Does Drinking Coffee and Tea Affect Bone Metabolism in Patients with Inflammatory Bowel Diseases?

Patients suffering from Crohn’s disease and ulcerative colitis are at higher risk of osteoporosis due to lower bone mineral density. Risk factors of osteoporosis are divided into unmodifiable, namely, age, gender, genetic factors, as well as modifiable, including diet, level of physical activity, and the use of stimulants. Coffee and tea contain numerous compounds affecting bone metabolism. Certain substances such as antioxidants may protect bones; other substances may increase bone resorption. Nevertheless, the influence of coffee and tea on the development and course of inflammatory bowel diseases is contradictory.     

A Vicious Cycle of Osteosarcopenia in Inflammatory Bowel Diseases—Aetiology,Clinical Implications and Therapeutic Perspectives

Sarcopenia is a disorder characterized by a loss of muscle mass which leads to the reduction of muscle strength and a decrease in the quality and quantity of muscle. It was previously thought that sarcopenia was specific to ageing. However, sarcopenia may affect patients suffering from chronic diseases throughout their entire lives. A decreased mass of muscle and bone is common among patients with inflammatory bowel disease (IBD). Since sarcopenia and osteoporosis are closely linked, they should be diagnosed as mutual consequences of IBD. Additionally, multidirectional treatment of sarcopenia and osteoporosis including nutrition, physical activity, and pharmacotherapy should include both disorders, referred to as osteosarcopenia.     

Analysis of Serum Fatty Acids Profile in Kidney Transplant Recipients

Patients with end-stage kidney disease, treated with renal transplantation, are at increased risk of cardio-vascular disease (CVD) and cardio-vascular mortality. They are also characterized by an atherogenic dyslipidemia. Alterations of the fatty acids (FA) profile contribute to increased cardio-vascular risk in the general population. In the current study we test the hypothesis that kidney transplantation is associated with ab-normalities in FA profile. FA profile was analysed by gas chromatography–mass spectrometry in 198 renal transplant recipients, and 48 control subjects. The most profound differences between renal transplant patients and controls were related to the content of branched chain FA, monounsaturated FA, and n-6 polyunsaturated FA, respectively. The FA profile significantly separated the patients from the controls in the principal component analysis (PCA). The abnormalities of FA profile showed a tendency for normalization in long-term kidney recipients, as compared to patients with recent transplants. The n-3 PUFA content demonstrated a strong inverse association with the presence of inflammation. Most profound alterations of the FA profile were observed in patients with impaired graft function (glomerular filtration rate < 45 mL/min). The study demonstrated significant disorders of the FA profile in kidney transplant recipients, that might contribute to cardio-vascular risk in this vulnerable patient population.     

Milk and Dairy Products: Good or Bad for Human Bone? Practical Dietary Recommendations for the Prevention and Management of Osteoporosis

Osteoporosis affects women twice as often as men. Additionally, it is estimated that 0.3 million and 1.7 million people have hip fractures in the USA and Europe, respectively. Having a proper peak bone mass and keeping it as long as possible is especially important for osteoporosis prevention. One of the most important calcium sources is milk and dairy products. Breast milk is the best infant food, but milk should not be avoided later in life to prevent losing bone mass. On the other hand, more and more people limit their milk consumption and consume other dairy or non-dairy products. For example, they are usually replaced with plant beverages, which should be consumed carefully in several age groups. Additionally, an important element of milk and dairy products, as well as plant beverages, are probiotics and prebiotics, which may modulate bone turnover. Dietary recommendations focused on milk, and dairy products are an important element for the prevention of osteoporosis.     

Associations of Lifestyle Factors with Osteopenia and Osteoporosis in Polish Patients with Inflammatory Bowel Disease

Reduced physical activity (PA), smoking, and coffee and alcohol drinking constitute risk factors of osteoporosis in patients with inflammatory bowel disease (IBD). The aim of the study was to measure the bone mineral density (BMD) and frequency of osteopenia and osteoporosis in patients with IBD and their correlation with PA, smoking, coffee, and alcohol. The study group consisted of 208 patients with IBD-103 with Crohn’s disease (CD), 105 suffering from ulcerative colitis (UC). Densitometric measurements were performed using the DXA. All patients completed a questionnaire concerning PA, smoking, and coffee and alcohol consumption. The prevalence of osteopenia and osteoporosis (L2–L4) in the IBD group was 48.1%; in the CD group, it amounted to 48.6%, and in the UC group, the prevalence was equal to 33.3%. Patients with CD who were diagnosed with osteopenia and osteoporosis demonstrated reduced PA compared to patients with a normal BMD who exercised regularly (p = 0.0335). A similar observation was made in the group of women with IBD. Women with a normal BMD exercised significantly more often than women suffering from osteopenia and osteoporosis (p = 0.0146). However, no differences in BMD were observed with regard to coffee use, alcohol consumption, or smoking. Thus, since the incidence of osteoporosis in IBD patients is high, it may be dependent on PA.     

