Abstract
Abstract
Background
Heparin administered after Coronary Artery Bypass Grafting (CABG) can cause Heparin induced thrombocytopenia (HIT) leading to bleeding or thromboembolic complications. Despite its low incidence, HIT can lead to increased morbidity and in-hospital mortality.
Purpose
To study the incidence and periprocedural outcomes of HIT in On-pump vs Off-pump CABG patients.
Methods
This is a retrospective observational study involving index hospitalizations for CABG between January 1 2016–December 31 2019 from the National Inpatient Sample, the largest all-payer public database of hospital care data in the United States. Our study population included discharged adult patients (≥18 years) hospitalised for CABG using ICD-10 codes (validated in previous studies). Confounders were adjusted using Multivariable Regression Analysis.
Results
During 2016–2019, there were 100,715 principal hospitalizations for On-pump and 25,956 for Off-pump CABG. Mean age was 74.6±13.2 years. The incidence of HIT in the On-pump cohort was 0.33% (n=333) and 0.33% (n=85) in the Off-pump cohort. The On-pump cohort had 76% (n=76,543) males, 24% (n=24172) females (p<0.0001) and the Off-pump cohort had 74.5% (n=19337) males, 24.5% (n=6359) females (p<0.001). The On-pump cohort had 78.2% Whites, 7.1% Blacks, 7.7% Hispanics, and 7% other races, while the Off-pump cohort had 76.9% Whites, 7.8% blacks, 8.9% Hispanics and 6.4% other races. A total of 42.9% hospitalizations in the On-pump cohort had a Charlson Comorbidity Index (CCI) of three or higher and it was 43.5% hospitalizations in the Off-pump cohort. In-hospital mortality in the On-pump cohort was 1.6% and 2% in the Off-pump cohort.
Compared to the non-HIT cohort, On-pump HIT cohort had more females (31.2% vs 24%, p=0.02), were older (mean age: 67.2 years vs 65.7 years; p=0.006), had higher CCI of three or higher (65.8% vs 42.8%, p<0.001), longer LOS (22.2 days vs 9.2 days, p<0.001) with higher in-hospital mortality (13.5% vs 1.5%, p<0.001). Multivariate regression analysis showed HIT cohort had higher odds of in-hospital mortality than non-HIT cohort (aOR: 8; 95% CI: 5.7, 11.2; p<0.001) after controlling for age, sex, race, hospital region and status, income, insurance status and CCI.
The Off-pump HIT cohort had similar incidence of females (26% vs 27%, p=0.710), were older (mean age: 68 years vs 65.8 years; p=0.045), had higher CCI of three or higher (65.9% vs 43.5%, p<0.001), had longer LOS (22.9 days vs 9.4 days, p<0.001) with higher in-hospital mortality (10.6% vs 2%, p<0.001) compared to the non-HIT cohort. Multivariate regression analysis showed HIT cohort had higher odds of in-hospital mortality than non-HIT cohort (aOR: 4.7; 95% CI: 2.3, 9.5; p<0.001) after controlling for age, sex, race, hospital region and status, income, insurance status and CCI.
Conclusion
Our study observed that in-hospital mortality in patients with HIT was significantly high compared to patients without HIT after undergoing On-pump or Off-pump CABG.

Abstract
Abstract
Background
Ventricular fibrillation (VF) is common in acute ST segment elevation myocardial infarction (STEMI) and is associated with increased in-hospital mortality rate.
Purpose
We sought to investigate the association between VF and artery involved in STEMI
Methods
This is a retrospective observational study of hospitalizations between January 1, 2016 and December 31, 2019, using the National Inpatient Sample (NIS), the largest all-payer public database of hospital care in the United States.
Results
A total of 138,201 patients were primarily hospitalized for STEMI from 2016 to 2019. Among them 12,318 had right coronary artery (RCA) lesions, 427 had left main (LM) lesions, 2381 had left circumflex (LCx) lesions and 12,765 had left anterior descending (LAD) lesions. Mean age of patients with VF and STEMI was 62 years and that with RCA (63 years), LM (65 years), LCx (62 years), LAD (60 years), p<0.001. Females were 30.5% (n=42,231) among all STEMI group and 29.8% (n=3672) RCA, 29% (n=124) LM, 27.4%(n=653) LCx and 28.6%(n=3645) LAD, p<0.001. In-hospital mortality for all patients with STEMI was 7.9%. The in-hospital mortality associated with STEMI there was 5%, 23.4%, 6.6%, 7.1%, (p<0.001) for RCA, LM, LCx and LAD respectively. The incidence of VF among all patients with STEMI was 8.3% (n=11425) and for LM, LAD, LCX, and RCA was 12.9%, 10.7%, 9.2% and 7.9% (p<0.001). Mean hospital length of stay for VF with RCA (6.2 days), LM (5.5 days), LCx (6.9 days) and LAD (7.4 days). After adjusting for age, gender, race, income, comorbidities, hospital teaching status, region and year, patients with STEMI who had VF had higher odds of mortality (aOR 6.4, 95% CI, 6.1 to 6.8; P<0.001). The highest likelihood of mortality observed in patients with VF who had and LCx STEMI (aOR 7.9, CI 95%, 5 to 12.4; p<0.001) followed by RCA STEMI (aOR 7.4, 95% CI 6 to 9.1; p<0.001), and LM STEMI (aOR 6.1, 95% 3.1 to 12; p<0.001).
Conclusion
Highest in-hospital mortality was observed in patients with STEMI who had VF in LCx, followed by RCA and LM. There was higher occurrence of VF in STEMI involving LM.

Abstract
Abstract
Background
Cardiac Amyloidosis is often misdiagnosed due to its non-specific presenting symptoms. There is a lack of evidence on the clinical outcomes in patients with cardiac amyloidosis undergoing transcatheter aortic valve replacement (TAVR).
Purpose
To study periprocedural outcomes in patients hospitalised primarily for TAVR with and without cardiac amyloidosis.
Methods
This is a retrospective observational study involving index hospitalizations for TAVR between January 1, 2016 to December 31, 2019 from the National Inpatient Sample (NIS), the largest all-payer public database of hospital care data in the United States. Our study sample included discharged adult patients (≥18 years) primarily hospitalised for TAVR using ICD-10 codes. Confounders were adjusted using multivariable regression analysis.
Results
During 2016–2019, there were 43270 principal hospitalizations (unweighted sample) identified for TAVR, among them 4999 patients had a history of cardiac amyloidosis. Mean age was 79.3±8.4 years. Among patients hospitalised for TAVR, 54.4% (n=23539) were males, 45.6% (n=19731) were females (p<0.001), 1.71% (n=740) developed cardiogenic shock, 1.53% (n=662) required mechanical ventilation with an in-hospital mortality of 1.3% (n=563). There were 87% Whites, 4.2% Blacks, 4.8% Hispanics, 1.3% Asians, and 2.7% were other races. A total of 23,819 (55.1%) hospitalizations had a Charlson Comorbidity Index (CCI) of three or higher.
After undergoing TAVR, compared to the non-cardiac amyloidosis cohort, the cardiac amyloidosis cohort had less females (27.8% vs 45.6%, p=0.01), had similar age (mean age: 80.2 vs 79.3; p=0.665), higher incidence of congestive heart failure (CHF) (100% vs 74%, p=0.012), higher mechanical ventilation requirement (11.1% vs 1.5%, p=0.001)) but with a similar length of hospital stay (3.9% vs 3.9%, p=0.99). Multivariate regression analysis revealed that TAVR in cardiac amyloidosis cohort did not significantly increase the odds of in-hospital mortality than the non-cardiac amyloidosis cohort (aOR: 5.2; 95% CI: 0.7, 38.3; p=0.103). However, females had higher odds of mortality post-TAVR compared to males (aOR: 1.45; 95% CI: 1.22, 1.73; p<0.001) after controlling for age, sex, race, regional hospital location, hospital bed capacity, income, and CCI. There is an increasing trend of index TAVR hospitalizations with cardiac amyloidosis with 109.4 per 100,000 hospitalizations in 2016, 139.7 per 100,000 in 2017, 157.5 per 100,000 in 2018, 201.4 per 100,000 in 2019 (p trend<0.001).
Conclusions
After TAVR, cardiac amyloidosis is associated with higher incidence of CHF increased need for mechanical ventilation, similar in-hospital mortality rate in comparison to non-cardiac amyloidosis cohort. There was an increasing trend in the index hospitalizations for TAVR with cardiac amyloidosis from 2016–2019.

