Molecular characterization of influenza virus circulating in Nepal in the year 2019.

Influenza (sometimes referred to as "flu") is a contagious viral infection of the airways in the lungs that affects a significant portion of the world's population. Clinical symptoms of influenza virus infections can range widely, from severe pneumonia to moderate or even asymptomatic sickness. If left untreated, influenza can have more severe effects on the heart, brain, and lungs than on the respiratory tract and can necessitate hospitalization. This study was aimed to investigate and characterize all types of influenza cases prevailing in Nepal and to analyze seasonal occurrence of Influenza in Nepal in the year 2019. A cross sectional, retrospective and descriptive study was carried out at National Influenza Center (NIC), National Public Health Laboratory Kathmandu Nepal for the period of one year (Jan-Dec 2019). A total of 3606 throat swab samples from various age groups and sexes were processed at the NIC. The specimens were primarily stored at 4 °C and processed using ABI 7500 RT PCR system for the identification of Influenza virus types and subtypes. Data accessed for research purpose were retrieved from National Influenza Centre (NIC) on 1st Jan 2020. Of the total 3606 patients suspected of having influenza infection, influenza viruses were isolated from 1213 (33.6%) patients with male predominance. The highest number of infection was caused by Influenza A/Pdm09 strain 739 (60.9%) followed by Influenza B 304 (25.1%) and Influenza A/H3 169 (13.9%) and most remarkable finding of this study was the detection of H5N1 in human which is the first ever case of such infection in human from Nepal. Similar to other tropical nations, influenza viruses were detected year-round in various geographical locations of Nepal. The influenza virus type and subtypes that were in circulation in Nepal were comparable to vaccine candidate viruses, which the currently available influenza vaccine may prevent.

Comparative study on molecular and higher-order structures of legume seed protein isolates: Lentil, mungbean and yellow pea.

Lentils and mungbean proteins are under-researched compared to pea and soybean. Lentils (green, red and black-lentils), mungbean and yellow pea protein isolates were obtained by alkaline extraction (pH 9)-isoelectric precipitation (pH 4.5) and investigated for molecular and higher-order structures using complementary and novel approaches. These extracted isolates showed comparable protein content but significantly greater nitrogen solubility index (NSI > 85 %) than commercial pea and soy protein isolates (NSI < 60 %). Based on molecular weight estimations from sodium dodecyl sulphate-polyacrylamide gel electrophoresis analysis, the soluble proteins of lentils and yellow pea were identified as legumin-like and vicilin-like, while mungbean was dominated by vicilin-like proteins. The soluble extracts were confirmed to be in native structural condition by size exclusion chromatography and nano-differential scanning calorimetry, unlike commercial extracts. Further differences in secondary structure were evident on circular dichroism spectra of the soluble extracts and deconvolution of the Amide I region (1700-1600 cm-1) from Fourier Transform Infrared of the total protein.

Navigating a Pandemic: A Qualitative Study of Knowledge, Sources of Information, and COVID-19-Related Precautions Taken by HBCU Students.

The coronavirus (COVID-19) has spread quickly across the nation with a disproportionate impact on Black Americans. Many college-aged students receive their COVID-19-related information through social media and television even though research suggests that social media sources are more likely to be incorrect. Some students report trusting these sources over government sources such as the CDC and WHO. The purpose of this study was to understand Historically Black College and University (HBCU) students' COVID-19 knowledge, sources of information, and planned precautions. There were 21 in-depth interviews conducted with students attending a large southern HBCU during Spring 2020. Themes regarding knowledge included the following: it is a flu-like condition, it has international roots, there is inaccurate and changing information, and it is a pandemic. Themes regarding sources included: the news, US government and related officials, social media, interactions with family, and other social interactions. Themes regarding severity included the following: statistics, a distrust for hospital reporting, a belief that COVID-19 deaths were conflated with baseline health, peer influence, and familial influence. Themes regarding precautions included the following: proper mask use, hand washing/ sanitizing, avoiding large crowds/small crowds only, physical distancing, COVID-19 testing/symptom monitoring, and COVID-19 vaccination.

Effectiveness of a group-based Diabetes Prevention Education Program (DiPEP) in a population with pre-diabetes: a cluster randomised controlled trial in Nepal.

