Integrating remote sensing, geographic information system and modeling for estimating crop yield

NASA Astrophysics Data System (ADS)

Salazar, Luis Alonso

This thesis explores various aspects of the use of remote sensing, geographic information system and digital signal processing technologies for broad-scale estimation of crop yield in Kansas. Recent dry and drought years in the Great Plains have emphasized the need for new sources of timely, objective and quantitative information on crop conditions. Crop growth monitoring and yield estimation can provide important information for government agencies, commodity traders and producers in planning harvest, storage, transportation and marketing activities. The sooner this information is available the lower the economic risk translating into greater efficiency and increased return on investments. Weather data is normally used when crop yield is forecasted. Such information, to provide adequate detail for effective predictions, is typically feasible only on small research sites due to expensive and time-consuming collections. In order for crop assessment systems to be economical, more efficient methods for data collection and analysis are necessary. The purpose of this research is to use satellite data which provides 50 times more spatial information about the environment than the weather station network in a short amount of time at a relatively low cost. Specifically, we are going to use Advanced Very High Resolution Radiometer (AVHRR) based vegetation health (VH) indices as proxies for characterization of weather conditions.

High-throughput technology allows for genome-wide measurements at different molecular levels for the same patient, e.g. single nucleotide polymorphisms (SNPs) and gene expression. Correspondingly, it might be beneficial to also integrate complementary information from different molecular levels when building multivariable risk prediction models for a clinical endpoint, such as treatment response or survival. Unfortunately, such a high-dimensional modeling task will often be complicated by a limited overlap of molecular measurements at different levels between patients, i.e. measurements from all molecular levels are available only for a smaller proportion of patients. We propose a sequential strategy for building clinical risk prediction models that integrate genome-wide measurements from two molecular levels in a complementary way. To deal with partial overlap, we develop an imputation approach that allows us to use all available data. This approach is investigated in two acute myeloid leukemia applications combining gene expression with either SNP or DNA methylation data. After obtaining a sparse risk prediction signature e.g. from SNP data, an automatically selected set of prognostic SNPs, by componentwise likelihood-based boosting, imputation is performed for the corresponding linear predictor by a linking model that incorporates e.g. gene expression measurements. The imputed linear predictor is then used for adjustment when building a prognostic signature from the gene expression data. For evaluation, we consider stability, as quantified by inclusion frequencies across resampling data sets. Despite an extremely small overlap in the application example with gene expression and SNPs, several genes are seen to be more stably identified when taking the (imputed) linear predictor from the SNP data into account. In the application with gene expression and DNA methylation, prediction performance with respect to survival also indicates that the proposed approach might

The widespread use of complementary and alternative medicine techniques, often explored by patients without discussion with their primary care physician, is seen as a request from patients for care as well as cure. In this article, we discuss the reasons for the growth of and interest in complementary and alternative medicine in an era of rapidly advancing medical technology. There is, for instance, evidence of the efficacy of supportive techniques such as group psychotherapy in improving adjustment and increasing survival time of cancer patients. We describe current and developing complementary medicine programs as well as opportunities for integration of some complementary techniques into standard medical care. PMID:9584661

Complementary feeding plays a crucial role in the development of infants and toddlers and studies suggest benefits specific to the introduction of food textures. Evaluate the recommendations given to parents, their practices, and their attitudes towards the introduction of food textures during complementary feeding in France. This was a cross-sectional pilot study conducted in 2013. One hundred and eighty-one parents with at least one child aged 6-36 months living in France completed an ad hoc questionnaire. Eighty-eight percent of the parents surveyed received oral information on complementary feeding, but only 46% received such information on the introduction of food textures. Pediatricians were the most frequently listed source of oral information on complementary feeding. More than half the parents also looked for additional information in books and on the internet. While oral recommendations matched parents' practices, they seemed to occur at a later age compared to infants' physiological ability to handle new textures. The quality of information on food texture advice available in paper and electronic formats evaluated using a 4-point scale was found to be limited. Introducing new food texture was spontaneously reported as the most common difficulty in complementary feeding (16%). Fear of choking when first introducing food pieces was reported by 54% of the parents. The parents' lack of information on the introduction of food textures, as well as their fear that their child may choke, should encourage providing new recommendations in France.

The growing evidence on the benefits and risks of complementary and alternative medicine (CAM) and its high rate of use (69% of Australians) - particularly for chronic or recurrent conditions - means increasing attention on CAM. However, few people disclose CAM use to their GP, and health professionals tend to inadequately discuss CAM-related issues with their patients, partly due to insufficient knowledge. As clinical and non-clinical chronic condition management guidelines are a means to educate primary health care practitioners, we undertook a content analysis of guidelines relevant to two common chronic conditions - cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM) - to assess their provision of CAM-related information. Ten current Australian guidelines were reviewed, revealing scant CAM content. When available, the CAM-relevant information was brief, in some cases unclear, inconclusive and lacking in direction to the GP or health care provider. Although we focus on CVD and T2DM, we argue the value of all chronic condition management guidelines integrating relevant evidence-informed information and advice on CAM risks, benefits and referrals, to increase GP awareness and knowledge of appropriate CAM therapies, and potentially to facilitate doctor-client discussion about CAM.

Developers of health information websites aimed at consumers need methods to assess whether their website is of "high quality." Due to the nature of complementary medicine, website information is diverse and may be of poor quality. Various methods have been used to assess the quality of websites, the two main approaches being (1) to compare the content against some gold standard, and (2) to rate various aspects of the site using an assessment tool. We aimed to review available evaluation instruments to assess their performance when used by a researcher to evaluate websites containing information on complementary medicine and breast cancer. In particular, we wanted to see if instruments used the same criteria, agreed on the ranking of websites, were easy to use by a researcher, and if use of a single tool was sufficient to assess website quality. Bibliographic databases, search engines, and citation searches were used to identify evaluation instruments. Instruments were included that enabled users with no subject knowledge to make an objective assessment of a website containing health information. The elements of each instrument were compared to nine main criteria defined by a previous study. Google was used to search for complementary medicine and breast cancer sites. The first six results and a purposive six from different origins (charities, sponsored, commercial) were chosen. Each website was assessed using each tool, and the percentage of criteria successfully met was recorded. The ranking of the websites by each tool was compared. The use of the instruments by others was estimated by citation analysis and Google searching. A total of 39 instruments were identified, 12 of which met the inclusion criteria; the instruments contained between 4 and 43 questions. When applied to 12 websites, there was agreement of the rank order of the sites with 10 of the instruments. Instruments varied in the range of criteria they assessed and in their ease of use.

To establish and optimize the preparation procedures of the anti-complementary polysaccharides from Houttuynia cordata. Based on the yield and anti-complementary activity in vitro, the conditions of extraction and alcohol precipitating process were optimized by orthogonal tests. The optimal condition of deproteinization was determined according to the results of protein removed and polysaccharide maintained. The best decoloring method was also optimized by orthogonal experimental design. The optimized preparation procedures were given as follows: extract the coarse powder 3 times with 50 times volume of water at 90 degrees C for 2 hours every time, combine the extracts and concentrate appropriately, equivalent to 0.12 g of H. cordata per milliliter. Add 4 times volume of 90% ethanol to the extract, allow to stand for 24 hours to precipitate totally, filter and the precipitate was successfully washed with anhydrous alcohol, acetone and anhydrous ether. Resolve the residue with water, add trichloroacetic acid (TCA) to a concentration of 20% to remove protein. Decoloration was at a concentration of 3% with activated carbon at pH 3.0, 50 degrees C for 50 min. The above procedures above were tested 3 times, resulting in the average yield of polysaccharides at 4.03% (RSD 0.96%), the average concentrations of polysaccharides and protein at 80.97% (RSD 1.5%) and 2.02% (RSD 2.3%), and average CH50 at 0.079 g x L-(-1) (RSD 3.6%). The established and optimized procedures are repeatable and reliable to prepare the anti-complementary polysaccharides with high quality and activity from H. cordata.

The Shannon information entropy theory is used to explain the recently proposed isobaric yield ratio difference (IBD) probe which aims to determine the nuclear symmetry energy. Theoretically, the difference between the Shannon uncertainties carried by isobars in two different reactions (ΔIn21), is found to be equivalent to the difference between the chemical potentials of protons and neutrons of the reactions [the IBD probe, IB- Δ(βμ)21, with β the reverse temperature]. From the viewpoints of Shannon information entropy, the physical meaning of the above chemical potential difference is interpreted by ΔIn21 as denoting the nuclear symmetry energy or density difference between neutrons and protons in reactions more concisely than from the statistical ablation-abrasion model.

Introduction and aim The popularity of complementary and alternative medicine (CAM) in treating functional gastrointestinal disorders (FGIDs) has steadily increased in Western countries. We aimed at analyzing available data on CAM effectiveness in functional dyspepsia (FD) patients. Methods A bibliographical search was performed in PubMed using the following keywords: “complementary/alternative medicine,” “hypnosis,” “acupuncture” and/or “functional dyspepsia.” Results In community settings, almost 50% of patients with FGIDs used CAM therapies. Herbal remedies consist of multi-component preparations, whose mechanisms of action have not been systematically clarified. Few studies analyzed the effectiveness of acupuncture in Western countries, yielding conflicting results and possibly reflecting a population bias of this treatment. Hypnosis has been extensively used in irritable bowel syndrome, but few data support its role in treating FD. Conclusions Although some supporting well-designed studies have been recently performed, additional randomized, controlled trials are needed before stating any recommendation on CAM effectiveness in treating FD.

Complementary and alternative medicine is becoming an established intervention modality within the contemporary health care system. Various forms of complementary and alternative medicine are used by patients and practitioners alike, including chiropractic, massage, botanical medicine, homeopathy, and energy therapies. The National Center for Complementary and Alternative Medicine was established within the National Institutes of Health to facilitate evaluation of these alternative therapies, establish an information clearinghouse, and promote research in the field. This article discusses several aspects of complementary and alternative medicine, relates them to women's health, and describes the need for a research agenda to evaluate the impact of the complementary and alternative medicine modalities used for important conditions affecting women.

To review the literature involving complementary and alternative medicine (CAM) for pediatric otitis media. Multiple modalities are discussed, including prevention involving breastfeeding, nutrition, and vaccination; symptomatic treatment involving homeopathy, natural health products, and probiotics; manual manipulations involving osteopathy and chiropractics; and traditional Chinese and Japanese medicine. The information presented will assist physicians in advising patients on their decision-making during the early stages of otitis media when antibiotics and surgery are not yet indicated. A systematic literature search was conducted through January 2012 in PubMed using MESH term "otitis media" in conjunction with "complementary therapies," "homeopathy," "manipulation, osteopathic," "manipulation, chiropractic," "acupuncture therapy," "probiotics," "naturopathy," and "xylitol." Theses searches yielded 163 unique results. Abstracts and titles were evaluated for relevance. Case reports, case series, randomized controlled trials, and basic science research were included. Publications not relevant to the discussion of alternative medicine in otitis media were excluded. Bibliographies were checked for further publications. Thirty-six unique publications were reviewed. Of all therapies in complementary and alternative medicine, only xylitol has been studied in well-designed, randomized, blinded trials; it is likely effective, but compliance limits its applicability. Management of acute otitis media begins with watchful waiting. Herbal eardrops may help relieve symptoms. Homeopathic treatments may help decrease pain and lead to faster resolution. Prevention should be emphasized with elimination of risk factors, such as second hand smoke and bottle-feeding, as well as maintaining nutrition and vaccinations. Vitamin supplementation may be helpful. Probiotics and xylitol may be beneficial as well. Traditional Chinese/Japanese therapies show promising results but remain

This project aims to assess the utility of bibliographic databases beyond the three major ones (MEDLINE, EMBASE and Cochrane CENTRAL) for finding controlled trials of complementary and alternative medicine (CAM). Fifteen databases were searched to identify controlled clinical trials (CCTs) of CAM not also indexed in MEDLINE. Searches were conducted in May 2006 using the revised Cochrane highly sensitive search strategy (HSSS) and the PubMed CAM Subset. Yield of CAM trials per 100 records was determined, and databases were compared over a standardized period (2005). The Acudoc2 RCT, Acubriefs, Index to Chiropractic Literature (ICL) and Hom-Inform databases had the highest concentrations of non-MEDLINE records, with more than 100 non-MEDLINE records per 500. Other productive databases had ratios between 500 and 1500 records to 100 non-MEDLINE records—these were AMED, MANTIS, PsycINFO, CINAHL, Global Health and Alt HealthWatch. Five databases were found to be unproductive: AGRICOLA, CAIRSS, Datadiwan, Herb Research Foundation and IBIDS. Acudoc2 RCT yielded 100 CAM trials in the most recent 100 records screened. Acubriefs, AMED, Hom-Inform, MANTIS, PsycINFO and CINAHL had more than 25 CAM trials per 100 records screened. Global Health, ICL and Alt HealthWatch were below 25 in yield. There were 255 non-MEDLINE trials from eight databases in 2005, with only 10% indexed in more than one database. Yield varied greatly between databases; the most productive databases from both sampling methods were Acubriefs, Acudoc2 RCT, AMED and CINAHL. Low overlap between databases indicates comprehensive CAM literature searches will require multiple databases. PMID:19468052

Communication between different health care providers (conventional and complementary) and cancer patients about their use of complementary therapies affects the health and safety of the patients. The aim of this study was to examine the qualitative research literature on the perception of and communication about the risk of complementary therapies between different health care providers and cancer patients. Systematic searches in six medical databases covering literature from 2000 to 2015 were performed. The studies were accessed according to the level of evidence and summarized into different risk situations. Qualitative content analysis was used to analyze the text data, and the codes were defined before and during the data analysis. Twenty-nine papers were included in the primary analysis and five main themes were identified and discussed. The main risk situations identified were 1. Differences in treatment concepts and philosophical values among complementary and conventional health care providers. 2. Adverse effects from complementary products and herbs due to their contamination/toxicity and interactions with conventional cancer treatment. 3. Health care physicians and oncologists find it difficult to recommend many complementary modalities due to the lack of scientific evidence for their effect. 4. Lack of knowledge and information about complementary and conventional cancer treatments among different health care providers. The risk of consuming herbs and products containing high level of toxins is a considerable threat to patient safety (direct risk). At the same time, the lack of scientific evidence of effect for many complementary therapies and differences in treatment philosophy among complementary and conventional health care providers potentially hinder effective communication about these threats with mutual patients (indirect risk). As such, indirect risk may pose an additional risk to patients who want to combine complementary therapies with

This paper describes a robust and simple algorithm for an attitude and heading reference system (AHRS) based on low-cost MEMS inertial and magnetic sensors. The proposed approach relies on a gain-scheduled complementary filter, augmented by an acceleration-based switching architecture to yield robust performance, even when the vehicle is subject to strong accelerations. Experimental results are provided for a road captive test during which the vehicle dynamics are in high-acceleration mode and the performance of the proposed filter is evaluated against the output from a conventional linear complementary filter.

Yang, Thomas; Shen, Yang; Zhang, Yifan; Sweis, Jason; Lai, Ya-Chieh

2017-03-01

Silicon testing results are regularly collected for a particular lot of wafers to study yield loss from test result diagnostics. Product engineers will analyze the diagnostic results and perform a number of physical failure analyses to detect systematic defects which cause yield loss for these sets of wafers in order to feedback the information to process engineers for process improvements. Most of time, the systematic defects that are detected are major issues or just one of the causes for the overall yield loss. This paper will present a working flow for using design analysis techniques combined with diagnostic methods to systematically transform silicon testing information into physical layout information. A new set of the testing results are received from a new lot of wafers for the same product. We can then correlate all the diagnostic results from different periods of time to check which blocks or nets have been highlighted or stop occurring on the failure reports in order to monitor process changes which impact the yield. The design characteristic analysis flow is also implemented to find 1) the block connections on a design that have failed electrical test or 2) frequently used cells that been highlighted multiple times.

To document mineral contents iron, zinc, calcium, energy contents and nutrient densities in complementary foods commonly given to young urban slum children. Information on dietary intake was collected from 892 mothers of children aged 13-24 months, using 24 hour dietary recall and standardized measures. Three variations of 27 most commonly prepared recipes were analyzed and their energy (Kcal/g) and nutrient densities (mg/100 Kcal) were calculated. Considerable variations were observed in preparation of all items fed to the children. Cereal-based items predominated their diets with only small amount of vegetables/fruits. Fenugreek was the only leafy vegetable included, but was given to only 1-2% of children. Iron, calcium, zinc contents of staple complementary foods ranged from: 0.33 mg to 3.73 mg, 4 mg to 64 mg, and 0.35 mg to 2.99 mg/100 respectively. Recipes diluted with less water and containing vegetables, spices had higher mineral content. Minerals densities were higher for dals, fenugreek vegetable, khichdi and chapatti. Using the median amounts of the various recipes fed to children, intakes of all nutrients examined especially calcium and iron was low. There is an urgent need to educate mothers about consistency, dilution, quantity, frequency, method of preparation, inclusion of micronutrient-rich foods, energy-dense complementary foods and gender equality.

The aims of this study were to: (1) determine the types of complementary and alternative medicine use among children with thalassaemia as reported by parents and (2) describe sociodemographic and medical factors associated with the use of such treatments in families residing in southern Turkey. Thalassaemia is one of the most common human genetic diseases. Despite the therapeutic efforts, patients will encounter a variety of physical and psychological problems. Therefore, the use of complementary and alternative medicines among children thalassaemia is becoming increasingly popular. This is a descriptive study of complementary and alternative medicine. This study was conducted in the Hematology Outpatient Clinic at Akdeniz University Hospital and in the Thalassemia Centre at Ministry of Health Antalya Education and Research Hospital, Antalya, Turkey, between January 2010-December 2010. Parents of 97 paediatric patients, among 125 parents who applied to the haematology outpatient clinic and thalassaemia centre between these dates, agreed to take part in the study with whom contact could be made were included. Data were collected by using a questionnaire. The proportion of parents who reported using one or more of the complementary and alternative medicine methods was 82·5%. Of these parents, 61·8% were using prayer/spiritual practice, 47·4% were using nutritional supplements and 35·1% were using animal materials. It was determined that a significant portion of the parents using complementary and alternative medicine use it to treat their children's health problems, they were informed about complementary and alternative medicine by their paediatricians and family elders, and they have discussed the use of complementary and alternative medicine with healthcare professionals. To sustain medical treatment and prognosis of thalassaemia, it is important for nurses to consult with their patients and parents regarding the use and potential risks of some complementary

A Remote Sensing-Derived Corn Yield Assessment Model

NASA Astrophysics Data System (ADS)

Shrestha, Ranjay Man

Agricultural studies and food security have become critical research topics due to continuous growth in human population and simultaneous shrinkage in agricultural land. In spite of modern technological advancements to improve agricultural productivity, more studies on crop yield assessments and food productivities are still necessary to fulfill the constantly increasing food demands. Besides human activities, natural disasters such as flood and drought, along with rapid climate changes, also inflect an adverse effect on food productivities. Understanding the impact of these disasters on crop yield and making early impact estimations could help planning for any national or international food crisis. Similarly, the United States Department of Agriculture (USDA) Risk Management Agency (RMA) insurance management utilizes appropriately estimated crop yield and damage assessment information to sustain farmers' practice through timely and proper compensations. Through County Agricultural Production Survey (CAPS), the USDA National Agricultural Statistical Service (NASS) uses traditional methods of field interviews and farmer-reported survey data to perform annual crop condition monitoring and production estimations at the regional and state levels. As these manual approaches of yield estimations are highly inefficient and produce very limited samples to represent the entire area, NASS requires supplemental spatial data that provides continuous and timely information on crop production and annual yield. Compared to traditional methods, remote sensing data and products offer wider spatial extent, more accurate location information, higher temporal resolution and data distribution, and lower data cost--thus providing a complementary option for estimation of crop yield information. Remote sensing derived vegetation indices such as Normalized Difference Vegetation Index (NDVI) provide measurable statistics of potential crop growth based on the spectral reflectance and could

The American Academy of Pediatrics is dedicated to optimizing the well-being of children and advancing family-centered health care. Related to these goals, the American Academy of Pediatrics recognizes the increasing use of complementary and alternative medicine in children and, as a result, the need to provide information and support for pediatricians. From 2000 to 2002, the American Academy of Pediatrics convened and charged the Task Force on Complementary and Alternative Medicine to address issues related to the use of complementary and alternative medicine in children and to develop resources to educate physicians, patients, and families. One of these resources is this report describing complementary and alternative medicine services, current levels of utilization and financial expenditures, and associated legal and ethical considerations. The subject of complementary and alternative medicine is large and diverse, and consequently, an in-depth discussion of each method of complementary and alternative medicine is beyond the scope of this report. Instead, this report will define terms; describe epidemiology; outline common types of complementary and alternative medicine therapies; review medicolegal, ethical, and research implications; review education and training for complementary and alternative medicine providers; provide resources for learning more about complementary and alternative medicine; and suggest communication strategies to use when discussing complementary and alternative medicine with patients and families.

The aims of this study were to determine the prevalence of complementary and alternative medicine use in patients with arthritis, the types of complementary and alternative medicine used, pertinent socio-demographic factors associated with complementary and alternative medicine use and its perceived efficacy. Arthritis is a major health issue, and the use of complementary and alternative medicine among patients with arthritis is common. This is a descriptive cross-sectional study. Data were obtained from 250 patients with arthritis at the physiotherapy and immunology clinics Atatürk University Hospital in eastern Turkey between May-July 2005 using a questionnaire developed specifically for this study. The instrument included questions on socio-demographic information, disease specifics and complementary and alternative medicine usage. Seventy-six per cent of participants reported use of at least one form of complementary and alternative medicine in the previous year. Complementary and alternative medicine users and non-users were not significantly different in most socio-demographic characteristics including age, gender, marital status and education level with the exception of economic status. We categorised treatment into six complementary and alternative medicine categories: 62.6% of patients used thermal therapies; 41.5% used oral herbal therapies; 40.5% used hot therapies; 32.6% used externally applied (skin) therapies; 28.4% used massage and 12.6% used cold therapies. All forms of complementary and alternative medicine except thermal and oral herbal therapies were perceived as very effective by more than half of study participants. Complementary and alternative medicine therapy is widely used by patients with arthritis and has perceived beneficial effects. It is important for nurses and other health care professionals to be knowledgeable about the use of complementary and alternative medicine therapies when providing care to patients with arthritis because of

To estimate the overall prevalence of complementary and alternative medicine use among children with cystic fibrosis, determine specific modalities used, predictors of use and subjective helpfulness or harm from individual modalities. Of 53 children attending the cystic fibrosis clinic in London, Ontario (100% recruitment), 79% had used complementary and alternative medicine. The most commonly used modalities were air purifiers, humidifiers, probiotics, and omega-3 fatty acids. Family complementary and alternative medicine use was the only independent predictor of overall use. The majority of patients perceived benefit from specific modalities for cystic fibrosis symptoms. Given the high frequency and number of modalities used and lack of patient and disease characteristics predicting use, we recommend that health care providers should routinely ask about complementary and alternative medicine among all pediatric cystic fibrosis patients and assist patients in understanding the potential benefits and risks to make informed decisions about its use.

Complementary Speckle Patterns: Deterministic Interchange of Intrinsic Vortices and Maxima through Scattering Media.

PubMed

Gateau, Jérôme; Rigneault, Hervé; Guillon, Marc

2017-01-27

Intensity maxima and zeros of speckle patterns obtained behind a diffuser are experimentally interchanged by applying a spiral phase delay of charge ±1 to the impinging coherent beam. This transform arises from the expectation that tightly focused beams, which have a planar wave front around the focus, are so changed into vortex beams and vice versa. The statistics of extrema locations and the intensity distribution of the so-generated "complementary" patterns are characterized by numerical simulations. It is demonstrated experimentally that the incoherent superposition of the three "complementary speckle patterns" yield a synthetic speckle grain size enlarged by a factor of sqrt[3]. A cyclic permutation of optical vortices and intensity maxima is unexpectedly observed and discussed.

To describe the use of complementary approaches in pregnant women with a history of miscarriage and to investigate whether a miscarriage is associated with the use of complementary approaches during their pregnancy. A cross-sectional survey was distributed to pregnant women residing in the United States (N=890). Women who had a history of miscarriage, were Caucasian, were college educated, reported a high income, had low depression scores, and had low anxiety scores (all P<0.001) were more likely to use complementary approaches. In pregnant women with a history of miscarriage (N=193), the most frequently reported complementary approaches used were prayer (22.3%), yoga (15%), massage (14.5%), chiropractic (13%), and meditation (11.4%). Finally, after adjustment for age, race, education, and income, the odds of using a complementary approach in women with a history of miscarriage was 1.8 (95% CI: 1.3, 2.5, P<0.001) as compared with women without a history of miscarriage (model 1). Associations persisted after additional adjustment for depression, anxiety, and stress; the odds of using a complementary approach in women with a history of miscarriage was 1.7 (95% CI: 1.2, 2.4, P<0.001) (model 2), compared with women without a history of miscarriage. Findings from this study may help inform future studies for pregnant women with a history of miscarriage and may also provide information about appropriate strategies in which health care providers can refer their patients.

The research examined complementary and alternative medicine (CAM) information-seeking behaviors and preferences from short- to long-term cancer survival, including goals, motivations, and information sources. A mixed-methods approach was used with cancer survivors from the "Assessment of Patients' Experience with Cancer Care" 2004 cohort. Data collection included a mail survey and phone interviews using the critical incident technique (CIT). Seventy survivors from the 2004 study responded to the survey, and eight participated in the CIT interviews. Quantitative results showed that CAM usage did not change significantly between 2004 and 2015. The following themes emerged from the CIT: families' and friends' provision of the initial introduction to a CAM, use of CAM to manage the emotional and psychological impact of cancer, utilization of trained CAM practitioners, and online resources as a prominent source for CAM information. The majority of participants expressed an interest in an online information-sharing portal for CAM. Patients continue to use CAM well into long-term cancer survivorship. Finding trustworthy sources for information on CAM presents many challenges such as reliability of source, conflicting information on efficacy, and unknown interactions with conventional medications. Study participants expressed interest in an online portal to meet these needs through patient testimonials and linkage of claims to the scientific literature. Such a portal could also aid medical librarians and clinicians in locating and evaluating CAM information on behalf of patients.

How yield relates to ash content, Δ13C and Δ18O in maize grown under different water regimes

PubMed Central

Cabrera-Bosquet, Llorenç; Sánchez, Ciro; Araus, José Luis

2009-01-01

Background and Aims Stable isotopes have proved a valuable phenotyping tool when breeding for yield potential and drought adaptation; however, the cost and technical skills involved in isotope analysis limit its large-scale application in breeding programmes. This is particularly so for Δ18O despite the potential relevance of this trait in C4 crops. The accumulation of minerals (measured as ash content) has been proposed as an inexpensive way to evaluate drought adaptation and yield in C3 cereals, but little is known of the usefulness of this measure in C4 cereals such as maize (Zea mays). The present study investigates how yield relates to ash content, Δ13C and Δ18O, and evaluates the use of ash content as an alternative or complementary criterion to stable isotopes in assessing yield potential and drought resistance in maize. Methods A set of tropical maize hybrids developed by CIMMYT were subjected to different water availabilities, in order to induce water stress during the reproductive stages under field conditions. Ash content and Δ13C were determined in leaves and kernels. In addition, Δ18O was measured in kernels. Key Results Water regime significantly affected yield, ash content and stable isotopes. The results revealed a close relationship between ash content in leaves and the traits informing about plant water status. Ash content in kernels appeared to reflect differences in sink–source balance. Genotypic variation in grain yield was mainly explained by the combination of ash content and Δ18O, whilst Δ13C did not explain a significant percentage of such variation. Conclusions Ash content in leaves and kernels proved a useful alternative or complementary criterion to Δ18O in kernels for assessing yield performance in maize grown under drought conditions.

Orientation of public and physicians to the complementary and alternative medicine (CAM) is one of the most prominent symbols of structural changes in the health service system. The aim of his study was a determination of knowledge, attitude, and practice of general practitioners in complementary and alternative medicine. This cross- sectional study was conducted in Qazvin, Iran in 2013. A self-administered questionnaire was used for collecting data including four information parts: population information, physicians' attitude and knowledge, methods of getting information and their function. A total of 228 physicians in Qazvin comprised the population of study according to the deputy of treatment's report of Qazvin University of Medical Sciences. A total of 150 physicians were selected randomly, and SPSS Statistical program was used to enter questionnaires' data. Results were analyzed as descriptive statistics and statistical analysis. Sixty percent of all responders were male. About sixty (59.4) percent of participating practitioners had worked less than 10 years.96.4 percent had a positive attitude towards complementary and alternative medicine. Knowledge of practitioners about traditional medicine in 11 percent was good, 36.3% and 52.7% had average and little information, respectively. 17.9% of practitioners offered their patients complementary and alternative medicine for treatment. Although there was little knowledge among practitioners about traditional medicine and complementary approaches, a significant percentage of them had attitude higher than the lower limit.

Complementary Hand Responses Occur in Both Peri- and Extrapersonal Space.

PubMed

Faber, Tim W; van Elk, Michiel; Jonas, Kai J

2016-01-01

Human beings have a strong tendency to imitate. Evidence from motor priming paradigms suggests that people automatically tend to imitate observed actions such as hand gestures by performing mirror-congruent movements (e.g., lifting one's right finger upon observing a left finger movement; from a mirror perspective). Many observed actions however, do not require mirror-congruent responses but afford complementary (fitting) responses instead (e.g., handing over a cup; shaking hands). Crucially, whereas mirror-congruent responses don't require physical interaction with another person, complementary actions often do. Given that most experiments studying motor priming have used stimuli devoid of contextual information, this space or interaction-dependency of complementary responses has not yet been assessed. To address this issue, we let participants perform a task in which they had to mirror or complement a hand gesture (fist or open hand) performed by an actor depicted either within or outside of reach. In three studies, we observed faster reaction times and less response errors for complementary relative to mirrored hand movements in response to open hand gestures (i.e., 'hand-shaking') irrespective of the perceived interpersonal distance of the actor. This complementary effect could not be accounted for by a low-level spatial cueing effect. These results demonstrate that humans have a strong and automatic tendency to respond by performing complementary actions. In addition, our findings underline the limitations of manipulations of space in modulating effects of motor priming and the perception of affordances.

Responding to GPs' information resource needs: implementation and evaluation of a complementary medicines information resource in Queensland general practice

PubMed Central

2011-01-01

Background Australian General Practitioners (GPs) are in the forefront of primary health care and in an excellent position to communicate with their patients and educate them about Complementary Medicines (CMs) use. However previous studies have demonstrated that GPs lack the knowledge required about CMs to effectively communicate with patients about their CMs use and they perceive a need for information resources on CMs to use in their clinical practice. This study aimed to develop, implement, and evaluate a CMs information resource in Queensland (Qld) general practice. Methods The results of the needs assessment survey of Qld general practitioners (GPs) informed the development of a CMs information resource which was then put through an implementation and evaluation cycle in Qld general practice. The CMs information resource was a set of evidence-based herbal medicine fact sheets. This resource was utilised by 100 Qld GPs in their clinical practice for four weeks and was then evaluated. The evaluation assessed GPs' (1) utilisation of the resource (2) perceived quality, usefulness and satisfaction with the resource and (3) perceived impact of the resource on their knowledge, attitudes, and practice of CMs. Results Ninety two out of the 100 GPs completed the four week evaluation of the fact sheets and returned the post-intervention survey. The herbal medicine fact sheets produced by this study were well accepted and utilised by Qld GPs. The majority of GPs perceived that the fact sheets were a useful resource for their clinical practice. The fact sheets improved GPs' attitudes towards CMs, increased their knowledge of those herbal medicines and improved their communication with their patients about those specific herbs. Eighty-six percent of GPs agreed that if they had adequate resources on CMs, like the herbal medicine fact sheets, then they would communicate more to their patients about their use of CMs. Conclusion Further educational interventions on CMs need to

2009-12-01

The goal of this study was to develop and evaluate a complementary cyber education program for a required pathophysiology class for nursing students. The cyber education program comprised electronic bulletin boards, correspondence material storage, an announcement section, a report submission section, reference sites, and statistics on learning rates. Twelve online lectures complemented five lectures in the classroom. To evaluate the course's educational effectiveness, we performed an online objective questionnaire and an open questionnaire survey anonymously, and compared the complementary cyber education program with traditional classroom education. The complementary cyber education program effected significant improvements in scores for importance with regard to major, clarity of goals and education plans for courses, professor readiness, preciseness and description of lectures, amount and efficiency of assignments, and fairness in appraisal standards compared with the traditional classroom education group. This study indicates that a complementary cyber education program provides nursing students with the flexibility of time and space, the newest information through updated lectures, efficient motivational aids through intimacy between the lecturer and students, and concrete and meaningful tasks. The complementary cyber education course also increased student effort toward studying and student satisfaction with the class.

2016-05-01

This article describes the use of complementary and alternative medicines in an outpatient pediatric neurology clinic, and assesses family attitudes toward the efficacy of complementary and alternative medicines versus prescription medications. Complementary and alternative medicine is an important element of the modern health care landscape. There is limited information about whether, and to what extent, families perceive its utility in childhood neurological disorders. Surveys were distributed to 500 consecutive patients at a child neurology clinic in Rochester, Minnesota. Questions pertained to the child's diagnoses, use of complementary and alternative medicines, and the specific complementary and alternative medicine modalities that were used. Opinions were also gathered on the perceived efficacy of complementary and alternative medicines and prescription medications. Data were compared using χ(2) or Fisher exact tests as indicated. A total of 484 surveys were returned, of which 327 were usable. Only 17.4% admitted to use of complementary and alternative medicine to treat neurological problems. However, in follow-up questioning, actually 41.6% of patients recognized that they were using one or more types of complementary and alternative medicines. Disorders associated with a statistically significant increased prevalence of complementary and alternative medicine use were headache (50.8% with headache used complementary and alternative medicine versus 35.7% without headache; P = 0.008, Fisher exact test), chronic fatigue (63.2% vs 38.8%; P = 0.005, Fisher exact test), and sleep disorders (77.1% vs 37.3%; P < 0.0001, Fisher exact test). A large proportion of pediatric neurology patients in our clinic are also using complementary and alternative medicine. Only 38.5% of these recognize themselves as using complementary and alternative medicine, underlining the need to inquire in-depth about its use. Patients who are less satisfied with their prescription

Complementary medicine for cancer patients in general practice: qualitative interviews with german general practitioners.

Dahlhaus, Anne; Siebenhofer, Andrea; Guethlin, Corina

2015-01-01

The aim of this study was to investigate how general practitioners react when their cancer patients show interest in complementary medicine, and how their reaction is related to their knowledge in the field. We conducted semi-structured interviews with 10 German general practitioners. Interviewees came from 5 different federal states and varied in terms of urban/rural setting, single/joint practice, additional certifications, gender and length of professional experience. Interviews were electronically recorded, transcribed and then analysed using qualitative content analysis according to Mayring. General practitioners feel largely responsible for providing information on complementary medicine to their cancer patients. However, uncertainty and a lack of knowledge concerning CAM lead mainly to reactive responses to patients' needs, and the general practitioners base their recommendations on personal experiences and attitudes. They wish to support their cancer patients and thus, in order to keep their patients' hopes up and maintain a trusting relationship, sometimes support complementary medicine, regardless of their own convictions. Although general practitioners see themselves as an important source of information on complementary medicine for their cancer patients, they also speak of their uncertainties and lack of knowledge. General practitioners would profit from training in complementary medicine enabling them to discuss this topic with their cancer patients in a proactive, open and honest manner. © 2015 S.

To provide a comprehensive review of complementary and alternative medicine (CAM) therapies for the treatment of pulmonary disorders in children. The use of complementary medicine (CAM) is commonly used by both children and adults with breathing problems, and especially in chronic pulmonary disorders such as asthma and cystic fibrosis. Many clinics and hospitals now offer CAM, even though most of the conventionally trained health practitioners have little knowledge or education regarding CAM therapies. Research in CAM that demonstrates overall benefit is lacking, especially in children. Often parents do not report CAM use to their child's healthcare provider and this could compromise their overall quality of care. Although many research studies evaluating CAM therapies have methodological flaws, data exist to support CAM therapies in treating children with pulmonary disorders. This review examines the latest evidence of CAM use and effectiveness in children with pulmonary disorders. Physicians should be aware of the many CAM therapy options and the research surrounding them in order to provide their patients with the most current and accurate information available.

Complementary and Alternative Medicine in Cardiac Surgery: Prevalence and Modality of use.

2016-07-01

Complementary and alternative medicines are developing at a growing rate but their use in the hospital setting is little known, ignoring risk or benefit in practice. The objectives of the study were to quantify the prevalence of complementary and alternative medicines used by patients admitted to a cardiac surgery department. Patients and staff at the Cardiac Surgery unit of Angers University Hospital (France) were surveyed regarding their modality of complementary and alternative medicines use, between April 01, 2013, and April 18, 2014, by means of an anonymous questionnaire. Of 154 patients included in the study, 58% used a complementary and alternative medicine at least once in their lifetime, 38% during the preceding year, and 14% between the consultation and surgery. In all, 71% used them as a complement to their conventional medical treatment. Of those who used a complementary and alternative medicine during the year of their surgery procedure, only 29% informed their physicians and paramedical staff about it. Complementary and alternative medicines use among patients admitted to cardiac surgery units is common. Yet there is a real lack of knowledge regarding these health practices among physicians and paramedical staff.

Influence of management and environment on Australian wheat: information for sustainable intensification and closing yield gaps

NASA Astrophysics Data System (ADS)

Bryan, B. A.; King, D.; Zhao, G.

2014-04-01

In the future, agriculture will need to produce more, from less land, more sustainably. But currently, in many places, actual crop yields are below those attainable. We quantified the ability for agricultural management to increase wheat yields across 179 Mha of potentially arable land in Australia. Using the Agricultural Production Systems Simulator (APSIM), we simulated the impact on wheat yield of 225 fertilization and residue management scenarios at a high spatial, temporal, and agronomic resolution from 1900 to 2010. The influence of management and environmental variables on wheat yield was then assessed using Spearman’s non-parametric correlation test with bootstrapping. While residue management showed little correlation, fertilization strongly increased wheat yield up to around 100 kg N ha-1 yr-1. However, this effect was highly dependent on the key environment variables of rainfall, temperature, and soil water holding capacity. The influence of fertilization on yield was stronger in cooler, wetter climates, and in soils with greater water holding capacity. We conclude that the effectiveness of management intensification to increase wheat yield is highly dependent upon local climate and soil conditions. We provide context-specific information on the yield benefits of fertilization to support adaptive agronomic decision-making and contribute to the closure of yield gaps. We also suggest that future assessments consider the economic and environmental sustainability of management intensification for closing yield gaps.

Sustainable approaches to improving infant and young child feeding are needed. The Nutridev program worked in Vietnam, Madagascar, and Burkina Faso to test different strategies to improve complementary feeding using fortified products sold to families. To review the experiences of programs producing and marketing fortified complementary foods and to report on the feasibility of local production and marketing of fortified complementary foods to increase usage of high-quality foods among children of low-income families in a self-sustaining manner. Project documents, surveys of mothers, and production and sales reports were reviewed. Nutridev experience in Vietnam, Madagascar, and Burkina Faso demonstrates that it is possible to produce affordable, high-quality complementary foods and supplements locally in developing countries. Strategies to make products readily available to the targeted population and to convince this population to consume them yielded mixed results, varying greatly based on the strategy utilized and the context in which it was implemented. In several contexts, the optimal approach appears to be strengthening the existing food distribution network to sell complementary foods and supplements, with the implementation of a temporary promotion and nutrition education network in partnership with local authorities (e.g., health services) to increase awareness among families about the fortified complementary food product and optimal feeding practices. In urban areas, where the density of the population is high, design and implementation of specific networks very close to consumers seems to be a good way to combine economic sustainability and good consumption levels.

Yoga is being used by a growing number of youth and adults as a means of improving overall health and fitness. There is also a progressive trend toward use of yoga as a mind-body complementary and alternative medicine intervention to improve specific physical and mental health conditions. To provide clinicians with therapeutically useful information about yoga, the evidence evaluating yoga as an effective intervention for children and adolescents with health problems is reviewed and summarized. A brief overview of yoga and yoga therapy is presented along with yoga resources and practical strategies for clinical practitioners to use with their patients. The majority of available studies with children and adolescents suggest benefits to using yoga as a therapeutic intervention and show very few adverse effects. These results must be interpreted as preliminary findings because many of the studies have methodological limitations that prevent strong conclusions from being drawn. Yoga appears promising as a complementary therapy for children and adolescents. Further information about how to apply it most effectively and more coordinated research efforts are needed.

From Observation to Information: Data-Driven Understanding of on Farm Yield Variation

Agriculture research uses “recommendation domains” to develop and transfer crop management practices adapted to specific contexts. The scale of recommendation domains is large when compared to individual production sites and often encompasses less environmental variation than farmers manage. Farmers constantly observe crop response to management practices at a field scale. These observations are of little use for other farms if the site and the weather are not described. The value of information obtained from farmers’ experiences and controlled experiments is enhanced when the circumstances under which it was generated are characterized within the conceptual framework of a recommendation domain, this latter defined by Non-Controllable Factors (NCFs). Controllable Factors (CFs) refer to those which farmers manage. Using a combination of expert guidance and a multi-stage analytic process, we evaluated the interplay of CFs and NCFs on plantain productivity in farmers’ fields. Data were obtained from multiple sources, including farmers. Experts identified candidate variables likely to influence yields. The influence of the candidate variables on yields was tested through conditional forests analysis. Factor analysis then clustered harvests produced under similar NCFs, into Homologous Events (HEs). The relationship between NCFs, CFs and productivity in intercropped plantain were analyzed with mixed models. Inclusion of HEs increased the explanatory power of models. Low median yields in monocropping coupled with the occasional high yields within most HEs indicated that most of these farmers were not using practices that exploited the yield potential of those HEs. Varieties grown by farmers were associated with particular HEs. This indicates that farmers do adapt their management to the particular conditions of their HEs. Our observations confirm that the definition of HEs as recommendation domains at a small-scale is valid, and that the effectiveness of distinct

The popularity of complementary and alternative medicine (CAM) has increased tremendously in recent years. Thus, it is imperative to distinguish between alternative therapies that can be dangerous and complementary therapies that are primarily palliative and augment conventional treatment. Memorial Sloan-Kettering Cancer Center's Integrative Medicine Service offers complementary therapies to patients in an attempt to improve quality of life and provide symptom management. In addition to clinical services, it also provides education to health care professionals and the public and performs clinical and laboratory research on complementary modalities and the antitumor properties of botanicals. If CAM is to be accepted by mainstream medicine, research must be done usingstandard research methodologies.

