- AIM: We investigated the association between low Apgar score, other perinatal characteristics and low stress resilience in adolescence. A within-siblings analysis was used to tackle unmeasured shared familial confounding.METHODS: We used a national cohort of 527,763 males born in Sweden between 1973 and 1992 who undertook military conscription assessments at mean age 18 years (17-20). Conscription examinations included a measure of stress resilience. Information on Apgar score and other perinatal characteristics was obtained through linkage with the Medical Birth Register. Analyses were conducted using ordinary least squares and fixed-effects linear regression models adjusted for potential confounding factors.RESULTS: Infants with a prolonged low Apgar score at five minutes had an increased risk of low stress resilience in adolescence compared to those with highest scores at one minute, with an adjusted coefficient and 95% confidence interval of -0.26 (-0.39, -0.13). The associations were no longer statistically significant when using within-siblings models. However, the associations with stress resilience and birthweight remained statistically significant in all analyses.CONCLUSION: The association with low Apgar score seems to be explained by confounding due to shared childhood circumstances among siblings from the same family, while low birthweight is independently associated with low stress resilience.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: A large proportion of cancer survivors are of working age, and maintaining health is of interest both for their working and private life. However, patterns and determinants of comorbidity over time among adult cancer survivors are incompletely described. We aimed to identify distinct comorbidity trajectories and their potential determinants.METHODS: In a cohort study of Swedish men born between 1952 and 1956, men diagnosed with cancer between 2000 and 2003 (n=878) were matched with cancer-free men (n=4340) and followed over five years after their first year of survival. Comorbid diseases were identified using hospital diagnoses and included in the analysis using group-based trajectory modelling. The association of socioeconomic and developmental characteristics were assessed using multinomial logit models.RESULTS: Four distinct comorbidity trajectories were identified. As many as 84% of cancer survivors remained at very low levels of comorbidity, and the distribution of trajectories was similar among the cancer survivors and the cancer-free men. Increases in comorbidity were seen among those who had comorbid disease at baseline and among those with poor summary disease scores in adolescence. Socioeconomic characteristics and physical, cognitive and psychological function were associated with types of trajectory in unadjusted models but did not retain independent relationships with them after simultaneous adjustment.CONCLUSIONS: Among working-age male cancer survivors, the majority remained free or had very low levels of comorbidity. Those with poorer health in adolescence and pre-existing comorbid diseases at cancer diagnosis may, however, benefit from follow-up to prevent further increases in comorbidity.

Sex of older siblings and cognitive function
- 2017
-
Konferensbidrag (refereegranskat)abstract
- Background : Number of older siblings is associated with lower cognitive function, possibly as marker of material disadvantage. Sex differences may signal an influence of inter-sibling interactions.Methods: The study used a national Swedish register-based cohort of men (n=644,603), born between 1970 and 1992 who undertook military conscription assessments in adolescence that included cognitive function measured on a normally-distributed scale of 1-9. Associations with siblings were investigated using linear regression.Results: After adjustment for numbers of younger siblings, year of conscription assessment, age/year of birth, sex, European socioeconomic classification for parents and maternal age at delivery; the regression coefficients (and 95% confidence intervals) for cognitive function are -0.26 (-0.27, -0.25), -0.42 (-0.44, -0.40), and -0.72 (-0.76, -0.67) for one, two and three or more male older siblings, respectively, compared with none; and -0.22 (-0.23, -0.21), -0.39 (-.41, -0.37), -0.62 (-0.67, -0.58) for one two and three or more female older siblings, respectively, compared with none. A larger number of younger siblings is not associated with lower cognitive function in the adjusted model.Conclusions: Family size is associated with cognitive function: older male siblings may have greater implications than females due to their demands on familial resources or through inter-sibling interactions.

