RESUMEN

BACKGROUND: The use of complementary therapies in the general population is increasing, so it is necessary to understand the training that health professionals receive in this type of therapy in their training plans, as they are often the primary source of information for patients. Our aim was to investigate Spanish universities that offer subjects on complementary therapies in their nursing degree programs. METHODS: This study is an observational, descriptive, cross-sectional study. For this purpose, we used a document published on the website of the Ministry of Universities as the working document. Additionally, a literature search was conducted up to September 2023 in the PubMed database, along with reverse searches. RESULTS: Out of a total of 62 universities, only 16 (29%) offer a subject related to this type of therapy, 27.5% (11) are public universities and 22.7% (5) are private universities, most of them being optional subjects. CONCLUSIONS: The training content on complementary care in nursing degree programs in Spanish universities is scarce, highlighting the potential benefit of expanding and promoting it, in line with the recommendations of the World Health Organization.

RESUMEN

Background: Numerous studies in the literature have aimed to evaluate the difficulty level of removing third molars. However, most of these studies have focused on the lower third molars, which can lead to complications. There is a lack of a method to determine the complexity of upper third molar extraction. Therefore, this study's objective was to develop an equation using multiple linear regression to estimate the extraction time of an upper third molar based on its complexity. Methods: This study involved patients enrolled in the Master of Oral Surgery program at the University of Seville. To determine their relationship with surgical time, the researchers analyzed various factors, such as depth, root morphology, and the need for odontosection. They then validated their findings by studying patients treated at Palmaplanas Hospital in Mallorca. Results: The cohort analysis from the University of Seville revealed significant associations between surgical time and the identified factors. A regression equation design was performed to predict the total duration of surgical intervention for wisdom teeth extraction. This equation incorporates several independent variables, represented by Xi, together with a constant term, C, and the corresponding coefficients, Bi, which weight the impact of each variable on the intervention time. The results are as follows: -0.312 (spatial relationship), 0.651 (depth), -0.443 (bone and mucosa integrity), 0.214 (roots), -0.745 (ostectomy), 0.713 (odontosection), and -0.426 (suture). Upon application of the statistical methodology to the Palmaplanas Hospital cohort, a regression coefficient of 0.770 was determined. This indicates a strong correlation between the input data and the estimated surgical time. Conclusions: In conclusion, the proposed formula demonstrates notable validity in predicting the surgical time required to extract upper third molars.

RESUMEN

A 38-year-old man presented with an erythematous papule over a longstanding back tattoo. Dermoscopic examination revealed a polymorphous vascular pattern with serpentine and dotted vessels, and shiny white-blueish lines indicating a fibrous stroma mixed with tattoo pigment. Histopathological analysis confirmed fibroepithelioma of Pinkus (FeP). FeP typically presents as an erythematous or hypopigmented tumor and may mimic benign and malignant lesions. This case highlights the unique presentation of FeP over a tattoo, underscoring the importance of dermoscopy in differential diagnosis. Surgical excision remains the treatment of choice. This is the first documented case of FeP arising over a tattoo.

RESUMEN

Whole genome sequencing (WGS) has become a vital tool in clinical microbiology, playing an important role in outbreak investigations, molecular surveillance, and identification of bacterial species, resistance mechanisms and virulence factors. However, the complexity of WGS data presents challenges in interpretation and reporting, requiring tailored strategies to enhance efficiency and impact. This study explores the diverse needs of key stakeholders in healthcare, including clinical management, laboratory work, public surveillance and epidemiology, infection prevention and control, and academic research, regarding WGS-based reporting of clinically relevant bacterial species. In order to determine preferences regarding WGS reports, human-centered design approach was employed, involving an online survey and a subsequent workshop with stakeholders. The survey gathered responses from 64 participants representing the above mentioned healthcare sectors across geographical regions. Key findings include the identification of barriers related to data accessibility, integration with patient records, and the complexity of interpreting WGS results. As the participants designed their ideal report using nine pre-defined sections of a typical WGS report, differences in needs regarding report structure and content across stakeholders became evident. The workshop discussions further highlighted the need to feature critical findings and quality metrics prominently in reports, as well as the demand for flexible report designs. Commonalities were observed across stakeholder-specific reporting templates, such as the uniform ranking of certain report sections, but preferences regarding the depth of content within these sections varied. Using these findings, we suggest stakeholder-specific structures which should be considered when designing customized reporting templates. In conclusion, this study underscores the importance of tailoring WGS-based reports of clinically relevant bacteria to meet the distinct needs of diverse healthcare stakeholders. The evolving landscape of digital reporting increases the opportunities with respect to WGS reporting and its utility in managing infectious diseases and public health surveillance.

