Abstract

Due to the COVID-19 pandemic in the 2019–2020 season, swimming competitions and training have been limited leading to a setback in performances. The study analyzed if, during the subsequent season, swimmers’ have been able to regain the lost performance. Swimming time trends were analyzed comparing Tokyo with Rio Olympics and with mathematically predicted results. The gap between the gold medalist and the last finalist, and the differences between men and women have also been considered. Swimming competition results of females and males, in 100 m and 200 m Freestyle and Backstroke, were collected from the Olympics’ official website. Results showed that at Tokyo Olympics almost all swimmers’ times improved as compared to Rio’s. Analysis of performance trends highlighted that performance progression does not proceed in a linear fashion and that is best predicted by more recent results. Women’s progression was higher than men’s and the gap between the first and last finalist constantly decreased, except for the Tokyo Olympics. In conclusion, the unprecedented Tokyo Olympic Games and qualification year seems not to have disrupted all Olympic swimmers’ performance, suggesting that stakeholders support and athlete’s coping ability might safeguard the subsistence of performance.

Abstract

Clinical features and natural history of coronavirus disease 2019 (COVID-19) differ widely among different countries and during different phases of the pandemia. Here, we aimed to evaluate the case fatality rate (CFR) and to identify predictors of mortality in a cohort of COVID-19 patients admitted to three hospitals of Northern Italy between March 1 and April 28, 2020. All these patients had a confirmed diagnosis of SARS-CoV-2 infection by molecular methods. During the study period 504/1697 patients died; thus, overall CFR was 29.7%. We looked for predictors of mortality in a subgroup of 486 patients (239 males, 59%; median age 71 years) for whom sufficient clinical data were available at data cut-off. Among the demographic and clinical variables considered, age, a diagnosis of cancer, obesity and current smoking independently predicted mortality. When laboratory data were added to the model in a further subgroup of patients, age, the diagnosis of cancer, and the baseline PaO2/FiO2 ratio were identified as independent predictors of mortality. In conclusion, the CFR of hospitalized patients in Northern Italy during the ascending phase of the COVID-19 pandemic approached 30%. The identification of mortality predictors might contribute to better stratification of individual patient risk.

Abstract

Introduction. The clinical course of Coronavirus Disease 2019 (COVID-19) is highly heterogenous, ranging from asymptomatic to fatal forms. The identification of clinical and laboratory predictors of poor prognosis may assist clinicians in monitoring strategies and therapeutic decisions. Materials and Methods. In this study, we retrospectively assessed the prognostic value of a simple tool, the complete blood count, on a cohort of 664 patients ( F 260; 39%, median age 70 (56-81) years) hospitalized for COVID-19 in Northern Italy. We collected demographic data along with complete blood cell count; moreover, the outcome of the hospital in-stay was recorded. Results. At data cut-off, 221/664 patients (33.3%) had died and 453/664 (66.7%) had been discharged. Red cell distribution width (RDW) ( χ 2 10.4; p < 0.001 ), neutrophil-to-lymphocyte (NL) ratio ( χ 2 7.6; p = 0.006 ), and platelet count ( χ 2 5.39; p = 0.02 ), along with age ( χ 2 87.6; p < 0.001 ) and gender ( χ 2 17.3; p < 0.001 ), accurately predicted in-hospital mortality. Hemoglobin levels were not associated with mortality. We also identified the best cut-off for mortality prediction: a NL ratio > 4.68 was characterized by an odds ratio for in-hospital mortality OR = 3.40 (2.40-4.82), while the OR for a RDW > 13.7 % was 4.09 (2.87-5.83); a platelet count > 166,000 /μL was, conversely, protective (OR: 0.45 (0.32-0.63)). Conclusion. Our findings arise the opportunity of stratifying COVID-19 severity according to simple lab parameters, which may drive clinical decisions about monitoring and treatment.

