RESUMO

BACKGROUND: The Oncotype DX Breast Recurrence Score® assay is a clinically useful tool to determine the benefit of chemotherapy in the treatment of early-stage, hormone-receptor-positive breast cancer. Bilateral breast cancer (BBC) is found in ~ 5% of patients with breast cancer, and data regarding discordance of Oncotype DX results between BBC defined by current TAILORx subgroups are limited. Our goals are to study the rate of Oncotype DX discordance between BBC and investigate whether such differences can affect chemotherapy treatment discussions. METHODS: Patients with BBC were identified in US samples submitted to Genomic Health for 21-gene testing between January 2019 and July 2020. The risk categories were defined as 0-25 and 26-100 as well as 0-17, 18-30, and 31-100 for all patients. Subgroup analysis was also performed for node-negative women age ≤ 50 years with Recurrence Score results of 0-15, 16-20, 21-25, and 26-100. RESULTS: 944 BBC patients with known nodal status (702 node negative, 242 node positive) were identified and included. Among node-negative patients aged > 50 years, the rate of discordance in Recurrence Score by group (0-25 and 26-100) was 4.2% (n = 598). For node-negative patients aged ≤ 50 years, the risk group was discordant in < 3% when considering the risk grouping of 0-25 and 26-100. However, upon subgroup analysis based on TAILORx analysis, the rate of discordance was 48.1% in these younger patients (n = 104). CONCLUSIONS: This study shows that a clinically relevant rate of discordance in Oncotype DX results in patients with BBC may impact medical decision-making regarding chemotherapy.

RESUMO

BACKGROUND AND OBJECTIVE: Recent COVID-19 pandemic guidelines recommend genomic assessment of core biopsies to help guide treatment decisions in estrogen receptor (ER)-positive early-stage breast cancer. Herein we characterize biopsy and excisional breast cancer specimens submitted for 21-gene testing. METHODS: US samples submitted to Genomic Health for 21-gene testing (01/2004-04/2020) were assessed by pathologists and analyzed by a standardized quantitative reverse transcription-polymerase chain reaction. Predefined cutoffs were: ESR1 (positive ≥6.5), PGR (positive ≥5.5), and ERBB2 (negative <10.7). ER status by immunohistochemistry (IHC) and lymph node status were determined locally. Median and interquartile range were reported for continuous variables, and total and percent for categorical variables. Distributions were assessed overall, by age, and by nodal involvement. RESULTS: Of 919 701 samples analyzed, 13% were biopsies and 87% were excisions. Initial assay success rates were 94.5% (biopsies) and 97.3% (excisions). ER IHC concordance with central ESR1 was 96.8% (biopsies) and 97.6% (excisions). Biopsy and excisional medians were: Recurrence Score results 16 (each); ESR1 10.2 (each); PGR 7.7 and 7.6; ERBB2 9.4 and 9.2, respectively. CONCLUSIONS: Biopsy submissions for 21-gene testing are common and consistently generate results that are very similar to the experience with excisions. The 21-gene test can be performed reliably on core biopsies.

RESUMO

Background and Purpose- Dietary sodium reduction with concurrent increase in potassium intake is a current public health priority to reduce risk of cardiovascular events. This study explored associations between the spot urine sodium-to-potassium ratio and cardiovascular events in the MESA (Multi-Ethnic Study of Atherosclerosis) longitudinal cohort. Methods- The MESA is a prospective cohort study of 6814 adults from 4 ethnic groups (European-, Asian-, African- and Hispanic-American) with a mean age of 62 (±10.2) years and an average of 11.7 (±2.2) years of follow-up. Participants were free of clinical cardiovascular disease at baseline. Spot urine sodium and potassium excretion, as a marker of dietary intake, was collected at baseline. The impact of urinary sodium-to-potassium ratio on adjudicated cardiovascular events was assessed using Cox proportional hazards models. Results- Only 39% of MESA participants had a urinary sodium-to-potassium ratio ≤1, and these participants experienced only 74 of the 236 strokes. A sodium-to-potassium ratio >1 was associated with a hazard ratio of 1.47 (95% CI,1.07-2.00) for risk of stroke, adjusting for age, sex, race, cardiovascular risk factors, socio-demographic characteristics, body size, and kidney function. Conclusions- The spot urine sodium-to-potassium ratio (measurable in routine care) is associated with stroke. A urine sodium-to-potassium ratio of ≤1, may be related to a clinically relevant reduction in stroke risk and is a feasible target for health interventions.

