Abstract
Background: The distribution of intestinal parasites among patients with tuberculosis in Ethiopia has not been well understood. Thus, this systematic review and meta-analysis was designed to determine the pooled national prevalence of intestinal parasites and its association with HIV among patients with tuberculosis in Ethiopia.
Methods: Original articles were searched in PubMed, Google Scholar, EMBASE, and World Health Organization’s HINARI portal and supplemented by the hand searching of cross-references. Data were extracted using a standard data extraction checklist. Random-effects model was used to estimate the pooled prevalence of intestinal parasites and odds ratio of the association. The I2 statistic was utilized to quantify statistical heterogeneity across studies. Funnel plot asymmetry and Egger’s regression tests were used to check for publication bias. The analysis was done by STATA version 14 for Windows.
Results: Of 725 identified studies, 12 articles were eligible for inclusion in the final analysis. The pooled national prevalence of intestinal parasites among patients with tuberculosis in Ethiopia was 36.1% (95% CI: 22.1 – 50.1, I2:98.7%). Subgroup analysis based on study design indicated that the prevalence of intestinal parasite among case-control studies was 41.69% (95% CI: 28.6 – 54.8, I2: 95.1%). The odds of intestinal parasites among patients with tuberculosis- HIV co-infection was not significantly different compared with patients with tuberculosis without HIV/AIDS (OR: 0.99, 95% CI: 0.7 - 4.7, p: 0.96).
Conclusion: In Ethiopia, at least one out of three patients with tuberculosis have intestinal parasite. These findings suggest the need of more attention on increasing screening tuberculosis patients for intestinal parasites and deworming intervention.

Authors: Aziz Kashif , Ahmad Habib 
Published: June 2019

Abstract
Background

Pulmonary nocardiosis is a rare disease. It usually affects immunocompromised patients. In this study we evaluated our clinical experience with pulmonary nocardiosis in our centre.

Method

It was a retrospective study done in Aga Khan University Hospital. Study was started after ethical approval. Cases from 2007 to 2017 were retrieved. Patient with diagnosis of Culture positive Pulmonary Nocardiosis with age more than 18 years included. Patient who were already on treatment of Nocardiosis at time of admission were excluded. Patients’ medical records were reviewed to identify epidemiologic, clinical, microbiologic, and radiographic features. Data was entered on SPSS V22.

Results

56 patient met inclusion criteria but 12 had missing data so 44 patients’ data was included at end. 8 patients had disseminated disease. 52% were immunocompromised and 48% were immunocompetent. 31 were females. Diabetes mellitus was most common comorbidity. Fever and shortness of breath were most common presentations. Pleural effusion and consolidation were most common chest xray findings. Mean white cell count was 12.35±7 ×109/L. 70% patient had some degree of hyponatremia. Culture showed that all strains were sensitive to amikacin and 67% were sensitive to imipenum. Mean length of stay was 7.7days. 30 day mortality was 23%. 16% required ICU stay. There was significant difference between immunocompromized and immunocompetent group regarding 30 day mortality (p value 0.019) and ICU admission need (p value 0.021).

Conclusion

Pulmonary nocardiosis is often missed, high index of suspicion is required especially in immunocompromised patients and mortality is often very high.

Abstract
Background

Glioma is one of the leading causes of death worldwide with high incidence, recurrence and mortality. IL-10 is a cytokine with dual function in many types of tumors. Although IL-10 is overexpressed and promotes tumor progression in human primary brain tumor, the mechanisms are largely unknown.

Methods

Glioma cells were treated with different dosages of IL-10. The cell growth was detected by CCK8, and the invasion was measured by Transwell. The relative expression of mRNAs was detected by Quantitative real-time PCR (q-PCR).

Results

We found that IL-10 treatment significantly enhanced glioma cell growth and invasion. And KPNA2 was significantly upregulated after treatment with IL-10. By performing knockdown experiments, we found that the glioma cell growth and invasion were significantly declined.

Conclusions

The results indicated that knockdown of KPNA2 significantly inhibited the growth and invasion of glioma cells. And IL-10 promotes glioma progression via upregulation of KPNA2. This study will be of important significance and provides a potential target for treatment of patients with glioma.

