Ecology of Eucalyptus aquatica (Myrtaceae), a restricted eucalypt confined to montane swamp (fen) habitat in south-eastern Australia.
The Paddys River Wetlands in the New South Wales Southern Highlands, southwest of Sydney, are characterised by several watercourses with associated swamps (fens), some of which, on Forestry Corporation of NSW land, have been the focus for removal of Pinus radiata wildings by the Penrose Swamps Conservation Group. In this study we map a population of Eucalyptus aquatica trees in one of these swamps perched above Paddys River (latitude 34.65575 o S, longitude 150.21831 o E; 600 m elevation). Eucalyptus aquatica is geographically restricted to the Paddys River area and is listed as a threatened species at state and national levels. New findings on the physical characteristics of the swamp in relation to the bedrock geology, stream geomorphology, peat development and the main native plant species, are presented. The occurrence of clumps of Eucalyptus aquatica appears to be independent of the type or thickness of the growing substrate. Rather it is suggested that a continuous supply of water and the shelter afforded by the narrow valley may be key factors determining the distribution of the trees at the study site. An on-going programme of research is underway to study other occurrences of Eucalyptus aquatica.

As in many developed countries, the very elderly population (ages 85+) is the fastest growing age group in Australia, with far-reaching economic and social consequences. To effectively plan and budget for the income, aged care and health care needs of the very elderly, accurate estimates and projections are required. There are, however, several obstacles relating to the availability and accuracy of very elderly data. Official population estimates at very high ages in Australia have been found to be too high and fluctuate implausibly over time. International and local studies have found large errors in projected very elderly populations, stemming from inaccurate mortality rate forecasts. This thesis aims to create accurate estimates and projections for Australia’s very elderly population at a state and national level. Various methods for estimating very elderly populations from death counts were assessed for accuracy at both a national and state level. While the Human Mortality Database uses such methods to create estimates for many countries, their accuracy has never been assessed for Australia. Furthermore, little is known, locally or internationally, about their performance at a sub-national scale. In this study, the accuracy of various nearly-extinct-cohort methods were assessed at the Australian national and state level by retrospectively applying them to extinct cohorts and comparing the results against those obtained from applying the Extinct Cohort method. Suitable methods were applied to create very elderly population estimates and death rates for Australia from 1972-2012 by sex, state and at single ages 85-110+. The growth, changes in the age-sex composition and the demographic drivers of growth of Australia’s very elderly population were analysed. Based on these estimates, more reliable death rates were calculated, allowing a detailed study of the changing patterns and trends in Australian adult mortality. Finally, a number of mortality forecasting methods were retrospectively evaluated for their accuracy in projecting adult death rates for Australia over 10 and 20 years ending in 2012. An appropriate method was applied to create projections for the next three decades. It was found that, compared to the official census-based estimates, more plausible and accurate estimates, especially for ages 95+, could be derived from death counts. The Survivor Ratio (SR) method with results constrained to official estimates for ages 85+ produced accurate very elderly population estimates for Australia across the sexes and ages at both a national and state level. Internal migration is sufficiently minor to be ignored. Very accurate state-level estimates could also be derived using a simpler method of apportioning national single-age estimates between the states. Adult death rates in Australia were found to show consistent and regular patterns of decline since the 1970s, with rates of decline decreasing with age. These patterns support the use of simple direct extrapolation methods for forecasting. The Geometric, Ediev and Lee-Carter BMS methods were all very successful in projecting adult death rates and very elderly populations, and differences between them were small. Australia’s very elderly population increased more than four-fold between 1981 and 2012, from 105,000 to 430,000, or from 0.7% to 1.9% of the total population. Accompanying this growth was an ageing of the very elderly population itself, as well as increasing sex ratios. Improvements in survival beyond age 65 and especially beyond age 85 were the main drivers of growth in nonagenarian and centenarian numbers. Australia’s very elderly population is expected to continue growing rapidly over the next 30 years to almost 1.5 million in 2042, or 4.2% of the total population. Centenarian numbers are expected to increase from almost 3,500 in 2012 to over 15,000. South Australia’s very elderly population is projected to grow the least and Western Australia’s the most. Projected very elderly numbers in 2042 are 13% higher than official projections. Official projections of centenarians were, however, 55% higher. These differences stem from overstated official population estimates and understated death rates for the high ages as well as lower assumed declines in death rates in official projections. This thesis presents more plausible and detailed estimates and projections of Australia’s very elderly population at a state and national level based on methods found to be accurate. It is shown that estimation methods based on deaths can be reliably applied at a sub-national level. The analyses improve our understanding of the demographic drivers of growth of nonagenarians and centenarian populations in Australia, nationally and in the separate states. Insights are gained on how the patterns and trends of change in adult mortality in Australia compare to those internationally. This study furthermore contributes new insights into the accuracy of both old and new mortality forecasting methods. An improved understanding of past trends based on accurate population estimates and death rates, combined with more accurate projections based on accurate data and appropriate methods, facilitates effective planning and budgeting for infrastructure, services, aged pension, aged care and health care for the very elderly.

