The maternal gut microbiota can influence and be affected by the substantial physiological changes taking place during the periparturition period. However, little information is known about the changes in the maternal gut microbiota and hormonal variations during this period in nonmodel organisms. Tibetan antelope (Pantholops hodgsonii) provide a unique system to address this issue because their summer migration cycle is synchronized with the periparturition period. Here, we used fecal microbiota as a proxy of gut microbiota. We characterized fecal microbial community of female migratory Tibetan antelope in the late pregnancy and postpartum periods using 16S rRNA gene sequencing and quantified fecal glucocorticoids (GCs) and triiodothyronine (T3) metabolite concentrations through enzyme immunoassays to identify the associations between maternal gut microbiota and physiological changes related with reproduction. We found that the fecal microbiota of Tibetan antelope was dominated by Firmicutes and Bacteroideteod, likely reflecting the metabolic and immune system dynamics during the periparturition period. This study highlights the importance of integrating microbiota, hormones and migration pattern to study the reproductive health of wildlife. By establishing a baseline of the physiological changes during the migration/periparturition period, we can have a better understanding of the impacts of increasing human activities on the Tibetan Plateau on the reproductive health of Tibetan antelope. The aim of the study was to assess a relationship between the occurrence of rheumatoid arthritis (RA) and its selected clinical parameters, and left ventricular myocardial strain. Fifty-six subjects were qualified for the study 30 RA patients and 26 subjects without rheumatoid diseases. The study design included taking medical history, assessment of the disease activity using selected scales of activity, collecting samples of venous blood to assess selected laboratory parameters and the assessment of cardiac magnetic resonance (CMR). Using the feature tracking method, the following parameters of the left ventricular myocardial strain were assessed longitudinal strain (LS), radial strain (RS) and circumferential strain (CS). Regarding global values, peak LS and peak CS were statistically significantly lower in RA patients than in the control group. In the whole study group, the factors independently related to low global LS peaks were as follows occurrence of RA, occurrence of arterial hypertension, increased activity of antibodies against cyclic citrullinated peptide and increased concentration of neutrophil gelatinase-associated lipocalin. The occurrence of RA, occurrence of diabetes, tobacco smoking, higher activity of antibodies against cyclic citrullinated peptide and current use of methotrexate are the risk factors for low peak of global CS. The current use of steroids constitutes a protecting factor against low global CS peaks. In subjects with no clinically manifested cardiac damage, RA is associated with a deteriorated left ventricular systolic function assessed by left ventricular myocardial strain measured by CMR feature tracking.In subjects with no clinically manifested cardiac damage, RA is associated with a deteriorated left ventricular systolic function assessed by left ventricular myocardial strain measured by CMR feature tracking.Abdominal radiology as a field has historically played an important role in the training, research, and performance of image-guided procedures. With the emphasis on increased subspecialization and the more formal and rigorous interventional radiology training programs, the question of the future of image-guided procedures within abdominal radiology is explored. A survey conducted by the Cross-Sectional Interventional Radiology Emerging Technology Commission on members of the Society of Abdominal Radiology showed that image-guided procedures are overwhelmingly being performed by abdominal radiology groups, and the vast majority of programs are training their fellows in this regard. We explore some of the challenges radiology and health care in general may face should abdominal radiologists no longer perform procedures and outline strategies departments can employ to meet the needs of both abdominal and interventional radiologists. We describe the reorganization carried out during the COVID-19 outbreak at one of the stroke centers in Italy and report on the clinical features and procedural variables of stroke patients in need of endovascular treatment. From 1 March to 10 May 2020, we retrospectively analyzed data from stroke patients in need of urgent neurointerventional treatment. Clinical presentation, demographics, and clinical history were collected along with procedural variables (door-to-needle time, needle-to-mTiCi? time). https://www.selleckchem.com/ Each patient underwent a nasal swab (polymerase chain reaction test), clinical screening, and chest CT scan to assess the risk of SARS-CoV-2 infection. Technical success, procedural safety (including staff SARS-CoV-2 infection), and clinical outcome at discharge were retrieved. A comparison was made with the same patient population treated between 1 March and 10 May 2019 to highlight possible differences in the characteristics or outcomes of the patients. One hundred thirty-six ischemic stroke patients were admitted to our facility from 1 March to 10 May 2020. Of these, 12 patients (9%) were classified as "high risk" for SARS-CoV-2 infection. Radiological suspicion of COVID-19 was confirmed in all cases by pharyngeal swab. Five SARS-CoV-2 patients (42%) needed endovascular therapy. None of the staff members tested positive for IgG against SARS-CoV-2. Compared to the same period in 2019, an increase in the mean interval from the first symptoms to hospital arrival was observed (p< 0.05). Endovascular treatment of stroke presented several challenges during the COVID-19 outbreak. Within the hospital, special pathways can be used to maintain both procedural safety and procedural times.Endovascular treatment of stroke presented several challenges during the COVID-19 outbreak.
