RESUMO

OBJECTIVES: Only few studies evaluated whether hurricane preparedness impacts health. The PREPARE study addresses this gap. METHODS: We recruited participants who had pertinent pre-hurricane data from the San Juan Overweight Adults Longitudinal Study (SOALS: n=364) and 125 patients with diabetes from Federally Qualified Health Center (COSSMA) in Puerto Rico. Participants aged 42-75 years completed interviews 20-34 months after Hurricanes Irma and Maria. We evaluated associations between self-reported hurricane preparedness and health and other related associations using logistic regression controlling for age, location, education and interview date. RESULTS: Only 41% of participants reported high pre-hurricane preparedness; 25% reported gaps (moderate/low availability) in information and 48% reported gaps in resources for hurricane preparedness. Participants reporting lower pre-hurricane preparedness had higher reported hurricane-related detrimental health impact (OR=1.96; 95% CI: 1.31, 2.95) and higher odds (OR=2.07; 95% CI: 0.92, 4.68) of developing new non-communicable disease (NCD) compared to others. Post-hurricane drinking water disruption for ≥ 3 months versus none or less (OR=2.76; 95% CI: 1.39, 5.47) and similarly diet changes due to cooking/refrigeration access (OR=1.96; 95% CI: 1.24, 3.07), and diet changes for ≥ 20 months due to finances/access to shops (OR=2.83; 95% CI: 1.85, 4.32) were also associated with detrimental health impact. CONCLUSION: Lower preparedness was associated with higher detrimental impact of the hurricanes on overall health, and marginally significant impact on NCD. Future preparedness efforts could especially target means of coping with disruption of water services and regular diet, as these were also associated with detrimental health impact.

RESUMO

Nitrate-reducing oral bacteria have gained a lot of interest due to their involvement in nitric oxide (NO) synthesis and its important cardiometabolic outcomes. Consortia of nitrate-metabolizing oral bacteria associated with cardiometabolic health and cognitive function have been recently identified. Longitudinal studies and clinical trials have shown that chronic mouthwash use is associated with increased blood pressure and increased risk for prediabetes/diabetes and hypertension. Concurrently, recent studies are beginning to shed some light on the complexity of nitrate reduction pathways of oral bacteria, such as dissimilatory nitrate reduction to ammonium (DNRA), which converts nitrite into ammonium, and denitrification, which converts nitrite to NO, nitrous oxide, and dinitrogen. These pathways can affect the composition and metabolism of the oral microbiome; consequently, salivary nitrate and nitrite metabolism have been proposed as targets for probiotics and oral health. These pathways could also affect systemic NO levels because NO generated through denitrification can be oxidized back to nitrite in the saliva, thus facilitating flux along the NO3--NO2--NO pathway, while DNRA converts nitrite to ammonium, leading to reduced NO. It is, therefore, important to understand which pathway predominates under different oral environmental conditions, since the clinical consequences could be different for oral and systemic health. Recent studies show that oral hygiene measures such as tongue cleaning and dietary nitrate are likely to favor denitrifying bacteria such as Neisseria, which are linked with better cardiometabolic health. A vast body of literature demonstrates that redox potential, carbon-to-nitrate ratio, and nitrate-to-nitrite ratio are key environmental drivers of the competing denitrification and DNRA pathways in various natural and artificial ecosystems. Based on this information, a novel behavioral and microbial model for nitric oxide metabolism and health is proposed, which links lifestyle factors with oral and systemic health through NO metabolism.

