TL;DR: Taken together, research suggests that menopause is associated with lower gut microbiome diversity and a shift toward greater similarity to the male gut microbiome, however more research is needed in large study populations to identify replicable patterns in taxa impacted byMenopause.
Abstract: Abstract The gut microbiome is an important contributor to human health, shaped by many endogenous and exogenous factors. The gut microbiome displays sexual dimorphism, suggesting influence of sex hormones, and also has been shown to change with aging. Yet, little is known regarding the influence of menopause – a pivotal event of reproductive aging in women – on the gut microbiome. Here, we summarize what is known regarding the interrelationships of female sex hormones and the gut microbiome, and review the available literature on menopause, female sex hormones, and the gut microbiome in humans. Taken together, research suggests that menopause is associated with lower gut microbiome diversity and a shift toward greater similarity to the male gut microbiome, however more research is needed in large study populations to identify replicable patterns in taxa impacted by menopause. Many gaps in knowledge remain, including the role the gut microbiome may play in menopause-related disease risks, and whether menopausal hormone therapy modifies menopause-related change in the gut microbiome. Given the modifiable nature of the gut microbiome, better understanding of its role in menopause-related health will be critical to identify novel opportunities for improvement of peri- and post-menopausal health and well-being.

TL;DR: It is found that billing and insurance-related costs for inpatient bills range from a low of $6 in Canada to a high of $215 in the US for an inpatient surgical bill (purchasing power parity adjusted), which illustrates a valuable pathway for future research in understanding and mitigating administrative costs in health care.
Abstract: Billing and insurance-related costs are a significant source of wasteful health care spending in Organization for Economic Cooperation and Development nations, but these administrative burdens vary across national systems. We executed a microlevel accounting of these costs in different national settings at six provider locations in five nations (Australia, Canada, Germany, the Netherlands, and Singapore) that supplements our prior study measuring the costs in the US. We found that billing and insurance-related costs for inpatient bills range from a low of $6 in Canada to a high of $215 in the US for an inpatient surgical bill (purchasing power parity adjusted). We created a taxonomy of billing and insurance-related activities (eligibility, coding, submission, and rework) that was applied to data from the six sites and allows cross-national comparisons. Higher costs in the US and Australia are attributed to high coding costs. Much of the savings achieved in some nations is attributable to assigning tasks to people in lower-skill job categories, although most of the savings are due to more efficient billing and insurance-related processes. Some nations also reduce these costs by offering financial counseling to patients before treatment. Our microlevel approach can identify specific cost drivers and reveal national billing features that reduce coding costs. It illustrates a valuable pathway for future research in understanding and mitigating administrative costs in health care.

TL;DR: Although past psychological problems and current depression and PTSD were associated with difficulty maintaining sleep, the main association remained robust also after controlling for those conditions in the full model.
Abstract: Objective To identify COVID-19 work-related stressors and experiences associated with sleep difficulties in HCW, and to assess the role of depression and traumatic stress in this association. Methods A cross-sectional study of HCW using self-report questionnaires, during the first peak of the pandemic in Israel (April 2020), conducted in a large tertiary medical center in Israel. Study population included 189 physicians and nurses working in designated COVID-19 wards and a comparison group of 643 HCW. Mean age of the total sample was 41.7 ± 11.1, 67% were female, 42.1% physicians, with overall mean number of years of professional experience 14.2 ± 20. The exposure was working in COVID-19 wards and related specific stressors and negative experiences. Primary outcome measurement was the Insomnia Severity Index (ISI). Secondary outcomes included the Primary Care-Post Traumatic Stress Disorder Screen (PC-PTSD-5); the Patient Health Questionnaire-9 (PHQ-9) for depression; the anxiety module of the Patient-Reported Outcomes Measurement Information System (PROMIS); Pandemic-Related Stress Factors (PRSF) and witnessing patient suffering and death. Results Compared with non-COVID-19 HCW, COVID-19 HCW were more likely to be male (41.3% vs. 30.7%) and younger (36.91 ± 8.81 vs. 43.14 ± 11.35 years). COVID-19 HCW reported higher prevalence of sleep difficulties: 63% vs. 50.7% in the non-COVID group (OR 1.62, 95% CI 1.15–2.29, p = 0.006), mostly difficulty maintaining sleep: 26.5% vs. 18.5% (OR 1.65, 95% CI 1.11–2.44, p = 0.012). Negative COVID-19 work-related experiences, specifically witnessing patient physical suffering and death, partially explained the association. Although past psychological problems and current depression and PTSD were associated with difficulty maintaining sleep, the main association remained robust also after controlling for those conditions in the full model. Conclusion and Relevance COVID-19 frontline HCW were more likely to report sleep difficulties, mainly difficulty maintaining sleep, as compared with non-COVID-19 HCW working at the same hospital. Negative patient-care related experiences likely mediated the increased probability for those difficulties. Future research is needed to elucidate the long-term trajectories of sleep difficulties among HCW during large scale outbreaks, and to identify risk factors for their persistence.

