The unsolved case of “bone-impairing analgesics”. The endocrine effects of opioids on bone metabolism [PDF]

, 2015
The current literature describes the possible risks for bone fracture in chronic analgesics users. There are three main hypotheses that could explain the increased risk of fracture associated with central analgesics, such as opioids: 1) the increased ...

Seismic AVOA Inversion for Weak Anisotropy Parameters and Fracture Density in a Monoclinic Medium

Applied Sciences, 2020
In shale gas development, fracture density is an important lithologic parameter to properly characterize reservoir reconstruction, establish a fracturing scheme, and calculate porosity and permeability.

Diabetes, Bone Density, and Fractures [PDF]

Journal of Diabetes & Metabolism, 2012
All types of diabetes increase risk for osteoporosis and fracture due to multiple factors. Hyperglycemia itself may play a role, but frequent hypoglycemia, falls, hypogonadism, vitamin D deficiency, body mass index (BMI), and advanced complications may play an even larger role.

Muscle density is an independent risk factor of second hip fracture: a prospective cohort study

Journal of Cachexia, Sarcopenia and Muscle, 2022
Background Patients with a first hip fracture are at high risk of fracturing their other hip. Despite this, preventive therapy is often not given.

Study on Flow in Fractured Porous Media Using Pore-Fracture Network Modeling

Energies, 2017
Microscopic flow in fractured porous media is a typical problem for the exploitation of tight reservoirs. The rapid-flow in the fractured porous-media is of great significance to efficient and continuous oil/gas exploitation.

Selection of risk assessment methods for osteoporosis screening in postmenopausal women with low-energy fractures: A comparison of fracture risk assessment tool, digital X-ray radiogrammetry, and dual-energy X-ray absorptiometry

SAGE Open Medicine, 2022
Objectives: Fracture liaison services are designed to identify patients needing osteoporosis treatment after a fracture. Some fracture liaison service designs involve a prescreening step, for example, fracture risk assessment tool (FRAX ® ).

Decreased bone mass in adolescents with bone fragility fracture but not in young children: a case–control study

Frontiers in Endocrinology, 2023
BackgroundThe incidence of distal forearm fracture due to minimal/moderate trauma shows a bimodal distribution for age at event, with one peak occurring during early adolescence, in both boys and girls and the other one in postmenopausal females. The aim

Application of a multi-layer feedforward neural network to predict fracture density in shale oil, Junggar Basin, China

Frontiers in Earth Science, 2023
Fengcheng Formation in the Mabei Slope of Junggar Basin has low porosity and permeability. However, fractures are well developed, representing an effective storage space for shale oil.

Prevention of osteoporotic refractures in regional Australia [PDF]

, 2017
Objective: Clinical guidelines recommend that patients who sustain a minimal trauma fracture (MTF) should receive a bone mineral density (BMD) scan and bisphosphonate (or equivalent) therapy if diagnosed with osteoporosis.

Fracture energy of gels

, 2000
To clarify effects of crack speed and cross-link density on fracture energy of acrylamide gels, we evaluated the roughness of the fracture surface and measured the fracture energy taking into account the roughness.
