RESUMO
Elderly patients with coronary artery disease have a high prevalence of frailty and malnutrition. Frailty syndrome is associated with poor outcomes in patients with myocardial infarction. There is a known overlap between frailty and malnutrition, yet these are two different entities. Fried Frailty Phenotype, Frail Scale, timed up and go test, and gait speed are rapid screening tests that may identify patients with frailty in everyday clinical setting. Short Form MNA is a sensitive tool to screen for malnutrition. Despite the availability of several tools for screening for both these conditions, the screening rates remain low. We aim to create awareness about the impacts of frailty and malnutrition, provide a brief overview of tools available and highlight the importance of screening in this high-risk population.
RESUMO
OBJECTIVES: To understand the prevalence of malnutrition and its association with chronic limb-threatening ischemia (CLTI) outcomes; to clarify the differential impact of revascularization methods on outcomes; to assess the ability of the CLTI Frailty Risk Score (CLTI-FRS) to predict adverse events in patients hospitalized with CLTI. BACKGROUND: Despite advances in the management of CLTI, a majority still undergo major amputation, and a minority heal within 6 months. There is a lack of validated assessment tools for the identification and management of frailty and malnutrition in these patients. METHODS: Using the National Inpatient Sample from January 2012 to September 2015, we identified all patients with CLTI using International Classification of Diseases Ninth Edition Clinical Modification codes. The cohort was divided into three groups according to nutritional status. Multivariable regression analysis was used to analyze the interaction between malnutrition and outcomes of interest. RESULTS: Of 1,414,080 CLTI-related hospitalizations, 163,835 (11.6%) were malnourished, 332,855 (23.5%) patients were frail, 917,390 (64.9%) were well-nourished. In-hospital mortality, major amputation, the average length of stay, and hospital costs were highest among malnourished or frail patients and lowest in well-nourished patients (p < 0.001). Malnourished and frail patients were observed to have lower rates of mortality with endovascular revascularization as compared to surgical (adjusted odds ratios: 0.675 [0.533-0.854; p = 0.001]). CONCLUSION: Many patients with CLTI are malnourished or frail, and this is associated with mortality and amputation. Both malnourished and frail patients were observed to have a mortality benefit with a less invasive approach to revascularization. Better assessment of nutritional and frailty status of CLTI patients may guide therapy and help prevent amputation and death.

OBJECTIVES: To investigate the effect of TAVR technique on in-hospital and 30-day outcomes in patients with aortic stenosis (AS) and reduced ejection fraction (EF). BACKGROUND: Patients with AS and concomitant low EF may be at risk for adverse hemodynamic effects from general anesthesia utilized in transcatheter aortic valve replacement (TAVR) via the conventional strategy (CS). These patients may be better suited for the minimally invasive strategy (MIS), which employs conscious sedation. However, data are lacking that compare MIS to CS in patients with AS and concomitant low EF. METHODS: In this retrospective study, we identified all patients with low EF (<50%) undergoing transfemoral MIS-TAVR vs CS-TAVR between March 2011 and May 2018. Our primary endpoint was defined as the composite of in-hospital mortality and major periprocedural bleeding or vascular complications. RESULTS: Two hundred and seventy patients had EF <50%, while 154 patients had EF ≤35%. Overall, a total of 236 patients were in the MIS group and 34 were in the CS group. Baseline characteristics between the two groups were similar except for Society of Thoracic Surgeons (STS) score (MIS 8.4 ± 5.1 vs CS 11.7 ± 6.8; P<.01). There were no differences between the two groups in incidence of the primary endpoint (MIS 5.5% vs CS 8.8%; odds ratio for MIS, 0.60; 95% confidence interval, 0.16-2.23; P=.45). CONCLUSIONS: In patients with severe AS and reduced EF, MIS was not associated with adverse in-hospital or 30-day clinical outcomes compared with CS. In these patients, MIS may be a suitable alternative to CS without compromising clinical outcomes.

While the field of endovascular interventions has evolved in the last decade, technological advancements have rendered drug-coated balloons (DCBs) to be the first line therapy for femoropopliteal artery disease. As the knowledge continues to advance, the application of DCB to the infrapopliteal segments as well as its role in in conjunction with plaque modification to minimize stent utilization, will be further elucidated.

The maintenance of balance and posture is a result of the collaborative efforts of vestibular, proprioceptive, and visual sensory inputs, but a fourth neural input, audition, may also improve balance. Here, we tested the hypothesis that auditory inputs function as environmental spatial landmarks whose effectiveness depends on sound localization ability during ambulation. Eight blindfolded normal young subjects performed the Fukuda-Unterberger test in three auditory conditions: silence, white noise played through headphones (head-referenced condition), and white noise played through a loudspeaker placed directly in front at 135 centimeters away from the ear at ear height (earth-referenced condition). For the earth-referenced condition, an additional experiment was performed where the effect of moving the speaker azimuthal position to 45, 90, 135, and 180° was tested. Subjects performed significantly better in the earth-referenced condition than in the head-referenced or silent conditions. Performance progressively decreased over the range from 0° to 135° but all subjects then improved slightly at the 180° compared to the 135° condition. These results suggest that presence of sound dramatically improves the ability to ambulate when vision is limited, but that sound sources must be located in the external environment in order to improve balance. This supports the hypothesis that they act by providing spatial landmarks against which head and body movement and orientation may be compared and corrected. Balance improvement in the azimuthal plane mirrors sensitivity to sound movement at similar positions, indicating that similar auditory mechanisms may underlie both processes. These results may help optimize the use of auditory cues to improve balance in particular patient populations.

OBJECTIVES/HYPOTHESIS: In the United States, falls are the leading cause of accidental deaths in adults aged over 65 years. Epidemiologic studies indicate that there is a correlation between hearing loss and the risk of falling among older people. The vestibular, proprioceptive, and visual systems are known to contribute to postural stability, but the contribution of audition to maintaining balance has not yet been determined. STUDY DESIGN: Cross-sectional study to measure postural stability in bilateral hearing-aid users aged over 65 years in aided and unaided conditions. METHODS: Balance was assessed using the Romberg on foam test and the tandem stance test. Tests were administered in the presence of a point-source broadband white-noise sound (0-4 kHz) source in both unaided and aided conditions in the dark. Subjective measures of balance were made using the Activities-specific Balance Confidence Scale. RESULTS: Performance was significantly better in the aided than the unaided condition (P = 0.005 for both tests). No statistically significant relationship between improvement in balance, and hearing was identified. Participants did not report that they perceived a difference in balance between the two conditions. CONCLUSION: These results indicate that hearing aids are a novel treatment modality for imbalance in older adults with hearing loss and suggest that wearing hearing aids may offer a significant public-health benefit for avoiding falls in this population.
