Wastewater Target Pathogens of Public Health Importance for Expanded Sampling, Houston, Texas, USA.

Building on the success of initiatives put forth during the COVID-19 pandemic response, US health officials are expanding wastewater surveillance programs to track other target pathogens and diseases of public health interest. The Houston Health Department in Houston, Texas, USA, conducted a hypothesis-generating study whereby infectious disease subject matter experts suggested potential targets. This study addressed 2 criteria recommended by the National Academies of Sciences, Engineering, and Medicine for selecting wastewater targets. Results can be used as a basis of a questionnaire for a future population-based study to recommend targets of highest priority to include for expanded wastewater sampling.

Inadequate insurance coverage for overweight/obesity management.

To discuss the social, psychological, and access barriers that inhibit weight loss, and to propose steps and initiatives for addressing the growing obesity epidemic. Narrative review of the obesity epidemic in the US and associated racial/ethnic and socioeconomicdisparities. An internet search of relevant studies and government reports was conducted. Obesity is a significant health crisis affecting more than 123 million adults and children/adolescents in the US. An estimated 1 in 5 deaths in Black and White individuals aged 40 to 85 years in the US is attributable to obesity. Obesity puts individuals at elevated risk for type 2 diabetes, cardiovascular disease, chronic kidney disease, gastrointestinal disorders, nonalcoholic fatty liver disease, cancer, respiratory ailments, dementia/Alzheimer disease, and other disorders. In the US, significantly more Black (49.9%) and Hispanic (45.6%) individuals are affected by obesity than White (41.4%) and Asian (16.1%) individuals. Health care costs for obesity account for more than $260billion of annual US health care spending-more than 50% greater in excess annual medical costs per person than individuals with normal weight. Addressing the obesity epidemic will require a multifaceted approach that focuses on prevention, treatment, and reducing the impact of stigma. Continued advocacy and education efforts are necessary to make progress and improve the health and well-being of individuals affected by obesity.

The Neurologist's Guide to Drug Pricing in the United States.

As newer, innovative neurology drugs enter the US health care system, neurologists should consider the cost of these treatments in addition to their efficacy, safety, and tolerability. To do so thoughtfully requires an understanding of how prescription drugs are priced in the United States. The process of drug pricing is linked to the distribution supply chain and the many stakeholders involved. Stakeholders include pharmaceutical manufacturers; wholesalers; pharmacies; pharmacy benefit managers; payers, including health insurers; hospital systems; neurologists and other clinicians; and patients. Drug pricing has taken center stage as the Inflation Reduction Act of 2022 has set maximum out-of-pocket expenses for Medicare beneficiaries for the first time in the program's history and limits drug price increases for a select group of Medicare Part D drugs. This article describes the US drug distribution supply chain and its stakeholders and introduces key drug pricing terms; a brief description of how rebates are generally estimated will also be discussed. Finally, as newer neurology outpatient drugs enter the market, the "value" of drugs will be described through cost-effectiveness terminology and their utility for the clinical neurologist.

The psychological burden associated with metabolic syndrome: Evidence from UK and US older adults.

We examined the psychological burden associated with metabolic syndrome (MetSyn). We used comparable longitudinal data of older adults (≥50years) from the UK (English Longitudinal Study of Aging) and the US (Health and Retirement Study). We defined MetSyn based on biomarker assessments (e.g., blood pressure, impaired glycemic control). Using regression models, we tested a range of individual psychological outcomes (e.g., depressive symptoms) associated with MetSyn. We also examined whether these psychological outcomes may explain or moderate the link between MetSyn and non-communicable diseases (NCDs). MetSyn was associated cross-sectionally with a range of psychological outcomes, including depression, anxiety, loneliness, hopelessness, cynical hostility, social strain, negative affect and decreased positive affect, social support and purpose in life. There was no convincing evidence that psychological factors interacted with or explained (mediated) the relationship between MetSyn and increased risk of developing NCD over 10-year follow-ups. MetSyn and the psychological burden outcomes examined may have independent effects on NCD risk.

Space Alpha Particle Fluxes Towards the Earth Increase Human Mortality. Is It Possible an Intervention of Non-Human Intelligence?

