Background: Although FD may affect up to 10% of the general population, the therapy for FD is not standard. Recently, ginger-based food supplements have been proposed in order to restore FD symptoms. Our aim was to assess the efficacy of a new nutraceutical formulation containing extract of gingerol and thymus as a possible natural treatment in managing the symptoms of functional dyspepsia (FD). Methods: We retrospectively analyzed the efficacy and safety profiles of a nutraceutical formulation containing Zingiber officinalis root extract and a standardized Thymus extract. It was administered as 1 ml/day twice a day for 90 days. Patients were assessed at baseline and after 1, 2 and 3 months of treatment, following a month of pharmacological washout by completing a questionnaire reporting the trend of the following symptoms: epigastric pain, epigastric heaviness, early satiety, belching, and regurgitation. Every symptom was assessed by a Visual Analogic Scale (VAS), ranging from 0= absence to 10= maximal severity. Results: We enrolled 272 patients (99 males and 173 females; median IQR age 49.5, 36-64 yrs). Obesity (BMI>30) was present in 28 (12.5%) patients; smokers were 83 (30.5%); and comorbidities were present in 107 (39.3%) patients. Improvement of symptom scores during treatment and one month after its suspension was extremely significant (p Conclusion: This large study found that nutraceutical formulation could be one of the tools for an empirical approach to treat patients with FD, especially when a non-conventional drug treatment is preferable for the patient and considered suitable by the physician.

BPH could be considered the most common benign tumor for men between 60 and 75 years of age. PSA is an unsatisfactory biomarker to define BPH progression to cancer. Recently, sigma-2 receptors have been recognized in several prostate cancer cell lines such as PC-3, DU-145 and LNCaP. It is reported that, in some cases, BPH could progress to malignancy and this progression can not easily be monitored by biomarkers such as PSA. In this paper we investigated 10 specimens from TURP, finding overexpression of sigma-2 receptors in two of these specimens (specimen 1 and 2) accompanied by 4 ng/mL PSA values. We hypothesize that the presence of sigma-2 receptors is related to a BPH progressing in prostate cancer. A possible correlation between sigma-2 receptors and PSA values could be useful to identify this pathological progression.

Sigma 2 (σ 2 ) receptor proteins are overexpressed in several tissues and tumour cell lines. Although the biomolecular mechanism of this overexpression must be elucidated, σ 2 receptor was considered a potential biomarker for monitoring solid tumour proliferation. In this study, we verified first σ 2 receptor overexpression by saturation analysis with radioligand in six human bladder cancer specimens, then if a possible correlation could be established between σ 2 overexpression and tumour tissue stage and grade. The results displayed that σ 2 receptor protein was normally expressed in human bladder and overexpressed in the case of high-grade transitional cell carcinomas. Moreover, these receptors were undetected in a low-grade squamous cell carcinoma and in a very rare form of anaplastic, large cells plasmacytoid cancer.
