There has been limited analysis of the effects of hepatocellular carcinoma (HCC) on liver metabolism and circulating endogenous metabolites. Here, we report the findings of a plasma metabolomic investigation of HCC patients by ultraperformance liquid chromatography-electrospray ionization-quadrupole time-of-flight mass spectrometry (UPLC-ESI-QTOFMS), random forests machine learning algorithm, and multivariate data analysis. Control subjects included healthy individuals as well as patients with liver cirrhosis or acute myeloid leukemia. We found that HCC was associated with increased plasma levels of glycodeoxycholate, deoxycholate 3-sulfate, and bilirubin. Accurate mass measurement also indicated upregulation of biliverdin and the fetal bile acids 7α-hydroxy-3-oxochol-4-en-24-oic acid and 3-oxochol-4,6-dien-24-oic acid in HCC patients. A quantitative lipid profiling of patient plasma was also conducted by ultraperformance liquid chromatography-electrospray ionization-triple quadrupole mass spectrometry (UPLC-ESI-TQMS). By this method, we found that HCC was also associated with reduced levels of lysophosphocholines and in 4 of 20 patients with increased levels of lysophosphatidic acid [LPA(16:0)], where it correlated with plasma α-fetoprotein levels. Interestingly, when fatty acids were quantitatively profiled by gas chromatography-mass spectrometry (GC-MS), we found that lignoceric acid (24:0) and nervonic acid (24:1) were virtually absent from HCC plasma. Overall, this investigation illustrates the power of the new discovery technologies represented in the UPLC-ESI-QTOFMS platform combined with the targeted, quantitative platforms of UPLC-ESI-TQMS and GC-MS for conducting metabolomic investigations that can engender new insights into cancer pathobiology.

Aberrant lipid metabolism in hepatocellular carcinoma revealed by plasma metabolomics and lipid profiling.

Background: Several serum parameters have been evaluated for adding prognostic value to clinical scoring systems in diffuse large B-cell lymphoma (DLBCL), but none of the reports used multivariate testing of more than one parameter at a time. The goal of this study was to validate widely available serum parameters for their independent prognostic impact in the era of the National Comprehensive Cancer Network–International Prognostic Index (NCCN-IPI) score to determine which were the most useful. Patients and Methods: This retrospective bicenter analysis includes 515 unselected patients with DLBCL who were treated with rituximab and anthracycline-based chemoimmunotherapy between 2004 and January 2014. Results: Anemia, high C-reactive protein, and high bilirubin levels had an independent prognostic value for survival in multivariate analyses in addition to the NCCN-IPI, whereas neutrophil-to-lymphocyte ratio, high gammaglutamyl transferase levels, and platelets-to-lymphocyte ratio did not. Conclusions: In our cohort, we describe the most promising markers to improve the NCCN-IPI. Anemia and high C-reactive protein levels retain their power in multivariate testing even in the era of the NCCNIPI. The negative role of high bilirubin levels may be associated as a marker of liver function. Further studies are warranted to incorporate these markers into prognostic models and define their role opposite novel molecular markers. (J Natl Compr Canc Netw 2015;13:1501–1508)

Coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), was first reported in late 2019 from Wuhan, China. Considering COVID-19's alarming levels of spread and severity, the World Health Organization (WHO) declared a global pandemic on March 11, 2020. The first case of COVID-19 in Nepal was reported on January 23, 2020. The Government of Nepal implemented different public health measures to contain COVID-19, including border closures and a countrywide lockdown. We collected the daily data provided by the Ministry of Health and Population (MoHP) of the Government of Nepal and illustrated the early epidemiological characteristics of COVID-19 in Nepal. By May 31, 2020, 1,572 cases and eight deaths were reported in Nepal associated with COVID-19. The estimate of prevalence for COVID-19 among tested populations was 2.25% (95% CI: 2.15–2.37%) and case-fatality rate was 0.5%. The majority of the cases were young males (n = 1,454, 92%), with overall average age being 30.5 years (ranging from 2 months to 81 years) and were mostly asymptomatic. There were only five cases from three districts until the end of March, but cases surged from April and spread to 57 out of 77 districts of Nepal by the end of May 2020 despite the continuous lockdown. Most of these cases are from the southern plains of Nepal, bordering India. As the effect of COVID-19 is expected to persist longer, the Government of Nepal should make appropriate strategies for loosening lockdowns in a phase-wise manner while maintaining social distancing and personal hygiene and increasing its testing, tracking, and medical capacity.

