Authors: Johnson Kaitlyn A. , Cline Martha , Bastian Richard P. , Eck Abigail , Davis Spencer , Davis Garrett J.
Published: October 2024

OBJECTIVE

To evaluate outcome in 60 dogs with cystine urolithiasis treated with surgical removal with and without castration and postoperative therapeutic diet to determine frequency of recurrence and urolith-free duration.

METHODS

Patient records were reviewed for dogs with documented cystine urolithiasis from September 2010 to December 2020. Medical records, client interviews, and referring veterinarians were contacted to document the absence of clinical signs associated with subsequent urolith formation and to evaluate risk factors for urolith reoccurrence.

RESULTS

80 patients were identified with cystine uroliths, with 60 qualifying for inclusion in the study. Seven dogs were neutered prior to surgery, and 25 dogs were neutered at the time of the first surgery. Recurrence occurred in 20 dogs; 17 of those patients were intact (85%) at the time of recurrent urinary signs. Of the 20 dogs with recurrence, 50% (10 of 20) were being treated with dietary modifications.

CONCLUSIONS

The risk of recurrence among neutered pets was 23% versus 47% for intact pets, but this difference was not statistically significant; however, neutered pets had a longer urolithiasis-free duration. There was no statistically significant difference in risk of recurrence and urolith-free duration between pets with and without therapeutic diet management, (30% vs 32.5%) respectively. Multivariant analysis showed no significant interaction between surgical intervention with therapeutic diet, with nonsignificant hazard ratios (HRs) for neuter status (HR = 0.503), diet (HR = 1.056), and their interaction (HR = 4.32 to 9).

CLINICAL RELEVANCE

Sexually intact (vs castrated) male dogs should be monitored more closely for recurrence of surgical cystine urolithiasis.

Authors: Snegarova-Toneva V. , Niyazi D. , Stoeva T.
Published: October 2024

Aim

the aim of this study is to evaluate the accuracy of the HB&L Uroquattro instrument (Alifax, Italy) and the Residual Antimicrobial Activity test (RAA) for rapid and correct diagnosis of Urinary Tract Infections (UTIs) and to compare the results with those obtained with the classical cultural method.

Materials and methods

A total of 1600 urine samples, collected prospectively from 842 ambulatory patients in Varna city, Bulgaria, were included in the study. All urine samples were tested for bacterial growth and for RAA by HB&L instrument (Alifax, Italy). Simultaneously, each sample was inoculated on Colorex TM Orientation agar and blood, CLED and MacConkey agars. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were determined.

Results

Among the tested 1600 urine samples, the HB&L instrument detected 343 (21.4%) positive and 1257 (78.6%) negative urine samples. The culture-based method identified 1248 as negative (78%) and 352 urine samples (22%) as positive. The HB&L system correctly identified 343 samples as positive (97.4%) and 1248 samples as negative (100%). The PPV of the rapid automated screening was 100%, and the NPV – 99.3%. The overall accuracy was 99.4%. The positive RAA rate in the whole collection of 1600 urine samples was 5.7% and was detected in 91 patients, all with symptoms of UTIs and recent antimicrobial therapy. In the whole studied group (n = 842), a total of 113 patients reported recent antimicrobial treatment (13.4%). The cultural method demonstrated bacterial growth in 63 patients with positive RAA test, but no pathogens were isolated in 28 patients with RAA detected in their urine samples.

Conclusions

The screening system demonstrates excellent sensitivity and specificity and, compared to the classical cultural method, has a much faster turnaround time. The RAA test proved a valuable diagnostic tool, particularly in patients with bacteriuria who are under antimicrobial treatment.

Authors: Georgieva V. , Andreevska K. , Petkova V.
Published: October 2024

We conducted a Pubmed/Medline database survey of ethical decision-making models in medical practice and health care.

Material and methods. The Pubmed/Medline database search included papers published from January 2000 to October 2023. Twenty-three articles were included in the current review.

Results. The present study shows that the number of articles concerning the approach to ethical decision-making in medical practice has increased in recent decades. There are many scientific articles related to ethical approaches to health decisions. Articles analyzing a model or framework for dealing with “new age” ethical situations and emerging ethical dilemmas are fewer. In recent decades, the so-called shared decision-making model has been followed more often, as shown by the present study.