RESUMEN

Objective: The objective of the study was to analyze the diagnostic process and the time until the start of treatment of patients with idiopathic pulmonary fibrosis in relation to the publication of successive clinical practice guide. Material and methods: Multicenter, observational, ambispective study, in which patients includes in the idiopathic pulmonary fibrosis registry of the Spanish Society of Pulmonologist and Thoracic Surgery were analyzed. An electronic data collection notebook was enabled on the society's website. Sociodemographic and clinical variables were collected at diagnosis and follow-up of the patients. Results: From January 2012 to december 2019, 1064 patients were included in the registry, with 929 finally analyzed. The diagnosis process varied depending on the year in which it was performed, and the radiological pattern observed in the high-resolution computed tomography. Up to 26.3% of the cases (244) were diagnosed with chest high-resolution computed tomography and clinical evaluation. Surgical biopsy was used up to 50.2% of cases diagnosed before 2011, while it has been used in 14.2% since 2018. The median time from the onset of symptoms to diagnosis was 360 days (IQR 120-720), taking more than 2 years in the 21.0% of patients. A percentage of 79.4 of patients received antifibrotic treatment. The average time from diagnosis to the antifibrotic treatment has been 309 ± 596.5 days, with a median of 49 (IQR 0-307). Conclusions: The diagnostic process, including the time until diagnosis and the type of test used, has changed from 2011 to 2019, probably due to advances in clinical research and the publication of diagnostic-therapeutic consensus guidelines.

RESUMEN

There is no current consensus on the parameters that determine the difficulty of mandibular third molar extraction in terms of the time required, which is essential to prevent complications and optimize the time of the intervention. This study aims to obtain, using the mathematical method of multiple linear regression, an equation that allows estimating the extraction time of a lower third molar according to its complexity, as well as to validate this equation in a sample of external wisdom teeth. METHODS: A prospective cohort study on a sample of patients of the Master of Oral Surgery of the University of Seville in which multiple linear regression coefficients were calculated with a subsequent validation study of the results in the sample of patients operated in the Hospital Palmaplanas of Mallorca. RESULTS: The regression line obtained after applying the statistical methodology to the cohort of patients from the University of Seville obtained significant dependent variables such as depth, roots, and odontosection. Once applied to the cohort of patients from the Palmaplanas Hospital in Mallorca, a regression coefficient was obtained between the data received and the estimated 0.770. CONCLUSIONS: The formula proposed in this article presents significant validity in the prediction of the surgical time of extraction of the lower third molars included.

RESUMEN

BACKGROUND: Clinical simulation is effective in nursing student education, fostering autonomous learning and critical skill development in safe environments. This method is adaptable to dynamic educational approaches and integrates technology. Satisfaction and self-confidence are key elements in its evaluation. The general objective of this research was to describe the levels of satisfaction and self-confidence among undergraduate nursing students regarding the use of clinical simulation in the field of family and community nursing. METHODS: A cross-sectional descriptive study was conducted at the University of Jaén, Spain, during the 2023/2024 academic year. Data on sociodemographic aspects, satisfaction, and self-confidence were collected using a validated instrument. The statistical analysis included central measures, dispersion, and frequencies, with confidence intervals. RESULTS: The study involved 96 students in scenario 1 (family assessment) and 97 in scenario 2 (family intervention), with the majority being women. In scenario 1, the mean satisfaction score was 4.38 out of 5, and self-confidence was scored 4.44 out of 5. Prior preparation time correlated significantly with higher levels of satisfaction and self-confidence. In scenario 2, the mean scores were slightly higher but not statistically significant. CONCLUSIONS: Our study demonstrated high levels of satisfaction and self-confidence among nursing students following clinical simulations. Prior preparation was associated with better outcomes, and the quality of the simulation positively impacted the results.

