Abstract
We explored issues around the integration of survivors in communities and the implications for the Ebola Virus Disease (EVD) response in the Democratic Republic of Congo (DRC). We conducted a survey with 800 randomly selected respondents using a structured questionnaire. Respondents were persons aged 18 years and above. Focus group discussions (FGDs) and in-depth interviews (IDIs) were employed to obtain contextual data on the issues. Community leaders, health workers, and response pillar leads engaged in IDIs, while community members were involved in FGDs. The results revealed that the survivors suffered stigmatization and, upon return to the communities, were avoided by the community members due to fear of contamination. Some thought that the survivors should be supported in adjusting to the community, while some recommended engaging the survivors in EVD response activities.

Heart failure with recovered ejection fraction: Current understanding and future prospects. Am J Med Sci 2023; 365:1-8. [PMID: 36084706 DOI: 10.1016/j.amjms.2022.07.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Revised: 01/18/2022] [Accepted: 07/12/2022] [Indexed: 01/04/2023]
Abstract
Heart failure with reduced ejection fraction (HFrEF) is a prevalent kind of heart failure in which a significant amount of the ejection fraction can be repaired, and left ventricular remodeling and dysfunction can be reversed or even restored completely. However, a considerable number of patients still present clinical signs and biochemical features of incomplete recovery from the pathophysiology of heart failure and are at risk for adverse outcomes such as re-deterioration of systolic function and recurrence of HFrEF. Furthermore, it is revealed from a microscopic perspective that even if partial or complete reverse remodeling occurs, the morphological changes of cardiomyocytes, extracellular matrix deposition, and abnormal transcription and expression of pathological genes still exist. Patients with "recovered ejection fraction" have milder clinical symptoms and better outcomes than those with continued reduction of ejection fraction. Based on the unique characteristics of this subgroup and the existence of many unknowns, the academic community defines it as a new category-heart failure with recovered ejection fraction (HFrecEF). Because there is a shortage of natural history data for this population as well as high-quality clinical and basic research data, it is difficult to accurately evaluate clinical risk and manage this population. This review will present the current understanding of HFrecEF from the limited literature.

Understanding relations between intolerance of uncertainty and body checking and body avoiding in anorexia nervosa. J Eat Disord 2022; 10:122. [PMID: 35982486 PMCID: PMC9389820 DOI: 10.1186/s40337-022-00647-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Accepted: 08/10/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND A key feature of anorexia nervosa is body image disturbances and is often expressed by dysfunctional body-related behaviours such as body checking and body avoiding. These behaviours are thought to contribute to both the maintenance and relapse of AN, yet empirical evidence is scarce. One variable that may contribute to the need for engaging in these behaviours is intolerance of uncertainty. This study aims to investigate body checking and body avoiding and its relations with intolerance of uncertainty in women with anorexia nervosa (AN-ill; 70), women recovered from AN (AN-rec; 85) and control group (127). METHODS Three questionnaires were completed, measuring eating pathology, intolerance of uncertainty and body checking and body avoiding. One-way ANOVAS were used to test group differences. Moderation analyses were used to investigate associations between variables. RESULTS Levels of intolerance of uncertainty, body checking and body avoiding were highest in AN-ill followed by AN-rec and, lastly, the control group, confirming group differences. Intolerance of uncertainty was associated with body checking in the AN-rec group and the control group but not in the AN-ill group. The association between intolerance of uncertainty and body avoiding was reported in the AN-rec group and only marginally in the control group. CONCLUSION Levels of intolerance of uncertainty, body checking and body avoiding were highest in AN-ill, however still elevated in AN-rec, confirming the presence of body image disturbances, even after recovery. The unique associations between intolerance of uncertainty and body checking and body avoiding within the studied groups may represent different stages of the illness. In the AN-rec group, the relation between intolerance of uncertainty, body checking and body avoiding may be driven by trait anxiety. For AN-ill group, body checking and body avoiding may eventually have grown into habitual patterns, rather than a strategy to ameliorate anxiety and uncertainty. Women with anorexia nervosa often experience disturbances in their body image and are expressed in body-related behaviours such as body checking and body avoiding. These behaviours are thought to contribute to both the maintenance and relapse of anorexia nervosa. Intolerance of uncertainty is defined as the incapacity to tolerate uncertainty and may contribute to the need for engaging in these behaviours. This study aims to investigate body checking and body avoiding and its relations with intolerance of uncertainty in women with anorexia nervosa (AN-ill; 70), women recovered from AN (AN-rec; 85) and control group (127). Three questionnaires were completed, measuring eating pathology, intolerance of uncertainty and body checking and body avoiding. Levels of intolerance of uncertainty, body checking and body avoiding were highest in AN-ill and still elevated in AN-rec, even after recovery. The associations between intolerance of uncertainty and body checking and body avoiding within the studied groups may represent different stages of the illness. In the AN-rec group, the relation between intolerance of uncertainty, body checking and body avoiding may be driven by trait anxiety. For AN-ill group, body checking and body avoiding may have grown into habitual patterns, rather than a strategy to ameliorate anxiety and uncertainty.

