In the TCGA cohort, high CD68 mRNA levels were associated with better outcome (p = 0.02). Macrophages enhanced FOLFOX cytotoxicity on CRC cells (p less then 0.01), and drugs oriented macrophage polarization from M2- to M1-phenotype. Low TAM densities identify stage III CRC patients at higher risk of recurrence after adjuvant therapy, and macrophages can augment the chemo-sensitivity of micro-metastases.The purpose of this study was to compare the reconstructive outcomes of soft-tissue defects around the foot and ankle with anterolateral thigh (ALT) flap or lateral supramalleolar (LSM) flap and attempt to provide an optimal strategy for elderly patients. A retrospective review of all continuous patients with foot and ankle reconstruction using different flaps from October of 2010 and October of 2020 was performed. Based on the flap types, the patients were divided into two groups ALT flap group (n = 50) and LSM flap group (n = 46). Outcomes were assessed according to the flap survival rate, early complications, general complications, late complications, cosmetic appearance, functional outcomes and Vancouver Scar Scale (VSS). We found that there was no difference in average age, gender, aetiology, size of the defect, debridement times between the two groups; however, a significant difference in operation time, hospitalisation time and cost were noted between them. What’s more, the early flap complications between them were not significantly different. The LSM flap group showed less general complications, less flap bulky and lower cosmetic appearance. Moreover, the functional evaluation and VSS seem similar (P > .05). Thus, The ALT flap and LSM flap are both flaps available for foot and ankle reconstruction in elderly patients. However, the LSM flap offers short operation time, short hospitalisation time, and less cost with a lower frequency of postoperative complications. Thus, we advocate the LSM flap for the reconstruction of moderate-size defects of the foot and ankle region in elderly patients.
Rett syndrome (RTT) is a rare neurodevelopmental disorder associated with pathogenic MECP2 variants. Because the MECP2 gene is subject to X-chromosome inactivation (XCI), factors including MECP2 genotypic variation, tissue differences in XCI, and skewing of XCI all likely contribute to the clinical severity of individuals with RTT.
We analyzed the XCI patterns from blood samples of 320 individuals and their mothers. It includes individuals with RTT (n=287) and other syndromes sharing overlapping phenotypes with RTT (such as CDKL5 Deficiency Disorder [CDD, n=16]). XCI status in each proband/mother duo and the parental origin of the preferentially inactivated X chromosome were analyzed.
The average XCI ratio in probands was slightly increased compared to their unaffected mothers (73% vs. 69%, p=.0006). Among the duos with informative XCI data, the majority of individuals with classic RTT had their paternal allele preferentially inactivated (n=180/220, 82%). In sharp contrast, individuals with CDD had their maternal allele preferentially inactivated (n=10/12, 83%). Our data indicate a weak positive correlation between XCI skewing ratio and clinical severity scale (CSS) scores in classic RTT patients with maternal allele preferentially inactivated XCI (r
=0.35, n=40), but not in those with paternal allele preferentially inactivated XCI (r
=-0.06, n=180). The most frequent MECP2 pathogenic variants were enriched in individuals with highly/moderately skewed XCI patterns, suggesting an association with higher levels of XCI skewing.
These results extend our understanding of the pathogenesis of RTT and other syndromes with overlapping clinical features by providing insight into the both XCI and the preferential XCI of parental alleles.

This study aims to investigate the role of echocardiographically determined left ventricular output indices on sacubitril/valsartan titration in a cohort of outpatients with heart failure and reduced ejection fraction (HFrEF).
We analysed 106 HFrEF patients who underwent echocardiography examination up to 1week before starting treatment with sacubitril/valsartan. For each patient, a comprehensive list of clinical and laboratory parameters was collected, and stroke volume index (SVi), cardiac index, and flow rate were calculated. The primary endpoint was the occurrence of complete titration of sacubitril/valsartan. The secondary endpoint was the incidence of adverse events (hypotension and renal adverse events). Univariate and multivariate logistic regression were used to identify variables associated with the primary and secondary endpoints. Mean age of patients was 73.7±10.4years, 72 patients (71.7%) had ischaemic aetiology of HF, and mean ejection fraction was 29.4±5.9%. At multivariate analysis, SVi [odds ratio (OR) 1.43 per 5mL/m
increase, 95% confidence interval (CI) 1.03-1.97; P=0.028], serum sodium (OR 1.18, 95% CI 1.02-1.37; P=0.022), and haemoglobin (OR 1.73, 95% CI 1.25-2.40; P=0.001) were found to be independent predictors of titration during follow-up. Multivariate analysis for the secondary endpoint showed SVi (OR 0.63 per 5mL/m
increase, 95% CI 0.44-0.90; P=0.012) and New York Heart Association Class III (OR 2.65, 95% CI 1.07-6.5; P=0.034) to be associated with hypotension.
Stroke volume index is positively associated with complete titration of sacubitril/valsartan. Patients with low SVi are more prone to experience hypotension during titration.

