Four variables were independent predictors for AKI by logistic regression older age, lower baseline estimated glomerular filtration rate, diabetes and heart failure. AZD1656 clinical trial A risk score including these four variables had good predictive performance, with a C-statistic of 0.80 [95% confidence interval (CI) 0.80-0.81] in the development cohort and 0.71 (95% CI 0.70-0.72) in the Kent, UK external validation cohort and 0.76 (95% CI 0.75-0.76) in the Canadian validation cohort.

We have devised and externally validated a simple risk score from routinely collected data that can aid both primary and secondary care physicians in identifying patients at high risk of AKI.

The Medical Faculty of the University of Bern used a measure based on the journal impact factor (JIF) for this purpose the JIF of the papers submitted for promotion should rank in the upper third of journals in the relevant discipline (JIF rank >0.66). The San Francisco Declaration on Research Assessment (DORA) aims to eliminate the use of journal-based metrics in academic promotion. We examined whether the JIF rank could be replaced with the relative citation ratio (RCR), an article-level measure of citation impact developed by the National Institutes of Health (NIH). An RCR percentile >0.66 corresponds to the upper third of citation impact of articles from NIH-sponsored research. We examined 1525 publications submitted by 64 candidates for academic promotion at University of Bern. There was only a moderate correlation between the JIF rank and RCR percentile (Pearson correlation coefficient 0.34, 95% CI 0.29-0.38). Among the 1,199 articles (78.6%) published in journals ranking >0.66 for the JIF, less than half (509, 42.5%) were in the upper third of the RCR percentile. Conversely, among the 326 articles published in journals ranking less then 0.66 regarding the JIF, 72 (22.1%) ranked in the upper third of the RCR percentile. Our study demonstrates that the rank of the JIF is a bad proxy measure for the actual citation impact of individual articles. The Medical Faculty of University of Bern has signed DORA and replaced the JIF rank with the RCR percentile to assess the citation impact of papers submitted for academic promotion.Background Sodium hypochlorite (NaOCl) is the most commonly used irrigant in endodontics . The purpose of this study was to evaluate the effect of NaOCl solution (2.5%) and gel (3%) with/without passive ultrasonic irrigation (PUI) on Enterococcus faecalis, Escherichia coli, and their endotoxins, lipopolysaccharide (LPS) and lipoteichoic acid (LTA). Methods 40 human lower premolars were contaminated with E. coli (ATCC 25922) for 28 days and E. faecalis (ATCC 29212) for 21 days. Specimens were randomly divided into four groups (1) 2.5% NaOCl irrigating the canals without PUI activation; (2) 2.5% NaOCl with PUI; (3) 3% NaOCl gel irrigating the canals without PUI; and (4) 3% NaOCl gel with PUI. link2 40 mL of irrigant was used for each group. PUI activation was carried out using E1-Irrisonic stainless-steel tip at 10% frequency. After treatment, all specimens were filled with 3mL of 17% ethylenediaminetetraacetic acid (EDTA) for 3min and then washed with nonpyrogenic saline solution. Three samples were collected from the canals S1, at baseline to confirm biofilm formation; S2 after treatment; and S3 after EDTA. Samples were assessed for E. coli and E. faecalis colony forming units, and LPS and LTA were assessed using chromogenic kinetic LAL assay and ELISA, respectively. Data were analyzed by Kruskal-Wallis, Friedmann and Dunn tests with α≤0.05. Results All groups were effective in reducing the microbial load of E. coli and E. faecalis after treatment without a significant difference among the groups. NaOCl and NaOCl gel groups had no significant difference in reducing LPS and LTA. Statistically increased reduction was seen for NaOCL + PUI and NaOCl gel + PUI compared for groups without PUI. Conclusions NaOCl gel has the same antimicrobial action of NaOCl solution and can partially detoxify endotoxins. PUI improves NaOCl (gel or solution) action over E. faecalis and E. coli and their endotoxins.Trichloroethylene exposure is a major risk factor for pulmonary veno-occlusive disease. link3 We demonstrated that trichloroethylene alters the endothelial barrier integrity, at least in part, through vascular endothelial (VE)-Cadherin internalisation, and suggested that this mechanism may play a role in the development of pulmonary veno-occlusive disease.We report a case of primary tracheal schwannoma in a 31-year-old woman. She had a previous history of follicular thyroid carcinoma treated surgically and Turner syndrome. In a follow-up computed tomography scan, we found a partially obstructing intraluminal tracheal tumor, which was confirmed by bronchoscopy. The patient was treated by surgical resection and primary tracheal anastomosis. The tumor was 14 mm in diameter, with an intact capsule. Histologic analysis revealed a Schwann cell origin tumor.We report our experience with two patients who underwent omphalomesenteric duct resection one for a patent omphalomesenteric duct and the other for a Meckel diverticulum connected to the umbilicus by a fibrous cord. We used an intraumbilical round incision and a transumbilical vertical incision, respectively. The first patient was a neonate with a patent omphalomesenteric duct who appeared to have a small stoma after ligature of the umbilical cord. Contrast media, injected through a catheter inserted into the stoma, entered the lumen of the small bowel. The second patient was an infant with a Meckel diverticulum connected to the umbilicus by a fibrous cord. After bloody stool was noted, nuclear imaging using 99m technetium pertechnetate revealed a small, round area of intense tracer activity in the midabdomen, suggesting the presence of ectopic gastric mucosa. Using either an intraumbilical or a transumbilical incision is safe and provides good cosmesis.Splenosis is an autotransplantation of splenic tissue following traumatic rupture of the spleen or splenectomy. Generally, splenosis is asymptomatic. Therefore, most cases are incidental findings made during surgery, autopsy or after imaging studies for other purposes. Splenosis is a benign phenomenon, but it often shows similarity to the metastatic process. We present a case of asymptomatic intraperitoneal splenosis occurring in a 57-year-old male, in whom computed tomography urography showed lymphadenopathy suggesting a neoplastic process. A reconnaissance laparotomy was performed, and specimens were taken and sent for histopathological examination. The microscopic image of all the collected lesions corresponded to the normal spleen tissue. Due to an increasing number of traffic accidents, it is worth taking abdominal splenosis into consideration in the differential diagnosis of tumor-like changes, especially in patients with a history of splenic trauma or spleen removal. As a result, unnecessary surgery can be avoided in many cases.The burden of cancer is increasing in sub-Saharan Africa due to ageing, common risk factors and population growth. Anal cancer is a human papillomavirus-related rare disease with an incidence rate of 1.8 per 100 000 persons overall with an increasing incidence of by 2% per year in the last three decades. Despite that gold standard management is well described, in low-income countries, there is no possibility for a proper management. We presented a late-stage anal cancer case that reflects the urgent necessity to create the adequate condition for the development of effective oncologic approach including prevention, diagnosis and management.Sarcomatoid malignant peritoneal mesothelioma is the rarest and most lethal form of peritoneal mesothelioma. We present the case of a sarcomatoid malignant peritoneal mesothelioma presenting as a localized mesenteric tumor in a 54-year-old female with no previous asbestos exposure. This clinical presentation is extremely rare and is the first documented in Cameroon.A 64-year-old male with no history of trauma presented to the general surgery clinic with a 6-month history of an asymptomatic left parietal scalp mass. The differential included benign etiologies such as lipoma or sebaceous cyst. At surgery, a hemorrhagic soft tissue mass with underlying defect in the parietal calvarium was noted. The initial attempt at resection was abandoned and neurosurgical consultation was requested. Magnetic resonance imaging demonstrated an enhancing scalp mass with a lytic lesion of the parietal calvarium with no intradural extension. Craniectomy with mass resection and mesh cranioplasty were performed. Pathology confirmed plasma cell neoplasm; serum protein electrophoresis and lytic skull lesions confirmed multiple myeloma. This rare presentation of multiple myeloma serves as a call for providers to maintain a broad differential when evaluating a seemingly benign mass, consider rare etiologies when appropriate and maintain vigilance for abnormal findings during any procedure.
In this study, we aimed to investigate the differences in the intrinsic functional connectivity (iFC) of the primary visual cortex (V1), based on resting-state functional magnetic resonance imaging (rs-fMRI), between patients with proliferative diabetic retinopathy (PDR) and healthy controls (HCs).