In the present work, a dangerous phenomenon for mankind is described, increasing mortality, mainly from the most deadly diseases on the planet – circulatory diseases, in particular ischemic heart diseases. In the joint analysis of data from satellites in orbit around the Earth and from the health statistics sources EUROSTAT and US medical statistics, it became clear that, by some mechanism, flows of positively charged particles with high energy entering the Earth's orbit increase human mortality, mainly from diseases of the circulatory system, but also from diseases of many other organs and systems of the human body. The circulatory disease mortality increase as a result of said alpha radiation is by an average of 5% to 15% in a zone of maximum risk in the Northern Hemisphere, parallel to the equator and bounded by the parallels of 30° and 50° north latitude. A hypothetical mechanism based on observational evidence has been proposed, according to which this dangerous phenomenon is due to solar alpha particles of high energy sufficient to overcome the resistance of the atmosphere and reach the Earth's surface in a limited area of maximum death impact. The impact is most often short-lasting – for minutes, hours, or sometimes a few days. In the area with maximum risk, alpha particles have a detrimental effect on the human body. The area with maximum risk is limited in area and in time by two conditions 1. the path of the particles through the atmosphere to the Earth's surface is as short as possible (during the local culmination of the Sun, local noon) and 2. the direction of the incoming alpha particles coincides with the direction of the vector of geomagnetic induction at the point of maximum risk, where alpha particles are not affected by the deflecting force of the geomagnetic field. Such a coincidence between the culmination of the Sun, which changes during the year, and the direction of the geomagnetic induction vector, which is unchanged for a given point of observation, occurs twice a year for points with a geographical latitude of 30° – 50° N. Examples are given confirming the proposed mechanism of action. In the second part of the study, attention is paid to the nature of alpha particle streams reaching the Earth's orbit. In addition to those emitted by the Sun as a result of natural processes, there are also series of pulses lasting less than 5 minutes, with strict periodicity in the series day or week, with the same moment of registration of the pulses and coincidence of the pulses in the series by magnitude over extended time intervals, sometimes over the lifetime of the series from months to years. The alpha particles from each pulse in the series bombard the Earth's surface always in the same place. There are many such series, differing in time of recording and period, each of which is focused on a certain region of the Earth's surface. Such are, in particular, the series of pulses affecting the territory of the USA, Europe, and Central Asia. There is statistical confirmation in the US health statistics that the series of pulses affecting the country cause an increase in the mortality of ischemic heart disease by up to 5%. The lack of free access to detailed statistics on the cases of death in the other countries affected by the phenomenon does not allow a conclusion of the impact of the series of pulses of alpha particles on the health of their inhabitants. The strange characteristics of the mentioned series of pulses of alpha particles do not exclude the hypothesis that they are artificially generated from a non-human mind. The level of technological development of human civilization does not imply the possibility for it to generate such large-scale processes as the series of pulses of alpha particles, i.e. the highly developed non-human mind that generates them has nothing to do with human civilization. The series of pulses may be navigational signals causing unwitting casualties to humanity, but they may also be a form of murderous contact with a higher civilization that we have long sought, expecting only benefits after its realization, not suspecting that we live in this nightmarish contact indefinitely.

Association of chronic opioid therapy and opioid use disorder with COVID-19-related hospitalization and mortality: Evidence from three health systems in the United States

ObjectiveChronic opioid use can lead to detrimental effects on the immune and various organ systems that put individuals prescribed chronic opioid therapy (COT) for pain and those with an opioid use disorder (OUD) at risk for severe COVID-19 disease. We assessed the association of COT and OUD with COVID-19-related hospitalization and death to inform targeted interventions to improve clinical outcomes in COVID-19 patients who use opioids. MethodsWe conducted a retrospective cohort study of adults ages ≥ 18 with laboratory-confirmed SARS-CoV-2 infection in 2020 and 2021 from three US health systems. We used Cox proportional hazards regression to estimate the 30-day risk of COVID-19-related hospitalization and death associated with two opioid exposures (COT and OUD) following an infection. ResultsThe study cohort included 53,123 patients with SARS-CoV-2 infection and a mean (SD) age of 45.1 (16.5), of whom 1,059 (2.0 %) were exposed to COT and 269 (0.5 %) had an OUD diagnosis in the year prior to infection. There were 2,270 observed COVID-19-related hospitalizations or deaths (1.6 per 1,000 person-days, 95 % CI 1.5–1.7). In the fully adjusted model, COT was not associated with increased risk (HR 1.19; 95 % CI, 0.98–1.43), while past-year OUD was independently associated with severe COVID-19 disease (HR 1.82; 95 % CI, 1.18–2.80). Past-year OUD remained associated with increased risk in post-hoc analysis with COVID-19-related hospitalization alone as the outcome (HR 2.00; 95 % CI, 1.30–3.08). ConclusionsPast-year OUD is a potential independent risk factor for severe COVID-19 disease that warrants monitoring to improve the prognosis of patients with COVID-19.

