Key clinical point: Risk for shoulder dystocia was higher among women with gestational diabetes who showed a slowly improving glycemic control trajectory, highlighting the need for interventions that help achieve glycemic targets early after the diagnosis of gestational diabetes.

Major finding: Compared with women showing rapid improvements to attain optimal glycemic control, the risk for shoulder dystocia was higher among women showing slow improvements to attain suboptimal glycemic control (adjusted relative risk [aRR] 1.41; 95% CI 1.12-1.78) and was lower among women with stably optimal glycemic control from diagnosis to delivery (aRR 0.75; 95% CI 0.61-0.92).

Study details: Findings are from a population-based longitudinal cohort study including 26,774 women with gestational diabetes who received prenatal care.

Key clinical point: Use of low-dose aspirin significantly reduced preterm birth rates but had no significant effect on the risk for preeclampsia in pregnant women with chronic hypertension.

Major finding: In women with chronic hypertension, the use of low-dose aspirin vs placebo during pregnancy was associated with a significant reduction in preterm birth rates (22.2% vs 31.1%; odds ratio, 0.63; 95% CI 0.45-0.89) but a nonsignificant reduction in the risk for superimposed or preterm preeclampsia.

Study details: Findings are from a systematic review and meta-analysis of nine studies (retrospective cohort studies and randomized controlled trials) including 2150 women with chronic hypertension who received low-dose aspirin or placebo during pregnancy.

Key clinical point: Gut microbial composition differed among patients with diarrhea-predominant irritable bowel syndrome (IBS-D) who were positive vs negative for breath test (IBS-BT+ vs IBS-BT−), with patients who were IBS-BT+ responding better to rifaximin therapy.

Major finding: Beta-diversity differed significantly among patients with IBS-BT+, those with IBS-BT−, and non-IBS healthy controls (P = .005). The IBS Symptom Severity Scores (SSS), Gastrointestinal Symptom Rating Scale scores, and Bristol Stool Form Scale scores decreased significantly after rifaximin treatment in the IBS-BT+ group (all P < .05); however, only IBS-SSS scores decreased significantly in the IBS-BT− group (P = .001).

Study details: The data come from a clinical trial including 176 participants, of which 49 were BT− healthy controls and 127 were patients with IBS-D who were evaluated before and after rifaximin therapy.

Key clinical point: Breath gas patterns are linked to distinct gut microtypes in diarrhea-predominant irritable bowel syndrome (IBS-D) and constipation-predominant IBS (IBS-C).

Major finding: Patients with IBS-D vs IBS-C had a higher area under the curve (AUC) for hydrogen (P = .02) and hydrogen sulfide (P = .002), whereas those with IBS-C vs IBS-D had a higher AUC for methane (P = .002). Higher breath methane in IBS-C correlated with higher breath microbial diversity, whereas higher breath hydrogen and hydrogen sulfide in IBS-D correlated with lower microbial diversity and higher relative abundance of hydrogen sulfide-producing bacteria, respectively.

Study details: The data come from two randomized controlled trials including patients with IBS-C (n = 124) and IBS-D (n = 47).

Key clinical point: Fecal microbiota transfer (FMT) did not appear to be an effective treatment for irritable bowel syndrome (IBS) symptoms whether administered orally or via colonoscopy, gastroscopy, or a nasojejunal tube, with initial improvements wearing off drastically over time.

Major finding: Despite a significant improvement in the quality-of-life score in the FMT vs control group (mean difference 9.32; P = .0005), the overall change in IBS symptom severity score (P = .67) and the number of respondents considering all routes of administration (P = .19) were not significantly different between treatment arms.

Study details: Findings are from a meta-analysis of eight randomized controlled trials including 472 patients with IBS who received either FMT or autologous transfer/placebo (control group).

Key clinical point: Disgust sensitivity may act as a potential trigger or predisposition factor for irritable bowel syndrome (IBS), particularly in women.

