The usefulness of quantitative 99mTc-HMPAO WBC SPECT/CT for predicting lower extremity amputation in diabetic foot infection

We investigated the usefulness of quantitative 99mTc-white blood cell (WBC) single photon emission computed tomography (SPECT)/computed tomography (CT) for predicting lower extremity amputation in diabetic foot infection (DFI). A total of 93 feet of 83 consecutive patients with DFI who underwent WBC SPECT/CT for treatment planning were retrospectively analysed. The clinical and SPECT/CT parameters were collected along with the measurements of the maximum standardized uptake value (SUVmax) at DFI. Statistical logistic regression analysis was performed to explore the predictors of LEA and receiver operating characteristic (ROC) curve was analysed to assess the predictive value of SPECT/CT. The independent predictors of amputation were previous amputation (OR 11.9), numbers of SPECT/CT lesions (OR 2.1), and SUVmax of DFI; either continuous SUVmax (1-increase) (OR 1.3) or categorical SUVmax > 1.1 (OR 21.6). However, the conventional SPECT/CT interpretation failed to predict amputation. In ROC analysis, the SUVmax yielded a fair predictor (area under the curve (AUC) 0.782) of amputation. The model developed from these independent predictors yielded an excellent performance for predicting amputation (AUC 0.873). Quantitative WBC SPECT/CT can provide new information useful for predicting the outcomes and guiding treatment for patients with DFI.

The impact of open access on citations, Pageviews, and downloads: a scientometric analysis in Postgraduate Medical Journal.

The influence of Open Access (OA) on the citation impact of scholarly articles remains a topic of considerable debate. This study aims to elucidate the relationship between OA publication and citation metrics, as well as article visibility, within the context of the Postgraduate Medical Journal (PMJ). We conducted a retrospective analysis of 373 articles published in PMJ between 2020 and 2021. Data on OA status, citations, page views, PDF downloads, and other relevant variables were extracted from Journal Citation Reports and PMJ's official website. Multivariable linear regression and other statistical analyses were used to assess the impact of OA on these metrics. OA articles (n = 78) demonstrated significantly higher citation counts, page views, and PDF downloads compared with subscription-based articles (n = 295). Specifically, OA articles showed a significant increase in citation frequency with a β coefficient of 25.08 and a 95% CI of 17.168-32.992 (P < .001). Similarly, OA status was independently associated with increases in page views [β = 288.636, 95%CI: 177.749-399.524, P < .001] and PDF downloads [β = 118.966, 95%CI: 86.357-151.575, P < .001]. Strong correlations among total citations, page views, and PDF downloads were observed in both OA and subscription articles. The study highlights a significant and independent association of OA publishing with increased citation counts, page views, and PDF downloads in PMJ, suggesting that OA articles have broader reach and greater visibility. Further research, including randomized controlled studies across various journals, is needed to confirm these findings and explore the full impact of OA publishing.

Predictors of severe hepatotoxicity among retroviral infected adults on HAART regimen in Ilubabor Zone, Southwest Ethiopia

Nearly half of the deaths among hospitalized human immuno deficiency virus-infected patients in the highly active antiretroviral therapy era have been attributed to liver disease. This may range from an asymptomatic mild increase of liver enzymes to cirrhosis and liver failure. Different works of literature elucidated both retroviral infection and the adverse effects of highly active antiretroviral therapy as a cause of hepatotoxicity. Individual adaptations to medications and environmental exposures, shaped by cultural norms and genetic predispositions, could potentially modulate the risk and progression of liver disease in this population. Therefore, this study aims to assess the predictors of severe hepatotoxicity in retroviral-infected adults receiving highly active antiretroviral therapy regimens within the Ilubabor Zone, Southwest Ethiopia. A facility-based cross-sectional study was conducted among adult retroviral-infected patients in five selected anti-retro virus therapy clinics from May1 to July 30/2022. A systematic sampling technique was used to select 457 study participants and Binary logistic regression statistical data analysis was used, P value < 0.05 was considered statistically significant. The prevalence of severe hepatotoxicity was 21.44% in the study population. CD+4 count < 200 cells/mm3 (AOR = 2.19, 95% CI 1.04–5.22, P = 0.01), human immunodeficiency virus co-infection with tuberculosis (AOR = 2.82, 95% CI 1.01–8.29, P = 0.03) and human immuno deficiency virus co-infection with hepatitis-B/hepatitis C virus (AOR = 5.02, 95% CI 1.82–16.41) were predictors of severe hepatotoxicity. The magnitude of severe hepatotoxicity was high among adult retroviral-infected patients on highly active anti-retroviral drug regimens. Co-infection of human immuno deficiency virus with hepatitis B virus or hepatitis C virus, tuberculosis and CD4+T-cell count below 200 cells/mm3 were predictors of severe hepatotoxicity. Therefore, HIV patients on highly active antiretroviral therapy require close attention and regular monitoring of their liver function.

