ABSTRACT
Parkinson's disease(PD)and multiple system atrophy(MSA)are two common Parkinsonian syndromes with overlapping clinical manifestations, and clinical differential diagnosis is difficult.Lower urinary tract symptoms are one of the common non-motor symptoms of the two diseases.The incidence of lower urinary tract symptoms in MSA is higher, the onset is earlier, and the micturition period is more prominent.The urinary dysfunction in patients with PD is mainly caused by the central mechanism, leading to overactive bladder.MSA has more extensive lesions with both central and peripheral involvement, leading to overactive bladder and severe voiding dysfunction.Urodynamics can be used to evaluate bladder and urethral function.MSA has more prominent weak detrusor activity, residual urine volume, and early changes of urethral sphincter.The treatment of lower urinary tract symptoms in patients with PD is mainly based on anticholinergic drugs to improve overactive bladder, while in MSA patients with increased residual urine volume, intermittent catheterization is the main method to improve lower urinary tract symptoms.This article reviewed the epidemiology, pathological mechanism, urodynamics and treatment of lower urinary tract symptoms of the two diseases, so as to assist in their differential diagnosis and treatment.
ABSTRACT
Objective:To explore the difference of clinical characteristics between senile Parkinson's disease(PD)with depression and unipolar depression.Methods:From March 2019 to March 2020, 53 patients with Parkinson's disease depression and 57 patients with unipolar depression who were admitted to the neurology department of Beijing Hospital were continuously collected.The gender, age and education level of the patients were recorded.The course of disease and other general data of the patients with Parkinson's disease were also recorded.Depression and anxiety of the patients were evaluated by Beck Depression Inventory(BDI)and Generalized Anxiety Disorder Scale(GAD-7). Quality of life of patients with Parkinson's disease was evaluated by 8-item Parkinson's disease questionnaire(PDQ-8). Differences in the assessment results and quality of life scores between the two groups were analyzed.Results:The incidence of depression comorbid with anxiety in elderly PD patients was 52.8%(28/53), lower than that in elderly unipolar depression patients comorbid with anxiety [84.2%(48/57)]( χ2=12.664, P<0.001). The scores of activity inhibition [(1.8±0.8)points]and hyposexuality [(0.4±1.0)points]in elderly PD patients with comorbid depression were higher than that in patients with unipolar depression [(1.1±0.8)points, (0.0±0.0)points]( t=4.399, 2.942, P<0.001, =0.005). Moreover, the incidence of activity inhibition(98.1%)and hyposexuality(15.1%)in PD patients with comorbid depression was higher than that in patients with unipolar depression(78.9%, 0.0%)( χ2=9.680, 9.279, both P=0.002). The scores of self-blame [(1.0±0.8)points]and pain [(1.0±0.8)points]in elderly patients with unipolar depression were higher than those in PD patients with comorbid depression [(0.5±0.7)points, (0.9±0.7)points]( t=-3.902, -2.486, P<0.001, =0.014). Moreover, the incidence of self-blame(66.7%), irritability(78.9%)and image distortion(56.1%)in elderly patients with unipolar depression was higher than that in PD patients(35.8%, 56.6%, 35.8%)( χ2=10.447, 6.320, 4.547, P=0.001, 0.012, 0.033). The scores of PDQ-8 in PD patients with comorbid depression and anxiety [14.8(10.8, 19.0)points]( Z=-3.544, P<0.001)were higher than those in PD patients with depression only [7.0(4.8, 11.0)points]. Conclusions:The focus of depression in elderly PD patients is different from that in elderly unipolar depression patients.Elderly patients with unipolar depression are more likely to be comorbid with anxiety.Depression reduces the quality of life in PD patients, and the comorbidity of anxiety further reduces the overall quality of life in PD patients with depression.
