Experiences of Advanced Breast Cancer Among Latina Immigrants: A Qualitative Pilot Study.

To explore the experiences of Latina immigrants with advanced breast cancer and their support networks. We conducted semi-structured interviews with low-income Latina immigrants with advanced breast cancer and their support networks (informal caregivers, physicians, and complementary medicine (CM) practitioners). Patient interviews explored patients' illness experience and end of life (EOL) concerns. Support network member interviews focused on the relationship of the interviewee with the patient and EOL conversations. Six authors independently coded transcripts and jointly conducted qualitative thematic analysis. 72 total interviews (13 patients, 12 informal caregivers, 6 CM practitioners, and 4 physicians) revealed two themes. (1) Staying positive was a primary patient coping mechanism. (2) Patients' language barriers and socioeconomic and immigration status posed challenges in participants' illness experience. Appropriately addressing language barriers and social context during medical visits is crucial for effective EOL care. Clinicians should consider patients' financial constraints and ensure support in applying for public benefits.

Interventions to Improve Patient Comprehension in Informed Consent for Medical and Surgical Procedures: An Updated Systematic Review.

Background. Patient comprehension is fundamental to valid informed consent. Current practices often result in inadequate patient comprehension. Purpose. An updated review to evaluate the characteristics and outcomes of interventions to improve patient comprehension in clinical informed consent. Data Sources. Systematic searches of MEDLINE and EMBASE (2008-2018). Study Selection. We included randomized and nonrandomized controlled trials evaluating interventions to improve patient comprehension in clinical informed consent. Data Extraction. Reviewers independently abstracted data using a standardized form, comparing all results and resolving disagreements by consensus. Data Synthesis. Fifty-two studies of 60 interventions met inclusion criteria. Compared with standard informed consent, a statistically significant improvement in patient comprehension was seen with 43% (6/14) of written interventions, 56% (15/27) of audiovisual interventions, 67% (2/3) of multicomponent interventions, 85% (11/13) of interactive digital interventions, and 100% (3/3) of verbal discussion with test/feedback or teach-back interventions. Eighty-five percent of studies (44/52) evaluated patients' understanding of risks, 69% (41/52) general knowledge about the procedure, 35% (18/52) understanding of benefits, and 31% (16/52) understanding of alternatives. Participants' education level was reported heterogeneously, and only 8% (4/52) of studies examined effects according to health literacy. Most studies (79%, 41/52) did not specify participants' race/ethnicity. Limitations. Variation in interventions and outcome measures precluded conduct of a meta-analysis or calculation of mean effect size. Control group processes were variable and inconsistently characterized. Nearly half of studies (44%, 23/52) had a high risk of bias for the patient comprehension outcome. Conclusions. Interventions to improve patient comprehension in informed consent are heterogeneous. Interactive interventions, particularly with test/feedback or teach-back components, appear superior. Future research should emphasize all key elements of informed consent and explore effects among vulnerable populations.

End-of-Life Concerns and Experiences of Living With Advanced Breast Cancer Among Medically Underserved Women.

CONTEXT: Breast cancer morbidity and mortality disproportionately affect medically underserved women. Most studies of the experience of living with advanced breast cancer do not focus on this population. A deeper understanding of racial/ethnic minorities' and low-income patients' experiences is needed to reduce breast cancer health and health care disparities. OBJECTIVES: This qualitative, community-based participatory research study explores the lived experiences of medically underserved women with advanced breast cancer. METHODS: We conducted in-depth, semistructured interviews with low-income patients from a community clinic and safety-net hospital, focusing on issues related to advanced breast cancer and end of life. Six team members independently coded transcripts, jointly reconciled coding differences, and identified key themes. RESULTS: All 63 participants (83% response rate) had an income ≤200% of the federal poverty level; 68% identified as a racial/ethnic minority. Four predominant themes emerged: compounding of pre-existing financial distress, perceived bias/lack of confidence in medical care received, balancing personal needs with the needs of others, and enhanced engagement with sources of life meaning. CONCLUSION: Participants resiliently maintained engaged lives yet described extreme financial duress and perceived provider bias, which are known contributors to worse quality of life and health outcomes. Participants downplayed their desire to discuss dying to accommodate pressure to "stay positive" and to mitigate others' discomfort. Improving care for underserved women with advanced cancer will require addressing disparities from screening through hospice, developing personalized opportunities to discuss death and dying, and enhancing access to and affordability of medical and social support.

Medical Students' Perceptions of and Responses to Health Care Disparities During Clinical Clerkships.

PURPOSE: To measure the frequency and nature of student-perceived clinician-driven health care disparities, and determine their impact on medical students' professional development. METHOD: Retrospective study of fourth-year medical students at the University of California, San Francisco School of Medicine, August 2016 to June 2017. Conducted via an electronic survey asking about frequency/nature of directly witnessed health care disparities and barriers/facilitators to action during third-year clerkships; and individual, semistructured interviews focusing on clinical details and impact on students' professional development. RESULTS: Respondents were 103/159 students (65%). In internal medicine clerkships, a majority perceived disparities as occurring sometimes (2-7 times in eight-week clerkship) or often (at least once weekly or nearly daily) based on language barriers (90%), patients' homelessness (77%), history of substance abuse (76%), obesity (67%), and race/ethnicity: Latino (72%), black (71%), and Asian (56%). Results from other clerkships were similar. Barriers to student action to perceived disparities included fear of poor evaluations, hierarchy/powerlessness, a "don't speak up" culture, the desire to be a team player, limited clinical experience, and perceiving doctors as "good people" who provide disparate care unintentionally. Impact on professional development varied, ranging from students' normalization of disparities as stemming from clinical constraints to increased motivation to provide equitable care. CONCLUSIONS: Medical students routinely witness health care disparities during clerkships, and their observations spotlight specific clinical practices. For some students, these observations lead to a normalization of disparities; for others, they heighten commitment to equity. Clinical curricula should incorporate responding to health care disparities.

