Abstract
PURPOSE Information is scarce on the five-year effect of laparoscopic Roux-en-Y Gastric Bypass (LRYGB) on body composition for Type 2 diabetes mellitus (T2DM) patients with a low BMI. This study aimed to evaluate the five-year changes in body composition in a Chinese T2DM cohort with a BMI < 32.5 kg/m2 after LRYGB. METHODS Twenty-seven T2DM patients were assessed preoperatively (baseline) and 3 months, 6 months, 1 year, 3 years, and 5 years after LRYGB with dual-energy X-ray absorptiometry (DXA). RESULTS DXA assessments were completed in 100%, 85%, 85%, 85%, 48%, and 37% at baseline and 3 months, 6 months, 1 year, 3 years, and 5 years, respectively. For the whole body, fat-free mass and muscle mass decreased from 6 months to 5 years after LRYGB (P < 0.05), while bone mineral content decreased at 5 years after LRYGB (P < 0.05). Fat mass of different regions decreased from 3 months to 1 year (P < 0.05), and a similar magnitude of variation was observed in body fat mass percentage. A fat redistribution characterized by the regional fat proportion of trunk and android decreasing and the regional fat proportion of limbs gaining (P < 0.05) occurred at 5 years after LRYGB. CONCLUSION For low BMI patients with T2DM, LRYGB led to a short-term reduction in FM and a lasting reduction in FFM. A metabolically healthy fat redistribution occurring 5 years after LRYGB might be a promising mechanism to explain the lasting benefits of LRYGB for T2DM patients with a low BMI.

Abstract
OBJECTIVE This study aimed to evaluate the difference of two various robotic technology applied in R- Total mesorectal excision (TME). METHODS From May 2017 to December 2018, consecutive patients with rectal cancer who underwent da Vinci R-TME or Micro Hand S R-TME were enrolled. The comparative study was conducted on Short-term Operative, Oncological, and Functional Outcomes between two type of R-TME. RESULTS 47 patients underwent da Vinci R-TME, and 43 patients underwent Micro Hand S R-TME. No difference occured between two groups in TME completeness, CRM, DRM, CRM involvement and DRM involvement, operative time, blood loss, protective ileostomy, conversion rate, number of retrieved lymph nodes, Comprehensive Complication Index (CCI), International Prostate Symptom Score (IPSS) or Wexner scores. However, the setup time in the Micro Hand S group was longer. CONCLUSIONS In the present study, both da Vinci R-TME and Micro Hand S R-TME achieve excellent TME quality with acceptable morbidity and postoperative function.

Abstract
OBJECTIVE To investigate the injury types of atrial myocytes induced by heat exposure and the effect of amiodarone on heat-induced injuries in atrial myocytes. OBJECTIVE The optimal temperature for heat exposure and optimal concentration of amiodarone were determined by measuring the cell viability exposed to different temperatures and different concentrations of amiodarone. Heat exposure of HL1 atrial myocytes was conducted using a water bath, and the effect of amiodarone on cell viability was assessed with MTS method; cell apoptosis was detected using flow cytometry, and the levels of IL-1β, IL-6, TNF-α, SOD and MDA were detected with enzyme-linked immunosorbent assay (ELISA). OBJECTIVE Compared with the blank control cells, the cells exposed to a temperature of 52 ℃ showed a significantly decreased survival rate and a lowered SOD activity (P < 0.001) with increased IL-1β and MDA levels (P < 0.01) and markedly increased apoptosis rate and IL-6 level (P < 0.001). Compared with the heat exposure group, amiodarone resulted in significantly decreased survival rate of the atrial myocytes (P < 0.01), obviously decreased SOD activity (P < 0.05), and increased cell apoptosis rate (P < 0.05) and IL-1β, IL-6, MDA and TNF-α levels (P < 0.01 or 0.001). OBJECTIVE Heat exposure induces apoptosis, inflammation and oxidative stress in mouse HL1 atrial myocytes, and amiodarone can enhance the effects of heat exposure to aggravate the cell injuries.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is an effective treatment for morbidly obese patients to improve type 2 diabetes mellitus (T2DM). Recently, T2DM patients with a lower body mass index (BMI) have been receiving more attention, and these patients could benefit from RYGB. METHODS Fifty-two patients with T2DM underwent RYGB between October 2008 and December 2012 in our hospital. Weight, BMI, oral glucose tolerance test (OGTT), insulin release test (IRT), C-peptide release test (CRT), glycosylated hemoglobin (HbA1c), and lipid metabolic parameters were measured at baseline and at 3 and 6 months and 1, 2, 3, 4, 5, and 6 years after surgery. RESULTS The mean age of the 52 patients was 46.8 ± 9.5 years, and 57.7% were male. The mean duration of T2DM was 6.5 ± 4.6 years. Compared with the baseline values, weight and BMI were significantly decreased at several time points after surgery. HbA1c decreased from 8.2 ± 1.7% at baseline to 6.5 ± 1.4% at 3 months, 6.5 ± 1.4% at 6 months, 7.2 ± 1.3% at 4 years, and 7.5 ± 1.2% at 6 years. OGTT, OGTT-IRT, and OGTT-CRT improved after surgery. There was a decrease in triglycerides (TGs), total cholesterol (TC), and low-density lipoprotein (LDL) and an increase in high-density lipoprotein (HDL). At 6 years after surgery, 16.7% of patients achieved complete remission of T2DM, and 66.7% achieved improvement in T2DM. CONCLUSION RYGB may be a safe and effective treatment for T2DM patients with a BMI < 32.5 kg/m2 in China. However, a long-term study without loss to follow-up is necessary for better evaluation.

