The critical care literature in the US has recently brought attention to the impact an ICU experience can have long after the patient survives critical illness, particularly if delirium was present. Current recommendations to mitigate post-intensive care syndrome (PICS) are embedded in patient and family-centered care and aim to promote family presence in the ICU, provide support for decision-making, and enhance communication with the health-care team. Evidence-based interventions are few in number but include use of an ICU diary to minimize the psychological and emotional sequelae affecting patients and family members in the months following the ICU stay. In this paper we describe our efforts to implement an ICU diary and solicit feedback on its role in fostering teamwork and communication between patients, family members, and ICU staff. Next steps will involve a PICS follow-up clinic where trained staff will coordinate specialty referrals and perform long-term monitoring of mental health and other quality of life outcomes.

In the United States, national ecological studies suggest a positive impact of COVID-19 vaccination coverage on outcomes in adults. However, the national impact of the vaccination program on COVID-19 in children remains unknown. To determine the association of COVID-19 vaccination with U.S. case incidence, emergency department visits, and hospital admissions for pediatric populations during the Delta and Omicron periods. We conducted an ecological analysis among children aged 5-17 and compared incidence rate ratios (RRs) of COVID-19 cases, emergency department visits, and hospital admissions by pediatric vaccine coverage, with jurisdictions in the highest vaccine coverage quartile as the reference. RRs comparing states with lowest pediatric vaccination coverage to the highest pediatric vaccination coverage were 2.00 and 0.64 for cases, 2.96 and 1.11 for emergency department visits, and 2.76 and 1.01 for hospital admissions among all children during the Delta and Omicron periods, respectively. During the 3-week peak period of the Omicron wave, only children aged 12-15 and 16-17 years in the states with the lowest versus highest coverage, had a significantly higher rate of emergency department visits (RR = 1.39 and RR = 1.34, respectively). COVID-19 vaccines were associated with lower case incidence, emergency department visits and hospital admissions among children during the Delta period but the association was weaker during the Omicron period. Pediatric COVID-19 vaccination should be promoted as part of a program to decrease COVID-19 impact among children; however, vaccine effectiveness may be limited when available vaccines do not match circulating viral variants.

In the USA, COVID-19 vaccines became available in mid-December, 2020, with adults aged 65 years and older among the first groups prioritised for vaccination. We estimated the national-level impact of the initial phases of the US COVID-19 vaccination programme on COVID-19 cases, emergency department visits, hospital admissions, and deaths among adults aged 65 years and older. We analysed population-based data reported to US federal agencies on COVID-19 cases, emergency department visits, hospital admissions, and deaths among adults aged 50 years and older during the period Nov 1, 2020, to April 10, 2021. We calculated the relative change in incidence among older age groups compared with a younger reference group for pre-vaccination and post-vaccination periods, defined by the week when vaccination coverage in a given age group first exceeded coverage in the reference age group by at least 1%; time lags for immune response and time to outcome were incorporated. We assessed whether the ratio of these relative changes differed when comparing the pre-vaccination and post-vaccination periods. The ratio of relative changes comparing the change in the COVID-19 case incidence ratio over the post-vaccine versus pre-vaccine periods showed relative decreases of 53% (95% CI 50 to 55) and 62% (59 to 64) among adults aged 65 to 74 years and 75 years and older, respectively, compared with those aged 50 to 64 years. We found similar results for emergency department visits with relative decreases of 61% (52 to 68) for adults aged 65 to 74 years and 77% (71 to 78) for those aged 75 years and older compared with adults aged 50 to 64 years. Hospital admissions declined by 39% (29 to 48) among those aged 60 to 69 years, 60% (54 to 66) among those aged 70 to 79 years, and 68% (62 to 73), among those aged 80 years and older, compared with adults aged 50 to 59 years. COVID-19 deaths also declined (by 41%, 95% CI –14 to 69 among adults aged 65–74 years and by 30%, –47 to 66 among those aged ≥75 years, compared with adults aged 50 to 64 years), but the magnitude of the impact of vaccination roll-out on deaths was unclear. The initial roll-out of the US COVID-19 vaccination programme was associated with reductions in COVID-19 cases, emergency department visits, and hospital admissions among older adults. None.

Background Essential services ensure the health, safety, and well-being of individuals and their communities. However, there is currently a lack of consensus on what constitutes an essential service in Australia. This gap hinders a detailed spatial understanding of essential service provision, access, and influence on populations. This systematic review critically assessed the literature on essential services and their impact on quality of life to understand service definitions and their relative contributions to quality of life. Methods A systematic search of ten databases was undertaken following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. Five criteria were established for the inclusion of studies: (i) major developed economies, (ii) defined essential service and focus on spatial access, (iii) quality of life outcome, (iv) peer-reviewed, and (v) published between 2000 and 2024. Results From 1,473 unique records, seven studies met the inclusion criteria, with studies from Europe, Asia-Pacific, and North America. Across the studies, services were characterised based on their primary function and contributions to quality of life. Service categories included food, retail, personal services, health, education, culture and recreation, and faith-based services. Despite demographic and scale variations, services that fostered social connection and a sense of place showed the highest positive impact on quality of life. Conclusions Findings indicate limited and inconsistent evidence on essential service measures and their relationship with quality of life. The persistent lack of justification for classifying services as essential in research hinders definitive conclusions about which services most effectively enhance quality of life. Future research should adopt standardised, validated measures, and address representation gaps across diverse populations and regions. This work is fundamental for developing a validated set of essential services, to improve national modelling of geographic access and inform policy, decision-making, and understanding of how access to services influences quality of life.

