RESUMO

Associations between dyslipidemia and metabolic dysfunction-associated steatotic liver disease (MASLD) have been reported. Previous studies have shown that the triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio may be a surrogate marker of MASLD, assessed by liver ultrasound. However, no studies have evaluated the utility of this ratio according to biopsy-proven MASLD and its stages. Therefore, our aim was to evaluate if the TG/HDL-C ratio allows for the identification of biopsy-proven MASLD in patients with obesity. We conducted a case-control study in 153 patients with obesity who underwent metabolic surgery and had a concomitant liver biopsy. Fifty-three patients were classified as no MASLD, 45 patients as metabolic dysfunction-associated steatotic liver-MASL, and 55 patients as metabolic dysfunction-associated steatohepatitis-MASH. A receiver operating characteristic (ROC) analysis was performed to assess the accuracy of the TG/HDL-C ratio to detect MASLD. We also compared the area under the curve (AUC) of the TG/HDL-C ratio, serum TG, and HDL-C. A higher TG/HDL-C ratio was observed among patients with MASLD, compared with patients without MASLD. No differences in the TG/HDL-C ratio were found between participants with MASL and MASH. The greatest AUC was observed for the TG/HDL-C ratio (AUC 0.747, p < 0.001) with a cut-off point of 3.7 for detecting MASLD (sensitivity = 70%; specificity = 74.5%). However, no statistically significant differences between the AUC of the TG/HDL-C ratio and TG or HDL-C were observed to detect MASLD. In conclusion, although an elevated TG/HDL-C ratio can be found in patients with MASLD, this marker did not improve the detection of MASLD in our study population, compared with either serum TG or HDL-C.

RESUMO

CONTEXT: Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by the intracellular lipid accumulation in hepatocytes. Excess caloric intake and high-fat diets are considered to significantly contribute to MASLD development. OBJECTIVE: To evaluate the hepatic and serum fatty acid (FA) composition in patients with different stages of MASLD, and their relationship with FA dietary intake and MASLD-related risk factors. METHODS: This was a case-control study in patients with obesity undergoing bariatric surgery at a University Hospital between January 2020 and December 2021. Participants were distributed in three groups: no MASLD (n = 26), steatotic liver disease (n = 33), and metabolic dysfunction-associated steatohepatitis (n = 32). Hepatic and serum FAs levels were determined by GC-MS. The nutritional status was evaluated using validated food frequency questionnaires. The hepatic expression of genes involved in FA metabolism was analyzed by RT-qPCR. RESULTS: The hepatic, but not serum, FA profiles were significantly altered in patients with MASLD compared to those without MASLD. No differences were observed in FA intake between the groups. Levels of C16:0, C18:1, and the C18:1/C18:0 ratio were higher, while C18:0 levels and C18:0/C16:0 ratio were lower in patients with MASLD being significantly different between the three groups. Hepatic FA levels and ratios correlated with histopathological diagnosis and other MASLD-related parameters. The expression of genes involved in the FA metabolism was upregulated in patients with MASLD. CONCLUSION: Alterations in hepatic FA levels in MASLD patients were due to an enhancement of the de novo lipogenesis in the liver.

RESUMO

OBJECTIVE: To compare the results of surgical treatment of midshaft clavicle fractures, treated with the technique of minimally invasive plate osteosynthesis (MIPO) with locking compression plate versus open reduction and internal fixation (ORIF) with locked plate. METHODS: Quasi-randomized comparative study, evaluating displaced midshaft clavicle fractures treated with MIPO versus ORIF, with procedures performed by a single surgeon. We evaluated patients at 12 months using the University of California at Los Angeles (UCLA) scale and radiographically at 8, 12, 26 and 52 weeks, in addition to describing complications. RESULTS: We evaluated 44 patients; 22 submitted to MIPO and 22 to ORIF. The median UCLA scores at 12 months were 35 in the ORIF group and 35 in the MIPO group (p = 0.712). All patients had fracture healing at 3 months (p > 0.999). The mean surgery time was 87.5 min in the ORIF group and 47.5 in the MIPO (p < 0.001) group. As complications, 1 suture dehiscence (4.5%), 2 protruding plates (9.1%) and 1 change in sensitivity around the surgical wound (4.5%) were observed in the MIPO group, while in the ORIF group, 15 changes in sensitivity (68.2%) and 3 hypertrophic scars (13.6%) were observed. The only complication that showed a difference between the groups was the change in sensitivity (p < 0.001). No cases of pseudarthrosis or failure of osteosynthesis were identified in either technique. CONCLUSION: This study demonstrated that the two treatments, ORIF and MIPO, are equally effective in the treatment of displaced middle third clavicle fractures. However, MIPO is superior to ORIF in regard to reduced surgical time and preservation of supraclavicular nerve sensitivity.

