We designed this study to identify laboratory and radiological parameters, which could be useful to guide the clinician, in the evaluation of a suspected case of coronavirus disease 19 (COVID-19).
This retrospective, observational, single-center-study recruited patients with a suspect of COVID-19 data were extracted from electronic medical records using a standardized data collection form.
A total of 566 patients with suspect COVID-19 infection were enrolled (280 were COVID-19+). The COVID-19 population was characterized with bilateral-pneumonia, a lower count of neutrophil, lymphocyte and monocyte, a lower neutrophil to lymphocyte-ratio (NLR). Lower of platelet count, d-dimer, troponin I, and serum calcium were in COVID-19 patients. The occurrence of COVID-19 diagnosis increased, independently of other variables, with pneumonia (odds ratio [OR] 3.60; p < .001), neutrophil below normal range (OR 4.15; p < .05), lactate dehydrogenase (OR 2.09; p < .01) and sodium above normal range (OR 2.34; p < .01). In patients with possible respiratory acute affections we found a higher neutrophil, higher monocyte, a higher NLR and a more elevation in d-dimer. In the Sepsis group showed higher level of white blood cell, C-reactive protein, d-dimer, and procalcitonin.
Our study confirms that patients with COVID-19 have typical radiological and laboratory characteristics. The parameters highlighted in the study can help identify COVID-19 patients, also highlighting which are the main differential diagnoses to be made and the parameters that facilitate the differential diagnosis.

To identify a set of scientific, systematic and clinically applicable nursing-sensitive quality indicators for pernicious placenta previa (PPP).
A modified Delphi-Consensus Technique.
According to literature retrieval published between 2009-2019, 38 nursing-sensitive quality indicators were chosen and a questionnaire was designed. An online survey was conducted in 20 hospitals in China, and data of experts' opinions were collected and analysed by improved Delphi method.
38 nursing-sensitive quality indicators were identified. The response rates in the two rounds of expert consultation were 97.4% and 100%, and the authoritative coefficients were 0.89 and 0.92. The coefficients of variation ranged from 0.04-0.28. The nursing-sensitive quality indicators were successfully constructed based on the modified Delphi technique.

To assess the correlation of cognitive function with sleep stability and depressive-anxious symptoms in insomnia patients.
Twenty-two insomnia patients with cognitive impairment (insomnia-CI), 21 insomnia patients with normal cognition (insomnia-CN), and 15 matched healthy control subjects (HCs) were enrolled and completed neuropsychological tests, the Hamilton Depression and Anxiety Scales (HAMD and HAMA), the Epworth Sleepiness Scale, the Pittsburgh Sleep Quality Index (PSQI),the Insomnia Severity Index (ISI), and the cardiopulmonary coupling (CPC) examination. Ratios of high-frequency coupling (HFC), low-frequency coupling (LFC), and very low-frequency coupling (VLFC) measured by CPC analysis represent stable sleep, unstable sleep, and wake/rapid eye movement (REM) sleep, respectively.
The HAMD, HAMA, PSQI, and ISI scores were higher in the insomnia-CN patients than in the HCs (all p<.01). However, no differences were found in the HFC, LFC, and VLFC ratio between the HCs and insomnia-CN groups. Co wake/REM sleep ratio and more severe symptoms of depression and anxiety. CPC analysis can reflect the severity of insomnia.Amyloid light chain (AL) cardiomyopathy is the most malignant specific cardiomyopathy. According to international recommendations, it should be ruled out non-invasively using the serum free light chain (FLC) ratio and immunofixation electrophoresis in both serum and urine. Here, we report on a 69-year-old female patient with new-onset heart failure with mid-range ejection fraction. Cardiac imaging was highly suggestive of cardiac amyloidosis. Amyloid scintigraphy showed faint myocardial tracer uptake according to Perugini Score 1, but immunofixation was negative and the FLC ratio was normal, despite a slight increase in lambda FLCs. Endomyocardial biopsy revealed advanced myocardial lambda immunoglobulin light chain deposition. Clinically relevant extracardiac amyloid organ infiltration could not be detected. Conclusively, non-invasive testing can in rare cases fail to exclude isolated AL amyloid cardiomyopathy. We suggest that even slight increases in serum lambda or kappa FLCs should be considered abnormal in suspected cardiac amyloidosis if non-invasive testing delivers discrepant results.
A retrospective study was performed to investigate the relationship between blood pressure variability (BPV) and imaging features of single small infarction (SSI) on magnetic resonance imaging (MRI).
Two hundreds and five patients with SSI and 120 healthy subjects matched with age and sex as the control group were enrolled into this study. All subjects came from the Affiliated Hospital to Qingdao University and Qingdao Municipal Hospital from October 2011 to June 2016. Research subjects were classified into different groups. Blood pressure was measured once a day and recorded during the hospitalization period (7-10days). The followed up data of patients after discharging from hospital was collected from the follow-up records.
Twenty-four hours BPV (SBP