RESUMEN

BACKGROUND: Older adults are vulnerable to malnutrition due to physical, psychological, and social factors. Malnutrition, a prevalent and modifiable issue in this population, is associated with an elevated risk of adverse clinical outcomes. The purpose of the study is to assess the nutritional status of older adult individuals admitted to a general hospital and examine its correlation with socio-health and demographic variables. METHODS: The study included 239 individuals aged 70 and above, employing a cross-sectional descriptive observational approach with a convenience sampling method. Sociodemographic information was gathered, and variables such as cognitive impairment, functional capacity, comorbidities, medication consumption, and nutritional status were evaluated. Statistical analysis involved descriptive calculations, bivariate analysis, and multivariate analysis, utilizing binary logistic regression. RESULTS: Approximately half of the sample were at risk of malnutrition, with a more notable prevalence among women. Factors such as age (OR = 1.04), cognitive impairment (OR = 1.06), functional dependence (OR = 0.96), and comorbidities (OR = 1.08) were linked to an elevated risk of malnutrition. In our regression model, age, cognitive impairment, and drug consumption emerged as significant predictors of malnutrition risk. CONCLUSIONS: Individuals aged 70 and above have a notably high prevalence of malnutrition risk, particularly among those experiencing functional dependence and cognitive impairment. In our sample, cognitive impairment in older adults, coupled with above-median drug consumption, emerges as the primary predictor for malnutrition risk.

RESUMEN

Fourier-transform infrared (FTIR) spectroscopy has the potential to be used for bacterial typing and outbreak characterization. We evaluated FTIR for the characterization of an outbreak caused by Elizabethkingia miricola. During the 2020-2021 period, 26 isolates (23 clinical and 3 environmental) were collected and analyzed by FTIR (IR Biotyper) and core-genome MLST (cgMLST), in addition to antimicrobial susceptibility testing. FTIR spectroscopy and cgMLST showed that 22 of the isolates were related to the outbreak, including the environmental samples, with only one discordance between both methods. Then, FTIR is useful for E. miricola typing and can be easily implemented in the laboratory.

RESUMEN

BACKGROUND: Maternal and child malnutrition represents a public health problem in Mexico Primary care (PC) is responsible for introducing women and children under five to the health system, detecting diseases on time, and providing medical services, including pharmacological treatment if necessary. Providing these services with quality is essential to improve maternal and child health. This study evaluated the quality of nutritional care during preconception, pregnancy, postpartum, infancy, and preschool age at the PC health units across six Mexican states between 2020 and 2021. METHODS: We conducted a cross-sectional study with a mixed approach in units of the Secretary of Health to assess the quality of nutritional care during preconception, pregnancy, postpartum, childhood, and preschool age. The level of quality was calculated by the percentage of compliance with 16 indicators that integrated a Quality Index of Maternal and Child Nutritional Care (ICANMI, by its Spanish acronym). Compliance by indicator, by life stage, and overall was categorized using the following cut-off points: poor quality (≤ 70%), insufficient quality (71-89%), and good quality (≥ 90%). The perceptions of the barriers and facilitators that affect maternal and child nutrition were evaluated through semi-structured interviews with health professionals (HP) and users. All qualitative instruments were developed with a gender and intercultural perspective. RESULTS: Considering the whole sample studied, maternal and child nutritional care quality during the five life stages evaluated was bad (compliance: ≤12%), reflected in the ICANMI, which had a compliance of 8.3%. Principal barriers identified to providing high-quality nutritional care were the lack of knowledge and training of health professionals, shortages of equipment, medicine, personnel, and materials, the disappearance of the social cash transfer program Prospera, the absence of local indigenous language translators to support communication between doctor and patient, and the persistence of machismo and other practices of control over women. CONCLUSIONS: These findings underscore the need for initiatives to improve the quality of nutritional care in PC facilities across Chihuahua, State of Mexico, Veracruz, Oaxaca, Chiapas, and Yucatan. It is necessary for government and health authorities, along with various stakeholders, to collaboratively devise, implement, and assess intercultural and gender-oriented policies and programs geared towards ensuring the health infrastructure and enhancing the training of health professionals to diagnose and treat the prevalence and occurrence of diverse forms of malnutrition in both maternal and child populations.


