Examining the influence of body fat distribution on standing balance and functional performance in overweight female patients with degenerative lumbar disease.

Introduction: Degenerative lumbar disease (DLD) is a prevalent disorder that predominantly affects the elderly population, especially female. Extensive research has demonstrated that overweight individuals (categorized by body fat distribution) have a higher susceptibility to developing DLD and an increased risk of falling. However, there is limited research available on the standing balance and functional performance of overweight females with DLD. Aims: To determine the impact of body fat distribution on standing balance and functional performance in overweight females with DLD. Methods: This cross-sectional study evaluated thirty females with DLD were categorized into three types of body fat distribution based on body mass index (BMI) and waist-hip ratio, specifically as android-type, gynoid-type, and normal weight groups. In addition, a control group of ten age-matched females with normal weight was recruited. The Visual Analogue Scale, Roland Morris Disability Questionnaire, Cobb angle (Determined using x-ray), and body composition (Determined using the InBody S10), were conducted only on the DLD groups. All participants were assessed standing balance in the anteroposterior and mediolateral directions. The functional assessments included timed-up-and-go and 5-times-sit-to-stand tests. Results: There were 10 people in each group. Android-type (Age = 65.00 ± 6.34 years; BMI = 26.87 ± 2.05 kg/m2), Gynoid-type (Age = 65.60 ± 4.99 years; BMI = 26.60 ± 1.75 kg/m2), Normal weight (Age = 65.70 ± 5.92 years; BMI = 22.35 ± 1.26 kg/m2), and Control (Age = 65.00 ± 5.23 years; BMI = 22.60 ± 1.12 kg/m2). The android-type group had higher body fat, visceral fat, and lower muscle mass (p < 0.05), along with an increased Cobb angle (p < 0.05). They showed greater ellipse area, total excursion, and mean distance in the anteroposterior direction (p < 0.05). During the functional performance assessments, the android-type group had longer durations in both the 5-times-sit-to-stand and timed-up-and-go tasks (p < 0.05). Conclusion: Our study found that android-type overweight individuals showed postural instability, reduced functional performance, and insufficient lower limb muscle strength and mass. These findings might help physical therapists in planning interventions, as they imply that patients with DLD may require specific types of standing balance training and lower extremities muscle-strengthening based on their body fat distribution.

Development of a Novel Endometrial Signature Based on Endometrial microRNA for Determining the Optimal Timing for Embryo Transfer.

Though tremendous advances have been made in the field of in vitro fertilization (IVF), a portion of patients are still affected by embryo implantation failure issues. One of the most significant factors contributing to implantation failure is a uterine condition called displaced window of implantation (WOI), which refers to an unsynchronized endometrium and embryo transfer time for IVF patients. Previous studies have shown that microRNAs (miRNAs) can be important biomarkers in the reproductive process. In this study, we aim to develop a miRNA-based classifier to identify the WOI for optimal time for embryo transfer. A reproductive-related PanelChip® was used to obtain the miRNA expression profiles from the 200 patients who underwent IVF treatment. In total, 143 out of the 167 miRNAs with amplification signals across 90% of the expression profiles were utilized to build a miRNA-based classifier. The microRNA-based classifier identified the optimal timing for embryo transfer with an accuracy of 93.9%, a sensitivity of 85.3%, and a specificity of 92.4% in the training set, and an accuracy of 88.5% in the testing set, showing high promise in accurately identifying the WOI for the optimal timing for embryo transfer.

Opportunistic screening for coronary artery calcium deposition using chest radiographs - a multi-objective models with multi-modal data fusion.

