Abstract
BACKGROUND The association between metabolic syndrome (MetS) and all-cause mortality is well established but it is unclear if there are differences in mortality risk among the 32 possible MetS combinations. Hence, the purpose of this study is to evaluate the associations between different MetS combinations and its individual components with all-cause mortality, and to examine differences in the association by age and sex. METHODS A merged sample of 82,717 adults from 7 U.S. cohorts was used. RESULTS In our sample, MetS was present in 32% of men, 34% of women, 28% of younger adults (18-65 years) and 62% of older adults (>65 years) with 14,989 deaths over 14.6 ± 7.4 years of follow-up. Risk of all-cause mortality was higher in younger individuals with a greater number of MetS factors present, but in older adults having all 5 MetS factors was the only combination significantly associated with mortality. Regardless of age or sex, elevated blood pressure was the MetS factor most consistently present in MetS combinations that were significantly and most strongly associated with mortality. In fact, elevated blood pressure in the absence of other risk factors was significantly associated with mortality in men (HR, 95% CI = 1.56, 1.33-1.84), women (HR = 1.62, 1.44-1.81) and younger adults (HR = 1.61, 1.45-1.79). Conversely, waist circumference, glucose and triglycerides in isolation were not associated with mortality (p>0.05). CONCLUSION In a large U.S. population, different combinations of MetS components vary substantially in their associations with all-cause mortality. Men, women and younger individuals with MetS combinations including elevated blood pressure had stronger associations with greater mortality risk, with minimal associations between MetS and mortality risk in older adults. Thus, we suggest that future algorithms may wish to consider differential weighting of these common metabolic risk factors, particularly in younger populations.

Abstract
BACKGROUND Cardiorespiratory fitness may help to prevent depression and anxiety. A paucity of literature has considered the relationship between cardiorespiratory fitness (CRF) and the incidence of depression and anxiety. The objective of this study was to investigate cross-sectional and longitudinal associations of estimated cardiorespiratory fitness (CRF) with depression and anxiety. METHODS This study included middle-aged and older participants from the second (HUNT 2, 1995-1997) and third (HUNT3, 2006-2008) survery of the Nord-Trøndelag Health Study (HUNT). Baseline non-exercise estimated CRF (eCRF) was determined using standardized algorithms. Depression and anxiety were measured using the Hospital Anxiety and Depression Scale. Logistic regression models were used to evaluate the cross-sectional and longitudinal associations between eCRF and depression and anxiety. RESULTS In cross-sectional adjusted analysis including those who participated in HUNT2 (n = 26,615 mean age 55.7 years), those with medium and high level of eCRF had 21% (OR, 0.79; 95% CI, 0.71-0.89) and 26% (OR, 0.74; 95% CI, 0.66-0.83) lower odds of depression compared to those with low eCRF level, respectively. Longitudinal analysis including those who participated in both HUNT2 and HUNT3 (n = 14,020 mean age 52.2 years) found that medium and level of eCRF was associated with 22% (OR, 0.78; 95% CI, 0.64-0.96) and 19% (OR, 0.81; 95% CI, 0.66-0.99) lower odds of depression compared to those with low eCRF level, respectively. CRF was not associated with anxiety, either cross-sectionally or longitudinally. CONCLUSION Our data suggest that a medium and high level of eCRF during late middle age is cross-sectionally and prospectively associated with lower odds of depression. However, our data do not support that eCRF is associated with anxiety. Further studies are warranted to conclude a causal relationship between eCRF and depression.

