Renal abnormalities and its associated factors among school-aged children living in Schistosoma mansoni endemic communities in Northwestern Tanzania

MAPK/NF-κB signaling mediates atrazine-induced cardiorenal syndrome and antagonism of lycopene

Atrazine (ATZ) is the most prevalent herbicide that has been widely used in agriculture to control broadleaf weeds and improve crop yield and quality. The heavy use of ATZ has caused serious environmental pollution and toxicity to human health. Lycopene (LYC), is a carotenoid that exhibits numerous health benefits, such as prevention of cardiovascular diseases and nephropathy. However, it remains unclear that whether ATZ causes cardiorenal injury or even cardiorenal syndrome (CRS) and the beneficial role of LYC on it. To test this hypothesis, mice were treated with LYC and/or ATZ for 21 days by oral gavage. This study demonstrated that ATZ exposure caused cardiorenal morphological alterations, and several inflammatory cell infiltrations mediated by activating NF-κB signaling pathways. Interestingly, dysregulation of MAPK signaling pathways and MAPK phosphorylation caused by ATZ have been implicated in cardiorenal diseases. ATZ exposure up-regulated cardiac and renal injury associated biomarkers levels that suggested the occurrence of CRS. However, these all changes were reverted, and the phenomenon of CAR was disappeared by LYC co-treatment. Based on our findings, we postulated a novel mechanism to elucidate pesticide-induced CRS and indicated that LYC can be a preventive and therapeutic agent for treating CRS by targeting MAPK/NF-κB signaling pathways.

A meta-analysis of pregnancy outcomes in the diagnosis of isolated foetal renal parenchyma by prenatal ultrasonography

BACKGROUND

To effectively circumvent foetal structural abnormalities and serious newborn sequelae, antenatal ultrasound evaluation can support making an early diagnosis for potential prenatal management or the termination of pregnancy.

OBJECTIVE

This study systematically evaluated a meta-analysis of different pregnancy outcomes in the diagnosis of isolated foetal renal parenchymal echogenicity (IHEK) by prenatal ultrasonography.

METHODS

Two researchers conducted a literature search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The following databases were included in the search: China National Knowledge Infrastructure, Wanfang Medical Network, China Academic Journals Full-text Database, PubMed, Web Of Science and Springer Link; additional library websites were also included, and the search reviewed different pregnancies among patients with IHEK. The outcome indicators were the live birth rate, the incidence of polycystic renal dysplasia and the incidence of pregnancy termination/neonatal death. The meta-analysis was performed using the Stata/SE 12.0 software.

RESULTS

A total of 14 studies were included in the meta-analysis (total sample content, 1,115 cases). The combined effect size of prenatal ultrasound diagnosis of pregnancy termination/neonatal mortality in patients with IHEK was 0.289 (confidence interval (CI) 95%; range, 0.102-0.397). The combined effect size of the live birth rate of pregnancy outcomes was 0.742 (CI 95%; range, 0.634-0.850. The combined effect size of the polycystic kidney dysplasia rate was 0.066 (CI 95%; range, 0.030-0.102). The heterogeneity of all three results was > 50%; accordingly, a random-effects model was used.

CONCLUSION

The indications for eugenic labour should not be included in a prenatal ultrasound diagnosis of patients with IHEK. In the results of this meta-analysis, the live birth and polycystic dysplasia rates were optimistic in terms of pregnancy outcomes. Therefore, under the condition of excluding other unfavourable factors, it is necessary to A thorough technical inspection is required to make an accurate judgment.

Fulminant Hepatitis and Ulcerative Colitis: Case Report of Ethiopian Child with Schistosomiasis and Amebiasis Co-Infection

Background

Schistosomiasis is a neglected tropical disease (NTD) that affects around 200 million people worldwide, the majority of whom are children aged 5 to 15 years. It is one of the most significant public health problems in tropical and subtropical regions. Entamoeba histolytica infection is common in areas where schistosomiasis is endemic because Schistosoma mansoni infection can reduce the host's immune response, resulting in increased morbidity.

Case Presentation

This is the story of a 12-year-old male adolescent from the Guji zone of the Oromia regional state of Ethiopia who presented to Hawassa University Comprehensive Specialized Hospital (HUCSH) complaining of bloody diarrhea of 1 week associated with vomiting of ingested matter of 2 weeks. He also had history of fever, chills, rigors, arthralgia, and weight loss during a 2 weeks period. Further questioning revealed that he had previously swum in a pond and had a self-limited itchy skin condition. The family said that similar cases had occurred in their town that resolved with medications provided at a local health center.

Conclusion

Schistosomiasis and amebiasis are major public health issues, especially in impoverished areas. Schistosomiasis presents differently clinically depending on the phase and clinical form in which it manifests, making diagnosis and management challenging. As a result, it necessitates an integrated collaboration involving clinicians, pathologists, and public health professionals. We describe ulcerative colitis (UC) ascribed to schistosomiasis and amoebiasis coinfection, and fulminant hepatitis due to schistosomiasis. As there was no report of liver abscess on sonographic scanning, hepatitis may not be due to coinfection. This case will be an alert to clinicians and public health personnel who are striving for the ultimate eradication of schistosomiasis and also teaches us that treating co-infections of both is beyond just giving praziquantel and antiamebics.
