Access disparities and underutilization of germline genetic testing in Chilean breast cancer patients.

PURPOSE: Latin American reports on genetic cancer risk assessments are scarce. In Chile, current breast cancer (BC) guidelines do not define strategies for germline genetic testing. Our study sought to quantify the disparities in access to genetic testing in Chilean BC patients, according to international standards and their clinical characteristics to explore improvement strategies. METHODS: Retrospective analysis of invasive BC databases including patients treated in a Public Hospital (PH) and in an Academic Private Center (AC) in Santiago, Chile between 2012 and 2021. RESULTS: Of 5438 BC patients, 3955 had enough data for National Comprehensive Cancer Network (NCCN) categorization. From these, 1911 (48.3%) fulfilled NCCN criteria for germline testing, of whom, 300 were tested for germline mutations and 268 with multigene panels. A total of 65 pathogenic variants were found in this subset. As expected, BRCA1/2 mutations were the most frequent (17.7%). Access to genetic testing was higher in AC versus PH (19.6% vs. 10.3%, p = 0.0001). Other variables associated with germline genetic testing were BC diagnosis after 2018, being 45 years old or younger at diagnosis, BC family history (FH), FH of ovarian cancer, non-metastatic disease, and triple-negative subtype. CONCLUSION: In our cohort, 15% of BC patients who met NCCN criteria for germline testing were effectively tested. This percentage was even lower at the PH. Current recommendations encourage universal genetic testing for BC patients; however, our findings suggest that Chile is far from reaching such a goal and national guidelines in this regard are urgently needed. To our knowledge, this is the first study of its kind in Chile and Latin America.

Clinical characteristics, risk factors, and outcomes in Chilean triple negative breast cancer patients: a real-world study.

BACKGROUND: Latin American (LA) studies on triple-negative breast cancer (TNBC) and their characteristics are scarce. This forces physicians to make clinical decisions based on data obtained from studies that include non-Hispanic patients. Our study sought to obtain local epidemiological data, including risk factors and clinical outcomes from a Chilean BC registry. METHODS: This was a retrospective population-cohort study that included patients treated at a community hospital (mid-low income) or an academic private center (high income), in the 2010-2021 period. Univariate and multivariate analyses were performed to identify prognostic factors associated with survival. RESULTS: 647 out of 5,806 BC patients (11.1%) were TNBC. These patients were younger (p = 0.0001) and displayed lower rates of screening-detected cases (p = 0.0001) compared to non-TNBC counterparts. Among TNBC patients, lower income (i. e., receiving treatment at a community hospital) was associated with poorer overall survival (HR: 1.53; p = 0.0001) and poorer BC specific survival (HR: 1.29; p = 0.004). Other risk factors showed no significant differences between TNBC and non-TNBC. As expected, 5-year OS was significantly shorter on TNBC versus non-TNBC patients (p = 0.00001). In our multivariate analyses TNBC subtype (HR: 2.30), locally advanced stage (HR: 7.04 for stage III), lower income (HR: 1.64), or non-screening detected BC (HR: 1.32) were associated with poorer OS. CONCLUSION: To the best of our knowledge, this is the largest LA cohort of TNBC patients. Interestingly, the proportion of TNBC among Chileans was smaller compared to similar studies within LA. As expected, TNBC patients had poorer survival and higher risk for early recurrence versus non-TNBC. Other relevant findings include a higher proportion of premenopausal patients among TNBC. Also, mid/low-income patients that received medical attention at a community hospital displayed lower survival versus private health center counterparts.

Long-term Mammography Utilization after an Initial Randomized Intervention Period by all Underserved Chilean Women in the Clinics.

