Increased rates of childhood obesity combined with more accessible information about the relationship between diet, physical activity and inactivity, and chronic diseases suggest the need for analyzing the complex process of receiving and transmitting messages related to child feeding practices. This study examined the perceptions of childhood obesity within 1 multiethnic community, the Commonwealth of the Northern Mariana Islands. In particular, through the use of focus groups, individuals indicated that sociocultural, familial, and official nutritional messages were most influential to their health care behaviors. The coordinated management of meaning (CMM) theory was used to gain insight into how individuals negotiate competing messages occurring at different levels of meaning. Given its focus on cultural influences (parallel to the concepts of archetypes), CMM proved especially relevant for understanding child feeding beliefs, values, attitudes, and practices in diverse ethnic populations. Implications for future health communication research that might draw from a CMM approach were identified, as well as pragmatic endeavors that focus on the development, implementation, and evaluation of culturally appropriate interventions in the prevention of childhood obesity. 相似文献

D-002 is a mixture of higher aliphatic primary alcohols isolated from beeswax, wherein triacontanol is the most abundant alcohol, with antioxidant and anti-ulcer properties. Since compounds with cytoprotective and antioxidant effects can improve healing of gastroduodenal ulcer induced by noxious agents, this work investigated the healing effect of D- 002 on acute and chronic gastric ulcers induced with indomethacin and acetic acid, respectively, in rats. Acute gastric ulcer was induced with single oral doses of indomethacin (20 mg/kg). Treatments with D-002 at 50, 100, and 200 mg/kg or vehicle were administered 3 hours after ulcer induction. Three hours later, rats were sacrificed, and the stomach was removed for quantifying the lesions. Chronic gastric ulcer was induced by 50 microL of 80% acetic acid application on the anterior serosal surface of the glandular stomach during 20 seconds. Twenty-four hours later D-002 at 50, 100, and 200 mg/kg or vehicle was administered for 5 days. At the end of the treatment, animals were fasted for 24 hours and sacrificed, the stomachs were removed, and the lesions were quantified. D-002 orally administered at 100 and 200 mg/kg acutely significantly healed gastric ulcers induced with indomethacin by 39% and 56% compared with positive controls, respectively. Also, D-002 at 200 mg/kg, but not at 50 or 100 mg/kg, administered orally for 5 days after ulcer induction exerted a significant healing effect (65.8% inhibition) in gastric ulcers induced with acetic acid. In conclusion, this work demonstrated that D-002 administered after ulcer induction induced effective healing of acute and chronic gastric ulcers provoked by, respectively, indomethacin and acetic acid. 相似文献

The aim of this study is to analyze the upper aerodigestive cancer survival in Umbria, a central Italian region, in the periods 1978-82 and 1994-98. The cases' data diagnosed in the period 1978-82 were derived from an ad hoc survey carried out in Umbria and for the years 1994-98 from Umbria Population-based Registry (RTUP). In the period 1994-98 the relative survival has lightly improved compared with the previous one. Comparison among five year relative standardized survival for head and neck, oesophagus and larynx, in Umbria region and in the other Italian registries, shows a quite high survival that could be further improved with an early diagnosis and, consequently, less destroying treatments. 相似文献

BACKGROUND: Current opinion in the medical literature concerning displaced supracondylar fractures of the distal humerus recommends pinning because with flexion braces there is a risk of both secondary displacement and Volkmann syndrome. PATIENTS AND METHODS: We analyzed 84 children with displaced supracondylar fractures. According to Rigault's classification, 30 children had grade 2 fractures, 21 had grade 3, 28 had grade 4 and 5 had multiple fragments, which were thus outside this classification. Fractures that could be reduced to a stable position under general anesthesia were treated with a posterior long arm splint with an average elbow flexion of 113 degrees (90-140). This technique was applied in 28 of the grade 2 fractures and in 4 of the grade 3 fractures, but in none of the grade 4 fractures. RESULTS: Of the 4 cases of Rigault grade 3 fractures treated nonoperatively, 3 had to be re-reduced and 1 needed an operation later on for varus correction. Of the 28 Rigault grade 2 fractures, 27 showed excellent results, and 1 had a good result. We advise nonoperative treatment in type 2 supracondylar fractures if stable reduction is achieved. 相似文献

A proficiency test on the quantification of Al, Cu, Mn, Se and Zn in serum was carried out to verify the performance of about 30 regional laboratories of the network of Italian laboratories. The exercise consisted of four runs in which the laboratories were free in choosing analytical methods to determine trace elements in freeze-dried animal serum. Laboratories performances were evaluated by the study of statistical functions as Coefficients of Variation (CV), Youden plot and Z-score value. As for Al, the results were generally characterized by good accuracy and precision, in spite of the low levels of the element (5-7 microg l(-1)). Copper determination had some problems only at low concentration (about 160 microg l(-1)--first run), in which an elevated number of anomalous data were found. Better data were achieved for Zn, for which anomalous values were mainly stragglers than outliers. Due to the low number of data for Mn (concentrations from 0.6 to 60 microg l(-1)) and Se (concentration from 45 to 106 microg l(-1)), a restricted statistical treatment was applied; for these elements high CV values were found (range from 30 to 80%). The results of this trial confirmed that participation in a proficiency test represents a benefit for all analytical laboratories. In fact, with few exceptions, most of the participants improved their performances in terms of Z-score values. 相似文献