RESUMO

Thyroid dysfunction is a common endocrine disorder in the general population, with a reported prevalence of 10-15%. However, this rate is even higher in older adults, with an estimated prevalence of ≈25% in some populations. Since elderly patients usually present more comorbidities than younger individuals, thyroid dysfunction may carry a synergistic negative health impact, mainly due to increased cardiovascular disease risk. Moreover, thyroid dysfunction in the elderly can be more difficult to diagnose due to its subtle or even asymptomatic clinical presentation, and the interpretation of thyroid function tests may be affected by drugs that interfere with thyroid function or by the coexistence of several diseases. On the other hand, thyroid nodules are also a prevalent condition in older adults, and its incidence increases with age. The assessment and management of thyroid nodules in the ageing patient should take into account several factors, as risk stratification, thyroid cancer biology, patient´s overall health, comorbidities, treatment preferences, and goals of care. In this review article, we summarize the current knowledge on the pathophysiology, diagnosis, and therapeutic management of thyroid dysfunction in elderly patients and we also review how to identify and manage thyroid nodules in this population.

RESUMO

BACKGROUND: Oleocanthal and oleacein are olive oil phenolic compounds with well known anti-inflammatory and anti-oxidant properties. The main evidence, however, is provided by experimental studies. Few human studies have examined the health benefits of olive oils rich in these biophenols. Our aim was to assess the health properties of rich oleocanthal and oleacein extra virgin olive oil (EVOO), compared to those of common olive oil (OO), in people with prediabetes and obesity. METHODS: Randomised, double-blind, crossover trial done in people aged 40-65 years with obesity (BMI 30-40 kg/m2) and prediabetes (HbA1c 5.7-6.4%). The intervention consisted in substituting for 1 month the oil used for food, both raw and cooked, by EVOO or OO. No changes in diet or physical activity were recommended. The primary outcome was the inflammatory status. Secondary outcomes were the oxidative status, body weight, glucose handling and lipid profile. An ANCOVA model adjusted for age, sex and treatment administration sequence was used for the statistical analysis. RESULTS: A total of 91 patients were enrolled (33 men and 58 women) and finished the trial. A decrease in interferon-γ was observed after EVOO treatment, reaching inter-treatment differences (P = 0.041). Total antioxidant status increased and lipid and organic peroxides decreased after EVOO treatment, the changes reaching significance compared to OO treatment (P < 0.05). Decreases in weight, BMI and blood glucose (p < 0.05) were found after treatment with EVOO and not with OO. CONCLUSIONS: Treatment with EVOO rich in oleocanthal and oleacein differentially improved oxidative and inflammatory status in people with obesity and prediabetes.

RESUMO

We demonstrate how resonant planar coils may be used as sensors to detect and quantify magnetic nanoparticles reliably. A coil's resonant frequency depends on the adjacent materials' magnetic permeability and electric permittivity. A small number of nanoparticles dispersed on a supporting matrix on top of a planar coil circuit may thus be quantified. Such nanoparticle detection has application detection to create new devices to assess biomedicine, food quality assurance, and environmental control challenges. We developed a mathematical model for the inductive sensor response at radio frequencies to obtain the nanoparticles' mass from the self-resonance frequency of the coil. In the model, the calibration parameters only depend on the refraction index of the material around the coil, not on the separate magnetic permeability and electric permittivity. The model compares favourably with three-dimensional electromagnetic simulations and independent experimental measurements. The sensor can be scaled and automated in portable devices to measure small quantities of nanoparticles at a low cost. The resonant sensor combined with the mathematical model is a significant improvement over simple inductive sensors, which operate at smaller frequencies and do not have the required sensitivity, and oscillator-based inductive sensors, which focus on just magnetic permeability.

