Accuracy in osteotomy drilling using a new universal and disposable drill-stop device for dental implant drills: an in vitro study using a bovine rib model.

BACKGROUND: This study aimed to evaluate the surgical accuracy of a new universal disposable stop system for implant drills (FCA Universal Drill Stop). MATERIAL AND METHODS: A total of 60 bovine ribs were included in this in vitro study. The ribs were randomized into three study groups (n=20 ribs per group). In each study group (Group1: drills without stop or control group, Group 2: prefabricated drills with stop or gold standard group, and Group 3: drills with FCA Universal Drill Stop) a total of 100 osteotomies were performed with implant drills in each group, following the drilling sequence for the placement of a dental implant of 10 mm length and 4 mm diameter. The accuracy of the depth of the osteotomies was quantified clinically (with periodontal probe) and radiologically, using ImageJ version 1.48v software. RESULTS: The order of highest to lowest accuracy (clinical and radiological) in the depth of osteotomies was: FCA Universal Drill Stop> prefabricated drills with a stop>drills without stop, with statistically significant differences being observed between both systems with stop with respect to the control group, although not between them. CONCLUSIONS: The new universal disposable stop system for implant drills, offers similar accuracy to prefabricated drills with stop, with both systems being much more accurate than implant drills without stop. Although this experimental evaluation showed favourable results, further clinical studies are necessary.

Dietary intake of Perfluorooctanesulfonic acid (PFOS) and glucose homeostasis parameters in a non-diabetic senior population.

BACKGROUND: Endocrine disruptors (EDs) have emerged as potential contributors to the development of type-2 diabetes. Perfluorooctane sulfonate (PFOS), is one of these EDs linked with chronic diseases and gathered attention due to its widespread in food. OBJECTIVE: To assess at baseline and after 1-year of follow-up associations between estimated dietary intake (DI) of PFOS, and glucose homeostasis parameters and body-mass-index (BMI) in a senior population of 4600 non-diabetic participants from the PREDIMED-plus study. METHODS: Multivariable linear regression models were conducted to assess associations between baseline PFOS-DI at lower bound (LB) and upper bound (UB) established by the EFSA, glucose homeostasis parameters and BMI. RESULTS: Compared to those in the lowest tertile, participants in the highest tertile of baseline PFOS-DI in LB and UB showed higher levels of HbA1c [ß-coefficient(CI)] [0.01 %(0.002 to 0.026), and [0.06 mg/dL(0.026 to 0.087), both p-trend ≤ 0.001], and fasting plasma glucose in the LB PFOS-DI [1.05 mg/dL(0.050 to 2.046),p-trend = 0.022]. Prospectively, a positive association between LB of PFOS-DI and BMI [0.06 kg/m2(0.014 to 0.106) per 1-SD increment of energy-adjusted PFOS-DI was shown. Participants in the top tertile showed an increase in HOMA-IR [0.06(0.016 to 0.097), p-trend = 0.005] compared to participants in the reference tertile after 1-year of follow-up. DISCUSSION: This is the first study to explore the association between DI of PFOS and glucose homeostasis. In this study, a high baseline DI of PFOS was associated with a higher levels of fasting plasma glucose and HbA1c and with an increase in HOMA-IR and BMI after 1-year of follow-up.

Effect of a nutritional intervention based on an energy-reduced Mediterranean diet on environmental impact.

OBJECTIVE: To estimate the environmental impact of a dietary intervention based on an energy-reduced Mediterranean diet (MedDiet) after one year of follow-up. METHODS: Baseline and 1-year follow-up data were used for 5800 participants aged 55-75 years with metabolic syndrome in the PREDIMED-Plus study. Food intake was estimated through a validated semiquantitative food consumption frequency questionnaire, and adherence to the MedDiet was estimated through the Diet Score. Using the EAT-Lancet Commission tables we assessed the influence of dietary intake on environmental impact (through five indicators: greenhouse gas emissions (GHG), land use, energy used, acidification and potential eutrophication). Using multivariable linear regression models, the association between the intervention and changes in each of the environmental factors was assessed. Mediation analyses were carried out to estimate to what extent changes in each of 2 components of the intervention, namely adherence to the MedDiet and caloric reduction, were responsible for the observed reductions in environmental impact. RESULTS: We observed a significant reduction in the intervention group compared to the control group in acidification levels (-13.3 vs. -9.9 g SO2-eq), eutrophication (-5.4 vs. -4.0 g PO4-eq) and land use (-2.7 vs. -1.8 m2). Adherence to the MedDiet partially mediated the association between intervention and reduction of acidification by 15 %, eutrophication by 10 % and land use by 10 %. Caloric reduction partially mediated the association with the same factors by 55 %, 51 % and 38 % respectively. In addition, adherence to the MedDiet fully mediated the association between intervention and reduction in GHG emissions by 56 % and energy use by 53 %. CONCLUSIONS: A nutritional intervention based on consumption of an energy-reduced MedDiet for one year was associated with an improvement in different environmental quality parameters.

