Aims To compare treatment satisfaction among people with type 2 diabetes receiving dulaglutide 1.5 mg and dulaglutide 0.75 mg (a once-weekly, long-acting, glucagon-like peptide-1 receptor agonist) with those receiving either exenatide or placebo ( AWARD-1 study) or metformin ( AWARD-3 study) over 52 weeks. Methods The Diabetes Treatment Satisfaction Questionnaire status version ( DTSQs) and change version ( DTSQc) were used to evaluate total treatment satisfaction and perceived frequency of hyperglycaemia and hypoglycaemia. Results In the AWARD-1 study, significant improvements from baseline were observed in total DTSQs score for both dulaglutide doses (26 and 52 weeks) and exenatide (26 weeks). The improvement was significantly greater with both dulaglutide doses compared with placebo (26 weeks) and exenatide (26 and 52 weeks). The perceived frequency of hyperglycaemia was lower for all groups at 26 and 52 weeks compared with baseline. The improvement was greater with both dulaglutide doses and exenatide compared with placebo at 26 weeks, and was also greater with both dulaglutide doses compared with exenatide at 26 and 52 weeks. The exenatide group had an increase in perceived frequency of hypoglycaemia at 26 and 52 weeks. In the AWARD-3 study, significant improvements from baseline were observed for total DTSQs scores in all groups at 26 and 52 weeks. Perceived frequency of hyperglycaemia was lower for all groups at 26 and 52 weeks compared with baseline, and this improvement was greater with both dulaglutide doses compared with metformin at 52 weeks. Conclusions Dulaglutide was associated with improvements in treatment satisfaction and a decrease in perceived frequency of hyperglycaemia. [ABSTRACT FROM AUTHOR]

Diabet. Med. 27, 812–822 (2010) Aims For selected individuals with complex Type 1 diabetes, pancreatic islet transplantation (IT) offers the potential of excellent glycaemic control without significant hypoglycaemia, balanced by the need for ongoing systemic immunosuppression. Increasingly, patient-reported outcomes (PROs) are considered alongside biomedical outcomes as a measure of transplant success. PROs in IT have not previously been compared directly with the closest alternate treatment option, pancreas transplant alone (PTA) or pancreas after kidney (PAK). Methods We used a Population, Intervention, Comparisons, Outcomes (PICO) strategy to search Scopus and screened 314 references for inclusion. Results Twelve studies [including PRO assessment of PAK, PTA, islet-after kidney (IAK) and islet transplant alone (ITA); n = 7–205] used a total of nine specified and two unspecified PRO measures. Results were mixed but identified some benefits which remained apparent up to 36 months post-transplant, including improvements in fear of hypoglycaemia, as well as some aspects of diabetes-specific quality of life (QoL) and general health status. Negative outcomes included short-term pain associated with the procedure, immunosuppressant side effects and depressed mood associated with loss of graft function. Conclusions The mixed results may be attributable to limited sample sizes. Also, some PRO measures may lack sensitivity to detect actual changes, as they exclude issues and domains of life likely to be important for QoL post-transplantation and when patients may no longer perceive themselves to have diabetes. Thus, the full impact of islet/pancreas transplantation (alone or after kidney) on QoL is unknown. Furthermore, no studies have assessed patient satisfaction, which may highlight further advantages and disadvantages of transplantation. [ABSTRACT FROM AUTHOR]

Aims Quality of life (QoL) is recognized widely as an important health outcome in diabetes, where the burden of self-management places great demands on the individual. However, the concept of QoL remains ambiguous and poorly defined. The aim of our review is to clarify the measurement of QoL in terms of conceptualization, terminology and psychometric properties, to review the instruments that have been used most frequently to assess QoL in diabetes research and make recommendations for how to select measures appropriately. Methods A systematic literature search was conducted to identify the ten measures most frequently used to assess QoL in diabetes research (including clinical trials) from 1995 to March 2008. Results Six thousand and eight-five abstracts were identified and screened for instrument names. Of the ten instruments most frequently used to assess ‘QoL’, only three actually do so [i.e. the generic World Health Organization Quality of Life (WHOQOL) and the diabetes-specific Diabetes Quality of Life (DQOL) and Audit of Diabetes-Dependent Quality of Life (ADDQoL)]. Seven instruments more accurately measure health status [Short-Form 36 (SF-36), EuroQoL 5-Dimension (EQ-5D)], treatment satisfaction [Diabetes Treatment Satisfaction Questionnaire (DTSQ)] and psychological well-being [Beck Depression Inventory (BDI), Hospital Anxiety and Depression Scale (HADS), Well-Being Questionnaire (W-BQ), Problem Areas in Diabetes (PAID)]. Conclusions No single measure can suit every purpose or application but, when measures are selected inappropriately and data misinterpreted, any conclusions drawn are fundamentally flawed. If we value QoL as a therapeutic goal, we must ensure that the instruments we use are both valid and reliable. QoL assessment has the proven potential to identify ways in which treatments can be tailored to reduce the burden of diabetes. With careful consideration, appropriate measures can be selected and truly robust assessments undertaken successfully. [ABSTRACT FROM AUTHOR]

