Skeleton and Calcium Homeostasis

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Feedback Regulation of Calcium Concentration

Feedback Regulation of Calcium Concentration

Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

Mitral Valve Prolapse III: Nursing Management

Mitral Valve Prolapse III: Nursing Management

The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

Synthesis and Functions of Calcitonin

Synthesis and Functions of Calcitonin

Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

Hormones and Bone Tissue

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Background:

Establishing reference ranges for serum calcium and urinary calcium excretion is crucial for monitoring maternal and fetal health during pregnancy.
Calcium intake and status can be influenced by various demographic and socioeconomic factors in pregnant populations.

Purpose of the Study:

To determine reference values for serum calcium concentration and 24-hour urinary calcium excretion in pregnant women during their second trimester.
To investigate the variations in dietary calcium intake among pregnant women and identify associated demographic factors.

Main Methods:

A cross-sectional study involving 543 healthy, vegetarian, primigravid women in their second trimester of pregnancy.
Serum and 24-hour urinary samples were collected for calcium level determination.
Dietary calcium intake was assessed using a 3-day recall method, and variations were analyzed against demographic characteristics.

Main Results:

Mean serum calcium was 8.1±1.5 mg/dL, mean 24-hour urinary calcium was 129.56±67.08 mg, and mean daily calcium intake was 324.37±199.47 mg.
The 95th percentiles for serum calcium and urinary calcium excretion were 10.56 mg/dL and 280.70 mg/24 h, respectively.
Higher educational level, monthly income, and height were positively correlated with increased calcium intake.

Conclusions:

This study provides the first standard reference values for calcium status in second-trimester pregnant females in Northern India.
Demographic characteristics significantly influence calcium intake during pregnancy.
Interventions aimed at improving education and socioeconomic status are recommended to enhance dietary calcium patterns in pregnant women.
