Machine learning models to predict systemic inflammatory response syndrome after percutaneous nephrolithotomy.

OBJECTIVE: The objective of this study was to develop and evaluate the performance of machine learning models for predicting the possibility of systemic inflammatory response syndrome (SIRS) following percutaneous nephrolithotomy (PCNL). METHODS: We retrospectively reviewed the clinical data of 337 patients who received PCNL between May 2020 and June 2022. In our study, 80% of the data were used as the training set, and the remaining data were used as the testing set. Separate prediction models based on the six machine learning algorithms were created using the training set. The predictive performance of each machine learning model was determined by the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity and specificity using the testing set. We used coefficients to interpret the contribution of each variable to the predictive performance. RESULTS: Among the six machine learning algorithms, the support vector machine (SVM) delivered the best performance with accuracy of 0.868, AUC of 0.942 (95% CI 0.890-0.994) in the testing set. Further analysis using the SVM model showed that prealbumin contributed the most to the prediction of the outcome, followed by preoperative urine culture, systemic immune-inflammation (SII), neutrophil to lymphocyte ratio (NLR), staghorn stones, fibrinogen, operation time, preoperative urine white blood cell (WBC), preoperative urea nitrogen, hydronephrosis, stone burden, sex and preoperative lymphocyte count. CONCLUSION: Machine learning-based prediction models can accurately predict the possibility of SIRS after PCNL in advance by learning patient clinical data, and should be used to guide surgeons in clinical decision-making.

Prevalence and relevant factors of nocturia and its impact on sleep quality in Chinese university students.

The purpose of this study was to investigate the prevalence and relevant factors of nocturia and its impact on sleep quality in university students in Mainland China. A large-scale survey was conducted on 14,000 university students from 3 universities in Henan province, China by using an anonymous questionnaire. The questionnaire collected the information from the past six months. The relationships between the prevalence of nocturia and its relevant factors were evaluated. A total of 13,874 questionnaires were collected and 13,104 qualified for statistical analysis. A total of 659 students suffered from clinically relevant nocturia (CRN) (4.56% in male and 5.34% in female). Both univariate analysis and the logistic stepwise regression model showed that the prevalence of nocturia was significantly related to female, history of enuresis, ease of waking up, urgency, frequency and RUTI (P < 0.05). The sleep quality and the university entrance score of CRN group was significantly lower than that of control group (P < 0.05). Nocturia was common in Chinese university students and showed a negative impact on sleep and academic performance. Gender of female, history of enuresis, ease of waking up, urgency, frequency and RUTI were relevant factors for CRN.

[Vitamin A and vitamin D nutritional status among children and adolescents aged 6-17 years in Jiangsu Province during 2016-2017].

OBJECTIVE: This study aimed to investigate vitamin A and vitamin D conditions and related factors among children and adolescents aged 6-17 years in Jiangsu Province of China. METHODS: All the data were derived from China Nutrition and Health Surveillance of Children and Lactating Mothers in 2016-2017. By applying multiple stage stratified cluster random sampling method, 3244 children aged 6-17 years were selected from 12 survey sites in Jiangsu Province. Face to face interview, physical measurements and 6 mL blood sample were used to collect the general information, anthropometric information and blood nutritional indexes of the participants. Multivariate Logistic analysis was used for vitamin A and vitamin D conditions to test related factors. RESULTS: The prevalence of vitamin A deficiency and marginal deficiency was 0.8% and 15.8%, respectively.23.2% of the participants had vitamin D deficiency, 54.2% had vitamin D insufficiency and 4.8% had vitamin A insufficiency combined with vitamin D deficiency. Age group, weight levels, screen time and mother's education levels are the relevant factors of vitamin A insufficiency in children and adolescents. The related factors of vitamin D deficiency among children and adolescents are gender, age group, residence, physical activity level, screen time and mother's education levels. Gender, residence, weight levels, screen time and mother's education levels are the related factors of vitamin A insufficiency combined with vitamin D deficiency. CONCLUSION: Vitamin A insufficiency and vitamin D deficiency are at high epidemic levels among children and adolescents in Jiangsu Province in 2016-2017.

Prevalence and related factors of cognitive frailty in diabetic patients in China: a systematic review and meta-analysis.

