Long-Term Outcomes and Prognostic Factors in Kidney Transplant Recipients with Polycystic Kidney Disease.

Polycystic kidney disease (PKD) accounts for approximately 15% of kidney transplants, but long-term outcomes in patients with PKD who have received a kidney transplant are not well understood. In primary recipients of kidney transplants at our center (1994-2014), we compared outcomes of underlying PKD (N=619) with other native diseases (non-PKD, N=4312). Potential factors influencing outcomes in PKD were evaluated using Cox proportional-hazards regression and a rigorous multivariable model. Patients with PKD were older and were less likely to be sensitized or to experience delayed graft function (DGF). Over a median follow-up of 5.6 years, 1256 of all recipients experienced death-censored graft failure (DCGF; 115 patients with PKD) and 1617 died (154 patients with PKD). After adjustment for demographic, dialysis, comorbid disease, surgical, and immunologic variables, patients with PKD had a lower risk of DCGF (adjusted hazard ratio [aHR], 0.73; 95% CI, 0.57 to 0.93; P=0.01) and death (aHR, 0.62; 95% CI, 0.51 to 0.75; P<0.001). In our multiadjusted model, calcineurin-inhibitor (CNI) use was associated with lower risk of DCGF (aHR, 0.45; 95% CI, 0.26 to 0.76; P=0.003), whereas HLA mismatch of five to six antigens (aHR, 2.1; 95% CI, 1.2 to 3.64; P=0.009) was associated with higher likelihood of DCGF. Notably, both pretransplant coronary artery disease (CAD) and higher BMI were associated with increased risk of death (CAD, aHR, 2.5; 95% CI, 1.69 to 3.71; P<0.001; per 1 kg/m2 higher BMI, aHR, 1.07; 95% CI, 1.04 to 1.11; P<0.001), DCGF, and acute rejection. Nephrectomy at time of transplant and polycystic liver disease were not associated with DCGF/death. Incidence of post-transplant diabetes mellitus was similar between PKD and non-PKD cohorts. Recipients with PKD have better long-term graft and patient survival than those with non-PKD. Standard practices of CNI use and promoting HLA match are beneficial in PKD and should continue to be promoted. Further prospective studies investigating the potential benefits of CNI use and medical/surgical interventions to address CAD and the immunologic challenges of obesity are needed.

Association between adherence to the French dietary guidelines and the risk of type 2 diabetes

ObjectiveFrench food-based dietary guidelines (FBDG) were updated in 2017. The objective of this prospective study was to estimate the associations between the Programme National Nutrition Santé–guidelines score 2 (PNNS-GS2), reflecting the level of adherence to the 2017 FBDG, and the risk of type 2 diabetes (T2D). MethodsA total of 79 205 French adult participants (mean age: 41.5 y [SD = 14.5]; 78.5% were women; 65% were postgraduate) from the NutriNet-Santé cohort (2009–2019) were included. Dietary intakes were collected using repeated 24-h dietary records. The PNNS-GS2 (theorical range: -∞ to 14.25), including six adequacy components and seven moderation components as well as a penalization on energy intake, was computed.The association between the PNNS-GS2 (as quintiles [Q]) and T2D risk was estimated using multivariable Cox proportional hazard models accounting for sociodemographic, anthropometric, and lifestyle and health-related factors. ResultsDuring an average follow-up of 6.7 y (536 679 person-years), 676 T2D cases occurred. In the multiadjusted model, participants with the highest PNNS-GS2 (higher adherence to the 2017 FBDG), compared with those with the lowest (lower adherence to FBDG), exhibited a 49% reduction in risk of T2D (HRQ5 versus Q1: 0.51, 95% CI: 0.37, 0.69). Body mass index accounted for up to 27% of the main association. The healthy profiles of the cohort's participants may have reduced statistical power. ConclusionsIn this large, prospective cohort study, a higher adherence to the French 2017 FBDG was strongly and inversely associated with the risk of developing T2D. Such analysis should be confirmed in other settings, but in terms of public health and nutritional policy, this study supports the relevance of the 2017 French FBDG.

