The Age of Transition: Postdevelopment and North-South Synergies
Authors: Nourani Rinaldi Parisa 
Published: November 2021

The development enterprise has deepened the maladaptation of a social order built on the values of modernity and coloniality. Postcolonial scholars critiqued the discourses that were perpetuating its failures. Latin American decolonial scholars sharpened the analysis, rejecting Eurocentric frames of thought and drawing on a plurality of voices and ways of knowing. Mounting evidence of global socio-ecological interdependence has led to the emergence of discourses of transition advocating a break with the civilizational model of the modern West. Buen vivir and postextractivism are two Latin American examples of these discourses. Although there are divergences between these and Northern transition discourses, the scale of civilizational transition renders dialogue imperative. A review of the path of Latin American critical thought raises the possibility of North-South synergies, highlighting the implications of a true dialogue of ways of knowing. El proyecto del desarrollo ha profundizado la mala adaptación de un orden social construido sobre los valores de la modernidad y la colonialidad. Los analistas poscoloniales hicieron una crítica de los discursos que perpetuaban dichos fracasos. Los académicos descoloniales latinoamericanos fueron más allá, rechazando marcos de pensamiento eurocéntricos y recurriendo a una pluralidad de voces y formas de saber. La creciente evidencia en torno a la interdependencia socioecológica global ha llevado a la aparición de discursos de transición que abogan por una ruptura con el modelo civilizatorio del Occidente moderno. El buen vivir y el posextractivismo son dos ejemplos latinoamericanos de estos discursos. Aunque hay divergencias entre ellos y los discursos de transición del Norte, la escala de la transición civilizatoria exige el diálogo. Una revisión de la línea de pensamiento crítico latinoamericano plantea la posibilidad de sinergias Norte-Sur, destacando las implicaciones de un verdadero diálogo de saberes.
The Pattern of Capital Reproduction in Dependent and Financialized Capitalism

Published: November 2021

Financialization is the result of the development of social forces and relations of production translated into legal and institutional changes including the increasing importance of the financial sphere of capital and international financial circuits compared with the rest of the economy. An analysis from a lower level of abstraction, as proposed by the Marxist theory of dependency and Jaime Osorio’s work on the pattern of capital reproduction, must consider the differentiated incorporation of the periphery into financialized capitalism and its effects. A proposal that encompasses the cycles of capital and its reproduction in specific geo-historical contexts and establishes a dialogue between the pattern of capital reproduction and the changes in contemporary capitalism serves to extend Osorio’s ideas, including the identification of financialization as a new coil of the spiral of dependency. A financeirização é o resultado do desenvolvimento das forças sociais e das relações de produção traduzidas em mudanças jurídicas e institucionais, incluindo a crescente importância da esfera financeira do capital e dos circuitos financeiros internacionais em comparação com o resto da economia. Uma análise de um nível inferior de abstração, como proposto pela teoria marxista da dependência e o trabalho de Jaime Osorio sobre o padrão de reprodução do capital, deve considerar a incorporação diferenciada da periferia no capitalismo financeirizado e seus efeitos. Uma proposta que englobe os ciclos do capital e sua reprodução em contextos geo-históricos específicos e que estabeleça um diálogo entre o padrão de reprodução do capital e as mudanças no capitalismo contemporâneo serve para estender as ideias de Osório, incluindo a identificação da financeirização como uma nova bobina do espiral de dependência.

Published: November 2021

Background: Fibrovascular polyps (FVPs) with hypopharyngeal pedicles (hFVPs) are the rare intraluminal benign tumours of the upper aerodigestive tract, and their accurate diagnosis and optimal management are challenging. Purpose: The present retrospective study attempted to explore the optimal diagnosis and treatment of hFVPs. Research Design: The clinical records of 2 patients with giant, irregularly shaped hFVPs, who underwent several failed surgical procedures after inaccurate diagnosis, were reviewed. Finally, the patients were correctly diagnosed and successfully treated at Capital Medical University Beijing Friendship Hospital in different years, 2018 and 2020. Results: Case 1 was of a 43-year-old woman with 2 months of progressive dysphagia. Gastroenterologists overlooked the origin of her FVP, and decided to sever its narrowest point in the oesophagus through endoscopy. However, upon unsuccessful removal of the mass, a gastrotomy procedure was performed to extract the mass 7 days later. Symptoms recurred 3 months after the treatment, and a fibreoptic laryngoscopy confirmed hFVP in the patient at our department. A transcervical approach was used to sever the hypopharyngeal pedicle, achieve haemostasis and remove the oesophageal tumour. No recurrence was detected during the 2-year follow-up period after the treatment. Case 2 was of a 32-year-old man with dysphagia who had previously undergone transthoracic and transcervical oesophagotomy procedures within a gap of 3 months for the removal of FVP causing dysphagia. The hypopharyngeal pedicle was not diagnosed in the patient. The symptoms of dysphagia recurred 4 years after the treatment, and a fibreoptic laryngoscope confirmed hFVP at our department. The tumour was removed successfully through the transcervical approach. No recurrence was detected during the 6-months follow-up after surgery. Conclusion: In conclusion, the transcervical approach is suitable for achieving haemostasis and removing giant, irregularly shaped hFVPs.

