Chromolaena odorata Linn leaf extract - Geothermal versus nongeothermal: Phytochemical, antioxidant, and cytotoxicity screenings.

Chromolaena odorata Linn, a popular yet underutilized ethnomedicinal plant, is hypothesized to possess higher bioactive phytoconstituents when it grows in geothermal areas. In this study, the comparison of ethanolic extract from geothermal and nongeothermal C. odorata leaves was carried out based on the phytochemical profile, antioxidant activity, and cytotoxicity. The leaf extracts were produced from a maceration using ethanol 96%, where the products were identified using reagents and gas chromatography-mass spectrometry (GC-MS). Antioxidant activities of both samples were measured based on their 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activities. Cytotoxicity was determined by brine shrimp lethality test using Artemia salina. Phenols were found to be more abundant in geothermal sample based on the qualitative screening and GC-MS analysis (i.e. higher relative abundance of phytol - 3.97%). DPPH antioxidant was higher in geothermal sample than in nongeothermal sample (median inhibitory concentration =13.04 ± 3.35 mg/L vs. 41.09 ± 4.13 mg/L, respectively). Geothermal sample was noncytotoxic (median lethal concentration [LC50] =2139.30 mg/L), whereas the nongeothermal sample had low cytotoxicity (LC50 = 491.48 mg/L). Taken altogether, geothermal C. odorata leaves contain higher bioactive compounds with potent antioxidant activities.

Gastrointestinal mucosal damages caused by ingestion of corrosive substances: A case study of hydrochloric acid and sodium hydroxide.

Ingestion of corrosive substances is most common in children, while in adults causes more severe damages. Massive ingestion of corrosive substances results in severe damage to the gastrointestinal tract and oropharynx if not treated properly. Corrosive substances with pH<2 or >12 can result in severe esophageal damage with either colliquative (alkaline) or coagulative (acidic) necrosis and, at the same time various gastrointestinal injuries could lead to late post-corrosive complications. The aim of the case study was to report the gastrointestinal mucosal damages due to hydrochloric acid (HCl) and sodium hydroxide (NaOH) ingestion. A 55-year-old male patient was presented to the emergency room with a chief complaint of vomiting an hour before admission. Continuous vomiting with a volume of approximately 10-20 cc per vomit. The vomit was initially bluish and turned in to blackish brown over time. Other complaints included nausea, rapid breathing, heartburn, and burning mouth and throat, and had weakness and dizziness. The patient accidentally drank floor cleaning liquid containing HCl. The patient was diagnosed with hematemesis due to ulceration of esophageal, gastric, and duodenal mucosa induced by HCl. Tracheoesophageal fistula developed later in the patient as a long-term complication. Another a 22-year-old male patient was presented to the emergency room with chief complaints of nausea and vomiting an hour before admission. Headache and slight tightness were also experienced. The patient mouth felt burned pain in the solar plexus and frothy saliva. An hour earlier, the patient attempted suicide by drinking two bottles of floor cleaning liquid due to economic problems. The patient was diagnosed with erosive mucosal esophagogastroduodenum induced by NaOH. These cases highlight that intoxication with corrosive substances can complicate damage to the gastrointestinal mucosal and damage features depend on the type of substance concentration and quantity of the corrosive substance.

Co-incidence of COVID-19 and hepatocellular carcinoma during pregnancy: Double punches to disease severity and mortality?

Hepatocellular carcinoma (HCC), a considerable leading cause of cancer-related deaths worldwide, is the most common primary liver cancer with poor prognosis and outcome. Many advances in prevention, screening, and new technologies in diagnostics and therapy have been achieved, but its incidence and mortality remain increasing. Co-infection of another viral disease in HCC patients with pregnancy might exacerbate the condition and double the mortality rate. The aim of this case report was to describe the co-infection of coronavirus disease 2019 (COVID-19) in an HCC patient during pregnancy. A 26-year-old woman with 16-17 weeks of gestation was admitted to Dr. Zainoel Abidin Hospital, Banda Aceh, Indonesia with shortness of breath. The patient also reported that the abdomen expanded rapidly in the last three weeks, followed by severe pain and collateral vein appearance. Laboratory findings revealed anemia, leukocytosis, HBsAg reactive, hypoalbuminemia, hyperbilirubinemia, elevated liver enzymes, increased alpha-fetoprotein (AFP), and cancer antigen 125 (CA-125). Ultrasonography indicated gestation with a single fetus, an enlarged liver with a 9.9 × 9.4 cm nodule, and massive ascites. The patient was also RT-PCR-confirmed COVID-19. On day 8 of hospitalization, the patient suddenly reported severe abdominal pain. Ultrasonography revealed fetal distress immediately followed by fetal death. Adequate management of cancer pain, continuous evacuation of ascites, and other supportive care could not save the patient who died on the day 17 of hospitalization. In this case, we found no proof that the patient experienced cirrhosis prior to HCC. Pregnancy through hormonal alteration is thought to be the aggravating factor that accelerates the progression of pre-existing liver disease into carcinoma and infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) worsened the outcome in this patient.