Objective: Cognitive frailty (CF) is characterized by physical frailty and potentially reversible cognitive impairment without Alzheimer's disease and other dementias. Clarifying the prevalence and related factors of cognitive frailty can help researchers understand its epidemiological status and formulate intervention measures. This study aims to conduct a systematic review and meta-analysis of the prevalence and related factors of CF in diabetic patients in Chinas to better understand the current status of CF in diabetic patients in China and develop effective intervention measures for related factors. Methods: PubMed, Web of Science, Embase, Cochrane Library, CNKI, Weipu(VIP), WANFANG, China Biology Medicine (CBM) and DUXIU were searched to collect epidemiological data on Chinese diabetic patients. Articles published through May 29, 2023, were searched. The number of diabetes with CF and the total number of diabetes in the included studies were extracted to estimate the prevalence of diabetes with CF. For factors related to diabetes with CF, odds ratios (OR) and 95% confidence intervals (CI) were used for estimation. Results: A total of 248 records were screened, of which 18 met the inclusion criteria. The results of meta-analysis showed that the prevalence of Chinese diabetic patients with CF was 25.8% (95% CI = 19.7 to 31.9%). Subgroup analysis showed that hospital prevalence was higher than in the community and in women than in men. Combined estimates showed that depression, malnutrition, advanced age (≥70, ≥80), combined chronic diseases ≥4 and glycated hemoglobin ≥8.5 were risk factors for CF in diabetics patients in China, with regular exercise and high education level (≥ college) as protective factors. Conclusion: Cognitive frailty was common in diabetic patients in China. Such populations should be screened early and intervened with relevant factors.Systematic review registration: A systematic review of this study evaluated the registered websites as https://www.crd.york.ac.uk/PROSPERO/, CRD42023431396.

Factors related to the severity of obsessive-compulsive symptoms and their impact on suicide risk in epileptic patients.

OBJECTIVE: To explore relevant factors for the severity of obsessive-compulsive symptoms (OCSs) in adult epileptic patients and investigate whether the severity of OCSs is a mediator in the relationship between depressive/anxiety symptoms and suicide risk in epileptic patients. METHODS: This was a cross-sectional study from a hospital in Northeast China. Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Neurological Disorders Depression Inventory for Epilepsy (NDDIE), Generalized Anxiety Disorder (GAD-7), and Nurses' Global Assessment of Suicide Risk (NGASR) were used to assess the severity of OCSs, depressive symptoms, anxiety symptoms, and suicide risk in epileptic patients, respectively. The independent factors of the severity of OCSs and their mediating effects in the relationship between depressive/anxiety symptoms and suicide risk were evaluated by regression analyses and mediator models, respectively. RESULTS: NDDIE scores (ß = 0.404, p < 0.001), GAD-7 scores (ß = 0.247, p = 0.009), and polytherapy (ß = 0.119, p = 0.032) were the independent factors of Y-BOCS scores. The Y-BOCS scores partially mediated the relationship between GAD-7 scores and NGASR scores (standardized coefficients of indirect effect = 0.109, Bootstrap 95% CI = 0.024 to 0.214). Still, they did not mediate the relationship between NDDIE scores and NGASR scores (standardized coefficients of indirect effect = 0.062, Bootstrap 95% CI = -0.024 to 0.169). CONCLUSIONS: Depressive symptoms, anxiety symptoms, and polytherapy are independently associated with the severity of OCSs in epileptic patients. Depressive and anxiety symptoms mediate the effect of the severity of OCSs on suicide risk in epileptic patients completely.

Factors associated with subgroups of fatigue in maintenance hemodialysis patients: a cross-sectional study.

OBJECTIVE: This study aimed to investigate affected factors for subgroups of fatigue and the degree of fatigue in maintenance hemodialysis (MHD) patients. METHODS: This study included 120 MHD patients. Questionnaires, pre- and post-dialysis clinical data, bioimpedance spectroscopy, and ultrasound assessment were involved. RESULTS: The prevalence of fatigue in participants was 83%, including 54% of patients with fatigue worsened by dialysis, 13% with fatigue lessened by dialysis, and 16% with undifferentiated fatigue. Based on multi-nominal logistic regression analysis, age was associated with worsened fatigue by dialysis (odds ratio (OR) = 1.06, 95% confidence interval (CI) 1.01-1.11, p = 0.019), lower post-dialysis phosphorus was associated with lessened fatigue by dialysis (OR = 0.03, 95% CI 0.001-0.981, p = 0.049), and there was an increasing trend of patients experiencing undifferentiated fatigue as the extracellular water / intracellular water (E/I) level increased (p for trend = 0.020). Based on multi-ordinal logistic regression analysis, age was also a significant predictor for more severe fatigue (OR = 1.042, 95% CI 1.008-1.059, p = 0.015). CONCLUSIONS: Different subgroups of fatigue in MHD patients have different affecting factors. Older patients were prone to worsened fatigue by dialysis, patients with lower post-dialysis phosphorus were prone to lessened fatigue by dialysis, and patients with higher E/I levels were prone to undifferentiated fatigue. Meanwhile, older patients are prone to suffer from more severe fatigue. However, more in-depth studies are needed to clarify the pathogenesis of fatigue in MHD patients.

