An Evaluation of the Effects of Pineapple-Extract and Bromelain-Based Treatment after Mandibular Third Molar Surgery: A Randomized Three-Arm Clinical Study.

A three-arm, randomized, placebo-controlled clinical study was conducted to assess the impact of lyophilized pineapple extract with titrated bromelain (Brome-Inf®) and purified bromelain on pain, swelling, trismus, and quality of life (QoL) following the surgical extraction of the mandibular third molars. Furthermore, this study examined the need for Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) by comparing their effects with a placebo group. This study enrolled 42 individuals requiring the extraction of a single mandibular third molar under local anesthesia. The patients were randomly assigned to receive Brome-Inf®, purified bromelain, or a placebo orally, initiating treatment on the day of surgery and continuing for the next 7 days. The primary outcome measured was the requirement for NSAIDs in the three groups. Pain, swelling, and trismus were secondary outcome variables, evaluated postoperatively at 1, 3, and 7 days. This study also assessed the comparative efficacy of freeze-dried pineapple extract and single-component bromelain. Ultimately, the placebo group showed a statistically higher need for ibuprofen (from days 1 to 7) at the study's conclusion (p < 0.0001). In addition, reductions in pain and swelling were significantly higher in both the bromelain and pineapple groups (p < 0.0001 for almost all patients, at all intervals) than in the placebo group. The active groups also demonstrated a significant difference in QoL compared to the placebo group (p < 0.001). A non-significant reduction in trismus occurred in the treatment groups compared to the placebo group. Therefore, the administration of pineapple extract titrated in bromelain showed significant analgesic and anti-edema effects in addition to improving QoL in the postoperative period for patients who had undergone mandibular third molar surgery. Moreover, both bromelain and Brome-Inf® supplementation reduced the need for ibuprofen to comparable extents, proving that they are good alternatives to NSAIDs in making the postoperative course more comfortable for these patients. A further investigation with larger samples is necessary to assess the pain-relieving and anti-inflammatory impacts of the entire pineapple phytocomplex in surgical procedures aside from mandibular third molar surgery.

Short-Term Effect of Nutraceutical Fruit Juices on Lipid Metabolism in Patients with Acquired Hypercholesterolemia.

The crucial role of dyslipidaemia, especially hypercholesterolemia, in the development of atherosclerosis-related cardiovascular diseases has been extensively documented in genetic, pathologic, observational and intervention studies. The European guidelines for dyslipidaemia management include the possible use of lipid-lowering nutraceuticals to support a relatively large number of natural compounds. In this context, we have conducted a study to investigate whether dietary supplementation with a functional nutraceutical beverage, containing a standardized polyphenolic fraction from fruit, red yeast rice, phytosterols, and berberine complexed with ß-cyclodextrin, could positively affect serum lipid concentration in 14 subjects with hypercholesterolemia. After 12 weeks of treatment, dietary supplementation with this nutraceutical combination was associated with significant improvements in total cholesterol, low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol (non-HDL-C) and apolipoprotein B, compared to baseline. Compliance was excellent and no adverse effects were reported. In conclusion, this study demonstrates that 100 mL of a functional beverage containing lipid-lowering nutraceuticals safely leads to significant improvements in serum lipids in subjects with moderate hypercholesterolemia. Future research is needed to unravel the role that the polyphenols contained in fruit extracts play in the reduction of cholesterolemia and in cardiovascular disease prevention.

Effectiveness of the integration of quercetin, turmeric, and N-acetylcysteine in reducing inflammation and pain associated with endometriosis. In-vitro and in-vivo studies.

BACKGROUND: to evaluate the efficacy of oral administration of a novel composition composed of quercetin, curcumin, acetylcysteine in reducing pain in women affected by endometriosis, through the reduction of the inflammatory-hyperproliferative component of the ectopic endometrial tissue. METHODS: Thirty-three women with clinical diagnosis of endometriosis from at least 3 months have been enrolled. Patients have been treated daily with 200 mg of quercetin, 210 mg of dry extract of Curcuma longa (titrated at 95% in curcuminoids) and 150 mg of acetylcysteine (1 tablet of ALLIENDO®) for 2 months. The overall symptomatology with specific reference to dysmenorrhea, pelvic pain and dyspareunia, together with the frequency of nonsteroidal anti-inflammatory drugs (NSAID) drugs assumption have been evaluated at the beginning and at the end of the treatment. RESULTS: Overall, the results collected at the end of the treatment according to the parameters evaluated and above mentioned on the 33 patients enrolled, show a significative improvement in the reduction of pain symptoms associated to endometriosis (P<0.001 for dysmenorrhea, pelvic pain and dyspareunia). The use of NSAIDs together with an overall reduction of their dosage and time of assumption has been reduced as well. No significative side effects have been observed. CONCLUSIONS: The aforementioned results suggest that administration of the composition described can represent a valuable adjuvant treatment in the reduction of pain symptomatology associated to endometriosis, triggered by inflammatory cascade and hyperproliferation of ectopic tissue.

Lipomatrix: A Novel Ascorbyl Palmitate-Based Lipid Matrix to Enhancing Enteric Absorption of Serenoa Repens Oil.

The class of lipophilic compounds coming from vegetal source represents a perspective in the adjuvant treatment of several human diseases, despite their poor bioavailability in humans. These compounds are generally soluble in fats and poorly soluble in water. The major reason for the poor bioavailability of lipophilic natural compounds after oral uptake in humans is related to their reduced solubility in enteric water-based fluids, leading to an ineffective contact with absorbing epithelium. The main goal to ensure efficacy of such compounds is then creating technological conditions to deliver them into the first enteric tract as hydro-dispersible forms to maximize epithelial absorption. The present work describes and characterizes a new technological matrix (Lipomatrix, Labomar Research, Istrana, TV, Italy) based on a molten fats core in which Ascorbyl Palmitate is embedded, able to deliver lipophilic compounds in a well-dispersed and emulsified form once exposed to duodenal fluids. Authors describe and quantify Lipomatrix delivery of Serenoa repens oil through an innovative in vitro model of human gastro-enteric digestion, reporting results of its improved bioaccessibility, enteric absorption and efficacy compared with not formulated Serenoa repens oil-containing commercial products using in vitro models of human intestine and prostatic tissue.
