The Effect of a Physical Training with the Use of an Exoskeleton on Depression Levels in Institutionalized Elderly Patients: A Pilot Study.

CONTEXT: The Human Body Posturizer (HBP) is an exoskeleton used in the neurorehabilitation. The HBP may improve motor control by stimulating the pre-frontal cortex, a brain region involved also in the inhibitory modulation of the amygdala whose hyperactivity is involved in the mechanisms of depression. OBJECTIVE: The aim of the study was to investigate in institutionalized elderly patients the effects on depression of a physical training with the use of the HBP compared to a traditional training. DESIGN: Randomized controlled trial. PARTICIPANTS: 20 institutionalized patients (mean age = 88, ds = ± 5, 3 males) with moderate depression levels. INTERVENTION: The participants were randomly assigned to: a) HBP Group, which carried out physical training using the HBP; b) Excercise Group, which carried out a training without the use of the orthosis. The training was conducted for 6 months (3 sessions each week), with the same kind of exercises with or without the HBP according to the assignment group. MEASUREMENTS: Participants were evaluated at baseline using the Tinetti balance and Gait scale, the Mini Mental State Examination and the Geriatric Handicap Scale. The Geriatric Depression Scale was administered to the participants before and after the period of training. RESULTS: The two groups were homogeneous for age, baseline motor ability (risk falls), handicap score, cognitive functioning and depression levels. After 6 months of exercise training a significant reduction in depression levels was reported only in the HBP Group (p <.01). CONCLUSIONS: A positive effect of the HBP in the modulation of mood in institutionalized elderly subjects was found. It is possible to hypothesis that a traditional training without the HBP may require more time to achieve significant results. Clinical implications will be discussed.

Fall prevention in the young old using an exoskeleton human body posturizer: a randomized controlled trial.

BACKGROUND: Fall risk in elderly has been related with physical decline, low quality of life and reduced survival. AIM: To evaluate the impact of exoskeleton human body posturizer (HBP) on the fall risk in the elderly. METHODS: 150 subjects (mean age 64.85; 79 M/71 F) with mild fall risk were randomized into two groups: 75 for group treated with human body posturizer (HBP group) and 75 for physical training without HBP group (exercise group). The effects of interventions were assessed by differences in tests related to balance and falls. Medically eligible patients were screened with Tinetti balance and Gait evaluation scale, short physical performance battery and numeric pain rating scale to determine fall risk in elderly people. RESULTS: In the HBP group there was a significant improvement in short physical performance battery, Tinetti scale and Pain Numeric rating scale with a significant reduction in fall risk (p < 0.05). In the exercise group we observed only minimal variations in the test scores. DISCUSSION: The results at the sixth and twelfth months show a twofold positive effect in the HBP group reducing fall risk and improving quality of life by reducing pain. CONCLUSION: The use of exoskeleton human body posturizer seems to be a new significant device for prevention of fall in elderly patients. Further research should be carried out to obtain more evidence on effects of robotic technology for fall prevention in the elderly.

Exercise training and music therapy in elderly with depressive syndrome: a pilot study.

OBJECTIVE: Recent studies have thrown doubt on the true effectiveness of anti-depressants in light and moderate depression. The aim of this study is to evaluate the impact of physical training and music therapy on a sample group of subjects affected by light to moderate depression versus subjects treated with pharmacological therapy only. DESIGN AND SETTING: Randomized controlled study. Patients were randomized into two groups. Subjects in the pharmacotherapy group received a therapy with antidepressant drugs; the exercise/music therapy group was assigned to receive physical exercise training combined with listening to music. The effects of interventions were assessed by differences in changes in mood state between the two groups. MAIN OUTCOME MEASURES: Medically eligible patients were screened with the Hamilton Anxiety Scale and with the Geriatric Depression Scale. We used plasmatic cytokine dosage as a stress marker. RESULTS: We recruited 24 subjects (mean age: 75.5 ± 7.4, 11 M/13 F). In the pharmacotherapy group there was a significant improvement in anxiety only (p<0.05) at 6-months. In the exercise/music therapy was a reduction in anxiety and in depression at 3-months and at 6-months (p<0.05). We noted an average reduction of the level of TNF-a from 57.67 (± 39.37) pg/ml to 35.80 (± 26.18) pg/ml. CONCLUSIONS: Our training may potentially play a role in the treatment of subjects with mild to moderate depression. Further research should be carried out to obtain more evidence on effects of physical training and music therapy in depressed subjects.

Hypovitaminosis D: which oral supplement therapy?