Investigations on incidence and relevant factors of allergies in 5725 urban pregnant women: a cohort study in China.

BACKGROUND: Allergic diseases are highly prevalent in the women of childbearing age. As we know, the immune system could change when pregnancy, which may affect the course of allergic diseases. Meanwhile, they also can affect the course and outcome of pregnancy. The data on incidence of allergies during pregnancy is lacking and conducting clinical trials in pregnant women was limited, therefore, we observed a prebirth cohort to supplement the relevant data and strengthen concerned research conductions. OBJECTIVE: We aim to obtain the incidence of allergies in urban pregnancy and explore the relevant factors of allergic diseases in urban pregnancy. METHODS: We design a multicenter and prospective cohort in 20 institutions above municipal level which were eligible according to the study design from 14 provinces covering all-side of China. This cohort was conducted from 13+6 weeks of gestation to 12 months postpartum and in our study, we chose the prenatal part to analyze. The outcome was developing allergies during pregnancy, which were diagnosed by clinicians according to the uniform criterion from National Health Commission. All the data was collected by electronic questionnaires through tablet computers. RESULTS: The incidence of allergic diseases in urban pregnant women was 21.0% (95%CI 20.0% ~ 22.0%). From social demography data, the history of allergies of pregnant women and their parents had statistical significance(p < 0.01); For exposure to living or working environment, house decoration for less than half a year, exposure to plush toys, disinfectants, insecticides, antihistamines, glucocorticoids, antipyretic analgesics, tocolytic agent and probiotics had statistical significance (all p < 0.05); For psychological status, self-rated depression and anxiety had statistical significance (p = 0.026;p = 0.006). CONCLUSION: The incidence of allergic diseases in urban pregnant women was similar to the former study and kept a medium-high level. The history of allergies of pregnant women and their parents, house decoration time, exposure to plush toys, disinfectants, insecticides, antihistamines, glucocorticoids, antipyretic analgesics, tocolytic agents, probiotics, self-rated depression, and anxiety were relevant factors of allergic diseases during pregnancy.

Incidence and relevant factors for seizures after spontaneous intracerebral hemorrhage: A systematic review and meta-analysis.

OBJECTIVE: To identify the incidence and relevant factors for seizures after spontaneous intracerebral hemorrhage (sICH) by performing a systematic review and meta-analysis. METHODS: We systematically searched PubMed, EMBASE, and Cochrane Library from inception to 14 August 2021 for studies investigating relevant factors associated with seizures after sICH. A meta-analysis of all included studies was performed by using Stata version 12.0 software. RESULTS: In total, 22 studies with 32,162 participants were included. The meta-analysis showed a 9.5% incidence of seizures after sICH. We identified 6 factors that increased the risk of seizures after sICH, including alcohol consumption(RR (95% CI) =1.26 (1.07, 1.48) , I2= 44.40%, p < 0.01), cortical involvement (RR (95% CI)= 3.22 (2.29, 4.53), I2= 80.00%, p <0.01), lobar location (RR (95% CI)= 2.99 (2.14, 4.18), I2= 75.40%, p < 0.01), large hematoma volume (SMD (95% CI)= 0.59 (0.17, 1.00) , I2= 95.40%, p < 0.01), hematoma evacuation (RR (95% CI)= 2.38 (1.08, 5.25), I2= 86.60%, p = 0.03), and treatment with anti-seizure medication (ASM) (RR (95% CI)= 2.77 (1.91, 4.03), I2= 0.00%, p < 0.01). Conversely, old age (SMD (95% CI)= -0.27 (-0.37, -0.16), I2= 66.80%, p < 0.01), a high Glasgow Coma Scale (GCS) score at presentation (SMD (95% CI)= -1.62 (-2.91, -0.34), I2= 99.70%, p = 0.01), and hypertension (RR (95% CI)= 0.84 (0.76, 0.94), I2= 25.90%, p < 0.01) were associated with a significantly lower probability of seizure occurrence in sICH patients. CONCLUSIONS: The incidence of seizures after ICH is 9.5%. Alcohol consumption, cortical involvement, lobar location, hematoma volume, hematoma evacuation, treatment with ASM, age, GCS score at presentation, and hypertension are closely tied to the occurrence of seizures after sICH.

Investigating the burden of disease dimensions (time-dependent, developmental, physical, social and emotional) among family caregivers with COVID-19 patients in Iran.

