Testosterone and the risk of incident atrial fibrillation in older men: further analysis of the ASPREE study

A cardiovascular safety trial of testosterone in men with cardiovascular risk factors or disease found no difference in rates of major adverse cardiovascular events (MACE) or death but noted more atrial fibrillation (AF) events in testosterone-treated men. We investigated the relationship between endogenous testosterone concentrations with risk of developing AF in healthy older men. Post-hoc analysis of 4570 male participants in the ASPirin in Reducing Events in the Elderly (ASPREE) study. Men were aged ≥ 70 years, had no history of cardiovascular disease (including AF), thyroid disease, prostate cancer, dementia, or life-threatening illnesses. Risk of AF was modelled using Cox proportional hazards regression. Median (IQR) age was 73.7 (71.6-77.1) years and median (IQR) follow-up 4.4 (3.3-5.5) years, during which 286 men developed AF (15.3 per 1000 participant-years). Baseline testosterone was higher in men who developed incident AF compared men who did not [17.0 (12.4-21.2) vs 15.7 (12.2-20.0) nmol/L]. There was a non-linear association of baseline testosterone with incident AF. The risk for AF was higher in men with testosterone in quintiles (Q) 4&5 (Q4:Q3, HR=1.91; 95%CI=1.29-2.83 and Q5:Q3HR=1.98; 95%CI=1.33-2.94). Results were similar after excluding men who experienced MACE or heart failure during follow-up. Circulating testosterone concentrations within the high-normal range are independently associated with an increased risk of incident AF amongst healthy older men. This suggests that AF may be an adverse consequence of high-normal total testosterone concentrations.

Treatment for intracerebral hemorrhage: Dawn of a new era.

Intracerebral hemorrhage (ICH) is a devastating disease, causing high rates of death, disability, and suffering across the world. For decades, its treatment has been shrouded by the lack of reliable evidence, and consequently, the presumption that an effective treatment is unlikely to be found. Neutral results arising from several major randomized controlled trials had established a negative spirit within and outside the stroke community. Frustration among researchers and a sense of nihilism in clinicians has created the general perception that patients presenting with ICH have a poor prognosis irrespective of them receiving any form of active management. All this changed in 2023 with the positive results on the primary outcome in randomized controlled trials showing treatment benefits for a hyperacute care bundle approach (INTERACT3), early minimal invasive hematoma evacuation (ENRICH), and use of factor Xa-inhibitor anticoagulation reversal with andexanet alfa (ANNEXa-I). These advances have now been extended in 2024 by confirmation that intensive blood pressure lowering initiated within the first few hours of the onset of symptoms can substantially improve outcome in ICH (INTERACT4) and that decompressive hemicraniectomy is a viable treatment strategy in patients with large deep ICH (SWITCH). This evidence will spearhead a change in the perception of ICH, to revolutionize the care of these patients to ultimately improve their outcomes. We review these and other recent developments in the hyperacute management of ICH. We summarize the results of randomized controlled trials and discuss related original research papers published in this issue of the International Journal of Stroke. These exciting advances demonstrate how we are now at the dawn of a new, exciting, and brighter era of ICH management.

Deciphering Trends in Cancer Mortality: A Comprehensive Analysis of Brazilian Data From 1979 to 2021 With Emphasis on Breast and Prostate Cancers.

This study examined cancer mortality trends in Brazil from 1979 to 2021, emphasizing breast and prostate cancers. Utilizing data from the Brazilian Mortality Information System and the Brazilian Institute of Geography and Statistics, it analyzed cancer deaths nationally and regionally, highlighting gender-specific and regional disparities. The research finds that cancer death rates have been growing at an average of 12% per year, contrasting with the population growth rate of 2.2%. This trend is more pronounced in the southern and southeastern regions of Brazil. A comparison of cancer mortality rates between Brazil, the USA, and China reveals that while the Brazilian and Chinese rates exhibit slower growth, the US rate shows a continuous decline since the 1990s. The study adopts a novel approach by focusing on growth rates and employing polynomial interpolation, revealing a deceleration in cancer death growth over the last 15 years across all malignant neoplasms. The study also contextualizes these findings within Brazil's cancer control policies, tracing the evolution of preventive measures and treatment advancements. It highlights the significant role of the National Cancer Institute and the Unified Health System in implementing effective strategies. The decreasing trend in cancer mortality rates in Brazil, despite population growth, illustrates the effectiveness of comprehensive cancer control and prevention measures, underlining their importance in public health policy.

