RESUMO

BACKGROUND: Disaggregated data is a cornerstone of precision health. Vietnamese Americans (VietAms) are the fourth-largest Asian subgroup in the United States (US), and demonstrate a unique burden of disease and mortality. However, most prior studies have aggregated VietAms under the broader Asian American category for analytic purposes. This study examined the leading causes of death among VietAms compared to aggregated Asian Americans and non-Hispanic Whites (NHWs) during the period 2005-2020. METHODS: Decedent data, including underlying cause of death, were obtained from the National Center for Health Statistics national mortality file from 2005 to 2020. Population denominator estimates were obtained from the American Community Survey one-year population estimates. Outcome measures included proportional mortality, age-adjusted mortality rates per 100,000 (AMR), and annual percent change (APC) in mortality over time. Data were stratified by sex and nativity status. Due to large differences in age structure, we report native- and foreign-born VietAms separately. FINDINGS: We identified 74,524 VietAm decedents over the study period (71,305 foreign-born, 3,219 native-born). Among foreign-born VietAms, the three leading causes of death were cancer (26.6%), heart disease (18.0%), and cerebrovascular disease (9.0%). Among native-born VietAms the three leading causes were accidents (19.0%), self-harm (12.0%), and cancer (10.4%). For every leading cause of death, VietAms exhibited lower mortality compared to both aggregated Asians and NHWs. Over the course of the study period, VietAms witnessed an increase in mortality in every leading cause. This effect was mostly driven by foreign-born, male VietAms. CONCLUSIONS AND RELEVANCE: While VietAms have lower overall mortality from leading causes of death compared to aggregated Asians and NHWs, these advantages have eroded markedly between 2005 and 2020. These data emphasize the importance of racial disaggregation in the reporting of public health measures.

RESUMO

BACKGROUND: Social determinants of health (SDOH) play a significant role in the development of cardiovascular risk factors. We investigated SDOH associations with cardiovascular risk factors among Asian American subgroups. METHODS AND RESULTS: We utilized the National Health Interview Survey, a nationally representative survey of US adults, years 2013 to 2018. SDOH variables were categorized into economic stability, neighborhood and social cohesion, food security, education, and health care utilization. SDOH score was created by categorizing 27 SDOH variables as 0 (favorable) or 1 (unfavorable). Self-reported cardiovascular risk factors included diabetes, high cholesterol, high blood pressure, obesity, insufficient physical activity, suboptimal sleep, and nicotine exposure. Among 6395 Asian adults aged ≥18 years, 22.1% self-identified as Filipino, 21.6% as Asian Indian, 21.0% as Chinese, and 35.3% as other Asian. From multivariable-adjusted logistic regression models, each SD increment of SDOH score was associated with higher odds of diabetes among Chinese (odds ratio [OR], 1.45; 95% CI, 1.04-2.03) and Filipino (OR, 1.24; 95% CI, 1.02-1.51) adults; high blood pressure among Filipino adults (OR, 1.28; 95% CI, 1.03-1.60); insufficient physical activity among Asian Indian (OR, 1.42; 95% CI, 1.22-1.65), Chinese (OR, 1.58; 95% CI, 1.33-1.88), and Filipino (OR, 1.24; 95% CI, 1.06-1.46) adults; suboptimal sleep among Asian Indian adults (OR, 1.20; 95% CI, 1.01-1.42); and nicotine exposure among Chinese (OR, 1.56; 95% CI, 1.15-2.11) and Filipino (OR, 1.50; 95% CI, 1.14-1.97) adults. CONCLUSIONS: Unfavorable SDOH are associated with higher odds of cardiovascular risk factors in Asian American subgroups. Culturally specific interventions addressing SDOH may help improve cardiovascular health among Asian Americans.

