RESUMO

BACKGROUND: The internet has become a place of increased risk of abuse, including sexual abuse, for young people (YP). One potential risk factor to online abuse and exploitation is the ability to mentalise. We developed the i-Minds app, a mentalisation-based digital health intervention (DHI) for YP who have experienced technology assisted sexual abuse (TASA), which we tested in a clinical feasibility trial. Nested within the trial was a qualitative implementation study with clinicians who referred to the trial. OBJECTIVE: To explore the barriers and enablers to the future integration of i-Minds into clinical practice. PARTICIPANTS AND SETTING: Twelve HCPs were recruited from across two trial recruitment sites (Manchester and Edinburgh). METHODS: Semi-structured interviews were informed by Normalisation Process Theory (NPT). Framework analysis was used; transcripts were coded deductively to NPT constructs. RESULTS: Practitioners were positive about the need for, and added value of, the i-Minds app over existing interventions, including other DHIs. While they felt confident with the app, concerns remained around the safety of using the app without practitioner support. i-Minds promoted changes in practitioners' work and impacted online behaviour of YP. There was an identified need for further training and organisational support. CONCLUSIONS: Practitioners are aware of TASA but have limited knowledge, skills and tools to work with TASA in clinical practice with YP. There is a need for awareness raising and education about TASA and DHI. i-Minds offers a theory-informed DHI for working with YP exposed to TASA that is acceptable to practitioners and YP.

RESUMO

BACKGROUND: Black and brown birthing people experience persistent disparities in adverse maternal health outcomes, partially due to inadequate perinatal care. The goal of this study is to design and evaluate a patient-centered intervention for obstetric patients with one or more cardiometabolic risk factors for severe maternal morbidity [gestational diabetes, diabetes mellitus, hypertensive disorders of pregnancy (chronic hypertension, preeclampsia, eclampsia, or gestational hypertension), or preconception obesity (BMI > 30)] to promote postpartum visit attendance. METHODS: To address identified unmet needs for postpartum support and barriers to postpartum care, we developed 20 thematic postpartum planning modules, each with corresponding patient educational materials, community resources, care coordination protocols, and clinician support tools (decision aids, electronic medical record prompts and fields). During prenatal care encounters, a research coordinator delivers the educational content (in English or Spanish), facilitates the participant's planning and shared decision-making, provides the participant with resources, and documents decisions in the electronic medical record. We will randomize 320 eligible patients with a 1:1 ratio to the intervention or standard prenatal care and evaluate the impact on postpartum visit attendance at 4-12 weeks and secondary outcomes (postpartum mental health, perceived future maternal and cardiometabolic risk, contraceptive use, primary care use, readmission, and patient satisfaction with care). DISCUSSION: Through engagement with patients and community stakeholders, we developed a guideline-based, locally tailored intervention to address drivers of engagement with postpartum care for high-risk obstetric patients. If demonstrated to be effective, the educational materials and electronic medical record based-tool can be adapted to other settings. TRIAL REGISTRATION: This trial was registered on ClinicalTrials.gov (NCT05430815) on June 23, 2022.