The course, trajectories and predictors of depression 23 years after the 1988 Spitak earthquake in Armenia: A prospective cohort study. Psychiatry Res 2022; 313:114640. [PMID: 35598565 DOI: 10.1016/j.psychres.2022.114640] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 05/04/2022] [Accepted: 05/14/2022] [Indexed: 11/19/2022]
Abstract
There is a scarcity of long-term studies of depression after natural disasters. This prospective epidemiologic study evaluated the course of depression and factors associated with it among survivors 23-years post-earthquake. A geographically stratified subsample of 725 adults exposed to the Spitak earthquake was assessed for depression using DSM-III-R criteria in 1991 and 2012. Additionally, an adapted CES-D-16 scale was used to assess depressive symptoms in 2012. A fitted multi-nominal logistic regression model identified predictors of different trajectories of depression. For the whole group, the rate of clinical depression dropped from 51.5% in 1991 to 31.7% in 2012. Earthquake intensity and experiencing strong fear at baseline were strongly associated with chronic (depressed at both assessments, 18.1%) and recovered (depressed only in 1991, 33.5%) depression trajectories compared with the healthy group, with odds ratios (OR) over 4.0 and 3.0, respectively. Predictors distinguishing chronic depression included earthquake-related nuclear-family deaths (OR=3.79), chronic illnesses at baseline (OR=1.24), and social support (OR=0.91). Predictors of the late-onset trajectory (depressed only in 2012, 13.5% of the cohort) included post-earthquake trauma (OR=1.42), socioeconomic status (OR=0.45), and social support (OR=0.86). The factors associated with the different trajectories of depression provide guidance for planning more effective mental health interventions after disasters.

Abstract
The need to feel in control is central to anorexia nervosa (AN). The sense of control in AN has only been studied through self-report. This study investigated whether implicit sense of control (sense of agency; SoA) differs across AN patients, recovered AN (RAN) patients and healthy controls (HC). Furthermore, we assessed whether state anxiety is influenced by negative emotional states. SoA was measured with the intentional binding task (IB) and state-anxiety levels through a questionnaire. We did not find any evidence of differences in SoA between groups. Furthermore, state anxiety was not a significant predictor of SoA. Further research into SoA in AN should focus on other features of the SoA that are not targeted by the IB task.

Abstract
AIMS Improvement in ejection fraction (EF) was observed in a subset of patients with heart failure (HF) and reduced ejection fraction (HFrEF). We analyzed and compared these patients with other HF phenotypes. METHODS Based on left ventricular ejection fraction(LVEF) at baseline and follow-up, the 561 HF patients were divided into 4 groups: HF preserved EF (HFpEF, LVEF ≥ 50% on both occasions, n = 258), HF mid-range EF (HFmrEF, fluctuating between LVEF 40 and 49% on both occasions, n = 61), HFrEF (LVEF < 40% on both occasions, n = 141), and HF improved EF (HFimpEF, defined as LVEF < 40% at baseline and LVEF ≥ 40% at follow-up with ≥10% absolute improvement, n = 101). The composite of HF readmission and all-cause mortality was considered the primary endpoint, and the secondary endpoint was all-cause mortality. RESULTS The characteristics of HFimpEF differed from other HF phenotypes. β-blockers and aldosterone receptor antagonists were associated with improved LVEF. Kaplan-Meier curves showed the lowest incidence of the composite endpoint (p < 0.001) and all-cause mortality (p < 0.001) in HFimpEF. The risk of cardiovascular death was lowest in HFimpEF after controlling for competing events (p < 0.001), as were competing events (p < 0.001). Valvular heart disease (VHD) (HR 8.555, 95 CI% 2.126-34.420, p = 0.003) increased the risk of all-cause death, and anemia increased the risk of all-cause death (HR 5.533, 95 CI% 1.592-19.530, p = 0.007) and cardiovascular death in HFimpEF patients (HR 5.840, 95 CI% 1.088-31.356, p = 0.040). CONCLUSIONS HFimpEF is an independent HF phenotype with a prognosis similar to HFmrEF and superior to HFpEF and HFrEF. When HFimpEF patients had VHD and anemia, the endpoint event rate was increased.

