IFI207, a young and fast-evolving protein, controls retroviral replication via the STING pathway.

Mammalian AIM-2-like receptor (ALR) proteins bind nucleic acids and initiate production of type I interferons or inflammasome assembly, thereby contributing to host innate immunity. In mice, the Alr locus is highly polymorphic at the sequence and copy number level, and we show here that it is one of the most dynamic regions of the genome. One rapidly evolving gene within this region, Ifi207, was introduced to the Mus genome by gene conversion or an unequal recombination event a few million years ago. Ifi207 has a large, distinctive repeat region that differs in sequence and length among Mus species and even closely related inbred Mus musculus strains. We show that IFI207 controls murine leukemia virus (MLV) infection in vivo and that it plays a role in the STING-mediated response to cGAMP, dsDNA, DMXXA, and MLV. IFI207 binds to STING, and inclusion of its repeat region appears to stabilize STING protein. The Alr locus and Ifi207 provide a clear example of the evolutionary innovation of gene function, possibly as a result of host-pathogen co-evolution.IMPORTANCEThe Red Queen hypothesis predicts that the arms race between pathogens and the host may accelerate evolution of both sides, and therefore causes higher diversity in virulence factors and immune-related proteins, respectively . The Alr gene family in mice has undergone rapid evolution in the last few million years and includes the creation of two novel members, MndaL and Ifi207. Ifi207, in particular, became highly divergent, with significant genetic changes between highly related inbred mice. IFI207 protein acts in the STING pathway and contributes to anti-retroviral resistance via a novel mechanism. The data show that under the pressure of host-pathogen coevolution in a dynamic locus, gene conversion and recombination between gene family members creates new genes with novel and essential functions that play diverse roles in biological processes.

Administration's Share of Personnel in Veterans Health Administration and Private Sector Care.

Importance: Health care administrative overhead is greater in the US than some other nations but has not been assessed in the Veterans Health Administration (VHA). Objective: To compare administrative staffing patterns in the VHA and private (non-VHA) sectors. Design, Setting, and Participants: This cross-sectional study was conducted using US employment data from 2019, prior to pandemic-related disruptions in health care staffing, and was carried out between January 14 and August 10, 2023. A nationally representative sample of federal and nonfederal personnel in hospitals and ambulatory care settings from the American Community Survey (ACS), all employees reported in VHA personnel records, and personnel in health insurance carriers and brokers tabulated by the Bureau of Labor Statistics (BLS) were analyzed. Exposure: VHA vs private sector health care employment, including 397 occupations grouped into 18 categories. Main Outcome and Measure: The proportion of staff working in administrative occupations. Results: Among 3 239 553 persons surveyed in the ACS, 122 315 individuals (weighted population, 12 501 185 individuals) were civilians working in hospitals or ambulatory care; of the weighted population, 12 156 988 individuals (mean age, 42.6 years [95% CI, 42.5-42.7 years]; 76.2% [95% CI, 75.9%-76.5%] females) were private sector personnel and 344 197 individuals (mean age, 46.2 years [95% CI, 45.7-46.7 years]; 63.8% [95% CI, 61.8%-65.8%] females) were federal employees. In clinical settings, administrative occupations accounted for 23.4% (95% CI, 23.1%-23.8%) of private sector vs 19.8% (95% CI, 18.1%-21.4%) of VHA personnel. After including 1 000 800 employees at private sector health insurers and brokers and 13 956 VHA Central Office personnel with administrative occupations, administration accounted for 3 851 374 of 13 157 788 private sector employees (29.3%) vs 77 500 of 343 721 VHA employees (22.5%). Physicians represented approximately 7% of personnel in the VHA (7.2% [95% CI, 6.1%-8.2%]) and private sector (6.5% [95% CI, 6.3%-6.7%]), while the VHA deployed more registered nurses (23.7% [95% CI, 21.6%-25.8%] vs 21.2% [95% CI, 20.9%-21.5%]) and social service personnel (6.3% [95% CI, 5.4%-7.1%] vs 4.9% [95% CI, 4.7%-5.0%]) than the private sector. Conclusions and Relevance: In this study, administrative occupations accounted for a smaller share of personnel in the VHA compared with private sector care, a difference possibly attributable to the VHA's simpler financing system. These findings suggest that if staffing patterns in the private sector mirrored those of the VHA, nearly 900 000 fewer administrative staff might be needed.

IFI207, a young and fast-evolving antiviral factor, stabilizes STING.

Mammalian ALR proteins bind nucleic acids and initiate production of type I interferons or inflammasome assembly, thereby contributing to host innate immunity. ALR s are encoded at a single genetic locus. In mice, the Alr locus is highly polymorphic at the sequence and copy number level. We suggest that one rapidly evolving member of the Alr family, Ifi207 , was introduced to the Mus genome by a recent recombination event. Ifi207 has a large, distinctive repeat region that differs in sequence and length in different Mus strains. We show that IFI207 plays a key role in the STING-mediated response to cGAMP, DNA, and MLV, and that IFI207 controls MLV infection in vivo. Uniquely, IFI207 acts by stabilizing STING protein via its repeat region. Our studies suggest that under the pressure of host-pathogen coevolution, in a dynamic locus such as the Alr , recombination between gene family members creates new genes with novel and essential functions that play diverse roles in biological processes.

