Unveiling the interplay between rational, psychological and functional factors in continuous glucose monitoring early adoption: Novel evidence from the Dexcom ONE case in Italy.

BACKGROUND: The escalating prevalence of diabetes, with its multifaceted complications, poses a pressing challenge for healthcare systems globally. In response, the advent of continuous glucose monitoring (CGM) systems, offering technological solutions for daily diabetes management, presents significant opportunities. However, the widespread adoption faces several barriers, linked both to the technological configuration of the devices and to the psychological dimension of patients. Therefore, this study aims to apply and test a theoretical model that investigates the antecedents of the intention to use Continuous Glucose Monitoring systems. METHODS: The research model was built to unveil the impacts of psychological factors, functional components and rational constructs derived from the Technology Acceptance Model (TAM) on CGM systems sustained adoption. To ensure the comparability of results, we have collected data from people who had used Dexcom ONE Dexcom (San Diego, CA) for the first time for at least one month. Employing Structural Equation Modelling (SEM) techniques, the hypothesized relationships among constructs were assessed. RESULTS: The analyses confirmed the positive correlation of rational factors to the Intention to Use. Subjective Norm, intended as the physicians' influence, is positively correlated with the Perceived Usefulness. Trend Arrows, albeit being negatively correlated with Perceived Usefulness, have a positive correlation on Perceived Ease Of Use, reinforcing its mediating effect towards Perceived Usefulness. Among psychological factors, Trust in the CGM technology positively correlates with Intention to Use. Health Literacy is negatively correlated to the Intention to Use. CONCLUSIONS: These findings contribute to theoretical and managerial understanding, providing recommendations to enhance the adoption of CGM systems like Dexcom ONE.

What drives patients' acceptance of Digital Therapeutics? Establishing a new framework to measure the interplay between rational and institutional factors.

BACKGROUND: The rising incidence of chronic diseases among the population, further exacerbated by the phenomenon of aging, is a primary concern and a serious challenge for the healthcare systems worldwide. Among the wide realm of health digital technologies, the rise of Digital Therapeutics (DTx), which are medical devices able to deliver evidence-based treatments to manage and treat diseases, opens new opportunities. However, their diffusion and usage are still fragmented among countries. As the diffusion results from the adoption of technology from a social system and individual acceptance, this study aims to design and test a theoretical model that investigates the intention to use DTx, with a particular focus on the treatment of obesity, as a widespread and burdensome chronic condition. METHODS: This research is built on 336 answers coming from a survey to test the proposed model, which consists of a combination of organizational mechanisms, derived from Institutional Theory, and rational factors, derived from the Technology Acceptance Model (TAM). The survey has been delivered to patients and former patients of Istituto Auxologico Italiano, a hospital with several locations in northern Italy, recognized as a center of excellence for the treatment of obesity. RESULTS: The analyses of the answers, performed through the Structural Equation Modelling (SEM) technique, confirmed the influence of the Perceived Usefulness on Intention To Use, and of the Perceived Ease Of Use on the Perceived Usefulness, confirming the validity of the assumptions derived from the TAM. On the other hand, institutional factors were introduced as antecedents of the Perceived Usefulness, and the Perceived Ease Of Use. Results show that the Regulative Pillar influences both the TAM constructs, the Normative Pillar (peer influence) has a positive effect only on the Perceived Usefulness, and finally, the Cultural Pillar impacts the Perceived Ease Of Use. CONCLUSION: This study allows filling the knowledge gap regarding the usage of the Institutional as a means to predict individuals' intentions. Moreover, managerial contributions are available as the results have been operationalized into practical advice to managers and healthcare professionals to foster the adoption, and thus the diffusion, of Digital Therapeutics.

Comparison between real-world practice and application of the FRAX algorithm in the treatment of osteoporosis.

