Introduction

There is still controversy regarding the exercise characteristics that are more effective for improving peak oxygen uptake (VO2 peak), cardiac and metabolic function. High- intensity interval exercise training (HIIT) has been shown to elicit comparable and/or superior performance on endurance capacity (EC), ventricular function (VF) and quality of life. By other side, there is robust evidence that combined endurance and strength training is significantly more effective than endurance training only for improving EC, muscle mass and muscle strength.

There is no enough information if the combination of HIIT with high strength training (HST) could enhance the physical conditions of these patients.

Purpose

The purpose of our study was to analyze the combination of HIIT + HST and its effect on physical performance compared to different types of combined training: HIIT and MCT with low load resistance training (RT) and HIIT or MCT only.

Methods

We evaluated 140 male patients (p) with CAD documented by angiographic studies, clinically stables with medical treatment and sinus rhythm.

All of them performed a stress testing in treadmill without handrail support using a ramp protocol until maximal effort. VO2 peak (ml/kg/min) was measured indirectly through ACSM formula. We used YMCA´s method of estimating body fat with measurement of skinfolds in four sites (BF %), 30-second chair stand test (CST), 8-foot up and go test (FUGT), six-minute walk test (T6min) and one maximum repetition for quadriceps extension (1RMq) .Training intervention: p were randomly allocated to HIIT + RT (n=30), MCT + RT (n=30), HIIT (n=30), MCT (n=30) and HIIT + HST (n=20) during 3 month period of training.

HIIT: 4 x 4 (85-95% peak heart rate) and 60-70% during active breaks. (36 min)

MCT: 70-75% peak heart rate.(36 min)

RT: 40-50% 1RM for lower body with 12-15 repetitions in 2 sets

HST: ≥ 70% 1RM for lower body with low number of repetitions.

Statistical analysis: all data were analyzed using IBM SPSS V.24. Comparisons were performed by following one-way ANOVA(parametric distribution) with post-hoc Tuckey or Kruskal-Wallis(non parametric distribution). The level of statistical significance was P< 0.05.

Results

Analyzing values pretraining (PRE) vs. postraining (POST), VO2 peak increased significantly by 27,52% for HIIT + HST P< 0,03 vs. HIIT + RT- MCT + RT and MCT. A positive effect in HIIT + HST with FUGT P< 0,001 and CST P< 0,005 between group changes and favourable observations in relation to 1RMq (PRE 60,00 ± 9,07 vs. POST 73,00 ± 9,86) and %BF(PRE 26,60 ± 3,21 vs. POST 24,80 ± 3,72) compared to MCT and HIIT P < 0,05. We didn´t find statistical significant differences with both modalities of combined training (low workloads) and HIIT for T6min.

Conclusions

High intensity combined training (HIIT + HST) had an additional effect related to others aerobic and resistance exercises attributed to neuromuscular adaptations, increased power and muscle strength.

Quarantine and Mental Health Challenges for Occupational Medicine: The Case Report of a Nurse Infected With SARS-CoV-2

This case study draws attention to the psychosocial difficulties that emerged in the context of the coronavirus disease 2019 (COVID-19) outbreak in relation to the remote management of subjects with psychiatric vulnerabilities following exposure to prolonged quarantine. The case involves a 56-year-old hospital nurse, followed by the Occupational Health Department of a major university hospital in central Italy for mood instability in the context of a cyclothymic temperament. She was quarantined for occupationally acquired COVID-19 and remained positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) via swab test for more than 2 months between March and May 2020. In this case study, we discuss the challenges presented by the risk of a prolonged quarantine in a psychologically vulnerable employee, the need for occupational medicine to provide adequate health surveillance of all health care workers during the COVID-19 pandemic, the effectiveness of telepsychiatry, and the difficulties in formulating a proper treatment strategy.

Post-traumatic Stress Spectrum and Adult Autism Subthreshold Spectrum in Parents of Children with Epilepsy: Correlations and Gender Differences

Introduction

Data that assess the co-morbidity between post-traumatic stress symptoms and autism spectrum are scarce. Nevertheless, some authors suggested that subjects with autism spectrum disorder (ASD), due to their difficulty in understanding the codes of communication, empathy, expression, are lower resilience to traumas.

Objectives

The aim of this study was to explore in a sample of parents of children with epilepsy, the presence of correlations between the symptoms of post-traumatic stress and adult autism subthreshold spectrum.

Methods

Seventy-seven parents completed the Trauma and Loss Spectrum Self-Report (TALS-SR), specifically modified for one's son epileptic disease, and 72 parents completed the AdAS Spectrum (Adult Autism subthreshold Spectrum).

Results

Eight subjects (11.1%) presented a total score ≥45 at the AdAS Spectrum, corresponding to the satisfaction of a symptomatic ASD criteria and indicative of the Adult Autism Spectrum subthreshold. More specifically, a total score ≥45 was found in 7 (15.9%) of mothers and 1 (3.6%) of the fathers, with no statistically significant differences between the two groups (P = 0.139).

Noteworthy correlations between TALS and AdAS, emerged only in the subgroup of the fathers. In particular, a relevant number of moderate to good correlations emerged between the Domain II (reactions to the events of loss) of the TALS-SR and the AdAS Domain III (non verbal communication), Domain VI (restricted interests and ruminations) and total score.

Conclusions

Results indicate that this peculiar psychopathological model could lead to increased vulnerability to effects of the trauma, in particular in male.

Modification of the Echogenicity of Femoral Plaques after Treatment with Total Triterpenic Fraction of Centella aslatica: A Prospective, Randomized, Placebo-Controlled Trial

The aim of this study was to evaluate whether TTFCA (total triterpenic fraction of Centella asiatica), was effective, by modulating collagen production, in a period of 12 months, increasing the echogenicity of echolucent plaques at the femoral bifurcation. Hypoechoic atherosclerotic plaques have been found to be associated with an increased evidence of cerebrovascular events. In this type of plaques stromal composition is limited as the collagen component is generally very low; the plaque composition is mainly due to lipid accumulation or thrombosis. The aim of this study was the evaluation of echogenicity of hyperechoic plaques and how it could be modified by a drug acting on the modulation of collagen synthesis. Antiplatelet agents were used in all patients; cholesterol-lowering agents were used in 34% of patients in the treatment group and in 36% in the placebo group. TTFCA was used at the dose of 60 mg thrice daily (oral tablets). Of the 60 included subjects 26 completed the study in the treatment group and 24 in the placebo group. At inclusion the average GSM in the treatment group was 14 (SD 3) and 14.3 (SD 3) in controls. At 12 months GSM was increased up to 22.8 (SD 4) in the treatment group and it was 15 (SD 3) in controls. Considering texture no significant changes were observed in controls while a qualitative increase in homogenicity was observed in the TTFCA group. Plaque size measured at the beginning and at the end of the study showed a median increase in size, in controls (23%; range 0%–44%); it was unchanged in the TTFCA group (variation 7%; 4%–26%). In conclusion in the treatment group plaques increased in echogenicity and in homogenicity; size and stenosis remained unchanged. Modulating the scarring process within echolucent plaques (low echogenicity, high echolucency, with a very low collagen/stromal component), possibly by collagen modulation, makes plaques more stable. This has been achieved and documented in the present study by an increase in the gray-scale median (plaques become more echogenic, more ‘white’). The variation in GSM is generally associated with a lower risk of wall thrombosis, rupture and embolization. These observations indicate a positive action of TTFCA on the stabilization of hypoechoic, low-density femoral plaques

Adult Autism Subthreshold Spectrum (AdAS Spectrum) in parents of pediatric patients with epilepsy: Correlations with post-traumatic stress symptoms

Increasing literature has shown the usefulness of a dimensional approach to mental disorders, particularly when exploring subjects exposed to traumatic experiences such as a severe illness in one's child. Recent evidence suggests an increased vulnerability in subjects with autism spectrum symptoms to develop post-traumatic stress symptoms. The aim of the present study was to evaluate the presence of adult autism subthreshold spectrum in a sample of parents of children with epilepsy and its impact on post-traumatic stress spectrum symptoms in the same study sample. Results revealed noteworthy correlations between post-traumatic stress symptoms and adult autism subthreshold spectrum (AdAS Spectrum) only in the subgroup of the fathers. In particular, were evidenced correlations between AdAS Spectrum domain of rumination and narrow interests and some TALS-SR nuclear domains: reaction to traumatic events, reexperiencing and arousal. These findings corroborate the hypothesis that subthreshold autistic features may influence the possible psychopathological reaction to trauma.

