7T mMR in the assessment of acute arterial mesenteric ischemia in a rat model.

To validate a rat model of acute arterial mesenteric ischemia correlating MRI patterns with macro and microscopic changes in the small bowel. Thirty Sprague-Dawley rats were assigned to two experimental groups (Group I and Group II) of fifteen rats each. Group I underwent surgical procedure of superior mesenteric artery (SMA) ligation, followed by macroscopic observation. In Group II, a loop was tied loosely around the SMA without occluding the vessel. Three days after surgery, the loop was tied by external tips to completely occlude the artery. 7T microMR (7Tesla microMR) was performed before and 8 hours after SMA occlusion. At predetermined time-points the histopathological examinations were performed in both of groups. Macroscopic monitoring revealed thinning of mesenteric vessels, hypotonic reflex ileus and chromatic change of some loops. 7T microMR sequences evidenced loop dilation with gas-fluid mixed stasis, intraperitoneal free fluid and bowel wall hyperintensity. There were no significant differences in the histological analysis between the two groups. The gap of three days from surgery, adopted in the Group 2, allowed to avoid signs of peritoneal and mesenteric irritation which could bias imaging patterns. MR succeeded to identify the signs of arterial mesenteric ischemia.

HRCT in systemic sclerosis: correlation between respiratory functional indexes and extension of lung failure.

The purpose of the study was to identify the correlation between functional lung parameters to the extent of lung involvement evaluated by High Resolution Computed Tomography (HRCT) in systemic sclerosis (SSc), using a modified score scale. Forty-two patients with established clinical diagnosis of systemic sclerosis were retrospectively selected from the hospital information system and were prospectively included in the study protocol undergoing chest radiography, HRCT and functional lung testing. Lung involvement was assessed by HRCT, lesions were assessed in the individual segments and an additional severity score was introduced by assigning 3 points for bilateral lesions. The total new HRCT score was statistically related to severity of functional lung parameters. Thirty-six out of 42 patients showed an interstitial lung involvement by HRCT: Ground Glass (GG) n=36/42 of which n=27/36 were bilateral; IPM n=30/42, of which 24/30 were bilateral; SL n=33/42 of which 18/33 were bilateral; HC n=6/42 of which 6/6 were bilateral; SC n=6/42 of which 3/6 were bilateral.18/42 had a total score between 0-10, 6/42 between 11-20, 12/42 between 21-30, 6/42 greater than 31. Fifteen out of 42 had restrictive deficit. The results of functional respiratory testing were: FVC less than 80 percent in 12/42 patients (28.5 percent), TLC less than 80 percent in 15/42 patients (35.7 percent), DLCO less than 80 percent in 38/42 patients (90.4 percent) and DLCO/VA less than 80 percent in 21/42 patients (50 percent). The total score was statically related with FVC and TLC and with DLCO and DLCO/VA showing a significant negative correlation found between the total HRCT score of extent of lung damage and lung-function parameter (TLC: r= -0.65, P=0.00000264; FVC: r= -0.50; P=0.000575; DLCO: r= -0.74, P=2.02E-8; DLCO/VA: r= -0.68, P=0.0000005). All Pairwise Multiple Comparison Procedures showed a significant difference between the two rank sums that enclosed the comparison for DLCO/VA vs SCORE and DLCO vs SCORE. In conclusion, our modified score scale gives interesting additional data to evaluate the extension of interstitial lung involvement in SSc. It is inversely proportional to spirometry and DLCO and DLCO/VA. The bilateralism of the lesions is directly proportional to the lung damage.

Anatomical features of cephalothoracopagus variations: CT and MRI.

Conjoined twins have fascinated human mankind for a long time. Until recently, their description was limited to the dissection of non-viable cases, the description of external features and of bones by x-ray imaging. The introduction of ultrasonographic techniques gave the first in uterus images of conjoined twins, though the spatial resolution did not allow detailed descriptions. Subsequently, CT and MRI techniques allowed more precise definition of organs without any dissection, thus the need of formal interpretation of similar new images. As a matter of fact, few monstrosities have been studied by CT and MRI techniques. To this day very few cases still lack any CT/MRI documentation. Here we present a very rare type of cephalothoracopagus twins (joined at the head and the thorax). They have been accurately examined by CT and MRI imaging to study visceral structures. Pathophysiology and genetic aspects are also reviewed. These data offer precious details for accurate comprehension of imaging studies, and for theoretical studies concerning the information of several anatomical structures.

