The Diagnosis of Concussion in Pediatric Emergency Departments: A Prospective Multicenter Study

Background

The accurate identification of children with a concussion by emergency physicians is important to initiate appropriate anticipatory guidance and management.

Recognizing Gynecological Cancer in Primary Care: Risk Factors,Red Flags,and Referrals

Early diagnosis of symptomatic gynecological cancer is likely to improve patient outcomes, including survival. The primary care practitioner has a key role to play in this—they must recognize the symptoms and signs of gynecological cancer and make prompt evidence-based decisions regarding further investigation and referral. However, this is often difficult as many of the symptoms of gynecological cancers are nonspecific and are more likely to be caused by benign rather than malignant disease. As primary care is generally the first point of patient contact, those working in this setting usually encounter cancer patients at an earlier, and possibly less symptomatic, stage than practitioners in secondary care. Despite these challenges, research has improved our understanding of the symptoms patients present to primary care with, and a range of tests and referral pathways now exist in the UK and other countries to aid early diagnosis. Primary care practitioners can also play a key role in gynecological cancer prevention. A significant proportion of gynecological cancer is preventable either through lifestyle changes such as weight loss, or, for cervical cancer, vaccination and/or engagement with screening programs. Primary care provides an excellent opportunity to discuss cancer risk with patients and to promote risk reduction strategies and lifestyle change. In this article, the first in a series discussing cancer detection in primary care, we concentrate on gynecological cancer and focus on the three most common forms that a primary care practitioner is likely to encounter: ovarian, endometrial, and cervical cancer. We outline key risk factors, briefly discuss prevention and screening strategies, and offer practical guidance on the recognition of symptoms and signs and the investigation and referral of women with suspected cancer. While this article is written from a UK primary care perspective, much of what is discussed will be of relevance to those working in other healthcare systems.     

Interrater and intrarater reliability of the wheelchair skills test version 4.2 for power wheelchair users

Purpose: The purpose of this study is to estimate the interrater and intrarater reliability of the Wheelchair Skills Test (WST) Version 4.2 for powered wheelchairs operated by adult users.

Materials and methods: Cohort study with a convenience sample of occupational therapists (n?=?10). For the main outcome measure, participants viewed and scored eight videos of adult power wheelchair users completing the 30 skills of the WST Version 4.2 on two occasions, a minimum of two weeks apart. Using these scores, we calculated intraclass correlation coefficients to estimate interrater and intrarater reliability.

Results: The interrater reliability intraclass correlation coefficient was 0.940 (95%CI 0.862–0.985). Intrarater reliability intraclass correlation coefficients ranged from 0.923 to 0.998.

Conclusions: The WST Version 4.2 has excellent interrater and intrarater reliability and is a reliable tool for use in clinical and research practice to evaluate a power wheelchair user’s skill capacity.

• Implications for Rehabilitation

• The Wheelchair Skills Test for Powered Wheelchair Users (WST-P 4.2) is a useful addition to the clinical tools available for clinicians who assess and train for powered wheelchair use.

• The WST-P 4.2 has excellent reliability and potential for clinical use as a pre-post measure of powered wheelchair skills.

• Clinicians using the WST-P 4.2 should attempt to maintain consistent scoring procedures, particularly for those skills that may require subjective assessment of skill safety.

     

Congruence Between Latent Class and K-Modes Analyses in the Identification of Oncology Patients With Distinct Symptom Experiences

Context

Risk profiling of oncology patients based on their symptom experience assists clinicians to provide more personalized symptom management interventions. Recent findings suggest that oncology patients with distinct symptom profiles can be identified using a variety of analytic methods.

Characteristics of Tuberculosis Cases that Started Outbreaks in the United States, 2002–2011

A review of 26 tuberculosis outbreaks in the United States (2002–2011) showed that initial source case-patients had long infectious periods (median 10 months) and were characterized by substance abuse, incarceration, and homelessness. Improved timeliness of diagnosis and thorough contact investigations for such cases may reduce the risk for outbreaks.     

Energy Intake,Profile, and Dietary Sources in the Spanish Population: Findings of the ANIBES Study

Energy intake, and the foods and beverages contributing to that, are considered key to understanding the high obesity prevalence worldwide. The relative contributions of energy intake and expenditure to the obesity epidemic, however, remain poorly defined in Spain. The purpose of this study was to contribute to updating data of dietary energy intake and its main sources from food and beverages, according to gender and age. These data were derived from the ANIBES (“Anthropometry, Intake, and Energy Balance in Spain”) study, a cross-sectional study of a nationally representative sample of the Spanish population (from 9–75 years old). A three-day dietary record, collected by means of a tablet device, was used to obtain information about food and beverage consumption and leftovers. The final sample comprised 2009 individuals (1,013 men, 996 women). The observed mean dietary energy intake was 7.6 ± 2.11 MJ/day (8.2 ± 2.22 MJ/day for men and 6.9 ± 1.79 MJ/day for women). The highest intakes were observed among adolescents aged 13–17 years (8.4 MJ/day), followed by children 9–12 years (8.2 ± 1.80 MJ/day), adults aged 18–64 (7.6 ± 2.14 MJ/day) and older adults aged 65–75 years (6.8 ± 1.88 MJ/day). Cereals or grains (27.4%), meats and derivatives (15.2%), oils and fats (12.3%), and milk and dairy products (11.8%) contributed most to daily energy intake. Energy contributions from non-alcoholic beverages (3.9%), fish and shellfish (3.6%), sugars and sweets (3.3%) and alcoholic beverages (2.6%) were moderate to minor. Contributions to caloric profile were 16.8%E from proteins; 41.1%E from carbohydrates, including 1.4%E from fiber; 38.5%E from fats; and 1.9%E from alcohol intake. We can conclude that energy intake is decreasing in the Spanish population. A variety of food and beverage groups contribute to energy intake; however, it is necessary to reinforce efforts for better adherence to the traditional Mediterranean diet.     

Distinct Neuropsychological Mechanisms May Explain Delayed- Versus Rapid-Onset Antidepressant Efficacy

The biochemical targets for antidepressants are relatively well established, but we lack a clear understanding of how actions at these proteins translate to clinical benefits. This study used a novel rodent assay to investigate how different antidepressant drugs act to modify affective biases that have been implicated in depression. In this bowl-digging task, rats encounter two equal value learning experiences on separate days (one during an affective manipulation and the other during control conditions). This induces an affective bias that is quantified using a preference test in which both digging substrates are presented together and the individual rats’ choices recorded. The assay can be used to measure affective biases associated with learning (when the treatment is given at the time of the experience) or examine the modification of previously acquired biases (when the treatment is administered before the preference test). The rapid-onset antidepressant ketamine, but not the delayed-onset antidepressant, venlafaxine, attenuated the previously acquired FG7142-induced negative bias following systemic administration. Venlafaxine but not ketamine induced a positive bias when administered before learning. We then used local drug infusions and excitotoxic lesions to localize the effects of ketamine to the medial prefrontal cortex and venlafaxine to the amygdala. Using a modified protocol we also showed that positive and negative biases amplified further when the numbers of substrate–reinforcer associations are increased. We propose that this pattern of results could explain the delayed onset of action of venlafaxine and the rapid onset of action but lack of long-term efficacy seen with ketamine.
