Outcomes of controlled DCDD lung transplantation after thoraco-abdominal vs abdominal normothermic regional perfusion: The Spanish experience

ObjectiveThoraco-abdominal normothermic regional perfusion (TA-NRP) has emerged as a strategy for evaluating and recovering the heart in controlled donation after the circulatory determination of death (cDCDD). However, its impact on lung grafts remains largely unknown. We aimed to assess the impact of TA-NRP on the outcomes of recipients of cDCDD lungs. MethodsThis is a retrospective, multicenter, nationwide study describing the outcomes of cDCDD lung transplants (LTs) performed in Spain from January 2021 to November 2023. Patients were divided in two groups based on the recovery technique: TA-NRP with the simultaneous recovery of the heart versus abdominal NRP (A-NRP) without simultaneous heart recovery. The primary endpoint was the incidence of Primary Graft Dysfunction (PGD) grade 3 at 72 hours. Secondary endpoints included the overall incidence of PGD, days on mechanical ventilation, ICU and hospital length of stay, early survival rates, and mid-term outcomes. Results283 cDCDD LTs were performed during the study period, 28 (10%) using TA-NRP and 255 (90%) using A-NRP. No differences were observed in the incidence of PGD grade 3 at 72 hours between the TA-NRP and the A-NRP group (0% vs. 7.6%; p=0.231), though the overall incidence of PGD was significantly lower with TA-NRP (14.3%% vs. 41.5%; p=0.005). We found no significant differences between the groups regarding other post-transplant outcome variables. ConclusionsTA-NRP allows the simultaneous recovery of both the heart and the lungs in the cDCDD scenario with appropriate LT outcomes comparable to those observed with the A-NRP approach.

Association of aerobic and muscle-strengthening activity with chronic low back pain: population-based study

BACKGROUND CONTEXTChronic low back pain (CLBP) is a significant global health burden, primarily affecting the middle-aged and older; However, there is a lack of clear, evidence-based guidelines for leisure-time physical activity aimed at preventing CLBP. PURPOSEThis study sought to delineate the association between aerobic physical activity (APA) and muscle strengthening activities (MSA) and the prevalence of CLBP. STUDY DESIGNThis was a population-based study conducted across the United States. PATIENT SAMPLEThis nationwide study utilizes deidentified data from 22 consecutive rounds of the National Health Interview Survey (NHIS) from 1997 to 2018. OUTCOME MEASURESThe primary outcome was self-reported CLBP. METHODSWe analyzed the prevalence of CLBP in a representative sample of 324,793 middle-aged and older people. Among 263,871 individuals, we used multiple logistic regression to investigate individual and joint association between the amount of APA and MSA with CLBP. RESULTSIn total, 263,871 participants (mean age, 59.0 years; SD, 9.7) were included in the final analysis. From 1997 to 2018, the prevalence of CLBP was approximately 32%, with an annual increase. Engaging in APA for 75 to 150 minutes weekly was associated with a modest reduction in CLBP risk (OR [95% CI] = 0.97 [0.97–0.98]). Similar benefits were seen with 150 to 225, 225 to 300, and >300 minutes. Engaging in MSA 2 to 3 times and 4 to 5 times weekly also reduced CLBP risk (0.98 [0.98–0.99] and 0.98 [0.97–0.99], respectively). Optimal reductions of CLBP risk may be associated with balanced levels of APA and MSA, with recommended amounts being 225 to 300 min/w of APA and 4 to 5 times/w of MSA (0.92 [0.89–0.95]). CONCLUSIONSThe study found engaging in over 75 minutes of APA and 2 to 5 weekly MSA sessions is associated with a reduced risk of CLBP. Furthermore, a balanced combination of APA and MSA may correspond to the greatest reduction in CLBP risk.

Time trends in the clinical management of cervical intraepithelial neoplasia grade 2: A Danish register-based study.

