Carceral capitalism
What we see happening in Ferguson and other cities around the country is not the creation of livable spaces, but the creation of living hells. When people are trapped in a cycle of debt it also can affect their subjectivity and how they temporally inhabit the world by making it difficult for them to imagine and plan for the future. What psychic toll does this have on residents? How does it feel to be routinely dehumanized and exploited by the police? -- from Carceral CapitalismIn this collection of essays in Semiotext(e)'s Intervention series, Jackie Wang examines the contemporary incarceration techniques that have emerged since the 1990s. The essays illustrate various aspects of the carceral continuum, including the biopolitics of juvenile delinquency, predatory policing, the political economy of fees and fines, cybernetic governance, and algorithmic policing. Included in this volume is Wang's influential critique of liberal anti-racist politics, \"Against Innocence,\" as well as essays on RoboCop, techno-policing, and the aesthetic problem of making invisible forms of power legible.Wang shows that the new racial capitalism begins with parasitic governance and predatory lending that extends credit only to dispossess later. Predatory lending has a decidedly spatial character and exists in many forms, including subprime mortgage loans, student loans for sham for-profit colleges, car loans, rent-to-own scams, payday loans, and bail bond loans.

Spinal needles versus conventional needles for fine-needle aspiration biopsy of thyroid nodules—A multicenter randomized controlled trial
Ultrasound-guided fine-needle aspiration biopsy (FNAB) is essential for evaluating thyroid nodules but often yields inadequate samples, leading to repeated procedures, increased discomfort, and higher costs. Previous non-randomized studies found promising results of spinal needles to improve diagnostic adequacy. Therefore, we conducted a multicenter randomized controlled trial to validate these findings.
Between July 1st, 2021, and April 13th, 2023, patients with suspicious thyroid nodules were randomized to receive FNAB with either a 25G spinal needle or conventional needle. The primary outcome was the rate of adequate diagnostic cytology. Secondary outcomes included procedure-related pain, sensitivity and specificity of FNAB, and adverse events.
A total of 359 patients (75.6% female), with a mean age of 59.7 years (range 23-94) were randomized. The rate of adequate diagnostic FNAB was 86.2% (156/181) for the spinal group compared to 84.8% (151/178) for the control group (OR 1.01; 95% CI: 0.95-1.08). The mean pain scale score was 4.0 (SD = 1.8) in the spinal group and 3.9 (SD = 2.0) in the control group (p = 0.40). No complications were observed in either group. We found a significantly better cytological adequacy rate of FNABs performed by physicians with more than four years of experience in the procedure (OR=1.07; 95% CI, 1.01-1.14).
No significant improvement was found using spinal needles with a stylet compared to conventional needles. Given the significantly higher cost of spinal needles and comparable diagnostic outcomes, their routine use for thyroid FNAB is not recommended.

Repetitive seasonal drought causes substantial species-specific shifts in fine-root longevity and spatio-temporal production patterns in mature temperate forest trees
• Temperate forest ecosystems are exposed to a higher frequency, duration and severity of drought. To promote forest longevity in a changing climate, we require a better understanding of the long-term impacts of repetitive drought events on fine-root dynamics in mature forests.
• Using minirhizotron methods, we investigated the effect of seasonal drought on fine-root dynamics in single-species and mixed-species arrangements of Fagus sylvatica (European beech) and Picea abies (Norway spruce) by means of a 4-yr-long throughfall-exclusion experiment.
• Fine-root production of both species decreased under drought. However, this reduction was not evident for P. abies when grown intermixed with F. sylvatica. Throughfall-exclusion prolonged the lifespan of P. abies roots but did not change the lifespan of F. sylvatica roots, except in 2016. Fagus sylvatica responded to drought by reducing fine-root production at specific depths and during roof closure.
• This is the first study to examine long-term trends in mature forest fine-root dynamics under repetitive drought events. Species-specific fine-root responses to drought have implications for the rate and depth of root-derived organic matter supply to soil. From a root dynamics perspective, intermixing tree species is not beneficial to all species but dampens drought impacts on the belowground productivity of P. abies.

