Community-based group exercise for persons with Parkinson disease: a randomized controlled trial.

The purpose of this study was to compare group boxing training to traditional group exercise on function and quality of life in persons with Parkinson disease (PD). A convenience sample of adults with PD (n = 31) were randomly assigned to boxing training or traditional exercise for 24-36 sessions, each lasting 90 minutes, over 12 weeks. Boxing training included: stretching, boxing (e.g. lateral foot work, punching bags), resistance exercises, and aerobic training. Traditional exercise included: stretching, resistance exercises, aerobic training, and balance activities. Participants were tested before and after completion of training on balance, balance confidence, mobility, gait velocity, gait endurance, and quality of life. The traditional exercise group demonstrated significantly greater gains in balance confidence than the boxing group (p < 0.025). Only the boxing group demonstrated significant improvements in gait velocity and endurance over time with a medium between-group effect size for the gait endurance (d = 0.65). Both groups demonstrated significant improvements with the balance, mobility, and quality of life with large within-group effect sizes (d ≥ 0.80). While groups significantly differed in balance confidence after training, both groups demonstrated improvements in most outcome measures. Supporting options for long-term community-based group exercise for persons with PD will be an important future consideration for rehabilitation professionals.
Hepatitis B and immigrants: a SIMIT multicenter cross-sectional study

The continuing migration of individuals from geographic areas with high/medium endemicity has determined the arrival of new chronic hepatitis B virus (HBV) carriers in Italy. The magnitude of this phenomenon and clinical/virological features of HBsAg-positive migrants remain not very well defined. To evaluate the proportion of HBsAg-positive immigrants enrolled in this multicenter Società Italiana di Malattie Infettive e Tropicali (SIMIT) cross-sectional study and to compare the characteristics of chronic hepatitis B infection in migrants to those of Italian carriers. From February 1 to July 31 2008, anonymous data were obtained from all HBsAg-positive patients aged ≥18 years observed at 74 Italian centers of infectious diseases. Of the 3,760 HBsAg-positive subjects enrolled, 932 (24.8 %) were immigrants, with a prevalent distribution in central to northern Italy. The areas of origin were: Far East (37.1 %), Eastern Europe (35.4 %), Sub-Saharan Africa (17.5 %), North Africa (5.5 %), and 4.5 % from various other sites. Compared to Italian carriers, migrants were significantly younger (median age 34 vs. 52 years), predominantly female (57.5 vs. 31 %), and most often at first observation (incident cases 34.2 vs. 13.3 %). HBeAg-positives were more frequent among migrants (27.5 vs. 14 %). Genotype D, found in 87.8 % of Italian carriers, was present in only 40 % of migrants, who were more frequently inactive HBV carriers, with a lower prevalence of chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). Only 27.1 % of migrants received antiviral treatment compared to 50.3 % of Italians. Twenty-five percent of all HBV carriers examined at Italian centers was composed of immigrants with demographic, serological, and virological characteristics that differed from those of natives and appeared to have an inferior access to treatment.
Safety and efficacy of an “enhanced recovery after surgery” protocol for patients undergoing colon cancer surgery: a multi-institutional controlled study

The aim of this multi-institutional study was to prospectively evaluate the safety and efficacy of an enhanced recovery after surgery (ERAS) protocol for colonic surgery. The subjects of this study were 320 patients with an American Society of Anesthesiologists (ASA) grade I or II physical status. Patients underwent elective open or laparoscopic colonic resection or high anterior resection between April 2011 and January 2014 at one of six institutions. Three hospitals implemented an ERAS protocol (n = 159), and three administered conventional care (n = 161). The primary outcome measure was the surgical complication rate. Most operations, irrespective of group, were performed laparoscopically. The incidence of a surgical complication was 17.0 % in the ERAS group vs. 16.1 % in the conventional group (P = 0.842), in which several non-surgical complications also arose. Oral food intake was implemented earlier for the ERAS group vs. the conventional group, after a median (range) of 1 (1–31) vs. 3 (1–9) days for the ERAS vs. conventional care groups, respectively (P < 0.001). The median length of postoperative hospital stay was reduced by 5.5 days for the ERAS group, being 8.5 (5–41) vs. 14 (7–56) days for the ERAS vs. conventional care groups, respectively (P < 0.001). This multi-institutional controlled study clearly demonstrated that an ERAS protocol was efficient, without increasing the complication risk.
Early pressure dressing for the prevention of subdural effusion secondary to decompressive craniectomy in patients with severe traumatic brain injury.

