Improved outcome of patients with diabetes mellitus with good glycemic control in the cardiac intensive care unit: a retrospective study.

BACKGROUND: Diabetes mellitus (DM) is a prevalent metabolic disease characterized by chronic hyperglycemia. A primary burden of DM is related to its long-term complications, which have been shown to impact the course of hospitalization and to influence patients' outcome. AIM: To assess the role of in-hospital glucose control on length of stay, 30-days and 1-year mortality. METHODS: This is a retrospective study that included patients admitted to the cardiac intensive care unit (CICU) of the Edith Wolfson Medical Centre between 01 January, 2010 and 31 December 2013. Blood glucose was measured by glucometer and fed into an interactive database. Glucose status was referred to as controlled when more than 50% of a given patients glucose values were between 71 and 200 mg/dL. Chisquared tests were used to assess the distribution of categorical variables, while the ttest was applied for continuous variables. A multivariate logistic regression model was used to analyze the association between glucose control and mortality. Cox regression was conducted to assess survival and 1-year mortality. RESULTS: 2466 patients were admitted to the CICU over the study period, of which 370 had concomitant diabetes mellitus. Controlled glucose status was associated with shorter length of hospital stay (1.6 ± 1.7 versus 2.6 ± 3.0, p < 0.001), reduced 30-day mortality (0.7% versus 4.6%, p < 0.001), and improved 1-year mortality (2.2% versus 7.5%, p < 0.001). Moreover, attainment of glucose control was independently associated with a significant decrease in 1-year mortality (OR = 0.371, 95% CI 0.140-0.988, p = 0.047). CONCLUSION: In-hospital control of glucose parameters is associated with shorter length of hospital stay, and lowered 30-day and 1-year mortality. An effort to maintain glucose levels within reference ranges is warranted in critically ill patients to reduce mortality.

The role of insulin pump therapy for type 2 diabetes mellitus.

Many patients with type 2 diabetes fail to achieve adequate glucose control despite escalation of treatment and combinations of multiple therapies including insulin. Patients with long-standing type 2 diabetes often suffer from the combination of severe insulin deficiency in addition to insulin resistance, thereby requiring high doses of insulin delivered in multiple injections to attain adequate glycemic control. Insulin-pump therapy was first introduced in the 1970s as an approach to mimic physiological insulin delivery and attain normal glucose in patients with type 1 diabetes. The recent years have seen an increase in the use of this technology for patients with type 2 diabetes. This article summarizes the clinical studies evaluating insulin pump use in patients with type 2 diabetes and discusses the benefits and shortcomings of pump therapy in this population.

Error in Drugs Consumption Among Older Patients.

The cost effectiveness of generic drugs has promoted their use worldwide. However, the large variety of bioequivalent generic and brand-name drugs found in the marketplace increases the complexity and frequency of mistakes in drug consumption. This clinical study investigated the prevalence of various mistakes in drug consumption by patients using a hospital setting. This prospective clinical trial used a hospital setting to identify errors in drug consumption. Six hundred patients who were hospitalized for a minimum of 48 hours in the Internal Medicine Departments were checked at various time points. The medications prescribed by their physician was determined and compared to the medications each patient carried on their person for de facto consumption. Drug consumption errors were found in 13 cases (2.17%), most of which involved duplicate drugs. In 6 of these (46.1%), patients consumed different drugs from the same therapeutic family. In 5 cases (38.5%), patients used chemically similar medications with different names, and in 2 cases (15.4%), patients consumed different drugs from various therapeutic families to treat the same medical condition. Ten of the thirteen cases (76.9%) had the potential to cause serious adverse drug events. More errors were found in female patients (53.8%), elderly patients, and those consuming a large variety of drugs. Variations in names, colors, shapes, and sizes of various drugs cause confusion and errors in drug consumption among patients. Some of these errors have the potential to cause severe, adverse drug effects and can increase morbidity and mortality worldwide.

Random blood glucose screening at a public health station encouraged high risk subjects to make lifestyle changes.

