The objective of this study was to evaluate the clinical characteristics and outcomes of 1,013 patients hospitalized with SARS-CoV-2 CAP from September 2020 through March 2021 in Louisville, Kentucky. Methods: This was a retrospective observational study of 1,013 patients hospitalized with SARS-CoV-2 CAP at eight of the adult hospitals in the city of Louisville from Septem- ber 2020 through March 2021. Patients with 1) a positive reverse transcriptase-polymerase chain reaction (RT-PCR) for SARS-CoV-2, 2) fever, cough, or shortness of breath, and 3) an infiltrate on chest imaging were defined as having SARS- CoV-2 CAP. Data were abstracted from each hospital’s electronic health record. Descriptive statistics were performed on clinical and epidemiological characteristics of hospitalized patients with SARS-CoV-2 CAP. Demographic characteristics of the study population were compared with census data from the city of Louisville. Data were analyzed by descriptive and inferential statistics using R version 3.4.0. Results: Of the 1,013 patients hospitalized with SARS-CoV- 2 CAP, the median age was 65 years, 53% were males, 24% reported their race as African American or Black, and 6% identified as Hispanic. The most frequent comorbidities were hypertension (73%), obesity (56%), and diabetes (43%). At the time of admission, 60% required supplemental oxygen. The mortality rate was 19% for the total population and 45% for the 359 patients admitted to the intensive care unit (ICU). For each comorbidity, the proportion of hospital- ized patients with SARS-CoV-2 CAP was significantly different from the Louisville population ( P < 0.001). No significant differences were noted in race or ethnicity compared to the city of Louisville. Conclusions: The elderly, males, and patients with a history of coronary artery disease, cerebrovascular disease, chronic obstructive pulmonary disease, hypertension, diabetes, renal disease, or obesity are overrepresented among hospitalized patients with SARS-CoV-2 CAP compared to the Louisville population. These patients are also more likely to require ICU care and experience worse clinical outcomes, with death oc- curring in approximately one in every five hospitalizations.","PeriodicalId":91979,"journal":{"name":"The University of Louisville journal of respiratory infections","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82788709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We reviewed English- language publications on the degree of association between pneumonia and subsequent LC. Methods: We searched the PubMed database using key- words for pneumonia, LC, and Chlamydia infection. We selected peer-reviewed studies of patients with pneumonia and LC. Case reports and other literature reviews were excluded from this review. Results: Five studies examined the incidence and/or risk of LC for a total of 415,750 patients, and four studies examined cases with Chlamydia pneumoniae chronic infection at the time of diagnosis of LC for a total of 1,467 patients. The overall risk and/or incidence of LC after pneumonia was from 2.3% to 10% for a median follow-up ranging from 109 days to 4.2 years. Three studies reported current tobacco smok- ing status, which ranged from 27.7% to 45% among those with LC. A history of prior malignancy was reported in 22.5% of patients with LC. Chlamydia immunoglobulin (Ig) A and LC were statistically non-significantly associated regardless of the age of the patients. In one study, Chlamydia heat shock protein (HSP)-60 IgG ≥ 1:50 was associated with significantly increased odds of LC in two respective models (odds ratios of [95% confidence interval (CI) 1.06–1.69] and 1.30 [95% CI 1.02–1.67]). A fourth study reported C. pneumoniae IgA ≥ 64 titers to be 58%, 29%, and 5.5% among patients with LC, those without LC, and healthy blood donors, respectively. Conclusions: The incidence of LC was reported to range from 2.3% to 10.3% following an episode of pneumonia. There is limited evidence of the association of chronic Chlamydia infection with LC, and Chlamydia could be a causal cofactor of LC. causal cofactor of lung cancer. Metagenomic studies are needed to examine the changes in the lung microbiome triggering upregulation of the P13K signaling pathway.","PeriodicalId":91979,"journal":{"name":"The University of Louisville journal of respiratory infections","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48756497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Next generation sequencing (NGS) is poised to be the next powerful tool in standard clinical laboratories building on the widespread adoption of multiplex polymerase chain reaction (PCR) panels and matrix-assisted laser desorption/ionization-time of flight (MALDITOF) technology.[1] NGS can provide a quantitative analysis of all non-human DNA or RNA in a sample without requiring growth on a traditional medium. This improves the diagnostic yield of infections that are difficult to culture due to biofilm production, such as prosthetic joint infections.[2] As these technologies become faster and cheaper, research efforts are urgently needed to guide clinicians to wider applications of NGS, including use in non-sterile sites, such as lower and upper respiratory tract samples. The diagnostic utility of NGS of respiratory samples has already been noted in cases of pneumonia caused by pathogens that are difficult to identify through conventional testing.[3, 4] However, the use of NGS as a diagnostic tool in community-acquired pneumonia (CAP) remains to be elucidated. The characterization of the respiratory microbiome in clinical practice may improve the diagnosis and therefore the treatment of CAP. However, without adequate research, using NGS in patients with suspected CAP may unnecessarily accelerate antimicrobial prescribing simply by providing the names of all commensal organisms present in a respiratory sample.","PeriodicalId":91979,"journal":{"name":"The University of Louisville journal of respiratory infections","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79925983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This syndrome, known as post-acute sequelae of COVID-19 (PASC), can severely affect quality of life and represents an important health care concern. The exact causes for the symptoms observed in patients with PASC remain to be adequately characterized, but are likely to be associated with multiple factors, including residual disease and/or inflammation, organ damage, effects of hospitalization and/or prolonged ventilation, as well as effects of social isolation and stress.
