Methods: Single nucleotide polymorphisms (SNPs) that exhibit a strong association with vascular dementia (VD) were identified as instrumental variables from the summary statistics of genome-wide association studies (GWAS). The primary analytical method employed was inverse variance weighting (IVW), while auxiliary analyses included the MR-Egger method, weighted median method, simple model, and weighted model. A two-way Mendelian randomization analysis was conducted to assess the causal relationship between inflammatory factors and the risk of VD, thereby identifying the key inflammatory factors involved. The MR-Egger intercept test and Cochran’s Q test were employed to assess the horizontal polymorphism and heterogeneity of instrumental variables. A sensitivity analysis was conducted by excluding one method at a time. Ultimately, based on key inflammatory factors, predictions for the prevention and treatment using traditional Chinese medicine were made, along with the screening of homologous herbal remedies. Results: Based on the results of the forward MR, the probability of developing VD was elevated when the inflammatory factors CXCL10 and CXCL5 were expressed at higher levels, whereas the probability of developing VD decreased as the expression levels of IL-13 and IL-20RA increased. These findings were supported by the assessment of pleiotropy, heterogeneity, and sensitivity. The results of the reverse MR analysis showed that there was no causal relationship between VD, as an exposure dataset, and these four inflammatory factors. According to the key inflammatory factors, 37 Chinese herbal medicines such as Siraitia grosvenorii were selected. Their characteristics including four natures, five flavors, channel tropism and treatment efficiency were cold, warm, neutral, pungent, sweet, bitter, lung meridian, spleen meridian, liver meridian, kidney meridian and clearing heat. Among them, Siraitia grosvenorii, Poria with hostwood, Perilla frutescens, and Radix Platycodi were all medicine and food homologous Chinese herbal medicines. Conclusions: The increase of CXCL10 and CXCL5 expression levels can increase the risk of VD, and the increase of IL-13 and IL-20 RA expression levels can reduce the risk of VD. Siraitia grosvenorii and other Chinese herbal medicines might be potential sources of therapeutic drugs for the treatment of VD. Medicine and food homologous Chinese herbal medicines, such as Siraitia grosvenorii, Poria with hostwood, Perilla frutescens, and Radix Platycodi, may help the elderly population with corresponding Traditional Chinese Medicine (TCM) constitutions to prevent VD.展开更多

Pregnancy increases cardiovascular risks, particularly through the development of gestational hypertension and preeclampsia, requiring early screening and close monitoring to prevent adverse outcomes. Objectives: This study aimed to evaluate the frequency of cardiovascular risk factors in pregnant women in Senegal and identify associated socio-behavioral and economic determinants. Methodology: A descriptive, analytical cross-sectional study with prospective data collection was conducted over three months (April 10 to July 10, 2023). The study included pregnant women aged 15 and older from three public hospital maternity wards in Senegal. We studied sociodemographic aspects, cardiovascular risk factors, and collected information on previous and current pregnancies, including the number of pregnancies, parity, miscarriages, the number of prenatal consultations, and the number of fetuses. Written consent was obtained. A p-value ≤ 0.05 was considered statistically significant. Results: A total of 222 pregnant women were enrolled, representing 28% of prenatal consultations. The average age was 29.18 years (range 15 - 47). Most participants (90%) lived in Dakar suburbs, 74.20% had no medical coverage, 84% worked in the informal sector (p = 0.043), and 18% had no education. Among them, 30.63% were in their first pregnancy, 34% were nulliparous, and 3.15% were grand multiparous. The average number of prenatal visits was 3.5, with about 40% having more than four visits. Risk factors included hypertension (17%), more prevalent in women over 30 (p = 0.043), diabetes (4%), and smoking (2%). Conclusion: The study highlights critical prenatal health needs and socio-economic challenges faced by pregnant women, emphasizing the need for targeted strategies to improve healthcare access and health education.展开更多

The aim of the study was to determine the frequencies of cardiovascular risk factors (CVRF) and factors associated with hypertension among hotel workers in the city of Bohicon. Methods: This was a descriptive and analytical cross-sectional study conducted in the period from December 2018 to January 2019. The variables studied were sociodemographic, occupational, anthropometric and behavioral. Participant recruitment was exhaustive. A standardized questionnaire inspired by the STEPS-WHO questionnaire was used for data collection. After the descriptive analysis, a bivariate analysis was performed using Pearson’s Chi-square test or Fisher’s test at the 5% threshold. Results: A total of 101 workers, 53 (52.47%) of them male, participated in the study. The mean age was 30.60 ± 8.20 years, with extremes of 18 and 55 years. The frequencies of the main risk factors were: 68.32% sitting position > 6 hours/day;38.61% shift work;21.78% high psychological demand, 82.18% low decision latitude, 24.75% low social support, 21.78% occupational stress;7 (6.93%) harmful alcohol consumption;6.93% tobacco consumption;48.51% insufficient physical activity;98.02% insufficient fruit and vegetable consumption;59.41% overweight;14.85% HTA. Factors associated with hypertension were: sex, age and marital status. Conclusion: Occupational factors need to be taken into account when assessing CVRFs. NCD control programs are needed in all sectors of activity. A larger study is needed in the hotel sector.展开更多

The aim of this study was to assess the prevalence of risk factors and cardiovascular diseases according to residents in town of Bougouni and its rural area (southern Mali). Methods: This was a retrospective descriptive study from February 2019 to March 2024. All patients who visited the “CENTRE MEDICAL DE BOUGOUNI” clinic with known or suspected heart disease during the study period were included. Data were collected from medical records. Incomplete or unusable records were excluded. Data were processed using SPS version 22 software. Results: we included 452 patients with an average age of 50 ± 19 years. High blood pression has been found in 42.70% of cases, with higher prevalence in urban areas (47.01%) than in rural areas (41.50%). Diabetes and smoking were found respectively 5.31% and 8.19% in our population. The prevalence of diabetes was higher in urban areas (5.97%) than rural area (5.35%). smoking prevalence was higher in rural areas (8.49%) than urban areas (6.72%). Alcoholism was found in 2.21% of cases with a little difference between rural area (2.24%) and urban area (2.20%). 31.63% of our patients had no cardiovascular factor.

