A new test for exemplar theory: Varying versus non-varying words in Spanish
We used a Deese-Roediger-McDermott false memory paradigm to compare Spanish words in which the phonetic realization of /s/ can vary (word-medial positions: bu[s]to ~ bu[h]to āchestā, word-final positions: remo[s] ~ remo[h] āoarsā) to words in which it cannot (word-initial positions: [s]opa ~ *[h]opa āsoupā). At study, participants listened to lists of nine words that were phonological neighbors of an unheard critical item (e.g., popa, sepa, soja, etc. for the critical item sopa). At test, participants performed free recall and yes/no recognition tasks. Replicating previous work in this paradigm, results showed robust false memory effects: that is, participants were more likely to (falsely) remember a critical item than a random intrusion. When the realization of /s/ was consistent across conditions (Experiment 1), false memory rates for varying versus non-varying words did not significantly differ. However, when the realization of /s/ varied between [s] and [h] in those positions which allow it (Experiment 2), false recognition rates for varying words like busto were significantly higher than those for non-varying words like sopa. Assuming that higher false memory rates are indicative of greater lexical activation, we interpret these results to support the predictions of exemplar theory, which claims that words with heterogeneous versus homogeneous acoustic realizations should exhibit distinct patterns of activatio

ABSTRACT
Epson Batam is a company engaged in the production of inkjet printers, digital printing systems, 3LCD projectors, smart glasses and other electrical components. . PT Epson Batam in maintaining the smooth distribution process of its products requires logistics vendors who are useful in helping smooth distribution until it reaches consumers. In this case, PT Epson found difficulties in determining logistics vendors who would carry out product distribution activities, this was due to the problem of making logistics vendor selection decisions that matched the criteria of PT. Epson Batam. The method used for vendor selection is the Analytical Hierarchy Process (AHP) method. This study aims to select the best vendor by selecting vendors based on criteria and sub-criteria with the SCOR (Supply Chain Operation Reference) approach. PT. Epson Batam is that the highest priority logistics vendor to be chosen by PT. Epson Batam is PT. PLS has an important influence with a weight value of 0.423 (42.3%), second place PT Royal Pasifik 0.267 (26.7 %), third rank PT. Daiho Batam 0.183 (18.3%) last rank is PT. Industrial Interpak 0.126 (12.6%). The value that has been obtained from the calculation by AHP (Analytical Hierarchy Process) method can be a consideration for the company in choosing a logistic vendor at PT. Epson Batam is useful in improving the supply chain strategy in company.

Malignant Perivascular Epithelioid Cell Neoplasm (PEComa) ofĀ theĀ Pelvis: A Case Report
AbstractPerivascular epithelioid cell neoplasms (PEComa) are rare mesenchymal tumors that can occur in any part of the body and have unpredictable pathological behavior. They are usually benign, but may be malignant. We present a case of malignant PEComa of the pelvic retroperitoneum treated with radical surgery
Malignant mesothelioma of tunica vaginalis testis: Report of a very rare case with review of the literature
Introduction: Mesothelioma of the tunica vaginalis testis is a extremely rare tumor and represents 0.3 to 0.5% of all malignant mesotheliomas. Exposure to asbestos often precedes illness. Because of its low incidence and nonspecific clinical presentation, it is mostly diagnosed accidentally during surgery for other reasons and the prognosis is usually poor. We present a case of a patient with a mesothelioma of tunica vaginalis testis, diagnosed secondarily during hydrocele surgery, with long-term survival after radical surgery.
Materials and methods: a 40 years old patient was admitted to our department for routine surgery of a left hydrocele. During the operation a frozen section analysis was requested because of the unusual nodular thickening of the tunica vaginalis: the examination revealed a diffuse malignant mesothelioma with epithelioid structure and tubular-papillary proliferation. Therefore a left hemi-scrotectomy with left inguinal lymph node dissection was performed.
Results: The definitive histology confirmed the previous report of diffuse malignant mesothelioma with angio-invasion but normal testicle findings and negative lymph nodes. No metastases were found on the CT-scan. For the first 2 years a CT was repeated every 4 months, for other 3 years every 6 months and then yearly. Six years after surgery the patient is classified as no evidence of disease.
Conclusions: malignant mesothelioma of the tunica vaginalis testis is a rare entity, often initially thought to be a hydrocele or an epididymal cyst. An aggressive approach with hemiscrotectomy with or without inguinal and retroperitoneal lymphadenectomy can reduce the risk of recurrence
Aneusomy of chromosomes 7 and 17 predicts the recurrence of transitional cell carcinoma of the urinary bladder
Objective To determine if changes in chromosome 7 and 17 copy number can be used to predict recurrence in patients with primary noninvasive (pTa) or superficially invasive (pT1) transitional cell carcinoma (TCC) of the urinary bladder. Patients and methods Tissue specimens for 129 tumours from 52 patients (38 men and 14 women) with pTa/pT1 TCC at first diagnosis were retrieved from pathology archives. All patient notes were accessed and disease outcome documented for superficial (pTa/ pT1) recurrence or progression to detrusor muscle invasion (greater than or equal to pT2). The rumours were examined for chromosomal copy number of chromosomes 7 and 17 using fluorescence in situ hybridization (PISH) with chromosome-specific probes. The copy number of chromosomes 7 and 17 was determined in interphase nuclei on intact 6 mu m tissue sections. Results Aneusomy of chromosomes 7 and 17 was detected in the index primary tumours of 10 of 32 (31%) patients with subsequent recurrent disease. No aneusomy for these chromosomes was detected in primary tumours from 20 patients with no detectable recurrence (P = 0.0082). The relative risk of recurrence was 3.62 times greater (95% confidence interval 1.6-8.1, Cox's multiple regression P = 0.0019) for patients with chromosomal aneusomy in primary TCC. Neither stage nor grade of the primary tumours was associated with recurrence in these patients, nor was there a significant association with increased grade (G2/3) or stage (greater than or equal to pT2) at recurrence. Conclusion These results suggest that the measurement of aneusomy by FISH, using markers for chromosomes 7 and 17, predict recurrence in a subgroup of patients with pTa/pT1 tumours at presentation. This finding may offer a new objective and quantitative test for patients destined to recur

