Relative score of early neurological deterioration in perforator artery infarction: a retrospective study.

BACKGROUND AND AIMS: Compared to small vessel occlusion (SVO) patients, branch atheromatous disease (BAD) patients are more likely to develop early neurological deterioration (END). Stroke patients with END have a poor prognosis. Initial clinical features/radiological findings are often insufficient to distinguish between BAD and SVO; therefore, they may not detect END. In this retrospective study, we investigated relative factors for END in perforator artery infarction and created a scoring system for END in these patients. METHODS: We extracted data from stroke patients with perforator artery infarction admitted to the Department of Neurology at Juntendo University between January 2016 and December 2022. We examined factors, such as the presence of SVO and BAD, leading to END. Variables with a P-value < 0.1 on univariate analysis were entered into binominal logistic regression analysis. RESULTS: Of the 1,420 stroke patients admitted over a 7-year period, 201 with perforator infarction were included in this study. END was found in 27 of 201 patients (13.4%). Binominal logistic regression analysis of background factors less than p < 0.1 revealed that age > 69 (P = 0.032; odds ratio [OR], 3.941; 95% confidence interval [CI], 1.126-13.769), body mass index < 23.8 (P = 0.041; OR, 3.183; 95%CI, 1.049-9.654), and pretreatment with anti-platelets (P = 0.003; OR, 5.183; 95%CI, 1.783-15.071) were significant factors. Regarding anti-platelet therapy, END was observed in 34.4% of patients administered aspirin and 35.0% administered clopidogrel. Initial infarct lesion size over 15 mm on initial MRI had a P value of 0.076 in univariate analysis and an odds ratio of 1.330 (95% CI 0.471-3.755; P = 0.590) in binomial logistic regression analysis. The length of stay and modified Rankin Scale at discharge were significantly exacerbated in the END group. Creating a scoring system with 1 point for each relevant factor (pEND score), significant correlations were obtained with ROC curves, and over 2 points produced the highest sensitivity and specificity for detecting END. CONCLUSION: Patients with high pEND scores may require intensive care from early hospitalization. In addition, the occurrence of stroke during anti-platelet therapy suggests the need for alternative treatment.

Analysis of the current situation of defect of vertebral column among primary， middle， and high school students in Minhang District， Shanghai / 上海预防医学

ObjectiveTo investigate the general situation of defect of vertebral column among primary and middle school students in Minhang District of Shanghai and analyze the related factors， to provide a scientific basis for prevention and treatment. MethodsFrom September to October 2022， a total of 5 715 students were selected from two primary schools， two middle schools， and two high schools in Minhang District for physical examinations and screening for defect of vertebral column. ResultsTotally 219 students had defect of vertebral column， accounting for 3.83% of the sampled population. Anteroposterior spinal abnormalities were found in 4 individuals， accounting for 0.07%， and 218 students had scoliosis， accounting for 3.81%. The detection rate of defect of vertebral column was higher in girls （6.27%） than that in boys （1.51%）， and higher in high school students （10.74%） than in primary school students （1.31%） and middle school students （10.97%）. Students who are mildly underweight （5.95%） and who are moderately to severely underweight （7.46%） had a higher detection rate of defect of vertebral column than those with normal weight （4.54%）， overweight （2.83%）， and obesity （1.60%）. The detection rate among students with poor vision （4.32%） was significantly higher than those with normal vision （2.24%）， with all differences statistically significant （all P<0.05）. ConclusionThe positive rate of defect of vertebral column in primary and middle school students in Minhang District， Shanghai is nearly 4%， with most cases being scoliosis. Factors such as being female， increasing age， being underweight， and poor vision are associated with a higher probability of detecting defect of vertebral column.

Timely referral to health centers for the prevention of cardiovascular diseases: IraPEN national program.

