Combining Accelerometer and GPS Features to Evaluate Community Mobility in Knee Ankle Foot Orthoses (KAFO) Users

Orthotic and assistive devices such as knee ankle foot orthoses (KAFO), come in a variety of forms and fits, with several levels of available features that could help users perform daily activities more naturally. However, objective data on the actual use of these devices outside of the research lab is usually not obtained. Such data could enhance traditional lab-based outcome measures and inform clinical decision-making when prescribing new orthotic and assistive technology. Here, we link data from a GPS unit and an accelerometer mounted on the orthotic device to quantify its usage in the community and examine the correlations with clinical metrics. We collected data from 14 individuals over a period of 2 months as they used their personal KAFO first, and then a novel research KAFO; for each device we quantified number of steps, cadence, time spent at community locations and time wearing the KAFO at those locations. Sensor-derived metrics showed that mobility patterns differed widely between participants (mean steps: 591.3, SD =704.2). The novel KAFO generally enabled participants to walk faster during clinical tests (<inline-formula> <tex-math notation="LaTeX">$\Delta 6$ </tex-math></inline-formula>Minute-Walk-Test=71.5m, p=0.006). However, some participants wore the novel device less often despite improved performance on these clinical measures, leading to poor correlation between changes in clinical outcome measures and changes in community mobility (<inline-formula> <tex-math notation="LaTeX">$\Delta 6$ </tex-math></inline-formula>Minute-Walk-Test – <inline-formula> <tex-math notation="LaTeX">$\Delta $ </tex-math></inline-formula>Community Steps: r=0.09, p=0.76). Our results suggest that some traditional clinical outcome measures may not be associated with the actual wear time of an assistive device in the community, and obtaining personalized data from real-world use through wearable technology is valuable.
Influence of zinc and boron on biochemical and yield characteristics of sunflower

Effect of Zinc (Zn) and Boron (B) application was studied on biochemical and quality parameters and yield in sunflower (Helianthus annuus L.). The study revealed that combined application of Zn (5.25 kg/ha) and B (6.3 kg/ha) was most effective followed by Zn (5.25 kg/ha) or B (2.1 kg/ha). The combination showed increase over the control in chlorophyll content, nitrogen content in dry matter and seed, phosphorus content in dry matter and seed, potassium content in dry matter and seed, and oil and protein content in seed. Similarly, the combined application of Zn and B exhibited increase over control in straw yield, harvest index, translocation efficiency, 100-seed weight and seed yield per plant.
99mTc-DPD scintigraphy in immunoglobulin light chain (AL) cardiac amyloidosis

Abstract Aims Technetium-99m-labelled 3,3-diphosphono-1,2-propanodicarboxylic acid (99mTc-DPD scintigraphy) is recognized as highly accurate for the non-invasive diagnosis of transthyretin (ATTR) cardiac amyloidosis (CA). A proportion of patients with immunoglobulin light chain (AL) CA have also been reported to show cardiac 99mTc-DPD uptake. Herein, we assessed the frequency and degree of cardiac 99mTc-DPD uptake and its clinical significance among patients with AL CA. Methods and results Between 2010 and 2017, 292 consecutive patients with AL CA underwent 99mTc-DPD scintigraphy and were included in this study: 114 (39%) had cardiac 99mTc-DPD uptake: grade 1 in 75%, grade 2 in 17%, and grade 3 in 8% of cases. Patients with cardiac 99mTc-DPD uptake had poorer cardiac systolic function and higher N-terminal pro-brain natriuretic peptide. No differences were noted in cardiac magnetic resonance parameters between patients with and without cardiac 99mTc-DPD uptake (N = 19 and 42, respectively). Patients with cardiac 99mTc-DPD uptake showed a trend to worse survival than those with no uptake (log-rank P = 0.056). Among 22 patients who underwent serial 99mTc-DPD scintigraphy, 5 (23%) showed reduction in the grade of cardiac uptake. Conclusions In this large cohort of patients with AL CA, 99mTc-DPD scintigraphy ∼40% of cases showed cardiac uptake, including grade 2–3 in 10% of all patients (25% of those with cardiac 99mTc-DPD uptake). Cardiac 99mTc-DPD uptake was associated with poorer cardiac function and outcomes. These data highlight the critical importance of ruling out AL amyloidosis in all patients with cardiac 99mTc-DPD uptake to ensure such patients are not assumed to have ATTR CA.
Healthcare workers` knowledge level regarding anaphylaxis and usage of epinephrine auto-injectors.