An Evidence-Based Course in Complementary Medicines

Hughes, Jeff

2012-01-01

Objective. To evaluate the impact of an evidence-based course in complementary medicines on the attitudes, knowledge, and professional practice behavior of undergraduate pharmacy students. Design. A required 12-week evidence-based complementary medicine course was designed and introduced into the third-year undergraduate pharmacy curriculum. The course included a combination of traditional lectures, interactive tutorial sessions, and a range of formal assessments. Assessment. Pre- and post-course survey instruments were administered to assess changes in students’ attitudes, perceptions, knowledge, and the likelihood they would recommend the use of complementary medicines in a pharmacy practice environment. Conclusion. Completion of a required evidence-based complementary medicines course resulted in a positive change in pharmacy students’ perceptions of the value of various complementary medicines as well as in their willingness to recommend them, and provided students with the required knowledge to make patient-centered recommendations for use of complementary medicines in a professional pharmacy practice setting. These findings support the need for greater evidence-based complementary medicine education within pharmacy curricula to meet consumer demand and to align with pharmacists’ professional responsibilities.

The aims of this study were to determine (1) the prevalence of complementary and alternative medicine use among patients with cancer, (2) the method of use of the particular therapy, (3) the reasons for using complementary and alternative medicine therapies, (4) the benefits experienced by the use of complementary and alternative medicine, (5) the source of information about complementary and alternative medicine therapies and, (6) the satisfaction and cost of complementary and alternative medicine. Complementary and alternative medicine consists of diverse medical and healthcare systems, practices and products that are not considered at present to be a part of conventional medicine. The majority of patients who use complementary and alternative medicine use more than one method. Complementary and alternative medicine use is more common in cases of advanced disease or poor prognosis. This is a descriptive study of complementary and alternative medicine. This study was conducted in the Chemotherapy Unit at Ondokuz Mayıs University, Faculty of Medicine, Samsun, Turkey, between 18 March 2008-30 June 2008. Two hundred fifty-three patients with cancer, among 281 patients who applied to the chemotherapy clinic between these dates, agreed to take part in the study with whom contact could be made were included. A questionnaire including descriptive characteristics in collecting data, characteristics about diseases and their treatments, complementary and alternative medicine information and implementation situations and a control list about complementary and alternative medicine implementations were given. The collected data were evaluated by computer using descriptive statistics, the chi-square test and Student's t-test. In this study, 94·1% of the patients were content with medical treatment, 58·9% of them used complementary and alternative medicine treatments, 41·1% did not use any complementary and alternative medicine treatments.

An essential feature of genuine quantum correlation is the simultaneous existence of correlation in complementary bases. We reveal this feature of quantum correlation by defining measures based on invariance under a basis change. For a bipartite quantum state, the classical correlation is the maximal correlation present in a certain optimum basis, while the quantum correlation is characterized as a series of residual correlations in the mutually unbiased bases. Compared with other approaches to quantify quantum correlation, our approach gives information-theoretical measures that directly reflect the essential feature of quantum correlation. PMID:24503595

To investigate pharmacists' herbal/nutrient weight loss complementary medicine (WLCM) practices in the context of other pharmacist weight management support practices (provision of lifestyle advice, orlistat and meal replacement treatments); and gain insight into their attitudes, recommendations, information and education needs. Pharmacists from a randomly selected sample of 214 community pharmacies from different socioeconomic areas in the Greater Brisbane region, Australia, were invited to complete a survey to explore their weight management practices, with a specific focus on herbal/nutrient WLCM practices. Data collected from the sample group represented pharmacist practices within the metropolitan Greater Brisbane region. This survey achieved a 51% response rate. During weight management consultations, a high proportion of customers (37%) sought advice from community pharmacists relating to WLCMs relative to other weight management practices; however, only a small proportion (10%) of pharmacists recommended them. Most were also found to be using resources that may not be evidence-based or do not provide sufficient WLCMs' information. Study results highlight the need for pharmacy professional bodies to develop evidence-based continuing education programmes to assist consumers with popular and widely available WLCMs products. © 2015 Royal Pharmaceutical Society.

Hairpin Bisulfite Sequencing: Synchronous Methylation Analysis on Complementary DNA Strands of Individual Chromosomes.

Giehr, Pascal; Walter, Jörn

2018-01-01

The accurate and quantitative detection of 5-methylcytosine is of great importance in the field of epigenetics. The method of choice is usually bisulfite sequencing because of the high resolution and the possibility to combine it with next generation sequencing. Nevertheless, also this method has its limitations. Following the bisulfite treatment DNA strands are no longer complementary such that in a subsequent PCR amplification the DNA methylation patterns information of only one of the two DNA strand is preserved. Several years ago Hairpin Bisulfite sequencing was developed as a method to obtain the pattern information on complementary DNA strands. The method requires fragmentation (usually by enzymatic cleavage) of genomic DNA followed by a covalent linking of both DNA strands through ligation of a short DNA hairpin oligonucleotide to both strands. The ligated covalently linked dsDNA products are then subjected to a conventional bisulfite treatment during which all unmodified cytosines are converted to uracils. During the treatment the DNA is denatured forming noncomplementary ssDNA circles. These circles serve as a template for a locus specific PCR to amplify chromosomal patterns of the region of interest. As a result one ends up with a linearized product, which contains the methylation information of both complementary DNA strands.

The synthesis and subsequent genomic integration of DNA that is complementary to the genomes of non-retroviral RNA viruses are rarely observed. However, upon infection of various human cell lines and primary fibroblasts with the vesicular stomatitis virus (VSV), we detected DNA complementary to the VSV RNA. The VSV DNA was detected in the cytoplasm as single-stranded DNA fully complementary to the viral mRNA from the poly(A) region to the 7-methyl guanosine cap. The formation of this DNA was cell-dependent. Experimentally, we found that the transduction of cells that do not produce VSV DNA with the long interspersed nuclear element 1 and their infection with VSV could lead to the formation of VSV DNA. Viral DNA complementary to other RNA viruses was also detected in the respective infected human cells. Thus, the genetic information of the non-retroviral RNA virus genome can flow into the DNA of mammalian cells expressing LINE-1-like elements. PMID:24875540

Complementary medicine (CM) use is common among cancer patients. However, little is known about CM products that are utilised during radiotherapy and/or chemotherapy. Out of 62 cancer patients who completed a specialised survey, 35 (56%) consumed some type of CM during active anti-cancer therapy. Cancer patients reported the use of herbal teas (52%), vitamins and other dietary supplements (45%), vegetables and juices (39%), special diets (19%), herbal medicines, including Chinese medicines (19%) and 'immunomodulators' (3%). Most of patients (86%) consumed CM products every day. However, nearly 47% of CM users did not admit this to their oncologists. Majority of CM users (85%) were convinced that supplementary products increase the efficacy of standard anti-cancer therapy and prolong their survival. Information about CM was mainly obtained through internet sources (36%), books and brochures (25%). Although most CM users (82%) trusted the received information, 73% of them admitted that additional information about CM methods would be necessary. Patients would like to receive additional information through a specialised consultation (60%), but also from brochures (44%) and the internet (20%). Adequate counselling of patients is of paramount importance since some CM methods may cause significant side effects and decrease the efficacy of radiotherapy and/or chemotherapy. © 2013 John Wiley & Sons Ltd.

The uncertainty relations, pioneered by Werner Heisenberg nearly 90 years ago, set a fundamental limitation on the joint measurability of complementary observables. This limitation has long been a subject of debate, which has been reignited recently due to new proposed forms of measurement uncertainty relations. The present work is associated with a new error trade-off relation for compatible observables approximating two incompatible observables, in keeping with the spirit of Heisenberg’s original ideas of 1927. We report the first direct test and confirmation of the tight bounds prescribed by such an error trade-off relation, based on an experimental realisation of optimal joint measurements of complementary observables using a single ultracold {}40{{{Ca}}}+ ion trapped in a harmonic potential. Our work provides a prototypical determination of ultimate joint measurement error bounds with potential applications in quantum information science for high-precision measurement and information security.

Complementary and Alternative Medicine and Osteoarthritis.

Wang, Chenchen

2013-01-01

Patients with osteoarthritis experience high levels of pain, psychological distress and have limited therapeutic options. Emerging evidence from clinical trials suggests that both acupuncture and Tai Chi mind-body therapies are safe and effective treatments for osteoarthritis. Acupuncture has effects over and above those of 'sham acupuncture' and the most robust evidence to date demonstrates that acupuncture does have short-term benefits and is a reasonable referral option for patients with symptomatic osteoarthritis. Tai Chi is a mind-body exercise that enhances cardiovascular fitness, muscular strength, balance, and physical function. It also appears to be associated with reduced stress and anxiety and depression, as well as improved quality of life. Thus, Tai Chi may be safely recommended to patients with osteoarthritis as a complementary and alternative medical approach to affect patient well-being. Integrative approaches combine the best of conventional medicine and complementary and alternative medicine to ultimately improve patient care. These modalities may lead to the development of better disease modifying strategies that could improve symptoms and decrease the progression of osteoarthritis. This overview synthesizes the current body of knowledge about Chinese mind-body medicine to better inform clinical decision-making for our rheumatic patients.

Depression is one of the most common reasons for using complementary and alternative therapies. The aim of this article is to provide an overview of the evidence available on the treatment of depression with complementary therapies. Systematic literature searches were performed using several databases, reference list searching, and inquiry to colleagues. Data extraction followed a predefined protocol. The amount of rigorous scientific data to support the efficacy of complementary therapies in the treatment of depression is extremely limited. The areas with the most evidence for beneficial effects are exercise, herbal therapy (Hypericum perforatum), and, to a lesser extent, acupuncture and relaxation therapies. There is a need for further research involving randomized controlled trials into the efficacy of complementary and alternative therapies in the treatment of depression.

Complementary health insurance is increasingly used to remedy the limitations and shortcomings of the basic health insurance benefit packages. Hence, it is essential to gather reliable information about the amount of Willingness to Pay (WTP) for health insurance. We assessed the WTP for health insurance in Iran in order to suggest an affordable complementary health insurance. The study sample consisted of 300 household heads all over provinces of Iran in 2013. The method applied was double bounded dichotomous choice and open-ended question approach of contingent valuation. The average WTP for complementary health insurance per person per month by double bounded dichotomous choice and open-ended question method respectively was 199000 and 115300 Rials (8 and 4.6 USD, respectively). Household's heads with higher levels of income and those who worked had more WTP for the health insurance. Besides, the WTP increased in direct proportion to the number of insured members of each household and in inverse proportion to the family size. The WTP value can be used as a premium in a society. As an important finding, the study indicated that the households were willing to pay higher premiums than currently collected for the complementary health insurance coverage in Iran. This offers the policy makers the opportunity to increase the premium and provide good benefits package for insured people of country then better risk pooling.

To determine the prevalence and types of complementary and alternative medicine therapies used by certified nurse-midwives in North Carolina. Surveys were sent to all 120 licensed certified nurse-midwives in North Carolina requesting information concerning their recommendations for use of complementary and alternative medicine for their pregnant or postpartum patients. Eighty-two responses were received (68.3%). Seventy-seven (93.9%) reported recommending complementary and alternative medicine to their pregnant patients in the past year. Forty-seven (57.3%) reported recommending complementary and alternative medicine to more than 10% of patients. The percentage of nurse-midwives who recommended each type of complementary and alternative medicine was as follows: herbal therapy (73.2%), massage therapy (67.1%), chiropractic (57.3%), acupressure (52.4%), mind-body interventions (48.8%), aromatherapy (32.9%), homeopathy (30.5%), spiritual healing (23.2%), acupuncture (19.5%), and bioelectric or magnetic applications (14.6%). The 60 respondents who reported prescribing herbal therapies gave them for the following indications: nausea and vomiting, labor stimulation, perineal discomfort, lactation disorders, postpartum depression, preterm labor, postpartum hemorrhage, labor analgesia, and malpresentation. Complementary and alternative medicine, especially herbal therapy, is commonly prescribed to pregnant women by nurse-midwives in North Carolina.

Optimal infant nutrition comprises exclusive breastfeeding, with complementary foods introduced from six months of age. How parents make decisions regarding this is poorly studied. This study begins to address the dearth of research into the decision-making processes used by first-time mothers relating to the introduction of complementary foods. This qualitative explorative study was conducted using interviews (13) and focus groups (3). A semi-structured interview guide based on the Theory of Planned Behaviour (TPB). The TPB, a well-validated decision-making model, identifies the key determinants of a behaviour through behavioural beliefs, subjective norms, and perceived behavioural control over the behaviour. It is purported that these beliefs predict behavioural intention to perform the behaviour, and performing the behaviour. A purposive, convenience, sample of 21 metropolitan parents recruited through advertising at local playgroups and childcare centres, and electronically through the University community email list self-selected to participate. Data were analysed thematically within the theoretical constructs: behavioural beliefs, subjective norms and perceived behavioural control. Data relating to sources of information about the introduction of complementary foods were also collected. Overall, first-time mothers found that waiting until six months was challenging despite knowledge of the WHO recommendations and an initial desire to comply with this guideline. Beliefs that complementary foods would assist the infants' weight gain, sleeping patterns and enjoyment at meal times were identified. Barriers preventing parents complying with the recommendations included subjective and group norms, peer influences, infant cues indicating early readiness and food labelling inconsistencies. The most valued information source was from peers who had recently introduced complementary foods. First-time mothers in this study did not demonstrate a good understanding of the

The trial was conducted at two public hospitals, and through the Western Sydney University in Sydney, Australia. the Complementary Therapies for Labour and Birth (CTLB) protocol, based on the She Births® course and the Acupressure for labour and birth protocol, incorporated six evidence-based complementary medicine (CM) techniques; acupressure, relaxation, visualisation, breathing, massage, yoga techniques and incorporated facilitated partner support. Randomisation to the trial occurred at 24-36 weeks' gestation, and participants attended a two-day antenatal education programme, plus standard care, or standard care alone. the overarching theme identified in the qualitative data was making sense of labour and birth. Women used information about normal birth physiology from the course to make sense of labour, and to utilise the CM techniques to support normal birth and reduce interventions in labour. Women's, partners' and midwives' experience of the course and its use during birth gave rise to supporting themes such as: working for normal; having a toolkit; and finding what works. the Complementary Therapies for Labour and Birth Study provided women and their partners with knowledge to understand the physiology of normal labour and birth and enabled them to use evidence-based CM tools to support birth and reduce interventions. the Complementary Therapies for Labour and Birth Study introduces concepts of what

Complementary and alternative medicine are frequently used by cancer patients. The main benefit of complementary medicine is that it gives patients the chance to become active. Complementary therapy can reduce the side effects of conventional therapy. However, we have to give due consideration to side effects and interactions: the latter being able to reduce the effectiveness of cancer therapy and so to jeopardise the success of therapy. Therefore, complementary therapy should be managed by the oncologist. It is based on a common concept of cancerogenesis with conventional therapy. Complement therapy can be assessed in studies. Alternative medicine in contrast rejects common rules of evidence-based medicine. It starts from its own concepts of cancerogenesis, which is often in line with the thinking of lay persons. Alternative medicine is offered as either "alternative" to recommended cancer treatment or is used at the same time but without due regard for the interactions. Alternative medicine is a high risk to patients. In the following two parts of the article, the most important complementary and alternative therapies cancer patients use nowadays are presented and assessed according to published evidence.

This study reviewed existing literature to investigate how frequently nurses include complementary and alternative forms of medicine in their clinical practice. In so doing, we investigated nurses' knowledge of and attitudes towards complementary and alternative medicine as well as their ability to communicate the risks and benefits of these therapies with patients. Little information is available concerning nurses' knowledge and attitudes towards complementary and alternative medicine or how they incorporate these therapies into their practice. In addition, little is known about the ability of nurses to communicate the risks and benefits of complementary and alternative medicine to their patients. This study used a scoping review method to map and synthesise existing literature. Both electronic and manual searches were used to identify relevant studies published between January 2007 and January 2014. The review was conducted in five stages: (1) identification of research question(s), (2) locate studies, (3) selection of studies, (4) charting of data, and (5) collating, summarising, and reporting of results. Fifteen papers met the inclusion criteria for this review, among which 53·7% referenced how frequently nurses include complementary and alternative medicine in their practice. We found that 66·4% of nurses had positive attitudes towards complementary and alternative medicine; however, 77·4% did not possess a comprehensive understanding of the associated risks and benefits. In addition, nearly half of the respondents (47·3-67·7%) reported feeling uncomfortable discussing complementary and alternative medicine therapies with their patients. The lack of knowledge about complementary and alternative medicine among nurses is a cause for concern, particularly in light of its widespread application. Findings from this study suggest that health care professionals need to promote evidence informed decision-making in complementary and alternative medicine practice

Despite limited evidence, complementary and alternative medicine treatments are popular in autism spectrum disorder. The aim of this review was to summarize the available evidence on complementary and alternative medicine use frequency in autism spectrum disorder. A systematic search of three electronic databases was performed. All research studies in English or German reporting data on the frequency of complementary and alternative medicine use in individuals with autism spectrum disorder were included. Two independent reviewers searched the literature, extracted information on study design and results, and assessed study quality using an established quality assessment tool. Twenty studies with a total of 9540 participants were included. The prevalence of any complementary and alternative medicine use ranged from 28% to 95% (median: 54%). Special diets or dietary supplements (including vitamins) were the most frequent complementary and alternative medicine treatments, ranking first in 75% of studies. There was some evidence for a higher prevalence of complementary and alternative medicine use in autism spectrum disorder compared to other psychiatric disorders and the general population. Approximately half of children and adolescents with autism spectrum disorder use complementary and alternative medicine. Doctors should be aware of this and should discuss complementary and alternative medicine use with patients and their carers, especially as the evidence is mixed and some complementary and alternative medicine treatments are potentially harmful.

Understanding the perceived need for complementary and alternative nutraceuticals: lifestyle issues.

Whitman, M

2001-01-01

Nutraceuticals are biological therapies used to promote wellness, prevent malignant processes, and control symptoms. The use of complementary and alternative nutraceuticals increased dramatically after passage of the Dietary Supplement and Health Education Act of 1994. Motivations for use of these products include changes in eating patterns, concerns about adequacy of consumer food supply, and interactions with conventional healthcare providers that are perceived to be insensitive, too brief, or uncaring. By becoming knowledgeable about complementary and alternative nutraceuticals and the nutritional needs of people with cancer, communicating with empathy and patience, and involving dietitians, pharmacist, and other professional providers as needed, oncology nurses can provide accurate information and support for people with cancer and their families.

We analyzed characteristics, motivation, and effectiveness of complementary and alternative medicine in a large sample of people with multiple sclerosis. A 53-item survey was mailed to the members of the German Multiple Sclerosis Society, chapter of Baden-Wuerttemberg. Surveys of 1573 patients (48.5 +/- 11.7 years, 74% women, duration of illness 18.1 +/- 10.5 years) were analyzed. In comparison with conventional medicine, more patients displayed a positive attitude toward complementary and alternative medicine (44% vs 38%, P < 0.05), with 70% reporting lifetime use of at least one method. Among a wide variety of complementary and alternative medicine, diet modification (41%), Omega-3 fatty acids (37%), removal of amalgam fillings (28%), vitamins E (28%), B (36%), and C (28%), homeopathy (26%), and selenium (24%) were cited most frequently. Most respondents (69%) were satisfied with the effects of complementary and alternative medicine. Use of complementary and alternative medicine was associated with religiosity, functional independence, female sex, white-collar job, and higher education (P < 0.05). Compared with conventional therapies, complementary and alternative medicine rarely showed unwanted side effects (9% vs 59%, P < 0.00001). A total of 52% stated that the initial consultation with their physician lasted less than 15 min. To conclude, main reasons for the use of complementary and alternative medicine include the high rate of side effects and low levels of satisfaction with conventional treatments and brief patients/physicians contacts.

Determining Complementary Properties with Quantum Clones.

In a classical world, simultaneous measurements of complementary properties (e.g., position and momentum) give a system's state. In quantum mechanics, measurement-induced disturbance is largest for complementary properties and, hence, limits the precision with which such properties can be determined simultaneously. It is tempting to try to sidestep this disturbance by copying the system and measuring each complementary property on a separate copy. However, perfect copying is physically impossible in quantum mechanics. Here, we investigate using the closest quantum analog to this copying strategy, optimal cloning. The coherent portion of the generated clones' state corresponds to "twins" of the input system. Like perfect copies, both twins faithfully reproduce the properties of the input system. Unlike perfect copies, the twins are entangled. As such, a measurement on both twins is equivalent to a simultaneous measurement on the input system. For complementary observables, this joint measurement gives the system's state, just as in the classical case. We demonstrate this experimentally using polarized single photons.

Breastfeeding provides the ideal food during the first 6 months of life. Complementary feeding starts when breast milk is no longer sufficient by itself, where the target age is for 6–23 months. The gap between nutritional requirement and amount obtained from breast milk increases with age. For energy, 200, 300, and 550 kcal per day is expected to be covered by complementary foods at 6–8, 9–11, and 12–23 months, respectively. In addition, the complementary foods must provide relatively large proportions of micronutrients such as iron, zinc, phosphorus, magnesium, calcium, and vitamin B6. In several parts of the developing world, complementary feeding continues as a challenge to good nutrition in children. In Ethiopia, only 4.2% of breastfed children of 6–23 months of age have a minimum acceptable diet. The gaps are mostly attributed to either poor dietary quality or poor feeding practices, if not both. Commercial fortified foods are often beyond the reach of the poor. Thus, homemade complementary foods remain commonly used. Even when based on an improved recipe, however, unfortified plant-based complementary foods provide insufficient key micronutrients (especially, iron, zinc, and calcium) during the age of 6–23 months. Thus, this review assessed complementary feeding practice and recommendation and reviewed the level of adequacy of homemade complementary foods. PMID:27800479

Background State parties to human rights conventions and declarations are often faced with the seemingly contradictory problem of having an obligation to protect people from harmful practices while also having an obligation to enable access to culturally appropriate effective healing. As people increasingly migrate across the globe, previous distinctions between ‘traditional’ and ‘complementary and alternative medicine’ practices are being transcended. There are connections across transnational healing pathways that link local, national, and global movements of people and knowledge. Objective This paper contributes to the development of the concept and practice of the right to health in all its forms, exploring the right to traditional, complementary, and alternative health (R2TCAH) across different contexts. Design The paper draws on four settings – England, South Africa, Kenya, and Jordan – and is based on key informant interviews and a literature review undertaken in 2010, and updated in 2013. The paper begins by reviewing the international legal context for the right to health. It then considers legal and professional regulations from the global north and south. Results Additional research is needed to establish the legal basis, compare regulatory frameworks, and explore patient and provider perspectives of regulation. This leads to being able to make recommendations on how to balance protection from harm and the obligation to ensure culturally appropriate services. Such an exploration must also challenge Western theories of human rights. Key concepts, such as individual harm, consent, and respect of the autonomy of the individual already established and recognised in international health law, could be adopted in the development of a template for future comparative research. Conclusions Exploration of the normative content of the right to health in all its forms will contribute to supporting traditional, complementary, and alternative health service

Plant roots are known to modify physical, chemical and biological properties of the rhizosphere, thereby, altering conditions for water and nutrient uptake. We aim for capturing the dynamic processes occurring at the soil-root interface in situ. A combination of neutron (NI), magnetic resonance (MRI) and micro-focus X-ray tomography (CT) is applied to monitor the rhizosphere of young plants grown in sandy soil in cylindrical containers (diameter 3 cm). A novel transportable low field MRI system is operated directly at the neutron facility allowing for combined measurements of the very same sample capturing the same hydro-physiological state. The combination of NI, MRI and CT provides three-dimensional access to the root system in respect to structure and hydraulics of the rhizosphere and the transport of dissolved marker substances. The high spatial resolution of neutron imaging and its sensitivity for water can be exploited for the 3D analysis of the root morphology and detailed mapping of three-dimensional water content at the root soil interface and the surrounding soil. MRI has the potential to yield complementary information about the mobility of water, which can be bound in small pores or in the polymeric network of root exudates (mucilage layer). We inject combined tracers (GdDPTA or D2O) to study water fluxes through soil, rhizosphere and roots. Additional CT measurements reveal mechanical impacts of roots on the local microstructure of soil, e.g. showing soil compaction or the formation of cracks. We co-register the NT, MRI and CT data to integrate the complementary information into an aligned 3D data set. This allows, e.g., for co-localization of compacted soil regions or cracks with the specific local soil hydraulics, which is needed to distinguish the contribution of root exudation from mechanical impacts when interpreting altered hydraulic properties of the rhizosphere. Differences between rhizosphere and bulk soil can be detected and interpreted in

The guideline is a reliable repository of information for advocating or not recommending certain CAM treatments in MS. It eases the burden of searching for information on each separate CAM treatment. It frequently emphasizes the need for patient counseling. To provide such generally undervalued, but needed, cognitive services, neurologists could use advanced practice providers and patient-friendly visual aids during or between visits. They should also rely on evaluation and management codes that recognize time spent predominantly on counseling or coordination of care. The guideline's categorization of probable effectiveness of certain therapies will not influence coverage decisions because payers do not generally cover CAM therapies. PMID:29443184

Investigations of the mechanisms of touch perception and decoding has been hampered by difficulties in achieving invariant patterns of skin sensor activation. To obtain reproducible spatiotemporal patterns of activation of sensory afferents, we used an artificial fingertip equipped with an array of neuromorphic sensors. The artificial fingertip was used to transduce real-world haptic stimuli into spatiotemporal patterns of spikes. These spike patterns were delivered to the skin afferents of the second digit of rats via an array of stimulation electrodes. Combined with low-noise intra- and extracellular recordings from neocortical neurons in vivo, this approach provided a previously inaccessible high resolution analysis of the representation of tactile information in the neocortical neuronal circuitry. The results indicate high information content in individual neurons and reveal multiple novel neuronal tactile coding features such as heterogeneous and complementary spatiotemporal input selectivity also between neighboring neurons. Such neuronal heterogeneity and complementariness can potentially support a very high decoding capacity in a limited population of neurons. Our results also indicate a potential neuroprosthetic approach to communicate with the brain at a very high resolution and provide a potential novel solution for evaluating the degree or state of neurological disease in animal models.

Detraditionalisation, gender and alternative and complementary medicines.

PubMed

Sointu, Eeva

2011-03-01

This article is premised on the importance of locating the appeal and meaning of alternative and complementary medicines in the context of gendered identities. I argue that the discourse of wellbeing--captured in many alternative and complementary health practices--is congruent with culturally prevalent ideals of self-fulfilling, authentic, unique and self-responsible subjectivity. The discourse of wellbeing places the self at the centre, thus providing a contrast with traditional ideas of other-directed and caring femininity. As such, involvement in alternative and complementary medicines is entwined with a negotiation of shifting femininities in detraditionalising societies. Simultaneously, many alternative and complementary health practices readily tap into and reproduce traditional representations of caring femininity. It is through an emphasis on emotional honesty and intimacy that the discourse of wellbeing also captures a challenge to traditional ideas of masculinity. Expectations and experiences relating to gender add a further level of complexity to the meaningfulness and therapeutic value of alternative and complementary medicines and underlie the gender difference in the utilisation of holistic health practices. I draw on data from a qualitative study with 44, primarily white, middle-class users and practitioners of varied alternative and complementary medicines in the UK. © 2010 The Author.

The purpose of this study was to investigate the ability of computed tomography texture analysis (CTTA) to provide additional prognostic information in patients with Hodgkin's lymphoma (HL) and high-grade non-Hodgkin's lymphoma (NHL). This retrospective, pilot-study approved by the IRB comprised 45 lymphoma patients undergoing routine 18F-FDG-PET-CT. Progression-free survival (PFS) was determined from clinical follow-up (mean-duration: 40 months; range: 10-62 months). Non-contrast-enhanced low-dose CT images were submitted to CTTA comprising image filtration to highlight features of different sizes followed by histogram-analysis using kurtosis. Prognostic value of CTTA was compared to PET FDG-uptake value, tumour-stage, tumour-bulk, lymphoma-type, treatment-regime, and interim FDG-PET (iPET) status using Kaplan-Meier analysis. Cox regression analysis determined the independence of significantly prognostic imaging and clinical features. A total of 27 patients had aggressive NHL and 18 had HL. Mean PFS was 48.5 months. There was no significant difference in pre-treatment CTTA between the lymphoma sub-types. Kaplan-Meier analysis found pre-treatment CTTA (medium feature scale, p=0.010) and iPET status (p<0.001) to be significant predictors of PFS. Cox analysis revealed that an interaction between pre-treatment CTTA and iPET status was the only independent predictor of PFS (HR: 25.5, 95% CI: 5.4-120, p<0.001). Specifically, pre-treatment CTTA risk stratified patients with negative iPET. CTTA can potentially provide prognostic information complementary to iPET for patients with HL and aggressive NHL. • CT texture-analysis (CTTA) provides prognostic information complementary to interim FDG-PET in Lymphoma. • Pre-treatment CTTA and interim PET status were significant predictors of progression-free survival. • Patients with negative interim PET could be further stratified by pre-treatment CTTA. • Provide precision surveillance where additional imaging reserved for

Anthropic Correction of Information Estimates and Its Application to Neural Coding

Information theory has been used as an organizing principle in neuroscience for several decades. Estimates of the mutual information (MI) between signals acquired in neurophysiological experiments are believed to yield insights into the structure of the underlying information processing architectures. With the pervasive availability of recordings from many neurons, several information and redundancy measures have been proposed in the recent literature. A typical scenario is that only a small number of stimuli can be tested, while ample response data may be available for each of the tested stimuli. The resulting asymmetric information estimation problem is considered. It is shown that the direct plug-in information estimate has a negative bias. An anthropic correction is introduced that has a positive bias. These two complementary estimators and their combinations are natural candidates for information estimation in neuroscience. Tail and variance bounds are given for both estimates. The proposed information estimates are applied to the analysis of neural discrimination and redundancy in the avian auditory system.

Using the minimal parameter sequence of a given chain sequence, we introduce the concept of complementary chain sequences, which we view as perturbations of chain sequences. Using the relation between these complementary chain sequences and the corresponding Verblunsky coefficients, the para-orthogonal polynomials and the associated Szegő polynomials are analyzed. Two illustrations, one involving Gaussian hypergeometric functions and the other involving Carathéodory functions are also provided. A connection between these two illustrations by means of complementary chain sequences is also observed.

High-throughput complementary DNA sequencing (RNA-Seq) is a powerful tool for whole-transcriptome analysis, supplying information about a transcript's expression level and structure. However, it is difficult to determine the polarity of transcripts, and therefore identify which strand is transcribed. Here, we present a simple cDNA sequencing protocol that preserves information about a transcript's direction. Using Saccharomyces cerevisiae and mouse brain transcriptomes as models, we demonstrate that knowing the transcript's orientation allows more accurate determination of the structure and expression of genes. It also helps to identify new genes and enables studying promoter-associated and antisense transcription. The transcriptional landscapes we obtained are available online. PMID:19620212

The use of complementary and alternative medicine (CAM) has become increasingly prevalent in industrialised countries, with women being the most prolific users. Some women continue to consume these therapies when they become pregnant. To review the literature exploring prevalence and motivation for use of complementary and alternative medicine by pregnant women. A search for relevant literature published from 2001 was undertaken using a range of databases and by examining relevant bibliographies. Although the estimates vary widely from 1% to 87%, the general trend indicates that a significant number of pregnant women use complementary and alternative medicine. Common modalities used include massage, vitamin and mineral supplements, herbal medicine, relaxation therapies and aromatherapy. Reasons for use are varied and include the belief that these therapies offer safe alternatives to pharmaceuticals, they allow greater choice and control over the childbearing experiences, and they are congruent with their holistic health beliefs. The influence of traditional cultural practices on the use of these therapies is unclear. Most expectant women rely on advice from family and friends, and many do not disclose their use to their pregnancy care providers. Many women use complementary and alternative medicine when they are pregnant. Further research is needed to gain a greater understanding of the true prevalence and expectant women's motivation for the use of complementary and alternative medicine. Health-care professionals are encouraged to ask women about their use of these treatments and seek out relevant information. Copyright © 2010 Elsevier Ltd. All rights reserved.

Pointwise Partial Information Decomposition Using the Specificity and Ambiguity Lattices

NASA Astrophysics Data System (ADS)

Finn, Conor; Lizier, Joseph

2018-04-01

What are the distinct ways in which a set of predictor variables can provide information about a target variable? When does a variable provide unique information, when do variables share redundant information, and when do variables combine synergistically to provide complementary information? The redundancy lattice from the partial information decomposition of Williams and Beer provided a promising glimpse at the answer to these questions. However, this structure was constructed using a much criticised measure of redundant information, and despite sustained research, no completely satisfactory replacement measure has been proposed. In this paper, we take a different approach, applying the axiomatic derivation of the redundancy lattice to a single realisation from a set of discrete variables. To overcome the difficulty associated with signed pointwise mutual information, we apply this decomposition separately to the unsigned entropic components of pointwise mutual information which we refer to as the specificity and ambiguity. This yields a separate redundancy lattice for each component. Then based upon an operational interpretation of redundancy, we define measures of redundant specificity and ambiguity enabling us to evaluate the partial information atoms in each lattice. These atoms can be recombined to yield the sought-after multivariate information decomposition. We apply this framework to canonical examples from the literature and discuss the results and the various properties of the decomposition. In particular, the pointwise decomposition using specificity and ambiguity satisfies a chain rule over target variables, which provides new insights into the so-called two-bit-copy example.

Ambipolar transistors are ideal candidates for the simple and low-cost development of complementary logic circuits since they can operate as n-type and p-type transistors. Nevertheless, the experimental demonstration of ambipolar organic complementary circuits is limited to inverters. The control of the transistor polarity is crucial for proper circuit operation. Novel gating techniques enable to control the transistor polarity but result in dramatically reduced performances. Here we show high-performance non-planar ambipolar organic transistors with electrical control of the polarity and orders of magnitude higher performances with respect to state-of-art split-gate ambipolar transistors. Electrically reconfigurable complementary logic gates based on ambipolar organic transistors are experimentally demonstrated, thus opening up new opportunities for ambipolar organic complementary electronics.

Carbon nanotubes and metal oxide semiconductors have emerged as important materials for p-type and n-type thin-film transistors, respectively; however, realizing sophisticated macroelectronics operating in complementary mode has been challenging due to the difficulty in making n-type carbon nanotube transistors and p-type metal oxide transistors. Here we report a hybrid integration of p-type carbon nanotube and n-type indium-gallium-zinc-oxide thin-film transistors to achieve large-scale (>1,000 transistors for 501-stage ring oscillators) complementary macroelectronic circuits on both rigid and flexible substrates. This approach of hybrid integration allows us to combine the strength of p-type carbon nanotube and n-type indium-gallium-zinc-oxide thin-film transistors, and offers high device yield and low device variation. Based on this approach, we report the successful demonstration of various logic gates (inverter, NAND and NOR gates), ring oscillators (from 51 stages to 501 stages) and dynamic logic circuits (dynamic inverter, NAND and NOR gates).

A silicon-on-insulator complementary-metal-oxide-semiconductor compatible flexible electronics technology

Tu, Hongen; Xu, Yong

2012-07-01

This paper reports a simple flexible electronics technology that is compatible with silicon-on-insulator (SOI) complementary-metal-oxide-semiconductor (CMOS) processes. Compared with existing technologies such as direct fabrication on flexible substrates and transfer printing, the main advantage of this technology is its post-SOI-CMOS compatibility. Consequently, high-performance and high-density CMOS circuits can be first fabricated on SOI wafers using commercial foundry and then be integrated into flexible substrates. The yield is also improved by eliminating the transfer printing step. Furthermore, this technology allows the integration of various sensors and microfluidic devices. To prove the concept of this technology, flexible MOSFETs have been demonstrated.

Wild animals substantially support crop production by providing ecosystem services, such as pollination and natural pest control. However, the strengths of synergies between ecosystem services and their dependencies on land-use management are largely unknown. Here, we took an experimental approach to test the impact of land-use intensification on both individual and combined pollination and pest control services in coffee production systems at Mount Kilimanjaro. We established a full-factorial pollinator and vertebrate exclosure experiment along a land-use gradient from traditional homegardens (agroforestry systems), shaded coffee plantations to sun coffee plantations (total sample size = 180 coffee bushes). The exclusion of vertebrates led to a reduction in fruit set of ca 9%. Pollinators did not affect fruit set, but significantly increased fruit weight of coffee by an average of 7.4%. We found no significant decline of these ecosystem services along the land-use gradient. Pest control and pollination service were thus complementary, contributing to coffee production by affecting the quantity and quality of a major tropical cash crop across different coffee production systems at Mount Kilimanjaro.

A high proportion of cancer patients use complementary and alternative medicine (CAM). In oncology, risks of CAM are side effects and interactions. Our aim was to conduct a survey on professionals in palliative care regarding attitudes toward CAM. An internet-based survey with a standardized questionnaire was sent to all members of the German Society for Palliative Care. The questionnaire collected data on attitude toward CAM and experiences. Six hundred and ninety questionnaires (19 %) were returned (49 % physicians, 35 % nurses, 3 % psychologists). Acceptance of CAM is high (92 % for complementary and 54 % for alternative medicine). Most participants had already been asked on CAM by patients (95 %) and relatives (89 %). Forty-four percent already had used complementary methods and 5 % alternative methods. Only 21 % think themselves adequately informed. Seventy-four percent would use complementary methods in a patient with advanced tumor, and 62 % would use alternative therapy in patients if there was no other therapy. Even from those who are skeptical 45 % would treat a patient with alternative methods. In order to inform patients on CAM and to further patients' autonomy, evidence on benefits and harms of CAM must be provided. As awareness of risks from CAM is low and critical appraisal especially of alternative medicine missing, but interest on information on CAM is high, experts should provide evidence-based recommendations for CAM in palliative care to members of different professions. This could be done by a curriculum focusing on the most often used CAM methods.

Breast cancer survivors often turn to the internet as an information resource when deciding whether to use complementary and alternative medicine (CAM) but their use of online CAM-related resources is poorly understood. The objective was to explore breast cancer survivors' use of the internet when making decisions about CAM use. A purposive sample of 11 breast cancer survivors (mean age=56) completed a quantitative questionnaire and a qualitative telephone interview. The theory of planned behaviour (TPB) was used to guide interview questions. Framework analysis and descriptive statistics were used. United Kingdom. All participants found information on CAM using the internet and used some form of CAM after their diagnosis. Themes from the interviews went beyond the standard definitions of the TPB areas. Despite the lack of approval from their social network and healthcare team, participants used the internet to find information on CAM. Further, participants' cancer diagnosis changed their needs, transforming how they perceived and experienced the internet CONCLUSIONS: Participants' use of the internet was more complex than can easily be explained by the TPB and was inherently connected to the experience of self-management for the consequences of cancer and its treatment. As breast cancer survivors may not disclose their use of the internet to their healthcare team, healthcare professionals need to be aware that the information available on the internet plays a factor in the decision-making process to use CAM.

Complementary and Alternative Therapies for Chronic Constipation

PubMed Central

2015-01-01

Chronic constipation, an ancient disease, is prevalent, and costly in the general population. Complementary and alternative therapies are frequently used for constipation. This review introduces various methods of complementary and alternative therapies, including acupuncture, moxibustion, massage, and herbal medicine. Efficacy, safety, influence factors, sham control design, and mechanisms of these therapies are discussed and evaluated. Acupuncture or electroacupuncture was found to be most commonly used for constipation among these complementary and alternative therapies, followed by herbal medicine. Although only a small number of clinical studies are flawless, our review of the literature seems to suggest that acupuncture or electroacupuncture and herbal medicine are effective in treating constipation, whereas findings on massage and moxibustion are inconclusive. More well-designed clinical trials are needed to improve and prove the efficacy of the complementary and alternative therapies for constipation; mechanistic studies that would lead to wide spread use and improvement of the methods are also discussed in this review.

Soviet test yields

Vergino, Eileen S.

Soviet seismologists have published descriptions of 96 nuclear explosions conducted from 1961 through 1972 at the Semipalatinsk test site, in Kazakhstan, central Asia [Bocharov et al., 1989]. With the exception of releasing news about some of their peaceful nuclear explosions (PNEs) the Soviets have never before published such a body of information.To estimate the seismic yield of a nuclear explosion it is necessary to obtain a calibrated magnitude-yield relationship based on events with known yields and with a consistent set of seismic magnitudes. U.S. estimation of Soviet test yields has been done through application of relationships to the Soviet sites based on the U.S. experience at the Nevada Test Site (NTS), making some correction for differences due to attenuation and near-source coupling of seismic waves.

Age of complementary foods introduction is associated with childhood anemia, but the ideal age for the introduction of complementary foods to infants is a continuing topic of debate. We examined the longitudinal association between complementary foods introduction age and risk of anemia in 18,446 children from the Jiaxing Birth Cohort, who had detailed complementary feeding records at 3 and 6 months of age and had hemoglobin concentrations measured at 4-6 years. Early introduction of complementary foods at 3-6 months of age was significantly associated with a higher risk of anemia (odds ratio = 1.14; 95% confidence interval: 1.01-1.28) and a lower hemoglobin concentration of -0.84 g/L (95% confidence interval: -1.33 to -0.35) in children aged 4-6 years, compared with those fed complementary foods starting at 6 months of age. When it comes to the specific type of complementary foods, early introduction of all plant-based foods was associated with increased anemia risks and lower hemoglobin concentrations, while early introduction of most animal-based foods was not. These findings may be informative regarding the appropriate time to introduce complementary foods in infants.

