1. Sexual trauma during military service linked to higher risk of suicide and overdose death later in life

Abstract: https://www.acpjournals.org/doi/10.7326/ANNALS-24-01145

URL goes live when the embargo lifts             

A longitudinal cohort study of older veterans found that a history of military sexual trauma (MST) is associated with increased risk for any suicide attempt and death by drug overdose in both women and men, especially those who also have post-traumatic stress disorder (PTSD). According to the authors, these findings are a call to action for policies and practices that reduce sexual trauma in the military. The study is published in Annals of Internal Medicine

 

In the first study of its kind, researchers from the University of California, San Francisco studied a national longitudinal cohort of 5,059,526 veterans aged 50 or older to determine the association between MST and risk for suicide, overdose, and related mortality later in life. The researchers stratified the study cohort by gender and MST exposure and examined whether PTSD modified the effect of MST on suicide and drug overdose death risk. The researchers found that MST was associated with an increased risk for any suicide attempt and death by suicide in both genders. The risk of suicide attempt was three times higher among men and women who had experienced MST compared to those who did not experience MST. The cumulative incidence of any late-life suicide attempts by women and men with MST were six and twelve percentage points higher than those who did not experience MST. Although MST similarly increased the risk of suicide and overdose death for both genders, MST was more than 10 times more common among women than men. MST was associated with over 60% increased risk of death by drug overdose in both genders. The findings also showed that for both men and women veterans with PTSD, MST was associated with a higher risk for suicide attempt and nonfatal attempt compared to those who only had PTSD.

A safety analysis of mRNA vaccination in a phase 1, randomized, open-label clinical trial evaluated the safety and tolerability of three investigational HIV-1 trimer mRNA vaccines. The study vaccines were found to be generally safe and tolerable. However, the researchers observed unexpected, delayed onset urticaria, or hives, in 7% of participants, highlighting the importance of promoting awareness and reporting of chronic urticaria after mRNA vaccination, adopting risk mitigation strategies in future mRNA vaccine trials, and encouraging further evaluation to determine the cause of these reactions. Urticarial reactions, mostly transient, have been reported with both licensed mRNA COVID-19 vaccines. The study is published in Annals of Internal Medicine.

 

A team of researchers funded by the National Institutes of Health analyzed the safety and tolerability of three investigational HIV-1 trimer mRNA vaccines: BG505 MD39.3 gp140 (soluble trimer gp140); BG505 MD39.3 gp151 (membrane-bound trimer gp151); and BG505 MD39.3 gp151 CD4 knockout (membrane-bound gp151 CD4KO). 108 participants without HIV aged 18 to 55 years were enrolled at 10 US clinical research sites between February and August 2022 and were randomly assigned to receive one of the three vaccines. Vaccines were administered intramuscularly at weeks 0, 8, and 24. Participants were observed for at least 30 minutes after vaccination and completed a daily symptom diary for a week after. Participants reported frequent but mild to moderate side effects including pain at the injection site, fatigue and muscle aches that were like those seen previously with licensed mRNA COVID-19 vaccines.  80 participants reported 180 adverse events (AEs), with 30 AEs related to the study vaccinations. These AEs included lymphadenopathy, axillary pain, and angioedema. Urticaria was observed in seven participants, four of which had unresolved, intermittent urticaria at 12 months. All seven participants with urticaria had prior receipt of mRNA COVID-19 vaccines, and urticaria occurred with each of the three study vaccines. The study details the first two cases of participants with delayed onset, generalized urticaria with dermographism related to study products. The mRNA platform is under investigation in many vaccines, including HIV-1 vaccines. While the mechanism behind urticarial reactions with these investigational HIV-1 mRNA vaccines is currently unknown, the researchers note that mRNA technology continues to hold great promise for vaccines and therapeutics.