Background: To create an opportunistic screening strategy by multitask deep learning methods to stratify prediction for coronary artery calcium (CAC) and associated cardiovascular risk with frontal chest x-rays (CXR) and minimal data from electronic health records (EHR). Methods: In this retrospective study, 2,121 patients with available computed tomography (CT) scans and corresponding CXR images were collected internally (Mayo Enterprise) with calculated CAC scores binned into 3 categories (0, 1-99, and 100+) as ground truths for model training. Results from the internal training were tested on multiple external datasets (domestic (EUH) and foreign (VGHTPE)) with significant racial and ethnic differences and classification performance was compared. Findings: Classification performance between 0, 1-99, and 100+ CAC scores performed moderately on both the internal test and external datasets, reaching average f1-score of 0.66 for Mayo, 0.62 for EUH and 0.61 for VGHTPE. For the clinically relevant binary task of 0 vs 400+ CAC classification, the performance of our model on the internal test and external datasets reached an average AUCROC of 0.84. Interpretation: The fusion model trained on CXR performed better (0.84 average AUROC on internal and external dataset) than existing state-of-the-art models on predicting CAC scores only on internal (0.73 AUROC), with robust performance on external datasets. Thus, our proposed model may be used as a robust, first-pass opportunistic screening method for cardiovascular risk from regular chest radiographs. For community use, trained model and the inference code can be downloaded with an academic open-source license from https://github.com/jeong-jasonji/MTL_CAC_classification . Funding: The study was partially supported by National Institute of Health 1R01HL155410-01A1 award.

Percutaneous transluminal angioplasty and stenting of post-irradiated stenosis of subclavian artery: A matched case-control study.

BACKGROUND: Although radiotherapy is common for head/neck and chest cancers (HNCC), it can result in post-irradiation stenosis of the subclavian artery (PISSA). The efficacy of percutaneous transluminal angioplasty and stenting (PTAS) to treat severe PISSA is not well-clarified. AIMS: To compare the technical safety and outcomes of PTAS between patients with severe PISSA (RT group) and radiation-naïve counterparts (non-RT group). METHODS: During 2000 and 2021, we retrospectively enrolled patients with severe symptomatic stenosis (>60%) of the subclavian artery who underwent PTAS. The rate of new recent vertebrobasilar ischaemic lesions (NRVBIL), diagnosed on diffusion-weight imaging (DWI) within 24 h of postprocedural brain MRI; symptom relief; and long-term stent patency were compared between the two groups. RESULTS: Technical success was achieved in all 61 patients in the two groups. Compared with the non-RT group (44 cases, 44 lesions), the RT group (17 cases, 18 lesions) had longer stenoses (22.1 vs 11.1 mm, P = 0.003), more ulcerative plaques (38.9% vs 9.1%, P = 0.010), and more medial- or distal-segment stenoses (44.4% vs 9.1%, P<0.001). The technical safety and outcome between the non-RT group and the RT group were NRVBIL on DWI of periprocedural brain MRI 30.0% vs 23.1%, P = 0.727; symptom recurrence rate (mean follow-up 67.1 ± 50.0 months) 2.3% vs 11.8%, P = 0.185; and significant in-stent restenosis rate (>50%) 2.3% vs 11.1%, P = 0.200. CONCLUSION: The technical safety and outcome of PTAS for PISSA were not inferior to those of radiation-naïve counterparts. PTAS for PISSA is an effective treatment for medically refractory ischaemic symptoms of HNCC patients with PISSA.

High-fat diet induces C-reactive protein secretion, promoting lung adenocarcinoma via immune microenvironment modulation.

To understand the effects of a high-fat diet (HFD) on lung cancer progression and biomarkers, we here used an inducible mutant epidermal growth factor receptor (EGFR)-driven lung cancer transgenic mouse model fed a regular diet (RD) or HFD. The HFD lung cancer (LC-HFD) group exhibited significant tumor formation and deterioration, such as higher EGFR activity and proliferation marker expression, compared with the RD lung cancer (LC-RD) group. Transcriptomic analysis of the lung tissues revealed that the significantly changed genes in the LC-HFD group were highly enriched in immune-related signaling pathways, suggesting that an HFD alters the immune microenvironment to promote tumor growth. Cytokine and adipokine arrays combined with a comprehensive analysis using meta-database software indicated upregulation of C-reactive protein (CRP) in the LC-HFD group, which presented with increased lung cancer proliferation and metastasis; this was confirmed experimentally. Our results imply that an HFD can turn the tumor growth environment into an immune-related pro-tumorigenic microenvironment and demonstrate that CRP has a role in promoting lung cancer development in this microenvironment.

