Tele-rehabilitation in COVID-19 survivors (TERCOV): An investigator-initiated, prospective, multi-center, real-world study.

Introduction: Center-based rehabilitation is limited by COVID-19 infectivity and social distancing policy. We hypothesized that discharged patients benefit from 8-week home-based tele-rehabilitation (tele-PR) using mobile phones and low-cost instruments.

Methods: The TERCOV (Tele-rehabilitation in COVID-19 survivors) is an investigator-initiated, prospective, multi-center, real-world study.

Prevalence of Chronic Obstructive Pulmonary Disease and Its Associated Risk Factors in Yunnan Province, China: A Population Based Cross-Sectional Study.

Purpose: Chronic obstructive pulmonary disease (COPD) is a significant disease impacting health and quality of life. Yunnan Province, a major tobacco producer, lacks comprehensive COPD studies. The purpose of this study is to describe the epidemic situation of COPD in Yunnan province and explore its influencing factors.

Pulmonary telerehabilitation and efficacy among discharged COVID-19 patients: Rational and design of a prospective real-world study.

Introduction: The novel coronavirus disease 2019 (COVID-19) could cause physical and psychological dysfunction in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected patients. Pulmonary telerehabilitation is strongly recommended due to the contagious nature of the disease, but its efficacy and benefit need to be comprehensively evaluated.

Methods: An 8-week pulmonary telerehabilitation programme is designed in a real-world and prospective manner, aiming to assess the efficacy of remote rehabilitation among discharged patients with COVID-19 from three designated hospitals in the epicenter of China (Wuhan City).

Platelet count trends and response to fondaparinux in a cohort of heparin-induced thrombocytopenia suspected patients after pulmonary endarterectomy.

A definitive diagnosis of heparin-induced thrombocytopenia (HIT) is difficult to make, especially in patients undergoing cardiac surgery. In this retrospective cohort study, we assessed the platelet count trends and the response to fondaparinux in a population of patients of suspected HIT after pulmonary endarterectomy (PEA). Patients enrolled in this study were over the age of 18 years, and survived longer than 7 days after PEA between January 1, 2011 and December 31, 2015.

Dual-band transmission polarization converter based on planar-dipole pair frequency selective surface.

A novel linear polarization converter operating in C- and X-bands with high polarization conversion ratio is described and demonstrated based on frequency selective surface. The building element is a planar-dipole pair, which is orthogonally printed on a double-layer substrate and vertically connected by a pair of through-via holes functioning as a quasi-two-wire transmission line coupler. A perforated metal shielding layer is sandwiched between the double-layer structure to only support a transverse electric and magnetic (TEM) mode coupling between the top and bottom dipolar components.
