RESUMEN
OBJECTIVE: To examine the association of lifestyle behaviours (LSB) with physical activity (PA) and frailty; also, to examine if associations differ by sex and age. METHODS: 24,828 individuals [49.6 ± 17.6 years (range: 20-85), 51.6 % female] from the National Health and Nutrition Examination Survey (cycles 2009-2018) were included. Individuals were divided into Active (≥150 min/week of moderate-to-vigorous physical activity (MVPA)) and Inactive (<150 min/week MVPA) based on self-reported PA. Frailty was measured by a 46-item Frailty Index (FI). LSB consisted of stationary time, sleep, diet quality, and alcohol and smoking habits. LSB was summed into a score [0-5]. Linear regression models were used with each LSB in isolation and the summed LSB with frailty. RESULTS: There were 7,495 (30.1 %) Active and 17,333 (69.8 %) Inactive individuals. The FI was lower in the Active participants (Active: 0.10 ± 0.08; Inactive: 0.15 ± 0.12; p < 0.01). A worse LSB score was associated with an increased FI in all behaviours but females who binge drink and smoke (p-all>0.14). For inactive individuals, all LSBs were associated with an increased FI except those who binge drink and male smokers (p = 0.08). There was a significant association between increased summed LSB and an increased FI (ß range: Active, 0.024-0.037; Inactive, 0.028, 0.046. p-all<0.01); the Active group had a lower FI at every age group than the Inactive group (p < 0.001). CONCLUSION: PA was associated with a lower FI even among those with a poor LSB score. This association is dependent on age, with older individuals reporting a stronger association.

Introduction and Objective: The penile metastasis is a rare clinical entity. The objective is to present the first documented case report of penile metastasis from right colon. Clinical Case: A case of a 78-year-old man who was diagnosed with penile metastasis from right colon. The patient came to our consultation complaining of colic pain in the kidney and swelling of the penile which finally result in a malignant priapism. The diagnosis was histopathologic and was treated with chemotherapy and died few months later. Conclusion: Metastatic lesions in the penile are extremely rare; only 300 cases have been reported in the literature. It is a sign of bad prognosis. The mechanism of metastatic spread to the penis is not well established. Even there are several treatment options, is usually paliative (AU)

RESUMEN
OBJECTIVE(S): Identifying provider variation in surgical costs could control rising healthcare expenditure and deliver cost-effective care. While these efforts have mostly focused on complex and expensive operations, provider-level variation in costs of thyroidectomy has not been well examined. METHODS: We retrospectively evaluated 921 consecutive total thyroidectomies performed by 14 surgeons at our institution between September 2011 and July 2016. Data were extracted from the Change Healthcare Performance Analytics Program. RESULTS: Mean patient age was 47.4 ± 0.5 y, 81% were females, 64.7% were Caucasians, and 18.8% were outpatients. The number of thyroidectomies performed by the 14 surgeons ranged from 4 to 597 (mean = 66). The mean costs per provider varied widely from $4,293 to $15,529 (P < 0.001). The mean length of stay was 1d ± .03 with wide variation among providers (0-6 d). Providers whose hospital cost exceeded the institutional mean demonstrated significantly higher anesthesia fees and lab costs (P < 0.001). CONCLUSIONS: We found substantial variation in hospital cost among providers for thyroidectomy despite practicing in the same academic institution, with some surgeons spending 3x more for the same operation. Implementing institutional standards of practice could reduce variation and the costs of surgical care.

RESEARCH QUESTION: There is some controversy regarding the impact of ovarian stimulation on immune cells in women undergoing IVF. The study's aim was to determine whether ovarian stimulation affected immune uterine cells in healthy women undergoing IVF. DESIGN: This prospective cohort study included 28 patients undergoing IVF and 47 healthy oocyte donors. Endometrial biopsies were taken in a natural cycle and after ovarian stimulation. All participants had a normal karyotype, pelvic ultrasound and cervical cytology results and thyroid-stimulating hormone concentration, as well as normal glucose and insulin concentrations and inherited and acquired thrombophilia test results. Screening tests including human papillomavirus were normal. Immune cells were analysed using three techniques: fluorescence-activated cell sorting, immunohistochemistry and gene expression. A human leukocyte antigen (HLA)-C tetramer was used as an 'artificial embryo'. The expression of genes including those for tumour necrosis factor (TNF)-α and interleukin-10 (IL-10) was analysed. RESULTS: A comparison was made of the percentage and gene expression of CD56brightCD16- uterine natural killer (uNK), CD56dimCD16+ natural killer cells, CD56-CD16+ natural killer cells and TregCD25+CD4+FoxP3+ cells, uNK binding to the HLA-C tetramer, and TNF-α and IL-10 expression. No between- or within-group differences were observed in natural versus ovarian stimulation cycles. CONCLUSIONS: Ovarian stimulation does not affect the uterine immune cell population or HLA-C binding in healthy women undergoing ovarian stimulation. Further studies are underway to find out if different responses might be seen in women with previous autoimmune disorders.