Introduction: The IraPEN program is an adapted version of the WHO-PEN program designed to prevent four major non-communicable diseases in Iran. This study aimed to determine the rate of compliance and related factors among individuals participating in the IraPEN program for the prevention of cardiovascular disease. Method: In this study, compliance was defined as timely referral to the health center as scheduled, and the researchers approached four pilot sites of IraPEN from March 2016 to March 2018. Sex-stratified logistic regressions were applied to investigate factors related to compliance. However, it is important to note that in this study, compliance was defined as compliance to revisit, not compliance to taking prescribed medications or behavioral lifestyle changes. Results: The total compliance rate, including timely compliance and early and late compliance, was 16.5% in men and 23.3% in women. The study found that cardiovascular risk factors such as diabetes, hypertension, hypercholesterolemia, and being underweight were associated with lower compliance. The higher calculated risk of CVD was associated with higher compliance, but after adjusting for cardiovascular risk factors, high-risk individuals showed lower compliance. There was negligible interaction between sex and other factors for compliance. Conclusion: The compliance rate with scheduled programs for cardiovascular preventive strategies was very low, and high-risk individuals were less compliant, regardless of their high level of risk factors. The study recommends further training to increase awareness and knowledge regarding the IraPEN program and the prevention of non-communicable diseases among high-risk populations.

Office-based 532-nm KTP laser as a therapeutic modality for recurrent laryngeal papillomatosis: efficacy and relative factors.

This study aims to investigate the efficacy of office-based potassium-titanyl-phosphate (KTP) 532-nm laser in the management of recurrent laryngeal papillomatosis (RLP) following other treatments. A retrospective assessment was performed on 55 patients in 259 cases of RLP between 2012 and 2019. Derkay scores were obtained for all patients who underwent 532-nm KTP laser procedure (6 W of power with a continuous output mode) prior to treatment and after treatment. Analysis of parameters is based on the distribution characteristics of data. An ordinal logistic regression was also performed. Patients received a median of 3 (range 1-24) office-based KTP laser treatments. Among them, 96.36% (53 patients) were previously on cold steel equipment, CO2 laser, or microdebrider treatment under general anesthesia, and all previous treatments on them had failed. One patient progressed to invasive cancer, so he was excluded from the following analyses. After final KTP treatment, 36 patients (66.67%) received complete resolution with follow-up time ranging from 12.9 to 80.53 months (median 55.54 months). Results of subjective voice-quality indicators such as VHI-30 and GRBAS all improved greatly at the last follow-up. The initial Derkay scores and treatment intervals were found to be predictive of complete lesion remission. Arytenoid involvement may also correlate with lesion resolution. Serial office-based KTP treatment is an effective option for RLP patients, with ideal disease control and voice quality preservation. KTP laser therapy should be repeated with an interval of 1 month from the beginning of treatment until the lesion has been evaluated and subsided. Non-bulk or scattered laryngeal papilloma is an appropriate indication for KTP laser treatment.

Absence of high-grade cervical intraepithelial neoplasia in conization specimens from patients with colposcopic biopsy-confirmed high-grade cervical intraepithelial neoplasia: Retrospective study of 1695 cases.

Few studies have investigated the absence of high-grade cervical intraepithelial neoplasia (CIN) in excised specimens, and sample sizes of these studies were limited. This study retrospectively analyzed clinical characteristics of 1695 patients with CIN 2/3 to determine the incidence rate and relative factors of CIN 1 or less in conization specimens from patients with colposcopic biopsy-confirmed CIN 2/3. The study group comprised 430 cases of CIN 1 or less in conization specimens, and the control group comprised 1142 cases with high-grade CIN lesions in conization specimens. Univariate and multivariate logistic regression models were established to evaluate relative factors. The 1-9 years follow-up data were analyzed to determine the persistence/recurrence rate. Multivariate logistic regression showed that patients aged 18-24 years (OR (95% CI) = 2.224 (1.014, 4.877)); with a negative hrHPV test result (OR (95% CI) = 3.210 (1.627, 6.331)); a cytology test result of normal (OR (95% CI) = 5.184 (3.138, 8.563)), ASC-US (OR (95% CI) = 3.420 (2.102, 5.564)), LSIL (OR (95% CI) = 2.588 (1.475, 4.541)), or ASC-H (OR (95% CI) = 2.434 (1.306, 4.539)); an indication of CIN 2 on biopsy (OR (95% CI) = 2.290 (1.694, 3.096)), and no glandular involvement (OR (95% CI) = 1.616 (1.205, 2.169)) were more likely to have an absence of high-grade dysplasia in conization specimens. There was no difference in the persistence/recurrence rate between the two groups (x2 = 1.55, P = 0.46). An age of 18-24 years, a negative hrHPV test result, a non-HSIL cytology test result, an indication of CIN 2 on biopsy, and no glandular involvement were relative factors for an absence of high-grade dysplasia in conization specimens. For patients with relative factors, especially young women, informed follow-up should be considered.

