The association between SAT and VO2peak was partly explained by habitual sedentary time. CONCLUSIONS We demonstrated a significant negative association between cardiorespiratory fitness and SAT in a diverse group of high-risk youth. The inclusion of rigorous, laboratory-based measures and youth with severe obesity extends the previous work in pediatric populations.BACKGROUND Data-driven decision making is an accepted best practice in education, but teachers seldom reflect on data to drive their physical activity (PA) integration efforts. The purpose of this study was to explore the impact of a data-sharing intervention with classroom teachers on teacher-directed movement integration and students' PA and sedentary behavior. METHODS Teacher-directed movement behaviors from 8 classroom teachers in 1 primary school were systematically observed during four 1-hour class periods before (pre) and after (post) an intervention in which teachers individually discussed student movement data with a trained interviewer. Teachers' K-2 students (N = 132) wore accelerometers for 10 school days both preintervention and postintervention. RESULTS Multilevel mixed effects regression indicated a nonsignificant increase in teacher-directed movement from preintervention to postintervention (+7.42%, P = .48). Students' classroom time spent in moderate to vigorous PA increased (males +2.41 min, P less then .001; females +0.84 min, P = .04) and sedentary time decreased (males -9.90 min, P less then .001; females -7.98 min, P less then .001) postintervention. Interview data inductively analyzed revealed teachers' perspectives, including their surprise at low student PA during the school day. CONCLUSIONS Findings suggest that sharing data with classroom teachers can improve student PA and decrease sedentary behavior at school.CASE REPORT A 72-year-old woman with a nontraumatic spinal cord injury developed eschar on her lower right back. An underlying abscess was identified, which upon surgical debridement left a large wound extending down to the hip bone. In addition, the hip suffered from chronic osteomyelitis and was exposed at the bottom of the wound. The wound was initially treated for 5 weeks with Manuka honey but deteriorated further. Next, micropore particle technology (MPPT) was used. It cleared the wound of necrotic tissue based on autolytic debridement and removed the soft tissue infection; over a 3-month period, the wound reduced 50% in volume. Treatment approach was changed to polyhexamethylene biguanide (PHMB) and was applied as a gel once every second day to the wound. After 6 days, it was observed to cause tissue degeneration, disruption of the structure of the exposed bone, and the appearance of froth coming through the hip bone. A pain syndrome developed and the use of PHMB was terminated on day 10. After a wash-out period, the use of MPPT was reinitiated. Over the following 8 months, MPPT continued to control the infectious debris coming from the hip bone and promote healing without affecting the bone or causing side effects. CONCLUSIONS It is generally assumed that the cytotoxic properties of antiseptics seen in cell culture experiments do not occur on wounds. The present case shows these cytotoxic properties are expressed on wounds, and they do disrupt tissues and tissue regeneration.INTRODUCTION Diabetes affects 30 million children and adults in the United States, equivalent to 1 out of every 11 people in the country, and results in costs of $327 billion annually. Interventions that can improve healing rates and/or reduce the size of diabetic ulcers may lower the incidence of infection, rate of amputations, and cost of care. This report is on the use of a collagen wound contact layer in conjunction with negative pressure wound therapy (NPWT) to achieve healing in a chronic diabetic foot ulcer (DFU). CASE REPORT A known patient with type 1 diabetes presented with a chronic DFU of 6 months' duration. Previous treatment modalities included offloading regimens and topical therapies (ie, clostridial collagenase, human platelet-derived growth factors, and 6 applications of a human amniotic membrane allograft). A collagen wound contact layer was applied to the debrided wound bed with subsequent debridements performed every other week, weekly NPWT dressing changes, and weekly contact layer changes. A 91% reduction in wound area was seen at day 35, with complete healing at day 63, and no recurrence at 18 months. CONCLUSIONS The combination of a collagen wound contact layer and weekly NPWT had a significantly positive effect on healing in this chronic DFU. The regimen was well-tolerated and simple to administer in this case.INTRODUCTION Diabetic foot ulcers may lead to nontraumatic amputations of the foot, leading to a decrease in patient quality of life. Transmetatarsal amputations (TMAs) represent an effective surgical procedure in cases of severe foot infection, but the tissue reconstruction is complicated and additional procedures should be considered. The present case report evaluates the wound closure of an open TMA in a patient with diabetes treated with a new aerogel composed of chitosan (ChS) and chondroitin sulphate (CS), without needing a skin graft. CASE REPORT A 72-year-old man with diabetes and a history of successive amputations was admitted to a hospital in Valdivia, Chile, due to a severe infection of toes 2 and 4 of the right foot. After the diagnosis of gangrene and osteomyelitis, the patient underwent a TMA of his right forefoot. The surgeon proposed the incorporation of ChS and CS aerogels to accelerate wound healing to avoid another surgical procedure. The TMA surgical wound area closed 50% after day 28 from starting treatment with aerogels. Complete closure was achieved at day 94 of treatment with aerogels, with good epithelial tissue and favorable