STATIC AND DYNAMIC ANALYSIS OF THE FOOT IN SOCCER PLAYERS SUSTAINING PROXIMAL 5TH METATARSAL STRESS FRACTURE
Stress fracture of the proximal 5th metatarsal (MT) is a well recognized entity among athletes. Identification of specific risk factors for this injury may play an important role injury prevention. Lateral oveloading in rigid cavus foot have been suggested as contributing factors (Williams, 2001). The purpose of our study was to characterize static variables of foot structure and dynamic variables of foot function in soccer players which sustained 5th MT stress fracture
FOOT PRONATION AND STRESS FRACTURES OF THE FEMUR AND TIBIA: A PROSPECTIVE BIOMECHANICAL STUDY
The relation between foot pronation and stress fractures has been suggested. However, evidence based literature is lacking and contradictory. The purpose of this study was to
examine whether dynamic parameters of foot pronation are related to the development of stress fractures of the femur and tibia. 2 weeks prior to beginning of 14 weeks of basic
military training, 473 infantry recruits were inrolled into the study. 2D analysis was performed to measure foot pronation during treadmill walking. The soldiers were examined during the training course at two weeks intervals for stress fractures. The odds ratio was calculated for each dynamic pronation parameter in relation to the stress fractures. 10% of the 405 soldiers who finished the training were diagnosed with stress
fractures of the femur and tibia. Longer pronation time was related to risk reduction for the development of stress fractures and may have a protective effect during an extended
period of training
Understanding Barriers to the Realization of Human Rights Among Older Women With Mental Health Conditions
There is increasing emphasis in research and at the level of international human rights bodies such as the United Nations on the gendered contours of age-based disadvantage and discrimination, and the cumulative effects of gender inequalities over the life-course on outcomes in later life. However, to date, the role of mental health in shaping the age/gender nexus in the realization of human rights has received little attention. In response, this paper aims to 1) elucidate the economic, social and cultural disadvantages and discrimination faced by older women living with mental health conditions; and 2) identify opportunities to protect their human rights. It concludes that older women face inequalities and disadvantages at the intersections of age, gender, and mental health and wellbeing that compromise their capacity to age well, illuminating the urgent need for a UN Convention on the Human Rights of Older Persons that considers the role of mental health in shaping the realization of human rights among older people.

How do older people discuss their own sexuality? A systematic review of qualitative research studies
This study captured older peopleâs attitudes and concerns about sex and sexuality in later life by synthesising qualitative research published on this issue. The systematic review was conducted between November 2015 and June 2016 based on a pre-determined protocol. Key words were used to ensure a precise search strategy. Empirically based, qualitative literature from 18 databases was found. Twenty studies met the inclusion criteria. Thomas and Hardenâs thematic synthesis was used to generate âanalytical themesâ which summarise this body of literature. Three main themes were identified: (a) social legitimacy for sexuality in later life; (b) health, not age, is what truly impacts sexuality, and (c) the hegemony of penetrative sex. The themes illustrate the complex and delicate relation between ageing and sexuality. Older adults facing health issues that affect sexual function adopt broader definitions of sexuality and sexual activit
Isokinetic moment curve abnormalities are associated with articular knee lesions
The aim of this study was to test whether lesions of the medial meniscus (MM) and of the anterior cruciate ligament (ACL) are associated with specific abnormalities of isokinetic moment curves (IMCs). Fifty-four young adults (20 active healthy people, and 34 patients with unilateral knee injuries) were assessed through knee extensor and flexor isokinetic tests at 60\ub0/s. Qualitative IMC analysis was performed using a novel classification system which identified three distinct abnormal shapes. The chi-squared (\u3c72) test was used to determine the inter-individual and intra-individual differences between the groups. Quantitative IMC inter-group comparisons were performed by a one-way analysis of variance (ANOVA). Knees with MM and ACL lesions were consistently associated with IMC shape irregularities (p<0.001) and with abnormal quantitative scores (p<0.001). More specifically, knees with isolated ACL lesions and knees with combined ACL and MM lesions presented similar distribution of knee extensor and flexor IMC irregularities, which was not present in knees with isolated MM lesions. A possible association between specific knee pathologies and IMC irregularities was identified (all p<0.05). In conclusion, different knee pathologies may be associated with different qualitative IMCs, which could be used as an additional presentation tool in clinical settings