RESUMO

Novel technology permits quantification of common carotid artery (CCA) displacement, which is traditionally ignored. We evaluated associations with CCA displacement and cardiovascular disease (CVD) risk and events in a large, multi-ethnic cohort. Right CCA longitudinal displacement (LD), transverse displacement (TD), and grayscale median (GSM) were evaluated using ultrasound speckle-tracking and texture analysis software in 2050 participants. Regression analyses were used to define relationships between CCA LD, TD, GSM, and CVD risk factors. Cox proportional hazards models were used to assess relationships between LD, TD, and incident CVD events. Participants were mean (SD) 64 (10) years old. There were 791 cases with a CVD event over a 12-year median follow-up. The mean LD was 0.29 (0.20) mm. In multivariable models including age, sex, race/ethnicity, heart rate, and CVD risk factors, LD was associated positively with active smoking (ß = 0.08, p < 0.001) and inversely with black (ß = -0.08, p < 0.001), Chinese (ß = -0.05, p < 0.001), and Hispanic (ß = -0.04, p < 0.05) race/ethnicities relative to white individuals, heart rate (ß = -0.03/10 beats/min, p < 0.001), and diastolic blood pressure (ß = -0.01/5 mmHg, p < 0.05). In fully adjusted models, LD and TD were associated with GSM (p < 0.01), but neither predicted incident CVD events (LD: hazard ratio (HR) 0.77 [0.48 to 1.24], p = 0.3; TD: HR 1.12 [0.8 to 1.57], p = 0.5). CCA LD and TD are associated with race/ethnicity and CVD risk factors but not incident CVD events. LD and TD are not measures of arterial stiffness but their association with GSM suggests that lower LD and TD may be related to structural changes within the carotid arterial wall.

RESUMO

Aims: While coronary artery calcium (CAC) has been extensively validated for predicting clinical events, most outcome studies of CAC have evaluated coronary heart disease (CHD) rather than atherosclerotic cardiovascular disease (ASCVD) events (including stroke). Also, virtually all CAC studies are of short- or intermediate-term follow-up, so studies across multi-ethnic cohorts with long-term follow-up are warranted prior to widespread clinical use. We sought to evaluate the contribution of CAC using the population-based MESA cohort with over 10 years of follow-up for ASCVD events, and whether the association of CAC with events varied by sex, race/ethnicity, or age category. Methods and results: We utilized MESA, a prospective multi-ethnic cohort study of 6814 participants (51% women), aged 45-84 years, free of clinical CVD at baseline. We evaluated the relationship between CAC and incident ASCVD using Cox regression models adjusted for age, race/ethnicity, sex, education, income, cigarette smoking status, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, diabetes, lipid-lowering medication, systolic blood pressure, antihypertensive medication, intentional physical exercise, and body mass index. Only the first event for each individual was used in the analysis. Overall, 500 incident ASCVD (7.4%) events were observed in the total study population over a median of 11.1 years. Hard ASCVD included 217 myocardial infarction, 188 strokes (not transient ischaemic attack), 13 resuscitated cardiac arrest, and 82 CHD deaths. Event rates in those with CAC = 0 Agatston units ranged from 1.3% to 5.6%, while for those with CAC > 300, the 10-year event rates ranged from 13.1% to 25.6% across different age, gender, and racial subgroups. At 10 years of follow-up, all participants with CAC > 100 were estimated to have >7.5% risk regardless of demographic subset. Ten-year ASCVD event rates increased steadily across CAC categories regardless of age, sex, or race/ethnicity. For each doubling of CAC, we estimated a 14% relative increment in ASCVD risk, holding all other risk factors constant. This association was not significantly modified by age, sex, race/ethnicity, or baseline lipid-lowering use. Conclusions: Coronary artery calcium is associated strongly and in a graded fashion with 10-year risk of incident ASCVD as it is for CHD, independent of standard risk factors, and similarly by age, gender, and ethnicity. While 10-year event rates in those with CAC = 0 were almost exclusively below 5%, those with CAC ≥ 100 were consistently above 7.5%, making these potentially valuable cutpoints for the consideration of preventive therapies. Coronary artery calcium strongly predicts risk with the same magnitude of effect in all races, age groups, and both sexes, which makes it among the most useful markers for predicting ASCVD risk.