RESUMO

Introduction: Vaccination rates may be improved through culturally tailored messages, but little is known about them among disaggregated Asian American subgroups. We assessed the vaccination rates for key vaccines among these subgroups. Methods: Using the National Health Interview Survey, we analyzed recent vaccination rates (2015-2018, n=188,250) and trends (2006-2018) among Asians (Chinese [n=3,165], Asian Indian [n=3,525], Filipino [n=3,656], other Asian [n=5,819]) and non-Hispanic White adults (n=172,085) for 6 vaccines (the human papillomavirus, hepatitis B, pneumococcal, influenza, tetanus-diphtheria [tetanus], and shingles vaccines). We controlled demographic, socioeconomic, and health-related variables in multivariable logistic regression and predicted marginal modeling analyses. We also computed vaccination rates among Asian American subgroups on the 2015-2018 National Health Interview Survey data stratified by foreign-born and U.S.-born status. We used Joinpoint regression to analyze trends in vaccination rates. All analyses were conducted in 2021 and 2022. Results: Among Asians, shingles (29.2%; 95% CI=26.6, 32.0), tetanus (53.7%; 95% CI=51.8, 55.6), and pneumococcal (53.8%; 95% CI=50.1, 57.4) vaccination rates were lower than among non-Hispanic Whites. Influenza (47.9%; 95% CI=46.2, 49.6) and hepatitis B (40.5%; 95% CI=39.0, 42.7) vaccination rates were similar or higher than among non-Hispanic Whites (48.4%; 95% CI=47.9, 48.9 and 30.7%; 95% CI=30.1, 31.3, respectively). Among Asians, we found substantial variations in vaccination rates and trends. For example, Asian Indian women had lower human papillomavirus vaccination rates (12.9%; 95% CI=9.1, 18.0) than all other Asian subgroups (Chinese: 37.9%; 95% CI=31.1, 45.2; Filipinos: 38.7%; 95% CI=29.9, 48.3; other Asians: 30.4%; 95% CI=24.8, 36.7) and non-Hispanic Whites (36.1%; 95% CI=34.8, 37.5). Being male, having lower educational attainment and income, having no health insurance or covered by public health insurance only, and lower frequency of doctor visits were generally associated with lower vaccine uptakes. Foreign-born Asian aggregate had lower vaccination rates than U.S.-born Asian aggregate for all vaccines except for influenza. We also found subgroup-level differences in vaccination rates between foreign-born and U.S.-born Asians. We found that (1) foreign-born Chinese, Asian Indians, and other Asians had lower human papillomavirus and hepatitis B vaccination rates; (2) foreign-born Chinese and Filipinos had lower pneumococcal vaccination rates; (3) foreign-born Chinese and Asian Indians had lower influenza vaccination rates; and (4) all foreign-born Asian subgroups had lower tetanus vaccination rates. Conclusions: Vaccination rates and trends differed among Asian American subgroups. Culturally tailored messaging and interventions may improve vaccine uptakes.

RESUMO

Objective: This cross-sectional study aims to better understand the heterogeneous associations of acculturation level on CV risk factors among disaggregated Asian subgroups. We hypothesize that the association between acculturation level and CV risk factors will differ significantly by Asian subgroup. Methods: We used the National Health Interview Survey (NHIS), a nationally representative US survey, years 2014-18. Acculturation was defined using: (a) years in the US, (b) US citizenship status, and (c) level of English proficiency. We created an acculturation index, categorized into low vs. high (scores of 0-3 and 4, respectively). Self-reported CV risk factors included diabetes, high cholesterol, hypertension, obesity, tobacco use, and sufficient physical activity. Rao-Scott Chi Square was used to compare age-standardized, weighted prevalence of CV risk factors between Asian subgroups. We used logistic regression analysis to assess associations between acculturation and CV risk factors, stratified by Asian subgroup. Results: The study sample consisted of 6,051 adults ≥ 18 years of age (53.9% female; mean age 46.6 [SE 0.33]). The distribution by race/ethnicity was Asian Indian 26.9%, Chinese 22.8%, Filipino 18.1%, and other Asian 32.3%. The association between acculturation and CV risk factors differed by Asian subgroups. From multivariable adjusted models, high vs. low acculturation was associated with: high cholesterol amongst Asian Indian (OR=1.57, 95% CI: 1.11, 2.37) and other Asian (OR=1.48, 95% CI: 1.10, 2.01) adults, obesity amongst Filipino adults (OR= 1.62, 95% CI: 1.07, 2.45), and sufficient physical activity amongst Chinese (OR= 1.54, 95% CI: 1.09, 2.19) and Filipino adults (OR=1.58, 95% CI: 1.10, 2.27). Conclusion: This study demonstrates that acculturation is heterogeneously associated with higher prevalence of CV risk factors among Asian subgroups. More studies are needed to better understand these differences that can help to inform targeted, culturally specific interventions.