This study was performed to investigate the effect of early pressure dressing on the prevention of postoperative subdural effusion secondary to decompressive craniectomy (DC) in patients with severe traumatic brain injury (STBI). Patients with STBI who had undergone DC for refractory increased intracranial pressure between January 2008 and December 2011 (n = 169) were randomly divided into early pressure dressing (n = 82) and control (n = 87) groups. Early pressure dressing with an elastic bandage or general wrapping (control treatment) was applied 7 to 10 days after DC. Patients' age, sex, preoperative Glasgow Coma Scale score, incidence rate of subdural effusion, hospitalization time, and postoperative Glasgow Outcome Scale score were compared between groups. Intracranial pressure was measured immediately before and on the day after pressure dressing. No significant difference in age, sex, preoperative Glasgow Coma Scale score, or postoperative Glasgow Outcome Scale score was observed between groups (P > 0.05). Subdural effusion incidence rates were significantly lower in the early pressure dressing group than those in the control group (χ² = 5.449, P = 0.021), and a larger proportion of patients in the early pressure dressing group was hospitalized for 30 days or less (χ² = 5.245, P = 0.027). Early pressure dressing 7 to 10 days after DC, which is a noninvasive, simple procedure, reduced the incidence rate of subdural effusion and shortened hospitalization time after DC for STBI.
Hook plate fixation for acromioclavicular joint separations restores coracoclavicular distance more accurately than PDS augmentation, however presents with a high rate of acromial osteolysis

Hook plate fixation of acromioclavicular (AC) joint separations carries the disadvantage of compulsory implant removal, occasional implant fatigue and secondary loss of reduction. This study compares the clinical and radiological outcome of a new polyaxial angular stable hook plate (HP) with absorbable polydioxansulfate (PDS) sling. Between 2002 and 2009, out of a consecutive series of 81 patients with symptomatic Rockwood type V lesions 52 patients received clinical and radiographic follow-up (HP: n = 27; PDS: n = 25). HP patients were prospectively analyzed and retrospectively compared with the PDS group. Radiological follow-up included comparative coraco- and acromioclavicular distance (CCD/ACD) measurements as percentage of the uninjured shoulder. For clinical follow-up a standardized functional shoulder assessment with Constant Score, DASH Score, Taft Score and a self-report questionnaire including the visual analog scale (VAS) was carried out. Direct postoperative radiographs showed an overcorrection of CCD in the HP group (−4.4% of the uninjured side) and failure of anatomic correction in the PDS group (+11.0%). After implant removal, CCD increased in the HP group extensively to 16.7% (overall loss of reduction: 21.1%) and 23.9% in the PDS group. Redisplacement (100% increase of CCD) occurred in five cases (HP: 2, PDS: 3) and partial loss of reduction in four cases of each group. Comparing functional results no differences could be seen between both the groups (Constant-Score HP: 91.2 points, PDS: 94.6 points; Taft-Score HP: 9.4 points, PDS: 10.0 points). The DASH-Score revealed better results for PDS group (3.4 points, HP: 8.0 points). Signs of acromial osteolysis appeared in five cases (18.5%) in HP group. There was no case of implant failure. The X-rays of six patients (HP: 4, PDS: 2) showed AC-joint-osteoarthritis. Hook plate fixation employing a polyaxial angular stable plate finally restores the coracoclavicular distance more accurately than augmentation with a PDS sling. Although in HP group no implant failure occurred, major disadvantages are initial overcorrection and acromial osteolysis. Both have no influence on final functional results.
Recurrence of atrial fibrillation after internal cardioversion of persistent atrial fibrillation: prognostic importance of electrophysiologic parameters.

