    Input: OBJECTIVE To prospect ively examine the effect of weight loss 1 year after  laparoscopic adjustable gastric b and surgery on a broad range of health outcomes in 50 diabetic subjects . RESEARCH DESIGN AND METHODS A total of 50 ( 17 men , 33 women ) of 51 patients with type 2 diabetes , from a total of 500 consecutive patients , were studied preoperatively and again 1 year after surgery . RESULTS Preoperative weight and BMI ( means + /- SD ) were 137 + /- 30 kg and 48.2 + /- 8 kg/m(2 ) , respectively ; at 1 year , weight and BMI were 110 + /- 24 kg and 38.7 + /- 6 kg/m(2 ) , respectively . There was significant improvement in all measures of glucose metabolism . Remission of diabetes occurred in 32 patients ( 64 % ) , and major improvement of glucose control occurred in 13 patients ( 26 % ) ; glucose metabolism was unchanged in 5 patients ( 10 % ) . HbA(1c ) was 7.8 + /- 3.2 % preoperatively and 6.2 + /- 2.7 % at 1 year ( P < 0.001 ) . Remission of diabetes was predicted by greater weight loss and a shorter history of diabetes ( pseudo r(2 ) = 0.44 , P < 0.001 ) . Improvement in diabetes was related to increased insulin sensitivity and beta-cell function . Weight loss was associated with significant improvements in fasting triglyceride level , HDL cholesterol level , hypertension , sleep , depression , appearance evaluation , and health-related quality of life . Early complications occurred in 6 % of patients ( wound infections in 4 % , respiratory support in 2 % ) , and late complications occurred in 30 % of patients ( gastric prolapse in 20 % , b and erosion in 6 % , and tubing leaks in 4 % ) . All late complications were successfully revised surgically . CONCLUSIONS Modern laparoscopic weight-loss surgery is effective in managing the broad range of health problems experienced by severely obese individuals with type 2 diabetes . Surgery should be considered as an early intervention Abstract OBJECTIVE : To examine the impact of a nurse-coordinated intervention delivered to patients with non-insulin-dependent diabetes mellitus between office visits to primary care physicians . DESIGN : R and omized , controlled trial . SETTING : Veterans Affairs general medical clinic . PATIENTS : 275 veterans who had NIDDM and were receiving primary care from general internists . INTERVENTION : Nurse-initiated contacts were made by telephone at least monthly to provide patient education ( with special emphasis on regimens and significant signs and symptoms of hyperglycemia and hypoglycemia ) , reinforce compliance with regimens , monitor patients ’ health status , facilitate resolution of identified problems , and facilitate access to primary care . MEASUREMENTS : Glycemic control was assessed using glycosylated hemoglobin ( GHb ) and fasting blood sugar ( FBS ) levels . Health-related quality of life ( HRQOL ) was measured with the Medical Outcomes Study SF-36 , and diabetes-related symptoms were assessed using patients ’ self-reports of signs and symptoms of hyper- and hypoglycemia during the previous month . MAIN RESULTS : At one year , between-group differences favored intervention patients for FBS ( 174.1 mg/dL vs 193.1 mg/dL , p=0.011 ) and GHb ( 10.5 % vs 11.1 % , p=0.046 ) . Statistically significant differences were not observed for either SF-36 scores ( p=0.66 ) or diabetes-related symptoms ( p=0.23 ) . CONCLUSIONS : The intervention , design ed to be a pragmatic , low-intensity adjunct to care delivered by physicians , modestly improved glycemic control but not HRQOL or diabetes-related symptoms OBJECTIVE To assess the efficacy of a lifestyle intervention program that can be readily translated into clinical practice for obese patients with type 2 diabetes . RESEARCH DESIGN AND METHODS The study consisted of a 12-month r and omized controlled trial of 147 health plan members with type 2 diabetes and obesity ( BMI > or=27 kg/m(2 ) ) . Participants were r and omized to lifestyle case management or usual care . Case management entailed individual and group education , support , and referral by registered dietitians ; intervention cost was US dollars 350 per person . Individuals treated with usual care received educational material . Both groups received ongoing primary care . Outcomes were difference between groups for change in weight ( kilograms ) , waist circumference ( centimeters ) , HbA(1c ) , fasting lipid levels , use of prescription medications , and health-related quality of life . RESULTS Case management result ed in greater weight loss ( P < 0.001 ) , reduced waist circumference ( P < 0.001 ) , reduced HbA(1c ) level ( P = 0.02 ) , less use of prescription medications ( P = 0.03 ) , and improved health-related quality of life ( P < 0.001 ) compared with usual care . The 12-month group difference in weight loss and waist circumference was 3.0 kg ( 95 % CI -5.4 to -0.6 ) and -4.2 cm ( -6.8 to -1.6 ) . HbA(1c ) differences were greatest at 4 months ( -0.59 % , P = 0.006 ) but not significant by 12 months ( -0.19 % , P = 0.45 ) . Participants in the case management group lowered their use of medications , primarily diabetes medications , by 0.8 medications per day more than participants treated with usual care ( P = 0.03 ) . In seven of nine quality -of-life domains , the case management group improved compared with usual care ( P < 0.05 ) . CONCLUSIONS Moderate-cost dietitian-led lifestyle case management may improve diverse health indicators among obese patients with type 2 diabetes OBJECTIVE To evaluate the impact of primary care group visits ( chronic care clinics ) on the process and outcome of care for diabetic patients . RESEARCH DESIGN AND METHODS We evaluated the intervention in primary care practice s r and omized to intervention and control groups in a large-staff model health maintenance organization ( HMO ) . Patients included diabetic patients > or = 30 years of age in each participating primary care practice , selected at r and om from an automated diabetes registry . Primary care practice s were r and omized within clinics to either a chronic care clinic ( intervention ) group or a  usual care ( control ) group . The intervention group conducted periodic one-half day chronic care clinics for groups of approximately 8 diabetic patients in their respective doctor 's practice .  Chronic care clinics consisted of st and ardized assessment s ; visits with the primary care physician , nurse , and clinical pharmacist ; and a group education/peer support meeting . We collected  self-report question  naires from patients and data from administrative systems . The question naires were mailed , and telephoned interviews were conducted for nonrespondents , at baseline and at 12 and 24 months ; we queried the process of care received , the satisfaction with care , and the health status of each patient . Serum cholesterol and HbA1c levels and health care use and cost data was collected from HMO administrative systems . RESULTS In an intention-to-treat analysis at 24 months , the intervention group had received significantly more recommended preventive procedures  and helpful patient education .  Of five primary health status indicators examined , two ( SF-36 general health and bed disability days ) were significantly better in the intervention group . Compared with control patients , intervention patients had slightly more primary care visits , but significantly fewer specialty and emergency room visits . Among intervention participants , we found consistently positive associations between the number of chronic care clinics attended and a number of outcomes , including patient satisfaction and HbA1c levels . CONCLUSIONS Periodic primary care sessions organized to meet the complex needs of diabetic patients imrproved the process of diabetes care and were associated with better outcomes OBJECTIVES The current study was conducted to compare the effectiveness of delivering diabetes education in either a group or individual setting using a consistent , evidence -based curriculum . RESEARCH DESIGN AND METHODS A total of 170 subjects with type 2 diabetes were r and omly assigned to either group ( n = 87 ) or individual ( n = 83 ) educational setting s. Subjects received education in four sequential sessions delivered at consistent time intervals over a 6-month period . Outcomes included changes in knowledge , self-management behaviors , weight , BMI , HbA(1c ) , health-related quality of life , patient attitudes , and medication regimen . Changes were assessed at baseline and after the 2-week , 3-month , and 6-month education sessions . RESULTS Both educational setting s had similar improvements in knowledge , BMI , health-related