Background: Although several lifestyle intervention studies have been conducted in low/middle-income countries, there were no such studies in Nepal. Therefore, a group-based culturally tailored Diabetes Prevention Education Program (DiPEP) was conducted recently. The study aimed to evaluate the effect of DiPEP in glycated haemoglobin (HbA1c), weight, waist circumference, physical activity and diet among population with pre-diabetes. Method: A two-arm cluster randomised controlled trial was conducted in 12 clusters of two urban areas in Nepal. The DiPEP was a 6 month intervention (four 1-hour weekly educational sessions and 5 months of follow-up by community health workers/volunteers (CHW/Vs)). A postintervention assessment was done after 6 months. Linear mixed model was used to estimate the mean difference in primary outcome (HbA1c) and secondary outcomes (weight, waist circumference, physical activity and diet) between intervention and control arms, adjusted for baseline measure. Results: In intention-to-treat analysis with a total of 291 participants, the estimated mean difference in HbA1c was found to be 0.015 percentage point (95% CI -0.074 to 0.104) between the intervention arm and the control arm, while it was -0.077 (95% CI -0.152 to -0.002) among those who attended at least 3 out of 4 educational sessions. The estimated mean difference in weight (in participants who attended ≥1 educational session) was -1.6 kg (95% CI -3.1 to -0.1). A significantly lower grain consumption was found in intervention arm (-39 g/day, 95% CI -65 to -14) compared with the control arm at postintervention assessment. Conclusion: Although compliance was affected by COVID-19, individuals who participated in ≥3 educational sessions had significant reduction in HbA1c and those who attended ≥1 educational session had significant weight reduction. Grain intake was significantly reduced among the intervention arm than the control arm. Hence, group-based lifestyle intervention programmes involving CHW/vs is recommended for diabetes prevention. Trial registration number: NCT04074148.

Contextualizing the racial gradient in covid-19 outcomes: Narratives from HBCU students.

COVID-19 spread across the nation with Black Americans experiencing twice of the prevalence of deaths than White Americans. Black American college students are facing a unique set of biopsychosocial costs including less retention and poorer mental health. Therefore, the purpose of this study was to examine how Historically Black College or University (HBCU) students contextualize COVID-19. Interviews were conducted with 19 participants and lasted 40-60 minutes. They discussed topics including: their COVID-19 knowledge, precautionary measures, and barriers and promoters of school success were covered. Data were coded through semi-open coding and discussed among the research team. Responses were summarized by eight themes: emotional responses, colorblind rhetoric, lack of healthcare, essential work, distrust for the medical field, barriers to precautions like supply shortages and environmental factors, and poor baseline health. These findings may be used to develop interventions that moderate the impact of COVID-19 and future pandemics on mental health.

"Lockdown Dermatoses" during COVID-19-A Series of 127 Patients from the Indian Subcontinent.

Lockdown was enforced in many countries across the globe to flatten the coronavirus disease (COVID-19) curve. In these difficult times, people with skin diseases faced unique challenge, as major clinical facilities came to a standstill. Teledermatology helped to an extent to bridge this provider-seeker gap to an extent. We compiled data of patients seeking dermatology services during this period in Bangladesh, India, and Nepal. Most of the patients were middle-aged (70%) and had good access to teledermatology. Dermatoses were primarily due to frequent handwashing, use of alcohol-based sanitizers, excessive use of water (12.6%), improper skin care (43.3%), sun exposure (20.5%), lockdown-induced stress (22.04%), infections (15.75%), flare of preexisting diseases (8.66%), and hair disorders (11%). Many dermatoses had a causal overlap. Teledermatology proved to be useful for patients with skin diseases who were unable to access direct face-to-face consultations.

Lipectomy for Symptomatic Relief of Lymphangioma Circumscriptum.

We present two cases of lymphangioma circumscriptum (LC) that demonstrated characteristics of half-and-half lacunae or hypopyon sign in dermoscopy. The first case was that of a 19-year-old female patient with localized lymphangioma since childhood, presenting with continuous oozing of blood and fluid from the lesion. The second patient presented with extensive disease with verrucous growths and clear vesicles over the right chest wall. Both patients reported an impact on their quality of life due to constant oozing of the lesions. The magnetic resonance imaging showed depth and extent in localized versus extensive forms of the same condition. A lipectomy was performed on both patients to destroy subcutaneous connecting lymphatics, which caused significant symptomatic improvement in oozing of blood and fluid, which had been present since childhood in both patients. However, we observed a recurrence in the second patient after six months.

Nurses' Participation in Clinical and Administrative Decisions in Different Types of Hospital Units.