Published: November 2021

Background Several disorders may result in forefoot pain. An uncommon cause of forefoot pain is subcutaneous plantar veins thrombosis (SCPVT) involving veins superficial to the plantar fascia. Purpose To describe the ultrasound (US) appearance of SCPVT, which has been described only once in the radiological literature. Material and Methods We performed a retrospective search of our PACS system from 2016 to 2020 to collect all cases of US-diagnosed SCPVT. We collected data on seven patients. Two radiologists analyzed the US images retrieved. All US examinations were performed with a multifrequency linear probe (frequencies in the range of 5–17 MHz). Results A localized plantar nodule was palpable in 86% of patients. The subcutaneous thrombosed vein appeared in all patients as a round or ovoid nodule located in the subcutaneous tissues that corresponded in four patients (4/5, 80%) to the painful palpable nodule. The size was in the range of 4–7 mm (mean = 5.4 mm). The thrombosed vein presented a connection with adjacent patent veins, appeared enlarged, and almost filled with hypo-isoechoic material, and in two patients (2/7, 29%), a thin peripheral fluid component surrounding the thrombus was detectable. Continuous scanning demonstrated slow blood movements inside the peripheral component due to blood circulation. Failure to compress the lumen of the thrombosed vein during the real-time US was evident in all patients. Conclusion SCPVT is a rare or underreported condition. Sonologists must know the US appearance of SCPVT to exclude other conditions and avoid unnecessary invasive studies.

Published: November 2021

Background Adnexal masses (AM) are a common gynecological problem. It is important to use a reliable imaging method in the differentiation of benign and malignant AMs. Purpose To assess the accuracy and validity of the O-RADS magnetic resonance imaging (MRI) score for characterizing AM using a simplified MRI protocol. Material and Methods The study population comprised 332 women who underwent MRI due to the detection of indeterminate AM on ultrasonography between January 2018 and June 2020. An experienced radiologist calculated the O-RADS MRI score into five categories, using an MRI protocol with a simplified dynamic study. Sensitivity, specificity, positive and negative predictive values, and area under the curve (AUC) were calculated (cutoff for malignancy, score ≥ 4). The reference standard was histopathologic diagnosis or imaging findings during >24 months of follow-up. Results Of 237 AMs, 28 (11.9%) were malignant. The malignancy rates of AMs with scores of 1, 2, 3, 4, and 5 were 0% (0/12), 0% (0/111), 1.2% (1/77), 50% (10/20), and 100% (17/17), respectively. The O-RADS MRI score showed 96.3% sensitivity, 95.2% specificity, and 95.3% accuracy in malignancy prediction. The AUC for the differentiation of benign and malignant masses were 0.983. False positivity rate was high in cases with an O-RADS MRI score of 4 (50%). Conclusion The O-RADS MRI score, based on a simplified MRI protocol, has high accuracy and validity in distinguishing benign from malignant sonographically indeterminate AMs. Its use in clinical practice can classify the malignancy risks of masses and prevent unnecessary surgery in benign lesions.
Recruitment of Community-Based Samples: Experiences and Recommendations for Optimizing Success
Authors: Garnett Anna , Northwood Melissa 
Published: November 2021

Background Recruitment in health and social science research is a critically important but often overlooked step in conducting successful research. The challenges associated with recruitment pertain to multiple factors such as enrolling groups with vulnerabilities, obtaining geographic, cultural, and ethnic representation within study samples, supporting the participation of less accessible populations such as older adults, and developing networks to support recruitment. Purpose This paper presents the experiences of two early career researchers in recruiting community-based samples of older adults, their caregivers, and associated health providers. Methods Challenges and facilitators in recruiting two community-based qualitative research samples are identified and discussed in relation to the literature. Results Challenges included: identifying potential participants, engaging referral partners, implementing multi-methods, and achieving study sample diversity. Facilitators included: making connections in the community, building relationships, and drawing on existing networks. Conclusions Findings suggest the need for greater recognition of the importance of having clear frameworks and strategies to address recruitment prior to study commencement as well as the need to have clear outreach strategies to optimize inclusion of marginalized groups. Recommendations and a guide are provided to inform the development of recruitment approaches of early career researchers in health and social science research.