ABSTRACT
Objective:To investigate the characteristics and clinical related factors of Parkinson′s disease (PD) patients with subjective cognitive decline (SCD).Methods:Ninety-nine PD patients with normal cognitive function enrolled in Beijing Hospital from January to December 2018 were collected for the study. Patients with PD were divided into groups with ( n=57) and without ( n=42) SCD using the first question in Part 1 of the Unified Parkinson′s Disease Rating Scale (UPDRS). All patients were assessed by Montreal Cognitive Assessment (MoCA), modified Hoehn-Yahr grading, UPDRS, Hamilton Rating Scale for Depression (HAMD), Hamilton Rating Scale for Anxiety (HAMA), Parkinson′s Disease Sleep Scale, Ability of Daily Living Scale and 39-item Parkinson′s Disease Questionnaire (PDQ-39). Levodopa equivalent dose conversion was performed for patients taking anti-PD drugs. Patients′ self-reported years of formal education were collected. Results:The proportion of PD with SCD in this group was 57.58% (57/99). There were statistically significant differences in MoCA [28.00 (27.00, 29.00) vs 28.00 (27.00, 29.00) ,Z=-2.28, P=0.023], HAMD [6.00 (5.00, 8.50) vs 5.00 (2.00, 8.00), Z=-2.23, P=0.026], HAMA [7.00 (6.00, 11.00) vs 6.00 (3.00, 8.25) , Z=-2.70, P=0.007], PDQ-39-emotional health [2.00 (0, 5.00) vs 1.00 (0, 3.00), Z=-2.03, P=0.042] and PDQ-39-cognitive scores [4.00 (2.00, 5.00) vs 2.00 (0, 4.00), Z=-3.42, P=0.001] between PD with and without SCD groups. SCD was correlated with MoCA ( r=-0.23, P=0.022), HAMD ( r=0.23, P=0.025) and HAMA ( r=0.27, P=0.006) scores to varying degrees. When controlling for HAMD and HAMA scores, the correlation between SCD and MoCA scores ( r′=-0.18, P=0.084) was no longer existed. Conclusions:SCD is common in PD patients with normal cognitive function and is associated with poorer cognitive performance and more severe symptoms of depression and anxiety. In this group of patients, the relationship between SCD and affective symptoms may be greater than that of objective overall cognitive function, which is worthy of further studies.
ABSTRACT
Objective:To investigate the grey matter alterations of Parkinson′s disease (PD) patients with and without sleep disorders, and to explore the relationship between different sleep-related problems and clinical variables as well as grey matter volume (GMV) in PD.Methods:Forty-six PD patients and 38 healthy controls (HCs) were recruited from January 2018 to December 2021 in the Department of Neurology, Beijing Hospital. PD patients were divided into PD with sleep disorders (PD-S, n=26) and PD without sleep disorders (PD-nS, n=20) subgroups (cutoff points of 82 for Parkinson′s Disease Sleep Scale or less than 5 for each item was considered as an indicator of substantial sleep disorder). The Mini-Mental State Examination (MMSE), the third part of the Unified Parkinson′s Disease Rating Scale (UPDRS-Ⅲ), Hamilton Rating Scale for Anxiety (HAMA), Hamilton Rating Scale for Depression (HAMD), Non-Motor Symptoms Questionnaire (NMSQ), and Parkinson′s Disease Questionnaire-39 (PDQ-39) were used to evaluate cognitive function, motor symptoms, anxious and depressive symptoms, non-motor symptoms, and the quality of life of the patients. Optimized voxel-based morphometry was applied to the magnetic resonance imaging brain images in all participants,and multiple linear regression analysis was used to test the correlation between GMV and sleep quality in patients with PD. Results:Compared with the HCs, PD-nS patients showed decreased GMV in bilateral limbic lobe, parahippocampal gyrus, amygdala, cingulate gyrus, hippocampus, right cerebellum, bilateral frontotemporal lobe, bilateral occipital lobe and the left parietal lobe. PD-S group exhibited reduced GMV in bilateral limbic lobe, parahippocampal gyrus, amygdala, right cerebellum, bilateral frontotemporal lobe and bilateral parietal-occipital lobe, compared to the HCs. Compared with PD-nS, PD-S patients revealed higher depressive (HAMD score: 12.19±5.59 vs 6.95±3.19, t=-4.01, P<0.001), anxious (HAMA score: 12.04±5.32 vs 7.25±4.68, t=-3.18, P=0.003), and non-motor symptoms scores (NMSQ score: 12.92±5.18 vs 9.90±4.10, t=-2.14, P=0.038), poorer quality of life (PDQ-39 score: 35.31±22.01 vs 22.40±9.00, t=-2.71, P=0.010), and reduced GMV in the left insula, frontal, and parietal lobe ( P<0.001, uncorrected, cluster>100). There was a marked relationship between sleep quality and the reduced GMV of the right medial temporal gyrus (β=0.006, 95% CI 0.002-0.010, P=0.003), left