As Ethiopia advances towards efficient resource utilization and UHC through strategic health purchasing, the institutionalization of HTA will play a critical role. This study aims to identify key stakeholders, analyze the political economy surrounding HTA and priority setting in Ethiopia, and assess existing skills and capacities for a robust and sustainable HTA system.
Methods
We employed a mixed-method approach, combining 16 key informant interviews, 24 document reviews, and a cross-sectional survey (n=65) to assess national HTA capacity. We employed the Walt and Gilson policy analysis triangle framework, alongside Campos and Reich’s framework, to evaluate the context, process, content, and actors influencing HTA institutionalization, and to explore the complex interplay of institutions, positions, power, and interests among various stakeholders.
Results
While there is a general commitment to implementing HTA across various government agencies and stakeholder groups, the institutionalization process faces several challenges, involving multiple agencies with overlapping mandates, raises bureaucratic challenges and potential conflicts, risking horizontal fragmentation as agencies compete for authority, budget, and influence. The involvement of other key stakeholders, such as professional associations, patients, and the public, is notably lacking. Challenges such as limited HTA expertise, high professional turnover, and gaps in specific HTA knowledge areas persist, with capacity-building efforts often failing to address organizational needs effectively.
Conclusions
The complexity of HTA institutionalization in Ethiopia underscores the necessity of managing intricate inter-agency dynamics, establishing a robust legal framework for an inclusive and transparent HTA process, building local capacity, and securing sustainable, domestically aligned funding.
This article introduces a Human-centred Engineering Design (HcED) practice, which values human aspects. This practice engages deeply into (1) human geometry and motion for specific tasks, (2) product and manufacturing complexities through rapid prototyping, and (3) the broader human task context. This cross-disciplinary method combines ergonomics, AM, sensor applications, and multiple design practices. The framework provides concrete tasks to drive innovative designs in engineering. The study, grounded in design research case studies, led to five new Paralympic Rowing world records.
In Fused Filament Fabrication, there is increasing interest in the potential of composite filaments for producing complex and load-bearing components. Carbon fibre-filled polyamide currently has highest available strength and stiffness, but promising variants are not in filament form. This paper investigates filament production of commercially available, high-filled PA-CF pellets by modifying a tabletop filament extruder. We show filament production is possible by improving cooling. The FFF printed specimens show an average UTS of 135.5 MPa, higher than most commercially available filaments.
OBJECTIVES/GOALS: The cytoskeletal protein α²II spectrin interacts with actin and ankyrin-2 in cardiomyocytes which is essential to orchestrate ion channels and membrane proteins in the cardiac dyad. Our goal is to understand molecular mechanism causing severe ventricular arrhythmias due to spectrin dysfunction and explore novel therapies to treat such conditions. METHODS/STUDY POPULATION: We previously published a case of a 36-year-old woman with an ankyrin-2 p.R990Q (ANK2) variant, presented with severe ventricular arrhythmias and sudden cardiac arrest, caused by a novel mutation in the ankyrin-B gene (c.2969G>A) that disrupts the interaction of ankyrin-B/βII spectrin. To model the condition, we will use human induced pluripotent stem cell (DF 19-9-7T, WiCell)-derived ventricular cardiomyocytes (iPSC-CMs) having ANK2 variant, engineered using CRISPR/Cas9 method (Synthego Corp.). We will validate the differentiation of iPSCs into ventricular lineage and characterize the ANK2 ventricular phenotype. Next, we will express light-gated cation channel Channelrhodopsin (ChR2) in the ANK2 iPSC-CMs and investigate the potential role of optogenetics in treating such severe arrhythmias. RESULTS/ANTICIPATED RESULTS: Immunostaining shows 87.339% of iPSC-CMs, treated with All-trans retinoic acid (RA) (1 uM) on days 7 and 12 [RA 7,12], and 23.84% of those, treated on days 3 and 5 [RA 3,5], expressed MLC-2V (p<0.001). Calcium reuptake (τ) is 0.5914 s in RA 7, 12 while 0.2247s in RA 3, 5 (p<0.001). APD90 and APD50 of RA 7, 12 are 2- and 5-fold higher than RA 3, 5, showing distinct ventricular and atrial phenotypes. Protein expression of βII-spectrin and ankyrin-2 and their co-localizations were reduced in the ANK2 phenotype compared to the healthy phenotype. We found prolongation of Ca2+ waves and τ with blue light on iPSC-CMs, expressing ChR2. We anticipate that such prolongation of calcium transients would prevent aberrant calcium spikes, rescue Ca2+/calpain-induced βII-spectrin loss and provide electrical stability. DISCUSSION/SIGNIFICANCE: Animal models cannot accurately recapitulate human cardiac electrophysiology. The proposed human iPSC-CM-based ANK2 model would provide better mechanistic insights of severe ventricular arrhythmias. Also, the proposed optogenetic cardioversion has the potential to provide safe, targeted and painless cardioversion to manage arrhythmias.
