As long as you are self-compassionate, you will never walk alone. The interplay between self-compassion and rejection sensitivity in predicting loneliness.

Research shows that one of the key predictors of loneliness is cognitive-affective attitude towards oneself. Until recently, researchers' interest in this area was focused mainly on self-esteem. Lately, however, researchers looking for the antecedents of loneliness turned their attention to a different self-attitude variable-namely, self-compassion. The aim of the current study was to extend the existing research on the self-compassion-loneliness link by investigating rejection sensitivity as a potential underlying mechanism and moderator of the relationship between these variables. A sample of 204 participants from Poland, aged 18-70 years (M = 28.36, SD = 9.19), completed a set of three questionnaires: the Self-Compassion Scale-Short Form, the Revised UCLA Loneliness Scale, and the Adult Rejection Sensitivity Questionnaire. The study revealed that rejection sensitivity was both a mediator and a moderator between self-compassion and loneliness. These results are discussed in the context of the cognitive-affective mechanisms of loneliness and the protective functions of self-compassion.

Non-calcific aortic tissue quantified from computed tomography angiography improves diagnosis and prognostication of patients referred for transcatheter aortic valve implantation.

AIMS: We aimed to investigate the role of aortic valve tissue composition from quantitative cardiac computed tomography angiography (CTA) in patients with severe aortic stenosis (AS) for the differentiation of disease subtypes and prognostication after transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: Our study included 447 consecutive AS patients from six high-volume centres reporting to a prospective nationwide registry of TAVI procedures (POL-TAVI), who underwent cardiac CTA before TAVI, and 224 matched controls with normal aortic valves. Components of aortic valve tissue were identified using semi-automated software as calcific and non-calcific. Volumes of each tissue component and composition [(tissue component volume/total tissue volume) × 100%] were quantified. Relationship of aortic valve composition with clinical outcomes post-TAVI was evaluated using Valve Academic Research Consortium (VARC)-2 definitions.High-gradient (HG) AS patients had significantly higher aortic tissue volume compared to low-flow low-gradient (LFLG)-AS (1672.7 vs. 1395.3 mm3, P < 0.001) as well as controls (509.9 mm3, P < 0.001), but increased non-calcific tissue was observed in LFLG compared to HG patients (1063.6 vs. 860.2 mm3, P < 0.001). Predictive value of aortic valve calcium score [area under the curve (AUC) 0.989, 95% confidence interval (CI): 0.981-0.996] for severe AS was improved after addition of non-calcific tissue volume (AUC 0.995, 95% CI: 0.991-0.999, P = 0.011). In the multivariable analysis of clinical and quantitative computed tomography parameters of aortic valve tissue, non-calcific tissue volume [odds ratio (OR) 5.2, 95% CI 1.8-15.4, P = 0.003] and history of stroke (OR 2.6, 95% CI 1.1-6.5, P = 0.037) were independent predictors of 30-day major adverse cardiovascular event (MACE). CONCLUSION: Quantitative CTA assessment of aortic valve tissue volume and composition can improve detection of severe AS, differentiation between HG and LFLG-AS in patients referred for TAVI as well as prediction of 30-day MACEs post-TAVI, over the current clinical standard.

Comparison of the short-term safety and efficacy of transcarotid and transfemoral access routes for transcatheter aortic valve implantation.

