Multiparameter MRI-based radiomics nomogram for preoperative prediction of brain invasion in atypical meningioma:a multicentre study.

OBJECTIVE: To develop a nomogram based on tumor and peritumoral edema (PE) radiomics features extracted from preoperative multiparameter MRI for predicting brain invasion (BI) in atypical meningioma (AM). METHODS: In this retrospective study, according to the 2021 WHO classification criteria, a total of 469 patients with pathologically confirmed AM from three medical centres were enrolled and divided into training (n = 273), internal validation (n = 117) and external validation (n = 79) cohorts. BI was diagnosed based on the histopathological examination. Preoperative contrast-enhanced T1-weighted MR images (T1C) and T2-weighted MR images (T2) for extracting meningioma features and T2-fluid attenuated inversion recovery (FLAIR) sequences for extracting meningioma and PE features were obtained. The multiple logistic regression was applied to develop separate multiparameter radiomics models for comparison. A nomogram was developed by combining radiomics features and clinical risk factors, and the clinical usefulness of the nomogram was verified using decision curve analysis. RESULTS: Among the clinical factors, PE volume and PE/tumor volume ratio are the risk of BI in AM. The combined nomogram based on multiparameter MRI radiomics features of meningioma and PE and clinical indicators achieved the best performance in predicting BI in AM, with area under the curve values of 0.862 (95% CI, 0.819-0.905) in the training cohort, 0.834 (95% CI, 0.780-0.908) in the internal validation cohort and 0.867 (95% CI, 0.785-0.950) in the external validation cohort, respectively. CONCLUSIONS: The nomogram based on tumor and PE radiomics features extracted from preoperative multiparameter MRI and clinical factors can predict the risk of BI in patients with AM.

Acupuncture Versus Oral Medications for Acute/Subacute Non-Specific Low Back Pain: A Systematic Review and Meta-Analysis.

PURPOSE OF REVIEW: Pharmacologic intervention do not always achieve benefits in the treatment of acute/subacute non-specific low back pain (NSLBP). We assessed efficacy and safety of acupuncture for acute/subacute NSLBP as alternative treatment. RECENT FINDINGS: We searched PubMed, Web of Science, Embase, Cochrane Library, Scopus, Epistemonikos, CNKI, Wan Fang Database, VIP database, CBMLD, CSTJ, clinical trials, EUCTR, World WHO ICTRP, and ChiCTR for randomized controlled trials, cross-over studies, and cohort studies of NSLBP treated by acupuncture versus oral medication from inception to 23th April 2022. A total of 6 784 records were identified, and 14 studies were included 1 263 participants in this review. The results of the meta-analysis indicated that acupuncture therapy was slightly more effective than oral medication in improving pain (P < 0.00001, I2 = 92%, MD = -1.17, 95% CI [-1.61, -0.72]). According to the results of the meta-analysis, acupuncture therapy exhibited a significant advantage over oral medication with a substantial effect (P < 0.00001, I2 = 90%, SMD = -1.42, 95% CI [-2.22, -0.62]). Based on the results of the meta-analysis, acupuncture therapy was associated with a 12% improvement rate compared to oral medication in patients with acute/subacute NSLBP (P < 0.0001, I2 = 54%, RR = 1.11, 95% CI [1.05, 1.18]). Acupuncture is more effective and safer than oral medication in treating acute/subacute NSLBP. This systematic review is poised to offer valuable guidance to clinicians treating acute/subacute NSLBP and potentially benefit the afflicted patients.

Plum-blossom needle therapy for Tourette syndrome: A case report.

