The levels of the inflammatory cytokines interleukin-17(IL-17), tumour necrosis factor-α(TNF-α), and interferon-γ(IFN-γ) were measured by enzyme-linked immunosorbent assay. The expression of mi R-125 a/b was assessed by quantitative polymerase chain reaction(q PCR).RESULTS Twenty-nine A-CD patients, 37 R-CD patients, and 37 HCs were included in the study. Plasma mi R-125 a expression was decreased in A-CD patients comparedwith that in R-CD patients(P < 0.001) and HCs(P < 0.001). mi R-125 a expression levels enabled the differentiation of A-CD from R-CD patients [area under curve(AUC) = 0.854] and from HCs(AUC = 0.780), whereas mi R-125 b expression did not. mi R-125 a was negatively correlated with C-reaction protein(CRP)(P = 0.017), erythrocyte sedimentation rate(ESR)(P = 0.026), Crohn's disease activity index(CDAI)(P = 0.003), IL-17(P = 0.015), and TNF-α(P = 0.004) in A-CD patients. Furthermore, mi R-125 a was negatively associated with CRP(P = 0.038) and CDAI(P = 0.021) in R-CD patients. Regarding mi R-125 b, no association with CRP, CDAI, IL-17, TNF-α, or IFN-γ was found in A-CD or in R-CD patients. mi R-125 a levels gradually increased in A-CD patients who achieved clinical remission(P = 0.009) after 3-mo treatment, whereas they remained unchanged among patients who failed to achieve remission. No changes in mi R-125 b expression were detected in remission or non-remission patients after treatment. CONCLUSION Circulating mi R-125 a but not mi R-125 b is decreased in patients with active disease status and negatively correlates with disease severity and inflammatory cytokines in patients with CD.展开更多

METHODS:Records from 1996 to 2001 were exam- ined to create a database of UC patients seen in the London Health Sciences Centre South Street Hospital Inflammatory Bowel Disease Clinic.To be included, patients'charts were required to have information of their disease presentation and a minimum of 5 years of follow-up.Charts were reviewed using standardized data collection forms.Disease severity was generated during the chart review process,and non-endoscopic Mayo Score criteria were collected into a composite. RESULTS:One hundred and two consecutive patients'data were entered into the database.Demographic analyses revealed that 51%of the patients were male, the mean age at diagnosis was 39 years,13.7%had a first degree relative with inflammatory bowel disease (IBD),61.8%were nonsmokers and 24.5%were ex-smokers.In 22.5%of patients the disease was limited to the rectum,in 21.6%disease was limited to the sigmoid colon,in 22.5%disease was limited to the left colon,and 32.4%of patients had pancolitis. Standard multiple regression analysis which regressed a composite of physician global assessment of disease severity,average number of bowel movements,and average amount of blood in bowel movements on year of diagnosis and age at time of diagnosis was significant,R 2=0.306,F(7,74)=4.66,P<0.01. Delay from symptoms to diagnosis of UC,gender, family history of IBD,smoking status and disease severity at the time of diagnosis didnot significantly predict the composite measure. CONCLUSION:UC severity is associated with younger age at diagnosis and year of diagnosis in a longitudinal cohort of UC patients,and may identify prognostic UC indicators.展开更多

Hyperspectral remote sensing data generally have high spectral resolution, which could be very useful for detecting disease stress in green vegetation at the leaf and canopy levels. In this study, hyperspectral reflectances of rice in the laboratory and field were measured to characterize the spectral regions and wavebands, which were the most sensitive to rice brown spot infected by Bipolaris oryzae （Helminthosporium oryzae Breda. de Hann）. Leaf reflectance increased at the ranges of 450 to 500 nm and 630 to 680 nm with the increasing percentage of infected leaf surface, and decreased at the ranges of 520 to 580 nm, 760 to 790 nm, 1550 to 1750 nm, and 2080 to 2350 nm with the increasing percentage of infected leaf surface respectively. The sensitivity analysis and derivative technique were used to select the sensitive wavebands for the detection of rice brown spot infected by B. oryzae. Ratios of rice leaf reflectance were evaluated as indicators of brown spot. R669/R746 （the reflectance at 669 nm divided by the reflectance at 746 nm, the following ratios may be deduced by analogy）, R702/R718, R692/R530, R692/R732, R535/R746, R521/R718, and R569/R718 increased significantly as the incidence of rice brown spot increased regardless of whether it＇s at the leaf or canopy level. R702/R718, R692/R530, R692/R732 were the best three ratios for estimating the disease severity of rice brown spot at the leaf and canopy levels. This result not only confirms the capability of hyperspectral remote sensing data in characterizing crop disease for precision pest management in the real world, but also testifies that the ratios of crop reflectance is a useful method to estimate crop disease severity.展开更多

This research aimed to investigate the relationship between symptom clusters, disease severity, and cerebral blood flow. Twenty-seven patients （16 males, 11 females） with stages 4 and 5 end-stage renal disease were enrolled, along with 25 healthy controls. All patients underwent depressive mood assessment and brain single photon emission computed tomography. The statistical probabilistic anatomical map images were used to calculate the brain single photon emission computed tomography counts. Asymmetric index was acquired and Pearson correlation analysis was performed to analyze the correlation between symptom factors, severity, and regional cerebral blood flow. The depression factors of the Hamilton Depression Rating Scale showed a negative correlation with cerebral blood flow in the left amygdale. The insomnia factor showed negative correlations with cerebral blood flow in the left amygdala, right superior frontal gyrus, right middle frontal gyrus, and left middle frontal gyrus. The anxiety factor showed a positive correlation with cerebral glucose metabolism in the cerebellar vermis and a negative correlation with cerebral glucose metabolism in the left globus pailidus, right inferior frontal gyrus, both temporal poles, and left parahippocampus. The overall depression severity （total scores of Hamilton Depression Rating Scale） was negatively correlated with the statistical probabilistic anatomical map results in the left amygdala and right inferior frontal gyrus. In conclusion, our results demonstrated that the disease severity and extent of cerebral blood flow quantified by a probabilistic brain atlas was related to various brain areas in terms of the overall severity and symptom factors in end-stage renal disease patients.展开更多

