Cartilage repair or restoration in the knee provides short-term success with microfracture, autologous chondrocyte implantation, or osteochondral autograft. There are patient-specific and defect-specific factors that influence clinical outcomes.
These results may be used to help predict the outcome of surgical treatment of FAI in different patient populations and to assess the need for labral refixation.
Objective Impairments associated with attention-deficit/hyperactivity disorder (ADHD) and noncompliance are prevalent in children with autism spectrum disorder (ASD). However, ADHD response to stimulants is well below rates in typically developing children, with frequent side effects. Group studies of treatments for noncompliance are rare in ASD. We examined individual and combined-effectiveness of atomoxetine (ATX) and parent training (PT) for ADHD symptoms and noncompliance. Method In a 3-site, 10-week, double-blind, 2×2 trial of ATX and PT, 128 children (ages 5–14) with ASD and ADHD symptoms were randomized to ATX, ATX+PT, placebo+PT, or placebo. ATX was adjusted to optimal dose (capped at 1.8 mg/kg/day) over 6 weeks and maintained for 4 additional weeks. Nine PT sessions were provided. Primary outcome measures were the parent-rated DSM ADHD symptoms on the Swanson, Nolan and Pelham (SNAP) scale and Home Situations Questionnaire (HSQ). Results On the SNAP, ATX, ATX+PT and placebo+PT were each superior to placebo (effect sizes 0.57–0.98), with p-values of 0.0005, 0.0004 and 0.025, respectively. For noncompliance, ATX and ATX+PT were superior to placebo (effect sizes 0.47–0.64; p values of .03 and .0028, respectively). ATX was associated with decreased appetite but otherwise well-tolerated. Conclusion Both ATX and PT resulted in significant improvement on ADHD symptoms while ATX (both alone and combined with PT) was associated with significant decreases on measures of noncompliance. ATX appears to have a better side effects profile than psychostimulants in the population with ASD.
As we age, there is an increased risk for the development of pulmonary diseases, including infections, but few studies have considered changes in lung surfactant and components of the innate immune system as contributing factors to the increased susceptibility of the elderly to succumb to infections. We and others have demonstrated that human alveolar lining fluid (ALF) components, such as surfactant protein (SP)-A, SP-D, complement protein C3, and alveolar hydrolases, play a significant innate immune role in controlling microbial infections. However, there is a lack of information regarding the effect of increasing age on the level and function of ALF components in the lung. Here we addressed this gap in knowledge by determining the levels of ALF components in the aging lung that are important in controlling infection. Our findings demonstrate that pro-inflammatory cytokines, surfactant proteins and lipids, and complement components are significantly altered in the aged lung in both mice and humans. Further, we show that the aging lung is a relatively oxidized environment. Our study provides new information on how the pulmonary environment in old age can potentially modify mucosal immune responses, thereby impacting pulmonary infections and other pulmonary diseases in the elderly population.
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting toxicity of several commonly used chemotherapy drugs including taxanes, vinca alkaloids, and platinum compounds. Development of CIPN is highly variable, both in self-reported symptoms and functional consequences, and can be severe enough to alter dose intensity. PURPOSE To describe the natural histories of both patient-reported symptoms of chemotherapy-induced peripheral neuropathy (CIPN) and functional impairments in breast cancer patients undergoing taxane-based chemotherapy. METHODS Thirty-three breast cancer patients (32 female/1 male; 47.8 ± 11.2 years; n=17 stage II/n=16 stage III) were enrolled. Patients completed self-reports of symptoms and function (e.g., EORTC QLQ-CIPN20) and objective measures of physical function (i.e., balance and gait testing) in an outpatient oncology clinic at five timepoints: (1) baseline - prior to starting chemotherapy, (2–4) before starting subsequent chemotherapy cycles, and (5) 1–3 months after receiving their last taxane infusion. RESULTS Significant negative changes in both patient-reported outcomes and objective functional measures were observed. Decreased balance was observed after the first chemotherapy cycle (28% increase in medial-lateral excursion of the center of pressure, p=0.016) and progressed with cumulative exposure (43% increase, p<0.001). Patients also demonstrated slower walking speeds (5% decrease, p=0.003) as they progressed through treatment. These functional deficits were mirrored with increased patient-reported symptom severity for all EORTC QLQ-CIPN20 subscales (all p<0.05). CONCLUSION This study longitudinally assessed patient-reported outcomes concurrently with balance and gait testing in patients undergoing taxane therapy. Taxane treatment was associated with the development of clinically-relevant problems in both CIPN symptoms and patient function.
