Novel non-coding sequences isolated upstream of the human IRS-2 gene are disclosed as markers for the prediction and/or diagnosis of IRS-2 related metabolic disorders or diseases, such as diabetes. The sequences also function as markers in a method and assay for evaluating the insulin regulating, i.e. insulin sensitizing or inhibiting properties of drug candidate substances, e.g. a method and assay for high throughput screening. The sequences and/or information derived therefrom can also be used for influencing the expression of the IRS-2 gene, e.g. in the therapy of IRS-2 related metabolic disorders, such as diabetes.
INTRODUCTION: Pediatric reduction mammoplasty has become increasingly common due to the obesity epidemic. While obesity remains the leading cause of macromastia leading to surgery, it may also be a risk factor for postoperative complications. This study examines the safety of pediatric reduction mammoplasty and the risk of obesity for complications following this procedure.
METHODS: The American College of Surgeons National Surgical Quality Improvement Program Pediatrics was queried to obtain all reduction mammoplasty cases from 2012 to 2020. Univariate and multivariate logistic regression analyses controlling for confounders were carried out to assess the relationship between body mass index (BMI) and rates of complication.
RESULTS: One thousand five hundred eighty-nine patients with the primary Current Procedural Terminology code 19318 were included in the final analysis. The mean age was 16.6 (SD, 1.1) years, and the mean BMI was 30.5 (SD, 6.2) lb/in2. Notably, 49% of the patients were obese, and 31% were overweight, while only 0.4% were underweight. Forty-three patients (2.7%) sustained a superficial surgical site infection (SSI) postoperatively. Other complications were less prevalent, including deep SSI (4 patients, 0.3%), dehiscence (11, 0.7%), reoperation (21, 1%), and readmission (26, 1.6%).Independent variables analyzed included age, sex, BMI, diabetes mellitus, American Society of Anesthesiologists (ASA) class, and operative time, of which only BMI and ASA class were found to be significantly associated with SSI on univariate analysis. On multivariate logistic regression while controlling for ASA class and the false discovery rate, there was a strong association between increasing rates of superficial SSI and increasing BMI (unit odds ratio, 1.05; 95% confidence interval, [1.01, 1.09]; P = 0.02). The OR indicates that for each 1-unit increase in BMI, the odds of SSI increase by 5%.
CONCLUSIONS: Complications following pediatric reduction mammoplasty are uncommon, demonstrating the safety of this procedure. High BMI was found to have a significantly higher risk for superficial SSI. Increased caution and infection prophylaxis should be taken when performing this operation on obese patients.
UVA exposure disturbs the metabolism of skin cells, often inducing oxidative stress and inflammation. Therefore, there is a need for bioactive compounds that limit such consequences without causing undesirable side effects. The aim of this study was to analyse in vitro the effects of the phytocannabinoids cannabigerol (CBG) and cannabidiol (CBD), which differ in terms of biological effects. Furthermore, the combined use of both compounds (CBG+CBD) has been analysed in order to increase their effectiveness in human skin fibroblasts and keratinocytes protection against UVA-induced alternation. The results obtained indicate that the effects of CBG and CBD on the redox balance might indeed be enhanced when both phytocannabinoids are applied concurrently. Those effects include a reduction in NOX activity, ROS levels, and a modification of thioredoxin-dependent antioxidant systems. The reduction in the UVA-induced lipid peroxidation and protein modification has been confirmed through lower levels of 4-HNE-protein adducts and protein carbonyl groups as well as through the recovery of collagen expression. Modification of antioxidant signalling (Nrf2/HO-1) through the administration of CBG+CBD has been proven to be associated with reduced proinflammatory signalling (NFκB/TNFα). Differential metabolic responses of keratinocytes and fibroblasts to the effects of the UVA and phytocannabinoids have indicated possible beneficial protective and regenerative effects of the phytocannabinoids, suggesting their possible application for the purpose of limiting the harmful impact of the UVA on skin cells.
