[Coronary artery bypass grafting: evolution of coronary disease characteristics and immediate surgical outcomes over a decade]. / Cirugía coronaria: evolución de las características de la enfermedad coronaria y resultados inmediatos de la cirugía de revascularización miocárdica en una década.

INTRODUCTION: Several factors intervene in the evolution of the characteristics of Coronary artery bypass grafting (CABG), such as demographic changes, surgical technique, and perioperative care. Our objective was to analyze the evolution of the characteristics of coronary artery disease in patients treated with CABG and its immediate results. METHODS: In an analytical study, we analyzed a cohort of patients with isolated CABG from January 2006 to December 2008 and from January 2016 to December 2018 in Hospital Clínico Regional Concepción, Chile. After the ethics committee's approval, we reviewed the database and surgical protocols. We used Chi-square and U Mann Whitney tests for statistical analysis (SPSSv25®), considering significant p < 0,05. RESULTS: We analyzed 1,400 isolated CABG, 658 from the first period and 742 from the second, with a mean age of 62.0 ± 8.7 and 64.6 ± 9.3 respectively (p < 0.001). The subgroup with ventricular dysfunction in the second period showed a significant increase in diabetes mellitus, chronic obstructive pulmonary disease, acute myocardial infarction (AMI), and severe ventricular dysfunction. The second group decreased off-pump surgery and increased the use of ≥ 2 arterial grafts (p < 0.05). The Additive EuroSCORE I increased from 3.6 ± 2.5 to 4.4 ± 2.7 (p = 0.001). High-risk subgroup: 137 (20.8%) to 236 (31.8%), p < 0.001. Mortality of 13 (1.98%) and 16 (2.2%) in the first and second group respectively, p = 0.813. CONCLUSION: There was a significant increase in the estimated surgical risk; however, mortality remained unchanged. The increase in surgical risk is consistent with the increase in mean age and prevalence of comorbidities, as well as the increase in severe ventricular dysfunction in the group ofpatients with ventricular dysfunction and recent AMI in the second period.

Myomucosal island flaps for oropharyngeal reconstruction.

The oropharynx represents one of the most challenging areas to reconstruct for the head and neck surgeon. The buccinator myomucosal island flaps pedicled on the facial artery [tunnelized facial artery myomucosal island flap (t-FAMMIF)] or the buccal artery [buccal artery myomucosal island flap (BAMMIF)] are an ideal reconstructive option for moderate size defects measuring up to 8-9cm. Two fresh specimens have been used to show the step-by-step surgical technique of both island flaps. Design and flap extension, dissection plane, identification of the vascular pedicle, flap rotation and insetting are described. Reconstructive indications and the pros and cons of each one are discussed in this article. Myomucosal island flaps represent a very useful and versatile option for the functional reconstruction of the oropharynx. A detailed knowledge of the vascular anatomy of the cheek is key to obtain a large flap while minimizing the risk of complications.

Socioeconomic inequalities in the incidence of COVID-19 in Barcelona students.

Objective: This study aimed to assess socioeconomic inequalities in schools regarding the COVID-19 incidence during different epidemic waves among Barcelona students, differentiating by sex and educational stage. Study design: Cross-sectional ecological study. Methods: We included in the study all students from childhood to secondary education in Barcelona city. The unit of analysis was the schools. The study covered the epidemic waves coinciding with the 2020-21 and 2021-22 school courses. The cumulative incidence (CI) per school and wave was calculated. Bivariate and multivariate analyses using Poisson regression were conducted to estimate relative risks. The population attributable risk, by sex and educational stage, was calculated as a measure of impact. Results: In the second wave, higher CI in students was associated with greater school socioeconomic deprivation in all groups. In the younger girls, 24.5 % (5.2-41.4) of the CI was attributed to school socioeconomic vulnerability, increasing to 33.1 % (15.1-47.2) in older girls. During the sixth wave, the impact was lower in the most vulnerable schools in all strata. Conclusions: Socioeconomic factors significantly impacted the incidence of COVID-19 in schools, reflecting social inequalities in Barcelona. There was an inversion of the pattern of inequalities in the sixth wave compared to the previous ones. The results emphasize the need for urgent action and targeted resources to address health inequalities in education and understand the impact of epidemic dynamics on socioeconomic context.