RESUMO

AIMS: To assess the level of agreement between point-of-care and laboratory reference glucose values in defining glycaemic status. METHODS: We analysed 1292 overweight/obese, non-institutionalized participants, aged 40-65 years, in the San Juan Overweight Adults Longitudinal Study. Fasting venous blood glucose was determined using a point-of-care Bayer Contour Blood Glucose Meter and by Vitros System 250 instrument (laboratory). American Diabetes Association thresholds were used to classify participants into normoglycaemia (< 5.6 mmol/l), prediabetes (5.6 to 6.9 mmol/l), or diabetes groups (≥ 7 mmol/l). RESULTS: Bland-Altman plot analysis showed a slope of 0.04 (P=0.002) for the regression between the mean difference and the average of the two methods. The slopes were significantly different from zero among people with normoglycaemia (ß=-0.57, P<0.001), and prediabetes (ß=-0.75, P<0.001) but not among people with diabetes (ß=-0.02, P=0.68). When the prediabetes and diabetes groups were merged into one group, the slope was 0.01, and the glucose values remained similar using the two methods (P=0.76). CONCLUSION: Point-of-care blood glucose measurement may be useful to screen people with diabetes, and to assess glucose among individuals with diabetes where blood can be drawn, but laboratory tests are unavailable or untimely.

RESUMO

In this paper, we report theoretical electron impact ionization cross sections from threshold to 2000 eV for isocarbonic open chain molecules C4H6, C4H8, C4F6 including their isomers, and closed chain molecules c-C4H8 and c-C4F8. Theoretical formalism employed presently, viz., Complex Scattering Potential-ionization contribution method has been used successfully for a variety of polyatomic molecules. The present ionization calculations are very important since results available for the studied targets are either scarce or none. Our work affords comparison of C4 containing hydrocarbon versus fluorocarbon molecules. Comparisons of the present ionization cross sections are made wherever possible, and new ionization data are also presented.

RESUMO

UNLABELLED: The Puerto Rican Elderly Dental Health Study is the first to evaluate the periodontal status of a representative sample in Puerto Rico. OBJECTIVE: To assess the periodontal status among the elderly population in San Juan. BASIC RESEARCH DESIGN: Three dentists were trained and standardised by the US National Health and Nutrition Examination Survey (NHANES) reference examiner. They examined elders aged 70-97 in the San Juan area from participants in a representative cohort of the Puerto Rican elderly. Probing depth (PD), attachment loss (AL), and tooth mobility were assessed among the dentate participants on 4 sites on all teeth excluding third molars. We used the CDC-AAP definitions for moderate periodontitis (> or = 2 teeth with AL > or = 4mm at interproximal sites or > or = 2 teeth with PD > or = 5mm at interproximal sites) and severe periodontitis (> or = 2 teeth with AL > or = 6mm at interproximal sites and > or = 1 teeth with PD > or = 5mm at interproximal sites). RESULTS: The participation rate was 47%, 183 individuals, mean age 77.9 (sd 5.9), and 67% were females. Mean number of teeth was 15.8 (sd 6.8), and tooth mobility was present in 18% of participants. Mean PD was 1.5 (sd 0.6) and mean AL was 2.8 mm (sd1.5). The prevalence of moderate and severe periodontitis (CDC-AAP) was 44.5% compared to 20.7% in the NHANES 1999-2004 survey among 75 years and older. CONCLUSIONS: Our study showed high levels of severe and moderate periodontal disease among Puerto Rican older adults. Further research is needed to understand the reasons for the high prevalence.

RESUMO

The association between fluoride and risk for osteosarcoma is controversial. The purpose of this study was to determine if bone fluoride levels are higher in individuals with osteosarcoma. Incident cases of osteosarcoma (N = 137) and tumor controls (N = 51) were identified by orthopedic physicians, and segments of tumor-adjacent bone and iliac crest bone were analyzed for fluoride content. Logistic regression adjusted for age and sex and potential confounders of osteosarcoma was used to estimate odds ratios (OR) and 95% confidence intervals (CI). There was no significant difference in bone fluoride levels between cases and controls. The OR adjusted for age, gender, and a history of broken bones was 1.33 (95% CI: 0.56-3.15). No significant association between bone fluoride levels and osteosarcoma risk was detected in our case-control study, based on controls with other tumor diagnoses.

