Unleashing the Power of Osmotic Energy: Metal Hydroxide-Organic Framework Membranes for Efficient Conversion.

Osmotic energy, as a renewable clean energy with huge energy density and stable yield, has received widespread attention over the past decades. Reverse electrodialysis (RED) based on ion-exchange membranes is an important method of obtaining osmotic energy from salinity gradients. The preparation of ion-exchange membranes with both high ion selectivity and ion permeability is in constant exploration. In this work, metal hydroxide-organic framework (MHOF) membranes are successfully prepared onto porous anodic aluminum oxide (AAO) membranes by a facile hydrothermal method to form Ni2(OH)2@AAO composite membranes, used for osmotic energy conversion. The surface is negatively charged with cation selectivity, and the asymmetric structure and extreme hydrophilicity enhance the ionic flux for effective capture of osmotic energy. The maximum output power density of 5.65 W m-2 at a 50-fold KCl concentration gradient is achieved, which exceeds the commercial benchmark of 5 W m-2. Meanwhile, the composite membrane can also show good performance in different electrolyte solutions and acid-base environments. This work provides a new avenue for the construction and application of MHOF membranes in efficient osmotic energy conversion.

Efficacy of robot-assisted gait training on lower extremity function in subacute stroke patients: a systematic review and meta-analysis.

BACKGROUND: Robot-Assisted Gait Training (RAGT) is a novel technology widely employed in the field of neurological rehabilitation for patients with subacute stroke. However, the effectiveness of RAGT compared to conventional gait training (CGT) in improving lower extremity function remains a topic of debate. This study aimed to investigate and compare the effects of RAGT and CGT on lower extremity movement in patients with subacute stroke. METHODS: Comprehensive search was conducted across multiple databases, including PubMed, Web of Science, Cochrane Library, EBSCO, Embase, Scopus, China National Knowledge Infrastructure, Wan Fang, SinoMed and Vip Journal Integration Platform. The database retrieval was performed up until July 9, 2024. Meta-analysis was conducted using RevMan 5.4 software. RESULTS: A total of 24 RCTs were included in the analysis. The results indicate that, compared with CGT, RAGT led to significant improvements in the Fugl-Meyer Assessment for Lower Extremity [MD = 2.10, 95%CI (0.62, 3.59), P = 0.005], Functional Ambulation Category[MD = 0.44, 95%CI (0.23, 0.65), P < 0.001], Berg Balance Scale [MD = 4.55, 95%CI (3.00, 6.11), P < 0.001], Timed Up and Go test [MD = -4.05, 95%CI (-5.12, -2.98), P < 0.001], and 6-Minute Walk Test [MD = 30.66, 95%CI (22.36, 38.97), P < 0.001] for patients with subacute stroke. However, it did not show a significant effect on the 10-Meter Walk Test [MD = 0.06, 95%CI (-0.01, 0.14), P = 0.08]. CONCLUSIONS: This study provides evidence that RAGT can enhance lower extremity function, balance function, walking ability, and endurance levels compared to CGT. However, the quality of evidence for improvements in gait speed remains low.

Multi-Pleated Alkalized Ti3 C2 Tx MXene-Based Sandwich-Like Structure Composite Nanofibers for High-Performance Sodium/Lithium Storage.

The volume expansion of CoFe2 O4 anode poses a significant challenge in the commercial application of lithium/sodium-ion batteries (LIBs/SIBs). However, metal-organic-frameworks (MOF) offer superior construction of heterostructures with refined interfacial interactions and lower ion diffusion barriers in Li/Na storage. In this study, the CoFe2 O4 @carbon nanofibers derived from MOF are produced through electrospinning, in situ growth followed by calcination, which are then confined within an MXene-confined MOF-derived porous CoFe2 O4 @carbon composite architecture under alkali treatment. The CoFe2 O4 nanofibers anchor on the alkalized MXene that is decorated with the NaOH solution to form a multi-pleated structure. The sandwich-like structure of the composite effectively alleviates the volume expansion and shortens the Li/Na-ion diffusion path, which displays high capacity and outstanding rate performance as anode materials for LIBs/SIBs. As a consequence, the obtained CoFe2 O4 @carbon@alkalized MXene composite anode shows satisfied rate performance at current density of 10 A g-1 for LIBs (318 mAh·g-1 ) and 5 A g-1 for SIBs (149 mAh g-1 ). The excellent cycling performance is further demonstrated at a high current density, where it maintains a discharge capacity of 807 mAh g-1 at 2 A g-1 after 400 cycles for LIBs and 130 mAh g-1 at 1 A g-1 even after 1000 cycles for SIBs.

