Functional recovery of secondary tropical forests.

One-third of all Neotropical forests are secondary forests that regrow naturally after agricultural use through secondary succession. We need to understand better how and why succession varies across environmental gradients and broad geographic scales. Here, we analyze functional recovery using community data on seven plant characteristics (traits) of 1,016 forest plots from 30 chronosequence sites across the Neotropics. By analyzing communities in terms of their traits, we enhance understanding of the mechanisms of succession, assess ecosystem recovery, and use these insights to propose successful forest restoration strategies. Wet and dry forests diverged markedly for several traits that increase growth rate in wet forests but come at the expense of reduced drought tolerance, delay, or avoidance, which is important in seasonally dry forests. Dry and wet forests showed different successional pathways for several traits. In dry forests, species turnover is driven by drought tolerance traits that are important early in succession and in wet forests by shade tolerance traits that are important later in succession. In both forests, deciduous and compound-leaved trees decreased with forest age, probably because microclimatic conditions became less hot and dry. Our results suggest that climatic water availability drives functional recovery by influencing the start and trajectory of succession, resulting in a convergence of community trait values with forest age when vegetation cover builds up. Within plots, the range in functional trait values increased with age. Based on the observed successional trait changes, we indicate the consequences for carbon and nutrient cycling and propose an ecologically sound strategy to improve forest restoration success.

Spontaneous intramural small-bowel hematoma: a cause of acute abdomen in anticoagulated patients.

Spontaneous intramural small-bowel hematoma (SISBH) is an uncommon cause of acute abdominal pain in anticoagulated patients.

Brunneroma: an infrequent duodenal neoplasm.

An 83-year-old male presented to the Emergency Department with long lasting epigastric discomfort, weight loss and diarrhea. Physical exam and basic laboratory tests showed no remarkable findings. Upper endoscopy revealed a sessile lesion (Paris 0-IIa) in the anterior wall of the duodenal bulb, with smooth surface and slightly ulcerated at the top.

Neuromodulation of the prefrontal cortex facilitates diet-induced weight loss in midlife women: a randomized, proof-of-concept clinical trial.

BACKGROUND: High body mass index (BMI) is associated with neurocognitive impairments that contribute to overeating and interfere with weight loss efforts. Overweight and obesity at midlife can accelerate neurodegenerative changes and increase the risk of late-life dementia. Noninvasive neuromodulation represents a novel, affordable and scalable approach to improve neurocognitive function in this context. The purpose of this proof-of-concept study was to examine whether transcranial direct current stimulation (tDCS) aimed at enhancing prefrontal cortex activity could enhance weight loss, in combination with a hypocaloric diet, and study underlying mechanisms. METHODS: Overall, 38 women with BMI 25-35 kg/m2 underwent a 4 week randomized, double-blinded, sham-controlled, and parallel-design intervention, during which they received eight sessions of tDCS (n = 18 sham, n = 20 active) in combination with a diet (caloric goal of 20 kcal/kg/day). We evaluated longitudinal changes in body weight, appetite and food craving. In addition, we examined the contribution of cognitive-executive processes via food-modified computerized tasks. RESULTS: We found that the active group had more reduction in body weight than the sham group throughout the study (p = 0.020) and significant weekly weight loss. At 4 weeks, the active group lost 2.32% of initial body weight (sham: 1.29%). Components of subjective appetite and food craving showed a trend toward more reduction in the active group. These changes were paralleled by significant improvements in task performance in the active group, particularly in a dual task that required inhibitory control and working memory (p = 0.007-0.031). Improvement in inhibitory control performance predicted reduction in lack of control overeating, explaining 43.5% of its variance at the end of the study (p = 0.003). No significant adverse effects were observed. CONCLUSIONS: Our results provide proof-of-concept validation of prefrontal-targeted tDCS, combined with a diet, in midlife women with excess body weight, paving the way for larger studies evaluating clinical efficacy and long-term effects of this intervention.

Fibromyalgia and non-celiac gluten sensitivity: a description with remission of fibromyalgia.