- The aim was to investigate whether older siblings are associated with development of stress resilience in adolescence and if there are differences by sex of siblings. The study used a Swedish register-based cohort of men (n=664 603) born between 1970 and 1992 who undertook military conscription assessments in adolescence that included a measure of stress resilience: associations were assessed using multinomial logistic regression. Adjusted relative risk ratios (95% confidence intervals) for low stress resilience (n=136 746) compared with high (n=142 581) are 1.33 (1.30, 1.35), 1.65 (1.59, 1.71) and 2.36 (2.18, 2.54) for one, two and three or more male older siblings, compared with none. Equivalent values for female older siblings do not have overlapping confidence intervals with males and are 1.19 (1.17, 1.21), 1.46 (1.40, 1.51) and 1.87 (1.73, 2.03). When the individual male and female siblings are compared directly (one male sibling compared with one female sibling, etc.) and after adjustment, including for cognitive function, there is a statistically significant (p<0.005) greater risk for low stress resilience associated with male siblings. Older male siblings may have greater adverse implications for psychological development, perhaps due to greater demands on familial resources or inter-sibling interactions.

Tidskriftsartikel (refereegranskat)abstract
- Vaccinium myrtillus, have a high content of phenolic compounds including anthocyanins, which could provide cardiometabolic health benefits following acute myocardial infarction (AMI). We hypothesized that standard medical therapy supplemented with freeze-dried bilberry after AMI would have a more beneficial effect on cardiovascular risk markers and exercise capacity than medical therapy alone. Patients were allocated in a 1:1 ratio within 24 hours of percutaneous coronary intervention in an 8- week trial either to V myrtillus powder (40 g/d, equivalent to 480 g fresh bilberries) and standard medical therapy or to a control group receiving standard medical therapy alone. High-sensitivity C-reactive protein and exercise capacity measured with the 6-minute walk test were the primary biochemical and clinical end points, respectively. Fifty subjects completed the study. No statistically significant difference in high-sensitivity C-reactive protein was detected between groups. The mean 6-minute walk test distance increased significantly more in the bilberry group compared to the control group: mean difference 38 m at follow-up (95% confidence interval 14- 62, P =.003). Ex vivo oxidized low-density lipoprotein was significantly lowered in the bilberry group compared to control, geometric mean ratio 0.80 (95% confidence interval 0.66-0.96, P =.017), whereas total cholesterol and low-density lipoprotein cholesterol did not differ significantly between groups. Anthocyanin-derived metabolites in blood increased significantly in the bilberry group during the intervention and were different after 8 weeks between the bilberry group and control. Findings in the present study suggest that bilberries may have clinically relevant beneficial effects following AMI; a larger, double-blind clinical trial is warranted to confirm this.

Tidskriftsartikel (refereegranskat)abstract
- Background and purpose: Physical and psychological characteristics in adolescence are associated with subsequent stroke risk. Our aim is to investigate their relevance to length of hospital stay and risk of second stroke.Methods: Swedish men born between 1952 and 1956 (n=237 879) were followed from 1987 to 2010 using information from population-based national registers. Stress resilience, body mass index, cognitive function, physical fitness, and blood pressure were measured at compulsory military conscription examinations in late adolescence. Joint Cox proportional hazards models estimated the associations of these characteristics with long compared with short duration of stroke-related hospital stay and with second stroke compared with first.Results: Some 3000 men were diagnosed with nonfatal stroke between ages 31 and 58 years. Low stress resilience, underweight, and higher systolic blood pressure (per 1-mm Hg increase) during adolescence were associated with longer hospital stay (compared with shorter) in ischemic stroke, with adjusted relative hazard ratios (and 95% confidence intervals) of 1.46 (1.08-1.89), 1.41 (1.04-1.91), and 1.01 (1.00-1.02), respectively. Elevated systolic and diastolic blood pressures during adolescence were associated with longer hospital stay in men with intracerebral hemorrhage: 1.01 (1.00-1.03) and 1.02 (1.00-1.04), respectively. Among both stroke types, obesity in adolescence conferred an increased risk of second stroke: 2.06 (1.21-3.45).Conclusions: Some characteristics relevant to length of stroke-related hospital stay and risk of second stroke are already present in adolescence. Early lifestyle influences are of importance not only to stroke risk by middle age but also to recurrence and use of healthcare resources among stroke survivors.