The effects of exercise intervention on cognition and motor function in stroke survivors: a systematic review and meta-analysis.

BACKGROUND: Cognitive impairment was a common sequela among stroke survivors, and exercise intervention was a promising non-pharmacological treatment modality for it. PURPOSE: To explore the effects of exercise intervention programs on cognitive and motor function in patients with cognitive impairment after stroke. STUDY DESIGN: Systematic review and meta-analysis. METHODS: Seven online databases (PubMed, Embase, Cochrane Library, Web of Science, Scopus, PsycInfo, and SPORTDiscus) were searched from their inception to 10 February 2022. Randomised controlled trials (RCTs) comparing the effects of exercise with non-exercise rehabilitation, using the Montreal Cognitive Assessment, Addenbrooke's Cognitive Examination, Mini-Mental State Examination, Trial Making Test, Upper and Lower Extremity Fugl-Meyer Assessment, Berg Balance Scale, and Barthel Index, were selected. Calculations for each assessment were performed for the overall effect and the therapy of interest, taking into account the effect of stroke severity or stimulus parameters. RESULTS: Twelve RCTs involving 975 participants and investigating nine different types of exercise interventions were included. The results were not affected by participant characteristics or reactive balance outcomes. Our results emphasise the importance of lightweight and operable aerobic exercises. Exercise itself had a high potential to improve cognitive impairment and motor function after stroke. CONCLUSIONS: Exercise had significant positive effects on alleviating cognitive and motor impairments after stroke.

Effects of Baduanjin exercise on cognitive function and cancer-related symptoms in women with breast cancer receiving chemotherapy: a randomized controlled trial.

PURPOSE: Cognitive decline is one of the main side effects of breast cancer patients after relevant treatment, but there is a lack of clear measures for prevention and management without definite mechanism. Moreover, postoperative patients also have a need for limb rehabilitation. Whether the cognitive benefits of Baduanjin exercise can improve the overall well-being of breast cancer patients remains unknown. METHODS: This randomized controlled trial was conducted on 70 patients with breast cancer receiving chemotherapy who were randomly assigned and allocated to (1:1) a supervised Baduanjin intervention group (5 times/week, 30 min each time) or a control group for 3 months. The effects of Baduanjin exercise intervention were evaluated by outcome measures including subjective cognitive function, symptoms (fatigue, depression, and anxiety), and health-related quality of life at pre-intervention (T0), 4 weeks (T1), 8 weeks (T2), and 12 weeks (T3). The collected data were analyzed by using an intention-to-treat principle and linear mixed-effects modeling. RESULTS: Participants in the Baduanjin intervention group had a significantly greater improvement in terms of FACT-Cog (F = 14.511; p < 0.001), PCI (F = 15.789; p < 0.001), PCA (F = 6.261; p = 0.015), and FACT-B scores (F = 8.900; p = 0.004) compared with the control group over the time. The exercise-cognition relationship was significantly mediated through the reduction of fatigue (indirect effect: ß = 0.132; 95% CI 0.046 to 0.237) and the improvement of anxiety (indirect effect: ß = - 0.075; 95% CI - 0.165 to -0.004). CONCLUSIONS: This pilot study revealed the benefits of Baduanjin exercise for subjective cognition and health-related quality of life of Chinese breast cancer patients receiving chemotherapy and outlined the underlying mediating mechanism of exercise-cognition. The findings provided insights into the development of public health initiatives to promote brain health and improve quality of life among breast cancer patients. TRIAL REGISTRATION NUMBER: ChiCTR 2,000,033,152.

Paternal depressive symptoms during the early postpartum period and the associated factors following the implementation of the two-child policy in China.

