Trends in Postacute Care Spending Growth During the Medicare Spending Slowdown

Laura M. Keohane, Salama Freed, David G. Stevenson, Sunita Thapa, Lucas Stewart & Melinda B. Buntin
ABSTRACT Issue: Over the past decade, traditional Medicare’s per-beneficiary spending grew at historically low levels. To understand this phenomenon, it is important to examine trends in postacute care, which experienced exceptionally high spending growth in prior decades. Goal: Describe per-beneficiary spending trends between 2007 and 2015 for postacute care services among traditional Medicare beneficiaries age 65 and older. Methods: Trend analysis of individual-level Medicare administrative data to generate per-beneficiary spending and utilization estimates for postacute...

How ACOs Are Caring for People with Complex Needs

Kristen A. Peck, Benjamin Usadi, Alexander Mainor, Helen Newton & Ellen Meara
ABSTRACT Issue: With an incentive to provide high-quality care while controlling costs, accountable care organizations (ACOs) may focus on patients who require the most resources and are most at risk for encountering serious problems with their care. Understanding how ACOs approach care for complex patients requires examination of their organizational strategies, contracting details, and leadership structures. Goals: Describe the specific strategies employed by ACOs that have comprehensive care management programs and processes for complex patients....

Court Decision to Invalidate the Affordable Care Act Would Affect Every American

Timothy S. Jost
Texas federal court Judge Reed O’Connor delivered a judgment, in the Texas v. Azar case, invalidating the Affordable Care Act. According to legal expert Timothy S. Jost, the decision will be appealed and likely blocked from going into effect.

The Time Is Now: The Case for Digital Health Innovation for the Poor and Underserved

Lisa Fitzpatrick
Few resources are accessible to people with low incomes, who might stand to benefit from them most. Health care regulations restricting payment for new technologies could be a reason for this access gap. But another is lack of insight among funders, developers, and health care innovation leaders into poor Americans’ access to mobile phones and the Internet, or these patients’ interest in using technology for health care needs. It has been unclear to these groups...

The future of public sector forecasting in Australian agriculture

The operating context of Australian agriculture has changed dramatically since Australian governments first committed to providing forecasting services for agriculture in the 1940s. This paper explores the evolution of these forecasting services, how the world has changed since then, and what this means for the future design of these services.

Information and communication technology use in Australian agriculture

& Thomas Jackson
New information and communications technology (ICT) could deliver the next wave of productivity growth in Australian agriculture. ICT includes all digital technologies that facilitate the electronic capture, processing, storage and exchange of information. To better understand the role of ICT in Australian agriculture and potential barriers to its use, ABARES surveyed over 2,200 farmers in 2016–17. Results from this survey are presented here for broadacre, dairy and vegetable farms.

After the ACA Simplified Medicaid Enrollment, the Administration and Some States Are Making It Far More Complicated

Sara Rosenbaum, Maria Velasquez, Sara Rothenberg & Rachel Gunsalus
For years, the federal government and states have sought to get rid of enrollment barriers in Medicaid. Now a number of states are reversing course: 14 states have approved or pending Medicaid 1115 demonstrations designed to restrict Medicaid eligibility. Attention has focused on the demonstrations’ work mandates, but the experiments involve much more. Other features include extensive reporting rules — in some proposals enrollees must report on their eligibility status weekly — as well as...

GFPnovo2, a brighter GFP variant for in vivo labeling in C. elegans

Ardalan Hendi & Kota Mizumoto
Green fluorescent protein (GFP) is one of the most common fluorophores used to label cells and proteins in C. elegans. Previous artificial protein evolution strategy has generated a variant of eGFP, GFPnovo2, which is 3.3 times brighter than the original eGFP in the DT40 cell line (Arakawa et al, 2008). GFPnovo2 carries four mutations from the original eGFP (Y145F, V163A, S202T, L221V), and has the same excitation/emission wavelengths as the original eGFP. Here we compared...

Immunofluorescence reveals neuron-specific promoter activity in non-neuronal cells

Sierra K. Lear, Alakananda Das & Miriam B. Goodman
Four transgenes designed to drive expression of Cre recombinase and a nuclear-localized blue fluorescent protein (::Cre::F2A::BFP::NLS::tbb-2 3'UTR) were expressed under the control of neuron-specific promoters. All transgenes were inserted into the ttTi5605 transposon insertion site in chromosome II of wild-type C. elegans animals (N2) using CRISPR/Cas9-mediated genome editing, equalizing any potential positional effects. We observed very faint BFP signal in live worms from the signal copy transgene insertions. Additionally, the signal was further masked by...

