Pneumococcal disease in children in the Middle East and Northern Africa: A systematic literature review of clinical burden, serotype distribution, and vaccination programs.

Bacterial diseases caused by are an important public health problem in Middle Eastern and North African countries. The burden of is poorly documented in these regions, local surveillance programs are lacking. This systematic review was conducted in Medline and Embase to obtain a comprehensive overview of the clinical burden of pneumococcal disease and pneumococcal vaccination status in the pediatric population in Middle East and Northern Africa.

The indirect costs of vaccine-preventable cancer mortality in the Middle East and North Africa (MENA).

Background: Infections are responsible for ∼13% of cancer cases worldwide, with human papillomavirus (HPV) and hepatitis B (HBV) among the infections associated with cancer for which vaccines are available. The aim of this study was to estimate the indirect cost of premature mortality related to cancers caused by HPV and HBV in Middle East and North Africa (MENA) countries.

Methods: The number of deaths and years of life lost (YLL) in 2019 from four HPV-related cancers: cervical cancer, oral cavity cancer, laryngeal cancer, and oropharynx cancer, as well as HBV-related liver cancer were sourced from the Institute for Health Metrics Evaluation (IHME) Global Burden of Disease database.

Economic evaluation of doravirine/tenofovir disoproxil fumarate/lamivudine for HIV-1-infected adults in Russia: a cost-minimization and budget impact analysis.

Background: In Russia, before 2022, the list of vital and essential drugs for HIV-infected patients previously untreated with antiretroviral drugs included the fixed-dose combination rilpivirine/tenofovir disoproxil fumarate/emtricitabine (RPV/TDF/FTC) but not doravirine/tenofovir disoproxil fumarate/lamivudine (DOR/TDF/3TC).

Methods: An indirect comparison of the efficacy of DOR/TDF/3TC and RPV/TDF/FTC defined by virologic suppression (HIV-1 RNA of <50 copies/mL at week 48) was made. The per-patient drug costs over 1 year were compared in a cost-minimization analysis.

Concept of Combining Cost-Effectiveness Analysis and Budget Impact Analysis in Health Care Decision-Making.

Objectives: The objective of this study is to cover the ways of solving the problem of understanding the results of two key methods of pharmacoeconomic analysis - budget impact and cost-effectiveness. It is important to note that pharmacoeconomic assessment based on this evidence often has controversial character. The results of one type of analysis can characterize assessed health technology favorably, and the results of other critically.

Absorption, distribution, and transformation of TNT in higher plants.

The ability of eight species of plants to assimilate 2,4,6-trinitrotoluene (TNT) was investigated. Glycine max (soybean), in particular, demonstrated rapid assimilation of high concentrations of this explosive. Penetration and localization of [1-(14)C]-TNT in plant root cells and leaves were studied via electron microscopic autoradiography.

Degradation of aromatic compounds in plants grown under aseptic conditions.

The aim of the work is to investigate the ability of higher plants to absorb and detoxify environmental pollutants - aromatic compounds via aromatic ring cleavage. Transformation of 14C specifically labelled benzene derivatives, [1-6-14C]-nitrobenzene, [1-6-(14)C]-aniline, [1-(14)C]- and [7-(14)C]-benzoic acid, in axenic seedlings of maize (Zea mays L.), kidney bean (Phaseolus vulgaris L.

Detoxication mechanism of exogenous monatomic phenols in pea seedlings.

The conversion of exogenous monatomic phenols (O-[1-(14)C]nitrophenol, 2,4-[1-14C]dinitrophenol, and alpha-[1-14C]naphthol) in pea seedlings has been investigated. It has been found that in the pea seedlings glycosylation of these phenols does not occur, but the main pathway of their detoxication is conjugation with the low-molecular-weight peptides. Approximately 80% of phenols absorbed by seedlings form phenol-peptide conjugates.

[Plant potential for detoxification (review)].

Data on the uptake, excretion, and biodegradation of organic xenobiotics by plants are reviewed. Detoxification pathways operating in plants and their role in remediation of biosphere are described. Structure-, concentration, and time-dependent effects of xenobiotics on the ultrastructural organization of cells are analyzed.

Organic toxicants and plants.

Organic xenobiotics absorbed by roots and leaves of higher plants are translocated by different physiological mechanisms. The following pathways of xenobiotic detoxication have been observed in higher plants: conjugation with such endogenous compounds as peptides, sugars, amino acids, and organic acids; oxidative degradation and consequent oxidation of xenobiotics with the final participation of their carbon atoms in regular cell metabolism. The small parts of xenobiotics are excreted maintaining their original structure and configuration.

Detoxication of phenol in annual plant seedlings.

Transformation of phenol (14C6H5OH) penetrating through the roots of mung bean (Phaseolus aureus) and wheat (Triticum vulgare) sterile seedlings has been studied. Phenol was coupled to low-molecular-weight peptides, producing phenol-peptide conjugates. Hydrolytic cleavage of the conjugates liberated initial labeled phenol and some unlabeled amino acids.

Uptake and transformation of benzene and toluene by plant leaves.

The [1-6(14)C]benzene and [1-(14)C]toluene vapors penetrate into hypostomatous leaves of Acer campestre, Malus domestica, and Vitis vinifera from both sides, whereas hydrocarbons are more intensively absorbed by the stomatiferous side and more actively taken up by young leaves. Benzene and toluene conversion in leaves occurs with the aromatic ring cleavage and their carbon atoms are mainly incorporated into nonvolatile organic acids, while their incorporation into amino acids is less intensive. Intact spinach chloroplasts oxidize benzene, and this process is strongly stimulated in light.