Target sign in COVID-19, radiological interpretation and diagnostic contribution of digital thoracic tomosynthesis.

INTRODUCTION: Our objectives are: To describe the radiological semiology, clinical-analytical features and prognosis related to the target sign (TS) in COVID-19. To determine whether digital thoracic tomosynthesis (DTT) improves the diagnostic ability of radiography. MATERIAL AND METHODS: Retrospective, descriptive, single-centre, case series study, accepted by our ethical committee. Radiological, clinical, analytical and follow-up characteristics of patients with COVID-19 and TS on radiography and DTT between November 2020 and January 2021 were analysed. RESULTS: Eleven TS were collected in 7 patients, median age 35 years, 57% male. All TS presented with a central nodule and a peripheral ring, and in at least 82%, the lung in between was of normal density. All TS were located in peripheral, basal regions and 91% in posterior regions. TS were multiple in 43%. Contiguous TS shared the peripheral ring. Other findings related to pneumonia were associated in 86% of patients. DTT detected 82% more TS than radiography. Only one patient underwent a CT angiography of the pulmonary arteries, positive for acute pulmonary thromboembolism. Seventy-one per cent presented with pleuritic pain. No distinctive laboratory findings or prognostic worsening were detected. CONCLUSIONS: TS in COVID-19 predominates in peripheral and declining regions and can be multiple. Pulmonary thromboembolism was detected in one case. It occurs in young people, frequently with pleuritic pain and does not worsen the prognosis. DTT detects more than 80 % of TS than radiography.

Dermatosis perforante adquirida e Índice de Calidad de Vida en Dermatología en pacientes en hemodiálisis / Acquired perforating Dermatology Life Quality Index in dermatology in patients receiving hemodialysis

Introducción: La dermatosis perforante adquirida (DPA) es un trastorno frecuente en pacientes en hemodiálisis, y el efecto en la calidad de vida está poco descrito. Investigamos la prevalencia de DPA en pacientes en hemodiálisis, medimos y comparamos la calidad de vida asociada a DPA. Métodos: Desarrollamos un estudio prospectivo, observacional y descriptivo. Invitamos a pacientes mayores de 18 años en hemodiálisis. Se obtuvieron datos de su expediente electrónico, y se realizó exploración dermatológica. Se aplicó el Índice de Calidad de Vida en Dermatología (DLQI). Se hizo un análisis descriptivo de las variables demográficas, de las características clínicas y de los hallazgos de dermatoscopia, así como la comparación de los puntajes del DLQI. Resultados: La muestra fue de 46 pacientes, con una prevalencia de DPA del 11%. Los pacientes con DPA eran más delgados y jóvenes en comparación con los pacientes sin DPA. El tiempo en hemodiálisis fue mayor en los pacientes con DPA en comparación a los pacientes sin DPA, con una mediana de 90 versus 32 meses (p=0,015). La afección en calidad de vida fue mayor en los pacientes con DPA en comparación a los pacientes sin DPA, con un algún efecto en todos los pacientes con DPA y un 33% en los pacientes sin DPA (p=0,001). Los pacientes con DPA tuvieron con más frecuencia prurito en comparación con los pacientes sin DPA (p=0,007). Conclusiones: La edad, el tiempo en hemodiálisis y el índice de masa corporal se asocian con la presencia de DPA. Los pacientes con DPA tuvieron una prevalencia más alta de prurito y mayor afección en la calidad de vida en dermatología en comparación con los pacientes sin DPA. (AU)