BACKGROUND: The caregivers of patients with covid-19 face constant responsibilities such as providing personal, health, and social care to family, which can be physically, and emotionally exhausting resulting in a considerable stress burden. Therefore, given the importance of the subject, this study aimed to investigate the burden of disease dimensions (time-dependent, developmental, physical, social and emotional) among family caregivers with covid-19 patients in Iran. METHODS: This cross-sectional study was conducted one year after the onset of the Covid-19 outbreak in Iran. Family caregivers of Covid-19 patients discharged from the hospitals in Kerman city, Iran, were chosen by simple randomization (n = 1500). Data were collected utilizing a demographic characteristics inventory created by the researcher as well as the Novak and Guest Caregiver Burden Inventory. Descriptive statistics such as mean and standard deviations, frequency, and percentages and analytical statistics such as Kolmogorov-Smirnov, T-test, ANOVA, and Multivariate Linear Regression were used for data analysis using the 20, SPSS Inc., Chicago, IL Software at the level of P < 0.05. RESULTS: The results demonstrated that the mean score of family caregiver burden was 2.61±0.6 and the severity of this burden was in a moderate range. The finding showed a statistical difference was seen between the family caregiver burden mean score of participants in terms of gender, duration of treatment, age and employed status. The multivariable linear regression model showed demographic variables of caregivers included (female, married, employed, elderly, low income and poor education) had a beneficial influence on family caregiver burden. CONCLUSION: The findings of this study can increase the awareness of health managers, about the level of burden of disease among family caregivers from the covid-19 patients and can help to provide economic, social and psychological support programs for improvement and reducing the burden of disease of caregivers during the covid-19 outbreaks.

Patients with degenerative cervical myelopathy exhibit neurophysiological improvement upon extension and flexion: a retrospective cohort study with a minimum 1-year follow-up.

BACKGROUND: Cervical extension and flexion are presumably harmful to patients with degenerative cervical myelopathy (DCM) because they worsen medullary compression visible on dynamic magnetic resonance imaging (MRI). Dynamic somatosensory evoked potentials (SSEPs) are an objective tool to measure the electrophysiological function of the spinal cord at different neck positions. In contrast to previous hypotheses, a considerable proportion of patients with DCM present improved SSEPs upon extension and flexion compared to a neutral position. METHODS: Patients with DCM who underwent preoperative dynamic SSEP examinations and subsequent decompression surgeries between 2015 and 2019 were retrospectively evaluated. We compared extension and flexion SSEPs with neutral SSEPs in each patient and classified them into extension-improved (EI) or extension-nonimproved (EN) and flexion-improved (FI) or flexion-nonimproved (FN) groups. Preoperative clinical evaluations, decompression surgical methods and one-year follow-up clinical data were recorded. Cervical spondylolisthesis and cervical alignment types were evaluated on plain cervical lateral radiographs. The number of stenotic segments, Mühle stenosis grade and disc degeneration stage of the most severe segment, and presence of ligamentum flavum hypertrophy and intramedullary T2 weighted imaging (T2WI) hyperintensity were evaluated on lateral and axial MRI. Data were compared between the EN and EN groups or FI and FN groups with T-tests, chi-square tests or Kruskal-Wallis tests. Prediction criteria were determined with logistic regression analyses. RESULTS: Forty-nine patients were included, and 9 (18.4%) and 11 (22.4%) showed improved extension and flexion SSEPs compared to their own neutral SSEPs, respectively. Interestingly, EI or FI patients had significantly better one-year postoperative mJOA recoveries than EN or FN patients (T-test, P < 0.001). Moreover, the disease duration (T-test, P = 0.024), involved segment number (Kruskal-Wallis test, P < 0.001), and cervical alignment type (chi-square test, P = 0.005) varied significantly between the EI and EN groups. The FI group presented a significantly higher Mühle stenosis grade than the FN group (Kruskal-Wallis test, P = 0.038). Furthermore, ≤ 2 involved segments and straight or sigmoid cervical alignment were significant criteria predicting improved extension SSEPs (probability: 85.7%), while Mühle stenosis Grade 3 and disease duration ≤6 months were significant criteria predicting improved flexion SSEPs (probability: 85.7%). CONCLUSIONS: Our findings provide evidence for neurophysiological improvement in patients with DCM at extension and flexion and its significance in predicting prognoses. Moreover, certain clinical and radiographic criteria may help predict neurophysiological improvement upon extension or flexion. TRIAL REGISTRATION: " [2020]151 ".

Identifying relevant factors for successful implementation into routine practice: expert interviews to inform a heart failure self-care intervention (ACHIEVE study).

