RESUMO
OBJECTIVE: Osteoporosis is a chronic metabolic syndrome associated with debilitating consequences that represents one of the major non-communicable diseases and the most common bone illness that affects both men and women. This observational study evaluates the amount of physical activity and the nutritional intake in a group of postmenopausal women who have a sedentary job. PATIENTS AND METHODS: All subjects underwent a medical evaluation, a body impedance analysis to evaluate body composition (fat mass, fat-free mass, and body cell mass), and a dual-energy X-ray absorptiometry to analyze bone mineral density. Additionally, a 3-day food record questionnaire and the International Physical Activity Questionnaire were administered respectively to evaluate patients' foods and beverages assumptions and the participants' Physical Activity levels. RESULTS: The study showed that most of the patients had a moderate activity level and inadequate calcium and vitamin D assumption compared to guidelines. CONCLUSIONS: The onset of osteoporosis seemed to be reduced at higher levels of leisure time, domestic, and transport activities, even in subjects who have a sedentary job and insufficient assumption of micronutrients.

Chronic degenerative non-communicable diseases (CDNCDs), in particular chronic kidney disease, induce gut microbiota (GM) dysbiosis, which, in turn, worsens the progression of CDNCDs and patients' quality of life. We analyzed literature studies to discuss the possible positive and beneficial impact of physical activity on GM composition and CV risk in CKD patients. Regular physical activity seems to be able to positively modulate the GM, reducing the systemic inflammation and consequently the production of uremic gut-derived toxins, which are directly correlated with the increase of cardiovascular risk. In particular, the accumulation of indoxyl sulphate (IS) seems to be able to induce vascular calcifications, vascular stiffness and cardiac calcifications, while p-Cresyl sulphate (p-CS) seems to be able to exert a cardiotoxic action through metabolic pathways, capable of inducing oxidative stress. In addition, trimethylamine N-oxide (TMAO) can alter lipid metabolism, inducing the production of foam cells and causing an accelerated atherosclerosis process. In this context, a regular physical activity program seems to represent an adjuvant non-pharmacological approach to the clinical management of CKD patients.

OBJECTIVES: The aim of the study was to evaluate the effects of a combined aerobic and strength program on physiological and psychological parameters in female breast cancer survivors. STUDY DESIGN: Randomised controlled trial. METHODS: 20 patients (age: 45.6 ± 2.7 yrs) surgically treated for breast cancer that had completed all cancer therapies at least 6 months before and with no contraindications to physical activity, were recruited and randomly assigned to an intervention group (n = 10) and a control group (n = 10). Intervention group patients attend to a 24-week combined aerobic and strength training program. Physiological (i.e. VO2max, bioelectrical impedance test, maximal strength of principal muscular groups) and psychological (i.e. functional assessment of chronic illness therapy-fatigue: FACIT-F) parameters were assessed at baseline and after 24 weeks. RESULTS: After 24 weeks the intervention group showed significant improvement in VO2max (38.8%), strength of upper and lower limbs (ranging from 13 to 60%) and decrease in fat mass percentage (-6.3%). The FACIT-F showed significant increase in all of the three scores that can be derived (FACIT-F Trial outcome: 13%; FACT-G total score: 18%; FACIT-F total score: 15%) showing patient's quality of life (QOL) improvement. No significant change in all the parameters was found for the control group. CONCLUSION: These results show the positive effects of a combined aerobic and strength training program on breast cancer survivors and underline the importance of the early inclusion of structured physical activity in the rehabilitation protocol.

