Published: December 2022

AbstractBackground and objectivesResearch suggests that fibrinogen (Fib) concentrations are used to assess the occurrence and severity of diabetic foot (DF) and to monitor the progression of diabetic foot in patients. However, its correlation with Fib function has not been reported. Here, angle α and k value, reflecting the Fib function, were used to analyse its correlation with DF, and their potential as biological indicators for evaluating the occurrence and severity of DF was explored.Subjects and methodsThis clinical study enrolled 163 type 2 diabetes mellitus (T2DM) patients, who were divided into the diabetes with DF (84 cases) group, diabetes with no DF (79 cases) group. Meanwhile, 90 healthy unrelated subjects were enrolled as controls.ResultsAngle α and fibrinogen levels increased greatly in subjects with DF compared with those without. The k value levels greatly decreased in subjects with DF compared with those without (P < 0.01). Spearman correlation analysis showed that angle α and fibrinogen were positively correlated with DF grading (r = 0.635, P < 0.01; r = 0.616, P < 0.01), k value was negatively correlated with DF (r= − 0.589, P < 0.01). ROC curve analysis showed that the optimal cut-off point for angle α to distinguish patients with DF from those without was 62.85 deg, with a sensitivity of 78.6% and specificity of 78.7%. The optimal cut-off point for k value was 1.75 min, with a sensitivity of 82.1% and specificity of 65.8%. The optimal cut-off point for fibrinogen was 3.85 g/l, with a sensitivity of 63.1% and specificity of 98.2%. The optimal cut-off point for angle α to evaluate the risk of diabetic foot progression was 70.20 deg, with a sensitivity of 73.2% and specificity of 90.7%. The optimal cut-off point for k value was 1.25 min, with a sensitivity of 67.9% and specificity of 90.8%. The optimal cut-off point for fibrinogen was 4.12 g/l, with a sensitivity of 85.7% and specificity of 93.5%.ConclusionAngle α, k-value and fibrinogen have clinical significance on the risk of occurrence and development of diabetic foot, which can contribute to early diagnosis and early clinical intervention in DF.

AbstractConsidering human decision-making is essential for understanding the mechanisms underlying the propagation of real-life diseases. We present an extension of a model for pathogen spread that considers farmers’ dynamic decision-making regarding the adoption of a control measure in their own herd. Farmers can take into account the decisions and observed costs of their trade partners or of their geographic neighbours. The model and construction of such costs are adapted to the case of bovine viral diarrhoea, for which an individual-based stochastic model is considered. Simulation results suggest that obtaining information from geographic neighbours might lead to a better control of bovine viral diarrhoea than considering information from trade partners. In particular, using information from all geographic neighbours at each decision time seems to be more beneficial than considering only the information from one geographic neighbour or trade partner at each time. This study highlights the central role that social dynamics among farmers can take in the spread and control of bovine viral diarrhoea, providing insights into how public policy efforts could be targeted in order to increase voluntary vaccination uptake against this disease in endemic areas.

Authors: Wollny Krista , Cui Sara , McNeil Deborah , Benzies Karen , Parsons Simon J. , Sajobi Tolulope , Metcalfe Amy 
Published: December 2022

Abstract
Background
An unplanned extubation is the uncontrolled and accidental removal of a breathing tube and is an important quality indicator in pediatric critical care. The objective of this review was to comprehensively synthesize literature published on quality improvement (QI) practices implemented to reduce the rate of unplanned extubations in critically ill children.

Methods
We included original, primary research on quality improvement interventions to reduce the rate of unplanned extubations in pediatric critical care. A search was conducted in MEDLINE (Ovid), Embase, and CINAHL from inception through April 29, 2021. Two reviewers independently screened citations in duplicate using pre-determined eligibility criteria. Data from included studies were abstracted using a tool created by the authors, and QI interventions were categorized using the Behavior Change Wheel. Vote counting based on the direct of effect was used to describe the effectiveness of quality improvement interventions. Study quality was assessed using the Quality Improvement Minimum Quality Criteria Set (QI-MQCS). Results were presented as descriptive statistics and narrative syntheses.

Results
Thirteen studies were included in the final review. Eleven described primary QI projects; two were sustainability studies that followed up on previously described QI interventions. Under half of the included studies were rated as high-quality. The median number of QI interventions described by each study was 5 [IQR 4–5], with a focus on guidelines, environmental restructuring, education, training, and communication. Ten studies reported decreased unplanned extubation rates after the QI intervention; of these, seven had statistically significant reductions. Both sustainability studies observed increased rates that were not statistically significant.

