Abstract
BACKGROUND Low quality of life (QoL) in patients with non-small cell lung cancer (NSCLC) receiving adjuvant chemotherapy after radical resection is a major global health issue. High-quality evidence for the effectiveness of Shenlingcao oral liquid (SOL) as a complementary treatment in this patients is lacking at present. PURPOSE To determine whether complementary SOL treatment in NSCLC patients receiving adjuvant chemotherapy would yield greater improvements in QoL than chemotherapy alone. STUDY DESIGN We conducted a multicenter, randomized controlled trial of stages IIA-IIIA NSCLC patients undergoing adjuvant chemotherapy in seven hospitals. METHODS Using stratified blocks, participants were randomized in a 1:1 ratio to receive SOL combined with conventional chemotherapy or conventional chemotherapy alone. The primary outcome was the change in global QoL from baseline to the fourth chemotherapy cycle, and intention-to-treat analysis was applied with a mixed-effect model. Secondary outcomes were functional QoL, symptoms, and performance status scores at the 6-month follow-up. Missing data were handled with multiple imputation and a pattern-mixture model. RESULTS Among 516 randomized patients, 446 (86.43%) completed the study. After the fourth chemotherapy cycle, in comparison with the control group, patients receiving SOL showed a lower reduction in mean global QoL (-2.76 vs. -14.11; mean difference [MD], 11.34; 95% confidence interval [CI], 8.28 to 14.41), greater improvement in physical function (MD, 11.61; 95% CI, 8.57 to 14.65), role function (MD, 10.15; 95% CI, 5.75 to 14.54), and emotional function (MD, 4.71; 95% CI, 1.85 to 7.57), and greater improvements in lung cancer-related symptoms (e.g., fatigue, nausea/vomiting, and appetite loss) and performance status during the 6-month follow-up period (treatment main effect, p < 0.05). CONCLUSION SOL treatment for NSCLC patients receiving adjuvant chemotherapy can significantly improve QoL and performance status within 6 months after radical resection.

Acta radiologica (Stockholm, Sweden : 1987). 2023;(4):1311-1321
Abstract
BACKGROUND A non-invasive tool for tumor regression grade (TRG) evaluation is urgently needed for gastric cancer (GC) treated with neoadjuvant chemotherapy (NAC). PURPOSE To develop and validate a radiomics signature (RS) to evaluate TRG for locally advanced GC after NAC and assess its prognostic value. MATERIAL AND METHODS A total of 103 patients with GC treated with NAC were retrospectively recruited from April 2018 to December 2019 and were randomly allocated into a training cohort (n = 69) and a validation cohort (n = 34). Delineation was performed on both mixed and iodine-uptake images based on dual-energy computed tomography (DECT). A total of 4094 radiomics features were extracted from the pre-NAC, post-NAC, and delta feature sets. Spearman correlation and the least absolute shrinkage and selection operator were used for dimensionality reduction. Multivariable logistic regression was used for TRG evaluation and generated the optimal RS. Kaplan-Meier survival analysis with the log-rank test was implemented in an independent cohort of 40 patients to validate the prognostic value of the optimal RS. RESULTS Three, five, and six radiomics features were finally selected for the pre-NAC, post-NAC, and delta feature sets. The delta model demonstrated the best performance in assessing TRG in both the training and the validation cohorts (AUCs=0.91 and 0.76, respectively; P>0.1). The optimal RS from the delta model showed a significant capability to predict survival in the independent cohort (P<0.05). CONCLUSION Delta radiomics based on DECT images serves as a potential biomarker for TRG evaluation and shows prognostic value for patients with GC treated with NAC.

Abstract
PURPOSE The phase II/III study of donafenib was initiated when there was no available treatment indicated for Chinese patients with progressive radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC). Donafenib, an oral tyrosine kinase inhibitor (TKI), showed good efficacy and tolerability in the phase II study. We aimed to further evaluate the antitumor activity and safety of donafenib in Chinese patients with RAIR-DTC. PATIENTS AND METHODS This multicenter, double-blind, placebo-controlled, phase III study enrolled 191 patients with progressive RAIR-DTC and randomized in a ratio of 2:1 to donafenib (300 mg twice daily, n = 128) or matched placebo (n = 63). An open-label donafenib treatment period was allowed upon disease progression. The primary endpoint was progression-free survival (PFS) assessed by the independent review committee. The second endpoints include objective response rate (ORR), disease control rate (DCR), safety, etc. RESULTS Donafenib demonstrated prolonged median PFS over placebo [12.9 vs. 6.4 months; hazard ratio (HR), 0.39; 95% confidence interval (CI), 0.25-0.61; P < 0.0001] in Chinese patients with RAIR-DTC. Improved ORR (23.3% vs. 1.7%; P = 0.0002) and DCR (93.3% vs. 79.3%; P = 0.0044) were observed in the donafenib group over placebo. For donafenib, the most common grade ≥ 3 treatment-related adverse events (AE) included hypertension (13.3%) and hand-foot syndrome (12.5%), 42.2% underwent dose reduction or interruption, and 6.3% experienced discontinuation. CONCLUSIONS Donafenib was well-tolerated and demonstrated clinical benefit in terms of improved PFS, ORR, and DCR in patients with RAIR-DTC. The results suggest that donafenib could be a new treatment option for patients with RAIR-DTC.