RESUMO

BACKGROUND: Cardiovascular disease is a major cause of morbidity and mortality in people with HIV. The detection of subclinical atherosclerosis through vascular ultrasound allows us to identify patients at an increased risk of cardiovascular disease as a primary prevention strategy; this test is not routine. Our objective is to identify predictors of subclinical atherosclerosis in a population with HIV. METHODS: People with HIV infection were selected for primary prevention and underwent carotid and femoral ultrasound to detect atheromatous plaques. Logistic regression analysis including vascular risk factors was performed to predict the presence of atherosclerosis. RESULTS: One hundred eighty-three patients were included, 54% of whom were smokers; the mean duration of HIV infection was 9.52 years, and all patients were undergoing antiretroviral treatment. Subclinical atherosclerosis was present in 62.29% of the patients; 83.32% had plaque in the carotid territory, 57.93% in the femoral territory and 25.6% in both vascular territories. Compared to those without atherosclerosis, patients with atherosclerosis were on average 5.35 years older (53.86 vs. 48.51, p < 0.001) and had a higher prevalence of smoking (63.23% vs. 39.12%, p = 0.020) and a CD4/CD8 ratio below 0.7 (44.23% vs. 29.02%, p = 0.043). A CD4/CD8 ratio lower than 0.3 was always associated with subclinical atherosclerosis (95% confidence interval (CI): 83.9-100%). The inclusion of smoking, the CD4/CD8 ratio and age in the logistic regression analysis led to a diagnostic yield of 72% measured by the area under the receiving operator characteristic (ROC) curve (95% CI: 64-80%). CONCLUSIONS: Tobacco use, age and a CD4/CD8 ratio below 0.7 allow prediction of the presence of subclinical atherosclerosis in primary prevention. A CD4/CD8 ratio below 0.3 was a diagnostic indicator of atherosclerosis in HIV patients undergoing primary prevention in our sample.

RESUMO

Introducción: La hemodiálisis continúa siendo la modalidad de terapia de reemplazo renal prevalente en el mundo. La disfunción de la fístula arteriovenosa para hemodiálisis tiene efectos negativos en el paciente y su calidad de vida, por lo que el acceso vascular funcional se necesita para un adecuado tratamiento de hemodiálisis en pacientes con enfermedad renal terminal. El mayor inconveniente del acceso vascular resulta su alta incidencia de oclusión trombótica, causada por la estenosis, la cual se inicia por lesiones hiperplásicas de la capa intimal del vaso. Una de las modalidades de tratamiento a nivel internacional es la trombólisis del acceso vascular trombosado de menos de 24 horas de evolución. Objetivo: Exponer los resultados obtenidos con la aplicación de la trombólisis percutánea del acceso vascular para hemodiálisis trombosado en paciente con enfermedad renal terminal. Presentación del caso: Paciente masculino de 52 años, con diagnóstico de trombosis aguda del acceso vascular para hemodiálisis por enfermedad renal terminal, de 5 días de evolución, con deterioro de su estado de salud por encontrarse subdializado y urémico, con agotamiento del acceso vascular global para hemodiálisis. Se utilizó el tratamiento fibrinolítico directo del acceso vascular percutáneo a 100 mil UI/hora de Heberquinasa® en 10 horas, con recuperación del latido, thrill y repermeabilización de la fístula para hemodiálisis. Conclusiones: El tratamiento fibrinolítico con Heberquinasa® permitió la recuperación del paciente con trombosis aguda del acceso vascular para hemodiálisis. Se evitaron complicaciones asociadas a la subdiálisis y/o colocación de catéter central, y se incorporó al paciente a su programa de hemodiálisis, con garantías para su calidad de vida(AU)