Objectives The aim of the present study was to assess the extent to which publicly available legislation, policy and guidelines related to breastfeeding and the Baby Friendly Health Initiative (BFHI) underpin and support the uptake and implementation of the BFHI in Australia. Methods Altheide's document analysis model (sample, data collection, data organisation, data analysis and report) was used to source and analyse publicly available legislation, policies and guidelines in Australia that were related to breastfeeding and the BFHI at national, state and professional organisational levels. Results Legislation documents contained no direct references to the BFHI or Code of Marketing of Breast-milk Substitutes, despite the documents being supportive of breastfeeding. There is little reference to the Code of Marketing of Breast-milk Substitutes or to monitoring of the Marketing in Australia of Infant Formulae (MAIF) Agreement at national and state levels. A gap exists in documents that provide up-to-date records regarding monitoring of breastfeeding rates at the national level. Conclusions National and state guidelines are supportive of breastfeeding and the BFHI. However, the BFHI and Code of Marketing of Breast-milk Substitutes are not legislated in Australia and information related to breastfeeding rates is not up to date. A legislative establishment supporting the Code and establishing plans to monitor the MAIF Agreement and breastfeeding outcomes may influence uptake and implementation of the BFHI. What is known about the topic? Extensive evidence supports the health and economic benefits of breastfeeding. Despite a high initiation rate of breastfeeding in Australia (96%) most recently reported in 2010, the rate of breastfed infants dropped considerably over time: approximately 15% of infants were breastfed for the recommended 6 months. Research supports the positive effect of the BFHI on increasing breastfeeding rates and improving breastfeeding outcomes. In 2016, there are 69 Baby-friendly-accredited maternity facilities across Australia, compared with 77 accredited facilities in 2011 (~23% of all maternity facilities). What does this paper add? This is the first document analysis of publicly available legislation, policy and guidelines related to breastfeeding and the BFHI at Australian national, state and professional organisational levels to assess the extent to which these documents support breastfeeding, as well as the uptake and implementation of the BFHI. This study identifies strengths and weaknesses at legislative, policy and guideline levels that could potentially influence the uptake and implementation of the BFHI. What are the implications for practitioners? The uptake and implementation of the BFHI is potentially influenced by legislation, policy and guidelines at national and state levels. Given the low uptake of the BFHI in Australia, this analysis outlines the extent to which these documents support breastfeeding and the BFHI, and indicates what these documents lack with regard to supporting the uptake and implementation of the BFHI.