In Korea, 5% of patients older than 65 years and 10% of patients older than 80 have a history of atrial fibrillation (AF), which is often associated with sudden death and stroke. Medication and percutaneous radiofrequency catheter ablation are commonly used treatment modalities. Pharmacotherapy is primarily symptomatic treatment; moreover, the effect of conversion to a normal rhythm is minimal, and mainly aimed at stabilizing heart rate. Catheter ablation is associated with a high incidence of recurrence in chronic AF, and it is difficult to treat left atrial appendage, thereby preventing discontinuation of anticoagulation therapy post procedure. Thoracoscopic ablation is known to be a less invasive and more effective modality to treat patients with chronic atrial fibrillation. However, anticoagulation therapy is mandatory in the early postoperative period due to intracardiac thromboembolism associated with atrial stunning despite conversion to a sinus rhythm and resection of the left atrial appendage. Further investigation would be required to assess the efficacy and safety of novel oral anticoagulants such as edoxaban compared to that of warfarin for stroke prevention during the early postoperative period (6 months) after a thoracoscopic procedure. The need to maintain a constant level of blood coagulation and the potential development of complications such as hemorrhages are drawbacks associated with the use of warfarin. While novel oral anticoagulants such as edoxaban do have a role in atrial fibrillation, data regarding their effectiveness and incidence of complications after arrhythmia surgery do not exist. In this study, we will compare warfarin and edoxaban with respect to safety and efficacy, after they are used for 6 months following thoracoscopic ablation in patients with chronic atrial fibrillation
The hedgehog (Hh) signaling pathway is a pathway which regulates patterning, growth and cell migration during embryonic development, but in adulthood is limited to tissue maintenance and repair. Mutational inactivation of the inhibitory pathway components leads to constitutive ligand-independent activation of the Hh signaling pathway, results in cancers such as basal cell carcinoma and medulloblastoma. Ligand-dependent activation of Hh signaling is involved in prostate cancer, pancreatic cancer, breast cancer and blood cancers. Therefore, inhibition of the aberrant Hh signaling represents a promising approach toward novel anticancer therapy. The invention provides novel molecules of formula I that inhibit hedgehog pathway signaling and provides therapeutic applications for the treatment of malignancies (basal cell carcinoma, medulloblastoma, glioblastoma, non-small cell lung cancer, prostate cancer, pancreatic cancer, blood cancers, mesenchymal cancers, etc.), prevention of tumor regrowth, sensitization of radio-chemo therapies, and other diseases (inflammation, fibrosis and immune disorders).
All patients will be assessed and managed according to the results of CT-FFR test, assuming they have no prespecified contraindications to CT coronary angiography. The result of the CT-FFR will be conveyed to the supervising physician within 24 hours and will be used to determine the subsequent management plan.
Non-thermal plasma (NTP) refers to an ionized gas composed of ions, electrons and other reactive agents. The anti-cancerous properties of NTP have been proven in vitro and in vivo. The 10-year local recurrence risk (LRR) in breast cancer patients after a breast conservation therapy (i.e., lumpectomy, typically followed by radiation therapy) is still as high as 15-20%. NTP could be used to further treat the tumor bed to reduce the LRR.

The primary objective of this clinical trial is to determine the safe and tolerable dose of NTP treatment following breast cancer lumpectomy. The secondary objectives are to assess the safety and tolerability of NTP and to assess the cosmetic effects of NTP treatment in patients with breast cancer. Our exploratory objective is to assess the impact of NTP treatment on cancerous and normal tissues. Patients are followed for 3 months after NTP treatment. The patients are divided into 3 groups: group A (n=3): NTP treatment of part of the tumor bed ex vivo. Group B (n=3): NTP treatment of part of the tumor bed in situ (all treated tissues are removed for analysis). Group C (n=6-24): dose escalation per "3+3 Design" up to a maximum dose level 3. NTP treatment of part of the tumor bed in situ (the treated parts of the tumor bed will not be excised, except a small portion for analysis).

The safety and tolerability of treatment will be evaluated by means of dose limiting toxicities, adverse events (AEs) and serious adverse events reports, physical examinations, and laboratory safety evaluations. AEs will be coded according to the CTCAE v5.0. The results will be tabulated to examine their frequency, grade, and relationship to study treatment. The results of laboratory assessments will be evaluated similarly. The number of patients with cosmetic alterations linked to the NTP treatment and type of alterations will be assessed through the quality of life questionnaires (questions on breast appearance and texture) and through the photo collection. This is the first clinical trail to study the safety and tolerability of NTP in an all breast-cancer patient group.
Patients that arrive for an initial evaluation for low back pain will be randomized to either receive the video education via an application (app) on a tablet computer, or usual care (which consists of information in the form of a handout but no further education prior to seeing the Primary Care Provider - PCP). To control for exposure to the tablet computer, subjects in both groups will use the tablet computer to fill out the self-reported outcome measures.