Abstract

Atherosclerosis, a complex cardiovascular disease, is a leading cause of mortality and morbidity worldwide. Oxidative stress and inflammation are both involved in the development of atherosclerotic plaque as they increase the biological processes associated with this pathology, such as endothelial dysfunction and macrophage recruitment and adhesion. Atherosclerotic plaque rupture leading to major ischemic events is the result of vulnerable plaque progression, which is a result of the detrimental effect of oxidative stress and inflammation on risk factors for atherosclerotic plaque rupture, such as intraplaque hemorrhage, neovascularization, and fibrous cap thickness. Thus, both are key targets for primary and secondary interventions. It is well recognized that chronic physical activity attenuates oxidative stress in healthy subjects via the improvement of antioxidant enzyme capacities and inflammation via the enhancement of anti-inflammatory molecules. Moreover, it was recently shown that chronic physical activity could decrease oxidative stress and inflammation in atherosclerotic patients. The aim of this review is to summarize the role of oxidative stress and inflammation in atherosclerosis and the results of therapeutic interventions targeting them in both preclinical and clinical studies. The effects of chronic physical activity on these two key processes are then reviewed in vulnerable atherosclerotic plaques in both coronary and carotid arteries.

Abstract

Cellular DNA content of solid tumors can be determined either from fresh, frozen, or formalin fixed, paraffin-embedded tissues. However, discordant results have been obtained using the paraffin-embedded technique, and lack of abnormal DNA stemlines in the paraffin-embedded as compared to either fresh or frozen tissues has been reported. In this study we evaluated the validity of nuclear extraction method from paraffin-embedded tissues, using 75 breast carcinomas whose DNA content was previously analyzed from frozen tissue and resulted either normal (12 cases) or abnormal (63 cases). From representative paraffin blocks, nuclei were extracted following Hedley's technique. The results revealed excellent cell counting and good histogram resolution from all paraffin samples; the loss of G2M abnormal peak in eight histograms with abnormal stemline did not compromise the correct interpretation of DNA content. In addition, the comparison between DNA indices obtained from corresponding paraffin and frozen samples showed a good correlation in 69 cases (r = 94); discordance in six cases was demonstrated to be related to tumor heterogeneity. In conclusion the paraffin extraction method is a sensible, and reliable technique, which can be applied for DNA flow cytometric studies on archival cases, as well as whenever fresh sample from the tumor is not obtainable.

Abstract

Clinical features and natural history of coronavirus disease 2019 (COVID-19) differ widely among different countries and during different phases of the pandemia. Here, we aimed to evaluate the case fatality rate (CFR) and to identify predictors of mortality in a cohort of COVID-19 patients admitted to three hospitals of Northern Italy between March 1 and April 28, 2020. All these patients had a confirmed diagnosis of SARS-CoV-2 infection by molecular methods. During the study period 504/1697 patients died; thus, overall CFR was 29.7%. We looked for predictors of mortality in a subgroup of 486 patients (239 males, 59%; median age 71 years) for whom sufficient clinical data were available at data cut-off. Among the demographic and clinical variables considered, age, a diagnosis of cancer, obesity and current smoking independently predicted mortality. When laboratory data were added to the model in a further subgroup of patients, age, the diagnosis of cancer, and the baseline PaO2/FiO2 ratio were identified as independent predictors of mortality. In conclusion, the CFR of hospitalized patients in Northern Italy during the ascending phase of the COVID-19 pandemic approached 30%. The identification of mortality predictors might contribute to better stratification of individual patient risk.

Abstract

Studio dei caratteri linguistico-comunicativi di un campione di scritture di guerra prodotte (o ricevute) da militari meridionali durante o immediatamente dopo la Grande guerra. I testi esaminati sono divisi in tre classi, secondo il livello socio-culturale degli scriventi. Nei testi scritti da ufficiali e sottufficiali emergono orrore per la guerra ma anche accettazione delle ragioni che hanno condotto all’ingresso dell’Italia nel conflitto; nelle scritture dei semicolti, invece, prevale un’obbediente rassegnazione, sorretta dal conforto della fede e dell’affetto dei familiari lontani. Una minacciosa prospettiva di ribellione è evocata nella lettera anonima di una popolana napoletana. The subject of this paper is the analysis of the linguistic and pragmatic features of a sample of texts written (or received) by soldiers from Southern Italy during or right after the First World War. The examined texts are divided into three classes, corresponding to the different socio-cultural levels of their authors. In their texts the officers generally express their horror at the atrocities of war but also they agree with the reasons that drove Italy to go to war. Instead, a resigned obedience, comforted by the Christian faith and by the love of the family members far from the front line, dominates in the texts written by the so called “semicolti” (i.e. the soldiers with lower level of education). A riot threat is called up in her letter by an anonymous Neapolitan woman of lower class.

