Effectiveness of inactivated SARS-CoV-2 vaccine (CoronaVac) on intensive care unit survival.

This study compared the course of coronavirus disease 2019 (COVID-19) in vaccinated and unvaccinated patients admitted to an intensive care unit (ICU) and evaluated the effect of vaccination with CoronaVac on admission to ICU. Patients admitted to ICU due to COVID-19 between 1 April 2021 and 15 May 2021 were enrolled to the study. Clinical, laboratory, radiological parameters, hospital and ICU mortality were compared between vaccinated patients and eligible but unvaccinated patients. Patients over 65 years old were the target population of the study due to the national vaccination schedule. Data from 90 patients were evaluated. Of these, 36 (40.0%) were vaccinated. All patients had the CoronaVac vaccine. Lactate dehydrogenase and ferritin levels were higher in an unvaccinated group than vaccinated group (P = 0.021 and 0.008, respectively). SpO2 from the first arterial blood gas at ICU was 83.71 ± 19.50% in vaccinated, 92.36 ± 6.59% in unvaccinated patients (P = 0.003). Length of ICU and hospital stay were not different (P = 0.204, 0.092, respectively). ICU and hospital mortality were similar between groups (P = 0.11 and 0.70, respectively). CoronaVac vaccine had no effect on survival from COVID-19. CoronaVac's protective effect, especially on new genetic variants, should be investigated further.

Sigara Kullanımının Yoğun Bakım Ünitesindeki COVID-19 Hastalarında Sağkalıma Etkisi

Amaç: Bu çalışmada yoğun bakım ünitemizde (YBÜ) sigara içme sıklığı/ yaygınlığının (prevalansının), sigara kullanımına bağlı kalış süresinin ve COVID-19 mortalitesi üzerine etkilerini görmeyi amaçladık. Gereç ve Yöntem: 16 Mart-16 Mayıs 2020 tarihleri arasında COVID19 hastaları üzerinde yoğun bakım ünitesinde yapılan retrospektif tek merkezli bir çalışmadır. Demografik veriler, komorbidite durumları, kabul edildikleri birimler, klinik semptomlar, solunum desteği, hastaların sigara içme sıklığı/prevalansı, yoğun bakımda kalış süreleri ve mortaliteleri kaydedilmiştir. Sigara içen ve içmeyen olarak iki grup vardı. 1.100 COVID19 hastası vardı ve bunlardan 150’si yoğun bakım ünitesinde tedavi gördü. Doksan beş hastanın verilerine ulaşıldı. Bulgular: Hiç sigara içmemiş hastalar %64,2’di. Bu hastaların %5,3’ü daha önce sigara içmiş, %30,5’i ise aktif içici idi. Sigara içen gruptaki hastaların yaş ortalaması içmeyenlere göre daha az olmuştur. Sigara içenlerde kronik obstrüktif akciğer hastalığı insidansı daha yüksek olmuştur. Sigara içme durumu, yoğun bakımda kalış süresi ve sağkalım arasında ilişki bulunamamıştır. Sigara kullanımı, COVID-19 hastalığında solunum yetmezliğine kadar ilerleyebilen ve ölümle sonuçlanabilen agresif sürece neden olan faktörler arasında yer almaktadır. Sonuç: Bazı araştırmalar da sigaranın koruyucu olabileceğini iddia etmektedir. Bu konu hakkında henüz bir netlik yoktur. COVID-19 pnömonisine bağlı solunum yetmezliği olan YBÜ’de tedavi edilen hastalarda sigara içmenin yoğun bakımda kalış süresi ve mortalite üzerinde etkisi olmadığı ortaya konmuştur.

Evaluation of the effect of clinical characteristics and intensive care treatment methods on the mortality of covid-19 patients aged 80 years and older.

