To analyze the level of knowledge, attitude, and practice about COVID-19 among Chinese residents, noninterventional and anonymous survey was carried out with an online questionnaire. Among the survey respondents (n = 619), 59.9% were female, 61.1% were from 18 to 30 years of age, and 42.3% held an undergraduate's degree. The mean scores for each scale were as follows perceived knowledge (36.3 ± 6.1), attitude (29.4 ± 4.7), practice (44.1 ± 4.8), total score (109.7 ± 13.2), barrier (0.2 ± 0.7), and cognition and behavior change score (8.5 ± 1.4). Perceived knowledge, attitude, practice, total score, and cognition and behavior changes were significantly and positively correlated, whereas barrier was negatively correlated with those scales (P less then 0.001). Linear regressions revealed that those respondents who were medical professionals, civil servants, employees of state-owned enterprises and public institutions, and had relatively higher level of education were associated with a higher perceived knowledge score, attitude score, practice score, and total score. Higher mean cognition and behavior change score was associated with company employees (8.8 ± 1.3). More than half of the respondents (51.4%) were optimistic about the government's interventional measures. The respondents in China had good knowledge, positive attitude, and active practice toward COVID-19, yet, it is advisable to strengthen nationwide publicity and focus on the target undereducated population by means of We-Chat, microblog, website, and community workers for better control effect.COVID-19 is caused by SARS-CoV-2. Although pulmonary manifestations have been identified as the major symptoms, several hematological abnormalities have also been identified. This review summarizes the reported hematological abnormalities (changes in platelet, white blood cell, and hemoglobin, and coagulation/fibrinolytic alterations), explores their patho-mechanisms, and discusses its management. Common hematological abnormalities in COVID-19 are lymphopenia, thrombocytopenia, and elevated D-dimer levels. These alterations are significantly more common/prominent in patients with severe COVID-19 disease, and thus may serve as a possible biomarker for those needing hospitalization and intensive care unit care. Close attention needs to be paid to coagulation abnormalities, and steps should be taken to prevent these occurring or to mitigate their harmful effects. The effect of COVID-19 in patients with hematological abnormalities and recognized hematological drug toxicities of therapies for COVID-19 are also outlined.An outbreak of SARS-CoV-2 has led to a global pandemic affecting virtually every country. As of August 31, 2020, globally, there have been approximately 25,500,000 confirmed cases and 850,000 deaths; in the United States (50 states plus District of Columbia), there have been more than 6,000,000 confirmed cases and 183,000 deaths. We propose a Bayesian mixture model to predict and monitor COVID-19 mortality across the United States. The model captures skewed unimodal (prolonged recovery) or multimodal (multiple surges) curves. The results show that across all states, the first peak dates of mortality varied between April 4, 2020 for Alaska and June 18, 2020 for Arkansas. As of August 31, 2020, 31 states had a clear bimodal curve showing a strong second surge. The peak date for a second surge ranged from July 1, 2020 for Virginia to September 12, 2020 for Hawaii. The first peak for the United States occurred about April 16, 2020-dominated by New York and New Jersey-and a second peak on August 6, 2020-dominated by California, Texas, and Florida. Reliable models for predicting the COVID-19 pandemic are essential to informing resource allocation and intervention strategies. A Bayesian mixture model was able to more accurately predict the shape of the mortality curves across the United States than other models, including the timing of multiple peaks. However, given the dynamic nature of the pandemic, it is important that the results be updated regularly to identify and better monitor future waves, and characterize the epidemiology of the pandemic.
Several small studies reported increased prevalence and incidence of asymptomatic vertebral fractures in patients with non-functioning adrenal adenomas and adenomas with mild autonomous cortisol secretion. However, the risk of symptomatic fractures at vertebrae, and at other sites remains unknown. Our objective was to determine the prevalence and incidence of symptomatic site-specific fractures in patients with adrenal adenomas.
Population-based cohort study, Olmsted County, Minnesota, USA, 1995-2017.
Participants were the patients with adrenal adenoma and age/sex-matched referent subjects. Patients with overt hormone excess were excluded. Main outcomes measures were prevalence and incidence of bone fractures.
Of 1004 patients with adrenal adenomas, 582 (58%) were women, and median age at diagnosis was 63 years (20-96). At the time of diagnosis, patients had a higher prevalence of previous fractures than referent subjects (any fracture 47.9% vs 41.3%, P = 0.003, vertebral fracture 6.4% vs 3.6%, P = 0.004, combined osteoporotic sites 16.6% vs 13.3%, P = 0.04). Median duration of follow-up was 6.8 years (range 0-21.9 years). After adjusting for age, sex, BMI, tobacco use, prior history of fracture, and common causes of secondary osteoporosis, patients with adenoma had hazard ratio of 1.27 (95% CI 1.07-1.52) for developing a new fracture during follow up when compared to referent subjects.
Patients with adrenal adenomas have higher prevalence of fractures at the time of diagnosis and increased risk to develop new fractures when compared to referent subjects.
Patients with adrenal adenomas have higher prevalence of fractures at the time of diagnosis and increased risk to develop new fractures when compared to referent subjects.Recurrent pregnancy loss (RPL) is one of the most common complications of early pregnancy associated in most cases with local or systemic immune abnormalities such as the diminished proportion of regulatory T cells (Tregs). AZD1656 mw Mesenchymal stem cells (MSCs) have been shown to modulate the immune responses by de novo induction and expansion of Tregs. In this study, we analyzed the molecular and cellular mechanisms involved in Treg-associated pregnancy protection following MSCs administration in an abortion-prone mouse mating. In a case-control study, syngeneic abdominal fat-derived MSCs were administered intraperitoneally (i.p) to the DBA/2-mated CBA/J female mice on day 4.5 of pregnancy. Abortion rate, Tregs proportion in spleen and inguinal lymph nodes, Ho1, Foxp3, Pd1 and Ctla4 genes expression at the feto-maternal interface were then measured on day 13.5 of pregnancy using flow cytometry and quantitative RT-PCR, respectively. The abortion rate in MSCs-treated mice reduced significantly and normalized to the level observed in normal pregnant animals.