INTRODUCTION: Tourette syndrome (TS) is a neurodevelopmental disorder characterized by the childhood onset of motor and phonic tics, frequently accompanied by behavioral and psychiatric comorbidities. Existing treatments for tics raise safety concerns. In China, acupuncture has been a widely utilized approach for TS, and one specific traditional acupuncture method, plum-blossom needle therapy (PBNT), has exhibited favorable tolerance among pediatric patients. In this report, we present a case of TS treated using PBNT. CASE PRESENTATION: An 11-year-old boy diagnosed with Tourette syndrome for over five years presented with frequent loud throat clearing, eye blinking, severe abdominal tensing, shoulder shrugging, and upper limb twitching. Plum-blossom needle therapy (PBNT) was administered for 8 weeks, involving two sessions per week. The boy's tic symptoms gradually ameliorated, ultimately becoming minimal following the 8-week treatment period. Specifically, the Yale Global Tic Severity Scale (YGTSS) score decreased from 71 to 20, and the TS Clinical Global Impression Scale of Improvement (CGI-I) score reached 1, signifying 'very much improved' post-treatment. However, the Children and Adolescents' Quality of Life Scale (CAQOL) score exhibited minimal variation, moving from 146 to 150. CONCLUSION: This case suggests that plum-blossom needle therapy (PBNT) is well-tolerated by children and may be effective in alleviating tics associated with Tourette syndrome (TS). However, further research, particularly large-sample randomized controlled trials, is imperative to establish the efficacy and effectiveness of PBNT.

Association of Sustained Low or High Income and Income Changes With Risk of Incident Type 2 Diabetes Among Individuals Aged 30 to 64 Years.

Importance: Evidence of the association between income fluctuation and risk of type 2 diabetes (T2D) is scarce. Objective: To investigate whether sustained low or high income and income changes are associated with incidence of T2D. Design, Setting, and Participants: In this population-based cohort study, more than 7.8 million adults without T2D aged 30 to 64 years from a nationally representative sample from the Korean Health Insurance Service database were enrolled in 2012 and followed up to 2019 (median follow-up, 6.3 years [IQR, 6.1-6.6 years]). Exposures: Twenty quantiles of monthly health insurance premiums determined income levels. Income quartiles were annually analyzed from 2008 to 2012. Beneficiaries of the Medical Aid Program were regarded as those with very low income. A decrease in income was indicated as a reduction of 25% or more in income compared with income in the previous year. Main Outcomes and Measures: The primary outcome was incident T2D based on the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes E11 to E14, 1 or more claims of antidiabetic medication, or a fasting glucose level of 126 mg/dL or higher. Multivariable Cox proportional hazards models were used to assess the association of low- or high-income status and income changes with incidence of T2D. Results: Of 7 821 227 participants (mean [SD] age, 46.4 [9.3] years; 54.9% men), 359 931 (4.6%) developed T2D at least 1 year after enrollment. Individuals who repeatedly experienced low and very low income for 5 years showed 22% (hazard ratio [HR], 1.22 [95% CI, 1.21-1.23]) and 57% (1.57 [95% CI, 1.53-1.62]) higher T2D risk compared with those who never experienced low and very low income, respectively. In contrast, individuals who were repeatedly in high-income quartiles showed lower T2D risk compared with those who never experienced high income (HR, 0.86 [95% CI, 0.85-0.86]). The number of income decreases was associated with elevated T2D risk (≥2 vs 0 income decreases: HR, 1.08 [95% CI, 1.06-1.11]; P < .001 for trend). When income quartile status was compared between 2008 and 2012, individuals who experienced an income increase had lowered T2D risk, while those who experienced an income decrease had elevated T2D risk in each income quartile group. Conclusions and Relevance: This cohort study found that individuals who experienced sustained low-income status or an income decrease had elevated T2D risk, while those who had sustained high-income status or an income increase had lowered T2D risk.

Acupuncture for Low Back Pain: Reevaluation of Systematic Reviews and Meta-analyses.

