To determine whether long-term daily consumption of milk containing probiotic Lactobacillus rhamnosus GG (GG) decreases respiratory illness in children.
A randomized, double-blind, placebo-controlled ...trial was conducted with 523 children aged 2-6 years attending day care centers in Finland. Subjects received either normal milk or the same milk with GG on three daily meals for 28 weeks. Daily recording of children' symptoms was done by parents. Primary outcome data from 501 subjects were available for analysis, and data from 128 subjects were analyzed as completed cases in terms of recovery of GG in fecal samples.
Number of days with at least one respiratory symptom in all subjects was 5.03/month (95% confidence interval (CI): 4.92-5.15) in the GG group and 5.17/month (95% CI: 5.05-5.29) in the placebo group incidence rate ratio (IRR) 0.97; 95% CI: 0.94-1.00; P=0.098). In the completed cases, the figures were 4.71 days/month (95% CI: 4.52-4.90) in the GG group and 5.67 days/month (95% CI: 5.40-5.94) in the placebo group (IRR 0.83; 95% CI: 0.78-0.88; P<0.001).
Consumption of GG reduced the occurrence of respiratory illness in children attending day care centers in the completed cases subgroup, but not in the total population. Thus, future clinical trials are warranted to clarify the association between fecal recovery of a probiotic and the symptom prevalence.
Summary
Background
Within a large prospective study, the Global Asthma and Allergy European Network (GA2LEN) has collected skin prick test (SPT) data throughout Europe to make recommendations for SPT ...in clinical settings.
Objective
To improve clinical interpretation of SPT results for inhalant allergens by providing quantitative decision points.
Methods
The GA2LEN SPT study with 3068 valid data sets was used to investigate the relationship between SPT results and patient‐reported clinical relevance for each of the 18 inhalant allergens as well as SPT wheal size and physician‐diagnosed allergy (rhinitis, asthma, atopic dermatitis, food allergy). The effects of age, gender, and geographical area on SPT results were assessed. For each allergen, the wheal size in mm with an 80% positive predictive value (PPV) for being clinically relevant was calculated.
Results
Depending on the allergen, from 40% (blatella) to 87–89% (grass, mites) of the positive SPT reactions (wheal size ≥ 3 mm) were associated with patient‐reported clinical symptoms when exposed to the respective allergen. The risk of allergic symptoms increased significantly with larger wheal sizes for 17 of the 18 allergens tested. Children with positive SPT reactions had a smaller risk of sensitizations being clinically relevant compared with adults. The 80% PPV varied from 3 to 10 mm depending on the allergen.
Conclusion
These ‘reading keys’ for 18 inhalant allergens can help interpret SPT results with respect to their clinical significance. A SPT form with the standard allergens including mm decision points for each allergen is offered for clinical use.
Background
The rehabilitation needs of patients with metastatic breast cancer (MBC) are poorly studied. The primary aim of the study was to evaluate the functional capacity of women with MBC and ...quality of life (QoL).
Methods
The present study is an open, non-randomized, prospective cross-sectional observation study. The functional capacity of 128 MBC patients with ongoing cancer treatments, were studied in Helsinki University Hospital (HUS): Peak expiratory flow (PEF), dynamic and static balance, 6 minute walking distance (6MWD), 10 meter walking, sit-to-stand test, repeated squat, grip strength, shoulder movement, pain, and QoL by Beck’s depression scale (BDI), health assessment questionnaire (HAQ), RAND SF-36 and EORTC QLQ-30 items.
Results
The walking capacity was compromised in half and the strength of the lower extremities in one-third of the patients. PEF was below the normal reference in 55 %, static balance in 62 % and dynamic balance in 73 % (≤60 year olds) and 81 % (≥61 year olds). The grip power was lowered in 44/30 % of the patients (right/left) and the shoulder movement was restricted in 30 %. Some disability in physical functioning experienced 55 % (HAQ) and 37 % felt depressive (BDI). The QoL (RAND SF-36) was poor especially in the field of physical, role and social functioning and bodily pain (<0.001). Pain, depression, and a poor 6MWD results independently determined the physical component of QoL (
p
< 0.001).
Conclusions
The functional capacity of patients with MBC was significantly lowered. This, in association with distressing symptoms like pain and depression causes a vicious circle further leading to functional disabilities and impaired QoL.
Summary
The ability of combined step aerobic- and circuit-training to prevent bone loss after breast cancer treatments was related to skeletal site and patients’ menopausal status. Among ...premenopausal breast cancer survivors, a 12-month exercise intervention completely prevented bone loss at the femoral neck, whereas no exercise effect was seen at lumbar spine or at neither site in postmenopausal women.