Diagnosis of idiopathic dilated cardiomyopathy was found in 23.45% of cases with higher prevalence in rural areas (28.30%) than urban areas (13.43%). Ischaemic heart disease accounted for 9.29% of cases with a higher prevalence in rural areas (10.38%) than in urban areas (6.71%). PPCMs accounted for 5.98% of cases, with a slight increase in urban areas (6.66%) compared with rural areas (5.68%). Rheumatic valvulopathy accounted for 2.21% of cases;2.84% in rural areas and 0.74% in urban areas. Other valvular diseases accounted for 3.76% of cases;4.73% in rural areas and 1.48% in urban areas. Right heart diseases accounted for 3.98% of cases and stroke for 1.77%. Conclusion: The prevalence of cardiovascular risk factors and heart diseases is high in the rural and urban population of the town of Bougouni and its surroundings (Mali). Excepted smoking, the prevalence of other CV risk factors is higher in urban areas, whereas the prevalence of idiopathic dilated cardiomyopathy and ischemic heart disease is higher in rural areas. These data could serve as a basis for developing tailored preventive strategies, depending on the place of residence.展开更多

More than 50% of Nyeri County Referral Hospital (NCRH) admissions result from non-communicable diseases (NCDs) and over 55% of hospital deaths are attributable to NCDs. In Kenya, Nyeri County has the highest prevalence of diabetes mellitus compared to other counties. This study therefore sought to assess the prevalence of microvascular complications and the associated risk factors among patients attending Nyeri County Referral Hospital in Kenya. A hospital-based cross-sectional study was conducted on 314 DM patients on follow-up at NCRH from August 2022 to October 2022. Data were analyzed using STATA version 17. Univariate and multivariate logistic regression analyses are used to determine the risk factors associated with Microvascular complications of DM. Among the 314 participants with DM, 58% were females. The overall prevalence of Microvascular complications (MVCs) is 36.62%. Diabetic peripheral neuropathy was the most frequent complication (27.4%). Inadequate physical exercise was a risk factor for all MVCs. Age, marital status, and level of education were risk factors for neuropathy while smoking and alcohol intake were risk factors for nephropathy. Non-smokers were 98% less likely to have nephropathy (OR = 0.024;95% CI 0.003 - 0.145). The odds of those who exercise once weekly getting retinopathic complications reduced by 83% (OR = 0.18, 95% CI 0.049 - 0.398) compared to those who exercise daily. The findings highlight the implication of lifestyle factors in the development of MVCs among DM patients. Therefore, benefits of microvascular complications prevention should thus be factored into the management of patients with diabetes mellitus.展开更多

Material and Methods: This was a descriptive cross-sectional study conducted at the Donka University Hospital from June 1 to July 4, 2020 on subjects received for COVID-19 screening. Results: The prevalence of diabetes in patients suspected of COVID-19 was 7.8% comprising 1.2% of known diabetics and 6.8% of new cases. The prevalence of active smoking was 14.0%. That of sedentary lifestyle and obesity were 10.6% and 17.2% respectively. We found a prevalence of hypertension estimated at 45%, it was unknown in 76.47% of cases. In this series, 33.2% of patients had a high and very high cardiovascular risk (WHO scores). Conclusion: This study reveals a fairly high prevalence of diabetes and other cardiovascular risk factors in the population of people suspected of COVID-19. This observation should lead to the implementation of effective strategies for the prevention of non-communicable diseases in Guinea.展开更多

文摘After brain damage,regenerative angiogenesis and neurogenesis have been shown to occur simultaneously in mammals,suggesting a close link between these processes.However,the mechanisms by which these processes interact are not well understood.In this work,we aimed to study the correlation between angiogenesis and neurogenesis after a telencephalic stab wound injury.To this end,we used zebrafish as a relevant model of neuroplasticity and brain repair mechanisms.First,using the Tg(fli1:EGFP×mpeg1.1:mCherry)zebrafish line,which enables visualization of blood vessels and microglia respectively,we analyzed regenerative angiogenesis from 1 to 21 days post-lesion.In parallel,we monitored brain cell proliferation in neurogenic niches localized in the ventricular zone by using immunohistochemistry.We found that after brain damage,the blood vessel area and width as well as expression of the fli1 transgene and vascular endothelial growth factor(vegfaa and vegfbb)were increased.At the same time,neural stem cell proliferation was also increased,peaking between 3 and 5 days post-lesion in a manner similar to angiogenesis,along with the recruitment of microglia.Then,through pharmacological manipulation by injecting an anti-angiogenic drug(Tivozanib)or Vegf at the lesion site,we demonstrated that blocking or activating Vegf signaling modulated both angiogenic and neurogenic processes,as well as microglial recruitment.Finally,we showed that inhibition of microglia by clodronate-containing liposome injection or dexamethasone treatment impairs regenerative neurogenesis,as previously described,as well as injury-induced angiogenesis.In conclusion,we have described regenerative angiogenesis in zebrafish for the first time and have highlighted the role of inflammation in this process.In addition,we have shown that both angiogenesis and neurogenesis are involved in brain repair and that microglia and inflammation-dependent mechanisms activated by Vegf signaling are important contributors to these processes.This study paves the way for a better understanding of the effect of Vegf on microglia and for studies aimed at promoting angiogenesis to improve brain plasticity after brain injury.
