Single-arm study of testosterone gel replacement therapy and ambulatory blood pressure outcomes in men with hypogonadism.

BACKGROUND AND OBJECTIVE: Studies examining ambulatory blood pressure (BP) response to testosterone replacement therapy are needed owing to inconsistent prior findings across formulations. This study assessed testosterone gel 1.62% and 24-h ambulatory BP. MATERIALS AND METHODS: Single-arm non-inferiority trial (NCT04274894) conducted at 36 US sites enrolled 246 men with hypogonadism (mean age, 57.6 years; mean office systolic/diastolic BP [SBP/DBP], 129.8/79.5 mm Hg) who were treated for 16 weeks with once-daily testosterone gel treatment (starting dose, 40.5 mg/day; min, max dose, 20.25, 81.0 mg/day) to achieve testosterone concentration of 350-750 ng/dL. Main outcome measures included mean change in 24-h average SBP (primary endpoint) and DBP from baseline to week 16. The non-inferiority threshold was a two-sided 95% confidence interval (CI) upper limit <3.0 mm Hg for 24-h average SBP. RESULTS: Increase in mean ± SD serum testosterone concentration to a physiologic level (baseline, 244.4 ± 93.9 ng/dL; week 16, 502.5 ± 394.4 ng/dL) was associated with a 1.9-mm Hg mean change in 24-h average SBP observed in the primary analysis (baseline, 123.5 mm Hg; week 16, 125.4 mm Hg; 95% CI, 0.63-3.13 mm Hg; n = 169). As the upper CI limit modestly exceeded the non-inferiority margin (3 mm Hg), study drug effect on SBP could not be ruled out. Non-inferiority was observed in subgroups without hypertension or diabetes (95% CI, upper limit <3.0 mm Hg) and was not observed in those with hypertension or diabetes. Daytime SBP and DBP changes were larger compared with nighttime. No clear cardiovascular adverse events or new safety signals were identified. DISCUSSION AND CONCLUSIONS: While the effect of testosterone gel 1.62% on 24-h average SBP could not be ruled out based on the study's non-inferiority margin, the clinical relevance of the small-magnitude mean increase of 1.9 mm Hg is anticipated to be minimal considering the results of the TRAVERSE study of testosterone gel 1.62% and major adverse cardiac events.

Targeting the host transcription factor HSF1 prevents human cytomegalovirus replication in vitro and in vivo.

FDA-approved antivirals against HCMV have several limitations, including only targeting the later stages of the viral replication cycle, adverse side effects, and the emergence of drug-resistant strains. Antivirals targeting host factors specifically activated within infected cells and necessary for viral replication could address the current drawbacks of anti-HCMV standard-of-care drugs. In this study, we found HCMV infection stimulated the activation of the stress response transcription factor heat shock transcription factor 1 (HSF1). HCMV entry into fibroblasts rapidly increased HSF1 activity and subsequent relocalization from the cytoplasm to the nucleus, which was maintained throughout viral replication and in contrast to the transient burst of activity induced by canonical heat shock. Prophylactic pharmacological inhibition or genetic depletion of HSF1 prior to HCMV infection attenuated the expression of all classes of viral genes, including immediate early (IE) genes, and virus production, suggesting HSF1 promotes the earliest stages of the viral replication cycle. Therapeutic treatment with SISU-102, an HSF1 inhibitor tool compound, after IE expression also reduced the levels of L proteins and progeny production, suggesting HSF1 regulates multiple steps along the HCMV replication cycle. Leveraging a newly developed human skin xenograft transplant murine model, we found prophylactic treatment with SISU-102 significantly attenuated viral replication in transplanted human skin xenografts as well as viral dissemination to distal sites. These data demonstrate HCMV infection rapidly activates and relocalizes HSF1 to the nucleus to promote viral replication, which can be exploited as a host-directed antiviral strategy. One Sentence Summary: Inhibiting of HSF1 as a host-directed antiviral therapy attenuates HCMV replication in vitro and in vivo.

Reinterpreting Chronic Wasting Disease Emergence in the USA in Light of Historical Surveillance Limitations.

