Swallowing disorders in head and neck cancer patients treated with radiotherapy and adjuvant chemotherapy

The nature of swallowing problems was examined in nine patients treated primarily with external‐beam radiation and adjuvant chemotherapy for newly diagnosed tumors of the head and neck. All subjects underwent videofluorographic examination of their swallowing. Three analyses were completed, including the following: observations of motility disorders, residue, and aspiration; temporal analyses; and biomechanical analyses. Oropharyngeal swallow efficiency was calculated for the first swallow of each bolus.

A Screening Procedure for Oropharyngeal Dysphagia

Abstract. The present study was designed to examine the sensitivity and specificity of a 28-item screening test in identifying patients who aspirate, have an oral stage disorder, a pharyngeal delay, or a pharyngeal stage disorder. The screening test includes 28 items divided into 5 categories: (1) 4 medical history variables; (2) 6 behavioral variables; (3) 2 gross motor variables; (4) 9 observations from oromotor testing; and (5) 7 observations during trial swallows. Results identified variables that were able to classify patients correctly as having or not having aspiration 71% of the time, an oral stage disorder 69% of the time, a pharyngeal delay 72% of the time, and a pharyngeal stage swallowing problem 70% of the time. Sensitivity and specificity for each of these judgments and all 28 items on the test are also provided. Results are discussed relative to statistical, clinical, and third-party perspectives on the goals of screening, data from other screening tests, and the role of screening versus diagnostic testing in care of dysphagic patients.

Longitudinal assessment of quality of life in laryngeal cancer patients

Although quality of life (QL) and performance status are important outcomes in head and neck (HN) cancer, there is little systematic inclusion of these parameters in treatment trials.

Consistently Stable or Decreased Body Mass Index in Young Adulthood and Longitudinal Changes in Metabolic Syndrome Components The Coronary Artery Risk Development in Young Adults Study

Background— Data are sparse regarding the association of stable body mass index (BMI) over the long term with metabolic syndrome components in young adults. Methods and Results— Participants in the Coronary Artery Risk Development in Young Adults Study, including white and black adults 18 to 30 years of age at the initial examination in 1985 to 1986, were stratified into groups by baseline BMI and change in BMI (stable/decreased, increased >2 kg/m2, or fluctuating) across all 6 examinations between years 0 and 15 of the study. Changes in metabolic syndrome components were compared between groups. Among 1358 men and 1321 women, 16.3% maintained a stable BMI, 73.9% had an increased BMI, and 9.8% had a fluctuating BMI. Over 15 years, participants with stable BMI had essentially unchanged levels of metabolic syndrome components, regardless of baseline BMI, whereas those with increased BMI had progressively worsening levels. For example, men with a baseline BMI of 20.0 to 24.9 kg/m2 and stable BMI during follow-up had a mean increase of only 15 mg/dL in fasting triglycerides over 15 years compared with 65 mg/dL (P<0.001) in those whose BMI increased. Incidence of metabolic syndrome at year 15 was lower in the stable BMI group (2.2%) compared with the increased BMI group (18.8%; P<0.001). Conclusions— Adverse progression of metabolic syndrome components with advancing age may not be inevitable. Young adults who maintained stable BMI over time had minimal progression of risk factors and lower incidence of metabolic syndrome regardless of baseline BMI. Greater public health efforts should be aimed at long-term weight stabilization.

Association of Fitness in Young Adulthood With Survival and Cardiovascular Risk: The Coronary Artery Risk Development in Young Adults (CARDIA) Study

