Outcome Measures
Primary Outcomes (26)
Respiratory muscle force: Maximal inspiratory pressure - MIP
This test involves wearing a nose peg and inhaling through a tube, performed in three trials.
up to 18 months
Respiratory muscle force: Maximal expiratory pressure - MEP
This test involves wearing a nose peg and exhaling through a tube, performed in three trials.
up to 18 months
Respiratory muscle force: Sniff Nasal Inspiratory Pressure - SNIP
The test consists of separate inhalations through the left and right nostrils, performed in five trials per nostril.
up to 18 months
6-Minute Walk Test - 6MWT
The 6-Minute Walk Test (6MWT) is a standardized test used to assess functional exercise capacity. It measures the distance an individual can walk on a flat, hard surface in a period of six minutes
up to 18 months
The Aggregation Index (AI)
The Aggregation Index (AI), indicating the extent of red blood cell aggregation, is measured using the Lorrca Maxis (Laser-Assisted Optical Rotational Cell Analyzer) under standardized shear conditions. (AI) analyzed
up to 18 months
The half-time of total aggregation (T1/2)
The half-time of total aggregation (T1/2), which reflects the time required for red blood cells to aggregate to 50% of their maximum value, is assessed using the Lorrca Maxis (Laser-Assisted Optical Rotational Cell Analyzer). This test measures the aggregation kinetics of erythrocytes under controlled shear stress, providing a quantitative assessment of the aggregation process.
up to 18 months
The Elongation Index (EI)
The Elongation Index (EI), reflecting red blood cell deformability, is measured using the Lorrca Maxis (Laser-Assisted Optical Rotational Cell Analyzer), which evaluates the ability of erythrocytes to deform under varying shear stress.
up to 18 months
4- Meters Gait Speed Test - 4MGST
The 4-Meters Gait Speed Test (4MGST) is a simple, widely used assessment tool to measure an individual's walking speed over a short, fixed distance. It is primarily used to evaluate mobility and functional performance, especially in elderly individuals.
up to 18 months
Health Related Quality of Life - HRQoL withe the use of 15D questionnaire.
The 15D is a comprehensive, generic health-related quality of life (HRQoL) tool that measures an individual's overall health status. It includes 15 dimensions, covering aspects of physical, mental, and social well-being.Minimum Value: 0 (representing the worst possible health state) Maximum Value: 1 (representing the best possible health state). Higher Scores indicate better health-related quality of life, reflecting higher levels of functioning and well-being across the 15 dimensions.
up to 18 months
Chest mobility
The assessment of chest mobility involves evaluating the range of motion (ROM) and the expansion of the chest during inspiration and expiration, performed in three trials.
up to 18 months
Back scratch test
The patient is instructed to reach with his dominant hand behind his head, over the shoulder, as if trying to scratch the back of their neck. The fingers should be pointing downward toward the spine.The distance between the fingers (or whether they touch) is measured to assess the flexibility and range of motion of the shoulder and upper back.
up to 18 months
Interleukin IL 1b
Interleukin-1 beta (IL-1β) is a pro-inflammatory cytokine produced primarily by activated macrophages and monocytes. It plays a central role in the regulation of immune and inflammatory responses and is considered a key mediator in the pathophysiology of various chronic inflammatory, autoimmune, and infectious diseases.
up to 18 months
Interleukin IL-6
Interleukin-6 (IL-6) is a pleiotropic pro-inflammatory cytokine produced by various cell types, including macrophages, T cells, B cells, endothelial cells, fibroblasts, and skeletal muscle cells. It plays a key role in the regulation of immune responses, inflammation, hematopoiesis, and metabolism.
up to 18 months
TNF-alfa
Tumor Necrosis Factor alpha (TNF-α) is a key pro-inflammatory cytokine involved in the regulation of immune responses, inflammation, and apoptosis. It is produced primarily by activated macrophages, but also by T lymphocytes, natural killer (NK) cells, and other immune and non-immune cells in response to infection, injury, or immune stimulation.
up to 18 months
WBC [10⁹/l]
White Blood Cell Count - WBC \[10⁹/l\] Represents the number of leukocytes in one liter of blood. WBCs play a crucial role in immune defense. Elevated levels may indicate infection, inflammation, physiological stress, or hematologic malignancies. Decreased levels can be associated with bone marrow suppression or immunodeficiency.
up to 18 months
RBC [10¹²/l],
Red Blood Cell Count - RBC \[10¹²/l\] Indicates the number of erythrocytes per liter of blood. RBCs are responsible for oxygen transport. Decreased levels suggest anemia; elevated levels may indicate dehydration or polycythemia.
up to 18 months
HGB [g/dl]
Hemoglobin Concentration - HGB \[g/dl\] Measures the amount of hemoglobin in the blood. Hemoglobin is the oxygen-carrying protein in red blood cells. It is a key indicator of oxygen-carrying capacity and a primary marker for diagnosing anemia.
up to 18 months
HCT [%]
Hematocrit - HCT \[%\] Refers to the percentage of total blood volume occupied by red blood cells. Lower values are commonly seen in anemia; higher values may indicate dehydration or polycythemia.
up to 18 months
MCV [fl]
Mean Corpuscular Volume - MCV \[fl\] Reflects the average volume of individual erythrocytes. It helps to classify anemia as microcytic, normocytic, or macrocytic.
up to 18 months
MCH [pg]
Mean Corpuscular Hemoglobin -MCH \[pg\] Indicates the average amount of hemoglobin per red blood cell. It provides additional insight into the hemoglobin content in different types of anemia.
up to 18 months
MCHC [g/dl]
Mean Corpuscular Hemoglobin Concentration - MCHC \[g/dl\] Represents the average concentration of hemoglobin in erythrocytes. Decreased levels suggest hypochromia, commonly observed in iron deficiency anemia.
up to 18 months
PLT [109/l]
Platelet Count - PLT \[10⁹/l\] Determines the number of platelets in one liter of blood. Platelets are essential for blood clotting. Thrombocytopenia increases bleeding risk, while elevated platelet counts may indicate inflammation or a prothrombotic state.
up to 18 months
Reticulocytes {% or ‰]
Reticulocytes \[% or ‰\] Immature red blood cells that reflect bone marrow erythropoietic activity. Increased reticulocyte counts indicate active regeneration, commonly seen in response to anemia or blood loss.
up to 18 months
CRP [mg/l]
C-Reactive Protein - CRP \[mg/l\] An acute-phase protein produced by the liver in response to inflammation. Elevated CRP levels are a sensitive but non-specific marker of acute inflammation, infection, or tissue injury.
up to 18 months
Fibrinogen [g/l]
Fibrinogen A coagulation factor and acute-phase reactant synthesized in the liver. Increased fibrinogen levels are observed during inflammation, infection, or trauma and may contribute to a hypercoagulable state.
up to 18 months
ESR [mm/h]
Erythrocyte Sedimentation Rate - ESR \[mm/h\] A non-specific indicator of inflammation that measures the rate at which red blood cells settle in a vertical tube over one hour. Elevated ESR values are commonly found in infections, autoimmune diseases, and malignancies.
up to 18 months
