The WSS values generated by the model had respectively peak and average values of 19.81N/cm

and 15.76±1.81N/cm

for the common carotid, 10.77N/cm

and 7.57±1.66N/cm

for the internal carotid, 11.51N/cm

and 8.05±1.65N/cm

for the external carotid, 37.55N/cm

and 26.55±6.62N/cm

for the carotid bifurcation, 1.39N/cm

and 3.13±1.34N/cm

for the carotid bulb. The model measurements matched doppler velocimetry measurements with <15% variation.

Model based WSS values were higher but comparable with doppler velocimetry measurements. The carotid bulb had low WSS and is therefore the segment highly disposed to atheromatous plaque formation.

Subject-specific mathematical models could be incorporated during cardiovascular scan work up for accurate WSS distribution and early prediction of possible atherosclerotic sites.

Many patients undergoing total pancreatectomy with islet autotransplant (TPIAT) for severe, refractory chronic pancreatitis or recurrent acute pancreatitis have a history of endoscopic retrograde cholangiopancreatography (ERCP). Using data from the multicenter POST (Prospective Observational Study of TPIAT) cohort, we aimed to determine clinical characteristics associated with ERCP and the effect of ERCP on islet yield.

Using data from 230 participants (11 centers), demographics, pancreatitis history, and imaging features were tested for association with ERCP procedures. Logistic and linear regression were used to assess association of islet yield measures with having any pre-operative ERCPs and with the number of ERCPs, adjusting for confounders.

175 (76%) underwent ERCPs [median number of ERCPs (IQR) 2 (1-4). ERCP was more common in those with obstructed pancreatic duct (p=0.0009), pancreas divisum (p=0.0009), prior pancreatic surgery (p=0.005), and longer disease duration (p=0.004). A greater number of ERCPs was associated with disease duration (p<0.0001), obstructed pancreatic duct (p=0.006), and prior pancreatic surgery (p=0.006) and increased risk for positive islet culture (p<0.0001). Mean total IEQ/kg with vs. without prior ERCP were 4145 (95% CI 3621-4669) vs. 3476 (95% CI 2521-4431) respectively (p=0.23). Adjusting for confounders, islet yield was not significantly associated with prior ERCP, number of ERCPs, biliary or pancreatic sphincterotomy or stent placement.

ERCP did not appear to adversely impact islet yield. When indicated, ERCP need not be withheld to optimize islet yield but the risk-benefit ratio of ERCP should be considered given its potential harms, including risk for excessive delay in TPIAT.

The aim of this study was to investigate the effect of bone mineral density (BMD) on bone histomorphological parameters and bone turnover markers (BTMs) following osteoporotic vertebral compression fracture (OVCF) and to determine the correlation between BMD and the percentage of middle height compression during the healing process.

A total of 206 patients with OVCFs were included in this study. Bone biopsy specimens were acquired during surgery. Blood samples were obtained to determine the serum concentrations of BTMs. The patients were divided into 2 groups according to BMD.

The concentrations of N-terminal propeptide of type I collagen (PINP) in the T-score ≤ -2.5 group (50.92 ± 12.78 ng/ml) were significantly lower than those in the T-score > -2.5 group (68.75 ± 28.66 ng/ml, p = 0.025) 3-6 mo after fracture. Moreover, the volume of necrotic bone in the T-score ≤ -2.5 group (15.15 ± 5.44%) was higher than that (1.67 ± 0.79%, p < 0.001) in the T-score > -2.5 group during the same period. BMD was statistically correlated with cancellous bone content (R

 = 0.761, p <0.001), PMHC (R

 = 0.85, p < 0.001), fibrous tissue volume (R

 = -0.376, p < 0.001), and necrotic bone content (R

 = -0.487, p < 0.001).

The healing process of OVCFs in the setting of low bone mass frequently occurs in the presence of decreased bone formation abilities, severe vertebral body height loss and a large amount of necrotic bone.

Biallelic variants in SLC12A6 have been reported as the cause of autosomal-recessive (AR) hereditary motor and sensory neuropathy with agenesis of the corpus callosum (HMSN/ACC). Here we identified an autosomal-dominant (AD) heterozygous mutation in SLC12A6 in a Chinese patient with intermediate CMT. The patient presented with slowly progressive distal muscle weakness and atrophy. Electrophysiological examination showed a mixed axonal/demyelinating neuropathy. Cognition and brain MRI were normal. A single heterozygous missense mutation c.620G>A (p.R207H) in exon 5 of SLC12A6 was identified as the likely pathogenic mutation by whole-exome sequencing consistent with two previously published cases. It affects evolutionarily highly conserved amino acid residue and is predicted to be deleterious by using in silico tools. Modelling of the mutant KCC3 cotransporter showed altered formation of hydrogen bonds and weakened interaction force between the mutated site and its surrounding amino acid residues. Our findings expand the genotypic and phenotypic spectrum associated with SLC12A6 mutations from AR-HMSN/ACC to AD-CMT. The differences in the inheritance pattern might be associated with a dominant-negative pathomechanism.