, DDBP
, DDBP
), day-to-day BPV (SBP
, SBP
, SBP
), and visit-to-visit SBP
in nonround lesion group were significantly higher than that in round group (p<.05). Compared with nondeep lesion group, some parameters in day-to-day BPV and visit-to-visit BPV were significantly higher in the deep small lesion group (p<.05).
Increased BPV parameters such as day-to-day and visit-to-visit (SBP
, SBP
, DBP
) were related to the SSI characterized by small lesion in deep brain region.

Previous studies on the association between inflammatory bowel disease (IBD) and stroke showed conflicting results.
Articles published before July 2020 were searched in databases (PubMed, Web of Science, Medline, EMBASE, and Google Scholar). We computed all multivariate odds ratios (ORs) or relative risks (RRs) and 95% confidence intervals (CI) by using STATA 12.0 software.
The meta-analysis indicated that IBD was associated with an elevated risk of stroke (OR/RR=1.21, 95% CI 1.08 to 1.34, I
=83.6%, p<.001). In addition, both Crohn's disease (CD) and ulcerative colitis (UC) were associated with a higher risk of stroke (CD OR/RR=1.25, 95% CI 1.03 to 1.52, I
=86.1%, p<.001; UC OR/RR=1.09, 95% CI 1.04 to 1.15, I
=54.7%, p=.051). see more Subgroup study showed that IBD was associated with a higher risk of stroke in cohort studies (RR=1.21, 95% CI 1.08 to 1.36, I
=85.0%, p<.001). Subgroup study showed that IBD was related to an elevated risk of stroke in both Caucasian and Asian groups (Caucasian group OR/RR=1.13, 95% CI 1.05 to 1.23, I
=44.6%, p=.094; Asian group OR/RR =1.36, 95% CI 1.07 to 1.74, I
=92.5%, p<.001).
IBD is a risk factor for stroke. More high-quality large-sample epidemiologic studies about the relationship between IBD and stroke should be further conducted.

Duchenne muscular dystrophy (DMD) is an X-linked recessive neuromuscular disorder characterised by progressive irreversible muscle weakness, primarily of the skeletal and the cardiac muscles. DMD is characterised by mutations in the dystrophin gene, resulting in the absence or sparse quantities of dystrophin protein. A precise and timely molecular detection of DMD mutations encourages interventions such as carrier genetic counselling and in undertaking therapeutic measures for the DMD patients.
In this study, we developed a 2.1Mb custom DMD gene panel that spans the entire DMD gene, including the exons and introns. The panel also includes the probes against 80 additional genes known to be mutated in other muscular dystrophies. This custom DMD gene panel was used to identify single nucleotide variants (SNVs) and large deletions with precise breakpoints in 77 samples that included 24 DMD patients and their matrilineage across four generations. We used this panel to evaluate the inheritance pattern of DMD mutations in maternal subjects representing 24 DMD patients.
Here we report our observations on the inheritance pattern of DMD gene mutations in matrilineage samples across four generations. Additionally, our data suggest that the DMD gene panel designed by us can be routinely used as a single genetic test to identify all DMD gene variants in DMD patients and the carrier mothers.

A complete understanding of these molecular processes requires analysis of chromatin context in vitro. Here, Drosophila four core histones were produced in a native and unmodified form using wheat germ cell-free protein synthesis. In the assembly reaction, four unpurified core histones and three chromatin assembly factors (dNAP-1, dAcf1 and dISWI) were incubated with template DNA. We then assessed stoichiometry with the histones, nucleosome arrays, supercoiling and the ability of the chromatin to serve as a substrate for histone-modifying enzymes. Overall, our method provides a new avenue to produce chromatin that can be useful in a wide range of chromatin research.
