Resveratrol combats chronic diseases through enhancing mitochondrial quality

Resveratrol(RSV),as a functional food component extracted from natural plants,has been widely studied and recognized in preventing and treating various diseases,with major mechanisms including executing anti-inflammation and anti-oxidation functions,and improving mitochondrial quality.Chronic diseases as non-communicable diseases are mainly caused by multiple factors,such as physiological decline and dysfunction in the body,and have become a significant challenge on public health worldwide.It is worth noting that chronic diseases such as Alzheimer's disease(AD),Parkinson's disease(PD),muscle atrophy,cardiovascular disease,obesity,and cancer are accompanied by abnormal mitochondrial function.Therefore,targeted regulation of mitochondria may be a meaningful way to prevent and treat chronic diseases.Increasing evidence has confirmed that RSV is actively involved in regulating mitochondria,and it has become an essential consideration to prevent and treat chronic diseases through targeting mitochondria and improving corresponding functions.In this article,current studies on RSV to optimize mitochondrial quality for preventing and alleviating chronic disease are systematically summarized,which can provide a theoretical reference for the development of functional foods or drugs to combat chronic diseases.

Seasonal variation in dietary intake and its association with obesity-related chronic diseases in northeast China

Objective:The objective of this study was to assess seasonal changes in dietary and nutrient intake of residents(18-75 years old)in Northeast China during summer and winter,and to explore the associations between fatty acids,phytosterols,and the prevalence of obesity-related chronic diseases,particularly obesity,hyperlipidemia,and NAFLD.Methods:A total of 4773 participants from the Internet-based Dietary Questionnaire for Chinese(IDQC)were included in this study.Dietary intake information was collected using a validated food frequency questionnaire.Student's t-test or Mann-Whitney U-test was used to analyze continuous variables,while Chi-squared tests were used to compare categorical variables.Multivariable logistic regression was employed to assess the relationship between fatty acids,phytosterols,and obesity-related chronic diseases.Results:The mean consumption of legumes,vegetables,fruits,nuts,dairy products,fish,condiments,energy,protein,fat,and carbohydrate differed significantly between summer and winter(P<0.05).Significant inverse associations were found between both fatty acids and phytosterols and obesity-related chronic diseases in multivariate adjusted models.Summer polyunsaturated fatty acid(PUFA)intake was negatively associated with the prevalence of hyperlipidemia(Q4,OR,0.515;95%CI,0.283-0.921;P<0.05)and non-alcoholic fatty liver disease(NAFLD)(Q4,OR,0.331;95%CI,0.176-0.599;P<0.001).Phytosterols intake was negatively associated with the prevalence of obesity(Q4,OR,0.603;95%CI,0.414-0.873;P<0.05),hyperlipidemia(Q4,OR,0.420;95%CI,0.233-0.731;P<0.001),and NAFLD(Q4,OR,0.206;95%CI,0.111-0.360;P<0.001)during the summer.Conclusions:Higher PUFA intake was associated with a lower prevalence of obesity,hyperlipidemia,and NAFLD.Phytosterol intake was inversely associated with the prevalence of hyperlipidemia and NAFLD.These findings suggest that the associations between PUFA and phytosterols and the prevalence of obesity-related chronic diseases may be influenced by seasonal differences in food intake.

Association of physical activity with risk of chronic kidney disease in China:A population-based cohort study

Background:Information on the association between physical activity(PA)and the risk of chronic kidney disease(CKD)is limited.We aimed to explore the associations of total,domain-specific,and intensity-specific PA with CKD and its subtypes in China.Methods:The study included 475,376 adults from the China Kadoorie Biobank aged 30-79 years during 2004-2008 at baseline.An interviewer-administered questionnaire was used to collect the information about PA,which was quantified as metabolic equivalent of task hours per day(MET-h/day)and categorized into 4 groups based on quartiles.Cox regression was used to analyze the association between PA and CKD risk.Results:During a median follow-up of 12.1 years,5415 incident CKD cases were documented,including 1159 incident diabetic kidney disease(DKD)cases and 362 incident hypertensive nephropathy(HTN)cases.Total PA was inversely associated with CKD risk,with an adjusted hazard ratio(HR,95%confidence interval(95%CI))of 0.83(0.75-0.92)for incident CKD in the highest quartile of total PA as compared with participants in the lowest quartile.Similar results were observed for risk of DKD and HTN,and the corresponding HRs(95%CIs)were 0.75(0.58-0.97)for DKD risk and 0.56(0.37-0.85)for HTN risk.Increased nonoccupational PA,low-intensity PA,and moderate-to-vigorous-intensity PA were significantly associated with a decreased risk of CKD,with HRs(95%CIs)of 0.80(0.73-0.88),0.85(0.77-0.94),and 0.85(0.76-0.95)in the highest quartile,respectively.Conclusion:PA,including nonoccupational PA,low-intensity PA,and moderate-to-vigorous-intensity PA,was inversely associated with the risk of CKD,including DKD,HTN,and other CKD,and such associations were dose dependent.