Psychology Internship Training Amidst COVID-19: Balancing Training Opportunities, Patient Care, and Risk of Exposure.

The emergence of the 2019 novel coronavirus (COVID-19) has dramatically altered how psychologists deliver its training. At least for the time being, virtual care has become the primary method for delivering mental health services. This has allowed patients and clinicians to continue to access and provide services in a way that would have been impossible years ago. Not only has this shift impacted patients, but it has also impacted supervision and training. The impact has been especially profound on inpatient units where the psychiatric and medical acuity is high of patients and the therapeutic milieu is an important aspect of treatment. The purpose of this paper is to review the impact of COVID-19 on pre-doctoral psychology interns during their rotation on an inpatient psychiatry unit at the start of the pandemic (January to June of 2020) and use these experiences to onboard the next class of interns in the new academic year (July 2020 to June 2021) using a hybrid model of in-person and virtual training experiences. At the end of 2020/2021 rotation, we voluntarily asked interns to complete a questionnaire that was developed based on the qualitative experiences of the previous class to assess the effectiveness of this hybrid model. We also surveyed multi-disciplinary staff members who were essential personnel and required to work in person during this time about their experiences of safety and support. With this information, we explore and offer guidance to other inpatient training sites who are likely to encounter similar challenges during this time. In particular, we discuss the integration of virtual technology into this training experience, as well as the restructuring of clinical and supervisory experiences. We highlighted several short-term strategies that we have flexibly adapted to our inpatient unit. The lessons learned herein seek to guide supervisors and trainees alike in adapting their psychology training programs to meet the evolving demands of COVID-19.

The Effect of Primary Care Visits on Total Patient Care Cost: Evidence From the Veterans Health Administration.

BACKGROUND: Since the 1980s, primary care (PC) in the US has been recognized as the backbone of healthcare providing comprehensive care to complex patients, coordinating care among specialists, and rendering preventive services to contain costs and improve clinical outcomes. However, the effect of PC visits on total patient care cost has been difficult to quantify. OBJECTIVE: To assess the effect of PC visits on total patient care cost. METHODS: This is a retrospective study of over 5 million patients assigned to a PC provider in the Veterans Health Administration (VHA) in each of the 4 fiscal years (FY 2016-2019). The main outcome of interest is total annual patient care cost. We assessed the effect of primary care visits on total patient care cost first by descriptive statistics, and then by multivariate regressions adjusting for severity of illness and other confounders. We conducted in-depth sensitivity analyses to validate the findings. RESULTS: On average, each additional in-person PC visit was associated with a total cost reduction of $721 (per patient per year). The first PC visit was associated with the largest savings, $3976 on average, and a steady diminishing return was observed. Further, the higher the patient risk (severity of illness), the larger the cost reduction: Among the top 10% of high-risk patients, the first PC in-person visit was associated with a reduction of $16 406 (19%). CONCLUSIONS: These findings, substantiated by our exhaustive sensitivity analyses, suggest that expanding PC capacity can significantly reduce overall health care costs and improve patient care outcomes given the former is a strong proxy of the latter.

Assessing the productivity of PAs and NPs.

ABSTRACT: The improvement of healthcare efficiency and productivity is of international interest. Following an expansion phase of physician associate/assistant (PA) and NPs employment, the Department of Veterans Affairs (VA) assessed how and where they were being used. Using data from 134 VA medical centers, annual productivity was examined across 30 medical and surgical specialties spanning primary care, mental health, and surgery. PA productivity differences averaged 82 relative value units per full-time employee per year more than NPs, a difference of 4%. In general, PAs were found in higher productivity ranges than NP counterparts. PAs and NPs have statistically similar productivity levels in primary care and mental health. In specialty medicine and surgery, PAs average higher annual productivity than NPs. This analysis provides some utility for managers regarding workforce composition, given the relative productivity of two types of clinicians.

Predicting High-risk and High-cost Patients for Proactive Intervention.