RESUMO

PURPOSE: Only small and short-term studies have evaluated statins in relation to changes in heart structure. We estimated the association between new statin use and 10-year remodeling of the left ventricle. METHODS: The Multi-Ethnic Study of Atherosclerosis collected data on statin use over approximately 10 years, conducting cardiac magnetic resonance (CMR) imaging at baseline and the 10-year exam. Participants were free of baseline cardiovascular disease, and we excluded users of statins at baseline. Statin initiation was defined as a report of current use at any of the 4 subsequent exams. Primary outcomes were the change in left ventricular mass index (LVMI; % predicted by height, weight, and sex) and mass-to-volume ratio. Associations were estimated in a propensity score-matched analysis. RESULTS: A total of 3113 participants (53% female; 40% European-American, 25% African-American, 22% Hispanic-American, and 13% Chinese-American) were eligible; 2431 returned for follow-up CMR imaging after a median of 9.4 years. Statin therapy (moderate dose, 76%) was started by 36% of participants (N = 872). We excluded 42 participants with incident myocardial infarction. Compared with nonuse, statin use was associated with less 10-year progression in LVMI (-2.35 percentage points; 95% CI, -4.24 to -0.47; P = .01) and mass-to-volume ratio (-0.03 absolute difference; 95% CI, -0.07 to -0.00; P = .02); effects were small in magnitude. A dose response was observed: Higher statin dose was associated with less LVMI progression. CONCLUSIONS: In contrast to previous small studies, we found very modest associations between statin use and indices of left ventricular remodeling over 10 years in this prospective study of a diverse cohort.

RESUMO

AIMS: To evaluate the 2013 American Heart Association (AHA)-American College of Cardiology (ACC)-Atherosclerotic Cardiovascular Disease (ASCVD) risk score among four different race/ethnic groups and to ascertain which factors are most associated with risk overestimation by the AHA-ACC-ASCVD score. METHODS AND RESULTS: The Multi-Ethnic Study of Atherosclerosis (MESA), a prospective community-based cohort, was used to examine calibration and discrimination of the AHA-ACC-ASCVD risk score in 6441 White, Black, Chinese, and Hispanic Americans (aged 45-79 years and free of known ASCVD at baseline). Using univariable and multivariable absolute risk regression, we modelled the impact of individual risk factors on the discordance between observed and predicted 10-year ASCVD risk. Overestimation was observed in all race/ethnic groups in MESA and was highest among Chinese (252% for women and 314% for men) and lowest in White women (72%) and Hispanic men (67%). Higher age, Chinese race/ethnicity (when compared with White), systolic blood pressure (treated and untreated), diabetes, alcohol use, exercise, lipid-lowering medication, and aspirin use were all associated with more risk overestimation, whereas family history was associated with less risk overestimation in a multivariable model (all P < 0.05). CONCLUSION: The AHA-ACC-ASCVD risk score overestimates ASCVD risk among men, women, and all four race/ethnic groups evaluated in a modern American primary prevention cohort. Clinicians treating patients similar to those in MESA, particularly older individuals and those with factors associated with more risk overestimation, may consider interpreting absolute ASCVD risk estimates with caution.