BACKGROUND AND AIMS: The most recent guidelines suggest treating patients whose FRAX 10-year fracture risk scores are ≥ 20%. However, this method of evaluation does not take into account parameters that are nonetheless relevant to the therapeutic choice. Our aim was to compare the therapeutic choices for treatment based on a wider assessment (real-world practice) with those based on FRAX scores, taking 20% as the cut-off score. METHODS: We obtained the medical history, bone mineral density (BMD) values, and the presence of major fragility fractures in a sample of 856 postmenopausal women. The 10-year FRAX risk of major osteoporotic fracture was calculated, and patients were grouped into risk classes ("FRAX < 20%" = low, "FRAX ≥ 20%" = high); we then compared the treated and untreated patients in each class. After an average interval of 2.5 years, changes in lumbar and femoral BMD and appearances of new fragility fractures were recorded. RESULTS: 83% of high-risk patients and 57% of low-risk patients were treated. The therapeutic decision was based mainly on densitometric values and the presence of vertebral fractures. At the 2.5 year follow-up, lumbar spine and femur BMD had decreased in the untreated group; 9.9% of the treated patients developed new vertebral fragility fractures, compared with 5.3% of the untreated patients. DISCUSSION AND CONCLUSIONS: Our wider assessment designated as at high fracture risk a group of patients who had not been identified by the FRAX assessment. FRAX could underestimate the risk of fracture in older people, for which the therapeutic choice should consider a broader approach, also based on individual patient's needs.

Dietary inflammatory index is associated with lung function in healthy older adults.

OBJECTIVES: Aging is associated with low-grade chronic inflammation contributing to a decline in lung performance. The Dietary Inflammatory Index (DII) has been introduced to evaluate the inflammatory potential of different diets, which may further affect individuals' respiratory function. This study investigates the association between DII and lung performance in older adults. METHODS: This cross-sectional study included 155 adults aged ≥65 y recruited at public gyms in Padua, Italy. Participants were assessed on medical history, biochemical parameters, body composition (through dual energy x-ray absorptiometry), anthropometry, and lung function (by spirometry). Based on individuals' dietary habits, we computed their DII and categorized participants in the lower DII (comprising those in the lowest DII tertile) or the higher DII (comprising those in the highest DII tertiles) groups. The association of DII with forced expiratory volume in the first second (FEV1) and forced vital capacity (FVC) was tested through multivariable linear regression analyses in the total sample and stratified by body mass index (<25 kg/m2 versus ≥25 kg/m2). RESULTS: The mean age of the sample was 71.2 y and 80% were women. Individuals in the higher DII group had FEV1 and FVC values reduced by 0.15 L (95% CI, -0.29 to -0.01 L) and 0.25 L (95% CI, -0.43 to -0.07 L), respectively, as compared with those in the lower DII group. Results seemed to be more marked among participants with excess weight conditions. CONCLUSIONS: Pro-inflammatory diets may affect lung function in fit older people, and this effect may be exacerbated in overweight or obese individuals.

Communicating Bad News to Older Patients from the Physician's Point of View: Focus on the Influence of Gender and Length of Work Experience.

BACKGROUND: Communicating bad news is of great interest in the geriatric field, but few works have considered the physician's point of view in this regard. OBJECTIVES: The aim of this study was to explore possible differences related to physicians' gender and work experience in how a terminal diagnosis is disclosed to older patients. METHODS: Study participants were 420 Italian physicians (277 M, 143 F) working in clinical medicine (58.2%), surgery (33.3%), or other medical departments (8.5%). They completed an anonymous multiple-choice questionnaire that investigated various issues associated with communicating bad news to terminally ill older patients. RESULTS: Men had more work experience than women (55.6% vs. 44.8% had worked for ≥23 years) and were more likely to work in surgery departments, while more women worked in clinical medicine. Most physicians declared that terminally ill older patients, if mentally competent, should always (14.4%) or generally (64.3%) be directly and openly informed of their condition. With no difference in gender, length of work experience, or specialty area, 36.9% of physicians thought that this was a human right and 18% that it would improve the patient's quality of life. Where older patients were alone, male physicians were more likely than female (30.2% vs. 8.9%) to always communicate bad news directly to them. More than 70% of physicians, especially those with longer work experience, declared that they always or often took enough time to inform the patient. Female physicians and those working in clinical medicine were more likely to need psychological help when deciding to break bad news, but only a smaller proportion declared to have received it. CONCLUSIONS: Gender and work experience may influence how physicians communicate with patients and how often they seek psychological support.

Association of body surface area with fat mass, free fat mass and total weight in healthy individuals, and implications for the dosage of cytotoxic drugs.