Non-alcoholic fatty liver disease, Mediterranean diet and 10-year cardiovascular disease incidence: the mediating role of adiponectin. Highlights from the ATTICA prospective (2002–2012) study

Abstract Background/Introduction The most updated set of guidelines (EASL-EASD-EASO 2016) suggests Mediterranean diet as a promising dietary pattern for non-alcoholic fatty liver disease (NAFLD) management. Purpose The association between NAFLD and adherence to Mediterranean diet as well as their interaction on 10-year fatal/non fatal cardiovascular disease incidence were evaluated. Methods Study population included 1,514 men and 1,528 women (&amp;gt;18 years old) in our city in Greece, free of CVD recruited during the 2001–2002 period. Liver steatosis and fibrosis assessment indices were calculated at baseline and specific cut-offs were used to capture NAFLD. Level of adherence to Mediterranean diet was assessed through MedDietScore. National and international food databases were used to estimate total daily carbohydrate intake. The cut-off point of 35% of total daily energy intake was set to define low vs. high carbohydrate intake. Circulating adiponectin level was measured at baseline (4.0 (2.0) μg/mL). Results MedDietScore was inversely associated with NAFLD indices of both steatosis and fibrosis yet only in Triglycerides-Glucose index [Odds Ratio (OR)3rd vs. 1st MedDietScore tertile = 0.53, 95% Confidence Interval (95% CI) (0.29, 0.95)] persisted in multi-adjusted models including adjustments for metabolic syndrome components, energy intake and overall and central obesity. This was more evident in men (p for sex interaction = 0.03). The protective role of Mediterranean diet was retained irrespective to the total carbohydrate content; however, sex-based stratified analysis revealed that in woman subsample only Mediterranean diet with low carbohydrate content (i.e. &amp;lt;35%) had an independent protective role against NAFLD presence [OR3rd vs. 1st MedDietScore tertile = 0.79, 95% CI (0.40, 0.96)]. NAFLD predicted CVD [Hazard Ratio (HR) = 3.01, 95% CI (2.28, 3.95)] in crude model as well as in multi-adjusted model [HR=1.37, 95% CI (1.10, 2.10)]. NAFLD effect on CVD remained significant only in MedDietScore below median [HR=1.38, 95% CI (1.00, 1.93)] whereas it was essentially null [HR=1.00, 95% CI (0.38, 2.63)] among subjects with lower score. Mediation analysis revealed that adiponectin was the strongest mediator of the examined associations. In particular, per 1 mg/dL serum adiponectin about 21% lower likelihood to have NAFLD was observed. Stratified analysis using the median value of adiponectin level (4.1 mg/dL) revealed that the inverse association between Mediterranean diet and NAFLD reached the level of significance only in case of adiponectin levels over the median values (OR (3rd vs. 1st MedDietScore tertile) = 0.69 95% CI (0.35, 0.98)). Conclusion Beyond the inverse association between Mediterranean diet and NAFLD several novelties were revealed; low-carbohydrate Mediterranean diet was more protective against NAFLD in women while an adiponectin-related mechanism was revealed.

Predictors of Olfactory Decline in Aging: A Longitudinal Population-Based Study.

BackgroundOlfactory dysfunction is common in aging and associated with dementia and mortality. However, longitudinal studies tracking change in olfactory ability are scarce. We sought to identify predictors of interindividual differences in rate of olfactory identification change in aging.MethodParticipants were 1780 individuals, without dementia at baseline and with at least 2 olfactory assessments over 12 years of follow-up (mean age = 70.5 years; 61.9% female), from the Swedish National Study on Aging and Care in Kungsholmen (SNAC-K). Odor identification was assessed with the Sniffin’ Sticks. We estimated the impact of demographic, health, and genetic factors on rate of olfactory change with linear mixed effect models.ResultsAdvancing age, manufacturing profession, history of cerebrovascular disease, higher cardiovascular disease burden, diabetes, slower walking speed, higher number of medications, and the APOE ε4 allele were associated with accelerated odor identification decline (ps < .014). Multi-adjusted analyses showed unique associations of age, diabetes, and ε4 to olfactory decline (ps < .017). In 1531 participants who remained free of dementia (DSM IV criteria) during follow-up, age, cardiovascular disease burden, and diabetes were associated with accelerated decline (ps < .011). Of these, age and diabetes remained statistically significant in the multi-adjusted model (ps < .001).ConclusionDemographic, vascular, and genetic factors are linked to rate of decline in odor identification in aging. Although some olfactory loss may be an inevitable part of aging, our results highlight the importance of vascular factors for the integrity of the olfactory system, even in the absence of dementia.

