Background: Conceptual models developed through qualitative research are based on the unique experiences of suffering and individuals' adoptions of each participant. A wide array of problems are faced by head-and-neck cancer (HNC) patients due to disease pathology and treatment modalities which are sufficient to influence the quality of life (QOL). Men possess greater self-acceptance and are better equipped with intrapersonal strength to cope with stress and adequacy compared to women...

OBJECTIVE: To investigate the effect of grip strength on bone mineral density (BMD) in postmenopausal women. Low BMD is related to risk of fracture and falling is the strongest factor for fragility fractures. Handgrip strength is a reliable indicator of muscle strength and muscle strength is associated with falling. METHODS: For the present study 120 women were divided into two groups: those ≤65 years and those >65 years. Serum 25 hydroxyvitamin D (25OHD), BMD, and handgrip strength were measured to observe the effect of age on 25OHD, grip strength, and BMD, as well as the effect of 25OHD on grip strength and BMD...

Most synaptic excitatory connections are made on dendritic spines. But how the voltage in spines is modulated by its geometry remains unclear. To investigate the electrical properties of spines, we combine voltage imaging data with electro-diffusion modeling. We first present a temporal deconvolution procedure for the genetically encoded voltage sensor expressed in hippocampal cultured neurons and then use electro-diffusion theory to compute the electric field and the current-voltage conversion. We extract a range for the neck resistances of 〈R〉=100±35MΩ...

PURPOSE: Malnutrition is a common complication in head, neck and lung cancer patients, particularly in cases of gastrointestinal system (GIS) cancer. Therefore, an assessment of malnutrition is crucial for early nutritional interventions. It was conducted as a cross-sectional study to evaluate nutritional status of adult cancer patients. METHODS: The nutritional status of 104 cancer patients (52 GIS and 52 non-GIS cancer cases) using a Patient-Generated Subjective Global Assessment (PG-SGA), handgrip strength, certain anthropometric measurements and food consumption in and outside of the hospital were assessed...

: Bone mineral density (BMD) measured by dual-energy x-ray absorptiometry (DXA) is used to assess bone health in HIV patients. DXA measures the amount of mineral, but not other key aspects of bone strength such as bone microarchitecture or bone quality. Trabecular Bone Score (TBS) and in vivo microindentation directly measure trabecular microarchitecture and bone tissue quality, respectively. The aim of this study is to measure bone strength properties using these techniques. RESULTS: Forty naïve HIV patients that were going to start antiretroviral (ART) a single pill treatment with Elvitegravir/cobicistat, Tenofovir (TDF), Emtricitavine (FTC) were included...

OBJECTIVE Spinal accessory nerve (SAN) injury results in a series of shoulder dysfunctions and continuous pain. However, current treatments are limited by the lack of donor nerves as well as by undesirable nerve regeneration. Here, the authors report a modified nerve transfer technique in which they employ a nerve fascicle from the posterior division (PD) of the ipsilateral C-7 nerve to repair SAN injury. The technique, first performed in cadavers, was then undertaken in 2 patients. METHODS Six fresh cadavers (12 sides of the SAN and ipsilateral C-7) were studied to observe the anatomical relationship between the SAN and C-7 nerve...

BACKGROUND: The majority of studies examining the role of cervical muscles on head-neck kinematics focused on musculoskeletal attributes (e.g. strength). Cervical neuromuscular response to perturbation may represent a divergent construct that has not been examined under various perturbation conditions. This study examined the association between cervical musculoskeletal attributes and cervical neuromuscular response of the sternocleidomastoid (SCM) to perturbation. Furthermore, this study examined the effect of anticipation and preload on the SCM neuromuscular response...

BACKGROUND: Successful fracture fixation depends critically on the stability of the screw-bone interface. Maximum achievable screw torque reflects the competence of this interface, but it cannot be quantified prior to screw stripping. Typically, the surgeon relies on the patients' bone mineral density and radiographs, along with experience and tactile feedback to assess whether sufficient compression can be generated by the screw and bone. However, the local bone quality would also critically influence the strength of the bone-screw interface...

REVIEW
Helen Anwander, Martin Beck, Lorenz Büchler
Anatomy and biomechanics of the human hip joint are a consequence of the evolution of permanent bipedal gait. Habitat and behaviour have an impact on hip morphology and significant differences are present even within the same biological family. The forces acting upon the hip joint are mainly a function of gravitation and strength of the muscles. Acetabular and femoral anatomy ensure an inherently stable hip with a wide range of motion. The femoral head in first human ancestors with upright gait was spherical (coxa rotunda)...

This study revealed that a quick and simple estimation of protein intake was related to measures of bone density and area in 70-year-old individuals. Furthermore, these associations were mediated by muscle mass when investigating peripheral measurement sites such as arms and legs. PURPOSE: Recent evidence suggests that dietary protein is beneficial for bone health in older individuals, but less is known about the influence of muscle mass on this relationship. This cross-sectional study aimed to investigate associations among protein intake, bone health, and muscle mass in 2332 men and women aged 70 years...

Hip fractures are associated with significant morbidity and mortality and a major health problem in the United States (). Eighty percent of hip fractures are experienced by 80-year-old women. Plain radiographs usually confirm the diagnosis, but if there is a high level of suspicion of an occult hip fracture, magnetic resonance imaging or bone scan is the next step to confirm the diagnosis. Areas of the hip bone have varied bone strength and blood supply, making the femoral neck one of the most vulnerable areas for fracture...

Aneurysm recurrence is the most critical concern following coil embolization of a cerebral aneurysm. Adequate packing density (PD) and coil uniformity are believed necessary to achieve sufficient flow stagnation, which decreases the risk of aneurysm recurrence. The effect of coil distribution on the extent of flow stagnation, however, especially in cases of dense packing (high PD), has received less attention. Thus, the cause of aneurysm recurrence despite dense packing is still an open question. The primary aim of this study is to evaluate the effect of local coil density on the extent of blood flow stagnation in densely coiled aneurysms...