Abstract
Redox-sensitive trace elements and sulfur isotope compositions obtained via in situ analyses of sedimentary pyrites from marine black shales are used to track atmosphere-ocean redox conditions between ∼1730 and ∼1360 Ma in the McArthur Basin, northern Australia. Three black shale formations within the basin (Wollogorang Formation 1730 ± 3 Ma, Barney Creek Formation 1640 ± 3 Ma, and Upper Velkerri Formation 1361 ± 21 Ma) display systematic stratigraphic variations in pyrite trace-element compositions obtained using LA-ICP-MS. The concentrations of several trace elements and their ratios, such as Se, Zn, Se/Co, Ni/Co, Zn/Co, Mo/Co, Se/Bi, Zn/Bi, Ni/Bi, increase from the stratigraphically lower Wollogorang Formation to the Upper Velkerri Formation. Cobalt, Bi, Mo, Cu, and Tl show a consistent decrease in abundance while Ni, As, and Pb show no obvious trends.
We interpret these trace element trends as a response to the gradual increase of oxygen in the atmosphere-ocean system from ∼1730 to 1360 Ma. Elements more mobile during erosion under rising atmospheric oxygen show an increase up stratigraphy (e.g., Zn, Se), whereas elements that are less mobile show a decrease (e.g., Co, Bi). We also propose the increase of elemental ratios (Se/Co, Ni/Co, Zn/Co, Mo/Co, Ni/Bi, and Zn/Bi) up stratigraphy are strong indicators of atmospheric oxygenation.
Sulfur isotopic compositions of marine pyrite (δ34Spyrite) from these formations, obtained using SHRIMP-SI, are highly variable, with the Wollogorang Formation exhibiting less variation (δ34S = –29.4 to +9.5‰; mean –5.03‰) in comparison to the Barney Creek (δ34S = –13.8 to +41.8‰; mean +19.88‰) and Velkerri Formations (δ34S = –14.2 to +52.8‰; mean +26.9‰). We propose that the shift in mean δ34S to heavier values up-section corresponds to increasing deep water oxygenation from ∼1730 to 1360 Ma. Incursion of oxygenated waters possibly caused a decrease in the areal extent of anoxic areas, at the same time, creating a possibly efficient reducing system. A stronger reducing system caused the δ34S of the sedimentary pyrites to become progressively heavier. Interestingly, heavy δ34S in pyrites overlaps with the increase in the concentration of certain trace elements (and their ratios) in sedimentary pyrites (Se, Zn, Se/Co, Ni/Co, Zn/Co, Mo/Co, Ni/Bi, and Zn/Bi). This study concludes that there was a gradual increase of atmospheric oxygen accompanied by ocean oxygenation through the first ∼400 million years of the Boring Billion (1800–1400 Ma) in the McArthur Basin.

Published: June 2019

AbstractThe occurrence of minor elements in the structure of biogenic diatomaceous opal-A is an important issue because it is closely related to biogeochemical processes driven by the precipitation, sedimentation, and storage of diatoms, as well as to the properties and applications of diatomite, which is the sedimentary rock composed of diatomaceous opal-A. However, to date, there is no direct microscopic evidence for the existence of minor elements, such as Al, Fe, and Mg, in the structure of diatomaceous opal-A, because such evidence requires observation of the internal structure of frustules to exclude the disturbance of impurity minerals, which is technically challenging using conventional techniques. In this work, transmission electron microscopy (TEM) and scanning electron microscopy (SEM) combined with energy-dispersive X-ray spectroscopy (EDS) mapping analysis were performed on diatomaceous opal-A from three typical diatomite specimens that were pretreated using focused ion beam (FIB) thinning. This technique produces a slice of a diatom frustule for direct TEM observation of the internal structure of the diatomaceous opal-A. The results of this work clearly indicate that minor elements, such as Al, Fe, Ca, and Mg, conclusively exist within the siliceous framework of diatomaceous opal-A. The contents of these minor elements are at atomic ratio levels of 1 (minor element)/10 000 (Si) – 1/100, regardless of the genus of the diatoms. The occurrence of minor elements in the internal structure is likely through biological uptake during biosynthesis by living diatoms. Moreover, surface coatings composed of aluminosilicates on diatom frustules are common, and the contents of elements such as Al and Fe are tens or hundreds of times higher in the coatings than in the internal siliceous structure of diatomaceous opal-A. The discovery of the incorporation of the above-mentioned minor elements in the diatomaceous opal-A structure, both in the internal Si-O framework and on the surface, updates the knowledge about the properties of diatomite.