AIM: To evaluate the prevalence of paternal depressive symptoms during the first three days of childbirth, as well as the associated factors, following the implementation of the two-child policy in China in 2015, which allows couples to have two children in the Chinese mainland. METHODS: A cross-sectional study was conducted among 318 fathers. Paternal depressive symptoms and self-efficacy of fathers were screened using the Edinburgh Postnatal Depression Scale and the General Self-Efficacy Scale, respectively. In addition, basic information of all parents and neonates was collected. Univariate analysis, binary logistic regression analysis, and principal component analysis (PCA) were used to identify the relationship between paternal depressive symptoms and its associated factors. RESULTS: Twenty-two percentage of fathers had depressive symptoms during the first three days of childbirth. Binary logistic regression analysis revealed that older fathers, those who slept for more than 8 h per night, or were dissatisfied with their living conditions were more susceptible to developing the symptoms. On the contrary, protective factors such as the educational level of fathers, planned pregnancy, prenatal guidance, having the second-born child, and higher self-efficacy were found to reduce the development of paternal depressive symptoms. PCA showed that the main components that influenced the paternal depressive symptoms were parental age and parity. CONCLUSIONS: The prevalence of paternal depressive symptoms during the postpartum period did not increase significantly after the implementation of the two-child policy in China. However, focusing on the associated factors is necessary in order to manage postpartum depression during the early postpartum period.

Incidence and predictors of left ventricular remodeling among elderly Asian women: a community-based cohort study.

BACKGROUND: Left ventricular (LV) remodeling is closely linked to the progression of heart failure. There are limited data on the epidemiology of new onset LV remodeling among elderly women, which requires further investigation. METHOD: We examined data from a community-based cohort of women aged > 65 years, who had received > 2 echocardiography scans from 2009 to 2014. Exclusion criteria for patients included prior echocardiographic evidence of left ventricular enlargement (LVE) or hypertrophy (LVH). LVE was defined as the index of left ventricular internal diameter at end-diastole to height, and LVH was defined as the left ventricular mass and thickness index which indicate hypertrophy. RESULTS: Of the 474 subjects (age 71.85 ± 6.47 years), 49 (10.3%) developed LVH, while 55 (11.6%) developed LVE during the mean follow-up period of 5 years. Independent predictors of LVH included: central blood pressure (CBP, per 10 mmHg) [HR 1.094, 95% CI 1.011-1.202], BMI˃25(kg/m 2)[HR 1.306, 95% CI 1.175-1.434], B-type natriuretic peptide (BNP) ≥ 100 (pg/mL) [HR 1.635, 95% CI 1.107-3.311] and brachial-ankle pulse wave velocity (baPWV) ≥16 m/s [HR 1.605, 95% CI 1.474-2.039]. Predictors of LVE were CBP (per 10 mmHg) [HR 1.121, 95% CI 1.027-1.238], BMI˃25(kg/m 2)[HR 1.302, 95% CI 1.173-1.444], Low-density lipoprotein cholesterol (LDL-C) [HR 1.193, 95%CI 1.013-1.405] and E/e' ratio [HR 1.077, 95% CI 1.017-1.140]. CONCLUSION: CBP and BMI were demonstrated to be independent and robust predictors of left ventricular remodeling among elderly women, including both LVE and LVH. BNP and baPWV were specifically related to the development of LVH, whereas LDL-C and E/e' ratio were related to LVE.

[Vestibular Dysfunction in Patients with Sudden Sensorineural Hearing Loss without Vertigo].

OBJECTIVE: To observe the vestibular dysfunction in sudden sensorineural hearing loss (SSHL) patients without vertigo. METHODS: Forty-two cases of unilateral SSHL without vertigo were enrolled in the study from May 2012 to May 2014. All patients underwent air conducted sound elicited oVEMP and cVEMP respectively. Some of them also received caloric test. Sixty-two SSHL patients with vertigo and twenty-five age-and gender-matched normal subjects were recruited as controls to analyze the vestibular dysfunction in SSHL patients without. vertigo. RESULTS: Abnormal oVEMP was observed in 54. 8% affected ears without vertigo (23/42), 64. 5% ears with vertigo (40/62), and 26. 0% normal ears (13/50). Abnormal cVEMP was observed in 52. 4% affected ears without vertigo (22/42), 48. 4% ears with vertigo (30/62), and 14. 0% normal ears (7/50). Caloric test was operated in 21 SSHL patients without vertigo and 29 patients with vertigo. Abnormal caloric test was observed in 52.4% (11/21) SSHL patients without vertigo and 75. 9% (22/29) SSHL patients with vertigo respectively. Statistical significance was found in oVEMP and cVEMP rates between SSHL without vertigo and normal group (P<0. 01). However, no significant statistical difference was found in oVEMP, cVEMP rates and caloric test between SSHL without vertigo and SSHL with vertigo group (P>0. 05). CONCLUSION: Vestibular function could be damaged in SSHL patients without vertigo. The abnormal rates of oVEMP, cVEMP and caloric test in SSHL patients without vertigo were similar to that of SSHL patients with vertigo. The appearance of vertigo might be irrelevant to the range and extent of vestibular dysfunction.

