The SUBMAX and MAX had more SC at the nuclei level than CON. The SC nuclei were statistically larger in the SUBMAX and MAX. The number of microtubules and neurofilaments was statistically higher in the SUBMAX and MAX. Total training load and total load per climb were not different between groups. The SUBMAX and MAX statistically increased maximum carried load (ML). In conclusion, the different LRT protocols induced similar morphological responses in radial and sciatic nerves, probably due to load progression and equal total load volume.Different neural contributions to motor learning might be involved when different error sizes of perturbation are introduced. Although the corticospinal drive contributes to abrupt gait adaptation processes, no studies have investigated whether cortical involvement during gait differs between perturbations applied abruptly and gradually. This study aimed to investigate the differences in oscillatory common neural drives to ankle muscles during gait between abrupt and gradual adaptations, using coherence analyses of paired surface electromyographic (EMG) recordings. Sixteen healthy young adults performed the treadmill gait with perturbation resisting forward movement of the swing leg for 10 min under two conditions abrupt (a large perturbation from the beginning of the adaptation period) and gradual (a series of small perturbations that gradually increased). Swing phase duration and step length showed significantly greater asymmetry in the abrupt condition than in the gradual condition in the early adaptation period (p  less then  0.01), despite no significant differences in gait symmetries between the two conditions in the early post-adaptation period. EMG-EMG coherence calculated from the tibialis anterior muscle in the beta band (15-35 Hz) on the perturbed side was significantly higher in the early adaptation period in the abrupt condition (p  less then  0.05), but not in the gradual condition. There were significant relationships between changes in temporal gait symmetry and EMG-EMG coherence during the different adaptation periods between the two conditions (p  less then  0.05). The abrupt large perturbation seems to require a cortical involvement, whereas a gradual adaptation with small gait asymmetry requires no modulation of cortical involvement.Aim of this study is to categorize stones between 10 and 20 mm according to stone diameter or volume and compare mini percutaneous nephrolithotomy (mPNL) and retrograde intrarenal surgery (RIRS) outcomes. Files of 515 patients who underwent surgery for kidney stones with sizes 10-20 mm were reviewed. Patients were divided into RIRS or mPNL groups. An attempt was made to find the diameter and volume threshold values above which the success of the operation, complication rates and the number of auxiliary treatments deteriorated. Subgroup analysis was performed below and above the threshold value to reveal the optimal treatment methods. RIRS complications increased with volumes above 1064 mm3, number of auxiliary interventions increased with volumes above 1256 mm3, and success of the operation decreased with volumes above 1416 mm3. A subgroup analysis under and over 1064 mm3 was performed in RIRS group. Complication and auxiliary treatment rates were higher, operative success was lower in patients with a stone volume greater than 1064 mm3. In patients who underwent RIRS, for every 1000 mm3 increase in stone volume success of the operation decreased by 2.1 times, while the probability of auxiliary treatment increased by 2.8 times. In patients with kidney stones between 10 and 20 mm, it is more meaningful to use volume instead of diameter to determine the success rate. When mPNL is used instead of RIRS for volumes greater than 1064 mm3, the success rate will be higher, complication rate will be similar, and the need for auxiliary treatment will be lower.To evaluate the efficacy and safety of the use of Ningmitai capsule as an adjunctive stone expulsion therapy after RIRS. All patients were diagnosed with upper urinary tract calculi measuring 10-20 mm. The patients who successfully underwent RIRS were randomly assigned to the NMT capsule group (Ningmitai capsule, 1.52 g, three times daily) or the control group for 4 weeks based on the random number table method. The primary endpoints were the stone expulsion rate (SER) and stone-free rate (SFR). The average stone expulsion time (SET), average stone-free time (SFT) and complications were recorded. Between July 2, 2019, and December 17, 2020, 220 participants successfully underwent RIRS across 6 centers; 123 of them were randomized according to the exclusion criteria, and 102 (83%) were included in the primary analysis. The SERs on the 3rd, 7th, 14th and 28th days were significantly increased in the NMT capsule group compared with the control group (78.95% vs. 31.11%, 92.98% vs. 55.56%, 94.74% vs. 64.44%, 100% vs. 82.22%, respectively, p  0.05), and they improved significantly without sequelae. This study indicated that NMT capsules can significantly promote stone clearance and are more effective and safer for upper urinary calculi after RIRS.Trial registration Chinese Clinical Trial Registration No. ChiCTR1900024151.Date of registration June 28, 2019.This preliminary survey analysed mussel atresia incidences, estrogen-responsive and apoptotic-specific molecular end points, and aqueous and gonadal levels of selected estrogens from the East China coast. Estrogen levels were low (e.g.  less then  LOD-28.36 ng/L,  less then  LOD-3.88 ng/g wet weight of tissue for BPA) relative to worldwide freshwater environments, but high oocyte follicle atresia incidences (up to 26.6%) occurred at selected sites. Kenpaullone Expression of estrogen-responsive ER2 was significantly increased in males relative to females at sites with high atresia incidences in females. A second estrogen-responsive gene, V9, was significantly increased at two sites in April in females relative to males; the opposite was true for the remaining two sites. Apoptosis-specific genes (Bcl-2, fas) showed elevated expression in males relative to females at the site with the highest atresia incidence. These results provide coastal estrogen levels and the utility of several estrogen-specific molecular-level markers for marine mussels.

