Authors: Godard-Sebillotte Claire , Strumpf Erin , Sourial Nadia , Rochette Louis , Pelletier Eric , Vedel Isabelle 
Published: September 2021

Background
Whether avoidable hospitalizations in community-dwelling persons with dementia have decreased during primary care reforms is unknown.
Methods
We described the prevalence and trends in avoidable hos­pitalizations in population-based repeated yearly cohorts of 192,144 community-dwelling persons with incident dementia (Quebec, 2000–2015) in the context of a province-wide pri­mary care reform, using the provincial health administrative database.
Results
Trends in both types of Ambulatory Care Sensitive Condition (ACSC) hospitalization (general and older population) and 30-day readmission rates remained constant with average rates per 100 person-years: 20.5 (19.9–21.1), 31.7 (31.0–32.4), 20.6 (20.1–21.2), respectively. Rates of delayed hospital discharge (i.e., alternate level of care (ALC) hospitalizations) decreased from 23.8 (21.1–26.9) to 17.9 (16.1–20.1) (relative change -24.6%).
Conclusions
These figures shed light on the importance of the phenomenon, its lack of improvement for most outcomes over the years, and the need to develop evidence-based policies to prevent avoidable hospitalizations in this vulnerable population.

Published: September 2021

Background
The preferred primary treatment of toe osteomyelitis in diabetic patients is controversial. We compared the outcome of primary nonoperative antibiotic treatment versus digital amputation in patients with diabetes-related chronic digital osteomyelitis.

Methods
We conducted a retrospective medical record review of patients treated for digital osteomyelitis at a single center. Patients were divided into two groups according to initial treatment: 1) nonoperative treatment with intravenous antibiotics and 2) amputation of the involved toe or ray. Duration of hospitalization, number of rehospitalizations, and rate of below- or above-the-knee major amputations were evaluated.

Results
The nonoperative group comprised 39 patients and the operative group included 21 patients. The mean ± SD total duration of hospitalization was 24.05 ± 15.43 and 20.67 ± 15.97 days, respectively (P = .43). The mean ± SD number of rehospitalizations after infection recurrence was 2.62 ± 1.63 and 1.67 ± 1.24, respectively (P = .02). During follow-up, the involved digit was eventually amputated in 13 of the 39 nonoperatively treated patients (33.3%). The rate of major amputation (above- or below-knee amputation was four of 39 (10.3%) and three of 21 (14.3%), respectively (P = .69).

Conclusions
Despite a higher rate of rehospitalizations and a high failure rate, in patients with mild and limited digital foot osteomyelitis in the absence of sepsis it may be reasonable to offer a primary nonoperative treatment for digital osteomyelitis of the foot.

Authors: Olivova Jana , Singh Bibi N. , Casciato Dominick J. 
Published: September 2021

Background
Google Trends proves to be a novel tool to ascertain the level of public interest in pathology and treatments. From anticipating nascent epidemics with data-driven prevention campaigns to identifying interest in cosmetic or bariatric surgery, Google Trends provides physicians real-time insight into the latest consumer trends.

Methods
We used Google Trends to identify temporal trends and variation in the search volume index of four groups of keywords that assessed practitioner-nomenclature inquiries, in addition to podiatric-specific searches for pain, traumatic injury, and common podiatric pathology over a 10-year period. The Mann-Kendall trend test was used to determine a trend in the series, and the Wilcoxon signed-rank test was used to determine whether there was a significant difference between summer and winter season inquiries. Significance was set at P ≤ .05.

Results
The terms “podiatrist” and “foot doctor” experienced increasing Search Volume Index (SVI) and seasonal variation, whereas the terms “foot surgeon” and “podiatric surgeon” experienced no such increase. “Foot pain,” “heel pain,” “toe pain,” and “ankle pain” experienced a significant increase in SVI, with “foot pain” maintaining the highest SVI at all times. Similar results were seen with the terms “foot fractures,” “bunion,” “ingrown toenail,” and “heel spur.” These terms all experienced statistically significant increasing trends; moreover, the SVI was significantly higher in the summer than in the winter for each of these terms.

Conclusions
The results of this study show the utility in illustrating seasonal variation in Internet interest of pathologies today's podiatrist commonly encounters. By identifying the popularity and seasonal variation of practitioner- and pathology-specific search inquiries, resources can be allocated to effectively address current public inquiries. With this knowledge, providers can learn what podiatric-specific interests are trending in their local communities and market their practice accordingly throughout the year.
Healing Rate of Diabetic Foot Wounds When Treated with Serial Debridement in the Presence of Antithrombotic Therapy
Authors: Route Jack 
Published: September 2021

Background
Previous study indicates that pharmacologic antithrombotic therapy may be an inhibitory factor for wound healing and should merit consideration among the other core factors in wound healing optimization.