To evaluate the liver function, splenomegaly and related factors in the newly diagnosed acute leukemia patients. One hundred of fifty eight acute leukemia patients admitted in our hospital from March 2003 to April 2006 were studied. The related factors such as peripheral WBC count, bone marrow blasts, peripheral blasts, sex, age, AML, ALL affecting the liver function and splenomegaly were evaluated. Sixty two (39.24%) patients presented with splenomegaly. Twelve (7.59%) patients presented with hepatomegaly. Serum ALT was elevated in 54 (34.17%) patients. Similarly, serum AST, GGT, ALP, and Direct bilirubin were elevated in 26 (16.45%), 32 (20.25%), 20 (12.65%), and 22 (13.92%) patients, respectively. Low serum albumin was found in 40 (25.31%) patients. PT was prolonged in 62 (39.24%) patients. Statistical study shows that there is a relation between high WBC counts and elevated serum ALT (P<0.05) and high WBC counts and splenomegaly (P<0.05). Acute leukemia patients with leukocytosis are more prone to develop abnormal liver function and splenomegaly.

INTRODUCTION: Coronavirus disease pandemic has affected large number of people globally and has continued to spread. Preparedness of individual nations and the hospitals is important to effectively deal with the surge of cases. We aimed to obtain nation wide data from Nepal, about hospital preparedness for COVID-19. METHODS: Online questionnaire was prepared in accordance with the Center for Disease Control recommendations to assess preparedness of hospitals for COVID-19. The questionnaire was circulated to the over 800 doctors across the nation, who are the life members of six medical societies. RESULTS: We obtained 131 completed responses from all seven provinces. Majority of respondents had anaesthesiology as the primary specialty. Only 52 (39.7%) participants mentioned that their hospital had policy to receive suspected or proven cases with COVID-19. Presence of isolation ward was mentioned by 83 (63.4%) respondents, with only 9 (6.9%)mentioning the presence of airborne isolation. Supply of personal protective equipment (PPE) was inadequate as per 124 (94.7%) respondents. Critical care services for COVID-19 patients were possible only in hospitals of 42 (32.1%)respondents. RT-polymerase chain reaction could be performed only in the hospital of 6 (4.6%) respondents. CONCLUSIONS: It is apparent that most of the hospitals are not well prepared for management of patients with COVID-19. Resource allocation and policy making should be aimed to enhance national preparedness for the pandemic.

Introduction: Community acquired pneumonia is one the frequent cause of hospital admissions. Whereas, hyponatremia is a common electrolyte abnormality in hospitalized patients and has been shown to be associated with considerable morbidity and mortality. We aim to studyt the association of hyponatremia with community acquired pneumonia in terms of morbidity and mortality.Methods: A prospective observational hospital based study was conducted in a hospital for a year. All patients with a diagnosis of community acquired pneumonia and admitted in medicine ward, were included. Patients with diarrhea, known Chronic Kidney Disease, Heart Failure, Cirrhosis of Liver, Malignancy, taking diuretics, chemical pneumonitis, interstitial pneumonias and other debilitating disease were excluded. Results: Among the 72 cases of CAP, 61% were females and 39% were males. The mean age of patients was 51.3 years, 22 (30.55%) patients had severe CAP. A total of 7 cases expired with an overall mortality of 13.7%. The mortality risk increased with increasing CURB-65 score; CURB-65 score 0, 0%; CURB-65 score 1, 0%; CURB-65 score 2, 0%; CURB-65 score 3, 10%; CURB-65 score 4, 33%; CURB-65 score 5, 100%. i.e higher the CURB-65 score, higher the death rate of CAP patients (p<0.05). Hyponatremia was a common occurrence at hospital admission with an incidence of 36.11%. Hyponatremia at hospital admission was also associated with a longer length of hospital stay in cured CAP patients. The mean length of hospital stay was 4.3 days.Conclusions: High CURB-65 scores and lower values of serum sodium at admission in patients of CAP are associated with adverse outcomes both in terms of mortality and longer length of hospital stay. CURB-65 score should be incorporated into assessment of CAP and sodium of the patients during admission. Keywords: CURB-65 score; hyponatremia; mortality. | PubMed