Introduction
The primary objective of this randomised clinical trial was to determine the preventive effect of supervised weight-bearing jumping exercises and circuit training on bone loss among breast cancer patients.
Methods
Of 573 breast cancer survivors aged 35–68 years randomly allocated into exercise or control group after adjuvant treatments, 498 (87%) were included in the final analysis. The 12-month exercise intervention comprised weekly supervised step aerobic- and circuit-exercises and similar home training. Bone mineral density (BMD) at lumbar spine and femoral neck were measured by dual-energy X-ray absorptiometry. Physical performance was assessed by 2-km walking and figure-8 running tests, and the amount of physical activity was estimated in metabolic equivalent-hours/week.
Results
In premenopausal women, bone loss at the femoral neck was prevented by exercise, the mean BMD changes being −0.2% among the trainees vs. −1.4% among the controls (
p
= 0.01). Lumbar bone loss could not be prevented (−1.9% vs. −2.2%). In postmenopausal women, no significant exercise-effect on BMD was found either at the lumbar spine (−1.6% vs. −2.1%) or femoral neck (−1.1% vs. −1.1%).
Conclusions
This 12-month aerobic jumping and circuit training intervention completely prevented femoral neck bone loss in premenopausal breast cancer patients, whereas no effect on BMD was seen in postmenopausal women.
Objectives: Self-rated health (SRH) is a well-known overall health status measure used in the general population but it is rarely examined in a clinical setting. We assessed SRH-related factors in ...clinic-based patients with rheumatoid arthritis (RA).
Method: The study included 123 consecutive outpatients treated in 1998-1999. Patient questionnaires, including a single SRH item, sociodemographics, the Health Assessment Questionnaire (HAQ) for functional ability, and the Nottingham Health Profile (NHP) for health-related quality of life (QoL), were collected at baseline. Comorbidities were measured by the Charlson Comorbidity Index (CCI) and data on the use of drugs and surgery for RA were verified from medical records and by querying patients. Factors associated with SRH were examined using regression models with the propensity score as the covariate. Mortality rates were collected up to 31 December 2014. Hazard ratios (HRs) were used to estimate SRH-associated mortality.
Results: In univariate analysis, poor SRH was associated with higher age and poorer patient-reported outcomes (PROs) but not with gender and clinical variables. After adjustment for the propensity score, the NHP dimensions for pain, energy, emotional reactions, and mobility remained significantly associated with SRH. The age- and sex-adjusted HR for death was 2.38 95% confidence interval (CI) 1.13-5.04, p = 0.034 for the patients with poor vs. good SRH. The propensity score-adjusted HR for death was 1.69 (95% CI 0.74-3.86, p = 0.21).
Conclusions In patients with RA, SRH was associated with health-related QoL dimensions, reflecting patients' well-being rather than clinical factors. During the 16 years of follow-up, SRH had no independent association with mortality.
Lactobacillus helveticus LBK-16H-fermented milk products containing tripeptides isoleucine-proline-proline and valine-proline-proline lower blood pressure in hypertensive subjects using office and ...home blood pressure registration. The present study was aimed to evaluate the effects of two doses of these lactotripeptides on 24-h ambulatory blood pressure and lipidomics profiles in mildly hypertensive subjects.
In a randomized, double-blind, placebo-controlled parallel group study, 89 mildly hypertensive subjects ingested, after a 1-month run-in period, a fermented milk drink with 5 mg per day of lactotripeptides during 3 months, and a milk drink with 50 mg per day of lactotripeptides for the following 3 months, or a placebo milk drink without lactotripeptides. Ambulatory blood pressure (24 h) was recorded at baseline and at the end of the intervention periods. Lipidomics profiles were characterized before and after the 6-month intervention.
After the second intervention period (50 mg per day of lactotripeptides), systolic and diastolic 24-h blood pressures decreased significantly in the peptide, but not in the placebo group. However, the treatment effects -2.6 mm Hg (95% confidence interval (CI): -5.7 to 0.4) in systolic and -1.3 mm Hg (95% CI: -3.4 to 0.8) in diastolic blood pressure did not reach statistic significance. Ingestion of 5 mg per day of lactotripeptides for 3 months did not lower blood pressure. The peptide group was dominated by decrease in multiple phospholipids (PL).
Ingestion of fermented milk with daily dose of 50 mg of lactotripeptides appears to lower elevated blood pressure slightly from the baseline, but not significantly compared with the placebo group and to induce significant decreases in multiple PL.