文摘BACKGROUND Despite significant advancements in the medical treatment of primary hepato-cellular carcinoma(PHC)in recent years,enhancing therapeutic effects and im-proving prognosis remain substantial challenges worldwide.AIM To investigate the expression levels of serum vascular endothelial growth factor(VEGF)and interleukin(IL)-17 in patients with PHC and evaluate their diagnostic value while exploring their relationship with patients’clinical characteristics.METHODS The study included 50 patients with confirmed PHC who visited Wuhan Han-yang Hospital from January 2021 to January 2022,and 50 healthy individuals from the same period served as the control group.Serum VEGF and IL-17 levels in both groups were measured by Enzyme-Linked Immunosorbent Assay,and their diagnostic value was assessed using receiver operating characteristic(ROC)curves.Pearson correlation analysis was performed to examine the relationship between serum VEGF and IL-17 levels.Pathological data of the PHC patients were analyzed to determine the relationship between serum VEGF and IL-17 levels and pathological characteristics.RESULTS Serum VEGF and IL-17 levels were significantly higher in the study group com-pared to the control group(P<0.05).No significant association was observed between serum VEGF and IL-17 levels and gender,age,combined cirrhosis,tumor diameter,or degree of differentiation(P>0.05).However,there was a significant relationship between clinical TNM stage,tumor metastasis,and serum VEGF and IL-17 levels(P<0.05).Correlation analysis revealed a positive correlation between serum VEGF and IL-17(P<0.05).ROC analysis demonstrated that both serum VEGF and IL-17 had good diagnostic efficacy for PHC.CONCLUSION Serum VEGF and IL-17 levels were significantly higher in PHC patients compared to healthy individuals.Their levels were closely related to pathological features such as tumor metastasis and clinical TNM stage,and there was a significant positive correlation between VEGF and IL-17.These biomarkers may serve as valuable reference in-dicators for the early diagnosis and treatment guidance of PHC.

文摘The integrity of retinal ganglion cells is tightly associated with diabetic macular degeneration that leads to damage and death of retinal ganglion cells,affecting vision.The major clinical treatments for diabetic macular edema are anti-vascular endothelial growth factor drugs and laser photocoagulation.However,although the macular thickness can be normalized with each of these two therapies used alone,the vision does not improve in many patients.This might result from the incomplete recovery of retinal ganglion cell injury.Therefore,a prospective,non-randomized,controlled clinical trial was designed to investigate the effect of anti-vascular endothelial growth factor drugs combined with laser photocoagulation on the integrity of retinal ganglion cells in patients with diabetic macular edema and its relationship with vision recovery.In this trial,150 patients with diabetic macular edema will be equally divided into three groups according to therapeutic methods,followed by treatment with anti-vascular endothelial growth factor drugs,laser photocoagulation therapy,and their combination.All patients will be followed up for 12 months.The primary outcome measure is retinal ganglion cell-inner plexiform layer thickness at 12 months after treatment.The secondary outcome measures include retinal ganglion cell-inner plexiform layer thickness before and 1,3,6,and 9 months after treatment,retinal nerve fiber layer thickness,best-corrected visual acuity,macular area thickness,and choroidal thickness before and 1,3,6,9,and 12 months after treatment.Safety measure is the incidence of adverse events at 1,3,6,9,and 12 months after treatment.The study protocol hopes to validate the better efficacy and safety of the combined treatment in patients with diabetic macula compared with the other two monotherapies alone during the 12-month follow-up period.The trial is designed to focus on clarifying the time-effect relationship between imaging measures related to the integrity of retinal ganglion cells and best-corrected visual acuity.The trial protocol was approved by the Medical Ethics Committee of the Affiliated Hospital of Beihua University with approval No.(2023)(26)on April 25,2023,and was registered with the Chinese Clinical Trial Registry(registration number:ChiCTR2300072478,June 14,2023,protocol version:2.0).
