The long COVID symptoms span various organ systems including the respiratory, cardiovascular, gastrointestinal, and neurological manifestations. Mitochondrial dysfunction and immune dysregulation play crucial roles in the long COVID pathophysiology. Recently nutritional intervention gained much attention in managing post-viral syndromes. Effective interventions like supplementation of omega-3 fatty acid, macro and micro nutrients, and vitamins help to reduce systemic inflammation and counteract muscle wasting. Other approaches like nutritional recovery, dietetic interventions, continuous nutritional care post-hospital discharge, nutritional rehabilitation programs,whole-diet approaches like Mediterranean diet, plant-based diet, and caloric optimization, improve overall functional recovery. Physical activity and exercise regimes have been shown to improve fatigue, dyspnea, and cognitive function. Tailored exercise regimes may promote safe rehabilitation. Certain ineffective interventions,such as non-personalized approaches, high dose of antioxidants, use of herbal products that are not clinically validated need to be addressed. Dietary interventions such as personalized nutritional counseling have been demonstrated to improve physical performance in long COVID patients. Further research is needed to refine protocols and identify optimal combinations of dietary and movement-based therapies to support the recovery of long-COVID patients. This narrative review focuses on the ongoing researches that reveals the intricate relationship between nutrition and long COVID recovery and also establishes effective protocols for nutritional care.展开更多

Various microbial species within the complex ecosystem of the microbiome have been shown to play important roles in disease. Identification of bioactive materials capable of altering the abundances of these species both safely and effectively is a major goal in microbiome research. Many traditional Chinese medicines (TCMs) have been reported to affect the composition of the gut microbiome. Here, we summarize studies that have used TCMs to alter the gut microbiome and discuss the response relationship between TCMs and gut microbial species. Methods: We searched the PubMed, Web of Science, and Knowledge Network databases using the terms “traditional Chinese medicine,” “gut microbiome,” and specific system disease names (endocrine, immune, nervous, cardiovascular, and digestive). Studies were excluded if irrelevant or if the experimental procedures were unclear. Results: TCMs have been reported to affect a wide range of gut microbial taxa spanning major phyla, including Firmicutes, Bacteroidetes, Proteobacteria, Verrucomicrobiota, Actinobacteria, and Fusobacteria. In all, 54 TCMs including compounds and extracts have been tested in rodents and 30 have been examined in human trials. Almost all studies have reported positive results in regulating the gut microbiome as well as modulating corresponding phenotypes, spanning diseases of the endocrine, immune, nervous, cardiovascular, and digestive systems. Gut species, including Akkermansia, Bacteroides, Fusobacterium, Faecalibacterium, and E. coli, were found to be regulated by 19 TCMs. A network was constructed to visualize the interactions between TCMs and these taxa. Conclusion: There exists a complex and close relationship between intestinal microflora and diseases. Sufficient experimental data and studies have proved that the imbalance of intestinal microflora affects health by mediating metabolism, immune regulation, inflammation and signal transduction. Many characteristic alterations of intestinal microflora are positively correlated with diseases, so intestinal microflora has become a potential risk index and treatment target for many diseases. Many TCMs affect the relative abundances of microbial species in the gut, and therefore may be useful for modulating the gut microbiome. This review provides a reference for prioritizing candidate TCMs from the enormous repertoire of such medicines to test which specific gut microbes are targeted.展开更多

文摘Microglia are the resident macrophages of the central nervous system.They act as the first line of defense against pathogens and play essential roles in neuroinflammation and tissue repair after brain insult or in neurodegenerative and demyelinating diseases(Borst et al.,2021).Together with infiltrating monocyte-derived macrophages,microglia also play a critical role for brain tumor development,since immunosuppressive interactions between tumor cells and tumor-associated microglia and macrophages(TAM)are linked to malignant progression.This mechanism is of particular relevance in glioblastoma(GB),the deadliest form of brain cancer with a median overall survival of less than 15 months(Khan et al.,2023).Therefore,targeting microglia and macrophage activation is a promising strategy for therapeutic interference in brain disease.