Active surveillance for cervical intraepithelial neoplasia grade 2 (CIN2) has been implemented recently in many countries, including the Nordic countries. In Denmark, the only eligibility criterion for active surveillance for CIN2 is that the woman should be of reproductive age. With this study, we aimed to evaluate clinical and socioeconomic characteristics in women with CIN2 managed by active surveillance or large loop excision of the transformation zone (LLETZ) and to evaluate temporal changes in the clinical management of CIN2. We conducted a Danish nationwide study using data from healthcare registries. All female residents aged 18-40 years, diagnosed with incident CIN2 from January 1, 1998, to February 29, 2020, were included. We collected data on age, index cytology result, year of CIN2 diagnosis, region of residence, civil status, HPV vaccination status, and socioeconomic position indicators. The variables were tabulated overall and by management group (active surveillance vs. LLETZ). To evaluate time trends, we used joinpoint regression to calculate the annual percentage change (APC), including 95% confidence intervals (CI). Of the 27 536 women with CIN2 included, 12 500 (45.4%) underwent active surveillance, and 15 036 (54.6%) underwent a LLETZ. Women undergoing active surveillance were younger, more often HPV-vaccinated, and more likely to have a normal/low-grade index cytology result than women undergoing LLETZ. Socioeconomic position indicators did not differ. Over time, the proportion of women undergoing active surveillance increased from 21.7% in 2004 to 73.6% in 2019 (APC 9.7, 95% CI 8.1-11.4). The proportion of women undergoing active surveillance aged <30 declined over time (APC -2.2, 95% CI -2.9 to -1.5). The proportion of women with normal/low-grade index cytology increased slightly to 51.6% in 2019 (APC 0.8, 95% CI 0.4-1.3). The use of active surveillance for CIN2 has increased over the past two decades in Denmark. Observed differences in characteristics between women undergoing active surveillance vs LLETZ are likely related to indications for clinical management.

Heart failure treatment in the last years of life: A nationwide study of 364 000 individuals.

In patients with heart failure, treatment patterns in the last years of life have not been assessed at large scale. We aimed to assess whether heart failure treatment patterns up to 5 years prior to death changed over time. In a cohort study covering the whole Swedish population, we assessed all heart failure patients who died between 1 July 2007 and 31 December 2020 for evidence-based treatments. The proportion on the respective treatment at the time of death was examined by year of death using binomial regression. Looking back in time, treatment discontinuation rates were estimated using Poisson regression on time-split data. Combining these models, the proportion on each medication was estimated up to 5 years prior to death. A total of 364 480 patients died with heart failure during the study period. Half were women, and the median (interquartile range) age at death was 86 (79-90). The use of all heart failure treatments decreased gradually closer to death, but the discontinuation rate of beta blockers decreased over time, resulting in an increasing proportion of patients on treatment at the time of death. In patients with heart failure, a changing pattern of medical treatment during the last years of life was observed, most notably with an increasing use of beta blockers. This may in part be due to a changing pattern of comorbidities over time, with an increase in e.g. hypertension and atrial fibrillation, but a decline in ischaemic heart disease.

Insights on feline infectious peritonitis risk factors and sampling strategies from polymerase chain reaction analysis of feline coronavirus in large-scale nationwide submissions.

This nationwide study aimed to investigate risk factors associated with FIP and determine optimal sample submission strategies for its diagnosis. A total of 14,035 clinical samples from cats across the US were analyzed by means of reverse transcriptase quantitative PCR to detect replicating feline coronavirus (FCoV). χ2 and logistic regression analyses were conducted to assess the association between FCoV detection rates and risk factors such as age, gender, breed, and types of submitted samples. Higher FCoV detection rates were observed in younger cats, particularly those aged 0 to 1 year, and in male cats. Purebred cats, notably British Shorthairs [OR: 2.81; P < .001], showed a higher incidence of FCoV infection than other cats. Peritoneal fluid (OR, 7.51; P < .001) exhibited higher FCoV detection rates than other samples, while lower rates were seen in blood samples (OR, 0.08; P < .001) than in other samples. High FCoV detection rates were found in urine, kidney, and lymph node samples. The study identified significant risk factors associated with FIP. Optimal sample submission strategies, particularly emphasizing the use of peritoneal fluid, kidney, and lymph node, were identified to improve FIP detection rates. Urine yielded a relatively high frequency of infection and viral loads compared with most other samples. Understanding the risk factors and optimizing sample selection for FIP diagnosis can aid in the early detection and management of the disease, ultimately improving outcomes for affected cats. These findings contribute valuable insights to FIP epidemiology and underscore the importance of continued research to enhance diagnostic strategies and disease management approaches.