Abstract
BACKGROUND Many lifestyle interventions have demonstrated efficacy up to one-year follow-up, yet maintaining improvements at longer-term follow-up is a well-recognized worldwide challenge, especially in underserved areas. The purpose of this study is to compare the 18-month efficacy of an Intensive LifeStyle Modification Program to usual care in reducing the risk for type 2 diabetes (T2D) among women with a history of gestational diabetes mellitus (GDM). METHODS We conducted a two-arm, cluster randomized controlled trial among women with a history of GDM in China. A total of 16 towns (clusters) in two distinct rural areas in south-central China were randomly selected (8 towns per area) and assigned (1:1) to the intervention (Intensive LifeStyle Modification Program) or control (usual care) group with stratification in the two rural areas. The strategies for maintaining intervention effects were used (including setting recursive goals and providing a supportive environment, etc.) under the guidance of social cognitive theory. The primary outcome was a change in T2D risk; secondary outcomes included glycemic, weight-related, behavioral, and psychological variables. All outcomes were collected at baseline, 6, and 18 months. All participants entered the intention-to-treat analysis. Data were analyzed via generalized estimation equation models (accounting for clusters) at the individual level, with subgroup analysis included in the model. RESULTS The sample included 320 women from 16 clusters (20 women per cluster). At 18 months, the intervention group demonstrated a significant improvement in T2D risk score, fasting blood glucose, body mass index (BMI), waist circumference, intention to eat low glycemic index food, perceived stress, quality of life in psychological and environmental domains, and social support over time (p < 0.05) based on the intention-to-treat analysis set. Subgroup analysis showed a significant interaction effect on T2D risk score in subgroups of different BMI, waist circumference, and blood glucose (p < 0.05). CONCLUSIONS Over 18 months, the Intensive LifeStyle Modification Program reduced T2D risk among rural women with a history of GDM in China. Women who were overweight, had high abdominal adiposity, or had blood glucose intolerance benefited more from this intervention. This program serves as a potential diabetes prevention model for women with a history of GDM in low-resource settings worldwide.

Abstract
BACKGROUND Intensive systolic blood pressure (SBP) control improved outcomes in the Strategy of Blood Pressure Intervention in the Elderly Hypertensive Patients (STEP) trial. Whether baseline serum lipid parameters influence the benefits of intensive SBP control is unclear. METHODS The STEP trial was a randomized controlled trial that compared the effects of intensive (SBP target of 110 to <130 mmHg) and standard (SBP target of 130 to <150 mmHg) SBP control in Chinese patients aged 60 to 80 years with hypertension. The primary outcome was a composite of cardiovascular disease events. A total of 8283 participants from the STEP study were included in this post hoc analysis to examine whether the effects of the SBP intervention differed by baseline low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) concentrations. RESULTS Regardless of the randomized SBP intervention, baseline LDL-C and non-HDL-C concentrations had a J-shaped association with the hazard of the primary outcome. However, the effects of the intensive SBP intervention on the primary outcome were not influenced by baseline LDL-C level ( P for interaction = 0.80) and non-HDL-C level ( P for interaction = 0.95). Adjusted subgroup analysis using tertiles in LDL-C1 (hazard ratio [HR], 0.77; 95% confidence interval [CI], 0.52-1.13; P = 0.18), LDL-C2 (HR, 0.81; 95% CI, 0.55-1.20; P = 0.29), and LDL-C3 (HR, 0.68; 95% CI, 0.47-0.98; P = 0.04) was provided, with an interaction P value of 0.49. Similar results were showed in non-HDL-C1 (HR, 0.87; 95% CI, 0.59-1.29; P = 0.49), non-HDL-C2 (HR, 0.70; 95% CI, 0.48-1.04; P = 0.08), and non-HDL-C3 (HR, 0.67; 95% CI, 0.47-0.95; P = 0.03), with an interaction P -value of 0.47. CONCLUSION High baseline serum LDL-C and non-HDL-C concentrations were associated with increased risk of primary cardiovascular disease outcome, but there was no evidence that the benefit of the intensive SBP control differed by baseline LDL-C and non-HDL-C concentrations.

