Weightbearing and Activity Restriction Treatments and Quality of Life in Patients with Perthes Disease

BackgroundWeightbearing and activity restrictions are commonly prescribed during the active stages of Perthes disease. These restrictions, ranging from cast or brace treatment with nonweightbearing to full weightbearing with activity restrictions, may have a substantial influence on the physical, mental, and social health of a child. However, their impact on the patient’s quality of life is not well-described.Questions/purposesAfter controlling for confounding variables, we asked (1) are restrictions on weightbearing and activity associated with physical health measures (as expressed by the Patient-Reported Outcome Measurement Information System [PROMIS] mobility, PROMIS pain interference, and PROMIS fatigue) of children in the active stages of Perthes disease? (2) Are these restrictions associated with poorer scores for mental health measures (PROMIS depressive symptoms and PROMIS anxiety)? (3) Are these restrictions associated with poorer scores for social health measures (PROMIS peer relationships)?MethodsBetween 2013 and 2020, 211 patients with Perthes disease at a single institution were assigned six PROMIS measures to assess physical, mental, and social health. Patients who met the following eligibility criteria were analyzed: age 8 to 14 years old, completion of six PROMIS measures, English-speaking, and active stage of Perthes disease (Waldenstrom Stage I, II, or III). Weightbearing and activity restrictions were clinically recommended to patients in the initial through early reossification stages of Perthes disease when patients had increasing pain, loss of hip motion, loss of hip containment, progression of femoral head deformity, increased hip synovitis, and femoral head involvement on MRI or as a postoperative regimen. Patients were categorized into four intervention groups based on weightbearing and activity regimen. We excluded 111 patients who did not meet the inclusion criteria. The following six pediatric self-report PROMIS measures were assessed: mobility, pain interference, fatigue, depressive symptoms, anxiety, and peer relationships. Of the 100 patients, 36 were categorized into the no-restriction regimen, 27 into the mild-restriction regimen, 25 into the moderate-restriction regimen, and 12 into the severe-restriction regimen at the time of PROMIS administration. The median (range) age at diagnosis was 8 years old (range 2 to 13 years). There were 85 boys and 15 girls. Eleven patients had hips in Waldenstrom Stage I, 10 were in Stage II, and 79 were in Stage III. Forty-four patients had hips classified as lateral pillar B and 47 patients as lateral pillar C. Nine patients had not reached the mid-fragmentation stage for appropriate lateral pillar classification by the time they took the PROMIS survey. ANOVA was used to compare differences between the mean PROMIS T-scores of these weightbearing/activity regimens. Results were assessed with a significance of p < 0.05 and adjusted for Waldenstrom stage, gender, age at diagnosis, and history of major surgery using multivariate regression analysis.ResultsAfter controlling for confounding variables, the mild- (β regression coefficient -15 [95% CI -19 to -10]; p < 0.001), moderate- (β -19 [95% CI -24 to -14]; p < 0.001), and severe- (β -25 [95% CI -30 to -19]; p < 0.001) restriction groups were associated with worse mobility T-scores compared with the no-restriction group, but no association was detected for the pain interference or fatigue measures. Weightbearing and activity restrictions were not associated with mental health measures (depressive symptoms and anxiety). Weightbearing and activity restrictions were not associated with social health measures (peer relationships). Earlier Waldenstrom stage was associated with worse pain interference (β 10 [95% CI 2 to 17]; p = 0.01) and peer relationships scores (β -8 [95% CI -15 to -1]; p = 0.03); female gender was linked with worse depressive symptoms (β 7 [95% CI 2 to 12]; p = 0.005) and peer relationships scores (β -6 [95% CI -12 to 0]; p = 0.04); and earlier age at diagnosis was associated with worse peer relationships scores (β 1 [95% CI 0 to 2]; p = 0.03). History of major surgery had no connection to any of the six PROMIS measures.ConclusionWe found that weightbearing and activity restriction treatments are associated with poorer patient-reported mobility in the active stages of Perthes disease after controlling for Waldenstrom stage, gender, age at diagnosis, and history of surgery. Weightbearing/activity restrictions, however, are not associated with pain interference, fatigue, depressive symptoms, anxiety, and peer relationships. Understanding how these treatments are associated with quality of life in patients with Perthes disease can aid in decision-making for providers, help set expectations for patients and their parents, and provide opportunities for better education and preparation. Because of the chronic nature of Perthes disease, future studies may focus on longitudinal trends in patient-reported outcomes to better understand the overall impact of this disease and its treatment.Level of EvidenceLevel III, therapeutic study.     