The TMG and OL systems were faster than the XRP and the OL had the widest latitude. The maximum number of details perceived was similar for all three systems. The results support the suggestion that the TMG and OL systems permit more information to be perceived than XRP and that the newer imaging systems do not lose information despite their increased speed.

According to PAHO and WHO, supplementary feeding is the process that begins when human milk is insufficient to meet the nutritional needs of an infant and requires other foods and liquids. The decision to begin complementary feeding depends on socio-economic, physiological, nutritional and psychological factors. The maturation of the neuromuscular, gastrointestinal and renal system influences the chances of success of supplementary feeding. Reflexes and skills in a child with normal development can be expected and the consistency of foods can provide a way to, on one hand allow the ingestion of food and the other to allow the children to exercise their reflexes to enhance neuromuscular maturation. WHO recommends exclusive breastfeeding promotion to six months, as there are several benefits to mother and child; in Mexico, the NOM-043-SSA2-2005 promotes complementary feeding from 6 months. It should be noted that the order of introduction is not definitive and that the literature shows different patterns of input according to the needs of children and their socio-economic and cultural environment. Parents and caregivers select and buy food, model, and establish rules of behavior at home related to food. Evidence suggest that environmental factors acting at an early stage of development of small modeling preferences and eating behaviors.

What should students learn about complementary and alternative medicine?

With thousands of complementary and alternative medicine (CAM) treatments currently being used in the United States today, it is challenging to design a concise body of CAM content which will fit into already overly full curricula for health care students. The purpose of this article is to outline key principles which 15 National Center for Complementary and Alternative Medicine-funded education programs found useful when developing CAM course-work and selecting CAM content. Three key guiding principles are discussed: teach foundational CAM competencies to give students a framework for learning about CAM; choose specific content on the basis of evidence, demographics and condition (what conditions are most appropriate for CAM therapies?); and finally, provide students with skills for future learning, including where to find reliable information about CAM and how to search the scientific literature and assess the results of CAM research. Most of the programs developed evidence-based guides to help students find reliable CAM resources. The cumulative experiences of the 15 programs have been compiled, and an annotated table outlining the most highly recommended resources about CAM is presented.

To estimate the prevalence, indications, and associated factors for complementary and alternative medicine use during the last trimester of pregnancy. A questionnaire survey was conducted of women with a live birth (N=700) admitted to the postnatal unit at the Royal Aberdeen Maternity Hospital, northeast Scotland. Outcome measures included: complementary and alternative medicine used; vitamins and minerals used; reasons for complementary and alternative medicine use; independent associated factors for use; views; and experiences. Descriptive and inferential statistical analysis was performed. The response rate was 79.6% of eligible women. Two thirds of respondents (61.4%) reported using complementary and alternative medicine, excluding vitamins and minerals, during the third trimester. Respondents reported using a total of 30 different complementary and alternative medicine modalities, of which oral herbal products were the most common (38% of respondents, 40 different products). The independent associated factors for complementary and alternative medicine use identified were: complementary and alternative medicine use before pregnancy (odds ratio [OR] 4.36, 95% confidence interval [CI] 2.39-7.95, P<.001); a university education (OR 2.41, 95% CI 1.46-4.0, P=.001), and complementary and alternative medicine use by family or friends (OR 2.36, 95% CI 1.61-3.47, P<.001). There was no association with health care professional recommendations. Users were significantly more likely than nonusers to agree that complementary and alternative medicines were safer than prescribed medicines (P=.006), less likely to be associated with side effects (P≤.001), and could interfere with conventional medicines (P≤.001). Despite the majority of respondents, and notably users, being uncertain about their safety and effectiveness, complementary and alternative medicine modalities and complementary and alternative medicine products are widely used during the third trimester of

Evaluation of programs to improve complementary feeding in infants and young children.

PubMed

Frongillo, Edward A

2017-10-01

Evaluation of complementary feeding programs is needed to enhance knowledge on what works, to document responsible use of resources, and for advocacy. Evaluation is done during program conceptualization and design, implementation, and determination of effectiveness. This paper explains the role of evaluation in the advancement of complementary feeding programs, presenting concepts and methods and illustrating them through examples. Planning and investments for evaluations should occur from the beginning of the project life cycle. Essential to evaluation is articulation of a program theory on how change would occur and what program actions are required for change. Analysis of program impact pathways makes explicit the dynamic connections in the program theory and accounts for contextual factors that could influence program effectiveness. Evaluating implementation functioning is done through addressing questions about needs, coverage, provision, and utilization using information obtained from process evaluation, operations research, and monitoring. Evaluating effectiveness is done through assessing impact, efficiency, coverage, process, and causality. Plausibility designs ask whether the program seemed to have an effect above and beyond external influences, often using a nonrandomized control group and baseline and end line measures. Probability designs ask whether there was an effect using a randomized control group. Evaluations may not be able to use randomization, particularly for programs implemented at a large scale. Plausibility designs, innovative designs, or innovative combinations of designs sometimes are best able to provide useful information. Further work is needed to develop practical designs for evaluation of large-scale country programs on complementary feeding. © 2017 John Wiley & Sons Ltd.

The use of complementary and alternative medicine is high among children and youth with chronic illnesses, including patients with cardiac conditions. Our goal was to assess the prevalence and patterns of such use among patients presenting to academic pediatric cardiology clinics in Canada. A survey instrument was developed to inquire about current or previous use of complementary and alternative medicine products and practices, including indications, beliefs, sources of information and whether this use was discussed with physicians. Between February and July 2007, the survey was administered to patients (or their parents/guardians) presenting to 2 hospital-based cardiology clinics: the Stollery Children's Hospital in Edmonton, Alberta, and the Children's Hospital of Eastern Ontario in Ottawa, Ontario. At the Stollery Children's Hospital, 64.1% of the 145 respondents had used complementary and alternative medicine compared with 35.5% of the 31 respondents at the Children's Hospital of Eastern Ontario (p = 0.003). Overall, the most common products in current use were multivitamins (70.6%), vitamin C (22.1%), calcium (13.2%), unspecified "cold remedies" (11.8%) and fish oil or omega-3 fatty acids (11.8%). The most common practices in current use were massage (37.5%), faith healing (25.0%), chiropractic (20.0%), aromatherapy (15.0%) and Aboriginal healing (7.5%). Many patients (44.9%) used complementary and alternative medicine products at the same time as conventional prescription drugs. Concurrent use was discussed with physicians or pharmacists by 64.3% and 31.3% of respondents, respectively. Use of complementary and alternative medicine products and practices was high among patients seen in the pediatric cardiology clinics in our study. Most respondents believed that the use of these products and practices was helpful; few reported harms and many did not discuss this use with their physicians, increasing the potential for interactions with prescribed medications.

Complementary health insurance in France. Who pays? Why? Who will suffer from public disengagement?

PubMed

Saliba, Bérengère; Ventelou, Bruno

2007-05-01

The study is based on a rare database with information about health status, socioeconomic characteristics and the complementary health insurance choices of the French population. We intend to characterise a two-stage decision process: first, the decision to purchase complementary health insurance, and then the factors related to choice of policy quality. Our econometric study indicates that (i) income level has a strong and significant effect on the decision to purchase complementary insurance, whilst there is no evidence that health risk considerations affect this decision at all; (ii) the individual decision about quality is associated barely if at all with any rational explanatory variables. The population's concrete behaviour, revealed by the study, is consistent with an allocation of low-risk people to private insurance and high-risk people to public insurance. Complementary insurance is not especially relevant to patients with serious diseases, who depend much more on the public system. If the public insurance system were to disengage significantly from coverage of serious illness, a vacuum would be created that would leave people at high risk without full coverage. These results have broad implications for numerous national systems of social protection seeking a new mix between private and public insurance.

Humans as Sensors: Assessing the Information Value of Qualitative Farmer's Crop Condition Surveys for Crop Yield Monitoring and Forecasting

NASA Astrophysics Data System (ADS)

Beguería, S.

2017-12-01

While large efforts are devoted to developing crop status monitoring and yield forecasting systems trough the use of Earth observation data (mostly remotely sensed satellite imagery) and observational and modeled weather data, here we focus on the information value of qualitative data on crop status from direct observations made by humans. This kind of data has a high value as it reflects the expert opinion of individuals directly involved in the development of the crop. However, they have issues that prevent their direct use in crop monitoring and yield forecasting systems, such as their non-spatially explicit nature, or most importantly their qualitative nature. Indeed, while the human brain is good at categorizing the status of physical systems in terms of qualitative scales (`very good', `good', `fair', etcetera), it has difficulties in quantifying it in physical units. This has prevented the incorporation of this kind of data into systems that make extensive use of numerical information. Here we show an example of using qualitative crop condition data to estimate yields of the most important crops in the US early in the season. We use USDA weekly crop condition reports, which are based on a sample of thousands of reporters including mostly farmers and people in direct contact with them. These reporters provide subjective evaluations of crop conditions, in a scale including five levels ranging from `very poor' to `excellent'. The USDA report indicates, for each state, the proportion of reporters fort each condition level. We show how is it possible to model the underlying non-observed quantitative variable that reflects the crop status on each state, and how this model is consistent across states and years. Furthermore, we show how this information can be used to monitor the status of the crops and to produce yield forecasts early in the season. Finally, we discuss approaches for blending this information source with other, more classical earth data sources

We present a holographic implementation of accurate associative memory with only one holographic memory system. In the implementation, the stored and test images are coded by using complementary-encoding method. The recalled complete image is also a coded image that can be decoded with a decoding mask to get an original image or its complement image. The experiment shows that the complementary encoding can efficiently increase the addressing accuracy in a simple way. Instead of the above complementary-encoding method, a scheme that uses complementary area-encoding method is also proposed for the holographic implementation of gray-level image associative memory with accurate addressing.

Integrating complementary medicine and health care services into practice.

LaValley, J W; Verhoef, M J

1995-01-01

Complementary medicine and health care services constitute a significant proportion of the use of health care services in Canada, despite a history of limited acceptance of these therapies by the medical profession. However, physician attitudes appear to be changing. A survey of a random sample of general practitioners in Quebec (see page 29 of this issue) shows that four out of five general practitioners perceive at least one of three complementary health care services to be useful. Similar surveys of samples in Alberta and Ontario suggest that physicians there, although somewhat less enthusiastic than their counterparts in Quebec, have also begun to be more open-minded about these types of therapies. However, physicians have reported little understanding of complementary health care services, which suggests the need for more research on and education about these services. The Medical Society of Nova Scotia has responded to this need by establishing a Section of Complementary Medicine. The authors believe that fair, accountable, scientific and rigorous research on complementary therapies will benefit physicians and patients. The problems inherent in applying reductionist analysis to a holistic approach to care can be largely circumvented by focusing on outcomes research. In light of the popularity of these therapies, inquiry into patient use of complementary health care services should become a part of a complete patient history. This measure would promote greater patient-physician communication and integration of complementary health care services into patient care. PMID:7796375

Have complementary therapies demonstrated effectiveness in rheumatoid arthritis?

2016-01-01

In recent decades the treatment of rheumatoid arthritis (RA) has improved thanks to the use of highly effective drugs. However, patients usually require long term therapy, which is not free of side effects. Therefore RA patients often demand complementary medicine, they seek additional sources of relief and/or less side effects. In fact 30-60% of rheumatic patients use some form of complementary medicine. Therefore, from conventional medicine, if we want to optimally treat our patients facilitating communication with them we must know the most commonly used complementary medicines. The aim of this review is to assess, based on published scientific research, what complementary therapies commonly used by patients with RA are effective and safe.

A proper nutrition during the first two years of life is critical to reach the full potential of every human being; now, this period is recognized as a critical window for promoting optimal growth, development, and good health. Therefore, adequate feeding at this stage of life has an impact on health, nutritional status, growth and development of children; not only in the short term, but in the medium and long term. This paper provides recommendations on complementary feeding (CF) presented as questions or statements that are important for those who take care for children during this stage of life. For example: When to start complementary feedings: 4 or 6 months of age?; Exposure to potentially allergenic foods; Introduction of sweetened beverages; Use of artificial sweeteners and light products; Food introduction sequence; Food consistency changes according to neurological maturation; Number of days to test acceptance and tolerance to new foods; Amounts for each meal; Inadequate complementary feeding practices; Myths and realities of complementary feeding; Developmental milestones; Practice of "Baby Led Weaning" and practice of vegetarianism.

Regional crop yield forecasting: a probabilistic approach

NASA Astrophysics Data System (ADS)

de Wit, A.; van Diepen, K.; Boogaard, H.

2009-04-01

Information on the outlook on yield and production of crops over large regions is essential for government services dealing with import and export of food crops, for agencies with a role in food relief, for international organizations with a mandate in monitoring the world food production and trade, and for commodity traders. Process-based mechanistic crop models are an important tool for providing such information, because they can integrate the effect of crop management, weather and soil on crop growth. When properly integrated in a yield forecasting system, the aggregated model output can be used to predict crop yield and production at regional, national and continental scales. Nevertheless, given the scales at which these models operate, the results are subject to large uncertainties due to poorly known weather conditions and crop management. Current yield forecasting systems are generally deterministic in nature and provide no information about the uncertainty bounds on their output. To improve on this situation we present an ensemble-based approach where uncertainty bounds can be derived from the dispersion of results in the ensemble. The probabilistic information provided by this ensemble-based system can be used to quantify uncertainties (risk) on regional crop yield forecasts and can therefore be an important support to quantitative risk analysis in a decision making process.

Impact of maternal education about complementary feeding and provision of complementary foods on child growth in developing countries

PubMed Central

2011-01-01

Background Childhood undernutrition is prevalent in low and middle income countries. It is an important indirect cause of child mortality in these countries. According to an estimate, stunting (height for age Z score < -2) and wasting (weight for height Z score < -2) along with intrauterine growth restriction are responsible for about 2.1 million deaths worldwide in children < 5 years of age. This comprises 21 % of all deaths in this age group worldwide. The incidence of stunting is the highest in the first two years of life especially after six months of life when exclusive breastfeeding alone cannot fulfill the energy needs of a rapidly growing child. Complementary feeding for an infant refers to timely introduction of safe and nutritional foods in addition to breast-feeding (BF) i.e. clean and nutritionally rich additional foods introduced at about six months of infant age. Complementary feeding strategies encompass a wide variety of interventions designed to improve not only the quality and quantity of these foods but also improve the feeding behaviors. In this review, we evaluated the effectiveness of two most commonly applied strategies of complementary feeding i.e. timely provision of appropriate complementary foods (± nutritional counseling) and education to mothers about practices of complementary feeding on growth. Recommendations have been made for input to the Lives Saved Tool (LiST) model by following standardized guidelines developed by Child Health Epidemiology Reference Group (CHERG). Methods We conducted a systematic review of published randomized and quasi-randomized trials on PubMed, Cochrane Library and WHO regional databases. The included studies were abstracted and graded according to study design, limitations, intervention details and outcome effects. The primary outcomes were change in weight and height during the study period among children 6-24 months of age. We hypothesized that provision of complementary food and education of mother

2018-04-01

The widespread sale of complementary medicines in community pharmacy raises important questions regarding the responsibilities of pharmacists when selling complementary medicines. This study reviews the academic literature that explores a pharmacist's responsibilities when selling complementary medicines. International Pharmaceutical Abstracts, Embase, PubMed, Cinahl, PsycINFO and Philosopher's index databases were searched for articles written in English and published between 1995 and 2017. Empirical studies discussing pharmacists' practices or perceptions, consumers' expectations and normative studies discussing ethical perspectives or proposing ethical frameworks related to pharmacists' responsibilities in selling complementary medicines were included in the review. Fifty-eight studies met the inclusion criteria. The majority of the studies discussing the responsibilities of pharmacists selling complementary medicines had an empirical focus. Pharmacists and consumers identified counselling and ensuring safe use of complementary medicines as the primary responsibilities of pharmacists. No formal ethical framework is explicitly employed to describe the responsibilities of pharmacists selling complementary medicines. To the degree any ethical framework is employed, a number of papers implicitly rely on principlism. The studies discussing the ethical perspectives of selling complementary medicines mainly describe the ethical conflict between a pharmacist's business and health professional role. No attempt is made to provide guidance on appropriate ways to resolve the conflict. There is a lack of explicit normative advice in the existing literature regarding the responsibilities of pharmacists selling complementary medicines. This review identifies the need to develop a detailed practice-specific ethical framework to guide pharmacists regarding their responsibilities when selling complementary medicines. © 2018 Royal Pharmaceutical Society.

Background Complementary therapies are widespread but controversial. We aim to provide a comprehensive collection and a summary of systematic reviews of clinical trials in three major complementary therapies (acupuncture, herbal medicine, homeopathy). This article is dealing with homeopathy. Potentially relevant reviews were searched through the register of the Cochrane Complementary Medicine Field, the Cochrane Library, Medline, and bibliographies of articles and books. To be included articles had to review prospective clinical trials of homeopathy; had to describe review methods explicitly; had to be published; and had to focus on treatment effects. Information on conditions, interventions, methods, results and conclusions was extracted using a pretested form and summarized descriptively. Results Eighteen out of 22 potentially relevant reviews preselected in the screening process met the inclusion criteria. Six reviews addressed the question whether homeopathy is effective across conditions and interventions. The majority of available trials seem to report positive results but the evidence is not convincing. For isopathic nosodes for allergic conditions, oscillococcinum for influenza-like syndromes and galphimia for pollinosis the evidence is promising while in other areas reviewed the results are equivocal. Interpretation Reviews on homeopathy often address general questions. While the evidence is promising for some topics the findings of the available reviews are unlikely to end the controversy on this therapy. PMID:11527508

Complementary medicines (CMs) are popular amongst Australians and community pharmacy is a major supplier of these products. This study explores pharmacy customer use, attitudes and perceptions of complementary medicines, and their expectations of pharmacists as they relate to these products. Pharmacy customers randomly selected from sixty large and small, metropolitan and rural pharmacies in three Australian states completed an anonymous, self administered questionnaire that had been pre-tested and validated. 1,121 customers participated (response rate 62%). 72% had used CMs within the previous 12 months, 61% used prescription medicines daily and 43% had used both concomitantly. Multivitamins, fish oils, vitamin C, glucosamine and probiotics were the five most popular CMs. 72% of people using CMs rated their products as 'very effective' or 'effective enough'. CMs were as frequently used by customers aged 60 years or older as younger customers (69% vs. 72%) although the pattern of use shifted with older age. Most customers (92%) thought pharmacists should provide safety information about CMs, 90% thought they should routinely check for interactions, 87% thought they should recommend effective CMs, 78% thought CMs should be recorded in customer's medication profile and 58% thought pharmacies stocking CMs should also employ a complementary medicine practitioner. Of those using CMs, 93% thought it important for pharmacists to be knowledgeable about CMs and 48% felt their pharmacist provides useful information about CMs. CMs are widely used by pharmacy customers of all ages who want pharmacists to be more involved in providing advice about these products.

We studied cerebral effects of complementary acupuncture in Parkinson's disease using single photon emission computed tomography (SPECT) measures of 99mTc-ECD and 99mTc-TRODAT-4, before and after five weeks of treatment. Ten patients were randomly assigned to receive levodopa alone (controls) or levodopa and complementary scalp electro-acupuncture. Before treatment, no hemispheric regional cerebral blood flow (rCBF) differences were found, whereas striatal dopamine transporter (DAT) activity was lower in the most affected hemisphere. Treatment with levodopa alone did not change rCBF, whereas it increased basal ganglion DAT activity in the most affected hemisphere. Patients who received levodopa and complementary acupuncture had increased rCBF in the frontal lobe, the occipital lobe, the basal ganglion, and the cerebellum in the most affected hemisphere as compared to baseline, but there were no changes in basal ganglia DAT levels. Thus, complementary acupuncture treatment in Parkinson's disease may affect rCBF but not basal ganglion DAT.

Complementary and alternative medicine for allergic rhinitis.

Otolaryngologists and other physicians who diagnose and treat allergic rhinitis encounter patients who use complementary medicine and alternative remedies. This article reviews the recent literature regarding complementary and alternative therapies for the treatment of allergic rhinitis. There are a myriad of modalities for treating allergic rhinitis. Few are studied with rigorous randomized, double-blind, placebo-controlled trials for clinical efficacy. Often, the biological mechanisms and adverse effects are even less well understood. A few therapies, including spirulina, butterbur, and phototherapy hold some promise. Thus far, complementary and alternative therapies have not been integrated into the general treatment armamentarium of allergic rhinitis. Several studies report beneficial effects of certain alternative treatments for allergic rhinitis. Additional insight into the mechanisms of action, short-term and long-term effects, and adverse events is needed.

Complementary structure for designer localized surface plasmons

Gao, Zhen; Gao, Fei; Zhang, Youming; Zhang, Baile

2015-11-01

Magnetic localized surface plasmons (LSPs) supported on metallic structures corrugated by very long and curved grooves have been recently proposed and demonstrated on an extremely thin metallic spiral structure (MSS) in the microwave regime. However, the mode profile for the magnetic LSPs was demonstrated by measuring only the electric field, not the magnetic field. Here, based on Babinet's principle, we propose a Babinet-inverted, or complementary MSS whose electric/magnetic mode profiles match the magnetic/electric mode profiles of MSS. This complementarity of mode profiles allows mapping the magnetic field distribution of magnetic LSP mode profile on MSS by measuring the electric field distribution of the corresponding mode on complementary MSS. Experiment at microwave frequencies also demonstrate the use of complementary MSS in sensing refractive-index change in the environment.

The initiation of complementary feeding among Qom indigenous people.

PubMed

Olmedo, Sofia Irene; Valeggia, Claudia

2014-06-01

As of six months of life, breastfeeding no longer covers an infant's energy or micronutrient needs, so appropriate complementary feeding should be provided. The objective of this study was to assess the time and adequacy for introducing complementary feeding in a Qom/Toba population and analyze the sociocultural concepts of families regarding complementary feeding. Quantitative and qualitative data were collected by participant observation and semistructured surveys administered to mothers of 0-2 year old infants. Qom breastfeed their infants long term and on demand. Most infants have an adequate nutritional status and start complementary feeding at around 6 months old as per the local health center and international standards. However, mostly due to socioeconomic factors, foods chosen to complement breastfeeding have a relatively scarce nutritional value.

A calibration-free formulation of the complementary relationship of evaporation for continental-scale hydrology

NASA Astrophysics Data System (ADS)

Szilagyi, Jozsef; Crago, Richard; Qualls, Russell

2017-01-01

An important scaling consideration is introduced into the formulation of the complementary relationship (CR) of land surface evapotranspiration (ET) by specifying the maximum possible evaporation rate (Epmax) of a small water body (or wet patch) as a result of adiabatic drying from the prevailing near-neutral atmospheric conditions. In dimensionless form the CR therefore becomes yB = f(Epmax-EpEpmax-EwxB) = f(X) = 2X2 - X3, where yB = ET/Ep, xB = Ew/Ep. Ew is the wet-environment evaporation rate as given by the Priestley-Taylor equation, Ep is the evaporation rate of the same small wet surface for which Epmax is specified and estimated by the Penman equation. With the help of North American Regional Reanalysis data, the CR this way yields better continental-scale performance than earlier, calibrated versions of it and is on par with current land surface model results, the latter requiring vegetation, soil information and soil moisture bookkeeping. Validation has been performed by Parameter-Elevation Regressions on Independent Slopes Model precipitation and United States Geological Survey runoff data. A novel approach is also introduced to calculate the value of the Priestley-Taylor parameter to be used with continental-scale data, making the new formulation of the CR completely calibration free.

Results At the Stollery Children’s Hospital, 64.1% of the 145 respondents had used complementary and alternative medicine compared with 35.5% of the 31 respondents at the Children’s Hospital of Eastern Ontario (p = 0.003). Overall, the most common products in current use were multivitamins (70.6%), vitamin C (22.1%), calcium (13.2%), unspecified “cold remedies” (11.8%) and fish oil or omega-3 fatty acids (11.8%). The most common practices in current use were massage (37.5%), faith healing (25.0%), chiropractic (20.0%), aromatherapy (15.0%) and Aboriginal healing (7.5%). Many patients (44.9%) used complementary and alternative medicine products at the same time as conventional prescription drugs. Concurrent use was discussed with physicians or pharmacists by 64.3% and 31.3% of respondents, respectively. Interpretation Use of complementary and alternative medicine products and practices was high among patients seen in the pediatric cardiology clinics in our study. Most respondents believed that the use of these products and practices was helpful; few reported harms and many did not discuss this use with their physicians, increasing the

By exploiting the scaling invariance of photonic band diagrams, a complementary photonic crystal slab structure is realized by stacking two uniformly scaled double-zero-index dielectric photonic crystal slabs together. The space cancellation effect in complementary photonic crystals is demonstrated in both numerical simulations and microwave experiments. The refractive index dispersion of double-zero-index dielectric photonic crystal is experimentally measured. Using pure dielectrics, our photonic crystal structure will be an ideal platform to explore various intriguing properties related to a complementary medium.

The initiation of complementary feeding among Qom indigenous people

Irene Olmedo, Sofía; Valeggia, Claudia

2015-01-01

As of six months of life, breastfeeding no longer covers an infant’s energy or micronutrient needs, so appropriate complementary feeding should be provided. The objective of this study was to assess the time and adequacy for introducing complementary feeding in a Qom/Toba population and analyze the sociocultural concepts of families regarding complementary feeding. Quantitative and qualitative data were collected by participant observation and semistructured surveys administered to mothers of 0–2 year old infants. Qom breastfeed their infants long term and on demand. Most infants have an adequate nutritional status and start complementary feeding at around 6 months old as per the local health center and international standards. However, mostly due to socioeconomic factors, foods chosen to complement breastfeeding have a relatively scarce nutritional value. PMID:24862808

Although tonsillectomy is a common and largely safe procedure, pain management in children remains a controversial topic. In addition to the challenge of choosing appropriate analgesia, there is often low parent and child adherence. This article presents a review, and evaluates the potential role, of a range of complementary and alternative therapies that may be sought out by parents. A literature review of complementary and alternative interventions performed using PubMed, Cochrane Library, and EMBASE, supplemented by searches from Google and hand searches of cross-references of selected articles, yielded 32 studies for qualitative analysis. The studies included for analysis investigated a wide variety of alternative treatment modalities: acupuncture and related therapies, aromatherapy, homeopathy, honey, intravenous fluid, speech therapy, hyaluronic acid, behavioral therapies, ice/cold, hydrogen peroxide rinse, and chewing gum. At this time, stronger conclusions cannot be made about the therapies investigated because there are many methodology limitations of the studies analyzed. However, our results suggest merit for these treatments as adjuvant therapies that can enhance analgesia and decrease requirements of controversial medications. Honey and acupuncture have the greatest amount of evidence for postoperative pain and nausea; however, all interventions examined were cost-effective and safe. We recommend against hydrogen peroxide rinses and chewing gum. Laryngoscope, 2018. © 2018 The American Laryngological, Rhinological and Otological Society, Inc.

2014-01-01

The use of complementary and alternative medicine (CAM) as a source of cure has gained much spectrum worldwide, despite skeptics and advocates of evidence-based practice conceptualized such therapies as human nostrum. This study aimed to explore the factors affecting CAM use among rural communities in Malaysia. A cross-sectional study was carried out on 288 occupants across four rural villages within the District of Selama, Perak, Malaysia. A survey that consisted of socio-economic characteristics, history of CAM use and the validated Holistic Complementary and Alternative Medicine Questionnaire (HCAMQ) were used. The prevalence of self-reported CAM use over the past one year was 53.1%. Multiple logistic regression analyses yielded three significant predictors of CAM use: monthly household income of less than MYR 2500, higher education level, and positive attitude towards CAM. Psycho-socioeconomic factors were significantly associated with CAM use among rural communities in Malaysia.

Shape measurement of objects with large discontinuities and surface isolations using complementary grating projection

NASA Astrophysics Data System (ADS)

Hao, Yudong; Zhao, Yang; Li, Dacheng

1999-11-01

Grating projection 3D profilometry has three major problems that have to be handled with great care. They are local shadows, phase discontinuities and surface isolations. Carrying no information, shadow areas give us no clue about the profile there. Phase discontinuities often baffle phase unwrappers because they may be generated for several reasons difficult to distinguish. Spatial phase unwrapping will inevitably fail if the object under teste have surface isolations. In this paper, a complementary grating projection profilometry is reported, which attempts to tackle the three aforementioned problems simultaneously. This technique involves projecting two grating patterns form both sides of the CCD camera. Phase unwrapping is carried out pixel by pixel using the two phase maps based on the excess fraction method, which is immune to phase discontinuities or surface isolations. Complementary projection makes sure that no area in the visible volume of CCD is devoid of fringe information, although in some cases a small area of the reconstructed profile is of low accuracy compared with others. The system calibration procedures and measurement results are presented in detail, and possible improvement is discussed.

Modelling Pasture-based Automatic Milking System Herds: The Impact of Large Herd on Milk Yield and Economics.

Islam, M R; Clark, C E F; Garcia, S C; Kerrisk, K L

2015-07-01

The aim of this modelling study was to investigate the effect of large herd size (and land areas) on walking distances and milking interval (MI), and their impact on milk yield and economic penalties when 50% of the total diets were provided from home grown feed either as pasture or grazeable complementary forage rotation (CFR) in an automatic milking system (AMS). Twelve scenarios consisting of 3 AMS herds (400, 600, 800 cows), 2 levels of pasture utilisation (current AMS utilisation of 15.0 t dry matter [DM]/ha, termed as 'moderate'; optimum pasture utilisation of 19.7 t DM/ha, termed as 'high') and 2 rates of incorporation of grazeable complementary forage system (CFS: 0, 30%; CFS = 65% farm is CFR and 35% of farm is pasture) were investigated. Walking distances, energy loss due to walking, MI, reduction in milk yield and income loss were calculated for each treatment based on information available in the literature. With moderate pasture utilisation and 0% CFR, increasing the herd size from 400 to 800 cows resulted in an increase in total walking distances between the parlour and the paddock from 3.5 to 6.3 km. Consequently, MI increased from 15.2 to 16.4 h with increased herd size from 400 to 800 cows. High pasture utilisation (allowing for an increased stocking density) reduced the total walking distances up to 1 km, thus reduced the MI by up to 0.5 h compared to the moderate pasture, 800 cow herd combination. The high pasture utilisation combined with 30% of the farm in CFR in the farm reduced the total walking distances by up to 1.7 km and MI by up to 0.8 h compared to the moderate pasture and 800 cow herd combination. For moderate pasture utilisation, increasing the herd size from 400 to 800 cows resulted in more dramatic milk yield penalty as yield increasing from c.f. 2.6 and 5.1 kg/cow/d respectively, which incurred a loss of up to $AU 1.9/cow/d. Milk yield losses of 0.61 kg and 0.25 kg for every km increase in total walking distance (voluntary return

To define complementary and alternative medicine (CAM); describe one type of CAM, garlic (Allium sativum L); and discuss its effects on blood pressure as a treatment for hypertension. Literature review from professional journals, abstracts, natural therapy books, and the World Wide Web (Internet). Information from the following professional organizations and agencies: The World Health Organization, Agency of Healthcare Research and Quality, National Cancer Institute, National Center for Complementary and Alternative Medicine, American Botanical Council, and Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure. Garlic is widely used throughout the world as a CAM. It is one of the most popular herbal products sold in the United States. However, while some studies have shown small positive effects in reducing blood pressure, there are insufficient scientific data to draw conclusions regarding its efficacy on clinical blood pressure outcomes. Thus, healthcare providers should be cautious in recommending this herbal product as an antihypertensive CAM. CAMs may be used by clients for a variety of conditions including hypertension. Healthcare providers must be cognizant of the use, efficacy, adverse affects, and scientific evidence concerning CAM in order to provide safe and effective practice as well as appropriate and accurate information to their clients.

Self-complementary circular codes in coding theory.

Fimmel, Elena; Michel, Christian J; Starman, Martin; Strüngmann, Lutz

2018-04-01

Self-complementary circular codes are involved in pairing genetic processes. A maximal [Formula: see text] self-complementary circular code X of trinucleotides was identified in genes of bacteria, archaea, eukaryotes, plasmids and viruses (Michel in Life 7(20):1-16 2017, J Theor Biol 380:156-177, 2015; Arquès and Michel in J Theor Biol 182:45-58 1996). In this paper, self-complementary circular codes are investigated using the graph theory approach recently formulated in Fimmel et al. (Philos Trans R Soc A 374:20150058, 2016). A directed graph [Formula: see text] associated with any code X mirrors the properties of the code. In the present paper, we demonstrate a necessary condition for the self-complementarity of an arbitrary code X in terms of the graph theory. The same condition has been proven to be sufficient for codes which are circular and of large size [Formula: see text] trinucleotides, in particular for maximal circular codes ([Formula: see text] trinucleotides). For codes of small-size [Formula: see text] trinucleotides, some very rare counterexamples have been constructed. Furthermore, the length and the structure of the longest paths in the graphs associated with the self-complementary circular codes are investigated. It has been proven that the longest paths in such graphs determine the reading frame for the self-complementary circular codes. By applying this result, the reading frame in any arbitrary sequence of trinucleotides is retrieved after at most 15 nucleotides, i.e., 5 consecutive trinucleotides, from the circular code X identified in genes. Thus, an X motif of a length of at least 15 nucleotides in an arbitrary sequence of trinucleotides (not necessarily all of them belonging to X) uniquely defines the reading (correct) frame, an important criterion for analyzing the X motifs in genes in the future.

Golay Complementary Waveforms in Reed–Müller Sequences for Radar Detection of Nonzero Doppler Targets

PubMed Central

Wang, Xuezhi; Huang, Xiaotao; Suvorova, Sofia; Moran, Bill

2018-01-01

Golay complementary waveforms can, in theory, yield radar returns of high range resolution with essentially zero sidelobes. In practice, when deployed conventionally, while high signal-to-noise ratios can be achieved for static target detection, significant range sidelobes are generated by target returns of nonzero Doppler causing unreliable detection. We consider signal processing techniques using Golay complementary waveforms to improve radar detection performance in scenarios involving multiple nonzero Doppler targets. A signal processing procedure based on an existing, so called, Binomial Design algorithm that alters the transmission order of Golay complementary waveforms and weights the returns is proposed in an attempt to achieve an enhanced illumination performance. The procedure applies one of three proposed waveform transmission ordering algorithms, followed by a pointwise nonlinear processor combining the outputs of the Binomial Design algorithm and one of the ordering algorithms. The computational complexity of the Binomial Design algorithm and the three ordering algorithms are compared, and a statistical analysis of the performance of the pointwise nonlinear processing is given. Estimation of the areas in the Delay–Doppler map occupied by significant range sidelobes for given targets are also discussed. Numerical simulations for the comparison of the performances of the Binomial Design algorithm and the three ordering algorithms are presented for both fixed and randomized target locations. The simulation results demonstrate that the proposed signal processing procedure has a better detection performance in terms of lower sidelobes and higher Doppler resolution in the presence of multiple nonzero Doppler targets compared to existing methods.

Differential Attenuation of NMR Signals by Complementary Ion-Exchange Resin Beads for De Novo Analysis of Complex Metabolomics Mixtures.

PubMed

Zhang, Bo; Yuan, Jiaqi; Brüschweiler, Rafael

2017-07-12

A primary goal of metabolomics is the characterization of a potentially very large number of metabolites that are part of complex mixtures. Application to biofluids and tissue samples offers insights into biochemical metabolic pathways and their role in health and disease. 1D 1 H and 2D 13 C- 1 H HSQC NMR spectra are most commonly used for this purpose. They yield quantitative information about each proton of the mixture, but do not tell which protons belong to the same molecule. Interpretation requires the use of NMR spectral databases, which naturally limits these investigations to known metabolites. Here, a new method is presented that uses complementary ion exchange resin beads to differentially attenuate 2D NMR cross-peaks that belong to different metabolites. Based on their characteristic attenuation patterns, cross-peaks could be clustered and assigned to individual molecules, including unknown metabolites with multiple spin systems, as demonstrated for a metabolite model mixture and E. coli cell lysate. © 2017 Wiley-VCH Verlag GmbH & Co.

2018-06-01

Advances in autosomal DNA profiling systems enable analyzing increased numbers of short tandem repeat (STR) loci in one reaction. Increasing the number of STR loci increases the amount of information that may be obtained from a (crime scene) sample. In this study, we examined whether even more allelic information can be obtained by applying low-template methods. To this aim, the performance of the PowerPlex® Fusion 6C STR typing system was assessed when increasing the number of PCR cycles or enhancing the capillary electrophoresis (CE) injection settings. Results show that applying these low-template methods yields limited extra information and comes at cost of more background noise. In addition, the gain in detection of alleles was much smaller when compared to the gain when applying low-template methods to the 15-loci AmpFLSTR® NGM™ system. Consequently, the PowerPlex® Fusion 6C STR typing system was implemented using standard settings only; low-template methods were not implemented for our routine forensic casework.

2017-04-20

In order to utilize the spin field effect transistor in logic applications, the development of two types of complementary transistors, which play roles of the n- and p-type conventional charge transistors, is an essential prerequisite. In this research, we demonstrate complementary spin transistors consisting of two types of devices, namely parallel and antiparallel spin transistors using InAs based quantum well channels and exchange-biased ferromagnetic electrodes. In these spin transistors, the magnetization directions of the source and drain electrodes are parallel or antiparallel, respectively, depending on the exchange bias field direction. Using this scheme, we also realize a complementary logic operation purely with spin transistors controlled by the gate voltage, without any additional n- or p-channel transistor.

The patients initiate the use of complementary and alternative medicine and this often remains hidden from their primary care physician. To explore general practitioners' knowledge and attitude towards complementary and alternative medicine, and study the need and appropriate forms of education, as well as ask their opinion on integration of alternative medicine into mainstream medicine. A voluntary anonymous questionnaire was used on two conferences for general practitioners organized by the Family Medicine Department of Semmelweis University. Complementary and alternative medicine was defined by the definition of the Hungarian Academy of Sciences and certified modalities were all listed. 194 general practitioners answered the questionnaire (39.8% response rate). 14% of the responders had licence in at least one of the complementary and alternative therapies, 45% used complementary and alternative therapy in their family in case of illness. It was the opinion of the majority (91.8%) that it was necessary to be familiar with every method used by their patients, however, 82.5% claimed not to have enough knowledge in complementary medicine. Graduate and postgraduate education in the field was thought to be necessary by 86% of the responders; increased odds for commitment in personal education was found among female general practitioners, less than 20 years professional experience and personal experience of alternative medicine. These data suggest that general practitioners would like to know more about complementary and alternative medicine modalities used by their patients. They consider education of medical professionals necessary and a special group is willing to undergo further education in the field.

Predicting Great Lakes fish yields: tools and constraints

USGS Publications Warehouse

Lewis, C.A.; Schupp, D.H.; Taylor, W.W.; Collins, J.J.; Hatch, Richard W.

1987-01-01

Prediction of yield is a critical component of fisheries management. The development of sound yield prediction methodology and the application of the results of yield prediction are central to the evolution of strategies to achieve stated goals for Great Lakes fisheries and to the measurement of progress toward those goals. Despite general availability of species yield models, yield prediction for many Great Lakes fisheries has been poor due to the instability of the fish communities and the inadequacy of available data. A host of biological, institutional, and societal factors constrain both the development of sound predictions and their application to management. Improved predictive capability requires increased stability of Great Lakes fisheries through rehabilitation of well-integrated communities, improvement of data collection, data standardization and information-sharing mechanisms, and further development of the methodology for yield prediction. Most important is the creation of a better-informed public that will in turn establish the political will to do what is required.

Few studies have examined the use of complementary health practices (e.g., mind/body practices and dietary supplements) among African Americans, particularly those who identify as being spiritual and/or religious. Furthermore, research on the health and health behavior profiles of such complementary health users is scant. The purpose of this study was to explore the use of complementary health practices and their lifestyle and health indicator correlates in a large, church-based African American population. Cross-sectional analysis of 1467 African American adults drawn from a church-based cohort study. Participants reported use of complementary health practices, lifestyle behaviors (e.g., diet and smoking status), and health indicators (e.g., physical health and medical problems). Multiple logistic regressions were conducted to examine associations between lifestyle variables, health indicators, and use of complementary health practices. Outcomes included prevalence of mind/body practices (e.g., meditation and Reiki) and dietary supplements (multivitamins) along with health indicator and lifestyle correlates of use. Use of complementary health practices was high; 40% reported using any mind/body practice and 50% reported using dietary supplements. Poorer physical health was associated with use of mind/body practices, while likelihood of meeting fruit and vegetable recommendations was significantly associated with dietary supplement use. Complementary health practices were used heavily in a church-based sample of African American adults. Poorer physical health was associated with use of complementary health practices, yet users also displayed health conscious behaviors. Given the high engagement in complementary health practices, it may be prudent to consider adapting complementary health approaches for use in wellness interventions targeting African Americans in faith-based settings.

There is increasing interest in complementary and alternative medicine generally, and especially by those affected by chronic diseases, such as diabetes mellitus. We aimed to determine the prevalence and pattern of complementary and alternative medicine use among patients suffering from diabetes mellitus in Shiraz, southern Iran. Another objective was to explore associated factors for use of complementary and alternative medicine among patients with diabetes mellitus. A 19-item semi-structured questionnaire (open- and close-ended) was administered to 239 patients with diabetes mellitus in this cross-sectional study. It was carried out in two outpatient diabetes clinics affiliated with the Shiraz University of Medical Sciences, Shiraz, Iran. One hundred and eighty patients (75.3%) used at least one type of complementary and alternative medicine in the last year prior to the interview. Patients with diabetes mellitus who were living in a large family (≥5 members), not taking insulin, and believed that complementary and alternative medicine have synergistic effects with conventional medicine, were independently and significantly (P values: 0.02, 0.04, and 0.01, respectively) more likely to use complementary and alternative medicine. Most of the users (97.7%) reported use of herbal preparations, and 89.4% of users did not change their medication, neither in medication schedule nor its dosage. The use of complementary and alternative medicine, especially herbal remedies, is popular among diabetes patients in Shiraz, Iran. This use is associated with patients' family size, type of conventional medications and their view about concomitant use of complementary and conventional medicine.