文摘AIM:To investigate the role of connective tissue growth factor(CTGF)and vascular endothelial growth factor(VEGF)in the protein profile of the aqueous humor in patients with proliferative diabetic retinopathy(PDR)following intravitreal injection of conbercept.METHODS:This study included 72 PDR patients and 8 cataract patients as controls.PDR patients were divided into 3 groups according to the intervals of 3,5,and 7d between intravitreal conbercept(IVC,0.5 mg/0.05 mL)injection and pars plana vitrectomy(PPV)performed.Aqueous humor samples were collected before and after IVC and PPV for VEGF and CTGF levels detected with enzyme-linked immunosorbent assay(ELISA).The differential proteomics of 10 patients who underwent PPV surgery 5d after IVC and 8 normal controls was studied,Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis were performed on the data,and the protein interaction network of 23 differential proteins was studied.RESULTS:Post-IVC,VEGF levels decreased and CTGF levels increased significantly in aqueous humor,with the CTGF/VEGF ratio rising significantly at all intervals.Liquid chromatography tandem mass spectrometry(LC-MS/MS)identified differentially expressed proteins between preand post-IVC samples.GO and KEGG analyses revealed involvement in immune response,stress response,complement and coagulation cascades,ferroptosis,and PPAR signaling pathways.PPI analysis highlighted key proteins like APOA1,C3,and transferrin(TF).ELISA assay confirmed the differential expression of proteins such as HBA1,SERPINA1,COL1A1,and ACTB,with significant changes in the IVC groups.CONCLUSION:The study demonstrates that IVC effectively reduces VEGF levels while increasing CTGF levels,thereby modifying the CTGF/VEGF ratio,and IVC significantly alters the protein profile in the aqueous humor of patients with PDR.Proteomic analysis reveals that these changes are associated with critical biological pathways and protein interactions involved in immune response,stress response,and cellular metabolism.
文摘Objective: This study aims to examine the causal relationship between inflammatory factors and the probability of developing vascular dementia (VD) using Mendelian Randomization (MR) and Chinese herbal medicine prediction method, and to screen potential Chinese herbal medicines for the prevention and treatment of VD. Methods: Single nucleotide polymorphisms (SNPs) that exhibit a strong association with vascular dementia (VD) were identified as instrumental variables from the summary statistics of genome-wide association studies (GWAS). The primary analytical method employed was inverse variance weighting (IVW), while auxiliary analyses included the MR-Egger method, weighted median method, simple model, and weighted model. A two-way Mendelian randomization analysis was conducted to assess the causal relationship between inflammatory factors and the risk of VD, thereby identifying the key inflammatory factors involved. The MR-Egger intercept test and Cochran’s Q test were employed to assess the horizontal polymorphism and heterogeneity of instrumental variables. A sensitivity analysis was conducted by excluding one method at a time. Ultimately, based on key inflammatory factors, predictions for the prevention and treatment using traditional Chinese medicine were made, along with the screening of homologous herbal remedies. Results: Based on the results of the forward MR, the probability of developing VD was elevated when the inflammatory factors CXCL10 and CXCL5 were expressed at higher levels, whereas the probability of developing VD decreased as the expression levels of IL-13 and IL-20RA increased. These findings were supported by the assessment of pleiotropy, heterogeneity, and sensitivity. The results of the reverse MR analysis showed that there was no causal relationship between VD, as an exposure dataset, and these four inflammatory factors. According to the key inflammatory factors, 37 Chinese herbal medicines such as Siraitia grosvenorii were selected. Their characteristics including four natures, five flavors, channel tropism and treatment efficiency were cold, warm, neutral, pungent, sweet, bitter, lung meridian, spleen meridian, liver meridian, kidney meridian and clearing heat. Among them, Siraitia grosvenorii, Poria with hostwood, Perilla frutescens, and Radix Platycodi were all medicine and food homologous Chinese herbal medicines. Conclusions: The increase of CXCL10 and CXCL5 expression levels can increase the risk of VD, and the increase of IL-13 and IL-20 RA expression levels can reduce the risk of VD. Siraitia grosvenorii and other Chinese herbal medicines might be potential sources of therapeutic drugs for the treatment of VD. Medicine and food homologous Chinese herbal medicines, such as Siraitia grosvenorii, Poria with hostwood, Perilla frutescens, and Radix Platycodi, may help the elderly population with corresponding Traditional Chinese Medicine (TCM) constitutions to prevent VD.