3. Prior antibiotic exposure linked to increased hospital-onset antimicrobial resistant infections during pandemic

Abstract: https://www.acpjournals.org/doi/10.7326/ANNALS-24-03078

URL goes live when the embargo lifts           

A retrospective cohort study found that antimicrobial resistant (AMR) infections increased in hospitals during the pandemic due to non-hospital factors, including increased illness severity and antibiotic exposure in the 3 months prior to hospitalization. The findings are consistent with a recent Centers for Disease Control and Prevention fact sheet on AMR. The researchers say their study could inform ongoing control interventions and improve responses to future crises. The study is published in Annals of Internal Medicine.

 

Researchers from the National Institutes of Health Clinical Center and colleagues queried PINC AI to sort data from 243 U.S. hospitals between January 2018 and December 2022 to determine incidence of AMR infection and contributing factors among adult patients. They analyzed infections during three time periods: prepandemic (January 2018 to December 2019), peak pandemic (March 2020 to February 2022), and waning pandemic (March to December 2022). Encounters were screened for cultures from any source with growth of Staphylococcus aureusEnterococcus species, Acinetobacter species, Pseudomonas aeruginosa, or Enterobacterales. The AMR phenotypes analyzed included: methicillin-resistant S aureus (MRSA), vancomycin resistant Enterococci (VRE), extended-spectrum cephalosporin-resistant (carbapenem-susceptible) Enterobacterales (ECR-E), carbapenem-resistant Enterobacterales (CRE), carbapenem-resistant P aeruginosa (CR-PA), and carbapenem-resistant Acinetobacter (CRAB).  The researchers also conducted a competing risks analysis to investigate the effects of patient- and hospital-level characteristics on the risk of hospital-onset AMR infection.

 

The researchers found that of the 9,955,696 hospitalizations, there were 178,579 infection episodes associated with 1 of the 6 AMR phenotypes, equivalent to an overall incidence of 179.4 per 10,000 hospitalizations. MRSA infections were the most common overall, but CRAB infections increased the most during the pandemic. MRSA infections decreased during the pandemic and continued declining throughout 2022. VRE, CR-PA, CRE, and CRAB represented relatively greater proportions of hospital-onset infections. Overall AMR infections increased by 6.5% during the pandemic and returned to baseline levels after March 2022. Hospital-based infections had larger increases than community-based infections during the pandemic, and as the pandemic waned, community-onset AMR returned to baseline levels whereas hospital-onset AMR remained 11.6% above the baseline. Patient factors were most associated with higher hospital-onset AMR infections during the pandemic including acute illness severity. Additionally, antibiotic exposure in the prior 3 months was incrementally associated with an increased risk for hospital-onset AMR infections.

4. ACP recommends ways physicians can be more effectives advocates for patients and profession

Abstract: https://www.acpjournals.org/doi/10.7326/ANNALS-24-03973

URL goes live when the embargo lifts            

In a new policy paper published in Annals of Internal MedicineEmpowering Physicians Through Collective Action: A Position Paper from the American College of Physicians, ACP is offering recommendations about how physicians can become effective advocates for their patients and their profession through collective action.

 

ACP’s new policy paper details what the goals of collective action should be and how physicians and health systems should approach action. The recommendations start by stating that the primary objective of collective empowerment actions by physicians should be to ensure that patients have access to safe, affordable, high-quality care. The paper goes on to say that practicing physicians must be included in executive positions and on the boards of hospitals and health systems, and that they must have means to collaborate with hospital and health systems leaders.

 

ACP supports the rights of physicians to engage in protected concerted activity to amplify concerns about health and safety, working conditions, and other issues without retaliation or penalties from their employer. ACP also supports the right of physicians to engage in responsible collective bargaining, including joining a union or bargaining unit. Actions like a refusal to perform administrative requirements, billing duties, or concerted refusals to work should only be considered once all other negotiating tactics have been exhausted, and efforts have been made by all involved parties to ensure safe patient care. Finally, ACP reaffirms that independently practicing physicians should have the right to negotiate jointly with health insurance plans over terms that affect the quality of, and access to, patient care, including payment and administrative policies that adversely affect access and quality.

