The effect of an oral sodium phosphate load on parathyroid hormone and fibroblast growth factor 23 secretion in normo- and hypercalciuric stone-forming patients.

BACKGROUND & AIMS: Abnormalities of parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23) secretion may cause calcium-phosphate (Ca-P) metabolism disorders in nephrolithiasis. Post-phosphate-load alterations in serum Ca, P and PTH, phosphaturia and calciuria enable monitoring hormonal regulation of Ca-P homeostasis. Our study aimed to determine differences in: 1.selected Ca-P metabolism parameters between healthy and kidney-stone-forming individuals, 2.PTH and FGF23 secretion induced by sodium-phosphate-load(NaP-load) in patients with/without hypercalciuria, 3.secretion of Ca-P related hormones in patients with low and normal/high serum concentrations of 25-hydroxyvitamin D3 (25OHD3). METHODS: Sodium phosphates NaH2PO4/Na2HPO4-100mmol were administered orally for five days in 19 hypercalciuric [urinary Ca(U-Ca) 6.5 ± 1.7 mmol/d]-HSF, 35 normocalciuric (2.5±1 mmol/d)-NSF stone-forming patients and 19 controls (U-Ca 2.5 ± 1.4 mmol/d)-CG. On days 1 and 5 PTH-,FGF23-,Ca-,P were determined before and after NaP-load. The areas under PTH, FGF23 curves (AUC) were calculated. U-Ca, urinary phosphate (U-P) and sodium (U-Na) were also determined. RESULTS: Following NaP-load, patients and controls exhibited expected alterations in Ca-P homeostasis. Despite changes in phosphate and PTH, no differences in FGF23 concentrations were observed. Patients differed from controls in having higher AUCPTH, calciuria and natriuresis, taking longer for PTH and P to normalize and lack of correlation between AUCPTH and phosphaturia. Post-NaP-load hypocalciuric effect of PTH secretion in NSF was less pronounced than in CG. In the HSFs, the hypocalciuric effect was more pronounced than in NSFs, but insufficient to correct hypercalciuria. In all stone-formers with low 25OHD3 concentrations, the AUCFGF23 was significantly increased on first (1215 ± 605vs766 ± 315 p = 0.0457) and fifth days (1211 ± 641vs777 ± 299 p = 0.041) of NaP-load, compared to normal/high 25OHD3-patients. Hypercalciuric patients with low 25OHD3 concentrations had greater AUCPTH5 than those with normal/high 25OHD3 (1005 ± 401vs835 ± 220 p = 0.0341). CONCLUSIONS: Compared to controls, kidney-stone-forming patients exhibited enhanced PTH secretion after NaP-load. The HSFs showed a more pronounced hypocalciuric effect than NSFs, but insufficient to correct hypercalciuria. In hypercalciuric stone-formers with low 25OHD3, FGF23 engagement in hyperphosphatemia reduction increased.

An assessment of diabetes-dependent quality of life (ADDQoL) in women and men in Poland with type 1 and type 2 diabetes.

INTRODUCTION: Quality of Life (QoL) of Polish women and men with type 1 diabetes (T1DM) and type 2 diabetes (T2DM) was analyzed, taking into consideration acceptance of the illness, the occurrence of depression, complications of diabetes, concentration of glycated haemoglobin, and demographic factors. MATERIAL AND METHODS: The study was conducted among 115 patients with T1DM and 215 patients with T2DM aged 18-60. The patients were divided into women and men. The tool applied for studying QoL was the Polish language version of the Audit of diabetes-dependent QoL questionnaire(ADDQoL) comprising 2 questions related to the general QoL and 19 domains related to aspects of life. Each domain included 2 components: Impact and Importance, and their product determined the value of the weighted impact score. The Acceptance of Illness Scale, Beck Depression Inventory and studied demographic and clinical parameters were also applied. RESULTS: Patients with both types of diabetes demonstrated a negative influence of the disease in all domains of ADDQoL. Values of the average weighted impact of ADDQoL showed significant associations with diabetic complications in T1DM and gender and depressive symptoms in T2DM. Diabetes negatively affects the QoL of diabetic patients in Poland, especially regarding freedom to eat and to drink and sex life in both genders in T1DM, and freedom to eat and drink, and feelings about the future in both genders, and working life and sex life in T2DM men. CONCLUSIONS: Risk factors for worse QoL are: the occurrence of diabetes complications in T1DM patients and male gender and depression in T2DM patients.

Psychometric properties of the Audit of Diabetes-Dependent Quality of Life (ADDQoL) in a population-based sample of Polish adults with type 1 and 2 diabetes.

BACKGROUND: The aim of the present paper was the assessment of the psychometric properties of the Polish language version of the Audit of Diabetes-Dependent Quality of Life (ADDQoL) questionnaire applied in Poland among patients with type 1 (T1DM) or type 2 diabetes (T2DM). METHODS: The studies were carried out among 330 patients with diabetes including 115 with T1DM and 215 with T2DM. In all the patients the level of the quality of life was investigated using the Polish language version of the ADDQoL and the psychometric properties were determined taking into consideration internal consistency, the factor loading and intraclass correlations. RESULTS: It was demonstrated that the values of internal consistency determining the reliability of the Polish language version of the ADDQoL for the overall Cronbach's alfa coefficient were 0.92 in the studied patients with T1DM and 0.93 in the studied patients with T2DM and the values of the loading factor were respectively 0.39-0.79 and 0.35-0.81. In the study of the correlation between the components of the ADDQoL the correlation coefficients proved to be highly statistically significant: in patients with T1DM r = 0.46-0.74 and in patients with T2DM - r = 0.42-0.80. CONCLUSION: The Polish language version of the ADDQoL is a reliable tool useful for the assessment of the level of the quality of life of adult patients with T1DM or T2DM in Poland and is recommended to be used among Polish-speaking patients with diabetes.

[Breast cancer prophylaxis among nurses]. / Profilaktyka raka piersi wsród pielegniarek.

Breast cancer is one of the most frequent malignant diseases among women. Breast cancer detection at an early stage is possible thanks to the active attitude of women themselves. The breast self-examination is a cheap and easy method for early detection of breast tumors. At the same time it can protect women from the development and long-term complications of that disease. The aim of the study was to evaluate the nurses' knowledge of the breast cancer prophylaxis and a range of its use for themselves. The research was conducted among 193 nurses taking part in qualification courses with the use of a questionnaire consisting of 20 questions. The results showed that 63% of nurses knew almost everything about the early breast cancer detection. Almost 50% of nurses did self-control regularly but unfortunately, not all of them did it correctly. Only 38% of participants were examined in outpatient clinics. 33% had mammography and 41% breast's USG. The results of the study are not optimistic. Despite medical education, the nurses are not knowledgeable enough about prevention and breast cancer detection. It also appeared that the nurses do not use their practical knowledge.