RESUMO

BACKGROUND AND AIMS: Impaired glucose tolerance based on 2-h glucose levels is more predictive of future cardiovascular disease and more sensitive in detecting earlier diabetes compared to impaired fasting glucose. However, the 1-h OGTT may be even more sensitive than the 2-h. We assessed the relative value of 1-h OGTT by exploring its relationship with adiposity and other measures of glucose homeostasis. METHODS AND RESULTS: Ninety four overweight/obese individuals free of diabetes and major cardiovascular conditions were included in the analyses. We adjusted for age, gender, smoking status and physical activity. One-h OGTT showed similar partial correlations with fasting glucose and 2-h OGTT (r=0.60 and 0.64 respectively). Fasting glucose, fasting insulin and HOMA correlated better with 1-h OGTT (r=0.60, 0.47 and 0.52) than with 2-h OGTT (r=0.50, 0.41, and 0.45). BMI and waist circumference also showed stronger correlation with 1-h (r=0.31, 0.29), compared to 2-h OGTT (r=0.16, 0.16) or fasting glucose (r=0.23, 0.22). Metabolic syndrome was associated similarly with 1-h and 2-h OGTT. CONCLUSIONS: The 1-h OGTT correlates well with both fasting glucose and 2-h OGTT and shows similar or higher associations with obesity measures. The 1-h OGTT has potential utility in epidemiologic studies.

RESUMO

BACKGROUND: Ascertainment of periodontal disease using self-reported measures would be useful for large epidemiologic studies. This study evaluates whether a combination of self-reported items with established risk factors in a predictive model can assess periodontal disease accurately. METHODS: Responses of 246 subjects to a detailed questionnaire were compared to their periodontal disease history as assessed from radiographs. Multiple regression modeling was used to construct predictive models using self-reported items and established risk factors. RESULTS: Depending on the definition of gold-standard periodontal disease, two or three self-reported items were selected for the predictive models, in addition to age, gender, and smoking. Self-reported tooth mobility was associated strongly with periodontal disease independent of other risk factors and was selected in all models. For dichotomous definitions of periodontal disease, discrimination of predictive logistic regression models was good with areas under the receiver operating characteristic curve >0.80. Assessment of periodontal disease history based on extreme quantiles of model-predicted values yielded high sensitivity and specificity. CONCLUSION: The combination of several self-reported items may be useful for ascertainment of periodontal disease in epidemiologic studies.

RESUMO

Data on the dose-dependent effects of smoking and smoking cessation on tooth loss are scarce. We hypothesized that smoking has both dose- and time-dependent effects on tooth loss incidence. We used longitudinal data on tobacco use and incident tooth loss in 43,112 male health professionals, between 1986 and 2002. In multivariate Cox models, current smokers of 5 to 14 and 45+ cigarettes daily had a two-fold (HR, 1.94; 95% CI, 1.72, 2.18) and three-fold (HR, 3.05; 95% CI, 2.38, 3.90) higher risk of tooth loss, respectively, compared with never-smokers. Risk decreased with increasing time since cessation, but remained elevated by 20% (95% CI, 16%, 25%) for men who had quit 10+ years before. Current pipe/cigar smokers had a 20% (95% CI, 1.11, 1.30) increased risk of tooth loss compared with never- and former smokers of pipes/cigars.

RESUMO

Osteosarcoma incidence patterns suggest an aetiologic role for perinatal factors, and growth and development. Osteosarcoma patients (n = 158) and controls with benign orthopaedic conditions (n = 141) under age 40 were recruited from US orthopaedic surgery departments. Exposures were ascertained by interview, birth, and growth records. Age- and sex-adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated. Current height and age- and sex-specific height percentiles were not associated with osteosarcoma risk. Male cases, however, appeared to have an earlier adolescent growth period, and earlier attainment of final height (OR = 7.1; 95% CI = 1.6-50 for <19 vs 19+ years), whereas earlier puberty appeared protective with ORs of 0.41 (95% CI 0.18-0.89) and 0.68 (95% CI 0.31-1.5) for developing facial and pubic hair, respectively. High birth weight was associated with an elevated osteosarcoma risk (OR = 3.9; CI = 1.7-10 for 4000 g vs 3000-3500 g), although there was no trend in risk with increasing weight. These data provide some evidence that osteosarcoma is related to size at birth and in early adolescence, while earlier puberty in male subjects may be protective.

