Ultrarapid Insulin Use Can Reduce Postprandial Hyperglycemia and Late Hypoglycemia, Even in Delayed Insulin Injections: A Connected Insulin Cap-Based Real-World Study.

Objectives: Reaching optimal postprandial glucose dynamics is a daily challenge for people with type 1 diabetes (T1D). This study aimed to analyze the postprandial hyperglycemic excursion (PHEs) and late postprandial hypoglycemia (LPH) risk according to prandial insulin time and type. Research Design and Methods: Real-world, retrospective study in T1D using multiple daily injections (MDI) analyzing 5 h of paired continuous glucose monitoring and insulin injections data collected from the connected cap Insulclock®. Meal events were identified using the rate of change detection methodology. Postprandial glucometrics and LPH (glucose <70 mg/dL 2-5 h after a meal) were evaluated according to insulin injection time and rapid (RI) or ultrarapid analog, Fiasp® (URI), use. Results: Meal glycemic excursions (n = 2488), RI: 1211, 48.7%; UR: 1277, 51.3%, in 82 people were analyzed according to injection time around the PHE: -45 to -15 min; -15 to 0 min; and 0 to +45 min. In 63% of the meals, insulin was injected after the PHE started. Lower PHE was observed with URI versus RI (glucose peak-baseline; mg/dL; mean ± standard deviation): 106.7 ± 35.2 versus 111.2 ± 40.3 (P = 0.003), particularly in 0/+45 injections: 111.6 ± 40.2 versus 118.1 ± 43.3; (P = 0.002). One third (29.1%) of participants added a second (correction) injection. The use of URI and avoiding a second injection were independently associated with less LPH risk, even in delayed injections (0/+45), (-36%, odds ratio [OR] 0.641; confidence interval [CI]: 0.462-0.909; P = 0.012) and -56% (OR 0.641; CI: 0.462-0.909 P = 0.038), respectively. Conclusions: URI analog use as prandial insulin reduces postprandial hyper- and hypoglycemia, even in delayed injections.

Peritoneal Dialysis Exit-Site Care Protocols in Portugal and Its Association with Catheter-Related Infections.

INTRODUCTION: Exit-site infection (ESi) prevention is a key factor in lowering the risk of peritonitis. This study aimed to evaluate the associations between exit-site (ES) care protocols and the annual incidence rates of ESi and peritonitis in Portugal. METHODS: We performed a national survey using two questionnaires: one about the incidence of catheter-related infections and the other characterizing patients' education and ES care protocols. RESULTS: In 2017 and 2018, 14 Portuguese units followed 764 and 689 patients. ESi incidence rate was 0.41 episodes/year, and the peritonitis incidence rate was 0.37. All units monitor catheter-related infections on a yearly basis, use antibiotic prophylaxis at the time of catheter placement, and treat nasal carriage of S. aureus, although with different approaches. Screening for nasal carriage of S. aureus is performed by 12 units, and daily topical antibiotic cream is recommended by 6 out of 14 of the units. We did not find statistical differences in ESi/peritonitis, comparing these practices. The rate of ESis was lower with nonocclusive dressing immediately after catheter insertion, bathing without ES dressing, with the use of colostomy bags in beach baths and was higher with the use of bath sponge. The peritonitis rate was lower with bathing without ES dressing and if shaving of the external cuff was performed in the presence of chronic ESi. CONCLUSIONS: We found potential proceedings associated with ESi and peritonitis. A regular national audit of peritoneal dialysis units is an important tool for clarifying the best procedures for reduction of catheter-related infections.

Caloric adequacy of parenteral nutrition and its influence on the clinical outcome of hospitalised patients.