A simple methodology for integrating single-walled carbon nanotubes (SWNTs) onto complementary metal oxide semiconductor (CMOS) circuitry is presented. The SWNTs were incorporated onto the CMOS chip as the feedback resistor of a two-stage Miller compensated operational amplifier utilizing dielectrophoretic assembly. The measured electrical properties from the integrated SWNTs yield ohmic behavior with a two-terminal resistance of approximately 37.5 kOmega and the measured small signal ac gain (-2) from the inverting amplifier confirmed successful integration of carbon nanotubes onto the CMOS circuitry. Furthermore, the temperature response of the SWNTs integrated onto CMOS circuitry has been measured and had a thermal coefficient of resistance (TCR) of -0.4% degrees C(-1). This methodology, demonstrated for the integration of SWNTs onto CMOS technology, is versatile, high yield and paves the way for the realization of novel miniature carbon-nanotube-based sensor systems.

Background Complementary and alternative medicine (CAM) use is widespread among cancer patients. Information on safety and efficacy of CAM therapies is needed for both patients and health care providers. Well-designed randomized clinical trials (RCTs) of CAM therapy interventions can inform both clinical research and practice. Objectives To review important issues that affect the design of RCTs for CAM interventions. Methods Using the methods component of the Consolidated Standards for Reporting Trials (CONSORT) as a guiding framework, and a National Cancer Institute-funded reflexology study as an exemplar, methodological issues related to participants, intervention, objectives, outcomes, sample size, randomization, blinding, and statistical methods were reviewed. Discussion Trials of CAM interventions designed and implemented according to appropriate methodological standards will facilitate the needed scientific rigor in CAM research. Interventions in CAM can be tested using proposed methodology, and the results of testing will inform nursing practice in providing safe and effective supportive care and improving the well-being of patients.

Although complementary feeding is a universal practice, the methods and manner in which it is practiced vary between cultures, individuals and socioeconomic classes. The period of complementary feeding is a critical time of transition in the life of an infant, and inappropriate complementary feeding practices, with their associated adverse health consequences, remain a significant global public health problem. Educational interventions are widely acknowledged as effective in promoting public health strategy, and those aimed at improving complementary feeding practices provide information about proper complementary feeding practices to caregivers of infants/children. It is therefore important to summarise evidence on the effectiveness of educational interventions to improve the complementary feeding practices of caregivers of infants. To assess the effectiveness of educational interventions for improving the complementary feeding (weaning) practices of primary caregivers of children of complementary feeding age, and related health and growth outcomes in infants. In November 2017, we searched CENTRAL, MEDLINE, Embase, 10 other databases and two trials registers. We also searched the reference lists of relevant studies and reviews to identify any additional studies. We did not limit the searches by date, language or publication status. Randomised controlled trials (RCTs), comparing educational interventions to no intervention, usual practice, or educational interventions provided in conjunction with another intervention, so long as the educational intervention was only available in the experimental group and the adjunctive intervention was available to the control group. Study participants included caregivers of infants aged 4 to 24 months undergoing complementary feeding.

Vitamin D toxicity of dietary origin in cats fed a natural complementary kitten food

PubMed Central

Crossley, Victoria J; Bovens, Catherine PV; Pineda, Carmen; Hibbert, Angie; Finch, Natalie C

2017-01-01

Case series summary This case series describes two young sibling cats and an additional unrelated cat, from two separate households, that developed hypercalcaemia associated with hypervitaminosis D. Excessive vitamin D concentrations were identified in a natural complementary tinned kitten food that was fed to all three cats as part of their diet. In one of the cases, there was clinical evidence of soft tissue mineralisation. The hypercalcaemia and soft tissue mineralisation resolved following withdrawal of the affected food and medical management of the hypercalcaemia. Relevance and novel information This case series demonstrates the importance of obtaining a thorough dietary history in patients presenting with hypercalcaemia and the measurement of vitamin D metabolites when investigating such cases. Complementary foods may have the potential to induce nutritional toxicity even when fed with complete, nutritionally balanced diets. PMID:29270305

Provision of clinically relevant information about complementary and alternative medicine (CAM) to health care professionals is not well described. The aim of the study was to assess questions about CAM to the Regional Medicines Information and Pharmacovigilance Centres in Norway (RELIS). All question-answers pairs (QAPs) in the RELIS database indexed with alternative medicine from 2005-2010 constituted the study material. A randomly selected sample of 100 QAPs was characterized with regard to type of question (category, patient-specific or general), occupation and workplace of enquirer, the type of information search performed (simple or advanced), and if the answers contained information to provide factual or consultative replies (facts about or advice on clinical use of CAM, respectively). Proportions were compared with Fisher's exact test with significance at the 0.05 level. One thousand and thirty-eight (7.7%) out of 13 482 questions involved CAM. Eighty-two out of 100 questions concerned products containing one or more herbs, vitamins and minerals as well as other substances. Thirty-eight out of 100 questions concerned the category documentation (substance identification and/or literature reports about clinical effects), 36 interactions, 16 adverse effects, 9 pregnancy and lactation, and 1 question concerned contraindications. Sixty-three questions were patient-specific and 37 general. Fifty-four questions came from physicians, 33 from pharmacists and 13 from others (including nurses, midwives, students, CAM practitioners, and the public). Pharmacists asked more frequently about interactions while physicians asked more frequently about adverse effects (p < 0.05). Seventy-six of the questions came from outside hospital, mainly general practice and community pharmacies. Fifty-nine answers were based on a simple and 41 on an advanced information search.

To determine the prevalence and profile of patients who use complementary and alternative medicine, within a cohort of head and neck cancer patients. Cross-sectional survey. Ninety-three consecutive head and neck cancer patients being followed up at the department of otolaryngology head and neck surgery were surveyed using an interviewer-administered questionnaire. The prevalence of complementary and alternative medicine use was 67.8 per cent. Patients who used complementary and alternative medicine were more likely to be female, better educated and younger, compared with non-users. A total of 82.5 per cent (52/63) perceived complementary and alternative medicine to be effective, even though they were aware of the lack of research and endorsement by their physician regarding such medicine. The use of complementary and alternative medicine by head and neck cancer patients is common, regardless of efficacy or cost. Clinicians should routinely ask patients about their use of complementary and alternative medicine, to facilitate communication and enable appropriate use of such medicine.

Integrating complementary therapies into health care education: a cautious approach.

PubMed

Richardson, J

2001-11-01

The movement of complementary therapy training and education into higher education in the United Kingdom (UK) and the interest in alternative therapeutic approaches within the health professions presents an ideal opportunity for multidisciplinary teaching and shared learning. The diversity and similarities of complementary therapies and areas of convergence with conventional healthcare practice can be explored. The recent publication of the House of Lords Select Committee on Science and Technology report on complementary and alternative medicine (HL Paper 123) provides a broader context for discussion and makes specific recommendations about regulation, education and research in the UK. This paper considers the appropriateness of integrating complementary therapies into education for conventional healthcare practitioners, what we should integrate, and when might be the most appropriate time in the education of healthcare practitioners to introduce different therapeutic modalities and their respective philosophical languages. Rather than present a range of solutions, the paper raises some fundamental issues that are central to the integration of complementary therapeutic approaches. If these issues are neglected as we hurry to incorporate different 'techniques' into our conventional practice, we may simply be left with additional tools that we are ill equipped to use.

Background Complementary therapies are widespread but controversial. We aim to provide a comprehensive collection and a summary of systematic reviews of clinical trials in three major complementary therapies (acupuncture, herbal medicine, homeopathy). This article is dealing with herbal medicine. Potentially relevant reviews were searched through the register of the Cochrane Complementary Medicine Field, the Cochrane Library, Medline, and bibliographies of articles and books. To be included articles had to review prospective clinical trials of herbal medicines; had to describe review methods explicitly; had to be published; and had to focus on treatment effects. Information on conditions, interventions, methods, results and conclusions was extracted using a pre-tested form and summarized descriptively. Results From a total of 79 potentially relevant reviews pre-selected in the screening process 58 met the inclusion criteria. Thirty of the reports reviewed ginkgo (for dementia, intermittent claudication, tinnitus, and macular degeneration), hypericum (for depression) or garlic preparations (for cardiovascular risk factors and lower limb atherosclerosis). The quality of primary studies was criticized in the majority of the reviews. Most reviews judged the available evidence as promising but definitive conclusions were rarely possible. Conclusions Systematic reviews are available on a broad range of herbal preparations prescribed for defined conditions. There is very little evidence on the effectiveness of herbalism as practised by specialist herbalists who combine herbs and use unconventional diagnosis. PMID:11518548

We aimed to evaluate the prevalence of and factors related to the use of complementary/alternative medicine among cancer patients undergoing or following conventional treatment at the Erciyes University Oncology Hospital in Central Anatolia. Face-to-face interview and a questionnaire were carried out with cancer patients attending the outpatient clinic of Medical Oncology. Questionnaire items included patients' demographic data, treatment, use of complementary/alternative medicine and possible related factors. Multivariate analysis was performed to compare the factors related to use of complementary/alternative medicine. A total of 268 consecutive cancer patients were enrolled in the study. Overall, 43% of the patients were using or had used complementary/alternative medicine. Totally, 90% of the patients using complementary/alternative medicine utilized herbs, and most of the herbs used were stinging nettle. Nearly half of the patients using complementary/alternative medicine (46.1%) were aiming to fight the disease. Among users, nearly half of them regarded the method used as effective and 54 (50.5%) suggested the use of complementary/alternative medicine to other patients. Only 23.1% of the patients discussed the use of complementary/alternative medicine with their physician. In logistic regression analysis, younger age, higher educational status, advanced stage of the disease, longer duration of the disease and current treatment status were significantly associated with the use of complementary/alternative medicine. In our regression model, the predictivity rate of these variables was 72.2% for use of complementary/alternative medicine according to the backward Wald test. Use of complementary/alternative medicine among cancer patients in our center is modestly high, and the most common method is herbal therapy. Communication between the patient and the physician should be improved on this subject.

The aim was to study the prevalence of complementary and alternative medicine use in acutely sick hospitalized children and factors associated with it. This is a cross-sectional, hospital-based study in a tertiary care center of Delhi, India. Children admitted to a pediatric unit during the study period were assessed using a specially designed questionnaire. Out of the total 887 admitted children, 161 (18.1%) were using complementary and alternate medicine in one form or another. Of these, 113 (70.2%) were using complementary and alternate medicine for the current illness directly leading to admission and the remaining 48 (29.8%) had used complementary and alternate medicine in past. The common complementary and alternate medicine use observed in our study was combined ayurveda and spiritual approach (25.5%), ayurveda (24.8%), spiritual (21.7%), homeopathic (13%), and 47.2% of children were using spiritual approach in form of Jhada (tying piece of cloth on arm or leg or keeping a knife by the side of child). The significant factors associated with complementary and alternate medicine use were younger age, female gender, and father being employed. Complementary and alternate medicine is commonly used even in acutely sick children. PMID:29616560

Factors Associated with the Early Introduction of Complementary Feeding in Saudi Arabia.

Mothers' instigation of complementary feeding before their infant reaches 6 months old risks shortening their breastfeeding duration, and high morbidity and mortality for their child. Complementary feeding practices require further investigation in Saudi Arabia. The present study aims to evaluate complementary feeding practices, and to establish which factors are associated with the early introduction of complementary feeding in the Saudi Arabian context. Cross-sectional research was conducted with 632 mothers of infants aged between 4 and 24 months attending five primary health care centers (PHCCs) between July and December 2015 in Saudi Arabia. Data on participants' socio-demographic characteristics and complementary feeding practices were collected via structured questionnaires. A regression analysis identified the factors associated with the early introduction of solid foods, defined as before 17 weeks. 62.5% of the study's infants received solid foods before reaching 17 weeks old. The maternal factors at higher risk of early introduction of solids were: younger age; Saudi nationality; shorter education; employment within 6 months post-birth; caesareans; not breastfeeding fully for six weeks post-birth, and living in low-income households. Complementary feeding prior to 6 months postpartum was common in Saudi Arabia. Public health interventions are needed to reduce early complementary feeding, focusing on mothers at highest risk of giving solids too early.

This position paper on complementary feeding summarizes evidence for health effects of complementary foods. It focuses on healthy infants in Europe. After reviewing current knowledge and practices, we have formulated these conclusions: Exclusive or full breast-feeding for about 6 months is a desirable goal. Complementary feeding (ie, solid foods and liquids other than breast milk or infant formula and follow-on formula) should not be introduced before 17 weeks and not later than 26 weeks. There is no convincing scientific evidence that avoidance or delayed introduction of potentially allergenic foods, such as fish and eggs, reduces allergies, either in infants considered at increased risk for the development of allergy or in those not considered to be at increased risk. During the complementary feeding period, >90% of the iron requirements of a breast-fed infant must be met by complementary foods, which should provide sufficient bioavailable iron. Cow's milk is a poor source of iron and should not be used as the main drink before 12 months, although small volumes may be added to complementary foods. It is prudent to avoid both early (<4 months) and late (>or=7 months) introduction of gluten, and to introduce gluten gradually while the infant is still breast-fed, inasmuch as this may reduce the risk of celiac disease, type 1 diabetes mellitus, and wheat allergy. Infants and young children receiving a vegetarian diet should receive a sufficient amount ( approximately 500 mL) of breast milk or formula and dairy products. Infants and young children should not be fed a vegan diet.

Non-conventional medical practices that make use of dietary supplements, herbal extracts, physical manipulations, and other practices typically associated with folk and Traditional Medicine are increasingly becoming popular in Western Countries. These practices are commonly referred to by the generic, all-inclusive term "Complementary and Alternative Medicine." Scientists, practitioners, and medical institutions bear the responsibility of testing and proving the effectiveness of these non-conventional medical practices in the interest of patients. In this context, the number of peer-reviewed journals and published articles on this topic has greatly increased in the recent decades. In this editorial article, we illustrate the policy of the Journal of Traditional and Complementary Medicine for publishing solid and scientifically sound papers in the field of Traditional and Complementary Medicine.

To investigate patients' attitudes toward complementary and alternative medicine, the education nurses provided about complementary and alternative medicine for treating depression and to test whether such education mediates the effect of complementary and alternative medicine use and attitudes toward complementary and alternative medicine. Although we know that attitudes influence behaviour, very few studies simultaneously explore the relationship between attitudes, education and complementary and alternative medicine use. Survey. This study was conducted as part of a larger survey, using face-to-face survey interviews with 206 adult patients aged 50 years or over and hospitalised in conventional hospitals in Taiwan for treatment of depression. The attitudes toward complementary and alternative medicine and patient education about complementary and alternative medicine instruments were specially developed for the study. Participants expressed slightly favourable attitudes toward complementary and alternative medicine. Many participants (50%) expressed that they were willing to try any potential treatment for depression. They believed that complementary and alternative medicine helped them to feel better and to live a happier life. However, 66.5% of participants reported that they had inadequate knowledge of complementary and alternative medicine. Participants with a higher monthly income, longer depression duration and religious beliefs hold more positive attitudes toward complementary and alternative medicine. Most participants were not satisfied with the education they received about complementary and alternative medicine. Patient education about complementary and alternative medicine was found to be a mediator for the use of complementary and alternative medicine. Patient education from nurses may predict patients' attitudes toward complementary and alternative medicine. Continuing nursing education is needed to enable nurses to respond knowledgeably to

A 24-year-old man was admitted due to acute hepatitis with unknown etiology. After his condition and laboratory data gradually improved with conservative therapy, he was discharged 1 month later. Two months after his discharge, however, liver dysfunction reappeared. After his mother accidentally revealed that he took complementary and alternative medicine, discontinuation of the therapy caused his condition to improve. Finally, he was diagnosed with a recurrent drug-induced liver injury associated with Japanese complementary and alternative medicine. It is important to take the medical history in detail and consider complementary and alternative medicine as a cause of liver disease. PMID:28100990

Moral injury represents an emerging clinical construct recognized as a source of morbidity in current and former military personnel. Finding effective ways to support those affected by moral injury remains a challenge for both biomedical and complementary and alternative medicine. This paper introduces the concept of moral injury and suggests two complementary and alternative medicine, pastoral care and mindfulness, which may prove useful in supporting military personnel thought to be dealing with moral injury. Research strategies for developing an evidence-base for applying these, and other, complementary and alternative medicine modalities to moral injury are discussed. Published by Elsevier Ltd.

Background To examine the accuracy and adequacy of lay media news stories about complementary and alternative medicines and therapies. Methodology/Principal Findings A descriptive analysis of news stories about complementary and alternative medicine (CAM) in the Australian media using a national medical news monitoring website, mediadoctor.org.au. Each story was rated against 10 criteria by two individuals. Consensus scores of 222 news articles reporting therapeutic claims about complementary medicines posted on mediadoctor.org.au between 1 January 2004 and 1 September 2007 were calculated. The overall rating score for 222 CAM articles was 50% (95% CI 47% to 53%). There was a statistically significant (F = 3.68, p = 0.006) difference in cumulative mean scores according to type of therapy: biologically based practices (54%, 95% CI 50% to 58%); manipulative body based practices (46%, 95% CI 39% to 54%), whole medical systems (45%, 95% CI 32% to 58%), mind body medicine (41%, 95% CI 31% to 50%) and energy medicine (33%, 95% CI 11% to 55%). There was a statistically significant difference in cumulative mean scores (F = 3.72, p = 0.0001) according to the clinical outcome of interest with stories about cancer treatments (62%, 95% CI 54% to 70%) scoring highest and stories about treatments for children's behavioural and mental health concerns scoring lowest (31%, 95% CI 19% to 43%). Significant differences were also found in scores between media outlets. Conclusions/Significance There is substantial variability in news reporting practices about CAM. Overall, although they may be improving, the scores remain generally low. It appears that much of the information the public receives about CAM is inaccurate or incomplete. PMID:18545688

Complementary and Alternative Medicine in the Treatment of Chronic Pelvic Pain in Women: What Is the Evidence?

PubMed

Paiva, Sara; Carneiro, Márcia Mendonça

2013-01-01

Chronic pelvic pain (CPP) is defined as pain of at least 6 months' duration that occurs in the lower abdomen or below the umbilicus and has resulted in functional or psychological disability or required intervention and treatment. Therapeutic interventions center around the treatment of CPP as a diagnosis in and of itself, and treatment of specific disorders that may be related to CPP. A multidisciplinary approach for diagnosis and treatment seems to be most effective for symptomatic relief. This paper reviews the evidence for such interventions as psychological treatments including the use of complementary and alternative medicine techniques for CPP in women. Unfortunately, finding the best evidence in this setting is difficult as only very few randomized controlled trials are available. A combination of treatments is usually required over time for the treatment of refractory CPP. The multifactorial nature of CPP needs to be discussed with the patient and a good rapport as well as a partnership needs to be developed to plan a management program with regular followup. Promotion of a multidisciplinary approach which includes complementary and alternative medicine techniques in managing CPP in women seems to yield the best results.

Uniform and Complementary Social Interaction: Distinct Pathways to Solidarity

We examine how different forms of co-action give rise to feelings of solidarity. We propose that (a) coordinated action elicits a sense of solidarity, and (b) the process through which such solidarity emerges differs for different forms of co-action. We suggest that whether solidarity within groups emerges from uniform action (e.g. synchronizing, as when people speak in unison) or from more complementary forms of action (e.g. alternating, when speaking in turns) has important consequences for the emergent position of individuals within the group. Uniform action relies on commonality, leaving little scope for individuality. In complementary action each individual makes a distinctive contribution to the group, thereby increasing a sense of personal value to the group, which should contribute to the emergence of solidarity. The predictions receive support from five studies, in which we study groups in laboratory and field settings. Results show that both complementary and uniform co-action increase a sense of solidarity compared to control conditions. However, in the complementary action condition, but not in the uniform action (or synchrony) condition, the effect on feelings of solidarity is mediated by a sense of personal value to the group.

Recent needs for more accurate fission product yields include covariance information to allow improved uncertainty estimations of the parameters used by design codes. The aim of this work is to investigate the possibility to generate more reliable and complete uncertainty information on independent mass fission yields. Mass yields covariances are estimated through a convolution between the multi-Gaussian empirical model based on Brosa's fission modes, which describe the pre-neutron mass yields, and the average prompt neutron multiplicity curve. The covariance generation task has been approached using the Bayesian generalized least squared method through the CONRAD code.

The article presents the complementary filter implementation, that is used for the estimation of the pitch angle, in Lua script language. Inertial sensors as accelerometer and gyroscope were used in the study. Methods of angles estimation using acceleration and angular velocity sensors were presented in the theoretical part of the article. The operating principle of complementary filter has been presented. The prototype of Butterworth's analogue filter and its digital equivalent have been designed. Practical implementation of the issue was performed with the use of PC and DISCOVERY evaluation board equipped with STM32F01 processor, L3GD20 gyroscope and LS303DLHC accelerometer. Measurement data was transmitted by UART serial interface, then processed with the use of Lua software and luaRS232 programming library. Practical implementation was divided into two stages. In the first part, measurement data has been recorded and then processed with help of a complementary filter. In the second step, coroutines mechanism was used to filter data in real time.

To evaluate the extent of complementary and alternative medicine use and perceived effectiveness in patients with lysosomal storage diseases. A 26-item survey was distributed to 495 patients with type 1 Gaucher, Fabry, and type B Niemann-Pick diseases who were seen at the Lysosomal Storage Disease Program at the Mount Sinai School of Medicine. Survey responses were entered into an access database and analyzed using descriptive statistics. Surveys were completed by 167 respondents with an overall response rate of 34%. Complementary and alternative medicines were used by 45% of patients with type 1 Gaucher disease, 41% of patients with Fabry disease, and 47% of patients with type B Niemann-Pick for symptoms related to their disease. Complementary and alternative medicines were used most frequently by adult females (55%), in patients who reported having one or more invasive procedures due to their disease, patients who use one or more conventional medical therapies, or those with depression and/or anxiety. Overall perceived effectiveness of complementary and alternative medicine supplements was low; however, complementary and alternative medicine therapies were perceived as effective. Complementary and alternative medicines are commonly used among patients with lysosomal storage diseases. Assessment of the effectiveness of these approaches in the lysosomal storage diseases is needed, and physicians should be aware of complementary and alternative medicine therapies used by patients to evaluate safety and possible drug interactions.

With increasing frequency, patients with cancer and their family members are turning to the Internet to educate themselves about their disease and treatment options, including complementary and alternative medicine (CAM) and supportive care. However, very little is known about how national leading cancer centers represent these therapies via their websites. Simulating the perspective of an information-seeking patient or family member, we performed a systematic analysis of the websites of 41 National Cancer Institute designated comprehensive cancer centers. Two researchers independently evaluated websites, recorded CAM information, and rated quality of the websites using a 4-item Likert scale (overall, information, presentation, and navigation) with Cronbach's alpha = 0.97. Rating was adequately correlated between the two raters (correlation coefficient 0.8). Of 41 centers, 12 (29%) did not have functional websites with regard to information related to CAM. The most common CAM approaches mentioned were: acupuncture (59%), meditation/nutrition/spiritual support/yoga (56% for each), massage therapy (54%), and music therapy (51%). Twenty-three (23; 56%) presented information on support groups, 19 (46%) on patient seminars, 18 (44%) on survivorship effort, and 17 (41%) on symptom management clinics. Twenty-nine (29) (71%) of these websites had a telephone number available, 22 (54%) mentioned at least one ongoing research opportunity, and 19 (46%) provided links to the National Center for Complementary and Alternative Medicine website. Median rating of the quality of websites was 50 of 100, with only 7 (17%) of centers receiving a composite score 80 (excellent) or better. While a growing number of leading cancer centers provide information about CAM and supportive oncology information for patients via their websites, the quality and ease of navigation of these sites remain highly variable. Effective development and redesign of many of the websites is needed to better

Complementary therapies in rehabilitation: stroke patients' narratives. Part 2.

To document the narratives of nursing staff and patients in a Thailand Rehabilitation Centre where complementary therapies are used and to discuss perceived progress of these stroke patients. Specific complementary therapies used at this Rehabilitation Centre include Thai massage and herbal therapies. Whilst there has been a small amount of quantitative research on stroke patients and complementary therapies there has been no qualitative research on the experience of stroke patients and the use of complementary therapies. Qualitative pilot study using narrative inquiry and discourse analysis framed by poststructural theory. Six stroke patients were interviewed about their involvement in complementary therapy practice and treatments and their experiences of these therapies in rehabilitation. This study represents a reflective mining of patients' stories and captures the main theme of changes in stroke patients' embodiment and a main discourse of attending to and enabling progress. Throughout the storylines there are many other discourses such as hope, desire, helplessness, despair, fear, motivation, gratefulness, gladness and fragility. Threaded throughout the stroke patients' stories of their rehabilitation there is a layering of discourses involving tensions and a longing to overcome their disability. There are twists and detours in their stories that show the complexity of the illness experience. Progress is not straightforward with a quick recovery. Many contexts or variables influence progress such as spatiality, temporality and people. What is offered here is the reality of the rehabilitation process for stroke patients. Through the use of narrative inquiry the contexts of people, spatiality (environment) and temporality (time) are an important part of rehabilitation process. © 2011 Blackwell Publishing Ltd.

Complementary and alternative medicine (CAM) products are increasingly used because they are perceived as natural, relatively low-cost and probably effective therapies for various diseases including cancer. We aimed to determine the quantity and major characteristics of recent herbal/alternative medicine trials registered in clinicaltrials. gov in patients with cancer. "Cancer AND (herbal OR complementary OR alternative)" key words were used to query clinicaltrials. gov (access date 17 April 2015). From the results, 163 trials which have been conducted in patients with the diagnosis of cancer were identified and included in this analysis. At the date of access, 72 trials were completed, 37 trials were still recruiting patients and 10 trials had been withdrawn. Most common cancer type was breast cancer. Eighty-eight percent of trials were interventional and 60% of trials were randomized. The rate of new trial submission were similar for 5-year periods after 2000. The majority of the trials were conducted in United States of America (55%) and People's Republic of China (11%). Nine and 4 of 37 recruiting trials were recorded as phase II and phase III, respectively. When browsing was restricted to "recruiting" and "interventional" studies, the ratio of herbal/complementary treatment trials to all chemotherapy trials was 1.8 %. CAM research in patients with cancer is currently limited, both in terms of quantity and quality. Until high quality scientific and clinical research establishes safety and efficacy of CAM practices, physicians should rigorously inform patients and the public on potential risks and caveats associated with CAM practices.

It is important to support women to exclusively breastfeed for 6 months and continue breastfeeding for 24 months and beyond. It is also necessary to provide the poor with access to affordable ways to improve the quality of complementary foods. Currently, many countries do not have the legal and policy environment necessary to support exclusive and continued breastfeeding. Legislative and policy changes are also necessary for introducing complementary food supplements, allowing them to be marketed to those who need them, and ensuring that marketing remains appropriate and in full compliance with the International Code of Marketing of Breastmilk Substitutes. This paper aims to illustrate the above with examples from Indonesia and to identify legislative requirements for supporting breastfeeding and enabling appropriate access to high-quality complementary food supplements for children 6-24 months of age. Requirements include improved information, training, monitoring and enforcement systems for the International Code of Marketing of Breastmilk Substitutes; implementation and monitoring of the Baby-Friendly Hospital Initiative; establishment of a registration category for complementary food supplements to enhance availability of high-quality, low-cost fortified products to help improve young child feeding; clear identification and marketing of these products as complementary food supplements for 6-24-month-olds so as to promote proper use and not interfere with breastfeeding. © 2011 Blackwell Publishing Ltd.

Complementary bowtie aperture for localizing and enhancing optical magnetic field

Zhou, Nan; Kinzel, Edward C.; Xu, Xianfan

2011-08-01

Nanoscale bowtie antenna and bowtie aperture antenna have been shown to generate strongly enhanced and localized electric fields below the diffraction limit in the optical frequency range. According to Babinet's principle, their complements will be efficient for concentrating and enhancing magnetic fields. In this Letter, we discuss the enhancement of magnetic field intensity of nanoscale complementary bowtie aperture as well as complementary bowtie aperture antenna, or diabolo nanoantenna. We show that the complementary bowtie antenna resonates at a smaller wavelength and thus is more suitable for applications near visible wavelengths. The near-field magnetic intensity can be further enhanced by the addition of groove structures that scatter surface plasmon.

Weather-based forecasts of California crop yields

2005-09-26

Crop yield forecasts provide useful information to a range of users. Yields for several crops in California are currently forecast based on field surveys and farmer interviews, while for many crops official forecasts do not exist. As broad-scale crop yields are largely dependent on weather, measurements from existing meteorological stations have the potential to provide a reliable, timely, and cost-effective means to anticipate crop yields. We developed weather-based models of state-wide yields for 12 major California crops (wine grapes, lettuce, almonds, strawberries, table grapes, hay, oranges, cotton, tomatoes, walnuts, avocados, and pistachios), and tested their accuracy using cross-validation over themore » 1980-2003 period. Many crops were forecast with high accuracy, as judged by the percent of yield variation explained by the forecast, the number of yields with correctly predicted direction of yield change, or the number of yields with correctly predicted extreme yields. The most successfully modeled crop was almonds, with 81% of yield variance captured by the forecast. Predictions for most crops relied on weather measurements well before harvest time, allowing for lead times that were longer than existing procedures in many cases.« less

How Complementary and Alternative Medicine Practitioners Use PubMed

PubMed Central

Quint-Rapoport, Mia

2007-01-01

Background PubMed is the largest bibliographic index in the life sciences. It is freely available online and is used by professionals and the public to learn more about medical research. While primarily intended to serve researchers, PubMed provides an array of tools and services that can help a wider readership in the location, comprehension, evaluation, and utilization of medical research. Objective This study sought to establish the potential contributions made by a range of PubMed tools and services to the use of the database by complementary and alternative medicine practitioners. Methods In this study, 10 chiropractors, 7 registered massage therapists, and a homeopath (N = 18), 11 with prior research training and 7 without, were taken through a 2-hour introductory session with PubMed. The 10 PubMed tools and services considered in this study can be divided into three functions: (1) information retrieval (Boolean Search, Limits, Related Articles, Author Links, MeSH), (2) information access (Publisher Link, LinkOut, Bookshelf ), and (3) information management (History, Send To, Email Alert). Participants were introduced to between six and 10 of these tools and services. The participants were asked to provide feedback on the value of each tool or service in terms of their information needs, which was ranked as positive, positive with emphasis, negative, or indifferent. Results The participants in this study expressed an interest in the three types of PubMed tools and services (information retrieval, access, and management), with less well-regarded tools including MeSH Database and Bookshelf. In terms of their comprehension of the research, the tools and services led the participants to reflect on their understanding as well as their critical reading and use of the research. There was universal support among the participants for greater access to complete articles, beyond the approximately 15% that are currently open access. The abstracts provided by PubMed were

Irregularly shaped bodies with at most partial in situ data are a particular challenge for shape reconstruction and mapping. We have created an inversion algorithm and software package for complementary data sources, with which it is possible to create shape and spin models with feature details even when only groundbased data are available. The procedure uses photometry, adaptive optics or other images, occultation timings, and interferometry as main data sources, and we are extending it to include range-Doppler radar and thermal infrared data as well. The data sources are described as generalized projections in various observable spaces [2], which allows their uniform handling with essentially the same techniques, making the addition of new data sources inexpensive in terms of computation time or software development. We present a generally applicable shape support that can be automatically used for all surface types, including strongly nonconvex or non-starlike shapes. New models of Kleopatra (from photometry, adaptive optics, and interferometry) and Hermione are examples of this approach. When using adaptive optics images, the main information from these is extracted from the limb and terminator contours that can be determined much more accurately than the image pixel brightnesses that inevitably contain large errors for most targets. We have shown that the contours yield a wealth of information independent of the scattering properties of the surface [3]. Their use also facilitates a very fast and robustly converging algorithm. An important concept in the inversion is the optimal weighting of the various data modes. We have developed a mathematicallly rigorous scheme for this purpose. The resulting maximum compatibility estimate [3], a multimodal generalization of the maximum likelihood estimate, ensures that the actual information content of each source is properly taken into account, and that the resolution scale of the ensuing model can be reliably estimated

The timing of introduction of complementary foods and later health.

PubMed

Agostoni, Carlo; Przyrembel, Hildegard

2013-01-01

Complementary food is needed when human milk (or infant formula) alone is no longer sufficient for nutritional reasons. The timing of introduction needs to be determined on an individual basis although 6 months of exclusive breastfeeding can be recommended for most healthy term infants. Solid foods are intended to 'complement' ongoing breastfeeding with those dietary items whose intake has become marginal or insufficient. Both breastfeeding and complementary feeding can have direct or later consequences on health. Possible short-term health effects concern growth velocity and infections while possible long-term effects may relate to obesity, cardiovascular disease, autoimmunity (celiac disease and type 1 diabetes) and atopic disorders. For most of these it is impossible on the basis of the available evidence to conclude on the age when risks related to the start of complementary feeding are lowest or highest, with the possible exception of infections and early growth velocity. For undesirable health consequences, whilst potential mechanisms are recognized, the evidence from mostly observational studies is insufficient and requires more and prospective research. While the 6-month goal is desirable, introduction of suitable complementary food after 4 completed months with ongoing breastfeeding can be considered without adverse health consequences for infants living in affluent countries. Even less evidence on the consequences of the timing of complementary food introduction is available for formula-fed infants. Copyright © 2013 S. Karger AG, Basel.

Complementary π-π interactions induce multicomponent coassembly into functional fibrils.

PubMed

Ryan, Derek M; Doran, Todd M; Nilsson, Bradley L

2011-09-06

Noncovalent self-assembled materials inspired by amyloid architectures are useful for biomedical applications ranging from regenerative medicine to drug delivery. The selective coassembly of complementary monomeric units to provide ordered multicomponent fibrils is a possible strategy for enhancing the sophistication of these noncovalent materials. Herein we report that complementary π-π interactions can be exploited to promote the coassembly of phenylalanine (Phe) derivatives that possess complementary aromatic side-chain functionality. Specifically, equimolar mixtures of Fmoc-Phe and Fmoc-F(5)-Phe, which possess side-chain groups with complementary quadrupole electronics, readily coassemble to form two-component fibrils and hydrogels under conditions where Fmoc-Phe alone fails to self-assemble. In addition, it was found that equimolar mixtures of Fmoc-Phe with monohalogenated (F, Cl, and Br) Fmoc-Phe derivatives also coassembled into two-component fibrils. These results collectively indicate that face-to-face quadrupole stacking between benzyl side-chain groups does not account for the molecular recognition between Phe and halogenated Phe derivatives that promote cofibrillization but that coassembly is mediated by more subtle π-π effects arising from the halogenation of the benzyl side chain. The use of complementary π-π interactions to promote the coassembly of two distinct monomeric units into ordered two-component fibrils dramatically expands the repertoire of noncovalent interactions that can be used in the development of sophisticated noncovalent materials. © 2011 American Chemical Society

The use of complementary and alternative medicine by children with autism and the association of its use with child comorbid symptoms and parental stress was studied in an ethnically diverse population, in a cross-sectional study with structured interviews. The sample included 50 families of children with autism and 50 families of children with other developmental disabilities, matched by age/gender. Interview included the Complementary and Alternative Medicine Questionnaire, Gastrointestinal Questionnaire, Children's Sleep Habits Questionnaire, Aberrant Behavior Checklist, and Parenting Stress Index. In this ethnically diverse sample, the use of complementary and alternative medicine was significantly higher for the autism group. In the autism group, use was significantly related to child's irritability, hyperactivity, food allergies, and parental stress; in the developmental disabilities group, there was no association with child comorbid symptoms or parental stress. The results contribute information to health care providers about families of children with autism who are more likely to use complementary and alternative medicine.

Cooperative advertising is an agreement between a manufacturer and a retailer to share advertising cost at the local level. Previous studies have not investigated cooperative advertising for complementary products and their main focus was only on one good. In this paper, we study a two-echelon supply chain consisting of one manufacturer and one retailer with two complementary goods. The demand of each good is influenced not only by its price but also by the price of the other product. We use two game theory approaches to model this problem; Stackelberg manufacturer and Stackelberg retailer.

[Obesity and complementary feeding time: a period at risk].

PubMed

Vidailhet, M

2010-12-01

Relation between rapid growth during the first months of life and secondary risk of excessive adiposity is well demonstrated. Many works have indicated a birth feeding effect on weight gain during the first year of life and a protective effect towards later childhood and adult obesity. However all these studies are observational and several works denied this protective effect. Concerning complementary feeding, 3 interventional, randomized, studies achieved between 4 and 6 months of age, showed a good regulation of caloric intake and no weight gain modification due to complementary foods. Most of others studies are observational and don't show any relation between time of introduction of complementary foods and later fat mass. However 3 recent studies indicate, respectively at 7, 10 and 42 years of age, an increased adiposity, suggesting the possibility of a programmed excessive fat gain induced by an early complementary foods introduction. Very few studies have evaluated, besides the time of weaning, the kind, quantity and caloric density of foods used as complements, whereas other recent studies show the importance of appetite differences since the first months of life and the importance of genetic influence on these variations. Others works have emphasized the possible role of an excessive protein intake during the first 2 years of life. So, it appears that it may be necessary to pay attention not only on the date, but also on the kind and quantity of complementary foods, particularly in infants at risk for obesity, because of parental obesity, rapid weight growth or an excessive appetite.

Complementary and alternative medicine is a broad field of health including all health care practices and methods; and their accompanying theories and beliefs. In the present study, we aimed to examine the frequency of complementary-alternative medicine use, and its relation with glomerular filtration rate and depression in patients with chronic kidney disease at predialysis stage. A total of 1053 predialysis patients; 518 female and 535 male, that were followed up with chronic kidney disease for at least 3 months were enrolled into the study. Demographic features, biochemical parameters and findings of physical examination were recorded. Their compliance to diet, and knowledge about disease were questioned. Beck depression inventory and questionnaire regarding to complementary-alternative medicine use were performed. The overall frequency of complementary-alternative medicine use was 40.3% . Total ratio of herbal products was 46%. Complementary-alternative medicine use was significantly more frequent in female or single patients, and patients that informed about chronic kidney disease or under strict diet (p:0.007, p:0.016, p:0.02, p:0.016; respectively). When glomerular filtration rate of participants were considered, complementary-alternative medicine use was similar in different stages of kidney disease. Depression was observed in 41.9% of patients and significantly frequent in patients with alternative method use (p:0.002). Depression score was higher as creatinine increases and glomerular filtration rate decreases (p:0.002; r: 0,093). We determined that complementary-alternative medicine use gradually increases at predialysis stage as glomerular filtration rate decreases and there is a strict relation between complementary-alternative medicine use and depression or female gender. Disorder related stressors may lead to seeking of alternative methods. This article is protected by copyright. All rights reserved.

Milk yield is an important trait in dairy industry; thus, information regarding this phenotype is essential to measure the productivity of a farm. Total milk yield in one lactation period was often predicted using information from samples collected within certain time intervals. The rate of change of milk production between two-time intervals is defined as persistency. This article aims to estimate the persistency of milk yield between lactation 1, 2 and 3 in Indonesian Friesian Holstein (IFH) cows. Data was collected from Limpakuwus stable, Baturraden Dairy Cattle Breeding Centre, Central Java Indonesia. Records were obtained from cows which started lactating on 2013 until the end of third lactation around the beginning of 2016. Milk yield from the first (L1), second (L2) and third (L3) lactations of 21 cows were recorded in kilograms. Samples were collected in 30 days basis interval started from the 10th day of lactation up to the 10th month. In this population, the cows first calving was around February – April 2013; while the second and third calving occurred all over the relevant year. The mean of milk yield for L1, L2 and L3 were 17.77±3.70, 16.09±5.17 and 13.73±4.02 Kg respectively. The peak of milk yields was achieved at the second month of the lactation for L1, L2 and L3. The persistency from the second to the tenth test days were 97, 93 and 94% for L1, L2 and L3, respectively. Milk yield persistency is representing ability of cow in maintain milk production after peak during lactation period. The more persistent shows better performance of dairy cattle as well as farm management. For that, persistency value could be used as valuable information in evaluating the management in Indonesian dairy farms.

The objective of this study was to assess complementary and alternative medicine use and its related factors among Iranian dermatology outpatients. In this cross-sectional study, a self-structured questionnaire was administered to 600 dermatology outpatients. Mann-Whitney U test, chi-square test, and binary logistic regression test were used. A total of 188 (31.3%) patients had used one of complementary and alternative medicine methods. The most frequent method used was herbal medicine (89.9%). The mean years of duration of the skin condition were significantly higher in complementary and alternative medicine users compared with nonusers (P = .037). Patients with acne and alopecia significantly used more complementary and alternative medicine (odds ratio: 2.48 and 3.19, respectively). There was a significant relationship between education and using complementary and alternative medicine (P < .001). Complementary and alternative medicine use is prevalent among our patients and we should think of ways of educating general population about complementary and alternative medicine methods and their potential risks and benefits and encourage our health care workers to communicate these materials with their patients.

2014-05-01

Complementary and alternative medicine (CAM) has an increasing presence in dermatology. Complementary therapies have been studied in many skin diseases, including atopic dermatitis and psoriasis. This study sought to assess oral CAM use in dermatology relative to medicine as a whole in the United States, using the National Ambulatory Medical Care Survey. Variables studied include patient demographic characteristics, diagnoses, and CAM documented at the visits. A brief literature review of the top 5 CAM treatments unique to dermatology visits was performed. Most CAM users in both dermatology and medicine as a whole were female and white and were insured with private insurance or Medicare. Fish oil, glucosamine, glucosamine chondroitin, and omega-3 were the most common complementary supplements used in both samples. CAM use in dermatology appears to be part of a larger trend in medicine. Knowledge of common complementary therapies can help dermatologists navigate this expanding field.