RESULTS: Totally, 328 publications were included. The number of annual publications has been rising rapidly in recent years. Beijing University of Chinese Medicine and Shanghai University of Sport are two of the best universities for Tai Chi treatment in osteoporosis. This area of research is dominated by Zhou, Y; Yu, DH; Pence, BC and Qin,L. Core authors and core institutions having a relatively low level of collaboration indicates that there may be limited interaction and cooperation between these key players in the field. China had the highest volume of publications, followed by the United States. Furthermore, the majority of the study subjects and influence mechanism are the focus of current research in this field. CONCLUSION: Tai Chi in osteoporosis research field is in a stage of stable development. Universities and higher education institutions are the leading institutions in this field. China and the United States emerging as high productivity nations. The study of Tai Chi in osteoporosis not only focuses on the applicable population, effects and intervention methods, but also gradually shifts to the mechanism study such as "secretion of beneficial factors", "physical exercise load" and "oxidative stress status".

Flexible Self-Supporting MOF-Based Bean Pod Cube Hollow Nanofibers for Ultralong Cycling and High Rate Na Storage.

Sodium-ion batteries (SIBs) have garnered significant attention due to their potential as an emerging energy storage solution. Tin sulfide (SnS) has emerged as a promising anode material for SIBs due to its impressive theoretical specific capacity of 1022 mA h g-1 and excellent electrical conductivity. However, its practical application has been hindered by issues such as large volume expansion, which adversely affects cycling stability and rate performance during the charge/discharge processes. In this study, a novel approach to address these issues by synthesizing the bean pod cube hollow metal-organic framework (MOF)-SnSx/NC@N-doped carbon nanofibers through a process involving electrospinning, PDA coating, and calcination. The Sn-MOF serves as a self-sacrificing template, facilitating the simultaneous dissociation of MOF and polymerization of dopamine, leading to the creation of hollow intermediates that retain tin components. Subsequent sulfidation results in the integration of the hollow MOF-SnSx/NC nanoparticles within 3D nitrogen-doped carbon nanofibers, forming the distinctive bean pod cube composite structure. This unique configuration effectively shortens the diffusion path and mitigates volume expansion for sodium ions, ultimately yielding an exceptional high rate performance of 130 mA h g-1 (10 A g-1) and an ultralong cycling performance of 328 mA h g-1 even after 3500 cycles (2 A g-1) as the anode for SIBs.

Geometrical and volume changes of the membranous vestibular labyrinth in guinea pigs with endolymphatic hydrops.

OBJECTIVE: To evaluate geometrical and volume changes of membranous vestibular labyrinths in guinea pigs after endolymphatic hydrops (EH). METHODS: The membranous labyrinths of normal guinea pigs and of those with EH for 4 and 8 weeks were reconstructed after being scanned using micro-computed tomography subseqent to being stained in osmium tetroxide (OsO4). The diameters and volumes of the semicircular ducts, ampullae, utricles and saccules were measured based on the three-dimensional models. RESULTS: The diameters of the ampullae and utricles of EH guinea pigs were greater than those of the normal guinea pigs, while there were no significant differences in the diameters of the semicircular ducts among all groups. The volumes of ampullae, utricles and saccules of the EH groups were greater than those of the control group, but there were no changes in volumes of semicircular ducts after EH. CONCLUSION: The dilations of the membranous vestibular labyrinth in guinea pigs with EH mainly occur at the ampullae, utricles and saccules.

Mediating effect of circadian rhythm between work stress and sleep quality in Chinese shift-working nurses: A cross-sectional survey.

