Background: Acute acoustic trauma (AAT) is an acute hearing impairment caused by intense noiseimpact. The current management strategy for AAT with substantial hearing loss in the Dutch militaryis the combination therapy with corticosteroids and hyperbaric oxygen therapy (HBOT). In a previousstudy, early initiation of the combination therapy was associated with better outcomes. Therefore, weperformed a new analysis to assess the difference in hearing outcome between patients in whomcombination therapy was started within two days, versus after more than two ***: A retrospective analysis was performed on military patients diagnosed with AAT with substantial hearing loss who presented between February 2018 and March 2020. Absolute and relativehearing improvement between first and last audiograms were calculated for all affected frequencies(defined as loss of 20 dB on initial audiogram). We also determined the amount of patients whorecovered to the level of Dutch military requirement, and performed speech discrimination ***: In this analysis, 30 male patients (49 ears) with AAT were included. The median age was 24.5years (IQr 23e29). The median time to initiation of therapy with corticosteroids and HBOT were one andtwo days, respectively. HBOT was started within two days in 31 ears, and after more than two days in 18ears. The mean absolute and relative hearing gains were 18.8 dB (SD 14.6) and 46.8% (SD 31.3) on allaffected frequencies. The 100% discrimination/speech perception level improved from 64.0 dB to 51.7 dB(gain 12.3 dB ± 14.1). There was significantly more improvement in absolute and relative hearingimprovement when HBOT was started in 2 days, compared to >2 ***: Our analysis shows results in favor of early initiation ( 2 days) of the combination treatmentof HBOT and corticosteroids in patients with AAT.

The location and the histological features of all colonic neoplasia were recorded. The prevalence and the distribution ofadvanced colorectal neoplasia and differences in yield between indication clusters were evaluated. Advanced neoplasm was defi ned as adenoma > 10 mm in size,with > 25% villous features or with high-grade dyspla-sia or ***:A total of 4623 eligible patients underwent a total colonoscopy. The prevalence of advanced neo-plasia was 13%,with 281 (6%) adenocarcinomas and 342 (7%) advanced adenomas. Sixty-seven percent and 33% of advanced neoplasia were located in the distal and proximal colon,respectively. Of all patients with right-sided advanced neoplasia (n = 228),51% had a normal distal colon,whereas 27% had a syn-chronous distal adenoma. Ten percent of all colono-scopies were performed in asymptomatic patients,7% of whom had advanced neoplasia. In the respective procedure indication clusters,the prevalence of right-sided advanced neoplasia ranged from 11%-57%. CONCLUSION:One out of every 7-8 colonoscopies yielded an advanced colorectal neoplasm. Colonoscopy is warranted for the evaluation of both symptomatic and asymptomatic patients.

元音和谐指在特定的语法范畴内,所有元音具有某个或某些共同的特征,比如腭位、唇状、舌位高低或舌根位置等(van der hulst 2016)。元音和谐是在阿尔泰语系、乌拉尔语系以及非洲诸语言中普遍存在的音系过程。元音和谐可以贯穿整个语素,也可以跨越语素界,绝大多数语言的元音和谐域是韵律词。根据和谐的方向,元音和谐可分为单向和谐和双向和谐。根据触发元音的特征,元音和谐可分为词根控制型和词缀控制型。元音和谐的复杂性主要体现在中性元音上。所谓中性元音,是指那些不参与和谐的元音。一直以来,中性元音被分为两大类:不透明性和透明性。不透明性中性元音会阻断和谐过程,而透明性中性元音允许和谐特征通过并进一步扩散(Archangeli and Pulleyblank 2007)。几十年以来,对中性元音的形式特征的描述一直是音系学研究中的难题。目前已有对中性元音作出有效而经济的解释的多种尝试,但无论是历时音变说、特征不充分赋值说,还是特征漂浮说等.

AIM: To improve the interpretation of fecal immunochemical test (FIT) results in colorectal cancer (CrC) cases from screening and referral cohorts. METHODS: In this comparative observational study, two prospective cohorts of CrC cases were compared. The first cohort was obtained from 10 322 average risk subjects invited for CrC screening with FIT, of which, only subjects with a positive FIT were referred for colonoscopy. The second cohort was obtained from 3637 subjects scheduled for elective colonoscopy with a positive FIT result. The same FIT and positivity threshold (OC sensor; ≥ 50 ng/mL) was used in both cohorts. Colonoscopy was performed in all referral subjects and in FIT positive screening subjects. All CrC cases were selected from both cohorts. Outcome measurements were mean FIT results and FIT scores per tissue tumor stage (T stage). rESULTS: One hundred and eighteen patients with CrC were included in the present study: 28 cases obtained from the screening cohort (64% male; mean age 65 years, SD 6.5) and 90 cases obtained from the referral cohort (58% male; mean age 69 years, SD 9.8). The mean FIT results found were higher in the referral cohort (829 ± 302 ng/mLvs 613 ± 368 ng/mL,P = 0.02). Tissue tumor stage (T stage) distribution was dif-ferent between both populations [screening population: 13 (46%) T1, eight (29%) T2, six (21%) T3, one (4%) T4 carcinoma; referral population: 12 (13%) T1, 22 (24%) T2, 52 (58%) T3, four (4%) T4 carcinoma], and higher T stage was significantly associated with higher FIT results (P r tumor stage, no significant difference in mean FIT results was observed (screening vs referral: T1 498 ± 382 ng/mL vs 725 ± 374 ng/mL, P = 0.22; T2 787 ± 303 ng/mL vs 794 ± 341 ng/mL, P = 0.79; T3 563 ± 368 ng/mLvs 870 ± 258 ng/mL,P = 0.13; T4 not available). After correction for T stage in logistic regression analysis, no significant differences in mean FIT results were observed between both types of cohorts (P = 0.10). CONCLUSION
