Microbes in the Production of Fermented Foods01:27

Microbes in the Production of Fermented Foods

Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...

Drugs Affecting GI Tract Motility: Other Laxatives

Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
Osmotic or saline laxatives, like magnesium hydroxide or milk of...

Drugs for Treatment of Constipation-Predominant IBS

Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...

Summary
This summary is machine-generated.

This pilot study suggests that herbal lollipops with licorice root may reduce Streptococcus mutans (S. mutans) bacteria in nursing home residents. Further research with larger samples is recommended to confirm these findings on dental caries prevention.

Area of Science:

  • Geriatric Medicine
  • Microbiology
  • Dental Public Health

Background:

  • Dental caries is a significant oral health issue, particularly in vulnerable populations like nursing home residents.
  • Streptococcus mutans (S. mutans) is a primary bacterial agent responsible for the initiation of dental caries.
  • Non-invasive methods for managing S. mutans are crucial for improving oral health in elderly individuals.

Purpose of the Study:

  • To investigate the efficacy of an herbal lollipop containing licorice root in reducing S. mutans levels.
  • To assess the potential of licorice root as a natural agent for caries prevention in a geriatric population.

Main Methods:

  • A pilot study involving 8 nursing home residents (mean age 85).
  • Participants consumed two licorice root lollipops daily for 21 days.
  • Saliva samples were collected at baseline and multiple time points for S. mutans analysis.

Main Results:

  • A trend indicated that higher lollipop consumption correlated with lower S. mutans counts.
  • Linear mixed-models analysis showed a trend toward reduction (β = -8.703, p = 0.067).
  • The study did not achieve statistical significance, suggesting a need for larger sample sizes.

Conclusions:

  • Herbal lollipops with licorice root show a promising trend in reducing S. mutans in nursing home residents.
  • Larger-scale studies are warranted to confirm the significant impact of licorice root on dental caries prevention.
  • This approach may offer a novel, natural intervention for oral health management in the elderly.