Multiple and hereditary renal tumors: a review for radiologists.

80% of renal carcinomas (RC) are diagnosed incidentally by imaging. 2-4% of "sporadic" multifocality and 5-8% of hereditary syndromes are accepted, probably with underestimation. Multifocality, young age, familiar history, syndromic data, and certain histologies lead to suspicion of hereditary syndrome. Each tumor must be studied individually, with a multidisciplinary evaluation of the patient. Nephron-sparing therapeutic strategies and a radioprotective diagnostic approach are recommended. Relevant data for the radiologist in major RC hereditary syndromes are presented: von-Hippel-Lindau, Chromosome-3 translocation, BRCA-associated protein-1 mutation, RC associated with succinate dehydrogenase deficiency, PTEN, hereditary papillary RC, Papillary thyroid cancer- Papillary RC, Hereditary leiomyomatosis and RC, Birt-Hogg-Dubé, Tuberous sclerosis complex, Lynch, Xp11.2 translocation/TFE3 fusion, Sickle cell trait, DICER1 mutation, Hereditary hyperparathyroidism and jaw tumor, as well as the main syndromes of Wilms tumor predisposition. The concept of "non-hereditary" familial RC and other malignant and benign entities that can present as multiple renal lesions are discussed.

Impact of the COVID-19 Pandemic on Latino Families With Alzheimer Disease and Related Dementias: Qualitative Interviews With Family Caregivers and Primary Care Providers.

Background: Latino individuals experience disparities in the care of Alzheimer disease and related dementias (ADRD) and have disproportionately high COVID-19 infection and death outcomes. Objective: We aimed to gain an in-depth understanding of the impact of the COVID-19 pandemic among Latino families with ADRD in the United States. Methods: This was a qualitative study of 21 informal caregivers of Latino individuals with ADRD and 23 primary care providers who serve Latino patients. We recruited participants nationwide using convenience and snowball sampling methods and conducted remote interviews in English and Spanish. We organized the transcripts for qualitative review to identify codes and themes, using a pragmatic approach, a qualitative description methodology, and thematic analysis methods. Results: Qualitative analysis of transcripts revealed eight themes, including (1) the pandemic influenced mental and emotional health; (2) the pandemic impacted physical domains of health; (3) caregivers and care recipients lost access to engaging activities during the confinement; (4) the pandemic impacted Latino caregivers' working situation; (5) the pandemic impacted health care and community care systems; (6) health care and community care systems took measures to reduce the impact of the pandemic; (7) Latino families experienced barriers to remote communication during the pandemic; and (8) caregiver social support was critical for reducing social isolation and its sequalae. Conclusions: Latino families with ADRD experienced similar but also unique impacts compared to those reported in the general population. Unique impacts may result from Latino individuals' underserved status in the United States, commonly held cultural values, and their intersectionality with ADRD-related disability. Family caregiver social support was crucial during this time of adversity. These findings suggest the need for more equitable access, culturally appropriate and trustworthy content and delivery of health care and community services, as well as stronger financial and social supports for family caregivers.

Oropharyngeal reconstruction with buccinator myomucosal island flaps: Functional outcomes and quality of life. A retrospective observational study.

