BACKGROUND: The long-term outcome after local excision of T1 colorectal cancer (CRC) remains unknown. The aim of this study was to examine clinical and histopathological risk factors for recurrence in patients with T1 CRC undergoing endoscopic resection.METHODS: This was a retrospective registry-based population study on prospectively collected data of all patients with nonpedunculated T1 CRC unde
The spruce bark beetle Ips typographus is the most damaging pest in European spruce forests and has caused great ecological and economic disturbances in recent years. Although native to Eurasia, I. typographus has been intercepted more than 200 times in North America and could establish there as an exotic pest if it can find suitable host trees. Using in vitro bioassays, we compared the preference
As the COVID-19 pandemic continues to affect societies across the world, the ongoing economic and social disruptions are likely to present fundamental challenges for current and future biodiversity conservation. We review the literature for outcomes of past major societal, political, economic and zoonotic perturbations on biodiversity conservation, and demonstrate the complex implications of pertu
Purpose: Dynamic positron emission tomography (PET) protocols allow for accurate quantification of [18F]flortaucipir-specific binding. However, dynamic acquisitions can be challenging given the long required scan duration of 130 min. The current study assessed the effect of shorter scan protocols for [18F]flortaucipir on its quantitative accuracy. Procedures: Two study cohorts with Alzheimer’s dis
The mucopolysaccharidoses (MPS) are lysosomal storage disorders that result from defects in the catabolism of glycosaminoglycans. Impaired muscle, bone, and connective tissue are typical clinical features of MPS due to disruption of the extracellular matrix. Markers of MPS disease pathology are needed to determine disease severity and monitor effects of existing and emerging new treatments on dise
Objectives: The Early Manifest Glaucoma Trial (EMGT) will evaluate the effectiveness of reducing intraocular pressure (lOP) in early, previously untreated open-angle glaucoma. Its secondary aims are to explore factors related to glaucoma progression and to study the natural history of the disease. This article describes the EMGT design and presents baseline data. Design: Randomized, clinical trial
Alpha 1-Microglobulin (alpha 1-m), or protein HC, a low molecular weight plasma protein with immunoregulatory properties, was isolated from rat serum by affinity chromatography using Sepharose-coupled monoclonal anti-alpha 1-m antibodies. High molecular weight forms of alpha 1-m were then separated from the low molecular weight alpha 1-m by gel chromatography of the eluted proteins. The apparent M
Aim: Accumulated data suggest that routine use of defunctioning stoma in low anterior resection for rectal cancer may cause kidney injury, bowel dysfunction and a higher risk of permanent stomas. We aim to study whether avoidance of a diverting stoma in selected patients is safe and reduces adverse consequences. Methods: SELSA is a multicentre international prospective observational study nesting
Background: SARS-CoV-2, the causal agent of COVID-19, enters human cells using the ACE2 (angiotensin-converting enzyme 2) protein as a receptor. ACE2 is thus key to the infection and treatment of the coronavirus. ACE2 is highly expressed in the heart and respiratory and gastrointestinal tracts, playing important regulatory roles in the cardiovascular and other biological systems. However, the gene
OBJECTIVES: Combination chemotherapy regimens have shown promising results in patients with metastatic colorectal cancer. However, only very few studies have studied the effect of palliative chemotherapy in peritoneal carcinomatosis (PC) and no data are present incorporating biological therapies in the treatment of PC in colorectal cancer.METHODS: By means of merging with the regional Eindhoven Ca
Purpose: This study investigated the use of surface guided radiotherapy (SGRT) in combination with a tomotherapy treatment mode using discrete delivery angles for deep inspiration breath hold (DIBH) treatments of breast cancer (bc). We aimed to assess the feasibility and dosimetric advantages of this approach. Materials and methods: We evaluated camera occlusion in the Radixact treatment system bo
Background: In January 2010, the choice reform was instituted in Swedish primary health care establishing free entry for private primary health care providers and enabling patients to choose freely among primary health care centers. The motivation behind the reform was to improve access to primary care and responsiveness to patient expectations. Reform effects on health care utilization have previ
The only way to combat the depletion of resources and climate crisis is to reduceour dependence on fossil fuels. Renewable sources, such as wind and solar energy,are increasingly used to meet our ever-growing energy demands; however, they areintermittent. One promising solution to the power crisis in the world is fuel cells,which, unlike the combustion engine, can operate on renewable fuels such a
The Covid-19 pandemic has changed our lives. The first and unexpected lockdown in Italy has seriously upset people daily routine, working organisation, socialisation and interactions with colleagues and relatives. To overcome the physical isolation and collect impressions, the “How are you?” online questionnaire was created and shared as a conversation among friends. Text mining techniques have be
We introduce the concept of a k-dimensional matrix product D of k matrices (Formula presented.) of sizes (Formula presented.) respectively, where (Formula presented.) is equal to (Formula presented.). We provide upper bounds on the time complexity of computing the product and solving related problems of computing witnesses and maximum witnesses of the Boolean version of the product in terms of the
BACKGROUND: The study aimed to show the relationship between a large number of circulating metabolites and subsequent cardiovascular disease (CVD) and subclinical markers of CVD in the general population. METHODS AND RESULTS: In 2278 individuals free from CVD in the EpiHealth study (aged 45–75 years, mean age 61 years, 50% women), 790 annotated nonxenobiotic metabolites were measured by mass spect
Background: There has been a controversy regarding the cause of brachioradial pruritus: is it caused by a nerve compression in the cervical spine or is it caused by a prolonged exposure to sunlight? Objective: The purpose was to study clinical features of patients with brachioradial pruritus and to compare the cutaneous innervation in punch biopsies from the itchy skin of patients with the age-mat
Should boxing be banned? Do the ever-so-obvious risks outweigh everyone's freedom to choose whether to expose oneself to these risks by taking up the sport? On an official level, the RCN in the UK has taken its stand--it does not! So has also the British Medical Association (BMA)--it does! With few exceptions, the responding nurses from Europe, America, and Australia in this month's column seem to

Background: Air pollution has been linked to breast cancer risk, but previous studies have seldom considered specific exposure windows, like pregnancy. During pregnancy the breast undergoes substantial changes and exposures may have a stronger impact than if they occurred during other time periods. This study aims to identify associations between ambient air pollution exposure during pregnancy and
