Abstract
BACKGROUND: Older patients often experience a decline in physical function and cognitive status after hospitalization. Although interventions involving physical exercise are effective in improving functional performance, participation in physical exercise interventions among older individuals is low. We aimed to identify factors that contribute to exercise refusal among post-hospitalized older patients.METHODS: A cross-sectional study of recruitment data from a randomized controlled trial was conducted involving 495 hospitalized people ≥70 years old. Sociodemographic and clinical data were obtained from the Basque Public Health System database. We determined physical function with the Short Physical Performance Battery (SPPB), nutritional status with the Mini-Nutritional Assessment, frailty according to the Fried phenotype criteria, and cognitive function with the Short Portable Mental Status Questionnaire (SPMSQ). Student’s t, Mann-Whitney U, or chi-squared tests were applied for bivariate analysis. Parameters significantly associated with participation were introduced in a logistic multivariate regression model.RESULTS: Among the analyzed patients, 88.8% declined participation in the physical exercise program. Multivariate regression revealed that older age (OR: 1.13; 95% CI: 1.07 - 1.19), poor nutritional status (OR: 0.81; 95% CI: 0.69 - 0.95), and reduced home accessibility (OR: 0.27; 95% CI: 0.08 - 0.94) were predictors of participation refusal. Moreover, patients who declined participation had worse performance on the SPPB (P < 0.05) and its tests of balance, leg strength, and walking speed (P < 0.05). No differences were found between groups in other variables. CONCLUSIONS: This study confirms low participation of older adults in a post-hospitalization physical exercise program. Non-participation was associated with increased age, poor nutritional status, and reduced home accessibility. Our findings support the need for intervention design that accounts for these factors to increase older patient participation in beneficial exercise programs.TRIAL REGISTRATION: ACTRN12619000093189 (retrospectively registered): Registered January 22, 2019.

Abstract
Background: Eswatini continues to have the highest prevalence of HIV in the world, and one of the highest HIV incidences among adult populations (aged 15-49). This analysis reports on both key elements of study design/protocol and baseline results from an impact evaluation of an intervention incentivizing (i) initiation, enrolment, attendance or completion of some form of education, and (ii) lower risk sexual behaviour.Methods: The impact evaluation employs a two by two factorial design in which participants are enrolled in either the incentive for education arm (‘education treatment arm’ providing a conditional cash incentive) or the control arm (‘education control arm’). In each of these arms, 50% of participants were randomized to also be eligible for selection – three times a year – to participate in a conditional raffle conditional on testing negative for curable STIs (syphilis and Trichomonas vaginalis ).Results: Baseline recruitment and screening occurred in 2016 when a total of 6,055 individuals were screened of which 4,863 participated in the baseline survey, and 4,819 individuals were randomized into one of the study arms. The baseline prevalence of HIV, Trichomonas vaginalis , and syphilis among adolescent girls and young women 8.20% (397/4,840), 3.31% (150/4,533) and 0.17% (8/4,830) respectively.Conclusions: An educational cash incentive and raffle incentive impact evaluation that addresses adolescent girls and young women who are in-education and out-of-education has the potential to reduce HIV risk in adolescent girls and young women in Eswatini.Name of the registry: Pan African Clinical Trials RegistryTrial registration number: PACTR201811609257043Date of registration: May 11, 2018 ‘Retrospectively registered’URL of trial registry record: https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=4685
Development and validation of oral chemotherapy self-management scale&nbsp;
Authors: Peng Qi , Wu Wanying 
Published: September 2020

Abstract
Background: With the increase of oral chemotherapy drugs, patients receiving cancer treatment prefer oral chemotherapy versus intravenous, given equal efficacy and toxicity. However, they need to take an active part in their care, which is vital with home-based oral therapy, therefore the self-management is important for patients with oral chemotherapy. Unfortunately, the development of self-management assessment tools for oral chemotherapy still lags behind. Methods: The OCSMS item pool was formulated based on literature review and semi-structured interviews, An initial scale containing 5 dimensions and 38 items was constructed through research seminar, Delphi survey and pilot testing. To assess the validity and reliability, We recruited 261 patients from cancer hospital in China. Results: A 36-item scale was developed with five dimensions identified through factor analysis: daily life management, symptom management, medication management, emotional cognitive management and social support. Cronbach’s coefficient Alpha, split-half coefficient, test-retest reliability and S-CVI/UA scores were 0.929, 0.773, 0.966 and 0.833, respectively, indicating that OCSMS has good reliability and validity.Conclusions: The OCSMS is a valid, reliable measurement method of the self-management ability of patients with oral chemotherapy. The OCSMS shows potential as a tool to ensure the safety of patients with cancer. The OCSMS may help evaluate the effectiveness of interventions to improve the self-management ability of patients.

