Compressive strength of resins for provisional prostheses: a literature review
Get PDFIntroduction: Fixed provisional prostheses are crucial in dental restoration, since they protect the pulp and periodontal tissue and allow occlusion to be evaluated. The most used materials for these prostheses are polymethyl methacrylate (PMMA) and bisacrylic resins, both known for their mechanical resistance and aesthetic stability. These materials are subjected to different conditions, such as artificial saliva, distilled water and dry environments, to evaluate their performance in the oral cavity during functional loading. Method: The study carried out was qualitative, descriptive and transversal, with a review of scientific articles from 2019 to 2024, and to achieve the search objective, reviews of scientific articles found in various databases such as PudMed, Scielo, Google Scholar were carried out. in order to support a doctoral thesis in Biomedical Sciences at the Italian University Institute of Rosario. Objective: To investigate the compressive strength of bisacrylic and polymethyl methacrylate resins for provisional prostheses exposed to different media through a systematic literature review. Results: The study focused on provisional prostheses with an optimal duration of 6 to 12 weeks, highlighting the importance of precision in their adaptation to avoid problems such as plaque accumulation and color changes. The use of appropriate materials is essential, with bis-acrylic resins being the most used due to their speed of production. Conclusion: Finally, proper planning and management of provisional prostheses in restorative dentistry is key to improving clinical outcomes and patient experience

At the same time, groups 6 and 7 (breech presentation) also had elevated rates due to complications. The highest contributors were groups 5, 2, 10 and 1 in a level III obstetric facility.Conclusion: The application of Robson\u27s classification system in Kazakhstan\u27s obstetric population revealed varying cesarean section rates, particularly among women with previous cesarean sections and breech presentations
Utility of POCUS in estimating blood volume in neurocritical patients with hyponatremia, in the Polyvalent Intensive Care Unit of the Viedma Clinical Hospital
Get PDFIntroduction: Hyponatremia is one of the most common hydroelectrolytic disorders in patients with neurocritical pathology. Estimating blood volume in critically ill patients with hyponatremia is a challenge, and this is where point-of-care ultrasound (POCUS) becomes relevant.Methods: An observational, analytical, prospective, and longitudinal study was conducted in an ICU with a high influx of neurocritical patients. Thirty-one neurocritical patients who developed acute hyponatremia participated. They were evaluated clinically, analytically, and underwent ultrasound measurements at the bedside of the patients. It was determined which of the variables (clinical, analytical, and ultrasound) achieved the greatest sensitivity and specificity when determining blood volume. Results: More than half developed hyponatremia during their stay in the ICU, the predominant gender was male with more than 61% and more than 77% had a diagnosis of head trauma. The ROC curve was able to show that the ultrasound variables presented a sensitivity of 93% and specificity of 94% with an area under the curve (AUC) of 0.93. And of these (ITV, GC, Echo-pulmonary, VEXUS and IVC indices) were the ones that best predict blood volume. In our survival analysis (Kaplan Meier) we found a mean survival of 37.5 days (36.4 - 38.49) in the group (Hypovolemic = CPS), compared to a mean survival of 27.7 days (25.4 - 29.9) in the group (Normo-hypervolemic = SIADH) (CI 95% P: 0.078), which expresses higher mortality in those neurocritical patients who developed acute hyponatremia (Normo-hypervolemic = CPS).Conclusions:More than half of the neurocritical patients developed hyponatremia during their stay in the ICU, the mean age of the patients was 44 for the hypovolemic group and 35 for the normo-hypervolemic group, the predominant gender was male and most had a diagnosis of head trauma. POCUS (LUS, VEXUS, FoCUS) showed higher sensitivity and specificity in predicting blood volume in neurocritical patients with acute hyponatremia. The time to resolution of hyponatremia after starting treatment was a median of 3 days in the hypovolemic group, in contrast to the normo-hypervolemic group, which required more time, and no cases of overcorrection were reported in either group. Neurocritical patients with acute hyponatremia (Hypovolemic = CPS) would have more days of survival compared to neurocritical patients with acute hyponatremia (Normo-hypervolemic = SIADH

Blockchain and machine learning (ML) technologies offer transformative potential to address these challenges by enhancing transparency, efficiency, and accountability in healthcare supply chains.Methods: A mixed-methods approach was adopted, combining structured surveys, semi-structured interviews, and secondary data analysis. Quantitative data were analysed using techniques such as descriptive statistics, predictive modelling (Random Forest), clustering (K-means), and anomaly detection (Isolation Forest). Qualitative data from stakeholder interviews were analysed using Natural Language Processing (NLP) to identify recurring themes and sentiment trends.Results: The analysis revealed significant inefficiencies and readiness disparities among stakeholders. Blockchain was identified as a critical tool for improving transparency, with readiness levels being the strongest predictor of adoption success. ML demonstrated robust capabilities in fraud detection, with 5% of transactions flagged as anomalies, and predictive modelling identified key factors influencing readiness. Clustering analysis revealed distinct groups of stakeholders, highlighting the need for tailored interventions to bridge readiness gaps. Sentiment analysis indicated 65% of stakeholders held positive views on blockchain and ML adoption.Conclusion: Blockchain and ML technologies have the potential to transform public healthcare financing by addressing inefficiencies, enhancing transparency, and optimizing resource allocation. However, disparities in stakeholder readiness necessitate targeted capacity-building and phased implementation strategies. These findings provide a roadmap for integrating blockchain and ML into public healthcare systems, fostering financial resilience and improving service delivery in rural and underserved areas

