Influence of social competence of physicians on patient compliance with osteoporosis medications--a study on Polish postmenopausal women.

OBJECTIVE: The aim of the study was to examine the impact of social competence of physicians on the effectiveness of patient compliance and persistence with therapy. MATERIAL AND METHODS: The study included physicians and their patients, previously diagnosed with osteoporosis, and eligible to receive pharmacological treatment. The physicians were evaluated with the social competence questionnaire involving three dimensions: social exposure, intimacy and assertiveness, as well as in the combined scale. All patients in the study group were prescribed the same medication: alendronate once a week. Compliance and persistence of the patients were juxtaposed with social interaction skills of physicians during 7 scheduled appointments at 2-month intervals. RESULTS: Doctor's effectiveness in situations demanding close interpersonal contact was higher in the group with good compliance--group A (p < 0.001), as well as in the situations of social exposure, (p < 0.001). On the other hand, their assertiveness was higher in the group with poor compliance--group B (p < 0.001). Co-morbid conditions (group A: 76%, group B: 74%), as well as earlier fractures (40.43% vs. 36.78%) were comparable in both groups. Disease acceptance and suggested methods of treatment were more often accepted by patients from group A than group B (56% vs. 33%, respectively). CONCLUSIONS: (1) Disease acceptance is essential for effective treatment. (2) Social skills of physicians influence patient adherence to therapy recommendations. (3) Close interpersonal contact between physicians and their patients eliminates the feeling of fear and

[The role of anorexia nervosa in secondary osteoporosis development with the risk for low energy fractures]. / Rola jadlowstretu psychicznego w rozwoju wtórnej osteoporozy z uwzglednieniem ryzyka zlaman kosci.

Anorexia nervosa (AN) has in recent years become considerably more common. The disease primarily affects girls and young women, also boys and young men. AN is a risk factor for secondary osteoporosis. AN-related metabolic disturbances lead to diminished bone quality and increased risk of fractures. The consequences of low energy fractures are the main causes of death in women with AN. Hormonal disturbances (e.g. hypoestrogenism, increased levels of ghrelin and Y peptide, changes in leptin and endocannabinoid levels), as well as the mechanisms involved in bone resorption (RANK/RANKL/OPG system), are considered to be of great importance for anorectic bone quality. The risk for osteoporotic, non-vertebral fractures in AN patients is significantly higher than in healthy women. Improvement of bone mineral density is possible after substantial body mass increase. Weight loss, in conjunction with a well-balanced, controlled diet, is the key to correct peak bone mass levels, and diminishes the risk for osteoporosis with its consequence of low energy bone fractures.

Association between estrogen receptor alpha gene polymorphisms and bone mineral density in Polish female patients with Graves' disease.

Graves' (GD) hyperthyroidism leads to reduced bone mineral density (BMD) accompanied by accelerated bone turnover. Ample studies have identified association between estrogen receptor (ESR1) gene polymorphism and decreased BMD and osteoporosis. In contrast, number of publications that link ESR1, BMD and Graves' disease is limited. The purpose of this study was to identify the association between ESR1 polymorphisms and BMD in premenopausal women with GD and to determine whether ESR1 polymorphic variants can predispose to GD. The study included 75 women aged 23-46 years with GD and 163 healthy controls. BMD was measured at lumbar spine and femoral neck. We investigated two SNPs in the ESR1 gene and analyzed genetic variants in the form of haplotypes reconstructed by statistical method. Three out of four possible haplotypes of the PvuII and XbaI restriction fragment length polymorphisms were found in GD patients: px (55.3 %), PX (33.3 %) and Px (11.4 %). Women homozygous for xx of XbaI and for pp of PvuII had the lowest BMD at lumbar spine. Moreover, the px haplotype predisposed to reduced lumbar BMD. No associations were observed for femoral neck BMD. No statistically significant relationship were found between ESR1 polymorphisms or their haplotypes and GD. These results indicate that the PvuII and the XbaI polymorphisms of ESR1 gene are associated with bone mineral density in premenopausal women with GD and may help to estimate the risk of bone loss particularly at lumbar spine. However, none of the ESR1 gene alleles predict the risk of GD in Polish female patients.