OBJECTIVE: This study explored the types of decisions and differences in decision making that nurses made in different types of hospital units. BACKGROUND: The relationship between nurses' participation in decision making and the different types of hospital units where they work is not well understood. METHODS: Nurses' participation in decision making was explored using the Participation in Decision Activities Questionnaire. The final sample included 307 nurses in 24 nursing units in 6 hospitals. RESULTS: Nurses overall participated more in clinical than administrative decisions, and there were significant differences based on unit type. Critical care nurses had the highest and general care units the lowest levels of participation in decision making. CONCLUSIONS: Nurses in critical care units participated in higher amounts and at higher levels of clinical decisions overall than either intermediate or general care units. Nurse leaders should determine barriers to decision making in general care units and explore mechanisms to increase participation by clinical nurses.

Culled banana resistant starch-soy protein isolate conjugate based emulsion enriched with astaxanthin to enhance its stability.

The conjugates of biomacromolecules such as proteins and polysaccharides have potential to stabilize the emulsion system and encapsulate valuable bioactive compounds for biofortification in food systems. In this study, native banana starch (NBS) was isolated from green culled banana and modified into resistant starch (type III) by lintnerization followed by autoclaving-cooling process, resulting in lintnerized-autoclaved banana starch (LABS). Soy protein isolate (SPI) was used for developing the polysaccharide-protein conjugates i.e. LABS-SPI conjugate and used as wall material to stabilize the oil-in-water emulsion system. LABS-SPI conjugate emulsions were subjected to in vitro digestion model and oxidative stability evaluation. Furthermore, the emulsion system was enriched with astaxanthin and evaluated for its stability. The chemical finger printing of LABS-SPI conjugates showed stretching in immine and enaminol group of Schiff's bases, the CN stretching of Amadori product. During in vitro digestion LABS-SPI conjugate emulsion showed that the presence of resistant starch had an influence on the droplet digestion process and significantly (p < 0.05) lower free fatty acid release compared to emulsions stabilized by SPI alone. LABS-SPI conjugate emulsion system demonstrated higher stability of astaxanthin at storage temperatures (6, 20 and 37 °C), and can be used for biofortification of food and pharmaceutical formulations.

Correlation of Hormonal Profile and Lipid Levels with Female Adult Acne in a Tertiary Care Center of Nepal.

BACKGROUND: Acne beyond 25 years of age is frequently associated with hormonal derangement in women. Hormonal association provides the impetus for hormonal therapy as well as underpins the need for blood investigations in this population. Hence, we aim to estimate the presence of hormonal derangement and lipid alteration in female adult acne. METHODS: A prospective, observational study was conducted in Dhulikhel Hospital from July 2015 to February 2016. Females older than 25 years with acne were taken in the study after informed consent. Total 100 patients were enrolled after sample size estimation. Hormonal paneland lipid profile were measured. Hormones tested were androgens, C-peptide and thyroid stimulating hormone.Data analysis was done with SPSS-23. Bivariate analysis was done by chi-square test for categorical data. RESULTS: In this study, majority of patients were younger than 30 years (70.5%) and perioral area most commonly involved. Hormonal alteration was seen in 37.2% patients, among which17.9% had hyperandrogenism, 15.4% had abnormal thyroid level and 10.3% had high C-peptides respectively. Lipid profile was altered in 15.4% patients. Hormonal alteration had significant association with irregular menstruation (P<0.05) but not acne severity. CONCLUSIONS: We observed hormonal alteration frequently in females with adult acne, which comprised of various hormonal parameters including hyperandrogenism.Hormonal alteration reflects deranged metabolic milieu and we suggest that wide hormonal panel should be done in female adult acne. Relationship of hormones with menstrual irregularity but not with acne severity, suggest that clinical symptoms should lead hormonal investigations in all grades of acne.

Obesity and Falls in a Prospective Study of Older Men: The Osteoporotic Fractures in Men Study.

OBJECTIVE: The aim of this study is to evaluate fall rates across body mass index (BMI) categories by age group, considering physical performance and comorbidities. METHOD: In the Osteoporotic Fractures in Men (MrOS) study, 5,834 men aged ≥65 reported falls every 4 months over 4.8 (±0.8) years. Adjusted associations between BMI and an incident fall were tested using mixed-effects models. RESULTS: The fall rate (0.66/man-year overall, 95% confidence interval [CI] = [0.65, 0.67]) was lowest in the youngest, normal weight men (0.44/man-year, 95% CI = [0.41, 0.47]) and greatest in the oldest, highest BMI men (1.47 falls/man-year, 95% CI = [1.22, 1.76]). Obesity was associated with a 24% to 92% increased fall risk in men below 80 ( ptrend ≤ .0001, p for interaction by age = .03). Only adjustment for dynamic balance test altered the BMI-falls association substantially. DISCUSSION: Obesity was independently associated with higher fall rates in men 65 to 80 years old. Narrow walk time, a measure of gait stability, may mediate the association.

