Prejudice and the Plate: Effects of Weight Bias in Nutrition Judgments

As millions of people turn to social media for health information, better understanding the factors that guide health-related judgments and perceptions in this context is imperative. We report on two Web experiments (n > 400 total) examining the power of society’s widespread weight bias and related stereotypes to influence nutrition judgments in social media spaces. In Experiment 1, meals were judged as lower in nutritional quality when the person who recommended them (the source) was depicted as obese rather than of normal weight, an effect mediated by stereotypic beliefs about the source as a generally unhealthy person. Experiment 2 replicated this effect, which—notably—remained significant when controlling for objective nutritional information (calories and fat content). Results highlight spillover effects of weight bias that extend beyond person perception to color impressions of objects (here, food) that are associated with stigmatized attributes. Implications for everyday nutrition judgments and public health are considered.     

Negative symptoms in schizophrenia: considerations for clinical trials

There is little agreement about the methodology of clinical trials of antipsychotic drugs in patients with negative symptoms. A literature review revealed wide variation in experimental design, rating scales and study duration. This reflects differing views as to the definition and response to treatment of negative symptoms. Some degree of standardization would improve comparability of studies and aid the development of new compounds. Patients included in such studies should have displayed negative symptoms for at least 6 months. Depressive symptoms, positive schizophrenic symptoms and extrapyramidal signs may all influence or be confused with negative symptoms and may respond to treatment; they should be at a low level at baseline and should be measured during the study period. Studies should last at least 8 weeks. Several scales are available for measuring negative symptoms and are reviewed; a global impression score should be used additionally.     

Life-threatening asthma and anaphylaxis in schools: a treatment model for school-based programs.

BACKGROUND: Pediatric asthma is the No. 1 chronic disease in childhood and is responsible for significant morbidity and mortality. In Nebraska, the number of asthma-related deaths is greater than the national average, and in 1998, 2 students died of acute asthma attacks while attending school in the Omaha public schools (OPSs). In response, we designed and implemented a program to respond to this problem. OBJECTIVE: To implement and study a school-based program for the treatment of life-threatening asthma and anaphylaxis in the OPSs. METHODS: The Emergency Response to Life-Threatening Asthma or Systemic Allergic Reactions (Anaphylaxis) Protocol was designed and evaluated in 78 OPSs from 1998 to 2003. Nurses and school staff were trained in the protocol, which required the use of nebulized albuterol and/or intramuscular epinephrine in conjunction with an emergency response procedure. Outcomes were measured by improvement in acute care in schools and survival of students. Results: In the 5 years of evaluation, 98 students were treated successfully. One student died. Of those treated with the protocol, equal numbers had at school both asthma action plans (AAPs) and metered-dose inhalers (MDIs), MDIs only, or neither AAPs nor MDIs. As a result of the program, there has been an increased awareness from parents, teachers, and physicians about the necessity of an emergency response program. In 2002, an outcome of the OPS program resulted in the formation of Attack on Asthma Nebraska to ensure that Nebraska schools have the education, training, and medications to respond to anyone experiencing a life-threatening asthma or anaphylaxis attack at school. The following year, a revised protocol was approved by the Nebraska State Board of Education for use in all Nebraska schools. CONCLUSIONS: Emergency response protocols provide protection for children while in school. This program should serve as a national model for other school-based programs for children and adolescents with asthma and anaphylaxis.     

Use of lung resection and voriconazole for successful treatment of invasive pulmonary Aspergillus ustus infection

Invasive pulmonary aspergillosis (IPA) is a common infection in neutropenic patients and is associated with high mortality. Aspergillus ustus is a species that has only rarely been implicated in human disease. All reported cases of IPA due to A. ustus have been fatal. Here, we describe a case of invasive pulmonary A. ustus infection successfully treated with lung resection and voriconazole. A 43-year-old man with acute myeloid leukemia underwent two courses of chemotherapy and experienced prolonged neutropenia. Treatment with amphotericin B was given for persistent fever. While he was receiving amphotericin B, a progressive opacity developed in the upper right lobe. Lung tissue obtained through pulmonary wedge resection for histology showed a mold with septate hyphae, consistent with IPA due to Aspergillus. A. ustus was grown in culture. The patient was then treated with voriconazole and remained in remission of the mold infection in spite of additional chemotherapy and a leukemic relapse. In summary, this report describes the successful treatment of invasive pulmonary A. ustus infection by lung resection and antifungal treatment with voriconazole in a neutropenic patient.     