Objectives: To assess the impact of abdominal obesity (AO) on disease severity, cardiovascular risk factors, and patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA).
Method: ...Two hundred and thirty consecutive outpatients were cross-sectionally assessed. Waist circumference (WC) with a cut-off point of ≥ 102 cm in men and ≥ 88 cm in women indicated AO. Clinical assessment included joint counts, radiographs of small joints, and laboratory tests. Comorbidities and medication were verified from the patients' database. Patient questionnaires included sociodemographics, pain intensity, global disease activity, the Beck Depression Inventory (BDI), the Health Assessment Questionnaire (HAQ), physical activity level, and the 36-item Short Form Health Survey (SF-36). Metabolic syndrome (MetS) was defined according to the criteria of National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III). The association of AO with the 28-joint count Disease Activity Score (DAS28) and mental (MCS) and physical component scores (PCS) of the SF-36 and the HAQ was assessed by using regression models with the propensity score as a covariate.
Results: The AO prevalence was 52% in the 200 eligible patients. In a univariate analysis, AO was associated with cardiovascular risk factors, low HAQ score, physical inactivity, disease activity parameters, impaired MCS, higher pain, and increased use of biological drugs and antidepressants. In a multivariable model, only poorer DAS28 (p = 0.018) and poorer HAQ score (p = 0.004) remained significantly associated with AO.
Conclusions: AO is highly prevalent in patients with RA. In addition to cardiovascular risk factors, AO is associated with higher disease activity, higher disability, physical inactivity, more patients' perception of pain, and poorer mental health. Multifaceted promotion of lifestyle habits would be beneficial for improving AO-related health outcomes in patients with RA.
Objectives: Better treatment strategies and therapeutic options have changed the treatment of rheumatoid arthritis (RA) during the past decade. Our objective was to examine clinical and ...patient-reported outcomes in patients with RA treated in 1998-99 and 2011-12.
Method: The cross-sectional observational study included 303 consecutive outpatients (n = 103 in 1998-99 and n = 200 in 2011-12) from the same outpatient clinic. Patient questionnaires included patients' sociodemographics, the Health Assessment Questionnaire (HAQ) for functional ability, the Nottingham Health Profile (NHP) for health-related quality of life (HRQoL), self-reported general health (GH), and operations performed due to RA. A clinical examination was conducted for all patients. Comorbidities according to the Charlson Comorbidity Index (CCI), anti-rheumatic drugs and medications were recorded and the HAQ and NHP dimensions calculated. The results from these two patient cohorts were compared.
Results: The cohorts were comparable with regard to age, sex, and RA duration while the patients in the 2011-12 cohort were less often seropositive for rheumatoid factor (RF), had a better socioeconomic situation, better functional and working ability, and a decreased rate of RA surgery. The patients in 2011-12 had higher comorbidities and poorer GH while the HRQoL dimensions did not differ between the cohorts except for better mobility in 2011-12. Methotrexate (MTX) and combinations of conventional anti-rheumatic drugs were more frequently used in 2011-12. Biologicals were used only in 2011-12.
Conclusions: According to our results, more active anti-rheumatic therapy coincides with better RA-related outcomes. However, the result was the opposite with regard to overall health and comorbidities. Is this a new challenge in the treatment RA?
Background: A recent prospective study of children with asthma employing a within subject, over time analysis using dynamic logistic regression showed that severely negative life events significantly ...increased the risk of an acute exacerbation during the subsequent 6 week period. The timing of the maximum risk depended on the degree of chronic psychosocial stress also present. A hierarchical Cox regression analysis was undertaken to examine whether there were any immediate effects of negative life events in children without a background of high chronic stress. Methods: Sixty children with verified chronic asthma were followed prospectively for 18 months with continuous monitoring of asthma by daily symptom diaries and peak flow measurements, accompanied by repeated interview assessments of life events. The key outcome measures were asthma exacerbations and severely negative life events. Results: An immediate effect evident within the first 2 days following a severely negative life event increased the risk of a new asthma attack by a factor of 4.69 (p = 0.00). In the period 3–10 days after a severe event there was no increased risk of an asthma attack (p = 0.5). In addition to the immediate effect, an increased risk of 1.81 was found 5–7 weeks after a severe event (p = 0.002). This is consistent with earlier findings. There was a statistically significant variation due to unobserved factors in the incidence of asthma attacks between the children. Conclusion: The use of statistical methods capable of investigating short time lags showed that stressful life events significantly increase the risk of a new asthma attack immediately after the event; a more delayed increase in risk was also evident 5–7 weeks later.
