Eddy–Internal Wave Interactions: Stimulated Cascades in Cross-Scale Kinetic Energy and Enstrophy Fluxes
Authors: Barkan Roy , Srinivasan Kaushik , McWilliams James C. 
Published: March 2024

Abstract
The interactions between oceanic mesoscale eddies, submesoscale currents, and internal gravity waves (IWs) are investigated in submesoscale-resolving realistic simulations in the North Atlantic Ocean. Using a novel analysis framework that couples the coarse-graining method in space with temporal filtering and a Helmholtz decomposition, we quantify the effects of the interactions on the cross-scale kinetic energy (KE) and enstrophy fluxes. By systematically comparing solutions with and without IW forcing, we show that externally forced IWs stimulate a reduction in the KE inverse cascade associated with mesoscale rotational motions and an enhancement in the KE forward cascade associated with divergent submesoscale currents, i.e., a “stimulated cascade” process. The corresponding IW effects on the enstrophy fluxes are seasonally dependent, with a stimulated reduction (enhancement) in the forward enstrophy cascade during summer (winter). Direct KE and enstrophy transfers from currents to IWs are also found, albeit with weaker magnitudes compared with the stimulated cascades. We further find that the forward KE and enstrophy fluxes associated with IW motions are almost entirely driven by the scattering of the waves by the rotational eddy field, rather than by wave–wave interactions. This process is investigated in detail in a companion manuscript. Finally, we demonstrate that the stimulated cascades are spatially localized in coherent structures. Specifically, the magnitude and direction of the bidirectional KE fluxes at submesoscales are highly correlated with, and inversely proportional to, divergence-dominated circulations, and the inverse KE fluxes at mesoscales are highly correlated with strain-dominated circulations. The predominantly forward enstrophy fluxes in both seasons are also correlated with strain-dominated flow structures.

Objective Lumbar fractures are the most common spinal injuries, and surgery is required for severe fracture. This study aimed to investigate the variations in motion and stress in varying states of activity after minimally invasive and traditional open pedicle screw placement for L1 vertebral fracture stabilization. Methods We studied a male volunteer (26 years old) with no history of chronic back pain or lumbar spine trauma. We used the finite element method for this investigation. Using finite element software, we created a three-dimensional model of L1 vertebral compression fracture. We also constructed models for four percutaneous pedicle screws spanning the fractured vertebra and four screws traversing the damaged vertebra with transverse fixation. Results In all three-dimensional movement directions, the open pedicle fixation system experienced maximum stress higher than its percutaneous counterpart. With axial spinal rotation, von Mises stress on the traditional open pedicle screw was considerably lower than that with percutaneous pedicle fixation, but peak stress was elevated at the transverse connection. Traditional open pedicle fixation displayed less maximum displacement than percutaneous pedicle internal fixation. Conclusions During axial spinal movements, high peak stress is observed at the transverse connection. Patients should avoid excessive axial rotation of the spine during recovery.

Published: March 2024

Objectives To evaluate the efficacy of water irrigating devices, powered toothbrushes, and active repeated oral hygiene reminders on oral hygiene of fixed orthodontic patients. Materials and Methods This was a randomized, examiner-blind clinical trial involving fixed orthodontic appliance patients. Patients were recruited within six months of bonding on both the arches. Eighty patients were randomly assigned to four groups; groups 1 and 3 subjects received standard oral hygiene procedures and used manual orthodontic toothbrushes, and subjects in groups 2 and 4 used powered toothbrushes and water irrigators for oral hygiene maintenance during the study period. In addition, repeated oral hygiene reminders via SMS were sent to subjects in groups 1 and 2, whereas groups 3 and 4 subjects received only oral motivation. The principal investigator assessed the plaque index (PI) and gingival index (GI) at baseline (T0) and after 2, 4, 8, and 12 weeks, that is, T1, T2, T3, and T4, respectively. Results Group 2 and group 4 subjects showed statistically significant reduction in PI ( p < .001) and GI ( p < .001) scores at the end of study interval; however, the magnitude of decrease was less in group 4 in comparison to group 2. Intergroup comparisons between group 1 versus group 3 and group 2 versus group 4 were made to evaluate the efficacy of reminders. Statistically significant reduction was observed in group 2 as compared to group 4 at T4 ( p < .001) when compared to T1 ( p < .87). Conclusion Using powered toothbrushes and oral irrigators resulted in a statistically more significant reduction in plaque and gingivitis scores than conventional procedures. Active reminders had a catalytic effect in improving the oral hygiene.