20. Which of the Physiological vs. Critical Speed Is a Determinant of Modern Pentathlon 200 m Front Crawl Swimming Performance: The Influence of Protocol and Ergometer vs. Swimming Pool Conditions.

Author

Abstract

Background: Modern pentathlon includes horse riding, fencing, swimming, shooting and cross-country running. Events can last many hours during which the athletes face almost maximal energy and physiological demands, and fatigue. Early recognition and prevention of injuries and overuse syndromes can be achieved by refining the individual training loads. The purpose of the study was to determine which parameter could be the most accurate predictor of swimming working capacity determinants in pentathletes., Methods: Fourteen male pentathletes performed a continuous maximal incremental test in the swimming flume ergometer to measure peak oxygen uptake (VO 2 peak), and five swimming tests in a 50 m swimming pool to detect critical velocity (CV); velocity at 2 and 4 mM·L -1 of blood lactate (v2, v4) and energy cost (EC)., Results: The 200 m swimming time was 2:18-2:32 m:s (340 FINA points). CV was 1.21 ± 0.04 m·s -1 , v2 was 1.14 ± 0.09 and v4 1.23 ± 0.08 m·s -1 . VO 2 peak was 3540.1 ± 306.2 mL·min -1 or 48.8 ± 4.6 mL·kg -1 ·min -1 . EC at 1.24 m·s -1 was 45.7 ± 2.4 mL·kg -1 ·min -1 . Our main finding was the large correlation of CV with 200 m swimming performance; Conclusions: Among all the protocols analysed, CV is the most predictive and discriminative of individual swimming performance in this group of pentathletes. It appears as the most suitable test to constantly refine their swimming training loads for both performance enhancement and health promotion.

Abstract

Atherosclerosis is associated with low-grade inflammation involving circulating monocytes. It has been shown that the levels of intermediate pro-inflammatory monocytes are associated with cardiovascular mortality and risk of ischemic stroke. It also has been shown that physical activity (PA) decreases inflammation markers, incidence of strokes, and mortality. In this cross-sectional study, we tested the effect of PA on circulating monocytes phenotype rate. A total of 29 patients with a carotid stenosis > 50% were recruited. Levels of physical activity (MET.min/week) were measured by the GPAQ questionnaire, arterial samples of blood were collected to analyze monocyte phenotype (classical, intermediate and non-classical) assessed by flow cytometry, and venous blood samples were used to dose antioxidant activity and oxidative damage. Antioxidant capacity was reduced and oxidative damage increased in patients. There was a significant decrease in the percentage of classical and intermediate monocytes in moderately active patients as compared with non-active and highly active patients. Inversely, the rate of non-classical monocytes increased in moderately active patients. Intense PA appears to blunt the beneficial effects of moderate PA. Our study also suggests that PA could be beneficial in such patients by reducing the rate of intermediate monocytes known to predict the risk of ischemic stroke and by increasing the non-classical monocytes involved in lesions’ healing. Nevertheless, a longitudinal study would be necessary to confirm this hypothesis.

Abstract

Introduction: Swimming represents a crucial capacity for water polo players. Several studies have proposed different protocols to understand the incidence of this capacity on water polo performance and to improve the players' swimming assessment. This work aimed to provide a systematic review regarding the current status of physiological swimming tests for water polo players with the purpose to furnish a complete framework to coaches and fully exploit recent advances of scientific research to enhance performance assessment and monitoring of the athletes., Evidence Acquisition: PubMed, Google Scholar, Scopus, and Science Direct were searched for relevant studies published from January 2000 to January 2021. The study dealt with a specific water test and performed in a horizontal swimming position without ball were included., Evidence Synthesis: Twenty-three studies met the inclusion criteria. The results indicate the physiological assessment of water polo players might be divided into two areas concerning the swimming evaluation: swimming sprint tests and endurance swimming test. Furthermore, endurance swimming tests may be split into two subgroups: anaerobic-endurance swimming and aerobic-endurance swimming tests. Each of these areas evaluates a specific conditional capacity through swimming protocols based on the players' individual profile and water polo demands., Conclusions: In the last years, scientific research has studied the typical ability of each water polo rule and of every athletes' level that represents this sport. The results have oriented the researchers to choose different protocols to evaluate each swimming capacity that characterizes a particular phase of the water polo match.