We estimated the probabilities of detecting one or more chronic wasting disease (CWD) cases (Pdet) in free-ranging cervids in the continental US during 1997 - 2001. Based on sample sizes reported by respective state authorities at the time and a target for detectable apparent prevalence (i.e., a design prevalence) of 0.001 (one positive per 1,000 animals statewide), estimated Pdet were <50% for 39/46 states where CWD had not been detected in the wild prior to 1997 and were <5% in 20/26 states located east of the Mississippi River. The survey designs and sample sizes reported by most states prior to 2002 would have yielded exceedingly small detection probabilities for focal CWD outbreaks. Although most CWD foci in the US were first detected in 2002 or after, the data presented here and elsewhere suggest it is plausible that an unknown number of these-some established perhaps decades earlier-were already present but had simply eluded detection. These data highlight uncertainty regarding timelines for CWD emergence in the US. Accepting-and to the extent possible quantifying-uncertainty in the historical distribution of CWD throughout the US seems a necessary foundation for better understanding its emergence, its drivers and patterns of spread, and its response to various interventions-past, present, and future.

Restless Leg Syndrome and Its Relation to Mirtazapine: A Case Report.

Major depressive disorder (MDD) and Restless legs syndrome (RLS) present complex clinical challenges, often coexisting and complicating treatment strategies. While the relationship between MDD and RLS remains somewhat elusive, emerging evidence suggests a potential interplay between antidepressant medications and the worsening of RLS symptoms. This case report illuminates an instance where mirtazapine, a tetracyclic antidepressant commonly used in MDD, precipitated a resurgence of RLS symptoms in a patient with a previously controlled presentation.

A novel dual probe-based method for mutation detection using isothermal amplification.

Cost efficient and rapid detection tools to detect mutations especially those linked to drug-resistance are important to address concerns of the rising multi-drug resistance infections. Here we integrated dual probes, namely a calibrator probe and an indicator probe, into isothermal amplification detection system. These two probes are designed to bind distinct regions on the same amplicon to determine the presence or absence of mutation. The calibrator probe signal is used as an internal signal calibrator for indicator probe which detects the presence or absence of the mutation. As an illustrative example, we evaluated the applicability of this dual probe method for detecting mutations associated with rifampicin (RIF) drug resistance at codons 516, 526 and 531 of the rpoB gene in Mycobacterium tuberculosis. In this assessment, we examined 127 artificial samples comprising wild types and mutants with single or multiple mutations. Our results demonstrated 100% accuracy for both wild types and mutants for mutations at codons 526 and 531. As regards to mutations at codon 516, the wild type was identified with 100% accuracy, while the mutants were identified with 95% accuracy. Moreover, when we extended our evaluation to include clinical MTB strains and the Zeptometrix MTB Verification panel, our method achieved 100% accuracy (5 out of 5) in identifying wild-type strains. Additionally, we successfully detected a RIF-resistant strain with mutations at codon 531 of the rpoB gene in Zeptometrix verification panel. Our isothermal mutation detection system, relying on dual probes exhibits a versatile approach. With the capability to identify mutations without prior knowledge of their specific mutation direction, our dual-probe method shows significant promise for applications in drug resistance nucleic acid testing, particularly in resource-limited settings.

HSV-1 Infection Alters MAPT Splicing and Promotes Tau Pathology in Neural Models of Alzheimer's Disease.

INTRODUCTION: Herpes simplex virus 1 (HSV-1) infection alters critical markers of Alzheimer's Disease (AD) in neurons. One key marker of AD is the hyperphosphorylation of Tau, accompanied by altered levels of Tau isoforms. However, an imbalance in these Tau splice variants, specifically resulting from altered 3R to 4R MAPT splicing of exon 10, has yet to be directly associated with HSV-1 infection. METHODS: To this end, we infected 2D and 3D human neural models with HSV-1 and monitored MAPT splicing and Tau phosphorylation. Further, we transduced SH-SY5Y-neurons with HSV-1 ICP27 which alters RNA splicing to analyze if ICP27 alone is sufficient to induce altered MAPT exon 10 splicing. RESULTS: We show that HSV-1 infection induces altered splicing of MAPT exon 10, increasing 4R-Tau protein levels, Tau hyperphosphorylation, and Tau oligomerization. DISCUSSION: Our experiments reveal a novel link between HSV-1 infection and the development of cytopathic phenotypes linked with AD progression. HIGHLIGHTS: HSV-1 infection in forebrain organoids reduces the neurite length of MAP2-positive neurons.HSV-1 infection increases Tau hyperphosphorylation in both two-month-old and four-month-old forebrain organoids. HSV-1 infection increases Exon 10 containing (4R) MAPT mRNA and 4R-Tau protein expression in both forebrain organoids and human SH-SY5Y-neurons. HSV-1 ICP27 is both necessary and sufficient to induce increased 4R MAPT mRNA and 4R-Tau protein expression in SH-SY5Y-neurons. HSV-1 infection increases Tau oligomerization in both forebrain organoids and SH-SY5Y-neurons.