AIM: This study examined the mediating effect of circadian rhythm amplitude (LV) and stability (FR) between work stress and sleep quality among Chinese shift-working nurses (SWNs). DESIGN: A cross-sectional study. METHODS: Three-hundred and seventy-nine nurses working in shifts were investigated by convenient sampling from six hospitals in Shanghai, China. The mediating effect was analysed using the structural equation model with bootstrapping procedures. RESULTS: Work stress could directly affect shift nurses' sleep quality and indirectly affect sleep quality through circadian rhythm amplitude and stability. The total indirect effects of work stress on sleep quality accounted for 36.7% of the total effect. The study revealed that poor sleep quality is very common among SWNs, which deserves attention. The mediating effect of the circadian rhythm provides new insights to improve sleep quality, not only by lightening the work stress but also by improving circadian rhythm in SWNs.

The Effect of Exercise on Weight and Body Composition of Breast Cancer Patients Undergoing Chemotherapy: A Systematic Review.

BACKGROUND: Chemotherapy is a primary adjuvant treatment strategy for breast cancer patients, accompanied by weight gain and negative changes in body composition. However, it is unknown whether exercise is effective in preventing said weight gain and mitigating body composition changes of breast cancer patients undergoing treatment. OBJECTIVES: The current study used meta-analysis with trial sequential analysis to determine exercise effect on weight and body composition of breast cancer patients undergoing chemotherapy. METHODS: Cochrane Library, PubMed, EMBASE, EBSCO, Scopus, and SinoMed were searched (from the database start date up to August 16, 2021) for randomized controlled studies evaluating the effect of exercise on weight or body composition among breast cancer patients during chemotherapy. RevMan software and TSA Software were used to assess the risk of bias and analyze study results. RESULTS: In total, 13 studies comprising 1828 participants were included. Meta-analysis showed that exercise could lead to lower weight, body mass index (BMI), and percentage of body fat during chemotherapy for breast cancer patients, and muscular strength showed significant improvement. Trial sequential analysis showed that evidence of muscular strength was sufficient, but BMI evidence requires further confirmation. CONCLUSION: This meta-analysis found significant differences in body weight, BMI, percentage of body fat, and muscular strength between exercise intervention groups and control groups. IMPLICATIONS FOR PRACTICE: Exercise during chemotherapy is beneficial in preventing weight gain and negative changes in body composition. Medical practitioners should encourage patients to start exercising during chemotherapy. However, further studies are required because insufficient sample sizes meant that outcomes of body composition remain unconfirmed.

The Efficacy of Reminiscence Therapy in Cancer-Related Symptom Management: A Systematic Review and Meta-Analysis.

BACKGROUND: At present, simple reminiscence has been widely used in the field of neurocognitive disorders, life review/life review therapy has been widely used in the field of cancer, and both simple reminiscence and life review/life review therapy are suitable for psychological disorders such as depression and anxiety. However, the efficacy of reminiscence in treating cancer-related symptom has not been fully assessed. OBJECTIVES: To evaluate the effect of reminiscence therapy (RT) on relieving cancer-related symptoms such as anxiety and depression in cancer survivals. METHODS: China National Knowledge Infrastructure (CNKI), VIP database, Wanfang Data Knowledge Service Platform, China Biomedical Database, PubMed, Cochrane Library, Embase, EBSCO, Scopus, and Ovid databases were searched. To collect clinical randomized controlled trials (RCT) on RT and cancer-related studies published from the establishment of the database to October 05, 2021. Two researchers independently evaluated the articles that met the inclusion criteria, meta-analysis was performed using RevMan5.4 software. RESULTS: A total of 20 RCTs published in 2010 to 2021 were included, with a total of 1853 cancer patients. Meta-analysis results showed that the anxiety scale (HADS-A and HAMA and SAS) and depression scale (HADS-D and HAMD and SDS) scores of the RT group were significantly lower than those of the control group (HADS-A: P = .0002; HAMA: P < .00001; SAS: P = .0010; HADS-D: P = .01; HAMD: P < .00001; SDS: P = .0001). Meta-analysis results showed that RT can improve overall quality of life of cancer patients of RT group to a certain extent hope (P < .00001). Meta-analysis results showed that the scores on the hope and dignity were significantly increased, and the difference were statistically significant (P < .001). CONCLUSION: This review indicates that RT has significant efficacy on cancer-related symptoms such as anxiety and depression. RT for cancer survivals can effectively improve quality of life, self-hope, and self-esteem. The findings of this meta-analysis can provide direction for future symptom management research.

In Situ Growth of MOF-303 Membranes onto Porous Anodic Aluminum Oxide Substrates for Harvesting Salinity-Gradient Energy.