Modulation of Inflammation as a Way of Delaying Alzheimer's Disease Progression: The Diet's Role

Background:

Most of the recent reports suggest that inflammatory mediators play a central role in the etiopathogenesis of Alzheimer's disease (AD) and that the conditions leading to a chronic low-grade inflammation, such as stress, depression, obesity and metabolic syndrome, increase the odds of developing Mild Cognitive Impairment (MCI) and AD. Microglia cells are the main actors in the AD process: stimuli from the microenvironment may induce microglia cells to switch to a classically activated inflammatory phenotype M1, or, on the contrary to an alternatively activated M2 phenotype characterized by the secretion of different types of cytokines. Many attempts are currently being made in order to delay the progression of AD by reducing inflammatory mechanisms underlying the disease. Several studies support a relationship among neuroinflammation and nutrients, foods or dietary patterns, taking into account the synergistic or antagonistic biochemical interactions among nutrients as well as the different food sources of the same nutrient. Natural antioxidant and anti-inflammatory compounds found in plant foods, such as fruits, particularly berries (such as strawberry, blueberry, blackcurrant, blackberry, blueberry and mulberry) have been shown to exert neuroprotective activity. It is still unclear whether the dietary bioactive compounds enter the Blood Brain Barrier (BBB) playing a direct antiinflammatory or pro-inflammatory effect on microglia and/or other Central Nervous System (CNS) cells. Another hypothesis is that they may trigger a peripheral reaction that induce indirectly a CNS' response. The subsequent synthesis of cytokines may drive microglia polarization by different ways. So, via an indirect route microglia detects and responds to immune-to-brain signaling.

Conclusion:

This review summarizes current evidence about the potential mechanisms of the interaction among diet, neuroinflammation and AD.

Subthreshold autism spectrum disorder in patients with eating disorders

AIM

Increasingly data suggest a possible overlap between psychopathological manifestations of eating disorders (EDs) and autism spectrum disorders (ASD). The aim of the present study was to assess the presence of subthreshold autism spectrum symptoms, by means of a recently validated instrument, in a sample of participants with EDs, particularly comparing participants with or without binge eating behaviours.

METHODS

138 participants meeting DSM-5 criteria for EDs and 160 healthy control participants (HCs), were recruited at 3 Italian University Departments of Psychiatry and assessed by the SCID-5, the Adult Autism Subthreshold Spectrum (AdAS Spectrum) and the Eating Disorders Inventory, version 2 (EDI-2). ED participants included: 46 with restrictive anorexia (AN-R); 24 with binge-purging type of Anorexia Nervosa (AN-BP); 34 with Bulimia Nervosa (BN) and 34 with Binge Eating Disorder (BED). The sample was split in two groups: participants with binge eating behaviours (BEB), in which were included participants with AN-BP, BN and BED, and participants with restrictive behaviours (AN-R).

RESULTS

participants with EDs showed significantly higher AdAS Spectrum total scores than HCs. Moreover, EDs participants showed significantly higher scores on all AdAS Spectrum domains with the exception of Non verbal communication and Hyper-Hypo reactivity to sensory input for AN-BP participants, and Childhood/Adolescence domain for AN-BP and BED participants. Participants with AN-R scored significantly higher than participants with BEB on the AdAS Spectrum total score, and on the Inflexibility and adherence to routine and Restricted interest/rumination AdAS Spectrum domain scores. Significant correlations emerged between the Interpersonal distrust EDI-2 sub-scale and the Non verbal communication and the Restricted interest and rumination AdAS Spectrum domains; as well as between the Social insecurity EDI-2 sub-scale and the Inflexibility and adherence to routine and Restricted interest and rumination domains in participants with EDs.

CONCLUSIONS

Our data corroborate the presence of higher subthreshold autism spectrum symptoms among ED participants with respect to HCs, with particularly higher levels among restrictive participants. Relevant correlations between subthreshold autism spectrum symptoms and EDI-2 Subscale also emerged.

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.

Full and Partial DSM-5 PTSD in Parents of Children with Epilepsy: Exploring Gender Differences

Introduction

Increasing literature suggests the need to explore PTSD and post-traumatic stress symptoms among parents and caregivers of children with acute and chronic illnesses but scant data are available on epilepsy.

Objectives

The aim of this study was to estimate full and partial PTSD rates among parents of children with epilepsy according to DSM-5 criteria. Further, aim of this study was to examine eventual gender differences between mothers and fathers.

Methods

One hundred and thirty-eight parents, 91 mothers (65.9%) and 47 (34.1%) fathers, of children diagnosed with epilepsy were interviewed using the SCID-5.

Results

Full and partial DSM-5 PTSD were reported by 10.4% and 37.3% of patients, respectively. Significant gender differences, with the mother more affected, emerged in the rates of partial A PTSD rates (P = 0.048) and in the endorsement rates of criterion B (intrusion symptoms) (P = 0.047), criterion D (negative alterations in cognitions and mood) (P = 0.010) and criterion E (alterations in arousal and reactivity) (P < 0.001) too.

Conclusions

This is the first study to identify post-traumatic symptoms in caregivers of pediatric patients with epilepsy with the use of current diagnostic criteria and the relevance of the results suggests the need for further studies on this risk population.

Cognitive disability in alzheimer's disease and its management

Cognitive disability linked to neurodegenerative diseases and in particular to Alzheimer's disease, remains an increasing cause for concern through a dramatic prevalence increment and associated socio-economic burdens. Initially Alzheimer's disease develops asymptomatically with primary clinical signs, such as memory impairment, decline of spatial and perceptual abilities, occurring at a later stage. This delay implies the possibility of promoting early interventions during the pre-symptomatic stage of the disease. Different strategies have been applied in order to prevent/delay onset of Alzheimer's disease or at least to improve quality of life and health conditions of Alzheimer's disease patients and their caregivers, especially in the absence of current viable therapies. Multidomain interventions, aimed at affecting several risk factors simultaneously, offer a versatility that may attain improved outcomes in comparison with single-domain prevention trials. These multidomain interventions involve diet, physical exercise, cognitive training and social activities, while music therapy, improving self-consciousness and reducing neurofibrils, may contribute to deceleration/delay onset of Alzheimer's disease progression. Information and Communication Technology (ICT) provides broad applications to improve quality of life and well-being of Alzheimer's disease patients and caregivers, suffering from psychological distress, as well as reducing additional public health costs.

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.

