AI Article Synopsis
- Measuring blood pressure accurately relies on using the correct cuff size based on mid-arm circumference (mid-AC), which varies among different populations in the U.S.
- The study analyzed data from over 24,000 individuals aged 3 years and older, revealing that mean mid-AC remained stable from 2011 to 2016, with notable differences by gender, age, and ethnicity.
- A significant percentage of teens and adults required larger BP cuffs, with associations between higher body mass index (BMI) and increased mid-AC, suggesting that managing cuff sizes is vital for accurate blood pressure readings.
Article Abstract
Background: Measuring blood pressure (BP) requires an appropriate BP cuff size given measured mid-arm circumference (mid-AC).
Objective: To provide mid-AC means and percentiles for US population aged more than 3 years and examine the frequency distribution of mid-AC cuffed by Baum and Welch Allyn cuff systems.
Patients And Methods: The 2011-2016 National Health and Nutrition Examination Survey, a cross-sectional survey, was used to estimate mean mid-AC (n=24 723).
Results: Mean mid-AC did not differ from 2011 to 2016 (31.0 vs. 31.3 cm, P>0.05). During 2011-2016, mean mid-AC was greater for males than females (32.0 vs. 30.4 cm, P<0.001) and was largest among adults 40-49 years (34.0 cm). Non-Hispanic Black persons had the largest mean mid-AC (32.0 cm) and non-Hispanic Asian persons the smallest (28.4 cm). Increased BMI was associated with increased mean mid-AC for those 3-19 years (normal, 22.0 cm and obese, 31.5 cm, P<0.001) and more than 20 years (normal, 28.2 cm and obese, 37.8 cm, P<0.001). Among those aged 8-17 years, high BP status was associated with a larger mean mid-AC (normotensive 26.1 cm vs. high BP 28.2 cm, P=0.001). Among adults aged 18 years and older, hypertension status was associated with a larger mean mid-AC (normotensive 32.4 cm vs. hypertensive 34.2 cm, P<0.001). Among those aged 12-19 years, 13.0% required a Baum large cuff (35-46.9 cm mid-AC) and 21.7% required a Welch Allyn large cuff (32-39.9 cm mid-AC). Among those aged more than 20 years, 33.2% required a Baum large cuff, 48.2% required a Welch Allyn large cuff, 1.3% required a Baum extra-large cuff (44-66 cm mid-AC), and 9.5% required a Welch Allyn extra-large cuff (40-55 cm mid-AC).
Conclusion: Currently, BP is obtained in clinic, pharmacy, home, and ambulatory setting using single or multiple cuffs. National Health and Nutrition Examination Survey mid-AC data should be considered for accurate cuffing avoiding cuff hypertension or hypotension.

Phase angle is a useful predicting indicator for protein-energy wasting and cardiovascular risk among maintenance hemodialysis patients.

Article Synopsis
- Protein-energy wasting (PEW) significantly increases mortality rates in maintenance hemodialysis (MHD) patients, especially due to cardiovascular disease (CVD), which is a leading cause of death in this group.
- Our study aimed to evaluate the predictive value of phase angle (PA), measured via bioelectrical impedance analysis (BIA), in assessing PEW and cardiovascular risk in MHD patients.
- Using LASSO logistic regression on data from 161 patients, we found that a combination of PA and other body composition metrics could better predict PEW incidence than any single factor, showing a strong correlation between low PA and higher cardiovascular risk.*

When the time since death must be calculated forensic pathologists often consider a calculation based on the Henssge nomogram. This calculation requires an estimated body weight. Previous research has indicated that healthcare workers generally inaccurately guessed patients' body weights.

Background: Body weight is an important parameter for estimating the postmortem interval (PMI) at a crime scene. However, a challenge arises at crime scenes when a weight scale for measuring the total body weight is unavailable. Anthropometry-based models to estimate body weight have been developed in previous studies.

Article Synopsis
- A study of 1,176 pregnant women aimed to identify the proportion needing different blood pressure cuff sizes—small adult, adult, large, and extra-large—based on arm circumference, following American Heart Association guidelines.* -
- Results showed that 25.1% of women required large or XL cuffs, with higher needs identified among non-Hispanic Black women (38.5%) and those in the highest BMI quartile (81.8%).* -
- The study concluded that accurate cuff sizing is crucial for effective blood pressure monitoring and hypertension management in pregnant women.*

Background: The benefits and harms of protein-restricted diets supplemented with ketoanalogues in patients with chronic kidney disease (CKD) remain uncertain. We aimed to evaluate the effects of ketoanalogues supplemented to protein-restricted diets in patients with advanced CKD.
Methods: We conducted systematic literature searches of PubMed, Embase, Scopus, and Cochrane Library up to June 3, 2024.