Abstract
PURPOSE This study aimed to examine the associations of physical activity and cardiorespiratory fitness (hereafter fitness) with incident glaucoma in a prospective observational study. METHODS Physical activity was measured by self-reported leisure-time activities, and fitness was measured by maximal treadmill test. Incident glaucoma was defined based on physician diagnosis. Participants were 9519 men and women between the ages of 40 and 81 yr old (mean age 50 yr) who were enrolled in the Aerobics Center Longitudinal Study. Hazard ratios (HR) were estimated using Cox proportional hazard regression after adjusting for age, sex, race, examination year, smoking status, heavy alcohol drinking, hypertension, hypercholesterolemia, abnormal ECG, diabetes, cardiovascular disease, and cancer. RESULTS A total of 128 cases of incident glaucoma were reported during a mean follow-up of 5.7 yr. A significantly lower risk of incident glaucoma (HR = 0.53, 95% confidence interval [95% CI] = 0.35-0.79) was found in individuals who met the physical activity guidelines of ≥500 MET·min·wk compared with inactive individuals (0 MET·min·wk). Compared with low fitness (lower third), individuals with high fitness (upper third) also had a significantly lower risk of incident glaucoma (HR = 0.60, 95% CI = 0.38-0.95). A joint analysis of physical activity and fitness showed that meeting physical activity guidelines and being in the high fitness category was associated with the lowest risk for developing glaucoma (HR = 0.49, 95% CI = 0.31-0.79). CONCLUSION These data provide epidemiological evidence that meeting physical activity guidelines or being fit reduces the risk of developing glaucoma.

Abstract
Background Hyperhomocysteinemia (HHcy) is the risk factor for cardiovascular disease and stroke. However, the impacts on the genetic variation of methylene tetrahydrofolate reductase (MTHFR) on plasma homocysteine levels in the Northeast Chinese population have not been studied. Therefore, this study was carried out to determine the relationship between HHcy and MTHFR gene variation, and whether it was influenced by age and sex of the population in Northeast China. Materials and Methods A total of 466 subjects were randomly enrolled in this study. According to the homocysteine levels (Hcy ≥ 15 μmol/L) of the subjects, they were divided into hyperhomocysteine (HHcy = 206) and normal homocysteine (Hcy = 260). Polymerase chain reaction/high-resolution dissolution curve and homocysteine determination kit methods were used for genotype testing and homocysteine detection, respectively. Results High plasma homocysteine levels are associated with MTHFR 677T and 1298A [P < 0.00, odds ratio (confidence interval) = 1.842 (1.418-2.394) >1], which is related to increasing age (Prange = 0.0005-0.0161), with the homocysteine levels of males higher than females (P < 0.0001). Conclusion High plasma homocysteine levels were linked to the MTHFR gene mutation. In addition, plasma homocysteine levels increased significantly with age with male's homocysteine levels higher than that of females.

Abstract
OBJECTIVE To examine the association between muscular strength and incident type 2 diabetes, independent of cardiorespiratory fitness (CRF). PATIENTS AND METHODS A total of 4681 adults aged 20 to 100 years who had no type 2 diabetes at baseline were included in the current prospective cohort study. Participants underwent muscular strength tests and maximal treadmill exercise tests between January 1, 1981, and December 31, 2006. Muscular strength was measured by leg and bench press and categorized as age group- and sex-specific thirds (lower, middle, and upper) of the combined strength score. Type 2 diabetes was defined on the basis of fasting plasma glucose levels, insulin therapy, or physician diagnoses. RESULTS During a mean follow-up of 8.3 years, 229 of the 4681 patients (4.9%) had development of type 2 diabetes. Participants with the middle level of muscular strength had a 32% lower risk of development of type 2 diabetes (hazard ratio, 0.68; 95% confidence interval, 0.49-0.94; P=.02) compared with those with the lower level of muscular strength after adjusting for potential confounders, including estimated CRF. However, no significant association between the upper level of muscular strength and incident type 2 diabetes was observed. CONCLUSION A moderate level of muscular strength is associated with a lower risk of type 2 diabetes, independent of estimated CRF. More studies on the dose-response relationship between muscular strength and type 2 diabetes are needed.