Variations in Plasma Free Radicals with Topical Aescin + Essential Phospholipids Gel in Venous Hypertension: New Clinical Data

The aim of this study was the evaluation of the effects of Aescin + essential phospholipids (AEPL) gel on plasma free radicals (PFRs). In this study, ten patients with venous hypertension, no ulcerations or infections, venous microangiopathy, and varicose veins were treated with topical AEPL applied in a standard protocol. AEPL was applied for 2 weeks, three times daily at the same skin region (perimalleolar internal region at defined distance from the medial malleolus and from the anterior edge of the tibia). In subjects with venous hypertension, PFR values were higher than 420 Carr units. After treatment, the values of PRF decreased to almost normal as an effect of the massage with AEPL gel. The decrease in value was observed in all treatment subjects. A ranking system indicates that the AEPL preparation is active in all subjects who have venous microangiopathy. The decrease in PFR value was greater than 30% in all treatment subjects (p<0.05). The decrease in PFR can be considered an important indication of an improvement in skin perfusion, which protects the skin from deterioration and eventually from venous ulcerations. The evaluation of PFR is an important new physiologic parameter that can be associated with other noninvasive tests to study the microcirculation and its evolution and improvement with systemic or topical medical treatment.

Management of Superficial Vein Thrombosis and Thrombophlebitis: Status and Expert Opinion Document

Superficial vein thrombosis is characterized by clotting of superficial veins (ie, following direct trauma) with minimal inflammatory components. Superficial thrombophlebitis is a minimally thrombotic process of superficial veins associated with inflammatory changes and/or infection. Treatments generally include analgesics, elastic compression, anti-inflammatory agents, exercise and ambulation, and, in some cases, local or systemic anticoagulants. It is better to avoid bed rest and reduced mobility. Topical analgesia with nonsteroidal, anti-inflammatory creams applied locally to the superficial vein thrombosis/superficial thrombophlebitis area controls symptoms. Hirudoid cream (heparinoid) shortens the duration of signs/symptoms. Locally acting anticoagulants/antithrombotics (Viatromb®, Lipohep ®, spray Na-heparin) have positive effects on pain and on the reduction in thrombus size. Intravenous catheters should be changed every 24 to 48 hours (depending on venous flow and clinical parameters) to prevent superficial vein thrombosis/superficial thrombophlebitis and removed in case of events. Low molecular weight heparin prophylaxis and nitroglycerin patches distal to peripheral lines may reduce the incidence of superficial vein thrombosis/superficial thrombophlebitis in patients with vein catheters. In case of superficial vein thrombosis/superficial thrombophlebitis, vein lines should be removed. In neoplastic diseases and hematological disorders, anticoagulants may be necessary. Exercise reduces pain and the possibility of deep vein thrombosis. Only in cases in which pain is very severe is bed rest necessary. Deep vein thrombosis prophylaxis should be established in patients with reduced mobility. Antibiotics usually do not have a place in superficial vein thrombosis/superficial thrombophlebitis unless there are documented infections. Prevention of superficial vein thrombosis should be considered on the basis of patient's history and clinical evaluation.

HR, 0-(Beta-Hydroxyethyl)-Rutosides; (Venoruton®): Rapid Relief of Signs/Symptoms in Chronic Venous Insufficiency and Microangiopathy: A Prospective, Controlled Study

The aim of this independent study was to demonstrate the rapidity of the clinical action of HR 0-(beta-hydroxyethyl)-rutosides, Venoruton® (Novartis Consumer Health) in patients with chronic venous insufficiency (CVI). Two groups of patients with venous hypertension and microangiopathy were treated with HR (1 or 2 g/day, for 8 weeks). Twelve patients (age 56.4; range 44-66; M:F = 6:6) were included in group 1 (1 g/day) (moderate CVI and microangiopathy); 10 patients (age 57.4; range 42-67; M:F = 5:5) in group 2 (2 g/day) with more severe CVI and microangiopathy. Average ambulatory venous pressure (AVP) was 58.6 (range 50-65) with a refilling time (RT) shorter than 10 seconds. There were no significant differences in AVP and RT between the 2 groups, but the duration of the disease was longer in group 2: 3.5 years (SD 2.0) in group 1 and 6.4 years (SD 3.3) in group 2. All included subjects completed the study and no dropouts were observed. In both dose groups there was a progressive decrease in laser Doppler resting flux (RF), indicating improvement in microangiopathy and a significant decrease in capillary filtration (RAS) associated with a significant improvement in analogue scale line score (ASLS) and edema. Although the effect in the 2 g dose group was more rapid on the microcirculatory parameters with a significant effect on RF and RAS after 4 days (effect of 1 g per day after 8 days and 6 days, respectively), there was no difference in the time to onset of a significant clinical improvement (ie, the ASLS and the edema score): 4 days in both groups. Venous microangiopathy and edema were improved by the treatment with HR within a few days. The effects were visible with both dosages, in both severity groups.

Prevention of Edema and Flight Microangiopathy with Venoruton ® (HR), (0-[Beta-Hydroxyethyl]Rutosides) in Patients with Varicose Veins

The aim of this open study was the evaluation of the effects of HR (Venoruton®) at a dose of 1 g/day on the prevention and control of flight microangiopathy and edema in subjects with varicose veins and moderate chronic venous insufficiency flying for more than 11 hours. Patients with varicose veins, edema, but without initial skin alterations or complications, were included. Measurements of skin laser Doppler (LDF) resting flux (RF) venoarteriolar response (VAR), ankle swelling (RAS), and edema were made within 12 hours before and within 3 hours after the flights. The resulting edema after the flights was evaluated with a composite edema score (analogue scale line). A group of 20 subjects was treated with HR (1 g/day, starting 2 days before the flight and 1 g for every 12 hours on day of travel). Another group of 18 subjects formed the control group. The length of the flights was between 11 and 13 hours; all seats were in coach class. Fifty patients were enrolled and 38 patients were evaluable at the end of the trial. The 2 groups (treatment and control) were comparable for age and sex distribution. The decrease in RF was significant in both groups with a higher flux at the end of the flight in the HR group (p<0.05). The venoarteriolar response was decreased at the end of the flights; the decrease was lower in the HR group (p<0.05). The increase in RAS and the edema score were significantly lower in the HR group. In conclusion HR is useful for reducing the level of microangiopathy and the increased capillary filtration and in controlling edema in patients with venous disease in long flights. The higher level of flux and VAR and the reduction in edema indicate a positive effect of HR on the microcirculation. This study confirms that HR prophylaxis is effective to control flight microangiopathy associated with edema.

Miraqule-C and mild heart failure: an 8-week registry

The aim of this registry study was the evaluation of possible benefits of a supplement including CoenzymeQ10 and a grape seed combination (MiraQule C, Alchem) in stable, moderate, heart failure patients.

RESULTS

The mean age of the 18 supplemented patients was 60.1;2 years (the age of the 22 controls was 61.1;2.2). The two groups were comparable. There were no dropouts in the two groups. In the 8 weeks of the registry, all supplemented patients remained in the NYHA class while 7 out of 22 in controls increased the level of heart failure passing into Class III. Systolic- diastolic pressure, heart rate, respiratory rate were minimally (non significantly lowered) with the supplement without differences controls. Ultrasound-derived ejection fraction was increased by supplementation (median of 2.7%) in the CoQ10 group (p<0.05) while there were minimal, non- significant differences in controls. Walking distance on treadmill was also significantly increased with the supplement (p<0.05) and only marginally in controls. The microcirculation (laser Doppler parameters and transcutaneous PO2, PCO2) improved significantly in the MQ-C group (p<0.05) and only marginally in controls. Oxidative stress was significantly decreased (p<0.05) with the CoQ10 preparation while there were minimal. Non-significant changes were observed in in controls. Tolerability and compliance were optimal (with more than 95% of the capsules correctly used). In conclusion in this supplement registry Miraqule-C seem to help patients with moderate heart failure and should be considered for larger studies.

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.

