Dietary Intake of Nutrients Involved in Serotonin and Melatonin Synthesis and Prenatal Maternal Sleep Quality and Affective Symptoms.

Poor sleep quality and psychological distress in pregnancy are important health concerns. Serotonin and melatonin levels may underlie variation in these adverse outcomes. In this study, we examined dietary nutrients involved in serotonin and melatonin synthesis in relation to maternal sleep quality and affective symptoms during pregnancy.

Validation of the Weight-Related Eating Questionnaire in pregnancy.

The Weight-Related Eating Questionnaire (WREQ), designed for assessing distinct constructs of dietary restraint and disinhibition-related eating behaviors, has not been validated in pregnancy. This secondary data analysis aimed to evaluate the WREQ's psychometrics in a diverse sample of pregnant women from the eMoms randomized controlled trial (N = 1399), randomly split for exploratory (EFA, n = 691) and confirmatory factor analysis (CFA, n = 708). Cronbach's alpha and corrected item-total correlation was used to examine internal consistency reliability.

Experiences of loss of control eating in women after bariatric surgery: A qualitative study.

Objective: Loss of control (LOC) eating following bariatric surgery remains insufficiently understood, reflected in a lack of clear conceptualization, valid measurements, and effective treatments. This study explored patients' perspectives on LOC eating post-bariatric surgery, focusing on the relevance of the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) indicators of impaired control, and patients' experiences before (precipitating factors), during (eating patterns, perpetuating factors), and after the episodes (strategies used to stop eating).

Methods: This was a qualitative study using descriptive phenomenology.

Crystallization of Form II Paracetamol with the Assistance of Carboxylic Acids toward Batch and Continuous Processes.

Form II paracetamol has captured the interest of researchers due to its improved compressibility. However, its low stability has made it difficult to be produced on a large scale with good reproducibility. In the present study, the selective polymorphic formation of paracetamol was carried out by cooling crystallization with four types of additives: adipic acid, fumaric acid, oxalic acid, and succinic acid.

Influence of Appetite and Perceived Ability to Control Cravings on Excessive Gestational Weight Gain.

Objective: To explore whether appetite is associated with gestational weight gain (GWG) and to assess the effect of perceived ability to control cravings on excessive GWG.

Design: Secondary data analysis.

Setting: Rochester, New York, United States.

A Novel Hydrate Form of Sodium Dodecyl Sulfate and Its Crystallization Process.

A novel hydrate form of sodium dodecyl sulfate (SDS) was firstly discovered through a hydrate screening with the use of organic solvents, while SDS is generally prepared solely in aqueous media. Surprisingly, a novel SDS hydrate form with needle-shaped crystals produced by adding acetonitrile to a 20 wt % SDS aqueous solution at a ratio of 3:1 (v/v) and further cooling to around 5 °C could be found with a trace amount in one of the two purchased SDS products that we examined. After comprehensive solid-state characterizations by powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR), Raman spectroscopy, dynamic vapor sorption (DVS), and elemental analysis (EA), it is also successfully made directly from the synthesis of SDS through esterification and saponification.

Associations between Dietary Patterns and Inflammatory Markers during Pregnancy: A Systematic Review.

Elevated inflammation in pregnancy has been associated with multiple adverse pregnancy outcomes and potentially an increased susceptibility to future chronic disease. How maternal dietary patterns influence systemic inflammation during pregnancy requires further investigation. The purpose of this review was to comprehensively evaluate studies that assessed dietary patterns and inflammatory markers during pregnancy.

Reproducible Crystallization of Sodium Dodecyl Sulfate·1/8 Hydrate by Evaporation, Antisolvent Addition, and Cooling.

Sodium dodecyl sulfate (SDS)·1/8 hydrate (NaCHSO·1/8HO) crystals were successfully produced by evaporation, antisolvent addition, cooling crystallization, and isothermal aging in a common stirred tank. A clear 33.3 wt % SDS aqueous solution was concentrated by evaporation to a 60 wt % coagel consisting of numerous SDS hydrates and water.

Continuous Preparation of 1:1 Haloperidol-Maleic Acid Salt by a Novel Solvent-Free Method Using a Twin Screw Melt Extruder.

Salts are generally prepared by acid-base reaction in relatively large volumes of organic solvents, followed by crystallization. In this study, the potential for preparing a pharmaceutical salt between haloperidol and maleic acid by a novel solvent-free method using a twin-screw melt extruder was investigated. The pH-solubility relationship between haloperidol and maleic acid in aqueous medium was first determined, which demonstrated that 1:1 salt formation between them was feasible (pH 4.