More knowledge about positive outcomes for people with first-episode psychosis (FEP) is needed. An FEP 10-year follow-up study investigated the rate of personal recovery, emotional wellbeing, and clinical recovery in the total sample and between psychotic bipolar spectrum disorders (BD) and schizophrenia spectrum disorders (SZ); and how these positive outcomes overlap.
Methods
FEP participants (n = 128) were re-assessed with structured clinical interviews at 10-year follow-up. Personal recovery was self-rated with the Questionnaire about the Process of Recovery-15-item scale (total score ⩾45). Emotional wellbeing was self-rated with the Life Satisfaction Scale (score ⩾5) and the Temporal Experience of Pleasure Scale (total score ⩾72). Clinical recovery was clinician-rated symptom-remission and adequate functioning (duration minimum 1 year).
Results
In FEP, rates of personal recovery (50.8%), life satisfaction (60.9%), and pleasure (57.5%) were higher than clinical recovery (33.6%). Despite lower rates of clinical recovery in SZ compared to BD, they had equal rates of personal recovery and emotional wellbeing. Personal recovery overlapped more with emotional wellbeing than with clinical recovery (χ2). Each participant was assigned to one of eight possible outcome groups depending on the combination of positive outcomes fulfilled. The eight groups collapsed into three equal-sized main outcome groups: 33.6% clinical recovery with personal recovery and/or emotional wellbeing; 34.4% personal recovery and/or emotional wellbeing only; and 32.0% none.
Conclusions
In FEP, 68% had minimum one positive outcome after 10 years, suggesting a good life with psychosis. This knowledge must be shared to instill hope and underlines that subjective and objective positive outcomes must be assessed and targeted in treatment.
In Sweden and in many other countries, a bentonite barrier will be used in the repository for spent nuclear fuel. In the event of canister failure, colloidal diffusion is a potential, but scarcely studied mechanism of radionuclide migration through the bentonite barrier. Column and in situ experiments are vital in understanding colloid diffusion and in providing information about the micro structure of compacted bentonite and identifying cut-off limits for colloid filtration. This study examined diffusion of negatively charged 2-, 5-, and 15-nm gold colloids in 4-month diffusion experiments using MX-80 Wyoming bentonite compacted to dry densities of 0.6–2.0 g/cm3. Breakthrough of gold colloids was not observed in any of the three diffusion experiments. In a gold-concentration profile analysis, colloid diffusion was only observed for the smallest gold colloids at the lowest dry density used (estimated apparent diffusivity Da ≈ 5 × 10−13 m2/s). The results from a microstructure investigation using low-angle X-ray diffraction suggest that at the lowest dry density used, interlayer transport of the smallest colloids cannot be ruled out as a potential diffusion pathway, in addition to the expected interparticle transport. In all other cases, with either greater dry densities or larger gold colloids, compacted bentonite will effectively prevent diffusion of negatively charged colloids due to filtration.
Bipolar I disorder is a mental disorder with the risk of severe clinical outcomes. Bipolar disorder was initially defined based on having a better outcome than schizophrenia. However, while recent longer-term findings in schizophrenia do not support neuroprogression, bipolar disorder is increasingly depicted as having neuroprogressive elements. There are, however, remarkably few prospective longitudinal studies of representative bipolar I cohorts followed from the first treatment.