Background: The buccinator myomucosal island flaps are an excellent option for "like with like" oropharyngeal reconstruction in selected cases. We report a series of 15 patients and discuss the functional outcomes. Methods: From January 1, 2020 to February 31, 2023, 15 patients underwent oropharyngeal tumor resection and reconstruction with myomucosal island flaps. Buccal artery myomucosal island flap and tunnelized facial artery myomucosal island flap were used in 10 and 5 patients, respectively. In four cases, a total soft palate reconstruction was performed. Before removing the nasogastric tube, a videoendoscopy was performed in all cases to assess postoperative swallowing. Functional assessment was evaluated after a follow-up of at least 12 months. Speech intelligibility and patient speech perception were assessed using the Hirose's 10-point scoring system and the Voice Handicap Index. Dysphagia was assessed using the Dysphagia Outcome and Severity Scale and the Dysphagia Handicap Index. Finally, donor site morbidity was analyzed, and quality of life was assessed using the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30). Results: The median length of hospital stay was 10.5 days. Nasal feeding tube was removed on average in 8.6 days after surgery, and all patients were able to tolerate an oral soft diet. Intelligibility was very good in all cases. No major complications were detected, and donor site morbidity was low. Global quality of life was acceptable in all cases. Conclusions: Buccinator myomucosal island flaps represent a very interesting and versatile option for the functional reconstruction of oropharyngeal defects up to 7-8 cm. Level of Evidence: IV.

Targeted co-expression networks for the study of traits.

Weighted Gene Co-expression Network Analysis (WGCNA) is a widely used approach for the generation of gene co-expression networks. However, networks generated with this tool usually create large modules with a large set of functional annotations hard to decipher. We have developed TGCN, a new method to create Targeted Gene Co-expression Networks. This method identifies the transcripts that best predict the trait of interest based on gene expression using a refinement of the LASSO regression. Then, it builds the co-expression modules around those transcripts. Algorithm properties were characterized using the expression of 13 brain regions from the Genotype-Tissue Expression project. When comparing our method with WGCNA, TGCN networks lead to more precise modules that have more specific and yet rich biological meaning. Then, we illustrate its applicability by creating an APP-TGCN on The Religious Orders Study and Memory and Aging Project dataset, aiming to identify the molecular pathways specifically associated with APP role in Alzheimer's disease. Main biological findings were further validated in two independent cohorts. In conclusion, we provide a new framework that serves to create targeted networks that are smaller, biologically relevant and useful in high throughput hypothesis driven research. The TGCN R package is available on Github: https://github.com/aliciagp/TGCN .

Accuracy of intraocular lens power formulas in patients with average keratometry greater than 46 diopters.

OBJECTIVE: To compare the accuracy of Kane, Barrett Universal II, Haigis, and SRK-T formulas in eyes with average keratometry greater than 46 diopters (D). METHODS: A retrospective analysis was conducted on 101 eyes of 101 patients with average keratometry greater than 46 D. The absolute prediction error (EA) was obtained for each patient one month after surgery. The mean absolute prediction error (MEA), median absolute prediction error (MedEA) and the percentage of patients with absolute refractive error less than 0.25 D, 0.50 D, and 1.00 D were calculated for each formula analyzed. RESULTS: The Kane formula achieved the lowest MEA (0.53 ±â€¯0.43) and the lowest MedEA (0.41), followed by Barrett Universal II (MEA: 0.56 ±â€¯0.42, MedEA: 0.49), SRK-T (MEA: 0.59 ±â€¯0.44, MedEA: 0.54), and Haigis (MEA: 0.77 ±â€¯0.47, MedEA: 0.69), showing a significant difference in the results. It was also observed that the Kane formula was the most accurate, with the highest percentage of patients, with EA less than 0.25 D, 0.50 D, and 1.00 D (30.7%, 54.4%, and 86.1%, respectively), while the Haigis formula was the least accurate (12.9%, 33.7%, and 69.3%, respectively). CONCLUSION: In eyes with corneas having average keratometry greater than 46 D, the Kane formula proves to be a useful tool in intraocular lens (IOL) power calculation and demonstrates higher precision compared to the Barrett Universal II, SRK-T, and Haigis formulas.

Is perioperative COVID-19 really associated with worse surgical outcomes among vaccinated patients?