Methods
This study provides a retrospective analysis of the effect of antithrombotic therapy on wound healing rates of uncomplicated diabetic foot ulcerations. Wounds treated with standard of care in the presence of clinical anticoagulation were compared to control wounds.

Results
The results indicate a statistically significant negative correlation between antithrombotic therapy and diabetic foot wound healing rate. This represents the first study focusing on this correlation in the uncomplicated diabetic foot wound.

Conclusions
This retrospective study demonstrates that antithrombotic therapy has a statistically significant negative effect on healing rates of uncomplicated diabetic foot ulcerations. Both wound area and depth improvement over 4 weeks was significantly better in treated patients who were not on antithrombotic therapy for comorbidity not associated with peripheral arterial disease.
Efficacy of a Single Corticosteroid Injection for Morton's Neuroma in Adults: A Systematic Review
Authors: Edwards Steven R. , Fleming Susannah , Landorf Karl B. 
Published: September 2021

Background
Morton's neuroma is a common condition that routinely presents in podiatric practice. The aim of this study was to systematically synthesize the evidence relating to the effectiveness of a corticosteroid injection for Morton's neuroma.

Methods
Studies with a publication date of 1960 or later were eligible, and searches were performed within the Turning Research Into Practice database; the Cochrane Central Register of Controlled Trials; the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register; MEDLINE (Ovid); PubMed; Embase; Cumulative Index to Nursing and Allied Health Literature; and the gray literature. Study selection criteria included randomized and nonrandomized controlled trials where a single corticosteroid injection for Morton's neuroma pain was investigated. The primary outcome was Morton's neuroma pain as measured by any standard validated pain scale.

Results
Ten studies involving 695 participants were included. The quality of the studies was considered low and subject to bias. Of the included studies, five compared corticosteroid injection to usual care, one compared corticosteroid injection to local anesthetic alone, one compared ultrasound-guided to non–ultrasound-guided injections, three compared corticosteroid injections to surgery, one compared small to large neuromas, six assessed patient satisfaction, four measured adverse events, one studied return to work, and one examined failure of the corticosteroid injection to improve pain. Overall, these studies identified a moderate short- to medium-term benefit of corticosteroid injections on the primary outcome of pain and a low adverse event rate.

Conclusions
A single corticosteroid injection appears to have a beneficial short- to medium-term effect on Morton's neuroma pain. It appears superior to usual care, but its superiority to local anaesthetic alone is questionable, and it is inferior to surgical excision. A very low adverse event rate was noted throughout the studies, indicating the intervention is safe when used for Morton's neuroma. However, the quality of the evidence is low, and these findings may change with further research.

Published: September 2021

Fermented maize residue, a by-product of the production of fermented starch, a local weaning food and breakfast cereal for adults in Nigeria and West Africa was dried, milled into flour and utilized as a fibre source in cookies production at 0 – 30% levels of substitution. The effects of the addition of the fermented maize residue on the physical, sensory and nutritional properties on the cookie sample were investigated. Results showed spread ratio values decreased with residue flour addition, ash content and protein content and carbohydrate also showed a decrease. The crude fibre content increased with levels of replacement. The result of sensory evaluation showed equal preference among the samples. Invitro-protein digestibility showed a decrease with fermented maize residue addition. Addition of fermented maize residue to cookie production can be a viable way of utilizing the fibre rich fermented maize residue

Authors: Théodore Alla Kouadio , Marcel Ahon Gnamien , Lezin Bomisso Edson 
Published: September 2021

