To develop a deep learning-based method for simultaneous myocardium and pericardial fat quantification from coronary computed tomography angiography (CCTA) for the diagnosis and treatment of cardiovascular disease (CVD).

We retrospectively identified CCTA data obtained between May 2008 and July 2018 in a multicenter (six centers) CVD study. The proposed method was evaluated on 422 patients' data by two studies. The first overall study involves training model on CVD patients and testing on non-CVD patients, as well as training on non-CVD patients and testing on CVD patients. The second study was performed using the leave-center-out approach. The method performance was evaluated using Dice similarity coefficient (DSC), Jaccard index (JAC), 95% Hausdorff distance (HD95), mean surface distance (MSD), residual mean square distance (RMSD), and the center of mass distance (CMD). The robustness of the proposed method was tested using the nonparametric Kruskal-Wallis test and post hoc test to assess the equality o8 for pericardial fat and 0.96 for myocardium).

Due to the vast variety of underlying genetic mutations and the relatively low patient population, RCDs present additional challenges for diagnosis. Precision medicine may offer opportunities for designing patient-specific therapies in particular for carriers of variants with undetermined significance. Moreover, precision medicine strategies provide benefit to patients with "common" symptoms but carry in rare genetic variants. Induced pluripotent stem cells (iPSCs) present a state-of-the-art precision medicine approach which recently made contributions to the study of RCDs via patient-specific iPSC-derived cardiomyocytes (iPSC-CMs). Human iPSC-CMs are derived from a patient's somatic cells and thus recapitulate a personalized genomics background, serving as patient-specific disease models. In light of these advantages, iPSC-CMs evolved as an effective tool for modeling cardiac disease phenotypes and accurately evaluating the toxicity of potential therapeutic compounds. This review covers approaches for studying RCDs and iPSC-CM models generated so far for different RCDs, such as long QT syndrome (LQT), short QT syndrome (SQT), Brugada syndrome (BrS), arrhythmogenic right ventricular cardiomyopathy (ARVC), and other rare diseases accomplished by cardiac-related syndromes like Fabry disease (FD) and Marfan syndrome (MFS). This overview aims to aid better understanding of the utility of iPSC-CM models, their various features, and future prospects.Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with multiorgan involvement, including heart. Pericarditis-the most common cardiac manifestation-occurs in up to 50% of cases, resulting in positive treatment outcomes. Rarely, it evolves to hazardous complications. A 50-year-old woman with SLE in clinical remission, receiving hydroxychloroquine 400 mg/day, presented to us with severe chest pain and low-grade fever. Physical examination revealed a friction rub and decreased breath sounds at the right lung base. Laboratory evaluation demonstrated leukopenia, thrombocytopenia, low C4 levels, and high acute phase reactants. Chest X-ray exhibited cardiomegaly, calcified pericardium, and right pleural effusion, confirmed by CT scan. PPD skin test and IGRA were both negative. Pericardial fluid, blood, and urine cultures for bacteria and fungi, as well as Gram and Ziehl-Neelsen stains were negative. Serological tests for viruses were also negative. The patient was diagnosed with calcified constrictive pericarditis (CP) due to SLE. She was treated with cyclophosphamide and methylprednisolone pulses, without improvement. Her clinical condition deteriorated, developing signs and symptoms compatible with cardiac tamponade (TMP), which was confirmed by Doppler echocardiography. The patient underwent pericardiectomy. A dramatic response was noted and she was discharged with prednisone 50 mg/day and azathioprine 100 mg/day. Thus, we review and discuss the relevant literature of SLE cases with CP or TMP. When an SLE patient presents with CP, infectious causes should be excluded first. To the best of our knowledge, this is the only case of SLE and calcified CP leading to TMP, hence physicians should be aware of this complication.

The incidence rate of vitamin D deficiency is increasing throughout the world. We measured the incidence rate of vitamin D deficiency and fibroblast growth factor 23 (FGF23) levels in 12- to 13-year-old adolescents in Japan.

A total of 492 adolescents (247 boys and 245 girls) from Japanese community enrolled in this study. 25 hydroxyvitamin D (25(OH)D) was measured with radioimmunoassay. In the subjects with low 25(OH)D levels (≦ 20ng/ml), intact parathyroid hormone (iPTH), calcium (Ca), phosphorus (P), albumin (Alb), alkaline phosphatase (ALP) and FGF23 were measured.