Abstract
Heart failure with recovered ejection fraction (HFrecEF) involves those who have previously had reduced cardiac function that has subsequently improved. However, there is not a single definition of this phenomenon and recovery of cardiac function in terms of left ventricular ejection fraction (LVEF) itself does not necessarily correlate with remission from the detrimental physiology of heart failure (HF) and its consequences. There is also the question of the utility of defibrillators in these patients, and whether they should be replaced at the time of battery depletion. To address this, several studies have shown specific predictors of ensuing LVEF recovery, including patient demographics, co‐morbidities, and medication use, as well as predictors of ventricular arrhythmias (VA) following LVEF recovery. Recent studies have also shown novel imaging parameters that may aid in predicting which patients would have a higher risk of these arrhythmias. Additional data describe a small, yet appreciable risk of VA, in addition to appropriate shocks as well. In this review, we describe predictors of LVEF recovery, carefully analyse and characterize the continued risk for VA and appropriate shocks following LVEF recovery, and explore additional novel modalities that may aid in decision‐making.

Cardiac involvement in patients recovered from COVID-19 identified using left ventricular longitudinal strain. J Echocardiogr 2021; 20:51-56. [PMID: 34648149 PMCID: PMC8514606 DOI: 10.1007/s12574-021-00555-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 09/28/2021] [Accepted: 10/06/2021] [Indexed: 02/07/2023]
Abstract
Introduction Coronavirus disease-19 (COVID-19) has been associated with subclinical myocardial dysfunction during its acute phase and a recurring pattern of reduced basal left ventricular longitudinal strain on speckle-tracking echocardiography (STE) in hospitalized patients. But a question still remains unanswered: speckle-tracking echocardiography might also be suitable to detect residual myocardial involvement after acute stage of COVID-19? Methods and results We studied 100 patients recovered from COVID-19 with STE to evaluate global (GLS) and segmentar longitudinal strain (LS) and compared with a control group of 100 healthy individuals. STE was performed at a median of 130.35 ± 76.06 days after COVID-19 diagnostic. Demographic and echocardiographic parameters are similar in both groups. Left ventricular ejection faction (LVEF) and GLS were normal in COVID-19 patients (66.20 ± 1.98% and − 19.51 ± 2.87%, respectively). A reduction in mean LS for the basal segments was found in COVID-19 (16.48 ± 5.41%) when compared to control group (19.09 ± 4.31%) (p < 0.001). Conclusion The present study suggests that COVID-19-induced cardiac involvement could persist after recovery of the disease and may be detected by deformation abnormalities using STE. COVID-19-induced myocardial involvement often shows specific LV deformation patterns due to pronounced edema and/or myocardial damage in basal LV segments.

Abstract
Fibrotic lung changes are well-known complications of SARS, MERS, and ARDS from other causes and are anticipated in recovered COVID patients. However, there is limited data so far showing a temporal relationship between lung changes on imaging in the acute phase and follow-up imaging after recovery from the infection. We present 12 patients who demonstrate the development of interstitial lung changes and pulmonary fibrosis in the same distribution and pattern as the acute phase findings, up to 6 months after the acute infection, demonstrating a direct relationship between these changes and COVID-19 pneumonia.

Abstract
As the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection spreads globally, physicians and physician-scientists are confronted with an enlarging body of literature about the nature of this pandemic. Understanding the current epidemiological models for disease spread, mortality, and recovery is more important than ever before. One of the most relevant mathematical models relating to the spread of a pandemic is the susceptible-infectious-removed (SIR) model. Other models worth exploring are the susceptible-exposed-infectious-removed (SEIR) and the susceptible-unquarantined-quarantined-confirmed (SUQC) model.

