ABSTRACTZika virus (ZIKV) caused significant public health concern, because of its association with congenital malformations, neurological disorders in adults and, more recently, with deaths. Considering the necessity to mitigate the cases ZIKV-associated diseases, antiviral interventions against this virus are an urgent necessity. Sofosbuvir, a drug in clinical use against Hepatitis C Virus (HCV), is among the FDA-approved substances endowed with anti-ZIKV activity. In this work, we further investigated the in vivo activity of sofosbuvir against ZIKV. Neonatal Swiss mice were infected with ZIKV (2 x 107 PFU) and treated with sofosbuvir at 20 mg/kg/day, a concentration compatible with pre-clinical development of this drug. We found that sofosbuvir reduced acute levels of ZIKV from 60 to 90 % in different anatomical compartments, such as in blood plasma, spleen, kidney and brain. Early treatment with sofosbuvir doubled the percentage and time of survival of ZIKV-infected animals, despite the aggressive virus challenge assayed and also prevented the acute neuromotor impairment triggered by the virus. On the long-term behavior analysis of ZIKV-associated sequelae, sofosbuvir prevented loss of hippocampal- and amygdala-dependent memory. Our results point out that sofosbuvir inhibits ZIKV replication in vivo, which is consistent with the prospective necessity of antiviral drugs to treat ZIKV-infected individuals.

In Bangladesh, iron deficiency is the most common cause of anemia and remains a significant public health concern. Being a high anemia prevalent country, numerous efforts have been made to confront the issue especially among women and children by both local and international actors. Though the situation has substantially improved in recent years, a staggering number of adult women are currently living with anemia. The etiology of anemia is a multifactorial problem and has been proposed to be associated with various household, societal, economic, cultural factors apart from dietary habits. However, evidence regarding the household arrangements and socioeconomic determinants of anemia is scarce, especially in the context of Bangladesh. To this end, we utilized the 2011 demographic and health survey data to explore the association between anemia status and selected demographic, socioeconomic, and household characteristics. Our result showed significant correlation of anemia with both sociodemographic and household characteristics. Among the sociodemographic variables the following were found to be significantly associated with anemia status: age (p=0.014; OR = 1.195; 95% CI = 1.036–1.378) and microcredit membership (p=0.014; OR = 1.19; 95% CI = 1.037–1.386). Regarding the household arrangements, women utilizing biomass fuel for cooking (p<0.019; OR = 1.82; 95% CI = 0.981–2.460) were more likely to be anemic.

Abstract Background: Anemia is an underdiagnosed, significant public health concern afflicting &gt;2 billion people worldwide. The detrimental effects of tissue oxygen deficiency on the cardiovascular system and concurrent appearance of anemia with numerous high-risk disorders highlight the importance of clinical screening. Currently there is no universally accepted, clinically applicable, noninvasive hemoglobin/hematocrit screening tool. The need for such a device has prompted an investigation into a breadth of techniques. Methods: A synopsis of the literature and current directions of research in noninvasive total hemoglobin measurement was collected. Contributions highlighted in this review are limited to those studies conducted with a clinical aspect, and most include in vivo patient studies. Results: The review of potential techniques presented here includes optoacoustic spectroscopy, spectrophotometric imaging, diffuse reflectance spectroscopy, transcutaneous illumination, electrical admittance plethysmography, and photoplethysmography. The technological performance, relative benefits of each approach, potential instrumentation design considerations, and future directions are discussed in each subcategory. Conclusions: Many techniques reviewed here have shown excellent accuracy, sensitivity, and specificity in measuring hemoglobin/hematocrit, thus in the near future a new clinically viable tool for noninvasive hemoglobin/hematocrit monitoring will likely be widely used for patient care. Limiting factors in clinical adoption will likely involve technology integration into the current standard of care in each field routinely dealing with anemia.

The growing population of older adults with depression is a significant public health concern, and effective treatments are necessary. Mindfulness meditation intervention offers effective treatment for depression, but little research has been conducted on the older population. This study aimed to evaluate if the combination of the Internet Mindfulness Meditation Intervention (IMMI) plus iMINDr application improves well-being in older adults with depressive symptoms. Potential participants were recruited online. IMMI included a one-hour online session once a week, a daily 30-minute home practice of guided meditation using the iMINDr app, and a workbook. Measures were collected online before and after the six-week intervention period. Online session adherence was tracked. Thirty-eight participants completed all study requirements and are included in the analysis. Participants showed clinically and statistically significant improvements in depression symptoms, well-being, positive and negative affect, sleep quality, and pain intensity. Participants took 9.9 ± 3.5 weeks to complete the course. High attrition rates mainly were related to participants' motivation to complete the course and stress levels. There were no significant demographic differences between participants and depression symptoms. Potential applications and limitations are discussed. Internet Mindfulness Meditation Intervention (IMMI) was effective in treating depression symptoms in older adults.

