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

Abstract

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.
Automated Urine Screening and Residual Antimicrobial Activity Test for Rapid Diagnosis of Urinary Tract Infections in Ambulatory Patients: A Laboratory Evaluation of HB&L Uroquattro Instrument
Authors: Snegarova-Toneva V. , Niyazi D. , Stoeva T. 
Published: October 2024

Abstract

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.
Models of Ethical Decision Making in the Field of Healthcare Services – A Literature Review
Authors: Georgieva V. , Andreevska K. , Petkova V. 
Published: October 2024

Abstract
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

Abstract
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

Abstract

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

Abstract

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.

Abstract
With the continuous development and integration of information technology and industrialization-related technologies, industrial Internet control system security attacks occur frequently, and it is more and more important to build an information security protection system. This study focuses on the research improvement from two aspects of access control and intrusion prevention and designs an industrial Internet security access control strategy based on the homomorphic encryption algorithm of the Hyper Elliptic Curve Cryptosystem (HCC) and the key splitting algorithm based on threshold. Meanwhile, the convolutional neural network, two-way gating loop unit, and multi-head attention mechanism are integrated to construct the CMAG intrusion detection model. The encryption algorithm and CMAG model are applied and analyzed. The encryption and decryption times of this paper’s algorithm are both relatively smooth, with an average time consumption of about 1.93ms and 0.46ms, respectively, and significantly better than other algorithms with the increase in the number of bits. The throughput of this paper’s encryption algorithm is 13.68 KB/s, which is approximately 2 times, 19 times, and 29 times higher than the throughput of GM, ElGamal, and Paillier algorithms, respectively. The other algorithms cannot match its throughput rate during decryption. The CMAG model has an accuracy of 99.14%, which is better than that of the other models, and its average checking accuracy, average recall, and average F1-Score are 0.9889, 0.9783, and 0.9834, respectively, which are 1.25%-5.16%, 4.31%-7.19%, and 3.32%, respectively, compared with that of the other three algorithms. 7.19% and 3.32%-6.76%, respectively. This paper is of great practical significance for the construction and optimization of a big data information security protection system in an industrial Internet environment.
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

Abstract
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.
