Great hopes or disappointment - a survey-based study on patients' and doctors' perception of telemedicine during the COVID-19 pandemic in Poland.

Introduction: During the COVID-19 pandemic health care systems worldwide rapidly implemented telemedicine solutions in order to avoid spreading the coronavirus among doctors and patients. Aim: To analyse the knowledge, usage, and attitude towards telemedicine among patients, dermatologists, and other doctors during the COVID-19 pandemic. Material and methods: An original anonymous online survey was carried between 22 September 2020 and 29 December 2020 in Poland among 121 patients, 63 dermatologists, and 50 doctors of other specialties. Statistical analysis was performed using the χ2 test, and a statistically significant difference was considered at p < 0.05. Results: In the analysed period in the patient group 58.7% suffered from a skin disease and 79.3% used telemedicine during the COVID-19 pandemic, 54.5% of all respondents viewed teleconsultations unfavourably, and 96.6% of dermatologists and 88% of other doctors had to schedule in office visit or ask for additional pictures because of an unclear clinical picture during teleconsultation. There was a statistical significance between dermatologists and other specialty doctors regarding telemedicine's ability to replace office visits, its usefulness in the elderly, and the duration of the teleconsultation compared to a traditional in-person visit (all p < 0.05). Conclusions: The results showed that in many cases issues raised during teleconsultations could not have been solved using telemedicine. The results obtained highlight the unfavourable perception of telehealth. Overall, telemedicine is a safe and useful tool for communicating with patients, increasing access to medical care, but it needs to be evaluated in the context of potential limitations and optimizing the patients' experience.

Elevated circulating Krüppel-like factor 4 level as a novel independent marker of the proatherogenic risk in patients with psoriasis: a preliminary study.

INTRODUCTION: Krüppel-like factor 4 (KLF4) is a transcription factor of anti-inflammatory and anti-thrombotic properties not studied in psoriasis yet. AIM: To analyze the clinical value of the serum KLF4 level in psoriatics and elucidate the interplay between disease activity, metabolic or inflammatory parameters and systemic therapy. MATERIAL AND METHODS: The study enrolled thirty-four psoriatics and fifteen healthy subjects. Blood samples were collected before and after twelve weeks of treatment with methotrexate or acitretin. Serum KLF4 levels were measured using immune-enzymatic method. RESULTS: Serum KLF4 levels in psoriatic patients did not statistically differ comparing to the controls (p > 0.05). However, in severe psoriasis, KLF4 was significantly higher than in healthy ones before treatment and normalized after treatment to baseline levels of controls (p < 0.05, p > 0.05, respectively). KLF4 positively correlated with body mass index (p = 0.038) but not with psoriasis severity, nor inflammatory or metabolic markers. Interestingly, many pro-atherogenic parameters were shown as variables independently predicting the levels of KLF4. No significant effect of three-month systemic treatment on KLF4 was found. CONCLUSIONS: KLF4 may be a novel independent indicator of the proatherogenic risk in psoriatics, especially with a severe form or obesity.
