INTRODUCTION: Central venous cannulation may be difficult in morbidly obese patients. We present a case of successful right internal jugular vein catheterization under real-time ultrasound guidance in an obese patient in a forced semi-sitting position. CASE REPORT: A 43-year-old male patient with body mass of 182 kg (body mass index, 52.2 kg/m2 ) was admitted to the clinic 48 h after the trauma. The patient was in a forced semi-sitting position (37° head elevation)...

The purpose of this study was to identify physician actions that facilitate meaningful doctor-patient relationships, from the perspective of the medically underserved patient. Twenty-five patients were interviewed at the United Neighborhood Health Services Northeast Clinic in Nashville, Tennessee, which serves an underinsured patient population. Patients were asked to identify the qualities of engagement with their doctor that move beyond simple diagnosis and treatment. Interviews were audio-recorded, professionally transcribed, made anonymous, and analyzed by the grounded theory method of qualitative research...

BACKGROUND: Component alignment is an important consideration in total hip arthroplasty. The impact of changes in alignment on muscle forces and joint contact forces during dynamic tasks are not well understood, and have the potential to influence surgical decision making. The objectives of this study were to assess the impact of femoral head/stem and cup component placement on hip muscle and joint contact forces during tasks of daily living and to identify which alignment parameters have the greatest impact on joint loading...

Recent studies have demonstrated people's propensity to adopt others' visuospatial perspectives (VSPs) in a shared physical context. The present study investigated whether spontaneous VSP taking occurs in mental space where another person's perspective matters for mental activities rather than physical actions. Participants sat at a 90° angle to a confederate and performed a semantic categorization task on written words. From the participants' point of view, words were always displayed vertically, while for the confederate, these words appeared either the right way up or upside down, depending on the confederate's sitting position...

A near-infrared-light (NIR)- and UV-light-responsive polymer nanocomposite is synthesized by doping polymer-grafted gold nanorods into azobenzene liquid-crystalline dynamic networks (AuNR-ALCNs). The effects of the two different photoresponsive mechanisms, i.e., the photochemical reaction of azobenzene and the photothermal effect from the surface plasmon resonance of the AuNRs, are investigated by monitoring both the NIR- and UV-light-induced contraction forces of the oriented AuNR-ALCNs. By taking advantage of the material's easy processability, bilayer-structured actuators can be fabricated to display photocontrollable bending/unbending directions, as well as localized actuations through programmed alignment of azobenzene mesogens in selected regions...

BACKGROUND: Despite public health guidelines to limit sedentary behavior, many young children spend large amounts of time sedentary (eg, screen and sitting time) during waking hours. OBJECTIVE: The objective of this study was to test the feasibility and efficacy of a parent-focused, predominantly text message-delivered intervention to support parents to reduce the amount of time their children spend in sedentary behavior. METHODS: Mini Movers was a pilot randomized controlled trial delivered to parents of 2- to 4-year-old children in Melbourne, Australia...

There is evidence that patients with low back pain favor their trunk muscles when moving. However, it is unknown whether this maladaptive behavior is generalized across different functional tasks. This study analyzed the back muscle activity of patients with chronic low back pain compared to asymptomatic controls during five functional tasks. The secondary aim of this study was to test whether the electromyographic activity of patients' back muscles was correlated with either the TAMPA scale score or the Örebro Questionnaire...

Here we characterize persistent apogeotropic type of central positional nystagmus, and compare it with the apogeotropic nystagmus of benign paroxysmal positional vertigo involving the lateral canal. Nystagmus was recorded in 27 patients with apogeotropic type of central positional nystagmus (22 with unilateral and five with diffuse cerebellar lesions) and 20 patients with apogeotropic nystagmus of benign paroxysmal positional vertigo. They were tested while sitting, while supine with the head straight back, and in the right and left ear-down positions...

BACKGROUND: Total hip arthroplasty (THA) is in most cases improving patients´ life quality immediately after surgery. However, a closer look at these patients, especially with modern gait analysis methods, reveals also negative consequences due to the surgical approach related injury to the pelvic muscles. We hypothesized that this damage will have a negative impact on hip joint contact forces during activities of daily living (ADL). METHODS: 10 patients undergoing THA received an instrumented hip joint implant enabling real time in vivo measurements of hip joint loads using a direct lateral approach...

Although trunk muscles extend across multiple vertebral joints, recent motor control studies have shown that a top-down progression of trunk control in typical infants occurs incrementally, one segment at a time, until independent sitting. The current study merges this surprising developmental pattern with parent behavior by exploring the relationship between how parents hold their infant and the segmental level for which the infant exhibits postural control. We measured trunk control of 60 infants (1-8 months) via the segmental assessment of trunk control...

It is not as difficult to prevent and reduce violence as commonly assumed. The examination of peaceful societies and nonviolent social movements provides insight on how core values and norms like humility, respect for others, love and caring, forgiveness, and patience are fundamental in promoting peace. Additionally, nonviolent attitudes actualized through nonviolent models and non-punitive childrearing practices can help socialize children to become nonviolent adults. At the group level, the commitment to nonviolence by individuals using methods of sit-ins, boycotts, strikes, work slow-downs, civil disobedience, marches, and demonstrations in struggles against violence and oppression can bring about positive social change...

The obesity supine death syndrome refers to a catastrophic cascade of cardiorespiratory complications resulting from the supine positioning of a morbidly obese subject which can ultimately lead to death. It was first described in 1977 in two massively obese patients who were forced to lie down for medical procedures. But surprisingly, despite the current worldwide epidemic of obesity, very few cases have been reported yet. It can be assumed that the syndrome is poorly recognized in clinical practice and may participate in the high rate of unexplained death in morbidly obese patients...

This paper draws from Hägerstrand's space-time framework to generate new insights on the everyday mobilities of individuals with visual impairments in the San Francisco Bay Area. While existing research on visual impairment and mobility emphasizes individual physical limitations resulting from vision loss or inaccessible public spaces, this article highlights and bridges both the behavioral and social processes that influence individual mobility. A qualitative analysis of sit-down and mobile interview data reveals that the space-time constraints of people with visual impairments are closely linked to their access to transportation, assistive technologies, and mobile devices...

This study aimed to assess the factors associated with home meal preparation (HMP) and fast-food sources use (FFS) frequencies of low-income African-American adults and their healthy food beliefs and attitudes, food-related psychosocial factors, food acquisition patterns, food sources use, and BMI. We used cross-sectional data from 295 adults living in Baltimore, USA. HMP was inversely associated with FFS, which had lower odds of HMP ≥1 time/day and higher BMI scores. HMP was positively associated with positive beliefs and self-efficacy toward healthy foods, getting food from healthier food sources, and lower FFS...

Chronic pelvic pain (CPP) affects 24% of premenopausal women, accounts for 20%-30% of UK gynecology outpatient appointments, and has an annual pan-European economic cost of €3.8 billion. Despite extensive investigation, often including laparoscopy, up to 55% of women do not receive a diagnosis and endure persistent symptoms. In these patients, clinical management focuses on symptom control rather than treatment. It is possible that pelvic vein incompetence (PVI) is a cause of CPP, although the quality of studies investigating an association is generally low...