Abstract
Abstract
Introduction
Family caregivers of older patients with newly diagnosed lung cancer become responsible for patients’ care, usually without preparation or training in provision of care. Their efforts of care generate caregiving burden, which could deteriorate their quality of life and affect the prognosis of patients. The aims of this study were to examine associations between caregiver burden and quality of life, coping, social support for family caregivers, and to investigate whether coping and social support mediate associations between family caregiver burden and their quality of life.
Methods
A cross-sectional study was performed at two thoracic surgery wards in one tertiary hospital in Changsha, China from November 2019 to May 2020. This study involved 224 family caregivers of patients aged over 50 years and newly diagnosed with lung cancer. Caregivers-reported outcomes were measured by Zarit caregiver burden interview, simplified coping style questionnaire, social support rating scale, and quality of life family version. Structural equation modeling (SEM) was used to test the hypothesized mediation model.
Results
SEM indicated a good fit for the mediation model, which explained 49.7% of the variance of quality of life. Higher level of caregivers’ burden was negatively associated with quality of life (r = 0.183, P = 0.042). Coping partially mediated the effect of caregiver burden on quality of life (indirect effect −0.389, P = 0.000). Social support did not mediate the relationship between caregiver burden and quality of life (indirect effect −0.023, P = 0.087).
Conclusions
Caregivers’ burden of patients with newly diagnosed lung cancer is correlated to quality of life which is partially mediated by coping. Early intervention providing caregivers with positive coping strategies may improve their quality of life.

Abstract
Abstract
Introduction
Medication self-management support has been recognised as an essential element in primary health care to promote medication adherence and health outcomes for older people with chronic conditions. A patient-centred intervention empowering patients and supporting medication self-management activities could benefit older people. This pilot study tested a newly developed medication self-management intervention for improving medication adherence among older people with multimorbidity.
Method
This was a two-arm randomised controlled trial. Older people with multimorbidity were recruited from a community healthcare centre in Changsha, China. Participants were randomly allocated to either a control group receiving usual care (n = 14), or to an intervention group receiving three face-to-face medication self-management sessions and two follow-up phone calls over six weeks, targeting behavioural determinants of adherence from the Information-Motivation-Behavioural skills model (n = 14). Feasibility was assessed through recruitment and retention rates, outcome measures collection, and intervention implementation. Follow-up data were measured at six weeks after baseline using patient-reported outcomes including medication adherence, medication self-management capabilities, treatment experiences, and quality of life. Preliminary effectiveness of the intervention was explored using generalised estimating equations.
Results
Of the 72 approached participants, 28 (38.89%) were eligible for study participation. In the intervention group, 13 participants (92.86%) completed follow-up and 10 (71.42%) completed all intervention sessions. Ten participants (71.42%) in the control group completed follow-up. The intervention was found to be acceptable by participants and the intervention nurse. Comparing with the control group, participants in the intervention group showed significant improvements in medication adherence (β = 0.26, 95%CI 0.12, 0.40, P < 0.001), medication knowledge (β = 4.43, 95%CI 1.11, 7.75, P = 0.009), and perceived necessity of medications (β = −2.84, 95%CI -5.67, −0.01, P = 0.049) at follow-up.
Conclusions
The nurse-led medication self-management intervention is feasible and acceptable among older people with multimorbidity. Preliminary results showed that the intervention may improve patients’ medication knowledge and beliefs and thus lead to improved adherence.

