Efficacia del trattamento conservativo in soggetti affetti da groin pain: una revisione sistematica della letteratura

Background: il groin pain è un dolore riferito in un’area che è delimitata medialmente dalla sinfisi pubica, superiormente dal basso addome, lateralmente dalla spina iliaca antero-superiore e inferiormente dalla porzione mediale della coscia. Una sindrome composta da patologie multiple e, per quanto sia diffusa a livello di casistica di infortunio, si tratta di una delle lesioni meno comprese e poco spiegate in chirurgia generale e ortopedia. In questo scenario, colpisce prevalentemente il giovane sportivo causando dolore e interruzione della pratica sportiva. Obiettivi: valutare l’efficacia della gestione conservativa su dolore e ritorno all’attività sportiva in pazienti con problematiche e lesioni nella zona pubico- inguinale. Materiali e metodi: la ricerca è stata condotta su due banche dati: PubMed e Cochrane Library. Non è stato impostato il filtro lingua; sono stati inclusi studi di trattamento in atleti con dolore all’inguine, studi randomizzati controllati, studi clinici controllati e serie di casi. Risultati: il trattamento conservativo si è rivelato sicuro ed efficace nella gestione del dolore all’inguine con un buon numero di atleti che è riuscito a tornare all’attività sportiva. Tuttavia secondo gli studi presi in considerazione, il trattamento chirurgico risulta più efficace in termini di tempi di recupero; per cui spesso viene utilizzato dopo il fallimento della terapia conservativa nell’atleta. Conclusioni: nella gestione dei pazienti affetti da groin pain come primo approccio si deve sempre preferire l’approccio conservativo rispetto al chirurgico, in quanto meno invasivo e comunque riporta buone evidenze scientifiche per quanto riguarda l’efficacia. Qualora questo non riportasse miglioramenti evidenti al termine di un periodo di cura di qualche settimana, si può procedere all’operazione chirurgica secondo la tecnica (chirurgica) giudicata più idonea alla situazione

COVID-19 seasonality in temperate countries

Introduction: While the beneficial effect of vaccination, restrictive measures, and social distancing in reducing mortality due to SARS-CoV-2 is intuitive and taken for granted, seasonality (predictable fluctuation or pattern that recurs or repeats over a one-year period) is still poorly understood and insufficiently taken into consideration. We aimed to examine SARS-CoV-2 seasonality in countries with temperate climate. Methods: We identified countries with temperate climate and extracted average country temperature data from the National Center for Environmental information and from the Climate Change Knowledge Portal. We obtained mortality and vaccination rates from an open access database. We used the stringency index derived from the Oxford COVID-19 Government Response Tracker to quantify restriction policies. We used Spearman's and rank-correlation non-parametric test coefficients to investigate the association between COVID-19 mortality and temperature values. We employed multivariate regression models to analyze how containment measures, vaccinations, and monthly temperatures affected COVID-19 mortality rates. Results: The time series for daily deaths per million inhabitants and average monthly temperatures of European countries and US states with a temperate climate had a negative correlation (p < 0.0001 for all countries, 0.40 < R < 0.86). When running multivariate regression models with country fixed effects, we noted that mortality rates were significantly lower when temperature were higher. Interestingly, when adding an interaction term between monthly temperatures and vaccination rates, we found that as monthly temperatures dropped, the effect of the vaccination campaign on mortality was larger than at higher temperatures. Discussion: Deaths attributed to SARS-CoV-2 decreased during the summer period in temperate countries. We found that the effect of vaccination rates on mortality was stronger when temperatures were lower. Stakeholders should consider seasonality in managing SARS-CoV-2 and future pandemics to minimize mortality, limit the pressure on hospitals and intensive care units while maintaining economic and social activities

Paraffin/water nanoemulsions with reduced supercooling for thermal management systems