BACKGROUND Inadequate practices in diagnosis and management of anaphylaxis in parallel with an increase in its prevalence may cause serious public health problems today. This is the first study aiming to assess the theoretical knowledge of professional and non-professional healthcare workers from different lines of the healthcare service chain about anaphylaxis management, and their practice approaches for epinephrine autoinjectors (EAIs) together. METHODS The study included 697 participants comprising physicians, dentists, pharmacists, and school staff. In face-to-face interviews, each participant was asked to fill out the questionnaire forms prepared for assessing their demographic characteristics, experience with a case of anaphylaxis and EAI and theoretical knowledge about the diagnosis and treatment of anaphylaxis, and to demonstrate how to use EAI in practice with trainer device. RESULTS The rates of 391 physicians, 98 dentists, 102 pharmacists and 105 school staff of knowing the diagnosis criteria of anaphylaxis were 47.6%, 31.6%, 31.1%, 19%, and knowing the first and life-saving treatment of anaphylaxis were 87.2%, 79.6%, 47.6%, 15.2%, respectively. Predictors that affected physicians in knowing the first and life-saving treatment of anaphylaxis were having experience with EAIs [OR:5.5, (%95CI:1.330-23.351, p=0.015)] and a case of anaphylaxis [OR:2.4, (%95CI:1.442-4.020, p=0.001)], and knowing the administration route of epinephrine correctly [OR:1.9, (%95CI:1.191-3.314, p=0.008)]. 31.1% of the participants demonstrated the EAI usage correctly. The EAI usage steps with the most errors were `Place the appropriate injection tip into outer thigh/Press the trigger so it `clicks`` and `Turn the trigger to arrow direction` (60.3% and 34.9%, respectively). CONCLUSIONS Healthcare workers` knowledge level regarding anaphylaxis management and ability to use EAIs correctly are not adequate. That most errors were made in the same steps of EAI usage indicates that the industry should continue to strive for developing the ideal life-saving device.
Rehydration and restoration of fingerprint ridge detail in mummified post‐mortem tissue: Literature review and investigation of a simplified formulation

Mummified tissue presents challenges for fingerprinting due to rigidity, shrinkage, and other features obscuring epidermal ridge detail. A new cost‐effective in‐house solution was developed to obtain good quality fingerprints from mummified remains. The simplified procedure uses a sodium carbonate:sodium acetate mixture easily prepared using commonly available chemical products. An overview of the methods and solutions utilized to date for rehydration and restoration illustrates the main benefits of the developed formulation: the solution provided better tissue pliability and turgor than the sodium carbonate:ethanol formulation of Rüffer previously employed; the prepared solution proved stable for weeks at room temperature and poses minimum hazard risk to users. It functions as a weak base (pH 9.3) and is sufficiently corrosive to allow tissue softening over a flexible timeframe of 1–5 days without causing any damage. The degree of effectiveness for rehydration of mummified tissue and restoration of ridge detail is attributed to three synergistic aspects: increased turgor as provided by a penetrating humectant and water; softening and pliability as a result of pH and any specific chemical interaction that affects calcium in collagen; ridge detail definition as a function of turgor and softening, with some secondary corrosive dependency related to the pH of a solution.
Pharmacokinetics of Polymyxin B in Hospitalized Adults with Cystic Fibrosis