Associations of social engagement, and loneliness with the progression and reversal of frailty: longitudinal investigations of two prospective cohorts from the UK and the USA.

Social connections may impact the dynamic trajectory of frailty. Using data from the British Regional Heart Study (BRHS) in the UK (n = 715), and the US Health, Aging and Body Composition (Health ABC) Study (n = 1256), we conducted multinominal regression analyses to examine the association of baseline and change in social engagement and loneliness with progression to pre-frailty and frailty, as well as their association with reversal to pre-frailty and robust status among older adults. A higher level of social engagement at baseline (BRHS: relative risk ratio (RRR) 0.69 [95%CI 0.55-0.85]; Health ABC: 0.56 [0.45-0.70]), as well as increase in social engagement (BRHS: 0.73, [0.59-0.90]; Health ABC: 0.51 [0.41-0.63]), were associated with a lower risk of developing frailty. In BRHS, a higher level of loneliness at baseline (1.42 [1.10-1.83]) and an increase in loneliness (1.50 [1.18-1.90]), increased the risk of developing frailty. For reversal of frailty, higher social engagement at baseline (Health ABC: 1.63 [1.08-2.47]) and an increase in social engagement (BRHS:1.74[1.18-2.50]; Health ABC: 1.79[1.17-.274]) were beneficial. Social connections maybe potentially important and modifiable factors in both preventing and reversing progression of frailty in older adults.

Telehealth Uptake Among Hispanic People During COVID-19: Retrospective Observational Study.

The Hispanic community represents a sizeable community that experiences inequities in the US health care system. As the system has moved toward digital health platforms, evaluating the potential impact on Hispanic communities is critical. The study aimed to investigate demographic, socioeconomic, and behavioral factors contributing to low telehealth use in Hispanic communities. We used a retrospective observation study design to examine the study objectives. The COVID-19 Research Database Consortium provided the Analytics IQ PeopleCore consumer data and Office Alley claims data. The study period was from March 2020 to April 2021. Multiple logistic regression was used to determine the odds of using telehealth services. We examined 3,478,287 unique Hispanic patients, 16.6% (577,396) of whom used telehealth. Results suggested that patients aged between 18 and 44 years were more likely to use telehealth (odds ratio [OR] 1.07, 95% CI 1.05-1.1; P<.001) than patients aged older than 65 years. Across all age groups, patients with high incomes were at least 20% more likely to use telehealth than patients with lower incomes (P<.001); patients who had a primary care physician (P=.01), exhibited high medical usage (P<.001), or were interested in exercise (P=.03) were more likely to use telehealth; patients who had unhealthy behaviors such as smoking and alcohol consumption were less likely to use telehealth (P<.001). Male patients were less likely than female patients to use telehealth among patients aged 65 years and older (OR 0.94, 95% CI 0.93-0.95; P<.001), while male patients aged between 18 and 44 years were more likely to use telehealth (OR 1.05, 95% CI 1.03-1.07; P<.001). Among patients younger than 65 years, full-time employment was positively associated with telehealth use (P<.001). Patients aged between 18 and 44 years with high school or less education were 2% less likely to use telehealth (OR 0.98, 95% CI 0.97-0.99; P=.005). Results also revealed a positive association with using WebMD (WebMD LLC) among patients aged older than 44 years (P<.001), while there was a negative association with electronic prescriptions among those who were aged between 18 and 44 years (P=.009) and aged between 45 and 64 years (P=.004). This study demonstrates that telehealth use among Hispanic communities is dependent upon factors such as age, gender, education, socioeconomic status, current health care engagement, and health behaviors. To address these challenges, we advocate for interdisciplinary approaches that involve medical professionals, insurance providers, and community-based services actively engaging with Hispanic communities and promoting telehealth use. We propose the following recommendations: enhance access to health insurance, improve access to primary care providers, and allocate fiscal and educational resources to support telehealth use. As telehealth increasingly shapes health care delivery, it is vital for professionals to facilitate the use of all available avenues for accessing care.