BACKGROUND: Adherence to heart failure (HF) self-care behaviours has been found to be effective for alleviating illness symptoms, increasing quality of life and reducing hospital re-admissions and mortality. However, many patients fail to implement on-going self-care into their daily lives. It is therefore crucial to improve the behaviour of HF patients to increase self-care adherence. The aim of this study is to identify relevant factors to successfully implement a complex, theory-based HF self-care intervention into routine practice. METHODS: We conducted semi-structured interviews to obtain key stakeholders' opinions on previously developed behaviour change techniques for enhancing HF patients' self-care behaviours, in order to optimise implementation of these techniques in an intervention. The interview topic guide was developed based on the Normalisation Process Theory (NPT), a tool that takes into account the feasibility of implementation and the acceptability to stakeholders. Interviews were analysed using thematic analysis and supported by MAXQDA 2020, a software for qualitative research. RESULTS: Interview participants included 18 key stakeholders consisting of three crucial groups: clinical experts (n = 7), patients (n = 3) and high calibre policy makers/potential funders (n = 8). The interviews revealed numerous factors to consider for successful implementation of an intervention into routine practice. The findings are presented according to two major categories: (1) themes within the NPT framework and (2) themes beyond the NPT framework. Themes within the NPT component 'Coherence' include three sub-themes: 'understandability', 'value beyond existing interventions' and 'perceived benefits'. The NPT component 'Cognitive participation' revealed two sub-themes: 'time resources' and 'financial sustainability'. Finally, the NPT component 'Collective action' uncovered three sub-themes: 'need for training', 'compatibility with existing practice' and 'influence on roles'. A further two themes were identified beyond the NPT framework, namely: 'structural challenges' and (2) 'role of carers'. CONCLUSIONS: Factors identified previously by NPT were validated, but stakeholders further identified relevant aspects beyond NPT. Based on these findings, we suggest the existing NPT framework could be expanded to include a fifth component: questions considering specific environmental factors (contextual considerations). Sensitising researchers to these issues at an early stage when designing an intervention can facilitate its later success.

Factors associated with bone metastasis in breast cancer: a systematic review and meta-analysis.

BACKGROUND: To systematically evaluate and analyze the risk factors for breast cancer (BC) with bone metastasis (BM) and provide clinical evidence supporting the early prevention of BM. METHODS: We systematically retrieved databases from the Cochrane Library, PubMed, Web of Science, and EMBASE for BC with BM patient. Limited: publish cation between January 1, 2001, and December 31, 2019. Literature screening and evaluation were performed independently by 2 evaluators. The quality of all included studies was evaluated with the NOS. Studies with NOS ≥6 on factors related to the BM of BC were identified. Weighted odds ratio (OR) were used as the combined effects. RESULTS: We identified 18 articles with available data. The NOS scores ranged from 6-9. Progesterone receptor (PR)-positive BC patients had a relatively lower risk of BM [I2=45.9%, OR =0.80, 95% confidence interval (CI): 0.72, 0.88, P<0.001]. HER2-positive BC patients had a relatively higher risk of BM (I2=77.6%, OR =1.35, 95% CI: 1.04, 1.76, P=0.025). The risk of BM in patients with lymph node metastasis was higher than that in patients with no lymph node metastasis (I2=99.7%, OR =2.60, 95% CI: 1.41, 4.80, P=0.002). The risk of BM in stage T2 BC patients was 1.99 times that in stage T1 BC patients (I2=96.8%, OR =1.99, 95% CI: 1.03, 3.83, P=0.040). The risk of BM in stage T3 BC patients was 4.74 times that in stage T1 BC patients (I2=95.6%, OR =4.74, 95% CI: 1.94, 11.57, P=0.001). The risk of BM in stage T4 BC patients was 14.57 times that in stage T1 BC patients (I2=95.4%, OR =14.57, 95% CI: 4.16, 51.05, P<0.001). The incidence of BM in BC patients without lobular or ductal BC was significantly higher than that in patients with ductal BC (I2=56.4%, OR =1.26, 95% CI: 1.09, 1.45, P=0.001). DISCUSSION: Patients with PR-positive BC have a relatively lower risk of BM. Patients with HER2-positive, lymph node metastasis-positive, nonlobular, or ductal BC have a relatively higher risk of BM. With increasing T stage, the risk of BM in BC patients also increases.