Summary 1. A large proportion of the world's land surface is extensively managed for livestock production. In areas where livestock systems are becoming more intensive, a major challenge is to predict those plant species likely to decline, persist or increase as a result of agricultural intensification. 2. Most analyses develop inferences for frequent or abundant species, or rely on intensive studies of single species. A promising approach is to identify plant traits related to disturbance to enable inference to be made about changes in plant community composition. We used a Bayesian hierarchical model to analyse the response to agricultural intensification of 494 plant species of pastures and woodlands in southern Australia, and to identify how simple species' traits (life form, growth form and species origin) influence those responses. 3. The probability of occurrence of most species declined along the two intensification gradients, grazing intensity and soil phosphorous concentration, although the occurrence of a greater proportion of species was negatively correlated with soil phosphorous. Responses could be broadly predicted from both plant origin and plant traits, in particular growth form. 4. Native perennial geophytes, ferns and shrubs were most negatively affected by both gradients, while exotic annual grasses and forbs were more tolerant. Along the phosphorous gradient, 24 of the 30 most negatively affected plant species were native geophytes. Mean within-group responses masked considerable within- and between-species variation, particularly for the exotic species group which included species that responded both negatively and positively to intensification. 5. Synthesis and applications. The hierarchical model described here provides a powerful method for estimating individual plant responses and identifying how species' traits influence those responses. Plant species native to southern Australia are sensitive to grazing and phosphorous apparently due to a shared evolutionary history of low grazing intensity and low phosphorous soils. Invading exotic plants have faced strongly contrasting ecological filters, leading to a greater diversity of responses. Where grazing systems have been most intense, a small suite of exotics dominate. Maintaining native and functional plant diversity will necessitate limits being placed on intensive livestock management systems.

BackgroundEvent-based surveillance (EBS) is an essential component of Early Warning Alert and Response (EWAR) as per the International Health Regulations (IHR), 2005. EBS was established in Sudan in 2016 as a complementary system for Indicator-based surveillance (IBS). This review will provide an overview of the current EBS structure, functions and performance in Sudan and identify the gaps and ways forward. MethodsThe review followed the WHO/EMRO guidelines and tools. Structured discussions, observation and review of records and guidelines were done at national and state levels. Community volunteers were interviewed through phone calls. Directors of Health Emergency and Epidemic Control, surveillance officers and focal persons for EBS at the state level were also interviewed. SPSS software was used to perform descriptive statistical analysis for quantitative data, while qualitative data was analysed manually using thematic analysis, paying particular attention to the health system level allowing for an exploration of how and why experiences differ across levels. Written and verbal consents were obtained from all participants as appropriate.ResultsSudan has a functioning EBS; however, there is an underestimation of its contribution and importance at the national and states levels. The link between the national level and states is ad hoc or is driven by the need for reports. While community event-based surveillance (CEBS) is functioning, EBS from health facilities and from non-health sectors is not currently active. The integration of EBS into overall surveillance was not addressed, and the pathway from detection to action is not clear. The use of electronic databases and platforms is generally limited. Factors that would improve performance include training, presence of a trained focal person at state level, and regular follow-up from the national level. Factors such as staff turnover, income in relation to expenses and not having a high academic qualification (Diploma or MSc) were noticed as inhibiting factors.ConclusionThe review recommended revisiting the surveillance structure at national and state levels to put EBS as an essential component and to update guidelines and standard operation procedures SOPs to foster the integration between EBS components and the overall surveillance system. The need for strengthening the link with states, capacity building and re-addressing the training modalities was highlighted.