Introduction: Acquired perforating dermatosis (APD) is a frequent disorder in hemodialysis patients and the effect on the quality of life is poorly described. We investigated the prevalence of APD in hemodialysis patients, measured and compared APD-associated quality of life. Methods: We developed a prospective, observational, and descriptive study. We invited patients over the age of 18 in hemodialysis. Data was obtained from their electronic file and a dermatological examination was performed. The Dermatology Life Quality Index (DLQI) was applied. Descriptive analysis of demographic variables, clinical features, and dermoscopy findings, as well as comparison of DLQI scores, was made. Results: The sample consisted of 46 patients, with a prevalence of APD of 11%. Patients with APD were leaner and younger compared to patients without APD. The time on hemodialysis was longer in patients with APD compared to those without APD, with a median of 90 versus 32 months (P=.015). The impact on quality of life was greater in patients with APD compared to those without APD, with some effect in all patients with APD and 33% in patients without APD (P=.001). Patients with APD had more frequent pruritus compared to those without APD (P=.007). Conclusions: Age, time on hemodialysis and BMI are associated with the presence of APD. Patients with APD had a higher prevalence of pruritus and a greater impact on quality of life in dermatology compared to patients without APD. (AU)

Good clinical practice recommendations for the diagnosis and treatment of gastroesophageal reflux disease. An expert review from the Asociación Mexicana de Gastroenterología.

INTRODUCTION: Gastroesophageal reflux disease (GERD) is very prevalent in the general population, with a broad spectrum of clinical manifestations, requiring accurate diagnosis and treatment. AIM: The aim of this expert review is to establish good clinical practice recommendations for the diagnosis and personalized treatment of GERD. METHODS: The good clinical practice recommendations were produced by a group of experts in GERD, members of the Asociación Mexicana de Gastroenterología (AMG), after carrying out an extensive review of the published literature and discussing each recommendation at a face-to-face meeting. This document does not aim to be a clinical practice guideline with the methodology such a document requires. RESULTS: Fifteen experts on GERD formulated 27 good clinical practice recommendations for recognizing the symptoms and complications of GERD, the rational use of diagnostic tests and medical treatment, the identification and management of refractory GERD, the overlap with functional disorders, endoscopic and surgical treatment, and GERD in the pregnant woman, older adult, and the obese patient. CONCLUSIONS: An accurate diagnosis of GERD is currently possible, enabling the prescription of a personalized treatment in patients with this condition. The goal of the good clinical practice recommendations by the group of experts from the AMG presented in this document is to aid both the general practitioner and specialist in the process of accurate diagnosis and treatment, in the patient with GERD.

Association between Beverage Consumption and Environmental Sustainability in an Adult Population with Metabolic Syndrome.

Beverages are an important part of the diet, but their environmental impact has been scarcely assessed. The aim of this study was to assess how changes in beverage consumption over a one-year period can impact the environmental sustainability of the diet. This is a one-year longitudinal study of 55-75-year-old participants with metabolic syndrome (n = 1122) within the frame of the PREDIMED-Plus study. Food and beverage intake were assessed using a validated food frequency questionnaire and a validated beverage-specific questionnaire. The Agribalyse® 3.0.1 database was used to calculate environmental impact parameters such as greenhouse gas emission, energy, water, and land use. A sustainability beverage score was created by considering the evaluated environmental markers. A higher beverage sustainability score was obtained when decreasing the consumption of bottled water, natural and packed fruit juice, milk, and drinkable dairy, soups and broths, sorbets and jellies, soft drinks, tea without sugar, beer (with and without alcohol), and wine, as well as when increasing the consumption of tap water and coffee with milk and without sugar. Beverage consumption should be considered when assessing the environmental impact of a diet. Trial registration: ISRCTN, ISRCTN89898870. Registered 5 September 2013.

Alcohol Drinking Impacts on Adiposity and Steatotic Liver Disease: Concurrent Effects on Metabolic Pathways and Cardiovascular Risks.

PURPOSE OF REVIEW: This integrative search aimed to provide a scoping overview of the relationships between the benefits and harms of alcohol drinking with cardiovascular events as associated to body fat mass and fatty liver diseases, as well as offering critical insights for precision nutrition research and personalized medicine implementation concerning cardiovascular risk management associated to ethanol consumption. RECENT FINDINGS: Frequent alcohol intake could contribute to a sustained rise in adiposity over time. Body fat distribution patterns (abdominal/gluteus-femoral) and intrahepatic accumulation of lipids have been linked to adverse cardiovascular clinical outcomes depending on ethanol intake. Therefore, there is a need to understand the complex interplay between alcohol consumption, adipose store distribution, metabolic dysfunction-associated steatotic liver disease (MASLD), and cardiovascular events in adult individuals. The current narrative review deals with underconsidered and apparently conflicting benefits concerning the amount of alcohol intake, ranging from abstention to moderation, and highlights the requirements for additional robust methodological studies and trials to interpret undertrained and existing controversies. The conclusion of this review emphasizes the need of newer multifaceted clinical approaches for precision medicine implementation, considering epidemiological strategies and pathophysiological mechanistic. Newer investigations and trials should be derived and performed particularly focusing both on alcohol's objective consequences as putatively mediated by fat deposition, including associated roles in fatty liver disease as well as to differentiate the impact of different levels of alcohol consumption (absence or moderation) concerning cardiovascular risks and accompanying clinical manifestations. Indeed, the threshold for the safe consumption of alcoholic drinks remains to be fully elucidated.

