Insulin degludec/liraglutide (IDegLira) maintains glycaemic control and improves clinical outcomes, regardless of pre-trial insulin dose, in people with type 2 diabetes that is uncontrolled on basal insulin.

AIMS: To assess whether people with type 2 diabetes transferring from higher basal insulin doses (> 20 units) to a starting dose of 16 units of insulin degludec/liraglutide (IDegLira) benefit from IDegLira with/without transient loss of glycaemic control. METHODS: Post hoc analysis of DUAL V and VII assessed fasting self-measured blood glucose (SMBG) over weeks 1-8, changes in HbA1c, body weight and mean insulin dose over 26 weeks, and percentage of participants achieving HbA1c < 53 mmol/mol (7.0%) by end of trial in participants with type 2 diabetes uncontrolled with basal insulin. IDegLira was compared with continued up-titration of insulin glargine (IGlar U100) in DUAL V, or switching to basal-bolus therapy in DUAL VII (IGlar U100 and insulin aspart), across pre-trial insulin dose groups (20-29, 30-39 and 40-50 units/day). RESULTS: In all subgroups, participants treated with IDegLira experienced significant improvements in HbA1c by end of trial, which were greater than with IGlar U100 up-titration (estimated treatment difference -5.86, -6.59 and -6.91 mmol/mol for pre-trial insulin doses of 20-29, 30-39 and 40-50 units/day, respectively) and similar to basal-bolus therapy (estimated treatment difference -0.16, -1.0 and -0.01 mmol/mol for pre-trial insulin doses of 20-29, 30-39 and 40-50 units/day, respectively). Compared with IGlar U100 and basal-bolus therapy, IDegLira participants experienced weight loss vs. weight gain, lower rates of hypoglycaemia and a lower mean end of trial total daily insulin dose. In both trials, mean fasting SMBG decreased from weeks 1 to 8 across all subgroups, despite a temporary increase in mean fasting SMBG in the 40-50 units pre-trial insulin dose group during week 1 [mean increase (sd) +1.1 (2.0) mmol/l for DUAL V and +1.1 (2.1) mmol/l for DUAL VII], which reverted to baseline by week 4. CONCLUSIONS: Regardless of pre-trial insulin dose, IDegLira resulted in improved clinical outcomes, even in participants transferring from 40-50 units of basal insulin, despite a transient (< 4 weeks), clinically non-relevant, elevation in pre-breakfast SMBG.

Insulin degludec improves health-related quality of life (SF-36® ) compared with insulin glargine in people with Type 2 diabetes starting on basal insulin: a meta-analysis of phase 3a trials.

AIM: To compare the effect of insulin degludec and insulin glargine on health-related quality of life in patients with Type 2 diabetes starting on insulin therapy. METHODS: Patient-level data from three open-label, randomized, treat-to-target trials of 26 or 52 weeks' duration were pooled using a weighted analysis in conjunction with a fixed-effects model. Insulin-naive patients received either insulin degludec (n = 1290) or insulin glargine (n = 632) once daily, in combination with oral anti-diabetic drugs. Glycaemic control was assessed via HbA(1c) and fasting plasma glucose concentrations. Rates of hypoglycaemia, defined as plasma glucose < 3.1 mmol/l (< 56 mg/dl), were recorded. Health-related quality of life was evaluated using the 36-item Short Form (SF-36(®) ) version 2 questionnaire. Statistical analysis was performed using a generalized linear model with treatment, trial, anti-diabetic therapy at baseline, gender, region and age as explanatory variables. RESULTS: Insulin degludec was confirmed as non-inferior to insulin glargine based on HbA(1c) concentrations. In each trial comprising the meta-analysis, fasting plasma glucose and confirmed overall and nocturnal (00.01-05.59 h) hypoglycaemia were all numerically or significantly lower with insulin degludec vs. insulin glargine. At endpoint, the overall physical health component score was significantly higher (better) with insulin degludec vs. insulin glargine [+0.66 (95% CI 0.04-1.28)], largely attributable to a difference [+1.10 (95% CI 0.22-1.98)] in the bodily pain domain score. In the mental domains, vitality was significantly higher with insulin degludec vs. insulin glargine [+0.81 (95% CI 0.01-1.59)]. CONCLUSIONS: Compared with insulin glargine, insulin degludec leads to improvements in both mental and physical health status for patients with Type 2 diabetes initiating insulin therapy.