middle frontal gyrus (β=0.006, 95% CI 0.002-0.010, P=0.002), the right cerebellum (β=0.014, 95% CI 0.005-0.023, P=0.003), and the right medial occipital gyrus (β=0.017, 95% CI 0.011-0.024, P<0.001). Significant grey matter changes were associated with nocturnal restlessness, mainly within the left limbic lobe, bilateral occipital lobe, the right cerebellum, and parietal lobe (β=0.008, 95% CI 0.006-0.010, P<0.001). Furthermore, nocturia in PD was related to certain grey matter atrophy, including bilateral limbic lobe, the right inferior parietal gyrus, and bilateral frontal lobe (β=0.010, 95% CI 0.008-0.013, P<0.001). The symptom of daytime dozing was correlated with GMV reduction in the right occipital lobe, the left temporal lobe (β=0.014, 95% CI 0.010-0.019, P<0.001). There were also several compensatory brain regions, including bilateral frontal lobe, the left limbic lobe and cingulate ( P<0.001, uncorrected, cluster>60). Conclusions:Sleep disturbance is common in PD, which is related to the anxious and depressive symptoms, non-motor symptoms, and the quality of life. PD patients with different sleep disorders show grey matter alterations in severeal brain regions, which are associated with sleep quality, nocturnal restlessness, psychosis, and daytime dozing.
ABSTRACT
Clinical data of 67 patients with recurrent inguinal hernia and chronic pain after anterior repair of transversalis fascia who underwent Kugel procedure through the primary incision in Wenling First People′s Hospital between June 2015 and January 2019 were retrospectively reviewed. During the operation the surrounding scar tissue and previous mesh or plug were removed, the transversalis fascia was separated and the patch was placed to overlay myopectineal orifice. The mean operative time was 57 min (51-85 min).The peritoneum rupture occurred during the operation in 6 cases (8.9%), and seroma was developed in 5 patients(7.5%). After a mean 18 months of follow-up, no recurrence occurred in all patients. Three months after operation, the mild, moderate or severe pain in all 67 patients were all improved remarkably with a total pain relief rate of 92.5%. The results show that Kugel procedure through the primary incision is safe and effective in treatment of recurrent inguinal hernia with chronic pain after anterior repair of transversalis fascia.
ABSTRACT
Objective:To investigate the accurrence and related factors of depression in patients with parkinson's disease (PD).Methods:One hundred PD patients with Parkinson′s disease (PD) were enrolled in Department of Neurology in Beijing Hospital from March to June 2019. The depressive mood, sleep status and health-related quality of life of PD patients were evaluated by Beck Depression Scale (BDI), Parkinson′s Disease Sleep Scale 2 (PDSS-2), and 8 items of Parkinson′s Disease Questionnaire (PDQ-8). Spearman correlation analysis and multivariate regression analysis were used to analyze the related factors of PD depression. Nonparametric test was used to analyze the differences between different sleep disorder domains in PD patients with depression.Results:The total score of BDI in 100 PD patients ranged from 0 to 44, with an average of 9.9±8.6 points; the total score of PDSS-2 ranged from 0 to 43, with an average of 12.0±9.2; the total scores of PDQ-8 ranged from 0 to 24, with an average of 6.4±6.0 points. The detection rate of depression in 100 PD patients was 42.0% (42/100), and the total BDI score of 22 patients with mild depression ranged from 10 to 15 with an average of 13.0±1.9; the total BDI score of 14 patients with moderate depression ranged from 16 to 25, with an average of 19.1±3.0; the total BDI score of 6 patients with major depression ranged from 28 to 44 points, with an average of 33.3±6.4. The depression in PD patients was positively correlated with PDQ-8 score ( t=8.908, P<0.01) and PDSS-2 score ( t=2.286, P=0.02); and 85.7% (36/42) of PD patients with depression had sleep disturbance. The score of sleep disturbance domain of PD patients with depression (9.8±3.9) was higher than that of nocturnal motor symptom domain (4.8±4.5) and nocturnal PD non-motor symptom domain (4.1±3.3) ( P<0.01). The scores of emotional health, relationship with loved ones, attention, communication ability dimensions of PDQ-8 were positively correlated with PD depression ( P<0.05). Conclusion:Depression is a common non-motor symptom of PD patients; and PD patients with depression suffer from reduced quality of life and are more prone to sleep disorders.
