RESUMO
During public health emergencies, health communication materials to contain the outbreak are needed promptly, which prevents the use of standard approaches for getting feedback from the intended audience. We propose a strategy for rapidly obtaining community feedback on new health communication materials during the public health emergencies. We illustrate this with COVID-19 testing campaign in a Vietnamese-American enclave in the USA. The project included community-based COVID-19 testing and communication activities to increase the awareness of the testing centers and encourage frequent testing. Our strategy involves two main components: (i) use of a research team with an existing trust relationship with the community and that includes researchers from that community and (ii) co-design of communication materials using community-based gatekeepers and a cultural broker. We developed brochures and posters to increase the awareness of the COVID-19 testing services. The cultural broker and community-based partners identified salient message concepts and worked with the researchers to define the objectives and content of the materials, which were then reviewed by the entire team. In lieu of standard pretesting, we relied on feedback on mockups of the materials and subsequent revisions from the community-based gatekeepers and cultural broker. Our strategy strikes a balance between the need to urgently disseminate new materials and the need for community input. One key takeaway is that effective planning for public health emergencies must start long before the crisis occurs.

Fouling behaviour in membrane distillation (MD) processes plays a crucial role in determining their widespread acceptability. Most studies have primarily focused on model organic foulants, such as humic acid (HA) and sodium alginate (SA). This study investigates the fouling of a polytetrafluoroethylene membrane in a direct contact MD (DCMD) using model organics (i.e., HA and SA) and real wastewater. The results indicated that the flux decline (5-60%) was only observed during the initial phase of the operation with model organic foulants. In contrast, real wastewater caused a gradual decline in flux throughout the experiment in both the concentrate (40%) and continuous (90%) modes. The study also found significant differences in the fouling layer morphology, composition, and hydrophobicity between the model organic foulants and real wastewater. Fourier transform infrared spectroscopy findings demonstrated that the fouling layer formed by real wastewater varied significantly from model organics, which primarily comprised of protein-like and polysaccharide-like functional groups. Finally, liquid chromatography-organic carbon detection revealed that the fouling layer of the MD membrane with real wastewater was composed of 40.7% hydrophobic and 59.3% hydrophilic organics. This study suggests that model organics may not accurately reflect real wastewater fouling.

OBJECTIVES: Our principal objectives were to identify the level of adherence and identify the attitudes, beliefs, and behaviors that influence adherence to antihypertensive treatment among Vietnamese patients in New Orleans, Louisiana. METHODS: By partnering with a community health center serving the Vietnamese community in New Orleans, we conducted reviews of 250 medical records of hypertensive patients receiving care there, 3 provider interviews, and 8 patient interviews. Descriptive and thematic analyses were used. RESULTS: The level of treatment nonadherence in our sample population was 20.40%. Findings highlighted several key factors that may contribute to adherence, including easy access to providers, who are culturally competent and have used several strategies to help increase adherence, and the social support network of patients within a close-knit community. Other sociodemographic factors, such as age, sex, and tobacco and alcohol use also may play a role in adherence. CONCLUSIONS: Adherence to antihypertensive treatment among Vietnamese patients in New Orleans was relatively high compared with other ethnic and racial groups in the United States. Further assessment of the characteristics of patients, providers, and the community may improve adherence to other chronic conditions in this population and patients of other ethnicities and races.

This study assessed the methylene blue adsorption using natural and modified mussel shell powders in the aqueous solution. The mussel shell samples were processed in a NaClO solution then modified with sodium dodecyl sulfate and ethylenediaminetetraacetic acid. The characteristics of mussel shell samples before and after modification were demonstrated using infared spectroscopy, thermogravimetric analysis, scanning electron microscopy, nitrogen adsorption/desorption, energy dispersive X-ray, water contact angle, and dynamic light scattering methods. Some factors such as the pH of the medium, adsorption temperature, and adsorption time had a significant effect on the methylene blue adsorption of mussel shell samples. The adsorption isotherm models and kinetics of methylene blue adsorption by mussel shell samples were also studied. A quadratic regression equation was selected with experimental planning following the Box-Behnken model combined with Design Expert 11.1.0.1 software to optimize the methylene blue adsorption process by mussel shell samples. These results open a promising direction for using naturally derived materials to remove organic pollutants from contaminated water.