Once-daily initiation of basal insulin as add-on to metformin: a 26-week, randomized, treat-to-target trial comparing insulin detemir with insulin glargine in patients with type 2 diabetes.

AIMS: This study assessed the efficacy and safety of once-daily insulin initiation using insulin detemir (detemir) or insulin glargine (glargine) added to existing metformin in type 2 diabetes (T2D). METHODS: This 26-week, multinational, randomized, treat-to-target trial involved 457 insulin-naïve adults with T2D (HbA1c 7-9%). Detemir or glargine was added to current metformin therapy [any second oral antidiabetic drug (OAD) discontinued] and titrated to a target fasting plasma glucose (FPG) ≤90 mg/dl (≤5.0 mmol/l). Primary efficacy endpoint was change in HbA1c. RESULTS: Mean (s.d.) HbA1c decreased with detemir and glargine by 0.48 and 0.74%-points, respectively, to 7.48% (0.91%) and 7.13% (0.72%) [estimated between-treatment difference, 0.30 (95% CI: 0.14-0.46)]. Non-inferiority for detemir at the a priori level of 0.4%-points was not established. The proportions of patients reaching HbA1c ≤ 7% at 26 weeks were 38% and 53% (p = 0.026) with detemir and glargine, respectively. FPG decreased ∼43.2 mg/dl (∼2.4 mmol/l) in both groups [non-significant (NS)]. Treatment satisfaction was good for both insulins. Hypoglycaemia, which occurred infrequently, was observed less with detemir than glargine [rate ratio 0.73 (95% CI 0.54-0.98)]. The proportions of patients reaching HbA1c ≤ 7% without hypoglycaemia in the detemir and glargine groups were 32% and 38% (NS), respectively. Weight decreased with detemir [-0.49 (3.3) kg] and increased with glargine [+1.0 (3.1) kg] (95% CI for difference: -2.17 to -0.89 kg). CONCLUSION: While both detemir and glargine, when added to metformin therapy, improved glycaemic control, glargine resulted in greater reductions in HbA1c, while detemir demonstrated less weight gain and hypoglycaemia.

Insulin adherence behaviours and barriers in the multinational Global Attitudes of Patients and Physicians in Insulin Therapy study.

AIMS: To examine patient and physician beliefs regarding insulin therapy and the degree to which patients adhere to their insulin regimens. METHODS: Internet survey of 1250 physicians (600 specialists, 650 primary care physicians) who treat patients with diabetes and telephone survey of 1530 insulin-treated patients (180 with Type 1 diabetes, 1350 with Type 2 diabetes) in China, France, Japan, Germany, Spain, Turkey, the UK or the USA. RESULTS: One third (33.2%) of patients reported insulin omission/non-adherence at least 1 day in the last month, with an average of 3.3 days. Three quarters (72.5%) of physicians report that their typical patient does not take their insulin as prescribed, with a mean of 4.3 days per month of basal insulin omission/non-adherence and 5.7 days per month of prandial insulin omission/non-adherence. Patients and providers indicated the same five most common reasons for insulin omission/non-adherence: too busy; travelling; skipped meals; stress/emotional problems; public embarrassment. Physicians reported low patient success at initiating insulin in a timely fashion and adjusting insulin doses. Most physicians report that many insulin-treated patients do not have adequate glucose control (87.6%) and that they would treat more aggressively if not for concern about hypoglycaemia (75.5%). Although a majority of patients (and physicians) regard insulin treatment as restrictive, more patients see insulin treatment as having positive than negative impacts on their lives. CONCLUSIONS: Glucose control is inadequate among insulin-treated patients, in part attributable to insulin omission/non-adherence and lack of dose adjustment. There is a need for insulin regimens that are less restrictive and burdensome with lower risk of hypoglycaemia.

Improved health status with insulin degludec compared with insulin glargine in people with type 1 diabetes.