[Risk factors of hidden blood loss in percutaneous vertebral augmentation].

OBJECTIVE: To explore the risk factors of hidden blood loss in osteoporosis vertebral compression fractures during percutaneous vertebral augmentation. METHODS: From October 2018 to December 2019, 360 patients with osteoporosis vertebral compression fractures who received percutaneous vertebral augmentation were enrolled in this study. The factors analyzed included gender, age, surgical methods, disease course, height, weight, the operative segment, bone mineral density, amount of bone cement, operative time, percentage of height loss, percentage of vertebral height restoration, cement leakage, blood clotting function, preoperative and postoperative hemoglobin and hematocrit and other internal diseases. Total blood loss was calculated by Gross's formula, influential factors of the hidden blood loss were further analyzed by t-test, multivariate linear regression and one-way ANOVA analysis. RESULTS: Surgical methods, the operative segment, disease course, cement leakage, preoperative hemoglobin, cement leakage via the basivertebral and segmental vein were significantly correlated with hidden blood loss(P<0.05). CONCLUSION: Patients with percutaneous kyphoplasty, two-level and multi-level surgery, the course of the disease beyond 6 weeks, cement leakage via the basivertebral and segmental vein, and lower preoperative hemoglobin had more perioperative hidden blood loss.

Analysis of related factors of scheduled ICU before primary hip arthroplasty.

BACKGROUND: Methods for improving the safety of medical treatments for patients, reducing the occurrence of postoperative complications and optimizing medical resources for primary hip replacement are needed. Previous literature has mostly analysed the risk factors and constructed and models to predict a transfer to the ICU after surgery, and no reports on preoperative ICU reservations have been found. This study evaluated the risk factors for preoperative ICU reservation and considered the necessity of preoperative ICU reservations to optimize preoperative communication, enable a seamless transfer between the operating room and ICU, reduce postoperative complications and shorten hospital stays. METHODS: We extracted the data of 1488 patients who underwent hip replacement from the hospital case database from November 2017 to May 2021 and used the case-control test to divide the patients into the case group (scheduled ICU admission, 134 cases) and the control group (Not scheduled ICU admission, 213 cases). The general conditions of the patients before surgery, including sex, age, Charlson comorbidity index, laboratory test results, and anaesthesia methods, were collected and used as independent variables. The t test, rank sum test, and X2 test were used to analyse and identify significant factors with a P < 0.05. Then, these factors were entered into binary logistic regression analysis, and a ROC curve was used to test the efficacy of the regression model. RESULTS: In the data we collected, 134 patients were planned to be transferred to the ICU, and 213 patients were not transferred to the ICU. The two groups of data were analyzed by logistic regression. We defined the risk factors for preoperative ICU appointment in patients with primary hip arthroplasty, including age. (odds ratio (OR) 1.066, 95% (confidence interval) CI (1.039, 1.093), P < 0.001), general anesthesia ( (OR) 1.821, 95%CI (1.165, 2.845), P = 0.008), preoperative C-reactive protein ((OR) 1.016, 95%CI (1.010, 1.022), P < 0.05), preoperative alanine aminotransferase ((OR) 1.042, 95%CI ((1.016, 1.070)), P = 0.002). These were promoting factors for preoperative ICU appointment,and preoperative albumin ((OR) 0.0839, 95%CI (0.792, 0.889)), P < 0.05) was a protective factor for ICU appointment. CONCLUSION: For patients requiring primary hip replacement. Age, general anesthesia, preoperative C-reactive protein, preoperative alanine aminotransferase and preoperative albumin are the key points of our preoperative assessment. Paying attention to the changes of these indicators will help surgeons assess the patient's condition and contact the ICU in advance.These data can be fully understood by the patients' families, reduce the unnecessary use of medical resources, and optimize perioperative management.