Conclusions. The existence of such health models creates specific ethical situations in which patients and health professionals often find themselves. This outlines the need of developing a framework for dealing with ethical situations.
The gut-skin axis: Investigating gut microbiota dysbiosis in pemphigus and bullous pemphigoid
Authors: Arnaut Nicoleta , Ciurea Cristina Nicoleta , Cighir Anca
Published: October 2024

Gut microbiota dysbiosis has been linked with numerous autoimmune disorders and inflammatory skin pathologies. The present study is a narrative review aiming to examine dysregulations in the gut microbiota of patients with pemphigus and bullous pemphigoid, exploring how these alterations may contribute to diseases’ development and/or progression. Significant alterations in the composition of intestinal micro-biota were identified in patients with pemphigus and bullous pemphigoid: reduction in short-chain fatty acid-producing bacteria: Faecalibacterium prausnitzii, Lachnospiraceae and Coprococcus spp., which are known for their anti-inflammatory effects, and increased abundance of Escherichia coli, Shigella spp., Klebsiella spp., Bacteroides fragilis and Flavonifractor spp., which are recognized for their pro-inflammatory impact. The composition of gut microbiota might influence the pathogenesis of autoimmune bullous diseases. Modified levels of bacteria could become innovative biomarkers for the detection of high-risk individuals, monitoring disease progression and predicting response to treatment. Furthermore, regulating bacterial levels might have therapeutic effects in diminishing inflammation and disease advancement, potentially serving as future therapeutic strategies.

Authors: Suprapto Ratih Paramita , Kristianto Heri
Published: October 2024

Objective

Wound temperature is one of the wound biomarkers representing the wound healing progress. The diabetic wound is associated with a prolonged inflammation phase marked by an increasing wound temperature and erythematous wound. Purple sweet potato extract (PSP), an anthocyanin-rich plant, improved wound healing in both diabetic and non-diabetic wounds in animal studies. This study aims to know the effect of purple sweet potato ethanol extract on wound temperature and erythema in streptozotocin-induced diabetic rats.

Methods

Rats were divided into four groups: normal rats + gel placebo; diabetic rats + gel placebo; diabetic rats + PSP 10%; and diabetic rats + PSP 15%. Diabetes mellitus was induced by streptozotocin injection. After diabetic confirmation, the back of the rats was excised and the gel was administered daily for 14 days. The wound temperature was measured at the wound surface using infrared thermography on days 0, 3, 7, and 14. The wounds were photographed and erythema analysis was conducted using Corel Photo paint®.

Results

Diabetic wounds exhibited higher surface temperature compared with the normal wound (37.08°C ± 0.29 vs 35.13°C ± 0.46) on day 14 of examination and topical application the purple sweet potato ethanol extract gel 10% and 15% markedly decreased the wound temperature at day 7 and 14 compared with the diabetes wound (p<0.0001). Wound erythema was significantly reduced in the PSP 10% and 15% diabetic wound treatment groups on day 14 (p<0.05).

Conclusion

Purple sweet potato extract gel treatment was found to have the potential to reduce inflammation in diabetic wounds.

Authors: Rustempašić Medžida , Dervišević Muamer
Published: October 2024

Introduction

The aim of this research was to examine the existence of broncho-obstruction of the airways in patients suffering from chronic obstructive pulmonary disease, as well as changes in resistance values in this part of the bronchial tree after inhalation of salbutamol.

Methods

This study was designed as a prospective, interventional clinical trial that included a sample of 147 patients suffering from COPD. Patients were stratified into four groups of thirty patients each based on the severity of airflow limitation (based on the post-bronchodilator FEV1 value), according to the GOLD grade. The test was conducted at the University Clinical Center Sarajevo, Clinic for Lung Diseases and Tuberculosis “Podhrastovi”

Results

The results of our research showed that the average values of FEV1 compared to the predicted values of this parameter in subjects in the GOLD 4 group before the administration of salbutamol were statistically significantly lower than the average values of FEV1 in other subjects of the GOLD group. After the administration of salbutamol, a statistically significant increase in the value of FEV1 was registered in all tested groups. When the response to salbutamol was compared among the GOLD groups, it was assessed that the difference in the percentage increase in predicted FEV1 values after the administration of salbutamol among the tested groups was not statistically significant.

Conclusion

Bronchodilation with salbutamol and additional ipratropium had a significant effect on both mentioned parameters, especially in the COPD group, which speak in favor of the presence of increased peripheral resistance in all groups of patients. A statistically significant bronchodilator response was obtained in GOLD 1 and GOLD 2 groups, i.e. in groups of patients with milder forms of the disease.