Paramedic educational programs maintain entry level competency throughout the COVID-19 pandemic.

Objective: The COVID-19 pandemic required unprecedented changes to emergency medical services (EMS) educational frameworks in the United States. It is unclear if pandemic-related changes impacted paramedic educational outcomes. We aimed to evaluate curricular and performance changes resulting from the initial COVID-19 pandemic on paramedic educational programs. Methods: We performed a retrospective cross-sectional evaluation of paramedic educational programs in 2019 and 2020 using the Committee on Accreditation of Educational Programs for the Emergency Medical Services Professions annual reports. These reports contain detailed program components and measures of program success. We included programs reporting at least one graduate in the study period. Descriptive statistics (proportions [%], median [interquartile range, IQR]) were calculated for paramedic program characteristics in 2019 and 2020, as well as pandemic specific curriculum changes. Wilcoxon rank-sum and Fisher's exact tests were used to evaluate differences in characteristics by year. Results: The number of paramedic educational programs in our population decreased from 640 programs in 2019 to 612 in 2020, with a statistically significant decrease in clinical hours (2019: 219 [IQR 168‒272]; 2020: 200.5 [IQR 157‒261]). There was no difference in first or third-attempt certification examination success between years. Temporary shutdown was experienced in 34% of programs (duration: 3 weeks [2‒7]) and 72% of required curricular changes. Curricular changes commonly included decreased in-person education (86%), traditional classroom lectures (78%), number of clinical sites (78%), and increased online didactic education (92%). Only 20% of programs decreased laboratory simulation or total training hours. Conclusion: During the pandemic, paramedic educational programs changed educational delivery with no observed differences on overall program performance. Identifying key curricular changes and best practices for implementation may be necessary to better optimize future educational delivery.

Cryo-EM structure of a natural prion: chronic wasting disease fibrils from deer.

Chronic wasting disease (CWD) is a widely distributed prion disease of cervids with implications for wildlife conservation and also for human and livestock health. The structures of infectious prions that cause CWD and other natural prion diseases of mammalian hosts have been poorly understood. Here we report a 2.8 Å resolution cryogenic electron microscopy-based structure of CWD prion fibrils from the brain of a naturally infected white-tailed deer expressing the most common wild-type PrP sequence. Like recently solved rodent-adapted scrapie prion fibrils, our atomic model of CWD fibrils contains single stacks of PrP molecules forming parallel in-register intermolecular ß-sheets and intervening loops comprising major N- and C-terminal lobes within the fibril cross-section. However, CWD fibrils from a natural cervid host differ markedly from the rodent structures in many other features, including a ~ 180° twist in the relative orientation of the lobes. This CWD structure suggests mechanisms underlying the apparent CWD transmission barrier to humans and should facilitate more rational approaches to the development of CWD vaccines and therapeutics.

Pulse wave velocity as a tool for cardiometabolic risk stratification in individuals with hypertensive disorders of pregnancy and increased BMI.

OBJECTIVE: Obesity is one of the most prevalent risk factors for hypertensive disorders in pregnancy (HDP); however, the role of pre-pregnancy cardiometabolic health in the development of these conditions is not well understood. Carotid-femoral pulse wave velocity (PWV) is an established measure of arterial stiffness and cardiovascular health and is validated in pregnancy. Our objective was to examine the obesity-related changes in PWV in pregnant individuals with and without HDP. METHODS: Eighty-seven individuals with singleton pregnancies were recruited and classified into two groups: cases (HDP: including pre-existing/chronic hypertension, gestational hypertension, preeclampsia, or intrauterine growth restriction (IUGR); n = 39) and normotensive controls (no HDP or IUGR; n = 48). Patient data, including body mass index (BMI), were collected from patient charts. Measurements of PWV were performed weekly until discharge or delivery (gestational age 24-37 weeks) and placental growth factor (PlGF) was measured at routine blood draws. RESULTS: PWV did not significantly change over gestation for either group. Cases had significantly increased PWV and decreased PlGF compared to normotensive controls. An elevated BMI was associated with higher PWV in both cases and controls. Once grouped based on BMI, PWV was only significantly higher in cases with a BMI ≥ 25 kg/m2 compared to controls, whereas PlGF was less affected by BMI. As PWV increased, PlGF decreased; however, after controlling for BMI, there was no relationship between PWV and PlGF. CONCLUSION: PWV measurements in early pregnancy may be useful as an additional independent marker to PlGF for risk-stratifying for HDP, especially in individuals with increased BMI.