Tidskriftsartikel (refereegranskat)abstract
- Background: Bilberries from Sweden, rich in polyphenols, have shown cholesterol-lowering effects in small studies, and the cholesterol-lowering properties of oats, with abundant beta-glucans and potentially bioactive phytochemicals, are well established. Both may provide cardiometabolic benefits following acute myocardial infarction (AMI), but large studies of adequate statistical power and appropriate duration are needed to confirm clinically relevant treatment effects. No previous study has evaluated the potential additive or synergistic effects of bilberry combined with oats on cardiometabolic risk factors. Our primary objective is to assess cardioprotective effects of diet supplementation with dried bilberry or with bioprocessed oat bran, with a secondary explorative objective of assessing their combination, compared with a neutral isocaloric reference supplement, initiated within 5 days following percutaneous coronary intervention (PCI) for AMI. Methods: The effects of Bilberry and Oat intake on lipids, inflammation and exercise capacity after Acute Myocardial Infarction (BIOAMI) trial is a double-blind, randomized, placebo-controlled clinical trial. A total of 900 patients will be randomized post-PCI to one of four dietary intervention arms. After randomization, subjects will receive beverages with bilberry powder (active), beverages with high-fiber bioprocessed oat bran (active), beverages with bilberry and oats combined (active), or reference beverages containing no active bilberry or active oats, for consumption twice daily during a 3-month intervention. The primary endpoint is the difference in LDL cholesterol change between the intervention groups after 3 months. The major secondary endpoint is exercise capacity at 3 months. Other secondary endpoints include plasma concentrations of biochemical markers of inflammation, metabolomics, and gut microbiota composition after 3 months. Discussion: Controlling hyperlipidemia and inflammation is critical to preventing new cardiovascular events, but novel pharmacological treatments for these conditions are expensive and associated with negative side effects. If bilberry and/or oat, in addition to standard medical therapy, can lower LDL cholesterol and inflammation more than standard therapy alone, this could be a cost-effective and safe dietary strategy for secondary prevention after AMI.

- Background. The study aimed to investigate patient and spouse perception of cognitive functioning 1 to 2 years after coronary artery bypass grafting.Methods. Seventy-six married patients who had undergone coronary artery bypass grafting were selected and sex- and age-matched with 75 concurrent married patients who had undergone percutaneous transluminal coronary angioplasty. Couples received a letter of explanation and then completed telephone interviews. Forty-seven questions assessed memory, concentration, general health, social functioning, and emotional state. Response choices were: improved, unchanged, or deteriorated function after coronary artery bypass grafting/percutaneous transluminal coronary angioplasty.Results. Patients who had undergone coronary artery bypass grafting did not differ in subjective ratings on any measure from patients who had undergone percutaneous transluminal coronary angioplasty. There were no differences between spouses in the respective groups; spouse ratings also did not differ from patient ratings. Only in memory function did patients and spouses report a postprocedural decline.Conclusions. No subjective differences were found in patients who had undergone either coronary artery bypass grafting or percutaneous transluminal coronary angioplasty. Spouse ratings agreed with each other and with patient ratings. Positive correlations were found between the questionnaire factors, suggesting that perceived health and well-being are associated with subjective cognition.

Life-course influences on occurrence and outcome for stroke and coronary heart disease
- 2017

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Although typical clinical onset does not occur until adulthood, cardiovascular disease (CVD) may have a long natural history with accumulation of risks beginning in early life and continuing through childhood and into adolescence and adulthood. Therefore, it is important to adopt a life-course approach to explore accumulation of risks, as well as identifying age-defined windows of susceptibility, from early life to disease onset. This thesis examines characteristics in adolescence and adulthood linked with subsequent risk of CVD. One area is concerned with physical and psychological characteristics in adolescence, which reflects inherited and acquired elements from childhood, and their association with occurrence and outcome of subsequent stroke and coronary heart disease many years later. The second area focuses on severe infections and subsequent delayed risk of CVD. Data from several Swedish registers were used to provide information on a general population-based cohort of men. Some 284 198 males, born in Sweden from 1952 to 1956 and included in the Swedish Military Conscription Register, form the basis of the study cohort for this thesis. Our results indicate that characteristics already present in adolescence may have an important role in determining long-term cardiovascular health. Stress resilience in adolescence was associated with an increased risk of stroke and CHD, working in part through other CVD factors, in particular physical fitness. Stress resilience, unhealthy BMI and elevated blood pressure in adolescence were also associated with aspects of stroke severity among survivors of a first stroke. We demonstrated an association for severe infections (hospital admission for sepsis and pneumonia) in adulthood with subsequent delayed risk of CVD, independent of risk factors from adolescence. Persistent systemic inflammatory activity which could follow infection, and that might persist long after infections resolve, represents a possible mechanism. Interventions to protect against CVD should begin by adolescence; and there may be a period of heightened susceptibility in the years following severe infection when additional monitoring and interventions for CVD may be of value.