@#AIM: To investigate the current situation of myopia among pupils in Baotou and analyze the factors related to myopia, so as to provide data support and theoretical basis for myopia prevention and control in education and health departments.<p>METHODS: A random cluster sampling method was adopted to investigate the vision situation of students aged 7-14 in 26 primary schools in the urban and pastoral areas of Baotou from January to November 2019, 2000 questionnaires on myopia-related factors were distributed, and 1630 valid questionnaires were finally formed, and a myopia database was established for statistical analysis. <p>RESULTS: There were 14 845 myopia among the 31 080 students surveyed, and the myopia rate was 47.8%(14845/31080). Among them, the myopia rate of boys was 44.3%(6912/15609), and that of girls was 51.3%(7933/15471). The myopia rate in urban areas was 50.4%(9310/18489)and in pastoral were as was 44.0%(5535/12591). The myopia rate of Han nationality was 48.0%(13185/27442), and of Mongolian nationality was 44.6%(1149/2576), the other ethnic groups was 48.1%(511/1062)(<i>P</i><0.05). The prevalence of myopia of 11, 12, 13,and 14-year-old urban pupils were: 51.9%(1333/2568), 62.8%(1671/2662), 72.0%(3415/4740), 45.4%(704/1551),and the pastoral areas of the same age group were 46.5%(938/2019), 58.0%(1089/1877), 68.3%(1557/2279), 36.2%(338/934). The myopia rate of urban pupils in 11-14 age group was higher than that in pastoral areas(<i>P</i><0.05). Among them, doing eye exercises and eating fruits and vegetables were protective factors. Area, grade, tummy reading, reading and writing under low light, or using electronic products, parents' myopia, and father's education were risk factors for myopia. <p>CONCLUSION: The prevalence of myopia in Baotou primary school students is at a relatively high level. With the increase of age, the prevalence of myopia increases. Many factors are related to myopia in primary school students. Parents and education departments should carry out relevant interventions.

Pain characteristics and outcomes in patients with Parkinson′s disease / 中华神经科杂志

Objective:To investigate the clinical characteristics and influencing factors of pain symptoms in patients with idiopathic Parkinson′s disease.Methods:The King′s Parkinson′s Disease Pain Scale (KPPS) was used to evaluate pain of 106 patients with Parkinson′s disease. The Pittsburgh Sleep Quality Index (PSQI), the Fatigue Scale-14 (FS-14), the Unified Parkinson′s Disease Rating Scale Ⅲ, Hoehn-Yahr scale (H-Y), Mini-Mental State Examination (MMSE), Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) were used to assess the sleep status of patients, the degree of fatigue, motor function, severity of symptoms, cognitive function, anxiety and depression. Fifty-eight patients were followed up for three to six months.Results:The incidence of pain in Parkinson′s disease patients was 50.0% (53/106), of which skeletal muscle pain was the most common. Parkinson′s disease patients with a longer course of disease were more likely to have pain [course of disease in Parkinson′s disease with pain was 3.0 (1.5, 5.0) years, in Parkinson′s disease without pain was 2.0 (1.5, 2.5) years, Z=-2.0, P=0.046]. Male patients had more severe pain than female patients [KPPS scores in males were 14.5 (8.0, 21.5), in females were 10.0(4.0, 15.3), Z=-2.81, P=0.005]. In the first evaluation, the H-Y grading and the FS-14 scores of Parkinson′s disease patients with pain were significantly higher than those without pain [H-Y grading in Parkinson′s disease patients with pain was 2.0 (1.5, 2.5), in Parkinson′s disease patients without pain was 2.0 (1.5, 2.0), Z=-2.02, P=0.043; FS-14 scores in patients with pain were 10.0 (8.0, 11.0), in patients without pain was 8.0 (5.0, 10.0), Z=-3.32, P=0.001]. The KPPS scores were positively correlated with the scores of HAMA and HAMD ( r=0.39, P=0.005; r=0.38, P=0.007). Binary Logistic regression analysis showed that Parkinson′s disease patients with higher scores of FS-14 had an increased risk of developing pain ( OR=1.27, 95% CI: 1.09-1.48, P=0.002). The changes of KPPS scores were associated with the changes of PSQI and FS-14 scores ( r=0.54, P=0.002; r=0.50, P=0.003). The decrease of KPPS scores was only positively correlated with the decrease of FS-14 scores when the drug and medication status remained unchanged ( r=0.421, P=0.045). Multiple linear regression analysis showed that the decrease of FS-14 scores was associated with the decrease of the KPPS scores ( OR=2.02, P=0.033). Conclusions:Parkinson′s disease patients have a high incidence of pain, and fatigue is a factor for predicting the occurrence and outcome of pain in Parkinson′s disease. The severity and change of pain in Parkinson′s disease patients are related to anxiety, depression, sleep and fatigue, suggesting that there may be a common pathogenesis of pain, emotion, sleep and fatigue in Parkinson′s disease patients.