Increasing opportunities for breast-conserving therapy in multiple ipsilateral breast cancer: Dutch nationwide study.

An increasing number of breast cancer patients undergo breast-conserving surgery (BCS), but multiple ipsilateral breast cancer (MIBC) is still considered a relative contraindication for breast conservation. This study provides an update on trends in the surgical management for MIBC over a 10-year period. Nationwide data from the Netherlands Cancer Registration of all patients diagnosed with breast cancer between 2011 and 2021 were analysed. The primary outcomes of this study were the incidence of MIBC and the trend in breast surgery type among patients between 2011 and 2021. Secondary outcomes were the positive resection margin rates in patients treated with BCS, the proportion of patients requiring re-excision and overall survival. In total, 114 433 patients (83%) with unifocal breast cancer and 23 932 patients (17%) with MIBC were identified. The incidence of MIBC was stable (17%) over the years. Overall BCS rates, both primary and after neoadjuvant chemotherapy, increased in MIBC from 29% in 2011 to 41% in 2021. Re-excision was performed in 1348 patients (n = 8455, 16%). The 5-year OS estimate for patients with MIBC treated with BCS was 93%. The pathological complete response (pCR) in MIBC patients treated with neoadjuvant chemotherapy followed by mastectomy was 23%. The breast conservation rate in MIBC has increased over the last decade. In addition, 23% of MIBC patients treated with neoadjuvant chemotherapy followed by mastectomy achieved a pCR. This suggests increasing opportunities for even more BCS in MIBC.

Elevated Fracture Risks in Patients Using Inhaled Corticosteroids: A Korean Nationwide Study.

In this comprehensive retrospective nationwide cohort study, we examined the relationships between various asthma medications and bone health, utilizing data from the National Health Insurance Service database of South Korea. From 2015 to 2019, the relevant dataset included 168,611 individuals aged 66 years, among whom 8,747 were diagnosed with asthma. We focused on a subset of 6,173 patients, all 66-year-old women. Participants were categorized into four groups: nonusers of asthma medication (n=2,868), leukotriene antagonist users (n=2,281), inhaled corticosteroid (ICS) users (n=517), and those using a combination of ICS and long-acting beta-agonist (ICS+LABA) medication (n=507). The primary outcomes measured were the incidences of major osteoporotic fractures and hip fractures during the follow-up period. Over 2.7 years of follow-up, 615 cases of major osteoporotic fractures and 96 cases of hip fractures were recorded. ICS users exhibited a heightened risk of both injuries, with hazard ratios of 1.38 (95% confidence interval [CI], 1.18 to 1.63; P<0.001) for major osteoporotic fractures and 1.56 (95% CI, 1.33 to 1.83; P<0.001) for hip fractures. Similarly elevated risks were observed in the ICS+LABA group. Notably, the risk associated with ICS was particularly pronounced among patients with osteopenia for both fracture types. Overall, the use of ICS, alone or in combination with LABA, in patients with asthma is associated with significantly increased risks of osteoporotic fractures, especially among those with osteopenia. These findings underscore the importance of considering bone health when managing asthma, especially in older patients and those with existing bone density issues.

