OBJECTIVES: To determine the impact of increased long-acting injectable antiretroviral therapy (Cabotegravir-rilpivirine [CAB/RPV]) use among persons with diagnosed HIV (PWDH) with viral suppression (VLS), per 2021 US Food and Drug Administration (FDA) guidelines, on HIV incidence and levels of VLS in the US. METHODS: We used the HOPE compartmental model to simulate CAB/RPV use during 2023-2035. We first simulated a baseline scenario (no CAB/RPV), in which 69% of PWDH had VLS. We then introduced CAB/RPV in 2023 under two scenarios: (1) where CAB/RPV improved the duration of VLS post-cessation of ART use compared to oral ART; (2) where CAB/RPV additionally improved adherence. We compared cumulative 2023-35 incidence and percentage of PWDH with VLS at year-end 2035 to baseline. RESULTS: When CAB/RPV increased the duration of VLS only, cumulative incidence was reduced up to 9%, and VLS increased up to 4%. When CAB/RPV also improved ART adherence, incidence was reduced up to 19.5%, and VLS increased up to 9%. CONCLUSIONS: CAB/RPV, even if only used among PWDH with VLS, may reduce HIV incidence and increase VLS, due to longer-lasting VLS post-cessation of usage. If CAB/RPV also improves ART adherence, incidence is further reduced. Improved clinical efficacy of CAB/RPV may translate to improved population-level outcomes, even in limited use cases.

For about two decades, the U.S. health care system was making strides in improving patient safety, as demonstrated by the reduction of health care–associated infections and other complications of care.1 Though there was still room for improvement, the trends were certainly in the right direction. Since the Covid-19 pandemic began, however, many indicators make it clear that health care safety has declined. The public health emergency has put enormous stress on the health care system and disrupted many normal activities in hospitals and other facilities. Unfortunately, these stressors have caused safety problems for both patients and staff. Managing the competing priorities of providing care for large numbers of patients with Covid, as well as for the patients without Covid who need care every day, and of maintaining safety efforts such as robust infection-control practices is both difficult and essential.

Sarcoidosis and chronic beryllium disease (CBD) are phenocopies, however the latter one has a clear trigger factor that is beryllium exposure. This study analyses single nucleotide polymorphisms (SNPs) in a large cohort for beryllium-exposed persons. SNPs were chosen for their relevance in sarcoidosis. Even though one of largest cohorts of beryllium-exposed persons was analysed, no statistically relevant association between any SNP and CBD could be verified. Notably, some SNPs exhibit inverse OR for beryllium sensitization and CBD with nominally statistical significance, which allows hypothesizing about pathophysiological role of genes for the disease triggering and development.

Peritoneal dialysis (PD)-associated peritonitis is the leading cause of permanent transition to hemodialysis among patients receiving PD. Peritonitis is associated with higher mortality risk and added treatment costs and limits more widespread PD utilization. Optimizing the prevention of peritonitis in the United States will first require standardization of peritonitis definitions, key data elements, and outcomes in an effort to facilitate nationwide reporting. Standardized reporting can also help describe the variability in peritonitis rates and outcomes across facilities in the United States in an effort to identify potential peritonitis prevention strategies and engage with stakeholders to develop strategies for their implementation. Here, we will highlight considerations and challenges in developing standardized definitions and implementation of national reporting of peritonitis rates by PD facilities. We will describe existing peritonitis prevention evidence gaps, highlight successful infection-reporting initiatives among patients receiving in-center hemodialysis or PD, and provide an overview of nationwide quality improvement initiatives, both in the United States and elsewhere, that have translated into a reduction in peritonitis incidence. We will discuss opportunities for collaboration and expansion of the Nephrologists Transforming Dialysis Safety (NTDS) initiative to develop knowledge translation pathways that will lead to dissemination of best practices in an effort to reduce peritonitis incidence.

Mycobacterial infection-related morbidity and mortality in patients following cardiopulmonary bypass surgery is high and and there is a growing need for a consensus-based expert opinion to provide international guidance for diagnosing, preventing and treating in these patients. In this document the International Society for Cardiovascular Infectious Diseases (ISCVID) covers aspects of prevention (field of hospital epidemiology), clinical management (infectious disease specialists, cardiac surgeons, ophthalmologists, others), laboratory diagnostics (microbiologists, molecular diagnostics), device management (perfusionists, cardiac surgeons) and public health aspects.

There is increasing knowledge that health care workers (HCWs) can experience a variety of emotional impacts when responding to disasters and terrorism events. The Anticipate, Plan and Deter (APD) Responder Risk and Resilience Model was developed to provide a new, evidence-informed method for understanding and managing psychological impacts among HCWs. APD includes pre-deployment development of an individualized resilience plan and an in-theater, real-time self-triage system, which together allow HCWs to assess and manage the full range of psychological risk and resilience for themselves and their families. The inclusion of objective mental health risk factors to prompt activation of a coping plan, in connection with unit leadership real-time situational awareness, enables the first known evidence-driven "targeted action" plan to address responder risk early before Post Traumatic Stress Disorder and impairment become established. This paper describes pilot work using the self-triage system component in Alameda County's Urban Shield and the Philippines' Typhoon Haiyan, and then reports a case example of the full APD model implementation in West Africa's Ebola epidemic.

