ABSTRACT

IMPORTANCE: A major portion of adolescents and adults seeking psychiatric treatment report nonsuicidal self-injury (NSSI) within the past month, yet the short-term course of NSSI among these patients remains poorly understood.

OBJECTIVE: To advance the understanding of the short-term course of NSSI cognitions (ie, thoughts, urges, and self-efficacy to resist self-injury) and behavior.

DESIGN, SETTING, AND PARTICIPANTS: A cohort study was conducted using an intensive longitudinal design with ecological momentary assessment, including 6 daily surveys and event registrations of self-injury for 28 days. Data were collected from June 2021 to August 2023. Individuals using mental health services in the Flanders region in Belgium reporting past-month NSSI urges and/or behavior at intake were recruited by referral.

MAIN OUTCOMES AND MEASURES: Nonsuicidal self-injury thoughts, urges, self-efficacy, and behavior. Sociodemographic and clinical baseline characteristics served as between-person variables. Descriptive and variability statistics and dynamic structural equation modeling were used.

RESULTS: Participants completed a mean (SD) of 121 (34.5) surveys, totaling 15 098 longitudinal assessments (median adherence, 78.6%; IQR, 59.5%-88.7%). Among 125 patients (87.2% female; median age, 22.0 [range, 15-39] years; 52.8% heterosexual), NSSI thoughts and urges were present during most assessments but were low in intensity (individual means [SD] on a 0- to 6-point scale, 1.52 [1.13] for urges; 1.57 [1.18] for thoughts). The prevalence of NSSI behavior was 84.0% monthly, 49.90% weekly, and 18.19% daily. Between-patient variability was substantial (intraclass correlation coefficient, 0.43-0.47; range of individual means for cognitions, 0-6; individual frequency behavior, 0-103), with recency and frequency of NSSI thoughts and behavior at intake consistently associated with individual differences in the course of NSSI. The greatest variability was observed within patients (root mean square of successive differences from 1.31 for self-efficacy to 1.40 for instability of thoughts), characterized by changes in the intensity of cognitions by more than 1 within-person SD between assessments less than 2 hours apart in 1 of 5 instances. Nonsuicidal self-injury behavior is rare in the morning, increased in the afternoon, and most frequent in the evening. Nonsuicidal self-injury cognitions were contemporaneous and temporally associated with each other’s course, with higher-than-usual thoughts and lower self-efficacy uniquely signaling heightened risk for NSSI behavior in the next 2 hours.

CONCLUSIONS AND RELEVANCE: In this cohort study of treatment-seeking individuals, NSSI cognitions and behavior appeared to be dynamic over the short term. These findings suggest the potential utility of self-monitoring outside the therapy setting and the need to focus assessment and interventions on the evening hours.

ABSTRACT

OBJECTIVE: To determine the diagnostic test accuracy of multiparametric magnetic resonance imaging (mpMRI) in detecting seminal vesicle invasion (SVI).

METHODS: The Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed, the Excerpta Medica dataBASE (EMBASE) and Cochrane databases were search up to May 2023. We included studies that investigated the accuracy of mpMRI in detecting SVI when compared to radical prostatectomy specimens as the reference standard. Data extraction was performed by two independent reviewers to construct 2 × 2 tables, as well as patient and study characteristics. The methodological quality of the included studies was assessed with the Quality of Assessment of Diagnostic Accuracy Studies-2 tool. Sensitivity and specificity were pooled and presented graphically with summary receiver operator characteristic (SROC) plots.

RESULTS: A total of 27 articles with 4862 patients were included for analysis. The summary sensitivity and specificity were 0.57 (95% confidence interval [CI] 0.45-0.68) and 0.95 (95% CI 0.92-0.99), respectively. Meta-regression indicated that there was no evidence that coil strength (P = 0.079), coil type (P = 0.589), year of publication (P = 0.503) or use of the Prostate Imaging-Reporting and Data System (P = 0.873) significantly influenced these results. The summary diagnostic odds ratio was 28.3 (95% CI 15.0-48.8) and the area under the curve for the SROC curve was 0.87. The I² statistic was a modest 11.9%. In general, methodological quality was good.

CONCLUSION: The use of mpMRI in detecting SVI has excellent specificity but poor sensitivity. Both endorectal coils and magnetic field strength do not significantly impact the accuracy of MRI. These findings suggest that mpMRI cannot reliably rule out SVI in patients with prostate cancer.

