The relationship between the baseline geriatric nutritional risk index (GNRI) and neurological function at the convalescence stage in patients with stroke: a cross-sectional study.

BACKGROUND: Malnutrition is a common complication after stroke and may worsen neurological outcomes for patients. There are still no uniform tools for screening nutritional status for the patients with stroke. We aimed to explore the relationship between the baseline geriatric nutritional risk index (GNRI) and neurological function at the convalescence stage for patients with stroke and assessed the predictive value of the GNRI for adverse neurological outcomes. METHODS: A total of 311 patients with stroke were enrolled retrospectively. Basic information and laboratory results on admission since onset of stroke were collected. The GNRI on admission was calculated and neurological outcomes evaluated by the Barthel index at 1 month after the onset of stroke. Statistical analyses, including correlation coefficient tests, multivariate regression analyses, and receiver operating characteristic (ROC) analyses, were applied in this study. RESULTS: Compared with the good outcome group, the poor outcome group showed a significantly lower GNRI on admission (P < 0.05). GNRI was associated with Barthel index (r = 0.702, P < 0.01). The GNRI was independently correlated with the Barthel index (Standardization ß = 0.721, P < 0.01) and poor outcome 0.885 (95% CIs, 0.855-0.917, P < 0.01) after adjusting for covariates. Compared with no nutritional risk grades (Q4), the OR of GNRI to poor neurological outcome increased across increasing nutritional risk grades of GNRI (OR = 2.803, 95% CIs = 1.330-5.909 in Q3, 7.992, 95% CIs = 3.294-19.387 in Q2 and 14.011, 95% CIs = 3.972-49.426 in Q1, respectively, P for trend < 0.001). The area under ROC curves (AUC) of the GNRI was 0.804, which was larger than that of the NIHSS, BMI, or Albumin (P < 0.01), with an optimal cut-off value of 97.69, sensitivity of 69.51% and specificity of 77.27%. Combined GNRI with NIHSS gained the largest AUC among all the variables (all P < 0.05), with an AUC of 0.855, sensitivity of 84.75 and specificity of 72.73%. CONCLUSIONS: For patients with stroke, higher nutritional risk grades at baseline indicated worse neurological function at the convalescence stage. Compared with NIHSS, BMI, and Albumin, GNRI was a competitive indicator for the risk of poor neurological outcome. The predictive property of GNRI for adverse neurological outcomes might be more powerful when combined with NIHSS.

Botulinum toxin A injection using ultrasound combined with balloon guidance for the treatment of cricopharyngeal dysphagia: analysis of 21 cases.

BACKGROUND: As an upper oesophageal sphincter (UES) dysfunction disorder, cricopharyngeal achalasia (CPA) is a common cause of dysphagia and is associated with an increased risk of pulmonary complications. The aim of this study was to investigate the effectiveness and safety of BTX-A injection using ultrasound combined with balloon guidance for the treatment of CPA caused by stroke. METHODS: A total of 21 patients diagnosed with CPA were treated with BTX-A injection into the cricopharyngeal muscle using ultrasound combined with balloon guidance. Primary outcome measures, including the functional oral intake scale (FOIS), videofluoroscopic dysphagia scale (VDS) and penetration aspiration scale (PAS), which are quantitative measures for a video fluoroscopic swallowing study (VFSS), and scores of the self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were assessed from baseline to 12 weeks after treatment. Repeated measures analysis of variance was used to compare the scores between time points. RESULTS: BTX-A injection led to improved dysphagia symptoms and scores in 19 patients (90.48%). Among them, 5 cases were cured (23.81%), 11 cases showed significant improvement (52.38%), and 3 cases showed improvement (14.29%). Two cases were absolutely ineffective (9.52%). Compared with the scores prior to treatment, the scores on the FOIS, VDS, PAS, SAS and SDS significantly improved beginning at 3 days (p < .05) and lasting for at least 12 weeks after injection. CONCLUSIONS: Ultrasound with balloon-guided BTX-A injection is probably a relatively safe, easy, and effective technique for the treatment of CPA caused by stroke, with better visualization of the injection procedure. A well-designed controlled trial with a larger sample size is needed for more convincing conclusions.

Efficacy of Roxadustat on anemia and residual renal function in patients new to peritoneal dialysis.

BACKGROUND: Both early correction of anemia and preserving residual renal function (RRF) are reported to improve patient survival. The aim of this study was to explore the efficacy and safety of Roxadustat for treatment of renal anemia in patients new to peritoneal dialysis (PD) and to assess its impact on RRF. METHODS: A retrospective analysis was performed on 60 initial peritoneal dialysis (PD) patients with renal anemia. Twenty-eight cases were treated with Roxadustat (Roxadustat group) and 32 with recombinant human erythropoietin (control group). Clinical characteristics, hemoglobin (Hb), C-reactive protein, blood lipids, iron metabolism, dialysis adequacy and RRF of the two groups were evaluated and adverse events were recorded. All patients were followed up for at least 40 weeks. RESULTS: After 40 weeks of treatment, mean Hb levels were significantly higher from baseline values in both groups, the mean Hb change in Roxadustat group was higher than control group (3.46 ± 1.59 g/dL vs. 2.28 ± 2.27 g/dL, p < 0.05). At 40 weeks, 92.9% patients met the target level of Hb in Roxadustat group and 84.4% in control group. Total iron binding was higher and ferritin was lower in Roxadustat group from baseline values and Roxadustat-induced Hb increases were independent of baseline C-reactive protein levels and history of rhuEPO administration. RRF decreased over time in both groups, the mean RRF change was lower in Roxadustat group than control group (1.15 ± 1.66 mL/min/1.73 m2 vs. 2.31 ± 1.46 mL/min/1.73 m2, p < 0.01). Compared with control group, patients in Roxadustat group had higher levels of total iron binding, 24 h urine volume, total weekly Ccr, and lower systolic pressure, ferritin, C-reactive protein, total cholesterol, LDL. No serious adverse reactions occurred in either group. CONCLUSION: In patients new to PD, Roxadustat effectively and safely improved renal anemia and delay the decline of RRF.

