Decreases in body sizes of animals related to recent climate warming can affect population persistence and stability. However, direct observations of average sizes over time and their interrelationships with underlying density-dependent and density-independent processes remain poorly understood owing to the lack of appropriate long-term datasets. We measured body size of two species common to headwater streams in coastal and Cascades ecoregions of the Pacific Northwest of North America over multiple decades, comparing old-growth and managed forests.

Introduction: Fifty years ago, basic scientific studies and the availability of assay methods made the assessment of risk in paracetamol (acetaminophen) poisoning possible. The use of the antidote acetylcysteine linked to new methods of risk assessment transformed the treatment of this poisoning. This review will describe the way in which risk assessment and treatments have developed over the last 50 years and highlight the remaining areas of uncertainty.

Schizophrenia is associated with early mortality of 15 to 20 years, and 80 % of deaths are due to cardiovascular disease with a three-times greater risk of sudden-cardiac-death. While lifestyle, medications, genetics, and healthcare disparities are contributing factors, the etiology of this complex process is not fully understood. The aim of this study is to examine cardiac-related healthcare utilization and electrocardiogram (ECG) outcomes in schizophrenia at the end of life (EOL).

Introduction: Acetylcysteine is the only effective and licensed therapy for paracetamol poisoning. However, acetylcysteine loses efficacy if treatment is delayed 8-12 hours after paracetamol ingestion, and there is also uncertainty as to whether the dose should be increased in high-risk paracetamol ingestions. Studies have identified potential therapeutic targets, including enzymes that metabolize paracetamol; the pathways causing mitochondrial toxicity c-Jun N-terminal kinases or superoxide generation; and other specific targets, such as nuclear factor-erythroid factor 2-dependent gene induction and autophagy.

Quinine has been used in Western medicine since the 16th century, and far longer in South America. It has gained an undeserved reputation as an effective treatment for leg cramps and continues to be widely used in the United Kingdom and elsewhere despite warnings from the Medicines and Healthcare products Regulatory Agency (MHRA) and the US Food and Drug Administration (FDA). The effects in overdose are outlined and a personal perspective of scientific investigation of treatments at one time advocated provided.

Preterm birth results in low nephron endowment and increased risk of acute kidney injury (AKI) and chronic kidney disease (CKD). To understand the pathogenesis of AKI and CKD in preterm humans, we generated potentially novel mouse models with a 30%-70% reduction in nephron number by inhibiting or deleting Ret tyrosine kinase in the developing ureteric bud. These mice developed glomerular and tubular hypertrophy, followed by the transition to CKD, recapitulating the renal pathological changes seen in humans born preterm.

Introduction: Enemas containing phosphate are widely prescribed and may cause important adverse effects. A systemic review published in 2007 reported the literature on the adverse effects of phosphate enemas from January 1957 to March 2007 and identified 12 deaths. These were thought due to electrolyte disturbances, heart failure and kidney injury.

Background/methods: Lumbar puncture CSF pressure measurements in a large group of adults (116) having lumbar puncture (LP) for diagnostic reasons with no clinical indication of raised intracranial pressure were used to establish the normal range of CSF pressure. The cerebrospinal fluid (CSF) pressure was also measured in a smaller unselected series of patients (35) with the syndrome of idiopathic intracranial hypertension (IIH). All the lumbar punctures were performed by the same highly skilled operator, a consultant nurse, to ensure accuracy of measurement.

Contrast-induced nephropathy (CIN) is a major complication of imaging in patients with chronic kidney disease (CKD). The publication of an academic randomized controlled trial (RCT; n = 83) reporting oral (N)-acetylcysteine (NAC) to reduce CIN led to > 70 clinical trials, 23 systematic reviews, and 2 large RCTs showing no benefit. However, no mechanistic studies were conducted to determine how NAC might work; proposed mechanisms included renal artery vasodilatation and antioxidant boosting.

Paracetamol poisoning continues to be a worldwide problem and, despite the availability of an effective antidote, acetylcysteine (NAC), the optimal way to use this antidote, particularly following very large doses of paracetamol, has not been established. Recent case series have shown an increased toxicity from high doses of paracetamol, even in those receiving prompt NAC therapy, particularly in patients above the 300 mg/L nomogram treatment line. Clinical trial evidence supporting shorter NAC dosing now allows the possibility for intensifying treatment without the risk of very high rates of ADRs.

Focal cortical dysplasia (FCD) is one of the most common malformations causing refractory epilepsy. Dysregulation of glutamatergic systems plays a critical role in the hyperexcitability of dysplastic neurons in FCD lesions. The pharmacoresistant nature of epilepsy associated with FCD may be due to a lack of well-tolerated and precise antiepileptic drugs that can target glutamate receptors.
