A Comprehensive Bibliometric Analysis of Research Trends About Congenital Toxoplasmosis.

Toxoplasma gondii is an obligate intracellular protozoon that infects approximately one-third of the human population. The parasite could transmit from mother to fetus in cases of acute infection during pregnancy and cause complications in the fetus. The bibliometric analysis is a popular research area that evaluates all the studies indexed in particular databases on a subject. This article puts forth bibliometric review of the literature on maternal and congenital toxoplasmosis research indexed in the Web of Science database between 1945 and 2024. VOS viewer, Web of Science and MS Office Excel 17 programs were used in the study. The results of the search showed 1476 publications. The countries that most contributed to the literature were France (n=306, 20.73%), the USA (n=229, 15.52%), and Brazil (n=146, 9.89%). The most cited country was also France (n=10271, 35.52%), followed by the USA (n=9113, 31.51%), and England (n=2611, 9.03%). The top three countries by number of citations per document were Denmark (44.88), the USA (39.79) and France (33.57). The five departments with the most publications are Pediatrics (20.26%), General Internal Medicine (18.16%), Infectious Diseases (16.8%), Obstetrics (14.57%), and Immunology (11.86%). Wallon M. (n=57), Peyron F. (n=49), Thulliez P. (n=36) and Vilena I. (n=36) were the leading authors in terms of contribution to the literature. The five most published journals were Pediatric Infectious Disease Journal (3.66%), Journal of Clinical Microbiology (2.78%), Lancet (2.3%), Presse Medicale (1.76%), and American Journal of Obstetrics and Gynecology (1.63%). France is one of the countries that pays the most attention to congenital toxoplasmosis and compatible with this, in our study, the country with the highest number of studies on congenital toxoplasmosis was France. It is thought that drawing more attention to this issue and conducting more studies in countries where the disease is common might yield successful results, as in France.

The relationship between HIV/AIDS and coronary heart disease: A bibliometric analysis.

Acquired immunodeficiency syndrome is a malignant infectious disease caused by the human immunodeficiency virus (HIV). HIV gradually destroys the body's immune system and weakens the body's ability to resist diseases. People living with HIV may have a higher incidence of coronary heart disease than people without HIV. A literature retrieval from January 1, 1993 to October 1, 2023 based on the Web of Science Core Collection database. CiteSpace6.2.R4, VOSviewer v1.6.19, and Microsoft Excel 2019 were utilized for analyzing the following terms: countries, institutions, authors, journals, references, and keywords. There were 1144 articles. The highest number of articles is in the USA, followed by Italy. University of California System, Harvard University, and Johns Hopkins University were the top 3 most productive institutions with publications in this field of research. Journal of Infectious Diseases ranked first with the highest publications (532 records), followed by Immunology (362 records), and Cardiac Cardiovascular Systems (242 records). Keyword co-occurrence analysis showed antiretroviral therapy, myocardial infarction, and protease inhibitors, etc. Keyword cluster analysis obtained 13 categories, which were roughly divided into 3 themes: (1) cardiovascular disease that has occurred or may occur; (2) HIV acquisitions that have occurred; (3) risk factors for cardiovascular disease. The article obtained the hotspots and trends and provided references for subsequent research. Based on the keyword citation burst detection analysis, we speculated that heart failure, risk, subclinical atherosclerosis, infection, and association were the research hotspots in recent years, which had a certain predictive effect on the future research direction.

A 32-year global analyses on dynamic trends and geospatial visualization of genital tuberculosis and female infertility: A scientometric study