RESUMO

OBJECTIVE: Vitamin K-dependent proteins (VKDPs), which require post-translational modification to achieve biological activity, seem to contribute to thrombus formation, vascular calcification, and vessel stiffness. Whether VKDP activity is prospectively associated with incident cardiovascular disease has not been studied. APPROACH AND RESULTS: VKDP activity was determined by measuring circulating des-γ-carboxy prothrombin concentrations in a random sample of 709 multiethnic adults free of cardiovascular disease drawn from the Multi-Ethnic Study of Atherosclerosis (MESA). Lower des-γ-carboxy prothrombin concentrations reflect greater VKDP activity. Subjects were followed up for the risk of ischemic cardiovascular disease (coronary heart disease, stroke, and fatal cardiovascular disease) for 11.0 years of follow-up. A total of 75 first ischemic CVD events occurred during follow-up. The incidence of ischemic cardiovascular disease increased progressively across des-γ-carboxy prothrombin quartiles, with event rates of 5.9 and 11.7 per 1000 person-years in the lowest and highest quartiles. In analyses adjusted for traditional cardiovascular risk factors and measures of vitamin K intake, a doubling of des-γ-carboxy prothrombin concentration was associated with a 1.53 (95% confidence interval, 1.09-2.13; P=0.008) higher risk of incident ischemic cardiovascular disease. The association was consistent across strata of participants with diabetes mellitus, hypertension, renal impairment, and low vitamin K nutritional intake. CONCLUSIONS: In this sample of middle-aged and older adults, VKDP activity was associated with incident ischemic cardiovascular events. Further studies to understand the role of this large class of proteins in cardiovascular disease are warranted.

RESUMO

The U.S. female criminal justice (CJ) population is rapidly growing, yet large-scale studies exploring gender-specific HIV risk behaviors in the CJ population are lacking. This analysis uses baseline data on adults with a CJ history from eight U.S. studies in an NIH-funded "Seek, Test, Treat, Retain" harmonization consortium. Data were collected using a standardized HIV risk behavior assessment tool and pooled across studies to describe participants' characteristics and risk behaviors. Multilevel mixed-effects logistic regression models were used to test for gender-based behavior differences. Among 784 HIV-positive (21.4% female) and 5521 HIV-negative (8.5% female) participants, HIV-positive women had higher odds than HIV-positive men of engaging in condomless sexual intercourse (AOR 1.84 [1.16-2.95]) with potentially sero-discordant partners (AOR 2.40 [1.41-4.09]) and of sharing injection equipment (AOR 3.36 [1.31-8.63]). HIV risk reduction interventions targeting CJ-involved women with HIV are urgently needed as this population may represent an under-recognized potential source of HIV transmission.

RESUMO

Owing to its aggressive course, triple-negative breast cancer remains an important clinical issue of current interest compared with hormone-receptor positive subtypes. Recent research has focused on determining the optimal local therapy (breast conversation therapy vs mastectomy) for this cancer subtype. In this overview, we examine outcomes based on immunohistochemistry, gene expression profiles, type of local therapy and in the era of neoadjuvant chemotherapy. Based on multiple observational reports risk for locoregional recurrence appears to be similar to reported outcomes in other subtypes. However, distant recurrence continues to be a significant concern for triple-negative breast cancer, indicating the need for better systemic therapies. To date, insufficient evidence exists to determine whether breast conserving therapy or mastectomy results in superior outcomes.

