Evaluation of SARS-CoV-2 Humoral Response Following Vaccination with ChAdOx1 nCoV-19 (Covishield™) and/or Sinopharm, BBIBP-CorV (Vero cell™).

BACKGROUND: Billions of doses of COVID-19 vaccine have been introducing in the world to prevent pandemic COVID-19. Higher efficacy but limited data are available for its longevity. We aimed to find out the IgG Anti-SARS Cov-2 antibody level among frontline healthcare workers after two doses of vaccines. METHODS: A cross-sectional study was carried among 170 HCPs of Seti Provincial Hospital of western Nepal, who were more than 18 years, and had taken two doses of either one of COVID 19 vaccine. All those participants, who were on leave during the data collection tenure (1st February 2022 to 28th February 2022) and/or did not consent to participate were excluded. Mindray SARS-CoV-2 S-RBD IgG assay kit based on CLIA method, was used whose target antigen is S-RBD (spike protein of receptor binding domain) antigen. The IgG immunoglobulin is detected and cut off value ≥10 AU/ml is considered positive. RESULTS: Based on the recommended cut off, the antibody was present in more than 90% across both groups of vaccinee i.e. the positive antibody titer at a mean duration of 7.31 months was 93.53% overall (93.75% and 93.44% in Vero cell™ and Covishield™ vaccinees respectively). There were 3.92 times high odds of high antibody titer (≥250 AU/ml) in Covishield™ group (OR: 3.92, 95% CI: 1.86-8.26, P-value: <0.001) than in Vero cell™ group of vaccinee. Similarly, there were significant difference of high titer of antibody across groups with more than six months of elapse of vaccination (OR: 2.18, 95% CI: 1.06-4.49, P-value: <0.001) than with less than six months of elapse of vaccination. CONCLUSIONS: The humoral response was higher among HCPs who received two-doses vaccination with ChAdOx1 nCoV-19 (Covishield™) and/or Sinopharm, BBIBP-CorV (Vero cell™) vaccine, and among those with six or more months of elapse of vaccination. The seroprevalence of SARS-CoV-2 following two-doses vaccination among HCPs was more than nine-tenths.

Serum iron Profile of Patients with Sickle Cell Disease and its Association with Socio-demographic Characteristics and Duration of Diagnosis.

BACKGROUND: Sickle cell anemia is the most common hemoglobinopathy in the world. The study aimed to evaluate the iron profile and its association with socio-demographic characteristics in patients with sickle cell disease. METHODS: A hospital-based descriptive cross-sectional study was conducted to know the iron profile and its socio-demographic association in patients with sickle cell disease. RESULTS: The average serum iron, TIBC, and transferrin saturation were 16.75 ± 6.40 mcgMole/L, 69.46 ± 16.94 mcg/dl and 25.15 ± 12.51% respectively. The serum ferritin ranged from 10.00 to 3000.00 ng/ml. The proportion of participants with normal serum iron, TIBC, serum ferritin, and transferrin saturation were 86.10%, 0.00%, 33.90% and 36.40% respectively. All of the participants of this study had low TIBC (1005), and more than half of the participants had elevated serum ferritin (56.40%). CONCLUSIONS: Iron overload is a common complication of sickle cell disease. There was no association of age and sex with iron profile. The TIBC variation between the Chaudhary ethnic group compared to other ethnic groups signifies the ethnic role in the iron profile.

Association of urinary albumin-to-creatinine ratio with lipid abnormalities and glycemic control in patients with type 2 diabetes mellitus.