Abstract
OBJECTIVE To determine whether silastic ring laparoscopic Roux-en-Y gastric bypass (SR-LRYGB) or laparoscopic sleeve gastrectomy (LSG) produces superior diabetes remission at 5 years. RESEARCH DESIGN AND METHODS In a single-center, double-blind trial, 114 adults with type 2 diabetes and BMI 35-65 kg/m2 were randomly assigned to SR-LRYGB or LSG (1:1; stratified by age-group, BMI group, ethnicity, diabetes duration, and insulin therapy) using a web-based service. Diabetes and other metabolic medications were adjusted according to a prespecified protocol. The primary outcome was diabetes remission assessed at 5 years, defined by HbA1c <6% (42 mmol/mol) without glucose-lowering medications. Secondary outcomes included changes in weight, cardiometabolic risk factors, quality of life, and adverse events. RESULTS Diabetes remission after SR-LRYGB versus LSG occurred in 25 (47%) of 53 vs. 18 (33%) of 55 patients (adjusted odds ratios 4.5 [95% CI 1.6, 15.5; P = 0.009] and 4.2 [1.3, 13.4; P = 0.015] in the intention-to-treat analysis). Percent body weight loss was greater after SR-LRYGB than after LSG (absolute difference 10.7%; 95% CI 7.3, 14.0; P < 0.001). Improvements in cardiometabolic risk factors were similar, but HDL cholesterol increased more after SR-LRYGB. Early and late complications were similar in both groups. General health and physical functioning improved after both types of surgery, with greater improvement in physical functioning after SR-LRYGB. People of Māori or Pacific ethnicity (26%) had lower incidence of diabetes remission than those of New Zealand European or other ethnicities (2 of 25 vs. 41 of 83; P < 0.001). CONCLUSIONS SR-LRYGB provided superior diabetes remission and weight loss compared with LSG at 5 years, with similar low risks of complications.

Abstract
PURPOSE To examine the effect of hydroxypropyl-guar nanoemulsion (HP-Guar nanoemulsion, Alcon Laboratories Ltd, Fort Worth, TX, USA) versus saline (0.9% sodium chloride; Pfizer Inc., Bentley WA Australia) on the comfort and tear film properties of people with dry eye disease both in the short-term (up to 2 h post-drop instillation) and longer-term (after 4 weeks of 4-times daily use), and to examine the effect on tear inflammatory markers after 4 weeks. METHODS This was a prospective, investigator-masked, randomised, cross-over dispensing study. Twenty participants with dry eye disease (5 males: 15 females) with average age 46.9 ± 14.4 (range 26 to 70) years were randomized to either HP-Guar nanoemulsion, or saline eye drops. Ocular symptoms, lipid layer thickness, tear evaporation, tear osmolarity and non-invasive break-up time were measured pre-drop instillation, 1 h and 2 h post-eye drop instillation, and after 4-weeks of 4-times daily drop use. Tear inflammatory mediators were measured pre-drop instillation and after 4-weeks. After 4-weeks, patients had a 4-week washout period and then crossed over to the alternate drop. RESULTS With HP-Guar nanoemulsion, participants reported less grittiness/burning/stinging 1 h post eye drop instillation compared to baseline (79.5 ± 23.3 vs. 66.8 ± 27.7, p = 0.02); less dryness 1 h and 2 h post eye drop instillation compared to baseline (77.8 ± 23.0 and 76.2 ± 23.7 vs. 61.0 ± 27.1 respectively, p < 0.01 for both); and greater overall satisfaction 1 h post drop instillation and after 4 weeks of daily use compared to baseline (80.4 ± 21.6 and 83.4 ± 16.6 vs. 68.6 ± 26.0 respectively, p ≤ 0.011 for both). With saline, participants reported less dryness after 4 weeks of daily use compared to baseline (74.2 ± 23.8 vs. 60.2 ± 24.0, p < 0.01). For HP-Guar nanoemulsion, average lipid layer thickness was significantly thicker 2 h post drop-instillation (79.5 ± 21.7 nm) compared to baseline (63.7 ± 18.9 nm) and the 4-week assessment (62.4 ± 23.1 nm, p < 0.01 for both). For saline, average lipid layer thickness was significantly thicker at 1 h and 2 h post eye drop instillation (76.0 ± 23.8 nm and 80.4 ± 24.8 nm) compared to baseline (61.0 ± 15.6 nm, p < 0.01 for both). There was no difference in inflammatory mediators or other tear variables between drops or visits. CONCLUSION HP-Guar nanoemulsion was more effective for improving a range of subjective dry eye symptoms both in the short and long-term compared to saline. Both HP-Guar nanoemulsion and saline transiently increased lipid layer thickness.