Good practices in health promotion for older people – Significance for evidence in health policy

This article is devoted to convincing policy makers to use good practices in encouraging older people to pursue adequate and effective health policies. Long-term scientific research focused on the effects of health promotion programmes is rarely undertaken, although its scope is still expanding. At the same time, it is strongly desirable to form health policy based on scientific evidence. In this situation, an indication of good practices characterised by precisely defined features and their systematic evaluation could be an alternative to an insufficient number of empirical studies. The first step of the methodology was a literature review on health promotion for older people, aimed at defining good practices and criteria used for their selection. The authors searched the following databases: PubMED, Embase and Cochrane Library, as well as international databases dedicated to health promotion programmes for older people (e.g. Age-friendly World ( https://extranet.who.int/agefriendlyworld/age-friendly-practice-database-launched ); HealthProElderly ( www.healthproelderly.com/database/index.php?id=16 ); JA-CHRODIS ( www.chrodis.eu ); EuroHealthNet ( www.eurohealthnet.eu ) and ProFouND; ( www.profound.eu.com ). As relevant health policy information is usually available in national languages, the authors then approached national experts in 10 European countries, who filled in a dedicated survey on health promotion programmes for older people and indicated examples of good practices from their countries. Practical evidence, based on real implemented programmes, is valuable as inspiration for health promotion programmes, their planning and management. Selecting good practices from among implemented and evaluated actions makes it possible to establish their value. The significance of good practices in health promotion is to deliver real benefits and health effects for a target group, which, in the case of evident benefits, renders the practices credible and worthy of further dissemination. The EU already successfully shares good practices in migrant health and environmental protection. Creating databases on good practices helps policy makers promote the sustainability of already implemented activities and enhances their applicability by other organisations and in different settings.     

The effect of soy isoflavones on the development of intestinal neoplasia in Apc mouse

Data from epidemiological studies suggest that isoflavones in soy may have a protective effect on the development of colon cancer in humans. Therefore, we have investigated whether soy isoflavones will inhibit intestinal tumour development in Apc^Min mice. The mice were fed a Western-type high risk diet (high fat, low fibre and calcium) containing two different isolates of soy protein as a protein source. For the control and test groups this resulted in the administration of about 16 and 475 mg of total isoflavones per kg diet, respectively. As a positive control, a third group of mice was administered a low isoflavone diet supplemented with 300 ppm sulindac. No significant differences in the incidence, multiplicity, size and distribution of intestinal tumours were observed between Min mice fed low and high isoflavone-containing diets. However, a clear reduction in the number of small intestinal tumours was observed for the sulindac diet. Thus, in contrast to epidemiological studies, our results demonstrate that high amounts of soy isoflavones present in a Western-type high risk diet do not protect against intestinal tumour development in a relevant animal model such as the Min mice.     

A prospective study of dietary folate intake and risk of colorectal cancer: modification by caffeine intake and cigarette smoking.

Epidemiologic evidence indicates an inverse association of folate intake with risk of colorectal cancer, but whether this association is modified by intake of caffeine (in coffee and tea) or cigarette smoking--factors that possibly interfere with folate--has not been studied. Thus, we examined whether the association between dietary folate intake and incidence of colorectal cancer is modified by caffeine intake and smoking. Cox proportional hazards modeling was used to estimate rate ratios relating dietary folate intake to colorectal cancer incidence among 61,433 women ages 40 to 75 years at recruitment into the Swedish Mammography Cohort in 1987 to 1990. From March 1987 through June 2004, a total of 805 incident cases of colorectal cancer were diagnosed. After controlling for age and other potential confounders, we observed an inverse association between dietary folate intake and risk of colon cancer (rate ratio for the highest versus the lowest quintile, 0.61; 95% confidence interval, 0.41-0.91; P(trend) = 0.02), but not of rectal cancer (rate ratio, 0.93; 95% confidence interval, 0.55-1.56; P(trend) = 0.97). The inverse association between dietary folate intake and colon cancer risk was most pronounced among smokers (P(interaction) = 0.03). We found no apparent modification of risk by caffeine intake. Findings from this population-based cohort study support an inverse association between dietary folate intake and risk of colon cancer and suggest that smokers might benefit most from a high dietary folate intake.     

Anxiety and depression and their influence on the quality of life after total hip replacement: preliminary report

Objective. The study investigated health-related quality of life in relation to mental status (anxiety and depression) and demographic factors in patients before and after total hip replacement due to osteoarthrosis. Methods. The SF-36, HADS, socio-demographic data questionnaire was delivered to a group of 184 subjects (108 females, 76 males) at the mean age at the time of surgery of 59 years. Questionnaires were delivered to the subjects 2 weeks before the surgery and 6 months after the operation (by mail). Results. Patients after hip replacement showed significant improvement in health-related quality of life in most domains of SF-36 score and summary scale of PCS (Physical Component Summary Scale) and MCS (Mental Component Summary Scale). They also showed improvement in mental status. Elderly patients were more likely to show worse score in MCS and PCS before and after surgery. BMI (body mass index) was correlated only with preoperative PCS. Mental status was associated with postoperative PCS and MCS. Patients who were satisfied with the results of the surgery showed higher PCS and MCS score. Conclusion. Hip replacement surgery brings significant improvement to the quality of life. Age and mental status of those patients influence markedly their postoperative performance.