In total, 26 patients (12 males, 14 females) with PDR and 26 HCs (12 males, 14 females), matched for sex, age, and education status, were enrolled in the study. All individuals underwent rs-fMRI scans. We acquired iFC maps and compared the differences between PDR patients and the HCs.

The PDR group had significantly increased FC between the left V1 and the right middle frontal gyrus (RMFG), and significantly reduced FC between the left V1 and the cuneus/calcarine/precuneus. In addition, the PDR patients had significantly increased FC between the right V1 and the right superior frontal gyrus (RSFG), and significantly reduced FC between the right V1 and the cuneus/calcarine/precuneus. The individual areas underechanisms related to PDR and possible approaches for the early identification of PDR.
Diabetes mellitus (DM) is an established risk factor for intermittent claudication (IC) and other manifestations of atherosclerotic peripheral arterial disease. Indications for surgery in infrainguinal IC are debated, and there are conflicting reports regarding its outcomes in patients with DM. Aims of this study were to compare both short- and long-term effects on total- and cardiovascular (CV) mortality, major adverse cardiovascular events (MACEs), acute myocardial infarction (AMI), stroke, and major amputation following infrainguinal endovascular surgery for IC in patients with and without DM. We also evaluated potential relationships between diabetic control and outcomes in patients with DM.

Nationwide observational cohort study of patients registered in the Swedish Vascular Registry and the Swedish National Diabetes Registry. Propensity score adjusted comparison of total and CV mortality, MACE, AMI, stroke, and major amputation after elective infrainguinal endovascular surgery for IC in 626 patients with and 1112 without DM at 30 postoperative days and after median 5.