Abstract

Water exercise provides a workload in every direction of motion for training in a reduced impact environment. The selection of an appropriate physical activity and an individual exercise prescription are essential to obtain training effects. The aim of the present study was to determine individualised relative exercise intensities at four speeds of motion for water cycling and water running. Running was tested both in buoyancy and with the feet in contact with the bottom of the pool. To this purpose, gas exchanges, heart rate, and blood lactate were measured in each test session. Fourteen active, healthy females (23.2 ± 1.6 years) underwent a dry land maximal incremental protocol to exhaustion on a treadmill and hydrobike (HB); they engaged in water running with ground contact (RC) and water running suspended (RS) tests in a swimming pool at 30, 40, 50, and 60 cycles per minute (cpm), submerged at the individual xiphoid level. The four motion speeds of the three water exercise modalities ranged from 50% to 95% of the maximal heart rate and the maximal oxygen uptake, representing a moderate-to-vigorous training stimulus. RS elicited the lowest oxygen consumption, whereas HB demanded the significantly highest oxygen consumption and presented the highest blood lactate accumulation, with vigorous intensity being reached at 50 cpm and near maximal intensity at 60 cpm. It appears that water cycling could be more suitable for athletic training, whereas water running could be more appropriate for health and fitness purposes.

Abstract

The aim of the study was to analyse the fitness level of young horse riders before and after 12 weeks of training restrictions instituted due to the COVID-19 emergency. Anthropometrical measure assessment and an eight-items fitness test battery were administered to 61 puberal and adolescent female amateur horse riders. Subjects were evaluated within 3 weeks before (pre-tests) the period of training restrictions and on the first day of normal training after it (post-tests). Post-test results showed significant increases in body weight (Z: −1.732; p value: 0.001; ES: −0.157) and BMI (F: 9.918; p value: 0.003; ES: 0.146), whilst the performance in hand grip and abdominal strength, hip mobility, and 10 × 5 m Shuttle and Cooper 12 min tests’ outcomes significantly decreased (F: 29.779; p value: 0.001 F: 29.779; p value: 0.001 F: 29.779; p value: 0.001 F: 29.779; p value: 0.001 F: 29.779; p value: 0.001, respectively). Correlation analysis revealed that riders’ experience was significantly correlated with hand grip (p < 0.01), leg strength (p < 0.01), hip mobility (p < 0.05), and 5 × 10 m Shuttle (p < 0.01) and the Cooper 12 min (p < 0.01) test results. It could be suggested that equestrian activities could produce a higher fitness level in puberal and adolescent riders, whilst home-based, unsupervised, and unattentively planned training during the twelve weeks of training restrictions might be insufficient to maintain it.

Abstract

Due to the COVID-19 pandemic in the 2019-2020 season, swimming competitions and training have been limited leading to a setback in performances. The study analyzed if, during the subsequent season, swimmers' have been able to regain the lost performance. Swimming time trends were analyzed comparing Tokyo with Rio Olympics and with mathematically predicted results. The gap between the gold medalist and the last finalist, and the differences between men and women have also been considered. Swimming competition results of females and males, in 100 m and 200 m Freestyle and Backstroke, were collected from the Olympics' official website. Results showed that at Tokyo Olympics almost all swimmers' times improved as compared to Rio's. Analysis of performance trends highlighted that performance progression does not proceed in a linear fashion and that is best predicted by more recent results. Women's progression was higher than men's and the gap between the first and last finalist constantly decreased, except for the Tokyo Olympics. In conclusion, the unprecedented Tokyo Olympic Games and qualification year seems not to have disrupted all Olympic swimmers' performance, suggesting that stakeholders support and athlete's coping ability might safeguard the subsistence of performance.