Hot flashes (HF) are a common distressing symptom in women with breast cancer (BC). Current pharmacologic options are moderately effective and are associated with bothersome side effects. Complementary and alternative medicine is commonly used by cancer patients. However, information on the association of hot flashes severity with such use and self-rated health is lacking. To examine the hot flashes severity in women with breast cancer and its association with complementary and alternative medicine use and self-rated health (SRH). Longitudinal multicenter study to assess information needs of cancer outpatients. Patients with a diagnosis of breast cancer who were scheduled to undergo chemotherapy and/or radiotherapy. Hot flashes severity (0 = not present and 10 = as bad as you can imagine), use of complementary and alternative medicine (yes/no), and self-rating of health (SRH) status post-treatment and six-months thereafter (1-5, higher score = better SRH). The majority of women with HF (mean age = 54.4 years) were Caucasian and married, with higher education, and 93% had received surgical treatment for BC. At the end of treatment, 79% women reported experiencing HF [mean severity = 5.87, standard deviation (SD) = 2.9]; significantly more severe HF were reported by younger women with poor SRH, poor performance status, and those reporting doing spiritual practices. At follow-up, 73% had HF (mean severity = 4.86, SD = 3.0), and more severe HF were reported by younger women with poor self-rated health who had undergone chemotherapy plus radiotherapy, used vitamins, and did not exercise. A high percentage of women experienced hot flashes at the end of treatment and at six-month follow-up. A significant association of hot flashes severity with spiritual practice, increased vitamin use, and reduced exercise emphasize the need for future studies to confirm the results. This can facilitate safe use of complementary and alternative medicine and favorable outcomes while

Segunda coa (autumn) maize yield in Panama currently suffers occasionally from high water stress at the end of the growing season, however under future climate conditions warmer temperatures accelerate crop maturation and elevated CO (sub 2) concentrations improve water retention. This combination reduces end-of-season water stresses and eventually leads to small mean yield gains according to median projections, although accelerated maturation reduces yields in seasons with low water stresses. Calibrations of cultivar traits, soil profile, and fertilizer amounts are most important for representing baseline yields, however sensitivity to all management factors is reduced in an assessment of future yield changes (most dramatically for fertilizers), suggesting that yield changes may be more generalizable than absolute yields. Uncertainty around General Circulation Model (GCM)s' projected changes in rainfall gain in importance throughout the century, with yield changes strongly correlated with growing season rainfall totals. Climate changes are expected to be obscured by the large inter-annual variations in Panamanian climate that will continue to be the dominant influence on seasonal maize yield into the coming decades. The relatively high (A2) and low (B1) emissions scenarios show little difference in their impact on future maize yields until the end of the century. Uncertainties related to the sensitivity of CERES-Maize to carbon dioxide concentrations have a substantial influence on projected changes, and remain a significant obstacle to climate change impacts assessment. Finally, an investigation into the potential of simple statistical yield emulators based upon key climate variables characterizes the

The study aimed to identify factors associated with the introduction of inappropriate complementary feeding in the first year of life in children living in municipalities (counties) with low socioeconomic statusl. This was a cross-sectional multicenter study in 1,567 children 12 to 59 months of age in 48 municipalities participating in the Brazil Without Poverty plan in the South of Brazil. A structured questionnaire was applied to the children's parents to obtain socio-demographic information and the age at which inappropriate complementary foods were introduced for the first time in complementary feeding. Prevalence of introduction of sugar before four months of age was 35.5% (n = 497; 95%CI: 33.1-38.0). The prevalence rates for the introduction of cookies/crackers, creamy yogurt, and jelly before six months of age were 20.4% (n = 287; 95%CI: 18.3-22.3), 24.8% (n = 349; 95%CI: 22.4-27.1), and 13.8% (n = 192; 95%CI: 12.0-15.7), respectively. Associations were identified between low maternal schooling (PR = 1.25; 95%CI: 1.03-1.51) and low monthly family income (PR = 1.22; CI95%: 1.01-1.48) and the introduction of inappropriate complementary feeding. The study identified the introduction of inappropriate complementary feeding in the first year of life among children in municipalities with high socioeconomic vulnerability in the South of Brazil, associated with low maternal schooling and low monthly family income.

Climatic or technological ceilings could cause yield stagnation. Thus, identifying the principal reasons for yield stagnation within the context of the local climate and socio-economic conditions are essential for informing regional agricultural policies. In this study, we identified the climatic and technological ceilings for seven rice-production regions in China based on yield gaps and on a yield trend pattern analysis for the period 1980-2010. The results indicate that 54.9% of the counties sampled experienced yield stagnation since the 1980. The potential yield ceilings in northern and eastern China decreased to a greater extent than in other regions due to the accompanying climate effects of increases in temperature and decreases in radiation. This may be associated with yield stagnation and halt occurring in approximately 49.8-57.0% of the sampled counties in these areas. South-western China exhibited a promising scope for yield improvement, showing the greatest yield gap (30.6%), whereas the yields were stagnant in 58.4% of the sampled counties. This finding suggests that efforts to overcome the technological ceiling must be given priority so that the available exploitable yield gap can be achieved. North-eastern China, however, represents a noteworthy exception. In the north-central area of this region, climate change has increased the yield potential ceiling, and this increase has been accompanied by the most rapid increase in actual yield: 1.02 ton ha(-1) per decade. Therefore, north-eastern China shows a great potential for rice production, which is favoured by the current climate conditions and available technology level. Additional environmentally friendly economic incentives might be considered in this region. © 2013 John Wiley & Sons Ltd.

Complementary and alternative medicine includes a diverse group of medical and healthcare systems, practices and products not considered part of conventional medicine. Although there is information on unconventional practices in oncological diseases, specific data regarding the use of complementary and alternative medicine by hematology patients is scarce. The aim of this study is to document the prevalence of this modality of unconventional therapy in patients with malignant and benign hematological diseases, particularly children with acute lymphoblastic leukemia. An observational study of adult patients and guardians of children with malignant or benign hematological diseases was carried out by applying a structured questionnaire detailing the use and results of the most prevalent complementary and alternative medicine practices. One hundred and twenty patients were included; 104 had malignant and 16 had benign hematological diseases. The use of complementary and alternative medicine was greater in benign diseases but the difference was not statistically significant (64.7% versus 41.7%; p-value = 0.08). Patients and guardians with high school or college educations used these alternative practices more than patients with less schooling (60.7% versus 54.7%; p-value = 0.032). The use of folk remedies was most prevalent followed by herbal preparations and spiritual healing. Sixty-four percent of patients that used these unconventional practices reported improvement in their symptoms and increased capacity to perform daily activities. No significant difference was documented between patients with malignant or benign hematological diseases using these alternative practices. The majority of complementary and alternative medicine users reported improvement of the disease or chemotherapy-related symptoms.

Complementary feeding: clinically relevant factors affecting timing and composition.

Krebs, Nancy F; Hambidge, K Michael

Exclusive breastfeeding for the first 6 mo of life followed by optimal complementary feeding are critical public health measures for reducing and preventing morbidity and mortality in young children. Clinical factors, such as birth weight, prematurity, and illness, that affect the iron and zinc requirements of younger infants are discussed. Maternal diet and nutritional status do not have a strong effect on the mineral content of human milk, but physiologic changes in milk and the infants' status determine the dependence of the infant on complementary foods in addition to human milk to meet iron and zinc requirements after 6 mo. The nature of zinc absorption, which is suitably characterized by saturation response modeling, dictates that plant-based diets, which are low in zinc, are associated with low absolute daily absorbed zinc, which is inadequate to meet requirements. Foods with a higher zinc content, such as meats, are much more likely to be sufficient to meet dietary requirements. Current plant-based complementary feeding patterns for older fully breastfed infants in both developed and developing countries pose a risk of zinc deficiency. The strong rationale for the potential benefits of providing meat as an early complementary food, and the examples of successful intervention programs, provide potent incentives to pursue broader implementation programs, with concurrent rigorous evaluation of both efficacy and effectiveness.

Why Current Statistics of Complementary Alternative Medicine Clinical Trials is Invalid.

PubMed

Pandolfi, Maurizio; Carreras, Giulia

2018-06-07

It is not sufficiently known that frequentist statistics cannot provide direct information on the probability that the research hypothesis tested is correct. The error resulting from this misunderstanding is compounded when the hypotheses under scrutiny have precarious scientific bases, which, generally, those of complementary alternative medicine (CAM) are. In such cases, it is mandatory to use inferential statistics, considering the prior probability that the hypothesis tested is true, such as the Bayesian statistics. The authors show that, under such circumstances, no real statistical significance can be achieved in CAM clinical trials. In this respect, CAM trials involving human material are also hardly defensible from an ethical viewpoint.

Niche complementarity is a commonly invoked mechanism underlying the positive relationship between biodiversity and ecosystem functioning, but little empirical evidence exists for complementarity among pollinator species. This study related differences in three functional traits of pollinating bees (flower height preference, daily time of flower visitation and within-flower behaviour) to the seed set of the obligate cross-pollinated pumpkin Cucurbita moschata Duch. ex Poir. across a land-use intensity gradient from tropical rainforest and agroforests to grassland in Indonesia. Bee richness and abundance changed with habitat variables and we used this natural variation to test whether complementary resource use by the diverse pollinator community enhanced final yield. We found that pollinator diversity, but not abundance, was positively related to seed set of pumpkins. Bees showed species-specific spatial and temporal variation in flower visitation traits and within-flower behaviour, allowing for classification into functional guilds. Diversity of functional groups explained even more of the variance in seed set (r2=45%) than did species richness (r2=32%) highlighting the role of functional complementarity. Even though we do not provide experimental, but rather correlative evidence, we can link spatial and temporal complementarity in highly diverse pollinator communities to pollination success in the field, leading to enhanced crop yield without any managed honeybees.

Abstract Background: Complementary and alternative medicine (CAM) has an increasing presence in dermatology. Complementary therapies have been studied in many skin diseases, including atopic dermatitis and psoriasis. Objectives: This study sought to assess oral CAM use in dermatology relative to medicine as a whole in the United States, using the National Ambulatory Medical Care Survey. Design: Variables studied include patient demographic characteristics, diagnoses, and CAM documented at the visits. A brief literature review of the top 5 CAM treatments unique to dermatology visits was performed. Results: Most CAM users in both dermatology and medicine as a whole were female and white and were insured with private insurance or Medicare. Fish oil, glucosamine, glucosamine chondroitin, and omega-3 were the most common complementary supplements used in both samples. Conclusions: CAM use in dermatology appears to be part of a larger trend in medicine. Knowledge of common complementary therapies can help dermatologists navigate this expanding field. PMID:24517329

Integrative and complementary therapies for patients with advanced cancer.

Marchand, Lucille

2014-07-01

In integrative medicine, well-being is emphasized, and in palliative care, quality of life (QOL) is a similar concept or goal. Both can occur despite advanced cancer. Integrative medicine serves to combine the best of alternative, complementary and conventional therapies to optimize well-being and QOL, whether or not a person is at the end of their life. When integrative medicine is combined with palliative care modalities, the toolbox to provide symptom control and well-being or QOL is increased or broadened. Palliative care and integrative medicine are best provided early in the trajectory of illness such as cancer, and increase in amount as the illness progresses toward end of life. In cancer care, symptoms of the cancer, as well as symptoms produced by cancer therapies, are addressed with conventional and integrative therapies. Goals of care change as the disease progresses, and a patient's unique situation creates a different balance of integrative and conventional therapies. Integrative therapies such as music, aromatherapy, and massage might appeal to more patients than more specific, less common integrative therapies that might be more expensive, or seem more unusual such as Ayurvedic medicine and energy modalities. Each person may be drawn to different integrative modalities depending on factors such as cultural traditions, beliefs, lifestyle, internet information, advice from family and friends, books, etc. This review focuses on how integrative and complementary modalities can be included in comprehensive palliative care for patients with advanced malignancies. Nutrition and movement, often neglected in conventional treatment strategies, will also be included in the larger context of integrative and palliative modalities. Both conventional and integrative modalities in palliative care help patients live with empowerment, hope, and well-being no matter how long their lives last.

Improving real-time inflow forecasting into hydropower reservoirs through a complementary modelling framework

Accuracy of reservoir inflow forecasts is instrumental for maximizing the value of water resources and benefits gained through hydropower generation. Improving hourly reservoir inflow forecasts over a 24 h lead time is considered within the day-ahead (Elspot) market of the Nordic exchange market. A complementary modelling framework presents an approach for improving real-time forecasting without needing to modify the pre-existing forecasting model, but instead formulating an independent additive or complementary model that captures the structure the existing operational model may be missing. We present here the application of this principle for issuing improved hourly inflow forecasts into hydropower reservoirs over extended lead times, and the parameter estimation procedure reformulated to deal with bias, persistence and heteroscedasticity. The procedure presented comprises an error model added on top of an unalterable constant parameter conceptual model. This procedure is applied in the 207 km2 Krinsvatn catchment in central Norway. The structure of the error model is established based on attributes of the residual time series from the conceptual model. Besides improving forecast skills of operational models, the approach estimates the uncertainty in the complementary model structure and produces probabilistic inflow forecasts that entrain suitable information for reducing uncertainty in the decision-making processes in hydropower systems operation. Deterministic and probabilistic evaluations revealed an overall significant improvement in forecast accuracy for lead times up to 17 h. Evaluation of the percentage of observations bracketed in the forecasted 95 % confidence interval indicated that the degree of success in containing 95 % of the observations varies across seasons and hydrologic years.

Complementary and alternative medicine on wikipedia: opportunities for improvement.

Wikipedia, a free and collaborative Internet encyclopedia, has become one of the most popular sources of free information on the Internet. However, there have been concerns over the quality of online health information, particularly that on complementary and alternative medicine (CAM). This exploratory study aimed to evaluate several page attributes of articles on CAM in the English Wikipedia. A total of 97 articles were analyzed and compared with eight articles of broad categories of therapies in conventional medicine using the Mann-Whitney U test. Based on the Wikipedia editorial assessment grading, 4% of the articles attained "good article" status, 34% required considerable editing, and 56% needed substantial improvements in their content. The median daily access of the articles over the previous 90 days was 372 (range: 7-4,214). The median word count was 1840 with a readability of grade 12.7 (range: 9.4-17.7). Medians of word count and citation density of the CAM articles were significantly lower than those in the articles of conventional medicine therapies. In conclusion, despite its limitations, the general public will continue to access health information on Wikipedia. There are opportunities for health professionals to contribute their knowledge and to improve the accuracy and completeness of the CAM articles on Wikipedia.

Literature indicates that complementary and alternative medicine is used by patients with auditory and vestibular symptoms. This study sought to determine the prevalence of complementary and alternative medicine uptake, and examine attitudes towards complementary and alternative medicine in clinicians working with audiovestibular disorder patients. The Holistic Complementary and Alternative Medicine Questionnaire and a devised questionnaire about recent and lifetime use of complementary and alternative medicine were used. Fifty-four individuals, including audiologists, ENT surgeons, nurses and rehabilitationists, completed the questionnaires (67 per cent response rate). Lifetime prevalence of complementary and alternative medicine uptake was 44 per cent, and 12-month prevalence was 22 per cent. Uptake was more common in females, but there was no significant difference in use when comparing age, seniority or profession. Attitudes towards complementary and alternative medicine were mildly adverse, but sizeable standard deviation indicates wide-ranging attitudes. Clinicians working with patients with audiovestibular disorders have a range of attitudes towards complementary and alternative medicine. Personal uptake of complementary and alternative medicine was lower than that of the general UK population, but remains sizeable.

Abstract Background: As evidence-based medicine (EBM) becomes a standard in health care, it is essential that practitioners of complementary and alternative medicine (CAM) become experts in searching and evaluating the research literature. In support of this goal, the National Institutes of Health (NIH) National Center for Complementary and Alternative Medicine (NCCAM) provided R25 funding to nine CAM colleges to develop individual programs focused on teaching EBM. An overarching goal of these research education grants has been to provide CAM faculty and students with the skills they need to apply a rigorous evidence-based perspective to their training and practice. Methods/Results: This paper reviews the competencies and teaching strategies developed and implemented to enhance research literacy at all nine R25-funded institutions. While each institution designed approaches suitable for its research culture, the guiding principles were similar: to develop evidence-informed skills and knowledge, thereby helping students and faculty to critically appraise evidence and then use that evidence to guide their clinical practice. Curriculum development and assessment included faculty-driven learning activities and longitudinal curricular initiatives to encourage skill reinforcement and evaluate progress. Conclusion: As the field of integrative medicine matures, the NIH-NCCAM research education grants provide essential training for future clinicians and clinician-researchers. Building this workforce will facilitate multidisciplinary collaborations that address the unique needs for research that informs integrative clinical practice. PMID:25380144

Adverse drug events are a major safety issue in ambulatory care. Improving medication self-management could reduce these adverse events. Researchers have developed medication applications for tethered personal health records (PHRs), but little has been reported about medication applications for interoperable PHRs. Our objective was to develop two complementary personal health applications on a common PHR platform: one to assist children with complex health needs (MyMediHealth), and one to assist older adults in care transitions (Colorado Care Tablet). The applications were developed using a user-centered design approach. The two applications shared a common PHR platform based on a service-oriented architecture. MyMediHealth employed Web and mobile phone user interfaces. Colorado Care Tablet employed a Web interface customized for a tablet PC. We created complementary medication management applications tailored to the needs of distinctly different user groups using common components. Challenges were addressed in multiple areas, including how to encode medication identities, how to incorporate knowledge bases for medication images and consumer health information, how to include supplementary dosing information, how to simplify user interfaces for older adults, and how to support mobile devices for children. These prototypes demonstrate the utility of abstracting PHR data and services (the PHR platform) from applications that can be tailored to meet the needs of diverse patients. Based on the challenges we faced, we provide recommendations on the structure of publicly available knowledge resources and the use of mobile messaging systems for PHR applications.

Development of a strategic model for integrating complementary medicines into professional pharmacy practice.

Traditional medicine (TM) and complementary medicine (CM) products have played an increasingly important role in the business of pharmacy for over two decades in a number of countries. With a focus on the quality use of all medicines including complementary medicines, there have been a number of initiatives to encourage the integration of TM/CM products into professional practice. Recent studies report that many of the barriers that prevent such integration remain. To explore the pharmacists' perspective regarding how barriers to the integration of TM/CM products into the professional practice of pharmacy could be resolved. Purposive sampling and snowballing were used to recruit 11 registered pharmacists who had worked in community pharmacy for a minimum of 6 months to participate in one of 3 focus groups. Focus group questions informed by previous studies, explored participants' perspectives on the actions required to support professional services related to TM/CM products. Pharmacists proposed that five key stakeholders (professional pharmacy organizations, universities, government, pharmacy owners, and pharmacists) enact 4 developments that require a collaborative effort ("education and training", "building the evidence base", "developing reliable and accessible information resources", and "workplace support for best practice"). Manufacturers of TM/CM products were not identified by pharmacists as collaborators in these developments. Collectively, the findings from this study support a strategic model to guide the integration of TM/CM products into the professional practice of pharmacy. Copyright © 2017 Elsevier Inc.

2018-02-01

In this paper, we have proposed a new online Wavelet Complementary velocity Estimator (WCE) over position and acceleration data gathered from an electro hydraulic servo shaking table. This is a batch estimator type that is based on the wavelet filter banks which extract the high and low resolution of data. The proposed complementary estimator combines these two resolutions of velocities which acquired from numerical differentiation and integration of the position and acceleration sensors by considering a fixed moving horizon window as input to wavelet filter. Because of using wavelet filters, it can be implemented in a parallel procedure. By this method the numerical velocity is estimated without having high noise of differentiators, integration drifting bias and with less delay which is suitable for active vibration control in high precision Mechatronics systems by Direct Velocity Feedback (DVF) methods. This method allows us to make velocity sensors with less mechanically moving parts which makes it suitable for fast miniature structures. We have compared this method with Kalman and Butterworth filters over stability, delay and benchmarked them by their long time velocity integration for getting back the initial position data.

There is evidence that the use of Complementary and Alternative Medicine by childbearing women is becoming increasingly popular in industrialised countries. The aim of this is paper is to review the research literature investigating the midwives' support for the use of these therapies. A search for relevant research published from 2000 to 2009 was undertaken using a range of databases and by examining relevant bibliographies. A total of thirteen studies were selected for inclusion in this review. The findings indicate that the use of Complementary and Alternative Medicine is widespread in midwifery practice. Common indications for use include; labour induction and augmentation, nausea and vomiting, relaxation, back pain, anaemia, mal-presentation, perineal discomfort, postnatal depression and lactation problems. The most popular therapies recommended by midwives are massage therapy, herbal medicines, relaxation techniques, nutritional supplements, aromatherapy, homeopathy and acupuncture. Midwives support the use Complementary and Alternative Medicine because they believe it is philosophically congruent; it provides safe alternatives to medical interventions; it supports the woman's autonomy, and; incorporating Complementary and Alternative Medicine can enhance their own professional autonomy. There is considerable support by midwives for the use of Complementary and Alternative Medicine by expectant women. Despite this enthusiasm, currently there are few educational opportunities and only limited research evidence regarding CAM use in midwifery practice. These shortfalls need to be addressed by the profession. Midwives are encouraged to have an open dialogue with childbearing women, to document use and to base any advice on the best available evidence. Copyright © 2010 Australian College of Midwives.

We assessed the role of the human mirror neuron system (MNS) in complementary actions using functional magnetic resonance imaging while participants prepared to execute imitative or complementary actions. The BOLD signal in the right inferior frontal gyrus and bilateral inferior parietal lobes was greater during preparation of complementary than during imitative actions, suggesting that the MNS may be essential in dynamically coupling action observation to action execution.

The risks associated with consumer magazines giving advice on complementary therapies.

Mantle, Fiona

The increased popularity of complementary and alternative medicine (CAM) has led to increased demand for information on it, giving rise to the concept of "new experts". However, there is concern about the quality and accuracy of this information, much of which is published in popular magazines and written by contributors with no medical qualifications. To examine the extent of CAM product advice in women's and health magazines, and the potential for adverse drug/herbal interaction. Fifteen women's magazines were examined over one month. A total of 150 articles were identified, of which 131 were written by non-medically qualified contributors, mainly journalists. Out of the 150, 95 discussed ingested herbs which had the potential for adverse interactions and are contraindicated for certain groups. The findings have legal and ethical implications. The re-evaluation of the journalists' code of conduct to reflect this development in journalism should be considered.

Appropriate complementary food is a must for optimum growth of infants and children. The food should be diverse and be given in sufficient quantities 2-4 times a day depending upon age. Poverty, food insecurity, and lack of awareness regarding the choice of nutritious food ingredients are deterrents to optimum complementary feeding. In Bangladesh, 77% of children do not receive appropriate complementary food and, hence, the high prevalence of childhood malnutrition. We developed ready-to-use complementary foods (RUCFs) using locally available food ingredients, rice/lentil and chickpea, which conform to standard specifications. These foods were found to be acceptable by children and their mothers compared to the Pushti packet, the cereal-based supplement used in the erstwhile National Nutrition Program of Bangladesh. In a cluster-randomized community-based trial in rural Bangladesh among more than 5,000 children, the efficacy of rice/lentil- and chickpea-based RUCFs was compared with another commonly used supplementary food called wheat-soy blend++ (WSB++) and a commercial product called Plumpy'doz. Deceleration in length for age was significantly lower (by 0.02-0.04/month) in the rice/lentil, Plumpy'doz, and chickpea groups compared to the control group at 18 months of age. Weight-for-length z-score decline was lower only in Plumpy'doz and chickpea groups. WSB++ was not different from the control group. In children who received chickpea RUCF or Plumpy'doz, the prevalence of stunting was 5-6% lower at 18 months. These foods can be used to prevent or treat malnutrition among children, particularly those from food-insecure households. © 2017 Nestec Ltd., Vevey/S. Karger AG, Basel.

The leadership team: complementary strengths or conflicting agendas?

Miles, Stephen A; Watkins, Michael D

Senior leadership teams whose members play complementary roles have been chronicled as far back as Homer's account of the Trojan War: Although King Agamemnon commanded the Greek army, Achilles, Odysseus, and Nestor each played a distinct role in defeating Troy. Today, complementary-leadership structures are common and, in some cases, even institutionalized. Think of a CEO concerned mainly with external issues and a COO who focuses internally. The authors describe four kinds of complementarity: task, expertise, cognitive, and role. The two top executives at the software company Adobe Systems, for example, represent the second kind. As CEO, Bruce Chizen draws on his sales and marketing knowledge, while COO Shantanu Narayen adds his engineering and product development expertise. Roberto Goizueta, formerly the CEO of Coca-Cola, and Douglas Ivester, his COO (who later became CEO), were famous examples of the fourth type: Goizueta, the diplomat, maintained good relations with external stakeholders; Ivester, the warrior, drove the company to defeat the competition. Bringing together two or more people with complementary strengths can compensate for the natural limitations of each. But with the benefits comes the risk of confusion, disagreement about priorities, and turf battles. Leadership succession also presents substantial challenges, especially when a COO or president who has worked in a complementary fashion with the CEO moves into the top role. An organization's board of directors and CEO can manage the risks by fostering a shared vision, common incentives, communication, and trust. They can also ensure smooth succession processes in various ways, such as brokering a gradual transfer of responsibilities or allowing the CEO and the COO to share duties as long as they maintain the logic of complementarity.

The JEFF library does not contain fission yield covariances, but simply best estimates and uncertainties. This situation is not unique as all libraries are facing this deficiency, firstly due to the lack of a defined format. An alternative approach is to provide a set of random fission yields, themselves reflecting covariance information. In this work, these random files are obtained combining the information from the JEFF library (fission yields and uncertainties) and the theoretical knowledge from the GEF code. Examples of this method are presented for the main actinides together with their impacts on simple burn-up and decay heat calculations.

Complementary, alternative, integrative, or unconventional medicine?

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded the Kenneth B. Schwartz Center. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient, support to caregivers, and sustenance to the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. Interest in complementary and alternative medicine (CAM) has grown exponentially in the past decade, fueled by Internet marketing, dissatisfaction with mainstream medicine, and a desire for patients to be actively involved in their health care. There is a large discordance between physician estimates and reported prevalence of CAM use. Many patients do not disclose their practices mainly because they believe CAM falls outside the rubric of conventional medicine or because physicians do not ask. Concern about drug interactions and adverse effects are compounded by a lack of Food and Drug Administration regulation. Physicians need to be informed about CAM and be attuned to the psychosocial needs of patients.

Background The aim of this study was to determine the status of utilizing some complementary and alternative medicine techniques in infertile couples. Methods This was a cross-sectional study conducted on 250 infertile couples referred to a hospital in Kerman using convenience sampling. A researcher-made questionnaire was used to study the prevalence and user satisfaction of complementary and alternative medicines. Results Results indicated that 49.6% of the infertile couples used at least one of the complementary and alternative medicines during the past year. Most individuals used spiritual techniques (71.8% used praying and 70.2% used Nazr) and medicinal plants (54.8%). Safety is the most important factor affecting the satisfaction of infertile couples with complementary treatments (couples think that such treatments are safe (54.8%)). Discussion Concerning high prevalence of complementary and alternative treatments in infertile couples, incorporating such treatments into the healthcare education and promoting the awareness of infertile individuals seem crucial.

Timing of introduction of complementary food: short- and long-term health consequences.

PubMed

Przyrembel, Hildegard

2012-01-01

Complementary food is needed when breast milk (or infant formula) alone is no longer sufficient for both nutritional and developmental reasons. The timing of its introduction, therefore, is an individual decision, although 6 months of exclusive breastfeeding can be recommended for most healthy term infants. The new foods are intended to 'complement' ongoing breastfeeding with those dietary items whose intake has become marginal or insufficient. Both breastfeeding and complementary feeding can have direct or later consequences on health. The evaluation of consequences of both early and late introduction of complementary food can neither disregard the effect of breastfeeding compared to formula feeding nor the composition or quality of the complementary food. Possible short-term health effects concern growth velocity and infections, and possible long-term effects may relate to atopic diseases, type 1 and 2 diabetes, obesity and neuromuscular development. On the basis of the currently available evidence, it is impossible to exactly determine the age when risks related to the start of complementary feeding are lowest or highest for most of these effects, with the possible exception of infections and early growth velocity. The present knowledge on undesirable health effects, however, is mainly based on observational studies, and although some mechanisms have been proposed, further prospective studies have to clarify these unsolved issues. Even less evidence on the consequences of the timing of complementary food introduction is available for formula-fed infants. Copyright © 2012 S. Karger AG, Basel.

This study investigated complementary feeding practices among four ethnic groups (Han, Uygur, Tibetan, and Zhuang) based on a cross-sectional survey in rural western China. In 2005, a stratified multistage cluster random sampling method was used to recruit 9712 children (7411 Han, 1032 Uygur, 678 Tibetan, and 591 Zhuang) between 6 and 35 months of age and their mothers from 45 counties in 10 provinces (autonomous regions, municipalities) in western China. The rates of early introduction (before 6 months) of complementary foods in four ethnic groups (Han, Uygur, Tibetan, and Zhuang) were 71.30%, 95.95%, 82.40%, and 72.30%, respectively. The Infant and Child Feeding Index (ICFI) for Uygur and Tibetan children was lower than that for Han children at all age groups. Uygur children were more likely to have unqualified ICFI compared with Han children in a multivariate logistic regression (odds ratio (OR)=5.138, 95% confidence interval (CI): 4.340-6.084). A higher level of maternal education, greater family wealth, and the availability of complementary feeding educational materials decreased the likelihood of an unqualified ICFI. The nutritional status of children (Han, Tibetan, and Zhuang) with qualified ICFI was better than that for children with unqualified ICFI. Appropriate interventions are required to improve complementary feeding practices in rural western China.

Background Complementary and alternative medicine includes a diverse group of medical and healthcare systems, practices and products not considered part of conventional medicine. Although there is information on unconventional practices in oncological diseases, specific data regarding the use of complementary and alternative medicine by hematology patients is scarce. Objective The aim of this study is to document the prevalence of this modality of unconventional therapy in patients with malignant and benign hematological diseases, particularly children with acute lymphoblastic leukemia. Methods An observational study of adult patients and guardians of children with malignant or benign hematological diseases was carried out by applying a structured questionnaire detailing the use and results of the most prevalent complementary and alternative medicine practices. Results One hundred and twenty patients were included; 104 had malignant and 16 had benign hematological diseases. The use of complementary and alternative medicine was greater in benign diseases but the difference was not statistically significant (64.7% versus 41.7%; p-value = 0.08). Patients and guardians with high school or college educations used these alternative practices more than patients with less schooling (60.7% versus 54.7%; p-value = 0.032). The use of folk remedies was most prevalent followed by herbal preparations and spiritual healing. Sixty-four percent of patients that used these unconventional practices reported improvement in their symptoms and increased capacity to perform daily activities. Conclusion No significant difference was documented between patients with malignant or benign hematological diseases using these alternative practices. The majority of complementary and alternative medicine users reported improvement of the disease or chemotherapy-related symptoms. PMID:23049401

Many women would like to avoid pharmacological or invasive methods of pain management in labour and this may contribute towards the popularity of complementary methods of pain management. This review examined currently available evidence supporting the use of alternative and complementary therapies for pain management in labour. To examine the effectiveness of complementary and alternative therapies for pain management in labour on maternal and perinatal morbidity. We searched the Cochrane Pregnancy and Childbirth Group trials register (July 2002), the Cochrane Controlled Trials Register (The Cochrane Library Issue 2, 2002), MEDLINE (1966 to July 2002), EMBASE (1980 to July 2002) and CINAHL (1980 to July 2002). The inclusion criteria included published and unpublished randomised controlled trials comparing complementary and alternative therapies with placebo, no treatment or pharmacological forms of pain management in labour. All women whether primiparous or multiparous, and in spontaneous or induced labour, in the first and second stage of labour were included. Meta-analysis was performed using relative risks for dichotomous outcomes and weighted mean differences for continuous outcomes. The outcome measures were maternal satisfaction, use of pharmacological pain relief and maternal and neonatal adverse outcomes. Seven trials involving 366 women and using different modalities of pain management were included in this review. The trials included one involving acupuncture (n = 100), one involving audio-analgesia (n = 25), one involving aromatherapy (n = 22), three trials of hypnosis (n = 189) and one trial of music (n = 30). The trial of acupuncture decreased the need for pain relief (relative risk (RR) 0.56, 95% confidence interval (CI) 0.39 to 0.81). Women receiving hypnosis were more satisfied with their pain management in labour compared with controls (RR 2.33, 95% CI 1.55 to 4.71). No differences were seen for women receiving aromatherapy, music or audio

We compared abundance, species richness, and capture efficiency with pitfall traps and mini-Winkler extractors to examine their use as complementary methods for sampling soil Coleoptera during dry (2010) and high water seasons (2011) in three areas, including inundated and non-inundated regions, in the Pantanal of Poconé, Mato Grosso, Brazil. We paired treatments with two 10 × 10 m plots in inundated and non-inundated locations that were repeated three times in each location for a total of 18 plots. In each plot, we used nine pitfall traps and collected 2 m(2) of leaf litter and surface soil samples with mini-Winkler extractors. We collected a total of 4260 adult beetles comprising 36 families, 113 genera, and 505 species. Most were caught in pitfalls (69%) and the remainder in the mini-Winkler extractors (31%). Each method provided distinct information about the beetle community: 252 species were captured only in pitfall traps, 147 using only the mini-Winkler extractors, and these methods shared another 106 species. Pitfall and mini-Winkler contribute in different ways for the sampling of the soil beetle community, and so they should be considered complementary for a more thorough assessment of community diversity.

We report a simple, bottom-up/top-down approach for integrating drastically different nanoscale building blocks to form a heterogeneous complementary inverter circuit based on layered molybdenum disulfide and carbon nanotube (CNT) bundles. The fabricated CNT/MoS(2) inverter is composed of n-type molybdenum disulfide (MOS(2)) and p-type CNT transistors, with a high voltage gain of 1.3. The CNT channels are fabricated using directed assembly while the layered molybdenum disulfide channels are fabricated by mechanical exfoliation. This bottom-up fabrication approach for integrating various nanoscale elements with unique characteristics provides an alternative cost-effective methodology to complementary metal-oxide-semiconductors, laying the foundation for the realization of high performance logic circuits.

Transition metal dichalcogenides are of interest for next generation switches, but the lack of low resistance electron and hole contacts in the same material has hindered the development of complementary field-effect transistors and circuits. We demonstrate an air-stable, reconfigurable, complementary monolayer MoTe 2 field-effect transistor encapsulated in hexagonal boron nitride, using electrostatically doped contacts. The introduction of a multigate design with prepatterned bottom contacts allows us to independently achieve low contact resistance and threshold voltage tuning, while also decoupling the Schottky contacts and channel gating. We illustrate a complementary inverter and a p-i-n diode as potential applications.

Climate-Driven Crop Yield and Yield Variability and Climate Change Impacts on the U.S. Great Plains Agricultural Production.

PubMed

Kukal, Meetpal S; Irmak, Suat

2018-02-22

Climate variability and trends affect global crop yields and are characterized as highly dependent on location, crop type, and irrigation. U.S. Great Plains, due to its significance in national food production, evident climate variability, and extensive irrigation is an ideal region of investigation for climate impacts on food production. This paper evaluates climate impacts on maize, sorghum, and soybean yields and effect of irrigation for individual counties in this region by employing extensive crop yield and climate datasets from 1968-2013. Variability in crop yields was a quarter of the regional average yields, with a quarter of this variability explained by climate variability, and temperature and precipitation explained these in singularity or combination at different locations. Observed temperature trend was beneficial for maize yields, but detrimental for sorghum and soybean yields, whereas observed precipitation trend was beneficial for all three crops. Irrigated yields demonstrated increased robustness and an effective mitigation strategy against climate impacts than their non-irrigated counterparts by a considerable fraction. The information, data, and maps provided can serve as an assessment guide for planners, managers, and policy- and decision makers to prioritize agricultural resilience efforts and resource allocation or re-allocation in the regions that exhibit risk from climate variability.

Several studies have been done on infant feeding practices but few have focused on twins. The aim of this study was to compare the complementary feeding practices between mothers with twins and mothers with singletons. Mother-infant pairs (50 mother-twin pairs and 50 mother-singleton pairs) with children aged 6 to 23 months were recruited from two public health clinics and communities in Tema and Ashaiman. Information was collected on the background characteristics of the mothers. Recumbent length and weight of the children were measured. Dietary information on the infants was collected using 24 hour recall. The differences between two groups were tested using independent t-student test for continuous variables and chi-square test for categorical variables. The minimum dietary diversity (4+ food groups) was met by only 32% of the twins and 40% of the singletons, and 28% of the twins and 38% of the singletons met the requirement for minimum acceptable diet (minimum dietary diversity and the minimum meal frequency). Minimum meal frequency was met by 78% of the twins and 76% of the singletons. There were no significant differences between the two groups of infants. Prevalence of undernutrition was not significantly different among the two groups (twins versus singletons: underweight-26% versus 24%, stunting-20% versus 24% and wasting-14% versus 10%. Complementary feeding practices were suboptimal in both groups of mothers requiring interventions to improve infant feeding practices.

Linear Optical and SERS Study on Metallic Membranes with Subwavelength Complementary Patterns

An efficient technique is developed to fabricate optically thin metallic films with subwavelength patterns and their complements simultaneously. By comparing the spectra of the complementary films, we show that Babinet's principle nearly holds in the optical domain. A discrete-dipole approximation can qualitatively describe their spectral dependence on the geometry of the constituent particles and the illuminating polarization. Using pyridine as probe molecules, we studied surface-enhanced Raman spectroscopy (SERS) from the complementary structure. Although the complementary structure posses closely related linear spectra, they have quite different near-field behaviors. For hole arrays, their averaged local field gains as well as the SERS enhancements are strongly correlated to their transmission spectra. We therefore can use cos 4 θ to approximately describe the dependence of the Raman intensity on the excitation polarization angle θ , while the complementary particle arrays present maximal local field gains at wavelengths generally much bigger than their localized surface plasmonic resonant wavelengths.

The aim of this study is to understand the current tradition and complementary medicine (T&CM) education in Malaysia. We referred to literature regarding to traditional medicine education in Malaysia, and collected the information via website or interview with faculty of T&CM in universities/colleges and Division of T&CM, Ministry of Health, Malaysia. T&CM education in Malaysia has been following China’s T&CM systems for 50 years. Currently, Division of T&CM, Ministry of Health; and Ministry of Higher Education has approved 11 institutions to offer T&CM education. Students may major in Chinese herbal medicine, acupuncture, or other T&CM subjects. Generally, clinical training programs in China, Taiwan, or Australia include substantial proportion of clinical training. We report on the general information of T&CM education in Malaysia. This result would be the first-stage information for the establishment of a strategy regarding the enhancement of T&CM education in Malaysia. PMID:28853309

Brazilian Soybean Yields and Yield Gaps Vary with Farm Size

Understanding the farm size-specific characteristics of crop yields and yield gaps may help to improve yields by enabling better targeting of technical assistance and agricultural development programs. Linking remote sensing-based yield estimates with property boundaries provides a novel view of the relationship between farm size and yield structure (yield magnitude, gaps, and stability over time). A growing literature documents variations in yield gaps, but largely ignores the role of farm size as a factor shaping yield structure. Research on the inverse farm size-productivity relationship (IR) theory - that small farms are more productive than large ones all else equal - has documented that yield magnitude may vary by farm size, but has not considered other yield structure characteristics. We examined farm size - yield structure relationships for soybeans in Brazil for years 2001-2015. Using out-of-sample soybean yield predictions from a statistical model, we documented 1) gaps between the 95th percentile of attained yields and mean yields within counties and individual fields, and 2) yield stability defined as the standard deviation of time-detrended yields at given locations. We found a direct relationship between soy yields and farm size at the national level, while the strength and the sign of the relationship varied by region. Soybean yield gaps were found to be inversely related to farm size metrics, even when yields were only compared to farms of similar size. The relationship between farm size and yield stability was nonlinear, with mid-sized farms having the most stable yields. The work suggests that farm size is an important factor in understanding yield structure and that opportunities for improving soy yields in Brazil are greatest among smaller farms.

To determine prevalence of utilization and social and economic profile of those using complementary and alternative medicine in the medium sized Brazilian city of Montes Claros, MG. A transversal descriptive study was conducted. The sample of 3090 people was probabilistic, by clusters using the household as the sample unit for interview of both genders, older than 18 years. Data were collected by semi-structured questionnaires. Utilization of complementary and alternative medicine was of 8.9% when only those involving costs such as homeopathy, acupuncture, chiropractics, techniques of relaxation/ meditation and massage are considered and of 70.0%, when all therapies found were included. Prevalent were prayers to God (52.0%), popular medicines (30.9%), physical exercises (25.5%), faith healers (15.0%), popular diets (7.1%), massage (4.9%), relaxation/meditation (2.8%), homeopathy (2.4%), and groups of self-help (1.9%), chiropractics (1.7%), acupuncture (1.5%) and orthomolecular medicine (0.2%). Women, Catholic, married of higher income and education were positively associated with utilization of therapies involving expenses. Complementary and alternative medicine is used by a significant number of those interviewed. Gender, religion, marital status, income and education were positively associated with utilization of complementary and alternative medicine. Access of those with less income and education could increase the utilization of the options that involve expenses.

Complementation image is often used as a guard technology in the trademark and paper currency. The key point of recognizing this kind of images is judging the complementary effect of complementation printing. The perspective images are usually not clear and legible, so it is difficult to recognize them. In this paper, a new method is proposed. Firstly, capture the image by reflex. Secondly, find the same norm to man-made pair printing. Lastly, judge the true and false of paper currency by the complementary effect of complementation printing. This is the purpose of inspecting the false. Theoretic analysis and simulation results reveal that the effect of man-made pair printing is good, the method has advantages such as simplicity, high calculating speed, and good robust to different RMB. The experiment results reveal that the conclusion is reasonable, and demonstrates that this approach is effective.

Learning from nature: binary cooperative complementary nanomaterials.

