Breast pumps

Succinate dehydrogenase inhibitors (SDHIs) are widely-used fungicides, to which humans are exposed and for which putative health risks are of concern. In order to identify human molecular targets for these environmental chemicals, the interactions of 15 SDHIs with activities of main human drug transporters implicated in pharmacokinetics were investigated in vitro. 5/15 SDHIs, i.e., benzovindiflupyr, bixafen, fluxapyroxad, pydiflumetofen and sedaxane, were found to strongly reduce activity of the renal organic anion transporter (OAT) 3, in a concentration-dependent manner (with IC50 values in the 1...

Breastfeeding is a fundamental and biologically normal function with well-established benefits for both lactating parents and infants. Despite these benefits, physicians, particularly those in training, often face significant obstacles when attempting to meet their breastfeeding and pumping goals. In response to these challenges, the American Medical Women's Association (AMWA) and a diverse group of health care professionals have come together to advocate for comprehensive lactation support policies in medical learning environments and workplaces...

INTRODUCTION: Cyclin-dependent kinase (CDK) 4/6 inhibitors are cornerstones in the treatment of Hormone Receptor (HR) positive and Human Epidermal Growth factor (HER2) negative metastatic breast cancer. Given their widespread use in the metastatic setting and emerging use in the adjuvant setting, studying the drug-drug interactions (DDI) of these medications is of utmost importance. AREAS COVERED: This review provides key background information on the CDK4/6 inhibitors, palbociclib, ribociclib, and abemaciclib...

Necrotizing enterocolitis (NEC) is a life-threatening disease predominantly affecting premature and very low birth weight infants resulting in inflammation and necrosis of the small bowel and colon and potentially leading to sepsis, peritonitis, perforation, and death. Numerous research efforts have been made to better understand, treat, and prevent NEC. This review explores a variety of factors involved in the pathogenesis of NEC (prematurity, low birth weight, lack of human breast milk exposure, alterations to the microbiota, maternal and environmental factors, and intestinal ischemia) and reports treatment modalities surrounding NEC, including pain medications and common antibiotic combinations, the rationale for these combinations, and recent antibiotic stewardship approaches surrounding NEC treatment...

Pregnant individuals and infants in the US are experiencing rising morbidity and mortality rates. Breastfeeding is a cost-effective intervention associated with a lower risk of health conditions driving dyadic morbidity and mortality, including cardiometabolic disease and sudden infant death. Pregnant individuals and infants from racial/ethnic subgroups facing the highest risk of mortality also have the lowest breastfeeding rates, likely reflective of generational socioeconomic marginalization and its impact on health outcomes...

AIM: To evaluate the outcomes of a low-cost hospital-grade breast pump hire program for women experiencing financial hardship with infants in neonatal intensive care. DESIGN: A multi-method evaluation including data audits and surveys. METHODS: Twenty-four electric breast pumps were purchased and rented to mothers at a cost of $1/day. To be eligible, mothers needed to have given birth to an infant <32 weeks and/or <1500 g and self-identified as experiencing financial hardship...

Objective: To evaluate the impact of acupuncture as part of a traditional Chinese medicine (TCM) treatment plan on lactation and maternal well-being in pump-dependent mothers of hospitalized neonates during the first 30 days after delivery. Study Design: This single-center study was conducted in a level IV regional neonatal intensive care unit with access to integrative health services. Sixty-six mothers were prospectively enrolled in two nonparallel groups: (1) Standard lactation support and (2) standard lactation support augmented with acupuncture...

Background: Lactation induction in transgender women is a clinical and research priority in the field of breastfeeding medicine. To date, there are four case reports detailing successful induced lactation in transgender patients who wished to breastfeed. The Academy of Breast Feeding Medicine does not formally recommend a specific medication regimen for transgender patients due to lack of high-quality research. Case Presentation: A 50-year-old transgender woman with a hypercoagulable disorder who was able to lactate and breastfeed with novel hormone regimen management at a gender care clinic...

AIM: Few studies investigate factors that might influence the content of expressed breastmilk. This study aims to investigate the influence of the intervals between breastmilk pumping and the time of the day on protein and fat concentration in breastmilk. METHODS: Mothers of very preterm infants in a neonatal ward who expressed more than 400 mL per day were included. Expressed breastmilk was obtained from each mother over 30 h who were pumping at strictly planned and varying intervals: 2, 3, 4 and 6 h...

