- Abstract
The objective of this study was to examine the cross-sectional convergent and known-group validity of the Malay-language EQ-5D-3L instrument in children and adults with transfusion-dependent thalassemia (TDT). A cross-sectional health-related quality of life survey involving TDT patients from 12 different treatment centers across Malaysia was conducted using the Malay PedsQL 4.0 Generic Core Scales and the Malay EQ-5D-3L questionnaire. Patients with non–TDT and other hemoglobinopathies were excluded. Convergent, discriminant, and known-group validity of the EQ-5D-3L was assessed against the PedsQL 4.0 Generic Core Scales in children. In the adult population, known-group validity of the EQ-5D-3L was assessed using an a priori hypothesis between patients' demographic characteristics and health outcomes obtained from literature. A total of 370 children and 225 adults were sampled. The mean (standard deviation) EQ-5D-3L scores of the children were 0.892 (0.082) and the adults were 0.887 (0.085). Convergent and discriminant validity was identified when correlated with the PedsQL domain in children. In both groups, known-group validity was evident when comparing groups of patients with reported problems to the group of patients with no reported problems on the EQ-5D-3L domains based on the a priori hypothesis derived from literature. This study found convergent, discriminant, and known-group validity of the Malay EQ-5D-3L in a population-based sample of patients with TDT. Hence, the instrument is valid for the assessment of health-related quality of life in children and adults with TDT in Malaysia. [ABSTRACT FROM AUTHOR]

- Abstract
Giardiasis, the infestation of the intestinal tract by Giardia lamblia , is one of the most prevalent parasitosis worldwide. Even though effective therapies exist for it, the problems associated with its use indicate that new therapeutic options are needed. It has been shown that disulfiram eradicates trophozoites in vitro and is effective in vivo in a murine model of giardiasis; disulfiram inactivation of carbamate kinase by chemical modification of an active site cysteine has been proposed as the drug mechanism of action. The triosephosphate isomerase from G. lamblia (GlTIM) has been proposed as a plausible target for the development of novel antigiardial pharmacotherapies, and chemical modification of its cysteine 222 (C222) by thiol-reactive compounds is evidenced to inactivate the enzyme. Since disulfiram is a cysteine modifying agent and GlTIM can be inactivated by modification of C222, in this work we tested the effect of disulfiram over the recombinant and trophozoite-endogenous GlTIM. The results show that disulfiram inactivates GlTIM by modification of its C222. The inactivation is species-specific since disulfiram does not affect the human homologue enzyme. Disulfiram inactivation induces only minor conformational changes in the enzyme, but substantially decreases its stability. Recombinant and endogenous GlTIM inactivates similarly, indicating that the recombinant protein resembles the natural enzyme. Disulfiram induces loss of trophozoites viability and inactivation of intracellular GlTIM at similar rates, suggesting that both processes may be related. It is plausible that the giardicidal effect of disulfiram involves the inactivation of more than a single enzyme, thus increasing its potential for repurposing it as an antigiardial drug.

- Abstract
• Hippeastrum escoipense is a potential source for the treatment of Chagas disease. • Candimine decreases the cytotoxic effect of benznidazole in mammalian cells. • Candimine induces alterations in the ultrastructure of T. cruzi. • The combination between candimine and benznidazole shows a synergistic effect in anti- T. cruzi assays. Chagas disease (CD), caused by Trypanosoma cruzi , represents a health threat to around 20 million people worldwide. Side effects of benznidazole (Bzn) cause 15–20% of patients to discontinue their treatment. Evidence has increased in favor of the use of drug combinations to improve the efficacy and tolerance of the treatment. Natural products are well known to provide structures that could serve as new drugs or scaffolds for CD treatment. Spp of the Amaryllidoideae sub family of Amaryllidaceae family are known by their bioactives alkaloids, which have been reported by their antiparasitic activities. To evaluate the anti- T. cruzi activity of the isolated alkaloid candimine (Cnd) from Hippeastrum escoipense Slanis & Huaylla; and to assess the combination effect between Cnd and Bzn against different life stages of T. cruzi parasites. The chemical profile of H. escoipense alkaloids extract (AE- H. escoipense), including quantitation of Cnd was performed through GC/MS and UPLC-MS/MS techniques. Subsequently, Cnd was isolated using Shephadex LH-20. Then, the AE- H. escoipense and Cnd were tested against T. cruzi , (epimastigotes, trypomastigotes, and amastigotes) by in vitro proliferation and viability assays. The cytotoxicity was evaluated against Vero and HepG2 mammalian cells. The ultrastructural analysis was perform by transmission electron microscopy (TEM) and mitochondrial activity was carried out by MTT assay. Drug combination assay between Cnd and Bzn was evaluated using the Chou-Talalay method. The AE- H. escoipense and Cnd showed high and specific anti- T. cruzi activity, comparable to Bzn. Cnd induces ultrastructural changes in T. cruzi , such as vacuolization, membrane blebs, and increased mitochondrial activity. Regarding the interaction between Cnd and Bzn, it generates synergism in the combinations of 0.25×IC 50 in epimastigotes, 2×IC 50 in trypomastigotes+amastigotes, and 0.25, 2, and 4×IC 50 in amastigotes. The synergism between Cnd and Bzn indicates that the combination at the concentration of 4×IC 50 could be useful as an effective new therapy against CD in the chronic stage. Thus, Cnd isolated from the leaves of H. escoipense emerges as potential candidate for the development of a new drug for the treatment of CD. [Display omitted] [ABSTRACT FROM AUTHOR]

