Avascular necrosis (AVN) of the capitate is a rare clinical entity for which a variety of treatment options have been described, ranging from immobilization to microvascular bone transfer. Outcomes following medial femoral condyle corticocancellous free flap reconstruction have not been reported for this specific pathology. We present the case of a 16-year-old girl with posttraumatic capitate AVN who was treated with curettage and medial femoral condyle corticocancellous vascularized bone grafting. At 18 months after surgery, the patient remains pain-free and had resumed all activities including lifeguarding by 6 months after surgery...

Golgi anti-apoptotic protein (GAAP), also known as transmembrane Bax inhibitor-1 motif-containing 4 (TMBIM4) or Lifeguard 4 (Lfg4), shares remarkable amino acid conservation with orthologues throughout eukaryotes, prokaryotes and some orthopoxviruses, suggesting a highly conserved function. GAAPs regulate Ca(2+) levels and fluxes from the Golgi and endoplasmic reticulum, confer resistance to a broad range of apoptotic stimuli, promote cell adhesion and migration via the activation of store-operated Ca(2+) entry, are essential for the viability of human cells, and affect orthopoxvirus virulence...

The aim of the present study was to use an enzyme-linked immunosorbent assay (ELISA) to determine the concentrations of Lifeguard (LFG) protein in the serum of 36 patients diagnosed with breast cancer and to compare these values with the concentrations of LFG protein in the serum of 7 healthy volunteers in order to detect a possible association between the expression of LFG in the serum and the degree of malignancy of the disease. Although there is no direct association between the LFG protein concentration in the serum and the degree of malignancy of breast cancer, a statistically significant distribution of the concentration in all investigated samples was observed...

Research on workplace injuries and exposures in ocean safety personnel remains limited. Despite increasing beach attendance and reliance on lifeguards for protection, the most common types of injuries, equipment resulting in injuries, and environmental exposures remains unknown. This study reviewed OSHA 300 logs summarizing workers' compensation claims from 2007-2012 to identify common body parts injured, action at time of injury, equipment causing injury, and environmental exposures. A secondary phase consisted of a cross-sectional anonymous survey to determine demographics, body part injured, equipment causing injury, sun and environmental exposures, action at time of injury, and proportion of injuries reported to the department...

PURPOSE: Drowning is a high-priority public health problem around the world. The European Resuscitation Council Guidelines for Resuscitation 2015 put special emphasis on special environments like open waters. Stopping the drowning process as soon as possible and starting an early cardiopulmonary resuscitation (CPR) improve survival. Inflatable rescue boats (IRBs) are used around the world in the water rescue of drowning victims. Our objective was to test the quality of CPR performed by surf-lifeguards while sailing on an IRB...

BACKGROUND: Drowning leading to out-of-hospital cardiac arrest (OHCA) and death is a major public health concern. Submersion with duration of less than 10min is associated with favorable neurological outcome and nearby bystanders play a considerable role in rescue and resuscitation. Drones can provide a visual overview of an accident scene, their potential as lifesaving tools in drowning has not been evaluated. AIM: The aim of this simulation study was to evaluate the efficiency of a drone for providing earlier location of a submerged possible drowning victim in comparison with standard procedure...

Lifeguard is an integral transmembrane protein that modulates FasL-mediated apoptosis by interfering with the activation of caspase 8. It is evolutionarily conserved, with homologues present in plants, nematodes, zebra fish, frog, chicken, mouse, monkey, and human. The Lifeguard homologue in Drosophila, CG3814, contains the Bax inhibitor-1 family motif of unknown function. Downregulation of Lifeguard disrupts cellular homeostasis and disease by sensitizing neurons to FasL-mediated apoptosis. We used bioinformatic analyses to identify CG3814, a putative homologue of Lifeguard, and knocked down CG3814/LFG expression under the control of the Dopa decarboxylase (Ddc-Gal4) transgene in Drosophila melanogaster neurons to investigate whether it possesses neuroprotective activity...

