BACKGROUND: Active mucosal chronic otitis media (COM) is prevalent in lower-income countries and is associated with recurrent episodes of otorrhea due to chronic inflammation of the middle ear. Cytokines, which are well-known for their effects on the immune system, play an important role in the inflammatory response and tissue remodeling. The specific contributions of proinflammatory and immunoregulatory cytokines in the pathophysiology of active mucosal COM remain unclear. This study aimed to compare the levels of serum tumor necrosis factor (TNF)-α and transforming growth factor (TGF)-β in patients with active mucosal COM vs. healthy subjects.METHODS: Total 20 subjects with active mucosal COM and 20 healthy subjects participated in this study. The levels of serum TNF-α and TGF-β were measured using enzyme-linked immunosorbent assay (ELISA).RESULTS: The average level of serum TNF-α in subjects with active mucosal COM was significantly higher compare to the healthy subjects (46.373±41.76 pg/mL vs. 15.021±7.16 pg/mL; p=0.004). In contrast, the average level of serum TGF-β in subjects with active mucosal COM was lower compared to the healthy subjects, although the difference is not statistically significant (9.963±3.2 ng/mL vs. 11.78±8.48 ng/mL; p=0.552). Further analysis showed that in subjects with active mucosal COM, the levels of serum TNF-α had a medium positive correlation with the level of TGF-β (r=0.525; p=0.018).CONCLUSION: TNF-α and TGF-β, which are proinflammatory and immunoregulatory cytokines, may contribute to the pathogenesis of recurrent episodes of otorrhea in an active mucosal COM.KEYWORDS: tumor necrosis factor-α, transforming growth factor-β, active mucosal chronic otitis media

The battery is a storage medium for electrical energy for electronic devices developed effectively and efficiently. Sodium ion battery provide large-scale energy storage systems attributed to the natural existence of the sodium element on earth. The relatively inexpensive production costs and abundant sodium resources in nature make sodium ion batteries attractive to research. Currently, sodium ion batteries electrochemical performance is still less than lithium-ion batteries. The electrochemical performance of a sodium ion battery depends on the type of electrode material used in the manufacture of the batteries.. The main problem is to find a suitable electrode material with a high specific capacity and is stable. It is a struggle to increase the performance of sodium ion batteries. This literature study studied how to prepare high-performance sodium battery anodes through salt doping. The doping method is chosen to increase conductivity and electron transfer. Besides, this method still takes into account the factors of production costs and safety. The abundant coffee waste biomass in Indonesia was chosen as a precursor to preparing a sodium ion battery hard carbon anode to overcome environmental problems and increase the economic value of coffee grounds waste. Utilization of coffee grounds waste as hard carbon is an innovative solution to the accumulation of biomass waste and supports environmentally friendly renewable energy sources in Indonesia.

Background:The prevalence of autoimmune diseases and major chronic allergic diseases such as allergic rhinitis, asthma, and atopic dermatitis are increasing in line with the occurrence of climate change. Allergy and systemic lupus erythematosus (SLE) are sometimes being linked since both are immune diseases involving gene-environment interactions. The purpose of this research is to investigate the correlation between allergic diseases and SLE. Method: This case-control study was performed on 39 SLE subjects from the Tittari Community and 39 non-SLE subjects aged 15-49 years old, from September until October 2021. All of them were females. The independent variable was allergic disease and the dependent variable was SLE. Participants' characteristics and allergy data were collected through answering the online Score for Allergic Rhinitis (SFAR) questionnaire, then the results were processed with bivariate and multivariate analyses. Results:The correlation between allergic diseases and SLE was significant for atopic dermatitis but not for allergic rhinitis and asthma (p=0.018; p=0.352; p=0.151 respectively). The bivariate analysis revealed that the risk of SLE was 3.17 times higher in atopic dermatitis patients (OR=3.17; 95% CI=1.20-8.39; p=0.018). Furthermore, the multivariate analysis found that subjects with atopic dermatitis had the highest risk of SLE (OR= 3.18; 95% CI= 1.07-9.51; p=0.031). Conclusion: Among allergic diseases, atopic dermatitis was found to be significantly correlated with SLE, where the risk of SLE was raised as the number of atopic dermatitis increased.