Impact of mediterranean diet promotion on environmental sustainability: a longitudinal analysis.

OBJECTIVE: This article aims to estimate the differences in environmental impact (greenhouse gas [GHG] emissions, land use, energy used, acidification and potential eutrophication) after one year of promoting a Mediterranean diet (MD). METHODS: Baseline and 1-year follow-up data from 5800 participants in the PREDIMED-Plus study were used. Each participant's food intake was estimated using validated semi-quantitative food frequency questionnaires, and the adherence to MD using the Dietary Score. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The association between MD adherence and its environmental impact was calculated using adjusted multivariate linear regression models. RESULTS: After one year of intervention, the kcal/day consumed was significantly reduced (-125,1 kcal/day), adherence to a MD pattern was improved (+0,9) and the environmental impact due to the diet was significantly reduced (GHG: -361 g/CO2-eq; Acidification:-11,5 g SO2-eq; Eutrophication:-4,7 g PO4-eq; Energy use:-842,7 kJ; and Land use:-2,2 m2). Higher adherence to MD (high vs. low) was significantly associated with lower environmental impact both at baseline and one year follow-up. Meat products had the greatest environmental impact in all the factors analysed, both at baseline and at one-year follow-up, in spite of the reduction observed in their consumption. CONCLUSIONS: A program promoting a MD, after one year of intervention, significantly reduced the environmental impact in all the factors analysed. Meat products had the greatest environmental impact in all the dimensions analysed.

Combining diaries and accelerometers to explain change in physical activity during a lifestyle intervention for adults with pre-diabetes: A PREVIEW sub-study.

Self-report and device-based measures of physical activity (PA) both have unique strengths and limitations; combining these measures should provide complementary and comprehensive insights to PA behaviours. Therefore, we aim to 1) identify PA clusters and clusters of change in PA based on self-reported daily activities and 2) assess differences in device-based PA between clusters in a lifestyle intervention, the PREVIEW diabetes prevention study. In total, 232 participants with overweight and prediabetes (147 women; 55.9 ± 9.5yrs; BMI ≥25 kg·m-2; impaired fasting glucose and/or impaired glucose tolerance) were clustered using a partitioning around medoids algorithm based on self-reported daily activities before a lifestyle intervention and their changes after 6 and 12 months. Device-assessed PA levels (PAL), sedentary time (SED), light PA (LPA), and moderate-to-vigorous PA (MVPA) were assessed using ActiSleep+ accelerometers and compared between clusters using (multivariate) analyses of covariance. At baseline, the self-reported "walking and housework" cluster had significantly higher PAL, MVPA and LPA, and less SED than the "inactive" cluster. LPA was higher only among the "cycling" cluster. There was no difference in the device-based measures between the "social-sports" and "inactive" clusters. Looking at the changes after 6 months, the "increased walking" cluster showed the greatest increase in PAL while the "increased cycling" cluster accumulated the highest amount of LPA. The "increased housework" and "increased supervised sports" reported least favourable changes in device-based PA. After 12 months, there was only minor change in activities between the "increased walking and cycling", "no change" and "increased supervised sports" clusters, with no significant differences in device-based measures. Combining self-report and device-based measures provides better insights into the behaviours that change during an intervention. Walking and cycling may be suitable activities to increase PA in adults with prediabetes.

Documento de consenso de la Sociedad Española de Neurología sobre el tratamiento de la esclerosis múltiple y manejo holístico del paciente 2023 / Consensus statement of the Spanish Society of Neurology on the treatment of multiple sclerosis and holistic patient management in 2023