- Background/Purpose: Recent studies show that early life stress is associated with later risk of cardiovascular disease (CVD) and stress may also increase the risk of psychiatric disease. We investigated the association between non-psychotic mental disorders in adolescence and subsequent myocardial infarction, and the role of stress resilience and physical fitness in this association.Method: This is a register-based cohort study with 238 013 males born between 1952 and 1956 followed from 1987 to 2010 using information from Swedish registers. Stress resilience was measured at a compulsory military conscription examination using a semi-structured interview with a psychologist. Physical fitness was measured at conscription examination with a cycle ergometer test. A total of 34 503 men were diagnosed with a non-psychotic mental disorder at conscription. Using Cox regression, we estimated the association of mental disorders with myocardial infarction after adjustment for other established CVD risk factors in adolescence. Stress resilience and physical fitness were included in the adjusted model in a second set of analyses.Results: A total of 5891 diagnoses of first myocardial infarction were identified. Non-psychotic mental disorders were associated with an increased risk of myocardial infarction, with a hazard ratio (HR) and confidence interval (CI) of 1.51 (1.41–1.62). The association remained statistically significant after adjustment for other important potential confounders in adolescence such as systolic and diastolic blood pressure, body mass index, inflammation, cognitive function, parental socioeconomic index and a summary disease score (HR 1.24 (CI 1.13–1.35)). The association was further explained by stress resilience and lifestyle factors assessed with a cardiovascular fitness test in adolescence, as the association attenuated but remained statistically significant when further adjusting for stress resilience and physical fitness (HR 1.18 (CI 1.08–1.29)).Conclusion: A non-psychotic mental disorder in adolescences may increase the risk of developing myocardial infarction later in life. This association was partly but not completely explained by poorer stress resilience and physical fitness. Effective prevention might focus on behaviour/lifestyle and psychosocial stress in early life.

- Background: Severe infections in adulthood are associated with subsequent short-term cardiovascular disease. Whether hospital admission for sepsis or pneumonia is associated with persistent increased risk (over a year after infection) is less well established.Design: The design of this study was as a register-based cohort study.Methods: Some 236,739 men born between 1952-1956 were followed from conscription assessments in adolescence to 2010. All-cause cardiovascular disease ( n = 46,754), including coronary heart disease ( n = 10,279) and stroke ( n = 3438), was identified through national registers 1970-2010 (at ages 18-58 years).Results: Sepsis or pneumonia in adulthood (resulting in hospital admission) are associated with increased risk of cardiovascular disease in the years following infection. The risk is highest during the first year after the infection, with an adjusted hazard ratio (and 95% confidence intervals) of 6.33 (5.65-7.09) and a notably increased risk persisted with hazard ratios of 2.47 (2.04-3.00) for the second and 2.12 (1.71-2.62) for the third year after infection. The risk attenuated with time, but remained raised for at least five years after infection; 1.87 (1.47-2.38). The results are adjusted for characteristics in childhood, cardiovascular risk factors and medical history in adolescence. Similar statistically significant associations were found for coronary heart disease and stroke.Conclusions: Raised risks of cardiovascular disease following hospital admission for sepsis or pneumonia were increased for more than five years after the infection, but with the highest magnitude during the first three years following infection, suggesting a period of vulnerability when health professionals and patients should be aware of the heightened risk for cardiovascular disease.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: Psychosocial stress is a suggested risk for coronary heart disease (CHD). The relationship of stress resilience in adolescence with subsequent CHD risk is underinvestigated, so our objective was to assess this and investigate the possible mediating role of physical fitness.METHODS: In this register-based study, 237 980 men born between 1952 and 1956 were followed from 1987 to 2010 using information from Swedish registers. Stress resilience was measured at a compulsory military conscription examination using a semistructured interview with a psychologist. Some 10 581 diagnoses of CHD were identified. Cox regression estimated the association of stress resilience with CHD, with adjustment for established cardiovascular risk factors.RESULTS: Low-stress resilience was associated with increased CHD risk. The association remained after adjustment for physical fitness and other potential confounding and mediating factors, with adjusted HRs (and 95% CIs) of 1.17 (1.10 to 1.25), with some evidence of mediation by physical fitness. CHD incidence rates per 1000 person-years (and 95% CIs) for low-stress, medium-stress and high-stress resilience were 2.61 (2.52 to 2.70), 1.97 (1.92 to 2.03) and 1.59 (1.53 to 1.67) respectively. Higher physical fitness was inversely associated with CHD risk; however, this was attenuated by low-stress resilience, shown by interaction testing (p<0.001).CONCLUSIONS: Low-stress resilience in adolescence was associated with increased risk of CHD in middle age and may diminish the benefit of physical fitness. This represents new evidence of the role of stress resilience in determining risk of CHD and its interrelationship with physical fitness.

