Rugby Sevens, a new Olympic sport, features high intensity intermittent running and contact efforts over short match durations, normally six times across two to three days in a tournament format. Elite Rugby Sevens seasons often include over a dozen competitive tournaments across less than nine months, demanding deliberate and careful training-stress balance and workload management alongside development of the necessary physical qualities required for competition. Focus on running and repeated power skills, strength, and match-specific conditioning capacities is advised...

REVIEW
M Bestue-Cardiel, D Natera-de Benito
Since Engel reported the first case of congenital myasthenia in 1977 and the first pathogenic gene was found in 1995, knowledge about congenital myasthenic syndromes has continued to grow. Over the years, the pathogenic basis, its clinical features, the phenotype-genotype correlations that have been established and its therapeutic management have all been described. In this group of diseases the safety margin of neuromuscular transmission is altered by different mechanisms: in the synthesis or storage of acetylcholine quanta in the synaptic vesicles, in the calcium-mediated release of acetylcholine in the nerve terminal or in the efficiency of the quantum released to generate a post-synaptic depolarisation...

This description shows the histological findings of a peroneus brevis tendon allograft used for labral reconstruction, implanted 8 weeks before being retrieved due to a postoperative complication unrelated to the graft. As far as we have knowledge this is the first description about revascularization of an allograft used for hip labral reconstruction. The histological report of the removed peroneus brevis tendon allograft shows evidence of vascular ingrowth represented by small vessels with a thin muscular wall in all layers of the graft and cellular migration mainly represented by mature fibroblasts...

Combination therapy including colistin and a carbapenem has been found to be associated with lower mortality in the treatment of bloodstream infections (BSI) due to KPC-producing Klebsiella pneumoniae when the isolates show a meropenem or imipenem MIC of <16 mg/liter. However, the optimal treatment of BSI caused by colistin- and high-level carbapenem-resistant KPC-producing K. pneumoniae is unknown. A prospective cohort study including episodes of bacteremia caused by colistin-resistant and high-level meropenem-resistant (MIC ≥ 64 mg/liter) KPC-producing K...

Zingiberaceae plants, commonly known as gingers, have been popular for their medicinal and culinary uses since time immemorial. In spite of their numerous health-promoting applications, many Zingiberaceae plants still receive no scientific attention. Moreover, existing reports mostly focused only on the Zingiberaceae rhizomes. Here, untargeted metabolite profiling using Gas Chromatography - Mass Spectrometry (GC-MS) was used to compare the metabolic composition of leaves and rhizomes of the more common gingers, Zingiber officinale Rosc...

REVIEW
Luis Natera Cisneros, Juan Sarasquete Reiriz
The acromioclavicular joint represents the link between the clavicle and the scapula, which is responsible for the synchronized dynamic of the shoulder girdle. Chronic acromioclavicular joint instability involves changes in the orientation of the scapula, which provokes cinematic alterations that might result in chronic pain. Several surgical strategies for the management of patients with chronic and symptomatic acromioclavicular joint instability have been described. The range of possibilities includes anatomical and non-anatomical techniques, open and arthroscopy-assisted procedures, and biological and synthetic grafts...

Many of the described labral-reconstruction procedures are purely arthroscopic. This approach only allows segmentary reconstructions. For more extensive reconstructions, surgical dislocation of the hip still represents the more suitable approach. We present an arthroscopy-assisted procedure combined with an anterior mini-open approach, which could be considered for reconstruction of nonrepairable labral lesions located in the posterior aspect of the acetabulum and massive reconstructions in cases of global-pincer femoroacetabular impingement and protrusio acetabuli...

Recent research has documented crack cocaine's increasing spread in Mexico, which is likely to contribute to the rapid transmission of HIV and other sexually transmitted infections (STIs). In Mexico, crack use is increasing most rapidly in vulnerable, hard-to-reach populations, where little is known about risk behaviors. This report aims to present baseline data regarding HIV and STI knowledge and testing prevalence from an innovative projection mapping HIV intervention, in which 3-D illusions, animation, and visual text graphics and sound are projected onto buildings with health messages that were designed to disrupt everyday life and connect with the target population...