Abstract
Abstract
Background
Association of cardiac amyloidosis (CA) with aortic stenosis (AS) is well known. There is limited data on the association of CA with other valvular heart diseases like aortic regurgitation (AR), mitral stenosis (MS), mitral regurgitation (MR), tricuspid stenosis (TS), tricuspid regurgitation (TR), pulmonary stenosis (PS) and regurgitation (PR).
Purpose
To assess the associations between valvular heart diseases and cardiac amyloidosis.
Methods
This is a retrospective observational study from hospitalizations between January 1, 2016, and December 31, 2019, using the National Inpatient Sample (NIS), the largest all-payer public database of hospital care data in the United States. We looked into associations between valvular heart diseases (VHD) and CA.
Results
From 2016 to 2019, a total of 4999 patients with a history of CA, 16,711 MS, 361,864 MR, 380,072 AS, 89,452 AR, 194 TS, 104,151 TR, 853 PS, 13,277 PR were identified. Compared to those without any history of CA, those with a history of CA had significantly higher associations with MR (6.4% vs 1.3%, p<0.001), AS (3.6% vs 1.3%, p<0.001), AR (1% vs 0.3%, p<0.001), TS (0.02% vs 0, p<0.033), TR (2.7% vs 0.4%, p<0.001), PR (0.4% vs 0.1%, p<0.001). Mean age of patients with history of CA in MS (73.7 years), MR (75.2 years), AS (81.4 years), AR (77.1 years), TS (82 years), TR (77.3 years), PR (78.1 years). Compared to males, females had higher incidence of MS (0.1% vs 0.03%, p<0.001) and lower incidence of AS (1.2% vs 1.6%, p<0.001) and AR (0.3% vs 0.4%, p<0.001).
Conclusion
There was a significantly higher association between CA and MR, AS, TR. Comparatively, patients with CA and MS were younger than those with other VHD.

Abstract
Abstract
Background
Cardiac amyloidosis (CA), a restrictive cardiomyopathy that leads to heart failure, is often under-diagnosed in its early-stages, leading to patients being diagnosed with it in advanced stages. Most patients presenting with heart failure are presumed as non-amyloid heart failure due to a lack of awareness. A high degree of clinical suspicion is of paramount importance for early diagnosis and management of CA because the extent of cardiac involvement determines overall prognosis.
Purpose
Our study highlights the outcomes of HFpEF in patients with and without CA.
Methods
This is a retrospective cohort study involving principal hospitalizations for HFpEF between January 1, 2016 and December 31, 2019 from the National Inpatient Sample (NIS), the largest all-payer public database of hospital care data in the United States. Our study sample included discharged adult patients (≥18 years) hospitalised for HFpEF using ICD-10 codes validated in previous studies. Confounders were adjusted using multivariable regression analysis.
Results
During the study period, there were 87,219 index hospitalizations for HFpEF. Among them, 38.3% (n=33405) were males, 61.7% (n=53814) were females, and 0.24% (n=209) had CA. Racial distribution is as follows: 76% Whites, 13.4% Blacks, 6.4% Hispanics, and 4.2% other races. Mean patient age was 74.6±13.2 years, and 68.1% were on Medicare. A total of 59,135 (67.8%) hospitalizations had a Charlson Comorbidity Index (CCI) of >3, with an in-hospital mortality of 2.5%. Compared to the non-CA cohort, the CA cohort had lower prevalence of diabetes mellitus (8.5% vs 27%, p<0.0001) and COPD (23.5% vs 46.8%, p<0.001) but a higher prevalence of renal disease (51.6% vs 41.9%, p=0.004), cancer (25.4% vs 4.2%, p<0.001) and greater incidence of cardiogenic shock (5.2% vs 0.5%, p<0.001).
Compared to the non-CA cohort, patients with CA were less likely to be female (38% vs 61.7%, p<0.001), were of similar age (mean age 74.7 vs 74.6 yrs, p=0.907), had longer length of hospital stay (LOS, 6.7 vs 5.1 days, p<0.001), higher in-hospital mortality (5.2% vs 2.5%, p=0.023), and a higher likelihood of having a CCI >3 (74.2% vs 67.8%, p=0.017). Multivariate regression analysis showed that subjects in the CA cohort had significantly increased adjusted odds of in-hospital mortality (aOR=2.2; 95% CI: 1.2–4.4; p=0.017) and cardiogenic shock (aOR=9.5; 95% CI: 5–17.9; p<0.001) than those in the non-CA cohort after adjusting for age, sex, race, and CCI.
Conclusions
Our study illustrates that patients with a history of CA admitted for HFpEF had greater incidence of cardiogenic shock, higher prevalence of renal diseases and cancer with a longer LOS, and higher in-hospital mortality.

Abstract
The global pandemic due to coronavirus disease 2019 (COVID-19) has posed an overall threat to modern medicine. The course of the disease is uncertain with varying forms of presentation that cannot be managed solely with clinical skills and vigor. Since its inception, laboratory medicine forms a backbone for the proper diagnosis, treatment, monitoring, and prediction of the severity of the disease. Clinical biochemistry, an integral component of laboratory medicine, has been an unsung hero in the disease prognosis and severity assessment in COVID-19. This review attempts to highlight the biomarkers which have shown a significant role and can be used in the identification, stratification, and prediction of disease severity in COVID-19 patients. It also highlights the basis of the use of these biomarkers in the disease course and their implications.

Abstract
Iodine deficiency during childhood affects physical and mental development. Iodine deficiency or excess both can negatively impact thyroid function. We conducted this study to assess iodine nutrition and thyroid function in children with insufficient urinary iodine concentration. A community-based cross-sectional study was conducted among the selected schools of Udayapur district. Urinary iodine concentration (UIC) was measured in 1012 school children (6-14 years). Based on UIC data, 83 blood samples were collected to measure serum thyroglobulin (Tg), thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), and free thyroxine (fT4). UIC was measured by ammonium persulfate digestion method, and Tg, TSH, fT4, and fT3 were measured using ELISA kits. The median UIE was 236 µg/L, and 11.1% of the children had insufficient UIC. The mean fT3, fT4, and TSH in children with insufficient UIC were 2.55±0.43 pg/mL, 0.96±0.28 ng/dL, and 3.60±1.44 mIU/L respectively. Among children with low UIC levels, the median Tg was 17.5 ng/mL. Overt hypothyroidism was seen in 6%, and subclinical hypothyroidism in 3.6%. The children had sufficient iodine nutrition, and the frequency of thyroid dysfunction was low among the children with insufficient UIC.

Abstract
Background Aberrant iodine intake and thyroid autoimmunity affect thyroid function. Deficiencies of iodine including thyroid disorders have serious impact on child physical and mental development. This study was conducted to investigate iodine nutrition, thyroid function and thyroid autoimmunity in the Nepalese children, and explore the association of thyroidal autoimmunity with iodine nutrition and thyroid dysfunction. Methods Five schools from Udayapur district of eastern Nepal were selected for the study. A total of 213 school children aged 6–12 years were enrolled, and anthropometric data, urine samples and blood samples were collected. Urinary iodine concentration (UIC), free triiodothyronine (fT3), free thyroxine (fT4), thyroid stimulating hormone (TSH), and antithyroglobulin antibody (TgAb) was measured. Independent T test, Man-Whitney test, Chi-square test and Fisher’s Exact test were used for testing statistical significance. Spearman’s correlation analysis was done to find association between variables. Results The median UIC with IQR, mean ± SD fT3, mean ± SD fT4, median TSH and TgAb with IQR was 150.0 μg/L (102.8; 204.0), 2.49 ± 0.83 pg/ml, 1.33 ± 0.42 ng/dl, 2.49 mIU/L (1.58; 4.29), and 21.40 IU/ml (15.54; 31.20) respectively. Elvated TgAb (≥30 IU/ml, thyroid autoimmune condition) was seen in 25.8% (n = 55) children. UIC was less than 100 μg/L in 17.4% (n = 37) of the children. Subclinical hypothyroidism, overt hypothyroidism and sublinical hyperthyroidism was seen in 1.4% (n = 3), 3.3% (n = 7) and 3.8% (n = 8) children respectively. A strong association of TgAb with UIC (r = − 0.210, p = 0.002) and thyroid hormones; fT3 (r = − 0.160, p = 0.019), fT4 (r = − 0.275, p < 0.001), and TSH (r = 0.296, p < 0.001) was seen. The relative risk for thyroid autoimmunity in children with UIC less than 100 μg/L was 1.784 (95% CI: 1.108–2.871, p = 0.024). Similarly, children with thyroid autoimmunity had higher relative risk [7.469 (95% CI: 2.790–19.995, p < 0.001)] for thyroid dysfunction. Conclusions School children of eastern Nepal have adequate iodine nutrition. Thyroid autoimmunity is very common, while thyroid dysfunction is sparse in children. An association of thyroid autoimmunity with iodine nutrition and thyroid dysfunction was seen in children.