Self-Assembly of Hemimyzon Formosanus-Inspired Crescent-Shaped Nanosucker Arrays for Reversible Adhesion.

Hemimyzon formosanus, a species of ray-finned fish, makes use of crescent-shaped abdominal suckers for adhering to irregular, rough, and slippery gravel in fast-flowing headwaters and minor tributaries. Bioinspired by the adhesion characteristics, two-dimensional non-close-packed colloidal crystals are self-assembled and serve as templates to pattern crescent-shaped shape memory polymer-based nanostructure arrays. By the manipulation of the configuration of nanosuckers through applying common solvent stimulations, the corresponding adhesion performances on glass, sandpaper, or even porcine kidney surfaces can be switched instantaneously and reversibly under ambient conditions. The biomimetic nanostructures indicate possible solutions to a variety of challenges, such as wound nursing, and so on.

Infrared Spectra of (Z)- and (E)-•CH2C(CH3)CHI Radicals Produced upon Photodissociation of (Z)- and (E)-(CH2I)(CH3)C═CHI in Solid para-Hydrogen.

Ozonolysis of isoprene is important in atmospheric chemistry because of the abundant emission of isoprene. This process produces the Criegee intermediates CH2OO, methyl vinyl ketone oxide (MVKO, C2H3C(CH3)OO), and methacrolein oxide (MACRO, CH2C(CH3)CHOO). Gaseous MACRO was recently produced and identified in laboratories after photolysis of a mixture of 1,3-diiodo-2-methyl-prop-1-ene [(CH2I)(CH3)C═CHI] and O2, but the conformation-dependent formation mechanism remains unexplored. We report conformation-distinct IR spectra of (E)- and (Z)-(CH2I)(CH3)C═CHI isolated in solid p-H2. Upon irradiation near 300 nm of (E)- and (Z)-(CH2I)(CH3)C═CHI in solid p-H2 at 3.3 K, 3-iodo-2-methyl-prop-1-en-3-yl [•CH2C(CH3)CHI] radicals were characterized, with intense infrared absorption lines at 2991.3, 1458.7, 1434.7, 1317.4, 1190.4, 786.3, 677.9, and 467.2 cm-1 and additional 11 weaker ones assigned to (E)-•CH2C(CH3)CHI and intense lines at 3108.5, 3076.2, 3028.5, 2970.0, 1174.2, 796.0, 683.6, and 609.5 cm-1 and additional 7 weaker ones to (Z)-•CH2C(CH3)CHI. The assignments were derived according to the behaviors of secondary photolysis at 495 and 460 nm and a comparison of the vibrational wavenumbers and IR intensities of the observed lines with those calculated with the B2PLYP-D3/aug-cc-pVTZ-pp method. These observations confirm that only the allylic C-I bond, not the vinylic one, was photodissociated at 290 nm, and in solid p-H2, the excess energy upon photolysis induced no conformational change. When O2 was present in the matrix, several intense lines at 1147.5, 1025.7, 914.4, and 728.7 cm-1, and 4 weaker ones were tentatively assigned to the adduct CH2C(CH3)CHIOO; the assignments were supported by 18O2 isotopic experiments. Unlike in the gaseous phase, the remaining C-I bond of this adduct could not break to form MACRO because of the efficient quenching in a low-temperature matrix.

Rapid and sensitive dilute-and-shoot analysis using LC-MS-MS for identification of multi-class psychoactive substances in human urine.