Mathematical model for IL-2-based cancer immunotherapy

A basic mathematical model for IL-2-based cancer immunotherapy is proposed and studied. Our analysis shows that the outcome of therapy is mainly determined by three parameters, the relative death rate of CD4+ T cells, the relative death rate of CD8+ T cells, and the dose of IL-2 treatment. Minimal equilibrium tumor size can be reached with a large dose of IL-2 in the case that CD4+ T cells die out. However, in cases where CD4+ and CD8+ T cells persist, the final tumor size is independent of the IL-2 dose and is given by the relative death rate of CD4+ T cells. Two groups of in silico clinical trials show some short-term behaviors of IL-2 treatment. IL-2 administration can slow the proliferation of CD4+ T cells, while high doses for a short period of time over several days transiently increase the population of CD8+ T cells during treatment before it recedes to its equilibrium. IL-2 administration for a short period of time over many days suppresses the tumor population for a longer time before approaching its steady-state levels. This implies that intermittent administration of IL-2 may be a good strategy for controlling tumor size.

Epidemiology and demographic patterns of cardiovascular diseases and neoplasms deaths in Western Europe: a 1990–2019 analysis

ObjectivesCardiovascular diseases (CVDs) and neoplasms have been considered as public health concerns worldwide. This study aimed to estimate the epidemiological patterns of death burden on CVDs and neoplasms and its attributable risk factors in Western Europe from 1990 to 2019 to discuss the potential causes of the disparities. Study design and methodsWe collected data on CVDs and neoplasm deaths in 24 Western European countries from the Global Burden of Disease Study. We analyzed patterns by age, sex, country, and associated risk factors. The results include percentages of total deaths, age-standardized death rates per 100,000 population, and uncertainty intervals (UIs). Time trends were assessed using annual percent change. ResultsIn 2019, CVDs and neoplasms accounted for 33.54% and 30.15% of Western Europe's total deaths, with age-standardized death rates of 128.05 and 137.51 per 100,000. Over 1990–2019, CVD rates decreased by 54.97%, and neoplasm rates decreased by 19.54%. Top CVD subtypes were ischemic heart disease and stroke; top cancers for neoplasms were lung and colorectal. Highest CVD death burdens were in Finland, Greece, Austria; neoplasm burdens in Monaco, San Marino, Andorra. The major risk factors were metabolic (CVDs) and behavioral (neoplasms). Gender differences revealed higher CVD death burden in males, while neoplasm burden varied by risk factors and age groups. ConclusionIn 2019, CVDs and neoplasms posed significant health risks in Western Europe, with variations in death burdens and risk factors across genders, age groups, and countries. Future interventions should target vulnerable groups to lessen the impact of CVDs and neoplasms in the region.

Alert System for Emergency State of Vehicle Users

Abstract: One of the main reasons for road collisions is over-speeding. The sharp rise in traffic accidents is currently one of the main causes of human deaths. The worth of human life is above all other factors, and providing immediate assistance is more important than lending a hand help. If emergency personnel had been able to get accident reports and get there in time, more lives might have been saved. When it comes to saving lives, the time it takes from the moment of the accident until the ambulance arrives at the scene is critical. We can reduce the time between an accident occurring and a medical ambulance being dispatched to the scene by lowering death rates. Today, GPS is a crucial part of a vehicle's system. The accelerometer senses a quick shift in the axles of the vehicle. It will be evaluated by Arduino. The warning message and its position are sent to the police control room or a rescue team by the Arduino using the GSM module. Therefore, once they get the information, the authorities can use the GPS module to trace the location automatically. The appropriate action will be carried out after the location has been verified

Suicide Deaths Involving Opioid Poisoning in the United States by Sex, 1999 - 2021.

Suicide remains a leading cause of death in the United States, and recent data suggests that suicide deaths involving opioids are increasing. Given unprecedented increases in drug poisoning deaths, suicidality, and suicide deaths in recent years, an updated examination of the trends in suicide deaths involving opioids is warranted. In this descriptive epidemiologic analysis, we leverage final and provisional mortality data from CDC WONDER to examine trends in suicide deaths involving opioid poisoning from 1999 - 2021 by biological sex. Results reveal complex changes over time: the number and age-adjusted rate of suicide deaths involving opioid poisoning among male and female residents tended to track together, and both increased through 2010, but then diverged with the number and rate of suicide deaths involving opioid poisoning among female residents outpacing that of male residents. However, the number and rate of suicide deaths involving opioid poisoning among male residents then began to stabilize, while that of female residents declined, closing the sex-based gap. Across all years of data, the proportion of suicide deaths that involved opioid poisoning was consistently higher among female decedents (5.8% - 11.0%) compared to male decedents (1.4% - 2.8%). Findings have implications for improved suicide prevention and harm reduction efforts.

