Overtraining is an imbalance between training and recovery, exercise and exercise capacity, stress and stress tolerance. Stress is the sum of training and nontraining stress factors. Peripheral (short-term overtraining, STO) or peripheral and central fatigue may result (long-term overtraining, LTO). STO lasting a few days up to 2 wk is termed overreaching. STO is associated with fatigue, reduction, or stagnation of the 4 LT performance capacity (performance at 4 mmol lactate or comparable criterion), reduction of maximum performance capacity, and brief competitive incompetence. Recovery is achieved within days, so the prognosis is favorable. LTO lasting weeks or months causes overtraining syndrome or staleness. The symptomatology associated with overtraining syndrome has changed over the last 50 yr from excitation and restlessness (so-called sympathetic form) to phlegmatic behavior and inhibition (so-called parasympathetic form). Increased volume of training at a high-intensity level is likely the culprit. The parasympathetic form of overtraining syndrome dominates in endurance sports. Accumulation of exercise and nonexercise fatigue, stagnation, or reduction of the 4 LT performance capacity, reduction in maximum performance capacity, mood state disturbances, muscle soreness/stiffness, and long-term competitive incompetence can be expected. Complete recovery requires weeks and months, so the prognosis is unfavorable. Other optional or further confirmation requiring findings include changes in blood chemistry variables, hormone levels, and nocturnal urinary catecholamine excretion. Based on the findings reported, recommendations for training monitoring can be made, but their relevance in the practice must still be clarified.

A chemical solution-deposited multilayer system of SrTiO3 ("STO")/La0.5Sr0.5CoO3 ("LSCO") on a platinized wafer with a layer sequence Pt/TiO2/SiO2/Si(bulk) has been investigated by dynamic SIMS (secondary ion mass spectroscopy) and TEM (transmission electron microscopy); element determination was performed with EELS (electron energy-loss spectroscopy). The STO layer is intended to serve as a dielectric layer for a microelectronic capacitor; the conducting LSCO layer is a buffer layer intended to eliminate fatigue effects which usually occur at the STO/Pt interface. The SIMS depth profiles obtained for the main components revealed intense diffusion processes which must have occurred during the deposition/crystallization processes. Ti is found to diffuse from the (insulating) STO layer into the conductive LSCO layer where a region of constant concentration is observable. TEM-EELS experiments showed that these Ti plateaus are caused by precipitates approximately 20-80 nm in diameter.

We assessed the quality of life (QOL) at least one year after sequential chemoradiotherapy for the treatment of localized gastric diffuse large B-cell lymphoma (DLBCL). We used the EORTC Quality of Life Questionnaire for Stomach Cancer (EORTC QLQ-STO22). Among the 45 patients available at the one-year follow-up after radiation therapy, 40 patients completed the EORTC QLQ-STO22 questionnaire. Their median age was 54.5 (range, 20-70 years). Social functioning was most adversely affected among the respondents with a score of 59, whereas other functions and the global scales were preserved above a score of 70 by linearly transformed values. Fatigue, the financial impact and specific emotional problems such as "thinking about their illness" (STO-ANX) and "worry about weight loss or future health" (STO-BI) were persistently bothersome for some patients. Other stomach-related symptoms such as dysphagia, pain, or reflux were negligible at 1 year after treatment. Therefore, this organ-preserving combined approach was effective for the maintenance of the QOL and minimization of stomach abnormalities in patients with gastric lymphoma.

The STO-BANG questionnaire, S standing for snore, T tired, O observed apneas, P pressure (arterial hypertension), B BMI (body mass index > 35 kg/ m2), A age (> 50 years old), N neck circumference (> 40 cm), G gender (male); is a simple tool that enables the detection of patients with obstructive sleep apnea syndrome (OSA). If the patient adds 3 or more points, it is considered to have a high probability of having this disease. Our goal was to evaluate the capacity of the STOP-BANG questionnaire and to compare it with the ability of a sleep trained pulmonologist in determining the probability of OSA. A retrospective analysis of 327 patients suspected of having this condition was performed. One hundred and seventy-one were males (52.3%), 49.8 years old (37.9-61.7), BMI 38.7 kg/m2 (32.5-46), neck circumference 44 cm (41-47.5), 311 snorers (95.1%), 232 with daytime sleepiness or usual tiredness (70.9%), 206 with observed apneas (63%), 169 with arterial hypertension (51.7%), normal polysomnography 42 (12.9%), mild 65 (19.9%), moderate 59 (18%), severe 161 (49.2%). The STOP-BANG's sensibility and specificity, taking as a cut-off point a respiratory disturbance index (RDI) > or = to 15, was 99.1% and 14.0% respectively, area under curve (AUC) 0.755 (0.704-0.800), the values for the PR actioner's ability were 89.1% and 58.9% respectively, AUC 0.550 (0.542-0.638). The STOP-BANG questionnaire is easy to implement as a screening tool.