The emergence of new psychoactive substances currently exceeding a thousand is rapidly changing substance prevalence patterns and straining the methods used for detection, most of which are suitable only for a single class of substances. This study presents a rapid and facile dilute-and-shoot system operated in conjunction with an optimized liquid chromatographic separation system for the high-sensitivity detection of substances across a range of substance classes with 3 isotopes used only. The proposed method based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) is able to identify 68 substance and their metabolites in urine samples as small as 50 µL. Optimal chromatographic conditions including 95% water/methanol ratio with 0.1% added formic acid and a prolonged LC gradient run-time (15 min) improved the peak shape of polar compounds and enhanced signal strength by 5%. Under 4-fold dilution, all analytes were within 80-120% of tolerance response levels, indicating that the matrix effect was insignificant. In experiments, the limit of detection (LOD) ranged from 0.05 to 0.5 ng mL-1, while the coefficient of determination (R2) was > 0.9950. The retention time shift of each peak remained at < 2% with an inter-day relative standard deviation (RSD) of 0.9-14.9% and intra-day RSD of 1.1%- 13.8%. The rapid dilute-and-shoot presents a high-sensitivity, significant stability, robustness and reproducibility without serious interference. To demonstrate the effectiveness of the system, 532 urine samples were collected from suspected drug abusers, and the proposed method was used for rapid analysis. Of these samples, 79.5% contained between one and twelve analytes, and 12.4% tested positive for new psychoactive substances, mostly derivatives of amphetamine and synthetic cathinones. The study presents a high-sensitivity analytic system that is capable of detecting substances from multiple classes and can be used for effective monitoring of substance prevalence in urine.

LCRMP-1 is required for spermatogenesis and stabilises spermatid F-actin organization via the PI3K-Akt pathway.

Long-form collapsin response mediator protein-1 (LCRMP-1) belongs to the CRMP family which comprises brain-enriched proteins responsible for axon guidance. However, its role in spermatogenesis remains unclear. Here we find that LCRMP-1 is abundantly expressed in the testis. To characterize its physiological function, we generate LCRMP-1-deficient mice (Lcrmp-1-/-). These mice exhibit aberrant spermiation with apoptotic spermatids, oligospermia, and accumulation of immature testicular cells, contributing to reduced fertility. In the seminiferous epithelial cycle, LCRMP-1 expression pattern varies in a stage-dependent manner. LCRMP-1 is highly expressed in spermatids during spermatogenesis and especially localized to the spermiation machinery during spermiation. Mechanistically, LCRMP-1 deficiency causes disorganized F-actin due to unbalanced signaling of F-actin dynamics through upregulated PI3K-Akt-mTOR signaling. In conclusion, LCRMP-1 maintains spermatogenesis homeostasis by modulating cytoskeleton remodeling for spermatozoa release.

Percutaneous transluminal angioplasty and stenting of post-irradiation stenosis of the vertebral artery.

BACKGROUND: The outcomes of percutaneous transluminal angioplasty and stenting (PTAS) in patients with medically refractory post-irradiation stenosis of the vertebral artery (PISVA) have not been clarified. AIM: This retrospective study evaluated the safety and outcomes of PTAS in patients with severe PISVA compared with their radiation-naïve counterparts (non-RT group). METHODS: Patients with medically refractory severe symptomatic vertebral artery stenosis and undergoing PTAS between 2000 and 2021 were classified as the PISVA group or the non-RT group. The periprocedural neurological complications, periprocedural brain magnetic resonance imaging, the extent of symptom relief, and long-term stent patency were compared. RESULTS: As compared with the non-RT group (22 cases, 24 lesions), the PISVA group (10 cases, 10 lesions) was younger (62.0 ± 8.6 vs 72.4 ± 9.7 years, P = 0.006) and less frequently had hypertension (40.0% vs 86.4%, P = 0.013) and diabetes mellitus (10.0% vs 54.6%, P = 0.024). Periprocedural embolic infarction was not significantly different between the non-RT group and the PISVA group (37.5% vs 35.7%, P = 1.000). At a mean follow-up of 72.1 ± 58.7 (3-244) months, there was no significant between-group differences in the symptom recurrence rate (0.00% vs 4.55%, P = 1.000) and in-stent restenosis rate (10.0% vs 12.5%, P = 1.000). CONCLUSION: PTAS of severe medically refractory PISVA is effective in the management of vertebrobasilar ischemic symptoms in head and neck cancer patients. Technical safety and outcome of the procedure were like those features in radiation-naïve patients.