- Objective Exposure to psychosocial stress has been identified as a possible stroke risk, but the role of stress resilience which may be relevant to chronic exposure is uncertain. We investigated the association of stress resilience in adolescence with subsequent stroke risk.Methods Register-based cohort study. Some 237 879 males born between 1952 and 1956 were followed from 1987 to 2010 using information from Swedish registers. Cox regression estimated the association of stress resilience with stroke, after adjustment for established stroke risk factors.Results Some 3411 diagnoses of first stroke were identified. Lowest stress resilience (21.8%) compared with the highest (23.7%) was associated with increased stroke risk, producing unadjusted HR (with 95% CIs) of 1.54 (1.40 to 1.70). The association attenuated slightly to 1.48 (1.34 to 1.63) after adjustment for markers of socioeconomic circumstances in childhood; and after further adjustment for markers of development and disease in adolescence (blood pressure, cognitive function and pre-existing cardiovascular disease) to 1.30 (1.18 to 1.45). The greatest reduction followed further adjustment for markers of physical fitness (BMI and physical working capacity) in adolescence to 1.16 (1.04 to 1.29). The results were consistent when stroke was subdivided into fatal, ischaemic and haemorrhagic, with higher magnitude associations for fatal rather than non-fatal, and for haemorrhagic rather than ischaemic stroke.Conclusions Stress susceptibility and, therefore, psychosocial stress may be implicated in the aetiology of stroke. This association may be explained, in part, by poorer physical fitness. Effective prevention might focus on behaviour/lifestyle and psychosocial stress.

- Background: Influenza may precipitate cardiovascular disease but influenza typically peaks in winter coinciding with other triggers of myocardial infarction (MI) such as low air temperature, high wind velocity, low air pressure and short sunshine duration. We aimed to study week-to-week variation in influenza cases and acute MI after meteorological confounder adjustment in a nationwide setting.Methods: Weekly laboratory-confirmed influenza case reports were obtained from the Public Health Agency of Sweden from 2009 to 2016 and merged with the nationwide SWEDEHEART MI registry. Weekly counts of MI were studied with regard to influenza cases stratified into tertiles, 0–16, 17–164 and>164 influenza cases/week. Incidence rate ratios were calculated for each category and compared to a reference period of the year with no influenza. A negative binomial regression model was applied to adjust for weather parameters.Results: A total of 133 562 MIs were reported to the registry during the study period of which 44 055 were ST-elevation MIs. Weeks with influenza cases were associated with higher risk of MI. For 0–16 influenza cases/week the unadjusted incidence rate ratio (IRR) for MI was 1.04 (95% confidence interval [CI] 1.01–1.07, p=0.007); for 17–163 cases/week the IRR=1.07 (95% CI 1.04–1.10, p≤0.001) and for≥164 cases/week the IRR=1.08 (95% CI 1.05–1.11, p≤0.001). Results were consistent across a large range of subgroups and after adjusting for confounders. In addition, all-cause mortality was higher in weeks with highest reported rates of influenza cases.Conclusion: In this nationwide observational study, we found an association between occurrence of MI and number of influenza cases beyond what could be explained by meteorological factors.