INTRODUCTION: During the surge of the SARS-CoV-2 pandemic, studies revealed high complication and morbidity rates following surgical procedures in COVID-19 positive patients. Anesthetic and surgical societies swiftly developed strategies to mitigate these risks, including a recommended postponement of elective surgeries for a minimum of 7 weeks post-COVID infection. Nowadays, with a predominantly vaccinated population, it has become crucial to discern the influencing factors on post-COVID morbidity and mortality and a reevaluation of the existing recommendations pertaining to elective surgery. METHODS: A single-center case-control study was conducted, including patients who underwent surgery between November 2021 and March 2022 and met the inclusion criteria. Eighty COVID-19 positive patients were matched 1:1 with 80 controls, each undergoing an identical intervention within a 2-week time frame. The primary outcome was 30-day postoperative mortality and secondary outcome postoperative complications (respiratory and thromboembolic). RESULTS: At the time of surgery, 88.8% of patients in the case group and 92.5% in the control group had received at least one vaccine dose. Mortality and morbidity did not show a significant difference when comparing the case and control groups (7.5% vs 6.2%, p = 0.755; 11.3% vs 8.9%, p = 0.541 respectively). In the COVID-positive group, mortality was significantly associated with age over 70 years, ASA score over III, RCRI over 1, emergency procedures, and absence of thromboembolic prophylaxis. CONCLUSIONS: In contrast to previously reported findings, we did not observe an increased morbi-mortality in patients with perioperative COVID-19 infection. It may not be necessary to delay elective interventions, except in cases with a high-risk.

Colorectal cancer screening program implementation: biennial adherence and participation patterns.

INTRODUCTION AND AIM: Adherence to colorectal cancer (CRC) screening is essential for the effectiveness of screening programs. Even though organized screening programs can improve the quality of the process and adherence, there are still challenges to overcome. The aim of the present study, in which we implemented a biennial organized screening program for CRC, was to describe adherence and participation patterns. MATERIALS AND METHODS: A longitudinal, descriptive study was conducted, in which a team of trained patient navigators carried out interventions, with reminders via cellphone communication, to follow a cohort of 301 subjects eligible for CRC screening, utilizing a fecal immunochemical test (FIT). All the follow-up subjects received a FIT kit. RESULTS: A total of 747 cellphone calls were made and divided into three interventions. From the initial cohort, 126 subjects completed their biennial screening process through the FIT, indicating a consistent adherence rate of 41.8% to our program. The participation patterns were: 126 consistent participants (41.8%), 160 inconsistent participants (53.2%), and 15 participants that were never contacted (5%). CONCLUSIONS: In conclusion, our study underlines the importance of organized screening programs in the early detection of CRC. The implementation of follow-up interventions, through reminders and the training of patient navigators, can improve adherence, but there is a need for examining new strategies, to overcome barriers to communication via cellphone.

[Hip fracture in elderly and COVID-19 infection. Report of 3 cases]. / Fractura de cadera en el anciano e infección por COVID-19. Descripción de 3 casos.

Since its first description in china in January 2020, COVID-19 pandemia outbreak has affected health organization and conventional care in all settings as wards, intensive care and surgery. Hip fracture patients usually are older and have a lot of comorbidities. This type of patientes benefit from early surgery. However, surgery in COVID-19 patients with active infection is associate with bad outcomes and mortality. We present three patients with COVID infection undergoing hip fracture surgery. Surgery was performed tree weeks after admission. Despite have risk factor (old age, arterial hypertension, elevated inflammatory parameters) the outcome was good and were discharged from hospital without events.

