Operational Sustainability of the Firm The operational performance versus financial solvency binomial-OPFS

This article presents the research results that assess a firm’s operational sustainability by combining the Degree of Operating Leverage (DOL) with the Current Liquidity Ratio (CLR) to present the Operational Performance versus Financial Solvency (OPFS) binomial, using a non-parametric model. The combination of the DOL with the CLR identifies metrics that indicate that a firm operates at full installed capacity and injects synergy at the generation of financial assets. The model was tested with data from standardized financial statements from 48 firms distributed among 6 sectors of the Brazilian economy, from 2007 to 2017. The results obtained suggest that, when a firm operates at full installed capacity, the DOL varies between 1 and 2, and the CLR is higher than the DOL. From the 6 sectors contemplated by the sample, 4 stand out by operating at full installed capacity with the CLR higher than the DOL, and 2 sectors signal some idleness with the DOL above 2 and the CLR lower than the DOL, such as the Public Utilities Sector (PU) indicating the highest efficiency among all. These results are relevant to illustrate that the combination of the DOL with the CLR is robust enough to evaluate a firm’s operational sustainability. Key-words: Operational Performance versus Financial Solvency, nominal payment capacity, degree of operating leverage (DOL), firm’s operational sustainability.

Synthesis and Evaluation of Ca-doped Sr2Fe1.5Mo0.5O6-δ as Symmetrical Electrodes for High Performance Solid Oxide Fuel Cells

A series of Ca-substituted Sr2Fe1.5Mo0. 5O6–δ oxides, Sr2–xCaxFe1.5Mo0. 5O6–δ (SCFMO, x=0, 0.2, 0.4 and 0.6), were synthesized and evaluated as potential electrodes for symmetrical solid oxide fuel cells. X-ray diffraction examination showed that all samples maintained cubic perovskite structure in both air and wet hydrogen atmospheres. Temperature programmed reduction measurements indicated that the Ca substitution promoted the catalytic activity of SCFMO toward oxygen evolution reactions. Symmetrical anode fuel cell measurements showed the lowest polarization resistance in humidified hydrogen emerged at x=0.6. Single cells-SC0.6FMO|La0.9Sr0. 1Ga0.8Mg0.2O3(LSGM)|SC0.6FMO, fabricated via tape-casting and impregnation methods, produced peak power densities of 1.05 W·cm at 800 °C and 0.41 W·cm at 650 °C when operating on hydrogen fuels and air oxidants. These results demonstrate SC0.6FMO is a potential electrode material for symmetrical solid oxide fuel cells.

Health-related quality of life of patients bearing diabetes mellitus

Objective: The purpose of this study was to investigate the health-related quality of life and clinical parameters of patients with type 2 diabetes mellitus. Methods: This is a cross-sectional study with a quantitative approach, which was undertaken with 73 patients with type 2 diabetes mellitus in a health unit of the Sistema Único de Saúde (SUS) [Brazilian Unified Health System] in Ribeirão Preto city, São Paulo State, Brazil, in 2016. The DQOL-Brazil questionnaire, which covers the domains of satisfaction, impact, social and/or vocational concerns, and concerns about diabetes mellitus, was used for data collection. Results: Most of the participants were female, married, and retired with an average age of 62.7 years old. The domain of vocational and/or social concerns had the best score for quality of life while satisfaction had the worst. The quality of life of patients with altered glycated hemoglobin levels was worse than that of patients without such alterations. For those with unchanged hemoglobin glycated levels, the domain of social and/or vocational concerns had the best quality of life scores while the domain of satisfaction had the worst. Conclusion: The results can help the development of intervention studies and strategic plans in health services.
Comparison of Supraspinatus Muscle Architecture During Three Different Shoulder Strengthening Exercises Using Ultrasonography

Background: Strengthening the supraspinatus is an important aspect of a rehabilitation program for subacromial impingement and tendinopathy. Many authors recommended empty-can (EC), full-can (FC), and prone full-can (PFC) exercises to strengthen the supraspinatus. However, no ultrasonography study has yet investigated supraspinatus muscle architecture (muscle thickness; MT, pennation angle; PA, fiber bundle length; FBL) in relation to supraspinatus strengthening exercises. Objects: The purpose of this study was to compare the architecture (MT, PA, and FBL) of the supraspinatus muscle during three different types of exercises (EC, FC, and PFC) using diagnostic ultrasound. Methods: Participants performed three different exercises: (A) EC; the arm was maintained at abduction with full internal rotation in the sitting position, (B) FC; the arm was maintained at abduction with full external rotation in the sitting position, and (C) PFC; the arm was maintained at abduction with full external rotation in the prone position. Ultrasonography was used to measure the MT, PA and FBL of the supraspinatus. One-way repeated analysis of variance with Bonferroni's post-hoc test was used to compare between the three exercises and the initial position of each exercise. Results: Compared with each initial position, the FC exercise showed the greatest mean difference in muscle architecture properties and the PFC exercise showed the least mean difference. Conclusion: The findings suggest that the FC exercise position may have an advantage in increasing the amount of contractile tissue or producing muscle power and the PFC exercise position may be useful in a rehabilitation program because it offers the advantage of maintaining the muscle architecture properties.
Histopathologic alterationsof gill tissue in Siluriformes and Characiformes from the Middle Tocantins River in the Brazilian Amazon