Introduction: While proteinuria aggravates dyslipidemia in diabetic patients, dyslipidemia further worsens proteinuria via inflammatory cytokines-mediated glomerular damage. Urinary albumin creatinine ratio (ACR) is an easy and reliable method of detecting proteinuria. This study aims to determine the association of ACR with lipid abnormalities and glycemic control in the Nepalese population. Methods: This was a cross-sectional study conducted among 201 diabetes patients visiting the outpatient department of internal medicine. Based on ACR values, patients were categorized as nonalbuminuric (less than 300 µg/mg) or albuminuric (more than 300 µg/mg). An unpaired t-test was used to compare the mean of various lipoproteins in these two categories. Binary logistic regression was used to check the association of ACR with sociodemographic factors (age, sex, and education), hypertension, and glycated hemoglobin. Results: Albuminuric patients had higher mean cholesterol (192.8±53.5 vs. 184.2± 37.6; P=0.209), triglyceride (194.9±97.8 vs. 164.4±73.7; P=0.017) and low-density lipoprotein (99.9±38.4 vs. 90.0±27.4; P=0.034) but lower high-density lipoprotein (53.9±18.5 vs. 61.3±19.9; P=0.008) compared to nonalbuminuric patients. There was a significant difference in mean HbA1c values across albuminuria and nonalbuminuria groups (7.1±1.1 vs. 6.7±0.8; OR: 1.4, 95% CI=1.1-1.9, P=0.030). Conclusions: Urine ACR of more than 30 mg/gram was associated with higher triglyceride and low-density lipoprotein levels and lower high-density lipoprotein levels. The HbA1c level strongly correlates with the development of albuminuria.

Assessment of rational use of antimicrobials: a cross-sectional study among people of Nepal.

Inappropriate antimicrobial use leading to antimicrobial resistance is a matter of public health concern globally. This research was conducted with the objective of preventing antimicrobial misuse across knowledge, behavior, and practice domains among the general people of Nepal. Methods: It was a cross-sectional survey conducted among 385 participants visiting tertiary care center from all over Nepal from February 2022 to May 2022. Modified Bloom's cut-off point was utilized to categorize the participants' overall knowledge, behavior, and practice. The chi-square (χ 2) test and odds ratio (OR) using binary logistic regression at 95% CI and Spearman's rank correlation coefficient test (r) were calculated wherever appropriate. Results: More than three-fifths of the participants (248, 64.42%) demonstrated good behavior, whereas less than half of the participants showed good knowledge (137, 35.58%) and practice (161, 41.82%) about rational use of antimicrobials. Health professionals had higher knowledge (OR: 1.07, 95% CI: 0.70-1.62) and good behavior (OR: 0.42, 95% CI: 0.27-0.64) than other professionals (P<0.05). Those with higher income [≥50 000 NRS (Nepalese rupees)] had good behavior (OR: 3.37, 95% CI: 1.65-6.87) and good practice (OR: 2.58, 95% CI: 1.47-4.50) scores than those with less monthly income (P<0.05). Similarly, higher educational degrees, viz. master's and/or above, had good behavior (OR: 4.13, 95% CI: 2.62-6.49) and good practice scores (OR: 2.55, 95% CI: 1.68-3.87). Additionally, there were significant positive correlations between knowledge (K), behavior (B), and practice (P) scores (r=0.331 for K and B, r=0.259 for K and P, and r=0.618 for B and P, respectively; P<0.05). Conclusions: The findings imply the demand for effective legislature, strict enforcement of the drug act, and proper implementation of plans and policies to curb antimicrobials misuse. Lack of execution of existing laws and the unawareness of the public led to the extravagant use of antimicrobials.

Assessment of Understanding and Practices of Community Pharmacy Personnel to Tackle COVID-19 Pandemic.

BACKGROUND: The skill, accessibility, and knowledge of community pharmacists have been paramount in managing pandemics. This study was conducted to assess the knowledge, attitude, and practice of community pharmacy personnel towards tackling COVID-19 pandemic which might help concerned authorities to take effective actions to eliminate the gaps for the management of such pandemic in an efficient way. METHODS: A cross-sectional study was conducted among 428 community pharmacy personnel from different community pharmacies in Kathmandu, Nepal from December 2021 to February 2022. Statistical analysis was done through SPSS® v21 and MedCalc for Windows v12.3.0. RESULTS: Most of the participants (42.76%) had certificate-level degrees in their respective fields and one to five years of working experience (48.84%). Only 29.67% of the respondents had good knowledge towards tackling COVID-19, whereas good attitude and practice were demonstrated by 59.11% and 42.29% respectively. The participants with higher degrees and more working experience had better knowledge, attitude, and practice. Education level bachelor and above was independent predictor of good knowledge (OR 20.69, 95% CI 11.30-37.90). Knowledge and practice (Spearman's rho: 0.135; P ≤0.005) and attitude and practice (Spearman's rho: 0.095; P = 0.049) scores were positively correlated. CONCLUSIONS: The significant association of community pharmacy personnel's educational level with knowledge, attitude, and practices demands the necessity of policy-making bodies' involvement for the mandatory presence of well-qualified pharmacists and regular training at the community pharmacy level. Furthermore, it is high time to reinforce the drug regulatory acts, regulations, and codes all over the nation.