Abstract
Abstract
Introduction
Frailty is associated with an increased risk of falling and fracture, but not routinely assessed in fracture clinic. Early identification and management of frailty among older people with arm fragility fracture could help avoid further falls and fractures, especially of the hip. We evaluated the feasibility of assessing frailty in a busy fracture clinic.
Methods
People aged 65+ years with an arm fracture in one acute trust were recruited. Frailty was assessed in fracture clinics using six tools: Fried Frailty Phenotype (FFP), FRAIL scale, PRISMA-7, electronic Frailty Index (e-FI), Clinical Frailty Score (CFS), and Study of Osteoporotic Fracture (SOF). The sensitivity and specificity of each tool was compared against FFP as a reference. Participants identified as frail by 2+ tools were referred for Comprehensive Geriatric Assessment (CGA).
Results
100 patients (mean age 75 years±7.2; 20 men) were recruited. Frailty prevalence was 9% (FRAIL scale), 13% (SOF), 14% (CFS > 6), 15% (FFP; e-FI > 0.25), and 25% (PRISMA-7). Men were more likely to be frail than women. Data were complete for all assessments and completion time ranged from one minute (PRISMA-7; CFS) to six minutes for the FFP which required most equipment. Comparing with FFP, the most accurate instrument for stratifying frail from non-frail was the PRISMA-7 (sensitivity = 93%, specificity = 87%) while the remaining tools had good specificity (range 93%–100%) but average sensitivity (range 40%–60%). Twenty patients were eligible for CGA. Five had recently had CGA and 11/15 referred were assessed. CGA led to 3–6 interventions per participant including medication changes, life-style advice, investigations, and onward referrals.
Conclusion
It was feasible to assess frailty in fracture clinic and to identify patients who benefitted from CGA. Frailty prevalence was 9%—25% depending on the tool used and was higher among men. PRISMA-7 could be a practical tool for routine use in fracture clinics.

Abstract
Abstract
Introduction
Osteoporosis and sarcopenia often co-exist (osteo-sarcopenia) and both are associated with increased risk of falls and fractures. Early identification and treatment of sarcopenia among older people with fragility arm fractures could prevent further fractures. This study evaluated the feasibility of assessing sarcopenia in a fracture clinic.
Methods
People aged 65+ years with arm fracture attending fracture clinics in one acute trust were recruited. Sarcopenia was assessed using gait speed, grip strength with unfractured arm (hand dynamometer using appropriate cut off adjusted for age and gender), skeletal muscle mass index SMI (Bioimpedance BIA), SARC-F questionnaire, the European Working Group on Sarcopenia in Older People (EWGSOP) I and II criteria. The sensitivity and specificity of each measure was calculated against the EWGSOP II criteria as the standard reference.
Results
100 patients (Mean age 75 years±7.2; 80 female) were recruited. Sarcopenia was identified among 4% (EWGSOP I), 5% (SMI), 13% (EWGSOP II), 16% (gait speed test), 18% (SARC-F) and 39% (grip strength) and was more prevalent among men. SARC-F had the best sensitivity and specificity (100% and 96% respectively) when compared to the EWGSOP II criteria. Sensitivity and specificity for the remaining measures were respectively (100%, 71%) for grip strength, (75%, 94%) for gait speed, (25%, 97%) with SMI and (25%, 99%) for EWGSOP I. Time needed to complete the assessments was 1–2 minutes for gait speed, grip strength and SARC-F; five minutes for BIA test, and nine minutes when EWGSOP I and II criteria were applied. Data were complete for grip strength and SARC-F. Missing data was reported among 2% for gait speed, 8% for BIA test, 8% for EWGSOP II and 10% for EWGSOP I.
Conclusion
It was feasible to assess sarcopenia in fracture clinics and SARC-F was a quick, simple and sensitive tool suitable for routine use.