BACKGROUND: Transfemoral access is the preferred approach for transcatheter aortic valve implantation (TAVI), as it is characterized by the lowest complication rate. In the majority of patients ineligible for transfemoral access, the transcarotid approach can be used. AIMS: This study aimed to compare short­term outcomes in 2 groups of patients treated with transcarotid or transfemoral TAVI. METHODS: A retrospective comparison included 265 patients in whom the TAVI procedure was performed between 2017 and 2019 (transcarotid TAVI, n = 33; transfemoral TAVI, n = 232). Preoperative characteristics, procedural and postprocedural outcomes, as well as 30­day mortality were assessed. RESULTS: Compared with the transfemoral TAVI group,patients undergoing transcarotid TAVI presented with a higher New York Heart Association (NYHA) functional class (median [interquartile range (IQR)], 3 [3-3] vs 2 [2-3]; P <0.001), a higher surgical risk (median [IQR] EuroSCORE II, 6 [4.8-10.7] vs 4.8 [2.8-7.9]; P = 0.003), and a higher incidence of peripheral artery disease (36.4% vs 18.1%; P = 0.035). The median (IQR) procedure duration in the transcarotid TAVI group was shorter than in patients undergoing transfemoral TAVI (65 [60-80] min vs 90 [80-110] min; P <0.001, respectively). In both study groups, we noted a high percentage of procedural success (transcarotid vs transfemoral TAVI, 96.9% vs 97.2%; P = 0.66). We found no significant differences between transcarotid TAVI and transfemoral TAVI in terms of periprocedural and 30­day mortality as well as the number of strokes. Regardless of the access route chosen, echocardiographic parameters and the NYHA class similarly improved compared with preprocedural data. CONCLUSIONS: Despite posing a higher baseline risk and presenting a greater anatomic complexity, transcarotid access is safe and associated with 30­day outcomes similar to those observed for transfemoral access. Importantly, procedural time was short and no periprocedural strokes or vascular complications were reported.

Prospective registry on cerebral oximetry-guided transcarotid TAVI in patients with moderate-high risk aortic stenosis.

BACKGROUND: The aim of the study was to assess safety TAVI procedure through the common carotid artery in high-vascular-risk patients. METHODS: The approach was selected by a multidisciplinary (cardiologists and cardiac surgeons) heart team after analyzing preoperative coronary angiography, transthoracic echocardiography and multislice contrast computed tomography of the peripheral arteries. Patients with the following conditions were qualified to the transcarotid access: severe peripheral artery disease (stenotic, heavily calcified), tortuous or small diameter <6 mm iliofemoral arteries, descending and abdominal aortic disease. RESULTS: Ten transcarotid transcatheter aortic valve implantation procedures were performed in our hospital from September 2017 to May 2018. There were no in-hospital deaths or strokes. The procedural success rate defined as the implantation of the valve with no coronary obstruction and less than moderate paravalvular leak was 100%. Parameters of regional cerebral oximetry were symmetrical on the left and right side in all cases and only during rapid ventricular pacing transiently decreased below the value of 50%. Postoperative cerebrovascular complications and myocardial infarctions were not observed. Statistically significant reduction of the echocardiographic parameters (PGmax and PGmean, Vmax) were observed. Mild paravalvular leaks occurred in 4 patients. Additionally, the heart failure symptoms diminished after the procedure from a median class III to class II. In the 3-month follow-up, mortality is 10% (unknown cause of death of one patient). The mean NYHA class of the other patients is II. Echocardiographic parameters are comparable to postoperative day 4. CONCLUSIONS: The pilot registry showed the safety of transcarotid approach in patients with the anatomy precluding the transfemoral approach.

The clinical usefulness of assessing the concentration of cell adhesion molecules sVCAM-1 and sICAM-1 in the serum of women with primary breast cancer.

AIM OF THE STUDY: Assessment of the concentrations of the soluble forms of the cell adhesion molecules sVCAM-1 and sICAM-1 in serum of female breast cancer patients. These concentrations were assessed in relation to factors such as: age, clinical stage of disease, histological grade of malignancy, the status of the local axillary lymph nodes, and the size of the primary tumour. MATERIAL AND METHODS: A total of 103 patients with primary breast cancer, aged 29 to 89 years, were investigated. The control group consisted of 40 healthy women. The concentration of sVCAM-1 and sICAM-1 was assessed using an enzyme-linked immunosorbent assay (ELISA). RESULTS: The results of the study suggest that the level of sVCAM-1 and sICAM-1 in the serum of women with breast cancer was significantly higher than that seen in the serum of healthy women. A relationship between the level of adhesion molecules and the stage of clinical disease advancement was discovered. There was a correlation between the increasing concentrations of sVCAM-1 and sICAM-1 and with the aggressiveness of the disease. Significant differences were also found in the group of women with metastases to the axillary lymph nodes and women with no metastasis. Similar correlations were found between sVCAM-1 and sICAM-1 levels and the size of primary tumour. CONCLUSIONS: The results obtained suggest that the assessment of the soluble forms of sVCAM-1 and sICAM-1 may be useful indicators in the assessment of the clinical advancement of breast cancer.