RESUMO

OBJECTIVE: Asian Indians are among the fastest growing United States (US) ethnic subgroups. We characterized mortality trends for leading causes of death among foreign-born and US-born Asian Indians in the US between 2005-2017. STUDY DESIGN AND SETTING: Using US standardized death certificate data, we examined leading causes of death in 73,470 Asian Indians and 20,496,189 non-Hispanic whites (NHWs) across age, gender, and nativity. For each cause, we report age-standardized mortality rates (AMR), longitudinal trends, and absolute percent change (APC). RESULTS: We found that Asian Indians' leading causes of death were heart disease (28% mortality males; 24% females) and cancer (18% males; 22% females). Foreign-born Asian Indians had higher all-cause AMR compared to US-born (AMR 271 foreign-born, CI 263-280; 175.8 US-born, CI 140-221; p<0.05), while Asian Indian all-cause AMR was lower than that of NHWs (AMR 271 Indian, CI 263-278; 754.4 NHW, CI 753.3-755.5; p<0.05). All-cause AMR increased for foreign-born Asian Indians over time, while decreasing for US-born Asian Indians and NHWs. CONCLUSIONS: Foreign-born Asian Indians were 2.2 times more likely to die of heart disease and 1.6 times more likely to die of cancer. Asian Indian male AMR was 49% greater than female on average, although AMR was consistently lower for Asian Indians when compared to NHWs.

RESUMO

INTRODUCTION: Asian Americans suffer high rates of smoking and tobacco-related deaths, varying by ethnic group. Trends of cigarette and alternative tobacco product use among Asian Americans, specifically considering ethnic group, sex, and nativity, are infrequently reported. METHODS: Using National Health Interview Survey (NHIS) data from 2006-2018 and the 2016-2018 alternative tobacco supplement (e-cigarettes, cigars, smokeless tobacco, pipes), we explored cigarette and alternative tobacco product use by Asian ethnic group (Asian Indian (n = 4373), Chinese (n = 4736), Filipino (n = 4912)) in comparison to non-Hispanic Whites (NHWs (n = 275,025)), adjusting for socioeconomic and demographic factors. RESULTS: Among 289,046 adults, 12% of Filipinos were current smokers, twice the prevalence in Asian Indians and Chinese (p < 0.001). The male-female gender difference was fivefold for Chinese (10.3% vs. 2.2%; p < 0.001), eightfold for Asian Indians (8.7% vs. 1.1%; p < 0.001), and twofold for Filipinos (16.8% vs. 9.0%). Moreover, 16.3% of US-born and 10.3% of foreign-born Filipinos were current smokers. Odds of ever using e-cigarettes, cigars, smokeless tobacco, and pipes in comparison to NHWs were lowest for Chinese (ORs 0.6, 0.5, 0.2, and 0.5). DISCUSSION: Filipinos had the highest current smoking rates of Asian ethnic groups. Though more Asian men were current smokers, the high rate of current smoking among Filipinas is concerning. More US-born Filipinos were current smokers than foreign-born, despite rates typically decreasing for US-born Asians. Investigating cultural factors contributing to less frequent use of tobacco products, such as alternative tobacco products among Chinese, may aid campaigns in curbing tobacco usage.

RESUMO

BACKGROUND: Asian Americans (AA) are the fastest growing ethnic group in the United States with high proportions of immigrants. Nativity is important as cancer risk factors vary by country. We sought to understand differences in cancer mortality among AAs by nativity (foreign-born vs. U.S.-born). METHODS: Ninety-eight thousand eight hundred and twenty-six AA (Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese) decedents with cancer-related deaths from U.S. death certificates (2008-2017) were analyzed. Thirteen cancers that contribute significantly to Asian-American cancer mortality were selected and categorized by etiology: tobacco-related, screen-detected, diet-/obesity-related, and infection-related. Ten-year age-adjusted mortality rates [AAMR; 95% confidence interval (CI); per 100,00] and standardized mortality ratios (SMR; 95% CI) using foreign-born as the reference group were calculated. RESULTS: Overall, foreign-born AAs had higher mortality rates than U.S.-born. Japanese U.S.-born males had the highest tobacco-related mortality rates [foreign-born AAMR: 43.02 (38.72, 47.31); U.S.-born AAMR: 55.38 (53.05, 57.72)]. Screen-detected death rates were higher for foreign-born than U.S.-born, except for among Japanese males [SMR 1.28 (1.21-1.35)]. Diet-/obesity-related AAMRs were higher among females than males and highest among foreign-born females. Foreign-born males and females had higher infection-related AAMRs than U.S.-born; the highest rates were foreign-born males-Korean [AAMR 41.54 (39.54, 43.53)] and Vietnamese [AAMR 41.39 (39.68, 43.09)]. CONCLUSIONS: We observed substantial heterogeneity in mortality rates across AA groups and by nativity. Contrary to the Healthy Immigrant Effect, most foreign-born Asians were dying at higher rates than U.S.-born AAs. IMPACT: Disaggregated analysis of AA cancers, targeted and culturally tailored cancer screening, and treatments for infections among foreign-born Asians is critical for cancer prevention efforts.

