Global Monkeypox Virus Outbreak 2022: A Bibliometric Analysis

Monkeypox is a rare zoonotic disease caused by the monkeypox virus, which spreads by direct contact mainly, thus having the propensity to cause future epidemics. The current review aimed to provide an up-to-date literature analysis for evaluating scientific data on monkeypox. A bibliometric analysis was conducted through eight electronic databases. The search period was from May 2022 to December 2023. All the articles were exported to Mendeley (Elsevier, Amsterdam, Netherlands). The literature search resulted in 415 relevant research articles. The growth of publications gradually rose, initiated in January 2022, leading to a rapid upsurge in May 2022. A total of 409 documents reported the number of citations, with two articles documenting the highest number, ranging from 146-150 and 216-220. The European region (EURO) dominated in publishing research articles on monkeypox, with the United States having the highest number of reports (n = 41; 9.87%), followed by the United Kingdom (n = 35; 8.43%) and Italy (n = 15; 3.61%). There were 82 funding agencies that funded 44 research articles, whereas 371 were not funded by any funding agency. Our analysis has presented the outline of the research articles published on monkeypox virus-related literature during the current outbreak. Research articles should be financially and administratively supported. Future research is required to expand research on the monkeypox virus, as there is a growing demand for original articles.

The First Case of Coxiella Burnetti Infection Detected Through Bone Marrow Biopsy in Vietnam

Coxiella burnetii is an obligate intracellular bacterium that causes the zoonotic infectious disease, Q fever. The common clinical presentation is fever, hepatitis, and pneumonia; laboratory examination could reveal pancytopenia, elevated liver enzymes. In bone marrow, many fibrin ring granulomas, also known as “Doughnut” granulomas can be seen and suggest the diagnosis of Q fever. However, these bone marrow granulomas can also be presented in infectious diseases by other pathogens such as EBV, CMV, and HBV; therefore, other serology or PCR—based tests are needed to confirm the diagnosis of Q fever. We report the first case of acute Q fever in Vietnam, presented as a fever of unknown origin with hepatitis in a 53-year-old male patient. A bone marrow biopsy was performed and showed various fibrin ring granulomas; therefore, Coxiella was suspected and the diagnosis was confirmed by PCR. Some infectious diseases can cause specific changes in the bone marrow, such as Doughnut granulomas in Q fever. These features can help direct the diagnosis and decide earlier treatment for the patient.

Factors Associated with Echinococcosis-Induced Perioperative Anaphylactic Shock

This retrospective case-control study explored the factors associated with anaphylactic shock during surgery for cystic echinococcosis (CE) at the First Affiliated Hospital of Xinjiang Medical University between October 2008 and September 2013. Patients who suffered from anaphylactic shock (n=16) were age-matched 3:1 to patients who did not (n=43). Multivariate analysis suggested that IL-4 levels (odds ratio=1.096; 95% confidence interval=1.015–1.185; P=0.02) and cyst size (odds ratio=3.028, 95% confidence interval=1.259–7.283, P=0.013) were independently associated with CE-induced perioperative anaphylactic shock. Using the receiver operating characteristic (ROC) curves and a cut-off value of 415.7 ng/ml, IL-4 showed an area under the ROC (AUC) of 0.926, sensitivity of 75.0%, and specificity of 97.7%. Using a cut-off value of 7.8 cm, cyst size showed an AUC of 0.828, sensitivity of 81.3%, and specificity of 76.7%. In conclusion, results suggest that levels of IL-4 and cyst size were independently associated with echinococcosis-induced perioperative anaphylactic shock. These results could help identifying patients with echinococcosis at risk of anaphylactic shock in whom appropriate prophylaxis could be undertaken.
