Background: African-American college students are less likely to meet recommended physical activity guidelines to promote health, and are at risk of overweight, obesity, and elevated blood pressure. Text messaging is an emerging international technology shown to engage college students, promote physical activity, and reduce health risks.
Purpose: To determine the feasibility of using text messaging to promote physical activity among African-American college students enrolled in a unique course focusing on lifestyle behaviors for a healthy heart.
Sample: A purposive sample of 11 (n=4 male, n=7 female) African-American college students aged 18-25 years with cell phones capable of receiving messages was used in this study.
Methods: A three-week text-message protocol was piloted using web-based software to evaluate feasibility with post-hoc grouping of participants into responders and non responders. Descriptive statistics and Mann-Whitney U-tests were used to analyze group differences.
Results: There was an attrition rate of nearly 91%. Observed engagement was 50% among responders with compliance at 44.44%. Observed engagement and compliance rates were less than 2% among nonresponders. There were no statistically significant differences in underlying variable distributions between groups. Of practical importance, it was noted that prior to texting responder means were higher for walking physical activity, and lower for body mass index, while nonresponders had higher means for vigorous physical activity.
Conclusion: The literature review indicated that text messaging is a cost-effective technology that can be incorporated into health education courses on HBCU campuses, but this project suggested semester timing is pivotal to feasibility. Implications largely address tailoring text messages to maintain engagement and evaluating the effect of text messages on physical activity level, body mass index, and blood pressure.

Experience with sodium glucose cotransporter-2 inhibitors in adult patients with Fontan circulation.
Adv Clin Exp Med
January 2025
Institute of Cardiology, Jagiellonian University Medical College, Cracow, Poland.
Background: We still know little about the effective pharmacological treatment of heart failure (HF) associated with the Fontan circulation. One of the new options may be sodium glucose cotransporter-2 inhibitors (SGLT2i), which have been proven effective in classic forms of left ventricular HF.
Objectives: To evaluate the effect and safety of SGLT2i inclusion in adults with Fontan circulation.
Background And Aims: Body composition parameters associated with aerobic fitness, mirrored by maximal oxygen consumption (V̇Omax), have recently gained interest as indicators of physical efficiency in facioscapulohumeral dystrophy (FSHD). Bioimpedance analysis (BIA) allows a noninvasive and repeatable estimate of body composition but is based on the use of predictive equations which, if used in cohorts with different characteristics from those for which the equation was originally formulated, could give biased results. Instead, the phase angle (PhA), a BIA raw bioelectrical parameter reflecting body fluids distribution, could provide reliable data for such analysis.

Pregnancy issues such as gestational hypertension, preeclampsia, and gestational diabetes mellitus (GDM) are significant contributors to long-term cardiovascular diseases (CVDs) in women. Recent research has proved the impact of exercise on improving cardiovascular outcomes, particularly in women with pregnancy-related disorders. This review explores the outcomes of various exercise interventions on cardiovascular health in pregnant women.

Graduate School of Health Sciences, Morinomiya University of Medical Sciences, Osaka, Japan.
Objective: To investigate whether there is a difference in hardness and hemoglobin concentration changes in the infrapatellar fat pad (IFP) during isometric quadriceps exercise (IQE) in patients with knee osteoarthritis (KOA) between those with and without knee extension limitation.
Design: In this cross-sectional study, data were collected at an orthopedic clinic from March 2022 to April 2023. Among patients diagnosed with KOA, those with knee joint extension range of motion <0° and >0° were defined as the limited group (n = 16) and non-limited group (n = 13), respectively.