BACKGROUND: Screening and early diagnosis of prediabetes and diabetes can prevent or delay disease onset and complications. To that end, a free public health station was established in a large, government medical centre. This study evaluated the long-term outcomes of abnormal random blood glucose results among patients with no history of diabetes or prediabetes. METHODS: The Diabetes Unit supervised a public dysglycaemia and hypertension screening station. Participants with blood glucose >140 mg/dL and no history of diabetes or prediabetes were contacted by telephone for follow-up. RESULTS: Among screened subjects, 868 (average age 57.5±12 years) had a random blood glucose level >140 mg/dL and 341 (39.3%) responded to the telephone survey. Of these, 313 (91.8%) subsequently had fasting blood glucose measured at their health maintenance organisation (HMO), of which 101 (32.3%) were abnormal. A total of 173 (51%) respondents initiated interventions: 59 (17.3%) antidiabetic treatment; 145 (42.5%) sugar-restricted diet; and 96 (28.2%) a physical activity programme. Of patients with abnormal fasting blood glucose, 17 (14.5%) reported having had this result previously compared with 9 (4.2%) with normal fasting glucose (P=.001). Among respondents, 216 (63.3%) stated the screening was effective and 273 (80.1%) would recommend it. CONCLUSION: The station was effective in promoting additional screening among high-risk age groups and encourages subjects to make lifestyle changes. Operating the screening station is simple and effective; therefore it may serve as a complementary step in promoting community healthcare.

Prevalence of undiagnosed hyperglycaemia in patients presenting to the Department of Emergency Medicine with no known history of diabetes.

BACKGROUND: Diabetes is considered a major epidemic of the 21st century. Usually, diabetes begins asymptomatically and the diagnosis takes place an average of 8-12 years after the onset of dysglycaemia. Blood check for glucose is taken at different medical setting, whether at the fasting condition or randomly. Previous studies had shown that abnormal blood glucose predicts future diabetes. Hence, medical staff should consider taking reasonable actions in patients with abnormal blood glucose. OBJECTIVE: To assess the prevalence of hyperglycaemia in patients presenting to the Department of Emergency Medicine (DEM) with no known history of diabetes, and to evaluate how often were they recommended following this up as an outpatient by the medical staff. DESIGN: A cross-sectional study examined the medical records of adult patients referred to the DEM during 1 November 2011-31 January 2012. PARTICIPANTS: Patients with random blood glucose ≥140 mg/dL and no known history of diabetes were included in the study. The discharge letter was examined for the presence of instructions to conduct further follow up. KEY RESULTS: A total of 16 784 patients presented to the DEM. Of these, 402 patients (2.4%) without known diabetes were hyperglycaemic, 346 patients had blood glucose levels ≥140 mg/dL and 56 patients had blood glucose levels above 200 mg/dL. Only 35 of the 402 included patient files (8.7%) contained instructions for further investigation. There was no statistically significant difference between those who received a letter for further follow up compared with those who did not receive it with respect to age, sex or blood glucose levels. CONCLUSION: Over 2% of patients who presented to the DEM were hyperglycaemic, without a prior diagnosis of diabetes. A small per cent was recommended to have outpatient follow-up. This represents a missed opportunity for earlier diagnosis of diabetes and emphasised the need for raising medical staff awareness concerning abnormal blood glucose and its implication.

High-energy breakfast with low-energy dinner decreases overall daily hyperglycaemia in type 2 diabetic patients: a randomised clinical trial.

