Correlates of calcaneal quantitative ultrasound parameters in patients with diabetes: the study on the assessment of determinants of muscle and bone strength abnormalities in diabetes
OBJECTIVE: Quantitative ultrasound (QUS) provides an estimate of bone mineral
density (BMD) and also evaluates bone quality, which has been related to
increased fracture risk in people with diabetes. This study aimed at assessing
the correlates of calcaneal QUS parameters in diabetic subjects encompassing
various degrees of micro and macrovascular complications and a wide-range of
peripheral nerve function.
METHODS: Four hundred consecutive diabetic patients were examined by QUS to
obtain values of broadband ultrasound attenuation (BUA), the speed of sound
(SOS), quantitative ultrasound index (QUI), and BMD.
RESULTS: Among surrogate measures of complications, sensory and motor nerve
amplitude and heart rate response to cough test and standing correlated with QUS
parameters at univariate analysis, together with age, body mass index (BMI),
waist circumference, lipid profile, and renal function. Multivariate analysis
revealed that BUA, SOS, QUI, and BMD were independently associated with age, male
gender, hemoglobin A1c, BMI (or fat, but not fat-free mass), and somatic and
autonomic nerve function parameters.
CONCLUSIONS: These data indicate that peripheral nerve dysfunction is associated
with worse QUS parameters, possibly contributing to increased fracture risk in
diabetes. The positive relation of QUS measures with adiposity needs further
investigation. This trial is registered with ClinicalTrials.gov (NCT01600924)

Patients’ preferences for nutrition-related health outcomes in liver disease : a preliminary study using an electronic questionnaire
Background: Patients with liver disease frequently have nutritional problems but intervening to improve these is challenging. Healthcare interventions that respond to patients’ needs are associated with better health outcomes but no studies investigating patients’ preferences for nutrition-related outcomes in liver disease have been published. The aim of this study was to identify nutrition-related health outcomes that are important to patients with liver disease. Methodology: An electronic questionnaire was devised and reviewed by patients and dietitians with relevant experience. It comprised Likert scale and open questions focussing on six domains considered pertinent to patients with liver disease. An invitation to participate was posted on the website of a national liver charity and sent to liver patient support groups. Results: Fifty-one patients participated (22 men / 29 women). Responses indicated a wide range of preferred nutrition-related outcomes with those identified as very important most frequently focussing on gaining knowledge about which foods to eat more or less of, and on understanding why nutrition is important in liver disease. Women tended to score outcomes as more important than men. Participants who considered themselves overweight scored outcomes on body size and shape as more important than those with other nutritional problems. Additional outcomes were identified and included increased knowledge of healthy eating, interactions between medication and food, and supplementation. Conclusions: The study identified a wide range of nutrition-related outcomes that were important to this small sample of patients with liver disease and these may be useful to guide the direction of future nutrition-related management.Peer reviewedFinal Accepted Versio
Impact of chronic diuretic treatment on glucose homeostasis
Background
The use of diuretics for hypertension has been associated with unfavorable changes in
cardiovascular risk factors, such as uric acid and glucose tolerance, though the findings in the
literature are contradictory.
Methods
This study investigated whether diuretic use is associated with markers of metabolic and
cardiovascular risk, such as insulin-resistance and uric acid, in a cohort of adults without
known diabetes and/or atherosclerotic cardiovascular disease. Nine hundred sixty-nine
randomly selected participants answered a questionnaire on clinical history and dietary
habits. Laboratory blood measurements were obtained in 507 participants.
Results
Previously undiagnosed type 2 diabetes was recognized in 4.2% of participants who were on
diuretics (n = 71), and in 2% of those who were not (n = 890; P = 0.53). Pre-diabetes was
diagnosed in 38% of patients who were on diuretics, and in 17.4% (P < 0.001) of those who
were not. Multivariate analysis showed that insulin-resistance (HOMA-IR) was associated
with the use of diuretics (P = 0.002) independent of other well-known predisposing factors,
such as diet, physical activity, body mass index, and waist circumference. The use of
diuretics was also independently associated with fasting plasma glucose concentrations (P =
0.001) and uric acid concentrations (P = 0.01).