OBJECTIVES: the possible therapeutic role of vitamin D in different kind of diseases explains the growing interest in this vitamin due to its pleiotropic effects. This short report shows preliminary results of prevalence of hypovitaminosis D in a group of patients and proposes a oral supplement therapy effective in correcting hypovitaminosis in a short time, without side effects. METHODS: 243 patients (aged 26-93; 67 males) were enrolled at this study. We evaluated plasma levels of 25-hydroxyvitamin D [25(OH)D] with the following cut-off values: <10 ng/ml or <0-25 nmol/L (deficient), 10-30 ng/ml or 25-75 nmol/L 30-50 (insufficient) and > 30 ng/ml or > 50 nmol/L (normal). The first 73 patients with hypovitaminosis D received at baseline 25,000 IU (Cholecalciferol) per os twice a month (Tp.A). The next patients (Tp.B) at baseline received a loading dose of 50,000 IU once a week for 8 weeks, followed by a maintenance dose of 25,000 IU twice a month. RESULTS: hypovitaminosis D is a widespread condition (i.e., 82.3%) not only in elderly (75.6% of 75 patients aged <65 yrs and 86.5% of 168 subjects aged >65 yrs). Preliminary results at 6 months show that Tp.B is more effective in correcting hypovitaminosis D (baseline 14.4 ± 5.3 ng/ml; 24 wk 43.3 ± 14.7 ng/ml; p<0.0001). CONCLUSION: hypovitaminosis D is an important public health problem. We believe it is important to quickly achieve normal Vit. D plasma values in order to produce pleiotropic effects.

Vitamin D: drug of the future. A new therapeutic approach.

Besides increasing calcium absorption in the bowel and promoting the normal formation and mineralization of bone, vitamin D exerts relevant pleiotropic effects in different tissues. Serum levels of vitamin D show correlation with the risk of infections, cardiovascular diseases, cancer and autoimmune disorders. The possible therapeutic role of vitamin D in different kind of diseases: inflammatory, immunologic, infectious and neoplastic ones, explains the growing interest in this vitamin due to its pleiotropic effects, and makes it a candidate to become a potential drug in the next future.

New frontiers of cognitive rehabilitation in geriatric age: the Mozart Effect (ME).

The ME was described for the first time in 1993. Subsequently other studies with similar designs were performed. The present study, therefore, proposes: (i) to verify the existence of the benefits of exposure to music in elderly subjects with mild cognitive impairment (MCI), (ii) to explore whether it is possible to find any lasting improvement after training, conducted for a long period of time, with such musical pieces, in the measurable cognitive performances. The study we conducted showed that the ME is present in geriatric patients with MCI; the influence on spatial-temporal abilities remains constant in time if the stimulation is maintained. The continuation of our study will consist of increasing the number of individuals examined and in having them listen to music during the study of ECG rhythms and during the acquisition of cerebral functional magnetic resonance imaging (fMRI), and, at the same time, testing them by neuropsychometric methods.

Third degree of atrioventricular block: a rare geriatric complication that may cause sudden death. Remarks on two clinical cases.

Two clinical cases are reported that have in common the electrocardiographic detection of a third degree atrioventricular block (AVB), which occurred in the first case in a man of 78 years, hospitalized in our unit after an accidental fall with an ensuing head trauma, and in the second case, in a woman of 67 years, after cataract surgery on her left eye. The complete or third degree AVB is a bradyarrhythmia characterized by the absence of paroxystic or permanent atrioventricular conduction. Several studies conducted on subjects between the ages of 60 and 85 pointed out that the incidence of AVB-type bradyarrhythmias of a degree greater than the first is extremely rare, i.e., it is close to zero. It is, however, necessary to make an early diagnosis of the AVB, as in many cases it may complicate the patient's clinical progress and may often lead to sudden death. Clinical and experimental observations have shown that electrocardiographic alterations and arrhythmias are frequent complications of cerebral accidents such as head traumas, or of ophthalmic surgery. It is therefore necessary, especially in elderly patients in whom bradyarrhythmias are characterized by the presence of widespread histological alterations of the conduction system, to perform a 24-h monitoring of all adverse events that may lead to an AVB.

Exaggerated morning blood pressure surge and cardiovascular events. A 5-year longitudinal study in normotensive and well-controlled hypertensive elderly.

Cardiovascular events (CE) occur most frequently in the morning hours in hypertensive subjects. We studied the association between the morning blood pressure (BP) surge and CE in prognosis of 10 normotensive and 32 well-controlled hypertensive elderly, in whom ambulatory BP monitoring was performed and who were followed prospectively for 5 years. The morning surge (MS) of BP was calculated as mean systolic BP during 2h after awakening--mean systolic BP during 1h that included the lowest sleep BP. During an average of 60 months, five CE occurred. When the patients were divided into two groups according to MS, those in the top terzile (MS group; MS> or =34 mmHg, n=14) had a higher prevalence of CE (5 versus 0, p=0.001) during the follow-up period, than the others (non-MS group; MS<34 mmHg, n=28). The logistic regression analysis showed the MS sleep-trough surge as predictive variable of CE (odds ratio, OR=0.794, p=0.022). In conclusion, in older normotensives and well-controlled hypertensives, a higher BP MS is associated with vascular risk independently of clinical and ambulatory BP. Reduction of the MS could thus be a therapeutic target for preventing vascular events also in non-hypertensive patients.