RESUMO

BACKGROUND: Narrative Medicine may mitigate physician burnout by increasing empathy and self-compassion, and by encouraging physicians to deeply connect with patient stories/experiences. However, Narrative Medicine has been difficult to implement on hectic inpatient teaching services that are often the most emotionally taxing for residents. OBJECTIVE: To evaluate programmatic and learner outcomes of a novel narrative medicine curriculum implementation during inpatient medicine rotations for medical residents. Programmatic outcomes included implementation lessons. Learner outcomes included preliminary understanding of impact on feelings of burnout. Additionally, we developed a generalizable narrative medicine framework for program implementation across institutions. METHODS: We developed and implemented a monthly 45-min Narrative Medicine workshop on Stanford's busiest and emotionally-demanding inpatient rotation (medical oncology). Using the Physician Wellbeing Inventory (PWBI, range 1-7; 3-4 = high burnout risk; ≥4, high burnout), we anonymously assessed resident burnout during pre-implementation control year (2017-2018, weeks 1 and 4), and implementation year (2018-2019, weeks 1 and 4). We interviewed program directors and facilitators regarding curriculum implementation challenges/facilitators. RESULTS: Residents highly rated the narrative medicine curriculum, and the residency program renewed the course for 3 additional years. We identified success factors for programmatic success including time neutrality, control of session, learning climate, building trust, staff partnership, and facilitators training. During control year, resident burnout was initially high (n = 16; mean PBWI = 3.0, SD: 1.1) and increased by the final week (n = 15; PBWI = 3.4, SD: 1.6). During implementation year, resident burnout was initially similar (n = 13; PBWI = 3.1, SD: 1.9) but did not rise as much by rotation end (n = 24; PBWI = 3.3, SD: 1.6). Implementation was underpowered to detect small effect sizes. Based on our our experience and literature review, we propose an educational competency framework potentially helpful to facilitate inpatient narrative medicine workshops, as a blueprint for other institutions. CONCLUSIONS: Inpatient Narrative Medicine is feasible to implement during a challenging inpatient rotation and may have important short-term effects in mitigating burnout rise, with more study needed. We share teaching tools and propose a competency framework which may be useful to support development of inpatient narrative medicine curricula across institutions.

RESUMO

Asian Americans (AAs) are heterogeneous, and aggregation of diverse AA populations in national reporting may mask high-risk groups. Gastrointestinal (GI) cancers constitute one-third of global cancer mortality, and an improved understanding of GI cancer mortality by disaggregated AA subgroups may inform future primary and secondary prevention strategies. Using national mortality records from the United States from 2003 to 2017, we report age-standardized mortality rates, standardized mortality ratios and annual percent change trends from GI cancers (esophageal, gastric, colorectal, liver and pancreatic) for the six largest AA subgroups (Asian Indians, Chinese, Filipinos, Japanese, Koreans and Vietnamese). Non-Hispanic Whites (NHWs) are used as the reference population. We found that mortality from GI cancers demonstrated nearly 3-fold difference between the highest (Koreans, 61 per 100 000 person-years) and lowest (Asian Indians, 21 per 100 000 person-years) subgroups. The distribution of GI cancer mortality demonstrates high variability between subgroups, with Korean Americans demonstrating high mortality from gastric cancer (16 per 100 000), and Vietnamese Americans demonstrating high mortality from liver cancer (19 per 100 000). Divergent temporal trends emerged, such as increasing liver cancer burden in Vietnamese Americans, which exacerbated existing mortality differences. There exist striking differences in the mortality burden of GI cancers by disaggregated AA subgroups. These data highlight the need for disaggregated data reporting, and the importance of race-specific and personalized strategies of screening and prevention.