The objective of this study was to analyze the role of early hyperglycemia in predicting the severity of COVID-19 illness and mortality. <strong>Method:</strong> Retrospective study on 259 patients with COVID-19 with measurement of average glucose during 24 hours of admission. Association of Early Hyperglycemia categorized as <180 mg/dl or >180 mg/dl;was studied with mortality, requirement of ICU stay and prognostic markers. <strong>Results: </strong>Early hyperglycemia (>180 mg/dl) revealed a higher median value for CRP (109 mg/l [IQR;48 - 199]) in comparison to <180 mg/dl group (86 mg/l [IQR;26.3 - 153]) p = 0.03. ICU stay was higher in >180 mg/dl group;24 (15.9%) vs 14 patients (13%) [p = 0.51] in the <180 mg/dl group. Mortality in the group > 180 mg/dl was 8 (5.3%) while <180 mg/dl had a mortality rate of 4 (3.7%) [p = 0.547]. <strong>Conclusion:</strong> Hyperglycemia in the first 24 hours may anticipate an increased risk of ICU stay and a higher mortality rate. It may be a possible predictor of disease severity.展开更多

Vitamin D levels below normal are associated with hospital stay, increased incidence of adverse prognosis and increased mortality of a number of diseases. Whether there is a relationship between vitamin D levels and infection or sepsis in the critically ill is still unclear. This study will explore the relationship between vitamin D levels and risk of infection, assessment for disease severity, and predictor of mortality. Methods To evaluate the value of vitamin D in intensive care unit （ICU） cases to sepsis, severity and prognosis assessment, high performance liquid chromatography and tandem mass spectrometry were used to measure the concentrations of vitamin D in sera of critically ill patients. The serum samples were drawn within the first 24 hours of ICU admission. Results The study included 206 people, 50 healthy controls, 51 ICU control patients and 105 ICU diagnosed with sepsis. Critically ill ICU patients （ICU sepsis and ICU control group） had lower vitamin D concentration than normal people, but septic patients showed no significant reduction of vitamin D concentration when compared with critically ill patients with no positive etiological evidence. For assessment of disease severity, there were very low negative correlations between APACHE II, SAPS II and SOFA scores and vitamin D level. Additionally, patients of different 25-（OH）D levels showed no difference whether in terms of 28-day survival （χ2=1.78, P=0.776） or 90-day survival （χ2=4.12, P=0.369）. Multivariate Logistic regression demonstrated that APECHE II and SAPS II scores were independent risk factors to deaths caused by sepsis. Conclusion Clinically, serum concentration of vitamin D is not an indicator for diagnosis and assessment in critically ill patients （ClinicalTrial.gov identifier NCT01636232）.展开更多

This study aimed to analyze the satisfaction with drug therapies for RA according to the levels of disease severity (patientassessed) and proportions of treatment cost to household income.Methods:This was a subgroup study of a cross-sectional study in patients with RA and their physicians. The patients were subdivided into different subgroups based on their self-assessed severity of RA and on the proportions of treatment cost to household income (<10%, 10-30%, 31-50%, and >50%). The Treatment Satisfaction Questionnaire for Medication version II was used to assess patients’ treatment satisfaction.Results:When considering all medications, effectiveness, convenience, and global satisfaction scores were lower in the severe and moderate RA subgroups than those in the mild and extremely mild RA subgroups (all P < 0.001). Effectiveness, side effects, and convenience scores were higher in the <10% subgroup compared to those in the >50% subgroup (all P < 0.05). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup ( F = 13.183, P = 0.004). For biological diseasemodifying anti-rheumatic drugs, effectiveness and convenience scores were lower in the severe RA subgroup than those in the extremely mild RA subgroup (both P < 0.05). Convenience score was higher in the <10% subgroup compared to that in the 31% to 50% and >50% subgroups ( F = 12.646, P = 0.005). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup ( F = 8.794, P = 0.032). Conclusion:Higher disease severity and higher financial burden were associated with lower patient satisfaction.展开更多

