Background: HPV primary screening has shown effectiveness for cancer prevention; however, gynaecological examination is considered uncomfortable. Self-sampling methods increase the acceptance of screening. The aim of this study is to compare the sensitivity and specificity of clinician sampling versus vaginal and urine self-sampling for HPV diagnosis. Methods: A diagnostic test study was conducted in a rural parish of Cuenca, Ecuador. A total of 120 women participated. Each participant self-collected urine and vaginal samples and underwent clinician sampling for HPV testing. The latter was considered as the golden standard. All three samples were processed with the same amplification and hybridization protocol for HPV detection (Hybribio) following the manufacturer’s instructions. Results: Characteristics of the participants were: median age 35 years; 40.8% married; 46.7% had a primary level of education; and median age of sexual onset, 17.6 years. The prevalence of any type of HPV with clinician sampling was 15.0%, 17.5% with urine sampling and 18.3% with vaginal self-sampling. Self-sampling sensitivity reached 94.4% (IC 74.2–99.9), and specificity 92.1% (IC 85.2–95.9). Urine sampling had a sensitivity of 88.8% (IC 67.2, 96.9), and specificity 94.1% (IC 67.2–96.9). The negative predictive value was 98.9% (IC 94.2–99.8) for vaginal self-sampling and 97.6% (IC 92.6–99.4) for urine sampling. Conclusions: This study shows that vaginal and urine self-sampling methods have similar sensitivity and specificity compared with clinician sampling for the diagnosis of HPV. The correlation between HPV genotypes among the three tests is satisfactory.

Inflammation is a key feature of atherosclerosis. The inflammatory process is involved in all stages of disease progression, from the early formation of plaque to its instability and disruption, leading to clinical events. This strongly suggests that the use of anti-inflammatory agents might improve both atherosclerosis progression and cardiovascular outcomes. Colchicine, an alkaloid derived from the flower Colchicum autumnale, has been used for years in the treatment of inflammatory pathologies, including Gout, Mediterranean Fever, and Pericarditis. Colchicine is known to act over microtubules, inducing depolymerization, and over the NLRP3 inflammasome, which might explain its known anti-inflammatory properties. Recent evidence has shown the therapeutic potential of colchicine in the management of atherosclerosis and its complications, with limited adverse effects. In this review, we summarize the current knowledge regarding colchicine mechanisms of action and pharmacokinetics, as well as the available evidence on the use of colchicine for the treatment of coronary artery disease, covering basic, translational, and clinical studies.

Background Today, cancer ranks as one of the leading causes of death. Despite the large number of novel available therapies, radiotherapy (RT) remains as the most effective non-surgical method to cure cancer patients. In fact, approximately 50% of all cancer patients receive some type of RT and among these 60% receive RT-treatment with a curative intent. However, as occurs with any other oncological therapy, RT treated patients may experience toxicity side effects that range from moderate to severe. Among these, cardiotoxicity represents a significant threat for premature death. Current methods evaluate cardiotoxic damage based on volumetric changes in the Left Ventricle Ejected Fraction (LVEF). Indeed, a 10% drop in LVEF is commonly used as indicator of cardiotoxicity. More recently, a number of novel techniques have been developed that significantly improve specificity and sensitivity of heart’s volumetric changes and early detection of cardiotoxicity even in asymptomatic patients. Among these, the Strain by Speckle Tracking (SST) is a technique based on echocardiographic analysis that accurately evaluates myocardial deformation during the cardiac cycle (ventricular and atrial function). Studies also suggest that Magnetic Resonance Imaging (MRI) is a high-resolution technique that enables a better visualization of acute cardiac damage. Methodology This protocol will evaluate changes in SST and MRI in cancer patients that received thoracic RT. Concomitantly, we will assess changes in serum biomarkers of cardiac damage in these patients, including: high-sensitivity cardiac Troponin-T (hscTnT), N-Terminal pro-Brain Natriuretic Peptide (NTproBNP) and Circulating Endothelial Cells (CECs), a marker of endothelial dysfunction and vascular damage. Discussion The presented protocol is to our knowledge the first to prospectively and with a multimodal approach, study serological and image biomarkers off early cardiac damage due to radiotherapy. With a practical clinical approach we will seek early changes that could potentially be in the future be linked to clinical mayor events with consequences for cancer survivors.