Revisiting Race and the Benefit of RAS Blockade in Heart Failure: A Meta-Analysis of Randomized Clinical Trials.

Concerns have arisen that renin-angiotensin system (RAS) blockers are less effective in Black patients than non-Black patients with heart failure and reduced ejection fraction (HFrEF). To determine whether the effects of RAS blockers on cardiovascular outcomes differ between Black patients and non-Black patients with HFrEF. MEDLINE and Embase databases through December 31, 2023. Randomized trials investigating the effect of RAS blockers on cardiovascular outcomes in adults with HFrEF that enrolled Black and non-Black patients. Individual-participant data were extracted following Preferred Reporting Items for Systematic Reviews and Meta-analyses Independent Personal Data (PRISMA-IPD) reporting guidelines. Effects were estimated using a mixed-effects model using a 1-stage approach. The primary outcome was first hospitalization for HF or cardiovascular death. The primary analysis, based on the 3 placebo-controlled RAS inhibitor monotherapy trials, included 8825 patients (9.9% Black). Rates of death and hospitalization for HF were substantially higher in Black than non-Black patients. The hazard ratio (HR) for RAS blockade vs placebo for the primary composite was 0.84 (95% CI, 0.69-1.03) in Black patients and 0.73 (95% CI, 0.67-0.79) in non-Black patients (P for interaction = .14). The HR for first HF hospitalization was 0.89 (95% CI, 0.70-1.13) in Black patients and 0.62 (95% CI, 0.56-0.69) in non-Black patients (P for interaction = .006). Conversely, the corresponding HRs for cardiovascular death were 0.83 (95% CI, 0.65-1.07) and 0.84 (95% CI, 0.77-0.93), respectively (P for interaction = .99). For total hospitalizations for HF and cardiovascular deaths, the corresponding rate ratios were 0.82 (95% CI, 0.66-1.02) and 0.72 (95% CI, 0.66-0.80), respectively (P for interaction = .27). The supportive analyses including the 2 trials adding an angiotensin receptor blocker to background angiotensin-converting enzyme inhibitor treatment (n = 16 383) gave consistent findings. The mortality benefit from RAS blockade was similar in Black and non-Black patients. Despite the smaller relative risk reduction in hospitalization for HF with RAS blockade in Black patients, the absolute benefit in Black patients was comparable with non-Black patients because of the greater incidence of this outcome in Black patients.

Impact of malnutrition in patients with severe heart failure.

The role of malnutrition among patients with severe heart failure (HF) is not well established. We evaluated the incidence, predictors, and prognostic impact of malnutrition in patients with severe HF. Nutritional status was measured using the geriatric nutritional risk index (GNRI), based on body weight, height and serum albumin concentration, with malnutrition defined as GNRI ≤98. It was assessed in consecutive patients with severe HF, defined by at least one high-risk 'I NEED HELP' marker, enrolled at four Italian centres between January 2020 and November 2021. The primary endpoint was all-cause mortality. A total of 510 patients with data regarding nutritional status were included in the study (mean age 74 ± 12 years, 66.5% male). Among them, 179 (35.1%) had GNRI ≤98 (malnutrition). At multivariable logistic regression, lower body mass index (BMI) and higher levels of natriuretic peptides (B-type natriuretic peptide [BNP] > median value [685 pg/ml] or N-terminal proBNP > median value [5775 pg/ml]) were independently associated with a higher likelihood of malnutrition. Estimated rates of all-cause death at 1 year were 22.4% and 41.1% in patients without and with malnutrition, respectively (log-rank p < 0.001). The impact of malnutrition on all-cause mortality was confirmed after multivariable adjustment for relevant covariates (adjusted hazard ratio 2.03, 95% confidence interval 1.43-2.89, p < 0.001). In a contemporary, real-world, multicentre cohort of patients with severe HF, malnutrition (defined as GNRI ≤98) was common and independently associated with an increased risk of mortality. Lower BMI and higher natriuretic peptides were identified as predictors of malnutrition in these patients.