An algorithmic study of periodization strategy optimization in combined anaerobic and anaerobic fitness training for improving athletes’ endurance qualities
Authors: Huang Gang
Published: October 2024

The principle of flexibility and change should be adopted in the process of physical training, and the optimization of periodization training strategy can only be reasonably carried out according to the specific training response of athletes in order to improve the overall athletic ability of athletes. This paper utilizes the sports training pyramid as a guide, scrutinizes the endurance qualities athletes should possess, and suggests an optimization process for the periodization training strategy, which integrates multiple elements of periodization training. Based on the physiological characteristic indexes of athletes’ cardiorespiratory endurance, a model of cardiorespiratory endurance with different periodization training and different frequencies was established, and the results of the model were inputted into a BP network model optimized by the artificial fish swarm algorithm, thus realizing the prediction of the athletes’ cardiorespiratory endurance. The maximum value of the athletes’ endurance predicted by the ASFA-BP model was 81.09N, which differed from the actual value of the athletes’ endurance only by 1.58%, and the difference in the average lung capacity index (ALCI) was only 1.58%. The difference in mean spirometry index fluctuated between [0.16 mL/kg and 0.29 mL/kg]. The optimal duration of the periodization training strategy based on the acquired endurance data was between 10 and 18 days, and the exercise training load should be reduced by approximately 46% to 65%. The effective prediction of athletes’ endurance quality can help optimize the periodization training strategy and improve athletes’ competitive level faster.

Phosphate Fertilization Improve Productivity and Chemical-Bromatological Composition of Leaf Blade of Unburned Pasture
Authors: Silva Luiz Carlos da , Almeida Lobo Francisco de
Published: October 2024

Objective: We evaluate the effects of phosphate fertilization on the leaf blade productivity of unburned Brachiaria brizantha, cv. Marandu, as well its chemical-bromatological composition compared to the pasture burning in the southwestern Amazon.
 
Theoretical Framework: Brazilian Amazon has one of the highest proportion of planted pastures in Brazil and the Brachiaria brizantha is the most used species. The burning is an important factor that lead to the gradual degradation of pastures. These circumstances generate pastures with low capability of providing feed for cattle farming. The improvement caused by burnings occurs only in short periods after burning. Some alternative sources with a low content of soluble P, in turn, increases biomass productivity and the nutritional value of cultivated species.
 
Method: A field experiment was carried out in a completely randomized blocks design. The treatments consisted of unburned pasture treated with 0, 25, 100 and 200 kg ha-1 of P compared to the pasture burning. After applying the treatments, the pasture was desiccated in order to homogenize the plant emergence and growth after the period without rain from July to September.
 
Results and Discussion: The dose of 100 kg ha-1 of P for unburned pasture promoted better productivity and mineral nutrient concentrations, and leaf quality for animal consumption was improved. Values of acid detergent fiber, neutral detergent fiber, lignin and crude protein indicate an adequate bromatological composition of leaf for animal consumption at 56 days of growth.
 
Research Implications: The practical and theoretical implications of this research are discussed, providing insights into how the results can be applied or influence practices in the field of pasture management without fire using. These implications could encompass on how to apply and how much of an alternative phosphate must be applied to the soil to supply phosphorus for B. brizantha instead of using fire in the pasture management.
 
Originality/Value: This study contributes to the literature by highlighting the superiority of phosphorus application from alternative source allied to N and K fertilization compared to the pasture burning practice in the Southwestern Amazon. This innovative approach can be used as a base for new researches and applied in the level of cattle farmers.

Published: October 2024

In order to determine the etiological agents and the rate of resistance to various antibiotics, 209 consecutive Gram-negative bacteria isolated from children admitted to Hacettepe University Children's Hospital with urinary tract infections were investigated over a three-month period. Of these, 46 (22%) were nosocomial isolates. The most frequently isolated organism was E.coli (n: 141) followed by Klebsiella spp. (39), Proteus spp. (19), Pseudomonas spp. (8) and Enterobacter spp. (2). In vitro susceptibilities were evaluated by microbroth dilution method, following NCCLS guidelines. Overall, 75 percent of the isolates were resistant to ampicillin, 52 percent were resistant to TMP/SMX and 25 percent to cefuroxime. Amikacin was the most active aminoglycoside; 93 percent of the isolates were susceptible to this agent, while resistance to gentamicin was 21 percent. Resistance to ceftazidime and ceftriaxone was 12 percent and 19 percent, respectively. Overall, resistance to imipenem was one percent and to ciprofloxacin three percent. These In vitro results should be taken into account before initiating empirical therapy; broad spectrum antibiotics should not be used if the isolate is susceptible to the older drugs in order to prevent the increase in resistance.
Two siblings with Bloom's syndrome exhibit different clinical features: possible effect of sex
Authors: Boduroğlu Koray , Tunçbilek Ergül
Published: October 2024