The article discusses the importance of measuring of diabetes on quality of life (QoL). It states that the use of hypothetical scenarios in the Audit of Diabetes Depended Quality of Life but in other patient-completed measures in conditions such as asthma. It mentions that for many people the importance weightings may make little difference to the ranking of scores but for others, the importance weighting will make a substantial difference.

- Abstract
Objectives/hypothesis: The 22-item Sinonasal Outcome Test (SNOT-22) is a validated chronic rhinosinusitis health-related quality-of-life outcome (HRQoL) measure; however, SNOT-22 domains have not been validated specifically for chronic rhinosinusitis with nasal polyps (CRSwNP)., Study Design: Validation of SNOT-22 domain structure, using data from 3 randomized, placebo-controlled, double-blinded, multicenter clinical trials of dupilumab in adults with moderate-to-severe CRSwNP., Methods: Preliminary dimensional structure was derived by exploratory factor analyses of SNOT-22 data from a phase 2 trial (NCT01920893) of dupilumab for the treatment of CRSwNP. Data from 2 phase 3 clinical trials (NCT02912468 and NCT02898454) were then used for confirmatory factor analysis, and evaluated for reliability, construct validity, and responsiveness. In all three trials, the SNOT-22 was administered electronically on a tablet and trial participants were required to answer all items., Results: Factor analysis supported five domains: Nasal, Ear/Facial, Sleep, Function, and Emotion. Correlations between domains were moderate to high, ranging from 0.53 (Nasal-Emotion) to 0.88 (Function-Sleep). Construct validity was mostly supported; relationships with other measures were almost always in the intended direction and magnitude. Internal consistency reliability also confirmed questionnaire structure with strong Cronbach's alpha values (all >0.80). Moderate-to-high correlations were observed between change in SNOT-22 domain scores and other study patient-reported outcome measures, along with large effect-size estimates (≥0.7), demonstrating responsiveness of the Nasal, Sleep, and Function domains. Emotion and Ear/Facial domains had small-to-moderate effect sizes., Conclusions: Psychometric analyses support the validity, reliability, and responsiveness of five domains of SNOT-22 (Nasal, Ear/Facial, Sleep, Function, and Emotion) for assessing symptoms and impact on HRQoL in patients with CRSwNP.

- Abstract
Background: We investigated the rate of severe hypoglycemic events and confounding factors in patients with type 2 diabetes treated with sulfonylurea at specialized diabetes centers, documented in the German/Austrian DPV-Wiss database., Methods: Data from 29 485 sulfonylurea-treated patients were analyzed (median[IQR] age 70.8[62.2-77.8] years, diabetes duration 8.2[4.3-12.8] years). The primary objective was to estimate the event rate of severe hypoglycemia (requiring external help, causing unconsciousness/coma/convulsion and/or emergency hospitalization). Secondary objectives included exploration of confounding risk factors through group comparison and Poisson regression., Results: Severe hypoglycemic events were reported in 826(2.8%) of all patients during their most recent year of sulfonylurea treatment. Of these, n = 531(1.8%) had coma, n = 501(1.7%) were hospitalized at least once. The adjusted event rate of severe hypoglycemia [95%CI] was 3.9[3.7-4.2] events/100 patient-years (coma: 1.9[1.8-2.1]; hospitalization: 1.6[1.5-1.8]). Adjusted event rates by diabetes treatment were 6.7 (sulfonylurea + insulin), 4.9 (sulfonylurea + insulin + other OAD), 3.1 (sulfonylurea + other OAD) and 3.8 (sulfonylurea only). Patients with ≥1 severe event were older (p < 0.001) and had longer diabetes duration (p = 0.020) than patients without severe events. Participation in educational diabetes-programs and indirect measures of insulin-resistance (increased BMI, plasma-triglycerides) were associated with fewer events (all p < 0.001). Impaired renal function was common (n = 3113 eGFR; ≤30 mL/min) and associated with an increased rate of severe events (≤30 mL/min: 7.7; 30-60 mL/min: 4.8; >60 mL/min: 3.9)., Conclusions: These real-life data showed a rate of severe hypoglycemia of 3.9/100 patient-years in sulfonylurea-treated patients from specialized diabetes centers. Higher risk was associated with known risk factors including lack of diabetes education, older age and decreased eGFR but also with lower BMI and lower triglyceride levels, suggesting that sulfonylurea treatment in those patients should be considered with caution., (Copyright © 2015 John Wiley & Sons, Ltd.)