A discussion of the intervention thresholds in osteoporosis treatment in Poland.

INTRODUCTION: Epidemiological prognoses regarding the global spread of post-menopausal osteoporosis can prove somewhat nebulous. But it is clear that low-energy fractures and their consequences will become an increasingly serious health problem. Therefore it is crucial to implement prognostic procedures which could more effectively predict the incidence of osteoporosis and its complications. MATERIAL AND METHODS: The study involved 378 female patients aged 40-86 years for whom clinical risk factors of osteoporotic fracture were analysed. Densitometry (DPX) was performed at femoral neck. The 10-year risk of fracture was assessed according to the British model of FRAX calculator. RESULTS: The study group was divided into two, depending on the history of low-energy fractures. Previous osteoporotic fractures were confirmed in 128 patients. In this group, the mean bone mineral density (BMD) values (0.717 g/cm(2)) were lower than in the group without fracture history (0.735 g/cm(2)). In 33.3% of patients aged 50-59 years and 17% of women aged 60-79 who required medical treatment for their clinical status (previous fracture), the FRAX value did not meet the criterion of pharmacotherapy administration. Considering BMD in the calculation of FRAX produced an even higher underestimation of the fracture risk. Of women aged 40-49, 25% were qualified for pharmacotherapy of osteoporosis. In that particular age category, BMD did not affect the FRAX value. BMD measurement had a higher discriminatory value among patients aged 50-79, increasing the number of patients requiring therapy by more than 50%. CONCLUSIONS: 1. The FRAX calculator does not always consider the history of low-energy fractures as a criterion sufficient for therapy implementation. 2. Designing a FRAX calculator specifically for the Polish population would be advisable.

The role of anorexia nervosa in secondary osteoporosis development with the risk for low energy fractures.

Anorexia nervosa (AN) has in recent years become considerably more common. The disease primarily affects girls and young women, and also boys and young men. AN is a risk factor for secondary osteoporosis. AN-related metabolic disturbances lead to diminished bone quality and increased risk of fractures. The consequences of low energy fractures are the main causes of death in women with AN. Hormonal disturbances (e.g. hypoestrogenism, increased levels of ghrelin and Y peptide, changes in leptin and endocannabinoid levels), as well as the mechanisms involved in bone resorption (RANK/RANKL/OPG), are considered to be of great importance for anorectic bone quality. The risk of osteoporotic, non-vertebral fractures in AN patients is significantly higher than in healthy women. An improvement of bone mineral density is possible after substantial body mass increase. Weight loss, in conjunction with a well-balanced, controlled diet, is the key to correct peak bone mass levels, and diminishes the risk of osteoporosis with its consequence of low energy bone fractures.

Influence of lean and fat mass on bone mineral density (BMD) in postmenopausal women with osteoporosis.

Despite known positive association between body mass and bone mineral density (BMD), relative contribution of fat and lean tissue to BMD remains under debate. We aimed at investigating the effect of selected anthropometric parameters, including fat content and lean body mass (LBM) on BMD in postmenopausal, osteoporotic women with body mass index (BMI) > 20 kg/m(2). The study involved 92 never-treated women (mean age 69.5 ± 7.3). L1-L4 and femoral neck (FN) BMD were measured by dual energy X-ray absorptiometry (DEXA). Absolute (kg) and relative (%) fat and LBM were assessed by means of electric bioimpedance method. We showed both FN and L1-L4 BMD were positively correlated with body mass, waist circumference (WC), hip circumference (HC) and LBM (kg). Fat content correlated with FN BMD (r = 0.36, p < 0.001). Regression analysis revealed the only predictor of L1-L4 BMD was LBM (R(2) = 0.18, p < 0.05), for FN--both LBM and fat (R(2) = 0.18, p < 0.05 and p < 0.001, respectively). Of the women, 44.5% were overweight, 18.4% obese. Obese women displayed the highest BMD. Both L1-L4 and FN BMD were higher in women with WC > 80 cm. In postmenopausal osteoporotic women with BMI > 20 kg/m(2) both fat and lean tissue might contribute to BMD. Positive association between body mass and BMD does not make obesity and osteoporosis mutually exclusive.