Background: The adaptation of Parenteral Nutrition (PN) to actual energy requirements of hospitalised patients is essential, since excessive and insufficient nutritional intake have been associated with poor clinical outcomes. Aim: To evaluate the adaptation of prescribed PN to the estimated nutritional requirements using three predictive equations and the influence of excessive/insufficient nutrient intake on patient clinical outcomes (nutritional parameters, metabolic and infectious complications). Methods: Prospective, observational study in hospitalised patients nutritionally assessed. Data was collected the first and fifth/sixth day of PN with clinical (infection, length of hospital stay), biochemical (visceral proteins, cholesterol, glucose, triglycerides, lymphocytes, CRP) and anthropometric parameters (skin folds, height, weight). Theoretical requirements were calculated using Harris-Benedict (HB), Mifflin-St Jeor (MF) and 25 Kcal/Kg/day formulas. The HB formula was used to compare estimated and provided requirements. Results: A total of 94 patients (mean: 72 ± 13.7 years old) were included with initial mean weight and height of 69.2 Kg and 162.8 cm, respectively (mean BMI: 26.1 Kg/m2). No statistically significant differences were found between the actual (1620 Kcal/day) and estimated caloric mean calculated with HB (1643 Kcal/day) and MF (1628 Kcal/day). When comparing with the caloric estimation, 31.9% of patients were underfed, while 14.9% were overfed. Intergroup analysis demonstrated significant variations in albumin, prealbumin, glucose, cholesterol, triglycerides and MUAC, with a significant increase of hyperglycaemia (+37.86; p < 0.05) and hypertriglyceridemia (+63.10; p < 0.05), being higher in overfed patients. Conclusion: In our study, inadequate nutrient intake was associated with a higher degree of hyperglycaemia and hypertriglyceridemia, without positive impact on anthropometric parameters.

Efficacy of a Connected Insulin Pen Cap in People With Noncontrolled Type 1 Diabetes: A Multicenter Randomized Clinical Trial.

OBJECTIVE: To assess the efficacy of the insulin pen cap Insulclock on improving glycemic control, treatment adherence, and user satisfaction in people with type 1 diabetes. RESEARCH DESIGN AND METHODS: This multicenter, open-label, randomized controlled trial comprised a 4-week run-in phase and a 6-week double-arm phase in which participants were randomly assigned into an active or masked mode. RESULTS: Fifty-five participants were evaluable (active group, n = 26, masked group, n = 29). The increase in time in range was higher in the active versus masked group (5.2% vs. -0.8%; P = 0.016). The active group showed a higher reduction in mean glucose, glucose management indicator, time above range, and high blood glucose index. On-time insulin doses increased in the active group and decreased in the masked group. CONCLUSIONS: Insulclock system use was associated with improved glycemic control, glycemic variability, hyperglycemia risk, and treatment adherence in people with uncontrolled type 1 diabetes.

Clinical Research on Type 2 Diabetes: A Promising and Multifaceted Landscape.

Type 2 diabetes constitutes an imposing epidemiological, economic, and scientific global challenge [...].

Usefulness of circulating EPAC1 as biomarkers of therapeutic response to GLP-1 receptor agonists.

AIMS: The response to Glucagon-like peptide-1 receptor agonists (GLP-1RAs) is highly varia-ble among patients. Thus, the identification of predictive biomarkers of therapeutic response to GLP-1 RA could help us to optimize the use of this class of drugs. GLP-1RAs increase exchange proteins directly activated by cAMP (EPAC). The aim of the present study was to assess whether the increase of EPAC1 after GLP-1RAs treatment could be a biomarker of clinical response. METHODS: After showing that GLP-1 (10 ng/mL) significantly increased the expression of EPAC1 in human endo-thelial vascular cells (HUVEC), a pilot clinical study was planned. For this purpose 49 patients with type 2 diabetes who started treatment with liraglutide were included. EPAC1 concentration was determined by ELISA before and at one month of liraglutide treatment. RESULTS: We found that serum concentration of EPAC1 increased significantly after treatment with liraglutide. Only in those patients in whom EPAC1 increased (64%), a significant decrease in HbA1c, LDL-C, body mass index (BMI), and waist circumference was shown. CONCLUSIONS: This pilot study suggests that the increase of circulating EPAC1 after GLP-1RAs treatment could be a useful biomarker to predict clinical GLP1-RAs response.

Pregnancy in a woman undergoing peritoneal dialysis: Management and dialysis options.

Pregnancy in patients with end-stage renal disease on maintenance dialysis is uncommon, with annual incidences reported at 0.3 - 2.7%. Peritoneal dialysis usage in pregnancy has been less reported than hemodialysis, although outcomes are similar. Nowadays, there are insufficient data to establish a generalizable dialysis strategy in pregnant women with end-stage renal disease. As such, decisions should be individualized, depending on clinical factors, residual renal function, and, whenever possible, choice of the patient. We report the case of a 22-year-old patient receiving peritoneal dialysis who delivered a full-term, normal weight, healthy baby with increased dialysis dose achieved by supplementary hemodialysis during pregnancy, thus enabling peritoneal dialysis to be continued until the third trimester and minimizing hemodialysis requirements.