quality of life , attitudes , and all other measured indicators . HbA(1c ) decreased from 8.5 + /- 1.8 % at baseline to 6.5 + /- 0.8 % at 6 months ( P < 0.01 ) in the study population as a whole . Subjects assigned to the individual setting had a 1.7 + /- 1.9 % reduction in HbA(1c ) ( P < 0.01 ) , whereas subjects assigned to the group setting had a 2.5 + /- 1.8 % reduction in HbA(1c ) ( P < 0.01 ) . The difference in HbA(1c ) improvement was marginally greater in subjects assigned to group education versus individualized education ( P = 0.05 ) . CONCLUSIONS This study demonstrates that diabetes education delivered in a group setting , when compared with an individual setting , was equally effective at providing equivalent or slightly greater improvements in glycemic control . Group diabetes education was similarly effective in delivering key educational components and may allow for more efficient and cost-effective methods in the delivery of diabetes education programs AIM The aim of our study was to describe investigate and association between improved glycaemic control on quality of life ( QoL ) during 1 year of treatment in a sample of 94 Type 2 diabetic patients referred for insulin therapy to an outpatient department ( OPD ) . Treatment was aim ed at achieving acceptable glycaemic control by means of maximizing oral therapy , if necessary switching over to insulin therapy , and information and education provided by a diabetes specialist nurse and dietitian . METHODS QoL was measured using a disease-specific ( Diabetes Health Profile ( DHP ) ) and a generic question naire ( R AND -36 ) . After 1 year the medical examination and QoL measurements were repeated . The association between 1-year changes in QoL and achievement of good metabolic control ( final glycosylated haemoglobin ( HbA1c ) < or = 8 % ) , switch to insulin therapy , and presence of hyperglycaemic complaints at baseline was analysed after adjustment for appropriate confounders . RESULTS After 1 year , mean HbA1c was reduced from 10.4 % to 7.8 % . Also QoL improved in the total group . Patients who achieved good glycaemic control after 1 year ( 61 % ) improved in a similar manner as the others . Patients switched over to insulin ( 65 % ) improved in a similar manner as the others , but at the final examination they experienced more problems with social functioning and pain . Patients with hyperglycaemic complaints at baseline ( 49 % ) improved more in QoL than those without , especially in physical functioning , vitality and health change , but at the final examination still scored lower on a majority of the DHP and R AND -36 dimensions . CONCLUSION Symptoms of hyperglycaemia predict the strength of an association between improvements of glycaemic control and OBJECTIVE To compare the efficacy and safety of continuous subcutaneous insulin infusion ( CSII ) and multiple daily injection ( MDI ) in older adults with insulin-treated type 2 diabetes and to assess treatment satisfaction and quality of life . RESEARCH DESIGN AND METHODS Adults ( n = 107 ) > or = 60 years of age ( mean age 66 years ) with insulin-treated type 2 diabetes ( mean duration 16 years , BMI 32 kg/m(2 ) , and HbA(1C ) [ A1C ] 8.2 % ) were r and omized to CSII ( using insulin lispro ) or MDI ( using insulin lispro and insulin glargine ) in a two-center , 12-month , prospect i ve , r and omized , controlled clinical trial . Efficacy was assessed with A1C , safety by frequency of hypoglycemia , and treatment satisfaction and quality of life with the Diabetes Quality of Life Clinical Trial Question naire and the 36-item short-form health survey , version 2 . RESULTS Forty-eight CSII subjects ( 91 % ) and 50 MDI subjects ( 93 % ) completed the study . Mean A1C fell by 1.7 + /- 1.0 % in the CSII group to 6.6 % and by 1.6 + /- 1.2 % in the MDI group to 6.4 % . The difference in A1C between treatment groups was not statistically significant ( P = 0.20 ) . Eighty-one percent of CSII subjects and 90 % of MDI subjects experienced at least one episode of minor ( self-treated ) hypoglycemia ( P = 0.17 ) , and three CSII and six MDI 
    Output:
    
Interventions generally demonstrated improvement in HRQL .
Conclusions : A variety of interventions can improve HRQL  among adults with diabetes , but the magnitude of effects varied with the interventions .