Global, regional, and national burden of trachea, bronchus, and lung cancer among women of reproductive age, 1990–2019

BackgroundTrachea, bronchus, and lung (TBL) cancer has demonstrated a discernible feminization and a tendency towards younger onset in recent decades. Therefore, our objective is to examine the most recent patterns in the worldwide prevalence of TBL among women of reproductive age on a global, regional, and national scale. MethodsTo assess the prevalence trends of TBL in women of reproductive age, we calculated the estimated annual percentage change (EAPC), age-standardized incidence rate (ASIR), age-standardized death rate (ASDR), and disability-adjusted life years (DALYs) for 204 countries and territories from 1990 to 2019. These calculations were based on the Global Burden of Disease (GBD) 2019 database. ResultsFrom 1990 to 2019, there was a global increase in the absolute number of incidence cases, deaths, and DALYs of TBL in women of reproductive age. However, the ASIR, ASDR, and age-standardized DALY rates were decreasing over this period, with EAPC of -0.77 (95 % confidence interval [CI]: -1.03 to -0.51), -1.08 (95 % CI: -1.34 to -0.82), and -1.10 (95 % CI: -1.36 to -0.84), respectively. This trend was observed even in regions with higher Socio-Demographic Index (SDI). East Asia consistently had the highest ASIR, ASDR, and age-standardized DALY rate, but there was a decreasing trend. Conversely, Eastern Sub-Saharan Africa displayed an increasing burden pattern. When examining countries individually, Monaco, Greenland, and Palau had the highest ASIR. Moreover, in most countries, the ASIR for TBL increased with age, particularly among women aged 35–49 years. ConclusionsDespite a global decline in ASIR, ASDR, and age-standardized DALY rates for TBL in women of reproductive age over the past three decades, there is still a troubling increase observed in low- and low-middle SDI regions. It is crucial to implement effective preventive and curative measures in these regions in order to address this concerning trend.

Evaluation of the frequency and risk factors of spontaneous intramuscular hemorrhage associated with dermatomyositis.

Dermatomyositis (DM) is an idiopathic inflammatory myositis (IIM) characterized by skin manifestations and muscle involvement. Spontaneous intramuscular hemorrhage (SIH) is a fatal complication that is very rare in the course of DM, but not well known to rheumatologists. Our aim was to determine the frequency and possible risk factors of DM-related SIH. A retrospective analysis was conducted on a cohort of DM patients who were observed in the rheumatology department of the university hospital between 1998 and January 2024. The clinical, laboratory, radiological data of the patients and the treatments they received during the follow-up were analyzed. To determine possible risk factors for the development of SIH in the course of DM, our patients with DM were analyzed together with other rare SIH cases in the literature. The study included 42 of our DM patients. 32 of the patients (76.2%) were female. The median age of the patients was 53 (24-82) years, the median age of DM diagnosis of the patients was 47 (18-75) years, and the median duration of DM of the patients was 36 (2-276) months. 7.1% of patients had dysphagia, and 16.7% had intertitial lung disease (ILD). 5 (11.9%) patients were diagnosed with malignancy. The incidence rate of SIH development in our DM cohort was 0.238/100 patient years (95% CI 0.006-1.256). We tried to identify independent risk factors for SIH development by comparing our 41 DM patients without SIH with the data of patients with 23 DM-related SIH collected from the literature by adding our 1 patient (24 pts). Male sex (OR 4.97, 95% CI 1.66-14.92, p = 0.003), ILD presence (OR 9.71, 95% CI 2.99-31.47, p < 0.001), anti-MDA5 positivity (OR 16.0, 95% CI 1.60-159.3, p = 0.006), anti-Ro52 positivity (OR 11.6, 95% CI 2.93-46.34, p < 0.001), heparin use (OR 4.42, 95% CI 2.68-7.24, p < 0.001), intravenous immunoglobulin (IVIG) use (OR 11.7, 95% CI 2.26-60.54, p < 0.001), and steroid dose (OR 1.03, 95% CI 1.00-1.05, p = 0.005) were identified as risk factors for the development of SIH in the univariate analysis. The death rate due to hemorrhage was 50%. No single risk factor was found to be associated with death. As a result, SIH may occasionally arise in patients with DM. Rheumatologists should be aware that patients with dysphagia and/or ILD, who are on heparin, getting high doses of steroids, and test positive for anti-MDA5 and/or anti-Ro52 antibodies may develop SIH in the early stages of DM.