Latar belakang: Bayi baru lahir dengan asfiksia perinatal dapat mengalami gangguan fungsi sel rambut luar  pada kokleanya. Tujuan:  Mengetahui   hubungan   asfiksia  perinatal  dengan  gangguan   fungsi  sel rambut luar koklea. Metode: Penelitian analitik observasional dengan desain Case control yang dilakukan di bagian perinatologi RSUD Dr. Moewardi Surakarta, RSUD Karanganyar,          RSUD Wonogiri, dan RSUD Sukoharjo dengan waktu penelitian  pada bulan Oktober 2014 – Januari 2015. Sampel penelitian dipilih dengan cara non probability sampling yaitu dengan teknik consecutive sampling, sebanyak 50 orang yang terdiri dari 25 kelompok kasus dan 25 kelompok kontrol. Diagnosis adanya gangguan fungsi sel rambut luar koklea  ditegakkan dari hasil pemeriksaan fisik THT dan pemeriksaan Distortion Product Otoacoustic Emissions  (DPOAE). Asfiksia perinatal dapat dilihat dengan menggunakan  skor APGAR, sedangkan faktor risiko yang lain dapat dilihat dari  catatan  medis pasien. Analisis statistik menggunakan univariat, bivariat, dengan chi square dan multivariat dengan regresi logistik ganda model faktor risiko. Hasil: Dari 25 kelompok kasus dan 25 kelompok kontrol didapatkan hasil bahwa asfiksia perinatal merupakan faktor risiko yang berpengaruh terjadinya gangguan fungsi sel rambut luar koklea.  Bayi baru lahir yang mempunyai  gangguan fungsi sel rambut luar koklea  dengan  asfiksia perinatal mempunyai faktor risiko 29 kali lebih besar daripada bayi dengan bayi baru lahir tanpa gangguan fungsi sel rambut luar koklea, setelah mengontrol pengaruh dari faktor perancu hiperbilirubinemia dan berat  badan lahir rendah. Hasil tersebut didapatkan bermakana secara statitistik (OR=29,614; CI – 95 % = 5,454 - 160,792; p<0,001). Kesimpulan: Terdapat hubungan antara asfiksia perinatal dengan  gangguan fungsi sel rambut luar koklea. Background: Newborn  with  perinatal  asphyxiae can occur disturbance of  function outer hair cell in the cochlea. Objective: was to know the relationship between the degree of perinatal asphyxiae  with impaired  function  of  outer hair cell. Methods: The study was  an analytic observational study with case control design, that  took a place in perinatology department in Doctor Moewardi hospital Surakarta, General hospital  in  Karanganyar,  General hospital in Wonogiri, General hospital in Sukoharjo. The study started from October 2014 until January 2015. The sample study were selected with consecutive sampling method, with total sample of 50 newborns which consist of 25 case group and 25 control group. Impaired function of outer hair cell  has been diagnosed from ENT examination and  examined with Distortion Product Otoacoustic Emissions  (DPOAE). Perinatal asphyxiae were measured with APGAR score and the other risk factor were collected from the medical record of the patients. Data were analyzed with univariat, bivariat (chi square) and multivariat statistic with double logistic regression. Result: From 25 case group and 25 control group, were found that perinatal asphyxiae was the influence risk factor to the occurrence of impaired function of outer hair cell. Newborns have impaired function  of  outer hair cell with   perinatal asphyxiae will have the risk of twenty nine times higher than newborns without perinatal asphyxiae, after controlling of confounding factors low birth weight, and hyperbilirubinemiae. The results  was statistically significant. (OR = 29,614; CI – 95 % = 5,454 - 160,792; p < 0,001). Conclusion: There has corellated between perinatal asphyxiae and impaired function of outer hair cell.
