We used a validated In-house genotyping assay to characterize non-B HIV-1 and to determine drug resistance mutations among treatment-naive patients. Methods: Plasma samples from 105 HIV-1 infected drug-naive adult patients attending a tertiary hospital Jos, Nigeria were subjected to HIV-1 RNA extraction, reverse transcription amplification, and population-based sequencing of the partial pol gene on the ABI 3130xl genetic analyzer. Subtyping and phylogenetic analyses were performed by REGA Subtyping Tool v2.0 and MEGA v5.0 respectively. Drug resistance profiles were evaluated according to IAS-USA 2013 drug resistance mutations list. Result: One hundred samples (95.2%) were successfully genotyped. The distribution of the non-B HIV-1 subtypes were;CRF02_AG-48%, G-41.0%, CRF06_cpx-6.0%, and A-5.0%. Ten percent of the isolates had at least one major drug resistance mutation in the pol gene. The drug-class specific resistance prevalences were 6.0% for NRTIs;M41L-1.0%, K65KR-1.0%, M184IM-1.0%, M184V-2.0%, and T215ADNT-1%, 8.0% for NNRTIs;K103N-2%, 1.0% for K101E, E138A, G190A, P225HP, Y181I, Y188L, Y181C including protease inhibitors’ Q58E (1.0%). Conclusion: HIV-1 was heterogeneously distributed;CRF02_AG and G predominate and some known major mutations associated with NRTIs and NNRTIs were determined. The In-house assay is suitable for both characterization of non-B HIV-1 subtypes and detection of drug resistance at a significant lower cost than available commercial genotyping assays. This finding underscores the need to consider use of low-cost In-house genotyping assay as an alternative in resource-limited settings with non-B HIV-1 epidemic.展开更多

Patient advocacy is essential in providing individualized care and improving health outcomes. With the recent implementation of the Affordable Care Act, the patient advocacy concept requires further exploration. Published literature involving patient advocacy’s history, uses, definition, past analyses and nursing perceptions were examined. Outcomes of this literature review lead to further examining patient advocacy and how it is applied to culturally diverse patient populations, patient advocacy in nursing curricula and related research. Overall study results indicate that patient advocacy is associated with enhanced health encounters that include nurses presenting patients with understandable healthcare options and supporting patients with their healthcare preference. Although, this review identified positive outcomes of patient advocacy, nursing research must be directed toward creating a patient advocacy definition and measuring advocacy from a patient’s perspective. There is also a need for nursing leaders to consider placing a higher emphasis on cultural awareness research and education due to an increased rate of culturally diverse patients now seeking care through the Affordable Care Act.展开更多

We aimed to study the race specifi c association between the dependent coverage provision of the Affordable Care Act(ACA) and changes in young adults' usage of emergency department services for psychiatric diagnoses.METHODS: We utilized a Quasi-Experimental analysis of ED use in California from 2009–2011 for behavioral health diagnoses of individuals aged 19 to 31 years. Analysis used a difference-indifferences approach comparing those targeted by the ACA dependent provision(19–25 years) and those who were not(27 to 31 years), evaluating changes in ED visit rates per 1 000 in California. Primary outcomes measured included the quarterly ED visit rates with any psychiatric diagnosis. Subgroups were analyzed for differences based on race and gender.RESULTS: The ACA dependent provision was associated with 0.05 per 1 000 people fewer psychiatric ED visits among the treatment group(19–25 years) compared to the control group(27–31 years). Hispanics and Asian/Pacific Islanders were the only racial subgroups who did not see this significant reduction and were the only racial subgroups that did not see significant gains in the proportion of psychiatric ED visits covered by private insurance.CONCLUSION: The ACA dependent provision was associated with a modest reduction in the growth rate of ED use for psychiatric reasons, however, racial disparities in the effect of this provision exist for patients of Hispanic and Asian/Pacifi c Islander racial groups.展开更多

Under the requirement of ＂Construction of 10 Million Units in 2011＂ from the central government, the affordable housing has started its nationwide building. Medium-sized cities are facing different developing periods but applying same housing policy as big cities. The paper examines the economic and social condition of the case city to find out the housing problems. It concludes that houses are affordable in these medium-sized cities, but housing policies are not implemented well. The paper proposed that housing affordability in medium-sized city is not about quantity but about quality. To keep houses affordable in these medium-sized cities, housing market, legislation, urban planning, public participation and intensive developments are all important.展开更多

