ABSTRACT
PURPOSE: Meningeal solitary fibrous tumour (SFT) and haemangiopericytoma (HPC) are uncommon tumours that have been merged into a single entity in the last 2021 WHO Classification of Tumors of the Central Nervous System. To describe the epidemiology of SFT/HPC operated in France and, to assess their incidence. METHODS: We processed the French Brain Tumour Database (FBTDB) to conduct a nationwide population-based study of all histopathologically confirmed SFT/HPC between 2006 and 2015. RESULTS: Our study included 399 SFT/HPC patients, operated in France between 2006 and 2015, in one of the 46 participating neurosurgical centres. The incidence reached 0.062, 95%CI[0.056-0.068] for 100,000 person-years. SFT accounted for 35.8% and, HPC for 64.2%. The ratio of SFT/HPC over meningioma operated during the same period was 0.013. SFT/HPC are about equally distributed in women and men (55.9% vs. 44.1%). For the whole population, mean age at surgery was 53.9 (SD ± 15.8) years. The incidence of SFT/HPC surgery increases with the age and, is maximal for the 50-55 years category. Benign SFT/HPC accounted for 65.16%, SFT/HPC of uncertain behaviour for 11.53% and malignant ones for 23.31%. The number of resection progresses as the histopathological behaviour became more aggressive. 6.7% of the patients with a benign SFT/HPC had a second surgery vs.16.6% in case of uncertain behaviour and, 28.4% for malignant SFT/HPC patients. CONCLUSION: Meningeal SFT and HPC are rare CNS mesenchymal tumours which both share common epidemiological characteristics, asserting their merging under a common entity. SFT/HPC incidence is less that one case for 1 billion per year and, for around 100 meningiomas-like tumours removed, one SFT/HPC may be diagnosed. SFT/HPC are equally distributed in women and men and, are mainly diagnosed around 50-55 years. The more aggressive the tumour, the higher the probability of recurrence.

BACKGROUND: Acute exacerbations of COPD (AECOPDs) are increasingly recognized as episodes of heightened risk of cardiovascular events. It is not known whether exacerbation history is differentially associated with future myocardial infarction (MI) or pulmonary embolism (PE). RESEARCH QUESTION: Is the number and severity of AECOPDs associated with increased risk of MI or PE in a real-life cohort of patients with COPD? STUDY DESIGN AND METHODS: We identified a cohort of 66422 patients (≥30yr) with a primary diagnosis of COPD in the Swedish National Airway Register January 2014 to June 2022, with complete data on lung function. Patients were classified by moderate (prescription of oral corticosteroids) and severe (hospitalization) exacerbations the year before index date and were followed until Dec 2022 for hospitalization or death from MI or PE, corresponding to >265 000 patient-years, with a maximum follow-up time of 9 years. Competing-risk regression, according to Fine-Gray, was used to calculate subdistribution hazard ratios (SHRs) with 95% confidence intervals (CI). RESULTS: Compared with no AECOPDs in the baseline period, AECOPD number and severity was associated with increased long term risk of both MI and PE in a gradual fashion, ranging from a SHR of 1.10 (0.97-1.24) and 1.33 (1.11-1.60), respectively, for one moderate exacerbation, to 1.82 (1.36-2.44) and 2.62 (1.77-3.89), respectively, for two or more severe exacerbations. In a time-restricted follow-up sensitivity analysis, the associations were stronger during the first year of follow up and diminished over time. INTERPRETATION: The risk of MI and PE increases with the frequency and severity of AECOPD in this large real life cohort of patients with COPD.
ABSTRACT
Background: The COVID-19 pandemic underscored the critical importance of biosafety in microbiology laboratories worldwide. In response, China has ramped up its efforts to enhance biosafety measures within its Centers for Disease Control and Prevention (CDC) laboratories. This study provides the first comprehensive assessment of biosafety practices across provincial, city, and county levels of CDC microbiology laboratories in China. Methods: We conducted a nationwide cross-sectional survey from 2021 to 2023, targeting staff from microbiology laboratories within CDCs at all administrative levels in China. Stratified sampling was employed to select respondents, ensuring a representative mix across different CDC hierarchies, job titles, and academic qualifications. The survey encompassed questions on biosafety training, the presence of BSL-2 and BSL-3 laboratories, adherence to general biosafety guidelines, and management practices regarding specimens, reagents, and consumables. Statistical analysis was performed to identify significant differences in biosafety practices among different CDC levels. Results: A total of 990 valid responses were received, highlighting a nearly universal presence (98.69%) of BSL-2 laboratories and a significant yet varied presence of BSL-3 laboratories across the CDC network. The survey revealed high levels of biosafety training (98.69%) and adherence to biosafety protocols. However, challenges remain in the consistent application of certain safety practices, especially at lower administrative levels. Notable differences in the management of specimens, reagents, and consumables point to areas for improvement in ensuring biosecurity. Conclusion: Our findings indicate a robust foundation of biosafety practices within CDC microbiology laboratories in China, reflecting significant advancements in the wake of the Biosecurity Law's implementation. Nevertheless, the variability in adherence to specific protocols underscores the need for ongoing training, resources allocation, and policy refinement to enhance biosafety standards uniformly across all levels. This study's insights are crucial for guiding future improvements in laboratory biosafety, not just in China but potentially in other countries enhancing their public health infrastructures.