Las Leucemias y linfomas constituyen las enfermedades oncológicas más frecuentes en pediatría y las bacteriemias representan infecciones graves en estos pacientes. Objetivos: describir los microorganismos aislados de sangre en pacientes con leucemia aguda o linfoma pediátrico; comparar la incidencia de aislamientos según enfermedad de base; detallar las variaciones en la incidencia de dichos aislamientos y la evolución de su resistencia antimicrobiana. Estudio retrospectivo, observacional. Se incluyeron 823 episodios de bacteriemia en 467 pacientes pediátricos, entre julio-2016 y junio-2022, dividido en tres períodos (período-1: años 2016- 2018, período-2: años 2018-2020, período-3: años 2020-2022). Se aislaron 880 microorganismos: 55,3% gram negativos (GN), 40% gram positivos (GP) y 4,7% levaduras. En GN predominaron: enterobacterias (72%) y en GP: estreptococos del grupo viridans (SGV) (34,1%). Se encontró asociación entre LLA-enterobacterias (p=0,009) y LMA-SGV (p<0,001). Hubo aumento de GN entre los períodos 1 y 3 (p=0,02) y 2 y 3 (p=0,002) y disminución de GP entre 2 y 3 (p=0,01). Se registraron los siguientes mecanismos de resistencia: BLEE (16,4%), carbapenemasas: KPC (2,5%); MBL (2,7%) y OXA (0,2%); meticilinorresistencia en Staphylococcus aureus (20%) y estafilococos coagulasa negativos (95%), vancomicina resistencia en Enterococcus spp. (39%), SGV no sensibles a penicilina (44%) y a cefotaxima (13%). Hubo aumento de MBL entre los períodos 1 y 2 (p=0,02) y una tendencia en disminución de sensibilidad a penicilina en SGV entre el 1 y 3 (p=0,058). El conocimiento dinámico y análisis de estos datos es esencial para generar estadísticas a nivel local, fundamentales para el diseño de guías de tratamientos empíricos (AU)

Leukemias and lymphomas are the most common cancers in children and bacteremia is a severe infection in these patients. Objectives: to describe the microorganisms isolated from blood in pediatric patients with acute leukemia or lymphoma; to compare the incidence of isolates according to the underlying disease; and to detail the variations in the incidence of these isolates and the evolution of their antimicrobial resistance. Retrospective, observational study. We included 823 episodes of bacteremia in 467 pediatric patients seen between July-2016 and June-2022, divided into three periods (period-1: 2016- 2018, period-2: 2018-2020, period-3: 2020-2022). A total of 880 microorganisms were isolated: 55.3% were gram-negative (GN), 40% gram-positive (GP) and 4.7% yeasts. In GN there was a predominance of: enterobacteria (72%) and in GP viridans group streptococci (VGS) (34.1%). An association was found between ALL-enterobacteria (p=0.009) and AML-VGS (p<0.001). There was an increase in GN between periods 1 and 3 (p=0.02) and 2 and 3 (p=0.002) and a decrease in GP between 2 and 3 (p=0.01). The following resistance mechanisms were recorded: BLEE (16.4%), carbapenemases: KPC (2.5%), MBL (2.7%), and OXA (0.2%); methicillin resistance in Staphylococcus aureus (20%) and coagulase negative staphylococci (95%), vancomycin resistance in Enterococcus spp. (39%), VGS resistant to penicillin (44%) and to cefotaxime (13%). There was an increase in MBL between periods 1 and 2 (p=0.02) and a decreasing trend in penicillin sensitivity in VGS between periods 1 and 3 (p=0.058). Dynamic knowledge and analysis of these data is essential to generate statistics at the local level, which is fundamental for the design of empirical treatment guidelines (AU)

Cirugía de revascularización miocárdica: comparación de supervivencia a 10 años de la cirugía coronaria con y sin circulación extracorpórea mediante Propensity Score Matching / Ten-year survival after off-pump coronary artery bypass grafting compared with traditional bypass grafting

BACKGROUND: Long-term outcomes of Off-Pump Coronary Artery Bypass Grafting (OPCAB) as an alternative to the traditional Coronary Artery Bypass Grafting (CABG) technique with cardiopulmonary bypass (CPB) are not well defined. AIM: To compare 10-year survival of isolated OPCAB versus CABG with CPB. MATERIAL AND METHODS: Analysis of information obtained from databases, clinical records and surgical protocols of patients treated with isolated CABG between January 2006 and November 2008 at a Regional Hospital. Of 658 isolated CABG, 192 (29.2%) were OPCAB and 466 (79.9%) CPB. Propensity Score Matching (PSM) was performed to compare both groups. After PSM, two groups of 192 cases were obtained. Mortality data was obtained from the Chilean public identification service. Ten-year survival was calculated and compared with Kaplan-Meier and log-rank methods. RESULTS: Follow-up data was obtained in all cases. No statistically significant differences were found when comparing 10-year survival between OPCAB versus CPB (78.6% and 80.2% respectively, p 0.720). There was also no statistical difference in cardiovascular death free survival (90.1% with CPB versus 89.1% OPCAB, p 0.737). Survival was comparable when analyzing subgroups with diabetes mellitus, left ventricular dysfunction or chronic kidney disease, among others. CONCLUSIONS: In our series, OPBAB has a comparable 10-year survival with CABG with CPB.