RESUMO

Self-report is an efficient and accepted means of assessing many population characteristics, risk factors, and diseases, but has rarely been used for periodontal disease (chronic periodontitis). The availability of valid self-reported measures of periodontal disease would facilitate epidemiologic studies on a much larger scale, allow for integration of new studies of periodontal disease within large ongoing studies, and facilitate lower-cost population surveillance of periodontitis. Several studies have been conducted to validate self-reported measures for periodontal disease, but results have been inconsistent. In this report, we conducted a systematic review of the validation studies. We reviewed the 16 studies that assessed the validity of self-reported periodontal and gingivitis measures against clinical gold standards. Seven of the studies included self-reported measures specific to gingivitis, four included measures only for periodontitis, and five included both gingivitis and periodontal measures. Three of the studies used a self-assessment method where they provided the patient with a detailed manual for performing a self-exam. The remaining 13 studies asked participants to self-report symptoms, presence of periodontal disease itself, or their recollection of a dental health professional diagnosing them or providing treatment for periodontal disease. The review indicates that some measures showed promise, but results varied across populations and self-reported measures. One example of a good measure is, "Has any dentist/hygienist told you that you have deep pockets?", which had a sensitivity of 55%, a specificity of 90%, positive predictive value of 77%, and negative predictive value of 75% against clinical pocket depth. Higher validity could be potentially obtained by the use of combinations of several self-reported questions and other predictors of periodontal disease.

RESUMO

Periodontal disease is a chronic infection of the gums characterized by a loss of attachment between the tooth and bone, and by bone loss. We evaluated cross-sectionally the association between periodontal disease and C-reactive protein (CRP), fibrinogen, factor VII, tissue plasminogen activator (t-PA), LDL-C, von Willebrand factor, and soluble tumor necrosis factor receptors 1 and 2. The final sample consisted of 468 men (ages 47-80 yrs), participating in the Health Professional Follow-up Study, who provided blood and were free of CVD, diabetes, and cancer. In multivariate regression models controlling for age, cigarette smoking, alcohol intake, physical activity, and aspirin intake, self-reported periodontal disease was associated with significantly higher levels of CRP (30% higher among periodontal cases compared with non-cases), t-PA (11% higher), and LDL-C (11% higher). Based on our data, periodontal disease showed significant associations with biomarkers of endothelial dysfunction and dyslipidemia, which may potentially mediate the association between periodontal and cardiovascular disease.

RESUMO

Alcohol consumption impairs neutrophil, macrophage, and T-cell functions, increasing the likelihood of infections. We examined the association between alcohol consumption and periodontitis, prospectively, among 39,461 male health professionals aged 40 to 75 years and free of periodontitis at the start of follow-up. Alcohol intake was assessed at baseline and updated every 4 years by a food-frequency questionnaire. Periodontal disease status was self-reported and validated against radiographs. Multivariate analysis was adjusted for age, smoking, diabetes, body-mass index, physical activity, time period, and caloric intake. During 406,160 person-years of follow-up, there were 2125 cases of periodontitis. Compared with non-drinkers, the relative risk (95% confidence interval) among men reporting usual alcohol intake of 0.1-4.9 g/day was 1.24 (1.09, 1.42); 5.0 to 14.9 g/day, 1.18 (1.04, 1.35); 15 to 29.9 g/day, 1.18 (1.01, 1.38); and > 30 g/day, 1.27 (1.08, 1.49). The results suggest that alcohol consumption is an independent modifiable risk factor for periodontitis.

