AbstractAimsThis prospective multicenter observational study evaluated postprostatectomy incontinence treatment outcomes with Virtue male sling at 12 and 36 months.MethodsObjective assessment was based on a 24‐h pad weight test with improvement defined by a decrease >50% and cure by less than 1.3 g. Subjective assessment was based on the patient global impression of improvement and International Consultation on Incontinence Questionnaire‐urinary incontinence‐short form (ICIQ‐UI‐SF) questionnaires. Subgroups were analyzed by baseline severity of incontinence on a 24‐h‐pad test, body mass index (BMI), and pads usage. Factors associated with treatment response were assessed using logistic regression at Months 36. Complications were reported.ResultsWe analyzed data from 117 men. Objective and subjective improvement were achieved in 54% and 35% and 51% and 34% at 12 and 36 months, respectively. Twenty‐one percent and 19% were considered cured, respectively, at 12 and 36 months. No differences per baseline incontinence severity, BMI and pads usage were found at 36 months. Mean ICIQ‐UI‐SF score decreased from 15 to 9. Predictive factors were BMI, postvoid residual urine, number of nighttime urination, and ICIQ total score. Seven Clavien–Dindo Grade III (5.1%) including four Virtue sling revisions were reported. The most frequent Grade II complications were overactive bladder symptoms and pain reported in 10.3% and 2.9%, respectively. No complications required explantation.ConclusionsVirtue male sling is safe and effective in males with mild to severe postprostatectomy urinary incontinence over 36 months. Virtue could be considered an interesting option for postradical prostatectomy urinary incontinence with positive results over time even in patients with high BMI. The predictive model should be validated by further studies.

AbstractBackgroundCoronavirus disease 2019 (COVID‐19) is known to cause not only respiratory but also neuropsychiatric symptoms, which are assumed to be derived from a cytokine storm and its effects on the central nervous systems. Patients with COVID‐19 who develop severe respiratory symptoms are known to show severe neuropsychiatric symptoms such as cerebrovascular disease and encephalopathy. However, the detailed clinical courses of patients with neuropsychiatric symptoms caused by mild or asymptomatic COVID‐19 remain poorly understood. Here, we present a case of COVID‐19 who presented with severe and prolonged neuropsychiatric symptoms subsequent to mild respiratory symptoms.Case presentationA 55‐year‐old female with COVID‐19 accompanied by mild respiratory symptoms showed delusion, psychomotor excitement, and poor communication ability during quarantine outside the hospital. Considering her diminished respiratory symptoms, her neuropsychiatric symptoms were initially regarded as psychogenic reactions. However, as she showed progressive disturbance of consciousness accompanied by an abnormal electroencephalogram, she was diagnosed with post‐COVID‐19 encephalopathy. Although her impaired consciousness and elevated cytokine level improved after steroid pulse therapy, several neuropsychiatric symptoms, including a loss of concentration, unsteadiness while walking, and fatigue, remained.ConclusionsThis case suggests the importance of both recognizing that even apparently mild COVID‐19‐related respiratory symptoms can lead to severe and persistent neuropsychiatric symptoms, and elucidating the mechanisms, treatment, and long‐term course of COVID‐19‐related neuropsychiatric symptoms in the future.
Mixed hp finite element method for singularly perturbed fourth order boundary value problems with two small parameters

Published: December 2021

AbstractWe consider fourth order singularly perturbed boundary value problems with two small parameters, and the approximation of their solution by the version of the finite element method on the spectral boundary layer mesh from Melenk et al. We use a mixed formulation requiring only basis functions in two‐dimensional smooth domains. Under the assumption of analytic data, we show that the method converges uniformly, with respect to both singular perturbation parameters, at an exponential rate when the error is measured in the energy norm. Our theoretical findings are illustrated through numerical examples, including results using a stronger (balanced) norm.