文摘BACKGROUND The incidence and mortality of colorectal cancer(CRC)are among the highest in the world,and its occurrence and development are closely related to tumor neovascularization.When the balance between pigment epithelium-derived factors(PEDF)that inhibit angiogenesis and vascular endothelial growth factors(VEGF)that stimulate angiogenesis is broken,angiogenesis is out of control,resulting in tumor development.Therefore,it is very necessary to find more therapeutic targets for CRC for early intervention and later treatment.AIM To investigate the expression and significance of PEDF,VEGF,and CD31-stained microvessel density values(CD31-MVD)in normal colorectal mucosa,adenoma,and CRC.METHODS In this case-control study,we collected archived wax blocks of specimens from the Digestive Endoscopy Center and the General Surgery Department of Chengdu Second People's Hospital from April 2022 to October 2022.Fifty cases of specimen wax blocks were selected as normal intestinal mucosa confirmed by electronic colonoscopy and concurrent biopsy(normal control group),50 cases of specimen wax blocks were selected as colorectal adenoma confirmed by electronic colonoscopy and pathological biopsy(adenoma group),and 50 cases of specimen wax blocks were selected as CRC confirmed by postoperative pathological biopsy after inpatient operation of general surgery(CRC group).An immunohistochemical staining experiment was carried out to detect PEDF and VEGF expression in three groups of specimens,analyze their differences,study the relationship between the two and clinicopathological factors in CRC group,record CD31-MVD in the three groups,and analyze the correlation of PEDF,VEGF,and CD31-MVD in the colorectal adenoma group and the CRC group.The F test or adjusted F test is used to analyze measurement data statistically.Kruskal-Wallis rank sum test was used between groups for ranked data.The chi-square test,adjusted chi-square test,or Fisher's exact test were used to compare the rates between groups.All differences between groups were compared using the Bonferroni method for multiple comparisons.Spearman correlation analysis was used to test the correlation of the data.The test level(α)was 0.05,and a two-sided P<0.05 was considered statistically significant.RESULTS The positive expression rate and expression intensity of PEDF were gradually decreased in the normal control group,adenoma group,and CRC group(100%vs 78%vs 50%,χ^(2)=34.430,P<0.001;++~++vs+~++vs-~+,H=94.059,P<0.001),while VEGF increased gradually(0%vs 68%vs 96%,χ^(2)=98.35,P<0.001;-vs-~+vs++~+++,H=107.734,P<0.001).In the CRC group,the positive expression rate of PEDF decreased with the increase of differen-tiation degree,invasion depth,lymph node metastasis,distant metastasis,and TNM stage(χ^(2)=20.513,4.160,5.128,6.349,5.128,P<0.05);the high expression rate of VEGF was the opposite(χ^(2)=10.317,13.134,17.643,21.844,17.643,P<0.05).In the colorectal adenoma group,the expression intensity of PEDF correlated negatively with CD31-MVD(r=-0.601,P<0.001),whereas VEGF was not significantly different(r=0.258,P=0.07).In the CRC group,the expression intensity of PEDF correlated negatively with the expression intensity of CD31-MVD and VEGF(r=-0.297,P<0.05;r=-0.548,P<0.05),while VEGF expression intensity was positively related to CD31-MVD(r=0.421,P=0.002).CONCLUSION It is possible that PEDF can be used as a new treatment and prevention target for CRC by upregulating the expression of PEDF while inhibiting the expression of VEGF.
文摘Glioblastoma multiforme(GBM)is an aggressive primary brain tumor characterized by extensive heterogeneity and vascular proliferation.Hypoxic conditions in the tissue microenvironment are considered a pivotal player leading tumor progression.Specifically,hypoxia is known to activate inducible factors,such as hypoxia-inducible factor 1alpha(HIF-1α),which in turn can stimulate tumor neo-angiogenesis through activation of various downward mediators,such as the vascular endothelial growth factor(VEGF).Here,we aimed to explore the role of HIF-1α/VEGF immunophenotypes alone and in combination with other prognostic markers or clinical and image analysis data,as potential biomarkers of GBM prognosis and treatment efficacy.We performed a systematic review(Medline/Embase,and Pubmed database search was completed by 16th of April 2024 by two independent teams;PRISMA 2020).We evaluated methods of immunoassays,cell viability,or animal or patient survival methods of the retrieved studies to assess unbiased data.We used inclusion criteria,such as the evaluation of GBM prognosis based on HIF-1α/VEGF expression,other biomarkers or clinical and imaging manifestations in GBM related to HIF-1α/VEGF expression,application of immunoassays for protein expression,and evaluation of the effectiveness of GBM therapeutic strategies based on HIF-1α/VEGF expression.We used exclusion criteria,such as data not reporting both HIF-1αand VEGF or prognosis.We included 50 studies investigating in total 1319 GBM human specimens,18 different cell lines or GBM-derived stem cells,and 6 different animal models,to identify the association of HIF-1α/VEGF immunophenotypes,and with other prognostic factors,clinical and macroscopic data in GBM prognosis and therapeutic approaches.We found that increased HIF-1α/VEGF expression in GBM correlates with oncogenic factors,such as miR-210-3p,Oct4,AKT,COX-2,PDGF-C,PLDO3,M2 polarization,or ALK,leading to unfavorable survival.Reduced HIF-1α/VEGF expression correlates with FIH-1,ADNP,or STAT1 upregulation,as well as with clinical manifestations,like epileptogenicity,and a favorable prognosis of GBM.Based on our data,HIF-1αor VEGF immunophenotypes may be a useful tool to clarify MRI-PET imaging data distinguishing between GBM tumor progression and pseudoprogression.Finally,HIF-1α/VEGF immunophenotypes can reflect GBM treatment efficacy,including combined first-line treatment with histone deacetylase inhibitors,thimerosal,or an active metabolite of irinotecan,as well as STAT3 inhibitors alone,and resulting in a favorable tumor prognosis and patient survival.These data were supported by a combination of variable methods used to evaluate HIF-1α/VEGF immunophenotypes.Data limitations may include the use of less sensitive detection methods in some cases.Overall,our data support HIF-1α/VEGF’s role as biomarkers of GBM prognosis and treatment efficacy.