Back to table of contents Previous article Next article From the SpeakerFull AccessAPA Needs More Input From District BranchesMichael Blumenfield, M.D.Michael BlumenfieldSearch for more papers by this author, M.D.Published Online:4 May 2007https://doi.org/10.1176/pn.42.9.0009At the conclusion of the annual meeting in May, I will complete my term as speaker of the Assembly. I have had the opportunity to visit all the Area meetings, most of them at least three times, over the past three years and have sat on the Board of Trustees and the Finance Committee. I have come to appreciate more than ever the vibrancy of APA, mainly through the dedicated members who spend a great deal of time throughout the year serving APA in various capacities and the great staff under the direction of our medical director.We have so many outstanding psychiatrists who, in addition to treating their patients and working for their local mental health institutions, have chosen to collaborate on the national and local levels to serve our patients and our profession. Nowhere is that more clearly demonstrated than in the Assembly, where we come together representing every district branch plus MITs, ECPs, minority groups, and allied organizations. Not only are creative solutions offered here, but also there is passion in an open, democratic process. The Assembly representatives are an essential connection between local psychiatrists throughout the United States and Canada and the national efforts that originate at APA headquarters.Based on my observations as an Assembly officer, I have concluded that the district branches can take on an even more important role in providing input to our APA and influencing the delivery and quality of mental health services. Most health care decisions that occur on a national level have implications on the state and local level. Similarly, observations, experiences, and data from district branches have significance for APA and the mental health movement in this country.As the result of a joint meeting arranged by APA's president, Dr. Pedro Ruiz, between the APA Board of Trustees and the Board of Trustees of the National Alliance on Mental Illness (NAMI), I set up a program in which a district branch member will serve as a liaison with a local NAMI member. I suggested that there be discussion about the same agenda on which the two boards were dialoguing on the national level. This included the adequacy of mental health care for returning veterans, parity on both the national and state levels, problems with access to care, and other subjects. I also encouraged district branches to hold town-hall meetings to discuss these and other important mental health topics. I suggested that they invite the public and professionals in the community to “testify” before a panel of psychiatrists from the district branch. I believe that this is a method by which we can gain valuable information and data. We can demonstrate to our government leaders and the media that American psychiatry at all levels is involved and active. Several district branches are already planning to undertake this project.This type of action can produce government response and public support as well as action papers in our Assembly. I would hope that someday this would be a hallmark of how APA functions.We expect to see many important actions papers debated in our Assembly later this month in San Diego, with topics including increased access to treating veterans with PTSD, protection of children who testify in criminal procedures, information systems and technology in psychiatry, and the reoccurring question of the relationship between the Assembly and Board of Trustees. We have invited the president of Mental Health America, one of our coalition partners, to speak to us. We also will hear from the president of the Britain's Royal College of Psychiatrists about the pros and cons of the British system of mental health coverage. The discussion and debate on all subjects will be lively, passionate, heartfelt, and always in the best interest of our patients.I want to thank all of the Assembly members for their support and the collegial atmosphere that they always provide. I also appreciate the work of Drs. Jeff Akaka and Ron Burd, my co-officers in the Assembly; Dr. Michael Pearce, my parliamentarian; and of course Lori Klinedinst, Margaret Dewar, Ardell Lockerman, and the other APA staff who work behind the scenes to make our Assembly and all of APA function as well as they do.I know that the Assembly and APA will continue to be responsive to changing events, but we will always be a shining light in the support for mental health care. ▪ ISSUES NewArchived