Abstract
This study was aimed to investigate whether interferon (IFN)-induced protein 35 (IFI35) affects the signaling pathway of nuclear factor-kappa B (NF-κB) and to observe the effect of different expressions of IFI35 on the proliferation of endothelial cells and angiogenesis in rats with acute cerebral infarction. A suture method was adopted to prepare a mouse model of permanent middle cerebral artery occlusion (PMCAO). After the treatment of cerebral artery occlusion in 200 healthy male mice (weighting 20g-40g), 47 mice were selected and the double luciferase assay was used to identify different structural domains of IFI35; for the remaining 153 mice, RT-PCR and immunohistochemical assays were used to detect the mRNA expression of glioma-associated oncogene homolog 1 (Gli1), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and CD105 (endoglin). The results showed that IFI35 could reduce the level of p65 protein (REL-A) in the nucleus while affecting the production of p-p65 in the cytoplasm. At the same time, IFI35 could be used in combination with a NID1 protein domain + Nmi protein to inhibit the signaling pathway of NF-κB. Expressions of Gli1, VEGF, bFGF, and CD105 in the IFI35 treatment group were all significantly reduced (P less than0.05). In conclusion, IFI35 could suppress the activation of the NF-κB signaling pathway, reduce the proliferating potential of vascular endothelial cells, and lower the expression of vascular growth factors, thereby inhibiting angiogenesis in mice with acute cerebral infarction.

Abstract
AIM To evaluate the clinical usefulness of quantitative dual-energy (DE) computed tomography (CT) iodine enhancement metrics combined with morphological CT features in distinguishing small-cell lung cancer (SCLC) from non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS One hundred and six untreated lung cancer patients who underwent DECT before biopsy or surgery were prospectively enrolled. Twenty-seven routine CT descriptors, including tumour location, size, shape, margin, enhancement heterogeneity, and internal and surrounding structures, and associated findings were assessed and DECT parameters were measured in all patients. Multiple logistic regression analyses were applied to identify independent predictors of SCLC. The area under the receiver operating characteristic curve was compared between CT features combined with DECT metrics and CT features alone for distinguishing SCLC from NSCLC. RESULTS Histology revealed NSCLC in 80 and SCLC in 26 patients. In univariate analysis, 12 morphological CT features and two DECT metrics differed significantly between NSCLC and SCLC. When DECT parameters were combined with CT features for multivariate analysis, the independent predictors of SCLC were large tumour size, central location, confluent mediastinal lymphadenopathy, homogeneous enhancement, absence of coarse spiculation, and lower iodine density and iodine ratio (all p<0.05). The area under the receiver operating characteristic curve was improved from 0.908 to 0.981 after adding DECT metrics compared with CT features alone (p=0.007). CONCLUSION The combination of DECT measures and CT morphological features can be used to distinguish SCLC from NSCLC, with higher diagnostic performance compared with CT morphological features alone.

Abstract
Objective/Background: Exercise training has been demonstrated to beneficially influence mean-level measures of sleep; however, few studies have examined the impact of an exercise intervention on night-to-night variability in sleep. This study investigated whether four months of moderate-intensity exercise impacted night-to-night variability in sleep among older women. Methods: Participants (n = 49) were randomized to one of two moderate-intensity walking programs with different doses of energy expenditure: low-dose (n = 23: 8 kcal/kg of body weight per week) or high-dose (n = 26: 14 kcal/kg of body weight per week). Sleep parameters were assessed objectively via actigraphy at baseline, mid- (2 months), and postintervention (4 months). Nightly variability in each of the sleep parameters was calculated using the seven-day standard deviation (SD) and a coefficient of variation (SD/mean x 100%). Cardiorespiratory fitness (VO2peak) was measured at baseline and postintervention using a graded treadmill test. Results: Both measures of nightly variability demonstrated a borderline to significantly lower amount of night-to-night variability in wake time after sleep onset (WASO) and number of awakenings at postintervention in comparison to baseline (p ≤ 0.05). Higher VO2peak levels at baseline were associated with less time in bed and lower total sleep time variability throughout the exercise intervention (p < 0.05). Conclusion: Overall, participation in moderate-intensity exercise was observed to reduce the amount of nightly variability for WASO and number of awakenings over time in older women.