RESUMO

BACKGROUND: There is growing evidence that Technology Assisted Sexual Abuse (TASA) represents a serious problem for large numbers of children. To date, there are very few evidence-based interventions available to young people (YP) after they have been exposed to this form of abuse, and access to support services remains a challenge. Digital tools such as smartphones have the potential to increase access to mental health support and may provide an opportunity for YP to both manage their distress and reduce the possibility of further victimization. The current study explores the acceptability of a digital health intervention (DHI; the i-Minds app) which is a theory-driven, co-produced, mentalization-based DHI designed for YP aged 12-18 who have experienced TASA. METHODS: Semi-structured interviews were conducted with 15 YP recruited through Child and Adolescent Mental Health Services, a Sexual Assault Referral Centre and an e-therapy provider who had access to the i-Minds app as part of a feasibility clinical trial. Interviews focused on the acceptability and usability of i-Minds and were coded to themes based on the Acceptability of Healthcare Interventions framework. RESULTS: All participants found the i-Minds app acceptable. Many aspects of the app were seen as enjoyable and useful in helping YP understand their abuse, manage feelings, and change behavior. The app was seen as usable and easy to navigate, but for some participants the level of text was problematic and aspects of the content was, at times, emotionally distressing at times. CONCLUSIONS: The i-Minds app is useful in the management of TASA and helping change some risk-related vulnerabilities. The app was designed, developed and evaluated with YP who had experienced TASA and this may account for the high levels of acceptability seen. TRIAL REGISTRATION: The trial was registered on the ISRCTN registry on the 12/04/2022 as i-Minds: a digital intervention for young people exposed to online sexual abuse (ISRCTN43130832).

RESUMO

INTRODUCTION: In the United States (US), pregnant females who use substances face increased morbidity and mortality risks compared to non-pregnant females. This study provides a national snapshot of substance use and treatment characteristics among US reproductive-aged females, including those who are pregnant. METHODS: Our sample included females aged 15-44 years (n=97,830) from the 2015-2019 National Survey on Drug Use and Health (NSDUH) data. We calculated weighted percentages of past-month alcohol or drug use and past-year substance use disorder (SUD), stratified by pregnancy status. We also calculated weighted percentages of past-year treatment setting and payer. Pearson chi-square tests were conducted to determine if percentages were statistically significantly different. RESULTS: Compared to non-pregnant females, pregnant females had lower prevalence of past-month illicit drug use excluding cannabis (1.6% vs. 4.3%, p<0.01), cannabis use (5.3% vs. 12.5%, p<0.01), binge drinking (4.5% vs. 29.3%, p<0.01) and past-year SUD (7.1 vs. 8.8%, p<0.01). Less than 13% of females with SUD received treatment regardless of pregnancy status, but treatment use was higher among pregnant females compared to non-pregnant females (12.8% vs. 10.5%). However, there were no statistically significant differences in past-year treatment use, setting, or treatment payer. DISCUSSION: The prevalence of substance use and SUD was lower among pregnant females compared to non-pregnant females in 2015-2019. Low uptake of substance use treatment suggests that barriers exist to treatment-seeking among reproductive-aged women. Further exploration of stigma, payment, and access to treatment, and how they differ by pregnancy status, is needed.

RESUMO

BACKGROUND: Liver biopsy is the gold standard to evaluate hepatic fibrosis; however, it has many drawbacks, especially in patients with severe obesity. Noninvasive testing such as the FIB-4 score is increasingly being used as the initial screening tool to identify patients at risk for advanced fibrosis. The broader applicability of FIB-4 and the precision of its cutoff values remain uncertain in metabolic dysfunction-associated steatotic liver disease and patients with severe obesity. Our study explored the correlation between FIB-4 scores and intraoperative liver biopsy in patients with severe obesity undergoing bariatric surgery. METHODS: A total of 632 patients with severe obesity underwent preoperative vibration-controlled transient elastography and intraoperative liver biopsy during bariatric surgery from January 2020 to August 2021. Variables collected included patient demographics, laboratory values, abdominal ultrasound, vibration-controlled transient elastography, and liver biopsy results. ANOVA 1-way test, χ2 tests, and Fisher exact tests were used for quantitative and qualitative variables, respectively. The 95% CIs for the mean FIB-4 scores were used to generate surrogate cutoff values. The proposed FIB-4 cutoffs for F0-1, F2, F3, and F4 were 0.62 (CI: 0.59, 0.64), 0.88 (0.74, 1.01), 1.24 (0.94, 1.54), and 1.53 (0.82, 2.24), respectively. Area under the curve (AUC) methods were used to compare traditional to proposed cutoff values. RESULTS: Applying the traditional FIB-4 cutoffs to approximate advanced fibrosis yielded an AUC of 0.5748. Use of the proposed FIB-4 cutoffs increased the AUC to 0.6899. The proposed FIB-4 cutoffs correctly identified 40 patients with biopsy-proven advanced fibrosis (F3-F4), all of which would have been missed using traditional cutoffs. CONCLUSION: Our study revealed that the use of the currently accepted FIB-4 cutoffs as the screening modality for identifying patients with advanced fibrosis due to metabolic dysfunction-associated steatotic liver disease is insufficient and will result in missing patients with histologically confirmed advanced fibrosis. Use of the revised FIB-4 scores should be considered to diagnose patients with severe obesity at high risk of liver disease progression.