Objectives To undertake a qualitative evaluation of the implementation of the Penile and Testicular cancer multidisciplinary meeting (PEN-TEST MDM) model pilot including the acceptability, adoption, appropriateness, feasibility, and requirements for sustaining the model from the perspectives of key informants. Design, setting, participants A qualitative evaluation of the PEN-TEST MDM model six-month implementation pilot at Barwon Health (Victoria, Australia) (January to July 2024) was undertaken from July to September 2024. Qualitative data was obtained from semi-structured interviews undertaken with key informants, including working group members and end-users (referring and attending clinicians). Data was analysed abductively and reported, guided by Proctor’s implementation outcomes framework. Main outcome measures Key themes pertaining to implementation outcomes based on qualitative analysis. Results Thirteen key informants were interviewed. Three key concepts were developed: (1) value for the clinician workforce: acceptability and adoption, (2) optimising patient care: appropriateness and feasibility, and (3) considerations for sustainability and scalability. Conclusions The PEN-TEST MDM model is a promising approach for reviewing patient cases with penile or testicular cancer. Findings support the importance of ongoing stakeholder engagement to shape the next iteration, and further investment to refine, sustain, and scale the model. Subject to this, scoping opportunities for scaling to other less common or rare cancers is warranted. The MDM model established has potential to be transformative in addressing inequitable access to specialist cancer care.

Throughout the COVID-19 pandemic, older U.S. adults have been at increased risk for severe COVID-19-associated illness and death (1). On December 14, 2020, the United States began a nationwide vaccination campaign after the Food and Drug Administration's Emergency Use Authorization of Pfizer-BioNTech COVID-19 vaccine. The Advisory Committee on Immunization Practices (ACIP) recommended prioritizing health care personnel and residents of long-term care facilities, followed by essential workers and persons at risk for severe illness, including adults aged ≥65 years, in the early phases of the vaccination program (2). By May 1, 2021, 82%, 63%, and 42% of persons aged ≥65, 50-64, and 18-49 years, respectively, had received ≥1 COVID-19 vaccine dose. CDC calculated the rates of COVID-19 cases, emergency department (ED) visits, hospital admissions, and deaths by age group during November 29-December 12, 2020 (prevaccine) and April 18-May 1, 2021. The rate ratios comparing the oldest age groups (≥70 years for hospital admissions; ≥65 years for other measures) with adults aged 18-49 years were 40%, 59%, 65%, and 66% lower, respectively, in the latter period. These differential declines are likely due, in part, to higher COVID-19 vaccination coverage among older adults, highlighting the potential benefits of rapidly increasing vaccination coverage.Throughout the COVID-19 pandemic, older U.S. adults have been at increased risk for severe COVID-19-associated illness and death (1).

Atherosclerosis is a chronic disease of the vascular wall driven by lipid accumulation and inflammation in the intimal layer of arteries, and its main complications—myocardial infarction and stroke—are the leading cause of mortality worldwide 1,2 . Recent studies have identified triggering receptor expressed on myeloid cells 2 (TREM2), a lipid-sensing receptor regulating myeloid cell functions 3 , to be highly expressed in macrophage foam cells in experimental and human atherosclerosis 4 . However, the role of TREM2 in atherosclerosis is not fully known. Here we show that hematopoietic or global TREM2 deficiency increased, whereas TREM2 agonism decreased, necrotic core formation in early atherosclerosis. We demonstrate that TREM2 is essential for the efferocytosis capacities of macrophages and to the survival of lipid-laden macrophages, indicating a crucial role of TREM2 in maintaining the balance between foam cell death and clearance of dead cells in atherosclerotic lesions, thereby controlling plaque necrosis.

Background Optimized symptom-based COVID-19 case definitions that guide public health surveillance and individual patient management in the community may assist pandemic control. Methods We assessed diagnostic performance of existing cases definitions (e.g. influenza-like illness, COVID-like illness) using symptoms reported from 185 household contacts to a PCR-confirmed case of COVID-19 in Wisconsin and Utah, United States. We stratified analyses between adults and children. We also constructed novel case definitions for comparison. Results Existing COVID-19 case definitions generally showed high sensitivity (86–96%) but low positive predictive value (PPV) (36–49%; F-1 score 52–63) in this community cohort. Top performing novel symptom combinations included taste or smell dysfunction and improved the balance of sensitivity and PPV (F-1 score 78–80). Performance indicators were generally lower for children (< 18 years of age). Conclusions Existing COVID-19 case definitions appropriately screened in household contacts with COVID-19. Novel symptom combinations incorporating taste or smell dysfunction as a primary component improved accuracy. Case definitions tailored for children versus adults should be further explored.

The recently launched Illumina Infinium MethylationEPIC v2.0 (EPICv2), successor of MethylationEPIC v1.0 (EPICv1), retains most of the probes in EPICv1, while expanding coverage of regulatory elements. The concordance between the two EPIC versions in DNA methylation–based tools has not yet been investigated. To address this, DNA methylation was profiled on both versions using matched blood samples across four cohorts spanning early to late adulthood. High concordance between versions at the array level but variable agreement at the individual probe level was noted. A significant contribution of the EPIC version to DNA methylation variation was observed, though it was to a smaller extent compared with sample relatedness and cell-type composition. Modest but significant differences in DNA methylation–based estimates between versions were observed, irrespective of the data preprocessing method used. Adjustments for EPIC version or calculation of estimates separately for each version largely mitigated these version-specific discordances. This work emphasizes the importance of accounting for EPIC version differences in research scenarios, especially in meta-analyses and longitudinal studies that require data harmonization across versions.
