RESUMO
BACKGROUND AND OBJECTIVES: The Hazelwood Health Study was set up to study long-term health effects of a mine fire that blanketed residents of the Latrobe Valley with smoke for 45 days in 2014. The Respiratory Stream specifically assessed the impact of fine particulate matter <2.5 µm diameter (PM2.5) exposure from mine fire smoke on lung health. The multiple breath nitrogen washout (MBW) test assesses ventilation heterogeneity, which may detect sub-clinical airways dysfunction not identified using standard tests such as spirometry. This analysis assessed the association of PM2.5 exposure with measures of ventilation heterogeneity. METHODS: Exposed (Morwell) and unexposed (Sale) participants were recruited 3.5-4 years after the fire from those who had participated in an Adult Survey. MBW was performed to measure lung clearance index (LCI), functional residual capacity (FRC), acinar (Sacin) and conductive (Scond) ventilation heterogeneity. PM2.5 exposure was estimated with emission and chemical transport models. Multivariable linear regression models were fitted controlling for confounders. RESULTS: We recruited 519 participants. MBW tests were conducted on 504 participants with 479 acceptable test results (40% male; 313 exposed, 166 unexposed). Exposure to mine fire-related PM2.5 was associated with increasing Scond (ß = 1.57/kL, 95%CI: 0.20-2.95, p = 0.025), which was comparable to the estimated effect on Scond of 4.7 years of aging. No other MBW outcomes were statistically different. CONCLUSION: Increasing exposure to PM2.5 was associated with increased ventilation heterogeneity in the conductive region of the lungs 4 years after the event.
RESUMO
OBJECTIVE: To examine the uptake of postnatal contraception (PNC) and experiences of PNC care across a geographical region of England. DESIGN: Cross-sectional online survey. SETTING: The North East and North Cumbria Integrated Care System (ICS). POPULATION: Women who had completed a pregnancy in the previous 3 years. METHODS: The uptake of PNC by accessed method(s) and the availability of preferred method(s) is described, and adjusted odds ratios are reported for group differences in uptake by characteristics of interest. MAIN OUTCOME MEASURES: Uptake of medically prescribed/administered contraception and uptake of long-acting reversible contraception (LARC) during the postnatal period, and access to preferred PNC methods. RESULTS: Although almost half of respondents (47.1%; n = 1178) reinitiated some form of sexual activity during the postnatal period, only 38.7% (n = 969) of respondents accessed a medically prescribed/administered contraceptive method postnatally, and only 15.5% (n = 389) of respondents accessed a LARC. It is a matter of concern that 18.8% (n = 451) of respondents indicated that they were unable to access their preferred PNC. In multivariate analysis, younger age, lower household income, higher multiparity, operative delivery, unplanned pregnancy and not breastfeeding were significant predictors of higher PNC uptake. CONCLUSIONS: The uptake of PNC in this cohort was low, with almost a fifth of women unable to access their preferred method. However, there was some evidence that women belonging to groups perceived to be at risk of rapid repeat pregnancy were more likely to access reliable PNC methods.

Background: The care for patients with type 2 diabetes mellitus (T2DM) necessitates a multidisciplinary team approach to reduce cardiovascular (CV) risk but implementation of effective integrated strategies has been limited. Methods and Results: We report 2-year results from a patient-centered, team-based intervention called CINEMA at University Hospitals Cleveland Medical Center. Patients with T2DM or prediabetes at high-risk for CV events, including those with established atherosclerotic CVD, elevated coronary artery calcium score ≥100, chronic heart failure with reduced ejection fraction, chronic kidney disease (CKD) stages 2-4, and/or prevalent metabolic syndrome were included. From May 2020 through September 2022, 426 patients were enrolled in the CINEMA program. A total of 227 (54%) completed ≥1 follow-up visit after an initial baseline visit with median (IQR) follow-up time 4 [3], [4], [5], [6], [7] months with maximum follow-up time 19 months. Mean age was 60 years, 47 % were women, and 37 % were Black and 85% had prevalent T2DM, 48 % had established ASCVD, 29% had chronic HF, 27% had CKD and mean baseline 10-year ASCVD risk estimate was 25.1 %; baseline use of a SGLT2i or GLP-1RA was 21 % and 18 %, respectively. Patients had significant reductions from baseline in body weight (-5.5 lbs), body mass index (-0.9 kg/m2), systolic (-3.6 mmHg) and diastolic (-1.2 mmHg) blood pressure, Hb A1c (-0.5 %), total (-10.7 mg/dL) and low-density lipoprotein (-9.0 mg/dL) cholesterol, and triglycerides (-13.5 mg/dL) (p<0.05 for all). Absolute 10-year predicted ASCVD risk decreased by â¼2.4 % (p<0.001) with the intervention. In addition, rates of guideline-directed cardiometabolic medication prescriptions significantly increased during follow-up with the most substantive changes seen in rates of SGLT2i and GLP-1RA use which approximately tripled from baseline (21 % to 57 % for SGLT2i and 18 % to 65 % for GLP-1RA, p<0.001 for both). Conclusions: The CINEMA program, an integrated, patient-centered, team-based intervention for patients with T2DM or prediabetes at high risk for cardiovascular disease has continued to demonstrate effectiveness with significant improvements in ASCVD risk factors and improved use of evidence-based therapies. Successful implementation and dissemination of this care delivery paradigm remains a key priority.