Functionality of a novel follitropin alfa pen injector: results from human factor interactions by patients and nurses.

OBJECTIVE: The main objective of this user experience testing study was to evaluate the impact of human factors on the use of a disposable pen containing follitropin alfa by patients and nurses with special focus on the convenience, safety and ease of use, in different types of stimulation protocols. METHODS: Infertile women trying to conceive, and specialist nurses were recruited across 6 European countries. In total 18 patients and 19 nurses took part in the testing, which included both nurse-patient pairings and in-depth interviews. A standardized list of expected and pre-defined critical steps according to the Instructions for Use (IFU), was used to assess the correct handling of the pen. RESULTS: During the user experience testing, no critical errors, related to the use of the pen, which could affect the success of the injection process were identified. In general, both nurses and patients found the pen very easy to learn, use and would be confident using the pen for self-injection. Nurses also found the pen very easy to train the patients. CONCLUSIONS: The study provides valuable information on the pen from both patient and nurse perspectives in different simulated scenarios reflecting standard practice.

Granulocyte colony-stimulating factor improves cerebrovascular reserve capacity by enhancing collateral growth in the circle of Willis.

BACKGROUND AND PURPOSE: Restoration of cerebrovascular reserve capacity (CVRC) depends on the recruitment and positive outward remodeling of preexistent collaterals (arteriogenesis). With this study, we provide functional evidence that granulocyte colony-stimulating factor (G-CSF) augments therapeutic arteriogenesis in two animal models of cerebral hypoperfusion. We identified an effective dosing regimen that improved CVRC and stimulated collateral growth, thereby improving the outcome after experimentally induced stroke. METHODS: We used two established animal models of (a) cerebral hypoperfusion (mouse, common carotid artery ligation) and (b) cerebral arteriogenesis (rat, 3-vessel occlusion). Following therapeutic dose determination, both models received either G-CSF, 40 µg/kg every other day, or vehicle for 1 week. Collateral vessel diameters were measured following latex angiography. Cerebrovascular reserve capacities were assessed after acetazolamide stimulation. Mice with left common carotid artery occlusion (CCAO) were additionally subjected to middle cerebral artery occlusion, and stroke volumes were assessed after triphenyltetrazolium chloride staining. Given the vital role of monocytes in arteriogenesis, we assessed (a) the influence of G-CSF on monocyte migration in vitro and (b) monocyte counts in the adventitial tissues of the growing collaterals in vivo. RESULTS: CVRC was impaired in both animal models 1 week after induction of hypoperfusion. While G-CSF, 40 µg/kg every other day, significantly augmented cerebral arteriogenesis in the rat model, 50 or 150 µg/kg every day did not show any noticeable therapeutic impact. G-CSF restored CVRC in mice (5 ± 2 to 12 ± 6%) and rats (3 ± 4 to 19 ± 12%). Vessel diameters changed accordingly: in rats, the diameters of posterior cerebral arteries (ipsilateral: 209 ± 7-271 ± 57 µm; contralateral: 208 ± 11-252 ± 28 µm) and in mice the diameter of anterior cerebral arteries (185 ± 15-222 ± 12 µm) significantly increased in the G-CSF groups compared to controls. Stroke volume in mice (10 ± 2%) was diminished following CCAO (7 ± 4%) and G-CSF treatment (4 ± 2%). G-CSF significantly increased monocyte migration in vitro and perivascular monocyte numbers in vivo. CONCLUSION: G-CSF augments cerebral collateral artery growth, increases CVRC and protects from experimentally induced ischemic stroke. When comparing three different dosing regimens, a relatively low dosage of G-CSF was most effective, indicating that the common side effects of this cytokine might be significantly reduced or possibly even avoided in this indication.

Acetylsalicylic acid, but not clopidogrel, inhibits therapeutically induced cerebral arteriogenesis in the hypoperfused rat brain.

This study investigated the effects of acetylsalicylic acid (ASA) and clopidogrel, standardly used in the secondary prevention of vascular occlusions, on cerebral arteriogenesis in vivo and in vitro. Cerebral hypoperfusion was induced by three-vessel occlusion (3-VO) in rats, which subsequently received vehicle, ASA (6.34 mg/kg), or clopidogrel (10 mg/kg). Granulocyte colony-stimulating factor (G-CSF), which enhanced monocyte migration in an additional cell culture model, augmented cerebrovascular arteriogenesis in subgroups (40 µg/kg). Cerebrovascular reactivity and vessel diameters were assessed at 7 and 21 days. Cerebrovascular reserve capacity was completely abolished after 3-VO and remained severely compromised after 7 (-14±14%) and 21 (-5±11%) days in the ASA groups in comparison with controls (4±5% and 10±10%) and clopidogrel (4±13% and 10±8%). It was still significantly decreased when ASA was combined with G-CSF (1±4%) compared with G-CSF alone (20±8%). Posterior cerebral artery diameters confirmed these data. Monocyte migration into the vessel wall, improved by G-CSF, was significantly reduced by ASA. Acetylsalicylic acid, but not clopidogrel, inhibits therapeutically augmented cerebral arteriogenesis.
