Introduction: Strategies to address suboptimal weight loss after Roux-en-Y gastric bypass (RYGB) can be developed if at-risk patients are identified in advance. This study aimed to build a pre-surgery prediction nomogram for early prediction of insufficient weight loss (IWL) or weight regain (WR) after bariatric surgery in Chinese patients.
Methods: In this retrospective study, 187 patients with obesity and type 2 diabetes who underwent laparoscopic RYGB were followed yearly for 3 years. Suboptimal weight loss included IWL and WR. IWL was defined as a total weight loss percentage of <25% at 1 year postoperatively, and WR was defined as a maximum weight loss percentage of >20% at 3 years postoperatively. Multivariate logistic regression was performed to identify independent predictors and to establish a nomogram to predict the occurrence of suboptimal weight loss.
Results: Multivariate logistic regression revealed that male sex (OR 4.268, 95% CI: 1.413-12.890), body mass index (OR 0.816, 95% CI: 0.705-0.946), and glycated hemoglobin (OR 1.493, 95% CI: 1.049-2.126) were independent predictors of IWL/WR. The AUC value of the nomogram constructed from the above three factors was 0.781. The Hosmer-Lemeshow test showed that the model had a good fit (p = 0.143). The calibration curve of the nomogram is close to an ideal diagonal line. Furthermore, the decision curve analysis demonstrated the good net benefits of the model.
Conclusions: A nomogram based on pre-surgery factors was developed to predict postoperative IWL/WR. This provides a convenient and useful tool for predicting suboptimal weight loss before surgery.

Background: Co-existent pulmonary tuberculosis and lung cancer (PTB-LC) represent a unique disease entity often characterized by missed or delayed diagnosis. This study aimed to investigate the clinical and radiological features of patients diagnosed with PTB-LC.
Methods: Patients diagnosed with active PTB-LC (APTB-LC), inactive PTB-LC (IAPTB), and LC alone without PTB between 2010 and 2022 at our institute were retrospectively collected and 1:1:1 matched based on gender, age, and time of admission.

Future pandemic threats may be caused by novel coronaviruses and influenza A viruses. Here we show that when directly added to a cell culture, 12mer guanine RNA (G12) and its phosphorothioate-linked derivatives (G12(S)), rapidly entered cytoplasm and suppressed the propagation of human coronaviruses and influenza A viruses to between 1/100 and nearly 1/1000 of normal virus infectivity without cellular toxicity and induction of innate immunity. Moreover, G12(S) alleviated the weight loss caused by coronavirus infection in mice.

Introduction: Renuvion was the first FDA approved helium plasma device utilized for subdermal tissue heating to reduce skin laxity. The purpose of this study was to demonstrate that the use of Renuvion improves the outcomes, skin quality and reduces the edema faster after lipoabdominoplasty.
Materials And Methods: Patients with abdominal skin laxity after a weight loss of at least 20 kg, nonsmokers, without major comorbidities, with a minimum 2-year follow-up and standardized pre- and postoperative photographs were included in this study.
