The Influence of Varying Hip Angle and Pelvis Position on Muscle Recruitment Patterns of the Hip Abductor Muscles During the Clam Exercise
Authors: Willcox Emma L. , Burden Adrian M. 
Published: March 2013

Study Design Within-subject, repeated-measures design. Objectives To determine the influence of pelvis position and hip angle on activation of the hip abductors while performing the clam exercise. Background Therapeutic exercises are regularly employed to strengthen the hip abductors to improve lower-limb and pelvis stability. While previous studies primarily have compared the activity of hip abductor muscles between various exercises, few studies have examined the influence of varying the techniques of particular exercises on the relative activation of hip abductor muscles. Such information could be used to facilitate appropriate exercise instruction. Methods Muscle activation in 17 healthy, asymptomatic volunteers during 6 variations of the clam exercise was analyzed with surface electromyography. Electromyographic signals were recorded from the gluteus maximus, gluteus medius, and tensor fasciae latae. Normalized data were examined using 2-way, repeated-measures analyses of variance. Results The magnitude of gluteus maximus and gluteus medius activation was significantly greater when the pelvis was in neutral rather than reclined. Furthermore, gluteus medius activation was greatest when the hip was flexed to 60°. Activation of the tensor fasciae latae was not influenced by pelvis position or hip angle. Conclusion A neutral pelvis position is advocated to optimize recruitment of the gluteus maximus and gluteus medius during the clam exercise. Increasing the hip flexion angle increases activation of the gluteus medius. Tensor fasciae latae activity was relatively low and generally unaffected by variations of the clam exercise.

Published: March 2013

Study Design Randomized, double-blind, parallel-group clinical trial. Objectives To assess differences between a progressive agility and trunk stabilization rehabilitation program and a progressive running and eccentric strengthening rehabilitation program in recovery characteristics following an acute hamstring injury, as measured via physical examination and magnetic resonance imaging (MRI). Background Determining the type of rehabilitation program that most effectively promotes muscle and functional recovery is essential to minimize reinjury risk and to optimize athlete performance. Methods Individuals who sustained a recent hamstring strain injury were randomly assigned to 1 of 2 rehabilitation programs: (1) progressive agility and trunk stabilization or (2) progressive running and eccentric strengthening. MRI and physical examinations were conducted before and after completion of rehabilitation. Results Thirty-one subjects were enrolled, 29 began rehabilitation, and 25 completed rehabilitation. There were few differences in clinical or morphological outcome measures between rehabilitation groups across time, and reinjury rates were low for both rehabilitation groups after return to sport (4 of 29 subjects had reinjuries). Greater craniocaudal length of injury, as measured on MRI before the start of rehabilitation, was positively correlated with longer return-to-sport time. At the time of return to sport, although all subjects showed a near-complete resolution of pain and return of muscle strength, no subject showed complete resolution of injury as assessed on MRI. Conclusion The 2 rehabilitation programs employed in this study yielded similar results with respect to hamstring muscle recovery and function at the time of return to sport. Evidence of continuing muscular healing is present after completion of rehabilitation, despite the appearance of normal physical strength and function on clinical examination.