The purpose of this study was to determine whether the extent of atrial electrical remodeling affects the recurrence of atrial fibrillation (AF) after cardioversion of persistent AF (PAF).



Internal atrial cardioversion was performed in 47 patients with PAF. The right atrial monophasic action potential duration (RA-MAPD) at pacing cycle lengths (PCLs) of 800-300 ms and P wave signal-averaged electrocardiogram were recorded after cardioversion. Bepridil (150-200 mg/day) and carvedilol (10 mg/day) were administered to all patients after cardioversion. Of the 47 patients, 20 had recurrent AF within 3 months. No relation was observed between age, left atrial dimension, left ventricular ejection fraction, and AF recurrence. The AF duration was significantly longer (p<0.05) and RA-MAPD at PCLs of 800 to 300 ms were significantly shorter (p<0.05) in patients with AF recurrence than in those without recurrence. The mean slope of the RA-MAPD for PCLs between 600 and 300 ms did not differ between the patients with and without AF recurrence. The filtered P-wave duration (FPD) was significantly longer in the patients with AF recurrence than in those without (p<0.05). Multivariate analysis also showed that the RA-MAPD at a PCL of 300 ms and FPD were predictors of AF recurrence (RAMAPD: p=0.038; FPD: p=0.052).



These results suggest that electrical remodeling related to the repolarization and depolarization may be the main contributors to early AF recurrence after cardioversion under the administration of bepridil and carvedilol.
[Magnitude and characteristics of residual lipid risk in patients with a history of coronary revascularization: the ICP-bypass study].

Residual lipid risk has been defined as the excess of cardiovascular events observed in patients with adequate control of low-density lipoprotein cholesterol and has been mainly attributed to high-density lipoprotein cholesterol and triglycerides. The aim of our study was to describe the clinical features and the magnitude and characteristics associated with residual lipid risk in patients with a history of coronary revascularization.



Multicenter, observational, cross-sectional study of patients with a history of coronary revascularization. Residual lipid risk was defined as the presence of high-density lipoprotein cholesterol <40 mg/dL and/or triglycerides >150 mg/dL in patients with low-density lipoprotein cholesterol <100 mg/dL.



We included 2292 patients with a mean age of 65.5 (12.4) years; 94.1% were receiving no statin therapy and 4.8% no lipid therapy. Statin-only therapy (74%) was the most common strategy, followed by combination with ezetimibe (17%). The prevalence of high-density lipoprotein cholesterol <40 mg/dL was 35.8%, hypertriglyceridemia 38.9%, and low-density lipoprotein cholesterol >100 mg/dL 44.9%; the residual lipid risk group included 29.9% of all patients. This patient group had a similar clinical profile except for slightly lower mean age, higher incidence of diabetes, and higher proportion of men. Multivariate analysis identified positive associations of diabetes and male sex with residual lipid risk; current smoking, male sex, and fibrate therapy were associated with high-density lipoprotein cholesterol <40 mg/dL; current smoking, abdominal obesity, and fibrate therapy were associated with hypertriglyceridemia.



In daily clinical practice, almost one-third of patients with a history of coronary revascularization have low-density lipoprotein cholesterol <100 mg/dL plus low high-density lipoprotein cholesterol and/or hypertriglyceridemia, a concept known as residual lipid risk.
Absence of Bladder Outlet Obstruction Is an Independent Risk Factor for Prostate Cancer in Men Undergoing Prostate Biopsy

