Cyanidin reduces preadipocyte differentiation and relative ChREBP expression.

Adipogenesis is a continuous process even in adult adipose tissue for the presence of preadipocytes that, when subjected to appropriate stimuli can proliferate and differentiate. ChREBP, the essential transcription factor for lipogenesis, is expressed in all tissues, but mainly in lipogenic organs. In this study, we focused on ChREBP expression during preadipocytes differentiation. Since it was found that cyanidin-3 reduces body weight in mice even in the presence of a high-fat diet, by decreasing levels of blood glucose and by improving insulin sensitivity, we studied the effect of this substance on adipogenic differentiation. For this purpose we used preadipocytes obtained from subcutaneous and visceral human adipose explant tissue, characterized and stimulated to differentiate in selective media. On cytofluorimetric analysis these cells showed mesenchymal markers (CD29, CD90, CD44), whereas they were negative for hematopoietic markers (CD45, CD10, CD117,CD31). ChREBP expression levels were quantified by immunoelectron-microscopy and western blotting analysis. In this report we show that ChREBP is expressed in preadipocytes (both nuclear and cytoplasmic compartments); the cytoplasmic level of ChREBP increased by 50 percent on day seven of differentiation into mature adipocytes. Cyanidin reduced differentiation by 20 percent (as evaluated by red oil O staining) and the expression of ChREBP. In addition, cyanidin-treated cells showed abnormal morphology, a square shape with irregular size, probably due to the fact that cyanidin may interfere with the extracellular matrix. These findings suggest that dietary cyanidin, may have inhibitory effects on adipogenesis.

Pycnogenol® Supplementation Prevents Recurrent Urinary Tract Infections/Inflammation and Interstitial Cystitis.

This open pilot registry study aimed to evaluate and compare the prophylactic effects of Pycnogenol® or cranberry extract in subjects with previous, recurrent urinary tract infections (UTI) or interstitial cystitis (IC). Methods. Inclusion criteria were recurrent UTI or IC. One subject group was supplemented with 150 mg/day Pycnogenol®, another with 400 mg/day cranberry extract, and a group served as a control in a 2-month open follow-up. Results. 64 subjects with recurrent UTI/IC completed the study. The 3 groups of subjects were comparable at baseline. All subjects had significant symptoms (minor pain, stranguria, repeated need for urination, and lower, anterior abdominal pain) at inclusion. In the course of the study, the subjects reported no tolerability problems or side effects. The incidence of UTI symptoms, in comparison with the period before inclusion in the standard management (SM) group, decreased significantly; there was a more pronounced decrease in the rate of recurrent infections in the Pycnogenol® group (p < 0.05). The improvement in patients supplemented with Pycnogenol® was significantly superior to the effects of cranberry. At the end of the study, all subjects in the Pycnogenol® group were infection-free (p < 0.05vs. cranberry). Significantly, more subjects were completely symptom-free after 2 months of management with Pycnogenol® (20/22) than with SM (18/22) and cranberry (16/20). Conclusions. This pilot registry suggests that 60 days of Pycnogenol® supplementation possibly decrease the occurrence of UTIs and IC without side effects and with an efficacy superior to cranberry.

Interaction study between antiplatelet agents, anticoagulants, thyroid replacement therapy and a bioavailable formulation of curcumin (Meriva®).