Recurrence of retinal vein thrombosis with Pycnogenol® or Aspirin® supplementation: a registry study

AIM

The aim of this study was to use Pycnogenol® to reduce the recurrence of retinal vein thrombosis (RVT) after a first episode. Pycnogenol® is an anti-inflammatory, anti-edema and an antiplatelet agent with a "mild" antithrombotic activity. The registry, using Pycnogenol® was aimed at reducing the number of repeated episodes of RVT.

METHODS

Possible management options--chosen by patients--were: standard management; standard management + oral Aspirin® 100 mg once/day (if there were no tolerability problems before admission); standard management + Pycnogenol® two 50 mg capsules per day (for a total of 100 mg/day). Number of subjects, age, sex, distribution, percentage of smokers, and vision were comparable.

RESULTS

Recurrent RVT was seen in 17.39% of controls and in 3.56% of subjects supplemented with Pycnogenol® (P<0.05 vs. controls). There was RVT in 15.38% of the subjects using Aspirin®. The incidence of RVT was 4.88 times higher with standard management in comparison with the supplement group and 4.32 lower with Pycnogenol® supplementation in comparison with Aspirin®. Vision level was better with Pycnogenol® (20/25 at nine months; P<0.05). With Pycnogenol®, edema at the retinal level was also significantly reduced compared to the other groups. Pycnogenol® has a very good safety profile. In the Aspirin® group 26 completed 9 months and 6 subjects dropped out for tolerability problems. In the Aspirin® group, 2 minor, subclinical, retinal, hemorrhagic episodes during the follow-up were observed (2 subjects out of 26, equivalent to 7.69%). This pilot registry indicates that Pycnogenol® seems to reduce the recurrence of RVT without side effects. It does not induce new hemorrhagic episodes that may be theoretically linked to the use of Aspirin® (or other antiplatelets).

CONCLUSION

Larger studies should be planned involving a wider range of conditions, diseases and risk factors associated to RVT and to its recurrence.

Adult separation anxiety differentiates patients with complicated grief and/or major depression and is related to lifetime mood spectrum symptoms

BACKGROUND

Increasing literature has been focused on complicated grief (CG) and its distinctiveness from other potentially loss related mental disorders such as major depression (MD). In this regard, symptoms of separation distress seem to play a key role. The aim of this study was to compare the clinical features of CG to those of MD and of CG+MD, with particular attention to separation anxiety.

METHODS

Fifty patients with CG (26 with and 24 without MD) and 40 with MD were consecutively recruited. Assessments included: SCID-I/P, Inventory of Complicated Grief (ICG), Adult Separation Anxiety Symptom Questionnaire (ASA-27), Work and Social Adjustment Scale (WSAS), Mood Spectrum-Self Report (MOODS-SR)-lifetime version.

RESULTS

Patients with MD reported significantly higher ASA-27 scores than patients with CG either alone or with MD. In all groups, ASA-27 total scores were significantly correlated with the MOODS-SR total scores and with those of its depressive component and rhythmicity domain. No significant differences were reported in the WSAS scores.

LIMITATIONS

Major limitations are the small sample size and the use of lifetime instruments.

CONCLUSIONS

Our results suggest a correlation between adult separation anxiety symptoms and lifetime mood spectrum symptoms both in patients with CG and MD. Further studies are needed to better understand the role of adult separation anxiety in the development of these disorders and for their nosographic autonomy as well.

Pycnogenol® and Centella asiatica in the management of asymptomatic atherosclerosis progression

AIM

The aim of the study was to evaluate the effect of the nutritional supplements Pycnogenol® and total triterpenic fraction of Centella asiatica (TTFCA) on atherosclerosis progression in low-risk asymptomatic subjects with carotid or femoral stenosing plaques.

METHODS

This was an observational pilot, substudy of the San Valentino epidemiological cardiovascular study. The study included 824 subjects aged 45-60 without any conventional risk factors who had a stenosing atherosclerotic plaque (>50-60%) in at least one carotid or common femoral bifurcation, allocated into 6 groups: Group 1 (Controls): management was based on education, exercise, diet and lifestyle changes. This same management plan was used in all other groups; group 2: Pycnogenol® 50 mg/day; group 3: Pycnogenol® 100 mg/day; group 4: Aspirin® 100 mg/day or ticlopidine 250 mg/day if intolerant to aspirin; group 5: Aspirin® 100 mg/day and Pycnogenol® 100 mg/day; group 6: Pycnogenol® 100 mg/day plus TTFCA 100 mg/day. The follow-up lasted 42 months. Plaque progression was assessed using the ultrasonic arterial score based on the arterial wall morphology and the number of plaques that progressed and on the number of subjects that had cardiovascular events. A secondary endpoint was to evaluate the changes in oxidative stress at baseline and at 42 months.

RESULTS

The ultrasonic score increased significantly in groups 1, 2, and 4 (>1%) but not in groups 3, 5 and 6 (<1%) suggesting a beneficial effect of Pycnogenol® 100 mg. Considering the percent of patients that progressed from class V (asymptomatic) to VI (symptomatic) there was a progression of plaques in 48.09% of controls. In the Pycnogenol® 100 (group 3, 10.4%) and in the Aspirin®+ Pycnogenol® (group 5, 10.68%) progression was half of what observed with antiplatelet agent (group 4, 20.93%); in the TTFCA+ Pycnogenol®group (group 6) progression was 7.4 times lower than in controls; 3.22 times lower than in the antiplatelet agents group (4). Events (hospital admission, specialized care) were observed in 16.03% of controls; there were 8.83% of subjects with events with Pycnogenol® 50 mg and 8% in group 3 (Pycnogenol® 100 mg). In group 4 (antiplatelets), 8.52% of subjects had events; in group 5, 6.87% of subjects had events and in group 6 (TTFCA+ Pycnogenol®) only 4.41% had events (this was the lowest event rate; P<0.05). All treatment groups had a significantly lower event rate (P<0.05) in comparison with controls. Considering treatments groups 2, 3, 5, 6 had a lower number (P<0.05) of subjects in need of cardiovascular management in comparison with controls. The need for risk factor management was higher in controls and lower in group 6 (P<0.05). In groups 2 to 6 the need for risk factor management was lower than in controls (P<0.05). Including all events (hospital admission, need for treatment or for risk management) 51.9% of controls were involved. In the other groups there was a reduction (from a -9.28% reduction in group 2 to a -26% in group 6) (P<0.002). The most important reduction (higher that in all groups; P<0.05) was in group 6. At 42 months, oxidative stress in all the Pycnogenol® groups was less than in the control group. In the combined group of Pycnogenol® and TTFCA the oxidative stress was less than with Pycnogenol® alone (P<0.001).

CONCLUSION

Pycnogenol® and the combination of Pycnogenol® +TTFCA appear to reduce the progression of subclinical arterial plaques and the progression to clinical stages. The reduction in plaque and clinical progression was associated with a reduction in oxidative stress. The results justify a large, randomized, controlled study to demonstrate the efficacy of the combined Pycnogenol® and TTFCA prophylactic therapy in preclinical atherosclerosis.

Cranberry supplementation in the prevention of non-severe lower urinary tract infections: a pilot study

OBJECTIVE

Cranberry extracts have been tested as a nutritional supplementation in the prevention of recurrent lower-urinary tract infections (R-UTIs), with mixed results. This pilot, registry study evaluates the prophylactic effects of oral supplementation with a new well-standardized cranberry extract in patients with R-UTI, over a 2-month follow-up.

PATIENTS AND METHODS

All subjects were suggested to take one capsule containing a cranberry extract (Anthocran™) for 60 days and were also given lifestyle advice. Clinical outcomes were compared between patients on cranberry extracts and those who don't take this supplementation.

