RESUMEN
STUDY DESIGN: Narrative review. OBJECTIVES: To evaluate the availability and quality of breastfeeding guidelines for women with spinal cord injury (SCI). SETTING: International Collaboration on Repair Discoveries (ICORD), Department of Medicine, Vancouver, BC. METHODS: An environmental scan restricted to English language literature was performed to identify existing postpartum and breastfeeding guidelines. Guidelines were evaluated using a structured, validated tool (AGREE II) by 13 appraisers [medical/research experts (n = 10) and those with lived experience (n = 3)] from Vancouver and two international sites. Seven guidelines were evaluated across Domain 1 of the AGREE II tool to determine if they were applicable to mothers with SCI/physical disabilities. Domains 2 to 7 were evaluated if the guideline made mention of the SCI population. RESULTS: Of the seven guidelines evaluated, only one mentioned SCI (Postpartum Care in SCI from BC Women's Hospital). Other guidelines were excluded from further evaluation as they did not address the issue of breastfeeding in women with SCI. The overall scaled score for this guideline was 34.5%. There was significant variability between domains but no AGREE II domain scored greater than 50%, indicating substantial limitations. CONCLUSIONS: Current breastfeeding guidelines are not targeted to persons with SCI. The one guideline that made mention of women with SCI had significant global deficits. This highlights the importance of developing guidelines for health care providers focused specifically on women with SCI to support and optimize breastfeeding in this unique population for the benefit of mother and infant across the lifespan.

The World Health Organization (WHO) recommends that infants be breastfed exclusively for the first 6 months of age. However, there are few resources available on the effects a spinal cord injury (SCI) can have for breastfeeding mothers. It is difficult to find information to address the unique challenges women with SCI experience when planning or trying to breastfeed. Our international team, including women with SCI, health care providers, and SCI researchers, aims to address the information gap through the creation of this consumer guide. The purpose of this consumer guide is to share the most common issues women with SCI experience during breastfeeding and provide information, practical suggestions, recommendations, and key resources in lay language. General information about breastfeeding is available on the internet, in books, or from friends and health care providers. We do not intend to repeat nor replace general breastfeeding information or medical advice. Breastfeeding for mothers with SCI is complex and requires a team of health care providers with complementary expertise. Such a team may include family physician, obstetrician, physiatrist, neurologist, occupational and physical therapist, lactation consultant, midwife, and psychologist. We hope this consumer guide can serve as a quick reference guide for mothers with SCI planning of trying to breastfeed. This guide will also be helpful to health care providers as an educational tool.

The World Health Organization (WHO) recommends that children be breastfed exclusively for the first 6 months of age. This recommendation may prove challenging for women with spinal cord injury (SCI) who face unique challenges and barriers to breastfeeding due to the impact of SCI on mobility and physiology. Tailored provision of care from health care professionals (HCPs) is important in helping women navigate these potential barriers. Yet, HCPs often lack the confidence and SCI-specific knowledge to meet the needs of mothers with SCI. An international panel of clinicians, researchers, consultants, and women with lived experience was formed to create an accessible resource that can address this gap. A comprehensive survey on breastfeeding complications, challenges, resources, and quality of life of mothers with SCI was conducted, along with an environmental scan to evaluate existing postpartum guidelines and assess their relevance and usability as recommendations for breastfeeding after SCI. Building on this work, this article provides evidence-based recommendations for HCPs, including but not limited to general practitioners, obstetricians, pediatricians, physiatrists, lactation consultants, nurses, midwives, occupational therapists, and physiotherapists who work with prospective and current mothers with SCI.

Objective: To examine the prevalence of postpartum depression (PPD) and postpartum anxiety (PPA) in mothers with spinal cord injury (SCI).Design: Retrospective, cross-sectional study.Setting: Online multi-national study.Participants: We surveyed an international sample of 102 women who gave birth following cervical SCI (C1-C8, n = 30), upper thoracic SCI (T1-T6, n = 12) or lower level SCI (T7 & below, n = 60). Participants were primarily from Canada and Sweden, and mean age at childbirth was 30 ± 6 years.Outcome Measures: Subscales from the Pregnancy Risk Assessment Monitoring System (PRAMS) were used to measure PPD (PRAMS-3D) and PPA (PRAMS-2A).Results: PPD and PPA were most prevalent in women with cervical SCI, followed by upper thoracic SCI then lower SCI. Self-reported PPD was more prevalent than clinically diagnosed PPD in women with cervical SCI (P = 0.03) and upper thoracic SCI (P = 0.03). With cervical SCI, 75% of women diagnosed with MDD before pregnancy scored >9 on the PRAMS PPD subscale, indicating clinically relevant PPD. However, only 10% were diagnosed with PPD. Of women with lower SCI diagnosed with MDD before pregnancy, 25% had a clinically relevant score for self-reported PPD; 7% were diagnosed.Conclusions: This is currently the largest study examining PPD and PPA after SCI. Clinicians should be aware that mothers with SCI (particularly high-level SCI) may have increased risk of PPD and PPA. PPD is poorly understood in women with SCI and may even be underdiagnosed. SCI-related risk factors for PPD and PPA should be explored.