OBJECTIVE: The objective of this clinical study is to evaluate possible interactions between antiplatelet agents, anticoagulants, thyroid hormone replacement therapy and a formulation of curcumin (Meriva®) that resulted effective for the complementary treatment of osteoarthritis. PATIENTS AND METHODS: Interaction between antiplatelet agents and Meriva® was evaluated by measuring anti-platelet activity with the in-vivo bleeding-time (BT) in patients assuming acetylsalicylic acid or ticlopidine or clopidogrel from at least 2 years. The BT was evaluated before and after 10 days of supplementation with Meriva®. The interaction between anticoagulants and Meriva® was evaluated in patients using warfarin or dabigatran for previous venous thrombosis. The INR level was evaluated before and after 10 days of supplementation with the curcumin formulation. Thyroid function tests in hypothyroid patients using LT4 replacement therapy (Eutirox®) were evaluated before and after 15 days of supplementation with Meriva®. Similarly, levels of glycemia and glycated hemoglobin were evaluated in diabetic patients in treatment with metformin, before and after 10 days of supplementation with the studied product. RESULTS: After 10 days of supplementation with Meriva® the average BT value was not significantly different for patients assuming acetylsalicylic acid, ticlopidine or clopidogrel at standard dosages. Similarly, after 10 days of Meriva® treatment, the INR level in the two groups of patients assuming warfarin or dabigatran was not statistically different from that observed at baseline. In the analyzed patients assuming LT4 or metformin, no interactions between the therapy and Meriva® were observed. CONCLUSIONS: Results from this non-interaction clinical study suggest that Meriva® does not interfere with the antiplatelet activity of the most common antiplatelet agents nor alters the INR values in stable patients assuming warfarin or dabigatran. Similarly, dosages of LT4 or metformin do not need to be adjusted in case of complementary treatment with Meriva®.

Laparoscopic colectomy in colon cancer. A single-center clinical experience.

INTRODUCTION: Aim of our study was to compare the results of the laparoscopic technique to those obtained by traditional open approach in patients with colon cancer. The advantages, disadvantages, and the contraindications (real and presumptive) of this mini-invasive approach are described, by comparing the data obtained from the international literature with our clinical experience. PATIENTS AND METHODS: From February 2000 to May 2006, we performed 73 laparoscopic colectomies for cancer in the Operative Unit of General and Laparoscopic Surgery, Department of Surgical Sciences of the University of Chieti, Italy. The data of these patients were compared with the data obtained from 141 other patients who underwent open procedure for the same pathology in the same period and in the same Unit. Factors such as obesity, previous major abdominal surgery, T4 cancers, perforation and obstruction of the colon, tumor located in the transverse colon or in the left flexure of the colon were considered contraindications to laparoscopic approach. RESULTS: The length of surgical specimens and the number of lymph nodes removed did not show significant differences in the two groups. Two patients in the open procedure group died in the postoperative period. No postoperative death was noted in the group of patients operated by laparoscopic method. Postoperative complications requiring re-operation were observed in 9 patients in the open group and in 3 patients of laparoscopic group. Postoperative complications not requiring re-operation were observed in 16 patients in the open group and in 4 patients in laparoscopic group. Hospital stay was shorter for laparoscopic right or left colectomy compared to corresponding open procedures. At the follow-up (a mean 30 months), the overall survival was 78% for open colectomies and 82.1% for laparoscopic colectomies. Disease-free survival, excluding patients with stage IV tumor and patients died in the postoperative period, was 77.6% for open colectomies and 82.5% for laparoscopic colectomies. In the group of laparoscopic patients, we observed 1 case of port-site recurrence. CONCLUSIONS: Our clinical experience, even if limited by the number of patients and by the duration of follow-up period, contributes in confirming the reliability of laparoscopic procedures in the treatment of tumours of the colon and the safety of oncological results.

A natural pharma standard supplement formulation to control treatment-related toxicity and oxidative stress in genitourinary cancer: a preliminary study.

