More than just a seat at the table: the power of youth voice in ending youth homelessness in the United States

ABSTRACT

Each year, over 600 youth under the age of 25 experience literal homelessness in Austin, Texas. Of these youth, 76% have a history of involvement with foster care or the juvenile justice system—far exceeding the rates of system involvement observed among homeless youth in other large communities in the United States (approximately 54%; Voices of Youth Count, 2017). Recently, Austin was selected by the U.S. Department of Housing & Urban Development as one of ten communities nationwide to participate in the Youth Homelessness Demonstration Program (YHDP), a federal initiative designed to effectively end youth homelessness by 2020. Youth with lived experience are central players in the development and implementation of Austin's response to the youth homelessness crisis. A group of twelve of these youth (the “Austin Youth Collective to End Youth Homelessness,” or AYC) serve as key decision-making partners within the Austin YHDP team. Representatives of the AYC are deeply involved at every level of the community planning process, from the development of youth-centric housing options to system redesign efforts to ensure that youth do not exit the foster care or juvenile justice systems to homelessness. The article provides an overview of the development and contributions of the AYC—including their programmatic recommendations and advocacy work—as well as key recommendations for communities looking to leverage youth voice at the systems level.     

Elastic properties of Thiel‐embalmed human ankle tendon and ligament

Thiel embalming is recommended as an alternative to formalin‐based embalming because it preserves tissue elasticity, color, and flexibility in the long term, with low infection and toxicity risk. The degree to which Thiel embalming preserves elasticity has so far been assessed mainly by subjective scoring, with little quantitative verification. The aim of this study is to quantify the effect of Thiel embalming on the elastic properties of human ankle tendons and ligament. Biomechanical tensile tests were carried out on six Thiel‐embalmed samples each of the peroneus longus, peroneus brevis, and calcaneal tendons, and the calcaneofibular ligament, with strain rates of 0.25%s^?1, 2%s^?1, and 8%s^?1. The stress?strain relationship was calculated from the force‐extension response with cross‐sectional area and gauge length. Young's modulus was determined from the stress?strain curve. The results showed that the tendon and ligament elasticity were lower after Thiel embalming than the literature values for fresh nonembalmed tendons and ligament. The biomechanical tensile test showed that the measured elasticity of Thiel‐embalmed tendons and ligaments increased with the strain rate. The Thiel embalming method is useful for preserving human ankle tendons and ligaments for anatomy and surgery teaching and research, but users need to be aware of its softening effects. The method retains the mechanical strain rate effect on tendons and ligament. Clin. Anat. 28:917–924, 2015. © 2015 Wiley Periodicals, Inc.     

The behaviour change techniques used by Australian physiotherapists to promote non-treatment physical activity to patients with musculoskeletal conditions

Objectives

To determine: (i) the behaviour change techniques used by a sample of Australian physiotherapists to promote non-treatment physical activity; and (ii) whether those behaviour change techniques are different to the techniques used to encourage adherence to rehabilitation exercises.

Inherently decoupled 1H antennas and 31P loops for metabolic imaging of liver metastasis at 7 T

High field ³¹P spectroscopy has thus far been limited to diffuse liver disease. Unlike lower field‐strength scanners, there is no body coil in the bore of the 7 T and despite inadequate penetration depth (<10 cm), surface coils are the current state‐of‐the‐art for acquiring anatomical images to support multinuclear studies. We present a system of proton antennas and phosphorus loops for ³¹P spectroscopy and provide the first ultrahigh‐field phosphorus metabolic imaging of a tumor in the abdomen. Herein we characterize the degree to which antennas are isolated from underlying loops. Next, we evaluate the penetration depth of the two antennas available during multinuclear examinations. Finally, we combine phosphorus spectroscopy (two loops) with parallel transmit imaging (eight antennas) in a patient. The loops and antennas are inherently decoupled (no added circuitry, <0.1% power coupling). The penetration depth of two antennas gives twice that of conventional loops. The liver and full axial slice of the abdomen were imaged with eight transmit/receive antennas using parallel transmit B1‐shimming to overcome image voids. Phosphorus spectroscopy from a liver metastasis resolved individual peaks for phosphocholine and phosphoethenalomine. Proton antennas are inherently decoupled from phosphorus loops. By using two proton antennas it is possible to perform region‐of‐interest image‐based shimming in over 80% of the liver volume, thereby enabling phosphorus spectroscopy of localized disease. Shimming of the full extent of the abdominal cross‐section is feasible using a parallel transmit array of eight antennas. A system architecture capable of supporting eight‐channel parallel transmit and multinuclear spectroscopy is optimal for supporting multiparametric body imaging, including metabolic imaging, for monitoring the response of patients with liver metastases to cancer treatments and for patient risk stratification. In the meantime, the existing infrastructure using two antennas is sufficient for preliminary studies in metabolic imaging of tumors in the liver.     

Hydroxyurea-induced genital ulcers and erosions: Two case reports

Hydroxyurea is a chemotherapeutic agent used for myeloproliferative disorders and sickle cell anemia that is well known to cause painful mucocutaneous ulcers, typically involving the legs or mouth. However, genital ulcerations due to hydroxyurea therapy are a rare, and likely underrecognized, adverse effect with only a few cases reported in the literature to date. Ulcers of the lower legs caused by hydroxyurea are associated with a diagnostic delay, and this is likely exacerbated in cases of genital ulceration due to a lack of awareness. Herein we present two cases of painful genital ulceration in patients on hydroxyurea therapy. In the first Case, an 87 year-old male with polycythemia vera developed an ulcer on the scrotum, which was assessed initially through virtual visits during the COVID-19 pandemic, and was refractory to topical and oral antibiotic treatments. The second case was a 79 year-old male with essential thrombocythemia and a history of persistent leg ulcers who developed erosions of the glans penis. Both patients experienced complete resolution within weeks of discontinuing hydroxyurea therapy. In conclusion, genital ulcers and erosions induced by hydroxyrea may be underrecognized in clinical practice, but if identified, withdrawal of hydroxyurea leads to quick resolution of these lesions and the associated pain.

Platelet—Rich—Plasma Injections in Treating Lateral Epicondylosis: a Review of the Recent Evidence

Lateral epicondylosis is common, with various treatment modalities. Platelet—rich—plasma injections from autologous blood have recently been used in centres worldwide for the treatment of tennis elbow. We review and present the recent published evidence on the effectiveness of PRP injections for lateral epicondylosis. Nine studies met our inclusion criteria including 6 RCT’s for the purpose of analysis. PRP injections have an important and effective role in the treatment of this debilitating pathology, in cases where physiotherapy has been unsuccessful.
