People who use drugs are continuously subjected to harsh stigmatization through a process of relational and social degradation, which limits their possibility for recovery. This quantitative study explores the perspectives of family members or significant others of illicit drug users, regarding general beliefs about illicit drug use and their stigma. Respondents agree that most people do not trust people who use drugs, disregard individuals who have been hospitalized due to drug problems and do not think people who use drugs are as intelligent as the general population. These findings reveal a high level of public stigma regarding illicit drug use. 相似文献
Ageing is associated with changes in body composition that may result in sarcopenic obesity (SO). Interleukin-6 (IL-6) and C-reactive protein (CRP) are important inflammatory markers related to ageing. SO has been examined as an important public health problem, but its association with inflammatory markers has yet to be investigated. The aim of this study was to investigate the association between SO-related phenotypes and inflammatory markers in postmenopausal women. A total of 130 women (66·7 ± 5·2 years) underwent body composition evaluation using dual-energy X-ray absorptiometry. Volunteers were classified according to a SO definition previously described in the literature. Waist circumference (WC) and handgrip strength (HG) were also measured. Blood samples were collected for CRP, tumour necrosis factor and IL-6 measurements. All the inflammatory markers were higher in SO individuals when compared to non-SO; however, only IL-6 reached statistical significance (median 3·34 versus 1·37 pg ml−1; P<0·05). Also, CRP was significantly correlated (P<0·01) with body mass index (rs = 0·34), fat mass (FM; rs = 0·25) and WC (rs = 0·33). Similarly, IL-6 levels were significantly correlated (P<0·05) to age (rs = 0·19), FM (rs = 0·19) and WC (rs = 0·17). HG was found to be significantly reduced among subjects with higher IL-6 levels (P =0·02). In summary, the combination of reduced muscle mass and excess body fat (i.e. SO) is associated with elevated inflammatory markers in postmenopausal women. Moreover, CRP and IL-6 are associated with SO-related phenotypes in this population. 相似文献
Background: Patients with diabetes mellitus who undergo coronary stenting are at increased risk of restenosis. It is known that inflammation plays a crucial role in restenosis. Objective: We assessed the inflammatory response to elective coronary stent implantation (CSI) in stable diabetic and nondiabetic patients. Methods: C‐reactive protein (CRP), soluble (s) P‐selectin, and soluble intercellular adhesion molecule (sICAM)‐1 plasma levels were determined in diabetic (n = 51) and nondiabetic (n = 56) patients before and 48 hours and 4 weeks after bare metal stenting (BMS). Results: Diabetic patients presented significantly higher inflammatory marker levels before and after CSI. Nonetheless, diabetic and nondiabetic patients had postintervention peak of markers attained within 48 hours. At baseline, diabetic and nondiabetic patients presented CRP levels of 5.0 ± 20.1 (P ≤ 0.04) and 3.8 ± 9.4 μg/ml and, at 48 hours postintervention, 22.0 ± 20.2 (P = 0.001; P = 0.002) and 12.6 ± 11.3 (P ≤ 0.0001) μg/ml. Regarding sP‐selectin, diabetic and nondiabetic patients obtained levels of, at baseline, 182 ± 118 (P ≤ 0.04) and 105 ± 48 ng/ml and, at 48 hours, 455 ± 290 (P = 0.001; P ≤ 0.01) and 215 ± 120 (P ≤ 0.04) ng/ml. For diabetic and nondiabetic patients, sICAM‐1 levels were, at baseline, 248 ± 98 (P ≤ 0.04) and 199 ± 94 ng/ml and, at 48 hours, 601 ± 201 (P = 0.001; P ≤ 0.01) and 283 ± 220 (P = 0.001) ng/ml. At 4 weeks, for all patients, markers returned to preprocedural levels: versus before PCI: *P = 0.001, §P ≤ 0.0001; versus nondiabetic patients: #P ≤ 0.04, ¶P = 0.002, ?P ≤ 0.01. Conclusions: Diabetic and nondiabetic patients exhibited a temporal inflammatory response after an elective BMS. However, diabetic patients present higher preprocedural levels of CRP, sP‐selectin, and sICAM‐1 and reveal a further exacerbated inflammatory response after intervention. The differences in inflammatory response may have implications in restenosis within these two sets of patients.相似文献

This study evaluated, for the first time, the genetic diversity of Toxoplasma gondii isolates from free-range chickens from the state of Paraíba, Northeast Brazil. Tissue samples from 33 chickens from properties in five municipalities of Paraíba (Esperança, Olho d’Água, Malta, Monteiro, and Patos) were bioassayed in mice. The brains of mice infected with T. gondii cysts were used for DNA extraction and genotyping. Genotyping was performed using 11 PCR-RFLP markers and 15 microsatellite (MS) markers. Complete genotyping results were obtained for 29 isolates, with nine genotypes detected by RFLP and 15 genotypes identified by MS. Three genotypes (#273, #274, and #277) have only been recently identified from pigs in the region. Brazilian clonal types BrII and BrIII were identified from one isolate each. Clonal types I, II, and III were not detected by RFLP. Genotype #13 (Caribbean 1), detected in 48.3% (14/29) of isolates from four of the five municipalities investigated, was the most prevalent genotype in the state of Paraíba. However, the MS analysis showed that of these 14 isolates, only four were unique genotypes, and considering the distance between the municipalities from where they were collected, it is possible that only seven are independent isolates while the others are clones. The other genotypes were restricted to different microregions. The results indicate that the Caribbean 1 lineage of T. gondii is circulating widely in Northeast Brazil. The genotypic diversity of T. gondii in the state of Paraíba is high, and microsatellite analysis revealed this diversity with higher resolution than PCR-RFLP.