Published: September 2020

Abstract
Background: Growth differentiation factor 15(GDF-15) concentration is apparently associated with cardiovascular disease, but whether there is a causal relationship has not been testified. Methods: We utilized Mendelian randomization to assess the function of GDF-15 in incidence of cardiovascular disease. The single-nucleotide polymorphism- GDF-15 association evaluations came from meta-analysis of genome-wide association study (GWAS). Besides inverse-variance weighted, MR-Egger test and weighted median method were applied to examine sensitivity. Results: Based on the instruments, GDF-15 level linked to the increasing risk of cardioembolic stroke (OR 1.09 per SD increase, 95% CI 1.01, 1.19) , atrial fibrillation (OR 1.03 per SD increase, 95% CI 1.0, 1.06), coronary artery disease (OR 0.94 per SD increase, 95% CI 0.89, 0.99) and myocardial infarction (OR 0.94 per SD increase, 95% CI 0.90, 0.98). However, the significant causal relationship between GDF-15 and the other cardiovascular diseases was not found in our study. Conclusions: The result suggested that GDF-15 was causally associated with the risk of cardioembolic stroke,atrial fibrillation, coronary artery disease and myocardial infarction, providing us conceivable strategies to alleviate the burden of cardiovascular disease.

Abstract
Linqing brick is quite popular in Chinese history. Currently, identifying the origin of Linqing brick is an important issue to be studied in the field of archeology and architectural history in China. Hand-Held X-ray fluorescence (HH-XRF) spectrometry enables the in-situ determination of the main elements in Linqing brick in a rapid non-destructive manner. HH-XRF is important in identifying the origin of Linqing brick. However, HH-XRF could be influenced by certain factors and may be capable of measuring only the element contents of the surface for the bricks in situ. The present study aimed to verify the reliability of HH-XRF and to systematically evaluate the different factors influencing measurement precision and accuracy so that scientific advice could be provided regarding the usage of HH-XRF for this application. Four experiments were performed to determine the influencing factors and assess the reliability through cross-validation using inductively coupled plasma optical emission spectrometry (ICP-OES). Finally, the influence of the different studied factors was studied, and the reliability of HH-XRF was ensured. The facts to consider about the measurement time, cross validation, criteria to select points, treat surface and getting final data and how to avoid the effect of rain, while using this method, are provided.

Abstract
Background:Before studying gene expression of different organisms, it is important to determine the best reference gene. At present, the most accurate method of detecting gene expression is quantitative real-time PCR (RT-qPCR). With this method, reference genes that are stable in different biological systems and under different conditions can be obtained. Toona ciliata Roem ( T. ciliata ). is a valuable and fast-growing timber specie. In this study, 20 reference genes were identified using RT-qPCR, as a primary prerequisite for future gene expression analysis. Four different methods, geNorm, NormFinder, BestKeeper, and RankAggreg were used to evaluate the expression stability of the 20 candidate reference genes in various tissues under different conditions.Results:The experimental results showed that TUB-α was the most stably expressed reference gene across all samples and UBC17 was the most stable in leaves and young stems under Hypsipyla robusta ( H. robusta ) and methyl jasmonate (MeJA) treatments. In addition, PP2C59 and UBC5B were the best-performing genes in leaves under H. robusta treatment, while HIS1 and ACT7 were the best reference genes in young stems. The two best reference genes were 60S-18 and TUB-α after treatment at 4 °C. The expression of HIS6 and MUB1 was the most stable under PEG6000 treatment. The accuracy of the selected reference genes was verified using the transcription factor MYB3 ( TcMYB3) gene.Conclusions:This is the first report to verify the best reference genes for normalizing gene expression in T. ciliata under different conditions, which will facilitate future elucidation of gene regulations in this species.

Abstract
Background Bacterial infections are a significant cause of sickness and death in sub-Saharan Africa. This study aimed at establishing the prevalence, distribution and antimicrobial susceptibility pattern of major bacterial isolates from patients accessing medical care at a tertiary hospital in Malawi. Methods We retrospectively reviewed bacteria culture and antimicrobial susceptibility records for 4,617 patients from 2002 to 2014 at Mzuzu Central Hospital (MCH). No inclusion and exclusion criteria were followed. Data was analysed using excel (Microsoft office, USA) and GraphPad prism 7 software programs. Results The most prevalent isolates were S. aureus (34.7%, n = 783), Klebsiella species (17.4%, n = 393) and Proteus species (11.4%, n = 256). Most microorganisms were isolated from adults (88.3%, n = 3889) and pus was the main source (69.3%, n = 1224). S. pneumoniae was predominantly isolated from cerebrospinal fluid (60.3%, n = 44) largely collected from children (88.2%, n = 64). Overall, most bacteria exhibited high resistance to all regularly used antimicrobials excluding ciprofloxacin. Conclusions Our report demonstrates an increase in bacterial infection burden in sites other than blood stream and subsequent increase in prevalence of antimicrobial resistance for all major isolates. Creating an epidemiological survey unit at MCH will be essential to help inform better treatment and management options for patients with bacterial infections.

