Insights

Vitamin D deficiency affects over 74% of cardiology patients in Mauritania. Higher education, wealth, and inactivity are linked to deficiency, suggesting targets for public health interventions.

Area of Science:

  • Cardiology
  • Endocrinology
  • Public Health

Background:

  • Vitamin D deficiency is a global health concern with potential links to cardiovascular disease.
  • Understanding prevalence and associated factors in specific patient populations is crucial for targeted interventions.

Purpose of the Study:

  • To determine the prevalence of vitamin D deficiency among cardiology patients in Nouakchott, Mauritania.
  • To identify demographic, lifestyle, and clinical factors associated with vitamin D deficiency in this cohort.

Main Methods:

  • A cross-sectional study involving 170 cardiology patients.
  • Serum 25-hydroxyvitamin D [25(OH)D] concentrations were used to assess vitamin D status.
  • Modified Poisson regression was employed to estimate prevalence ratios and identify associated factors.

Main Results:

  • A high prevalence of vitamin D deficiency (74.71%) was observed.
  • Significant associations were found with higher education, household wealth, and reduced physical activity.
  • Factors like non-regular physical activity and non-active status showed increased prevalence ratios for deficiency.

Conclusions:

  • Vitamin D deficiency is highly prevalent in cardiology patients in Nouakchott.
  • Socioeconomic and lifestyle factors are significantly associated with vitamin D deficiency.
  • Findings suggest potential targets for public health strategies and interventions to mitigate cardiovascular risk.

Therapeutic Drug Monitoring: Affecting Factors01:29

Therapeutic Drug Monitoring: Affecting Factors

Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.
Factors Affecting Illness01:18

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...
Factors Affecting Protein-Drug Binding: Patient-Related Factors01:29

Factors Affecting Protein-Drug Binding: Patient-Related Factors

Protein-drug binding, a pivotal aspect of pharmacokinetics, is subject to considerable variability influenced by an array of patient-related factors. The intricate interplay of age, individual differences, and pathological conditions significantly impact the binding dynamics and subsequent pharmacological effects.
Age stands as a key determinant in protein-drug binding. Neonates, characterized by low albumin content, experience heightened concentrations of unbound drugs such as phenytoin and...

Factors affecting Blood pressure

Several physiological and lifestyle factors influence blood pressure (BP). Understanding these factors is crucial as they are significant in patient education and blood pressure management.

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
Factors Influencing Drug Absorption: Disease States and Pharmacology01:25

Factors Influencing Drug Absorption: Disease States and Pharmacology

Multiple disease states can significantly influence the oral drug absorption process by affecting blood flow and the functionality of the gastrointestinal (GI) system. Various GI diseases, including conditions that alter GI motility, such as diarrhea, decreased acid secretions (achlorhydria), and infections, have been associated with reduced drug absorption.
Substances such as alcohol and specific drugs, including antineoplastics, can also negatively impact drug absorption. For instance,...