ABSTRACT
Objective:To investigate the clinical features and associated chronic pain in corticobasal syndrome (CBS).Methods:Clinical data of 8 patients diagnosed as probable CBS or possible CBS admitted to Beijing Hospital during January 2010 to June 2020 were retrospectively analyzed. The clinical information included sex, age, course of disease, chief complaint, neurological examination, blood biochemistry, tumor marker, infection and other laboratory tests; the neuropsychological evaluation included Mini-Mental State Examination (MMSE) scale and Hamilton Depression Scale (HAMD); the imaging studies included cranial magnetic resonance imaging (MRI) and/or 18F-Fluorodeoxyglucose positron emission tomography ( 18F-FDG PET). Results:The main clinical manifestations were asymmetrical movement disorders, including rigidity, tremor, myoclonus and abnormalities in posture and gait. Patients showed poor response to levodopa treatment. Among 8 patients, 7 had apraxia, 5 patients had alien hand, and 5 patients had various degrees of cognitive dysfunction. The cranial MRI demonstrated mild cerebral atrophy which was slightly more severe in the contralateral side of the initially affected limb in 7 of the 8 patients. The 18F-FDG PET scan revealed asymmetric decreased metabolism in the frontal, parietal, temporal, and occipital lobe, as well as in basal ganglia, which was more severe in the contralateral side of the initially affected limb in 5 of the 8 patients. Six of the 8 patients were associated with pain, including dystonic pain in 3 patients, neuropathic pain in 1 patient, musculoskeletal pain in 1 patient, and unexplained pain in 1 patient. Pain was the onset symptom in 1 patient and pain was relieved by taking levodopa in another patient. Conclusions:CBS is characterized by asymmetric dyskinesia and cognitive impairment, and often associated with apraxia, cortical sensory deficits, and alien limb. The MRI and PET are helpful for CBS diagnosis. Pain may be one of the common non-motor symptoms in CBS.
ABSTRACT
A total of 521 patients underwent laparoscopic radical gastrectomy from January 2013 to January 2020 in the First People′s Hospital of Wenling. In 242 cases the splenomental fold was severed before dissecting the left half of omentum or spleen (pretreatment group), and in 279 cases the splenomental fold was not severed priorly (routine group). For pretreatment group the introoperative splenic injury occurred in 4 cases (1.65%), including 3 cases (1.24%) with class Ⅰ injury and 1 case (0.41%) with class Ⅱ injury; while for routine group splenic injury occurred in 24 cases (8.60%), including 22 cases (7.89%) with class Ⅰ injury and 2 cases (0.72%) with class Ⅱ injury, and the rupture of splenic capsule caused by tracting splenomental fold occurred in 19 cases(6.81%). There were significant differences in total number of splenic injuries, splenic injuries with class Ⅰ and rupture of splenic capsule caused by tracting splenomental fold between two groups ( P<0.05). The operation time of 28 cases with splenic injuries was (185±89) min, which was longer than that in 493 cases without splenic injuries [(172±95) min, P<0.05]. The results show that rupture of splenic capsule by tracting splenomental fold is main cause of splenic injury in laparoscopic radical gastrectomy and most of them are class Ⅰ injuries. To sever the splenomental fold priorly can reduce the incidence of iatrogenic splenic injury.