AIMS/HYPOTHESIS: High-energy breakfast and reduced-energy dinner (Bdiet) significantly reduces postprandial glycaemia in obese non-diabetic individuals. Our objective was to test whether this meal schedule reduces postprandial hyperglycaemia (PPHG) in patients with type 2 diabetes by enhancing incretin and insulin levels when compared with high-energy dinner and reduced-energy breakfast (Ddiet). METHODS: In a randomised, open label, crossover design performed in a clinic setting, 18 individuals (aged 30-70 years with BMI 22-35 kg/m(2)) with type 2 diabetes (<10 years duration) treated with metformin and/or diet were given either Bdiet or Ddiet for 7 days. Participants were randomised by a person not involved in the study using a coin flip. Postprandial levels of plasma glucose, insulin, C-peptide and intact and total glucagon-like peptide-1 (iGLP-1 and tGLP-1) were assessed. The Bdiet included 2,946 kJ breakfast, 2,523 kJ lunch and 858 kJ dinner. The Ddiet comprised 858 kJ breakfast, 2,523 kJ lunch and 2,946 kJ dinner. RESULTS: Twenty-two individuals were randomised and 18 analysed. The AUC for glucose (AUCglucose) throughout the day was 20% lower, whereas AUCinsulin, AUCC-peptide and AUCtGLP-1 were 20% higher for the Bdiet than the Ddiet. Glucose AUC0-180min and its peak were both lower by 24%, whereas insulin AUC0-180min was 11% higher after the Bdiet than the Ddiet. This was accompanied by 30% higher tGLP-1 and 16% higher iGLP-1 levels. Despite the diets being isoenergetic, lunch resulted in lower glucose (by 21-25%) and higher insulin (by 23%) with the Bdiet vs Ddiet. CONCLUSIONS/INTERPRETATION: High energy intake at breakfast is associated with significant reduction in overall PPHG in diabetic patients over the entire day. This dietary adjustment may have a therapeutic advantage for the achievement of optimal metabolic control and may have the potential for being preventive for cardiovascular and other complications of type 2 diabetes. Trial registration ClinicalTrials.gov NCT01977833 Funding No specific funding was received for the study.

Incretin, insulinotropic and glucose-lowering effects of whey protein pre-load in type 2 diabetes: a randomised clinical trial.

AIMS/HYPOTHESIS: Since protein ingestion is known to stimulate the secretion of glucagon-like peptide-1 (GLP-1), we hypothesised that enhancing GLP-1 secretion to harness its insulinotropic/beta cell-stimulating activity with whey protein pre-load may have beneficial glucose-lowering effects in type 2 diabetes. METHODS: In a randomised, open-label crossover clinical trial, we studied 15 individuals with well-controlled type 2 diabetes who were not taking any medications except for sulfonylurea or metformin. These participants consumed, on two separate days, 50 g whey in 250 ml water or placebo (250 ml water) followed by a standardised high-glycaemic-index breakfast in a hospital setting. Participants were randomised using a coin flip. The primary endpoints of the study were plasma concentrations of glucose, intact GLP-1 and insulin during the 30 min following meal ingestion. RESULTS: In each group, 15 patients were analysed. The results showed that over the whole 180 min post-meal period, glucose levels were reduced by 28% after whey pre-load with a uniform reduction during both early and late phases. Insulin and C-peptide responses were both significantly higher (by 105% and 43%, respectively) with whey pre-load. Notably, the early insulin response was 96% higher after whey. Similarly, both total GLP-1 (tGLP-1) and intact GLP-1 (iGLP-1) levels were significantly higher (by 141% and 298%, respectively) with whey pre-load. Dipeptidyl peptidase 4 plasma activity did not display any significant difference after breakfast between the groups. CONCLUSIONS/INTERPRETATION: In summary, consumption of whey protein shortly before a high-glycaemic-index breakfast increased the early prandial and late insulin secretion, augmented tGLP-1 and iGLP-1 responses and reduced postprandial glycaemia in type 2 diabetic patients. Whey protein may therefore represent a novel approach for enhancing glucose-lowering strategies in type 2 diabetes. Trial registration ClinicalTrials.gov NCT01571622 Funding The Israeli Ministry of Health and Milk Council funded the research.

Atopic dermatitis in Israeli adolescents - a large retrospective cohort study.

Prevalence of atopic dermatitis (AD) has been studied mainly in infants and young children. Surveys on AD in adolescents and adults are based largely on self-reported questionnaires and cohorts of different ages, precluding meaningful comparisons and conclusions. We aimed to provide data on the prevalence of AD and its relation to demographic factors in adolescents. A large database of youths eligible for military service was searched for subjects one year before service at the age of 18. Parameters included country of origin, age of immigration to Israel, education, and presence and severity of AD. AD rose 3-fold for both genders over the study period 1998-2008 (0.4-1%). The increase was higher in females (0.5-1.2%) than males (0.3-0.9%). Mild and moderate disease was higher in females than males. Severe AD was rarely noted. Russian (OR = 1.47), Asian (OR = 1.15) and Euro-American (OR = 1.26) origins had highest association with AD. Immigrants after age 7 had higher association with AD than Israeli-born subjects and immigrants before age 7 (1.88 vs. 1.33). More years of education was significantly associated with high prevalence of AD. The increased prevalence of AD during the 11-year period underscores the need for awareness of the condition in this population, in which AD affects health and quality of life.