OBJECTIVE: Cardiopulmonary resuscitation (CPR) after a drowning episode is performed under fatigue conditions. However, the characterization of CPR in this context is still unknown. Our purpose was to investigate the effect of a 100-m simulated in-water rescue on CPR and physiological parameters in trained certified lifeguards. METHODS: Thirty trained certified lifeguards (age 24.6 ± 3.8 yrs; height 178.2 ± 7.4 cm and weight 76.9 ± 10.6 kg) completed two protocols using an adult manikin: (i) 4-min CPR after 4-min baseline conditions (CPR), and (ii) 4-min CPR after a 100-m simulated in-water rescue in the sea (CPR Rescue), both with a compression-ventilation ratio of 30:2...

To prevent drowning incidents in French public swimming pools (PSP), bathing must be constantly supervised by qualified lifeguards. However, fatal drownings regularly occurs in supervised aquatic facilities, calling into question the efficacy of the supervision chain. The aim of this research is to fully assess the periods during which supervision is not carried out, or carried out in an inadequate manner. The observations made in 108 French PSP show that constant supervision, as stipulated by regulations, represents only half of the time...

Triple-negative breast cancer does not express estrogen receptor-α, progesterone or the HER2 receptor making hormone or antibody therapy ineffective. Cisplatin may initiate p73-dependent apoptosis in p53 mutant cell lines through Fas trimerization and Caspase-8 activation and Bax up regulation and subsequent Caspase-9 activation. The triple-negative breast cancer, MDA-MB-231, overexpresses the protein Lifeguard, which inhibits Fas-mediated apoptosis by inhibiting Caspase-8 activation after Fas trimerization...

PURPOSE: The whole drowning process usually occurs within seconds to a few minutes. An early rescue may stop and/or prevent most medical complications. Fins, rescue tube, and rescue board (RB) are the equipment most frequently used by lifeguards. Our objective was to compare, in a water rescue quasiexperimental trial, these different pieces of rescue equipment to define the safest and with the lower rescue time as well as to assess their effects on the lifeguards' physiological state and cardiopulmonary resuscitation (CPR) performance...

INTRODUCTION: The strong physical demands that are required of lifeguards during rescues also require an accurate self-perception of one's fitness level to be able to regulate the intensity of effort. OBJECTIVES: The aim of this study was to determine the real aerobic capacity (RAC) and to compare it with two self-reported measurements: subjective appraisal of aerobic capacity (SAAC) and appraisal of physical exercise (APE). METHODS: Fifty-two professional lifeguards were included in the study...

Death receptors are members of the tumor necrosis factor receptor superfamily involved in the extrinsic apoptotic pathway. Lifeguard (LFG) is a death receptor antagonist mainly expressed in the nervous system that specifically blocks Fas ligand (FasL)-induced apoptosis. To investigate its mechanism of action, we studied its subcellular localization and its interaction with members of the Bcl-2 family proteins. We performed an analysis of LFG subcellular localization in murine cortical neurons and found that LFG localizes mainly to the ER and Golgi...

Anti-apoptotic protein Lifeguard (LFG) is upregulated on T cells upon in vitro activation. To investigate its role in T cell immunity we infected wild type and LFG knockout bone marrow chimaeras mice with LCMV. We observed a decreased number of LFG KO activated CD8 and CD4 T cells throughout the infection and a marked decrease in LFG KO LCMV specific memory T cells. WT and KO T cells proliferated at the same rate, however, LFG KO CD44(hi) T cells showed increased cell death during the initial phase of the immune response...

Lifeguard (LFG) is a transmembrane protein which is highly expressed in tissues of the hippocampus and the cerebellum, especially during postnatal development. This protein is responsible for the protection of neurons against Fas-induced apoptosis, and the same effect can be seen in tumor cells derived from mastocarcinoma. However, the molecular function of LFG and its regulation in the carcinogenesis of human breast cells remains to be elucidated. In the present study, we investigated the connection of the interaction of LFG within an array analysis of over 9,000 different proteins...