Published: December 2021

AbstractNanocomposites are promising for manufacturing small diameter vascular biodegradable polymer‐based stents (BDPSs) to obviate frequent ordeals of in‐stent restenosis and stent thrombosis by providing appropriate support for vasculature as well as tissue regeneration. Freeform (without any support), vascular‐scale, small diameter (2 mm) tubular nanocomposites were fabricated using 3D printing based on fused filament fabrication (FFF). The nanocomposites were constructed using bioresorbable polylactic acid (PLA) and carbon quantum dots (CQDs). The3D‐printing process of the PLA‐CQD nanocomposites was optimized to deliver improved structural integrity as well as mechanical and biological properties for cardiovascular systems. The PLA‐CQD composites demonstrated excellent processability, hydrophilicity, tensile strength, compressive strength, radial stability, and cell proliferation relative to pure PLA. The results show that the addition of CQDs enhances stent properties significantly, such as, composite hydrophilicity by about 25%, tensile strength by 24%, compressive strength by 66%, and cell proliferation by 50% compared to PLA alone. The results show that the combination of 3D printing with PLA‐CQD nanocomposites could be a viable method to produce bioresorbable nanocomposites for cardiovasculatures with noninvasive imaging for monitoring composite condition and cell growth.

AbstractBackgroundSurvivors of pediatric acute lymphoblastic leukemia (ALL) are at increased risk of neurocognitive weakness in the areas of attention, executive function, and processing speed. Although fatigue and sleep disturbances are frequent complications of ALL therapy and associated with cognitive functions, the impact of fatigue and sleep profiles during active ALL treatment on posttreatment neurocognitive performance has received limited attention.MethodsPediatric patients (n = 120) with ALL (diagnosed 2011–2016) who completed fatigue and sleep questionnaires at four time points during active treatment were enrolled in a study of neurocognitive performance. Latent class growth analysis identified subgroups of patients with similar sleep and fatigue profiles during treatment. Neurocognitive performance collected >6 months post treatment on 40 participants was compared between latent classes using multivariable linear regression models.ResultsParticipants (57.5% male and 79.1% Hispanic or non‐Hispanic White) were classified into one of two fatigue and sleep profiles: Class 1 characterized by mild fatigue and sleep disturbances during treatment (50.8%), and Class 2 characterized by higher levels of fatigue and sleep disturbances (49.2%). Posttreatment cognitive performance was in the normal range for most measures, but significantly below normative means for executive function, verbal short‐term memory, attention, and distractability measures. Compared to Class 1, Class 2 demonstrated significantly (p < .05) poorer posttreatment neurocognitive performance, particularly in measures of attention.ConclusionsOur findings indicate that fatigue and sleep disturbances during the first year of pediatric ALL therapy may impact long‐term neurocognitive performance. Sleep and fatigue may be targets for intervention to preserve cognitive functioning in survivors.
City‐level housing trust funds: Lessons from key case studies
Authors: Beard Virginia 
Published: December 2021

AbstractThe United States needs more housing. The need for the creation of new housing and rehabilitation of existing housing stock at price points that middle‐ and working‐class families can afford has created a pent‐up demand revealed in housing assessment reports across the country. Housing trust funds have been increasingly used as one tool among other efforts to meet this proven need for more affordable housing (affordable housing is understood to mean paying less than 30% of household income on housing costs, otherwise stated as the 30% of income affordability threshold). This paper explores this important tool, overviewing crucial information needed by scholars of affordable housing as well as policymakers, housing advocates, and other stakeholders to understand and act in the use of this vehicle to support affordable housing. Little research exists on understanding the way housing trust funds are constructed and used looking across specific funds. There exists an even greater gap in investigation of the efforts of housing trust funds at local levels. Thus, this paper examines housing trust funds in a comparative manner and does so using city‐level, as opposed to state or federal‐level, funds. There exist key lessons that can be learned from cities around the country that are already engaged in such work. There are three crucial aspects that define successful housing trust funds: funds must be rooted in empirical data on housing needs and feasibility, supported by a dedicated revenue stream drawing ideally from multiple sources is indispensable and management of the fund should be established in context with other efforts at providing and retaining housing at affordable prices. The combination of housing trust fund dollars with other efforts, made stable by dedicated sources of revenue and ongoing research makes them a tool that is a successful addition to work done on supplying the demand for housing at needed price points.
Adaptive preassigned finite‐time stability of nonlinear systems with time‐varying powers and full‐state constraints
Authors: Wu You , Xie Xue‐Jun 
Published: December 2021

