FRI0299 Prevalence of Vertebral Fractures in Osteoporotic HIP Fractured Patients: The Focus Study
2015
Background Osteoporosis is a multifactorial systemic skeletal disease, characterized by low bone mass and microarchitectural modifications of bone tissue, with a consequent increase in fragility fractures [1]. Vertebral fractures are the most prevalent osteoporotic fractures and osteoporotic hip fractures are the most serious complication of osteoporosis resulting in increased mortality and high socio-economic cost [2,3]. The coexistence of these two pathological conditions in elderly patients has been previously described, leading to even worse functional outcomes than each one alone [4]. Objectives To determine the prevalence of vertebral fractures in osteoporotic hip fractured women and …
Dynamic in vitro dehydration patterns of unworn and worn silicone hydrogel contact lenses.
2008
Purpose: To evaluate the effect of wear on dynamic in vitro dehydration of silicone hydrogel (Si-Hi) contact lens (CL) using a previously described gravimetric procedure. Methods: Five different silicone hydrogel (Si-Hi) contact lenses (CL) were evaluated after being worn by patients under daily wear conditions for 15 days to 1 month. Lenses were conditioned and disinfected with a multipurpose solution after each day of wear. Lenses were left to dehydrate in an analytical balance under controlled conditions of temperature and relative humidity and the results compared with data from new lens samples of the same power and material. Several quantitative parameters were obtained and compared b…
Effects of calcium, dairy product, and vitamin D supplementation on bone mass accrual and body composition in 10-12-y-old girls: a 2-y randomized tri…
2005
Little is known about the relative effectiveness of calcium supplementation from food or pills with or without vitamin D supplementation for bone mass accrual during the rapid growth period.The purpose was to examine the effects of both food-based and pill supplements of calcium and vitamin D on bone mass and body composition in girls aged 10-12 y.This placebo-controlled intervention trial randomly assigned 195 healthy girls at Tanner stage I-II, aged 10-12 y, with dietary calcium intakes900 mg/d to 1 of 4 groups: calcium (1000 mg) + vitamin D3 (200 IU), calcium (1000 mg), cheese (1000 mg calcium), and placebo. Primary outcomes were bone indexes of the hip, spine, and whole body by dual-ene…
Changes in Motor, Cognitive, and Behavioral Symptoms in Parkinson's Disease and Mild Cognitive Impairment During the COVID-19 Lockdown
2020
Objective: The effects of the COVID-19 lockdown on subjects with prodromal phases of dementia are unknown. The aim of this study was to evaluate the motor, cognitive, and behavioral changes during the COVID-19 lockdown in Italy in patients with Parkinson's disease (PD) with and without mild cognitive impairment (PD-MCI and PD-NC) and in patients with MCI not associated with PD (MCInoPD).Methods: A total of 34 patients with PD-NC, 31 PD-MCI, and 31 MCInoPD and their caregivers were interviewed 10 weeks after the COVID-19 lockdown in Italy, and changes in cognitive, behavioral, and motor symptoms were examined. Modified standardized scales, including the Neuropsychiatric Inventory (NPI) and t…
Inhibitory effects of okadaic acid on rat uterine contractile responses to different spasmogens
1997
In the present study, we examined the effects of okadaic acid, a selective inhibitor of type I and 2A protein phosphatases, on the mechanical responses evoked by oxytocin, K + - and Na + -modified solutions and ouabain in estrogen-primed rat myometrium. Oxytocin elicited a rapid, phasic contraction followed by rhythmic oscillations. The phasic response was partially resistant to the absence of external Ca 2+ . Okadaic acid (1 μM) and the L-type calcium channel blocker nifedipine (1 μM) abolished the oscillatory component and reduced the initial, phasic response to about 80% of the control response. High K + (60 mM) solution, ouabain (1 mM), K + -free medium and low Na + (25 mM) solution ind…
Discrepancy between food offered and consumed during hospitalization in older adult patients
2020
AbstractMalnutrition is one of the most frequent geriatric syndromes and a key contributor to frailty. Ageing is commonly associated with modifications in eating habits with changes in appetite and food intake. Malnutrition is not only a sign of illness, but its presence increases morbidity, hospital stay, institutionalization, poor quality of life, in-hospital complications, expenses, and mortality. Hospitalized patients have increased calorie requirements to overcome the increased energy expenditure due to acute disease. We aimed to evaluate the actual consumption of the food offered to a sample of hospitalized older adults. Sixty hospitalized patients (women/men = 23/37) were recruited s…
Effect of oral magnesium supplementation on physical performance in healthy elderly women involved in a weekly exercise program: A randomized control…
2014
Background: Magnesium deficiency is associated with poor physical performance, but no trials are available on how magnesium supplementation affects elderly people’s physical performance. Objective: The aim of our study was to investigate whether 12 wk of oral magnesium supplementation can improve physical performance in healthy elderly women. Design: In a parallel-group, randomized controlled trial, 139 healthy women (mean 6 SD age: 71.5 6 5.2 y) attending a mild fitness program were randomly allocated to a treatment group (300 mg Mg/d; n = 62) or a control group (no placebo or intervention; n = 77) by using a computer-generated randomization sequence, and researchers were blinded to their …
Perioperative care of the elderly oncology patient: A report from the SIOG task force on the perioperative care of older patients with cancer
2012
Abstract The increasing number of older cancer patients seen in daily practice demands reflection on how to optimize their care during the perioperative period. Optimally tailored surgical management, at present the most successful cancer treatment, firmly rests on an accurate and careful anesthesiological management. The unique peculiarities of anesthesia in older cancer patients prompted the International Society of Geriatric Oncology (SIOG) to put together a panel of international experts with the aim of reviewing the literature and drafting a consensus document. This article summarizes their views.
Calcium Dependence of the Mechanical Response Evoked by Okadaic Acid in Smooth Muscle
1995
The effects of okadaic acid (OA), obtained from a culture of the marine dinoflagellate Prorocentrum Lima were studied on isolated strips of rat myometrium. The contractile response evoked by OA at 5, 10, and 20 μM in normal physiological solution was unaffected in the presence of tetrodotoxin (10 μM), indomethacin (3 μM), or a cocktail of antagonists which blocked muscarinic, adrenergic, histaminergic, serotonergic, and opioid receptors. Similarly, the response to OA was unaffected in the presence of nifedipine at a concentration (1 μM) which completely or highly blocked the response to KCl (60 mM), oxytocin (1 μM), or acetylcholine (100 μM). In a Ca 2+ -free 1 mM EGTA-containing solution, …
Pruritus precipitated by hydroxyethyl starch: a review.
2005
Summary Hydroxyethyl starch (HES) is widely used for fluid management in broad populations of patients, particularly in the surgery and intensive care settings. Pruritus, often manifested as pruritic crises, is increasingly being recognized as a common major adverse effect of HES administration. This iatrogenic form of pruritus is frequently severe and protracted with a serious negative impact on patient quality of life, including sleep disturbance, disruption of daily routine and mental distress. Such pruritus is generally refractory to available therapies and can persist for up to 12–24 months. All currently clinically available HES solutions entail the risk of pruritus, including those o…