Entero-colpo-defecography vs supine entero-MRI: which one is the best tool in the differentiation of enterocele, elytrocele and edrocele?

Pelvic floor disorders represent a significant cause of morbidity associated with a severe reduction of quality of life. It represents a very common clinical problem that afflicts women three to seven time more often than men. The purpose of this study was to assess the diagnostic tools available to define the imaging strategy in patients with pelvic floor dynamic dysfunctions and to investigate their abilities in the diagnosis of enterocele, elytrocele and edrocele. From January 2008 to May 2011, 614 patients with symptoms related to pelvic floor dynamic dysfunctions were enrolled in our retrospective study. After anamnesis and clinical examination, entero-colpo-defecography (ECD) and supine entero-magnetic resonance (SE-MR) exams were performed in all patients. This study showed that the diagnostic efficacy of ECD is higher than that of SE-MR in the detection of enterocele and edrocele. Furthermore, elytrocele can be visualized only with ECD considering the position of patient during SE-MR examination. In addition, in patients planned for surgery, SE-MR is more useful to clarify the intra-pelvic interaction of multiple organ prolapse and to better define the pelvic anatomy and functioning.

Pycnogenol® supplementation improves health risk factors in subjects with metabolic syndrome.

This open, controlled study evaluated the effects of 6 month supplementation with Pycnogenol® maritime pine bark extract on health risk factors in subjects with metabolic syndrome. Pycnogenol® was used with the aim of improving risk factors associated with metabolic syndrome, central obesity, elevated triglycerides (TG), low HDL cholesterol, high blood pressure and fasting blood glucose. Sixty-four subjects (range 45-55 years) presenting with all five risk factors of metabolic syndrome were included, and Pycnogenol® was administered for 6 months. A group of 66 equivalent subjects were followed up as controls. In the 6-month study Pycnogenol® supplementation 150 mg/day decreased waist circumference, TG levels, blood pressure and increased the HDL cholesterol levels in subjects. Pycnogenol lowered fasting glucose from baseline 123 ± 8.6 mg/dl to 106.4 ± 5.3 after 3 months and to 105.3 ± 2.5 at the end of the study (p < 0.05 vs controls). Men's waist circumference decreased with Pycnogenol from 106.2 ± 2.2 cm to 98.8 ± 2.3 cm and to 98.3 ± 2.1 after 3 and 6 months. Women's waist decreased from 90.9 ± 1.6 cm to 84.6 ± 2.1 cm and to 83.6 ± 2.2 cm after 3 and 6 months. Both genders waist circumference reduction was significant as compared to controls at both time points. In addition, plasma free radicals decrease in the Pycnogenol group was more effective than in the control group (-34.6%; p < 0.05). In conclusion, this study indicates a role for Pycnogenol® for improving health risk factors in subjects with metabolic syndrome.

[Severe intermittent claudication: PGE1 treatment. A 40-week registry, efficacy and costs]. / Claudicatio intermittens severa: trattamento con PGE1. Registry, follow up (40 settimane), efficacia e costi.

AIM: Intermittent claudication (IC) in peripheral vascular disease is characterized by lower limb pain appearing on effort. Treatment with PGE1 has been successfully used to manage IC patients. This registry has evaluated safety and costs of PGE1 in the management of IC. METHODS: In this study a long-term treatment protocol (LTP), a short-term protocol (STP) and an outpatient (OP), "on-demand" treatment have been compared. A treadmill effort test has been used to evaluate walking distance. The follow up for these three protocols was 40 weeks. PGE1 treatment was associated to a risk reduction plan and to an exercise program. RESULTS: The final analysis has included 252 LTP patients, 223 STP patients and 284 OP patients (total 659 valid cases). A group of 171 comparable patients not treated with PGE1 was used for a parallel comparison. Cardiovascular mortality and morbidity has been evaluated in 731 PGE1 patients completing 24 months of follow up. All protocols have been well tolerated. No side effects were observed. The lower cost has been observed for OP patients. In the long term, mortality and morbidity were lower in patients treated with PGE1 in comparison with patients not treated with PGE1. CONCLUSION: Considering costs and results (increase in walking distance) and improvement in Karnofsky scale the STP plan appears to be better than LTP for IC patients. The OP, "on-demand" treatment offers further improvements. This last treatment plan is simpler; the plan allows better timing for exercise. The treatment can be used even in non-specialized centers.