Background: In North America, there are currently no clearly defined standards of care for women with spinal cord injury (SCI) during the perinatal periods of preconception, pregnancy, labour/delivery, and postpartum. Women with SCI and their partners say resources specific to their needs are hard to find. Little evidence-informed research exists to guide clinicians in the care of women with SCI during pregnancy. Objectives: To further explore these gaps in knowledge and practices for perinatal care for women with SCI, a 1-day workshop was held in Vancouver, British Columbia (BC), Canada in November 2013. Methods: Twenty-nine attendees included women with SCI, SCI-community service providers, researchers, and health care providers from maternal/fetal medicine, rehabilitation, anesthesiology, and psychiatry. A pre-meeting online survey of stakeholders elucidated 3 themes: lack of knowledge for both consumers and care providers, gaps in access to services and information, and a need for collaboration throughout the perinatal journey. The workshop addressed issues of care providers' lack of knowledge of nonmedical issues during the perinatal period, physical and attitudinal barriers to access to care for women with SCI, and the need for better collaboration and communication between care providers, the latter potentially initiated by providing information to care providers through the women with SCI themselves. Results: Content experts attending the workshop collectively made recommendations for knowledge generation and research priorities, clinical application priorities, and the need for policy and guideline development in this field. Conclusion: Two information sources for women have since been developed and are available online.

The conditioned taste aversion (CTA) is routinely used to assess the aversive consequences of anorexic agents, including potential pharmacological therapies for obesity. In a typical CTA paradigm, rats briefly sampling a novel tastant (e.g., saccharin) are acutely administered with toxin (e.g., lithium chloride, LiCl). After as few as one taste-toxin pairing, rats will reliably avoid the novel tastant. This paradigm is frequently used for the assessment of possible aversive consequences of drugs that are candidates for pharmacological therapies. The degree to which the drug supports development of a CTA is interpreted as an index of its aversive properties. Difficulties with previous work include the inability to assess affects on food intake and CTA simultaneously, particularly during chronic drug administration. We report here two novel CTA paradigms for the assessment of appetitive and aversive consequences of anorexic agents, simultaneously. In the first experiment, animals receive an intraoral infusion of a novel and highly palatable tastant immediately prior to administration of increasing doses of LiCl. In the second experiment, rats were implanted intraperitoneally with osmotic minipumps that chronically delivered a low dose of LiCl for 7 days. LiCl did not affect short or long term food intake in either experiment. However, LiCl did support the development of a CTA in both paradigms. These results suggest that both the appetitive and aversive consequences of anorexic agents can be assessed simultaneously during either acute or chronic drug administration.

Behavioral therapies aimed at reducing excess body fat result in limited fat loss after dieting. To understand the causes for maintenance of adiposity, high-fat (HF) diet-induced obese (DIO) mice were switched to a low-fat chow diet, and the effects of chow on histological and molecular alterations of adipose tissue and metabolic parameters were examined. DIO mice reduced and stabilized their body weights after being switched to chow (HF-chow), but retained a greater amount of adiposity than chow-fed mice. Reduction in adipocyte volume, not number, caused a decrease in fat mass. HF-chow mice showed normalized circulating insulin and leptin levels, improved glucose tolerance, and reduced inflammatory status in white adipose tissue (WAT). Circulating leptin levels corrected for fat mass were lower in HF-chow mice. Leptin administration was used to test whether reduced leptin level of HF-chow mice inhibited further fat loss. Leptin treatment led to an additional reduction in adiposity. Finally, HF-HF mice had lower mRNA levels of beta(3) adrenergic receptor (beta(3)-AR) in epididymal WAT (EWAT) compared to chow-fed mice, and diet change led to an increase in the WAT beta(3)-AR mRNA levels that were similar to the levels of chow-fed mice, suggesting an elevation in sympathetic activation of WAT during diet switch relative to HF-HF mice leading to the reduced leptin level and proinflammatory cytokine content. In summary, HF-chow mice were resistant to further fat loss due to leptin insufficiency. Diet alteration from HF to low fat improved metabolic state of DIO mice, although their adiposity was defended at a higher level.

Analyses were performed to evaluate the roles of the beta1- and beta2-adrenergic receptors in the skeletal muscle hypertrophy and anti-atrophy response to the beta-adrenergic agonist, clenbuterol. Treatment of wild-type mice with clenbuterol resulted in statistically significant hypertrophy of the innervated tibialis anterior and medial gastrocnemius muscles and inhibition of denervation-induced atrophy of these muscles. Treatment of beta1-adrenergic receptor knockout mice with clenbuterol also resulted in statistically significant hypertrophy of the innervated tibialis anterior and medial gastrocnemius muscles and inhibition of denervation-induced atrophy of these muscles. In contrast, in beta2-adrenergic receptor knockout mice and in mice lacking both the beta1- and beta2-adrenergic receptors, clenbuterol treatment did not result in hypertrophy of the innervated tibialis anterior and medial gastrocnemius muscles, nor did it inhibit denervation-induced atrophy in these muscles. Together these data demonstrate that the beta2-adrenergic receptor is responsible for both the skeletal muscle hypertrophy and anti-atrophy effects of the beta-adrenergic agonist clenbuterol.