RESUMO
Background: Severe hypercholesterolemia (SH), defined as a low-density lipoprotein cholesterol (LDL-C) level ≥ 190 mg/dl, is associated with an increased risk for premature atherosclerotic cardiovascular disease. Despite guideline recommendations, many patients with severe hypercholesterolemia remain untreated. We conducted an observational analysis of a large pool of SH patients, exploring demographic and social factors contributing to disparities in the prescription of statin and other lipid-lowering therapies. Methods: We included all adults (age 18 or older) in the University Hospitals Health Care System, with an LDL-C ≥ 190 mg/dl on a lipid profile drawn between January 2, 2014, and March 15, 2022. Variables were compared across relevant categories of age, gender, race and ethnicity, medical history, prescription medication status, insurance type, and provider referral type. We used the Fischer exact test and Pearson Chi-square (χ 2) for variable comparisons. Results: A total of 7,942 patients were included in the study. The median age was 57 [IQR 48-66] years with 64% female, and 17% Black patients. Only 58% of the total cohort was prescribed statin therapy. Higher age was independently associated with a higher likelihood of receiving a statin, with an odds ratio of 1.25 (95% CI [1.21 - 1.30] per 10 years, p<0.001). Additional factors that were associated with higher rates of statin prescription in patients with SH were Black race (OR 1.90, 95% CI [1.65 - 2.17], p<0.001), smoking (OR 2.42, 95% CI [2.17 -2.70], p<0.001), and presence of diabetes (OR 3.88, 95% CI [3.27 - 4.60], p<0.001). Similar trends were also seen with other lipid-lowering therapies such as ezetimibe and fibrates. Conclusions: In our Northeast Ohio healthcare system, less than two-thirds of patients with severe hypercholesterolemia are prescribed a statin. Statin prescription rates were highly dependent on age and the presence of additional ASCVD risk factors.
RESUMO
OBJECTIVE: To review evidence of existing and new pharmacological therapies for lowering lipoprotein(a) (Lp[a]) concentrations and their impact on clinically relevant outcomes. METHODS: We searched for literature pertaining to Lp(a) and pharmacological treatments in PubMed. We reviewed articles published between 1963 and 2020. RESULTS: We found that statins significantly increased Lp(a) concentrations. Therapies that demonstrated varying degrees of Lp(a) reduction included ezetimibe, niacin, proprotein convertase subtilisin/kexin type 9 inhibitors, lipoprotein apheresis, fibrates, aspirin, hormone replacement therapy, antisense oligonucleotide therapy, and small interfering RNA therapy. There was limited data from large observational studies and post hoc analyses showing the potential benefits of these therapies in improving cardiovascular outcomes. CONCLUSION: There are multiple lipid-lowering agents currently being used to treat hyperlipidemia that also have a Lp(a)-lowering effect. Two RNA therapies specifically targeted to lower Lp(a) are being investigated in phase 3 clinical trials and, thus far, have shown promising results. However, evidence is lacking to determine the clinical relevance of reducing Lp(a). At present, there is a need for large-scale, randomized, controlled trials to evaluate cardiovascular outcomes associated with lowering Lp(a).