AIMS: The efficacy and safety of insulin degludec (degludec), a new-generation ultra-long-acting basal insulin, was compared with insulin glargine (glargine) in people with Type 1 diabetes mellitus in a 16-week, open-label, randomized trial. Health status, an important aspect of effective diabetes management, was also assessed. METHODS: Degludec (n = 59) or glargine (n = 59) were injected once daily, with insulin aspart at mealtimes. Health status assessment utilized the validated Short Form 36 Health Survey, version 2, which has two summary component scores for mental and physical well-being, each comprising four domains. RESULTS: At study end, HbA(1c) reductions were comparable between groups, but confirmed nocturnal hypoglycaemia was significantly less frequent with degludec [relative rate 0.42 (95% CI 0.25-0.69)], and overall hypoglycaemia numerically less frequent [relative rate 0.72 (95% CI 0.52-1.00)]. After 16 weeks, a significant improvement in Short Form 36 Health Survey mental component score of +3.01 (95% CI 0.32-5.70) was obtained for degludec against glargine, attributable to significant differences in the social functioning [+8.04 (95% CI 1.89-14.18)] and mental health domains [+2.46 (95% CI 0.10-4.82)]. For mental component score, Cohen's effect size was 0.42, indicating a small-to-medium clinically meaningful difference. The physical component score [+0.66 (95% CI -2.30 to 3.62)] and remaining domains were not significantly different between degludec and glargine. CONCLUSIONS: In the context of comparable overall glycaemic control with glargine, degludec improved mental well-being as measured using the mental component score of the Short Form 36 Health Survey. The improvements in overall mental component score and the underlying social functioning and mental health domains with degludec compared with glargine may relate to the observed reduction in hypoglycaemic events.

Factors associated with injection omission/non-adherence in the Global Attitudes of Patients and Physicians in Insulin Therapy study.

AIM: To examine factors associated with insulin injection omission/non-adherence on a global basis. METHODS: Telephone survey of 1530 insulin-treated adults with self-reported diabetes (110 type 1 and 1420 type 2) in China, France, Japan, Germany, Spain, Turkey, UK or USA. Participants had a mean age of ∼60 years, ∼15 years duration of diabetes and ∼9 years duration of insulin treatment. Regression analysis assessed the independent associations (p < 0.05) of country, participant characteristics and treatment-related beliefs/perceptions with number of days in the past month that an insulin injection was missed or not taken as prescribed. RESULTS: One third (35%) of respondents reported one or more days (mean: ∼3 days) of insulin omission/non-adherence. Insulin omission/non-adherence differed widely across countries (range = 20-44%); differences in days of insulin omission/non-adherence were maintained after adjustment for other risk factors. Most risk factors had similar relationships with insulin omission/non-adherence across countries (few interactions with country). Insulin omission/non-adherence was more frequent among respondents who were male, younger, had type 2 diabetes or more frequent hypoglycaemia, were less successful with other treatment tasks, regarded insulin adherence as less important, had more practical/logistical barriers and difficulties with insulin adherence, were concerned that insulin treatment required lifestyle changes or were dissatisfied with the flexibility of injection timing. CONCLUSIONS: The results of this large-scale study suggest that insulin omission/non-adherence is common and associated with several modifiable risk factors (including practical barriers, injection difficulties, lifestyle burden and regimen inflexibility). Additional efforts to address these risk factors might reduce the frequency of insulin omission/non-adherence and lead to improved clinical outcomes.

Study of Once Daily Levemir (SOLVE™): insights into the timing of insulin initiation in people with poorly controlled type 2 diabetes in routine clinical practice.

AIMS: The aim of this analysis is to determine the timing of insulin initiation in routine clinical practice, especially in relation to glycaemic control and use of oral antidiabetic drugs (OADs). METHODS: Study of Once Daily Levemir was a 24-week international observational study involving 10 countries which evaluated the safety and effectiveness of initiating once-daily insulin detemir in people with type 2 diabetes mellitus (T2DM) being treated with one or more OADs (clinical trial number NCT00825643 and NCT00740519). RESULTS: A total of 17 374 participants were enrolled in the study: aged 62 ± 12 years, 53% male, T2DM duration 10 ± 7 years, body mass index 29.3 ± 5.4 kg/m(2) . Pre-insulin HbA1c was 8.9 ± 1.6%. The proportion of patients with HbA1c ≥9.0% ranged from 64% (UK) to 23% (Poland). Pre-insulin OAD treatment included metformin (81%), sulphonylureas (59%), glinides (16%), thiazolidinediones (TZD) (12%), α-glucosidase inhibitors (12%) and dipeptidyl peptidase (DPP)-IV inhibitors (7%). The mean starting dose of insulin detemir for the total cohort was 0.16 ± 0.09 U/kg. Differences in OAD use and insulin doses at initiation were evident among participating countries. The largest proportional changes in OAD prescribing at insulin initiation were seen with glinides (+15%), sulphonylureas (-19%), TZD (-31%) and DPP-IV inhibitors (-28%). CONCLUSIONS: Despite well-documented benefits of timely glycaemic control and consensus guidelines encouraging earlier use of insulin, considerable clinical inertia exists with respect to initiating appropriate insulin therapy in people with T2DM. Considerable regional differences exist in the timing of insulin initiation and in the use of OADs.