Early cholecystectomy following percutaneous transhepatic gallbladder drainage is effective for moderate to severe acute cholecystitis in the octogenarians.

BACKGROUND: Acute cholecystitis (AC) is a life-threatening infectious/inflammatory disease in older patients. This study aimed to investigate the safety and optimal timing of surgery in patients aged ≥ 80 years with moderate to severe AC who received percutaneous transhepatic gallbladder drainage (PTGBD). METHODS: From January 2008 to February 2021, 152 patients were retrospectively enrolled. Clinical outcomes were compared among patients who received laparoscopic cholecystectomy (LC), open cholecystectomy (OC), and conversion surgery, and between those who received early (< 6 weeks after PTGBD) and delayed cholecystectomy (≥ 6 weeks after PTGBD). Logistic regression analysis was used to identify risk factors for recurrent AC, further biliary events, conversion, and perioperative complications. RESULTS: Sixty-seven patients underwent LC, 62 underwent OC, and 23 underwent conversion surgery. Operation-related complications and mortality rates did not differ among the types of surgery; however, LC group had shorter operative time than the other groups. Eighty-two patients underwent early cholecystectomy, while 70 underwent delayed cholecystectomy. There were no differences in operative time, operation-related complications, and mortality rates between the groups. However, higher rates of recurrent AC and biliary events were observed in the delayed cholecystectomy group (52.9% vs. 4.9% and 57.1% vs. 8.5%, p < 0.001). On multivariate analysis, delayed cholecystectomy was a significant risk factor for recurrent AC (odds ratio [OR] = 19.42, p < 0.001) and further biliary events (OR = 15.95, p < 0.001). CONCLUSIONS: Early cholecystectomy is recommended for patients aged ≥ 80 years with moderate to severe AC following PTGBD.

ATM- and ATR-induced primary ciliogenesis promotes cisplatin resistance in pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers because of its late diagnosis and chemoresistance. Primary cilia, the cellular antennae, are observed in most human cells to maintain development and differentiation. Primary cilia are gradually lost during the progression of pancreatic cancer and are eventually absent in PDAC. Here, we showed that cisplatin-resistant PDAC regrew primary cilia. Additionally, genetic or pharmacological disruption of primary cilia sensitized PDAC to cisplatin treatment. Mechanistically, ataxia telangiectasia mutated (ATM) and ATM and RAD3-related (ATR), tumor suppressors that initiate DNA damage responses, promoted the excessive formation of centriolar satellites (EFoCS) and autophagy activation. Disruption of EFoCS and autophagy inhibited primary ciliogenesis, sensitizing PDAC cells to cisplatin treatment. Collectively, our findings revealed an unexpected interplay among the DNA damage response, primary cilia, and chemoresistance in PDAC and deciphered the molecular mechanism by which ATM/ATR-mediated EFoCS and autophagy cooperatively regulate primary ciliogenesis.

The Reliability and Validity of the Mandarin Chinese Version of the Vocal Fatigue Index: Preliminary Validation.

PURPOSE: This study attempted to develop and to preliminarily validate the Mandarin Chinese version of the Vocal Fatigue Index (VFI) as a standardized self-assessment questionnaire tool for potential clinical applications. METHOD: The experimental procedure involved (a) cross-cultural adaptation of the VFI into the Mandarin Chinese version (CVFI), (b) evaluation by an expert panel, (c) back translation, (d) pilot testing, and (e) validation of the questionnaire by three participant groups: 50 with voice disorders, 50 occupational voice users (at-risk group), and 50 with normal voice (control group). Internal consistency, test-retest reliability, content validity, and convergent validity of the CVFI were examined, and discriminatory ability (diagnostic accuracy) for distinguishing between the groups was evaluated. RESULTS: Results showed high internal consistency (Cronbach's alpha ≥ .8817 for the total CVFI scores for all groups), high test-retest reliability (intraclass correlation coefficients ≥ .9072, p < .001 for the total CVFI scores for all groups), high content validity (total content validity index = 0.9368), and high convergent validity (Pearson r ≥ .8155, p < .001 between the total CVFI scores and Factors 1 and 2 scores). Significant differences between the three groups were found in all scores. Receiver operating characteristic analysis revealed a high diagnostic accuracy for distinguishing between the disorders group and the normal group (area under the curve ≥ 0.927, p < .001 for the total CVFI scores and Factors 1 and 2 scores), with cutoff scores of ≥ 36 (total CVFI score), ≥ 23.5 (Factor 1 score), ≥ 7.5 (Factor 2 score), and ≤ 6.5 (Factor 3 score). CONCLUSIONS: These findings suggested that the CVFI could be a reliable and valid self-assessment tool for the clinical evaluation of vocal fatigue in Mandarin Chinese-speaking populations. A full-scale validation study of the CVFI is recommended to verify these results.

