EFFECTS OF RUN TRAINING ON BONE DEVELOPMENT AND BONE MINERALIZATION IN GROWING MICE

We planned to study the body weights, bone sizes and bone mineral (Ca, Mg, Zn) contents of growing mice subjected to treadmill training. Twelve 4-week-old male Swiss Albino mice were divided into sedentary and exercise groups. The mice were trained by running exercise on a flat bed treadmill with 15 m/min, 30 min/day motion, throughout 5 days per week, for 12 weeks. The body weight of animals, and length, fat-free dry weight and Ca, Mg, and Zn contents of bones were measured in both groups. Body weights of animals, and lengths and wet and dry weights of the femur and the tibia were significantly higher in the exercised group. Also, the Zn, Mg and Ca mineral contents of bones in the group that underwent exercise were higher than in the other group. Running exercise with a flat bed treadmill performed by the growing mice is an effective exercise mode, especially for bone morphology

Knee Muscle Strength Recovery In The Early Period After Acl Reconstruction

Objectives: The aim of this study was to investigate quadriceps and hamstrings isometric strength at 4, 8 and 12 week time points following ACL Reconstruction (ACLR) and to document the strength changes of these muscles over time. The primary hypothesis was that there would be significant increases in quadriceps and hamstring muscle strengths between the 4th, 8th and 12th weeks following ACLR. The secondary hypothesis was that the quadriceps index would be higher than hamstring index at 12th week after ACLR. Methods: Thirty patients (Mean ± SD [age, 29.1±2.3yrs; weight, 77.3±13.2kg; height, 172.1±7.1cm; BMI, 21.2±3.5kg/m2, time to surgery: 7.1±7.2 months]) who underwent ACLR with Hamstring Tendon Autograft (HTG) were enrolled in this study. The isometric strength of quadriceps and hamstring muscles was measured on an isokinetic dynamometer at 60° knee flexion angle at 4th, 8th and 12th weeks after surgery. The recovery of quadriceps and hamstring muscles strength following rehabilitation was expressed as a Quadriceps Index (QI) and Hamstring Index (HI) and calculated with the following formula:[(maximum voluntary isometric torque of the involved limb / maximum voluntary isometric torque by uninvolved limb) × 100]. Torque output of the involved and uninvolved limbs and quadriceps and hamstring indexes were used for the statistical analysis. A repeated measures of ANOVA was used to determine the strength changes of quadriceps and hamstrings over time. Results: Quadriceps and Hamstrings strengths significantly increased over time for both involved (Quadriceps: F (2,46)=58.3, p0.05) or between the 8 and 12 week time points (p=0.07). Quadriceps and hamstring indexes significantly changed from 4th weeks (QI:57.9, HI:54.4 ) to 8th weeks (QI:78.8, HI:69.9 ) and from 8th weeks to 12th weeks (QI:82, HI:75.7 ) (p<0.001); however, there was no difference between indexes at the 12-week time point (p=0.17). Conclusion: Isometric strength of quadriceps and hamstring muscles for the involved and uninvolved limb increased during the early period of ACLR. The results of this study could be a baseline for clinicians while prescribing a rehabilitation protocol for ACLR patients with HTG to better appreciate expected strength changes of the muscles in the early phase.PubMe

La dosis única de instilación intravesical postoperatoria inmediata de quimioterapia no es superior al lavado continuo con suero

Introduction and objectives: To evaluate whether there is any difference between immediate postoperative instillation of intravesical chemotherapy (IPOIC) and continuous saline bladder irrigation(CSBI) in terms of bladder cancer(BC) recurrence in patients with primary low- or intermediate-risk non-muscle-invasive BC (NMIBC). Materials and methods: Medical records of 1482 patients who underwent transurethral resection of bladder tumor between March 1994 and August 2020 were reviewed retrospectively. Patients were divided into two groups according to IPOIC and/or CSBI administration status (Group 1: CSBI alone; Group 2: CSBI following IPOIC). Low- and intermediate-risk NMIBC patients were also divided into subgroups according to IPOIC and/or CSBI administration status. Results: A total of 594 patients with primary NMIBC were included. Of the patients, 86 (14.5%) were female and 508 (85.5%) were male with a median age of 69 (60-78) years. The frequency of patients in group 1 and group 2 were 361 (60.8%) and 233 (39.2%), respectively. Recurrent disease was observed in 213 (35.9%) patients. There was no difference between the groups when they were compared for recurrent disease frequency, median time to first recurrence and frequency of recurrence within first 12 months (P=.064, P=.671, and P=.145, respectively). Disease recurrence rates in low-risk NMIBC patients was lower when they were treated with “CSBI following IPOIC” when compared to “CSBI alone” (P=.042). However, no difference was observed in low-risk NMIBC subgroups when they were compared for pathological features of recurrent tumors such as number, size, grade, stage, and presence of carcinoma in situ (P>.05, for each). Conclusions: “CSBI following IPOIC” combination was not superior to “CSBI alone” for preventing adverse pathological outcomes in recurrent low- and intermediate-risk NMIBC. © 2022 AEUAgradecemos a Murat Bozlu MD, profesor del Departamento de Urología, Facultad de Medicina, Universidad de Mersin
