Dalla libertà alla "servitù dorata". Rodi nella Storia dei Romani di Gaetano De Sanctis
No full textIn volume Iv of his masterpiece History of the romans (published in 1923), gaetano De sanctis analyses the history of rhodes in the first thirty years of the 2nd century Bce, against the background of rome’s expansion into the eastern mediterranean. this chapter argues that some aspects of De sanctis’s historical reflections on this topic are also found in his contempo- rary articles; others, by contrast, anticipate the main themes he and his pupils will focus on in later years, i.e. “freedom” and “empire”
Grand challenges in colorectal and proctological surgery
No full textColorectal surgery (CRS) and proctology represent a branch of general surgery that is becoming increasingly important and relevant. In recent decades, there have been so many innovations that have given coloproctological surgery an identity of its own. In recent years, innovations in major CRS have been revolutionizing healthcare and improving patient outcomes ranging from early diagnosis to the most modern treatment options
Spatial solitons in X(2) planar photonic crystals
No full textWe analyze light self-confinement induced by multiple nonlinear resonances in a two-dimensional X(2) photonic crystal. With reference to second-harmonic generation in a hexagonal lattice, we show that the system can not only support two-color (1+1)D solitary waves with enhanced confinement and steering capabilities but also enable novel features such as wavelength-dependent soliton routing
Evaluation of clinical examination and preoperative imaging in patients with right iliac fossa pain and a medium or high risk score for appendicitis (RIFT-2)
No full textIntroduction: Clinical risk models can be used to identify UK patients with right iliac fosa
pain who are at low-risk of appendicitis and can be safely managed on ambulatory pathways,
avoiding hospital admission and unnecessary surgery. This study examined the diagnostic
pathways in patients with medium or high-risk scores.
Methods: This prospective cohort study included patients admitted with suspected
appendicitis in the UK. Patients aged ≥16 years were included if they had a medium or
high-risk score for appendicitis (Appendicitis Inflammatory Response Score (AIRS) >2 in
men, Adult Appendicitis Score (AAS) >8 in women). The primary outcome measure was
the normal appendicectomy rate (NAR). The AIRS and AAS risk prediction models were
validated against pre-determined criteria.
Results: This UK study included 2,231 women and 1,958 men. Overall, 57.7% of patients
underwent surgery. The NAR was 18.4% in women aged 16-45 years, 9.5% in men aged 16-
45 years, 4.5% in women aged ≥46 years, and 2.1% in men aged ≥46 years. Risk prediction
models did not achieve the pre-determined threshold to be used to identify patients with
appendicitis. Ultrasound was the most common imaging modality in women aged 16-45
years, whereas CT was most common in the other subgroups. CT was performed in 12.8%
of women aged 16-45 years, 21.1% in men aged 16-45 years, 69.3% in women aged ≥46
years, and 74.5% in men aged ≥46 years. The overall NAR in patients who had CT imaging
alone (3.6%) was lower than in patients who had no imaging (12.4%) or ultrasound imaging
alone (19.0%).
Conclusion: UK patients with a low-risk of appendicitis should be triaged to ambulatory
management, whilst those with a medium/high-risk should mostly undergo a CT scan.
Normal appendicectomy should become a specific therapeutic option rather than a chance

Outcomes after perioperative SARS-CoV-2 infection in patients with proximal femoral fractures: an international cohort study
No full textObjectives Studies have demonstrated high rates of mortality in people with proximal femoral fracture and SARS-CoV-2, but there is limited published data on the factors that influence mortality for clinicians to make informed treatment decisions. This study aims to report the 30-day mortality associated with perioperative infection of patients undergoing surgery for proximal femoral fractures and to examine the factors that influence mortality in a multivariate analysis.Setting Prospective, international, multicentre, observational cohort study.Participants Patients undergoing any operation for a proximal femoral fracture from 1 February to 30 April 2020 and with perioperative SARS-CoV-2 infection (either 7 days prior or 30-day postoperative).Primary outcome 30-day mortality. Multivariate modelling was performed to identify factors associated with 30-day mortality.Results This study reports included 1063 patients from 174 hospitals in 19 countries. Overall 30-day mortality was 29.4% (313/1063). In an adjusted model, 30-day mortality was associated with male gender (OR 2.29, 95% CI 1.68 to 3.13, p<0.001), age >80 years (OR 1.60, 95% CI 1.1 to 2.31, p=0.013), preoperative diagnosis of dementia (OR 1.57, 95% CI 1.15 to 2.16, p=0.005), kidney disease (OR 1.73, 95% CI 1.18 to 2.55, p=0.005) and congestive heart failure (OR 1.62, 95% CI 1.06 to 2.48, p=0.025). Mortality at 30 days was lower in patients with a preoperative diagnosis of SARS-CoV-2 (OR 0.6, 95% CI 0.6 (0.42 to 0.85), p=0.004). There was no difference in mortality in patients with an increase to delay in surgery (p=0.220) or type of anaesthetic given (p=0.787).Conclusions Patients undergoing surgery for a proximal femoral fracture with a perioperative infection of SARS-CoV-2 have a high rate of mortality. This study would support the need for providing these patients with individualised medical and anaesthetic care, including medical optimisation before theatre. Careful preoperative counselling is needed for those with a proximal femoral fracture and SARS-CoV-2, especially those in the highest risk groups