OBJECTIVE: Oncological treatments are associated with toxicities that may decrease compliance to treatment in most genitourinary cancer patients. Supplementation with pharmaceutical-standardized supplement may be a supplementary method to control the side effects after chemo- and radiotherapy and the increased oxidative stress associated to treatments. This registry study evaluated a natural combination of supplements containing curcumin, cordyceps, and astaxanthin (Oncotris™) used as supplementary management in genitourinary cancer patients who had undergone oncological therapy. PATIENTS AND METHODS: Patients with genitourinary cancers (prostate or bladder malignancies) who had undergone and completed cancer treatments (radiotherapy, chemotherapy or intravesical immunotherapy with increased oxidative stress and residual symptoms) were recruited in this registry, supplement study. Registry subjects (n = 61) freely decided to follow either a standard management (SM) (control group = 35) or SM plus oral daily supplementation (supplement group = 26). Evaluation of severity of treatment-related residual side effects, blood count test, prostate-specific antigen (PSA) test and plasma free radicals (oxidative stress) were performed at inclusion and at the end of the observational period (6 weeks). RESULTS: Two patients dropped out during the registry. Therefore, the analysis included 59 participants: 26 individuals in the supplementation group and 33 in the control group. In the supplement group, the intensity of signs and symptoms (treatment-related) and residual side effects significantly decreased at 6 weeks: minimal changes were observed in controls. Supplementation with Oncotris™ was associated with a significant improvement in blood cell count and with a decreased level of plasmatic PSA and oxidative stress. CONCLUSIONS: Naturally-derived supplements, specifically Oncotris™ (patent pending), could support the body to overcome the treatment-related toxicities - and the relative oxidative stress in cancer patients.

Management of Varicose Veins and Chronic Venous Insufficiency in a Comparative Registry with Nine Venoactive Products in Comparison with Stockings.

The aim of this registry study was to compare products used to control symptoms of CVI. Endpoints of the study were microcirculation, effects on volume changes, and symptoms (analogue scale). Pycnogenol, venoruton, troxerutin, the complex diosmin-hesperidin, Antistax, Mirtoselect (bilberry), escin, and the combination Venoruton-Pycnogenol (VE-PY) were compared with compressions. No safety or tolerability problems were observed. At inclusion, measurements in the groups were comparable: 1,051 patients completed the registry. Best performers : Venoruton, Pycnogenol, and the combination VE-PY produced the best effects on skin flux. These products and the combination VE-PY better improved PO 2 and PCO 2 . The edema score was decreased more effectively with the combination and with Pycnogenol. Venoruton; Antistax also had good results. Considering volumetry, the best performers were the combination PY-VE and the two single products Venoruton and Pycnogenol. Antistax results for edema were also good. The best improvement in symptoms score were obtained with Pycnogenol and compression. A larger decrease in oxidative stress was observed with Pycnogenol, Venoruton, and with the VE-PY combination. Good effects of Antistax were also observed. Parestesias were lower with Pycnogenol and with Antistax. Considering the need for interventions, the best performers were Pycnogenol, VE-PY, and compression. The efficacy of Pycnogenol and the combination are competitive with stockings that do not have the same tolerability in warmer climates. A larger and more prolonged evaluation is suggested to evaluate cost-efficacy (and non-interference with drugs) of these products in the management of CVI. The registry is in progress; other products are in evaluation.

Movardol® (N-acetylglucosamine, Boswellia serrata, ginger) supplementation in the management of knee osteoarthritis: preliminary results from a 6-month registry study.

OBJECTIVE: Knee Osteoarthritis (OA) is a chronic disease caused by the deterioration of cartilage in joints, which results in activation of the inflammatory response, pain, and impaired movement. Complementary therapies, particularly supplementation, in the management of moderate/severe knee OA have been gaining attention. This registry study aimed at evaluating the synergistic effect of Movardol®, a supplementation containing active ingredients with recognized anti-inflammatory activities on symptoms and levels of circulating biomarkers of knee OA. PATIENTS AND METHODS: 54 subjects with symptomatic, moderate knee OA freely decided to follow either a standard management (SM) (n = 26) or SM plus oral supplementation with Movardol® (n = 28). Movardol® supplementation containing N-acetyl-D-glucosamine, ginger, and Boswellia Serrata extract was taken at the following dosage: 3 tablets/day for one week and then 2 tablets/day. Several parameters were assessed at inclusion and after 1, 3 and 6 months: functional impairment by the Karnofsky Performance Scale Index; pain, stiffness, physical, social and emotional functions by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC); total and pain-free walking distance; circulating biomarkers of inflammation and oxidative stress. RESULTS: Significant improvements in the functional outcomes and pain-free walking distance were observed after 1, 3 and 6 months in OA patients supplemented with Movardol®. Moreover, all the signs/symptoms of disease assessed by the WOMAC tended to regress over a 6-month period in patients following SM+supplementation. Inflammatory markers and plasmatic content of reactive oxygen species decreased over 6 months, in supplemented patients. Movardol® supplementation resulted to be safe and well tolerated, also showing the beneficial effect in term of a decrease in pharmacological and non-pharmacological treatments and, consequently, reduction in management costs. CONCLUSIONS: These preliminary results indicate the efficacy and safety of Movardol® supplementation in the management of moderate knee OA.