High sensitivity C-reactive protein and risk of migraine in a 11-year follow-up with data from the Nord-Tr\xf8ndelag health surveys 2006\u20132008 and 2017\u20132019

BackgroundSeveral previous studies have reported a cross-sectional association between elevated high sensitivity C-reactive protein (hs-CRP) and migraine. The aim of this population-based follow-up study was to investigate the influence of hs-CRP at baseline on the risk of developing migraine 11 years later.MethodsData from the Nord-Trøndelag Health Study performed in 2006–2008 (baseline) and 2017–2019 were used. A total of 19,574 participants without migraine at baseline were divided into three groups based on hs-CRP levels (< 3 mg/L, 3–9.99 mg/L and 10.00–20 mg/L). Poisson regression was used to evaluate the associations between hs-CRP levels and risk ratios (RRs) of migraine, and precision of the estimates was assessed by 95% confidence interval (CIs).ResultsIn the multi-adjusted model, increased risk of migraine (RR 1.46, 95% CI 1.05–2.04) was found in the highest hs-CRP levels group compared to the lowest group. In the group with the highest hs-CRP levels, a nearly three times higher risk of chronic migraine (RR 2.81, 95% CI 1.12–7.06) was found, whereas no evident relationship was found between high hs-CRP level and risk of developing episodic migraine.ConclusionsThe main finding in this 11-year follow-up was that hs-CRP levels between 10.00–20.00 mg/L at baseline was associated with increased risk of chronic migraine.

The association between sleep duration and chronic diseases: a population-based cross-sectional study

ObjectivesTo examine the cross-sectional relationship between sleep duration and 11 chronic diseases (risk of obesity, depression, diabetes, asthma, COPD, arthritis, kidney, CHD, stroke, and cancer [excluding skin cancer]) by using data from Behavioral Risk Factor Surveillance System. MethodsUsing data from the 2013, 2014 and 2016 Behavioral Risk Factor Surveillance System, a total sample consisted of 1,191,768 participants. Logistic regression models were constructed to calculate OR and 95% confidence intervals (CI) for the association between sleep duration and 11 chronic diseases. In addition, we also conducted subgroup analysis based on age and gender. ResultsIn multi-adjusted model, the positive association between extremely short or long sleep duration and risk of chronic diseases was significant (P < 0.05) with the exception of skin cancer (P = 0.14 and P = 0.43). There are stronger association between extremely short or long sleep duration and obesity, diabetes, asthma, chronic obstructive pulmonary disease, arthritis, kidney, coronary heart disease, stroke, and cancer in women and aged 18–64 years old. ConclusionsOur results indicated a higher risk of common chronic diseases due to short or long sleep duration in women and aged 18–64 years. Further studies are needed to demonstrate these association.

Long-term prognostic significance of the ST level and ST slope in the 12‑lead ECG in the general population

BackgroundEven minor ST depression in the electrocardiogram (ECG) is associated with cardiovascular disease and increased mortality. There is limited data on the prognostic significance of ST-level changes in the general population. Subjects and methodsA random sample of Finnish subjects (n = 6354) aged over 30 years (56.1% women) underwent a health examination including a 12‑lead ECG in the Health 2000 survey. The effects of relative ST level as a continuous variable and ST slope (upsloping, horizontal, downsloping) in three different lead groups were analyzed using a multi-adjusted Cox proportional hazard model separately for men and women with total mortality as endpoint. ResultsThe follow-up lasted for 13.7 (SD 3.3) years for men and 13.9 (SD 3.1) years for women. Lower lateral ST levels were associated with all-cause mortality in multi-adjusted models in both genders (at J + 80 ms hazard ratio [HR] 0.64 for a change of 1.0 mm [95% confidence interval 0.49–0.84, p = 0.002] for men and HR 0.61 [0.48–0.78, p < 0.001] for women). Associated coronary heart disease had no major influence on the results. Exclusion of subjects with ECG signs of left ventricular hypertrophy from the analyses increased the mortality risk of lower lateral ST levels in men but decreased it in women. For the anterior and inferior lead groups, no statistically significant difference was seen after multivariate adjustment. ST slope was not an independent predictor of mortality after multivariate adjustment. ConclusionLower ST level in the lateral ECG leads is an independent prognostic factor to predict all-cause mortality in the general population.

Association between Eating Away from Home and Hyperuricemia: A Population-Based Nationwide Cross-Sectional Study in China.