Medicinal and aromatic plants are offered in a wide variety of products on the market. At least every fourth flowering plant is used. The enormous demand in botanicals results in a huge trade from local to international level. In the 1990s, the reported annual world-wide importation of pharmaceutical plants amounted on average to 400,000 t valued at USD 1,224 million. The international trade is dominated by only few countries. About 80 % of the world-wide imports and exports are allotted to only 12 countries with the dominance of temperate Asian and European countries. Whereas Japan and the Republic of Korea are the main consumers of pharmaceutical plants, and China and India are the world’s leading producing nations, Hong Kong, the USA and Germany stand out as important trade centres. Until now, the production of botanicals relies to a large degree on wildcollection. However, utilization and commerce of wild plant resources are not detrimental in themselves, but, for example, the increasing commercial collection, largely unmonitored trade, and habitat loss lead to an incomparably growing pressure on plant populations in the wild. World-wide an estimated 9,000 medicinal plant species are threatened. Conservation concepts and measures which have to meet future supply and the provisions of species conservation range from resource management, cultivation, shifting processing from consumer to source countries, species conservation to trade restrictions or even trade bans. Medicinal and aromatic plants are of high priority for conservation action, as wild-crafting will certainly continue to play a significant role in their future trade: the sustainable commercial use of their biological resources may provide a financial instrument for nature conservation. INTRODUCTION Phytopharmaceuticals, also some pharmaceuticals, herbal remedies, dietary supplements, homeopathics, medicinal and herbal teas, liqueurs, spirits, sweets, aromas and essences, perfumes, cosmetics, colouring agents, varnishes, fireworks, and detergents – plant-based products offered in a wide variety on the market. Whereas in some goods the herbal ingredients are evident, e.g. in teas or in herbal remedies where they are declared on the packaging, in other products the botanically source is more secret: the bitter taste of Campari is based on the Common Centaury (Centaurium erythraea), and the fenugreek (Trigonella foenum-graecum) contains steroid-saponins which are extracted for use in oral contraceptives. The use of botanical raw material is in many cases much cheaper than to use chemical alternative substances. As a consequence, there is an enormous demand in botanicals resulting in a huge trade, on local, regional, national and international level for domestic use and for commercial trade. Different aspects are associated with the trade in medicinal and aromatic plant material, the trade structure, trade volumes and values, the herbs used and their production, the ecological and socio-economic impacts of the trade, and the management of the botanical resources. Proc. XXVI IHC – Future for Medicinal and Aromatic Plants Eds. L.E. Craker et al. Acta Hort. 629, ISHS 2004 Publication supported by Can. Int. Dev. Agency (CIDA) 178 MEDICINAL AND AROMATIC PLANTS IN USE Species in Use World-wide, it is estimated that up to 70,000 species are used in folk medicine (Farnsworth and Soejarto, 1991). The WHO reports over 21,000 plant taxa used for medicinal purposes (Groombridge, 1992). Unfortunately, there is no idea how many species are used in the other areas of use, like cosmetics, spirits or aromas which makes determining exactly the number of all medicinal and aromatic plant species used worldwide impossible. However, it can be stated, that at least every fourth plant is in use, a calculation based upon the estimated total number of 300-350,000 flowering plants. The number of medicinal and aromatic plant species used in some regions are impressive: In India, which is said to have probably the oldest, richest and most diverse cultural traditions in the use of medicinal plants, about 7,500 species are used in ethnomedicines (Shankar and Majumdar, 1997) which is half of the country’s 17,000 Indian native plant species. In China, the total number of medicinal plants used in different parts of the country add up to some 6,000 species according to Xiao (1991) and to over ten thousand according to He and Sheng (1997). Of these, approximately 1,000 plant species are commonly used in Chinese medicine, and about half of these are considered as the main medicinal plants (He and Sheng, 1997). In Africa, over 5,000 plant species are known to be used for medicinal purposes (Iwu, 1993). In Europe with its long tradition in the use of botanicals, about 2,000 medicinal and aromatic plant species are used on a commercial basis (Lange, 