Conclusions
This review provides a comprehensive synthesis of QI interventions to reduce unplanned extubation. With only half the studies achieving a high-quality rating, there is room for improvement when conducting and reporting research in this area. Findings from this review can be used to support clinical recommendations to prevent unplanned extubations, and support patient safety in pediatric critical care.

m6A demethylase FTO regulate CTNNB1 to promote adipogenesis of chicken preadipocyte
Authors: Li Kan , Huang Weichen , Wang Zhijun , Nie Qinghua 
Published: December 2022

Abstract
Background
N6-methyladenosine (m6A) is an abundant post-transcriptional RNA modification that affects various biological processes. The fat mass and obesity-associated (FTO) protein, a demethylase encoded by the FTO gene, has been found to regulate adipocyte development in an m6A-dependent manner in multiple species. However, the effects of the m6A methylation and FTO demethylation functions on chicken adipogenesis remain unclear. This study aims to explore the association between m6A modification and chicken adipogenesis and the underlying mechanism by which FTO affects chicken preadipocyte development.

Results
The association between m6A modification and chicken lipogenesis was assessed by treating chicken preadipocytes with different doses of methyl donor betaine and methylation inhibitor cycloleucine. The results showed that betaine significantly increased methylation levels and inhibited lipogenesis, and the inverse effect was found in preadipocytes after cycloleucine treatment. Overexpression of FTO significantly inhibited m6A levels and promoted proliferation and differentiation of chicken preadipocytes. Silencing FTO showed opposite results. Mechanistically, FTO overexpression increased the expression of catenin beta 1 (CTNNB1) by improving RNA stability in an m6A-dependent manner, and we proved that FTO could directly target CTNNB1. Furthermore, CTNNB1 may be a positive regulator of adipogenesis in chicken preadipocytes.

Conclusions
m6A methylation of RNA was negatively associated with adipogenesis of chicken preadipocytes. FTO could regulate CTNNB1 expression in a demethylation manner to promote lipogenesis.

Abstract
Background
Recently, despite the steady decline in the tuberculosis (TB) epidemic globally, school TB outbreaks have been frequently reported in China. This study aimed to quantify the transmissibility of Mycobacterium tuberculosis (MTB) among students and non-students using a mathematical model to determine characteristics of TB transmission.

Methods
We constructed a dataset of reported TB cases from four regions (Jilin Province, Xiamen City, Chuxiong Prefecture, and Wuhan City) in China from 2005 to 2019. We classified the population and the reported cases under student and non-student groups, and developed two mathematical models [nonseasonal model (Model A) and seasonal model (Model B)] based on the natural history and transmission features of TB. The effective reproduction number (Reff) of TB between groups were calculated using the collected data.

Results
During the study period, data on 456,423 TB cases were collected from four regions: students accounted for 6.1% of cases. The goodness-of-fit analysis showed that Model A had a better fitting effect (P < 0.001). The average Reff of TB estimated from Model A was 1.68 [interquartile range (IQR): 1.20–1.96] in Chuxiong Prefecture, 1.67 (IQR: 1.40–1.93) in Xiamen City, 1.75 (IQR: 1.37–2.02) in Jilin Province, and 1.79 (IQR: 1.56–2.02) in Wuhan City. The average Reff of TB in the non-student population was 23.30 times (1.65/0.07) higher than that in the student population.

Conclusions
The transmissibility of MTB remains high in the non-student population of the areas studied, which is still dominant in the spread of TB. TB transmissibility from the non-student-to-student-population had a strong influence on students. Specific interventions, such as TB screening, should be applied rigorously to control and to prevent TB transmission among students.

An approximate travel time calculation and a robust GNSS-acoustic positioning method using an MCMC technique
Authors: Tomita Fumiaki , Kido Motoyuki 
Published: December 2022

