Background Helminth infection remains a health problem, especially in school-aged children. Mass eradication programs with a single dose of anti-helminthic drugs were employed by the local government in some endemic areas in Bali. However, the effectiveness of the programs has not been well evaluated.Objective To investigate prevalence and possible risk factors of helminth infection, including nutritional status, in elementary school students from endemic areas who participated in mass eradication programs.Methods This cross-sectional study involved 126 students from Elementary School No. 3 Gegelang, Karangasem, Bali, a location that had recently undergone a mass eradication program. Diagnoses were based on direct smear examination of fecal specimens. Information on suspected risk factors and nutritional status were collected by questionnaire and anthropometric measurement, respectively. Statistical analyses included Chi-square and odds ratio, using SPSS v21 software.Results The prevalence of helminth infection was 31.7% with etiologies of Trichuris trichuria (75%), Ascaris lumbricoides (17.5%), or both infections (7.5%). Habits of not using footwear [OR=4.88; 95%CI 1.15 to 20.65], not keeping nails trimmed [OR=3.33; 95%CI 1.07 to 10.37], and absence of a proper toilet [OR=4.31; 95%CI 1.93 to 9.64] were found to be significant risk factors for helminth infection. However, we found no significant association between helminth infection and nutritional status, although a considerable number of students had less than normal reference values, in terms of weight, height, and BMI for age.Conclusion The prevalence of helminth infection continues to be high, with personal hygiene and sanitation as significant risk factors. History of mass eradication programs did not confer an effective protection against helminth infection.
Summary Diabetes mellitus (DM) is still a challenging metabolic disease worldwide. In the current situation, the world is facing a COVID-19 pandemic due to SARS-CoV-2 infection. DM is one of the comorbid conditions that can worsen the severity of the COVID-19 condition. Surprisingly, SARS-CoV-2 infection can induce new-onset diabetes, a condition in which acute hyperglycemia occurs and may develop into a complication in nondiabetic patients. Angiotensinconverting enzyme 2 (ACE2) is a crucial entry factor for SARS-CoV-2 infection. ACE2 will bind to the spike protein of SARS-CoV-2, potentially initiating a damaging process in many tissues in the human body, including metabolic tissues. This mechanism suggests a potential role of ACE2 in the pathogenesis of diabetes since ACE2 has been proven to localize in essential metabolic tissues, one of which is the acini and islets part of the pancreas. This interrelated ACE2 in COVID-19 and DM is thought of as the mechanism that induces new-onset diabetes in COVID-19 patients. This review will thoroughly describe the current findings and theories regarding the molecular mechanism of SARS-CoV-2-induced new-onset diabetes and the possible therapeutic intervention.
Breast cancer stills remains as one of the major health problems in the world which ranks as the top cause of death of women with a percentage of 21.4%. There is connection of microRNAs (miRNA) with carcinogenesis process. miRNAs are small non coding RNAs (18 to 24 nucleotides) and formed as single-stranded RNAs (ssRNAs). The action of miRNAs is depended from their expression levels and function which can either promote oncogenesis (oncomiRs) or act as tumor suppressor pathways. One of the oncomiRs is miR-221 and miR-222, both are expressed by single transcription that are found on the X chromosome. The regulation transcription of miR-221/222 gene is control by positive and negative feedback. miR-221/222 directly targets PTEN, pro-apoptotic protein and tumor suppression gene, SOCS1 and CDKN1B in order to promote the proliferation of the cells. Â miR-221/222 enhances the aggressiveness of tumor through regulates the epithelial to mesenchymal transition (EMT) by targeting Tricho-rhino phalangeal syndrome type 1 (TRPS1) gene. miR-221/222 induces resistance of endocrine therapy in breast cancer especially tamoxifen and fulvestrant. The role of miR-221/222 in carcinogenesis is very complex that can upregulate or downregulate a protein. In addition, overexpression of miR-221/222 also enhances aggressiveness characteristics of breast cancer.Â