The Role of 11C-Choline-PET/CT-Guided Secondary Lymphadenectomy in Patients with PSA Failure after Radical Prostatectomy: Lessons Learned from Eight Cases
Introduction. 11C-choline-PET/CT is a promising technique for detection/restaging of patients with biochemical failure (BF) after curative therapy for prostate cancer (PCA). The aim of this paper was to evaluate the PSA response in patients with BF after radical prostatectomy (RP) who underwent secondary lymphadenectomy (LAD) due to 11C-choline-PET/CT findings. Material and Methods. Eight patients with BF and positive lymph nodes in 11C-choline-PET/CT after RP were retrospectively included in the study. Extended LAD until the common iliac arteries was performed in all patients. Results. Six of 8 patients had histologically proven lymph node metastases. Four patients showed an initial PSA reduction after LAD, and in 4 patients the PSA increased. Two of the latter had no histological lymph node metastases. Conclusions. Because 50% of our patients showed an initial PSA response, our data suggest that positive 11C-choline-PET/CT after RP and BF could help to select patients that could benefit from secondary LAD

Pediatric Scoliosis Surgery-A Comprehensive Analysis of Treatment-Specific Variables and Trends in Latvia
Publisher Copyright: Ā© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Background and Objectives: There are currently no data available regarding pediatric scoliosis surgery in Latvia. The aim of this article is to present treatment specific variables, investigate their interrelation, and identify predictors for the length of stay after surgical pediatric scoliosis correction. Materials and Methods: This retrospective study included all surgical pediatric scoliosis corrections in Latvia for the years 2012 to 2016. Analyzed parameters were chosen to portray the patients' demographics, pathology, as well as treatment specific variables. Descriptive, inferential, and linear regression statistics were calculated. Results: A total of 69 cases, 74% female and 26% male, were identified. The diagnostic subgroups consisted of 62% idiopathic (IDI) and 38% non-idiopathic (non-IDI) scoliosis cases. Non-IDI cases had significantly increased operation time, hospital stay, Cobb angle before surgery, and instrumented levels, while IDI cases showed significantly higher Cobb angle percentage correction. For all operated cases, the operation time and the hospital stay decreased significantly over the investigated time period. Early post-operative complications (PCs) occurred in 15.9% of the cases and were associated with increased hospital stay, instrumented levels, and Cobb angle before surgery. The linear regression analysis revealed that operation time and the presence of PCs were significant predictors for the length of the hospital stay. Conclusions: This is the first study to provide comprehensive insight into pediatric scoliosis surgery since its establishment in Latvia. Our regression model offers clinically applicable predictors and further underlines the significance of the operation length on the hospital stay. These results build the foundation for international comparison and facilitate improvement in the field.publishersversionPeer reviewe
