Up to 50% of patients suffering from acute decompensated heart failure show normal or slightly reduced left ventricular ejection fraction (LVEF). This syndrome, which is known as heart failure with preserved ejection fraction (HFpEF) is associated with increasing age. Epidemiological studies could portrait an increasing importance and an even emerging prevalence in the past decades. Still, there is currently no evidenced based medical treatment option available. Our aims were to identify upcoming trends and emerging concepts and to point out important centers in the global research of HFpEF. ⋯ This first bibliometric study in the field of HFpEF shows a substantial increase of research within the last decade, mainly in the USA, Japan, and continental Europe. As an ongoing therapeutic trend in this field, we identified RAAS-blockade and 5-phosphodiesterase-inhibition.

Exploring the association of early life physical activity and risk of dementia: a systematic review.
Physical activity has been included in the list of twelve modifiable risk factors for dementia, despite conflicting results from observational and controlled studies. In particular it is not clear whether physical inactivity near the time of dementia diagnosis is a consequence or cause of dementia. We review all available studies reporting the possible association between having engaged in PA before 60 years of age and the risk of dementia. ⋯ This review suggests that there is insufficient evidence to conclude whether PA in early life may affect the incidence of dementia in later life. Studies in this field are very complicated and recognizing the impact of PA in early life given all the confounding factors is very difficult. Further studies are warranted. In these studies, it will be crucial to define the type, quantity and intensity of PA as well as to stratify analysis by sex, cultures and social classes.

The progressive ageing of the population is one of the main socio-demographic phenomena, taking place at a global level. Several recent population-based studies conducted worldwide suggest that the age-specific risk of dementia may be changing in some countries and areas. ⋯ The present systematic review focused on the recent observations of a possible decrease in the frequency of dementia and cognitive impairment in some Western countries (USA, UK, Sweden, the Netherlands, France, Iceland) between 1977 and 2014. The included studies have a high heterogeneity in terms of the clinical criteria used to diagnose dementia, and of the criteria used to define the clinical condition preceding dementia, such as isolated cognitive impairment. Moreover, the methodological quality with which they were conducted was also heterogeneous, with scores ranging from 1 to 7 using the MORE tool.

The neurologic complications of rheumatic diseases (RDs) are highly variable, and their manifestations are linked to the pathogenesis and clinical phenotype of the specific RDs. In rheumatoid arthritis, for example, the peripheral nervous system is most commonly involved and mononeuritis multiplex, nerve entrapment and vasculitic sensorimotor neuropathies are not uncommon. Often the therapy for these disorders is not easy and is characterized by the use of different drugs. Palmitoylethanolamide (PEA) has been tested in a wide variety of animal models and has been evaluated in several clinical studies for nerve compression syndromes, demonstrating that PEA acts as an effective and safe analgesic compound. Acetyl-L-Carnitine (ALC) has also been shown to be an effective and safe treatment in painful peripheral neuropathy. In the last years the synergistic effect between PEA and ALC has been demonstrated. The aim of our study was to evaluate the efficacy of supplementation of standard therapy (STh) with Kalanit® (Chiesi Italia Spa; Parma, Italy) in patients with peripheral neuropathy secondary to RDs. ⋯ The synergistic effect of PEA and ALC seems to have a further advantage in the treatment of this type of pathology, including the anti-inflammatory effect but also in terms of therapy optimization and therefore of better adherence to treatments. Our study shows that it is important to identify the type of pain to follow an accurate diagnostic algorithm, considering the clinical characteristics of the patient and carefully evaluate the indication, preferring a multimodal approach.