Weight disorders and associated morbidity among young adults in Israel 1990-2003.

BACKGROUND: The aim of this study was to evaluate the change in prevalence of weight disorders and associated morbidity among young adults. METHODS: Records of 1,021,211 subjects aged 17, who underwent a medical examination, were included. RESULTS: Among female subjects the prevalence of underweight increased steadily from 13.2% to 15.6%. No statistically significant trend was found among male subjects. Among male subjects a twofold increase in the prevalence of obesity was observed, while among female subjects there was an increase of 57%. In obese versus normal-weight male subjects the OR, adjusted for origin, education and year of recruitment, of having high blood pressure, diabetes type 2 and type 1 and hyperlipidemia were 4.1 (95%CI 3.89-4.34), 5.56 (5.09-6.07), 1.00 (0.30-3.27) and 16.07 (8.29-31.15), respectively. For obese female nominees the OR were 5.56 (95%CI 5.09-6.07), 4.42 (3.90-5.00), 3.59 (0.77-16.87) and 9.00 (4.36-18.60), respectively. CONCLUSION: A significant increase in prevalence of obesity was observed with an increased risk of having diabetes type 2, hyperlipidemia and high blood pressure. An increase in the prevalence of being underweight was observed in female subjects. Policy makers have to plan appropriate effective interventions that will promote a healthy lifestyle in adolescents and reduce obesity on the one hand, and avoid the fashion for being underweight, with its possible development to anorexia, on the other.

A retrospective study of the eligibility for tonsillectomy.

BACKGROUND: The criteria for tonsillectomy for recurrent tonsillitis were established by prospective studies in the pediatric population and are applied to adults as well. No studies have been conducted to assess whether these guidelines are followed. OBJECTIVES: To examine the eligibility for tonsillectomy of tonsillectomized patients who were referred because of recurrent acute tonsillitis. METHODS: A retrospective case series in an ambulatory military otolaryngology clinic was conducted, and the medical records of 44 tonsillectomized patients who suffered from throat infections during the year before surgery were analyzed. The number of tonsillar infections that met the referral criteria was counted. RESULTS: The average number of throat infections that met the referral criteria was 1.89 per year. The average number of visits to the clinic due to upper respiratory tract infection was 12.92 (range 2-36) per year. The average number of visits for any cause was 45.13 (range 6-64) per year. One patient with eight documented throat infections met the criterion of more than six infections in the last year. CONCLUSION: Although the referral criteria were not strictly met, we speculate that surgery was probably beneficial. This study shows that the indications for tonsillectomy referral are not strictly followed, and that new criteria for referral of adults for tonsillectomy need to be established.

Wireless capsule endoscopy in Israeli Defense Force: two years of experience.

OBJECTIVES: Evaluate outcome and diagnostic yield of capsule endoscopy (CE) in soldiers with suspected small bowel disease, in comparison to traditional diagnostic procedures. METHODS: 27 consecutive soldiers who underwent CE between June 2002 and February 2004 were enrolled. Results of CE were compared to standard techniques. RESULTS: CE was normal in 16 patients (59.3%). Findings could not explain any signs or symptoms were observed in 11.1%. Definite diagnosis of Crohn's disease was obtained in 11.1%. Patients (62.5%) with a triad of symptoms (abdominal pain, changed bowel habits, and gastrointestinal bleeding) versus 15.8% without that triad, had either diagnostic or suspicious CE (p = 0.015). Diagnostic yield of CE was higher in gastrointestinal bleeding (25%) in comparison to suspected Crohn's disease (15.8%). Three out of 6 patients (50%) with suggestive findings of Crohn's disease in the preliminary workup were diagnosed as definite Crohn's by capsule endoscopy. CE allowed the physician to conclude workup in 71% patients. CONCLUSION: CE should be used when obscure gastrointestinal bleeding or Crohn's disease is suspected without a conclusive diagnosis. Furthermore, when a triad of symptoms exists CE should be considered as first line examination.

