Effect of Global Postural Rehabilitation program on spatiotemporal gait parameters of parkinsonian patients: a three-dimensional motion analysis study

The aim of the present study was to evaluate the effects of a Global Postural Rehabilitation (GPR) program on motor symptoms and gait parameters of patients with Parkinson’s disease (PD) by means of three-dimensional motion analysis study. Ten subjects with clinical diagnosis of PD were enrolled (study group). Age-, sex- and disease duration-matched PD patients were recruited as a control group (no treatment). Three-dimensional motion analysis was conducted by means of a stereophotogrammetric system. After basal evaluation, the study group underwent a specific rehabilitation program consisting of individual 40?min GPR daily sessions, 3?days a week for 4 consecutive weeks. Neurological status and spatiotemporal gait parameters of the two groups were evaluated at study entry (t ₀), at 4?weeks (t ₁, end of rehabilitation protocol) and at 8 and 12?weeks (t ₂ and t ₃, follow-up evaluation). At baseline evaluation, the two groups did not differ in clinical features and gait parameters. At the end of rehabilitation protocol (t ₁) and at follow-up evaluation (t ₂ and t ₃), a significant improvement in temporal gait parameters and UPDRS scores was observed in all treated patients as compared to baseline and controls. Our preliminary findings showed that significant improvements in mobility and gait parameters of PD patients can be obtained through GPR treatment, with a parallel improvement in clinical status. Quantitative analysis of gait pattern can be considered a useful tool to assess the efficacy of rehabilitation interventions in patients affected by PD.     

Effect of litter quality on foot pad dermatitis,hock burns and breast blisters in broiler breeders during the production period

Foot pad dermatitis and hock burn lesions are a form of contact dermatitis, a condition affecting skin areas in contact with unsuitable or irritating material. Contact dermatitis is a common problem, reducing the welfare of broilers, and is believed to also affect broiler breeders. However, there is very little research on contact dermatitis in breeders. This study followed the severity of foot pad lesions in broiler breeders throughout the production period. At slaughter the presence of hock burns and breast blisters was also determined. In addition, changes in litter condition over time and the impact of litter quality on foot pads were evaluated. The study was performed on 10 broiler breeder farms, including altogether 18 flocks. Foot pads of 100 hens per flock were assessed at the end of rearing period, three times during the production period, and at slaughter. Foot pad and hock lesions, as well as litter condition were scored on a 5-point scale. Litter quality was evaluated as pH, moisture and ammonia content. The condition of foot pads deteriorated towards slaughter age, with the occurrence of severe lesions reaching a maximum of 64% on average at slaughter. Hock lesions and breast blisters were rare. The litter layer became drier over time. Although poorer litter condition and wetness influenced foot pad health negatively, the effect on severe lesions was not significant. We also observed a negative effect on foot pad condition of larger slat areas. In conclusion, maintaining good litter quality alone is not enough to ensure healthy foot pads in broiler breeders.     

Liposomes for Topical Use: A Physico-Chemical Comparison of Vesicles Prepared from Egg or Soy Lecithin

Developments in nanotechnology and in the formulation of liposomal systems provide the opportunity for cosmetic dermatology to design novel delivery systems. Determination of their physico-chemical parameters has importance when developing a nano-delivery system. The present study highlights some technological aspects/characteristics of liposomes formulated from egg or soy lecithins for topical use. Alterations in the pH, viscosity, surface tension, and microscopic/macroscopic appearance of these vesicular systems were investigated. The chemical composition of the two types of lecithin was checked by mass spectrometry. Caffeine, as a model molecule, was encapsulated into multilamellar vesicles prepared from the two types of lecithin: then zeta potential, membrane fluidity, and encapsulation efficiency were compared. According to our observations, samples prepared from the two lecithins altered the pH in opposite directions: egg lecithin increased it while soy lecithin decreased it with increased lipid concentration. Our EPR spectroscopic results showed that the binding of caffeine did not change the membrane fluidity in the temperature range of possible topical use (measured between 2 and 50 °C). Combining our results on encapsulation efficiency for caffeine (about 30% for both lecithins) with those on membrane fluidity data, we concluded that the interaction of caffeine with the liposomal membrane does not change the rotational motion of the lipid molecules close to the head group region. In conclusion, topical use of egg lecithin for liposomal formulations can be preferred if there are no differences in the physico-chemical properties due to the encapsulated drugs, because the physiological effects of egg lecithin vesicles on skin are significantly better than that of soy lecithin liposomes.     