PURPOSE OF REVIEW: This overview aims to reevaluate the methodological quality, report quality, and evidence quality of systematic reviews (SRs)/meta-analyses (MAs) of acupuncture for low back pain to determine whether acupuncture effectively treats low back pain (LBP). RECENT FINDINGS: Twenty-three SRs/MAs were deemed eligible for the present overview. The AMSTAR 2 score showed that the methodological quality of one SR/MA was of medium quality, one was of low quality, and 21 were of critically low quality. Based on the results of the PRISMA evaluation, there are certain areas for improvement in the quality of reporting of SRs/MAs. There were some reporting flaws in the topic of search strategy (8/23, 34.78%), certainty assessment (4/23, 17.39%), the certainty of evidence (4/23, 17.39%), registration and protocol (3/23, 13.04%), and availability of data, code, and other material (1/23, 4.35%). Results from the GRADE evaluation indicated that 13 of 255 outcomes were rated as moderate, 88 were low, and 154 were very low. Acupuncture effectively treated LBP in the SRs/MAs included in the reevaluation. However, the methodological, report, and evidence-based quality of the SRs/MAs on acupuncture for LBP was low. Therefore, further rigorous and comprehensive studies are warranted to improve the quality of SRs/MAs in this field.

A nomogram based on radiomics intermuscular adipose analysis to indicate arteriosclerosis in patients with newly diagnosed type 2 diabetes.

Objective: Early identifying arteriosclerosis in newly diagnosed type 2 diabetes (T2D) patients could contribute to choosing proper subjects for early prevention. Here, we aimed to investigate whether radiomic intermuscular adipose tissue (IMAT) analysis could be used as a novel marker to indicate arteriosclerosis in newly diagnosed T2D patients. Methods: A total of 549 patients with newly diagnosed T2D were included in this study. The clinical information of the patients was recorded and the carotid plaque burden was used to indicate arteriosclerosis. Three models were constructed to evaluate the risk of arteriosclerosis: a clinical model, a radiomics model (a model based on IMAT analysis proceeded on chest CT images), and a clinical-radiomics combined model (a model that integrated clinical-radiological features). The performance of the three models were compared using the area under the curve (AUC) and DeLong test. Nomograms were constructed to indicate arteriosclerosis presence and severity. Calibration curves and decision curves were plotted to evaluate the clinical benefit of using the optimal model. Results: The AUC for indicating arteriosclerosis of the clinical-radiomics combined model was higher than that of the clinical model [0.934 (0.909, 0.959) vs. 0.687 (0.634, 0.730), P < 0.001 in the training set, 0.933 (0.898, 0.969) vs. 0.721 (0.642, 0.799), P < 0.001 in the validation set]. Similar indicative efficacies were found between the clinical-radiomics combined model and radiomics model (P = 0.5694). The AUC for indicating the severity of arteriosclerosis of the combined clinical-radiomics model was higher than that of both the clinical model and radiomics model [0.824 (0.765, 0.882) vs. 0.755 (0.683, 0.826) and 0.734 (0.663, 0.805), P < 0.001 in the training set, 0.717 (0.604, 0.830) vs. 0.620 (0.490, 0.750) and 0.698 (0.582, 0.814), P < 0.001 in the validation set, respectively]. The decision curve showed that the clinical-radiomics combined model and radiomics model indicated a better performance than the clinical model in indicating arteriosclerosis. However, in indicating severe arteriosclerosis, the clinical-radiomics combined model had higher efficacy than the other two models. Conclusion: Radiomics IMAT analysis could be a novel marker for indicating arteriosclerosis in patients with newly diagnosed T2D. The constructed nomograms provide a quantitative and intuitive way to assess the risk of arteriosclerosis, which may help clinicians comprehensively analyse radiomics characteristics and clinical risk factors more confidently.

Effects of Electroacupuncture for Opioid-Induced Constipation in Patients With Cancer in China: A Randomized Clinical Trial.

