Untangling the relationship between fat distribution, nutritional status and Parkinson's disease severity.

Background: Parkinson's disease (PD) is responsible for significant changes in body composition.

Aims: We aimed to test the association between PD severity and fat distribution patterns, and to investigate the potential modifier effect of nutritional status in this association.

Methods: We enrolled 195 PD subjects consecutively admitted to a university geriatric day hospital.

Association of Pisa Syndrome With Mortality in Patients With Parkinson's Disease.

Objectives: In Parkinson's disease, Pisa syndrom (PS) has been associated with disease stage and severity, combined treatment with levodopa and dopamine agonists, gait disorders, and comorbidities. Some forms of PS are potentially reversible; nevertheless, little is known about the impact of this syndrome on survival.

Design: Prospective study with a median follow-up of 2 years.

Prevalence of Impulsive-Compulsive Symptoms in Elderly Parkinson's Disease Patients: A Case-Control Study.

Background: Impulse-control disorders (ICDs) are frequently described in patients with Parkinson's disease (PD), particularly among those treated with dopaminergic medications, but data on the prevalence of ICDs in elderly populations are lacking.

Objective: The aim of this study was to estimate the prevalence of ICDs by using an Italian validation of the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease (QUIP) and to identify associated sociodemographic and clinical factors in a sample of elderly PD patients and in a control group of similarly aged healthy volunteers.

Methods: Using the United Kingdom Parkinson's Disease Society Brain Bank diagnostic criteria, we included 115 consecutive PD and 105 healthy controls.

Sarcopenia in Parkinson Disease: Comparison of Different Criteria and Association With Disease Severity.

Objectives: In Parkinson disease (PD), sarcopenia may represent the common downstream pathway that from motor and nonmotor symptoms leads to the progressive loss of resilience, frailty, and disability. Here we (1) assessed the prevalence of sarcopenia in older adults with PD using 3 different criteria, testing their agreement, and (2) evaluated the association between PD severity and sarcopenia.

Design: Cross-sectional, observation study.

Slow or fast viral load decay as a predictor of residual viremia level in HIV-infected patients undergoing successful first-line cART.

Persistent residual viremia (RV) has been demonstrated in 70-90% of patients under successful cART. We analyzed the RV trend during the first year following cART-induced virological suppression (VS; HIVRNA <50 copies/ml) to identify predictors of achievement and maintenance of ultra-deep RV suppression (URVS; HIV-RNA <5 copies/ml) in 60 naïve patients. These patients were aligned at the time of reaching VS and were longitudinally tested with an ultrasensitive HIV-RNA assay.

The role of cognitive reserve in cognitive aging: what we can learn from Parkinson's disease.

Parkinson's disease (PD) typically occurs in elderly people and some degree of cognitive impairment is usually present. Cognitive reserve (CR) theory was proposed to explain the discrepancy between the degree of brain pathologies and clinical manifestations. We administered a comprehensive neuropsychological battery to 35 non-demented participants affected by PD.

Use of ACE-inhibitors and falls in patients with Parkinson's disease.

Falls represent a major concern in patients with Parkinson's disease (PD); however, currently acknowledged treatments for PD are not effective in reducing the risk of falling. The aim was to assess the association of use of ACE-inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) with falls among patients with PD. We analysed data of 194 elderly with PD attending a geriatric Day Hospital.

Assessing and Measuring Chronic Multimorbidity in the Older Population: A Proposal for Its Operationalization.

Background: Although the definition of multimorbidity as "the simultaneous presence of two or more chronic diseases" is well established, its operationalization is not yet agreed. This study aims to provide a clinically driven comprehensive list of chronic conditions to be included when measuring multimorbidity.

Methods: Based on a consensus definition of chronic disease, all four-digit level codes from the International Classification of Diseases, 10th revision (ICD-10) were classified as chronic or not by an international and multidisciplinary team.

