Earlier intervention in type 2 diabetes: the case for achieving early and sustained glycaemic control.

In type 2 diabetes, the onset and progression of complications is significantly delayed by improving glycaemic control. However, the proportion of patients reaching and sustaining guideline recommendations for glycaemic targets remains unacceptably low. Recent clinical trials and predictive physiologically based mathematical simulations (Archimedes model) indicate that benefits can be enhanced with earlier intervention and timely achievement of glycaemic targets. This article reviews the evidence for early intervention, showing that intensive approaches, including earlier introduction of combination therapy, allow more patients to achieve glycaemic targets and hence reduce complications and delay disease progression.

A comparison of the gastric emptying characteristics of selected sports drinks.

The purpose of this study was to determine the effects of repeated ingestion of drinks containing varying concentrations of carbohydrate on gastric emptying rate during steady-state exercise. On five separate occasions, 14 subjects cycled for 90 min at an average power output of 151 +/- 2 W. At 15-min intervals, subjects ingested 227 +/- 3 ml of either water, 4% carbohydrate (CHO), 6% CHO, or 8% CHO. Gastric volume was determined prior to each drink and at 90 min using the modified double-sampling technique. Gross gastric volumes were significantly greater and mean gastric emptying rates and the percentage of ingested beverage emptied from the stomach were significantly less for 8% CHO. These data indicate that repeated ingestion of an 8% CHO beverage during exercise significantly reduces gastric emptying rate, whereas lower concentrations of carbohydrate do not. In addition, beverage osmolality is not as important as beverage energy content in influencing gastric emptying rate at these carbohydrate concentrations.

Intestinal permeability in runners in the 1996 Chicago marathon.

Abdominal cramping, nausea, diarrhea, and GI bleeding are often reported in long-distance runners. This study set out to determine the effects of prolonged (2-4 hrs) exercise and NSAID ingestion on gastric and intestinal permeability during the first 5 hrs following the 1996 Chicago Marathon. Thirty-four healthy volunteers (20 M, 14 F; ages 30-50) completed the race and ingested the test solution (5 g sucrose, 5 g lactulose, 2 g rhamnose, in 40 ml water) within 10-15 min. The urinary excretion ratio of lactulose/rhamnose was used to assess small intestine permeability; sucrose excretion was used to evaluate gastric impairment. There were no significant differences for mean training mileage, postrace rectal temperature, and percent dehydration between runners who ingested NSAIDs and those who did not. In all, 75% of subjects reported aspirin or ibuprofen ingestion before or during the race. Runners who ingested ibuprofen had significant elevations in urinary lactulose excretion and lactulose/rhamnose ratio, whereas those who ingested aspirin or who did not ingest either NSAID had no significant differences in urinary excretion of lactulose, rhamnose, sucrose, or lactulose/rhamnose ratio compared to resting controls. Thirteen of the 26 NSAID users and 4 of the 8 non-users reported GI symptoms. It is concluded that (a) ibuprofen but not aspirin ingestion during prolonged exercise may increase gastrointestinal permeability and lead to GI symptoms, and (b) prolonged exercise alone can produce GI symptoms.

National cancer control programs and setting priorities.

Although considerable resources are being allocated globally to cancer research, efforts to implement these findings efficiently are lagging behind. Enough is known about the cause of common tumors such as lung, oral, and liver cancer to allow active measures to be taken for their prevention. Effective early detection programs have been developed for cervical, breast, and oral cancer, and treatment methods exist whereby at least one-third of all cancer patients can be cured if their disease is detected early. Unfortunately, however, most cancer activities currently in place were developed haphazardly and lack overall coordination. National cancer control efforts can be more effectively planned and implemented if they follow a systematic stepwise approach of assessing the current situation, setting health objectives, evaluating the possible strategies, and setting priorities using quantitative assessments. Cancer affects both developed and developing countries of the world, and well planned national efforts emphasizing prevention and early detection can significantly reduce the cancer problem.

Pulmonary carcinosarcoma and carcinoma: report of a case studied by electron microscopy, with critical review of the literature.

About 50 cases of pulmonary carcinosarcoma have been reported in the French and English literature. They have rarely coexisted with non-pulmonary neoplasms, never with other primary lung tumors. This report describes a 68 year old male smoker with a carcinosarcoma developing in the right upper lobe, one and a half years after a left upper lobectomy for a scar adenocarcinoma. By light microscopy, there was an admixture of adenocarcinomatous, chondrosarcomatous, and malignant spindle cell and giant cell areas. Electron microscopy showed well and poorly differentiated epithelial, smooth muscle and cartilaginous elements. This case is of interest because of its occurrence with another lung primary tumor; the specific diagnosis was made by transthoracic needle aspiration; and of the ultrastructural features. In the literature, carcinosarcomas have been divided into an endobronchial type, in which the carcinomatous component is squamous in 91% of cases, and a peripheral type, in which it is glandular in 50% of cases; the sarcomatous component shows no such correlation with type. The theories for the histogenesis of these tumors revolve around the concept that the carcinoma is the principal element, and the sarcomatous or stromal change secondary. Therefore, on the basis of this case, and of our literature review dealing with the pathology, clinical features and histogenesis of these tumors, we suggest that carcinosarcomas share important features with lung carcinomas.

Professional values in baccalaureate nursing education.

The purpose of this study was to compare program objectives of National League of Nursing-accredited baccalaureate programs with the professional nursing behaviors that reflect the seven values identified by the American Association of Colleges of Nursing (AACN). Findings showed that most of the professional behaviors were found in program objectives. However, behaviors reflective of two essential values, truth and esthetics, were identified only in a minority of program objectives. In addition, research and life-long learning were overwhelmingly identified in program objectives, but they were not reflected in the professional nursing behaviors of the AACN document. The professional nursing behaviors were also classified according to the three major roles of baccalaureate graduates. The provider-of-care role was dominant, followed by the member-of-profession and coordinator-of-care roles.

Alternatives for cardiac rehabilitation patients unable to return to a hospital-based program.

OBJECTIVE: To determine the effectiveness of a home exercise program using transtelephonic exercise monitoring (TEM). DESIGN: Prospective, two-group experimental, random assignment. SETTING: Urban centered hospital and surrounding community. SUBJECTS: Twenty cardiac rehabilitation patients entering a Phase II cardiac rehabilitation program. OUTCOME MEASURES: Maximal oxygen consumption, blood pressure, pressure-rate product, workload. INTERVENTION: Twenty male cardiac patients were randomly enrolled in either a 12-week home- or hospital-based exercise program. Maximal exercise tolerance tests were conducted, before and after exercise intervention, on a computer-driven bicycle ergometer. Subjects trained 3 days per week for 12 weeks on a bicycle ergometer for a maximum of 35 minutes at 75% of maximum heart rate reserve or functional capacity. RESULTS: Posttraining results showed significant improvement in cardiac function for both groups. Two patients in the TEM group developed new arrhythmias while exercising that required medication changes; however, no medical emergencies arose in either exercise group. Independent Student t test showed no significant difference between groups before or after training. CONCLUSIONS: We conclude that TEM is an effective alternative for the rehabilitation of patients who are unable to return to a hospital-based program.