Introduction: Hemodialysis continues to be the prevalent renal replacement therapy modality in the world. Arteriovenous fistula dysfunction for hemodialysis has negative effects on the patients and their quality of life, so functional vascular access is needed for adequate hemodialysis treatment in patients with end-stage renal disease. The greatest drawback of vascular access is its high incidence of thrombotic occlusion, caused by stenosis, which is initiated by hyperplastic lesions of the intimate layer of the vessel. One of the treatment modalities at the international level is the thrombolysis of the thrombosed vascular access of less than 24 hours of evolution. Objective: To present the results obtained with the application of percutaneous thrombolysis of vascular access for thrombosed hemodialysis in patients with end-stage renal disease. Case presentation: Male patient of 52 years, with diagnosis of acute thrombosis of vascular access for hemodialysis due to end-stage renal disease, 5 days of evolution, with deterioration of his health state due to being sub-dialized and uremic, with exhaustion of the global vascular access for hemodialysis. Direct fibrinolytic treatment of percutaneous vascular access at 100 thousand IU/hour of Heberkinase® was used in 10 hours, with recovery of the heartbeat, thrill and repermeabilisation of the fistula for hemodialysis. Conclusions: Fibrinolytic treatment with Heberkinase® allowed the recovery of the patient with acute thrombosis from the vascular access for hemodialysis. Complications associated with sub-dialysis and/or central catheter placement were avoided, and the patient was incorporated into their hemodialysis program, with guarantees for their quality of life(AU)

RESUMO

Colorectal cancer (CRC) is the third most frequent malignancy and the second cause of cancer death worldwide. Several factors have been postulated to be involved in CRC pathophysiology, including physical inactivity, unhealthy dietary habits, obesity, and the gut microbiota. Emerging data suggest that the microbiome may play a key role in CRC prognosis and derived complications in patients undergoing colorectal surgery. On the other hand, dietary intervention has been demonstrated to be able to induce significant changes in the gut microbiota and related metabolites in different conditions; therefore, the manipulation of gut microbiota through dietary intervention may constitute a useful approach to improve perioperative dysbiosis and post-surgical outcomes in patients with CRC. In this article, we review the role of the gut microbiota in CRC surgery complications and the potential therapeutic modulation of gut microbiome through nutritional intervention in patients with CRC undergoing surgery.

RESUMO

PURPOSE: To assess the association between three different a priori dietary patterns adherence (17-item energy reduced-Mediterranean Diet (MedDiet), Trichopoulou-MedDiet and Dietary Approach to Stop Hypertension (DASH)), as well as the Protein Diet Score and kidney function decline after one year of follow-up in elderly individuals with overweight/obesity and metabolic syndrome (MetS). METHODS: We prospectively analyzed 5675 participants (55-75 years) from the PREDIMED-Plus study. At baseline and at one year, we evaluated the creatinine-based estimated glomerular filtration rate (eGFR) and food-frequency questionnaires-derived dietary scores. Associations between four categories (decrease/maintenance and tertiles of increase) of each dietary pattern and changes in eGFR (ml/min/1.73m2) or ≥ 10% eGFR decline were assessed by fitting multivariable linear or logistic regression models, as appropriate. RESULTS: Participants in the highest tertile of increase in 17-item erMedDiet Score showed higher upward changes in eGFR (ß: 1.87 ml/min/1.73m2; 95% CI: 1.00-2.73) and had lower odds of ≥ 10% eGFR decline (OR: 0.62; 95% CI: 0.47-0.82) compared to individuals in the decrease/maintenance category, while Trichopoulou-MedDiet and DASH Scores were not associated with any renal outcomes. Those in the highest tertile of increase in Protein Diet Score had greater downward changes in eGFR (ß: - 0.87 ml/min/1.73m2; 95% CI: - 1.73 to - 0.01) and 32% higher odds of eGFR decline (OR: 1.32; 95% CI: 1.00-1.75). CONCLUSIONS: Among elderly individuals with overweight/obesity and MetS, only higher upward change in the 17-item erMedDiet score adherence was associated with better kidney function after one year. However, increasing Protein Diet Score appeared to have an adverse impact on kidney health. TRIAL REGISTRATION NUMBER: ISRCTN89898870 (Data of registration: 2014).

