RESUMO

CONTEXT: Hispanic or Latino men who have sex with men (HLMSM) are disproportionately affected by the HIV/AIDS epidemic in New York State (NYS) and nationally. In 2019, HLMSM comprised 13% of all new diagnoses and 21% of new diagnoses among men who have sex with men (MSM) in NYS excluding New York City. HIV home testing programs are effective methods for increasing HIV testing. OBJECTIVE: This pilot sought to determine whether the NYS HIV Home Test Giveaway (HHTG) can effectively reach priority populations, specifically HLMSM/transgender/gender nonconforming persons who have sex with men, to increase uptake of HIV home testing services and identify new HIV infections. DESIGN/SETTING: We recruited participants using media campaigns linked to a brief self-administered eligibility survey. Eligible participants provided their e-mail address to receive a code for a free HIV home test and were sent a self-administered follow-up survey 4 to 11 weeks after eligibility survey completion. PARTICIPANTS: The 2018 and 2019 NYS HHTG reached 1214 and 1340 participants, respectively. A total of 606 participants in 2018 and 736 participants in 2019 were eligible to receive the HHTG home test kit. MAIN OUTCOME MEASURES: HHTG utilization and test results. RESULTS: Hispanic or Latino persons participated at higher rates (34.8% and 25.4% in 2018 and 2019, respectively) than the percentage of Hispanic men in prioritized zip codes (15.7% and 15.6% in 2018 and 2019, respectively). The majority of participants who received HHTG test kits used them to test themselves (87.5% in 2018 and 90.6% in 2019). Across both rounds, 4 participants reported new HIV-positive results, for a seropositivity rate of approximately 1%. CONCLUSION: Geospatial prioritization was successful in reaching Hispanic or Latino priority populations for HIV testing. HIV self-testing programs such as the HHTG are beneficial methods to reach priority populations for state and national Ending the HIV Epidemic initiatives.

RESUMO

CONTEXT: Gay, bisexual, and men who have sex with men (MSM) are disproportionately affected by the HIV/AIDS epidemic more than any other group. In New York State (NYS) outside of New York City (NYC), MSM accounted for 57% of new HIV/AIDS diagnoses in 2017. HIV/AIDS home testing initiatives have been effective at getting priority populations tested for HIV. OBJECTIVES: The NYS Department of Health (NYSDOH) administered the HIV Home Test Giveaway (HHTG) program through social media and mobile applications popular among the priority populations to (1) promote HIV screening among gay and bisexual men, MSM, transgender (TG), and gender queer/gender nonconforming (GNC) individuals who have sex with men, and (2) identify individuals with undiagnosed HIV infection. DESIGN/SETTING: The NYSDOH recruited participants from NYS (excluding NYC) through social media campaigns between November 2016 and January 2018. Interested individuals were directed to an online eligibility survey. Eligible participants received a coupon via e-mail for a free HIV self-test (HIVST) kit through the manufacturer's Web site. Eligible participants received a $20 to $25 Amazon online gift card if they completed a voluntary online follow-up survey regarding their test results, experiences with the HHTG, and HIV/AIDS risk behaviors. Participants were also able to request assistance from the NYSDOH with further testing and various prevention and supportive services. PARTICIPANTS: In total, 6190 individuals participated and 3197 (52%) were eligible and received a coupon. Of the eligible, 2022 (63%) redeemed coupons for HIVST. RESULTS: Among eligible participants, 976 (31%) reported having never been tested for HIV. On the follow-up survey, 922 (29%) participants reported having used the HIVST kit for themselves; 203 (22%) were first-time testers; and 7 (0.8%) tested HIV reactive. Of the follow-up survey participants, 761 (59%) requested assistance with various services. CONCLUSIONS: Media campaigns were effective in promoting HIV testing among priority populations and reaching individuals who have never been tested for HIV.