Published: November 2021

Objective To compare the use of a computer simulation by Mimics software and the water displacement method as means for measurement of alveolar cleft volume on cone beam computed tomography (CBCT) data. Design Prospective study. Settling Institutional research. Patients Patients with unilateral complete cleft lip and palate (UCCLP) who would undergo alveolar bone grafting. Interventions CBCT images of twenty patients with UCCLP were included in the study. In the first method, the water displacement method was adopted to measure volume of plasticine filled in the alveolar cleft imprinted on 3D printed model of maxilla. In the second method a volumetric assessment function in Mimics software was adopted to measure volume of 3D virtual model of alveolar cleft constructed from CBCT images. A comparison on the alveolar cleft volumes derived from the two methods was assessed using the statistical paired t-test. Main Outcome Measure The paired-t test showed no statistically significant difference between alveolar cleft volumes measured by the two methods ( P = 0.075). Results Mean volume of the alveolar cleft measured by the water displacement method was 1.03 ± 0.31 ml whereas by the computer simulation using Mimics software the value was 1.00 ± 0.31 ml. The mean difference between the two methods was 0.03 ± 0.08 ml. Conclusion The computer simulation by Mimics software as a means for measurement of alveolar cleft volume on CBCT data is as accurate as the measurement by the water displacement method.

Published: November 2021

Purpose To describe features of uveitis-glaucoma-hyphema (UGH) syndrome, using Anterior Segment-Optical Coherence Tomography (AS-OCT) and Ultrasound Biomicroscopy (UBM) and to evaluate the diagnostic role of AS-OCT as an imaging technique alternative to UBM. Design Retrospective case series. Methods Four eyes of 4 patients with UGH syndrome were analyzed. All patients reported previous uncomplicated cataract surgery with in-the-bag implantation of single-piece-intraocular lens (IOL). They underwent at presentation complete ophthalmological examination and imaging with slit-lamp anterior segment photographs, UBM and AS-OCT. Results Although AS-OCT did not allow to visualize the structures behind the iris, it displayed a contact between IOL (plate and/or haptics) and iris and IOL tilting in 3 out of 4 eyes. AS-OCT directly detected the cause of UGH syndrome in one eye, 2 eyes required some expedients to display the iris chafing, like scans in mydriasis and/or patient's gaze direction change. AS-OCT did not allow to appreciate the IOL-iris contact (showed by UBM technique) only in one eye, probably due to the change of patient position from supine to sitting, and consequent anteriorization of iris diaphragm. Furthermore AS-OCT showed fine details, as capsular bag collapse and indirect signs of haptic malposition in 3 out of 4 eyes. Conclusion AS-OCT is a non-invasive technique that allows to determine IOL position and IOL-uveal contact in selected cases of UGH syndrome. Considering AS-OCT and UBM advantages and limitations, AS-OCT should be used as first imaging modality when clinical diagnosis is uncertain. When UGH diagnosis cannot be verified using AS-OCT, UBM should be performed.

Published: November 2021

Purpose To analyze the tomographically non-affected second eyes of keratoconus patients using the Corvis ST to detect any biomechanical abnormalities or subclinical keratoconus. Methods In this retrospective, single-center, consecutive case series 244 eyes of 122 keratoconus patients were analyzed between November 2020 and February 2021. Fourteen fellow eyes fulfilled the inclusion criteria and showed no clinical or tomographic signs of keratoconus. Main outcome measures included best-corrected visual acuity, tomographic and biomechanical analyses using Scheimpflug imaging: Pentacam and Corvis ST (Oculus, Wetzlar, Germany). Tomographic analyses included anterior and posterior simulated keratometry, K-Max, central corneal thickness, thinnest corneal thickness, Belin/Ambrosio Ectasia Display, and the ABCD grading system. For biomechanical analyses, the corneal biomechanical index (CBI) and tomographic biomechanical index were used. Results The mean best-corrected visual acuity was 0.01 ± 0.10 logMAR. Mean K-Max was 43.79 ± 1.12 D, mean central corneal thickness 529 ± 25 µm, mean thinnest corneal thickness 524 ± 23 µm, and mean Belin/Ambrosio Ectasia Display 1.0 ± 0.32. The mean CBI was 0.30 ± 0.21. Regular CBI values were found in six of 14 patients. The mean tomographic biomechanical index was 0.47 ± 0.22 with regular values observed in only two of 14 patients. No signs of tomographic or biomechanical abnormalities were shown in only one of 14 keratoconus fellow eyes, with regular ABCD, Belin/Ambrosio Ectasia Display, CBI and tomographic biomechanical index values. Conclusions Tomographically normal fellow eyes of keratoconus patients are rare. In these cases, a biomechanical analysis of the cornea may help detect a subclinical keratoconus. The tomographic biomechanical index was the most sensitive index to verify a mild ectasia.

