Alcohol intolerance and myalgic encephalomyelitis/chronic fatigue

BACKGROUND The literature is mixed about the occurrence of alcohol intolerance among patients with myalgic encephalomyelitis/chronic fatigue syndrome(ME/CFS).Surveys that asked respondents with ME/CFS whether they experienced alcohol intolerance within a recent time frame might produce inaccurate results because respondents may indicate that the symptom was not present if they avoid alcohol due to alcohol intolerance.AIM To overcome this methodologic problem,participants in the current study were asked whether they have avoided alcohol in the past 6 mo,and if they had,how severe their alcohol intolerance would be if they were to drink alcohol.METHODS The instrument used was a validated scale called the DePaul symptom questionnaire.Independent t-tests were performed among the alcohol intolerant or not alcohol intolerant group.The alcohol intolerant group had 208 participants,and the not alcohol intolerant group had 96 participants.RESULTS Using specially designed questions to properly identify those with alcohol intolerance,those who experienced alcohol intolerance vs those who did not experience alcohol intolerance experienced more frequent/severe symptoms and domains.In addition,using a multiple regression analysis,the orthostatic intolerance symptom domain was related to alcohol intolerance.CONCLUSION The findings from the current study indicated that those with ME/CFS are more likely to experience alcohol intolerance.In addition,those with this symptom have more overall symptoms than those without alcohol intolerance.

An Etiological Model for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Kindling might represent a heuristic model for understanding the etiology of Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS). Kindling occurs when an organism is exposed repeatedly to an initially sub-threshold stimulus re-sulting in hypersensitivity and spontaneous seizure-like activity. Among patients with ME/CFS, chronically repeated low-intensity stimulation due to an infectious illness might cause kindling of the limbic-hypothalamic-pituitary axis. Kindling might also occur by high-intensity stimulation (e.g., brain trauma) of the limbic-hypothalamic-pituitary axis. Once this system is charged or kindled, it can sustain a high level of arousal with little or no external stimulus and eventually this could lead to hypocortisolism. Seizure activity may spread to adjacent structures of the limbic-hypothalamic-pituitary axis in the brain, which might be responsible for the varied symptoms that occur among patients with ME/CFS. In addition, kindling may also be responsible for high levels of oxidative stress, which has been found in patients with ME/CFS.

Induced pluripotent stem cells as suitable sensors for fibromyalgia and myalgic encephalomyelitis/chronic fatigue syndrome

BACKGROUND Fibromyalgia(FM)and myalgic encephalomyelitis/chronic fatigue syndrome(ME/CFS)are devastating metabolic neuroimmune diseases that are difficult to diagnose because of the presence of numerous symptoms and a lack of specific biomarkers.Despite patient heterogeneity linked to patient subgroups and variation in disease severity,anomalies are found in the blood and plasma of these patients when compared with healthy control groups.The seeming specificity of these“plasma factors”,as recently reported by Ron Davis and his group at Stanford University,CA,United States,and observations by our group,have led to the proposal that induced pluripotent stem cells(iPSCs)may be used as metabolic sensors for FM and ME/CFS,a hypothesis that is the basis for this indepth review.AIM To identify metabolic signatures in FM and/or ME/CFS supporting the existence of disease-associated plasma factors to be sensed by iPSCs.METHODS A PRISMA(Preferred Reported Items for Systematic Reviews and Meta-analysis)-based systematic review of the literature was used to select original studies evaluating the metabolite profiles of FM and ME/CFS body fluids.The MeSH terms“metabolomic”or“metabolites”in combination with FM and ME/CFS disease terms were screened against the PubMed database.Only original studies applying omics technologies,published in English,were included.The data obtained were tabulated according to the disease and type of body fluid analyzed.Coincidences across studies were searched and P-values reported by the original studies were gathered to document significant differences found in the disease groups.RESULTS Eighteen previous studies show that some metabolites are commonly altered in ME/CFS and FM body fluids.In vitro cell-based assays have the potential to be developed as screening platforms,providing evidence for the existence of factors in patient body fluids capable of altering morphology,differentiation state and/or growth patterns.Moreover,they can be further developed using approaches aimed at blocking or reversing the effects of specific plasma/serum factors seen in patients.The documented high sensitivity and effective responses of iPSCs to environmental cues suggests that these pluripotent cells could form robust,reproducible reporter systems of metabolic diseases,including ME/CFS and FM.Furthermore,culturing iPSCs,or their mesenchymal stem cell counterparts,in patient-conditioned medium may provide valuable information to predict individual outcomes to stem-cell therapy in the context of precision medicine studies.CONCLUSION This opinion review explains our hypothesis that iPSCs could be developed as a screening platform to provide evidence of a metabolic imbalance in FM and ME/CFS.