Factors Related to Curative Effect of Brain-computer Interface Training on Upper Limb Paralysis after Stroke / 中国康复理论与实践

Objective:To explore the factors affecting curative effect of motor imagery brain-computer interface (MI-BCI) training on upper limb paralysis for subacute stroke patients. Methods:From January, 2018 to July, 2019, 23 inpatients with post-stroke upper limb paralysis accepting MI-BCI training were reviewed. The gender, age, course of disease, aphasia, location and nature of lesion, history of Botulinum toxin, hemisphere injured and modified Ashworth Scale (MAS) score of affected fingers were recorded, and they were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) before and four weeks after MI-BCI training. According to improvement of FMA-UE wrist and hand scores (≥ 2), the patients were divided into effective group (n = 11) and inefficacy group (n = 12). Results:The MAS scores before MI-BCI training (t = 2.677, P < 0.05) and history of botulinum toxin (Z = 0.000, P < 0.05) were more in the inefficacy group than in the efficacy group. FMA-UE scores (total and dimensions) after training were correlated to their baseline levels (r > 0.831, P < 0.01), FMA-UE total scores (Eta = 0.453, P < 0.05) and upper arms scores (Eta = 0.506, P < 0.05) were correlated to aphasia, FMA-UE scores of hands were correlated with MAS (r = -0.521, P < 0.05). Conclusion:Poor baseline motor function, spasticity and complication with aphasia were the factors unfavorable to MI-BCI training for subacute stroke patients with upper limb paralysis.

[Practice of parenting and related factors on children aged 0-5 in the urban areas of China].

Objective: To characterize the relations between the practice of parenting and associated factors on children (0-5 years old) in urban areas of China, in order to provide evidence for promoting the early development of children and to provide positive guidance and service programs on parenting. Methods: A total of 4 515 parents from 15 cities (14 provinces) were surveyed with a self-administered questionnaire. Parenting and Family Adjustment Scales (PAFAS) was used, including parameters as: consistency and coercive parenting, positive encouragement, parent-child relationship and parental emotion adjustment, family relationship and parental teamwork aspects, etc. Both single factor analysis and multiple linear regression were used to examine the associations between parenting practice, individual, parental and family factors. Results: The mean score of PAFAS was 21.00 (15.00-28.00), associated with factors as children's age, only-child family, premature delivery, father's education level, confidence on parenting, problems regarding the parental mood, annual family income, family structure and behavior on seeking professional help, etc. Results showed that there were big differences on the practice of parenting in China and influenced by variety of factors. Conclusions: The general situation of parenting was well, in the urban areas of China. The practice of parenting was associated with a series of individual, parental and family factors. Programs on improving the parenting skills and promoting the early development of children, should be highlighted.

Characteristics and relative factors of headache caused by cervicocerebral artery dissection.

OBJECTIVE: To analyze the characteristics and relative factors of headache and neck pain due to cervicocerebral artery dissection (CAD). METHODS: A total of 146 consecutive patients with CAD in Zhengzhou, China (2010-2017) were observed and registered prospectively. There were 60 (60/146) cases who complained of headache and neck pain, and we analyzed the characteristics of pain according to their clinical features. For the 130 (130/146) patients with complete clinical laboratory data, they were divided into two groups according to pain, and the relative factors of pain were analyzed. RESULTS: The headache and neck pain in 60 CAD patients was mostly acute onset (98.3%), 70.6% (12/17) of patients with anterior circulation dissection and 88.4% (38/43) of patients with posterior circulation dissection complained of moderate to severe pain. 41.2% (7/17) of patients with anterior circulation dissection had temporal pain, while 46.5% (20/43) of the patients with posterior circulation dissection had occipital pain. There were 23.5% (4/17) and 32.6% (14/43) of patients with anterior and posterior circulation dissection complained of throbbing pain, respectively, 23.5% (4/17) and 20.9% (9/43) of patients with anterior and posterior circulation dissection complained of pulsating pain. The pain could occur in the ipsilateral (40.0%), bilateral (52.7%), or contralateral (7.3%) sites of the dissection. In the 130 patients, there were 56 cases (43.1%) in the pain group, and 74 cases (56.9%) in the non-pain group. Multivariate logistic regression analysis showed that female gender (OR 4.01, 95% CI 1.63-9.85, P = 0.002), posterior circulation (OR 3.18, 95% CI 1.39-7.28, P = 0.006), history of headache (OR 4.72, 95% CI 1.08-20.52, P = 0.039), and low-density lipoprotein less than 1.8 mmol/L (OR 2.90, 95% CI 1.15-7.34, P = 0.025) were risk factors of the occurrence of the pain related to CAD. CONCLUSION: The headache and neck pain caused by CAD is a moderate to severe pain occurring suddenly. The pain nature may be diverse but mostly like throbbing and pulsating. When the dissected artery is located in the posterior circulation, the pain is mostly in the occipital region, and mostly in the temporal region when the dissected artery is located in the anterior circulation. The pain can occur in ipsilateral, bilateral, or contralateral of the dissection. In addition, several factors might contribute to the occurrence of headache and neck pain.