Vitamin D supplementation in adults - guidelines.

Vitamin D is necessary in maintaining appropriate calcium and phosphate homeostasis in the body (classical function) and ensuring appropriate functioning of many tissues, organs and cells, unrelated to mineral economy (non-classical function). Vitamin D deficiency in adults may cause osteomalacia, increase fracture risk in osteoporosis, induce cardiovascular diseases, diabetes type 1 and 2, multiple sclerosis, Lesniowski-Crohn disease, and cancer, including colon, breast, and prostate cancer. Possible causes of vitamin D deficiency in a healthy population include decreased cutaneous synthesis and an inadequate intake of vitamin D, both in food and in supplements. Vitamin D deficiency level (25(OH) D. 〈 20 ng/mL), is fairly widespread, being found in a substantial percentage of healthy subjects around the world, regardless of race, gender and age. Daily vitamin D dose, as determined by the Food and Nutrition Board in 1997, is now rather insufficient, the biggest problem being associated with maximal vitamin D levels (50 µg/day) in actually available food supplements. Nowadays, it is recommended that adults need a minimum of 800-1,000 U/day when their exposure to the sun is inadequate (in Poland from October to April). This dosage should be provided to all subjects who avoid sunlight, as well as to those aged over 65 because of their slower skin synthesis of vitamin D and for its proven anti-fracture and anti-fall effects.

Gender makes the difference: the influence of patients' gender on the delivery of preventive services in primary care in Poland.

OBJECTIVE: General practitioners' (GPs') time and resources for preventive services needs to be delivered equitably. We aimed to study the effect of patients' gender on the delivery of preventive procedures to adult patients aged 40 years and over. METHOD: An observational study was performed in primary care surgeries in Wielkopolska (Poland) as a part of the Improving Quality in Primary Care (PIUPOZ) programme carried out by Family Medicine Department of the University of Medical Sciences, Poznan. Trained observers directly observed GPs in their office, to register preventive procedures performed during the consultation and in the previous year (via the medical record) in patients aged 40 years and over. RESULTS: A total of 1073 preventive procedures were registered among 450 patients (267 women and 183 men) by 113 doctors in one year. The most common were serum glucose, blood pressure and total cholesterol measurements. Six procedures were offered to less than 10% of patients: dietary advice, tobacco use and alcohol screening, exercise counselling, body mass index (BMI) recording, and waist measurement. Men were more likely to receive tobacco use and alcohol screening and BMI measurement, while more women were offered a total cholesterol screen. CONCLUSIONS: The annual delivery rate of preventive procedures in patients aged 40 years and above is below the recommended level set by the Polish Ministry of Health. Procedures based on clinical examinations or laboratory tests were offered and performed more frequently than lifestyle advice. More men than women received preventive services for tobacco use or alcohol screening and BMI measurements. Patients' gender and physicians' engagement may influence GPs' preventive attitude and performance. These elements should be incorporated in the development of guidelines concerning prevention in primary care.

[Efficacy of densitometry and fracture risk assessment tool FRAX in making therapeutic decisions in osteoporosis--a study on female patients of university of medical sciences endocrinology outpatient clinic]. / Znaczenie densytometrii oraz zastosowania metody szacowania ryzyka zlamania osteoporotycznego za pomoca algorytmu FRAX dla podejmowania decyzji terapeutycznych w osteoporozie na przykladzie pacjentek Poradni Endokrynologicznej Uniwersytetu Medycznego w Poznaniu.