The Tocantins-Araguaia basin, the largest located entirely in Brazil, consists of three stretches along its course: the upper, middle and lower Tocantins River. According to a current survey conducted, there is no information on fish health in the Middle Tocantins River, and this area has been classified as a high priority for biodiversity conservation by Ministry of the Environment Decree 5.092 of May 21, 2004 (Brasil, 2004). 
Biochemical and Clinical Effects of Selenium on Dimethylhydrazine-induced Colon Cancer in Rats1

The biochemical and clinical effects of selenium (Na2SeO3) on 1,2-dimethylhydrazine (DMH)-induced colon carcinogenesis in male Sprague-Dawley rats are presented. A 4-ppm se lenium supplement to the drinking water was provided before, during, and after 20 weekly injections of 20 mg DMH per kg body weight. Immediately after the 20th DMH injection, part of the rats were sacrificed. The incidences of colon tumors in groups provided selenium before DMH, before and during DMH, and only during DMH treatment were reduced to 39, 43, and 36%, respectively. The incidence in the DMH only control was 63%. Other rats in all treated and control groups were maintained up to 5 months post-DMH treatment. At 10-week intervals throughout the study, selected blood and tissue com ponents were analyzed. The following hematological changes correlated with DMH treatment, (a) Serum glutamic oxalacetic transaminase increased 2-fold (normal, 66 Â± 14 g/dl). (o) Serum alkaline phosphatase increased 24% (normal, 166 Â± 56 units/liter), (c) Serum protein decreased 14% (normal, 6.77 Â±0.48 g/dl). (d) White blood count increased 2- to 3-fold (normal, 7.7 Â±2.7 x 103/cu mm). And (e) hemoglobin de creased 67% (normal, 18.1 Â± 1.3 g/dl). The magnitude of these changes varies with each selenium treatment group and with each 10-week analysis period. Provision of 4 ppm sele nium doubled both liver and blood selenium levels compared to unsupplemented controls. The effects of selenium and DMH treatments on glutathione peroxidase and /i-glucuronidase ac tivities and on sialic acid are presented. Possible mechanisms by which selenium protects against DMH-induced neoplasia are discussed. DMH treatment, with colon tumor development, and with the effect of selenium on DMH-induced carcinogenesis.
Open science practices in general and internal medicine journals, an observational study

Background As part of the Open Science movement, this study aims to analyze the current state of open access and open data policies concerning the availability of articles and raw data of the journals belonging to the category “Medicine, General & Internal” of the Science Citation Index Expanded. Methods Journal data sharing policies were evaluated through the following variables: possibility of manuscript storage in repositories; reuse policy; publication on a website; and statement regarding complementary material. Subsequently, an analysis of the supplementary material associated with each article was performed through the PubMed Central repository. The study reported was assessed following the STROBE guidelines for observational studies. Results This study shows that only one-third of the journals included in the category “Medicine, General & Internal” allow the depositing of their documents in repositories and its reuse, while approximately half of the journals agree to publish the document on a website as well as to deposit supplementary material along with the publication. However, the reality about this last variable is that only 9.5% of the articles analyzed contained supplementary material being the main journals involved, BMJ Open, JAMA Network Open, New England Journal of Medicine, Lancet and Plos Medicine. Conclusions The analysis of the opening policies of the journals concerning data availability in medical research reveals the unequal positioning of publishers towards the sharing of open data, the ambiguity regarding government policies about the obligation to deposit data and the need for ethical and standardization requirements in the typology/format of the data deposited without forgetting the important role that the researcher plays. Further studies based on journals indexed in medical databases other than Science Citation Index Expanded are needed.
Predictors of personality disorders in prisoners