Objectives
To study the clinical development of a representative cohort of bipolar disorder patients recruited at their first treatment.
Methods
Patients with DSM-IV Bipolar I or Bipolar NOS were consecutively recruited from in-and outpatient units in the larger Oslo area during their first treatment year and extensively clinically characterized at baseline. They then participated in personal one- and ten-year follow-ups.
Results
Sixty-nine patients participated in the 10-year follow-up. Age at follow-up was 39.0 (+ 9.6) years, 59% were females. A total of 12% had unipolar mania, 58% had psychotic bipolar disorder, and 20% had experienced rapid cycling. At follow-up, 75% were in full affective remission, 60% had regained full functioning, and 54% were in stable full recovery.
Mood episode relapses clustered around the first episode. Despite occasional relapses, 2/3 were mainly euthymic during the follow-up period. A small sub-group was highly affected from the first 2-3 years of treatment, but there were no apparent signs of kindling effects or indications of neuroprogression
Conclusions
The follow-up of this cohort of first-treatment Bipolar I patients does not support the hypothesis of neuroprogression.
Many people with lived experience from psychosis recover and thrive, contrary to the common stigmatizing belief that they will be chronic “patients”. But there are several ways to understand recovery, one is as a subjective process best explored through qualitative interviews with people who have recovered from psychosis. However, there is a need for more qualitative interview studies exploring what has been important for long-term subjective recovery for people with lived experience from psychosis outside of treatment. Exploring themes that are novel than previous research will have important clinical implications.
Objectives
This study aims to qualitatively explore what people with lived experience from psychosis believe has been the most important to attain and sustain their long-term personally defined recovery.
Methods
Qualitative interviews with 20 individuals participating in two follow-up-studies (TOP and TIPS-study) 10 and years 20 years after first treatment for a psychotic disorder (schizophrenia- or bipolar spectrum), respectively. All participants were in either clinical recovery (symptom remission and adequate functioning) or personal recovery (self-rated questionnaire) or both. Interviews were analyzed with thematic analysis in group meetings between the PhD-candidate, the main supervisor, a professor emerita in qualitative method and a co-researcher with lived experience from bipolar disorder.
Results
Participants defined recovery differently, but: “understanding myself”, “stable symptoms” and “finding the life that is right for you” were of the most common definitions. Tentatively, five main themes appear to be the most salient contributions to recovery: 1. Balance stress management with taking risks and following personal goals. 2. Accepting experience/”owning your story” in order to strategically disclose and manage stigma. 3. Taking agency over own recovery and mastery of everyday life. 4. Social support is crucial, but should change over time depending on need. 5. Feeling a sense of belonging to society does not need to entail “normality”.
Conclusions
Recovery was defined differently by each participant, but common themes across participants highlight that appropriate risk-taking, accepting your experience/owning your story, sense of agency, social support and inclusion are important to long-term recovery in psychosis.
Approximately 1/3 of patients with first episode psychosis (FEP) will not benefit from antipsychotic medications and are considered treatment resistant (TR). TR is currently defined as sustained lack of remission with functional loss in the context of two adequate trials of different antipsychotics. Studies suggest that early initiation of clozapine treatment support a better course of illness in TR. Most treatment guidelines recommend clozapine after two antipsychotic failures. In practice, increased dosages of other antipsychotics or polypharmacy are tried out first. Identifying early signs of TR and revising treatment is thus important. Since the TR definition requires adequate lengths of treatment attempts, they are difficult to apply in FEP.
Objectives
The aim of the current study is to 1) investigate if a shorter observation period can be used to identify subgroups of FEP patients with early signs of TR (no indication of early clinical recovery - NoECR) and 2) investigate differences in antipsychotic treatments over the first year compared to patients in full or partial early recovery (ECR/ partial ECR).