Abstract
Objectives Deficiency as well as excess dietary iodine is associated with several thyroid disorders including Grave’s disease and goitre. Previously, cross sectional studies conducted among school children in Nepal showed high prevalence of iodine deficiency. In contrast, recently, few studies have revealed emerging trends of excess urinary iodine concentration in children. This paper, reports excess urinary iodine excretion and thyroid dysfunction among school age children from eastern Nepal. Results It was a community based cross sectional study in which we measured urinary iodine excretion levels among school age children at baseline and after educational program. The educational program consisted of audio-visual and pamphlets on thyroid health. We also screened them for thyroid function status by physical examination and measuring serum thyroid hormones. Our results show that 34.4% of the children had excess urinary iodine concentration above the WHO recommended levels. Overall, 3.2% of the children were identified to have thyroid dysfunction. Urinary iodine concentration was significantly different between types of salt used and between salt iodine content categories.

Abstract
The hyperuricaemia in Gestational diabetes mellitus has been explained to be a component of the metabolic syndrome which reflects insulin resistance and it has been shown to have a positive correlation with the creatinine levels. Gestational hyperuricaemia was found to be significantly associated with a high rate of maternal and foetal complications along with proteinuria and hypertension. Aimed of this study was to evaluate the serum creatinine and uric acid levels in Bangladeshi women with GDM in their second and third trimester of pregnancy. This descriptive cross sectional study was conducted at Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from July 2013 to June 2014. Pregnant women, in their second and third trimester, attending the outpatient department of Obstetrics and Gynecology and the Department of Endocrinology, MMCH, Mymensingh, Bangladesh were enrolled by purposive sampling technique. GDM was diagnosed on the basis of oral glucose tolerance test (OGTT) as outlined in UN agency WHO criteria 2013. Out of 172 participants, 86 had GDM (Case) and 86 were normoglycemic (control). The mean age of GDM and control groups was 28.6±3.2 and 27.3±3.1 years respectively. The BMI was 26.4±1.5 kg/m² and 26.3±1.3 kg/m². In this study we found serum creatinine levels in GDM cases were significantly (p<0.001) increased in both trimesters (1.09±0.16mg/dl and 1.07±0.11mg/dl) compared to those without GDM (0.69±0.16mg/dl and 0.64±0.15mg/dl). Serum uric acid levels in GDM and without GDM in 2nd trimester were (4.47±0.42mg/dl and 4.43±0.63mg/dl respectively) had (p>0.05) no significant difference. Serum uric acid levels in GDM cases were significantly (p<0.001) higher in third trimesters (4.48±0.41mg/dl) compared to those without GDM (3.52±0.74mg/dl). There was distinct alteration of serum creatinine and uric acid levels in GDM compared to normal pregnancy.

Abstract
Background: Iron deficiency is the most common nutritional deficiency in the world. The relation between thyroid hormones and iron status is bidirectional. The aim of this study was to assess iron nutrition status and evaluate its relationship with thyroid hormone profile among children of Eastern Nepal.
Methods: A community based cross-sectional study was conducted in eastern Nepal. A total of 200 school children aged 6-12 years were recruited after taking informed consent from their guardians. Blood samples were collected and assayed for free thyroid hormones (fT3 and fT4), thyroid stimulating hormone (TSH), serum iron, total iron binding capacity (TIBC) concentration and percentage transferrin saturation was calculated.
Results: The mean serum iron and TIBC was 74.04 µg/dl and 389.38 µg/dl respectively. The median transferring saturation was 19.21%. The overall prevalence of iron deficiency (Transferrin saturation < 16%) was 34% (n=68). The mean concentration of fT3 and fT4 was 2.87 pg/ml and 1.21 ng/dl respectively, while the median TSH concentration was 3.03 mIU/L. Median TSH concentration in iron deficient group (3.11 µg/dl) and iron sufficient group (2.91 µg/dl) was not significantly different. Among iron deficient children 5.9% had subclinical hypothyroidism (n=4). Iron status indicators were not significantly correlated with thyroid profile parameters in the study population.
Conclusions: The prevalence of iron deficiency is high and iron deficiency does not significantly alter the thyroid hormone profile in the study region.

Abstract
OBJECTIVE Pan Masala containing Tobacco (PMT) use contributes significantly to the overall world tobacco burden especially in south Asian country like Nepal. Oxidative stress caused by it may leads to cardiovascular disease, peripheral vascular disease, hypertension, etc. Therefore, this work proposes to study the antioxidant and oxidative stress along with cardiovascular morbidity in PMT users. RESULTS Hundred PMT users and 80 non-user controls with age and sex matched were enrolled. There was a significant difference in blood pressure, albumin, uric acid, vitamin C, vitamin E, malondialdehyde (MDA), total cholesterol, triglycerides, low density lipoprotein cholesterol between the two groups (p < 0.001). We observed statistically significant (p < 0.001) decrease in antioxidant and increase oxidative stress in PMT users. Duration and quantity of PMT user were significantly associated with the MDA level.

Abstract
BACKGROUND Psoriasis is a dermatological disorder with a multifactorial origin and is associated with many biochemical and immunological changes. PURPOSE This study aimed to examine the association of serum ADA activity, uric acid (UA), and high-sensitivity CRP (hs-CRP) with psoriasis and the role of ADA in disease severity. MATERIALS AND METHODS In this comparative cross-sectional study, 50 clinically and histopathologically diagnosed psoriasis patients and 50 age- and sex-matched healthy controls were enrolled. Blood samples were taken and analysis of the biochemical parameters was performed according to Giuisti and Galanti method, uricase and ELISA technique for ADA activity, UA, and hs-CRP, respectively. The severity of the disease was scored according to Psoriasis Area and Severity Index (PASI). Statistical analysis of differences within and between the study groups was carried out using the Student's t-test, one-way post hoc ANOVA, and Pearson's correlation. Linear regression was used to establish the independent association of ADA with disease severity. RESULTS The serum ADA activity, UA, and hs-CRP levels of the psoriatic patients were found to be significantly higher (P<0.001). hs-CRP was positively correlated with ADA and UA in patients (P<0.001). There was no significant difference in total cholesterol, low-density lipoprotein, and triacylglycerol in psoriasis patients, whereas we noted a decreased high-density lipoprotein level in psoriasis patients as compared to controls. Linear regression showed that ADA was independently associated with the disease severity and was statistically significant (P<0.001). CONCLUSION ADA activity was positively and significantly associated with the severity of psoriasis, therefore, it could be suggested as a marker for disease severity in psoriasis patients.

Abstract
BACKGROUND Diabetes mellitus is a group of metabolic disorders of carbohydrate metabolism in which glucose is underused, producing hyperglycemia. Diabetic patients are prone to opportunistic infection, thus serum ADA levels in these patients is very important as a screening test for Tuberculosis and autoimmune diseases. Thus, the present study was conducted to estimate the Serum ADA activity, glycated Haemoglobin (HbA1c), fasting and postprandial glucose level in patients with T2DM and to correlate the serum level of ADA with glycated Hemoglobin (HbA1c), fasting and postprandial glucose level in T2DM. METHODS This is a Hospital based cross-sectional study done in BPKIHs, Dharan, Nepal. 204 diagnosed patients (102 males and 102 females) with T2DM and 102 healthy controls were enrolled in the study. Diabetic patients were categorized into Uncontrolled and Controlled Diabetes on the basis of HbA1C; HbA1c > 7% = Uncontrolled Diabetes, HbA1c < 7% = Controlled Diabetes. RESULTS Serum ADA levels (U/L) was significantly raised in Uncontrolled Diabetic patients (49.24 ± 16.89) compared to controlled population (35.74 ± 16.78) and healthy controls (10.55 ± 2.20), p value < 0.001. A significant positive correlation was obtained between Serum ADA and HbA1c, Fasting Plasma Glucose and Post-prandial Glucose respectively. CONCLUSION There is a significant increase in Serum ADA activity in DM with increase in HbA1c levels which may play an important role in predicting the glycemic and immunological status in these patients.

Abstract
BACKGROUND The diagnosis of acute coronary syndrome remains challenging, as cardiac troponins and creatine kinase-MB do not detect myocardial ischemia. Ischemia modified albumin is biomarker positive within 6-10 minutes following ischemic onset, where oxygen free radicals leads to reduction in binding capacity of human serum albumin to transitional metal-cobalt. The objective of this study was to compare ischemia modified albumin between acute coronary syndrome patients and healthy controls, and evaluate diagnostic performance of ischemia modified albumin compared to cardiac troponins, creatine kinase-MB and electrocardiogram in acute coronary syndrome patients. METHODS Fifty ACS patients and 50 healthy controls were enrolled in this cross-sectional study. Ischemia modified albumin was measured after addition of known amount of cobalt to human serum albumin, followed by spectrophotometric determination of unbound cobalt fraction at 470 nm using dithiothreitol as coloring agent. Independent student t-test and One-way ANOVA to compare differences of mean between groups; diagnostic sensitivity and specificity of ischemia modified albumin was determined by receiver operating characteristic curve; McNemar-test was used to assess diagnostic performance of entire test parameters, when used alone and in combinations. RESULTS Ischemia modified albumin was significantly higher in acute coronary syndrome patients compared to controls (0.823±0.191 vs 0.410±0.081)(p<0.001). Receiver operating characteristic curve derived optimal cut-off of 0.475 Absorbance unit had sensitivity and specificity of 92% and 82% respectively (area under curve- 0.96). However, no significant differences in mean ischemia modified albumin values between three categories of acute coronary syndrome were seen. Sensitivity of ischemia modified albumin assay (92%) was significantly higher compared to electrocardiogram (72%), cardiac troponin I (18%), and creatine kinase-MB(42%). CONCLUSIONS Ischemia modified albumin is elevated in acute coronary syndrome patients with better diagnostic performance compared to electrocardiogram, cardiac troponin I, and creatine kinase-MB for early diagnosis, however, with limited ability to discriminate between ST-elevation myocardial infarction, non-ST-elevation myocardial infarction and unstable angina.