ABSTRACT

BACKGROUND: A national guideline on peripheral arterial disease management in England was issued in August 2012. The impact on revascularization rates was examined and variation with socioeconomic deprivation assessed.

METHODS: Annual hospital admissions for England over 10 years (2008-2009 to 2017-2018) were examined using interrupted time series analysis. A pragmatic approach was used to classify admissions for revascularization into moderate and severe categories.

RESULTS: There were 309 839 admissions (56% for moderate peripheral arterial disease), with an overall annual admission rate for revascularization of 86 per 100 000 population aged 25+ years. The rate for moderate peripheral arterial disease marginally increased by 0.29 per 100 000 per year (95% c.i. -0.22 to 0.80) from 2008-2009 to 2012-2013. Following guideline introduction, this rate decreased. The equivalent for severe peripheral arterial disease increased by 1.33 per 100 000 (0.78 to 1.88). Following guideline introduction, this rate plateaued. The change in rate (slope) for moderate peripheral arterial disease of -2.81 per 100 000 per year (-3.52 to -2.10) after guideline introduction was greater than the change in rate for severe peripheral arterial disease of -1.95 per 100 000 per year (-2.73 to -1.17). For moderate peripheral arterial disease, the annual rate in the most socioeconomically deprived category was 15.6 per 100 000 lower in 2017-2018 compared with 2012-2013 (24.3% decrease). The impact progressively diminished with decreasing deprivation. In the least deprived category, the reduction was 5.2 per 100 000 (12.9% decrease). For severe peripheral arterial disease, the decrease was 1.2 per 100 000 (3.1% reduction) with no consistent variation in relation to deprivation.

CONCLUSION: Introduction of the national peripheral arterial disease management guideline in England was associated with a reduction in admission rates for revascularization, especially for moderate peripheral arterial disease, with greater reduction in rates for moderate peripheral arterial disease in more socioeconomically deprived areas. Association, however, does not necessarily imply causation and alternative explanations cannot be ruled out.

ABSTRACT

OBJECTIVE: This study, derived from the phase 3 SAFE trial (ClinicalTrials.gov identifier: NCT2236806), explores subclinical cardiac damage in breast cancer patients receiving anthracycline-based chemotherapy and left-sided breast radiation therapy (RT).

MATERIALS AND METHODS: Eligible patients were randomized to a cardioprotective pharmacological therapy (bisoprolol, ramipril, or both) or placebo, with cardiac surveillance at multiple time-point using standard and 3-dimensional echocardiography. Dosimetric parameters were analysed, including mean heart dose (MHD) and various metrics for heart substructures, employing advanced contouring techniques and auto-contouring software.

RESULTS: In the analysis of left-sided breast RT patients, the study encompassed 39 out of 46 irradiated individuals, focusing on GLS and 3D-LVEF outcomes with ≥ 10% worsening, defined as subclinical heart damage. Distinct RT schedules were used, with placebo exhibiting the highest ≥ 10% worsening (36.4%). In terms of treatment arms, bisoprolol exhibited 11.1% worsening, while ramipril 16.7% and bisoprolol + ramipril 25%. For patients with no subclinical damage, the mean MHD was 1.5 Gy; for patients with subclinical heart damage, the mean MHD was 1.6 Gy (p = 0.94). Dosimetric parameters related to heart and heart substructures (left anterior descending artery, right and left atrium, right and left ventricle) showed no statistically significant differences between patients with and without subclinical damage.

CONCLUSION: Our results emphasize the crucial role of cardioprotective measures in mitigating adverse effects, highlighting RT as having negligible influence on cardiac performance. An extended follow-up assessment of the whole series is warranted to determine whether a subclinical effect could significantly influence clinical outcomes and cardiac events.