文摘Objective:To explore the impact of systematic stepwise rehabilitation nursing intervention on the prognosis and disease uncertainty of patients with hypertensive intracerebral hemorrhage,and to provide feasible strategies for clinical nursing.Methods:Eighty patients with hypertensive intracerebral hemorrhage admitted to our hospital from January 2023 to June 2025 were selected and randomly divided into an observation group(n=40,receiving systematic stepwise rehabilitation nursing)and a control group(n=40,receiving conventional nursing).The intervention effects were analyzed by comparing changes in the National Institutes of Health Stroke Scale(NIHSS)scores for neurological recovery,Short Form 36 Health Survey(SF-36)scores for quality of life,Exercise of Self-Care Agency Scale(ESCA)scores for self-management ability,compliance,and the Mishel Uncertainty in Illness Scale(MUIS)scores between the two groups.Results:All scores in the observation group were significantly better than those in the control group after the intervention(p<0.05).Specifically,the NIHSS scores decreased more significantly,the total SF-36 scores increased,the ESCA scores increased significantly,while the MUIS scores decreased significantly,and compliance improved markedly,indicating a reduction in disease uncertainty among patients.Conclusion:Systematic stepwise rehabilitation nursing intervention can significantly improve neurological recovery,quality of life,self-management ability,and compliance in patients with hypertensive intracerebral hemorrhage,while effectively reducing disease uncertainty.It is worthy of clinical promotion and application.
文摘BACKGROUND Approximately 30%of patients with head and neck cancer experience adverse effects caused by anxiety and depression.Considering the high prevalence,implementing customized interventions to ease adverse emotional states is imperative.AIM To evaluate the efficacy of cognitive behavioral therapy(CBT)-based psychological interventions in improving the psychological well-being and quality of life(QoL)of patients with laryngeal carcinoma.METHODS This study enrolled 120 patients admitted from February 2022 to February 2024.The control group,comprising 50 participants,received standard supportive psychological care,while the research group,consisting 70 participants,underwent CBT-based interventions.Several clinical outcomes were systematically assessed that included postoperative recovery metrics(duration of tracheostomy and nasogastric tube dependence and length of hospitalization),psychological status(Self-Rating Anxiety Scale and Self-Rating Depression Scale),nutritional markers(serum albumin and hemoglobin levels),sleep quality(Self-Rating Scale of Sleep and Athens Insomnia Scale),and QoL(Functional Assessment of Cancer Therapy-Head and Neck).RESULTS The results demonstrated that the research group experienced superior outcomes,with significantly reduced durations of tracheostomy and nasogastric tube dependence,as well as shorter hospital stays,compared with the control group.Additionally,the research group exhibited markedly lower post-intervention Self-Rating Anxiety Scale,Self-Rating Depression Scale,Self-Rating Scale of Sleep,and Athens Insomnia Scale scores,along with minimal but higher change in serum albumin and hemoglobin levels compared with the control group.All five domains of Functional Assessment of Cancer Therapy-Head and Neck showed notable improvements in the research group,exceeding those observed in the control group.CONCLUSION CBT-based psychological support positively affects the mental well-being and QoL of patients with laryngeal carcinoma,highlighting its potential for broader clinical application.