Hyperuricemia (HU) is a risk factor for different kinds of chronic noncommunicable diseases, and eating away from home (EAFH) may play an important role in their development, which has been ignored greatly so far. This study aimed to investigate the association between EAFH and HU in different models. A cross-sectional study involving 8,322 participants of the China Health and Nutrition Survey (CHNS) was conducted. Logistic regression models were used to analyze the data. We found that participants who consumed more away-from-home food had a higher risk for HU, and the adjusted odds ratio (aOR) and 95% confidence interval (CI) (for each increment in grades of EAFH) were 1.11 (1.02, 1.20) in a multiadjusted model (adjusted for age, gender, province, net individual income, body mass index, smoking, leisure-time physical activities, energy intake, and sleep duration). As for stratified analyses, the aOR (95% CI) of EAFH was 1.12 (1.01, 1.24) for men and 1.06 (0.92, 1.21) for women. Similar results can be found in the middle-aged and obese population, with aOR (95% CI) of EAFH as 1.17 (1.05, 1.30) and 1.15 (1.03, 1.29), respectively. In conclusion, EAFH is positively associated with the prevalence of HU.

Specific nutrient patterns are associated with higher structural brain integrity in dementia-free older adults

Optimal nutrition may play a beneficial role in maintaining a healthy brain. However, the relationship between nutrient intake and brain integrity is largely unknown. We investigated the association of specific nutrient dietary patterns with structural characteristics of the brain. Within the population-based Swedish National study on Aging and Care-Kungsholmen (SNAC-K), a cross-sectional study of 417 dementia-free participants aged ≥60 years who underwent structural magnetic resonance imaging (MRI) scans during 2001–2003, was carried-out. Data on dietary intake were collected using a food frequency questionnaire, from which intake of 21 nutrients was estimated. By principal component analysis, five nutrient patterns were extracted: (1) NP1 was characterized by fiber, vitamin C, E, β-carotene, and folate [Fiber&Antioxidants], (2) NP2 by eicosapentaenoic (EPA, 20:5 ω-3) and docosahexaenoic (DHA, 22:6 ω-3) polyunsaturated fatty acids (PUFAs), proteins, cholesterol, vitamin B3, B12, and D [long chain (LC) ω-3PUFAs&Proteins], (3) NP3 by α-linoleic (18:2 ω-6) and α-linolenic (18:3 ω-3) PUFAs, monounsaturated fatty acids (MUFAs), and vitamin E [MUFAs&ω-3,6PUFAs], (4) NP4 by saturated fatty acids (SFAs), trans fats, MUFAs, and cholesterol [SFAs&Trans fats], (5) NP5 by B-vitamins, retinol, and proteins [B-Vitamins&Retinol]. Nutrient patterns scores were tertiled with the lowest tertile as reference, and were related to total brain volume (TBV) and white matter hyperintensities volume (WMHV) using linear regression models adjusting for potential confounders. In the multi-adjusted model, compared to the lowest intake for each pattern, the highest intake of NP1 (β = 11.11, P = 0.009), NP2 (β = 7.47, P = 0.052), and NP3 (β = 10.54, P = 0.005) was associated with larger TBV whereas NP5 was related to smaller TBV (β = −12.82, P = 0.001). The highest intake of NP1 was associated with lower WMHV (β = −0.32, P = 0.049), whereas NP4 was associated with greater WMHV (β = 0.31, P = 0.036). In sum, our results suggest that the identified brain-health specific nutrient combinations characterized by higher intake of fruit, vegetables, legumes, olive and seed oils, fish, lean red meat, poultry and low in milk and dairy products, cream, butter, processed meat and offal, were strongly associated with greater brain integrity among older adults.

Impact of family communication on self-rated health of couples who visited primary care physicians: A cross-sectional analysis of Family Cohort Study in Primary Care.

IntroductionSelf-rated health (SRH) is a subjective health measurement that predicts mortality and morbidity and reflects mental health and socioeconomic status. Since a couple’s relationship can influence the health status of the individuals involved, poor family communication can negatively influence the health status of its members. The aim of this study was to investigate the factors affecting SRH among married couples in primary care and evaluated the effect of family communication on SRH.Material and methodsIn this cross-sectional analysis of Family Cohort Study in Primary Care, 469 couples (938 participants) were analyzed to evaluate the relationship between SRH and family communication. Participants answered questionnaires on demographic characteristics and lifestyle factors. The Korean version of the Family Communication Scale of Family Adaptation and Cohesion Evaluation Scale-IV was used to assess family communication, and a 5-point scale of SRH questions was used to assess the SRH status. Multivariate logistic regression analyses were performed in order to evaluate the relationship between family communication and SRH and identify associated factors for good SRH.ResultsWives with a high family communication level had higher OR for good SRH. When the husband and wife both reported high family communication levels, the OR for good SRH increased in wives; however, the relationship between family communication and SRH was not significant in husbands. In the multi-adjusted model, the OR for good SRH of husbands increased in those with >12 years of education, moderate drinkers and decreased in current smokers. The OR for good SRH of wives increased in those with age of 60 to 69, those with >12 years of education, and those who participated in vigorous physical activity, and decreased in those with diabetes and depressive mood.ConclusionsOur results indicate that improvement in family communication may contribute to better SRH.