Fasudil-modified macrophages reduce inflammation and regulate the immune response in experimental autoimmune encephalomyelitis

Multiple sclerosis is characterized by demyelination and neuronal loss caused by inflammatory cell activation and infiltration into the central nervous system.Macrophage polarization plays an important role in the pathogenesis of experimental autoimmune encephalomyelitis,a traditional experimental model of multiple sclerosis.This study investigated the effect of Fasudil on macrophages and examined the therapeutic potential of Fasudil-modified macrophages in experimental autoimmune encephalomyelitis.We found that Fasudil induced the conversion of macrophages from the pro-inflammatory M1 type to the anti-inflammatory M2 type,as shown by reduced expression of inducible nitric oxide synthase/nitric oxide,interleukin-12,and CD16/32 and increased expression of arginase-1,interleukin-10,CD14,and CD206,which was linked to inhibition of Rho kinase activity,decreased expression of toll-like receptors,nuclear factor-κB,and components of the mitogen-activated protein kinase signaling pathway,and generation of the pro-inflammatory cytokines tumor necrosis factor-α,interleukin-1β,and interleukin-6.Crucially,Fasudil-modified macrophages effectively decreased the impact of experimental autoimmune encephalomyelitis,resulting in later onset of disease,lower symptom scores,less weight loss,and reduced demyelination compared with unmodified macrophages.In addition,Fasudil-modified macrophages decreased interleukin-17 expression on CD4^(+)T cells and CD16/32,inducible nitric oxide synthase,and interleukin-12 expression on F4/80^(+)macrophages,as well as increasing interleukin-10 expression on CD4^(+)T cells and arginase-1,CD206,and interleukin-10 expression on F4/80^(+)macrophages,which improved immune regulation and reduced inflammation.These findings suggest that Fasudil-modified macrophages may help treat experimental autoimmune encephalomyelitis by inducing M2 macrophage polarization and inhibiting the inflammatory response,thereby providing new insight into cell immunotherapy for multiple sclerosis.

Posttreatment Lyme disease syndrome and myalgic encephalomyelitis/chronic fatigue syndrome:A systematic review and comparison of pathogenesis

Lyme disease is the most common vector-borne illness in the United States and has been causing significant morbidity since its discovery in 1977.It is well-documented that about 10%of patients properly treated with antibiotics never fully recover,but instead go on to develop a chronic illness dubbed,posttreatment Lyme disease syndrome(PTLDS)characterized by severe fatigue,cognitive slowing,chronic pain,and sleep difficulties.This review includes 18 studies that detail the symptoms of patients with PTLDS and uses qualitative analysis to compare them to myalgic encephalitis/chronic fatigue syndrome(ME/CFS),a strikingly similar syndrome.In the majority of the PTLDS studies,at least four of the six major symptoms of ME/CFS were also noted,including substantial impairment in activity level and fatigue for more than 6 months,post-exertional malaise,and unrefreshing sleep.In one of the included PTLDS articles,26 of the 29 ME/CFS symptoms were noted.This study adds to the expanding literature on the post-active phase of infection syndromes,which suggests that chronic illnesses such as PTLDS and ME/CFS have similar pathogenesis despite different infectious origins.