Contrast media & molecular imaging. 2022;:1035619
Abstract
This study investigates the value of magnetic resonance imaging (MRI) based on a deep learning algorithm in the diagnosis of diabetic macular edema (DME) patients. A total of 96 patients with DME were randomly divided into the experimental group (N = 48) and the control group (N = 48). A deep learning 3D convolutional neural network (3D-CNN) algorithm for MRI images of patients with DME was designed. The application value of this algorithm was comprehensively evaluated by MRI image segmentation Dice value, sensitivity, specificity, and other indicators and diagnostic accuracy. The results showed that the quality of MRI images processed by the 3D-CNN algorithm based on deep learning was significantly improved, and the Dice value, sensitivity, and specificity index data were significantly better than those of the traditional CNN algorithm (P < 0.05). In addition, the diagnostic accuracy of MRI images processed by this algorithm was 93.78 ± 5.32%, which was significantly better than the diagnostic accuracy of 64.25 ± 10.24% of traditional MRI images in the control group (P < 0.05). In summary, the 3D-CNN algorithm based on deep learning can significantly improve the accuracy and sensitivity of MRI image recognition and segmentation in patients with DME, can significantly improve the diagnostic accuracy of MRI in patients with DME, and has a good clinical application value.

Abstract
OBJECTIVES Muscle cramps occur in 33% to 78% of patients with dialysis. The etiology of muscle cramps is poorly understood, and no clear evidence-based prevention or treatment strategies exist. Improved interventions are urgently needed. The aim of this study was to investigate the effect of vitamin K2 in reducing the frequency and severity of muscle cramps in hemodialysis (HD) patients. METHODS This multicenter, randomized, placebo-controlled, crossover clinical trial was conducted from June 2019 to May 2020. Each participant received vitamin K2 (360 µg/d) or placebo for two 4-wk phases, and then crossed to the alternative arm for two 4-wk phases after a 2-wk washout. The primary endpoint was the frequency of muscle cramps during HD. The secondary endpoints were severity and duration of muscle cramps during HD. RESULTS A total of 523 patients with maintenance HD were screened for muscle cramps, including 41 patients with muscle cramps refractory to conventional interventions, were enrolled. Nineteen patients in the vitamin K2-initial group and 20 in the placebo-initial group completed the protocol, and were included in the final analysis. Vitamin K2 reduced the frequency, duration, and severity of muscle cramps in HD patients (all P < 0.05). The frequency, duration, and severity of muscle cramps in HD patients increased again after crossing over to the placebo. There were no serious adverse events. One patient experienced gastrointestinal discomfort when taking vitamin K2. CONCLUSIONS This pilot trial demonstrated that vitamin K2 supplementation could decrease the frequency, duration, and severity of muscle cramps in HD patients.

Abstract
AIM: The aim was to assess two macronutrient interventions in a 2 × 2 factorial dietary design to determine their effects on oral health. MATERIALS AND METHODS Participants (65-75 years old) with a body mass index between 20 and 35 kg/m2 of a larger randomized control trial who consented to an oral health assessment were recruited. They had ad libitum access to one of four experimental diets (omnivorous higher fat or higher carbohydrate, semi-vegetarian higher fat or higher carbohydrate) for 4 weeks. The periodontal examination included periodontal probing depth (PPD), clinical attachment level (CAL), and bleeding on probing. Oral plaque and gingival crevicular fluid (GCF) were collected before and after the intervention. RESULTS Between baseline and follow up, the number of sites with a CAL <5 mm (mean difference [MD] -5.11 ± 9.68, p = .039) increased and the GCF amount (MD -23.42 ± 39.42 Periotron Units [PU], p = .050) decreased for the semi-vegetarian high-fat diet. For the mean proportion of sites with PPD reduction of >1 mm and CAL gain of >1 mm, significant differences were calculated between the diets investigated. The clinical parameters were not associated with changes in the oral microbiota. CONCLUSIONS The results of this study provided evidence that a semi-vegetarian high-fat diet provides benefits to clinical parameters of periodontal health. This study is registered in ClinicalTrials.gov (ACTRN12616001606471).