RESUMO

Today, public health is one of the most important challenges in society. Cancer is the leading cause of death, so early diagnosis and localized treatments that minimize side effects are a priority. Magnetic nanoparticles have shown great potential as magnetic resonance imaging contrast agents, detection tags for in vitro biosensing, and mediators of heating in magnetic hyperthermia. One of the critical characteristics of nanoparticles to adjust to the biomedical needs of each application is their polymeric coating. Fatty acid coatings are known to contribute to colloidal stability and good surface crystalline quality. While monolayer coatings make the particles hydrophobic, a fatty acid double-layer renders them hydrophilic, and therefore suitable for use in body fluids. In addition, they provide the particles with functional chemical groups that allow their bioconjugation. This work analyzes three types of self-assembled bilayer fatty acid coatings of superparamagnetic iron oxide nanoparticles: oleic, lauric, and myristic acids. We characterize the particles magnetically and structurally and study their potential for resonance imaging, magnetic hyperthermia, and labeling for biosensing in lateral flow immunoassays. We found that the myristic acid sample reported a large r2 relaxivity, superior to existing iron-based commercial agents. For magnetic hyperthermia, a significant specific absorption rate value was obtained for the oleic sample. Finally, the lauric acid sample showed promising results for nanolabeling.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) is increasing in parallel with the rising prevalence of obesity, leading to major health and socioeconomic consequences. To date, the most effective therapeutic approach for NAFLD is weight loss. Accordingly, bariatric surgery (BS), which produces marked reductions in body weight, is associated with significant histopathological improvements in advanced stages of NAFLD, such as nonalcoholic steatohepatitis (NASH) and liver fibrosis. BS is also associated with substantial taxonomical and functional alterations in gut microbiota, which are believed to play a significant role in metabolic improvement after BS. Interestingly, gut microbiota and related metabolites may be implicated in the pathogenesis of NAFLD through diverse mechanisms, including specific microbiome signatures, short chain fatty acid production or the modulation of one-carbon metabolism. Moreover, emerging evidence highlights the potential association between gut microbiota changes after BS and NASH resolution. In this review, we summarize the current knowledge on the relationship between NAFLD severity and gut microbiota, as well as the role of the gut microbiome and related metabolites in NAFLD improvement after BS.

RESUMO

Introducción: Las oclusiones arteriales periféricas agudas de menos de 14 días y de causa embólica y trombótica están asociadas a una alta morbimortalidad. La trombólisis dirigida por catéter representa en la actualidad una modalidad de tratamiento efectivo para la oclusión de vasos distales infrageniculares, que históricamente ha tenido malos resultados mediante embolectomía convencional, debido a la oclusión preexistente de vasos colaterales y al daño mecánico al endotelio, que conlleva esta técnica tradicional. Se decidió presentar este caso por ser la primera vez que se practica esta modalidad de tratamiento en Cuba. Objetivo: Exponer los resultados obtenidos con la aplicación de la trombolisis fibrinolitica mediante catéter en un paciente afectado por trombosis arterial periférica aguda. Presentación del caso: Paciente masculino de 57 años de edad con diagnóstico de trombosis arterial aguda de la arteria poplítea del miembro inferior izquierdo, con más de 24 horas de evolución de la isquemia y del compromiso de la viabilidad de la extremidad. Se utilizó el tratamiento fibrinolítico, mediante infusión de 250 000 unidades de Heberkinasa® en tres horas y se logró la mejoría del nivel de amputación. Conclusiones: El tratamiento fibrinolítico con Heberkinasa® fue útil en el paciente tratado porque redujo el nivel de amputación en el paciente, que presentó isquemia irreversible y criterio inicial de amputación supracondílea alto, en la extremidad comprometida(AU)