[Development of an evidence-based managerial decision aid to assist in the provision of secondary medical services in the Israel Defense Forces (IDF)].

BACKGROUND: Increasing global expenditures on health, together with increased patient demand for quality and service, have created a need for health care management tools based on economic and quaLity-based criteria. Despite the recognition of this need, decision-support tools are Lacking. In the Israel Defense Forces (IDF), policy change and budgetary and quality constraints necessitated the development of an evidence-based managerial decision aid, to assist in providing medical services at acceptable quality and availability leveLs, while addressing economic concerns. OBJECTIVE: To develop a decision-support model for the IDF Medical Corps, that balances the conflicting considerations of service avaiLabiLity and cost. METHODS: The authors developed a manageriaL model to characterize regional secondary medical care, and to compare it to country-wide patterns and to historic regional patterns. Secondary care systems were then analyzed by specialty. Finally, the relative costs of medical encounters for each speciaLty were anaLyzed. RESULTS: Core specialties examined included dermatology, orthopedics and otolaryngology. Two-thirds of all referrals to core specialists were made to intra-organizational resources. Furthermore, several intra-organizationaL clinics were found to have short waiting times and low output indices. In response to the application of the model, IDF Medical Corps policy was updated and suppliers were reprioritized, yielding substantial savings of up to NIS 5.5 million in 2006 alone. This cost saving enabled budgetary reallocation and alternative investment in the emergency and primary health care systems. CONCLUSION: Applying efficient managerial tools can lead to cost savings and to increased quality and availability of services. These tools must effectively follow changes in the dynamics of the health care system. These changes are to be impLemented rapidly, in order to provide practical guidance for medical administrators and to enable them to infLuence the real-time utiLization of medical services.

Hypoglycemia- simplifying the ways to predict an old problem in the general ward.

OBJECTIVE: To examine the association between hypoglycemic events and inpatient and outpatient mortality rates, and to characterize the profile of patients with diabetes who develop hypoglycemia during hospitalization in order to identify risk factors and potentially avoid it. RESEARCH DESIGN AND METHODS: This retrospective cohort study analyzed data of 3410 patients with diabetes hospitalized during 2012. The associations among biochemical measures, severity of hypoglycemia, inpatient length of stay, and mortality during hospitalization, one month and within one year after discharge were evaluated. RESULTS: Hypoglycemia was observed in 18.5% (633/3410) of patients with diabetes, 83% (529/633) with mild/moderate hypoglycemic values. Adjusted for age and sex, the 30-day mortality rate after discharge was higher in the group with mild/moderate hypoglycemia (HR = 1.749, CI 1.288-2.374, p < 0.001) and in the group with severe hypoglycemia (HR = 3.390, CI 2.332-6.100, p < 0.001). The mortality rate at the one-year follow-up was higher in the group with mild/moderate hypoglycemia (HR = 1.749, CI 1.288-2.374, p < 0.001) and in the group with severe hypoglycemia (HR = 3.390, CI 2.332-6.100, p < 0.001). In multivariate analysis, hemoglobin and albumin below normal values, and creatinine values above the upper limit were strongly associated with hypoglycemia (OR 1.35, 95%CI 1.1-1.6, p < 0.03; OR 1.6, 95%CI 1.33-1.89, p < 0.001; OR 1.3, 95%CI 1.08-1.55, p < 0.04, respectively). CONCLUSIONS: Hospitalized patients with diabetes and low hemoglobin, low albumin or high creatinine levels are at increased risk of developing significant hypoglycemia. Identifying accurate high-risk factors in order to intervene early and efficiently can prevent life-threatening complications.

Reduction in Glycated Hemoglobin and Daily Insulin Dose Alongside Circadian Clock Upregulation in Patients With Type 2 Diabetes Consuming a Three-Meal Diet: A Randomized Clinical Trial.