Diagnostic Yield and Safety of the 19-Gauge versus 22-Gauge Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration Needle in Subjects with Sarcoidosis (GUESS)
Abstract
Introduction: Observational data suggest that the 19-gauge (G) needle for endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) offers a higher diagnostic yield than the 22-G needle in sarcoidosis. No randomized trial has compared the yield of the two needles. Methods: We randomized consecutive subjects with suspected sarcoidosis and enlarged thoracic lymph nodes to undergo EBUS-TBNA with either the 19-G or the 22-G needle. We compared the study groups for diagnostic sensitivity (primary outcome) assessed by the yield of granulomas in subjects finally diagnosed with sarcoidosis. We also compared the sample adequacy, difficulty performing the needle puncture assessed on a visual analog scale (VAS), the subject’s cough intensity on an operator-rated VAS, and procedure-related complications (secondary outcomes). Results: We randomized 150 (mean age, 43.0 years; 55% women) subjects and diagnosed sarcoidosis in 116 subjects. The diagnostic sensitivity of the 19-G needle (45/60, 75.0%) was not higher (p = 0.52) than the 22-G needle (39/56, 69.6%). We obtained adequate aspirates in 90.0% and 85.7% of subjects in the respective groups (p = 0.48). The operators had greater difficulty puncturing lymph nodes with the 19-G needle (p = 0.03), while the operator-assessed cough intensity was similar in the groups (p = 0.41). Transient hypoxemia was the only complication encountered during EBUS-TBNA (two subjects in either group). Conclusion: We did not find the 19-G needle superior to the 22-G in diagnostic sensitivity, specimen adequacy, or safety of EBUS-TBNA in sarcoidosis. Puncturing the lymph nodes was more difficult with the 19-G needle.

Criminalizing Poverty
Court-related fines and fees are widely levied on criminal defendants who are frequently poor and have little capacity to pay. Such financial obligations may produce a criminalization of poverty, where later court involvement results not from crime but from an inability to meet the financial burdens of the legal process. We test this hypothesis using a randomized controlled trial of court-related fee relief for misdemeanor defendants in Oklahoma County, Oklahoma. We find that relief from fees does not affect new criminal charges, convictions, or jail bookings after 12 months. However, control respondents were subject to debt collection efforts at significantly higher rates that involved new warrants, additional court debt, tax refund garnishment, and referral to a private debt collector. Despite significant efforts at debt collection among those in the control group, payments to the court totaled less than 5 percent of outstanding debt. The evidence indicates that court debt charged to indigent defendants neither caused nor deterred new crime, and the government obtained little financial benefit. Yet, fines and fees contributed to a criminalization of low-income defendants, placing them at risk of ongoing court involvement through new warrants and debt collection.

The Clinical Impact of Immediate On-Site Cytopathology Evaluation During Endoscopic Ultrasound-Guided Fine Needle Aspiration of Pancreatic Masses: A Prospective Multicenter Randomized Controlled Trial
Observational data on the impact of on-site cytopathology evaluation (OCE) during endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) of pancreatic masses have reported conflicting results. We aimed to compare the diagnostic yield of malignancy and proportion of inadequate specimens between patients undergoing EUS-FNA of pancreatic masses with and without OCE.
In this multicenter randomized controlled trial, consecutive patients with solid pancreatic mass underwent randomization for EUS-FNA with or without OCE. The number of FNA passes in the OCE+ arm was dictated by the on-site cytopathologist, whereas seven passes were performed in OCE- arm. EUS-FNA protocol was standardized, and slides were reviewed by cytopathologists using standardized criteria for cytologic characteristics and diagnosis.
A total of 241 patients (121 OCE+, 120 OCE-) were included. There was no difference between the two groups in diagnostic yield of malignancy (OCE+ 75.2% vs. OCE- 71.6%, P=0.45) and proportion of inadequate specimens (9.8 vs. 13.3%, P=0.31). Procedures in OCE+ group required fewer EUS-FNA passes (median, OCE+ 4 vs. OCE- 7, P<0.0001). There was no significant difference between the two groups with regard to overall procedure time, adverse events, number of repeat procedures, costs (based on baseline cost-minimization analysis), and accuracy (using predefined criteria for final diagnosis of malignancy). There was no difference between the two groups with respect to cytologic characteristics of cellularity, bloodiness, number of cells/slide, and contamination.
Results of this study demonstrated no significant difference in the diagnostic yield of malignancy, proportion of inadequate specimens, and accuracy in patients with pancreatic mass undergoing EUS-FNA with or without OCE.