BACKGROUND: Heroin use may work synergistically with human immunodeficiency virus (HIV) infection to cause greater immune dysregulation than either factor alone. Unraveling how this affects end-organ disease is key as it may play a role in the excess mortality seen in people with HIV (PWH) who use heroin despite access to care and antiretroviral therapy. METHODS: This is a prospectively enrolled, cross-sectional study of adults with and without HIV who use and do not use heroin using (18)F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) to compare tissue-specific inflammation including aortic (target-to-background ratio [TBR]), splenic, and bone marrow (standardized uptake value [SUV]). RESULTS: A total of 120 participants were enrolled. The unadjusted mean difference in aortic TBR was 0.43 between HIV-positive [HIV+] heroin+ and HIV+ heroin-negative [heroin-] (P = .02); however, among HIV-, aortic TBR was similar regardless of heroin-use status. Further, HIV-by-heroin-use status interaction was significant (P = .02), indicating that the relationship between heroin use and higher aortic TBR depended on HIV status. On the other hand, both HIV (1.54 vs 1.68; P = .04, unadjusted estimated means for HIV+ vs HIV-) and heroin use were associated with lower bone marrow SUV, although the effect of heroin depended on sex (heroin-use-by-sex interaction, P = .03). HIV-by-heroin-use interaction was not significant for splenic or bone marrow SUV. CONCLUSIONS: Aortic inflammation was greatest in PWH who use heroin, but paradoxically, bone marrow activity was the least in this group, suggesting complex and possibly divergent pathophysiology within these different end organs.

Cardiac sarcoidosis is a challenging clinical entity in terms of diagnosis and management. Cardiac involvement is the most common cause of death in patients with sarcoidosis. Recently, there have been new advancements in the imaging modalities that aid in the diagnosis of this condition, including cardiac MRI and PET scan. These tools can help identify and determine the extent of the progression of sarcoidosis, which can have diagnostic and therapeutic implications. In this report, we present the case of a 74-year-old man with no history of sarcoidosis who presented with sustained ventricular tachycardia (VT) and was subsequently found to have findings consistent with burnt-out sarcoidosis on imaging. This case highlights the differences in the management of various stages of cardiac sarcoid involvement to reduce adverse outcomes.
RESUMO
Background: Prior studies have suggested significant underutilization of statins in women and worse cardiovascular outcomes. Data examining the impact of real-world coronary artery calcium (CAC) scoring to improve utilization of preventive therapies and outcomes is limited. Methods: In a prospective registry study of low cost or no-cost CAC scoring between 2014 and 19 (CLARIFY Study, Clinicaltrials.gov NCT04075162), we sought to study the association of CAC scoring on statin utilization, blood lipids (LDL, total cholesterol, triglycerides), downstream ischemic testing (coronary angiography and stress testing), coronary revascularization and outcomes (MI, stroke, death) in women compared with men. Eligibility for statin initiation was defined as atherosclerotic cardiovascular disease pooled cohort equation (ASCVD-PCE) ≥ 7.5% and CAC≥100/≥75th percentile. Results: A total of 52,151 patients (26,336 women and 25,815 men) were enrolled. Women were more likely to have CAC 0 (51% vs 30%, P<0.001). Among patients not eligible for statin by PCE, CAC reclassified statin eligibility in a smaller proportion of women than men (25.4% vs 30%, P<0.001), while among patients eligible for statin by PCE, CAC was more likely to downgrade risk/statin eligibility in women than men (30.1% vs 48.4%, P<0.001). After CAC scoring, statin initiation was similar in women and men, but high-intensity statin use was lower in women (CAC-adjusted HR 0.76 [0.70-0.83], P<0.001). Women had similar reduction in LDL cholesterol levels compared with men. There was no difference between men and women with respect to CAC-stratified major adverse cardiovascular events. Conclusion: CAC scoring primarily served to downgrade statin eligibility in women compared with men. Women had similar CAC risk-guided reductions in LDL cholesterol compared with men.