The optimal polymyxin B dosage needed to achieve an efficacy target of 50 to 100 mg · h/liter when treating multidrug-resistant bacterial infections in adult cystic fibrosis (CF) patients is unclear. The pharmacokinetics of intravenous polymyxin B were evaluated to better inform dosing. ABSTRACT The optimal polymyxin B dosage needed to achieve an efficacy target of 50 to 100 mg · h/liter when treating multidrug-resistant bacterial infections in adult cystic fibrosis (CF) patients is unclear. The pharmacokinetics of intravenous polymyxin B were evaluated to better inform dosing. This was a prospective, observational pharmacokinetic (PK) study of nine CF adults receiving intravenous polymyxin B as part of usual clinical care. Doses preceding PK sampling ranged from 50 to 100 mg every 12 h. Five PK samples were collected following the fourth or fifth dose and concentrations of polymyxin subcomponents B1 and B2 were quantified using liquid chromatography mass spectrometry (LC-MS). Population PK (NONMEM software) analysis was performed using pooled polymyxin B1+B2 concentrations. Participants were Caucasian, predominantly male, with mean age and weight of 31 years (range 21 to 57 years) and 58.0 kg (range 38.3 to 70.4 kg), respectively. A 1-compartment zero-order infusion and linear elimination model adequately described the data with estimated clearance and volume of distribution being 2.09 liters/h and 12.7 liters, respectively, corresponding to a 4.1 h mean half-life (t1/2). Although body weight was observed to influence the volume of distribution, a fixed dose of 75 mg every 12 h was predicted to achieve the target steady-state exposure. Neurotoxicities were reported in all patients, with acute kidney injury events in two patients. These events resolved within 2 to 4 days after discontinuing polymyxin B. Fixed maintenance dosing of polymyxin B without loading is predicted to achieve the targeted therapeutic exposure in CF adults. Treatment-limiting neurotoxicities are very common in this population.
Acute Delta 9‐tetrahydrocannabinol administration differentially alters the hippocampal opioid system in adult female and male rats

Our prior studies demonstrated that the rat hippocampal opioid system can undergo sex‐specific adaptations to external stimuli that can influence opioid‐associated learning processes. This opioid system extensively overlaps with the cannabinoid system. Moreover, acute administration of Δ9Tetrahydrocannabinoid (THC), the primary psychoactive constituent of cannabis, can alter cognitive behaviors that involve the hippocampus. Here, we use light and electron microscopic immunocytochemical methods to examine the effects of acute THC (5 mg/kg, i.p., 1 h) on mossy fiber Leu‐Enkephalin (LEnk) levels and the distribution and phosphorylation levels of delta and mu opioid receptors (DORs and MORs, respectively) in CA3 pyramidal cells and parvalbumin dentate hilar interneurons of adult female and male Sprague–Dawley rats. In females with elevated estrogen states (proestrus/estrus stage), acute THC altered the opioid system so that it resembled that seen in vehicle‐injected females with low estrogen states (diestrus) and males: (1) mossy fiber LEnk levels in CA2/3a decreased; (2) phosphorylated‐DOR levels in CA2/3a pyramidal cells increased; and (3) phosphorylated‐MOR levels increased in most CA3b laminae. In males, acute THC resulted in the internalization of MORs in parvalbumin‐containing interneuron dendrites which would decrease disinhibition of granule cells. In both sexes, acute THC redistributed DORs to the near plasma membrane of CA3 pyramidal cell dendrites, however, the dendritic region varied with sex. Additionally, acute THC also resulted in a sex‐specific redistribution of DORs within CA3 pyramidal cell dendrites which could differentially promote synaptic plasticity and/or opioid‐associated learning processes in both females and males.
A multinomial modelling approach to face identity recognition during instructed threat

ABSTRACT To organise future behaviour, it is important to remember both the central and contextual aspects of a situation. We examined the impact of contextual threat or safety, learned through verbal instructions, on face identity recognition. In two studies (N = 140), 72 face–context compounds were presented each once within an encoding session, and an unexpected item/source recognition task was performed afterwards (including 24 new faces). Hierarchical multinomial processing tree modelling served to estimate individual parameters of item (face identity) and source memory (threat or safety context) as well as guessing behaviour. Results show that language was highly effective in establishing threatening and safe context conditions. In Study 1, a fleeting picture stream (1 s per picture) led to poor item and source recognition. Prolonged presentation times (Study 2 with 6 s per picture) improved face memory but no contextual modulation was observed. Thus, incidental face learning was surprisingly poor and rapidly changing contextual settings might have interfered with the accurate encoding of face identity information and item–source binding.
Individual Postprandial Glycemic Responses to Diet in n-of-1 Trials: Westlake N-of-1 Trials for Macronutrient Intake (WE-MACNUTR)