The purpose of this study was to investigate the relationship between bladder outlet obstruction (BOO) and the risk of being diagnosed with prostate cancer (PCa).Study population consisted of 2673 patients scheduled for the first prostate biopsy (PBx). All patients underwent uroflowmetry before PBx; those with a peak flow rate (PFR) <10 mL/s were considered to have BOO.The incidence of PCa was 41.3% (1104/2673) in the overall population and 34.1% (659/1905) in patients with serum prostate-specific antigen (PSA) ≤ 10 ng/mL. Univariate and multivariate logistic regression analyses showed that patients with BOO had a significantly (P < 0.0001) lower risk than those without BOO of being diagnosed with PCa (33.1% vs 66.9% in the overall population; 30% vs 70% in patients with PSA ≤ 10 ng/mL). As the presence of BOO was significantly correlated to a large prostate volume, another independent predictor of PBx outcome, we tested whether these parameters could be used to identify, in the subset of patients with PSA≤10 ng/mL, those who could potentially be spared from a PBx. If we would have not biopsied patients with BOO and prostate volume ≥60 mL, 14.5% of biopsies could have been avoided while missing only 6% of tumors. Only 10% of the tumors that would have been missed were high-risk cancers.In conclusion, in men undergoing PBx, the absence of BOO, as determined by a PFR ≥10 mL/s, is an independent risk factor for PCa. Our study provides ground for this simple, noninvasive, objective parameter being used, alone or in combination with prostate volume, in the decision-making process of men potentially facing a PBx.
Relationship between fluid intelligence and ability to benefit from cognitive-behavioural therapy in older adults: a preliminary investigation.

The aim of this study was to conduct a preliminary evaluation of the hypothesis that fluid intelligence in older adults is associated with the ability to benefit from cognitive-behavioural therapy (CBT), but unrelated to the ability to benefit from non-directive supportive counselling (SC).



A sample of 32 older adults who had completed a randomized controlled trial course of either CBT (N = 16) or SC (N = 16) for anxiety disorders took part in the study. The Raven's Coloured Progressive Matrices (RCPM) test was used to assess fluid intelligence. The Beck Anxiety Inventory change scores between pre-treatment and post-treatment were used as an index of ability to benefit from therapy. A measure of depressive symptomatology was also administered to control statistically for the effects of depression on intellectual functioning.



The results for the SC group showed a significant and positive association between fluid intelligence scores and anxiety change scores, such that older adults with higher levels of fluid intelligence demonstrated the most benefit from this intervention. In contrast, there was no significant association between level of fluid intelligence and ability to benefit from therapy in the CBT group.



CBT for anxiety disorders is suitable for older adults, irrespective of their fluid intelligence, while the nature of SC may render it more sensitive to level of fluid intelligence.
The Value of Postoperative Parathyroid Hormone Levels in Predicting the Need for Long-Term Vitamin D Supplementation after Total Thyroidectomy

Few studies have examined the need for vitamin D supplementation after total thyroidectomy. This study examines the role of postoperative day (POD) 1 serum calcium and parathyroid hormone (PTH) levels in predicting the need for long-term vitamin D supplementation after total thyroidectomy. A retrospective, single institutional study of patients who underwent total thyroidectomy between January 2007 and December 2008 was performed. Data collected included extent of surgery, final pathology, postoperative calcium (mg/dl) and PTH (pg/ml) values, and duration of vitamin D supplementation. Patients were divided into 4 groups based on POD1 PTH values: group 1 (<5.0); group 2 (5.0–10); group 3 (10.1–20); and group 4 (>20). Of the 104 patients, 26 were in group 1, 12 in group 2, 18 in group 3, and 48 in group 4, with median PTH values of <2.5, 8.2, 14.1, and 30 pg/ml, respectively. All 7 (7%) patients who required vitamin D supplementation >1 month were in group 1. The positive predictive value of POD1 PTH <5.0 in predicting supplementation >1 month was 27% (sensitivity 100%, specificity 80%). Seventy-eight patients had a POD1 PTH level ≥5, and none required vitamin D supplementation >1 month (100% negative predictive value). The positive predictive value of various POD1 calcium thresholds (<7.5, <8.0, and <8.5 mg/dl) was 17, 14, and 15%, respectively. Postoperative PTH levels better predict long-term hypocalcemia requiring vitamin D supplementation than serum calcium levels. A PTH level ≥5.0 may identify patients who can be safely discharged without routine vitamin D supplementation.
Comparison of three manual coccydynia treatments: a pilot study.

A prospective pilot study with independent assessment and a 2-year follow-up period was conducted.



To compare and assess the efficacy of three manual coccydynia treatments, and to identify factors predictive of a good outcome.