TL;DR: In this paper , the authors use a health care application to illustrate how variance analysis can be used to benchmark costs across similar service delivery sites using time-driven activity-based costing.
Abstract: We use a health care application to illustrate how variance analysis can be used to benchmark costs across similar service delivery sites. Variances for personnel costs, typically the largest cost component in service organizations, are calculated for price, quantity, and skill mix components. Skill mix is important since employees with different compensation often work together to produce service outputs. We find that the joint variance, which arises when both prices and quantities differ, has more managerial implications when assigned to the quantity variance, rather than its traditional allocation to the price variance. Using time-driven activity-based costing also leads to a new variance that reflects the impact of personnel capacity differences between sites. Finally, we introduce two new visualization tools to display the variances. Educators can teach students how variance analysis reveals opportunities to reduce personnel costs by identifying and transferring best practices across sites.

TL;DR: This work suggests incorporating the appreciation of four desiderata of explainability into early-stage research that designs and tests brain aging technology, and believes this novel approach will promote the development and adoption of brain agingtechnology that links and addresses brain pathophysiology and functional independence in the field of translational research.
Abstract: Brain aging leads to difficulties in functional independence. Mitigating these difficulties can benefit from technology that predicts, monitors, and modifies brain aging. Translational research prioritizes solutions that can be causally linked to specific pathophysiologies at the same time as demonstrating improvements in impactful real-world outcome measures. This poses a challenge for brain aging technology that needs to address the tension between mechanism-driven precision and clinical relevance. In the current opinion, by synthesizing emerging mechanistic, translational, and clinical research-related frameworks, and our own development of technology-driven brain aging research, we suggest incorporating the appreciation of four desiderata (causality, informativeness, transferability, and fairness) of explainability into early-stage research that designs and tests brain aging technology. We apply a series of work on electrocardiography-based "peripheral" neuroplasticity markers from our work as an illustration of our proposed approach. We believe this novel approach will promote the development and adoption of brain aging technology that links and addresses brain pathophysiology and functional independence in the field of translational research.

TL;DR: This study demonstrates how time-driven activity-based costing may be used in ICU administration to quantify the savings that 1 US hospital could achieve by delivering the same quality of care with fewer and less-costly mix of clinicians compared to a French and Australian site.
Abstract: The United States spends more for intensive care units (ICUs) than do other high-income countries. We used time-driven activity-based costing (TDABC) to analyze ICU costs for initiation of veno-venous extracorporeal membrane oxygenation (VV ECMO) for respiratory failure to estimate how much of the higher ICU costs at 1 US site can be attributed to the higher prices paid to ICU personnel, and how much is caused by the US site’s use of a higher cost staffing model. We accompanied our TDABC approach with narrative review of the ECMO programs, at Cedars-Sinai (Los Angeles), Hôpital Pitié-Salpêtrière (Paris), and The Alfred Hospital (Melbourne) from 2017 to 2019. Our primary outcome was daily ECMO cost, and we hypothesized that cost differences among the hospitals could be explained by the efficiencies and skill mix of involved clinicians and prices paid for personnel, equipment, and consumables. Our results are presented relative to Los Angeles’ total personnel cost per VV ECMO patient day, indexed at 100. Los Angeles’ total indexed daily cost of care was 147 (personnel: 100, durables: 5, and disposables: 42). Paris’ total cost was 39 (26% of Los Angeles) (personnel: 12, durables: 1, and disposables: 26). Melbourne’s total cost was 53 (36% of Los Angeles) (personnel: 32, durables: 2, and disposables: 19) (rounded). The higher personnel prices at Los Angeles explained only 26% of its much higher personnel costs than Paris, and 21% relative to Melbourne. Los Angeles’ higher staffing levels accounted for 49% (36%), and its costlier mix of personnel accounted for 12% (10%) of its higher personnel costs relative to Paris (Melbourne). Unadjusted discharge rates for ECMO patients were 46% in Los Angeles (46%), 56% in Paris, and 52% in Melbourne. We found that personnel salaries explained only 30% of the higher personnel costs at 1 Los Angeles hospital. Most of the cost differential was caused by personnel staffing intensity and mix. This study demonstrates how TDABC may be used in ICU administration to quantify the savings that 1 US hospital could achieve by delivering the same quality of care with fewer and less-costly mix of clinicians compared to a French and Australian site. Narrative reviews contextualized how the care models evolved at each site and helped identify potential barriers to change.