Personality disorders can lead to difficult social or occupational functional processes rooted in chronic maladaptive thoughts, feelings, and behaviors. This study aimed to investigate factors of personality disorder in prisoners from the central prison of Sanandaj, Iran. We conducted a cross-sectional study, which included all prisoners in the central prison of Sanandaj, Iran. The study sample includes 343 prisoners, of which 329 were male, and 14 were female, selected by randomized multistage sampling method. Participants filled in Millon's multi-axis clinical questionnaire. The data were analyzed using Chi-square, multiple logistic regression, and bootstrap analysis. There were 183 participants without personality disorders (53.4%) and 99 participants (28.9%) with cluster B personality disorders (narcissistic, histrionic, anti-social, and borderline). Male gender (OR=0.07) and elementary education level (OR=0.18) have a significant relationship with cluster A personality disorders (paranoid, schizoid, schizotypal). Cluster B has a significant relationship only with the elementary education level (OR=0.27). Cluster C (avoidant, dependent, obsessive-compulsive personality disorder) has a significant relationship with male gender (OR=0.20), elementary education level (OR=0.30), unemployment (OR=2.64), theft crime types (OR=0.38) and disputes and assaults (OR=0.18). Based on these results, psychological and psychiatric interventions in prisoners are suggested.
Intelligent Performance Evaluation of Urban Subway PPP Project Based on Deep Neural Network Model

Neural network refers to an algorithmic mathematical model that imitates the behavioral characteristics of animal neural networks and performs distributed information processing. This kind of network depends on the complexity of the system and needs to adjust the internal node relationship, so as to achieve the purpose of processing information. With the continuous development of the economy, the transportation problem needs to be solved urgently, and the urban subway has emerged at the historic moment. The subway is a fast, large-capacity, electric-driven rail transit built in the city. The advantages of the subway provide conditions for the mitigation of urban traffic, due to the large number of cars, traffic jams, frequent accidents, and serious environmental pollution. In the city center, there are more cars and less space, and the parking lot is not commensurate with the number of cars, making parking difficult. This paper aims to study the intelligent performance evaluation of urban subway PPP projects based on deep neural network models. The subway project has a large investment, a long period, and a wide range, but the development time of the subway in China is relatively short. In order to promote the stable progress of subway projects, it is very necessary to conduct intelligent performance evaluation on subway projects. This paper compares and analyzes the basic characteristics of the PPP model and verifies the applicability and necessity of the PPP model in urban subway transportation projects. Through the investigation of relevant literature, this article puts forward the research content of the social impact assessment of subway projects. The experimental results of this paper show that, from the perspective of whether it is necessary to evaluate the performance of PPP projects, 65% of people think it is very necessary, and 22% think it is more necessary. 3% of people think it is unnecessary, and 10% of people hold an indifferent attitude. These data show that the intelligent performance evaluation of urban subway PPP projects has exploratory significance for urban infrastructure design and construction.
Role and Effectiveness of Intra-articular Injection of Hyaluronic Acid in the Treatment of Knee Osteoarthritis: A Systematic Review

Osteoarthritis (OA) is a degenerative joint disease that causes persistent joint pain and stiffness of mainly the large peripheral weight-bearing joints. It is a leading cause of functional disability and poor quality of life. Various modalities of therapy are recommended by different research organizations at different stages of OA including non-pharmacological, pharmacological, and surgical interventions. Intra-articular injections of hyaluronic acid (HA) is widely used for over three decades in the treatment of OA. However controversies exist regarding its safety and efficacy, the number of injections and courses, type of preparation, duration of its effects, and combining it with other drugs or molecules. This study aimed to review the most recent data available in the published literature to address these. Electronic databases like Medline, Embase, ProQuest, and Google Scholar were searched for articles using keywords, intraarticular injections, hyaluronic acid, and osteoarthritis knee. The review was carried out as per PRISMA guidelines. Thirty-eight randomized control trials (RCTs) investigating the efficacy and safety of intra-articular injection of HA were included in the systematic review. Out of the 38 studies, 22 (57.9%) were double-blind, eight (21%) single-blind, three (7.9%) non-blind, four (10%) with simple randomization, and one (2.7%) was open-labeled. Total 5,025 patients were included in these studies. The mean age of the patients was 60.28 years and the osteoarthritis grade of the knee joint was 1 to 3. HA was studied as a test preparation in 19 (50%) while in another 19 (50%) it was studied as a control. In 24 (63.2%) studies, HA was used as high molecular weight preparation in eight (21%) as low molecular weight preparation while in six studies the information was not available. HA was used as a standalone preparation in 31 studies, in two studies it was injected with platelet-rich plasma (PRP) and with either low-level laser therapy (LLLT), triamcinolone (TA), betamethasone (CS), poly deoxyribonucleotide (PDRN) or dexamethasone (DX) in one study each. In the majority of the studies, HA was given as a single injection (52.6% studies) or weekly three injections (28.9% studies). In 13.2 %, it was given as weekly 5 injections and in 5.3% as weekly two injections. IA-HA injections have a limited role in the treatment of knee osteoarthritis in those patients who do not have sufficient pain relief with topical or oral medication and physical therapy. It is safe and effective except for minor side effects such as local pain and swelling lasting for a few days. Severe allergic reactions are extremely rare. They provide adequate pain relief and functional improvement for up to six months irrespective of a number of injections and type of preparations used. The combination formulations with corticosteroids or PRP or MSCs show better results than HA alone. Combining HA with newer molecules such as peptides or diclofenac for sustained and disease-modifying effects requires more studies in the future.
Planning for Maternity Waiting Home Bed Capacity: Lessons from Rural Zambia