Introduction: Acute peripheral arterial occlusions of less than 14 days and of embolic and thrombotic cause are associated with a high morbidity and mortality. Catheter-directed thrombolysis currently represents an effective treatment modality for the occlusion of infragenicular distal vessels, which has historically had poor results by conventional embolectomy, due to the pre-existing occlusion of collateral vessels and the mechanical damage to the endothelium, which this traditional technique entails. It was decided to present this case because it is the first time that this modality of treatment is practiced in Cuba. Objective: Present the results obtained with the application of fibrinolytic thrombolysis by catheter in a patient affected by acute peripheral arterial thrombosis. Case presentation: A 57-year-old male patient diagnosed with acute arterial thrombosis of the popliteal artery of the left lower limb, with more than 24 hours of evolution of ischemia and compromised viability of the limb. Fibrinolytic treatment was used, by infusion of 250,000 units of Heberkinase® in three hours and the improvement of the amputation level was achieved. Conclusions: Fibrinolytic treatment with Heberkinase® was useful in the treated patient because it reduced the level of amputation in the patient, who presented irreversible ischemia and initial criteria of high supracondylar amputation in the compromised limb(AU)

RESUMO

OBJECTIVE: We aimed to study the predictive factors for recovery of parathyroid function in hypoparathyroid patients after total thyroidectomy for thyroid cancer. METHODS: We designed a retrospective, multicentre and nation-wide analysis of patients with total thyroidectomy who were seen in twenty endocrinology departments from January to March 2018. We selected patients with histologically proven thyroid cancer and retrieved information related to surgical procedure and thyroid cancer features. Survival analysis and Cox regression analysis were used to study the relationship between these variables and the recovery of parathyroid function. RESULTS: From 685 patients with hypoparathyroidism at discharge of surgery, 495 (72.3%) recovered parathyroid function over time. Kaplan-Meier analysis showed that this recovery was significantly related to the presence of specialized surgical team (P<0.001), identification of parathyroid glands at surgery (P<0.001), papillary histopathology (P=0.040), and higher levels of postoperative calcium (Ca) (P<0.001) and parathyroid hormone (PTH) (P<0.001). Subjects with gross extrathyroidal extension (P=0.040), lymph node metastases (P=0.004), and surgical re-intervention after initial surgery (P=0.024) exhibited a significant risk of persistence of hypoparathyroidism. Multivariate Cox regression analysis showed that the significant and independent factors for recovery of parathyroid function were postoperative concentrations of Ca (P=0.038) and PTH (P=0.049). The presence of lymph node metastases was a negative predictor of recuperation of parathyroid function (P=0.042) in this analysis. CONCLUSION: In patients with thyroid cancer, recovery of parathyroid function after total thyroidectomy was directly related to postoperative Ca and PTH concentrations, and inversely related to lymph node metastases.

RESUMO

Non-alcoholic fatty liver disease (NAFLD), which approximately affects a quarter of the world's population, has become a major public health concern. Although usually associated with excess body weight, it may also affect normal-weight individuals, a condition termed as lean/non-obese NAFLD. The prevalence of lean/non-obese NAFLD is around 20% within the NAFLD population, and 5% within the general population. Recent data suggest that individuals with lean NAFLD, despite the absence of obesity, exhibit similar cardiovascular- and cancer-related mortality compared to obese NAFLD individuals and increased all-cause mortality risk. Lean and obese NAFLD individuals share several metabolic abnormalities, but present dissimilarities in genetic predisposition, body composition, gut microbiota, and susceptibility to environmental factors. Current treatment of lean NAFLD is aimed at improving overall fitness and decreasing visceral adiposity, with weight loss strategies being the cornerstone of treatment. Moreover, several drugs including PPAR agonists, SGLT2 inhibitors, or GLP-1 receptor agonists could also be useful in the management of lean NAFLD. Although there has been an increase in research regarding lean NAFLD, there are still more questions than answers. There are several potential drugs for NAFLD therapy, but clinical trials are needed to evaluate their efficacy in lean individuals.