Association of 3D Geometric Measures Derived From Quantitative Computed Tomography With Hip Fracture Risk in Older Men.

We investigated the associations of 3D geometric measures and volumetric bone mineral density (vBMD) of the proximal femur assessed by quantitative computed tomography (QCT) with hip fracture risk among elderly men. This study was a prospective case-cohort design nested within the Osteoporotic Fractures in Men Study (MrOS) cohort. QCT scans of 230 men (65 with confirmed hip fractures) were evaluated with Mindways' QCTPRO-BIT software. Measures that are indicative of bone strength for the femoral neck (FN) and for the trochanteric region (TR) were defined. Bending strength measures were estimated by minimum section modulus, buckling strength by buckling ratio, and a local thinning index (LTI). Integral and trabecular vBMD measures were also derived. Areal BMD (aBMD) of the total proximal femur from dual-energy X-ray absorptiometry (DXA) is presented for comparison. Associations of skeletal measures with incident hip fracture were estimated with hazard ratios (HR) per standard deviation and their 95% confidence intervals (CI) from Cox proportional hazard regression models with adjustment for age, body mass index (BMI), site, and aBMD. Men with hip fractures were older than men without fracture (77.1 ± 6.0 years versus 73.3 ± 5.7 years, p < 0.01). Age, BMI, and site-adjusted HRs were significant for all measures except TR_LTI. Total femural BMD by DXA (HR = 4.9, 95% CI 2.5-9.9) and QCT (HR = 5.5, 95% CI 2.5-11.7) showed the strongest association followed by QCT FN integral vBMD (HR = 3.6, 95% CI 1.8-6.9). In models that additionally included aBMD, FN buckling ratio (HR = 1.9, 95% CI 1.1-3.2) and trabecular vBMD of the TR (HR = 2.0, 95% CI 1.2-3.4) remained associated with hip fracture risk, independent of aBMD. QCT-derived 3D geometric indices of instability of the proximal femur were significantly associated with incident hip fractures, independent of DXA aBMD. Buckling of the FN is a relevant failure mode not entirely captured by DXA. Further research to study these relationships in women is warranted. © 2016 American Society for Bone and Mineral Research.

Higher 25(OH)D2 is associated with lower 25(OH)D3 and 1,25(OH)2D3.

CONTEXT: Despite common use of supplemental vitamin D2 in clinical practice, the associations of serum vitamin D2 concentrations with other vitamin D metabolites and total vitamin D are unclear. OBJECTIVE: The aim of the study was to measure vitamin D2 and D3 levels and examine their associations with each other and with total vitamin D. DESIGN: We performed a cross-sectional analysis of 679 randomly selected participants from the Osteoporotic Fractures in Men Study. 25-Hydroxyvitamin D2 [25(OH)D2], 25(OH)D3, 1,25-dihydroxyvitamin D2 [1,25(OH)2D2], and 1,25(OH)2D3 were measured using liquid chromatography-tandem mass spectrometry and were summed to obtain total 25(OH)D and 1,25(OH)2D. Associations between all metabolites (D2, D3, and total levels) were examined using Wilcoxon rank-sum tests and Spearman correlations. RESULTS: 25(OH)D2 and 1,25(OH)2D2 were detectable in 189 (27.8%) and 178 (26.2%) of the men, respectively. Higher 25(OH)D2 levels did not correlate with higher total 25(OH)D (r = 0.10; P = .17), although median total 25(OH)D was slightly higher in those with detectable vs undetectable 25(OH)D2 (25.8 vs 24.3 ng/mL; P < .001). 25(OH)D2 was not positively associated with total 1,25(OH)2D levels (r = -0.11; P = .13), and median 1,25(OH)2D level was not higher in those with detectable vs undetectable 25(OH)D2. Higher 25(OH)D2 was associated with lower 25(OH)D3 (r = -0.35; P < .001) and 1,25(OH)2D3 (r = -0.32; P < .001), with median levels of both D3 metabolites 18-35% higher when D2 metabolites were undetectable. CONCLUSIONS: In a cohort of older men, 25(OH)D2 is associated with lower levels of 25(OH)D3 and 1,25(OH)2D3, suggesting that vitamin D2 may decrease the availability of D3 and may not increase calcitriol levels.