Emodin attenuates inflammation and demyelination in experimental autoimmune encephalomyelitis

Emodin,a substance extracted from herbs such as rhubarb,has a protective effect on the central nervous system.However,the potential therapeutic effect of emodin in the context of multiple sclerosis remains unknown.In this study,a rat model of experimental autoimmune encephalomyelitis was established by immune induction to simulate multiple sclerosis,and the rats were intraperitoneally injected with emodin(20 mg/kg/d)from the day of immune induction until they were sacrificed.In this model,the nucleotide-binding domain-like receptor family pyrin domain containing 3(NLRP3)inflammasome and the microglia exacerbated neuroinflammation,playing an important role in the development of multiple sclerosis.In addition,silent information regulator of transcription 1(SIRT1)/peroxisome proliferator-activated receptor-alpha coactivator(PGC-1α)was found to inhibit activation of the NLRP3 inflammasome,and SIRT1 activation reduced disease severity in experimental autoimmune encephalomyelitis.Furthermore,treatment with emodin decreased body weight loss and neurobehavioral deficits,alleviated inflammatory cell infiltration and demyelination,reduced the expression of inflammatory cytokines,inhibited microglial aggregation and activation,decreased the levels of NLRP3 signaling pathway molecules,and increased the expression of SIRT1 and PGC-1α.These findings suggest that emodin improves the symptoms of experimental autoimmune encephalomyelitis,possibly through regulating the SIRT1/PGC-1α/NLRP3 signaling pathway and inhibiting microglial inflammation.These findings provide experimental evidence for treatment of multiple sclerosis with emodin,enlarging the scope of clinical application for emodin.

Role of mitochondria, oxidative stress and the response to antioxidants in myalgic encephalomyelitis/chronic fatigue syndrome: A possible approach to SARS-CoV-2 ’long-haulers’?

A significant number of SARS-CoV-2 (COVID-19) pandemic patients have developed chronic symptoms lasting weeks or months which are very similar to those described for myalgic encephalomyelitis/chronic fatigue syndrome. This study reviews the current literature and understanding of the role that mitochondria, oxidative stress and antioxidants may play in the understanding of the pathophysiology and treatment of chronic fatigue. It describes what is known about the dysfunctional pathways which can develop in mitochondria and their relationship to chronic fatigue. It also reviews what is known about oxidative stress and how this can be related to the pathophysiology of fatigue, as well as examining the potential for specific therapy directed at mitochondria for the treatment of chronic fatigue in the form of antioxidants. This study identifies areas which require urgent, further research in order to fully elucidate the clinical and therapeutic potential of these approaches.

The Effect of Curcumin on Patients with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis: An Open Label Study

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), recently renamed as systemic exertion intolerance disease (SEID), is a chronic and often disabling disease. Although the exact pathophysiological mechanism of ME/CFS is unknown, immunological abnormalities may play an important role. Curcumin is a herb with powerful anti-oxidative, and anti-inflammatory properties. Therefore, we hypothesized that curcumin has favorable effects on symptomatology in ME/CFS patients. In total 52 patients participated, nine stopped the use of curcumin because of side effects. All remaining patients (n = 43) met the criteria for CFS;72% met the criteria for ME. Before and 8 weeks after the use of curcumin complexed with phosphatidyl choline, 500 mg bid, the CDC inventory for assessment of Chronic Fatigue Syndrome was filled in. The CDC questions (n = 19) were scored and divided into 2 parts: the first being specific for CFS complaints (n = 9), the second being scores of less specific symptoms (n = 10);denoted as CDC rest score. Results showed that 8 weeks curcumin use significantly decreased the CFS related symptom scores, but not the CDC rest scores. Analyzing the data separately for ME and CFS patients, the same significance for the CFS symptom scores was present. Conclusion: in this open-labeled study, 8 weeks curcumin use in a phosphatidyl choline complex reduced ME/CFS symptomatology. Therefore, a randomized placebo controlled study is warranted to assess its efficacy in ME/CFS patients.

