Black cohosh efficacy and safety for menopausal symptoms. The Spanish Menopause Society statement.

Objective: The increasing interest in Western countries regarding phytotherapy use to treat menopause-related symptoms has led the Spanish Menopause Society (AEEM) to update its position statement performed in 2009 on the role of black cohosh () for the treatment of menopausal symptoms.

Material And Methods: A panel of experts from both clinical and research backgrounds were assembled to investigate the best available evidence. Selected studies were obtained by an electronic search, including the Internet search engines MEDLINE-Pubmed (1997-December 2021) and the Cochrane Controlled Trials Register.

Prevalence of sarcopenia and associated factors in institutionalised older adult patients.

Background & Aims: Sarcopenia is a syndrome characterised by a progressive and generalised loss of skeletal muscle mass and strength with a risk of adverse outcomes such as physical disability, poor quality of life and death. The main aim of the present study was to establish the prevalence of sarcopenia using EWGSOP-defined criteria in institutionalised older adult patients in long-term care institutions. A secondary purpose was to identify the risk factors that develop Sarcopenia in this population.

Recommendations of the Spanish Menopause Society on the consumption of omega-3 polyunsaturated fatty acids by postmenopausal women.

The consumption of long-chain omega-3 polyunsaturated fatty acids (LCO3-PUFAs) has shown a great variety of beneficial effects, including cardiovascular, metabolic and inflammatory effects, which make them interesting for the postmenopausal woman. Because LCO3-PUFAs could be effective and safe during this period, a panel of experts from the Spanish Menopause Society met to establish a set of recommendations for their use in postmenopausal women based on the best available evidence. The decrease in triglycerides is the most consistent effect observed with LCO3-PUFAs (at doses greater than 3g/day).

Acute renal hemodynamic effects of dimanganese decacarbonyl and cobalt protoporphyrin.

Background: Heme oxygenase (HO) products have a protective role in acute renal failure (ARF) that may be hemodynamically mediated because the HO-derived carbon monoxide (CO) is an important control system of arteriolar tone. The vascular effects of HO may be caused directly through changes in CO synthesis, and indirectly by alterations in nitric oxide (NO) release. The present study evaluated in vivo the renal effects of a heme oxygenase inhibitor, Co(III)Protoporphyrin (CoPP) alone or in combination with the CO donor dimanganese decacarbonyl (Mn2(CO)10).

Antioxidant activity of maslinic acid, a triterpene derivative obtained from Olea europaea.

We investigated the effect of maslinic acid (a triterpene derivative obtained from olive pomace), on the susceptibility of plasma or hepatocyte membranes to lipid peroxidation (LPO), induced respectively by the hydroxyl radical (OH*) generated by Fe2+/H2O2 ex vivo and by the system Fe3+/ascorbate in vitro; moreover, three groups of animals used in the plasma study were pretreated with CCl4 (to generate CCl3-*). Endogenous plasma lipoperoxide levels and susceptibility to LPO were decreased in rats treated with maslinic acid, after exposure to OH* by Fe2+/H2O2 (Fenton reaction). Co-incubation with maslinic acid prevented hepatocyte membrane LPO as shown by the reduction of TBARS.

Free radical scavenger and antihepatotoxic activity of Rosmarinus tomentosus.

The free radical scavenger and antihepatotoxic activity from Rosmarinus tomentosus ethanolic extract and its fractions were studied, and also its membrane stabilizing activity in rat erythrocytes. Pretreatment with an ethanolic extract of R. tomentosus caused an important decrease in the CCl4-induced toxicity in rats liver, made evident by its effect on the levels of GPT and bilirubin in the serum and the malondialdehyde (MDA) concentration in the liver.