Clinical outcomes and costs for patients with type 2 diabetes mellitus initiating insulin therapy in Greece: Two-year experience from the INSTIGATE study

AimsTo evaluate the quality of metabolic control, clinical outcomes, resource costs, and quality of life among patients with type 2 diabetes mellitus (T2DM), who initiated insulin for the first time as part of routine clinical practice.MethodsThe INSTIGATE study is a prospective, multicentric, observational study of patients initiating insulin treatment. This sub-cohort analysis focuses on Hellenic outcomes.ResultsAt baseline, 263 Greek patients were enrolled just before initiating insulin for the first time. At the 6-month visit, 237 patients (90.1%) remained and consented to an additional 18-month observation period. In these 237 extension patients, over the 24-month post-initiation period, HbA1c (mean(SD)) decreased from 9.7%(1.6%) to 7.1%(0.9%) and body weight and BMI increased (+3(6) kg and +1.1(2.2) kg/m², respectively). At each post-baseline visit approximately one in five patients reported ≥1 episodes of hypoglycaemia in the preceding 3–6 months. Median total costs fluctuated from 438€ at baseline to 538€ up to 6 months and 451€ at 24 months; mean costs were 496(383)€, 573(276)€ and 485(247)€, respectively.ConclusionsIn this cohort, insulin treatment seems to be effective with little long-term impact on cost. Findings should be interpreted in the context of an observational study.     

Transcatheter arterial chemoembolization (TACE) in treatment of hepatocellular carcinoma

BACKGROUND/AIMS: Substantial differences about the efficacy of transcatheter arterial chemoembolization for the treatment of hepatocellular carcinoma are reported in literature. This probably depends on the fact that in each single study, different patient selection criteria, type of epidemiological approach, end points adopted and kind of technical approach were used. This study aims to evaluate the efficacy of segmental transcatheter arterial chemoembolization in amelioring patient survival and to determine which patients might really benefit from this treatment. METHODOLOGY: To achieve our goals 193 consecutive patients (110 treated and 83 untreated) were studied. They were selected in the same period of time and matched as far as their demographic and clinical characteristics. RESULTS: Our results demonstrate that both in treated and control patients, Child class, alpha-fetoprotein and tumor diameter significantly influenced survival, resulting important prognostic factors. Transcatheter arterial chemoembolization significantly ameliorated survival in treated patients compared to controls (p < 0.0001). CONCLUSIONS: Transcatheter arterial chemoembolization significantly ameliorates survival in patients with hepatocellular carcinoma. However, the presence of large tumors producing high alpha-fetoprotein levels in patients with advanced Child class should discourage treatment.     

Association of Long-Term Diet Quality with Hippocampal Volume: Longitudinal Cohort Study

BACKGROUND

Diet quality is associated with brain aging outcomes. However, few studies have explored in humans the brain structures potentially affected by long-term diet quality. We examined whether cumulative average of the Alternative Healthy Eating Index 2010 (AHEI-2010) score during adult life (an 11-year exposure period) is associated with hippocampal volume.

Red cell transfusion in paediatric patients with thalassaemia and sickle cell disease: Current status,challenges and perspectives

Notwithstanding the high safety level of the currently available blood for transfusion and the decreasing frequency of transfusion-related complications, administration of labile blood products to paediatric patients still poses unique challenges and considerations. The incidence of thalassaemia and sickle cell disease in the paediatric population may be high enough under specific racial and geographical contexts. Red cell transfusion is the cornerstone of β-thalassaemia treatment and one of the most effective ways to prevent or correct specific acute and chronic complications of sickle cell disease. However, this life-saving strategy comes with its own complications, such as additional iron overload, alloimmunization and haemolytic reactions, among others. In paediatrics, the dependency of the transfusion outcome upon disease and other recipient characteristics is more prominent compared with the adults, owing to differences in developmental maturity and physiology that render them more susceptible to common risks, exacerbate the host response to transfused cells, and modify the type or the clinical severity of the transfusion-related morbidity. The adverse branch of red cell transfusion is likely the overall effect of several factors acting synergistically to shape the clinical phenotype of this therapy, including inherent donor/blood unit variables, like antigenicity, red cell deformability and extracellular vesicles, as well as recipient variables, such as history of alloimmunization and inflammation level at time of transfusion. This review focuses on paediatric patients with β-thalassaemia and sickle cell disease as a recipient group with distinct transfusion-related characteristics, and introduces new concepts for consideration, not adequately studied and elucidated so far.