文摘In this article,an article published in the World Journal of Gastrointestinal Oncology,which focuses on whether the expression of programmed death-ligand 1(PD-L1)affects the effectiveness of chemotherapy regimens,including bevacizumab,in treating patients with colorectal cancer(CRC).Through neutralization of vascular endothelial growth factor(VEGF),bevacizumab inhibits tumor angiogenesis,impairing neovascularization and thereby depriving the tumor of essential nutrients and oxygen.Conversely,PD-L1 binding to VEGF receptor 2 promotes angiogenesis,supporting tumor vasculature.The interplay between these pathways complicates the assessment of bevacizumab’s efficacy in cancer therapy,notably in CRC,where VEGF and PD-L1 significantly affect treatment response.This review examines metastatic CRC treatment strategies,focusing on bevacizumab’s mechanism of action and the role of PD-L1 in this therapeutic context.

Awareness campaigns were the most effective means of communication for 170 cases (75.2%). Sixteen (16) people (35.6%) were taking antihypertensive medication. Walking was the most popular physical activity for 102 people (45%). People with a balanced diet were in the majority, with 174 respondents (77.0%). Conclusion: NCDs are a major cause of morbidity and mortality. It is essential to develop and implement a prevention and management program.
文摘Introduction: Obesity and overweight are a public health problem. The general objective was to determine the epidemiological aspects of obesity, overweight and associated risk factors in a semi-urban environment. Patients and Methods: This was a cross-sectional, descriptive study conducted on November 28 and 29, 2023 in Sébikotane. It focused on volunteers for screening for chronic non-communicable diseases. Epidemiological and clinical data were evaluated. Results: One hundred and twenty-nine cases of obesity were recorded (28%). Two hundred and eighty-two cases were overweight or obese (61.3%). The mean age was 49.55 years, with a standard deviation of 12.41 years. The age group [40 - 49 years] was the most representative, with 85 cases (30.1%), and the majority were female, with 264 cases (93.6%). Primary education was the most common, with 75 cases (46.3%). Grade 1 obesity concerned ninety-seven cases (75.2%), and diabetes was present in thirty cases (23%). Hypertension was present in ninety-five cases (33.7%). Obesity was more marked in the age group [40 - 49 years] with 45 cases (36%). Conclusion: Obesity and overweight are a major cause of morbidity and mortality. The development and implementation of a prevention and management program is essential.
文摘Context: Non-communicable diseases, including hypertension, are major causes of complications during pregnancy, posing significant risks to maternal and fetal health. Pregnancy increases cardiovascular risks, particularly through the development of gestational hypertension and preeclampsia, requiring early screening and close monitoring to prevent adverse outcomes. Objectives: This study aimed to evaluate the frequency of cardiovascular risk factors in pregnant women in Senegal and identify associated socio-behavioral and economic determinants. Methodology: A descriptive, analytical cross-sectional study with prospective data collection was conducted over three months (April 10 to July 10, 2023). The study included pregnant women aged 15 and older from three public hospital maternity wards in Senegal. We studied sociodemographic aspects, cardiovascular risk factors, and collected information on previous and current pregnancies, including the number of pregnancies, parity, miscarriages, the number of prenatal consultations, and the number of fetuses. Written consent was obtained. A p-value ≤ 0.05 was considered statistically significant. Results: A total of 222 pregnant women were enrolled, representing 28% of prenatal consultations. The average age was 29.18 years (range 15 - 47). Most participants (90%) lived in Dakar suburbs, 74.20% had no medical coverage, 84% worked in the informal sector (p = 0.043), and 18% had no education. Among them, 30.63% were in their first pregnancy, 34% were nulliparous, and 3.15% were grand multiparous. The average number of prenatal visits was 3.5, with about 40% having more than four visits. Risk factors included hypertension (17%), more prevalent in women over 30 (p = 0.043), diabetes (4%), and smoking (2%). Conclusion: The study highlights critical prenatal health needs and socio-economic challenges faced by pregnant women, emphasizing the need for targeted strategies to improve healthcare access and health education.