RESUMO

Phosphodiesterases (PDE) are a diverse family of enzymes (11 isoforms so far identified) responsible for the degradation of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) which are involved in several cellular and biochemical functions. Phosphodiesterase 4 (PDE4) is the major isoform within this group and is highly expressed in the mammalian brain. An inverse association between PDE4 and cAMP levels is the key mechanism in various pathophysiological conditions like airway inflammatory diseases-chronic obstruction pulmonary disease (COPD), asthma, psoriasis, rheumatoid arthritis, and neurological disorders etc. In 2011, roflumilast, a PDE4 inhibitor (PDE4I) was approved for the treatment of COPD. Subsequently, other PDE4 inhibitors (PDE4Is) like apremilast and crisaborole were approved by the Food and Drug Administration (FDA) for psoriasis, atopic dermatitis etc. Due to the adverse effects like unbearable nausea and vomiting, dose intolerance and diarrhoea, PDE4 inhibitors have very less clinical compliance. Efforts are being made to develop allosteric modulation with high specificity to PDE4 isoforms having better efficacy and lesser adverse effects. Interestingly, repositioning PDE4Is towards neurological disorders including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), multiple sclerosis (MS) and sleep disorders, is gaining attention. This review is an attempt to summarize the data on the effects of PDE4 overexpression in neurological disorders and the use of PDE4Is and newer allosteric modulators as therapeutic options. We have also compiled a list of on-going clinical trials on PDE4 inhibitors in neurological disorders.

RESUMO

Mammalian alpha/beta hydrolase domain (ABHD) family of proteins have emerged as key regulators of lipid metabolism and are found to be associated with human diseases. Human α/ß-hydrolase domain containing protein 11 (ABHD11) has recently been predicted as a potential biomarker for human lung adenocarcinoma. In silico analyses of the ABHD11 protein sequence revealed the presence of a conserved lipase motif GXSXG. However, the role of ABHD11 in lipid metabolism is not known. To understand the biological function of ABHD11, we heterologously expressed the human ABHD11 in budding yeast, Saccharomyces cerevisiae. In vivo [14C]acetate labeling of cellular lipids in yeast cells overexpressing ABHD11 showed a decrease in triacylglycerol content. Overexpression of ABHD11 also alters the molecular species of triacylglycerol in yeast. Similar activity was observed in its yeast homolog, Ygr031w. The role of the conserved lipase motif in the hydrolase activity was proven by the mutation of all conserved amino acid residues of GXSXG motif. Collectively, our results demonstrate that human ABHD11 and its yeast homolog YGR031W have a pivotal role in the lipid metabolism.

RESUMO

PURPOSE: Few studies have compared the effect of Web-based eLearning versus small-group learning on medical student outcomes. Palliative and end-of-life (PEOL) education is ideal for this comparison, given uneven access to PEOL experts and content nationally. METHOD: In 2010, the authors enrolled all third-year medical students at the University of California, Davis School of Medicine into a quasi-randomized controlled trial of Web-based interactive education (eDoctoring) compared with small-group education (Doctoring) on PEOL clinical content over two months. Students participated in three 3-hour PEOL sessions with similar content. Outcomes included a 24-item PEOL-specific self-efficacy scale with three domains (diagnosis/treatment [Cronbach alpha=0.92; CI: 0.91-0.93], communication/prognosis [alpha=0.95; CI: 0.93-0.96], and social impact/self-care [alpha=0.91; CI: 0.88-0.92]); 8 knowledge items; 10 curricular advantage/disadvantages; and curricular satisfaction (both students and faculty). RESULTS: Students were randomly assigned to Web-based eDoctoring (n=48) or small-group Doctoring (n=71) curricula. Self-efficacy and knowledge improved equivalently between groups (e.g., prognosis self-efficacy, 19%; knowledge, 10%-42%). Student and faculty ratings of the Web-based eDoctoring curriculum and the small-group Doctoring curriculum were equivalent for most goals, and overall satisfaction was equivalent for each, with a trend toward decreased eDoctoring student satisfaction. CONCLUSIONS: Findings showed equivalent gains in self-efficacy and knowledge between students participating in a Web-based PEOL curriculum in comparison with students learning similar content in a small-group format. Web-based curricula can standardize content presentation when local teaching expertise is limited, but it may lead to decreased user satisfaction.