RESUMO
Background The care for patients with type 2 diabetes necessitates a multidisciplinary team approach to reduce cardiovascular risk, but implementation of effective integrated strategies has been limited. Methods and Results We conceptualized and initiated a patient-centered, team-based intervention called Center for Integrated and Novel Approaches in Vascular-Metabolic Disease (CINEMA) at University Hospitals Cleveland Medical Center. Patients with type 2 diabetes at high risk for cardiovascular events, including those with established atherosclerotic cardiovascular disease, elevated coronary artery calcium score >100, chronic heart failure with reduced ejection fraction, and/or chronic kidney disease stages 2 to 4 were included. Herein, we present the year 1 results for the program. From May 2020 through August 2021, there were 417 referrals. Among 206 eligible patients, 113 (55%) completed a baseline and ≥1 follow-up visit through December 2021, with mean (SD) time of 105 (34) days between baseline and first follow-up visits. Mean age was 59 years, with 49% women and 37% Black patients. Patients had significant reductions from baseline in glycosylated hemoglobin (-10.8%), total cholesterol (-7.9%), low-density lipoprotein cholesterol (-13.5%), systolic blood pressure (-4.0%), and body mass index (-2.7%) (P≤0.001 for all). In addition, among the 129 (63%) eligible patients not on sodium-glucose cotransporter 2 inhibitor or glucagon-like peptide-1 receptor agonist at baseline, 81% were prescribed evidence-based therapy with sodium-glucose cotransporter 2 inhibitor (n=66 [51%]) and/or glucagon-like peptide-1 receptor agonist (n=67 [52%]) to reduce the risk of cardiovascular disease in the initial 3-month follow-up period. Conclusions A team-based, patient-centered approach to high-risk disease management appears to be a promising paradigm for care delivery associated with greater use of evidence-based therapies and improved control of multiple cardiovascular risk factors.

There is a poor understanding of why some patients with asthma experience recurrent exacerbations despite high levels of treatment. We compared measurements of peripheral ventilation heterogeneity and respiratory system mechanics in participants with asthma who were differentiated according to exacerbation history, to ascertain whether peripheral airway dysfunction was related to exacerbations. Three asthmatic groups: "stable" (no exacerbations for >12 mo, n = 18), "exacerbation-prone" (≥1 exacerbation requiring systemic corticosteroids within the last 12 mo, but stable for ≥1-mo, n = 9), and "treated-exacerbation" (exacerbation requiring systemic corticosteroids within the last 1 mo, n = 12) were studied. All participants were current nonsmokers with <10 pack yr smoking history. Spirometry, static lung volumes, ventilation heterogeneity from multibreath nitrogen washout (MBNW), and respiratory system mechanics from oscillometry were measured. The exacerbation-prone group compared with the stable group had slightly worse spirometry [forced expired volume in 1 s or FEV1 z-score -3.58(1.13) vs. -2.32(1.06), P = 0.03]; however, acinar ventilation heterogeneity [Sacin z-score 7.43(8.59) vs. 3.63(3.88), P = 0.006] and respiratory system reactance [Xrs cmH2O·s·L-1 -2.74(3.82) vs. -1.32(1.94), P = 0.01] were much worse in this group. The treated-exacerbation group had worse spirometry but similar small airway function, compared with the stable group. Patients with asthma who exacerbate have worse small airway function as evidenced by increases in Sacin measured by MBNW and ΔXrs from oscillometry, both markers of small airway dysfunction, compared with those that do not.NEW & NOTEWORTHY This study assessed the relationship between peripheral airway function, measured by multiple breath nitrogen washout and oscillometry impedance, and exacerbation history. We found that those with a history of exacerbation in the last year had worse peripheral airway function, whereas those recently treated for an asthma exacerbation had peripheral airway function that was comparable to the stable group. These findings implicate active peripheral airway dysfunction in the pathophysiology of an asthma exacerbation.

Recently, coronavirus disease 2019 (COVID-19, caused by SARS-CoV-2) has posed a challenge for clinicians, particularly extrapulmonary manifestations. These manifestations are often rare and difficult to recognize as research is still underway for the myriad presentations of the disease. A 19-year-old man presented with viral upper respiratory infection (URI) symptoms and received a positive result for SARS-CoV-2 real-time reverse transcription polymerase chain testing. A few days later, he developed abdominal pain and presented to the Emergency Department (ED). He was found to have bradycardia, right lower quadrant pain, fevers, and elevated inflammatory markers. An abdominal computed tomography scan showed appendicitis and an electrocardiogram showed third-degree heart block. He underwent successful implantation of a dual-chamber permanent pacemaker and was scheduled for elective appendectomy. This case illustrates a state of system-wide inflammation that has been described mainly in pediatric patients with SARS-CoV-2 known as multisystem inflammatory syndrome in children (MIS-C). Recognition of this syndrome is crucial as it has potential diagnostic and therapeutic implications that can improve outcomes.