Environmental factors and risk of delirium in geriatric patients: an observational study

BackgroundPatients with delirium have increased risk of death, dementia and institutionalization, and prognosis differs between delirium motor subtypes. A few studies have identified associations between environmental factors like room-transfers and time spent in the emergency department (ED) and delirium, but no studies have investigated if environmental factors may influence delirium motor subtypes. We wanted to explore if potentially stressful events like ward-transfers, arriving ED at nighttime, time spent in ED and nigthttime investigations were associated with development of delirium (incident delirium) and delirium motor subtypes.MethodsWe used the DSM-5 criteria to diagnose delirium and the Delirium Motor Subtype Scale for motor subtyping. We defined hyperactive and mixed delirium as delirium with hyperactive symptoms, and hypoactive and no-subtype delirium as delirium without hyperactive symptoms. We registered ward-transfers, time of arrival in ED, time spent in ED and nighttime investigations (8 p.m. to 8 a.m.), and calculated Global Deterioration Scale (GDS) and Cumulative Illness Rating Scale (CIRS) to adjust for cognitive impairment and comorbidity. We used logistic regression analyses with incident delirium and delirium with hyperactive symptoms as outcome variables, and ward-transfers, arriving ED at nighttime, time spent in ED and nighttime investigations as exposure variables, adjusting for age, GDS and CIRS in the analyses for incident delirium.ResultsWe included 254 patients, mean age 86.1 years (SD 5.2), 49 (19.3%) had incident delirium, 22 with and 27 without hyperactive symptoms. There was a significant association between nighttime investigations and incident delirium in both the unadjusted (odds ratio (OR) 2.22, 95% confidence interval (CI) 1.17 to 4.22, p = 0.015) and the multiadjusted model (OR 2.61, CI 1.26 to 5.40, p = 0.010). There were no associations between any other exposure variables and incident delirium. No exposure variables were associated with delirium motor subtypes.ConclusionsNighttime investigations were associated with incident delirium, even after adjusting for age, cognitive impairment and comorbidity. We cannot out rule that the medical condition leading to nighttime investigations is the true delirium-trigger, so geriatric patients must still receive emergency investigations at nighttime. Hospital environment in broad sense may be a target for delirium prevention.

Possible roles of genetic variations in chemotherapy related cardiotoxicity in pediatric acute lymphoblastic leukemia and osteosarcoma

BackgroundThe treatment of acute lymphoblastic leukemia (ALL) and osteosarcoma (OSC) is very effective: the vast majority of patients recover and survive for decades. However, they still need to face serious adverse effects of chemotherapy. One of these is cardiotoxicity which may lead to progressive heart failure in the long term. Cardiotoxicity is contributed mainly to the use of anthracyclines and might have genetic risk factors. Our goal was to test the association between left ventricular function and genetic variations of candidate genes.MethodsEchocardiography data from medical records of 622 pediatric ALL and 39 OSC patients were collected from the period 1989–2015. Fractional shortening (FS) and ejection fraction (EF) were determined, 70 single nucleotide polymorphisms (SNPs) in 26 genes were genotyped. Multivariate logistic regression and multi-adjusted general linear model were performed to investigate the influence of genetic polymorphisms on the left ventricular parameters. Bayesian network based Bayesian multilevel analysis of relevance (BN-BMLA) method was applied to test for the potential interaction of the studied cofactors and SNPs.ResultsOur results indicate that variations in ABCC2, CYP3A5, NQO1, SLC22A6 and SLC28A3 genes might influence the left ventricular parameters. CYP3A5 rs4646450 TT was 17% among ALL cases with FS lower than 28, and 3% in ALL patients without pathological FS (p = 5.60E-03; OR = 6.94 (1.76–27.39)). SLC28A3 rs7853758 AA was 12% in ALL cases population, while only 1% among controls (p = 6.50E-03; OR = 11.56 (1.98–67.45)). Patients with ABCC2 rs3740066 GG genotype had lower FS during the acute phase of therapy and 5–10 years after treatment (p = 7.38E-03, p = 7.11E-04, respectively). NQO1 rs1043470 rare T allele was associated with lower left ventricular function in the acute phase and 5–10 years after the diagnosis (p = 4.28E-03 and 5.82E-03, respectively), and SLC22A6 gene rs6591722 AA genotype was associated with lower mean FS (p = 1.71E-03), 5–10 years after the diagnosis.ConclusionsGenetic variants in transporters and metabolic enzymes might modulate the individual risk to cardiac toxicity after chemotherapy.