RESUMO

PURPOSE: Guselkumab, an interleukin (IL)-23 inhibitor, effectively treats moderate-to-severe plaque psoriasis. MATERIALS AND METHODS: ECLIPSE, was a Phase 3, multicenter, 56-week, double-blinded, active-comparator study of guselkumab vs. secukinumab (IL-17A inhibitor) in patients with moderate-to-severe psoriasis. Patients were treated with guselkumab 100 mg (n = 534) or secukinumab 300 mg (n = 514) through week 44. Efficacy (at least a 90% and 100% improvement from baseline in Psoriasis Area and Severity Index [PASI 90 and PASI 100], Investigator's Global Assessment [IGA] 0/1, and IGA 0) was analyzed across subpopulations defined by baseline: age (<45, 45 to <65, and ≥65 years old), body weight, body mass index (BMI), psoriasis disease severity (body surface area, disease duration, PASI, and IGA), psoriasis by body regions (head, trunk, upper and lower extremities), and prior psoriasis medication history at week 48. RESULTS: Overall, 1048 patients were randomized. At week 48, numerically greater proportions of patients achieved PASI 90, PASI 100, IGA 0/1, and IGA 0 with guselkumab vs. secukinumab regardless of baseline age, body weight, BMI, disease severity, body region, and prior medication. The largest differences were in patients ≥65 years old and patients weighing >100 kg. CONCLUSIONS: Guselkumab treatment provided greater efficacy vs. secukinumab at week 48 in most subpopulations of patients with psoriasis.

RESUMO

BACKGROUND: Antibodies targeting interleukin (IL)-23 and IL-17A effectively treat moderate-to-severe psoriasis. ECLIPSE is the first comparator study of an IL-23p19 inhibitor, guselkumab, versus an IL-17A inhibitor, secukinumab. The primary objective of this study was to show superiority of clinical response at week 48 for guselkumab versus secukinumab. METHODS: In this phase 3, multicentre, double-blind, randomised, comparator-controlled trial at 142 outpatient clinical sites in nine countries (Australia, Canada, Czech Republic, France, Germany, Hungary, Poland, Spain, and the USA), eligible patients were aged 18 years or older, had moderate-to-severe plaque-type psoriasis, and were candidates for phototherapy or systemic therapy. Eligible patients were randomly assigned with permuted block randomisation using an interactive web response system to receive either guselkumab (100 mg at weeks 0 and 4 then every 8 weeks) or secukinumab (300 mg at weeks 0, 1, 2, 3, and 4, and then every 4 weeks). The primary endpoint, the proportion of patients in the intention-to-treat population who achieved 90% reduction or more from baseline of Psoriasis Area and Severity Index (PASI 90 response) at week 48, and major secondary endpoints (the proportions of patients in the guselkumab group and in the secukinumab group who achieved a PASI 75 response at both weeks 12 and 48, a PASI 90 response at week 12, a PASI 75 response at week 12, a PASI 100 response at week 48, an Investigator's Global Assessment [IGA] score of 0 [cleared] at week 48, and an IGA score of 0 or 1 [minimal] at week 48) were to be tested in a fixed sequence to control type I error rate. Safety was evaluated in patients who received one or more doses of study drug from week 0 to 56. The study is registered with ClinicalTrials.gov, NCT03090100. FINDINGS: This study was done between April 27, 2017, and Sept 20, 2018. 1048 eligible patients were enrolled and, of these, 534 were assigned to receive guselkumab and 514 to receive secukinumab. The proportion of patients with a PASI 90 response at week 48 was greater in the guselkumab group (451 [84%]) than in the secukinumab group (360 [70%]; p<0·0001). Although non-inferiority (margin of 10 percentage points) was established for the first major secondary endpoint (452 [85%] of patients in the guselkumab group vs 412 [80%] of patients in the secukinumab group achieving a PASI 75 response at both weeks 12 and 48), superiority was not established (p=0·0616). Consequently, formal statistical testing was not done for subsequent major secondary endpoints. Proportions of patients with adverse events, infections, and serious adverse events were similar between the two treatments and, in general, safety findings were consistent with registrational trial observations. INTERPRETATION: Guselkumab showed superior long-term efficacy based on PASI 90 at week 48 when compared with secukinumab for treating moderate-to-severe psoriasis. This finding could assist health-care providers in their decision making process when selecting a biologic for treating moderate-to-severe psoriasis. FUNDING: This study was funded by Janssen Research & Development.