RESUMO

OBJECTIVES: To examine seasonal variations in the presentation of acute necrotising ulcerative gingivitis (ANUG) in a previously unstudied population in Cape Town, South Africa. DESIGN: A descriptive study of all presenting cases of ANUG at a health center over 6 years; patients were examined at one point in time. SETTING: A clinic-based cross-sectional study was carried out among patients presenting routinely to the oral medicine clinic at the University of the Western Cape. Patients at this clinic were mostly colored and black people, and were of low socioeconomic status. SUBJECTS AND METHODS: All patients presenting to the periodontal clinic were examined during the period from 15 March 1992 to 15 March 1998 and interviews were conducted. A comprehensive clinical intra-oral and peri-oral examination was carried out using a dental mirror and blunt probe by three trained calibrated dental examiners. The minimum criteria for inclusion as an ANUG patient were painful, bleeding gums with irreversible destruction of the interdental papillae (cratering) and marginal gingiva. Patients with multiple small ulcerations not restricted to the gingiva, but including other oral sites such as the tongue and buccal mucosa were diagnosed as herpetic stomatitis. Other distinguishing characteristics of ANUG included presence of a pseudomembrane, odor, a strange taste in the mouth, and hypersalivation. Swabs and biopsies taken to verify the diagnosis when necessary. If there was any doubt as to the diagnosis of the lesion it was not included among the ANUG cases. MAIN OUTCOME MEASURE: Presence of ANUG. RESULTS: Among the 19944 patients presenting for periodontal treatment, 684 were found to have ANUG. The ANUG patients consisted of 58% males; 73% of the ANUG patients were between the ages of 5 to 12 years. The majority of ANUG patients presented during the summer (55.4%), 27.7% in autumn and 8.4% during both winter and spring. Significant differences were evident between the numbers seen during the different seasons. CONCLUSIONS: This study demonstrated a significant seasonal variation in the occurence of ANUG in Cape Town, South Africa.

RESUMO

BACKGROUND: Many constituents of fruits and vegetables may reduce the risk for coronary heart disease, but data on the relationship between fruit and vegetable consumption and risk for coronary heart disease are sparse. OBJECTIVE: To evaluate the association of fruit and vegetable consumption with risk for coronary heart disease. DESIGN: Prospective cohort study. SETTING: The Nurses' Health Study and the Health Professionals' Follow-Up Study. PARTICIPANTS: 84 251 women 34 to 59 years of age who were followed for 14 years and 42 148 men 40 to 75 years who were followed for 8 years. All were free of diagnosed cardiovascular disease, cancer, and diabetes at baseline. MEASUREMENTS: The main outcome measure was incidence of nonfatal myocardial infarction or fatal coronary heart disease (1127 cases in women and 1063 cases in men). Diet was assessed by using food-frequency questionnaires. RESULTS: After adjustment for standard cardiovascular risk factors, persons in the highest quintile of fruit and vegetable intake had a relative risk for coronary heart disease of 0.80 (95% CI, 0.69 to 0.93) compared with those in the lowest quintile of intake. Each 1-serving/d increase in intake of fruits or vegetables was associated with a 4% lower risk for coronary heart disease (relative risk, 0.96 [CI, 0.94 to 0.99]; P = 0.01, test for trend). Green leafy vegetables (relative risk with 1-serving/d increase, 0.77 [CI, 0.64 to 0.93]), and vitamin C-rich fruits and vegetables (relative risk with 1-serving/d increase, 0.94 [CI, 0.88 to 0.99]) contributed most to the apparent protective effect of total fruit and vegetable intake. CONCLUSIONS: Consumption of fruits and vegetables, particularly green leafy vegetables and vitamin C-rich fruits and vegetables, appears to have a protective effect against coronary heart disease.

