Chlamydia trachomatis serotype A infections in the Amazon region of Brazil: prevalence, entry and dissemination

CONCLUSIONS: Specific seroreactivity not only accounts for the large extent of dissemination of C. trachomatis in the Amazon region of Brazil but also shows an expanded area of occurrence of serotype A outside the epidemiological settings previously described. Furthermore, these data suggest possible routes of Chlamydia introduction into the Amazon region from the massive human migration that occurred during the 1,700s.

Authors: Rombauts A, Abelenda-Alonso G, Cuervo G, Gudiol C, Carratalà J Abstract INTRODUCTION: Despite adequate antibiotic coverage, community-acquired pneumonia (CAP) remains a leading cause of hospitalization and mortality worldwide. It induces both a local pulmonary and a systemic inflammatory response, particularly significant in severe cases. The intensity of the dysregulated host response varies from patient to patient and has a negative impact on survival and other outcomes. AREAS COVERED: This comprehensive review summarizes the pathophysiological aspects of the inflammatory response in CAP, brie...

Authors: Hammerschlag MR, Sharma R Abstract INTRODUCTION: Azithromycin was recommended as the first-line therapeutic regimen for treatment of genital infections in men and women by the Centers for Disease Control in 1998. A series of studies of azithromycin for treatment of rectal chlamydial infection in men who have sex with men (MSM) found that azithromycin was significantly less effective than doxycycline. AREAS COVERED: Literature on treatment of rectal C. trachomatis from 2000 through May 2020 was searched using PubMed. Retrospective and observational studies were identified documenting the frequency and t...

Authors: Tamai H, Shingaki N, Ida Y, Shimizu R, Maeshima S, Okamura J, Kawashima A, Nakao T, Hara T, Matsutani H, Nishikawa I, Higashi K Abstract BACKGROUND: Although clinical use of sofosbuvir plus ribavirin has been approved for patients infected with genotype 2 hepatitis C virus, patients ≥ 75-years-old have not been included in previous clinical trials. AIM: To evaluate the real-world safety and efficacy of sofosbuvir plus ribavirin for elderly patients (≥ 75-years-old) compared to nonelderly patients, we conducted a post-marketing prospective cohort study. METHODS: We treated 265 patients with ge...

Authors: Yamaya T, Baba T, Hagiwara E, Ikeda S, Niwa T, Kitayama T, Murohashi K, Higa K, Sato Y, Ogura T Abstract Coronavirus disease 2019 (COVID-19) has been recognized as a worldwide pandemic. However, the clinical course of COVID-19 remains poorly characterized. Although some cases of pneumothorax have been reported, they all had pulmonary complications or were managed with mechanical ventilation. We herein report a case of pneumothorax that developed even though the patient had no pulmonary underlying diseases and had never been managed with mechanical ventilation. In the present case, a lung bulla was found on...

A nodule with a diameter of 19 mm was found in the right lung and diagnosed as lung squamous cell carcinoma. Anti-cancer treatments were not performed because of the presence of advanced interstitial pneumonia and chronic respiratory failure. Cyclosporine A was tapered to avoid suppression of anti-tumor immunity, ...

AbstractPurpose of ReviewWith increasing use of prosthetic valves to treat degenerative valvular heart disease (VHD) in an aging population, the incidence and adverse consequences of paravalvular leaks (PVL) are better recognized. The present work aims to provide a cohesive review of the available literature in order to better guide the evaluation and management of PVL.Recent FindingsDespite gains in operator experience and design innovation, significant PVL remains a significant complication that may present with congestive heart failure and/or hemolytic anemia. To date, clear consensus or guidelines on the evaluation and...

AbstractPurpose of ReviewLymphatic disorders have received an increasing amount of attention over the last decade. Sparked primarily by improved imaging modalities and the dawn of lymphatic interventions, understanding, diagnostics, and treatment of lymphatic complications have undergone considerable improvements. Thus, the current review aims to summarize understanding, diagnostics, and treatment of lymphatic complications in individuals with congenital heart disease.Recent FindingsThe altered hemodynamics of individuals with congenital heart disease has been found to profoundly affect morphology and function of the lymph...

AbstractPurpose of reviewHeart failure remains a major cause of morbidity and mortality despite advances in guideline directed medical and electrophysiologic device therapies. Valvular heart disease (VHD) is common in heart failure patients and independently associated with poor outcomes. This review provides an update in the rapidly evolving field of transcatheter heart valve interventions (THVI) in the management of heart failure.Recent findingsAortic stenosis (AS) may cause or worsen heart failure. Functional mitral regurgitation (FMR) and functional tricuspid regurgitation (FTR) occur secondary to heart failure and con...

AbstractPurpose of reviewAtrial fibrillation is the commonest sustained arrhythmia in rheumatic heart disease and is associated with significant morbidity and mortality. In this review, we discuss its epidemiology, natural course and management with special emphasis on recent developments in understanding and treatment of atrial fibrillation in rheumatic heart disease.Recent findingsUse of direct oral anticoagulants appears promising, especially in developing countries where regular coagulation monitoring is a challenge. Also, restoration and maintenance of sinus rhythm in rheumatic atrial fibrillation appear feasible and ...
