Physical activity and exercise for the prevention and management of mild cognitive impairment and dementia: a collaborative international guideline

BACKGROUND

Physical activity and exercise have been suggested as effective interventions for the prevention and management of mild cognitive impairment (MCI) and dementia, but there are no international guidelines.

OBJECTIVES

To create a set of evidence- and expert consensus-based prevention and management recommendations regarding physical activity (any bodily movement produced by skeletal muscles that results in energy expenditure) and exercise (a subset of physical activity that is planned, structured, repetitive), applicable to a range of individuals from healthy older adults to those with MCI/dementia.

METHODS

Guideline content was developed with input from several scientific and lay representatives' societies. A systematic search across multidisciplinary databases was carried out until October 2021. Recommendations for prevention and management were developed according to the GRADE and complemented by consensus statements from the expert panels.

RECOMMENDATIONS

Physical activity may be considered for the primary prevention of dementia. In people with MCI there is continued uncertainty about the role of physical activity in slowing the conversion to dementia. Mind-body interventions have the greatest supporting evidence. In people with moderate dementia, exercise may be used for maintaining disability and cognition. All these recommendations were based on a very low/low certainty of evidence.

CONCLUSIONS

Although the scientific evidence on the beneficial role of physical activity and exercise in preserving cognitive functions in subjects with normal cognition, MCI or dementia is inconclusive, this panel, composed of scientific societies and other stakeholders, recommends their implementation based on their beneficial effects on almost all facets of health.

Cardiac sympathetic innervation and mortality risk scores in patients with heart failure

INTRODUCTION

In the risk stratification and selection of patients with heart failure (HF) eligible for implantable cardioverter-defibrillator (ICD) therapy, ¹²³ I-meta-IodineBenzylGuanidine (¹²³ I-mIBG) scintigraphy has emerged as an effective non-invasive method to assess cardiac adrenergic innervation. Similarly, clinical risk scores have been proposed to identify patients with HF at risk of all-cause mortality, for whom the net clinical benefit of device implantation would presumably be lower. Nevertheless, the association between the two classes of tools, one suggestive of arrhythmic risk, the other of all-cause mortality, needs further investigation.

OBJECTIVE

To test the relationship between the risk scores for predicting mortality and cardiac sympathetic innervation, assessed through myocardial ¹²³ I-mIBG imaging, in a population of patients with HF.

METHODS

In HF patients undergoing ¹²³ I-mIBG scintigraphy, eight risk stratification models were assessed: AAACC, FADES, MADIT, MADIT-ICD non-arrhythmic mortality score, PACE, Parkash, SHOCKED and Sjoblom. Cardiac adrenergic impairment was assessed by late heart-to-mediastinum ratio (H/M) <1.6.

RESULTS

Among 269 patients suffering from HF, late H/M showed significant negative correlation with all the predicting models, although generally weak, ranging from -0.15 (p = .013) for PACE to -0.32 (p < .001) for FADES. The scores showed poor discrimination for cardiac innervation, with areas under the curve (AUC) ranging from 0.546 for Parkash to 0.621 for FADES.

CONCLUSION

A weak association emerged among mortality risk scores and cardiac innervation, suggesting to integrate in clinical practice tools indicative of both arrhythmic and general mortality risks, when evaluating patients affected by HF eligible for device implantation.

Comparison of different oval window sealing materials in stapes surgery: systematic review and meta-analysis

OBJECTIVE

To compare the efficacy and safety characteristics of different materials used for oval window sealing during stapedotomy.

METHODS

A systematic review was conducted according to the PRISMA guidelines. Published international English literature from January 1, 2000 to December 2021 was screened, checking for studies that compared different materials utilization in patients undergoing stapedotomy surgery for otosclerosis or congenital stapes fixation. Data related to the efficacy and safety of each material were extracted. The primary outcome measure was the air-bone gap (ABG) closure after surgical intervention.

RESULTS

Six studies were included in the metanalysis. Because of the heterogeneity of the treatments adopted, we assessed the use of the fat compared to all other treatments, and the use of the gelfoam compared to all other treatments. In the former analysis (fat vs others) we did not identify differences in ABG closure between the groups (p = 0.74), with a low heterogeneity of the results (I² = 28.36%; Hedge's g = 0.04, 95% CI - 0.19 0.27); similarly, we did not identify differences between the use of gelfoam and other treatments (p = 0.97), with a low heterogeneity of the results (I² = 28.91%; Hedge's g = 0.00, 95% CI - 0.20 0.21).