Methods
Participants 18 to 65 years in their first year of treatment were recruited from major hospitals in Oslo. The participants met the DSM-IV criteria for schizophrenia, schizophreniform disorder, schizoaffective disorder, and psychotic disorder NOS. A total of 387 completed baseline clinical assessments and 207 one-year follow-up. The SCID-I for DSM-IV was used for diagnosis, symptoms were measured with the SCI-PANSS. Treatment history was gathered through interviews and medical charts. No-ECR was defined as a) Not meeting remission criteria for at least 12 weeks at follow-up, and b) Not regained functioning, i.e., a GFS score < 60. ECR was defined as a) Meeting the criteria for remission and b) Regained functioning, i.e., a GFS score >=61. Partial ECR did not meet these criteria.
Results
At one year follow-up, 47% met the criteria for no-ECR, 29% the criteria for ECR and 24% the criteria for partial ECR. Baseline predictors of the no-ECR group corresponded to previously identified predictors of long-term TR. Only 35 (17%) participants met the full criteria for TR at this point. Of the 97 in the no-ECR group, 18 (19%) were in an ongoing trial (p<0.001 vs ECR/partial ECR) and 21 (22%) were using the same medication over the whole follow-up year (p =.008 vs ECR /partial ECR) despite lack of significant clinical effect.
Conclusions
We show that the mostly used consensus definition of TR identifies only a proportion of FEP patients without sufficient clinical and functional improvement at one year follow-up. The main reason for not meeting the criteria is a lack of two adequate antipsychotic trials at this point of time. However, only half of these were in an ongoing trial despite recommendations in clinical guidelines.
Major depressive disorder (MDD) is a common and severe mental disorder. Although inpatient care may be needed in some cases, little is known on which factors are associated with risk for readmission.
Objectives
To identify risk factors associated with an increased risk of readmission within 90 days, after being discharged from psychiatric inpatient care for depression.
Methods
A medical record review is ongoing based on consecutive inpatients admitted in 2019-2021 at Sahlgrenska University Hospital, in Sweden. Inclusion criteria are MDD-diagnosis, admission > 7 days, no admission during the past half-year. Exclusion criteria are blocked medical record, patients who expired within 90 days after discharge. Time to first readmission for discharged patients was examined within 90 days. Clinical and sociodemographic characteristics were compared between readmitted and no-readmitted patients.
Results
To date, 446 cases have been included with a readmission rate of 19.5%. In a subgroup of 182 patients (admitted between April 2020 and March 2021), psychotic subtype of depression seems to be protective to re-admission (p < .003) while comorbid eating (p < .017) and neurodevelopmental disorder (p < .029) seem to be associated with high risk. At the congress, results from the whole cohort will be presented.
Conclusions
Medical record reviews can give good clinically relevant data for prediction of readmission. Comorbidities and depression subtypes may affect the risk for readmission.
Visual hallucinations are a common symptom across psychotic disorders and have been linked to illness severity, impaired functioning, and increased suicide risk. However, little is known about the stability of this relationship over the long-term course of illness.
Objectives
This study aims to assess whether the presence of visual hallucinations is associated with illness severity, functioning and suicidality, early and late in the course of illness. It further explores the potential role of childhood trauma in this context, which has been linked to both visual hallucinations and suicidality.
Methods
A sample of 185 individuals with first-episode psychosis was assessed with structured clinical interviews and self-report questionnaires at time of study inclusion and at 10-year follow-up. Those with lifetime experience of visual hallucinations at inclusion (VH+/+) as well as those where visual hallucinations first developed during the follow-up period (VH-/+) were compared to a group without such experiences (VH-/-). To this end, multinomial logistic regression models were applied, with a range of clinical and demographic variables as predictors.
Results
At time of inclusion, the VH+/+ group had significantly higher symptom severity scores, lower functioning scores, and were more likely to have a history of multiple suicide attempts. There were no such differences between the VH-/+ and the VH-/- group. At follow-up, this pattern of findings partially reversed. Here, only the VH-/+ group differed from the VH-/- group in terms of higher symptom severity scores and lower functioning scores. However, the VH+/+ group was still more likely to report multiple suicide attempts during the follow-up period, whereas VH-/+ did not differ from VH-/-. Notably, childhood trauma scores did not differ between groups.