BACKGROUND: Postoperative delirium (POD) is a common surgical complication. However, the incidence and risk factors associated with postoperative delirium after revision total knee arthroplasty (rTKA) have not been comprehensively explored through extensive national databases. METHODS: Utilizing the National Inpatient Sample (NIS), the largest comprehensive U.S. hospital healthcare database, we undertook a retrospective investigation involving 127,400 patients who underwent rTKA between 2010 and 2019. We assessed various aspects, including patient demographics, hospital characteristics, pre-existing medical conditions, and perioperative complications. RESULTS: The overall incidence of postoperative delirium (POD) in patients undergoing rTKA between 2010 and 2019 was 0.97%. The highest incidence rate of 1.31% was recorded in 2013. Notably, this patient cohort demonstrated advanced age, increased burden of co-morbidities, prolonged hospital stays, increased hospitalization costs, and elevated in-hospital mortality rates (P < 0.001). Moreover, non-elective admissions, non-private insurance payments, and a preference for teaching hospitals were commonly observed among these patients. During their hospitalization, individuals who developed delirium subsequent to rTKA were more prone to experiencing certain perioperative complications. These complications encompassed medical issues like acute myocardial infarction, continuous invasive mechanical ventilation, postoperative shock, sepsis, stroke and other medical problems. Additionally, surgical complications including hemorrhage / seroma / hematoma, irrigation and debridement, prosthetic joint infection, periprosthetic fracture, and wound dehiscence / nonunion were noted. Several risk factors were found to be linked with the development of POD. These included advanced age (≥ 75 years), alcohol abuse, coagulation disorders, congestive heart failure, depression, fluid and electrolyte imbalances, and more. Conversely, female sex, having private insurance, and undergoing elective hospitalization emerged as protective factors against POD. CONCLUSION: Our findings suggest that the general prevalence of POD in rTKA is relatively low according to NIS. There was a significant connection between the POD of rTKA and advanced age, prolonged length of stay (LOS), more in-patients' costs, higher in-hospital mortality rate, increased comorbidities, postoperative medical complications and postoperative surgical complications. This study helps to understand the risk factors associated with POD to improve poor outcomes.

BACKGROUND: We conducted a nationwide survey of persistent cloaca (PC) to investigate the renal function outcomes and factors affecting chronic kidney disease (CKD) in patients with PC. METHOD: Information from 466 patients with PC was obtained via a questionnaire in this study. The 290 patients (62.2%) with renal function data were classified into 2 groups based on their estimated glomerular filtration rate: advanced CKD group (<30 mL/min/1.73 m2 [or post-renal replacement therapy]) and non-advanced CKD group (≥30 mL/min/1.73 m2). Univariate and multivariate analyses were performed to identify risk factors for CKD that may affect the renal function, including renal and urinary tract malformations, associated anomalies, and urinary tract treatment. The advanced CKD group was divided into two groups based on age to evaluate age-related differences (younger- and older-age CKD groups). RESULTS: A regression analysis revealed that congenital renal malformations (odds ratio [OR]: 14.06, 95% confidence interval [CI]:3.07-131.65, p < 0.0001), urinary tract obstruction (OR:4.28, 95%CI:1.12-24.23, p < 0.05), and sacral agenesis (OR:4.54, 95% CI:0.84-30.67, p < 0.05) were significantly associated with advanced CKD. In the univariate analysis of factors affecting the renal prognosis, clean intermittent catheterization (CIC) (OR:4.18, 95%CI:1.21-16.45, p = 0.015), vesicostomy (OR:3.65, 95%CI:1.11-12.98, p = 0.019), and surgery for vesicoureteral reflux (OR:5.43, 95%CI:1.41-22.73, p = 0.006) were significantly associated with advanced CKD. Based on the univariate analysis, hydrometrocolpos was significantly more prevalent in the older-age CKD group compared to the younger-age CKD group (p < 0.05). CONCLUSION: CKD development in patients with PC is influenced by a complex interplay of factors, including renal malformations and neurogenic bladder dysfunction due to spinal anomalies. LEVEL OF EVIDENCE: III (Study of Diagnostic Test, Study of nonconsecutive patients, and/or without a universally applied "gold" standard).