Fundus screening was performed. And the incidence of retinopathy of prematurity was calculated according to the diagnostic criteria, and univariate and multivariate Logistic regression analysis was performed on the related data of the mothers before and during pregnancy.<p>RESULTS: There was no retinopathy in the whole moon, but 36 cases of premature infants with retinopathy of prematurity. And the incidence of the disease was 14.8%(36/243). Among them, about half(58.3%)of the children with stage Ⅰ disease. Followed by stage Ⅱ disease(30.6%), stage Ⅲ disease(8.3%)and stage Ⅳ disease(2.8%), no stage Ⅴ disease were found. Meanwhile, 2 children with threshold lesions(5.6%). Except for the gestational age, there were no significant differences in the related factors of menstruation, gestational age, gestational births and pregnancy complications between full-term and normal preterm mothers(<i>P</i>>0.05), but compared with the mothers of premature infants, the differences were statistically significant(<i>P</i><0.05). The irregular menstruation, older pregnancy, gestational age short, polyembryony, eclampsia, PIH, diabetes and perinatal infection were independent risk factors for retinopathy of prematurity(<i>P</i><0.05).<p>CONCLUSION: The incidence of retinopathy of prematurity is high in Sanya, which should be paid great attention. At the same time, there are many influencing factors. It is an effective method to reduce retinopathy of prematurity in this area that menstrual conditioning before pregnancy, avoid advanced pregnancy, term birth, monocyesis and control pregnancy complications.

Relevant factors for early liver transplantation after Kasai portoenterostomy.

BACKGROUND: To explore the relevant factors for early liver transplantation (LT) after Kasai portoenterostomy (KP). METHODS: Retrospective analysis was performed for 200 children with biliary atresia, who underwent LT with hepatic failure after KP. According to the interval between KP and LT, they were divided into three groups: G1 (≤6-month), G2 (6-month~ 2-year) and G3 (> 2-year). Gender, age of Kasai portoenterostomy, jaundice-clearance, cholangitis after KP and liver function indexes before LT were compared among the three groups. RESULTS: The proportion of patients with age of KP (≤90-day) in G1 was lower than that in G3 (P = 0.003). Jaundice-clearance occurred in 6 (7.6%), 26(28.6%) and 26 (86.7%) patients after KP in G1, G2 and G3 respectively (P < 0.001). There were statistical differences in the incidence of early cholangitis, late cholangitis and repeated cholangitis among the three groups (P = 0.035, < 0.001 and 0.022). The native liver survival (NLS) rate of children at operation age > 90-day was lower than that of children at operation age ≤ 90-day (P = 0.002). The NLS rate of the children with jaundice-clearance after KP was significantly better than that of the children without jaundice-clearance (P < 0.001). The NLS rate of the children with early cholangitis after operation was lower than that in children without early cholangitis (P = 0.026). The NLS rate of patients of G2 and G3 with cholangitis after KP was lower than that in children without cholangitis (P = 0.017). Multiple logistic regression analysis showed uncleared jaundice after KP was a risk factor for the NLS time in patients. CONCLUSION: The age of KP (> 90-day), jaundice-unclear and early cholangitis could reduce the NLS time after KP, which were related to early liver transplantation. Jaundice-unclear was a risk factor for early liver transplantation.

Metabolic syndrome in systemic lupus erythematosus was closely related to body mass index, blood pressure, blood sugar, blood lipids, and arthritis.

BACKGROUND AND OBJECTIVE: Prevention and control of metabolic syndrome is the key to improving the development of systemic lupus erythematosus. The aim of this study was to analyze the relevant factors regarding metabolic syndrome (MS) in systemic lupus erythematosus (SLE). METHODS: A total number of 1238 SLE patients in Yijishan Hospital of Wannan Medical College, Anhui province, from February 2012 to July 2017, were analyzed retrospectively. SLE patients with MS were grouped to group SLE-MS, the others without MS was grouped to group SLE-nMS. The two groups were compared with respect to general characteristics, clinical signs, and laboratory parameters. Random forest approach and multivariate logistic regression were conducted to analyze the related factors regarding MS in SLE. RESULTS: The constituent ratio of metabolic syndrome was 27.14% (336/1238). More SLE patients with MS presented with more farmers, more married people, lower education level, and more lupus nephritis, proteinuria, oral ulcers, tubular urine, hematuria than SLE patients without MS (P<0.05). Moreover, eighteen important variables, whose average importance scores were highest and whose error rates were lowest, were selected by random forest method. Data from multivariate logistic regression showed that MS in SLE was related with BMI, diastolic blood pressure, systolic blood pressure, fasting blood glucose, arthritis, urea, triglycerides, high-density lipoprotein, and white blood cells. CONCLUSION: MS in SLE was closely related to BMI, blood pressure, blood sugar, blood lipids, arthritis, white blood cells, and urea. Targeted prevention and conclusion measures for the risk factors should be taken as early as possible.