Impact of disease duration and cardiovascular dysautonomia on hypertension in Parkinson's disease.

The authors evaluated the association of Parkinson's disease (PD) duration with hypertension, assessed by office measurements and 24-hour (ambulatory) monitoring, in 167 patients. Hypertension was evaluated through both office and ambulatory blood pressure (BP) measurements. Among participants (mean age 73.

Association of metabolic syndrome with falls in patients with Parkinson's disease.

Background & Aims: Falls are a major threat for patients with Parkinson's disease, as they are associated with higher risk of morbidity, loss of functional ability, institutionalization, and mortality. Metabolic syndrome (MetS) is associated with poorer physical performance in middle age, but its impact in the older and frailer subjects is unclear. The present study aimed at assessing the association of MetS with falls in patients with Parkinson's disease.

Evaluation of the Aptima(®) HIV-1 Quant Dx assay for HIV-1 RNA viral load detection and quantitation in plasma of HIV-1-infected individuals: A comparison with Abbott RealTime HIV-1 assay.

The Hologic Aptima(®) HIV-1 Quant Dx assay (Aptima HIV) is a real-time transcription-mediated amplification method CE-approved for use in diagnosis and monitoring of HIV-1 infection. The analytical performance of this new assay was compared to the FDA-approved Abbott RealTime HIV-1 (RealTime). The evaluation was performed using 220 clinical plasma samples, the WHO 3rd HIV-1 International Standard, and the QCMD HIV-1 RNA EQA.

Association of depressive symptoms with circadian blood pressure alterations in Parkinson's disease.

To assess whether among patients with Parkinson's disease (PD) depression, a common non-motor symptom associated with reduced survival, is associated with cardiovascular dysautonomia. We enrolled 125 subjects with PD consecutively admitted to a geriatric day hospital. All participants underwent comprehensive evaluation, fasting blood sampling, and 24-h ambulatory blood pressure monitoring.

Celiac disease in subjects with type 1 diabetes mellitus: a prevalence study in western Sicily (Italy).

The association between celiac disease and type 1 diabetes mellitus is well known. Up to now, celiac disease prevalence in children and adults with type 1 diabetes in Sicily has not been reported. The aim of this study was to assess the prevalence of celiac disease in patients with type 1 diabetes mellitus who come from a defined geographical area in western Sicily and to investigate the clinical features of these subjects.

Graves' disease in subjects with type 1 diabetes mellitus: a prevalence study in western Sicily (Italy).

Objective: To assess the prevalence of Graves' disease in patients with type 1 diabetes mellitus all coming from a defined geographical area (western Sicily-Italy) and to investigate the clinical features of these subjects.

Methods: The records of 470 consecutive patients with type 1 diabetes mellitus referred in a 5-year period were analyzed.

Results: During the period of the survey, out of 470 patients with type 1 diabetes, 14 (3%) had a previous diagnosis of Graves' disease.

Methods: Astrovirus was detected by reverse transcriptase-PCR; routine diagnostic tests for Rotavirus, Adenovirus, and common bacterial pathogens were carried out on all samples.

Results: Of the 460 children with nosocomial diarrhea, 23 harbored Astrovirus (5%).

Anti-Invasive Activity of Bovine Lactoferrin against Listeria monocytogenes.

We have investigated the possible role of bovine lactoferrin in protecting the intestinal epithelium from bacterial infections, using as an in vitro model enterocyte-like cell lines HT-39 and Caco-2 infected with a food-borne pathogen, Listeria monocytogenes . When infection occurred in the presence of 1 mg/ml of bovine lactoferrin, in the form of apolactoferrin or iron- or manganese-saturated forms, the adhesion of bacteria to eukaryotk cells was unaffected, but the number of internalized bacteria was reduced by 42- to 125-fold. The possibility of a toxic effect of lactoferrin was excluded, because bovine lactoferrin was used at nonbactericidal and noncytotoxic concentrations.