Relative Factors of Functional Recovery after Upper Limb Replantation / 中国康复理论与实践

Objective To analyze the relative factors of functional recovery after upper limbs replantation. Methods From September, 2009 to March, 2014, 24 consecutive patients after upper limb replantation for amputation were retrospectively analyzed. The Disability of Arm Shoulder and Hand (DASH) was used to assess the functional recovery of the upper limbs at the last follow-up. The non-conditional Logistic regression was used to analyze the correlation of gender, age, time from injury to surgery, amputated level, amputated method, isch-emia hours, dominant hand or not, rehabilitation treatment, rehabilitation duration, and the DASH scores. Results The DASH score was>28.50 in 15 patients, while ≤28.50 in 9 patients. The Logistic regression analysis demonstrated that amputated method and rehabilitation treatment correlated with the functional recovery of upper limbs (χ2>7.360, P0.05). Conclusion The amputated method and rehabilitation treatment after operation are the factors related to the func-tional recovery after upper limb replantation.

Clinical evaluation of fatigue in Japanese patients with Parkinson's disease.

BACKGROUND: Fatigue is a common nonmotor symptom of Parkinson's disease (PD). Although the causes of fatigue were estimated in the previous reports, fatigue is not fully understood. To determine the frequency of and factors related to fatigue in patients with PD, we carried out clinical assessments in our university hospital. METHODS: We used the Japanese version of the Parkinson Fatigue Scale (J-PFS). The J-PFS was administered to 110 patients with PD, and a cutoff point of 3.3 was used for the diagnosis of fatigue. Subsequently, demographic characteristics, clinical features, and medications utilized were evaluated to elucidate the factors related to fatigue. In particular, we focused on the relationship between fatigue and gait disorder assessed via the portable gait rhythmogram. RESULTS: The frequency of fatigue in patients with PD was 52.7%. Univariate analysis revealed that factors significantly associated with fatigue were many motor symptoms and nonmotor symptoms. In addition, multivariate analysis revealed that gait disorder and constipation were independent factors related to fatigue. Furthermore, short-step walking and bradykinesia in gait disorder had especially a relationship with fatigue. CONCLUSIONS: More than half of our patients were judged having fatigue. Several factors, including motor and nonmotor symptoms, might be related to fatigue in patients with PD.

Prevalence and Relative Factors of Cognitive Disfunction in Old Adults in Conmmunity of Luzhou, Sichuan, China / 中国康复理论与实践