ABSTRACT
This research investigated spatial inequalities in transportation accessibility to social infrastructures (SIs) in South Korea, using a multi-dimensional methodological approach, including descriptive/bivariate analysis, explanatory factor analysis (EFA), K-Mean cluster analysis, and multinomial logit model (MNL). Our study confirmed pronounced spatial disparities in transportation accessibility to SIs, highlighting significantly lower access in rural and remote regions compared to urban centers and densely populated areas, consistent with existing literature. Building on prior findings, several additional findings were identified. First, we uncovered significant positive correlations among accessibility to different types of SIs in four critical categories: green and recreation spaces, health and aged care facilities, educational institutions, and justice and emergency services, revealing prevalent spatial inequality patterns. Second, we identified three distinct accessibility clusters (High, Middle, and Low) across the critical SI categories. Specifically, residents within the High cluster benefited from the closest average network distances to all SIs, while those in the Low cluster faced significant accessibility burdens (e.g., 22.9 km for welfare facilities, 20.1 km for hospitals, and 19.2 km for elderly care facilities). Third, MNL identified factors such as population density and housing prices as pivotal in spatial stratification of accessibility. Specifically, areas with lower SI accessibility tended to have a higher proportion of elderly residents. Also, decreased accessibility correlated with diminished traffic volumes across all transportation modes, particularly public transportation. This research contributes to enhancing our understanding of spatial inequalities in transportation accessibility to SIs and offers insights crucial for transportation and urban planning.

INTRODUCTION / OBJECTIVES: Studies have shown that Coronavirus Disease 2019 (COVID-19) is associated with a hypercoagulable state. Studies have yet to examine the interconnectedness between COVID-19, hypercoagulability, and socioeconomics. The aim of this work is to investigate socioeconomic factors that may be associated with pulmonary embolism (PE), Deep Vein Thrombosis (DVT), and COVID-19 in the United States (U.S.). METHODS: We performed a 1-year (2020) analysis of the National Inpatient Sample database. We identified all adult patients diagnosed with COVID-19, acute PE, or acute DVT using unweighted samples. We calculated the correlation and odds ratio (OR) between COVID-19 and 1) PE, and 2) DVT. We executed a univariate analysis followed by a multivariate analysis to examine the effect of different factors on PE and DVT during the COVID-19 pandemic. RESULTS: 322,319 patients were identified with COVID-19, while 78,101 and 67,826 patients were identified with PE and DVT, respectively. PE and DVT, as well as, inpatient mortality associated with both conditions are significantly correlated to COVID-19. The OR between COVID-19 and PE was 2.04, while the OR between COVID-19 and DVT was 1.44. Using multivariate analysis, COVID-19 was associated with a higher incidence of PE (coefficient 2.05) and DVT (coefficient 1.42). Other factors that were significantly associated (p<0.001) with increased incidence of PE and DVT along with their coefficients, respectively, include Black race (1.23, 1.14); top quartile income (1.08, 1.16); west region (1.10, 1.04); urban teaching facilities (1.09, 1.63); large bed size hospitals (1.08, 1.29); insufficient insurance (1.88, 2.19); hypertension (1.24, 1.32); and obesity (1.41, 1.25). Factors that were significantly associated (p<0.001) with decreased incidence of PE and DVT along with their coefficients, respectively, include Asians/Pacific Islanders (0.52, 0.53); female sex (0.79, 0.74); homelessness (0.62, 0.61); and diabetes mellitus (0.77, 0.90). CONCLUSION: In a nationwide inpatient sample of the United States, COVID-19 is positively correlated to venous thromboembolism - including its subtypes: pulmonary embolism and deep vein thrombosis. Utilizing multivariate analysis, Black race, male sex, top quartile income, west region, urban teaching facilities, large bed size hospitals, and insufficient social insurance were significantly associated with increased incidence of PE and DVT. Asians / Pacific Islanders, female sex, homelessness, and diabetes mellitus were significantly associated decreased incidence of PE and DVT.
ABSTRACT
BACKGROUND: Pelvic fractures can be life-threatening for elderly individuals with diminished bone strength. Frailty is associated with fracture outcomes, but its impact on pelvic fracture recovery remains unexplored. The aim of this study was to investigate the association between frailty and short-term outcomes in older adults hospitalized for low-energy pelvic fractures. METHODS: Data from the Nationwide Inpatient Sample (NIS) covering the years 2005 to 2018 were reviewed. Inclusion criteria were age ≥ 60 years admitted for a low-energy pelvic fracture. Patients were categorized into frail and non-frail groups using the 11-factor modified Frailty Index (mFI-11). Association between frailty and in-hospital outcomes were determined by univariate and multivariable regression analyses. RESULTS: A total of 24,688 patients with pelvic fractures were included. The mean patient age was 80.6 ± 0.1 years, and 35 % were classified as frail. After adjustments, frailty was significantly associated with unfavorable discharge (adjusted odds ratio [aOR] = 1.07, 95 % confidence interval [CI]: 1.00-1.15, p = 0.038), prolonged hospitalization (aOR = 1.51, 95 % CI: 1.41-1.62, p < 0.001), complications (aOR = 1.42, 95 % CI:1.34-1.50, p < 0.001), and acute kidney injury (aOR = 1.68, 95 % CI: 1.56-1.82, p < 0.001). Stratified analyses based on age and fracture type showed frailty was consistently associated with adverse outcomes. CONCLUSIONS: Persons ≥60 years old with mFI-11 assessed frailty and a low-energy pelvic fracture are at higher risk of adverse in-hospital outcomes than non-frail patients. Additional research is needed to disclose the prognostic impact of clinical frailty on long-term functional outcomes and quality of life after discharge.
ABSTRACT
OBJECTIVE: Pharyngeal foreign bodies (PFBs) are a prevalent disease affected by food culture and dietary habits, with fish bones as the leading cause. Most studies were limited to specific regions, and a nationwide survey was not conducted in Japan. In this ecological study, we aimed to conduct a nationwide analysis of outpatient PFB cases in Japan over three years, focusing on seasonal trends, sex- and age-stratified cases, and regional differences. METHODS: We used the National Database of Health Insurance Claims and Specific Health Checkups of Japan open data from April 2019 to March 2022. The case data were analyzed by month, age, sex, and prefecture. Additionally, we calculated the standardized claim ratios (SCRs) for each prefecture and investigated the association between dietary habits, food culture, and SCR of PFBs using a two-level linear regression model. RESULTS: We analyzed a total of 164,337 outpatient PFB cases in Japan, revealing an average incidence rate of 45.6 per 100,000 persons. The seasonal trend revealed a peak in July each year from 2019 to 2021, confirming seasonality in PFB incidents. Children reported a higher incidence rate. Living west of Japan and expenditure on fish and shellfish had a strongly positive association with the SCR of PFBs. CONCLUSION: Our nationwide survey reveals that, even within Japan, there were regional variations influenced by food culture and dietary habits. The data showed that PFB incidence was higher among children, highlighting the need for preventive education. LEVEL OF EVIDENCE: Level 3.
ABSTRACT
In the large-scale, prospective, observational JDCP study, a total of 5944 people with type 2 diabetes (mean age at baseline, 61.4 years old; women, 39.9%; and duration of diabetes, 10.8 years) were followed up for incidence of malignancy. During a mean 5.38 ± 2.92 years of follow-up, malignancies occurred in 322 individuals, accounting for a crude incidence of 10.35/1000 person-years. The 3 most frequently reported malignancies included colorectal cancers (20.4%), breast cancer (16.5%) and lung cancers (13.6%) in women, and gastric cancers (18.3%), colorectal cancers (15.7%) and lung/prostate cancers (12.7%) in men. During follow-up, men had a significantly higher relative risk for malignancy than women. In contrast, women had a significantly shorter time to the first diagnosis of malignancy following a diagnosis of diabetes than men (13.79 ± 7.90 and 17.11 ± 8.50 years, respectively), although there was no marked difference in the age at the diagnosis of malignancy (67.39 ± 7.27 and 68.44 ± 6.62 years, respectively). Cox proportional hazard models revealed that increasing age, a history of drinking and a history of acute myocardial infarction were significantly associated with an increased risk of malignancy. This report may be of interest in that it provides valuable insight into which malignancies Japanese people with type 2 diabetes are likely to be at risk of developing over time.