Background: For some patients, especially those with a higher BMI, a non-selective Lap-Band? placement using the pars flaccida
approach with application of the small-diameter bands (9.75 and 10 cm) may be too tight or may require significant gastroesophageal
junction dissection and thinning. In such a case, the major perioperative complication is acute obstruction immediately after
surgery. We review the etiology of obstructive complications that present postoperatively in the first 24 hours. Case Reports:
Acute postoperative stoma obstruction (esophageal outlet stenosis) was observed in 5 patients who underwent 9.75-cm Lap-Band?
placement for morbid obesity. 2 of these patients had a postoperative upper GI series showing a misplaced band with gastric
slippage, and repeat operation was required. 3 patients had gastric obstruction without slippage. Of the latter, 1 patient
insisted that the band be removed rather than being replaced with a longer one, and the remaining 2 were managed with conservative
treatment, involving extended hospitalization until the edema subsided and the patient slowly regained the ability to swallow.
Conclusion: Obstructive symptoms associated with the Lap-Band? using the pars flaccida approach can be addressed conservatively
in most patients or by minimally invasive surgery; however we believe that routine use of the 11-cm Lap-Band? for the pars
flaccida approach could easily prevent this early complication. 相似文献

AIM: The aim of the present study was to evaluate the role of the preoperative antithyroid drug treatment and hormonal status in the development of early postoperative hypothyroidism after subtotal thyroidectomy in patients with Graves' disease. MATERIAL AND METHODS: Eighty-five patients with Graves' disease (males : females ratio 1:5.54, age range 19 to 64, 37.52 +/- 1.09 yrs) who had previously undergone surgical treatment were enrolled in the study. All patients underwent bilateral subtotal thyroidectomy with the amount of remnant tissue of 2-3 g for each lobe (total 4-6 g). Development of early (within one year after the operation) postoperative hypothyroidism was analyzed regarding the type of the antithyroid drug, preoperative dose, duration of the preoperative medical treatment, FT3, FT4, FT3/FT4 and hTSH. RESULTS: Forty six percent of all examined patients (54.12%) were euthyroid and 39 (45.88%/)--hypothyroid. Postoperative hypothyroidism was developed by 33.33% of the patients that had received preoperatively propylthiouracil compared with 50.82% of those treated with methymazol (p > 0.05). The duration of the preoperative treatment was 38.36 +/- 3.53 months for the hypothyroid patients and 30.11 +/- 2.34 months for the euthyroid patients (p < 0.05). Postoperative hypothyroidism developed in 58.70% of the patients with preoperatively suppressed thyroid-stimulating hormone (hTSH) and in 33.33% of those with normalized values of hTSH (p < 0.05). No statistically significant between-group difference was found in the preoperative dose of antithyroid agent, mean values of free triiodothyronine (FT3), free thyroxine (FT4), FT3/FT4, thyrotropic hormone (TSH). CONCLUSIONS: Longer preoperative antithyroid drug treatment and suppression of hTSH in the preoperative period correlated with higher risk of hypothyroidism after subtotal thyroidectomy. The type and the preoperative dose of the antithyroid agent, as well as the mean values of thyroid hormones before the operation have no prognostic significance for postoperative thyroid hypofunction. 相似文献

BACKGROUND: Vascular access thrombosis is an important cause of morbidity in patients with end-stage renal failure on maintenance hemodialysis (MHD). However, little is known about its risk factors. The present study was undertaken to evaluate the role of coagulation factors, fibrinolytic factors, and anti-phospholipid antibodies (aPL). In particular, we have evaluated the role of anti-protein C and anti-protein S antibodies in patients on MHD with and without thrombosis because no data are available in the literature. METHODS: The study group comprised 30 patients with thrombotic complications (TC), 40 patients matched for age, sex, and dialytic age with no thrombotic complications (NTC) and 400 controls. We have measured: anti-protein C antibodies, anti-protein S antibodies, anticardiolipin antibodies (ACA), anti-beta2-glycoprotein antibodies (beta2-GPI), and anti-prothrombin antibodies (aPT), along with prothrombin time, fibrinogen, plasminogen, protein C, protein S, anti-thrombin III, APC-resistance test, D-dimer, tissue-type plasminogen's activator, plasminogen activator inhibitor-1 (PAI-1), prothrombin fragment 1+2, factors of the intrinsic and extrinsic pathway, C-reactive protein, and homocysteine. RESULTS: There were no significant differences between groups for prothrombin time, fibrinogen, plasminogen, protein C, protein S, anti-thrombin III, activated protein C (APC) resistance, D-dimer, tPA, C-reactive protein, Factors II, X, and VII. The anti-beta2-GP1 and aPT were elevated in both TC and NTC patients, compared to the control group. Significant differences between TC and NTC groups were found for anti-protein C and anti-protein S antibodies, ACA-IgM, PAI-1, Factor VIII, prothrombin fragments 1+2, and homocysteine. CONCLUSION: The most novel finding was a significant elevation of anti-protein C antibodies and anti-protein S antibodies in the TC group (i.e., in patients on MHD with thrombosis of vascular access). It indicates that other pathogenetic mechanisms in addition to endothelial damage may cause hypercoagulability in uremia. 相似文献

Total hip or knee replacement patients who are overweight or obese often consider their disabling joint disease a cause for their increased weight. This prospective study investigated weight change in 100 patients after successful total joint replacement to determine whether surgical treatment of hip or knee arthritis leads to weight reduction. Postoperatively, both hip and knee replacement patients gained weight, with no difference in weight gain between hip and knee replacement patients. Younger hip patients gained a significant amount of weight. Patients a with normal body mass index and obese patients did not lose weight, while overweight patients gained a significant amount of weight after surgery. These findings demonstrate successful treatment of lower-extremity arthritis does not lead to weight loss, and obesity should be treated as an independent disease that is not the result of inactivity from arthritis. 相似文献