Background: Maternity waiting homes (MWH) allow pregnant women to stay in a residential facility close to a health center while awaiting delivery. This approach can improve health outcomes for women and children. Health planners need to consider many factors in deciding the number of beds needed for an MWH. Objective: The objective of the study is to review experience in Zambia in planning and implementing MWHs, and consider lessons learned in determining optimal capacity. Methods: We conducted a study of 10 newly built MWH in Zambia over 12 months. For this case study analysis, data on beds, service volume, and catchment area population were examined, including women staying at the homes, bed occupancy, and average length of stay. We analyzed bed occupancy by location and health facility catchment area size, and categorized occupancy by month from very low to very high. Findings: Most study sites were rural, with 3 of the 10 study sites rural-remote. Four sites served small catchment areas (<9 000), 3 had medium (9 000–11 000), and 3 had large (>11 000) size populations. Annual occupancy was variable among the sites, ranging from 13% (a medium rural site) to 151% (a large rural-remote site). Occupancy higher than 100% was accommodated by repurposing the MWH postnatal beds and using extra mattresses. Most sites had between 26–69% annual occupancy, but monthly occupancy was highly variable for reasons that seem unrelated to catchment area size, rural or rural-remote location. Conclusion: Planning for MWH capacity is difficult due to high variability. Our analysis suggests planners should try to gather actual recent monthly birth data and estimate capacity using the highest expected utilization months, anticipating that facility-based deliveries may increase with introduction of a MWH. Further research is needed to document and share data on MWH operations, including utilization statistics like number of beds, mattresses, occupancy rates and average length of stay.
Acceptance and Attitude of Parents Regarding COVID-19 Vaccine for Children: A Cross-Sectional Study

Background The coronavirus disease 2019 (COVID-19) pandemic has claimed millions of lives worldwide. India also launched a COVID-19 vaccination drive, and clinical trials for a pediatric COVID-19 vaccine are in development. Objectives The study aims to assess the acceptance and attitude of parents regarding the COVID-19 vaccine for children in India. The study also aims to find the association between selected demographic variables and acceptance and attitudes in parents regarding the COVID-19 vaccine for children. Materials and methods We conducted a cross-sectional descriptive study with 204 participants, and data were collected online using Google Forms. The study participants were parents of children aged two to 15 years. A self-structured tool was used to assess parents' acceptance regarding vaccinating their children, and a modified vaccination attitudes examination scale was used to assess parents' attitudes toward pediatric vaccination against COVID-19. We used IBM SPSS Statistics for Windows, Version 20.0 (IBM Corp., Armonk, New York) to analyze the data. Demographic data were represented as frequency and percentage. Binary logistic regression analysis was used to determine the associations between sociodemographic data and parents' levels of acceptance and attitude. For all the data, p<0.05 was considered significant. Results The majority of the participants (85%) reported acceptance of the COVID-19 vaccine for children. More than 80% of parents agree that vaccines are essential to halt the COVID-19 pandemic and are mandatory for children. Most parents (62%) also believed that complementary medicine is better than vaccines for children. While most parents (95%) reported trusting the vaccine, but more than half (59%) reported concerns regarding the unknown future effects of the vaccine. Mothers (odds ratio (OR), 2.963; p=0.015) and parents of children who received routine vaccination (OR, 0.175; p=0.039) were willing to vaccinate their children when a COVID-19 vaccine became available. Mothers (OR, 3.294; p=0.002) and respondents whose family member or close relative suffered from COVID-19 (OR, 0.420; p=0.029) accepted the COVID-19 vaccine irrespective of the child's age. Study participants who had previously tested positive for COVID-19 (OR, 0.275; p=0.012) believed vaccines for children were necessary to halt the COVID-19 pandemic. Conclusion We sought to assess parents' acceptance and attitudes regarding the COVID-19 vaccine for children in India. According to our results, while parents have a high acceptance of a pediatric COVID-19 vaccine, they also have a few apprehensions. Therefore, for a successful mass vaccination drive among the pediatric age group, there should be rigorous communication regarding the vaccine and staunch health campaigns to create more awareness and acceptance toward the COVID-19 vaccine for children.