RESUMO

BACKGROUND: Human rhinoviruses (HRVs) commonly precipitate asthma exacerbations. Toll-like receptor 3, an innate pattern recognition receptor, is triggered by HRV, driving inflammation that can worsen asthma. OBJECTIVE: We sought to evaluate an inhibitory mAb to Toll-like receptor 3, CNTO3157, on experimental HRV-16 inoculation in healthy subjects and asthmatic patients. METHODS: In this double-blind, multicenter, randomized, parallel-group study in North America and Europe, healthy subjects and patients with mild-to-moderate stable asthma received single or multiple doses of CNTO3157 or placebo, respectively, and were then inoculated with HRV-16 within 72 hours. All subjects were monitored for respiratory symptoms, lung function, and nasal viral load. The primary end point was maximal decrease in FEV1 during 10 days after inoculation. RESULTS: In asthmatic patients (n = 63) CNTO3157 provided no protection against FEV1 decrease (least squares mean: CNTO3157 [n = 30] = -7.08% [SE, 8.15%]; placebo [n = 25] = -5.98% [SE, 8.56%]) or symptoms after inoculation. In healthy subjects (n = 12) CNTO3157 versus placebo significantly attenuated upper (P = .03) and lower (P = .02) airway symptom scores, with area-under-the-curve increases of 9.1 (15.1) versus 34.9 (17.6) and 13.0 (18.4) versus 50.4 (25.9) for the CNTO3157 (n = 8) and placebo (n = 4) groups, respectively, after inoculation. All of the severe and 4 of the nonserious asthma exacerbations occurred while receiving CNTO3157. CONCLUSION: In summary, CNTO3157 was ineffective in attenuating the effect of HRV-16 challenge on lung function, asthma control, and symptoms in asthmatic patients but suppressed cold symptoms in healthy subjects. Other approaches, including blockade of multiple pathways or antiviral agents, need to be sought for this high unmet medical need.

RESUMO

BACKGROUND: Limited evidence exists demonstrating an effective treatment for chronic cutaneous sarcoidosis. OBJECTIVE: To determine infliximab's effectiveness in sarcoidosis. METHODS: We conducted a subset analysis from a randomized, double-blind, placebo-controlled trial for chronic pulmonary sarcoidosis to determine infliximab's effectiveness. Patients with chronic cutaneous sarcoidosis received infliximab (3 or 5 mg/kg) or placebo over 24 weeks. Of 138 patients, the subset analysis evaluated 17 patients with chronic facial and another 9 patients with nonfacial skin involvement. The SASI evaluated lesions for degree of erythema, desquamation, induration, and percentage of area involved. Facial and nonfacial lesions were scored in a blinded manner. RESULTS: Among 5 placebo-treated and 12 infliximab-treated patients, an improvement was observed with infliximab versus placebo in change from baseline to weeks 12 and 24 in desquamation (P<0.005) and induration (P<0.01) at week 24. Erythema, percentage of area involved and the evaluation of paired photographs did not reveal significant differences. LIMITATIONS: Sample size; more extensive disease in placebo patients; chronic therapy upon enrollment; lung as primary organ of sarcoidosis involvement; limited investigator experience with SASI. CONCLUSIONS: Infliximab appears to be a beneficial treatment for chronic cutaneous sarcoidosis. The SASI scoring system demonstrated significant improvement versus placebo in lesion desquamation and induration.