Published: March 2013

Study Design Double-blind, randomized controlled trial. Objective To examine the effectiveness of a manual therapy and exercise approach relative to a placebo intervention in individuals with carpometacarpal (CMC) joint osteoarthritis (OA). Background Recent studies have reported the outcomes of exercise, joint mobilization, and neural mobilization interventions used in isolation in patients with CMC joint OA. However, it is not known if using a combination of these interventions as a multimodal approach to treatment would further improve outcomes in this patient population. Methods Sixty patients, 90% female (mean ± SD age, 82 ± 6 years), with CMC joint OA were randomly assigned to receive a multimodal manual treatment approach that included joint mobilization, neural mobilization, and exercise, or a sham intervention, for 12 sessions over 4 weeks. The primary outcome measure was pain. Secondary outcome measures included pressure pain threshold over the first CMC joint, scaphoid, and hamate, as well as pinch and strength measurements. All outcome measures were collected at baseline, immediately following the intervention, and at 1 and 2 months following the end of the intervention. Mixed-model analyses of variance were used to examine the effects of the interventions on each outcome, with group as the between-subject variable and time as the within-subject variable. Results The mixed-model analysis of variance revealed a group-by-time interaction (F = 47.58, P<.001) for pain intensity, with the patients receiving the multimodal intervention experiencing a greater reduction in pain compared to those receiving the placebo intervention at the end of the intervention, as well as at 1 and 2 months after the intervention (P<.001; all group differences greater than 3.0 cm, which is greater than the minimal clinically important difference of 2.0 cm). A significant group-by-time interaction (F = 3.19, P = .025) was found for pressure pain threshold over the hamate bone immediately after the intervention; however, the interaction was no longer significant at 1 and 2 months postintervention. Conclusion This clinical trial provides evidence that a combination of joint mobilization, neural mobilization, and exercise is more beneficial in treating pain than a sham intervention in patients with CMC joint OA. However, the treatment approach has limited value in improving pressure pain thresholds, as well as pinch and grip strength. Future studies should include several therapists, a measure of function, and long-term outcomes. Trial registration: Current Controlled Trials ISRCTN37143779. Level of Evidence Therapy, level 1b.

Published: March 2013

Since its introduction in 1977, Percutaneous Coronary Interventions (PCI) is an important tool in the treatment of coronary artery disease (CAD). It is a retrospective analysis of data of 100 cases (132 vessels). The mean age was 50.9 years (range 30-70) with 90 (90%) male and 10 (10%) female. Indication of PCI includes acute and old MI, Chronic stable angina and unstable angina were 48 (48%), 33 (33%) and 19(19%) respectively. Procedure done in total 132 vessels among 100 patients. most of the cases were single vessels disease (SVD) {68 (68%} followed by double vessel disease (DVD) {30(30%)} , triple vessel disease (TVD) {02 (02%)} and chronic total occlusion (CTO) {02 (02%)}.Cobalt chromium was commonly used stent (117 (88.6%) followed by drug illuting stent (DES) 12 (9.1%) and bare metal stent (BMS) 3 (2.3%). Among the site of the stent insertion left anterior descending (LAD) 62 (47%), right coronary lesion (RCA) 37 (28), left circumplex artery (LCX) 33 (25%).Maximum stent length was 35 mm, minimum 10mm. Maximum stent diameter was 3.5 mm whereas minimum diameter 2.5 mm. The mean pretreatment reference diameter was 2.55 ± 0.20 mm and post treatment diameter 2.70 ± 0.45 mm. Angiographic, procedural and clinical success rate were 100%, 98% and 98% respectively. Major adverse cardiovascular event (MACE) {periprocedural MI} occurred in 2 (02 %) cases. Minor cardiovascular complications revealed vascular haematoma 2 (02%), bleeding from access site in 1 (01%), transient ventricular fibrillation (VF) in 3 (03%) cases. There was no hospital death, emergency CABG before discharge from hospital. Angiographic, procedural and clinical success rate were excellent with a little MACE and event free survival within 30 days follow up. So, PCI is a safe and effective method of myocardial revascularization irrespective of lesion morphology and type of stents used at immediate and 30 days follow up.

Published: March 2013

Adequate nutritional support may prevent weight loss following severe burn injury. However, persistently low levels of serum albumin, transferring and serum total protein in burn patients have suggested that a protein deficiency may continue to exist which is out of proportion to energy requirements. This interventional study cross sectional study was done in the Department of Biochemistry, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh during January 2008 to December 2008. A total of 40 acute burn injury (within 24 hours of burn) patients of 20-45 years age with 15%-30% burn were selected for this study as case. The study subjects were divided into two groups: Group I represent superficial burn & Group II represents deep burn. The mean age of 28.35±6.81 years and 30.85±7.32 years in group I and group II respectively. The number of male in Group-I was 08 and Group-II was 08 and male female ratio was 2:3. The mean serum total protein before infusion of amino acid in Group-I was 55.31±3.58 g/L and in Group-II was 52.01±2.26 g/L (p<0.001). The mean serum total protein after infusion of amino acid in Group-I was 68.02±2.04 g/L and in Group-II was 61.86±2.49g/L (p<0.001). The mean serum albumin before infusion of amino acid in Group-I was 27.6±2.88 g/L and in Group-II was 25.57±1.89 g/L (p<0.001). The mean serum albumin after infusion of amino acid in Group-I was 22.29±3.50 g/L and in Group-II was 19.83±2.86 g/L (p<0.001). In group-I, serum total protein was increased by 22.98% after infusion and in group-II, that was increased by 18.94% (p<0.01). In group-I, serum albumin was decreased by 19.24% after infusion and in group-II, that was decreased by 22.45% (p<0.05). Serum total protein significantly increased after infusion of amino acid but serum albumin significantly decreased after infusion of amino acid.

