Boviene sarcosporidiosis of eosinofiele myositis?

Sarcosporidiosis is a misused term in meat inspection to name multifocal grey-green lesions observed in muscles of cattle. Instead the correct morphological diagnosis is bovine eosinophilic myositis. The confusion in terminology can not only lead to problems in insurance cases, it also results in incorrect European data reports. This article summarizes the current knowledge of Sarcocystis and bovine eosinophilic myositis in cattle, as a plea for the correct us of terminology

G-8 indicates overall and quality-adjusted survival in older head and neck cancer patients treated with curative radiochemotherapy

Background: Evidence-based guidelines concerning the older head and neck cancer (HNCA) patient are lacking. Accurate patient selection for optimal care management is therefore challenging. We examined if geriatric assessment is indicative of long-term health-related quality of life (HRQOL) and overall survival in this unique population. Methods: All HNCA patients, aged >= 65 years, eligible for curative radio(chemo) therapy were evaluated with the Geriatric-8 (G-8) questionnaire and a comprehensive geriatric assessment (CGA). Euroqol-5 dimensions (EQ-5D) and survival were collected until 36 months post treatment start. Repeated measures ANOVA was applied to analyse HRQOL evolution in 'fit' and 'vulnerable' patients, defined by G-8. Kaplan-Meier curves and cox proportional hazard analysis were established for determination of the prognostic value of geriatric assessments. Quality-adjusted survival was calculated in both patient subgroups. Results: One hundred patients were recruited. Seventy-two percent of patients were considered vulnerable according to CGA (>= 2 abnormal tests). Fit patients maintained a relatively acceptable long-term HRQOL, whilst vulnerable patients showed significantly lower median health states. The difference remained apparent at 36 months. Vulnerability, as classified by G-8 or CGA, came forward as independent predictor for lower EQ-5D index scores. After consideration of confounders, a significantly lower survival was observed in patients defined vulnerable according to G-8, compared to fit patients. A similar trend was seen based on CGA. Calculation of quality-adjusted survival showed significantly less remaining life months in perfect health in vulnerable patients, compared to fit ones. Conclusions: G-8 is indicative of quality-adjusted survival, and should be considered at time of treatment decisions for the older HNCA patient

Serial comprehensive geriatric evaluation in older head and neck cancer patients undergoing radiotherapy

Downregulating transcription of the oncogene <i>c-MYC</i> is a feasible strategy for cancer therapy. Stabilization of the G-quadruplex structure present in the <i>c-MYC</i> promoter can suppress <i>c-MYC</i> transcription. Thus, far, several ligands targeting this structure have been developed. However, most have shown no selectivity for the <i>c-MYC</i> G-quadruplex over other G-quadruplexes, leading to uncertain side effects. In this study, through structural modification of aryl-substituted imidazole/carbazole conjugates, a brand-new, four-leaf clover-like ligand called <b>IZCZ-3</b> was found to preferentially bind and stabilize the <i>c-MYC</i> G-quadruplex. Further intracellular studies indicated that <b>IZCZ-3</b> provoked cell cycle arrest and apoptosis and thus inhibited cell growth, primarily by blocking <i>c-MYC</i> transcription through specific targeting of the promoter G-quadruplex structure. Notably, <b>IZCZ-3</b> effectively suppressed tumor growth in a mouse xenograft model. Accordingly, this work provides an encouraging example of a selective small molecule that can target one particular G-quadruplex structure, and the selective ligand might serve as an excellent anticancer agent

Phase II study of weekly paclitaxel/carboplatin in combination with prophylactic G-CSF in the treatment of gynecologic cancers: A study in 108 patients by the Belgian Gynaecological Oncology Group

Objective To investigate the addition of prophylactic G-CSF to each weekly paclitaxel/carboplatin course in patients with recurrent platinum-resistant ovarian (OC), or recurrent or advanced endometrial (EC) or cervical carcinoma (CC). Methods 108 patients were enrolled i.e. 36 in each cohort. Eighteen courses of paclitaxel (60 mg/m2) and carboplatin (AUC 2.7) were administered weekly. G-CSF (filgrastim) was given to all patients on day 5 (and if needed on day 6). Results For patients with OC, 91% had platinum-resistant and 9% platinum-refractory disease. Median number of prior chemotherapy lines was 3 for OC, 1 for EC, and 1 for CC. Grade 3-4 neutropenia was observed in 34% of patients (95% CI: 26%-44%, P < 0,0001) (OC 29%, EC 36%, CC 38%). This is lower compared to historical data in all cohorts (84%). Confirmed sepsis was observed in 5%, grade 3-4 thrombocytopenia in 41%, grade 2-3 peripheral neuropathy in 17% of patients. In 71% of patients dose was delayed. Dose reduction was necessary for carboplatin in 47% and paclitaxel in 18% of patients. ORR was 51% (OC 48%, EC 45%, CC 58%). Median (95% CI) PFS and OS was 7.1 (5.1-8.1) and 12.7 (10.2-16.3) months, respectively (OC 7 and 13, EC 6 and 19, CC 6 and 14). Conclusion Weekly paclitaxel/carboplatin with G-CSF is an effective treatment with acceptable toxicity in patients with platinum-resistant or platinum-refractory OC, advanced or recurrent EC and CC. The incidence of grade 3-4 neutropenia is lower with the addition of weekly G-CSF compared with earlier studies without routine use of prophylactic G-CSF. © 2015 Elsevier Inc. All rights reserved