The Risk of Oral Cancer and the High Consumption of Thermally Processed Meat Containing Mutagenic and Carcinogenic Compounds.

The International Agency for Research on Cancer has classified the consumption of heat-processed meat as a direct human carcinogen and the consumption of red meat as a probable carcinogen. Mutagenic and carcinogenic compounds present in meat dishes include, among others, polycyclic aromatic hydrocarbons (PAHs) and heterocyclic aromatic amines (HAAs). These compounds can cause the development of gastrointestinal cancer. Oral cancer is one of the world's research priorities due to the ever-increasing incidence rate. However, the effect of diet on oral cancer is still a poorly recognized issue. The aim of this study was to assess the relationship between the risk of oral cancer and dietary ingredients with a particular emphasis on red meat and thermally processed meat. This study was conducted among patients with oral cancer in 2022 and 2023. The shortened standardized Food Frequency Questionnaire (FFQ) and a multivariate regression statistical analysis were used. The high consumption of red meat in general and thermally processed meat, especially smoked, fried, roasted and boiled, increases the risk of oral cavity cancer. Limiting the consumption of meat products and modifying the methods of preparing meat dishes may reduce exposure to carcinogenic compounds from the diet and thus reduce the risk of developing oral cancer.

Background and Purpose: This study was conducted in line with the request of the senior management of a hospital. The objective of the current research is to identify managerial problems through the relationship between health employees' perceptions of organizational justice, trust in the manager and the organization, and job satisfaction; develop a solution proposal over the relationships between these variables and motivation variables; and present a model proposal (BUY Model) as a result. Methods: The study sample is comprised of 673 employees. The study data were collected online using a questionnaire consisting of five scales. The data were analyzed by descriptive statistical methods, correlation analysis, and regression analysis. Results: The findings obtained from the study showed that the participants' perceptions of organizational justice, trust in the manager and the organization, job satisfaction and motivation were generally at a moderate level. The study also determined that trust in the manager and the organization had a partial mediation effect on the effect of organizational justice on job satisfaction and the variables of trust in the organization, organizational justice, and trust in the manager, respectively, and especially, the job satisfaction variable also affected motivation. Conclusion: The BUY model was developed to identify problems related to the management of healthcare human resources and solve these problems. Considering the importance of the concepts of job satisfaction and motivation in terms of employee performance, health service quality, and patient satisfaction, it is thought that the developed model will benefit managers of health institutions in increasing the job satisfaction and motivation levels of health employees.

The amount of drunk days and its relationships with other characteristics of alcoholic behavior of the respondents

Introduction Alcohol abuse is a multifaceted problem. Its harmful effects on the individual have been more studied. Less studied is the influence of a drinking person on his microsocial environment. Having an abusing person in his space makes it interesting to study the influence of some quantitative and qualitative indicators of his alcohol consumption on the microsocial environment.Objectives1532 people were examined during 2018-2022, who belonged to three comparison groups: patients with alcohol dependence (AD) (401 people); healthy relatives of AD patients (725 people); representatives of the general population comparable with the representatives of the first two age groups (406 people).MethodsThe main research instruments were the questionnaire of the international research consortium “GENAHTO” (Gender, Alcohol, and Harms to Others), as well as the Alcohol Use Disorders Identification Test (AUDIT). The obtained data were processed by methods of mathematical statistics (variance, correlation and regression analysis).Results An algorithm for regression analysis in conditions of high dispersion of the initial data has been developed. Using this algorithm, it was shown that the regression dependence of the main characteristics of alcohol behavior on the frequency of DD is non-linear, while for typical and maximum doses of alcohol it is optimally described by polynomials of the second degree, and for the severity of disorders due to alcohol use (AU), the time spent on AU, as well as self-assessment of the negative impact of AU by respondents on their environment - by polynomials of the third degree. It was found that for men (on average) to reach the border of risky-dangerous AU (according to the criteria of the AUDIT test), a lower frequency of DD is sufficient than for women, which indicates a greater vulnerability of men (compared to women) to the formation of disorders due to AU.ConclusionsIt was established that for men (on average) to reach the limit of risky and dangerous (according to the criteria of the AUDIT test), a lower frequency (2-3 times a week) is enough than for women (3-4 times a week), which once again indicates greater vulnerability of men (compared to women) to the formation of due to psychological problems and mental disorders.Disclosure of InterestNone Declared