Radiotherapy (RT) is an essential part of breast cancer (BC) treatments. Unfortunately, heart exposure to radiation can also impair the long-term survival of patients. Our study aimed to quantify the oncological benefit and the cardiovascular (CV) risk associated with modern RT in a real-world cohort of BC patients. Our descriptive study enrolled BC patients who received adjuvant RT. Ten-year overall survival (OS) was estimated using Predict® version 2.1 (National Health Service, London, UK). The basal risk of CV events was estimated using the American Heart Association (ACC/AHA) CV score. Treatment volumes and mean cardiac doses were obtained from RT treatment plan records. The increased risk of CV events due to RT was estimated using a model proposed by Darby. The risk of acute myocardial infarction or stroke mortality was estimated using HeartScore® (European Society of Cardiology, Brussels, Belgium). A total of 256 BC patients were included in the study. The average age of patients was 57 years old (range: 25–91); 49.6% had left BC. The mean cardiac dose was 166 cGy (interquartile range (IQR) 94–273); the estimated hazard ratio (HR) for CV disease was HR 1.12 (confidence interval (CI) 1.04–1.24). The estimated baseline 10-year CV risk was 5.6% (0.2 to 51.2); CV risk increased by 0.9% (range 0.02–35.47%) after RT. The absolute risk of 10-year mortality from CV disease was 2.5% (0.1–9); RT was associated with an estimated 4.9% survival benefit (3.73–6.07) against BC death and a 0.23% (0.17–0.29) estimated increase in CV mortality. Modern RT decreased 10-year BC mortality by 4% but increased CV mortality by 0.2% in this cohort. Our findings encourage the implementation of personalized adjuvant RT treatments that balance risks and benefits to improve long-term BC patient survival.

Introduction: Colorectal cancer is the second leading cause of cancer-related death in the US; complete surgical resection is the only curative treatment for non-metastatic colorectal cancer (NMCC). Postoperative ileus (POI) frequently increases patient morbidity and healthcare costs. Enhanced recovery after surgery (ERAS) protocol is the standard of care in most institutions and has been shown to reduce postoperative complications, but there is no a completely effective treatment for this condition. Studies suggest that electroacupuncture (EA) can improve gastrointestinal tract function after surgery. Objective: We aim to determine if including EA to the standard treatment of POI decreases the time to the first defecation, enhancing the return of normal bowel function after colon resection for NMCC. Methods: We propose a phase II, single-center, randomized, triple-blinded, sham-controlled trial with two parallel arms and a 1:1 allocation ratio. Patients 40-80 years of age diagnosed with NMCC scheduled to undergo laparoscopic surgery for colon cancer resection will be included. The arms will be EA + standard treatment and sham EA + standard treatment. The standard treatment will follow the ERAS protocol. Discussion: This will be the first randomized clinical trial to evaluate the impact of using EA along with the ERAS protocol for POI. This intervention may reduce patient morbidity and improve healthcare costs associated with the disease.

Background: Cervical cancer screening has demonstrated high effectiveness reducing cervical cancer mortality worldwide, however there is still a high rate of under screened women. Pap smear technique is often considered an uncomfortable examination technique that can reduce uptake of the examination. This study explores the perceptions of self sampling and urine sampling versus traditional pap smear in rural settings of Cuenca Ecuador.Methods A qualitative study with a phenomenological approach was performed. Focus groups were conducted in El Valle parish of Azuay province of Cuenca Ecuador. Women natives of this rural area were included in this research. Results A total of 45 women, have participated in 7 focus groups, all participants live in rural area. Pap smear technique is considered a painful, intrusive and embarrassing method, however participants believe that is more reliable, compared with self sampling methods, due a direct visualization of the cervix and because other problems could be detected during the examination. Advantages of self-sampling include that it is perceived as comfortable, less painful, participation rate, time-saving, because it can be done at home, and can be made widely available for example through pharmacies or with help of traditional healers . Barriers are related with doubts of the quality of the sample and lack of capability to perform it. Conclusions This study shows that women consider self sampling methods as a possible solution to overcome barriers that could reduce the uptake of cervical cancer screening; privacy, comfortability and accessibility are major advantages of those methods. Self examination at home reduces waiting times in health centers, with high demand of attention or during Covid pandemic. Barriers are mainly related with doubts in the self proficiency to perform the test and the accuracy of the results. Those doubts are understandable, because self sampling methods are never used before in Ecuador, and could be solved with an adequate training and information for the patients. Further studies that measure acceptability and sensitivity in real application are required to address the utility of self sampling methods in a rural context.
