Parkinson's disease (PD) is characterized by progressive neurological deterioration, typically accompanied by reductions in skeletal muscle force-generating capacity (FGC) and functional performance. Physical activity has the potential to counteract this debilitating outcome, however, it is elusive if high-intensity strength training included in conventional treatment may improve results. Therefore, we randomly assigned 22 PD patients (74 ± 9 yr) to conventional rehabilitation with or without maximal strength training (MST) performed as leg press and chest press at ~90% of one repetition maximum (1RM), five times per week for 4 wk. FGC, physical performance, and efferent neural drive assessed as evoked potentials (V-wave normalized to M-wave in m. soleus) were measured following training. Results revealed that only MST improved 1RM leg press (101 ± 23 to 118 ± 18 kg) and chest press (36 ± 15 to 41 ± 15 kg), plantar flexion maximal voluntary contraction (235 ± 125 to 293 ± 158 N·m), and rate of force developmeeural drive, maximal muscle strength, rate of force development, and functional performance in patients with Parkinson's disease (PD). In contrast, no differences were observed in these outcome variables in patients receiving conventional treatment consisting of recreational physical activity with low-to-medium intensity. Consequently, this study advocates that high-intensity strength training should be implemented in the clinical treatment of PD patients.Adults born preterm, regardless of whether they develop bronchopulmonary dysplasia, have underdeveloped respiratory and cardiopulmonary systems. The resulting impaired respiratory and cardiopulmonary systems are inadequate for the challenges imposed by aerobic exercise, which is exacerbated by the presence of bronchopulmonary dysplasia. Sunitinib in vitro Thus the respiratory and cardiopulmonary systems of these preterm individuals may be the most influential contributors to the significantly lower aerobic exercise capacity compared with their term born counterparts. The precise underlying cause(s) of the lower aerobic exercise capacity in adults born preterm is not entirely known but could be a number of interrelated parameters including mechanical ventilatory constraints, impaired pulmonary gas exchange efficiency, and excessive cardiopulmonary pressures. Likewise, additional aspects, such as impaired cardiovascular function and altered muscle bioenergetics, may play additional roles in limiting aerobic exercise capacity. Whether or not all or some of these aspects are present in adults born preterm and precisely how they may contribute to the lower aerobic exercise capacity are only beginning to be systematically explored. The purpose of this mini-review is to outline what is currently known about the respiratory and cardiopulmonary limitations during exercise in this population and to identify key areas where additional knowledge will help to advance this area. Additionally, where possible, we highlight the similarities and differences between obstructive lung disease resulting from preterm birth and chronic obstructive pulmonary disease (COPD) as the physiology and pathophysiology of these two forms of obstructive lung disease may not be identical.High-intensity interval training (HIIT) can improve vascular function, as assessed by brachial artery flow-mediated dilation (FMD). However, when separated by a period of detraining, the reproducibility of FMD responses to repeated periods of HIIT is unknown. The purpose of this study was to determine the group mean and intraindividual reproducibility of FMD responses to two 4-wk periods of HIIT, separated by 3 mo of detraining. Thirteen healthy, recreationally active men (21 ± 2 yr) completed the study. Each 4-wk HIIT period included 40 min of treadmill training four times/week. Each training session included four 7-min intervals 4 min at 90%-95% heart rate maximum (HRmax) and 3 min at 70%-75% HRmax. Vascular (FMD) and cardiorespiratory fitness (maximal oxygen consumption [V̇o2max]) assessments were conducted before and following each 4-wk training period. Training resulted in significant improvements in V̇o2max (P less then 0.001). Training also improved FMD (P less then 0.001), with no differences betwspite considerable between-subject variability in FMD adaptation, individual FMD changes with the first HIIT period predicted FMD changes in the second period. This indicates the existence of reproducible between-subject differences in susceptibility to FMD improvement with HIIT.
Young people (ages 12-25) experience the highest risk of developing mental disorders; however, their uptake of and engagement with treatment is low. The study explored sociodemographic predictors of attendance and discontinuation of mental health services in a large, population-based sample.

Data were from the minimum data set collected from young people (ages 12-25) who attended headspace, Australia's National Youth Mental Health Foundation, from 2013 to 2017 (N=80,502). Data on key demographic and clinical variables and practitioner ratings of need for ongoing care were analyzed. Cox regression was used to examine the association between sociodemographic factors and rates of discontinuation based on practitioner-rated need for ongoing treatment.

The mean±SD number of sessions attended during the first episode of care was 4.6±4.4 sessions (median=3). Session-by-session discontinuation rates ranged from 14% to 19% across 10 sessions. The proportion discontinuing treatment before session 11 was 71.2%. Analysis of a subgroup (N=40,039) showed that 24% of those who discontinued treatment later returned to the same headspace center for a second episode of care. Those who were most at risk of discontinuation were older (ages 18-25), male, heterosexual, Aboriginal or Torres Strait Islander, and living in a rural location.