Inequities in naloxone administration among fatal overdose decedents by race and ethnicity in Pennsylvania, 2019-21.

The aim of this study was to characterize the circumstances of drug overdose deaths and determine whether naloxone administration differed by overdose decedent race and ethnicity. Analysis of data on unintentional and undetermined intent drug overdose deaths in Pennsylvania (2019-21) was collected from death certificates and the State Unintentional Drug Overdose Reporting System. Multivariable logistic regression models were adjusted for overdose death circumstances and the odds of naloxone administration were estimated by race/ethnicity and year. The analytical sample included 3386 fatal overdose decedents in 2019, 3864 in 2020 and 3816 in 2021. Evidence of naloxone administration (yes/no) was defined using scene evidence and toxicology reports from coroner and medical examiner records, while race/ethnicity (Hispanic, non-Hispanic Black, non-Hispanic White) was based on the death certificate. In the analytic sample, overdose death rates were the highest among Black people and increased over time (rate per 10 000 population, 2019: 4.3; 2020: 6.1; 2021: 6.5); rates were lowest among White people and remained constant over time (rate per 10 000 population, 2019: 2.6; 2020: 2.7; 2021: 2.6). Throughout all years, Black decedents had approximately 40-50% lower odds of naloxone administration compared with White decedents as referent [2019: odds ratio (OR) = 0.7, 95% confidence interval (CI) = 0.5-0.9; 2020: OR = 0.5, 95% CI = 0.4-0.7; 2021: OR = 0.6, 95% CI = 0.5-0.8], while Hispanic decedents had similar odds of naloxone administration to that of White decedents. After controlling for overdose circumstances in drug overdose deaths in Pennsylvania, USA, from 2019 to 2021, Black people had lower odds of naloxone administration compared with White people, while there were no differences between Hispanic and White people.

Coronary Angiography in Patients With Left Ventricular Hypertrabeculation/Noncompaction.

Left ventricular hypertrabeculation/noncompaction (LVHT) is a cardiac abnormality of unknown pathogenesis, frequently associated with neuromuscular disorders. The relevance of coronary artery disease (CAD) in LVHT is largely unknown. This study aimed to assess the role of CAD as a prognostic marker in LVHT. Data from patients with LVHT were collected from an echocardiographic laboratory. The hospital information system was retrospectively screened for coronary angiography. The association of CAD with clinical, echocardiographic, and neurologic baseline parameters was assessed. End points were all-cause death and heart transplantation. A total of 154 patients (mean [SD] age, 57 [13.7] years; 31% female) who had undergone coronary angiography between 1995 and 2020 were included in the study. Coronary angiography disclosed CAD in 53 of 154 patients. Patients with CAD were older (mean [SD] age of, 64.2 [12.9] years vs 52.7 [12.4] years; P < .001); more frequently had angina pectoris (P = .05), diabetes (P = .002), and hypertension (P = .03); and more frequently had 3 or more electrocardiographic abnormalities (P = .04) than patients without CAD. During a median (IQR) follow-up period of 6.48 (2.44-11.20) years, 39% of patients reached an end point (death, n = 56; heart transplantation, n = 4). Mortality was 4.5% per year, and the rate of death or heart transplantation did not differ between patients with and without CAD (P = .26). Patients with 3-vessel disease had a worse prognosis than patients with 1- or 2-vessel disease (P = .046). In patients with LVHT, CAD does not appear to be associated with an increased rate of death or heart transplantation.

Perinatal outcomes and growth discordance of triplet pregnancies based on chorionicity: a retrospective cohort study

