Short-Term Outcomes of Patients With COVID-19 Undergoing Invasive Mechanical Ventilation: A Retrospective Observational Study From Wuhan, China.

2020

Background: COVID-19 has spread rapidly worldwide. Many patients require mechanical ventilation. The goal of this study was to investigate the clinical course and outcomes of patients with COVID-19 undergoing mechanical ventilation and identify factors associated with death. Methods: Eighty-three consecutive critically ill patients with confirmed COVID-19 undergoing invasive mechanical ventilation were included in this retrospective, single-center, observational study from January 31 to March 15, 2020. Demographic, clinical, laboratory, radiological, and mechanical ventilation data were collected and analyzed. The primary outcome was 28-day mortality after endotracheal intubation. The secon…

The prognostic role of tumor budding and tumor-stroma ratio in pulmonary metastasis of colorectal carcinoma

2023

Objective To evaluate the prognostic value of tumor budding and tumor-stroma ratio (TSR) in resected pulmonary metastases of colorectal carcinoma (CRC). Methods In total, 106 pulmonary metastasectomies were performed to 74 patients in two study hospitals during 2000–2020. All relevant clinical data were retrospectively collected. Tumor budding based on the International Tumor Budding Consensus Conference recommendations and TSR in the first resected pulmonary metastases and primary tumors were evaluated from diagnostic hematoxylin-eosin-stained histopathological slides. Results 60 patients (85.7%) had low tumor budding (≤5 buds/field) and 10 patients (14.3%) had high tumor budding (>5 buds/…

The combined effect of lower extremity function and cognitive performance on perceived walking ability among older people : a 2-year follow-up study

2018

Background We studied the combined effects of cognitive performance and lower extremity function on self-reported walking modifications and walking difficulty and on self-reported walking difficulty incidence over a 2-year follow-up. Methods A total of 848 community-dwelling older people aged 75-90 years participated at baseline, 816 at the 1-year follow-up, and 761 at the 2-year follow-up. Baseline lower extremity function was measured with the Short Physical Performance Battery (<10 vs. ≥10) and cognitive performance with the Mini-Mental State Examination (<24 vs. ≥24). Difficulty in walking 2 km was self-reported and categorized into no difficulties, no difficulties but walking modificat…

Harmoniset funktiot kompleksialueessa ja konformikuvaukset

2014

Tämän tutkielman tarkoituksena on syventää tietoja kompleksianalyysistä tutustumalla harmonisiin funktioihin ja konformikuvauksiin. Funktioita, jotka toteuttavat Laplacen yhtälön, kutsutaan harmonisiksi funktioiksi. Harmonisten funktioiden määrittämiseen voidaan käyttää Cauchy-Riemannin yhtälöitä. Harmoniset funktioit ovat yhteydessä analyyttisiin funktioihin, sillä harmonisten funktioiden avulla voidaan selittää analyyttisten kuvausten teoriaa ja päinvastoin. Tämän tutkielman kannalta tärkeimpiä analyyttisiä kuvauksia ovat injektiiviset kuvaukset, jotka tunnetaan myös konformikuvauksina. Konformikuvaukset ovat alueiden välisiä kuvauksia, jotka säilyttävät kulmien suuruuden ja suunnan ja jo…

Personal activity intelligence and mortality : Data from the Aerobics Center Longitudinal Study

2021

Importance Personal activity intelligence (PAI) is a novel activity metric that can be integrated into self-assessment heart rate devices, and translates heart rate variations during exercise into a weekly score. Previous studies relating to PAI have been conducted in the same populations from Norway where the PAI metric has been derived, limiting generalizability of the results. Objective To test whether PAI is associated with total and cause-specific mortality in a large cohort from the United States. Design Aerobics Center Longitudinal Study (ACLS) - a prospective cohort between January 1974 and December 2002 with a mean follow-up of 14.5 years. Setting Population-based. Participants 56,…

Sleep Duration and Risk of Fatal Coronary Heart Disease, Sudden Cardiac Death, Cancer Death, and All-Cause Mortality

2018

Background: Sleep duration has been shown to be associated with all-cause mortality, however its relationship with cause-specific fatal events remains uncertain. We examined the relationship between sleep duration and risk of fatal coronary heart disease (CHD), sudden cardiac death, cancer related death and all-cause mortality. Methods Sleep duration was self-reported at baseline examinations performed between March 20, 1984 and December 5, 1989 in 2,361 men aged 42-61 years old from the Kuopio Ischemic Heart Disease study. Of these 1734 (73.4%) men were free from CHD and cancer at baseline. Results: A total of 802 all cause deaths, 202 fatal coronary heart disease events, 141 sudden cardia…

The parasitoid species complex associated with sexual and parthenogenetic Naryciinae (Lepidoptera: Psychidae): Integrating ecological and molecular a…

2011

This study describes the parasitoid species complex associated with seven closely related species of sexual (Siederia rupicollella, S. listerella, Dahlica lazuri, D. charlottae and D. lichenella) and parthenogenetic (Dahlica fennicella and D. triquetrella) Naryciinae (Lepidoptera: Psychidae) in Central Finland. A thorough ecological analysis of all the species of parasitoids recorded was combined with analyses of molecular data. Mitochondrial and nuclear DNA data were obtained from all the species in order to (1) detect cryptic species associated with host specialization, (2) assign undescribed males to females, and (3) verify the morphological identification of closely related species. A D…

Religious Struggle and Psychological Well-Being: The Mediating Role of Religious Support and Meaning Making

2020

Although a variety of studies have found robust links between religious/spiritual (r/s) struggle and poorer well-being, only a few have examined the means by which r/s struggle affects mental well-being. The present paper aims to examine religious support and meaning making as mediators of the relationship between r/s struggle and well-being. The study included 226 adults, 108 women and 118 men, aged between 17 and 78 years. We applied the Religious and Spiritual Struggle Scale, Religious Support Scale, Meaning Making Scale, and Psychological Well-Being Scale. The results demonstrated that both religious support and meaning making were mediators in the relationship between r/s struggles and…