Risk factors for cognitive impairment in patients with chronic kidney disease

BACKGROUND Chronic kidney disease(CKD)patients have been found to be at risk of concurrent cognitive dysfunction in previous studies,which has now become an important public health issue of widespread concern.AIM To investigate the risk factors for concurrent cognitive dysfunction in patients with CKD.METHODS This is a prospective cohort study conducted among patients with CKD between October 2021 and March 2023.A questionnaire was formulated by literature review and expert consultation and included questions about age,sex,education level,per capita monthly household income,marital status,living condition,payment method,and hypertension.RESULTS Logistic regression analysis showed that patients aged 60-79 years[odds ratio(OR)=1.561,P=0.015]and≥80 years(OR=1.760,P=0.013),participants with middle to high school education(OR=0.820,P=0.027),divorced or widowed individuals(OR=1.37,P=0.032),self-funded patients(OR=2.368,P=0.008),and patients with hypertension(OR=2.011,P=0.041)had a higher risk of cognitive impairment.The risk of cognitive impairment was lower for those with a college degree(OR=0.435,P=0.034)and married individuals.CONCLUSION The risk factors affecting cognitive dysfunction are age,60-79 years and≥80 years;education,primary school education or less;marital status,divorced or widowed;payment method,selffunded;hypertension;and CKD.

Heat exposure and hospitalizations for chronic kidney disease in China: a nationwide time series study in 261 major Chinese cities

Background:Climate change profoundly shapes the population health at the global scale.However,there was still insufficient and inconsistent evidence for the association between heat exposure and chronic kidney disease(CKD).Methods:In the present study,we studied the association of heat exposure with hospitalizations for cause-specific CKD using a national inpatient database in China during the study period of hot season from 2015 to 2018.Standard time-series regression models and random-effects Meta-analysis were developed to estimate the city-specific and national averaged associations at a 7 lag-day span,respectively.Results:A total of 768,129 hospitalizations for CKD was recorded during the study period.The results showed that higher temperature was associated with elevated risk of hospitalizations for CKD,especially in sub-tropical cities.With a 1℃ increase in daily mean temperature,the cumulative relative risks(RR)over lag 0-7 d were 1.008[95% confidence interval(CI)1.003-1.012]for nationwide.The attributable fraction of CKD hospitalizations due to high temperatures was 5.50%.Stronger associations were observed among younger patients and those with obstructive nephropathy.Our study also found that exposure to heatwaves was associated with added risk of hospitalizations for CKD compared to non-heatwave days(RR=1.116,95%CI 1.069-1.166)above the effect of daily mean temperature.Conclusions:Short-term heat exposure may increase the risk of hospitalization for CKD.Our findings provide insights into the health effects of climate change and suggest the necessity of guided protection strategies against the adverse effects of high temperatures.

Clinical features of chronic kidney disease in dogs with the serological presence of Leptospira spp.,Ehrlichia canis,and Anaplasma phagocytophilum

Chronic kidney disease is commonly diagnosed in dogs,and clinical signs may be aggravated when infected agents are involved.In this case report,33 dogs with chronic kidney disease were clinically evaluated and serologically tested for Leptospira spp.,Ehrlichia canis,and Anaplasma phagocytophilum.The seroprevalence for Leptospira spp.was 39.4%.The most frequent serovars found were Pyrogenes,Canicola,Bratislava and Australis,with serological titers between 1:100 to 1:800.Clinical signs included fever,depression,decreased body condition,vomiting and hema‑turia.Signifcant laboratory fndings were anemia,leukocytosis,thrombocytopenia,increased liver enzymes,urea and creatinine,hyperbilirubinemia and hyperphosphatemia.All leptospira seronegative dogs were positive for one or both monitored homoparasites(i.e.,E.canis and A.phagocytophilum);only three leptospira seropositive dogs were positive for one or both hemoparasites.Findings also suggest that endemic hemoparasites of dogs should be moni‑tored in dogs with a kidney condition for a better clinical picture of the patients and therapeutic approach.

