    Concerted efforts have been made in recent years to achieve equity and equality in mental health for all people across the globe. This has led to the emergence of Global Mental Health as an area of study and practice. The momentum that this has created has contributed to the development, implementation and evaluation of services for priority mental disorders in many low- and middle-income countries. This paper discusses two related issues that may be serving to limit the success of mental health initiatives across the globe, and proposes potential solutions to these issues. First, there has been a lack of sophistication in determining what constitutes a ‘good outcome’ for people experiencing mental health difficulties. Even though health is defined and understood as a state of ‘wellbeing’ and not merely an absence of illness, mental health interventions tend to narrowly focus on reducing symptoms of mental illness. The need to also focus more broadly on enhancing subjective wellbeing is highlighted. The second limitation relates to the lack of an overarching theoretical framework guiding efforts to reduce inequalities and inequities in mental health across the globe. This paper discusses the potential impact that the Capabilities Approach (CA) could have for addressing both of these issues. As a framework for human development, the CA places emphasis on promoting wellbeing through enabling people to realise their capabilities and engage in behaviours that they subjectively value. The utilization of the CA to guide the development and implementation of mental health interventions can help Global Mental Health initiatives to identify sources of social inequality and structural violence that may impede freedom and individuals’ opportunities to realise their capabilities

    Analysis of four mature cell markers on mouse bone marrow leukocytes grown in vitro, demonstrated a distinct sequence of marker appearance during the terminal phases of granulocytic cell differentiation. A similar pattern of marker expression was also suggested by analysis of mature neutrophils and macrophages isolated from normal tissues. Among cultured neutrophils, receptors for the Fc portion of IgG (FcR) were first expressed on myelocytes and metamyelocytes, and then subsequently on more mature cells. Morphologically mature colony neutrophils (polymorphs) from agar cultures contained only FcR and complement receptor type two (CR(2)) (C3d receptor), and lacked both complement receptor type one (CR(1)) (C3b receptor) and the capacity to ingest latex, bacteria, or iron particles. Neutrophils from 2 and 3 wk liquid media cultures of marrow cells differed from agar grown neutrophils in that they had phagocytic capacity (particle ingestion) [Pi] in addition to FcR and CR(2). Furthermore, in the 4th and 5th wk of these continuous liquid cultures, CR(1) was also expressed, completing the surface marker profile of normal blood neutrophils. Based on these studies, the following order of appearance of these four markers on cells from the myelocytic series was proposed: FcR {arrow} FcR CR(2) {arrow} FcR CR(2) Pi {arrow} FcR CR(2) Pi CR(1). Differential studies of tissue leukocytes containing these same markers revealed that a heterogeneity existed among morphologically mature neutrophils. Even though 95 percent of blood polymorphs contained all four markers, the same was true of only half of spleen polymorphs and only 20 percent of bone marrow polymorphs. Cells of the monocyte-macrophage series were studies in parallel with neutrophils. Cultured marrow monocytes acquired the four mature cell markers so rapidly that the order of receptor appearance could not be determined. However, it was found that CR2 was lost during the terminal phase of monocyte maturation into activated macrophages

    Probabilistic Analysis of Optimization Problems on Generalized Random Shortest Path Metrics

    Simple heuristics often show a remarkable performance in practice for optimization problems. Worst-case analysis often falls short of explaining this performance. Because of this, "beyond worst-case analysis" of algorithms has recently gained a lot of attention, including probabilistic analysis of algorithms. The instances of many optimization problems are essentially a discrete metric space. Probabilistic analysis for such metric optimization problems has nevertheless mostly been conducted on instances drawn from Euclidean space, which provides a structure that is usually heavily exploited in the analysis. However, most instances from practice are not Euclidean. Little work has been done on metric instances drawn from other, more realistic, distributions. Some initial results have been obtained by Bringmann et al. (Algorithmica, 2013), who have used random shortest path metrics on complete graphs to analyze heuristics. The goal of this paper is to generalize these findings to non-complete graphs, especially Erd\H{o}s-R\'enyi random graphs. A random shortest path metric is constructed by drawing independent random edge weights for each edge in the graph and setting the distance between every pair of vertices to the length of a shortest path between them with respect to the drawn weights. For such instances, we prove that the greedy heuristic for the minimum distance maximum matching problem, the nearest neighbor and insertion heuristics for the traveling salesman problem, and a trivial heuristic for the kk-median problem all achieve a constant expected approximation ratio. Additionally, we show a polynomial upper bound for the expected number of iterations of the 2-opt heuristic for the traveling salesman problem.Comment: An extended abstract appeared in the proceedings of WALCOM 201