Conclusions
In line with previous studies, these findings point to an association between visual hallucinations and illness severity, functioning and suicidality. However, this association seems to change over the course of illness. Together, this highlights the relevance of assessing visual hallucinations in the clinical setting and monitoring their development over time.
One of the challenging features in the classification of of-binominals is distinguishing between the syntactically very similar forms. Therefore, Chapter 2 presents a variety of diagnostic tests in order to tease apart the constructions in the evaluative binominal noun phrase family. This chapter presents a comprehensive overview and discussion of the tests used in previous studies resulting in the following classification criteria: head status (Noun 1 or Noun 2), constituency tests, constraints on the selection of the two nouns, determiner selection restrictions, and the status of the preposition of. These tests are then used to classify all six of the of-binominals addressed in this study.
The classification criteria in Chapter 2 are now applied to the final three evaluative of-binominals. The evaluative binominal noun phrase (an egg of a head) is an of-binominal construction in which the first noun ascribes a property to the second. The second noun is head, and the construction exhibits a number of noncanonical syntactic features, e.g. the first determiner has scope over the whole construction, a restricted second determiner, and irregular premodification patterns. The evaluative modifier (a whale of a time) is a new of-binominal that I propose. In the evaluative modifier, the first noun has completely decategorizated and functions as a part of the [N1 of a] chunk that denotes speaker evaluation of the referent denoted by the second noun. Furthermore, I argue that this construction needs to be distinguished from the EBNP. Finally, in the binominal intensifier (a beast of a good read), [N1 of a] functions as an intensifier or booster, modifying the gradable adjectives that follow. This study demonstrates that this final construction is much more prolific than previous research has shown.
The three case studies presented in this chapter demonstrate that the six of-binominals introduced in Chapters 3 and 4 form a grammaticalization path, starting at the N+PP and ending, in most cases, at the BI (cake is the exception). The chapter begins with a discussion about the differences between grammaticalization and lexicalization, since both processes are plausible in this case. Then, looking at the first nouns beast, cake and hell (an animate, inanimate, and abstract first noun respectively) and using a range of historical corpora, this chapter presents a qualitative diachronic analysis that looks at first attestations of and discusses the use of these first nouns in the six of-binominal constructions presented in Chapters 3 and 4. Ultimately this chapter substantiates the claim that first nouns progress from the N+PP to the head-classifier, in some cases pseudo-partitive, then the EBNP, the EM, and the BI. Furthermore, it argues that the process demonstrated is indeed grammaticalization rather than lexicalization.
The chapter begins with an introduction to the FDG theory and language model. The discussion includes some of the issues in the classification of premodifiers and compares the distinctions made in FDG with the construction-based model. The second section presents an FDG model of each of-binominal, illustrating how the model captures the differences between these constructions. By doing so, current issues in recent FDG research are addressed, such as the role of CxG like constructions in FDG, interfaces and mismatches between levels, and the distinction between operators and modifiers. One important finding is that FDG predicts the changes of premodification patterns found in Chapter 7. The historical analysis in the FDG frameworks shows that we are looking at the reduction of the internal components of the N-of-N template to a simple NP template, with a reanalyzed chunk [N of (a)], functioning first as a modifier and then as a lexical operator. Therefore, although we are structurally looking at an of-binominal, this term is actually a misnomer
The chapter begins with a brief overview of research on the of-binominal, in general, before focusing on the constructions addressed in this study. It presents the constructions discussed in this work: prototypical N+PP, head-classifier, pseudo-partitive, evaluative binominal noun phrase, evaluative modifier, and binominal intensifier, and the research gap that the monograph fills. Furthermore, it briefly introduces the two theories used: Construction Grammar (CxG) and Functional Discourse Grammar (FDG) and presents the rationale behind examining the results from two theoretical paradigms. This chapter, furthermore, explains the choice of corpora used in the research (primarily the Corpus of Contemporary American English (COCA) and the Corpus of Historical American English (COHA) and details the construction of the dataset: those constructions included and excluded from the data set.
