Effect of crude palm oil consumption on the levels of plasma ß-carotene, malondialdehyde and xanthine oxidase activity of healthy housewives
No full textCrude palm oil that contains high ß-carotenecan be obtained from mesocarp extraction of Elaesisguneensis Jacq.In the body, the ß-caroteneis converted to vitamin A that has antioxidant activity. Antioxidantscan inhibit lipid peroxidation induced by free radicals or singlet oxygen. It also inhibits the increase of reactive oxygen species (ROS) in the form of anion superoxide and hydrogen peroxide through the xanthine oxidase mechanism.This study aimed to evaluate the effect of crude palm oil consumption on the plasma ß-carotene and malondialdehyde (MDA) levels as well as xanthine oxidase activityof healthy housewives. Twenty-two healthy housewives who met the inclusion and exclusion criteria were involved in this study. Blood plasma samples were taken before and after consuming crude palm oil for two months as much as± 3.58 mL daily.The results showed that consumption of crude palm oil increased the plasma ß-carotene levels of 16 people (72%),and decreased the plasma MDAlevels of 13 people (59%).Meanwhile, thexantin oxidase enzyme activity showed no significantly different (p>0.05). Crude palm oil can increase plasma ß-carotene levels. It can be an alternative natural food source of provitamin A due to the high β-carotene content
Ischemic stroke in coronavirus disease 19 (COVID-19) positive patient: a case report
No full textA new coronavirus disease called COVID-19 was declared by World Health Organization (WHO). The COVID-19 may complicated into many other conditions, including neurologic. One among this neurologic complication is stroke. This paper aimed to report a case of ischemic stroke in COVID-19 positive patient in Yogyakarta, Indonesia. A male patient, 42 years old, came to emergency department with weakness in his right arm for two days as his main complain. He also had face drop on the right side, cough, and shortness of breath. He had a history of hyperthyroid and type II diabetes mellitus. The brain CT Scan showed a lacunar infarct in the left lentiform nucleus. Patient had nasopharynx and oropharynx swab to be checked for the presence of COVID-19 and the result was positive.The pathophysiology of stroke in COVID-19 include the hyperactivation of inflammatory factors that causes a fatal inflammatory storm. It also cause a damage of coagulation system which causing the D-dimer and platelet abnormalities, hypercoagulability from critical illness and cardioembolism from virus-related cardiac injury. Moreover, COVID-19 may cause a direct role in viral infection in central nervous system. In conclusion, ischemic stroke can be present along with COVID-19.
The risk of elevated plasma fibrinogen level in hypertensive and normotensive patientsafter bevacizumabintravitreal injection in diabetic retinopathy
No full textBevacizumab intravitreal injection (IVB) could be detected in plasma that might cause an imbalance in the coagulation system. A hypercoagulable state is potentially involved in the risk for thrombosis, which is associated with high cardiovascular mortality.The objective of the current study was to investigate the risk of elevated plasma fibrinogen levelsin hypertensive and normotensive patients after IVB in diabetic retinopathy. This study was conducted at Dr. Sardjito General Hospital, Yogyakarta from March to June 2019. A total of 64 patients were enrolled in the study, included of 32 hypertensive and 32 non-hypertensive patients with diabetic retinopathy who underwent IVB. Patients were interviewed and investigated for physical condition and opthalmological examination. Fibrinogen levelwas measured before and 1 week after IVB. The mean fibrinogen level beforeand after IVB was slightly high in hypertensive patients than normotensive but not significantly different(p>0.05). There was no significant risk of increased fibrinogen levels after IVB in the hypertension group compared to the normotension group in diabetic retinopathy patients. The proportion of patients at high risk for cardiovascular disease after IVB was not significantly different between both groups
Current understanding of the origin, molecular biology and continuing evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
No full textRecent outbreaks of human coronaviruses, officially named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have put health authorities worldwide on a high alert. Firstly emerged in the city of Wuhan, China, SARS-CoV-2 infection is rapidly escalating into a global pandemic. It is first thought as the result of a zoonotic transmission event, similar to the previous epidemic of coronaviruses. However, a continuously increasing number of confirmed cases indicates that the virus gains capacity of efficient human-to-human transmission. Soon after the pandemic is arising, many efforts are focused on identifying the origin of SARS-CoV-2 infection in the human population. Current evidence suggests that the virus is probably derived from bat or pangolin coronaviruses as the natural host. Whether intermediate host(s) exist in the transmission cascade from bat or pangolin to humans is, to a great extent, elusive. This information is essential as the basis for infection prevention and control measures. In this review, we discuss our recent understanding of SARS-CoV-2 biology, highlighting its origin and molecular evolution