Consilience of healthcare legislation, complexity science & computational analysis

Our US Health Care System (HCS) has evolved from simple to complex and needs reform. Thus far, all legislative initiatives have failed to result in establishing a friendly, cost-effective, quality healthcare system. The question becomes, can Complexity Science (CS) and computational analytic platform modeling be used to help create better Health Care Policies (HCP) and reform our all too complex HCS? Modeling has been used in many diverse disciplines but has yet to be utilized in preemptive evaluation of major US legislative HCPs. Review of US Health Care Policy History (HCPH) viewed in the context of a Complex Adaptive System(CAS) reveals how, unanticipated historical events, politics, social, and personal leadership have tangentially shaped our US HCPs. Future construction of HCPs with the help of CS, and preemptive computational modeling (CM) techniques, will hopefully yield stronger conclusions in legislative HCP construction and advance our US HCS into one with dynamic resilience.

Factors Influencing Neuromuscular Blockade Reversal Choice in the United States Before and During the COVID-19 Pandemic: Retrospective Longitudinal Analysis.

Neuromuscular blockade (NMB) agents are a critical component of balanced anesthesia. NMB reversal methods can include spontaneous reversal, sugammadex, or neostigmine and the choice of reversal strategy can depend on various factors. Unanticipated changes to clinical practice emerged due to the COVID-19 pandemic, and a better understanding of how NMB reversal trends were affected by the pandemic may help provide insight into how providers view the tradeoffs in the choice of NMB reversal agents. We aim to analyze NMB reversal agent use patterns for US adult inpatient surgeries before and after the COVID-19 outbreak to determine whether pandemic-related practice changes affected use trends. A retrospective longitudinal analysis of a large all-payer national electronic US health care database (PINC AI Healthcare Database) was conducted to identify the use patterns of NMB reversal during early, middle, and late COVID-19 (EC, MC, and LC, respectively) time periods. Factors associated with NMB reversal choices in inpatient surgeries were assessed before and after the COVID-19 pandemic reached the United States. Multivariate logistic regression assessed the impact of the pandemic on NMB reversal, accounting for patient, clinical, procedural, and site characteristics. A counterfactual framework was used to understand if patient characteristics affected how COVID-19-era patients would have been treated before the pandemic. More than 3.2 million inpatients experiencing over 3.6 million surgical procedures across 931 sites that met all inclusion criteria were identified between March 1, 2017, and December 31, 2021. NMB reversal trends showed a steady increase in reversal with sugammadex over time, with the trend from January 2018 onwards being linear with time (R2>0.99). Multivariate analysis showed that the post-COVID-19 time periods had a small but statistically significant effect on the trend, as measured by the interaction terms of the COVID-19 time periods and the time trend in NMB reversal. A slight increase in the likelihood of sugammadex reversal was observed during EC relative to the pre-COVID-19 trend (odds ratio [OR] 1.008, 95% CI 1.003-1.014; P=.003), followed by negation of that increase during MC (OR 0.992, 95% CI 0.987-0.997; P<.001), and no significant interaction identified during LC (OR 1.001, 95% CI 0.996-1.005; P=.81). Conversely, active reversal (using either sugammadex or neostigmine) did not show a significant association relative to spontaneous reversal, or a change in trend, during EC or MC (P>.05), though a slight decrease in the active reversal trend was observed during LC (OR 0.987, 95% CI 0.983-0.992; P<.001). We observed a steady increase in NMB active reversal overall, and specifically with sugammadex compared to neostigmine, during periods before and after the COVID-19 outbreak. Small, transitory alterations in the NMB reversal trends were observed during the height of the COVID-19 pandemic, though these alterations were independent of the underlying NMB reversal time trends.

Stakeholder perspectives on the sustainability of the United States biosimilars market.

