The cost-effectiveness of six edge-of-field measures for mitigating diffuse pollution from sediment bound phosphorus (P) runoff from temperate arable farmland is analysed at catchment/field scales. These measures were: buffer strips, permanent grassland in the lowest 7% of arable fields, dry detention bunds, wetlands, and temporary barriers such as sediment fences. Baseline field P export was estimated using export coefficients (low risk crops) or a modified Universal Soil Loss Equation (high risk crops). The impact of measures was estimated using simple equations...

Spontaneous adrenal hemorrhage (SAH) is a serious medical condition associated with variable clinical presentation depending on the extent of the hemorrhage. Pregnancy-induced adrenal hemorrhage is poorly understood. A low cortisol level in the peripartum period with radiological findings is sufficient to establish the diagnosis. Prompt hormone replacement and supportive care to ensure good clinical outcomes is crucial. Due to the potentially life-threatening complications, physicians should have a high suspicion for adrenal hemorrhage when they evaluate patients with hypotension, fatigue, and abdominal pain during the peripartum period...

BACKGROUND: Globally, most patients with hypertension are treated with monotherapy, and control rates are poor because monotherapy only reduces blood pressure by around 9/5 mm Hg on average. There is a pressing need for blood pressure-control strategies with improved efficacy and tolerability. We aimed to assess whether ultra-low-dose combination therapy could meet these needs. METHODS: We did a randomised, placebo-controlled, double-blind, crossover trial of a quadpill-a single capsule containing four blood pressure-lowering drugs each at quarter-dose (irbesartan 37·5 mg, amlodipine 1·25 mg, hydrochlorothiazide 6·25 mg, and atenolol 12·5 mg)...

Venous thromboembolism (VTE) is a commonly encountered problem in patients with cancer. In recent years, cancer treatment paradigm has shifted with most therapy offered in ambulatory outpatient settings. Excess of half VTEs in patients with cancer occur in outpatient settings without prior hospitalization, where current practice guidelines do not recommend routine prophylaxis. Risk assessment models (RAMs) for VTE in such patients were recently introduced. This study aims to assess the practical application of one of these models in clinical practice...

Band-like calcification with simplified gyration and polymicrogyria (BLC-PMG) is an extremely rare autosomal recessive disorder with distinctive clinical and neuroimaging findings. To date, only 17 patients from 9 unrelated families with BLC-PMG have been reported worldwide. Herein, we describe a series of 13 new patients derived from 10 unrelated Egyptian families. Patients presented at early life with the classic phenotype including severe microcephaly, failure to acquire developmental skills, growth failure and the distinguished calcification patterns involving the cortex, thalami, basal ganglia and pons...

BACKGROUND: Macrophages cover a major role in the immune system, being the most plastic cell yielding several key immune functions. METHODS: Here we derived a minimalistic gene regulatory network model for the differentiation of macrophages into the two phenotypes M1 (pro-) and M2 (anti-inflammatory). RESULTS: To test the model, we simulated a large number of such networks as in a statistical ensemble. In other words, to enable the inter-cellular crosstalk required to obtain an immune activation in which the macrophage plays its role, the simulated networks are not taken in isolation but combined with other cellular agents, thus setting up a discrete minimalistic model of the immune system at the microscopic/intracellular (i...

BACKGROUND: Autosomal-recessive non-syndromic intellectual disability (ARNS-ID) is an aetiologically heterogeneous disorder. Although little is known about the function of human cereblon (CRBN), its relationship to mild cognitive deficits suggests that it is involved in the basic processes of human memory and learning. OBJECTIVES: We aim to identify the genetic cause of intellectual disability and self-mutilation in a consanguineous Saudi family with five affected members...

BACKGROUND: Self-assessment in nursing education is a ubiquitous tool for developing independent learners and critical thinkers. However, self-assessment may be influenced by both demographic and perceptual factors, making it far more complex than students or instructors realize. METHOD: A demographically heterogeneous group of nursing students (N = 322) was asked to evaluate their performance of a standard clinical procedure-the insertion of a needle into a peripheral vein of an arm simulator; their assessments were compared with those of an instructor...

The vehicle routing problem (VRP) is a widely studied combinatorial optimization problem. We introduce a variant of the multidepot and periodic VRP (MDPVRP) and propose a heuristic initialized stochastic memetic algorithm to solve it. The main challenge in designing such an algorithm for a large combinatorial optimization problem is to avoid premature convergence by maintaining a balance between exploration and exploitation of the search space. We employ intelligent initialization and stochastic learning to address this challenge...