Radiographic evaluation of mediastinal lines as a diagnostic approach to occult or subtle mediastinal abnormalities.

The mediastinal lines visible at conventional radiography represent the interfaces between the mediastinum and adjacent lung parenchyma. Preservation, obliteration, thickening and distortion of these lines represent the key to detecting and localising mediastinal abnormalities on chest radiographs. The learning objectives of this review are to: illustrate radiographic anatomy of the mediastinum with particular attention to mediastinal lines; describe radiographic signs that allow identification of mediastinal abnormalities that are difficult to detect on conventional chest radiographs; describe findings that help localise abnormalities in the anterior, middle or posterior mediastinum. The anterior junction line obliteration, the hilum overlay sign, the preservation of the posterior mediastinal lines and the silhouette sign with the right cardiac border are radiographic signs that allow identification and localisation of anterior mediastinal lesions. Widening of the right paratracheal stripe, distortion of the azygo-oesophageal recess and the convex border of the aortopulmonary window indicate the presence of a middle mediastinal abnormality. Thickening, distortion or disruption of paraortic and paraspinal lines and posterior junction line obliteration are caused by posterior mediastinal lesions. Knowledge of normal radiographic mediastinal anatomy and mediastinal lines is crucial to identifying subtle mediastinal abnormalities that can be easily missed on conventional radiography. Moreover, this approach allows identification of the involved mediastinal compartment on chest radiographs, thereby directing the most appropriate further diagnostic workup.

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.

High-resolution CT of nontuberculous mycobacteria pulmonary infection in immunocompetent, non-HIV-positive patients.

PURPOSE: The objective of this study was to demonstrate that nontuberculous mycobacteria (NTM) pulmonary infections are not so infrequent and that the diagnosis may be suggested on the basis of the high-resolution computed tomography (HRCT) pattern alone. MATERIALS AND METHODS: We retrospectively reviewed HRCT scans of 29 patients (9 men, 18 women; mean age 63 years, range 38-88 years) with positive culture from bronchial wash. Mycobacterium avium complex (MAC) was present in all (with the exception of one in whom the NTM was indistinct). In six patients, MAC was associated with M. chelonae, M. kansasii, M. fortuitum or M. xenopi. In one of these patients, MAC was associated with both M. fortuitum and M. chelonae. All patients had had nonspecific symptoms of pulmonary infection for a time ranging from 6 months to 12 years. Previous tuberculous infection was present in five patients (18.5%). Eleven patients had other pulmonary diseases (40.8%), and 12 had associated systemic diseases (44.4%). RESULTS: HRCT findings were apical fibrotic scarring (n=8; 29.6%), consolidations (n=16; 59.2%), single/multiple nodules >1 cm (n=8, multiple; 29.6%), cavitations (n=7; 25.9%), ground glass appearance (n=3; 11.1%), reticular/reticulonodular pattern (n=6; 22.2%), bronchiectasis (n=25; 92.5%), centrilobular nodules (tree in bud) (n=24; 88.8%), air trapping (n=8; 29.6%), lymphadenopathy >1 cm, also with calcification (n=13, 3 with calcification; 48.1%) and pleural effusion (n=2; 7.4%). In 3/7 patients with nodules >1 cm and with cavitations, the "feeding bronchus sign" (a patent bronchus running into a cavitation) was present. Lesions were in the upper lobes in 23 (85.1%), middle lobe/lingula in 25 (92.5%) and lower lobes in 18 (66.6%) patients. The findings were diffuse in 13 (48.1%) cases and patchy in 17 (62.9%). CONCLUSIONS: HRCT findings are essential for the diagnosis of NTM pulmonary infection. The presence of bronchiectasis, cavitary nodules with feeding bronchus sign and tree-in-bud nodules in the middle lobe and lingula are suggestive of NTM infection, thus assisting the physician in the diagnostic workup of these patients.

Structured reporting of chest CT in COVID-19 pneumonia: a consensus proposal.