Abstract
Objective: Despite the fact that a practical definition of addiction recovery is necessary to conduct an appropriate intervention and research, this concept is still vague and there is no consensus over its meaning and how to measure it. Thus, this study aimed to define and clarify this concept based on the available literature. Method : The theoretical part of Schwartz_Barcott and Kim's Hybrid Model of concept analysis was used to analyze the concept of "Addiction Recovery." To find the relevant literature, an electronic search on valid databases was conducted using keywords related to the concept of addiction recovery. Medlib, IranMedex, Magiran, SID, Irandoc, Google Scholar, PubMed, Web of Science, Medline, Scopus, Pro Quest, CINAHL, Science Direct, Ovid, and Wiley databases were searched up to December 2018 without a time limitation using the following keywords: "Substance use disorders", "Drug use", "Recovery", "Opioids", "Addiction treatment", "Dependency", "Rehabilitation", Remission", "Concept analysis", "Restore", "Definition", "Meaning", and "Conceptualization". The Conventional content analysis was used on selected research articles. Results: From a total of 9520 articles, 39 were reviewed and analyzed. Five attributes were selected, including the process of change, being holistic, being client-centric, learning healthy coping, and being multistage. Antecedents are organized into 2 interacting categories: personal and social resources. Personal resources refer to the person, his/her addiction, and the treatment characteristics, while social resources refer to the family, the community, and the context resources. Addiction recovery leads to sustained abstinence, improved physical and psychological health, improved quality of life and satisfaction, meaningful living, and citizenship. Conclusion: These findings may form a basis for the theories, scales, and criteria for the assessment of addiction recovery and will be useful in clinical practices and research. Also, these findings could help health care professionals to understand the concept of addiction recovery, which is important in improving the recovering person in all aspects of rehabilitation. We will report the implementation and analytical phase of this research project, namely, "the addiction recovery concept analysis" in Iran.

Abstract
BACKGROUND The aim of this study was to review the existing literature and evaluate whether deficits in set-shifting, central coherence and decision-making persist in individuals recovered from anorexia nervosa (AN-REC). METHOD A systematic review approach was used. Literature was identified via searches in PubMed, PsychInfo and Embase database. The main search resulted in 158 articles. After exclusion of 135 articles, 23 articles were included in the review. RESULTS The majority of studies on set-shifting showed that set-shifting difficulties persist after recovery. Central coherence might also be trait related, however findings are inconsistent. Few studies have investigated decision-making in AN-REC, however those studies that do exist suggest that decision-making is not impaired in AN-REC. CONCLUSIONS Novel treatment strategies based on neuroscience research are emerging, focusing on targeting the underlying mechanisms of the illness, including neuropsychological functioning. Whether these functions are trait or state related could have implications for how they are targeted in treatment.

Abstract
AIMS Significant recovery of left ventricular ejection fraction (LVEF) occurs in a proportion of patients with heart failure (HF) and reduced ejection fraction (HFrEF). We analysed outcomes, including mortality [all-cause, cardiovascular (CV), HF-related, and sudden death], and HF-related hospitalizations in this HF-recovered group. The primary endpoint was a composite of CV death or HF hospitalization. METHODS AND RESULTS LVEF was assessed at baseline and at 1 year in 1057 consecutive HF patients. Patients were classified into three groups: (i) HF-recovered: LVEF <45% at baseline and ≥45% at 1 year (n = 233); (ii) HF with preserved EF (HFpEF): LVEF ≥45% throughout follow-up (n = 117); and (iii) HFrEF: LVEF <45% throughout follow-up (n = 707). Mean follow-up was 5.6 ± 3.1 years. HF-recovered patients differed from HFrEF and HFpEF groups in demographic and clinical characteristics. The mean LVEF increase was 21.1 ± 10 points in HF-recovered patients. Using the HF-recovered group as a reference, the risks for the primary composite endpoint (n = 376), with non-CV death as competing risk, for HFpEF and HFrEF groups were: hazard ratio (HR) 2.33 [95% confidence interval (CI) 1.60-3.39], P < 0.001 and HR 1.99 (95% CI 1.50-2.65), P < 0.001, respectively. All-cause (n = 429), CV (n = 245), HF-related (n = 127), and sudden death (n = 60) were significantly lower in HF-recovered subjects relative to HFrEF (all P < 0.01). HF-recovered patients also experienced less recurrent HF hospitalizations (P < 0.001). CONCLUSION One in four treated patients with HFrEF showed recovery of systolic function. HF-recovered patients had significantly improved mortality and morbidity relative to HFpEF and HFrEF subjects. Further research is needed to identify optimal medications and device indications for HF-recovered patients.

Abstract
PURPOSE A subgroup of individuals with anorexia nervosa (AN) displays social difficulties; however, it is not clear if individuals with comorbid autism spectrum disorders account for these difficulties. METHODS We compared social function using the Autism Diagnostic Observation Schedule in 43 young females with first-episode AN who did not have comorbid autism spectrum disorder, 28 individuals recovered from adolescent-onset AN, and 41 healthy comparison individuals (age range 14-22 years). We measured adaptive behavior with the Vineland-II parent questionnaire, and aspects of social cognition with psychological tests, such as the Reading-the-Mind-in-the-Eyes test, Profile of Nonverbal Sensitivity short version, The Awareness of Social Inference Test, Animated Triangles, and the CANTAB Affective Go/No-go task. RESULTS Participants with first-episode AN and those recovered from AN displayed difficulties in social function, which were not associated with body mass index or other state factors of the disorder in those with first-episode AN. Mood problems and anxiety were not associated with these difficulties. Parents rated participants with first-episode AN lower than recovered and control participants on the Socialization Domain of Vineland-II. Finally, only participants recovered from AN demonstrated deficits in specific domains of social cognition: perceiving nonverbal bodily gesture and vocal prosody. CONCLUSIONS Young females with first-episode AN and those recovered from AN displayed impairments in social function, which may represent more stable traits of the disorder. Only participants recovered from AN demonstrated deficits in social cognition.

Abstract
BACKGROUND Young individuals with anorexia nervosa (AN) or recovered from AN display impairments of social function. To date, however, it is not clear whether they differ from controls with respect to neurocognitive performance and whether those functions contribute to the compromised social function observed in individuals with AN. METHODS We included 43 young females with first-episode AN, 28 individuals recovered from adolescent-onset AN, and 41 control individuals (14-22 yr), all without comorbid autism spectrum disorder. We compared the performance of participants across groups in seven neurocognitive functions relevant to social functioning: set-shifting, local processing, processing speed, working memory, sustained attention, verbal memory, and verbal abstraction. Further, we tested the association between neurocognitive function and social function, measured by Autism Diagnostic Observation Schedule (ADOS), with an ordinal logistic regression model. RESULTS First, participants did not differ on any neurocognitive function across groups. Second, only the neurocognitive function "verbal memory" was significantly associated with social function. Higher performance in verbal memory was associated with lower odds of impaired social function. Diagnostic group remained a significant factor, but the absence of an interaction between group and neurocognitive performance indicated that the association between verbal memory and social function was independent of group membership. CONCLUSION Young individuals with AN and those recovered from AN did not differ from controls with respect to neurocognitive performance. Verbal memory was associated with social function in all groups.

Abstract
BACKGROUND The term "recovery" is widely used in the substance abuse literature and clinical settings, but data have not been available to empirically validate how recovery is defined by individuals who are themselves in recovery. The "What Is Recovery?" project developed a 39-item definition of recovery based on a large nationwide online survey of individuals in recovery. The objective of this paper is to report on the stability of those definitions one to two years later. METHODS To obtain a sample for studying recovery definitions that reflected the different pathways to recovery, the parent study involved intensive outreach. Follow-up interviews (n=1237) were conducted online and by telephone among respondents who consented to participate in follow-up studies. Descriptive analyses considered endorsement of individual recovery items at both surveys, and t-tests of summary scores studied significant change in the sample overall and among key subgroups. To assess item reliability, Cronbach's alpha was estimated. RESULTS Rates of endorsement of individual items at both interviews was above 90% for a majority of the recovery elements, and there was about as much transition into endorsement as out of endorsement. Statistically significant t-test scores were of modest magnitude, and reliability statistics were high (ranging from .782 to .899). CONCLUSIONS Longitudinal analyses found little evidence of meaningful change in recovery definitions at follow-up. Results thus suggest that the recovery definitions developed in the parent "What Is Recovery?" survey represent stable definitions of recovery that can be used to guide service provision in Recovery-Oriented Systems of Care.