Chemical Exchange Saturation Transfer (CEST) Signal at -1.6 ppm and Its Application for Imaging a C6 Glioma Model.

The chemical exchange saturation transfer (CEST) signal at -1.6 ppm is attributed to the choline methyl on phosphatidylcholines and results from the relayed nuclear Overhauser effect (rNOE), that is, rNOE(-1.6). The formation of rNOE(-1.6) involving the cholesterol hydroxyl is shown in liposome models. We aimed to confirm the correlation between cholesterol content and rNOE(-1.6) in cell cultures, tissues, and animals. C57BL/6 mice (N = 9) bearing the C6 glioma tumor were imaged in a 7 T MRI scanner, and their rNOE(-1.6) images were cross-validated through cholesterol staining with filipin. Cholesterol quantification was obtained using an 18.8-T NMR spectrometer from the lipid extracts of the brain tissues from another group of mice (N = 3). The cholesterol content in the cultured cells was manipulated using methyl-ß-cyclodextrin and a complex of cholesterol and methyl-ß-cyclodextrin. The rNOE(-1.6) of the cell homogenates and their cholesterol levels were measured using a 9.4-T NMR spectrometer. The rNOE(-1.6) signal is hypointense in the C6 tumors of mice, which matches the filipin staining results, suggesting that their tumor region is cholesterol deficient. The tissue extracts also indicate less cholesterol and phosphatidylcholine contents in tumors than in normal brain tissues. The amplitude of rNOE(-1.6) is positively correlated with the cholesterol concentration in the cholesterol-manipulated cell cultures. Our results indicate that the cholesterol dependence of rNOE(-1.6) occurs in cell cultures and solid tumors of C6 glioma. Furthermore, when the concentration of phosphatidylcholine is carefully considered, rNOE(-1.6) can be developed as a cholesterol-weighted imaging technique.

Anticonvulsive and Neuroprotective Effects of Eupafolin in Rats Are Associated with the Inhibition of Glutamate Overexcitation and Upregulation of the Wnt/ß-Catenin Signaling Pathway.

Several plant compounds have been found to possess neuroactive properties. The aim of this study was to investigate the anticonvulsant effect of eupafolin, a major active component extracted from Salvia plebeia, a herb used in traditional medicine for its anti-inflammatory properties. To this end, we assessed the anticonvulsant effects of eupafolin in rats intraperitoneally (i.p.) injected with kainic acid (KA) to elucidate this mechanism. Treatment with eupafolin (i.p.) for 30 min before KA administration significantly reduced behavioral and electrographic seizures induced by KA, similar to carbamazepine (i.p.), a widely used antiepileptic drug. Eupafolin treatment also significantly decreased KA seizure-induced neuronal cell death and glutamate elevation in the hippocampus. In addition, eupafolin notably reversed KA seizure-induced alterations in α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor subunit GluR2, glutamate decarboxylase 67 (GAD67, GABAergic enzyme), and Wnt signaling-related proteins, including porcupine, Wnt1, phosphorylated-glycogen synthase kinase-3ß, ß-catenin, and Bcl-2 in the hippocampus. Furthermore, the increased level of Dickkopf-related protein 1 (Dkk-1, a Wnt signaling antagonist) and the decreased level of Disheveled1 (Dvl-1, a Wnt signaling activator) in the hippocampus of KA-treated rats were reversed by eupafolin. This study provides evidence of the anticonvulsant and neuroprotective properties of eupafolin and of the involvement of regulation of glutamate overexcitation and Wnt signaling in the mechanisms of these properties. These findings support the benefits of eupafolin in treating epilepsy.

