Objective: Although there has been much debate on whether women should be allowed to eat and drink during labour, little scientific data are available on the effects of caloric intake on the course of labour.
Design: Double-blind, randomised, placebo controlled.
Setting: Leyenburg Hospital, The Hague, The Netherlands.
Population: Two hundred and one consecutive nulliparous women, pregnant of a single fetus in cephalic presentation.
Methods: All women were included in early labour (2cm-4cm of cervical dilatation) and were allowed to drink at will.
Main Outcome Measures: The duration of labour, the need for augmentation and pain medication and the incidence of abdominal and vaginal instrumental deliveries.
Results: Drinking of carbohydrate solutions was well tolerated, but did not show any beneficial effects regarding labour outcome when compared with the control group. In the carbohydrate group, a higher caesarean section rate was observed (RR 2.9, 95% CI 1.29-6.54).
Conclusions: Women in the carbohydrate group had worse labour outcome. It is unclear whether a statistical coincidence, a negative effect of the carbohydrate intake or an incorrect carbohydrate intake strategy is responsible for these results. Further studies are necessary before any definite conclusion can be drawn.

Rectangular Repetitive Transcranial Magnetic Monophasic vs Biphasic Stimulation for Major Depressive Disorder: A Randomized Controlled Pilot Trial.
Neuromodulation

Department of Psychiatry and Behavioral Sciences, Division of Child and Adolescent Psychiatry, Weill Institute for Neurosciences, University of California San Francisco, San Francisco, CA, USA.
Objectives: Biphasic sinusoidal repetitive transcranial magnetic stimulation (rTMS) is a noninvasive brain stimulation treatment that has been approved by the US Food and Drug Administration for treatment-resistant depression (TRD). Recent advances suggest that standard rTMS may be improved by altering the pulse shape; however, there is a paucity of research investigating pulse shape, owing primarily to the technologic limitations of currently available devices. This pilot study examined the feasibility, tolerability, and preliminary efficacy of biphasic and monophasic rectangular rTMS for TRD.

Nasal spray treatments that inhibit the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) entry into nose and nasopharynx at early stages can be an appropriate approach to stop or delay the progression of the disease. We performed a prospective, randomized, double-blind, placebo-controlled, parallel-group, multicentric, phase II clinical trial comparing the rate of hospitalization due to COVID-19 infection between azelastine 0.1% nasal spray and placebo nasal spray treatment groups.

Objectives: This study aimed to evaluate the immunogenicity and safety of a 13-valent pneumococcal polysaccharide conjugate vaccine (CRM197/TT) (PCV13i) in infants.
Methods: A total of 1200 infants were randomly assigned to either the experimental PCV13i group or the control PCV13 group in a 1:1 ratio. Each group received a three-dose series of the vaccine at 2, 4, and 6 months of age, followed by a booster dose at 12-15 months.

Background: This study aimed to compare the effects of a carbohydrate (CHO) hydrogel with (ALG-CP) or without (ALG-C) branched-chain amino acids, and a CHO-only non-hydrogel (CON), on cycling performance. The hydrogels, encapsulated in an alginate matrix, are designed to control CHO release, potentially optimising absorption, increasing substrate utilisation, and reducing gastrointestinal distress as well as carious lesions.
Methods: In a randomised, double-blinded, crossover trial, 10 trained male cyclists/triathletes completed three experimental days separated by ~6 days.

Background/objective: This study aimed to investigate the efficacy of oral probiotic supplementation in preventing vulvovaginal infections (VVIs) in pregnant women, specifically focusing on abnormal vaginal flora (AVF), bacterial vaginosis (BV), and vulvovaginal candidiasis (VVC).
Methods: A multicenter-prospective-randomized, double-blind, placebo-controlled trial was conducted during 2016-2019. Women with normal vaginal flora (Nugent score < 4 and no candida) were divided into a research group, receiving 2 capsules/day of oral probiotic formula containing , , , , , and , or a control group, receiving a placebo until delivery.