Post-tuberculosis lung disease: Addressing the policy gap.

The burden of long-term functional impairment following curative treatment for tuberculosis (TB) constitutes a significant global health problem. By some estimates, chronic respiratory impairment, or post-tuberculosis lung disease (PTLD), is present in just over half of all patients who have completed TB therapy. Despite this high prevalence and substantial associated morbidity, discussion of PTLD is essentially absent from international and national TB policies and guidelines. Clear and ambitious clinical standards should be established for the diagnosis and management of PTLD, including the stipulation that all patients completing TB therapy should be screened for PTLD. Patients diagnosed with PTLD should receive linkage to chronic care, with access to inhalers and home oxygen, as indicated based on individual symptoms and pathophysiology. Leveraging their considerable influence, major funders, such as The Global Fund, could help close the gap in PTLD care by including PTLD in their strategic vision and funding streams. Immediate action is needed to address the substantial burden of disease associated with PTLD. This will require expanding the global approach to TB to include a commitment to diagnosing and treating long-term complications following initial curative therapy.

The impact of climate variation on the spread of Shiga toxin-producing E. coli.

BACKGROUND: Shiga toxin-producing Escherichia coli (STEC) is influenced by seasonality, but there is limited understanding of how specific climatic variables contribute to disease spread. This information aids in understanding disease transmission dynamics and could potentially inform public health modeling. METHODS: This retrospective cohort study analyzed public health data from Ontario, Canada, between 2012 and 2021, along with historical climate data from Environment Canada. We employed Seasonal Autoregressive Integrated Moving Average (S-ARIMA) models to assess how temperature and precipitation impact the incidence of STEC infections, measured per 10,000,000 population. RESULTS: The study included 1658 confirmed STEC cases. A significant correlation was found between STEC incidence and climatic variables. Each degree Celsius increase in maximum temperature was associated with a rise of 3 STEC cases per 10,000,000 population (Centers for Disease Control and Prevention (2024)). Additionally, each millimeter of increased precipitation correlated with an increase of 1.1 cases per 10,000,000 population. CONCLUSIONS: The findings demonstrate a significant impact of temperature and precipitation on STEC transmission, highlighting the importance of integrating meteorological data into public health surveillance. This integration may help inform public health responses and support healthcare systems in planning for future outbreaks. Further studies are needed to refine predictive models and develop effective early warning systems for clinical settings.

Genomic prediction for potato (Solanum tuberosum) quality traits improved through image analysis.

Potato (Solanum tuberosum L.) is the most widely grown vegetable in the world. Consumers and processors evaluate potatoes based on quality traits such as shape and skin color, making these traits important targets for breeders. Achieving and evaluating genetic gain is facilitated by precise and accurate trait measures. Historically, quality traits have been measured using visual rating scales, which are subject to human error and necessarily lump individuals with distinct characteristics into categories. Image analysis offers a method of generating quantitative measures of quality traits. In this study, we use TubAR, an image-analysis R package, to generate quantitative measures of shape and skin color traits for use in genomic prediction. We developed and compared different genomic models based on additive and additive plus non-additive relationship matrices for two aspects of skin color, redness, and lightness, and two aspects of shape, roundness, and length-to-width ratio for fresh market red and yellow potatoes grown in Minnesota between 2020 and 2022. Similarly, we used the much larger chipping potato population grown during the same time to develop a multi-trait selection index including roundness, specific gravity, and yield. Traits ranged in heritability with shape traits falling between 0.23 and 0.85, and color traits falling between 0.34 and 0.91. Genetic effects were primarily additive with color traits showing the strongest effect (0.47), while shape traits varied based on market class. Modeling non-additive effects did not significantly improve prediction models for quality traits. The combination of image analysis and genomic prediction presents a promising avenue for improving potato quality traits.

Synthetic Colonic Mucus Enables the Development of Modular Microbiome Organoids.