BACKGROUND & AIMS: In oncology, the dosage of anti-neoplastic drugs is generally adapted to the patient's body surface area (BSA). We investigated the potential differences between BSA and body weight (BW) in estimating the variability in body composition among individuals, especially older adults. MATERIALS AND METHODS: The study population included 322 community-dwelling individuals with different age and sex: 45 adult men (AM, age 18-65 years), 86 older men (OM, age >65 years), 54 adult women (AW, age 18-65 years), and 137 older women (OW, age >65 years). For each participant, we estimated the body composition with dual-energy X-ray absorptiometry, and we calculated the BSA using the DuBois and DuBois formula. The strength of relationships between fat free mass (FFM) and fat mass (FM) with BSA, BW, and BMI were expressed as correlation (r) and determination coefficients (R2). RESULTS: Most of the included sample was normal weight (45.7%) or overweight (41.9%). FFM demonstrated a stronger association with BSA than with BW or BMI in all age/sex groups, with r ranging from 0.831 to 0.924 (p < 0.001 for all) and R2 from 0.691 to 0.853. Conversely, BW and BMI were more strongly related to FM than BSA, especially in women. For such relationship, BW, in particular, showed r ranging from 0.793 to 0.924 (p < 0.001 for all). CONCLUSIONS: This study suggests that BSA may be more appropriately used to estimate FFM, compared with BW. Instead, alternative parameters should be considered to estimate FM in patients at risk for adverse effects of lipophilic drugs, especially in older age.

The Impact of Smoking on Bone Metabolism, Bone Mineral Density and Vertebral Fractures in Postmenopausal Women.

BACKGROUND: Smoking is recognized among the risk factors for osteoporosis, but only few studies have comprehensively explored its influence on bone metabolism and strength. We aimed to evaluate smoking effects on calcium-phosphate metabolism, bone mineral density (BMD) and fracture risk in postmenopausal women. METHODS: Our sample included 1067 postmenopausal women who arrived to our osteoporosis outpatient clinic. Anamnestic data, smoking habits (categorized as never, former, and current; and by smoking intensity and duration), biochemical parameters, lumbar/femoral BMD, and presence of vertebral fractures were recorded. In a subsample of 357 women, the changes in BMD after a 2-yr follow-up period were also assessed. RESULTS: Current smokers had shorter reproductive age, lower body mass index, and higher prevalence of heavy alcohol consumption than former/never smokers. They also had lower PTH values and weaker linear association between serum vitamin D and parathyroid hormone (current ß = -0.11[SE = 0.004]; former ß = -0.14[SE = 0.01]; never ß = -0.20[SE = 0.003]; p < 0.01 for all). Baseline BMD did not reflect differences based on smoking habits, duration or intensity. However, after 2 years, only current smokers significantly worsened in femural BMD. After adjustment for confounders, the chance of having sustained vertebral fractures at the first evaluation increased by 74% (95% confidence interval:1.07-2.83) in current compared with never smokers, especially among heavy smokers. CONCLUSIONS: Smoking may negatively affect bone by inhibiting vitamin D-parathyroid hormone axis, reducing estrogen exposure, promoting risky health behaviors, and accelerating bone loss, especially at the femur. No significant differences were observed in these outcomes among former smokers, suggesting that quitting smoking has beneficial effects on bone health.

Phase angle and metabolic equivalents as predictors of frailty transitions in advanced age.

OBJECTIVES: The aim of this prospective study was to investigate whether two cellular and metabolic health indices, phase angle (PhA) and metabolic equivalents (METs), can predict changes in frailty states in fit community-dwelling older people. METHODS: A sample of 118 individuals aged ≥65 years who attended a twice-weekly mild fitness program of aerobic and/or resistance exercises was enrolled in the study. At baseline and after three years, individuals underwent a clinical examination, biochemical determinations, bioelectrical impedance analysis, body composition assessment with dual energy X-ray absorptiometry, physical performance tests, and frailty and sarcopenia assessment. In 78 participants was executed indirect calorimetry, too. Based on frailty transitions during the follow-up between non-frailty, pre-frailty and frailty, participants were categorized as improved, stable (non-frail or pre-frail), and worsened or remaining frail. The chances to experience different frailty changes by baseline PhA and METs were explored through multinomial regression analysis and expressed as odds ratios (OR) and 95% Confidence intervals (95%CI). RESULTS: During the follow-up, 8 participants improved in frailty status, 84 were stable and 26 worsened or remained frail. For each one-unit increase in PhA, the odds of improving in frailty increased by 4.53 times (95%CI:1.18-17.46); while for each one-unit increase in METs, the odds of worsening in frailty decreased by 65% (95%CI:0.16-0.79). CONCLUSIONS: PhA and METs may be indirect measures of functional reserve, with lower values being potential biomarkers of evolving frailty.
