A Case Demonstration of the Open Health Natural Language Processing Toolkit From the National COVID-19 Cohort Collaborative and the Researching COVID to Enhance Recovery Programs for a Natural Language Processing System for COVID-19 or Postacute Sequelae of SARS CoV-2 Infection: Algorithm Development and Validation

A Case Demonstration of the Open Health Natural Language Processing Toolkit From the National COVID-19 Cohort Collaborative and the Researching COVID to Enhance Recovery Programs for a Natural Language Processing System for COVID-19 or Postacute Sequelae of SARS CoV-2 Infection: Algorithm Development and Validation

With regard to NLP usage in the context of PASC, rather than a focus on NLP algorithm development, NLP has primarily been used indirectly for other tasks within the PASC context. For instance, Bhavnani et al [46] extracted 20 signs or symptoms defined by the CDC as being PASC-related from clinical narratives to identify symptom-based phenotypes for patients with PASC, while Zhu et al [47] fine-tuned various BERT-based models to classify documents pertaining to patients with PASC signs or symptoms.

The Development of a Chatbot Technology to Disseminate Post–COVID-19 Information: Descriptive Implementation Study

The Development of a Chatbot Technology to Disseminate Post–COVID-19 Information: Descriptive Implementation Study

RAFAEL [26], an online information and exchange platform, was deployed by the Geneva University Hospitals [26] to address specifically the postacute sequelae of SARS-Co V-2 (PASC) or post–COVID-19 in children and adults. To date, RAFAEL [26] is an ecosystem including online information grouped by symptoms and themes, chatbot technology, and regularly scheduled webinars.

Peer Review of "Postacute Sequelae of COVID-19 and Adverse Psychiatric Outcomes: Protocol for an Etiology and Risk Systematic Review"

Peer Review of "Postacute Sequelae of COVID-19 and Adverse Psychiatric Outcomes: Protocol for an Etiology and Risk Systematic Review"

There is a more specific definition of PASC that should be included (with a reference). There is a need to list specific medical databases to search and not just mention “various” [1]. PECO criteria need to be listed and not only implied that they will be used. Do you have any other suggestions, feedback, or comments for the Author? The GRADE approach will be useful, as is mentioned along with a narrative synthesis if needed. Strengths and limitations seem accurate and are good to list.

Postacute Sequelae of COVID-19 and Adverse Psychiatric Outcomes: Protocol for an Etiology and Risk Systematic Review

Postacute Sequelae of COVID-19 and Adverse Psychiatric Outcomes: Protocol for an Etiology and Risk Systematic Review

Although sex and age are considered to be sociodemographic risk factors for PASC, there is no consensus on other baseline clinical features that act as independent predictors of PASC [9,10]. The prevalence of PASC symptoms is higher in women than in men [10]. Among people aged 35-49 years, the prevalence of PASC is 26.8% compared with 26.1% and 18% among people aged 50-69 years and 70 years or older, respectively [10].