RESUMO

Oral and pharyngeal cancer (OC) mortality is very low in Greece, especially among men, compared to other European countries. We conducted a case-control study of OC in Athens, and obtained information on tobacco, alcohol use and other potential risk factors and confounding variables for 110 incident cases and 115 hospital-based controls. We used multivariate logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Tobacco smoking (pack years, P(trend)=0.01) and alcohol use (drinks/week, P(trend)=0.07) were independent risk factors, with a multiplicative effect for combined exposures (OR, 8.3; 95% CI, 2.4-29.1, for >28 alcohol drinks/week and >50 pack years of cigarette smoking). The type of alcoholic beverage also seemed important: drinking ouzo and tsipouro (liquors of high ethanol concentration) was associated with greater increased OC risk than drinking comparable amounts of wine, beer or dark spirits. While alcohol drinking is more common for male cases versus controls, few men reported regularly consuming large quantities of ethanol associated with highest risk of OC in other studies. This may partially explain the low rates of male OC mortality in Greece. Among the 38% of our cases who were women, however, neither smoking nor alcohol drinking frequencies were significantly elevated compared to controls, and so the etiology of OC risk in females requires further investigation.

RESUMO

BACKGROUND: Frequent consumption of fruit and vegetables has been associated with a reduced risk of colorectal cancer in many observational studies. METHODS: We prospectively investigated the association between fruit and vegetable consumption and the incidence of colon and rectal cancers in two large cohorts: the Nurses' Health Study (88 764 women) and the Health Professionals' Follow-up Study (47 325 men). Diet was assessed and cumulatively updated in 1980, 1984, 1986, and 1990 among women and in 1986 and 1990 among men. The incidence of cancer of the colon and rectum was ascertained up to June or January of 1996, respectively. Relative risk (RR) estimates were calculated with the use of pooled logistic regression models accounting for various potential confounders. All statistical tests were two-sided. RESULTS: With a follow-up including 1 743 645 person-years and 937 cases of colon cancer, we found little association of colon cancer incidence with fruit and vegetable consumption. For women and men combined, a difference in fruit and vegetable consumption of one additional serving per day was associated with a covariate-adjusted RR of 1.02 (95% confidence interval [CI] = 0.98-1.05). A difference in vegetable consumption of one additional serving per day was associated with an RR of 1.03 (95% CI = 0.97-1.09). Similar results were obtained for women and men considered separately. A difference in fruit consumption of one additional serving per day was associated with a covariate-adjusted RR for colon cancer of 0.96 (95% CI = 0.89-1.03) among women and 1. 08 (95% CI = 1.00-1.16) among men. For rectal cancer (total, 244 cases), a difference in fruit and vegetable consumption of one additional serving per day was associated with an RR of 1.02 (95% CI = 0.95-1.09) in men and women combined. None of these associations was modified by vitamin supplement use or smoking habits. CONCLUSIONS: Although fruits and vegetables may confer protection against some chronic diseases, their frequent consumption does not appear to confer protection from colon or rectal cancer.

RESUMO

BACKGROUND: Studies of hospitalized and institutionalized older adults suggest a relationship between poor oral health and subsequent weight loss. Given the association between weight loss and subsequent mortality and morbidity, we evaluated how oral health problems contributed to significant weight loss over a 1-year period among a representative sample of community-dwelling older adults. METHODS: The study population consisted of 563 adults aged 70 years and older living at home in rural and urban areas in six New England states. Baseline data included information regarding health status, functional status, physical activity, disease diagnoses, lifestyle behaviors, and cognitive and affective status. Dentists performed oral health assessments. One year later, participants were called and asked questions regarding their health and dietary practices and their current weight. RESULTS: Over the 1-year period of follow-up, approximately one third of the sample had lost 4% or more of their previous total body weight; 6% of men and 11% of women lost 10% or more of their previous body weight. Of the subjects, 37% were edentulous; most of these individuals wore full dentures. With gender, income, advanced age, and baseline weight controlled for, edentulousness remained an independent risk factor for significant weight loss (odds ratio 1.63 for 4% weight loss and 2.03 for 10% weight loss). Individuals with increasing numbers of posterior teeth and functional units were at slightly lower risk for weight loss; however, these associations did not reach statistical significance. CONCLUSIONS: Dentate status is an important risk factor for clinically significant weight loss among community-dwelling older adults.