- Scope: Diet rich in bilberries is considered cardioprotective, but the mechanisms of action are poorly understood. Cardiovascular disease is characterized by increased proatherogenic status and high levels of circulating microvesicles (MVs). In an open-label study patients with myocardial infarction receive an 8 week dietary supplementation with bilberry extract (BE). The effect of BE on patient MV levels and its influence on endothelial vesiculation in vitro is investigated.Methods and results: MVs are captured with acoustic trapping and platelet-derived MVs (PMVs), as well as endothelial-derived MVs (EMVs) are quantified with flow cytometry. The in vitro effect of BE on endothelial extracellular vesicle (EV) release is examined using endothelial cells and calcein staining. The mechanisms of BE influence on vesiculation pathways are studied by Western blot and qRT-PCR. Supplementation with BE decreased both PMVs and EMVs. Furthermore, BE reduced endothelial EV release, Akt phosphorylation, and vesiculation-related gene transcription. It also protects the cells from P2X(7)-induced EV release and increase in vesiculation-related gene expression.Conclusion: BE supplementation improves the MV profile in patient blood and reduces endothelial vesiculation through several molecular mechanisms related to the P2X(7)receptor. The findings provide new insight into the cardioprotective effects of bilberries.

- Objectives. The aim of the study was to assess long-term state and trait anxiety in cardiac surgical risk patients. Design. Thirty two patients with serum S100B > 0.3 µg/l 48 hours after cardiac surgery with cardiopulmonary bypass were matched according to age, gender, type, date and length of surgery with 35 operated patients without elevated S100B. They completed Spielberger's Anxiety Inventory (STAI). Results. Patients with elevated S100B reported more state anxiety and trait anxiety. S100B was an independent predictor of both state and trait anxiety when controlling for perioperative variables. Conclusions. Patients with elevated S100B reported more anxiety 3–6 years after cardiac surgery. A postoperative blood sample can identify risk patients and facilitate appropriate follow-up.

- Influenza vaccines are designed to mimic natural influenza virus exposure and stimulate a long-lasting immune response to future infections. The evolving nature of the influenza virus makes vaccination an important and efficacious strategy to reduce healthcare-related complications of influenza. Several lines of evidence indicate that influenza vaccination may induce nonspecific effects, also referred to as heterologous or pleiotropic effects, that go beyond protection against infection. Different explanations are proposed, including the upregulation and downregulation of cytokines and epigenetic reprogramming in monocytes and natural killer cells, imprinting an immunological memory in the innate immune system, a phenomenon termed "trained immunity". Also, cross-reactivity between related stimuli and bystander activation, which entails activation of B and T lymphocytes without specific recognition of antigens, may play a role. In this review, we will discuss the possible nonspecific effects of influenza vaccination in cardiovascular disease, type 1 diabetes, cancer, and Alzheimer's disease, future research questions, and potential implications. A discussion of the potential effects on infections by other pathogens is beyond the scope of this review.