Updating emotional content in recovered depressed individuals: Evaluating deficits in emotion processing following a depressive episode. J Behav Ther Exp Psychiatry 2015; 48:156-63. [PMID: 25889375 PMCID: PMC4524779 DOI: 10.1016/j.jbtep.2015.03.009] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2014] [Revised: 01/26/2015] [Accepted: 03/15/2015] [Indexed: 11/15/2022]
Abstract
BACKGROUND AND OBJECTIVES Previous research has demonstrated that depressed individuals have difficulty both disengaging from negative information and maintaining positive information in working memory (WM). The present study was conducted to examine whether the tendency for depressed individuals to maintain negative content in WM and to experience difficulties maintaining positive content in WM is due to negative mood (in)congruency effects during a depressive episode, or whether these tendencies are evident outside of a depressive episode. METHODS Individuals who had recovered from a depressive episode and never disordered controls performed emotion 0-back and 2-back tasks designed to assess biases in updating emotional content in working memory. RESULTS Similar to currently depressed individuals in previous studies, recovered depressed participants disengaged from happy stimuli more quickly and from sad stimuli more slowly than did their never-depressed counterparts. LIMITATIONS Despite the extension of a depression-specific finding to recovered depressed individuals, the present study does not test whether the identified emotion updating biases predict long-term relapse or recovery. CONCLUSION The obtained results suggest that a decreased ability to disengage from negative content and to maintain positive content in WM represents a trait-like cognitive style that impairs adaptive emotion regulation and may contribute to the recurrent nature of depression.

How do recovery definitions distinguish recovering individuals? Five typologies. Drug Alcohol Depend 2015; 148:109-17. [PMID: 25630961 PMCID: PMC4330112 DOI: 10.1016/j.drugalcdep.2014.12.036] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2014] [Revised: 12/16/2014] [Accepted: 12/22/2014] [Indexed: 11/29/2022]
Abstract
BACKGROUND Six percent of American adults say they are "in recovery" from an alcohol or drug problem yet only a scant emergent literature has begun to ask how they define "recovery" or explored whether there is heterogeneity among their definitions. METHODS Secondary analysis of the "What is Recovery?" online survey employed latent class analysis (LCA) to identify typologies of study participants based on their actual endorsement of 39 recovery elements and to compare the composition of these typologies in terms of distinguishing personal characteristics. RESULTS A five-class solution provided the best fit and conceptual representation for the recovery definitions. Classes were labeled 12-step traditionalist (n=4912); 12-step enthusiast (n=2014); secular (n=980); self-reliant (n=1040); and atypical (n=382) based on patterns of endorsement of the recovery elements. Abstinence, spiritual, and social interaction elements differentiated the classes most (as did age and recovery duration but to a lesser extent). Although levels and patterns of endorsement to the elements varied by class, a rank-ordering of the top 10 elements indicated that four elements were endorsed by all five classes: being honest with myself, handling negative feelings without using, being able to enjoy life, and process of growth and development. CONCLUSIONS The results of the LCA demonstrate the diversity of meanings, and varying degrees of identification with, specific elements of recovery. As others have found, multiple constituents are invested in how recovery is defined and this has ramifications for professional, personal, and cultural processes related to how strategies to promote recovery are implemented.

Global epidemic invasion thresholds in directed cattle subpopulation networks having source, sink, and transit nodes. J Theor Biol 2015; 367:203-221. [PMID: 25524151 DOI: 10.1016/j.jtbi.2014.12.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2013] [Revised: 11/04/2014] [Accepted: 12/08/2014] [Indexed: 11/23/2022]
Abstract
Through the characterization of a metapopulation cattle disease model on a directed network having source, transit, and sink nodes, we derive two global epidemic invasion thresholds. The first threshold defines the conditions necessary for an epidemic to successfully spread at the global scale. The second threshold defines the criteria that permit an epidemic to move out of the giant strongly connected component and to invade the populations of the sink nodes. As each sink node represents a final waypoint for cattle before slaughter, the existence of an epidemic among the sink nodes is a serious threat to food security. We find that the relationship between these two thresholds depends on the relative proportions of transit and sink nodes in the system and the distributions of the in-degrees of both node types. These analytic results are verified through numerical realizations of the metapopulation cattle model.