BackgroundThe worldwide occurrence of triplet pregnancy is estimated to be 0.093%, with a natural incidence of approximately 1 in 8000. This study aims to analyze the neonatal health status and birth weight discordance (BWD) of triplets based on chorionicity from birth until discharge.MethodsThis was a retrospective study. We reviewed a total of 136 triplet pregnancies at our tertiary hospital between January 1, 2001, and December 31, 2021. Maternal and neonatal outcomes, inter-triplet BWD, neonatal morbidity, and mortality were analyzed.ResultsAmong all cases, the rates of intrauterine death, neonatal death, and perinatal death were 10.29, 13.07, and 24.26%, respectively. Thirty-seven of the cases resulted in fetal loss, including 13 with fetal anomalies. The maternal complications and neonatal outcomes of the 99 triplet pregnancies without fetal loss were compared across different chorionicities, including a dichorionic (DC) group (41 cases), trichorionic (TC) group (37 cases), and monochorionic (MC) group (21 cases). Neonatal hypoproteinemia (P < 0.001), hyperbilirubinemia (P < 0.019), and anemia (P < 0.003) exhibited significant differences according to chorionicity, as did the distribution of BWD (P < 0.001). More than half of the cases in the DC and TC groups had a BWD < 15%, while those in the MC group had a BWD < 50% (47.6%). TC pregnancy decreased the risk of neonatal anemia (adjusted odds ratio [AOR] = 0.084) and need for blood transfusion therapy after birth (AOR = 0.119). In contrast, a BWD > 25% increased the risk of neonatal anemia (AOR = 10.135) and need for blood transfusion after birth (AOR = 7.127). TC pregnancy, MCDA or MCTA, and BWD > 25% increased neonatal hypoproteinemia, with AORs of 4.629, 5.123, and 5.343, respectively.ConclusionsThe BWD differed significantly according to chorionicity. Additionally, TC pregnancies reduced the risk of neonatal anemia and need for blood transfusion, but increased the risk of neonatal hypoproteinemia. In contrast, the BWD between the largest and smallest triplets increased the risk of neonatal anemia and the need for blood transfusion. TC pregnancy, MCDA or MCTA, and BWD > 25% increased the risks of neonatal hypoproteinemia. However, due to the limited number of triplet pregnancies, further exploration of the underlying mechanism is warranted.

Assessing the survival time of hospitalized patients in Eastern Ethiopia during 2019–2020 using the Bayesian approach: A retrospective cohort study

AbstractBackground and AimsSevere acute malnutrition remains a significant health challenge, particularly in low‐ and middle‐income countries. The aim of this study was to determine the survival time of under‐five children with severe acute malnutrition.MethodsA retrospective cohort study was conducted at a hospital, focusing on under‐five children with severe acute malnutrition. The study included 322 inpatients admitted to the Chiro hospital in Chiro, Ethiopia, between September 2019 and August 2020, whose data was obtained from medical records. Survival functions were analysed using Kaplan‒Meier plots and log‐rank tests. The survival time of severe acute malnutrition was further analysed using the Cox proportional hazards model and Bayesian parametric survival models, employing integrated nested Laplace approximation methods.ResultsAmong the 322 patients, 118 (36.6%) died as a result of severe acute malnutrition. The estimated median survival time for inpatients was found to be 2 weeks. Model selection criteria favored the Bayesian Weibull accelerated failure time model, which demonstrated that age, body temperature, pulse rate, nasogastric (NG) tube usage, hypoglycemia, anemia, diarrhea, dehydration, malaria, and pneumonia significantly influenced the survival time of severe acute malnutrition.ConclusionsThis study revealed that children below 24 months, those with altered body temperature and pulse rate, NG tube usage, hypoglycemia, and comorbidities such as anemia, diarrhea, dehydration, malaria, and pneumonia had a shorter survival time when affected by severe acute malnutrition under the age of five. To reduce the death rate of children under 5 years of age, it is necessary to design community management for acute malnutrition to ensure early detection and improve access to and coverage for children who are malnourished.