Preserving residual renal function: Is interdialytic acupuncture an add-on option? A case series report.

BACKGROUND: Whether acupuncture therapy contributes to preserving residual renal function (RRF) remains largely unknown. This case series demonstrated the potential beneficial effects of acupuncture for preserving RRF in five patients with end-stage renal disease undergoing hemodialysis (HD) treatment. PARTICIPANTS: HD patients received eight sessions of weekly 30 min interdialytic acupuncture (Inter-A) at ten selected acupoints, namely Yintang (GV29), Yingxiang (LI20), Shuijin (Tung's Acupuncture), Lianquan (CV23), Shangqu (KI17), Tianshu (ST25), Siman (KI14), Hegu (LI4), Zusanli (ST36) and Sanyingjao (SP6). Residual urine volume (rUV) and residual glomerular filtration rate (rGFR) were recorded once every two weeks Outcomes: Changes in rUV and rGFR were calculated using 24 h urine collection data to assess RRF. Variations in hemoglobin, urea Kt/V and serum albumin levels were measured monthly to evaluate HD adequacy. RESULTS: After eight Inter-A sessions, the mean[standard deviation] rUV and rGFR increased from 612[184] ml/day and 1.48[0.94] ml/min/1.73 m2 at baseline to the peak of 803[289] ml/day and 2.04[1.17] ml/min/1.73 m2 at 2- and 4-week follow-up, respectively. The mean percentage difference increased by 31% in the rUV and 37% in the rGFR. Routine measurements of HD adequacy also showed improvements. CONCLUSIONS: Acupuncture might be an optional add-on treatment for HD population with poor control of water; however, further well-designed controlled trials are warranted.

The facilitators and barriers to physical activity scale for people with mental illness in Taiwan: development and validation.

PURPOSE: The purposes of this study were to develop a new measure, the Facilitators and Barriers to Physical Activity Scale for People with Mental Illness (FBPAS-MI) and to validate the psychometrics. METHODS: This study included two phases. In Phase I, a literature review and five focus groups were conducted to develop an item bank. Then, expert consultation and cognitive interviews were used for content validity. In Phase II, 147 participants with severe mental illness were recruited from 10 community-based psychiatric rehabilitation centers in Taiwan to examine the psychometrics. Principal axis factoring method with direct oblique rotation was used to identify the underlying constructs of FBPAS-MI. Concurrent validity, internal consistency and test-retest reliability were examined. RESULTS: The results revealed five domains in the facilitator subscale (15 items) and two domains in the barrier subscale (11 items). Both subscales showed satisfactory internal consistency (all Cronbach's α >0.80); the concurrent validity and test-retest reliability were established. CONCLUSIONS AND IMPLICATIONS OF PRACTICE: This study confirmed that the FBPAS-MI is a valid and reliable scale to understand perceived facilitators and barriers to physical activity for severe mental illness. The FBPAS-MI can provide useful information in the development of individualized health promotion program for this population.Implications for RehabilitationThe Facilitators and Barriers to Physical Activity Scale for People with Mental Illness (i.e., FBPAS-MI) is a valid and reliable assessment to examine key factors affecting physical activity participation among people with severe mental illness.Psychiatric rehabilitation practitioners could use the FBPAS-MI to help develop and tailor individualized physical activity promotion programs based on identified facilitators and barriers to activity.

Intradialytic hypotension: Is intradialytic acupuncture a complementary option? A case report.