Chile has one of the highest rates of breast cancer in Latin America. Mammography rates among women, especially those of low socioeconomic status (SES), are thought to contribute to high breast cancer morbidity and mortality. A successful randomized controlled trial among women aged 50 to 70 in a low-SES primary care clinic in Chile led to a significant increase in mammography screening rates in a two-year intervention trial. This study assesses the sustainability of the intervention after ten years and identifies factors that might have been associated with a long-term effect using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. The mammography rates among women aged 50 to 70 in the low-SES intervention clinic were compared to two populations of women aged 50 to 70 from middle-SES clinics and to national data. Qualitative data were used to answer questions of adoption, implementation, and maintenance, while quantitative data assessed the reach and effectiveness. After ten years, low-SES women at the intervention clinic maintained significantly higher mammography screening rates vs. middle-SES women at the comparison clinics (36.2% vs. 30.1% and 19.4% p < 0.0001). Women of a low SES at the intervention clinic also had significantly higher screening rates compared to women of a low SES at a national level (44.2% vs. 34.2% p < 0.0001). RE-AIM factors contributed to understanding the long-term difference in rates. Mailed contact, outreach interventions, and the integration of health promoters as part of the Community Advisory Board were important factors associated with the effects observed. This study provides information on factors that could contribute to reducing the social gap on breast cancer screening.

New beginnings in post graduate medical education. Latin American Medical Education Leaders Forum / Nuevos comienzos en la educación médica de postgrado. Foro Latinoamericano de Líderes en Educación Médica

Introduction: The consequences of the Covid-19 epidemic have been catastrophic for Latin America in 2021. This study explores experiences, lessons learned, and practice changes during this critical time in post-graduate medical education in Latin America. Me-thods: A panel of 53 post-graduate medical education leaders from 8 Latin American countries and Canada was invited to participate in the 2021 Latin American Medical Education Leaders Forum to share their experiences, lessons learned, and main educational practice changes given the Covid-19 pandemic scenario. Participants were selected following a snowball technique with the goal of obtaining a diverse group of experts. Small group discussions were conducted by bilingual facilitators based on a semi-structured questionnaire. The plenary session with the main conclusions of each group was recorded and fully transcribed for a thematic analysis using a framework methods approach. Results: Participants ́ profiles included 13 experienced clinician-educators, 19 program directors, and 23 deans or organizational representatives. Seven specific themes emerged. They followed a pattern that went from an initial emotional reaction of surprise to a complex collective response. The responses highlighted the value of adaptability, the application of new digital skills, a renovated residents' protagonism, the strengthening of humanism in medicine, the openness of new perspectives in wellness, and finally, an unresolved challenge of assessment in medical education in a virtual post-pandemic scenario. Conclusion: A diverse panel of medical educators from Latin America and Canada identified changes triggered by the Covid-19 pandemic that could transform postgraduate medical education in the region.

Screen-detected breast cancer is associated with better prognosis and survival compared to self-detected/symptomatic cases in a Chilean cohort of female patients.

PURPOSE: The implementation of national breast cancer (BC) screening programs in Latin America has been rather inconsistent. Instead, most countries have opted for "opportunistic" mammogram screenings on the population at risk. Our study assessed and compared epidemiological, clinical factors, and survival rates associated with BC detected by screening (SDBC) or self-detected/symptomatic (non-SDBC) in Chilean female patients. METHODS: Registry-based cohort study that included non-metastatic BC (stage I/II/III) patients diagnosed between 1993 and 2020, from a public hospital (PH) and a private university cancer center (PC). Epidemiological and clinical data were obtained from medical records. RESULTS: A total of 4559 patients were included. Most patients (55%; n = 2507) came from PH and were diagnosed by signs/symptoms (non-SDBC; n = 3132, 68.6%); these patients displayed poorer overall (OS) and invasive disease-free survival (iDFS) compared to SDBC. Importantly, the proportion of stage I and "luminal" BC (HR + /HER2 -) were significantly higher in SDBC vs. non-SDBC. Finally, using a stage/subset-stratified age/insurance-adjusted model, we found that non-SDBC cases are at a higher risk of death (HR:1.75; p < 0.001). In contrast, patients with PC health insurance have a lower risk of death (HR: 0.60; p < 0.001). CONCLUSION: We confirm previous studies that report better prognosis/survival on SDBC patients. This is probably due to a higher proportion of stage I and luminal-A cases versus non-SDBC. In turn, the survival benefit observed in patients with PC health insurance might be attributed to a larger proportion of SDBC. Our data support the implementation of a systematic BC screening program in Chile to improve patient prognosis and survival rates.

The interdisciplinary and psychosocial gap in cancer survivorship: A longitudinal study in a Latin American Cancer Center.