Conventional cancer chemotherapy regimens, albeit successful to some extent, suffer from some significant drawbacks, such as high-dose requirements, limited bioavailability, low therapeutic indices, emergence of multiple drug resistance, off-target distribution, and adverse effects. The main goal of developing implantable drug delivery systems (IDDS) is to address these challenges and maintain anti-cancer drugs directly at the intended sites of therapeutic action while minimizing inevitable side effects. IDDS possess numerous advantages over conventional drug delivery, including controlled drug release patterns, one-time drug administration, as well as loading and stabilizing poorly water-soluble chemotherapy drugs...

Fatty acid synthase (FASN), the sole cytosolic enzyme responsible for de novo palmitate synthesis in mammalian cells, has been associated with poor prognosis in cancer and shown to cause drug and radiation resistance by upregulating DNA-damage repair via suppression of p65 expression. Targeting FASN by repurposing proton pump inhibitors has generated impressive outcomes in triple negative breast cancer patients. While p65 regulation of DNA damage repair was thought to be due to its suppression of PARP1 gene transcription, the mechanism of FASN regulation of p65 expression was unknown...

Multidrug resistance 1 (MDR1) is a transmembrane transporter on the cell membrane. As an ATP-dependent efflux pump, MDR1 is mainly responsible for the adsorption, distribution, metabolism, excretion and transportation of anticancer drugs to cancer cells. Mutations of the MDR1 gene may be associated with the incidence of cancer. In the past decade, associations found between the MDR1 rs1045642 polymorphism and breast cancer have been inconsistent and inconclusive. Therefore, the present study performed a meta-analysis including studies published up until August 16, 2023 to systematically evaluate the association between the MDR1 rs1045642 polymorphism and breast cancer risk...

BACKGROUND: We present a case of non-puerperal induced lactation in transgender woman. Medical literature on lactation induction for transgender women is scarce, and the majority of literature and protocols on lactation induction is based on research in cisgender women. Healthcare professionals may lack the precise knowledge about lactation induction and may therefore feel insecure when advice is requested. Subsequently, there is a rising demand for guidelines and support. METHODS: Patient medical record was consulted and a semi-structured interview was conducted to explore the motive for lactation induction, the experience of lactation induction, and to gather additional information about the timeline and course of events...

BACKGROUND: Emergency Medicine (EM) physicians routinely treat breastfeeding patients. Physicians frequently recommend pumping and dumping milk for perceived safety risks. We hypothesized that the majority of the most commonly ordered medications in the emergency department (ED) are safe for breastfeeding patients. Accordingly, we performed a comprehensive safety analysis of the commonly ordered medications and provided an algorithm for EM physicians to utilize when treating breastfeeding patient in the ED...

We performed a prospective Internet survey study of anesthesiologists lactating in 2022 or 2023. Approximately half (48%, 75 of 156) lacked convenient dedicated lactation space and approximately half (55%, 86 of 155) used a wearable breast pump. The vast majority using a wearable pump did so in clinical settings, including operating rooms (88%, 76 of 86). When using during cases, approximately half reported that milk production was sufficient to substitute for lactation pumping sessions (52%, 39 of 75). Based on probability distributions of surgical times, future research can evaluate the usefulness of wearable pumps based on the objective of reducing anesthesiologists' durations of lactation sessions to <15 minutes...

Upregulation of the multidrug efflux pump ABCB1/MDR1 (P-gp) and the anti-apoptotic protein BIRC5/Survivin promotes multidrug resistance in various human cancers. GDC-0152 is a DIABLO/SMAC mimetic currently being tested in patients with solid tumors. However, it is still unclear whether GDC-0152 is therapeutically applicable for patients with ABCB1-overexpressing multidrug-resistant tumors, and the molecular mechanism of action of GDC-0152 in cancer cells is still incompletely understood. In this study, we found that the potency of GDC-0152 is unaffected by the expression of ABCB1 in cancer cells...

Background: Primary low milk supply (PLMS) prevents mothers from producing sufficient milk to breastfeed exclusively. However, limited evidence exists regarding women's experiences of breastfeeding with PLMS. Objective: This article aims to investigate the emotional experiences of mothers breastfeeding with PLMS in the first 3 months postpartum. Materials and Methods: The study was conducted in Ireland and used a phenomenological methodology to investigate the lived experiences of breastfeeding mothers with PLMS...

Breast cancer begins in the breast cells, mainly impacting women. It starts in the cells that line the milk ducts or lobules responsible for producing milk and can spread to nearby tissues and other body parts. In 2020, around 2.3 million women across the globe received a diagnosis, with an estimated 685,000 deaths. Additionally, 7.8 million women were living with breast cancer, making it the fifth leading cause of cancer-related deaths among women. The mutational changes, overexpression of drug efflux pumps, activation of alternative signalling pathways, tumour microenvironment, and cancer stem cells are causing higher levels of drug resistance, and one of the major solutions is to identify multitargeted drugs...