Quantification of the Beneficial Effects of Compression Stockings on Symptoms of Exercise and Orthostatic Intolerance in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis Patients

Chronic fatigue syndrome and myalgic encephalomyelitis (CFS/ME) are, amongst others, characterized by exercise intolerance, pain, post exertional malaise and orthostatic intolerance. It has been shown in venous disease and sport participation that compression stockings may improve exercise performance and reduce post exercise muscle soreness. Moreover, its use is advocated in orthostatic hypotension. Therefore, it was hypothesized that compression stockings may reduce symptomatology in CFS/ME patients. Methods: 100 patients used compression stockings class II for minimally 3 weeks and thereafter filled in a questionnaire, based on the Rand 36 physical activity questions (n = 9), whether compression stockings changed perceived symptoms or not. Moreover, 7 questions referring to prolonged standing and sitting, to recovery post exercise, muscle pain during or immediately post exercise, and to dizziness/light-headedness during or immediately post exercise, while standing and during prolonged sitting were added. Questions were scored as 1: able to perform activity much less while wearing the stockings, 2: perform activity somewhat less, 3: no perceived change in activity, 4: perform activity slightly better, 5: able to perform activity much better while wearing the stockings. Results: In patients able to answer the question, all mean scores per activity were significantly higher than 3, being no perceived change in activity while wearing the stockings. Subgroup analysis showed that patients with orthostatic intolerance reported higher effects than patients without orthostatic intolerance. Conclusion: This pilot study suggests that compression stockings may be useful to reduce symptomatology of physical activities in CFS/ME patients, especially in patients with orthostatic intolerance. Larger prospective studies with hard endpoints are warranted.

Accurate diagnosis of myalgic encephalomyelitis and chronic fatigue syndrome based upon objective test methods for characteristic symptoms

Although myalgic encephalomyelitis(ME) and chronic fatigue syndrome(CFS) are considered to be synonymous,the definitional criteria for ME and CFS define two distinct,partially overlapping,clinical entities.ME,whether defined by the original criteria or by the recently proposed criteria,is not equivalent to CFS,let alone a severe variant of incapacitating chronic fatigue.Distinctive features of ME are:muscle weaknessand easy muscle fatigability,cognitive impairment,circulatory deficits,a marked variability of the symptoms in presence and severity,but above all,post-exertional "malaise":a(delayed) prolonged aggravation of symptoms after a minor exertion.In contrast,CFS is primarily defined by(unexplained) chronic fatigue,which should be accompanied by four out of a list of 8 symptoms,e.g.,headaches.Due to the subjective nature of several symptoms of ME and CFS,researchers and clinicians have questioned the physiological origin of these symptoms and qualified ME and CFS as functional somatic syndromes.However,various characteristic symptoms,e.g.,post-exertional "malaise" and muscle weakness,can be assessed objectively using wellaccepted methods,e.g.,cardiopulmonary exercise tests and cognitive tests.The objective measures acquired by these methods should be used to accurately diagnose patients,to evaluate the severity and impact of the illness objectively and to assess the positive and negative effects of proposed therapies impartially.