RESUMO

The ability of pancreatic ß-cells to undertake glucose-stimulated insulin secretion (GSIS) depends on the generation of adenosine triphosphate (ATP) within the mitochondria from pyruvate, a major rate-limiting enzyme being pyruvate dehydrogenase (PDH) complex (PDC). However, glucose metabolism also controls ß-cell mass. To examine the role of PDC in the regulation of pancreatic ß-cell development and maturation, we generated ß-cell-targeted PDHα subunit knock-out male mice (ß-PDHKO) and compared these with control males (ß-PDHCT) from birth until 6-8 weeks age. Pancreas morphology, transcription factor expression, pancreatic insulin content, and circulating glucose and insulin values were compared. Compared to ß-PDHCT male mice, ß-PDHKO animals had significantly reduced pancreatic insulin content from birth, a lower serum insulin content from day 15, and relative hyperglycemia from day 30. Isolated islets from ß-PDHKO mice demonstrated a reduced GSIS. The number of islets per pancreatic area, mean islet area, and the proportion of islet cells that were ß-cells were all reduced in ß-PDHKO animals. Similarly the number of insulin-immunopositive, extra-islet small endocrine cell clusters, a possible source of ß-cell progenitors, was lower in ß-PDHKO mice. Analysis of pancreatic expression of transcription factors responsible for ß-cell lineage commitment, proliferation, and maturation, Pdx1, Neurogenin3, and NeuroD1 showed that mRNA abundance was reduced in the ß-PDHKO. This demonstrates that PDC is not only required for insulin expression and glucose-stimulated secretion, but also directly influences ß-cell growth and maturity, and positions glucose metabolism as a direct regulator of ß-cell mass and plasticity.

RESUMO

PURPOSE: Prostate cancer screening with prostate-specific antigen (PSA) is a controversial issue. The present study aimed to explore physician behaviors during an unannounced standardized patient encounter that was part of a randomized controlled trial to educate physicians using a prostate cancer screening, interactive, Web-based module. METHODS: Participants included 118 internal medicine and family medicine physicians from 5 health systems in California, in 2007-2008. Control physicians received usual education about prostate cancer screening (brochures from the Center for Disease Control and Prevention). Intervention physicians participated in the prostate cancer screening module. Within 3 months, all physicians saw unannounced standardized patients who prompted prostate cancer screening discussions in clinic. The encounter was audio-recorded, and the recordings were transcribed. Authors analyzed physician behaviors around screening: (1) engagement after prompting, (2) degree of shared decision making, and (3) final recommendations for prostate cancer screening. RESULTS: After prompting, 90% of physicians discussed prostate cancer screening. In comparison with control physicians, intervention physicians showed somewhat more shared decision making behaviors (intervention 14 items vs control 11 items, P <.05), were more likely to mention no screening as an option (intervention 63% vs control 26%, P <.05), to encourage patients to consider different screening options (intervention 62% vs control 39%, P <.05) and seeking input from others (intervention 25% vs control 7%, P<.05). CONCLUSIONS: A brief Web-based interactive educational intervention can improve shared decision making, neutrality in recommendation, and reduce PSA test ordering. Engaging patients in discussion of the uses and limitations of tests with uncertain value can decrease utilization of the tests.

RESUMO

BACKGROUND: Most expert groups recommend shared decision making for prostate cancer screening. Most primary care physicians, however, routinely order a prostate-specific antigen (PSA) test with little or no discussion about whether they believe the potential benefits justify the risk of harm. We sought to assess whether educating primary care physicians and activating their patients to ask about prostate cancer screening had a synergistic effect on shared decision making, rates and types of discussions about prostate cancer screening, and the physician's final recommendations. METHODS: Our study was a cluster randomized controlled trial among primary care physicians and their patients, comparing usual education (control), with physician education alone (MD-Ed), and with physician education and patient activation (MD-Ed+A). Participants included 120 physicians in 5 group practices, and 712 male patients aged 50 to 75 years. The interventions comprised a Web-based educational program for all intervention physicians and MD-Ed+A patients compared with usual education (brochures from the Centers for Disease Control and Prevention). The primary outcome measure was patients' reported postvisit shared decision making regarding prostate cancer screening; secondary measures included unannounced standardized patients' reported shared decision making and the physician's recommendation for prostate cancer screening. RESULTS: Patients' ratings of shared decision making were moderate and did not differ between groups. MD-Ed+A patients reported that physicians had higher prostate cancer screening discussion rates (MD-Ed+A = 65%, MD-Ed = 41%, control=38%; P <.01). Standardized patients reported that physicians seeing MD-Ed+A patients were more neutral during prostate cancer screening recommendations (MD-Ed+A=50%, MD-Ed=33%, control=15%; P <.05). Of the male patients, 80% had had previous PSA tests. CONCLUSIONS: Although activating physicians and patients did not lead to significant changes in all aspects of physician attitudes and behaviors that we studied, interventions that involved physicians did have a large effect on their attitudes toward screening and in the discussions they had with patients, including their being more likely than control physicians to engage in prostate cancer screening discussions and more likely to be neutral in their final recommendations.