文摘Background:Early Hearing Detection and Intervention(EHDI)plays a critical role in improving language,cognitive,and socio-emotional outcomes for infants with hearing loss.In Nigeria,however,EHDI implementation remains limited by fragmented service delivery,uneven technological capacity,and sociocultural factors that delay timely diagnosis.This study explored the perspectives of paediatric audiologists and parents to provide a comprehensive understanding of the opportunities and challenges influencing early hearing care across diverse Nigerian settings.Methods:A mixed-methods design was employed across audiology facilities selected systematically from four Nigerian geopolitical zones.Twenty-five paediatric audiologists and twenty-three parents of children with congenital hearing loss participated.Quantitative data were collected using a structured questionnaire assessing awareness,diagnostic access,and intervention experiences.Qualitative data were obtained through semi-structured interviews and two focus group discussions.Thematic analysis followed Braun and Clarke's six-step framework,with dual coding,external auditing,and member validation to enhance credibility.Results:Quantitative findings demonstrated broad agreement on the diagnostic value of otoacoustic emissions(OAEs)and automated auditory brainstem responses(AABRs),the developmental benefits of early intervention,and the importance of active parental involvement.However,respondents identified persistent barriers including high costs of screening and therapy,poor public awareness of early hearing loss symptoms,and a critical shortage of trained personnel,and unequal distribution of diagnostic tools,particularly in rural and northern regions.Thematic analysis further underscored disparities in diagnostic capacity,sociocultural interpretations of deafness that delay clinical consultation,and economic constraints that hinder continuity of care.While families who accessed early intervention reported improved communication,social engagement,and learning readiness in their children,systemic gaps continue to limit widespread success.Conclusions:Despite growing technological capacity and awareness of EHDI benefits,significant structural,financial,and sociocultural challenges continue to impede timely diagnosis and intervention in Nigeria.Strengthening national policies,ensuring equitable distribution of diagnostic tools,expanding professional training,subsidising services,implementing culturally sensitive awareness campaigns and integration of Universal Newborn Hearing Screening into routine postnatal care are essential to improving outcomes for deaf infants.
文摘Healthy life expectancy is a pivotal measure of population health by integrating both life expectancy and the quality of years lived.A significant increase in life expectancy was evident in most populations during the past decades worldwide[1],but the growth in healthy life expectancy has generally lagged behind[2].China has made substantial strides in enhancing both life expectancy and healthy life expectancy.
文摘BACKGROUND Low anterior resection syndrome(LARS)is a prevalent and debilitating complication following sphincter-preserving surgery for rectal cancer.Evidence-based interventions for the concurrent psychological burden are limited.Electroacupuncture has been proposed as a potential adjunctive therapy,but its psychological benefits remain inadequately studied.AIM To investigate the therapeutic effect of electroacupuncture on emotional recovery and gastrointestinal function in patients with moderate to severe LARS,and to explore its potential advantages in psychologically vulnerable subgroups.METHODS We conducted a retrospective,controlled study involving 100 patients with moderate to severe LARS(LARS score≥21)treated at two tertiary hospitals in China between January 2022 and December 2024.Patients received either standard postoperative care alone(n=50)or in combination with a standardized 4-week electroacupuncture protocol(n=50).Psychological and functional outcomes were assessed using validated instruments including Hospital Anxiety and Depression Scale(HADS),Body Image Scale(BIS),General Self-Efficacy Scale,Perceived Social Support Scale(PSSS),LARS score,and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at four time points.The primary endpoint was emotional remission,defined as a≥3-point reduction in HADS-Anxiety subscale(HADS-A).Analyses included repeated-measures comparisons,Kaplan-Meier survival curves,Cox regression models,and subgroup-interaction testing.RESULTS At baseline,demographic,surgical,and psychosocial characteristics were comparable among groups.By week 4,patients receiving electroacupuncture demonstrated significantly greater reductions in anxiety(HADS-A:4.8±2.6 vs 7.3±3.0;P<0.001),depression,and body-image disturbance(BIS:8.7±3.6 vs 11.9±4.2;P<0.001),alongside enhanced coping capacity(Brief Coping Orientation to Problems Experienced),perceived social support(PSSS),and bowel function(LARS score).Emotional remission-defined as a≥3-point HADS-A reduction-was achieved more rapidly in the electroacupuncture group,as confirmed by Kaplan-Meier analysis(log-rank P<0.001;odds ratio=4.7).Multivariate Cox regression identified higher baseline LARS and BIS scores as independent predictors of delayed emotional recovery.Subgroup analyses revealed significantly amplified treatment benefits in patients with high baseline anxiety(HADS-A≥8),elevated body-image disturbance(BIS≥12),or low perceived social support(PSSS<60),with consistent interaction effects(P for interaction<0.05 across subgroups).CONCLUSION Electroacupuncture may accelerate emotional recovery and improve functional and psychosocial outcomes in patients with LARS.Its integration into postoperative care may offer particular benefits for psychologically vulnerable subgroups.