Temporal trends in infection-related hospitalizations among patients with heart failure: A Danish nationwide study from 1997 to 2017

BackgroundDespite improved survival, hospitalization is still common among patients with heart failure (HF). ObjectiveThis study aimed to examine temporal trends in infection-related hospitalization among HF patients and compare it to temporal trends in the risk of HF hospitalization and death. MethodsUsing Danish nationwide registers, we included all patients aged 18-100 years, with HF diagnosed between 1st January 1997 and 31st December 2017, resulting in a total population of 147.737 patients. The outcomes of interest were primarily infection-related hospitalization and HF hospitalization and secondarily all-cause mortality. The Aalen Johansen's estimator was used to estimate five-year absolute risks for the primary outcomes. Additionally, cox analysis was used for adjusted analyses. ResultsThe population had a median age of 74 [64, 82] years and 57.6 % were males. Patients with HF had a higher risk of infection over time 16.4 % (95% CI 16.0–16.8) in 1997–2001 vs. 24.5% (95% CI 24.0–24.9) in 2012–2017. In contrast, they had a lower risk of HF hospitalization 26.5% (95% CI 26.1–27.0) in 1997–2001 vs. 23.2% (95% CI 22.8–23.7) in 2012–2017. The risk of infection stratified by infection type showed similar trends for all infection types and marked the risk of pneumonia infection as the most significant in all subintervals. ConclusionIn the period from 1997 to 2017, we observed patients with HF had an increased risk of infection-related hospitalization, driven by pneumonia infections. In contrast, the risk of HF hospitalization decreased over time.

A nationwide study of heavy metal(loid)s in agricultural soils and the soil-grown black morel Morchella sextelata in China

The accumulation of heavy metal(loid)s (HMs) in soil-grown mushrooms poses potential health risks. Morchella sextelata (black morel) is a typical soil-grown mushroom with a rapidly expanding cultivation area. This study investigated the distribution of arsenic, cadmium, chromium, copper, mercury, nickel, lead, and zinc in 213 pairs of soil and morel samples collected from 29 provincial administrative regions in China, together with the nutritional contents in the morel samples. The HM contents in the arable soils used to cultivate morels were 2.4–33.1 times higher than those in desert soils, while the HM contents in arable-soil morels were 2.9–155.9 times higher than desert morels. The HM contents of morels and their cultivation soils were significantly correlated (0.465 ≤ R ≤ 0.778, P < 0.001). Furthermore, the enrichment factors of most HMs were higher in arable soils than in desert soils (P < 0.05), except Hg. A considerable proportion of the arable soils produced morels with HMs exceeding the risk control standards (RCSs) for food and the health-risk thresholds of dietary intake. In comparison, HMs in morels from desert soils were far below the RCSs and health-risk thresholds. In addition, desert morels contained higher contents of crude proteins, total polysaccharides, and free amino acids (P < 0.001). These findings indicate that growing morels in desert soils is a way of green production that provides mushroom products with improved safety and nutrition.

Risk of hospitalization with infection in adults with primary AIHA treated with rituximab: a French nationwide study

AbstractAutoimmune hemolytic anemia (AIHA) is a rare and sometimes life-threatening disease. Infections are frequent and often severe during the course of AIHA. Rituximab is commonly used to treat patients with AIHA. This study aimed to assess the risk of hospitalization with infection after rituximab in patients with primary AIHA. We selected all adult patients newly diagnosed for primary AIHA and treated with rituximab between 2012 and 2018 in the French national health database. Patients were considered exposed to rituximab within 6 months after the first infusion. The main outcome was hospitalization with infection, identified by a discharge diagnosis of infection during the rituximab exposure. The cohort consisted of 959 patients (mean age of 67 years, standard deviation of 17.8 years; 60.5% of women). The 6-month cumulative incidence of hospitalization with infection was 17.6% (95% confidence interval [CI], 15.2-20.0). The most frequently characterized infections were pulmonary (40.2%). Opportunistic infections were observed in 28 (16.6%) patients, including 11 cases of pneumocystosis. All cases of pneumocystosis occurred in patients concomitantly exposed to corticosteroids, none of them had prophylaxis and all but 2 were aged ≥70 years. Overall, the main factors associated with hospitalization with infection were an age ≥70 years and the exposure to corticosteroids. The 30-day overall mortality after hospitalization with infection was 12.5% (95% CI, 8.0-18.0). In conclusion, the incidence of hospitalizations with infection, including opportunistic infections, as well as the subsequent mortality, are high in adult patients with primary AIHA treated with rituximab. Pneumocystosis prophylaxis should be encouraged in elderly patients exposed to corticosteroids.