1998). In Germany, Lange (1996) identified not less than 1,500 taxa as sources of medicinal and aromatic plant material. In Spain, it is estimated that 800 medicinal and aromatic plant species are used of which 450 species are associated with commercial use (Blanco and Breaux, 1997; Lange, 1998). Geographical Origin of the Species in Use Herbs used in a country can be either indigenous or native to other regions or even continents. The share of both plant groups depends on the country’s cultural preferences, importance of traditional medicines, history, trade relations, and of course of the wealth or poverty of a country. Traditional medicines are playing an important role in many parts of the world. In south and southeast Asia, the Ayurveda, Unani and Siddha medicines are widely distributed and based on not less than 400, 500 respective 1,800 native Indian plant species (Shankar and Majumdar, 1997). The TCM, the traditional medicine of eastern Asia, relies in most cases on indigenous plant species. Traditional healers in many African countries rely on local or at most regional plant material (Marshall, 1998). In Bulgaria, about 750 native plant species, or 20 % of the total flora, are used in folk medicine. Of these, 200300 species are most commonly used (Hardalova, 1997). Further, in Albania, 205 native plant species are used as sources of botanicals (Vaso, 1997; Lange, 1998). In Hungary, some 270 native medicinal and aromatic plant taxa are used, 180-200 of which are officially recognised by the Hungarian Pharmacopoeia (Bernath, 1996). Ozhatay et al. (1997) list a total of 337 native taxa that have been commercially traded in Turkey since at least 1990 (Lange, 2001). From the French pharmacopoeia and lists of medicines Goi et al. (1997; Lange, 1998) noted some 900 taxa, of which almost half are native to Europe. This means, that many countries rely on a major part on their own plant diversity. Many of them cannot afford to import foreign botanicals, finished herbal products or even phytopharmaceuticals and the country’s own “biodiversity” is mainly offered in a crude form or at most as little processed products on the market. On the other side, there are the developed countries which use besides indigenous plant species a lot of non-native species and process them in their well developed pharmaceutical, cosmetic and extract-producing industry. Accordingly, the plant material is offered to the consumers as mainly packed and finished products, and the crude material plays a minor role in the retail trade. This features apply above all to the highly

The increase in youth electronic nicotine delivery system (ENDS) use coincided with JUUL's rapid rise, which prompted investigations and lawsuits aimed at this leading brand. In response, JUUL discontinued sweet flavors in late 2018, followed by mint flavors in November 2019. We assessed ENDS sales and prices at both the state and national level before and after JUUL's removal of mint flavors. Nielsen retail sales data on ENDS products from convenience and food stores in 4-week aggregates were analyzed between January 2019 and January 2020 in Florida and the United States. Standardized units were created. Unit market share and growth rates were calculated for top brands and flavors in the periods before and after JUUL's mint removal. Average prices within brand and product type were calculated. Following JUUL's removal of mint in November 2019, JUUL's market share dropped from over 66% in Florida and the United States to 37.1% (Florida) and 55.1% (United States). In January 2020, the second leading brands were Puff Bar (15.0%) in Florida and Vuse (18.1%) in the United States. Mint market share decreased and share of all other flavor categories increased, particularly menthol and concept. Total ENDS sales increased in Florida but decreased in the United States. Average prices of ENDS devices decreased. While JUUL's actions led to a decline in its sales, Puff Bar emerged and menthol and concept flavors experienced growth. Findings also demonstrate how changes by influential brands differentially affect purchase patterns at the national and state level. These findings support the growing body of evidence that tobacco industry self-regulation, with selective flavor removal by the leading ENDS brand in this case, is insufficient to reduce total ENDS sales, including sales of flavored products which are preferred by youth. Results suggest that brand and flavor substitution compensated for the removal of mint JUUL pods. Understanding changes to the ENDS market in response to industry actions, at both the state and national level, can inform future regulation and interventions. These findings can also inform efforts to prevent and reduce youth ENDS use.

