MICROBIAL COLONIZATION

This study tested whether pulsed electromagnetic fields (PEMF) can reduce harmful bacteria and improve healing around dental implants. 35 healthy adults with at least two missing teeth took part. Researchers measured changes in bacteria types and gum tissue volume to see if PEMF …

This study tested whether taking a daily probiotic called Bifidobacterium longum for one month could improve skin barrier damage in people with obesity. 140 participants took either the active probiotic or an inactive placebo. The researchers measured skin water loss and checked …

This study tested whether an oral probiotic supplement could help restore healthy bacteria in the vagina. It included 32 women aged 35-43 with vaginal imbalance and fertility concerns. Researchers measured how well the probiotic colonized the body and its effects on immune and an…

This study tested if a cream with live good bacteria (Lactobacillus crispatus) could improve skin barrier damage in people with obesity. 98 adults aged 18-40 with a BMI of 25 or higher applied the cream or a placebo to their forearms daily for 4 weeks. The main goal was to see if…

This study looks at how different amounts of endurance exercise—from none to high levels—affect the bacteria living in the mouth of young adults aged 18 to 30. Researchers will collect saliva and gum samples to compare the oral microbiome and signs of inflammation. The goal is to…

This study checked whether using very low gas flow during anesthesia (minimal flow) leads to more germs in the breathing equipment. 140 adults having elective surgery were randomly assigned to minimal or normal flow. Researchers took swabs from the equipment and patients' noses t…

This completed study tested three different intensities of gentle neck movements designed to stimulate the vagus nerve in 128 healthy adults. Researchers measured changes in heart rate, balance, pain sensitivity, and digestion (via stool samples). The goal was to find the best 'd…

This study looked at how bacteria in the gut can change the way the body processes certain drugs. 17 healthy adults took specific medicines, and researchers measured drug levels in their blood. The goal was to better understand why people respond differently to the same drug, whi…

This study looked at whether giving antibiotics early to extremely low birthweight babies (born before 31 weeks) might cause more harm than good. Researchers compared babies who got standard antibiotics to those who got a placebo. The goal was to see if early antibiotics increase…

This study tested whether tagatose, a low-calorie sweetener, can act as a prebiotic—meaning it selectively feeds beneficial gut bacteria and improves blood sugar control. Fifty-nine healthy adults with slightly high blood sugar or insulin resistance took either tagatose or a plac…

This study looked at the gut bacteria of 200 heart attack patients, comparing those with high blood sugar to those with normal levels. Researchers collected stool samples before treatment and again at 6 and 12 months to see if changes in gut bacteria relate to survival. The goal …

This pilot study looked at whether giving donor human milk instead of formula to full-term babies whose mothers received antibiotics during labor could improve their gut bacteria and health. The study included 105 infants born vaginally at full term. Researchers compared the babi…

This study looked at how full-fat and fat-free milk and yogurt affect the gut microbiome and heart disease risk factors. 37 adults over 50 drank specially prepared dairy drinks for a period. Researchers measured changes in gut bacteria, metabolic byproducts, and blood markers to …

This study followed 461 children whose mothers took a special nutritional drink before and during pregnancy. Researchers want to understand how parents' diet, lifestyle, and metabolism influence child growth, thinking skills, and overall well-being. The goal is to identify factor…

This completed study at the University of Michigan compared how much bacteria builds up on 3D printed clear aligners versus conventional thermoformed aligners. Thirty participants wore each type of aligner for one week, and researchers swabbed both the aligners and tooth surfaces…

This study followed 603 pregnant women in South Africa to see if infections or bacteria in the vagina are linked to how early they give birth. Researchers tested for sexually transmitted infections, yeast, and other germs at the start of pregnancy and again at 30-34 weeks. The go…

This study looked at whether the types of bacteria in the gut are linked to whether pancreatic cancer has spread to nearby lymph nodes. Researchers compared stool samples from 55 patients with and without lymph node spread. They hope to find bacterial and chemical clues that coul…