TL;DR: The DSM-III nomenklatura of American psychiatry follow a befruitful-and-multiply approach, with every edition of the DSM proffering a dazzling array of new conditions as mentioned in this paper .
Abstract: What is a psychiatric disorder? How do you distinguish madness from normal behaviour? The nomenklatura of American psychiatry follow a befruitful-and-multiply approach, with every edition of the DSM – the Diagnostic and Statistical Manual – proffering a dazzling array of new conditions. Where these disorders arise is a matter of contentious debate with a strong school of thought contending that they emerge, not from decades of careful clinical observation, but the exigencies of an organising committee with its accompanying politics. This is hardly a good way for a behavioural science to progress, but unwittingly perpetuates a postmodern trope where truth is a dubious entity.

TL;DR: This editorial summarizes the Defense Health Board's (DHB) review of Active Duty Women's Health and its recommendations grounded in a woman's career life-cycle, finding employers can learn how to reduce morbidity, leading to a healthier and more productive female workforce.
Abstract: Women comprise an increasing percentage of U.S. military personnel. The Department of Defense (DoD) recognizes that women's health requires attention to workplace design, physical standards for entry, employment practices, equipment, and health monitoring. The DoD approach offers lessons for civilian employers in traditionally male-dominant fields. Objective: Women's health has demanded more attention from employers as women integrated into the workforce. Traditionally male-dominant fields and occupations require special attention to workplace design, physical standards for entry, employment practices, equipment, and health monitoring. This editorial summarizes the Defense Health Board's (DHB) review of Active Duty Women's Health and its recommendations grounded in a woman's career life-cycle. Methods: The DHB reviewed the Department of Defense and foreign militaries’ current women's health services, relevant policies and practices, peer-reviewed scientific literature, and subject matter expert interviews. Results: The DHB's recommendations centered on a comprehensive approach to education, health care access and treatment, professional workforce development, workplace standards and equipment, and accountable outcomes metrics to guide improvement. Conclusions: Employers can learn how to reduce morbidity, leading to a healthier and more productive female workforce.

TL;DR: Virtual visits for postoperative care of patients undergoing shoulder surgery are associated with decreased costs and high ratings of convenience and satisfaction, and postoperative complications may be more challenging to diagnose virtually.
Abstract: Introduction: Studies comparing the cost of in-person and virtual care are lacking. The goal of this study was threefold (1) to compare the cost of telemedicine visits with in-person clinic visits after common shoulder surgeries, (2) to measure the safety, and (3) to evaluate patient experience with telemedicine visits. Methods: The In-Person Visit cohort (N = 25) and the telemedicine cohort (Virtual Visit cohort, N = 24) were selected from patients undergoing routine follow-up of common shoulder procedures. Time-driven activity-based costing was used to determine costs associated with each episode of care. Patient complications, satisfaction, convenience, and technical difficulties associated with telehealth were recorded. Results: The average Virtual Visit was 54.1% less costly and 87.8% shorter than the In-Person Visit ($49 versus $107 per patient, 8.6 versus 70.1 minutes per patient, P < 0.01, respectively). One complication was missed in the Virtual Visit cohort, later captured by an in-person visit. All patients in the Virtual Visit cohort reported that the virtual visit was safe and convenient and showed high levels of satisfaction. Discussion: Virtual visits for postoperative care of patients undergoing shoulder surgery are associated with decreased costs and high ratings of convenience and satisfaction. Postoperative complications may be more challenging to diagnose virtually.