ABSTRACT
The iatrogenic splenic injuries occurred in 49 patients who underwent abdominal surgery from January 2005 to January 2020; including grade I injury in 40 cases and grade Ⅱ injury in 9 patients. The normal saline-soaked gauze was placed on the wound surface of the injured spleen, then the high-frequency electric coagulator was employed for hemostasis. The bleeding was successfully stopped and the spleens were preserved without postoperative complications in all cases. The results show that moist electrothermal coagulation can be effectively and safely applied in treatment of grade I and grade Ⅱ injury iatrogenic splenic injuries, and no special equipment required.
ABSTRACT
@#Objective To explore the value of transthoracic echocardiography (TTE) to monitor and evaluate aortic insufficiency (AI) within one year after the implantation of the left ventricular assist device (LVAD). Methods We retrospectively collected and analyzed the TTE data of 12 patients who received LVAD implantation from 2018 to 2020 in our hospital. All patients were males, with an average age of 43.3±8.6 years. We analyzed temporal changes in the aortic annulus (AA), aortic sinus (AoS), ascending aorta (AAo), the severity of AI and the opening of aortic valve before operation and 1 month, 3 months, 6 months and 12 months after LVAD implantation. Results All 12 patients survived within 1 year after LVAD implantation. One patient was bridged to heart transplantation 6 months after implantation, and two patients did not receive TTE after 3 and 6 months. Compared to pre-implantation, AoS increased at 1 month after implantation (31.58±5.09 mm vs. 33.83±4.69 mm). The inner diameters of AA, AoS and AAo increased at 3, 6 and 12 months after LVAD implantation compared to pre-implantation (P<0.05), but all were within the normal range except for one patient whose AoS slightly increased before operation. After LVAD pump speed was adjusted, the opening of aortic valve improved. The severity of AI increased at 6 and 12 months after LVAD implantation compared to pre-implantation, and increased at 12 months compared to 6 months after LVAD implantation (P<0.05). Conclusion TTE can evaluate aortic regurgitation before and after LVAD implantation and monitor the optimization and adjustment of LVAD pump function, which has a positive impact on the prognosis after LVAD implantation.
ABSTRACT
The Chinese guidelines for the treatment of Parkinson′s disease (fourth edition) inherits the essence of the third edition, confirming the therapeutic principles of the third edition, which emphasizes that “Once early diagnosis is made， treatment should be started as soon as possible to grasp the opportunity of disease modification”. It also proposes the concept of “not deliberately delay the use of levodopa”, and pays more attention to non-motor symptoms. The importance of multi-disciplinary team in the overall and whole-process management of Parkinson′s disease is emphasized. According to evidence-based medicine and recommendations in recent years, and based on clinical practice, the new guideline elaborates the concept in depth, including classical treatment, drug use, update of treatment concept, new technology and new method. Moreover, it updates initial and subsequent therapy according to the clinical characteristics, enhances practicality of the guideline, and plays a critical role in further standardizing and improving the level of the overall treatment of Parkinson′s disease in China.
ABSTRACT
Objective:To investigate the characteristics of white matter lesions(WML)found by magnetic resonance imaging(MRI)and the relationship with clinical features in patients with Parkinson's disease(PD).Methods:This was a retrospective study by using a method of MRI T2WI-FLAIR.The WML in 87 PD patients were evaluated by using the Fazekas scale and Scheltens scale.Patients were divided into the early PD group[n=47, Hoehn-Yahr(H-Y)stage 1.0-2.0] vs.the middle-advanced PD group(n=40, H-Y stage 2.5-4.0), the non-depressed PD group(n=71) vs. the depressed PD group(n=16), the non-anxions PD group(n=62) vs.the anxions PD group(n=25). An ordinal regression model was used to investigate the correlations of WML with gender, age, Mini-Mental State Examination(MMSE)score, Unified Parkinson's disease Rating Scale-Ⅲ score(UPDRS-Ⅲ), Hamilton Rating Scale for Depression score(HAMD)and Hamilton Rating Scale for Anxiety score(HAMA). Results:Compared with the early PD group, the middle-advanced PD group showed that the WML were increased in lobe of brain(5.30±4.85 vs. 3.43±3.13, P<0.05), especially in the occipital lobe(0.48±0.99 vs. 0.11±0.31, P<0.05). There was no significant difference in the WML between the non-depressed/anxions and the depressed/anxions PD group.After being evaluated by the Scheltens scale, WML in periventricular hyperintensities(PVH)regions( OR=1.13, P<0.01), in brain lobe( OR=1.10, P<0.01)and in basal ganglia regions( OR=1.15, P<0.01)were correlated with age.WML in the brain besides the PV region were correlated with MMSE score( OR=0.68, P<0.01), especially in posterior horns( OR=0.60, P<0.01)and lateral ventricles( OR=0.68, P<0.05). WML in temporal lobe was correlated with MMSE score( OR=0.68, P<0.05). WML