This will all take place while the patient is waiting to see their PCP, who will be blinded to the educational intervention that the patient received. After enrollment and completion of baseline outcome measures and surveys, the subject will be randomized to one of the 2 arms, receive the intervention, and then proceed to have their appointment with their PCP. The appointment with the PCP will proceed per usual care standards, with no additional research interventions. The subjects will be contacted for a follow-up at 1 and 6 months for assessment of self-reported outcomes measuring pain, function, and disability. The investigators will also abstract healthcare utilization from claims data and compare variables of healthcare use between both groups over the 6-month period following enrollment (radiographs, MRIs, prescription opioids, and specialty referrals).
Whole exome and whole genome sequencing (WGS) have expanded the ability to determine the genetic etiology of previously undiagnosed disorders. This study is a multicenter prospective cohort study to evaluate the emerging technology of sequencing for the management of fetuses with structural anomalies. The hypothesis is that a significant subset of fetal structural anomalies has a genetic etiology identifiable by sequencing and that prenatal knowledge of this information will improve perinatal care, reduce unnecessary diagnostic testing, reduce the cost of care, and improve quality of life for both the child and the family. The aims of this study are to investigate these multiple aspects of prenatal sequencing in a single study with an innovative integrated prospective design, which will permit a robust evaluation of the benefits and risks of delivering diagnostic and prognostic genetic testing results in a prenatal setting.

The study will determine, in a sequential population of pregnancies with selected fetal structural anomalies and a negative or non-causal chromosomal microarray (CMA), the frequency of pathogenic, likely pathogenic, and uncertain genomic variants identifiable by sequencing. To determine the impact of this information on clinical care, a control population of unsequenced pregnancies with similar structural anomalies will be prospectively recruited and the infants from both cohorts will be followed up to 1 year of age. This study component will evaluate differences in healthcare management and cost through discharge from hospital post-delivery, and perinatal and infant outcomes through 1 year of life. The educational, counseling and psychosocial impact of sequencing results during the prenatal period, in the nursery and through 1 year of life also will be evaluated. Since the analytical and clinical tools needed for the full translation of sequencing into care are still developing, optimization of bioinformatic tools to improve identification of pathogenic and likely pathogenic mutations associated with prenatal phenotypes of established disease genes will be investigated, as well as identification of new genes associated with presently undiagnosed fetal/neonatal phenotypes. This study will provide an in-depth evaluation of the prenatal diagnostic value of sequencing prior to its responsible introduction into practice and will provide independent data to guide its translation.
This study aimed to test the hypothesis that long-term and low-dose supplementation with an ethanol extract of Ecklonia stolonifera may confer protection against high-fat diet (HFD)-induced obesity in mice. Male C57BL/6J mice were divided into two groups, one of which was fed an HFD (40 kcal% fat) and the other an HFD+E. stolonifera (0.006%, w/w, ∼5 mg/kg body weight/day) for 16 weeks. E. stolonifera supplementation significantly reduced body weight from week 3 and until the end of the experiment. E. stolonifera-supplemented mice also exhibited lower fat mass (epididymal, perirenal, and mesenteric fat) and smaller adipocyte size than HFD control mice. The two groups displayed similar food intakes, but E. stolonifera markedly decreased lipogenesis and increased lipolysis and fatty acid oxidation in adipose tissue. Moreover, E. stolonifera significantly decreased plasma and hepatic lipid levels, hepatic lipid droplet accumulation, plasma aminotransferase levels, and liver weight by decreasing lipogenesis and increasing fatty acid oxidation. As E. stolonifera-supplemented mice showed improvements in hyperglycemia, insulin resistance, and inflammation, compared to control mice, it is possible that the beneficial effects of E. stolonifera on obesity might be associated with decreased inflammation and insulin resistance. Collectively, these results indicate that E. stolonifera could be used as a novel means of preventing and treating obesity and obesity-related metabolic disorders.
Tumor organoids and tumors-on-chips can be built by placing patient-derived cells within an engineered extracellular matrix (ECM) for personalized medicine. The engineered ECM influences the tumor response, and understanding the ECM-tumor relationship accelerates translating tumors-on-chips into drug discovery and development. In this work, we tuned the physical and structural characteristics of ECM in a 3D bioprinted soft-tissue sarcoma microtissue. We formed cell spheroids at a controlled size and encapsulated them into our gelatin methacryloyl (GelMA)-based bioink to make perfusable hydrogel-based microfluidic chips. We then demonstrated the scalability and customization flexibility of our hydrogel-based chip via engineering tools. A multiscale physical and structural data analysis suggested a relationship between cell invasion response and bioink characteristics. Tumor cell invasive behavior and focal adhesion properties were observed in response to varying polymer network densities of the GelMA-based bioink. Immunostaining assays and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) helped assess the bioactivity of the microtissue and measure the cell invasion. The RT-qPCR data showed higher expressions of HIF-1α, CD44, and MMP2 genes in a lower polymer density, highlighting the correlation between bioink structural porosity, ECM stiffness, and tumor spheroid response. This work is the first step in modeling STS tumor invasiveness in hydrogel-based microfluidic chips. STATEMENT OF SIGNIFICANCE: We optimized an engineering protocol for making tumor spheroids at a controlled size, embedding spheroids into a gelatin-based matrix, and constructing a perfusable microfluidic device. A higher tumor invasion was observed in a low-stiffness matrix than a high-stiffness matrix. The physical characterizations revealed how the stiffness is controlled by the density of polymer chain networks and porosity. The biological assays revealed how the structural properties of the gelatin matrix and hypoxia in tumor progression impact cell invasion. This work can contribute to personalized medicine by making more effective, tailored cancer models.
