean arterial pressure, as well as ultrasound findings were recorded. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for subsequent development of PE.Results:A total of 5868 pregnancies were recruited for this study, including 174 (3.0%) cases of PE, 47 (0.8%) cases of preterm PE and 127 (2.2%) cases of term PE. Median maternal age was 33.9 years (interquartile range: 30.1 to 36.9) and median gestational age at the routine visit was 12.7 weeks (interquartile range: 12.3 to 13.0). However, 293 (5.0%) of the women were on aspirin treatment during pregnancy, likely reducing the true incidence of the disease. As expected, increasing body mass index (P < 0.001), uterine artery pulsatility index (P= 0.011) and mean arterial pressure (P < 0.001), assisted conception (P= 0.013), previous personal (P < 0.001) or family history of PE (P= 0.024) and chronic hypertension (P= 0.001) were identified as independent risk factors for developing subsequent PE during pregnancy. Screening for PE by maternal factors alone leads to a detection rate of 36.8% (64/174) at 10.0% (587/5868) screen positive rate.Conclusion:In Spain, 3.0% of singleton pregnancies are complicated by PE and 0.8% require delivery before term due to its severity. Screening of PE by risk factors alone is only able to detect about 40% of total PE at 10% screen-positive rate.

简介：AbstractThroughout the past 2020, the pandemic COVID-19 has caused a big global shock, meanwhile it brought a great impact on the public health network. Trauma emergency system faced a giant challenge and how to manage trauma under the pandemic of COVID-19 was widely discussed. However, the trauma treatment of special population (geriatric patients and patients taking anticoagulant drugs) has received inadequate attention. Due to the high mortality following severe traumatic hemorrhage, hemostasis and trauma-induced coagulopathy are the important concerns in trauma treatment. Sepsis is another topic should not be ignored when we talking about trauma. COVID-19 itself is a special kind of sepsis, and it may even be called as serious systemic infection syndrome. Sepsis has been become a serious problem waiting to be solved urgently no matter in the fields of trauma, or in intensive care and infection, etc. This article reviewed the research progress in areas including trauma emergency care, trauma bleeding and coagulation, geriatric trauma and basic research of trauma within 2020.

简介：AbstractObjectives:Describe the h index as a bibliometric that can be utilized to objectively evaluate scholarly impact. Identify which otolaryngology subspecialties are the most scholarly. Describe if NIH funding to one’s choice of medical school, residency, or fellowship has any impact on one’s scholarly output. Determine other factors predictive of an academic otolaryngologist’s productivity.Study design:Analysis of bibliometric data of academic otolaryngologists.Methods:Active grants from the National Institutes of Health (NIH) to otolaryngology departments were ascertained via the NIH Research Portfolio Online Reporting Tools Expenditures and Reports database. Faculty listings from these departments were gleaned from departmental websites. H index was calculated using the Scopus database.Results:Forty-seven otolaryngology programs were actively receiving NIH funding. There were 838 faculty members from those departments who had a mean h index of 9.61. Otology (h index 12.50) and head and neck (h index 11.96) were significantly (P < 0.0001) more scholarly than the rest of subspecialists. H index was significantly correlative (P < 0.0001) with degree of NIH funding at a given institution. H index was not significantly higher for those that attended medical school (P < 0.18), residency (P < 0.16), and fellowship (P < 0.16) at institutions with NIH funding to otolaryngology departments.Conclusions:H index is a bibliometric that can be used to assess scholarly impact. Otology and head and neck are the most scholarly subspecialists within otolaryngology. NIH funding to an individual’s medical school, residency, or fellowship of origin is not correlative with one’s scholarly impact, but current institutional affiliation and choice of subspecialty are.

简介：AbstractObjective:Scoping review of published literature to establish clinical characteristics and audiologic outcomes in patients diagnosed with Susac’s Syndrome(SS) who have undergone cochlear implantation (CI).Data sources:All published studies of CI in SS and contribution of two of our own patients who have not been reported previously.Methods:A comprehensive search of MEDLINE (via PubMed) was carried out in March 2020 using the following keywords and related entry terms: Susac’s Syndrome, Cochlear Implantation. Results: Our search identified a total of five case reports of CI in SS. With the addition of our two patients reported here, we analyzed characteristics and outcomes in seven patients. Mean age at implantation was 30 years old (range 19-46), with six women and one man implanted. Mean time from onset of hearing loss to implantation was 17 months (range three months to four years). Best reported postoperative speech understanding was reported via different metrics, with six of seven patients achieving open set speech scores of 90% or better, and one subject performing at 68%. Vestibular symptoms were present preoperatively in four of seven patients (57%), with vestibular testing reported in two patients, and showing vestibulopathy in one patient. No complications were reported following cochlear implantation.Conclusion:Cochlear implantation is a viable option for hearing rehabilitation in patients with SS, with levels of attainment of open set speech comparable to other populations of CI candidates.