    For 25 years, the Council on Foundations and Candid have partnered on studies of globally focused giving by U.S. foundations. The new edition of The State of Global Giving by U.S. Foundations dives into 2016-2019 data to provide the latest perspective on how the nation's foundations are supporting critical efforts to improve health outcomes, address climate change, offer access to education, ensure human rights, and engage with a wide array of other global priorities. Through interviews with a selection of global funders, Global Giving also offers insights on how foundations are addressing the critical challenges of our time and where they see signs of optimism and opportunity going forward.Key Report FindingsU.S. private and community foundations included in Candid's Foundation 1000 dataset awarded globally focused grants totaling 8billionin2019closetofourtimestheapproximately8 billion in 2019—close to four times the approximately 2.2 billion awarded in 2002.Health accounted for 49 percent of global grant dollars.The largest shares of funding focused on the Sub-Saharan Africa (25.1%) and Asia & Pacific (17.7%) regions.Among the many issue areas supported by foundations, human rights has realized the fastest growth in global support in recent years. In the 2016-2019 period, human rights reached 11 percent of global foundation grant dollars, up from less than 7 percent in the 2011-2015 period.Roughly 13 percent of U.S. foundations' global grant dollars went directly to organizations based in the country where programs were implemented in the 2016-2019 period, up marginally from approximately 12 percent in the 2011-2015 period.Funding by Foundation 1000 foundations for efforts to counter or mitigate the impact of climate change in the United States and globally totaled nearly 1.8billioninthe20162019period,upfrom1.8 billion in the 2016-2019 period, up from 1.3 billion in the 2011-2015 period.The Bill & Melinda Gates Foundation accounted for 44% of global giving by U.S. foundations from 2016 to 2019

    Hvordan opprettholder sykepleier menneskeverdet hos pasienter med demensdiagnose under tvangsutøvelse på sykehjem?

    Sykepleiere møter utfordringer når de skal foreta beslutningen om å utføre tvang eller ikke etter Pasient- og brukerrettighetsloven §4 A. Spesielt i de tilfellene som omfatter «nødvendig helsehjelp» og hvor de også må sørge for at pasientens menneskeverd blir ivaretatt. Hensikt: Hensikten med oppgaven er å belyse hvordan sykepleiere opprettholder menneskeverdet hos beboere på sykehjem med demensdiagnose når de må utøve tvang. Metode: Vi har foretatt en integrativ litteraturstudie. Både de fire vitenskapelige forskningsartikler vi har valgt ut, samt annen relevant litteratur og egne erfaringer utgjør grunnlaget for vår besvarelse av bacheloroppgaven. Resultater: Bruk av tvang i seg selv er krenkende, men i en situasjon hvor «nødvendig helsehjelp» må gis og tvang ikke benyttes, blir menneskeverdet ikke ivaretatt. Så lenge alle tillitsskapende tiltak blir utført før tvangsbruk, ivaretas pasienten sitt menneskeverd.Background: Nurses face challenges in deciding whether to use or not to use coercion under Patients and user rights act § 4A. It is especially during critical situations where nurses need to provide necessary care, and at the same time they have to make sure that the patients´ human dignity is preserved. Purpose: The aim of the study is to inform readers on how nurses can protect patients´ dignity with dementia in nursing homes during coercion. Method: We conducted an integrative literature review in our paper. Four empirical research papers were analysed, together with other related theoretical literature ,and at the same time our clinical experience which serves as a basis to answer our research question. Result: The act of using coercion during patient care is both offensive and insulting. However, the act of coercion can preserve patients’ dignity especially during critical situations where the use of coercion is a must. As long as all the «confidence-building initiative» strategies have been fulfilled before the act of coercion itself, thus patients´dignity is preserved

    Knee instruments and rating scales designed to measure outcomes

    In this article, the knee instruments and rating scales that are designed to measure outcomes are revised. Although the International Knee Documentation Committee Subjective Knee Form can be used as a general knee measure, no instrument is currently universally applicable across the spectrum of knee disorders and patient groups. Clinicians and researchers looking to use a patient-based score for measurement of outcomes must consider the specific patient population in which it has been evaluated. The Western Ontario and McMaster Universities Osteoarthritis Index is recommended for the evaluation of treatment effect in persons with osteoarthritis (OA). This is a generic health status questionnaire that contains 36 items, is widely used, and easy to complete. The Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire evaluates the functional status and quality of life (QoL) of patients with any type of knee injury who are at increased risk of developing OA; i.e., patients with anterior cruciate ligament (ACL) injury, meniscus injury, or chondral injury. So far, the KOOS questionnaire has been validated for several orthopedic procedures such as total knee arthroplasty, ACL reconstruction, and meniscectomy. The utilization of QoL questionnaires is crucial to the adequate assessment of a number of orthopedic procedures of the knee. The questionnaires are generally well accepted by the patients and open up new perspectives in the analysis of prognostic factors for optimal QoL of patients undergoing knee surgery