5. Medicaid ‘unwinding’ left many younger adults uninsured

Abstract: https://www.acpjournals.org/doi/10.7326/ANNALS-24-03261

URL goes live when the embargo lifts             

A brief research report examined the changes in uninsured rates among working-age adults 1 year after the pandemic-era Medicaid continuous enrollment provision ended. The study found that this “unwinding” led to an increase in the uninsured rate, mostly affecting younger adults, those with lower educational attainment, and combined-race groups. According to the authors, the findings highlight the critical need to mitigate further insurance loss among working-age adults, especially as policymakers consider whether to extend or terminate additional pandemic-era protections. The findings are published in Annals of Internal Medicine.  

 

Researchers from Beth Israel Deaconess Medical Center analyzed data from The Current Population Survey Annual Social and Economic Supplement (ASEC), a nationally representative survey conducted each March. The researchers used the March 2023 (before unwinding) and March 2024 (after unwinding) ASEC which included 164,778 participants aged 19 to 64 years who self-reported their insurance status and type (uninsured, Medicaid, Medicare, employer-sponsored, Marketplace or non-Marketplace). The researchers found that the uninsured rate increased from 11.1% to 11.5% from March 2023 to March 2024. This decline was driven by declines in employer-sponsored and Medicaid coverage, despite an increase in Marketplace coverage. Medicaid unwinding was associated with an increase in uninsured rates among adults aged 19 to 44 years, White and combined race adults and adults with a high school education or less. Surprisingly, there was also an association between Medicaid unwinding and an increase in uninsurance rates for those above the poverty line, but not for those below the poverty line.

6. Report details pandemic-related trends in chronic liver disease mortality  

Abstract: https://www.acpjournals.org/doi/10.7326/ANNALS-24-03218

URL goes live when the embargo lifts            

A brief research report analyzed trends in mortality for chronic liver disease (CLD) in the United States before, during and after the COVID-19 pandemic. The findings revealed disparate trends among alcohol-related liver disease (ALD), metabolic dysfunction-associated steatotic liver disease (MASLD)and hepatitis C virus (HCV)-related mortality, emphasizing the importance of establishing clinical pathways that provide uninterrupted care to persons with CLD in future public health crises. The findings are published in Annals of Internal Medicine.

 

Researchers from Stanford University and colleagues used the national mortality data set released by the National Vital Statistics System to analyze CLD deaths in persons aged 25 years and older and describe trends in mortality between 2015 and 2023. The researchers found that ALD-related mortality increased before the pandemic, sharply increased during the early pandemic and declined after the pandemic. Similar patterns were observed for MASLD-related mortality, however, the increasing trend in MASLD-related mortality was steeper than that of ALD-related mortality. HCV-related mortality steadily declined before the pandemic, remained stable during the early pandemic and decreased in the late pandemic. The findings suggest that after the early pandemic, improved health care access, universal vaccination rates and reduced social isolation likely mitigated the surge in ALD-related mortality and contributed to the decline in HCV-related mortality.

Parents with alcohol-related diagnoses are twice as likely to maltreat children




Society for the Study of Addiction





A new systematic review has found that parents and other child caregivers who have alcohol-related diagnoses are twice as likely to maltreat children in their care than parents and caregivers with no alcohol-related diagnoses.  ‘Alcohol-related diagnoses’ included alcohol-related hospitalisation, alcohol-related service use, or a history of clinically determined alcohol dependence. ‘Child maltreatment’ included physical, psychological, emotional and sexual abuse; neglect; and other types of maltreatment such as harsh parenting.

The study pooled the results from twelve studies of child maltreatment.  All were cohort studies in high-income countries: three in Australia, one in Denmark, one in New Zealand, two in South Korea, one in the United Kingdom, and four in the United States.  The sample size ranged from 501 to 84,245 (median 4782). Caregiver alcohol-related diagnoses were associated with higher child maltreatment incidence (odds ratio, 2.32; 95% confidence interval, 1.10-4.89) and recurrence (1.92; 1.13-3.28) compared with caregivers without alcohol-related diagnoses.