- Abstract
The title compound, C(56)H(83)N(9)O(9)S·3CH(3)OH, is a methanol tris-olvate of the cyclo-linopeptide cyclo(Met(1)-Leu(2)-Ile(3)-Pro(4)-Pro(5)-Phe(6)-Phe(7)-Val(8)-Ile(9)) (henceforth referred to as CLP-B), which was isolated from flaxseed oil. All the amino acid residues are in an l-configuration based on the CORN rule. The cyclic nona-peptide exhibits eight trans peptide bonds and one cis peptide bond observed between the two proline residues. The conformation is stabilized by an α-turn and two consecutive β-turns each containing a N-H⋯O hydrogen bond between the carbonyl group O atom of the first residue and the amide group H atom of the fourth (α-turn) or the third residue (β-turns), repectively. In the crystal, the components of the structure are linked by N-H⋯O and O-H⋯O hydrogen bonds into chains parallel to the a axis.

- Abstract
The title compound, C(56)H(83)N(9)O(11)S·2C(4)H(10)O·H(2)O, is a butanol-water solvate of the cyclo-linopeptide cyclo(Metsulfone(1)-Leu(2)-Ile(3)-Pro(4)-Pro(5)-Phe(6)-Phe(7)-Val(8)-Ile(9)) (henceforth referred to as CLP-K) which was isolated from flax oil. All the amino acid residues are in an l configuration based on the CORN rule. The cyclic nona-peptide exhibits eight trans peptide bonds and one cis peptide bond observed between the two proline residues. The conformation is stabilized by an α- and a β-turn, each containing an N-H⋯O hydrogen bond between the carbonyl group O atom of the first residue and the amide group H atom of the fourth (α-turn) and the third residue (β-turn), repectively. In the crystal, the components of the structure are linked by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds into a two-dimensional network parallel to (001). The -C(H(2))OH group of one of the butanol solvent mol-ecules is disordered over two sets of sites with refined occupancies of 0.863 (4) and 0.137 (4).

- Abstract
The asymmetric unit of the title compound, [K(C(3)H(7)O(3))](n) or K[H(2)gl](n), common name potassium glycerolate, contains half the K(+) cation and half of the glycerolate anion. The other half of the anion is generated through a mirror plane passing through the K atom, and a C, an H and an O atom of the glycerolate ligand. The K(+) ion is coordinated by the O atoms of the OH groups, leading to a six-membered chelate ring that adopts a very distorted boat conformation. The negatively charged O atom of the glycerolate anion, [H(2)gl(-)], is found in the flagpole position and forms an ionic bond with the K(+) ion. The O atoms of the hydroxo groups are coordinated to two K(+) ions, whereas the negatively charged O atom is bonded to one K(+) ion. The K(+) ion is coordinated by three other symmetry-related monodentate H(2)gl(-) ligands, so that each H(2)gl(-) ligand is bonded to two K(+) ions, and the potassium has a seven-coordinate environment. The H(2)gl(-) ligands are connected via a strong O-H⋯O hydrogen bond and, together with the K⋯O inter-connections, form polymeric sheets which propagate in the directions of the a and b axes.

- Abstract
The Na(+) cation in the title compound, [Na(C(3)H(7)O(3))](n) or Na[H(2)gl], is coordinated by five O atoms leading to a distorted trigonal-bipyramidal geometry. The negatively charged O atom of the glycerolate anion is in an equatorial position, and the O atom of the hydroxo group, attached to the secondary C atom, occupies an axial position completing a five-membered non-planar chelate ring; this defines the asymmetric unit. The Na(+) cation is coordinated by three other symmetry-related monodentate H(2)gl(-) ligands, so that each H(2)gl(-) ligand is bonded to four Na(+) ions. The H(2)gl(-) ligands are connected via strong O-H⋯O hydrogen bonds and these, together with the Na⋯O inter-connections, are responsible for the formation of polymeric sheets which propagate in the directions of the b and c axes.
