The aim of this paper is to analyze the role of women in Asturias in October 1934, which has hardly any specific studies. Especially women from the mining working class and politicized young women actively participated in support of men; of course, almost always in functions “appropriate to their sex” (nurses, provisioners of the support of the combatants and caregivers of the children). They were victims of repression by Moors and legionnaires and some fell in combat.

Purpose: To determine trends in breast imaging services utilization among privately and government-insured patients at a national radiology practice.Method: Monthly breast imaging volume data from January 2019 to September 2022 were analyzed across five insurance types: three commercial carriers (Com1-Com3), Medicaid, and Medicare. Primary analysis involved calculating quarterly volumes and standard errors of the mean, followed by a joinpoint regression to identify trend inflection points and quarterly percentage changes (QPC). In the secondary analysis, the entire period trend was obtained and measured as the average quarterly percentage change (AQPC).Results: Between 2019 Q1 and 2022 Q3, a total of 4,640,619 breast imaging services were accessed, including 2,034,833 2D screening mammograms, 1,640,689 screening digital breast tomosynthesis, 497,592 diagnostic mammograms, 452,549 breast ultrasounds, and 14,956 breast MRIs. AQPC values for imaging modalities varied across insurance types. Medicare and Medicaid patients showed the highest rates of utilization increases, particularly for modalities other than screening breast tomosynthesis, where private insurers dominated. Variations were observed between different commercial payors.Conclusion: Breast imaging utilization increased among patients insured by Medicare and Medicaid from 2019 to 2022, outpacing that of those with private insurance. These findings contrast previous research suggesting better access and utilization among privately insured individuals, highlighting increased access for government-insured patients in this study.

Medical postgraduate trainees are given increasing levels of responsibility during training in the apprenticeship-model of training [1-3]. Responsibility is said to be a key driver of deep learning and understanding [4-7]. Trainees with greater levels of responsibility for decision making have higher levels of motivation to learn compared with trainees who self-assess as having less autonomy [5]. The Royal College of Pathologists (RCPath) indicate that ‘graded responsibility’ is part of training histopathologists and provided a framework for implementation with increasingly complex specimens suitable for reporting by more senior trainees [8,9]. 

The limits of classical equivalent computation based on time, dose, and fractionation (TDF) and linear quadratic models have been known for a long time. Medical physicists and physicians are required to provide fast and reliable interpretations regarding the delivered doses or any future prescriptions relating to treatment changes. In this letter, we propose an outline related to the different models usable for equivalent and biological doses that are likely to be the most appropriate. The used methodology is based on: the linear-quadratic-linear model of Astrahan, the repopulation effects of Dale, and the prediction of multi-fractionated treatments of Thames.

In recent years, studies on the utility of essential oils and their components in the preservation of food commodities in order to enhance shelf-life has been successfully carried out. These essential oils and their components (Carvacrol, Eugenol and Cinnamaldehyde) can be used as antimicrobials and food preservative agents; however, their use raises concerns because of several reported side effects of synthetic oils. Due to their antimicrobial potential, essential oil constituents could be used as food preservatives for grains, cereals, vegetables and fruits. The aim of the treatments was carried out on the treated cotton packaging to maximize the benefit from its antimicrobial activity to extend grain Storage periods. The cotton fabrics treated in three steps: Carboxymethylation of cotton fabric (CMC) Cationization of cotton fabric 3-Treatment of the fabrics by reactive-cyclodextrine (RCD). Modified and unmodified cotton fabrics were treated with antibacterial agent by dipping them at room temperature for 2 hours under stirring in dimethyl sulfoxide (DMSO) solution containing 200, 250, 250 ppm of Eugenol, carvacrol and cinnamaldehyde respectively the samples were then roll-squeezed at pick up 100% and dried at room temperature. All treated and untreated fabrics were subjected to antimicrobial tests. Cotton fabric composites treated with cinnamaldehyde had the highest impact on reducing microbial preparation during storage period followed by cotton fabric composite treated by Carvacrol followed by cotton fabric composite treated by Eugenol which is less impactful to reduce microbial count during the storage period.

The 2025 AHA/ACC/AANP/AAPA/ABC/ACCP/ACPM/AGS/AMA/ASPC/NMA/PCNA/SGIM guideline for the prevention, detection, evaluation, and management of arterial hypertension introduces important updates compared with the 2017 version. Given the global impact of hypertension as a major cause of cardiovascular morbidity and mortality, and the coexistence of multiple international and national recommendations, the Mexican Expert Group on Arterial Hypertension (GREHTA) conducted a structured review and comparative analysis. We contrasted the 2025 AHA/ACC recommendations with those of the European Society of Hypertension (ESH 2023), the European Society of Cardiology (ESC 2024), the Latin American Society of Hypertension (LASH 2024), and the National Medical Care Protocol of Mexico (PRONAM 2025). Our goal is to provide clinicians with a clear, evidence-based synthesis to guide practical decision-making. Key topics include definitions and thresholds, diagnostic methods, cardiovascular risk stratification, therapeutic strategies, special populations, and resistant hypertension. GREHTA emphasizes a pragmatic, regionally adapted approach, highlighting early combination therapy, risk factor integration, and systematic follow-up.