Weight Change After Cancer Diagnosis and Risk of Diabetes Mellitus: A Population-Based Nationwide Study.

Cancer survivors are at increased risk of diabetes mellitus (DM). Additionally, the prevalence of obesity, which is also a risk factor for DM, is increasing in cancer survivors. We investigated the associations between weight change after cancer diagnosis and DM risk. This retrospective cohort study used data from the Korean National Health Insurance Service. Participants who were newly diagnosed with cancer from 2010 to 2016 and received national health screening before and after diagnosis were included and followed until 2019. Weight change status after cancer diagnosis was categorized into four groups: sustained normal weight, obese to normal weight, normal weight to obese, or sustained obese. Cox proportional hazard analyses were performed to examine associations between weight change and DM. The study population comprised 264,250 cancer survivors. DM risk was highest in sustained obese (adjusted hazard ratios, 95% confidence interval: 2.17, 2.08-2.26), followed by normal weight to obese (1.66, 1.54-1.79), obese to normal weight (1.29, 1.21-1.39), and then sustained normal weight group (reference). In subgroup analyses according to cancer type, most cancers showed the highest risks in sustained obese group. Obesity at any time point was related to increased DM risk, presenting the highest risk in cancer survivors with sustained obesity. Survivors who changed from obese to normal weight had lower risk than survivors with sustained obesity. Survivors who changed from normal weight to obese showed increased risk compared to those who sustained normal weight. Our finding supports the significance of weight management among cancer survivors.

On actual carpooling behaviour: a nationwide study in Spain

ABSTRACT Carpooling is a powerful tool to reduce the total number of car trips and associated CO2 emissions. Hence, factors influencing carpooling have been extensively researched. However, most studies have been limited in geographic scope, relied on low-quality surveys, and focused on declared intentions rather than actual behaviour. The current study used a well-designed, nationwide survey that captures actual carpooling behaviour. To estimate the impact of three novel variables: having a solar panel at home (a measure of eco-awareness), a fuel-effort indicator (a measure of the relative cost of filling a car fuel tank), and the degree of participation in social networks (a measure of social trust and tech savviness), we developed a binary logistic regression model adjusting for multiple control variables identified as relevant in systematic reviews. Our analysis confirmed the relevance of most control variables and showed all three variables had a significant effect on individuals’ likelihood of carpooling. These findings imply that policies that are not originally intended to encourage carpooling could boost it indirectly.

Change in Liver Function in Durvalumab Plus Tremelimumab Treatment for Unresectable Hepatocellular Carcinoma.

Maintaining liver function throughout the treatment of hepatocellular carcinoma (HCC) is crucial, yet the impact of durvalumab plus tremelimumab (DT) treatment on liver function is not well understood. This multicenter study aimed to examine the changes in liver function during DT treatment. This nationwide multicenter study included 80 patients who received DT treatment for unresectable HCC. The primary outcome was changes in albumin-bilirubin (ALBI) scores at baseline, week 8, week 12, and at the time of progressive disease (PD). The median (interquartile range) ALBI scores at baseline, week 8, week 12, and the time of PD were -2.24 (-2.49 to -1.94), -2.13 (-2.51 to -1.86), -2.23 (-2.51 to - 1.77), and -2.06 (-2.53 to -1.72), respectively. No significant differences were observed at 8 weeks (p=0.06), at 12 weeks (p=0.4), and at PD (p=0.8) compared to baseline. Subgroup analyses were conducted for patients with an ALBI grade of 2 at baseline and for those who received DT treatment as a second-line or later treatment. No deterioration in liver function was observed at any time point in both analyses. DT treatment can maintain liver function throughout the treatment period. Maintaining liver function is crucial in managing HCC, and this is an advantage of using DT treatment as a first-line treatment for unresectable HCC.

