ABSTRACT
Objective@#The purpose of this nationwide age- and sex- matched longitudinal study was to determine the pyogenic spondylitis (PS) increases the incidence of ischemic stroke (IS) in Korea. @*Methods@#From the National Health Insurance Service (NHIS), we collected the patient data for the period from January 1, 2004 to December 31, 2015. PS was classified according to the International Classification of Disease codes M46.2-M46.8, M49.2, and M49.3. By using a 1:5 age- and sex- stratified matching, a total of 628 patients and 3140 control subjects were included in the study. The IS incidence rates in PS and control group was calculated by using the Kaplan-Meier method. The outcome of hazard ratio of IS was estimated by Cox proportional hazards regression analyses. This study did not exclude PS as a result of postoperative complications. @*Results@#According to the study, 51 patients (8.12%) in the PS group and 201 patients (6.4%) in the control group experienced IS. The adjusted hazard ratio of IS in the PS group was 3.419 (95% CI: 2.473-4.729) after adjusting individual medical condition and demographics. Following the results of subgroup analysis, the risk ratio of IS was greater in most of the subgroup categories (male, female, age 65, non-diabetic, hypertensive, non-hypertensive, dyslipidemic and non-dyslipidemic subgroup). However, the risk of IS did not differ significantly in diabetic subgroup (95% CI: 0.953-4.360). @*Conclusions@#The risk rate of IS increased in patient with pyogenic spondylitis.
ABSTRACT
Objective@#: The goal of the following statewide age and gender-coordinated cohort study in Korea is to find out if there is a link between acute myocardial infarction (AMI) and Parkinson’s disease (PD). @*Methods@#: Utilizing the National Health Insurance Sharing Service cohort, patient data were collected. Six thousand four hundred seventy-five individuals with PD were distinguished by utilizing the International Classification of Diseases 10 code G20 and have enrolled in the PD group. The number of participants decreased to 5259 after excluding 1039 patients who were hospitalized less than one time or who visited an outpatient clinic less than twice. Then, 26295 individuals were selected as part of the control group after case control matching was conducted through 1 : 5 age- and gender-coordinated matching. The Cox proportional hazard regression analysis and Kaplan-Meier method were utilized to analyze the likelihood of AMI in PD. @*Results@#: After controlling for age and gender, the hazard ratio of AMI in the PD group was 3.603 (95% confidence interval [CI], 2.837–4.577). After that, the following hazard ratio of AMI in the PD group was modified against for co-morbid medical disorders, resulting in 3.551 (95% CI, 2.795–4.511). According to a subgroup analysis, in males and females aged <65 and aged ≥65 and in the non-diabetes and diabetes, hypertension and non-hypertension, dyslipidemia and non-dyslipidemia subgroups, the AMI incidence rates were dramatically higher in the PD group compared to that of the control. @*Conclusion@#: Individuals with PD have a greater chance of AMI, according to this cross-national study.
ABSTRACT
Objective@#The aim of this nationwide age- and sex- matched longitudinal follow up study is to determine the risk of Parkinson’s disease (PD) associated with ischemic stroke in Korea. @*Methods@#Patient data were collected from the National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS). PD was identified using the International Classification of Diseases (ICD) 10-CM code G 20. In total, 6,475 patients were enrolled in the PD group from the NHISS. After subtracting 1,039 patients who underwent hospitalization less than once or those who visited an outpatient clinic less than two times, 5,259 patients who were diagnosed after January 1, 2004 ultimately participated in this study.

ABSTRACT
Objective To analyze the acoustic features of patients with Parkinson's disease (PD),and to explore the correlation between the acoustic features and the severity and course of disease.Methods Fifty-two patients with PD from the Tongji Hospital Affiliated to Tongji Medical University and the Ninth People's Hospital Affiliated to the Medical College of Shanghai Jiaotong University from August to December 2015 were enrolled into this study.Thirty-two age-matched healthy people served as control group.PD patients were tested with Unified Parkinson's Disease Rating Scale (UPDRS) and Hoehn-Yahr (H-Y) staging.And all the patients were tested with Mini-Mental State Examiantion (MMSE) and Voice Handicap Index (VHI).The voice samples of all subjects were collected and the frequency perturbation (jitter),amplitude perturbation (shimmer),and harmonic-to-noise ratio (NHR) were analyzed using a vocal assessment.Fundamental frequency (F0),standard deviation of fundamental frequency (SDF0) and formant ratio (F2i/F2u) were analyzed using a real-time speech measuring instrument.The acoustic parameters of the two groups were compared and the correlation between the parameters of the patients and the disease and course of disease was analyzed.Results Subjective assessment using VHI showed a total of 24 VHI abnormalities (46％) in the PD group,including 13 males (54％),11 females (46％).No VHI abnormalities were found in the control group.Among the parameters analyzed by objective acoustic method,compared with the control group (female/a/1.43(1.19,1.92),/i/3.39(1.49,9.85),/u/1.46(1.23,3.85);male/a/1.06(0.92,1.89),/u/1.30(1.07,1.64)),the SDF0 of the three vowels of the female patients in the PD group (/a/2.99(1.81,4.12),Z=5.429,P＜0.01;/i/10.89(5.47,22.20),Z=8.487,P＜0.01;/u/5.16(3.75,7.80),Z=7.138,P＜0.01) and /a/ and /u/ of the male patients in the PD group (/a/2.16(1.73,2.94),Z=4.858,P=0.002;/u/3.70(2.41,5.43),Z=7.664,P＜0.01) were significantly increased,and the F2i/F2u in the PD group (male 1.96±0.84,female 1.81± 1.14) was lower than that in the control group (male 3.48±0.70,female 4.14± 1.08),and the difference was statistically significant (t=-6.669,-6.844,P＜0.01).There were no statistically significant differences in frequency perturbation,amplitude perturbation,harmonic noise ratio and fundamental frequency.Only the fundamental frequency standard deviation of the sound parameters used in the study was correlated with the disease course of PD patients.After the severity of the disease was assessed by H-Y staging,the frequency perturbation (jitter),amplitude perturbation (shimmer) in the middle and late stage patients were higher than those in the early stage patients,and the difference of frequency perturbation in the three vowels was statistically significant,and the difference of amplitude perturbation in the vowels/i/and/u/was statistically significant.No correlation was found between the acoustic parameters and UPDRS score.Conclusions Consonance disorders are common in PD patients,and the changes in acoustic parameters are mainly manifested as the increase in the SDF0 and the decrease in the F2i/F2u.Acoustic parameters can be used as an effective indicator to evaluate the condition and course of PD patients,and further language tasks need to be added to clarify.