El último documento de consenso del Grupo de Estudio de Enfermedades Desmielinizantes de la Sociedad Española de Neurología sobre el tratamiento de la esclerosis múltiple (EM) data del año 2016. Aunque muchas consideraciones continúan todavía vigentes, desde entonces se han producido cambios significativos en el manejo y tratamiento de esta enfermedad, motivados no solo por la aprobación de nuevos fármacos con diferentes mecanismos de acción, sino también por la evolución de conceptos otrora consolidados. Esto ha permitido abordar situaciones especiales como el embarazo y la vacunación desde otra perspectiva, e incluir nuevas variables en la toma de decisiones en práctica clínica, como plantear tratamiento modificador de la enfermedad (TME) de alta eficacia en fases tempranas, considerar la perspectiva del paciente y utilizar nuevas tecnologías como monitorización remota. Estos cambios han motivado la presente actualización del consenso mediante metodología Delphi, con el objetivo de reflejar el nuevo paradigma de manejo del paciente con EM basándose en la evidencia científica y la experiencia clínica de los participantes. Entre las principales conclusiones destacan como recomendaciones: iniciar TME inmunomodulador en el síndrome radiológico aislado con actividad radiológica persistente, evaluar la perspectiva del paciente y abandonar la terminología «líneas de tratamiento» en la clasificación de los TME (consenso mayor del 90%). Tras el diagnóstico de EM la elección del primer TME debería considerar la presencia/ausencia de factores de mal pronóstico (epidemiológicos, clínicos, radiológicos y biomarcadores) para la aparición de nuevos brotes o progresión de discapacidad, pudiendo plantear desde el inicio TME de alta eficacia.

The last consensus statement of the Spanish Society of Neurology's Demyelinating Diseases Study Group on the treatment of multiple sclerosis (MS) was issued in 2016. Although many of the positions taken remain valid, there have been significant changes in the management and treatment of MS, both due to the approval of new drugs with different action mechanisms and due to the evolution of previously fixed concepts. This has enabled new approaches to specific situations such as pregnancy and vaccination, and the inclusion of new variables in clinical decision-making, such as the early use of high-efficacy disease-modifying therapies (DMT), consideration of the patient's perspective, and the use of such novel technologies as remote monitoring. In the light of these changes, this updated consensus statement, developed according to the Delphi method, seeks to reflect the new paradigm in the management of patients with MS, based on the available scientific evidence and the clinical expertise of the participants. The most significant recommendations are that immunomodulatory DMT be started in patients with radiologically isolated syndrome with persistent radiological activity, that patient perspectives be considered, and that the term “lines of therapy” no longer be used in the classification of DMTs (> 90% consensus). Following diagnosis of MS, the first DMT should be selected according to the presence/absence of factors of poor prognosis (whether epidemiological, clinical, radiological, or biomarkers) for the occurrence of new relapses or progression of disability; high-efficacy DMTs may be considered from disease onset.

Vitamin D and risk of developing type 2 diabetes in the SUN project: a prospective cohort study.

PURPOSE: Vitamin D deficiency has been associated with multiple chronic diseases, including metabolic disorders such as insulin resistance and type 2 diabetes (T2D). The aim of the study was to analyze the association between validated predicted serum vitamin D status and the risk of developing T2D in a large prospective cohort based on a Mediterranean population. METHODS: The SUN project is a prospective and dynamic Spanish cohort that gathers university graduates who have answered lifestyle questionnaires, including a validated Food Frequency Questionnaire. The association between predicted serum vitamin D and the risk of T2D was assessed through Cox regression models according to quartiles (Q) of predicted vitamin D at baseline. The models were adjusted for potential confounders and sensitivity analyses were performed to ensure the robustness of our findings. RESULTS: Our study included a total of 18,594 participants and after a total follow-up of 238,078 person-years (median follow-up of 13.5 years), 209 individuals were diagnosed with incident T2D. We found a significant inverse association between predicted levels of serum vitamin D and the risk of developing T2D, after adjusting for potential confounders and performing different sensitivity analyses (hazard ratio Q4 vs. Q1: 0.48, 95% CI 0.26-0.88; p for trend = 0.032). CONCLUSION: The outcomes suggest that higher levels of vitamin D at baseline may be associated with a reduced risk of developing T2D.

Immune-mediated hepatitis: Basic concepts and treatment.

Immunotherapy with immune checkpoint inhibitors (ICIs) has revolutionized advanced cancer management. Nevertheless, the generalized use of these medications has led to an increase in the incidence of adverse immune-mediated events and the liver is one of the most frequently affected organs. Liver involvement associated with the administration of immunotherapy is known as immune-mediated hepatitis (IMH), whose incidence and clinical characteristics have been described by different authors. It often presents as mild elevations of amino transferase levels, seen in routine blood tests, that spontaneously return to normal, but it can also manifest as severe transaminitis, possibly leading to the permanent discontinuation of treatment. The aim of the following review was to describe the most up-to-date concepts regarding the epidemiology, diagnosis, risk factors, and progression of IMH, as well as its incidence in different types of common cancers, including hepatocellular carcinoma. Treatment recommendations according to the most current guidelines are also provided.