Botulinum toxin for bruxism treatment: a nationwide study among oral and maxillofacial surgeons in Germany.

This study aimed to evaluate the use of botulinum toxin (BTX) for the treatment of bruxism in oral and maxillofacial surgery in Germany. A dynamic online questionnaire comprising 7 to 25 questions was formulated to gather general and specific information regarding using BTX to treat bruxism. The questionnaire underwent internal and external assessments for validation. Subsequently, it was distributed to 906 oral and maxillofacial surgeons (OMFS) affiliated with the German Association for Oral and Maxillofacial Surgery (DGMKG). Weekly reminders were dispatched over four weeks to enhance response rates. Participation in the study was voluntary and anonymized. Descriptive methods were employed for data analysis. 107 OMFS participated in the study, yielding a response rate of 11.81%. On average, 17 patients with bruxism were per month, with 4 of these patients receiving BTX therapy. BTX administration was frequently accompanied by splints and physiotherapy (35.51% of participants). Botox® (Allergan) was the preferred BTX preparation, utilized by 40.79% and reconstituted with saline by 92.11% of participants. The masseter muscles were primarily targeted for BTX treatment (67.57% of participants), averaging 29 BTX (Allergan-) units per side. Injection points for each masseter muscle typically amounted to six per side, preferred by 30.67% of participants. Follow-up assessments post-BTX treatment were conducted regularly, predominantly after four weeks, by 36% of participants. In 8% of cases, additional BTX injections were necessary due to inadequate outcomes. Side effects were reported in 4% of cases, commonly manifesting as a non-disturbing reduction in bite force. Most participating OMFS (61.84%) using BTX for bruxism therapy regarded bruxism treatment with BTX as evidence-based. Notably, 97.37% of respondents expressed their willingness to recommend BTX-based bruxism treatment to their colleagues. Overall, the efficacy of BTX therapy for bruxism was rated as good (53.95%) and very good (40.79%). The use of BTX for the management of bruxism among OMFS in Germany has demonstrated efficacy. Substantial variances in certain facets of bruxism treatment employing BTX have been observed. Additional research endeavors are warranted to comprehensively investigate distinct elements of BTX therapy for bruxism, including the optimal dosage of BTX units and the precise localization of injection sites across various muscles.

Exploring the Impact of Family History, Demographics and Ecological Factors on Urolithiasis Prevalence: Insights from a Nationwide Study.

This study aimed to evaluate the potential risk factors of lifetime urolithiasis occurrence on a nationwide scale in Iran. All data regarding urinary stone events were extracted from the cross-sectional Iran National Stone Survey (INSS) study, and the possible determinants of urolithiasis incidence were evaluated. Our multivariable logistic regression suggested that while older age at presentation, male sex, and a positive family history of urolithiasis in either of the patient's parents or siblings were all significantly associated with an increased odds of lifetime urolithiasis occurrence (all P < .001), a positive family history in one's sister (odds ratio; OR=5.56) or brother (OR=4.70) were the most significant predictors. Moreover, belonging to Baluch ethnicity (i.e., an ethnical group indigenous to the south eastern regions of Iran) and residing in regions with higher water hardness (i.e., total concentration of dissolved minerals) were also associated with an increased odds of urolithiasis occurrence (P < .001 and P=.023, respectively). Conversely, living in regions with higher mean humidity decreased the chances of developing a urinary stone event during one's lifetime (OR=0.62, P <.001). Our results indicated that a constellation of demographic, ecological, and familial risk factors are associated with an elevated risk of developing urinary stones during one's lifetime. These findings can assist in implementing novel regional healthcare policies, considering the specific demographic and ecological characteristics. They also support tailoring personalized preventive strategies, particularly for individuals with multiple nonmodifiable risk factors.

