Dynamic inertial analysis of the technical boxing gesture of Jab

The purpose of this study is to analyze the inertial dynamics of the Jab technical gesture in boxing. The target is to test and establish with the precision of the latest generation inertial technology the real physical parameters of the mechanical components of the technical gesture subjected to analysis to use, in the event of an expected congruence, the parameters obtained as key elements in the project of sports training investigated for performative purposes, given that the literature on this subject is scarce and sometimes with data obtained using non-state-of-the-art equipment and therefore not reliable. Five boxers (n = 5) took part in this research, considered sufficient for an exploratory study, respectively two female (n = 2), (18.5 ± 6.4 years, weight 63.7 ± 0.4 kg, height 169 ± 1.4 cm; arm length 69.5 ± 2.1 cm) and three male (n = 3), (23.0 ± 3.5 years, weight 80.0 ± 7.0 kg, height 184.3 ± 7.1 cm; arm length 79.7 ± 2.5 cm). These athletes were from different levels of experience, also to obtain specific threshold data in the various stadiums, however, all participating in national level competitions (elitè level). From the dataset, it’s possible to appreciate a different average acceleration value in the Jab execution phase between 8.65 m/s² (woman) and 13.85 m/s² (man) of the stroke, statistically significant (p <0.05), even in the small sample. The same situation is true for the torsion phase of the trunk between the best performing male boxer (boxer 1) and the best female boxer (boxer 5) respectively 0.733 vs 0.338 g² (p <0.05). This allows us to understand how gender and category differences are a key element in relation to the training planning of the discipline and that often turn out to be quite generic and that doesn’t take into account accurately and weighed the differences and what are the values to be respected in the specific training workload and also in the performance level of the exercises necessary to achieve those physiological conditions and techniques useful for performance improvement. The differences in this sample were also evident between individuals of the same gender and level

Spontaneous and iatrogenic ovarian hyperstimulation syndrome in the absence of FSHR mutations: a case report of two unexpected cases

Background: Ovarian hyperstimulation syndrome (OHSS) is a complication of controlled ovarian hyperstimulation (COH). It is a potentially life-threatening condition that usually occurs either after human chorionic gonadotropins (hCG) administration in susceptible patients or as a result of an implanting pregnancy, regardless of whether it was achieved by natural conception or infertility treatments. Despite many years of clinical experience regarding the adoption of preventive measures and the identification of patients at high risk, the pathophysiology of OHSS is poorly understood and no reliable predictive risk factors have been identified. Cases presentation: We report about two unexpected cases of OHSS following infertility treatments, occurring after freeze-all strategy with embryo cryopreservation approaches. The first case developed spontaneous OHSS (sOHSS), despite efforts to prevent its manifestation by a segmentation approach, including frozen embryo replacement cycle. The second case developed a late form of iatrogenic OHSS (iOHSS), even though the absence of any risk factors. No mutations in the follicle-stimulating hormone (FSH) receptor (FSHR)-encoding gene were detected, suggesting that the high levels of hCG due to the twin implanting pregnancies could be the only triggering factor of OHSS outbreak. Conclusion: Freeze-all strategy with embryo cryopreservation cannot entirely prevent the development of OHSS, which may occur in its spontaneous form independently from the FSHR genotype. Although OHSS remains a rare event, all infertile patients requiring ovulation induction or controlled ovarian stimulation (COS) may be at potential risk of OHSS, either in the presence or in the absence of risk factors. We suggest closely monitoring cases of pregnancy following infertility treatments in order to provide early diagnosis and adopt the conservative management

Telehealth in oncofertility and breast cancer patients during COVID-19: preliminary results of insenoallasalute.it project

Abstract. – OBJECTIVE: Breast cancer (BC) is the leading diagnosis in premenopausal patients. Lockdown measures during COVID-19 pandemic reduced facilities for premenopausal patients, impairing oncological and reproductive health. To reduce its effect, a telehealth program called insenoallasalute.it was designed in Italy. PATIENTS AND METHODS: A national-based multicentric observational study was undertaken by insenoallasalute.it study group (Italian Ministry of Health, Modena Hospital and Tor Vergata University Hospital) to raise awareness among women on a) BC and its negative role on reproductive health; b) increase adherence to screening programs and self-examination; c) present oncofertility strategies. A webbased platform with two sections was designed: an informative section and a telehealth application activated with a mobile one-time password. After a self-evaluation test to select premenopausal women with maternal desire and family or personal history for BC or ovarian cancer, and premenopausal women with maternity desires with prior medically assisted procreation, a dedicated agenda for telehealth evaluation was displayed and planned. In case the patients fulfilled the criteria for further evaluation, they were invited to perform an outpatient evaluation in one of the pilot centers. RESULTS: From July 2021 to December 2021, 2,830 single accounts were activated, and 2,450 (86.57%) completed the tests. 53 patients were selected to undergo telehealth consultation and 40 (80.0%) scheduled the telehealth visit. 6 patients underwent surgery in the study centers. CONCLUSIONS: In our experience insenoallasalute.it embodied an innovative solution to spread BC awareness, BC screening program, and oncofertility opportunities in the oncological population