ABSTRACT

Microplastics (MPs) and heavy metal pollution pose significant environmental threat, potentially leading to agroecosystem toxicity and jeopardizing food security. Therefore, this study aims to evaluate the abundance and risk assessment of these pollutants in five different farmlands of Ernakulam district, India. Results showed that MPs content in agricultural fields near commercialized areas such as Kakkanad Nedungapuzha, Nedumbassery, and Kadamakuddy was dominant compared to Nechoor, a rural area. The average microplastic abundance was found to be 45.6 ± 26.4 items kg⁻¹ dw. Polypropylene (PP) and polyethylene (PE) were the dominant polymers found in the soil samples, constituting 45% and 25% of the microplastic content, respectively. The pollution load index of MPs indicates that the sampling sites are considered to be polluted as PLI > 1 with hazard level I. The heavy metal pollution status follows the order: Cu (80.3 to 724 mg/kg) > Zn (77 to 543.5 mg/kg) > Cr (171.65 to 334.65 mg/kg) > As (10.25 to 79.5 mg/kg) > Pb (2.05 to 30.3 mg/kg) > Cd (0.3 to 14.35 mg/kg). Calculated pollution load index (PLI) geo-accumulation index (Igeo), ecological risk assessment values indicate that commercialized regions exhibit high levels of trace metals, namely Cu, Zn, As, Cd, and Cr, posing a significant concern for the agricultural ecosystem. Our results indicate heightened microplastics and heavy metals prevalence in farmlands adjacent to commercial zones, necessitating immediate preventive action to mitigate increasing concentrations.

ABSTRACT

BACKGROUND AND OBJECTIVE: Intramedullary mature teratomas in adults are rare tumors that pose significant diagnostic and therapeutic challenges due to their diverse tissue composition and intramedullary location. This review, which includes an illustrative case, aims to provide a comprehensive overview of the clinical presentation, diagnosis, treatment, and outcomes of adult intramedullary mature teratomas through a systematic review of 89 cases.

METHODS: A systematic review was conducted following PRISMA guidelines, using keyword combinations in PubMed, MEDLINE, and Web of Science databases until June 2024. Inclusion criteria were adult patients (> 18 years) with histopathologically confirmed intramedullary mature teratomas. Statistical analyses examined relationships between the extent of resection (EoR), tumor location, and patient outcomes.

RESULTS: Among the 89 cases, the mean age was 39.94 ± 13.52 years, with a male-to-female ratio of 1.39:1. Tumors were most commonly located in the conus region (51.2%). Surgical resection was the primary treatment, with 43 cases undergoing partial resection and 33 gross total resection. No statistically significant differences in outcomes were found between EoR, sex, associated anomalies, or specific outcomes. However, younger patients showed improved outcomes for lower limb weakness and sphincter dysfunction. Recurrence was noted in three cases, all located in the conus.

CONCLUSION: Intramedullary mature teratomas require a nuanced approach that balances complete resection and neurological preservation. Early diagnosis and individualized surgical planning are crucial for optimizing outcomes. Despite the challenges, effective management is achievable, and ongoing research is essential to refining treatment strategies for this rare tumor.

ABSTRACT

OBJECTIVE: To evaluate the safety and efficacy of bridging intravenous thrombolysis plus mechanical thrombectomy (MT) versus direct MT in different age groups of patients with acute ischemic stroke (AIS) secondary to large vessel occlusion (LVO) of the anterior circulation.

METHODS: Consecutive patients from the prospective endovascular stroke registry of the Comprehensive Stroke Center, University of Rome Tor Vergata, Italy, between January 2015 and June 2021 were retrospectively analyzed. Patients were divided into age groups (≤ 80 years old and > 80 years old); for each age group, they were further divided in the bridging therapy group and the direct MT group. We performed a propensity score analysis according to baseline characteristics. Safety outcomes were any intracerebral hemorrhage (ICH), symptomatic ICH (sICH) and 3-month mortality. Efficacy outcomes were successful recanalization (modified Thrombolysis in Cerebral Infarction, mTICI, score ≥ 2b) and 3-month functional independence (modified Rankin Scale, mRS, ≤ 2).

RESULTS: We included 761 AIS patients with anterior circulation LVO (mean age 73.5 ± 12.8 years; 44.8% males; mean baseline NIHSS 16 ± 5). After propensity score, there were 365 patients ≤ 80 years old (52% bridging therapy) and 187 patients > 80 years old (57% bridging therapy). In both age groups of patients, we found no statistically significant differences in the rates of any ICH, sICH, successful recanalization and 3-month mortality and functional independence between bridging therapy and direct MT groups.

CONCLUSION: In our population, safety and efficacy outcomes of bridging therapy versus direct MT did not differ in both AIS patients ≤ 80 and > 80 years old.

ABSTRACT

PURPOSE: This PRISMA-guided and PROSPERO-registered systematic review aimed to summarise the current knowledge on the characteristics (clinical, radiographic, and histopathological) and treatment options for segmental odontomaxillary dysplasia (SOD).