Our study aims at improving the nutritional quality of eggplant fruits through application of organic fertilization. The study was conducted in Bingerville (located in the south of Côte d'Ivoire and west of Abidjan city), from April to August 2019.
The work consisted in assessing, in a randomized complete block design, the effects of five manures on the biochemical parameters of Kalenda eggplant (Solanum melongena L.) fruits. The manures studied were T1: chicken manure, T2: chicken manure + plantain peel compost, T3: chicken manure + plantain peel potash, T4: plantain peel compost, T0: no fertilizer, T5 (positive control): NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4).
The results showed that fiber, protein, lipid, sodium and iron contents were not influenced by the different treatments. However, treatments T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)), T4 (plantain peel compost), T3 (chicken manure + plantain peel potash) and T2 (chicken manure + plantain peel compost) induced the highest carbohydrate and energy content of fruits. With respect to phosphorus and potassium, treatments T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)), T4 (plantain peel compost) and T3 (chicken manure + plantain peel potash) had higher phosphorus values than those of other fertilizers T2 (chicken manure + plantain peel compost), T1 (chicken manure) with an average of 27; 26.58 and 25.491 mg per 100 g FM, respectively. Plants grown on the sites fertilized with chemical treatment T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)) produced the fruits richest in potassium with an average equal to 255.16 mg per 100 g FM, followed by treatment T3 (chicken manure + plantain peel potash) (245.5 mg/100g FM). For magnesium and calcium, treatments T3 (chicken manure + plantain peel potash) and T5 (NPK (10 18 18) + Urea (46% N) + Potassium sulphate (K2SO4)) were characterized by the lowest contents, thus reflecting an antagonism between potassium and these minerals.
From this study, it appears that plantain peel applied as an organic fertilizer on eggplant is a source of potassium, phosphorus, carbohydrates and energy for a good nutritional balance of the body.
Photocatalytic Degradation of Remazol Brilliant Blue R and Remazol Yellow FG using TiO2 doped Cd, Co, Mn
Authors: Purnawan Candra , Wahyuningsih Sayekti , Aniza Oktaviani Nur , Sari Octaria Priwidya 
Published: September 2021

TiO2 and TiO2 doped Cd, Co, Mn (TiO2-M) were synthesized with a sol-gel method, and the photocatalytic activity of Remazol Brilliant Blue R and Remazol Yellow FG has been conducted. TiO2-M (Cd, Co, Mn) was synthesized with the mol Ti:M ratio of 3:1, and the materials were calcined at 300, 400, and 500 °C. The materials were characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX), and UV-Vis Reflectance. The XRD result shows that at the temperature of 300 °C TiO2 and TiO2-M formed tend to be amorphous. At 400 °C the anatase phase is formed, while at 500 °C the rutile phase begins to form. And overall, the crystallinity of TiO2 is higher than metal-doped TiO2. The UV-Vis Reflectance result showed that the bandgap energy of all doping materials (TiO2-M) decreased. The larger the metal ion radius of dopant, the larger the crystal size obtained and then the higher the bandgap obtained. The results of SEM-EDX showed that the morphology of TiO2 was spherical and regular, whereas the morphology of TiO2-M had a smoother surface due to the influence of metal doping. Photocatalytic activity of TiO2-M on Remazol Brilliant Blue R and Remazol Yellow FG was greater than TiO2. The optimum pH of the solution was obtained at pH 5 and the optimum catalyst phase was obtained at the anatase phase. The percentages degradation for 30 min of Remazol Brilliant Blue R were 67.34% (TiO2), 92.12% (TiO2-Co), 85.47% (TiO2-Mn), and 83.91% (TiO2-Cd), while for Remazol Yellow FG they were 58.84% (TiO2), 74.61% (TiO2-Co), 67.93% (TiO2-Mn) and 64.19% (TiO2-Cd), respectively.

Evaluation of action in local governments for reducing vacant houses and availability of qualitative system
Authors: Tatsukami Yasuhisa , Yokoyama Shunsuke , Tokuono Tetsu 
Published: September 2021

AbstractThis study explores practical approaches to address future vacant housing problems by investigating various support systems established by local governments in Japan. The investigation aims to clarify the components and application of such countermeasures and identify local governments that have achieved positive results after taking qualitative measures and implementing distinct policies. These countermeasures include renovation and demolition subsidies among other strategies. Budgetary limitations make such systems inflexible and the number of vacant houses under a local government’s purview difficult to determine. While some local governments have secured large budgets and designed policies with wider scopes, others with small budgets have achieved substantial successes by setting up clear visions. Each local government should prioritize key aspects of its regional challenges to design a vacant housing policy that addresses the most urgent goal achievable with a limited budget.
Extended‐state‐observer‐based dynamic surface control of flexible‐joint robot systems with input saturation
Authors: Chen Lian , Wang Qing 
Published: September 2021

SummaryThis article presents an extended‐state‐observer‐based dynamic surface control approach for flexible‐joint robot systems with asymmetric input saturation and large unknown dynamic knowledge. Traditional controllers for flexible‐joint robot systems usually use approximation technology to deal with unknown dynamics knowledge. Unlike the traditional control algorithm, this article utilizes an extended state observer to estimate the unknown dynamics. For the closed‐loop system, the delay strategy handles the time‐scale separation issue, the filtering system overcomes the “explosion of differentiation” caused by the repeated differentiation of auxiliary control signals, and the mean‐value‐theorem solves the input saturation problem of the actuator. The stability analysis implies that estimation errors of extended state observers (ESOs) and other state variables are semiglobally uniformly ultimately bounded. Compared with fuzzy control algorithms, the novel ESO‐based dynamic surface control approach not only omits online learning time but also uses only a few control parameters to obtain satisfactory tracking performance. Finally, a comparison simulation experiment is provided to illustrate the effectiveness of the gained conclusions.

