Monitoring biological and psychological measures throughout an entire season in male handball players
[EN] The aim of this study was to monitor biological markers of inflammation and oxidative stress, mood states, and recoverystress
states throughout an entire season in male handball players. Fourteen handball players (age 20.192.5 years) with a
regular training and competitive background in handball (11.093.7 years) from the same club volunteered to participate.
All participants completed 40 weeks of training. The training load was increased progressively throughout the season. Blood
samples were collected and questionnaires were administered during preparatory, competitive, and recovery periods. Blood
C-reactive protein and oxidized glutathione (GSSG) concentrations increased during periods of high load, while the
reduced/oxidized glutathione ratio (GSH/GSSG) decreased. These changes were accompanied by a significant increase in
total leukocyte count. Positive correlations were found between C-reactive protein, GSSG, GSH/GSSG ratio, and training
load. No changes were observed in the Total Mood Disturbance score of the Profile of Mood States (POMS). However,
scores on some Recovery-Stress Questionnaire for Athletes subscales, such as Injury, Physical Recovery, and Being in
Shape, correlated with training load. Findings indicate that during periods of high training load, handball players developed
a low grade of inflammation and oxidative state. Results support the usefulness of monitoring psychological and biological
markers of inflammation, oxidative stress, and training load during season.SIThis work was supported by the Acción Estratégica Sobre el Deporte, Spain (grant #2006-56141-C03- 01 to J.G. and grant #2006-56141-C03-02 to S.M.)
Accelerated partial breast irradiation using 3D conformal radiotherapy: Toxicity and cosmetic outcome
Purpose: The aim of this paper is to analyze the incidence of acute and late toxicity and cosmetic outcome in breast cancer patients submitted to breast conserving surgery and three-dimensional conformal radiotherapy (3D-CRT) to deliver accelerated partial breast irradiation (APBI). Methods and materials: 84 patients were treated with 3D-CRT for APBI. This technique was assessed in patients with low risk stage I breast cancer enrolled from September 2005 to July 2011. The prescribed dose was 34/38.5 Gy delivered in 10 fractions twice daily over 5 consecutive days. Four to five nocoplanar 6 MV beams were used. In all CT scans Gross Tumor Volume (GTV) was defined around the surgical clips. A 1.5 cm margin was added by defining a Clinical Target Volume (CTV). A margin of 1 cm was added to CTV to define the planning target volume (PTV). The doseevolume constraints were followed in accordance with the NSABP/RTOG protocol. Late toxicity was evaluated according to the RTOG grading schema. The cosmetic assessment was performed using the Harvard scale. Results: Median patient age was 66 years (range 51e87). Median follow-up was 36.5 months (range 13 e83). The overall incidence of acute skin toxicities was 46.4% for grade 1 and 1% for grade 2. The incidence of late toxicity was 16.7% for grade 1, 2.4% for grade 2 and 3.6% for grade 3. No grade 4 toxicity was observed. The most pronounced grade 2 late toxicity was telangiectasia, developed in three patients. Cosmetics results were excellent for 52%, good for 42%, fair for 5% and poor for 1% of the patients. There was no statistical correlation between toxicity rates and prescribed doses (p ÂĽ 0.33) or irradiated volume (p ÂĽ 0.45). Conclusions: APBI using 3D-CRT is technically feasible with very low acute and late toxicity. Long-term results are needed to assess its efficacy in reducing the incidence of breast relapse
Signs of Overload After an Intensified Training
[EN] This study investigated eff ects of a 9-week intensified aerobic training and 3-weeks of recovery
on signs of overload in 9 healthy active young
males. Blood and saliva samples were collected
and psychological questionnaires were administered
during baseline (T1), intermediate load
(T2), maximal load (T3), and recovery (T4) periods.
Maximal oxygen uptake increased and blood
lactate concentration decreased in T3, while running
time in a 3 000 m track fi eld test was significantly shorter. No signifi cant changes were
found in hematocrit, haemoglobin concentration,
white blood cell count, lactate dehydrogenase,
transaminases, interleukin-6, tumour necrosis
factor- α , myeloperoxidase and markers of oxidative
stress in plasma, or salivary cortisol and testosterone.
Increases in diff erent negative aff ectscales and in the total mood disturbance score of
the Profi le of Mood States were observed during
T3. Scores in the stress scales of the Recovery-
Stress Questionnaire for Athletes and in the State
Anxiety Scale of the State-Trait Anxiety Inventory
also showed signifi cant increases during T3.
The lack of eff ects in biomarkers together with
the changes observed in psychological assessment
indicates that an intensifi ed training can
produce psychological disturbances prone to
early overreaching development. Additionally, it
seems that psychological parameters are sensitive
markers to detect stress produced by load
increases.SIThis work was supported by the Acción Estratégica Sobre el Deporte, Spain (grants n ° 2006-56141-C03-01 to J. G., n ° 2006- 56141-C03-02 to S.M., and n ° 2006-56141-C03-03 to F.S.
