Evaluate patient demographic, care encounter, comorbidity, and clinical differences in Hmong and non-Hmong gout patients.
Using retrospective chart review, all inpatient encounters (Hmong vs non-Hmong) were reviewed from 2014 to 2017. Acute or chronic gout was the primary or secondary diagnosis for the encounter.
Hmong gout patients were on average 11 years younger than non-Hmong patients, but after adjustment for age, sex, and type of encounter, had similar rates of hypertension, diabetes, and heart disease. Hmong patients had significantly decreased renal function at time of presentation; the odds ratio of CKD for Hmong patients was 2.33 vs. 1.48 for non-Hmong patients (p<0.05), mean creatinine 3.3 mg/dL vs. 2.0 mg/dL (beta = 1.35, p<0.001) and GFR 44.8 mL/min vs 49.3 mL/min (beta = -6.95, p<0.001). Hmong gout patients were more likely to use emergency care vs. elective/ urgent care, less likely to be using medications for the treatment of gout prior to admission (32.3% vs. 58.2%), and the leentive care management of gout along with diabetes, hypertension, heart disease, and kidney disease.
Physical activity (PA) is important for body health. A few reports suggested that PA also influenced skin structure and components. Little data are available on the influence of PA on skin mechanical properties (SMP). Here, we investigated the relationship between PA and SMP.
Twenty-five healthy Japanese female subjects (31.0±3.3years) were enrolled in the study. To monitor the 24-hr pulse rate, a wrist watch-type pulse monitor was used. PA intensity was divided into five PA intensity zones (max, anaerobic, aerobic, fat combustion, and warm-up) by the pulse monitor. The average values of the time spent on each intensity for 70days were calculated. To measure SMP, a Cutometer was used at the end of the monitoring. R0 indicated the height of the maximal skin deformation, and R6 was the ratio between viscoelastic and elastic deformation.
R0 was positively correlated with the time spent in four of the five PA intensity zones (max, anaerobic, aerobic, and fat combustion), whereas R6 was negatively correlated with the time spent in these four PA intensity zones. The time of warm-up did not correlate with SMP.
These results suggest that habitual moderate-to-vigorous PA influences SMP.

Despite the availability of atomic structures of the protein components of cardiac muscle thin filaments, detailed insights into their dynamics and response to calcium are yet to be fully depicted. In this study, we used molecular dynamic simulations of the core domains of the cardiac muscle protein troponin to characterize the equilibrium dynamics of cardiac troponin's calcium-bound and calcium-free forms, with a focus on elements of cardiac muscle contraction activation and deactivation; that is, calcium binding to the calcium sensor troponin C domain (TnC) and the release of the switch region of the troponin inhibitory domain I (TnI) from TnC. The process of calcium binding to the TnC binding site is described as a three-step process commencing with calcium capture by the binding site residues, followed by cooperative residue interplay bringing the calcium ion to the binding site, and finally, calcium-water exchange. Furthermore, we uncovered a set of TnC-TnI inter-domain interactions, critical for TnC N-lobe hydrophobic pocket dynamics. Absence of these interactions allows the closure of the TnC N-lobe hydrophobic pocket while the TnI switch region remains expelled, whereas if the interactions are maintained the hydrophobic pocket remains open. Modification of these interactions may fine-tune the ability of the TnC N-lobe hydrophobic pocket to close or remain open, modulate cardiac contractility, and present potential therapy-relevant targets.
Retinitis pigmentosa is a heterogeneous group of inherited retinal diseases leading to progressive vision loss. It has been estimated that the etiology is still unclear in 22%-40% of cases, indicating that many novel pathogenic variations related to RP remain unidentified in many patients. In this study, our aim was to investigate the disease-causing variants and function of the variants in two Chinese families with non-syndromic autosomal dominant retinitis pigmentosa (adRP).
Clinical data and peripheral blood DNA samples were collected. Whole exome sequencing (WES) was conducted to screen for variations. Then, the expression of green fluorescent protein (GFP)-fused wild-type PRPF31 protein and its variants was evaluated via western blotting and GFP fluorescence detection in vitro.
Two novel heterozygous variants of PRPF31 (NM_015629.4) c.855+5G>A and c.849_855del (p.Pro284Ilefs*35) were identified respectively in two families. The variant c.855+5G>A is co-segregated with the disease in adRP-01 family. Nor-NOHA in vivo The pedigree analysis result for c.849_855del (p. Pro284Ilefs*35) shows an inheritance pattern with incomplete penetrance for adRP-02 family. The RT-PCR analysis shows the PRPF31 gene c.855+5G>A leading to the missing from the 997th to the 1405th positions of the PRPF31 gene (NM_015629.4) cDNA. The expressions of the mutant GFP-fused PRPF31 protein were not detected in HEK293 cells or Cos7 cells via western blotting and immunofluorescence.
Our findings identified two novel variants in PRPF31 in two Chinese families with adRP, expanding the mutational spectrum of this gene. Functional analysis reveals that these variants lead to the truncation of the PRPF31 protein.

We report here on the first cases of ASF in wild boar detected in Germany close to the border with Poland. In addition to the constant risk of ASF virus (ASFV) spread through human activities, movements of infected wild boar also represent a route of introduction. Since ASF emerged in Western Poland in November 2019, surveillance efforts, in particular examination of wild boar found dead, were intensified in the regions of Germany bordering with Poland. The first case of ASF in wild boar in Germany was therefore detected by passive surveillance and confirmed on 10 September 2020. By 24 September 2020, 32 cases were recorded. Testing of samples from tissues of carcasses in different stages of decomposition yielded cycle threshold values from 18 to 36 in the OIE-recommended PCR, which were comparable between the regional and national reference laboratory. Blood swabs yielded reliable results, indicating that the method is suitable also under outbreak conditions.