Importance: Opioid-induced constipation (OIC) is prevalent among patients treated with opioids for cancer pain. Safe and effective therapies for OIC in patients with cancer remain an unmet need. Objective: To determine the efficacy of electroacupuncture (EA) for OIC in patients with cancer. Design, Setting, and Participants: This randomized clinical trial was conducted at 6 tertiary hospitals in China among 100 adult patients with cancer who were screened for OIC and enrolled between May 1, 2019, and December 11, 2021. Interventions: Patients were randomized to receive 24 sessions of EA or sham electroacupuncture (SA) over 8 weeks and then were followed up for 8 weeks after treatment. Main Outcomes and Measures: The primary outcome was the proportion of overall responders, defined as patients who had at least 3 spontaneous bowel movements (SBMs) per week and an increase of at least 1 SBM from baseline in the same week for at least 6 of the 8 weeks of the treatment period. All statistical analyses were based on the intention-to-treat principle. Results: A total of 100 patients (mean [SD] age, 64.4 [10.5] years; 56 men [56.0%]) underwent randomization; 50 were randomly assigned to each group. Among them, 44 of 50 patients (88.0%) in the EA group and 42 of 50 patients (84.0%) in the SA group received at least 20 (≥83.3%) sessions of treatment. The proportion of overall responders at week 8 was 40.1% (95% CI, 26.1%-54.1%) in the EA group and 9.0% (95% CI, 0.5%-17.4%) in the SA group (difference between groups, 31.1 percentage points [95% CI, 14.8-47.6 percentage points]; P < .001). Compared with SA, EA provided greater relief for most OIC symptoms and improved quality of life among patients with OIC. Electroacupuncture had no effects on cancer pain and its opioid treatment dosage. Electroacupuncture-related adverse events were rare, and, if any, all were mild and transient. Conclusions and Relevance: This randomized clinical trial found that 8-week EA treatment could increase weekly SBMs with a good safety profile and improve quality of life for the treatment of OIC. Electroacupuncture thus provided an alternative option for OIC in adult patients with cancer. Trial Registration: ClinicalTrials.gov Identifier: NCT03797586.

Microwave ablation for the management of pulmonary inflammatory myofibroblastic tumor: a case report and literature review.

Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor. Although IMT generally exhibits benign biological behavior, some IMT patients may develop local recurrence or even distant metastasis. Surgery is the most common therapeutic approach. However, additional treatment options are necessary for those who are unable to undergo surgical treatments. Microwave ablation (MWA) is a developing treatment option for unresectable lung cancer. Compared with radiofrequency ablation (RFA), MWA possesses many advantages including larger ablation zones, shorter heating times, and less susceptibility to heat sink. Herein, we reported the case of an 80-year-old male patient who presented with a mass in the right lower pulmonary lobe and right pleural effusion. The maximum diameter of the mass was 53.76 mm, and the patient's main complaint was fatigue for 2 months. Blood test showed severe anemia (hemoglobin: 79 g/L) and hypoproteinemia (albumin: 27.7 g/L). After undergoing blood transfusion, supplementation of albumin, thoracical puncturing and piping, the patient's nutritional condition was improved (hemoglobin, 95 g/L; serum albumin, 29.9 g/L). The pathological diagnosis was pulmonary IMT by percutaneous lung biopsy. The patient was successfully treated with three rounds of percutaneous MWA and has no evidence of recurrence nearly 3 years later. This case has expanded the therapeutic options for elderly patients with pulmonary IMT. Percutaneous MWA monotherapy might serve as an emerging treatment strategy for medically inoperable patients.

Anxiety of Older Persons Living Alone in the Community.

Anxiety is a common mental health problem among older persons, and the prevalence is higher in those who live alone than those who live with others. This study aimed to explore the experiences of anxiety in older persons living alone. A descriptive phenomenological approach was used to collect and analyze the interview data from 15 older persons (5 males, 10 females) living alone in Seoul, South Korea. Four main themes emerged from the data analysis: fear of being alone, concern about having an aged body, apprehension mixed with depression and loneliness, and fear of economic difficulties. These findings indicate that older persons living alone should receive continuous attention to prevent them from being neglected and their anxiety from worsening. Above all, it is vital to ensure comprehensive support for older persons living alone to alleviate their anxiety.

Measuring productivity of healthcare services under environmental constraints: evidence from China.

