Long-Term Cellulose Enrichment Selects for Highly Cellulolytic Consortia and Competition for Public Goods.

The complexity of microbial communities hinders our understanding of how microbial diversity and microbe-microbe interactions impact community functions. Here, using six independent communities originating from the refuse dumps of leaf-cutter ants and enriched using the plant polymer cellulose as the sole source of carbon, we examine how changes in bacterial diversity and interactions impact plant biomass decomposition. Over up to 60 serial transfers (∼8 months) using Whatman cellulose filter paper, cellulolytic ability increased and then stabilized in four enrichment lines and was variable in two lines.

Joint-Venture Ambulatory Surgery Centers: The Perfect Partnership.

Background: Ambulatory surgery growth has increased in the last few decades as ambulatory surgery centers have been shown to succeed in cost efficiencies through their smaller size and breadth, specialization of care, and ability to quickly participate in perioperative process improvement and education.

Methods: A 5-year retrospective fiscal review was performed for all Northwell Health-physician ambulatory surgery center joint ventures. The outcome measures studied included model of ownership, specialty types, and gross revenue.

A Feasibility Study of Primary Care Liaisons: Linking Older Adults to Community Resources.

Introduction: Programs and services available through the aging services network can help community-dwelling older adults to age in place but are often not discussed in routine primary care. The primary care liaison was developed as a novel integration intervention to address this disconnect.

Methods: Employed by an Area Agency on Aging, primary care liaisons performed outreach to primary care with the goal of raising awareness of community-based programs, resources, and services available to older adults and their caregivers and facilitating referrals.

Editor's Choice - Nationwide Analysis of Patients Undergoing Iliac Artery Aneurysm Repair in the Netherlands.

Objective: The new 2019 guideline of the European Society for Vascular Surgery (ESVS) recommends consideration for elective iliac artery aneurysm (eIAA) repair when the iliac diameter exceeds 3.5 cm, as opposed to 3.0 cm previously.

Effects of physical exercise programs on cognitive function in Parkinson's disease patients: A systematic review of randomized controlled trials of the last 10 years.

Background: Given the relative importance of cognitive impairment, there was considerable interest in identifying the cognitive profile of PD patients, in order to ensure specific and appropriate therapeutic interventions.

Purpose: To determine the effects of physical exercise programs on cognitive function in PD patients, compared with the control group.