Epidemiological features of rosacea in Changsha, China: A population-based, cross-sectional study.

Rosacea is a common chronic skin disorder of unknown etiology. While population prevalence rates range 0.2-22% in Europe and North America, prevalence in China is currently undetermined. We conducted a large population-based case-control study to determine the present epidemiological status of rosacea in China, involving 10 095 participants aged 0-100 years (mean age, 35.5 ± 19.1; 50.5% female). A census of rosacea among 15 communities in Changsha in south central China was conducted with skin examination by board-certified dermatologists. Rosacea was observed in 3.48% (95% confidence interval, 3.13-3.85%) of the study population. Subtype distribution was erythematotelangiectatic in 47.6%, papulopustular in 35.0% and phymatous in 17.4%. Family history was noted in 37.8% and ocular symptoms in 31.3%. Associations with rosacea were observed for melasma, hypertension, hyperthyroidism and breast cancer in females (P < 0.05), and also for hyperthyroidism and peptic ulcers in males (P < 0.05). Our results provide baseline information about epidemiological aspects of rosacea in China.

Distribution of Traditional Chinese Medicine Syndromes and Relevant Factors in 6 Months After Percutaneous Coronary Intervention / 中国实验方剂学杂志

Objective:To investigate the distribution of traditional Chinese medicine (TCM) syndromes in patients with coronary heart disease (CHD) in 6 months after interventional therapy, and to analyze relevant influencing factors. Method:The clinical data of 1 000 patients with coronary heart disease in 6 months after interventional therapy, including the four diagnosis information of TCM, were collected, and the distribution of TCM syndromes and the influencing factors were analyzed. Result:Among 48 kinds of information about the four diagnostic methods of TCM, chest pain was the most frequent (98.10%)， among 9 kinds of common TCM syndrome types, blood stasis was the most frequent (89.90%), and the others were heart-Qi deficiency syndrome, phlegm turbidity syndrome, cold-dampness syndrome, kidney-Qi deficiency syndrome, heart-Yin deficiency syndrome, kidney-Yin deficiency syndrome, Heart-Yang deficiency syndrome and kidney-Yang deficiency syndrome in turn. Among 6 common TCM syndrome types, Qi deficiency and blood stasis syndrome were the most frequent (35.40%), and the others were phlegm turbidity and blood stasis syndrome, cold congealing heart pulse syndrome, Qi-Yin deficiency syndrome, heart-kidney Yin deficiency syndrome and heart-kidney-Yang deficiency syndrome in turn. There was no significant difference in sex ratio among different syndrome types . Patients with heart-kidney Yang deficiency syndrome had no significant difference. Compared with the average age of other syndromes, there were significant differences. Common complications included hypertension, diabetes, cerebrovascular diseases and dyslipidemia, among which hypertension had the highest frequency, with significant differences from other diseases (P<0.05). Phlegm, turbidity and blood stasis were found in patients with hypertension. The risk of syndromes was higher (OR=3.29, 95% CI [2.11, 5.05]), while the risk of cold congealing heart pulse syndrome was lower (OR=0.56, 95% CI [0.32, 0.98]), the risk of Qi and Yin deficiency was higher (OR=2.88, 95% CI [2.01, 4.99]), whereas the risk of heart and kidney Yang deficiency was lower (OR=0.54, 95% CI [0.29, 0.95]) when complicated with cerebrovascular diseases. The risk of Qi deficiency and blood stasis was higher (OR=2.97, 95% CI [2.05, 5.28]), while the risk of heart and kidney Yang deficiency was lower (OR=0.54, 95% CI [0.29, 0.95])， the risk of phlegm turbidity and blood stasis was higher when complicated with dyslipidemia (OR=3.55, 95% CI [2.32, 5.29]), and the risk of heart and kidney Yang deficiency was lower (OR=0.54, 95% CI [0.29, 0.95]). The time distribution of the disease had obvious seasonal characteristics. Conclusion:The main distribution characteristics of TCM syndromes in 6 months after coronary heart disease intervention are basically the same as those in patients without intervention. The main TCM syndromes are Qi deficiency and blood stasis syndrome, phlegm turbidity and blood stasis syndrome, cold congealing heart pulse syndrome, Qi-Yin deficiency syndrome, heart-kidney Yin deficiency syndrome and heart-kidney-Yang deficiency syndrome. The distribution pattern may be related to age, complications and seasons.