INTRODUCTION: Contemporary understanding of osteoporosis is based on the assessment of fracture risk. Evaluation of clinical risk factors of fracture with or without densitometry (DEXA) allows to identify patients requiring pharmacological treatment. AIM: The aim of the study was to estimate the usefulness of DEXA in assessment of fracture risk in women >50 years old. MATERIALS AND METHODS: In 296 previously untreated for osteoporosis women of Endocrinology Outpatient Clinic aged 50 to 85 years (mean 68.8+/-7.8) 10-year fracture risk using FRAX tool was computed from clinical risk factors alone (FRAX, FRAX hip) and after measurement of BMD (FRAX BMD). Then FRAX parameters were compared in 4 age categories. Fracture risk was confronted with therapeutic thresholds proposed in Poland. RESULTS: 10-year fracture risk by FRAX increased with age. The most frequent risk factors were: previous fracture and family history of fractures. FRAX and FRAX BMD were significantly different in the 50-59 year-olds and 60-69 year-olds. Statistically significant difference was found for FRAX hip and FRAX hip BMD in 50-59 year old women. FRAX and FRAXhip were better predictors of fractures than FRAX BMD in patients >80 years old. In 50-79 year old women qualification for treatment was more effective when risk was assessed according to FRAX BMD. DEXA performance did not change the number of women over 80 who were eligible for treatment according to FRAX. CONCLUSIONS: BMD is crucial for the 10-year risk assessment in 50-69 year-olds without previous fracture, as an increasing number of patients need therapy. In >80 year old women clinical risk factors alone are sufficient to make therapeutic decisions. DEXA in these women has no influence on the risk of future fractures, including hip fracture. In 60-69 women with previous fracture DEXA is a good predictor for future fractures but has no value as far as therapeutic decisions are concerned.

Reasons for visiting Polish primary care practices by patients aged 18-44 years: the largest emigrating age group.

Over 3% of the entire Polish population migrate for a job within the European Union, most are aged 18-44 years. The main destinations are Germany, the United Kingdom and Ireland. Immigration is connected with the use of many public services, including healthcare services. Assuming Polish immigrants require medical consultations in the countries they reside in, the authors have analysed the reasons for patients' visits to general practitioners (GPs) in Poland in order to predict possible reasons why Polish patients living abroad may make appointments with GPs in other countries. Data from 22,769 visits to GP practices between June 2005 and May 2006 by Polish patients aged 18-44 years were collected electronically. Age was categorised into three groups (18-24, 25-4 and 35-44 years) and the reason for the visit was categorised according to the ICD 10 coding system. Among the 12,535 patients registered with GPs, 73.1% of women and 68.6% of men required consultations during the year the study was conducted. The highest percentage of visits was recorded for women aged 35-44 years, while men of the same age were the least likely to visit a GP. The mean number of visits per patient ranged from 1.89 for men aged 25-34 years to 3.11 for women aged 35-44 years. The means were similar for 18- to 24-year-old men and women. Women aged 35-44 years had a higher mean number of visits compared with women aged 18-4 years, whereas the opposite was true for men. The analysis of reasons for visits within the age groups indicated that the percentage of appointments for respiratory problems and general and unspecified problems dropped by more than half from the 18-24-year-olds to the 35-44-years-olds, while visits for musculosceletal, cardiovascular, and mental and behavioural problems increased by a factor of four. The presented results intend to enable healthcare services meet Polish immigrants' healthcare needs.

Association analysis of vitamin D receptor gene polymorphisms with bone mineral density in young women with Graves' disease.