OBJECTIVE: In type 2 diabetes, insulin resistance and progressive ß-cell failure require treatment with high insulin doses, leading to weight gain. Our aim was to study whether a three-meal diet (3Mdiet) with a carbohydrate-rich breakfast may upregulate clock gene expression and, as a result, allow dose reduction of insulin, leading to weight loss and better glycemic control compared with an isocaloric six-meal diet (6Mdiet). RESEARCH DESIGN AND METHODS: Twenty-eight volunteers with diabetes (BMI 32.4 ± 5.2 kg/m2 and HbA1c 8.1 ± 1.1% [64.5 ± 11.9 mmol/mol]) were randomly assigned to 3Mdiet or 6Mdiet. Body weight, glycemic control, continuous glucose monitoring (CGM), appetite, and clock gene expression were assessed at baseline, after 2 weeks, and after 12 weeks. RESULTS: 3Mdiet, but not 6Mdiet, led to a significant weight loss (-5.4 ± 0.9 kg) (P < 0.01) and decreased HbA1c (-12 mmol/mol [-1.2%]) (P < 0.0001) after 12 weeks. Fasting glucose and daily and nocturnal glucose levels were significantly lower on the 3Mdiet. CGM showed a significant decrease in the time spent in hyperglycemia only on the 3Mdiet. Total daily insulin dose was significantly reduced by 26 ± 7 units only on the 3Mdiet. There was a significant decrease in the hunger and cravings only in the 3Mdiet group. Clock genes exhibited oscillation, increased expression, and higher amplitude on the 3Mdiet compared with the 6Mdiet. CONCLUSIONS: A 3Mdiet, in contrast to an isocaloric 6Mdiet, leads to weight loss and significant reduction in HbA1c, appetite, and overall glycemia, with a decrease in daily insulin. Upregulation of clock genes seen in this diet intervention could contribute to the improved glucose metabolism.

The prevalence of gastrointestinal diseases in Israeli adolescents and its association with body mass index, gender, and Jewish ethnicity.

OBJECTIVE: The objectives of this study were to describe gastrointestinal (GI) disease prevalence in Israeli adolescents, and possible associations between prevalence and body mass index (BMI), sex and Jewish ethnicity. DESIGN: A retrospective analysis of screening for GI disease performed by the Israeli Defense Forces recruiting office between 1998 and 2003. SETTING: Screening was performed at the recruiting office, and included detailed history and physical examination performed by a general practitioner. Further testing was performed as needed and the final diagnosis was established by a gastroenterologist at the recruiting office. PATIENTS: Seventeen-year-old Israeli nationals. RESULTS: During the study period, 466,855 (58.5% male) adolescents were screened for GI disease. Peptic ulcer disease, irritable bowel syndrome, and nonulcer dyspepsia were the most prevalent disorders affecting 466/10, 460/10, and 296/10, respectively. There was an increase in the prevalence of lactose intolerance during the study period and also an increase in the prevalence of peptic ulcer disease in females. The prevalence of inflammatory bowel disease has also increased from 100/10 to 149/10, although this trend failed to reach statistical significance (P=0.097). Higher BMI was associated with statistically significant higher prevalence rates of gastroesophageal reflux disease (P<0.05). A stronger association in females was found in gallbladder disease (P<0.001). Lower BMI was associated with higher prevalence rates of irritable bowel syndrome (P<0.001), and higher rates of inflammatory bowel disease and lactose intolerance in males (P<0.01 and <0.001, respectively). CONCLUSIONS: GI diseases are not uncommon among adolescents, and for some disorders prevalence is rising. The association between BMI and prevalence has been further clarified.

Lifestyle intervention program benefits children with overweigh compared to children with obesity.