Acute pericarditis after COVID 19 in a peritoneal dialysis patient.

COVID-19 is known to affect numerous organs which have ACE-2 receptors, lung being the most involved organ. Nevertheless, cardiac involvement is not uncommon and can occur through a variety of manifestations. The authors hereby report a case of pericarditis following SARS-CoV-2 infection. A 54-year-old man with end stage kidney disease under peritoneal dialysis presented with acute chest pain approximately 1 month after being diagnosed with COVID-19. Electrocardiogram revealed widespread ST segment elevation. The diagnosis of acute pericarditis secondary to the viral infection was made and the patient was treated accordingly. Etiology of acute pericarditis can be very varied, and, in many times, no cause is ascertained. In such circumstances, viral or immune mediated etiologies are assumed. In our case, since no cause was proven, pericarditis was assumed as secondary to the SARS-CoV-2 infection. This entity is probably underdiagnosed. In patients undergoing dialysis, uremic pericarditis is commonly the etiology. However, different causes must be taken into consideration, COVID-19 being one of them.

AlergiaPT: A Portuguese media campaign to inspire people with allergies to make a positive change in their life.

Allergic diseases comprise a significant cause of morbidity worldwide and a substantial burden on the health and medical systems of both developed and emerging economies. Although highly prevalent, relatively severe, and largely impactful on the quality of life of patients, allergic diseases are commonly trivialized. Increasing awareness of the relevance of allergic diseases as a major public health problem might lead to an improved acknowledgment by governments and health authorities. Based on the positive impact that media campaigns might have on health-related behaviors, as well as the large use of social media by different types of users, social media might be used as a powerful tool for spreading awareness and education even more effective than traditional face-to-face communication. Therefore, we aimed to develop a social media-based communication program, the AlergiaPT, reaching all stakeholders, to increase the awareness of allergic diseases tackling the causes, prevention, control, and economic impact. The AlergiaPT will provide user-generated and interactive content toward engagement, include both long-form and short-form video productions toward education, as well as stories and time-sensitive content toward empowerment. It will be targeted to all populations, engaging different stakeholders. Contents will address the 5 campaign goals: i) allergy health is promoted; ii) tolerance is actively reinforced, and avoidance reduced; iii) treatment control and guided self-management of patients of asthma, rhinitis, food allergy, and atopic eczema are strengthened; iv) recognition and treatment of severe allergy and anaphylaxis are improved, and v) indoor air quality is promoted. Engagement on the campaign will be promoted through stepwise educational takeaways meetings using different social media, and targeting all audience groups, by promoting the organization of resources for common goals and the involvement of social media to improve public awareness. The impact of AlergiaPT will be assessed through google analytics.

Changes in marine turbot (Scophthalmus maximus) epidermis and skin mucus composition during development from bilateral larvae to juvenile flat fish.

Alike other flat fish, marine turbot has the particularity that changes from larvae with bilateral symmetry to adult with asymmetry, in terms of the position of the eyes. As expected, the skin configuration of this species is also affected by the development and transformation suffered by fish during metamorphosis. In this context, changes in the epidermis of marine turbot were studied using conventional staining and histochemical techniques using six lectins (UEA-I, PNA, RCA-I, WGA, Con A and SBA). During development from larvae to juvenile (3-300 days post-hatching), the epidermis increased in both thickness and the number of cell layers. In fact, the simple cuboidal epithelium observed in larvae at day 3 already became stratified at days 10-12, which sequentially increase in thickness with fish development. Turbot epidermis is composed basically of four cell types: epithelial and mucous or secretory cells that are present through the development, and pigmented cells and a type that the authors described as club-like cells that appear during and post-metamorphosis. The Alcian blue-periodic acid Schiff (AB-PAS) histochemical method revealed the presence of neutral glycoconjugates in mucous and club-like cells at post-metamorphic stages of fish. Accordingly, lectin analysis showed mucous cells containing glycoproteins rich in fucose (UEA-I labelling) and glycoconjugates rich in the sequence galactose-N-acetyl galactosamine (PNA and RCA-I labelling) when this cell type appears. Interestingly, melanophores were observed in the dorsal epidermis of post-metamorphic juveniles. This type of cell contains a black-to-brown pigment that provides the skin the typical colour of this fish species. Changes in mucous coat composition were observed during fish development, which was attributed to different roles of the glycoconjugates.

