#1
Petr Stastny, Michal Lehnert, James J Tufano
Many hamstring injuries that occur during physical activity occur while the muscles are lengthening, during eccentric hamstring muscle actions. Opposite of these eccentric hamstring actions are concentric quadriceps actions, where the larger and likely stronger quadriceps straighten the knee. Therefore, to stabilize the lower limbs during movement, the hamstrings must eccentrically combat against the strong knee-straightening torque of the quadriceps. As such, eccentric hamstring strength expressed relative to concentric quadricep strength is commonly referred to as the "functional ratio" as most movements in sports require simultaneous concentric knee extension and eccentric knee flexion...

There is a need for a method of real-time assessment of brain metabolism during neonatal hypoxic-ischaemic encephalopathy (HIE). We have used broadband near-infrared spectroscopy (NIRS) to monitor cerebral oxygenation and metabolic changes in 50 neonates with HIE undergoing therapeutic hypothermia treatment. In 24 neonates, 54 episodes of spontaneous decreases in peripheral oxygen saturation (desaturations) were recorded between 6 and 81 h after birth. We observed differences in the cerebral metabolic responses to these episodes that were related to the predicted outcome of the injury, as determined by subsequent magnetic resonance spectroscopy derived lactate/N-acetyl-aspartate...

This study aimed to reveal how metalworkers experience prolonged incapacity for work due to repetitive strain injury/work-related musculoskeletal disorder (RSI/WRMD) and the impact of chronic illness on the construction/deconstruction of masculinity. A qualitative study was performed, based on narrative interviews with male metalworkers in an automotive factory in the State of Bahia, Brazil. The results showed how the conflict in the experience of illness, the maintenance of male identity, and expectations of meeting the rules dictated by hegemonic masculinity are experienced and signified in daily life...

Latino day laborers are a socially and economically marginalized immigrant population with a high risk of occupational injury. These workers confront multiple social, psychological, and environmental hardships that increase their risk for adverse health outcomes. How these stressors interact and influence work-related injuries in this population remains unclear. We conducted an exploratory study with 327 Latino day laborers who completed a community survey. We developed a structural equation model, using cross-sectional data to explore the relationships among socioeconomic status, situational and immigration stress, depression, work risk exposure, and occupational injury...

Mammalian STE20-like kinase-1 (Mst1) is a generally expressed apoptosis-promoting kinase and a key bridgebuilder of apoptotic signaling in the etiology of tissue injury. Despite the fact that the biological function of Mst1 and its role in the cell's signalling network have yet to be determined, however, there is a lot of evidence that Mst1 plays an important role in cell death which result from tissue injury. Previous studies have shown that Mst1 is not only a target for some apoptosis-related molecules such as caspase 3 and P53,but aslo act as an activator of these proteinases to magnify apoptosis signal pathways...

A growing body of research points to the salience of the Internet and mobile material among individuals who self-injure. However, to date, no research has investigated the mobile apps related to nonsuicidal self-injury (NSSI). Such information would clarify which apps may be useful for those who self-injure while highlighting whether app-related content warrants improvement. The current study examined the content and usability of NSSI apps available on the two largest app-related platforms (Google Play and iTunes)...

BACKGROUND: Skin grafts following deep burns are needed to ensure healing. Grafts that fail and require re-grafting cause significant distress to patients and additional costs for the NHS. Shearing, which leads to graft loss, may be reduced through the use of low-friction bedding. A feasibility study was conducted to assess proof of concept for the use of low-friction bedding for patients with burns. Patient, parent and staff views on the acceptability of this material were explored through semi-structured interviews...

The peripheral immune system plays a critical role in aging and in the response to brain injury. Emerging data suggest inflammatory responses are exacerbated in older animals following ischemic stroke; however, our understanding of these age-related changes is poor. In this work, we demonstrate marked differences in the composition of circulating and infiltrating leukocytes recruited to the ischemic brain of old male mice after stroke compared to young male mice. Blood neutrophilia and neutrophil invasion into the brain were increased in aged animals...

Platelet concentrate (PC) transfusions are a lifesaving adjunct to control and prevent bleeding in cancer, hematologic, surgical, and trauma patients. Platelet concentrate availability and safety are limited by the development of platelet storage lesions (PSLs) and risk of bacterial contamination. Platelet storage lesions are a series of biochemical, structural, and functional changes that occur from blood collection to transfusion. Understanding of PSLs is key for devising interventions that prolong PC shelf life to improve PC access and wastage...

BACKGROUND: Ischemic stroke causes a multitude of brain damage. Neurovascular injury and myelin sheath degradation are two manifestations of ischemic brain damage. Therapeutic strategies aiming only at repairing the neural components or the vessels cannot efficiently restore neurological function. Endothelial progenitor cells (EPCs) have the advantages of both promoting angiogenesis and secreting trophic factors that would promote neurogenesis. Chemokine cxcl12 gene therapy has also been shown to promote angiogenesis, neurogenesis, and remyelination, attracting EPCs, neural progenitor cells, and oligodendrocyte progenitor cells (OPCs) to the injured sites of the brain...

OBJECTIVE: Despite viral suppression, HIV-associated cognitive impairment persists and may be partially due to persistent immune signaling by cells of the myeloid-lineage. Here we aimed to understand the contribution of activated microglia located in vulnerable brain regions (e.g., frontal, subcortical) of HIV-infected, virally suppressed (HIV+VS) individuals in relation to cognitive and motor function. DESIGN: 21 HIV+VS individuals underwent positron emission tomography (PET) with [C]DPA-713 to image the translocator protein 18 KDa (TSPO), a marker of microglial activation, and completed a comprehensive neuropsychological test battery...

BACKGROUND: Human trafficking in the fishing industry or "sea slavery" in the Greater Mekong Subregion is reported to involve some of the most extreme forms of exploitation and abuse. A largely unregulated sector, commercial fishing boats operate in international waters far from shore and outside of national jurisdiction, where workers are commonly subjected to life-threatening risks. Yet, research on the health needs of trafficked fishermen is sparse. This paper describes abuses, occupational hazards, physical and mental health and post-trafficking well-being among a systematic consecutive sample of 275 trafficked fishermen using post-trafficking services in Thailand and Cambodia...

PURPOSE: Primary revision amputation is the most common treatment method for traumatic digit amputations in the United States. Few studies have reported secondary revision rates after primary revision amputation. The primary aim of our study was to identify risk factors for secondary revision within 1 year of the index procedure. Secondarily, we describe the incidence and timing of complications requiring secondary revision. METHODS: Our institution's emergency department (ED) database was reviewed for traumatic digit amputations over a 6-year period...