BACKGROUND: It is well known that 20% of the patients incur 80% of health care costs and many diseases and complications can be prevented or ameliorated with prompt intervention. One of the well-recognized strategies for cost reduction and better outcomes is to predict or identify high-risk and high-cost (HRHC) patients for proactive intervention. OBJECTIVE: The objective of this study was to develop a predictive model that can be used to identify HRHC patients more accurately for proactive intervention. METHODS: This is an observational study using fiscal year (FY) 2018 administrative data to predict FY 2019 total cost at the patient level. All 5,676,248 patients who received care in both FYs 2018 and 2019 from the Veterans Health Administration were included in the analyses. The Veterans Health Administration Corporate Data Warehouse was our main data source. With split-sample analyses, 3 sets of patient comorbidities and 5 statistical models were assessed for the highest predictive power. RESULTS: The Box-Cox regression using comorbidities designated by the expanded CCSR (Clinical Classifications Software Refined) groups as predictors yielded the highest predictive power. The R2 reached 0.51 and 0.37 for the transformed and raw scale cost, respectively. CONCLUSIONS: The predictive model developed in this study exhibits substantially higher predictive power than what has been reported in the literature. The algorithm based on administrative data and a publicly available patient classification system can be readily implemented by other value-based health systems to identify HRHC patients for proactive intervention.

Characteristics and productivity of the chiropractic workforce of the Veterans Health Administration.

BACKGROUND: Increasingly, integrated healthcare systems such as the United States Veterans Health Administration (VHA) are employing chiropractors. However, little is known about chiropractor employee clinical productivity which may be important for resource planning and monitoring care delivery. With its history of delivering chiropractic care and its enterprise-level assessment metrics, the VHA is an ideal setting to study a chiropractic workforce. We aim to assess characteristics of chiropractors employed by the VHA and explore associations between these characteristics and clinical productivity. METHODS: This was a cross-sectional and serial analyses of VHA administrative data. Characteristics of the chiropractor workforce were evaluated from fiscal year (FY) 2016 to FY2019. Productivity was calculated using the VHA productivity measure, the quotient of an individual's total work relative value units (wRVUs) per FY divided by the direct clinical full-time equivalent (FTE) worked. A multivariable regression model was used to analyze the association between productivity and characteristics of the chiropractor and VHA facility. RESULTS: From FY2016 to FY2019, the number of chiropractor employees increased from 102 to 167. In FY2019, the typical chiropractor employee was male, white, and 45.9 years old with 5.2 years of VHA experience. In FY2019, the VHA chiropractor workforce was 25.1% female, 79% white, and 20.4% Veteran. The productivity measure of a chiropractor was 3040 in FY2019. A higher facility complexity measure, presence of 3 chiropractor employees at a facility, and older age of the providers were the only characteristics studied that had a significant impact on productivity after adjusting for other covariates. CONCLUSION: Provider characteristics and productivity metrics of the VHA chiropractor employee workforce are presented. The productivity measure provides an initial benchmarking that may be relevant to future modeling of chiropractor personnel in VHA and other healthcare systems.

Primary Care's Effects on Costs in the US Veterans Health Administration, 2016-2019: an Observational Cohort Study.

BACKGROUND: Enhancing primary care is a promising strategy for improving the efficiency of health care. Previous studies of primary care's effects on health expenditures have mostly relied on ecological analyses comparing region-wide expenditures rather than spending for individual patients. OBJECTIVE: To compare overall medical expenditures for individual patients enrolled vs. those not enrolled in primary care in the Veterans Health Administration (VHA). DESIGN: Cohort study with stratification for clinical risk and multivariable linear regression models adjusted for clinical and demographic confounders of expenditures. PARTICIPANTS: In total, 6,009,973 VHA patients in fiscal year (FY) 2019-5,410,034 enrolled with a primary care provider (PCP) and 599,939 without a PCP-and similar numbers in FYs 2016-2018. MAIN MEASURES: Total annual cost per patient to the VHA (including VHA payments to non-VHA providers) stratified by a composite health risk score previously shown to predict VHA expenditures, and multivariate models additionally adjusted for VHA regional differences, patients' demographic characteristics, non-VHA insurance coverage, and driving time to the nearest VHA facility. Sensitivity analyses explored different modeling strategies and risk adjusters, as well as the inclusion of expenditures by the Medicare program that covers virtually all elderly VHA patients for care not paid for by the VHA. KEY RESULTS: Within each health-risk decile, non-PCP patients had higher outpatient, inpatient, and total costs than those with a PCP. After adjustment for health risk and other factors, lack of a PCP was associated 27.4% higher VHA expenditures, $3274 per patient annually (p < .0001). Sensitivity analyses using different risk adjusters and including Medicare's spending for VHA patients yielded similar results. CONCLUSIONS: In the VHA system, primary care is associated with substantial cost savings. Investments in primary care in other settings might also be cost-effective.

New Razor Technology Improves Appearance and Quality of Life in Men With Pseudofolliculitis Barbae.

Pseudofolliculitis barbae (PFB) consists of ingrown hairs leading to papules, pustules, and discomfort. This prospective, 12-week clinical study aimed to assess the appearance of males with razor bumps and shaving irritation when using a new razor technology with 2 blades separated by a bridge feature (SkinGuard [Procter & Gamble]). The impact on participants' shave-related itching, burning, and stinging severity, as well as quality of life (QOL), also was assessed. In men with PFB, shaving with the test razor at least 5 times per week over a 12-week period improved the appearance and QOL of males with razor bumps and shaving irritation compared with baseline.