RESUMO

The objective of this study was to determine the safety and efficacy of carlumab in the treatment of idiopathic pulmonary fibrosis (IPF).A phase 2, randomised, double-blind placebo-controlled dose-ranging study was conducted in patients with IPF (n=126). Patients were randomised to carlumab (1 mg·kg(-1), 5 mg·kg(-1), or 15 mg·kg(-1)) or placebo every 4 weeks. The primary endpoint was the rate of percentage change in forced vital capacity (FVC). Secondary endpoints were time to disease progression, absolute change in FVC, relative change in diffusing capacity of the lung for carbon monoxide (DLCO), and St George's Respiratory Questionnaire (SGRQ) total score.Due to a pre-planned, unfavourable interim benefit-risk analysis, dosing was suspended. The rate of percentage change in FVC showed no treatment effect (placebo -0.582%, 1 mg·kg(-1) -0.533%, 5 mg·kg(-1) -0.799% and 15 mg·kg(-1) -0.470%; p=0.261). All active treatment groups showed a greater decline in FVC (1 mg·kg(-1) -290 mL, 5 mg·kg(-1) -370 mL and 15 mg·kg(-1) -320 mL) compared with placebo (-130 mL). No effect on disease progression, DLCO, infection rates or mortality was observed. SGRQ scores showed a nonsignificant trend toward worsening with active treatment. Unexpectedly, free CC-chemokine ligand 2 levels were elevated above baseline at both 24 and 52 weeks. A higher proportion of patients with one or more serious adverse events was observed in the 5 mg·kg(-1) group (53.1%) compared with 1 mg·kg(-1) (15.2%), 15 mg·kg(-1) (21.9%) and placebo (46.4%), although no unexpected serious adverse events were noted.Although dosing was stopped prematurely, it is unlikely that carlumab provides benefit to IPF patients.

RESUMO

There is an association with acute viral infection of the respiratory tract and exacerbations of asthma and chronic obstructive pulmonary disease (COPD). Although these exacerbations are associated with several types of viruses, human rhinoviruses (HRVs) are associated with the vast majority of disease exacerbations. Due to the lack of an animal species that is naturally permissive for HRVs to use as a facile model system, and the limitations associated with animal models of asthma and COPD, studies of controlled experimental infection of humans with HRVs have been used and conducted safely for decades. This review discusses how these experimental infection studies with HRVs have provided a means of understanding the pathophysiology underlying virus-induced exacerbations of asthma and COPD with the goal of developing agents for their prevention and treatment.

RESUMO

Patients with rare chronic disorders and their caregivers increasingly form communities to support and exchange social experiences. Because up to 10% of the United States population is affected by one of 5000 to 6000 rare disorders, efforts to understand the individuals and affected communities are important. This study was conducted using community-based participatory research approaches within a community of patients and caregivers living with alpha-1 antitrypsin (AAT) deficiency. Patient populations at some risk for lung transplant include individuals who smoked cigarettes and patients who underwent liver transplant in infancy and later adulthood due to accumulation of misfolded AAT within hepatocytes.

RESUMO

RATIONALE: There was an increased number of malignancies in infliximab-treated (5.7%) over placebo-treated (1.3%) patients in a 44-week, phase 2 clinical study of 234 patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). OBJECTIVES: To collect malignancy and mortality data from completed clinical studies of infliximab in COPD treatment. METHODS: The multicenter, observational Remicade Safety Under Long-Term Study in COPD (RESULTS COPD) collected malignancy and mortality data every six months for five years from patients who received ≥1 study-agent dose in a phase 2 study. Co-primary endpoints were the number of patients with malignancy and the number of deaths. Secondary endpoints included the number of patients with a malignancy according to malignancy type. RESULTS: There was a gap period between the end of the phase 2 study and the initiation of RESULTS COPD, during which six malignancies and 14 deaths were reported spontaneously for the 107 (45.7%) of 234 patients with long-term safety information. Twenty-eight patients (overall 12.0%; placebo 10.4%, infliximab 12.7%) reported malignancies, including 12 patients during RESULTS COPD. Twenty-six patients (overall 11.1%; placebo 9.1%, infliximab 12.1%) died, including nine during RESULTS COPD. Lung cancer was the most common malignancy type (placebo n = 2; infliximab n = 10). CONCLUSIONS: The greater proportion of malignancies observed with infliximab versus placebo in a phase 2 study diminished over the long-term follow-up. Due to the observational nature, limited patient participation, potential reporting bias from the interim spontaneous reporting period, and unblinding of all patients, more definitive conclusions cannot be drawn.