Bloom's syndrome is a rare autosomal recessive disease. All patients with Bloom's syndrome have prenatally onset growth retardation and an increased tendency to develop various types of cancer. Features other than these are not constant and may not be present in some of the patients. Reason for the phenotypic heterogeneity is not clear. Different mutations in the same locus may explain the heterogeneous phenotypes in different ethnic groups. Here we present a seven-year-old boy and his four-year-old sister, both with Bloom's syndrome, who exhibit different clinical features with respect to sun-sensitive skin lesions. The sister has severe facial sun-sensitive skin lesions whereas her brother has none. It is expected that two siblings who are supposed to have the same mutation should also have similar clinical features. Possible role of environmental effects and sex are discussed.

Published: October 2024

The purpose of this scientific research is to analyze the implementation of Article 2A paragraph (2) of Government Regulation Number 72/2016 concerning the obligation for the State of Indonesia, especially to have special shares in subsidiaries of former SOEs. The State of the Republic of Indonesia c.q the Ministry of SOEs followed up PP 72/2016 by issuing a letter to the Fertilizer SOE Holding to assign shares with privileges to PT PKT, PT PKG, PT PKC, and PT PIM. The establishment of the Fertilizer SOE Holding itself was carried out based on PP 28/1997 and PP 54/2011. The normative research method uses the law as a source of approach and research material to obtain conclusions that are carried out with the deductive method. The results of this study explain that the transfer of the same owned by the State of the Republic of Indonesia to PT PKT, PT PKG, PT PKC, and PT PIM to the Fertilizer SOE Holding was carried out before the enactment of PP 2/2016 which took effect on the date of promulgation on December 31, 2016. Based on this, PT PKT, PT PKG, PT PKC, and PT PIM have no obligation to issue Series A Dwi Warna Shares as per Article 2A paragraph (2) PP 72/2016. This obligation applies to ex-BUMN companies whose transfer of shares of the State of Indonesia to SOEs occurs after the entry into force and promulgation of PP 72/2016.

Numerical Simulation of Circulation Control for a Wing Section Using Coanda Jets
Authors: Rizzetta Donald P. , Garmann Daniel J.
Published: October 2024

Large-eddy simulations were carried out to describe the subsonic flow over a wing section, using Coanda-jet circulation control to augment lift. The section geometry consists of a modified supercritical airfoil, with a jet that is blown over a one-quarter circular cylindrical trailing-edge Coanda surface. Because the configuration does not include a slotted trailing-edge flap, the mechanical complexity and weight may be reduced. The computations correspond to an experimental investigation, which provides data for comparison. High-fidelity solutions were obtained to the unsteady three-dimensional Navier–Stokes equations at a chord-based Reynolds number of [Formula: see text] and freestream Mach number of 0.1. Several angles of attack were considered, and solutions were obtained both with and without circulation control. In the control cases, three different jet-mass flow rates were simulated at each angle of attack. A grid-resolution study was carried out to assure numerical accuracy. Comparisons are made between the respective cases and with the experimental data, and features of the flowfields are characterized. It was found that Coanda-jet control was able to augment lift in excess of factors of three with reasonable amounts of jet-mass flow.

Theorizing the Digital Object
Authors: Faulkner Philip , Runde Jochen
Published: October 2024

Prompted by perceived shortcomings of prevailing conceptualizations of digital technology in IS, we propose a theory aimed at capturing both the ontological complexity of digital objects qua objects, and how their identity and use is bound up with various social associations. We begin with what it is to be an object, the differences between material and nonmaterial objects, and various categories of nonmaterial objects including syntactic objects and bitstrings. Building on these categories we develop a conception of digital objects and a novel “bearer” theory of how material and nonmaterial objects combine. The role of computation is considered, and how the identity and system functions of digital objects flow from their social positioning in the communities in which they arise. Various implications of the theory are identified, focusing on its use as a conceptual frame through which to view digital phenomena, and its potential to inform existing perspectives with regard both to how digital technology per se and the relationship between people and digital technology should be theorized. These implications are illustrated with reference to secondary markets for software, the treatment of digital resources in the resource-based, knowledge-based, and service-dominant logic views of organizing, and recent work on sociomateriality.
Holistic Archetypes of IT Outsourcing Strategy: A Contingency Fit and Configurational Approach

