Summary
Nigeria
Area of Science:
- Public Health
- Epidemiology
- Immunization Programs
Background:
- Nigeria adopted regional measles elimination targets and implements strategies including routine vaccination and biennial supplemental immunization activities (SIAs).
- Measles case-based surveillance is established in Nigeria.
- Routine vaccination is provided for children aged 9 months.
Purpose of the Study:
- To evaluate Nigeria's progress towards measles elimination targets.
- To analyze measles immunization coverage and surveillance data from 2012-2016.
Main Methods:
- Review of routine and supplemental measles immunization coverage data.
- Analysis of measles case-based surveillance data.
- Utilized WHO UNICEF national coverage estimates and survey data.
Main Results:
- Routine first-dose measles vaccination coverage ranged from 42%-54% (2012-2015).
- Post-2015 SIAs achieved 84.5% coverage.
- Confirmed measles incidence varied (25-300 cases/million/year), with higher rates in Northern States and a shift in susceptibility to older children.
Conclusions:
- Sustainable population immunity requires addressing systemic issues to scale up routine immunization, particularly in Northern Nigeria.
- Tailoring measles SIAs to target age groups with high disease incidence is crucial.
- Effective resource mobilization and improved SIA planning and outcomes are necessary for accelerated progress.

Kinetics of Drug Elimination
4.1K
Eliminating drugs from the body is a vital process that occurs through excretion or metabolism. Understanding the kinetics of drug elimination is crucial for drug development, dosage determination, and optimizing patient outcomes.
Drug clearance depends on the rate of drug elimination and its plasma concentration. Another important parameter is the half-life of a drug, which is the time required for its concentration to decrease by half. In most cases, drug clearance follows first-order...

Enhanced Elimination of Poison
881
Poison can be effectively removed from the gastrointestinal (GI) tract through various decontamination procedures.
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
Renal excretion is the...

Radical Formation: Elimination
2.3K
Another method of radical formation is the elimination process. It is the opposite of the addition route and is driven by the instability of the radical. For example, as depicted in Figure 1, dibenzoyl peroxide yields a pair of unstable radicals upon homolysis. Given its instability, this radical spontaneously undergoes elimination via a C–C bond cleavage to form a relatively more stable phenyl radical. The mechanism involves cleavage of the bond between the α and β positions with respect...

Elimination Reactions
16.7K
A nucleophile can react with an alkyl halide to give the substitution product by displacing the halogen. Or it can function as a base to give the elimination product by deprotonation of the neighboring carbon to form an alkene. In an elimination reaction, the substrate loses two groups from adjacent carbons forming at least one π bond. The carbon attached to the halogen is called the α carbon, while the adjacent carbon is called the β carbon; hence, these reactions are called...

Tumor Progression
7.3K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