BACKGROUND: Despite the growing literature on the efficiency and productivity of the Chinese healthcare system, less attention has been given to examining the undesirable outputs linked to healthcare services, including environmental pollution. Taking the atmospheric environmental pollution resulting from the incineration of medical waste as an undesirable output of the healthcare system, this study analyzed the growth and decomposition of Total Factor Productivity (TFP) of healthcare services across 31 Chinese provinces during the period 2005-2016. METHODS: The Meta-frontier undesirable super-efficiency slack-based measure (SBM) model and the Global Malmquist-Luenberger (GML) Index were employed to analyze the growth and decomposition of TFP using the Max DEA software. RESULTS: The results revealed that the years 2009 and 2015 marked significant changes in TFP of healthcare services in Chinese provinces. During the study period, the rate of technological change (TC) slowly declined, whereas the rate of efficiency change (EC) steadily increased. With the national average being the benchmark, the results indicated that: the TFP of 17 provinces and cities exceeded the average, the EC of 16 provinces and cities exceeded the average, the TC of 9 provinces and cities exceeded the average, and the value in the Technology Gap Ratio (TGR) changes of 13 provinces and cities were above the national average. CONCLUSIONS: (1) The TFP of the healthcare services across China continued to decline slowly during the study period. (2) The effect of technical catch-up in the eastern, central, and western regions of China was significant across the three regions, whereas the effect of technical innovation was negative. (3) The TFP varied considerably among the Chinese provinces. These findings suggest that, under existing environmental constraints, relevant government departments should improve technical innovation in the supply of healthcare services and medical waste treatment, increase technical efficiency in the factor of healthcare production, strengthen regional health planning, and balance the development of regional healthcare.

Ecchymosis combined with postinflammatory hyperpigmentation associated with acupuncture therapy: An observational study of 167 subjects.

To evaluate the incidence of ecchymosis combined with postinflammatory hyperpigmentation (ECPH) over the course of 10 sessions of acupuncture therapy and to examine associated factors.An observational study was conducted from March 7, 2017 through March 6, 2018. This study included a total of 167 subjects and 326 bodily locations where acupuncture needles had been inserted. A 1-page questionnaire that included 14 items was used to collect patient data. The information collected was used to determine the incidence of ECPH. Chi-square tests were used to observe the associations between ECPH and demographic characteristics, dermatologic features, acupuncture-related factors, and other associated factors. Cox proportional hazards regression models were applied to calculate hazard ratios for ECPH among subjects treated with various frequencies of acupuncture and needles that differed in diameter.Although 186 subjects were initially enrolled, the study ultimately included 167 subjects and 326 bodily locations at which acupuncture needles were inserted. Over 10 sessions of acupuncture, ECPH was observed in 117 (70.06%, 117/167) subjects and 221 (67.79%, 221/326) bodily locations. Factors found to be associated with ECPH included: frequency of acupuncture, diameter of acupuncture needle, total number of acupuncture sessions, and bodily location at which acupuncture was administered (P < .05). Among subjects who received >2 acupuncture sessions per week, a higher frequency of acupuncture was associated with increased incidence of ECPH. Thicker acupuncture needle diameter was associated with a higher incidence of ECPH.The incidence of acupuncture-associated ECPH among the subjects included in the study was high. There were significant associations between ECPH and higher frequency of acupuncture as well as thicker diameter of acupuncture needles. Additional studies are required to confirm the findings.Trial registration number: AMCTR-OOC-17000109.

Tripartite Data Analysis for Optimizing Telemedicine Operations: Evidence from Guizhou Province in China.