Nível de conhecimento dos odontopediatras e endodontistas de Ilhéus-BA quanto ao procedimento de revascularização pulpar / Level of knowledge of pediatric dentists and endodontists of Ilheus-BA regarding the pulp revascularization procedure

Dentes necrosados com rizogêneze incompleta representam um desafio para os endodontistas e odontopediatras, visto que as paredes radiculares desses dentes são mais finas, o que as tornam mais susceptíveis a fraturas. Durante muitos anos a técnica preconizada foi a apicificação que ainda é bastante utilizada. Nesta técnica são realizadas trocas constantes de medicação intracanal. O dente continua fragilizado e existe o risco do paciente não concluir o tratamento já que tal técnica demanda várias sessões clínicas. Com os avanços da ciência, surge a revascularização pulpar, trazendo vários beneficíos, entre os quais estão a continuidade apical e o ganho de espessura das paredes, além do benefício de conclusão do tratamento em uma ou duas sessões. Entretanto é necessária sua proservação que leva em média dois anos. O objetivo desta pesquisa foi avaliar o nível de conhecimento dos odontopediatras e endodontistas do município de Ilhéus-Bahia, frente a casos de necrose pulpar de dentes com formação radicular incompleta. O método e forma de análise de dados foram de um estudo observacional, transversal, realizado em consultórios do município de Ilhéus-BA que foram selecionados por amostragem aleatória. Os dados foram coletados por meio de um questionário contendo 10 questões de múltipla escolha sobre revascularização pulpar, especialização do profissional e tempo de formação. 20 profissionais aceitaram participar da pesquisa. Desses, 10% não sabiam ou nunca tinham ouvido falar sobre a revascularização pulpar. Conclui-se que ainda existem especialistas no Município de Ilhéus-BA que apresentam conhecimento insuficiente sobre a terapia endodôntica regenerativa, sendo que os mesmos deveriam ter conhecimento desta técnica já que são os profissionais que prestam o atendimento ao paciente jovem com dentes necrosados, reforçando a necessidade de elaboração de estratégia de conscientização e educação de saúde para habilitação e atualização dos mesmos(AU)

Necrotic teeth with incomplete rizogenesis representa challenge for endodontists and pediatric dentists, since the root walls of these teeth are thinner, which makes them more susceptible to fractures. For many years the recommended technique was apexification, which is still widely used. In this technique, constant changes of intracanal medication are performed. The tooth remains fragile and there is a risk that the patient will not complete the treatment as this technique requires several clinical sessions. With advances in science, pulp revascularization appears, bringing several benefits, among which are the apical continuity and the gain in thickness of the walls, in addition to the benefit of completing the treatment in one or two sessions. However, its preservation is necessary, which takes on average two years. The objective of this research was to evaluate the level of knowledge of pediatric dentists and endodontists in the municipality of Ilhéus-Bahia, in the face of cases of pulp necrosis of teeth with incomplete root formation. The method and form of data analysis were from an observational, cross-sectional study, carried out in offices in the municipality of Ilheus-BA that were selected by random sampling. Data were collected through a questionnaire containing 10 multiple-choice questions about pulp revascularization, professional specialization and training time. 20 professionals agreed to participate in the research. Of these, 10% did not know or had never heard of pulp revascularization. It is concluded that there are still specialists in the municipality of Ilhéus-BA who have insufficient knowledge about regenerative endodontic therapy, and they should have knowledge of this technique since they are the professionals who provide care to young patients with necrotic teeth, reinforcing the need to develop a health awareness and education strategy to enable and update them(AU)

DNA-based detection of Mycobacterium avium subsp. paratuberculosis in domestic and municipal water from Porto (Portugal), an area of high IBD prevalence.