- Increasing evidence suggests that probiotic supplementation may be efficacious in counteracting age-related shifts in gut microbiota composition and diversity, thereby impacting health outcomes and promoting healthy aging. However, randomized controlled trials (RCTs) with probiotics in healthy older adults have utilized a wide variety of strains and focused on several different outcomes with conflicting results. Therefore, a systematic review was conducted to determine which outcomes have been investigated in randomized controlled trials with probiotic supplementation in healthy older adults and what has been the effect of these interventions. For inclusion, studies reporting on randomized controlled trials with probiotic and synbiotic supplements in healthy older adults (defined as minimum age of 60 years) were considered. Studies reporting clinical trials in specific patient groups or unhealthy participants were excluded. In addition to assessment of eligibility and data extraction, each study was examined for risk of bias and quality assessment was performed by two independent reviewers. Due to the heterogeneity of outcomes, strains, study design, duration, and methodology, we did not perform any meta-analyses and instead provided a narrative overview of the outcomes examined. Of 1997 potentially eligible publications, 17 studies were included in this review. The risk of bias was low, although several studies failed to adequately describe random sequence generation, allocation concealment, and blinding. The overall study quality was high; however, many studies did not include sample calculations, and the majority of studies had a small sample size. The main outcomes examined in the trials included microbiota composition, immune-related measurements, digestive health, general well-being, cognitive function, and lipid and other biomarkers. The most commonly assessed outcome with the most consistent effect was microbiota composition; all but one study with this outcome showed significant effects on gut microbiota composition in healthy older adults. Overall, probiotic supplementation had modest effects on markers of humoral immunity, immune cell population levels and activity, as well as the incidence and duration of the common cold and other infections with some conflicting results. Digestive health, general-well-being, cognitive function, and lipid and other biomarkers were investigated in a very small number of studies; therefore, the impact on these outcomes remains inconclusive. Probiotics appear to be efficacious in modifying gut microbiota composition in healthy older adults and have moderate effects on immune function. However, the effect of probiotic supplementation on other health outcomes remains inconclusive, highlighting the need for more well-designed, sufficiently-powered studies to investigate if and the mechanisms by which probiotics impact healthy aging.

- BackgroundLong-term outcome in patients who suffered stroke after undergoing a cardiac operation has been investigated sparingly, but increased long-term mortality has been reported. S100B is a biochemical marker of brain cell ischemia and blood–brain barrier dysfunction. The aim of this investigation was to record the long-term mortality in consecutive patients undergoing cardiac operations and to explore whether increased concentrations of S100B in blood had a predictive value for mortality.MethodsProspectively collected clinical variables, including S100B, in 767 patients who survived more than 30 days after a cardiac operation, were analyzed with actuarial survival analysis and 678 patients were analyzed with Cox multiple regression analysis.ResultsForty-nine patients (6.4%) were dead at follow-up (range, 18 to 42 months); 11.5% (88 of 767 patients) had elevated S100B 2 days after operation (range, 38 to 42 hours). The probability for death at follow-up was 0.239 if the S100B level was more than 0.3 μg/L, and 0.041 if it was less than 0.3 μg/L. The clinical variables independently associated with mortality were preoperative renal failure, preoperative low left ventricular ejection fraction, emergency operation, severe postoperative central nervous system complication, and elevated S100B values, which turned out to be the most powerful predictor.ConclusionsEven slightly elevated S100B values in blood 2 days after cardiac operation imply a bad prognosis for outcome, and especially so in combination with any central nervous system complication.

- BackgroundThe brain-derived protein S100B has been shown to be a useful marker of brain injury of different etiologies. Cognitive dysfunction after cardiac surgery using cardiopulmonary bypass has been reported to occur in up to 70% of patients. In this study we tried to evaluate S100B as a marker for cognitive dysfunction after coronary bypass surgery with cardiopulmonary bypass in a model where the inflow of S100B from shed mediastinal blood was corrected for.Methods56 patients scheduled for coronary artery bypass grafting underwent prospective neuropsychological testing. The test scores were standardized and an impairment index was constructed. S100B was sampled at the end of surgery, hourly for the first 6 hours, and then 8, 10, 15, 24 and 48 hours after surgery. None of the patients received autotransfusion.ResultsIn simple linear analysis, no significant relation was found between S100B levels and neuropsychological outcome. In a backwards stepwise regression analysis the three variables, S100B levels at the end of cardiopulmonary bypass, S100B levels 1 hour later and the age of the patients were found to explain part of the neuropsychological deterioration (r = 0.49, p < 0.005).ConclusionsIn this study we found that S100B levels 1 hour after surgery seem to be the most informative. Our attempt to control the increased levels of S100B caused by contamination from the surgical field did not yield different results. We conclude that the clinical value of S100B as a predictive measurement of postoperative cognitive dysfunction after cardiac surgery is limited.