RESUMO

Advancements in 3-Dimensional (3D) culture models for studying disease have increased significantly over the last two decades, but fully understanding how these models represent in vivo still requires further investigation. The current study investigated differences in gene expression between a baseline sample and that maintained on a tissue-on-chip perfusion device for up to 96 h, with and without clinically-relevant doses of irradiation, to allow differentiation of model and treatment effects. Tumour tissue samples from 7 Head and Neck Squamous Cell Carcinomas (HNSCC) patients were sub-divided and either fixed immediately upon excision or maintained in a tissue-on-chip device for 48 and 96 h, with or without 2 Gray (Gy) or 10 Gy irradiation. Gene expression was measured using an nCounter® PanCancer Progression Panel. Differentially expressed genes between pre- and post-ex vivo culture, and control and irradiated samples were identified using nSolver software (version 4.0). The secretome from the tumour-on-chip was analysed for the presence of cytokines using a Proteome Profiler™ platform. Significant numbers of genes both increased (n = 6 and 64) and decreased (n = 18 and 58) in expression in the tissue maintained on-chip for 48 and 96 h, respectively, compared to fresh tissue; however, the irradiation schedule chosen did not induce significant changes in gene expression or cytokine secretion. Although HNSCC tissue maintained ex vivo shows a decrease in a large proportion of altered genes, 25% and 53% (48 and 96 h) do show increased expression, suggesting that the tissue remains functional. Irradiation of tumour tissue-on-chip needs to be conducted for longer time periods for specific gene changes to be observed, but we have shown, for the first time, the feasibility of using this perfusion platform for studying the genomic response of HNSCC tissue biopsies.

RESUMO

OBJECTIVE: The authors explored potential unintended consequences of Medicare policy changes in response to the COVID-19 pandemic for beneficiaries with behavioral health care needs. METHODS: The authors collected policies relevant to mental health and substance use care. Informed by a literature review conducted in spring 2022, the authors convened a modified Delphi panel with 13 experts in June 2022. The authors assessed expert consensus through panelist surveys conducted before and after the panel convened. RESULTS: Two policies that had a risk for unintended consequences for those with behavioral health care needs were identified. Panelists identified a discharge planning waiver as likely to decrease care access, care quality, and desirable outcomes and HIPAA enforcement discretion as likely to increase access to care and desirable outcomes (with some mixed effects on other outcomes) for Medicare beneficiaries with mental illness or substance use disorders. CONCLUSIONS: Policies implemented quickly during the pandemic did not always account for unintended consequences for beneficiaries with behavioral health care needs.