in brain lobe was correlated with H-Y stages( OR=2.10, P<0.05), especially in the occipital lobe( OR=3.33, P<0.05). WML in parietal lobe was associated with HAMD score( OR=1.13, P<0.05). WML in basal ganglia regions was related to diabetes( OR=6.34, P<0.05), especially in the putamen( OR=6.86, P<0.01). After being evaluated by the Fazekas scale, WML in PVH region( OR=1.16, P<0.01)and deep white matter hyperintensities( OR=1.13, P<0.01)were correlated with age.WML in PVH region were associated with MMSE score( OR=0.65, P<0.01). WML scores in PD patients had no correlation with gender, hypertension, coronary heart disease, hyperlipemia, UPDRS-Ⅲ score and HAMA score. Conclusions:The WML is present in PD patients, and it is correlated with age, diabetes, severity of disease, depression and cognitive function.

ABSTRACT
An implantable axial blood pump was designed according to the circulation assist requirement of severe heart failure patients of China. The design point was chosen at 3 L/min flow rate with 100 mm Hg pressure rise when the blood pump can provide flow rates of 2-7 L/min. The blood pump with good hemolytic and anti-thrombogenic property at widely operating range was designed by developing a structure that including the spindly rotor impeller structure and the diffuser with splitter blades and cantilevered main blades. Numerical simulation and particle image velocimetry (PIV) experiment were conducted to analyze the hydraulic, flow fields and hemolytic performance of the blood pump. The results showed that the blood pump could provide flow rates of 2-7 L/min with pressure rise of 60.0-151.3 mm Hg when the blood pump rotating from 7 000 to 11 000 r/min. After adding the splitter blades, the separation flow at the suction surface of the diffuser has been reduced efficiently. The cantilever structure changed the blade gap from shroud to hub that reduced the tangential velocity from 6.2 m/s to 4.3-1.1 m/s in blade gap. Moreover, the maximum scalar shear stress of the blood pump was 897.3 Pa, and the averaged scalar shear stress was 37.7 Pa. The hemolysis index of the blood pump was 0.168% calculated with Heuser's hemolysis model. The PIV and simulated results showed the overall agreement of flow field distribution in diffuser region. The blood damage caused by higher shear stress would be reduced by adopting the spindle rotor impeller and diffuser with splitter blades and cantilevered main blades. The blood could flow smoothly through the axial blood pump with satisfactory hydraulics performance and without separation flow.

Objective To analyze the impact of depressive symptoms on quality of life in patients with Parkinson's disease(PD)based on middle-and long-term follow-up study,and to explore predictors for the reduced quality of life in PD patients.Methods Clinical data of 80 PD patients were searched from the electronic database in our research center.Patients who had complete general information and the following data of unified Parkinson's disease rating scale(UPDRS),Hoehn and Yahr scale(HY),mini-mental state examination(MMSE),Hamilton depression rating scale(HAMD),Hamilton rating scale for anxiety(HAMA),the 39-item Parkinson's disease questionnaire(PDQ-39),etc.after one-year follow-up were included in this study.The differences in quality of life were analyzed and compared among the non-depression group (n =38),depression remission group (n =22) and depression group(n=20).A follow-up visit was conducted after four years.The disease progression and decline in quality of life were compared between the depression and non-depression groups according to the baseline value of the Hamilton Depression Rating Scale.According to the change in PDQ-39 value,cluster analysis was used to reclassify patients into fast-decline group and slow-decline group.Logistic regression analysis was used to determine independent risk factors for the decline of quality of life.Results At the end of 1 year follow-up,the quality of life was decreased in the depression group as compared with the baseline(P =0.017),and the score of PDQ-39 was higher in the depression group than in the non-depression group and depression remission group.At the end of 4-year follow-up,UPDRS total score,UPDRSⅢ score,HY stage and PDQ-39 score were increased as compared with the baseline,the quality of life decreased more significantly,and the disease progressed faster in the depression group than the other two groups(P ＜0.05).The differences in the disease course,total score of UPDRS,HY stage and HAMD score were statistically significant between the fast-decline group and slow-decline group(P =0.001,0.039,0.003 and ＜0.001,respectively).Logistic regression analysis showed that disease course (OR =1.254,P =0.020),and baseline HAMD score (OR =1.450,P =0.003) were the independent risk factors for the decline of quality of life.Conclusions The quality of life of PD patients is worse in the depression group than in the depression remission group and non-depression group.In PD patients with depressive symptoms,the illness progression is faster,and the quality of life is decreased more significantly.The disease course and depression can predict the decline of quality of life in PD patients.
