The Juvenile Arthritis Multidimensional Assessment Report (JAMAR) is a new parent/patient reported outcome measure that enables a thorough assessment of the disease status in children with juvenile idiopathic arthritis (JIA). We report the results of the cross-cultural adaptation and validation of the parent and patient versions of the JAMAR in the Slovene language. The reading comprehension of the questionnaire was tested in 10 JIA parents and patients. Each participating centre was asked to collect demographic, clinical data and the JAMAR in 100 consecutive JIA patients or all consecutive patients seen in a 6-month period and to administer the JAMAR to 100 healthy children and their parents. The statistical validation phase explored descriptive statistics and the psychometric issues of the JAMAR: the 3 Likert assumptions, floor/ceiling effects, internal consistency, Cronbach’s alpha, interscale correlations, test–retest reliability, and construct validity (convergent and discriminant validity). A total of 100 JIA patients (7.0% systemic, 47.0% oligoarticular, 22.0% RF negative polyarthritis, 24.0% other categories) and 120 healthy children, were enrolled. The JAMAR components discriminated well healthy subjects from JIA patients, except for the Health-Related Quality of Life, Psychosocial Health subscales. All JAMAR components revealed good psychometric performances. In conclusion, the Slovene version of the JAMAR is a valid tool for the assessment of children with JIA and is suitable for use both in routine clinical practice and clinical research.

The objective of article is to provide important empirical evidence to support the role of individual knowledge management processes and separate innovation types within firms. Specifically, knowledge acquisition and knowledge application are analyzed and empirically tested in relation to product and process innovation as well as business performance. The results support the direct impact of product and process innovation on business performance. In addition, the results show the indirect effect of knowledge acquisition and knowledge application on firm business performance through product and process innovation. Although KM represents a complex concept of knowledge management in a firm and can contain more processes, this article confirms that KM processes individually contribute to the innovation and indirectly on business performance. Besides, it confirms mediating effect of innovation between both knowledge acquisition and knowledge application and organizational business performance. In addition, most of the similar studies have been focused on the developed Western countries.

Background The purpose of this study is to establish whether the lymph node metastases of the papillary thyroid carcinoma are a significant factor in recurrence of the disease by analyzing the time until recurrence of the disease and frequency of recurrence of the disease. Methods From 1 January 1995 until 30 June 2017, 102 patients were treated at the Public Health Institute Hospital “Sveti Vracevi” in Bijeljina for PTC. In all patients, surgery of the thyroid gland and/or lymph nodes of the neck was performed. Total thyroidectomy (TT) was performed in 20 patients and near-total thyroidectomy leaving <1 g thyroid tissue adjacent to the recurrent laryngeal nerve in 7 patients. TT and lymph nodes dissection were performed in 71 patients. Palliative surgery and biopsy due to locally advanced disease were performed in 3 patients. Results In our study, 102 patients with PTC were analyzed. 82 patients experienced pure PTC (80.4%), the other 20 patients (19.6%) experienced other variants of PTC. 24 patients (23.5%) experienced multi centric or bilateral tumors. 71 patients (69.6%) experienced histologically verified metastases in the lymph nodes of the neck. 7 patients (6.8%) experienced distant metastases. 20 patients underwent total thyroidectomy (TT), and 7 near-total thyroidectomy. Total thyroidectomy + dissection of central and lower jugular lymph nodes with frozen section histopathology verification was performed in 71 patients (69.6%). Out of these 71 patients, in 50 patients (70.4%) metastases were verified in the lower jugular lymph nodes. A modified lymph node dissection (MRND) was also performed in these patients. Conclusion Lymph node metastases of the papillary thyroid carcinoma are a plausible prognostic factor. They are important for recurrence of the disease, but not for survival.

Introduction Duplicated ureter or Duplex Collecting System is a congenital condition in which the ureteric bud, the embryological origin of the ureter, arises twice, resulting in two ureters draining a single kidney. This congenital anomaly is rare, and even rarer when the duplex system with ectopic ureter is present. This type of congenital anomaly is even more rarely diagnosed and surgically treated in adulthood. Case report This case report presents a case of a 32-year-old male, who had a duplex collecting system with two ureters on the left side. Ectopic ureter, draining the upper pole of the left kidney, opened into the posterior urethra. In our patient, taking into account the clinical perspective, the renal tissue damaging of the upper pole which was not functional, partial nephrectomy and ureterectomy was successfully performed.

Background: There is insufficient knowledge regarding the influence of concomitant injuries on the recovery of short-term subjective knee function after anterior cruciate ligament (ACL) reconstruction. Purpose: To determine whether patient characteristics, concomitant injuries, and graft choice during ACL reconstruction can predict which patients achieve acceptable knee function 1 year after reconstruction. Study Design: Case-control study; Level of evidence, 3. Methods: Data from 1 physical therapist–specific and 1 surgeon-specific register were used. Patients who had completed the Knee injury and Osteoarthritis Outcome Score (KOOS) at 1-year follow-up were included. Additional intraoperative information was extracted from a database. The primary outcome was achieving a patient-acceptable symptom state (PASS) for each subscale of the KOOS. Univariable and multivariable logistic regression models were used, with patient sex, age, and preinjury level of physical activity as covariates. Results: A total of 343 patients (51% females) were included. The proportion of patients achieving PASS 1 year after ACL reconstruction varied between 40% and 85% among the KOOS subscales. Younger age at reconstruction and male sex provided favorable odds of achieving acceptable knee function across the KOOS subscales. Patients without cartilage injury had increased odds of achieving PASS in the KOOS sport and recreation subscale; the increase was 1.63-fold (95% CI, 1.01-2.64; P = .045). Patients receiving patellar tendon autograft had a 0.41-fold (95% CI, 0.19-0.85; P = .017) decrease in odds of achieving PASS on the KOOS quality of life (QoL) subscale. In the multivariable analysis, increased odds of achieving PASS on the KOOS QoL subscale were associated with the absence of meniscal injury (odds ratio, 1.62; 95% CI, 1.04-2.54; P = .035), and increased odds were found for hamstring tendon autograft (OR, 2.63; 95% CI, 1.25-5.56; P = .011). Conclusion: More than half of the patients reported an acceptable symptom state on 4 of the 5 KOOS subscales 1 year after ACL reconstruction. A lack of consistency was noted related to the effect of concomitant knee injuries and graft choice on acceptable knee function. However, younger age and male sex were favorable, nonmodifiable characteristics that increased the odds of early acceptable function.