Phase change material nanoemulsions were synthesised and characterised to be used as possible storage and heat transfers fluids in low temperature thermal management. Thermal energy storage densities of different paraffin / water nanoemulsions were studied, and RT44HC was selected as the optimized PCM. Seven different nucleating agents, including paraffin waxes with higher melting point, nanoparticles and other organic materials, have been experimentally tested. It was found that 5% paraffin nanoemulsions with 1-octadecanol as nucleating agent (weight fraction 1:10 with respect to PCM), reduced supercooling up to 32 % over samples without nucleating agent, while maintaining the thermal properties of the sample under thermal cycling. Good stability (for both high temperatures and thermal cycling) of the nanoemulsions were observed, while an increase in the viscosity was measured

A new device for ultrasound-guided peripheral venous access

Background: In patients with difficult peripheral venous access, alternative techniques require expertise and are invasive, expensive, and prone to serious adverse events. This brought us to designing a new venous catheter (JLB\uae Deltamed, Inc.) for the cannulation of medium and large bore veins; it is echogenic, and available in different lengths (60 / 70 / 80 mm) and Gauges (14 / 16 / 17 / 18). Methods: We led a multi-center observational convenience sampling study to evaluate safety and effectiveness of JLB. Data was collected from June 2015 to February 2018. Inclusion criteria were age \u2a7e 18, difficulty in obtaining superficial venous access in the veins of the arm, need for rapid infusion, or patient\u2019s preference. Results: We enrolled 1000 patients, mean age 66.8 years. In total, 951 (95.1%) had the device placed in internal jugular vein, 28 in basilic or cephalic vein, 15 in femoral vein, 5 in axillary vein (infra-clavicular tract), and 1 in the external jugular vein. The procedure was performed by attending physicians or emergency medicine residents under US guidance. Mean procedure time (from disinfection to securing) was approximately 240 s. Mean attempts number was 1.21. Early complications (&lt;24 h) occurred in four patients, consisting in two soft tissue hematoma, one phlebitis, and one atrial tachyarrhythmia. No major complications (such as pneumothorax) were reported. Mean indwelling time was 168 h (7 days); early occlusion/dislocation occurred in four cases. Conclusion: According to preliminary data, the application of JLB appears to be safe, cost-effective, and rapid to place bedside

Disentangling the Association of Hydroxychloroquine Treatment with Mortality in Covid-19 Hospitalized Patients through Hierarchical Clustering

The efficacy of hydroxychloroquine (HCQ) in treating SARS-CoV-2 infection is harshly debated, with observational and experimental studies reporting contrasting results. To clarify the role of HCQ in Covid-19 patients, we carried out a retrospective observational study of 4,396 unselected patients hospitalized for Covid-19 in Italy (February-May 2020). Patients' characteristics were collected at entry, including age, sex, obesity, smoking status, blood parameters, history of diabetes, cancer, cardiovascular and chronic pulmonary diseases, and medications in use. These were used to identify subtypes of patients with similar characteristics through hierarchical clustering based on Gower distance. Using multivariable Cox regressions, these clusters were then tested for association with mortality and modification of effect by treatment with HCQ. We identified two clusters, one of 3,913 younger patients with lower circulating inflammation levels and better renal function, and one of 483 generally older and more comorbid subjects, more prevalently men and smokers. The latter group was at increased death risk adjusted by HCQ (HR[CI95%] = 3.80[3.08-4.67]), while HCQ showed an independent inverse association (0.51[0.43-0.61]), as well as a significant influence of cluster*HCQ interaction (p&lt;0.001). This was driven by a differential association of HCQ with mortality between the high (0.89[0.65-1.22]) and the low risk cluster (0.46[0.39-0.54]). These effects survived adjustments for additional medications in use and were concordant with associations with disease severity and outcome. These findings suggest a particularly beneficial effect of HCQ within low risk Covid-19 patients and may contribute to clarifying the current controversy on HCQ efficacy in Covid-19 treatment

The COVID - AGICT study: COVID–19 and advanced gastro-intestinal cancer surgical treatment. A multicentric Italian study on the SARS-CoV-2 pandemic impact on gastro-intestinal cancers surgical treatment during the 2020. Analysis of perioperative and short-term oncological outcomes