RESUMO

BACKGROUND: In the general population, the majority of cardiovascular events occur in people at the low to moderate end of population risk distribution. The 2013 American College of Cardiology/American Heart Association guideline on the treatment of blood cholesterol recommends consideration of statin therapy for adults with an estimated 10-year atherosclerotic cardiovascular disease (ASCVD) risk ≥7.5% based on traditional risk factors. Whether use of nontraditional risk markers can improve risk assessment in those below this threshold for statin therapy is unclear. METHODS AND RESULTS: Using data from the Multi-Ethnic Study of Atherosclerosis (MESA), a population sample free of clinical CVD at baseline, we calibrated the Pooled Cohort Equations (cPCE). ASCVD was defined as myocardial infarction, coronary heart disease death, or fatal or nonfatal stroke. Adults with an initial cPCE <7.5% and elevated levels of additional risk markers (abnormal test) whose new calculated risk was ≥7.5% were considered statin eligible: low-density lipoprotein cholesterol ≥160 mg/dL; family history of ASCVD; high-sensitivity C-reactive protein ≥2 mg/dL; coronary artery calcium score ≥300 Agatston units or ≥75th percentile for age, sex, and ethnicity; and ankle-brachial index <0.9. We compared the absolute and relative ASCVD risks among those with versus without elevated posttest estimated risk. We calculated the number needed to screen to identify 1 person with abnormal test for each risk marker, defined as the number of participants with baseline cPCE risk <7.5% divided by the number with an abnormal test reclassified as statin eligible. Of 5185 participants not taking statins with complete data (age, 45-84 years), 4185 had a cPCE risk <7.5%. During 10 years of follow-up, 57% of the ASCVD events (183 of 320) occurred among adults with a cPCE risk <7.5%. When people with diabetes mellitus were excluded, the coronary artery calcium criterion reclassified 6.8% upward, with an event rate of 13.3%, absolute risk of 10%, relative risk of 4.0 (95% confidence interval [CI], 2.8-5.7), and number needed to screen of 14.7. The corresponding numbers for family history of ASCVD were 4.6%, 15.1%, 12%, 4.3 (95% CI, 3.0-6.4), and 21.8; for high-sensitivity C-reactive protein criteria, 2.6%, 10%, 6%, 2.6 (95% CI, 1.4-4.8), and 39.2; for ankle-brachial index criteria, 0.6%, 9%, 5%, 2.3 (95% CI, 0.6-8.6), and 176.5; and for low-density lipoprotein cholesterol criteria, 0.5%, 5%, 1%, 1.2 (95% CI, 0.2-8.4), and 193.3, respectively. Of the 3882 with <7.5% cPCE risk, 431 (11.1%) were reclassified to ≥7.5% (statin eligible) by at least 1 of the additional risk marker criteria. CONCLUSIONS: In this generally low-risk population sample, a large proportion of ASCVD events occurred among adults with a 10-year cPCE risk <7.5%. We found that the coronary artery calcium score, high-sensitivity C-reactive protein, family history of ASCVD, and ankle-brachial index recommendations by the American College of Cardiology/American Heart Association cholesterol guidelines (Class IIB) identify small subgroups of asymptomatic population with a 10-year cPCE risk <7.5% but with observed ASCVD event rates >7.5% who may warrant statin therapy considerations.

RESUMO

BACKGROUND: Accurate risk assessment of atherosclerotic cardiovascular disease (ASCVD) is essential to effectively balance the risks and benefits of therapy for primary prevention. OBJECTIVE: To compare the calibration and discrimination of the new American Heart Association (AHA) and American College of Cardiology (ACC) ASCVD risk score with alternative risk scores and to explore preventive therapy as a cause of the reported risk overestimation using the AHA-ACC-ASCVD score. DESIGN: Prospective epidemiologic study of ASCVD. SETTING: MESA (Multi-Ethnic Study of Atherosclerosis), a community-based, sex-balanced, multiethnic cohort. PATIENTS: 4227 MESA participants aged 50 to 74 years and without diabetes at baseline. MEASUREMENTS: Observed and expected events for the AHA-ACC-ASCVD score were compared with 4 commonly used risk scores-and their respective end points-in MESA after a 10.2-year follow-up. RESULTS: The new AHA-ACC-ASCVD and 3 older Framingham-based risk scores overestimated cardiovascular events by 37% to 154% in men and 8% to 67% in women. Overestimation was noted throughout the continuum of risk. In contrast, the Reynolds Risk Score overestimated risk by 9% in men but underestimated risk by 21% in women. Aspirin, lipid-lowering or antihypertensive therapy, and interim revascularization did not explain the overestimation. LIMITATION: Comparability of MESA with target populations for primary prevention and possibility of missed events in MESA. CONCLUSION: Of the 5 risk scores, 4, including the new AHA-ACC-ASCVD score, showed overestimation of risk (25% to 115%) in a modern, multiethnic cohort without baseline clinical ASCVD. If validated, overestimation of ASCVD risk may have substantial implications for individual patients and the health care system. PRIMARY FUNDING SOURCE: National Heart, Lung, and Blood Institute.