RESUMO

BACKGROUND: No evidence-based support has been offered to young people (YP) who have experienced technology-assisted sexual abuse (TASA). Interventions aimed at improving mentalization (the ability to understand the mental states of oneself and others) are increasingly being applied to treat YP with various clinical issues. Digital technology use among YP is now common. A digital intervention aimed at improving mentalization in YP who have experienced TASA may reduce the risk of revictimization and future harm and make YP more resilient and able to manage distress that might result from TASA experiences. OBJECTIVE: In this paper, we describe a protocol for determining the feasibility of the i-Minds trial and the acceptability, safety, and usability of the digital intervention (the i-Minds app) and explore how to best integrate i-Minds into existing routine care pathways. METHODS: This is a mixed methods nonrandomized study aimed to determine the feasibility, acceptability, safety, and usability of the intervention. Participants aged between 12 and 18 years who report distress associated with TASA exposure will be recruited from the United Kingdom from the National Health Service (NHS) Trust Child and Adolescent Mental Health Services, sexual assault referral centers, and a web-based e-therapy provider. All participants will receive the i-Minds app for 6 weeks. Coproduced with YP and a range of stakeholders, the i-Minds app focuses on 4 main topics: mentalization, TASA and its impact, emotional and mental health, and trauma. A daily prompt will encourage YP to use the app, which is designed to be used in a stand-alone manner alongside routine care. We will follow participants up after the intervention and conduct interviews with stakeholders to explore the acceptability of the app and trial procedures and identify areas for improvement. Informed by the normalization process theory, we will examine barriers and enablers relevant to the future integration of the intervention into existing care pathways, including traditional clinic-based NHS and NHS e-therapy providers. RESULTS: This study was approved by the Research Ethics Board of Scotland. We expect data to be collected from up to 60 YP. We expect to conduct approximately 20 qualitative interviews with participants and 20 health care professionals who referred YP to the study. The results of this study have been submitted for publication. CONCLUSIONS: This study will provide preliminary evidence on the feasibility of recruiting YP to a trial of this nature and on the acceptability, safety, and usability of the i-Minds app, including how to best integrate it into existing routine care. The findings will inform the decision to proceed with a powered efficacy trial.

RESUMO

Background: Studies have reported that the COVID-19 pandemic has led to an increase in alcohol consumption and alcohol-associated health problems in the general population. Our previous study documented a rise in severe alcohol-related hepatitis cases requiring inpatient admission in our hospital system in the early pandemic (2019 vs. 2020). This study assesses the rates of severe alcohol-related hepatitis in the latter part of the pandemic (2021). Methods: We performed a retrospective chart review via an electronic medical record to evaluate the number of cases of alcohol-related hepatitis in patients presenting to three community hospitals in Fresno, California, between 2019 (pre-pandemic) and 2021. A total of 547 patients were included in the study. We compared the demographics, clinical course, and outcomes of patients with alcohol-related hepatitis pre-pandemic (2019), early pandemic (2020), and during the later phase of the pandemic (2021). Results: The number of cases increased from 131 in 2019 to 201 in 2020 and 215 in 2021 (53% and 64% increase, respectively). The number of young patients (age <40 years) increased from 30 in 2019 to 61 in 2020 and 71 in 2021 (103% and 136% increase, respectively) (p = 0.13). The number of admissions of women increased from 24 in 2019 to 55 in 2020 and 67 in 2021 (129% and 179% increase, respectively) (p = 0.026). Deaths during hospitalization increased from 20 in 2019 to 26 in 2021 (p = 0.674). The number of rehospitalizations within 3 months increased 4.5 times from 18 in 2019 to 80 in 2021 (p < 0.001). Conclusion: Our study revealed that the admissions for alcohol-related hepatitis remained significantly above the pre-pandemic levels through the end of 2021. We believe this sustained increase in cases of alcohol-related hepatitis in our hospital system reflects a much larger national problem. Alcohol-related hepatitis is associated with significant morbidity, mortality, and societal cost. Urgent public health interventions are needed at a national level to prevent this rise in cases from becoming a new normal.

RESUMO

Most cases of melanoma found in the gastrointestinal tract are the result of metastasis. Although uncommon and only described in isolated case reports, primary gastric melanoma should be considered when patients present with vague gastrointestinal symptoms and a mass is identified on esophagogastroduodenoscopy or imaging. We describe a case of primary gastric balloon cell melanoma in a 73-year-old man who presented with melena. Given the high morbidity and mortality of gastric mucosal melanoma, early diagnosis and initiation of treatment can lead to improved outcomes and survival.