Potential Protective Effect of Osteocalcin in Middle-Aged Men with Erectile Dysfunction: Evidence from the FAMHES Project

In a similar manner to erectile dysfunction (ED), osteocalcin (OC) is also said to be associated with cardiovascular disease (CVD); however, the effect of OC in ED is unclear. This study was conducted based on the Fangchenggang Area Male Health and Examination Survey (FAMHES) project that ran between September and December 2009. ED was evaluated using the International Index of Erectile Function (IIEF-5). OC was shown to be associated with mild (unadjusted: OR = 0.647; P = 0.016) or moderate (unadjusted: OR = 0.453; P = 0.007) ED. Meanwhile, higher OC levels were more prominently associated with ED (unadjusted: OR = 0.702; P = 0.014). When subdividing the groups by age, the correlation between OC and ED presented in those aged 40–49 years, even in the multi-adjusted model, for those with moderate (OR = 0.255, P = 0.044) and severe (OR = 0.065, P = 0.005) ED. The relationship between OC and ED was also associated with a high level of testosterone, non-obesity, drinking, and non-metabolic syndrome. In summary, OC may play a protective role in middle-aged (40–49 years) men with moderate-severe ED, especially those with a high level of testosterone, non-obesity, drinking, and non-metabolic syndrome.

Incidence of diabetic foot ulcer in Japanese patients with type 2 diabetes mellitus: The Fukuoka diabetes registry

AimsAlthough diabetic foot ulcer (DFU) is a serious diabetic complication, there have been no large-scale epidemiological studies of DFU in Japan. We prospectively investigated the incidences of DFU and limb amputation, the risk for developing DFU, and mortality in Japanese patients with type 2 diabetes. MethodsWe followed 4870 participants (mean age, 65 years) with type 2 diabetes attending an outpatient diabetes clinic for a median of 5.3 years (follow-up rate, 97.7%). The primary outcome was the development of DFU. ResultsDuring the follow-up period, DFU occurred in 74 participants (incidence rate, 2.9/1000 person-years) and limb amputation in 12 (incidence rate, 0.47/1000 person-years). DFU recurrence was observed in 21.4% of participants with history of DFU. History of DFU, chronic kidney disease (estimated glomerular filtration rate <60 mL/min/1.73 m2), depressive symptoms, and poor glycemic control were significant risk factors for developing DFU. Survival was significantly lower in participants with DFU and/or history of DFU compared with those without (5-year survival rates: with DFU, 87.7%, without DFU, 95.3%; P < .0001). The hazard ratio for death was 1.80 (95% confidence interval, 1.13–2.73, P = .014) in those with DFU and/or history of DFU in a multi-adjusted model. The most common cause of death was cardiovascular disease among participants with DFU, whereas it was malignant neoplasm among those without. ConclusionsIncidences of DFU and limb amputation were 0.3% and 0.05% per year in this Japanese cohort, respectively. Mortality significantly increased approximately 2-fold in those with DFU and/or history of DFU compared with those without.

Slow-Wave Sleep Is Associated With Incident Hypertension: The Sleep Heart Health Study.

We sought to quantify the association between slow-wave (stage N3) sleep and hypertension in a large cohort of middle-aged men and women. Data from 1850 participants free of baseline hypertension from the Sleep Heart Health Study were analyzed. The primary exposure was percentage of N3 sleep on baseline in-home polysomnography and the primary outcome was incident hypertension, defined as systolic blood pressure ≥ 140 mm Hg, diastolic blood pressure ≥ 90 mm Hg, and/or use of any blood pressure lowering medications at follow-up. Multivariable logistic regression models were adjusted for study site, age, sex, race, waist circumference, tobacco use, alcohol use, apnea-hypopnea index, nocturnal oxygen desaturation, sleep duration, sleep efficiency, and arousal index. Mean age was 59.4 ± 10.1 years and 55.5% were female. The mean baseline systolic and diastolic blood pressure was 118.8 and 70.6 mm Hg, respectively. Approximately 30% of the sample developed hypertension during a mean follow-up of 5.3 years. In the multi-adjusted model, participants in quartiles 1 (<9.8%) and 2 (9.8%-17.7%) of N3 sleep had significantly greater odds of incident hypertension compared with those in quartile 3 (17.7%-25.2%) (OR 1.69, 95% CI 1.21-2.36, p = .002 and OR 1.45, 95% CI 1.04-2.00, p = .03, respectively). No significant effect modification by sex on the N3-hypertension association was observed. In conclusion, compared with intermediate levels of N3 sleep (overlapping the "normal" adult range), lower levels of percent N3 sleep are associated with increased odds of incident hypertension in both men and women, independent of potential confounders, including indices of sleep apnea and sleep fragmentation.

