Is local anesthetic wound infusion following laparotomy effective for colorectal surgery?

A systematic review and meta-analysis found potential benefits of continuous wound infusions of local anaesthetics in reducing opioid consumption after laparotomy for major colorectal surgery. The study highlights the need for future research on this topic, including addressing methodological heterogeneity and cost-effectiveness analysis.

Fires regenerate African grassland

Research in Etosha National Park found periodic fires play a key role in regeneration, breaking up the old grass layer to create opportunities for regrowth. This discovery is significant for managing semi-arid nature reserves where fires are essential for renewing the grass canopy.

Strong association found between prevalence of low white blood count and women of African descent

Researchers at Columbia University's Mailman School of Public Health found a strong association between neutropenia, or low white blood count, and women of African descent. This association may affect disparities in disease treatment and outcomes for cancer therapy, particularly among those with breast and colon cancer.

Political attitudes are predicted by physiological traits

Researchers found that individuals with lower physical sensitivities to sudden noises and threatening images tend to support liberal policies, while those with higher physiological reactions favor conservative policies. This discovery may help explain the stability of strong convictions and the prevalence of political conflict.

Asthma: still more questions than answers

Research has identified distinct pathogenic phenotypes, or endotypes, of asthma that can lead to improved classification and targeted treatment efforts. Additionally, studies have shown associations between paracetamol use in infancy, gene-environment interactions, and the risk of developing inflammatory airway disease.

Breakthrough in spinal injury treatment

Researchers have discovered two types of astrocyte support cells generated from a common stem cell-like precursor cell, one effective at promoting nerve regeneration and the other causing neuropathic pain. The study offers a promising approach to repairing spinal cord injuries without inducing pain syndromes.

New study offers solution to global fisheries collapse

A study finds that catch shares can reverse fisheries collapse, with nearly a third of open-access fisheries collapsing compared to half for those managed under catch share systems. Catch shares create incentives to protect fish populations and reduce bycatch, leading to better biological outcomes.

Plants in forest emit aspirin chemical to deal with stress; discovery may help agriculture

Researchers at the National Center for Atmospheric Research discovered that plants in a forest produce significant amounts of methyl salicylate, a chemical form of aspirin, in response to stress. This finding has the potential to give farmers an early warning signal about crops that are failing.

Expanding cell girth indicates seriousness of breast cancer

Researchers have created a rapid cell inspection technique that can identify metastatic breast cancer cells, which have compromised the cell's structure and compromise deformation. The technique uses an electrical field within a microscopic fluid-filled channel and has been shown to expand cells by 75% in metastatic cases.

Strategies for preventing gastrointestinal complications in severely burned patients

A recent study reviewed clinical data from 219 patients with large area burns to propose guidelines for preventing gastrointestinal dysfunction. Comprehensive fluid resuscitation, early excision of necrotic tissue, staged food ingestion, and administration of specific nutrients were found to be essential strategies in lowering mortality.