Bone loss in chronic liver diseases:Could healthy liver be a requirement for good bone health?

Given that the liver is involved in many metabolic mechanisms,it is not surprising that chronic liver disease(CLD)could have numerous complications.Secondary osteoporosis and increased bone fragility are frequently overlooked complications in CLD patients.Previous studies implied that up to one-third of these individuals meet diagnostic criteria for osteopenia or osteoporosis.Recent publications indicated that CLD-induced bone fragility depends on the etiology,duration,and stage of liver disease.Therefore,the increased fracture risk in CLD patients puts a severe socioeconomic burden on the health system and urgently requires more effective prevention,diagnosis,and treatment measures.The pathogenesis of CLD-induced bone loss is multifactorial and still insufficiently understood,especially considering the relative impact of increased bone resorption and reduced bone formation in these individuals.It is essential to note that inconsistent findings regarding bone mineral density measurement were previously reported in these individuals.Bone mineral density is widely used as the“golden standard”in the clinical assessment of bone fragility although it is not adequate to predict individual fracture risk.Therefore,microscale bone alterations(bone microstructure,mechanical properties,and cellular indices)were analyzed in CLD individuals.These studies further support the thesis that bone strength could be compromised in CLD individuals,implying that an individualized approach to fracture risk assessment and subsequent therapy is necessary for CLD patients.However,more well-designed studies are required to solve the bone fragility puzzle in CLD patients.

Improving Prediction of Chronic Kidney Disease Using KNN Imputed SMOTE Features and TrioNet Model

Chronic kidney disease(CKD)is a major health concern today,requiring early and accurate diagnosis.Machine learning has emerged as a powerful tool for disease detection,and medical professionals are increasingly using ML classifier algorithms to identify CKD early.This study explores the application of advanced machine learning techniques on a CKD dataset obtained from the University of California,UC Irvine Machine Learning repository.The research introduces TrioNet,an ensemble model combining extreme gradient boosting,random forest,and extra tree classifier,which excels in providing highly accurate predictions for CKD.Furthermore,K nearest neighbor(KNN)imputer is utilized to deal withmissing values while synthetic minority oversampling(SMOTE)is used for class-imbalance problems.To ascertain the efficacy of the proposed model,a comprehensive comparative analysis is conducted with various machine learning models.The proposed TrioNet using KNN imputer and SMOTE outperformed other models with 98.97%accuracy for detectingCKD.This in-depth analysis demonstrates the model’s capabilities and underscores its potential as a valuable tool in the diagnosis of CKD.

Meta-analysis of the association between chronic periodontitis and chronic kidney disease

BACKGROUND Many scholars have performed several clinical studies have investigated the association between chronic periodontitis(CP)and chronic kidney disease(CKD).However,there are still differences between these research results,and there is no unified conclusion.Therefore,a systematic review is required to understand this issue fully.AIM To explore the correlation between CP and CKD.METHODS Literature on the correlation between CP and CKD,as well as the clinical attachment level(CAL)and pocket probing depth(PPD)of CKD and non-CKD,were retrieved from PubMed,Embase,the Cochrane Library,and Web of Science repositories until January 2024.After the effective data were extracted,data processing and statistics were performed using Stata 12.0.RESULTS Of the 22 studies,13 were related to CP and CKD,and 9 reported CAL and PPD in patients with CKD and healthy controls.Meta-analysis of the correlation between CP and CKD revealed that CKD probability in people with CP was 1.54 times that of healthy individuals[relative risk=1.54,95%confidence interval(CI):1.40-1.70],and CP incidence in patients with CKD was 1.98 times that of healthy individuals[overall risk(OR)=1.98,95%CI:1.53-2.57].Meta-analysis of CAL and PPD evaluations between CKD patients and healthy individuals showed that CAL and PPD levels were higher in CKD patients[standard mean difference(SMD)of CAL=0.65,95%CI:0.29-1.01;SMD of PPD=0.33,95%CI:0.02-0.63].CONCLUSION A bidirectional association exists between CP and CKD.CKD risk is increased in CP patients and vice versa.Periodontal tissue or tooth loss risks increase over time in CKD patients.