BACKGROUND AND OBJECTIVES: There is lack of information on the quality of care provided to the rapidly increasing population of cancer survivors in Latin America. Our study attempts to address this gap and to identify areas needed to be improved. METHODS: A random sample of 210 breast and colorectal cancer survivors were selected from a hospital-based registry in Chile. Cancer registry information, electronic chart review, and personal interviews were used to assess medical and nonmedical care over a 5-year period. Survivorship care practices were compared to a standardized reference based on the US Institute of Medicine domains and the American Cancer Association guidelines. RESULTS: Over 80% of breast and colorectal cancer survivors received appropriate medical care, ongoing testing surveillance and risk factors assessment. Only a third of survivors were assessed for psychosocial disorders and 25% of them received interdisciplinary care. Overall, 66.1% of breast and 58.6% of colorectal cancer survivors reached the expected quality level of cancer survivorship care according to the reference standard (p < .001). CONCLUSION: Medical care practices reached a high standard in a leading cancer center in Latin America. However, a much stronger psychosocial assessment and interdisciplinary care is needed to improve survivorship cancer quality care.

Clinical and serological profile of asymptomatic and non-severe symptomatic COVID-19 cases: Lessons from a longitudinal study in primary care in Latin America.

BACKGROUND: Chile has one of the highest incidences of COVID-19 infection in the world. Primary care can play a key role in early detection and containment of the disease. There is a lack of information on the clinical profile of patients with suspected COVID-19 in primary care, and controversy on the effectiveness of rapid serologic tests in the diagnosis and surveillance of the disease. AIM: To assess the effectiveness of rapid serologic testing in detection and surveillance of COVID-19 cases in primary care. DESIGN & SETTING: A longitudinal study was undertaken, which was based on a non-random sample of 522 participants, including 304 symptomatic patients and 218 high-risk asymptomatic individuals. They were receiving care at four primary health clinics in an underserved area in Santiago, Chile. METHOD: The participants were systematically assessed and tested for COVID-19 with reverse transcriptase-polymerase chain reaction (RT-PCR) and serology at baseline, and were followed clinically and serologically for 3 weeks. RESULTS: The prevalence rate of RT-PCR confirmed COVID-19 cases were 3.5 times higher in symptomatic patients (27.5%; 95% confidence interval [CI] = 22.1 to 32.8) compared with asymptomatic participants (7.9%; 95% CI = 4.3 to 11.6). Similarly, the immune response was significantly different between both groups. Sensitivity of serologic testing was 57.8% (95% CI = 44.8 to 70.1) during the third week of follow-up and specificity was 98.4% (95% CI = 95.5 to 99.7). CONCLUSION: Rapid serologic testing is ineffective for detecting asymptomatic or non-severe cases of COVID-19 at early stages of the disease, but can be of value for surveillance of immunity response in primary care. The clinical profile and immune response of patients with COVID-19 in primary care differs from those in hospital-based populations.

Academic excellence in Latin America: Social accountability of medical schools.

Context: Social accountability of medical schools has emerged as a standard of excellence in medical education during the last decade. However, the lack of valid and reliable instruments to estimate social accountability has limited the possibility of measuring the impact that medical schools have in society. Our aim was to develop an instrument and validate its use for assessing social accountability in Latin American countries.Methods: We used a three-phase mixed methods research design to develop, validate and estimate social accountability in a diverse convenient sample of 49 medical schools from 16 Latin American countries. We used a qualitative framework approach and a Delphi consensus method to design an instrument with high content validity. Finally, we assessed the psychometric properties of the instrument.Results: The Social Accountability Instrument for Latin America (SAIL) contained 21 items in four domains: mission and quality improvement, public policy, community engagement, and professional integrity. Its reliability index, estimated using Cronbach's alpha, was very high (0.96). Most of the medical schools that had ranked over the 80th percentile on traditional national academic estimates did not reach the 80th percentile using SAIL.Conclusions: There are validity arguments (content and reliability) to support the measurement of social accountability using the SAIL instrument. Its application showed that it provides a complementary dimension to that traditionally obtained when estimating quality in medical schools.

Copy number variants in lipid metabolism genes are associated with gallstones disease in men.