RESUMEN: ANTECEDENTES: La mala nutrición materno-infantil (MMI) representa un problema de salud pública en México. El primer nivel tiene la respondabilidad de introducir a mujeres y niños menores de 5 años al sistema de salud, detectar oportunamente las enfermedades y brindar servicios médicos incluido el farmacológico de ser necesario. Prestar estos servicios con calidad resulta elemental para mejorar la salud de la población materno-infantil. El objetivo de este estudio fue evaluar la calidad de la atención nutricional durante las etapas de preconcepción, embarazo, posparto, infancia y edad preescolar en centros de salud de seis estados de México entre 2020 y 2021. MéTODOS: Se realizó un estudio transversal con metodología mixta en 95 centros de salud la Secretaría de Salud de México para evaluar la calidad de la atención nutricional durante la preconcepción, el embarazo, el posparto, la infancia y la etapa preescolar. El nivel de calidad se calculó mediante el porcentaje de cumplimiento de 16 indicadores que a su vez integraron un Índice de Calidad de la Atención Nutricional Materno Infantil (ICANMI). El cumplimiento por indicador, etapa de vida y global fue categorizado utilizando los siguientes puntos de corte: mala calidad (≤ 70%), calidad insuficiente (71-89%) y buena calidad (≥ 90%). La percepción sobre las barreras y facilitadores que afectan la atención nutricional materno-infantil fueron identificadas a través de entrevistas semiestructuradas y grupos focales realizadas a profesionales de salud, usuarias y usuarios. Todos los instrumentos cualitativos fueron desarrollados con un enfoque de género e interculturalidad. RESULTADOS: La calidad de la atención nutricional materno infantil durante las cinco etapas de la vida evaluadas fue mala (cumplimiento: ≤12%), mientras que el ICANMI tuvo un cumplimiento de 8.3%. Las principales barreras identificadas para brindar una atención nutricional de alta calidad fueron la falta de conocimiento y capacitación de los profesionales de la salud, la escasez de equipos, medicamentos, personal y materiales, la desaparición del programa social de transferencias monetarias Prospera, la ausencia de una lengua indígena local, entre otros. Así como la persistencia de prácticas como el machismo y otras de control sobre las mujeres. CONCLUSIONES: Estos hallazgos subrayan la necesidad inmediata de implementar iniciativas que mejoren el estándar de atención nutricional en los centros de salud en Chihuahua, Estado de México, Veracruz, Oaxaca, Chiapas y Yucatán. Es necesario que el gobierno y las autoridades sanitarias, junto con diversas partes interesadas, diseñen, implementen y evalúen en colaboración políticas y programas orientados a mejorar la calidad de la atención nutricional, con perspectiva de género e interculturalidad. Este esfuerzo tiene como objetivo mitigar la prevalencia y aparición de diversas formas de desnutrición tanto en la población materna como infantil.

RESUMEN

AIMS: Dipeptidyl peptidase 4 (DPP4) has been proposed as a coreceptor for SARS-CoV-2 cellular entry. Considering that type 2 diabetes mellitus (T2DM) has been identified as the most important risk factor for SARS-CoV-2, and that gliptins (DPP4 inhibitors) are a prescribed diabetic treatment, this study aims to unravel the impact of DPP4 in the intersection of T2DM/COVID-19. MATERIALS AND METHODS: We analyzed 189 serum human samples, divided into six clinical groups (controls, T2DM, T2DM + gliptins, COVID-19, COVID-19 + T2DM, and COVID-19 + T2DM + gliptins), measuring DPP4 protein concentration and activity by Western blot, ELISA, and commercial activity kits. The obtained results were verified in Huh-7 cellular models. KEY FINDINGS: Both DPP4 concentration and activity were decreased in COVID-19 patients, and as in T2DM patients, compared to controls. Despite these lower levels, the ratio of DPP4 activity/concentration in COVID-19 sera was the highest (0.782 ± 0.289 µU/ng vs. 0.547 ± 0.050 µU/ng in controls, p < 0.0001), suggesting a compensating mechanism in these patients. Supernatants of Huh-7 cells incubated with COVID-19 serum showed a consistent and significantly lower DPP4 concentration and activity. Furthermore, COVID-19 + T2DM + gliptins patients showed a higher serum DPP4 concentration and activity than T2DM + gliptin subjects (p < 0.05), indicating that sera from COVID-19 convalescents interfere with gliptins. SIGNIFICANCE: Either SARS-CoV-2 or some metabolites present in the sera of COVID-19-convalescent patients interact with soluble DPP4 or even gliptins themselves since the inhibitory effect of gliptins on DPP4 activity is being prevented. The interactions between DPP4, gliptins, and SARS-CoV-2 should be further elucidated to reveal the mechanism of action for these interesting observations.

