Availability of psychological care in pediatric diabetes centers – a real need?
2023
Rolę multidyscyplinarnego zespołu diabetologicznego w leczeniu osoby z cukrzycą podkreślają zarówno polskie, jak i międzynarodowe zalecenia. Znaczenie dostępności opieki psychologicznej dla samopoczucia i zdrowia psychicznego osób z cukrzycą (i ich opiekunów), a także dla wyników leczenia cukrzycy jest przedmiotem licznych analiz. Pomimo rekomendacji i badań pokazujących korzyści z interwencji i wsparcia psychologicznego, brakuje danych na temat rzeczywistej dostępności takiej opieki zarówno w Polsce, jak i na świecie.
Progestogens and risk of breast cancer: a link between bone and breast?
2015
This article reviews the data supporting the role of receptor activator of the nuclear factor kappa (RANK) and its ligand, RANKL, in progestogen-induced breast cancer. Both experimental and clinical studies have been included. The expression of both RANK and RANKL has been described in epithelial cells of both mice and humans. Experiments of gain and loss of function in mice have shown that RANK/RANKL mediate alveologenesis during pregnancy or the estrous cycle. Moreover, the participation of the RANK/RANKL has been detected in models of breast carcinogenesis associated with progestogens-like medroxyprogesterone acetate. Recent clinical studies have found that the expression of RANK is asso…
Assessment of the tibia using ultrasonic guided waves in pubertal girls
2002
The purpose of this study was to compare low frequency ultrasonic guided wave measurements with established ultrasound and bone density measurements in terms of their ability to characterize the tibia in pubertal girls. Subjects were 12-14-year-old girls ( n=106) who were participating in a calcium and vitamin D intervention study. A prototype low frequency pulse transmission device consisting of a uniaxial scanning mechanism and low frequency transducers orientated perpendicularly to the limb was used to measure two ultrasound velocities in the tibia. The first velocity, V1, was that of the first arriving signal, similar to that measured by existing commercial tibial ultrasound devices. Th…
Case Report: Unmasking Hypercalcemia in Patients With Neuroendocrine Neoplasms. Experience From Six Italian Referral Centers
2021
BackgroundHypercalcemia is a common paraneoplastic syndrome which can occur in up to 10% of patients with advanced neoplasms. Paraneoplastic parathyroid hormone-related protein (PTHrP) represents the most frequent cause of this syndrome. In neuroendocrine neoplasms (NENs) paraneoplastic hypercalcemia is rare.Case SeriesThe present series includes all patients with NENs and paraneoplastic hypercalcemia from four Italian centres: (I) A 40-year-old man was hospitalized for repeated episodes of falls, hyposthenia and drowsiness. Severe hypercalcemia was found. Metastatic pancreatic G2 NEN and PTHrP-related hypercalcemia were diagnosed. The patient started therapy with somatostatin analogs (SSA)…
HLA Class II Differentiates Between Thyroid and Polyglandular Autoimmunity.
2015
The HLA class II genes are susceptibility genes for autoimmune endocrine diseases; however, scarce data are available pertaining to the determinants of genetic susceptibility to polyglandular autoimmunity (PGA). A total of 300 consecutive and unselected patients with either PGA or monoglandular autoimmune thyroid disease (AITD) and 100 healthy control subjects were genotyped for the HLA class II DRB1, -DQA1, and -DQB1 alleles. Compared to patients with AITD and controls, the HLA-DRB1*03 (pc =0.001), *04 (pc<0.001), -DQA1*03 (pc<0.001), and -DQB1*02 (pc =0.001) alleles were increased in patients with PGA. When dividing patients with Hashimoto's thyroiditis (HT) into those with PGA (PGA-HT) v…
Clinical performance of a highly portable, scanning calcaneal ultrasonometer.
2001
The aim of this study was to establish a normative database, assess precision, and evaluate the ability to identify women with low bone mass and to discriminate women with fracture from those without for a highly portable, scanning calcaneal ultrasonometer: the QUS-2. Fourteen hundred and one Caucasian women were recruited for the study. Among them were 794 healthy women 25–84 years of age evenly distributed per 10-year period to establish a normative database. Of these, 171 aged 25–34 years were defined as the young normal group for the purpose of T-score determination. Precision was assessed within 1 day (short-term) and over a 16-week period (long-term) in 79 women aged 25–84 years. Five…
Monitoring bone growth using quantitative ultrasound in comparison with DXA and pQCT.
2008
Quantitative ultrasound (QUS) is a safe, inexpensive, and nonradiation method for bone density assessment. QUS correlates with, and predicts fragility fractures comparable to, dual-energy X-ray absorptiometry (DXA)-derived bone mineral density (BMD) in postmenopausal women. However, its validity in monitoring bone growth in children is not well understood. Two hundred and fifty-eight 10-13 yr pubertal girls and 9 37-43 yr adults without diseases or history of medications known to affect bone metabolism were included in the 2-yr prospective study. Calcaneal broadband ultrasound attenuation (cBUA) was assessed using QUS-2 (Quidel, Santa Clara, CA), speed of sound of tibial shaft (tSOS) using …
Differences in estimates of change of bone accrual and body composition in children because of scan mode selection with the prodigy densitometer.
2004
Abstract Girls of age 10–13 yr with Tanner stage I–III maturation status ( n = 155) were measured using the Prodigy (GE Lunar) densitometer. Bone area (BA), bone mineral content (BMC), and bone mineral density (BMD) were assessed for the whole body, lumbar spine, and proximal femur using the Thin (T) and Standard (S) scan modes at years 1 and 3 of the study. The differences obtained between the T and S mode at year 1 were 1–2% for the lumbar spine and proximal femur and 5–11% for the whole body. For those girls whose default mode changed from T at year 1 to S mode at year 3, the estimated gain in BA, BMC, and BMD was 3.4%, 7.6%, and 3.1% respectively, lower than that obtained when scanning …
Estimation of structural and geometrical properties of cortical bone by computerized tomography in 78-year-old women
2009
The structural and geometrical properties of the tibia shaft were investigated at two sections by means of computerized tomography (CT) in 78-year-old women with high (n = 19) and low (n = 17) calcaneal bone mineral density (BMD, g/cm3) previously measured by 125I-photon absorption. The high BMD group had a 20-21% higher tibial BMD and 9-12% higher bone cross-sectional area than was observed in the low BMD group. The distribution of bone mass indicated that the low BMD group had lost bone mainly from the endosteal surface, especially in the anterior part of the tibia. However, both groups had a similar basic pattern of mass distribution at the measured sections. The high BMD group had highe…
Both Resistance and Agility Training Increase Cortical Bone Density in 75- to 85-Year-Old Women With Low Bone Mass
2004
A randomized, controlled, single-blinded 25-wk prospective study was conducted to compare the effects of group-based resistance and agility training on bone, as measured by both dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT), in older women with low bone mass. Ninety-eight community-dwelling women aged 75-85 yr were randomized to one of three experimental groups: resistance training (n = 32), agility training (n = 34), or stretching (sham exercise) (n = 32). Total hip, femoral neck, and trochanteric bone mineral density (BMD) were measured by DXA. Peripheral QCT measurements were performed at the tibia and radius. The pQCT outcome measures at t…