Abstract
The replacement of a damaged temporomandibular joint (TMJ) disc remains a long-standing challenge in clinical settings. No study has reported a material with comprehensively excellent properties similar to a natural TMJ disc. In this work, we designed a novel artificial TMJ disc using polyvinyl alcohol (PVA) hydrogel crosslinked by cyclic freeze-thaw and reinforced by 3D-printed polycaprolactone (PCL) implants. The mechanical properties and surface morphologies of the artificial TMJ disc and the natural goat TMJ disc were tested and compared via compression, tensile, cyclic compression/tensile, creep, friction, scanning electron microscopy, and atomic force microscopy. The fibroblasts and chondrocytes were cultured on the artificial TMJ disc for 1, 3, and 5 d for cytotoxicity testing. Importantly, the artificial discs were placed into the TMJs of goats in an innovative way to induce disc defect repair for 12 wk. The PVA + PCL artificial disc demonstrated mechanical strength similar to that of natural disc, as well as 1) better fatigue resistance, viscoelasticity, and hydrophilicity; 2) less creep; and 3) low friction, cytotoxicity, and cell adhesion. By repairing the defects of the TMJ disc in goats, the artificial disc demonstrated the ability to maintain joint stability and protect condylar cartilage and bone from damage. These promising results indicate the feasibility of using a PVA + PCL artificial TMJ disc in a clinical context.

Abstract
Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been proved to be a safe and effective treatment for Type 2 diabetes mellitus (T2DM) patients with body mass index (BMI) >27.5 kg/m2 in China. The incidence of gastrointestinal stromal tumor (GIST) is very low, whereas the relevant studies on GIST and LRYGB are few. This is the first report of GIST associated with LRYGB in low BMI Chinese patient with T2DM.A male patient with GIST and T2DM, whose body weight and height were 67 kg and 175 cm, respectively,and the calculated BMI was 21.9 kg/m2. He was diagnosed by gastroscopy and enhanced CT scan. We used LRYGB to treat GIST and T2DM at the same time. After the operation, the GIST was removed successfully. Both the blood glucose levels and glycosylated hemoglobin were normal at 4 months and 1 year later. The patient received follow-up gastroscopy and abdominal CT scan and did not find out local recurrence and metastasis. LRYGB may be the best choice in treating GIST in T2DM with low BMI.

Abstract
People over age 50 living with HIV experience frailty including functional declines and illnesses usually attributed to aging, more frequently and ten years earlier than people without HIV. As the number of people living with HIV over age 50 is expected to triple by the year 2040, those experiencing early frailty will continue to grow. This review synthesizes the known correlates and contributors to musculoskeletal frailty in people living with HIV. A conceptual model of musculoskeletal frailty in HIV that outlines chronic inflammation, altered energy metabolism, immune activation, and endocrine alterations as mechanisms associated with frailty development is presented. Additionally, the potential ability of aerobic exercise to modify the risk of frailty is highlighted as an important intervention.