ABSTRACT
OBJECTIVES: Current guidelines provide limited evidence for cardiovascular screening in ANCA-associated vasculitis (AAV). This study aimed to investigate the prevalence of electrocardiogram (ECG) abnormalities and associations between no, minor or major ECG abnormalities with cardiovascular mortality in AAV patients compared with matched controls. METHOD: Using a risk-set matched cohort design, patients diagnosed with granulomatosis with polyangiitis or microscopic polyangiitis with digital ECGs were identified from Danish registers from 2000-2021. Patients were matched 1:3 to controls without AAV on age, sex, and year of ECG measurement. Associated hazards of cardiovascular mortality according to ECG abnormalities were assessed in Cox regression models adjusted for age, sex, and comorbidities, with subsequent computation of 5-year risk of cardiovascular mortality standardized to the age- and sex-distribution of the sample. RESULTS: A total of 1431 AAV patients were included (median age: 69 years, 52.3% male). Median follow-up was 4.8 years. AAV was associated with higher prevalence of left ventricular hypertrophy (17.5% vs 12.5%), ST-T deviations (10.1% vs 7.1%), atrial fibrillation (9.6% vs 7.5%), and QTc prolongation (5.9% vs 3.6%). Only AAV patients with major ECG abnormalities demonstrated significantly elevated risk of cardiovascular mortality [HR 1.99 (1.49-2.65)] compared with controls. This corresponded to a 5-year risk of cardiovascular mortality of 19.14% (16-22%) vs 9.41% (8-11%). CONCLUSION: Patients with AAV demonstrated a higher prevalence of major ECG abnormalities than controls. Notably, major ECG abnormalities were associated with a significantly increased risk of cardiovascular mortality. These results advocate for the inclusion of ECG assessment into routine clinical care for AAV patients.
ABSTRACT
Systemic lupus erythematosus (SLE) can adversely affect surgical outcomes, and the impact on revision total knee arthroplasty (TKA) outcomes is unclear. This study aimed to explore the impact of SLE on in-patient outcomes of revision TKA. The Nationwide Inpatient Sample (NIS) database from 2005 to 2018 was searched for patients aged ≥ 18 years old who received revision TKA. Patients with and without SLE were propensity score matched (PSM) at a 1:4 ratio. Associations between SLE and in-hospital outcomes were examined using regression analyses. The study included 133,054 patients, with 794 having SLE. After 1:4 PSM, data of 3,970 patients were analyzed (SLE, 794; non-SLE, 3,176). Multivariate-adjusted analyses revealed that SLE patients had a significantly higher risk of postoperative complications (adjusted odds ratio [aOR] = 1.23, 95% confidence interval [CI]: 1.05-1.44, p = 0.011), non-routine discharge (aOR = 1.22, 95% CI: 1.02-1.46, p = 0.028), major blood loss (aOR = 1.19), respiratory failure/mechanical ventilation (aOR = 1.79), acute kidney injury (AKI) (aOR = 1.47), and wound dehiscence (aOR = 2.09). SLE patients also had a longer length of hospital stay (aBeta = 0.31) and greater total hospital costs (aBeta = 6.35) compared to non-SLE patients. Among those with aseptic failure, SLE patients had a significantly higher risk of postoperative complications (aOR = 1.23) and non-routine discharge (aOR = 1.36). SLE is independently associated with worse in-hospital outcomes in patients undergoing revision TKA. This study highlights the importance of heightened vigilance and tailored perioperative management for patients undergoing major surgeries in the background of SLE. Key Points ⢠SLE significantly increases the risk of non-routine discharge, major blood loss, respiratory failure, acute kidney injury, and wound dehiscence, in patients undergoing aseptic and septic revision TKA. ⢠Patients with SLE experience longer hospital stays and higher hospital costs compared to those without SLE. ⢠The study's findings highlight the necessity for healthcare providers to consider the presence of SLE as a critical factor in preoperative planning and postoperative care to improve outcomes in revision TKA patients.