BACKGROUND: Intradialytic hypotension (IDH) is a common complication during hemodialysis (HD) and is positively associated with either poor quality of life or mortality. The present case report described the effect of intradialytic acupuncture (IA) in decreasing the occurrence of IDH. METHODS: A 70-year-old female with diabetic nephropathy had been receiving regular dialysis twice weekly since end-stage renal disease was diagnosed. She had several episodes of intradialytic systolic blood pressure (iSBP) drop accompanied with severe complications within one month. In the 10 dialysis sessions prior to IA intervention, the case patient experienced two episodes of nadir iSBP < 90 mmHg, seven episodes of iSBP drop ≥ 20 mmHg, among which two episodes occurred with symptoms; and three episodes of iSBP drop required nursing intervention. INTERVENTIONS: Dialysis sessions proceeded as usual with the patient receiving five sessions of 30-min IA as an add-on therapy starting from the second hour of dialysis. RESULTS: In the 10 sessions with IA administered alternately, she experienced one episode of nadir iSBP < 90 mmHg and three episodes of iSBP drop ≥ 20 mmHg, among which two episodes occurred with symptoms. Occurrence of IDH reduced and no IDH necessitating nursing intervention occurred during IA-HD sessions. CONCLUSIONS: The administration of IA showed potential effect in decreasing the occurrence of IDH.

Percutaneous transluminal angioplasty and stenting of post-irradiated stenosis of subclavian artery.

BACKGROUND/PURPOSE: The therapeutic efficacy of percutaneous transluminal angioplasty and stenting (PTAS) of post-irradiated stenosis of subclavian artery (PISSA) was not well clarified. This retrospective study was designed to evaluate the technical safety and outcome of the patients of severe symptomatic PISSA accepted PTAS. METHODS: Between 2000 and 2019, 16 cases with 17 lesions of symptomatic and medically refractory PISSA accepted PTAS were included. We evaluated their technical success, peri-procedural complications and diffusion-weight imaging (DWI) of brain magnetic resonance imaging (MRI), results of symptom relief, and long-term stent patency. RESULTS: The stenosis of the 17 stenotic lesions were 81.2 ± 11.1%. The most common symptom of the 16 patients was dizziness (14/16, 87.5%). All successfully accepted PTAS without neurological complication and had symptom relief after PTAS (17/17, 100%). Of the 12 patients accepted pre-procedural and early post-procedural MRI follow-up, 2 patients had an asymptomatic tiny acute embolic infarct in the territory of vertebrobasilar system. In a 51.9 ± 54.9 months follow-up, all patients had no severe restenosis and no recurrent vertebrobasilar ischemic symptoms. CONCLUSION: For patients with PISSA and medically refractory ischemic symptoms, PTAS can be an effective alternative management.

Metformin and the Risk of Anemia of Advanced Chronic Kidney Disease in Patients With Type 2 Diabetes Mellitus.

This retrospective cohort study determines whether metformin monotherapy or combination therapies can decrease anemia risk in the progress of advanced chronic kidney disease for patients with type 2 diabetes mellitus. The data set was obtained from the National Health Insurance Research Database, containing 1 million randomly selected beneficiaries. After matching, 9303 pairs (1:1) of metformin users and nonusers were acquired. Every patient was individually recorded from 1997 to 2012 to identify anemia incidence (hemoglobin <9 gm/dL). Cox regression models were used to compute hazard ratios and 95% confidence intervals (CIs). There were 305 (0.7%) and 76 (0.8%) erythropoietin-stimulating agent cases in the metformin and non-metformin cohorts over a mean follow-up period of 6.8 and 5.6 years. After matching, the use of metformin decreased the risk of usage of erythropoietin-stimulating agents with an adjusted hazard ratio of 0.76 (95%CI, 0.45-1.29) for dosage of <357 g to 0.30 (95%CI, 0.17-0.56) for >1368 g. The combination of metformin and dipeptidyl peptidase-4 inhibitors decreased with a hazard ratio of 0.42 (95%CI, 0.18-0.99), compared to metformin alone. Metformin combined with dipeptidyl peptidase-4 inhibitors is superior to metformin monotherapy or non-metformin antidiabetic therapies for reducing the risk of anemia in the progress of advanced chronic kidney disease among patients with type 2 diabetes.
