Body composition parameters and functional status test in predicting future acute exacerbation risk among hospitalized patients with chronic obstructive pulmonary disease.

Background & Aims: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Nutritional and functional status derangement is a commonly seen in COPD patients, and this is associated with a higher disease severity and mortality. To assess body composition analysis - measured by segmental multi-frequency bioelectrical impedance analysis (BIA)- and functional status and investigate their relationship with the COPD acute exacerbation risk.

The Correlation of Sit-to-Stand Tests with COPD Assessment Test and GOLD Staging Classification.

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) ABCD classification tool has been used to assess the symptom burden and exacerbation risk of patients with chronic obstructive pulmonary disease (COPD). An area requiring further exploration is the relationship between the GOLD classification's basic components and the measurements acquired by Sit-to-Stand tests (STST). We aimed to study the relationship between STST and the component of the GOLD classification tool.

The prognostic efficacy of beta2-microglobulin in acute pulmonary embolism.

Our aim was to prospectively assess the prognostic value of beta2-microglobulin (b2-M) in patients with acute pulmonary embolism (PE). We conducted a prospective study of 109 patients admitted in a pulmonary clinic due to acute PE. A panel of inflammatory markers including b2-M white blood cell (WBC) count and C-reactive protein (CRP) was determined for each patient.

Carboxyhemoglobin and methemoglobin levels as prognostic markers in acute pulmonary embolism.

Objectives: Carboxyhemoglobin (COHb) and methemoglobin (MetHb) levels have been associated with a poor outcome in patients with various pathological conditions including cardiovascular diseases. Our aim was to retrospectively assess the prognostic value of arterial COHb and MetHb in patients with acute pulmonary embolism (PE).

Methods: We conducted a retrospective study of 156 patients admitted in a pulmonary clinic due to acute PE.
