Determination of the mineral content of bee honeys produced in Middle Anatolia

The mineral content of 43 honey samples from the middle regions of Turkey was investigated. Minerals were determined by inductively coupled plasma-atomic emission spectrophotometer. Calcium, potassium, sodium and phosphorus were the most abundant of the elements in all the studied honeys, with average concentrations ranging between 40.13 and 189.69 mg/kg for calcium, 161.01 and 598.62 mg/kg for potassium, 9.34 and 45.9 mg/kg for sodium, and 460.11 and 3,776.96 mg/kg for phosphorus. Cluster analysis of the honey data revealed that the mineral content of Corum and Konya honeys was closer as they formed a cluster at a similarity level of 60%.     

Impact of lymph node dissection at the time of radical nephrectomy with tumor thrombectomy on oncological outcomes: Results from the International Renal Cell Carcinoma-Venous Thrombus Consortium (IRCC-VTC)

Objectives

To study the effect of lymph node dissection (LND) at the time of nephrectomy and tumor thrombectomy on oncological outcomes in patients with renal cell carcinoma (RCC) and tumor thrombus.

Eligibility of patients for minimally invasive breast cancer therapy based on MRI analysis of tumor proximity to skin and pectoral muscle

There is growing interest in minimally invasive breast cancer therapy. Eligibility of patients is, however, dependent on several factors related to the tumor and treatment technology. The aim of this study is to assess the proportion of patients eligible for minimally invasive breast cancer therapy for different safety and treatment margins based on breast tumor location. Patients with invasive ductal cancer were selected from the MARGINS cohort. Semiautomatic segmentation of tumor, skin, and pectoral muscle was performed in Magnetic Resonance images. Shortest distances of tumors to critical organs (ie, skin and pectoral muscle) were calculated. Proportions of eligible patients were determined for different safety and treatment margins. Three‐hundred‐forty‐eight patients with 351 tumors were included. If a 10 mm safety margin to skin and pectoral muscle is required without treatment margin, 72.3% of patients would be eligible for minimally invasive treatment. This proportion decreases to 45.9% for an additional treatment margin of 5 mm. Shortest distances between tumors and critical organs are larger in older patients and in patients with less aggressive tumor subtypes. If a 10 mm safety margin to skin and pectoral muscle is required, more than two‐thirds of patients would be eligible for minimally invasive breast cancer therapy.     

Sex-Related Differences Include Stage,Histology, and Survival in Urethral Cancer Patients

PurposeTo test the effect of sex on histologic subtype, stage at presentation, treatment, and cancer-specific mortality (CSM) in urethral cancer.Patients and MethodsWe identified urethral cancer patients within the Surveillance, Epidemiology, and End Results (SEER) registry (2004-2016). After matching for tumor and patient characteristics, cumulative incidence plots and multivariable competing risks regression models, adjusted for other-cause mortality, tested CSM according to sex.ResultsOf 1645 eligible urethral cancer patients, 1073 (65%) were male. Urothelial histologic subtype was most frequent in male (59%) but not female (27%) subjects. Adenocarcinoma, squamous cell carcinoma, and other histologies were more frequent in female patients. Most male subjects harbored T1N0M0 (32%) stage disease, whereas most female subjects harbored T3-4N0M0 (29%) stage disease. In urothelial and adenocarcinoma histologic subtypes, African American female subjects were most prevalent (31 and 78%) versus whites (16 and 52%) versus Hispanics (27 and 74%). In T1N0M0 stage, single-mode surgical treatment was more frequent in male than female patients (respectively, 73% vs 59%). In T3-4 and/or N1-2 stage disease, multimodal therapy was more frequent in female than male (42% vs 37%) patients. In nonmetastatic urethral cancer (T1-4N0-2M0), after propensity score matching for stage, race, treatment, and age, cumulative incidence plots showed 5-year CSM of 36% and 25% in female and male patients, respectively, and after further multivariable adjustment resulted in 1.3-fold higher CSM in female as opposed to male patients (P = .07).ConclusionFemale patients with urethral cancer present with higher disease stage. Despite higher rates of multimodal therapy, and despite matching for stage disadvantage, female subjects with urethral cancer exhibited higher CSM.     

Retrospective analyzes of adverse events during biologic agents in children with juvenile idiopathic arthritis from a single center in Turkey

ObjectivesJuvenile idiopathic arthritis is the most common rheumatic disease in childhood. Biologic agents have changed the course of juvenile idiopathic arthritis. However, there are concerns regarding the occurrence of serious adverse events in patients receiving biologic agents. The aim of this study was to evaluate adverse events in children with juvenile idiopathic arthritis receiving biologic agents.Material and methodsThis retrospective study includes juvenile idiopathic arthritis patients receiving biologic agents. Demographic features and adverse events during biologic agents were collected from medical files. Adverse events that either resulted in death, were life-threatening, required inpatient hospitalization, or resulted in persistent or significant disability/incapacity were considered as serious adverse events.ResultsIn total, 162 juvenile idiopathic arthritis patients (55.6% female) receiving biologic agents were enrolled: 101 (62.3%) patients treated with etanercept, 27 (16.7) with tocilizumab, 14 (8.6%) with adalimumab, 15 (9.2%) with anti-interleukin 1 agents (13 canakinumab, 2 anakinra), and 5 (3.1%) with infliximab. 75.9% of the patients received concomitantly disease-modifying anti-rheumatic drugs, and 20.4% received disease-modifying anti-rheumatic drugs plus corticosteroid. The mean age at initiation of the biologic agent was 10.5 ±4.3 years. The mean age at the study enrolment was 12.1 ±4.5 years. The mean follow-up duration was 19.7 ±2.1 months. The most frequent adverse event was upper respiratory tract infections (54.3%) followed by urinary tract infections (21%). Anaphylaxis occurred in 3 patients (1.9%): 2 with tocilizumab and one with infliximab. Macrophage activation syndrome occurred in 1 patient (0.6%) receiving tocilizumab. Lung tuberculosis developed in 2 patients (1.2%) receiving canakinumab. The frequency of serious adverse events in total was 6.7%.ConclusionsWhile the most frequent adverse events during biologic agents was upper respiratory tract infections, the frequency of serious adverse events was 6.7%; therefore, juvenile idiopathic arthritis patients receiving biologic agents should be carefully evaluated for these adverse events in clinical practice.