Published: March 2024

Objectives In addition to various immunosuppressive agents, belimumab and anifrolumab became available in Japan. We aimed to investigate glucocorticoid-free clinical remission in a single-centre retrospective cohort in October 2023. Methods Our cohort included patients with SLE who needed to start or increase glucocorticoids for disease activity and were followed up for more than 1 year. We investigated the rate of achievement of clinical remission off corticosteroids (CR off C), defined as no clinical score on the SLEDAI-2K without glucocorticoids, baseline predictors of CR off C, medications used when CR off C was achieved, and flare rates following CR off C. Results Out of the 60 patients followed for an average of 5.4 (±2.6) years, 17 (28.3%) achieved CR off C in 3.6 (±1.2) years after enrolment. Use of belimumab and anifrolumab accounted for eight (47.1%) of the achievers. Among the baseline data, male sex, recent enrolment, high glucocorticoid dose, and detection of immune complex (IC) significantly predicted CR off C, while lupus nephritis (LN) and a low C3 level tended to predict it. In the multivariate analysis, IC detection was the only predictor of CR off C. Clinical flares were observed in 5.9% of the achievers during a median 1.2 years after achievement of CR off C. Conclusion In the era of biologics, CR off C was achieved in 28.3% of the patient cohort requiring the start or increase of glucocorticoids for disease activity, with a relatively low rate of flares, suggesting that glucocorticoid-free clinical remission is an achievable target in SLE. IC disease, represented by male sex or nephritis, is likely to benefit from currently available medications.

Purpose To compare the intraocular pressure (IOP) profile and the incidence of IOP spikes following selective laser trabeculoplasty (SLT) between pigmentary glaucoma (PG) and primary open-angle glaucoma (POAG). Materials and Methods Retrospective comparative study of 65 PG eyes of 51 patients matched with 65 POAG eyes of 65 patients who received SLT. Matching was done based on age, gender, glaucoma severity, pre-laser IOP, and number of medications. Post-SLT IOP spike was defined as IOP elevation ≥5mmHg, 30-45 min after the laser. Results In PG and POAG groups, the average age was 62.33 ± 9.18 and 62.58 ± 9.19 years (p = 0.95). The glaucoma severity (p = 0.708), baseline IOP (PG = 21.61 ± 1.34mmHg vs. POAG = 21.13 ± 5.09mmHg, p = 0.943), and number of topical glaucoma medications(PG = 2.34 ± 1.34 vs. POAG = 2.1 ± 1.41, p = 0.342) were comparable. More PG patients were on oral acetazolamide (PG = 26.15% vs. POAG = 1.5%, p < 0.001). Average logMAR visual acuity was significantly higher in the POAG group (0.207 ± 0.3 vs. 0.192 ± 0.37, p = 0.012). Eyes with PG received lower laser energy (POAG = 63.65 ± 22.03 mJ vs. PG = 43.71 ± 25.68 mJ, p < 0.001). IOP spikes were recorded in 5 PG eyes (7.6%) and none in the POAG group (p = 0.058). Failure rates were similar (PG = 50.7% and POAG = 43.1%, p = 0.205). In multivariable analysis, only pre-laser IOP (coefficient = 2.154 [CI: 0.765–3.543], p = 0.003) was a significant predictor of IOP change percentage after 12 months. Conclusions SLT was comparably effective in both PG and POAG. IOP spikes were observed only in the PG group, though the total laser energy was lower in this group compared with POAG.