The human colon is home to trillions of microorganisms that modulate gastrointestinal physiology. Our understanding of how this gut ecosystem impacts human health, although evolving, has been slowed by the lack of accessible tools suitable to studying complex host-mucus-microbe interactions. Here, we report a synthetic gel-like material capable of recapitulating the varied structural, mechanical, and biochemical profiles of native human colonic mucus to develop compositionally simple microbiome screening platforms with utility in microbiology and drug discovery. The viscous fibrillar material is realized through templated assembly of a fluorine-rich amino acid at liquid-liquid interphases. The fluorine-assisted mucus surrogate (FAMS) can be decorated with mucins to serve as a habitat for microbial colonization and integrated with human colorectal cells to generate artificial mucosae, referred to as a microbiome organoid. Notably, FAMS are made with inexpensive and commercially available materials, and can be generated using simple protocols and standard laboratory hardware. As a result, this platform can be broadly incorporated into various laboratory settings to advance probiotic research and inform in vivo approaches. If implemented into high throughput screening approaches, FAMS may represent a valuable tool to study compound metabolism and gut permeability, with an exemplary demonstration of this utility presented here.

Single cell multiome profiling of pancreatic islets reveals physiological changes in cell type-specific regulation associated with diabetes risk.

Physiological variability in pancreatic cell type gene regulation and the impact on diabetes risk is poorly understood. In this study we mapped gene regulation in pancreatic cell types using single cell multiomic (joint RNA-seq and ATAC-seq) profiling in 28 non-diabetic donors in combination with single cell data from 35 non-diabetic donors in the Human Pancreas Analysis Program. We identified widespread associations with age, sex, BMI, and HbA1c, where gene regulatory responses were highly cell type- and phenotype-specific. In beta cells, donor age associated with hypoxia, apoptosis, unfolded protein response, and external signal-dependent transcriptional regulators, while HbA1c associated with inflammatory responses and gender with chromatin organization. We identified 10.8K loci where genetic variants were QTLs for cis regulatory element (cRE) accessibility, including 20% with lineage- or cell type-specific effects which disrupted distinct transcription factor motifs. Type 2 diabetes and glycemic trait associated variants were enriched in both phenotype- and QTL-associated beta cell cREs, whereas type 1 diabetes showed limited enrichment. Variants at 226 diabetes and glycemic trait loci were QTLs in beta and other cell types, including 40 that were statistically colocalized, and annotating target genes of colocalized QTLs revealed genes with putatively novel roles in disease. Our findings reveal diverse responses of pancreatic cell types to phenotype and genotype in physiology, and identify pathways, networks, and genes through which physiology impacts diabetes risk.

Delivery of US28 by incoming HCMV particles rapidly attenuates Akt activity to suppress HCMV lytic replication in monocytes.

Establishing a nonproductive, quiescent infection within monocytes is essential for the spread of human cytomegalovirus (HCMV). We investigated the mechanisms through which HCMV establishes a quiescent infection in monocytes. US28 is a virally encoded G protein-coupled receptor (GPCR) that is essential for silent infections within cells of the myeloid lineage. We found that preformed US28 was rapidly delivered to monocytes by HCMV viral particles, whereas the de novo synthesis of US28 was delayed for several days. A recombinant mutant virus lacking US28 (US28Δ) was unable to establish a quiescent infection, resulting in a fully productive lytic infection able to produce progeny virus. Infection with US28Δ HCMV resulted in the phosphorylation of the serine and threonine kinase Akt at Ser473 and Thr308, in contrast with the phosphorylation of Akt only at Ser473 after WT viral infection. Inhibiting the dual phosphorylation of Akt prevented the lytic replication of US28Δ, and ectopic expression of a constitutively phosphorylated Akt variant triggered lytic replication of wild-type HCMV. Mechanistically, we found that US28 was necessary and sufficient to attenuate epidermal growth factor receptor (EGFR) signaling induced during the entry of WT virus, which led to the site-specific phosphorylation of Akt at Ser473. Thus, particle-delivered US28 fine-tunes Akt activity by limiting HCMV-induced EGFR activation during viral entry, enabling quiescent infection in monocytes.

Lecanemab and Vascular-Amyloid Deposition in Brains of People With Down Syndrome.

