Risk of Esophageal Adenocarcinoma After Helicobacter pylori Eradication Treatment in a Population-Based Multinational Cohort Study.

BACKGROUND & AIMS: Helicobacter pylori infection is associated with a decreased risk of esophageal adenocarcinoma, and the decreasing prevalence of such infection might contribute to the increasing incidence of this tumor. We examined the hypothesis that eradication treatment of H pylori increases the risk of esophageal adenocarcinoma. METHODS: This population-based multinational cohort, entitled "Nordic Helicobacter Pylori Eradication Project (NordHePEP)," included all adults (≥18 years) receiving H pylori eradication treatment from 1995-2018 in any of the 5 Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden) with follow-up throughout 2019. Data came from national registers. We calculated standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) by dividing the cancer incidence in the exposed cohort by that of the entire Nordic background populations of the corresponding age, sex, calendar period, and country. Analyses were stratified by factors associated with esophageal adenocarcinoma (ie, education, comorbidity, gastroesophageal reflux, and certain medications). RESULTS: Among 661,987 participants who contributed 5,495,552 person-years after eradication treatment (median follow-up, 7.8 years; range, 1-24 years), 550 cases of esophageal adenocarcinoma developed. The overall SIR of esophageal adenocarcinoma was not increased (SIR = 0.89; 95% CI, 0.82-0.97). The SIR did not increase over time after eradication treatment, but rather decreased and was 0.73 (95% CI, 0.61-0.86) at 11-24 years after treatment. There were no major differences in the stratified analyses. The overall SIR of esophageal squamous cell carcinoma, calculated for comparison, showed no association (SIR = 0.99; 95% CI, 0.89-1.11). CONCLUSIONS: This absence on an increased risk of esophageal adenocarcinoma after eradication treatment of H pylori suggests eradication is safe from a cancer perspective.

Long-term results after primary intraocular lens implantation in children with juvenile idiopathic arthritis-associated uveitis.

PURPOSE: To evaluate the long-term outcome after cataract surgery with primary intraocular lens implantation in children with juvenile idiopathic arthritis-associated uveitis. METHODS: The medical records of all 24 children (34 eyes) with chronic juvenile idiopathic arthritis-associated uveitis who underwent cataract surgery between 1990 and 2013 were reviewed retrospectively. Primary intraocular lens implantation was performed in all patients. RESULTS: Median age at diagnosis of uveitis in the first eye was 5.3 years (range: 2.7-9.4 years) and median age at the time of cataract surgery in the first eye was 9.7 years (range: 4.1-16.9 years). Postoperative follow-up time ranged from 1 to 23.1 years, with a median of 10.9 years. Best corrected visual acuity at the last follow-up was good (⩾20/40) in 65% of the eyes. Postoperatively, glaucoma developed in 8 eyes (24%), posterior capsular opacification and secondary membrane formation requiring surgery in 15 eyes (44%), macular oedema in 5 eyes (15%) and phthisis in 2 eyes (6%). CONCLUSION: This study shows a favourable visual outcome in most of the cases. Primary intraocular lens implantation may be considered in juvenile idiopathic arthritis-associated uveitis complicated by cataract in patients with well-controlled inflammation.

Processing Relative Clause Extractions in Swedish.

Relative clauses are considered strong islands for extraction across languages. Swedish comprises a well-known exception, allegedly allowing extraction from relative clauses (RCE), raising the possibility that island constraints may be subject to "deep variation" between languages. One alternative is that such exceptions are only illusory and represent "surface variation" attributable to independently motivated syntactic properties. Yet, to date, no surface account has proven tenable for Swedish RCEs. The present study uses eyetracking while reading to test whether the apparent acceptability of Swedish RCEs has any processing correlates at the point of filler integration compared to uncontroversial strong island violations. Experiment 1 tests RCE against licit that-clause extraction (TCE), illicit extraction from a non-restrictive relative clause (NRCE), and an intransitive control. For this, RCE was found to pattern similarly to TCE at the point of integration in early measures, but between TCE and NRCE in total durations. Experiment 2 uses RCE and extraction from a subject NP island (SRCE) to test the hypothesis that only non-islands will show effects of implausible filler-verb dependencies. RCE showed sensitivity to the plausibility manipulation across measures at the first potential point of filler integration, whereas such effects were limited to late measures for SRCE. In addition, structural facilitation was seen across measures for RCE relative to SRCE. We propose that our results are compatible with RCEs being licit weak island extractions in Swedish, and that the overall picture speaks in favor of a surface rather than a deep variation approach to the lack of island effects in Swedish RCEs.