Authors: Li Siying , Li Xiaoxin , Qu Jinfeng 
Published: March 2024

Background Wolfram-like syndrome (WFLS) is an autosomal dominant inherited disease characterized by a single heterozygous pathogenic variant in the WFS1 gene. Its clinical presentation is similar to autosomal recessive Wolfram syndrome. Case presentation We reported a case of a 10-year-old boy and his family members who initially experienced hearing impairment (HI), followed by optic atrophy. Genetic testing revealed the presence of a WFS1 variant (chr4-6302385 exon8 NM_006005.3: c.2590G > A, p. Glu864Lys). Conclusion Wolfram-like syndrome, a rare neurodegenerative genetic disorder, manifested as deafness, optic atrophy, and diabetes mellitus. There hasn’t been a definite treatment yet. Early identification of the variant in the WFS1 gene is beneficial for genetic counseling.
Natalizumab reduces loss of gray matter and thalamic volume in patients with relapsing-remitting multiple sclerosis: A post hoc analysis from the randomized, placebo-controlled AFFIRM trial

Published: March 2024

Background: Loss of brain gray matter fractional volume predicts multiple sclerosis (MS) progression and is associated with worsening physical and cognitive symptoms. Within deep gray matter, thalamic damage is evident in early stages of MS and correlates with physical and cognitive impairment. Natalizumab is a highly effective treatment that reduces disease progression and the number of inflammatory lesions in patients with relapsing-remitting MS (RRMS). Objective: To evaluate the effect of natalizumab on gray matter and thalamic atrophy. Methods: A combination of deep learning–based image segmentation and data augmentation was applied to MRI data from the AFFIRM trial. Results: This post hoc analysis identified a reduction of 64.3% ( p = 0.0044) and 64.3% ( p = 0.0030) in mean percentage gray matter volume loss from baseline at treatment years 1 and 2, respectively, in patients treated with natalizumab versus placebo. The reduction in thalamic fraction volume loss from baseline with natalizumab versus placebo was 57.0% at year 2 ( p < 0.0001) and 41.2% at year 1 ( p = 0.0147). Similar findings resulted from analyses of absolute gray matter and thalamic fraction volume loss. Conclusion: These analyses represent the first placebo-controlled evidence supporting a role for natalizumab treatment in mitigating gray matter and thalamic fraction atrophy among patients with RRMS.

Long-term outcome of percutaneous endovascular stenting in external iliac artery endofibrosis
Authors: Sharifi Mohsen , Snyder Robert , Sharifi Iman , White Emily 
Published: March 2024

Background: External iliac artery endofibrosis (EIAE) is a rare vascular disease which has been traditionally seen in avid cyclists. The conventional approach has been surgery, although no high-quality evidence suggests superiority of surgery over percutaneous endovascular intervention. There are limited data on the efficacy of stenting in EIAE. Methods: Over a 14-year period, we treated 10 patients (13 limbs) with EIAE with stents. These patients had declined surgery. The mean follow up was 8.4 ± 3.3 years. There were eight women. Five patients were competitive runners, three were cyclists, and two were triathletes. The mean age was 40.7 ± 2.9 years and body mass index was 19.46 ± 1.6. Intravascular ultrasound (IVUS) was used in eight limbs. Results: Procedural success was achieved in all. The recurrence of symptoms occurred in three patients at a mean of 9.3 ± 2.1 months postindex intervention. The other seven patients remained symptom free. IVUS revealed a pathognomonic finding which we termed ‘perfect circle appearance’. It results from symmetric or asymmetric hypertrophy of one or more layers of the arterial wall leading to negative remodeling, which creates a distinct echo dense structure contrasting itself from the luminal blood’s echoluscent appearance. It is identical to IVUS images of diffuse venous stenosis with important implications in the treatment technique. Conclusions: We conclude that stenting in EIAE is safe and effective with a good long-term outcome. It can be an alternative to surgery, particularly in those patients who refuse a surgical approach. The IVUS image is pathognomonic and ‘sine qua non’ of EIAE.
The neurodiversity concept was developed collectively: An overdue correction on the origins of neurodiversity theory