Sociodemographic factors were found to be associated with treatment discontinuation, and some young people followed a pathway in and out of mental health treatment. Further exploration is needed to determine the appropriate length and type of care for specific sociodemographic groups and how best to tailor treatment accordingly.

In colorectal cancer (CRC) patients, guidelines only recommend measurement of preoperative carcinoembryonic antigen (CEA), although postoperative CEA may be more informative. However, the sensitivity of both preoperative and postoperative CEA in identifying relapse is limited. We studied whether CA19-9, YKL-40, C-reactive protein (CRP) and interleukin (IL)-6 add prognostic information combined with postoperative CEA.

This post-hoc analysis included 147 radically resected stage II (
 = 38), III (
 = 91) and IV (
 = 18) CRC patients treated with adjuvant 5-fluorouracil (5-FU)-based therapy in the phase III LIPSYT study (ISRCTN98405441). We collected postoperative blood samples a median of 48 days after surgery. We analysed relapses, sensitivity, positive predictive value (PPV) and disease-free (DFS) and overall survival (OS) by bootstrap, Kaplan-Meier and adjusted Cox-models in the elevated vs. normal biomarker groups.

Elevated postoperative CEA associated with impaired DFS (HR 7.23; CI
3.85-13.58), ination with CA19-9, YKL-40, CRP, or IL-6, or a normal CEA combined with an elevated YKL-40 or with an elevated CRP, may indicate patients at high risk of relapse.
Cochlear implantation (CI) has been successfully used to restore hearing in patients with severe to profound hearing loss. In addition to hearing loss, irradiated patients with nasopharyngeal carcinoma (NPC) also often have chronic otitis media and Eustachian tube (ET) dysfunction. These features may result in difficulties in CI. We conducted this study to review the management options for irradiated patients with NPC undergoing CI. Furthermore, we investigated the results of CI in irradiated patients with NPC with chronic otitis media and obstructive ET dysfunction, accordingly to different treatment strategies.

We retrospectively reviewed the data of patients with NPC who underwent CI in our hospital between 2006 and 2020. All subjects were found to be eligible according to the following inclusion criteria had NPC, received irradiation, underwent cochlear implant surgery, and had chronic otitis media with obstructive ET dysfunction.

A total of 9 patients with obstructive ET dysfunction and chronic otitis media underwent cochlear implant surgery. Seven patients with an inflamed ETs underwent a 2-stage operation. Two patients with obliterated ETs, we performed a single-stage CI surgery. Only 1 patient had otitis media effusion after the surgery.

With the proper management of chronic otitis media and ET dysfunction, cochlear implant is an effective treatment for irradiated patients with NPC when conventional hearing aids failed.

Restenosis and granulation formation are the most common complications. Balloon dilatation combined with cryotherapy and adjuvant topical medication is one treatment method. However, the efficacy of adjuvant topical medication is controversial, and the lack of efficacy may be related to the effective dose of the drug delivered to the submucosal layer of the lesion. Therefore, a tool with high efficiency for delivering medications to the submucosal layer via injection may play an important role in treatment. A hybrid knife (HK) with a pressure water jet traditionally used in endoscopy submucosal dissection to inject saline into the submucosa was employed here to inject medications for subglottic stenosis, followed by electrical excision. Here, we report the case of a man with complex subglottic stenosis who underwent balloon dilatation combined with cryotherapy and an adjuvant submucosal triamcinolone injection performed with an HK. The drug was delivered more efficiently into the submucosal layer, and the lumen of the trachea was patent. Performing a submucosal injection with an HK may be a new approach to deliver medications to the submucosal layer for the treatment of tracheal stenosis.
Somatic internal tandem duplication of 3' of
(
ITD) has been found in clear cell sarcomas of the kidney (CCSK), soft tissue undifferentiated round cell sarcomas/primitive myxoid mesenchymal tumors of infancy (URCS/PMMTI), and a subgroup of central nervous system high-grade neuroepithelial tumors (CNS-HGNET).
ITD+ tumors share morphologic features. Expression of OLIG2 and epidermal growth factor receptor (EGFR) has been reported in CNS-HGNET with
ITD. Here, we characterize OLIG2 and EGFR expression in URCS/PMMTI with BCOR ITD.

Paraffin blocks of 9 polymerase chain reaction-confirmed soft tissue BCOR ITD+ tumors (URCS/PMMTI) were immunophenotyped for OLIG2 and EGFR expression and scored semiquantitatively by percentage of positive cells and intensity of staining as negative, 1+, 2+, and 3+. Fluorescence in situ hybridization (FISH) for EGFR amplification was performed (amplification
/CEP7 ratio ≥2.0).

All 9 tumors showed membrane/cytoplasmic expression of EGFR, strong and diffuse (3+) in 8 cases; weak (+2) in 1.
