Published: March 2022

Abstract
Background: Nontraumatic spontaneous renal hemorrhage is caused by tumor such as renal cell carcinoma or angiomyolipoma in most cases. Vasculitis including periarteritis nodosa or antineutrophil cytoplasmic antibody (ANCA)-mediated vasculitis may also be the next underlying background. Herein, we report the first case of nontraumatic spontaneous bilateral renal hemorrhage combined with chronic infection of Chlamydia pneumoniae.Case presentation: The patient serially suffered from left and right back pain within 78 days due to bilateral spontaneous renal hemorrhages. Transcatheter arterial embolization was successfully performed twice to treat serial spontaneous bilateral renal hemorrhages. The serological examination apparently revealed his chronic infection of Chlamydia pneumoniae and a slight elevation of anti-deoxy nucleotide antibodies. Furthermore, computed tomography (CT) angiogram and 67galium citrate scintigram also suggested underlining severe arteriosclerosis without severe inflammation in bilateral kidneys. Chronic infection of Chlamydia pneumoniae and underlying autoimmune vasculitis may pull a trigger of bilateral spontaneous renal hemorrhages although the real mechanisms remain unknown. Conclusions: In conclusion, we reported an extremely rare case of nontraumatic spontaneous bilateral renal hemorrhage of unknown etiology. Severe atherosclerosis caused by chronic infection due to Chlamydia pneumoniae may predispose to the vascular vulnerability of the bilateral renal arteries in close association with hypertension, oral intake of antiplatelets, and underlying autoimmune vasculitis.

Abstract
The objective of this study was to obtain the 24-h precipitation frequency estimates for return periods of 1-1000 years in Shaoguan, South China, to provide scientific suggestions for flood disaster warning and urban flood control planning. Annual Maximum Precipitation (AMP) respectively from observational rainfall and Integrated Multi-satellitE Retrievals for GPM (IMERG) gridded rainfall which can supplement precipitation information in areas without rain gauges was used for the calculation of estimates using Regional L-Moments Analysis (RLMA) method. Then the quantiles at grids were corrected by Mean Bias Correction (MBC) method with the estimates at sites. The results showed that there has more and stronger extreme precipitation in the northwest of Shaoguan. The number of homogeneous regions as well as the spatial distribution of parameters (Cv , Cs and Ck) for two datasets is different. When the return periods are larger than 100 years, the estimates at sites are also larger than that at grids and the difference will increase as return period increases. After modified, the quantiles from IMERG are more reasonable and combine the spatial distribution characteristic of estimates from two cases, which indicates that the rainstorm high-risk area of Shaoguan is in the southwest to the central, as well as in the west-central.

A study on the effects of plasma spraying parameters on the adhesion strength of Cr3C2-NiCr coating on 16Mn steel
Authors: Thao Dang Xuan , Duc Cuong Pham 
Published: March 2022

This paper experimentally studied the adhesion strength of Cr3C2-30 %NiCr coating created on 16Mn steel substrate by plasma thermal coating technique in relation to spraying parameters. Experiments were carried out according to the central composite design (CCD) experimental matrix with three parameters: current intensity, powder feeding rate, and spray distance. Samples consisting of an annular disc and a latch made of 16Mn were fabricated according to the JIS H8664-1977 standard. Cr3C2-30 %NiCr coating was then created on the top surface of the disc including end of the latch. Adhesion strength of the coating to the substrate was measured through the tensile test. ANOVA analysis of variance was performed to evaluate the influence of the spraying parameters on adhesion strength and to build an empirical regression function representing the relationship between those parameters and the adhesion. Optimization problem was solved by ANOVA method and genetic algorithm (GA) to determine the value of the spraying parameters at which the coating has the greatest adhesion strength to the substrate. The results showed that the spraying parameters greatly affected the adhesion of the Cr3C2-30 %NiCr coating to the 16Mn substrate. Among them the spray distance has the greatest influence while the powder feeding rate has the least. Secondly, the regression function was well reflected the relationship between the three parameters and adhesion strength of the coating on the substrate. Using the values of spray parameter obtained from the GA optimization to create Cr3C2-30 %NiCr coating on 16Mn steel, the adhesion strength of the coating to the substrate reached a value of 98.4 % compared to the prediction
Development of spreadsheet simulation models of gas cylinders inventory management
Authors: Gribanova Ekaterina , Mitsel Artur , Shilnikov Alexandr 
Published: March 2022