Maintaining good practice in breast cancer management and reducing the carbon footprint of care: study protocol and preliminary results

Objective: Health care accounts for up to 8-10% of greenhouse emission yearly in the US and surgical room contributes an estimated 25-30% of hospital waste. Despite the major role of greenhouse emissions because of surgery, little has been done by surgeons to reduce their impact. In this paper, we present a multicentric retrospective analysis to evaluate the carbon footprint of the most common breast surgical treatment and a preliminary analysis of our results. Patients and Methods: Retrospective analysis with processed-based life cycle assessment (LCA) has been obtained to determine carbon footprint of different surgical procedures. In our preliminary study, we enrolled all consecutive patients undergoing breast conserving procedure (BCP) between 9th March 2019 and 9th March 2021 to underline the reduction in fuel consumption with postoperative telehealth application (pre-COVID-19 vs. COVID-19). A propensity score matching was implemented to optimize comparability. Results: From 276 BCP patients, PSM included 69 pre-COVID-19 and 69 COVID-19 groups, respectively. No statistically significant difference was found in the tumor stage, marital status, and distance from the hospital. A total of 466 postoperative visits was performed and a statistically significant difference in telehealth visit rate was found between groups (1.75% vs. 51.68%; p<0.001). A reduction of 4312.38 km in travel to the hospital was found in the COVID-19 group. No difference was found in postoperative complications. Conclusions: Health systems worldwide are implementing zero-carbon programs to reduce their carbon footprint. Breast surgeons should consider the consequences of their actions and embrace the pillars of the circular economy. Our data could promote further action in order to raise awareness regarding carbon footprint of breast surgery

Delay in breast cancer treatments during the first COVID-19 lockdown. a multicentric analysis of 432 patients

Background/Aim: Extraordinary restrictions aimed to limit Sars-CoV-2 spreading; they imposed a total reorganization of the health-system. Oncological treatments experienced a significant slowdown. The aim of our multicentric retrospective study was to evaluate screening suspension and surgical treatment delay during COVID-19 and the impact on breast cancer presentation. Patients and Methods: All patients who underwent breast surgery from March 11, 2020 to May 30, 2020 were evaluated and considered as the Lockdown group. These patients were compared with similar patients of the previous year, the Pre-Lockdown group. Results: A total of 432 patients were evaluated; n=223 and n=209 in the Lockdown

The Effect of coronavirus (COVID-19) on breast cancer teamwork: A multicentric survey

Background/Aim: Despite the large amount of clinical data available of Coronavirus-19 (COVID-19), not many studies have been conducted about the psychological toll on Health Care Workers (HCWs). Patients and Methods: In this multicentric descriptive study, surveys were distributed among 4 different Breast Cancer Centers (BCC). BCCs were distinguished according to COVID-19 tertiary care hospital (COVID/No-COVID) and district prevalence (DP) (High vs. Low). DASS-21 score, PSS score and demographic data (age, sex, work) were evaluated. Results: A total of 51 HCWs were analyzed in the study. Age, work and sex did not demonstrate statistically significant values. Statistically significant distribution was found between DASS-21-stress score and COVID/No-COVID (p=0.043). No difference was found in the remaining DASS-21 and PSS scores, dividing the HCWs according to COVID-19-hospital and DP. Conclusion: Working in a COVID-19-hospital represents a factor that negatively affects psychosocial wellbeing. However, DP seems not to affect the psychosocial well-being of BCC HCWs. During the outbreak, psychological support for low risk HCWs should be provided regardless DP

Fine Particulate air Pollution is Associated with Higher Vulnerability to Atrial Fibrillation—The APACR Study

The acute effects and the time course of fine particulate pollution (PM2.5) on atrial fibrillation/flutter (AF) predictors, including P-wave duration, PR interval duration, and P-wave complexity, were investigated in a community-dwelling sample of 106 nonsmokers. Individual-level 24-h beat-to-beat electrocardiogram (ECG) data were visually examined. After identifying and removing artifacts and arrhythmic beats, the 30-min averages of the AF predictors were calculated. A personal PM2.5 monitor was used to measure individual-level, real-time PM2.5 exposures during the same 24-h period, and corresponding 30-min average PM2.5 concentration were calculated. Under a linear mixed-effects modeling framework, distributed lag models were used to estimate regression coefficients (βs) associating PM2.5 with AF predictors. Most of the adverse effects on AF predictors occurred within 1.5–2 h after PM2.5 exposure. The multivariable adjusted βs per 10-µg/m3 rise in PM2.5 at lag 1 and lag 2 were significantly associated with P-wave complexity. PM2.5 exposure was also significantly associated with prolonged PR duration at lag 3 and lag 4. Higher PM2.5 was found to be associated with increases in P-wave complexity and PR duration. Maximal effects were observed within 2 h. These findings suggest that PM2.5 adversely affects AF predictors; thus, PM2.5 may be indicative of greater susceptibility to AF

Global disparities in surgeons’ workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study

: The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSS® v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity &gt; 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI
