The decline in muscle strength and muscle quality in relation to metabolic derangements in adult women with obesity

Background & aims: The metabolic and functional characteristics related to sarcopenic obesity have not been thoroughly explored in the earlier stages of the aging process. The aim of the present study was to examine the phenotype of sarcopenic obesity, in terms of lean body mass, muscle strength and quality, in adult women with and without the Metabolic Syndrome (MetS), and its relationship with the features of myosteatosis. Methods: Study participants were enrolled at the Sapienza University, Rome, Italy. Body composition was assessed by DXA. The Handgrip strength test (HGST) was performed. HGST was normalized to arm lean mass to indicate muscle quality; intermuscular adipose tissue (IMAT) and intramyocellular lipid content (IMCL) were measured by magnetic resonance imaging and spectroscopy, as indicators of myosteatosis. Different indices of sarcopenia were calculated, based on appendicular lean mass (ALM, kg) divided by height squared, or weight. The NCEP-ATPIII criteria were used to diagnose the MetS. HOMA-IR was calculated. The physical activity level (PAL) was assessed through the IPAQ questionnaire. Results: 54 women (age: 48 ± 14 years, BMI: 37.9 ± 5.4 kg/m 2 ) were included. 54% had the MetS (metabolically unhealthy, MUO). HGST/arm lean mass was lower in MUO women than women without the MetS (6.3 ± 1.8 vs. 7.8 ± 1.6, p = 0.03). No differences emerged in terms of absolute ALM (kg) or other indices of sarcopenia (ALM/h 2 or ALM/weight) between metabolically healthy (MHO) vs. MUO women (p > 0.05). Muscle quality was negatively associated with HOMA-IR (p = 0.02), after adjustment for age, body fat, hs-CRP levels, and PAL. IMAT, but not IMCL, was significantly higher in obese women with the MetS compared to women without the MetS (p > 0.05). No association emerged between HGST/arm lean mass and IMAT or IMCL when HOMA-IR was included in the models. Conclusion: Insulin resistance, and not sarcopenia or myosteatosis per se, was associated with muscle weakness, resulting in the phenotype of “dynapenic obesity” in middle-aged women with the metabolic syndrome

Two-dimensional kinematics in gait evaluation of Bardigiano Horse breeding stock

Kinematics studies the change of position of the body segments in space during a speci- fied time: motion is described quantitatively by linear and angular variables. The data are displayed graphi- cally. In this preliminary study the kinematics parameters at trot of an Italian horse breed are considered, in order to develop an objective method for gait analysis in field condition. Six Bardigiano mares were considered. Fourteen markers were glued on the left side of the standing mares at previously defined skel- etal reference points. The recordings were made using a video digital camera and analyzed using the SIMI Motion System. The obtained joint angle-time diagrams are similar to those found by other authors in other breeds. A horse showed an elbow motion diagram quite different from the others. The data were compared with judges scores. This study is a first step to obtain a reliable method for gait evaluation in this breed

Morphological evolution of Bardigiano horse

The Bardigiano horse is a local breed of the province of Parma. Since the institution of the Stud Book in 1977, the breed has improved its diffusion and is currently present with 110 stallions and over 1700 mares in 43 provinces in Italy and beyond that in Germany, Switzerland and Hungary

Energy consumption and analysis of industrial drying plants for fresh pasta process

The article presents results concerning the energy needs and the CO2 emissions resulting from the production process of a small factory (located in Molise region) producing fresh pasta. Two production processes are responsible for the most of energy demand. The pasteurisation and the drying processes are responsible for the 50% of the electricity consumption and the whole thermal energy. Therefore innovative solutions have been studied in order to limit the energy requirements and the CO2 emissions. Such solutions take into account the adoption of high-efficiency motors and heat recovery in the main processes

Strategy for the treatment and follow-up of sinonasal solitary extramedullary plasmacytoma: a case series

Extramedullary plasmacytoma is a rare neoplasm characterized by monoclonal proliferation of plasma cells outside bone marrow. It accounts for 4% of all non-epithelial sinonasal tumors. According to the literature, radiotherapy is the standard therapy for extramedullary plasmacytoma. However, the conversion rate of extramedullary plasmacytoma to multiple myeloma is reported to be between 11 and 33% over 10 years. The highest risk of conversion is reported during the first 2 years after diagnosis, but conversion has been noted up to 15 years after diagnosis. Once conversion to multiple myeloma is complete, less than 10% of patients will survive 10 years

Safety and comfort of domestic bortezomib injection in real-life experience

Despite novel agents, multiple myeloma is still an incurable disease, especially for elderly and frail patients, who are difficult to manage for concomitant comorbidities as the therapeutic options are limited and the response to chemotherapy is often short. We report our evaluations upon safety and efficacy of domestic subcutaneous bortezomib in elderly and frail patients candidate to bortezomib-melphalan-prednisone (VMP) regimen. We confirmed that overall incidence of adverse events, including peripheral neuropathy, was low, and in no case required admission to emergency service, contributing to reduce the rate of therapy discontinuation. These results confirm the effectiveness and safety of subcutaneous bortezomib, in a real-life-experience, and define a new possibility of safe auto-administration in a comfortable domestic setting. We suggest that domestic treatment can significantly improve the quality of life of the patients, avoiding unnecessary transfer to the hospital without reducing treatment efficacy

Pegfilgrastim in primary prophylaxis of febrile neutropenia following frontline bendamustine plus rituximab treatment in patients with indolent non-Hodgkin lymphoma: a single center, real-life experience

In this prospective study, the impact of granulocyte colony-stimulating factors (G-2 CSF) administered during induction treatment with bendamustine plus rituximab for indolent non- Hodgkin Llymphoma (NHL) was evaluated by comparing patients who received secondary prophylaxis with filgrastim (control group) versus. patients who received pegfilgrastim as primary prophylaxis (peg-group). The primary endpoint was the incidence rate of febrile neutropenia (FN)- related chemotherapy disruptions (regarding dose-dense and/or dose-intensity of schedule). The Ssecondary endpoint included days of hospitalization due to FN, and G-CSF-related side effects (grade ≥3 WHO toxicity criteria) in each group
