Clinical Characteristics, Medication Prescription Pattern, and Treatment Outcomes at the Neonatal Intensive Care Unit of a Tertiary Health Care Facility in Ghana

Objective: Neonates are more susceptible to infections, as well as medication toxicities. This study, therefore, sought to describe the clinical characteristics, medication prescription pattern, and treatment outcomes for neonates admitted to the neonatal intensive care unit (NICU) of a tertiary health-care facility in Ghana. Methods: A retrospective cross-sectional study was conducted to ascertain clinical records, conditions for admission, spectrum of medications prescribed, and treatment o...

Antiplasmodial prenylated flavanonols from Tephrosia subtriflora

Abstract The CH2Cl2/MeOH (1:1) extract of the aerial parts of Tephrosia subtriflora afforded a new flavanonol, named subtriflavanonol (1), along with the known flavanone spinoflavanone B, and the known flavanonols MS-II (2) and mundulinol. The structures were elucidated by the use of NMR spectroscopy and mass spectrometry. The absolute configuration of the flavanonols was determined based on quantum chemical ECD calculations. In the antiplasmodial assay, compound 2 showed the highest activit...

In vitro and in vivo antiplasmodial activity of extracts of selected Kenyan medicinal plants

Abstract Malaria is one of the most important parasitic diseases in the world. It remains a major public health problem in Africa and is responsible for the annual death of over one million children below the age of five years. The Plasmodium falciparum is the most widespread etiological agent for human malaria and has become increasingly resistant to standard antimalarial drugs. Therefore, this necessitates a continuous effort to search for new drugs, particularly with novel modes of action...

Phytochemical, Cytotoxicity, and Antimycobacterial Activity Evaluation of Extracts and Compounds from the Stem Bark of Albizia coriaria Welw ex. Oliver

Abstract ackground. Albizia coriaria Welw ex. Oliver (Fabaceae) is one of the plants used by herbalists in the East Africa community to prepare herbal remedies for the management of symptoms of TB. Despite its widespread use, the antimycobacterial activity of this plant was uninvestigated and there was contradicting information regarding its cytotoxicity. Methods. Cytotoxicity (MTT), antimycobacterial activity (MABA), and phytochemical screening were conducted on crude extracts (hexane, chlo...

Sub-Acute Toxicity Effects of Methanolic Stem Bark Extract of Entada abyssinica on Biochemical, Haematological and Histopathological Parameters in Wistar Albino Rats

Abstract Background: Whereas the efficacy of Entada abyssinica (fabaceae) extracts against various ailments has been scientifically validated, its safety has not been established. This study was undertaken to evaluate the toxicity effects of methanolic stem bark extract of E. abyssinica on biochemical, haematological and histological parameters of Wistar albino rats following repeated oral administration. Methods: Wistar albino rats of both sexes were randomized into groups and orally admini...

Traditional Medicinal Uses, Phytoconstituents, Bioactivities, and Toxicities of Erythrina abyssinica Lam. ex DC. (Fabaceae): A Systematic Review

Abstract Background. Many studies have been undertaken on the medicinal values of Erythrina abyssinica Lam. ex DC. (Fabaceae). The details, however, are highly fragmented in different journals, libraries, and other publication media. This study was therefore conducted to provide a comprehensive report on its ethnobotany, ethnomedicinal uses, phytochemicals, and the available pharmacological evidence supporting its efficacy and safety in traditional medicine. Method. We collected data using a...

A Randomized Trial to Monitor the Efficacy and Effectiveness by QT-NASBA of Artemether-lumefantrine versus Dihydroartemisinin-piperaquine for Treatment and Transmission Control of Uncomplicat

Abstract: Background: Many countries have implemented artemisinin-based combination therapy (ACT) for the first-line treatment of malaria. Although many studies have been performed on efficacy and tolerability of the combination arthemeter-lumefantrine (AL) or dihydroartemisinin-piperaquine (DP), less is known of the effect of these drugs on gametocyte development, which is an important issue in malaria control. Methods and results: In this two-arm randomized controlled trial, 146 children ...

Efficacy of Single-Dose Primaquine With Artemisinin Combination Therapy on Plasmodium falciparum Gametocytes and Transmission: An Individual Patient Meta-Analysis

Abstract: Background. Since the World Health Organization recommended single low-dose (0.25 mg/kg) primaquine (PQ) in combination with artemisinin-based combination therapies (ACTs) in areas of low transmission or artemisinin-resistant Plasmodium falciparum, several single-site studies have been conducted to assess efficacy. Methods. An individual patient meta-analysis to assess gametocytocidal and transmission-blocking efficacy of PQ in combination with different ACTs was conducted. Random ...

The effects of crude propolis, its volatiles andethanolic extracts on the ecto-parasitic mite,Varroa destructorand health of the Africansavannah honey bee,Apis mellifera scutellata

Abstract: Propolis is a hive product composed of biologically active plant resins, and has been shown toenhance individual honey bee (Apis melliferaL.) health. Propolis has also been demonstratedto mitigate, in part, the negative effects caused by the ecto-parasitic miteVarroa destructorand its associated viruses on the health of managed European honey bee colonies.However, its effect on the health status of African honey bees remains largely unknown.Here, we found that the African savannah ...

PHARMACOGNOSTIC INVESTIGATION, ISOLATION, CHARACTERIZATION AND CONFIRMATION OF THE STRUCTURE OF PHENACETINE EXTRACTED FROM THE DRIED POWDERED LEAVES OF TRADITIONAL MEDICINAL PLANT ALLOPHYLUS

Abstract Pharmacognostic investigation involving organoleptic evaluation, fluorescent analysis, phytochemical screening and mineral analysis was carried out on the dried powdered leaves of Allophylus africanus used for treating pain, headaches, common cold, Fever and as antibiotics in Eastern Province of Sierra Leone. The powdered leaves were light brown in colour with woody odour, bitter taste and gave significant fluorescent derivatives with the reagents 1M NaOH (aq), 1M NaOH(alc.), Ammonia...

PHYTOCHEMICAL SCREENING AND IN VIVO ANTIMALARIAL ACTIVITY OF THE METHANOL LEAF EXTRACT OF TAPINANTHUS DODONEIFOLIUS (DC) DANSER GROWING ON VITEX DONIANA

Malaria is a major public health problem in the world especially in Africa, with an estimated two million  children and pregnant women worldwide dying of malaria yearly, primarily because of Plasmodium  falciparum and its complications. Preliminary phytochemical screening of the methanol leaf extract revealed the presence of triterpenoids, saponins, tannins, terpenoids, flavonoid, cardiac glycoside,  carbohydrate and alkaloids. The in vivo antimalarial activity of the crude methanol leaf ...

Evidence for the Immune Toxicity of Green Tea Polyphenols: A Computational Study

Adverse drug reactions (ADR) triggered by a drug or its metabolites is an essential aspect of the post-clinical phase in the drug discovery pipeline. The pathophysiology of ADRs has been described in two ways; expected and idiosyncratic. In the current study, we deployed valid computational tools to predict the ability of eight green tea polyphenols to favourably interact with HLA-B*57:01 and mediate idiosyncratic ADRs. First, we deployed molecular docking to understand the free energy profil...