AbstractThis article discusses adaptive preassigned finite‐time stability of nonlinear systems with unknown time‐varying powers and full‐state constraints. By introducing a concept of practical preassigned finite‐time stable, constructing finite‐time performance functions and nonlinear transformed functions, and integrating high‐power and low‐power terms into dynamic surface control design, an adaptive state‐feedback controller is designed to eliminate the effects of unknown powers and serious unknown parameters in system dynamics, and decrease the computational burden in previous design methods. It is proved that all the signals of the closed‐loop system are bounded, asymmetric time‐varying full‐state constraints are not transgressed, and system states converge to a prescribed arbitrarily small region around zero after a preassigned settling time. Two simulation examples show the effectiveness and advantages of this control scheme.
Scenario‐based hydrodynamic simulation of adaptive strategies for urban design to improve flood resilience: A case study of the Mingzhu Bay Region, Guangzhou, Greater Bay Area
Authors: Lu Peijun , Sun Yimin 
Published: December 2021

AbstractThe Pearl River Delta is a complex ecological‐artificial system. The low‐elevation landform and land subsidence make the Guangdong‐Hong Kong‐Macao Greater Bay Area (GBA) more vulnerable to heavy rainstorms with sea‐level rise in the future. Therefore, this study discussed how to optimize the delta‐related built environment based on locality via cooperation between urban designers and hydrology researchers so that urban development in the GBA can adapt to water disasters. First, this study proposed three adaptive spatial strategies for urban design to improve flood resilience: (a) adding more sunken space and rearranging the locations of manholes; (b) adding more retention space to the waterway system; and (c) improving foundation elevation for suitable development intensity. With the prediction of sea‐level rise and land subsidence, four different scenarios were defined. Second, a coupled 1D/2D hydrodynamic model was built for scenario‐based urban inundation simulations. Third, a Python workflow was developed to reveal the water volume exchange, and an ArcMap workflow to realize the impact of inundation. The simulation results show that (a) more sunken space can lower the peak runoff discharges and decrease the runoff coefficient; (b) more retention space can extend the capacity of the urban drainage system and adapt to the rise of sea level; and (c) improving foundation elevation and more sunken green space can direct the surface water to submerge urban land in reasonable order, which can protect the significant infrastructures and development lands. This paper suggests that these adaptive spatial strategies can serve as solutions for resilience development.

Published: December 2021

AbstractPhotonic microbeads containing crystalline colloidal arrays are promising as a key component of structural‐color inks for various applications including printings, paintings, and cosmetics. However, structural colors from microbeads usually have low color saturation and the production of the beads requires delicate and time‐consuming protocols. Herein, elastic photonic microbeads are designed with enhanced color saturation through facile photocuring of oil‐in‐oil emulsion droplets. Dispersions of highly‐concentrated silica particles in elastomer precursors are microfluidically emulsified into immiscible oil to produce monodisperse droplets. The silica particles spontaneously form crystalline arrays in the entire volume of the droplets due to interparticle repulsion which is unperturbed by the diffusion of the surrounding oil whereas weakened for oil‐in‐water droplets. The crystalline arrays are permanently stabilized by photopolymerization of the precursor, forming elastic photonic microbeads. The microbeads are transferred into the refractive‐index‐matched biocompatible oil. The high crystallinity of colloidal arrays increases the reflectivity at stopband and the index matching reduces incoherent scattering at the surface of the microbeads, enhancing color saturation. The colors can be adjusted by mixing two distinctly colored microbeads. Also, low stiffness and high elasticity reduce foreign‐body sensation and enhance fluidity, potentially serving as pragmatic structural colorants for photonic inks.

AbstractOrganic electrode materials with the advantages of renewability, environment‐friendliness, low cost, and high capacity have received widespread attention in recent years for sodium‐ion batteries. However, small molecular organic materials suffer from issues such as low conductivity and the high dissolution rate in electrolytes. Herein, a phthalocyanine derivative (TPcDS) with a large non‐localized π‐electron system, obtained through thermodynamic polymerization of 4‐aminophthalonitrile (AP) monomers, is designed to address these issues. According to the density function theory calculation, six sodium ions can be attracted by one polymer molecule, indicating a high theoretical capacity of 375 mA h g‐1. The TPcDS molecule realizes sodium storage through a non‐localized π‐electron system of phthalocyanine macrocycles. When employed as an anode material for sodium‐ion batteries, the functional groups of phthalocyanine macrocycles, such as CN groups in TPcDS, experience obviously reversible structural variation upon discharge/charge. A high reversible capacity of 364 mAh g‐1 is achieved at a current density of 0.05 A g‐1, and a charge capacity of as high as 246 mAh g‐1 is still maintained after 500 cycles at 0.1 A g‐1. This work provides an effective strategy for the design and synthesis of new oligomeric organic electrode materials.