IMPORTANCE Although cardiorespiratory fitness (CRF) is prognostic in older adults, the effect of CRF during early adulthood on long-term cardiovascular structure, function, and prognosis is less clear. OBJECTIVE To examine whether CRF in young adults is associated with long-term clinical outcome and subclinical cardiovascular disease (CVD). DESIGN, SETTING, AND PARTICIPANTS Prospective study of 4872 US adults aged 18 to 30 years who underwent treadmill exercise testing at a baseline study visit from March 25, 1985, to June 7, 1986, and 2472 individuals who underwent a second treadmill test 7 years later. Median follow-up was 26.9 years, with assessment of obesity, left ventricular mass and strain, coronary artery calcification (CAC), and vital status and incident CVD. Follow-up was complete on August 31, 2011, and data were analyzed from recruitment through the end of follow-up. MAIN OUTCOMES AND MEASURES The presence of CAC was assessed by computed tomography at years 15 (2000-2001), 20 (2005-2006), and 25 (2010-2011), and left ventricular mass was assessed at years 5 (1990-1991) and 25 (with global longitudinal strain). Incident CVD and all-cause mortality were adjudicated. RESULTS Of the 4872 individuals, 273 (5.6%) died and 193 (4.0%) experienced CVD events during follow-up. After comprehensive adjustment, each additional minute of baseline exercise test duration was associated with a 15% lower hazard of death (hazard ratio [HR], 0.85; 95% CI, 0.80-0.91; P < .001) and a 12% lower hazard of CVD (HR, 0.88; 95% CI, 0.81-0.96; P = .002). Higher levels of baseline CRF were associated with significantly lower left ventricular mass index (β = -0.24; 95% CI, -0.45 to -0.03; P = .02) and significantly better lobal longitudinal strain (β = -0.09; 95% CI, -0.14 to -0.05; P < .001) at year 25. Fitness was not associated with CAC. A 1-minute reduction in fitness by year 7 was associated with 21% and 20% increased hazards of death (HR, 1.21; 95% CI, 1.07-1.37; P = .002) and CVD (HR, 1.20; 95% CI, 1.06-1.37; P = .006), respectively, along with a more impaired strain (β = 0.15; 95% CI, 0.08-0.23; P < .001). No association between change in fitness and CAC was found. CONCLUSIONS AND RELEVANCE Higher levels of fitness at baseline and improvement in fitness early in adulthood are favorably associated with lower risks for CVD and mortality. Fitness and changes in fitness are associated with myocardial hypertrophy and dysfunction but not CAC. Regular efforts to ascertain and improve CRF in young adulthood may play a critical role in promoting cardiovascular health and interrupting early CVD pathogenesis.

Genetic ancestry in lung-function predictions

BACKGROUND Self-identified race or ethnic group is used to determine normal reference standards in the prediction of pulmonary function. We conducted a study to determine whether the genetically determined percentage of African ancestry is associated with lung function and whether its use could improve predictions of lung function among persons who identified themselves as African American. METHODS We assessed the ancestry of 777 participants self-identified as African American in the Coronary Artery Risk Development in Young Adults (CARDIA) study and evaluated the relation between pulmonary function and ancestry by means of linear regression. We performed similar analyses of data for two independent cohorts of subjects identifying themselves as African American: 813 participants in the Health, Aging, and Body Composition (HABC) study and 579 participants in the Cardiovascular Health Study (CHS). We compared the fit of two types of models to lung-function measurements: models based on the covariates used in standard prediction equations and models incorporating ancestry. We also evaluated the effect of the ancestry-based models on the classification of disease severity in two asthma-study populations. RESULTS African ancestry was inversely related to forced expiratory volume in 1 second (FEV(1)) and forced vital capacity in the CARDIA cohort. These relations were also seen in the HABC and CHS cohorts. In predicting lung function, the ancestry-based model fit the data better than standard models. Ancestry-based models resulted in the reclassification of asthma severity (based on the percentage of the predicted FEV(1)) in 4 to 5% of participants. CONCLUSIONS Current predictive equations, which rely on self-identified race alone, may misestimate lung function among subjects who identify themselves as African American. Incorporating ancestry into normative equations may improve lung-function estimates and more accurately categorize disease severity. (Funded by the National Institutes of Health and others.)

Healthy Lifestyle Through Young Adulthood and the Presence of Low Cardiovascular Disease Risk Profile in Middle Age The Coronary Artery Risk Development in (Young) Adults (CARDIA) Study