ABSTRACT
Objective@#To survey the prevalence and distribution of sleep disorders in patients with Parkinson disease (PD) and to analyze the influencing factors.@*Methods@#The prevalence and distribution of sleep disorders were surveyed with Parkinson Disease Sleep Scale (PDSS) among 206 PD patients. The association of sleep disorders with age, course of disease, cognitive function, motor function, depression, and the equivalent dose of levodopa (LED) was analyzed.@*Results@#The overall PDSS score in 206 patients was (116.9±21.4). The three most frequent items of sleep disorders were the overall sleep quality(181/206, 87.9%), difficulty in maintaining sleep(160/206, 77.7%)and nocturnal enuresis(151/206, 73.3%); the three least frequent items were early awaking(87/206, 42.2%), urinary incontinence(56/206, 27.2%)and hallucination(44/206, 21.4%). The three items with the lowest average scores were nocturnal enuresis(6.9±3.1), difficulty in maintaining of sleep(7.1±2.7)and overall sleep quality(7.1±2.0); three items with the highest average scores were audiovisual illusion(9.3±1.8), incontinence caused by motion disability(9.0±2.1) and early awaking with upper and lower limb pain(8.7±2.1). PD patients were divided into group 1 [Hoehn-Yahr(H&Y) stage 1.0-1.5], group 2 (H&Y stage 2.0-2.5) and group 3 (H&Y stage 3.0-4.0). One-way analysis of variance or non-parametric test showed that there were significant differences in the course of disease(F=21.91, P=0.00), total score and the subscale scores of Unified Parkinson Disease Rating Scale(UPDRS, UPDRS Ⅰ-Ⅳ) (F=90.67, χ2=12.86, F=31.20, F=60.17, χ2=24.01, all P<0.01), the Hamilton Rating Scale for Depression(HAMD) scores (χ2=11.06, P=0.00), LED (F=14.93, P=0.00) and Minimum Mental State Examination(MMSE) scores (χ2=9.81, P=0.01) among three groups. There was no significant difference in age and PDSS scores among three groups. The results showed that there were significant differences in terms of restless state and nocturnal dysphoria (F=5.12, P=0.01; F=3.27, P=0.04) between group 1 and group 3. The linear regression analysis showed that the HAMD and the LED scores had the greatest influence on PDSS score (R2=0.142, 0.196).@*Conclusion@#PD patients have a variety of sleep symptoms. The treatment of large doses of dopamine and depression contribute to the occurrence of PD sleep disorders.