BACKGROUND: Older adults have an increased risk of mortality from Coronavirus disease 2019 (Covid-19). Despite the high number of publications on the topic of Covid-19 pandemic, few studies have focused on the intensive care treatments of Covid-19 patients aged 80 years and older. The goal of our study is to investigate the effect of the intensive care treatments on the mortality of Covid-19 patients aged 80 years and older based on their clinical features, laboratory findings and the intensive care treatments methods. METHODS: The data of 174 patients aged 80 years and older treated from Covid-19 in intensive care unit were assessed retrospectively. The patients were divided into two groups as survivor and non-survivor. The effects of age, gender, length of stay, comorbid diseases, laboratory values, thoracic computed tomography findings, having invasive mechanical ventilation (IMV), high flow nasal cannula (HFNC) and/or non-invasive mechanical ventilation (NIMV), hemodiafiltration (HDF), anti-cytokines and plasma therapy on mortality have been investigated. RESULTS: The mean age and mean values of CRP, PCT, Ferritin, LDH were statistically significantly high in the non-survivor group. The mortality rate of the patients who had IMV was also statistically significantly higher compared to patients who had HFNC and/or NIMV. Albumin level and the rate of treatment with HFNC and/or NIMV were statistically significantly low in non-survivor group compared to the Survivor group. CONCLUSION: ICU treatments may be beneficial for the Covid-19 patients aged 80 years and older. Increased age, high levels of CRP, PCT, ferritin, and having IMV are detected as poor outcome markers.

Anxiety and burnout in anesthetists and intensive care unit nurses during the COVID-19 pandemic: a cross-sectional study.

BACKGROUND: This study aimed to measure the levels of anxiety and burnout among healthcare workers, including attending physicians, residents, and nurses in intensive care units during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This is a cross-sectional survey analysis of healthcare workers in our institution. Data were collected on demographic variables, COVID-19 symptoms and test, disease status, anxiety level (assessed by the Beck Anxiety Inventory), and burnout level (measured by the Maslach Burnout Inventory). Subscales of the burnout inventory were evaluated separately. RESULTS: A total of 104 participants completed the survey. Attending physicians, residents, and nurses constituted 25%, 33.7%, and 41.3% of the cohort, respectively. In comparison to untested participants, those tested for COVID-19 had a lower mean age (p = 0.02), higher emotional exhaustion and depersonalization scores (p = 0.001, 0.004, respectively), and lower personal accomplishment scores (p = 0.004). Furthermore, moderate to severe anxiety was observed more frequently in tested participants than untested ones (p = 0.022). Moderate or severe anxiety was seen in 23.1% of the attending physicians, 54.3% of the residents, and 48.8% of the nurses (p = 0.038). Emotional exhaustion, personal accomplishment, and depersonalization scores differed depending on the position of the healthcare workers (p = 0.034, 0.001, 0.004, respectively). CONCLUSION: This study revealed higher levels of anxiety and burnout in younger healthcare workers and those tested for COVID-19, which mainly included residents and nurses. The reasons for these observations should be further investigated to protect their mental health.

Could we predict the prognosis of the COVID-19 disease?

OBJECTIVES: Coronavirus 2019 disease (COVID-19) lead to one of the pandemics of the last century. We aimed to predict poor prognosis among severe patients to lead early intervention. METHODS: The data of 534 hospitalized patients were assessed retrospectively. Risk factors and laboratory tests that might enable the prediction of prognosis defined as being transferred to the intensive care unit and/or exitus have been investigated. RESULTS: At the admission, 398 of 534 patients (74.5%) were mild-moderate ill. It was determined that the male gender, advanced age, and comorbidity were risk factors for severity. To estimate the severity of the disease, receiver operating characteristic analysis revealed that the areas under the curve which were determined based on the optimal cut off values that were calculated for the variables of values of neutrophil to lymphocyte ratio (NLR > 3.69), C-reactive protein (CRP > 46 mg/L), troponin I ( > 5.3 ng/L), lactate dehydrogenase (LDH > 325 U/L), ferritin ( > 303 ug/L), d-dimer ( > 574 µg/L), neutrophil NE ( > 4.99 × 109 /L), lymphocyte (LE < 1.04 × 109 /L), SO2 ( < %92) were 0.762, 0.757,0.742, 0.705, 0.698, 0.694,0.688, 0.678, and 0.66, respectively. To predict mortality, AUC of values for optimal cutoff troponin I ( > 7.4 ng/L), age ( > 62), SO2 ( < %89), urea ( > 40 mg/dL), procalcitonin ( > 0.21 ug/L), CKMB ( > 2.6 ng/L) were 0.715, 0.685, 0.644, 0.632, 0.627, and 0.617, respectively. CONCLUSIONS: The clinical progress could be severe if the baseline values of NLR, CRP, troponin I, LDH, are above, and LE is below the specified cut-off point. We found that the troponin I, elder age, and SO2 values could predict mortality.