Resistance pattern observed in community-acquired urinary tract infection in children from a tertiary care hospital situated in a tribal district of eastern India

ABSTRACT Background: Community-acquired urinary tract infection (CA-UTI) is mostly treated empirically. There are limited studies on pediatric UTIs, their microbiological profile, and resistance patterns. Antimicrobial resistance and even multidrug resistance are on the rise among uropathogens in the pediatric population and may lead to complications in the long run. This study was done to know the microbiological profile and the resistance pattern of CA-UTI in the pediatric population of a tertiary care hospital in a tribal district of northern Odisha among children aged 5–14 years. Methods: A hospital-based cross-sectional study was done from January 2021 to June 2021. All cases aged between 5 and 14 years attending the pediatrics outpatient department suspected of UTI were included. Descriptive statistical analysis and regression analysis were done using the statistical software Stata SE 13. Results: Out of the total 311 cases, vomiting and pain in the abdomen were the most common clinical presentations. Significant bacterial growth was isolated in 74 samples. Escherichia coli (39.2%) was the predominant isolate. Resistance to cefotaxime (38.2%) and ciprofloxacin (36.4%) is highest and seen in both gram-positive and negative bacteria. Multidrug resistance was detected in 33.7% of the bacterial isolates. Conclusion: The present study highlights the problem of the rising resistance pattern of common bacterial pathogens causing CA-UTI in children. Further studies on genotypic resistance and appropriate measures are required to prevent the rapidly spreading resistance among these common uropathogens.

Differences in the Role of Psychological Well-Being and Subjective Well-Being in Predicting Work Engagement

Employees with high Work Engagement (WE) are believed to be more reliable in achieving organizational goals. This research aims to determine the differences in the role of well-being with the concepts of hedonic and eudemonic in predicting WE. The subjects of this research consisted of 327 people, who were analyzed in 3 stages, namely 110 people who were analyzed in stage-1, 217 people who were analyzed in stage-2, and all research subjects were analyzed in stage-3. All data for this research were collected using the WE scale, PWB scale, SWFL scale, and PANAS, which have a Chronbach alpha reliability coefficient of .773 respectively; .831; .627; 747; 744. In stage-1 research analysis, SWB and PWB show more of just one component, whereas in stage-2 and stage-3 research analysis, they are more likely to be seen as two different factors in predicting WE. The results of the stepwise model multiple regression statistical technique analysis concluded that the regression coefficient on the influence of SWB and PWB on WE from the three analyses stated that PWB was stronger than SWB in predicting WE. Thus, it can be interpreted that to predict WE the Well-Being concept with the eudemonic concept is greater than using well-being with the hedonic concept.

Operational risk estimation using system analysis methodology

Financial risks are considered today as popular research topics due to the existing practical necessity for the use of their mathematical models, estimates of possible loss in many areas of human activities, forecasting, and respective managerial decisions in financial and other spheres where capital, obligations, stocks, bonds, and other activities are circulating successfully. Financial processes today exhibit sophisticated forms of evolution in time that require the application of sophisticated modeling, risk estimating, forecasting, and decision-making/support methods, techniques, and procedures. The system analysis approach is applied to solving such problems as a unique and universal research methodology. The financial risks, specifically the operational ones in the study considered, are classified as nonlinear and nonstationary processes that require appropriate methods for analysis and a rather sophisticated analytical description to estimate and forecast possible loss. The results of operational risk analysis are achieved in the form of systemic methodology, models constructed with statistical data, regression analysis, and Bayesian techniques, and estimated loss with the models. The models and system analysis approach proposed for analyzing financial processes are suitable for practical applications, provided the users have appropriate statistical data and expert estimates.

Business responsibility and government complicity in environmental conflicts: a quali-quantitative analysis of global patterns

ABSTRACT Our paper aims at widening political ecology research on business’ responsibility and public governance conditions in cases of violation of Environmental-related Human Rights (ERs), by adopting a quantitative perspective. We focused on a subset of socio-environmental conflicts (SECs) that directly connect with the violations of ERs. We propose a quali-quantitative analysis to explore the country distribution of the incidence of violations of ERs leading to SECs (VERCs) worldwide; the extent to which these can be associated with the involvement of business companies; and the general governance conditions spatially associated with the emergence of VERCs, regardless of the involvement of businesses. Through statistical regression analysis, we showed that the evidence of business’ implication in VERCs and of the lack of adequate public governance conditions suggest the need to complexify our perspective with a more nuanced understanding of the patterns of liability and complicity between diverse actors involved in SECs.