Management of functional, hepatic damage after chemotherapy with Liverubin (pharma-standard silymarin).

Mild, temporary hepatic failure (MTHF) after chemotherapy is a common clinical problem; in case of repeated episodes MTHF may cause chronic impairment. This registry has evaluated post- chemotherapy (PC)-MTHF in subjects using Liverubin (standardized Silymarin) for 8 weeks (3 capsules/day). METHODS: PC-MTHF was evaluated in a registry study. Hepatitis markers were negative at inclusion and at end-registry. In the final registry there were results concerning 18 Liverubin-supplemented patients and 19 controls completing the 8-week period. Signs/symptoms. The distribution of the most common symptoms and signs with ultrasound scans were comparable. Symptoms were mostly minimal or subclinical. Most symptoms observed at inclusion were completely disappeared or greatly attenuated after 8 weeks. The improvement produced by Liverubin induced a better and faster disappearance of symptoms. The results of the blood tests (at inclusion and at 8 weeks showed the increase in albumin, significantly (P<0.05) faster with the final values higher in the supplement group. Total bilirubin was reduced with the supplement better than in controls (P<0.05). Direct bilirubin values improved more in the supplement (P<0.05) group. The decrease in SGPT and AST-ASAT was more evident with the supplement (P<0.05). Improvement in controls was more limited. Alkaline phosphatase was significantly lower (than in controls) with Liverubin at 8 weeks (p<0.05). Gamma GT also decreased more and faster with the supplement. The ESR (erythrocytes sedimentation rate) was decreased in both groups, more in the Liverubin group (P<0.05). There was a more limited decrease in controls with persisting higher values at 8 weeks. The white cell count was also better at 3 months (with a larger decrease with the supplement; P<0.05). Oxidative stress. Plasma free radicals (PFR) were elevated in both groups at inclusion. A more significant decrease in the supplement group was observed at 8 weeks. Persisting elevation in values was seen in controls (P<0.05). Platelets values improved better with Liverubin (P<0.05). Safety and tolerability were optimal (no side effect was registered). In conclusion, results from this pilot registry indicate a significant activity of Liverubin associated with a very good safety profile, in patients with post-chemotherapy hepatic failure. The recovery of hepatic function is faster and more effective with Liverubin in comparison with the best "standard" management.

Supplementary management of functional, hepatic damage with Liverubin (pharma-standard Silymarin). A 3-month registry.