OBJECTIVES: The need of a standardized reporting scheme and language, in imaging of COVID-19 pneumonia, has been welcomed by major scientific societies. The aim of the study was to build the reporting scheme of chest CT in COVID-19 pneumonia. METHODS: A team of experts, of the Italian Society of Medical and Interventional Radiology (SIRM), has been recruited to compose a consensus panel. They used a modified Delphi process to build a reporting scheme and expressed a level of agreement for each section of the report. To measure the internal consistency of the panelist ratings for each section of the report, a quality analysis based on the average inter-item correlation was performed with Cronbach's alpha (Cα) correlation coefficient. RESULTS: The overall mean score of the experts and the sum of score were 3.1 (std.dev. ± 0.11) and 122 in the second round, and improved to 3.75 (std.dev. ± 0.40) and 154 in the third round. The Cronbach's alpha (Cα) correlation coefficient was 0.741 (acceptable) in the second round and improved to 0.789 in the third round. The final report was built in the management of radiology report template (MRRT) and includes n = 4 items in the procedure information, n = 5 items in the clinical information, n = 16 in the findings, and n = 3 in the impression, with overall 28 items. CONCLUSIONS: The proposed structured report could be of help both for expert radiologists and for the less experienced who are faced with the management of these patients. The structured report is conceived as a guideline, to recommend the key items/findings of chest CT in COVID-19 pneumonia.

Mirtogenol® supplementation in association with dorzolamide-timolol or latanoprost improves the retinal microcirculation in asymptomatic patients with increased ocular pressure.

OBJECTIVE: Supplementation with Mirtogenol® improves the retinal microcirculation and reduces intraocular pressure (IOP) in ocular hypertension, when administrated either alone or in association with an ophthalmic solution (latanoprost). In this study, microcirculatory parameters (perfusion of the circle of Zinn-Haller and retinal circulation) and oxidative stress were tested to assess the effects of Mirtogenol® plus traditional antihypertensive drugs in patients with elevated IOP. PATIENTS AND METHODS: 88 otherwise healthy patients with increased IOP were followed-up in a supplement registry for 12 weeks. Three groups received; (a) dorzolamide-timolol plus Mirtogenol®; (b) latanoprost drops plus Mirtogenol® or (c) latanoprost only. Oral supplementation consisted of two tablets/day of Mirtogenol® (80 mg of bilberry extract, Mirtoselect® plus 40 mg of Pycnogenol®). IOP, retinal blood flow, perfusion of the circle of Zinn-Haller, and oxidative stress were measured during the registry period. RESULTS: The three study groups were comparable; IOP and ocular blood flow velocity at inclusion were also comparable. Over the study period the decrease in IOP and the improvements in retinal microcirculation were statistically significant for all management groups, with a marginally more evident benefit in Mirtogenol®+latanosprost-treated patients. At 12 weeks, the altered perfusion at the circle of Zinn-Haller was improved in all groups; patients using Mirtogenol® showed a better perfusional pattern compared with subjects using only latanoprost. A reduction in oxidative stress was observed in supplemented subjects at the end of the study period; no significant change was seen in non-supplemented patients. All managements were well-tolerated without side effects. CONCLUSIONS: Supplementation with Mirtogenol®, in addition to local ophthalmic treatments, is safe and may contribute as a supplementary management to reach a normal IOP and ocular microcirculatory parameters.

Supplementation with a lecithin-based delivery form of Boswellia serrata extract (Casperome®) controls symptoms of mild irritable bowel syndrome.

OBJECTIVE: Irritable Bowel Syndrome (IBS) is a chronic, gastrointestinal disorder in which abdominal pain or discomfort is associated with defecation or changes in bowel habits. Its multifactorial pathophysiology leads to a variety of available treatments, mainly aimed at controlling symptoms. The management of IBS patients could be optimized by individualized strategies, including non-pharmaceutical approaches. In this study, we evaluated the efficacy and safety of a novel delivery form of Boswellia serrata extracts (BSE) (Casperome®) in patients with IBS. PATIENTS AND METHODS: 71 otherwise healthy subjects with idiopathic IBS were recruited. Participants were assigned to the following management strategies: hyoscine butylbromide; papaverine hydrochloride + A. belladonna extract; supplementation with Casperome®. Predominant IBS symptoms were evaluated at inclusion and at the end of the observational period (4 weeks). The numbers of subjects who needed rescue medication or medical attention/hospital admission were recorded. Adverse events were also evaluated. RESULTS: In all groups, the IBS symptoms investigated, namely abdominal pain, altered bowel movements, meteorism and cramps improved during the observational period. Of note, the number of subjects who needed medical attention significantly decreased only in Casperome®-supplemented group. In addition, Casperome® supplementation was related to a lower incidence of side effects (mainly stypsis). CONCLUSIONS: This preliminary study suggests that Casperome® supplementation could represent a promising alternative approach to manage symptoms associated with IBS in otherwise healthy subjects.