IntroductionGenital tuberculosis (GT) is an infection that can affect the female reproductive system, including the uterus, cervix, and ovaries. ObjectiveTo perform a scientometric exploration to analyze the spatiotemporal trend, evolution, and emerging patterns of scholarly output on GT and female infertility. MethodsAn observational, descriptive, retrospective study employing a scientometric methodology was carried out. Metadata from scholarly articles spanning the years 1990–2022 were extracted from the Web of Science. The metadata from the chosen articles, totaling 172 manuscripts, were exported on May 17, 2023, in plain text format, which will allow the analysis and integration of the data in the software used. ResultsWe found at 111 sources and found 172 documents on tuberculosis and female infertility. We observed an average annual growth rate of 7.46 %, and the average age of the documents was 10.4 years. The dual overlay map showed the distribution of scientific publications on tuberculosis and female infertility. Journals on the left side of the map are cited mainly in the journals on the right. We found that Clinical Infectious Diseases and Lancet journals condensed patterns and trends in 1995, while the Indian Journal of Tuberculosis did so in 1996. Dheda K., Joubert JJ., and Wang Y. were the authors who had India, Iran, and China as their main affiliation, respectively, and they mainly published their studies in the "American Journal of Respiratory and Critical Care Medicine" and "Tropical Doctor," among others. ConclusionsThis bibliometric study examined different sources and found an average annual growth rate of 7.46 %. Each article received an average of 16.48 citations. Different collaborative networks between countries were observed. In addition, there was a steady growth in published research in the field of tuberculosis and female infertility.

Meta-analytic review on the impact of factors that affect performance of malaria rapid diagnostic test in Africa

Timely, accurate diagnosis and treatment has improved malaria case management. Malaria Rapid Diagnostic Test (mRDT) kits are largely used in malaria diagnosis. Their performance is compromised by factors related to gene deletions, parasite density, quality of the kit, poor storage conditions and end-user inefficiencies hence diagnosis gives either positive, negative, false negative (FN) or false positive (FP) which defines consequent management strategies. This review assessed reports on prevalence of the Plasmodium falciparum histidine rich protein 2/3 (Pfhrp2/3) gene deletions in malaria infected populations in Africa and the risk of mRDT failure to identify malaria positive cases. Preferred Reporting Items for Systematic Meta-Analysis (PRISMA) statement was used for data collection. Literature search was done using Google and Mendel search for data published in a malaria journal, Journal of infectious diseases, scientific reports, Annals of Ibadan postgraduate medicine, and BMC journals published between 2019 and 2023. Fifty eight reports were identified were screened and tested for eligibility. 
 Majority of studies described the consistent use of Pfhrp2/3 mRDT for malaria diagnosis in rural health facilities in Africa and nine reports met inclusion criteria for review. Five of them certified the world health organization’s sample criteria of ‘more than 350 sample’ to estimate the prevalence of Pfhrp2/3 gene deletions leading to declaration of false negative results of which one study posted FN outcome resulting from these deletions. Four out of nine studies did not meet this WHO criterion. This review affirmed presence of Pfhrp2/3 gene deletions challenges in Africa though other countries recorded the converse. Data was pooled using random effect models with Odds ratio and 95% confidence limit. The prevalence of the gene deletions was heterogeneous, ranging from 0% to 78.1%. The review found that an average prevalence of Pfhrp2/3 deletion as 26.2%. This was above the WHO standard recommended declaration value of 5%.; a factor that demonstrated setback to the use of mRDT in malaria endemic regions. Therefore alternative methods should be used where aspersions are cast on outcome of mRDT for 
 it will help improve malaria treatment, tracking and management.

Laboratory Diagnosis of Genital Tuberculosis: A Narrative Review

Genital tuberculosis is a leading cause of infertility in high tuberculosis burden countries like Bangladesh. Diagnosing this condition can be challenging due to the diverse ways it can present, which requires a physician to have a high level of suspicion. The fallopian tubes are mainly affected, and the endometrium in 50% of cases1. Diagnostic modalities usually include histopathology, microscopy, solid and liquid culture tests, Polymerase Chain Reaction (PCR) tests, immunohistochemistry tests, radiology imaging and laparoscopic and hysteroscopic procedures.

