Complementary and Alternative Therapies for Genitourinary Syndrome of Menopause : An Evidence Map

BACKGROUND

Women seeking nonhormonal interventions for vulvovaginal, urinary, and sexual symptoms associated with genitourinary syndrome of menopause (GSM) may seek out complementary and alternative medicine or therapies (CAMs).

PURPOSE

To summarize published evidence of CAMs for GSM.

DATA SOURCES

Ovid MEDLINE, EMBASE, and CINAHL from inception through 11 December 2023.

STUDY SELECTION

Randomized controlled trials (RCTs) 8 weeks or more in duration that evaluated the effectiveness or harms of CAMs for postmenopausal women with GSM and reported 1 or more outcomes of interest, with sample sizes of 20 or more participants randomly assigned per group.

DATA EXTRACTION

Data were abstracted by 1 reviewer and verified by a second.

DATA SYNTHESIS

An evidence map approach was used to organize and describe trials. Studies were organized by type of intervention, with narrative summaries for population, study characteristics, interventions, and outcomes. Fifty-seven trials were identified that investigated 39 unique interventions. Studies were typically small (n < 200), and most were done in Iran (k = 24) or other parts of Asia (k = 9). Few trials evaluated similar combinations of populations, interventions, comparators, or outcomes. Most studies (k = 44) examined natural products (that is, herbal or botanical supplements and vitamins), whereas fewer reported on mind and body practices (k = 6) or educational programs (k = 7). Most studies reported 1 or 2 GSM symptoms, mainly sexual (k = 44) or vulvovaginal (k = 30). Tools used to measure outcomes varied widely. Most trials reported on adverse events (k = 33).

LIMITATIONS

Only English-language studies were used. Effect estimates, risk of bias, and certainty of evidence were not assessed.

CONCLUSION

There is a large and heterogeneous literature of CAM interventions for GSM. Trials were small, and few were done in North America. Standardized population, intervention, comparator, and outcomes reporting in future RCTs are needed.

Exploring fennel (Foeniculum vulgare): Composition, functional properties, potential health benefits, and safety

Fennel (Foeniculum vulgare Mill), a member of the Apiaceae family (Umbelliferaceae), is a hardy and perennial herb, with grooved stems, intermittent leaves, petiole with sheath, usually bisexual flower and yellow umbrella. Although fennel is a typical aromatic plant generally considered native to the Mediterranean shores, it has become widespread in many regions of the world and has long been used as a medicinal and culinary herb. The aim of this review is to collect recent information from the literature on the chemical composition, functional properties and toxicology of fennel. Collected data show the efficacy of this plant in various in vitro and in vivo pharmacological studies including antibacterial, antifungal, antiviral, antioxidant, anti-inflammatory, antimutagenic, antinociceptive, hepatoprotective, bronchodilatory, and memory enhancing activities. It has also been shown to be effective on infantile colic, dysmenorrhea, polycystic ovarian syndrome and milk production. This review also aims to identify gaps in the literature that require to be filled by future research.

Mechanistic Aspects of Apiaceae Family Spices in Ameliorating Alzheimer's Disease

Alzheimer's disease (AD) is one of the most prevalent neurodegenerative diseases worldwide. In an effort to search for new strategies for treating AD, natural products have become candidates of choice. Plants are a rich source of bioactive and effective compounds used in treating numerous diseases. Various plant extracts are known to display neuroprotective activities by targeting different pathophysiological pathways in association with the diseases, such as inhibiting enzymes responsible for degrading neurotransmitters, reducing oxidative stress, neuroprotection, inhibiting amyloid plaque formation, and replenishing mitochondrial function. This review presented a comprehensive evaluation of the available scientific literature (in vivo, in vitro, and in silico) on the neuroprotective mechanisms displayed by the extracts/bioactive compounds from spices belonging to the Apiaceae family in ameliorating AD.