Threshold effect of physical exercise on its association to diabetes mellitus in short sleep population: evidence from a nationwide study.

The prevalence of diabetes mellitus (DM) is a significant public health concern, especially among individuals with short sleep duration. Understanding the relationship between physical exercise and DM in this population is crucial for developing effective prevention strategies. However, the presence of a potential threshold effect of exercise on DM risk remains unclear. Using data from the National Health and Nutrition Examination Survey (NHANES) spanning from 2007 to 2018, this population-based study investigated the association between physical exercise and DM in individuals with short sleep duration (no more than 7 hours per night). Weighted logistic regression analyses were conducted, adjusting for demographic and lifestyle factors. Additionally, a two-piecewise linear regression model was employed to identify any threshold effect of exercise on DM risk. This study included 15,092 participants identified with short sleep duration. Demographic characteristics stratified by DM status indicate higher prevalence among certain groups, such as middle-aged and older adults, males, and non-Hispanic Whites. The analysis revealed an inverse association between exercise levels and DM prevalence among the short sleep population. In the fully adjusted model, individuals engaging in sufficient exercise (> 600 MET-minutes/week) exhibited significantly reduced odds of developing DM [OR (95% CI): 0.624(0.527,0.738), p < 0.001]. Furthermore, the segmented regression model identified an inflection point at 2000 MET-minutes/week, below which a significant correlation between exercise and DM was observed. This study provides evidence of a threshold effect of physical exercise on its association with DM in individuals with short sleep duration. Tailored exercise interventions targeting this population may help mitigate DM risk and improve overall health outcomes. Further research is warranted to validate these findings and explore optimal exercise thresholds for DM prevention strategies.

Modern heart failure treatment is superior to conventional treatment across the left ventricular ejection spectrum: real-life data from the Swedish Heart Failure Registry 2013–2020

ObjectivesThis study is aimed to compare the effectiveness of modern therapy including angiotensin receptor-neprilysin inhibitor (ARNI) and sodium-glucose cotransporter 2 inhibitors (SGLT2i) with conventional heart failure treatment in the real world.BackgroundSince ARNI and SGLT2i were introduced to treat heart failure (HF), its therapeutic regimen has modernized from previous treatment with beta-blocker (BB) and angiotensin-converting enzyme inhibitor (ACEi)/angiotensin II receptor blocker (ARB) with mineralocorticoid receptor antagonist (MRA) as added-on in HF with reduced ejection fraction (HFrEF). However, a comparison between conventional and modern treatment strategies with drugs in combination has not been performed.MethodsThis observational study (2013–2020), using the Swedish HF Registry, involved 20,849 HF patients. Patients received either conventional (BB, ACEi/ARB, with/without MRA, n = 20,140) or modern (BB, ACEi/ARB, MRA, SGLT2i or BB, ARNI, MRA with/without SGLT2i, n = 709) treatment at the index visit. The endpoints were all-cause and cardiovascular (CV) mortality.ResultsModern HF therapy was associated with a significant 28% reduction in all-cause mortality (adjusted HR [aHR], 0.72 (0.54–0.96); p = 0.024) and a significant 62% reduction in CV mortality (aHR, 0.38 (0.21–0.68); p = 0.0013) compared to conventional HF treatment. Similar results emerged in a sensitivity analysis using propensity score matching. The interaction analyses did not reveal any trends for EF (< 40% and ≥ 40%), sex, age (< 70 and ≥ 70 years), eGFR (< 60 and ≥ 60 ml/min/1.73 m2), and etiology of HF subgroups.ConclusionIn this nationwide study, modern HF therapy was associated with significantly reduced all-cause and CV mortality, regardless of EF, sex, age, eGFR, and etiology of HF.Graphical abstract