RESUMO

BACKGROUND: Shared decision making improves value-concordant decision-making around prostate cancer screening (PrCS). Yet, PrCS discussions remain complex, challenging and often emotional for physicians and average-risk men. OBJECTIVE: In July 2011, the Centers for Disease Control and Prevention convened a multidisciplinary expert panel to identify priorities for funding agencies and development groups to promote evidence-based, value-concordant decisions between men at average risk for prostate cancer and their physicians. DESIGN: Two-day multidisciplinary expert panel in Atlanta, Georgia, with structured discussions and formal consensus processes. PARTICIPANTS: Sixteen panelists represented diverse specialties (primary care, medical oncology, urology), disciplines (sociology, communication, medical education, clinical epidemiology) and market sectors (patient advocacy groups, Federal funding agencies, guideline-development organizations). MAIN MEASURES: Panelists used guiding interactional and evaluation models to identify and rate strategies that might improve PrCS discussions and decisions for physicians, patients and health systems/society. Efficacy was defined as the likelihood of each strategy to impact outcomes. Effort was defined as the relative amount of effort to develop, implement and sustain the strategy. Each strategy was rated (1-7 scale; 7 = maximum) using group process software (ThinkTank(TM)). For each group, intervention strategies were grouped as financial/regulatory, educational, communication or attitudinal levers. For each strategy, barriers were identified. KEY RESULTS: Highly ranked strategies to improve value-concordant shared decision-making (SDM) included: changing outpatient clinic visit reimbursement to reward SDM; development of evidence-based, technology-assisted, point-of-service tools for physicians and patients; reframing confusing prostate cancer screening messages; providing pre-visit decision support interventions; utilizing electronic health records to promote benchmarking/best practices; providing additional training for physicians around value-concordant decision-making; and using re-accreditation to promote training. CONCLUSIONS: Conference outcomes present an expert consensus of strategies likely to improve value-concordant prostate cancer screening decisions. In addition, the methodology used to obtain agreement provides a model of successful collaboration around this and future controversial cancer screening issues, which may be of interest to funding agencies, educators and policy makers.

RESUMO

The offspring of high fat (HF) diet-fed rats display increased body weight during adulthood. However, it is not known whether the changes in appetite regulation in these animals occur in utero or postnatally. We investigated the effects of maternal obesity induced by a HF diet prior to and during pregnancy on leptin and insulin signaling and the expression of orexigenic and anorexigenic peptides in term fetal hypothalami. The consumption of a HF diet prior to and during pregnancy resulted in obesity in HF female rats; additionally, HF female rats exhibited hyperinsulinemia and hyperleptinemia which were exaggerated in late gestation compared with control female rats that were fed a standard rodent laboratory chow (LC). Term fetuses of HF female rats (FHF) also had significantly higher serum leptin and insulin levels compared with control fetuses (FLC) while there was no difference in average fetal weight between the two groups. FHF hypothalami showed elevated levels of mRNA and proteins for leptin long receptor and insulin receptor beta-subunit. However, the protein levels of signal transducers and activators of transcription-3 and insulin receptor substrate-2, the downstream signaling components of leptin and insulin signaling respectively were decreased. Also, FHF hypothalami had increased mRNA levels of neuropeptide Y and agouti-related polypeptide indicating that orexigenic neuropeptides in HF progeny are already upregulated by term fetal stage. Additionally, the mRNA levels of pro-opiatemelanocortin and melanocortin receptor-4 were also increased in the HF fetal hypothalami. These findings indicate potential programming effects of an altered intrauterine environment induced by HF diet consumption on appetite-regulating neuropeptides and leptin and insulin signaling in the late fetal period.

