Exploring the inherent resilience of health districts in a context of chronic armed conflict: a case study in Eastern Democratic Republic of the Congo.

Background: In South Kivu (Eastern Democratic Republic of the Congo [DRC]), health districts (HDs) affected by chronic armed conflicts are devising coping mechanisms to continue offering healthcare services to the population. Nonetheless, this alone does not suffice to make them fully resilient to such conflicts. This study aims to explore the characteristics of these HDs' resilience.

Which socio-economic groups benefit most from public health expenditure in Senegal? A dynamic benefit incidence analysis.

Despite efforts to enhance public investment in Senegal's health sector, the equitable distribution of benefits between socioeconomic groups remains largely unexplored. To address this gap, our study examines the progressive (or regressive) nature of public health expenditure. Utilizing data from the latest survey on household living conditions (2018-2019) in conjunction with administrative data on health expenditure from the same period (provided by the Ministry of Health of Senegal), we performed a benefit incidence analysis.

Who is "anti-science"?

Objectives: "Anti-science" accusations are common in medicine and public health, sometimes to discredit scientists who hold opposing views. However, there is no such thing as "one science". Epistemology recognizes that any "science" is sociologically embedded, and therefore contextual and intersubjective.

Contributions of Polygenic Risk and Disease Status to Gray Matter Abnormalities in Major Depression.

Background: Gray matter (GM) abnormalities in depression are potentially attributable to some combination of trait, state, and illness history factors. Here, we sought to determine the contributions of polygenic risk for depression, depressive disease status, and the interaction of these factors to these GM abnormalities.

Methods: We conducted a cross-sectional comparison using a 2 × 3 factorial design examining effects of polygenic risk for depression (lower vs.

Multivariate analyses of immune markers reveal increases in plasma EN-RAGE in first-episode psychosis patients.

Immune cells and cytokines are largely recognized as significant factors in the pathophysiology of neuropsychiatric disorders. The possible role of other blood cells such as leukocytes in events of acute psychosis is in contrast only emerging. To study blood-born markers in acute psychosis we here evaluated plasma proteins in drug-naive first-episode psychosis (FEP) patients and healthy controls using a multiplex proximity extension assay technique.

[Mapping and analysis of health financing in South Kivu province (DRC)].

Introduction: In South-Kivu, the health system is underfunded due to numerous constraints. Several initiatives have been tested but are insufficient for increasing and sustaining health financing.

Purpose Of Research: Analyze the health financing system in South-Kivu, through a mapping as well as quantitative and qualitative analysis of health financing mechanisms.

Mandatory membership of community-based mutual health insurance in Senegal: A national survey.

With the low adherence to voluntary mutual health insurance, Senegal's policymakers have sought to understand the feasibility of compulsory health insurance membership. This study aims to measure the acceptability of mandatory membership in community-based mutual health insurance (CBHI) and to understand its possible administrative modalities. The study consists of a national survey among a representative population sample selected by marginal quotas.

Surfing Corona waves - instead of breaking them: Rethinking the role of natural immunity in COVID-19 policy.

In the first two years of the pandemic, COVID-19 response policies have aimed to break Corona waves through non-pharmaceutical interventions and mass vaccination. However, for long-term strategies to be effective and efficient, and to avoid massive disruption and social harms, it is crucial to introduce the role of natural immunity in our thinking about COVID-19  (or future "Disease-X") control and prevention. We argue that any Corona or similar virus control policy must appropriately balance five key elements simultaneously: balancing the various fundamental interests of the nation, as well as the various interventions within the health sector; tailoring the prevention measures and treatments to individual needs; limiting social interaction restrictions; and balancing the role of vaccinations against the role of naturally induced immunity.

Towards a multilevel model of major depression: genes, immuno-metabolic function, and cortico-striatal signaling.

Biological assay and imaging techniques have made visible a great deal of the machinery of mental illness. Over fifty years of investigation of mood disorders using these technologies has identified several biological regularities in these disorders. Here we present a narrative connecting genetic, cytokine, neurotransmitter, and neural-systems-level findings in major depressive disorder (MDD).

Human endogenous oxytocin and its neural correlates show adaptive responses to social touch based on recent social context.

Both oxytocin (OT) and touch are key mediators of social attachment. In rodents, tactile stimulation elicits the endogenous release of OT, potentially facilitating attachment and other forms of prosocial behavior, yet the relationship between endogenous OT and neural modulation remains unexplored in humans. Using a serial sampling of plasma hormone levels during functional neuroimaging across two successive social interactions, we show that contextual circumstances of social touch influence not only current hormonal and brain responses but also responses.

COVAX - Time to reconsider the strategy and its target.