Conclusions
The use of diuretics is associated with insulin-resistance and serum uric acid levels and may
contribute to abnormal glucose toleranc
Level and correlates of physical activity and sedentary behavior in patients with type 2 diabetes: a cross-sectional analysis of the italian diabetes and exercise study-2
OBJECTIVE:
Patients with type 2 diabetes usually show reduced physical activity (PA) and increased sedentary (SED)-time, though to a varying extent, especially for low-intensity PA (LPA), a major determinant of daily energy expenditure that is not accurately captured by questionnaires. This study assessed the level and correlates of PA and SED-time in patients from the Italian Diabetes and Exercise Study_2 (IDES_2).
METHODS:
Three-hundred physically inactive and sedentary patients with type 2 diabetes were enrolled in the IDES_2 to be randomized to an intervention group, receiving theoretical and practical exercise counseling, and a control group, receiving standard care. At baseline, LPA, moderate-to-vigorous-intensity PA (MVPA), and SED-time were measured by accelerometer. Physical fitness and cardiovascular risk factors and scores were also assessed.
RESULTS:
LPA was 3.93±1.35 hours∙day-1, MVPA was 12.4±4.6 min∙day-1, and SED-time was 11.6±1.2 hours∙day-1, with a large range of values (0.89-7.11 hours∙day-1, 0.6-21.0 min∙day-1, and 9.14-15.28 hours∙day-1, respectively). At bivariate analysis, LPA and MVPA correlated with better cardiovascular risk profile and fitness parameters, whereas the opposite was observed for SED-time. Likewise, values of LPA, MVPA, and SED-time falling in the best tertile were associated with optimal or acceptable levels of cardiovascular risk factors and scores. At multivariate analysis, age, female gender, HbA1c, BMI or waist circumference, and high-sensitivity C reactive protein (for LPA and SED-time only) were negatively associated with LPA and MPA and positively associated with SED-time in an independent manner.
CONCLUSIONS:
Physically inactive and sedentary patients with type 2 diabetes from the IDES_2 show a low level of PA, though values of LPA, MVPA, and SED-time vary largely. Furthermore, there is a strong correlation of these measures with glycemic control, adiposity and inflammation, thus suggesting that even small improvements in LPA, MVPA, and SED-time might be associated with significant improvement in cardiovascular risk profile
From Community Governance to Customer Service and Back Again: Re-Examining Pre-Web Models of Online Governance to Address Platforms’ Crisis of Legitimacy
As online platforms grow, they find themselves increasingly trying to balance two competing priorities: individual rights and public health. This has coincided with the professionalization of platforms’ trust and safety operations—what we call the “customer service” model of online governance. As professional trust and safety teams attempt to balance individual rights and public health, platforms face a crisis of legitimacy, with decisions in the name of individual rights or public health scrutinized and criticized as corrupt, arbitrary, and irresponsible by stakeholders of all stripes. We review early accounts of online governance to consider whether the customer service model has obscured a promising earlier model where members of the affected community were significant, if not always primary, decision-makers. This community governance approach has deep roots in the academic computing community and has re-emerged in spaces like Reddit and special purpose social networks and in novel platform initiatives such as the Oversight Board and Community Notes. We argue that community governance could address persistent challenges of online governance, particularly online platforms’ crisis of legitimacy. In addition, we think community governance may offer valuable training in democratic participation for users
HbA1c variability as an independent correlate of nephropathy, but not retinopathy, in patients with type 2 diabetes: The renal insufficiency and cardiovascular events (RIACE) Italian Multicenter Study
OBJECTIVE: To examine the association of hemoglobin (Hb) A1c variability with microvascular complications in the large cohort of subjects with type 2 diabetes from the Renal Insufficiency And Cardiovascular Events (RIACE) Italian Multicenter Study.