RESUMO

Small extracellular vesicles (sEVs) contain microRNAs (miRNAs) which have potential to act as disease-specific biomarkers. The current study uses an established method to maintain human thyroid tissue ex vivo on a tissue-on-chip device, allowing the collection, isolation and interrogation of the sEVs released directly from thyroid tissue. sEVs were analysed for differences in miRNA levels released from benign thyroid tissue, Graves' disease tissue and papillary thyroid cancer (PTC), using miRNA sequencing and quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) to identify potential biomarkers of disease. Thyroid biopsies from patients with benign tissue (n = 5), Graves' disease (n = 5) and PTC (n = 5) were perfused with medium containing sEV-depleted serum for 6 days on the tissue-on-chip device. During incubation, the effluents were collected and ultracentrifuged to isolate sEVs; miRNA was extracted and sequenced (miRNASeq). Out of the 15 samples, 14 passed the quality control and miRNASeq analysis detected significantly higher expression of miR-375-3p, miR-7-5p, miR-382-5p and miR-127-3p in the sEVs isolated from Graves' tissue compared to those from benign tissue (false discovery rate; FDR p < 0.05). Similarly, miR-375-3p and miR-7-5p were also detected at a higher level in the Graves' tissue sEVs compared to the PTC tissue sEVs (FDR p < 0.05). No significant differences were observed between miRNA in sEVs from PTC vs. those from benign tissue. These results were supported by Quantitative Reverse Transcriptase Polymerase Chain Reaction (qRT-PCR). The novel findings demonstrate that the tissue-on-chip technology is a robust method for isolating sEVs directly from the tissue of interest, which has permitted the identification of four miRNAs, with which further investigation could be used as biomarkers or therapeutic targets within thyroid disease.

RESUMO

Hepatitis C virus (HCV) is an ongoing global public health threat affecting millions worldwide. Increasing recognition of its impact and recent advances towards HCV prevention and cure have provided incentive for the World Health Organization to call for global elimination by 2030. The goal of therapy is to achieve a sustained virologic response (SVR-12), defined as undetectable HCV-RNA within 12 weeks after treatment completion. In 2011, approval was given for the first direct-acting antiviral agents (DAAs). More recently, in 2013, more effective DAAs, with pan-genomic properties, have been introduced, and these regimens boast increasing rates of SVR. The ultimate goal is that the history of HCV ends with the pan-genotypic efficacy of multiple, easy-to-use and tolerate, combination regimens. These regimens have already demonstrated the ability to cure previously challenging patient groups. However, limitations exist in the current portfolio of agents, with suboptimal outcomes for patients with HCV genotype 3. In addition to this, access to DAAs remains an obstacle for many patients. We present this case of a 61-year-old male with HCV genotype 3 who has had several treatment failures with standard HCV therapy who was eventually approved for compassionate use of a 16-week course of glecaprevir (GLE)/pibrentasvir (PIB), sofosbuvir (SOF), and ribavirin (RBV) which ultimately led to SVR-12.

RESUMO

Breast cancer is the most commonly diagnosed nonskin cancer in women. To decrease the breast cancer burden, conserve resources, and decrease unnecessary treatments, guidelines suggest interventions be reserved for those women at greatest risk for disease. Risk assessment incorporating breast cancer risk factors and risk assessment models is of paramount importance in identifying women who have the greatest benefit from risk reduction strategies. Principles of shared decision-making should guide practitioners to incorporate patients' values, goals, and objectives in decisions around genetic testing, pharmacologic intervention, enhanced surveillance, and other risk reduction strategies.