Biologic therapies play a critical role in modern medical practice but also present challenges for payers, patients, and other stakeholders because of their high cost. Biosimilars can mitigate the cost pressures of reference biologic therapy because they are typically priced at least 25% lower, providing a means to administer cutting-edge biologic therapy while also managing cost of care. In fact, the US health care system has saved an estimated $23.6 billion from use of biosimilars. However, the market is still in a nascent phase of development, and early cost-saving successes are not guaranteed to persist unless sustainable market conditions are established. To better understand the perspectives of stakeholders about opportunities and threats to the sustainability of the US biosimilar market, a multistakeholder roundtable discussion was convened in December of 2023 and included health care payers, providers, self-insured employers, a manufacturer, and a biosimilar research and advocacy organization. The objective of this commentary, authored by the roundtable participants, is to posit specific opportunities and threats that stakeholders should consider to better facilitate sustainable biosimilar market conditions in the United States. We highlight key points, including (1) biosimilar price volatility with large quarter-on-quarter declines for most products; (2) perverse economic incentives that encourage providers to use more expensive reference products because reimbursement dynamics make them more profitable; (3) complex rebate structures that create barriers to biosimilar access; and (4) ongoing changes to the legal and regulatory environment, including evidence requirements to gain "interchangeable" status. We conclude with an overview of potential policy solutions to address the sustainability opportunities and threats. The authors welcome the opportunity to advance this dialogue toward action and encourage additional stakeholders to join the effort. We are optimistic that, through informed decision-making and compromise, we can collectively achieve a robust and sustainable US biosimilars market that appropriately benefits all stakeholders.

Medical Students' Views of the Future in a Rapidly Changing World.

Physicians have long been considered valued members of a solid US health care system. Significant changes in medical education, health care, and society at-large suggest that current medical students may face a different future. To help guide educators and policy makers, we set out to understand medical students' perceptions of the future of health care and their place in it. In year one of a longitudinal study, we conducted in-depth interviews of Case Western Reserve University medical students. A multidisciplinary team performed iterative thematic analyses and sampling until reaching saturation on major themes. Eleven medical student participants described social and health care issues as major influences on their professional futures. Concerns included health care system failings, unsustainable costs, climate change, demographic shifts, disinformation, and public distrust in health care. Students looked forward to team practice and using technology, data, and artificial intelligence in care delivery. They hoped for greater access and equity in health care, with a focus on prevention and social, behavioral, and environmental drivers of health. Most students expected to be employed rather than in private practice and sought time/flexibility for professional and personal interests. Paying off medical school debt and advocating for patients and change were priorities. Many saw primary care as important, but fewer envisioned it as their career path of choice. Medical students envision a future shaped by health care systems and social issues. These findings can inform those helping students prepare for uncertainty and rapid change in their careers, their lives, and the lives of their patients.

The mediating role of systemic inflammation and moderating role of racialization in disparities in incident dementia

BackgroundExposure to systemic racism is linked to increased dementia burden. To assess systemic inflammation as a potential pathway linking exposure to racism and dementia disparities, we investigated the mediating role of C-reactive protein (CRP), a systemic inflammation marker, and the moderating role of the racialization process in incident dementia.MethodsIn the US Health and Retirement Study (n = 6,908), serum CRP was measured at baseline (2006, 2008 waves). Incident dementia was classified by cognitive tests over a six-year follow-up. Self-reported racialized categories were a proxy for exposure to the racialization process. We decomposed racialized disparities in dementia incidence (non-Hispanic Black and/or Hispanic vs. non-Hispanic white) into 1) the mediated effect of CRP, 2) the moderated portion attributable to the interaction between racialized group membership and CRP, and 3) the controlled direct effect (other pathways through which racism operates).ResultsThe 6-year cumulative incidence of dementia is 12%. Among minoritized participants (i.e., non-Hispanic Black and/or Hispanic), high CRP levels ( ≥ 75th percentile or 4.73μg/mL) are associated with 1.26 (95%CI: 0.98, 1.62) times greater risk of incident dementia than low CRP ( < 4.73μg/mL). Decomposition analysis comparing minoritized versus non-Hispanic white participants shows that the mediating effect of CRP accounts for 3% (95% CI: 0%, 6%) of the racial disparity, while the interaction effect between minoritized group status and high CRP accounts for 14% (95% CI: 1%, 27%) of the disparity. Findings are robust to potential violations of causal mediation assumptions.ConclusionsMinoritized group membership modifies the relationship between systemic inflammation and incident dementia.

In-Person and Teleconsultation Services at a National Hospital in Peru: Time Series Analysis of General and Psychiatric Care Amid the COVID-19 Pandemic.