The Effects of Adding Di-Tan Decoction (DTD) and/or Electroacupuncture (EA) to Standard Swallowing Rehabilitation Training (SRT) for Improving Poststroke Dysphagia (PSD): A Pilot, Single-Centred, Randomized Trial.

Objectives: To evaluate the effect of adding Di-tan decoction (DTD) and/or electroacupuncture (EA) to standard swallowing rehabilitation training (SRT) on improving PSD. Methods: In total, 80 PSD patients were enrolled and randomly assigned to the DTD, EA, DTD + EA or control group at a 1 : 1 : 1 : 1 ratio. All patients received basic treatment and standard SRT. The DTD group received DTD orally, the EA group received EA, the DTD + EA group received both DTD and EA simultaneously, and the control group received only basic treatment and standard SRT. The interventions lasted for 4 weeks. The outcome measurements included the Standardized Swallowing Assessment (SSA) and Swallowing-Quality of Life (SWAL-QOL), performed and scored from baseline to 2, 4, and 6 weeks after intervention, and the Videofluoroscopic Dysphagia Scale (VDS), scored at baseline and 4 weeks after intervention. Scores were compared over time by repeated-measures analysis of variance (ANOVA) among all groups. Interactions between interventions were explored using factorial design analysis. Results: (1) The effective rates (ERs) for PSD treatment were higher in the DTD, EA and DTD + EA groups than in the control group (all P < 0.05). The ER was higher in the DTD + EA group than in the DTD or EA group (both P < 0.05). (2) There were significant group effects, time effects and interactions for the SSA and SWAL-QOL scores (all P < 0.05). All groups showed decreasing trends in SSA scores and increasing trends in SWAL-QOL scores over time from baseline to 6 weeks after intervention (all P < 0.01). (3) Factorial design analysis for ΔVDS showed that there was a significant main effect for DTD intervention (F = 11.877, P < 0.01) and for EA intervention (F = 29.357, P < 0.01). However, there was no significant interaction effect between DTD and EA (F = 0.133, P = 0.717). Multiple comparisons showed that the DTD, EA and DTD + EA groups all had higher ΔVDS values than the control group (P < 0.05). The DTD + EA group had a higher ΔVDS than the DTD or EA group (both P < 0.05). (4) Most adverse reactions were mild and transient. Conclusions: Adding DTD or EA to SRT can better improve PSD than applying SRT alone. Adding DTD and EA simultaneously can accelerate and amplify the recovery of swallowing function versus DTD or EA alone, and both are effective and safe treatments, alone or jointly, for PSD and are a powerful supplement to routine treatments.

Superhydrophobic-superoleophilic biochar-based foam for high-efficiency and repeatable oil-water separation.

Leakage accidents occurring during oil production and transportation are currently one of the most serious environmental problems worldwide. Developing efficient and environmentally friendly oil-water separation methods is the key to solve this problem. In this work, a facile method to fabricate a high-performance oil absorbent through the loading of ball-milled biochar (BMBC) and octadecylamine on the skeleton of melamine foam (MF) is reported. The resulting ball-milled biochar-based MF (BMBC@MF) displayed a complex three-dimensional porous structure. The BM biochar on the surface of BMBC@MF forms nano/µm-scale folds, which reduced the surface energy of BMBC@MF after grafted octadecylamine. These structures resulted in the conversion of the hydrophilic surface of MF to hydrophobic surface. These characteristics made the modified foam an excellent oil absorbent with a high oil absorption capacity (43-155 times its own weight) and extraordinary recyclability. Furthermore, the BMBC@MF could maintain high hydrophobicity and adsorption stability in a wide pH range (from 1 to 11). More importantly, BM biochar is a cheap and readily available material to make BMBC@MF possible for large-scale production. Therefore, this work provides an effective way for low-cost, environmentally friendly, and large-scale production of superhydrophobic adsorbents for oil-water separation.

Membranous nephropathy associated with malignant pleural mesothelioma in an adult patient: A case report.

A 23-year-old man presented to our hospital with membranous nephropathy and received a detailed examination, including pleural biopsy, due to a feeling of chest oppression. The result of the pleural biopsy was malignant pleural mesothelioma. However, the patient did not have a history of asbestos or tobacco exposure. A review of the English literature identified only 7 reported cases of concomitant malignant mesothelioma and nephrotic syndrome. Furthermore, among the 7 cases reviewed, 6 had a history of asbestos exposure, 1 had a history of prolonged tobacco exposure and in only 1 case the renal pathology results revealed the presence of membranous nephropathy.