UNLABELLED: Graves' (GD) hyperthyroidism induces accelerated bone turnover that leads to decreased bone mineral density (BMD). The role of the VDR gene in predisposition to primary osteoporosis has been recognized. Recent studies show associations between the VDR gene polymorphisms and susceptibility to autoimmune diseases. Here we analyzed if VDR gene polymorphisms: BsmI, ApaI, TaqI, and FokI may predispose women with Graves' hyperthyroidism to BMD reduction or to disease development. The subjects were 75 premenopausal female Polish patients with GD and 163 healthy women. The genotyping was performed by the use of the restriction fragment length polymorphism analysis (RFLP). We studied the association of the VDR polymorphisms and their haplotypes with patients' BMD and also SNPs and haplotypes association with Graves' disease. We found a strong linkage disequilibrium for the BsmI, ApaI, and TaqI polymorphims that formed three most frequent haplotypes in Graves' women: baT (47.9%), BAt (34.9%), and bAT (16.4%). We did not show statistically significant association of analyzed VDR polymorphisms or haplotypes with decreased bone mineral density in Graves' patients. However, the presence of F allele had a weak tendency to be associated with Graves' disease (with OR=1.93; 95% CI: 0.97-3.84; p=0.058). IN CONCLUSION: VDR gene polymorphisms do not predict the risk of decreased BMD in Polish women with Graves'. It may be speculated that the F allele carriers of the VDR-FokI polymorphism are predisposed to Graves' disease development.

The TP53 codon 72 polymorphism and predisposition to adrenocortical cancer in Polish patients.

The TP53 polymorphism occurs at codon 72 of exon 4 with two alleles encoding either arginine or proline. The association between this common polymorphism and risk of different cancers has been extensive studied, however various reports are controversial. We have analyzed the 72Pro polymorphic variant in patients with adrenocortical tumors to evaluate whether 72G--> C substitution at codon 72 of TP53 gene may be associated with increased risk for malignancy in adrenal cortex in comparison to the control group. DNA extracted from peripheral leucocytes of 46 Polish patients with adrenocortical tumors (17 malignant and 29 benign) and 50 controls was examined by PCR-HD method followed by direct sequencing. TP53 polymorphism in codon 72 was found in 47% of ACC cases, in 28% of patients with adenomas and in 24% of controls. The genotype Arg/Arg, Arg/Pro and Pro/Pro distribution was respectively 53%/35%/12% for cancers, 72%/28%/0% for benign tumors and 76%/24%/0% for controls. High frequency of 72Pro allele in patients with carcinoma (29%) in comparison to the benign tumors (14%) and controls (12%) was statistically analyzed. We found that 72Pro variant of TP53 gene was associated with a significantly increased risk of ACC (OR = 3.05; 95% CI = 1.17-7.91, p=0.03). Our results suggest that the TP53 codon 72 polymorphism could be associated with susceptibility for adrenocortical cancer in the examined Polish patients.

The prognostic value of quality of life parameters in patients recovering from osteoporotic fractures of the proximal femur.

Background. Improving the quality of life is the aim of treatment in elderly patients with hip fracture. Different outcomes are often achieved using similar therapy methods. On the basis of own observations we tested the hypothesis that different parameters of quality of life (QOL) before hip fracture can be important prognostic factors. The aim of the study was to evaluate the association between selected QOL parameters and mortality after osteoporotic hip fracture at 2- and 12-month follow-up. Material and methods. We examined 55 patients ranging in age from 48 to 92 years (mean age 77 years) with hip fracture resulting from falls, who were treated in our surgery department. All patients answered a questionnaire constructed especially for this research. The patients were examined three times: first during hospitalization after surgery, the second time within 8 weeks, and the last time at follow-up one year after surgery. Results. 63% of those patients who died within 2 months lived alone, in comparison to 37% of patients living together with their families. 63% of the patients who needed continuous care died within the 8-week observation period. During this same time no patients who had been independent before hip fracture died. The one-year mortality rate among patients who did not leave their home before and after the fracture was 100%. A lack of social activity was associated with 82% mortality within 12 months. Conclusions. Quality of life parameters are important predictive factors for mortality in patients after hip fracture. High subjective quality of life assessment predicts better chances of recovery.
