Mental Health Carve-Outs: Effects and Implications

To control the rise in expenditures and to increase access to mental health and substance abuse (MH/SA) services, a growing number of employers and states are implementing a “carve-out.” Under this arrangement, the sponsor separates insurance benefits by disease or condition, service category, or population and contracts separately for the management of care and/or associated risks. A carve-out allows a unique set of managed care techniques to be applied to a subset of particularly costly or complex benefits. This article describes various carve-out models, discusses the potential advantages and disadvantages of a full carve-out, and summarizes recent public and private sector research regarding the strategy’s effects on access and use, cost savings and shifting, and quality of care. It concludes by discussing approaches to the assessment and monitoring of the processes and outcomes associated with a MH/SA carve-out.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68797/2/10.1177_107755879905600203.pd

Impact of inactivity and exercise on the vasculature in humans

The effects of inactivity and exercise training on established and novel cardiovascular risk factors are relatively modest and do not account for the impact of inactivity and exercise on vascular risk. We examine evidence that inactivity and exercise have direct effects on both vasculature function and structure in humans. Physical deconditioning is associated with enhanced vasoconstrictor tone and has profound and rapid effects on arterial remodelling in both large and smaller arteries. Evidence for an effect of deconditioning on vasodilator function is less consistent. Studies of the impact of exercise training suggest that both functional and structural remodelling adaptations occur and that the magnitude and time-course of these changes depends upon training duration and intensity and the vessel beds involved. Inactivity and exercise have direct “vascular deconditioning and conditioning” effects which likely modify cardiovascular risk

Respostas cardio-respiratórias em pacientes com traumatismo raquimedular Cardiorespiratory responses of patients with spinal cord injuries

O objetivo desta pesquisa foi investigar as variáveis cardio-respiratórias (Pa, FC, VO2, VCO2 e Ve) durante a Estimulação Elétrica Neuromuscular (EENM) do quadríceps em portadores de lesão medular. Participaram da pesquisa dez pacientes (cinco paraplégicos e cinco tetraplégicos). O protocolo do teste consistiu em 10 minutos de repouso, 20 minutos de EENM dos quadriceps e 10 minutos de recuperação. Durante a EENM foram constatados baixos valores de VO2 e VCO2. Os paraplégicos apresentaram rápida cinética dos gases e os tetraplégicos lenta cinética dos gases. Houve o aumento da Pa sistólica e da FC. Ainda, os valores das variáveis cardio-respiratórias foram inversamente relatadas para o nível de lesão, ou seja, quanto maior o nível de lesão, menor os valores. Portanto, a maioria dos pacientes apresentaram algumas limitações nas respostas cardio-respiratórias, indicando realização de exercício exaustivo, mas apresentaram capacidade de realização de exercício induzido artificialmente, possivelmente devido aos benefícios da EENM.<br>The objective of this study was to investigate cardiorespiratory responses (Heart Rate, Blood Pressure, VO2, VCO2 e Ve) to Neuromuscular Electrical Stimulation (NMES) of the quadriceps in patients with spinal cord injury. Ten patients (five paraplegics and five tetraplegics) participated in this study. The protocol of the test consisted of ten minutes of rest, twenty minutes of NMES of the quadriceps and ten minutes of recovery. The findings in this study indicated that, during NMES, the patients demonstrated low levels of VO2 and VCO2 and slow gas kinetics for tetraplegic individuals, and a fast gas kinetics for paraplegic individuals. Moreover, there were increases in blood pressure and heart rate. Cardiorespiratory responses increased with descending spinal cord injury level, meaning that the more severe the lesion, the lower the values. Therefore, most of the patients presented some limitations in cardiorespiratory responses, indicating the performance of exhaustive exercise, but the use of NMES can elicit improvements in exercise tolerance due to its benefits
