Objectives The aim of this study was to evaluate the relationship between cognitive impairment and brain perfusion using arterial spin labelling (ASL) in end-stage renal disease (ESRD) patients undergoing PD. Methods ESRD patients undergoing PD were recruited. Laboratory screening, neuropsychological tests and ASL magnetic resonance imaging (MRI) were conducted prior to and after 6 months of PD. Age- and sex-matched normal subjects without ESRD served as the control group. Comparisons of regional CBF between ESRD patients before or after undergoing PD and normal controls were performed. Correlations between biochemical, neuropsychological and CBF data were also conducted to evaluate the relationships. Results ESRD patients showed poor performance in many of the neuropsychological tests; PD improved cognition in some domains. Pre-PD patients had higher mean CBF than post-PD patients and normal controls, but no significant difference was found between the normal controls and post-PD patients. Negative correlations were observed pre-PD (regional CBF in left hippocampus vs. perseverative responses, r = -0.662, p = 0.014), post-PD (mean CBF vs. haemoglobin level, r = -0.766, p = 0.002), and before and after PD (change in CBF in the left putamen vs. change in haematocrit percentage, r = -0.808, p = 0.001). Conclusion Before PD, ESRD patients had increased cerebral perfusion that was related to poorer executive function, especially in the left hippocampus. Post-PD patients performed better in some cognitive test domains than pre-PD patients. The degree of anaemia, i.e., haemoglobin level or haematocrit percentage, might predict cognitive impairment in PD patients. Key Points • In this study, ESRD patients before PD had cerebral hyperperfusion that was related to poorer executive function. • Post-PD patients performed better in some cognitive test domains than pre-PD patients did. • The degree of anaemia might predict cognitive impairment in PD patients.

Local corticosteroid injections are commonly used to improve the short-term symptomatic severity and the functional status of the hands affected by carpal tunnel syndrome. We conducted a systematic review and Bayesian network-meta-analysis to compare the clinical effectiveness of local corticosteroid injections using different injection approaches. Electronic literature in Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Web of Science, and other sources were searched to identify clinical studies comparing different injection approaches with each other or placebo for carpal tunnel syndrome. Two review authors conducted selection of studies, data extraction, and assessment of risk of bias independently. Random-effects models were used to conduct the pairwise meta-analysis and the Bayesian network meta-analysis. Overall, 10 studies with 633 patients were included in the systematic review. Among the injection approaches, local corticosteroid injections using the ultrasound-guided in-plane injection (Ulnar-I) approach was the best treatment strategy for clinical response (median OR versus placebo 128.30, 95 % CrI 9.76 to 2299.00), change in symptom severity scale (median MD versus placebo −1.16, 95 % CrI −1.95 to −0.38) , and change in functional status scale (median MD versus placebo −0.74, 95 % CrI −2.00 to 0.52) at short-term follow-up period in the network meta-analysis. Local corticosteroid injections using other injection approaches were better than placebo for clinical response (for the PI approach, median OR versus placebo 8.85, 95 % CrI 3.00 to 33.15; for the DI approach, median OR versus placebo 7.00, 95 % CrI 0.53 to 118.80) , change in symptom severity scale (for the Ulnar-O approach, median MD versus placebo −0.78, 95 % CrI −1.43 to −0.16; for the PI approach, median MD versus placebo −0.58, 95 % CrI −0.95 to −0.22), and change in functional status scale (for the Ulnar-O approach, median MD versus placebo −0.63, 95 % CrI −1.67 to 0.43; for the PI approach, median MD versus placebo −0.46, 95 % CrI −1.11 to 0.21) at short-term follow-up period. The quality of studies is good. According to our analyses, the ultrasound-guided in-plane injection (Ulnar-I) approach was the most effective treatment among the injection approaches for carpal tunnel syndrome.

Post-stroke spasticity is a common complication in patients with stroke and a key contributor to impaired hand function after stroke. The purpose of this study was to investigate the effects of kinesio taping on managing spasticity of upper extremity and motor performance in patients with subacute stroke. A randomized controlled pilot study. A hospital center. Participants with stroke within six months. Thirty-one participants were enrolled. Patients were randomly allocated into kinesio taping (KT) group or control group. In KT group, Kinesio Tape was applied as an add-on treatment over the dorsal side of the affected hand during the intervention. Both groups received regular rehabilitation 5 days a week for 3 weeks. The primary outcome was muscle spasticity measured by modified Ashworth Scale (MAS). Secondary outcomes were functional performances of affected limb measured by using Fugl-Meyer assessment for upper extremity (FMA-UE), Brunnstrom stage, and the Simple Test for Evaluating Hand Function (STEF). Measures were taken before intervention, right after intervention (the third week) and two weeks later (the fifth week). Within-group comparisons yielded significant differences in FMA-UE and Brunnstrom stages at the third and fifth week in the control group (P=0.003-0.019). In the KT group, significant differences were noted in FMA-UE, Brunnstrom stage, and MAS at the third and fifth week (P=0.001-0.035), and in the proximal part of FMA-UE between the third and fifth week (P=0.005). Between-group comparisons showed a significant difference in the distal part of FMA-UE at the fifth week (P=0.037). Kinesio taping could provide some benefits in reducing spasticity and in improving motor performance on the affected hand in patients with subacute stroke. Kinesio taping could be a choice for clinical practitioners to use for effectively managing post-stroke spasticity.
