This prospective randomized multicentered clinical study aims at implementing early diagnosis of lung cancer in high-risk heavy smokers in the Italian population. The main goal of the study is to develop a nationwide lung cancer prevention screening with high quality standard, similar to that of other screening programs i.e. breast, colon and cervix ongoing in Italy.
The Italian Pulmonary Screening Network (RISP) includes 18 centers, which will promote primary prevention by offering a smoking cessation program (i.e. counselling and anti-smoking cytisine-based therapy) and secondary prevention by screening volunteers with chest Low Dose Computed Tomography (LDCT). The primary objective of the study is to demonstrate the non-inferiority of a risk-based screening strategy (less intensive, every 2 years) compared to the standard annual screening, in terms of stage I/II lung cancer incidence.
Furthermore, the study aims to provide evidence whether blood biomarkers screening intervals can improve the efficiency of lung cancer screening by requiring less CT examinations while retaining the ability to diagnose lung cancer at curative state.

The study goal of RELApSE is to evaluate the relationships between radiological data and patients reported outcome. Restoration of Sagittal alignment and Pelvic Index (PI)-Lumbar Lordosis (LL) mismatch is closely associated with a better outcome in spinal deformities, while there is still a lack of consistent evidence regarding short-segment arthrodesis for lumbar degenerative pathology.
Over the past 10 years, an increasing number of publications reported associations between the presence of PI-LL mismatch, reduced lumbar lordosis, increased pelvic tilt, and outcome of lumbar arthrodesis for degenerative lumbar disease. Other authors, on the other hand, reported an absence of correlation between the same parameters and clinical outcome. In addition, several authors have been reported evidence regarding association of adjacent level disc degeneration and elevated pelvic tilt, persistent PI-LL mismatch and altered LL4-S1/LL ratio. Also on this aspect, other studies identify different elements as predisposing factors for junctional pathology. The definitive value for lumbar degenerative pathology of these aspects in relation to the surgical outcome remains to be clarified without consolidated evidence. The RELApSE study is the first prospective and multicenter study on these topics.
Starting from a very heterogeneous population in terms of clinical conditions, pathology and surgical treatment options, the study methods is to make the population homogeneous on some data available in all patients end that can be analyzed independently. These data are: pelvic parameters (pelvic incidence, pelvic tilt, sacral slope), segmental lumbar lordosis (LS), global lumbar lordosis (LL), PI-LL mismatch and L4-S1/LL lordosis ratio; clinical results based on administered questionnaires (Oswestry disability index, Short Form-12) and overall outcome assessment at FU (6 point scale: excellent (completely resolved symptoms), good (good clinical improvement, minor symptoms), fair (improvement compared to preoperative but still with relevant symptoms), unchanged (symptoms similar to preoperative), negative (worsening of symptoms compared to preoperative); severely worsened (reduction of personal autonomy compared to preoperative due to neurological deficits); occurrence of symptomatic junctional pathology (yes / no), need for surgical revision of the operated level (yes / no) or of the adjacent level (yes / no).No interference is foreseen on the patient's diagnostic-therapeutic path or technical treatment options chosen by partecipating surgeons. Furthermore, no form of experimentation with techniques or materials is envisaged. Data collection is prospective in the context of normal clinical activity.

Multicentric registry study in order to define outcome, predictors, treatment effects and their modifiers in poor grade aneurysmal subarachnoid haemorrhage patients.
The search for outcome predictors is going to be subdivided into three main research areas:
outcome predictors in the emergency department (so called "early brain injury phase").
outcome predictors in the neurocritical care unit (so called "delayed brain injury phase").
Treatment strategies. Two other areas of research are identified: delayed cerebral ischemia (incidence, treatment, predictors, impact on outcome) and long term follow-up (recent evidences suggest that there may be a non-negligible proportion of poor grade subarachnoid hemorrhage patients who may benefit from substantial improvement at long-term (after 6-12 months of follow-up).