Prevalence and risk factors of chronic kidney disease among patients with type 2 diabetes mellitus at a tertiary care hospital in Nepal: a cross-sectional study.

OBJECTIVE: To estimate the prevalence of chronic kidney disease (CKD) among patients with type 2 diabetes mellitus (T2DM) and determine the sociodemographic and clinical risk factors associated with CKD. DESIGN AND SETTINGS: Cross-sectional study among diabetic outpatients of a tertiary hospital in Nepal. PARTICIPANTS: 201 patients with T2DM above 18 years of age. INTERVENTION: Participants completed a questionnaire regarding their socioeconomic information and underwent pertinent physical and haematological examinations. PRIMARY AND SECONDARY OUTCOMES MEASURE: The prevalence and risk factors of CKD among patients with T2DM. RESULTS: The prevalence of CKD in T2DM was 86.6%. In univariable analysis, the variables like age (p=0.026), hypertension status (p=0.002), duration of diabetes (p=0.009) and haemoglobin levels (p=0.027) were significantly associated with CKD among the participants with T2DM. Kruskal-Wallis H test showed that age was significantly different between various CKD stages. Multivariate analysis demonstrated a significant relationship between CKD with age (Adjusted odds ratio (AOR) 3, 95% CI 1.1 to 8.8) and literacy status (AOR 5.8, 95% CI 1.4 to 24.6) CONCLUSION: Advancing age, concomitant hypertension, increasing duration of T2DM and presence of anaemia were found to be important risk factors of CKD. Age is the most important predictor of CKD showing increasing prevalence in the elderly population. Periodic screening tests are essential at an early age to identify kidney diseases at incipient stages, thereby preventing progression to end-stage renal disease.

Association of Anthropometric Indices with Menstrual Abnormality among Nursing Students of Nepal: A Cross-Sectional Study.

Introduction: Obesity has been reported to be linked with menstrual abnormalities including abnormality in cycle length, duration, and period blood loss. However, which anthropometric parameter is a better marker of menstrual abnormality is yet unknown. This study aims to explore the association of BMI, waist-hip ratio (WHR), and waist-height ratio (WHtR) with menstrual abnormalities. Methods: This was a cross-sectional study conducted among 240 nursing students on two nursing campuses of Nepal. Demographic and menstrual characteristics related data were collected from the participants via the face-to-face interview technique followed by anthropometric measurements. Binary logistic regression was used to study the association of BMI, WHR, and WHtR with menstrual characteristics. Univariable and multivariable regression models were calculated at 95% confidence interval and a P value of 0.05 using a Statistical Package for Social Sciences, IBM SPSS® v21 (IBM, Armonk, New York). Results: Out of 240 participants, 52 participants (21.67%) were underweight (<18.5 kg/m2), and 47 participants (19.58%) were either overweight (≥23 kg/m2) or obese (≥25 kg/m2). Overweight and obese BMI was associated with abnormality in menstrual cycle length (AOR = 4.24; 95% CI = 1.77-10.17), duration of the menstrual period (AOR = 2.52; 95% CI = 1.09-5.81), and periodic menstrual blood loss (AOR = 9.04; 95% CI = 3.55-23.01). Increase in WHtR (>0.5) was associated with abnormal cycle length (AOR = 3.09; 95% CI = 1.09-8.80) and abnormal period duration (AOR = 3.05; 95% CI = 1.10-8.44). An increase in WHR (>0.8) was associated with abnormal cyclical menstrual blood loss (AOR = 4.93; 95% CI = 1.55-15.71). Conclusions: Obesity predisposes to menstrual irregularities. BMI is a better predictor of menstrual irregularity as the increase in BMI is associated with abnormality in menstrual cycle length, period duration, and blood loss. Increased WHR was associated with periodic blood loss only. Increased WHtR was associated with abnormal cycle length and period duration, but not menstrual blood loss.