Actual Prevalence

People often form perceptions about how prevalent a behavior is in a social group. However, these perceptions can be inaccurate and biased. While persistent undesirable practices in low-income countries have drawn global attention, evidence regarding people’s perception of how prevalent these practices are is scarce. Among those harmful practices, open defecation in India remains a significant public health concern, where it perpetuates the vicious cycle of disease and poverty. In this study, we focus on measuring the perceived prevalence of open defecation among respondents in Bihar, India. We examined the bias in perceived prevalence, which is defined as a pattern of deviation from the actual prevalence of open defecation. Results showed that respondents who defecate in the open overestimate the prevalence of open defecation, whereas those who consistently use toilets underestimate it. This finding suggests a false consensus bias in the perceived prevalence of open defecation. Scholars, policymakers, and program implementers who seek to correct misperceptions about open defecation by broadcasting real prevalence should be aware of biases in the perceived prevalence and address them in behavior change interventions.

Unprecedented and unforeseen highly infectious Coronavirus Disease 2019 (COVID-19) has become a significant public health concern for most of the countries worldwide, including Nepal, and it is spreading rapidly. Undoubtedly, every nation has taken maximum initiative measures to break the transmission chain of the virus. This review presents a retrospective analysis of the COVID-19 pandemic in Nepal, analyzing the actions taken by the Government of Nepal (GoN) to inform future decisions. Data used in this article were extracted from relevant reports and websites of the Ministry of Health and Population (MoHP) of Nepal and the WHO. As of January 22, 2021, the highest numbers of cases were reported in the megacity of the hilly region, Kathmandu district (population = 1,744,240), and Bagmati province. The cured and death rates of the disease among the tested population are ~98.00 and ~0.74%, respectively. Higher numbers of infected cases were observed in the age group 21–30, with an overall male to female death ratio of 2.33. With suggestions and recommendations from high-level coordination committees and experts, GoN has enacted several measures: promoting universal personal protection, physical distancing, localized lockdowns, travel restrictions, isolation, and selective quarantine. In addition, GoN formulated and distributed several guidelines/protocols for managing COVID-19 patients and vaccination programs. Despite robust preventive efforts by GoN, pandemic scenario in Nepal is, yet, to be controlled completely. This review could be helpful for the current and future effective outbreak preparedness, responses, and management of the pandemic situations and prepare necessary strategies, especially in countries with similar socio-cultural and economic status.

Background: Preeclampsia is a major obstetrical health concern, affecting 5-8% of all pregnancies. Hallmarked by hypertension and endothelial dysfunction the origin of the disease remains obscure, though it is generally accepted that placental insufficiency/ischemia is a central cause. In response, the placenta secretes pathogenic factors, in particular the anti-angiogenic protein sFlt-1. Currently, there is no effective therapy for the management of the preeclampsia patient. We have recently produced a novel synthetic peptide based on placental growth factor (PlGF) which is maternally restricted by fusion to the synthetic carrier elastin like polypeptide (ELP). Here, we describe its in vivo pharmacokinetics and biodistribution. Methods: Fluorescently labeled ELP-PLGF was administered i.v. and blood sampled serially to determine clearance kinetics. Long-term pharmacokinetics and biodistribution was performed after subcutaneous administration of labeled peptide. Measurements were made on serially drawn blood, and in the whole animal by in vivo imaging. Results: ELP-PlGF exhibited markedly more favorable pharmacokinetics than the normal half life of PlGF, with a terminal half-life of ~10 hours as opposed to ~30 minutes for PlGF alone. Chronic administration found highest levels accumulating in placenta and kidney (two favorable targets for preeclampsia) and liver. A single subcutaneous administration at 100mg/kg resulted in sustained therapeutic plasma concentrations for over 10 days. Conclusion: These data demonstrate that ELP-PlGF has favorable pharmacokinetic and biodistribution profiles. Previous data suggest ELP-PlGF directly antagonizes sFlt-1 in culture. Future studies to assess the in vivo effectiveness of ELP-PlGF in managing placental ischemia induced hypertension and endothelial dysfunction are currently in progress.

Food allergy is a potentially life-threatening medical condition and a significant public health concern worldwide. The current management consists of strict avoidance of the culprit food and treating any adverse reactions from unintended food ingestion. The increasing prevalence of food allergy encouraged research and clinical trials in the field of specific allergen immunotherapy (AIT) which represents an appealing approach, especially in pediatric age. AIT consists of the gradual administration of growing amounts of the offending allergen in order to induce food desensitization, which is an increase in the threshold for reactivity while continuing on regular exposure to the allergen. AIT can be administered through oral, sublingual, epicutaneous, and subcutaneous routes. Reports on oral immunotherapy (OIT) thus far have been more extensive. The desirable goal is to achieve &quot;post desensitization effectiveness&quot;, that is the ability to introduce food without reaction even after a period of discontinuation of the offending food. Other therapeutic approaches are being studied alongside immunotherapy such as modified proteins, probiotics, Chinese herbal supplements, biologic therapies, and DNA vaccines.