Fibromyalgia (FM) syndrome is a disabling clinical condition of unknown cause, and only symptomatic treatment with limited benefit is available. Gluten sensitivity that does not fulfill the diagnostic criteria for celiac disease (CD) is increasingly recognized as a frequent and treatable condition with a wide spectrum of manifestations that overlap with the manifestations of FM, including chronic musculoskeletal pain, asthenia, and irritable bowel syndrome. The aim of this report was to describe 20 selected patients with FM without CD who improved when placed on a gluten-free diet. An anti-transglutaminase assay, duodenal biopsy, and HLA typing were performed in all cases. CD was ruled out by negative anti-transglutaminase assay results and absence of villous atrophy in the duodenal biopsy. All patients had intraepithelial lymphocytosis without villous atrophy. Clinical response was defined as achieving at least one of the following scenarios: remission of FM pain criteria, return to work, return to normal life, or the discontinuation of opioids. The mean follow-up period was 16 months (range 5-31). This observation supports the hypothesis that non-celiac gluten sensitivity may be an underlying cause of FM syndrome.

Conversion from Roux-En-Y Gastric Bypass to Single Anastomosis Duodenoileal Bypass (SADI-S) for Weight Regain.

BACKGROUND: Revisional bariatric surgery presents a challenge for bariatric surgeons. This procedure can be considered for patients with inadequate weight loss or weight regain after an initial satisfactory response following bariatric surgery. However, the surgical management of weight regain following RYGB remains controversial. We present a case of successful weight gain management after a single anastomosis duodenoileal bypass with sleeve gastrectomy (SADIS) as a revisional procedure for patients with weight regain after RYGB. METHODS: A 23-year-old female with a body mass index (BMI) of 52 kg/m2 and no comorbidities underwent RYGB. Postoperatively, she reached an excess weight loss of 75% of her initial body weight, with a BMI of 32 kg/m2. Eight years after her RYGB, she started regaining weight, reaching a BMI of 47 kg/m2. The surgical team decided to perform a revisional surgery, a conversion of RYGB to SADIS. RESULTS: There were no intraoperative complications. An upper gastrointestinal series was obtained on the third postoperative day which resulted normal and oral feedings were resumed. The patient was then discharged on fifth postoperative day. There were no complications within the first 30 postoperative days. CONCLUSIONS: We attach a video that illustrates the management and technique used to deal with the weight regain after primary bariatric surgery RYGB. We consider that in patients with super morbid obesity refractory to RYGB, conversion to SADIS is an excellent alternative due to its safety and feasibility.

Factors associated with Marburg hemorrhagic fever: analysis of patient data from Uige, Angola.

BACKGROUND: Reliable on-site polymerase chain reaction (PCR) testing for Marburg hemorrhagic fever (MHF) is not always available. Therefore, clinicians triage patients on the basis of presenting symptoms and contact history. Using patient data collected in Uige, Angola, in 2005, we assessed the sensitivity and specificity of these factors to evaluate the validity of World Health Organization (WHO)-recommended case definitions for MHF. METHODS: Multivariable logistic regression was used to identify independent predictors of PCR confirmation of MHF. A data-derived algorithm was developed to obtain new MHF case definitions with improved sensitivity and specificity. RESULTS: A MHF case definition comprising (1) an epidemiological link or (2) the combination of myalgia or arthralgia and any hemorrhage could potentially serve as an alternative to current case definitions. Our data-derived case definitions maintained the sensitivity and improved the specificity of current WHO-recommended case definitions. CONCLUSIONS: Continued efforts to improve clinical documentation during filovirus outbreaks would aid in the refinement of case definitions and facilitate outbreak control.

Proposal of a holistic model to support local-level evidence-based practice.

In response to a central drive for evidence-based practice, there have been many research support schemes, setups, and other practices concentrating on facilitating access to external research, such as the Centre for Evidence Based Healthcare Aotearoa, the Cochrane Collaboration, and the York Centre for Reviews and Dissemination. Very little attention has been paid to supporting internal research in terms of local evidence and internal research capabilities. The whole evidence-based practice movement has alienated internal decision makers and, thus, very little progress has been made in the context of evidence informing local policy formation. Health and social policies are made centrally based on dubious claims and often evidence is sought after implementation. For example, on record, most health care practitioners appear to agree with the causal link between depression and mental illness (sometimes qualified with other social factors) with suicide; off the record, even some psychiatrists doubt that such a link is applicable to the population as a whole. Therefore, be it through misplaced loyalty or a lack of support for internal researchers/decision makers, local evidence informing local decision making may have been ignored in favour of external evidence. In this paper, we present a practical holistic model to support local evidence-based decision making. This approach is more relevant in light of a new approach to primary health care of "local knowledge" complementing external evidence. One possible outcome would be to network with other regional programmes around the world to share information and identify "best" practices, such as the "Stop Youth Suicide Campaign" (www.stopyouthsuicide.com).

