The manipulation of cell-cell interactions promotes the study of multicellular behavior, but it remains a great challenge for programming multicellular assembly in complex reaction pathways with multiple cell types. Here we report a DNA reaction circuit-based approach to cell-surface engineering for the programmable regulation of multiple cell-cell interactions. The DNA circuits are designed on the basis of a stem-loop-integrated DNA hairpin motif, which has the capability of programming diverse molecular self-assembly and disassembly pathways by sequential allosteric activation. Modifying the cell surface with such DNA reaction circuits allows for performing programmable chemical functions on cell membranes and the control of multicellular self-assembly with selectivity. We demonstrate the selective control of targeting the capability of natural killer (NK) cells to two types of tumor cells, which show selectively enhanced cell-specific adaptive immunotherapy efficacy. We hope that our method provides new ideas for the programmable control of multiple cell-cell interactions in complex reaction pathways and potentially promotes the development of cell immunotherapy.Alveolar rhabdomyosarcoma (ARMS) arising in the corpus uteri is an extremely rare condition with exceptionally rapid progression and poor prognosis. Furthermore, ARMS is primarily diagnosed in the pediatric population. Cryptotanshinone order Due to rarity of the disease, there are no standard treatment guidelines. A 90-year-old woman was presented with a huge pelvic mass causing dyspnea and abdominal distension. The patient underwent debulking surgery and was diagnosed with uterine ARMS by fresh specimen biopsy. Despite intensive postoperative care, the patient died on the eighth postoperative day. Here, we report a case of uterine ARMS that will add to our understanding of this exceptionally rare type of tumor.
To determine the risk factors for occult endometrial atypia and malignancy in patients diagnosed with non-atypical endometrial hyperplasia (NEH) on endometrial biopsy.
All new cases of NEH diagnosed between April 2015 and March 2016 at KK Women's and Children's Hospital, who underwent hysterectomy as first-line treatment, were included in the study. Patients with a history of endometrial hyperplasia or malignancy were excluded from the study. Patient demographics (e.g., age, parity, body mass index [BMI]), medical history, and clinical presentation were obtained for analysis.
In total, 262 patients were diagnosed with NEH, of which 18.3% (n=48) underwent hysterectomy as first-line management. The average time to surgery was 77.0±35.7 days. All cases were diagnosed by dilation and curettage, and hysteroscopy. The mean age was 51 years, and the mean BMI was 26.9±5.8 kg/m2. Histology from the hysterectomy specimen showed 9 (18.8%) patients with atypical hyperplasia and 2 (4.2%) with grade 1, stage 1A endometrioid adenocarcinoma. Patients with higher grade final pathology had significantly lower median parity (1 vs. 2, P=0.039), higher mean BMI (30.1±6.5 vs. 25.9±5.3 kg/m2, P=0.033), and BMI ≥30 kg/m2 (54.5% vs. 13.5%, P=0.008, odds ratio 7.68), compared to patients whose final histology showed NEH or no residual hyperplasia.
Occult endometrial atypia and malignancy were found in 18.8% and 4.2% of patients with an initial diagnosis of NEH, respectively. High BMI and low parity were identified as significant risk factors for high-grade endometrial lesions in patients with NEH.

Previously developed prediction models for type 2 diabetes mellitus (T2DM) have limited performance. We developed a deep learning (DL) based model using a cohort representative of the Korean population.
This study was conducted on the basis of the National Health Insurance Service-Health Screening (NHIS-HEALS) cohort of Korea. Overall, 335,302 subjects without T2DM at baseline were included. We developed the model based on 80% of the subjects, and verified the power in the remainder. Predictive models for T2DM were constructed using the recurrent neural network long short-term memory (RNN-LSTM) network and the Cox longitudinal summary model. The performance of both models over a 10-year period was compared using a time dependent area under the curve.
During a mean follow-up of 10.4±1.7 years, the mean frequency of periodic health check-ups was 2.9±1.0 per subject. During the observation period, T2DM was newly observed in 8.7% of the subjects. The annual performance of the model created using the RNN-LSTM network was superior to that of the Cox model, and the risk factors for T2DM, derived using the two models were similar; however, certain results differed.
The DL-based T2DM prediction model, constructed using a cohort representative of the population, performs better than the conventional model. After pilot tests, this model will be provided to all Korean national health screening recipients in the future.