Ensuring sustainable development through comprehensive psychological support and population rehabilitation
Get PDFIntroduction: The article addresses the issue of state policy aimed at comprehensive psychological support and rehabilitation of the population in the context of sustainable development. Methods: The research was conducted based on empirical experience of effective management decisions in Ukraine over the past three years of the Russian-Ukrainian war, using a comprehensive approach involving analysis, synthesis, descriptive, empirical (survey method), and structural methods.Results: The study measured stress levels in different age categories before and after group psychological training sessions (duration – 2 months) to assess the effectiveness of group psychological support sessions for internally displaced persons using the PSM-25 Lemyr-Tessier-Fillion stress measurement methodology. The empirical study was conducted at the Resilience Centre (Ivano-Frankivsk) as a shelter for internally displaced persons during 2023-2024 and covered 120 people from various age groups of internally displaced persons. The results obtained from the PSM-25 Lemyr-Tessier-Fillion stress measurement method indicate significant effectiveness of group psychological training for all age groups. As statistics show, the high stress level of all respondents decreased by 7%, and the low level by 6%. Conclusions: Thus, 31% of respondents reported a high-stress level after completing group training sessions, the lowest figure compared to the percentage of respondents with medium and low-stress levels. The highest indicator, 37%, was observed in the adolescent age group (15-22 years), which is quite logical, as at this age, there is reduced capacity for self-regulation of emotional background
Mucinous cystoadenoma of cecal appendix, pre-surgical diagnosis and treatment: case report
Get PDFIntroduction: mucinous tumors of the appendix are a condition characterized by obstructive dilation of the cecal appendix caused by the intraluminal accumulation of mucous material. Their incidence is relatively low, accounting for approximately 0.2-0.3% of all appendectomies performed. Mucinous lesions are divided into two groups: 1. Non-neoplastic lesions (mucocele) 2. Neoplastic lesions (serrated polyps, hyperplastic polyps, low-grade mucinous appendiceal neoplasia, high-grade mucinous appendiceal neoplasia, mucinous adenocarcinoma). There is no typical clinical presentation for this pathology; however, it often presents as acute appendicitis or as a mass in the right lower quadrant. Improper management could lead to pseudomyxoma peritonei, which has a high mortality rate.Clinic case: a case of a patient diagnosed preoperatively with a large appendiceal mucocele is presented. An exploratory laparotomy, right hemicolectomy, and ileotransverse anastomosis were performed with a good postoperative recovery. The histopathological result reported a mucinous cystadenoma of the appendix.Conclusion: mucinous cystadenoma is an extremely rare pathology, and its perioperative identification is challenging due to its nonspecific clinical presentation. For this reason, tomography is recommended in the study of neoplasms of the right iliac fossa
Exploring the impact of sleep knowledge on nurses’ psychological and physiological health: a descriptive study
Get PDFIntroduction: Sleep plays a crucial role in nurses’ psychological and physiological well-being, yet heavy workloads and stress may compromise sleep quality. Understanding sleep disorders and their impact is essential for nurses\u27 well-being and patient care.Aim: To assess nurses\u27 knowledge of sleep and its influence on sleep quality, stress levels, and patient care outcomes.Methods: A cross-sectional study was conducted in three governmental hospitals: Damietta General Hospital, Cairo University Hospital, and Zagazig University Hospital. A stratified random sample of 246 nurses was selected using the G*Power program. Validated tools included the Knowledge of Sleep Disorders Scale (KSDS), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), and Hospital Anxiety and Depression Scale (HADS). Data were analyzed using descriptive statistics and Pearson’s correlation.Results: Nurses demonstrated moderate sleep knowledge (KSDS = 70.33±9.70) but poor sleep quality (PSQI = 9.8±1.11). Moderate daytime sleepiness was observed (ESS = 6.0±3.2), with moderate to severe insomnia (ISI = 21.9±1.36). Psychological distress levels were moderate (HADS anxiety = 7.2±3.2; depression = 5.8±3.1). Higher sleep knowledge correlated with better sleep outcomes.Conclusion: Despite moderate knowledge of sleep disorders, nurses experience poor sleep quality, insomnia, and psychological distress. Knowledge alone is insufficient to improve sleep outcomes; targeted interventions and workplace support systems are essential to mitigate sleep disturbances and stress among nurses, ultimately enhancing both their well-being and patient care quality