RESULTS

In total, 22 subjects completed the study in each of the two groups. In the cranberry group, the reduction in the frequency of UTI episodes during the study period compared with the two months before the inclusion was 73.3% (p < 0.05). This figure was 15.4% in the control group (p < 0.05; p = 0.012 vs cranberry group). Seven (31.8%) subjects in the cranberry group were symptom-free; no patient was symptom-free in the control group (p < 0.05). The mean duration of UTI episodes was 2.5 ± 1.3 days in the cranberry group, compared with 3.6 ± 1.7 days in subjects not on cranberry (p < 0.05). Three subjects (13.6%) in the cranberry group and 8 (36.3%) in the control group required medical consultation for UTI symptoms (p < 0.05). Urine evaluation was completely negative in 20/22 subjects in the Cranberry group (90.9%) and in 11 control subjects (50.0%; p < 0.005). No adverse events were observed.

CONCLUSIONS

These preliminary results, obtained in a field-practice setting, indicates the effectiveness and safety of a well-standardized cranberry extract in the prevention of R-UTI.

Liverubin (standardized silymarin) in the supplementary management of functional, temporary hepatic damage. A pilot, registry, study

AIM

Mild, temporary hepatic failure (MTHF) may be completely asymptomatic or cause minimal signs and symptoms. This common clinical problem is very diffuse and, in case of repeated episodes may cause a chronic impairment in liver function. The aim of this registry was to evaluate the evolution of MTHF in subjects using Liverubin (a new standardized Silymarin preparation) over a 4-week period.

METHODS

Patients with MTHF were observed in a registry study. In all subjects viral hepatitis markers were negative at inclusion. Different possible causes of MTHF had been considered, documented or excluded. The role of alcohol was mainly as a "facilitator" and not definitely determinant as a single factor in causing the MTHF episode. The registry included patients with MTHF characterized by: decreased albumin levels; increased total bilirubin; altered hepatic functions enzymes; increased oxidative stress. Two management groups were created: a. standard management (SM) only; b: SM and Liverubin; 25 Liverubin patients and 23 SM subjects completed the registry. The average follow-up period was 32.2;1.3 days in the supplement group and 32.1;2 days in controls.

RESULTS

The distribution of symptoms and ultrasound results were comparable. Most symptoms observed at inclusion were disappeared or attenuated at 4 weeks in both groups. At inclusion, the values in the two groups were comparable. The increase in albumin levels was significantly (P<0.05 at 4 weeks) faster and the final values were higher in the Liverubin group. Total bilirubin was reduced in the supplement group better than in controls (P<0.05). Direct bilirubin values improved more in the supplement group at 4 weeks (P<0.05). The decrease of ALT-SGPT and AST-ASAT was more evident in the supplement group (P<0.05). Improvement in controls was more limited. Alkaline phosphatase value was normalized at 4 weeks in Liverubin patients; values decreased less in controls (P<0.05). Gamma GT decreased and were normal at 4 weeks with Liverubin. ESR was decreased in both groups (significantly more in the Liverubin group: P<0.05). There was a less important decrease in controls without normalization at 4 weeks. The white cell count was also better at 4 weeks in the supplement group; P<0.05). Plasma free radicals were significantly elevated in both groups at inclusion. A more significant decrease in the supplement group was observed at 4 weeks. Persisting, elevated values were seen in controls (P<0.05 in comparison with normal range). Platelets values improved in the Liverubin group (P<0.05) better than in controls. All other blood tests values (including hematocrit, renal function tests) were within the normal range at inclusion and at 4 weeks in both groups. Hepatitis markers were negative at inclusion and at 4 weeks. Compliance. Ninety-six percent of the Liverubin capsules were correctly used. 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.

Beanblock® (standardized dry extract of Phaseolus vulgaris) in mildly overweight subjects: a pilot study

OBJECTIVE

This study evaluates the efficacy of Beanblock®, a standardized extract of Phaseolus vulgaris L., on weight control in healthy overweight subjects on a weight management plan that combined lifestyle and dietary advice.

PATIENTS AND METHODS

Sixty overweight (BMI 25-30 kg/m2) healthy subjects were enroled. All subjects were instructed to follow a weight management plan, accompanied by dietary advice. Thirty subjects used Beanblock® for at least 12 weeks (50 mg tablets, two times daily). The remaining 30 subjects did not receive any supplementation (management-only). The main endpoints were changes in body weight and waist circumference, with plasmatic oxidative stress, satiey and appetite being also evaluated.

RESULTS

At week 12, the supplementation with Beanblock® was associated with a reduction in body weight (from 82.8 ± 9.1 kg to 78.8 ± 8.9 kg; p < 0.0001) and a decrease of waist circumference from 94.4 ± 10.3 cm to 88.2 ± 10.0 cm (p < 0.0001). Conversely, only marginal changes were observed in the control group. Oxidative stress was also significantly decreased with Beanblock® (from 380.4 ± 14.8 to 340.7 ± 14.8 Carr Units; p < 0.0001). Satiety and appetite improved in the supplement group. No side effects were observed and compliance was optimal.

CONCLUSIONS

Beanblock®, in association with a health management plan, was useful for weight control in mildly overweight healthy subjects.

Improvement in symptoms and cochlear flow with pycnogenol in patients with Meniere's disease and tinnitus

AIM

The aim of this supplement registry was to evaluate the efficacy of the Pycnogenol® in improving cochlear flow and symptoms in a 6-month follow-up for patients with Meniere's disease (MD), tinnitus and cochlear hypoperfusion.

METHODS

Main signs/symptoms were considered: Spontaneous vertigo, positional vertigo, hearing loss, tinnitus, pressure in the ear, unsteady gait, associated clinical problems, alterations in daily life. All subjects were managed with the best available management (BM); one group used the supplement Pycnogenol (150 mg/day). Cochlear flow and tinnitus were also evaluated. Out of 120 patients incuded in the registry, 55 used Pycnogenol and 52 (controls) were managed only with BM.

RESULTS

There was a more significant improvement in all registry items at 3 and 6 months in the Pycnogenol group (P<0.05). The number of lost working days was lower in the Pycnogenol group. At 3 months, 45.4% of subjects using Pycnogenol were completely asymptomatic in comparison with 23.07% of controls. At 6 months 87.3% of the Pycnogenol subjects were asymptomatic compared with 34.6% of controls. Cochlear flow velocity was significantly better (higher flow, higher diastolic component) in the Pycnogenol group (P<0.05). The subjective tinnitus scale decreased in both groups (P<0.05); the decrease was more significant in Pycnogenol subjects (P<0.05) at 3 and 6 months.

CONCLUSION

Symptoms of Meniere's disease, flow at cochlear level and tinnitus improved in Pycnogenol subjects in comparison with best management.

Improvement in signs and symptoms in psoriasis patients with Pycnogenol® supplementation

AIM

The aim of the study was the evaluation of supplementation with Pycnogenol®, French maritime pine bark extract (registered trademark of Horphag Research Ltd.) to improve the effects of the management of psoriasis and reduce the need for treatments.

METHODS

Patients (age range 30-45) with moderate/severe plaque psoriasis were included in a 12-week registry study that did not interfere with 'standard management'. The minimum Psoriasis Area Severity Index (PASI) score at inclusion was 10. Subjects with 10-29% (grade 2) and 30-49% (grade 3) of involved area were included. Oxidative stress (plasma free radicals) was measured. Patient-reported measures included the Dermatology Life Quality Index (DLQI). The supplement was used at a dosage of 150 mg/day (50 mg three times daily).