Background Recently lumbopelvic control has been linked to pitching performance, kinematics and loading; however, poor lumbopelvic control has not been prospectively investigated as a risk factor for injury in baseball pitchers. Hypothesis Pitchers with poor lumbopelvic control during spring training are more likely to miss 30 or more days due to injury through an entire baseball season than pitchers with good lumbopelvic control. Study design Cohort study. Methods Three hundred forty-seven professional baseball pitchers were enrolled into the study during the last 2 weeks of spring training and stayed with the same team for the entire season. Lumbopelvic control was quantified by peak anterior-posterior deviation of the pelvis relative to starting position during a single leg raise test (APScore). Days missed due to injury through the entire season were recorded by each team's medical staff. Results Higher APScore was significantly associated with a higher likelihood of missing 30 days or more (Chi-Square, p=0.023). When divided into tertiles based on their APScore, participants in the highest tertile were 3.0 times and 2.2 times more likely to miss at least 30 days throughout the course of a baseball season relative to those in the lowest or middle tertiles, respectively. Higher APScore was also significantly associated with missing more days due to injury within participants who missed at least one day to injury (ANOVA, p=0.018), with the highest tertile missing significantly more days (mean=98.6 d) than the middle tertile (mean=45.8d, p=0.017) or the lowest tertile (mean=43.8, p=0.017). Conclusion This study found that poor lumbopelvic control in professional pitchers was associated with increased risk of missing significant time due to injury.
Purpose We have shown the feasibility of administering inhaled doxorubicin to patients with cancer. This study evaluated inhaled doxorubicin combined with cisplatin and docetaxel in patients with non–small cell lung cancer. The principal objective was to determine safety and, secondarily, efficacy. Experimental Design Patients who had chemo-naïve advanced non–small cell lung cancer were enrolled in the study. Adequate organ and pulmonary function was required: diffusing capacity for carbon monoxide/forced expiratory volume in 1 second/forced vital capacity ≥50%, resting/exercise O2 saturation ≥90%/85%. In phase I, doxorubicin was escalated: dose level 1 (6 mg/m2) and level 2 (7.5 mg/m2). Escalation was permitted if ≤2 of 6 patients experienced pulmonary dose-limiting toxicity (grade 2 Radiation Therapy Oncology Group lung morbidity; resting O2 saturation of <85%; decrease in diffusing capacity for carbon monoxide, forced vital capacity, or forced expiratory volume in 1 second of ≥20% from baseline or ≤30% of predicted; or grade 3 Common Terminology Criteria for Adverse Events version 3.0 pulmonary toxicity). Doses of cisplatin and docetaxel were 75 mg/m2. Treatments and pulmonary function tests were repeated every 21 days, with up to eight cycles for responding patients. Results Twenty-eight patients were treated at level 1 and eight patients at level 2. Doxorubicin was escalated to 7.5 mg/m2, however, after two patients developed pulmonary dose-limiting toxicity; the remainder were treated at 6.0 mg/m2. Twenty-four evaluable patients received at least two courses or had progressive disease following the first course at the phase II dose. Toxicity was associated with i.v. chemotherapy although one patient had delayed pulmonary toxicity responding to corticosteroids and oxygen. Seven (29%) evaluable patients responded (six partial responses and one complete response) and 13 (54%) patients had stable disease for up to eight cycles. Conclusion Although this combination was safe, the primary objective was not met and will not be pursued further.