Published: December 2021

AbstractAquatic organisms within the Cephalopoda family (e.g., octopuses, squids, cuttlefish) exist that draw the surrounding fluid inside their bodies and expel it in a single jet thrust to swim forward. Like cephalopods, several acoustically powered microsystems share a similar process of fluid expulsion which makes them useful as microfluidic pumps in lab‐on‐a‐chip devices. Herein, an array of acoustically resonant bubbles are employed to mimic this pumping phenomenon inside an untethered microrobot called CeFlowBot. CeFlowBot contains an array of vibrating bubbles that pump fluid through its inner body thereby boosting its propulsion. CeFlowBots are later functionalized with magnetic layers and steered under combined influence of magnetic and acoustic fields. Moreover, acoustic power modulation of CeFlowBots is used to grasp nearby objects and release it in the surrounding workspace. The ability of CeFlowBots to navigate remote environments under magneto‐acoustic fields and perform targeted manipulation makes such microrobots useful for clinical applications such as targeted drug delivery. Lastly, an ultrasound imaging system is employed to visualize the motion of CeFlowBots which provides means to deploy such microrobots in hard‐to‐reach environments inaccessible to optical cameras.

Published: December 2021

AbstractTraditional and lightweight cryptography primitives and protocols are insecure against quantum attacks. Thus, a real‐time application using traditional or lightweight cryptography primitives and protocols does not ensure full‐proof security. Post‐quantum cryptography is important for the internet of things (IoT) due to its security against quantum attacks. This paper offers a broad literature analysis of post‐quantum cryptography for IoT networks, including the challenges and research directions to adopt in real‐time applications. The work draws focus towards post‐quantum cryptosystems that are useful for resource‐constraint devices. Further, those quantum attacks are surveyed, which may occur over traditional and lightweight cryptographic primitives.
Atypical cytomorphologic description of a seminoma in a rabbit
Authors: Alonso Flavio H. 
Published: December 2021

AbstractSeminoma is reported as a rare disease associated with specific micro‐morphologic findings. In the present report, we describe the case of a testicular seminoma in a 7‐year‐old Holland Lop rabbit, in which the cytology presented an atypical pattern. Upon presentation, the left testicle was severely enlarged, and the patient also had a history of radiation therapy for a previously diagnosed thymoma. Following excision and histopathology of the abnormal organ, results showed a mixed intratubular‐diffuse pattern with evidence of torsion. Moreover, cytology revealed a cohesive pattern with multiple malignancy criteria. To our knowledge, this is the first published report of a seminoma with these cytologic features.

AbstractA 6‐year‐4‐month‐old male entire Dalmatian was referred for acute onset ataxia, obtundation, head pressing, dropped jaw and vertical nystagmus. Neurological examination identified vestibular ataxia, positional left‐sided ventrolateral strabismus, static vertical nystagmus, dropped jaw, ptyalism, inconsistently present bilateral palpebral reflexes, menace responses and gag reflex. Based upon neurological examination, multiple cranial nerves were affected, and cranial polyneuropathy was suspected. Peripheral or central cranial polyneuropathy could not be differentiated at this stage. Forebrain disease could not be excluded considering the dog's clinical signs. MRI of the head identified bilaterally enlarged hyperintense and contrast‐enhancing trigeminal and vestibulocochlear nerves. Cisternal cerebral spinal fluid analysis was normal. Cranial polyneuritis was suspected. Medical management was initiated with an immunosuppressive dose of prednisolone and ciclosporin and an improvement of the dog's clinical signs was observed. This case is the first to describe a diagnostic approach and treatment plan for suspected cranial polyneuritis.