The COVID-19 pandemic led to a global reduction in health care accessibility for both infected and noninfected patients, posing a particular burden on those with chronic conditions, including mental health issues. Peru experienced significant devastation from the pandemic, resulting in a collapsed health care system and leading to the world's highest per capita mortality rate as a result of COVID-19. Understanding the trends in health care utilization, particularly in mental health care, is crucial for informing pandemic response efforts and guiding future recovery strategies. This study aims to analyze the trends of outpatient medical and psychiatric consultations during the COVID-19 pandemic in a national hospital in Peru. This observational study was conducted at a national hospital in Lima, Peru. We analyzed data on user care across all services, including psychiatric services, from May 2019 to December 2022. The data were calculated for users served per month, including the number of users seen monthly in mental health services. Sociodemographic variables such as sex (female or male), age (≥0 years), type of medical appointment (regular or additional), and modality of care (in-person or teleconsultations) were taken into account. An interrupted time series regression model was conducted to assess the number of outpatient medical and psychiatric consultations. Subgroup analyses were performed based on service modality, including overall consultations, telemonitoring/teleconsultations only, or face-to-face only, for all service users and for mental health service users. A total of 1,515,439 participants were included, with females comprising 275,444/484,994 (56.80%) of the samples. Only 345,605/1,515,439 (22.81%) visits involved telemedicine. The total monthly outpatient visits were significantly reduced compared with the expected projection (P<.001) at the beginning of the pandemic, followed by a later monthly increment of 298.7 users. Face-to-face interventions experienced a significant reduction at the beginning of the pandemic (P<.001), gradually recovering in the following months. By contrast, telemedicine use initially increased but subsequently declined toward the end of the pandemic. A similar trend was observed in mental health units. During the pandemic years, health care utilization in both general and psychiatric services experienced a significant decrease, particularly at the beginning of the pandemic (March 2020). However, no significant trends were observed in either case throughout the pandemic period. Telemedicine consultations witnessed a significant increase overall during this period, particularly among mental health users.

Semaglutide vs Tirzepatide for Weight Loss in Adults With Overweight or Obesity

Although tirzepatide and semaglutide were shown to reduce weight in randomized clinical trials, data from head-to-head comparisons in populations with overweight or obesity are not yet available. To compare on-treatment weight loss and rates of gastrointestinal adverse events (AEs) among adults with overweight or obesity receiving tirzepatide or semaglutide labeled for type 2 diabetes (T2D) in a clinical setting. In this cohort study, adults with overweight or obesity receiving semaglutide or tirzepatide between May 2022 and September 2023 were identified using electronic health record (EHR) data linked to dispensing information from a collective of US health care systems. On-treatment weight outcomes through November 3, 2023, were assessed. Adults with overweight or obesity and regular care in the year before initiation, no prior glucagon-like peptide 1 receptor agonist receptor agonist use, a prescription within 60 days prior to initiation, and an available baseline weight were identified. The analysis was completed on April 3, 2024. Tirzepatide or semaglutide in formulations labeled for T2D, on or off label. On-treatment weight change in a propensity score-matched population, assessed as hazard of achieving 5% or greater, 10% or greater, and 15% or greater weight loss, and percentage change in weight at 3, 6, and 12 months. Hazards of gastrointestinal AEs were compared. Among 41 222 adults meeting the study criteria (semaglutide, 32 029; tirzepatide, 9193), 18 386 remained after propensity score matching. The mean (SD) age was 52.0 (12.9) years, 12 970 were female (70.5%), 14 182 were white (77.1%), 2171 Black (11.8%), 354 Asian (1.9%), 1679 were of other or unknown race, and 9563 (52.0%) had T2D. The mean (SD) baseline weight was 110 (25.8) kg. Follow-up was ended by discontinuation for 5140 patients (55.9%) receiving tirzepatide and 4823 (52.5%) receiving semaglutide. Patients receiving tirzepatide were significantly more likely to achieve weight loss (≥5%; hazard ratio [HR], 1.76, 95% CI, 1.68, 1.84; ≥10%; HR, 2.54; 95% CI, 2.37, 2.73; and ≥15%; HR, 3.24; 95% CI, 2.91, 3.61). On-treatment changes in weight were larger for patients receiving tirzepatide at 3 months (difference, -2.4%; 95% CI -2.5% to -2.2%), 6 months (difference, -4.3%; 95% CI, -4.7% to -4.0%), and 12 months (difference, -6.9%; 95% CI, -7.9% to -5.8%). Rates of gastrointestinal AEs were similar between groups. In this population of adults with overweight or obesity, use of tirzepatide was associated with significantly greater weight loss than semaglutide. Future study is needed to understand differences in other important outcomes.