METHODS: Descriptive studies, case series, and case reports were searched up to May 2024 in PubMed, Embase, Web of Science, SciELO, and the Cochrane Library databases. Statistical association analyses were performed on clinical variables, using chi-square tests.

RESULTS: The 35 included studies detailed 60 SOD cases in patients with a mean age of 12 ± 9.6 years. 11. Males were more frequently affected than females (62% or 1.6:1 ratio). Most cases involved the right maxilla (55%) and presented facial asymmetry and/or unilateral swelling (78%). Three cases involved both maxillae and mandible; Skin alterations were reported in 50% of the cases. Intraoral alterations such as alveolar process enlargement and gingival hyperplasia were also frequently observed (84% and 58%, respectively). All patients presented tooth alterations and 1st and/or 2nd upper premolars were absent in 80% of the cases. Dense bone and altered trabecular patterns were frequently observed in radiographs. Histopathological exams commonly showed dense trabecular bone and hyperplasic gingival tissue. Only 33 cases reported the SOD treatment, which ranged from follow-up without intervention up to surgery and orthodontics. No significant associations were found between sex and facial asymmetry or continuous lesion growth (p > 0.05). Additionally, no associations were found between intraoral alterations or symptoms and continuous lesion growth (p > 0.05).

CONCLUSION: This review presents SOD epidemiological, clinical, radiographic and histopathological data. Evidence regarding treatment is scarce.

ABSTRACT

BACKGROUND: The purpose of this study is to compare the clinical results of Left Atrial Appendage Closure (LAAC) and oral anticoagulation (OAC) in individuals with AF.

METHODS: For randomized controlled trials (RCTs) comparing the clinical results of OAC to LAAC in patients with atrial fibrillation (AF), we searched PubMed, ScienceDirect, and Cochrane. The included publications were subjected to meta-analyses using Review Manager v5.4.

RESULTS: In comparison to OAC, LAAC was linked with a decreased incidence of all stroke (OR 0.68; 95% CI 0.55-0.84; p = 0.0004). LAAC was also linked to a decreased risk of hemorrhagic stroke (OR 0.20, 95% CI 0.07-0.55; p = 0.002). There is no statistically significant difference between the two groups in terms of ischemic stroke (OR 1.05; 95% CI 0.59-1.84; p = 0.88) or systemic embolization (OR 1.02; 95% CI 0.42-2.46; p = 0.97).

CONCLUSIONS: According to our meta-analysis, the LAAC was less likely than the OAC to have a complete or hemorrhagic stroke. For the two groups, however, there was no difference in the risk of ischemic stroke or systemic embolization.

ABSTRACT

Flow-diverter devices (FDs) are effective in treating intracranial aneurysms (IAs) but carry substantial periprocedural risks, particularly ischemic complications. This study aimed to determine if elevated Systemic Immune-Inflammation Index (SII) can independently predict these risks and assess the impact of age and dual antiplatelet therapy on this association. We conducted a retrospective analysis of patients treated with FDs between February 2016 and August 2023, using blood samples taken within six days before surgery to calculate SII. Logistic regression and decision tree analyses assessed the link between SII and periprocedural complications, with subgroups exploring influencing factors. Multivariable analysis identified high SII as an independent predictor of periprocedural complications (OR = 5.306, 95% CI: 1.367-18.455; P = 0.009). The decision tree model confirmed SII > 0.437 as a critical threshold. Subgroup analysis showed a pronounced association of SII with periprocedural complications in patients ≥ 65 years (OR = 36.979, 95% CI: 2.103-650.134; P = 0.014) and in those on clopidogrel plus aspirin therapy (OR = 16.921, 95% CI: 2.733-104.746; P = 0.002). An elevated Systemic Immune-Inflammation Index (SII) > 0.437 significantly correlates with increased periprocedural complications (6.5% vs. 1.8%, P = 0.017). Although not statistically significant, higher SII is associated with a greater rate of ischemic events (3.9% vs. 0.9%). Elevated preoperative SII independently predicts periprocedural complications, particularly ischemic events, in patients undergoing FDs treatment for intracranial aneurysms. This association is particularly pronounced in older patients (> 65 years) and those receiving dual therapy with clopidogrel plus aspirin. Trial Registration: ClinicalTrials.gov (NCT06446778). Registered on May 22, 2024.