Caffeine is often used as a stimulant during fatigue, but the standard of characteristic physiological indicators of the effect of caffeine on neuromuscular fatigue has not been unified. The purpose of this systematic review and meta-analysis is to summarize current experimental findings on the effects of caffeine on physiological indexes before and after neuromuscular fatigue, identify some characteristic neuromuscular physiological indexes to assess the potential effects of caffeine.
The Preferred Reporting Items for Systematic Reviews and Meta-analyses are followed. We systematically searched PubMed, Google academic, and Web of Science for randomized controlled trials. We searched for studies on caffeine’s (i) effects on neuromuscular fatigue and (ii) the influence of physiological indexes changes. Meta-analysis was performed for standardized mean differences (SMD) between caffeine and placebo trials in individual studies.
The meta-analysis indicated that caffeine significantly improves voluntary acttake had a big effect on the electromyogram (EMG) and peak power (PP), and its effect role needs to be further verified, this conclusion tends to indicate the effect of caffeine on neuromuscular fatigue during jumping or elbow bending moment movements. HR, VO2 , maximal voluntary contraction (MVC) cannot be used as the characteristic indexes of caffeine on neuromuscular fatigue. This conclusion tends to indicate the effect of caffeine on neuromuscular fatigue during endurance exercise. However, the results of meta-analysis are based on limited evidence and research scale, as well as individual differences of participants and different physical tasks, so it is necessary to interpret the results of meta-analysis cautiously. Therefore, future research needs to explore other physiological indicators and their indicative effects in order to determine effective and accurate characteristic indicators of caffeine on neuromuscular fatigue.
Sex workers are disproportionately impacted by the HIV pandemic across global contexts, in part due to social and structural contexts of stigma and criminalization. Among women living with HIV, there is a dearth of longitudinal information regarding dynamics of sex work engagement and associated social and health outcomes. In order to better understand the social contexts and health needs of sex working women living with HIV, this study aimed to understand recent sex work prevalence and its longitudinal associations with stigma, psychosocial and clinical HIV outcomes among women living with HIV in Canada.
We conducted a three-wave prospective cohort survey at 18-month intervals with women living with HIV aged 16 and older in three Canadian provinces between 2013 and 2018. We used generalized estimating equations to examine longitudinal associations between recent (past 6-month) sex work with three types of outcomes psychosocial (recent violence, recent injection drug use, hazardous alcohol use, clinical digma.
Among women living with HIV in Canada, sex work engagement is dynamic, and sex workers are more likely to report recent violence, recent injection drug use, problematic alcohol use and clinical depression. Violence prevention and support, harm reduction, mental health promotion and sex work-affirming programs could be employed to optimize health and rights for sex working women living with HIV.

However, the unpleasant induced dyspnoea inevitably impedes its clinical application. Thus, it is urgent to elucidate the mechanism underlying the ZTO-induced dyspnoea. In this study, network pharmacology was firstly performed to search the clue of ZTO-induced dyspnoea. The key target genes of ZTO-induced dyspnoea were analysed using GO enrichment analysis and KEGG pathway analysis. GO analysis suggested that haem binding could be a key molecular function involved in ZTO-induced dyspnoea. Hence, the haemoglobin (Hb) was focused for its oxygen-carrying capacity with haem as its critical component binding to the oxygen. Ultraviolet-visible absorption spectrum indicated that the ZTO injection (ZTOI) perturbed the Soret band of Hb, suggesting an interaction between ZTO and Hb. GC-MS analysis revealed that β-elemene, germacrone, curdione and furanodiene were main components of ZTOI. Molecular docking was used to illustrate the high affinity between representative sesquiterpenes and Hb, which was finally confirmed by surface plasmon resonance, suggesting their potential roles in dyspnoea by ZTO. Following a network pharmacology-driven strategy, our study revealed an intervened Hb-based mechanism underlying the ZTO-induced dyspnoea, providing a reference for elucidating mechanism underlying adverse drug reactions of herbal medicines in clinic.Cell-to-cell communication within the heterogeneous solid tumor environment plays a significant role in the uncontrolled metastasis of cancer. To inhibit the metastasis and growth of cancer cells, various chemically designed and biologically derived nanosized biomaterials have been applied for targeted cancer therapeutics applications. Over the years, bioinspired soft nanovesicles have gained tremendous attention for targeted cancer therapeutics due to their easy binding with tumor microenvironment, natural targeting ability, bio-responsive nature, better biocompatibility, high cargo capacity for multiple therapeutics agents, and long circulation time. These cell-derived nanovesicles guard their loaded cargo molecules from immune clearance and make them site-selective to cancer cells due to their natural binding and delivery abilities. Furthermore, bioinspired soft nanovesicles prevent cell-to-cell communication and secretion of cancer cell markers by delivering the therapeutics agents predominantly. Cell-derived vesicles, namely, exosomes, extracellular vesicles, and so forth have been recognized as versatile carriers for therapeutic biomolecules.