BACKGROUND: Lifestyle weight loss interventions represent the mainstay of treating children with obesity. Long-term follow-up studies of intervention programs are scarce. This study assessed the long-term effects and identified factors associated with significant weight loss. METHODS: This prospective, observational study involved 165 children with body mass index (BMI) z-score ≥1.5 who participated in after-school intervention program. MAIN OUTCOME MEASURE: change in BMI z-scores; decreased BMI z-score ≥0.5 units was defined as clinically significant. RESULTS: At baseline, 55/165 (33.3%) had BMI z-score 1.5-2 and 98 (59.4%) had BMI z-score >2. At follow-up (mean 5.4±1.4 years), 80 (48.5%) had a clinically significant reduction in BMI z-score, while 56 (33.9%) reported a mildly decrease in BMI z-score of 0-0.5 and 29 (17.6%) reported increased BMI z-score. Lower BMI z-score at baseline and participation in sport activity at follow-up were associated with long-term decrease in BMI z-score. Participation in additional post-intervention weight control programs was correlated with weight gain. CONCLUSIONS: Intervention program was associated with long-term improvement in weight control, especially in children with mild obesity. Physical activity was related to long-term success. Participation in an additional intervention program was associated with failure of weight control.

Glycemic Control and Quality of Life Following Cataract Surgery in Patients with Type 2 Diabetes and without Maculopathy.

OBJECTIVE: To assess whether cataract removal surgery will improve glycemic control and quality of life in patients with diabetes. METHODS: A prospective longitudinal study of 28 patients with type 2 diabetes and without diabetic retinopathy scheduled for cataract removal surgery. During the 4 months of follow-up, measurements of glycated hemoglobin (HbA1c) were obtained and assessment of quality of life was performed using two questionnaires: The EuroQoL 5-Dimension (EQ-5D®) and the Multidimensional Diabetes Questionnaire (MDQ). RESULTS: HbA1c values decreased by approximately 0.45% following surgery (7.24% to 6.78%, P = 0.009). Younger patients reduced HbA1c significantly more than older patients (0.73% vs. 0.03%, respectively, P = 0.043). Younger age also correlated with better visual acuity improvement (R = -0.44, P = 0.02). Poor glycemic control prior to surgery correlated with better HbA1c reductions, with a 42% chance for reduction of at least 0.5% HbA1c in patients with preoperative HbA1c values of 7.5% and a 72% chance for reduction in patients with preoperative HbA1c values of 8.5%. Quality of life was improved by 14% following surgery, as noted in the MDQ results (33.9-38.7, P = 0.034) only. CONCLUSIONS: Cataract removal surgery may positively influence glycemic control and quality of life in type 2 diabetic patients without maculopathy. Younger patients achieved superior improvement in visual and glycemic outcomes. The results of this study highlight the need for frequent inquiry regarding eyesight deterioration in patients with diabetes.

Screening and treating amblyopia: are we making a difference?

PURPOSE: To determine the rate of amblyopia in native Jewish Israelis compared with those who immigrated from the former Soviet Union (U.S.S.R.) after they were 10 years of age. METHODS: Health records of all 16-year-old subjects examined in the Israel Defense Forces Recruitment Center between 1998 and 2003 were analyzed. The number of subjects with best corrected visual acuity (BCVA) of 6/12 or less in at least one eye among native Israelis and among those who immigrated to Israel from the U.S.S.R. after they were 10 years of age was determined. Subjects who had any ocular disease except cataract, corneal opacity, strabismus, or ptosis were excluded. RESULTS: Of 305,712 subjects examined between 1998 and 2003, 292,255 were enrolled in the study. Of those, 260,186 (89%) were born in Israel and 32,069 (11%) were born in the U.S.S.R. and immigrated to Israel after they were 10 years of age. There were 2565 (0.98%) native Israelis and 483 (1.5%) immigrants who had BCVA of 6/12 or less in at least one eye (chi(2) test, P < 0.00001). The rate of amblyopia among subjects who had refractive errors was 14.6% among immigrants, as opposed to 8.0% among native Israelis (P < 0.0001), whereas amblyopia rates among those with strabismus, cataract, or ptosis were similar in native Israelis and immigrants (34.4%, 38.6%, 12.8% as opposed to 34%, 37.5%, 15.4%, respectively, P = 0.5-0.61). CONCLUSIONS: The difference in the rate of refractive amblyopia as opposed to strabismic and deprivation amblyopia may be due to the difference in vision screening methods between both countries.

High-energy breakfast based on whey protein reduces body weight, postprandial glycemia and HbA1C in Type 2 diabetes.