Creating Health Literate Consumer Resources: Insights from a Professional Development Program.

The Rauemi Atawhai (RA) Program, delivered at Counties Manukau Health by Health Literacy New Zealand (Limited), is a professional development program that aims to develop the capability in health care professionals to recognize and develop health literate, culturally competent health education resources and systems. Local evaluation of this program explored participant learning and barriers to becoming a health literate organization. We found that program participants consolidated their understanding or built a more comprehensive understanding of health literacy. Further, they gained new skills to assist them in developing future consumer resources. However, within the evaluation period, the RA Program had limited influence on the design and refinement of systems for developing, reviewing, disseminating, and evaluating consumer resources for their service, as well as approaches for engaging patients and family in design and review. Significant organizational action is needed to support these changes. Opportunities for leaders and managers to participate in capability building and discussions to create conditions (e.g., resource and authorization) for change in the environments in which staff work are needed.

Saving 20 000 Days and Beyond: a realist evaluation of two quality improvement campaigns to manage hospital demand in a New Zealand District Health Board.

Background: The current paper reports on a realist evaluation of two consecutive quality improvement campaigns based on the Institute for Healthcare Improvement's Breakthrough Series. The campaigns were implemented by a District Health Board to manage hospital demand in South Auckland, New Zealand. A realist evaluation design was adopted to investigate what worked in the two campaigns and under what conditions. Methods: A mixed-methods approach was used, involving three phases of data collection. During the first phase, a review of campaign materials and relevant literature, as well as key informant interviews were undertaken to generate an initial logic model of how the campaign was expected to achieve its objective. In phase II, the model was tested against the experiences of participants in the first campaign via a questionnaire to all campaign participants, interviews with campaign sponsors and collaborative team leaders and a review of collaborative team dashboards. In phase III, the refined model was tested further against the experiences of participants in the second campaign through interviews with collaborative team leaders, case studies of four collaborative teams and a review of the overall system-level dashboard. Results: The evaluation identified four key mechanisms through which the campaigns' outcomes were achieved. These were characterised as 'an organisational preparedness to change', 'enlisting the early adopters', 'strong collaborative teams' and 'learning from measurement'. Contextual factors that both enabled and constrained the operation of these mechanisms were also identified. Conclusions: By focusing on the explication of a theory of how the campaigns achieved their outcomes and under what circumstances, the realist evaluation reported in this paper provides some instructive lessons for future evaluations of quality improvement initiatives.

Wet and dry tropical forests show opposite successional pathways in wood density but converge over time.

Tropical forests are converted at an alarming rate for agricultural use and pastureland, but also regrow naturally through secondary succession. For successful forest restoration, it is essential to understand the mechanisms of secondary succession. These mechanisms may vary across forest types, but analyses across broad spatial scales are lacking. Here, we analyse forest recovery using 1,403 plots that differ in age since agricultural abandonment from 50 sites across the Neotropics. We analyse changes in community composition using species-specific stem wood density (WD), which is a key trait for plant growth, survival and forest carbon storage. In wet forest, succession proceeds from low towards high community WD (acquisitive towards conservative trait values), in line with standard successional theory. However, in dry forest, succession proceeds from high towards low community WD (conservative towards acquisitive trait values), probably because high WD reflects drought tolerance in harsh early successional environments. Dry season intensity drives WD recovery by influencing the start and trajectory of succession, resulting in convergence of the community WD over time as vegetation cover builds up. These ecological insights can be used to improve species selection for reforestation. Reforestation species selected to establish a first protective canopy layer should, among other criteria, ideally have a similar WD to the early successional communities that dominate under the prevailing macroclimatic conditions.

Field evaluation of a rapid immunochromatographic assay for detection of Trypanosoma cruzi infection by use of whole blood.