Periodontitis and chronic kidney disease:A bidirectional relationship based on inflammation and oxidative stress

Chronic kidney disease(CKD)and chronic periodontitis(CP)are prevalent conditions which significantly impact public health worldwide.Both diseases share inflammatory and oxidative stress mechanisms,an indication of a likely bidirectional relationship.This editorial explored the association between CKD and CP by highlighting common inflammatory mechanisms and recent research findings that address this interrelationship.Through reviews of recent studies,we discussed how periodontal bacteria may activate systemic immune responses that affect both periodontal and renal tissues.Additionally,meta-analysis data indicated an increased risk of CKD development in patients with CP,and vice versa.The results suggest the need for more rigorous research in the future in order to address the confounding factors and evaluate specific periodontal health interventions and their direct effects on kidney function.We emphasized the importance of comprehensive and multidisciplinary care for the improvement of the overall health of patients affected by CP and CKD.

Classical bovine spongiform encephalopathy and chronic wasting disease:two sides of the prion coin

Transmissible spongiform encephalopathies(TSEs)are a group of progressive and ultimately fatal neurologic diseases of man and animals,all resulting from the propagated misfolding of the host's normal cellular prion protein.These diseases can be spontaneous,heritable,anthropogenic/iatrogenic,or in some cases horizontally transmissible,and include such notable TSEs as bovine spongiform encephalopathy(BSE)of cattle and chronic wasting disease(CWD)of cervids.Although they are both unequivocally protein misfolding disorders,they differ markedly in their pathogenesis,transmissibility,and zoonotic potential.While the BSE epidemic has largely abated over the past three decades following global feed bans on ruminant meat and bone meal,CWD,which is readily transmitted through various forms of excreta,has rapidly expanded from its original endemic zone to encompass much of North America,along with recently identified foci in Scandinavia.Most importantly,although the classical form of BSE has proven transmissible to humans consuming contaminated beef or beef products,so far there have been no conclusive reports on the zoonotic transmission of cWD to humans.The underlying basis for these differences-whether host or agent directed-are not well understood,though may be due to inherent differences in the three-dimensional structure of the misfolded BSE or CWD prion proteins or the expression levels and tissue distribution of respective cellular prion proteins.With the uncontrolled geographic spread of CWD,it is imperative that we improve our understanding of the factors governing prion disease pathogenesis,transmission,and zoonotic potential.

Impact of metabolic dysfunction-associated steatotic liver disease on the efficacy of immunotherapy in patients with chronic hepatitis B-related hepatocellular carcinoma

Objective:To investigate the impact of metabolic dysfunction-associated steatotic liver disease(MASLD)on the efficacy of immune checkpoint inhibitor(ICI)-based therapy in patients with chronic hepatitis B(CHB)-related hepatocellular carcinoma(HCC).Methods:A total of 155 patients with CHB-related HCC who received ICI–based therapy(in the Department of Hepatology,Tianjin Second People’s Hospital and Department of Hepatobiliary Oncology,Tianjin Medical University Cancer Institute&Hospital)between April 2021 and December 2023 were evaluated.Patients were divided into two groups:MASLD concurrent with CHB[MASLD-CHB](n=38),and CHB(n=117).Results:The median progression-free survival(PFS,6.9 months vs.9.3 months;P=0.001),progressive disease(57.89%vs.37.61%;P=0.028),and disease control rate(42.11%vs.62.39%;P=0.028)in the MASLD-CHB group were significantly worse than the CHB group.The median overall survival was not attained.The percentage of CD4+PD1+(17.56%vs.8.89%;P<0.001)and CD8+PD1+T cells(10.50%vs.7.42%;P=0.005)in patient samples from the MASLD-CHB group were significantly higher than the CHB group.Concurrent MASLD[hazard ratio(HR)=1.921;95%CI,1.138–3.245;P=0.015]and alpha-fetoprotein levels after 3 months of treatment(HR=2.412;95%CI,1.360–4.279;P=0.003)were independent risk factors for PFS in all patients.Conclusions:ICI-based therapy in patients with CHB-related HCC and concurrent MASLD resulted in poorer efficacy and shorter PFS compared to patients with CHB-related HCC alone.