Leishmaniasis is a neglected and endemic disease that affects poorest population mainly in developing countries. A lack of adequate and definitive chemotherapeutic agents to fight against this infection has led to the investigation of numerous compounds. The aim of this study was to investigate in vitro activity of boldine against Leishmania amazonensis murine cell infection. Boldine ((S)-2,9-dihydroxy-1,10-dimethoxy-aporphine) is an aporphine alkaloid found abundantly in the leaves/bark of boldo (Peumus boldus Molina), a widely distributed tree native to Chile. The in vitro system consisted of murine macrophage infection with amastigotes of L. amazonensis treated with different concentrations from 50 to 600 µg/ml of boldine for 24 hr. Intracellular parasite destruction was assessed by morphological examination and boldine cytotoxicity to macrophages was tested by the MTT viability assay. When cells were treated with 100 µg/ml of boldine the reduction of parasite infection was 81% compared with untreated cultures cells. Interestingly, boldine-treatment caused a concentration-dependent decrease of macrophage infection that culminated with 96% of reduction when cells were submitted to 600 µg/ml of boldine. Cell cultures exposed to 100 µg/ml of boldine and 300 µg/ml of Glucantime ® during 24 hr showed a significant reduction of 50% in parasitized cells compared with cell cultures exposed just to Glucantime®. The study showed that treatment with boldine produces a better effect than treatment with the reference antimonial drug, glucantime, in L. amazonensis infected macrophage. Our results suggest that boldine is a potentially useful agent for the treatment of leishmaniasis. [ABSTRACT FROM AUTHOR]

- Abstract
Mycetoma is a neglected tropical disease that commonly affects the lower extremity. The disease is attributed to subcutaneous granulomatous inflammation leading to distinct clinical features of gradual painless swelling accompanied by nodules and drains. Orbital mycetoma is an extremely rare entity of the disease. We reported the clinical presentation, diagnosis, and surgical outcomes in a case of orbital mycetoma with cranial extension. A 25-years-old male complained of left eye protrusion for 8 years, followed by complete loss of vision on the left eye for 7 years and eventually left eye pain for the last year. The left eye was displaced anteriorly and inferiorly with normal oculomotor, abducent, and trochlear examination. Brain CT scan showed an increase in orbital bone thickness with extension to the anterior cranial base, middle cranial base, and the orbital process of the zygomatic bone. MRI revealed a large lesion involving the left frontotemporal region with extension to left orbit, left posterior ethmoid air cells, and left temporal suprasellar region. The lesion was homogenously enhanced with contrast. The patient underwent a left orbitozygomatic cranitomy for resection of the lesion. However, total resection was inapplicable due to the extension of the bony lesion up to the petrous bone. Cranioplasty was performed by titanium mesh. Mycetoma is a chronic inflammatory disease affecting subcutaneous tissues commonly in the lower limbs. The disease can be caused by fungi (Eumycetoma) or bacteria (Actinomycetoma). Orbital mycetoma is an extremely rare entity of the disease. However, it is commonly associated with the cranial extension. Early diagnosis and prompt surgical and medical treatment are the keys to good outcomes. • Mycetoma is a chronic inflammatory disease affecting subcutaneous tissues commonly in the lower limbs. • The distinct clinical presentation includes painless swelling with nodules that produce drain secreted through sinus tracts. • Orbital mycetoma is an extremely rare entity of the disease. However, it is commonly associated with cranial extension. • Early diagnosis and prompt surgical and medical treatment are the keys to good outcomes [ABSTRACT FROM AUTHOR]