The safety and efficacy of adding once-daily insulin detemir to oral hypoglycaemic agents in patients with type 2 diabetes in a clinical practice setting in 10 countries.

AIMS: Evaluate the safety and efficacy of once-daily insulin detemir initiated in routine clinical practice in patients with type 2 diabetes mellitus inadequately controlled with oral hypoglycaemic agents (OHAs). METHODS: This large observational study was conducted in 10 countries. Adverse event data (including hypoglycaemia) and glycaemic control were recorded before and 24 weeks following insulin initiation while patients continued routine clinical management. RESULTS: In this study, 17 374 patients (53% male) were included. Mean pre-insulin values (±s.d.) were: age 62 ± 12 years; body mass index (BMI) 29.3 ± 5.4 kg/m(2); diabetes duration 10 ± 7 years; haemoglobin A1c (HbA1c) 8.9 ± 1.6%. During the study, 27 patients experienced serious adverse drug reaction, severe hypoglycaemic events or both; and there were 31 episodes of severe hypoglycaemia in 21 patients. After 24 weeks, HbA1c was 7.5 ± 1.2% (change of -1.3%; p < 0.001) and mean weight change was -0.6 kg (confidence interval -0.7, -0.5 kg, p < 0.001). Daily insulin dose increased from 13 ± 6 U (0.16 ± 0.09 U/kg) to 22 ± 16 U (0.27 ± 0.17U/kg) by 24 weeks. Multivariate regression analysis identified several independent demographic and treatment predictors of end of study HbA1c. CONCLUSIONS: Addition of once-daily insulin detemir to patients with type 2 diabetes mellitus on OHA therapy resulted in few adverse events, significant improvements in glycaemic control, small reductions in weight and low rates of hypoglycaemia. On the basis of this study, concerns about hypoglycaemia or weight gain should not preclude initiation of basal insulin analogues in patients with poor glycaemic control on OHAs.

Impact of statins on the coagulation status of type 2 diabetes patients evaluated by a novel thrombin-generation assay.

PURPOSE: Dyslipidemia is common in type 2 diabetes (T2D) and contributes to cardiovascular disease (CVD) by exacerbating atherosclerosis and hypercoagulability. Statins can stabilize atherosclerotic plaque and reduce prothrombotic status. In the present study we aimed to evaluate the coagulation activity and the effect of statins on procoagulant state of T2D patients using a novel activated protein C (APC)-dependent thrombin-generation assay. METHODS: Procoagulant status (by HemosIL ThromboPath (ThP) assay) and in vivo platelet activation (by plasma soluble (s)CD40L levels) were analyzed in a retrospective, cross-sectional study of 198 patients with long-standing T2D and 198 controls. RESULTS: Procoagulant status of T2D patients was enhanced when compared to control subjects (p < 0.0001). Similarly, sCD40L levels were increased in T2D (p < 0.0001). When testing ThP as the dependent variable in a multivariate regression model, sCD40L (p < 0.0001) and statin treatment (p = 0.019) were independent predictors of the procoagulant state of T2D patients. Subgroup analysis showed a significant improvement of coagulability in T2D patients on statins (p = 0.012). CONCLUSIONS: The use of a standardized, easy-to-run, and commercially available APC-dependent thrombin-generation assay detected the presence of a procoagulant status in a large series of patients with long-standing T2D and demonstrated a significant impact of statins in the coagulation status of patients with T2D.

Demonstrating strategies for initiation of insulin therapy: matching the right insulin to the right patient.