The Effect of Blood Lipid Profiles on Chronic Kidney Disease in a Prospective Cohort:Based on a Regression Discontinuity Design

Objective Previous studies on the association between lipid profiles and chronic kidney disease(CKD)have yielded inconsistent results and no defined thresholds for blood lipids.Methods A prospective cohort study including 32,351 subjects who completed baseline and follow-up surveys over 5 years was conducted.Restricted cubic splines and Cox models were used to examine the association between the lipid profiles and CKD.A regression discontinuity design was used to determine the cutoff value of lipid profiles that was significantly associated with increased the risk of CKD.Results Over a median follow-up time of 2.2(0.5,4.2)years,648(2.00%)subjects developed CKD.The lipid profiles that were significantly and linearly related to CKD included total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),TC/HDL-C,and TG/HDL-C,whereas lowdensity lipoprotein cholesterol(LDL-C)and LDL-C/HDL-C were nonlinearly correlated with CKD.TC,TG,TC/HDL-C,and TG/HDL-C showed an upward jump at the cutoff value,increasing the risk of CKD by 0.90%,1.50%,2.30%,and 1.60%,respectively,whereas HDL-C showed a downward jump at the cutoff value,reducing this risk by 1.0%.Female and participants with dyslipidemia had a higher risk of CKD,while the cutoff values for the different characteristics of the population were different.Conclusion There was a significant association between lipid profiles and CKD in a prospective cohort from Northwest China,while TG,TC/HDL-C,and TG/HDL-C showed a stronger risk association.The specific cutoff values of lipid profiles may provide a clinical reference for screening or diagnosing CKD risk.

Occult Adrenal Insufficiency in Patients with Chronic Renal Disease

Background: Addison’s disease is a rare disorder of the adrenal cortex that leads to inadequate production of cortisol initially followed by aldosterone and androgens. Its manifestations are usually slow and non-specific with potential for life-threatening adrenal crisis following hypermetabolic demands (infection, trauma, surgery). Patients: Over the past 10 years, 19 CRD-patients were diagnosed with occult PAI in our center. Results: Unprovoked hypotension was the most common manifestations of occult PAI and was the unmasking event in 11 (58%). It was without significant cardiac and/or severe systemic sepsis and was refractory to isotonic saline infusions. Equal number of the remaining patients (n = 2) presented with persistent and inexplicable electrolytes abnormalities viz. 1) hyponatremia despite restricted oral fluid intake, lack of dehydration and massive fluid overload, as well as 2) hyperkalemia despite potassium-restricted diet, hyperkalemic drugs and adequate therapy with Furosemide and low-potassium dialysis-baths. On the other hand, similar proportions presented with unprovoked 3) progressive weight loss, decrease appetite and cachexia as well as 4) frequent hypoglycemic attacks. All patients were treated and were medically stable after 29 (2 - 60) months of follow up. Autoantibodies to 21-hydroxylase enzyme were positive in 16 (90%). At diagnosis, and subsequent follow up, only 7 patients (37%) had multi-endocrine dysfunction of whom 2 with type 1 and 5 with type 2. Conclusion: High index of suspicion should be exerted in diagnosis of PAI in patients with CRD, since its clinical picture is similar to CRD manifestations and complications. In those patients, confirmatory tests and specific management can save their lives. .