Background This Italian multicentric retrospective study aimed to investigate the possible changes in outcomes of patients undergoing surgery for gastrointestinal cancers during the COVID-19 pandemic. Method Our primary endpoint was to determine whether the pandemic scenario increased the rate of patients with colorectal, gastroesophageal, and pancreatic cancers resected at an advanced stage in 2020 compared to 2019. Considering different cancer staging systems, we divided tumors into early stages and advanced stages, using pathological outcomes. Furthermore, to assess the impact of the COVID-19 pandemic on surgical outcomes, perioperative data of both 2020 and 2019 were also examined. Results Overall, a total of 8250 patients, 4370 (53%) and 3880 (47%) were surgically treated during 2019 and 2020 respectively, in 62 Italian surgical Units. In 2020, the rate of patients treated with an advanced pathological stage was not different compared to 2019 (P = 0.25). Nevertheless, the analysis of quarters revealed that in the second half of 2020 the rate of advanced cancer resected, tented to be higher compared with the same months of 2019 (P = 0.05). During the pandemic year ‘Charlson Comorbidity Index score of cancer patients (5.38 ± 2.08 vs 5.28 ± 2.22, P = 0.036), neoadjuvant treatments (23.9% vs. 19.5%, P &lt; 0.001), rate of urgent diagnosis (24.2% vs 20.3%, P &lt; 0.001), colorectal cancer urgent resection (9.4% vs. 7.37, P &lt; 0.001), and the rate of positive nodes on the total nodes resected per surgery increased significantly (7 vs 9% - 2.02 ± 4.21 vs 2.39 ± 5.23, P &lt; 0.001). Conclusions Although the SARS-CoV-2 pandemic did not influence the pathological stage of colorectal, gastroesophageal, and pancreatic cancers at the time of surgery, our study revealed that the pandemic scenario negatively impacted on several perioperative and post-operative outcomes

The MIS-COVID-AGICT Study: Trend of Minimally Invasive Surgery for Gastrointestinal Cancer Treatment During the First Waves of the COVID-19 Pandemic in Italy. Subgroup Analysis from the COVID-AGICT Study: COVID-19 and Advanced Gastrointestinal Cancer Surgical Treatment

Background: A preliminary analysis from the COVID-Advanced Gastrointestinal Cancer Surgical Treatment (AGICT) study showed that the rate of minimally invasive surgery (MIS) for elective and urgent procedures did not decrease during the pandemic year. In this article, we aimed to perform a subgroup analysis using data from the COVID-AGICT study to evaluate the trend of MIS during the COVID-19 pandemic period in Italy.Methods: This study was conducted collecting data of MIS patients from the COVID-AGICT database. The primary endpoint was to demonstrate whether the SARS-CoV-2 pandemic scenario reduced MIS for elective treatment of gastrointestinal cancer (GIC) in Italy in 2020. The secondary endpoint was to evaluate the impact of the pandemic period on perioperative outcomes in the MIS group.Results: In the pandemic year, 62% of patients underwent surgery with a minimally invasive approach, compared to 63% in 2019 (P = .23). In 2020, the proportion of patients undergoing elective MIS decreased compared to the previous year (80% versus 82%, P = .04), and the rate of urgent MIS did not differ between the 2 years (31% and 33% in 2019 and 2020 - P = .66). Colorectal cancer was less likely to be treated with MIS approach during 2020 (78% versus 75%, P &lt; .001). Conversely, the rate of MIS pancreatic resection was higher in 2020 (28% versus 22%, P &lt; .002). Conversion to an open approach was lower in 2020 (7.2% versus 9.2% - P = .01). Major postoperative complications were similar in both years (11% versus 11%, P = .9).Conclusion: In conclusion, although MIS for elective treatment of GIC in Italy was reduced during the COVID-19 pandemic period, our study revealed that the overall proportion of MIS (elective and urgent) and postoperative outcomes were comparable to the prepandemic period