OBJECTIVES To examine the diagnostic performance of the Tilburg Frailty Indicator (TFI), 11-factor modified frailty index (mFI-11), and 5-factor modified frailty index (mFI-5) for frailty defined by Frailty Phenotype (FP), as well as to compare the predictive ability of TFI, mFI-11, and mFI-5 for adverse outcomes in hospital among elderly patients undergoing gastric cancer surgery. DESIGN A prospective cohort study. SETTING Hospitalization setting, Nanjing, China. PARTICIPANTS We recruited 259 elderly patients undergoing gastric cancer surgery from a tertiary hospital. MEASUREMENTS Frailty was assessed by the FP, TFI, mFI-11, and mFI-5 before surgery, respectively. The receiver operating characteristic (ROC) curves were plotted to compared the diagnostic performance of TFI, mFI-11, and mFI-5 using FP as the reference. ROC curves were used to examine the performance of TFI, mFI-11, and mFI-5 in predicting adverse outcomes. The area under the curve (AUC)>0.70 was regarded as an indicator of good performance. RESULTS The prevalence of frailty ranged from 8.5% (mFI-11) to 45.9% (TFI). The AUCs of TFI (AUC: 0.764, p<0.001) was significantly greater than that of mFI-11 (AUC: 0.600, p=0.033) and mFI-5 (AUC: 0.600, p=0.0311) in the detection of frailty defined by FP, with quite different sensitivity and specificity at their original cutoffs. TFI and mFI-11 both had statistically significant but similarly inadequate predictive accuracy for adverse outcomes in hospital, including total complications (AUCs: 0.618; 0.621), PLOS (AUCs: 0.593; 0.639), increased hospital costs (AUCs: 0.594; 0.624), and hypoproteinemia (AUCs: 0.573; 0.600). For the mFI-5, only the predictive ability for hypoproteinemia was statistically significant, with poor accuracy (AUC: 0.592, p<0.0055). CONCLUSION The TFI performed slightly better than mFI-11 and mFI-5 in our study. Moreover, future studies are needed to further determine an optimal frailty instrument with great diagnostic and predictive accuracy.

Abstract
OBJECTIVE The aim of this study was to retrospectively analyze clinical characteristics and laboratory results of the novel coronavirus pneumonia (COVID-19) patients so as to identify factors related to disease progression. PATIENTS AND METHODS Sixty-one patients with COVID-19 were divided into two groups: an improvement/stabilization group (n = 53) and a progression group (n = 8). Clinical data were collected to analyze and compare the differences between the two groups. RESULTS Of the sixty-one patients, thirty-one were male (50.8%), and thirty were female (49.2%), with a median age of 53 years. On admission, significant differences were observed between the two groups with respect to the levels of Creatine Kinase (CK), lymphocytes, D-dimer and creatinine, and prothrombin time (PT). Univariate logistic regression analysis showed that Platelet-to-lymphocyte ratio (PLR), lymphocytes, Mean platelet volume to lymphocyte ratio (MPVLR), CK, White Blood count to mean platelet volume ratio (WMR), Lymphocyte-to-monocyte ratio (LMR), and serum creatinine were important factors for disease progression. Multivariate logistic regression analysis showed that PLR was an independent factor for disease progression in COVID-19 patients. The receiver operating characteristic (ROC) curve revealed that the best predictor of disease progression was CK. Dynamic changes in the laboratory indicators of patients were tracked, and significant differences were found in the variation trends of white blood cell count, neutrophil count, and WMR, which gradually increased in the progression group, but gradually decreased in the improvement/stabilization group. CONCLUSIONS Risk factors for disease progression included PLR, lymphocytes, MPVLR, CK, WMR, LMR, and creatinine, among which, PLR is an independent risk factor for disease progression in COVID-19 patients.

Abstract
Abstract
Background
There have been few practical and precise tools to predict response after cardiac resynchronisation therapy (CRT).
Purpose
We intend to develop predictive models using machine learning (ML) approaches and easily available features prior to implantation.
Methods
The baseline features of 596 patients receiving CRT were retrospectively collected. Nine predictive models were established, including logistic regression (LR), Elastic Net (EN), lasso regression, ridge regression (Ridge), neural network, support vector machine (SVM), random forest, XGBoost and k-nearest neighbor. Sensitivity, specificity, precision, accuracy, F1, area under receiver operating characteristic curve (AU-ROC) and average precision of each model were evaluated, and AU-ROC was compared between each pair of ML models and further between ML models and the latest guidelines.
Results
Sensitivity was highest with SVM by 0.69, and specificity was highest with LR by 0.81. The models EN and Ridge showed the highest overall predictive power with an average AU-ROC of 0.77. Specifically, the Ridge model provided significant higher AU-ROC than any other model (all P<0.05). All ML models showed significant higher AU-ROC than those derived from the latest guidelines (all P<0.05). Additionally, the effect size analysis identified LBBB, LVESD, and history of PCI as the most crucial predictive features.
Conclusion
ML algorithms produced efficient predictive models for evaluation of response after CRT with features prior to implantation. Tools developed accordingly might improve selection of CRT candidates and reduce rate of non-response in the future.
