To estimate the effect of obesity on type 2 diabetes (T2DM) risk and evaluate to what extent non-alcoholic fatty liver disease (NAFLD) mediates this association.

Data came from 4,522 adults ages 45-84 participating in the Multi-Ethnic Study of Atherosclerosis cohort. Baseline obesity was defined using established BMI categories. NAFLD was measured by CT scans at baseline and incident T2DM defined as fasting glucose ≥126mg/dL or use of diabetes medications.

Over a median 9.1 years of follow-up between 2000 and 2012, 557 new cases of T2DM occurred. After adjusting for age, sex, race/ethnicity, education, diet and exercise, those with obesity had 4.5 times the risk of T2DM compared to normal weight (hazard ratio [HR]=4.5, 95% confidence interval [CI] 3.0, 5.9). The mediation analysis suggested that NAFLD accounted for ~36% (95% CI 27, 44) of the effect (direct effect HR=3.2, 95% CI 2.3, 4.6; indirect effect through NAFLD, HR=1.4, 95% CI 1.3, 1.5).

These data suggest that the association between obesity and T2DM risk is partially explained by the presence of NAFLD. selleck kinase inhibitor Future studies should evaluate if NAFLD could be an effective target to reduce the effect of obesity on T2DM.

Hemiarthroplasties cause damage to the cartilage that they articulate against, which is a major limitation to their use. This study investigates the use of lower stiffness materials to determine if they improve hemiarthroplasty contact mechanics and thus reduce the risk of cartilage damage.

Eleven fresh-frozen cadaveric upper extremities were disarticulated and fixed in a custom-built jig that applied a static load of 50 N to the radiocapitellar joint. Flexion angles of 0°, 45°, 90° and 135° were tested with radial head implants made of cobalt-chrome (CoCr) and ultra-high weight molecular-polyethylene (UHMWPE), compared to the native radial head. A Tekscan thin-film sensor was used to measure the contact area and contact pressure between the radius and capitellum.

UHMWPE and CoCr are too stiff in the application of hemiarthroplasty resulting in lower contact areas and higher contact pressures relative to the native joint. The native contact area was on average 42±20 mm
larger than UHMWPE (p<0.001), and 55±24 mm
larger than CoCr (p<0.001). UHMWPE had a contact area 13±10 mm
greater than CoCr (p=0.014).

This study shows that even though UHMWPE has a stiffness several times lower than CoCr, the use of this material in hemiarthroplasty lead to only a minor improvement in contact mechanics. Neither implant restored contact similar to the native articulation.

Investigation into new materials to improve the contact mechanics of hemiarthroplasty should focus on materials with a lower stiffness than UHMWPE.

While reverse shoulder arthroplasty has shown satisfactory outcomes in rotator cuff deficient shoulders, its performance in shoulders with an intact rotator cuff has not been fully elucidated. Shoulder osteoarthritis can present with alterations in glenoid morphology which have contributed to inconsistent outcomes in anatomic shoulder replacement. A predominance of these arthroplasty complications is due to the glenoid component. Given these glenoid related difficulties, RSA may provide a more favorable option. We aimed to summarize the current literature for rotator cuff intact osteoarthritis treated with primary reverse shoulder arthroplasty and to determine whether morphological changes in the glenoid led to inferior outcomes.

A literature search was performed which utilized an inclusion criteria of primary reverse shoulder arthroplasty for osteoarthritis with intact rotator cuff. Modified Coleman Methodology Score was calculated to analyze reporting quality. Following appropriate exclusions, 13 studietroversion, posterior humeral subluxation and glenoid bone loss. The attributes of reverse arthroplasty which contribute to favorable outcomes in arthritic shoulders include its semi constrained design and its robust glenoid fixation. Soft tissue imbalances as a consequence of pathologic glenoid morphology and chronic humeral subluxation can be mitigated with the RSA semi constrained design. Glenoid bone loss can be effectively managed with reverse's robust glenoid fixation, with and without the use of bone graft. The capability to lateralize the joint center of rotation may be valuable when faced with a medialized glenoid wear pattern. The current findings suggest that reverse arthroplasty can achieve highly favorable outcomes for glenohumeral osteoarthritis with intact rotator cuff.
Epilepsy is a disorder characterized by recurrent seizures that affects 1% of the population. However, the neurochemical alterations observed in epilepsy are not fully understood. There are different animal models of epilepsy, such as genetic or drug induced. In the present study, we utilize Wistar Audiogenic Rats (WAR), a murine strain that develops seizures in response to high intensity audio stimulation, in order to investigate abnormalities in glutamatergic and GABAergic systems.

Synaptosomes and glial plasmalemmal vesicles were prepared from hippocampus and cortex, respectively. Glutamate and GABA release and uptake were assayed by monitoring the fluorescence and using L-[
H]-radiolabeled compounds. Glutamate and calcium concentration in the synaptosomes were also measured. The expression of neuronal calcium sensor 1 (NCS-1) was determined by western blot.

Glutamate and GABA release evoked by KCl was decreased in WAR compared to control Wistar rats. Calcium independent release was not considerably different in both groups.