Purpose To evaluate the outcomes and complications of scleral buckle surgery alone or combined with pneumatic retinopexy (pneumatic buckle) for the treatment of primary rhegmatogenous retinal detachment. Design Retrospective chart review. Participants Two hundred thirteen patients with rhegmatogenous retinal detachment of whom 101 underwent primary scleral buckle surgery at Rabin Medical Center in 2005–2015 (SB group) and 112 underwent pneumatic buckle surgery at Royal Alexandra Hospital in 2013–2015 (PB group). Methods All patients were followed for ≥12 months. Data on clinical and surgical parameters, outcome, and complications were collected from the medical files. Main Outcome Measures Best corrected visual acuity and anatomical outcomes. Results At 12 months, average best corrected visual acuity was 0.3 logMar in the SB group and 0.42 logMar in the PB group ( P < 0.05). Rates of anatomical reattachment were high and similar in the two groups (99% and 97%, respectively, P = 0.623). The SB group had a higher percentage of patients requiring additional laser applications (21% vs. 7%; P < 0.01) and buckle readjustment surgery (6% vs. 0; P = 0.01), and the PB group had a higher percentage of patients who required postoperative pars plana vitrectomy (30% vs. 17%; P = 0.03). Conclusion Scleral buckle surgery alone is efficient for the treatment of rhegmatogenous retinal detachment. Its combination with pneumatic retinopexy usually has no significant added value in terms of anatomical reattachment rate. Outcomes of Pneumatic buckling vs Scleral Buckling for RRD

Objective: To evaluate whether oral contraceptive (OC) use is associated with the risk of a second attack and disability accrual in women with a clinically isolated syndrome (CIS) and early multiple sclerosis (MS). Methods: Reproductive information from women included in the Barcelona CIS prospective cohort was collected through a self-reported cross-sectional survey. We examined the relationship of OC exposure with the risk of a second attack and confirmed Expanded Disability Status Scale of 3.0 using multivariate Cox regression models, adjusted by age, topography of CIS, oligoclonal bands, baseline brain T2 lesions, body size at menarche, smoking, and disease-modifying treatment (DMT). OC and DMT exposures were considered as time-varying variables. Findings were confirmed with sensitivity analyses using propensity score models. Results: A total of 495 women were included, 389 (78.6%) referred to ever use OC and 341 (68.9%) started OC before the CIS. Exposure to OC was not associated with a second attack (adjusted hazard ratio (aHR) = 0.73, 95% confidence interval (CI) = 0.33–1.61) or disability accrual (aHR = 0.81, 95% CI = 0.17–3.76). Sensitivity analyses confirmed these results. Conclusion: OC use does not modify the risk of second attack or disability accrual in patients with CIS and early MS, once considered as a time-dependent exposure and adjusted by other potential confounders.
The role of parental advocacy in addressing service disparities for transition-aged youth on the autism spectrum

Published: November 2021

Youth with autism spectrum disorder (ASD) face challenges accessing needed services as they transition to adulthood. Correlates of service access identified in the literature—such as family resources, race/ethnicity, or youth functioning—can be difficult to change and may not be feasible targets for intervention. This study focused on a potential contributor to service access that is malleable: parental advocacy. Specifically, we examined the association between parental advocacy activities and number of services among transition-aged youth with ASD, after accounting for indicators of youth functioning and family demographic variables (high school exit, co-occurring intellectual disability, social impairments, adaptive behaviors, race/ethnicity, state of residence, family income, and parental depression). Participants included 185 families of youth with ASD who are part of an ongoing randomized controlled trial. Data were collected at baseline (prior to intervention) via parental questionnaire and structured interview. Using hierarchical regression analyses, we found that parental advocacy activities were significantly and strongly associated with service receipt after controlling for youth functioning and family demographic factors. Youth whose parents are less involved in advocacy activities might be at-risk for service disparities. To close the gaps for service disparities, future interventions may target parental advocacy skills. Lay abstract It can be difficult for youth on the autism spectrum to get the services they need after they leave high school. Because of this, many studies have examined the different factors that are related to service access. These studies have shown that youth on the autism spectrum who belong to an underrepresented racial or ethnic group or whose families have lower incomes are less likely to receive the services that they need. However, it is difficult or impossible to change things like race/ethnicity or family income. It is important to also identify factors that might improve service access that we can change. One potential factor that fits into this category is parental advocacy activities. Using data collected from 185 parents of youth on the autism spectrum, we found that more parental advocacy activities were related to youth receiving more services, even after accounting for variables related to the functioning of the youth (e.g. whether they have an intellectual disability, their autism symptom severity) and demographic information about the family (e.g. state in which they live, parental race/ethnicity, and family income). Our findings suggest that building parental advocacy skills may be one important way to increase the number of services that youth on the autism spectrum receive as they transition to adulthood.