Telemedicine is an innovative approach that helps alleviate the health disparity in developing countries and improve health service accessibility, affordability, and quality. Few studies have focused on the social and organizational issues involved in telemedicine, despite in-depth studies of and significant improvements in these technologies. This paper used evolutionary game theory to analyze behavioral strategies and their dynamic evolution in the implementation and operation of telemedicine. Further, numerical simulation was carried out to develop management strategies for promoting telemedicine as a new way of delivering health services. The results showed that: (1) When the benefits are greater than the costs, the higher medical institutions (HMIs), primary medical institutions (PMIs), and patients positively promote telemedicine with benign interactions; (2) when the costs are greater than the benefits, the stability strategy of HMIs, PMIs, and patients is, respectively, 'no efforts', 'no efforts', and 'non-acceptance'; and (3) promotion of telemedicine is influenced by the initial probability of the 'HMI efforts', 'PMI efforts', and 'patients' acceptance' strategy chosen by the three stakeholders, telemedicine costs, and the reimbursement ratio of such costs. Based on theoretical analysis, in order to verify the theoretical model, this paper introduces the case study of a telemedicine system integrated with health resources at provincial, municipal, county, and township level in Guizhou. The findings of the case study were consistent with the theoretical analysis. Therefore, the central Chinese government and local governments should pay attention to the running cost of MIs and provide financial support when the costs are greater than the benefits. At the same time, the government should raise awareness of telemedicine and increase participation by all three stakeholders. Lastly, in order to promote telemedicine effectively, it is recommended that telemedicine services are incorporated within the scope of medical insurance and the optimal reimbursement ratio is used.

Association between menstrual cycle irregularity and tinnitus: a nationwide population-based study.

This population-based cross-sectional study investigated the association between menstrual cycle irregularity and tinnitus in premenopausal Korean women. We used data from the 5th Korea National Health and Nutrition Examination Survey (2010-2012). A total of 4633 premenopausal women were included. Hierarchical multivariable logistic regression analysis was performed. Individuals with tinnitus accounted for 21.6%. Women with tinnitus or menstrual irregularity had significantly higher rates of stress, depressive mood, and suicidal ideation than those without. The proportion of individuals with irregular menstrual cycles with duration of longer than 3 months increased as the severity of tinnitus increased (P = 0.01). After adjusting for confounding variables, the odds of tinnitus increased in individuals with irregular menstrual cycles compared to those with regular menstrual cycles. The odds ratios (ORs) of tinnitus tended to increase as the duration of menstrual irregularity became longer (1.37, 95% confidence interval: 1.06-1.78 for duration of up to 3 months; 1.71, 1.03-2.85 for duration of longer than 3 months, P for trend = 0.002). Our study found a positive association between menstrual cycle irregularity and tinnitus. Menstrual cycle irregularity may be a related factor of tinnitus in women with childbearing age.

Electroacupuncture Versus Pelvic Floor Muscle Training Plus Solifenacin for Women With Mixed Urinary Incontinence: A Randomized Noninferiority Trial.

OBJECTIVE: To evaluate the efficacy and safety of electroacupuncture vs pelvic floor muscle training (PFMT) plus solifenacin for women with mixed urinary incontinence (MUI). PATIENTS AND METHODS: This randomized controlled noninferiority trial was conducted at 10 hospitals in China between March 1, 2014, and October 10, 2016. Participants were randomized 1:1 to receive electroacupuncture (36 sessions) over 12 weeks with 24 weeks of follow-up or PFMT-solifenacin (5 mg/d) over 36 weeks. The primary outcome was percentage change from baseline to week 12 in mean 72-hour incontinence episode frequency (IEF) measured by the 72-hour bladder diary. It was analyzed in the per-protocol set with a prespecified noninferiority margin of 15%. RESULTS: Of 500 women with MUI who were randomized, 467 (239 in the electroacupuncture group and 228 in the PFMT-solifenacin group) completed treatment per protocol and were included in the primary outcome analysis. At weeks 1 through 12, the percentage of reduction from baseline in mean 72-hour IEF was 37.83% in the electroacupuncture group and 36.49% in the PFMT-solifenacin group (between-group difference, -1.34% [95% CI, -9.78% to 7.10%]; P<.001 for noninferiority), which demonstrates noninferiority; the treatment effect persisted throughout follow-up. Statistically significant improvements were found for secondary outcomes in both groups, with no meaningful difference between treatments. CONCLUSION: In women with moderate to severe MUI, electroacupuncture was not inferior to PFMT-solifenacin in decreasing the 72-hour IEF and shows promise as an effective alternative for the treatment of MUI.