Published: March 2024

We, an international group of autistic scholars of autism and neurodiversity, discuss recent findings on the origins of the concept and theorising of neurodiversity. For some time, the coinage and theorising of the concept of ‘neurodiversity’ has been attributed to Judy Singer. Singer wrote an Honours thesis on the subject in 1998, focused on autistic activists and allies in the autistic community email list Independent Living (InLv). This was revised into a briefer book chapter, published in 1999. Despite the widespread attribution to Singer, the terms ‘neurological diversity’ and ‘neurodiversity’ were first printed in 1997 and 1998, respectively, in the work of the journalist Harvey Blume, who himself attributed them not to Singer but rather to the online community of autistic people, such as the ‘Institute for the Study of the Neurologically Typical’. Recently, Martijn Dekker reported a 1996 discussion in which one InLv poster, Tony Langdon, writes of the ‘neurological diversity of people. i.e. the atypical among a society provide the different perspectives needed to generate new ideas and advances, whether they be technological, cultural, artistic or otherwise’. Going forward, we should recognise the multiple, collective origins of the neurodiversity concept rather than attributing it to any single author. Lay abstract This letter discusses the origins of the concept and theory of neurodiversity. It is important to correctly attribute concept and theories to the people who developed them. For some time, the concept of neurodiversity has primarily been attributed to one person, Judy Singer. We consider the available evidence and show that the concept and theory in fact has multiple origins. We draw particular attention to recent archival findings that show the concept of ‘neurological diversity’ was being used years earlier than previously thought. ‘Neurodiversity’ means the same thing as ‘neurological diversity’ and does not change the theory in any way. We conclude that both the concept of neurological diversity or neurodiversity, and the body of theory surrounding it, should be understood as having been collectively developed by neurodivergent people.
How journalism adapted the Internet in Germany: Results of six newsroom surveys (1997–2014)
Authors: Neuberger Christoph 
Published: March 2024

Based on six newsroom surveys, this article analyzes the history of digital German journalism. The surveys cover a period of 17 years (1997–2014). Periodizing the history of digital journalism into three phases, this article considers the interplay between journalism and journalism research. The results show how journalistic digital media define their role in the relationships between old media and the Internet, digital media and other outlets, and digital media and their audiences. Furthermore, the results substantiate how digital editorial staff define their journalistic identities regarding tasks, rules, and skills. During the first period (surveys conducted in 1997 and 2000), the view from old mass media to the Internet dominated, also in scholarship where the mass media paradigm was extended to the Internet. The second period (surveys conducted in 2006 and 2007) was characterized by clarifying the relationships between journalism and newly emerged outlets. These studies focused on how participative formats (such as Wikipedia and blogs) and search engines could be used for journalistic purposes without compromising quality. These new outlets were not regarded then as much of a threat. This attitude did not change during the third period (surveys conducted in 2010 and 2014). In this phase, too, the studies focused on how editorial staff utilized the ever-increasing number of social media. The six surveys’ different research interests reveal that the reviewed journalism research primarily addressed changing demands in journalistic practice. Therefore, exogenous factors (“the sector”) had a greater impact than endogenous factors (the “scholarship”) on research interests.
Refinement of nBCA embolization technique in treatment of metastatic spinal tumors: Case series and technical report
Authors: McGuire Laura Stone , Nico Elsa , Hossa Jessica , Tshibangu Mpuekela , Mehta Ankit , Alaraj Ali 
Published: March 2024