TL;DR: In this article , a team-based collaborative model was used in a small physician practice in Osseo, Wisconsin, where medical assistants/licensed practical nurses (MA/LPN) were partner with primary care physicians during a patient visit.
Abstract: BACKGROUND Primary care physicians are overburdened with growing complexities and increasing expectations for primary care visits. To meet expectations, primary care physicians must multitask during visits and spend extra hours in the office for charting, billing, and documentation. This impacts the physician's quality of life and may affect the quality of patient care. Many of the administrative tasks performed by physicians could, alternatively, be performed by nonphysician staff, leading to the adoption of team-based collaborative models. METHODS Mayo Clinic Health System piloted a team-based collaborative model in a small physician practice in Osseo, Wisconsin, where which staff could be trained quickly and efficiently. The model used medical assistants/licensed practical nurses (MA/LPN) to partner with primary care physicians during a patient visit. The LPN/MA, under physician supervision, ordered and monitored pending orders/labs, coordinated patient care, provided after-visit educational needs, and communicated other urgent messages to team members. RESULTS After 6 months, a comparison of pre- and posttrial data showed improved staff and patient satisfaction, decreased physician administrative work, and no cost-effectiveness improvement. Screening of medical conditions in the elderly improved, but no change was noted with chronic disease metrics. CONCLUSIONS Data showed improved staff and patient satisfaction, decreased physician clerical burden, increased appointment slots, mixed clinical outcomes, and did not demonstrate cost-effectiveness. The authors recommend that similar models be conducted in large settings to see if these results are reproducible.

TL;DR: The launching of the International Cost Standard set program, aiming to introduce standardized frameworks to measure costs for specific clinical conditions worldwide, is reported, reporting the launching of a scientific committee including 16 international healthcare cost assessment experts from several countries.
Abstract: This communication piece is reporting the launching of the International Cost Standard set program, aiming to introduce standardized frameworks to measure costs for specific clinical conditions worldwide. A scientific committee including 16 international healthcare cost assessment experts from several countries, and International Consortium for Health Outcomes Measurement was formed to introduce the program. The committee got together in Lisbon for a first scientific meeting, followed by an international conference where time-driven activity-based costing applied studies were shared with the community. The cost standard set program start to offer instruments for people to measure with real-world data, the financial impact of having access to health technologies, improving the ability to evaluate inequity. Those advances might represent a paradigm shift in our ability to generate cost information on an individual level.

TL;DR: In this paper , the authors evaluated changes in health care spending and utilization associated with a telehealth-based care coach-supported and behavioral health (BH) provider referral intervention in the United States.
Abstract: OBJECTIVES To evaluate changes in health care spending and utilization associated with a telehealth-based care coach-supported and behavioral health (BH) provider referral intervention in the United States. STUDY DESIGN Observational retrospective cohort study with propensity score matching of treated and control groups. METHODS Difference-in-differences (DID) analysis was used to calculate per-member per-month (PMPM) savings and changes in utilization in a treated group relative to matched controls over 36 months. The study included 1800 adults with substance use disorder (SUD), anxiety, or depression who were eligible for the intervention. Treated members (n = 900) graduated from the program. Matched control members (n = 900) were eligible but never enrolled. Primary outcomes included all-cause and disease-attributable health care cost and utilization PMPM, categorized by place of service. RESULTS There were statistically significant reductions in total all-cause medical costs of $485 PMPM (P < .001) and a 66% pre-post reduction in inpatient encounters, with $488 PMPM DID savings for inpatient admissions (P < .001) among the treated cohort compared with the control cohort over 36 months. Conversely, there were statistically significant cost increases ($110 PMPM; P < .001) for all-cause office visits in the treated cohort compared with the control cohort. Similar results were seen in SUD-attributable and BH-attributable costs. CONCLUSIONS Although the results could be affected by unmeasured confounding, they suggest that care coaching interventions that offer BH provider referrals may produce long-term savings, reductions in avoidable utilization, and increases in targeted services to treat BH conditions. Rigorous evaluations are needed to confirm these findings.