As an emerging metal-organic framework (MOF) material in recent years, the MOF-303 membrane has shown great potential applications in seawater desalination, dehydration, and atmospheric water harvesting. Herein, we report on a dense and uniform MOF-303 membrane fabricated by a facile in situ hydrothermal synthesis approach in the presence of an anodized aluminum oxide (AAO) channel membrane acting as the only Al source and substrate. Interestingly, the MOF-303 isomer can be obtained due to an insufficient amount of organic ligand caused by the less hydrophilic and larger pore size of the AAO substrate. The MOF-based composite membranes possessed surface-charge-governed ionic transport behavior. Moreover, the MOF-303/AAO membrane yielded an output power density of 1.87 W/m2 under a 50-fold KCl concentration gradient. Under a 50-fold gradient of artificial seawater and river water, a maximum power density of 1.46 W/m2 can be obtained. After 30 days of stability testing, the composite membrane still maintained the power output, and the power density was higher than 1.20 W/m2. This work provides a facile and effective strategy for constructing Al-based MOF composite membranes and boosts their applications in harvesting salinity-gradient energy.

Effects of repetitive transcranial magnetic stimulation on post-stroke patients with cognitive impairment: A systematic review and meta-analysis.

BACKGROUND: Post-stroke cognitive impairment (PSCI) is one of the common symptoms in stroke survivors, by which their quality of life and rehabilitation progress are severely limited. Repetitive transcranial magnetic stimulation (rTMS) has been proven to regulate cognition in a non-invasive way. However, the inconsistency in its effectiveness on PSCI reported in previous studies cannot be ruled out. A critical and comprehensive systematic review of rTMS on PSCI patients is necessary. METHODS: Trials published before the end of February 2022 on rTMS and PSCI were systematically retrieved from PubMed, Cochrane Library, EBSCO, Embase and SCOPUS. High-quality literature was selected following the inclusion and exclusion criteria, with their references being screened. Meta-analysis of data was carried out using RevMan 5.4 software. RESULTS: Ten trials involving 347 participants were included in the current review. Global cognition as measured by MMSE or MoCA (SMD=0.54; 95% CI=0.31, 0.76; P < 0.00001; I2 = 38%) and modified Barthel index (MD=9.00; 95% CI=2.93, 15.06; P = 0.004; I2 = 0%) were significantly improved by rTMS compared to sham stimulation in PSCI patients. Performance of the digit symbol test, rivermead behavioral memory test and attention in PSCI patients were also significantly improved. Subgroup analyses showed that significant differences were found in both MoCA and MMSE among PSCI patients by rTMS. MoCA was significantly improved by high frequency rTMS, while both MoCA and MMSE were significantly improved targeting on left dorsolateral prefrontal cortex. CONCLUSION: rTMS provides a non-invasive and effective technique for the treatment of post-stroke patients with cognitive impairment.

The effects of the mirror therapy on shoulder function in patients with breast cancer following surgery: a randomized controlled trial.