Gallstones Disease (GSD) is one of the most common digestive diseases requiring hospitalization and surgical procedures in the world. GSD has a high prevalence in populations with European or Amerindian ancestry (10-20%) and the influence of genetic factors is broadly acknowledged. However, known genetic variants do not entirely explain the disease heritability suggesting that additional genetic variants remain to be identified. Here, we examined the association of copy number variants (CNVs) with GSD in a sample of 4778 individuals (1929 GSD cases and 2849 controls) including two European cohorts from Germany (n = 3702) and one admixed Latin American cohort from Chile (n = 1076). We detected 2936 large and rare CNVs events (size > 100 kb, frequency < 1%). Case-control burden analysis and generalized linear regression models revealed significant association of CNVs with GSD in men, with the strongest effect observed with CNVs overlapping lipid metabolism genes (p-value = 6.54 × 10-4; OR = 2.76; CI 95% = 1.53-4.89). Our results indicate a clear link between CNVs and GSD in men and provides additional evidence that the genetic components of risk for GSD are complex, can be sex specific and include CNVs affecting genes involved in lipid metabolism.

[Burnout in students of health-care professions. Risk and protection factors]. / Burnout en la formación de profesionales de la salud en Chile: Factores de protección y riesgo, y propuestas de abordaje desde la perspectiva de los educadores.

BACKGROUND: The burnout syndrome affects more than half of students and professionals involved in healthcare worldwide and is characterized by emotional exhaustion, depersonalization and a low perception of self-efficacy. Several studies indicate that when students are burnt-out, clinical work, professionalism and ethical behavior, as well as empathy, are negatively affected, while the risk of academic attrition, depression and suicidal ideation tend to increase. At a national level, recent information shows that one out of every two medical students suffer burnout at the beginning of the clinical cycle, a situation that does not improve after finishing undergraduate medical training. There is no consensus on which are the most appropriate strategies to face the problem of burnout in students and health-care professionals. Some studies indicate that the experience of medical and health educators may be key to the design of effective strategies to address this problem. AIM: To identify the burnout risk and protection factors of students at different medical schools. MATERIAL AND METHODS: In this study -in which 34 expert health educators from eight Chilean medical schools and other health-related schools participated- we used a qualitative methodology based on the appreciative inquiry to explore the key elements associated with the occurrence of burnout, identify protective and risk factors, as well as discuss possible effective interventions to prevent it. RESULTS: There are personal, academic and contextual elements that act as protective or risk factors of burnout. In addition, the educators identified key elements to design organizational and curricular interventions to face the problem of burnout at a local level. CONCLUSIONS: Burnout is a serious problem in the formation of health care professionals. Teacher training aimed at promoting student'well-being must include the teaching of communication skills that consider both the generation gap and the profile of the professional medical schools intend to form.

Whole Genome Sequence, Variant Discovery and Annotation in Mapuche-Huilliche Native South Americans.

Whole human genome sequencing initiatives help us understand population history and the basis of genetic diseases. Current data mostly focuses on Old World populations, and the information of the genomic structure of Native Americans, especially those from the Southern Cone is scant. Here we present annotation and variant discovery from high-quality complete genome sequences of a cohort of 11 Mapuche-Huilliche individuals (HUI) from Southern Chile. We found approximately 3.1 × 106 single nucleotide variants (SNVs) per individual and identified 403,383 (6.9%) of novel SNVs events. Analyses of large-scale genomic events detected 680 copy number variants (CNVs) and 4,514 structural variants (SVs), including 398 and 1,910 novel events, respectively. Global ancestry composition of HUI genomes revealed that the cohort represents a sample from a marginally admixed population from the Southern Cone, whose main genetic component derives from Native American ancestors. Additionally, we found that HUI genomes contain variants in genes associated with 5 of the 6 leading causes of noncommunicable diseases in Chile, which may have an impact on the risk of prevalent diseases in Chilean and Amerindian populations. Our data represents a useful resource that can contribute to population-based studies and for the design of early diagnostics or prevention tools for Native and admixed Latin American populations.

Variants in ABCG8 and TRAF3 genes confer risk for gallstone disease in admixed Latinos with Mapuche Native American ancestry.