Su, Bin; Guo, Wei; Jiang, Lei

2015-03-01

In this Review, nature-inspired binary cooperative complementary nanomaterials (BCCNMs), consisting of two components with entirely opposite physiochemical properties at the nanoscale, are presented as a novel concept for the building of promising materials. Once the distance between the two nanoscopic components is comparable to the characteristic length of some physical interactions, the cooperation between these complementary building blocks becomes dominant and endows the macroscopic materials with novel and superior properties. The first implementation of the BCCNMs is the design of bio-inspired smart materials with superwettability and their reversible switching between different wetting states in response to various kinds of external stimuli. Coincidentally, recent studies on other types of functional nanomaterials contribute more examples to support the idea of BCCNMs, which suggests a potential yet comprehensive range of future applications in both materials science and engineering. © 2014 WILEY-VCH Verlag GmbH & Co.

Segmentation and clustering as complementary sources of information

NASA Astrophysics Data System (ADS)

Dale, Michael B.; Allison, Lloyd; Dale, Patricia E. R.

2007-03-01

This paper examines the effects of using a segmentation method to identify change-points or edges in vegetation. It identifies coherence (spatial or temporal) in place of unconstrained clustering. The segmentation method involves change-point detection along a sequence of observations so that each cluster formed is composed of adjacent samples; this is a form of constrained clustering. The protocol identifies one or more models, one for each section identified, and the quality of each is assessed using a minimum message length criterion, which provides a rational basis for selecting an appropriate model. Although the segmentation is less efficient than clustering, it does provide other information because it incorporates textural similarity as well as homogeneity. In addition it can be useful in determining various scales of variation that may apply to the data, providing a general method of small-scale pattern analysis.

Quantifying yield gaps in wheat production in Russia

Crop yields must increase substantially to meet the increasing demands for agricultural products. Crop yield increases are particularly important for Russia because low crop yields prevail across Russia’s widespread and fertile land resources. However, reliable data are lacking regarding the spatial distribution of potential yields in Russia, which can be used to determine yield gaps. We used a crop growth model to determine the yield potentials and yield gaps of winter and spring wheat at the provincial level across European Russia. We modeled the annual yield potentials from 1995 to 2006 with optimal nitrogen supplies for both rainfed and irrigated conditions. Overall, the results suggest yield gaps of 1.51-2.10 t ha-1, or 44-52% of the yield potential under rainfed conditions. Under irrigated conditions, yield gaps of 3.14-3.30 t ha-1, or 62-63% of the yield potential, were observed. However, recurring droughts cause large fluctuations in yield potentials under rainfed conditions, even when the nitrogen supply is optimal, particularly in the highly fertile black soil areas of southern European Russia. The highest yield gaps (up to 4 t ha-1) under irrigated conditions were detected in the steppe areas in southeastern European Russia along the border of Kazakhstan. Improving the nutrient and water supply and using crop breeds that are adapted to the frequent drought conditions are important for reducing yield gaps in European Russia. Our regional assessment helps inform policy and agricultural investors and prioritize research that aims to increase crop production in this important region for global agricultural markets.

Metabolomic prediction of yield in hybrid rice.

PubMed

Xu, Shizhong; Xu, Yang; Gong, Liang; Zhang, Qifa

2016-10-01

Rice (Oryza sativa) provides a staple food source for more than 50% of the world's population. An increase in yield can significantly contribute to global food security. Hybrid breeding can potentially help to meet this goal because hybrid rice often shows a considerable increase in yield when compared with pure-bred cultivars. We recently developed a marker-guided prediction method for hybrid yield and showed a substantial increase in yield through genomic hybrid breeding. We now have transcriptomic and metabolomic data as potential resources for prediction. Using six prediction methods, including least absolute shrinkage and selection operator (LASSO), best linear unbiased prediction (BLUP), stochastic search variable selection, partial least squares, and support vector machines using the radial basis function and polynomial kernel function, we found that the predictability of hybrid yield can be further increased using these omic data. LASSO and BLUP are the most efficient methods for yield prediction. For high heritability traits, genomic data remain the most efficient predictors. When metabolomic data are used, the predictability of hybrid yield is almost doubled compared with genomic prediction. Of the 21 945 potential hybrids derived from 210 recombinant inbred lines, selection of the top 10 hybrids predicted from metabolites would lead to a ~30% increase in yield. We hypothesize that each metabolite represents a biologically built-in genetic network for yield; thus, using metabolites for prediction is equivalent to using information integrated from these hidden genetic networks for yield prediction. © 2016 The Authors The Plant Journal © 2016 John Wiley & Sons Ltd.

More information is needed by cancer clinicians regarding cancer patients' use of complementary and alternative medicine (CAM). In this qualitative study, in-depth interviews were used to obtain the reports of adult cancer patients regarding their use of CAM. Seven cancer patients (4 women, 3 men) who reported using CAM were recruited by snowball sampling. Content analysis was used to examine the interview transcriptions. Five themes and multiple categories were identified related to CAM use: (1) facing the challenges of cancer (I can't be defeated, need to cooperate with conventional medical treatment, rebuilding my confidence), (2) handling the physical and psychological distress of CAM use (extra loading due to the therapy, uncertainty and fear about the efficacy of CAM, being understood and supported, feeling guilty about being sick, (3) lifestyle disruption (altering social life, changing family living style), (4) having reasons for seeking other therapies (finding a way to cure the disease, boosting my immunity, improving my overall health status, and prolonging life and searching for peace of mind), and (5) unresolved practical concerns about CAM (finding an easy and effective way to practice CAM, needing CAM to be integrated into mainstream health care, and where to get the related information). Adult Taiwanese cancer patients who use CAM do experience burdens secondary to CAM use and prefer that oncology specialists be more informed about CAM. Oncology specialists who know where adult cancer patients could obtain helpful information about CAM would help to decrease the burdens that patients who use CAM experience.

The metamaterial layer is electrostatically actuated by applying voltage across the suspended complementary metamaterial layer and the stationary bottom metallic reflector. Thus, the effective spacing between the metamaterial layer and bottom metal reflector is varied as a function of applied voltage. With the reduction of effective spacing between the metamaterial and reflector layers, a strong spectral blue shift in the peak absorption wavelength can be achieved. With spacing change of 300 nm, the spectral shift of 0.7 μmmore » in peak absorption wavelength was obtained for near infrared spectral region. The electro-optic switching performance of the device was characterized, and a striking switching contrast of 1500% was achieved at 2.1 μm. The reported micro-electro-mechanically tunable complementary metamaterial absorber device can potentially enable a wide range of high performance electro-optical devices, such as continuously tunable filters, modulators, and electro-optic switches that form the key components to facilitate future photonic circuit applications.« less

Modelling crop yield in Iberia under drought conditions

Ribeiro, Andreia; Páscoa, Patrícia; Russo, Ana; Gouveia, Célia

2017-04-01

The improved assessment of the cereal yield and crop loss under drought conditions are essential to meet the increasing economy demands. The growing frequency and severity of the extreme drought conditions in the Iberian Peninsula (IP) has been likely responsible for negative impacts on agriculture, namely on crop yield losses. Therefore, a continuous monitoring of vegetation activity and a reliable estimation of drought impacts is crucial to contribute for the agricultural drought management and development of suitable information tools. This works aims to assess the influence of drought conditions in agricultural yields over the IP, considering cereal yields from mainly rainfed agriculture for the provinces with higher productivity. The main target is to develop a strategy to model drought risk on agriculture for wheat yield at a province level. In order to achieve this goal a combined assessment was made using a drought indicator (Standardized Precipitation Evapotranspiration Index, SPEI) to evaluate drought conditions together with a widely used vegetation index (Normalized Difference Vegetation Index, NDVI) to monitor vegetation activity. A correlation analysis between detrended wheat yield and SPEI was performed in order to assess the vegetation response to each time scale of drought occurrence and also identify the moment of the vegetative cycle when the crop yields are more vulnerable to drought conditions. The time scales and months of SPEI, together with the months of NDVI, better related with wheat yield were chosen to perform a multivariate regression analysis to simulate crop yield. Model results are satisfactory and highlighted the usefulness of such analysis in the framework of developing a drought risk model for crop yields. In terms of an operational point of view, the results aim to contribute to an improved understanding of crop yield management under dry conditions, particularly adding substantial information on the advantages of combining

Plane-wave scattering by self-complementary metasurfaces in terms of electromagnetic duality and Babinet's principle

2013-11-01

We investigate theoretically electromagnetic plane-wave scattering by self-complementary metasurfaces. By using Babinet's principle extended to metasurfaces with resistive elements, we show that the frequency-independent transmission and reflection are realized for normal incidence of a circularly polarized plane wave onto a self-complementary metasurface, even if there is diffraction. Next, we consider two special classes of self-complementary metasurfaces. We show that self-complementary metasurfaces with rotational symmetry can act as coherent perfect absorbers, and those with translational symmetry compatible with their self-complementarity can split the incident power equally, even for oblique incidences.

Spirituality and use of complementary therapies for cure in advanced cancer.

PubMed

Trinkaus, Mateya; Burman, Debika; Barmala, Niusha; Rodin, Gary; Jones, Jennifer; Lo, Christopher; Zimmermann, Camilla

2011-07-01

Complementary and alternative medicine (CAM) is frequently used by patients with advanced cancer, for a variety of reasons. We examined the use of CAM in this population, and associations of use for potential cure with spiritual faith and existential well-being. Patients with advanced cancer on a palliative care unit completed a measure of spiritual well-being (existential well-being and faith), and a survey assessing complementary therapy use and reasons for such use. Information was also gathered on demographic data, previous cancer treatment, performance status, and symptom distress. Regression analyses assessed the association between the spirituality domains of existential well-being and faith, and the use of CAM for cure. Of 123 participants, 85% had used CAM, 42% with curative intent. More than 95% would consider future use of CAM, 48% for potential cure. Previous use for cure predicted current interest in using CAM for cure (p<0.0001). Spiritual faith was associated with previous (p<0.02) and interest in future use for cure (p<0.0001). Poor existential well-being was associated with interest in future use of CAM for cure (p=0.04). Interest in considering CAM for cure was relatively high in this group of inpatients on a palliative care unit, and was associated with increased spiritual faith and decreased existential well-being. Understanding factors associated with seeking CAM for cure may help health-care professionals to support and educate patients with advanced cancer. Copyright © 2010 John Wiley & Sons, Ltd.

Effective interdisciplinary communication is important to achieve better quality in health care. The aims of this study were to compare conventional and complementary providers' experience of communication about complementary therapies and conventional medicine with their cancer patients, and to investigate how they experience interdisciplinary communication and cooperation. This study analyzed data from a self-administrated questionnaire. A total of 606 different health care providers, from four counties in Norway, completed the questionnaire. The survey was developed to describe aspects of the communication pattern among oncology doctors, nurses, family physicians and complementary therapists (acupuncturists, massage therapists and reflexologists/zone-therapists). Between-group differences were analyzed using chi-square, ANOVA and Fisher's exact tests. Significance level was defined as p < 0.05 without adjustment for multiple comparisons. Conventional providers and complementary therapists had different patterns of communication with their cancer patients regarding complementary therapies. While complementary therapists advised their patients to apply both complementary and conventional modalities, medical doctors were less supportive of their patients' use of complementary therapies. Of conventional providers, nurses expressed more positive attitudes toward complementary therapies. Opportunities to improve communication between conventional and complementary providers were most strongly supported by complementary providers and nurses; medical doctors were less supportive of such attempts. A number of doctors showed lack of respect for complementary therapists, but asked for more research, guidelines for complementary modalities and training in conventional medicine for complementary therapists. For better quality of care, greater communication about complementary therapy use is needed between cancer patients and their conventional and complementary providers

Augustyniak, Piotr; Smoleń, Magdalena; Mikrut, Zbigniew; Kańtoch, Eliasz

2014-01-01

This paper presents a multimodal system for seamless surveillance of elderly people in their living environment. The system uses simultaneously a wearable sensor network for each individual and premise-embedded sensors specific for each environment. The paper demonstrates the benefits of using complementary information from two types of mobility sensors: visual flow-based image analysis and an accelerometer-based wearable network. The paper provides results for indoor recognition of several elementary poses and outdoor recognition of complex movements. Instead of complete system description, particular attention was drawn to a polar histogram-based method of visual pose recognition, complementary use and synchronization of the data from wearable and premise-embedded networks and an automatic danger detection algorithm driven by two premise- and subject-related databases. The novelty of our approach also consists in feeding the databases with real-life recordings from the subject, and in using the dynamic time-warping algorithm for measurements of distance between actions represented as elementary poses in behavioral records. The main results of testing our method include: 95.5% accuracy of elementary pose recognition by the video system, 96.7% accuracy of elementary pose recognition by the accelerometer-based system, 98.9% accuracy of elementary pose recognition by the combined accelerometer and video-based system, and 80% accuracy of complex outdoor activity recognition by the accelerometer-based wearable system.

Can, Gulbeyaz; Demir, Melike; Aydiner, Adnan

2012-01-01

Summary Background Most breast cancer patients use complementary and alternative medicine (CAM), usually in parallel with their conventional treatments. This study was planned to determine the prevalence and determining factors for use of CAM by breast cancer patients undergoing chemotherapy. Patients and Methods This descriptive study was carried out between October 2010 and May 2011, and included 96 patients at the Istanbul University Institute of Oncology. The Patient Characteristics form and Complementary and Alternative Medicine Scale were used for data collection. Descriptive and non-parametric tests were performed, and logistic regression analysis was used to predict factors affecting CAM use. Results Praying was the most frequently used form of CAM, and most of the herbal supplements used by patients were harmless. Herbal use was higher among patients who had local disease (relative risk (RR) 4.48%, 95% confidence interval (CI) 1.12–17.95), and worship was more common among those who had not undergone surgery (RR 4.66%, 95% CI 1.64–13.20). Conclusion The CAM approaches used by patients were found to be safe. However, sage and flax seed usage for estrogen-and progesterone-positive patients and exercise for patients with spinal metastasis can be inappropriate approaches. It is important to question and inform patients about CAM use during treatment. PMID:24715829

Background Insufficiencies in complementary feeding put infants and young children at increased risk of undernutrition. Till now, most Indian studies have looked at the individual level determinants of complementary feeding practices. We aimed to evaluate the association of frontline worker (FLW) provided nutritional counselling services, with change in community level indicators of complementary feeding practices among 9–11 month old children over time. Methods The study data was obtained from five rounds of ‘Lot Quality Assurance Sampling’ survey in eight districts of Bihar, an impoverished Indian state. The surveys were conducted as evaluation exercises for the ‘Integrated Family Health Initiative (IFHI)’–a multi-faceted program aimed at improving the maternal and child health outcomes in Bihar. The main outcome indicators were—current breastfeeding, age-appropriate minimum frequency of semi-solid food, age-appropriate minimum quantity of semi-solid food, initiation of complementary feeding at the right age, and dietary diversity. Repeated measures analysis was performed to determine the association of changes in the outcome indicators with coverage of FLW-provided counselling services. Results Visits by FLW, advices on age-appropriate frequency and handwashing were significant predictors of receiving age-appropriate frequency of feeding. The determinants of receiving age-appropriate quantity were—advices on age appropriate frequency and advices on handwashing. Receiving food support from AWC and FLW visits were significantly associated with initiating complementary feeding at the right age. Conclusions The present study identified the critical elements among the different types of FLW-provided services. The study findings, from an economically and socially underdeveloped region of India, would inform the relevant programs about the nutritional counselling services that need to be emphasized upon for reducing the burden of childhood malnutrition

2007-01-01

This review evaluated the effect of complementary and alternative medicine on pain during labor with conventional scientific methods using electronic data bases through 2006 were used. Only randomized controlled trials with outcome measures for labor pain were kept for the conclusions. Many studies did not meet the scientific inclusion criteria. According to the randomized control trials, we conclude that for the decrease of labor pain and/or reduction of the need for conventional analgesic methods: (i) There is an efficacy found for acupressure and sterile water blocks. (ii) Most results favored some efficacy for acupuncture and hydrotherapy. (iii) Studies for other complementary or alternative therapies for labor pain control have not shown their effectiveness.

2014-12-01

This is a review of the different complementary techniques that are useful for optimizing home mechanical ventilation (HMV). Airway clearance is very important in patients with HMV and many patients, particularly those with reduced peak cough flow, require airway clearance (manual or assisted) or assisted cough techniques (manual or mechanical) and suctioning procedures, in addition to ventilation. In the case of invasive HMV, good tracheostomy cannula management is essential for success. HMV patients may have sleep disturbances that must be taken into account. Sleep studies including complete polysomnography or respiratory polygraphy are helpful for identifying patient-ventilator asynchrony. Other techniques, such as bronchoscopy or nutritional support, may be required in patients on HMV, particularly if percutaneous gastrostomy is required. Information on treatment efficacy can be obtained from HMV monitoring, using methods such as pulse oximetry, capnography or the internal programs of the ventilators themselves. Finally, the importance of the patient's subjective perception is reviewed, as this may potentially affect the success of the HMV. Copyright © 2014 SEPAR. Published by Elsevier Espana.

A metamaterial terahertz modulator based on complementary planar double-split-ring resonator

NASA Astrophysics Data System (ADS)

Wang, Chang-hui; Kuang, Deng-feng; Chang, Sheng-jiang; Lin, Lie

2013-07-01

A metamaterial based on complementary planar double-split-ring resonator (DSRR) structure is presented and demonstrated, which can optically tune the transmission of the terahertz (THz) wave. Unlike the traditional DSRR metamaterials, the DSRR discussed in this paper consists of two split rings connected by two bridges. Numerical simulations with the finite-difference time-domain (FDTD) method reveal that the transmission spectra of the original and the complementary metamaterials are both in good agreement with Babinet's principle. Then by increasing the carrier density of the intrinsic GaAs substrate, the magnetic response of the complementary special DSRR metamaterial can be weakened or even turned off. This metamaterial structure is promised to be a narrow-band THz modulator with response time of several nanoseconds.

How Big Was It? Getting at Yield

NASA Astrophysics Data System (ADS)

Pasyanos, M.; Walter, W. R.; Ford, S. R.

2013-12-01

One of the most coveted pieces of information in the wake of a nuclear test is the explosive yield. Determining the yield from remote observations, however, is not necessarily a trivial thing. For instance, recorded observations of seismic amplitudes, used to estimate the yield, are significantly modified by the intervening media, which varies widely, and needs to be properly accounted for. Even after correcting for propagation effects such as geometrical spreading, attenuation, and station site terms, getting from the resulting source term to a yield depends on the specifics of the explosion source model, including material properties, and depth. Some formulas are based on assumptions of the explosion having a standard depth-of-burial and observed amplitudes can vary if the actual test is either significantly overburied or underburied. We will consider the complications and challenges of making these determinations using a number of standard, more traditional methods and a more recent method that we have developed using regional waveform envelopes. We will do this comparison for recent declared nuclear tests from the DPRK. We will also compare the methods using older explosions at the Nevada Test Site with announced yields, material and depths, so that actual performance can be measured. In all cases, we also strive to quantify realistic uncertainties on the yield estimation.

The purpose of this study was to examine the frequency of complementary and alternative medicine usage in asthmatic patients living in the west of Turkey, the most frequently used complementary and alternative medicine methods and socio-demographic factors affecting this and factors related to the disease. While the rate of complementary and alternative medicine usage in asthmatic patients and the reasons for using it vary, practices specific to different countries and regions are of interest. Differing cultural and social factors even in geographically similar regions can affect the type of complementary and alternative medicine used. Two hundred asthmatic patients registered in the asthma outpatient clinic of a large hospital in Turkey and who had undergone pulmonary function tests within the previous six months were included in this study, which was planned according to a descriptive design. The patients filled out a questionnaire on their demographic characteristics and complementary and alternative medicine usage. The proportion of patients who reported using one or more of the complementary and alternative medicine methods was 63·0%. Of these patients, 61·9% were using plants and herbal treatments, 53·2% were doing exercises and 36·5% said that they prayed. The objectives of their use of complementary and alternative medicine were to reduce asthma-related complaints (58%) and to feel better (37·8%). The proportion of people experiencing adverse effects was 3·3% (n = 4). Factors motivating asthmatic patients to use complementary and alternative medicine were the existence of comorbid diseases and a long period since diagnosis (p < 0·05). No statistically significant difference was found between the use of complementary and alternative medicine and the severity of the disease, pulmonary function test parameters, the number of asthma attacks or hospitalisations because of asthma within the last year (p > 0·05).

The aim of this study was to describe the complementary and alternative medicine methods most commonly used to alleviate symptom distress in persons with functional gastrointestinal disorders. People with functional gastrointestinal disorders face many challenges in their everyday lives, and each individual has his/her own way of dealing with this illness. The experience of illness often leads persons with functional gastrointestinal disorders to complementary and alternative medicine as a viable healthcare choice. Quantitative and describing design. A study-specific complementary and alternative medicine questionnaire was used, including questions about complementary and alternative medicine methods used and the perceived effects of each method. Efficacy assessments for each method were preventive effect, partial symptom relief, total symptom relief or no effect. A total of 137 persons with functional gastrointestinal disorders answered the questionnaire, 62% (n = 85) women and 38% (n = 52) men. A total of 28 different complementary and alternative medicine methods were identified and grouped into four categories: nutritional, drug/biological, psychological activity and physical activity. All persons had tried at least one method, and most methods provided partial symptom relief. Persons with functional gastrointestinal disorders commonly use complementary and alternative medicine methods to alleviate symptoms. Nurses have a unique opportunity to expand their roles in this group of patients. Increased knowledge of complementary and alternative medicine practices would enable a more comprehensive patient assessment and a better plan for meaningful interventions that meet the needs of individual patients. © 2011 Blackwell Publishing Ltd.

The early introduction of complementary foods is common in Middle Eastern countries but little is known about the determinants of this practice in this region. This prospective cohort study conducted from October 2007 to October 2008 investigated the determinants of the very early (before 17 weeks) introduction of complementary foods in Kuwait and compared rates of this practice against rates reported in the mid-1990s. A total of 373 women were recruited from maternity hospitals in Kuwait City and followed to 26 weeks postpartum. Data on complementary feeding practices were available from 303 women. Multivariate logistic regression was used to estimate the association of very early introduction of complementary foods with infant sex and maternal characteristics including age, years of education, employment intentions at 6 months postpartum, parity, prepregnancy body mass index, and prepregnancy smoking status. All infants had received complementary foods by 26 weeks of age, with 30.4% receiving complementary foods before 17 weeks of age. Women born in other Arabic countries were less likely to introduce complementary foods before 17 weeks (adjusted odds ratio [adj OR] = 0.40; 95% confidence interval [CI], 0.22-0.73) than women born in Kuwait. Women who were exclusively formula feeding at 6 weeks postpartum were less likely to introduce complementary foods before 17 weeks (adj OR = 0.40; 95% CI, 0.23-0.71) than women who were still breastfeeding. Compared to the mid-1990s, fewer infants in Kuwait were receiving complementary foods before 17 weeks. Nevertheless, all infants had received complementary foods by 6 months of age. © The Author(s) 2015.

Intensive care units are care centers where, in order to provide the maximum benefit to individuals whose life is in danger, many lifesaving technological tools and devices are present, and morbidity and mortality rates are high. In the intensive care unit, when classic treatments fail or become unbearable because of side effects, complementary methods have been suggested to be the best alternative. Complementary health approaches are methods that are used both for the continuation and the improvement of the well-being of an individual and as additions to medical treatments that are based on a holistic approach. These applications are especially helpful in the treatment of the stresses, anxieties, and other symptoms of unstable patients in the intensive care unit who do not tolerate traditional treatment methods well, increasing their psychological and physiological well-being, helping them sleep and rest. In intensive care patients, in order to decrease the incidence of postoperative atrial fibrillation, antiemetic and medicine needs, mechanical ventilation duration, and the intensity of the disease as well as to cope with symptoms such as pain, anxiety, physiological parameters, dyspnea, and sleep problems, body-mind interventions such as massage, reflexology, acupressure, aromatherapy, music therapy, energy therapies (healing touch, therapeutic touch, the Yakson method), and prayer are used as complementary health approaches.

Solution-derived carbon nanotube (CNT) network films with high semiconducting purity are suitable materials for the wafer-scale fabrication of field-effect transistors (FETs) and integrated circuits (ICs). However, it is challenging to realize high-performance complementary metal-oxide semiconductor (CMOS) FETs with high yield and stability on such CNT network films, and this difficulty hinders the development of CNT-film-based ICs. In this work, we developed a doping-free process for the fabrication of CMOS FETs based on solution-processed CNT network films, in which the polarity of the FETs was controlled using Sc or Pd as the source/drain contacts to selectively inject carriers into the channels. The fabricated top-gated CMOS FETs showed high symmetry between the characteristics of n- and p-type devices and exhibited high-performance uniformity and excellent scalability down to a gate length of 1 μm. Many common types of CMOS ICs, including typical logic gates, sequential circuits, and arithmetic units, were constructed based on CNT films, and the fabricated ICs exhibited rail-to-rail outputs because of the high noise margin of CMOS circuits. In particular, 4-bit full adders consisting of 132 CMOS FETs were realized with 100% yield, thereby demonstrating that this CMOS technology shows the potential to advance the development of medium-scale CNT-network-film-based ICs.

The prospect of using low-temperature processable organic semiconductors to implement transistors, circuits, displays and sensors on arbitrary substrates, such as glass or plastics, offers enormous potential for a wide range of electronic products. Of particular interest are portable devices that can be powered by small batteries or by near-field radio-frequency coupling. The main problem with existing approaches is the large power consumption of conventional organic circuits, which makes battery-powered applications problematic, if not impossible. Here we demonstrate an organic circuit with very low power consumption that uses a self-assembled monolayer gate dielectric and two different air-stable molecular semiconductors (pentacene and hexadecafluorocopperphthalocyanine, F16CuPc). The monolayer dielectric is grown on patterned metal gates at room temperature and is optimized to provide a large gate capacitance and low gate leakage currents. By combining low-voltage p-channel and n-channel organic thin-film transistors in a complementary circuit design, the static currents are reduced to below 100 pA per logic gate. We have fabricated complementary inverters, NAND gates, and ring oscillators that operate with supply voltages between 1.5 and 3 V and have a static power consumption of less than 1 nW per logic gate. These organic circuits are thus well suited for battery-powered systems such as portable display devices and large-surface sensor networks as well as for radio-frequency identification tags with extended operating range.

Development of a European Ensemble System for Seasonal Prediction: Application to crop yield

NASA Astrophysics Data System (ADS)

Terres, J. M.; Cantelaube, P.

2003-04-01

Western European agriculture is highly intensive and the weather is the main source of uncertainty for crop yield assessment and for crop management. In the current system, at the time when a crop yield forecast is issued, the weather conditions leading up to harvest time are unknown and are therefore a major source of uncertainty. The use of seasonal weather forecast would bring additional information for the remaining crop season and has valuable benefit for improving the management of agricultural markets and environmentally sustainable farm practices. An innovative method for supplying seasonal forecast information to crop simulation models has been developed in the frame of the EU funded research project DEMETER. It consists in running a crop model on each individual member of the seasonal hindcasts to derive a probability distribution of crop yield. Preliminary results of cumulative probability function of wheat yield provides information on both the yield anomaly and the reliability of the forecast. Based on the spread of the probability distribution, the end-user can directly quantify the benefits and risks of taking weather-sensitive decisions.

Alternative and complementary reinforcers as mechanisms linking adolescent conduct problems and substance use.

The present study tested the hypothesis that teens who engage in conduct problems are more likely to use substances because they engage in fewer alternative reinforcing (i.e., pleasurable) substance-free activities and more complementary reinforcing substance-associated activities. In a cross-sectional, correlational design, 9th grade students (N = 3,383; mean age = 14.6 years) in Los Angeles, California, U.S.A. completed surveys in 2013 measuring conduct problems (e.g., stealing, lying, getting in fights); alternative and complementary reinforcement; use of a number of licit, illicit, and prescription drugs; and other cofactors. Conduct problems were positively associated with past 6-month use of any substance (yes/no) among the overall sample and past 30-day use frequency on a composite index that included 6 substances among past 6-month users. These associations were statistically mediated by diminished alternative reinforcement and increased complementary reinforcement when adjusting for relevant covariates. Conduct problems were associated with lower engagement in alternative reinforcers and increased engagement in complementary reinforcers, which, in turn, were associated with greater likelihood and frequency of substance use. Most mediational relations persisted adjusting for demographic, environmental, and intrapersonal cofactors and generalized to alcohol, cigarette, and marijuana use, although, complementary reinforcers did not significantly mediate the relation of conduct problems with alcohol use frequency. These results point to diminished alternative reinforcement and increased complementary reinforcement as mechanisms linking conduct problems and adolescent substance use. Interventions that increase access to and engagement in a diverse set of alternative substance-free activities and deter activities that complement use may prevent substance use in adolescents who engage in conduct problems.

Timing of the introduction of complementary feeding and risk of childhood obesity: a systematic review.

PubMed

Pearce, J; Taylor, M A; Langley-Evans, S C

2013-10-01

The World Health Organisation recommends exclusive breastfeeding until 6 months of age and continued breastfeeding until 2 years of age or beyond. Appropriate complementary foods should be introduced in a timely fashion, beginning when the infant is 6 months old. In developing countries, early or inappropriate complementary feeding may lead to malnutrition and poor growth, but in countries such as the United Kingdom and United States of America, where obesity is a greater public health concern than malnutrition, the relationship to growth is unclear. We conducted a systematic review of the literature that investigated the relationship between the timing of the introduction of complementary feeding and overweight or obesity during childhood. Electronic databases were searched from inception until 30 September 2012 using specified keywords. Following the application of strict inclusion/exclusion criteria, 23 studies were identified and reviewed by two independent reviewers. Data were extracted and aspects of quality were assessed using an adapted Newcastle-Ottawa scale. Twenty-one of the studies considered the relationship between the time at which complementary foods were introduced and childhood body mass index (BMI), of which five found that introducing complementary foods at <3 months (two studies), 4 months (2 studies) or 20 weeks (one study) was associated with a higher BMI in childhood. Seven of the studies considered the association between complementary feeding and body composition but only one study reported an increase in the percentage of body fat among children given complementary foods before 15 weeks of age. We conclude that there is no clear association between the timing of the introduction of complementary foods and childhood overweight or obesity, but some evidence suggests that very early introduction (at or before 4 months), rather than at 4-6 months or >6 months, may increase the risk of childhood overweight.

Many women would like to avoid pharmacological or invasive methods of pain management in labour and this may contribute towards the popularity of complementary methods of pain management. This review examined currently available evidence supporting the use of alternative and complementary therapies for pain management in labour. To examine the effects of complementary and alternative therapies for pain management in labour on maternal and perinatal morbidity. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (February 2006), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2006, Issue 1), MEDLINE (1966 to February 2006), EMBASE (1980 to February 2006) and CINAHL (1980 to February 2006). The inclusion criteria included published and unpublished randomised controlled trials comparing complementary and alternative therapies (but not biofeedback) with placebo, no treatment or pharmacological forms of pain management in labour. All women whether primiparous or multiparous, and in spontaneous or induced labour, in the first and second stage of labour were included. Meta-analysis was performed using relative risks for dichotomous outcomes and mean differences for continuous outcomes. The outcome measures were maternal satisfaction, use of pharmacological pain relief and maternal and neonatal adverse outcomes. Fourteen trials were included in the review with data reporting on 1537 women using different modalities of pain management; 1448 women were included in the meta-analysis. Three trials involved acupuncture (n = 496), one audio-analgesia (n = 24), two trials acupressure (n = 172), one aromatherapy (n = 22), five trials hypnosis (n = 729), one trial of massage (n = 60), and relaxation (n = 34). The trials of acupuncture showed a decreased need for pain relief (relative risk (RR) 0.70, 95% confidence interval (CI) 0.49 to 1.00, two trials 288 women). Women taught self-hypnosis had decreased requirements for pharmacological

Complementary and alternative medicine: Interaction and communication between midwives and women.

Many pregnant women use complementary and alternative medicine. Although midwives are often supportive, how they communicate with women about the safe use of these therapies has received limited research attention. The aim of this study was to explore how midwives interact with women regarding use of complementary and alternative medicine during pregnancy. We utilised grounded theory methodology to collect and analyse data. Twenty-five midwives who worked in metropolitan hospitals situated in Melbourne, Australia, participated in the study. Data were collected from semi structured interviews and non-participant observations, over an 18-month period. How midwives communicate about complementary and alternative medicine is closely associated with the meaning they construct around the woman's role in decisionmaking. Most aim to work in a manner consistent with the midwifery partnership model and share the responsibility for decisions regarding complementary and alternative medicine. However, although various therapies were commonly discussed, usually the pregnant woman initiated the dialogue. A number of contextual conditions such as the biomedical discourse, lack of knowledge, language barriers and workplace constraints, limited communication in some situations. Midwives often interact with women interested in using CAM. Most value the woman's autonomy and aim to work in partnership. However, various contextual conditions restrain overt CAM communication in clinical practice. Copyright © 2014 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

Many pediatric patients use complementary and alternative medicine, especially when facing a chronic illness for which treatment options are limited. So far, research on the use of complementary and alternative medicine in patients with functional gastrointestinal disease has been scarce. This study was designed to assess complementary and alternative medicine use in children with different gastrointestinal diseases, including functional disorders, to determine which factors predicted complementary and alternative medicine use and to assess the willingness of parents to participate in future studies on complementary and alternative medicine efficacy and safety. The prevalence of complementary and alternative medicine use was assessed by using a questionnaire for 749 children visiting pediatric gastroenterology clinics of 9 hospitals in the Netherlands. The questionnaire consisted of 35 questions on the child's gastrointestinal disease, medication use, health status, past and future complementary and alternative medicine use, reasons for its use, and the necessity of complementary and alternative medicine research. In this study population, the frequency of complementary and alternative medicine use was 37.6%. A total of 60.3% of this group had used complementary and alternative medicine specifically for their gastrointestinal disease. This specific complementary and alternative medicine use was higher in patients with functional disorders than organic disorders (25.3% vs 17.2%). Adverse effects of allopathic medication, school absenteeism, age complementary and alternative medicine use. Almost all (93%) of the parents considered it important that pediatricians initiate complementary and alternative medicine research, and 51% of parents were willing to participate in future complementary and alternative medicine trials.

2009-12-01

Complementary and alternative medicine (CAM), also referred to as holistic, or integrative, medicine, are terms that describe a heterogeneous collection of nontraditional therapies, from chemical substances, to biofeedback, to prayer. This review focuses on CAM in pediatric patients with type 1 and type 2 diabetes. CAM prevalence in this population and the specific modalities that have been studied in children are described. Randomized, placebo-controlled, prospective studies in young adults are evaluated for their applicability to pediatric patients. CAM's "complementary" role is emphasized, as there is evidence of significant morbidity when CAM replaces standard-of-care therapy.

Many parents do not follow recommendations for the timing of introduction of complementary feeding. The aim of this study was to identify determinants associated with the timing of introduction of complementary feeding in a multiethnic birth cohort. Subjects were 3561 mothers and infants participating in a prospective cohort study. The timing of introduction of complementary feeding and maternal and infant characteristics were obtained by parent-derived questionnaires. Regression analyses were performed to identify determinants for the timing of introduction of complementary feeding (<3, 3-6 and ≥ 6 months). In total, 62% of infants were introduced to complementary feeding before the age of 6 months. Determinants for very early (<3 months) introduction were being a single parent and infant day care attendance. Determinants for early (3-6 months) introduction were young maternal age, multiple parities, no infant family history of asthma, atopy and no infant history of allergy to cow's milk. Determinants for both very early and early introduction were low educational level and not fully breastfeeding for 4 months. Maternal educational level was only significantly associated with the timing of introduction in mothers of Western origin. This study confirmed determinants for the timing of introduction of complementary feeding that have been identified by previous studies, which may be appropriate targets for education and guidance. Moreover, mothers whose infants attend day care and have a family history of asthma, atopy or allergy to cow's milk may need guidance to follow infant feeding recommendations.

Effective communication about the use of complementary and integrative medicine in cancer care.

PubMed

Frenkel, Moshe; Cohen, Lorenzo

2014-01-01

Complementary and integrative medicine (CIM) is becoming an increasingly popular and visible component of oncology care. Many patients affected by cancer and their family members are looking for informed advice and desire communication with their physicians about CIM use. Patients affected by cancer come to discuss CIM use with intense emotions and are experiencing an existential crisis that cannot be ignored. Effective communication is crucial in establishing trust with these patients and their families. Communication is now recognized as a core clinical skill in medicine, including cancer care, and is important to the delivery of high-quality care. The quality of communication affects patient satisfaction, decision-making, patient distress and well-being, compliance, and even malpractice litigation. The communication process about CIM use requires a very sensitive approach that depends on effective communication skills, such as experience in listening, encouraging hope, and ability to convey empathy and compassion. This process can be divided into two parts: the "how" and the "what". The "how" relates to the change in clinician attitude, the process of gathering information, addressing patients' unmet needs and emotions, and dealing with uncertainty. The "what" relates to the process of information exchange while assisting patients in decisions about CIM use by using reliable information sources, leading to informed decision-making.

On the non-uniqueness of sediment yield

Kim, J.; Ivanov, V. Y.; Katopodes, N.

2012-12-01

Estimation of sediment yield at the catchment scale plays an important role for optimal design of hydraulic structures, such as bridges, culverts, reservoirs, and detention basins, as well as making informed decisions in environmental management. Many experimental studies focused on obtaining flow and sediment data in search of unique relationships between runoff (specifically, volume and peak) and sediment characteristics. These relationships were employed to predict sediment yield from flow information. However, despite the same flow volume, the actual sediment yield produced by river basins can vary significantly depending on several conditions: (i) the catchment size, (ii) land use, topography, and soil type, (iii) climatic variations or characteristics , and (iv) initial conditions of soil moisture and soil surface . Additionally, shield formation by relatively larger particles can be one of the possible controllers of erosion and net sediment transport. Smaller particles have low settling velocities and tend to move far from their original position of detachment. Conversely, larger particles can settle quickly near their original locations. Eventually, such particles can form a shield on soil bed and protect underlying soil from rainfall detachment and runoff entrainment. The shield formation and temporal development can be influenced by rainfall intensity, frequency, and volume. Rainfall influences the generation of runoff leading to different conditions of flow depth and velocity that can perturb intact soil into a loose condition. In this study, we numerically investigate the effects of precipitation patterns on the generation of sediment yield. In particular, we address reasons of non-uniqueness of basin sediment yield for the same runoff volume as well as causes of unsteady phenomena in erosion processes under steady state flow conditions. For numerical simulations, the two-dimensional Hairsine-Rose model coupled with a fully distributed hydrology and

2014-05-01

To meet growing global food demand with limited land and reduced environmental impact, agricultural greenhouse gas (GHG) emissions are increasingly evaluated with respect to crop productivity, i.e., on a yield-scaled as opposed to area basis. Here, we compiled available field data on CH4 and N2 O emissions from rice production systems to test the hypothesis that in response to fertilizer nitrogen (N) addition, yield-scaled global warming potential (GWP) will be minimized at N rates that maximize yields. Within each study, yield N surplus was calculated to estimate deficit or excess N application rates with respect to the optimal N rate (defined as the N rate at which maximum yield was achieved). Relationships between yield N surplus and GHG emissions were assessed using linear and nonlinear mixed-effects models. Results indicate that yields increased in response to increasing N surplus when moving from deficit to optimal N rates. At N rates contributing to a yield N surplus, N2 O and yield-scaled N2 O emissions increased exponentially. In contrast, CH4 emissions were not impacted by N inputs. Accordingly, yield-scaled CH4 emissions decreased with N addition. Overall, yield-scaled GWP was minimized at optimal N rates, decreasing by 21% compared to treatments without N addition. These results are unique compared to aerobic cropping systems in which N2 O emissions are the primary contributor to GWP, meaning yield-scaled GWP may not necessarily decrease for aerobic crops when yields are optimized by N fertilizer addition. Balancing gains in agricultural productivity with climate change concerns, this work supports the concept that high rice yields can be achieved with minimal yield-scaled GWP through optimal N application rates. Moreover, additional improvements in N use efficiency may further reduce yield-scaled GWP, thereby strengthening the economic and environmental sustainability of rice systems. © 2013 John Wiley & Sons Ltd.

The Lower Mekong Region has been experiencing frequent and prolonged droughts resulting in severe damage to agricultural production leading to food insecurity and impacts on livelihoods of the farming communities. Climate variability further complicates the situation by making drought harder to forecast. The Regional Drought and Crop Yield Information System (RDCYIS), developed by SERVIR-Mekong, helps decision makers to take effective measures through monitoring, analyzing and forecasting of drought conditions and providing early warnings to farmers to make adjustments to cropping calendars. The RDCYIS is built on regionally calibrated Regional Hydrologic Extreme Assessment System (RHEAS) framework that integrates the Variable Infiltration Capacity (VIC) and Decision Support System for Agro-technology Transfer (DSSAT) models, allowing both nowcast and forecast of drought. The RHEAS allows ingestion of numerus freely available earth observation and ground observation data to generate and customize drought related indices, variables and crop yield information for better decision making. The Lower Mekong region has experienced severe drought in 2016 encompassing the region's worst drought in 90 years. This paper presents the simulation of the 2016 drought event using RDCYIS based on its hindcast and forecast capabilities. The regionally calibrated RDCYIS can help capture salient features of drought through a variety of drought indices, soil variables, energy balance variables and water balance variables. The RDCYIS is capable of assimilating soil moisture data from different satellite products and perform ensemble runs to further reduce the uncertainty of it outputs. The calibrated results have correlation coefficient around 0.73 and NSE between 0.4-0.5. Based on the acceptable results of the retrospective runs, the system has the potential to generate reliable drought monitoring and forecasting information to improve decision-makings at operational, technological and

There is increasing interest in complementary and alternative medicine (CAM) among healthcare professions. However, no studies have been conducted in Sweden or in a surgical context. The aim of this study is to describe different perceptions of complementary therapies among registered healthcare professions in Swedish surgical care. Sixteen interviews were conducted with registered physicians, nurses, physiotherapists and clinical dieticians at a Swedish university hospital. Analysis was made with a phenomenographic research approach. The findings showed variations in perceptions of the definition of complementary therapies. A constructive approach toward use was observed, but there was a conflict in matters of indications and contraindications, and also criticism over a lack of knowledge. There was seen to be a need for education to be able to act professionally. Scepticism over high costs of treatment was highlighted. In conclusion, a need for policies on management, education and research in the field of CAM should be addressed. Copyright © 2010 Elsevier Ltd. All rights reserved.