    T Cell/B Cell Collaboration and Autoimmunity: An Intimate Relationship

    Get PDF
    Co-ordinated interaction between distinct cell types is a hallmark of successful immune function. A striking example of this is the carefully orchestrated cooperation between helper T cells and B cells that occurs during the initiation and fine-tuning of T-cell dependent antibody responses. While these processes have evolved to permit rapid immune defense against infection, it is becoming increasingly clear that such interactions can also underpin the development of autoimmunity. Here we discuss a selection of cellular and molecular pathways that mediate T cell/B cell collaboration and highlight how in vivo models and genome wide association studies link them with autoimmune disease. In particular, we emphasize how CTLA-4-mediated regulation of CD28 signaling controls the engagement of secondary costimulatory pathways such as ICOS and OX40, and profoundly influences the capacity of T cells to provide B cell help. While our molecular understanding of the co-operation between T cells and B cells derives from analysis of secondary lymphoid tissues, emerging evidence suggests that subtly different rules may govern the interaction of T and B cells at ectopic sites during autoimmune inflammation. Accordingly, the phenotype of the T cells providing help at these sites includes notable distinctions, despite sharing core features with T cells imparting help in secondary lymphoid tissues. Finally, we highlight the interdependence of T cell and B cell responses and suggest that a significant beneficial impact of B cell depletion in autoimmune settings may be its detrimental effect on T cells engaged in molecular conversation with B cells

    Short Stat5-Interacting Peptide Derived from Phospholipase C-β3 Inhibits Hematopoietic Cell Proliferation and Myeloid Differentiation

    Constitutive activation of the transcription factor Stat5 in hematopoietic stem/progenitor cells leads to various hematopoietic malignancies including myeloproliferative neoplasm (MPN). Our recent study found that phospholipase C (PLC)-β3 is a novel tumor suppressor involved in MPN, lymphoma and other tumors. Stat5 activity is negatively regulated by the SH2 domain-containing protein phosphatase SHP-1 in a PLC-β3-dependent manner. PLC-β3 can form the multimolecular SPS complex together with SHP-1 and Stat5. The close physical proximity of SHP-1 and Stat5 brought about by interacting with the C-terminal segment of PLC-β3 (PLC-β3-CT) accelerates SHP-1-mediated dephosphorylation of Stat5. Here we identify the minimal sequences within PLC-β3-CT required for its tumor suppressor function. Two of the three Stat5-binding noncontiguous regions, one of which also binds SHP-1, substantially inhibited in vitro proliferation of Ba/F3 cells. Surprisingly, an 11-residue Stat5-binding peptide (residues 988-998) suppressed Stat5 activity in Ba/F3 cells and in vivo proliferation and myeloid differentiation of hematopoietic stem/progenitor cells. Therefore, this study further defines PLC-β3-CT as the Stat5- and SHP-1-binding domain by identifying minimal functional sequences of PLC-β3 for its tumor suppressor function and implies their potential utility in the control of hematopoietic malignancies

    Lower prevalence of hip fractures in foreign-born individuals than in Swedish-born individuals during the period 1987-1999

    <p>Abstract</p> <p>Background</p> <p>This is the first longitudinal study with a 22-year follow-up, based on a national and complete sample, to determine whether the prevalence of hip fracture and the age when it occurs are influenced by migration and by being foreign-born. Cultural background and environmental factors such as UV-radiation and lifestyle during childhood and adolescence may influence the risk of a hip fracture event later in life. Differences in prevalence might occur between the indigenous population and those who have migrated to a country.</p> <p>Methods</p> <p>The study was based on national population data. The study population consisted of 321,407 Swedish-born and 307,174 foreign-born persons living in Sweden during the period 1987-1999.</p> <p>Results</p> <p>Foreign-born individuals had a reduced risk of hip fracture, with odds ratios (ORs) of 0.47-0.77 for men and 0.42-0.88 for women. Foreign-born women had the hip fracture event at a higher age on average, but a longer time spent in Sweden was associated with a small but significant increase in risk.</p> <p>Conclusions</p> <p>We found that there was a reduced risk of hip fracture in all foreign-born individuals, and that the hip fracture event generally happened at a higher age in foreign-born women. Migration must therefore be considered in relation to the prevalence and risk of hip fracture. Migration can therefore have a positive effect on one aspect of the health of a population, and can influence and lower the total cost of healthcare due to reduced risk and prevalence of hip fracture.</p

    Follicular helper T cell profiles predict response to costimulation blockade in type 1 diabetes

    Follicular helper T (TFH) cells are implicated in type 1 diabetes (T1D), and their development has been linked to CD28 costimulation. We tested whether TFH cells were decreased by costimulation blockade using the CTLA-4–immunoglobulin (Ig) fusion protein (abatacept) in a mouse model of diabetes and in individuals with new-onset T1D. Unbiased bioinformatics analysis identified that inducible costimulatory molecule (ICOS)+ TFH cells and other ICOS+ populations, including peripheral helper T cells, were highly sensitive to costimulation blockade. We used pretreatment TFH profiles to derive a model that could predict clinical response to abatacept in individuals with T1D. Using two independent approaches, we demonstrated that higher frequencies of ICOS+ TFH cells at baseline were associated with a poor clinical response following abatacept administration. Therefore, TFH analysis may represent a new stratification tool, permitting the identification of individuals most likely to benefit from costimulation blockade
