intestinal flora shifted to damage the structure of mesenteric lymph nodes, and oxidative stress was further aggravated, which in turn affected the integrity of the intestinal autoimmune function.Objective To investigate the spectrum of pathogens causing lung fungal disease diagnosed by histopathology through histochemical special staining, compared to the fungal culture results, and to further evaluate the diagnostic value of histochemical special staining in pulmonary fungal disease. Methods We performed a retrospective analysis of 187 cases of pulmonary fungal disease diagnosed by histopathology in Peking Union Medical College Hospital from 2001 to 2015 (including 92 cases with pulmonary resection or open lung biopsy, 33 with percutaneous lung biopsy and 62 ones with fiberoptic bronchoscopic lung biopsy). PFK15 All cases were treated with hexamine silver, PAS, mucus carmine and acid-fast staining in addition to conventional HE staining. The clinical records and the fungal culture results were reviewed. Results There were 103 male and 84 female patients, aged from 12 to 70 years [average (48±14) years]. There were 85 cases(45.5%) of pulmonary aspergillosis(including 60 cases of invasive infection and 25 cathologically but the lavage culture grew"candida", but the patient's blood cryptococcal antigen was positive. Conclusions Among patients with histopathological diagnosis of pulmonary fungal disease, pulmonary aspergillosis was the most common, followed by pulmonary cryptococcosis, pulmonary mucormycosis, pulmonary histoplasmosis, pulmonary candidiasis and pneumocystosis. A small number of cases could not be classified by histopathology through histochemical special staining. There was a high consistency in discovering fungal pathogens between pathological histochemical special staining and culture method, but 37% pulmonary fungal disease diagnosed by histopathology were culture negative. In practice, the role of histochemical special staining in diagnosing pulmonary fungal disease should be paid more attention.Objective To investigate the current status of the diagnosis and treatment of pulmonary cryptococcosis in respiratory medicine and improve the understanding of the clinical characteristics of HIV-negative pulmonary cryptococcosis in China. Methods A prospective multi-center open cohort study was designed to screen for pulmonary cryptococcosis in the general wards and intensive care units of the Department of Respiratory Diseases in 22 hospitals. The HIV-negative patients with positive cryptococcal etiological diagnosis based on smear culture, antigen detection and histopathology were enrolled in the study. The clinical data of enrolled patients were collected and analyzed. Results A total of 457 cases of pulmonary cryptococcosis were enrolled, among which 3.28% (15/457) were disseminated infections. The case fatality rate was 0.88% (4/457). The majority of the cases were diagnosed by histopathological examinations (74.40%, 340/457) and cryptococcus antigen detection (37.64%, 172/457). Patients with pulmonary mptoms, imaging features and infection types. Meanwhile, immunocompromised patients differed from immunocompetent patients in terms of clinical symptoms, physical signs, infection-related inflammation indicator levels, imaging features, serum cryptococcus antigen positive rate and prognosis. Conclusions The majority of cases of HIV-negative pulmonary cryptococcosis in China had no underlying disease or immunocompromised status, and the overrall prognosis was favorable. However, early diagnosis of HIV-negative pulmonary cryptococcosis remains challenging due to the complicated manifestations of the disease.We aimed to identify valid screening questions for adults regarding physical activity and dietary behaviours that (a) were correlated with BMI, (b) were deemed by patients and providers to be relevant to clinical care, and (c) have utility for longitudinal understanding of health behaviours in populations. The goal was to identify screening questions that could be implemented at annual health care visits. First, we identified dietary behaviour questions and solicited patient input. Next, we tested both physical activity and dietary behaviour questions in a large sample to test their potential utility. Finally, we used cognitive interviews with patients and physicians to narrow our assessment for clinical settings. We present a parsimonious and reliable six-question scale of physical activity and dietary behaviours for research settings, as well as a three-question scale for clinical settings. We demonstrate a robust relationship between these measures and obesity. Additionally, we present evidence that these measures may serve as a useful red flag for patients before they develop obesity. We provide a concise and useful tool for assessing patients' physical activity and dietary behaviours in a variety of research settings. We also highlight the importance of incorporating this tool into the clinical intake flow for inclusion in patients' Electronic Health Record.Multiple randomized controlled trials and many real-world evidence studies have consistently shown that non-vitamin K antagonist oral anticoagulants (NOACs) are preferable to vitamin K antagonists for thromboembolic stroke prevention in the majority of patients with atrial fibrillation (AF). However, their role in the management of patients with AF and comorbidities, as well as in other patient populations with a high risk of stroke, such as patients with prior embolic stroke of undetermined source (ESUS) and those with atherosclerosis, is less clear. There is now increasing evidence suggesting that NOACs have a beneficial effect in the prevention of stroke in patients with AF and comorbidities, such as renal impairment and diabetes. In addition, while studies investigating the efficacy and safety of NOACs for the prevention of secondary stroke in patients with a history of ESUS demonstrated neutral results, subanalyses suggested potential benefits in certain subgroups of patients with ESUS. One NOAC, rivaroxaban, has also recently been found to be effective in reducing the risk of stroke in patients with chronic cardiovascular disease including coronary artery disease and peripheral artery disease, further broadening the patient groups that may benefit from NOACs. In this article, we will review recent evidence for the use of NOACs across the stroke spectrum in detail, and discuss the progress and future prospects in the different stroke areas.