Efficacy and safety of convalescent plasma therapy in patients with COVID-19: arapid review of case series
No full textCoronavirus disease 2019 (COVID-19) has become a world pandemic since early 2020.Currently, there is no established treatment to combat this potentially fatal disease. Convalescent plasma (CP) therapy has a strong scientific basis and historical perspective to treat previous viral infections such as Ebola, Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). The aim of this review was to evaluate the efficacy and safety of convalescent plasma CP therapy in patients with COVID-19.We searched for every available study from major databases (CENTRAL, MEDLINE via Ovid, EMBASE) through 20th April 2020. We independently screened, extracted, assessed the risk of bias, analyzed the data using SPSS version 26, and narratively summarized the data. For the outcomes, we wanted to evaluate the changes of clinical parameters, radiological appearance, pulmonary function, the titer of neutralizing antibody, viral load, the disappearance of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) RNA, and adverse events.We found five case series from our literature searching. The overall methodological quality of the case series was moderate. We included 27 patients, and all patients received CP transfusion. All patients experienced improvement of clinical symptoms and pulmonary lesions after receiving 200 to 2400 mL (median 200 mL) of CP transfusion. All patients in reported studies had negative results of reverse transcriptase-polymerase chain reaction(RT-PCR) after 1 to 26 days of transfusion (median 3 days). There was one non-life threatening adverse event reported after CP transfusion (facial red spot). In conclusion, CP therapy in COVID-19 patients showed promising results as it improved clinical symptoms and parameters, and it is well-tolerated based on our included studies. However, further expanded clinical trials with better designs are still required to evaluate the efficacy of this treatment although suchidea will be quite challenging to be conducted in the era of an epidemic
Histopathological changes and Hirschsprung’s associated enterocolitis (HAEC) scores
No full textHistopathological changes that are usually permanent in the bowel of Hirschsprung’s disease (HRSC) in children make susceptibility to the incidence of enterocolitis even after definitive therapy. The pathophysiology of HRSC is characterized by specific signs, and symptoms. Scoring system has been applied in diagnosis of Hirschsprung’s associated enterocolitis (HAEC) due to its simplest and easiest. However, after a decade it has been several evaluated to obtain optimal benefits in the clinical setting. The aim of this study was to investigate the relationship between histopathological grade of enterocolitis and HAEC scores. Children with HRSC who underwent leveling colostomy or pull-through were sampled from the ganglionic segment. Those with a histopathological description of HAEC were included in the study. HAEC scores were evaluated retrospectively through medical records and interviews. Data were analyzed using the Spearman’s Rank test. Twenty eight samples were involved in this study. The population was dominated by male (82.1%) and almost half the population (42.9%) were infants. The distribution of the histopathological grade was fairly even, except for grade V where it was only 7.2% of the total sample. Grade I & III samples were 21.4%, while grade II & IV were 25%, respectively. A significant relationship between histopathological grade and HAEC score was obtained (r = 0.927; p<0.0001). In conclusion, there is a relationship between the histopathological grade of enterocolitis and HAEC scores
Early hydroxychloroquine and azithromycin as combined therapy for COVID-19: a case series
No full textCoronavirus disease 2019 (COVID-19) is a worldwide outbreak caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The World Health Organization (WHO) has declared it as a public health emergency of international concern (PHEIC) and eventually a pandemic. Many clinical trials have been conducted to investigate potential and effective therapies for COVID-19. Here we reported the outcome of three COVID-19 cases treated early with the combination of hydroxychloroquine and azithromycin. Early treatments of suspected or confirmed positive COVID-19 cases with this combination therapy is to avoid disease progressions into a more severe and irreversible state. In these cases, clinical, radiological, and laboratory features were followed up. No complications were observed. The COVID-19 patients treated with this early combination therapy showed good clinical and virological responses
