Storage of feature conjunction in transient auditor memory

The purpose of this study was to determine whether feature conjunction are stored in transient auditory memory. The mismatch negativity (MMN), an event-related potential that is elicited by stimuli that differ from a series of preceding stimuli was used in this endeavour. A tone that differed from the preceding series of stimuli in the conjunction of tow of its features, both present in preceding stimuli but in different combination, was found to elicit the MMN, the data are interpreted to indicate that information about the conjunction of feature is stored in the memory.     

Derm Access: A New Triage System to Rapidly Identify Suspicious Skin Lesions

BACKGROUND: Many screening programs have been implemented for the general population; however, dermatology appointment wait times continue to be long. Changes in scheduling would allow patients with suspicious skin lesions access to more immediate care. OBJECTIVES: The objective was to introduce a method for decreasing dermatology appointment wait times to allow patients with a high-risk skin lesion to be seen in a more efficient manner. METHODS: A telephone screening method was developed to allow for the most suspicious lesions to be seen within 72 hours if the patient wished to do so; appointment time slots were left open in physician schedules to accommodate these patients; and wait time, procedure, and treatment data were collected and compared against national wait time data. RESULTS: A total of 233 patients were seen during this study. A total of 146 of these patients were diagnosed with a cancerous or precancerous lesion. This was 63% of the total study population. The mean wait time in actual working days was 7.44 for this same period. CONCLUSION: This program substantially decreased patient anxiety, increased patient satisfaction, increased public relations for the practice, and increased public awareness of skin cancer. The Derm Access strategy can be implemented in any practice to reduce wait times for suspicious skin lesions.     

The Role of Parents in Public Views of Strategies to Address Childhood Obesity in the United States

Policy Points

• The American public—both men and women and those with and without children in the household—holds parents highly responsible and largely to blame for childhood obesity.
• High attributions of responsibility to parents for reducing childhood obesity did not universally undermine support for broader policy action. School-based obesity prevention policies were strongly supported, even among those viewing parents as mostly to blame for childhood obesity.
• Americans who viewed sectors outside the family (such as the food and beverage industry, schools, and the government) as helping address childhood obesity were more willing to support a wider range of population-based obesity prevention policies.

Context

The public''s views of parents’ behaviors and choices—and the attitudes held by parents themselves—are likely to influence the success of efforts to reverse obesity rates.

Methods

We analyzed data from 2 US national public opinion surveys fielded in 2011 and 2012 to examine attributions of blame and responsibility to parents for obesity, both among the general public and parents themselves, and we also explored the relationship between views of parents and support for obesity prevention policies.

Findings

We found that attribution of blame and responsibility to parents was consistently high, regardless of parental status or gender. Support for policies to curb childhood obesity also did not differ notably by parental status or gender. Multivariable analyses revealed consistent patterns in the association between public attitudes toward parents’ responsibility and support for policies to curb childhood obesity. High parental responsibility was linked to higher support for school-targeted policies but generally was not associated with policies outside the school setting. Attribution of greater responsibility to entities external to children and their parents (schools, the food and beverage industry, and the government) was associated with greater support for both school-targeted and population-based obesity prevention policies.

Conclusions

Our findings suggest that the high attribution of responsibility to parents for reducing childhood obesity does not universally undermine support for broader policy action. But appealing to parents to rally support for preventing obesity in the same way as for other parent-initiated social movements (eg, drunk driving) may be challenging outside the school setting.     

Toward a Broader View of Values in Cost-Effectiveness Analysis of Health

By registering different health benefits on a common scale, CEA allows us to assess the relative social importance of different health care interventions and opens the way for the allocation decisions of health care policy. If it is really to be effective, however, CEA must be recalibrated so that it better reflects some of our widely held beliefs about the merits of different kinds of treatment.     

Development and validation of a multidimensional instrument for assessing outcome of treatment among opiate users: the Opiate Treatment Index

This article presents a new instrument with which to assess the effects of opiate treatment. The Opiate Treatment Index (OTI) is multi-dimensional in structure, with scales measuring six independently measured outcome domains: drug use; HIV risk-taking behaviour; social functioning; criminality; health; and psychological adjustment. Psychometric properties of the Index are excellent, suggesting that the OTI is a relatively quick, efficient means of obtaining reliable and valid data on opiate users undergoing treatment over a range of relevant outcome domains.     

Atrial Evoked Response Integral for Automatic Capture Verification in Atrial Pacing

BORIANI, G., et al.: Atrial Evoked Response Integral for Automatic Capture Verification in Atrial Pacing . Beat-by-beat Autocapture is currently limited to operation in the ventricle with bipolar leads. The authors investigated the integral of the negative-going portion of the atrial evoked response integral (AERI) as a potential resource for verification of atrial capture. Intracardiac electrogram signals were collected from 59 patients (ages 67.8 ± 15.1 years) with bipolar, low polarization atrial leads. The signals were collected over a mean period of 6.1 months (minimum 4 days) after lead implantation. St. Jude Medical Affinity pulse generators were used to perform automatic capture threshold tests while the electrogram signals were recorded by a Model 3510 programming device. These signals were transferred to a personal computer in digital form for later analysis. The AERI was calculated at each programmable pacing voltage until capture was lost. The difference between the polarization integral at loss of capture and evoked response integral with successful capture was sufficient to justify enabling the atrial Autocapture feature in 53 of 59 patients in whom bipolar pacing and unipolar sensing was performed. The authors developed a calibration routine to identify automatically those patients in whom atrial Autocapture could be programmed On, based on the polarization integral at loss of capture, the estimated maximum polarization integral, and the AERI. Preliminary analysis indicated that the AERI is a practical resource for beat-by-beat atrial capture detection when used with low polarization leads. (PACE 2003; 26[Pt. II]:248–252)
