BackgroundFrailty is a state of vulnerability to stressors that is prevalent in older adults and is associated with higher morbidity, mortality and healthcare utilization. Multiple instruments are used to measure frailty; most are time-consuming. The Care Assessment Need (CAN) score is automatically generated from electronic health record data using a statistical model. The methodology for calculation of the CAN score is consistent with the deficit accumulation model of frailty. At a 95 percentile, the CAN score is a predictor of hospitalization and mortality in Veteran populations. The purpose of this study was to validate the CAN score as a screening tool for frailty in primary care.MethodsThis is a cross-sectional, validation study compared the CAN score with a 40-item Frailty Index reference standard based on a comprehensive geriatric assessment. We included community-dwelling male patients over age 65 from an outpatient geriatric medicine clinic. We calculated the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of the CAN score.Results184 patients over age 65 were included in the study: 97.3% male, 64.2% White, 80.9% non-Hispanic. The CGA-based Frailty Index defined 14.1% as robust, 53.3% as prefrail and 32.6% as frail. For the frail, statistical analysis demonstrated that a CAN score of 55 provides sensitivity, specificity, PPV and NPV of 91.67, 40.32, 42.64 and 90.91% respectively whereas at a score of 95 the sensitivity, specificity, PPV and NPV were 43.33, 88.81, 63.41, 77.78% respectively. Area under the receiver operating characteristics curve was 0.736 (95% CI = .661–.811).ConclusionCAN score is a potential screening tool for frailty among older adults; it is generated automatically and provides acceptable diagnostic accuracy. Hence, the CAN score may be a useful tool to primary care providers for detection of frailty in their patient panels.Electronic supplementary materialThe online version of this article (10.1186/s12877-018-0802-7) contains supplementary material, which is available to authorized users.

Background: HIV associated neurocognitive dysfunction (HAND) ranges from asymptomatic neurocognitive impairment (ANI) to mild neurocognitive disorders (MND) to HIV associated dementia (HAD). Cognitive impairment may impact medication adherence which will ultimately affect morbidity and mortality. Aim: This study was undertaken to evaluate neurocognitive dysfunction among HIV positive patients using the International HIV Dementia scale(IHDS). Materials and Methods: This cross sectional study was conducted in a tertiary care hospital attached to a medical college that caters to a large number of HIV positive patients. The subjects for this study included HIV positive patients belonging to WHO stage 1 or 2. Data collection was done using a pre tested questionnaire. The International HIV Dementia scale(IHDS) was used to assess HAND. Results: Out of the 101 patients studied, 69(68.3%) were males and 32(31.7%) were females. Among these patients, 88 (87.1%) were receiving antiretroviral therapy (ART), 84 (83.2%) were in WHO stage 1. 91 (90.1%) patients had HAND. There were statistically significant differences in the gender and educational level between patients with or without HAND. As age advanced the percentage of patients having HAND also increased. Conclusion: There was high prevalence of HIV associated neurocognitive dysfunction among HIV positive individuals in our study. Also there was an increase in HIV associated neurocognitive dysfunction with increase in age. DOI: http://dx.doi.org/10.3126/ajms.v5i4.8724 Asian Journal of Medical Sciences 2014 Vol.5(4); 61-64

Carotid webs are abnormal luminal projections at the carotid bulb associated with blood flow stasis, artery dissection, and subsequent complications. Carotid webs are considered to be a rare variant of fibromuscular dysplasia (FMD). Young individuals with symptomatic carotid webs are found to be associated with ischemic stroke. The incidence of the carotid web is low, and it is rarely reported. Only 150 cases of FMD have been reported so far. FMD is a noninflammatory and non-atherosclerotic arteriopathy. The most common arterial beds involved are renal and extracranial carotids. Presentation varies depending on the location of the arterial bed involved and disease severity. Clinical presentations range from minor headaches to severe headaches, resistant hypertension, acute coronary syndrome, transient ischemic attack, and in some cases, stroke. Diagnosis can be made through non-invasive methods, such as computed tomographic angiography, magnetic resonance angiography, or duplex ultrasonography or invasive imaging methods like catheter-based angiography. Treatment of FMD varies with disease presentation and its location. Asymptomatic carotid or vertebral arteries FMD should be monitored clinically and prescribed aspirin 81 mg daily for primary stroke prevention. Endovascular and surgical therapy with stents or coils is reserved for patients with aneurysms. We present a rare and interesting case of a 54-year-old female who presented with acute ischemic stroke in the setting of right carotid artery web, right internal carotid artery (ICA) thrombus with dissection, and possible pseudoaneurysm.