Laboratory and clinical diagnostic classification of seropositive individuals, followed by treatment and supportive therapy, is an established component of Chagas' disease control in areas where this disease is endemic. However, most Chagas' disease patients live in remote areas where neither equipped laboratories nor skilled human resources are widely available. Employing a rapid diagnostic test (RDT), when using whole blood samples, is the best option for Chagas' disease control. A high sensitivity and specificity for the Chagas Stat-Pak RDT (Chembio Diagnostic Systems, Inc., Medford, NY) has been reported for assays using serum and plasma, but its validity for the detection of antibodies to Trypanosoma cruzi infection in whole blood is unknown. This cross-sectional study measured the sensitivity and specificity of the Chagas Stat-Pak with whole blood, using conventional serological assays for comparison. The interobserver reliability in the interpretation of the Chagas Stat-Pak results and "ease-of-use" criterion needed to perform the Chagas Stat-Pak and conventional assays were also measured. The Chagas Stat-Pak yielded a high specificity (99.0%, 95% confidence interval [CI] = 98.4 to 99.4%) but a relatively low sensitivity (93.4%, 95% CI = 87.4 to 97.1%). The interobserver reliability was excellent (kappa [n = 1,913] = 0.999, P < 0.0001), and the quantified ease-of-use criterion suggested that the RDT is simple to perform. Despite the attributes of the Chagas Stat-Pak, it is not an ideal diagnostic test for the population investigated in the present study due to its relatively low sensitivity and high cost. The RDT manufacturer is called upon to improve the test if the international community hopes to make progress in controlling Chagas infections in areas where this disease is endemic.

What initiatives do healthcare leaders agree are needed for healthcare system improvement? Results of a modified-Delphi study.

PURPOSE: The purpose of this paper is to identify five quality improvement initiatives for healthcare system leaders, produced by such leaders themselves, and to provide some guidance on how these could be implemented. DESIGN/METHODOLOGY/APPROACH: A multi-stage modified-Delphi process was used, blending the Delphi approach of iterative information collection, analysis and feedback, with the option for participants to revise their judgments. FINDINGS: The process reached consensus on five initiatives: change information privacy laws; overhaul professional training and work in the workplace; use co-design methods; contract for value and outcomes across health and social care; and use data from across the public and private sectors to improve equity for vulnerable populations and the sickest people. RESEARCH LIMITATIONS/IMPLICATIONS: Information could not be gathered from all participants at each stage of the modified-Delphi process, and the participants did not include patients and families, potentially limiting the scope and nature of input. PRACTICAL IMPLICATIONS: The practical implications are a set of findings based on what leaders would bring to a decision-making table in an ideal world if given broad scope and capacity to make policy and organisational changes to improve healthcare systems. ORIGINALITY/VALUE: This study adds to the literature a suite of recommendations for healthcare quality improvement, produced by a group of experienced healthcare system leaders from a range of contexts.

A literature review for large-scale health information system project planning, implementation and evaluation.

Information technology is perceived as a potential panacea for healthcare organisations to manage pressure to improve services in the face of increased demand. However, the implementation and evaluation of health information systems (HIS) is plagued with problems and implementation shortcomings and failures are rife. HIS implementation is complex and relies on organisational, structural, technological, and human factors to be successful. It also requires reflective, nuanced, multidimensional evaluation to provide ongoing feedback to ensure success. This article provides a comprehensive review of the literature about evaluating and implementing HIS, detailing the challenges and recommendations for both evaluators and healthcare organisations. The factors that inhibit or promote successful HIS implementation are identified and effective evaluation strategies are described with the goal of informing teams evaluating complex HIS.

Estimated reduction in expenditure on hospital-acquired pressure injuries after an intervention for early identification and treatment.

AIM: An intervention designed to reduce numbers of hospital-acquired pressure injuries was delivered in Counties Manukau Health hospitals. An audit of a sample of patients was carried out to estimate the cost savings that would have been acquired across the district health board (DHB) due to a reduction in pressure injuries. METHOD: The pressure injury intervention was delivered from 2011 to 2015. A monthly prospective audit of patients with stages 1, 2, 3 and 4 pressure injuries was carried out. This involved a random sample of five patients per ward in all hospitals in Counties Manukau DHB. RESULTS: It was found that the annual estimated cost of treating pressure injuries in hospital patients was NZ$12,290,484 less in 2015 than in 2011. CONCLUSION: Implementation of strategies for managing hospital-acquired pressure injuries can lead to potentially large financial savings for hospitals, as well as reducing the burden of managing this difficult condition for patients and staff.

TRPA1 polymorphisms in chronic and complete spinal cord injury patients with neuropathic pain: a pilot study.