Lead author Dr June Leung, of the SHORE & Whariki Research Centre, Massey University, says “To our knowledge, this is the first systematic review of the relationship between caregiver alcohol use and all types of child maltreatment.  We found consistent associations between caregiver alcohol-related diagnoses and child maltreatment. We also could not rule out a link between any caregiver drinking and child maltreatment. Our findings call for stronger actions to limit alcohol harm, including child maltreatment.”

Policymakers often overlook the challenges faced by shrinking small and medium-sized cities. Yet, keeping these cities sustainable is crucial for many urban stakeholders. Unfortunately, the methods that have succeeded in large cities cannot be unilaterally applied to combat this issue. This suggests that a research gap on effective urban management in small and medium-sized cities exists.

Dr. Haruka Kato, a junior associate professor at Osaka Metropolitan University, examined the types of municipal expenditures that correlated with population changes in small and medium-sized cities. The research design used cross-sectional studies from 2007 to 2022 of all small and medium-sized cities in Japan. The nonlinear relationship between data was analyzed using the eXtreme Gradient Boosting algorithm.

The results revealed that 1288 cities were shrinking, accounting for 82.56% of all small and medium-sized cities in Japan. Further, this study identified the types of per capita municipal expenditures that correlated with population change, which were often associated with welfare expenditures. Specifically, the population grew in cities that increased per capita expenditures on children and decreased those on welfare recipients and the older population. Additionally, city planning expenditures were also effective, but only in the maintenance and construction of streets.

“In recent years, urban policymakers have adopted an urban management perspective. With limited financial resources, policymakers must decide what and how much to invest in citizens,” said Dr. Kato. “Our research clearly suggests prioritizing child welfare expenditures as a key strategy to sustain populations in small and medium-sized cities.”

The findings were published in the Journal of Urban Management.

The sensation of controlling one’s body and things in the environment is known as sense of agency (SoA). Not only is SoA pivotal for tasks and well-being in everyday life, but its mechanisms have become increasingly important for the development of human-computer interfaces in new technology. This need has fueled research in this area, in particular to understand how SoA is generated from scratch in unfamiliar environments. Researchers at the University of Tokyo performed experiments involving hand-to-screen mapping using a specialized glove and highlighted the role of motor exploration in generating experience of self-agency. Their findings could contribute to future health and technology applications.

Traditionally, SoA has been explained by a framework called the comparator model. “According to this model, the brain maps the predicted outcomes of actions, referred to as an internal model. SoA arises when those predictions match with actual sensory feedback,” said Takumi Tanaka, assistant professor at the University of Tokyo’s Graduate School of Humanities and Sociology and co-author of the current study.

An issue arises when considering acquisition of new motor skills, such as learning a sport or relearning everyday activities after a neurological injury. While the comparator model assumes that outcomes from actions are partly predictable, new learners instead often attempt actions first and explore what happens as a result. “This process is called motor exploration, which helps form the internal model and generalize the learned outcomes,” said Tanaka.

The team set out to understand how SoA develops in new motor learning scenarios. To address this, it was necessary to track changes in SoA from the pre-learning stage where predictions are yet to be formed.

The motor learning task chosen for the study involved a data glove to control a cursor on the screen through finger movements. The investigation was divided into two experiments. The first required participants to learn the hand-to-screen spatial mapping from scratch through trial and error. At each learning phase, the researchers measured how strongly participants felt that they were in control of the cursor, including when the cursor movement was subtly distorted in space or time. The results showed that during the pre-learning stage, participants primarily relied on temporal synchronicity of hand and cursor movements to judge whether they were in control. “After sufficient practice, however, participants would feel that the cursor movement aligned with their own when it adhered to the learned mapping — a trend that was more pronounced in those who achieved higher proficiency,” said Tanaka.