RESUMO

We report an evidence-based management algorithm for benign lymphoepithelial cysts (BLEC) of the parotid glands in HIV patients based on long-term outcomes after radiation therapy. From 1987 to 2013, 72 HIV-positive patients with BLEC of the parotid glands treated at our institutions were identified and their medical records were reviewed and analyzed. The primary endpoint of our study was to determine a dose response in HIV patients with BLEC. In group A (≤18 Gy), which received a median dose of 10 Gy (8-18), overall response (OvR), complete response (CR), partial response (PR), and local failure (LF) was experienced by 7, 7, 0, and 93 %, respectively. In group B (≥22.5 Gy), which received a median dose of 24 Gy (22.5-30), OvR, CR, PR, and LF was experienced by 88, 65, 23, and 12 %. Logistic regression revealed that higher dose (≥22.5 Gy) predicted for cosmetic control (p = 0.0003). Multiple regression analysis revealed higher dose predicted for cosmetic control (p = 0.0001) after adjusting for confounding variables (age, gender, race, HAART use, BLEC duration, and fractionation size). No patients in either group experienced RTOG grade ≥3 toxicities. A radiation dose of 24 Gy delivered in 12-16 fractions of 1.5-2 Gy per fraction provides long-term cosmetic control in HIV-positive patients with BLEC of the parotid glands.

RESUMO

BACKGROUND: The impact of replacing the National Cholesterol Education Program (NCEP)/Adult Treatment Program (ATP) III cholesterol guidelines with the new 2013 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines for primary prevention of cardiovascular disease is unclear. METHODS: We used risk factor and 10-year clinical event rate data from MESA, combined with estimates of efficacy of moderate and high-intensity statin therapy from meta-analyses of statin primary prevention trials to estimate (a) the change in number of subjects eligible for drug therapy and (2) the anticipated reduction in atherosclerotic cardiovascular disease (ASCVD) events and increment in type 2 diabetes mellitus (T2DM) associated with the change in cholesterol guidelines. RESULTS: Of the 6,814 MESA participants, 5,437 were not on statins at baseline and had complete data for analysis (mean age 61.4±10.3). Using the NCEP/ATP III guidelines, 1,334 (24.5%) would have been eligible for statin therapy compared with 3,015 (55.5%) under the new ACC/AHA guidelines. Among the subset of newly eligible, 127/1,742 (7.3%) had an ASCVD event during 10years of follow-up. Assuming 10years of moderate-intensity statin therapy, the estimated absolute reduction in ASCVD events for the newly eligible group was 2.06% (number needed to treat [NNT] 48.6) and the estimated absolute increase in T2DM was 0.90% (number needed to harm [NNH] 110.7). Assuming 10years of high-intensity statin therapy, the corresponding estimates for reductions in ASCVD and increases in T2DM were as follows: ASCVD 2.70% (NNT 37.5) and T2DM 2.60% (NNH 38.6). The estimated effects of moderate-intensity statins on 10-year risk for ASCVD and T2DM in participants eligible for statins under the NCEP/ATP III were as follows: 3.20% (NNT 31.5) and 1.06% (NNH 94.2), respectively. CONCLUSION: Substituting the NCEP/ATP III cholesterol guidelines with the 2013 ACC/AHA cholesterol guidelines in MESA more than doubled the number of participants eligible for statin therapy. If the new ACC/AHA cholesterol guidelines are adopted and extend the primary prevention population eligible for treatment, the risk-benefit profile is much better for moderate-intensity than high-intensity statin treatment.