Aspergillus spp. are the most common invasive mold infection and are responsible for high mortality. A. fumigatus is currently of interest because resistance to azole antifungals has emerged. The Campinas University Hospital (HC-UNICAMP) receives high-risk patients susceptible to opportunistic infections but there have been no reports of resistant A. fumigatus. This study aimed to assess the susceptibility profile of Aspergillus isolates, specifically looking for azole resistance. ITS and beta-tubulin DNA sequencing was performed on 228 sequential clinical isolates. Broth microdilution susceptibility testing was performed for all isolates. A. fumigatus represented 74% of the isolates followed by A. flavus (12%). Nine A. fumigatus isolates from 9 different patients showed high MIC values to at least one azole, but cyp51A polymorphisms were detected in only 6 isolates and none correlated with known resistance mutations. The most troubling observation was that the minimum inhibitory concentration for amphotericin B was elevated (>/=2 mg L(-1) ) in 87% of patients with A. flavus isolates and 43% with A. fumigatus isolates. Given that amphotericin B is used to treat azole resistant infections, these data highlight the need for continuous surveillance in Aspergillus for all antifungal resistance to implement correct treatment strategies for the management of these pathogens.

On August 24, 2014, at 3:20 a.m., a magnitude 6.0 earthquake struck California, with its epicenter in Napa County (1). The earthquake was the largest to affect the San Francisco Bay area in 25 years and caused significant damage in Napa and Solano counties, including widespread power outages, five residential fires, and damage to roadways, waterlines, and 1,600 buildings (2). Two deaths resulted (2). On August 25, Napa County Public Health asked the California Department of Public Health (CDPH) for assistance in assessing postdisaster health effects, including earthquake-related injuries and effects on mental health. On September 23, Solano County Public Health requested similar assistance. A household-level Community Assessment for Public Health Emergency Response (CASPER) was conducted for these counties in two cities (Napa, 3 weeks after the earthquake, and Vallejo, 6 weeks after the earthquake). Among households reporting injuries, a substantial proportion (48% in Napa and 37% in western Vallejo) reported that the injuries occurred during the cleanup period, suggesting that increased messaging on safety precautions after a disaster might be needed. One fifth of respondents overall (27% in Napa and 9% in western Vallejo) reported one or more traumatic psychological exposures in their households. These findings were used by Napa County Mental Health to guide immediate-term mental health resource allocations and to conduct public training sessions and education campaigns to support persons with mental health risks following the earthquake. In addition, to promote community resilience and future earthquake preparedness, Napa County Public Health subsequently conducted community events on the earthquake anniversary and provided outreach workers with psychological first aid training.

Botulism is a severe neurological disease caused by the complex family of botulinum neurotoxins (BoNT). Based on the different serotypes known today, a classification of serotype variants termed subtypes has been proposed according to sequence diversity and immunological properties. However, the relevance of BoNT subtypes is currently not well understood. Here we describe the isolation of a novel Clostridium botulinum strain from a food-borne botulism outbreak near Chemnitz, Germany. Comparison of its botulinum neurotoxin gene sequence with published sequences identified it to be a novel subtype within the BoNT/A serotype designated BoNT/A8. The neurotoxin gene is located within an ha-orfX+ cluster and showed highest homology to BoNT/A1, A2, A5, and A6. Unexpectedly, we found an arginine insertion located in the HC domain of the heavy chain, which is unique compared to all other BoNT/A subtypes known so far. Functional characterization revealed that the binding characteristics to its main neuronal protein receptor SV2C seemed unaffected, whereas binding to membrane-incorporated gangliosides was reduced in comparison to BoNT/A1. Moreover, we found significantly lower enzymatic activity of the natural, full-length neurotoxin and the recombinant light chain of BoNT/A8 compared to BoNT/A1 in different endopeptidase assays. Both reduced ganglioside binding and enzymatic activity may contribute to the considerably lower biological activity of BoNT/A8 as measured in a mouse phrenic nerve hemidiaphragm assay. Despite its reduced activity the novel BoNT/A8 subtype caused severe botulism in a 63-year-old male. To our knowledge, this is the first description and a comprehensive characterization of a novel BoNT/A subtype which combines genetic information on the neurotoxin gene cluster with an in-depth functional analysis using different technical approaches. Our results show that subtyping of BoNT is highly relevant and that understanding of the detailed toxin function might pave the way for the development of novel therapeutics and tailor-made antitoxins.

CONTEXT: Rapid mental health surveillance during the acute phase of a disaster response can inform the allocation of limited clinical resources and provide essential household-level risk estimates for recovery planning. OBJECTIVE: To describe the use of the PsySTART Rapid Mental Health Triage and Incident Management System for individual-level clinical triage and traumatic exposure assessment in the aftermath of a large-scale disaster. METHODS: We conducted a cross-sectional, comparative review of mental health triage data collected with the PsySTART system from survivors of the September 2009 earthquake-tsunami in American Samoa. Data were obtained from two sources-secondary triage of patients and a standardized community assessment survey-and analyzed descriptively. The main outcome measures were survivor-reported traumatic experiences and exposures-called triage factors-associated with risk for developing severe distress and new mental health disorders following disasters. RESULTS: The most common triage factors reported by survivors referred for mental health services were "felt extreme panic/fear" (93%) and "felt direct threat to life" (93%). The most common factor reported by persons in tsunami-affected communities was "felt extreme panic or fear" (75%). Proportions of severe triage factors reported by persons living in the community were consistently lower than those reported by patients referred for mental health services. CONCLUSIONS: The combination of evidence-based mental health triage and community assessment gave hospital-based providers, local public health officials, and federal response teams a strategy to match limited clinical resources with survivors at greatest risk. Also, it produced a common operating picture of acute and chronic mental health needs among disaster systems of care operating in American Samoa.
