The effect of exercise training on blood pressure in menopause and postmenopausal women: A systematic review of randomized controlled trials

2021

The prevalence of hypertension is higher in postmenopausal than in premenopausal women. Regular exercise training has been shown to be effective in addressing hypertension. The aim of this systematic review was to synthesize the effect of exercise training on systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) in menopausal and postmenopausal women. This review was reported according to the PRISMA statement and registered in PROSPERO. The literature search was done in MEDLINE, Embase, Cochrane CENTRAL and ClinicalTrials. Randomized controlled trials involving menopausal and postmenopausal women undergoing exercise training were included. Two blinde…

Mediterranean diet and health: A systematic review of epidemiological studies and intervention trials

2019

Diet is a crucial variable for a healthy life. A rapidly growing number of studies in recent years support the hypothesis that the Mediterranean diet (MedDiet) has a beneficial effect on certain body systems, but the highly varied objectives and quality of these publications warrants an updated assessment. In the present review we performed a comprehensive evaluation of current evidence on the impact of the MedDiet on human health, assessing its effect on the incidence or progression of the main non-communicable diseases and their intermediate outcomes and risk factors. We scrutinised the clinical evidence from observational studies and randomised controlled trials. Cardiovascular disease w…

An O2-sensitive glomus cell-stem cell synapse induces carotid body growth in chronic hypoxia.

2013

Summary Neural stem cells (NSCs) exist in germinal centers of the adult brain and in the carotid body (CB), an oxygen-sensing organ that grows under chronic hypoxemia. How stem cell lineage differentiation into mature glomus cells is coupled with changes in physiological demand is poorly understood. Here, we show that hypoxia does not affect CB NSC proliferation directly. Rather, mature glomus cells expressing endothelin-1, the O 2 -sensing elements in the CB that secrete neurotransmitters in response to hypoxia, establish abundant synaptic-like contacts with stem cells, which express endothelin receptors, and instruct their growth. Inhibition of glomus cell transmitter release or their sel…

Mitochondrial dysfunction in cholestatic liver diseases

2011

et al.

2018

Beyond the classical paradigm that presents the Anticipatory Postural Adjustments (APAs) as a manner to create forces that counteract disturbances arising from the moving segment during a pointing task, there is a controversial discussion about the role APAs to facilitate the movement and perform a task accurately. In addition, arm kinematics features are classically used to infer the content of motor planning for the execution and the control of arm movements. The present study aimed to disentangle the conflicting role of APAs during an arm-pointing task in which the subjects reach a central diode that suddenly turns on, while their postural stability was manipulated. Three postures were a…

Effects of a Rehabilitation Program on Perceived Environmental Barriers in Older Patients Recovering from Hip Fracture: A Randomized Controlled Trial

2013

Objectives. To study effects of a one-year multicomponent intervention on perceived environmental barriers in hip fracture patients.Design. Randomized controlled trial of a 12-month home-based rehabilitation aiming to improve mobility and function (ISRCTN53680197); secondary analyses.Subjects. Community-dwelling hip fracture patients on average 70 days after trauma (n=81).Methods. Assessments at baseline, 3, 6, and 12 months later included perceived entrance-related barriers (e.g., indoor/outdoor stairs, lighting, floor surfaces, and storage for mobility devices) and perceived barriers in the outdoor environment (poor street condition, hilly terrain, long-distances, and lack of resting plac…

Several point mutations have been identified in human aquaporins, but their effects on the function of the respective aquaporins are mostly enigmatic. We analyzed the impact of the aquaporin 2 mutation V71M, which causes nephrogenic diabetes insipidus in humans, on aquaporin structure and activity, using the bacterial aquaglyceroporin GlpF as a model. Importantly, the sequence and structure around the V71M mutation is highly conserved between aquaporin 2 and GlpF. The V71M mutation neither impairs substrate flux nor oligomerization of the aquaglyceroporin. Therefore, the human aquaporin 2 mutant V71M is most likely active, but cellular trafficking is probably impaired.

Monitoring and use of antimycotic (micafungin) for systemic use provided by the pharmacy of Marsala Hospital, Italy

2016

Micafungin is an antimycotic drug and represents an important addition to the available therapies for the treatment of systemic fungal infections. Micafungin is used: in the treatment of invasive candidiasis, oesophageal and prophylaxis of <em>Candida</em> infections. It inhibits, in a non-competitive way, the synthesis of 1,3-β-D-glucan, a component of fungal cell wall and is rapidly distributed into the tissues. It has a high-rate respectful bond with plasma protein, which is independent from the concentration of the drug. It is metabolized through the liver, being not subject to intense metabolic transformations until the excretion. There is no evidence of systemic accumulati…

Correlates of hormone replacement therapy use in Italian women, 1992-1996

1999

we analyzed the determinants of hormonal replacement therapy (HRT) use in Italy for the period 1992-1996, using data from a framework of case-control studies of colon and rectal neoplasm.a total of 1574 women aged 45-74 years were considered. This group comprised women with acute, non neoplastic, non-hormone-related diseases admitted to a network of hospitals in six areas of Italy.a total of 146 women (8.5%) reported ever HRT use. The multivariate odds ratio (OR) of ever use was 1.6 (95% CI 1.0-2.6) for women with 12 years of education or more, compared with those with7 years. The frequency of use of HRT tended to decrease with increasing parity: the OR was 0.6 for women with four or more c…