We investigated the frequency and factors associated with sleep-related symptoms in patients with MSA and the impact of sleep disturbances on disease severity.Methods: This cross-sectional study involved 165 patients with MSA. Three sleep-related symptoms, namely Parkinson’s disease (PD)-related sleep problems (PD-SP), excessive daytime sleepiness (EDS), and rapid eye movement sleep behavior disorder (RBD), were evaluated using the PD Sleep Scale-2 (PDSS-2), Epworth Sleepiness Scale (ESS), and RBD Screening Questionnaire (RBDSQ), respectively. Disease severity was evaluated using the Unified MSA Rating Scale (UMSARS).Results: The frequency of PD-SP (PDSS-2 score of ≥18), EDS (ESS score of ≥10), and RBD (RBDSQ score of ≥5) in patients with MSA was 18.8%, 27.3%, and 49.7%, respectively. The frequency of coexistence of all three sleep-related symptoms was 7.3%. Compared with the cerebellar subtype of MSA (MSA-C), the parkinsonism subtype of MSA (MSA-P) was associated with a higher frequency of PD-SP and EDS, but not of RBD. Binary logistic regression revealed that the MSA-P subtype, a higher total UMSARS score, and anxiety were associated with PD-SP;that male sex, a higher total UMSARS score, the MSA-P subtype, and fatigue were associated with EDS;and that male sex, a higher total UMSARS score, and autonomic onset were associated with RBD in patients with MSA. Stepwise linear regression showed that the number of sleep-related symptoms (PD-SP, EDS, and RBD), disease duration, depression, fatigue, and total Montreal Cognitive Assessment score were predictors of disease severity in patients with MSA.Conclusions: Sleep-related disorders were associated with both MSA subtypes and the severity of disease in patients with MSA, indicating that sleep disorders may reflect the distribution and degree of dopaminergic/non-dopaminergic neuron degeneration in MSA.展开更多

This study focused on understanding COVID-19’s clinical presentation, disease progression, and outcomes among hospitalized pediatric patients. Additionally, it sought to investigate the impact of concurrent chronic medical conditions on disease severity. Methods: Conducted retrospectively between September 2020 and December 2021, this study observed pediatric patients (below 18 years) hospitalized with confirmed COVID-19 at an Irbid, Jordan tertiary healthcare center. Patients meeting inclusion criteria, including a positive nasal swab PCR test and hospitalization need, were analyzed. Epidemiological and clinical data were collected and segregated into two groups (A and B) based on the presence of chronic conditions. Comparative analysis encompassed presentation, disease trajectory, and outcomes between these groups. Results: Among 451 tested positive patients, 112 were included in the study. Significant differences emerged between the two pediatric groups hospitalized for COVID-19. Those with concurrent chronic illnesses exhibited heightened symptom severity—fever, dyspnea, fatigue—and a higher incidence of abnormal chest radiographs, often requiring intensive care and experiencing elevated mortality rates. Conclusion: This study underscores the criticality of prioritizing COVID-19 management strategies for pediatric patients with pre-existing chronic medical conditions. The findings highlight the increased vulnerability and poorer outcomes experienced by this subgroup, emphasizing the necessity for tailored interventions and focused care approaches.展开更多

OBJECTIVE： To observe the effect of lower dose of aspirin during taking for a long time on disease degree of disease following onset of acute cerebral infarction. DESIGN： Grouping according to the admission time and 1：1 paired observation.SETTING ： Department of Neurology, Qilu Hospital of Shandong University.PARTICIPANTS ： The participants in present study were 321 patients with acute cerebral infarction who received treatments in the Department of Neurology, Qilu Hospital of Shandong University from January 1999 to June 2000. There were 190 male and 131 female ,with mean （65±11 ）years of age. Inclusive criteria： ① A focal neurological disturbance occurred suddenly and had lasted for more than 24 hours, patients were admitted within 3 days after onset of disease; ② A computed tomography of the brain was performed and excluded hemorrhage in all patients; ③ The patients were proved internal carotid occlusions by clinical features and image findings; ④ The functions of limbs were normal （before the first stroke） or almost normal （before the second stroke）. Exclusive criteria：①The patients who had have cardiogenic cerebral embolism; ②The patients who had taken warfarin orally and other platelet agglutination drugs. METHODS ：①All the patients were divided into 2 groups according to whether they had taken aspirin before： aspirin-treated group （n=110） and blank control group （n=211）. there were 70 male and 40 female in aspirin-treated group, with average（65±10） years of age.All patients had taken 50-100 mg/d aspirin for 6 months to 10 years before onset. There were 120 male and 91 female in blank control group, with average （65±13） years of age. Patients received a clinical scoring within 3 days and similar therapeutic measures （such as anti-platelet agglutination, improving cerebral circulation and metabolism-promoting reagent）. Two groups of patients had the same basic conditions except for taking aspirin or not before. ②The matched pairs were made between 50 cases selected from aspirin-treated group and 50 cases from non-aspirin-treated groups according to age, gender, and other stroke risk factors. ③ Evaluation： Degree of disease after onset was evaluated by means of Acute Cerebral Infarction Clinical Neurologic Impairment Degree Scoring Standard of Carotid Artery System. MAIN OUTCOME MEASURES： Acute Cerebral Infarction Clinical Neurologic Impairment Degree Scoring Standard of Carotid Artery System.