Alternate donor hematopoietic cell transplantation (HCT) in non-Hodgkin lymphoma using lower intensity conditioning: a report from the CIBMTR.

We analyzed the outcomes of 248 (61% male) adult recipients of HLA-matched unrelated and HLA-mismatched related donor hematopoietic cell transplantation (HCT) for non-Hodgkin lymphoma (NHL) after reduced or lower intensity conditioning (RIC), reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) from 1997 to 2004. Median age was 52 (range: 18-72 years); 31% had a Karnofsky performance score <90. Follicular NHL (43%) was the major histology. Incidence of grades II-IV acute graft-versus-host disease (aGVHD) was 43% at 100 days; and chronic GVHD (cGVHD) was 44% at 3 years. Treatment-related mortality (TRM) at 100 days was 24%. Three-year overall survival (OS) and progression-free survival (PFS) were 41% and 32%, respectively. In multivariate analysis, use of antithymocyte globulin (ATG) and HLA mismatch were associated with increased TRM. High-grade histology, ATG use, and chemotherapy resistance were associated with lower PFS. Older age, shorter interval from diagnosis to HCT, non-total body irridiation (TBI) conditioning regimens, ex vivo T cell depletion, and HLA-mismatched unrelated donors were associated with mortality. GVHD did not influence relapse or PFS. Older age, aggressive histology, and chemotherapy resistance correlated with poorer survival. For selected patients with NHL, lack of an available sibling donor should not be a barrier to allogeneic HCT.

Outcome of patients with IgD and IgM multiple myeloma undergoing autologous hematopoietic stem cell transplantation: a retrospective CIBMTR study.

INTRODUCTION: Immunoglobulin D (IgD) and IgM multiple myeloma represent uncommon immunoglobulin isotypes, accounting for 2% and 0.5% of cases, respectively. Limited information is available regarding the prognosis of these isotypes, but they have been considered to have a more aggressive course than the more common immunoglobulin G (IgG) and IgA isotypes. In particular, the outcome after autologous hematopoietic stem cell transplantation (auto-HCT) has not been well defined. PATIENTS AND METHODS: Using the Center for International Blood and Marrow Transplant Research (CIBMTR) database, we identified 36 patients with IgD and 11 patients with IgM myeloma among 3578 myeloma patients who received intensive therapy and auto-HCT over a 10-year period. RESULTS: The progression-free and overall survival probabilities at 3 years were 38% (95% CI, 21%-56%) and 69% (95% CI, 51%-84%) for IgD myeloma, and 47% (95% CI, 17%-78%) and 68% (95% CI, 36%-93%), respectively, for IgM disease. Although formal statistical analysis was limited by the small sample size, these results were comparable to those for IgG and IgA patients autografted during the same time period. Transplantation-related mortality and disease relapse/progression of myeloma were also similar for all isotypes. CONCLUSION: This analysis demonstrates comparable outcomes in all immunoglobulin isotypes. Therefore, auto-HCT should be offered to eligible patients with IgD and IgM myeloma.

Outcome of transplantation for myelofibrosis.

Myelofibrosis is a myeloproliferative disorder incurable with conventional strategies. Several small series have reported long-term disease-free survival (DSF) after allogeneic hematopoietic cell transplantation (HCT). In this study, we analyze the outcomes of 289 patients receiving allogeneic transplantation for primary myelofibrosis between 1989 and 2002, from the database of the Center for International Bone Marrow Transplant Research (CIBMTR). The median age was 47 years (range: 18-73 years). Donors were HLA identical siblings in 162 patients, unrelated individuals in 101 patients, and HLA nonidentical family members in 26 patients. Patients were treated with a variety of conditioning regimens and graft-versus-host disease (GVHD) prophylaxis regimens. Splenectomy was performed in 65 patients prior to transplantation. The 100-day treatment-related mortality was 18% for HLA identical sibling transplants, 35% for unrelated transplants, and 19% for transplants from alternative related donors. Corresponding 5-year overall survival (OS) rates were 37%, 30%, and 40%, respectively. DFS rates were 33%, 27%, and 22%, respectively. DFS for patients receiving reduced-intensity transplants was comparable: 39% for HLA identical sibling donors and 17% for unrelated donors at 3 years. In this large retrospective series, allogeneic transplantation for myelofibrosis resulted in long-term relapse-free survival (RFS) in about one-third of patients.