Decreased Expression of TRPM3 and mAChRM3 in the Small Intestine in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis

Introduction: Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is often associated with gastrointestinal disturbance and inflammatory markers;however, there have been no histological studies performed in the small intestine from CFS/ME patients. The aim of this investigation was to assess the expression of certain inflammatory markers and inflammatory receptors, namely transient receptor potential melastin 3 (TRPM3) ion channels and muscarinic acetylcholine M3 (mAChRM3) receptors, in small intestinal tissues in a case controlled study comprising a CFS/ME patient and a healthy non-fatigued control. Method: Immunohistochemistry was performed on a small intestinal biopsy from a CFS/ME patient (age = 50;female) with self-reported symptoms of gastrointestinal disturbance and a non-fatigued control (NFC), (age = 28;female). Semi-quantitative analysis of expression was undertaken for interferon-gamma (IFNy), interleukin-1 alpha (IL-1α), tumour necrosis factor-alpha (TNFα), TRPM3 ion channels and mAChRM3 acetylcholine receptors. Results: There was significantly decreased expression of TRPM3 in the CFS/ME patient (35% ±9%) and a significant decrease in mAChRM3 in the CFS/ME patient (54% ±9%). There was no difference in IL-1α between CFS/ME patient and NFC, however;there was an increase in IFNy (13% ±6%) in the CFS/ME patient compared to NFC. There was a difference observed in TNFα in CFS/ME compared to NFC. Conclusion: Differences were noted in the expression of specific TRP ion channels and cholinergic receptors in CFS/ME compared with NFC, with CFS/ME demonstrating decreased TRPM3 and mAChRM3. Further, IFNy was increased, and TNFα decreased, in the small intestine of the CFS/ME patient with reported gastrointestinal disturbance.

Epidemiological and Diagnostic Profile of Patients with Chronic Hepatitis B Virus from 2017 to 2021 in Parakou, Republic of Benin

Introduction: Viral hepatitis B is a public health problem worldwide. The objective of this study was to determine the epidemiological and diagnostic profile of chronic carriers of hepatitis B virus seen for gastroenterology consultations in Parakou, Republic of Benin. Patients and Methods: This was a cross-sectional and descriptive study with retrospective data collection. Patients seen for gastroenterology consultations from January 1, 2017 to June 30, 2021 at the Regional Teaching Hospital of Borgou/Alibori (CHUD-B/A) and having been diagnosed as chronic carriers of hepatitis B virus were included. A minimum initial assessment was required to be included. The minimum sample size was calculated with Schwartz formula. The variable of interest was the detection of HBsAg twice and at least 6 months apart. The other variables studied were sociodemographic, clinical and paraclinical data. The data collected were analyzed using SPSS 17 software. Results: A total of 2786 patients were seen for gastroenterology consultations, including 1126 (40.4%) HBsAg-positive patients. Among them, 417 patients met the inclusion criteria and were the subject of the present study. The average age of the patients was 34.8 ± 10.5 years. Two hundred and forty-seven patients (65.7%) were male, representing a sex ratio of 1.9. The discovery of positive HBsAg status was made during systematic screening in 231 patients (55.4%). Scarifications were noted in 373 patients (89.4%). Asthenia was reported in 184 patients (44.1%). Co-infections with human immunodeficiency virus, hepatitis C and D viruses were 0% (0 in 92), 2.8% (4 in 146) and 14.3% (2 in 146), respectively. During the initial assessment, 274 patients (65.7%) were sero-negative for chronic HBeAg infection, 21 (5%) had clinically significant fibrosis including 16 (3.8%) at the stage of cirrhosis and 7 patients (5.4%) had hepatocellular carcinoma. Conclusion: In Parakou, chronic hepatitis B virus infection is common and affects young people with a male predominance. Asthenia is a non-specific symptom and the most reported by the patients. Around 5 out of 100 patients are seen for consultations at the stage of complication. Emphasis must be placed on early detection and subsidy for pre-therapeutic assessment.