However there is scanty information on the usefulness of the combined APACHE-O scoring system in Asian patients. This study aimed to compare the accuracy of Ranson, APACHE-Ⅱ and APACHE-O systems in assessing severity of acute pancreatitis in a local Chinese population. METHODS: One hundred and one consecutive patients with acute pancreatitis were prospectively studied. Body mass index (BMI) was measured on admission. Ranson score, APACHE-Ⅱ and APACHE-O scores were recorded on admission and at 48 hours. By adopting the cut-off levels and definitions advocated in the Atlanta consensus for severe disease, the diagnostic accuracy of the three scoring systems was compared by the area under the curve (AUC) under the receiver operator characteristic curve. RESULTS: Of the 101 patients, 12 (11.9%) patients suffered from severe pancreatitis. Obesity was uncommon and only two patients (2.0%) had BMI >30. Eighty-two (81.2%) patients were normal weight (BMI≤25) whereas 17 (16.8%) were overweight ( BMI 25-30 ). Overweight or obesity (BMI >25) was not associated with severe pancreatitis (P= 0.40). The AUC for admission scores of Ranson, APACHE-Ⅱ, and APACHE-O systems was 0. 549, 0. 904 and 0. 904, respectively. The AUC for 48-hour scores of Ranson, APACHE-Ⅱ and APACHE-O systems was 0.808, 0.955 and 0.951, respectively. CONCLUSIONS: The APACHE-Ⅱ scoring system is more accurate than the Ranson scoring system of the prediction of severity in acute pancreatitis. Addition of obesity score does not significantly improve the predictive accuracy of the APACHE-Ⅱ system in our local population with a low prevalence of obesity.展开更多
文摘BACKGROUND Sepsis is a life-threatening condition characterized by a dysregulation of the host response to infection that can lead to acute lung injury(ALI)and multiple organ dysfunction syndrome(MODS).Interleukin 6(IL-6)is a pro-inflammatory cytokine that plays a crucial role in the pathogenesis of sepsis and its complications.AIM To investigate the relationship among plasma IL-6 levels,risk of ALI,and disease severity in critically ill patients with sepsis.METHODS This prospective and observational study was conducted in the intensive care unit of a tertiary care hospital between January 2021 and December 2022.A total of 83 septic patients were enrolled.Plasma IL-6 levels were measured upon admission using an enzyme-linked immunosorbent assay.The development of ALI and MODS was monitored during hospitalization.Disease severity was evaluated by Acute Physiology and Chronic Health Evaluation II(APACHE II)and Sequential Organ Failure Assessment(SOFA)scores.RESULTS Among the 83 patients with sepsis,38(45.8%)developed ALI and 29(34.9%)developed MODS.Plasma IL-6 levels were significantly higher in patients who developed ALI than in those without ALI(median:125.6 pg/mL vs 48.3 pg/mL;P<0.001).Similarly,patients with MODS had higher IL-6 levels than those without MODS(median:142.9 pg/mL vs 58.7 pg/mL;P<0.001).Plasma IL-6 levels were strongly and positively correlated with APACHE II(r=0.72;P<0.001)and SOFA scores(r=0.68;P<0.001).CONCLUSIONElevated plasma IL-6 levels in critically ill patients with sepsis were associated with an increased risk of ALI andMODS.Higher IL-6 levels were correlated with greater disease severity,as reflected by higher APACHE II andSOFA scores.These findings suggest that IL-6 may serve as a biomarker for predicting the development of ALI anddisease severity in patients with sepsis.
文摘AIM To determine the association of circulating mi R-125 a/b expression with the risk and disease severity of Crohn's disease(CD), and with inflammatory cytokines.METHODS Plasma samples were collected from patients with active CD(A-CD), or CD in remission(R-CD) and from healthy controls(HCs). The levels of the inflammatory cytokines interleukin-17(IL-17), tumour necrosis factor-α(TNF-α), and interferon-γ(IFN-γ) were measured by enzyme-linked immunosorbent assay. The expression of mi R-125 a/b was assessed by quantitative polymerase chain reaction(q PCR).RESULTS Twenty-nine A-CD patients, 37 R-CD patients, and 37 HCs were included in the study. Plasma mi R-125 a expression was decreased in A-CD patients comparedwith that in R-CD patients(P < 0.001) and HCs(P < 0.001). mi R-125 a expression levels enabled the differentiation of A-CD from R-CD patients [area under curve(AUC) = 0.854] and from HCs(AUC = 0.780), whereas mi R-125 b expression did not. mi R-125 a was negatively correlated with C-reaction protein(CRP)(P = 0.017), erythrocyte sedimentation rate(ESR)(P = 0.026), Crohn's disease activity index(CDAI)(P = 0.003), IL-17(P = 0.015), and TNF-α(P = 0.004) in A-CD patients. Furthermore, mi R-125 a was negatively associated with CRP(P = 0.038) and CDAI(P = 0.021) in R-CD patients. Regarding mi R-125 b, no association with CRP, CDAI, IL-17, TNF-α, or IFN-γ was found in A-CD or in R-CD patients. mi R-125 a levels gradually increased in A-CD patients who achieved clinical remission(P = 0.009) after 3-mo treatment, whereas they remained unchanged among patients who failed to achieve remission. No changes in mi R-125 b expression were detected in remission or non-remission patients after treatment. CONCLUSION Circulating mi R-125 a but not mi R-125 b is decreased in patients with active disease status and negatively correlates with disease severity and inflammatory cytokines in patients with CD.

文摘AIM:To understand the demographic characteristics of patients in Southwestern Ontario,Canada with ulcerative colitis(UC)in order to predict disease severity. METHODS:Records from 1996 to 2001 were exam- ined to create a database of UC patients seen in the London Health Sciences Centre South Street Hospital Inflammatory Bowel Disease Clinic.To be included, patients'charts were required to have information of their disease presentation and a minimum of 5 years of follow-up.Charts were reviewed using standardized data collection forms.Disease severity was generated during the chart review process,and non-endoscopic Mayo Score criteria were collected into a composite. RESULTS:One hundred and two consecutive patients'data were entered into the database.Demographic analyses revealed that 51%of the patients were male, the mean age at diagnosis was 39 years,13.7%had a first degree relative with inflammatory bowel disease (IBD),61.8%were nonsmokers and 24.5%were ex-smokers.In 22.5%of patients the disease was limited to the rectum,in 21.6%disease was limited to the sigmoid colon,in 22.5%disease was limited to the left colon,and 32.4%of patients had pancolitis. Standard multiple regression analysis which regressed a composite of physician global assessment of disease severity,average number of bowel movements,and average amount of blood in bowel movements on year of diagnosis and age at time of diagnosis was significant,R 2=0.306,F(7,74)=4.66,P<0.01. Delay from symptoms to diagnosis of UC,gender, family history of IBD,smoking status and disease severity at the time of diagnosis didnot significantly predict the composite measure. CONCLUSION:UC severity is associated with younger age at diagnosis and year of diagnosis in a longitudinal cohort of UC patients,and may identify prognostic UC indicators.