No similar enhancement in SoA was observed in the second experiment, which was designed to suppress motor exploration by having participants simply imitate presented gestures to transport the cursor to a target position. “This,” according to Tanaka, “indicates that merely memorizing gesture-to-cursor associations is not enough; to build a strong sense of agency, learners must actively discover the underlying rules, for instance, that bending the index finger moves the cursor to the right. We call this a structural representation, and it seems to develop through motor exploration.”

This study provides key insights into the evolution of SoA during the acquisition of new motor skills. It enriches existing SoA frameworks by elucidating the origin of the comparator process, and could help refine applications in rehabilitation, virtual reality and brain-machine interfaces in the future.

Prevention instead of reaction: Intelligent, networked systems for structural monitoring



A research team at Graz University of Technology has developed a system for structural monitoring that can be integrated directly into structural management and used sustainably for preventive maintenance planning.

The safety and durability of transport and building infrastructure are in the interests of both operators and users. To maintain the best possible building condition at the lowest possible cost, effective monitoring is required to improve condition assessment. Although there are suitable monitoring systems, they are usually not properly networked, not directly integrated into the building management system and their data is often not usable in the long term due to incomplete documentation and non-standardised evaluation procedures. In the PreMainSHM project, a team at Graz University of Technology (TU Graz) led by Markus Krüger from the Institute of Technology and Testing of Construction Materials (IMBT) and Werner Lienhart from the Institute of Engineering Geodesy and Measurement Systems (IGMS) has tackled this issue and developed a preventive structural monitoring system with intelligent, networked systems that can be integrated directly into standard structural management software.

Data must be usable

“The technologies we have for infrastructure monitoring provide a lot of data that complement each other well,” says Werner Lienhart. “But simply collecting data aimlessly is not helpful for forecasting the development of the building’s condition and its service life, including proactive maintenance planning. Our aim was therefore to develop a holistic solution that would make it possible to gain directly usable findings from structural monitoring for service life forecasts and maintenance planning in a long-term and cost-efficient manner. This allows building operators to act proactively rather than reactively.”

The centrepiece of the project was the intelligent linking of various monitoring technologies. A crucial role is played by the high-precision fibre-optic monitoring developed at the Institute of Engineering Geodesy and Measurement Systems, which provides detailed insights into material behaviour, as well as cost-effective and flexible wireless sensor networks, which have been further developed at the IMBT. By combining these technologies, comprehensive data on the condition of and stress loads on structures can be recorded. The researchers paid particular attention to the application of the FAIR data principles (Findability, Accessibility, Interoperability, Reusability) in order to ensure the long-term usability and exchange of the data obtained.

Linking with BIM and GIS

To close the gap between data acquisition and building management, the project partners developed a simple but flexible, entity-based data model. This model enables a hierarchical structuring of the buildings and links the measurement data with the corresponding components and sensors. This facilitates access to relevant information and enables interoperability with other software systems such as BIM (Building Information Modelling) and GIS (Geographic Information Systems). A digital twin was also implemented to visualise and manage the building data.

It was also important to ensure that the sensor data collected was reliable. Although sensors are currently calibrated in advance, this is done under controlled conditions that are rarely found in a building. Instead, the temperatures and humidity change and there are other influences such as vibrations. To this end, the project team developed appropriate methods that take into account the influence of the environment on the sensor data.

Practical testing on Laxenburg Bridge

The practical testing and validation of the developed concepts took place at Laxenburg Bridge in Vienna. Various sensor technologies were used there, including wireless sensors for monitoring inclinations and crack widths as well as fibre-optic systems for high-resolution strain measurement and crack detection under traffic load.

“PreMainSHM has demonstrated the potential of intelligent and networked structural monitoring for the safe and sustainable maintenance of buildings and infrastructure,” says Markus Krüger. “This potential must now be utilised to make the management of bridges and other engineering structures fit for the future. That’s why we have also created a guidance document in the project, which should help to ensure that future monitoring projects not only provide data, but also usable information for well-founded decisions in building management.”