Coronavirus disease 2019 (Covid-19) is associated with immune dysregulation and hyperinflammation, including elevated interleukin-6 levels. The use of tocilizumab, a monoclonal antibody against the interleukin-6 receptor, has resulted in better outcomes in patients with severe Covid-19 pneumonia in case reports and retrospective observational cohort studies. Data are needed from randomized, placebo-controlled trials.
In this phase 3 trial, we randomly assigned patients who were hospitalized with severe Covid-19 pneumonia in a 21 ratio receive a single intravenous infusion of tocilizumab (at a dose of 8 mg per kilogram of body weight) or placebo. Approximately one quarter of the participants received a second dose of tocilizumab or placebo 8 to 24 hours after the first dose. The primary outcome was clinical status at day 28 on an ordinal scale ranging from 1 (discharged or ready for discharge) to 7 (death) in the modified intention-to-treat population, which included all the patients who had received at leantly better clinical status or lower mortality than placebo at 28 days.

The efficacy of interleukin-6 receptor antagonists in critically ill patients with coronavirus disease 2019 (Covid-19) is unclear.
We evaluated tocilizumab and sarilumab in an ongoing international, multifactorial, adaptive platform trial. Adult patients with Covid-19, within 24 hours after starting organ support in the intensive care unit (ICU), were randomly assigned to receive tocilizumab (8 mg per kilogram of body weight), sarilumab (400 mg), or standard care (control). The primary outcome was respiratory and cardiovascular organ support-free days, on an ordinal scale combining in-hospital death (assigned a value of -1) and days free of organ support to day 21. The trial uses a Bayesian statistical model with predefined criteria for superiority, efficacy, equivalence, or futility. An odds ratio greater than 1 represented improved survival, more organ support-free days, or both.
Both tocilizumab and sarilumab met the predefined criteria for efficacy. At that time, 353 patients had been assigned to to, treatment with the interleukin-6 receptor antagonists tocilizumab and sarilumab improved outcomes, including survival. (REMAP-CAP ClinicalTrials.gov number, NCT02735707.).

Due to inefficient respiratory control, newborns become prone to asynchronous thoracoabdominal (TA) movements. The present study quantitatively estimated the synchrony of TA in preterm and full-term newborns through an inertial and magnetic measurement units (IMMUs) system.
This cross-sectional study was conducted with 20 newborns divided into Preterm Group (PTG, n = 10) and Full-Term Group (FTG, n = 10). Each neonate had IMMUs placed on the sternum and near the umbilicus, thus the TA motion was estimated through the resultant inclination angles calculated using a sensor fusion filter. The respiratory incursions were also manually counted and video-recorded for two minutes, then used to validate a Matlab custom-written routine for their automatic identification. The respiratory cycles were used to calculate the phase change angle (φ) between the thoracic and abdominal compartments. Association between the manual and automatic methods were verified by Pearson's correlation and root mean squared errors (RMSE), and the comparison between the groups was performed through the Student's t test with α = .05.
The values of respiratory incursions measured by both methods showed a high association and low measurement error (r = .96, RMSE = 9.8, p < .001). The FTG presented a higher occurrence of TA synchrony (p = .049) while the PTG group presented a higher occurrence of TA asynchrony (p = .036). No difference was found between the groups regarding the paradoxical classification (p = .071).
The proposed method was valid to quantitatively assess the TA synchrony of hospitalized neonates. Preterm infants had a higher occurrence of the asynchronous respiratory pattern in comparison to full-term infants.

Chronic skin disease (CSD) often has devastating effects on the physiological, psychological and social aspects of patients, who must adapt to them. However, it is not clear how patients adapt, especially with regard to their psychosocial adaptation (PSA). This research explored a theoretical model of PSA among people with CSD.
Following constructivist grounded theory methodology, a qualitative study was undertaken between August 2018 and June 2019.
Observation and semi-structured interview were conducted with included participants (n=19). Data were iteratively coded and analyzed by constant comparison following the key stages of initial, focused, axial and theoretical coding until saturation was achieved.
When individuals face the impacts of disease, they try to adjust to adapt it. The findings showed the core category (self-cognitive) and the contributing categories (impacts of chronic skin disease, contextual factors, physiological experiences, psychological experiences, social experiences, and positive and negative psychosocial adaptations) of the PSA among people with CSD.