Achieving efficient cardiac gene transfer in a large animal model has proven to be technically challenging. Prior strategies have employed cardio-pulmonary bypass or dual catheterization with the aid of vasodilators to deliver vectors, such as adenovirus, adeno-associated virus or plasmid DNA. While single stranded adeno-associated virus vectors have shown the greatest promise, they suffer from delayed expression, which might be circumvented by using self-complementary vectors. We sought to optimize cardiac gene transfer using a percutaneous transendocardial injection catheter to deliver adeno-associated virus vectors to the canine myocardium. Four vectors were evaluated—single stranded adeno-associated virus 9, self-complementary adeno-associated virus 9, self-complementary adeno-associated virus 8, self-complementary adeno-associated virus 6—so that comparison could be made between single stranded and self complementary vectors as well as among serotypes 9, 8, and 6. We demonstrate that self-complementary adeno-associated virus is superior to single stranded adeno-associated virus and that adeno-associated virus 6 is superior to other serotypes evaluated. Biodistribution studies revealed that vector genome copies were 15 to 4000 times more abundant in the heart than in any other organ for self-complementary adeno-associated virus 6. Percutaneous transendocardial injection of self-complementary adeno-associated virus 6 is a safe, effective method for achieving efficient cardiac gene transfer. PMID:18813281

Classical and Bayesian Seismic Yield Estimation: The 1998 Indian and Pakistani Tests

NASA Astrophysics Data System (ADS)

Shumway, R. H.

2001-10-01

- The nuclear tests in May, 1998, in India and Pakistan have stimulated a renewed interest in yield estimation, based on limited data from uncalibrated test sites. We study here the problem of estimating yields using classical and Bayesian methods developed by Shumway (1992), utilizing calibration data from the Semipalatinsk test site and measured magnitudes for the 1998 Indian and Pakistani tests given by Murphy (1998). Calibration is done using multivariate classical or Bayesian linear regression, depending on the availability of measured magnitude-yield data and prior information. Confidence intervals for the classical approach are derived applying an extension of Fieller's method suggested by Brown (1982). In the case where prior information is available, the posterior predictive magnitude densities are inverted to give posterior intervals for yield. Intervals obtained using the joint distribution of magnitudes are comparable to the single-magnitude estimates produced by Murphy (1998) and reinforce the conclusion that the announced yields of the Indian and Pakistani tests were too high.

Improvement of crop yield in dry environments: benchmarks, levels of organisation and the role of nitrogen.

PubMed

Sadras, V O; Richards, R A

2014-05-01

Crop yield in dry environments can be improved with complementary approaches including selecting for yield in the target environments, selecting for yield potential, and using indirect, trait- or genomic-based methods. This paper (i) outlines the achievements of direct selection for yield in improving drought adaptation, (ii) discusses the limitations of indirect approaches in the context of levels of organization, and (iii) emphasizes trade-offs and synergies between nitrogen nutrition and drought adaptation. Selection for yield in the water- and nitrogen-scarce environments of Australia improved wheat yield per unit transpiration at a rate of 0.12kg ha(-1) mm(-1) yr(-1); for indirect methods to be justified, they must return superior rates of improvement, achieve the same rate at lower cost or provide other cost-effective benefits, such as expanding the genetic basis for selection. Slow improvement of crop adaptation to water stress using indirect methods is partially related to issues of scale. Traits are thus classified into three broad groups: those that generally scale up from low levels of organization to the crop level (e.g. herbicide resistance), those that do not (e.g. grain yield), and traits that might scale up provided they are considered in a integrated manner with scientifically sound scaling assumptions, appropriate growing conditions, and screening techniques (e.g. stay green). Predicting the scalability of traits may help to set priorities in the investment of research efforts. Primary productivity in arid and semi-arid environments is simultaneously limited by water and nitrogen, but few attempts are made to target adaptation to water and nitrogen stress simultaneously. Case studies in wheat and soybean highlight biological links between improved nitrogen nutrition and drought adaptation.

Asteroid models from photometry and complementary data sources

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kaasalainen, Mikko

I discuss inversion methods for asteroid shape and spin reconstruction with photometry (lightcurves) and complementary data sources such as adaptive optics or other images, occultation timings, interferometry, and range-Doppler radar data. These are essentially different sampling modes (generalized projections) of plane-of-sky images. An important concept in this approach is the optimal weighting of the various data modes. The maximum compatibility estimate, a multi-modal generalization of the maximum likelihood estimate, can be used for this purpose. I discuss the fundamental properties of lightcurve inversion by examining the two-dimensional case that, though not usable in our three-dimensional world, is simple to analyze,more » and it shares essentially the same uniqueness and stability properties as the 3-D case. After this, I review the main aspects of 3-D shape representations, lightcurve inversion, and the inclusion of complementary data.« less

Improving inflow forecasting into hydropower reservoirs through a complementary modelling framework

NASA Astrophysics Data System (ADS)

Gragne, A. S.; Sharma, A.; Mehrotra, R.; Alfredsen, K.

2014-10-01

Accuracy of reservoir inflow forecasts is instrumental for maximizing the value of water resources and benefits gained through hydropower generation. Improving hourly reservoir inflow forecasts over a 24 h lead-time is considered within the day-ahead (Elspot) market of the Nordic exchange market. We present here a new approach for issuing hourly reservoir inflow forecasts that aims to improve on existing forecasting models that are in place operationally, without needing to modify the pre-existing approach, but instead formulating an additive or complementary model that is independent and captures the structure the existing model may be missing. Besides improving forecast skills of operational models, the approach estimates the uncertainty in the complementary model structure and produces probabilistic inflow forecasts that entrain suitable information for reducing uncertainty in the decision-making processes in hydropower systems operation. The procedure presented comprises an error model added on top of an un-alterable constant parameter conceptual model, the models being demonstrated with reference to the 207 km2 Krinsvatn catchment in central Norway. The structure of the error model is established based on attributes of the residual time series from the conceptual model. Deterministic and probabilistic evaluations revealed an overall significant improvement in forecast accuracy for lead-times up to 17 h. Season based evaluations indicated that the improvement in inflow forecasts varies across seasons and inflow forecasts in autumn and spring are less successful with the 95% prediction interval bracketing less than 95% of the observations for lead-times beyond 17 h.

Expectations and responsibilities regarding the sale of complementary medicines in pharmacies: perspectives of consumers and pharmacy support staff.

Most sales of complementary medicines within pharmacies are conducted by pharmacy support staff. The absence of rigorous evidence for the effectiveness of many complementary medicines raises a number of ethical questions regarding the sale of complementary medicines in pharmacies. Explore (1) what consumers expect from pharmacists/pharmacies with regard to the sale of complementary medicines, and (2) how pharmacy support staff perceive their responsibilities when selling complementary medicines. One-on-one semi-structured interviews were conducted with a convenience sample of pharmacy support staff and consumers in pharmacies in Brisbane. Consumers were asked to describe their expectations when purchasing complementary medicines. Pharmacy support staff were asked to describe their responsibilities when selling complementary medicines. Interviews were conducted and analysed using the techniques developed within Grounded Theory. Thirty-three consumers were recruited from three pharmacies. Consumers described complementary medicine use as a personal health choice. Consumer expectations on the pharmacist included: select the right product for the right person, expert product knowledge and maintaining a wide range of good quality stock. Twenty pharmacy support staff were recruited from four pharmacies. Pharmacy support staff employed processes to ensure consumers receive the right product for the right person. Pharmacy support staff expressed a commitment to aiding consumers, but few evaluated the reliability of effectiveness claims regarding complementary medicines. Pharmacists need to respect the personal health choices of consumers while also putting procedures in place to ensure safe and appropriate use of complementary medicines. This includes providing appropriate support to pharmacy support staff. © 2016 Royal Pharmaceutical Society.

Joint Bayesian inference for near-surface explosion yield

NASA Astrophysics Data System (ADS)

Bulaevskaya, V.; Ford, S. R.; Ramirez, A. L.; Rodgers, A. J.

2016-12-01

A near-surface explosion generates seismo-acoustic motion that is related to its yield. However, the recorded motion is affected by near-source effects such as depth-of-burial, and propagation-path effects such as variable geology. We incorporate these effects in a forward model relating yield to seismo-acoustic motion, and use Bayesian inference to estimate yield given recordings of the seismo-acoustic wavefield. The Bayesian approach to this inverse problem allows us to obtain the probability distribution of plausible yield values and thus quantify the uncertainty in the yield estimate. Moreover, the sensitivity of the acoustic signal falls as a function of the depth-of-burial, while the opposite relationship holds for the seismic signal. Therefore, using both the acoustic and seismic wavefield data allows us to avoid the trade-offs associated with using only one of these signals alone. In addition, our inference framework allows for correlated features of the same data type (seismic or acoustic) to be incorporated in the estimation of yield in order to make use of as much information from the same waveform as possible. We demonstrate our approach with a historical dataset and a contemporary field experiment.

Proposal of indicators to evaluate complementary feeding based on World Health Organization indicators.

This study compares complementary feeding World Health Organization (WHO) indicators with those built in accordance with Brazilian recommendations (Ten Steps to Healthy Feeding). A cross-sectional study was carried out during the National Immunization Campaign against Poliomyelitis in Guarapuava-Paraná, Brazil, in 2012. Feeding data from 1,355 children aged 6-23 months were obtained through the 24 h diet recall. Based on five indicators, the proportion of adequacy was evaluated: introduction of solid, semi-solid, or soft foods; minimum dietary diversity; meal frequency; acceptable diet; and consumption of iron-rich foods. Complementary feeding showed adequacy higher than 85% in most WHO indicators, while review by the Ten Steps assessment method showed a less favorable circumstance and a high intake of unhealthy foods. WHO indicators may not reflect the complementary feeding conditions of children in countries with low malnutrition rates and an increased prevalence of overweight/obesity. The use of indicators according to the Ten Steps can be useful to identify problems and redirect actions aimed at promoting complementary feeding. © 2016 John Wiley & Sons Australia, Ltd.

Complementary and alternative medicine for treatment of irritable bowel syndrome.

Shen, Yi-Hao A; Nahas, Richard

2009-02-01

To review the evidence supporting selected complementary and alternative medicine approaches used in the treatment of irritable bowel syndrome (IBS). MEDLINE (from January 1966), EMBASE (from January 1980), and the Cochrane Database of Systematic Reviews were searched until March 2008, combining the terms irritable bowel syndrome or irritable colon with complementary therapies, alternative medicine, acupuncture, fiber, peppermint oil, herbal, traditional, yoga, massage, meditation, mind, relaxation, probiotic, hypnotherapy, psychotherapy, cognitive therapy, or behavior therapy. Results were screened to include only clinical trials, systematic reviews, and meta-analyses. Level I evidence was available for most interventions. Soluble fibre improves constipation and global IBS symptoms. Peppermint oil alleviates IBS symptoms, including abdominal pain. Probiotic trials show overall benefit for IBS but there is little evidence supporting the use of any specific strain. Hypnotherapy and cognitive-behavioural therapy are also effective therapeutic options for appropriate patients. Certain herbal formulas are supported by limited evidence, but safety is a potential concern. All interventions are supported by systematic reviews or meta-analyses. Several complementary and alternative therapies can be recommended as part of an evidence-based approach to the treatment of IBS; these might provide patients with satisfactory relief and improve the therapeutic alliance.

2014-11-01

The aim of this study was to explore how and why Australian men with cancer practice complementary therapies (CTs) and how their significant others (SOs) contribute to the regular uptake of CTs. This qualitative study employed semi-structured interviews with 26 male cancer patients and 24 SOs. Participants were purposefully sampled from a preceding Australian survey investigating the use of CTs in men with cancer (94% response rate and 86% consent rate for follow-up interview). Interviews were conducted in a metropolitan location, and the 43 interview transcripts were analyzed thematically. Three core themes were identified: men used CTs as (a) problem-focused coping (e.g., diet modification), (b) emotion-focused coping (e.g., meditation), and (c) meaning-based coping (e.g., prayer). Practicing CTs helped men to cope with physical, emotional, and spiritual concerns, although some men spoke of difficulties with practicing meditation to regulate their emotions. SOs were supportive of men's coping strategies but were only rarely involved in men's emotion-focused coping. Complementary therapies have the potential to facilitate coping with cancer, independent of any measurable physiological benefit. Our findings suggest that when clinicians engage in conversations about CTs use, they should consider the type of coping strategy employed by their patient. Such information may enhance the efficacy of some interventions (e.g., meditation) and also provide for an opportunity to discuss patients' expectations concerning CTs.

Many patients with human immunodeficiency virus infection use traditional, complementary, and alternative medicines and other practices to combat the disease, with some also using prescribed antiretroviral therapy provided by the public health sector. This study aimed to establish the awareness of public sector biomedical health care providers on the use of traditional, complementary and alternative medicines by HIV-infected patients who also used highly active antiretroviral therapy, and to determine whether this was based on patients seen or cases being reported to them. Potential risks of interactions between the prescribed antiretroviral and non-prescribed medication therapies may pose safety and effectiveness issues in patients using both types of treatment. A descriptive cross-sectional study, using a researcher administered semi-structured questionnaire, was conducted from June to August 2013 at ten public sector antiretroviral clinics in five regional, three specialised and two district hospitals in eThekwini Health District, South Africa. Questionnaires were administered through face-to face interview to 120 eligible participants consisting of doctors, nurses, pharmacists and post-basic pharmacist assistants in HIV clinical practice. The results are presented as percent or proportion with standard error (SE), or as frequency. Ninety-four respondents completed the questionnaire, yielding a response rate of 78.3 %. Almost half (48/94) were aware of patients using African traditional herbal medicines, over-the-counter supplements, unnamed complementary Ayurveda medicines and acupuncture. Twenty-three of the 94 respondents (24.4 %) said they had consulted patients who were using both antiretroviral therapy and certain types of non-prescribed medication in the previous three months. Awareness among healthcare providers on patient use of traditional, complementary and alternative medicines was relatively high. Few respondents had seen patients who used mostly

The effect of traffic lights and regulatory statements on the choice between complementary and conventional medicines in Australia: results from a discrete choice experiment.

PubMed

Spinks, Jean; Mortimer, Duncan

2015-01-01

It has been suggested that complementary medicines are currently 'under-regulated' in some countries due to their potential for harm as a direct result from side-effects or interactions; from delaying more effective care; or from the economic cost of purchasing an ineffective or inappropriate treatment. The requirement of additional labelling on complementary medicine products has been suggested in Australia and may provide additional information to consumers at the point of purchase. This paper details a unique way of testing the potential effects on consumer behaviour of including either a traffic light logo or regulatory statement on labels. Using a discrete choice experiment, data were collected in 2012 in a sample of 521 Australians with either type 2 diabetes or cardiovascular disease. We find that additional labelling can affect consumer behaviour, but in unpredictable ways. The results of this experiment are informative to further the dialogue concerning possible regulatory mechanisms. Copyright © 2014 Elsevier Ltd. All rights reserved.

Improving the complementary methods to estimate evapotranspiration under diverse climatic and physical conditions

NASA Astrophysics Data System (ADS)

Anayah, F. M.; Kaluarachchi, J. J.

2014-06-01

Reliable estimation of evapotranspiration (ET) is important for the purpose of water resources planning and management. Complementary methods, including complementary relationship areal evapotranspiration (CRAE), advection aridity (AA) and Granger and Gray (GG), have been used to estimate ET because these methods are simple and practical in estimating regional ET using meteorological data only. However, prior studies have found limitations in these methods especially in contrasting climates. This study aims to develop a calibration-free universal method using the complementary relationships to compute regional ET in contrasting climatic and physical conditions with meteorological data only. The proposed methodology consists of a systematic sensitivity analysis using the existing complementary methods. This work used 34 global FLUXNET sites where eddy covariance (EC) fluxes of ET are available for validation. A total of 33 alternative model variations from the original complementary methods were proposed. Further analysis using statistical methods and simplified climatic class definitions produced one distinctly improved GG-model-based alternative. The proposed model produced a single-step ET formulation with results equal to or better than the recent studies using data-intensive, classical methods. Average root mean square error (RMSE), mean absolute bias (BIAS) and R2 (coefficient of determination) across 34 global sites were 20.57 mm month-1, 10.55 mm month-1 and 0.64, respectively. The proposed model showed a step forward toward predicting ET in large river basins with limited data and requiring no calibration.

Specific yield: compilation of specific yields for various materials

USGS Publications Warehouse

Johnson, A.I.

1967-01-01

Specific yield is defined as the ratio of (1) the volume of water that a saturated rock or soil will yield by gravity to (2) the total volume of the rock or soft. Specific yield is usually expressed as a percentage. The value is not definitive, because the quantity of water that will drain by gravity depends on variables such as duration of drainage, temperature, mineral composition of the water, and various physical characteristics of the rock or soil under consideration. Values of specific yields nevertheless offer a convenient means by which hydrologists can estimate the water-yielding capacities of earth materials and, as such, are very useful in hydrologic studies. The present report consists mostly of direct or modified quotations from many selected reports that present and evaluate methods for determining specific yield, limitations of those methods, and results of the determinations made on a wide variety of rock and soil materials. Although no particular values are recommended in this report, a table summarizes values of specific yield, and their averages, determined for 10 rock textures. The following is an abstract of the table. [Table

2012-01-01

Given the severe and chronic problems associated with Autism Spectrum Disorders (ASD) and the limitations of available treatments, there exists a large public health need for additional interventions. As more parents are inquiring about complementary and alternative treatments (CATs), both parents and practitioners require up-to-date information about them and whether and how to integrate them into treatment. After presenting data on CAT usage patterns for ASD, we review 13 ingestible (i.e., orally administered) and 6 noningestible (i.e., externally administered) CATs for ASD. For each CAT we briefly describe its definition; rationale for use; current research support, limitations, and future directions; safety issues; and whether we currently recommend, not recommend, or find it acceptable for the treatment of ASD. We conclude this paper with recommendations for future research and ten clinical recommendations for practitioners. PMID:23243505

USE OF COMPLEMENTARY AND ALTERNATIVE MEDICINE IN GEORGIA.

In Georgia, like in most countries globally, people commonly resort to complementary and alternative medicine (CAM). However, not much is known about CAM practices there. The aim of the study was to document common practices of CAM in Georgia and related patient attitudes. We collected data from peoples who commonly use CAM at 20 service provision centers in Georgia using cluster sampling from 300 patients. We admininstered a cross-sectional survey and conducted descriptive statistical analyses. People in Georgia use CAM either for prevention to improve general health (33%) or to treat chronic conditions (36%), spending about 25 Euros per month out of pocket. Most (77%) get their knowledge about CAM from family or friends , less than half (44%) from books or media, and 11% from medical providers. A close person's advice or experience was the most common rationale given for CAM use (54%). In our sample, 17% either don't trust or are unsatisfied with conventional medicine, 29% found CAM treatment "very effective" and 61% "quite/partially" effective; only 5% not effective. Conventional treatment was stopped in half of the cases. 35% of respondents informed their physicians of their CAM use, while about half did not. Public mistrust towards conventional medicine, CAM user high satisfaction, relatively low cost of such services in Georgia - are the factors letting us to suggest that CAM use will further increase. Frequent self taking decisions made by patients to stop physician prescribed treatment, not informing physicians on CAM use, as well as other factors put patients health at risk. Further research and capacity building in practice, education and other related aspects are needed to establish evidence-based regulation and standards for CAM in Georgia that ensure informed decision making and patient safety.

Complementary medicines in pediatric bipolar disorder.

Bogarapu, S; Bishop, J R; Krueger, C D; Pavuluri, M N

2008-02-01

The increasing number and availability of various complementary and alternative medicines (CAM) has resulted in an exponentially growing utilization of these products for everything from minor aches and pains to the treatment of mental illness. Difficulties in treating mental illnesses in children, averseness to having children take psychiatric medications, and stigma all drive patients and their families to research alternative treatments. As a result, there has been an increased utilization of CAM in psychiatry, particularly for hard to treat conditions like pediatric BD. It is important for the health care providers to be aware of the alternative treatments by some of their patients. A review of studies investigating the utility of complementary and alternative medicines in bipolar patients was conducted and selected studies were included. Omega-3 fatty acids and lecithin/ choline have preliminary data indicating potential utility in the CAM treatment for bipolar disorder while S-adenosyl methionine (SAM-e) and inositol have some data supporting their efficacy in the treatment of depressive symptoms. Some data for CAM suggest they may be useful adjunctive treatments but only little data are available to support their use as stand-alone therapy. Thus, the conventional medicines remain the first choice in pediatric bipolar management. Healthcare providers need to routinely inquire about the utilization of these treatments by their patients and become familiar with the risks and benefits involved with their use in children.

Complementary alternative medicine use in children with type 1 diabetes mellitus in Erzurum, Turkey.

PubMed

Arýkan, Duygu; Sívríkaya, Sibel Karaca; Olgun, Nermin

2009-08-01

The aims of this study were: (i) to determine the types of complementary and alternative medicine use among children with type I diabetes mellitus as reported by parents and (ii) to describe sociodemographic and medical factors associated with the use of such treatments in families residing in Eastern Turkey. Type 1 diabetes mellitus is a tremendously challenging and complex disease for children and families to manage. Therefore, the use of complementary and alternative medicines among children with type 1 diabetes is becoming increasingly popular. Survey. Parents of 100 paediatric patients (who were diagnosed with type 1 diabetes at least 6 months prior to the study) who visited the participating paediatric endocrinology multidisciplinary centres and clinics for diabetes management were included in the study. Data were collected by using a semi-structured questionnaire. Results. Fifty-two per cent of the parents reported the use of one or more complementary alternative medicine therapies. Most such users (59.6%) were using oral herbal preparations; including morus alba (leaves) aloe vera and stinging nettle. Since we found that 78.6% of those using herbals were satisfied with their results and 69.2% were planning to continue use, it is important for healthcare providers to have relevant knowledge about complementary alternative medicine use and learn about its efficacy and effects (positive and adverse) of these treatments. Relevance to clinical practice. Botanical substitute for insulin seems unlikely, but complementary alternative treatments may provide valuable clues for the development of new oral hypoglycaemic agents and simple dietary agents. It is important for healthcare providers to have up-to-date knowledge about the use and effects of complementary alternative medicines in the outpatient clinical care setting.

Commercialism, choice and consumer protection: regulation of complementary medicines in Australia.

Controls on the supply and promotion of complementary medicines in Australia are weak. We used weight-loss products as an example to compare the regulation in Australia of listed complementary medicines and registered pharmaceutical products. Complementary medicines are listed without evaluation for efficacy, while conventional pharmaceutical products are registered after evaluation for quality, safety and efficacy. From 1996 to 2006, over 1000 "weight-loss" products were listed on the Australian Register of Therapeutic Goods; most contained multiple unevaluated ingredients (herbs, vitamins, minerals) of dubious efficacy. Over the same period, 10 conventional medicines were registered; each contained one evaluated ingredient of proven efficacy. The number of listed weight-loss products (and complaints about their promotion) is increasing. These appear to be a direct consequence of the decision not to evaluate listed products for efficacy and the lower fees for listing a product, compared with registration. Complaint procedures (now overloaded) are no substitute for adequate regulation at the time of market entry. Regulatory reform of listed and homoeopathic products is required.

Complementary stable carbon isotope ratio and amount of substance measurements in sports anti-doping.

The detection of steroids originating from synthetic precursors against a background of their chemically identical natural analogues has proven to be a significant challenge for doping control laboratories accredited by the World Anti-Doping Agency (WADA). The complementary application of gas chromatography-mass spectrometry (GC-MS) and gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS) has been demonstrated to provide specific detection of endogenous steroid misuse for improved anti-doping analysis. Markers of synthetically derived steroids are reviewed on the basis of abnormal urinary excretions and low (13)C content. A combinatorial approach is presented for the interpretation of GC-MS and GC-C-IRMS data in the anti-doping context. This methodology can allow all relevant information concerning an individual's metabolism to be assessed in order to make an informed decision with respect to a doping violation.

Complementary therapies for peripheral arterial disease: systematic review.

PubMed

Pittler, Max H; Ernst, Edzard

2005-07-01

While peripheral arterial disease (PAD) affects a considerable proportion of patients in the primary care setting, there is a high level of use of complementary treatment options. The aim was to assess the effectiveness of any type of complementary therapy for peripheral arterial disease. A systematic review was performed. Literature searches were conducted on Medline, Embase, Amed, and the Cochrane Library until December 2004. Hand-searches of medical journals and bibliographies were conducted. There were no restrictions regarding the language of publication. The screening of studies, selection, data extraction, the assessment of methodologic quality and validation were performed independently by the two reviewers. Data from randomized controlled trials, and systematic reviews and meta-analyses, which based their findings on the results of randomized controlled trials were included. Seven systematic reviews and meta-analyses and three additional randomized controlled trials met the inclusion criteria and were reviewed. The evidence relates to acupuncture, biofeedback, chelation therapy, CO(2)-applications and the dietary supplements Allium sativum (garlic), Ginkgo biloba (ginkgo), omega-3 fatty acids, padma 28 and Vitamin E. Most studies included only patients with peripheral arterial disease in Fontaine stage II (intermittent claudication). The reviewed RCTs, systematic reviews and meta-analyses which based their findings on the results of RCTs suggest that G. biloba is effective compared with placebo for patients with intermittent claudication. Evidence also suggests that padma 28 is effective for intermittent claudication, although more data are required to confirm these findings. For all other complementary treatment options there is no evidence beyond reasonable doubt to suggest effectiveness for patients with peripheral arterial disease.

complementary and Alternative Medicine use during pregnancy is popular in many countries, including Australia. There is currently little evidence to support this practice, which raises the question of women's motivation for use of these therapies and the experiences they encounter. this study aims to explore the perceptions, motivations and experiences of pregnant women with regard to their use of Complementary and Alternative Medicine during pregnancy. a systemic review and meta-synthesis of the available research was conducted. Five databases were explored - CINAHL Plus, Medline, PubMed, AMED and Web of Science using the search terms complementary and alternative medicine; pregnancy; and pregnant. Articles included in this meta-synthesis were screened using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses tool. ten initial themes were drawn from the six studies. These ten themes were summarised by three cluster themes. The results suggest that women are using Complementary and Alternative Medicine in their pregnancy as a means of supporting their sense of self-determination, to pursue a natural and safe childbirth, and because they experience a close affiliation with the philosophical underpinnings of Complementary and Alternative Medicine as an alternative to the biomedical model. these findings are important to practitioners, policy makers, governing bodies and researchers, providing insight into the motivations for Complementary and Alternative Medicine use by women in pregnancy.

Complementary codes for odor identity and intensity in olfactory cortex

PubMed Central

Bolding, Kevin A; Franks, Kevin M

2017-01-01

The ability to represent both stimulus identity and intensity is fundamental for perception. Using large-scale population recordings in awake mice, we find distinct coding strategies facilitate non-interfering representations of odor identity and intensity in piriform cortex. Simply knowing which neurons were activated is sufficient to accurately represent odor identity, with no additional information about identity provided by spike time or spike count. Decoding analyses indicate that cortical odor representations are not sparse. Odorant concentration had no systematic effect on spike counts, indicating that rate cannot encode intensity. Instead, odor intensity can be encoded by temporal features of the population response. We found a subpopulation of rapid, largely concentration-invariant responses was followed by another population of responses whose latencies systematically decreased at higher concentrations. Cortical inhibition transforms olfactory bulb output to sharpen these dynamics. Our data therefore reveal complementary coding strategies that can selectively represent distinct features of a stimulus. DOI: http://dx.doi.org/10.7554/eLife.22630.001 PMID:28379135

The use of complementary and alternative medicine during pregnancy is currently on the rise. A validated survey was conducted at the Central Association of Obstetrician and Gynecologists annual meeting to evaluate the knowledge, attitude, and practice of general obstetricians and gynecologists and maternal-fetal medicine specialists in America. We obtained 128 responses: 73 electronically (57%) and 55 via the paper survey (43%). Forty-five percent reported personally using complementary and alternative medicine and 9% of women respondents used complementary and alternative medicine during pregnancy. Overall, 62% had advised their patients to utilize some form of complementary and alternative medicine in pregnancy. Biofeedback, massage therapy, meditation, and yoga were considered the most effective modalities in pregnancy (median [semi-interquartile range] = 2 [0.5]). Maternal-fetal medicine specialists were significantly more likely to disagree on the use of complementary and alternative medicine for risk reduction of preterm birth compared to obstetricians and gynecologists (P = .03). As the use of complementary and alternative medicine continues to rise in reproductive-age women, obstetricians will play an integral role in incorporating complementary and alternative medicine use with conventional medicine. © The Author(s) 2016.

Abstract Background Many women use complementary and alternative medicine (CAM). Although CAM use has been associated with reductions in conventionally recommended pediatric preventive care (e.g., vaccination), little is known about associations between CAM use and receipt of recommended preventive screening in women. Methods Using Washington State insurance data from 2000 to 2003, the authors generated clustered logistic regression models, examining associations between provider-based CAM use and receipt of screening tests for Chlamydia trachomatis, breast cancer, and cervical cancer: (1) contrasting women who used CAM providers only (alternative use) and women who used both conventional and CAM providers (complementary use) with women who used conventional care only and (2) testing associations between screening and use of four specific CAM provider types—naturopathic physicians, chiropractors, massage therapists, and acupuncturists. Results Both alternative and complementary use was associated with reduced Chlamydia screening. Cancer screening increased with complementary use but decreased with alternative use of CAM. Use of naturopathy was associated with decreased mammography, whereas all four CAM therapies were positively associated with Papanicolaou testing. Conclusions When used in conjunction with conventional care, use of provider-based CAM may signal high interest in various types of health-promoting behavior, including cancer screening. Negative associations between CAM and Chlamydia screening and between naturopathy and mammography require additional study. Interventions with CAM providers and their patients, aimed at improving rates of conventionally recommended screening, might encourage greater focus on preventive care, an important task when CAM providers serve as women's only contact with the healthcare system.

to use complementary cine EPID and gimbals log file analysis for in-vivo tracking accuracy monitoring. A clinical prototype of dynamic tracking (DT) was installed on the Vero SBRT system. This prototype version allowed tumor tracking by gimballed linac rotations using an internal-external correspondence model. The DT prototype software allowed the detailed logging of all applied gimbals rotations during tracking. The integration of an EPID on the vero system allowed the acquisition of cine EPID images during DT. We quantified the tracking error on cine EPID (E-EPID) by subtracting the target center (fiducial marker detection) and the field centroid. Dynamic gimbals log file information was combined with orthogonal x-ray verification images to calculate the in-vivo tracking error (E-kVLog). The correlation between E-kVLog and E-EPID was calculated for validation of the gimbals log file. Further, we investigated the sensitivity of the log file tracking error by introducing predefined systematic tracking errors. As an application we calculate gimbals log file tracking error for dynamic hidden target tests to investigate gravity effects and decoupled gimbals rotation from gantry rotation. Finally, calculating complementary cine EPID and log file tracking errors evaluated the clinical accuracy of dynamic tracking. A strong correlation was found between log file and cine EPID tracking error distribution during concurrent measurements (R=0.98). We found sensitivity in the gimbals log files to detect a systematic tracking error up to 0.5 mm. Dynamic hidden target tests showed no gravity influence on tracking performance and high degree of decoupled gimbals and gantry rotation during dynamic arc dynamic tracking. A submillimetric agreement between clinical complementary tracking error measurements was found. Redundancy of the internal gimbals log file with x-ray verification images with complementary independent cine EPID images was implemented to monitor the accuracy of

What Learning Systems do Intelligent Agents Need? Complementary Learning Systems Theory Updated.

We update complementary learning systems (CLS) theory, which holds that intelligent agents must possess two learning systems, instantiated in mammalians in neocortex and hippocampus. The first gradually acquires structured knowledge representations while the second quickly learns the specifics of individual experiences. We broaden the role of replay of hippocampal memories in the theory, noting that replay allows goal-dependent weighting of experience statistics. We also address recent challenges to the theory and extend it by showing that recurrent activation of hippocampal traces can support some forms of generalization and that neocortical learning can be rapid for information that is consistent with known structure. Finally, we note the relevance of the theory to the design of artificial intelligent agents, highlighting connections between neuroscience and machine learning. Copyright © 2016 Elsevier Ltd.

An apparatus which enables the simultaneous combination of three complementary imaging techniques, optical imaging, fluorescence imaging, and neutron radiography, is presented. While each individual technique can provide information on certain aspects of the sample and their time evolution, a combination of the three techniques in one setup provides a more complete and consistent data set. The setup can be used in transmission and reflection modes and thus with optically transparent as well as opaque samples. Its capabilities are illustrated with two examples. A polymer hydrogel represents a transparent sample and the diffusion of fluorescent particles into and through this polymermore » matrix is followed. In reflection mode, the absorption of solvent by a nile red-functionalized mesoporous silica powder and the corresponding change in fluorescent signal are studied.« less

[Complementary medicine--Jewish medical ethics].

Katz, Yisrae; Schiff, Elad

In Israel, as in the Western world, the use of different methods of complementary and alternative medicine ICAM) is spreading. CAM raises ethical questions of concern to healthcare providers and to the public: Can physicians recommend a treatment that has no scientific evidence? Should the government include such therapies in the health budget? Can complementary therapists receive protection against lawsuits if their treatment is recognized? The purpose of this article is to present a Jewish perspective on these issues. The fundamental sources that deal with the subject are based on the approach of rabbinic authorities toward unproven medicine, as expressed in the "Mishnah" and "Talmud" (200-500 C.E). The great Jewish scholar who discusses the subject in detail is Maimonides (1135-1204), who defines what "medicine" is and claims that medicine has to rely on reason or experience. Contemporary Jewish commentators present their position based on the interpretation of Maimonides' texts. In this article we claim that treatments can be divided into four groups, each group having a different halachic status: (1) Treatment that might be dangerous--should not be used. (2) Treatment that is safe--can be used, but has no other special status. (3) Treatment recognized by alternative therapists--has consequences for the observant Jew, such as laws of Kashrut and Shabbat. (4) Treatment that was tested and proven using modern medical methods has public significance--the therapist is entitled to legal defense if he made a reasonable mistake; the government can consider funding such treatment using public money. This article presents the Jewish halachic sources upon which we propose an ethical-practical approach to CAM.

This study was conducted to determine the pediatric usage of complementary/alternative medicine (CAM) by parents in Turkey, the incidence of using these methods, and the factors affecting their use. The sectional and relational design of the study included a sample of 497 parents who took children for treatment at the Maternity and Children's Hospital in Giresun, Turkey. Data for the study were collected via the Personal Information Form and the Evaluation Form for Complementary/Alternative Treatment Use. The data collection tools were filled out by the researchers during the face-to-face interviews. Data obtained from the study were analyzed by Pearson chi-square, Fisher-Freeman-Halton and Fisher's exact (posthoc Bonferroni) tests and Z-test. It was determined that 97.7% of the parents had used at least one CAM method. Moreover, the parents had used CAM methods mostly for respiratory complaints. The CAM methods were most commonly used for the symptoms of fever, diarrhea, and cough. It was observed that the most commonly used alternative methods in the past were vitamin/mineral remedies, cold treatments, and hodja (Islamic teacher) consultations, while the most common alternative methods currently used are massage, music, and cold treatment. In addition, the differences found between CAM users in terms of sociodemographic characteristics were not statistically significant. It is crucial for nurses to learn the characteristics of the health/disease treatments used by those with whom they work in order to increase the efficiency of the service they provide. Thus, it was recommended that nurses should be knowledgeable and aware of the benefits/side effects, treatment methods, and contraindications of CAM. © 2017 Wiley Periodicals, Inc.

How model and input uncertainty impact maize yield simulations in West Africa

Crop models are common tools for simulating crop yields and crop production in studies on food security and global change. Various uncertainties however exist, not only in the model design and model parameters, but also and maybe even more important in soil, climate and management input data. We analyze the performance of the point-scale crop model APSIM and the global scale crop model LPJmL with different climate and soil conditions under different agricultural management in the low-input maize-growing areas of Burkina Faso, West Africa. We test the models’ response to different levels of input information from little to detailed information on soil, climate (1961-2000) and agricultural management and compare the models’ ability to represent the observed spatial (between locations) and temporal variability (between years) in crop yields. We found that the resolution of different soil, climate and management information influences the simulated crop yields in both models. However, the difference between models is larger than between input data and larger between simulations with different climate and management information than between simulations with different soil information. The observed spatial variability can be represented well from both models even with little information on soils and management but APSIM simulates a higher variation between single locations than LPJmL. The agreement of simulated and observed temporal variability is lower due to non-climatic factors e.g. investment in agricultural research and development between 1987 and 1991 in Burkina Faso which resulted in a doubling of maize yields. The findings of our study highlight the importance of scale and model choice and show that the most detailed input data does not necessarily improve model performance.

Complementary and alternative medicine for autism spectrum disorders: rationale, safety and efficacy.

Complementary and alternative medicine is widely used for children with autism spectrum disorder, despite uncertainty regarding efficacy. This review describes complementary and alternative practices commonly used among this population, the rationale for the use of each practice, as well as the side-effect profile and evidence for efficacy. The existing evidence base indicates that melatonin can be recommended as a treatment for sleeping disturbances associated with autism spectrum disorder, while secretin can be rejected as an efficacious treatment for broader autistic symptoms. There is insufficient evidence to draw conclusions on the efficacy of modified diets, hyperbaric oxygen therapy, immune therapy, and vitamin and fatty acid supplementation. There is a clear need for methodologically rigorous studies to provide evidence-based guidance to families and clinicians regarding complementary and alternative practices for individuals with autism spectrum disorders. © 2013 The Author.

Promotion and advocacy for improved complementary feeding: can we apply the lessons learned from breastfeeding?

PubMed

Piwoz, Ellen G; Huffman, Sandra L; Quinn, Victoria J

2003-03-01

Although many successes have been achieved in promoting breastfeeding, this has not been the case for complementary feeding. Some successes in promoting complementary feeding at the community level have been documented, but few of these efforts have expanded to a larger scale and become sustained. To discover the reasons for this difference, the key factors for the successful promotion of breastfeeding on a large scale were examined and compared with the efforts made in complementary feeding. These factors include definition and rationale, policy support, funding, advocacy, private-sector involvement, availability and use of monitoring data, integration of research into action, and the existence of a well-articulated series of steps for successful implementation. The lessons learned from the promotion of breastfeeding should be applied to complementary feeding, and the new Global Strategy for Infant and Young Child Feeding provides an excellent first step in this process.

Data on fission yields and isomeric yield ratios (IYR) are tools to study the fission process, in particular the generation of angular momentum. We use the IGISOL facility with the Penning trap JYFLTRAP in Jyväskylä, Finland, for such measurements on 232Th and natU targets. Previously published fission yield data from IGISOL concern the 232Th(p,f) and 238U(p,f) reactions at 25 and 50 MeV. Recently, a neutron source, using the Be(p,n) reaction, has been developed, installed and tested. We summarize the results for (p,f) focusing on the first measurement of IYR by direct ion counting. We also present first results for IYR and relative yields for Sn and Sb isotopes in the 128-133 mass range from natU(n,f) based on γ-spectrometry. We find a staggering behaviour in the cumulative yields for Sn and a shift in the independent fission yields for Sb as compared to current evaluations. Plans for the future experimental program on fission yields and IYR measurements are discussed.

Patient-provider communication about complementary health approaches can support diabetes self-management by minimizing risk and optimizing care. We sought to identify sociodemographic and communication factors associated with disclosure of complementary health approaches to providers by low-income patients with diabetes. We used data from San Francisco Health Plan's SMARTSteps Program, a trial of diabetes self-management support for low-income patients (n=278) through multilingual automated telephone support. Interviews collected use and disclosure of complementary health approaches in the prior month, patient-physician language concordance, and quality of communication. Among racially, linguistically diverse participants, half (47.8%) reported using complementary health practices (n=133), of whom 55.3% disclosed use to providers. Age, sex, race/ethnicity, nativity, education, income, and health literacy were not associated with disclosure. In adjusted analyses, disclosure was associated with language concordance (AOR=2.21, 95% CI: 1.05, 4.67), physicians' interpersonal communication scores (AOR=1.50, 95% CI: 1.03, 2.19), shared decision making (AOR=1.74, 95% CI: 1.33, 2.29), and explanatory-type communication (AOR=1.46, 95% CI: 1.03, 2.09). Safety net patients with diabetes commonly use complementary health approaches and disclose to providers with higher patient-rated quality of communication. Patient-provider language concordance and patient-centered communication can facilitate disclosure of complementary health approaches. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Appropriate infant and young child feeding could reduce morbidity and mortality and could improve cognitive development of children. However, nationwide data on exclusive breastfeeding and complementary feeding status in China are scarce. The aim of this study was to assess current exclusive breastfeeding and complementary feeding status in China. A national representative survey (Chinese National Nutrition and Health Survey) of children aged under 6 years was done in 2013. Stratified multistage cluster sampling was used to select study participants. World Health Organization (WHO) infant and young child feeding indicators were firstly used to assess exclusive breastfeeding and complementary feeding practice nationwide. In total, 14,458 children aged under two years (0 to <730 days) were studied from 55 counties in 30 provinces in China. The crude exclusive breastfeeding rate under 6 months was 20.7% (908/4381) and the weighted exclusive breastfeeding rate was 18.6%. The crude prevalence of minimum dietary diversity, minimum meal frequency and minimum acceptable diet were 52.5% (5286/10,071), 69.8% (7027/10,071), and 27.4% (2764/10,071) among children aged 6-23 months, respectively. The weighted rate was 53.7%, 69.1%, and 25.1%, respectively. Residential area, household income and maternal education were positively associated with the three complementary feeding indicators. The exclusive breastfeeding rate under 6 months was low and complementary feeding practice was not optimal in China. Residential area, household income and maternal education might be used to target infants and young children to improve complementary feeding practice.