RESUMO

RATIONALE: Idiopathic pulmonary fibrosis (IPF) is a lethal lung disease of unknown etiology with a variable and unpredictable course. OBJECTIVES: The aim of this study was to identify and validate plasma proteins that are predictive of outcome in IPF. METHODS: Plasma samples were available for 241 patients with IPF (140 derivation and 101 validation). In the derivation cohort, concentrations of 92 proteins were analyzed using a multiplex bead-based immunoassay and concentrations of matrix metalloproteinase (MMP)-7, MMP-1, and surfactant protein D were assessed by ELISA. In the validation cohort concentrations of intercellular adhesion molecule (ICAM)-1, IL-8, and vascular cell adhesion molecule (VCAM)-1 were assessed by bead-based multiplex assay, and S100A12 and MMP-7 by ELISA. Associations of biomarkers with mortality, transplant-free survival, and disease progression were tested in the derivation and validation cohorts using nonparametric methods of survival analysis and the Cox proportional hazards model, and an integrated risk prediction score was derived and tested. MEASUREMENTS AND MAIN RESULTS: High concentrations of MMP-7, ICAM-1, IL-8, VCAM-1, and S100A12 predicted poor overall survival, poor transplant-free survival, and poor progression-free survival in the derivation cohort. In the independent validation cohort high concentrations of all five were predictive of poor transplant-free survival; MMP-7, ICAM-1, and IL-8 of overall survival; and ICAM-1 of poor progression-free survival. The personal clinical and molecular mortality prediction index derived in the derivation cohort was highly predictive of mortality in the validation cohort. CONCLUSIONS: Our results suggest that plasma proteins should be evaluated as a tool for prognosis determination in prioritization of patients for lung transplantation and stratification in drug studies.

RESUMO

Sarcoidosis is an inflammatory, granulomatous disease of unknown etiology that most commonly afflicts the lungs. Despite aggressive immunosuppressive therapies, many sarcoidosis patients still chronically present significant symptoms. Infliximab, a therapeutic tumor necrosis factor alpha (TNF-α) monoclonal antibody (MAb), produced a small but significant improvement in forced vital capacity (FVC) in sarcoidosis patients in a double-blind, placebo-controlled, phase II clinical trial. In the current study, serum samples from this clinical trial were assessed to evaluate the underlying hypothesis that treatment with infliximab would reduce systemic inflammation associated with sarcoidosis, correlating with the extent of clinical response. A 92-analyte multiplex panel was used to assess the expression of serum proteins in 134 sarcoidosis patients compared with sera from 50 healthy controls. A strong systemic inflammatory profile was associated with sarcoidosis, with 29 analytes significantly elevated in sarcoidosis (false-discovery rate, <0.05 and >50% higher than controls). The associated analytes included chemokines, neutrophil-associated proteins, acute-phase proteins, and metabolism-associated proteins. This profile was evident despite patients receiving corticosteroids and immunosuppressive therapies. Following infliximab treatment, sarcoidosis patients expressing the highest levels of TNF-α, who had more severe disease, had the greatest improvement in FVC and reduction in serum levels of the inflammatory proteins MIP-1ß and TNF-RII. This study supports the need for further exploration of anti-TNF therapy for chronic sarcoidosis patients, particularly for those expressing the highest serum levels of TNF-α.

RESUMO

BACKGROUND: The best method to interpret the chest roentgenogram and its sensitivity to detect effect of treatment for sarcoidosis remains unclear. In a double-blind, randomized trial of infliximab for chronic pulmonary sarcoidosis, changes in serial chest roentgenograms were examined by radiologists, blinded to order or treatment. METHODS: Chest roentgenograms were obtained at 0, 6, and 24 weeks of therapy with either placebo, 3 mg/kg infliximab, or 5 mg/kg infliximab. Films were reviewed in random order by two independent radiologists, unaware of treatment. The films were compared using two methods: the prespecified objective assessment, a scoring system previously proposed by Muers; and the post hoc assessment, a 5-point Likert scale global assessment between two films. RESULTS: Of 138 patients enrolled in the study, chest roentgenograms for all studies were available on 130 patients. There was only fair agreement between the two radiologists in the original stage of the chest roentgenogram (weighted kappa = 0.43; 95% confidence interval [CI], 0.32 to 0.54). For the Likert scale of global assessment of change, there was good agreement between the two readers (weighted kappa = 0.61; 95% CI, 0.51 to 0.71). There was good correlation between the two readers for the various components of the Muers score, especially the reticulonodular (R) score (R = 0.578; p < 0.05). The initial R score was positively correlated with improvement in FVC with infliximab therapy (R = 0.239; p < 0.05). CONCLUSION: Global assessment and the Muers scoring system were associated with good agreement between two expert readers. Improvement in both scores correlated with improvement in FVC.