Introduction: This study aimed to evaluate the treatment outcomes of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) therapy alone or in combination with locoregional brain therapy for advanced EGFR-mutant non-small cell lung cancer (NSCLC) patients with brain metastases. Material and methods: A retrospective study involving 72 advanced EGFR-mutant NSCLC patients with brain metastases at the Vietnam National Cancer Hospital were conducted. Patients were divided into 2 groups: EGFR-TKI (erlotinib) monotherapy and EGFR-TKI combined with locoregional therapy (γ knife surgery - GKS or whole-brain radiation therapy). Evaluation criteria included clinical and laboratory characteristics, central nervous system (CNS) progression time, progression-free survival (PFS), overall survival (OS), T790M mutation rate, and adverse events. Results: Epidermal growth factor receptor tyrosine kinase inhibitor monotherapy patients had better performance status (PS), fewer CNS symptoms, and significantly fewer brain metastases (p < 0.05). Median PFS and OS were 11 and 25 months, respectively, in both groups. Patients with PS 0-1 had longer median PFS (15 months) than those with PS 2 (7 months) (p = 0.039). Exon 19 deletion patients in both groups had longer median OS (26 months) than those with L858R exon 21 (15 months) (p = 0.023). Patients with T790M mutation who received osimertinib after progression had longer median OS (41 months vs. 23 months, p = 0.0001). Median time to CNS progression was 13.9 months (48 patients). Longer time to CNS progression correlated with longer OS (R2 = 0.89). Conclusions: Epidermal growth factor receptor tyrosine kinase inhibitor therapy, with or without locoregional therapy, is effective for advanced EGFR-mutant NSCLC patients with brain metastases. Exon 19 deletion patients had better prognosis.
RESUMO
Antibiotics might build up into the human body by foodstuff metabolism, posing a serious threat to human health and safety. Establishing simple and sensitive technology for quick antibiotic evaluation is thus extremely important. Nanomaterials (or NMTs) with the advantage of possessing merits such as remarkable optical, thermal, mechanical, and electrical capabilities have been highlighted as a piece of the best promising materials for rising new paths in the creation of the future generation biosensors. This paper presents the most recent advances in the use of graphene NMTs-based biosensors to determine antibiotics. Gr-NMTs (or graphene nanomaterials) have been used in the development of a biosensor for the electrochemical signal-transducing process. The rising issues and potential chances of this field are contained to give a plan for forthcoming research orientations. As a result, this review provides a comprehensive evaluation of the nanostructured electrochemical sensing approach for antibiotic residues in various systems. In this review, various electrochemical techniques such as CV, DPV, Stripping, EIS, LSV, chronoamperometry, SWV were employed to determine antibiotics. Additionally, this also demonstrates how graphene nanomaterials are employed to detect antibiotics.

BACKGROUND: Most existing facility assessments collect data on a sample of health facilities. Sampling of health facilities may introduce bias into estimates of effective coverage generated by ecologically linking individuals to health providers based on geographic proximity or administrative catchment. METHODS: We assessed the bias introduced to effective coverage estimates produced through two ecological linking approaches (administrative unit and Euclidean distance) applied to a sample of health facilities. Our analysis linked MICS household survey data on care-seeking for child illness and childbirth care with data on service quality collected from a census of health facilities in the Savanes region of Cote d'Ivoire. To assess the bias introduced by sampling, we drew 20 random samples of three different sample sizes from our census of health facilities. We calculated effective coverage of sick child and childbirth care using both ecological linking methods applied to each sampled facility data set. We compared the sampled effective coverage estimates to ecologically linked census-based estimates and estimates based on true source of care. We performed sensitivity analyses with simulated preferential care-seeking from higher-quality providers and randomly generated provider quality scores. RESULTS: Sampling of health facilities did not significantly bias effective coverage compared to either the ecologically linked estimates derived from a census of facilities or true effective coverage estimates using the original data or simulated random quality sensitivity analysis. However, a few estimates based on sampling in a setting where individuals preferentially sought care from higher-quality providers fell outside of the estimate bounds of true effective coverage. Those cases predominantly occurred using smaller sample sizes and the Euclidean distance linking method. None of the sample-based estimates fell outside the bounds of the ecologically linked census-derived estimates. CONCLUSIONS: Our analyses suggest that current health facility sampling approaches do not significantly bias estimates of effective coverage produced through ecological linking. Choice of ecological linking methods is a greater source of bias from true effective coverage estimates, although facility sampling can exacerbate this bias in certain scenarios. Careful selection of ecological linking methods is essential to minimize the potential effect of both ecological linking and sampling error.