Background: Although there is a relatively better prognosis, the 5-year survival rate for early stage lung cancer (Stage I, II, IIIA) is still relatively low compared to those other types of cancer. These patients might suffer lots from the uncertainty and substantial disease and treatment related physical changes. How to provide a feasible OPD personalized supportive care program is important.

Purpose: Main purpose of the study: (1) Develop and construct the contents, related patient education materials and computerized systems of the three evidence and service-based lung cancer care programs, including (a) Control as usual care (UC), and (b) Computer Assisted OPD Personalized Supportive Care Program (COPSCCP) (will be developed and structured the contents and computer system in the first 4 months of this research project); and (2) Compare the effects of COPSCCP and care as usual on self-report quality of life (QOL), physical symptoms, lung function, Depression, Anxiety, fear of recurrence, Unmet Cancer Needs, recurrence rate. Each patient will be follow for 2 years. Patients with recurrence, metastasis will be dropped out from the study (and refer to medical oncology).

Method: Eligible patients will be newly diagnosed early stage lung cancer patients (patients in stage I, II, \& IIIA) who have received surgery. A 2-group randomized control trial (RCT) matching with cancer stages will be conducted. For the COPSCCP, patients will be intervened for 6 months from the first time during hospitalization of receiving surgery or before hospital discharge and then OPD intervention. Each patient will be followed 6 time points for 2 years (will be drop and refer to medical oncology while having recurrence, metastasis or death): baseline (pre-discharge from hospital) and 1, 3, 6, 12, and 24 months after discharge from hospital, T1-T6, respectively. The outcomes indicators will include: psychological variables, physical/disease variables, symptoms, lung function, and recurrence rate during 2 years. The estimated subjects would be 150 for each group, totally 300 subjects recruited in the beginning of the study. Results would be analyzed mainly by GEE and survival analysis. IRB approval will be received before the RCT. The investigator expects to develop and test the supportive cancer care interventions and generalize the interventions into the cancer care system after the study if prove good outcomes.
Patients receive oral therapeutic estradiol once daily on days 1-3, twice daily on days 4-7, and thrice daily on days 8-90. Beginning on day 98, patients receive oral exemestane once daily in the absence of disease progression or unacceptable toxicity. Also laboratory biomarker analysis and enzyme-linked immunosorbent assay will be taken for correlative studies.
Frailty is highly prevalent among patients with aortic stenosis (AS). Nonetheless, the impact of AS severity on frailty remains unclear. This study aimed to clarify the association between AS severity and frailty in this population.This retrospective study included consecutive patients with AS who were hospitalized as candidates for transcatheter aortic valve implantation (TAVI). The prevalence of frailty, N-terminal pro B-type natriuretic peptide (NT-proBNP) level, gait speed, and geriatric nutritional risk index (GNRI) were compared between patients with severe and those with very severe AS. We employed multiple logistic regression analysis to examine the association between AS severity and frailty.A total of 137 patients were included. The prevalence of frailty was not significantly different between the severe and very severe AS groups (31% versus 30%). Similarly, no significant differences between the groups were observed for gait speed and GNRI, whereas the NT-proBNP level was significantly higher in the very severe group than in the severe AS group (P < 0.01). In the multiple logistic regression analysis, AS severity was not associated with frailty; however, gait speed and GNRI showed significant association with frailty independently of age, sex, and heart failure (very severe AS: odds ratio [OR] 1.051, 95% confidence interval [CI] 0.439-2.517; low gait speed: OR 5.109, 95% CI 1.556-16.775; malnutrition: OR 2.841, 95% CI 1.145-7.049).These findings suggest that low-intensity exercise training and nutritional therapy may be necessary in addition to AS treatment for the management of frailty in this population.