文摘Large-scale farming of agriculture crops requires real-time detection of disease for field pest management. Hyperspectral remote sensing data generally have high spectral resolution, which could be very useful for detecting disease stress in green vegetation at the leaf and canopy levels. In this study, hyperspectral reflectances of rice in the laboratory and field were measured to characterize the spectral regions and wavebands, which were the most sensitive to rice brown spot infected by Bipolaris oryzae （Helminthosporium oryzae Breda. de Hann）. Leaf reflectance increased at the ranges of 450 to 500 nm and 630 to 680 nm with the increasing percentage of infected leaf surface, and decreased at the ranges of 520 to 580 nm, 760 to 790 nm, 1550 to 1750 nm, and 2080 to 2350 nm with the increasing percentage of infected leaf surface respectively. The sensitivity analysis and derivative technique were used to select the sensitive wavebands for the detection of rice brown spot infected by B. oryzae. Ratios of rice leaf reflectance were evaluated as indicators of brown spot. R669/R746 （the reflectance at 669 nm divided by the reflectance at 746 nm, the following ratios may be deduced by analogy）, R702/R718, R692/R530, R692/R732, R535/R746, R521/R718, and R569/R718 increased significantly as the incidence of rice brown spot increased regardless of whether it＇s at the leaf or canopy level. R702/R718, R692/R530, R692/R732 were the best three ratios for estimating the disease severity of rice brown spot at the leaf and canopy levels. This result not only confirms the capability of hyperspectral remote sensing data in characterizing crop disease for precision pest management in the real world, but also testifies that the ratios of crop reflectance is a useful method to estimate crop disease severity.

文摘This study adapted a statistical probabilistic anatomical map of the brain for single photon emission computed tomography images of depressive end-stage renal disease patients. This research aimed to investigate the relationship between symptom clusters, disease severity, and cerebral blood flow. Twenty-seven patients （16 males, 11 females） with stages 4 and 5 end-stage renal disease were enrolled, along with 25 healthy controls. All patients underwent depressive mood assessment and brain single photon emission computed tomography. The statistical probabilistic anatomical map images were used to calculate the brain single photon emission computed tomography counts. Asymmetric index was acquired and Pearson correlation analysis was performed to analyze the correlation between symptom factors, severity, and regional cerebral blood flow. The depression factors of the Hamilton Depression Rating Scale showed a negative correlation with cerebral blood flow in the left amygdale. The insomnia factor showed negative correlations with cerebral blood flow in the left amygdala, right superior frontal gyrus, right middle frontal gyrus, and left middle frontal gyrus. The anxiety factor showed a positive correlation with cerebral glucose metabolism in the cerebellar vermis and a negative correlation with cerebral glucose metabolism in the left globus pailidus, right inferior frontal gyrus, both temporal poles, and left parahippocampus. The overall depression severity （total scores of Hamilton Depression Rating Scale） was negatively correlated with the statistical probabilistic anatomical map results in the left amygdala and right inferior frontal gyrus. In conclusion, our results demonstrated that the disease severity and extent of cerebral blood flow quantified by a probabilistic brain atlas was related to various brain areas in terms of the overall severity and symptom factors in end-stage renal disease patients.
文摘Due to the disease's broad clinical spectrum,it is currently unclear how to predict the future prognosis of patients at the time of diagnosis of coronavirus disease 2019(COVID-19).Real-time reverse transcription-polymerase chain reaction(RTPCR)is the gold standard molecular technique for diagnosing COVID-19.The number of amplification cycles necessary for the target genes to surpass a threshold level is represented by the RT-PCR cycle threshold(Ct)values.Ct values were thought to be an adequate proxy for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)viral load.A body of evidence suggests that SARS-CoV-2 viral load is a possible predictor of COVID-19 severity.The link between SARS-CoV-2 viral load and the likelihood of severe disease development in COVID-19 patients is not clearly elucidated.In this review,we describe the scientific data as well as the important findings from many clinical studies globally,emphasizing how viral load may be related to disease severity in COVID-19 patients.Most of the evidence points to the association of SARS-CoV-2 viral load and disease severity in these patients,and early anti-viral treatment will reduce the severe clinical outcomes.
文摘<strong>Background:</strong> Hyperglycemia is an important predictor of prolonged hospitalization and mortality. The objective of this study was to analyze the role of early hyperglycemia in predicting the severity of COVID-19 illness and mortality. <strong>Method:</strong> Retrospective study on 259 patients with COVID-19 with measurement of average glucose during 24 hours of admission. Association of Early Hyperglycemia categorized as <180 mg/dl or >180 mg/dl;was studied with mortality, requirement of ICU stay and prognostic markers. <strong>Results: </strong>Early hyperglycemia (>180 mg/dl) revealed a higher median value for CRP (109 mg/l [IQR;48 - 199]) in comparison to <180 mg/dl group (86 mg/l [IQR;26.3 - 153]) p = 0.03. ICU stay was higher in >180 mg/dl group;24 (15.9%) vs 14 patients (13%) [p = 0.51] in the <180 mg/dl group. Mortality in the group > 180 mg/dl was 8 (5.3%) while <180 mg/dl had a mortality rate of 4 (3.7%) [p = 0.547]. <strong>Conclusion:</strong> Hyperglycemia in the first 24 hours may anticipate an increased risk of ICU stay and a higher mortality rate. It may be a possible predictor of disease severity.