Cirugía coronaria: evolución de las características de la enfermedad coronaria y resultados inmediatos de la cirugía de revascularización miocárdica en una década

Introducción: En la evolución de las características de la cirugía coronaria (CC) intervienen factores como cambios demográficos, técnica quirúrgica y cuidados perioperatorios. Nuestro objetivo es analizar la evolución de las características de la enfermedad coronaria en pacientes tratados con CC y sus resultados inmediatos. Material y Método: Estudio analítico. Cohorte de pacientes operados con CC aisladas entre enero de 2006 y diciembre de 2008, y entre enero de 2016 y diciembre de 2018 en Hospital Clínico Regional de Concepción, Chile. Revisión bases datos y protocolos quirúrgicos, previa autorización comité de ética. Se utilizó SPSSv25® y pruebas estadísticas Chi-cuadrado y U Mann-Whitney, considerando significativo p < 0,05. Resultados: Total 1.400 CC aisladas, 658 primer período y 742 segundo período. Edad promedio: 62,0 ± 8,7 y 64,6 + 9,3 años según períodos (p < 0,001). Aumentaron significativamente en el segundo período: diabetes mellitus, enfermedad pulmonar obstructiva crónica, infarto agudo al miocardio (IAM), disfunción ventricular grave dentro de subgrupo con disfunción ventricular. Disminución significativa de la cirugía sin circulación extracorpórea, y aumento significativo del uso ≥ 2 puentes arteriales en el segundo período. EuroSCORE I aditivo aumentó de 3,6 ± 2,5 a 4,4 ± 2,7 (p = 0,001). Subgrupo de alto riesgo: 137 (20,8%) a 236 (31,8%), p < 0,001. Mortalidad de 13 (1,98%) y 16 (2,2%) según períodos, p = 0,813. Discusión: Se observó aumento significativo del riesgo operatorio estimado, sin embargo, la mortalidad se mantuvo sin variación. El aumento del riesgo operatorio se condice con el aumento de la edad promedio y de la prevalencia de comorbilidades, así como del aumento de disfunción ventricular grave dentro del grupo de pacientes con disfunción ventricular e IAM reciente en el segundo período.

Infecciones asociadas al cuidado de salud en la unidad de quemados durante la pandemia SARS-CoV-2 / Healthcare-associated infections in the burn unit during the SARS-CoV-2 pandemic

Introducción: a partir de la pandemia por Covid19 se reportó variabilidad en la incidencia de las infecciones asociadas al cuidado de la salud (IACS). Con el objetivo de describir y comparar las tasas de IACS en la Unidad de Quemados de un hospital pediátrico de tercer nivel, antes y después del inicio de la pandemia se llevó a cabo este estudio. Material y métodos: estudio de cohorte, retrospectivo, descriptivo, de vigilancia epidemiológica. Se registraron todos los eventos de IACS en la Unidad de Quemados desde el 01/07/2018 hasta el 31/06/2021. Se compararon las tasas de las IACS entre el período I (PI) previo a la pandemia (07/2018-12/2019) y el período II (PII) posterior al inicio de la misma (01/2020- 06/2021). Resultados: se registraron 74 episodios de IACS, en un total de 8232 pacientes-día. Se registró una tasa global de IACS similar en ambos períodos, 10,08 ‰ pacientes-día (PI) vs 7,34 ‰ pacientes-día (PII), sin encontrarse diferencias estadísticamente significativas en las tasas de bacteriemia asociada a catéter venoso central (BSI-CVC) 3,32 ‰ días uso de CVC (PI) vs 3,20 ‰ (PII), neumonía asociada a ARM 1.43 ‰ días de uso de ARM (PI) vs un 2.02 ‰ (PII), ni infección urinaria asociada a sonda vesical (SV) 7,36 ‰ días de uso de SV (PI) vs 3,64 ‰ (PII). Conclusiones: no se observaron diferencias estadísticamente significativas en las tasas de IACS entre ambos períodos, lo cual podría justificarse con el estricto protocolo en control de infecciones implementado previo al inicio de la pandemia (AU)

