A double-blind, randomized, placebo-controlled study assessing the impact of probiotic supplementation on the symptoms of irritable bowel syndrome in females

BACKGROUND

A previous exploratory study demonstrated the ability of the Lab4 probiotic to alleviate the symptoms of IBS, and post hoc data analysis indicated greatest improvements in the female subgroup. The aim of this study is to confirm the impact of this multistrain probiotic on IBS symptom severity in females.

METHODS

An 8-week, single-center, randomized, double-blinded, placebo-controlled, superiority study in 70 females with Rome IV-diagnosed irritable bowel syndrome (IBS) receiving the Lab4 probiotic (25 billion colony-forming units) daily or a matched placebo. Changes from baseline in the IBS-symptom severity score (IBS-SSS), daily bowel habits, anxiety, depression, IBS-related control, and avoidance behavior, executive function, and the fecal microbiota composition were assessed. The study was prospectively registered: ISRCTN 14866272 (registration date 20/07/22).

KEY RESULTS

At the end of the study, there were significant between-group reductions in IBS-SSS (-85.0, p < 0.0001), anxiety and depression scores (-1.9, p = 0.0002 and -2.4, p < 0.0001, respectively), and the IBS-related control and avoidance behavior score (-7.5, p = 0.0002), all favoring the probiotic group. A higher proportion of the participants in the probiotic group had normal stool form (p = 0.0106) and/or fewer defecations with loose stool form (p = 0.0311). There was little impact on the overall diversity of the fecal microbiota but there were significant differences in Roseburia, Holdemanella, Blautia, Agathobacter, Ruminococcus, Prevotella, Bacteroides, and Anaerostipes between the probiotic and placebo groups at the end of the study.

CONCLUSIONS & INFERENCES

Daily supplementation with this probiotic may represent an option to be considered in the management of IBS.

Tumescent liposuction complicated by pulmonary edema

In tumescent liposuction, large volumes of dilute lidocaine and epinephrine are infused subcutaneously to prepare fat for extraction. Reported cardiopulmonary complications of tumescent liposuction have been few, and the anesthetic and hemodynamic advantages are several. We report an instance of pulmonary edema in a healthy 55-year-old male body-builder who received 7900 cc subcutaneous and 2200 cc intravenous fluid. With normal cardiopulmonary and renal function, the patient responded promptly to intravenous diuretics without sequelae. Out of over 900 patients who have had tumescent liposuction with up to 15 liters infused parenterally, this is the first case of pulmonary edema.

The role of marketing for GDPs (general dentist practitioners)

Dentists, while recognising the need to be more marketing orientated, still have some way to go to improve the perception of themselves and their services in the eyes of the public. Nigel Coates and John Willans suggest some ways to address the barriers to visiting dentists.