RESUMEN

OBJECTIVE: The screening for colorectal cancer (CRC) through the fecal occult blood test (FOBT) has achieved high implementation in Spain, although participation rates are still not optimal. At the same time, available data show significant differences in participation both among autonomous communities and among different sociodemographic groups, which raises various equity issues. This study aimed to conduct an exploratory analysis from a qualitative perspective on the attitudes, perceptions, and social images that the target population for colorectal cancer screenings holded regarding them, as well as the barriers and areas for improvement identified through these. METHODS: This study was designed using a qualitative research approach, through the conduct of four focus groups in May 2022, with a total of twenty-six participants (equal number of men and women) aged fifty to sixty-nine years. The participants were residents of the Community of Madrid, Catalonia, Andalusia, and the Basque Country (in both large and small cities), with varying educational levels and different previous experiences of participation in the CRC screening program. RESULTS: Different conceptualizations of prevention were identified, but none that encompassed cancer (especially colorectal cancer) as an element to be incorporated into daily practices since its occurrence is primarily associated with chance. In addition to the lack of knowledge about CRC compared to other types of cancer (such as breast or prostate cancer), various attitudinal barriers to participation in the CRC screening program were perceived. These included the rejection of being part of the older age group (targeted by the test), fear of waiting for the results, lack of reliability, or the sense of being able to postpone the moment. CONCLUSIONS: This study highlights the need for interventions aimed at promoting the attitude with which the invitation to participate is received and interpreted. It also emphasizes the importance of incorporating colon cancer into the dominant framework of concerns, raising awareness about the significance of early detection, and addressing potential sources of inequity. These interventions should address the broader conceptualization of the role of prevention observed among individuals with higher cultural capital and the greater normalization of screening programs found among women due to their previous experience with breast cancer screening.


OBJETIVO: El programa de cribado de cáncer colorrectal (CCR) mediante el test de sangre oculta en heces (SOH) ha alcanzado una implementación elevada en España, aunque la participación sigue sin encontrarse en cifras óptimas. A su vez, los datos disponibles ofrecen diferencias de participación significativas, tanto entre CC. AA. como entre distintos grupos sociodemográficos, lo que plantea diferentes problemas de equidad. Este estudio buscó realizar un análisis exploratorio, desde una perspectiva cualitativa, sobre las actitudes, percepciones e imágenes sociales que la población objeto del cribado de cáncer colorrectal tenía sobre el mismo, así como las barreras y elementos de mejora a partir de estas. METODOS: Este estudio se diseñó mediante un enfoque de investigación cualitativa a partir de la realización de cuatro grupos de discusión, durante el mes de mayo de 2022, a un total de veintiséis personas (igual número de hombres y mujeres) con edades de cincuenta a sesenta y nueve años, residentes en la Comunidad de Madrid, Cataluña, Andalucía y País Vasco (en grandes y pequeñas ciudades), con diferentes niveles formativos y distintas experiencias previas de participación en el programa de cribado de CCR. RESULTADOS: Se detectaron distintas conceptualizaciones de la prevención, pero ninguna que englobe el cáncer (y especialmente el colorrectal) como elemento a incorporar en las prácticas cotidianas, ya que su aparición se asocia fundamentalmente al azar. Sumado al desconocimiento del CCR frente a otros tipos (mama o próstata), se percibieron diferentes barreras de carácter actitudinal a la participación en un programa de cribado de CCR, como fueron el rechazo a formar parte del colectivo de más edad (diana de la prueba), el miedo a la espera por los resultados, la falta de fiabilidad o la sensación de poder postergar el momento. CONCLUSIONES: De este estudio se deriva la necesidad de realizar intervenciones destinadas a: favorecer la actitud con la que se recibe e interpreta la invitación a participar; a incorporar el cáncer de colon al marco dominante de preocupaciones; a concienciar con respecto de la importancia de la detección precoz; y a actuar frente a potenciales fuentes de inequidad, como la conceptualización más extensa del papel de la prevención detectada en las personas de mayor capital cultural, o la mayor normalización de los programas de cribado encontrada en las mujeres, por la experiencia previa del de mama.