Abstract

Introduction: The clinical course of Coronavirus Disease 2019 (COVID-19) is highly heterogenous, ranging from asymptomatic to fatal forms. The identification of clinical and laboratory predictors of poor prognosis may assist clinicians in monitoring strategies and therapeutic decisions., Materials and Methods: In this study, we retrospectively assessed the prognostic value of a simple tool, the complete blood count, on a cohort of 664 patients ( F 260; 39%, median age 70 (56-81) years) hospitalized for COVID-19 in Northern Italy. We collected demographic data along with complete blood cell count; moreover, the outcome of the hospital in-stay was recorded., Results: At data cut-off, 221/664 patients (33.3%) had died and 453/664 (66.7%) had been discharged. Red cell distribution width (RDW) ( χ 2 10.4; p < 0.001), neutrophil-to-lymphocyte (NL) ratio ( χ 2 7.6; p = 0.006), and platelet count ( χ 2 5.39; p = 0.02), along with age ( χ 2 87.6; p < 0.001) and gender ( χ 2 17.3; p < 0.001), accurately predicted in-hospital mortality. Hemoglobin levels were not associated with mortality. We also identified the best cut-off for mortality prediction: a NL ratio > 4.68 was characterized by an odds ratio for in-hospital mortality (OR) = 3.40 (2.40-4.82), while the OR for a RDW > 13.7% was 4.09 (2.87-5.83); a platelet count > 166,000/ μ L was, conversely, protective (OR: 0.45 (0.32-0.63))., Conclusion: Our findings arise the opportunity of stratifying COVID-19 severity according to simple lab parameters, which may drive clinical decisions about monitoring and treatment., Competing Interests: The authors have no conflict of interest to declare., (Copyright © 2021 Mattia Bellan et al.)

Abstract

Objective: The present study aimed to assess if changes in speed and stroke parameters, as measured by an inertial sensor during a maximal effort swimming test, could provide an effective detection of anaerobic capacity in elite swimmers., Approach: Fourteen elite swimmers performed a 75 m maximal swimming test. Changes in speed and stroke parameters, estimated by a body-worn inertial sensor, were analysed to provide insight into stroke mechanics during swimming. Their relationships with the output of the Wingate Anaerobic Test were analysed. Best times in competition were also considered to assess swimmer's performance., Main Results: Mean power measured using the Wingate cycle ergometer test highly correlated with mean speed attained by the swimmers during the proposed 75 m swimming test (R range: .700-.809, p   <  .05). Mean power in the Wingate Anaerobic Test and mean speed in the 75 m swimming test highly correlated with best times attained by the swimmers (R range: .736-.855, p   <  .01; R range: .659-.952, p   <  .05, for Wingate and 75 m swimming test, respectively). Moreover, stroke variables were investigated: in this regard, a significant decrease in stroke rate and swimming speed and a significant increase in stroke length were observed between the first and the third lap (p   <  .01)., Significance: The present in-water free swimming test provided insight into specific physiological/mechanical aspects of elite swimmers. The correlation of the swimming and the Wingate tests with swimmer's performance in competition confirms that they both reflect the skills and anaerobic qualities a swimmer uses in a race. The wearable inertial sensor could represent a feasible solution to evaluate stroke parameters, allowing a timely follow-up of variations in swimming biomechanics along the course of the test and the identification of differences in biomechanical strategy between swimmers. This analysis is of great interest for swimmers and coaches to characterise swimmer's technique weakness and strength, and to plan individual race pacing strategy.

