Uitleg over een nieuwe regeling voor het bijenteeltonderwijs. Omdat het in de praktijk voor veel verenigingen onmogelijk geworden is om via een AOC een cursus te organiseren, heeft de georganiseerde bijenhouderij zelf de verantwoordelijkheid genomen. Als verenigingen een cursus organiseren die overeenstemt met de richtlijnen kunnen zij de cursisten een diploma verstrekken dat erkend wordt door de beroepsgroep van imkers en de bijenhoudersorganisatie

The impact of menstruation persistence or recovery after chemotherapy on survival in young patients with hormone receptor negative breast cancer
Introduction: Hormone replacement therapy can diminish hormone depletion-related complaints in
postmenopausal women, but is contraindicated for postmenopausal breast cancer (BC) patients. Recovery of menstruation after chemotherapy-induced amenorrhea in young hormone receptor-negative
BC patients however, is accepted. To determine the safety of this strategy, we investigated the effect of
recovery of menstruation on disease-free survival (DFS) and overall survival (OS) in young hormone
receptor-negative BC patients treated with (neo)adjuvant chemotherapy.
Methods: We selected 636 patients from a single-center cohort with early stage hormone receptornegative BC and under the age of 50 years when treated with chemotherapy. Sufficient data on course
of menstruation in medical records was retrospectively found for 397 patients, of whom 299 patients
(75%) had a recovery of menstruation after chemotherapy. We used Cox proportional hazards models to
estimate hazard ratios (HR) for the effect of recovery of menstruation on DFS and OS.
Results: Patients with recovery of menstruation after chemotherapy less frequ
Impact of DNA damage repair defects and aggressive variant features on response to carboplatin-based chemotherapy in metastatic castration-resistant prostate cancer
Platinum-based chemotherapy is not standard of care for unselected or genetically
selected metastatic castration-resistant prostate cancer (mCRPC) patients. A retrospective
assessment of 71 patients was performed on platinum use in the
Netherlands. Genetically unselected patients yielded low response rates. For a
predefined subanalysis of all patients with comprehensive next-generation sequencing,
30 patients were grouped based on the presence of pathogenic aberrations in
genes associated with DNA damage repair (DDR) or aggressive variant prostate cancer
(AVPC). Fourteen patients (47%) were DDR deficient (DDRd), of which seven
with inactivated BRCA2 (BRCA2mut). Six patients classified as AVPC. DDRd patients
showed beneficial biochemical response to carboplatin, largely driven by all
BRCA2mut patients having >50% prostate-speci
Pancreatitis of biliary origin, optimal timing of cholecystectomy (PONCHO trial):Study protocol for a randomized controlled trial
Background: After an initial attack of biliary pancreatitis, cholecystectomy minimizes the risk of recurrent biliary pancreatitis and other gallstone-related complications. Guidelines advocate performing cholecystectomy within 2 to 4 weeks after discharge for mild biliary pancreatitis. During this waiting period, the patient is at risk of recurrent biliary events. In current clinical practice, surgeons usually postpone cholecystectomy for 6 weeks due to a perceived risk of a more difficult dissection in the early days following pancreatitis and for logistical reasons. We hypothesize that early laparoscopic cholecystectomy minimizes the risk of recurrent biliary pancreatitis or other complications of gallstone disease in patients with mild biliary pancreatitis without increasing the difficulty of dissection and the surgical complication rate compared with interval laparoscopic cholecystectomy.Methods/Design: PONCHO is a randomized controlled, parallel-group, assessor-blinded, superiority multicenter trial. Patients are randomly allocated to undergo early laparoscopic cholecystectomy, within 72 hours after randomization, or interval laparoscopic cholecystectomy, 25 to 30 days after randomization. During a 30-month period, 266 patients will be enrolled from 18 hospitals of the Dutch Pancreatitis Study Group. The primary endpoint is a composite endpoint of mortality and acute re-admissions for biliary events (that is, recurrent biliary pancreatitis, acute cholecystitis, symptomatic/obstructive choledocholithiasis requiring endoscopic retrograde cholangiopancreaticography including cholangitis (with/without endoscopic sphincterotomy), and uncomplicated biliary colics) occurring within 6 months following randomization. Secondary endpoints include the individual endpoints of the composite endpoint, surgical and other complications, technical difficulty of cholecystectomy and costs.Discussion: The PONCHO trial is designed to show that early laparoscopic cholecystectomy (within 72 hours) reduces the combined endpoint of mortality and re-admissions for biliary events as compared with interval laparoscopic cholecystectomy (between 25 and 30 days) after recovery of a first episode of mild biliary pancreatitis.</p