PURPOSE: Shoulder dysfunction is one of the most bothersome questions for breast cancer survivors. Studies show that mirror therapy can improve shoulder function in patients with a limited shoulder range of motion and shoulder pain. Here, this article reports the results of a randomized controlled trial investigating the effects of the mirror therapy on shoulder function in patients with breast cancer following surgical treatments. METHODS: Totally, 79 participants were divided to two groups receiving active range-of-motion upper limb exercise based on the mirror therapy or active range-of-motion upper limb exercise respectively for 8 weeks. Shoulder range of motion, Constant-Murley Score, Disabilities of Arm, Shoulder, and Hand Questionnaire, Tampa Scale of Kinesiophobia, Visual analog scale, and grip strength were measured at baseline (T0), 2 weeks (T1), 4 weeks (T2), and 8 weeks (T3). The effects of the intervention on shoulder function were analyzed in generalized estimation equation, from group, time, and the interactions between group and time based on the data from participants who completed at least one post-baseline observation RESULTS: At least one post-baseline observation was performed by 69 participants (n=34 mirror group, n=35 control group). 28(82.35%) participants in the mirror group adhered to the exercise compared to 30(85.71%) in the control group. Generalized estimation equation model showed group had main effects on forward flexion (Waldχ²=6.476, P=0.011), with the Cohen's d=0.54. The effects of the group on abduction, Constant-Murley Score, and Disabilities of Arm, Shoulder, and Hand Questionnaire were significant when fix the effects of the time. At 8 weeks, participants in the mirror group showed an improvement in abduction compared to the control group (P=0.005), the Cohen's d was 0.70. At 8 weeks, participants in the mirror group had a higher Constant-Murley Score than control group (P=0.009), with Cohen's effect size value of d=0.64. The mirror group showed a greater improvement on the Disability of Arm, Shoulder, and Hand Questionnaire than control group at 2 weeks, 4 weeks, and 8 weeks (P≤0.032), but with a weak effect size value of all (r≤0.32). Group had main effects on Tampa Scale of Kinesiophobia (Waldχ²=6.631, P=0.010), with the Cohen's effect size value of d=0.56. CONCLUSIONS: Mirror therapy improved shoulder flexion, abduction, shoulder function in daily life, and arm function and symptom of the affected shoulder in patients with breast cancer following surgical treatment, while decreasing fear of movement/(re)injury. Mirror configuration needs to be improved in further research to increase its feasibility. IMPLICATIONS FOR CANCER SURVIVORS: Breast cancer survivors can try mirror therapy as a practical and effective method in shoulder rehabilitation for a promotion on effects.

Heterostructure Fe2O3 nanorods@imine-based covalent organic framework for long cycling and high-rate lithium storage.

Fe2O3 as an anode for lithium-ion batteries has attracted intense attention because of its high theoretical capacity, natural abundance, and good safety. However, the inferior cycling stability, low-rate performance, and limited composite varieties hinder the application of Fe2O3-based materials. In this work, an Fe2O3@COF-LZU1 (FO@LZU1) anode was prepared via an imine-based covalent organic framework (COF-LZU1) covering on the exterior surface of Fe2O3 after rational optimization. With its unique heterostructure, the COF-LZU1 layer not only effectively alleviated the volume expansion during cycling but also improved the charge-transfer capability because of the π-conjugated system. Moreover, the organic functional group (CN, benzene ring) for COF-LZU1 provided more redox-active sites for Li+ storage. Under the contributions of both Fe2O3 nanorods and COF-LZU1, the FO@LZU150% exhibited an ultrahigh initial capacity and long-term cycling performance with initial discharge capacities of 2143 and 2171 mA h g-1 after 300 cycles under 0.1 A g-1, and rate performance of 1310 and 501 mA h g-1 at 0.3 and 3 A g-1, respectively. In addition, a high retention capacity of 1185 mA h g-1 was achieved at 1 A g-1 after 500 cycles. Furthermore, a full-cell with the FO@LZU150% anode and LiCoO2 cathode exhibited superior cycling and rate performance, which still maintained a reversible capacity of 260 mA h g-1 after 200 cycles even at a current density of 1 A g-1. The proposed strategy offers a new perspective for exploring the high-rate capability and designability of Fe2O3-based electrode materials.

Adaptive Auricular Point Acupressure for Sleep Disturbance in Women with Breast Cancer: A Randomized Controlled Trial.

Objectives: The study aimed to evaluate the preliminary effect and efficacy of auricular point acupressure (APA) on the quality of sleep in women with breast cancer who were undergoing chemotherapy. Sample & Setting. We conducted a randomized controlled trial on 68 patients with breast cancer who reported poor sleep quality based on the Pittsburgh Sleep Quality Index (PSQI) scores (>7). Methods & Variables. Participants were randomly assigned to an APA treatment group or a control group. Patients in the APA group had magnetic pellets attached to selected auricular points and were instructed to apply pressure to these points 4×/day for three consecutive weeks. We objectively measured sleep quality using the Actiwatch Spectrum and the PSQI at the baseline and postintervention. Statistical analyses of changes in sleep data were performed using the t-test, a rank-sum test, and analyses of covariance. Results: In patients treated with APA, the PSQI total score and sleep onset latency had significantly decreased, while the total sleep time and sleep efficiency had significantly increased. Although the total PSQI score differed between groups at the baseline, ANCOVA results showed that the APA group had a significantly lower total PSQI score. Conclusion: APA could be an inexpensive and effective approach to improving sleep quality and reducing sleep disturbance in patients with breast cancer. Further research needs a larger sample size to verify our findings.
