It improves quality of life and decreases mortality in patients with an arterial PO2 of 55 mm Hg (7.3 kPa) or less or an oxygen saturation of 88% or less.
What are the adjusted thresholds for supplemental oxygen therapy in patients with COPD who have cor pulmonale, heart failure, or erythrocytosis?
The thresholds are lowered to a PO2 of 59 mm Hg (7.8 kPa) or less or oxygen saturation of 89% or less.
What is neutropenia defined as?
A circulating absolute neutrophil count (ANC) less than 1500/μL (1.5 × 10^9/L)
Neutropenia indicates a lower than normal level of neutrophils, a type of white blood cell essential for fighting infections.
What is the ANC threshold for severe neutropenia?
An ANC less than 500/μL (0.5 × 10^9/L)
Severe neutropenia significantly increases the risk of infections and requires careful monitoring.
What is drug-induced neutropenia?
Impairment of normal granulopoiesis in the bone marrow or drug-dependent, antibody-mediated immune destruction of circulating neutrophils.
Granulopoiesis is the production of neutrophils in the bone marrow.
Which drugs are known to cause agranulocytosis?
Thionamides such as propylthiouracil and methimazole.
Agranulocytosis is a severe reduction in neutrophils, increasing the risk of infections.
What is the overall prevalence of agranulocytosis caused by thionamides?
Around 0.5%.
While low, this prevalence indicates a notable risk associated with these medications.
When is the risk of agranulocytosis highest after chemotherapy drug initiation?
Within the first 3 months.
Early monitoring is crucial during this period.
Is agranulocytosis more common in men or women?
More common in women.
Gender differences can influence drug reactions and side effects.

Every 3 weeks
This regular recurrence pattern is a key characteristic of cyclic neutropenia.
What is the severity of neutropenia in cyclic neutropenia?
Severe (<200/μL [0.2 × 109/L])
This low level of neutrophils can significantly impair the body’s ability to fight infections.
How long does neutropenia last during each episode of cyclic neutropenia?
2 to 3 days
The duration of neutropenia can lead to increased vulnerability to infections during this period.
What symptoms are associated with cyclic neutropenia?
Recurrent fever, oral ulcerations, and infections
These symptoms are a result of the body’s reduced ability to combat infections due to low neutrophil counts.
What are characteristic findings of serous cystadenomas?

When should tuberculosis screening be repeated in persons with HIV?
When the CD4 cell count rises to 200/µL, especially if previous testing was negative and the patient has significant risk factors.
This is critical to ensure early detection and management of tuberculosis in at-risk populations.
What is the risk for Mycobacterium avium complex (MAC) infection in persons with advanced HIV?
Low, if the pretreatment CD4 cell count is more than 50/µL and there is a remarkable increase following effective ART.
This indicates that effective ART can significantly lower the risk of opportunistic infections.
What is the utility of performing acid-fast bacilli blood cultures for evaluating disseminated MAC infection in patients with advanced HIV?
Little to no utility.
This suggests that other diagnostic methods may be more effective in this patient population.
Is it appropriate to start active tuberculosis treatment without confirmatory testing for tuberculosis infection?
No, it puts patients at risk for complications.
Active tuberculosis treatment should always be based on confirmed diagnosis to avoid unnecessary adverse effects.