STUDY DESIGN: Pilot study. OBJECTIVES: Single-nucleotide polymorphisms (SNPs) in TRPA1 gene are related to the etiology of chronic pain. The study is a pilot study with the primary objective of analyzing these SNPs in Spanish patients with chronic and complete spinal cord injury (SCI) and neuropathic pain (NPP). SETTING: Asepeyo Hospital Department of Chronic and Complete SCI. METHODS: Twelve patients with chronic and complete SCI and NPP, and 12 patients with chronic and complete SCI with no pain were reviewed. International Spinal Cord Injury Pain Classification (LANSS) and visual analog score (VAS) were chosen to classify pain syndrome. SNPs were identified by melting analysis after DNA amplification with real-time fluorescence PCR. RESULTS: There were differences in rs11988795 variant: GG homozygous (p = 0.01) and G allele (p = 0.001) were more frequent in SCI patients with no pain. There were differences in rs13255063 variant: TT homozygous were prevalent (p = 0.03) in patients with NPP. CONCLUSIONS: Until now this is the first study to show a description of TRPA1 SNPs in Spanish patients with chronic and complete SCI and NPP. These results suggest that GG genotype in rs11988795 variant and G allele could be protective factors against NPP. TT genotype in rs13255063 variant could be a risk factor for NPP. Neuropathic pain after spinal cord injuries may have genetic contributions.

My Home is My Marae: Kaupapa Maori evaluation of an approach to injury prevention.

OBJECTIVE: The objective of this study was to evaluate the New Zealand Accident Compensation Corporation's (ACC) 'My Home is My Marae' approach to injury prevention for whanau (families). SETTING: Over an 18 month period from November 2013 to June 2014, 14 'My Home is My Marae' trials were conducted across the South Auckland and Far North regions of New Zealand. ACC engaged with local Maori providers of healthcare, education and social services to deliver the home safety intervention. PARTICIPANTS: Participants of this evaluation were a purposive sample of 14 staff from six provider organisations in South Auckland and the Far North regions of New Zealand. METHODS: Kaupapa Maori theory-based evaluation and appreciative inquiry methodologies underpinned the evaluation. Interview participants led discussions about strengths and weaknesses of the approach, and partnerships with ACC and other organisations. The evaluation was also supported by pre-existing information available in project documentation, and quantitative data collected by Maori providers. RESULTS: Five key critical success factors of 'My Home is My Marae' were found from interviews: mana tangata (reputation, respect and credibility); manakitanga (showing care for people); kanohi-ki-te-kanohi (face-to-face approach); capacity building for kaimahi, whanau and providers and 'low or no cost' solutions to hazards in the home. Data collected for the Far North area showed that 76% of the hazards identified could be resolved through 'low or no cost' solutions. Unfortunately, similar data were not available for South Auckland. CONCLUSIONS: Injury prevention or health promotion approaches that seek to engage with whanau and/or Maori communities would benefit from applying critical success factors of 'My Home is My Marae'.

Evaluation of general practice house officer attachments in Counties Manukau: insights and benefits.

BACKGROUND The Medical Council of New Zealand requires graduating doctors to have community attachments within their first two years of practice by 2020. Counties Manukau Health has developed a programme where house officers (HOs) are attached to a general practice for three months. AIM This study aimed to establish the value of four HO general practice attachments in Counties Manukau and describe how HOs are being used in these practices. METHODS A mixed-methods design was used to evaluate three attachment runs. Two practices provided the number of patients seen by HOs. Fifty-eight patients were surveyed to assess patient perceptions of the HOs. Six HOs, four supervising general practitioners, two PHO senior staff and one practice manager participated in semi-structured interviews. Focus groups were held with nurses, doctors and administrative staff at all four practices. FINDINGS HOs saw 300-600 patients in one practice and 800-1000 in the other during their attachment. Practices developed their own approach to mentoring and teaching HOs. Most patients reported positive perceptions of the HOs. Themes from interviews and focus groups were consistent among participants and included: improved HO confidence, clinical skills and understanding of general practice; extra capacity and improved quality of care and staff satisfaction among practices. CONCLUSION HOs and practices viewed HO attachments in general practice positively. HOs developed clinical skills and understanding of primary health care. Practice teams enjoyed the energy and enthusiasm of the HOs, while providing clinical support to ensure quality patient care.