Published: March 2013

SummaryT stage was redefined for patients with differentiated thyroid carcinoma (DTC) between the 5th and 7th versions of the UICC tumour classification system. Patients, methods: 636 patients (486 women, 150 men; mean age 49.1 ± 15.6 years, mean follow-up 4.6 years) who had been treated with ablative radioiodine therapy after thyroidectomy for papillary (PTC) or follicular thyroid carcinomas (FTC) were retrospectively assessed on occurrence of locoregional recurrent disease, or cervical lymph node or distant metastases. Disease-free survival was calculated from initial T stage, classified according to both versions of the UICC staging system and compared with the prognostic value of primary tumour size. Kaplan-Meier method and two measures of explained variation, (1) R2 based on the (partial) likelihood ratio statistic of the Cox proportional hazards model and (2) a model-free variant of a distance measure proposed by Schemper had the aim to detect the most advantageous classification. Results: Of the 508 patients with PTC, 11 (2.2%) developed a local recurrence, 37 (7.3%) cervical lymph node and 23 (4.5%) distant metastases, 3 (2.3%), 8 (6.3%), and 18 (14.1%) were the numbers for the 128 FTC patients respectively. The two classification systems yielded an equal count of statistically significant differences regarding disease-free survival in patients with PTC while UICC 7th classification appeared slightly advantageous in patients with FTC. Regarding explained variation the UICC 7th classification tended to be superior to the UICC 5th classification, both in PTC and FTC, however statistical significance was not reached. Conclusion: The primary tumour size significantly added to the prognosis regarding local cervical and distant metastases.

Published: March 2013

• Premise of the study: Investigations of inflorescence architecture offer insight into the evolution of an astounding array of reproductive shoot systems in the angiosperms, as well as the potential to genetically manipulate these branching patterns to improve crop yield and enhance the aesthetics of horticultural species. The diversity of inflorescences in the economically important family Oleaceae was studied from a comparative developmental point of view for the first time, based on species of seven genera (Chionanthus, Fontanesia, Fraxinus, Jasminum, Ligustrum, Olea, Syringa).• Methods: Series of developmental stages of chemically fixed inflorescences were studied with epi‐illumination light microscopy.• Key results: All taxa studied have inflorescences with terminal flowers. The inflorescences are mostly panicles, but in some cases thyrsoids or compound botryoids. Phyllotaxis of the flower‐subtending bracts is mostly decussate, rarely tricussate (Fraxinus) or spiral (Jasminum). Accessory flowers or accessory inflorescences, almost unknown in Oleaceae as yet, were found in two genera. In Syringa, common bract‐flower primordia are formed by a delay in early bract development compared to flower development. Such a delay is also expressed by the loss of bracts in the distal part of inflorescence branches in Syringa and Chionanthus.• Conclusions: Significant variation in branching pattern and phyllotaxy was observed among the studied species of Oleaceae. The suppression of bracts and formation of accessory flowers were found as special features of inflorescence ontogeny. The occurrence of accessory flowers and accessory partial inflorescences is interesting from the point of view of dense and flower‐rich inflorescences in ornamental species.
Exposure and risk assessment of Staphylococcus aureus in food chain in Slovakia
Authors: Valí­k Ľubomí­r , Medveďová Alžbeta 
Published: March 2013