An Epidemiological Study of Injuries in Karnali, Nepal.

BACKGROUND: Trauma, a major public health concern in remote highlands of Nepal, has led to considerable morbidity and mortality. The study elucidates the pattern and characteristics of trauma at the only tertiary care hospital in the Karnali province, Nepal. MATERIALS AND METHODS: Case records of all injured patients who presented to the emergency department from January to December 2018 were analyzed for demographic data, types of injuries, body parts injured, the outcome of the treatment, and distribution of injuries with respect to age and sex. RESULTS: A total of 460 injured patients (age: 26.5 ± 19.67 years, range: 0.5-84) were studied consisting of 282 (61.3%) males and 178 (38.7%) females, with a male-to-female ratio being 1.58:1 (P = 0.001). Unintentional injuries were the predominant form of trauma (n = 383, 84.1%), with fall (n = 194, 42.2%), road traffic crashes (RTC) (n = 161, 35%), and physical assaults (n = 73, 15.9%) being the top three leading causes in order. Fall injury and RTC were most prevalent in children, accounting 12.8% (59) and 9.3% (43) of the total injuries, respectively. The physical assaults were predominant (n = 23, 5%) in adults (20-29 years). Male patients significantly outnumbered females for all types of injuries. Soft tissue followed by head and extremities was the most common site of injuries. CONCLUSION: Trauma in Karnali is a predominantly early age male occurrence, with fall injury being the leading etiological factor, followed by injuries due to RTC and physical assaults. Soft tissue, head, and extremities were the major sites of injuries. Reducing fall injuries, RTC, and physical assaults will likely reduce mortality and morbidity due to trauma in this province.

Hemoglobin levels and anemia evaluation among pregnant women in the remote and rural high lands of mid-western Nepal: a hospital based study.

BACKGROUND: Anemia though is a major risk factor for unfavorable pregnancy outcomes; no previous studies have yet described the hemoglobin (Hb) concentrations and anemia prevalence among pregnant women of remote mid western highlands of Nepal where the aggravating factors that increase the risk of anemia are very common. In addition, the physiological adaptive Hb rise to altitude was considered in the study while evaluating anemia. Thus, our primary objectives were to study the hemoglobin levels and prevalence of anemia among pregnant women of Jumla and its adjoining districts, and to assess the potential associations of hemoglobin and anemia with women's characteristics. METHODS: The study was conducted in 319 singleton term non-smoker pregnant women who visited to the teaching hospital for delivery. Their blood samples were tested for Hb and related sociodemographic information was collected. One-way analysis of variance (ANOVA) and independent t-test were used to compare the mean Hb levels. Multiple linear regression model and multiple logistic regression model were used to assess the association of Hb level and anemia with pregnant women's characteristics. The prevalence of anemia was calculated based on the altitude and pregnancy-adjusted Hb cut off value for anemia [{11+ adjustment factor (1.3)} gm./dl]. RESULTS: The overall mean hemoglobin concentration was (13.497 ± 1.64) gm/dl, ranging from 8 to 19.20 g/dl. The pregnant women Hb level showed significant association with their age (Coeff = 0.059; 95% CI: 0.011, 0.106; p = 0.015) and parity (Coeff = - 0.21; 95% CI: - 0.382, - 0.038; p = 0.017). The overall prevalence of anemia in the study population was 17.9% (57/319), which varied with age, parity and ethnicity. The disadvantaged Janajatis were more likely (OR = 4.615, 95% CI: 1.48, 14.35, p = 0.008) to have anemia compared to upper cast group. CONCLUSION: The mean Hb concentration was high and prevalence rate of anemia was low among pregnant women in karnali zone compared to average Nepali pregnant women. Women's age and parity were significant predictors of Hb level. Ethnicity, however, was associated with the occurrence of anemia.