RESUMO
BACKGROUND: The Voluntary Community and Social Enterprise sector has a crucial role in supporting the health and wellbeing of people who are marginalised or who have multiple complex needs. We aimed to understand perceptions of those working in the sector and examine the short-term, medium-term, and long-term effects of COVID-19 on Voluntary Community and Social Enterprise organisations in northern England as they respond to the needs of marginalised communities. This research formed one component of a regional multiagency Health Inequalities Impact Assessment. METHODS: We conducted qualitative focus groups with staff and volunteers from five organisations between March and July, 2021, via a video conferencing platform. Eight of nine focus groups were audio-recorded and transcribed verbatim. One focus group was not recorded due to concerns raised over anonymity and safeguarding, but non-ascribed fieldnotes were taken. Focus group transcripts were analysed using framework analysis. FINDINGS: One organisation supported children and young people; two organisations supported vulnerable women, young people, and families; one organisation supported refugees and asylum seekers, and one organisation supported disadvantaged individuals to improve their mental and physical health and wellbeing. Three central themes were identified: the exacerbation of pre-existing inequalities, adversity, and challenges for vulnerable and marginalised populations; the cost of being flexible, innovative, and agile for Voluntary Community and Social Enterprise staff and volunteers; and the voluntary sector as a lifeline (organisational pride and resilience). INTERPRETATION: The considerable expertise, capacity, and resilience of Voluntary Community and Social Enterprise organisations and the crucial role they have in supporting marginalised communities has been clearly shown in their response to the COVID-19 pandemic. The Voluntary Community and Social Enterprise sector therefore has an essential role in the post-COVID levelling-up agenda. The implications of these findings for service provision are that the Voluntary Community and Social Enterprise sector must be recognised as an integral partner within any effectively functioning local health system and, as such, adequately resourced to safeguard sustainability and to ensure that attempts to involve the sector in addressing the social determinants of health are not jeopardised.

BACKGROUND: Low-density lipoprotein cholesterol (LDL-C) is estimated from total cholesterol, high-density lipoprotein cholesterol and triglycerides using predefined equations which assume fixed or varying relationships between these parameters and may underestimate or overestimate LDL-C. Data on the performance of these equations in persons with HIV are limited. We sought to investigate the utility of the 3 most widely used methods (Friedewald, Hopkins, and the recently proposed NIH equation) to predict LDL-C in persons with HIV. METHODS: We identified 7397 direct LDL-C (5219 HIV, 2127 uninfected controls, 51 seroconvertors) measurements in the Women's Interagency HIV Study, and used the 3 equations (Friedewald, Hopkins, and NIH) to calculate LDL-C. We compared the performance of the 3 equations using root mean square error and coefficient of determination (R2). RESULTS: Overall, the Friedewald equation had the best performance characteristics, outperforming Hopkins and NIH methods with lower root mean square error and higher R2 at lower triglyceride levels. However, this association did not hold true at higher triglyceride levels (quartiles 3 and 4), whereas the Hopkins equation had better performance characteristics in quartile 3, none of the 3 equations were optimal in quartile 4. After adjusting for fasting status and triglycerides levels, HIV+ had larger mean difference compared with directly measured LDL using all 3 methods. CONCLUSIONS: All 3 methods have lower accuracy in HIV+ vs HIV- women, even after adjusting for triglyceride levels and fasting status. Further research should focus on identifying methods to estimate LDL-C in HIV.