Factors Associated with Renal Impairment in Patients on Tenofovir for Chronic Hepatitis B in Yaoundé (Cameroon)

Background: Tenofovir (TFV) is widely used to treat patients with hepatitis B virus (HBV) infection. But kidney abnormalities are the main concern using this drug. Few studies have described the renal impairment due to the TFV in chronic hepatitis B (CHB) in Sub-Saharan Africa. The objective was to evaluate factors associated with renal impairment observed in patients on TFV for CHB. Method: It was a hospital based cross sectional prospective study carried out from June 2023 to July 2023 in Yaoundé (Cameroon) and included any patient treated with TFV for CHB during at least a period of 6 months. For each participant, we collected in the medical report socio-demographic data, clinical data, baseline creatinine, treatment information (type of TFV which was Disoproxil Fumarate (TDF) or Alafenamide (TAF), duration). Then, we collected blood samples to measure serum creatinine and phosphate levels and urine dipstick analysis. Factors associated with renal impairment were assessed with the Odds Ratio. A p value of Results: A total of 60 participants were included. The median age was 44 years [36-55] and median duration of TFV therapy was 17.5 months [11.7-25.7]. The prevalence of reduced eGFR (Conclusion: Kidney function was impaired in some patients receiving TFV for CHB. It should be monitored, particularly after 36 months and for those receiving TDF prodrug.

Complex Regional Pain Syndrome: Outpatient Pain Management in the Chronic Setting: A Case Report

Background: Complex Regional Pain Syndrome (CRPS), previously known as reflex sympathetic dystrophy and causalgia, is a neuropathic pain condition that usually develops after an injury to an extremity. CRPS can be a debilitating condition with high levels of pain and reduced function. Aim: This case report aims to discuss the multimodal approach in the management of a patient who presented with ongoing poorly controlled pain secondary to CRPS from an injury that happened years prior. Case Presentation: A 45-year-old female was involved in a motor vehicle accident where her right leg was injured. She underwent several surgeries and developed CRPS that significantly reduced her mobility and quality of life. She presented to the pain clinic years after her initial injury and a multimodal regimen was started for her resulting in significantly improved function. Conclusion: CRPS can be a severely debilitating condition. While early diagnosis and management are important, ongoing management in the outpatient chronic pain setting is important in maintaining a good level of function.

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.

Clinical Study of Shentong Zhuyu Decoction Combined with Massage Therapy in the Treatment of Exertional Chronic Lumbar Muscle Strain

[Objectives]To explore the effects of Shentong Zhuyu decoction combined with massage therapy in the treatment of exertional chronic lumbar muscle strain.[Methods]Sixty-four cases of exertional chronic lumbar muscle strain were randomly divided into two groups(32 cases each group).The patients in the control group only took celecoxib capsules,and those in the treatment group additionally took Shentong Zhuyu decoction combined with massage therapy.TCM syndrome score,lumbar function,hemorrheology index and clinical effect were compared between the two groups before and after treatment.[Results]After treatment,the TCM syndrome scores of lumbar distension/dull pain,tingling-like lumbago,adverse lateral turn,body weight loss,dark purple tongue,slow or astringent pulse,and Oswestry disability index(ODI)score in the treatment group were lower than those in the control group,and the levels of plasma viscosity,red blood cell aggregation index,platelet aggregation rate(PAG)and fibrinogen(Fib)were lower than those in the control group,showing statistical significance(P<0.05).The overall clinical effect distribution of the treatment group was better than that of the control group,and the difference was statistically significant(P<0.05).[Conclusions]Shentong Zhuyu decoction combined with massage therapy can effectively relieve the symptoms of patients with lumbago and improve the lumbar mobility function and hemorrheology,with obvious therapeutic effects in the treatment of exertional chronic lumbar muscle strain.

