Automated classification of polyps using deep learning architectures and few-shot learning.

Background: Colorectal cancer is a leading cause of cancer-related deaths worldwide. The best method to prevent CRC is a colonoscopy. However, not all colon polyps have the risk of becoming cancerous.

[Endovascular aortic replacement in a patient with bicuspid aortic valve disease].

A 49-year-old male with a history of left ventricular systolic function dilated cardiomyopathy and severe symptomatic bicuspid aortic stenosis recently diagnosed (syncope, chest pain and dyspnea) was admitted to the coronary care unit. During hospitalization, he developed cardiogenic shock requiring double inotropic support. High surgical risk and an elevated chance of graft rejection contraindicated surgical replacement or heart transplant.

A Research Agenda to Better Understand the Human Dimensions of Energy Transitions.

The Social Sciences and Humanities (SSH) have a key role to play in understanding which factors and policies would motivate, encourage and enable different actors to adopt a wide range of sustainable energy behaviours and support the required system changes and policies. The SSH can provide critical insights into how consumers could be empowered to consistently engage in sustainable energy behaviour, support and adopt new technologies, and support policies and changes in energy systems. Furthermore, they can increase our understanding of how organisations such as private and public institutions, and groups and associations of people can play a key role in the sustainable energy transition.

Ecological and functional consequences of coastal ocean acidification: Perspectives from the Baltic-Skagerrak System.

Ocean temperatures are rising; species are shifting poleward, and pH is falling (ocean acidification, OA). We summarise current understanding of OA in the brackish Baltic-Skagerrak System, focussing on the direct, indirect and interactive effects of OA with other anthropogenic drivers on marine biogeochemistry, organisms and ecosystems. Substantial recent advances reveal a pattern of stronger responses (positive or negative) of species than ecosystems, more positive responses at lower trophic levels and strong indirect interactions in food-webs.

Societal causes of, and responses to, ocean acidification.

Major climate and ecological changes affect the world's oceans leading to a number of responses including increasing water temperatures, changing weather patterns, shrinking ice-sheets, temperature-driven shifts in marine species ranges, biodiversity loss and bleaching of coral reefs. In addition, ocean pH is falling, a process known as ocean acidification (OA). The root cause of OA lies in human policies and behaviours driving society's dependence on fossil fuels, resulting in elevated CO concentrations in the atmosphere.

The transforming capacity of collaborative institutions: Belief change and coalition reformation in conflicted wildlife management.

The aim of this study is to examine the transformative capacity of top-down imposed collaborative institutions on participants' beliefs and coordination patterns. First, do collaborative arenas enhance learning in terms of belief change and belief convergence among participating actors? Second, what types of beliefs are changed and, third, how are changes in beliefs reflected in the formation of coalitions? To answer these questions, a longitudinal study encompassing three collaborative decision-making arenas in the highly adversarial system for wildlife management in Sweden is performed. The empirical analysis indicates both stability and change within the new management system that confirms, as well as challenges, the theoretical assumptions guiding the analysis.

Physiological and biological predictors of length of stay and recovery in adults with acute asthma: An observational cohort study.

Introduction: Asthma is a prevalent, chronic disease associated with significant risk to patients and cost to healthcare systems. Accurate estimates of length of stay and recovery are important for patient information, physician prognostication, and management of inpatient beds.

Objectives: To assess factors affecting length of stay and time to recovery in adults with acute asthma.

Governing sexual behaviour through humanitarian codes of conduct.

Since 2001, there has been a growing consensus that sexual exploitation and abuse of intended beneficiaries by humanitarian workers is a real and widespread problem that requires governance. Codes of conduct have been promoted as a key mechanism for governing the sexual behaviour of humanitarian workers and, ultimately, preventing sexual exploitation and abuse (PSEA). This article presents a systematic study of PSEA codes of conduct adopted by humanitarian non-governmental organisations (NGOs) and how they govern the sexual behaviour of humanitarian workers.

Childhood caries is still in force: a 15-year follow-up.

Objective: To examine changes in caries prevalence among 3 to 15-year-old adolescents.

Material And Methods: Of 1582 eligible mothers, 1443 gave informed consent. Participating children and their parents were followed up continuously from 3 to 15 years of age in a pre-planned fashion and at regular intervals.

Effects of recombinant human interleukin-12 on eosinophils, airway hyper-responsiveness, and the late asthmatic response.

Background: Interleukin-12 (IL-12) is a macrophage-derived cytokine that modulates T lymphocyte responses and has the capacity to suppress allergic and eosinophilic inflammation.

Methods: We carried out a double-blind, randomised, parallel group clinical study, in which patients with mild allergic asthma were given subcutaneous recombinant human IL-12 at increasing weekly injections of 0.1, 0.