Acute and two-week effects of neotame, stevia rebaudioside M and sucrose-sweetened biscuits on postprandial appetite and endocrine response in adults with overweight/obesity-a randomised crossover trial from the SWEET consortium.

BACKGROUND: Sweeteners and sweetness enhancers (S&SE) are used to replace energy yielding sugars and maintain sweet taste in a wide range of products, but controversy exists about their effects on appetite and endocrine responses in reduced or no added sugar solid foods. The aim of the current study was to evaluate the acute (1 day) and repeated (two-week daily) ingestive effects of 2 S&SE vs. sucrose formulations of biscuit with fruit filling on appetite and endocrine responses in adults with overweight and obesity. METHODS: In a randomised crossover trial, 53 healthy adults (33 female, 20 male) with overweight/obesity in England and France consumed biscuits with fruit filling containing 1) sucrose, or reformulated with either 2) Stevia Rebaudioside M (StRebM) or 3) Neotame daily during three, two-week intervention periods with a two-week washout. The primary outcome was composite appetite score defined as [desire to eat + hunger + (100 - fullness) + prospective consumption]/4. FINDINGS: Each formulation elicited a similar reduction in appetite sensations (3-h postprandial net iAUC). Postprandial insulin (2-h iAUC) was lower after Neotame (95% CI (0.093, 0.166); p < 0.001; d = -0.71) and StRebM (95% CI (0.133, 0.205); p < 0.001; d = -1.01) compared to sucrose, and glucose was lower after StRebM (95% CI (0.023, 0.171); p < 0.05; d = -0.39) but not after Neotame (95% CI (-0.007, 0.145); p = 0.074; d = -0.25) compared to sucrose. There were no differences between S&SE or sucrose formulations on ghrelin, glucagon-like peptide 1 or pancreatic polypeptide iAUCs. No clinically meaningful differences between acute vs. two-weeks of daily consumption were found. INTERPRETATION: In conclusion, biscuits reformulated to replace sugar using StRebM or Neotame showed no differences in appetite or endocrine responses, acutely or after a two-week exposure, but can reduce postprandial insulin and glucose response in adults with overweight or obesity. FUNDING: The present study was funded by the Horizon 2020 program: Sweeteners and sweetness enhancers: Impact on health, obesity, safety and sustainability (acronym: SWEET, grant no: 774293).

[Choice of Family and Community Medicine in the MIR 2002-2023: An objective approach shows that it is as highly valued as hospital specialties]. / Elección de Medicina Familiar y Comunitaria en el MIR 2002-2023: un enfoque objetivo muestra que es una especialidad tan valorada como las hospitalarias.

INTRODUCTION: Currently there is a shortage of general practitioners (GP), and this is expected to increase in the coming years. Despite this need, it is a specialty that is supposedly little demanded, leaving specialized training places unfilled in recent years. The purpose of this study is to present new parameters to more objectively measure the demand and the relationship between supply and demand. METHODS: A database was used with the results of the places assigned in the MIR calls from 2002 to 2023. The calculated parameters were quoting index (CI), quote order, the order of top demand and the order of total demand of the GP specialty. The software R version 4.3.02 was used for statistical analysis. RESULTS: The specialty quotation and top demand have remained constant during the study period, while there has been a slight and progressive worsening of the total demand. Nevertheless, the total demand for Family Medicine in the last call for MIR exam was higher than that for specialties such as urology, neurology, ENT, endocrinology, oncology, intensive care medicine or neurosurgery, among others. CONCLUSIONS: In contrast to the subjective perception of the worsening attractiveness Family Medicine in the last MIR calls, using objective parameters, we found that the attractiveness of the specialty, measured as quotation (supply/demand ratio) and demand, has remained stable (with a slight worsening of total demand).

The MAPP Room Memory Test: Examining Contextual Memory Using a Novel Computerized Test in Cognitively-Unimpaired Individuals with Autosomal Dominant Alzheimer's Disease.

Contextual memory, the ability to remember spatial or temporal features related to an event, is affected in Alzheimer's disease (AD). There is a shortfall of tests that measure contextual memory. To evaluate visuospatial contextual memory, we developed a computerized cognitive test, the MAPP Room Memory Test, which requires participants to identify in which visual scene target items were previously presented. We hypothesized that cognitively-unimpaired carriers of an autosomal dominant AD mutation (Presenilin-1 E280A, n=15) would perform more poorly on this test than non-carrier family members (n=31). Compared to non-carriers, the carriers had significantly worse delayed room recognition. The results indicate that the MAPP Room Memory Test may be sensitive to subtle cognitive changes associated with risk of AD. Future studies with larger samples using the MAPP Room Memory Test and biomarkers are needed to examine whether this test may also be sensitive to the earliest pathological changes in preclinical AD.