Objective To investigate the prevalence and relative factors of cognitive disfunction among the community-dwelling old adults. Methods 766 participants over 60 years old dwelling in Luzhou, Sichuan, China were enrolled with Multi-stage stratified sampling. Information about sociodemographic characteristics, lifestyle, health condition, nutrition were interviewed, and their cognitive function was evaluated with Mini-Mental State Examination (MMSE). Results The prevalence of cognitive disfunction was 19.7%among them. Gender (male vs. female, OR=0.577), age (over 90 years vs. 60-64 years, OR=29.857), administrator (administrator vs. not administrator, OR=0.360), farmer (farmer vs. not farmer, OR=2.121), nutrition (malnutrition vs. eutrophia, OR=2.460), body weight (underweight vs. normal weight, OR=3.222), living status (UN-Habitat vs. living alone, OR=0.658), marital status (widowed vs. not widowed, OR=2.208), education attainment (junior college vs. illiteracy, OR=0.328), income (over 1000 yuan vs. no income, OR=0.596) significantly related with cognitive disfunction (P<0.05). Multiple Logistic regression analysis showed that old age, occupation (farmer) and malnutrition were independent risk factors for cognitive disfunction. Conclusion The cognitive disfunction related with multi-factors, and need more effective and available in-tervention in the old adults.

Study on relative factors between childhood abuse and the suicidal ideation among recruits / 中华行为医学与脑科学杂志

Objective To explore the effect of childhood abuse on suicidal ideation and the influencing factors among recruits.Methods Through stratified sampling,505 recruits in Nanjing were tested by childhood Trauma Questionnaire (CTQ),Simplified Coping Style Questionnaire (SCSQ),Social Support Rating Scale (SSRS),Self-rating Idea of Suicide Scale(SIOSS) and Beck Hopelessness Scale (BHS).Results 1.The scores of suicidal ideation and hopelessness in recruits who had childhood abuse were significantly higher than those in control group ((5.56±4.58) vs (2.11±2.79),(5.93±3.01)vs (3.10±2.27),P＜0.01).2.The score of positive coping in recruits who had childhood abuse was significantly lower than that in control group(18.98±6.16 vs 23.27±7.45; P＜0.05).The score of negative coping in recruits who had childhood abuse was significantly higher than that in control group(9.27±5.04 vs 23.27±7.45; P＜0.01).3.The scores of social support in recruits who had childhood abuse were significantly lower than that in control group ((69.38± 10.43),(20.16±3.97),(25.73±3.68),(22.82±5.52) vs(75.55±9.67),(23.25±2.50),(27.56±3.51),(24.67±5.33) ; P＜0.05).4.The score of total CTQ was positively correlated with suicidal ideation,hopelessness,negative coping(r=0.379,0.402,0.228; P＜0.01),but negatively correlated with active coping style,social support(r=-0.285,-0.302; P＜0.01).Conclusion The recruits who had childhood abuse are susceptible to suicidal ideation.The negative coping style and lacking of social support may be the main factors to the suicidal ideation.

The relationship between aggressive behaviors and clinical features in the inpatients with schizophrenia / 中华行为医学与脑科学杂志

Objective To explore the relative factors of aggressive behaviors in inpatients with schizophrenic.Methods 178 cases of continuously admitted schizophrenic patients were divided into attack group and non aggressive group according to the aggressive behavior of preadmission.Single factor analysis and multi factor regression analysis was applied to two groups in situation(such as age,gender,education level,course of disease,past aggressive behaviors and so on),Brief Psychiatric Rating Scale (BPRS) and Eysenck Personality Questionnaire (EPQ).Results By single factor analysis,attack group had significantly longer course of disease(7.73±6.67) than non aggressive group (5.22 ± 5.47,t =2.631,P＜ 0.01).The score of hostile suspicious factor in BPRS (13.73 ± 3.098) in attack group was significantly higher than that in nonaggressive group(11.47±3.93) (t=4.063,P＜ 0.01),but anxiety factor (7.18± 3.583) was significantly lower than that in nonaggressive group (8.70 ± 3.89) (t=2.679,P＜0.01).The score of E scale of EPQ(11.99±4.340) in attack group was significantly higher than that in nonaggressive group(10.67±4.293) (t=1.990,P＜0.01).Attack group's proportion of patients of previous attacks (71.1％) was significantly higher than that in non aggressive group (16.0％),(x2 =39.082,P＜ 0.01).(2) Logistic analysis showed that hostile suspicious factor in BPRS and past aggressive behaviors entered the regression equation.Condusions Aggressive behavior in schizophrenic patients occurs mainly with psychiatric symptoms and the past history of aggressive behavior.The patients should be treated actively to control the symptoms and prevent the disease recurrence.