Assessment of the triglyceride glucose index in adult patients with chronic diarrhea and constipation

BACKGROUND Accumulating evidence suggests that the gut microbiome is involved in the pathogenesis of insulin resistance(IR).However,the link between two of the most prevalent bowel disorders,chronic diarrhea and constipation,and the triglyceride glucose(TyG)index,a marker of IR,has not yet been investigated.AIM To investigate the potential association between TyG and the incidence of chronic diarrhea and constipation.METHODS This cross-sectional study enrolled 2400 participants from the National Health and Nutrition Examination Survey database from 2009-2010.TyG was used as an exposure variable,with chronic diarrhea and constipation as determined by the Bristol Stool Form Scale used as the outcome variables.A demographic investigation based on TyG quartile subgroups was performed.The application of multivariate logistic regression models and weighted generalized additive models revealed potential correlations between TyG,chronic diarrhea,and constipation.Subgroup analyses were performed to examine the stability of any potential associations.RESULTS In the chosen sample,chronic diarrhea had a prevalence of 8.00%,while chronic constipation had a prevalence of 8.04%.In multiple logistic regression,a more prominent positive association was found between TyG and chronic diarrhea,particularly in model 1(OR=1.45;95%CI:1.17-1.79,P=0.0007)and model 2(OR=1.40;95%CI:1.12-1.76,P=0.0033).No definite association was observed between the TyG levels and chronic constipation.The weighted generalized additive model findings suggested a more substantial positive association with chronic diarrhea when TyG was less than 9.63(OR=1.89;95%CI:1.05-3.41,P=0.0344),and another positive association with chronic constipation when it was greater than 8.2(OR=1.74;95%CI:1.02-2.95,P=0.0415).The results of the subgroup analyses further strengthen the extrapolation of these results to a wide range of populations.CONCLUSION Higher TyG levels were positively associated with abnormal bowel health.

Chronic venous insufficiency, could it be one of the missing pieces in the puzzle of treating pain?

Pain is a common complaint among patients seeking medical care.If left un-treated,pain can become chronic,significantly affecting patients’quality of life.An accurate diagnosis of the underlying cause of pain is crucial for effective treatment.Chronic venous insufficiency(CVI)is frequently overlooked by pain physicians.Moreover,many pain physicians lack sufficient knowledge about CVI.CVI is a common condition resulting from malfunctioning or damaged valves in lower limb veins.Symptoms of CVI,ranging from mild to severe,include pain,heaviness,fatigue,itching,swelling,skin color changes,and ulcers in the lower limbs.Recently,it has become more widely known that these symptoms can be attributed to CVI.Even slight or mild CVI can cause related symptoms.Pain physicians primarily consider neuromusculoskeletal disorders when assessing patients with leg pain,and often neglect the possibility of CVI.In clinical practice,when pain physicians encounter patients with unresolved leg pain,they must assess whether the patients exhibit symptoms of CVI and conduct tests to differ-entiate CVI from other potential causes.

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.

Assessment of the Level of Knowledge about Chronic Renal Failure in 271 Hypertensive Patients in Brazzaville

Background and Objectives: Chronic kidney disease (CKD) is now a global public health problem. In low- and middle-income countries such as the Congo, access to dialysis is low and inequitable. The prevention of CKD involves raising awareness among patients at risk, such as those suffering from arterial hypertension (AH), by improving their knowledge of CKD. The objectives of our work were to determine the level of knowledge about CKD among hypertensive patients and to identify the factors associated with a low level of knowledge. Methodology: We conducted a 3-month descriptive and analytical cross-sectional study from 1 August to 30 October 2023 in 3 large public hospitals in Brazzaville (capital of the Republic of Congo). We included: hypertensive patients aged 18 and over who had freely consented to participate in our study and were able to answer the questions on the survey form. Patients with known hypertension who had been followed for less than 3 years and those with known chronic renal failure were not included. Results: The mean age was 58.4 ± 14.4 years (29 - 88 years). There were 121 men and 150 women (sex ratio = 0.8). All the patients were educated;37.2% with a higher level of education and 13.6% with primary education. 24 patients (9%) had a good level of knowledge about CKD and 153 (56%) had poor knowledge. A good level of knowledge was associated with the duration of hypertension, intellectual level and the existence of associated heart disease. Conclusion: Our study reveals a significant lack of knowledge about chronic kidney disease among hypertensive patients in Brazzaville.
