Isokinetic rotator muscles fatigue in glenohumeral joint instability before and after Latarjet surgery: a pilot prospective study.

We aimed to analyze the changes in isokinetic internal (IR) and external (ER) rotator muscles fatigue (a) in patients with non-operated recurrent anterior instability, and (b) before and after shoulder surgical stabilization with the Bristow-Latarjet procedure. Thirty-seven patients with non-operated unilateral recurrent anterior post-traumatic instability (NG) were compared with 12 healthy subjects [control group (CG)]. Twenty patients with operated recurrent anterior instability group (OG) underwent isokinetic evaluation before and 3, 6, and 21 months after Bristow-Latarjet surgery. IR and ER muscles strength was evaluated with Con-Trex® dynamometer, with subjects seated and at a 45° shoulder abduction angle in scapular plane. IR and ER muscle fatigue was determined after 10 concentric repetitions at 180° · s(-1) through the fatigue index, the percent decrease in performance (DP), and the slope of peak torque decrease. There were no differences in rotator muscles fatigue between NG and CG. In OG, 3 months post-surgery, IR DP of operated shoulder was significantly (P < 0.001) higher than presurgery and 6 and 21 months post-surgery. Rotator muscles fatigability was not associated with recurrent anterior instability. After surgical stabilization, there was a significantly higher IR fatigability in the operated shoulder 3 months post-surgery, followed by recovery evidenced 6 months post-surgery and long-term maintenance over 21 months.

Securin and separase modulate membrane traffic by affecting endosomal acidification.

Securin and separase play a key role in sister chromatid separation during anaphase. However, a growing body of evidence suggests that in addition to regulating chromosome segregation, securin and separase display functions implicated in membrane traffic in Caenorhabditis elegans and Drosophila. Here we show that in mammalian cells both securin and separase associate with membranes and that depletion of either protein causes robust swelling of the trans-Golgi network (TGN) along with the appearance of large endocytic vesicles in the perinuclear region. These changes are accompanied by diminished constitutive protein secretion as well as impaired receptor recycling and degradation. Unexpectedly, cells depleted of securin or separase display defective acidification of early endosomes and increased membrane recruitment of vacuolar (V-) ATPase complexes, mimicking the effect of the specific V-ATPase inhibitor Bafilomycin A1. Taken together, our findings identify a new functional role of securin and separase in the modulation of membrane traffic and protein secretion that implicates regulation of V-ATPase assembly and function.

Physical activity is inversely associated with high blood pressure independently of overweight in Brazilian adolescents.

The purpose of this study was to assess the relationship between blood pressure (BP) levels and physical activity (PA) domains accounting for overweight/obesity. Adolescents aged 10 to 17 years old were recruited (n = 1021). International Obesity Task Force (IOTF) criteria were used to define overweight and obesity. High BP was defined using the Center of Disease Control and Prevention criteria. Different domains of PA (school activities, sport out of school, and leisure time PA) were assessed using a validated questionnaire. The prevalence of overweight/obesity was 21.9% for boys and 14.8% for girls. Some 13.4% of boys and 10.2% of girls, respectively, had high blood pressure (HBP). A strong and positive association was found between overweight and HBP. After adjustment for body mass index (BMI), total PA was inversely associated with BP. When all PA domains were entered simultaneously in a regression model, and after adjustment for BMI, only sport out of school was significantly and inversely associated with systolic BP [β: -0.82 (-1.50; -0.13)]. These findings open avenue for the early prevention of HBP by the prevention of obesity and promotion of PA.

Molecular mechanism of myosin Va recruitment to dense core secretory granules.

The brain-spliced isoform of Myosin Va (BR-MyoVa) plays an important role in the transport of dense core secretory granules (SGs) to the plasma membrane in hormone and neuropeptide-producing cells. The molecular composition of the protein complex that recruits BR-MyoVa to SGs and regulates its function has not been identified to date. We have identified interaction between SG-associated proteins granuphilin-a/b (Gran-a/b), BR-MyoVa and Rab27a, a member of the Rab family of GTPases. Gran-a/b-BR-MyoVa interaction is direct, involves regions downstream of the Rab27-binding domain, and the C-terminal part of Gran-a determines exon specificity. MyoVa and Gran-a/b are partially colocalised on SGs and disruption of Gran-a/b-BR-MyoVa binding results in a perinuclear accumulation of SGs which augments nutrient-stimulated hormone secretion in pancreatic beta-cells. These results indicate the existence of at least another binding partner of BR-MyoVa that was identified as rabphilin-3A (Rph-3A). BR-MyoVa-Rph-3A interaction is also direct and enhanced when secretion is activated. The BR-MyoVa-Rph-3A and BR-MyoVa-Gran-a/b complexes are linked to a different subset of SGs, and simultaneous inhibition of these complexes nearly completely blocks stimulated hormone release. This study demonstrates that multiple binding partners of BR-MyoVa regulate SG transport, and this molecular mechanism is universally used by neuronal, endocrine and neuroendocrine cells.

Cost effectiveness of a new combined immunosuppressive and antiviral regimen on the one-year follow-up of kidney transplant patients.

Background: Medical prescription after organ transplant must prevent both rejection and infectious complications. We assessed the 1-year effectiveness and cost of introducing a new combined regimen in kidney transplantation. Methods: Patients transplanted from January 2000 to March 2003 (Period 1) were compared to patients transplanted from April 2003 to July 2005 (Period 2). In period 1, patients were treated with Basiliximab, Cyclosporin, steroids and Mycophenolate (MMF) or Azathioprine. Prophylaxis with Valacyclovir was prescribed only in CMV D+/R- patients. In period 2, immunosuppressive drugs were Basiliximab, Tacrolimus, steroids and MMF. A 3-month universal CMV prophylaxis with Valganciclovir was used. Medical charts of outpatient visits allowed identifying drug, laboratory and radiological tests use, and hospital information system causes of hospitalisation and length of stay (LOS) over the first year after transplant. Patients with incomplete costs data were excluded. Results: 53 patients were analysed in period 1, and 60 in period 2. CMV serostatus patterns were not significantly different between the 2 periods. Over 12 months, acute rejection decreased from 22 patients (42%) in period 1 to 4 patients (7%) in period 2 (p<0.001), and CMV infection from 25 patients (47%) to 9 patients (15%, p<0.001). Average total rehospitalisation LOS decreased from 28±19 to 20±11 days (p<0.007). Average outpatient visits decreased from 49±10 to 39±8 (p<0.001). Average immunosuppression and CMV prophylaxis costs increased from US$ 18,362±6,546 to 24,637±5,457 (p<0.001), while average graft rejection costs decreased form US$ 4,135±9,164 to 585±2,850 (p=0.005), and average CMV treatment costs from US$ 2,043±5,545 to 91±293 (p=0.008). Average outpatient visits costs decreased from US$ 7,619±1,549 to 6,074±1,043 (p<0.001), and other hospital costs from US$ 3,801±6,519 to 1,196±3,146 (p=0.007). Altogether, average 1-year treatment costs decreased from US$ 35,961±14,916 to 32,584±6,211 (p=0.115). Cost-effectiveness ratios to avoid graft rejection and CMV infection decreased from US$ 61,482±9,292 to 34,911± 1,639 (p=0.006) and US$ 68,070±11,122 to 39,899±2,650 (p=0.015), respectively. Conclusion: The new combined regimen administered in period 2 was significantly more effective. Its additional cost was more than offset by savings linked with complications avoidance.