In this paper, we discuss veterinary medicine and its applications in the food industry as well as the risk to the health of humans and animals caused by these residues. We review how the veterinary residues enter and cause some detrimental effects. We also mention two techniques to determine the residue of veterinary medications that exist in food originating from animals, including classic and advanced techniques. Finally, we discuss the potential of various developed methods and compare them with some traditional techniques.

Evidence suggests that despite high knowledge of family planning (FP), unwanted pregnancies and birth rates remain high among young Nigerians. There is a critical gap in understanding the nexus between exposure to FP information and contraception practices among this population. This study aimed to fill this gap and tested a pathway of the impact of media exposure to FP messages on modern contraceptive use. Data came from a 2018 cross-sectional baseline survey of young people aged 15-24 in three urban centers in Nigeria - Lagos, Kaduna, and Kano. This was part of an impact evaluation of a television-based drama designed to improve contraceptive use among young individuals. The study was limited to 777 young men and women who were sexually active. We found evidence of the mediation effect of media exposure to FP messages on partner discussion about FP, which in turn was associated with an increased likelihood of modern contraceptive use. Contraceptive self-efficacy also had positive associations with contraception. Our study elucidated a potential pathway through which media communication programs can significantly contribute to increased modern contraceptive use and underlined the importance of providing young people in Nigeria with opportunities to learn and practice obtaining and using contraception.

Colloidal cesium lead halide perovskite nanocrystals exhibit unique photophysical properties including high quantum yields, tunable emission colors, and narrow photoluminescence spectra that have marked them as promising light emitters for applications in diverse photonic devices. Randomly oriented transition dipole moments have limited the light outcoupling efficiency of all isotropic light sources, including perovskites. In this report we design and synthesize deep blue emitting, quantum confined, perovskite nanoplates and analyze their optical properties by combining angular emission measurements with back focal plane imaging and correlating the results with physical characterization. By reducing the dimensions of the nanocrystals and depositing them face down onto a substrate by spin coating, we orient the average transition dipole moment of films into the plane of the substrate and improve the emission properties for light emitting applications. We then exploit the sensitivity of the perovskite electronic transitions to the dielectric environment at the interface between the crystal and their surroundings to reduce the angle between the average transition dipole moment and the surface to only 14° and maximize potential light emission efficiency. This tunability of the electronic transition that governs light emission in perovskites is unique and, coupled with their excellent photophysical properties, introduces a valuable method to extend the efficiencies and applications of perovskite based photonic devices beyond those based on current materials.
RESUMO
Public stigma is one barrier to accessing behavioral health care among Vietnamese Americans. To explore and identify features of culture and acculturation that influence behavioral health-related stigma, six focus groups were conducted with Vietnamese American participants in three generational groups and eleven key informant interviews were conducted with Vietnamese community leaders, traditional healers, and behavioral health professionals. Data were analyzed using Link and Phelan's (Annu Rev Sociol 27(1):363-385, 2001) work on stigma as an organizing theoretical framework. Findings underline several key cultural and generational factors that intersect to affect perceptions, beliefs, and stigma about mental health treatment. In particular, participants in the youngest groups highlighted that while they recognized the value of mental health services, they felt culturally limited in their access. This appeared to be closely related to intergenerational communication about mental health. The findings suggest avenues for further research as well as interventions to increase mental health treatment access and adherence.

OBJECTIVE: Hyperemesis gravidarum (HG) affects 0.3-3% of pregnant women and is a leading cause of hospitalization in early pregnancy. The aim of the study was to investigate women's treatment and management of HG, as well as the consequences of HG on women's daily life. DESIGN AND SETTING: A cross-sectional study based on a structured telephone interview and an online questionnaire. Participants were recruited by social media and by the Norwegian patient's organization for HG. SUBJECTS: Norwegian women that experienced HG. MAIN OUTCOME MEASURE: Women's perspectives on management and consequences of HG. RESULTS: The study included 107 women. Maternal morbidity was profound; about 3/4 of participants were hospitalized due to HG, and the majority showed clinical signs of dehydration (79%), ketonuria (75%), and >5% weight loss (84%). Antiemetics were used by >90% and frequently prescribed "as needed". Metoclopramide (71%) and meclozine (51%) were most commonly used. Participants described HG as having severe psychosocial consequences and profound impact on daily activities. Almost two out of five reported thoughts of elective abortion, and 8 women had at least one elective pregnancy termination due to HG. Overall, 20 women (19%) changed GPs due to dissatisfaction with HG management. CONCLUSION: Despite the high psychosocial burden and major impact on daily activities, many women with HG reported a lack of support from healthcare professionals and suboptimal management. Greater awareness and knowledge among healthcare professionals is needed to improve care for women with HG. Key Points There is a paucity of studies on management and the consequences of HG on women's daily lives and psychosocial burden. We found that: ⢠Many women described HG as one of their worst life experiences with profound morbidity. ⢠Many women reported suboptimal management of HG and lack of support from healthcare professionals. ⢠Greater understanding of patient perspectives among healthcare professionals is important to improve care and management for HG patients.