Mild, temporary hepatic failure (MTHF) is a common clinical problem; in case of repeated episodes MTHF may cause chronic liver impairment. This registry has evaluated MTHF in subjects using Liverubin (standardized Silymarin) for 8 weeks. METHODS: MTHF was evaluated in a registry study. In all subjects viral hepatitis markers were negative at inclusion. Different possible causes of MTHF had been considered. In these subjects alcohol was not a main factor. The registry included MTHF patients with decreased albumin levels, increased total bilirubin, altered hepatic function enzymes, increased oxidative stress. Two management groups were created: a standard management (SM) group and a SM+Liverubin group; 32 Liverubin patients and 33 SM subjects completed the registry. Liverubin was used at the dosage of two tablets (each equivalent to 140 mg) daily. RESULTS: Distribution of symptoms, blood test values and ultrasound results were comparable. Symptoms observed at inclusion disappeared at 3 months in both groups. The increase in albumin levels was significantly (P<0.05 at 4 weeks) faster and the final blood tests improved more with Liverubin. Total bilirubin was reduced with the supplement (better than in controls; P<0.05). Direct bilirubin values improved more in the supplement group at 3 months (P<0.05). The decrease of SGPT and AST- ASAT was more evident in the supplement group (P<0.05). Alkaline phosphatase value was normalized at in Liverubin patients; values decreased less in controls (P<0.05). Gamma GT decreased more with Liverubin. ESR was decreased in both groups (significantly more with Liverubin: P<0.05). There was a less important decrease in controls at 3 months. The white cell count was also better with the supplement group; P<0.05). Plasma free radicals - significantly elevated in both groups at inclusion - decreased more with the supplement at 3 months. All other blood tests (including hematocrit, renal function tests) were within the normal range at inclusion and at 3 months in both groups. Hepatitis markers were negative at inclusion and at end-registry. Safety and tolerability were optimal (no side effect was registered). CONCLUSION: In conclusion, data from this pilot, registry study indicate a significant activity of Liverubin associated with a very good safety profile, in patients with temporary hepatic failure. The recovery of hepatic function is faster and more effective with Liverubin compared to the best "standard" management.

The value of segmental pressure measurement in the assessment of peripheral vascular disease.

In 60 patients with symptomatic peripheral vascular disease a study was performed to evaluate the reliability of segmental pressure measurement in detecting and localizing vascular lesions. Five groups of limbs with different pressure patterns were identified: normals, distals disease (diabetics), aorto-iliac disease, aorto-iliac and superficial femoral disease, superficial femoral and distal disease. The comparison with angiography showed the high efficacy of this method (when combined with Doppler study of the arteries) to localize and quantify the lesions. The combination with femoral intraarterial pressure measurement allows to predict exactly the segmental pressure after segmental vascular reconstructions. It is concluded that segmental pressure measurement (with the described technique) selects patients for angiography and surgery and can predict the outcome of vascular reconstruction.

[9 years of electric stimulation in Abruzzo. cognitive findings]. / 9 anni di elettrostimolazione in Abruzzo. Indagine conoscitiva.

Data relating to 9 years of definitive electrostimulation in the Abruzzo region are presented. An account is given of the epidemiology, the indications for implantation, the stimulation and control technology, and the complications. It is pointed out that the implantability index rose from 1976 to 1978 to reach values of 130.5 implants/mil/inhab. This is in comparable with that in the literature. The technologies and modalities are rapidly developing, and a definitive picture cannot be drawn as yet. Further cognitive investigations are envisaged.

[Prognostic factors in gastric carcinoma]. / Fattori prognostici del carcinoma gastrico.

A personal experiment conducted on 80 gastric carcinoma patients requiring radical surgery at the Special Surgical Pathology Institute is reported. The aim of the study was to identify and assess the factors capable of influencing prognosis e.g. sex, age, TNM, type of operation, symptoms etc and to make a comparison with data from the international literature.

[Diagnosis of thyroid nodules]. / Sulla diagnostica del nodulo tiroideo.

The basic features of the most common endocrine pathology, the thyroid nodule are analysed. After a brief assessment of the incidence of the condition the problem of clinical and instrumental diagnosis is tackled with the aim of demonstrating the value and possibility of sub-clinical diagnosis of micronodules. The present work aims to identify the fastest, most efficient and cheapest diagnostic procedure.

[Autonomous adenoma of the thyroid]. / L'adenoma autonomo della tiroide.

Toxic goitre often referred to in the literature as "autonomous" adenoma or nodule actually signifies a number of different pathologies that are characterised by autonomy and hyperfunction so that it is now thought more appropriate to call it an autonomous follicle. Clinical features and the hormone profile suggest the diagnosis which is confirmed by scintiscan with curve as well as dynamic inhibition and stimulation tests using TRH, procedures that reveal both latent hyperfunction and autonomy. The most common current therapeutic approach is surgical since this provides a complete cure while leaving the surrounding thyroid tissue undisturbed.