文摘Understanding how human leukocyte antigen(HLA)polymorphism affects both the susceptibility and severity of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection will help to identify individuals at higher risk to better manage and prioritize vaccination at the clinical level and explain the differences in epidemic trends in different regions at the epidemiological level.This study compared the frequencies of HLA class I alleles(HLA-A,B)in 214 coronavirus disease 2019(COVID-19)patients with different disease severity and 35 healthy controls and analyzed the correlations between specific HLA alleles and disease severity and T cell memory.The results showed no significant difference in HLA allele frequencies between COVID-19 patients and healthy controls(P>0.05).The allele HLA-B*13:02 was significantly correlated with the disease severity of COVID-19 patients(P=0.006).After adjustment for age and disease severity,the T cell responses of COVID-19 convalescents with the allele HLA-B*40:01 may be lower at six months(P=0.044)and 12 months(P=0.069).Moreover,these results may be due to their rare peptide anchors by analyzing the binding peptide motifs of these HLA alleles.The study may be valuable for investigating the potential association of specific HLA alleles with SARS-CoV-2 infection.
文摘In this editorial we comment on the article by Pacheco et al published in a recent issue of the World Journal of Gastroenterology.We focus specifically on the burden of illness associated with perianal fistulizing Crohn’s disease(PFCD)and the diagnostic and therapeutic challenges in the management of this condition.Evol-ving evidence has shifted the diagnostic framework for PFCD from anatomical classification systems,to one that is more nuanced and patient-focused to drive ongoing decision making.This editorial aims to reflect on these aspects to help clinicians face the challenge of PFCD in day-to-day clinical practice.
文摘BACKGROUND Pediatric appendicitis is a common cause of abdominal pain in children and is recognized as a significant surgical emergency.A prompt and accurate diagnosis is essential to prevent complications such as perforation and peritonitis.AIM To investigate the predictive value of the systemic immune-inflammation index(SII)combined with the pediatric appendicitis score(PAS)for the assessment of disease severity and surgical outcomes in children aged 5 years and older with appendicitis.METHODS Clinical data of 104 children diagnosed with acute appendicitis were analyzed.The participants were categorized into the acute appendicitis group and chronic appendicitis group based on disease presentation and further stratified into the good prognosis group and poor prognosis group based on prognosis.The SII and PAS were measured,and a joint model using the combined SII and PAS was constructed to predict disease severity and surgical outcomes.RESULTS Significant differences were observed in the SII and PAS parameters between the acute appendicitis group and chronic appendicitis group.Correlation analysis showed associations among the SII,PAS,and disease severity,with the combined SII and PAS model demonstrating significant predictive value for assessing disease severity[aera under the curve(AUC)=0.914]and predicting surgical outcomes(AUC=0.857)in children aged 5 years and older with appendicitis.CONCLUSION The study findings support the potential of integrating the SII with the PAS for assessing disease severity and predicting surgical outcomes in pediatric appendicitis,indicating the clinical utility of the combined SII and PAS model in guiding clinical decision-making and optimizing surgical management strategies for pediatric patients with appendicitis.
文摘Objective:To evaluate relationship between changes in the beneficial bacteria in intensive care unit(ICU)patients and nutritional therapy type.Methods:Ten patients aged≥18 years admitted to the ICU between January and December 2020,were included.Good enteral nutrition was defined as early achievement of target calorie intake through enteral feeding.The ratio of beneficial bacteria at the first and second bowel movements after each patient’s admission was calculated and the patients were classified into the increase or decrease group.Among all patients,five each were in the increase and decrease groups.We investigated patient background,changes in sequential organ failure assessment(SOFA)and acute physiology and chronic health evaluation(APACHE)Ⅱscores,nutritional doses or methods,and clinical outcomes.Results:No relationship was found between changes in the ratio of beneficial bacteria and changes in SOFA/APACHEⅡscores at the time of admission.The rate of good enteral nutrition was significantly higher in the increase group than in the decrease group(4/5 vs.0/5,P=0.01).Conclusions:An increase in beneficial bacteria may be significantly related to the early establishment of enteral nutrition.In the future,accumulating cases may make it possible to establish a new nutritional strategy for critically ill patients from an intestinal microbiota perspective.
文摘Background Hospitalized patients often have higher rate of vitamin D deficiency than healthy people. Vitamin D levels below normal are associated with hospital stay, increased incidence of adverse prognosis and increased mortality of a number of diseases. Whether there is a relationship between vitamin D levels and infection or sepsis in the critically ill is still unclear. This study will explore the relationship between vitamin D levels and risk of infection, assessment for disease severity, and predictor of mortality. Methods To evaluate the value of vitamin D in intensive care unit （ICU） cases to sepsis, severity and prognosis assessment, high performance liquid chromatography and tandem mass spectrometry were used to measure the concentrations of vitamin D in sera of critically ill patients. The serum samples were drawn within the first 24 hours of ICU admission. Results The study included 206 people, 50 healthy controls, 51 ICU control patients and 105 ICU diagnosed with sepsis. Critically ill ICU patients （ICU sepsis and ICU control group） had lower vitamin D concentration than normal people, but septic patients showed no significant reduction of vitamin D concentration when compared with critically ill patients with no positive etiological evidence. For assessment of disease severity, there were very low negative correlations between APACHE II, SAPS II and SOFA scores and vitamin D level. Additionally, patients of different 25-（OH）D levels showed no difference whether in terms of 28-day survival （χ2=1.78, P=0.776） or 90-day survival （χ2=4.12, P=0.369）. Multivariate Logistic regression demonstrated that APECHE II and SAPS II scores were independent risk factors to deaths caused by sepsis. Conclusion Clinically, serum concentration of vitamin D is not an indicator for diagnosis and assessment in critically ill patients （ClinicalTrial.gov identifier NCT01636232）.