OBJECTIVE: To determine the association of smoking and HIV status with tissue-specific inflammation measured by flurodeoxyglucose positron emission tomography (PET). DESIGN: A cross-sectional study. METHODS: We prospectively enrolled 55 HIV study participants on stable antiretroviral therapy and 19 age-matched HIV-uninfected controls without known cardiovascular disease. We measured aortic target-to-background ratio (TBR) and spleen standardized uptake values (SUV) 3-h post-FDG, and used regression models to examine the independent association of HIV and smoking status with PET variables. RESULTS: Overall, median (interquartile range) age was 50 (42-55) years; 81% were men and 54% were current smokers (median 0.5 packs/day, 25 pack-years]. Median CD4 of HIV study participants was 690âcells/ml and 88% had HIV-1 RNA less than 20âc/ml; 43% were on a protease inhibitor. In fully adjusted models, HIV was associated with 0.16 (95% confidence interval 0.04-0.27; Pâ=â0.009) higher aortic TBR, whereas current smoking was marginally associated with a lower TBR [-0.11 (95% confidence interval -0.23 to 0.01); Pâ=â0.07]. Spleen SUVmean was not associated with HIV or smoking, and there was no evidence for an HIVsmoking interaction for aortic or spleen models (all Pâ>â0.1). Spleen SUVmean was positively associated with biomarkers of inflammation and coronary artery calcium, but adjustment for traditional cardiovascular disease risk factors attenuated these relationships. CONCLUSION: The FDG-PET study of HIV study participants suggests that HIV is associated with increased aortic inflammation independent of traditional risk factors, but smoking is not. Future studies should continue to explore the mechanistic roles of smoking and inflammation at various stages of clinical and subclinical atherosclerotic vascular disease in HIV.

AIMS: To examine the relationship between a TV-led breast cancer mass-media campaign in the North East of England (conducted in two waves: Jul/2015 and Nov/2015), awareness of the link between alcohol and cancer, intention to reduce alcohol consumption and support for alcohol related policies. METHODS: Three cross-sectional surveys were conducted; one over the 2 weeks pre-campaign (n = 572); one immediately following campaign wave 1 (n = 576); and another immediately following campaign wave 2 (n = 552). Survey questions assessed; campaign exposure; awareness of the links between alcohol and related cancers; intention to change alcohol consumption; and support for alcohol related policies. RESULTS: The proportion of respondents indicating awareness of alcohol as a cancer risk factor was larger post-campaign compared to pre-campaign. The largest increase was seen for breast cancer with 45% aware of the links post-campaign wave 2 compared to 33% pre-campaign. The proportion of respondents indicating 'strong support' of the seven alcohol related policies significantly increased between surveys. The proportion of respondents both aware of alcohol as a cancer risk factor and supportive of the seven alcohol related policies significantly increased between surveys. There was no significant change in self-reported intention to reduce alcohol consumption amongst increasing/higher risk drinkers. CONCLUSION: These findings indicate that a mass-media campaign raising awareness of the links between alcohol and breast cancer is associated with increased awareness and alcohol related policy support at a population level. However, there was no association found with a change in short-term drinking intentions. SHORT SUMMARY: A mass-media campaign raising awareness of the links between alcohol and breast cancer is associated with increased awareness and alcohol policy support at a population level but does not appear to be associated with a change in short term drinking intentions.

PURPOSE OF REVIEW: This article describes the potential contribution of immune activation in the pathogenesis of HIV-associated cardiovascular disease (CVD) - a leading cause of morbidity and mortality among HIV-positive persons with access to antiretroviral therapy (ART). RECENT FINDINGS: We review recent literature that suggests abnormalities in both adaptive and innate immunity contributes to CVD risk among persons with HIV infection. In particular, potentially atherogenic T-cell mechanisms include persistent high-level T-cell activation (and associated proinflammatory mechanisms), as well as the presence of copathogens (e.g., cytomegalovirus) providing an ongoing stimulus for cytotoxic T-cell responses. More recent data have then emphasized the potential impact of monocyte-/macrophage-mediated inflammation and injury within atherosclerotic lesions. The abnormality driving innate immune activation many not fully reverse with antiretroviral therapy, highlighting the need for interventions that target inflammation as a CVD prevention strategy. SUMMARY: Premature CVD among persons with HIV infection is due, in part, to persistent abnormalities in immune activation and systemic inflammation despite viral suppression. Prevention strategies for persons with HIV infection include those that target traditional CVD risk factors, as well as newer candidate treatments with potential immunomodulatory benefits.