Small cell carcinoma of the urinary bladder (SCCUB) is a rare variant of neuroendocrine nonepithelial tumor. Clinically, SCCUB appears like a flat or ulcerated lesion and microscopically can cause microvascular invasion and necrosis. Small cell cancer, rarely found in the urogenital tract in a primitive form, usually coexists with urothelial bladder cancers. It has an incidence of 0.35-0.7% of all bladder neoplasms and survival at 5 years is estimated to be around 8%. A 60-year-old man who was a smoker was referred to our department with episodes of gross hematuria and pain in the lumbar region. After an extensive transurethral resection of the bladder, including of the muscular layer, the diagnosis of small cell carcinoma of the bladder was made. The neoplastic cells were positive with immunohistochemical staining for chromogranin A, paranuclear reactivity to cytokeratin and neuron-specific enolase. A total-body CT scan revealed lymph node involvement and hepatic, adrenal and lung metastases. Because of the advanced stage it was decided to avoid radical cystectomy and perform chemotherapy. The patient underwent two different cycles of cisplatin chemotherapy following international recommendations, but unfortunately without any response. After palliative therapy, the patient died in January 2010.

AIM: Rhodiola Rosea, is an adaptogen plant which has been reported to promote fatty acids utilisation, to ameliorate antioxidant function, and to improve body resistance to physical strenuous efforts. The purpose of the present study was to investigate the effects on physical performance as well as on the redox status of a chronic Rhodiola Rosea supplementation in a group of competitive athletes during endurance exercise. METHODS: Following a chronic supplementation with Rhodiola Rosea for 4 weeks, 14 trained male athletes underwent a cardio-pulmonary exhaustion test and blood samples to evaluate their antioxidant status and other biochemical parameters. These data were compared with those coming from the same athletes after an intake of placebo. RESULTS: The evaluation of physical performance parameters showed that HR Max, Borg Scale level, VO(2) max and duration of the test were essentially unaffected by Rhodiola Rosea assumption. On the contrary, Rhodiola Rosea intake reduced, in a statistically significative manner, plasma free fatty acids levels. No effect on blood glucose was found. Blood antioxidant status and inflammatory parameters resulted unaffected by Rhodiola Rosea supplementation. Blood lactate and plasma creatine kinase levels were found significantly lower (P<0.05) in Rhodiola Rosea treated subjects when compared to the placebo treated group. CONCLUSION: Chronic Rhodiola Rosea supplementation is able to reduce both lactate levels and parameters of skeletal muscle damage after an exhaustive exercise session. Moreover this supplementation seems to ameliorate fatty acid consumption. Taken together those observation confirm that Rhodiola Rosea may increase the adaptogen ability to physical exercise.

AIM: This study examined the functional differences existing in the trunk flexion-extension movement in standing and seated positions during isokinetic exercises, as well as the influence of position on overload of the lumbar column. METHODS: Nine females underwent an isokinetic test at 60 and 180 degrees /s in standing and seated positions. Muscle electrical activity was assessed by means of surface electromyography (EMG). Motion angles related to the different body segments were extrapolated from video images. RESULTS: The range of motion for hip movements was statistically significantly higher in the standing position, whereas it was similar for all the other segments studied in both positions. During the first phases of the movement, the lumbar tract showed a more marked lordosis in standing position. Peak torque values were significantly higher for flexion in standing position. Surface EMG showed significant differences in both positions only for the gluteal and biceps femoris muscles. CONCLUSION: The seated position allowed made it possible to limit the involvement of the hip muscles, particularly the iliopsoas during flexion, whereas there was little contribution to the trunk extension from hip extensor muscles. In addition, trunk extensors/flexors ratio showed values variable with velocity in standing position. Therefore, if the participation of accessory muscles is avoided, the seated position allows us to more accurately assess these two groups of antagonist muscles, whose balanced ratio is essential in the prevention of spine pathologies. The seated position has also been found to be more suitable in order to limit functional overload of the lumbar column.

The Authors show an operation of urological surgery, unusual in relation to the rather limited indications. The operation of hemitrigonectomy, although it is framed in the chapter of the partial resections of bladder, does not get an exact identity in literature; yet, it is peculiar for both technical problems and some basic expedients sheltering surgeons from various complications. Hemitrigonectomy, performed by the Authors in six cases in the last 3 years, supplied excellent anatomic and functional results, and was burdened by no relevant complications.