RESEARCH DESIGN AND METHODS: Serial (3-5) HbA1c values collected in a 2-year period before enrollment were available from 8,260 subjects from 9 centers (of 15,773 patients from 19 centers). HbA1c variability was measured as the intraindividual SD of 4.52 \ub1 0.76 values. Diabetic retinopathy (DR) was assessed by dilated funduscopy. Chronic kidney disease (CKD) was defined based on albuminuria, as measured by immunonephelometry or immunoturbidimetry, and estimated glomerular filtration rate (eGFR) was calculated from serum creatinine.
RESULTS: Median and interquartile range of average HbA1c (HbA1c-MEAN) and HbA1c-SD were 7.57% (6.86-8.38) and 0.46% (0.29-0.74), respectively. The highest prevalence of microalbuminuria, macroalbuminuria, reduced eGFR, albuminuric CKD phenotypes, and advanced DR was observed when both HbA1c parameters were above the median and the lowest when both were below the median. Logistic regression analyses showed that HbA1c-SD adds to HbA1c-MEAN as an independent correlate of microalbuminuria and stages 1-2 CKD and is an independent predictor of macroalbuminuria, reduced eGFR, and stages 3-5 albuminuric CKD, whereas HbA1c-MEAN is not. The opposite was found for DR, whereas neither HbA1c-MEAN nor HbA1c-SD affected nonalbuminuric CKD.
CONCLUSIONS: In patients with type 2 diabetes, HbA1c variability affects (albuminuric) CKD more than average HbA1c, whereas only the latter parameter affects DR, thus suggesting a variable effect of these measures on microvascular complications

Encumbered by vulnerability and temporality - the meanings of trigger situations when learning to live with diabetes
AIMS AND OBJECTIVES: The aim of the study was to illuminate the meanings of trigger situations experienced in everyday life when learning to live with diabetes.
BACKGROUND: Adults become active learners when faced with situations they do not know how to manage, triggering a need to understand something in a different way than before. Knowing more about experiential learning for persons living with diabetes is important for understanding how learning can be supported by health care.
DESIGN: A life-world approach with a phenomenological hermeneutical method, inspired by the philosophy of Paul Ricoeur.
METHODS: This method was used for interpreting transcriptions of interviews and consists of three stages: naïve understanding, structural analysis and a comprehensive understanding. Participants (n = 13), with either type I or type II diabetes, were interviewed on three different occasions over a three-year period after being diagnosed with diabetes.
RESULTS: When learning to live with diabetes, the meanings of trigger situations were described as 'the unpredictable body heightens insecurity with awareness of one's own dependability', 'losing control in unsustainable situations' and 'encumbered by vulnerability and temporality in earlier familiar situations'.
CONCLUSION: The meanings of trigger situations were to lose the smooth, unreflected way of managing an everyday life situation, interlaced with feelings of lost control of how to live with new insights of being vulnerable. Trigger situations meant an opportunity for learning, as well as being demanding, unplanned and with limited freedom of choice. Trigger situations presented life and body as unpredictable.
RELEVANCE TO CLINICAL PRACTICE: If healthcare professionals can identify the worries and questions raised in trigger situations, knowledge gaps can be identified and reflected on to stimulate learning
Archives, libraries and museums: containers often sick, sometimes seriously sick
As far as the feeling of quietness and peace that they often convey, archives, museums and libraries also hide dangers that you may not imagine, either for visitors or especially for the members of the staff. Indeed the poor microclimatic conditions – often the consequences of materials and construction or building technologies that appear definitely obsolete – often arouse suspicion and worry among the staff. Wrong Thermo hygrometric parameters, the presence of volatile organic elements, mineral fibers, biocides, radon gas, aerial dispersive molecules, are among others some of the chemical physical polluters of major influence that may contribute to giving life to the so-called Sick Building Syndrome. But such spaces also bear biological polluters that can provoke pathologies of various types and importance, among which the feared Illness of Legionnaire. The presence of electromagnetic fields, but above all wrong lighting and wrong ergonomic working positions represent some risk factors for members of staff and visitors