Background and Objectives Preoperative embolization of metastatic spinal tumors (MSTs) has proven advantageous in limiting intraoperative blood loss (IBL) during resection. N-butyl cyanoacrylate (nBCA) is a liquid embolic agent known for its rapid hemostatic effects. However, nBCA is associated with a higher risk of distal nontarget embolization. This study highlights the refinement of the embolization technique and assesses its efficacy in performing an initial distal segmental artery plug with concentrated nBCA followed by proximal diluted nBCA for MSTs. Methods A retrospective review of patients with MST (2018–2023) was performed. Patients who underwent preoperative nBCA endovascular embolization prior to tumor resection and spinal instrumentation were included. Baseline standard spinal angiography was performed. Results Sixteen patients (13 men, 3 women; 56.0 ± 12.4 years) met inclusion criteria. And 43.75% (7 of 16) had thoracic levels, 37.5% (6 of 16) lumbar, and 18.75% (3 of 16) sacral. The most common primary tumor was renal cell carcinoma (43.75%, 7 of 16). A total of 43 pedicles were embolized (median 3), resulting in complete/near complete obliteration of the tumor blush. Most pedicles (83.7%, 36 of 43) received a single dilute concentration of nBCA; however, 16.3% (7 of 43) received two separate concentrations of nBCA, a denser concentration distally into the segmental artery and a diluted concentration proximally into the tumor bed. Mean IBL was 1150 ± 1201 mL in 3 distal plug patients distal plug patients versus 1625 ± 681 mL in 12 other patients. There were no complications related to embolization. Conclusion Performing a distal, concentrated nBCA plug during preoperative nBCA embolization of MSTs may increase tumor penetration and reduce IBL.

Published: March 2024

Background: Arthroscopic superior capsular reconstruction (ASCR) and reverse shoulder arthroplasty (RSA) have both shown favorable outcomes in patients with irreparable rotator cuff tears (IRCTs). Purpose: To (1) compare the clinical outcomes of ASCR versus RSA in patients aged ≥65 years with IRCTs and (2) compare serial changes in clinical outcomes between treatment groups. Study Design: Cohort study; Level of evidence, 3. Methods: This study included patients with IRCTs without glenohumeral osteoarthritis who underwent either ASCR or RSA between March 2013 and December 2020 and had at least 2 years of follow-up data. We assessed active range of motion, a visual analog scale (VAS) pain score, the American Shoulder and Elbow Surgeons (ASES) score, and the Single Assessment Numeric Evaluation (SANE) score at the preoperative, short-term (postoperative 6-12 months), and final follow-up times. Results: In total, 64 patients (ASCR, 31 patients; RSA, 33 patients) were included. The mean age of patients was 71.3 ± 4.4 and 72.9 ± 4.1 years, and the mean final follow-up duration was 42 ± 21.8 and 37.7 ± 21.7 months in the ASCR and RSA groups, respectively. At the short-term follow-up, RSA achieved significant improvements in all clinical outcomes, except for internal rotation (IR), while ASCR only showed significant improvements in VAS pain, ASES, and SANE scores. Compared with the preoperative period, both ASCR and RSA achieved significant improvements in all clinical outcomes, except for IR in the RSA group at the final follow-up. The ASCR group achieved better IR and ASES scores at the final follow-up, while the time taken to recover from pseudoparalysis was shorter after RSA. The ASCR group showed a 67.8% graft healing rate at the 1-year follow-up, while the RSA group showed 12.1% of scapular notching at the final follow-up. No other postoperative complications were observed in either group. Conclusion: ASCR and RSA achieved favorable clinical outcomes in the study cohort. At the short-term follow-up, RSA showed significant improvements in all clinical outcomes, except for IR, while ASCR only showed significant improvements in VAS pain, ASES, and SANE scores. At the final follow-up, however, ASCR had better IR and ASES scores compared with RSA.