25(OH)D levels were significantly lower in girls (20.9 ± 3.1ng/ml) than in boys (22.2 ± 3.3ng/ml) (p < 0.0001). Fifty-five boys (22.3%) and 83 (33.9%) girls showed vitamin D deficiency (< 20ng/ml). One-hundred eighty-six (75.3%) boys and 162 (66.1%) girls showed vitamin D insufficiency (≧ 20ng/ml, < 30ng/ml). In the subjects whose 25(OH)D levels were ≦ 20ng/ml, the levels of iPTH, Ca, P, Alb, ALP and FGF23 were 22.3 ± 9.0pg/ml, 9.5 ± 0.4mg/dl, 4.7 ± 0.6mg/dl, 4.6 ± 0.3g/dl, 920.8 ± 339.3U/l and 42.6 ± 26.0pg/ml, respectively. There was a significant negative association between serum 25(OH)D levels and iPTH [r =  - 0.290 (p < 0.0001)]. There was no significant association between serum 25(OH)D levels and FGF23.

We show that 28% of Japanese 12- to 13-year-old early adolescents suffer from vitamin D deficiency. Findings from this study indicate that vitamin D deficiency requires close oversight in public health during adolescence to ensure proper bone health.

The SOST gene, which encodes sclerostin, a member of Dan family glycoproteins, was originally identified as the gene responsible for two sclerosing bone dysplasias, sclerosteosis and van Buchem disease. Sclerostin is highly expressed by osteocytes, negatively regulates canonical Wnt signaling pathways by binding to low-density lipoprotein receptor-related protein (LRP) 5/6, and suppresses osteoblast differentiation and/or function. Romosozumab, a specific anti-sclerostin antibody, inhibits sclerostin-LRP5/6 interactions and indirectly activates canonical Wnt signaling pathways and bone formation. This review focuses on the mechanism of action of sclerostin and summarizes clinical studies that demonstrated the efficacy of romosozumab to increase bone mineral density and reduce osteoporotic fractures, as well as its cardiovascular safety.

Personality traits can play an important role in outcomes of different chronic disorders. We hypothesize that the pessary treatment outcomes in symptomatic pelvic organ prolapse (POP) can also be influenced by personality traits.

This prospective observational study included consecutive women with symptomatic POP seeking pessary treatment between December 2018 and January 2020. The personality profile was measured using the Eysenck Personality Questionnaire (EPQ-R) at baseline, and patient health-related quality of life (HRQoL) was measured using the Pelvic Floor Impact Questionnaire-7 (PFIQ-7) and the Pelvic Floor Distress Inventory (PFDI-20) at baseline and at 3months. The correlation between HRQoL and personality traits was investigated by means of linear regression.

In total, 213 patients were included, of which 163 patients (76.5%) achieved success by the 3-month follow-up. No significant differences were found in the EPQ scores between the successful and unsuccessful groups. The scores on both the PFIQ-7 and PFDI-20 correlated significantly with neuroticism and correlated inversely with extraversion at both baseline and the 3-month follow-up. The degree of improvement in PFIQ-7 and PFDI-20 scores was not associated with personality traits.

Our data indicate that neurotic and introverted women were more bothered by POP-related symptoms, although the improvement in symptoms was not significantly associated with personality traits after 3months of pessary treatment.

We sought to examine the change in utilization of the midurethral sling (MUS) for the treatment of stress urinary incontinence (SUI) after the 2011 US FDA communication regarding transvaginal mesh.

This is a retrospective cohort study evaluating surgical utilization of MUS at a managed care organization of 4.5 million patients from 2008 to 2016. The primary outcome was the change in utilization of synthetic mesh MUS before and after the July 2011 FDA communication. Secondary outcomes were the changes in surgeon level MUS utilization.

MUS procedures decreased from 131 to 116 per 100,000 adult women with a decrease of 11.5% from 2010 to 2012. Year over year utilization of MUS was rapidly increasing (p < 0.01) prior the FDA communication from 116 (in 2008) to 131 (in 2010) per 100,000 women and then significantly declined (p < 0.01) after its release from 135 (in 2011) to 75 (in 2016) per 100,000 women (13% increase vs 44% decrease). The number of surgeons performing MUS increased (p < 0.01) from 172/year to 186/year from 2008 to 2010 (Table 1). This decreased (p < 0.01) from 183/year to 121/year from 2011 to 2016.

MUS for SUI drastically declined after the FDA communication. Despite the 2011 FDA communication concerning only transvaginal mesh for pelvic organ prolapse, there was a significant decrease in MUS with synthetic mesh utilization. Our findings support the importance of continued long-term outcome data regarding the safety and efficacy of MUS and highlight the impact of the FDA warning on MUS utilization.