AIMS: To increase awareness regarding the different types of insulin available and provide discussion regarding how each type of insulin can address the needs of diverse patients in terms of their unique requirements, preferences, medical history and lifestyle concerns. SUMMARY: New classes of antidiabetes medications, the development of insulin analogues and novel insulin delivery systems, provide more options for the management of type 2 diabetes. Given the inevitable progression of beta-cell dysfunction, along with the relatively limited glucose-lowering capacity of other agents, many patients will eventually require insulin for optimal glycaemic management. However, patients and physicians often fail to initiate insulin early enough during the progression of disease to maintain the recommended levels of glycaemic control. The inherent properties of the new insulin analogues, more physiological and user-friendly time-action profiles compared with older human insulin formulations, may partly address the barriers to insulin use. Insulin analogues include rapid acting (for prandial glycaemic control), long acting (for basal insulin coverage) and premixed insulin analogues, which combine both a rapid acting and an extended duration component in a single insulin formulation. Various case-based scenarios on initiating and intensifying therapy with insulin analogues will be presented. CONCLUSIONS: Development of an individualised treatment plan for initiation of insulin is a critical step in achieving target glycaemic levels in patients with type 2 diabetes.

Insulin detemir improves glycaemic control without weight gain in insulin-naïve patients with type 2 diabetes: subgroup analysis from the PREDICTIVE study.

OBJECTIVE: Predictable Results and Experience in Diabetes through Intensification and Control to Target: an International Variability Evaluation (PREDICTIVE) is a multi-national, open-label, prospective, observational study assessing the safety and efficacy of insulin detemir in clinical practice. This post hoc subanalysis evaluates insulin-naïve patients on oral antidiabetic drugs (OADs) who were initiated on insulin detemir as basal therapy (+/- OADs). METHODS: The European cohort of the PREDICTIVE study currently includes 20,531 patients (12,981 with type 2 diabetes) who were prescribed insulin detemir and followed up for 12, 26 or 52 weeks. Here, we report data from a subgroup of 2377 OAD-treated, insulin-naïve type 2 diabetes patients for a mean follow-up of 14.4 weeks. Patients were prescribed insulin detemir as basal therapy (+/- OADs) by their physician, as part of routine clinical care. Results were reported in comparison with baseline observations. RESULTS: One serious adverse drug reaction was reported, which was a major hypoglycaemic episode. Treatment with insulin detemir (+/- OADs) significantly reduced mean haemoglobin A(1c) (HbA(1c)) (-1.3%; p < 0.0001), fasting glucose (-3.7 mmol/l; p < 0.0001), and within-patient fasting glucose variability (-0.5 mmol/l; p < 0.0001). In the majority of patients (82%), these improvements in glycaemic control were achieved with once daily administration of insulin detemir. There was a small reduction in mean body weight (-0.7 kg; p < 0.0001), which was most apparent in patients with a higher body mass index (BMI) at baseline. A significant negative relationship between weight change and baseline BMI was observed (greater the BMI, greater the weight reduction). Multiple regression analysis showed that BMI and HbA(1c) at baseline, and change in HbA(1c), were all predictors for weight change (p < 0.0001 for all), with BMI being the strongest predictor. CONCLUSIONS: Patients with type 2 diabetes naïve to insulin can be effectively treated with once-daily insulin detemir (+/- OADs) to achieve improved glycaemic control with no adverse effect on weight and a low risk of hypoglycaemia. These short-term results are consistent with the findings of clinical trials.

An electronic case manager for diabetes control.

OBJECTIVE: To evaluate the usage and safety of an electronic case manager (ECM) system designed to facilitate the task of glycemic control. Sustained improvement in blood glucose control is the proven treatment outcome that will reduce or eliminate the long-term complications of diabetes. RESEARCH DESIGN AND METHODS: A customized microcomputer system served as the ECM. Located at the clinic, this voice-interactive system required the remote patient to need only a touch-tone telephone. Patients accessed the system to report daily self-measured glucose levels or hypoglycemic symptoms together with associated lifestyle events. System beta-testing was in an open-case series (n = 184) in an academic diabetes center with the goal of evaluating the ECM in terms of utilization, frequency of crises, and fiscal matters. RESULTS: Of the patients, 58% (n = 107) actively used the ECM for their daily diabetes care, accumulating 788 patient-months of follow-up. Over 45,000 telephone calls were received by the ECM during the start-up year. Each call was processed instantly and automatically. Patients benefited from having 24-h access to the ECM. Prevalence of diabetes-related crises (hyperglycemia > 400 mg/dl [22 mmol/l] or hypoglycemia < 50 mg/dl [2.8 mmol/l]) decreased approximately threefold (P < 0.05), with a concomitant statistically significant decrease in HbA1c of 0.8% at 6 months (n = 45, P = 0.024) and 0.9% at 12 months (n = 30, P = 0.044). The ECM provided 24-h on-line assistance in adjusting daily insulin and/or tablet therapy, automatic generation of standardized medical reports, electronic medical-legal documentation, as well as a marked reduction in the time spent on the phone with patients. Clinic visits in managing complex diabetes were reduced approximately twofold (P < 0.0001), and the effort spent by case managers was estimated. CONCLUSIONS: Patients with diabetes who accessed the ECM system received timely, cost-effective, and reliable medical intervention. This reduced the incidence of diabetic crises and the need for frequent clinic visits. The ECM empowers case managers to provide safer and superior diabetes care.