Cardiorespiratory fitness, fatness and incident diabetes.

Increases in prevalence have led to a diabetes pandemic. Obesity and low cardiorespiratory fitness (CRF) are considered to be central mechanisms. We investigated if the effect of CRF on diabetes risk was equivalent across levels of fatness among healthy men. In total 4988 middle-aged Caucasian employed men free of cardiovascular disease, diabetes and cancer were included from the Copenhagen Male Study starting in 1970-71. CRF was assessed using a sub-maximal bicycle ergometer test and body mass index (BMI) was measured by height and weight. Their interaction and stratified associations with diabetes incidence were estimated in multivariable Cox-models including conventional risk factors and social class. Diabetes incidence was assessed through a national register. During 44 years of follow-up, 518 (10.4%) incident cases of diabetes occurred. In the multi-adjusted model, the obese had a significantly higher risk of diabetes compared to normal weight men (Hazard Ratio (HR):4.89; 95% CI: 3.62-6.61) and CRF was significantly inversely associated with diabetes (HR:0.86; 95% CI: 0.75-0.98 per 10-unit increase in ml/kg/min1 CRF). A significant multi-adjusted interaction between CRF, BMI and diabetes was found (p=0.009). The stratified multi-adjusted analyses on BMI showed a significantly stronger reduced risk of diabetes per 10-unit increase in ml/kg/min1 of CRF among the obese (HR:0.58; CI: 0.38-0.89), but a weaker association among overweight (HR:0.86; CI: 0.71-1.03) and normal weight (HR:0.97; CI: 0.76-1.23). High CRF has a stronger protective effect on diabetes among obese than among normal weight men, supporting the recommendation of fitness-enhancing physical activity for preventing diabetes among the obese.

Abstract P350: Lower Urinary Tract Symptoms (LUTS) Predict Incident Cardiovascular Disease (CVD) in a Cohort of Middle-aged to Elderly Men

Introduction: Both lower urinary tract symptoms (LUTS) and cardiovascular disease (CVD) share multiple risk factors. Whether LUTS predict the development of CVD, independent of these factors, remains unclear. Objectives: To examine the cross-sectional and longitudinal relationship between LUTS (total, storage, and voiding LUTS) and first-event CVD. Methods: Participants were drawn from a cohort of randomly-selected, community-dwelling men aged 35-80 years at recruitment (2002-5;n = 1195;sample response rate: 67.8%). LUTS were assessed using the International Prostate Symptom Scale (IPSS). Men with an overall IPSS score &gt;7 were classified as having total LUTS, while men with IPSS scores of &gt;3 for items 2, 4, &amp; 7 and &gt;4 for items 1,3, 5 &amp; 6 were classified with storage and voiding LUTS, respectively. CVD status was obtained by either self-reported physician diagnosis and/or data linkage with a state-wide registry of in-hospital events. The cross-sectional sample (n=1108) consisted of men who had uncomplicated LUTS and complete LUTS measures at baseline. Binomial logistic regression models were used to fit exposure (LUTS) against outcome (CVD) along with qualifying lifestyle, and health-related factors. The longitudinal sample consisted of all CVD-free men at T1 who attended follow-up visits (2007-10;n=701). Cox proportional models were used to determine to hazard ratios (HR) for first-event CVD or date of data-linkage (June 2015). Results: For the cross-sectional sample, 9.4% (n=104) of men examined were found to have CVD. Higher levels of CVD were observed in men with total (35.6% (n=37) vs. 18.2% (n=198) without CVD, p =0.009), storage (40.4% (n=42) vs. 28.3% (n=308), p =0.009) and voiding (31.7% (n=33) vs. 20.0% (n=218), p =0.005) LUTS. In unadjusted binomial models, CVD was associated with total LUTS (OR: 2.38; 95%CI: 1.23-4.31), storage LUTS (1.55;1.08-2.52), and voiding LUTS (1.55;1.08-3.33). In the multi-adjusted model, voiding (1.65; 1.06-3.89) and total (2.18; 1.17-4.11) LUTS was independently associated with CVD, with no significant associations observed for storage LUTS. In the longitudinal analysis (median follow-up duration: 67 months), n=103 CVD cases were detected (14.7% of sample; 20 MI,38 IHD,18 sudden cardiac arrests, and 27 heart failure cases). In unadjusted Cox proportional models, a significant association was detected for voiding (1.28;0.87-1.55) and total (HR: 1.22; 95%CI 1.05-1.83) LUTS, but not storage LUTS (1.18;0.78-2.01). In multi-adjusted models, total LUTS only (2.89;1.37-6.23) were associated with incident CVD. Conclusions: We demonstrate in a group of broadly-representative, middle aged men an independent association between total LUTS at baseline and the development of CVD, suggesting its utility as a prognostic marker for CVD.