RESULTS

The two registry groups (standard management and standard management+supplementation) were comparable. Dropouts were due to logistical problems. Single PASI items were evaluated: a decrease in the affected body area in boths groups was observed. The decrease in affected areas was more pronounced in the Pycnogenol group in all body regions. The severity score (erythema, induration, desquamation) improved more significantly with Pycnogenol. Considering the water content of skin in all areas, the increase was higher with Pycnogenol. The quantity of exfoliating cells (score from -5 to +5) was significantly reduced in both groups, with a better action using Pycnogenol. Skin moisture improved with treatment in all subjects, with better effects using Pycnogenol. Using a modified (12 items) DLQI indicating how much psoriasis had affected the patient's life in the previous week, Pycnogenol-supplemented subjects performed better for each single parameter in comparison with standard management. Improvement in the treatment time (-32% in comparison with standard management) and costs (decreased on average 36.4% in comparison with standard management) were observed in the supplement group. A decrease in consumption of other drugs was observed with the supplement. Oxidative stress was significantly lower in the supplement group at 12 weeks.

CONCLUSION

These results indicate the efficacy of Pycnogenol supplementation in improving control of the most common clinical aspects of psoriasis and in reducing oxidative stress. Further studies may indicate the possible systemic or local use of Pycnogenol and its role in controlling side effects and costs of standard management.

Pycnogenol® in postpartum symptomatic hemorrhoids

AIM

The aim of this registry study was to evaluate the efficacy of Pycnogenol® (Horphag Research Ltd.), a standardized extract from the French maritime pine bark, to control signs/symptoms and prevent complications associated with hemorrhoids in the months after delivery in healthy women.

METHODS

Women with hemorrhoids after their second pregnancy were included within the third month after pregnancy. Pycnogenol dosage was 150 mg/day for 6 months. Symptoms for 4th and 3rd degree hemorrhoids were evaluated.

RESULTS

The registry groups were comparable. For 4th degree hemorrhoids, main symptoms were reduced after 6 months in all patients, but the group using Pycnogenol in addition to standard best management showed more improvement. In patients with 3rd degree hemorrhoids, symptoms were reduced in both management groups at 6 months; with Pycnogenol the reduction in symptoms scores was significantly better. At 6 months 18/24 subjects (75%) in the Pycnogenol group were symptom-free in comparison with 14/25 (56%) in controls. In the 4th degree hemorrhoid group, 7/10 patients (70%) in the Pycnogenol group were symptom-free at 6 months in comparison with 4/11 subjects (36%) in the best management group. No significant side effects were observed.

CONCLUSION

Pycnogenol appears to positively affect hemorrhoid signs and symptoms in the months after pregnancy.

Improvement of common cold with Pycnogenol®: a Winter registry study

AIM

This registry study aimed to evaluate the use of Pycnogenol® (pine bark extract), an anti-inflammatory, anti-oxidant and anti-edema natural compound, on symptoms of common cold. Main targets were the evaluation in otherwise healthy subjects of signs/symptoms, the reduction in days of disease, and the prevention of complications.

METHODS

All subjects used the "best management" for colds and one group added Pycnogenol® capsules (50 mg, bid/die) from day zero. The resulting registry groups were comparable. A total of 70 subjects used Pycnogenol® and 76 acted as controls.

RESULTS

The number of days with a perceived cold affecting the patients was reduced in the supplement group (3.1;0.4 days) in comparison with controls (4.2;0.2). Lost working days were significantly decreased in the supplement group (0.55;0.3 versus 0.67;0.3 in controls). The need to use any other compound (on demand basis; OTC products) to manage symptoms and the occurrence of any clinically significant complications were significantly lower in the Pycnogenol® group. The most frequent complications were the extension of the cold to a period longer than 4 days, a tracheal extension and a bronchial involvement. Pycnogenol® was significantly effective in reducing the number of complications. The daily evolution of the "pillar cold signs" indicates a significantly faster resolution in the supplement group. With supplementation the decrease in symptom scores appears to be significantly more important. Pycnogenol® supplementation appears to make regression faster for all symptoms in comparison with controls.

CONCLUSION

In this pilot registry, Pycnogenol® appears to decrease symptoms of cold and shorten its course also preventing some complications.

Thyroid cysts treatment with the sclerosing agent Atossiclerol. Long-term (5 to 15 years) follow-up

AIM

The aim of this study was to evaluate the long-term efficacy of the sclerosing agent Atossisclerol in the treatment of benign, ecolucent, thyroid cysts.

METHODS

Two groups of cysts, one between 1 and 3 cm and a group smaller than 0.99 mm in maximum diameter (range 0.6-0.99) were considered in the inclusion plan. The localization of the cysts was at lobar level. A limited quantity of Atossisclerol (0.5 to 2%) was injected.

RESULTS

No side effects were noted. After 5 years in the group treated with the sclerosing agent 93% of the cysts were completely disappeared (vs 60% in controls). However the initial target cyst at 5 and years was completely cured in most patients (>80%) treated with the sclerosing agent; at 10 years more than 90% of the original, sclerosed target cysts were not visible. Another control of most of these patients (53/68) at 15 years indicated that sclerosis of the cyst is safe and allow a better occlusion/obliteration (in almost all patients) of the cyst in comparison with aspiration only (slow recurrence in some 25% of the cysts).

CONCLUSION

The sclerosing agent can be re-injected in the same patients without significant reaction or clinical problems or immunological reactions.

Meriva®, a lecithinized curcumin delivery system, in diabetic microangiopathy and retinopathy

BACKGROUND

In the present study, the improvement of diabetic microangiopathy and retinopathy was evaluated in 38 diabetic patients treated with a novel curcumin phospholipids delivery form (Meriva®).

METHODS

Diabetes was diagnosed at least 5 years before inclusion and all patients had signs of retinal oedema and of peripheral microangiopathy. Meriva® was administered at the dosage of 2 tablets/day (each tablet containing 500 mg Meriva® corresponding to 100 mg curcumin) for a period of at least 4 weeks in addition to the standard management plan, while a comparable group of subjects (n = 39) followed the standard management plan alone.

RESULTS

All subjects (treatment and controls) completed the follow-up period, there were no dropouts and Meriva® showed an optimal tolerability. At 4 weeks, microcirculatory and clinical evaluations indicated an improvement of microangiopathy. In terms of peripheral microangiopathy, in the Meriva® group, there was a significant improvement in the venoarteriolar response (p<0.05) and a decrease in the score of peripheral oedema (p<0.05), a sign typically associated with the failure of the venoarteriolar response. At the retinal level, high-resolution, duplex scanning, used to measure retinal flow, showed improvements in the Meriva® treated patients. The evaluation of retinal oedema (Steigerwalt's scale) showed an improvement associated with improved visual acuity (Snellen scale). There were no clinical or microcirculatory effects in controls.

CONCLUSION

These preliminary observations, indicate the value of curcumin, when administered in a bioavailable form as with Meriva®, in the management of diabetic microangiopathy and retinopathy.

Latest advancements in the pharmacological treatment of binge eating disorder

BACKGROUND

Binge-eating disorder (BED) is a relatively new disorder characterized by binge eating without purging.

AIM

The purpose of this article is to review the potential use of the recently proposed compounds for the treatment of BED.

MATERIALS AND METHODS

A medline of published articles from 1980 to December 2012 was carried out using the following keywords: BED and treatment, topiramate, zonisamide, ghrelin.

RESULTS

The pharmacological treatment of BED is still heterogenous and poorly established, mainly for the lack of controlled studies in large samples of patients.

CONCLUSIONS

The data on serotonin and norepinephrine reuptake inhibitors and on novel anticonvulsants seem quite promising in terms of efficacy and tolerability. In addition, the preliminary findings on the possibility of modulating appetite through the interference with the ghrelin system suggest new and intriguing ways of intervention in BED.