AbstractIt is important to consider horizontal heterogeneity in an underwater sound speed structure to accurately estimate positions of GNSS-acoustic sites. Although large amounts of moving survey data (a sea-surface platform moves around when acoustic signals are transmitted) are required to accurately detect a sloping sound speed structure, the actual observational data do not necessarily include sufficient moving survey data due to sea conditions or observational time. To treat these insufficient data, it was assumed that a shallow sound speed gradient was continuously present up to a fixed water depth (gradient depth). However, the validity of this assumption has not been investigated, and the gradient depth has not been optimized. In this study, we developed a new GNSS-acoustic array positioning method that optimizes the gradient depth using an MCMC technique. To employ this technique, we also developed an approximate technique for rapidly calculating travel time, because the conventional travel time calculation requires high computational cost for integration into the MCMC technique. We assessed the performance of the approximate travel time calculation technique and demonstrated its sufficient accuracy and precision for estimating array positions. Then, we applied the new GNSS-acoustic array positioning method to the actual observational data collected by the Japan Coast Guard and Tohoku University. Using enough amounts of the moving survey data, our method demonstrated the results comparable with the conventional GNSS-acoustic positioning method estimating a sloping sound speed structure; thus, the assumption of the sound speed gradient with the fixed water depth was valid. Moreover, due to the physical restriction of this assumption, our method provided robust solutions even when the observational data contained small quantities of moving survey data with a simple sea-surface track. Although our method still cannot be used in the scenario, where no moving survey data are available, it can work robustly compared with the conventional methods.

Abstract

Background
Glioblastoma multiforme (GBM) is a fatal malignant primary brain tumor in adults. The therapeutic efficacy of chemotherapeutic drugs is limited due to the blood-brain barrier (BBB), poor drug targeting, and short biological half-lives. Multifunctional biomimetic nanodrugs have great potential to overcome these limitations of chemotherapeutic drugs.

Methods
We synthesized and characterized a biomimetic nanodrug CMS/PEG-DOX-M. The CMS/PEG-DOX-M effectively and rapidly released DOX in U87 MG cells. Cell proliferation and apoptosis assays were examined by the MTT and TUNEL assays. The penetration of nanodrugs through the BBB and anti-tumor efficacy were investigated in the orthotopic glioblastoma xenograft models.

Results
We showed that CMS/PEG-DOX-M inhibited cell proliferation of U87 MG cells and effectively induced cell apoptosis of U87 MG cells. Intracranial antitumor experiments showed that free DOX hardly penetrated the BBB, but CMS/PEG-DOX-M effectively reached the orthotopic intracranial tumor through the BBB and significantly inhibited tumor growth. Immunofluorescence staining of orthotopic tumor tissue sections confirmed that nanodrugs promoted apoptosis of tumor cells. This study developed a multimodal nanodrug treatment system with the enhanced abilities of tumor-targeting, BBB penetration, and cancer-specific accumulation of chemotherapeutic drugs by combining chemotherapy and photothermal therapy. It can be used as a flexible and effective GBM treatment system and it may also be used for the treatment of other central nervous systems (CNS) tumors and extracranial tumors.

Published: December 2022

Abstract
Background
Endovascular treatment (EVT) is an alternative option for symptomatic intracranial atherosclerotic disease (ICAD). However, the effect of EVT treatment on ICAD plaques is still unclear. This study describes the ICAD plaque characteristics after EVT treatment and analyzes the effect of different EVT treatments on plaque characteristics.

Method
From 2017 January to 2022 January, ICAD patients who underwent endovascular treatment and had follow-up high-resolution magnetic resonance image (HRMRI) were enrolled in the study. Multiple plaque characteristics, including plaque enhancement, plaque burden, were measured based on preoperative, and follow-up HRMRI. Plaque characteristics and postoperative plaque changes were analyzed between different treatment groups.

Result
Finally, 50 intracranial atherosclerotic plaques in 45 patients were included. Including 28 male patients and 17 female, media age 63.0 years old. Among 50 plaques, 41 received percutaneous angioplasty (including 22 plain balloons and 19 drug-coated balloons (DCB)) and the other 9 underwent stenting. Stenosis rate, plaque burden and eccentricity index at the lesion site were significantly decreased after EVT compared with preoperative periods (p <0.001). And only the DCB group showed a significant reduction in plaque enhancement at follow-up (p < 0.001). No significant preoperative and postoperative changes in other plaque characteristics were found.

Conclusion
EVT treatment could compromise the characteristics of intracranial periarterial atherosclerotic plaques, and DCB treatment may result in a reduction in plaque enhancement after treatment.