Microbiologists M.R. Sharipova and A.M. Mardanova are Talented Students and Teachers

The history of the formation and development of the microbiological discipline at the Imperial Kazan University began in the middle of the XIX century. Then the first attempts were made to control infectious processes in the Kazan province (cholera, influenza, smallpox). With the advent of the microscope, university researchers have gained a new opportunity to observe microorganisms. At the end of the 19th century, the issues of medical and general microbiology were widely discussed in the scientific community of the city. At the very beginning of the twentieth century, the Bacteriological Institute was opened at the Faculty of Medicine, which became the flagship of these studies. However, microbiological research began to develop at other faculties of Kazan University already under Soviet rule (the work of A.P. Ponomarev and his student S.I. Limanova-Kolosova). They mainly dealt with issues of ecological and geological microbiology. At the very beginning of the Great Patriotic War, the University Laboratory of Microbiology was headed by M.I. Belyaeva, who in 1969 achieved the opening of the Department of Microbiology as part of the Biology and Soil Faculty of Kazan State University named after V.I. Ulyanov-Lenin. She was the founder of a new modern direction — the study of enzymes of microorganisms. Her students, who later became professors, R.P. Naumova and I.B. Leshchinskaya, have already educated their talented followers. This article is devoted to a review of the scientific and pedagogical activities of professors M.R. Sharipova and A.M. Mardanova, employees of the Department of Microbiology of Kazan Federal University. Bangladesh Journal of Infectious Diseases, December 2023;10(2):104-109

Effect of Silymarin on Gentamicin Induced Nephrotoxicity in Rats

Background: As oxidative stress is an important factor in producing nephrotoxicity by a variety of drugs and chemicals; so, it may be assumed that agents having antioxidant property may protect the kidney from oxidative damage and can improve renal function. Objective: In the present study the ameliorative effect of silymarin was determined in a gentamicin-induced nephrotoxic model of rat. Methodology: This experimental animal study was carried out in the Department of Pharmacology at Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from January 2014 to January 2015 for a period of one year. In this study nephrotoxicity was induced by administering gentamicin (80 mg/kg/day for 7 days) intraperitoneally. Silymarin was administered (500 mg/kg/day for 14 days) orally concomitantly with gentamicin (7 days) and sacrificed on 15th day. To determine nephrotoxicity and amelioration of nephrotoxicity as well as the status of oxidative stress and lipid peroxidation; serum creatinine, serum urea, renal cortical reduced glutathione and malondialdehyde levels were estimated. Changes in renal architecture were estimated by histopathology of renal tissues. Results: Group (II) rats were injected gentamicin intraperitoneally for 7 days and sacrificed on 15th day showed significant (P< 0.001) increase of serum creatinine and urea level while there was significant (P< 0.001) reduction of renal cortical glutathione and increase (P< 0.001) in malondialdehyde concentration when compared to the control group (group I). This was supported by histological observations of H&E and PAS stained transverse section of renal cortex which suggested significant (P< 0.001) level of structural damage of renal cortex as evidenced from glomerular atrophy, tubular degeneration, presence of desquamated cellular debries and cast in the tubular lumen, mononuclear inflammatory cell infiltration. Statistically significant amelioration was observed in all the biochemical parameters which were supported by histology of renal cortex in silymarin treated group. Conclusion: The results from biochemical and histological observations of the present study indicate that silymarin was probably effective to ameliorate the signs of toxic damage to the renal cortex.

Innovative Approaches for Ecological Monitoring Disease Outbreaks Carried by Horseflies (Diptera, Tabanidae): A Systematic Review

Background: The spread and adaptation of horseflies to new habitats, driven by global climate change, threatens not only animal health but also human well-being. Objective: This article addresses the significant health risks posed by horseflies, which are known carriers of multiple pathogens causing up to 25 different infectious, parasitic, and viral diseases, including anthrax, tularemia, leptospirosis, and anaplasmosis. Methodology: The study provided an overview based on an extensive literature review from 1929 to 2022, analyzing both Russian and English publications. Results: The 2011 tularemia outbreak in Norway, linked to lemming population surges, and the higher susceptibility among men in Slovakia's annual tularemia cases highlight the role of animal reservoirs and gender in disease transmission. Leptospirosis, prevalent globally except in cold regions, is influenced by climate events, with significant public health impacts observed in various regions, including Russia and the Philippines following natural disasters. Anaplasmosis, transmitted by insects and ticks and more prevalent in warmer months, remains under-researched, with its rising threat exemplified by the growing ixodes tick population in Belarus. Conclusion: In conclusion, understanding the epidemiology and sources of these diseases, along with recognizing the environmental and anthropogenic factors that influence their transmission, is vital. The study underscores the importance of ongoing surveillance, research, and preventive measures to mitigate the impact of these infectious diseases on public health.