Rebrota do capim-marandu submetido ao ataque de cigarrinhas

O objetivo deste experimento foi caracterizar e quantificar respostas de Brachiaria brizantha cv. Marandu sob níveis de infestações de cigarrinhas adultas do gênero Mahanarva (Hemiptera: Cercopidae). O ensaio foi realizado em casa de vegetação na Cidade de Piracicaba, SP, e seus tratamentos corresponderam a quatro níveis de infestações de cigarrinhas (5, 10, 20 e 40 insetos adultos vaso-1) mais o controle (sem cigarrinhas), distribuídos nas unidades experimentais (vasos) segundo delineamento inteiramente casualizado. O estudo compreendeu período de infestação pelo inseto e de rebrota das plantas. Avaliaram-se as seguintes variáveis-resposta: acúmulo de forragem, massa de raiz e teor de reservas orgânicas. Não foi observado efeito das cigarrinhas na massa das frações rebrote, resíduo e sistema radicular do capim-marandu (p > 0,05). A massa do resíduo e sistema radicular, assim como a concentração de carboidratos não estruturais nesses órgãos de acúmulo, sofreram influência apenas do período de rebrota (p < 0,0001). Já a concentração de nitrogênio total no resíduo e nas raízes foi influenciada pela interação entre níveis de infestação e período de rebrota (p < 0,0001 e p = 0,0521).

[Severe intermittent claudication: PGE1 treatment. A 40-week registry, efficacy and costs]

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.

Lifetime post-traumatic stress symptoms are related to the health-related quality of life and severity of pain/fatigue in patients with fibromyalgia

OBJECTIVES

The aim of the present study was to investigate the impact of lifetime potentially traumatic events, including losses, and of post-traumatic stress symptoms on the severity of illness and health-related quality of life in patients with fibromyalgia (FM).

METHODS

Seventy patients with FM, diagnosed according to the American College of Rheumatology criteria, were consecutively enrolled at the Unit of Rheumatology of the University of Pisa, Italy. Assessments included: SCID-I/P; the Fibromyalgia Impact Questionnaire (FIQ) and the Medical Outcomes Study Short Form-36 Health Survey (MOS SF-36), for the severity of pain; the Health-Related Quality of Life (HRQoL); the Trauma and Loss Spectrum Self-Report (TALS-SR) life-time version.

RESULTS

The FIQ total score was related to the number of loss events (Domain I) and to symptoms of grief reactions (Domain II) and re-experiencing (Domain V) of the TALS-SR. The 'VAS fatigue' scores (FIQ) were significantly related to the TALS-SR symptoms of grief reactions (Domain II) and re-experiencing (Domain V). The Mental Component Summary and Bodily Pain scores of the MOS SF-36 were significantly related to all TALS-SR domains, the latter with the exception of the VIII (Arousal).

CONCLUSIONS

Our results corroborate the presence of a relationship between the lifetime exposure to potentially traumatic events, in particular loss events, and lifetime post-traumatic stress symptoms and the severity of illness and HRQoL in patients with FM.

Topical formulation of heparin is effective in reducing the symptoms of superficial venous thrombosis: a monocenter, observer-blind, placebo-controlled randomized study

AIM

The aim of the present, randomized, placebo controlled study was to assess the dose-dependent symptom reduction efficacy, safety and tolerability of heparin-spraygel (Viatromb 2.400 IU/g heparin spraygel) in patients with superficial vein thrombosis (SVT) of the lower limbs.

METHODS

A number of clinically relevant objectives; time to onset and intensity of symptoms' reduction reflected also by rescue medication consumption were considered and assessed.

RESULTS

Pain reduction between the two time-points (days 0 and 7) was significant within both treatment groups (active drug and placebo). However, subjects treated with active drug reported a mean pain reduction (VAS) of 76.21 mm (93.13% decrease); in subjects treated with placebo it was 50.36 (61.35%) mm (P<0.0001). The difference in pain reduction between the active drug and placebo groups was significant (P<0.05). The proportion of responders (subjects with at least 50%reduction in pain (VAS) on day 7 and day 14) was higher within subjects treated with Viatromb (P<0.05). The extension of erythema, evaluated by planimetry indicated a significantly higher reduction (day 0 to 7 and 0 to 14) in Viatromb-treated subjects in comparison with placebo. In the Viatromb group, the reduction in thrombus size was remarkable towards placebo (P<0.05). Reduction of edema and pain (VRS) had comparable time courses. Both investigator's and subject's global assessment of efficacy were significantly better with Viatromb. No adverse events or reactions were reported during the study and the follow up period.

CONCLUSION

Viatromb was significantly more effective than placebo in the symptomatic treatment of SVT.

Osteoporosis of the jaw. Product evaluation: mf Odontovis Calcium®

AIM

The aim of this study was to test mf Odondovis Calcium® as a food supplement in a 3-month product evaluation study measuring how the low jaw bone density, could be improved. The upper jaw density was tested with an ultrasound method, evaluating the grey scale median of the images (GSM).

METHODS

Seventy nine subjects were enrolled; 22 normal subjects (group A) and 57 with upper jaw osteoporosis (according to DEXA values). Patients were divided into 2 groups (group B and C, respectively 28 and 29 cases). These subjects were treated with what was considered the' best treatment' and in the group B only was added mf Odontovis Calcium®, consisting of calcium salts, Vitamin D and physiological modulators with antioxidant activity. This treatment continued for 3 months.

RESULTS

The GSM of osteoporotic patients was significantly lower in comparison with GSM in normal subjects. No changes were observed (between the inclusion and 3 month values) in normal subjects and minimal, non-significant changes were observed in control osteoporosis patients. Before-after treatment values of GSM in treatment patients showed a significant increase (P<0.022) at 3 months. The increase in GSM in these patients was significantly higher (P<0.05) in comparison with control patient with osteoporosis. The Tolerability of the product was very good and the compliance corresponded to 98%.

CONCLUSION

the jaw density in patients with osteoporosis is increased in only 3 months with supplementation with mf Odontovis Calcium®. Long-term clinical implications should be observed in more prolonged studies.

Gore external valve support for superficial saphenous vein incompetence: a 10-year, follow-up registry

AIM

This long-term (10-year) study evaluated the safety and efficacy of expanded polytetrafluoroethylene (ePTFE) external valve support (EVS) implants used for external valvuloplasty in the treatment of incompetence of the proximal long saphenous veins.

METHODS

During a 10-year follow-up, patients with superficial venous disease and venous hypertension due to pure superficial vein incompetence underwent an external valvuloplasty using an EVS with a PTFE suture. Forty-nine patients were included in the EVS group and 47 in the control group. Patients with superficial venous disease and venous hypertension due to pure superficial venous incompetence were randomised into two treatment groups. The first group was treated with what was considered "conventional treatment" (ligation or stripping) and the second with external valvuloplasty with EVS. This report deals with controls treated with ligation as only 6 cases (not mentioned in this report) were treated with stripping. There were no significant differences in the two groups concerning age, sex, or type of venous insufficiency. The procedures focused on only one single limb per patient.

RESULTS

46.9% of limbs treated with EVS developed varices in comparison with 73% in the control group. New surgical procedures (localized ligation) were needed in 32.6% of the EVS patients vs. 55.3% in controls. Sclerotherapy was used in 42% of the EVS patients vs. 72.34% in controls. At 10 years the SFJ was incompetent (reflux) in 2 EVS patients (4%); one after 5 years and one after 7 years. There was no incompetence at the level of the ligated junction in controls. There were 62 incompetent venous sites (1.26 per limb) in the EVS group vs. 96 new incompetent venous sites (2.04 per limb) in controls. In controls 10.63% of the limbs developed minor discolorations and signs due to mild CVI; none was observed in the EVS group. In all ESV implants there was full restoration of competence at 1 year.

CONCLUSION

EVS implants used to correct superficial venous incompetence at 10 years were well tolerated and produced good results on incompetence and on the evolution of varicose veins.