Mycobacterium avium subsp. paratuberculosis (MAP) may play a role in the pathology of human inflammatory bowel disease (IBD). Previously, we found a high frequency (98% in patients with active disease) of MAP DNA detection in the blood of Portuguese Crohn's Disease patients, suggesting this cohort has high exposure to MAP organisms. Water is an important route for MAP dissemination, in this study we therefore aimed to assess MAP contamination within water sources in Porto area (the residential area of our IBD study cohort). Water and biofilms were collected in a wide variety of locations within the Porto area, including taps connected to domestic water sources and from municipal water distribution systems. Baseline samples were collected in early autumn plus further domestic water samples in early winter, to assess the effect of winter rainfall. DNA was extracted from all 131 samples and IS900-based nested PCR used to assess the frequency of MAP presence. Our results show high MAP positivity in municipal water sources (20.7% of water samples and 41.4% of biofilm samples) and even higher amongst domestic sources (30.8% of water samples and 50% of biofilm samples). MAP positivity in biofilms correlated with positivity in water samples from the same sources. A significantly higher frequency of MAP-positivity was observed during winter rains as compared with samples collected in autumn prior to the winter rainfall period (61.9% versus 30.8%). We conclude that domestic and municipal water sources of Porto region have a high burden of MAP contamination and this prevalence increases with rainfall. We hypothesize that human exposure to MAP from local water supplies is commonplace and represents a major route for MAP transmission and challenge which, if positively linked to disease pathology, may contribute to the observed high prevalence of IBD in Porto district.

Geographical clustering and socioeconomic factors associated with hypoglycemic events requiring emergency assistance in Andalusia (Spain).

INTRODUCTION: The geographical distribution of hypoglycemic events requiring emergency assistance was explored in Andalusia (Spain), and potentially associated societal factors were determined. RESEARCH DESIGN AND METHODS: This was a database analysis of hypoglycemia requiring prehospital emergency assistance from the Public Company for Health Emergencies (Empresa Pública de Emergencias Sanitarias (EPES)) in Andalusia during 2012, which served 8 393 159 people. Databases of the National Statistics Institute, Basic Spatial Data of Andalusia and System of Multiterritorial Information of Andalusia were used to retrieve spatial data and population characteristics. Geographic Information System software (QGIS and GeoDA) was used for analysis and linkage across databases. Spatial analyses of geographical location influence in hypoglycemic events were assessed using Moran's I statistics, and linear regressions were used to determine their association with population characteristics. RESULTS: The EPES attended 1 137 738 calls requesting medical assistance, with a mean hypoglycemia incidence of 95.0±61.6 cases per 100 000 inhabitants. There were significant differences in hypoglycemia incidence between basic healthcare zones attributable to their geographical location in the overall population (Moran's I index 0.122, z-score 7.870, p=0.001), women (Moran's I index 0.088, z-score 6.285, p=0.001), men (Moran's I index 0.076, z-score 4.914, p=0.001) and aged >64 years (Moran's I index 0.147, z-score 9.753, p=0.001). Hypoglycemia incidence was higher within unemployed individuals (ß=0.003, p=0.001) and unemployed women (ß=0.005, p=0.001), while lower within individuals aged <16 years (ß=-0.004, p=0.040), higher academic level (secondary studies) (ß=-0.003, p=0.004) and women with secondary studies (ß=-0.005, p<0.001). In subjects aged >64 years, lower rate of hypoglycemia was associated with more single-person homes (ß=-0.008, p=0.022) and sports facilities (ß=-0.342, p=0.012). CONCLUSIONS: This analysis supports the geographical distribution of hypoglycemia in the overall population, both genders and subjects aged >64 years, which was affected by societal factors such as unemployment, literacy/education, housing and sports facilities. These data can be useful to design specific prevention programs.

Efficacy of Insulclock in Patients with Poorly Controlled Type 1 Diabetes Mellitus: A Pilot, Randomized Clinical Trial.

Insulclock® is an electronic device designed to improve treatment adherence and insulin injection tracking. This randomized, single-center, pilot study assessed the clinical impact of Insulclock on glycemic control and variability, treatment adherence, and satisfaction in patients with uncontrolled type 1 diabetes mellitus (T1DM). We also compared these outcomes between the Active and Masked groups (with or without receiving reminders and app alerts). Sixteen patients completed the study: 10 in the Active group and 6 in the Masked group. Insulclock use was associated with a decrease in mean glucose (-27.0 mg/dL [1.5 mmol/L]; P = 0.013), glucose standard deviation (-14.4 mg/dL [0.8 mmol/L]; P = 0.003), and time above range (-12.5%; P = 0.0026), and an increase in time in range (TIR) (+7%; P = 0.038) in the overall population. The use of app information and alerts in the Active group was associated with an increase in TIR (+8%; P = 0.026). We observed a -3.9 (P = 0.1352) and -5.4 (P = 0.032) reduction per month in the number of missed and mistimed insulin doses in the overall population, respectively. Most of the items of the Insulin Treatment Satisfaction Questionnaire (ITSQ) improved after 4 weeks of Insulclock use. This pilot study points out an improvement in glycemic levels, adherence, and satisfaction in T1DM patients, supporting the development of clinical trials powered to confirm these effects.