Introduction: Forensic odontology is a specialized field at the crossroads of dentistry and law, focusing on the analysis of dental evidence in legal investigations. Due to their resistance to decay and environmental degradation, teeth serve as a vital resource in age estimation and gender determination. Various techniques, including microscopic examination of the incremental lines in enamel and cementum, neonatal lines, and dentin translucency, are commonly employed for forensic analysis. To enhance the accuracy and ease of examination, there is an increasing demand for high-quality, non-demineralized tooth sections that are durable, easy to handle, and maintain uniform thickness. Aims and objectives: 1. Evaluate the effectiveness of the Rosin stain in identifying incremental lines in hard dental tissues. 2. Compare Rosin stain with Haematoxylin and Eosin stain as well as with unstained sections. Materials and methods: Sixty sound teeth were included in the study. Thin longitudinal sections of 2 mm were prepared using a diamond disc, and ground sections of 25 µm were prepared on Arkansas stone. The sections were divided into three groups: (A) sections stained with Rosin, (B) sections stained with H&E, and (C) unstained sections. The longitudinal ground sections were examined under both the Light Microscope and the Phase Contrast Microscope. The Microstructures of the teeth, such as incremental lines of enamel, dentin, and cementum, were assessed.Result  and conclusion: Rosin-stained ground sections observed under phase contrast microscopy provided better visualisation of dental microstructures than unstained or H&E-stained ground sections, suggesting Rosin enhances the identification of incremental lines in forensic dental analysis.

Background: Employee performance appraisal is essential for improving healthcare service delivery through systematic staff evaluation. In the health sector, effective appraisals support decision-making and professional development.Objective: This study aims to map and categorize existing employee performance appraisal methods in the health system using a scoping review approach.Methods: This scoping review was conducted using the JBI 2024 protocol. Articles published up to December 2024 were identified through four databases: PubMed, Scopus, Web of Science, and Google Scholar. The keywords used were “Personnel appraisal,” “Health workers,” and “Health workforce.” The inclusion criteria focused on studies assessing employee appraisal methods in health systems.Results: Of the 1,245 articles initially identified, 18 met the inclusion criteria. Appraisal methods were classified into traditional and modern categories. Traditional methods included ranking, critical incidents, and graphic rating scales. Modern approaches involved 360-degree feedback, Management by Objectives (MBO), and Behaviorally Anchored Rating Scales (BARS).Conclusion: No single appraisal method suits all healthcare environments. A hybrid approach tailored to organizational context and job roles is recommended. Emphasis should be placed on objective evaluation, customization, and the degree of scientific connection between the evaluator and the evaluated person to improve performance outcomes.

We investigate how the UV spectra of pyruvic acid (PA) and pyruvate are impacted by interactions with water molecules. In particular, we would like to understand the mechanistic origin of the blue shift in the n →− π∗ transition. Pyruvic acid is the simplest α-keto organic acid and is common in the environment. We use density functional theory to optimize geometries to determine excitation energies and find that the excitation energies of the two main pyruvic acid conformers and pyruvate blue shift when interacting with 1 to 4 water molecules, both in vacuo and in a solvent. The excitation wavelength is blue-shifted by 0.9-9.2 nm when adding water molecules to the lowest energy conformer of PA. Calculations of the UV spectra of pyruvic acid (PA) and pyruvate are crucial for understanding the impact of the interactions with water molecules.

Sagittal split osteotomy (SSO) of the mandible is still an important part of orthognathic surgery, but “bad split” fractures that happen during the surgery are still a big problem. This report describes a rare case of bilateral bad split associated with highly compact mandibular bone (D1–D2 type) in a 53-year-old male undergoing mandibular advancement. The bone was too hard for the piezoelectric and rotary tools to work, and there was very little bleeding. This caused fractures in the cortex and lingual. Postoperative computed tomography confirmed the presence of highly dense bone, correlated with delayed healing and recurrence. Consistent pre-surgical CT scanning for an assessment of the density of the mandibular bone can provide essential information about the potential risk of the osteotomy procedure in the patient. Performing a careful bone quality and density examination pre-operatively will allow the surgeons to select the most appropriate instruments and surgical techniques that will fit the patient’s individual anatomy. Such a point escalates to being very significant when dealing with the geriatric population, as bone density increase can not only alter the fracture behavior but also the recovery process during and after surgery. The inclusion of regular CT-based bone density evaluations into the preoperative routine not only facilitates the anticipation of surgical difficulties but also results in safer and more efficient osteotomies.