Artroscopia de cadera como tratamiento del choque femoroacetabular con seguimiento mínimo de 10 años / Hip arthroscopy for femoroacetabular impingement with 10-year minimum follow-up

Objetivo: Valorar los resultados de la artroscopia de cadera (CAC) como tratamiento del choque femoroacetabular (CFA) con seguimiento mínimo de 10 años, y determinar las variables predictoras de reintervención quirúrgica. Material y métodos: Estudio retrospectivo de una base de datos prospectiva de pacientes intervenidos mediante CAC entre enero de 2010 y diciembre de 2011. Las lesiones del reborde acetabular se evaluaron según la clasificación ALAD. Se realizó valoración clínica y radiológica. La supervivencia de la técnica quirúrgica se calculó con la prueba de Kaplan-Meier y la prueba de regresión de Cox. Resultados: Se incluyeron en el estudio 74 pacientes con un seguimiento medio de 132 meses. La puntuación media en las escalas de valoración mejoró significativamente al final del seguimiento. Diecisiete pacientes (23,9%) fueron reintervenidos. El odds ratio de reintervención en un paciente mayor de 40 años fue de 8,08; en un paciente Tönnis 2-3 de 7,57; y en un paciente con lesión cartilaginosa ALAD 2-3 de 4,25. La supervivencia de la CAC en el CFA a 10 años fue del 77,8%, con un 45,4% en los pacientes con grado de Tönnis mayor de 1 frente al 85,2% en los pacientes con grado de Tönnis de 1 o menor (p<0,001). La variable predictora asociada a la necesidad de reintervención quirúrgica fue la degeneración articular radiológica preoperatoria (p=0,02). Conclusiones: La supervivencia de la CAC en el tratamiento del CFA a 10 años fue del 45,4% en los pacientes con grado de Tönnis mayor de 1 frente al 85,2% en los pacientes con grado de Tönnis 1 o menor. La edad, la lesión cartilaginosa y la degeneración articular incrementarían el riesgo de reintervención quirúrgica.(AU)

Purpose: To determine outcomes after hip arthroscopy (HA) for femoroacetabular impingement (FAI) at a minimun 10-year follow up and identified risk factors for revision surgery. Methods: Retrospective study of a prospective database of patients undergoing HA between January 2010 and December 2011. Rim chondral injuries were evaluated using the acetabular labral articular disruptions system (ALAD). Clinical and radiological data was obtained. Cumulative survival was estimated by Kaplan–Meier and a multivariate Cox proportional hazards model. Results: Seventy-four patients were included in the study. Mean follow-up was 132 months. There was statistically significant improvement from preoperative PROs at latest follow-up. Seventeen patients (23.9%) underwent revision surgery. Odds ratio for revision surgery was 8.08 in a patient above 40 years old, 7.57 in a patient Tönnis greater than 1, and 4.25 in a patient ALAD 2-3. Cumulative survivorship rate at 10 years was 77.8%, with a 45.4% for patients with Tönnis grade greater than 1 in front of 85.2% for patients with Tönnis grade of 1 or less (P<.001). Risk factor for revision surgery was preoperative degree of osteoarthrosis (P=.02). Conclusion: Cumulative survivorship rate at 10 years was 45.4% for patients with Tönnis grade greater than 1 in front of 85.2% for patients with Tönnis grade of 1 or less (P<.001). Age, chondral injuries, and degree of osteoarthrosis would increase the risk for revision surgery.(AU)

El odds ratio de reintervención en un paciente mayor de 40 años fue de 8,08; en un paciente Tönnis 2-3 de 7,57; y en un paciente con lesión cartilaginosa ALAD 2-3 de 4,25. La supervivencia de la CAC en el CFA a 10 años fue del 77,8%, con un 45,4% en los pacientes con grado de Tönnis mayor de 1 frente al 85,2% en los pacientes con grado de Tönnis de 1 o menor (p<0,001). La variable predictora asociada a la necesidad de reintervención quirúrgica fue la degeneración articular radiológica preoperatoria (p=0,02). Conclusiones: La supervivencia de la CAC en el tratamiento del CFA a 10 años fue del 45,4% en los pacientes con grado de Tönnis mayor de 1 frente al 85,2% en los pacientes con grado de Tönnis 1 o menor. La edad, la lesión cartilaginosa y la degeneración articular incrementarían el riesgo de reintervención quirúrgica.(AU)