Association of Endodontic Lesions with Coronary Artery Disease

An endodontic lesion (EL) is a common manifestation of endodontic infection where Porphyromonas endodontalis is frequently encountered. EL may associate with increased risk for coronary artery disease (CAD) via similar pathways as marginal periodontitis. The aim of this cross-sectional study was to delineate the associations between EL and CAD. Subgingival P. endodontalis, its immune response, and serum lipopolysaccharide were examined as potential mediators between these 2 diseases. The Finnish Parogene study consists of 508 patients (mean age, 62 y) who underwent coronary angiography and extensive clinical and radiographic oral examination. The cardiovascular outcomes included no significant CAD (n = 123), stable CAD (n = 184), and acute coronary syndrome (ACS; n = 169). EL was determined from a panoramic tomography. We combined data of widened periapical spaces (WPSs) and apical rarefactions to a score of EL: 1, no EL (n = 210); 2, ≥1 WPS per 1 apical rarefaction (n = 222); 3, ≥2 apical rarefactions (n = 76). Subgingival P. endodontalis was defined by checkerboard DNA-DNA hybridization analysis, and corresponding serum antibodies were determined by ELISA. In our population, 50.4% had WPSs, and 22.8% apical rarefactions. A total of 51.2% of all teeth with apical rarefactions had received endodontic procedures. Subgingival P. endodontalis levels and serum immunoglobulin G were associated with a higher EL score. In the multiadjusted model (age, sex, smoking, diabetes, body mass index, alveolar bone loss, and number of teeth), having WPSs associated with stable CAD (odds ratio [OR] = 1.94, 95% confidence interval [95% CI] = 1.13 to 3.32, P = 0.016) and highest EL score were associated with ACS (OR = 2.46, 95% CI = 1.09 to 5.54, P = 0.030). This association was especially notable in subjects with untreated teeth with apical rarefactions (n = 59, OR = 2.72, 95% CI = 1.16 to 6.40, P = 0.022). Our findings support the hypothesis that ELs are independently associated with CAD and in particular with ACS. This is of high interest from a public health perspective, considering the high prevalence of ELs and CAD.

The Consequence of Combined Pain and Stress on Work Ability in Female Laboratory Technicians: A Cross-Sectional Study.

Musculoskeletal pain and stress-related disorders are leading causes of impaired work ability, sickness absences and disability pensions. However, knowledge about the combined detrimental effect of pain and stress on work ability is lacking. This study investigates the association between pain in the neck-shoulders, perceived stress, and work ability. In a cross-sectional survey at a large pharmaceutical company in Denmark 473 female laboratory technicians replied to questions about stress (Perceived Stress Scale), musculoskeletal pain intensity (scale 0–10) of the neck and shoulders, and work ability (Work Ability Index). General linear models tested the association between variables. In the multi-adjusted model, stress (p < 0.001) and pain (p < 0.001) had independent main effects on the work ability index score, and there was no significant stress by pain interaction (p = 0.32). Work ability decreased gradually with both increased stress and pain. Workers with low stress and low pain had the highest Work Ability Index score (44.6 (95% CI 43.9–45.3)) and workers with high stress and high pain had the lowest score (32.7 (95% CI 30.6–34.9)). This cross-sectional study indicates that increased stress and musculoskeletal pain are independently associated with lower work ability in female laboratory technicians.