The goal of this paper is to determine holistic archetypes of information technology (IT) outsourcing strategy. It does this through an overarching theoretical framework that integrates three dominant theories of interorganizational relations in the IT outsourcing literature, namely transaction cost economics, resource dependency, and social exchange theories. A contingency fit theoretical framing is married to a configurational approach to explicate the intricate relationships that spring up between a focal firm and its outsourcing vendors when they are working toward specific strategic objectives under varying contingencies. In line with this theoretical objective, we used qualitative comparative analysis (QCA), a set-theoretic configuration method that can handle the interdependent complexity among multiple elements of IT outsourcing. The technique was applied to a sample of 235 companies that have outsourced some or all of their IT functions. Findings at the project level of analysis empirically reveal two sets of configurations of strategic IT outsourcing elements, one set of configurations resulting in high economic benefit and the other set leading to high strategic benefit. Next, we compare similarities and differences among multiple, equifinal configurations and infer archetypes of IT outsourcing strategy internally congruent in terms of the strategic objectives as well as matching specific contextual contingencies. Our holistic archetypes take the form of theoretical propositions integrating the previous fragmented and inconsistent knowledge in IT outsourcing resulting from the causal ambiguity and complexity inherent in IT outsourcing projects as well as from divergent theories in the literature. Furthermore, by defining specific contingency boundaries, our archetypes provide managers with context-specific guidelines for strategic decisions regarding their relationships with outsourcing vendors, helping different sized firms to effectively succeed in IT outsourcing, contingent on the IT type being outsourced. Finally, we discuss new insights and implications of this study for complementing and extending the extant theories in IT outsourcing.
A Daily Field Investigation of Technology-Driven Spillovers from Work to Home
Authors: Benlian Alexander
Published: October 2024

Although recent theoretical developments and empirical studies indicate that technology-related stress may have negative and positive consequences for employees across life domains, the majority of previous IS research on technostress has focused on its downsides at work and has neglected to study how and why technology-related stress may spill over from work to home. Furthermore, while much of our knowledge of technology-related stress and its effects derives from cross-sectional studies examining between-person differences, there is a need for longitudinal, daily investigations that take a within-person view. Integrating the challenge–hindrance stressor framework with affective events theory and work–home spillover literature, we propose a broader conceptualization of technology-related stressors, referred to as technology-driven (TD) stressors, which comprise technology-driven challenge (TCS) and hindrance (THS) stressors, and examine how and why daily TCS and THS experienced at work affect the relationship between employees and their partners at home. In an experience sampling study of 115 employees who responded to daily surveys both at work and at home over a two-week period, we found that while THS are negatively related to partnership satisfaction via negative affect, TCS are positively related to partnership satisfaction via positive affect. We also investigated the moderating effect of work–home role integration (WHI) and perceived organizational support in work–home boundary management (POS) on the strength of the within-individual spillover processes. Our results show that WHI acts as a double-edged sword for letting TCS- and THS-triggered positive and negative affect spill over to partnership satisfaction, whereas POS serves as a facilitator of positive affect and as a buffer against negative affect. Broadly, our study shows that understanding daily TD work stressors is important because their negative and positive downstream effects often do not stop at employees’ workplace boundaries but actually penetrate and shape their everyday lives at home.
Combining Crowd and Machine Intelligence to Detect False News on Social Media

The explosive spread of false news on social media has severely affected many areas such as news ecosystems, politics, economics, and public trust, especially amid the COVID-19 infodemic. Machine intelligence has met with limited success in detecting and curbing false news. Human knowledge and intelligence hold great potential to complement machine-based methods. Yet they are largely underexplored in current false news detection research, especially in terms of how to efficiently utilize such information. We observe that the crowd contributes to the challenging task of assessing the veracity of news by posting responses or reporting. We propose combining these two types of scalable crowd judgments with machine intelligence to tackle the false news crisis. Specifically, we design a novel framework called CAND, which first extracts relevant human and machine judgments from data sources including news features and scalable crowd intelligence. The extracted information is then aggregated by an unsupervised Bayesian aggregation model. Evaluation based on Weibo and Twitter datasets demonstrates the effectiveness of crowd intelligence and the superior performance of the proposed framework in comparison with the benchmark methods. The results also generate many valuable insights, such as the complementary value of human and machine intelligence, the possibility of using human intelligence for early detection, and the robustness of our approach to intentional manipulation. This research significantly contributes to relevant literature on false news detection and crowd intelligence. In practice, our proposed framework serves as a feasible and effective approach for false news detection.