Abstract
BACKGROUND Iodine deficiency, thyroid dysfunction and development of thyroid autoimmunity during pregnancy may affect mother and the developing fetus. This study was carried out to find iodine status, thyroid dysfunction and thyroid autoimmunity among pregnant women. METHODS Ninety two pregnant women from three districts of eastern Nepal (Sunsari, Morang and Jhapa) were enrolled for the study, and urine and blood samples were collected. Urinary iodine concentration (UIC), free thyroxine (free T4), thyroid stimulating hormone (TSH), thyroglobulin and anti-thyroid peroxidase (TPO) antibody levels were estimated. RESULTS The median UIC, mean free T4 and TSH, median thyroglobulin and anti-TPO antibody in the pregnant women were 282.2 (158.42-376) μg/L, 1.14±0.41 ng/dL, 4.57±2.56 IU/mL, 6.5 (4.0-11.0) ng/mL, 1.52 (0.97-2.23) IU/mL respectively. In sufficient (<150 μg/L), adequate (150-249 μg/L) and above requirements (250-499 μg/L) iodine intake was observed in 17 (18.5%), 22 (23.9%) and 53 (57.6%) women respectively. Subclinical hypothyroidism and overt hypothyroidism were seen in 18 (19.5%) and 1(1.1%) women, respectively. Elevated thyroglobulin (>40 ng/mL) and positive anti-TPO antibody was observed in three (3.26%) women for both. CONCLUSIONS Iodine intake was sufficient among pregnant women recently, however, chronic iodine deficiency persisted in small fraction of pregnant women. Mild thyroid dysfunction was common, and thyroid autoimmunity was present in small portion of Nepalese pregnant women population.

Abstract
OBJECTIVES To assess iodine and iron nutritional status among Nepalese school children. METHODS A cross-sectional, community based study was conducted in the two districts, Ilam (hilly region) and Udayapur (plain region) of eastern Nepal. A total of 759 school children aged 6-13 y from different schools within the study areas were randomly enrolled. A total of 759 urine samples and 316 blood samples were collected. Blood hemoglobin level, serum iron, total iron binding capacity and urinary iodine concentration was measured. Percentage of transferrin saturation was calculated using serum iron and total iron binding capacity values. RESULTS The mean level of hemoglobin, serum iron, total iron binding capacity, transferrin saturation and median urinary iodine excretion were 12.29 ± 1.85 g/dl, 70.45 ± 34.46 μg/dl, 386.48 ± 62.48 μg/dl, 19.94 ± 12.07 % and 274.67 μg/L respectively. Anemia, iron deficiency and iodine deficiency (urinary iodine excretion <100 μg/L) were present in 34.5 %, 43.4 % and 12.6 % children respectively. Insufficient urinary iodine excretion (urinary iodine excretion <100 μg/L) was common in anemic and iron deficient children. CONCLUSIONS Iron deficiency and anemia are common in Nepalese children, whereas, iodine nutrition is more than adequate. Low urinary iodine excretion was common in iron deficiency and anemia.

Abstract
Spectrum of renal disease varies in different ethnic population, geographical location, and by environmental factors. The purpose of this study was to find out the clinical spectrum and occurrence of different pediatric renal diseases at a teaching hospital in the Eastern part of Nepal. All cases of renal diseases from one month to 15 years of age, attending the pediatric renal outpatient department and/or were admitted to the wards during the period of February 2012 to January 2013, were included in the study. Detailed clinical and laboratory evaluations were performed on all patients. Diseases were categorized as per standard definitions and managed with hospital protocols. Renal diseases accounted to be 206 cases (6.9%) of total annual pediatric admissions, of which (58%) were male and (42%) female. Acute glomerulonephritis (AGN) was the most common disorder (37.7%) followed by nephrotic syndrome (26.1%), urinary tract infection (21.3%), acute kidney injury (AKI) (17.9%), obstructive uropathy (1.9%), chronic kidney disease (CKD) (1.2%), and others. In AGN group, the most common cause was post-infectious glomerulonephritis (PIGN) (32.9%) followed by lupus nephritis (4%) and Henoch-Schonlein purpura nephritis (0.8%). Urine culture was positive in (9.22%) and the most common organism was Escherichia coli (57.9%). The causes of AKI were urosepsis, septicemia, and AGN (18.9%) each, followed by dehydration (13.5%). Mortality was found in 5% of cases and the etiologies were AKI in (72.7%), PIGN (18.1%), and CKD (9%). Renal diseases are a significant problem among children and are one of the common causes of hospital admission. These patients need comprehensive services for early identification and management.

Abstract
This longitudinal study was conducted in BP Koirala Institute of Health Sciences (BPKIHS), a Medical University situated in eastern Nepal, between May 2001 and December 2001. The main objective of the study was to identify the role of adenosine deaminase (ADA) activity in patients with visceral leishmaniasis (VL) for management. There was a significant increase in mean ADA activity in sera of 49 patients with VL (323.71±184.51 IU/L) compared with 50 samples of control groups (47.11±24.94 IU/L) from the same endemic area ( P<0.001). ADA activities were found to be significantly decreased (50.35±41.35 IU/L) in follow-up cases ( n = 19) after 30 days with sodium stibogluconate treatment at a dose of 20 mg/kg/day intramuscularly. The fall in the level of ADA (after treatment) in follow-up cases correlated with the cure of disease, as evident from improvement of vital signs and symptoms and the absence of Leishmania donavani bodies in the sera. The study therefore suggests the possibility of using human serum ADA as a convenient marker to evaluate the diagnosis of VL to support the clinical findings, especially in those settings where there is a lack of highly qualified personnel and diagnostic facilities.

Abstract
Metabolic syndrome (MetS) has been found to be associated with inflammatory molecules. This study was conducted among 125 MetS patients at B P Koirala Institute of Health Sciences, Dharan, Nepal to find an association of high-sensitivity C-reactive protein (hs-CRP) and serum uric acid with MetS components. Anthropometric measurements, blood pressure, medical history and blood samples were taken. Estimation of hs-CRP, serum uric acid, blood glucose, triglyceride and high density lipoprotein (HDL) cholesterol was done. hs-CRP had positive correlation with blood glucose (r = 0.2, p = 0.026) and negative with HDL cholesterol (r = −0.361, p < 0.001). Serum uric acid had positive correlation with waist circumference (r = 0.178, p = 0.047). Patients with elevated hs-CRP and uric acid had higher waist circumference (p = 0.03), diastolic BP (p = 0.002) and lower HDL cholesterol (p = 0.004) than others. Elevated hs-CRP and high uric acid were individually associated with higher odds for low HDL cholesterol (7.992; 1.785–35.774, p = 0.002) and hyperglycemia (2.471; 1.111–5.495, p = 0.029) respectively. Combined rise of hs-CRP and uric acid was associated with severity of MetS (p < 0.001) and higher odds for hyperglycemia (8.036; 2.178–29.647, p = 0.001) as compared to individual rise of hs-CRP or uric acid. The present study demonstrates that hs-CRP and serum uric acid are associated with MetS components, and the combined rise of hs-CRP and uric acid is associated with the increase in severity of MetS.

Abstract
Background A growing body of evidence suggests that metabolic syndrome is associated with endocrine disorders including thyroid dysfunction. Thyroid dysfunction in metabolic syndrome patients may further add to cardiovascular disease risk thereby increasing mortality. This study was done to assess thyroid function in metabolic syndrome patients and evaluate its relationship with the components of metabolic syndrome. Methods A cross sectional study was carried out among 169 metabolic syndrome patients at B P Koirala Institute of Health Sciences, Dharan, Nepal. Anthropometric measurements (height, weight, waist circumference) and blood pressure were taken. Fasting blood samples were analysed to measure glucose, triglyceride, high density lipoprotein (HDL) cholesterol and thyroid hormones (triiodothyronine, thyroxine and thyroid stimulating hormone). Results Thyroid dysfunction was seen in 31.9 % (n = 54) metabolic syndrome patients. Subclinical hypothyroidism (26.6 %) was the major thyroid dysfunction followed by overt hypothyroidism (3.5 %) and subclinical hyperthyroidism (1.7 %). Thyroid dysfunction was much common in females (39.7 %, n = 29) than males (26 %, n = 25) but not statistically significant (p = 0.068). The relative risk of having thyroid dysfunction in females was 1.525 (CI: 0.983–2.368) as compared to males. Significant differences (p = 0.001) were observed in waist circumference between patients with and without thyroid dysfunction and HDL cholesterol which had significant negative correlation with thyroid stimulating hormone. Conclusions Thyroid dysfunction, particularly subclinical hypothyroidism is common among metabolic syndrome patients, and is associated with some components of metabolic syndrome (waist circumference and HDL cholesterol).