Eight years' experience with foreign-body aspiration in children: what is really important for a timely diagnosis?

BACKGROUND/PURPOSE: Aspiration of foreign bodies remains a major cause of morbidity and mortality in childhood. The aim of this study was to evaluate the predictive diagnostic value of clinical signs and symptoms, the history, and the radiology to perform early diagnosis and therapy. METHODS: From January 1990 to March 1998, 87 children were admitted to the Pediatric Surgery Department of Universita di Padova because of suspected foreign body aspiration. Sensitivity and specificity of the considered diagnostic tools were evaluated. RESULTS: Neither clinical signs and symptoms nor radiology have sufficient diagnostic sensitivity, and especially specificity, on which to rely for the diagnosis. Only the choking crisis, when present in the history, has good sensitivity and specificity (respectively, 96% and 76% in this series). CONCLUSIONS: A choking crisis in the child's history should alert physicians to the possibility of a foreign body aspiration. In the present series, complications always were related to the diagnostic delay.

[The EX-utero Intrapartum Technique (EXIT) procedure in Italy]. / Il parto ex-utero intrapartum technique (EXIT) in Italia.

Aim of the study was to present the first two Italian cases of C-section performed with the EXIT procedure (EX-utero Intrapartum Technique). Deliveries were performed at the Division of Obstetrics and Gynecology of the Hospital of Padua in cooperation with the Pediatric Surgery Department, both tertiary care centers. The first case was a twin with a huge neck mass (cystic hygroma) and the second a fetus with an oropharyngeal mass (epignathus). Airway patency could have been compromised at birth in both of them. EXIT procedure consists in securing the airway of the fetus partially delivered and still connected with the placenta. This technique leaves an intact feto-placental circulation and guarantees a normal fetal oxygenation while fetal airway patency is secured. Both the fetuses were successfully intubated and the C-section ended up in a short period of time without maternal and fetal complications. The EXIT technique, performed for the first time in 1989 and now in many centers abroad, can be considered a safe procedure as long as a multidisciplinary approach is carried out. The EXIT procedure is indicated whenever fetal airways can be compromised at birth, that is when oropharyngeal masses, laryngeal atresia, cystic hygroma and goiter are encountered during prenatal ultrasound.

Detection and confirmation of milk adulteration with cheese whey using proteomic-like sample preparation and liquid chromatography-electrospray-tandem mass spectrometry analysis.

Caseinomacropeptide (CMP) is a peptide released by chymosin in cheese production, remaining in whey. Thus, CMP can be used as a biomarker to fluid milk adulteration through whey addition. Commonly, CMP is analyzed by reversed phase (RP-HPLC) or size-exclusion chromatography (SEC). However, some psychrotropic microorganisms - specially Pseudomonas fluorescens - when present in storaged milk, can produce, by enzymatic pathway, a CMP-like peptide generally called pseudo-CMP. These two peptides differ from each other only by one amino acid. RP-HPLC and SEC methods are unable to distinguish these two peptides, which demand development of a confirmatory method with high selectivity. Considering the several degrees of glycosilation and phosphorylation sites in CMP, allied with possible genetic variation (CMP A and CMP B), analytical methods able to differentiate these peptides are extremely complex. In the present work, we developed a proteomic-like technique for separation and characterization of these peptides, using liquid chromatography coupled to mass spectrometry with electrospray ionization able to differentiate and subsequently quantify CMP and pseudo-CMP in milk samples in order to identify adulteration or contamination of these products. The method shows satisfactory precision (<11%) with a detection limit of 1.0 µg mL(-1) and quantification limit of 5.0 µg mL(-1). Specificity, matrix effects and applicability to real samples analysis were also performed and discussed.