Effects of a curcumin-based supplementation in asymptomatic subjects with low bone density: a preliminary 24-week supplement study.

OBJECTIVE: Osteopenia is a chronic bone condition characterized by decreased calcification, density, or bone mass that, if untreated, can lead to osteoporosis and bone fractures. Although its increasing prevalence, nowadays osteopenia is not adequately prevented and managed. In this study, we evaluated the efficacy, in term of changes in bone density, and safety of an oral formulation based on turmeric phytosome (Meriva®), in subjects suffering from low bone density. PATIENTS AND METHODS: 57 otherwise healthy subjects with low bone density were enrolled in this pilot, supplement study. Informed participants freely decided to follow either a standard management (SM) to control low bone density (control group=28) or SM associated with a curcumin-based oral supplementation (supplement group=29). The bone densities of heel, small finger and upper jaw were evaluated at inclusion and at different time points during the observational period (4, 12 and 24 weeks), in all subjects. RESULTS: The bone density of the heel measured by the Sahara densitometer remarkably improved in the Meriva®-supplemented group, with a significant decrease of ultrasounds transmission values at week 12 (-18.4%) and at week 24 (-21.0%), compared with baseline values. The bone densities of small finger and upper jaw also significantly increased during the study in supplemented subjects, reaching +7.1% and +4.8%, respectively, at week 24, with respect to values at inclusion. Noteworthy, no significant changes of heel, small finger and upper jaw densities were observed in the control group. Last, no safety and tolerability issues were reported during the observational period. CONCLUSIONS: This preliminary study suggests that a curcumin-based supplementation in combination with an appropriate lifestyle could be beneficial in the prevention and management of osteopenia.

Effectiveness of a novel boswellic acids delivery form (Casperome®) in the management of grade II ankle sprains due to sport trauma - a registry study.

OBJECTIVE: In this study, we evaluated a novel delivery form of boswellic acids (Casperome®) in the management of signs and symptoms associated with ankle sprain grade II due to sport trauma. PATIENTS AND METHODS: In this supplement registry study, 72 otherwise healthy subjects with grade II ankle sprain induced by sport activities were advised to either follow a standard management (SM, 37 subjects) for the condition or the SM with the additional daily intake of 1 tablet containing 250 mg Casperome® (35 subjects). Subjects were allowed to use rescue medications (ketoprofen tablets, 25 mg/tablet), and their intake was measured at the end of the management period of 7 days. Each individual was subjected to several non-invasive examinations (self-reported pain at rest and under moderate exercise, range of active and passive movement, presence of local hematomas by ultrasonography) at the following time periods: at inclusion, to evaluate the basal conditions of the subject before the beginning of the study, at day 3 and at the end of the week to evaluate the response differences between the two groups. Additionally, a blood sample from the Casperome® treated subjects (34 out of 35 subjects) was taken at day 7 and analyzed for the systemic concentration of boswellic acids. RESULTS: The 72 individuals recruited in this study spontaneously decided which management to follow, either SM (n=37) or SM+Casperome® (n=35). Supplementation with Casperome® 250 mg/day showed beneficial effects in the reduction of signs and symptoms of ankle sprains evaluated at day 3 and day 7, and was shown to induce measurable plasma level of boswellic acids. Moreover, the supplementary use of Casperome® was well-tolerated and devoid of side effects. CONCLUSIONS: Our pilot registry study showed the effectiveness of Casperome® supplementation in improving recovery after ankle sprain of mild severity (grade II), suggesting a potentially beneficial role in relieving the trauma associated with sport activities and in decreasing the use of rescue drugs.

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.

Supplementation with high titer cranberry extract (Anthocran®) for the prevention of recurrent urinary tract infections in elderly men suffering from moderate prostatic hyperplasia: a pilot study.