文摘Background:Despite the recent advances in treatments for rheumatoid arthritis (RA), there are still unmet needs in disease outcomes. This study aimed to analyze the satisfaction with drug therapies for RA according to the levels of disease severity (patientassessed) and proportions of treatment cost to household income.Methods:This was a subgroup study of a cross-sectional study in patients with RA and their physicians. The patients were subdivided into different subgroups based on their self-assessed severity of RA and on the proportions of treatment cost to household income (<10%, 10-30%, 31-50%, and >50%). The Treatment Satisfaction Questionnaire for Medication version II was used to assess patients’ treatment satisfaction.Results:When considering all medications, effectiveness, convenience, and global satisfaction scores were lower in the severe and moderate RA subgroups than those in the mild and extremely mild RA subgroups (all P < 0.001). Effectiveness, side effects, and convenience scores were higher in the <10% subgroup compared to those in the >50% subgroup (all P < 0.05). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup ( F = 13.183, P = 0.004). For biological diseasemodifying anti-rheumatic drugs, effectiveness and convenience scores were lower in the severe RA subgroup than those in the extremely mild RA subgroup (both P < 0.05). Convenience score was higher in the <10% subgroup compared to that in the 31% to 50% and >50% subgroups ( F = 12.646, P = 0.005). Global satisfaction score was higher in the <10% subgroup than that in the 31% to 50% subgroup ( F = 8.794, P = 0.032). Conclusion:Higher disease severity and higher financial burden were associated with lower patient satisfaction.

文摘Background: Sleep disorders are common but under-researched symptoms in patients with multiple system atrophy (MSA). We investigated the frequency and factors associated with sleep-related symptoms in patients with MSA and the impact of sleep disturbances on disease severity.Methods: This cross-sectional study involved 165 patients with MSA. Three sleep-related symptoms, namely Parkinson’s disease (PD)-related sleep problems (PD-SP), excessive daytime sleepiness (EDS), and rapid eye movement sleep behavior disorder (RBD), were evaluated using the PD Sleep Scale-2 (PDSS-2), Epworth Sleepiness Scale (ESS), and RBD Screening Questionnaire (RBDSQ), respectively. Disease severity was evaluated using the Unified MSA Rating Scale (UMSARS).Results: The frequency of PD-SP (PDSS-2 score of ≥18), EDS (ESS score of ≥10), and RBD (RBDSQ score of ≥5) in patients with MSA was 18.8%, 27.3%, and 49.7%, respectively. The frequency of coexistence of all three sleep-related symptoms was 7.3%. Compared with the cerebellar subtype of MSA (MSA-C), the parkinsonism subtype of MSA (MSA-P) was associated with a higher frequency of PD-SP and EDS, but not of RBD. Binary logistic regression revealed that the MSA-P subtype, a higher total UMSARS score, and anxiety were associated with PD-SP;that male sex, a higher total UMSARS score, the MSA-P subtype, and fatigue were associated with EDS;and that male sex, a higher total UMSARS score, and autonomic onset were associated with RBD in patients with MSA. Stepwise linear regression showed that the number of sleep-related symptoms (PD-SP, EDS, and RBD), disease duration, depression, fatigue, and total Montreal Cognitive Assessment score were predictors of disease severity in patients with MSA.Conclusions: Sleep-related disorders were associated with both MSA subtypes and the severity of disease in patients with MSA, indicating that sleep disorders may reflect the distribution and degree of dopaminergic/non-dopaminergic neuron degeneration in MSA.
文摘Background: The COVID-19 pandemic emerged unexpectedly, impacting millions worldwide and, though waning in many regions, remains a significant concern. This study focused on understanding COVID-19’s clinical presentation, disease progression, and outcomes among hospitalized pediatric patients. Additionally, it sought to investigate the impact of concurrent chronic medical conditions on disease severity. Methods: Conducted retrospectively between September 2020 and December 2021, this study observed pediatric patients (below 18 years) hospitalized with confirmed COVID-19 at an Irbid, Jordan tertiary healthcare center. Patients meeting inclusion criteria, including a positive nasal swab PCR test and hospitalization need, were analyzed. Epidemiological and clinical data were collected and segregated into two groups (A and B) based on the presence of chronic conditions. Comparative analysis encompassed presentation, disease trajectory, and outcomes between these groups. Results: Among 451 tested positive patients, 112 were included in the study. Significant differences emerged between the two pediatric groups hospitalized for COVID-19. Those with concurrent chronic illnesses exhibited heightened symptom severity—fever, dyspnea, fatigue—and a higher incidence of abnormal chest radiographs, often requiring intensive care and experiencing elevated mortality rates. Conclusion: This study underscores the criticality of prioritizing COVID-19 management strategies for pediatric patients with pre-existing chronic medical conditions. The findings highlight the increased vulnerability and poorer outcomes experienced by this subgroup, emphasizing the necessity for tailored interventions and focused care approaches.
文摘BACKGROUND： Aspirin can decrease the incidence risk of high-risk crowdgroup of cerebral infarction, but there are still controversy if it might decrease the degree of disease in degree of patients with acute cerebral infarction. OBJECTIVE： To observe the effect of lower dose of aspirin during taking for a long time on disease degree of disease following onset of acute cerebral infarction. DESIGN： Grouping according to the admission time and 1：1 paired observation.SETTING ： Department of Neurology, Qilu Hospital of Shandong University.PARTICIPANTS ： The participants in present study were 321 patients with acute cerebral infarction who received treatments in the Department of Neurology, Qilu Hospital of Shandong University from January 1999 to June 2000.