It investigates the historical evolution of exchange rate regimes in both countries, analyzing their unique policy objectives. Using empirical analysis, the research explores the correlation between exchange rates and stock market indices, employing statistical methods and regression analysis to identify patterns. Comparative assessments reveal distinct patterns in stock market performance, shedding light on the effectiveness of different exchange rate systems in shaping economic dynamics. The findings contribute to the literature by offering insights into the nuanced relationship between exchange rate policies and stock markets, with implications for policymakers, investors, and financial analysts. By focusing on Kuwait and Saudi Arabia, two pivotal economies, the study addresses a gap in the literature, providing a comparative perspective. Policymakers can use the findings to understand the potential impact of exchange rate policies on economic indicators. Investors can leverage the conclusions to inform their decision-making, considering the nuances of exchange rate dynamics. The study finds that both countries peg their currencies to major world currencies, primarily the USD, and identifies a strong correlation between the Kuwait Stock Index and the Saudi Tasi Index.

Assessing Regional Weather's Impact on Spinal Cord Injury Survivors, Caregivers, and General Public in Miami, Florida.

(1) Background: Climate change is increasing the already frequent diverse extreme weather events (EWE) across geographic locations, directly and indirectly impacting human health. However, current ongoing research fails to address the magnitude of these indirect impacts, including healthcare access. Vulnerable populations such as persons with spinal cord injury (pSCI) face added physiologic burden such as thermoregulation or mobility challenges like closure of public transportation. Our exploratory research assessed commute and transport to healthcare facilities as well as the knowledge, attitudes and behaviors (KAB) of pSCI regarding EWE and climate change when compared to pSCI caregivers (CG) and the general public (GP). (2) Methods: A KAB survey was employed to conduct a cross-sectional assessment of pSCI, CG, and GP in Miami from October through November 2019 using snowball sampling. Descriptive and logistic regression statistical analyses were used. (3) Results: Of 65 eligible survey respondents, 27 (41.5%) were pSCI, 11 (17%) CG, and 27 (41.5%) GP. Overall, pSCI reported EWE, particularly flooding and heavy rain, affecting their daily activities including healthcare appointments, more frequently than CG or GP. The overall models for logistic regression looking at commute to and attendance of healthcare appointments were statistically significant. pSCI self-report being less vulnerable than others, and a large proportion of each group was not fully convinced climate change is happening. (4) Conclusions: This study provided insight to the KAB of 3 population subgroups in Miami, Florida. pSCI are significantly more vulnerable to the effects of regional weather events yet exhibit disproportionate self-perception of their vulnerability. Continued and more comprehensive research is needed to characterize the barriers that vulnerable populations face during weather events.

Clinical features and risk factors of primary Sjögren's syndrome complicated with severe pneumonia: a case-control study.

To analyze clinical characteristics, risk factors, pathogen distribution, and prognostic markers in primary Sjögren's syndrome (pSS) patients with severe pneumonia (SP) compared to those without severe pneumonia (NSP). This case-control study included 24 hospitalized pSS patients with SP and 96 NSP at the first affiliated hospital of Soochow university from June 2014 to May 2023. Data encompassing demographics, comorbidities, treatments, and laboratory results were retrospectively collected. Univariate and multivariate regression analyses, ROC curves, and statistical analyses using SPSS 23.0 assessed risk factors. The study retrospectively analyzed clinical features and risk factors, highlighting distinct parameters between pSS patients with and without SP. Marked differences were observed in several parameters: pSS activity(P < 0.001), white blood cell (P = 0.043), lymphocyte (P < 0.001), neutrophils (P = 0.042), C-reactive protein (P = 0.042), and CD8+ T cell (P = 0.017). Notably, lymphocyte count and SS activity demonstrated robust discrimination ability (AUC > 0.85). C-reactive protein (CRP), procalcitonin, CD4+ T cell, and IgA showed significant associations with SP; higher CRP levels correlated with increased risk, while lower CD4+ T cell and IgA levels associated with increased risk. SS activity significantly impacted outcomes. Various biomarkers exhibited diverse discriminatory abilities but lacked strong predictive associations with outcomes. pSS patients with SP exhibited higher disease activity and altered immune profiles compared to those NSP. Lymphocyte count and SS activity emerged as robust discriminators. Higher CRP levels correlated with increased risk of SP, while lower CD4+T cell and IgA levels associated with increased risk. SS activity significantly impacted patient outcomes. Key Points • pSS patients with SP exhibited higher disease activity and altered immune profiles compared to those NSP. • Lymphocyte count and SS activity emerged as robust discriminators. • Higher CRP levels correlated with increased risk of SP, while lower CD4+ T cell and IgA levels associated with decreased risk. • SS activity significantly impacted patient outcomes.