Abstract
Background Deficiencies of iodine and iron may have adverse effect on thyroid function. This study was undertaken to investigate the association between iron status and thyroid function in Nepalese children living in hilly regions. Methods A cross-sectional study was conducted among 227 school children aged 6–12 years living in hilly regions of eastern Nepal. Urine and blood samples were analyzed for urinary iodine concentration, free thyroxine, free triiodothyronine, thyroid stimulating hormone, hemoglobin, serum iron and total iron binding capacity, and percentage transferrin saturation was calculated. Results The cohort comprised euthyroid (80.6 %, n = 183), overt hypothyroid (1.3 %, n = 3), subclinical hypothyroid (16.3 %, n = 37) and subclinical hyperthyroid (1.8 %, n = 4) children respectively. About 35.2 % (n = 80) children were anemic, 43.6 % (n = 99) were iron deficient and 19.8 % (n = 45) had urinary iodine excretion < 100 μg/L. Hypothyroidism (overt and subclinical) was common in anemic and iron deficient children. The relative risk of having hypothyroidism (overt and subclinical) in anemic and iron deficient children was 5.513 (95 % CI: 2.844−10.685, p < 0.001) and 1.939 (95 % CI: 1.091-3.449, p = 0.023) respectively as compared to non-anemic and iron sufficient children. Thyroid stimulating hormone had significant negative correlation with hemoglobin (r = −0.337, p < 0.001) and transferrin saturation (r = −0.204, p = 0.002). Conclusions Thyroid dysfunction, iron deficiency and anemia are common among Nepalese children. In this cohort, anemic and iron deficient children had poor thyroid function.

Abstract
BACKGROUND Faculty development by conducting regular training, workshops and research related to medical education has been a key feature to upgrade quality of medical education. OBJECTIVE The aim of this study was to explore responses of the health science teachers, students and peers after the workshop after providing training on student assessment tools and teaching-learning methods. METHOD Two teacher-training workshops were conducted to the faculty members of B.P. Koirala Institute of Health Sciences from the departments of basic, clinical and allied sciences in Oct. 2010 and Jan. 2011. Qualitative questionnaire based study was conducted, and the questions were validated before the study by expert peer review process. The effect of the training workshop in real classroom outcomes was assessed incorporating student's feedback, evaluation by peers and the self-evaluation by the teacher trainees. RESULT Pre-test and post-test scores of the participating teachers, before and after the workshop were 62.53 and 71.17 respectively. Among the participants 90.3% teachers expressed enhanced in their role as a teacher for medical undergraduates after the workshop. CONCLUSION In present study, the faculty members showed accrued interest to participate in teacher's training workshops. The peer evaluation of teacher's performance in their real classroom situations were rated higher than evaluation by the students. Therefore, such training workshops will have a greater impact on the ability of teachers in effective teaching in real classroom situations.

Abstract
BACKGROUND Chronic kidney disease (CKD) is becoming a serious health problem; the number of people with impaired renal function is rapidly rising. Progression of CKD is associated with having a number of complications, including thyroid dysfunction, dyslipidemia and cardiovascular diseases. This study was conducted to investigate thyroid function and lipid profile in CKD patients. METHODS A cross-sectional study was conducted among 360 chronic kidney disease patients at B P Koirala Institute of Health Sciences, Dharan, Nepal. Demographic features (age and sex) and medical history of diabetes mellitus, hypertension and cardiovascular diseases of each patient were noted, and blood samples (5 ml) were analyzed for serum urea, creatinine, glucose, free triiodothyronine (T3), free thyroxine (T4), thyroid stimulating hormone (TSH), total cholesterol, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol and triglyceride. RESULTS Thyroid dysfunction was found in 38.6 % CKD patients, the most common being subclinical hypothyroidism (27.2 %), followed by overt hypothyroidism (8.1 %) and subclinical hyperthyroidism (3.3 %). Hypercholesterolemia, low HDL cholesterol, undesirable LDL cholesterol and hypertriglyceridemia were observed in 34.4, 34.1, 35 and 36.6 % patients respectively. Stage 4 and 5 CKD patients had significantly higher risk of having thyroid dysfunction as compared to stage 3 patients. Significant risk factors for cardiovascular disease in CKD patients included presence of diabetes mellitus, hypercholesterolemia, undesirable LDL cholesterol and being in stage 4 and 5 (as compared to stage 3). CONCLUSIONS Thyroid dysfunction, hypercholesterolemia, low HDL cholesterol, undesirable LDL cholesterol and hypertriglyceridemia are common in CKD patients. Progression of CKD is accompanied by rise in hypothyroidism and cardiovascular disease.

Abstract
Background: Iodine deficiency is still a significant public health problem. In the rural plains of Nepal, it remains a mild-to-moderate public health problem among pregnant and lactating women despite the availability of iodized salt. To date, only limited attention has been paid to breast-milk iodine content despite its importance in the intellectual development of infants.Objectives: (i) To determine iodine content in mother’s urine, mother’s milk and to measure their respective child’s TSH level. (ii) To correlate iodine content of mother’s urine with child’s TSH level and also mother’s milk content with child’s TSH level.Setting and Design: cross sectional study in human using consecutive sampling techniqueMaterials and Methods: Mother’s urinary and milk iodine level was measured by Ammonium Persulfate Digestion Microplate method using Sandell-Kolthoff reaction in a sealing cassette (Hitachi, Japan) and child’s TSH by ELISA commercial Kit from Eliscan (RFCL, India) based on classical sandwich technique.Statistical analysis used: Spearman’s correlation was performed in quantitative variables. A p-value less than 0.05 and 0.001 were considered statistically significant and highly significant respectivelyResults: The median mother’s urine was 174.96 µg/L(97.39-215.43) and their respective median child TSH level was 3.86 mIU/L(2.66-4.80). Median mother’s milk iodine was 129.90 µg/L (94.14-165.94).There was significant negative correlation between mothers’ urinary iodine content and their child’s TSH (r2= -0.391, p = 0.005) and between mother’s urinary iodine and their child’s TSH (r2= -0.471, p = 0.001). There was positive correlation between mother’s milk iodine and mother urinary iodine but not statistically significant ((r2= 0.261, p = 0.067).Conclusion: Mothers urinary iodine, mother’s milk iodine and child TSH are interrelated with each other.Asian Journal of Medical Sciences Vol.7(1) 2015 40-48

Abstract
BACKGROUND Iodine deficiency is a major public health problem in many developing countries including Nepal. The present study was designed to investigate the urinary iodine excretion (UIE), thyroid function status and household salt iodine content (SIC) in school-aged children (SAC) and to establish the relationships between these factors. METHODS A community-based cross sectional study was conducted in selected schools of two districts, Tehrathum and Morang, lying in the hill and plain region of eastern Nepal respectively. A total of 640 SAC, (Tehrathum n = 274 and Morang n = 366) aged 6-11 years, were assessed for UIE and household SIC. Among the 640 children, 155 consented to blood samples (Tehrathum n = 78 and Morang n = 77) to test for serum thyroglobulin (Tg), thyroid stimulating hormone (TSH), free triiodothyronine (fT3) and free thyroxine (fT4). UIE was measured by ammonium persulfate digestion method. SIC was measured by iodometric titration method and Tg, TSH, fT4 and fT3 were measured by immunoassay based kit method. RESULTS In Tehrathum and Morang, 9.5 and 7.7% of SAC had UIE values of UIE <100 µg/L while 59.5 and 41% had iodine nutrition values of >299 µg/L, with median UIE of 345.65 and 270.36 µg/L respectively. The overall medians were as follows, Tg 14.29 µg/L, fT3 3.94 pmol/L, fT4 16.25 pmol/L and TSH 3.61 mIU/L. There was a negative correlation between UIE and Tg (r = -0.236, p = 0.003) and a positive correlation between UIE and SIC (r = 0.349, p < 0.0001). We found 19.5%, n = 15 and 16.7%, n = 13 subclinical hypothyroid cases in Morang and Tehrathum respectively. Iodometric titration showed only 6.4% (n = 41) of the samples had household SIC <15 ppm. Multivariate analysis revealed that use of packaged salt by SAC of Tehrathum district correlated with higher UIE values. CONCLUSIONS Our focused data suggests that collaborative universal salt iodization (USI) programs are improving the health of children in the Tehrathum and Morang districts of Nepal. We also found that excessive iodine in a large portion of the study groups is a substantial concern and iodine intervention programs need to deal with both deficient and excessive iodine scenarios that can both be present simultaneously in study populations.