ABSTRACT Background The role of different types and quantities of macronutrients on human health has been controversial, and the individual response to dietary macronutrient intake needs more investigation. Objectives We aimed to use an ‘n-of-1’ study design to investigate the individual variability in postprandial glycemic response when eating diets with different macronutrient distributions among apparently healthy adults. Methods Thirty apparently healthy young Chinese adults (women, 68%) aged between 22 and 34 y, with BMI between 17.2 and 31.9 kg/m2, were provided with high-fat, low-carbohydrate (HF-LC, 60–70% fat, 15–25% carbohydrate, 15% protein, of total energy) and low-fat, high-carbohydrate (LF-HC, 10–20% fat, 65–75% carbohydrate, 15% protein) diets, for 6 d wearing continuous glucose monitoring systems, respectively, in a randomized sequence, interspersed by a 6-d wash-out period. Three cycles were conducted. The primary outcomes were the differences of maximum postprandial glucose (MPG), mean amplitude of glycemic excursions (MAGE), and AUC24 between intervention periods of LF-HC and HF-LC diets. A Bayesian model was used to predict responders with the posterior probability of any 1 of the 3 outcomes reaching a clinically meaningful difference. Results Twenty-eight participants were included in the analysis. Posterior probability of reaching a clinically meaningful difference of MPG (0.167 mmol/L), MAGE (0.072 mmol/L), and AUC24 (13.889 mmol/L·h) between LF-HC and HF-LC diets varied among participants, and those with posterior probability >80% were identified as high-carbohydrate responders (n = 9) or high-fat responders (n = 6). Analyses of the Bayesian-aggregated n-of-1 trials among all participants showed a relatively low posterior probability of reaching a clinically meaningful difference of the 3 outcomes between LF-HC and HF-LC diets. Conclusions N-of-1 trials are feasible to characterize personal response to dietary intervention in young Chinese adults.
History and current situation of neoadjuvant treatment for locally advanced esophageal cancer

Esophageal cancer is one of the most commonly diagnosed malignant tumors, especially in north China. Surgery is one of the major treatments. However, for locally advanced cases, surgery alone does not achieve an ideal prognosis. As a result of rapid development in recent years, neoadjuvant chemotherapy, neoadjuvant radiotherapy or neoadjuvant chemoradiotherapy followed by surgery are becoming the “standard treatment pattern” for patients with locally advanced esophageal cancer, and an improvement in prognosis is evident. With the gradual application of immunotherapy in esophageal cancer, neoadjuvant immunotherapy has also shown an important role. This article mainly focuses on the history and current status of neoadjuvant treatment and its future role in the treatment of esophageal cancer.
Contribution of PER-Type and NDM-Type β-Lactamases to Cefiderocol Resistance in Acinetobacter baumannii

Cefiderocol (FDC) is a recently developed siderophore cephalosporin showing excellent antibacterial activity against Gram-negative bacteria, including Acinetobacter baumannii. By investigating a series of A. baumannii clinical isolates with elevated MICs of FDC, we showed that PER-like β-lactamases and, to a lesser extent, NDM-like β-lactamases, significantly contributed to reduced susceptibility to that antibiotic. ABSTRACT Cefiderocol (FDC) is a recently developed siderophore cephalosporin showing excellent antibacterial activity against Gram-negative bacteria, including Acinetobacter baumannii. By investigating a series of A. baumannii clinical isolates with elevated MICs of FDC, we showed that PER-like β-lactamases and, to a lesser extent, NDM-like β-lactamases, significantly contributed to reduced susceptibility to that antibiotic. Interestingly, we showed that combination of FDC with avibactam exhibited excellent activity against all multidrug-resistant isolates coproducing OXA-23 and PER-type β-lactamases.
gen3sis: A general engine for eco-evolutionary simulations of the processes that shape Earth’s biodiversity