Major finding: Disgust sensitivity was positively correlated with IBS (correlation coefficient [r] 0.251; P = .014), with the correlation being significant in women (P = .021) but not in men (P = .505). No correlation was observed between IBS and disgust propensity (P = .911) or total disgust score (P = .115).

Key clinical point: Cimetropium, drotaverine, and acupuncture were more effective in improving abdominal pain than placebo in patients with irritable bowel syndrome (IBS), with acupuncture being more effective than pinaverium in relieving global IBS symptoms and causing fewer adverse events than other antispasmodics.

Major finding: Cimetropium (standardized mean difference [SMD] −3.00; 95% CI −4.47 to −1.53) was the most effective for relieving abdominal pain, with drotaverine, acupuncture, and pinaverium being superior to placebo. Acupuncture vs pinaverium more effectively relieved global IBS symptoms (SMD −1.11; 95% CI −1.94 to −0.28). The adverse event rate was lower with acupuncture vs most antispasmodics.

Key clinical point: Treatment with anaerobically cultivated human intestinal microbiota (ACHIM) suspension or donor fecal microbiota transplantation (donor-FMT) but not placebo changed gut microbiota profiles in patients with irritable bowel syndrome (IBS) to those measured in healthy control individuals along with significant changes in bacterial strain signal.

Major finding: Patients receiving donor-FMT vs placebo had more significant bacterial strain signals for Actinobacteria spp. and Bifidobacteria spp., whereas those receiving ACHIM or donor-FMT vs placebo had more significant signals for Alistipes onderdonkii (all P < .05). After receiving ACHIM suspension or donor-FMT, but not placebo, the bacterial signal in patients resembled more that in healthy controls. No post-transplant complications were reported.

Study details: The data come from a randomized controlled study including 43 patients with IBS-D who received ACHIM suspension (n = 17), donor-FMT (n = 11), or placebo (patient’s own feces; n = 15).

Key clinical point: Treatment with anaerobically cultivated human intestinal microbiota (ACHIM) suspension or donor fecal microbiota transplantation (donor-FMT) but not placebo changed gut microbiota profiles in patients with irritable bowel syndrome (IBS) to those measured in healthy control individuals along with significant changes in bacterial strain signal.

Major finding: Patients receiving donor-FMT vs placebo had more significant bacterial strain signals for Actinobacteria spp. and Bifidobacteria spp., whereas those receiving ACHIM or donor-FMT vs placebo had more significant signals for Alistipes onderdonkii (all P < .05). After receiving ACHIM suspension or donor-FMT, but not placebo, the bacterial signal in patients resembled more that in healthy controls. No post-transplant complications were reported.

Study details: The data come from a randomized controlled study including 43 patients with IBS-D who received ACHIM suspension (n = 17), donor-FMT (n = 11), or placebo (patient’s own feces; n = 15).

Disclosures: This study was funded by Helse Vest, Norway. The authors declared no conflicts of interest.

Key clinical point: Modest conformation exists between subjective reporting of the Bristol Stool Form Scale (BSFS) and fecal consistency measured by stool water content in irritable bowel syndrome (IBS), warranting caution when using BSFS reporting for subtyping IBS.

Major finding: BSFS scores significantly correlated with stool water content (correlation coefficient [r] 0.36, P < .0001); however, 77% of stool samples referred as BSFS 1-2 had a water content of ≤68.5% and 52.0% of samples referred as BSFS 6-7 had a water content of ≥78%. Sensitivity and specificity for BSFS 1-2 were 32% and 94%, respectively, and those for BSFS 6-7 were 37% and 93%, respectively.

Study details: The data come from a subanalysis of a previous randomized three-way crossover trial including 110 participants with severe-to-moderate IBS who underwent 1-week provocation with fermentable oligosaccharides, disaccharides, monosaccharides, and polyols; gluten; or placebo.

Disclosures: This study was funded by Formas and the Swedish Research Council. The authors declared no conflicts of interest.