Serum pepsinogen level as a biomarker for atrophy, reflux esophagitis, and gastric cancer screening in Indonesia.

Background: Chronic dyspepsia's symptoms are frequently seen in primary to tertiary healthcare in Indonesia. This study aimed to describe the potential usability of pepsinogen (PG) values in determining gastric mucosal conditions, including superficial gastritis and atrophic gastritis. Materials and Methods: We recruited 646 adult dyspeptic patients and then analyzed PG values (including PGI, PGII, and PGI/II ratio) with endoscopic findings, gastric mucosal damages, and Helicobacter pylori infection. The gastric mucosal damage and H. pylori infection were evaluated using histological examination based on the updated Sydney system. Results: Among 646 enrolled patients, 308 (47.2%), 212 (32.8%), 91 (14.1%), 34 (5.2%), and 1 (0.2%) patient were diagnosed with normal mucosa, gastritis, reflux esophagitis, peptic ulcer disease, and gastric cancer, respectively. Significant differences in PGI, PGII, and PGI/II ratio values were observed among ethnic groups (all P < 0.01). The PGI and PGII levels were significantly higher and PGI/II was significantly lower in H. pylori-infected patients than in uninfected ones (all P < 0.001). The optimal cutoff value for PGII and PGI/II was 12.45 ng/mL with an area under the curve (AUC) value of 0.755 (0.702-0.811), sensitivity 59.3%, and specificity 77.1%; and 4.75 with AUC value of 0.821 (0.763-0.855), sensitivity 81.5%, and specificity 78.7%, respectively, to determine moderate-severe atrophy. Conclusion: Serum PG levels, a useful biomarker, represent the endoscopic findings, especially for reflux esophagitis. In addition, the benefits of PG values detecting atrophic gastritis were limited to moderate-severe atrophic gastritis. This usefulness requires careful attention for several ethnic groups in Indonesia.

Global prevalence of prolonged gastrointestinal symptoms in COVID-19 survivors and potential pathogenesis: A systematic review and meta-analysis.

Background: This study aimed to determine the cumulative prevalence of prolonged gastrointestinal (GI) symptoms, including nausea, vomiting, diarrhea, lack of appetite, abdominal pain, and dysgeusia, in survivors of both mild and severe COVID-19 worldwide and to discuss the potential pathogenesis.   Methods: Three databases (PubMed, Scopus, and Web of Science) were searched for relevant articles up to January 30, 2021. Data on study characteristics, clinical characteristics during follow-up, the number of patients with prolonged GI symptoms, and total number of COVID-19 survivors were retrieved according to PRISMA guidelines. The quality of eligible studies was assessed using the Newcastle-Ottawa scale. The pooled prevalence of specific prolonged GI symptoms was calculated and the association between COVID-19 severity and the occurrence of prolonged GI symptoms was assessed if appropriate.   Results: The global prevalence of prolonged nausea was 3.23% (95% CI: 0.54%-16.53%) among 527 COVID-19 survivors. Vomiting persisted in 93 of 2,238 COVID-19 survivors (3.19%, 95% CI: 1.62%-6.17%) and prolonged diarrhea was found in 34 of 1,073 survivors (4.12%, 95% CI: 1.07%-14.64%). A total of 156 patients among 2,238 COVID-19 survivors (4.41%, 95% CI: 1.91%-9.94%) complained of persistent decreased or loss of appetite. The cumulative prevalence of prolonged abdominal pain was 1.68% (95% CI: 0.84%-3.32%), whereas persistent dysgeusia was identified in 130 cases among 1,887 COVID-19 survivors (7.04%, 95% CI: 5.96%-8.30%). Data was insufficient to assess the relationship between COVID-19 severity and the occurrence of all prolonged GI symptoms.   Conclusion: Persistent GI symptoms among COVID-19 survivors after discharge or recovery raises a concern regarding the long-term impact of the COVID-19 infection on the quality of life of the survivors. Despite several potential explanations proposed, studies that aim to follow patients after recovery from COVID-19 and determine the pathogenesis of the prolonged symptoms of COVID-19 survivors are warranted.   PROSPERO registration: CRD42021239187.