Understanding the origins of biodiversity has been an aspiration since the days of early naturalists. The immense complexity of ecological, evolutionary, and spatial processes, however, has made this goal elusive to this day. Computer models serve progress in many scientific fields, but in the fields of macroecology and macroevolution, eco-evolutionary models are comparatively less developed. We present a general, spatially explicit, eco-evolutionary engine with a modular implementation that enables the modeling of multiple macroecological and macroevolutionary processes and feedbacks across representative spatiotemporally dynamic landscapes. Modeled processes can include species’ abiotic tolerances, biotic interactions, dispersal, speciation, and evolution of ecological traits. Commonly observed biodiversity patterns, such as α, β, and γ diversity, species ranges, ecological traits, and phylogenies, emerge as simulations proceed. As an illustration, we examine alternative hypotheses expected to have shaped the latitudinal diversity gradient (LDG) during the Earth’s Cenozoic era. Our exploratory simulations simultaneously produce multiple realistic biodiversity patterns, such as the LDG, current species richness, and range size frequencies, as well as phylogenetic metrics. The model engine is open source and available as an R package, enabling future exploration of various landscapes and biological processes, while outputs can be linked with a variety of empirical biodiversity patterns. This work represents a key toward a numeric, interdisciplinary, and mechanistic understanding of the physical and biological processes that shape Earth’s biodiversity.
Accuracy of a markerless motion capture system for postural ergonomic risk assessment in occupational practice

Established methods for postural ergonomic risk assessment in occupational practice are mostly time-consuming and need to be conducted by experts. Use of technology could improve postural ergonomic risk assessments with regard to time efficiency and accuracy. A study was conducted to assess the accuracy of a markerless motion capture system (Microsoft Kinect V2) compared to a marker-based motion capture system (Vicon Bonita). Angles of different body segments were analysed. The results show major inaccuracies of the markerless motion capture system for capturing axial trunk rotation (mean angular deviation of 14.04°) indicating that potential health risks could be underestimated. Combined working postures of axial trunk rotation and arm anteversion show issues with self-occlusion. Based on the findings, it is discussed whether the detected inaccuracies for axial trunk rotation are likely to lead to overestimation or underestimation of potential health risks when conducting an ergonomic risk assessment.
Production of xylitol by Saccharomyces cerevisiae using waste xylose mother liquor and corncob residues

Exorbitant outputs of waste xylose mother liquor (WXML) and corncob residue from commercial‐scale production of xylitol create environmental problems. To reduce the wastes, a Saccharomyces cerevisiae strain tolerant to WXML was conferred with abilities to express the genes of xylose reductase, a xylose‐specific transporter and enzymes of the pentose phosphate pathway. This strain showed a high capacity to produce xylitol from xylose in WXML with glucose as a co‐substrate. Additionally, a simultaneous saccharification and fermentation (SSF) process was designed to use corncob residues and cellulase instead of directly adding glucose as a co‐substrate. Xylitol titer and the productivity were, respectively, 91.0 g l‐1 and 1.26 ± 0.01 g l‐1 h‐1 using 20% WXML, 55 g DCW l‐1 delignified corncob residues and 11.8 FPU gcellulose‐1 cellulase at 35° during fermentation. This work demonstrates the promising strategy of SSF to exploit waste products to xylitol fermentation process.
Dopamine controls whether new declarative information updates reactivated memories through reconsolidation

Consolidation and reconsolidation are independent memory processes. Consolidation stabilizes new memories, whereas reconsolidation restabilizes memories destabilized when reactivated during recall. However, the biological role of the destabilization/reconsolidation cycle is still unknown. It has been hypothesized that reconsolidation links new information with reactivated memories, but some reports suggest that new and old memories are associated through consolidation mechanisms instead. Object-recognition memory (ORM) serves to judge the familiarity of items and is essential for remembering previous events. We took advantage of the fact that ORM consolidation, destabilization, and reconsolidation can be pharmacologically dissociated to demonstrate that, depending on the activation state of hippocampal dopamine D1/D5 receptors, the memory of a novel object presented during recall of the memory of a familiar one can be formed via reconsolidation or consolidation, but only reconsolidation can link them. We also found that recognition memories formed through reconsolidation can be destabilized even if indirectly reactivated. Our results indicate that dopamine couples novelty detection with memory destabilization to determine whether a new recognition trace is associated with an active network and suggest that declarative reminders should be used with caution during reconsolidation-based psychotherapeutic interventions.