RESUMO

BACKGROUND AND AIM: The third leading preventable cause of death in the United States is excessive alcohol consumption. Our study sought to assess the impact of the coronavirus disease 2019 (COVID-19) on hospitalizations for alcohol-related hepatitis at a community hospital system. We hypothesized an increase in cases of alcohol-related hepatitis requiring inpatient management, mirroring the strain on economic and societal norms imposed by the COVID-19 pandemic. APPROACH/RESULTS: We performed a retrospective chart review to study the incidence of alcohol-related hepatitis in patients presenting to 3 community hospitals in Fresno, California, before and during the COVID-19. Data including patient demographics, markers of disease severity, and clinical course were extracted from electronic medical records for 329 patients included in the study. There was a 51% increase in the overall incidence of alcohol-related hepatitis requiring hospitalization between 2019 and 2020 (P=0.003) and 69% increase (P<0.001) after implementation of the stay-at-home orders. In addition, 94% (P=0.028) increase in rehospitalizations was noted in 2020 (P=0.028), a 100% increase in patients under the age of 40 (P=0.0028), as well as a trend towards a 125% increase (P=0.06) of female patients admitted with this diagnosis during the COVID-19 pandemic. CONCLUSIONS: Our study revealed drastic increases in severe alcohol-related hepatitis requiring inpatient management, specifically in patients under the age of 40 and in women during the COVID-19 pandemic. Given the high morbidity and mortality associated with severe alcohol-related hepatitis, these findings have far-reaching and lasting implications for our already strained health care system extending beyond the COVID-19 pandemic timeframe. Urgent public health interventions are needed to combat the rising misuse of alcohol and its consequences.

RESUMO

Although a large cohort of potential biomarkers for thyroid cancer aggressiveness have been tested in various formats in recent years, to the best of our knowledge, thyroglobulin and calcitonin remain the only two established biomarkers associated with thyroid cancer management. Our group has recently validated a novel means of maintaining live, human ex vivo thyroid tissue within a tissue-on-chip format. The present pilot study aimed to interrogate the tissue effluent, containing all the soluble markers released by the tissue samples maintained within the devices' tissue chamber, for the presence of markers potentially associated with thyroid cancer aggressiveness. Culture effluent from tissue samples harvested from 19 individual patients who had undergone thyroidectomy for the treatment of suspected thyroid cancer was assessed, first using a proteome profiler™ angiogenesis array kit. Patients were subcategorised as 'aggressive' if they possessed a minimum of N1b level metastases, whilst 'non-aggressive' samples were T3 or lower without evidence of multifocality; and contralateral healthy thyroid tissue was harvested for comparative studies. Levels of Serpin-F1, vascular endothelial growth factor, Thrombospondin-1 and chemokine (C-C motif) ligand were significantly altered and, thus, were further investigated using ELISA to allow for quantitative analysis. The concentration of serpin-F1 was significantly increased in the effluent of aggressive thyroid cancer tissue when compared with levels released by both non-aggressive and benign samples. The present study demonstrated the usability of microfluidic technology for the analysis of the ex vivo tissue secretome in order to identify novel biomarkers.

RESUMO

Hepatic encephalopathy (HE) is a reversible brain dysfunction caused by liver insufficiency and portosystemic shunting. Hepatic encephalopathy is a common complication of advanced liver disease and is on a rise with the increasing incidence of non-alcoholic steatohepatitis (NASH). Since partnership with nursing staff is a critical part of successful management of these complex patients, we conducted a survey assessing their knowledge regarding HE.169 nurses participated in the survey. We found that more than 30% of the nurses did not know that ammonia is one of the toxins responsible for causing hepatic encephalopathy. We also found that 20% of the nurses had difficulty answering questions regarding titration of lactulose to bowel movements. Dietary education is a significant area for improvement as 80% of the nurses wanted to restrict fat and carbohydrate intake in these patients. With this simple survey, we identified important knowledge gaps among experienced nurses at our institution. We believe that by improving knowledge through focused lectures, we can improve patient care and reduce the length of hospitalizations in patients with HE.

