Black communities face multiple stressors including racism, discrimination, and navigating systems of oppression, all of which affect their mental health and wellbeing. In recent years, the practice of self-care has gained popularity as a strategy to cope with stress and to improve overall health. However, the current discourse often focuses on individual self-care behaviors and excludes systemic and community level factors that encourage, sustain, or inhibit self-care practices. This paper contextualizes a conceptual model of self-care with intersectionality theory and the psychology of liberation framework, in relation to the lived experiences of Black communities. The paper aims to underscore the necessity of self and community care as a tool for social justice, preservation, and resistance against oppressive systems that threaten the mental health and wellness of this community.
We have studied the evolution of the gamma interferon (IFN-γ) and interleukin 10 (IL-10) responses after Mycobacterium ulcerans sonicate stimulation of whole blood from patients with early M. ulcerans lesions during treatment with rifampin and streptomycin for 8 weeks. Among the 26 patients, secretion of IFN-γ increased during treatment, with a significant increase at 4 weeks and a further increase after 8 weeks overall. The increase was more rapid in patients with large or ulcerative lesions, becoming significant by 4 weeks. For small lesions, there was only a minor increase, which did not reach significance. There was no significant change in the median IL-10 response during antibiotic therapy, and there was no inverse correlation between IFN-γ and IL-10 responses. These results demonstrate that an IFN-γ secretory response to M. ulcerans developed, independently of IL-10 secretion, in patients whose M. ulcerans disease healed during antibiotic therapy. 相似文献
The prevalence of heart failure (HF), including reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF), has increased significantly worldwide. However, the prognosis and treatment of HF are still not good. Recent studies have demonstrated that high-density lipoprotein (HDL) plays an important role in cardiac repair during HF. The exact role and mechanism of HDL in the regulation of HF remain unexplained. Here, we discuss recent findings regarding HDL in the progression of HF, such as the regulation of excitation-contraction coupling, energy homeostasis, inflammation, neurohormone activation, and microvascular dysfunction. The effects of HDL on the regulation of cardiac-related cells, such as endothelial cells (ECs), cardiomyocytes (CMs), and on cardiac resident immune cell dysfunction in HF are also explained. An in-depth understanding of HDL function in the heart may provide new strategies for the prevention and treatment of HF.
This study was carried out to investigate the cardiovascular effect of administration of antimalarial drugs amodiaquine and artesunate and the efficacy of Garcinia kola extract (kolaviron) in protecting against such possible effect. Thirty (30) adult male albino rats divided into six (6) groups were used in this study. Groups D, E and F were treated with 100 mg/Kg b. w of the extract twice daily for the first one week and 200 mg/Kg b. w. /day for the subsequent three (3) weeks. Amodiaquine (10mg/Kg. b. w. /day) was administered orally for four (4) days into rats in groups A and E while rats in groups B and F were treated with artesunate (5mg/Kg b. w. /day) for four (4) days. Group C rats (normal control) were treated with normal saline. All the rats were sacrificed after four (4) weeks treatment period. Blood was withdrawn by cardiac puncture while the liver, kidney, stomach and heart were removed, cleansed and weigh. Total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides were measured in the serum, while total fibrinogen, platelet count, red blood cell and white blood cell count were measured in the whole blood. The artherogenic and coronary risk index were also determined. Results indicate that both amodiaquine and artesunate predispose to cardiovascular disease, however the effect was more pronounced with artesunate than amodiaquine. The result also suggests that both drugs could increase the risk of coronary and artherogenic diseases and that Garcinia kola do not prevent the cardiotoxicity and coronary risk effect. 相似文献