Conclusion: The top 100 most-cited studies provide an important insight into the historical developments of monkeypox. The authors should strengthen the recognition and management of monkeypox worldwide and strengthen research cooperation among scholars in order to better respond to the ongoing or future outbreak.

A plagiarism paperdemic: determining plagiarism among COVID-19 articles in infectious disease journals between 2020 and 2021

BackgroundThe COVID-19 pandemic has caused drastic changes in the publishing framework which allowed for the quick review and rapid publication of manuscripts in order to quickly share vital information about this new viral pandemic to the general public and scientists. Alarms have been raised for the potential for misconduct in COVID-19 research. The purpose of this study is to determine the presence of plagiarism in COVID-19 papers across infectious disease journals.MethodsCOVID-19 related research and review articles published in infectious disease journals were collected. Each manuscript was optimized and uploaded to Turnitin, which is a similarity checking tool. Similarity reports were manually checked for events of true plagiarism using an 80% threshold, performed via human judgment.ResultsIn this cross-sectional study, 41.61% (n = 129) of manuscripts were deemed plagiarized out of a total of 310 papers that were analyzed. Plagiarism was identified in 35.07% of reviews (n = 47), and 46.6% of original research (n = 82). Among the plagiarized papers, the median number of copied sentences was 3 IQR 4. The highest recorded similarity report was 60%, and the highest number of copied sentences was 85. The discussion section of these articles was the most problematic area, with the average number of copied sentences in that section being 6.25 ± 10.16. The average time to judge all manuscripts was 2.45 ± 3.09 min. Among all the plagiarized papers, 72.09% belonged to papers where the similarity report was ≤ 15% (n = 93). No significant differences were found with regards to plagiarism events among the quartiles.ConclusionsPlagiarism is prevalent in COVID-19 publications. All similarity reports should be supplemented with human judgment.

An Interesting Case Report on Calcaneal Tuberculosis as a Rare Presentation of Disseminated Tuberculosis

Despite the high prevalence rate of tuberculosis infection in Malaysia, calcaneal tuberculosis (TB) is rare. In this article, we present a case of a 53-year-old Malay female who initially presented with left calcaneal swelling for 3 months. Surgical drainage was performed and affected calcaneal was biopsied for histological examination which findings reported as consistent with tuberculosis infection. Further history revealed concomitant respiratory symptoms with the diagnosis of disseminated TB is supported by positive Mantoux test, detection of Acid-Fast bacilli in sputum and CT imaging showing lung and vertebral involvement. Anti-tuberculosis medication is the first line of treatment in calcaneal TB and surgery is usually reserved for patient with severe, intractable disease.

Nutritional status of under-5 Rohingya Children admitted for Diarrheal Diseases at Primary Health Centers in Cox’s Bazar District of Bangladesh

Background: One of the leading causes of mortality and morbidity in under-5 children is Diarrhea. Malnutrition, in association with the diarrheal disease, affect children negatively. On 2018, Bangladesh saw massive influx Rohingya people with almost 29% under-5 children. Objective: The purpose of the present study was to determine the prevalence of malnutrition among children admitted with acute diarrheal diseases at the Primary health Centers at Cox’s Bazar. Methodology: This cross-sectional study was conducted among the diarrhea affected under-5 Rohingya children who reported to primary health centers at cox’s bazar. The study was conducted from January to December 2018. Primary caregiver of 276 respondents were interviewed, their hospital records were reviewed. Data were collected by face-toface interview using a semi-structured questionnaire. Results: The majority (60.1%) of the participants were male. Only 2.9% of the participants reported passing of macroscopic blood in stool. Oral Rehydration Solution (ORS) was not taken by most of the participants (50.7%), prior to visit to the hospital. The mean (±SD) age was 18.54 (±12.44) months. Among the participants, 14.1% had severe underweight (<-3 WAZ score) and 27.2% had moderate underweight (-3 to <-2 WAZ score). No death was reported, and 97.1% were discharged with advice from the hospital. Statistically significant relationship was found between age of the participants and underweight (p<0.05) with a Moderate effect size (Φ=.21). Conclusion: The study findings would be helpful to identify the need for raising awareness among Rohingya caregiver and help healthcare providers to become more cautious in treating diarrheal patients.