文摘Introduction: Non-communicable diseases (NCDs) are on the increase in several sectors of activity. The aim of the study was to determine the frequencies of cardiovascular risk factors (CVRF) and factors associated with hypertension among hotel workers in the city of Bohicon. Methods: This was a descriptive and analytical cross-sectional study conducted in the period from December 2018 to January 2019. The variables studied were sociodemographic, occupational, anthropometric and behavioral. Participant recruitment was exhaustive. A standardized questionnaire inspired by the STEPS-WHO questionnaire was used for data collection. After the descriptive analysis, a bivariate analysis was performed using Pearson’s Chi-square test or Fisher’s test at the 5% threshold. Results: A total of 101 workers, 53 (52.47%) of them male, participated in the study. The mean age was 30.60 ± 8.20 years, with extremes of 18 and 55 years. The frequencies of the main risk factors were: 68.32% sitting position > 6 hours/day;38.61% shift work;21.78% high psychological demand, 82.18% low decision latitude, 24.75% low social support, 21.78% occupational stress;7 (6.93%) harmful alcohol consumption;6.93% tobacco consumption;48.51% insufficient physical activity;98.02% insufficient fruit and vegetable consumption;59.41% overweight;14.85% HTA. Factors associated with hypertension were: sex, age and marital status. Conclusion: Occupational factors need to be taken into account when assessing CVRFs. NCD control programs are needed in all sectors of activity. A larger study is needed in the hotel sector.
文摘BACKGROUND Gastric cancer(GC)is one of the most common malignant tumors in the world,and its prognosis is closely related to many factors.In recent years,the incidence of vascular thrombosis in patients with GC has gradually attracted increasing attention,and studies have shown that it may have a significant impact on the survival rate and prognosis of patients.However,the specific mechanism underlying the association between vascular thrombosis and the prognosis of patients with GC remains unclear.AIM To analyze the relationships between vascular cancer support and other clinicopathological factors and their influence on the prognosis of patients with GC.METHODS This study retrospectively analyzed the clinicopathological data of 621 patients with GC and divided them into a positive group and a negative group according to the presence or absence of a vascular thrombus.The difference in the 5-year cumulative survival rate between the two groups was compared,and the relationships between vascular cancer thrombus and other clinicopathological factors and their influence on the prognosis of patients with GC were analyzed.RESULTS Among 621 patients with GC,the incidence of vascular thrombi was 31.7%(197 patients).Binary logistic regression analysis revealed that the degree of tumor differentiation,depth of invasion,and extent of lymph node metastasis were independent influencing factors for the occurrence of vascular thrombi in GC patients(P<0.01).The trend of the χ^(2) test showed that the degree of differentiation,depth of invasion,and extent of lymph node metastasis were linearly correlated with the percentage of vascular thrombi in GC patients(P<0.01),and the correlation between lymph node metastasis and vascular thrombi was more significant(r=0.387).Univariate analysis revealed that the 5-year cumulative survival rate of the positive group was significantly lower than that of the negative group(46.7%vs 73.3%,P<0.01).Multivariate analysis revealed that age,tumor diameter,TNM stage,and vascular thrombus were independent risk factors for the prognosis of GC patients(all P<0.05).Further stratified analysis revealed that the 5-year cumulative survival rate of stage Ⅲ GC patients in the thrombolase-positive group was significantly lower than that in the thrombolase-negative group(36.1%vs 51.4%;P<0.05).CONCLUSION Vascular cancer status is an independent risk factor affecting the prognosis of patients with GC.The combination of vascular cancer suppositories and TNM staging can better judge the prognosis of patients with GC and guide more reasonable treatment.
文摘In Mali, few studies have been conducted on the prevalence of cardiovascular risk factors and diseases according to place of residence. The aim of this study was to assess the prevalence of risk factors and cardiovascular diseases according to residents in town of Bougouni and its rural area (southern Mali). Methods: This was a retrospective descriptive study from February 2019 to March 2024. All patients who visited the “CENTRE MEDICAL DE BOUGOUNI” clinic with known or suspected heart disease during the study period were included. Data were collected from medical records. Incomplete or unusable records were excluded. Data were processed using SPS version 22 software. Results: we included 452 patients with an average age of 50 ± 19 years. High blood pression has been found in 42.70% of cases, with higher prevalence in urban areas (47.01%) than in rural areas (41.50%). Diabetes and smoking were found respectively 5.31% and 8.19% in our population. The prevalence of diabetes was higher in urban areas (5.97%) than rural area (5.35%). smoking prevalence was higher in rural areas (8.49%) than urban areas (6.72%). Alcoholism was found in 2.21% of cases with a little difference between rural area (2.24%) and urban area (2.20%). 31.63% of our patients had no cardiovascular factor. Dyspnea was the reason of consultation in 5.75% of cases and atypical precordialgia in 13.72%. Headaches and dizziness in 8.63% of cases and 21.90% of patients presented other non-specific symptoms. Diagnosis of idiopathic dilated cardiomyopathy was found in 23.45% of cases with higher prevalence in rural areas (28.30%) than urban areas (13.43%). Ischaemic heart disease accounted for 9.29% of cases with a higher prevalence in rural areas (10.38%) than in urban areas (6.71%). PPCMs accounted for 5.98% of cases, with a slight increase in urban areas (6.66%) compared with rural areas (5.68%). Rheumatic valvulopathy accounted for 2.21% of cases;2.84% in rural areas and 0.74% in urban areas. Other valvular diseases accounted for 3.76% of cases;4.73% in rural areas and 1.48% in urban areas. Right heart diseases accounted for 3.98% of cases and stroke for 1.77%. Conclusion: The prevalence of cardiovascular risk factors and heart diseases is high in the rural and urban population of the town of Bougouni and its surroundings (Mali). Excepted smoking, the prevalence of other CV risk factors is higher in urban areas, whereas the prevalence of idiopathic dilated cardiomyopathy and ischemic heart disease is higher in rural areas. These data could serve as a basis for developing tailored preventive strategies, depending on the place of residence.