Silencing the ASI gustatory neuron pair increases expression of the stress-resistance gene sod-3 in a daf-16 and daf-3 independent manner

Peter Chisnell & Cynthia Kenyon
Ablation of the gustatory neuron pair ASI has been shown to extend lifespan, and this lifespan extension requires the function of the transcription factor daf-16/FOXO (Alcedo and Kenyon 2004). Given this relationship, we tested whether silencing the neuron pair ASI with the tetanus toxin light chain (Tetx), as opposed to ablating it, could increase the expression of a well- known DAF-16 target, the stress-resistance gene sod-3 (Furuyama et al. 2000; Honda and Honda 1999). Tetanus...

New allele of C. elegans gene spch-3 (T27A3.4), called xc2

Nicholas R. Munoz, Dana T. Byrd & Diana Chu
We created a new mutant allele, named xc2, of the gene spch-3 (T27A3.4). spch-3 encodes one of three C. elegans small, highly basic proteins that resemble invertebrate protamines and associate with sperm meiotic chromosomes (Chu et al., 2006). The alleles were isolated from gene mutations generated by Non-Homologous End Joining (NHEJ) mediated repair of Cas9-generated breaks (Dickinson et al., 2013; Ran et al., 2013). The alleles were discovered using PCR with the following primers 5’-...

Immobilization nematodes for live imaging using an agarose pad produced with a Vinyl Record

Katherine A. Rivera Gomez & Mara Schvarzstein
Numerous microfluidic systems have been developed and used for live imaging of Caenorhabditis nematodes (Allen et al., 2008; Zhang et al., 2008; Krajniak and Lu, 2010; Krajniak et al., 2013; Cornaglia et al., 2015). These systems can be costly, complex to set up, or require high-maintenance between uses. In addition, microfluidic rigs can be thick, preventing live imaging of worms from strains expressing low fluorescence fusion proteins. In the absence of elaborate microfluidic rigs, most...

A C. elegans model for the rare human channelopathy, Timothy syndrome type 1.

Ross C. Lagoy, Heesun Kim, Craig C. Mello & Dirk R. Albrecht
Timothy syndrome (TS) type 1 is a rare genetic human disease caused by a gain-of-function (GOF) missense mutation G406R in the L-type voltage-gated calcium channel (VGCC) α1 subunit gene CACNA1C, which results in severe cardiac arrhythmia and autism (Splawski et al. 2004). The C. elegans ortholog is EGL-19 (Fig. 1a), which is expressed in muscle and neurons (Lee et al. 1997). GOF mutations in egl-19 cause myotonic phenotypes, while reduction-of-function (ROF) mutants are flaccid, variably...

Raman active modes of single-wall boron nitride nanotubes inside carbon nanotubes

A.M. Nassir, AH. Rahmani, M. Boutahir, B. Fakrach, H. Chadli & A. Rahmani
The structure of boron–nitride nanotubes (BNNTs) is very similar to that of CNTs, and they exhibit many similar physical and chemical properties. In particular, a single walled boron nitride nanotube (BNNT) and a single walled carbon nanotube (CNT) have been reported. The spectral moment’s method (SMM) was shown to be a powerful tool for determining vibrational spectra (infrared absorption, Raman scattering and inelastic neutron- scattering spectra) of harmonic systems. This method can be applied to...

The post-embryonic development of Amphiprion perideraion reveals a decoupling between morphological and pigmentation change

Pauline Salis, Natacha Roux, David Lecchini & Vincent Laudet
During coral reef fish life cycle, the young pelagic larvae colonize the reef. During such important ecological transition, larvae undergo metamorphosis consisting on important morphological, colour, physiological and behavioural changes. We investigated the post-embryonic development of Amphiprion perideraion Bleeker, 1855 larvae raised in captivity from 1 day post-hatching (dph) until 20 dph. To do so, we characterized larval growth, morphological changes and pigmentation ontogenesis. Interestingly, whereas most of the morphological changes are done from 3...
