The coding of transcripts is a critical step for information extraction and preliminary analysis. However, manual coding is often labor-intensive and time-consuming. The emergence of generative artificial intelligence (GenAI), supported by Large Language Models (LLMs), presents new opportunities to understand human languages, which may significantly facilitate the coding process. This study aims to build a computational coding framework that uses GenAI to automatically detect and extract themes from in-depth interview transcripts.\u0000Methods: We conducted an experiment using transcripts of in-depth interviews with maternity care providers in South Carolina. We leveraged ChatGPT to perform two tasks automatically: (1) deductive coding, which involves applying a predefined set of codes to dialogues; and (2) inductive coding, which can generate codes from dialogues without any preconceptions or assumptions. We fine-tuned ChatGPT to understand the content of the interview transcripts, enabling it to detect and summarize codes. We then evaluated the performance of the proposed approach by comparing the codes generated by ChatGPT with those generated manually by human coders, involving human-in-the-loop evaluation. Results: The results demonstrated the potential of GenAI in detecting and summarizing codes from in-depth interview transcripts. ChatGPT could be utilized for both deductive and inductive coding processes. The overall accuracy of GenAI is higher than 80% and the codes it generated showed high positive associations with those generated manually. More impressively, GenAI reduced the time required for coding by 81%, demonstrating its efficiency compared to traditional methods.\u0000Discussion: GenAI models like ChatGPT show high generalizability, scalability and efficiency in handling large datasets, and are proficient in multi-level semantic structure identification. They demonstrate promising results in qualitative coding, making it a valuable tool for supporting people in public health research. However, challenges such as inaccuracy, systematic biases, and privacy concerns must be addressed when using them in practice. GenAI-based coding results should be handled with caution and reviewed by human coders to ensure accuracy and reliability.","PeriodicalId":501276,"journal":{"name":"medRxiv - Public and Global Health","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266512","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}

Objective- To evaluate the role of abnormal immune responses and risk factors such as advanced age, high parity, and presence of gestational diabetes in the pathogenesis of PPCM in Ethiopia. Method- A cross-sectional hospital-based study was conducted at Saint Paul Millennium Medical College (SPMCC) between January 2021 and January 2023. All female pregnant patients who were attending the Maternal Care Fetal Unit, Antenatal Unit, and High-Risk Unit at SPMMC were included in this study. However, among those patients, those mothers younger than 20 years old and older than 40 years old were excluded from the study. The total sample size collected from this facility was 250 patients. Results- Oxidative stress and inflammation were primarily correlated with pre-eclampsia and gestational diabetes. These risk factors were particularly prevalent within patients diagnosed with PPCM, 52.8% and 40% respectively. Prolactin Cleavage and Microvascular Dysfunction was associated with higher BMI and advanced age. With a general increasing trend observed in PPCM incidence and advancing age. As well as a high prevalence rate of PPCM in patients with Obesity Class I (at 33.0%). Another notable risk factor was high parity ( 45.0% with 4+ prior pregnancies). The most common symptom presented was dyspnea at 35.0%. The mortality rate was 14% whilst recurrence and the fully recovered ratio were at 13.1% and 34.0%, respectively. Conclusion- Results aligned with those conducted in other African countries (e.g. Zambia and South Africa) however mitigating high mortality as well as low full recovery rate will need to be done by earlier diagnosis, effective treatment, and intervention mechanisms.

Understanding public perception and practices taken to reduce vector abundance and vector-human contact can guide effective interventions that can mitigate health risks. Nevertheless, vector-borne disease surveys, which are widely used in the field to understand public perception and practices, are often inconsistent in terms of structure and implementation.\u0000This protocol is designed to provide guidance for public health professionals and researchers in the development of future KAP studies by ensuring uniformity in design and structure. This manuscript describes a rigorous three-phase protocol for the development of standardized vector-borne disease survey modules that can be used throughout the United States to generate data that are comparable across diverse regions. During phase one, a workshop with subject matter experts and a comprehensive literature review will be conducted to identify survey domains and generate items of interest. Survey items will also be mapped based on two theoretical frameworks, the Health Belief Model and the Risks, Attitudes, Norms, Abilities and Self-Regulation framework, to help gauge individual perceptions of risk severity and self-efficacy. During phase two, a group of expert judges will evaluate survey items based on content relevance, representativeness, and technical quality. During the final phase, cognitive interviews and surveys with target audience groups will be conducted to ensure the face validity of the modules. Participants will be drawn from a diverse range of educational and geographic locations, and computer-assisted personal interviewing will be implemented. The surveys developed through this protocol will be available to researchers aiming to gain deeper insights into the public's knowledge, attitudes, and practices concerning vector-borne diseases, facilitating the collection of more comparable data across various regions in the United States.","PeriodicalId":501276,"journal":{"name":"medRxiv - Public and Global Health","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266518","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}