The Chronic Kidney Disease in children (CKiD) equation to estimate glomerular filtration rate eGFR = k × Ht / SCr (Ht = height in cm, SCr = serum creatinine in mg/dL), with fixed k = 0.413, has recently been optimized by introducing age/sex dependent k-values valid for young children up to young adults (the CKiD Under 25years (CKiDU25) equation). Although the CKiD equation was designed for children with chronic kidney disease (CKD), this equation found common use both clinically and in research, and also in children without CKD. This report aims to evaluate properties of CKiD and CKiDU25 in healthy children and adolescents.

Sex-specific metadata (height and creatinine) for healthy children were obtained from national growth curves and creatinine versus age curves. These data were used to calculate average CKiD and CKiDU25 values for each year of age and compare them against age-independent measured GFR of 107mL/min/1.73 m

.

The CKiD estimations show a steep decline with age (1.5mL/min/1.73 m

/year in females and 2.0mL/min/1.73 m

/year in males) over the entire age range (2-20years) and large differences between adolescent males and females. Due to the age/sex specific k-values, the CKiDU25 equation solves this age-decline artifact of the CKiD equation. However, CKiDU25 still shows a systematic higher estimation of about 10% in healthy males compared to females over the entire age range.

Although the CKiDU25 shows major improvements compared to the CKiD equation, as the unexpected age decline has been removed, a systematic difference is still observed between healthy males and females.

Oral nutritional supplements (ONS) are considered a cornerstone in the treatment plan of malnutrition in cancer patients. However, the prevalence of inappropriate prescription of ONS is high. In this study, we aim to investigate the effect of inappropriate oral nutritional supplementation (consisting of prescription of ONS without evident clinical indication, or the absence of ONS when at risk of malnutrition) on the quality of life of cancer outpatients.

A cross-sectional comparative study was conducted in 104 cancer outpatients, receiving ONS without prior malnutrition risk screening (n = 51), and patients not receiving ONS (n = 53). Nutritional risk screening was performed using the abridged patient-generated subjective global assessment (ab-PG-SGA). The quality of life was assessed using EORTC QLQ-C30 version 3.0 questionnaire. Multivariate analysis was conducted to determine the predictors of quality-of-life scales. Age (years), malnutrition (ab-PG-SGA scores), BMI (kg/m

), TSF (mm), MUAC (cm), ONS (yes, no) were entered into the linear regression analysis as predictors (backward stepwise linear regression analysis).

The prevalence of malnutrition risk (ab-PG-SGA ≥ 6) was 74%. The median score of the ab-PG-SGA for ONS receiving group was significantly higher (p = 0.045). Furthermore, univariate analysis showed that the scores of the global health status (QoL) and the role functioning (RF) scales were significantly lower for the ONS receiving group (p = 0.020 and p = 0.016, respectively). Multivariately, malnutrition, inappropriate ONS prescription, and triceps skin fold were found to be predictors of the RF scale, while malnutrition was the only predictor for the QoL.

The inappropriate ONS prescription does not improve nutritional status or quality of life of cancer outpatients.

Long-term survivors (LTSs) of allogeneic hematopoietic stem cell transplantation (allo-HCT) may experience oral long-term effects like chronic graft-versus-host disease (oral cGVHD). The aim of this study was to investigate oral cGVHD in patients treated at a young age (< 30years) more than 5years after allo-HCT without total body irradiation (TBI).

All 94 participants went through a semi-structured interview, and an oral examination. Diagnosis of oral cGVHD was based on the "National Institutes of Health (NIH) cGVHD diagnosis and staging consensus criteria" from 2014.

Mean age at transplantation was 17.5years (range 0.4-29.9years), and mean time since transplantation was 16.7years (range 6-26years). Oral cGVHD was diagnosed in 26 (28%) of 94 LTSs. Of which 20 (21.5%) showed lichen planus-like (LPL) changes, and additionally six (6.5%) also fulfilled the diagnostic criteria of oral cGVHD since they had one or more distinctive signs and symptoms of oral cGVHD combined with definite cGVHD in another organ. No LTSs reported oral cGVHD (NIH) grade 3. There was a significant association between cGVHD in the oral cavity and cGVHD in another organ (77% vs 29%, p < 0.001). Out of 72 LTSs, who answered the questions regarding taste disturbances, 16 (22%) reported dysgeusia. No LTSs developed secondary malignancies in the oral cavity during follow-up time.

Oral long-term effects, such as oral cGVHD, may persist for many years after allo-HCT without TBI-conditioning in patients treated at a young age.