Effectiveness of chest pain center accreditation on the hospital outcome of acute aortic dissection: a nationwide study in China

BackgroundThe National Chest Pain Center Program (NCPCP) is a nationwide, quality enhancement program aimed at raising the standard of care for patients experiencing acute chest pain in China. The benefits of chest pain center (CPC) accreditation on acute coronary syndrome have been demonstrated. However, there is no evidence to indicate whether CPC accreditation improves outcomes for patients with acute aortic dissection (AAD).MethodsWe conducted a retrospective observational study of patients with AAD from 1671 hospitals in China, using data from the NCPCP spanning the period from January 1, 2016 to December 31, 2022. The patients were divided into 2 groups: pre-accreditation and post-accreditation admissions. The outcomes examined included in-hospital mortality, misdiagnosis, and Stanford type A AAD surgery. Multivariate logistic regression was employed to explore the relationship between CPC accreditation and in-hospital outcomes. Furthermore, we stratified the hospitals based on their geographical location (Eastern/Central/Western regions) or administrative status (provincial/non-provincial capital areas) to assess the impact of CPC accreditation on AAD patients across various regions.ResultsThe analysis encompassed a total of 40,848 patients diagnosed with AAD. The post-accreditation group exhibited significantly lower rates of in-hospital mortality and misdiagnosis (12.1% vs. 16.3%, P < 0.001 and 2.9% vs. 5.4%, P < 0.001, respectively) as well as a notably higher rate of Stanford type A AAD surgery (61.1% vs. 42.1%, P < 0.001) compared with the pre-accreditation group. After adjusting for potential covariates, CPC accreditation was associated with substantially reduced risks of in-hospital mortality (adjusted OR 0.644, 95% CI 0.599–0.693) and misdiagnosis (adjusted OR 0.554, 95% CI 0.493–0.624), along with an increase in the proportion of patients undergoing Stanford type A AAD surgery (adjusted OR 1.973, 95% CI 1.797–2.165). Following CPC accreditation, there were significant reductions in in-hospital mortality across various regions, particularly in Western regions (from 21.5 to 14.1%). Moreover, CPC accreditation demonstrated a more pronounced impact on in-hospital mortality in non-provincial cities compared to provincial cities (adjusted OR 0.607 vs. 0.713).ConclusionCPC accreditation is correlated with improved management and in-hospital outcomes for patients with AAD.

Regional variations in psoriatic arthritis: Insights from a nationwide multicenter analysis in Türkiye

Objectives: The study aimed to investigate and compare clinical features, disease activity, and the overall disease burden among psoriatic arthritis (PsA) patients across seven distinct geographic regions in Türkiye. Patients and methods: A multicenter cross-sectional study involving 1,134 PsA patients from 25 referral centers across seven regions was conducted. Demographic and clinical characteristics, comorbidities, joint involvement, extra-articular manifestations, and disease activity measures were evaluated across regions. Results: A total of 1134 PsA patients from seven different geographic regions in Türkiye participated in this study. The highest number of participants was from the Marmara region (n=409), with subsequent representation from Central Anatolia (n=370), Aegean (n=139), Mediterranean (n=60), Black Sea (n=60), Eastern Anatolia (n=60), and Southeastern Anatolia (n=36) regions. There were significant variations in demographic profile, including age, body mass index, age of disease onset, educational status, comorbidities, and family history of both psoriasis and PsA. Clinical features, such as enthesitis, dactylitis, uveitis, and joint involvement, demonstrated significant variation across regions. Additionally, disease activity measures, including pain, patient and physician global assessments, acute phase reactants, disease activity indices, quality of life, and functional status, displayed considerable regional differences. Conclusion: This nationwide study revealed substantial regional diversity in demographic data, clinical characteristics, disease activity, and quality of life among PsA patients in Türkiye. These findings stress the need to customize treatment approaches to address regional needs and to conduct further research to uncover reasons for disparities. It is crucial to enhance region-specific approaches to improve patient care and outcomes for PsA.