The Role of Telehealth in Sideline Management of Sports-Related Injuries

The COVID-19 pandemic has affected the ability of the sports medicine physician to be present to participate in in-person sideline evaluation of the injured athlete. The purpose of this review is to assess existing literature regarding the utilization of telehealth for sideline evaluation and management of the injured athlete, as well as to identify further areas of research. With the rapid incorporation of telehealth visits, the utilization and capabilities of telemedicine continue to expand. A number of evidence-based resources are available to support medical providers to develop and utilize video evaluation for the sideline evaluation of sports-related injuries. Future research, including the development of validated, modified examination techniques and technologies, will allow for improved interactive physical examinations, which may be better utilized for sideline evaluation.     

Differences in patient perceptions of integrated care among black,hispanic, and white Medicare beneficiaries

ObjectiveThis study sought to identify potential disparities among racial/ethnic groups in patient perceptions of integrated care (PPIC) and to explore how methodological differences may influence measured disparities.Data SourceData from Medicare beneficiaries who completed the 2015 Medicare Current Beneficiary Survey (MCBS) and were enrolled in Part A benefits for an entire year.Study DesignWe used 4‐point measures of eight dimensions of PPIC and assessed differences in dimensions among racial/ethnic groups. To estimate differences, we applied a “rank and replace” method using multiple regression models in three steps, balancing differences in health status among racial groups and adjusting for differences in socioeconomic status. We reran all analyses with additional SES controls and using standard multiple variable regression.Data Collection/Extraction MethodsNot applicable.Principal FindingsWe found several significant differences in perceived integrated care between Black versus White (three of eight measures) and Hispanic versus White (one of eight) Medicare beneficiaries. On average, Black beneficiaries perceived more integrated support for self‐care than did White beneficiaries (mean difference = 0.14, SE = 0.06, P =.02). Black beneficiaries perceived more integrated specialists’ knowledge of past medical history than did White beneficiaries (mean difference = 0.12, SE = 0.06, P =.01). Black and Hispanic beneficiaries also each reported, on average, 0.18 more integrated medication and home health management than did White beneficiaries (P <.01 and P <.01). These findings were robust to sensitivity analyses and model specifications.ConclusionsThere exist some aspects of care for which Black and Hispanic beneficiaries may perceive greater integrated care than non‐Hispanic White beneficiaries. Further studies should test theories explaining why racial/ethnic groups perceive differences in integrated care.     

Hospice for aged persons without cancer: the experience of the Hampshire County (MA) hospice

Hospice is an option for patients with terminal illness of all types. The advent of the Medicare hospice benefit has led to a rise in numbers of hospice programs as well as hospice expenditure. Terminal care provided through hospice has a demonstrable cost advantage over conventional terminal care. This difference may dissipate as Medicare hospice expenditure continues to rise. An individual hospice program can define its mission within broad guidelines. A program electing to serve all terminally ill patients regardless of diagnosis can occasionally expect to be cast in the role of long term care-provider when six-month survival is exceeded. Precision in prediction of six-month survival would benefit patients and remove one major obstacle to participation by many primary care physicians. Prognostic techniques are being developed that, thus far, have proven no better than physician judgement in assigning risk or predicting survival. Hospice may provide a setting for clinical research of prognostication. The interdisciplinary team can facilitate hospice care and provide support to individual team members. Care of terminally ill non-cancer patients may require added human resources and alteration of team structure to cope with increased service needs and lengths of stay which may be likely to exceed those of cancer patients.     

Prevention of ovarian cancer: intraepithelial neoplasia.

To reduce the incidence and mortality associated with invasive cancers, the Intraepithelial Neoplasia (IEN) Task Force recommends that carcinogenesis be viewed as a disease that requires treatment. This publication outlines the current knowledge of IEN of the ovary and reviews chemoprevention possibilities for ovarian cancer. Ovarian cancer has the highest mortality of all of the gynecological cancers and is the fourth leading cause of death from cancer in women. The IEN Task Force has defined precancer as a noninvasive lesion that has genetic abnormalities, loss of cellular control functions, and some phenotypic characteristics of invasive cancer with a substantial likelihood of developing invasive cancer. The IEN Task Force recommends targeting moderate to severe dysplasia for new IEN treatment agents in clinical trials. Ovarian cancer does not have a clear preinvasive lesion yet merits considerable study for new prevention strategies because of the high mortality associated with ovarian cancer. There is a great unmet clinical need for treatments that can prevent ovarian cancer by providing nonsurgical options that treat the entire epithelial layer. New prevention strategies hold significant promise to reduce the mortality from ovarian cancer.     

Reorganizing the system of care surrounding laparoscopic surgery: a cost-effectiveness analysis using discrete-event simulation.