The moderating role of the amount of caregiving tasks on the relationships between dementia caregivers' characteristics and outcomes.

AIM: This study identified the moderating role of the amount of caregiving tasks on relationships between dementia family caregivers' characteristics (age, education, etc.) and outcomes (burden, etc.). DESIGN: A cross-sectional analysis of surveyed data. METHOD: A convenience sample of 369 family caregivers (151 males, 218 females) aged 20 years or older was recruited from 10 cities in the southern area of South Korea. Data were collected from November-December 2011. Measures of caregiver burden, perceived health status and emotional distress of caregivers related to the memory-behaviour problems of the care recipient were used to assess the outcomes of family caregivers of older adults with dementia. RESULTS: The amount of caregiving tasks has a moderating effect on the relationships between caregivers' characteristics (such as living with the recipient and duration of caregiving) and the caregiver burden. The interaction between the amount of caregiving tasks and status of living with recipient was significant in relation to the emotional distress of caregivers related to the memory-behaviour problems of the care recipient with dementia; however, there was no effect of the amount of caregiving tasks on the relationships between caregivers' characteristics and perceived health status. CONCLUSION: The amount of caregiving tasks can have a moderating role in the caregiving stress model. Intervention programs need to be developed and implemented to reduce negative outcomes of family caregivers, particularly those living with older adults with dementia.

Predicting epidermal growth factor receptor gene amplification status in glioblastoma multiforme by quantitative enhancement and necrosis features deriving from conventional magnetic resonance imaging.

To study whether some of the quantitative enhancement and necrosis features in preoperative conventional MRI (cMRI) had a predictive value for epidermal growth factor receptor (EGFR) gene amplification status in glioblastoma multiforme (GBM).Fifty-five patients with pathologically determined GBMs who underwent cMRI were retrospectively reviewed. The following cMRI features were quantitatively measured and recorded: long and short diameters of the enhanced portion (LDE and SDE), maximum and minimum thickness of the enhanced portion (MaxTE and MinTE), and long and short diameters of the necrotic portion (LDN and SDN). Univariate analysis of each feature and a decision tree model fed with all the features were performed. Area under the receiver operating characteristic (ROC) curve (AUC) was used to assess the performance of features, and predictive accuracy was used to assess the performance of the model.For single feature, MinTE showed the best performance in differentiating EGFR gene amplification negative (wild-type) (nEGFR) GBM from EGFR gene amplification positive (pEGFR) GBM, and it got an AUC of 0.68 with a cut-off value of 2.6 mm. The decision tree model included 2 features MinTE and SDN, and got an accuracy of 0.83 in validation dataset.Our results suggest that quantitative measurement of the features MinTE and SDN in preoperative cMRI had a high accuracy for predicting EGFR gene amplification status in GBM.

Acupuncture for adults with overactive bladder: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Overactive bladder is stated as the occurrence of urinary urgency which will cause negative impacts and decrease patients' health-related quality of life. The aim of this systematic review is to assess the efficiency and safety of acupuncture for adults with overactive bladder (OAB) comparing with sham-acupuncture, drugs, and acupuncture plus drugs. METHODS: We independently searched 9 databases from beginning to August 15, 2017. Two writers extracted data at the same time independently. Study outcomes were calculated by standardized mean differences (SMD) with 95% confidence intervals (CIs) and mean difference (MD) with 95% CIs. RESULTS: Ten randomized controlled trials (RCTs) with 794 patients were included in this systematic review. The combined results showed that electroacupuncture (EA) may be more effective than sham electroacupuncture (sham EA) in improving the 24-hour nocturia episodes and EA may enhance tolterodine for relieving voiding symptoms and enhancing patients' quality of life. However, more trials with high quality and larger sample sizes will be needed in the future to provide sufficient evidence. Only 15 of 794 OAB patients from the included studies reported mild adverse reactions related to EA, therefore, acupuncture is safe for treating OAB. CONCLUSION: Acupuncture might have effect in decreasing the number of micturition episodes, incontinence episodes, and nocturia episodes. However, the evidence is insufficient to show the effect using acupuncture alone or the additional effect to drugs in treating OAB.