Latin Americans and Chilean Amerindians have the highest prevalence of gallstone disease (GSD) and gallbladder cancer (GBC) in the world. A handful of loci have been associated with GSD in populations of predominantly European ancestry, however, they only explain a small portion of the genetic component of the disease. Here, we performed a genome-wide association study (GWAS) for GSD in 1,095 admixed Chilean Latinos with Mapuche Native American ancestry. Disease status was assessed by cholecystectomy or abdominal ultrasonography. Top-10 candidate variants surpassing the suggestive cutoff of P < 1 × 10-5 in the discovery cohort were genotyped in an independent replication sample composed of 1,643 individuals. Variants with positive replication were further examined in two European GSD populations and a Chilean GBC cohort. We consistently replicated the association of ABCG8 gene with GSD (rs11887534, P = 3.24 × 10-8, OR = 1.74) and identified TRAF3 (rs12882491, P = 1.11 × 10-7, OR = 1.40) as a novel candidate gene for the disease in admixed Chilean Latinos. ABCG8 and TRAF3 variants also conferred risk to GBC. Gene expression analyses indicated that TRAF3 was significantly decreased in gallbladder (P = 0.015) and duodenal mucosa (P = 0.001) of GSD individuals compared to healthy controls, where according to GTEx data in the small intestine, the presence of the risk allele contributes to the observed effect. We conclude that ABCG8 and TRAF3 genes are associated with GSD and GBC in admixed Latinos and that decreased TRAF3 levels could enhance gallbladder inflammation as is observed in GSD and GSD-associated GBC.

Preferences of Underserved Chilean Women on a Mobile Technology Intervention for Cervical Cancer Screening: Qualitative Study.

BACKGROUND: In Chile and Latin America, cervical cancer disproportionately affects women of low socioeconomic status. Mobile technology (mobile health, mHealth) may be able to address this disparity by targeting women in underserved populations. However, there is a lack of information regarding barriers to the implementation of mHealth interventions in underserved populations. OBJECTIVE: The objective of this study was to investigate the use of cell phones and text messaging (short message service, SMS) in Latina women from disadvantaged communities to design an mHealth intervention for improving cervical cancer screening rates. METHODS: We conducted 9 focus groups among women aged 25-64 years to better understand the implementation barriers and perceptions of a text message (SMS)-based intervention designed to improve cervical cancer screening rates. We used the PRECEDE-PROCEED model to categorize identified themes using template analysis. RESULTS: Focus group results indicated that older women use mobile phones to receive calls from family and friends but seldom send text messages. Furthermore, they prefer personal contact with their health care providers regarding Papanicolaou (Pap) testing. Younger women, on the other hand, find text messaging easy to use and frequently send texts to family and friends. Importantly, women of all ages mentioned they would like to receive text messages about Pap tests. Factors that facilitate the uptake of the intervention include ease of access to Pap testing, inclusion of family members, and reminder messaging. Potential barriers include cost and the impersonal nature of messaging. Health team members support an mHealth intervention even though they acknowledge the potential barriers to this strategy. Overall, these results support the implementation of an mHealth intervention to increase cervical cancer screening rates. CONCLUSIONS: This study describes the opinions of women nonadherent to Pap testing on the potential use of mobile technologies for cervical cancer screening. Although the overall acceptance was positive, older women prefer personal contact and phone calls over text messaging. Information surrounding these preferences will aid in the implementation of effective strategies to improve cancer screening in underserved populations.

Development of mobile technologies for the prevention of cervical cancer in Santiago, Chile study protocol: a randomized controlled trial.

