Single dose of diclofenac or meloxicam for control of pain, facial swelling, and trismus in oral surgery

Background: Postoperative pain associated with removal of mandibular third molars has been documented from moderate to severe during the first 24 hours after surgery, with pain peaking between 6 and 8 hours when a conventional local anesthetic is used. Dental pain is largely inflammatory, and evidence-based medicine has shown that nonsteroidal anti-inflammatory drugs are the best analgesics for dental pain. The aim of this study was to compare the analgesic, anti-inflammatory and anti-trismus effect of a single dose of diclofenac and meloxicam after mandibular third molar extraction. Material and Methods: A total of 36 patients were randomized into two treatment groups, each with 18 patients, using a series of random numbers: Group A, was administered 100 mg of diclofenac; and Group B, 15 mg of meloxicam. Drugs were administered orally 1 hour prior to surgery. We evaluated pain intensity, analgesic consumption, swelling, as well as trismus. Results: The results of this study showed that patients receiving 15 mg of meloxicam had less postoperative pain ( P =0.04) and better aperture than those receiving 100 mg of diclofenac ( P =0.03). The meloxicam group presented less swelling than diclofenac group; however, significant statistical differences were not observed. Conclusions: Data of this double-blind, randomized, parallel-group clinical trial demonstrated that patients receiving 15 mg of preoperative meloxicam had a better postoperative analgesia and anti-trismus effect compared with who were given 100 mg of diclofenac after third molar extractions

RB mutation and RAS overexpression induce resistance to NK cell-mediated cytotoxicity in glioma cells

Several theories aim to explain the malignant transformation of cells, including the mutation of tumor suppressors and proto-oncogenes. Deletion of Rb (a tumor suppressor), overexpression of mutated Ras (a proto-oncogene), or both, are sufficient for in vitro gliomagenesis, and these genetic traits are associated with their proliferative capacity. An emerging hallmark of cancer is the ability of tumor cells to evade the immune system. Whether specific mutations are related with this, remains to be analyzed. To address this issue, three transformed glioma cell lines were obtained (Rb(-/-), Ras(V12), and Rb(-/-)/Ras(V12)) by in vitro retroviral transformation of astrocytes, as previously reported. In addition, Ras(V12) and Rb(-/-)/Ras(V12) transformed cells were injected into SCID mice and after tumor growth two stable glioma cell lines were derived. All these cells were characterized in terms of Rb and Ras gene expression, morphology, proliferative capacity, expression of MHC I, Rae1delta, and Rae1alphabetagammadeltaepsilon, mult1, H60a, H60b, H60c, as ligands for NK cell receptors, and their susceptibility to NK cell-mediated cytotoxicity. Our results show that transformation of astrocytes (Rb loss, Ras overexpression, or both) induced phenotypical and functional changes associated with resistance to NK cell-mediated cytotoxicity. Moreover, the transfer of cell lines of transformed astrocytes into SCID mice increased resistance to NK cell-mediated cytotoxicity, thus suggesting that specific changes in a tumor suppressor (Rb) and a proto-oncogene (Ras) are enough to confer resistance to NK cell-mediated cytotoxicity in glioma cells and therefore provide some insight into the ability of tumor cells to evade immune responses.Xunta de GaliciaComisión EuropeaInstituto de Salud Carlos IIIConsejo Nacional de Ciencia y Tecnologia (CONACyT)Consejo Nacional de Ciencia y Tecnologia (CONACyT)FOSSISXunta de Galicia/PXIB208091PRISCIII/CB158340ISCIII/CB180851FOSSIS/18236

Calidad de la dieta, evaluada por el Healty Eating Index-2010, y factores de obesidad asociados con el ejercicio: estudio transversal

Introduction: Certain weight management methods may be associated with unhealthy dietary intakes, skewing toward certain dietary components and lacking others. Management of weight should not ignore the quality of the diet, as both obesity and poor diet are associated with higher risk of chronic disease. Objective: To conduct a diet quality and exercise scan and observe their repercussion on BMI, in adults from Spain, Portugal, Uruguay and Mexico. Material and methods:An observational retrospective cohort study was designed, with 1181 adults aged 18-65 years. HEI-2010 score was used to assess diet quality. Data on type, days a week and hours/day of exercise, and participant’s anthropometric measures were collected.Results: The mean HEI-2010 score was 65.21. There were no statistically significant differences between HEI-2010 score and BMI [p=0.706], BMI and days of exercise per week [p=0.151], BMI and hours/day of exercise [p=0.590] and BMI and being active [>3 days/week] [p=0.106]. On the contrary, overall exercise influenced BMI significantly [p<0.001]. Conclusions: Dietary patterns may help to prevent weight gain and fight overweight and obesity. This study, however, did not observe associations between the quality of the diet nor specifics of exercise with lower BMIs. The quality of the diet of adults in Spain, Portugal, Uruguay and Mexico fell short of recommendations.Introducción: Ciertos métodos de control de peso pueden estar asociados con ingestas dietéticas poco saludables, inclinándose hacia ciertos componentes de la dieta y omitiendo otros. El manejo del peso no debe ignorar la calidad de la dieta, ya que tanto la obesidad como la mala alimentación están asociadas con un mayor riesgo de enfermedad crónica. Objetivo: Realizar un exploración de la calidad de la dieta y el ejercicio y observar su repercusión en el IMC, en adultos de España, Portugal, Uruguay y Méjico. Material y métodos: se diseñó un estudio observacional de cohorte retrospectivo, con 1181 adultos de 18 a 65 años. La puntuación HEI-2010 se utilizó para evaluar la calidad de la dieta. Se recopilaron datos sobre el tipo, días a la semana y horas/día de ejercicio, y las medidas antropométricas de los participantes. Resultados: La puntuación media del HEI-2010 fue de 65.21. No se encontraron diferencias estadísticamente significativas entre el puntaje HEI-2010 y el IMC [p = 0,706], el IMC y los días de ejercicio por semana [p = 0,151], las horas/día de ejercicio [p = 0,590] y si se es activo [>3 días/semana] [p = 0,106]. Por el contrario, el ejercicio influyó significativamente en el IMC [p <0,001]. Conclusiones: El control del peso/IMC, al comer menos calorías y hacer ejercicio, puede ser un componente útil en una estrategia de control de peso saludable que contribuya a mejorar la calidad de la dieta