The Effect of Profitability, Liquidity, Institutional Ownership, and Managerial Ownership on Capital Structure

This study aims to obtain empirical evidence on the effect of profitability as measured by Return on Assets (ROA), liquidity measured by Current Ratio (CR), institutional ownership, and managerial ownership on capital structure. The population of this study is companies listed as consumers of the non-cyclical sector on the IDX in 2018-2022, as many as 113 issuers. The method used is a quantitative method with statistical analysis of panel data regression. Capital structure is the dependent variable, and profitability, liquidity, institutional ownership, and managerial ownership are independent variables. The method used is a quantitative method with statistical analysis of panel data regression with the SPSS Analysis tool. Capital structure is a framework that describes how equity and debt are used to finance company operations to generate optimal returns for shareholders and maximize company returns by considering the level of risk. The results showed that partially the Probability (ROA) and Liquidity (CR) were significant to the Capital Structure (DER). Institutional and managerial ownership have no significant effect on the Capital Structure (DER).

Patterns of water use by the Australian native Melaleuca styphelioides in urban environments and comparison of transpiration prediction by three different micrometeorological models

Key messageThe high-quality sap flow dataset of Melaleuca styphelioides could assists local councils in assessing tree water use and aids in the development of an urban tree sustainable planting management planTrees have a vital part to play in urban ecosystems, offering ecological, economic, and social advantages in addition to beautifying our suburbs. Knowledge of tree water use in urban environments is crucial for facilitating urban greening when there is a perception that growing trees on the street verge on expansive soils poses a risk to pavement and buildings. Information on long-term water use by individual trees in an urban environment is essential for local councils in developing urban tree management plans for sustainable planning of trees; however, this information is scarce. Micrometeorological models have commonly been used to estimate the canopy transpiration of plants in the absence of sap flow data. However, the reliability and accuracy of these models have rarely been assessed using sap flow measurements at the field site. This study aimed to provide the water use data of four individual Australian native Melaleuca styphelioides Sm. using sap flow instruments over 25 months. Tree transpiration, estimated based on three commonly used micrometeorological models using weather parameters and tree characteristics, was assessed and compared with sap flow measurements by employing the linear regression statistical analysis. The results revealed that the modified Penman–Monteith (PM) model demonstrated the highest level of accuracy among the evaluated models, consistently yielding lower errors and providing more reliable estimates of tree water use. This suggests that this model may be more appropriate for predicting plant water use in situations where sap flow data are unavailable.

청년 아르바이트생의 차별경험과 진로미결정의 관계

Objectives In this study, we tested the mediating effect of belief in a just world in the relationship between young part-time workers' experiences of discrimination and career indecision.&#x0D; Methods An online survey was conducted targeting young people aged 15 to 34 with part-time work experience. The final 259 copies were used for statistical analysis. Descriptive statistical analysis, reliability analysis, correlation analysis, and regression analysis were performed using the SPSS 23.0 statistical program. And to verify the mediation effect, bootstrapping was performed to verify statistical significance.&#x0D; Results The average experience of discrimination was 3.06, the average career indecision was 2.32, and the average belief in a fair world was 3.77. and the average belief in a just world was 3.77. There was a positive correlation that the more discrimination experiences young part-time workers had, the higher their career indecision. There was a negative correlation between the experience of discrimination and overall belief in a just world, distributive justice belief, and procedural justice belief. It was confirmed that belief in a just world had a full mediating effect on the impact of youth discrimination experiences on career indecision. In addition, the partial mediating effect of distributive justice belief and the full mediating effect of procedural justice belief, which are subvariables of belief in a just world, were confirmed.&#x0D; Conclusions This study emphasizes the need to consider the cognitive variable of belief in a just world in the relationship between young part-time workers' experiences of discrimination and career indecision. Based on this, we laid the foundation to reduce the career indecision of young part-time workers who are experiencing discrimination and provide education and counseling opportunities to help young people enter the labor market.&#x0D;