BACKGROUND: In Chile, more than 500 women die every year from cervical cancer, and a majority of Chilean women are not up-to-date with their Papanicolau (Pap) test. Mobile health has great potential in many health areas, particularly in health promotion and prevention. There are no randomized controlled trials in Latin America assessing its use in cervical cancer screening. The 'Development of Mobile Technologies for the Prevention of Cervical Cancer in Santiago, Chile' study aims to determine the efficacy of a text-message intervention on Pap test adherence among Chilean women in the metropolitan region of Santiago. METHODS/DESIGN: This study is a parallel randomized-controlled trial of 400 Chilean women aged 25-64 who are non-adherent with current recommendations for Pap test screening. Participants will be randomly assigned to (1) a control arm (usual care) or (2) an intervention arm, where text and voice messages containing information and encouragement to undergo screening will be sent to the women. The primary endpoint is completion of a Pap test within 6 months of baseline assessment, as determined by medical record review at community-based clinics. Medical record reviewers will be blinded to randomization arms. The secondary endpoint is an evaluation of the implementation and usability of the text message intervention as a strategy to improve screening adherence. DISCUSSION: This intervention using mobile technology intends to raise cervical cancer screening adherence and compliance among a Chilean population of low and middle-low socioeconomic status. If successful, this strategy may reduce the incidence of cervical cancer. TRIAL REGISTRATION: Clinicaltrials.gov NCT02376023 Registered 2/17/2015. First participant enrolled Feb 22nd 2016.

"In our own words": Defining medical professionalism from a Latin American perspective.

BACKGROUND: Latin America has experienced a tremendous growth in a number of medical schools, and there are concerns about their quality of training in critical areas such as professionalism. Medical professionalism is a cultural construct. The aim of the study was to compare published definitions of medical professionalism from Latin American and non-Latin American regions and to design an original and culturally sound definition. METHODS: A mixed methods approach was used with three phases. First, a systematic search and thematic analysis of the literature were conducted. Second, a Delphi methodology was used to design a local definition of medical professionalism. Third, we used a qualitative approach that combined focus groups and personal interviews with students and deans from four medical schools in Chile to understand various aspects of professionalism education. The data were analyzed using NVivo software. RESULTS: A total of 115 nonrepeated articles were identified in the three databases searched. No original definitions of medical professionalism from Latin America were found. Twenty-six articles met at least one of the three decisional criteria defined and were fully reviewed. Three theoretical perspectives were identified: contractualism, personalism, and deontology. Attributes of medical professionalism were classified in five dimensions: personal, interpersonal, societal, formative, and practical. Participants of the Delphi panel, focus groups, and personal interviews included 36 medical students, 12 faculties, and four deans. They took a personalistic approach to design an original definition of medical professionalism and highlighted the relevance of respecting life, human dignity, and the virtue of prudence in medical practice. Students and scholars differed on the value given to empathy and compassion. DISCUSSION: This study provides an original and culturally sound definition of medical professionalism that could be useful in Latin American medical schools. The methodology used in the study could be applied in other regions as a basis to develop culturally appropriate definitions of medical professionalism.

Caregiver's depressive symptoms and asthma control in children from an underserved community.

Caregiver's or maternal depression has been associated with increased asthma morbidity in children from prosperous nations, but little is known about this link in low and middle-income countries. OBJECTIVE: To examine if caregiver's depressive symptoms are associated with poor asthma control and abnormal immune responses in school-aged children. METHODS: Case-control study of 87 asthmatic children (aged 4-11 years) attending a primary care clinic in an underserved area of Santiago (Chile). Cases were children with poor asthma control (Child Asthma Control Test [cACT] <20 points) and controls were children with adequate asthma control (cACT ≥20 points). The Beck Depression Inventory-II (BDI) and a locally validated family health vulnerability test (SALUFAM) were used to assess caregivers' depression and family health vulnerability. Serum from participating children was assayed for IFN-γ, IL-4, IL-13, TGF-ß, cortisol, and total IgE. RESULTS: The mean (SD) age of study participants was 8.23 (2.15 years), and 55.2% were females. Use of inhaled corticosteroids (ICS), family health vulnerability, and caregiver's depressive symptoms were significantly more common in cases than in controls (65.4% vs. 34.6%, p = 0.003; 41.3% vs. 24.8%, p = 0.07; and 39.1% vs. 19.5%, p = 0.04, respectively). There was no significant difference in the level of any serum biomarkers between groups. In a multivariate analysis, only ICS use was significantly associated with better asthma control (OR = 3.56 [1.34-9.48], p = 0.01). CONCLUSIONS: Presence of caregiver's depressive symptoms is associated with poor asthma control among children from an underserved community, but this association was no longer significant after accounting for ICS use.