Reducing overdose deaths among persons with opioid use disorder in connecticut

BackgroundPeople in Connecticut are now more likely to die of a drug-related overdose than a traffic accident. While Connecticut has had some success in slowing the rise in overdose death rates, substantial additional progress is necessary.MethodsWe developed, verified, and calibrated a mechanistic simulation of alternative overdose prevention policy options, including scaling up naloxone (NLX) distribution in the community and medications for opioid use disorder (OUD) among people who are incarcerated (MOUD-INC) and in the community (MOUD-COM) in a simulated cohort of people with OUD in Connecticut. We estimated how maximally scaling up each option individually and in combinations would impact 5-year overdose deaths, life-years, and quality-adjusted life-years. All costs were assessed in 2021 USD, employing a health sector perspective in base-case analyses and a societal perspective in sensitivity analyses, using a 3% discount rate and 5-year and lifetime time horizons.ResultsMaximally scaling NLX alone reduces overdose deaths 20% in the next 5 years at a favorable incremental cost-effectiveness ratio (ICER); if injectable rather than intranasal NLX was distributed, 240 additional overdose deaths could be prevented. Maximally scaling MOUD-COM and MOUD-INC alone reduce overdose deaths by 14% and 6% respectively at favorable ICERS. Considering all permutations of scaling up policies, scaling NLX and MOUD-COM together is the cost-effective choice, reducing overdose deaths 32% at ICER $19,000/QALY. In sensitivity analyses using a societal perspective, all policy options were cost saving and overdose deaths reduced 33% over 5 years while saving society $338,000 per capita over the simulated cohort lifetime.ConclusionsMaximally scaling access to naloxone and MOUD in the community can reduce 5-year overdose deaths by 32% among people with OUD in Connecticut under realistic budget scenarios. If societal cost savings due to increased productivity and reduced crime costs are considered, one-third of overdose deaths can be reduced by maximally scaling all three policy options, while saving money.

Wound vacuum-assisted closure temporization after tumor resection of soft tissue sarcomas-A cost analysis in a propensity-score matched population.

Vacuum-assisted closure (VAC) temporization is a technique associated with high local control rates used in myxofibrosarcoma. We sought to compare the costs and postoperative outcomes of VAC temporization and single-stage (SS) excision/reconstruction. We conducted a retrospective analysis of patients with myxofibrosarcoma surgically treated at our institution between 2000 and 2022. Variables of interest included total, direct, and indirect costs for initial episode of care, 90 days and 1 year after initial admission, and postoperative outcomes. Costs were compared between the VAC temporization and SS groups. After matching, 13 patients in the SS group and 23 in the VAC group were analyzed. We found no difference in median and mean total inpatient costs, between the VAC temporization and SS group. While total 90-day and 1-year costs were higher in the VAC group compared to the SS group, mean costs were similar. There were no differences in postoperative complications between groups. A subanalysis of the entire cohort (n = 139) revealed lower local recurrence and overall death rates in the VAC temporization group. VAC temporization had similar inpatient costs and postoperative outcomes toSS excision/reconstruction. While median 90-day and 1-year costs were higher in the VAC group, mean costs did not differ.

MODELING THE SPREAD OF COVID-19 DISEASE WITH TIME DELAY IN PONTIANAK CITY

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by a coronavirus originating from the city of Wuhan in 2019. This disease affects the respiratory system. The city of Pontianak has the highest population density in West Kalimantan. This density results in a higher spread of Covid-19. In this article, the spread of COVID-19 is formulated into a mathematical model, equilibrium points are sought, stability is analyzed, and a delay time is introduced to reduce the spread of COVID-19. The magnitude of the delay time given during quarantine complies with health protocols, which is between 2 – 14 days. This article aims to analyze the influence of the delay time in modeling the spread of Covid-19. The problem of COVID-19 spread is constructed into an SIQR model, with a sub-population of recovered individuals returning to the susceptible sub-population. The population is divided into four sub-populations: susceptible (S), Infected (I), Quarantined (Q), and Recovered (R). The parameters used include the natural birth rate ( ), the rate of susceptibility to infection ( ), the rate of infection under quarantine ( ), the recovery rate from infection ( ), the recovery rate from infection under quarantine ( ), the death rate from infection ( ), the death rate under quarantine ( ), the delay time from infection to quarantine process ( ), the natural death rate ( ), and the rate of recovered immunity returning to susceptibility ( ). The simulation results show that when the basic reproduction number is less than , the disease-free equilibrium is stable, and when the basic reproduction number is greater than , the endemic equilibrium point is stable. The addition of a time delay ( ) in the SIQR model affects the stability of the endemic equilibrium point but does not affect the stability of the disease-free equilibrium point.

Worse outcomes in patients with cardiac sarcoidosis and involvement of the right ventricle in cardiac magnetic resonance