Recently, we found that resident myogenic stem satellite cells upregulate a multi-functional secreted protein, semaphorin 3A (Sema3A), exclusively at the early-differentiation phase in response to muscle injury; however, its physiological significance is still unknown. Here we show that Sema3A impacts slow-twitch fiber generation through a signaling pathway, cell-membrane receptor (neuropilin2-plexinA3) â myogenin-myocyte enhancer factor 2D â slow myosin heavy chain. This novel axis was found by small interfering RNA-transfection experiments in myoblast cultures, which also revealed an additional element that Sema3A-neuropilin1/plexinA1, A2 may enhance slow-fiber formation by activating signals that inhibit fast-myosin expression. Importantly, satellite cell-specific Sema3A conditional-knockout adult mice (Pax7CreERT2 -Sema3Afl °x activated by tamoxifen-i.p. injection) provided direct in vivo evidence for the Sema3A-driven program, by showing that slow-fiber generation and muscle endurance were diminished after repair from cardiotoxin-injury of gastrocnemius muscle. Overall, the findings highlight an active role for satellite cell-secreted Sema3A ligand as a key "commitment factor" for the slow-fiber population during muscle regeneration. Results extend our understanding of the myogenic stem-cell strategy that regulates fiber-type differentiation and is responsible for skeletal muscle contractility, energy metabolism, fatigue resistance, and its susceptibility to aging and disease.

The objective of this study was to assess the availability and readiness of the primary health care (PHC) services of commune health centers (CHCs) in Quoc Oai, a rural district of Northern Vietnam based on the World Health Organization's Service Availability and Readiness Assessment (SARA) tool. The study was done in 2 steps. First, the heads of the 21 CHCs of Quoc Oai district were interviewed using SARA, a quantitative survey, and the responses were then validated by direct observations of each facility. The results showed that although the average number of health staffs in each CHC met the national standards (at least 5 staffs per CHC), its allocation within each CHC was not properly met because some CHCs had only 2 health staffs. Several health equipment and facilities were not fully available in many CHCs, and although the majority of the PHC services were available at the CHCs, their readiness remained limited. Several significant correlates between the availability of health care workers and the availability of the facilities and the PHC services were observed, suggesting that they depend upon and affect one another in the health system. Using the SARA-based inventory, the study helps health managers and policy makers to prioritize efforts and allocate resources more appropriately. To be effective, attention should be given to how to make facilities, services, and human resources for health ready for PHC activities-more investment and support from the system (from higher to lower level) and the government.

Health sector decentralization has created an urgent need to strengthen public health management capacity in many countries throughout the developing world. This article describes the establishment of a national management training network in Vietnam that used Project-Based Learning to strengthen management competencies of HIV program workers and linked training to measurable improvement in HIV/AIDS public health program outcomes. Skills were taught using a combination of classroom learning and mentored fieldwork. From 2005 to 2015, 827 HIV/AIDS program managers were trained with this method throughout Vietnam by trainers in 3 regional training centers. A total of 218 applied learning projects were carried out by trainees during this period; 132 resulted in measurable improvements in HIV/AIDS program outputs, and 86 produced well-organized plans for implementing, monitoring, and evaluating HIV/AIDS intervention strategies. Vietnam's management training network represents an important advancement in public health workforce development that helps prepare workers for new roles and responsibilities in a decentralized health system.

Early linkage to HIV care is associated significantly with improved patient outcomes and reduced the risk of HIV transmission. However, delays between HIV diagnosis and registering for care have prevailed in Vietnam. The aim of researchers in this study is to examine linkages to care for individuals newly diagnosed with HIV in 2014, especially to highlight the impact of gender upon these linkages in a Northern Province of Ninh Binh. We collected secondary data of all 125 eligible HIV positive people diagnosed in 2014 and conducted a gender-based descriptive analysis of their registration to care within 6 months. Nineteen in-depth interviews and two focus group discussions were completed. We found that women accounted for one-third of newly diagnosed cases (42/125), but initiated HIV treatment at an earlier stage of HIV disease than men (65% women at stage 1, 2 versus 31% in men). Stigma and discrimination was greater among women while inadequate awareness of treatment was greater for men. Dissatisfaction with HIV testing and counseling and no or passive referral to treatment were other barriers for both the genders for enrolling in care services after diagnosis.