Published: December 2022

AbstractThe molecular platforms of the innate immune system are essential to recognize pathologic external factors that are crucial to differentiate these danger signals from host motifs. A set of sensors recognizing pathologic factors is present and defined as a membrane-bound family of Toll-like receptors as well as the cytosolic ones including the family of nucleotide-binding domain leucine-rich repeat proteins. In this regard, the inflammasomes have been identified as an innate immune sensor toward pathologic external factors as well as endogenous damage-associated molecular pattern signals transducing from the above-mentioned receptors to gene expressions. Recent research has shown novel findings in inflammasome biology and genetics which lead to the alteration of diagnosis and management in autoinflammatory diseases as well as developing novel treatments, including the examples of nucleotide-binding domain leucine-rich repeat proteins-inflammasomes and pyrin-inflammasomes. The pyrin protein is encoded by the Mediterranean Fever gene on chromosome 16 that acts as a major regulatory component of the inflammasome, and is responsible for familial Mediterranean fever. We have recently examined the whole nucleotide sequence of the Mediterranean Fever gene in Japanese familial Mediterranean fever patients and revealed single nucleotide variants associated with the susceptibility of familial Mediterranean fever from a nation-wide survey by the next-generation sequencing. In a cytokine profile analysis of familial Mediterranean fever patients, we have found that interleukin-6 is considered to be one of the most crucial cytokines in familial Mediterranean fever attack since interleukin-6 had the best performance for distinguishing familial Mediterranean fever in attack from healthy controls or familial Mediterranean fever in remission, and in vitro interleukin-6 production is regulated by microRNAs-204-3p/phosphoinositide 3-kinase g pathway. Accordingly, we have been investigating the efficacy and safety of anti-human interleukin-6 receptor monoclonal antibody, tocilizumab, in patients with familial Mediterranean fever refractory or intolerant to colchicine through an investigator-initiated clinical trial supported by the Japan Agency for Medical Research and Development. Like interleukin-1b, interleukin-18 can be processed by caspase-1 and proteinase-3 to be activated within the inflammasomes. We have also found the importance of interleukin-18 in several autoinflammatory conditions. Recently, the concept of autoinflammation is widely distributed into many common diseases; thus, the attention to a wide spectrum of diseases MEFV gene deeply involved is required.

Published: December 2022

Abstract
Background
The war against malaria in Africa especially Sub-Saharan Africa seems to be unending despite all efforts being invested on it for some decades. Mosquitoes have remained key transmitters of malaria. This study evaluated the larvicidal potentials of ethanolic leaf extracts of Cymbopogon citratus, Ricinus communis and Allium sativum on the fourth instar larvae of Anopheles mosquito.

Results
Cymbopogon citratus had the highest mortality of 78% (312) out of 400 larvae used in all the varied concentrations (100, 200, 300, 400 and 500 mg/l), and had the least LC50 value of 54.08 mg/l. Ricinus communis and Allium sativum had mortalities of 59.75% (239) and 73.75% (295) with LC50 of 141.25 mg/l and 81.096 mg/l, respectively. There was no mortality in the control. Temperature, pH and conductivity correlated positively with mortality (p < 0.05) while dissolved oxygen and total dissolved solids did not positively correlate with mortality (p > 0.05).

Conclusions
Ethanolic leaf extracts of Cymbopogon citratus, A. sativum and R. communis have larvicidal properties. However, C. citratus was most effective followed by A. sativum while R. communis was the least effective. The extracts of these plants can serve as replacements to synthetic insecticides because they are bio-degradable, ecologically friendly, safe for non-target organisms and do not lead to an aftermath problem and still have properties that can reduce pest populations.

Published: December 2022

Abstract
Background
There are several studies which have studied large cohort of Neuro-Bechet’s disease (NBD) patients worldwide However, there is sparse literature about NBD from India. We aimed to characterize the clinical, radiological characteristics, treatment response and outcome in NBD.

Methods
The study was a retrospective descriptive analysis of a cohort of patients with NBD evaluated between January 2017 to June 2021, fulfilling the International Consensus Recommendation (ICR) criteria for NBD.

Results
Twelve patients were diagnosed as NBD during the study period. The mean age of the patient was 34.7 ± 11.1 (range 21–59 years). The mean duration of illness was 1.4 ± 1.2 years. All 12 patients had neuroparenchymal NBD. Systemic symptoms were present in 6 patients (50%). Pyramidal tract involvement (67%) was the most common symptom and sign followed by cranial nerve, spinal cord and visual involvement. Pathergy test was positive in 6 patients (50%). Human leucocyte antigen (HLA) B51 positivity was seen in all patients. Thalamus (100%) was the most common area involved followed by pons (80%). Favourable outcome (modified Rankin Scale scores ≤ 2) was seen in 7 patients, poor outcome in 3 patients and 2 patients were lost to follow-up after first attack.

Conclusion
NBD is prevalent in India and there is need for clinical suspicion. Brainstem and cerebral syndrome are the most common presentation of NBD and thalamus is the most common site of involvement in NBD.