Burden of Salmonella Typhi Isolated from Bloodstream Infection from 2015 to 2020: A Systematic Review and Meta-analysis

Background: Bangladesh is a major contributor to the global problem of typhoid fever, which is predominantly caused by Salmonella typhi. This is due to Bangladesh’s subpar healthcare standards, inadequate cleanliness standards, and inappropriate and excessive use of antibiotics. Objective: Salmonella typhi antibiotic resistance and the current situation of typhoid fever in Bangladesh were the subjects of this systematic review. Methodology: Finding publications about Salmonella typhi in Bangladesh published between 2015 and 2020 required searching Google Scholar, PubMed, and Bangladesh Journals Online with pertinent keywords. A predetermined set of criteria determined who would be included or excluded. Results: Initially,50 articles were retrieved. Using PRISMA flow chart 5 were selected for the study. Through forest plot, the overall effect size is found 0.28 which is represented by a diamond with confidence interval of 0.06 – 0.50. Since the confidence interval does not cross the threshold of no impact, the p value is 0.00. We can conclude that the overall effect is statistically significant. Microsoft excel was used to figure out the trend of antibiotic resistance. The effect size of an article was 0.08 (95%CI 0.05 – 0.11) and weighted 20.44%. Another study was reported with the effect size of 0.07 (95%CI 0.00 – 0.14) and weighted 20.07%. Conclusions: S. typhi was shown to be quite prevalent, and there were also significant surveillance and data gaps in the research’ methodological data.

Multi-drug Resistant Mannheimia hemolytica and Pasteurella multocida in Pneumonic Sheep in Bangladesh

Background: Pneumonia in sheep is a complicated multicausal disease which affects the respiratory system causing increased morbidity and herd mortality rate. The members of Pasteurellaceae family are one of the prime causes of bacterial pneumonia in ruminants. Once infected by these organisms, antimicrobial therapy becomes obligatory. In Bangladesh, causation of pneumonic pasteurellosis and their antibiogram is unknown in sheep which insists the veterinarians to choose empirical antimicrobial therapy. Objectives: This study was undertaken to identify multidrug resistant Pasteurella multocida and Mannheimia hemolytica in sheep suspected with pneumonia. Methodology: The samples of nasal swab and the lungs were collected aseptically. After overnight incubation in Brain Heart Infusion broth, the samples were streaked onto 5.0% sheep Blood Agar to obtain pure colony with characteristic features which were subjected to biochemical tests, polymerase chain reaction (PCR), and antibiogram study against eight antibiotics. Results: A total number of 140 samples were collected of which 120 nasal swabs and 20 lungs were collected aseptically. In total, 16.7% pneumonia cases in sheep were found to be caused by Pasteurella species. Out of 140 samples, 43.57% (61/140) were positive for Mannheimia hemolytica (68.85%) and 19.67% for Pasteurella multocida. The mixed infection by both organisms was 11.48%. The Mannheimia hemolytica (MH) was predominant in lungs (100.0%) and nasal swab samples (18.3%) than Pasteurella multocida (PM) which were 15% and 7.5% respectively. All the isolates were found to be multi-drug resistant where resistance against Penicillin and Ampicillin was 100% for all isolates. The resistance of Mannheimia hemolytica and Pasteurella multocida towards sulfonamide, ceftriaxone, oxytetracycline, gentamicin, and streptomycin were 63.33%, 49.44%, 44.44%. 16.67%, 11.11% and 78.22%, 45.46%, 45.45%, 36.36%, 27.27% respectively. Among all antibiotics tested, Chloramphenicol stands out to be the most effective one (100% sensitive). Conclusion: This study states the first molecular identification of Mannheimia hemolytica and Pasteurella multocida from sheep suspected with pneumonia in Bangladesh and their antibiogram pattern against commonly prescribed antimicrobials. Due to their commensalism nature and wide host coverage, these MDR pathogens warrant judicious use of antibiotics in small ruminants to reduce veterinary public health hazard.