Insulclock: A Novel Insulin Delivery Optimization and Tracking System.

BACKGROUND: Achieving and maintaining controlled glycemic levels are challenging in people with insulin-treated diabetes mellitus, suboptimal insulin injections being the main obstacle to treatment success. METHODS: This research article presents the main functionalities and performance tests on Insulclock®, an electronic device plugged into insulin pens and connected with a smartphone app to improve insulin management. Insulclock tracks the date, time of day, dose, type of insulin, temperature, and duration of insulin injections. Information is stored in the device memory and is available for analysis by patients and health care providers. Insulclock device also has a reminder system with visual and acoustic alerts to reduce insulin omissions and mistiming. RESULTS: The main performance tests reveal that Insulclock can detect seven types of insulin pens with a 97% correct classification rate. Among 556 injections, most of the doses were accurately detected (deviation = 0), with relative errors ranging from 3% to 7% across different dosages. The duration of injections recorded by this device strongly correlated with that detected by an external chronometer (R2 = 0.99, root-mean-square deviation [RMSD] = 0.39). Moreover, the precision of the temperature sensor was evidenced by high correlation of temperatures detected by Insulclock and by an external thermometer (Pearson's R2 = 0.90, RMSD = 0.45). CONCLUSIONS: Insulclock is a novel device capable of tracking dosing, timing, and missing insulin injections. The promising capabilities it offers for diabetes mellitus self-management may help health care providers, researchers, and insulin users avoid frequent errors in insulin administration.

Profile of semaglutide in the management of type 2 diabetes: design, development, and place in therapy.

Type 2 diabetes mellitus (T2DM) has become one of the leading causes of morbidity and mortality in developed countries. Low efficacy, weight gain, and hypoglycemia are the main pitfalls of previous treatments for T2DM. New therapies have been designed with the aim of improving the results in efficacy and quality of life. Glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1 RA) increase glucose-dependent insulin secretion, decrease gastric emptying, and reduce postprandial glucagon secretion. The last GLP-1 RA approved by the US Food and Drug Administration and European Medicines Agency was semaglutide. This review describes its pharmacology, core clinical data coming from the randomized controlled trials included in the development program, proven cardiovascular benefits, safety issues, and precautions for the use of semaglutide in special populations. Additionally, an overview of the positioning of semaglutide in T2DM therapy and practical issues regarding semaglutide initiation are offered.

Psychometric properties of the portuguese version of the chronic urticaria quality of life questionnaire (CU-Q2oL).

BACKGROUND: Chronic urticaria is defined as the appearance of urticarial lesions and/or angioedema during a period of more than six weeks. We aimed at developing the Portuguese version of the Chronic Urticaria Quality of Life Questionnaire (CU-Q2oL) and at testing its reliability and the content, construct and criterion validity. METHODS: The forward-backward approach to a linguistic equivalence was followed, after which a clinical review and a cognitive debriefing with patients were performed. The intraclass correlation coefficient checked test-retest reliability with patients filling the same questionnaire with one week apart and the Cronbach's alpha indicator assessed the internal consistency. Construct validity was tested by an exploratory factor analysis and by hypothesis tests involving sociodemographic and clinical patient characteristics, including the urticaria control test (UCT). On the other hand, criterion validity was tested through correlations with the Short-Form Health Survey SF-36, EQ-5D-5 L, and the Dermatology Quality of Life Index (DLQI). RESULTS: A total of 162 patients from seven hospital units were included. The mean (standard deviation) age was 42.6 (13.3) and 81.6% were female. CU-Q2oL was entirely filled by all respondents. Internal consistency was 0.947 for the overall score, ranging from 0.661 (limits) to 0.899 (sleep problems) and the corresponding reproducibility indicator was 0.910, based on 23 patients and ranging from 0.711 (swelling) and 0.957 (looks). Exploratory factor analysis in general confirmed the original structure originally obtained by the authors. All CU-Q2oL dimensions were highly correlated with DLQI Index and differentiated well between males and females, and between different levels of wheals and pruritus. In addition, moderate negative correlations were found between Cu-Q2oL scores and the dimensions from SF-36 and EQ-5D-5 L. CONCLUSIONS: The satisfactory metric properties confirmed the cultural adaptation and validity of CU-Q2oL into Portuguese population, providing the clinicians with a valid tool to evaluate the impact of chronic urticaria on patient's QoL and therefore adjust their treatment. TRIAL REGISTRATION NUMBER: Not applicable.