The solution of the problem of managing the inventory of an enterprise whose activities are related to the purchase and sale of gas cylinders is considered. To solve the problem, it was necessary to investigate and choose the best inventory management strategy that provides the minimum value of the average inventory balance in the warehouse with the established upper limit of the average deficit. The problem of determining the best strategy is presented as a discrete programming problem, the required variables of which depend on the replenishment method. With a periodic replenishment strategy, the controlled variables are the volume of the delivery line and the delivery interval, with a threshold one, the minimum inventory level and the volume of the delivery line. Let’s also consider replenishment with a predicted inventory level, where the delivery level and the minimum inventory level are used as control variables. Three tabular simulation models with a given delivery time and random demand are proposed. Using the Chi-square test, it was found that the quantity demanded has a normal distribution law. By carrying out computational experiments, the optimal values of controlled variables were determined. The best objective function values were obtained using a model with a predicted inventory level and a threshold replenishment strategy. Experiments conducted on the basis of historical data have shown the advantage of the two model strategies compared to the strategy currently used in the enterprise. The use of a model with a predictable inventory level would reduce the average inventory balance by 46 %, and, consequently, save working capital. The results of the study can be useful for managers of enterprises whose activities are related to inventory management
Analysis of the crystal structure of the Ba3TeO6 compound
Authors: Zavodyannyi Viktor 
Published: March 2022

The object of research is the crystal structure of the Ba3TeO6 compound. It is known from the literature that this material has photoluminescent properties and crystallizes in the tetragonal system with the space symmetry group I41/a (88) and lattice periods a=19.3878 А; b=19.3878 Аº, c=34.909 Аº. At the same time, there are data on two other polymorphic modifications of this compound, which are in the PDF-2 database for 2009. Therefore, information about the crystal structure of this compound is incomplete. The existence of different spectra for a given compound mentioned in the literature may be due to different methods of synthesis of this compound. A study of the crystal structure of the compound Ba3TeO6 under the number 00-035-0995 in the PDF-2 database for 2009 is proposed.
The study used the 2009 PDF-2 database. As well as the HighScorePlus 3.0 program (Netherlands), which makes it possible to refine the microstructural parameters of a structural model using the Rietveld method.
The diffraction spectrum for the study was generated using the HighScorePlus 3.0 program and the 2009 pdf-2 database connected to it in UDF format.
As a result, it was found that this diffraction spectrum of the studied compound can correspond to the following structural model: orthorhombic system with lattice periods a=4.2910 A; b=4.4062 A; c=4.3459 A. The space symmetry group Pnnn(48) is possible.
Analyzing the results obtained, it should be recognized that the studied structure of the compound crystallizes in its own structural type. At the same time, the crystal structures of the polymorphic modifications of this compound are similar.
The study of the crystal structure of the compound contributes to a better understanding of its physical properties, in particular, photoluminescence
High performance epoxy/ MWCNTs nanocomposite sensors for multi-purpose sensing in structural health monitoring
Authors: Bouhamed Ayda , Sun Xin , Kanoun Olfa 
Published: March 2022

Structural health monitoring (SHM) is necessary for modern technical development. It can be achieved by detecting different quantities such as pressure and strain using highly sensitive and stable sensors. In this work, epoxy/multiwalled carbon nanotubes (MWCNTs) is used as sensing material to detect both strain and pressure. To ensure better performance, dispersion fabrication process was firstly optimized via electrical and microscopic measurements. Then, the piezoresistive performance such as the sensitivity, linearity, stability and drift were investigated under pressure and strain for films prepared with different carbon nanotubes (CNTs) concentration and thickness to define the optimal conditions for each sensing target.
The piezoresistive measurement shows good sensitivity to strain at very low CNTs concentration 0.3 wt. % with a gauge factor (GF = 11.094); which is around 6 times higher than conventional strain sensor, proving the efficiency of the optimized fabrication process parameters that ensure a homogenous distribution. Furthermore, the sensing layer shows also the ability to sustain high pressure load. The sensitivity is found to be highly dependent on the film thickness with higher sensitivity for thicker films in case of pressure sensing in addition to the good sensitivity at very low-pressure range. All these results prove the efficiency of Epoxy/MWCNTs as multi-purpose sensor material.