COVAX, the international initiative supporting COVID-19 vaccination campaigns globally, is budgeted to be the costliest public health initiative in low- and middle-income countries, with over 16 billion US dollars already committed. While some claim that the target of vaccinating 70% of people worldwide is justified on equity grounds, we argue that this rationale is wrong for two reasons. First, mass COVID-19 vaccination campaigns do not meet standard public health requirements for clear expected benefit, based on costs, disease burden and intervention effectiveness.

Resilience to substance use disorder following childhood maltreatment: association with peripheral biomarkers of endocannabinoid function and neural indices of emotion regulation.

Childhood maltreatment (CM) is a risk factor for substance use disorders (SUD) in adulthood. Understanding the mechanisms by which people are susceptible or resilient to developing SUD after exposure to CM is important for improving intervention. This case-control study investigated the impact of prospectively assessed CM on biomarkers of endocannabinoid function and emotion regulation in relation to the susceptibility or resilience to developing SUD.

Functional connectivity signatures of major depressive disorder: machine learning analysis of two multicenter neuroimaging studies.

The promise of machine learning has fueled the hope for developing diagnostic tools for psychiatry. Initial studies showed high accuracy for the identification of major depressive disorder (MDD) with resting-state connectivity, but progress has been hampered by the absence of large datasets. Here we used regular machine learning and advanced deep learning algorithms to differentiate patients with MDD from healthy controls and identify neurophysiological signatures of depression in two of the largest resting-state datasets for MDD.

Expectations and disappointments relative to COVID-19 passes: results from a voluntary mixed-methods study in French-speaking Belgium.

Objectives: Belgium enacted a coronavirus disease 2019 (COVID-19) pass - the 'COVID Safe Ticket' (CST) - in October 2021. This study aimed to understand the expectations and reasons given by those supporting this policy measure.

Methods: This mixed methods study was based on a voluntary online survey among 9444 French-speaking residents in Belgium.

Adaptive Mechanisms of Health Zones to Chronic Traumatic Events in Eastern DRC: A Multiple Case Study.

Background: The Eastern part of the Democratic Republic of Congo (DRC) has been affected by armed conflict for several years. Despite the growing interest in the impact of these conflicts on health service utilisation, few studies have addressed the coping mechanisms of the health system. The purpose of this study is to describe the traumatic events and coping mechanisms used by the health zones (HZs) in conflict settings to maintain good performance.

Objective: The study aims to assess the level of implementation of road safety interventions in Benin.

Method: The research is based on an evaluative study of road safety aimed to analyze the implementation and logic of road safety interventions, conducted in Benin in 2019. It combined a review of the gray literature and a qualitative component.

Formal and informal medicine retailers in Sub-Saharan Africa: a scoping review of research trends.

Objectives: In Sub-Saharan Africa (SSA), private medicine retailers have become the first entry point to health systems, irrespective of their level of accreditation. This review aims to map the main trends in research about formal and informal medicine retailers in SSA over the past 20 years. Such an overview offers a valuable resource to understand their role and develop inclusive interventions to improve accessibility to health care in line with people's health-seeking behaviours.

Peripheral and central kynurenine pathway abnormalities in major depression.

Considerable data relate major depressive disorder (MDD) with aberrant immune system functioning. Pro-inflammatory cytokines facilitate metabolism of tryptophan along the kynurenine pathway (KP) putatively resulting in reduced neuroprotective and increased neurotoxic KP metabolites in MDD, in addition to modulating metabolic and immune function. This central nervous system hypothesis has, however, only been tested in the periphery.

The danger of the single storyline obfuscating the complexities of managing SARS-CoV-2/COVID-19.

Chimamanda Ngozi Adichie showed how a single story is limited and thereby distorts the true nature of an issue. During this COVID-19 pandemic there have been, at least, three consecutive single stories-the 'lethal threat' story, followed by the 'economic threat' story, and finally the 'vaccine miracle' story. None of these single stories can convincingly and permanently capture the dynamics of the pandemic.

Psilocybin targets a common molecular mechanism for cognitive impairment and increased craving in alcoholism.

Alcohol-dependent patients commonly show impairments in executive functions that facilitate craving and can lead to relapse. However, the molecular mechanisms leading to executive dysfunction in alcoholism are poorly understood, and new effective pharmacological treatments are desired. Here, using a bidirectional neuromodulation approach, we demonstrate a causal link between reduced prefrontal mGluR2 function and both impaired executive control and alcohol craving.

COVID-19: an 'extraterrestrial' disease?

Background: Since the beginning of the pandemic, COVID-19 has been regarded as an exceptional disease. Control measures have exclusively focused on 'the virus', while failing to account for other biological and social factors that determine severe forms of the disease.

Aim: We argue that although COVID-19 was initially considered a new challenge, justifying extraordinary response measures, this situation has changed - and so should our response.