RESUMO

Newborn rat pups artificially raised on a high-carbohydrate (HC) milk formula are chronically hyperinsulinemic and develop adult-onset obesity. As HC rats display aberrations in body weight regulation, hypothalamic adaptations predisposing to obesity have been investigated in this study. The artificial rearing of neonatal rat pups on the HC milk formula resulted in significant increases in the mRNA levels of neuropeptide Y, agouti-related polypeptide, and galanin in the hypothalamus of 12-day-old HC rats. Simultaneously, decreases in the mRNA levels of POMC, melanocortin receptor-4, cocaine- and amphetamine-regulated transcript, and corticotrophin-releasing factor were observed in the hypothalamus of these rats. These changes persisted in 100-day-old HC rats despite weaning onto a rodent diet on postnatal day 24. Marked hyperphagia and increased body weight gain were observed in the post-weaning period. The mRNA levels and protein content of insulin receptor beta (IR-beta) and leptin receptor (long form) showed significant decreases in the hypothalamus of both 12- and 100-day-old HC rats. Further investigation of insulin signaling in the hypothalamus of HC rats indicated significant decreases in the proximal signaling components (insulin receptor substrate proteins 1 and 2 and phosphotidylinositol 3-kinase) in 100-day-old HC rats. These results suggest that hypothalamic neuropeptides respond to the increased carbohydrate availability with associated hormonal alterations during the period of dietary modulation and that these adaptations by persisting in the post-weaning period predispose the HC rats for adult-onset obesity.

RESUMO

When patients are diagnosed with cancer, primary care physicians often must deliver the bad news, discuss the prognosis, and make appropriate referrals. When delivering bad news, it is important to prioritize the key points that the patient should retain. Physicians should assess the patient's emotional state, readiness to engage in the discussion, and level of understanding about the condition. The discussion should be tailored according to these assessments. Often, multiple visits are needed. When discussing prognosis, physicians should be sensitive to variations in how much information patients want to know. The challenge for physicians is to communicate prognosis accurately without giving false hope. All physicians involved in the patient's care should coordinate their key prognosis points to avoid giving the patient mixed messages. As the disease progresses, physicians must reassess treatment effectiveness and discuss the values, goals, and preferences of the patient and family. It is important to initiate conversations about palliative care early in the disease course when the patient is still feeling well. There are innovative hospice programs that allow for simultaneous curative and palliative care. When physicians discuss the transition from curative to palliative care, they should avoid phrases that may convey to the patient a sense of failure or abandonment. Physicians also must be cognizant of how cultural factors may affect end-of-life discussions. Sensitivity to a patient's cultural and individual preferences will help the physician avoid stereotyping and making incorrect assumptions.

RESUMO

OBJECTIVE: Patient-centered care is better achieved through a comprehensive understanding of patients' preferences for how they want to live their life and how they want to influence their own death. Though much has been written on identifying goals of care, it is often difficult for clinicians to articulate patient goals to guide care planning. We explored the literature on patient's preferences for their care in chronic or life-limiting illness to develop a model for assessment of patient perspectives. We then illustrated our model with composite patients from our clinics and we provide questions to guide patient discussion. METHODS: We searched MEDLINE from 1986 to 2004 for primary research articles that relate primarily to a patient's preferences for his or her care. We reviewed over 3500 titles, abstracts, and research papers. Hundreds of articles described patients' quality of life, health status, or satisfaction. We excluded consensus guidelines, non-English papers, reviews, and articles focused on medical professional perspectives. Forty-eight studies focused primarily on patient preferences. Using an iterative process, we identified unique issues and broader themes in patients' desires for their care. RESULTS: Studies focused on patients with cancer, those in hospice or those with terminal disease. Three domains emerged: patient feelings about disease, feelings about suffering, and feelings about the circumstances of death. Attention was given to the differences between patients in terms of the strength and persistence of feelings in each domain. SIGNIFICANCE OF RESULTS: Based on existing data, there are three fundamental domains of patient perspective that influence preferences for care. These domains can be assessed by the care team to guide the development of a plan of care and to identify areas of conflict. Our review identifies gaps in the end-of-life literature and areas for future work in patient preferences.