Preoperative evaluation in infants and children: recommendations of the Italian Society of Pediatric and Neonatal Anesthesia and Intensive Care (SARNePI).

BACKGROUND: The preoperative assessment involves the process of evaluating the patient's clinical condition, which is intended to define the physical status classification, eligibility for anesthesia and the risks associated with it, thus providing elements to select the most appropriate and individualized anesthetic plan. The aim of this recommendation was provide a framework reference for the preoperative evaluation assessment of pediatric patients undergoing elective surgery or diagnostic/therapeutic procedures. METHODS: We obtained evidence concerning pediatric preoperative evaluation from a systematic search of the electronic databases MEDLINE and Embase between January 1998 and February 2012. We used the format developed by the Italian Center for Evaluation of the Effectiveness of Health Care's scoring system for assessing the level of evidence and strength of recommendations. RESULTS: We produce a set of consensus guidelines on the preoperative assessment and on the request for preoperative tests. A review of the existing literature supporting these recommendations is provided. In reaching consensus, emphasis was placed on the level of evidence, clinical relevance and the risk/benefit ratio. CONCLUSION: Preoperative evaluation is mandatory before any diagnostic or therapeutic procedure that requires the use of anesthesia or sedation. The systematic prescription of complementary tests in children should be abandoned, and replaced by a selective and rational prescription, based on the patient history and clinical examination performed during the preoperative evaluation.

The relationship between schizoaffective, schizophrenic and mood disorders in patients admitted at Mathari Psychiatric Hospital, Nairobi, Kenya.

OBJECTIVE: The prevalence of schizoaffective disorder (SAD) and the relationship between schizophrenia (SCZ), SAD and mood disorders (MD) in non-Western countries is unknown. To determine the prevalence of SAD and the relationship between SCZ, SAD and MD in relation to socio-demographic, clinical and therapeutic variables in 691 patients admitted at Mathari Psychiatric Hospital, Kenya. METHOD: A cross-sectional comparative study using both clinician and SCID-1 for DSM-IV diagnoses. RESULTS: Approximately twenty three percent (n=160) met DSM-IV criteria for SAD using SCID-1. There were significant differences between SCZ, SAD and MD regarding: affective and core symptoms of schizophrenia (with the exception of core symptoms of schizophrenia between SCZ and SAD); presence of past trauma; a past suicide attempt; and comorbidity with alcohol and drug abuse disorders. SAD and MD patients took significantly more mood stabilizers than SCZ patients. There were no significant differences between the three groups regarding socio-demographic variables, brief psychiatric rating scale scores, cognitive performance, anxiety and depressive symptoms, presence of obsessions, and usage of both antipsychotics and antidepressants. CONCLUSION: There is no distinct demarcation between the three disorders. This lends support to recent evidence suggesting that SAD might constitute a heterogeneous group composed of both SCZ and MD patients or a middle point of a continuum between SCZ and MD.

Incretin-based therapy in combination with basal insulin: a promising tactic for the treatment of type 2 diabetes.

Incretin therapies such as dipeptidyl peptidase-4 inhibitors (DPP-4Is) and GLP-1 receptor agonists (GLP-1RAs) have become well-established treatments for type 2 diabetes. Both drug classes reduce blood glucose through physiological pathways mediated by the GLP-1 receptor, resulting in glucose-dependent enhancement of residual insulin secretion and inhibition of glucagon secretion. In addition, the GLP-1RAs reduce gastrointestinal motility and appear to have appetite-suppressing actions and, so, are often able to produce clinically useful weight loss. The glucose-dependency of their glucagon-inhibiting and insulin-enhancing effects, together with their weight-sparing properties, make the incretin therapies a logical proposition for use in combination with exogenous basal insulin therapy. This combination offers the prospect of an additive or synergistic glucose-lowering effect without a greatly elevated risk of hypoglycaemia compared with insulin monotherapy, and any insulin-associated weight gain might also be mitigated. Furthermore, the incretin therapies can be combined with metformin, which is usually continued when basal insulin is introduced in type 2 diabetes. Although the combination of incretin and insulin therapy is currently not addressed in internationally recognized treatment guidelines, several clinical studies have assessed its use. The data, summarized in this review, are encouraging and show that glycaemic control is improved and weight gain is limited or reversed (especially with the combined use of GLP-1RAs and basal insulin), and that the use of an incretin therapy can also greatly reduce insulin dose requirements. The addition of basal insulin to established incretin therapy is straightforward, but insulin dose adjustment (though not discontinuation) is usually necessary if the sequence is reversed.

