Identification of important clinical variables for the severe course of COVID-19 in hospitals: A systematic review

Infection with the new coronavirus transformed the world from 2019 onwards. The severity of this respiratory syndrome caused by SARS-Cov-2 has divergent opinions on the causes of injuries and deaths. The objective of this study was to identify factors in the sociodemographic and clinical profile that are possibly related to COVID-19 cases that lead to hospitalization. This is a systematic review, in which the search strategy was defined by the acronym PECOS. The search was carried out in the scientific reference databases: MEDLINE via PubMed, Cochrane Library of Cochrane and; in specific databases: EMBASE via Elsevier and LILACS. Observational studies of the prospective cohort type without the use of filters were included. Exposure was considered as hospitalization for COVID-19 with a positive test and the individuals not exposed were those hospitalized with unconfirmed suspicion. The monitoring of the cohorts carried out by the studies lasted an average of 77.6±54.8 days. The mean time of infection of the patients was 9.5±22.32 days with a mean isolation period of 9.5±4.81 days. The symptoms commonly presented by the exposure group were: fever 787 (2.84%) cases, headache 658 (2.37%) cases, cough, sore throat, decreased appetite, headache, diarrhea. Factors such as age, 41.16±11.27 years; Non-essential occupation (79.79%) and medium and low education were evident in the exposure group. Respiratory diseases (0.22%), p= 0.045 and chronic kidney disease (0.08%), p= 0.038 were characteristics of the clinical profile for the exposed individuals. It is concluded that individuals with characteristic flu-like symptoms and diarrhea, with a profile of non-elderly adulthood, lower education, with non-essential occupation and who have characteristics of respiratory diseases and chronic kidney disease are more likely to be hospitalized for COVID-19.

Epidemiological investigation on respiratory diseases in 1 300 children, in Jinan, Shandong

To analyze the characteristics of respiratory diseases and to provide scientific basis for developing relevant control measures. 1 300 children with respiratory diseases were treated in hospitals, from Jan. 2013 to May 2014, in the city of Jinan. Characteristics of respiratory diseases were analyzed. The distribution of respiratory diseases in children appeared as: 373 cases of pneumonia (28.7%), 3 cases of pulmonary tuberculosis (0.2%), 467 cases of acute bronchitis (35.9%), 102 cases of asthma (7.8%), and 355 cases of upper respiratory tract infection (27.3%). The upper respiratory tract infection contained 168 cases of tonsillitis (12.9%), 91 cases of pharyngitis (7.0%), 52 cases of laryngitis(4.0%)and 44 cases of iaryngopharyngitis (3.4%). The age distribution of cases with children respiratory diseases appeared as:71 cases <1 years old (5.5%), 385 cases as 1-2 years old (29.6%), 534 cases as 3-6 years old (41.1%), 258 cases as 7-12 years old (19.8%)and 52 cases as >13 years old (4.0%). The seasonal distribution of children respiratory diseases appeared as:364 cases in Spring (28.0% ), 163 cases in summer (12.5%), 315 cases in autumn (24.2%)and 458 cases in winter (35.2%). Regional distribution of children respiratory diseases appeared as:516 cases in urban area (39.7%), 225 cases in suburb (17.3%), 376 cases in townships (28.9%)and 183 in villages (14.1%). 725 strains were isolated and identified that containing 349 strains(48.1%) of Mycoplasma pneumoniae, 136 strains (18.8%) of Haemophilus influenza, 103 strains (14.2% ) of Streptococcus pneumoniae, 82 strains (11.3% ) of Klebsiella pneumoniae, 38 strains (5.2%) of Acinetobacter baumannii, 35 strains(4.8%) of Enterobacter cloacae, 22 strains (3.0%) of Streptococcus pyogenes, 17 strains (2.3%) of Alcaligenes, 16 strains (2.2% of Candida albicans)and 9 strains (1.2%) of Flavobacterium indologenes. 1 288 cases (99.1%) were cured. The common respiratory diseases would include bronchiolitis, pneumonia and upper respiratory tract infections in children, mostly attacking 3-6 year-olds at preschool stage, with spring, winter, urban and township as the prevalent seasons and areas.