PURPOSE: To determine the cost-effectiveness of a proposed reorganization of surgical and anesthesia care to balance patient volume and safety. METHODS: Discrete-event simulation methods were used to compare current surgical practice with a new modular system in which patient care is handed off between 2 anesthesiologists. A health care system's perspective, using hospital and professional costs, was chosen for the cost-effectiveness analysis. Outcomes were patient throughput, flow time, wait time, and resource use. Sensitivity analyses were performed on staffing levels, mortality rates, process times, and scheduled patient volume. RESULTS: The new strategy was more effective (average 4.41 patients/d [median = 5] v. 4.29 [median = 4]) and had similar costs (average cost/ patient/d = 5327 dollars v. 5289 dollars) to the current strategy with an incremental cost-effectiveness of 318 dollars/additional patient treated/d. Surgical mortality rate must be >4% or hand-off delay >15 min before the new strategy is no longer more effective. CONCLUSION: The proposed system is more cost-effective relative to current practice over a wide range of mortality rates, hand-off times, and scheduled patient volumes.     

Nasal carriage of methicillin-resistant Staphylococcus aureus in an American Indian population.

BACKGROUND AND OBJECTIVE: Although reports of methicillin-resistant Staphylococcus aureus (MRSA) infections without healthcare exposure are increasing, population-based data regarding nasal colonization are lacking. We assessed the prevalence of and risk factors for community-associated MRSA nasal carriage in patients of a rural outpatient clinic. DESIGN: A cross-sectional population survey was conducted through random sample and stratification by community of residence. Recent healthcare exposure (ie, hospitalization, dialysis, or healthcare occupation) and other risk factors for MRSA carriage were assessed. Cultures of the nares were performed. Community-associated MRSA was defined as MRSA carriage without healthcare exposure. SETTING: A predominantly American Indian community in Washington. PATIENTS: Those receiving healthcare from an Indian Health Service clinic. RESULTS: Of 1,311 individuals identified for study, 475 (36%) participated. Unsatisfactory culture specimens resulted in exclusion of 6 participants. In all, 128 (27.3%) of 469 participants had S. aureus. Nine (1.9%) of 469 had MRSA carriage; of these, 5 had community-associated MRSA (5 of 469; overall community-associated MRSA carriage rate, 1.1%). MRSA carriage was associated with antimicrobial use in the previous year (risk ratio [RR], 7.2; P = .04) and residence in a household of more than 7 individuals (RR, 4.5; P = .03). Pulsed-field gel electrophoresis indicated that 5 (55%) of 9 MRSA carriage isolates were closely related, including 3 (60%) of 5 that were community associated. CONCLUSIONS: Prevalence of community-associated MRSA colonization was approximately 1% in this rural, American Indian population. Community-associated MRSA colonization was associated with recent antimicrobial use and larger household.     

Low-dose outpatient chemobiotherapy with temozolomide, granulocyte-macrophage colony stimulating factor, interferon-alpha2b, and recombinant interleukin-2 for the treatment of metastatic melanoma.

PURPOSE: The objective of this study was to further investigate the efficacy and safety of low-dose outpatient chemobiotherapy in patients with unresectable metastatic melanoma. PATIENTS AND METHODS: Thirty-one patients with histologically confirmed unresectable measurable metastatic melanoma were enrolled onto an open-label, multicenter phase II study. The treatment regimen consisted of oral temozolomide followed by subcutaneous biotherapy with granulocyte macrophage colony-stimulating factor, interferon-alfa, and recombinant interleukin-2 (rIL-2). RESULTS: Twenty-eight patients (90%) had M1c disease, and 58% had three or more sites of metastasis. Four patients (13%), all with M1c disease, had a complete response, and four patients had a partial response. The median progression-free survival was 4.9 months and the median overall survival was 13.1 months. Two patients (6%) developed CNS metastasis as the first site of disease progression, and 7 (23%) of 30 experienced CNS progression after receiving chemobiotherapy. A total of 112 cycles of therapy were administered. Toxicity occurred in 78% of the cycles and was grade 1 or 2 in the majority of cases and easily managed. Grade 4 toxicity occurred in 3% of the cycles. CONCLUSION: This low-dose chemobiotherapy combination produces clinical responses in patients with metastatic melanoma, even in those with M1c disease, is well tolerated, and allows home dosing. It offers a reasonable alternative to high-dose regimens, such as high-dose biochemotherapy or rIL-2 requiring prolonged periods of hospitalization, or single agent outpatient regimens, such as dacarbazine, which is usually not effective in patients with M1c disease. Furthermore, it may protect against the development of brain metastases.