Safety and Efficacy of DPP4 Inhibitor and Basal Insulin in Type 2 Diabetes: An Updated Review and Challenging Clinical Scenarios.

The safety and efficacy of dipeptidyl peptidase-4 (DPP4) inhibitors as monotherapy or in combination with other oral antidiabetic agents or basal insulin are well established. DPP4 inhibitors stimulate glucose-dependent insulin secretion and inhibit glucagon production. As monotherapy, they reduce the hemoglobin A1c level by about 0.6-0.8%. The addition of a DPP4 inhibitor to basal insulin is an attractive option, because they lower both postprandial and fasting plasma glucose concentrations without increasing the risk of hypoglycemia or weight gain. The present review summarizes the extensive evidence on the combination therapy of DPP4 inhibitors and insulin-based regimens in patients with type 2 diabetes. We focus our discussion on challenging clinical scenarios including patients with chronic renal impairment, elderly persons and hospitalized patients. The evidence indicates that these drugs are highly effective and safe in the elderly and in the presence of mild, moderate and severe renal failure improving glycemic control with low risk of hypoglycemia. In addition, several randomized-controlled trials have shown that the use of DPP4 inhibitors in combination with basal insulin represents an alternative to the basal-bolus insulin regimen in hospitalized patients with type 2 diabetes.

Relationship between "a body shape index (ABSI)" and body composition in obese patients with type 2 diabetes.

BACKGROUND: Obesity is known to be related to the development of type 2 diabetes mellitus (T2D). The most commonly used anthropometric indicator (body mass index [BMI]) presents several limitations such as the lack of possibility to distinguish adipose tissue distribution. Thus, this study examines the suitability of a body shape index (ABSI) for prediction of body composition and sarcopenic obesity in obese or overweight T2D subjects. METHODS: Cross-sectional study in 199 overweight/obese T2D adults. Anthropometric (BMI, ABSI) and body composition (fat mass [FM], fat-free mass [FFM], fat mass index [FMI] and fat-free mass index, and the ratio FM/FFM as an index of sarcopenic obesity) data was collected, as well as metabolic parameters (glycated haemoglobin [HbA1c], mean blood glucose, fasting plasma glucose [FPG], high-density-lipoprotein cholesterol [HDL], low-density-lipoprotein cholesterol, total cholesterol, and triglycerides [TG] levels; the ratio TG/HDL was also calculated as a surrogate marker for insulin resistance). RESULTS: ABSI was significantly associated with age and waist circumference. It showed a statistically significant correlation with BMI exclusively in women. Regarding body composition, in men, ABSI was associated with FM (%), while in women it was associated with both FM and FFM. Both males and females groups with high ABSI scores were significantly older (men: 59.3 ± 10.8 vs 54.6 ± 10.1, p ≤ 0.05; women: 65.1 ± 9.8 vs 58.1 ± 13.3, p ≤ 0.005) and showed lower FFM values (men: 62.3 ± 9.0 vs 66.2 ± 9.3, p ≤ 0.05; women: 48.7 ± 5.6 vs 54.5 ± 8.9, p ≤ 0.001) compared with low-ABSI groups. Multiple linear regression revealed that ABSI independently predict FMI and the FM/FFM ratio in women. Sarcopenic obesity was identified in 70 (36.5%) individuals according to the FM/FFM ratio. The AUROC of ABSI was 63.1% (95% CI 54.6-71.6%; p = 0.003) and an ABSI value of 0.083 m11/6 kg-2/3 was the optimal threshold in discriminating patients with sarcopenic obesity (sensitivity: 48%, specificity: 73%). Moreover, a significant association between ABSI and FPG was found in men. CONCLUSIONS: ABSI could be useful to identify visceral and sarcopenic obesity in overweight/obese adults with T2D, adding some relevant clinical information to traditional anthropometric measures.