Drug overdose deaths in the US are currently the highest ever recorded; data collected from public health surveillance sources can help to identify emerging drug use patterns associated with overdose mortality rates, but the time lag in results often limits utility. Urine drug testing (UDT) is one potentially underused source that could augment surveillance efforts through timely data collection. To evaluate the correlation between real-time UDT results from a proprietary national database and overdose mortality data from the National Vital Statistics System. This retrospective cross-sectional study included 500 000 urine specimens submitted for UDT by substance use disorder (SUD) treatment health care practices and collected between January 1, 2013, and December 31, 2020. Real-time UDT data were obtained from the Millennium Health proprietary national database, and overdose mortality data were obtained from the National Vital Statistics System of the Centers for Disease Control and Prevention (CDC WONDER). Specimens were analyzed for specific drugs in 5 categories (cocaine, heroin, methamphetamine, synthetic opioids, and other opioids) using liquid chromatography-tandem mass spectrometry. Participants were adults aged 18 years and older who provided urine specimens at SUD treatment practices. Urine drug testing. The primary outcome was the correlation between UDT positivity rates and overdose mortality rates at national, state, and county levels. Univariate and multivariate regression models were also used to evaluate the association between state- and county-level overdose mortality and standardized UDT positivity rates. Among 500 000 unique patient specimens collected from SUD treatment practices between 2013 and 2020, 288 534 specimens (57.7%) were from men, and the median age of the study population was 34 years (IQR, 17-51 years). On a national level, synthetic opioids and methamphetamine were highly correlated with overdose mortality (Spearman ρ = 0.96 for both). When synthetic opioids were coinvolved, methamphetamine (ρ = 0.98), heroin (ρ = 0.78), cocaine (ρ = 0.94), and other opioids (ρ = 0.83) were also highly correlated with overdose mortality. In the absence of synthetic opioids, all drug categories were highly correlated (ρ = 0.75 for other opioids, 0.81 for heroin, and 0.88 for methamphetamine), with the exception of cocaine (ρ = -0.37). Synthetic opioids (ρ = 0.77) and methamphetamine (ρ = 0.80) had the strongest state-level correlations over time, whereas other opioids had the lowest correlation for both total positivity (ρ = 0.31) and positivity in the absence of synthetic opioids (ρ = 0.23). In Ohio, county-level correlation was strongest for synthetic opioids (ρ = 0.71), followed by heroin (ρ = 0.69) and methamphetamine (ρ = 0.67). At the state level, the multivariate incidence rate ratio (IRR) for synthetic opioids was 1.16 (95% CI, 1.14-1.19; P < .001), and at the county level, the IRR was 1.13 (95% CI, 1.09-1.17; P < .001), suggesting that for every 1-SD increase in the UDT positivity rate, there were 16.2% and 12.8% increases, respectively, in monthly overdose deaths. Both methamphetamine (11.7% increase per 1-SD increase in UDT positivity rate; IRR, 1.12; 95% CI, 1.09-1.14; P < .001) and cocaine (5.1% increase per 1-SD increase in UDT positivity rate; IRR, 1.05; 95% CI, 1.03-1.07; P < .001) also had significant positive associations with mortality rates, but the effect sizes were smaller than that of synthetic opioids (IRR, 1.16). In this study, UDT results were highly correlated with mortality rates at national, state, and county levels. These findings suggest that real-time UDT surveillance can help to quickly identify changes in drug use patterns that might inform targeted harm reduction strategies designed to prevent overdose deaths.

We reviewed and summarized the efforts in the United States to collect data on oral diseases, conditions, and behaviors implemented at the national and state level. The main characteristics of these efforts were: (1) systematic collection of data from representative samples, mostly at the national level; (2) one-time or sporadic experiences when data are collected at state and local levels; (3) use of visual-tactile protocols implemented at the tooth-surface or tooth-site level for data collection; (4) focus mainly on dental caries and periodontal diseases; and (5) leap-time from data collection to publication of results. Using the definition of surveillance in public health (the ongoing and systematic collection, analysis, and interpretation of outcome-specific data for use in planning, implementing, and evaluating public health practice), we show there is an impending need to develop new techniques to build up surveillance systems for oral diseases, conditions, and behaviors at the national, state, and local levels. In the second part of this review, we presented a number of alternative techniques developed in the last 10 years to collect timely data for oral health. The main characteristics of these efforts include: (1) focusing on data collection at state and local level; (2) integration into existing and ongoing surveillance systems; (3) using visual-only protocols to collect data on oral disease status; (4) focusing on a variety of diseases, conditions, and behaviors; and (5) analyzing the data in a timely matter. Many of these efforts have been integrated into the National Oral Health Surveillance System, which has developed eight indicators in response to national health objectives. Finally, we envision the future of visual-tactile protocols in data collection of representative samples to monitor oral health status at the national level and as a research tool. At the state and local level, however, we envision an integrated system of data collection as a constantly evolving process as new techniques are developed in response to new demands.

The Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (CDC/ATSDR) Social Vulnerability Index (SVI) is used to guide policy making and resource allocation for emergency responses. However, limited research has explored the extent to which each variable contributes to the overall calculation of the SVI. We used a factor analysis approach to determine whether specific drivers of vulnerability exist at the state and national levels. We used the 2020 CDC/ATSDR SVI dataset to perform factor analysis separately for each state and nationally. We determined factor weights and scores and conducted a comparative analysis with CDC/ATSDR SVI. The final SVI for each census tract ranged from 0 to 1, with higher values indicating greater vulnerability. At the national level, our factor analysis approach identified 4 primary variables that affected vulnerability the most: the percentage of the population below 150% of the federal poverty level (weight, 0.262), with housing cost burden (ie, households that spend >30% of their income on housing-related costs; weight, 0.226), in a racial and ethnic minority group (weight, 0.232), and without a high school diploma (weight, 0.138). However, at the state level, some analyses assigned low weights to the primary national-level drivers. Our study highlights the need to consider context-specific vulnerability measures when characterizing community social vulnerability. The factor analysis SVI provides nuanced insight into vulnerability drivers at the national and state levels, laying the groundwork for more precise disaster response planning, resource allocation, and community resilience initiatives.

A tourist friendly destination is a concept that gives satisfaction to tourists through contact and the maximum utilization dimensions of space, activities, and products; without any interruptions or problems. Accordingly, this study aims to describe the tourism policy and strategies in national and state contexts, to determine the inherent direction and prospects or potential in the tourism development of Kuala Lumpur as a tourist-friendly destination. The results show that some aspects need to be emphasized and have similarities in each of policies and strategies at the national and state level. This shows that policies made at national level could be followed at state level, so that each line of tourism development planning should be as planned. However, there is currently no planning policy at a national level, only at a state level. This shows that the policy at state level will continue with added value, made from reforms in accordance with the current situation and the existing physical characteristics, not run away with the principle of a planned policy at national level. Accordingly, in Kuala Lumpur, no problems or obstacles exist to planned, managed and developed, through the concept of being a Tourist Friendly City, where it is in line with the requirements of tourism development policies and strategies of national and state levels.

Summary Restoration of native plant communities on previously disturbed land requires the identification and modification of environmental factors that impede or restrict ecosystem succession or development. One of the key factors in successful reclamation is to ensure colonization and persistence of native species within an area. Therefore, the identification of microsite types that favour colonization by native species should improve our ability to successfully reclaim degraded areas. The objectives of this study were to (i) identify and describe microsite types that were conducive to the establishment of five native plant species (Euphrasia frigida, Galium normanii, Thymus praecox, Cerastium spp. and Rumex acetosa) on degraded and reclaimed sites in Iceland; and (ii) to determine the effects of reclamation activities that included the application of manure and inorganic fertilizer on the distribution of microsite types and seedling establishment. Reclamation sites of different ages were examined on an eroded area where the target community was a grass or shrub heath. The spatial distribution of plant establishment was not random but varied among microsite types and study sites. More seedlings than expected were found in microsite types characterized by small rocks and biological soil crusts. These may have entrapped seed and provided more soil stability and moisture than other microsite types. The cover of these microsite types varied among the study sites but the pattern of seedling establishment among the five native forbs was similar. Synthesis and applications. Practical reclamation methods are improved by identifying those factors that promote successful seedling establishment by native species. Application of fertilizer without additional seeding proved to be a simple reclamation approach that increased the availability of one favourable microsite type, enhanced the establishment of native species and subsequently allowed vegetation cover to expand. Seed of native plants may be difficult to obtain commercially, but this approach can be used on degraded land where propagules are available but recovery is slowed by soil instability or nutrient limitations.