BACKGROUND: It is a common opinion that expansion and darkening in melanocytic nevi may occur during pregnancy. The main problem is that whether it is a usual finding, or it is a condition that requires suspicion about melanoma. OBJECTIVES: It was aimed to find the changes that might occur in the sizes and structures of melanocytic nevi during pregnancy. METHODS: Ninety-seven nevi of the 56 pregnant women in the first trimester were evaluated in the study. The localization and size of the nevi were recorded on a standard body diagram. After clinical examination, dermoscopic analyses were applied. Pattern analyses were done, and total dermoscopy scores (TDS) were calculated by applying ABCD scoring system. All subjects were seen again during the third trimester. RESULTS: There was a statistically significant difference between the mean diameters of nevi in the first and third trimester (P = 0.001). Of nevi whose diameters increased, 10 (50.00%) were localized on the front of body, 6 (30.00%) on the face and neck, 3 (15.00%) on the legs, and 1 (5.00%) on the back. The enlargement in diameters was more significant on the front of the body, but there was no statistically significant difference. Compared according to the pattern analysis, new dot formation was observed only on the structure of six nevi during the last trimester. Four of them were localized on the front of the body. There was statistically significant increase in mean TDS in comparison between the first and third trimesters (P = 0008). CONCLUSIONS: During the pregnancy, widening in diameters and structure changes of nevi may be seen especially on the front of the body. We also think that these findings might be connected with expansion of the skin during pregnancy. Dermoscopic controls are the first choice of method to analyse the nevi since the patient may not recognize these changes. 相似文献
The reliability and validity of the earlier developed Buruli ulcer functional limitation score (BUFLS) questionnaire was assessed. Of 638 former Buruli ulcer patients (of 678 individuals examined), sufficient items on daily activities (>or= 13 of the 19) were applicable to calculate a score. To determine the validity, the functional limitation scores of the 638 individuals were compared with the global impression of the limitations, range of motion (ROM), and the social impact (change of occupation or education) of Buruli ulcer. To determine inter-observer reliability, the functional limitation score was reassessed in 107 participants within one and three weeks after the first interview by another interviewer and interpreter. Both global impression and ROM correlated well with the functional limitation scores (rho = 0.66 and rho = 0.61). The inter-observer reliability of 107 participants as measured by an intra-class correlation coefficient of 0.86 was very good. The functional limitation scores measured in the second assessment were significantly higher than in the first assessment. This should be taken into account when the functional limitation score is used for the individual patient. The BUFLS can be used as for between group comparisons of endpoints in clinical trials and in the planning of resources. 相似文献
Gaucher disease is a heterogeneous disease characterized by impaired
activity of the lysosomal enzyme glucocerebrosidase. This heterogeneity is
attributed to a large number of mutations in the corresponding gene. In
order to test the biochemical properties of some mutations prevalent among
Israeli populations, the normal human glucocerebrosidase cDNA and cDNAs
carrying mutations N370S, L444P, D409H, recTL, recNcil, P415R and 84GG were
coupled to the T7 RNA polymerase promoter in a vaccinia virus- derived
expression vector (pTM-1). Recombinant viruses were produced and used to
infect human tissue culture cells. RNA and protein stability, recognition
by anti-glucocerebrosidase monoclonal antibodies and intracellular
enzymatic activity were measured. The results demonstrated that the D409H
allele directed synthesis of cytoplasmic RNA with decreased stability
compared with its normal counterpart or other mutated forms. The D409H and
L444P mutated proteins had lower stability than that of their normal
counterpart, while the recNcil- mutated protein was more stable. Only
glucocerebrosidase forms harboring leucine at position 444 were recognized
by the anti- glucocerebrosidase monoclonal antibodies used (8E4 and 2C7).
Measurements of enzymatic activity of the recombinant proteins in cells
loaded with a fluorescent glucosylceramide demonstrated that the N370S
mutated enzyme had activity similar to that of the normal enzyme. The other
mutated enzymes exhibited varying degrees of activities, generally
corresponding to the phenotypes with which they are associated. The results
presented demonstrate the use of the vaccinia virus-derived expression
system and of loading living cells with fluorescent substrate as efficient
tools for studying mutants in Gaucher disease and in other lysosomal
diseases.