RESUMO

OBJECTIVES: To determine the association of HIV, immunologic, and inflammatory factors on coronary artery calcium (CAC), a marker of subclinical atherosclerosis. METHODS: Cross-sectional study comparing baseline data of males from Hawaii Aging with HIV - Cardiovascular Study (HAHCS) with the Multi-Ethnic Study of Atherosclerosis (MESA) cohort. The cohorts were pooled to determine effects of HIV on CAC and explore immunologic and inflammatory factors that may explain development of CAC in HIV. Multivariable regression models compared CAC prevalence in HAHCS with MESA adjusting for coronary heart disease (CHD) risk profiles. RESULTS: We studied 100 men from HAHCS and 2733 men from MESA. Positive CAC was seen in 58% HAHCS participants and 57% MESA participants. Mean CAC was 260.8 in HAHCS and 306.5 in MESA. Using relative risk (RR) regression, HAHCS participants had a greater risk (RR = 1.20, P < 0.05) of having positive CAC than MESA when adjusting for age, smoking status, diabetes, antihypertensive therapy, BMI, systolic blood pressure, total cholesterol, and HDL cholesterol. Among participants with positive CAC, HIV infection was not associated with larger amounts of CAC. Among HAHCS participants, current HIV viral load, CD4, length of HIV, interleukin 6 (IL-6), fibrinogen, C-reactive protein (CRP), and D-dimer were not associated with the presence or amount of CAC. DISCUSSION: HIV was independently associated with a positive CAC in men with increased likelihood occurring between 45 and 50 years of age. Current HIV viral load, CD4 count, length of HIV, and inflammatory markers were unrelated to either presence or amount of CAC.

RESUMO

Obesity is associated with respiratory dysfunction. It is a key risk and contributory factor in the sleep related breathing disorders, obstructive sleep apnoea/hypopnoea syndrome (OSAHS) and obesity hypoventilation syndrome (OHS). Weight management is an integral part of the management of these disorders, in addition to continuous positive airways pressure (CPAP) and non-invasive ventilation (NIV). Untreated, these conditions are associated with a high disease burden and as treatment is effective, early recognition and referral is critical. Best practice in on-going care is multidisciplinary.

RESUMO

Health disparities along with insufficient numbers of healthcare providers and resources have created a need for effective and efficient grassroots approaches to improve community health. Community-based participatory research (CBPR), more specifically the utilization of community health advisors (CHAs), is one such strategy. The Getting on Target with Community Health Advisors (GOTCHA) project convened an interdisciplinary team to answer the call from 10 counties in the rural Mississippi Delta area of 'The Stroke Belt' to meet the region's identified health needs, and to impact the health of a disparaged state. This article explores this CBPR project including the community involvement strategies, innovative CHA training curriculum, evaluation plan, and implications to healthcare professionals, particularly nurses.

RESUMO

The term frailty is being increasingly used by clinicians, however there is no strict consensus on the best screening method. The expectation in England is that all older patients should have the Clinical Frailty Scale (CFS) completed on admission. This will frequently rely on junior medical staff and nurses, raising the question as to whether there is consistency. We asked 124 members of a multidisciplinary team (consultants, junior doctors, nurses, and allied health professionals; physiotherapists, occupational therapists, dietitians, speech and language therapists) to complete the CFS for seven case scenarios. The majority of the participants, 91/124 (72%), were trainee medical staff, 16 were senior medical staff, 12 were allied health professions, and 6 were nurses. There was broad agreement both between the professions and within the professions, with median CFS scores varying by a maximum of only one point, except in case scenario G, where there was a two-point difference between the most junior trainees (FY1) and the nursing staff. No difference (using the Mann-Whitney U test) was found between the different staff groups, with the median scores and range of scores being similar. This study has confirmed there is agreement between different staff members when calculating the CFS with no specific preceding training.
