Background Orthostatic hypotension (OH) is frequent in patients with Parkinson disease (PD) and can occur with or without symptoms. Pharmacological treatments are effective but often exacerbate supine hypertension. Guidelines exist for the diagnosis but not for the treatment of OH. We examined the relationship between blood pressure and symptoms in a cohort of PD patients with the goal of identifying a hemodynamic target to guide treatment. Methods We measured blood pressure supine and upright (tilt or active standing) and identified the presence or absence of symptomatic OH by using a validated patient-reported outcome questionnaire in 210 patients with PD. We evaluated the usefulness of the 20/10 and 30/15 mmHg diagnostic criteria (systolic/diastolic) to identify symptomatic OH. Results Fifty percent of the PD patient cohort met criteria for the 20/10 fall and 30% for the 30/15 blood pressure fall. Among the patients who met either OH criteria, the percentage of those with symptoms was small (33% of those with 20/10 and 44% of those with 30/15 mmHg; 16% and 13%, respectively overall). Symptomatic OH was associated with an upright mean blood pressure below 75 mmHg. A mean standing blood pressure <75 mmHg had a sensitivity of 97% and a specificity of 98% for detecting symptomatic OH. Conclusions Although the prevalence of OH in PD is high, not all patients have symptoms of organ hypoperfusion. A mean standing blood pressure below 75 mmHg appears to be a useful benchmark when deciding whether the benefits of initiating pharmacological treatment of OH outweigh the risks of exacerbating supine hypertension.

In this article we investigate the changes observed in the scales that quantify the quality of life (PDQ-39) in patients that have already completed 1 and 2 years of bilateral subthalamic stimulation (DBS-STN). Fourteen patients were evaluated 1 year after DBS-STN; the evaluation was repeated on 11 of them, 2 years after surgery. All of them suffered from Parkinson's disease with a 14.3 (+/-5.7) years history of motor complications. Patients were selected according to CAPSIT criteria. All of them were implanted bilateral electrodes in the subthalamic nucleus. The parameters applied were UPDRS II, UPDRS III, PDQ-39, and the scale of quality of life for caregivers (SQLC). Scorings in motor scales (UPDRS III) improved 45% in relation to the first year, and 48% in relation to the second year (P < 0.001). Patient's quality of life (PDQ-39 summary index) improvement was 62% 2 years after surgery (P < 0.001), and caregivers' quality of life improvement was 68% (P = 0.002) by the same time. DBS-STN is a therapy that efficiently improves the quality of life of selected patients with Parkinson's disease. This improvement is still present 2 years after surgery and has a positive impact on caregivers quality of life.

Background: Safinamide modulates both dopaminergic and glutamatergic systems with positive effects on motor and non-motor symptoms of Parkinson’s disease (PD). The drug utilization study SYNAPSES was designed to investigate the use of safinamide in routine clinical practice, as recommended by the European Medicines Agency. Objective: To describe the occurrence of adverse events in PD patients treated with safinamide in real-life conditions. Methods: The SYNAPSES trial is an observational, European, multicenter, retrospective-prospective cohort study. Patients were followed up to 12 months with analyses performed in the overall population and in patients aged >75 years, with relevant comorbidities and with psychiatric conditions. Results: Of the 1610 patients included, 82.4% were evaluable after 12 months with 25.1% of patients >75 years, 70.8% with relevant comorbidities and 42.4% with psychiatric conditions. During observation 45.8% patients experienced adverse events, 27.7% patients had adverse drug reactions and 9.2% patients had serious adverse events. The adverse events were those already described in the patients’ information leaflet. The majority were mild or moderate and completely resolved and no differences were detected between the subgroup of patients. Clinically significant improvements were seen in the UPDRS motor score and in the UPDRS total score in ≥40% of patients, according to the criteria developed by Shulman et al. Conclusion: The SYNAPSES study confirms the good safety profile of safinamide even in special groups of patients. Motor complications and motor scores improved with clinically significant results in the UPDRS scale maintained in the long-term.

Background In the last few years, several studies have focused on describing and understanding how virtual coaches (ie, coaching program or smart device aiming to provide coaching support through a variety of application contexts) could be key drivers for health promotion in home care settings. As there has been enormous technological progress in the field of artificial intelligence and data processing in the past decade, the use of virtual coaches gains an augmented attention in the considerations of medical innovations. Objective This scoping review aimed at providing an overview of the applications of a virtual coach in the clinical field. In particular, the review focused on the papers that provide tangible information for coaching activities with an active implication for engaging and guiding patients who have an ongoing plan of care. Methods We aimed to investigate the use of the term virtual coach in the clinical field performing a methodical review of the relevant literature indexed on PubMed, Scopus, and Embase databases to find virtual coach papers focused on specific activities dealing with clinical or medical contexts, excluding those aimed at surgical settings or electronic learning purposes. Results After a careful revision of the inclusion and exclusion criteria, 46 records were selected for the full-text review. Most of the identified articles directly or indirectly addressed the topic of physical activity. Some papers were focused on the use of virtual coaching (VC) to manage overweight or nutritional issues. Other papers dealt with technological interfaces to facilitate interactions with patients suffering from different chronic clinical conditions such as heart failure, chronic obstructive pulmonary disease, depression, and chronic pain. Conclusions Although physical activity is a healthy practice that is most encouraged by a virtual coach system, in the current scenario, rehabilitation is the great absentee. This paper gives an overview of the tangible applications of this tool in the medical field and may inspire new ideas for future research on VC.

Objectives: This paper reports for the first time three cases of infection by HTLV-I via organ transplantation; all the organs coming from the same asymptomatic infected donor. The need is considered for the implementation of compulsory screenings for HTLV antibodies on organ donors and on blood banks. Methods: The determination of antibodies for HTLV-I/II on samples of serum and cerebral spinal fluid from the patients and the donor was performed by enzyme immunoassay and western blot. Analysis of proviral DNA was performed by polymerase chain reaction. To detect changes in the sequence of aminoacids, the tax gene was sequentiated, amplified, and compared with ATK prototype stocks. Spinal cord magnetic resonance imaging, cerebral spinal fluid, and somatosensory evoked potential studies were carried out in all patients. Results: All three transplanted patients developed a myelopathy within a very short period of time. In all three patients and donor the virus belonged to the Cosmopolitan A subtype. The homology of HTLV-I sequences recovered from the patients and donor was 100% in all four cases. Proviral load was high in all three patients. The factors that certainly contributed to the infection in the first place, and the development of the disease later, were on the one hand the high proviral load and their immunosupressed condition, and on the other the virus genotype, which proved to be an aggresive variant. However, the analysis of the histocompatibility antigen showed that two of the patients carried an haplotype that has been associated with a lower risk of developing this disease. Conclusions: It is argued that, although in Spain and other European countries there is not compulsory screening for HTLV antibodies because of the studies that show a low seroprevalence, in view of the cases here reported, and to avoid the serious consequences that such infection has on transplanted patients, compulsory screenings, both on organ donors and on blood banks, should be implemented.
