CD3+ T lymphocytes were present in the retina (11/18 cases), optic nerve (2/18 cases), and lacrimal gland (11/18 cases). No CD20+ B lymphocytes or Iba1+ macrophages were detected. PCR for rabies virus was positive in 9 of 11 frozen samples but in only 2 of 7 FFPE samples. Five samples that were negative for rabies by PCR were positive by immunohistochemistry, and 2 samples were negative by both tests. These results provide evidence that rabies virus infection extends to the eye, likely via the ocular nerve, and that the lacrimal gland might be a source of viral infection.Lymphoma is the most common intestinal neoplasm in horses, but its clinical-pathological features are poorly characterized. Primary intestinal lymphoma was diagnosed in 20 horses on biopsy samples and further confirmed by postmortem examination in 16 cases. Lymphoma was found in the small intestine in 12 of 20 (60%), in the colon in 5 of 20 (25%), and in both small and large intestines in 3 of 20 (15%) cases. Gross findings included thickening of the intestinal wall (45%), mural nodules or masses (30%), and both thickening and nodules (10%). Cases were classified according to the human World Health Organization classification as enteropathy-associated T-cell lymphoma (EATL) type 1 (40%), EATL type 2 (45%), and T-cell-rich large B-cell lymphoma (TCRLBCL) (15%). With respect to histologic grade, 70% of cases were grade 1 and 30% were grade 2. Of EATLs, the infiltrate was mucosal only (12%), mucosal and submucosal (53%), or transmural (35%). EATL1 was submucosal to transmural (2/8 and 6/8), EATL2 was mucosal to submucosal (3/9 and 6/9), and TCRLBCL was always transmural. Epitheliotropism was present in most EATLs and characterized by single-cell infiltrates within the epithelium in EATL1 and intraepithelial clusters or plaques in EATL2. Median survival was 25 days for EATL1, 90 days for EATL2, and 187.5 days for TCRLBCL; differences were not statistically significant. Of the EATLs, grade 1 had a median survival of 60 days and grade 2 had a median survival of 25 days; differences were not statistically significant.BACKGROUND Planning pregnancy in patients with active multiple sclerosis (MS) is highly challenging because treatment withdrawn may be associated with dramatic disease reactivation. OBJECTIVE To compare two strategies for women with active MS who were planning pregnancy stopping natalizumab (1) at the end of the first trimester and (2) at conception. METHODS Standardized strategy for women with active MS was initiated in our department. Maintenance of natalizumab until the end of first trimester was recommended (“secured first trimester” (SFT)). When patients refused, they were advised to continue until conception (“secured conception” (SC)). Predictors of disease activity during pregnancy were assessed. RESULTS Forty-six pregnancies were prospectively followed (30 with SFT and 16 with SC). One congenital anomaly occurred in the SC group. The proportions of patients with relapse and disability progression during pregnancy were lower in the SFT than in the SC group (3.6% vs 38.5%, p less then 0.005 and 3.6% vs 30.8%, p less then 0.05, respectively). Predictors of relapse and disability progression during pregnancy were the time when natalizumab was stopped (conception vs end of first trimester) and the number of relapses during the year before natalizumab. CONCLUSION Maintaining natalizumab during the first trimester may reduce the risk of disease reactivation during pregnancy in patients with active MS.This study was conducted to evaluate the performance of anammox reaction on the addition of iron. Iron was added in the form of FeSO4 starting with 2 mg/L (phase I), 5 mg/L (phase II), 8 mg/L (phase III), 10 mg/L (phase IV), 30 mg/L (phase V) and 50 mg/L (phase VI) on the addition of Fe (II) in anammox reactor. The efficiency of ammonia removal increased up to 90% with 5 mg/L of Fe (II) addition as compared to 77% when no Fe (II) was added. As the iron dosing was increased from 10 to 30 mg/L, ammonia removal declined sharply, which recovered slowly at steady-state condition. However, on the addition of 30 and 50 mg/L of Fe (II), the efficiency declined to 55% and 44%, respectively and did not recover. At 5 mg/L Fe (II) the nitrite removal was nearly 80% which declined to 44% at 50 mg/L. This was attributed to low pH values which hindered anammox activity. The mass balance study of nitrogen in the anammox process revealed that gas production was highest at 5 mg/L of Fe (II) conforming that 5 mg/L of Fe (II) is the optimum dose of iron for enhancing anammox reaction.Exposure to high and/or repetitive force exertions can lead to musculoskeletal injuries. However, measuring worker force exertion levels is challenging, and existing techniques can be intrusive, interfere with human-machine interface, and/or limited by subjectivity. In this work, computer vision techniques are developed to detect the force exertions using facial videos and wearable photoplethysmogram. Eighteen participants (19-24 years) performed isometric grip exertions at varying levels of maximum voluntary contraction. Novel features that predict forces were identified and extracted from video and photoplethysmogram data. Two experiments with two (High/Low) and three (0%MVC/50%MVC/100%MVC) labels were performed to classify exertions. The Deep Neural Network classifier performed the best with 96% and 87% accuracy for two- and three-level classifications. This approach was robust to leave subjects out during cross-validation (86% accuracy when 3-subjects were left out) and robust to noise (i.e., 89% accuracy for classifying talking activities as low force exertions).Practitioner Summary Forceful exertions are contributing factors to musculoskeletal injuries, yet it remains difficult to measure in work environments. This paper presents an approach to estimate force exertion levels, which is less distracting to workers, easier to implement by practitioners, and could potentially be used in wide variety of workplaces.Roughly 20% of women in the USA will seek an abortion during their lifetimes. As abortion is a medical procedure, individuals seeking abortion services must have access to accurate medical information. Selleckchem Auranofin Inaccurate information about abortion, known as abortion misinformation, adversely affects knowledge about abortion, and may impair informed decision-making. Abortion misinformation has received limited attention in psychological and health research. This review summarises current findings on abortion misinformation from studies of adults in the USA, examines which forms of misinformation are most common, and assesses prominent sources of abortion misinformation. A narrative, integrative approach was adopted focussing on nine articles. Findings suggest that first, inaccurate beliefs about abortion exist among many samples of US adults, including inaccurate connections between abortion and breast cancer, infertility and negative mental health outcomes. Second, abortion misinformation comes from a variety of informational sources, which may render efforts to prevent it challenging.