Various manual medicine treatments have been described in the literature. In an open study, the addition of manipulation to injection treatment produced a 25% increase in satisfactory results. Dynamic radiographs of the coccyx allow breakdown of coccydynia into four etiologic groups based on coccygeal mobility: luxation, hypermobility, immobility, and normal mobility. These groups may respond differently to manual treatments.



The patients were randomized into three groups, each of which received three to four sessions of a different treatment: levator anus massage, joint mobilization, or mild levator stretch. Assessment with a visual analog scale was performed by an independent observer at 7 days, 30 days, 6 months, and 2 years.



The results of the manual treatments were satisfactory for 25.7% of the cases at 6 months, and for 24.3% of the cases at 2 years. The results varied with the cause of the coccydynia. The patients with an immobile coccyx had the poorest results, whereas those with a normally mobile coccyx fared the best. The patients with luxation or hypermobility had results somewhere between these two rates. Levator anus massage and stretch were more effective than joint mobilization, which worked only for patients with a normally mobile coccyx. Pain when patients stood up from sitting and excessive levator tone were associated with a good outcome. However, none of the results was significant because of the low success rate associated with manual treatment.



There is a need for a placebo-controlled study to establish conclusively whether manual treatments are effective. This placebo must be an external treatment. A sample size of 190 patients would be required for 80% confidence in detecting a difference.
Filgrastim-mobilized peripheral blood progenitor cells versus bone marrow transplantation for treating leukemia: 3-year results from the EBMT randomized trial.

Allogeneic peripheral blood progenitor cells (PBPC) are now widely used as the source of hematopoietic stem cells for transplantation. However, it is still not clear which patients should receive mobilized PBPC or bone marrow cells to reconstitute hematopoiesis after myeloablative conditioning. The aim of this study is to present 3-year-follow-up data on outcome (incidence and severity of chronic graft-versus-host disease (GVHD), overall survival (OS) and leukemia-free survival (LFS) after a PBPC transplant (PBPCT) or a bone marrow transplant (BMT).



Data on 350 patients with leukemia were collected in a multicenter, randomized study initiated by the EBMT. The patients were randomized to receive filgrastim-mobilized PBSCT or BMT from an HLA-identical donor.



At a median follow-up of 3 years, significantly more patients transplanted with PBPC than with bone marrow developed chronic GVHD (73% vs 55%, p=0.003) and extensive chronic GvHD (36% vs 19%, p=0.002). The higher incidence and greater severity of chronic GvHD had little impact on the patient's performance status or survival. OS was 58% for PBPCT recipients versus 65% among those undergoing BMT. LFS was 56% for PBPCT recipients versus 60% for BMT recipients.



Patients transplanted with PBPC from an HLA-identical sibling develop more chronic GvHD than those transplanted with bone marrow, but the final impact of this difference is unclear. Longer follow-up is necessary to characterize the impact of chronic GvHD on quality of life, leukemia-free survival and overall survival.
Efficacy of IP 6 + inositol in the treatment of breast cancer patients receiving chemotherapy : prospective , randomized , pilot clinical study

Prospective, randomized, pilot clinical study was conducted to evaluate the beneficial effects of inositol hexaphosphate (IP6) + Inositol in breast cancer patients treated with adjuvant therapy.  Patients with invasive ductal breast cancer where polychemotherapy was indicated were monitored in the period from 2005-2007. Fourteen patients in the same stage of ductal invasive breast cancer were involved in the study, divided in two randomized groups. One group was subjected to take IP6 + Inositol while the other group was taking placebo. In both groups of patients the same laboratory parameters were monitored. When the treatment was finished, all patients have filled questionnaires QLQ C30 and QLQ-BR23 to determine the quality of life.  Patients receiving chemotherapy, along with IP6 + Inositol did not have cytopenia, drop in leukocyte and platelet counts. Red blood cell counts and tumor markers were unaltered in both groups. However, patients who took IP6 + Inositol had significantly better quality of life (p = 0.05) and functional status (p = 0.0003) and were able to perform their daily activities.  IP6 + Inositol as an adjunctive therapy is valuable help in ameliorating the side effects and preserving quality of life among the patients treated with chemotherapy.