Abstract
BACKGROUND AND PURPOSE Although several studies have assessed the importance of traditional risk factors in predicting stroke, none have concurrently addressed the stroke-predicting ability of these risk factors across the lifespan of subjects without a hypertension (HTN) diagnosis. Thus, this study aimed to assess the importance of blood-pressure-related risk indicators, cardiorespiratory fitness (CRF), weight status, diabetes mellitus (DM), and lifestyle factors as predictors of stroke in different stages of life among non-hypertensive subjects. MATERIALS AND METHODS This study was a long-term follow-up study including 33,254 men and 10,598 women from the Aerobics Center Longitudinal Study (ACLS) who were 18-100 years old and did not have a HTN diagnosis at baseline. Logistic regression models were constructed using forward selection procedures for each age category, with stroke occurrence as the dependent variable, and pulse pressure (PP), mean arterial pressure (MAP), systolic blood pressure (SBP), smoking status, CRF, drinking behavior, DM status, and weight status as potential predictors. RESULTS In total, 507 subjects had a stroke during an average follow-up period of 17 years (range=1-34 years). Logistic regression models showed that MAP values (P=0.043) in those aged 19-39 years; SBP (P<0.001), CRF (P=0.001), weight status (P=0.005), and alcohol consumption (P=0.001) in those 40-60 years old; and CRF (P=0.002), weight status (P=0.005), and DM status (P=0.037) in those over 60 years old were predictors of stroke. CONCLUSION These findings suggest that, among individuals without a baseline HTN diagnosis, classic modifiable risk factors for stroke change across different stages of life.

Abstract
Studies have examined mortality risk for metabolically healthy obesity, defined as zero or one metabolic risk factors but not as zero risk factors. Thus, we sought to determine the independent mortality risk associated with obesity or elevated glucose, blood pressure or lipids in isolation or clustered together. The sample included 54 089 men and women from five cohort studies (follow-up = 12.8 ± 7.2 years and 4864 [9.0%] deaths). Individuals were categorized as having obesity or elevated glucose, blood pressure or lipids alone or clustered with obesity or another metabolic factor. In our study sample, 6% of individuals presented with obesity but no other metabolic abnormalities. General obesity (hazard ratios [HR], 95% CI = 1.10, 0.8-1.6) and abdominal obesity (HR = 1.24, 0.9-1.7) in the absence of metabolic risk factors were not associated with mortality risk compared to lean individuals. Conversely, diabetes, hypertension and dyslipidaemia in isolation were significantly associated with mortality risk (HR range = 1.17-1.94, P < 0.05). However, when using traditional approaches, obesity (HR = 1.12, 1.02-1.23) is independently associated with mortality risk after statistical adjustment for the other metabolic risk factors. Similarly, metabolically healthy obesity, when defined as zero or one risk factor, is also associated with increased mortality risk (HR = 1.15, 1.01-1.32) as compared to lean healthy individuals. Obesity in the absence of metabolic abnormalities may not be associated with higher risk for all-cause mortality compared to lean healthy individuals. Conversely, elevation of even a single metabolic risk factor is associated with increased mortality risk.

Abstract
Abstract
Background
Sedentary behaviour (SB) may contribute to the development of several chronic diseases, such as hypertension, diabetes mellitus (DM) and all-cause mortality. The aim of this study is to investigate the association between different domains of SB with diabetes among adult users of the Brazilian National Health System (NHS).
Methods
Cross-sectional study from the primary care system of the Brazilian NHS in the city of Bauru, Brazil. SB, physical activity (PA), DM and other chronic diseases were assessed by face-to-face interviews and medical records. As potential confounders in the adjusted model, we used gender, age, economic status, smoking status, hypertension, hypercholesterolaemia and PA.
Results
The study was composed of 147 men and 410 women. The fully adjusted model showed that Brazilian adults spending ≥3 h per day in television viewing (OR = 1.61 [95% CI: 1.11–2.33]) and overall SB (OR = 1.60 [95% CI: 1.09–2.36]) had increased prevalence of DM compared to those spending <3 h per day.
Conclusions
TV viewing and overall SB was associated with higher prevalence of DM in Brazilian adults from the NHS, even after controlling for potential confounders including PA.

