Chronic thromboembolic pulmonary hypertension: A great mimic.

Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare and underdiagnosed condition, often presenting with variable symptoms, making it challenging to identify. This case report highlights the clinical relevance of CTEPH, emphasizing its misdiagnosis as asthma and the need for increased awareness in recognizing its atypical presentations.

Objective: To present a case of CTEPH misdiagnosed as asthma, showcasing the importance of early identification and raising awareness about the underrepresentation of this disease.

Detection of swine influenza virus in nasal specimens by reverse transcription-loop-mediated isothermal amplification (RT-LAMP).

Detection of swine influenza virus (SIV) in commercial swine herds is important for understanding the infection status of the herd and for controlling disease. Current molecular diagnostics require that specimens be submitted to a laboratory which provides results to the growers after some time which is generally too late to intercede in disease control. Moreover, current diagnostic assays are time-consuming, typically costly, and require skilled technical expertise.

Molecular epidemiology and glycomics of swine influenza viruses circulating in commercial swine farms in the southeastern and midwest United States.

Tracking the genetic diversity and spread of swine influenza viruses (SIVs) in commercial swine farms is central for control and to reduce the potential emergence of SIV reassortants. We analyzed the diversity of SIVs in nasal washes or oral fluids from commercial swine farms in North Carolina using influenza M qRT-PCR and hemagglutinin (HA) and neuraminidase (NA) subtyping. We found a predominance of H1 HAs and N2 NAs in the samples examined.