Acute studies show that addition of whey protein at breakfast has a glucose-lowering effect through increased incretin and insulin secretion. However, whether this is a long-term effect in Type 2 diabetes is unknown. Fifty-six Type 2 diabetes participants aged 58.9±4.5 years, BMI 32.1±0.9 kg/m2 and HbA1C 7.8±0.1% (61.6±0.79 mmol/mol) were randomized to one of 3 isocaloric diets with similar lunch and dinner, but different breakfast: 1) 42 g total protein, 28 g whey (WBdiet, n=19); 2) 42 g various protein sources (PBdiet, n=19); or 3) high-carbohydrate breakfast, 17 g protein from various sources (CBdiet, n=18). Body weight and HbA1C were examined after 12 weeks. All participants underwent three all-day meal challenges for postprandial glycemia, insulin, C-peptide, intact glucagon-like peptide 1 (iGLP-1), ghrelin and hunger and satiety scores. Overall postprandial AUCglucose was reduced by 12% in PBdiet and by 19% in WBdiet, compared with CBdiet (P<.0001). Compared with PBdiet and CBdiet, WBdiet led to a greater postprandial overall AUC for insulin, C-peptide, iGLP-1 and satiety scores, while postprandial overall AUC for ghrelin and hunger scores were reduced (P<.0001). After 12 weeks, HbA1C was reduced after WBdiet by 0.89±0.05% (11.5±0.6 mmol/mol), after PBdiet by 0.6±0.04% (7.1±0.31 mmol/mol) and after CBdiet by 0.36±0.04% (2.9±0.31 mmol/mol) (P<.0001). Furthermore, the participants on WBdiet lost 7.6±0.3 kg, PBdiet 6.1±0.3 kg and CBdiet 3.5±0.3 kg (P<.0001). Whey protein-based breakfast is an important adjuvant in the management of Type 2 diabetes.

Influences of Breakfast on Clock Gene Expression and Postprandial Glycemia in Healthy Individuals and Individuals With Diabetes: A Randomized Clinical Trial.

OBJECTIVE: The circadian clock regulates glucose metabolism by mediating the activity of metabolic enzymes, hormones, and transport systems. Breakfast skipping and night eating have been associated with high HbA1c and postprandial hyperglycemia after lunch and dinner. Our aim was to explore the acute effect of breakfast consumption or omission on glucose homeostasis and clock gene expression in healthy individuals and individuals with type 2 diabetes. RESEARCH DESIGN AND METHODS: In a crossover design, 18 healthy volunteers and 18 volunteers with 14.5 ± 1.5 years diabetes, BMI 30.7 ± 1.1 kg/m2, and HbA1c 7.6 ± 0.1% (59.6 ± 0.8 mmol/mol) were randomly assigned to a test day with breakfast and lunch (YesB) and a test day with only lunch (NoB). Postprandial clock and clock-controlled gene expression, plasma glucose, insulin, intact glucagon-like peptide 1 (iGLP-1), and dipeptidyl peptidase IV (DPP-IV) plasma activity were assessed after breakfast and lunch. RESULTS: In healthy individuals, the expression level of Per1, Cry1, Rorα, and Sirt1 was lower (P < 0.05) but Clock was higher (P < 0.05) after breakfast. In contrast, in individuals with type 2 diabetes, Per1, Per2, and Sirt1 only slightly, but significantly, decreased and Rorα increased (P < 0.05) after breakfast. In healthy individuals, the expression level of Bmal1, Rorα, and Sirt1 was higher (P < 0.05) after lunch on YesB day, whereas the other clock genes remained unchanged. In individuals with type 2 diabetes, Bmal1, Per1, Per2, Rev-erbα, and Ampk increased (P < 0.05) after lunch on the YesB day. Omission of breakfast altered clock and metabolic gene expression in both healthy and individuals with type 2 diabetes. CONCLUSIONS: Breakfast consumption acutely affects clock and clock-controlled gene expression leading to normal oscillation. Breakfast skipping adversely affects clock and clock-controlled gene expression and is correlated with increased postprandial glycemic response in both healthy individuals and individuals with diabetes.