Abstract
BACKGROUND Acute iodine excess in newborns can cause hypothyroidism, but there are limited data on the effects of iodine excess on thyroid function in older infants. The aim of this study was to measure the effects of chronic excess iodine intake on thyroid function in 6-24-month-old infants. METHODS In this cross-sectional study, infants (n=696) in eastern Nepal were studied. Spot urine samples, venous blood samples, and household salt samples were collected, and urinary iodine concentration (UIC), serum free thyroxine (fT4), thyrotropin (TSH), thyroglobulin (Tg), and titrated household salt iodine concentration (SIC) were measured. Daily iodine intake was calculated from UIC based on estimates of urine volume at this age. RESULTS Median (25th-75th percentile) household SIC was 89 (70-149) ppm, while national legislation stipulates a fortification level of 50 ppm. Median UIC was 407 (312-491) μg/L; 76% of infants had a UIC >300 μg/L, suggesting iodine excess. Calculated mean iodine intake in 12-24-month-old infants was 220 μg/day, exceeding the recommended safe upper limit for iodine at this age (200 μg/day). Among the infants, 15.8% had an elevated Tg, 7.4% had subclinical hypothyroidism, but <1% had overt hypothyroidism. UIC was not a significant predictor of thyroid function, thyroid hormones, or Tg. CONCLUSION In 6-24-month-old infants exposed to excessive iodine intake, ∼7% have subclinical hypothyroidism but <1% have overt hypothyroidism. These findings suggest the thyroid in late infancy is already able to adapt to high iodine intakes and, in most cases, maintain euthyroidism.

Abstract
Anemia is one of the most common public health problems in developing countries like Nepal. This study was done to find the prevalence of anemia among the children aged 4-13 years in eastern Nepal. A cross-sectional study was conducted in 2012 in four districts (Morang, Udayapur, Bhojpur and Ilam) of eastern Nepal to find the prevalence of anemia among the school children of eastern Nepal. Children aged 4-13 years were selected randomly from different schools of above districts and 618 venous blood samples were collected. Hemoglobin level was estimated by using cyanmethemoglobin method. The mean hemoglobin level was 12.2 ± 1.82 gm/dl. About 37.9% (n = 234) children were found anemic. Anemia prevalence was 42.4% (n = 78), 31.6% (n = 60), 45.3% (n = 48) and 34.8% (n = 48) among school children of Morang, Udayapur, Bhojpur and Ilam district, respectively. The study finds anemia as a significant health problem among the school children of eastern Nepal.

Abstract
BACKGROUND Oxidative stress and malnutrition are shown to have pathogenic effect in Chronic Obstructive Pulmonary Disease (COPD). AIM This study was done to assess the burden of oxidative stress in COPD and to determine its relation to their nutritional status. MATERIALS AND METHODS In this cross-sectional study, 100 COPD cases from emergency and medical ward and meeting inclusion criteria, along with age, sex and occupation (mainly farmers, housewives and drivers) matched 100 controls without COPD and meeting inclusion criteria were enrolled. Oxidative stress was assessed by measuring lipid peroxidation product, Malondialdehyde (MDA) and antioxidants, like Vitamin C, E and Red Blood Cell Catalase (RBCC). Mini Nutritional Assessment (MNA) tool and Body Mass Index (BMI) were used to assess nutritional status. STATISTICAL ANALYSIS Chi-square test was applied for categorical variable. Student t-test was applied for comparison of means. Analysis of Variance (ANOVA) was applied for comparison between groups followed by Bonferroni post hoc analysis. Pearson correlation method was used for quantitative variables. Statistical significance was defined as p< 0.05 (two tailed). RESULTS COPD cases had significantly high MDA level with low level of Vitamin E and catalase as compared to controls (p < 0.001). Most of the COPD cases were underweight (BMI ≤ 18.5 Kg/m(2)) and malnourished (MNA score less than 7). Bonferroni post-hoc analysis, showed significantly high burden of oxidative stress in underweight and malnourished cases as compared to normal weight (p < 0.05) among COPD cases. Highly significant correlation was seen between BMI and plasma MDA level (r = -0.27, p = 0.008) in COPD cases. CONCLUSION This study shows impaired oxidant/antioxidant balance along with malnutrition and underweight in COPD, which signals for considering antioxidant therapy along with nutritional management.

Abstract
Objectives. To assess thyroid function and associated risk factors in Nepalese diabetes mellitus patients. Methods. A cross-sectional study was carried out among 419 diabetes mellitus patients at B. P. Koirala Institute of Health Sciences, Dharan, Nepal. Information on demographic and anthropometric variables and risk factors for thyroid dysfunction was collected. Blood samples were analysed to measure thyroid hormones, blood sugar, and lipid profile. Results. Prevalence rate of thyroid dysfunction was 36.03%, with subclinical hypothyroidism (26.5%) as the most common thyroid dysfunction. Thyroid dysfunction was much common in females (42.85%) compared to males (30.04%) (p = 0.008) and in type 1 diabetes (50%) compared to type 2 diabetes mellitus (35.41%) (p = 0.218). Diabetic patients with thyroid dysfunction had higher total cholesterol, HDL cholesterol, and LDL cholesterol in comparison to patients without thyroid dysfunction. Significant risk factors for thyroid dysfunction, specifically hypothyroidism (overt and subclinical), were smoking (relative risk of 2.56 with 95% CI (1.99-3.29, p < 0.001)), family history of thyroid disease (relative risk of 2.57 with 95% CI (2.0-3.31, p < 0.001)), and female gender (relative risk of 1.44 with 95% CI (1.09-1.91, p = 0.01)). Conclusions. Thyroid dysfunction is common among Nepalese diabetic patients. Smoking, family history of thyroid disease, and female gender are significantly associated with thyroid dysfunction.

Abstract
BACKGROUND Universal salt iodization is considered the best strategy for controlling iodine deficiency disorders in Nepal. This study was done to find iodized salt use among Nepalese population and the iodine content of household salts. METHODS Six districts (Siraha, Saptari, Jhapa, Udayapur, Ilam and Panchthar) were chosen randomly from 16 districts of eastern Nepal for the study. In each district, three schools (private and government) were chosen randomly for sample collection. A total of 1803 salt samples were collected from schools of those districts. For sample collection a clean air tight plastic pouch was provided to each school child and was asked to bring approximately 15 gm of their kitchen salt. The information about type of salt used; 'two child logo' iodized salt or crystal salt was obtained from each child and salt iodine content was estimated using iodometric titration. RESULTS At the time of study, 85% (n=1533) of Nepalese households were found to use iodized salt whereas 15% (n=270) used crystal salt. The mean iodine content in iodized and crystal salt was 40.8±12.35 ppm and 18.43±11.49 ppm respectively. There was significant difference between iodized and crystal salts use and salt iodine content of iodized and crystal salt among different districts (p value <0.001 at confidence level of 95%). Of the total samples, only 169 samples (9.4% of samples) have iodine content<15 ppm. CONCLUSIONS Most Nepalese households have access to iodized salt most salt samples have sufficient iodine content.

Abstract
Diabetes mellitus is a common health problem of the world. Iron may be a part of the cause of the disease and its complications. Iron is a trace element which produces reactive oxygen species (ROS) participating through Fenton reaction and that ROS may be a cause to produce oxidative stress and further diabetic complications. The study aims to access the iron and its effect in producing oxidative stress in type 2 diabetic patients. Serum iron, total iron binding capacity (TIBC) and percentage transferrin saturation are calculated as the index of iron. Malondialdehyde (MDA) is estimated as index of oxidant and vitamin C, vitamin E are measured as index of antioxidants. This is a case control study conducted in the department of Biochemistry in collaboration with department of Medicine at B P Koirala Institute of Health Sciences (BPKIHS), Dharan, Nepal. 52 chronic type 2 diabetes mellitus patients and 52 age and sex matched normal healthy controls were included in the study. Plasma iron, TIBC, percentage transferrin saturation were found (89.14±30.50 μg/dL), (266.78±48.80 μg/dL), (36.61±14.31%) in diabetic cases as compared to (83.98±24.19 μg/dL), (279.08±40.23 μg/dL), (31.05±10.98%) of healthy controls. A significant increase in MDA level (6.35±1.52 nmol/ml in cases and 4.18±1.12 nmol/ml in controls, p<0.001) and significant decrease in vitamin C (0.85±0.19 mg/dL in cases and 1.28±0.21 mg/dL in controls, p<0.001) and vitamin E (0.85±0.25 mg/dL in cases and 1.34±0.38 mg/dL in controls, p<0.001) were observed.