Purpose: To determine outcomes after hip arthroscopy (HA) for femoroacetabular impingement (FAI) at a minimun 10-year follow up and identified risk factors for revision surgery. Methods: Retrospective study of a prospective database of patients undergoing HA between January 2010 and December 2011. Rim chondral injuries were evaluated using the acetabular labral articular disruptions system (ALAD). Clinical and radiological data was obtained. Cumulative survival was estimated by Kaplan–Meier and a multivariate Cox proportional hazards model. Results: Seventy-four patients were included in the study. Mean follow-up was 132 months. There was statistically significant improvement from preoperative PROs at latest follow-up. Seventeen patients (23.9%) underwent revision surgery. Odds ratio for revision surgery was 8.08 in a patient above 40 years old, 7.57 in a patient Tönnis greater than 1, and 4.25 in a patient ALAD 2-3. Cumulative survivorship rate at 10 years was 77.8%, with a 45.4% for patients with Tönnis grade greater than 1 in front of 85.2% for patients with Tönnis grade of 1 or less (P<.001). Risk factor for revision surgery was preoperative degree of osteoarthrosis (P=.02). Conclusion: Cumulative survivorship rate at 10 years was 45.4% for patients with Tönnis grade greater than 1 in front of 85.2% for patients with Tönnis grade of 1 or less (P<.001). Age, chondral injuries, and degree of osteoarthrosis would increase the risk for revision surgery.(AU)

Tasa de resangrado vítreo posterior a vitrectomía o facovitrectomía en pacientes con retinopatía diabética proliferativa: estudio retrospectivo / Vitreous rebleeding rate after vitrectomy or phacovitrectomy in patients with proliferative diabetic retinopathy: A retrospective study

Antecedentes: La complicación más común tras la vitrectomía en pacientes es el resangrado en cavidad vítrea. Es importante detectar los distintos factores que pueden incrementar la tasa de resangrado vítreo en estos pacientes. Objetivo: Realizar una revisión retrospectiva de la tasa de resangrado de cavidad vítrea posterior a vitrectomía o facovitrectomía. Método: Estudio retrospectivo, descriptivo y comparativo de pacientes con diagnóstico de retinopatía diabética proliferativa con procedimiento de facovitrectomía o vitrectomía. Se obtuvieron datos de antecedentes personales patológicos, tipo de intervención quirúrgica y grado del cirujano que realizó el procedimiento. Resultados: Se revisaron 1.227 expedientes de pacientes diabéticos sometidos a vitrectomía o facovitrectomía. El 65% presentaron hipertensión arterial sistémica. La tasa de filtración glomerular promedio fue del 63,50 (±32,36) ml/min/1,73m2 y la de hemoglobina glucosilada (HbA1c) del 8% (4,6 al 15%). En la comparación de variables se obtuvo una diferencia significativa de la tasa de resangrado vítreo comparando la facovitrectomía con la vitrectomía (p=0,003), y al relacionar la vitrectomía con el resangrado, se obtuvo una razón de momios de 1,44. Conclusión: Los resultados obtenidos muestran una menor tasa de resangrado en los pacientes con retinopatía diabética proliferativa sometidos a facovitrectomía.(AU)

Background: The most common complication after vitrectomy is the rebleeding in vitreous cavity. It is important to detect the different factors that can increase the vitreous rebleeding rate in these patients. Objective: To carry out a retrospective review of the rate of vitreous rebleeding after vitrectomy or phacovitrectomy. Method: Retrospective, descriptive and comparative study of patients with a diagnosis of proliferative diabetic retinopathy with phacovitrectomy or vitrectomy procedure. Personal background data, type of surgical intervention and grade of the surgeon who carried out the procedure were obtained. Results: One thousand two hundred twenty-seven files of diabetic patients with vitrectomy or phacovitrectomy were reviewed. Sixty-five percent presented systemic arterial hypertension. The average glomerular filtration rate was 63.50 (±32.36)ml/min/1.73m2 and glycosylated hemoglobin (HBA1C) of 8% (4.6-15%). In the comparison of variables, a significant difference in the rate of vitreous rebleeding was obtained comparing phacovitrectomy with vitrectomy (P=.003), in the relationship between vitrectomy with vitreous rebleeding, an odds ratio of 1.44 was obtained. Conclusion: The results obtained show a lower rate of rebleeding in patients undergoing phacovitrectomy in patients with proliferative diabetic retinopathy.(AU)