Abstract
Prenatal physical activity (PA) reduces the risk of delivering infants with a birthweight ≥4000 g among normal-weight pregnant women, but evidence on the impact of maternal cardiorespiratory fitness (CRF) on birthweight remains equivocal among overweight or obese (OW/OB) pregnant women. The purpose of this study was to evaluate the relationship between maternal prenatal PA and CRF and birthweight in OW/OB pregnant women. Data from a randomized controlled exercise intervention trial in sedentary, OW/OB pregnant women were used. Women with complete data (n = 89) on birthweight, peak oxygen consumption (at 17 weeks), and daily PA were selected for analyses. Multiple linear regression models were performed to determine the independent and joint associations of maternal PA and CRF with birthweight while adjusting for gestational age, weight gain, and group allocation. On average, participants were 32 years old, OW/OB (BMI 29.97 ± 7.14 kg/m2), unfit (VO2peak: 19.85 ± 3.35 ml O2 kg-1 min-1), and led low active lifestyles (6579.91 ± 2379.17 steps/day). Analyses showed that maternal PA (steps·day-1·month-1) (β = 0.03 g, 95% CI: -0.03, 0.08 g) and CRF (ml O2·kg-1·min-1) (β = -8.8 g, 95%CI: -42.2, 24.5 g) were neither independently nor jointly (β = 0.006 g, 95%CI: -0.005, 0.02 g) associated with birthweight. Maternal PA and CRF during pregnancy were not related to birthweight in OW/OB pregnant women. The limited variability in maternal PA and CRF and low dose of PA may explain the null findings of this study. Given the paucity of studies examining these relationships in OW/OB pregnant women, more research is warranted.

Abstract
OBJECTIVE To assess the independent and combined associations of long-term changes in depressive symptoms (DSs) and estimated cardiorespiratory fitness (eCRF) with all-cause mortality. PARTICIPANTS AND METHODS This is a longitudinal cohort study of 15,217 middle-aged and older individuals attending both the second (from August 15, 1995, through June 18, 1997) and third (from October 3, 2006, through June 25, 2008) health surveys of the Nord-Trøndelag Health Study, Norway, and followed until December 31, 2014. Depressive symptoms were estimated using the validated Hospital Anxiety and Depression Scale, and a validated nonexercise model estimated eCRF. Hazard ratios (HRs) were computed using Cox regression. All-cause mortality was ascertained using the Norwegian Cause of Death Registry. RESULTS The mean age was 63.3±8.9 years, and 7932 (52.1%) were women. During the follow-up period of 7.1±1.1 years, 1157 participants (7.6%) died. Multivariable-adjusted analyses revealed that persistently low DSs were independently associated with a 28% risk reduction of all-cause mortality (HR, 0.72; 95% CI, 0.56-0.92; P=.008) as compared with persistently high DSs. Persistently high eCRF independently predicted a 26% lower risk of death (HR, 0.76; 95% CI, 0.66-0.88; P<.001) relative to low eCRF. Analyses of changes in DSs and eCRF revealed that persistently high eCRF combined with decreased or persistently low DSs decreased mortality risk by 49% (HR, 0.51; 95% CI, 0.28-0.91; P=.02) and 47% (HR, 0.53; 95% CI, 0.37-0.76, P=.001), respectively. CONCLUSION Maintaining low DSs and high eCRF was independently associated with a lower risk of all-cause mortality. The lowest mortality risk was observed for persistently high eCRF combined with decreased or persistently low DSs. These results emphasize the effect of preventing DSs and maintaining high CRF on long-term mortality risk, which is potentially important for long-term population health.

J Sci Med Sport 2018; 22:186-190.

Abstract
OBJECTIVES Maternal body mass index (BMI) is a significant determinant of infant macrosomia. Given the strong metabolic effects of physical activity (PA), independent of body mass, it is unclear as to whether maternal PA may affect the risk of delivering a macrosomic infant. Thus, the purpose of this study was to determine if maternal PA moderates the relationship between maternal BMI and infant macrosomia. DESIGN Cross-sectional study using data from the National Maternal and Infant Health Survey (1988). METHODS Women with singleton pregnancies, delivering term (37-44 weeks), live-birth infants (n=6390) were included in the analyses. Multiple logistic regression models were performed to determine the moderating effects of maternal self-reported PA in the preconception and prenatal periods on the risk of infant macrosomia after adjusting for maternal age, race/ethnicity, gestational age and weight gain, smoking and alcohol use, and infant sex. RESULTS Mothers were on average 25 years of age and nearly 25% were overweight or obese. Prevalence of macrosomia was 9%. Overweight or obese women had increased odds of delivering a macrosomic infant (OR=1.69, p<0.0001; OR=1.67, p=0.0032, respectively). Nearly 50% and 42% of mothers reported participating in at least 30min of moderate PA, three times per week in the preconception and prenatal periods, respectively. Neither maternal PA in the preconception (OR=0.98, p=0.34) nor prenatal (OR=1.00, p=0.13) periods moderated the association between maternal BMI and infant macrosomia. CONCLUSIONS Maternal BMI was a significant predictor of infant macrosomia. However, mothers participating in at least 90min of PA per week in the preconception or prenatal periods did not moderate this association. More rigorous study designs and precise measurements of maternal PA and neonatal size are warranted.