cosmetic results and without residual limb deformities. The patient experienced minimal physical and psychological impairment from the procedure. Other surgical procedures were not necessary. CONCLUSIONS Due to the results of this patient, use of ChS and CS aerogels could represent an alternative treatment for forefoot TMA wound closure and prevent further surgical procedures, such as skin grafting. Future works should consider a larger number of cases.The COVID-19 pandemic poses a major challenge in delivering care to wound patients. Due to multiple comorbidities, wound patients are at an increased risk for the most extreme complications of COVID-19 and providers must focus on reducing their exposure risk. The Federal, State, and local governments, as well as payers, have urged hospitals and providers to reduce utilization of nonessential health services, but they also have given more flexibility to shift the site of necessary care to lower risk environments. Providers must be prepared for disruption from this pandemic mode of health care for the next 18 months, at minimum. The wound provider must accept the new normal during the pandemic by adapting their care to meet the safety needs of the patient and the public. The Wound Center Without Walls is a strategy to untether wound care from a physical location and aggressively triage and provide care to patients with wounds across the spectrum of the health system utilizing technology and community-centered care.OBJECTIVE This case report explores an effective treatment modality in a medically complicated patient, with considerable wound dehiscence refractory to treatment with negative pressure wound therapy (NPWT). CASE REPORT A 35-year-old woman with a past medical history of hypothyroidism, osteoporosis, and rheumatoid arthritis treated with tumor necrosis factor (TNF) alpha inhibitors and disease-modifying antirheumatic drugs presented to the clinic following right great toe arthrodesis, metatarsal neck osteotomies, extensor tendon lengthening, and capsulotomy of the second, third, fourth, and fifth toes 2 weeks prior, with wound dehiscence of the right great toe and subsequent exposure of surgical hardware, complicated by infection. At the 2-week postop, a urinary bladder matrix was placed on the wound following failed NPWT, which was in place for 10 days. At the 3-month follow-up, the wound was closed and without any drainage. Patient reported a significant reduction in pain (visual analogue scale 3) with adherence to weight-bearing restrictions. CONCLUSIONS Wound healing was accomplished without removal of the exposed deep hardware in a patient with comorbidities and post-surgical wound dehiscence.INTRODUCTION A Morel-Lavallée lesion (MLL) is a rare and aesthetically concerning condition caused by a shearing force between subcutaneous fat and underlying fascia. Subsequent seroma formation occurs after the initial trauma of a crush injury, ligamentous sprain, or abdominal liposuction. Misdiagnosed lesions lead to inadequate treatment and are a source of chronic pain. CASE REPORT The case of a 33-year-old woman who presented with a large, painful subacute MLL of the left thigh after being run over by a truck 3 weeks prior is reported. Physical examination revealed severe hyperesthesia and fluctuance of the left thigh. selleck chemicals llc After confirmation of the fluid collection by X-ray and computed tomography angiogram, the authors performed liposuction of the cavity and seroma wall to evacuate and treat the lesion. Postoperative care consisted of a temporary drain, thigh compression, and oral antibiotics. Immediate reduction in size was appreciated intraoperatively with no reaccumulation of fluid at postoperative visits on week 1 and week 6. The pathology report confirmed seroma etiology, and all cultures of the fluid returned negative. At the end of her postoperative course, the patient reported a reduction in pain and no recurrence of her symptoms. CONCLUSIONS This case of MLL was diagnosed early and successfully treated with liposuction, resulting in an acceptable cosmetic outcome. It is the authors' hope that this case report will lead to earlier diagnosis and proper treatment of MLLs.INTRODUCTION Pyoderma gangrenosum (PG) is a rare, ulcerating neutrophilic dermatosis often associated with inflammatory bowel disease, rheumatoid arthritis, and myeloproliferative disorders. The classic description of PG includes irregularly shaped ulcers with undermined edges with a gun-metal gray or violaceous hue. The etiology remains unclear but appears to be related to genetically predisposed dysregulation of the innate immune system. Diagnosis of PG can be difficult as it can present with symptoms similar to cutaneous infections including erythema, edema, ulceration, fever and leukocytosis. Surgical procedures are generally contraindicated in patients with PG due to the risk of pathergy, excessive cutaneous injury, or ulceration in response to trauma. CASE REPORT The authors report the development of PG with the initiation of chemotherapy in a 46-year-old woman with breast cancer. The patient had a complicated clinical course after multiple surgical debridements due to an initial misdiagnosis of necrotizing fasciitis. The patient's rapid onset of post-procedural ulceration was consistent with the pathergy of PG. The diagnosis of PG was confirmed by skin biopsy, which revealed a diffuse neutrophilic infiltrate, and with the patient's negative cultures and response to steroids. The patient was treated with perioperative prednisone and intravenous immunoglobulin prior to a mastectomy for her breast cancer. The surgery was not complicated by pathergy. CONCLUSIONS This unique case highlights the challenging aspects in the medical and perioperative management of active PG in a patient with breast cancer.