Abstract Background Cardiac sarcoidosis (CS) can manifest with variety of unspecific symptoms. It can mimic all types of cardiomyopathies but most often it resembles dilated cardiomyopathy. Involvement of right ventricle (RV) is rare and may lead to a false diagnosis of arrhythmogenic right ventricular cardiomyopathy and delay of the immunosuppressive therapy. Purpose The aim of this research was to study the characteristics and the outcomes of this peculiar subtype of patients. Methods We analyzed 112 patients diagnosed with CS after elaborate work-up with cardiac magnetic resonance (CMR), FDG PET and endomyocardial biopsy (EMB). All patients underwent follow-up for occurrence of combined endpoint of death, LV assist device implantation or heart transplantation. Patients with evidence of late gadolinium enhancement (LGE) involving RV (RV group) were identified and compared to the rest (DCM group) for baseline clinical characteristics, arhythmic outcomes and combined endpoint. Results Involvement of the RV in CMR was observed in 19 (17%) patients. Patients in the RV group were more frequently male: 84% vs. 57%, P = 0.032. EMB confirmed CS in 63% vs. 19.4% in the DCM group; P= 0.0001. LV ejection fraction in the RV group was comparable to the DCM group: 42±14% vs. 45±14%; P = 0.3. Furthermore, in the RV group the rates of sustained ventricular tachycardia were significantly higher than the DCM: 68% vs. 34%; P = 0.009. Long-term immunosuppressive therapy was started in 74% in RV and in 70% of the DCM group; P=0.77. Despite this, during follow-up, the rate of death, LVAD implantation or heart transplantation was significantly higher in the RV than in the DCM group; 26.3% vs. 7.5%; P = 0.03. In binary logistic analysis, the OR for the combined endpoint was 4.4; 95% CI 1.2-15.7. Conclusions Patients with CS and RV involvement in CMR have worse outcomes as compared to patients presenting as DCM, despite the comparable LV EF and immunosuppressive therapy.

One-year effectiveness and safety outcomes of edoxaban treatment in Chinese patients with atrial fibrillation: First snapshot of more than 4,800 patients from the ETNA-AF-China study

Abstract Background Direct oral anticoagulants (DOACs) have become the first-line therapy for ischaemic stroke prevention in atrial fibrillation (AF) patients. Data on the effectiveness and safety of single DOAC in large Chinese populations are scarce. Purpose We firstly present the one-year outcome data of edoxaban treatment in 5001 Chinese AF patients. Methods This is a multi-centre, prospective, observational study, ETNA-AF-China, conducted in 89 centres from four economic regions in Mainland of China with a follow-up of two years. Primary endpoint of safety [bleeding events including intracranial hemorrhage (ICH), all-cause and cardiovascular (CV) mortality] and efficacy endpoints [stroke, systemic embolic events (SEE), transient ischemic attack (TIA)] were adjudicated. Annualised event rates and Kaplan­Meier (KM) survival curves are given. Results A total of 4822 patients (57.1% male) using edoxaban (60 mg OD: n=2614, 30 mg OD: n=2208) who completed one-year follow-up were included in the full analysis set. The mean (SD) age of the overall patient population was 70.3 (9.5) years, CHA2DS2-VASc and HAS-BLED scores were 2.9 (1.4), 1.7 (1.0), with creatinine clearance (CrCl) of 71.2 (27.7) mL/min. Patients receiving 30 mg OD edoxaban at baseline were older (73.4 vs 67.7 years), with higher CHA2DS2-VASc score (3.3 vs 2.6), larger percentage of frail (9.9% vs 3.4%), and higher renal impairment (defined as CrCl ≤80 mL/min, 70.3% vs 42.9%). Annualised rates for all-cause and cardiovascular death in the overall population were very low with 2.22%/year and 0.41%/year, respectively. (Figure 1) The death rates were nearly three times lower in those receiving standard dose (60 mg) than reduction dose (30 mg) of edoxaban. Annualised event rates for all stroke/SEE (1.03%/year) and ischemic stroke (0.60%/year) were similar between two dose groups. Overall, annualised rates for major bleeding (1.03%/year), ICH (0.18%/year), major gastrointestinal (GI) bleeding (0.48%/year) events were relatively low, and those on 60 mg dose experienced less above bleeding events. Cumulative survival analysis demonstrated a slow increase in time-to-first event curve of all-cause death; and from baseline to 1-year follow-up, significant lower events of all-cause death (log-rank p&amp;lt;0.001), major bleeding (p=0.002) in 60 mg vs 30 mg edoxaban groups. (Figure 2). Conclusion Low incidences of major bleeding, notably ICH, major GI bleeding, and CV death were observed in unselected 4822 patients with AF during 1-year of edoxaban treatment. These findings confirm the effectiveness and safety of routine edoxaban use in China, consistent with other countries, and reinforce the results of the ENGAGE AF-TIMI 48 trial.Figure 1Figure 2