ABSTRACT
Background Irritable bowel syndrome (IBS) continues to pose significant healthcare challenges due to its broad differential diagnosis and the often extensive yet inconclusive workup. We investigated the rates and characteristics of unplanned 30-day readmissions in adult patients hospitalized with IBS. In addition, we identified factors that predict readmission within 30 days of initial discharge. Methods We analyzed the 2020 Nationwide Readmission Database. Using the International Classification of Diseases, Tenth Revision, Clinical Modification code, we identified hospitalizations in adult patients with IBS. We excluded hospitalizations for minors and planned or elective readmissions. To compare baseline characteristics between readmissions and index hospitalizations, χ2 tests were employed. We used multivariate Cox regression analyses to identify independent predictors of readmissions. Results A total of 5,729 adult hospitalizations with IBS as the primary diagnosis were discharged alive, and 638 (11.1%) readmissions occurred within 30 days. The most common diagnoses associated with readmission were noninfective gastroenteritis and colitis, sepsis, enterocolitis due to Clostridium difficile, and irritable bowel syndrome with or without diarrhea. Patients in readmissions had a mean age of 56.3 years, similar to index hospitalizations (54.5 years, p=0.093). Readmissions had a higher burden of comorbidity (Charlson comorbidity index (CMI) scores ≥3: 26.7%, 170 cases vs. 16.6%, 953 cases; p<0.001) and were mostly Medicare beneficiaries (49.5%, 316% vs. 44.9%, 2,578) compared with index hospitalizations. Readmissions had a longer mean length of stay (LOS) (5.2 vs. 3.6 days, p<0.0001), higher inpatient mortality (0.8%, 5% vs. 0.2%, 11; p=0.032), and higher mean hospital costs ($47,852 vs. $34,592; p<0.0001) compared with index admissions. Secondary diagnoses of ulcerative colitis (adjusted hazard ratio (AHR), 2.82; p<0.0001), interstitial cystitis (AHR, 5.37; p=0.007), peripheral vascular disease (AHR, 1.59; p=0.027), and discharge to short-term hospitals (AHR, 1.03; p<0.0001) were significantly associated with a higher likelihood of readmission within 30 days. Conclusion IBS readmissions have poorer outcomes than index hospitalizations. Patients with an existing history of ulcerative colitis, interstitial cystitis, and peripheral vascular disease and those discharged to short-term hospitals following index hospitalization are more likely to be readmitted within 30 days.
ABSTRACT
BACKGROUND: Failure-free survival (FFS) rates of low-risk patients with rhabdomyosarcoma improved in Intergroup Rhabdomyosarcoma Study IV after the escalation of cyclophosphamide total dose to 26.4 g/m2. However, this dose may increase the risk of adverse events, including infertility, in some patients. The JRS-I LRA0401 and LRB0402 protocols aimed to reduce the cyclophosphamide dose to 9.6 g/m2 and 17.6 g/m2, respectively, without decreasing the FFS rates. METHODS: Subgroup-A patients received eight cycles (24 weeks) of vincristine, actinomycin D, and 1.2 g/m2/cycle cyclophosphamide. Subgroup-B patients received eight cycles (24 weeks) of vincristine, actinomycin D, and 2.2 g/m2/cycle cyclophosphamide, followed by six cycles (24 weeks) of vincristine and actinomycin D. Group II/III patients in both subgroups received radiotherapy. RESULTS: In subgroup A (n = 12), the 3-year FFS rate was 83% (95% confidence interval [CI], 48-96), and the 3-year overall survival (OS) rate was 100%. Only one isolated local recurrence was observed (8.3%). There were no unexpected grade-4 toxicities and no deaths. In subgroup B (n = 16), the 3-year FFS and OS rates were 88% (95% CI, 59-97) and 94% (95% CI, 63-99), respectively. There were no unexpected grade 4 toxicities and no deaths. CONCLUSIONS: Shorter duration therapy using vincristine, actinomycin D, and lower dose cyclophosphamide with or without radiotherapy for patients with low-risk subgroup A rhabdomyosarcoma (JRS-I LRA0401 protocol) and moderate reduction of cyclophosphamide dose for patients with low-risk subgroup B rhabdomyosarcoma (JRS-I LRB0402 protocol) did not compromise FFS.