文摘Advanced biological systems are characterized by dynamic,complex,and functional biointerfaces.Human skin,for example,exemplifies such a biointerface,featuring diverse micro-and nano-scale surface structures.It serves as an ideal window for bioelectronic devices to acquire vital physiological information,enabling continuous health monitoring,and disease intervention.
文摘Situs inversus totalis(SIT)is a rare congenital anomaly in which the major organs are reversed from their normal positions.In patients with SIT,the right-lobe graft must be placed in the left upper quadrant(LUQ).However,hepatic outflow obstruction is a critical issue,often requiring radiologic intervention because of compression or kinking following graft regeneration of the vessels[1–3].Therefore,preoperative planning is essential to address the challenges of graft placement and vein reconstruction.Despite these complexities,we previously reported techniques using a reversed modified right-lobe(mRL)graft from a donor in a conventional recipient with SIT[2].Here,we successfully applied a similar concept.

文摘Oxidative stress significantly contributes to secondary damage after spinal cord injury.Despite its importance,research on oxidative stress in spinal cord injury remains limited.Investigating the expression and regulation of oxidative stress-related genes could enhance the diagnosis and treatment of spinal cord injury.In this study,we analyzed the sequencing data of human blood samples and injured mouse spinal cord tissue that were sourced from GEO databases and identified diagnostic biomarkers associated with the severity of spinal cord injury.We also explored the expression patterns of oxidative stress-related genes,potential regulatory mechanisms,and therapeutic drugs.To validate our findings,we performed immunofluorescence and quantitative polymerase chain reaction to assess gene expression in the injured spinal cord.Our results revealed biomarkers associated with oxidative stress and immune responses across different levels of spinal cord injury in humans.We identified differentially expressed oxidative stress-related genes and key hub genes in injured mouse spinal cord tissue and revealed their temporal expression patterns at both the tissue and single-cell levels.We also clarified the signaling pathways associated with oxidative stress and identified ligand-receptor pairs among various cell types at different time points after injury.Furthermore,we discovered microRNAs,long non-coding RNAs,and transcription factors that regulate these hub genes and revealed their roles in modulating gene expression at various stages after spinal cord injury.We also identified drugs targeting these hub genes.The findings from this study not only aid in identifying diagnostic biomarkers that reflect the severity of spinal cord injury,but also provide insights into the expression dynamics of oxidative stress-related genes.In addition,the study reveals potential regulatory mechanisms and identifies potential drugs to treat patients with spinal cord injury.

文摘The utilization and storage of CO_(2) emissions from oil production and consumption in the upstream oil industry will contribute to sustainable development.CO_(2) flooding is the key technology for the upstream oil industry to transition to sustainable development.However,there is a significant challenge in achieving high recovery and storage efficiency in unconventional reservoirs,particularly in underde-veloped countries.Numerous studies have indicated that the limited sweep range caused by premature gas channeling of CO_(2) is a crucial bottleneck that hinders the enhancement of recovery,storage efficiency and safety.This review provides a comprehensive summary of the research and technical advancements regarding the front sweep characteristics of CO_(2) during migration.It particularly focuses on the char-acteristics,applicable stages,and research progress of different technologies used for regulating CO_(2) flooding sweep.Finally,based on the current application status and development trends,the review offers insights into the future research direction for these technologies.It is concluded that the front migration characteristics of CO_(2) play a crucial role in determining the macroscopic sweep range.The focus of future research lies in achieving cross-scale correlation and information coupling of CO_(2) migration processes.Currently,the influence weight of permeability,injection speed,pressure and other parameters on the characteristics of‘fingering-gas channeling’is still not well clear.There is an urgent need to establish prediction model and early warning mechanism that considers multi-parameters and cross-scale gas channeling degrees,in order to create effective strategies for prevention and control.There are currently three technologies available for sweep regulation:flow field intervention,mobility reduction,and gas channeling plugging.To expand the sweep effectively,it is important to systematically integrate these technologies based on their regulation characteristics and applicable stages.This can be achieved by constructing an intelligent synergistic hierarchical segmented regulation technology known as‘flow field intervention+mobility regulation+channel plugging chemically’.This work is expected to provide valuable insights for achieving conformance control of CO_(2)-EOR and safe storage of CO_(2).