Weight beneficial treatments for type 2 diabetes.

CONTEXT: The close link between type 2 diabetes and excess body weight highlights the need to consider the weight effects of different treatment regimens. We examine the impact of "weight-friendly" type 2 diabetes pharmacotherapies and suggest treatment strategies that mitigate weight gain. EVIDENCE ACQUISITION: Evidence was identified via PubMed search by class and agent and in bibliographies of review articles, with final articles for inclusion selected by author consensus. EVIDENCE SYNTHESIS: Substantial evidence confirms the weight benefits of metformin and shows that, of the newer available agents, glucagon-like peptide-1 (GLP-1) agonists and amylin analogs promote weight loss. Dipeptidyl peptidase-4 (DPP-4) inhibitors and bile acid sequestrants are weight-neutral. Liraglutide and exenatide appear to have similar effects on weight; however, recent research suggests a potentially greater effect of liraglutide on glycemic control compared to exenatide, when used as a second-line therapy. Mounting evidence suggests that insulin detemir may provide the most favorable weight benefits of available insulins. CONCLUSIONS: Weight-beneficial agents should be considered in patients, particularly obese patients, who fail to reach glycemic targets on metformin therapy. We propose the following treatment choices based on potential weight benefit and blood glucose increment: long-acting GLP-1 agonists (liraglutide), DPP-4 inhibitors, bile acid sequestrants, amylin analogs, and basal insulin for patients with elevated fasting plasma glucose; and short-acting (exenatide) or long-acting GLP-1 agonists, amylin analogs, DPP-4 inhibitors, acarbose, and bile acid sequestrants for patients with elevated postprandial glucose. The weight-sparing effects of insulin detemir, notably in patients with high body mass index, should also be considered when initiating insulin therapy.

Once-daily insulin detemir in a cohort of insulin-naïve patients with type 2 diabetes: a sub-analysis from the PREDICTIVE study.

OBJECTIVE: PREDICTIVE is a large, observational study of the empirical use of insulin detemir in patients with type 1 or type 2 diabetes (T1DM/T2DM). This post hoc analysis evaluates insulin-naïve patients with T2DM uncontrolled on oral antidiabetic drugs (OADs) who were initiated and remained on once-daily insulin detemir for 12 weeks. RESEARCH DESIGN AND METHODS: This observational, multinational, multi-center, open-label prospective study evaluated the efficacy and safety of insulin detemir in 1653 insulin-naïve patients with T2DM (mean age 60.8 +/- 10.9 years, BMI 29.8 +/- 4.8 kg/m(2), and HbA(1C) 8.82 +/- 1.50%). Statistical comparisons were made between baseline and 12-week follow up data. Our study was subject to the usual limitations of observational studies. MAIN OUTCOME MEASURES: Endpoints were: incidence of serious adverse drug reactions, including number of hypoglycemic events (total, major, and nocturnal), glycemic parameters, and weight change. RESULTS: Following insulin initiation, no significant change occurred in the number of nocturnal hypoglycemic events or total hypoglycemic events (p = 0.4513), and no serious adverse drug reactions were observed during the 12 weeks of treatment. HbA(1C) decreased by a mean 1.25% (SD +/- 1.25%; p < 0.0001), with 30% of patients (n = 383) achieving HbA(1C) <7% at 12 weeks. Mean changes in fasting blood glucose and fasting blood glucose variability were -3.62 mmol/L (SD +/- 2.93; p < 0.0001) and -0.48 mmol/L (SD +/- 1.03; p < 0.0001), respectively. Body weight decreased by a mean 0.5 kg (SD +/- 3.3; p < 0.0001), with weight loss or no weight change occurring in a substantial percentage of patients in each BMI category (<25, 25-30, 30-35, and >35 kg/m(2)). Patients with higher baseline BMI lost the most weight, with the greatest weight loss (-1.20 kg) reported in those with BMI >35 kg/m(2). CONCLUSIONS: Empirical use of insulin detemir as an insulin initiation strategy can improve glycemic control with good tolerability, including a low risk of hypoglycemia and a weight benefit, in a majority of insulin-naïve patients uncontrolled on OADs.
