Preoperative evaluation in elective surgeries has been associated with successful surgical treatment. However, there is no solid scientific evidence that screening for coronary artery disease (CAD) reduces surgical risk. The aims of this study were to describe the frequency of inappropriate investigation of obstructive CAD induced by pre-anesthetic assessment in individuals without cardiovascular symptoms (candidates for low- to intermediate-risk surgeries) and to evaluate predictors of this conduct. We performed a retrospective evaluation of medical records of anesthesiology services from patients undergoing pre-anesthesia assessment between May 2015 and May 2016, including those with functional capacity ≥4 metabolic equivalents without a diagnosis of heart disease. A total of 778 medical records (47±16 years of age, 62.6% female) were studied. A private hospital performed 50.1% of the surgeries and 60.4% were of intermediate risk. Only 2.7% (95%CI 1.7-4.1%) were screened for CAD, and 91% of these requests were mediated by cardiology consultations performed during pre-anesthetic testing visits. Factors associated with screening for CAD were hypertension, diabetes, moderate systemic disease (ASA III), cardiac consultation, previous diagnosis of CAD, and admission to a private hospital. Independent predictors were private hospitals (OR 3.9; 95%CI 1.3-11.0), ASA III (OR 5.3; 95%CI 1.7-16.2), and hypertension (OR 3.8; 95%CI 1.5-9.8). The frequency of inappropriate requests for CAD screening in asymptomatic individuals without untreated systemic diseases was low in pre-anesthetic visits. Although infrequent, screening for CAD is more common in the private setting, in patients with poorer health status, and is usually prescribed during cardiology consultation.Infections caused by uncommon and resistant pathogens in unusual sites have been increasingly reported in medical literature. We describe four cases of rare cytological findings and clinical impact for patients. In the first case, Aspergillus sp and Pneumocystis jirovecii were observed in the bronchoalveolar lavage of a patient with severe systemic lupus. In the second and third cases, we describe the presence of Trichomonas sp and Strongyloides sp larvae in samples of pleural and peritoneal fluid, respectively. The fourth report is about a patient with a wrist subcutaneous nodule whose synovial aspiration and cytology revealed the presence of brown septate hyphae. The early identification of the infectious agent in the cytological examination was essential for the introduction and/or re-adaptation of therapy in the four cases described. Patients in this report were immunocompromised with severe comorbidities, conditions often associated with unfavorable clinical outcomes.MicroRNAs (miRNAs) have been indicated to be frequently dysregulated in various cancers and promising biomarkers for colon cancer. The present study aimed to assess the prognostic significance and biological function of miR-1273a in colon cancer. The expression levels of miR-1273a was estimated using quantitative real-time polymerase chain reaction. Kaplan-Meier survival curves and Cox regression analysis were used to evaluate the prognostic value of miR-1273a in patients of colon cancer. The effects of miR-1273a on cell proliferation, migration, and invasion were investigated by cell experiments. The expression of miR-1273a was downregulated in colon cancer tissues and tumor cell lines compared with the normal controls (all P less then 0.001). The aberrant expression of miR-1273a was associated with vascular invasion (P=0.005), differentiation (P=0.023), lymph node metastasis (P=0.021), and TNM stage (P=0.004). The patients with low miR-1273a expression had low overall survival compared with the patients with high miR-1273a expression (log-rank P=0.002). miR-1273a was detected to be an independent prognostic biomarker for patients. Furthermore, the results of cell experiments revealed that miR-1273a downregulation promoted, while miR-1273a upregulation suppressed the cell proliferation, migration, and invasion. In conclusion, all data indicated that a downregulated expression of miR-1273a predicted poor prognosis for colon cancer and enhanced tumor cell proliferation, migration, and invasion. Thus, we suggest that methods to promote miR-1273a expression may serve as novel therapeutic strategies in colon cancer.Assays based on the flow cytometry technique allow a convenient analysis of multiple cellular parameters; however, their results should be interpreted cautiously due to a strong impact of confounding factors. Different techniques in cell culturing such as either enzymatic or mechanic detachment of adherent cells can heavily influence the structure of the cell membrane or presence of the surface antigens leading to strong false positive signals, and finally, substantial experimental bias. TPH104m The aim of our study was to assess and compare the impact of cell harvesting methods (both enzymatic and non-enzymatic) on the apoptosis process and on the surface antigen cytometric analyses. We found significant differences in the quality of analysis in terms of the amount of detected surface markers determined by the detachment method. Our results demonstrated clearly how important it is to carefully choose the appropriate detachment method and may help to avoid mistakes in experiment planning. In conclusion, we recommend to adjust the detachment method to the type of analyzed markers (surface antigens or translocated phosphatidylserine).Herniorrhaphy is one of the most common surgical procedures, with an estimated 20 million operations performed annually worldwide. One of the common complications associated with this procedure is inguinodynia, defined as pain beyond three months after inguinal hernia surgery. In this review, we have addressed the main aspects of this complication with current articles, published in the last five years. Inguinodynia has a multifactorial nature and studies have shown that its development is related to the surgical technique and intrinsic factors of the patient that imply greater predisposition to this phenomenon. In this regard, it has been discussed which surgical techniques imply a lower incidence of this complication. Many studies have focused on understanding intrinsic features of each patient, both in physical and cognitive aspects, and how the approach of these factors can favor a better post-surgical recovery. The treatment of this condition is still challenging, and there are no established universal guidelines.