Housing is the sing...The building construction industry is a major contributor of environmental pollution, with high levels of energy consumption and greenhouse gas emissions, all of which contribute to climate change. Housing is the single largest subsector of the construction industry. It is also a basic need associated with social and economic benefits, and its demand in most emerging economies is substantial. Hence it is a sector with significant potential not to mitigate just the negative impact of climate change on buildings and people, but also to reduce the impact of the construction industry on the natural environment. Green buildings technology has advanced greatly in recent years, but most “high performance” green buildings are capital intensive, often with high-tech applications that are not in easy reach of the mass housing market. In the developing country context, where huge segments of the population lack access to essential services or housing, the green buildings approach to addressing climate change is perceived to be largely unaffordable. For green technology to be adopted in poorer nations and have scalable impact, it will have to be low-cost and affordable. According to a 2010 report, buildings in the commercial, office and hospitality sectors are poised to grow at 8% annually over the next 10 years in India. While the retail sector has been growing rapidly at 8% per annum, the residential sector has seen growth of 5% per annum during this period. It is estimated that over 70 million New Urban Housing Units will be required over the next 20 Years.展开更多

Testing local surface water is an exciting way to engage freshman undergraduates in research which shows them the importance of protecting their communities and environment. Two affordable methods: a Colorimeter and Ion-Selective Probe were used to analyze nitrate, phosphate and ammonia levels in local surface water samples. The samples were collected from the Muskingum River which runs through Southeastern Ohio (Muskingum County) and were collected at 2 mile increments. We believe that this set of experiments would be beneficial if implemented into a college freshman level chemistry lab, thereby, promoting self-awareness of water safety, eco-system safety and community involvement. In addition, the students will learn how our environment is effected by our actions when we neglect to properly monitor the type of pollutants we allow into our water ways.展开更多

Solar energy brings impactful benefits and products that are expected to make homes more reliable, sustainable, and affordable. Thanks to technological advancements like the solar cell, we can gather this energy and turn it into electricity. The construction industry has an exceptional chance of benefiting from this sustainable energy. Many recognised benefits have been spelled forth in the construction industry, such as providing homes with clean energy with no trace of ozone depleting material emission. There are many people in Nigeria who are not linked to the public electric grid, and the energy sector produces and generates less than 58% of the entire amount of energy required. As stated in the Nigeria’s National Energy General Plan, the Sustainable Energy programme aims to enhance the country’s use of solar electricity. This paper focuses on the role of solar energy in the provision of sustainable affordable housing in Nigeria. It considers the description, method, and utilisation of solar energy with a focus on residential and commercial buildings.展开更多

Because the situation is comparable to that of other developing nations, it remains a key concern in these countries’ socioeconomic development. Over 52% of Nigeria’s population has been claimed to live in shanties, squatter communities, and informal settlements. This article, therefore, reviews the challenges to the provision of affordable housing in Nigeria and the Sustainable approaches to address them. The article’s findings were based on a thorough examination of the literature. The article’s findings indicated that sustainable approaches for addressing Nigeria’s affordable housing barriers may best be examined through the economic, ecological, social, institutional, and technical factors. The paper urges the present regime, investors, lawmakers, and private developers in Nigeria to implement these approaches for affordable housing provision. The findings from this article will add to the current body of knowledge by providing important information on affordable housing provision and re-directing research interest towards affordable housing in Nigeria and other developing countries.展开更多

This is felt no more so than in developing countries which have experienced disproportionate levels of demand due to their innate vulnerability. Many current approaches to housing delivery in developing countries continue to utilize inappropriate construction methods and implementation procedures that are often problematic and unsustainable. As such affordability and sustainability are now vital considerations in the international development debate for housing the poor in developing countries in order to meet the long term sustainable development goals and needs of housing inhabitants. This paper utilized an extensive scoping study to examine the various facets impacting on design decision making relative to sustainable and affordable housing delivery in developing country contexts. Aspects of affordability, sustainability, design decision making, appropriate technology use, cultural awareness, as well as current barriers to affordable and sustainable construction in developing countries are examined in detail. Results highlighted the capability of indigenous knowledge, skills and materials as well as selected appropriate technology transfer and cultural awareness by foreign bodies can be utilized in innovative ways in addressing current housing needs in many developing country contexts.展开更多