文摘BACKGROUND At present,the influencing factors of social function in patients with residual depressive symptoms are still unclear.Residual depressive symptoms are highly harmful,leading to low mood in patients,affecting work and interpersonal communication,increasing the risk of recurrence,and adding to the burden on families.Studying the influencing factors of their social function is of great significance.AIM To explore the social function score and its influencing factors in patients with residual depressive symptoms.METHODS This observational study surveyed patients with residual depressive symptoms(case group)and healthy patients undergoing physical examinations(control group).Participants were admitted between January 2022 and December 2023.Social functioning was assessed using the Sheehan Disability Scale(SDS),and scores were compared between groups.Factors influencing SDS scores in patients with residual depressive symptoms were analyzed by applying multiple linear regression while using the receiver operating characteristic curve,and these RESULTS The SDS scores of the 158 patients with depressive symptoms were 11.48±3.26.Compared with the control group,the SDS scores and all items in the case group were higher.SDS scores were higher in patients with relapse,discon-tinuous medication,drug therapy alone,severe somatic symptoms,obvious residual symptoms,and anxiety scores≥8.Disease history,medication compliance,therapy method,and residual symptoms correlated positively with SDS scores(r=0.354,0.414,0.602,and 0.456,respectively).Independent influencing factors included disease history,medication compliance,therapy method,somatic symptoms,residual symptoms,and anxiety scores(P<0.05).The areas under the curve for predicting social functional impairment using these factors were 0.713,0.559,0.684,0.729,0.668,and 0.628,respectively,with sensitivities of 79.2%,61.8%,76.8%,81.7%,63.6%,and 65.5%and specificities of 83.3%,87.5%,82.6%,83.3%,86.7%,and 92.1%,respectively.CONCLUSION The social function scores of patients with residual symptoms of depression are high.They are affected by disease history,medication compliance,therapy method,degree of somatic symptoms,residual symptoms,and anxiety.
文摘Microvascular complications are one of the major causes of morbidity and mortality worldwide among patients with diabetes mellitus (DM). More than 50% of Nyeri County Referral Hospital (NCRH) admissions result from non-communicable diseases (NCDs) and over 55% of hospital deaths are attributable to NCDs. In Kenya, Nyeri County has the highest prevalence of diabetes mellitus compared to other counties. This study therefore sought to assess the prevalence of microvascular complications and the associated risk factors among patients attending Nyeri County Referral Hospital in Kenya. A hospital-based cross-sectional study was conducted on 314 DM patients on follow-up at NCRH from August 2022 to October 2022. Data were analyzed using STATA version 17. Univariate and multivariate logistic regression analyses are used to determine the risk factors associated with Microvascular complications of DM. Among the 314 participants with DM, 58% were females. The overall prevalence of Microvascular complications (MVCs) is 36.62%. Diabetic peripheral neuropathy was the most frequent complication (27.4%). Inadequate physical exercise was a risk factor for all MVCs. Age, marital status, and level of education were risk factors for neuropathy while smoking and alcohol intake were risk factors for nephropathy. Non-smokers were 98% less likely to have nephropathy (OR = 0.024;95% CI 0.003 - 0.145). The odds of those who exercise once weekly getting retinopathic complications reduced by 83% (OR = 0.18, 95% CI 0.049 - 0.398) compared to those who exercise daily. The findings highlight the implication of lifestyle factors in the development of MVCs among DM patients. Therefore, benefits of microvascular complications prevention should thus be factored into the management of patients with diabetes mellitus.
文摘The aim of this study was to determine the prevalence of diabetes and other cardiovascular risk factors (smoking, obesity and high blood pressure) and to evaluate the WHO Global Cardiovascular Risk Score in the population of people suspected of COVID-19 infection aged 40 years or older. Material and Methods: This was a descriptive cross-sectional study conducted at the Donka University Hospital from June 1 to July 4, 2020 on subjects received for COVID-19 screening. Results: The prevalence of diabetes in patients suspected of COVID-19 was 7.8% comprising 1.2% of known diabetics and 6.8% of new cases. The prevalence of active smoking was 14.0%. That of sedentary lifestyle and obesity were 10.6% and 17.2% respectively. We found a prevalence of hypertension estimated at 45%, it was unknown in 76.47% of cases. In this series, 33.2% of patients had a high and very high cardiovascular risk (WHO scores). Conclusion: This study reveals a fairly high prevalence of diabetes and other cardiovascular risk factors in the population of people suspected of COVID-19. This observation should lead to the implementation of effective strategies for the prevention of non-communicable diseases in Guinea.
