AI Article Synopsis
- - The study investigates the effects of temporarily stopping milking and administering estradiol (E2) to treat mastitis in dairy cows, focusing on the antimicrobial properties in goat milk.
- - Goats treated with E2 showed a significant decrease in milk yield but higher levels of antimicrobial components like cathelicidin-2, IgA, and lactoferrin compared to the control group.
- - These findings suggest that combining milking cessation with E2 might enhance the milk's immune properties and could be a potential alternative to antibiotics for mastitis treatment, pending further research.
Article Abstract
A temporary cessation of milking is widely used in Japan to treat mastitis in dairy cows. Exogenous administration of estradiol (E2) is known to inhibit milk production in dairy cows. Therefore, we aimed to evaluate the effects of the temporary cessation of milking in combination with E2 administration on the antimicrobial components of goat milk. Twelve goats, divided into two groups-with and without E2 injection (E2 and control group, respectively), were subjected to cessation of milking in both udder halves for 3 d (day 0-2). Milk yield in the E2 group was significantly lower than that in the control group on days 7 to 10. The concentrations of cathelicidin-2, IgA, and lactoferrin in the E2 group were significantly higher than those in the control group. These results suggest that the temporary cessation of milking with simultaneous E2 administration leads to a higher concentration of certain antimicrobial components in milk than that observed after using cessation of milking alone. Thus, this combination may contribute to a stronger innate immune system and a faster recovery from mastitis, and might prove to be an alternative to antibiotic treatment upon further research.

Objectives: Sudden unexpected infant death (SUID) occurs disproportionately among opioid exposed newborns (OENs) compared to those unexposed. The extent that primary caregivers of OENs adhere to SUID-reducing infant care practices is unknown. We examined rates of SUID-reducing practices (smoking cessation, breastfeeding, and safe sleep [supine sleep, room-sharing not bed-sharing, nonuse of soft bedding or objects]) in a pilot sample of caregivers of OENs.

Since nearly 40% of metabolic and bariatric surgery (MBS) patients are individuals with the ability to bear children, many may seek to become pregnant or may be currently lactating when seeking surgery. While many patients plan to breastfeed, MBS patients are at high risk for premature cessation of breastfeeding. Limited literature exists on the impact of MBS on lactation and there are no established guidelines to help clinicians support and educate MBS patients about breastfeeding.

Introduction: Although there are many known benefits of providing human milk to infants, breastfeeding-related pain is a significant reason for breastfeeding cessation. Breastfeeding-related pain is a unique experience due to breastfeeding's goal-directed purpose, repetitive nature, and socio-emotional reflections of successful parenting. Understanding how lactating parents cope with breastfeeding-related pain will inform clinical practice to encourage individuals to meet their lactation goals.

Tobacco smoke exposure remains a significant public health concern, particularly for lactating women and their infants. Despite widespread awareness of the harms of smoking during pregnancy, many women continue to smoke postpartum, directly impacting lactation success and infant health. Studies have shown that nicotine, the primary component of tobacco smoke, inhibits prolactin production and the milk ejection reflex, resulting in a decreased milk supply and poor breastfeeding outcomes.