Two groups of patients had the same basic conditions except for taking aspirin or not before. ②The matched pairs were made between 50 cases selected from aspirin-treated group and 50 cases from non-aspirin-treated groups according to age, gender, and other stroke risk factors. ③ Evaluation： Degree of disease after onset was evaluated by means of Acute Cerebral Infarction Clinical Neurologic Impairment Degree Scoring Standard of Carotid Artery System. MAIN OUTCOME MEASURES： Acute Cerebral Infarction Clinical Neurologic Impairment Degree Scoring Standard of Carotid Artery System. RESULTS ： All 321 patients entered the stage of analysis with no loss in the midway. ① The symptom following onset of acute cerebral infarction was evaluated with clinical neurologic impairment scoring criteria, there were no significant differences between aspirin group and blank control group [（17.39±9.90） vs （16.22 ± 9.98） （t=1.025, P〉 0.05）]. ② No significant differences were found in 1：1 matched pairs of 100 cases from aspirin group and blank control group （t=1.74, P 〉 0.05）. CONCLUSION ： Taking a lower dose of aspirin during long time may not decrease the degree of disease following onset of acute cerebral infarction.
文摘Respiratory viral co-infections present significant challenges in clinical settings due to their impact on disease severity and patient outcomes.Current diagnostic methods often miss these co-infections,complicating the epidemiology and management of these cases.Research,primarily conducted in vitro and in vivo,suggests that co-infections can lead to more severe illnesses,increased hospitalization rates,and greater healthcare utilization,especially in high-risk groups such as children,the elderly,and immunocompromised individuals.Common coinfection patterns,risk factors,and their impact on disease dynamics highlight the need for advanced diagnostic techniques and tailored therapeutic strategies.Understanding the virological interactions and immune response modulation during co-infections is crucial for developing effective public health interventions and improving patient outcomes.Future research should focus on the molecular mechanisms of co-infection and the development of specific therapies to mitigate the adverse effects of these complex infections.
文摘This study aimed to explore the characteristics of serum metabolomics in patients with non-alcoholic fatty liver disease(NAFLD)and its correlation with the severity of the disease based on gas chromatography-mass spectrometry(GC-MS).A total of 200 NAFLD patients and 100 healthy controls were included.Serum samples were collected and analyzed by GC-MS,and the data were processed using multivariate statistical methods such as principal component analysis(PCA)and partial least squares-discriminant analysis(PLS-DA).The results showed that a total of 50 differential metabolites were identified,including fatty acids such as palmitic acid and oleic acid,amino acids such as glutamine and glycine,and organic acids such as lactate and citrate.The level of palmitic acid was increased while the level of glutamine was decreased in the patient group.Moreover,some of the metabolites were significantly correlated with the severity of the disease.For example,palmitic acid was positively correlated with the severity of NAFLD,while glutamine was negatively correlated.This study indicates that serum metabolomics can effectively distinguish NAFLD patients from healthy individuals,and the characteristic metabolites play a crucial role in the pathogenesis of NAFLD.Furthermore,they have the potential to serve as biomarkers for disease diagnosis and monitoring,providing a basis for a deeper understanding of NAFLD and the development of novel diagnostic and therapeutic strategies.
文摘BACKGROUND: It has been suggested that addition of obesity score to the APACHE-Ⅱ system can lead to more accurate prediction of severity of acute pancreatitis. However there is scanty information on the usefulness of the combined APACHE-O scoring system in Asian patients. This study aimed to compare the accuracy of Ranson, APACHE-Ⅱ and APACHE-O systems in assessing severity of acute pancreatitis in a local Chinese population. METHODS: One hundred and one consecutive patients with acute pancreatitis were prospectively studied. Body mass index (BMI) was measured on admission. Ranson score, APACHE-Ⅱ and APACHE-O scores were recorded on admission and at 48 hours. By adopting the cut-off levels and definitions advocated in the Atlanta consensus for severe disease, the diagnostic accuracy of the three scoring systems was compared by the area under the curve (AUC) under the receiver operator characteristic curve. RESULTS: Of the 101 patients, 12 (11.9%) patients suffered from severe pancreatitis. Obesity was uncommon and only two patients (2.0%) had BMI >30. Eighty-two (81.2%) patients were normal weight (BMI≤25) whereas 17 (16.8%) were overweight ( BMI 25-30 ). Overweight or obesity (BMI >25) was not associated with severe pancreatitis (P= 0.40). The AUC for admission scores of Ranson, APACHE-Ⅱ, and APACHE-O systems was 0. 549, 0. 904 and 0. 904, respectively. The AUC for 48-hour scores of Ranson, APACHE-Ⅱ and APACHE-O systems was 0.808, 0.955 and 0.951, respectively. CONCLUSIONS: The APACHE-Ⅱ scoring system is more accurate than the Ranson scoring system of the prediction of severity in acute pancreatitis. Addition of obesity score does not significantly improve the predictive accuracy of the APACHE-Ⅱ system in our local population with a low prevalence of obesity.