Short-Term Outcomes of an ESDM Intervention in Italian Children with Autism Spectrum Disorder following the COVID-19 Lockdown
The COVID-19 pandemic caused a temporary lockdown period in Italy, during which the delivery of in-person treatment for children with autism spectrum disorder (ASD) in public health services was discontinued. This occurrence represented a crucial challenge for both families and professionals. We assessed the short-term outcomes of a sample of 18 children who received an early intervention with the Early Start Denver Model (ESDM), delivered at low intensity over one year in the pre-pandemic period, after six months of interruption of in-presence treatment due to lockdown restrictions. Children who received the ESDM treatment maintained their gains in sociocommunicative skills and did not exhibit any developmental regression. Additionally, there was evidence of a decrease in the restrictive and repetitive behavior (RRB) domain. The parents, who were already familiar with the principles of the ESDM, only received telehealth support from therapists that aimed to sustain the gains already achieved. We believe that it is always helpful to support parents in their daily lives by implementing interactional and play skills with their children to integrate and consolidate the results obtained in the individual interventions conducted by experienced therapists

Este estudo apresenta a experiĂŞncia vivenciada a partir do projeto de extensĂŁo "Catar para Transformar" do Instituto Federal do PiauĂ (IFPI), campus ParnaĂba, que buscou discutir, junto com os catadores de resĂduos sĂłlidos da Comunidade Parque JosĂ© EstevĂŁo, no municĂpio de ParnaĂba-PI, a importância do catador bem como caracterizar esta atividade, na percepção dos prĂłprios catadores. Visitas, oficinas e rodas de conversas foram realizadas na comunidade com temas sobre o trabalho do catador, questões ambientais, higiene, saĂşde e segurança no trabalho. Em ParnaĂba, a existĂŞncia do “lixĂŁo” ainda Ă© uma realidade para o municĂpio. Nesse contexto, nota-se que a atuação do catador se dá de forma individual, muitas vezes autĂ´noma, apesar da tentativa coletiva de formação de uma cooperativa. A experiĂŞncia aqui relatada foi bastante significativa, Ă medida que buscou refletir sobre o trabalho de catação no “lixĂŁo” do Parque JosĂ© EstevĂŁo, discutir junto com a comunidade e os catadores bem como servir de incentivo e proporcionar elementos para novas vivĂŞncias e estudos com outros grupos de trabalhadores vulneráveis
Compartmental tongue surgery for intermediate-advanced squamous cell carcinoma: A multicentric study
Background: A multicentric study was conducted on technical reproducibility of compartmental tongue surgery (CTS) in advanced tongue cancers (OTSCC) and comparison to standard wide margin surgery (SWMS). Methods: We studied 551 patients with OTSCC treated by CTS and 50 by SWMS. Oncological outcomes were analyzed. A propensity score was performed to compare survival endpoints for the two cohorts. Results: In the CTS group, survival and prognosis were significantly associated with positive lymph-nodes, extranodal extension, depth of invasion and involvement of the soft tissue connecting the tongue primary tumor to neck lymph nodes (T-N tract), independently from the center performing the surgery. SWMS versus CTS showed a HR Cause-Specific Survival (CSS) of 3.24 (95% CI: 1.71-6.11; p < 0.001); HR Loco-Regional Recurrence Free Survival (LRRFS) of 2.54 (95% CI: 1.47-4.40; p < 0.001); HR Overall Survival (OS) of 0.11 (95% CI: 0.01-0.77; p = 0.03). Conclusion: Performing the CTS could provide better CSS and LRRFS than SWMS regardless of the center performing the surgery, in advanced OTSSC
Survey on gynecological cancer treatment by Piedmont, Liguria, and Valle d’Aosta group of AIRO (Italian Association of Radiation Oncology)
Purpose : We focused the attention on radiation therapy practices about the gynecological malignancies in Piedmont, Liguria, and Valle d’Aosta to know the current treatment practice and to improve the quality of care.
Material and methods : We proposed a cognitive survey to evaluate the standard practice patterns for gynecological cancer management, adopted from 2012 to 2014 by radiotherapy (RT) centers with a large amount of gynecological cancer cases. There were three topics: 1. Taking care and multidisciplinary approach 2. Radiotherapy treatment and brachytherapy, 3. Follow-up.
Results : Nineteen centers treated gynecological malignancies and 12 of these had a multidisciplinary dedicated team. Radiotherapy option has been used in all clinical setting: definitive, adjuvant, and palliative. In general, 1978 patients were treated. There were 834 brachytherapy (BRT) treatments. The fusion between diagnostic imaging (magnetic resonance imaging – MRI, positron emission tomography – PET) and computed tomography (CT) simulation was used for contouring in all centers. Conformal RT and intensity modulated radiation therapy (IMRT) were the most frequent techniques. The image guided radiation therapy (IGRT) was used in 10/19 centers. There were 8 active BRT centers. Brachytherapy was performed both with radical intent and as boost, mostly by HDR (6/8 centers). The doses for exclusive BRT were between 20 to 30 Gy. The doses for BRT boost were between 10 and 20 Gy. Four centers used CT-MRI compatible applicators but only one used MRI for planning. The BRT plans on vaginal cuff were still performed on traditional radiographies in 2 centers. The plan sum was evaluated in only 1 center. Only 1 center performed in vivo dosimetry.