Potential role of curcumin phytosome (Meriva) in controlling the evolution of diabetic microangiopathy. A pilot study

AIM

The aim of the present study was to evaluate the improvement of diabetic microangiopathy in patients suffering from this condition since at least five years, and whose disease was managed without insulin.

METHODS

Curcumin, the orange pigment of turmeric, has recently received increasing attention because of its antioxidant properties, mediated by both direct oxygen radical quenching and by induction of anti-oxidant responses via Nrf2 activation. This aspect, combined with the beneficial effects on endothelial function and on tissue and plasma inflammatory status, makes curcumin potentially useful for the management of diabetic microangiopathy. To further evaluate this, Meriva, a lecithinized formulation of curcumin, was administered at the dosage of two tablets/day (1 g Meriva/day) to 25 diabetic patients for four weeks. A comparable group of subjects followed the best possible management for this type of patients.

RESULTS

All subjects in the treatment and control group completed the follow-up period; there were no dropouts. In the treatment group, at four weeks, microcirculatory and clinical evaluations indicated a decrease in skin flux (P<0.05) at the surface of the foot, a finding diagnostic of an improvement in microangiopathy, the flux being generally increased in patients affected by diabetic microangiopathy. Also, a significant decrease in the edema score (P<0.05) and a corresponding improvement in the venoarteriolar response (P<0.05) were observed. The PO2 increased at four weeks (P<0.05), as expected from a better oxygen diffusion into the skin due to the decreased edema. These findings were present in all subjects using Meriva, while no clinical or microcirculatory effects were observed in the control group.

CONCLUSION

Meriva was, in general, well tolerated, and these preliminary findings suggest the usefulness of this curcumin formulation for the management of diabetic microangiopathy, opening a window of opportunities to be evaluated in more prolonged and larger studies. The molecular mechanisms involved in the beneficial effects of curcumin on microcirculation and edema are also worth investigation.

Venoruton®: post thrombotic syndrome. Clinical improvement in venous insufficiency (signs and symptoms) with Venoruton®. A five-year, open-registry, efficacy study

AIM

This registry evaluation was conducted in post-thrombotic syndrome (PTS) patients (with a minimum five-year follow up). The study evaluated: 1) variations in peripheral edema with an analogue scoring system; 2) ankle circumference at the PTS limb in comparison with the normal contralateral limb.

METHODS

The difference was expressed in percent increase in circumference measured at the PTS limb; 3) other end-points were observed in a five-year follow-up that created a specific PTS registry. Subjects could follow a management system including: 1) compression; 2) compression and Venoruton® (1 g/day); 3) compression and Venoruton® (2 g/day).

RESULTS

The groups of patients with chronic venous insufficiency (CVI) resulted comparable. The occurrence of a new deep venous thrombosis (DVT) episode was considered a drop out. At five years there were four new DVTs (in 90 patients) in the compression group. There was one case (90 patients included) in the compression and HR (1 g) group and no DVT in group 3. The outcome in groups 2 and 3 was significantly better (0.05) than in group 1. The need for surgery or sclerotherapy (for larger varicose veins), the occurrence of lipodermatosclerosis and ulcerations were significantly lower in the HR groups with a better outcome in the higher dose group (P<0.05). The number of ulcerations were also significantly reduced in the HR groups. The difference in ulcerations was significantly better in the higher dose group in comparison with the other groups (P<0.05). The edema score was significantly reduced at five years in the HR groups (P<0.05) in comparison with the compression group. The higher dose resulted more effective in controlling edema. Both edema score and ankle circumference at five years were significantly lower (P<0.05) in the HR-treated groups with a significant decrease in edema score and ankle circumference in the higher dosage group.

CONCLUSION

The study confirms the long-term efficacy of HR in PTS, CVI patients. Controlling signs/symptoms and edema in CVI with HR prevents the most severe complications of CVI including lipodermatosclerosis and venous ulcerations. An early therapeutic program including exercise, risk factor controls, compression an edema-controlling treatment with HR is effective in decreasing the classic complications of PTS syndrome. The important restrictions and difficulties to the use of elastic stockings (in regions with warmer climates) are not applicable to HR that is well tolerated and can be used all the time alone or in association with compression.

Prevention of post thrombotic syndrome with Pycnogenol® in a twelve month study

AIM

Post-thrombotic syndrome is a common complication following deep vein thrombosis. The aim of this twelve month registry study was to compare the efficacy of compression stockings and per oral administration of Pycnogenol® standardized pine bark extract on the severity and incidence of post thrombotic syndrome signs and symptoms.

METHODS

One hundred fifty-six patients with a single, major episode of proximal deep vein thrombosis (DVT) were assigned to one of three groups receiving treatment with either compression stockings (group 1), Pycnogenol® (group 2) or the combination of both (group 3) over an investigational period of one year. The study evaluated treatment on edema using a scoring system, the ankle circumference, and the limb volume as ratio to the healthy contralateral limb.

RESULTS

Two new incidents of DVT occurred in the group of 55 patients wearing compression stockings between the third and sixth months, whereas no DVT cases occurred in the two other groups which took Pycnogenol®. The edema symptom score was gradually decreased in all three groups during the one year treatment period. Pycnogenol® was significantly more effective from six months onwards than compression stockings for relieving edema symptoms (P<0.05). Symptoms were more effectively reduced with the combination of Pycnogenol® and compression stockings than with the individual regimen alone (P<0.05). Limb volume and ankle circumference were likewise more effectively reduced with Pycnogenol® plus stockings than with compression stockings alone after six months. Ambulatory venous pressure progressively decreased in all three groups after twelve months treatment as compared to baseline. Compression stockings and Pycnogenol® were of comparable efficacy, there were no significant differences of ambulatory venous pressure between groups following twelve months treatment. Laser Doppler flowmetry at the dorsum of feet showed improved micro-circulation which was further demonstrated by increased pO2 and decreased pCO2. Importantly, none of the patients developed ulcerations during the observational period.

CONCLUSION

This study suggests that Pycnogenol® may have significant long-term protective efficacy for individuals following a thrombotic event. Moreover, Pycnogenol® appears to be at least as effective for post-thrombosis management as compression stockings, while the combination of both is superior. An important aspect is the patient compliance which was found to be much better in the Pycnogenol® group with two drop-outs due to non-medical reasons, whereas in the compression stockings group eighteen patients were lost to follow-up because wearing stockings at higher temperatures is bothersome.

rKv1.2 overexpression in the central medial thalamic area decreases caffeine-induced arousal

The voltage-gated potassium channel Kv1.2 belongs to the shaker-related family and has recently been implicated in the control of sleep profile on the basis of clinical and experimental evidence in rodents. To further investigate whether increasing Kv1.2 activity would promote sleep occurrence in rats, we developed an adeno-associated viral vector that induces overexpression of rat Kv1.2 protein. The viral vector was first evaluated in vitro for its ability to overexpress rat Kv1.2 protein and to produce functional currents in infected U2OS cells. Next, the adeno-associated Kv1.2 vector was injected stereotaxically into the central medial thalamic area of rats and overexpression of Kv1.2 was showed by in situ hybridization, ex vivo electrophysiology and immunohistochemistry. Finally, the functional effect of Kv1.2 overexpression on sleep facilitation was investigated using telemetry system under normal conditions and following administration of the arousing agent caffeine, during the light phase. While no differences in sleep profile were observed between the control and the treated animals under normal conditions, a decrease in the pro-arousal effect of caffeine was seen only in the animals injected with the adeno-associated virus-Kv1.2 vector. Overall, our data further support a role of the Kv1.2 channel in the control of sleep profile, particularly under conditions of sleep disturbance.