Importance: Anti-ß-amyloid immunotherapy using lecanemab is becoming increasingly available to patients with Alzheimer disease (AD). Individuals with Down syndrome (DS) develop AD neuropathology by age 40 years, representing a significant cohort of genetically determined AD. Objective: To investigate the binding properties of lecanemab in the brains of people with DS, in anticipation of their inclusion in clinical trials or access to antiamyloid immunotherapies. Design, Setting, Participants: The study included cases of postmortem brain tissue analysis from 15 individuals with DS aged 43 to 68 years that were acquired from Alzheimer Disease research centers at the University of California, Irvine and the University of Kentucky from 2008 to 2021. Data were analyzed from August 2023 through May 2024. Exposure: The binding properties of lecanemab were assessed in brain tissue. Main Outcome: The primary outcome was the extent of lecanemab binding to amyloid plaques and brain blood vessels. Results: Tissue from 15 people (8 were female [53%]) with DS ranging in age from 43 to 68 (mean, 56.6) years were included in the study. Lecanemab-labeled amyloid plaques appeared in all 15 DS cases studied, indicating potential target engagement. However, extensive binding of lecanemab to brain blood vessels in DS was observed, raising significant safety concerns. These findings underscore the necessity for clinical trials of lecanemab in people with DS to evaluate both safety and efficacy, particularly in individuals older than 43 years. Conclusions and Relevance: These findings suggest significant binding of lecanemab to cerebral amyloid angiopathy in DS. Lecanemab should be rigorously tested in clinical trials for AD in the DS population to determine its safety and efficacy, especially in those older than 43 years.

Age and initial position affect movement biomechanics in sit to walk transitions: Whole body balance and trunk control.

Maintaining dynamic balance during transitional movements like sit-to-walk (STW) can be challenging for older adults. Age-related neuromuscular decline can alter movement in STW, such as rising with greater trunk flexion, narrowing the feet, or using arms to push off. Initial foot and arm position can affect subsequent movement biomechanics, with different ground reaction forces (GRFs) that stabilize and advance the body center of mass (COM). The purpose of this study was to quantify whole-body biomechanics and trunk control of STW transitions. Fifteen younger adults (18-35 years) and fifteen older adults (50-79 years) performed STW from four initial foot positions and two arm positions. Three-dimensional (3D) GRFs, 3D body COM displacement, and integrated electromyography values from the lumbar paraspinals and gluteus medius were evaluated. Younger adults generated greater mediolateral GRF ranges while rising, whereas older adults generated greater mediolateral GRF ranges when stepping forward suggesting different strategies to laterally control the body COM. Initial foot position affected the STW movement, with narrow foot positions having smaller body COM displacement than wide foot positions, associated with smaller medial GRFs to move the body COM toward the stance limb. Rising with arm support required less lumbar paraspinal excitation, which was further reduced when with a posteriorly offset foot. Gluteus medius activity was greater for older adults compared to younger adults in STW. Completing STW with arm support can reduce the muscle activity required to stabilize the torso when rising, which likely has implications for balance control and low back loading.

Changes in Atherosclerotic Cardiovascular Disease Risk Scores in a Predominantly Black Cohort with HIV and Associated Comorbidities: A Preliminary Study.

INTRODUCTION: People with HIV (PWH) have an increased risk of atherosclerotic cardiovascular disease (ASCVD) compared to non-PWH, but the reasons for this increased risk remain elusive. We investigated the change in ASCVD risk scores over 4 years to identify clinical factors associated with change in risk scores or high-risk scores. METHODS: We conducted a preliminary study using retrospective analysis of PWH, between 40 and 75 years old, seen at the Evelyn Jordan Center with at least two routine HIV visits. We collected clinical and demographic data and calculated the ASCVD risk scores using the Pooled Cohort Equation. Exploratory analyses examined change in risk score categories over time. Final adjusted analysis examined factors associated with change in continuous risk scores over time. RESULTS: Our sample included 187 PWH; 166 were black/African American and 79 were female. We found no significant change in ASCVD risk score over time. The risk score was significantly higher in PWH with hepatitis C (7.34%; 95% CI: 2.59, 12.09; p = 0.003) and trended higher in those with dual hepatitis B/C and hepatitis B compared to those without hepatitis (p = 0.07). CONCLUSION: We found that ASCVD risk did not change over a 4-year period among predominantly black young PWH, but infection with hepatitis C and dual hepatitis B/C were associated with higher ASCVD risk scores. Our findings illustrate the need for further longitudinal studies evaluating change in cardiovascular disease (CVD) risk and investigating viral hepatitis as an added potential contributor to increased CVD risk in high-risk, vulnerable populations.