RESUMO

The clinical characteristics of patients with postoperative hypoparathyroidism who recover parathyroid function more than 12 months after surgery have not been studied. We aimed to evaluate whether the intensity of replacement therapy with calcium and calcitriol is related to the late recovery of parathyroid function. We compared the demographic, surgical, pathological, and analytical features of two groups of patients: cases, i. e., late recovery patients (those who recover parathyroid function>1 year after thyroidectomy, n=40), and controls, i. e., patients with permanent hypoparathyroidism (n=260). Replacement therapy with calcium and calcitriol was evaluated at discharge of surgery, 3-6 months, 12 months, and last visit. No significant differences were found in clinical, surgical, pathological, or analytical characteristics between cases and controls. The proportion of cases who required treatment with calcium plus calcitriol at 12 months was significantly lower than that found in controls (p<0.001). Furthermore, daily calcium and calcitriol doses in controls were significantly higher than those in cases at 3-6 months (p=0.014 and p=0.004, respectively) and at 12 months (p<0.001 and p=0.043, respectively). In several models of logistic regression analysis therapy with calcium and calcitriol at 12 months was negatively related to late recovery of parathyroid function. Although delayed recuperation of parathyroid function after total thyroidectomy is uncommon (13%), follow-up beyond 12 months is necessary in patients with postoperative hypoparathyroidism, especially in those whose needs of treatment with Ca and calcitriol are reducing over time.

RESUMO

The aim of this longitudinal study was to determine whether a rowing training program improved the quality of life and the physical activity levels in female breast cancer survivors (n = 28) (stage 1-4.54%; stage 2-36.36%; stage 3-54.54%; and stage 4-4.54%), diagnosed 4.68 ± 3.00 years previously, who had undergone a subsequent intervention (preservation 56.53% and total mastectomy 43.47%) and had a current mean age of 52.30 ± 3.78 years. The participants (n = 28) engaged in a 12-week training program, each week comprising three sessions and each session lasting 60-90 min. The short form of the International Physical Activity Questionnaire (IPAQ-SF) and the Short Form 36 Health Survey (SF-36) were also administered. The results showed statistically significant improvements in levels of physical activity and in the dimensions of quality of life. We can conclude that a 12-week rowing training program tailored to women who have had breast cancer increases physical activity levels, leading to improved health status and quality of life.

RESUMO

Colorectal cancer (CRC) is the third leading cause of cancer death and the fourth most common cancer in the world. Colonoscopy is the most sensitive test used for detection of CRC; however, their procedure is invasive and expensive for population mass screening. Currently, the fecal occult blood test has been widely used as a screening tool for CRC but displays low specificity. The lack of rapid and simple methods for mass screening makes the early diagnosis and therapy monitoring difficult. Extracellular vesicles (EVs) have emerged as a novel source of biomarkers due to their contents in proteins and miRNAs. Their detection would not require invasive techniques and could be considered as a liquid biopsy. Specifically, it has been demonstrated that the amount of CD147 expressed in circulating EVs is significant higher for CRC cell lines than for normal colon fibroblast cell lines. Moreover, CD147-containing EVs have been used as a biomarker to monitor response to therapy in patients with CRC. Therefore, this antigen could be used as a non-invasive biomarker for the detection and monitoring of CRC in combination with a Point-of-Care platform as, for example, Lateral Flow Immunoassays (LFIAs). Here, we propose the development of a quantitative lateral flow immunoassay test based on the use of magnetic nanoparticles as labels coupled to inductive sensor for the non-invasive detection of CRC by CD147-positive EVs. The results obtained for quantification of CD147 antigen embedded in EVs isolated from plasma sample have demonstrated that this device could be used as a Point-of-Care tool for CRC screening or therapy monitoring thanks to its rapid response and easy operation.