Confronting private equity in healthcare: challenges and opportunities for relocalising the US health sector

Confronting private equity in healthcare: challenges and opportunities for relocalising the US health sector

Could differential under-reporting of loneliness between men and women bias the gender-specific association between loneliness duration and rate of memory decline? A probabilistic bias analysis of effect modification.

Gender is an observed effect modifier of the association between loneliness and memory aging. However, this effect modification may be a result of information bias due to differential loneliness under-reporting by gender. We applied probabilistic bias analyses to examine whether effect modification of the loneliness-memory decline relationship by gender is retained under three simulation scenarios with various magnitudes of differential loneliness under-reporting between men and women. Data were from biennial interviews with adults aged 50+ in the US Health and Retirement Study from 1996-2016 (5,646 women and 3,386 men). Loneliness status (yes vs. no) was measured from 1996-2004 using the CES-D loneliness item and memory was measured from 2004-2016. Simulated sensitivity and specificity of the loneliness measure were informed by a validation study using the UCLA Loneliness Scale as a gold standard. The likelihood of observing effect modification by gender was higher than 90% in all simulations, although the likelihood reduced with an increasing difference in magnitude of the loneliness under-reporting between men and women. The gender difference in loneliness under-reporting did not meaningfully affect the observed effect modification by gender in our simulations. Our simulation approach may be promising to quantify potential information bias in effect modification analyses.

Iliac Accessory Rod Technique for Rod Fracture Prevention in Long Fusion Constructs: 2-Dimensional Operative Video.

Implant-related complications in surgery for adult spinal deformity (ASD) account for roughly $1 billion US health care expenditures over 5 years, with a majority due to primary rod fracture.1,2 Traditional two-rod constructs have demonstrated rod fracture rates of up to 40%, with a median time to fracture of 3 years.3 Current supplementary rod techniques for decreasing rod fractures inadequately address the issue of increased strain across the lumbosacral junction.4 Here, we describe a novel four-rod technique using "iliac accessory rods," designed to mitigate rod fractures by reinforcing osteotomy levels and dispersing biomechanical stress across the lumbosacral junction. Compared with other supplementary rod techniques for ASD, iliac accessory rods anchor to independent iliac bolts.5 The added fixation points across the lumbosacral junction (4 iliac bolts total) substantially offloads stress on primary rods, most of which fracture near the lumbosacral junction.3 Additionally, connecting these rods to primary rods rostrally via side-to-side connectors, above the osteotomy levels, ensures mobile osteotomy segments are reinforced. Presented is a 78-year-old woman with ASD and worsening lower back pain, radiculopathy, and bilateral leg weakness who failed nonoperative management. She underwent T9 to bi-iliac instrumented fusion with L1-S1 posterior column osteotomies, L4-S1 transforaminal lumbar interbody fusions, and bilateral iliac accessory rod fixation. Postoperatively, she recovered well and had improvement in her symptoms. Imaging revealed correction of spinal alignment. The patient consented to the procedure, and the participants and any identifiable individuals consented to publication of his/her image. Institutional Review Board approval was waived because of institutional exemption policy.

Clarifying terminology and definitions in education services for mental health users: A disambiguation study.

In the wake of the mental health crisis in children and adolescents, the coordination of education and mental health services has become a global priority. However, differing terminologies and classifications across sectors, hinder effective comparison. The classification in education focuses mainly on outputs like qualifications or throughputs like teaching programs. This proof-of-concept study tested the applicability of a standard classification of health services, the Description and Evaluation of Services and DirectoriEs (DESDE), to evaluate education services for mental health users in the context of Spain and The Netherlands. It was conducted alongside the PECUNIA project, that sought to develop methods for the assessment of mental health costs and outcomes in different sectors. The study followed an ontoterminology approach involving: 1) identification of services from a predefined list of 46 resource-use items, 2) disambiguation of identified services with the DESDE, and classifying them as accurate, ambiguous, vague or confuse; and 3) external validation by an expert panel. The analysis was conducted at the level of type of resource, target population and care provision. From the initial list, only ten of the resources could be categorized as services using DESDE, and not activities, interventions or professionals. Only four of them (8,65%) were accurate across all disambiguation categories. Experts were unaware of terminology problems in classification of service provision in the education sector. Classifications and glossaries can clarify service naming, description and costing allowing comparative effectiveness analysis and facilitating cross-sectoral planning. This should be grounded in common methodologies, tools, and units of analysis.
