776). The median duration of surgery was also comparable between the groups (22min, IQR 20-30 vs 25min, IQR 21-35; P = 0.233). Two postoperative complications in the new group and one in the reused group were recorded (4% vs 2%; P = 0.536). Surgeons' subjective assessment of the instrument did not reveal significant difference between the groups in all of the investigated categories.

The results of our study support the reuse of Harmonic scalpels especially in the settings where economic constraints might hamper access to minimally invasive surgery to a larger number of patients. Indisulam purchase The results obtained on laparoscopic appendectomy might not be reproducible to other more demanding surgical procedures.

However, studies addressing surveillance-bias and treatments as a possible confounder are lacking. This retrospective study compared the prevalence and risk of melanoma between 982 patients with MF, and 3,165 patients with psoriasis attending tertiary cutaneous-lymphoma/psoriasis clinics during 2009 to 2018. Melanoma was diagnosed in 47 patients with MF (4.8%; 43 early-stage) and in 23 patients with psoriasis (0.7%) (odds ratio 6.6, p  less then  0.0001). In 60% of patients, MF/psoriasis preceded melanoma diagnosis. Hazard ratio (HR) for a subsequent melanoma in MF vs psoriasis was 6.3 (95% confidence interval (95% CI) 3.4-11.7, p  less then  0.0001). Compared with the general population, melanoma standardized incidence ratios were 17.5 in patients with MF (95% CI 11.0-23.9, p  less then  0.0001), and 2.2 (95% CI 0.6-3.8, p = 0.148) in patients with psoriasis. Narrow-band ultraviolet B was not a contributory factor (HR 1.15, 95% CI 0.62-2.14, p = 0.66). These findings add evidence that patients with MF have a significantly higher risk of melanoma, not only compared with the general population, but also compared with patients with psoriasis. This comorbidity may be inherent to MF.Human epidermal keratinocytes sense the presence of human skin microbiota through pathogen recognition receptors, such as toll-like receptors, and induce innate immune and inflammatory events. In healthy epidermis there is an absence of inflammation despite the continuous presence of cutaneous microbes, which is evidence of an effective immune regulatory mechanism. The aim of this study was to investigate tumour necrosis factor alpha-induced protein 3 (TNFAIP3), a negative regulator of toll-like receptor and nuclear factor kappa B signalling pathways, and its role in these regulatory events. A broad spectrum of toll-like receptor ligands induced TNFAIP3 expression, as did live Cutibacterium acnes, which is involved in the pathogenesis of acne. Changes in bacterium-induced, dose-dependent TNFAIP3 expression were Jun kinase- and nuclear factor kappa B-dependent, and resulted in altered cytokine and chemokine levels in in vitro cultured human keratinocytes. In acne lesions, TNFAIP3 mRNA expression was elevated compared with non-lesional skin samples from the same individuals. These results suggest that TNFAIP3 may have a general role in fine regulation of microbiota-induced cutaneous immune homeostasis.
Cardiac involvement is a serious complication of idiopathic inflammatory myopathy (IIM). GDF-15 can predict the risk and the prognosis of cardiovascular disease, but its value is unclear in IIM.

To investigate the diagnostic value of GDF-15 for myocardial involvement in IIM.

A total of 77 IIM patients from May 2018 to August 2020 were included in this retrospective study. Of these, 43 patients underwent cardiac magnetic resonance (CMR) examination. There were 33 SLE patients and 16 healthy people were used as the control group. The concentration of GDF-15 of these groups was measured by ELISA.

There were significant differences in GDF-15 levels in patients with IIM, SLE and healthy controls (H = 45.291, P<0.001). GDF-15 levels were statistically significant different between IIM patients with the myocardial injury [1484.88(809.07 2835.50) pg/ml] and without myocardial injury [593.26(418.61 784.59) pg/ml, P=0.001]. After adjusted for age, renal function, the risk of myocardial injury in IIM patients increased an average of 0.3% by per increased unit of GDF-15 (odds ratio=1.003, 95% CI 1.000, 1.007). The level of GDF-15 was positively correlated with extra-cellular volume (ECV) (rs = 0.348, P=0.028). GDF-15 ≥ 929.505 pg/ml (area under the curve=0.856, 95% CI 0.744, 0.968) predicted myocardial injury in IIM with a sensitivity of 0.75 and specificity of 0.90.

GDF-15 could serve as a potential biomarker to predict myocardial injury in IIM patients.

Somatic mutations of the epigenetic regulators DNMT3A and TET2 causing clonal expansion of haematopoietic cells (clonal haematopoiesis; CH) were shown to be associated with poor prognosis in chronic ischaemic heart failure (CHF). The aim of our analysis was to define a threshold of variant allele frequency (VAF) for the prognostic significance of CH in CHF.

We analysed bone marrow and peripheral blood-derived cells from 419 patients with CHF by error-corrected amplicon sequencing. Cut-off VAFs were optimized by maximizing sensitivity plus specificity from a time-dependent receiver operating characteristic (ROC) curve analysis from censored data. 56.2% of patients were carriers of a DNMT3A- (N = 173) or a TET2- (N = 113) mutation with a VAF >0.5%, with 59 patients harbouring mutations in both genes. Survival ROC analyses revealed an optimized cut-off value of 0.73% for TET2- and 1.15% for DNMT3A-CH-driver mutations. Five-year-mortality was 18% in patients without any detected DNMT3A- or TET2 mutation (VAF < 0.5%), 29% with only one DNMT3A- or TET2-CH-driver mutations above the respective cut-off level and 42% in patients harbouring both DNMT3A- and TET2-CH-driver mutations above the respective cut-off levels. In carriers of a DNMT3A mutation with VAF ≥ 1.15%, 5-year mortality was 31%, compared with 18% mortality in those with VAF < 1.15% (P = 0.048). Likewise, in patients with TET2 mutations, 5-year mortality was 32% with VAF ≥ 0.73%, compared with 19% mortality with VAF < 0.73% (P = 0.029).

The present study defines novel threshold levels for clone size caused by acquired somatic mutations in the CH-driver genes DNMT3A and TET2 that are associated with worse outcome in patients with CHF.