However, interventions to limit such risk must balance public health protection, economic continuity, and individual rights. Here distinguishing between their role in disease introduction and its onward spread is crucial for achieving this balance. Methods: To investigate the role of haulage during the Delta wave of COVID-19 in Uganda. We fit a susceptible-infectious-recovered (SIR) model to the 625,422 records in the national surveillance dataset to assess the notion of a “core-risk group” by examining the incidence and impact of haulage-targeted interventions in border districts associated with heavy haulage traffic compared to the districts in the central region of Uganda. Results: Although haulage drivers accounted for only 0.036% of the cases, the border districts associated with them registered 12.02% more cases than inland districts, suggesting a role in disease introduction. This risk was particularly higher in Tororo, compared to Amuru and Kyotera, which border Kenya, South Sudan, and Tanzania, respectively. Some interventions even increased the risk in Tororo by as much as 6%. However, in general, the haulage targeted interventions reduced the case load in border districts but registered limited impact on inland districts. This suggests a limited role in secondary within country spread. We note that combining such interventions with vaccination achieved greater reduction in case load. Conclusions: Our findings suggest that truck drivers were a core risk group, though this risk was transient and in some cases exacerbated by some interventions. Pandemic preparedness strategies should characterize risks posed by core groups to ensure interventions balance public safety with individual rights in key sectors like supply chains.","PeriodicalId":501276,"journal":{"name":"medRxiv - Public and Global Health","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193560","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}

Dengue is caused by multiple antigenically different Dengue virus (DENV) serotypes (DENV-1 to DENV-4) in the Flaviviridae family and Chikungunya (CHIKV) in the Togaviridae family. Both viral diseases can produce similar clinical manifestations, especially in the early stages of infection which poses a significant challenge for timely diagnosis and improper disease management. Currently in India, diagnosis of Dengue and Chikungunya relies on ELISA-based tests, which often lead to false negatives and under estimation of the actual disease burden. The city of Bengaluru, in the state of Karnataka, in Southern India, witnesses spike in Dengue infection, and hence it is important to diagnose these arboviral infections early as well as accurately, to estimate the disease burden for precise epidemiological assessments. Methods\u0000A multiplex, quantitative, real-time PCR assay, DENCHIK was developed that can detect and differentiate between all four DENV serotypes and CHIKV infections simultaneously. Using DENCHIK assay, a total of 903 sera samples from suspected febrile patients were screened. The blood samples were collected across 161 public health centers, maternity homes and referral hospitals, in urban Bengaluru, between July 2022 - December 2022. The sensitivity and specificity of DENCHIK assay was compared with ELISA (NS1 antigen and Immunoglobulin M (IgM) antibodies) and two commercially available q RT-PCR assays for DENV and CHIKV. Findings\u0000Using DENCHIK assay, out of 903 samples, 36% infections were DENV, 17% CHIKV infections and 8% were coinfections with DENV-CHIKV. In contrast, ELISA detected 29.90% of DENV and 22.92% of CHIKV infections. We observed 9% prevalence of DENV infections using NS1 ELISA as compared to 24% as detected by IgM ELISA. DENV-1 was the predominant serotype followed by DENV-2, DENV-3 and DENV-4. There was an increase in the prevalence of DENV and CHIKV infections from June 2022 to September 2022, coinciding with the monsoon season. However, there was no significant difference observed in the prevalence of DENV and CHIKV infections across genders and age groups.\u0000The sensitivity and specificity of DENCHIK assay in DENV detection as compared to NS1 ELISA assay was observed to be 62.82% and 66.45%, respectively. In comparison to commercially available q RT-PCR assays for DENV detection, DENCHIK assay exhibited 99% and 98% sensitivity and specificity, respectively. Similarly, in case of CHIKV 26% sensitivity, 86% specificity and 98% sensitivity and specificity were observed, as compared to the IgM ELISA and commercial RT-PCR assays, respectively.

We reviewed the international evidence base to identify studies examining the impact of tobacco control polices on ITT.\u0000Methods: Guided by JBI scoping review methodology, we searched six databases (PubMed, CINAHL, EMBASE, PsycINFO, Scopus, and Web of Science) in 2022 and 2024 for original research published in English since 2000. One reviewer screened titles and abstracts, and two reviewers screened full-text articles against inclusion criteria.