RESUMO

Thyroid cancer incidence and related mortality is increasing year-on-year, and although treatment for early disease with surgery and radioiodine results in a 98% 5-year survival rate, recurrence and treatment refractory disease is evident in an unacceptable number of patients. Alternative treatment regimens have therefore been sought in the form of tyrosine kinase inhibitors, immunotherapy, vaccines, chimeric antigen receptor T-cell therapy and oncolytic viruses. The current review aims to consolidate knowledge and highlight the latest clinical trials using secondary therapies in thyroid cancer treatment, focusing on both in vitro and in vivo studies, which have investigated therapies other than radioiodine.

RESUMO

BACKGROUND: Underserved subgroups are less likely to have optimal health prior to pregnancy. We describe preconception health indicators (behavior, pregnancy intention, and obesity) among pregnant Latina women with and without chronic stress in metro Atlanta. DESIGN: We surveyed 110 pregnant Latina women enrolled in prenatal care at three clinics in Atlanta. The survey assessed chronic stress, pregnancy intention, preconception behavior changes (taking folic acid or prenatal vitamins, seeking healthcare advice, any reduction in smoking or drinking), and previous trauma. RESULTS: Specific behaviors to improve health prior to pregnancy were uncommon (e.g., taking vitamins (25.5%) or improving nutrition (20.9%)). Just under half of women were experiencing a chronic stressor at the time of conception (49.5%). Chronically stressed women were more likely to be obese (aOR: 3.0 (1.2, 7.4)), less likely to intend their pregnancy (aOR: 0.3 (0.1, 0.7)), and possibly less likely to report any PHB (45.5% vs. 57.4%; aOR: 0.5 (0.2-1.1)). CONCLUSIONS: Chronically stress women were less likely to enter prenatal care with optimal health. However, preconception behaviors were uncommon overall.

RESUMO

Breastfeeding provides a range of benefits for the infant's growth, immunity, and development. It also has health benefits for the mother, including a reduced risk of premenopausal breast cancer, earlier return to prepregnancy weight, reduction of postpartum bleeding, and reduced risk of osteoporosis. There are a number of complex factors that influence the decision to initiate and continue breastfeeding, including those "external" to women, such as cultural beliefs. The cultural context and environment of decision making are illuminated through the prism of traditions and historical and cultural events. The ideology and sentiment of breastfeeding have changed during the course of history and have evolved within the African American community. Throughout the evolution of infant feeding practices, historical aftermaths have contributed to the legacy and emotional context of infant feeding trends. The tradition of wet nursing for African American women is inherently linked to white supremacy, slavery, medical racism and the physical, emotional, and mental abuse that enslaved African American women endured. Thus, the decision to breastfeed and the act of breastfeeding may remain deeply affected by the generational trauma of wet nursing during slavery. The associated negative connotation of wet nursing, slavery, and medical exploitation is one of the many nuanced cultural barriers that denies Black women and infants the many health benefits of breastfeeding.

RESUMO

Background Postpartum hemorrhage (PPH) is a leading cause of preventable maternal morbidity and mortality. Standardized response to obstetric hemorrhage is associated with significant improvement in maternal outcomes, yet implementation can be challenging. Objective The primary objective is to describe the methodology for program implementation of the Alliance for Innovation on Maternal Health Safety Bundle on PPH at an urban safety-net hospital. Methods Over an 18-month period, interventions geared toward (1) risk assessment and stratification, (2) hemorrhage identification and management, (3) team communication and simulation, and (4) debriefs and case review were implemented. Hemorrhage risk assessment stratification rates were tracked overtime as an early measure of bundle compliance. Results Hemorrhage risk assessment stratification rates improved to >90% during bundle implementation. Conclusion Keys to implementation included multidisciplinary stakeholder commitment, stepwise and iterative approach, and parallel systems for monitoring and evaluation Implementation of a PPH safety bundle is feasible in a resource-constrained setting.