Published: September 2021

AbstractPlastic‐based electronics fill the gaps in conventional rigid silicon‐based devices toward the applications in soft interfaces. However, people in the future should also consider their potential environmental impact if tons of non‐degradable plastics are applied. Silk fibroin is a superior substrate alternative for the development of “green” electronics; whereas, the brittleness of silk films is still a major limitation impeding their practical use. Different from the widely reported polyphasic composite approaches, here a trace‐ion‐assisted plasticization strategy is developed, and shape‐engineerable pure silk fibroin paper (PSFP) is prepared for the first time, which can be engraved and crumpled like a sheet of paper in the dry state. The PSFPs exhibit higher tensile fracture energy (14.4 ± 4 kJ m−2) than any typical plastic‐electronic‐substrates as far as it is known. The intrinsic brittleness of pure silk films is overcome, and the PSFP can be easily engineered to form periodic meshes, electronic prototypes, and kirigami‐based devices, which are beyond the reported regenerated silk films or silk composite films. Moreover, the scrape coating method employed here is simple, highly repeatable, and suitable for scaled production of low‐cost PSFP continuously. Collectively, the PSFP is generalizable to various shapes and devices, represents an ideal substrate alternative to plastic electronics.

Published: September 2021

Abstract2D GaSe is a semiconductor belonging to the group of post‐transition metal chalcogenides with great potential for advanced optoelectronic applications. The weak interlayer interaction in multilayer 2D materials allows the formation of several polymorphs. Here, the first structural observation of a new GaSe polymorph is reported, characterized by a distinct atomic configuration with a centrosymmetric monolayer (D3d point group). The atomic structure of this new GaSe polymorph is determined by aberration‐corrected scanning transmission electron microscopy. Density‐functional theory calculations verify the structural stability of this polymorph. Furthermore, the band structure and Raman intensities are calculated, predicting slight differences to the currently known polymorphs. In addition, the occurrence of layer rotations, interlayer relative orientations, as well as translation shear faults is discussed. The experimental confirmation of the new GaSe polymorph indicates the importance of investigating changes in the crystal structure, which can further impact the properties of this family of compounds.
Finite‐Temperature Dynamics in Cesium Lead Iodide Halide Perovskite

Published: September 2021

AbstractLattice dynamics are often regarded as signatures of the underlying crystal structure. Here, a first‐principle‐based effective Hamiltonian method combined with molecular dynamics simulations is used to study dynamical behaviors of CsPbI3 perovskite across temperature and structural phase transitions. A single (short‐range tilting) parameter in this effective Hamiltonian is varied in order to make the temperature range of the intermediate tetragonal P4/mbm phase, existing in‐between the cubic Pmm and orthorhombic Pnma phases, either broader than observed or completely disappearing. Comparing the dynamics of these different cases allows one to conclude that real CsPbI3 perovskite should have i) two iodine‐octahedral‐tilt related modes that differ in frequency but both significantly soften as the temperature decreases within the cubic phase toward the Pmm‐to‐P4/mbm transition; and ii) one mode that maintains a very low frequency (of the order of 1.0 cm−1) in the entire region of P4/mbm stability, as a result of the temporal exploration of various structural states. Such latter sub‐THz mode mixes fluctuations of antiphase iodine tiltings and Cs antipolar motions because of a trilinear energetic coupling.

Published: September 2021

AbstractElectrocatalytic reactions possess wide application prospects in solving the energy crisis. Recently, the emerging 0D carbon dots (CDs) have become potential candidate materials due to their low cost, high conductivity, easy modification, and simple synthesis. CDs‐based composite materials showcase attractive electrocatalytic performances because of the abundant active sites and charge distribution on the material surface. Considering the complicated structure of CDs, it's important to identify the specific catalytic activity source and understand catalytic mechanisms with the aid of theoretical method. In this review, the latest advancements are presented on improving the electrocatalytic activity and stability of CDs‐based composite materials from theoretical perspective. Meanwhile, the opportunity and challenges about developing high‐performance CDs catalysts are also highlighted.
