Etiology and outcome of hemoptysis in Qatar, a high-resource country with a large expatriate population: A retrospective study

Tuberculosis research advances and future trends: A bibliometric knowledge mapping approach

The Gulf Cooperation Council (GCC) countries are more vulnerable to many transmissible diseases, including tuberculosis (TB). This study is to identify the scientific publications related to TB in the GCC countries using topic modeling and co-word analysis. A bibliometric analytic study. The R-package, VOSviewer software, IBM SPPS, and Scopus Analytics were used to analyze performance, hotspots, knowledge structure, thematic evolution, trend topics, and inter-gulf and international cooperation on TB in the past 30 years (1993-2022). A total of 1999 publications associated with research on GCC-TB were published. The annual growth rate of documents was 7.76%. Saudi Arabia is the most highly published, followed by the United Arab Emirates, Kuwait, Qatar, Oman, and Bahrain. The most-cited GC country is Kingdom Saudi Arabia, followed by Kuwait. One hundred sixty research institutions contributed to the dissemination of TB-related knowledge in the GCC, where the highest publishing organizations were King Saud University (Kingdom Saudi Arabia; n = 518). The number of publications related to TB is high in GCC Countries. The current tendencies indicated that GCC scholars are increasingly focused on deep learning, chest X-ray, molecular docking, comorbid covid-19, risk factors, and Mycobacterium bovis.

Etiology, diagnostic modalities, and short-term outcomes of hemoptysis-a retrospective cross-sectional study from a tertiary care center in Qatar

Background

Hemoptysis is a concerning symptom characterized by the expectoration of blood from the respiratory tract, which can range from mild to life-threatening. It can be caused by various underlying conditions. Accurate diagnosis is critical for effective management. The causes of hemoptysis can vary depending on geographic location and the population's composition. In this study, we aimed to examine the etiology, diagnostic methods, and short-term outcomes of hemoptysis in Qatar, focusing on data from Hamad General Hospital (HGH), which serves as a major tertiary care center in the country. Qatar has a diverse and dynamic population, primarily composed of expatriate workers, especially from South Asia. Previous data on hemoptysis in Qatar was collected between 1997 and 2007, when the population was considerably smaller and less diverse. Given the substantial growth in population and diversity since then, this study sought to provide updated information on the causes and outcomes of hemoptysis in the region.

Methods

This is a retrospective single center observational data review from the largest tertiary care center of Qatar, HGH. Patients who presented to HGH from 01/07/2015 to 30/06/2018 with hemoptysis were included in the study. Descriptive and summary statistics were described and analyzed using SPSS version 23.

Results

A total of 172 patients met the inclusion criteria. Most of the patients were male (74.4%) with a mean age of 37.9±16.4 years. South Asians (43.6%) accounted for the majority followed by Qatari nationals (20.3%). Mild hemoptysis was recorded in 89.5% of patients while only 3.5% had severe hemoptysis. The mean duration of hemoptysis was 1.72±0.72 days. The most common etiology was respiratory infection in 72.6% of the patients followed by tuberculosis (TB) and bronchiectasis 7% each. All patients were managed with observation or antimicrobials except two of the patients with severe hemoptysis who required bronchial artery embolization (BAE). There were no reports of recurrence of hemoptysis or deaths until hospital discharge.

Conclusions

Respiratory infection is the most common cause of hemoptysis at our center. Mild hemoptysis is the major presentation and the majority improved with conservative treatment.

Rodent-Related Zoonotic Pathogens at the Human-Animal-Environment Interface in Qatar: A Systematic Review and Meta-Analysis

Rodents are one of the most diversified terrestrial mammals, and they perform several beneficial activities in nature. These animals are also important as carriers of many pathogens with public health importance. The current systematic review was conducted to formulate a true depiction of rodent-related zoonoses in Qatar. Following systematic searches on PubMed, Scopus, Science Direct, and Web of Science and a screening process, a total of 94 published articles were selected and studied. The studied articles reported 23 rodent-related zoonotic pathogens that include nine bacterial, eleven parasitic, and three viral pathogens, from which the frequently reported pathogens were Mycobacterium tuberculosis (32 reports), Escherichia coli (23), and Salmonella spp. (16). The possible pathway of entry of the rodent-borne pathogens can be the land port, seaports, and airport of Qatar through carrier humans and animals, contaminated food, and agricultural products. The pathogens can be conserved internally by rodents, pets, and livestock; by agricultural production systems; and by food marketing chains. The overall estimated pooled prevalence of the pathogens among the human population was 4.27% (95%CI: 4.03–4.51%; p < 0.001) with significant heterogeneity (I² = 99.50%). The top three highest prevalent pathogens were M.tuberculosis (30.90%; 22.75–39.04%; p < 0.001; I² = 99.70%) followed by Toxoplasma gondii (21.93%; 6.23–37.61%; p < 0.001; I² = 99.30%) and hepatitis E virus (18.29%; 11.72–24.86%; p < 0.001; I² = 96.70%). However, there is a knowledge gap about the listed pathogens regarding the occurrence, transmission pathways, and rodent role in transmission dynamics at the human–animal–environment interface in Qatar. Further studies are required to explore the role of rodents in spreading zoonotic pathogens through the One Health framework, consisting of zoologists, ecologists, microbiologists, entomologists, veterinarians, and public health experts in this country.