Published: June 2019

Abstract
Cholera remains a problem in sub-Saharan Africa, especially in Malawi. Our aim was to investigate drinking water source quality compared with water treatment, risk perception and cholera knowledge for patients who had reported to a health center for treatment in the 2017–2018 outbreak in Karonga District, Malawi. The study analyzed 120 drinking water samples linked to 236 cholera patients. Nearly 82% of the samples met the national criteria for thermotolerant coliforms of 50 cfu/100 ml, while 50% met the more stringent World Health Organization criteria of 0 cfu/100 ml. In terms of the human dimensions, 68% of survey respondents reported that they treated their water, while knowledge of prevention, transmission and treatment of cholera was also generally high. However, of the 32 patients whose drinking water sources had thermotolerant coliforms of 200+ cfu/100 ml, seven reported they felt a low or no personal risk for contracting cholera in the future and their community was extremely well prepared for another outbreak. The cost of a reactive response to cholera outbreaks puts a burden on Malawi, providing an opportunity for investment in innovative and localized preventive strategies to control and eliminate the risk of cholera while acknowledging social and cultural norms.

Published: June 2019

Objective: Sitagliptin phosphate and metformin hydrochloride tablet is an FDA approved combination product for the treatment of diabetes mellitus type 2. There are no reported evidence for estimation of undesired (S)-sitagliptin in a combination product. The objective of this study was to develop a high sensitive liquid chromatography method for the determination of (S)-enantiomer of sitagliptin phosphate in a fixed dose combination formula of metformin and sitagliptin.
Methods: The proposed novel high-performance liquid chromatography (HPLC) method uses programmed gradient elution of a mixture of ethanol-diethylamine(DEA) 100:0.1 (v/v) as mobile phase-A and a mixture of methanol-water 60:40 (v/v) as mobile phase-B. The chromatographic conditions were designed to nullify the metformin interference and in which sitagliptin enantiomers elute first and followed by metformin. A satisfactory resolution (≥2.5) between (S)-sitagliptin and active form (R)-sitagliptin was achieved with gradient elution on Chiralpak IA column (5μm, 4 × 250 mm) at a flow rate of 0.5 ml/min and the detector wavelength set at 265 nm. The injection volume set as 10 µl. The developed method has been validated as per the International Conference on Harmonisation (ICH) guidelines.
Results: The proposed HPLC method for determination of (S)-sitagliptin, showed good linearity in the concentration range of 0.5 µg/ml to 13.6 µg/ml and capable to quantify accurately up to the lowest level (LOQ) of 0.017%. The validated method was successfully applied to quantify the (S)-sitagliptin for different marketed formulations of sitagliptin with metformin and sitagliptin alone, and the corresponding recovery values were found to be in the range of 95.1% to 98.4%.
Conclusion: The proposed validated HPLC method was found to be suitable for the quantitative determination of (S)-sitagliptin in the formulations of sitagliptin with metformin and sitagliptin alone.

Objective: The present research work aims to evaluate the hypolipidemic activity of arogyavardhini and zpter tablet in high fat diet (HFD) induced hyperlipidemia in wistar rats.
Methods: Wistar rats were divided in 5 groups. The normal control group received standard pellet diet. The HFD group received HFD rich in cholesterol. The HFD+Arogyavardhini group received HFD rich in cholesterol along with Arogyavardhini treatment. The HFD+zpter group received HFD rich in cholesterol along with zpter treatment. The standard Control group received HFD rich in cholesterol and treatment with Atorvastatin. Serum Lipid profile estimation and histopathological estimations done at end treatment. Group means were compared with Analysis of Variance (ANOVA) followed by Tukey‘s post-hoc analysis (P<0.05).
Result: HFD group shows significant (P<0.05) increase in total cholesterol (TC) levels (207.15 mg/dl) and triglyceride (TG) levels (223.83 mg/dl) when compared with standard pellet fed rats (TC=151.05 mg/dl and TG=164.67 mg/dl). Treatment with Arogyavardhini significantly (P<0.05) reduces the increased levels of TC (160.123 mg/dl) and TG (189.5 mg/dl) in hyperlipedimic rats. Treatment with Zpter significantly (P<0.05) reduces the increased levels of TC (163.89 mg/dl) and TG (193.167 mg/dl) in hyperlipedimic rats, which is comparable to standard treatment atorvastatin (TC= 155.81 mg/dl, TG=180.33 mg/dl).
Conclusion: The observations in this study suggest that, herbal formulations arogyavardhini and zpter have the potential to overcome hyperlipidemia.