OBJECTIVE: Despite much progress in maternal health service coverage, the quality of care has not seen parallel improvement. This study assessed the quality of antenatal care (ANC), an entry point to the health system for many women. DESIGN: The study used data from recent Service Provision Assessment (SPA) surveys of nationally representative health facilities in Kenya and Namibia. SETTING: Kenya and Namibia represent the situation in much of sub-Saharan Africa, where ANC is relatively common but maternal mortality remains high. PARTICIPANTS: The SPA comprised an inventory of health facilities that provided ANC, interviews with ANC providers and clients, and observations of service delivery. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Quality was measured in terms of structure and process of service provision, and client satisfaction as the outcome of service provision. RESULTS: Wide variations in structural and process attributes of quality of care existed in both Kenya and Namibia; however, better structural quality did not translate to better service delivery process or greater client satisfaction. Long waiting time was a common problem and was generally more serious in hospitals and health centers than in clinics and smaller facilities; it was consistently associated with lower client satisfaction. The study also indicates that the provider's technical preparedness may not be sufficient to provide good-quality services and to ensure client satisfaction. CONCLUSIONS: Findings highlight important program implications, including improving ANC services and promoting their use at health clinics and lower-level facilities, and ensuring that available supplies and equipment are used for service provision.

The residual levels of antibiotics in Vietnamese eggs were monitored from 2014 to 2015. A total of 111 egg packages, distributed by 11 different companies, were collected from supermarkets in Ho Chi Minh City and the levels of 28 antibiotics were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS) screening method. Sixteen samples tested positive for antibiotics; a total of eight compounds (enrofloxacin, ciprofloxacin, norfloxacin, sulfadimethoxine, sulfamethazine, sulfamonomethoxine, tilmicosin and trimethoprim) were detected. Enrofloxacin was detected in eight samples, with two samples exhibiting concentrations exceeding 1,000 µg kg-1. Tilmicosin was detected in three samples at a range of 49-568 µg kg-1. We observed that two of the 11 companies frequently sold antibiotic-contaminated eggs (detection rates of 56 and 60%), suggesting that a number of companies do not regulate the use of antibiotics in egg-laying hens. Our findings indicate that livestock farmers require instruction regarding antibiotic use and that continual antibiotic monitoring is essential in Vietnam.

Knowing one's serostatus is critical in the HIV prevention, care and treatment continuum. This study examines the impact of communication programs on HIV testing in South Africa. Data came from 2204 young men and women aged 16-24 who reported to be sexually active in a population based survey. Structural equation modeling was used to test the directions and causal pathways between communication program exposure, HIV testing discussion, and having a test in the last 12 months. Bivariate and multivariate probit regressions provided evidence of exogeneity of communication exposure and the two HIV-related outcomes. One in three sampled individuals had been tested in the last 12 months. Communication program exposure only had an indirect effect on getting tested by encouraging young people to talk about testing. The study suggests that communication programs may create an environment that supports open HIV-related discussions and may have a long-term impact on behavior change.

Wealth-related disparities in the use of reproductive health services remain a substantial problem in many low- and middle-income countries. Very few studies have attempted to explain such inequalities through decomposition of the contributions made by various individual- and household-level factors. This study aims to: (1) assess the degree of wealth-related inequality and inequity in the use of institutional delivery services in selected low- and middle-income countries, and (2) to explain wealth-related inequity through decomposition by the contributions made by various components, including health insurance coverage. Data come from Demographic and Health Surveys in three countries: Ghana, Rwanda, and the Philippines. Concentration indices are used to calculate inequality and horizontal inequity in service utilization. Multivariate methods are used to decompose inequity. Findings indicate a moderate to high degree of inequity in institutional delivery service use in all study countries. The study provides some evidence of the contribution of health insurance to increased wealth-related inequity in the use of institutional delivery services, although having health insurance was also associated with increased utilization of services. Results suggest that increased health insurance coverage does not automatically translate to lower wealth-related inequity in service utilization. Inequities in service utilization exist if there are still inequities in the health insurance status. The study advocates for expanding health insurance coverage, particularly among the poor to reduce inequity in insurance coverage and increase service utilization.