The increase in COVID-19 cases is generating fear and concern in society, which generates an emotional response that influences the adoption of health-related behaviors. The objective of the study is to design and validate the Scale of Worry for Contagion of COVID-19 (PRE-COVID-19).

The study had a descriptive cross-sectional design. The population were young people and adults who resided in the cities of Lima and Callao (Perú) during the declaration of the national health emergency due to the COVID-19 pandemic, during the period from March 16 to 27, 2020, who were recruited through a non-probability sample. The PRE-COVID-19, the WHO-Five Well-Being Index, the Generalized Anxiety Disorder Scale-2 and a single item were applied to measure the general perception of health. The scales were shared using a Google form through social networks. An internal consistency reliability analysis and structural equation models were performed, specifically confirmatory factor analysis. The recommendations of the Declaration of Helsinki and the principles that guide the ethical practice of online studies were followed.

Eight hundred and sixteen young people and adults from Lima and Callao (200 men and 616 women; mean age 28.40, SD 7.10) participated. The results show a one-dimensional model with satisfactory goodness-of-fit indices χ

(9)=52.00; CFI=0.99; RMSEA=0.09 [0.07, 0.12]; WRMR=0.85. The λ of the model were higher than 0.50 and the reliability had an excellent value (ω=0.90). Likewise, the convergent and discriminant validity is evident between PRE-COVID-19 and measures of anxiety, well-being and self-reported health.

The results indicate that the PRE-COVID-19 is a valid and reliable instrument to measure concern about the spread of COVID-19 and the emotional impact on people.

To evaluate the effects of transcranial direct current stimulation on pain and other symptoms of knee osteoarthritis.

We performed a single-blind randomized sham-controlled trial with two parallel arms in an outpatient clinic of physical medicine and rehabilitation at a teaching hospital. We randomized 54 patients, 30-70 years of age, with knee osteoarthritis into two groups. They had morning stiffness ≤ 30 min, knee pain ≥ 3 months, joint crepitus, and Kellgren-Lawrence grade 1 or 2 on radiographs. For the active stimulation we administered 2 mA current, 20 min for each session and for the sham group 30 s stimulation and 20 min no current. Using the 10/20 International EEG system, the anode was fixed over the contralateral primary motor cortex (C3 or C4), and the cathode was placed on the ipsilateral supraorbital region (Fp1 or Fp2), with respect to the included knee. The program was repeated once daily over 5 consecutive days. Both groups received acetaminophen. We assessed the patients before and afterfect.

This study aimed to evaluate the safety of applying zinc oxide nanoparticles (ZnO NPs) to pathological skin. SL-327 mouse The majority of previous studies confirmed the safety of applying ZnO NPs to normal skin. However, we know very little about the risks of using sunscreen, cosmetics and topical drugs containing ZnO NPs for individuals with skin diseases.

ZnO NPs passed through gaps between keratinocytes and entered stratum basale of epidermis and dermis in imiquimod-induced psoriasis-like skin lesions. Application of a ZnO NP-containing suspension for 3 connective days delayed the healing of the epidermal barrier; increased the expression levels of inflammatory cytokines; promoted keratinocyte apoptosis and disturbed redox homeostasis. In TNF-α-stimulated HaCaT cells, QNZ and JSH-23 (NFκB inhibitors) blocked ZnO NP-induced inflammation. JSH-23 and NAC (a precursor of cysteine) inhibited ZnO NP-induced nuclear translocation of p-NFκB p65, cysteine deficiency and apoptosis. Additionally, ZnO NPs decreased CD98 level in main pathway and failed to activate transsulfuration pathway in cysteine biosynthesis.

ZnO NPs can enter psoriasis-like skin lesions and promote inflammation and keratinocyte apoptosis through nuclear translocation of p-NFκB p65 and cysteine deficiency. This work reminds the public that ZnO NPs have harmful effects on the recovery of inflammatory skin diseases.

However, the specific pathogenesis of keloids is not yet fully understood and existing treatment strategies are unsatisfied. It is therefore urgent to explore new biomarkers associated with its progression for keloids. In this study, the microarray dataset GSE113620 was downloaded from the Gene Expression Omnibus (GEO) database to screen out the differential expression of miRNAs (DEMs). The DEMs with large variance were applied to construct a weighted gene co-expression network to identify miRNA modules that are closely relevant to keloid progression. It is worth noting that miR-424-3p in the blue module (r = 0.98, p = 1e-18) is considered to be the ultimate target most relevant to keloid progression through co-expressed network analysis. Subsequently, the results of molecular biology experiments determine that miR-424-3p targeting Smad7 significantly enhanced the ability of cell proliferation, migration and collagen secretion after transfection with miR-424-3p mimic, while the apoptosis rate was significantly reduced.