Published: June 2019

Objective: The primary objective of the project was to formulate and evaluate hard capsule containing the solution of ibuprofen. It also included enhancement of solubility of ibuprofen in hydrophilic solvents to obtain a unit dose capsule acceptable for human consumption.
Methods: Solution of ibuprofen was developed by the salt formation of partial drug using potassium hydroxide in PEG 600 and water. The solution was encapsulated in hard capsules with band sealing. The final formulation was evaluated for uniformity of weight, disintegration, drug content and stability. The dissolution profile was compared with that of available marketed tablets and softgels.
Results: The capsules were evaluated and found compliant as per specifications mentioned in general monograph of capsules in IP 2014. The uniformity of weight of the batch of capsules was found to be 734.8 mg (±0.58). The disintegration time of these capsules was observed to be 4.45 min. The drug content was found to be 100.03% and the product is stable over three months of test period under room temperature as well as accelerated conditions. The dissolution profile showed that softgels take longer time to release the drug whereas marketed tablets showed a dissolution profile comparable with that of formulated capsules.
Conclusion: The developed capsule is a unit dose of liquid containing solubilized ibuprofen delivering the drug directly into the gastrointestinal tract (GIT). These are newer solid oral dosage forms with higher patient compliance and ease in manufacturing. They require lesser steps and manufacturing area when compared to the manufacturing of compressed tablets.
Da conciliação trabalhista à resistência brizolista: o Partido Trabalhista Brasileiro (PTB) na região Oeste de Santa Catarina (1950-1965)
Authors: Silva Claiton Marcio da , Rigo Carla Aparecida 
Published: June 2019

O presente trabalho tem por objetivo analisar o surgimento da influência de Leonel de Moura Brizola na política de Chapecó/SC entre 1950 e 1965. Neste sentido, este artigo aborda o período compreendido entre o surgimento do Partido Trabalhista Brasileiro (PTB) e sua atuação conciliadora ao longo da década de 1950, até o crescimento da influência de Brizola em nível nacional enquanto um dos símbolos da resistência política através da “Campanha da Legalidade” e a criação do “Grupo dos Onze Companheiros”. A violência – física ou simbólica – é o fio condutor desta narrativa, argumentando como a história política local foi permeada pela perseguição aos grupos trabalhistas – também considerados “comunistas” por parte de grupos conservadores. Se em 1950 a influência conciliadora de Getúlio Vargas (pós-Estado Novo) ou de Alberto Pasqualini forneceu a linha do partido, ao final daquela década, uma nova geração de jovens na região Oeste de Santa Catarina adentrou na vida política tendo Brizola – e seus “admiráveis discursos”, que alcançavam a região através da rádio – como referência.
Guerra Fria: uma arqueologia do conceito (e sua atualidade) a partir do ocidente
Authors: Arraes Marcos Alexandre 
Published: June 2019

O presente artigo procura revisitar o conceito de Guerra Fria, partindo dos eventos que foram sua condição de possibilidade, para demonstrar os embates políticos e culturais que fundaram uma imagem consolidada do Ocidente em oposição a um outro inferior e ameaçador. Objetivo, assim, ao desvelar a alteridade aqui analisada, contribuir para a compreensão da história do tempo presente, especialmente da contemporaneidade da História do Brasil, onde opostos maniqueístas assentaramse de forma bastante evidente e perigosa. A relação temporal entre esses eventos, contudo, parece evidente e fica a cargo do próprio conceito de Guerra Fria e seus efeitos político-sociais.