Abstract
BackgroundMetabolic reprogramming is being recognized as a fundamental hallmark of cancer, and efforts to identify drugs that can target cancer metabolism are underway. In this study, we used human breast cancer (BC) cell lines and established their invading phenotype (INV) collected from transwell inserts to compare metabolome differences and evaluate prognostic significance of the metabolome in aggressive BC invasiveness. MethodsThe invasiveness of seven human BC cell lines were compared using the transwell invasion assay. Among these, INV was collected from SUM149, which exhibited the highest invasiveness. Levels of metabolites in INV were compared with those of whole cultured SUM149 cells (WCC) using CE-TOFMS. The impact of glycolysis in INV was determined by glucose uptake assay using fluorescent derivative of glucose (2-NBDG), and significance of glycolysis, or tricarboxylic acid cycle (TCA) and electron transport chain (ETC) in the invasive process were further determined in aggressive BC cell lines, SUM149, MDA-MB-231, HCC1937, using invasion assays in the presence or absence of inhibitors of glycolysis, TCA cycle or ETC. ResultsSUM149 INV sub-population exhibited a persistent hyperinvasive phenotype. INV were hyper-glycolytic with increased glucose (2-NBDG) uptake; diminished glucose-6-phosphate (G6P) levels but elevated pyruvate and lactate, along with higher expression of phosphorylated-pyruvate dehydrogenase (pPDH) compared to WCC. Notably, inhibiting of glycolysis with lower doses of 2-DG (1 mM), non-cytotoxic to MDA-MB-231 and HCC1937, was effective in diminishing invasiveness of aggressive BC cell lines. In contrast, 3-Nitropropionic acid (3-NA), an inhibitor of succinate dehydrogenase, the enzyme that oxidizes succinate to fumarate in TCA cycle, and functions as complex II of ETC, had no significant effect on their invasiveness, although levels of TCA metabolites or detection of mitochondrial membrane potential with JC-1 staining, indicated that INV cells originally had functional TCA cycles and membrane potential. ConclusionsHyper-glycolytic phenotype of invading cells caters to rapid energy production required for invasion while TCA cycle/ETC cater to cellular energy needs for sustenance in aggressive BC. Lower, non-cytotoxic doses of 2-DG can hamper invasion and can potentially be used as an adjuvant with other anti-cancer therapies without the usual side-effects associated with cytotoxic doses.
Genome-wide characterization and expression analysis&nbsp;of the heat shock transcription factor family&nbsp;in pumpkin&nbsp;(Cucurbita moschata)
Authors: Shen Changwei , Yuan Jingping 
Published: September 2020

Abstract
Background: Crop quality and yield are affected by abiotic and biotic stresses, and heat shock transcription factors ( Hsfs ) are considered to play important roles in regulating plant tolerance under various stresses. To investigate the response of Cucurbita moschata to abiotic stress, we analyzed the genome of Cucurbita moschata . Results: In this research, a total of 36 Cucurbita moschata Hsf ( CmHsf ) members were identified and classified into three subfamilies (I, II, and III) according to their amino acid sequence identity. The Hsfs of the same subfamily usually exhibit a similar gene structure (intron-exon distribution) and conserved domains (DNA-binding and other functional domains). Chromosome localization analysis showed that the 36 CmHsfs were unevenly distributed on 18 of the 21 chromosomes (except for Cm_Chr00, Cm_Chr08 and Cm_Chr20), among which 18 genes formed 9 duplicated gene pairs that have undergone segmental duplication events. The Ka/Ks ratio showed that the duplicated CmHsfs have mainly experienced strong purifying selection. High-level synteny was observed between Cucurbita moschata and other Cucurbitaceae species . Conclusions: The expression profile of CmHsfs in the roots, stems, cotyledons and true leaves revealed that the CmHsfs exhibit tissue specificity. The analysis of cis -acting elements and quantitative real-time polymerase chain reaction (qRT-PCR) revealed that some key CmHsf s were activated by cold stress, heat stress, hormones and salicylic acid. This study lays the foundation for revealing the role of CmHsfs in resistance to various stresses, which is of great significance for the selection of stress-tolerant Cucurbita moschata .