文摘Background: The introduction of antiretroviral (ARV) in resource-limited settings has increased life expectancy among non-B HIV-1 infected individuals. We used a validated In-house genotyping assay to characterize non-B HIV-1 and to determine drug resistance mutations among treatment-naive patients. Methods: Plasma samples from 105 HIV-1 infected drug-naive adult patients attending a tertiary hospital Jos, Nigeria were subjected to HIV-1 RNA extraction, reverse transcription amplification, and population-based sequencing of the partial pol gene on the ABI 3130xl genetic analyzer. Subtyping and phylogenetic analyses were performed by REGA Subtyping Tool v2.0 and MEGA v5.0 respectively. Drug resistance profiles were evaluated according to IAS-USA 2013 drug resistance mutations list. Result: One hundred samples (95.2%) were successfully genotyped. The distribution of the non-B HIV-1 subtypes were;CRF02_AG-48%, G-41.0%, CRF06_cpx-6.0%, and A-5.0%. Ten percent of the isolates had at least one major drug resistance mutation in the pol gene. The drug-class specific resistance prevalences were 6.0% for NRTIs;M41L-1.0%, K65KR-1.0%, M184IM-1.0%, M184V-2.0%, and T215ADNT-1%, 8.0% for NNRTIs;K103N-2%, 1.0% for K101E, E138A, G190A, P225HP, Y181I, Y188L, Y181C including protease inhibitors’ Q58E (1.0%). Conclusion: HIV-1 was heterogeneously distributed;CRF02_AG and G predominate and some known major mutations associated with NRTIs and NNRTIs were determined. The In-house assay is suitable for both characterization of non-B HIV-1 subtypes and detection of drug resistance at a significant lower cost than available commercial genotyping assays. This finding underscores the need to consider use of low-cost In-house genotyping assay as an alternative in resource-limited settings with non-B HIV-1 epidemic.

文摘The nurse-patient relationship is centered on patient advocacy. Patient advocacy is essential in providing individualized care and improving health outcomes. With the recent implementation of the Affordable Care Act, the patient advocacy concept requires further exploration. Published literature involving patient advocacy’s history, uses, definition, past analyses and nursing perceptions were examined. Outcomes of this literature review lead to further examining patient advocacy and how it is applied to culturally diverse patient populations, patient advocacy in nursing curricula and related research. Overall study results indicate that patient advocacy is associated with enhanced health encounters that include nurses presenting patients with understandable healthcare options and supporting patients with their healthcare preference. Although, this review identified positive outcomes of patient advocacy, nursing research must be directed toward creating a patient advocacy definition and measuring advocacy from a patient’s perspective. There is also a need for nursing leaders to consider placing a higher emphasis on cultural awareness research and education due to an increased rate of culturally diverse patients now seeking care through the Affordable Care Act.

文摘The building construction industry is a major contributor of environmental pollution, with high levels of energy consumption and greenhouse gas emissions, all of which contribute to climate change. Housing is the single largest subsector of the construction industry. It is also a basic need associated with social and economic benefits, and its demand in most emerging economies is substantial. Hence it is a sector with significant potential not to mitigate just the negative impact of climate change on buildings and people, but also to reduce the impact of the construction industry on the natural environment. Green buildings technology has advanced greatly in recent years, but most “high performance” green buildings are capital intensive, often with high-tech applications that are not in easy reach of the mass housing market. In the developing country context, where huge segments of the population lack access to essential services or housing, the green buildings approach to addressing climate change is perceived to be largely unaffordable. For green technology to be adopted in poorer nations and have scalable impact, it will have to be low-cost and affordable. According to a 2010 report, buildings in the commercial, office and hospitality sectors are poised to grow at 8% annually over the next 10 years in India. While the retail sector has been growing rapidly at 8% per annum, the residential sector has seen growth of 5% per annum during this period. It is estimated that over 70 million New Urban Housing Units will be required over the next 20 Years.