Published: March 2022

Background
The quality of care in labor and delivery is traditionally measured through the Hospital Consumer Assessment of Healthcare Providers and Systems but less is known about the experiences of care reported by patients and caregivers on online sites that are more easily accessed by the public.

Objective
The aim of this study was to generate insight into the labor and delivery experience using hospital reviews on Yelp.

Methods
We identified all Yelp reviews of US hospitals posted online from May 2005 to March 2017. We used a machine learning tool, latent Dirichlet allocation, to identify 100 topics or themes within these reviews and used Pearson r to identify statistically significant correlations between topics and high (5-star) and low (1-star) ratings.

Results
A total of 1569 hospitals listed in the American Hospital Association directory had at least one Yelp posting, contributing a total of 41,095 Yelp reviews. Among those hospitals, 919 (59%) had at least one Yelp rating for labor and delivery services (median of 9 reviews), contributing a total of 6523 labor and delivery reviews. Reviews concentrated among 5-star (n=2643, 41%) and 1-star reviews (n=1934, 30%). Themes strongly associated with favorable ratings included the following: top-notch care (r=0.45, P<.001), describing staff as comforting (r=0.52, P<.001), the delivery experience (r=0.46, P<.001), modern and clean facilities (r=0.44, P<.001), and hospital food (r=0.38, P<.001). Themes strongly correlated with 1-star labor and delivery reviews included complaints to management (r=0.30, P<.001), a lack of agency among patients (r=0.47, P<.001), and issues with discharging from the hospital (r=0.32, P<.001).

Conclusions
Online review content about labor and delivery can provide meaningful information about patient satisfaction and experiences. Narratives from these reviews that are not otherwise captured in traditional surveys can direct efforts to improve the experience of obstetrical care.
Business Process Model and Notation and openEHR Task Planning for Clinical Pathway Standards in Infections: Critical Analysis
Authors: Iglesias Natalia , Juarez Jose M , Campos Manuel 
Published: March 2022

Background
Clinical pathways (CPs) are usually expressed by means of workflow formalisms, providing health care personnel with an easy-to-understand, high-level conceptual model of medical steps in specific patient conditions, thereby improving overall health care process quality in clinical practice. From a standardized perspective, the business process model and notation (BPMN), a widely spread general-purpose process formalism, has been used for conceptual modeling in clinical domains, mainly because of its easy-to-use graphical notation, facilitating the common understanding and communication of the parties involved in health care. However, BPMN is not particularly oriented toward the peculiarities of complex clinical processes such as infection diagnosis and treatment, in which time plays a critical role, which is why much of the BPMN clinical-oriented research has revolved around how to extend the standard to address these special needs. The shift from an agnostic, general-purpose BPMN notation to a natively clinical-oriented notation such as openEHR Task Planning (TP) could constitute a major step toward clinical process improvement, enhancing the representation of CPs for infection treatment and other complex scenarios.

Objective
Our work aimed to analyze the suitability of a clinical-oriented formalism (TP) to successfully represent typical process patterns in infection treatment, identifying domain-specific improvements to the standard that could help enhance its modeling capabilities, thereby promoting the widespread adoption of CPs to improve medical practice and overall health care quality.

Methods
Our methodology consisted of 4 major steps: identification of key features of infection CPs through literature review, clinical guideline analysis, and BPMN extensions; analysis of the presence of key features in TP; modeling of relevant process patterns of catheter-related bloodstream infection as a case study; and analysis and proposal of extensions in view of the results.

Results
We were able to easily represent the same logic applied in the extended BPMN-based process models in our case study using out-of-the-box standard TP primitives. However, we identified possible improvements to the current version of TP to allow for simpler conceptual models of infection CPs and possibly of other complex clinical scenarios.

Conclusions
Our study showed that the clinical-oriented TP specification is able to successfully represent the most complex catheter-related bloodstream infection process patterns depicted in our case study and identified possible extensions that can help increase its adequacy for modeling infection CPs and possibly other complex clinical conditions.
A Mobile App for Children With Asthma to Monitor Indoor Air Quality (AirBuddy): Development and Usability Study
Authors: Kim Sunyoung , Stanton Kaitlyn , Park Yunoh , Thomas Stephen 
Published: March 2022

Background
Indoor air quality is an important environmental factor that triggers and exacerbates asthma, the most common chronic disease in children. A mobile app to monitor indoor air quality could help occupants keep their indoor air quality clean. However, no app is available that allows children to monitor and improve their indoor air quality.