Foods can been contaminated by S. aureus usually as a result of unhygienic behaviour of staff or improper conducted technological procedures. Compared to saprophytic bacteria, S. aureus does not possess significant competitive properties; however its epidemiological potential consists in multiplication to density higher than 106 cfu/g and formation of heat-resistant enterotoxins by which it causes food poisoning. Based on the data in 2001, the risk was characterized as follows: S. aureus is almost ubiquitous in ewes’ milk. It is likely that it can increase its numbers by more than 3 log cfu/g and exceed the densities from 105-106 cfu/g for a short period, particularly at farm conditions. It is unlikely that it can succeed in competition with active lactic acid bacteria when they are present in higher numbers in ewes’ milk. While exposure of S. aureus through consumption of lump ewes’ cheese made ​​from raw milk is high, its consequences are mild and severity may be assessed as negligible. The overall risk is considered as low. A kind of confirmation provides the official incidence of staphylococcal poisoning which is 0.2 per 100,000 populations (lower than the EU average of 0.6/100,000).

Modelling of Bacillus cereus distribution, using data from pasteurized milk produced in Slovakia, at the time of consumption was performed in this study. The Modular Process Risk Model (MPRM) methodology was applied to over all the consecutive steps in the food chain. The main factors involved in the risk of being exposed to unacceptable levels of B. cereus (model output) were the initial density of B. cereus after milk pasteurization, storage temperatures and times (model input). Monte Carlo simulations were used for probability calculation of B. cereus density. By applying the sensitivity analysis influence of the input factors and their threshold values on the final count of B. cereus were determined. The results of the general case exposure assessment indicated that almost 14 % of Tetra Brik cartons can contain > 104 cfu/ml of B. cereus at the temperature distribution taken into account and time of pasteurized milk consumption.

The aim of this study was to determine the effect of dietary probiotics Bacillus subtilis (PB6) on egg weigh, egg mass weigh, egg fat content and cholesterol content in egg yolk in laying hens ISA Brown during two experiments. The probiotics where supplied to the laying hens for 42 days as preparation period before eggs samples collection. The eggs samples were collected during 6 days for the 1st and 2nd experiments after the hens reached the age of 34 and 61 weeks, respectively. A total of 36 ISA Brown laying hens were divided into 2 treatment groups. Control group laying hens were fed a basal diet with no probiotic added. In group Bacillus subtilis, the basal diet was supplemented with the bacteria Bacillus subtilis (PB6) at 1 g/kg, min. 2.3*108 cfu/g. Dietary treatments did not significantly affect the egg weigh, internal egg content weigh, cholesterol content expressed by g/100 g of egg yolk. Bacillus subtilis (PB6) supplementation significantly (p < 0.05) increased the fat content in the internal egg content and cholesterol content in egg yolk expressed as g/pc.

Published: March 2013

Objective To identify microRNAs (miRNAs) that are overexpressed in renal cell carcinoma (RCC) and characterize the functional role of miR-21. Materials and Methods The miRNA expression profiles between RCC tissue and adjacent normal tissue were compared using microarray analysis. The differential expression of miR-21 was validated by real-time polymerase chain reaction (RT-PCR). 786-O RCC cells were transfected with miR-21 mimic, miR-21 inhibitor, or negative controls and cell proliferation, apoptosis and cell cycle were examined by MTT assay and flow cytometry. The expression of programmed cell death 4 (PDCD4) and tropomyosin 1 (TPM1) was detected by RT-PCR and Western blot analysis. Results Compared to adjacent normal tissue, 10 human miRNAs were significantly upregulated and 7 were downregulated in RCC tissue. RT-PCR confirmed that miR-21 was significantly overexpressed in RCC tissue. In vitro expression of miR-21 mimic promoted the growth of 786-O cells, whereas miR-21 inhibitor inhibited cell growth by inducing apoptosis and cell cycle arrest at S phase. Furthermore, miR-21 mimic or inhibitor significantly reduced or increased the expression of PDCD4 and TPM1. Conclusions MiR-21 is overexpressed in RCC tissue and modulates the growth, apoptosis and cell cycle progression of RCC cells and regulates the expression of PDCD4 and TPM1.