Acute exudative polymorphous vitelliform maculopathy in a young woman: presymptomatic findings and 21-month follow-up.

PURPOSE: To describe ocular findings before and after the diagnosis of acute exudative polymorphous vitelliform maculopathy, in an otherwise healthy 28-year-old woman. METHODS: Case report with 21-months of follow-up. Fundus photography, optical coherence tomography, fluorescein angiography, indocyanine green angiography, and autofluorescence were used for imaging the retina. To examine retinal function, full-field electroretinogram, multifocal electroretinogram, electrooculography, and dark adaptometry were performed. Genetic analysis for mutations associated with Best disease was done. RESULTS: In the asymptomatic patient before diagnosis, white-yellow, drusen-like, subretinal depositions were found in both eyes. A few months later, the patient developed bilateral visual disturbances. Retinal examination at the acute phase revealed a characteristic pattern of multifocal white-yellow subretinal lesions in both posterior poles, imaged by ophthalmoscopy, fluorescein angiography, indocyanine green angiography, and optical coherence tomography. Additionally, electrooculography and dark adaptometry were abnormal. Full-field electroretinogram was normal, but multifocal electroretinogram revealed central depression of peak amplitudes. During the 21-month follow-up without any treatment, visual acuity recovered, electrooculography and dark adaptometry normalized, and the patient experienced one episode of relapse. Genetic studies excluded mutations in the bestrophin gene (BEST1). CONCLUSION: Acute exudative polymorphous vitelliform maculopathy is still a condition of unknown origin, primarily affecting the pigment epithelium. Earlier reports have discussed whether the condition is inherited or acquired. In this report, the presymptomatic retinal findings in acute exudative polymorphous vitelliform maculopathy are described for the first time, indicating that a condition may be associated with primarily affected retinal pigment epithelium.

The influence of prognostic factors on neck pain intensity, disability, anxiety and depression over a 2-year period in subjects with acute whiplash injury.

The influence of potential prognostic factors (occupant- and crash-related factors, initial neck pain intensity and headache, whiplash injury severity, helplessness, locus of control, socioeconomic status) on neck pain intensity (VAS), disability (DRI), anxiety and depression (HADS) was estimated in a cohort of 3704 subjects with whiplash injury following a motor vehicle crash. Questionnaires were administered (baseline, 1-, 6-, 12-, 24-month follow-ups). VAS was trichotomized; "low" (0-30), "moderate" (31-54), "severe" (55-100). A cumulative logit model with a proportional odds assumption was applied. Results regarding depression differed somewhat from the other outcomes. Overall, initial neck pain intensity was an important prognostic factor, but acted also as an evident effect modifier. Females had slightly increased odds for all outcomes but depression, for which no gender differences were shown. Injury severity was associated with all outcomes, but was most pronounced regarding disability among those who perceived numbness/pain in arms/hands and also had severe initial neck pain (proportional odds ratio [OR] 6.5; 95% confidence interval [CI] 2.5-17.0). Initial headache influenced all outcomes. Income was not related to any of the outcomes, whereas a lower level of education was associated with all outcomes but depression. Locus of control was not a factor of importance. In contrast, helplessness was related to all outcomes, but was most pronounced regarding neck pain intensity and depression for subjects with severe initial neck pain (OR 4.8; 95% CI 2.9-7.8; OR 6.6; 95% CI 2.6-17.0). Associations seem to be established early, and then to be relatively constant over time.