Solid tumors in patients treated for Hodgkin's disease: a report from the German Hodgkin Lymphoma Study Group.

BACKGROUND: Long-term survivors of successfully treated Hodgkin's disease (HD) are at risk for late complications. Among these, secondary solid tumors are most serious because they are often fatal. The aim of this retrospective analysis was to assess the incidence, relative risk and risk factors of secondary solid tumors in HD patients registered in the database of the German Hodgkin Lymphoma Study Group (GHSG). PATIENTS AND METHODS: From 1983 to 1998, the GHSG conducted three generations of clinical trials for early, intermediate and advanced stage HD (HD1-HD9) involving a total of 5367 patients. Data on incidence, risk factors and relative risk were updated in March 2003. RESULTS: A total of 127 patients with secondary solid tumors were identified. Among these, lung cancer (23.6%), colorectal cancer (20.5%) and breast cancer (10.2%) were the most frequent. After a median follow-up of 72 months the cumulative risk of developing a solid tumor was 2%, with an overall relative risk (RR) of 2.4 (lung cancer, 3.8; colorectal cancer, 3.2; breast cancer, 1.9). For most patients (n=67; 52.8%) developing a secondary solid tumor, treatment modality consisted of chemotherapy combined with radiotherapy in extended field technique (RR = 3.3). CONCLUSIONS: With a median follow-up of 72 months, there were 127 patients developing solid tumors out of a total of 5367 HD patients treated in the GHSG studies HD1-HD9. The cumulative risk of 2% is expected to increase over time due to the rather short median observation time and slow progression of solid malignancies.     

Prevalence of nosocomial infections in Swiss children's hospitals.

OBJECTIVE: To acquire data on pediatric nosocomial infections (NIs), which are associated with substantial morbidity and mortality and for which data are scarce. DESIGN: Prevalence survey and evaluation of a new comorbidity index. SETTING: Seven Swiss pediatric hospitals. PATIENTS: Those hospitalized for at least 24 hours in a medical, surgical, intensive care, or intermediate care ward. RESULTS: Thirty-five NIs were observed among 520 patients (6.7%; range per hospital, 1.4% to 11.8%). Bacteremia was most frequent (2.5 per 100 patients), followed by urinary tract infection (1.3 per 100 patients) and surgical-site infection (1.1 per 100 patients; 3.2 per 100 patients undergoing surgery). The median duration until the onset of infection was 19 days. Independent risk factors for NI were age between 1 and 12 months, a comorbidity score of 2 or greater, and a urinary catheter. Among surgical patients, an American Society of Anesthesiologists (ASA) score of 2 or greater was associated with any type of NI (P = .03). Enterobacteriaceae were the most frequent cause of NI, followed by coagulase-negative staphylococci; viruses were rarely the cause. CONCLUSIONS: This national prevalence survey yielded valuable information about the rate and risk factors of pediatric NI. A new comorbidity score showed promising performance. ASA score may be a predictor of NI. The season in which a prevalence survey is conducted must be considered, as this determines whether seasonal viral infections are observed. Periodic prevalence surveys are a simple and cost-effective method for assessing NI and comparing rates among pediatric hospitals.     

THE BIOLOGICAL BASIS OF BEHAVIORAL SYMPTOMS IN DEMENTIA

This article describes the pathophysiology of dementia and differentiates between cognitive and noncognitive symptoms that characterize this devastating illness. Relationships between brain anatomic and neurochemical systems and behavioral symptoms of dementia are discussed. An overview of the etiologies and neuropathologies of dementia are presented as they relate to impairments in memory and intellectual abilities, personality changes, and behavioral symptoms. Recent genetic and molecular discoveries that have advanced our understanding of this complex spectrum of disorders and their treatment(s) are also highlighted.