Introduction: since the start of the Covid19 pandemic, variability in the incidence of healthcare-associated infections (HAIs) has been reported. This study was conducted to describe and compare the rates of HAIs in the burn unit of a tertiary pediatric hospital before and after the onset of the pandemic. Material and methods: a retrospective, descriptive, epidemiological surveillance cohort study was conducted. All HAI events in the burn unit from 01/07/2018 to 31/06/2021 were recorded. HAI rates between the pre-pandemic period I (PI) (07/2018- 12/2019) and post-pandemic period II (PII) (01/2020-06/2021) were compared. Results: 74 episodes of HAI were recorded in a total of 8232 patient-days. There was a similar overall rate of HAIs in both periods, 10.08 ‰ patient-days (PI) vs 7.34 ‰ patient-days (PII), with no statistically significant differences found in the rates of central venous catheter-related bloodstream infections (CVC-BSI) 3.32 ‰ days CVC use (PI) vs 3.20 ‰ (PII), ventilator-associated pneumonia 1. 43 ‰ days MV use (PI) vs a 2.02 ‰ (PII), or catheter-associated urinary tract infection 7.36 ‰ days catheter use (PI) vs 3.64 ‰ (PII). Conclusions: no statistically significant differences were observed in the rates of HAIs between both periods, which may be explained by the strict infection control protocol implemented prior to the onset of the pandemic (AU)

La presencia de las enfermeras en las residencias de mayores en Cantabria / The presence of nurses in Cantabria old people's home

Objetivos: Caracterizar la situación de la asistencia sociosanitaria y de dependencia en la comunidad autónoma de Cantabria y analizar la aplicación de cuidados por parte del personal de enfermería tanto del centro de salud como de los propios de los centros sociosanitarios y de dependencia. Metodología:Estudio descriptivo transversal y multicéntrico en el cual se diseñó una encuesta ad-hoc anónima enviada a todos los centros sociosanitarios de la comunidad autónoma de Cantabria para su cumplimentación. Resultados: Se obtuvieron 54 de las 60 encuestas enviadas, el total de residentes en centros sociosanitarios de Cantabria es de 5.335 personas con una media del 86,4% de pacientes dependientes y un total de 169 profesionales de enfermería que trabajan en estos centros. La ratio enfermera/paciente es de 32 pacientes por enfermera y la media de estos profesionales es de 4,12. La enfermera del centro de salud acude a los centros sociosanitarios 51,66 min/semana. Conclusiones: La situación actual es deficitaria en enfermeras por centro y en ratio por residente, cifras que no posibilitan la atención de enfermería adecuada. La ausencia de profesionales de enfermería no garantiza la continuidad de cuidados, la prevención ni el seguimiento de patologías crónicas. La presencia de enfermeras propias supone una mayor implicación, mejoras en la calidad de vida, calidad asistencial, mayor satisfacción general, minimización de errores y un descenso del intrusismo profesional (AU)