ABSTRACT
BACKGROUND: Ischemic heart disease (IHD) has been linked to an increased risk of atrial fibrillation (AF). However, data are sparse regarding the role of IHD in AF recurrence after catheter ablation. OBJECTIVE: To investigate whether preexisting or new-onset IHD is associated with a greater risk of AF recurrence after ablation. METHODS: Using Danish nationwide registries, all patients undergoing first-time AF ablation in Denmark from 2010 to 2020 were identified. The primary outcome was AF recurrence defined by AF-related hospital admission or antiarrhythmic drug use within 1 year after ablation excluding a 3-month blanking period. IHD was defined as an ICD-10 diagnosis of IHD and/or prior coronary revascularization. RESULTS: Among 12,162 patients undergoing first-time ablation for AF (mean age 62 years, 30% female), 20% had preexisting IHD. Preexisting IHD was associated with an increased risk of AF recurrence in univariable Log binomial logistic regression (relative risk (RR) 1.09, 95%CI 1.04-1-14, p<0.001). However, after multivariable adjustment including procedural year, preexisting IHD was no longer associated with an increased risk of AF recurrence (RR 1.02, 95%CI 0.97-1.06, p=0.42). In a nested case-control study among those without preexisting IHD prior to ablation (N=9,778), newly diagnosed IHD after ablation was associated with an increased risk of AF recurrence in multivariable analysis (hazard ratio 3.03, 95%CI 1.84-4.99, p<0.001). CONCLUSION: The presence of IHD does not appear to reduce the effectiveness of AF ablation procedures. However, the emergence of IHD after AF ablation may serve as a trigger for AF that is insufficiently suppressed by prior ablation.
ABSTRACT
Osteogenesis imperfecta (OI) is the most common inherited form of bone fragility and includes a heterogeneous group of genetic disorders that most commonly result from defects associated with type I collagen. Although genetic analyses have been developed, nationwide research on the incidence and associated fractures in OI is lacking. This study aimed to investigate the patterns of OI prevalence, incidence, fracture rate, etc. in South Korea using National Health Insurance Service (NHIS) claims data. We found 1596 patients newly diagnosed with OI between March 2002 and February 2020. We evaluated the incidence, prevalence, and history of fractures, fracture site, prescription of anti-osteoporosis drugs, etc. To compare medical costs, fracture rates, and scoliosis rates, we created a control group comprising patients without OI using 1:1 propensity score matching. The prevalence of OI increased slightly each year, with an annual incidence of 20.20 per 100,000 live births. Mean fracture frequency in OI patients was 17 (2-32) times per patient and the most frequent fracture site was the lower leg. A total of 21.4% patients were prescribed anti-osteoporosis drugs, and the most popular drug was pamidronate. After 1:1 propensity score matching, in terms of scoliosis, OI patients had a 3.91 times higher prevalence of scoliosis than in healthy patients which was statistically significant. The sum of medical care expenses for patients with OI was 3.5 times higher than that for patients without OI. We identified nationwide trends in OI occurrence, fractures, and medication use. This study also highlighted the real-world data of scoliosis and medical costs compared to the control group.
ABSTRACT
Objective: The objective of this study was to determine the implementation, clinical barriers, and unmet needs of repetitive transcranial magnetic stimulation (rTMS) and neuro-navigation systems for stroke rehabilitation. Design: We employed a nationwide survey via Google Forms (web and mobile) consisting of 36 questions across rTMS and neuro-navigation systems, focusing on their implementation, perceptions, and unmet needs in stroke recovery. The survey targeted physiatrists registered in the Korean Society for Neuro-rehabilitation and in rehabilitation hospitals in South Korea. Results: Of 1,129 surveys distributed, 122 responses were analyzed. Most respondents acknowledged the effectiveness of rTMS in treating post-stroke impairments; however, they highlighted significant unmet needs in standardized treatment protocols, guidelines, education, device usability, and insurance coverage. Unmet needs for neuro-navigation were also identified; only 7.4% of respondents currently used such systems, despite acknowledging their potential to enhance treatment accuracy. Seventy percent of respondents identified lack of prescription coverage, time and errors in preparation, and device cost as barriers to clinical adoption of neuro-navigation systems. Conclusion: Despite recognition of the potential of rTMS in stroke rehabilitation, there is a considerable gap between research evidence and clinical practice. Addressing these challenges, establishing standardized protocols, and advancing accessible neuro-navigation systems could significantly enhance the clinical application of rTMS, offering a more personalized, effective treatment modality for stroke recovery.