BACKGROUND: The majority of lower limb amputations (LLA) in Canada are dysvascular due to complications of diabetes and/or vascular disease. Traditionally dysvascular amputations have occurred in the elderly. With younger onset of adult diabetes, amputations are now occurring in non-geriatric populations. An understanding of younger patients with dysvascular LLA is needed to determine their risk factors, and unique health and psychosocial challenges. OBJECTIVES: To obtain a depiction of the key demographic and impairment characteristics of adults 65 years and younger with dysvascular LLA undergoing inpatient rehabilitation. METHODOLOGY: A retrospective chart review was completed on inpatient adult amputation rehabilitation patients over a five year period. Data extracted included socio-demographics, Functional Independence Measure (FIM) scores, comorbidities, and discharge outcomes. FINDINGS: One hundred and forty-three patients who were 65 years and younger were included, which represented almost a quarter of all admissions. Most patients were male (79%) with an average age of 55 years old (SD=8). The majority (72%) were unemployed. The mean number of co-morbidities was 5.2 (SD=8.2). Individuals discharged home (n=122) had higher (p<0.05) FIM scores than those readmitted to acute care or discharged to long-term care (n=20). CONCLUSIONS: Similar to the literature on older dysvascular LLA patients, our study found high rates of disability and co-morbidities in younger patients with dysvascular LLA, which might impact their ability to work. Given these challenges, better amputation prevention strategies and targeted rehabilitation programming for this population are needed.
RESUMEN
CONTEXT: Kisspeptin role in metabolism has been implicated recently. However, the nature of the signals that may connect body fat/muscle tissues with the central nervous system governing energy homeostasis remains to be elucidated. OBJECTIVE: The present study was designed to investigate the effects of peripheral kisspeptin-10 administration on irisin release in human males. SUBJECTS AND METHODS: Kisspeptin-10 was administered to normal weight (n=8) and obese (n=8) men. Sequential blood sampling was performed for 30 minutes pre and 210 minutes post kisspeptin injection at 30 minutes interval. ELISA kit was used to detect plasma irisin levels. RESULTS: There is a significant (P<0.0001) effect of Kisspeptin-10 administration on irisin release in both normal weight and obese participants. Mean irisin levels (96.24 ± 1.351 ng/mL) at 210 minutes were significantly (P<0.0001) enhanced as compared to pre-kisspeptin (59.18 ± 4.815 ng/mL) in normal weight subjects. In obese subjects mean irisin levels (75.76 ± 4.06 ng/mL) were significantly (P<0.0001) elevated at 180 minutes post-kisspeptin when compared with pre-kisspeptin irisin levels (41.28 ± 2.89 ng/mL). CONCLUSION: Our findings suggest that kisspeptin may have a novel therapeutic potential to induce irisin release in humans which may have anti-obesity effects.
RESUMEN
BACKGROUND: The majority of older adults do not reach the physical activity guidelines. One possible explanation for this may be that older adults overestimate their physical activity levels, because they are unable to identify exercise intensity. METHODS: Forty-four older adults were recruited and randomly assigned into two walking groups lasting 6 weeks. The intervention group was asked to walk a minimum of 150 min per week at moderate intensity using walking cadence indicated with a pedometer. The control group did not get any feedback on walking intensity. RESULTS: The ability to identify moderate intensity while walking did not significantly improve in neither groups (p = 0.530). However, participants in the intervention group increased significantly the time spent at moderate intensity, in 10 min bouts (p < 0.01). DISCUSSION: A pedometer providing walking cadence to reach moderate intensity is a good tool for increasing time walked at the recommended intensity, but not because participants know more what is considered moderate intensity.

Background. Most adults choose walking as a leisure activity. However, many do not reach the international physical activity guidelines for adults, which recommend moderate intensity aerobic activity for at least 150 minutes/week in bouts of 10 minutes. Purpose. This systematic review provides an update on the walking cadence required to reach moderate intensity in adults and older adults, identifies variables associated with reaching moderate intensity, and evaluates how walking cadence intensity should be measured, but the main purpose is to report the interventions that have been attempted to prescribe walking cadence to increase time spent at moderate intensity or other outcomes for adults and older adults. Methods. SportDISCUS, Scopus, and PubMed databases were searched. We identified 3,917 articles and 31 were retained for this systematic review. Only articles written in English were included. Results. In general, 100 steps/minute is prescribed for adults to achieve moderate intensity, but older adults may require a higher cadence. Currently, few studies have explored using walking cadence prescription as an intervention to increase physical activity levels. Conclusion. Prescribing walking cadence as a way to increase physical activity levels has potential as a practical and useful strategy, but more evidence is required to assess its ability to increase physical activity levels at moderate intensity.