Efficacy of acupuncture on menstrual frequency in women with polycystic ovary syndrome: Protocol for a randomized, controlled trial.

BACKGROUND: Acupuncture may improve the menstrual frequency of women with polycystic ovary syndrome (PCOS). However, more sufficient data are needed to improve the efficacy of acupuncture. METHODS: A total of 172 participants diagnosed with PCOS would be randomly assigned to either the acupuncture group or sham-acupuncture group, at a ratio of 1:1. Participants in both groups will receive treatment for 12 weeks, 3 times a week. The primary outcome will be the proportion of participants with at least a 50% increase from baseline in the monthly menstrual frequency from baseline after 12 weeks intervention, while secondary outcomes will be the difference in anthropometrics, serum hormone level, ovarian morphology, anxiety and depression, and quality of life from baseline to after 12 weeks intervention and to 12 weeks postintervention follow-up between groups. DISCUSSION: The aim of this study is to evaluate the efficacy and safety of acupuncture for improving menstrual frequency and other symptoms of patients with PCOS. The limitation of this trial is that it would be difficult to blind the acupuncturists. In addition, these findings may not be suitable for women with PCOS who are seeking pregnancy.

Acupuncture for Tourette Syndrome: A Systematic Review.

Tourette syndrome (TS) is a neuropsychiatric disorder that affects both children and adults. We searched for randomised controlled trials (RCTs) using acupuncture to treat TS written in English or Chinese without restrictions on publication status. Study selection, data extraction, and assessment of study quality were conducted independently by two reviewers. Meta-analyses were performed using Review Manager (RevMan) 5.3 software from the Cochrane Collaboration. Data were combined with the fixed-effect model based on a heterogeneity test. Results were presented as risk ratios for dichotomous data and mean differences (MDs) for continuous data. This review included 7 RCTs with a total of 564 participants. The combined results showed that acupuncture may have better short-term effect than Western medicine for TS and that acupuncture may be an effective adjuvant therapy in improving the effect of Western medicine on TS, but the evidence is limited because of existing biases. Rigorous high-quality RCTs are needed to verify these findings.

Electroacupuncture for reproductive hormone levels in patients with diminished ovarian reserve: a prospective observational study.

BACKGROUND: Effective methods for the treatment of reproductive dysfunction are limited. Previous studies have reported that acupuncture can modulate female hormone levels, improve menstrual disorders, alleviate depression and improve pregnancy rates. However, studies of acupuncture for diminished ovarian reserve (DOR) are lacking. OBJECTIVE: To carry out a prospective observational study aimed at assessing the effect of EA on the reproductive hormone levels of patients with DOR seeking fertility support and consider its safety. METHODS: Eligible patients with DOR received EA for 12 weeks: five times a week for 4 weeks followed by three times a week for 8 weeks. The primary outcome was the change in mean follicle-stimulating hormone (FSH) level at week 12. Mean luteinising hormone (LH) and serum oestradiol (E2) levels, FSH/LH ratios and symptom scale scores were simultaneously observed. RESULTS: Twenty-one patients with DOR were included in the final analysis. Mean FSH levels fell from 19.33±9.47 mIU/mL at baseline to 10.58±6.34 mIU/mL at week 12 and 11.25±6.68 mIU/mL at week 24. Change in mean FSH from baseline was -8.75±11.13 mIU/mL at week 12 (p=0.002) and -8.08±9.56 mIU/mL at week 24 (p=0.001). Mean E2 and LH levels, FSH/LH ratios and irritability scores were improved at weeks 12 and/or 24. Approximately 30% patients reported subjective increases in menstrual volume after treatment. CONCLUSIONS: EA may modulate reproductive hormone levels and the effects seem to persist for at least 12 weeks after treatment with no significant side effects. EA may improve the ovarian reserve of patients with DOR, though further research is needed. TRIAL REGISTRATION NUMBER: NCT02229604; Results.