The last few decades have seen the rise of alternative medical approaches including the use of herbal supplements, natural products, and traditional medicines, which are collectively known as 'Complementary medicines'. However, there are increasing concerns on the safety and health benefits of these medicines. One of the main hazards with the use of complementary medicines is the presence of heavy metal(loid)s such as arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg). This review deals with the characteristics of complementary medicines in terms of heavy metal(loid)s sources, distribution, bioavailability, toxicity, and human risk assessment. The heavy metal(loid)s in these medicines are derived from uptake by medicinal plants, cross-contamination during processing, and therapeutic input of metal(loid)s. This paper discusses the distribution of heavy metal(loid)s in these medicines, in terms of their nature, concentration, and speciation. The importance of determining bioavailability towards human health risk assessment was emphasized by the need to estimate daily intake of heavy metal(loid)s in complementary medicines. The review ends with selected case studies of heavy metal(loid) toxicity from complementary medicines with specific reference to As, Cd, Pb, and Hg. The future research opportunities mentioned in the conclusion of review will help researchers to explore new avenues, methodologies, and approaches to the issue of heavy metal(loid)s in complementary medicines, thereby generating new regulations and proposing fresh approach towards safe use of these medicines.

Many cancer patients within developed nations cite the media as informing their decisions to use complementary and alternative medicine (CAM). The present study describes (1) Australian newspaper coverage of CAM use for cancer between 1998 and 2007; (2) trends in reporting frequency and characteristics; and (3) how the Australian press framed stories on CAM use for cancer. This study is a content analysis featuring quantitative and qualitative techniques, the latter guided by 'media framing', of targeted newspaper articles. One hundred nineteen articles focused on CAM use for the treatment of cancer were identified. Quantitative analysis found that biologically based CAMs were most frequently described and breast cancer most mentioned. Two thirds of all articles described CAM use in the context of a cure, with approximately half of these opposing this reason for use. Potential benefits of CAM were discussed more frequently than potential risks, and information on costs and how to access CAM were uncommon. Recommendations included advice to use complementary, not alternative therapies, yet advice to discuss CAM with a medical doctor was rare. Qualitative analysis found six CAM cancer-related frames, four in support of CAM use for cancer treatment. The dominant frame constructed CAM as legitimate tools to assist biomedicine (even to cure), with others depicting CAM as normal and necessary or as addressing limitations of biomedicine. Negative frames depicted CAM as questionable and risky practices and the industry/practitioners as possessing malevolent intent. These findings have implications for biomedical practitioners attempting to determine, respect and assist patient choices about their treatment.

Guizhi Fuling capsule (GFC), developed from the traditional Chinese prescription of Guizhi Fuling Wan, has been commonly used for the treatment of primary dysmenorrhea (PD). However, the intervention effective mechanism in vivo has not been well elucidated. In this study, an integrated plasma metabonomic strategy based on RP-UPLC-MS coupled with HILIC-UPLC-MS technique has been developed to investigate the global therapeutic effects and intervention mechanisms of GFC on dysmenorrhea rats induced by oxytocin. The 20 potential biomarkers were identified and primarily related to sphingolipid metabolism, steroid hormone biosynthesis, glycerophospholipid metabolism, amino acid metabolism, lipid metabolism and energy metabolism. The results showed that the GFC has therapeutic effects on rats with dysmenorrhea via the regulation of multiple metabolic pathways. Some new potential biomarkers associated with primary dysmenorrhea such as phenylalanine, tryptophan, taurine, carnitine, betaine, creatine and creatinine have been discovered in this study for the first time. This study provides a metabonomic platform based on RP-UPLC-MS complementary to HILIC-UPLC-MS technique to investigate both nonpolar and polar compounds, so as to get a more comprehensive metabolite information to yield insight into the pathophysiology of PD and assessing the efficacy of GFC on PD rats.

To explore complementary feeding practices and identify potential risk factors associated with inadequate complementary feeding practices in Ghana by using the newly developed WHO infant feeding indicators and data from the nationally representative 2008 Ghana Demographic and Health Survey. The source of data for the analysis was the 2008 Ghana Demographic and Health Survey. Analysis of the factors associated with inadequate complementary feeding, using individual-, household- and community-level determinants, was done by performing multiple logistic regression modelling. Ghana. Children (n 822) aged 6-23 months. The prevalence of the introduction of solid, semi-solid or soft foods among infants aged 6-8 months was 72.6 % (95 % CI 64.6 %, 79.3 %). The proportion of children aged 6-23 months who met the minimum meal frequency and dietary diversity for breast-fed and non-breast-fed children was 46.0 % (95 % CI 42.3 %, 49.9 %) and 51.4 % (95 % CI 47.4 %, 55.3 %) respectively and the prevalence of minimum acceptable diet for breast-fed children was 29.9 % (95 % CI 26.1 %, 34.1 %). Multivariate analysis revealed that children from the other administrative regions were less likely to meet minimum dietary diversity, meal frequency and acceptable diet than those from the Volta region. Household poverty, children whose mothers perceived their size to be smaller than average and children who were delivered at home were significantly less likely to meet the minimum dietary diversity requirement; and children whose mothers did not have any postnatal check-ups were significantly less likely to meet the requirement for minimum acceptable diet. Complementary feeding was significantly lower in infants from illiterate mothers (adjusted OR=3.55; 95 % CI 1.05, 12.02). The prevalence of complementary feeding among children in Ghana is still below the WHO-recommended standard of 90 % coverage.

Despite major advances in understanding the pathophysiology of mitochondrial diseases, clinical management of these conditions remains largely supportive, and no effective treatment is available. We therefore assumed that the burden of disease combined with the lack of adequate treatment leaves open a big market for complementary and alternative medicine use. The objective of this study was to evaluate the use and perceived effectiveness of complementary and alternative medicine in children and adults with genetically proven mitochondrial disease. The reported use was surprisingly high, with 88% of children and 91% of adults having used some kind of complementary and alternative medicine in the last 2 years. Also, the mean cost of these treatments was impressive, being 489/year for children and 359/year for adult patients. Over-the-counter remedies (e.g., food supplements, homeopathy) and self-help techniques (e.g., Reiki, yoga) were the most frequently used complementary and alternative therapies in our cohort: 54% of children and 60% of adults reported the various complementary and alternative medicine therapies to be effective. Given the fact that currently no effective treatment exists, further research toward the different therapies is needed, as our study clearly demonstrates that such therapies are highly sought after by affected patients.

To evaluate the knowledge of public day care centers employees about breastfeeding and complementary feeding. A cross-sectional study was conducted in 15 public day care centers randomly selected in the city of Uberlandia, Southeast Brazil. A questionnaire applied to school principals, teachers, educators and general services assistants (GSA) included demographic and socioeconomic variables and questions about knowledge on breastfeeding, complementary feeding besides employees' perceptions about these subjects. Kruskal-Wallis with multiple comparison and chi-square tests were used to compare variables by professional category. 304 employees participated in the study. The highest percentages of correct answers were noted for questions about exclusive breastfeeding: definition - 97% (n=296) and duration - 65% (n=199). Regarding complementary feeding, 61% (n=187) correctly answered about the appropriate age to introduce it, with a lower percentage for meat (56%; n=170) and sugar (16%; n=50). Concerning employees' perceptions, 9% (n=29) believed that there is weak breast milk, 79% (n=241) and 51% (n=157) reported the negative influence of bottle feeding and pacifier use on breastfeeding. Among the interviewed subjects, 77% (n=234) answered that they had a positive influence on the quality of the food given to the children. There were no differences in the answers according to professional category, except for the negative influence of pacifiers on breastfeeding. Employees of public day care centers knew more about breastfeeding than about complementary feeding. Educational activities about breastfeeding and complementary feeding are necessary for day care centers employees.

2017-12-01

Mountainous regions are increasingly vulnerable to food insecurity because of limited arable land, growing population pressure, and climate change. Development of sustainable mountain agriculture will require an increased understanding of the effects of environmental factors on grain and climatic yields. The objective of this study was to explore the relationships between actual grain yield, climatic yield, and environmental factors in a mountainous region in China. We collected data on the average grain yield per unit area in 119 counties in Yunnan province from 1985 to 2012, and chose 17 environmental factors for the same period. Our results showed that actual grain yield ranged from 1.43 to 6.92 t·ha-1, and the climatic yield ranged from -0.15 to -0.01 t·ha-1. Lower climatic yield but higher grain yield was generally found in central areas and at lower slopes and elevations in the western and southwestern counties of Yunnan province. Higher climatic yield but lower grain yield were found in northwestern parts of Yunnan province on steep slopes. Annual precipation and temperature had a weak influence on the climatic yield. Slope explained 44.62 and 26.29% of the variation in grain yield and climatic yield. The effects of topography on grain and climatic yields were greater than climatic factors. Slope was the most important environmental variable for the variability in climatic and grain yields in the mountainous Yunnan province due to the highly heterogeneous topographic conditions. Conversion of slopes to terraces in areas with higher climatic yields is an effective way to maintain grain production in response to climate variability. Additionally, soil amendments and soil and water conservation measures should be considered to maintain soil fertility and aid in sustainable development in central areas, and in counties at lower slopes and elevations in western and southwestern Yunnan province.

Childhood malnutrition is a common disorder in developing countries. To formulate a complementary food from rice, germinated-decoated faba bean, orange-fleshed sweet potato flour, and peanut oil (RFPP formula) for infants aged 6 to 24 months. The nutritional and sensory characteristics of the RFPP complementary food in comparison with those of a commercial complementary food were determined using standard official procedures. The levels of protein (17.89 g/100 g), fat (10.35 g/100 g), carbohydrate (67.82 g/100 g), and energy (435.99 kcal/100 g) of the RFPP complementary food met the specifications of the Codex standard (1991) and the Egyptian Standard No. 3284 (2005). The essential amino acid contents of the RFPP complementary food were higher than the amino acid profile of the Food and Agriculture Organization/World Health Organization/United Nations University (2002) reference protein for children 0.5 to 1 and 1 to 2 years of age. The RFPP complementary food had high levels (54.00%) of monounsaturated fatty acids. However, the highest level of saturated fatty acids (51.10%) was recorded for the commercial complementary food. The sensory evaluation results, using a nine-point hedonic scale ranging from 1 (dislike extremely) to 9 (like extremely), show that the RFPP complementary food was acceptable in appearance (7.20), color (6.35), aroma (6.75), taste (7.25), and mouthfeel (7.10) and had an overall acceptability of 6.40. The RFPP formulated complementary food was acceptable and adequate in nutrients for weaning purposes.

This study aimed to analyze the inclusion of Traditional and Complementary Medicine in Brazilian Unified National Health System (SUS) and its integration with primary healthcare (PHC). A qualitative study drew on institutional data, indexed articles, and case studies in selected Brazilian cities: Campinas (São Paulo State), Florianópolis (Santa Catarina State), Recife (Pernambuco State), Rio de Janeiro, and São Paulo. The analysis adopted the perspective of inclusion of Traditional and Complementary Medicine in the healthcare network and its integration with primary healthcare, based on the following dimensions: presence of Traditional and Complementary Medicine on the municipal agenda; position in the services; mode of access to Traditional and Complementary Medicine; Traditional and Complementary Medicine practitioners; types of practices; demand profile; and potential for expansion in the SUS. The authors identified and characterized four types of inclusion and integration of Traditional and Complementary Medicine, whether in association or not: Type 1 - in primary healthcare via professionals from the family health teams - Integrated; Type 2 - in primary healthcare via professionals with full-time employment - Juxtaposed; Type 3 - in primary healthcare via matrix-organized teams - Matrix Organization; Type 4 - in specialized services - Without Integration. The combination of types 1 and 3 was considered a potential guideline for the expansion of Traditional and Complementary Medicine in the SUS and can orient the growth and integration of Traditional and Complementary Medicine with primary healthcare. The growing presence of Traditional and Complementary Medicine in the SUS requires conceiving its strategic expansion, while existing experiences should not be wasted.

Increasing grain yield is a long-term goal in crop breeding to meet the demand for global food security. Heterosis, when a hybrid shows higher performance for a trait than both parents, offers an important strategy for crop breeding. To examine the genetic basis of heterosis for yield in rice, here we generate, sequence and record the phenotypes of 10,074 F 2 lines from 17 representative hybrid rice crosses. We classify modern hybrid rice varieties into three groups, representing different hybrid breeding systems. Although we do not find any heterosis-associated loci shared across all lines, within each group, a small number of genomic loci from female parents explain a large proportion of the yield advantage of hybrids over their male parents. For some of these loci, we find support for partial dominance of heterozygous locus for yield-related traits and better-parent heterosis for overall performance when all of the grain-yield traits are considered together. These results inform on the genomic architecture of heterosis and rice hybrid breeding.

Kinetically accessible yield (KAY) for redirection of metabolism to produce exo-metabolites

DOE PAGES

Lafontaine Rivera, Jimmy G.; Theisen, Matthew K.; Chen, Po-Wei; ...

2017-04-05

The product formation yield (product formed per unit substrate consumed) is often the most important performance indicator in metabolic engineering. Until now, the actual yield cannot be predicted, but it can be bounded by its maximum theoretical value. The maximum theoretical yield is calculated by considering the stoichiometry of the pathways and cofactor regeneration involved. Here in this paper we found that in many cases, dynamic stability becomes an issue when excessive pathway flux is drawn to a product. This constraint reduces the yield and renders the maximal theoretical yield too loose to be predictive. We propose a more realisticmore » quantity, defined as the kinetically accessible yield (KAY) to predict the maximum accessible yield for a given flux alteration. KAY is either determined by the point of instability, beyond which steady states become unstable and disappear, or a local maximum before becoming unstable. Thus, KAY is the maximum flux that can be redirected for a given metabolic engineering strategy without losing stability. Strictly speaking, calculation of KAY requires complete kinetic information. With limited or no kinetic information, an Ensemble Modeling strategy can be used to determine a range of likely values for KAY, including an average prediction. We first apply the KAY concept with a toy model to demonstrate the principle of kinetic limitations on yield. We then used a full-scale E. coli model (193 reactions, 153 metabolites) and this approach was successful in E. coli for predicting production of isobutanol: the calculated KAY values are consistent with experimental data for three genotypes previously published.« less

Estimating yield gaps at the cropping system level.

2017-05-01

Yield gap analyses of individual crops have been used to estimate opportunities for increasing crop production at local to global scales, thus providing information crucial to food security. However, increases in crop production can also be achieved by improving cropping system yield through modification of spatial and temporal arrangement of individual crops. In this paper we define the cropping system yield potential as the output from the combination of crops that gives the highest energy yield per unit of land and time, and the cropping system yield gap as the difference between actual energy yield of an existing cropping system and the cropping system yield potential. Then, we provide a framework to identify alternative cropping systems which can be evaluated against the current ones. A proof-of-concept is provided with irrigated rice-maize systems at four locations in Bangladesh that represent a range of climatic conditions in that country. The proposed framework identified (i) realistic alternative cropping systems at each location, and (ii) two locations where expected improvements in crop production from changes in cropping intensity (number of crops per year) were 43% to 64% higher than from improving the management of individual crops within the current cropping systems. The proposed framework provides a tool to help assess food production capacity of new systems ( e.g. with increased cropping intensity) arising from climate change, and assess resource requirements (water and N) and associated environmental footprint per unit of land and production of these new systems. By expanding yield gap analysis from individual crops to the cropping system level and applying it to new systems, this framework could also be helpful to bridge the gap between yield gap analysis and cropping/farming system design.

The New Hampshire Bedrock Aquifer Assessment was designed to provide information that can be used by communities, industry, professional consultants, and other interests to evaluate the ground-water development potential of the fractured-bedrock aquifer in the State. The assessment was done at statewide, regional, and well field scales to identify relations that potentially could increase the success in locating high-yield water supplies in the fractured-bedrock aquifer. statewide, data were collected for well construction and yield information, bedrock lithology, surficial geology, lineaments, topography, and various derivatives of these basic data sets. Regionally, geologic, fracture, and lineament data were collected for the Pinardville and Windham quadrangles in New Hampshire. The regional scale of the study examined the degree to which predictive well-yield relations, developed as part of the statewide reconnaissance investigation, could be improved by use of quadrangle-scale geologic mapping. Beginning in 1984, water-well contractors in the State were required to report detailed information on newly constructed wells to the New Hampshire Department of Environmental Services (NHDES). The reports contain basic data on well construction, including six characteristics used in this study?well yield, well depth, well use, method of construction, date drilled, and depth to bedrock (or length of casing). The NHDES has determined accurate georeferenced locations for more than 20,000 wells reported since 1984. The availability of this large data set provided an opportunity for a statistical analysis of bedrock-well yields. Well yields in the database ranged from zero to greater than 500 gallons per minute (gal/min). Multivariate regression was used as the primary statistical method of analysis because it is the most efficient tool for predicting a single variable with many potentially independent variables. The dependent variable that was explored in this study was the

Affordable, locally contextual complementary feeding recommendations (CFRs) that take into account cultural diversity and differences in food availability will be more likely to result in long-term improvements in complementary feeding practices than general recommendations. More objective approaches, such as linear programming (LP), have been recommended to identify optimal but CFRs to meet nutrient requirements given local food availability, food patterns, food portions, and cost. To present results of our previous studies in which we developed CFRs using LP and to provide an example of how these CFRs can be put into practice in a community intervention trial in Indonesia. Dietary data were obtained using single 24-hour dietary recall or 1-day weighed diet record combined with 1-day 24-hour recall and 5-day food intake tally. With the use of the LP approach, nutrient intakes were optimized while ensuring that a realistic diet was selected by using constraints such as the diet's energy content, food patterns, food portions, and cost. The price per 100 g of edible portion was obtained from market surveys in two or three local markets in each study area. LP analysis was performed using Super Solver in MS Excel or Optifood software. Iron, zinc, calcium, and niacin were problem nutrients in all age groups of children (6 to 8, 9 to 11, and 12 to 23 months) in both rural and periurban areas, except among children of higher socioeconomic status in urban areas. Thiamin and folate were also problem nutrients found in some settings. Animal-source foods (meat, fish, poultry, and eggs [MFPE] and fortified foods were the nutrient-dense foods identified by LP to fill the nutrient gaps of these problem nutrients. Iron, calcium, zinc, niacin, and potentially folate and thiamine are typical "problem nutrients" in complementary foods of Indonesian children. However, the extent of dietary inadequacy varies across age groups, area, and socioeconomic level. MFPE and fortified foods

Human activity causes abrupt changes in resource availability across the landscape. In order to persist in human-altered landscapes organisms need to shift their habitat use accordingly. Little is known about the mechanisms by which whole communities persist in human-altered landscapes, including the role of complementary habitat use. We define complementary habitat use as the use of different habitats at different times by the same group of species during the course of their activity period. We hypothesize that complementary habitat use is a mechanism through which native bee species persist in human-altered landscapes. To test this idea, we studied wild bee communities in agro-natural landscapes and explored their community-level patterns of habitat and resource use over space and time. The study was conducted in six agro-natural landscapes in the eastern United States, each containing three main bee habitat types (natural habitat, agricultural fields, and old fields). Each of the three habitats exhibited a unique seasonal pattern in amount, diversity, and composition of floral resources, and together they created phenological complementarity in foraging resources for bees. Individual bee species as well as the bee community responded to these spatiotemporal patterns in floral availability and exhibited a parallel pattern of complementary habitat use. The majority of wild bee species, including all the main crop visitors, used fallow areas within crops early in the season, shifted to crops in mid-season, and used old-field habitats later in the season. The natural-forest habitat supported very limited number of bees, mostly visitors of non-crop plants. Old fields are thus an important feature in these arable landscapes for maintaining crop pollination services. Our study provides a detailed examination of how shifts in habitat and resource use may enable bees to persist in highly dynamic agro-natural landscapes, and points to the need for a broad cross

How visual illusions illuminate complementary brain processes: illusory depth from brightness and apparent motion of illusory contours

PubMed Central

Grossberg, Stephen

2014-01-01

Neural models of perception clarify how visual illusions arise from adaptive neural processes. Illusions also provide important insights into how adaptive neural processes work. This article focuses on two illusions that illustrate a fundamental property of global brain organization; namely, that advanced brains are organized into parallel cortical processing streams with computationally complementary properties. That is, in order to process certain combinations of properties, each cortical stream cannot process complementary properties. Interactions between these streams, across multiple processing stages, overcome their complementary deficiencies to compute effective representations of the world, and to thereby achieve the property of complementary consistency. The two illusions concern how illusory depth can vary with brightness, and how apparent motion of illusory contours can occur. Illusory depth from brightness arises from the complementary properties of boundary and surface processes, notably boundary completion and surface-filling in, within the parvocellular form processing cortical stream. This illusion depends upon how surface contour signals from the V2 thin stripes to the V2 interstripes ensure complementary consistency of a unified boundary/surface percept. Apparent motion of illusory contours arises from the complementary properties of form and motion processes across the parvocellular and magnocellular cortical processing streams. This illusion depends upon how illusory contours help to complete boundary representations for object recognition, how apparent motion signals can help to form continuous trajectories for target tracking and prediction, and how formotion interactions from V2-to-MT enable completed object representations to be continuously tracked even when they move behind intermittently occluding objects through time.

The model is the conceptual basis for CAM health literacy, which is operationally defined as the information about CAM needed to make informed self-management decisions regarding health. Improving health literacy is a national priority, and widespread use of CAM has added to the complexity of this task. There are no currently available models or measures of health literacy regarding CAM. The authors developed the model using an iterative process of deriving concepts, constructs, and empirical indicators from the literature and the author’s prior work, review and critique by experts, and revision. The model of CAM health literacy can serve as the basis for future research on the use and efficacy of CAM and the constructs and concepts within it can be used to identify points of intervention for research or for clinical practice. It is anticipated that the model will have scientific and clinical application for assessing health literacy in other self care decision-making situations. PMID:23889542

Acute upper and lower gastrointestinal bleeding, enteral feeding, cecostomy tubes and luminal strictures are some of the common reasons for gastroenterology service. While surgery was initially considered the main treatment modality, the advent of both therapeutic endoscopy and interventional radiology have resulted in the paradigm shift in the management of these conditions. In this paper, we discuss the patient’s work up, indications, and complementary roles of endoscopic and angiographic management in the settings of gastrointestinal bleeding, enteral feeding, cecostomy tube placement and luminal strictures. These conditions often require multidisciplinary approaches involving a team of interventional radiologists, gastroenterologists and surgeons. Further, the authors also aim to describe how the fields of interventional radiology and gastrointestinal endoscopy are overlapping and complementary in the management of these complex conditions.

The plant DNA virus African cassava mosaic virus (ACMV) is believed to replicate by a rolling circle mechanism. To investigate complementary-sense DNA (lagging strand) synthesis, we have analysed the heterogenous form of complementary-sense DNA (H3 DNA) from infected Nicotiana benthamiana by two-dimensional agarose gel electrophoresis and blot hybridisation. The presence of an RNA moeity is demonstrated by comparison of results for nucleic acids resolved on neutral/alkaline and neutral/formamide gels, suggesting that complementary-sense DNA synthesis on the virus-sense single-stranded DNA template is preceded by the synthesis of an RNA primer. Hybridisation with probes to specific parts of ACMV DNA A genome indicates that synthesis of the putative RNA primer initiates between nucleotides 2581-221, a region that includes intergenic sequences that have been implicated in geminivirus DNA replication and the control of gene expression.

Berry weight, berry number and cluster weight are key parameters for yield estimation for wine and tablegrape industry. Current yield prediction methods are destructive, labour-demanding and time-consuming. In this work, a new methodology, based on image analysis was developed to determine cluster yield components in a fast and inexpensive way. Clusters of seven different red varieties of grapevine (Vitis vinifera L.) were photographed under laboratory conditions and their cluster yield components manually determined after image acquisition. Two algorithms based on the Canny and the logarithmic image processing approaches were tested to find the contours of the berries in the images prior to berry detection performed by means of the Hough Transform. Results were obtained in two ways: by analysing either a single image of the cluster or using four images per cluster from different orientations. The best results (R(2) between 69% and 95% in berry detection and between 65% and 97% in cluster weight estimation) were achieved using four images and the Canny algorithm. The model's capability based on image analysis to predict berry weight was 84%. The new and low-cost methodology presented here enabled the assessment of cluster yield components, saving time and providing inexpensive information in comparison with current manual methods. © 2014 Society of Chemical Industry.

OBJECTIVE: To evaluate the knowledge of public day care centers employees about breastfeeding and complementary feeding. METHODS: A cross-sectional study was conducted in 15 public day care centers randomly selected in the city of Uberlandia, Southeast Brazil. A questionnaire applied to school principals, teachers, educators and general services assistants (GSA) included demographic and socioeconomic variables and questions about knowledge on breastfeeding, complementary feeding besides employees' perceptions about these subjects. Kruskal-Wallis with multiple comparison and chi-square tests were used to compare variables by professional category. RESULTS: 304 employees participated in the study. The highest percentages of correct answers were noted for questions about exclusive breastfeeding: definition - 97% (n=296) and duration - 65% (n=199). Regarding complementary feeding, 61% (n=187) correctly answered about the appropriate age to introduce it, with a lower percentage for meat (56%; n=170) and sugar (16%; n=50). Concerning employees' perceptions, 9% (n=29) believed that there is weak breast milk, 79% (n=241) and 51% (n=157) reported the negative influence of bottle feeding and pacifier use on breastfeeding. Among the interviewed subjects, 77% (n=234) answered that they had a positive influence on the quality of the food given to the children. There were no differences in the answers according to professional category, except for the negative influence of pacifiers on breastfeeding. CONCLUSIONS: Employees of public day care centers knew more about breastfeeding than about complementary feeding. Educational activities about breastfeeding and complementary feeding are necessary for day care centers employees. PMID:24473953

Complementary and Alternative Medicine Use and Symptom Burden in Women Undergoing Chemotherapy for Breast Cancer in Malaysia.

Chui, Ping Lei; Abdullah, Khatijah Lim; Wong, Li Ping; Taib, Nur Aishah

Complementary and alternative medicine (CAM) is commonly used for cancer- and chemotherapy-related symptoms. Nurses are likely to encounter many CAM users in their practice. The aims of this study were to assess CAM use and examine the symptom burden of CAM and non-CAM users among patients with breast cancer who are undergoing chemotherapy. A CAM use questionnaire and the Side-Effect Burden Scale were administered to 546 patients. Complementary and alternative medicine use was categorized as mind-body practices (MBPs), natural products (NPs), or traditional medicine (TM). We identified 386 CAM users (70.7%) in this study. The CAM users reported a higher marginal mean total symptom burden score (40.39 ± 2.6) than non-CAM users (36.93 ± 3.21), although this difference was not statistically significant (P = .09). Triple-modality (MBP-NP-TM) CAM users had a significantly higher marginal mean total symptom burden score (47.44 ± 4.12) than single-modality (MBP) users (34.09 ± 4.43). The risk of having a high total symptom burden score was 12.9-fold higher among the MBP-NP-TM users than among the MBP users. Complementary and alternative medicine use is common among Malaysian patients who are undergoing chemotherapy for breast cancer. However, CAM and non-CAM users reported similar symptom burdens, although single-modality use of MBP is likely associated with a lower symptom burden. Nurses should keep abreast of current developments and trends in CAM use. Understanding CAM use and the related symptom burden will allow nurses to initiate open discussion and guide their patients in seeking additional information or referrals for a particular therapy.

We demonstrate a nanocrystal (NC)-based complementary inverter constructed on a flexible plastic substrate. The NC-based complementary inverter consists of n-type HgSe NC- and p-type HgTe NC-based thin-film transistors (TFTs). Solid films on a plastic substrate obtained from HgSe and HgTe nanocrystals by thermal transformation are utilized as the n- and p-channel layers in these TFTs, respectively. The electrical properties of these component TFTs on unstrained and strained substrates are characterized and the performance of the inverter on the flexible substrate is investigated. The inverter on the unstrained substrate exhibits a logic gain of about 8, a logic swing of 90%, and a noise margin of 2.0 V. The characteristics of the inverter are changed under tensile and compressive strains, but not very significantly. Moreover, a comparison of the electrical characteristics of the n- and p-channel TFTs and the inverter is made in this paper.

Complementary alternative medicine (CAM) is widely used among patients with cancer. This usage may have potentially harmful effects, especially when combined with anticancer drugs. However, some complementary methods may benefit patients. This review investigated the prevalence of CAM use among patients with cancer in Scandinavia and secondly studied the educational levels of CAM users compared to non-users. A systematic search of the PubMed library was carried out to locate articles published between January 2000 and October 2015 that investigated prevalence of CAM use among Scandinavian patients with cancer. Twenty-two articles were found, of which nine were included in the review. The prevalence of CAM use was 7.9% to 53%, with an average of 36.0% across all studies. Use of CAM is widespread among patients with cancer. Knowledge about CAM should be disseminated to both patients and staff in order to optimise discussions about CAM in clinical practice.

Use of complementary and alternative medicines by a sample of Turkish women for infertility enhancement: a descriptive study

PubMed Central

2010-01-01

Background Infertility patients are a vulnerable group that often seeks a non-medical solution for their failure to conceive. World-wide, women use CAM for productive health, but only a limited number of studies report on CAM use to enhance fertility. Little is known about traditional and religious forms of therapies that are used in relation to conventional medicine in Turkey. We investigated the prevalence and types of complementary and alternative medicine (CAM) used by infertile Turkish women for fertility enhancement. Methods A face-to-face questionnaire inquiring demographic information and types of CAM used for fertility enhancement were completed by hundred infertility patients admitted to a primary care family planning centre in Van, Turkey between January and July 2009. Results The vast majority of infertile women had used CAM at least once for infertility. CAM use included religious interventions, herbal products and recommendations of traditional "hodja's" (faith healers). Of these women, 87.8% were abused in the last 12 months, 36.6% felt not being supported by her partner and 80.5% had never spoken with a physician about CAM. Conclusions Infertile Turkish women use complementary medicine frequently for fertility enhancement and are in need of information about CAM. Religious and traditional therapies are used as an adjunct to, rather than a substitute for, conventional medical therapy. Physicians need to approach fertility patients with sensitivity and should be able to council their patients about CAM accordingly. PMID:20307291

Complementary and alternative medicine services in the United States are an approximately $9 billion market each year, equal to 3 percent of national ambulatory health care expenditures. Unlike conventional allopathic health care, complementary and alternative medicine is primarily paid for out of pocket, although some services are covered by most health insurance. Examining trends in demand for complementary and alternative medicine services in the United States reported in the Medical Expenditure Panel Survey during 2002–08, we found that use of and spending on these services, previously on the rise, have largely plateaued. The higher proportion of out-of-pocket responsibility for payment for services may explain the lack of growth. Our findings suggest that any attempt to reduce national health care spending by eliminating coverage for complementary and alternative medicine would have little impact at best. Should some forms of complementary and alternative medicine—for example, chiropractic care for back pain—be proven more efficient than allopathic and specialty medicine, the inclusion of complementary and alternative medicine providers in new delivery systems such as accountable care organizations could help slow growth in national health care spending.

Grain-yield prediction using remotely sensed data have been intensively studied in wheat and maize, but such information is limited in rice, barley, oats and soybeans. The present study proposes a new framework for rice-yield prediction, which eliminates the influence of the technology development, fertilizer application, and management improvement and can be used for the development and implementation of provincial rice-yield predictions. The technique requires the collection of remotely sensed data over an adequate time frame and a corresponding record of the region's crop yields. Longer normalized-difference-vegetation-index (NDVI) time series are preferable to shorter ones for the purposes of rice-yield prediction because the well-contrasted seasons in a longer time series provide the opportunity to build regression models with a wide application range. A regression analysis of the yield versus the year indicated an annual gain in the rice yield of 50 to 128 kg ha(-1). Stepwise regression models for the remotely sensed rice-yield predictions have been developed for five typical rice-growing provinces in China. The prediction models for the remotely sensed rice yield indicated that the influences of the NDVIs on the rice yield were always positive. The association between the predicted and observed rice yields was highly significant without obvious outliers from 1982 to 2004. Independent validation found that the overall relative error is approximately 5.82%, and a majority of the relative errors were less than 5% in 2005 and 2006, depending on the study area. The proposed models can be used in an operational context to predict rice yields at the provincial level in China. The methodologies described in the present paper can be applied to any crop for which a sufficient time series of NDVI data and the corresponding historical yield information are available, as long as the historical yield increases significantly.

Modern cultural trends are inclined to recognise to all human beings an always more ample right to become involved directly in choices affecting them. This even when health is concerned thus requiring expertise not always accessible to all. Informed consent to often gets reduced to a mere formality, having a mostly defensive purpose for the physician. Patients' education is becoming an ever more pressing issue in order to safeguard decision rights and the effective knowledge of the implications of every decision simultaneously. Patients' education has serious ethical implications which can't be eluded nor referred outside as happens when we let mass media inform on the advantages and disadvantages of various therapies. One of the major fields were this misinformed choice right is expressed is the so called complementary and alternative medicine. Nowadays physicians have to get back their therapeutical leadership once again, with renewed responsibility and through education as well. Information as such is a necessary and not sufficient condition. A sheer education involving the physician in a deeper as well as in an extended therapeutical alliance is needed. The challenge of taking care involves the whole human being: his/her sick body, his/her wounded feelings as well as intelligence which has to understand what is happening clearly.

Traditional, complementary, and alternative medicine (TCAM) has been used by some people living with HIV (PLHIV) in an attempt to cure HIV. This article reviews the main factors influencing their decision to choose TCAM to cure HIV and discusses implications for HIV cure research. Those who decide to pursue traditional, complementary, and alternative medical cures may be influenced by the health system, cultural, and social dynamics, and their own individual beliefs and preferences. These same factors may impact participation in HIV cure research. People who search for traditional, complementary, and alternative medical cures may face special challenges as they are recruited, consented, and retained within HIV cure research studies. To address these potential challenges, we have suggested solutions focusing on culturally tailored communication and education, formative social science research, and community partnerships with key stakeholders. The social conditions that have promoted traditional, complementary and alternative medical cures will likely impact how PLHIV participate and experience HIV remission trials. Despite the potential challenges, it will be crucial to involve those who have previously sought out traditional cures for HIV in HIV cure research.

The stay-green phenomenon is a key plant trait with wide usage in managing crop production under limited water conditions. This trait enhances delayed senescence, biomass, and grain yield under drought stress. In this study we sought to identify QTLs in cowpea (Vigna unguiculata) consistent across experiments conducted in Burkina Faso, Nigeria, Senegal, and the United States of America under limited water conditions. A panel of 383 diverse cowpea accessions and a recombinant inbred line population (RIL) were SNP genotyped using an Illumina 1536 GoldenGate assay. Phenotypic data from thirteen experiments conducted across the four countries were used to identify SNP-trait associations based on linkage disequilibrium association mapping, with bi-parental QTL mapping as a complementary strategy. We identified seven loci, five of which exhibited evidence suggesting pleiotropic effects (stay-green) between delayed senescence, biomass, and grain yield. Further, we provide evidence suggesting the existence of positive pleiotropy in cowpea based on positively correlated mean phenotypic values (0.34< r <0.87) and allele effects (0.07< r <0.86) for delayed senescence and grain yield across three African environments. Three of the five putative stay-green QTLs, Dro-1, 3, and 7 were identified in both RILs and diverse germplasm with resolutions of 3.2 cM or less for each of the three loci, suggesting that these may be valuable targets for marker-assisted breeding in cowpea. Also, the co-location of early vegetative delayed senescence with biomass and grain yield QTLs suggests the possibility of using delayed senescence at the seedling stage as a rapid screening tool for post-flowering drought tolerance in cowpea breeding. BLAST analysis using EST sequences harboring SNPs with the highest associations provided a genomic context for loci identified in this study in closely related common bean (Phaseolus vulgaris) and soybean (Glycine max) reference genomes.

Observation techniques with high spatial and temporal resolution, such as single-particle tracking based on interferometric scattering (iSCAT) microscopy, and fluorescence correlation spectroscopy applied on a super-resolution STED microscope (STED-FCS), have revealed new insights of the molecular organization of membranes. While delivering complementary information, there are still distinct differences between these techniques, most prominently the use of fluorescent dye tagged probes for STED-FCS and a need for larger scattering gold nanoparticle tags for iSCAT. In this work, we have used lipid analogues tagged with a hybrid fluorescent tag–gold nanoparticle construct, to directly compare the results from STED-FCS and iSCAT measurements of phospholipid diffusion on a homogeneous supported lipid bilayer (SLB). These comparative measurements showed that while the mode of diffusion remained free, at least at the spatial (>40 nm) and temporal (50  ⩽  t  ⩽  100 ms) scales probed, the diffussion coefficient was reduced by 20- to 60-fold when tagging with 20 and 40 nm large gold particles as compared to when using dye tagged lipid analogues. These FCS measurements of hybrid fluorescent tag–gold nanoparticle labeled lipids also revealed that commercially supplied streptavidin-coated gold nanoparticles contain large quantities of free streptavidin. Finally, the values of apparent diffusion coefficients obtained by STED-FCS and iSCAT differed by a factor of 2–3 across the techniques, while relative differences in mobility between different species of lipid analogues considered were identical in both approaches. In conclusion, our experiments reveal that large and potentially cross-linking scattering tags introduce a significant slow-down in diffusion on SLBs but no additional bias, and our labeling approach creates a new way of exploiting complementary information from STED-FCS and iSCAT measurements.

Although there has been inconsistency in recommendations regarding the optimal time for introducing complementary foods, most experts agree that introduction should not occur before 4 months. Despite recommendations, studies suggest that 20% to 40% of US infants are introduced to foods at younger than 4 months. Previous studies focused on the introduction of solid foods and are not nationally representative. Our aims were to provide a nationally representative estimate of the timing of introduction of complementary foods and to describe predictors of early (<4 months) introduction. We conducted a cross-sectional analysis of 2009-2014 National Health and Nutrition Examination Survey data. The study included 1,482 children aged 6 to 36 months. Timing of first introduction to complementary foods (anything other than breast milk or formula) was analyzed. Prevalence estimates of first introduction to complementary foods are presented by month. Logistic regression was used to assess characteristics associated with early (<4 months) introduction. In this sample, 16.3% of US infants were introduced to complementary foods at <4 months, 38.3% between 4 and <6 months, 32.5% between 6 and <7 months, and 12.9% at ≥7 months of age. In unadjusted analyses, early introduction varied by breastfeeding status; race/Hispanic origin; Special Supplemental Nutrition Program for Women, Infants, and Children participation; and maternal age. In adjusted analyses, only breastfeeding status remained significant; infants who never breastfed or stopped at <4 months were more likely (odds ratio 2.27; 95% CI 1.62 to 3.18) to be introduced to complementary foods early than infants who breastfed ≥4 months. Despite using a broader definition of complementary foods, this analysis found a lower prevalence of early introduction in this nationally representative sample than previous studies that included only solids. However, many young children were still introduced to complementary foods earlier

Root foraging elicits niche complementarity-dependent yield advantage in the ancient ‘three sisters’ (maize/bean/squash) polyculture

Background and Aims Since ancient times in the Americas, maize, bean and squash have been grown together in a polyculture known as the ‘three sisters’. This polyculture and its maize/bean variant have greater yield than component monocultures on a land-equivalent basis. This study shows that below-ground niche complementarity may contribute to this yield advantage. Methods Monocultures and polycultures of maize, bean and squash were grown in two seasons in field plots differing in nitrogen (N) and phosphorus (P) availability. Root growth patterns of individual crops and entire polycultures were determined using a modified DNA-based technique to discriminate roots of different species. Key Results The maize/bean/squash and maize/bean polycultures had greater yield and biomass production on a land-equivalent basis than the monocultures. Increased biomass production was largely caused by a complementarity effect rather than a selection effect. The differences in root crown architecture and vertical root distribution among the components of the ‘three sisters’ suggest that these species have different, possibly complementary, nutrient foraging strategies. Maize foraged relatively shallower, common bean explored the vertical soil profile more equally, while the root placement of squash depended on P availability. The density of lateral root branching was significantly greater for all species in the polycultures than in the monocultures. Conclusions It is concluded that species differences in root foraging strategies increase total soil exploration, with consequent positive effects on the growth and yield of these ancient polycultures.

We sought to construct and partially characterize complementary DNA (cDNA) libraries prepared from the middle ear mucosa (MEM) of chinchillas to better understand pathogenic aspects of infection and inflammation, particularly with respect to leukotriene biogenesis and response. Chinchilla MEM was harvested from controls and after middle ear inoculation with nontypeable Haemophilus influenzae. RNA was extracted to generate cDNA libraries. Randomly selected clones were subjected to sequence analysis to characterize the libraries and to provide DNA sequence for phylogenetic analyses. Reverse transcription-polymerase chain reaction of the RNA pools was used to generate cDNA sequences corresponding to genes associated with leukotriene biosynthesis and metabolism. Sequence analysis of 921 randomly selected clones from the uninfected MEM cDNA library produced approximately 250,000 nucleotides of almost entirely novel sequence data. Searches of the GenBank database with the Basic Local Alignment Search Tool provided for identification of 515 unique genes expressed in the MEM and not previously described in chinchillas. In almost all cases, the chinchilla cDNA sequences displayed much greater homology to human or other primate genes than with rodent species. Genes associated with leukotriene metabolism were present in both normal and infected MEM. Based on both phylogenetic comparisons and gene expression similarities with humans, chinchilla MEM appears to be an excellent model for the study of middle ear inflammation and infection. The higher degree of sequence similarity between chinchillas and humans compared to chinchillas and rodents was unexpected. The cDNA libraries from normal and infected chinchilla MEM will serve as useful molecular tools in the study of otitis media and should yield important information with respect to middle ear pathogenesis.

An Attitude Heading Reference System (AHRS) provides 3D orientation of an aircraft (roll, pitch, and yaw) with instantaneous position and also heading information. For implementation of a low cost AHRS system Micro-electrical-Mechanical system (MEMS) based sensors are used such as accelerometer, gyroscope, and magnetometer. Accelerometers suffer from errors caused by external accelerations that sums to gravity and make accelerometers based rotation inaccurate. Gyroscopes can remove such errors but create drifting problems. So for getting the precise data additionally two very common and well known filters Complementary and Kalman are introduced to the system. In this paper a comparison of system performance using these two filters is shown separately so that one would be able to select filter with better performance for his/her system.