[Diagnosis of cerebrovascular diseases. International multicentric study]. / Diagnosi delle malattie cerebrovascolari. Studio policentrico internazionale.

A Polycentric International Study was performed to evaluate the diagnostic methods in patients with cerebrovascular diseases. New tools and new non-invasive methods were proposed by the 15 centers collaborating in this study. The difficulty of defining a standard method to investigate not invasively and invasively these patients still remains.

[Breast cancer. Epidemiology and other factors related to incidence in various populations]. / Carcinoma della mammella. Epidemiologia ed altri fattori connessi alla incidenza in varie popolazioni.

An extensive review of epidemiology, etiology, age, genetic factors, race, alimentary habits and hormonal patterns have been analysed in studies concerning patients with breast cancer. The role of other factors (the age of menopause, the geographic distribution, the action of reserpine and many possible causes) are also discussed. The evidences observed in many studies performed in the last years in different countries are compared but definitive data cannot be reached. The material reported in these studies is not homogeneous and this review can only indicate the problems still present in this field and the subjects we need to investigate in the next years.

[Current diagnosis of venous diseases of the lower limbs]. / Diagnostica attuale della patologia venosa degli arti inferiori.

The haemodynamic of venous circulation of lower limbs seems to be not yet fully understood and different methods are available to study clinical patterns of venous insufficiency, deep venous incompetence or venous occlusion. Simple and common methods as venography, venous doppler and plethysmography are frequently used but other method as impedance plethysmography, ambulatory venous pressure, photoplethysmography, isotopes and thermography can be used for research or clinical investigation. The techniques and the indications of these tests are reviewed and critically analyzed to evaluate the best approach to the patients with venous pathology.

Diabetes and surgery.

Diabetes mellitus is the metabolic disorder most commonly met by the surgeon. Hyperglycemia, hypoglycemia, electrolyte imbalance, vascular, renal and neurological complications and liability to infections must always kept in mind. An accurate preoperative evaluation is essential. The patient must be carefully controlled during the operation and in early postoperative period by i.v. glucose solution with i.v. or subcutaneous insulin. Schemes of treatment for diabetic surgical patients are proposed and results by a sample of 100 patients undergoing major surgical procedures are reported and discussed. Under adequate treatment incidence of complications in these patients is almost the same of not-diabetic patients. Continuous intravenous infusion of 10% glucose solution (500 ml every 6 hours) with potassium and insulin seems to be very safe if continuous monitoring of the blood and urine glucose and ketones is observed.

Encapsulated liquid crystal (ELC) thermography in peripheral arterial disease.

The correlation between peripheral pressures and skin temperatures was studied by encapsulated liquid crystal (ELC) plates in 66 patients with peripheral arterial disease. The study was also performed to evaluate the correlation between symptoms and temperature in four symptomatic groups of patients (with claudication, rest pain, ischemic ulcerations or gangrene and chronic ulcerations in diabetic patients). The correlation with temperature and pressure was positive (0.99) and so it was that one between symptoms and temperature. This method may be easily used in patients with peripheral arterial disease to evaluate the perfusion of the extremities and to compare bordering areas. Considering these data different new applications of this technique in peripheral vascular disease diagnosis can be suggested. The elevate velocity of the method (about 5 seconds) reveal also very fast variations of the perfusion and this may be useful to study functional decreases of blood pressure.

[Carcinoma with a branchial origin]. / Il carcinoma ad origine branchiale.

Carcinoma was observed in a patient with a branchial cyst of about 40 years' standing. The neoformation was removed, but the patient died as a result of cardiocirculatory complications a little more than a year later. Note is taken of the rarity of this form and the compliance of the reported case with the criteria laid down by Martin et al. in 1950.