Objective
Previously, we conducted a series of user-centered design studies to identify user needs and design requirements toward creating a mobile app that helps children with asthma to engage in monitoring and improving indoor air quality as part of their asthma management. Based on the findings from these studies, we created AirBuddy, a child-friendly app that visualizes air quality indoors and outdoors.

Methods
This paper reports on the findings from a field deployment with 7 pediatric asthma patients, where we evaluated AirBuddy’s usability and usefulness in real-world settings by conducting weekly semistructured interviews for 8 weeks.

Results
All participants positively responded to the usefulness and usability of AirBuddy, which we believe is thanks to the iterative, user-centered design approach that allowed us to identify and address potential usability issues early on and throughout the design process.

Conclusions
This project contributes to the field of mHealth app design for children by demonstrating how a user-centered design process can lead to the development of digital devices that are more acceptable and relevant to target users’ needs.
Men’s Health Research in New Zealand: A Scoping Review
Authors: Xiao Hui , Doolan-Noble Fiona , Liu Lizhou , White Alan , Baxter G. David 
Published: March 2022

Background: Globally, there has been a growing awareness of the health challenges faced by men. The current public health agenda in Aotearoa New Zealand (NZ) does not specifically address the needs of men. The aim of this scoping review was to capture the major health issues facing men in NZ and particularly to identify the knowledge gaps in the understanding of men’s health within the NZ context. This was achieved by presenting key data on their health status and systematically mapping research in NZ related to men’s health; international data are also referenced for context as relevant. Method: A search and screening of the literature were conducted using Ovid, Web of Science and Scopus databases from January 1996 to July 2021, with advice from a medical librarian. Search terms included “men’s/male’s health” and “men’s/male’s health NZ.” An environmental scan of international literature was also carried out and information from the Ministry of Health and Statistics NZ was obtained to provide context of the status of research on men’s health in NZ. Main Findings: In keeping with international literature, the major health issues for men in NZ are life-limiting diseases including cancer and cardiovascular disease, the spread of overweight and obesity, issues with masculinity and help-seeking behaviours, unhealthy lifestyles, mental health issues and poor health literacy. The main areas of research related to men’s health from the NZ literature were highlighted. Discussion: Men’s health remains an under-recognised issue in NZ. If we are to address current inequities in health for men, clinicians, researchers and relevant agencies need to pay more attention to men’s health issues and take up the challenge to highlight and promote men’s health status in NZ.
EjCaM7 and EjCAMTA3 synergistically alleviate chilling-induced lignification in loquat fruit by repressing the expression of lignin biosynthesis genes under cold stress

Published: March 2022

Flesh lignification is a typical chilling injury (CI) symptom of loquat
fruit during cold storage.
[Calcium](D:/D%E7%9B%98/Youdao/Dict/8.9.9.0/resultui/html/index.html) [chloride](D:/D%E7%9B%98/Youdao/Dict/8.9.9.0/resultui/html/index.html)
(CaCl ) could enhance chilling tolerance in loquat
fruit, but the molecular mechanism is still not illuminated. In this
study, CaCl treatment suppressed the increase in
firmness and lignin content, and retained higher extractable juice,
thereby alleviating chilling-induced lignification in loquat fruit.
Moreover, CaCl enhanced the
[calmodulin](javascript:;) (CaM) content, free Ca
distribution, EjCaM7, and CaM binding
transcription activators 3 ( EjCAMTA3) expression in loquat fruit
during cold storage, indicating Ca /CaM-CAMTA played
a key role in response to cold stress. The EjCAMTA3 and EjCaM7 proteins
were identified and characterized from loquat fruit. Importantly,
EjCAMTA3 bound to the CG-box in EjPODP7-like and
EjLAC12-like promoters to repress their transcription. Further
analysis revealed that EjCaM7 interacted with EjCAMTA3 in a Ca
-dependent manner, and this interaction enhanced the
EjCAMTA3-mediated transcriptional repression of EjPODP7-like and
EjLAC12-like genes. Taken together, these findings suggested that
CaCl treatment alleviates chilling-induced
lignification in loquat fruit, which probably via the synergistic role
of EjCaM7 and EjCAMTA3 in the modulation of EjPODP7-like and
EjLAC12-like genes expression, leading to the repression of
lignin polymerization.