Background —A low cardiovascular disease (CVD) risk profile (untreated cholesterol < 200 mg/dl, untreated blood pressure < 120/<80 mmHg, never smoking, and no history of diabetes and myocardial infarction) in middle age is associated with markedly better health outcomes in older age, but few middle aged adults have this low risk profile. We examined whether adopting a healthy lifestyle throughout young adulthood is associated with presence of the low CVD risk profile in middle age. Methods and Results —The CARDIA study sample consisted of 3,154 black and white participants aged 18 to 30 years at Year 0 (Y0, 1985-86) who attended the Year 0, 7 and 20 (Y0, Y7 and Y20) examinations. Healthy lifestyle factors (HLFs) defined at Y0, Y7 and Y20 included: 1) Average BMI 2 ; 2) No or moderate alcohol intake; 3) higher healthy diet score; 4) higher physical activity score; and 5) Never smoking. Mean age (25 years) and percentage of women (56%) were comparable across groups defined by number of HLFs. The age-, sex- and race-adjusted prevalences of low CVD risk profile at Y20 were 3.0%, 14.6%, 29.5%, 39.2% and 60.7% for people with 0 or 1, 2, 3, 4, and 5 HLFs, respectively (p-trend <0.0001). Similar graded relationships were observed for each sex-race group (all p-trend<0.0001). Conclusions —Maintaining a healthy lifestyle throughout young adulthood is strongly associated with low CVD risk profile in middle age. Public health and individual efforts are needed to improve adoption and maintenance of healthy lifestyles in young adults.Background— A low cardiovascular disease risk profile (untreated cholesterol <200 mg/dL, untreated blood pressure <120/<80 mm Hg, never smoking, and no history of diabetes mellitus or myocardial infarction) in middle age is associated with markedly better health outcomes in older age, but few middle-aged adults have this low risk profile.

Higher dietary intake of long-chain ω-3 polyunsaturated fatty acids is inversely associated with depressive symptoms in women

OBJECTIVE Experimental and observational data suggest that a higher dietary intake of long-chain omega-3 polyunsaturated acids may lead to a decreased risk of depressive disorders. We assessed multivariable-adjusted associations of fish consumption and dietary intakes of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) with depressive symptoms in a population-based sample of 3317 African-American and Caucasian men and women from the Coronary Artery Risk Development in Young Adults study. METHODS Diet was assessed in year 7 (1992-1993) and depressive symptoms were measured in years 10 (1995-1996), 15 (2000-2001), and 20 (2005-2006) by the 20-item Center for Epidemiological Studies Depression Scale. Depressive symptoms were defined as a Center for Epidemiological Studies Depression Scale score > or =16 or self-reported use of antidepressant medication. RESULTS In the entire cohort, the highest quintiles of intakes of EPA (> or =0.03% energy), DHA (> or =0.05% energy), and EPA + DHA (> or =0.08% energy) were associated with a lower risk of depressive symptoms at year 10 (P for trends = 0.16, 0.10, and 0.03, respectively). The observed inverse associations were more pronounced in women. For the total number of occasions with depressive symptoms, the multivariable adjusted odds ratios (95% confidence interval) in women were 0.75 (0.55-1.01) for fish intake, 0.66 (0.50-0.89) for EPA, 0.66 (0.49-0.89) for DHA, and 0.71 (0.52-0.95) for EPA + DHA when comparing the highest with the lowest quintiles. Analyses of continuous Center for Epidemiological Studies Depression Scale scores revealed inverse associations with fourth-root-transformed omega-3 variables in women. CONCLUSION Our findings suggest that dietary intakes of fish and long-chain omega-3 fatty acids may be inversely associated with chronic depressive symptoms in women.

Incidence and patient characteristics associated with silent aspiration in the acute care setting

Abstract. Coughing is a physiologic response to aspiration in normal healthy individuals. However, there are published records that report no cough in response to aspiration (i.e., silent aspiration) in dysphagic patients. In this retrospective study, for more than 2 years in two acute care hospitals we examined frequency of the cough response in patients identified as aspirators by using videofluoroscopy. One thousand one hundred one patients underwent videofluorographic evaluation of their swallowing during this 2-year period; 469 aspirated; 276 were silently aspirating. Two hundred twenty-four of these silent aspirators aspirated once during a swallow and 52 silently aspirated more than once during a swallow. These two groups of patients were analyzed separately. Univariate (chi-square and Fishers exact tests) and multivariate (logistic regression) analyses were conducted to assess the relationship of silent aspiration to age, gender, medical diagnosis, timing of aspiration, and etiology of aspiration. In univariate analysis, age (p < 0.001), gender (p < 0.004), and medical diagnosis (p= 0.05) were significantly associated with silent aspiration in the group who aspirated once during a swallow. No significant associations were seen in the group of patients who aspirated more than once during a swallow.