Atributos de los medios de comunicación y cambio de actitud: experimentos sobre el impacto del establecimiento de la agenda de segundo nivel sobre las actitudes hacia los refugiados sirios
Esta investigación examina cómo el contenido de las noticias influye en las actitudes hacia los refugiados sirios en Turquía. El objetivo del estudio es comprender el modo de atribución de los refugiados sirios por los medios de comunicación, es decir, la conformación de su imagen. Más específicamente, pretendemos determinar si la cobertura de noticias positivas sobre los refugiados sirios causaría un cambio de actitud en el público de negativo a positivo. Para los fines del estudio, hemos realizado una investigación cuasi-experimental y se utilizó un diseño de prueba previa para investigar los efectos de establecimiento de la agenda de segundo nivel. Dos experimentos (un piloto y un experimento principal) se realizaron durante el trimestre de primavera de 2017 en Turquía. Los participantes para los experimentos fueron seleccionados en una gran universidad privada de Turquía. Los resultados de la prueba sugieren que el énfasis positivo de los medios en las imágenes de los refugiados sirios tuvo un impacto positivo en la opinión pública y causó un cambio general de actitud en el público.

Redefining fine roots improves understanding of below-ground contributions to terrestrial biosphere processes
Fine roots acquire essential soil resources and mediate biogeochemical cycling in terrestrial ecosystems. Estimates of carbon and nutrient allocation to build and maintain these structures remain uncertain because of the challenges of consistently measuring and interpreting fine-root systems. Traditionally, fine roots have been defined as all roots ≤ 2 mm in diameter, yet it is now recognized that this approach fails to capture the diversity of form and function observed among fine-root orders. Here, we demonstrate how order-based and functional classification frameworks improve our understanding of dynamic root processes in ecosystems dominated by perennial plants. In these frameworks, fine roots are either separated into individual root orders or functionally defined into a shorter-lived absorptive pool and a longer-lived transport fine-root pool. Using these frameworks, we estimate that fine-root production and turnover represent 22% of terrestrial net primary production globally – a c. 30% reduction from previous estimates assuming a single fine-root pool. Future work developing tools to rapidly differentiate functional fine-root classes, explicit incorporation of mycorrhizal fungi into fine-root studies, and wider adoption of a two-pool approach to model fine roots provide opportunities to better understand below-ground processes in the terrestrial biosphere.

High clinical impact and diagnostic accuracy of EUS-guided biopsy sampling of subepithelial lesions: a prospective, comparative study
BackgroundIn a tertiary center setting we aimed to study the diagnostic accuracy and clinical impact of EUS-guided biopsy sampling (EUS-FNB) with a reverse bevel needle compared with that of fine needle aspiration (EUS-FNA) in the work-up of subepithelial lesions (SEL).MethodsAll patients presenting with SELs referred for EUS-guided sampling were prospectively included in 2012–2015. After randomization of the first pass modality, dual sampling with both EUS-FNB and EUS-FNA was performed in each lesion. Outcome measures in an intention-to-diagnose analysis were the diagnostic accuracy, technical failures, and adverse events. The clinical impact was measured as the performance of additional diagnostic procedures post-EUS and the rate of unwarranted resections compared with a reference cohort of SELs sampled in the same institution 2006–2011.ResultsIn 70 dual sampling procedures of unique lesions (size: 6–220 mm) the diagnostic sensitivity for malignancy and the overall accuracy of EUS-FNB was superior to EUS-FNA compared head-to-head (90 vs 52%, and 83 vs 49%, both p < 0.001). The adverse event rate of EUS-FNB was low (1.2%). EUS-FNB in 2012–2015 had a positive clinical impact in comparison with the reference cohort demonstrated by less cases referred for an additional diagnostic procedure, 12/83 (14%) vs 39/73 (53%), p < 0.001, and fewer unwarranted resections in cases subjected to surgery, 3/48 (6%) vs 12/35 (34%), p = 0.001.ConclusionsEUS-FNB with a reverse bevel needle is safe and superior to EUS-FNA in providing a conclusive diagnosis of subepithelial lesions. This biopsy sampling approach facilitates a rational clinical management and accurate treatment.