Abstract

Physical activity is frequently used as a strategy to decrease pathogenesis and improve outcomes in chronic pathologies such as metabolic or cardiac diseases. In mice, it has been shown that voluntary wheel running (VWR) could induce an aerobic training effect and may provide a means of exploring the relationship between physical activity and the progression of pathology, or the effect of a drug on locomotor activity. To the best of our knowledge, in vivo magnetic resonance imaging (MRI) and other non-invasive methods had not been investigated for training evaluation in mice; therefore, it was proposed to test an MRI method coupled with a cardiorespiratory gating system on C57Bl/6 mice for in vivo heart anatomical and functional characterization in both trained and untrained animals. Twenty mice were either assigned to a 12-week VWR program or to a control group (CON - no wheel in the cage). At week 12, MRI scans showed an increase in the left ventricular (LV) wall mass in the VWR group compared with the CON group. The ex vivo measurements also found an increase in the heart and LV weight, as well as an increase in oxidative enzyme activities (i.e. cytochrome c oxidase [COx] in the soleus). In addition, correlations have been observed between ex vivo LV/body weight ratio, COx activity in the soleus and in vivo MRI LV wall mass/body weight. In conclusion, mouse cardiac MRI methods coupled with a cardio-respiratory gating system are sufficiently effective and feasible for non-invasive, training-induced heart hypertrophy characterization, and may be used for longitudinal training level follow-up in mouse models of cardiovascular and metabolic diseases.

Abstract

There is evidence that pulmonary arterial hypertension plays a major role in the occurrence of high altitude pulmonary edema (HAPE). We tested the hypothesis that the pulmonary arterial systolic pressure response to a challenge associated with hypoxia and mild exercise may be considered a predictive factor of HAPE. Pulmonary arterial systolic pressure was measured by Doppler echocardiography in 8 HAPE susceptible (HAPE-S) subjects and 8 HAPE resistant mountaineers (HAPE-R) during a hypoxic exercise challenge established by the French Association for Sport Medicine (Richalet's test). Pulmonary arterial systolic pressure during hypoxic exercise allowed a significant discrimination between the groups, although an overlap of values was observed. When expressed as individual variations from baseline to hypoxic exercise level however, we found a highly significant difference. No overlap was observed between HAPE-R (range: 6.7-18.5 mmHg) and HAPE-S (range: 19.2-30.4 mmHg) groups, with a cut-off value at 19 mmHg. Plasma Vascular Endothelial growth factor (VEGF) and malondialdehyde (MDA) increased in response to hypoxic exercise only in HAPE-S group. Individual increases in pulmonary arterial systolic pressure during hypoxic exercise from basal resting normoxic values seem relevant to estimate HAPE susceptibility when measured during the Richalet's test., (Copyright © 2011 Elsevier B.V.

Abstract

Thirty cases of colorectal carcinoma have been evaluated for proliferative activity with the monoclonal antibody Ki 67 and with flow cytometry for ploidy, DNA index and the S-phase fraction. In the series, 30% of tumours were strictly aneuploid, 23.8% tetraploid and 45% diploid: "non diploid" cases accounted for 53.8%. The mean comprehensive values of DNA index, percent S-phase and Ki 67 positive fraction were 1.4%, 11.5% and 50%, respectively. The parameters considered showed no statistically significant correlation with each other or with the common histo-pathologic parameters, such as grading and staging. The prevalent prognostic importance of ploidy compared to DNA index is emphasized, and particular attention is paid to diploid cases with a high growth fraction (S-phase fraction), which could make up an "at risk" category. Therefore, we attempted to identify subsets, within groups of the same histologic stage, with a different evolutive significance in relation to DNA content, percentage of positivity to Ki 67, S-phase fraction and ploidy. With such a multi-parametric approach, particular groups of patients at risk could be defined, which are perhaps more sensitive to specific support therapies.

Abstract

Thirty-six Sicilian women (mean age 26.2 years, range 18-34) who had chosen to breastfeed their newborn babies were included in the study. A semi-structured questionnaire was used by a pediatrician to interview all subjects 4 months after the birth. 94.7% of the women interviewed (36 cases) said that they had derived pleasure from breastfeeding while 5.3% (2 cases) stated that they had not. 44.7% (15 cases) experienced strong uterine contractions (described ad "cramps") during breastfeeding (these were described as occurring "often" in ten cases and "rarely" in five cases); in 6 (35.3%) out of 17 patients "uterine cramps" were a cause of "pleasure", whereas in the rest (64.7%) they were described as "bothersome" (5 cases), "painful" (2 cases) or "indifferent" (4 cases). If sexual pleasure is derived from the breastfeeding one's offspring, it may be to a certain extent represent, together with the joy of bringing up children, a compensatory substitute for the couple's sex life following the change of the woman's centre of attention from the sexual pole to that of the continuation of the species.