Role of Physical Activity and Fitness in the Characterization and Prognosis of the Metabolically Healthy Obesity Phenotype: A Systematic Review and Meta-analysis. Prog Cardiovasc Dis 2018; 61:190-205.

Abstract
The aims of the present article are to systematically review and meta-analyze the existing evidence on: 1) differences in physical activity (PA), sedentary behavior (SB), cardiorespiratory fitness (CRF) and muscular strength (MST) between metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO); and 2) the prognosis of all-cause mortality and cardiovascular disease (CVD) mortality/morbidity in MHO individuals, compared with the best scenario possible, i.e., metabolically healthy normal-weight (MHNW), after adjusting for PA, SB, CRF or MST. Our systematic review identified 67 cross-sectional studies to address aim 1, and 11 longitudinal studies to address aim 2. The major findings and conclusions from the current meta-analysis are: 1) MHO individuals are more active, spend less time in SB, and have a higher level of CRF (yet no differences in MST) than MUO individuals, suggesting that their healthier metabolic profile could be at least partially due to these healthier lifestyle factors and attributes. 2) The meta-analysis of cohort studies which accounted for PA (N = 10 unique cohorts, 100% scored as high-quality) support the notion that MHO individuals have a 24-33% higher risk of all-cause mortality and CVD mortality/morbidity compared to MHNW individuals. This risk was borderline significant/non-significant, independent of the length of the follow-up and lower than that reported in previous meta-analyses in this topic including all type of studies, which could be indicating a modest reduction in the risk estimates as a consequence of accounting for PA. 3) Only one study has examined the role of CRF in the prognosis of MHO individuals. This study suggests that the differences in the risk of all-cause mortality and CVD mortality/morbidity between MHO and MHNW are largely explained by differences in CRF between these two phenotypes.

Abstract
OBJECTIVE To examine the relationship between estimated cardiorespiratory fitness (eCRF) using nonexercise equations and all-cancer mortality in a representative sample of the US population. PARTICIPANTS AND METHODS A total of 8506 study participants were derived from the Third National Health and Nutrition Examination Survey, conducted from October 18, 1988, to October 15, 1994. They were followed for all-cancer mortality. Participants' CRF was estimated from nonexercise models that were determined by age, body mass index, waist circumference, resting heart rate, physical activity status, and smoking status, and further grouped into quintiles. Hazard ratios (HRs) and 95% CIs were calculated from Cox proportional hazards models for the relationship between eCRF and all-cancer mortality. RESULTS During a mean of 19.5 years of follow-up, 455 cancer deaths (263 men and 192 women) were registered. After adjustment for race/ethnicity, age, educational level, current smoking, hypertension, diabetes mellitus, and hypercholesterolemia, each 1-metabolic equivalent increase in eCRF was associated with 30% (95% CI, 24%-35%) and 27% (95% CI, 18%-36%) risk reduction for all-cancer mortality in men and women, respectively. When eCRF was categorized into quintiles, HRs (95% CIs) were 0.47 (0.24-0.95), 0.81 (0.46-1.44), 0.49 (0.26-0.93), and 0.57 (0.31-1.06) across incremental quintiles in women (quintile 1 was the reference group). However, none of the HRs reached statistical significance in men. CONCLUSION The eCRF was inversely associated with all-cancer mortality in quintiles 2 and 4 in women. More research is needed to further understand the association between eCRF and all-cancer mortality in men.