RESUMEN

In this study, we examined the metabolic adaptations of a chemoresistant prostate cancer cell line in comparison to a sensitive cell line. We utilized prostate cancer LNCaP cells and subjected them to a stepwise increase in the antiandrogen 2-hydroxy-flutamide (FLU) concentration to generate a FLU-resistant cell line (LN-FLU). These LN-FLU cells displayed characteristics of cancer stem cells, exhibited drug resistance, and showed a significantly reduced expression of Cyclin D1, along with the overexpression of p16, pointing to a proliferation arrest. In comparing the cancer stem-like LN-FLU cells to the LNCaP cells, we observed a decrease in the expression of CTP-choline cytidylyl transferase α (CCTα), as well as a decline in choline kinase, suggesting altogether a downregulation of the phosphatidylcholine biosynthetic pathway. In addition, we found decreased levels of the protein methyl transferase PRMT2 and the upregulation of the histone deacetylase Sirtuin1 (Sirt1). Analysis of the human prostate cancer samples revealed similar results in a population with high expressions of the stem cell markers Oct4 and ABCB1A1. Our findings suggest that the adaptation of prostate cancer cells to antiandrogens could induce reprogramming into stem cells that survive in a low phosphocholine metabolism and cell cycle arrest and display drug resistance.

RESUMEN

Social support is an important determinant of a carer's mental health. In recent decades, despite many studies reporting on the relationship between social support and depressive symptoms in informal caregivers of adult and older dependents, there are no systematic reviews synthesizing the available evidence. The purpose of the present study was to perform a systematic review and meta-analysis on the relationship between social support and depressive symptoms in informal caregivers of adults and older dependent people. We searched PubMed, CINAHL (EBSCO), PsycINFO (ProQuest), and Scopus, up to 15 January 2023 for studies. We applied no date or language limits to our search. A random-effects model was used to pool effect estimates. The included studies were also independently assessed for quality. Publication bias was evaluated by funnel plots, Egger's regression test, and the Trim and Fill method. Ninety-three studies were included in the review, reporting on a total of 15,431 informal caregivers. We found a moderate negative association between perceived social support and caregiver depressive symptoms (78 studies; r = -0.35, 95% CI = -0.39, -0.31; low heterogeneity and low risk of publications bias) and a small negative association between received social support and caregiver self-reported depressive symptoms (12 studies; r = -0.14, 95% CI = -0.20, -0.07; low heterogeneity and low risk of publications bias). Our results indicate that social support is a clinically relevant construct for carer well-being and an important protective factor for depressive symptoms in informal caregivers of adult and older dependents.

RESUMEN

In Spain, inequities exist in implementing colorectal cancer (CRC) tests with the target population-adults aged 50 to 69-as part of population-based CRC screening programs. This research aims to further our understanding of the target population's awareness, attitudes, and perceptions of these test-based screening programs. A survey was carried out using an online panel representative of the target population, with a sample collected from 5313 individuals. Data collection took place in June 2022. Descriptive and bivariate analyses were carried out using contingency tables, the Chi-square test, and Cramer's V statistics. The sample was also segmented based on key variables. Finally, the results were analyzed using logistic regression. In the sample population, 62.5% had taken the fecal occult blood test (FOBT), 72.5% reported receiving the invitation letter to participate in the screening program, and 86.8% had prior knowledge of the FOBT. Noncompliance was mainly due to lack of symptoms (40%), non-receipt of invitation letters (39.7%), and forgetfulness or neglect (28.5%). On the contrary, receipt of the letter of invitation (OR 7.35, p < 0.01) and prior knowledge of FOBT (OR 6.32, p < 0.01) were the main variables that increased the probability of test uptake. Other significant variables included frequency of primary care visits (OR 1.71, p < 0.01) and being older (65-69 years old) (OR 1.52, p < 0.01) There is still a pressing need for greater awareness of both CRC risk factors and the benefits of early detection, as well as for overcoming the common misconception that detection should only be sought when symptoms are present.