ABSTRACT
BACKGROUND: Dystrophic epidermolysis bullosa (DEB) describes a rare genetic blistering disorder characterized by fragile skin. This study aimed to classify the frequency, demographics, cost, and comorbidities associated with emergency department (ED) visits due to DEB. METHODS: The Nationwide Emergency Department Sample (NEDS) was analyzed for pediatric (age <18) ED visits from 2015 to 2019. DEB was identified with ICD-10-CM code Q81.2. Weighted frequency, prevalence, and 95% confidence intervals (CIs) of comorbidities were determined among ED visits with and without a DEB diagnosis. RESULTS: From 2015 to 2019, 53 (weighted 242) cases of DEB among 27,223,220 pediatric ED visits were captured. Patients with DEB were more likely to visit the ED in summer compared with those without a diagnosis of DEB (35.7% vs. 21.4%, P < .05). More than half of patients with DEB were admitted to the hospital (56.2%, 95% CI: 39.3-72.5, P < .001) versus only 3.4% (95% CI: 3.1-3.7) of other patients. For ED visits with a secondary DEB diagnosis, the top three primary diagnoses were fever, constipation, and bone marrow transplant aftercare. Patients with DEB had higher rates of hypertension, cellulitis, sepsis, acute and chronic kidney injury, esophageal obstruction, gastroesophageal reflux disease, cardiomyopathy, and anxiety, compared to patients without DEB (all P < .001). CONCLUSIONS: DEB is a complex blistering disorder with multisystemic manifestations. Patients with DEB have significantly higher admission rates and commonly present with infectious or gastrointestinal complications. Understanding the features of ED visits due to DEB can better prepare healthcare teams and improve patient outcomes.
ABSTRACT
BACKGROUND: Although alcohol-intoxicated patients have difficulties evaluating their consciousness level and being transported prehospital, there is some evidence that the survival outcomes for alcohol-intoxicated patients with head injuries are better. The present study evaluated whether the survival and brain function outcomes in alcohol-intoxicated trauma patients with head injuries were better than those in sober patients using the Japan Trauma Data Bank (JTDB), a nationwide trauma registry in Japan. METHODS: The 17,823 patients with blunt trauma, including head injuries, who were registered in the JTDB database between January 2019 and December 2021 were retrospectively analyzed. Logistic regression analyses were performed for in-hospital survival in patients with blunt trauma, including those with head injuries, and for good brain function based on the Glasgow outcome scale (GOS) in patients with only head injuries. Survival rates by head injury score using the abbreviated injury scale (AIS) 2008 or injury severity score (ISS) categories were compared between drinking and nondrinking groups. RESULTS: Drinking significantly affected survival (odds ratio 1.800, p<0.001) and good brain function (odds ratio 1.546, p<0.001), as indicated by logistic regression analysis using head injuries alone or blunt multisite trauma (including head injuries), respectively. According to analyses by the ISS category or head AIS score, there were significant differences between the drinking and non-drinking groups in several categories (ISS 9-15, 16-24, and 25-40 and AIS 3 and 5) regarding survival rates with blunt trauma, including head injuries, or good GOS rates with head injuries alone. CONCLUSIONS: The survival rates for blunt trauma, including head injuries, and the prognosis for brain function based on the GOS were better in the drinking group than in the control group for cases with head injuries alone. A multivariate analysis also showed that alcohol consumption was significantly associated with better outcomes.
ABSTRACT
Background: Identifying risk factors for early child physical abuse (CPA) is crucial for understanding its mechanisms and defining effective preventive interventions. We aimed to identify maternal, prenatal and postnatal factors associated with early CPA. Methods: This cohort study was based on comprehensive data from the Mother-Child EPI-MERES nationwide register and included all infants born alive in France between 2010 and 2019. Factors associated with early CPA (before age 1) were identified with a multilevel Cox regression model with random intercepts at the regional level. Findings: Among the 6,897,384 included infants, 2994 (40/100,000) had a diagnosis of early CPA, at a median age of 4 months. Independent factors most strongly associated with early CPA were maternal low financial resources (adjusted hazard ratio [aHR] 1.91; 95% confidence interval [95% CI] 1.67-2.18), maternal age <20 years versus 35-40 years (aHR 7.06; 95% CI 6.00-8.31), maternal alcohol use disorder (aHR 1.85; 95% CI 1.48-2.31), opioid use disorder (aHR 1.90; 95% CI 1.41-2.56), intimate partner violence (aHR 3.33; 95% CI 2.76-4.01), diagnosis of a chronic mental disorder (aHR 1.50; 95% CI 1.14-1.97) or somatic disorder (aHR 1.55; 95% CI 1.32-1.83), hospitalisation for a mental disorder (aHR 1.88; 95% CI 1.49-2.36), very preterm birth (aHR 2.15; 95% CI 1.68-2.75), and diagnosis of a chronic severe neurocognitive disorder in the infant (aHR 14.37; 95% CI 11.85-17.44). Interpretation: Independent risk factors of early CPA identified at the national level in France may help in understanding CPA mechanisms and developing effective prevention programs including risk-stratification tools to optimise the allocation of parenting interventions to parents who could most benefit from them.