ABSTRACT
Objective To analyze the clinical characteristics and related factors associated with impulse compulsive behaviors (ICBs) in Parkinson's disease (PD).Methods Two hundred and thirty-one PD outpatients were recruited from Beijing Hospital and Chinese Medicine Hospital of Pinggu District of Beijing from November 2012 to November 2015.Questionnaire for Impulse Compulsive Disorders in Parkinson's Disease (QUIP) was used to assess all subjects if they have ICBs or not.The general materials, medication utilized were recorded , and the related scales were used to evaluate PD patients.Intergroup analysis was made according to with or without ICBs.The Logistic regression analysis was adopted to analyze the relevance between incidence of ICBs and on-set age of PD, drinking tea or not, the 39-item Parkinson's Disease Questionnaire score, dosage of amantadine and dopamine agonist levodopa equivalent daily doses (DA-LEDD).Results Twenty-four cases of 231 outpatients were QUIP screening positive , and only 13 cases ( 5.63%) were diagnosed with ICBs as follows : hypersexuality in four ( 1.73%), compulsive shopping in two (0.87%), pathological gambling in one (0.43%), punding in eight(3.46%), dopamine dysregulation syndrome in two (0.87%) and with two or more ICBs in three (1.30%).Compared with non-ICBs group, ICBs group took more dopamine agonists (137.5(37.5, 175.0) mg/d vs 50.0(0, 125.0) mg/d, Z＝-2.175,P＝0.030), and had higher percentage of drinking tea (2/13 vs 3/218(1.4%),χ2＝11.369,P＝0.027).Logistic regression showed that higher dosage of dopamine agonist ( DA-LEDD≥100 mg/d,OR＝4.404, 95%CI 1.191-16.284,P＝0.026) was a risk factor for ICBs.Conclusions ICBs are not rare in Parkinson's disease, and punding is more common among the clinical phenotypes of ICBs. More dopamine agonists in PD (more than 100 mg/d) may be associated with about 4-fold increased odds of having ICBs.
ABSTRACT
Objective To investigate the prevalence of depression in Parkinson's disease ( PD) patients, analyze the clinical features of depression in PD patients , and evaluate its impact on quality of life. Methods One hundred and ninety-five PD patients and 63 normol controls were recruited in this study.The detailed clinical information was documented.Unified Parkinson's Disease Rating Scale and Hoehn-Yahr stage were used to evaluate the severity of motor function impairment in PD patients.Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Rating Scale were employed to assess the severity of depression and anxiety in PD patients.The 39-item Parkinson's Disease Questionnaire was applied to assess the quality of life.The cross-sectional data were calculated with SPSS 21.0 statistic software, and P ＜0.05 was considered statistically significant.Results The average score of HAMD was 8.74 ±5.51 in 195 PD patients.Depressive symptoms were found in 54.4%of the PD patients ( mild depression 48.7% and moderate depression 5.6%).Depression significantly impaired the quality of life in PD.Compared with PD without depression, PD with depression earned more scores in anxiety factor (4 (2, 5) vs 1(0, 2), Z＝ -8.69, P＝0.00), blocker factor (2 (1, 3) vs 0(0, 1), Z＝-7.95, P＝0.00), cognitive factor (1 (0, 2) vs 0(0, 0), Z＝-7.01, P＝0.00), sleep factor (2(1, 3) vs 0(0, 1), Z＝-6.42, P＝0.00) and despair factor (2 (1, 3) vs 1 (0, 1), Z＝-7.16, P＝0.00).There was no significant difference in day and night change (0(0, 0) vs 0(0, 0), Z＝-0.19, P＝0.85) and body weight (0(0, 0) vs 0(0, 0), Z＝-1.28, P＝0.20) between these two groups.The PD with depression obtained higher scores in total quality of life (30(22, 44) vs 14 (5, 24), Z＝-7.03, P＝0.00), motor function (6 (2, 13) vs 1 (0, 5), Z＝-3.67, P＝0.00), daily life ability (4 (1, 8) vs 1 (0, 4), Z＝-2.81, P＝0.01) , emotional health (5 (2, 11) vs 0 (0, 2), Z＝-5.82, P＝0.00), humiliation (2 (0, 5) vs 0 (0, 1), Z＝-3.10, P＝0.00), social support (0 (0, 1) vs 0 (0, 0), Z＝-2.86, P＝0.00), recognition function (4 (2, 6) vs 2 (0, 4), Z＝-2.87, P＝0.00), sociability(1(0, 3) vs 0(0, 1), Z＝-3.25, P＝0.00), and body pain (3 (1, 6) vs 1 (0, 2), Z＝-3.91, P＝0.00) than patients without depression.Conclusions Incidence of depression ( mainly mild ) in PD patients is high. Depressive symptoms significantly affect the quality of life of PD patients.