RESUMO

There is a growing body of literature promoting the use of honey-based products in wound care, demonstrating their efficacy, cost-effectiveness and excellent record of safety. Thus, there has been a sizeable renaissance in the use of honey as a topical treatment for a wide range of wounds. This resurgence has brought an array of new honey-based wound products into the market place. Honey for the purposes of wound management has to be 'medical grade', which ensures that it has been sterilized by gamma irradiation and has a standardized antibacterial activity--only these honeys can be registered as medical devices. Hence, practitioners should exercise caution before using any unregulated unlicensed honey product as a treatment for wounds. This article provides healthcare practitioners with the information they need to make a considered decision when choosing between honey-based products. It highlights the importance of established clinical evidence in demonstrating the therapeutic properties of honey and supporting the use of honey-based products in the management of wounds. The practitioner needs to consider the written information provided by manufacturers as to the clinical evidence base of the product, indications and contraindications for use and safety of the product.

RESUMO

RATIONALE: Evidence suggests that tumor necrosis factor (TNF)-alpha plays an important role in the pathophysiology of sarcoidosis. OBJECTIVES: To assess the efficacy of infliximab in sarcoidosis. METHODS: A phase 2, multicenter, randomized, double-blind, placebo-controlled study was conducted in 138 patients with chronic pulmonary sarcoidosis. Patients were randomized to receive intravenous infusions of infliximab (3 or 5 mg/kg) or placebo at Weeks 0, 2, 6, 12, 18, and 24 and were followed through Week 52. MEASUREMENTS AND MAIN RESULTS: The primary endpoint was the change from baseline to Week 24 in percent of predicted FVC. Major secondary efficacy parameters included Saint George's Respiratory Questionnaire, 6-min walk distance, Borg's CR10 dyspnea score, and the proportion of Lupus Pernio Physician's Global Assessment responders for patients with facial skin involvement. Patients in the combined infliximab groups (3 and 5 mg/kg) had a mean increase of 2.5% from baseline to Week 24 in the percent of predicted FVC, compared with no change in placebo-treated patients (p = 0.038). No significant differences between the treatment groups were observed for any of the major secondary endpoints at Week 24. Results of post hoc exploratory analyses suggested that patients with more severe disease tended to benefit more from infliximab treatment. CONCLUSIONS: Infliximab therapy resulted in a statistically significant improvement in % predicted FVC at Week 24. The clinical importance of this finding is not clear. The results of this Phase 2 clinical study support further evaluation of anti-TNF-alpha therapy in severe, chronic, symptomatic sarcoidosis.

RESUMO

OBJECTIVE: Once-a-day dosing with nabumetone has been shown to be effective in adults with rheumatoid arthritis. We establish dosing recommendations for nabumetone in children and adolescents with juvenile rheumatoid arthritis (JRA). METHODS: An open label, multicenter study was conducted in children with JRA aged 2-16 years, weighing > 14 kg, and requiring nonsteroidal antiinflammatory drugs (NSAID) for control of symptoms. NSAID were discontinued one day prior to study initiation to minimize disease flare. Patients received nabumetone 30 mg/kg once daily (as a tablet or a slurry) for 12 weeks. Efficacy assessment evaluations were performed at Weeks 1, 3, 6, and 12, based on the mean change from baseline at the study endpoint for 6 standard rheumatology variables. An overall assessment of efficacy was determined based on the percentage of patients who did not experience a flare, using the 6 rheumatology variables. Since this was an open label study, only descriptive statistics were obtained for efficacy variables. Routine safety assessments were completed for all patients. RESULTS: In total, 99 patients with JRA were enrolled and 89 completed the study; mean age was 9.2 years. The proportion of nabumetone treated patients with no flare in disease activity during the nabumetone treatment period was 92/99 (93%). Improvement was noted in each efficacy assessment, although statistical evaluations were not performed. The adverse event profile was similar to that reported for nabumetone in adults with RA. CONCLUSION: Nabumetone 30 mg/kg/day (up to 2000 mg/day) demonstrated a safe profile with no loss of efficacy compared to previous treatment in children with JRA. The dose can be administered by suspending tablets in warm water to create a slurry.