Effect of tagitinin C isolated from kembang bulan [Tithonia diversifolia (Hemsley) A. Gray] leaves on VEGF and TNF-α expressions ofkeloid fibroblast
No full textTagitinin C, an active constituent of Tithonia diversifolia (Hemsley) A. Gray, has been proven can inhibit the collagen deposition of keloid fibroblasts in vitro. However, its mechanism of action has not been widely studied. One possible mechanism involves growth factors and cytokines. Vascular endothelial growth factor (VEGF) and tumor necrosis factor alpha (TNF-α) play an important role in the collagen deposition. The study aimed to evaluate the effect of tagitinin C on VEGF and TNF-α expression in keloid fibroblasts culture. An experimental laboratory study using fibroblast cell lines at passages III and IV was performed. Treatments were divided into two groups i.e. the treatment groups after incubation with tagitinin C at various concentration of 1, 0.5, 0.25, and 0.125μg/ mL for 72 h, and the control group using culture media without tagitinin C. Following after incubation, the VEGF and TNF-α levels of keloid fibroblast culture supernatant were measured by ELISA. Kruskal-Wallis test continued using Mann-Whitney test or one way Anova continued by independent t test were applied to evaluate the differences between groups. A p value of less than 0.05 was considered statistically significant. The VEGF levels significantly decreases in concentration-dependent manner after treatment of the tagitinin C at various concentrations (p 0.05). In conclusion, tagitinin C decreases the VEGF expression of keloid fibroblasts. However, it has no effect on the TNF-α expression
A simple epidemic model of COVID-19 and its application to Ukrainian, Indonesian, and the global data
No full textAt the beginning of 2020, one of the most significant health problems for humanity is the pandemic of coronavirus disease 2019 (COVID-19). Here, we identify features and develop simple epidemic model of COVID-19 on the basis of available epidemiological data and existing trends worldwide. Modeling of COVID-19 epidemic process was based on a classic model. A key parameter of the model, i.e. transmission parameter of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was determined numerically with the use of available epidemiological daily reports of COVID-19 from 17 April to 23 May 2020. Numerical determination of transmission parameter of SARS-CoV-2 according to the absolute number of COVID-19 cases in Ukraine, Indonesia and worldwide data showed its global tendency to decrease over time. Approximation of the obtained numerical values of the transmission parameter of SARS-CoV-2 was carried out using the exponential function. The results of prognostic modeling showed that by the end of summer 2020, above 30 thousand COVID-19 cases are expected in Ukraine, 100 thousand COVID-19 cases in Indonesia, and 12 million COVID-19 cases worldwide. Thus, predicting the possible consequences of the implementation of various health care control programs COVID-19 involves a comprehensive study of the epidemic process of the disease as a whole and for certain periods of time with the subsequent construction of an adequate prediction model
Role of nuclear factor-κB (NF-κB) on mind body interventions (MBIs) in patients with systemic lupus erythematosus (SLE)
No full textMind body interventions (MBIs) are exercise that emphasizes the use of brain and body to assist the healing process and to manage symptoms in order to improve wellbeing. The MBIs are expected to be a supporting therapy for patients with autoimmune disease such as systemic lupus erythematosus (SLE), to improve patients’ activities, reduce fatigue, stress, and depression.One type of MBIs that could be potentially applied in Indonesia is latihan pasrah diri (LPD). Studies showed that MBIs can affect the expression of pro- and anti-inflammatory mediators. Nuclear factor-κB(NF-κB) is a transcription factor that controls gene expression related to many physiological responses including inflammation, proliferation, cell differentiation, and apoptosis. NF-κB can be activated through canonical and alternative pathway. This literature review aimed to identify the role of NF-κB as consequence of practicing MBIs in SLE patients. We searched for relevant publications in the MEDLINE/Pub Med and Google Scholar with no date restriction. This review revealed that abnormal NF-κB could mediate autoimmune condition in SLE pathogenesis. MBIs are expected to be a supportive treatment that can help to control NF-κB expression in SLE patients. LPD as an Indonesian original MBI is expected as a suitable techniques that can be applied in patients with SLE in Indonesia. Further studies on the effect of LPD on NF-κB expression in patients with SLE need to be further explored