Abstract
Objectives: The present study was conducted aiming to investigate lipid profile in patients with subclinical hypothyroidism as compared to age and sex matched controls.Methods: The study population consisted of total 80 subjects; 40 patients (cases) and 40 controls. Serum free tri-iodothyronine (fT3) and free thyroxine (fT4) were estimated by microplate competitive enzyme immunoassay, and thyroid stimulating hormone (TSH) measured by sandwich enzyme immunoassay. Lipid profile tests: Total Cholesterol, triglycerides, high density lipoprotein (HDL) cholesterol were estimated by enzymatic methods and low density lipoprotein cholesterol (LDL) was calculated by Friedewald’s formula.Results: Significant differences were observed between lipid parameters in case Vs controls: total cholesterol (4.9±1.1 Vs 4.3±1.0 mmol/L, P=0.03), triglycerides (1.9±0.7 Vs 1.6±0.6 mmol/L, P=0.02) and LDL cholesterol levels (3.5±1.1 Vs 2.9±0.9 mmol/L, P=0.02). In case Vs controls no significant differences were observed between HDL Cholesterol (1.1±0.2 Vs 1.1±0.7 mmol/L, P=0.07), VLDL (0.9±0.4 Vs 0.8±0.3 mmol/L, P=0.1) and Cholesterol/HDL ratio (4.48±1.40 Vs 4.06±0.89, P=0.118). Elevated TSH level were found in cases Vs controls (12.42±7.08 Vs 2.69±0.20 mIU/L, P=0.01) which was statistically significant. The subjects on control group were euthyroid, however increased fT3 (3.9±0.8Vs 4.6±0.8 pmol/L, P=<0.01) and fT4 (17.1±3.9Vs 21.2±.3.7 pmol/L, P=<0.01) values were observed in controls than cases, which was statistically significant.Conclusion: The results of the present study suggest that cases of subclinical hypothyroidism are at risk of dyslipidemia as compared to controls. Large population based studies are needed to generalize these findings and establish the therapeutic guidelines for implementing lipid lowering agents in subclinical hypothyroidism.Asian Journal of Medical Science, Volume-5(3) 2014: 22-25http://dx.doi.org/10.3126/ajms.v5i3.9251

Abstract
This study was designed to assess the urinary iodine concentrations of schoolchildren at baseline and after iodized salt supplementation in eastern region of Nepal. A cross sectional study was conducted from August 2009 to July 2011 among schoolchildren of three eastern districts of Nepal: Sunsari, Dhankuta, and Tehrathum. A sample of 828 school age children from the three districts was chosen for the study after obtaining written consent from their guardians. The schoolchildren treatment group (n=300) was provided with a supplement of iodized salt for six months. Urinary iodine concentration was estimated by ammonium persulfate digestion microplate method at baseline and after supplementation. Urinary iodine controls L1, L2 (Seronorm, Norway) were analyzed to obtain intra-assay CVs (L1 = 7.4%, L2 = 3.3%) and inter assay CVs (L1=23.5%, L2=11.26%). Median interquartile range urinary iodine concentration in the three districts: Sunsari, Dhankuta and Tehrathum at baseline versus intervention were 272.0 (131.5-473.0) microg/l versus 294.0 (265.0-304.0) microg/l (p=0.379), 247.0 (144.5-332.32) versus 361.0 (225.66-456.52) microg/l (p<0.001), and 349.5 (203.75-458.09) microg/l versus 268.76 (165.30-331.67) microg/l (p<0.001), respectively. This study indicated improved iodine status and increased median urinary iodine concentration after iodized salt supplementation. Regular monitoring of population urinary iodine concentration at national and regional levels should be performed to ensure that all individuals have optimal delivery of iodine nutrition.

Abstract
BACKGROUND Universal salt iodization remains the best strategy for controlling iodine deficiency disorders in Nepal. AIMS This study was designed to study the salt types and the household salt iodine content of school aged children in the hilly and the plain districts of eastern Nepal. MATERIAL AND METHODS This cross-sectional study was carried out on school children of seven randomly chosen schools from four districts, namely, Sunsari, Dhankuta, Sankhuwasabha and Tehrathum of eastern Nepal. The school children were requested to bring two teaspoonfuls (approx. 12-15 g) of the salt which was consumed in their households, in a tightly sealed plastic pouch. The salt types were categorized, and the salt iodine content was estimated by using rapid test kits and iodometric titrations. The association of the salt iodine content of the different districts were tested by using the Chi-square test. The sensitivity, specificity, positive predictive values, and negative predictive values of the rapid test kits were compared with the iodometric titrations. RESULTS Our study showed that mean±SD values of the salt iodine content in the four districts, namely, Sunsari, Dhankuta, Sankhuwasabha and Tehrathum were 34.2±17.9, 33.2±14.5, 27.4±15.1 and 48.4±15.6 parts per million (ppm). There were 270 (38.2%) households which consumed crystal salt and 437(61.8%) of the households consumed packet salts. CONCLUSIONS Our study recommends a regular monitoring of the salt iodization programs in these regions. More families should be made aware of the need to ensure that each individual consumes iodized salt.

Abstract
BACKGROUND Metabolic syndrome is a constellation of physical conditions and metabolic abnormalities, commonly occurring together, that increases an individual's risk for development of type 2 diabetes mellitus and cardiovascular diseases. Oxidative stress is associated with diabetes, hypertension and other cardiovascular diseases while the role of oxidative stress in pathogenesis of MS is not clearly defined. OBJECTIVES The study aims to find out the prevalence of metabolic syndrome in faculty and staff members at BP Koirala Institute of Health Sciences, Dharan, Nepal and to evaluate oxidative stress levels in subjects with metabolic syndrome. METHODS 118 healthy participants working at B. P. Koirala Institute of Health Sciences, Dharan, Nepal were selected at random for this cross-sectional study and blood samples were collected for the estimation of the following biochemical analytes; fasting glucose; triglycerides; total cholesterol; high density lipoprotein cholesterol; Albumin; uric acid; Bilirubin; Malondialdehyde; Catalase; Glutathione peroxidase; Superoxide Dismutase; Glutathione; vitamin C; and lastly vitamin E. Results In this cross-sectional study, 39% subjects were diagnosed with metabolic syndrome , particularly in sedentary subjects. There was no difference in oxidative stress except significant rises in serum uric acid levels and catalase activity in subjects diagnosed with metabolic syndrome . CONCLUSION The prevalence of metabolic syndrome is higher without oxidative stress in this study, which suggests that oxidative stress does not contribute to the pathogenesis of MS in otherwise healthy subjects.

Abstract
Tuberculosis (TB) is one of the most common infectious diseases in developing countries including Nepal. Delay in diagnosis and treatment of tuberculosis results in poor prognosis of the disease. This study was conducted to estimate diagnostic cut off values of Adenosine Deaminase (ADA) in cerebrospinal fluid (CSF) and pleural fluid and to evaluate the sensitivity, specificity, positive and negative predictive values ofADA in pleural fluid and CSF from patients with tuberculous and non-tuberculous disease. A total of 98 body fluid (CSF: 24, Pleural fluid: 74) specimens were received for the estimation of ADA. ADA activity was measured at 37 degrees C by spectrophotometric method of Guisti and Galanti, 1984 at 625nm wavelength. Among the patients enrolled for the study subjects for which CSF were received (n = 24) included 8 tuberculous meningitis (TBM), and 16 non-tubercular meningitis (NTM). Pleural fluid samples (n = 74) were received from 19 pulmonary TB with pleural effusion, 17 PTB without pleural effusion and 37 of non-tuberculous disease patients. CSF ADA activity were (11. 1 +/- 2.03 IU/L) and (5.3 +/- +1.89 IU/L) (p <00001) in TM and non-NTM groups and Pleural fluid ADA activity were (10 +/- 22.18 IU/L) and (23.79 +/- 11.62 IU/L) (p < 0.001) in PTB and non-TB groups respectively. ADA test in body fluids, which is simple, cost-effective and sensitive, specific for the tubercular disease is recommended to perform before forwarding the cumbersome and expensive procedures like culture and PCR for TB diagnosis.