RESUMO

Nonsteroidal anti-inflammatory drugs interfere with certain antihypertensive therapies. In a double-blind study, 385 hypertensive patients stabilized on an angiotensin converting enzyme inhibitor were treated with nabumetone, celecoxib, ibuprofen, or placebo for 4 weeks. Ibuprofen caused significantly greater increases in systolic (P < .001) and diastolic (P < .01) blood pressures (BPs) compared to placebo, but not nabumetone or celecoxib. The proportion of patients with systolic BP increases of clinical concern at end point was significantly higher (P < .001) for the ibuprofen group (16.7%; 15 of 90), but not for the nabumetone group (5.5%; 5 of 91) or the celecoxib group (4.6%; 4 of 87) compared to the placebo group (1.1%; 1 of 91).

RESUMO

Linezolid was provided for treatment of multidrug-resistant, gram-positive infections through a compassionate-use program. Patients (n=796) received 600 mg of linezolid intravenously or orally every 12 h (828 treatment courses). Bacteremia was present in 46% of infections, endocarditis was present in 10.6%, and line-related infections were present in 31.1%. Other infections included intraabdominal infections (15.1%), complicated skin and skin-structure infections (13.3%), and osteomyelitis (10.7%). Causative pathogens included vancomycin-resistant enterococci (66.3%) and methicillin-resistant staphylococci (22.1%). Clinical intent-to-treat (ITT) outcomes in the evaluable population were as follows: cure, 73.3%; failure, 6.8%; and indeterminate, 19.9%. Microbiological ITT outcomes in evaluable patients were as follows: cure, 82.4%; failure, 14.1%; and indeterminate, 3.5%. At the test of cure assessment, the clinical cure and microbiological success rates were 91.5% and 85.8%, respectively. The most common adverse events possibly related to linezolid use were gastrointestinal disturbances (9.8% of cases), thrombocytopenia (7.4% of cases), decreased hemoglobin/hematocrit levels (4.1% of cases), and cutaneous reactions (4.0% of cases). Linezolid provided high rates of clinical cure and microbiological success in this complicated patient population, with very good overall tolerance.

RESUMO

PURPOSE: To describe the attitudes and perceptions of body image of African American postpartum women, and the differences in these measures when body mass index (BMI) was considered. DESIGN: Descriptive comparative. METHODOLOGY: Secondary analysis of a larger study. The sample was 45 African American women. Body image was assessed using the Attitude to Body Image Scale (ABIS) and the topographic device. Participants were grouped according to BMI categories. Body image differences by BMI category were determined using ANOVA. RESULTS: The mean ABIS score for the total sample was 2.8 (range = 1.0-5.8). Although not statistically significantly different, the mean ABIS score for the overweight/obese group was 3.4 (SD = 0.42), for the normal weight group the mean score was 2.8 (SD = 0.22) and for the underweight group it was 2.6 (SD = 0.24). The mean amount of perceived space occupied was 30.0 while the mean amount of actual space occupied was 21.0 in (N = 45). When the perceptual component was assessed, all women, irrespective of size, considered themselves larger than they actually were. However, perceptions did not differ by body mass category. IMPLICATIONS: Nurses can use this information to plan culturally sensitive postpartum care relative to body image and weight. Healthcare providers may wish to develop interventions that foster healthy lifestyle behaviors, such as healthy eating habits, based on health promotion rather than on weight loss. With this caveat in mind, performing a 24-hr recall of foods eaten would be an appropriate assessment strategy.