OBJECTIVE: Recently, cranberry extracts have been tested as a nutritional supplementation in the prevention of lower urinary tract symptoms (LUTS) as well as recurrent urinary tract infections (UTIs) in subjects at risk, with mixed results. However, evidence of efficacy should be considered only for well-characterized and standardized products in a more selected study population. Moreover, the efficacy of these interventions in elderly must be further investigated. The aim of this pilot, registry study was to evaluate the prophylactic effects of an oral supplementation containing a highly concentrated and standardized cranberry extract reproducing the natural total profile of cranberry fruits, in elderly men with benign prostatic hyperplasia (BPH), suffering from recurrent UTIs, over a 2-months follow-up. PATIENTS AND METHODS: 43 men (age > 65 years) enrolled in this study freely decided to receive either a standard management (SM) only (n = 21) or SM associated with an oral supplementation (n = 23). Supplementation consisted in a daily administration of one capsule containing cranberry extract (Anthocran®) for 60 consecutive days. The clinical effectiveness in the prevention of UTIs was determined by the number of UTIs in the two months before the inclusion in the registry and during the supplementation period, and the number of symptom-free subjects during the registry period. Safety considerations were also performed. RESULTS: In the supplemented group, the mean number of UTI episodes reported during the registry (0.8 ± 0.5) significantly decreased compared with inclusion time (3.2 ± 1.3), p-value = 0.0001. No significant changes were observed in control, SM-only group. Importantly, the cranberry oral supplementation was superior over SM at reducing the mean number of UTIs (p-value = 0.0062). CONCLUSIONS: These results suggest that cranberry supplementation could be an effective and safe approach, within an SM program, for the prevention of recurrent UTIs in elderly men suffering from BPH avoiding some antibiotic treatments.

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.

Bilberry extracts are not created equal: the role of non anthocyanin fraction. Discovering the "dark side of the force" in a preliminary study.

OBJECTIVE: Several experimental studies and clinical trials support the potential of bilberry (Vaccinium myrtillus L) extracts in promoting eye health and circulation. Many active ingredients have been isolated from the berries and leaves of the bilberry plant. However, anthocyanins represent the most widely studied bioactive compounds in this plant. PATIENTS AND METHODS: The aim of this registry, supplement study was to evaluate the effects of Mirtoselect® (standardized in 36% anthocyanins and obtained by an industrial extraction process that preserves the full range of the non-anthocyanin components, mainly natural sugars and polyphenols) in different types of retinal vasculopathies. In total, 140 patients with different types of retinopathy spontaneously decided to join one of the following groups: standard management (SM) only (n=38); SM associated with Mirtoselect® supplementation (n=47); SM associated with a generic bilberry extract supplementation (n=55). Retinal circulatory parameters and flow measurements of the retinal vessels were evaluated at the inclusion and after 6-months supplementation. RESULTS: Overall, significant improvements in several retinal circulatory parameters such as retinal blood flow velocity, with respect to the values at inclusion, were observed in both supplementation groups, especially in Mirtoselect® supplementation group. However, at 6 months, inter-group comparison revealed a statistical advantage in all tested parameters for Mirtoselect® supplementation groups. No side effects or tolerability concerns were reported. CONCLUSIONS: Our registry study suggests that Mirtoselect® supplementation could represent an effective and safe integrated approach for the treatment of different retinopathies.

Managing ulcerative colitis in remission phase: usefulness of Casperome®, an innovative lecithin-based delivery system of Boswellia serrata extract.

OBJECTIVE: Boswellia serrata extracts (BSE) have been traditionally used for the treatment of several inflammatory diseases. The aim of this study was to evaluate the efficacy of a novel delivery form of BSE (Casperome®) in Ulcerative Colitis (UC) during minimally symptomatic remission phase. PATIENTS AND METHODS: In this open-label, observational, registry study, informed participants with UC in remission phase (n = 43) freely decided to receive the oral daily Casperome® supplementation (n = 22) or no supplementation (n = 21) for 4 weeks. Several parameters associated with minimally symptomatic UC in remission were evaluated at the inclusion and the end of the study. RESULTS: A significant beneficial effect of Casperome® was observed for all the parameters evaluated, namely: diffuse intestinal pain, evident and occult blood in stools, bowel movements and cramps, watery stools, malaise, anemia, rectal involvement, number of white blood cells as well as need for concomitant drugs and medical attention. Faecal concentration of calprotectin, a marker of bowel inflammation, resulted ameliorated in Casperome® supplemented patients. CONCLUSIONS: Our study showed that Casperome® supplementation attenuates symptoms associated with mild UC in remission, reducing the use of drugs and medical consultations. Therefore, our study suggests that Casperome® supplementation could represent a promising alternative approach to manage minimally symptomatic UC and maintain the remission phase.