Hyponatremia in Patients with Community Acquired Pneumonia.

Introduction: The gut mucosa in portal hypertension is the seat of microcirculatory changes that compromise its integrity and increase its susceptibility to damage. The mucosal changes in portal hypertension may require pharmacological, directed endoscopic or portal decompressive therapy. The objective of the study is to find out various upper gastrointestinal tract endoscopic findings in patients of portal hypertension.Methods: A prospective, cross-sectional, observational study of sixty patients of portal hypertension was conducted from June to October 2009. The esophagus, stomach and upper duodenum was visualized for any changes, especially by taking the tip of the instrument close to the mucosa.Results: Out of total, 60, 47 (78.3%) cases were cirrhotic and 13 (21.7%) cases were non-cirrhotic portal hypertension. The most frequent upper GI endoscopic finding was esophageal varices 56 (98.3%) followed by gastropathy 49 (81.6%), gastric hyperemia 19 (31.6%), duodenal hyperemia and erosive gastritis 16 (26.6% in each) and gastric varices 12 (20%). Esophageal varices were equally prevalent among cirrhotic and non cirrhotic portal hypertensive patients, 46 out of 47 (97.9%) and 13 out of 13 (100%) respectively. Gastropathy was more prevalent in cirrhotic patients with 87.2% vs. 75% in NCPF followed by 40% in EHO. However, duodenal ulcers were seen only in EHO 12.5%. Erosive gastritis was more prevalent in EHO (75%) followed by NCPF (60%), however, it was less frequent in cirrhotic portal hypertension (14.8%).Conclusions: The most common upper GI endoscopic finding in portal hypertensive patients were found to be esophageal varices followed by gastropathy, peptic ulcer disease (gastric and duodenal hyperemia, chronic gastritis, erosive gastritis, gastric ulcer and duodenal ulcer)._______________________________________________________________________________________Keywords: gastrointestinal tract; portal hypertension; varices.

Introduction: Chronic Kidney Disease is a worldwide public health problem that affects millions of people from all racial and ethnic groups. Identification of a Chronic Kidney Disease is a major risk factor for cardiovascular morbidity and mortality and is attributed to hyperuricemia. Evidences show that high serum uric acid contribute directly to glomerulosclerosis, interstitial fibrosis and atherosclerosis that correction of hyperuricemia associated with Chronic Kidney Disease will slow the progression of chronic renal failure. 
Methods: A hospital based cross-sectional study on chronic kidney disease patients including 57 patients on conservative treatment attending Bir Hospital with diagnosis of chronic kidney disease was performed. Detailed clinical history, examination and investigations including uric acid were done. Chronic Kidney Disease staging was done according to estimated glomerular filtration rate estimated by Cockcroft-Gault equation. Prevalence rate of hyperuricemia in Chronic Kidney Disease and its stages were calculated and compared with each other.
Results: A total of 57 Chronic Kidney Disease cases were enrolled, with male to female ratio of 2:1 and mean age 51.63Â±17.75 years. Hyperuricemia was present in 55 (96.49%) of study population. Though prevalence of hyperuricemia increased with Chronic Kidney Disease stage, there was no significant difference in mean value of uric acid in different stages. Hyperuricemia and stages of Chronic Kidney Disease had negative correlation which was statistically significant.
Conclusions: Hyperuricemia is highly prevalent among Chronic Kidney Disease patients with conservative management. The severity of hyperuricemia increases as Chronic Kidney Disease stage progresses.
