Gestational weight gain and unplanned or emergency cesarean delivery in the United States.

Background: In the United States, the rates of cesarean delivery are well above the World Health Organization recommended target. Although obesity is a widely established risk factor for cesarean delivery, there is limited population-based research that examines the relationship between gestational weight gain and cesarean delivery.

Objective: To determine the association between gestational weight gain and unplanned or emergency cesarean delivery.

The Moderating Effect of Urban Versus Rural Residence on the Relationship Between Type of Birth Attendant and Early Initiation of Breastfeeding in Ghana.

Background: Early initiation of breastfeeding increases the likelihood of longer duration of breastfeeding. Factors associated with breastfeeding include maternal sociodemographic, behavioral and health-related characteristics, infant health characteristics, and perinatal factors. Research aim: This study aimed to determine the association between type of birth attendant and early initiation of breastfeeding among women in Ghana.

Hormonal contraceptive use and vitamin A deficiency among women in Tanzania.

Objective: To examine the association between hormonal contraceptive use and vitamin A deficiency among women in Tanzania.

Association Between Risky Sexual Behavior and Cervical Cancer Screening Among Women in Kenya: A Population-Based Study.

Women residing in Eastern Africa are disproportionately affected by cervical cancer. Previous studies have identified risky sexual behavior as a major risk factor for cervical cancer. However, population-based studies examining the relationship between sexual behavior and cervical cancer screening are currently lacking.

Association Between WIC Enrollment and Exclusive Breastfeeding at 3 Months Postpartum Among Low-Income Mothers.

Context: Existing literature suggests participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in the prenatal and postnatal periods is associated with lower rates of breastfeeding among WIC-eligible mothers. However, minimal research has been published on the association between WIC enrollment and exclusive breastfeeding.

Objective: To examine the association between WIC exposure and exclusive breastfeeding at 3 months postpartum.

Association Between Method of Delivery and Exclusive Breastfeeding at Hospital Discharge.

Context: Studies have shown that exclusive breastfeeding at hospital discharge is associated with longer duration of breastfeeding. Method of delivery (MOD) is a barrier that may hinder breastfeeding practices. However, research examining the association between MOD and exclusive breastfeeding at hospital discharge is lacking.

Water cucurbituril rim: a fierce competition for guest solvation.

The impact of remote substituents on the affinity of cucurbit[]urils (CB[]) towards a homologous series of guests, which differ from one another only by a single substituent, and adopt the same geometry within the cavity of the macrocycle, is presented for the first time, and is used to decipher the competition between water and the carbonylated portal of CB[7] for the stabilization of positively charged guests. Binding affinities of CB[7] towards substituted -benzyl-trimethylsilylmethylammonium cations relative to the unsubstituted member (X = H) range from 0.9 (X = CH) to 3.