Abstract
Background Perinatal asphyxia leading to hypoxic-ischemic encephalopathy (HIE) is a common problem causing multi organ dysfunction including myocardial involvement which can affect the outcome. Objective To evaluate the myocardial dysfunction in neonates having HIE by electrocardiographic(ECG) and cardiac enzymes (CK Total, CK-MB and Troponin I) and find out the relationship with HIE and outcome. Design/Methods This was a hospital based prospective study. Sixty term neonates who had suffered perinatal asphyxia and developed HIE were enrolled. Myocardial involvement was assessed by clinical, ECG, and CK Total, CK-MB and Troponin I measurements. Results Of 60 cases, 13(21.7%) were in mild, 27(45%) in moderate and 20(33.3%) belonged to severe,HIE. ECG was abnormal in 46 (76.7%); of these 19 (41.3%) had grade I, 13 (28.2%) grades II and III each and 1 (2.1%) with grade IV changes. Serum levels of CK Total, CK- MB and Troponin I were raised in 54 (90%), 52 (86.6%) and 48 (80%) neonates, respectively. ECG changes and enzymatic levels showed increasing abnormalities with severity of HIE, and the differences among different grades were significant (p = 0.002, 0.02, <0.001 and 0.004, respectively). Nineteen (32%) cases died during hospital stay. The non- survivors had high proportion of abnormal ECG (p = 0.024), raised levels of CK-MB (p = 0.018) and Troponin I (p = 0.008) in comparison to survivors. Conclusions Abnormal ECG and cardiac enzymes levels are found in HIE and can lead to poor outcome due to myocardial damage Early detection can help in better management and survival of these neonates.

Abstract
This is the first study characterizing spectrum of beta-thalassemia mutations in Nepalese population. Mutations were analyzed in 22 patients using 10 sets of allele-specific primers. Five of the mutations, namely F.S 41/42 (--TCTT), IVS1 nt5 (G-->C), IVS1 nt1 (G-->T), 619 bp deletion and F.S 8/9 (+G), were found to constitute 87.82% of total alleles studied. F.S 41/42 (--TCTT) was the commonest mutation. -88 (C-->T), Codon 16 (--C) and Codon 15 (G-->A), had a combined frequency of 12.18%. Distribution of mutations causing beta-thalassemia in different ethnic Nepalese groups was analyzed. The mutational profile in Nepal share several similarities with that from the two neighboring countries, India and China. Detection of more than one mutation in three cases of thalassemia trait raises the likelihood of existence of multiple mutations in cis in Nepalese thalassemic carriers. Such possibility has to be carefully considered while developing prenatal screening program for Nepalese population.

Abstract
BACKGROUND Medical education has experienced a rapidly changing scenario especially during the past three decades. Teachers training programs have emerged in recent years as a more in depth and comprehensive mechanisms for strengthening instructional skills and formulating assessment techniques among faculty members. OBJECTIVE The present study was carried out with the aim of assessing effectiveness of teacher training workshop on assessment techniques at B.P. Koirala Institute of Health sciences (BPKIHS), Dharan, Nepal. Methods: In this prospective questionnaire based study, the 26 entry level teachers were enrolled. They were requested to fill the questionnaire before and after the workshop on the assessment techniques at BPKIHS, Dharan. METHODS Twenty six teachers majority of whom were entry level teachers comprising of medical, dental, nursing and allied sciences participated in pre- and post test analysis on the various components of written and oral examinations. A two and half days long training was conducted having 9 hours of teaching interactive sessions, 6 hours of group exercises, daily evaluation and 3 hours of presentation by participants. There was high degree of agreement with most topics of the assessment training. RESULTS There was a significant gain in knowledge (p < 0.001) by the participants. All the participants (100%) agreed upon the training being informative and learned new things about assessment. More practice session with longer duration with invited resource persons were also suggested for an effective session. CONCLUSION Thereis an immense opportunity for a better and comprehensive training in evaluation techniques in medical education..

Abstract
BACKGROUND Subclinical hypothyroidism itself is associated with serious complications and also there is a known risk of subclinical hypothyroidism patients getting converted into overt disease. OBJECTIVES The objective of the present study was to fi nd out the prevalence of subclinical hypothyroidism in the suspected cases i.e. amongst the cases attending the thyroid laboratory at B.P. Koirala Institute of Health Sciences, Dharan, Nepal. MATERIALS AND METHODS It was a retrospective cross sectional study. Data of the free T3, free T4 and TSH estimations of the year 2007 of the Thyroid lab at BPKIHS, Dharan, Nepal was analyzed. ELISA based free T3, free T4 and TSH tests in the serum had been performed in all the cases. RESULTS Total cases were 1714 including 24.446% males and 75.554% females. Cases with raised TSH levels were 26.021%, cases with normal TSH levels were 54.66% and cases with low TSH levels were 19.316%. Total 350 cases (20.42 %) had subclinical hypothyroid dysfunction which includes 84 (4.901 %) males and 266 (15.519%) females. And the maximum percentage of cases in either gender was between the age groups 20 -59 years. CONCLUSION The prevalence of subclinical thyroid hypothyroidism amongst the suspected cases was 20.42 % which is much higher compared to the other parts of the world. The highest percentage was found in the female age group 20 - 59 years. The routine screening of the whole population is not cost effective and on the basis of the present study it is suggested that there may be routine screening of the selected populations, especially women between 20 to 59 years of age in Nepal region. The preferred screening method advised is a sensitive ELISA based TSH test.

Abstract
Background. This study was carried out to establish the prevalence of cardiovascular risks such as hypertension, obesity, and diabetes in Eastern Nepal. This study also establishes the prevalence of metabolic syndrome (MS) and its relationships to these cardiovascular risk factors and lifestyle. Methods. 14,425 subjects aged 20–100 (mean 41.4 ± 15.1) were screened with a physical examination and blood tests. Both the International Diabetic Federation (IDF) and National Cholesterol Education Programme's (NCEP) definitions for MS were used and compared. Results. 34% of the participants had hypertension, and 6.3% were diabetic. 28% were overweight, and 32% were obese. 22.5% of the participants had metabolic syndrome based on IDF criteria and 20.7% according to the NCEP definition. Prevalence was higher in the less educated, people working at home, and females. There was no significant correlation between the participants' lifestyle factors and the prevalence of MS. Conclusion. The high incidence of dyslipidemia and abdominal obesity could be the major contributors to MS in Nepal. Education also appears to be related to the prevalence of MS. This study confirms the need to initiate appropriate treatment options for a condition which is highly prevalent in Eastern Nepal.

Abstract
BACKGROUND Problem based learning (PBL) has made major impact on curricular designing and practice in medical education for the last forty years. Incorporation of PBL approach in medical education has been a challenge and opportunity for both educationists on how to impart change and medical teachers on how to internalise the change. OBJECTIVES This paper aimed to investigate experiences, achievement and responses of medical teachers at B. P. Koirala Institute of Health Sciences (BPKIHS), Nepal. MATERIALS AND METHODS There were 25 heterogeneous groups of teachers, majority of them were entry level. Pre- and Post-test question were taken from various topics relevant to PBL such as learning strategy and principles of adult learning, PBL practice at BPKIHS, tutorial session and role of a tutor, making resource session interactive, designing PBL problems, planning educational objectives in PBL, formulation of problem for PBL. In addition to it participants' perception on development and dissemination of PBL manual and effectiveness of workshop were also included in the questionnaire. RESULTS There was significant gain in knowledge following the workshop (p<0.001). The perception of the teacher found quite relevant and useful for adopting new role as tutor. The respondent teachers noted that skills they learned during the training will be applicable to their job situation. They stressed for an additional training for reinforcement and update with new trends and tools in PBL. CONCLUSION Therefore, such trainings for faculty development would be highly beneficial to inculcate new competencies in PBL.

Abstract
Abstract. The present study was undertaken to evaluate differences between urban and rural Nepali populations in terms of hyperglycemia, socioeconomic position (SEP) and hypertension, through a community based survey in Sunsari District, eastern Nepal. Blood glucose levels were measured in participants (N = 2,006) S30 years old from urban and rural communities and were classified according to WHO criteria (1998) into normoglycemia (NGY), impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and hyperglycemia (HGY). SEP was assessed by structured health interview along with anthropometric measurements and behavioral variables. Hypertension was classified per Joint National Committee (JNC-VII) criteria. Ten point three percent and 11.9% of subjects in this survey (13.3% urban and 11.0% rural) gave a family history and personal history of diabetes mellitus, respectively. Of urban participants (n = 736) with no history of diabetes 70 (9.5%) had HGY and 143 (19.4%) had glucose intolerance (IFG and IGT). Of rural participants (n = 1,270) 114 (9.0%) had HGY and 176 (13.9%) had glucose intolerance. There was an increasing trend in numbers of cases of hyperglycemia and intolerance with increasing age (chi2 198.2, p < 0.001), body mass index (BMI) (chi2 35.1, p < 0.001), SEP (chi2 48.5, p < 0.001) and hypertension (chi2 130.6, p < 0.001). Rural participants had a lower odds ratio [0.706; 95% confidence interval (CI) 0.455-1.096] of having hyperglycemia than urban participants. Individuals with medium and higher SEP had a lower odds ratio (0.878; CI 0.543-1.868) and higher odds ratio (1.405; CI 0.798-2.474), respectively, compared to individuals with lower SEP of having HGY. Both urban and rural populations are at risk for hyperglycemia and glucose intolerance. Individuals having a medium SEP had lower risk of diabetes mellitus than individuals from lower and higher SEP.