CONCLUSIONS

Numerous options are available for oval window sealing during stapedotomy, with acceptable safety and effectiveness profiles. Based on the current data, no definitive recommendation can be made regarding the choice of one material over another, and the convenience of sealing over no sealing at all.

The aging process in prison: pathologies and health conditions in old inmates. An epidemiological research in Italy

BACKGROUND AND AIMS

Elderly may suffer from different pathologies during their detention in jail because of their age. Conditions in jails were tough and adapting to that life could be problematic for the elder population. This article aimed to analyse the pathologies and health conditions in a sample of elder inmates from Italy.

METHODS

The sample was composed by 94 elderly inmates. The research is multicentric. We selected jails from the cities of Bari, Taranto, Foggia, Lecce, Brescia, Bergamo, Cremona and Mantua. The study was conducted by interviewing the prisoners over 60 years of age, in the period between September and December 2017.

RESULTS

64% of the sample was in a "Not Optimal" health status. Most of pathologies were Cardiac pathologies (23.4%), Diabetes (12.8 %) and Surgery (9.6%). Statistically significant differences were found for heart disease (p=0.02) and Neoplasia (p=0.025) in the prison of Bari compared to all the other prisons. Statistically significant differences were found for Hypertension in Foggia and Taranto prisons compared to all the other (p=0.023). Furthermore, 18.1% of inmates ended up having an addiction.

CONCLUSIONS

Our analysis showed that in our sample physical problems were more frequent than psychological one. In fact, in spite of in the literature there was a high prevalence of mental health problems among elderly inmates, we did not find this result. However, stress conditions may increase the risk of pathologies: for example, being in jail and adapt to new hard environment may increase the risk of getting sick. Heart disease pathologies and diabetes were very common in our sample as confirmed by the literature.

Biosimilar epoetin α is as effective as originator epoetin-α plus liposomal iron (Sideral®), vitamin B12 and folates in patients with refractory anemia: A retrospective real-life approach

Several biosimilar versions of recombinant human erythropoietin are currently approved for use in Europe, including a biosimilar epoetin-α. The aim of this the study was to verify that biosimilar epoetin-α is similar in terms of efficacy, safety and cost to originator epoetin-α for the treatment of refractory anemia in patients with myelodysplastic syndrome. A total of 92 patients with myelodysplasia and refractory anemia were investigated. The patients received either originator (group A) or biosimilar (group B) epoetin-α. In addition, they received liposomal iron (Sideral®), calcium levofolinate and vitamin B12. Moreover, the median monthly overall costs were calculated for each group. The results demonstrated that hemoglobin (Hb) levels increased by 1 g/dl after a median time of 5 weeks in group A and 4 weeks in group B. In group A, a Hb level of >12 g/dl was achieved after 12 weeks, while in group B after 10.5 weeks. The median cost of therapy was 1,536 euros/month in group A and 1,354 euros/month in group B. A total of 5 patients required transfusion support in group A and 7 in group B. In conclusion, biosimilar epoetin-α appears to be comparable to originator epoetin-α in terms of efficacy and safety for the treatment of refractory anemia.

FFAs and QT intervals in obese women with visceral adiposity: effects of sustained weight loss over 1 year

We evaluated 66 obese patients grouped by waist-to-hip ratio (WHR) into group A (WHR > 0.85, n = 30) and group B (WHR < or = 0.85, n = 36), before and after 1 yr of diet-induced weight loss compared with 25 nonobese women. Before diet, the longest values of QT intervals and the highest levels of FFA and catecholamines were in group A (P < 0.01). In obese women (both groups), the corrected QT (QTc); interval correlated with plasma FFA (P < 0.01) and catecholamine (P < 0.02) concentrations. After 1 yr of diet, at the same levels of body weight reduction, the decrement of the QTc interval (P < 0.02), FFA (P < 0.01) and catecholamine (P < 0.02) levels were significantly greater in-group A than group B. In multivariate analysis, the decline of the QTc interval after weight loss was associated with changes in plasma FFA independently of changes in WHR and plasma catecholamines. Our data suggest that the QTc interval is tightly correlated with plasma FFA levels; shortening of cardiac repolarization times in the course of long-lasting weight reduction may reduce the risk of ventricular electrical instability, especially in women with abdominal adiposity.
