Efficacy and Feasibility of Allogeneic Hematopoietic Stem-Cell Transplantation in the Treatment of Refractory Acute Myeloid Leukemia

Background

Refractory acute myeloid leukemia (AML) includes AML includes failure of disease to respond to standard induction chemotherapy, relapse within 6 months after first CR, and 2 or more relapses. The outcome of these patients is usually very poor; only a small proportion can be rescued by allogenic hematopoietic stem-cell transplantation (allo-HSCT). The aim of this study was to evaluate the efficacy and feasibility of allo-HSCT in patients with refractory AML.

Comparison of the protective effects of curcumin and caffeic acid phenethyl ester against doxorubicin-induced testicular toxicity

Whether testicular toxicity is mediated by matrix metalloproteinases (MMPs) is an important question that has not been examined. This study investigated the suppressive effect of curcumin and caffeic acid phenethyl ester (CAPE) on oxidative stress, apoptosis, and whether MMPs mediate doxorubicin (DOX)-induced testicular injury. Male rats were randomly divided into eight groups (n = 8 per group). The groups were as follows: sham, dimethyl sulphoxide (100 µL), DOX (3 mg/kg), CAPE (2.68 mg/kg), curcumin (30 mg/kg), DOX+CAPE (3 mg/kg DOX and 2.68 mg/kg CAPE), DOX+curcumin (3 mg/kg DOX and 30 mg/kg curcumin) and DOX+CAPE+curcumin (3 mg/kg DOX, 2.68 mg/kg CAPE and 30 mg/kg curcumin). Injections were administered daily for 21 days. The oxidative stress, MMPs, proinflammatory cytokines and apoptotic markers in the DOX group were higher than the sham group (p < .05); these measures were lower in the groups treated with CAPE and curcumin together with DOX compared with the DOX group (p < .05). The results showed that MMPs mediated DOX-induced testicular injury, but CAPE and especially curcumin suppressed testis injury and cell apoptosis by suppressing DOX-induced increases in MMPs, oxidative stress and proinflammatory cytokines. However, curcumin exhibited more pronounced effects than CAPE in terms of all studied parameters.     

People don’t live on the care cascade: The life of the HIV care cascade as an international AIDS policy and its implications

ABSTRACT

This article analyses how the HIV care cascade, an analytical tool, has become a policy practice that determines the direction and content of international AIDS policy. It traces the development of the cascade through from its emergence around 2011 to its position framing global AIDS policy by 2018. The article distinguishes between the cascade model as a mapping tool and the care cascade as a policy that aims to end the AIDS epidemic. It then argues that the move from an analytical to a policy tool has important implications, both for the scope of policies and for policy-relevant research. It concludes by considering its implications in determining policy direction. The qualitative research that informs the article is based on published care cascade research and policy documents, and observations of the presentations and discussions at the 2012 and 2018 International AIDS Conferences (IAS). The article uses textual analysis to develop its argument.     

Diurnal Alterations of Refraction,Anterior Segment Biometrics,and Intraocular Pressure in Long-Time Dehydration due to Religious Fasting

Purpose: To investigate the effects of dehydration due to fasting on diurnal changes of intraocular pressure, anterior segment biometrics, and refraction. Subjects and methods: The intraocular pressures, anterior segment biometrics (axial length: AL; Central corneal thickness: CCT; Lens thickness: LT; Anterior chamber depth: ACD), and refractive measurements of 30 eyes of 15 fasting healthy male volunteers were recorded at 8:00 in the morning and 17:00 in the evening in the Ramadan of 2013 and two months later. The results were compared and the statistical analyses were performed using the Rstudio software version 0.98.501. The variables were investigated using visual (histograms, probability plots) and analytical methods (Kolmogorov-Smirnov/Shapiro-Wilk test) to determine whether or not they were normally distributed. Results: The refractive values remained stable in the fasting as well as in the control period (p?=?0.384). The axial length measured slightly shorter in the fasting period (p?=?0.001). The corneal thickness presented a diurnal variation, in which the cornea measured thinner in the evening. The difference between the fasting and control period was not statistically significant (p?=?0.359). The major differences were observed in the anterior chamber depth and IOP. The ACD was shallower in the evening during the fasting period, where it was deeper in the control period. The diurnal IOP difference was greater in the fasting period than the control period. Both were statistically significant (p?=?0.001). The LT remained unchanged in both periods. Conclusions: The major difference was shown in the anterior chamber shallowing in the evening hours and IOP. Our study contributes the hypothesis that the posterior segment of the eye is more responsible for the axial length alterations and normovolemia has a more dominant influence on diurnal IOP changes.     

Relationship of neutrophil gelatinase-associated lipocalin (NGAL) and procalcitonin levels with the presence and severity of the preeclampsia

Objective: The aim of the present study was to evaluate changes in maternal serum neutrophil gelatinase-associated lipocalin (NGAL) and procalcitonin (PCT) concentrations in preeclampsia.

Material and method: This case–control study consisted of 40 preeclamptic and 40 healthy singleton pregnancies matched for age and body mass index. Serum NGAL and PCT levels were compared between the groups. Diagnostic performance and clinical association of these markers were evaluated.

Results: NGAL and PCT concentrations were significantly higher in preeclamptic group (p?p?=?0.001, respectively) and their levels were correlated with the severity of the preeclampsia. There were significant positive correlation between these markers and mean arterial pressure (MAP) and spot urine protein excretion. There was negative correlation between NGAL and apgar scores and fetal birth weight. Pregnancies with higher NGAL (OR: 4.89; 95% CI: 1.81–13.21) and higher PCT (OR: 6.67; 95% CI: 2.44–18.21) concentrations had higher risk for preeclampsia.

Conclusion: NGAL and PCT may be potential biomarkers for preeclampsia. Their levels increase significantly in preeclampsia and they are related to the severity of the disease. These results are in agreement with the generalized endothelial damage and persistant inflammatory status in preeclampsia. NGAL may also be an indicator for adverse neonatal outcomes with decreased placental hypoperfusion.