Role of diaphragmatic ultrasound in patients with acute exacerbation of chronic obstructive pulmonary disease

Assessing diaphragm function status is vital for diagnosing and treating acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Diaphrag-matic ultrasound has become increasingly important due to its non-invasive nature,absence of radiation exposure,widespread availability,prompt results,high accuracy,and repeatability at the bedside.The diaphragm is a crucial respiratory muscle.Decline or dysfunction of the diaphragm can lead to dyspnea and even respiratory failure in AECOPD patients.In this editorial,we comment on an article,retrospectively analyzed ninety-four acute exacerbations of chronic obstructive pulmonary disease patients who received mechanical ventilation from January 2022 to December 2023.The study found that the diaphragm thickening fraction,an index from diaphragm ultrasound,can better predict the outcome of non-invasive ventilation in patients with AECOPD.The value of non-invasive ventilation in treating respiratory failure caused by AECOPD has been widely acknowledged.Diaphragmatic dysfunction diagnosed with ultrasound is asso-ciated with prolonged mechanical ventilation and weaning times and higher mortality.

Chest CT quantitative parameters in patients with acute exacerbation of chronic obstructive pulmonary disease:Correlations with blood eosinophil level

Objective To observe the correlations of chest CT quantitative parameters in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)with blood eosinophil(EOS)level.Methods Chest CT data of 162 AECOPD patients with elevated eosinophils were retrospectively analyzed.The patients were divided into low EOS group(n=105)and high EOS group(n=57)according to the absolute counting of blood EOS.The quantitative CT parameters,including the number of whole lung bronchi and the volume of blood vessels,low-attenuation area percentage(LAA%)of whole lung,of left/right lung and each lobe of lung,as well as the luminal diameter(LD),wall thickness(WT),wall area(WA)and WA percentage of total bronchial cross-section(WA%)of grade 3 to 8 bronchi were compared between groups.Spearman correlations were performed to analyze the correlations of quantitative CT parameters with blood EOS level.Results LAA%of the whole lung,of the left/right lung and each lobe of lung,as well as of the upper lobe of right lung LD grade 4,middle lobe of right lung WT grade 5,upper lobe of right lung WA grade 4,middle lobe of right lung WA grade 5 and lower lobe of left lung WA grade 3 in low EOS group were all higher than those in high EOS group(all P<0.05).Except for the upper lobe of right lung LD grade 4,the above quantitative CT indexes being significant different between groups were all weakly and negatively correlated with blood EOS level(r=-0.335 to-0.164,all P<0.05).Conclusion Chest CT quantitative parameters of AECOPD patients were correlated with blood EOS level,among which LAA%,a part of WT and WA were all weakly negatively correlated with blood EOS level.

Renin-angiotensin system inhibitors prescriptions in Chinese hospitalized chronic kidney disease patients

BACKGROUND Many guidelines have recommended renin-angiotensin system inhibitors(RASI)as the first-line treatment for patients with chronic kidney disease(CKD).We studied RASI prescription trends from 2010 to 2019,and analyzed the characteristics associated with RASI prescription in Chinese hospitalized CKD patients.AIM To study the prescription of renin angiotensin system inhibitors in hospitalized patients with CKD in China.METHODS It was retrospectively,cross-sectional reviewed RASI prescriptions in hospitalized CKD patients in China from 2010 to 2019.RASI prescribing trends were analyzed from 2010 to 2019,and bivariate and multivariate logistic regression analyses were conducted to identify characteristics associated with RASI prescription.RESULTS A total of 35090 CKD patients were included,with 10043(28.6%)RASI prescriptions.Among these patients,18919(53.9%)met the criteria for RASI treatments based on the 2012 kidney disease:Improving global outcomes guidelines.Of these,7246(38.3%)patients received RASI prescriptions.RASI prescriptions showed an initial rapid increase from 2011 to 2012,reached its peak around 2015 and 2016,and then exhibited a subsequent slight decreasing trend.Both bivariate and multivariate analyses showed that several characteristics,including the male gender,age less than 60-year-old,nephrology department admission,lower CKD stage,history of hypertension or diabetes,proteinuria,glomerulonephritis as the CKD etiology,and non-acute kidney injury were associated with RASI prescriptions.CONCLUSION The frequency of RASI prescriptions showed an initial increase but a slight decreasing trend in more recent years.CKD patients with certain characteristics such as elderly age,advanced disease stage,surgery department admission,or acute kidney injury were less likely to receive RASI prescriptions.In the application of RASI in hospitalized CKD patients is insufficient.The actual clinical practice needs to be improved.The development of related research is helpful to guide the correct choice of clinical treatment strategy.