Abstract
We analyzed daily displacement time series from 34 continuous GPS stations in Nepal and 5 continuous GPS stations in South Tibet, China, and extracted the first 4.8 years of postseismic motion after the 2015 Mw7.8 Gorkha earthquake. With the longer duration GPS observations, we find that postseismic displacements mainly exhibit southward and uplift motion. To study the postseismic afterslip and viscoelastic relaxation, we built a 3-D spherical finite element model (FEM) with heterogeneous material properties and surface topography across the Himalayan range, accounting for the strong variations in material properties and surface elevation along central Himalayan arc. On the basis of the FEM, we reveal that the predicted viscoelastic relaxation of cm level moves southward to the north of the Gorkha earthquake rupture, but in an opposite direction to the observed postseismic deformation in the south; the postseismic deformation with viscoelastic relaxation is well explained by afterslip downdip of the coseismic rupture, which is still dominant 4.8 years after the 2015 Mw7.8 Gorkha earthquake. The lack of slip on a shallow portion and western segment of the MHT during and after the 2015 Gorkha earthquake implies continued seismic hazard in the future.

Abstract
Background Interest in the interplay between host genetics and the gut microbiome in complex human diseases is increasing, with prior evidence mainly being derived from animal models. In addition, the shared and distinct microbiome features among complex human diseases remain largely unclear.Results This analysis was based on a Chinese population with 1,475 participants. We estimated the SNP-based heritability, which suggested that Desulfovibrionaceae and Odoribacter had significant heritability estimates (0.456 and 0.476, respectively). We performed a microbiome genome-wide association study to identify host genetic variants associated with the gut microbiome. We then conducted bidirectional Mendelian randomization analyses to examine the potential causal associations between the gut microbiome and complex human diseases. We found that Saccharibacteria could potentially decrease the concentration of serum creatinine and increase the estimated glomerular filtration rate. On the other hand, atrial fibrillation, chronic kidney disease and prostate cancer, as predicted by host genetics, had potential causal effects on the abundance of some specific gut microbiota. For example, atrial fibrillation increased the abundance of Burkholderiales and Alcaligenaceae and decreased the abundance of Lachnobacterium, Bacteroides coprophilus, Barnesiellaceae, an undefined genus in the family Veillonellaceae and Mitsuokella. Further disease-microbiome feature analysis suggested that systemic lupus erythematosus and chronic myeloid leukaemia shared common gut microbiome features. Conclusions These results suggest that different complex human diseases share common and distinct gut microbiome features, which may help reshape our understanding of disease aetiology in humans.

Abstract
Background As we all know, patients with epithelial ovarian carcinoma have poor prognosis and high recurrence rate. It is critical and challenging to screen out the patients with high risk of recurrence. At present, there are some models predicting the overall survival of epithelial ovarian carcinoma, however, there is no widely accepted tool or applicable model predicting the recurrence risk of epithelial ovarian carcinoma patients. The objective of this study was to establish and verify a nomogram to predict the recurrence risk of EOC. Methods We reviewed the clinicopathological and prognostic data of 193 patients with EOC who achieved clinical complete remission after cytoreductive surgery and chemotherapy between January 2003 and December 2013 in Peking University First Hospital. The nomogram was established with the risk factors selected by LASSO regression. The medical data of 187 EOC patients with 5-year standard follow-up in Peking University Third Hospital and Beijing Obstetrics and Gynecology Hospital were used for external validation of the nomogram. AUC curve and Hosmer-Lemeshow test were used to evaluate the discrimination and calibration.Results The nomogram for 3-year recurrence risk was established with FIGO stage, histological grade, histological type, lymph node metastasis status and serum CA125 level at diagnosis. The total score can be obtained by adding the grading values of these factors together. The C statistics was 0.828 [95% CI, 0.764-0.884] and the Chi-square value is 3.6 (P=0.731>0.05) with the training group. When the threshold value was set at 198, the sensitivity, specificity, positive predictive value, negative predictive value and concordance index were 88.8%, 67.0%, 71.8%, 86.3% and 0.558 respectively. In the external validation, the C statistics was 0.803 [95%CI, 0.738-0.867] and the Chi-square value is 11.04 (P=0.135>0.05). With the threshold value of 198, the sensitivity, specificity, positive predictive value, negative predictive value and concordance index of the nomogram were 75.7%, 77.0%, 83.2%, 67.9%, and 0.52 respectively.Conclusions We established and validated a nomogram to predict 3-year recurrence risk of patients with EOC who achieved clinical complete remission after cytoreductive surgery and chemotherapy. This nomogram with good discrimination and calibration might be useful for screening out the patients with high risk of recurrence.