Prevalence of Mild Cognitive Impairment in southern regions of Colombia

Background: Recent reports suggest that by 2050 there will be an increase of around 310% of cases affected by dementia in Latin American countries. A previous study in a Southern region reported one of the highest prevalences of dementia in Latin America. It is important to explore current prevalence rates of dementia risk conditions such as Mild Cognitive Impairment (MCI). Methods: a cross-sectional study recruited a community-dwelling sample of 823 adults from rural and urban areas of two Southern provinces of Colombia from 2020-2022. Participants were assessed with a neuropsychological protocol validated in Colombia. To obtain general and region-specific prevalence rates, age, sex, schooling, and socioeconomic level were considered and controlled for. Results: Most of the participants reported low education and socioeconomic level, the participation of women was higher. It was determined that the prevalence of MCI was 53.6%, with 56.6% in the province of Caquetá followed by 51.9% in the province of Huila. The amnestic MCI represented 42.6%, the multidomain amnestic was 16.55%, and the non-amnestic was 1.81%. Our participants reported comorbidities such as diabetes and hypertension. We also observed a relationship between exposure to pesticides and MCI. Conclusion: We observed one of the highest prevalences of MCI in Latin America reported to date. Variables such as age, gender, and education proved risk factors for MCI in the explored regions. Our findings are very much in line with recent studies that highlight the influence of non-canonical risk factors of dementia in underrepresented countries from Latin America

Cov-caldas: A new COVID-19 chest X-Ray dataset from state of Caldas-Colombia

The emergence of COVID-19 as a global pandemic forced researchers worldwide in various disciplines to investigate and propose efficient strategies and/or technologies to prevent COVID-19 from further spreading. One of the main challenges to be overcome is the fast and efficient detection of COVID-19 using deep learning approaches and medical images such as Chest Computed Tomography (CT) and Chest X-ray images. In order to contribute to this challenge, a new dataset was collected in collaboration with “S.E.S Hospital Universitario de Caldas” (https://hospitaldecaldas.com/) from Colombia and organized following the Medical Imaging Data Structure (MIDS) format. The dataset contains 7,307 chest X-ray images divided into 3,077 and 4,230 COVID-19 positive and negative images. Images were subjected to a selection and anonymization process to allow the scientific community to use them freely. Finally, different convolutional neural networks were used to perform technical validation. This dataset contributes to the scientific community by tackling significant limitations regarding data quality and availability for the detection of COVID-19. © 2022, The Author(s)

Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study

Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak. Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study. Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM. Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide

Canagliflozin and renal outcomes in type 2 diabetes and nephropathy

BACKGROUND Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium–glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to <90 ml per minute per 1.73 m2 of body-surface area and albuminuria (ratio of albumin [mg] to creatinine [g], >300 to 5000) and were treated with renin–angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of <15 ml per minute per 1.73 m2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes. Prespecified secondary outcomes were tested hierarchically. RESULTS The trial was stopped early after a planned interim analysis on the recommendation of the data and safety monitoring committee. At that time, 4401 patients had undergone randomization, with a median follow-up of 2.62 years. The relative risk of the primary outcome was 30% lower in the canagliflozin group than in the placebo group, with event rates of 43.2 and 61.2 per 1000 patient-years, respectively (hazard ratio, 0.70; 95% confidence interval [CI], 0.59 to 0.82; P=0.00001). The relative risk of the renal-specific composite of end-stage kidney disease, a doubling of the creatinine level, or death from renal causes was lower by 34% (hazard ratio, 0.66; 95% CI, 0.53 to 0.81; P<0.001), and the relative risk of end-stage kidney disease was lower by 32% (hazard ratio, 0.68; 95% CI, 0.54 to 0.86; P=0.002). The canagliflozin group also had a lower risk of cardiovascular death, myocardial infarction, or stroke (hazard ratio, 0.80; 95% CI, 0.67 to 0.95; P=0.01) and hospitalization for heart failure (hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P<0.001). There were no significant differences in rates of amputation or fracture. CONCLUSIONS In patients with type 2 diabetes and kidney disease, the risk of kidney failure and cardiovascular events was lower in the canagliflozin group than in the placebo group at a median follow-up of 2.62 years