Objectives: Characterize the situation of the socio-sanitary assistance and dependency situation in the autonomous community (region) of Cantabria and to analyze the application of care by the nurses of the health center and the nurses of the sociosanitary and dependency centers. Methodology: Cross-sectional and multicenter descriptive study in which an anonymous ad-hoc survey was designed and sent to all the socio-sanitary centers of the autonomous community of Cantabria to be filled out. Results: A total of 54 of the 60 surveys sent were returned; the total number of residents in socio-sanitary centers in Cantabria is 5,335 people, with an average of 86.4% of dependent patients and a total of 169 nursing professionals who work in these centers. The nurse/patient ratio is 32 patients per nurse and the average of these professionals is 4.12. The health center nurse goes to the socio-sanitary centers 51.66 min/week. Conclusions: The current situation is deficient in nurses per center and in ratio per resident, figures that do not allow for adequate nursing care. The absence of nursing professionals does not guarantee the continuous care, prevention or monitoring of chronic pathologies.

Perinatal exposure to a high-fat diet alters proopiomelanocortin, neuropeptide Y and dopaminergic receptors gene expression and the food preference in offspring adult rats / Exposição perinatal a uma dieta hiperlipídica altera a expressão gênica de proopiomelanocortina, neuropepitídeo Y e receptores dopaminérgicos e a preferência alimentar em ratos adultos descendentes

Exposure to the hight-fat diet may alter the control of food intake promoting hyperphagia and obesity. The objective of this study was to investigate the effects of this diet on dopamine receptors (drd1 and drd2), proopiomelanocortin (pomc), neuropeptideY (npy) genes expression, and preference food in adult rats. Wistar female rats were fed a hight-fat or control diet during pregnancy and lactation. The offspring were allocated into groups: Lactation - Control (C) and High-fat (H). Post-weaning ­ Control Control (CC), offspring of mothers C, fed a control diet after weaning; Control Hight-fat (CH), offspring of mothers C, fed a hight-fat diet after weaning; Hight-fat Control (HC), offspring of mothers H, fed with control diet after weaning; and Hight-fat Hight-fat (HH), offspring of mothers H, fed a H diet after weaning. The groups CH and HH presented greater expression of drd1 in comparison to the CC. The drd2 of CH and HC presented higher gene expression than did CC. HH presented higher pomc expression in comparison to the other groups. HC also presented greater expression in comparison to CH. The npy of HH presented greater expression in relation to CH and HC. HH and HC have had a higher preference for a high-fat diet at 102º life's day. The high-fat diet altered the gene expression of the drd1, drd2, pomc and npy, and influencing the food preference for high-fat diet.

A exposição à dieta hiperlipídica pode alterar o controle da ingestão de alimentos, promovendo hiperfagia e obesidade. O objetivo deste estudo foi investigar os efeitos dessa dieta sobre a expressão gênica dos receptores de dopamina (drd1 e drd2), da proopiomelanocortina (pomc) e neuropeptídeo Y (npy), e preferência alimentar em ratos adultos. Ratas Wistar foram alimentadas com uma dieta hiperlipídica ou controle durante a gestação e lactação. Os descendentes foram alocados em grupos: Lactação ­ Controle (C) e Hiperlipídica (H). Pós-desmame - Controle Controle (CC), descendentes das genitoras do grupo controle e alimentados com dieta controle após o desmame; Controle Hiperlipídica (CH), descendentes das genitoras do grupo controle e alimentados com dieta hiperlipídica após o desmame; Hiperlipídica Controle (HC), descendentes das genitoras do grupo hiperlipídica e alimentados com dieta controle após o desmame; Hiperlipídica Hiperlipídica (HH), descendentes das genitoras do grupo hiperlipídica e alimentados com dieta hiperlipídica após o desmame. Os grupos CH e HH apresentaram maior expressão de drd1 em comparação ao CC. O drd2 de CH e HC apresentou maior expressão gênica que o CC. HH apresentou maior expressão de pomc em comparação com os outros grupos. O HC também apresentou maior expressão de pomc em comparação ao CH. O npy do HH apresentou maior expressão em relação ao CH e HC. HH e HC tiveram uma preferência maior por uma dieta rica em gordura no 102º dia de vida. A dieta hiperlipídica alterou a expressão gênica dos drd1, drd2, pomc e npy e influenciou na preferência alimentar pela dieta hiperlipídica.