Lithium isotopes in speleothems: temperature-controlled variation in silicate weathering during glacial cycles
Terrestrial chemical weathering of silicate minerals is a fundamental component of the global cycle of carbon and other elements. Past changes in temperature, rainfall, ice cover, sea-level and physical erosion are thought to affect weathering but the relative impact of these controls through time remains poorly constrained. This problem could be addressed if the nature of past weathering could be constrained at individual sites. In this study, we investigate the use of speleothems as local recorders of the silicate weathering proxy, Li isotopes. We analysed 7Li and [Li] in speleothems that formed during the past 200 ka in two well-studied Israeli caves (Soreq and Tzavoa), as well as in the overlying soils and rocks. Leaching and mass balance of these soils and rocks show that Li is dominantly sourced from weathering of the overlying aeolian silicate soils. Speleothem 7Li values are ubiquitously higher during glacials (~23â°) than during interglacials (~10â°), implying more congruent silicate weathering during interglacials (where âcongruentâ means a high ratio of primary mineral dissolution to secondary mineral formation). These records provide information on the processes controlling weathering in Israel. Consideration of possible processes causing this change of weathering congruency indicates a primary role for temperature, with higher temperatures causing more congruent weathering (lower 7Lispeleo). The strong relationship observed between speleothem d7Li and climate at these locations suggests that Li isotopes may be a powerful tool with which to understand the local controls on weathering at other sites, and could be used to assess the distribution of weathering changes accompanying climate change, such as that of Pleistocene glacial cycles
Unusual association of alveolar rhabdomyosarcoma with pancreatic metastasis: emerging role of PET-CT in tumor staging
Pancreatic metastases in childhood cancer have been rarely reported in the radiology literature although ample evidence exists in pathology reports for its occurrence in patients with alveolar rhabdomyosarcomas (RMS).
Assess the occurrence of pancreatic metastases in alveolar rhabdomyosarcomas, increase awareness of this association and reassess current staging protocols.
Three major oncology centers reviewed their records and imaging examinations. Patientsâ history and demographics, primary tumor site and histology, presence of tumor recurrence, and presence and location of other metastases were reviewed.
Pancreatic metastases occurred in eight patients with alveolar RMS. Four of these presented at diagnosis and four with disease recurrence. In recurrent disease, the duration between the diagnosis of the primary tumor and pancreatic metastases varied from 8 months to 6 years (meanâ±âSD: 2.38â±â2.49 years). In all patients who received PET scans, pancreatic metastases showed a marked FDG-uptake, but had variable detectability with CT. Pancreatic metastases were not associated with certain primary tumor locations or presence of other metastases, mandating an evaluation of the pancreas in all cases of alveolar rhabdomyosarcomas.
Radiologists should be sensitized and actively evaluate the pancreas in patients with alveolar RMS. Optimizing CT and PET-CT protocols may increase the diagnostic yield
A comparison of two anaerobic test measurement systems using an upper body Wingate test
This study aimed to compare performance measures acquired by two different Wingate Anaerobic Test systems; Cranlea and Monark. Twenty participants undertook 58 Wingate tests against a 4% body mass resistive load on a cycle ergometer adapted for arm cranking. Corrected peak power output (PP; W) was recorded using 1 rev minâ1, 0.5, 1 and 5 s averages and mean power output (MP; W). The Cranlea system recorded the greatest PP (589 ± 267 W) compared with the Monark (546 ± 267 W; P < 0.001). The PP using all other methods was also greater for the Cranlea compared with the Monark system (P < 0.001) with mean differences of 55 ± 18 W for 1 s averages and 22 ± 18 W for MP. Correlations between all PPs were strong (r = 0.99 â 0.97; P < 0.001). In conclusion, although the Cranlea system provides a consistently greater corrected PP it may not be enough to substantially differentiate between systems