Conclusions : In the last three years, multidisciplinary approach, contouring, treatment techniques, doses, and control systems were similar in Liguria-Piedmont and Valle d’Aosta. However, the technology implementation didn’t translate in a real treatment innovation so far
Prognostic Relevance of Multi-Antigenic Myeloma-Specific T-Cell Assay in Patients with Monoclonal Gammopathies
: Multiple Myeloma (MM) typically originates from underlying precursor conditions, known as Monoclonal Gammopathy of Undetermined Significance (MGUS) and Smoldering Multiple Myeloma (SMM). Validated risk factors, related to the main features of the clonal plasma cells, are employed in the current prognostic models to assess long-term probabilities of progression to MM. In addition, new prognostic immunologic parameters, measuring protective MM-specific T-cell responses, could help to identify patients with shorter time-to-progression. In this report, we described a novel Multi-antigenic Myeloma-specific (MaMs) T-cell assay, based on ELISpot technology, providing simultaneous evaluation of T-cell responses towards ten different MM-associated antigens. When performed during long-term follow-up (mean 28 months) of 33 patients with either MGUS or SMM, such deca-antigenic myeloma-specific immunoassay allowed to significantly distinguish between stable vs. progressive disease (p < 0.001), independently from the Mayo Clinic risk category. Here, we report the first clinical experience showing that a wide (multi-antigen), standardized (irrespective to patients' HLA), MM-specific T-cell assay may routinely be applied, as a promising prognostic tool, during the follow-up of MGUS/SMM patients. Larger studies are needed to improve the antigenic panel and further explore the prognostic value of MaMs test in the risk assessment of patients with monoclonal gammopathies
Study of the Tissue Distribution of TLQP-21 in Mice Using [18F]JMV5763, a Radiolabeled Analog Prepared via [18F]Aluminum Fluoride Chelation Chemistry
TLQP-21 is a neuropeptide that is involved in the control of several physiological functions, including energy homeostasis. Since TLQP-21 could oppose the early phase of diet-induced obesity, it has raised a huge interest, but very little is known about its mechanisms of action on peripheral tissues. Our aim was to investigate TLQP-21 distribution in brain and peripheral tissues after systemic administration using positron emission tomography. We report here the radiolabeling of NODA-methyl phenylacetic acid (MPAA) functionalized JMV5763, a short analog of TLQP-21, with [18F]aluminum fluoride. Labeling of JMV5763 was initially performed manually, on a small scale, and then optimized and implemented on a fully automated radiosynthesis system. In the first experiment, mice were injected in the tail vein with [18F]JMV5763, and central and peripheral tissues were collected 13, 30, and 60 min after injection. Significant uptake of [18F]JMV5763 was found in stomach, intestine, kidney, liver, and adrenal gland. In the CNS, very low uptake values were measured in all tested areas, suggesting that the tracer does not efficiently cross the blood–brain barrier. Pretreatment with non-radioactive JMV5763 caused a significant reduction of tracer uptake only in stomach and intestine. In the second experiment, PET analysis was performed in vivo 10–120 min after i.v. [18F]JMV5763 administration. Results were consistent with those of the ex vivo determinations. PET images showed a progressive increase of [18F]JMV5763 uptake in intestine and stomach reaching a peak at 30 min, and decreasing at 120 min. Our results demonstrate that 18F-labeling of TLQP-21 analogs is a suitable method to study its distribution in the body
Drivers of Cyanobacterial Blooms in a Hypertrophic Lagoon
The Curonian Lagoon is Europe's largest lagoon and one of the most seriously impacted by harmful blooms of cyanobacteria. Intensive studies over the past 20 years have allowed us to identify the major drivers determining the composition and spatial extent of hyperblooms in this system. We summarize and discuss the main outcomes of these studies and provide an updated, conceptual scheme of the multiple interactions between climatic and hydrologic factors, and their influence on internal and external processes that promote cyanobacterial blooms. Retrospective analysis of remote sensed images demonstrated the variability of blooms in terms of timing, extension and intensity, suggesting that they occur only under specific circumstances. Monthly analysis of nutrient loads and stoichiometry from the principal tributary (Nemunas River) revealed large interannual differences in the delivery of key elements, but summer months were always characterized by a strong dissolved inorganic N (and Si) limitation, that depresses diatoms and favors the dominance of cyanobacteria. Cyanobacteria blooms occurred during high water temperatures, long water residence time and low-wind conditions. The blooms induce transient (night-time) hypoxia, which stimulates the release of iron-bound P, producing a positive feedback for blooms of N-fixing cyanobacteria. Consumer-mediated nutrient recycling by dreissenid mussels, chironomid larvae, cyprinids and large bird colonies, may also affect P availability, but their role as drivers of cyanobacteria blooms is understudied