The construction industry has an exceptional chance of benefiting from this sustainable energy. Many recognised benefits have been spelled forth in the construction industry, such as providing homes with clean energy with no trace of ozone depleting material emission. There are many people in Nigeria who are not linked to the public electric grid, and the energy sector produces and generates less than 58% of the entire amount of energy required. As stated in the Nigeria’s National Energy General Plan, the Sustainable Energy programme aims to enhance the country’s use of solar electricity. This paper focuses on the role of solar energy in the provision of sustainable affordable housing in Nigeria. It considers the description, method, and utilisation of solar energy with a focus on residential and commercial buildings.
文摘Despite multiple schemes implemented by various governments around the country, affordable housing remains elusive to the average Nigerian. Because the situation is comparable to that of other developing nations, it remains a key concern in these countries’ socioeconomic development. Over 52% of Nigeria’s population has been claimed to live in shanties, squatter communities, and informal settlements. This article, therefore, reviews the challenges to the provision of affordable housing in Nigeria and the Sustainable approaches to address them. The article’s findings were based on a thorough examination of the literature. The article’s findings indicated that sustainable approaches for addressing Nigeria’s affordable housing barriers may best be examined through the economic, ecological, social, institutional, and technical factors. The paper urges the present regime, investors, lawmakers, and private developers in Nigeria to implement these approaches for affordable housing provision. The findings from this article will add to the current body of knowledge by providing important information on affordable housing provision and re-directing research interest towards affordable housing in Nigeria and other developing countries.
文摘Housing affordability measurement is a recurring subject in planning literature. Research evidence suggests that in planning for affordable housing, planners typically apply the normative (ratio and residual income) measures to all variants of affordability stress. Hence, proffering intervention strategies that often fail to address peculiar situations in their towns. This systematic review synthesizes empirical evidence in the literature relating to various applications of housing affordability measurement approaches. To ascertain the various application fields/domains, present findings, specify relevant literature gaps, and propose future research themes. The review findings demonstrate that the accurateness of conclusions reached, about the severity of the housing affordability problem is highly dependent on the measurement approach used. The study concludes that the application of appropriate methods to specific situations leads to better planning outcomes.

文摘Current demand for housing worldwide has reached unprecedented levels due to factors such as human population growth, natural disasters and conflict. This is felt no more so than in developing countries which have experienced disproportionate levels of demand due to their innate vulnerability. Many current approaches to housing delivery in developing countries continue to utilize inappropriate construction methods and implementation procedures that are often problematic and unsustainable. As such affordability and sustainability are now vital considerations in the international development debate for housing the poor in developing countries in order to meet the long term sustainable development goals and needs of housing inhabitants. This paper utilized an extensive scoping study to examine the various facets impacting on design decision making relative to sustainable and affordable housing delivery in developing country contexts. Aspects of affordability, sustainability, design decision making, appropriate technology use, cultural awareness, as well as current barriers to affordable and sustainable construction in developing countries are examined in detail. Results highlighted the capability of indigenous knowledge, skills and materials as well as selected appropriate technology transfer and cultural awareness by foreign bodies can be utilized in innovative ways in addressing current housing needs in many developing country contexts.

文摘The use of low-cost depth imaging sensors is investigated to automate plant pathology tests.Spatial evolution is explored to discriminate plant resistance through the hypersensitive reaction involving cotyledon loss.A high temporal frame rate and a protocol operating with batches of plants enable to compensate for the low spatial resolution of depth cameras.Despite the high density of plants,a spatial drop of the depth is observed when the cotyledon loss occurs.We introduce a small and simple spatiotemporal feature space which is shown to carry enough information to automate the discrimination between batches of resistant(loss of cotyledons)and susceptible plants(no loss of cotyledons)with 97%accuracy and with a timing 30 times faster than for human annotation.The robustness of the method-in terms of density of plants in the batch and possible internal batch desynchronization-is assessed successfully with hundreds of varieties of Pepper in various environments.A study on the generalizability of the method suggests that it can be extended to other pathosystems and also to segregating plants,i.e.,intermediate state with batches composed of resistant and susceptible plants.The imaging system developed,combined with the feature extraction method and classification model,provides a full pipeline with unequaled throughput and cost efficiency by comparison with the state-of-the-art one.This system can be deployed as a decision-support tool but is also compatible with a standalone technology where computation is done at the edge in real time.
文摘We hereby comment on the interesting systematic review by Grewal et al where they have provided an overall picture of the current status of available tele-health programs in the United States with emphasis on the Amazon Clinic.Their analysis is an appreciable effort in discovering the features available and features lacking in these tele-health programs.The concept of tele-health originated to curtail the need for physical attendance of patients at health clinics,and has been beneficial during the coronavirus disease 2019 pandemic.We implore that the pearls and pitfalls of these programs have to be understood by policymakers prior to forming a consensus regarding the availability,accessibility and affordability of these programs as methods of healthcare delivery.Unrestricted proliferation of tele-health programs in their current form may pose threats to patient and provider safety and medicolegal liability.However,patients and providers must work together to improve them to meet their expectations and enable them to provide the best care for the ailing public.
